Despite the diverse conservative and surgical modalities for the management of temporomandibular joint (TMJ) dislocation and the controversy that surrounds them, very little has been done within the East-African setup in terms of highlighting and provoking greater interest in the epidemiology and management of TMJ dislocation. OBJECTIVE: To audit the pattern of occurrence, demographics, aetiology and enumerate the treatment modalities of TMJ dislocation at the oral and maxillofacial surgery division (OMFS) of the University of Nairobi Dental Hospital. DESIGN: Descriptive cross-sectional study. SETTING: University of Nairobi Dental Hospital (UNDH) from January 1995 to July 2005. RESULTS: Twenty nine patients had been diagnosed and managed for TMJ dislocation. Twenty (69%) were females and nine (31%) were males. Their ages ranged from 10-95 years with a mean of 42 years. The cases managed were primarily chronic in nature. The most common form being anterior TMJ dislocation, accounting for twenty-five (86.2%) cases. Trauma was implicated as an aetiology in only five (17%) of the cases while the remaining majority of twenty four (83%) cases were spontaneous. Amongst the causes of spontaneous TMJ dislocation, yawning was the most common accounting for fourteen cases (48.3%). Dislocations caused by trauma were found to be 12.6 times more likely to be associated with other injuries than spontaneous dislocations. Anterior TMJ dislocations were found to be 1.3 times more likely to be associated with absence of molars than posterior TMJ dislocations. Anatomical aberrations, as predisposing factors, were not a significant finding in this research. Eight (28%) of the cases were managed conservatively. Twenty one (72%) of the cases were managed surgically. The eminectomy was the most common technique with a 75% success rate. The highest incidence of TMJ dislocation occurs in the 3rd-5th decade with a female preponderance with bilateral anterior TMJ dislocation being the most common. Most of the cases were managed surgically with eminectomy being the preferred technique with the highest success rate. A study needs to be undertaken to determine reasons' why conservative modalities are least employed in the management of TMJ dislocation in our setup and what can be done about it.

Muriiithi, M, Mwango GN.  2010.  Wandering spleen: case report. Abstract

Wandering spleens are rare clinical entities found more commonly in women aged 20-40 years. We report one such case found in a 24-year-old nulliparous woman who presented with low abdominal pains of sudden onset and splenomegaly. An emergency abdominal CT scan showed an enlarged spleen located in the right lumbar region and extending into the pelvis. There was a long splenic pedicle containing tortuous vessels. A review of literature and the postulated aetiological factors and associations are discussed.

Pediatr Infect Dis J. 1989 Oct;8(10):700-4.. : Plant Molecular Biology Reporter Vol. 27, pp. 79-85. Abstract
A malformation syndrome has been proposed in infants with acquired immunodeficiency syndrome or acquired immunodeficiency syndrome-related complex secondary to congenital infection with human immunodeficiency virus (HIV) in the United States and Europe. To determine whether embryopathy is detectable in HIV-exposed African infants, 85 infants of HIV-seropositive mothers and 98 infants of HIV-seronegative mothers in Nairobi, Kenya, were examined for minor and major anomalous features shortly after birth. No mother used intravenous drugs. With the exception of growth failure no anomalous feature was associated with in utero HIV exposure. No increase in the number of anomalous features per infant was correlated with HIV, nor did any infant have the reported malformation syndrome. Thus in this population of African infants examination for anomalous features during the neonatal period failed to identify those infants with fetal exposure to HIV.
