Background. Topography of the appendix influences its mobility, degree of mobilization of the cecum, and need for additional muscle splitting during appendectomy. Although appendectomy is a common surgical procedure, there is a paucity of data on its topography in black Africans. Methods. The position and length of the appendix and relation of the appendicular base with spinoumbilical line were determined in 48 cadavers obtained from the Department of Human Anatomy, University of Nairobi, Kenya. Results. The commonest appendicular types in males were retrocecal 10 (27&\#x25;) while in females was subileal 4 (36.4&\#x25;). The average length of the appendix was 76.5 &\#xb1; 23.6&\#x2009;mm. The base of the appendix was located along, below, and above the spinoumbilical line in 25 (52.1&\#x25;), 9 (18.8&\#x25;), and 14 (29.2&\#x25;) cases, respectively. Conclusion. The topography of appendix in Kenyans shows variations from other populations. Knowledge of these variations is important during appendicectomy.

Ogeng’o J. "VARIATIONS OF PULMONARY VEINS AND THEIR CLINICAL RELEVANCE." Anatomy Journal of Africa. . 2016;5(2):702-703. Abstract

Variations of pulmonary veins (PV) were previously considered rare, only documented as isolated case reports.
Recent cadaveric, autopsy, CT, MDCT and MRI studies have revealed substantial variations with respect to their
number and drainage pattern into the left atrium (Marom et al., 2004; Calkins et al., 2007; Wannasopha et al.,
2012; Harbi et al., 2014; Rajguru and Fulzele, 2016). The most commonly described variations include
supernumerary or less pulmonary veins and the corresponding arterial ostia. The article in this issue
(Kinfemichael and Dawit, 2016) presents a case of 5th pulmonary vein originating from the middle lobe of the
right lung. This is consistent with previous reports of supernumerary pulmonary veins and ostia (Marom et al.,
2004; Calkins et al., 2007; Prasanna et al., 2014). These vary from 2 – 7 (Wei et al., 2014; Yuan et al., 2015;
Rajguru and Fulzele, 2016; Kumzel – Piotrowska et al., 2016). The commonest cause of such variations is the
right middle pulmonary vein (Calkins et al., 2007; Klimek – Piotrowska et al., 2016). These variations have
informed various classifications based on number of pulmonary veins and ostia (Marom et al., 2004). One of the
most straight forward classifications was proposed by Shukla et al (2012). The principle of this classification in
the table below may be extended to include, say type VI or VII depending on the number of veins.

PURPOSE: The purpose of this study was to describe variations of the proximal segments of the superior cerebellar artery (SCA) detected by magnetic resonance (MR) angiography. MATERIALS AND METHODS: We reviewed 145 consecutive MR angiograms. All patients were studied with a 1.5-Tesla imager using the three-dimensional time-of-flight technique. RESULTS: There were 16 duplicated SCAs in 13 patients, seven SCAs originating from the posterior cerebral arteries in six patients, four early bifurcations of the SCAs in four patients, and one SCA arising from the internal carotid artery. Because the SCA is small in caliber, the bilateral SCAs in nine patients could not be identified on MR angiograms owing to patient movement. In two patients with duplicated SCA, one of the duplicated trunks compressed the trigeminal nerve at the root entry zone, resulting in trigeminal neuralgia. CONCLUSION: Although most of these SCA variations have no clinical significance, preoperative identification of SCA variations is important for avoiding complications during surgery and/or for interventional procedures of the distal basilar artery.

This paper evaluates the impact of variety awareness and nutrition knowledge on the adoption of biofortified crop varieties using a sample of 661 households from Kisii and Nyamira counties in Kenya. The study employs the average treatment effect (ATE) framework to control for information on the KK15 bean variety and knowledge of its nutritional attributes among small-scale farmers. The results show that farmers who had knowledge of the nutritional attributes of KK15 beans were more likely to adopt relative to those who were only aware of the variety. A nutrition attribute knowledge gap of 8% was estimated, which represents the potential adoption loss due to a lack of knowledge of the nutritional benefits. Adoption of biofortified crops can therefore be improved by disseminating information on the varieties and their nutritional attributes. This can be achieved by entrenching nutrition information in extension packages disseminated to farmers.

Like any other diseases of poultry, tumours are important to poultry keepers. This is because farmers keep poultry mainly for commercial purposes and are affected by any condition that would cau se death of the chickens or reduce their productivity. There are various tumours that affect chickens, mostly the older ones. This is a report of two manifestations of ovarian carcinoma and two extraordinary manifestations of Marek’s disease/Leucosis compl ex observed in Kenya. Possible impacts on poultry production are discussed.

Ogeng’o JA, Mwachaka PM, Olabu BO. "Vasa Vasora in the Tunica Media of Goat Aorta." International Journal of Morphology. 2011;29(3):702-705. Abstract

This study aimed at describing the distribution of vasa vasora in the tunica media of various parts of goat aorta, since this influences the physico-mechanical properties and disease occurrence. Specimens were obtained from ascending, arch, each vertebral level of descending thoracic and various segments of abdominal aorta of sixteen healthy adult male domestic goats (Capra hircus). They were fixed in 10% formaldehyde solution, and routinely processed for paraffin embedding. Seven micron thick sections were stained with Mason’s Trichrome stain. Vasa vasora are present in the tunica media of all the aortic segments. In the proximal segments, they co-localize with muscle islands found in the adventitial half. Their density declines caudally, but they are still present in the tunica media even in the abdominal aorta where the thickness is less than 0.5mm and elastic lamellae less than 29. Vasa vasora in the goat aortic tunica
media penetrate into the luminal half and are present even in relatively thin segments. This extent, which may enhance vascular health, suggests that the goat aortic wall is very active, a feature probably related to auxillary pump function of the muscle islands in the aortic wall

Heart (British Cardiac Society). 2013;99:48-54. Abstract

{OBJECTIVES: To serially investigate the relationship between vasa vasorum (VV) proliferation and plaque progression in vivo, and the effects of atorvastatin on VV and atherosclerosis as assessed by contrast-enhanced ultrasound (CEUS) and intravascular ultrasound (IVUS) imaging. METHODS: Carotid atherosclerosis was induced in rabbits with a high-cholesterol diet for 20 weeks and balloon injury. At week 16, following the imaging of the right common carotid arteries by CEUS and IVUS, 20 rabbits were randomised into a control or atorvastatin group (2 mg/kg/day). At week 20, CEUS and IVUS were repeated. Normalised maximal video-intensity enhancement (MVE) was calculated to quantify the density of VV. Plaque volume was determined by IVUS. RESULTS: When compared with the control group, lipid levels were not significantly lower following 4 weeks of atorvastatin administration. The increases in the normalised MVE over time were greater in the control group than in the atorvastatin group (p=0.001). The increase in plaque volume from 16 to 20 weeks was significantly greater in the control group than in the atorvastatin group (p=0.001). There was a positive relationship between changes in normalised MVE and plaque volume (r=0.72

Mulligan-Kehoe MJ. "The vasa vasorum in diseased and nondiseased arteries." American Journal of Physiology - Heart and Circulatory Physiology. 2010;298:H295-H305. AbstractWebsite

The vasa vasorum form a network of microvasculature that originate primarily in the adventitial layer of large arteries. These vessels supply oxygen and nutrients to the outer layers of the arterial wall. The expansion of the vasa vasorum to the second order is associated with neovascularization related to progression of atherosclerosis. Immunohistological analysis of human plaques from autopsied aortas have defined plaque progression and show a significant correlation with vasa vasorum neovascularization. Recent technological advances in microcomputed tomography have enabled investigation of vasa vasorum structure and function in nondiseased large arteries from pigs and dogs. Smaller mammals, particularly mice with genetic modifications that enable disease development, have been used extensively to study the vasa vasorum in diseased vessels. Despite the fact that most mouse models that are used to study atherosclerosis are unable to develop plaque to the extent found in humans, studies in both humans and mice underscore the importance of angiogenic vasa vasorum in progression of atherosclerosis. Those who have examined the vasa vasorum in occluded vessels of nondiseased pigs and dogs find that inhibition of the vasa vasorum makes the animals atheroprone. Atherosclerosis is a multifactorial disease. There is increasing evidence that factors, produced in response to changes in the arterial wall, collaborate with the vasa vasorum to enhance the disease process.

Ngugi PN, MCLIGEYO SO, KAYIMA JK, Otieno LS, Mogere R. "Vascular access for haemodialysis.". 1991. Abstract

In a fifteen month period (August 1987 to November 1988) forty patients requiring haemodialysis had 83 angioaccess procedures performed. Arteriovenous (AV) shunts and arteriovenous fistulae were the commonest procedures, comprising 56 (67%) and 20 (24%) of the patients respectively. Subclavian catheters and artificial grafts were used less frequently. Nephrologists and senior house officers attached to the Renal Unit were responsible for fashioning A-V shunts and inserting subclavian catheters while the A-V fistulae were fashioned by the urologists and vascular surgeons. The commonest complication of A-V shunts were clotting, occurring in 31 (55.4%) followed by bleeding in 14 (25%). Eight (32%) of the A-V fistulae never functioned from the beginning. It is noted that we are still very dependent on A-V shunts for vascular access in end stage renal disease (ESRF) patients and this is associated with an unacceptable level of complications. This dependency on A-V shunts in ESRD patients should be stopped or phased out. A-V fistulae should be used more frequently. Their constructions should be well thought out, executed and supervised by the few surgeons who are versed in them together with their follow-ups

"Vascular thrombosis in patients on chronic maintenance haemodialysis using indwelling venous catheters: Case reports and literature review." International Journal of Sciences: Basic and Applied Research. 2017;36(1):110-117. Abstract

Vascular access is key in patients with end stage renal disease on maintenance haemodialysis. Thrombosis is a
significant contributor of access – associated morbidity. There are several documented risk factors that
predispose to thrombosis in patients with end stage renal disease. These include: inflammation, erythropoietin
therapy, hypotension, diabetes and old age among others. Treatment of thrombosis in these patients is
challenging. We present three cases of acute vascular thrombosis attended to in the Kenyatta National Hospital,
Nairobi-Kenya, East Africa, renal department in one week and literature review.
Keywords: Vascular thrombosis; Haemodialysis catheter; endstage renal disease.

OBJECTIVE: To describe vasculitis in HIV patients, their CD4 levels, anatomical sites affected and clinical patterns. DESIGN: Prospective, descriptive study. SETTING: Kisumu District Hospital and Nairobi Rheumatology Clinic between January 2002 and May 2005. SUBJECTS: Eight patients with HIV and vasculitis. RESULTS: Eight patients (four males and four females) were recruited with an age range of 24-61 years, mean 33.13 years. Five had central nervous system vasculitis and three had peripheral vasculitis. The CD4 counts were low, range 2-200 cells/mm3 (mean of 79.25 cells/mm3), normal levels of CD4 are 355-1298 cells/mm3, indicating severe immunosuppression. Two patients tested positive for HBV (hepatitis B virus). CONCLUSION: HIV associated vasculitis is recognised and may be complicated by coinfection with hepatitis viruses. It occurs at low CD4 counts. Central nervous system involvement is a common site. Management is multidisciplinary.
W PROFGUTHUASYMON. "Vastardis H, Karimbux N, Guthua SW, Seidman JG, Seidman CE.A human MSX1 homeodomain missense mutation causes selective tooth agenesis.Nat Genet. 1996 Aug;13(4):417-21.". In: Nat Genet. 1996 Aug;13(4):417-21. Elsevier; 1996. Abstract
We demonstrate that a mutation in the homeobox gene, MSX1, causes a common developmental anomaly, familial tooth agenesis. Genetic linkage analyses in a family with autosomal dominant agenesis of second premolars and third molars identified a locus on chromosome 4p, where the MSX1 gene resides. Sequence analyses demonstrated an Arg31Pro missense mutation in the homeodomain of MSX1 in all affected family members. Arg 31 is a highly conserved homeodomain residue that interacts with the ribose phosphate backbone of target DNA. We propose that the Arg31 Pro mutatrion comprises MSX1 interactions, and suggest that MSX1 functions are critical for normal development of specific human teeth.
Oduor AS. "VAT." Sunday Standard (2013):11. Abstract

Pals, hereunder is my poem on VAT, whose abridged version was published on page 11 of the Sunday Magazine, of the Sunday Standard on September 29, 2013.

VAT

VAT, what is that?
Vatable, invertable, convertable,
Inclusive, exclusive and compulsive.
If all be vatable, what then is left?.

VAT on BAT, CAT, DAT, FAT,............and ZAT
Spare the parts, for a raid on gas is pinching the purse.
Essential goods and non-essential commodities, so all are paying through the nose;
Infants, elephants, guilty and innocent, all are instantly feeling the heat.

Make ammends and mend the fence before it is late, and irredeemable damage is done.
Capital flight is calmnly winning the fight,
Manufucturers are mindfully moving away and across,
Unemployment and all other social ills, will surely grow.

Consumers are spoiling for a fight, ‘cause economic gains made, have rapidly gone down the drain.
Milk and malt, sugar and salt, flower and flour all alike,
Boots and books, gas and glass, all slapped with VAT.
Zero the VAT, free the sales, grow the base and lessen the burden, so that the common man may live.

Make them buy the little they buy, for by the way, multitudes are tiranny of numbers of sorts, and grow the little wider cake that is sought for, by all.
Otherwise, stiffle the sales by the common man and face the music of capital flight and fight for relevance, already thrown out of the window.

Taxable is not all, so exempt one or two,
If you so much care, as you claim you do.
Are we duped or dopped all the same, for a struggling folks eking life?
No matter the matter, Mater hospitals the mother, and all is sick and depressed in the depression.

Rich and paupers all alike, the common denominator, is the grave.
Hurt not the gas, the flour, the oil and all, for the sake of all.
When the present percentage is passed, ill-timed evil will lurk, to the chagrins and the detriment of all, and not just a few,
So then, VAT is that!.

Background:
Marine invertebrates rely solely on innate immune mechanisms, the cellular component of which is characterized by hemocytes that phagocytize microbes and secrete soluble antimicrobial and cytotoxic substances. In this regard, marine invertebrates are a potential source of promising antimicrobial compounds with novel mechanisms of action.
Objective:
The objective of this study was to evaluate extracts of the gut, gonad, spines and mouth parts of the sea urchin Tripneustes gratilla for antimicrobial and haemolytic activities in vitro.
Methods:
Potentially bioactive metabolites were extracted using methanol and chloroform and tested for activity against Salmonella typhi, Escherichia coli, Shigella sonnei, Pseudomonas aeruginosa and Penicillium spp. using the agar disc diffusion method. Toxicity was determined by assaying for hemolysis against human red blood cells.
Results:
Bioactivity against the tested bacteria was observed mainly with the methanol and chloroform extracts of the gonads and gut. Higher antibacterial activity was present in the methanol extracts compared to chloroform extracts. Activity against the Penicillium spp was detected only in the methanol extracts, while the chloroform extracts showed no activity. The various extracts of the sea urchin lacked any detectable hemolytic activity against human erythrocytes.
Discussion:
These research findings suggest that marine echinoderms are a potential source of novel antimicrobial compounds.
Key words:
Tripneustes gratilla, antimicrobial activity, marine invertebrates

Rangeland condition and trend in Mashuru s. .DivIsion of Kajiado District in Kenya has been deteriorating in terms of grazing capacity due to degradation of vegetation resources. Therefore a research study was conducted in 2001/2 with the objective of analyzing the types of vegetation degradation, their causes and their influence on rangeland condition and trend. The results ofthe qualitative study showed that excessive use of the woody species by humans for woodfuel, building and fencing materials, medicine and ornamentals had led ,I I to vegetation degradation due to loss of cover, change in plant composition and biodiversity. On the other hand, overgrazing and ecological succession of the grazing ]ands had led to bush encroachment and thickening. These types of vegetation degradation have had an overall effect of loss of grass cover and hence loss of grazing capacity for livestock, especially cattle. The causes of vegetation decrease or increase over the last 30 years have been due to deforestation (trees and shrubs), bush encroachment and thickening, change in plant species composition and natural calamities such as droughts, wild fires and armyworm invasions at various times. The overall results indicated that there has been a downward trend in range condition over the last 30 years which had affected livestock productivity. There is need therefore, for concerted efforts to be made to reverse or halt further vegetation degradation in the area through the participation of the local people, governmental and non-governmental organizations presently involved in rehabilitation and conservation of vegetation resources in the area.

Separation of midgut membrane proteins from the tick, Ambylomma variegatum, using a nonionic detergent (Triton X-114), resulted in two protein fractions, namely DET (detergent) and AQ (aqueous). In immunoblotting analysis with polyclonal antibodies against these fractions, 4 proteins (Mr approximately 27,000, 67,000, 86,000 and 95,000,) and 2 proteins (M, approximately 54,000 and 67,000) were detected in the DET and AQ fractions, respectively. Three of the DET fraction proteins Mr approximately 27,000, 67,000 and 95,000 were glycosylated since they bound to the lectin, concanavalin A. In 2-dimensional gel electrophoresis, the AQ and DET fraction proteins were found to be acidic in nature. In a series of bioassay experiments, rabbits were first immunised with both DET and AQ fractions and then infested with ticks. The egg batch weights of these ticks were reduced by 50% compared to control ticks. Furthermore, there was a significant reduction in the hatchability of eggs laid by ticks fed on rabbits previously immunised with both DET (14%) and AQ (33%) fractions. Based on the egg hatchability, the reproductive capacity of ticks was reduced by 77 and 48% by DET and AQ fractions, respectively.

Ethnopharmacological relevance: Traditional medicines play an important role in the management of chronically painful and debilitating joint conditions, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully exploited. The present study was carried to find the medicinal plants traditionally used to manage chronic joint pains in Machakos and Makueni counties in Kenya. Materials and methods: To obtain this ethnobotanical information, 30 consenting traditional herbal med-ical practitioners were interviewed exclusively on medicinal plant use in the management of chronic joint pains, in a pre-planned workshop. Results and discussion: In this survey, a total of 37 plants belonging to 32 genera and 23 families were cited as being important for treatment of chronic joint pains. The most commonly cited plant species were Pavetta crassipes K. Schum, Strychnos henningsii Gilg., Carissa spinarum L., Fagaropsis hildebrandtii (Engl.) Milve-Redh. and Zanthoxylum chalybeum Engl. Acacia mellifera (Vahl) Benth., Amaranthus albus L., Balanites glabra Mildbr. & Schltr., Grewia fallax K. Schum., Lactuca capensis, Launaea cornuta (Oliv. & Hiern) O.

Frenea, J.; Bonneaua MD; S. "Velocity Measurements Grease – Lubricating Film of a Sliding Contact.". 2008. Abstract

Experimental results of the velocity distribution in a grease-lubricated cylindrical sliding contact are obtained. A comparison is made with the theoretical results of a parabolic velocity distribution similar to that of a Newtonian fluid, derived from a Bingham plastic flow model. This equation compares very well with the experimental results.

Aduda BO, Boccaccini AR. "Velocity of elastic waves in porous ceramic materials: influence of pore structure." British Ceramic Transactions. 2003;102(3):103-108. Abstract

A review of recently published ultrasonic velocity-porosity data on a variety of porous ceramic materials,
which included information on the pore structure, has been undertaken. These experimental data have been
compared with those calculated using a spheroidal pore model that incorporates information on pore volume
fraction, shape and orientation. Good agreement, especially when fractional porosity is less than ~ 0.25,
between the experimental and calculated values is obtained even when a single ‘effective’ pore shape is
employed in the calculation. The agreement improves if the pore shape at each particular porosity level (the
point-by-point analysis) is used. The predictive ability of the spheroidal pore model is therefore demonstrated.

{BACKGROUND/AIMS} Ventriculoperitoneal shunt complications have scarcely been reported in sub-Saharan Africa. This study aimed at determining the frequency of these complications and their associated risk factors in a Kenyan National Teaching and Referral Hospital. {METHODS} This cross-sectional study retrospectively covered 117 patients admitted to the Kenyatta National Hospital neurosurgical ward between January 2005 and December 2007 with ventriculoperitoneal shunt complications. The data obtained were analysed using the Statistical Package for the Social Sciences. {RESULTS} The most common complication was obstruction in 63 patients (53.8%), followed by migration in 25 (21.4%) and infection in 23 (19.7%) of the patients. Up to 49.6% of the complications occurred in patients younger than 6 months. Multiple complications were seen in 23.9% of the cases. The mean shunt duration was 18.05 months. Positive correlations existed between the presence of a shunt complication and patient age, shunt duration and the number of complications developed. These correlations were, however, neither strong nor statistically significant. {CONCLUSION} This study reports the highest frequencies of shunt obstruction and migration ever recorded in the literature. The high rate of development of multiple shunt failures coupled with a short shunt duration calls for a closer monitoring of patients with ventriculoperitoneal shunts.

Nimrod J, Omulo TOM. "Ventriculoperitoneal shunt surgery and shunt infections in children with non-tumour Hydrocephalus at the Kenyatta National Hospital, Nairobi.". 2000. Abstract

study infections complicating ventriculoperitoneal (VP) shunt surgery in children with non-tumour hydrocephalus at the Kenyatta National Hospital, Nairobi. DESIGN: A retrospective survey. SETTING: Kenyatta National Hospital, Nairobi between January 1982 and December 1991. SUBJECTS: Three hundred and forty five patients who underwent V-P shunt placement for non-tumour hydrocephalus. RESULTS: Three hundred and forty five patients underwent V-P shunt placement for non-tumour hydrocephalus. There were 107 infection episodes involving 85 patients. The ages of these patients ranged from three months to 12 years. Most of the patients had congenital hydrocephalus. The infection rate was high (24.6%) although comparable to infection rates reported for clean surgery in the hospital. Fever, septic wounds and features of shunt malfunction were the main presenting features. Bacteriological studies confirmed Staphylococcus aureus and coagulase negative staphylococci as the two most commonly isolated micro-organisms. CONCLUSION: This study emphasises need to reduce infection rate in ventriculoperitoneal shunt surgery at the Kenyatta National Hospital. Definitive surgical treatment for hydrocephalus was in most cases delayed and this problem was also observed during revision of infected shunts. Late presentation was often due to ignorance and the fact that many patients went for traditional forms of treatment first before going to hospital.

Verbal autopsy was used to determine causes of death in 239 children under the age of 5 years. The diagnosis derived from verbal autopsy was corroborated with hospital diagnosis in 39 cases. There was concurrence of diagnosis in 72% of the cases. Using the diagnosis of broncho pneumonia to validate the method, verbal autopsy was found to have a sensitivity of 71%, specificity of 92%, a positive predictive value of 85%. Reliability index of agreement was 0.654. Recall period up to 29 months after death was found to be reliable.

Ssozi, J; Akundabweni LSM; NA. Verifying the premium value of selected African indigenous vegetables in target sites of the Lake Victoria basin.; 2012. Abstract

The purpose of this research was to verify the premium value in terms of nutritional and economic potential of selected African indigenous vegetable plants (AIVPs) along the Lake Victoria basin. Partial findings of this study being reported are on the smallholder farmer indigenous knowledge of vegetable production and utilisation in Jinja (Uganda) and Vihiga (Kenya). A survey was conducted to establish the status and level of utilisation of indigenous vegetable plants. whereby total of 163 households in each site were interviewed. Vegetables selected by smallholder farmers for production trials and nutrient quality analysis were Cleome gyandra (Saga, Eiyobyo/Ejobyo), Amaranthus lividus (Booga, Doodo), Solanum scarbrum (nakati) as indigenous vegetables. Solanum melongena (egg plant), Daucus carota (carrot), Capsicum spp. (pepper) were selected as the exotic vegetables. Laboratory analysis of these vegetables for phyto-nutrient characterisation is ongoing. The survey revealed that most farmers (90%) engaged indigenous vegetable farming for both food consumption and income generation. Most farmers regarded exotic vegetable farming as an income generation venture rather than home consumption. Most farmers were knowledgeable of the health and medicinal benefits of the indigenous vegetables.

Six Topi (Damaliscus korrigum) from the Masai Mara area of Kenya were examined.  All had lungworm nodules. The nodules were generalized in distribution among the lung lobes.  These nodules were essentially hepatized lung tissue with adult worms, larvae and eggs with marked cellular reaction accompanying the infection. The cell types were mostly lymphocytes, plasma cells, macrophages, giant cells and eosinophils. The worms were identified as protostrongylus africanus.

Seventeen cows of various breeds with varying degrees of severity of advanced ocular squamous cell carcinoma were treated by radical surgery, which included enucleation and extirpation of the surrounding ocular muscles and tissues. The degree of severity and the extent of the carcinoma lesion was correlated with the outcome of treatment for each case. It was observed that: 1. eyeball involvement, 2. ulceration and subsequent infection of carcinoma lesion involving the eyelids and 3. involvement of the regional lymphnodes especially the parotid , are some of the main factors that could be used to draw prognosis of such cases. Although the initial surgery may not be costly, the overall cost of managing postoperative complications is prohibitive and results to vast economic losses that should not be ignored.

"A versatile hplc method for the simultaneous determination of bromhexine, guaifenesin, ambroxol, salbutamol/terbutaline, pseudoephedrine, triprolidine, and chlorpheniramine maleate in cough–cold syrups." Chromatographia . 2016;79(21):1507-1514. Abstract

A simple, rapid, isocratic, and versatile liquid chromatographic method was developed for the simultaneous
determination of bromhexine, guaifenesin, ambroxol, salbutamol/terbutaline, pseudoephedrine, triprolidine, and
chlorpheniramine maleate in cough–cold syrups commonly marketed in Kenya. Separation was achieved using
a Gemini® NX C18 column (250 × 4.6 mm, 5 μm) maintained at 40 °C and a mobile phase consisting of acetonitrile-0.25 M sodium hexanesulphonate-0.2 M ammonium acetate, and pH 3.0-water (35:4:10:51, % v/v/v/v) delivered at 1.0 mL min−1. The eluents were monitored by means of UV detection at 254 nm. During validation, the method satisfied the International Committee on Harmonization acceptance criteria for linearity, sensitivity, precision, accuracy, and robustness. The developed liquid chromatographic method was applied in the analysis of nine commercial samples obtained from Nairobi City County, Kenya. Extraction procedures were not applied during the assay of the samples, thus significantly shortening the analysis time.

In the past decades, anaerobic digestion (AD) has steadily gained importance. However, the technology is not regarded as a top priority in science policy and in industrial development at present. In order for AD to further develop, it is crucial that AD profits from the current fuel issues emerging in the international arena. AD can provide low-cost treatment of sewage and solid domestic wastes, which represents a vast application potential that should be promoted in the developing world. Furthermore, the developments in the last decades in the domain of anaerobic microbiology and technology have generated some interesting niches for the application of AD, such as anaerobic nitrogen removal and the treatment of chlorinated organics. Recently, AD has also generated some serendipities, such as the use of AD in processes for sulphur and calcium removal and the coupling of AD with microbial fuel cells. The international developments in terms of bio-refineries and CO2-emission abatement are of crucial importance with respect to the impetus that AD will receive in the coming decade. There should be little doubt that by placing the focus of AD on the production of green energy and clean nutrients, the future of AD will be assured. PMID: 16180409 [PubMed - indexed for MEDLINE
Ogeng’o J, Olabu B, Sinkeet R, Ogeng’o NM, Elbusaid H. "Vertebral Artery Hypoplasia in a Black Kenyan Population." Hindawi Publishing Corporation International Scholarly Research Notices. 2014;2014:5. AbstractVertebral Artery Hypoplasia in a Black Kenyan Population

Vertebral artery hypoplasia (VAH) refers to those arteries
with diameter of less than 2.0mm [1–3].This condition predisposes
to posterior circulation stroke [4–7] and vertebral
artery (VA) atherosclerosis [2, 8, 9] and can be confusedwith
pathological occlusion from, say, atherosclerosis or dissection
[10]. It is also associated deformities of other arterial components
of posterior circulation including basilar and posterior
communicating arteries [11, 12].Characteristics of this condition
are also important in selection andmoulding of catheters
during interventional neuroradiological procedures as well
as mitigating complications of endovascular treatment and
prognostication of cerebrovascular disease [11].
These characteristics of VAH show ethnic variation [13,
14]. As intracranial cerebral atherosclerosis becomes more
common in Sub-Saharan African countries [15], there is
need for data on African populations to informmanagement
of disorders in posterior circulation. There are, however,
currently few data from black African populations. This
study, therefore, investigated the pattern of vertebral artery
hypoplasia in an adult black population.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

A cross sectional study of 115 patients admitted at the Department of Orthopedics, Kenyatta National Hospital, Nairobi, Kenya was carried out to determine the prevalence and antibiotic susceptibility of Staphylococcus aureus isolated from infected wounds. The prevalence of Staphylococcus aureus was 33.0 %. The drugs tested and their corresponding sensitivity was amoxycillin (13.2 %), co-amoxyclav (39.5 %), oxacillin (55.3 %), erythromycin (44.7 %), gentamicin (60.5 %), ciprofloxacin (62.2 %), minocycline (86.8 %), cefuroxime (57.9 %), and clidamycin (84.2 %). These results show the sensitivity profile of Staphylococcus aureus and can be used to choose suitable drugs in the management of wounds for hospitalized patients.

Seroprevalence studies reveal that 90%-100% of the population acquires anti-HAV antibody and becomes immune by adolescence. Many epidemics of HEV have been reported from India. HAV related liver disease is uncommon in India and occurs mainly in children. HEV is also the major cause of sporadic adult acute viral hepatitis and ALF. Pregnant women and patients with CLD constitute the high risk groups to contract HEV infection, and HEV-induced mortality among them is substantial, which underlines the need for preventive measures for such groups. Children with HAV and HEV coinfection are prone to develop ALF. India has intermediate HBV endemicity, with a carrier frequency of 2%-4%. HBV is the major cause of CLD and HCC. Chronic HBV infection in India is acquired in childhood, presumably before 5 years of age, through horizontal transmission. Vertical transmission of HBV in India is considered to be infrequent. Inclusion of HBV vaccination in the expanded programme of immunization is essential to reduce the HBV carrier frequency and disease burden. HBV genotypes A and D are prevalent in India, which are similar to the HBV genotypes in the West. HCV infection in India has a population prevalence of around 1%, and occurs predominantly through transfusion and the use of unsterile glass syringes. HCV genotypes 3 and 2 are prevalent in 60%-80% of the population and they respond well to a combination of interferon and ribavirin. About 10%-15% of CLD and HCC are associated with HCV infection in India. HCV infection is also a major cause of post-transfusion hepatitis. HDV infection is infrequent in India and is present about 5%-10% of patients with HBV-related liver disease. HCC appears to be less common in India than would be expected from the prevalence rates of HBV and HCV. The high disease burden of viral hepatitis and related CLD in India, calls for the setting up of a hepatitis registry and formulation of government-supported prevention and control strategies.

"Viral linkage in HIV-1 seroconverters and their partners in an HIV-1 prevention clinical trial." PLoS ONE. 2011;6(3):e16986. Abstract

Characterization of viruses in HIV-1 transmission pairs will help identify biological determinants of infectiousness and evaluate candidate interventions to reduce transmission. Although HIV-1 sequencing is frequently used to substantiate linkage between newly HIV-1 infected individuals and their sexual partners in epidemiologic and forensic studies, viral sequencing is seldom applied in HIV-1 prevention trials. The Partners in Prevention HSV/HIV Transmission Study (ClinicalTrials.gov #NCT00194519) was a prospective randomized placebo-controlled trial that enrolled serodiscordant heterosexual couples to determine the efficacy of genital herpes suppression in reducing HIV-1 transmission; as part of the study analysis, HIV-1 sequences were examined for genetic linkage between seroconverters and their enrolled partners.

Ochieng W. "Viral load, CD4+ T-lymphocyte counts and antibody titres in HIV-1 infected untreated children in Kenya; implication for immunodeficiency and AIDS progression.". 2006. Abstract

ere are limited reports on HIV-1 RNA load, CD4+ T-lymphocytes and antibody responses in relation to disease progression in HIV-1 infected untreated children in Africa. METHODS: To describe the relationships between these parameters, we conducted a longitudinal cohort study involving 51 perinatally HIV-1 infected children aged between 1 and 13 years. HIV status was determined by ELISA and confirmed by western blot and PCR. Antibodies were quantified by limiting dilution ELISA, plasma HIV-1 RNA load by RT-PCR and CD4+ T-lymphocytes by FACSCount. RESULTS: Asymptomatic and symptomatic disease had, respectively, a rise in median HIV-1 RNA load from 1,195 to 132,543 and from 42,962 to 1,109,281 copies/ml in children below 6 years. The increase in viral load was 10-fold higher for asymptomatic compared to other categories and 2-fold faster for children less than 6 years than those above. Similarly, symptomatic children below 6 years had initial median CD4+ T-lymphocyte counts of 647 (22%) cells/muL, declining to 378 (20%) while those above 6 years had initial values of below 335 (15%) but which increased to 428 (17%). Median viral load correlated significantly with median CD4+ T-lymphocyte percentage in children above 6 years (p=0.026) but not below. CONCLUSIONS: Viral load is lower in older than younger children and correlates significantly with percentage CD4+ T-lymphocytes. Survival by HIV-1 infected children requires a competent immune response early in infection to counter the rapidly replicating virus. Interventions aimed at boosting the naïve immune system may prolong survival in these children.

BACKGROUND: The viral safety of blood depends on donor selection and screening of the blood for viruses. OBJECTIVE: To determine the frequency of human immunodeficiency viruses 1 and 2, hepatitis B virus and hepatitis C virus in a population of donors. DESIGN: Retrospective study including all blood donations at a hospital-based transfusion unit between January 1995 and August 1998. RESULTS: A significant declining trend in the frequency of the human immunodeficiency virus from 4.5% in 1995 to 3.0% in 1998 was noted. Hepatitis B virus (HBV) decreased from 4.2% in 1995 to 3.9% in 1998, while hepatitis C (HCV) increased from 1.5% in 1996 to 1.8% in 1998. The changes for both HBV and HCV were not statistically significant. CONCLUSION: The safety of blood and blood products with respect to HIV, HBV and HCV is very high. It is important to educate donors regarding transfusion transmitted infections. It is recommended that HCV screening be implemented as a standard test for all donations.

Abstract

Localization of Newcastle disease viral nucleoprotein and pathological lesions was evaluated in tissues of 55 indigenous ducks (45 experimentally infected and 10 sentinel ones). In addition, ten Newcastle disease infected chickens were used to ensure that the virus inoculum administered to the ducks produced the disease in chickens, the susceptible hosts.
Ducks were killed on day 1, 4, 8 and 14 post-infection. Post mortem examination was done with six tissues (liver, spleen, lung, caecal tonsils, kidneys and brain) being collected from
each bird. The tissues were preserved in 10% neutral formalin for 24 h. They were then transferred to 70% ethanol for histology and immunohistochemical staining. Airsacculitis,
necrotic splenic foci, congested intestines, lymphoid depleted caecal tonsils and focal infiltrations by mononuclear cells were the main pathological lesions in infected ducks. Over 28.9% of the infected ducks had Newcastle disease viral nucleoprotein in macrophage-like large mononuclear cells in the caecal tonsils and kidney tubular epithelium. The viral antigens were located in the cytoplasm and nucleolus of the cells. The other organs had no detectable viral antigens. This study shows that the kidneys and caecal tonsils are the likely predilection sites for the virus in ducks. They thus need to be considered as diagnostic indicators for the viral carriage in ducks.

BACKGROUND: Understanding shedding patterns of 2009 pandemic influenza A (H1N1) (pH1N1) can inform recommendations about infection control measures. We evaluated the duration of pH1N1 virus shedding in patients in Nairobi, Kenya. METHODS: Nasopharyngeal (NP) and oropharyngeal (OP) specimens were collected from consenting laboratory-confirmed pH1N1 cases every 2 days during October 14-November 25, 2009, and tested at the Centers for Diseases Control and Prevention-Kenya by real time reverse transcriptase polymerase chain reaction (rRT-PCR). A subset of rRT-PCR-positive samples was cultured. RESULTS: Of 285 NP/OP specimens from patients with acute respiratory illness, 140 (49%) tested positive for pH1N1 by rRT-PCR; 106 (76%) patients consented and were enrolled. The median age was 6 years (Range: 4 months-41 years); only two patients, both asthmatic, received oseltamivir. The median duration of pH1N1 detection after illness onset was 8 days (95% CI: 7-10 days) for rRT-PCR and 3 days (Range: 0-13 days) for viral isolation. Viable pH1N1 virus was isolated from 132/162 (81%) of rRT-PCR-positive specimens, which included 118/125 (94%) rRT-PCR-positive specimens collected on day 0-7 after symptoms onset. Viral RNA was detectable in 18 (17%) and virus isolated in 7/18 (39%) of specimens collected from patients after all their symptoms had resolved. CONCLUSIONS: In this cohort, pH1N1 was detected by rRT-PCR for a median of 8 days. There was a strong correlation between rRT-PCR results and virus isolation in the first week of illness. In some patients, pH1N1 virus was detectable after all their symptoms had resolved.

The outbreak of COVID-19 pandemic saw overwhelming effects on consumers’ buying behavior globally, with economic productive activities shifting from offline to online. As a result, many business leaders were left with no option other than adopt the use of Information Technology to ensure business operations continuity, enhance efficiency as well as sustainability. In Kenya, unlike most commercial banks, Saccos have largely been left behind in embracing new banking technologies such as agency banking, internet banking, or mobile banking. Therefore, the use of paperwork, physical and in-person meetings to conduct business has remained widespread amongst many Saccos in the country, before COVID 19 that forced Saccos to shift to virtual banking as an effective alternative, toward addressing their customers’ needs while ensuring safety. This study examined the adoption of Mobile Banking models and Virtual Banking technologies and innovations to establish the factors influencing their adoption by potential users. The study also explored the adoption of Virtual banking amongst Saccos in Kenya, investigating the electronic delivery channels used, and their suitability. The study objectives were accomplished through an exploratory and descriptive approach based on ways of improving access to credit through relationships between Sacco and their clientele in Kenya through the adoption of Virtual Banking. The data used was collected from SACCO-based respondents who included Sacco ICT officers, managers, and members using questionnaires. Data analysis was done using the Statistical Package for Social Sciences (SPSS). The study established that there was wide adoption of various Mobile Banking models and technologies to realize virtual banking adoption by Saccos. Most Saccos were found to favor the Joint venture model and the non-bank-driven model. The extent of adoption of virtual banking amongst bank clientele was found to be influenced by social, economic, and technological factors. The study recommended that Saccos should consider sharing information and technologies across various networks as this is likely to lead to much more gains in adopting technologies that would improve their sustainability as while fostering better customer experience.

Burkitt lymphoma (BL) is an aggressive neoplasm characterized by consistent morphology and phenotype, typical clinical behavior and distinctive molecular profile. The latter is mostly driven by the MYC over-expression associated with the characteristic translocation (8;14) (q24; q32) or with variant lesions. Additional genetic events can contribute to Burkitt Lymphoma pathobiology and retain clinical significance. A pathogenetic role for Epstein-Barr virus infection in Burkitt lymphomagenesis has been suggested; however, the exact function of the virus is largely unknown.In this study, we investigated the molecular profiles (genes and microRNAs) of Epstein-Barr virus-positive and -negative BL, to identify specific patterns relying on the differential expression and role of Epstein-Barr virus-encoded microRNAs.First, we found significant differences in the expression of viral microRNAs and in selected target genes. Among others, we identified LIN28B, CGNL1, GCET2, MRAS, PLCD4, SEL1L, SXX1, and the tyrosine kinases encoding STK10/STK33, all provided with potential pathogenetic significance. GCET2, also validated by immunohistochemistry, appeared to be a useful marker for distinguishing EBV-positive and EBV-negative cases. Further, we provided solid evidences that the EBV-encoded microRNAs (e.g. BART6) significantly mold the transcriptional landscape of Burkitt Lymphoma clones.In conclusion, our data indicated significant differences in the transcriptional profiles of EBV-positive and EBV-negative BL and highlight the role of virus encoded miRNA.

OBJECTIVE: In sub-Saharan Africa, many family planning programmes do not encourage advance provision of oral contraceptives to clients who must wait until menses to initiate pill use. Since some resistance to advance provision of pills is due to provider fears that the practice may be harmful, we conducted a study in Kenya in 1997 to compare pill-taking outcomes between 20 "advance provision" clients and 280 "standard" clients. DESIGN: Prospective observational study. SETTING: Six family planning clinics in Central and Western Kenya. SUBJECTS: Women presenting as new clients at MOH family planning clinics. INTERVENTIONS: Researchers used prospective tracking to compare indicators of pill-taking success between non-menstruating clients given pills to carry home for later use and menstruating clients who began pill use immediately. MAIN OUTCOME MEASURES: Pill-taking outcomes such as side effects, compliance, knowledge, satisfaction, and a continuation proxy. RESULTS: Among clients returning for re-supply, those receiving advance provision of pills did no worse than, and often had superior outcomes to, their counterparts who started taking pills immediately after the clinic visit. CONCLUSIONS: Advance provision of pills, already practiced worldwide, is safe and feasible. Explicit mention should be made of advance provision of pills in national family planning guidance documents and training curricula in Kenya and throughout sub-Saharan Africa.
Gicheru MM, Olobo JO, Kariuki TM, Adhiambo C. "Visceral leishmaniasis in vervet monkeys: immunological responses during asymptomatic infections." Scand. J. Immunol.. 1995;41(2):202-8. Abstract

Nine vervet monkeys (Cercopithecus aethiops) were infected intradermally with 8 x 10(7) virulent L. donovani promastigotes. Four animals developed clinical visceral leishmaniasis and died over a period of 18 months. The remaining five animals have remained asymptomatic for a period of 3 years now. Attempts to isolate parasites from spleen and liver through biopsies were fruitless. Immunological responses of these subclinically infected animals were examined. Enzyme-linked immunosorbent assay (ELISA) and western blot analyses demonstrated Leishmania specific antibodies in these animals, but the antibody titres were low. When proliferation of peripheral blood monocytes (PBMC) to Concanavalin A (Con A) of these animals was compared with control 'disease free animals' there were no significant differences in response. However, L. donovani antigen (fixed promastigotes) specific proliferation was demonstrated in the five subclinically infected animals. High and varying levels of interferon gamma (IFN-gamma) were secreted in PBMC cultures from the five vervet monkeys when stimulated with either Con A or L. donovani antigens. In control animals, IFN-gamma was only detected when PBMC were stimulated with Con A. Marked delayed-type hypersensitivity (DTH) responses were demonstrated in the five subclinically infected animals 48 h after injection with formalin fixed promastgotes. It was concluded that the visceral Leishmania disease spectrum due to L. donovani observed in humans could be induced in vervet monkeys and that L. donovani asymptomatic/cryptic infected animals have competent humoral and cellular responses to homologous parasites.

Department of Veterinary Medicine, Faculty of Veterinary Medicine, Makerere University, Kampala, Uganda. Pulmonary oedema is a common sign of East Coast fever (ECF, Theileria parva infection) of cattle. A trial was conducted on farms in Uganda to compare a product containing both the antitheilerial compound parvaquone and the diuretic compound frusemide with one containing only parvaquone, in the treatment of ECF. The trial involved 40 clinical cases of ECF, some of them complicated by other infections, in cattle of all ages and on several farms. Confirmed cases were treated with either parvaquone+frusemide (P+F) or parvaquone alone (P). Survival after treatment with P+F was 77% compared with 71% with P. Five of the 10 fatalities were complicated cases. The cure rate for severe but uncomplicated ECF was 89% with P+F and 40% with P. Pulmonary signs were resolved within 24-48 h after treatment with P+F and clinical recovery was noticeably more rapid than with P. The antiparasitic effect of the two treatments was similar. P+F could be particularly useful when reporting, diagnosis or laboratory confirmation of ECF is delayed, because advanced cases are more likely to be encountered under these circumstances.

Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. 81, 276-281]. The protein (lectin-trypsin complex) was found to be capable of stimulating differentiation of bloodstream trypanosomes in vitro. Using polyclonal antibodies to the complex, we screened a G. fuscipes fuscipes cDNA midgut expression library and identified a putative proteolytic lectin gene. The cDNA encodes a putative mature polypeptide with 274 amino acids (designated Glossina proteolytic lectin, Gpl). The deduced amino acid sequence includes a hydrophobic signal peptide and a highly conserved N-terminal sequence motif. The typical features of serine protease trypsin family of proteins found in the sequence include the His/Asp/Ser active site triad with the conserved residues surrounding it, three pairs of cysteine residues for disulfide bridges and an aspartate residue at the specificity pocket. Expression of the gene in a bacterial expression system yielded a protein (M(r) approximately 32,500). The recombinant protein (Gpl) bound d(+) glucosamine and agglutinated bloodstream-form trypanosomes and rabbit red blood cells. In addition, the protein was found to be capable of inducing transformation of bloodstream-form trypanosomes into procyclic forms in vitro. Antibodies raised against the recombinant protein showed cross-reactivity with the alpha subunit of the lectin-trypsin complex. These results support our earlier hypothesis that this molecule is involved in the establishment of trypanosome infections in tsetse flies.

The groundnut, Arachis hypogaea Linn, samples were collected from the majorly grown areas of western Kenya to investigate the viscoelastic properties pertinent to grain handling, storage and processing. In particular, the study conducted at the University of Nairobi, Department of Environmental and Biosystems laboratories in July 2010, aimed at investigating the stress-strain properties of bulk groundnuts in relation to Maxwell polymer viscoelastic model. The Mohr-Coulomb failure criterion was also applied to bulk groundnuts. Three samples were prepared for triaxial tests; each weighing 1062.4 g. The moisture content of the samples was 7.6%. The sample size for triaxial testing was 100 mm diameter and 199 mm height. Density of the samples during the tests was 678.6 kg/m3. Confining stresses of 200, 400 and 600 kPa were used and Axial Strain Rate (ASR) of 0.5 mm/min was used for the triaxial compression tests. For the senstar universal testing machine relaxation time was about 30 min for each of the samples. Relaxation data was recorded after every 30 sec for the duration of the test (30 min). These results showed that the Maxwell model for viscoelastic polymers can be applied to accurately describe the behaviour of bulk groundnuts.

Day S. "Vision development in the monocular individual: implications for the mechanisms of normal binocular vision development and the treatment of infantile esotropia." Transactions of the American Ophthalmological Society. 1995;93:523-581. AbstractWebsite

PURPOSE: The purpose of this research is to study the vision development in monocular individuals so as to better understand normal binocular vision development and to refine the treatment of infants with infantile esotropia. METHODS: Thirty-six subjects with one clinically normal eye and one eye with no vision (no light perception or history of enucleation) are studied. In addition to measurement of standard parameters of development such as visual acuity, measurement of motion processing is made by both optokinetic and electrophysiologic techniques. A comparison is made of vision development among three populations: the monocular population, the normal population, and patients with a history of infantile esotropia. Such comparison is made to study the relative effects of interruption of binocularity and binocular competition. The monocular population represents individuals who have interruption of binocularity, whereas the infantile esotropia population has both interruption of binocularity and binocular competition. RESULTS: The OKN data suggest that the monucular population is more similar to the normal population than the esotropia population. The electrophysiologic data shows a statistically significant difference in the three populations. Motion processing is more fully developed in the monocular population than in the infantile esotropia population when compared to the normal population. CONCLUSIONS: 1. The development of motion processing appears to be particularly vulnerable to abnormal experience during the first year of life. 2. Monocular subjects have a less abnormal motion processing system when compared to patients with infantile esotropia even when monocularity is congenital. 3. The results indirectly support the premise that prealignment alternate occlusion is of benefit to the patient with infantile esotropia prior to realignment. 4. Development of the motion processing system does not necessarily parallel the development of other binocular functions.

Objectives: To assess the vision of PSV drivers operating in Nairobi city and to establish whether poor sight is associated with the occurrence of motor vehicle accidents.
Design: Cross-sectional study
Setting: Nairobi city bus and matatu (small vans and minibuses) terminuses.
Subjects: 539 randomly selected PSV drivers.
Results: Sixty eight percent of the drivers did not have their sight checked during driving test. Drivers with inadequate vision were more frequently involved in accidents than those with adequate vision but difference was not statistically significant (p=0.76). Drivers with cataracts were 3 times more likely to be involved in accidents than those without (p=0.007).
Conclusions: Majority of PSV drivers do not undergo visual acuity testing before acquiring driving licenses.
Recommendation: Visual acuity testing should be made mandatory when applying for and renewing driving licenses.

Maurer D, Lewis TL. "Visual acuity: the role of visual input in inducing postnatal change." Clinical Neuroscience Research. 2001;1:239-247. AbstractWebsite

Some crude visual abilities are present at birth, and hence, do not depend on visual experience. However, there are substantial and rapid postnatal improvements. For example, the acuity of newborns is 40 times worse than that of normal adults, largely because of retinal immaturities. Between birth and 6 months of age, there is a five-fold increase in acuity, followed by slow improvement to adult levels by 6 years of age. This review examines the role of visual experience in inducing those improvements by comparing the visual development of normal children with that of children treated for congenital cataracts that blocked patterned visual input until the cataracts were removed surgically and the eyes were given a compensatory optical correction. The acuity of children treated for congenital cataracts does not improve before they receive patterned visual input, but then increases rapidly to reach normal limits by 1 year of age. However, the patients later show permanent deficits in acuity, presumably because the initial deprivation caused damage to the visual cortex. Studies of children who developed cataracts after birth indicate that visual input is also necessary to consolidate cortical connections. Moreover, the deleterious effects of visual deprivation are worse if there was also uneven competition between the eyes — because the deprivation was monocular and there was little patching of the non-deprived eye — but only at some points during development. Thus, the development of visual acuity is shaped by experience-dependent and competitive mechanisms that have different temporal parameters.

Tian N. "Visual experience and maturation of retinal synaptic pathways." Vision research. 2004;44:3307-3316. Abstract

The retinal synaptic network continues its maturational refinement after eye opening in mammals. This synaptic refinement is reflected in changes of retinal neuron synaptic activity and connectivity. In mature retina, the dendrites of retinal ganglion cells (RGCs) in the inner plexiform layer (IPL) of retina are separated into ON or OFF sublamina. At early developmental stage, however, the dendrites of most RGCs are ramified throughout the IPL. Recently we found that the postnatal maturational processes converting bistratified ON-OFF responsive RGCs to monostratified ON and OFF responsive RGCs depend upon visual stimulation after eye opening.

At early developmental stage, however, the dendrites of most RGCs are ramified throughout the IPL. Recently we found that the postnatal maturational processes converting bistratified ON–OFF responsive RGCs to monostratified ON and OFF responsive RGCs depend upon visual stimulation after eye opening.

Objectives: To determine the prevalence and pattern of ocular manifestations in adults
with intracranial neoplasms.
Design: Cross sectional hospital based study
Settings: Neurosurgical Clinic and Ward of Kenyatta National Hospital (KNH) from November 2005 to January 2006.
Subjects: 60 adult with intracranial neoplasm (32 females and 28 males)
Results: 31(52%) of the studied patients had not had any previous eye examination. Ocular symptoms were reported in 44 (73%) patients. 38 (63%) had colour vision defects, 20 (33%) papilloedema, 16 (27%) bilateral optic disc atrophy, 16 (27%) defective extra-ocular motility, 11(18%) bilaterally blind, 10 (17%) nystagmus, 6 (10%) proptosis and 4 (7%) diplopia. Only 11 (18%) of the patients had normal visual field. 40 (67%) were booked for routine follow-up at the Kenyatta Eye Clinic while 9 (15%) were referred for Low Vision Assessment. All the 11 (18%) blind patients were referred for rehabilitation.
Conclusion: Majority (73%) of patients attending the KNH Neurosurgical Clinic and those admitted in Neurosurgical ward have ocular involvement and visual loss. Colour vision defects were the commonest manifestations while total blindness was the most serious complication.
Recommendation: Neurosurgeons and ophthalmologists should work together as a team to ensure timely and comprehensive assessment and management of all patients with intracranial tumours both pre-operative and post-operatively. Stable patients with irreversibly visual impairment and blindness should be referred for Low vision therapy and rehabilitation.

Feller MB. "Visual system plasticity begins in the retina." Neuron. 2003;39:3-4. Abstract

Visual experience is known to induce developmental plasticity in visual cortex; now, Tian and Copenhagen report that experience regulates the development of retinal circuitry itself. Both pruning of retinal ganglion dendrites into ON or OFF sublamina and the emergence of pure ON versus OFF responses require visual experience.

Visual deprivation impedes refinement of neuronal function in higher visual centers of mammals. It is often assumed that visual deprivation has minimal effect, if any, on neuronal function in retina. Here we report that dark rearing reduces the light-evoked responsiveness of inner retinal neurons in young mice. We also find that 1 to 2 weeks after eye opening, there is a surge ({\textgreater}4-fold) in the frequency of spontaneous excitatory and inhibitory synaptic events in ganglion cells. Dark rearing reversibly suppresses this surge, but recovery takes {\textgreater}6 days. Frequency changes are not accompanied by amplitude changes, indicating that synaptic reorganization is likely to be presynaptic. These findings indicate there is a degree of activity-dependent plasticity in the mammalian retina that has not been previously described.

The development of the visual system is the most studied of the sensory systems. The advances in technology have made it possible to study the neuroprocesses at the cellular and circuit level. The physical structure of the eye develops early in fetal life, whereas the neurocomponents and connections develop in later fetal and early neonatal life. The development of the visual system involves genetic coding, endogenous brain activity, exogenous visual stimulation after birth at term, and protected sleep cycles, particularly rapid eye movement sleep. Before birth at term, the fetus requires no outside visual stimulation or light. The critical element in development of the visual system before birth at term is protection of rapid eye movement sleep and sleep cycles. Sleep deprivation or disruption in utero and early months of neonatal life causes significant interference with visual development resulting in loss of the topographic relationships between the retina, the lateral geniculate nucleus, and the primary visual cortex in the infant.

Tian N, Copenhagen DR. "Visual {Stimulation} {Is} {Required} for {Refinement} of {ON} and {OFF} {Pathways} in {Postnatal} {Retina}." Neuron. 2003;39:85-96. AbstractWebsite

ON and OFF pathways separately relay increment and decrement luminance signals from retinal bipolar cells to cortex. ON-OFF retinal ganglion cells (RGCs) are activated via synaptic inputs onto bistratified dendrites localized in the ON and OFF regions of the inner plexiform layer. Postnatal maturational processes convert bistratifying ON-OFF RGCs to monostratifying ON and OFF RGCs. Although visual deprivation influences refinement of higher visual centers, no previous studies suggest that light regulates either the development of the visual-evoked signaling in retinal ON and OFF pathways, nor pruning of bistratified RGC dendrites. We find that dark rearing blocks both the maturational loss of ON-OFF responsive RGCs and the pruning of dendrites. Thus, in retina, there is a previously unrecognized, pathway-specific maturation that is profoundly affected by visual deprivation.

Asian Economic and Social Society; 2001. Abstract
Background. The host immune response against mucosally-acquired pathogens may be influenced by the mucosal immune milieu during acquisition. Since Neisseria gonorrhoeae can impair dendritic cell and T cell immune function, we hypothesized that co-infection during HIV acquisition would impair subsequent systemic T-cell responses.   Methods. Monthly screening for sexually transmitted infections (STIs) was performed in high risk, HIV seronegative Kenyan female sex workers as part of an HIV prevention trial. Early HIV-specific CD8+ T cell responses and subsequent HIV viral load set point were assayed in participants acquiring HIV, and were correlated with the presence of prior genital infections during HIV acquisition.   Results. Thirty-five participants acquired HIV during follow up, and 16/35 (46%) had a classical STI at the time of acquisition. N. gonorrhoeae co-infection was present during HIV acquisition in 6/35 (17%), and was associated with an increased breadth and magnitude of systemic HIV-specific CD8+ T-cell responses, using both interferon- (IFNg) and MIP-1 beta (MIP1b) as an output. No other genital infections were associated with differences in HIV-specific CD8+ T cell response, and neither N. gonorrhoeae nor other genital infections were associated with differences in HIV plasma viral load at set point.   Conclusion. Unexpectedly, genital N. gonorrhoeae infection during heterosexual HIV acquisition was associated with substantially enhanced HIV-specific CD8+ T-cell responses, although not with differences in HIV viral load set point. This may have implications for the development of mucosal HIV vaccines and adjuvants.

Results of four years' studies from a number of hospitals in Kenya have shown that nosocomial infections in burns units are due to Methicillin Resistant Staphylococcus aureus (MRSA). Through chromosomal DNA and plasmid DNA, the stain is highly resistant to sulphonamide ointment and other antibiotics. 90% of patients admitted in burns units get colonized or infected with MRSA. The strain prolongs the duration of patients in hospitals. The burns degenerate to second and third degree burns, thereby necessitating skin grafting. The environment has been found to be contaminated with this strain with some staff members having chronic throat infections. Minocycline was found to be effective in treating the infected staff members. Cleaning this environment with Sodium dichloroisocyanurate (precepts)/Sodium hypochlorite (JIK) reduced drastically the mechanical transmission of bacteria in the units. The duration of stay of the patient was reduced. This shows that MRSA which is spread in government and private hospitals can cheaply be controlled by the proper use of disinfectants, antiseptics, and use of effective antibiotics when necessary.
