Advanced abdominal ectopic pregnancy and the role of antenatal ultrasound scan in its diagnosis and management.

Abdominal pregnancy is a very rare form of ectopic gestation in which implantation occurs in the peritoneal cavity. It accounts for about 1% of all ectopic pregnancies and is associated with a higher risk of morbidity and mortality due to complications such as preeclampsia, placenta abruption, and oligohydromnios, which necessitate pregnancy termination before term, and the risk of massive hemorrhage associated with abnormal placentation. We present a case of advanced abdominal ectopic pregnancy, diagnosed in the second trimester and complicated by anhydramnios. An abdominal ultrasound scan showed a nongravid uterus and a single live extrauterine fetus within the abdominal cavity, with no surrounding liquor at 23 weeks and 3 days average gestational age. Mother was consented and an emergency laparatomy performed. A premature baby was delivered but died in Neonatal Intensive Care Unit (NICU) after 4 hours due to severe acute respiratory distress syndrome. Mother had good postoperative recovery. Advanced abdominal ectopic pregnancy though very rare, is associated with complications that lead to early termination. Ultrasound scan is a reliable tool for the diagnosis of abdominal pregnancy in settings with limited access to Magnetic Resonance Imaging (MRI). It should be recommended to all mothers at their earliest antenatal care (ANC) visit to help determine the site of pregnancy and guide further intervention.

Unusual presentation of Pott disease and diagnostic challenges in a resource-limited setting: a case report.

BACKGROUND: Pott disease is rare and responsible for only 1%-2% of all tuberculosis cases. It poses diagnostic challenges in resource-limited settings due to unusual presentation and limited investigative capacity, resulting in debilitating sequelae if diagnosed late. CASE PRESENTATION: We present a case of severe Pott disease of the lumbar spine, with a large paravertebral abscess tracking down to the gluteal region in a 27-year-old Black African Ugandan woman living with human immunodeficiency virus, whose main complaint was right lower abdominal pain. She was initially misdiagnosed from the peripheral clinics as a case of lumbago and later with a psoas abscess. The diagnosis of severe Pott disease was established at the regional referral hospital following an abdominal computed tomography scan, and the patient was appropriately initiated on anti-tuberculosis drugs. However, only abscess drainage and provision of a lumbar corset were possible, with no neurosurgical intervention done on the spine due to financial constraints. Clinical review at 2, 6, and 12 months revealed improvement. CONCLUSIONS: Pott disease may present with non-specific symptoms such as abdominal pain resulting from pressure effects of an expansile cold abscess. This, coupled with limited diagnostic capacity in resource-limited settings; results in significant morbidity and possible mortality. Hence, there is need to train clinicians to increase their index of suspicion and equip health units with basic radiological equipment, such as x-ray, for timely detection and subsequent management of Pott disease.

One year overall survival of wilms tumor cases and its predictors, among children diagnosed at a teaching hospital in South Western Uganda: a retrospective cohort study.

BACKGROUND: Wilms tumor (WT) is the second most common solid tumor in Africa with both low overall survival (OS) and event-free survival (EFS) rates. However, no known factors are predicting this poor overall survival. OBJECTIVE: The study was to determine the one-year overall survival of WT cases and its predictors among children diagnosed in the pediatric oncology and surgical units of Mbarara regional referral hospital (MRRH), western Uganda. METHODOLOGY: Children's treatment charts and files diagnosed and managed for WT were retrospectively followed up for the period between January 2017 to January 2021. Charts of children with histologically confirmed diagnoses were reviewed for demographics, clinical and histological characteristics, as well as treatment modalities. RESULTS: One-year overall survival was found to be 59.3% (95% CI: 40.7-73.3), with tumor size greater than 15 cm (p 0.021) and unfavorable WT type (p 0.012) being the predominant predictors. CONCLUSION: Overall survival (OS) of WT at MRRH was found to be 59.3%, and predictive factors noted were unfavorable histology and tumor size greater than 115 cm.

Efficacy of extended focused assessment with sonography for trauma using a portable handheld device for detecting hemothorax in a low resource setting; a multicenter longitudinal study.

INTRODUCTION: Chest trauma is one of the most important and commonest injuries that require timely diagnosis, accounting for 25-50% of trauma related deaths globally. Although CT scan is the gold standard for detection of haemothorax, it is only useful in stable patients, and remains unavailable in most hospitals in low income countries. Where available, it is very expensive. Sonography has been reported to have high accuracy and sensitivity in trauma diagnosis but is rarely used in trauma patients in low income settings in part due to lack of the sonography machines and lack of expertise among trauma care providers. Chest X-ray is the most available investigation for chest injuries in low income countries. However it is not often safe to wheel seriously injured, unstable trauma patients to X-ray rooms. This study aimed at determining the efficacy of extended focused assessment with sonography for trauma (eFAST) in detection of haemothorax using thoracostomy findings as surrogate gold standard in a low resource setting. METHODS: This was an observational longitudinal study that enrolled 104 study participants with chest trauma. Informed consent was obtained from all participants. A questionnaire was administered and eFAST, chest X-ray and tube thoracotomy were done as indicated. Data were analysed using SPSS version 22. The sensitivity, specificity, predictive values, accuracy and area under the curve were determined using thoracostomy findings as the gold standard. Ethical approval for the study was obtained from the Research and Ethics Committee of Kampala International University Western Campus REC number KIU-2021-53. RESULTS: eFAST was found to be superior to chest X-ray with sensitivity of 96.1% versus 45.1% respectively. The accuracy was also higher for eFAST (96.4% versus 49.1%) but the specificity was the same at 100.0%. The area under the curve was higher for eFAST (0.980, P = 0.001 versus 0.725, P = 0.136). Combining eFAST and X-ray increased both sensitivity and accuracy. CONCLUSION: This study revealed that eFAST was more sensitive at detecting haemothorax among chest trauma patients compared to chest X-ray. All patients presenting with chest trauma should have bedside eFAST for diagnosis of haemothorax.

Etiology, Clinical Presentations, and Short-Term Treatment Outcomes of Extrahepatic Obstructive Jaundice in South-Western Uganda.

Background: The diagnosis of extrahepatic obstructive jaundice (EHOJ) remains a challenge and is often made late in low-resource settings. Systematic data are limited on the etiology and prognosis of patients with obstructive jaundice in Uganda. The objective of this study was to determine the etiology, clinical presentations, and short-term treatment outcomes of patients managed for EHOJ at Mbarara Regional Referral Hospital (MRRH) in south-western Uganda. Methods: Between September 2019 and May 2020, we prospectively enrolled a cohort of patients who presented with EHOJ at MRRH. A pretested, semi-structured data collection tool was used to abstract data from both the study participants and their files. Results: A total of 72 patients, 42 (58.3%) of whom were male with a median age of 56 (range of 2 months to 95 years) were studied. Forty-two (58.3%) participants had malignancies: Pancreatic head tumors 20 (27.8%), cholangiocarcinoma 13 (18.1%), duodenal cancers 5 (6.94%), and gall bladder cancer 4 (5.6%). The remaining 30 (41.7%) participants had benign etiologies: choledocholithiasis 10 (13.9%), biliary atresia 7 (9.7%), pancreatic pseudo cyst 6 (8.3%), Mirizzi syndrome 5 (6.9%) and 1 (1.4%) each of chronic pancreatitis and choledochal cyst. Sixty-seven (93.1%) patients presented with right upper quadrant tenderness, 65 (90.3%) abdominal pain and 55 (76.3%) clay-colored stool. Cholecystectomy 11 (25.6%) and cholecystojejunostomy + jejunojejunostomy 8 (18.6%) were the commonest procedures performed. Twelve (17.0%) of cases received chemotherapy (epirubicin/cisplatin/capecitabine) for pancreatic head tumors and (gemcitabine/oxaliplatine) for cholangiocarcinoma. Mortality rate was 29.2% in the study, of which malignancy carried the highest mortality 20 (95.24%). Conclusion: Malignancy was the main cause of EHOJ observed in more than half of the patients. Interventions aimed at early recognition and appropriate referral are key in this population to improve outcomes.

Urinary bladder cavernous hemangioma in a 3-year-old: A rare case report.

Cavernous hemangioma (CH) of urinary bladder occurs relatively infrequently, accounting for 0.6% of all bladder tumors. This tumor may occur sporadically or coexist with other benign and malignant vascular lesions. In this report, we present a rare case of CH in a 3-year-old Ugandan girl. A 3-year-old girl was referred to Mbarara Regional Referral Hospital (MRRH) for urological evaluation following a 3-year history of intravaginal swelling, dysuria, and heavy hematuria resulting in anemia. Imaging was consistent with polypoid bladder mass arising from the bladder trigone. Embryonal rhabdomyosarcoma was suspected based on clinical eyeballing. She was worked up for chemotherapy and received 26 cycles of vincristine sulfate, actinomycin-d, and cyclophosphamide (VAC). Biopsy and fulguration were performed after optimizing the patient. Histopathology confirmed CH. The surgery was uneventful and resulted in complete cure. CH should be considered in the differential diagnosis of childhood genitourinary masses. It is a rare entity in the real-life clinical practice and therefore can be overlooked. Excision biopsy and histology should be performed before initiating the patients to chemotherapy. CH is very insensitive to chemotherapy and therefore surgery maybe adequate in resource-limited settings.

An Analysis of Stroke Risk Factors by HIV Serostatus in Uganda: Implications for Stroke Prevention in Sub-Saharan Africa.

OBJECTIVE: HIV infection is an important stroke risk factor in sub-Saharan Africa.  However, data on stroke risk factors in the era of antiretroviral therapy (ART) are sparse. We aimed to determine if stroke risk factors differed by HIV serostatus in Uganda. METHODS: We conducted a matched cohort study, enrolling persons living with HIV (PWH) with acute stroke, matched by sex and stroke type to HIV uninfected (HIV-) individuals. We collected data on stroke risk factors and fitted logistic regression models for analysis. RESULTS: We enrolled 262 participants:105 PWH and 157 HIV-. The median ART duration was 5 years, and the median CD4 cell count was 214 cells/uL. PWH with ischemic stroke had higher odds of hypertriglyceridemia (AOR 1.63; 95% CI 1.04, 2.55, p=0.03), alcohol consumption (AOR 2.84; 95% CI 1.32, 6.14, p=0.008), and depression (AOR 5.64; 95%CI 1.32, 24.02, p=0.02) while HIV- persons with ischemic stroke were more likely to be > 55 years of age (AOR 0.43; 95%CI 0.20-0.95, p=0.037), have an irregular heart rhythm (AOR 0.31; 95%CI 0.10-0.98, p=0.047) and report low fruit consumption (AOR 0.39; 95%CI 0.18-0.83, p=0.014).  Among all participants with hemorrhagic stroke (n=78) we found no differences in the prevalence of risk factors between PWH and HIV-. CONCLUSIONS: PWH with ischemic stroke in Uganda present at a younger age, and with a combination of traditional and psychosocial risk factors. By contrast, HIV- persons more commonly present with arrhythmia. A differential approach to stroke prevention might be needed in these populations.

Hair-on-End Sign in a 9-Year-Old Girl Presenting with Acute Stroke in Sickle Cell Disease.

BACKGROUND: The hair-on-end (HOE) sign is a rare finding seen in the diploic space on skull radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) with the appearance of long, thin vertical striations of calcified spicules perpendicular to the bone surface that looks like hair standing on end. It is classically seen in children/adolescents with hemolytic anemias, in particular, thalassemia major and sickle cell disease. Here, we present a 9-year-old Ugandan girl who presented with stroke in whom head CT demonstrated cerebral intraparenchymal hemorrhage and multiple infarcts on the left with HOE sign. Hb electrophoresis confirmed the diagnosis of sickle cell anemia. CASE SUMMARY: We present a 9-year-old Ugandan girl who presented with an unexplained stroke that preceded an episode of acute headache, vomiting, followed by focal convulsions and altered consciousness. Clinical findings revealed severe pallor of the conjunctivae and mild scleral icterus. CT demonstrated right cerebral intraparenchymal hemorrhage, multiple high cerebral infarcts on the right and evidence of extra medullary hematopoiesis with a classical HOE sign. Hemoglobin (Hb) electrophoresis confirmed sickle cell disease (SCD). The child was then initiated on hydroxyurea, antibiotics, analgesics and intravenous fluids. She improved and was discharged 16 days later. Follow-up of the child was uneventful. CONCLUSION: HOE sign is a complication of chronic hemolysis usually seen in patients with thalassemia and sickle cell anemia. It is a rare finding that clinicians should be well conversant with, especially in Africa where sickle cell disease is common.

Prevalence and correlates of carotid plaque in a mixed HIV-serostatus cohort in Uganda.

BACKGROUND: The extent to which the risk of atherosclerotic cardiovascular disease (ACVD) is increased among people living with HIV (PLWH) in sub-Saharan Africa remains unknown. SETTING: Cross-sectional analysis nested within the Ugandan Noncommunicable Diseases and Aging Cohort, including PLWH in rural Uganda > 40 years taking antiretroviral therapy (ART) for at least 3 years, and a population-based control group of HIV-uninfected age- and sex-matched persons. METHODS: We conducted carotid ultrasonography and collected ACVD risk factor data. Our outcome of interest was carotid plaque, defined as > 1.5 mm thickness from the intima-lumen interface to the media-adventitia interface. We fit multivariable logistic regression models to estimate correlates of carotid plaque including HIV-specific and traditional cardiovascular risk factors. RESULTS: We enrolled 155 (50.2%) PLWH and 154 (49.8%) HIV-uninfected comparators, with a mean age of  51.4 years. Among PLWH, the median CD4 count was 433 cells/mm3 and 97.4% were virologically suppressed. Carotid plaque prevalence was higher among PLWH (8.4% vs 3.3%). HIV infection (aOR 3.90; 95% CI 1.12-13.60) and current smokers (aOR 6.60; 95% CI 1.22-35.80) had higher odds of carotid plaque, whereas moderate (aOR 0.13, 95% CI 0.01-1.55) and vigorous intensity of physical activity (aOR 0.34, 95% CI 0.07-1.52) were associated with decreased odds of carotid plaque. CONCLUSION: In rural Uganda, PLWH have higher prevalence of carotid plaque compared to age- and sex-matched HIV-uninfected comparators. Future work should explore how biomedical and lifestyle modifications might reduce atherosclerotic burden among PLWH in the region.

Validation of the Intracerebral Hemorrhage Score in Uganda.

Background and Purpose- Rates of intracerebral hemorrhage (ICH) are estimated to be highest globally in sub-Saharan Africa. However, outcomes of ICH are poorly described and standard prognostic markers for ICH have not been validated in the region. Methods- We enrolled consecutive patients with computed tomography-confirmed ICH at a referral hospital in southwestern Uganda. We recorded demographic, clinical, and radiographic features of ICH, and calculated ICH scores. We fit Poisson regression models with robust variance estimation to determine predictors of case fatality at 30 days. Results- We enrolled 73 individuals presenting with computed tomography-confirmed ICH (mean age 60 years, 45% [33/73] female, and 14% [10/73] HIV-positive). The median ICH score was 2 (interquartile range, 1-3; range, 0-5). Case fatality at 30 days was 44% (32/73; 95% CI, 33%-57%). The 30-day case fatality increased with increasing ICH score of 0, 1, and 5 from 17%, 23%, to 100%, respectively. In multivariable-adjusted models, ICH score was associated with case fatality (adjusted relative risk, 1.48; 95% CI, 1.23-1.78), as were HIV infection (adjusted relative risk, 1.92; 95% CI, 1.07-3.43) and female sex (adjusted relative risk, 2.17; 95% CI, 1.32-3.59). The ICH score moderately improved with the addition of a point each for female sex and HIV serostatus (0.81 versus 0.73). Conclusions- ICH score at admission is a strong prognostic indicator of 30-day case fatality in Uganda. Our results support its role in guiding the care of patients presenting with ICH in the region.
