Post-Vaccination Pharyngeal-Cervical-Brachial Variant Of Guillain-Barré Syndrome, Funmilola T. Taiwo, Daniel E. Ezuduemoih, Philip Adebayo

Internal Medicine, East Africa

The pharyngeal-cervical-brachial (PCB) variant of Guillain-Barré syndrome (GBS) is very rare. It is characterized by weakness of the upper extremities associated with bulbar symptoms and facial diplegia. Documented cases were post-infectious, a post-vaccination occurrence has not been documented in the available literature. Even rarer is the occurrence of any variant of GBS following the mumps measles rubella (MMR) vaccine. The neurophysiological hallmark of PCB variant of GBS is a combination of myelinopathy and axonopathy, hence, its consideration as a subtype of the acute motor axonal neuropathy (AMAN) variant. It should be suspected in any case of acute-onset flaccid symmetrical weakness …

Video Analysis Of Newborn Resuscitations After Simulation-Based Helping Babies Breathe Training, Ingunn Anda Haug, Kari Holte, Catherine L. Chang, Carolyn Purington, Joar Eilevstjønn, Anita Yeconia, Hussein Kidanto, Hege L. Ersdal

Obstetrics and Gynaecology, East Africa

Background: Simulation-based Helping Babies Breathe (HBB) training is currently rolled-out in around 80 low-income countries with various results.

Method: Workflow was analyzed in 76 video-recorded newborn resuscitations performed by regularly HBB-trained nurse-midwives over 3 years in rural Tanzania.

Results: Actual newborn resuscitation practice deviated from HBB intention/guideline: most newborns underwent prolonged suction and stimulation before ventilation; ventilation was delayed and frequently interrupted. Nurse-midwives often worked together.

Conclusions:There is a gap between training intention and clinical practice. HBB trainings should focus more on urgency, ventilation skills, and team training. Combining clinical debriefing with HBB simulations could facilitate continuous learning and …

Nebraska Center for Virology: Faculty Publications

Despite the close association between Kaposi’s sarcoma (KS) and immune dysfunction, it remains unclear whether tumor infiltrating immune cells (TIIC), by their absence, presence, or dysfunction, are mechanistically correlated with KS pathogenesis. Therefore, their potential capacity to serve as prognostic biomarkers of KS disease progression or control is unclear. Because epidemic-KS (EpKS) occurs with HIV-1 co-infection, it is particularly important to compare TIIC between EpKS and HIV-negative African endemic-KS (EnKS) to dissect the roles of HIV-1 and Kaposi Sarcoma-associated herpesvirus (KSHV) in KS pathogenesis. This cross-sectional study of 13 advanced KS (4 EnKS, 9 EpKS) patients and 3 healthy controls …

Revisiting Caroli Syndrome In A Tanzanian Patient, Casmir Wambura, Munish Sharma, Salim Surani

Internal Medicine, East Africa

Caroli disease and Caroli syndrome are two rare congenital diseases of the intrahepatic bile ducts. Caroli syndrome is characterized by the saccular dilatation of intrahepatic bile ducts associated with congenital hepatic fibrosis. It is rarely diagnosed in childhood. We hereby describe a case of Caroli syndrome in a young Tanzanian female who had abdominal pain and distension since childhood. Her history suggested the presence of portal hypertension possibly from congenital hepatic fibrosis. The diagnosis was reached based on ultrasound, computed tomography (CT) scan of the abdomen, and magnetic resonance cholangiopancreatography (MRCP)


Prevalence And Factors Associated To Incidental Prostate Carcinoma Among Patients Undergoing Turp For Benign Prostatic Enlargement., Isaac Herman Mawalla Jan 2020

Prevalence And Factors Associated To Incidental Prostate Carcinoma Among Patients Undergoing Turp For Benign Prostatic Enlargement., Isaac Herman Mawalla

Master of Medicine in General Surgery

Background: Prostate carcinoma carries higher morbidity and mortality when diagnosed late. Prostate cancer screening is paramount, however, there are no specific clinical signs for early-stage prostate cancer. As an independent variable, prostate-specific antigen is an established predictor of cancer. Incidental prostate cancer is detected by histological examination of resected biopsy tissue that had been previously diagnosed as benign. In the current PSA-use era the prevalence of incidental prostate cancer ranges from 1.4 to 13%. The prevalence in Tanzania as published by Gunda et al was 21.71%. This is alarmingly high. However, in his study, patients with high prostate-specific antigens were …

Perceptions Of Surgeons On Surgical Antibiotic Prophylaxis Use At Aga Khan Hospital, Dar Es Salaam., Elizabeth Elibariki Mmari

Master of Medicine in General Surgery

Introduction: Surgical site infections are a major cause of morbidity and mortality among operated patients. The use of antibiotic prophylaxis in prevention and reduction of incidence of surgical site infection is widespread. In spite of the accessibility of universal and national guidelines for surgical prophylaxis, recent studies surveying the present routine of prophylaxis have demonstrated overutilization of a wide range antibacterial medications for a single patient. Few studies have shown qualitatively factors influencing this, and perceptions of surgeons on surgical antibiotic prophylaxis use. Unfortunately, none of these studies have been done in Tanzania. Objective: To describe the perceptions of surgeons …

Utility Of Glasgow-Blatchford Scoring System In Identification Of Low Risk Patients With Upper Gastrointestinal Bleeding In Emergency Departments In Dar Es Salaam Hospitals, Tanzania, Selestin D. Mpiri

Master of Medicine in Internal Medicine

Background: Acute upper gastrointestinal bleeding (UGIB) remains a common cause of visits to the Emergency Department (ED). To stratify the risk of complications, rebleeding, need for clinical intervention, or death, several clinical scores are in use. Glasgow-Blatchford Score (GBS) is an excellent risk assessment tool and has shown to accurately identify patients with a low risk of death or requiring intervention. In urban Tanzania, there is a lack of standardized protocol and a well-validated risk assessment tool for analyzing patients presenting with UGIB symptoms. Good performance of GBS score and its use will help to reduce unnecessary emergency endoscopies and …
