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 …

Imaging & Diagnostic Radiology, East Africa
Hydatid (Echinococcal) disease often involves the liver and lungs but in sporadic cases, it can involve cardiac structures. A 24-year-old male was referred with symptoms of cough and shortness of breath and a provisional diagnosis of metastatic disease of unknown primary to the lung, which was based on a chest X-ray (CXR). Incidentally, on echocardiogram, he was found to have right ventricular (RV) and myocardial multiseptated cysts, which were compatible with cardiac echinococcosis, as the patient had multiple bilateral lung cysts as well. Imaging with ultrasound, computed tomography (CT) scan, and magnetic resonance imaging (MRI) has ameliorated the diagnosis of …

Endobronchial Tuberculosis: A Rare Presentation, Nadeem Kassam, Omar M. Aziz, Samina Somji, Grace Shayo
Internal Medicine, East Africa
Endobronchial tuberculosis (EBTB) is an infection of the tracheobronchial tree by Mycobacterium tuberculosis. It is common among young females. Patient can present with fever, cough, wheeze, with or without any constitutional symptoms. It presents as a diagnostic dilemma, as patient sputum smear can be false negative. CT scan may or may not show any abnormality, or any endobronchial lesion. Bronchoscopy with bronchoalveolar lavage and biopsy offers the diagnostic choice. We hereby report a case of a young immunocompetent Asian female who was found to have endobronchial pathology, leading to diagnosis and timely therapy.

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
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
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 …

Effect Of Unmaskes On Delivering Difficult News Among Residents, Karishma Sharma
Master of Medicine in Internal Medicine
Background: Effective delivery of difficult news to patients and family has been shown to improve the physician-patient relationship, quality of care, and overall patient satisfaction. However, delivery of difficult news (DDN) remains a challenging task for even the most experienced providers. Little has been studied about delivery of difficult news by resident physicians in the sub-Saharan setting. We developed a 4-minute, easily accessible, graphic video using the mnemonic UNMASKES to help improve delivery of difficult news by resident physicians at our institution and their patients. Objective: To determine the impact of a short training video called UNMASKES in helping resident …
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 …

Despite ongoing efforts, sub-Saharan Africa faces a higher cervical cancer burden than anywhere else in the world. Besides HPV infection, definitive factors of cervical cancer are still unclear. Particular states of the cervicovaginal microbiota and viral infections are associated with increased cervical cancer risk. Notably, HIV infection, which is prevalent in sub-Saharan Africa, greatly increases risk of cervicovaginal dysbiosis and cervical cancer. To better understand and address cervical cancer in sub-Saharan Africa, a better knowledge of the regional cervicovaginal microbiome is required This review establishes current knowledge of HPV, HIV, cervicovaginal infections, and the cervicovaginal microbiota in sub-Saharan Africa. Because …

Nebraska Center for Virology: Faculty Publications
Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent of Kaposi’s sarcoma (KS), one of the most prevalent cancers of people living with HIV/AIDS in sub-Saharan Africa. The seroprevalence for KSHV is high in the region, and no prophylactic vaccine against the virus is available. In this study, we characterized the antigenic targets of KSHV-specific neutralizing antibodies (nAbs) in asymptomatic KSHV-infected individuals and KS patients with high nAbs titers. We quantified the extent to which various KSHV envelope glycoproteins (gB, ORF28, ORF68, gH, gL, gM, gN and gpK8.1) adsorbed/removed KSHV-specific nAbs from the plasma of infected individuals. Our study revealed that …

Nebraska Center for Virology: Faculty Publications
Tanzania faces one of the highest cervical cancer burdens in the world. Recent work has suggested that the bacterial family Mycoplasmataceae is associated with higher levels of human papillomavirus (HPV), human immunodeficiency virus (HIV), and pre-cancerous cervical lesions. Mycoplasmataceae infection in Tanzania is not well understood, especially when considering the differences between sexually transmitted species of Mycoplasmataceae. To establish the prevalence of common Mycoplasmataceae cervical infections and evaluate their relationship with risk factors for cervical cancer, 1160 Tanzanian women responded to an epidemiological questionnaire and were tested for HIV, HPV, cervical lesions, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma spp., and Lactobacillus …

School of Biological Sciences: Dissertations, Theses, and Student Research
Kaposi’s sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV-8), is the etiological agent of Kaposi’s sarcoma (KS), and is also associated with two B cell malignancies, primary effusion lymphoma and multicentric Castleman's disease. The distribution of KSHV varies globally with high prevalence in some areas of sub-Saharan Africa (SSA), where seroprevalence can be as high as 80%. It is estimated that nearly 44,000 new cases of KS emerge annually globally, with the highest incidents occurring in Africa, where KSHV is endemic. Currently, there is no prophylactic vaccine against KSHV, and efforts to develop prophylactic vaccines have been limited. …
