Gall bladder schistosomiasis diagnosed incidentally post laparoscopic cholecystectomy: A case report

Introduction and importance: Schistosomiasis is a neglected tropical disease caused by parasitic worms of the genus Schistosoma. It primarily affects the intestines, liver, and urinary tract however, rare cases have been reported where the parasite invades other organs. This case report presents an incidental finding of schistosomiasis, upon histopathology evaluation, in a patient who underwent laparoscopic cholecystectomy for symptomatic gallstone disease with recurrent attacks of cholecystitis. Case presentation: We present the case of a 42-year-old female patient who presented to the emergency department with symptoms and signs suggestive of acute cholecystitis. She underwent conservative management with interval laparoscopic cholecystectomy with histopathology findings of Schistosoma eggs within the walls of the gallbladder. Underwent eradication therapy with praziquantel. Clinical discussion: The finding of Schistosoma eggs in the gallbladder wall during routine histopathological examination highlights the importance of considering schistosomiasis, and other parasites, in cases of recurrent bouts of cholecystitis. The case challenges the conventional understanding of the transmission patterns of this parasitic infection and raises questions about potential atypical life cycle routes within the human body. It also emphasizes the importance of routine histopathology analysis of specimen removed from the body. Conclusion: This case report presents a rare occurrence of schistosomiasis cholecystitis in a 42-year-old female patient underscoring the importance of considering parasitic infections. Thorough histopathological examination in routine surgeries is crucial for early detection and targeted treatment. The patient\u27s positive response to praziquantel therapy highlights its effectiveness in managing schistosomiasis, which is a neglected tropical disease

Diagnostic challenges and management of choledochal cyst in an 11-year-old child: a delayed diagnosis (a case report)

Choledochal cyst are rare congenital disease of the biliary tree. It presenting as cystic dilatations of the biliary tree can involve the extrahepatic biliary radicles, the intrahepatic biliary radicles or both. They are typically a surgical problem of infancy and childhood, but less than a quarter of the patients the diagnosis is delayed until adulthood as it presenting with vague and nonspecific signs and symptoms. In a case with biliary symptoms, abdominal ultrasound scan is the initial imaging modality of choice. Precise and accurate delineation of the biliary system mandates cholangiography with the advantage of non-invasive magnetic resonance cholangiopancreatography (MRCP) over endoscopic retrograde cholangiopancreatography. A case report of 11-year-old Tanzania girl with abdominal swelling and jaundice presented to a health facility for evaluation. She complained of abdominal swelling that her mother noticed when she was 3 years old, located above the umbilicus and since then it was not changed its size until 8 years later when it rapidly increased in size associated with non-specific dull pain. Abdominal computed tomography (CT) scan was done showed A well-defined hypo-attenuated non-enhancing retro-gastric cyst. Percutaneous transhepatic cholangiopancreatography (PTC) was performed due to inconclusive findings from CT-scan showed extrahepatic huge cystic dilatation, dilated central right hepatic ducts, left intrahepatic ducts failed to be visualize. Diagnosis of choledochal cyst type isovaleric acidaemia (IVA) was made. Explorative laparotomy was done, huge cystic mass occupying common bile duct was seen below the liver with distended gallbladder covered with visceral peritoneum. Second part of duodenum, pancreases and transverse colon was adhered to the inferior surface of the mass that further make difficult for cyst excision and reconstruction. Cyst was decongested and cholangioenterostomy with Roue-en-Y reconstruction was made. Cholecystectomy was done, hemostasis archived abdomen closed and patient sent to Intensive care units (ICU). Despite of advanced diagnostic modalities, delayed diagnosis of choledochal cyst can be a challenge due to its vague and nonspecific signs and symptoms. Excision of the cyst and reconstruction by hepatojejunostomy as the standard therapy could be difficult due to its biliary complications such as adhesion and infection and hence cyst-enterostomy drainage procedure can be done as option for relief of patient discomfort and prevent further complications

A Comprehensive Overview of In-patients Treated for Hepatocellular Carcinoma at a Tertiary Care Facility in Tanzania

Hepatocellular carcinoma (HCC) is one of the commonest causes of cancer-related morbidity and mortality worldwide. However, only a limited number of studies on HCC have been conducted in Tanzania. We therefore conducted a cross-sectional study among in-patients treated for HCC in a tertiary referral hospital located in Dar es Salaam, Tanzania, in order to provide a concise description of the clinical characteristics and treatment options offered in the study setting. We identified 36 in-patients treated for HCC over a 6-month data collection period. Seventy-seven percent (n = 28) of the participants were males and about two-thirds (61.2%) were aged between 40 and 60 years. Majority (44.4% [n = 16]) of the patients had Child-Pugh class B and an Eastern Cooperative Oncology Group (ECOG) performance status of 2 (33.3% [n = 12]). Patients with tumors >6.5 cm and multinodular tumors (>3 nodules) accounted for 69.4% (n = 25) and 55.6% (n = 20), respectively. Portal vascular invasion and extrahepatic metastasis were respectively present in 27.8% (n = 10) and 25% (n = 9) of the patients. Of the study participants, only two had early-stage disease as per the Barcelona Clinic Liver Cancer (BCLC) staging system, corresponding to the observed tumor resection rate of 5.6%. The most frequently reported inoperable factor among the study participants was an ECOG performance status > 0 (n = 30 [83.3%]). Findings thus reveal a high proportion of late-stage diseases among participants that could have resulted in the observed low tumor resection rate. Initiatives to facilitate identification of the disease at an early stage are therefore paramount in optimizing care

Antibiotic use in urological surgeries: a six years review at Muhimbili National Hospital, Dar es salaam-Tanzania

Introduction: Antimicrobial prophylaxis for urologic procedures is a major issue, as potential   advantages of antibiotic administration should be carefully weighed against potential side effects,   microbial resistance, and health care costs. This study aimed to review a six years trend of antibiotic  use  in urological surgeries at Muhimbili National Hospital (MNH) being an experience in a typical third  world environment.Methods: This was a six years hospital based descriptive, retrospective study conducted of which all case notes of urological patients operated on in between January 2007 to December, 2012 were reviewed by using a structured data collecting tool. The data were analyzed using SPSS software.Results: Male patients were the majority at 62% (450). The age range was 0 - 90 years, with a mean of 30 ± 22.09. Among the urological surgeries done at MNH 86.5% (628) received prophylactic antibiotics  regardless of the type surgery done. Majority 63.7% (463) received antibiotics during induction.  Ceftriaxone was the commonly given antibiotic regardless of the type of urological surgery done. Most of patients (86.4%) were given antibiotics for five days regardless whether it was for prophylactic or  treatment intention.Conclusion: Antibiotic use is still a challenge at our hospital with over use of prophylactic antibiotics  without obvious indications. Prolonged use of prophylactic antibiotics beyond five days was the main finding. Ceftriaxone was the most given antibiotic regardless of the urological surgery done and its level of contamination. Antibiotic stewardship needs to be addressed urgently to avoid serious drug resistances leaving alone the cost implication.Key words: Antibiotics, urological surgeries, Tanzania

Adherence to Universal Precautions and Associated Factors among Nurses Caring For Critically Ill Patients in Dar es Salaam Tanzania

Background: Globally, it is known that heath care workers particularly in critical care settings are at higher risk of occupational exposure to infections. Surveillance systems to monitor body fluid exposure have been established in developed world. However, such systems are not available and consequently, exposure to body fluids is rarely reported, documented and monitored in many African countries. Objectives: To assess knowledge, practice and factors influencing adherence of Universal Precautions of infection prevention among nurses at Muhimbili national hospital and Muhimbili orthopaedic institute Dar es salaam Tanzania. Design: Quantitative cross-sectional and observational study. SPSS was used for data analysis. Chi-square test and student t-test were used for analysis of categorical and continuous variables respectively and regression analysis were done to determine any significance. Participants: 144 nurses in intensive care units, emergency rooms and recovery rooms were assessed using a structured self-administered questionnaire and an observational checklist to 42 of 144. Findings: 38% of nurses had good knowledge of universal precautions. 85% reported to always wash hands, however, 34.3% of participants were observed to wash hands before putting on gloves. 94.4% reported to always use gloves, 67.4% reported to always wear a gown and 55.6% reported that they always wear a mask. Regarding sharps management 93.8% reported good practice and 95.2% demonstrated good sharps management practice. Sex and level of education of an individual significantly influenced the hand hygiene practice, working station and perceived severity significantly influenced the practice of wearing protective gear. Training on infection prevention and control significantly influenced sharps handling (All p\u3c0.05). Discussion: Adherence of universal precautions were sub optimal. Reported and observed practice were incompatible as in other studies except in the practice of sharps management which observed results outweighed the reported results. Conclusion: Adherence to universal precaution is variably poor. Surveillance systems to monitor exposures to body fluids is requir

Detection of malaria parasites in dried human blood spots using mid-infrared spectroscopy and logistic regression analysis

Background: Epidemiological surveys of malaria currently rely on microscopy, polymerase chain reaction assays (PCR) or rapid diagnostic test kits for Plasmodium infections (RDTs). This study investigated whether mid-infrared (MIR) spectroscopy coupled with supervised machine learning could constitute an alternative method for rapid malaria screening, directly from dried human blood spots. Methods: Filter papers containing dried blood spots (DBS) were obtained from a cross-sectional malaria survey in 12 wards in southeastern Tanzania in 2018/19. The DBS were scanned using attenuated total reflection-Fourier Transform Infrared (ATR-FTIR) spectrometer to obtain high-resolution MIR spectra in the range 4000 cm−1 to 500 cm−1. The spectra were cleaned to compensate for atmospheric water vapour and CO2 interference bands and used to train different classification algorithms to distinguish between malaria-positive and malaria-negative DBS papers based on PCR test results as reference. The analysis considered 296 individuals, including 123 PCR-confirmed malaria positives and 173 negatives. Model training was done using 80% of the dataset, after which the best-fitting model was optimized by bootstrapping of 80/20 train/test-stratified splits. The trained models were evaluated by predicting Plasmodium falciparum positivity in the 20% validation set of DBS. Results: Logistic regression was the best-performing model. Considering PCR as reference, the models attained overall accuracies of 92% for predicting P. falciparum infections (specificity = 91.7%; sensitivity = 92.8%) and 85% for predicting mixed infections of P. falciparum and Plasmodium ovale (specificity = 85%, sensitivity = 85%) in the field-collected specimen. Conclusion: These results demonstrate that mid-infrared spectroscopy coupled with supervised machine learning (MIR-ML) could be used to screen for malaria parasites in human DBS. The approach could have potential for rapid and high-throughput screening of Plasmodium in both non-clinical settings (e.g., field surveys) and clinical settings (diagnosis to aid case management). However, before the approach can be used, we need additional field validation in other study sites with different parasite populations, and in-depth evaluation of the biological basis of the MIR signals. Improving the classification algorithms, and model training on larger datasets could also improve specificity and sensitivity. The MIR-ML spectroscopy system is physically robust, low-cost, and requires minimum maintenance

Characterization of hormonal receptors and human epidermal growth factor receptor-2 in tissues of women with breast cancer at Muhimbili National Hospital, Dar es salaam, Tanzania

Abstract Background Breast cancer is a leading cause of morbidity and deaths among women worldwide. In Tanzania there is no published data on human epidermal growth receptor-2 (HER2/neu) expression in breast carcinoma. Hormonal receptors and HER2/neu status reportedly influence post-mastectomy adjuvant therapy and predict treatment outcome and prognosis. Here we evaluate hormonal receptors and HER-2 status in biopsies of women with breast cancer at Muhimbili National Hospital (MNH). Methods A cross-sectional study of female breast post-modified radical mastectomy (MRM)/incisional biopsies confirmed to be carcinoma at the Histopathology Unit (January–December 2013). Tissue blocks having poor morphology, without tumor, secondary tumors, cases outside the study period and male patients were excluded. Routine staining was done followed by immunohistochemistry for estrogen (ER), and progesterone (PgR) receptors and HER2. Data analyzed using Statistical Package for Social Sciences (SPSS). Results A total of 218 cases were confirmed to be carcinoma including 70 meeting inclusion criteria. Age at diagnosis ranged 18–75 years and mean age was 48.36 years. Majority (64.3%) were in the 36–55 years age-group. Histologically, most (88.6%) women had invasive ductal carcinoma including 43.1% of intermediate grade. A great majority (78%) were stage three. Due to logistical constrains, 75.7% (n = 53/70) cases where immunostained for hormones including 43.4% (ER+), 26.4% (PgR+), and 28% (ER+/PgR+). Furthermore, 65.7% (n = 46/70) cases were immunostained for HER-2 and 15.2% (n = 7/46) were positive, 45.6% were triple negative (ER-,PgR-,HER2-), 23.9% (ER+,PgR+,HER2-) or luminal B, 2.2% (ER+,PgR-,HER2+),13% (ER-,PgR-,HER2+) and 15% (ER+,PgR-,HER2-) with none being triple positive. Conclusions Hormonal receptors and HER2 expression at MNH appears to be comparable to previous Africans/African Americans reports but not with studies among Caucasians and the current proportion of triple negative breast carcinomas (TNBC) is higher than in a previous Tanzanian report and majority are luminal. HER2 over-expression is relatively common. It is strongly recommended that receptor status assessment be made routine for breast cancer patients at MNH

Prolonged retention of gauze sponge resulting in ileocolic fistula, a rare complication following cesarean section; case report

Introduction and importance Retained gauze sponge is a medical legal issue with significant clinical implications with catastrophic complications. We report a case of a female who presented with chronic right iliac fossa pain only to be found to have a retained gauze sponge causing bowel fistulisation. We describe our experience on diagnostic formulation and work up and subsequent operative intervention. Case presentation We present the case of a 37-year-old female patient who presented to the outpatient surgical department with symptoms of chronic right iliac fossa pain with a history of cesarean section 2 years prior. A computed tomography scan revealed an inflammatory mass and operative exploration revealed a retained gauze sponge causing a fistula between the terminal ileum and caecum. Underwent a right hemicolectomy with an uneventful postoperative period. Clinical discussion Retained gauzes can lead to a spectrum of complications including fistulisation presenting with vague non-specific abdominal symptoms. The subtle presentation challenges the clinician to consider the possibility of retained foreign bodies in patient with history of abdominal surgeries. This emphasizes the importance of policies enforcing swab count as a simple retained gauze led to catastrophic complication and ultimately a right hemicolectomy. Conclusion This case report presents a complex and instructive clinical scenario, emphasizing the challenges of diagnosing atypical presentations of retained foreign bodies, the critical importance of surgical counting protocols, and the implications for patient safety and quality of care
