Brugada-like syndrome presenting with monomorphic ventricular tachycardia and Brugada-type electrocardiogram unmasked by fever in an infant: a case report

Brugada syndrome is an autosomal-dominant arythmogenic genetic disorder associated with mutation in the SCN5A gene. We report a case of 3-month-old Tanzanian male who was admitted at Muhimbili National Hospital in Dar es Salaam, Tanzania with severe pneumonia, high fever and monomorphic ventricular tachycardia. The patient was treated with intravenous Amiodarone. In addition, oxygen, parenteral antibiotics, antipyretics and intravenous fluids were also given. About 2 hours and 20 minute later the child stabilized. An ECG obtained shortly after termination of ventricular tachycardia showed the typical J-point and coved ST elevation typical of  Brugada type I pattern. To the best of our knowledge, this is the first paediatric case with Brugada-type ECG to be reported in Sub-Saharan Africa. This case emphasizes the need to increase awareness among clinicians of clinical and genetic arythmogenic disorders. Multiple ECGs during and after febrile disorders should be performed in children who exhibit extreme tachycardia or signs of cardiac failure

Centrally-located pulmonary hamartoma diagnosed in a 16-year-old boy presenting with chronic chest pain: a case report

Pulmonary hamartomas are the most common benign tumors of the lung. They are usually diagnosed incidentally while evaluating for other conditions. These tumors have been shown to be uncommon below the age of 25 years. We report a case of a 16-year-old male who presented with chronic chest pain and was histologically confirmed to have pulmonary hamartoma. The tumor was successfully resected. This is the first case of hamartoma to be reported in our country, and the atypical age at presentation together with the tumor’s position makes it more unique. In conclusion, although very rare, pulmonary hamartomas can occur in young age with the central location. Clinically, the presentation is usually non-specific and the diagnosis is mostly incidental while investigating other conditions. There is a need to increase awareness among clinicians on hamartomas to improve early treatment for this rare disease in the adolescents

Impact of spatio-temporal simulations of rat damage on yield of rice (Oryza sativa L.) and implications for rodent pest management

Rodents often damage crops throughout the growing season, from germination to harvest, thus making it difficult to understand the cumulative effects of rodent damage for crops such as rice that are able to partially compensate for damage. Compensation can make it difficult to understand the impact of variable rodent damage in terms of when the damage occurs, its severity and thus when, whether and how rodent pests should be controlled. The compensatory responses of rice to simulated rat damage carried out at different growth stages and at different spatial levels of severity showed that higher yield was recorded during the wet season in comparison to the dry season. However, yield loss was observed during all cropping stages for all levels of simulated damage for wet and dry season crops, with significant compensation noted at the transplanting [14 days after sowing (DAS)] and vegetative (45 DAS) stages. Only damage at the maturity (110 DAS) stage resulted in significant reductions in rice crop yield. Seasonal differences suggest water availability was an important factor that perhaps enhanced rice production. The ability of rice to compensate for early rodent damage could potentially reduce a farmer's perception of damage. However, failing to control rodents at these earlier crop growth stages could lead to increased rodent populations at the time of maturity when compensatory effects are limited

Risk factors for mortality among tuberculosis patients on treatment at Bugando Medical Centre in north-western Tanzania: a retrospective cross-sectional study

 Background: Tuberculosis (TB) is still an important cause of morbidity and mortality worldwide. Though it can effectively be treated, still a significant proportion of patients die on the course of their treatment. The objective of this study was to determine the outcome and risk factors of mortality among patients diagnosed with TB in a tertiary hospital in north-western Tanzania.Methods: A retrospective cross sectional study was done among all patients diagnosed with TB between January and December 2015 at Bugando Medical Centre. Information of demographic characteristics, smear positivity, haemoglobin concentration, HIV status, CD4 counts for HIV positive patients and treatment outcomes were collected and analysed. TB treatment outcomes as dead or alive were calculated and logistic regression was done to determine the factors associated with increased risk of death of patients on anti-TB treatment.Results: In total 701 patients were diagnosed with TB during the study period. Of these, 361 (51.5%) were males with a median age of 38 (IQR 27- 47) and 421 (60.06%) were younger than 40 years. Majority of the participants 409 (58.35%) had smear positive pulmonary tuberculosis and about half of patients (51.07%) tested positive for HIV. Of the enrolled patients 610 (87.02%) were alive at the end of TB treatment while 91 (12.98%) died in the course of treatment. The odds of deaths of patients on anti-TB treatment were strongly associated with male sex, HIV co infection and severe anaemia.Conclusion: The proportion of patients who die from TB treatment at BMC is high, with an increased risk of death among HIV co-infected, older than 40 years and severely anaemic patients. Improvement of strategies for early diagnosis and prompt treatment of TB patients will potentially improve treatment outcome

The feasibility of integrating alcohol risk-reduction counseling into existing VCT services in Kenya

This pretest-posttest separate-sample study with intervention and comparison groups documented the abilities and willingness of trained voluntary counseling and testing (VCT) service providers to integrate alcohol screening and risk reduction counseling into their routine service delivery. Pre-test (n=1073) and post-test data (n=1058) were collected from different clients exiting from 25 VCT centers. A 12-month intervention that required all VCT providers from the intervention groups to screen all VCT clients for their alcohol use and offer them brief risk reduction alcoholrelated counseling was implemented. At post-test, the intervention group clients (n=456) had better study outcomes than the comparison group clients (n=602). Intervention clients were more likely to report that their VCT service provider had: asked them about their alcohol use (83% vs. 41%:

Knowledge, Attitudes, and Practices Associated with Chronic Kidney Disease in Northern Tanzania: A Community-Based Study.

Non-communicable diseases (NCDs) are a leading cause of death among adults in sub-Saharan Africa, and chronic kidney disease (CKD) is a growing public health threat. Understanding knowledge, attitudes, and practices associated with NCDs is vital to informing optimal policy and public health responses in the region, but few community-based assessments have been performed for CKD. To address this gap, we conducted a cross-sectional survey of adults in northern Tanzania using a validated instrument. Between January and June 2014, we administered a structured survey to a random sample of adults from urban and rural communities. The validated instrument consisted of 25 items designed to measure knowledge, attitudes, and practices associated with kidney disease. Participants were also screened for CKD, diabetes, hypertension, and human immunodeficiency virus. We enrolled 606 participants from 431 urban and rural households. Knowledge of the etiologies, symptoms, and treatments for kidney disease was low (mean score 3.28 out of 10; 95% CI 2.94, 3.63). There were no significant differences by CKD status. Living in an urban setting and level of education had the strongest independent associations with knowledge score. Attitudes were characterized by frequent concern about the health (27.3%; 20.2, 36.0%), economic (73.1%; 68.2, 77.5%), and social impact (25.4%; 18.6, 33.6%) of kidney disease. Practices included the use of traditional healers (15.2%; 9.1, 24.5%) and traditional medicines (33.8%; 25.0, 43.9%) for treatment of kidney disease as well as a willingness to engage with mobile-phone technology in CKD care (94.3%; 90.1, 96.8%). Community-based adults in northern Tanzania have limited knowledge of kidney disease. However, there is a modest knowledge base upon which to build public health programs to expand awareness and understanding of CKD, but these programs must also consider the variety of means by which adults in this population meet their healthcare needs. Finally, our assessment of local attitudes suggested that such public health efforts would be well-received

Post-Partum Pituitary Insufficiency and Livedo Reticularis Presenting a Diagnostic Challenge in a Resource Limited Setting in Tanzania: A Case Report, Clinical Discussion and Brief Review of Existing Literature.

Pituitary disorders following pregnancy are an important yet under reported clinical entity in the developing world. Conversely, post partum panhypopituitarism has a more devastating impact on women in such settings due to high fertility rates, poor obstetric care and scarcity of diagnostic and therapeutic resources available. A 37 year old African female presented ten years post partum with features of multiple endocrine deficiencies including hypothyroidism, hypoadrenalism, lactation failure and secondary amenorrhea. In addition she had clinical features of an underlying autoimmune condition. These included a history of post-partum thyroiditis, alopecia areata, livedo reticularis and deranged coagulation indices. A remarkable clinical response followed appropriate hormone replacement therapy including steroids. This constellation has never been reported before; we therefore present an interesting clinical discussion including a brief review of existing literature. Post partum pituitary insufficiency is an under-reported condition of immense clinical importance especially in the developing world. A high clinical index of suspicion is vital to ensure an early and correct diagnosis which will have a direct bearing on management and patient outcome

Spatio-temporal patterns in the distribution of the multi-mammate mouse, Mastomys natalensis, in rice crop and fallow land habitats in Tanzania

An understanding of the dispersion patterns of a pest is an important pre-requisite for developing an effective management programme for the pest. In this study, rodents were trapped in two rice fields and two fallow fields for three consecutive nights each month from June 2010 to May 2012. Mastomys natalensis was the most abundant rodent pest species in the study area, accounting for > 95% of the trapped rodent community. Rattus rattus, Dasymys incomtus, Acomys spinosissimus and Grammomys dolichurus comprised relatively small proportions of the trapped population. Morisita’s index of dispersion was used to measure the relative dispersal pattern aggregate, random, uniform) of individuals across each trapping grid as a means of comparing rodent distribution in rice and fallow fields over time. This analysis revealed that the rodents in rice fields generally exhibited an aggregated spatio-temporal distribution. However, the rodents in fallow fields were generally less aggregated, approaching a random distribution in some habitats and seasons. Heat maps of trapping grids visually confirmed these dispersal patterns, indicating the clumped or random nature of captured rodents. ANOVA showed that the parameters of habitat (rice, fallow), crop stage (transplanting, vegetative, booting, maturity) and cropping season (wet, dry) all significantly impacted the number of rodents captured, with the vegetative, dry season, fallow habitat having the highest number of rodents; and the transplanting, wet season, rice habitat with the least number of rodents. Therefore, such spatio-temporal patterns can serve as a tool for developing stratified biodiversity sampling plans for small mammals and decision making for rodent pest management strategies
