Human immunodeficiency virus transmission from a 24-year-old woman to her 78-year-old grandmother: a case report.

INTRODUCTION: Since its debut recognition in 1981, human immunodeficiency virus/acquired immunodeficiency syndrome has affected over 77 million people and has resulted in premature cessation of 35.4 million lives worldwide. Commonly, human immunodeficiency virus is transmitted by sexual contact across mucosal surfaces, by sharing of injecting equipment, through contaminated blood transfusions, and by maternal-infant exposure. Nevertheless, accidental transmission incidences involving family members are rare but possible. CASE PRESENTATION: A 78-year-old woman of African descent from Mtwara Region south of Tanzania was referred to us for further evaluation and treatment. She is 30 years postmenopausal and has a 35-year history of hypertension. Her last attendance to our institute was 11 months prior the index visit and she tested negative for human immunodeficiency virus. She came with complaints of weight loss, recurrent fevers, and cough. Her hematological tests revealed leukopenia with lymphocytosis, together with a normocytic normochromic anemia. Enzyme-linked immunosorbent assay for human immunodeficiency virus was positive, and she had a CD4 count of 177 cells/µL. We went back to history taking to identify the potential source of infection. We were informed that for the past 6 months, the 78-year-old lady has been living with her unwell 24-year-old granddaughter who has been divorced. The granddaughter had a history of recurrent fevers, significant weight loss, and a suppurative skin condition. As a way to show love and care, the old lady was puncturing the suppurative lesions with bare hands; then she would suck them to clear away the discharge. We requested to see the young lady, and she tested positive for human immunodeficiency virus. Both were started on tenofovir/lamivudine/dolutegravir combination plus cotrimoxazole 960 mg. The family was in total disarray following these findings. The patient was discharged through infectious diseases department and died of Pneumocystis jirovecii pneumonia 12 weeks later. CONCLUSIONS: Certain sociocultural norms that are believed to express love, care, and togetherness in developing rural communities, particularly Sub-Saharan Africa, have a potential of spreading human immunodeficiency virus, thus warranting prompt transformation.

Obesity epidemic in urban Tanzania: a public health calamity in an already overwhelmed and fragmented health system.

BACKGROUND: Worldwide, the epidemiological and demographic transitions have resulted in nutrition shift characterized by an increased consumption of high energy fast food products. In just over 3 decades, overweight and obesity rates have nearly tripled to currently affecting over a third of the global population. Notwithstanding the ever present under-nutrition burden, sub Saharan Africa (SSA) is witnessing a drastic escalation of overweight and obesity. We aimed to explore the prevalence and associated factors for obesity among residents of Dar es Salaam city in Tanzania. METHODS: Participants from this study were recruited in a community screening conducted during the Dar es Salaam International Trade Fair. Sociodemographic and clinical data were gathered using a structured questionnaire during enrollment. Dietary habits and anthropometric measurements were assessed using standard methods. All statistical analyses utilized STATA v11.0 software. Pearson Chi square and Student's T-test were used to compare categorical and continuous variables respectively. Logistic regression analyses were used to assess for factors associated with BMI ≥ 25. All tests were 2-sided and p < 0.05 was used to denote a statistical significance. RESULTS: A total of 6691 participants were enrolled. The mean age was 43.1 years and males constituted 54.2% of all participants. Over two-thirds of participants were alcohol consumers and 6.9% had a positive smoking history. 88.3% of participants were physically inactive, 4.7% had a history of diabetes mellitus and 18.1% were known to have elevated blood pressure. Overweight and obesity were observed in 34.8 and 32.4% of participants respectively. Among overweight and obese participants, 32.8% had a misperception of having a healthy weight. Age ≥ 40, female gender, a current working status, habitual breakfast skipping, poor water intake, high soft drink consumption, regular fast food intake, low vegetable and fruit consumption, alcohol consumption and hypertension were found to be independent associated factors for obesity. CONCLUSION: Amidst the ever present undernutrition in SSA, a significant proportion of participants had excess body weight. Concomitantly, the rates of physical inactivity and unhealthy eating are disproportionately high in Dar es Salaam. In view of this, community-based and multilevel public health strategies to promote and maintain healthy eating and physical activity require an urgent step-up in urban Tanzania.

Knowledge of cardiovascular risk factors among caretakers of outpatients attending a tertiary cardiovascular center in Tanzania: a cross-sectional survey.

BACKGROUND: Health literacy on cardiovascular diseases (CVDs) plays an effective role in preventing or delaying the disease onset as well as in impacting the efficacy of their management. In view of the projected low health literacy in Tanzania, we conducted this cross-sectional survey to assess for CVD risk knowledge and its associated factors among patient escorts. METHODS: A total of 1063 caretakers were consecutively enrolled in this cross-sectional study. An adopted questionnaire consisting of 22 statements assessing various CVD risk behaviors was utilized for assessment of knowledge. Logistic regression analyses were performed to assess for factors associated with poor knowledge of CVD risks. RESULTS: The mean age was 40.5 years and women predominated (55.7%). Over two-thirds had a body mass index (BMI) ≥25 kg/m2, 18.5% were alcohol drinkers, 3.2% were current smokers, and 47% were physically inactive. The mean score was 78.2 and 80.0% had good knowledge of CVD risks. About 16.3% believed CVDs are diseases of affluence, 17.4% thought CVDs are not preventable, and 56.7% had a perception that CVDs are curable. Low education (OR 2.6, 95%CI 1.9-3.7, p < 0.001), lack of health insurance (OR 1.5, 95%CI 1.1-2.3, p = 0.03), and negative family history of CVD death (OR 2.2, 95%CI 1.4-3.5, p < 0.001), were independently associated with poor CVD knowledge. CONCLUSIONS: In conclusion, despite of a good level of CVD knowledge established in this study, a disparity between individual's knowledge and self-care practices is apparent.

Medication adherence and survival among hospitalized heart failure patients in a tertiary hospital in Tanzania: a prospective cohort study.

OBJECTIVE: Management of heart failure is complex and multifaceted but adherence to medications remains the cornerstone of preventing avoidable readmissions, premature deaths, and unnecessary healthcare expenses. Despite of evidence-based efficacy on anti-failure drugs, poor adherence is pervasive and remains a significant barrier to improving clinical outcomes in heart failure population. RESULTS: We enrolled 459 patients with diagnosis of heart failure admitted at a tertiary cardiovascular hospital in Dar es Salaam, Tanzania. The mean age was 46.4 years, there was a female predominance (56.5%), 67.5% resided in urban areas and 74.2% had primary education. Of the 419 participants eligible for assessment of medication adherence, 313 (74.7%) had poor adherence and 106 (25.3%) had good adherence. Possession of a health insurance was found to be the strongest associated factor for adherence (adjusted OR 8.7, 95% CI 4.7-16.0, p < 0.001). Participants with poor adherence displayed a 70% increased risk for rehospitalization compared to their counterparts with good adherence (adjusted RR 1.7, 95% CI 1.2-2.9, p = 0.04). Poor adherence was found to be the strongest predictor of early mortality (HR 2.5, 95% CI 1.3-4.6, p < 0.01). In conclusion, Poor medication adherence in patients with heart failure is associated with increased readmissions and mortality.

Takayasu Arteritis Mistaken for Epilepsy: A Case Presenting With Convulsive Syncope.

Takayasu arteritis (TA) is a chronic inflammatory disease characterized by granulomatous vasculitis that predominantly manifests as panaortitis. This occlusive thromboaortopathy lacks pathognomonic features often resulting in a diagnostic dilemma leading to its under-recognition, misdiagnosis and delayed management. Although neurological manifestations are not uncommon in TA, convulsive syncope as an initial clinical presentation is extremely rare. We report a case of convulsive syncope as a manifesting symptom of TA. A 17-year-old male patient of African origin was referred to us from an upcountry regional hospital with a diagnosis of medically intractable epilepsy for cardiovascular review. He presented with a 28-week history of generalized tonic-clonic seizures followed by loss of consciousness. He denied history of recurrent headaches, fever, visual disturbances, arthralgias, claudication or unintentional weight loss. Physical examination revealed feeble left-sided brachial and radial pulses, elevated blood pressure, differences in blood pressure between arms and left-sided carotid and vertebral bruits. Computed tomography angiogram of his thoracic and abdominal aorta revealed changes suggestive of a diffuse arteritis. Additionally, magnetic resonance angiogram of the brain revealed total occlusion of the left common carotid, left internal carotid, left external carotid and left vertebral arteries. Based on the physical examination and radiological findings, we reached a diagnosis of TA. He was prescribed dexamethasone, methotrexate, acetylsalicylic acid and amlodipine. He had a remarkable recovery and was seizure-free for the last 5 months after discharge. TA may manifest with convulsive syncope mimicking epilepsy. Despite its rarity, presentations of this nature continue to challenge clinicians resulting in delayed diagnosis with irreversible life-threatening consequences to patients. In view of this, physicians should strive to take detailed history and perform thorough physical examination so as to timely pick the characteristic signs of TA especially in patients presenting with unanticipated symptoms.

Suicide Attempt Following Pacemaker Implantation in an Eighty-Three-Year-Old Male: A Case Report.

As the global population ages, cardiac pacing procedures are rising exponentially to keep pace with the increasing incidence of bradyarrhythmias. The efficacy of pacemakers is well established, but recipients may have poor psychosocial adaptation leading to development or exacerbation of mental disorders, that may manifest with anxiety, depressive symptoms or rarely suicidal tendencies. An 83-year-old male of African descent was referred to us for evaluation and expert management. He came with chief complaints of general body malaise, light-headedness, chest pain and fainting spells for about 6 months. He was diagnosed with hypertension 4 years prior, and there was no history of mental illness in the patient or his family. Echocardiography (ECHO) revealed features of hypertensive heart disease while electrocardiogram (ECG) showed features of third-degree heart block. He underwent successful pacing with a resultant ventricular paced rhythm. The patient was stable and symptom free post pacing, but on the fourth day he jumped off the window of the ward in the hospital's second floor. Post suicide attempt examination revealed epistaxis, right periorbital hematoma with a temporal lacerated wound and deformed ankles bilaterally. ECG showed a ventricular paced rhythm and the chest radiograph showed an intact pacemaker. Ophthalmological review was evident for right sided blepharospasm with massive chemosis and bilateral constricted reactive pupils. Radiological investigations showed right orbital fracture, stable C5 and C6 fractures, and bilateral bimalleolar fractures with ankle dislocation. Neurosurgical review was unremarkable and psychiatric review could not be performed. The patient died 18 h after the suicide attempt incidence. Emotional disturbances post pacing impairs the quality of life and in the worst case scenario could lead to unanticipated cessation of life. In view of this, thorough evaluation and monitoring of the patient's psychological well-being both pre and post pacing is paramount.
