W., GS, F.G. M, M. OT, A. WK.  2011.  Combined Modality Approach in the management of Oral and Circumoral Haemangiomas with emphasis on the use of Absolute Ethyl Alcohol.. AbstractWebsite

Although various modalities of treatment of haemangiomas including embolic therapy have been proposed, consideration of cost and technological requirements suggest that cheaper methods with less technological re-quirements need to be developed for use particularly in developing countries. The study objective was to de¬scribe the pattern of circumoral haemangiomas and explore the possible role of absolute ethyl alcohol in their management. It was a prospective study using hospital based study group at the University of Nairobi teaching and referral Dental Hospital. Of the 25 cases (24 females, 1 male) on follow-up, 68% had carvemous while 20% had capillary haemangiomas. The majority of the haem angiomas ranged in size from 2cm 2 - 31.5cm2. The lower lip was the most frequently affected (52%). None of the cases underwent spontaneous involution even after 10 years of follow-up. After intra lesions administration of alcohol, 3 cases of carvenous haeman¬gioma measuring 2cm2 and none of the capillary type underwent complete resolution. Other benefits of ethyl alcohol included better localization of the lesion and negligible intra and post operative haemorrhage for cases requiring surgery. Although pain and swelling for a few days were recorded in all cases and superficial tissue necrosis in two cases, there were no major alcohol-related complications. Therefore, Intra-lesion administra¬tion of absolute ethyl alcohol appears to be effective adjuvant to surgery and in addition may result in com¬plete resolution of small cavernous types of lesion. Spontaneous resolution of haemangiomas is not common in our set-up.

OBJECTIVE: To determine the pattern and characteristics of patients admitted with firearm injuries (FAIs) and establish the morbidity and mortality associated with these injuries. DESIGN: Retrospective cross-sectional study. SETTING: Kenyatta National Hospital (KNH), January 2004 to December 2005. SUBJECTS: All patients admitted with physically evident firearm injury. RESULTS: There were a total of 717 patients recorded with FAIs constituting 0.6% of the total number of patients seen in the casualty. Of these, 421 (58.7%) were admitted and treated as in- patients. A firearm was used in 6.7% of the 6300 assault cases recorded in 2004 and in 9.7% of the 3079 cases recorded in 2005. The increase from 6.7% in 2004 to 9.7% in 2005 was statistically significant (p < 0.05). There were 370 (87.9%) males and 49 (11.6%) females giving a male to female ratio of 7.5:1. The mean age was 29.7 +/- 10.9 years with a range of 3 to 66 years. At least 262 (62.2%) of the 421 admitted FAI casualties were treated under general anaesthesia (GA). The average duration of operation per patient was 2 +/- 1.5 hours. CONCLUSION: FAIs are on the increase and affect all age groups but is largely a disease of a young male adult in the 3rd and 4th decade of life. Mortality is higher with increasing age while female victims are fewer but on average six years younger than males. The lower extremities are the commonest target among the survivors. However, abdominal wounds tend to be the most lethal, accounting for greater mortality.

BACKGROUND: Road Traffic Accidents (RTAs) are a major cause of morbidity and mortality in Kenya. Victims may suffer multiple injuries including maxillofacial injuries. In most developing countries RTAs are the leading cause of maxillofacial injuries. In an attempt to reduce RTAs, the government of Kenya has enacted a legislation requiring mandatory fitting of speed governors and safety belts by passenger service vehicles. OBJECTIVE: To describe the characteristics and pattern of maxillofacial and associated injuries sustained in road traffic accidents. DESIGN: A cross-sectional study. SETTING: Kenyatta National Hospital (KNH). SUBJECTS: All patients involved in RTAs brought to casualty and the dental department of KNH as well as accident victims admitted to the KNH mortuary over a four- month period from September 2004 to December 2004. RESULTS: Four hundred and thirteen (85.7%) had non-fatal injuries whereas 69 (14.3%) had sustained fatal injuries. Males in the 21-30-year age group were the most affected. Most accidents occurred during weekends with pedestrians being the leading casualties in 59.5% and 71.4% of non-fatal and fatal cases respectively. Most accidents were caused by passenger service vehicles (matatus) which were responsible for 62% and 40.6% of non-fatal and fatal injuries respectively. Non-use of safety belts was reported in 56.6% of the cases who suffered non-fatal injuries. In the non-fatal category 89.6% of the casualties had soft tissue injuries (STIs) involving the craniofacial region with facial cuts being the majority (69.2%). Two hundred and seventy three (66.1%) incidents of other STIs than those of the head region were noted, the lower limbs accounting for 45.4% of these. Only 5.1% of the casualties with non-fatal injuries had fractures involving the maxillofacial skeleton. Skeletal injuries other than those involving the maxillofacial region were found in 142 (34.1%) incidents. In the fatal category head injury alone was the leading cause of death accounting for 37.7% of the cases followed by head and chest injuries combined which were responsible for 13% of the cases. CONCLUSION: Injuries to the maxillofacial skeleton appear to be uncommon in this series. Pedestrians in their third decade of life are most affected with passenger service vehicles being responsible in the majority of the cases. RECOMMENDATIONS: Interventional programmes targeting pedestrians and those in the third and fourth decades of life should be enacted.

OBJECTIVE: To determine the range of ablative surgery and rehabilitative procedures performed on maxillofacial structures. DESIGN: A retrospective descriptive study. SETTING: University of Nairobi Dental Teaching Hospital. SUBJECTS: Patients operated on at the institutions theatre, and followed up at the University of Nairobi Dental Teaching Hospital Oral Surgery Outpatient Clinic during the period February 1996, August 1998. RESULTS: Forty four patients underwent ablative surgery during the study period. Complete records were available for 38 patients, 27 females and 11 males aged 10 to 79 years (mean 32.6 years). Surgical procedures performed included: partial mandibulectomy, marginal mandibular resection, subtotal maxillectomy, sequestrectomy and enucleation. Six (15.8%) patients who underwent mandibular resection had rigid bone plating. Five (13.2%) patients who had maxillary involvement were given surgical obturators post-operatively with one receiving a complete denture after full recovery. A total of 22 (57.9%) patients who would have reaped benefits from prostheses therapy received none. Individual patient follow-up periods ranged from seven days for two patients who had cyst enucleation to two years for three cases with ameloblastoma, and two cases with squamous cell carcinoma. CONCLUSION: It is concluded that prosthetic rehabilitation of patients undergoing extensive surgery at the University of Nairobi Dental Teaching Hospital is largely inadequate.
