Orbital compression syndrome in a Ugandan child with sickle cell disease: A case report.

Orbital compression syndrome is a rare acute complication of sickle cell disease that may impair vision. Assessment by a multidisciplinary team incorporates detailed history and physical examination, fundoscopy, and appropriate imaging to exclude infections or neoplasms. Supportive treatment is adequate unless there is evidence of life-threatening space-occupying lesion warranting surgery.

Prevalence and associated factors of attention deficit hyperactivity disorder (ADHD) among Ugandan children; a cross-sectional study.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric disorder among the children. The burden of ADHD or its associated factors in Uganda are not known. The objective of this study was to determine the prevalence and the associated factors of ADHD among children attending the neurology and psychiatry clinics at Mulago National Referral Hospital. METHODS: Using the disruptive behavior scale (45 items), we investigated the presence of ADHD symptoms among children attending Mulago Hospital. Questionnaires were administered to the primary care-takers of the study participants to gather information on the factors associated with ADHD. All children were subject to a clinical examination. Children presumed to have ADHD, using the aforementioned rating scale were further assessed by a child psychiatrist to confirm the diagnosis and associated co-morbid conditions. RESULTS: The estimated prevalence of DSM-IV ADHD symptoms was 11%. Children aged less than 10 years were four times likely to have ADHD (OR 4.1, 95% CI 1.7-9.6, p < 0.001). The demographic factors independently associated with ADHD were age less than 10 years, male gender, history of maternal abnormal vaginal discharge during pregnancy, and no formal education or the highest level of education being primary school. CONCLUSION: The prevalence of ADHD among children attending the pediatric neurology and psychiatry clinics is high in our settings and is associated with delayed milestones. Early identification and addressing the co-morbid conditions associated with ADHD such as epilepsy, autism spectrum of disorder, conduct disorder, opposition defiant disorder and intellectual disability in our setting is needed.

Incidence and risk factors for first line anti retroviral treatment failure among Ugandan children attending an urban HIV clinic.

BACKGROUND: Early recognition of antiretroviral therapy (ART) failure in resource limited settings is a challenge given the limited laboratory facilities and trained personnel. This study aimed at describing the incidence, risk factors and the resistance associated mutations (RAMs) of first line treatment failure among HIV-1-infected children attending the Joint Clinical Research Centre (JCRC), Kampala, Uganda. METHODS: A retrospective cohort of 701 children who had been initiated on ART between January 2004 and September 2009 at the JCRC was studied. Data of children aged 6 months up to 18 years who had been started on ART for at least 6 months was extracted from the clinic charts. The children who failed the first-line ART were taken as cases and those who did not fail as the controls. Data was analysed using STATA version10. RESULTS: Of 701 children, 240(34%) failed on first line ART (cases) and 461(66%) did not fail (controls). The overall median time (IQR) to first line ART failure was 26.4 (18.9 - 39.1) months. The factors associated with treatment failure were poor adherence [(OR = 10, 95 CI: 6.4 - 16.7) p < 0.001], exposure to single dose nevirapine (sdNVP) [(OR = 4.2, 95% CI:1.8-9.4), p = 0.005] and a NVP containing regimen [(OR = 2.2,95% CI:1.4-3.6), p < 0.001]. Of 109 genotypic resistance profiles analyzed, the commonest non nucleoside reverse transcriptase inhibitor (NNRTI) resistance associated mutations (RAM) were: K103N (59; 54%)), Y181C (36; 27%)) and G190A (26; 24%)) while the commonest nucleoside reverse transcriptase inhibitor (NRTI) RAM was the M184V (89; 81%). Thymidine analogue- mutations (TAMs) were detected in 20% of patients. CONCLUSIONS: One in three children on first-line ART are likely to develop virological treatment failure after the first 24 months of therapy. Poor adherence to ART, a NVP based first-line regimen, prior exposure to sdNVP were associated with treatment failure.

The African Vaccine-Preventable Diseases Network: a vaccine advocacy initiative.

Achieving high and equitable childhood immunisation coverage in Africa will not only protect children from disability and premature death, it will also boost productivity, reduce poverty and support the economic growth of the continent. Thus, Africa needs innovative and sustainable vaccine advocacy initiatives. One such initiative is the African Vaccine-Preventable Diseases Network, formed in 2009. This association of immunisation practitioners, vaccinologists, paediatricians, and infectious disease experts provides a platform to advocate for the introduction of newly available vaccines (e.g. 10-valent and 13-valent pneumococcal conjugate and rotavirus vaccines) into the Expanded Programme on Immunisation (EPI) as well as increased and equitable coverage for established EPI vaccines.
