Perioperative serum albumin as a predictor of adverse outcomes in abdominal surgery: prospective cohort hospital based study in Northern Tanzania.

BACKGROUND: Albumin is an important protein that transports hormones, fatty acids, and exogenous drugs; it also maintains plasma oncotic pressure. Albumin is considered a negative active phase protein because it decreases during injuries and sepsis. In spite of other factors predicting surgical outcomes, the effect of pre and postoperative serum albumin to surgical complications can be assessed by calculating the percentage decrease in albumin (delta albumin). This study aimed to explore perioperative serum albumin as a predictor of adverse outcomes in major abdominal surgeries. METHODS: All eligible adult participants from Kilimanjaro Christian Medical Centre Surgical Department were enrolled in a convenient manner. Data were collected using a study questionnaire. Full Blood Count (FBP), serum albumin levels preoperatively and on postoperative day 1 were measured in accordance with Laboratory Standard Operating Procedures (SOP). Data was entered and analyzed using STATA version 14. Association and extent of decrease in albumin levels as a predictor of surgical site infection (SSI), delayed wound healing and death within 30 days of surgery was determined using ordinal logistic regression models. In determining the diagnostic accuracy, a Non-parametric Receiver Operating Curve (ROC) model was used. We adjusted for ASA classification, which had a negative confounding effect on the predictive power of the percent drop in albumin to adverse outcomes. RESULTS: Sixty one participants were studied; the mean age was 51.6 (SD16.3), the majorities were males 40 (65.6%) and post-operative adverse outcomes were experienced by 28 (45.9%) participants. In preoperative serum albumin values, 40 (67.8%) had lower than 3.4 g/l while 51 (91%) had postoperative albumin values lower than 3.4 g/l. Only 15 (27.3%) had high delta albumin with the median percentage value of 14.77%. Delta albumin was an independent significant factor associated with adverse outcome (OR: 6.68; 95% CI: 1.59, 28.09); with a good predictive power and area under ROC curve (AUC) of 0.72 (95% CI 0.55 0.89). The best cutoff value was 11.61% with a sensitivity of 76.92% and specificity of 51.72%. CONCLUSION: Early perioperative decreases in serum albumin levels may be a good, simple and cost effective tool to predict adverse outcomes in major abdominal surgeries.

Patterns and outcomes of patients with abdominal trauma on operative management from northern Tanzania: a prospective single centre observational study.

BACKGROUND: The abdomen is one of the most commonly injured regions in trauma patients. Abdominal injury surgeries are common in Tanzania and in many parts of the world. This study aimed to determine the relationships among the causes, characteristics, patterns and outcomes of abdominal injury patients undergoing operations at Kilimanjaro Christian Medical Centre. METHODS: A prospective observational study was performed over a period of 1 year from August 2016 to August 2017. A case was defined as a trauma patient with abdominal injuries admitted to the general surgery department and undergoing an operation. We assessed injury types, patterns, aetiologies and outcomes within 30 days. The outcomes were post-operative complications and mortality. Multivariate logistic regression was used to explore the association between factors associated with morbidity and mortality. RESULTS: Out of 136 patients, 115 (84.6%) were male, with a male-to-female ratio of 5.5:1. The most affected patients were in the age range of 21-40 years old, which accounted for 67 patients (49.3%), with a median age (IQR) of 31.5 (21.3-44.8) years. A majority (99 patients; 72.8%) had blunt abdominal injury, with a blunt-to-penetrating ratio of 2.7:1. The most common cause of injury was road traffic accidents (RTAs; 73 patients; 53.7%). Commonly injured organs in blunt and penetrating injuries were, respectively, the spleen (33 patients; 91.7%) and small bowel (12 patients; 46.1%). Most patients (89; 65.4%) had associated extra-abdominal injuries. Post-operative complications were observed in 57 patients (41.9%), and the mortality rate was 18 patients (13.2%). In the univariate analysis, the following were significantly associated with mortality: associated extra-abdominal injury (odds ratio (OR): 4.9; P-value< 0.039); head injury (OR: 4.4; P-value < 0.005); pelvic injury (OR: 3.9; P-value< 0.043); length of hospital stay (LOS) ≥ 7 days (OR: 4.2; P-value < 0.022); severe injury on the New Injury Severity Score (NISS) (OR: 21.7; P-value < 0.003); time > 6 h from injury to admission (OR: 4.4; P-value < 0.025); systolic BP < 90 (OR: 3.5; P-value < 0.015); and anaemia (OR: 4.7; P-value< 0.006). After adjustment, the following significantly predicted mortality: severe injury on the NISS (17 patients; 25.8%; adjusted odds ratio (aOR): 15.5, 95% CI: 1.5-160, P-value < 0.02) and time > 6 h from injury to admission (15 patients; 19.2%; aOR: 4.3, 95% CI: 1.0-18.9, P-value < 0.05). CONCLUSION: Blunt abdominal injury was common and mostly associated with RTAs. Associated extra-abdominal injury, injury to the head or pelvis, LOS ≥ 7 days, systolic BP < 90 and anaemia were associated with mortality. Severe injury on the NISS and time > 6 h from injury to admission significantly predicted mortality.

Colorectal cancer in a patient with intestinal schistosomiasis: a case report from Kilimanjaro Christian Medical Center Northern Zone Tanzania.

BACKGROUND: Colorectal cancer associated with chronic intestinal schistosomiasis has been linked with the chronic inflammation as a result of schistosomal ova deposition in the submucosal layer of the intestine. Among all species Schistosoma japonicum has been more linked to development of colorectal cancer as compared to Schistosoma mansoni due to absence of population-based studies to support the association. Despite the weak evidence, some cases have been reported associating S. mansoni with development of colorectal cancer. CASE PRESENTATION: We report a patient who presented to us as a case of intestinal obstruction and found to have a constrictive lesion at the sigmoid colon at laparotomy, then later found to have colorectal cancer with deposited S. mansoni ova at histology. CONCLUSION: Given the known late complications of schistosomiasis, and as S. mansoni is endemic in some parts of Tanzania, epidemiological studies are recommended to shed more light on its association with colorectal cancer.

The effect of social integration on outcomes after major lower extremity amputation.

OBJECTIVE: Major lower extremity (MLE) amputation is a common procedure that results in a profound change in a patient's life. We sought to determine the association between social support and outcomes after amputation. We hypothesized that patients with greater social support will have better post amputation outcomes. METHODS: From November 2011 to May 2013, we conducted a cross-sectional, observational, multicenter study. Social integration was measured by the social integration subset of the Short Form Craig Handicap Assessment and Reporting Technique. Systemic social support was assessed by comparing a United States and Tanzanian population. Walking function was measured using the 6-minute walk test and quality of life (QoL) was measured using the EuroQol-5D. RESULTS: We recruited 102 MLE amputees. Sixty-three patients were enrolled in the United States with a mean age of 58.0. Forty-two (67%) were male. Patients with low social integration were more likely to be unable to ambulate (no walk 39% vs slow walk 23% vs fast walk 10%; P = .01) and those with high social integration were more likely to be fast walkers (no walk 10% vs slow walk 59% vs fast walk 74%; P = .01). This relationship persisted in a multivariable analysis. Increasing social integration scores were also positively associated with increasing QoL scores in a multivariable analysis (ß, .002; standard error, 0.0008; P = .02). In comparing the United States population with the Tanzanian cohort (39 subjects), there were no differences between functional or QoL outcomes in the systemic social support analysis. CONCLUSIONS: In the United States population, increased social integration is associated with both improved function and QoL outcomes among MLE amputees. Systemic social support, as measured by comparing the United States population with a Tanzanian population, was not associated with improved function or QoL outcomes. In the United States, steps should be taken to identify and aid amputees with poor social integration.

From penetrating abdominal injury to enterocutaneous fistula, a deadly outcome: A case report.

Enterocutaneous fistula is a dreaded complication by most surgeons especially after emergency abdominal surgery. It can also occur spontaneously from an underlying disease. The pathology is demanding both mentally and physically and causes medical and nursing problems for the affected individual. In this case report we present a timeline of a young 4-year-old boy who sustained penetrating abdominal-perineal injury from a fall and later presented with peritonitis. His condition progressed to complicate into enterocutaneous fistula and succumbed unfortunately due to multifactorial reasons. This shows the impact and burden of the disease pathology not only on patients but also on the medical system as a whole.

Prevalence of Multidrug Resistant UTI Among People Living with HIV in Northern Tanzania.

BACKGROUND: Bacterial urinary tract infection (BUTI) is the commonest urinary tract infection among people living with human immunodeficiency virus (PLHIV). It causes significant morbidity in this vulnerable group. Immunosuppression due to HIV can mask the signs and symptoms of infection leading to asymptomatic disease. There is limited evidence in Tanzania regarding BUTI and PLHIV. This study aimed to determine the prevalence, etiology, risk factors and susceptibility pattern of isolates causing asymptomatic UTI in PLHIV at Kilimanjaro Christian Medical Centre (KCMC). PATIENTS AND METHODS: This cross-sectional study was conducted from July to September 2020 at Kilimanjaro Christian Medical Centre (KCMC) hospital. A questionnaire was used to collect social demographic data from patients' files together with necessary information required by this study. Urine samples were obtained from participants for urinalysis and urine culture and sensitivity. Data from 300 adults aged ≥18 years were analyzed using Statistical Package for Social Science (SPSS) version 22. Mean or median with their measure of dispersion were calculated for continuous variables. Logistic regression was used to determine associations between variables, where P-value <0.05 was considered to be significant. RESULTS: Bacteriuria was prevalent in 37 (12.3%) of PLHIV. Positive nitrite in urine was associated with bacteriuria (P = 0.01). Gram-positive bacteria were the most common 25 (67.6%) isolates with high sensitivity to nitrofurantoin (88.2%) followed by gentamycin (69.2%). However, resistance was high against ciprofloxacin (77.8%). Multidrug resistance (MDR) was noted in 17 (45.9%). CONCLUSION: One in eight of PLHIV attending CTC at KCMC referral hospital in Northern zone of Tanzania have BUTI. Presence of nitrites in urine is an important biomarker associated with BUTI. About two third of the isolates were Gram-positive bacteria, and nearly half of all isolates showed MDR to commonly used antibiotics.

Schistosomiasis and cancer: Experience from a zonal hospital in Tanzania and opportunities for prevention.

Schistosomiasis infection is endemic in many parts of Tanzania. The morbidity due to Schistosomiasis and its association with cancer remains to be of great concern and poses greater challenge that needs to be assessed. Cancer is an increasing public health problem in most sub-Saharan African countries, and yet, cancer control programs and the provision of early detection and treatment services are limited despite this increasing burden. This article aims to discuss case series of patients diagnosed with urinary bladder, prostate and colorectal cancer together with Schistosoma infection. We further highlight the opportunities for combating new Schistosomiasis infection, a potential to reduce its oncological complications particularly in low-resource setting.

Colorectal Cancer in Northern Tanzania: Increasing Trends and Late Presentation Present Major Challenges.

PURPOSE: A trend of increasing incidence of colorectal cancer (CRC) has been observed in northern Tanzania. Studies have shown a six-fold increase in CRC in the past decade, with 90% of patients presenting in late stages, with resultant high morbidity and mortality rates. In this study, we aimed to document the burden of CRC in the northern zone of Tanzania from 1998 to 2018, focusing on patient presentation, clinical features, and treatment at a tertiary hospital. METHODS: Pathological and clinical records for all patients from 1998 to 2018 were identified and reviewed. Records of patients whose CRC was diagnosed histologically were retrospectively reviewed. RESULTS: Approximately 313 CRC cases were documented. The majority age group (29.1%) was between 50 and 64 years (mean [standard deviation], 54.28 [16.75] years). However, together, the age groups of patients younger than 50 years was 41.5% (n = 130). Of 174 patients with complete records, most (29.3%) were between 35 and 49 years of age. The median age was 52 (interquartile range, 40-67) years. Men accounted for 62.1% of patients and were mostly from the Kilimanjaro region. More than half (54.7%) presented > 3 months after symptom debut; 62.6% first sought care at lower-level health facilities. Most (64.9%) presented as emergencies, necessitating colostomy for fecal diversion as the initial surgical procedure in 60.3% of patients. Colonoscopy was performed for 38.6% of the study participants. Most tumors (72.7%) originated from the sigmoid and rectum. Adenocarcinoma was the most prevalent histologic type. CONCLUSION: High proportions of young individuals with CRC pose great concern and a need for further appraisal. Furthermore, late emergency presentation and low colonoscopy rates highlights underlying system challenges and need for education campaigns.

Isolated Pulmonary Hydatid Cyst: A Rare Presentation in a Young Maasai Boy from Northern Tanzania.

INTRODUCTION: Hydatidosis is a parasitic manifestation caused by Echinococcus granulosus. It is characterized by cystic lesions in the liver and lungs. Diagnosis is based on typical history and radiological measures. CASE PRESENTATION: A four-year-old boy presented with a one-year history of dry cough and difficulty in breathing which was of gradual progression. Computed tomography of the chest revealed a large 11.7 cm × 8.6 cm × 11.0 cm cyst in the right hemithorax. The patient underwent thoracotomy and recovered well post procedure. CONCLUSION: This case report highlights that large hydatid cysts can be surgically removed with good outcome and the importance of realizing that the disease is a burden to the public health and is much neglected.

Tubular Duplication of the Midgut Presenting with Acute Abdomen and Hematochezia: A Case Report from Northern Tanzania.

Enteric duplication is one of the rare malformations affecting the small intestine more than the other parts of the gastrointestinal tract. It poses a challenge in diagnosis due to nonspecific symptoms that may mimic other pathologies. Furthermore, the management options including total resection, mucosal striping, and internal drainage of the duplicate depend on the presentation of the patient, site, and length of the involved bowel. We present the first documented case of enteric duplication in Tanzania, a 3-year-old male, who was found to have a 90 cm long jejunoileal duplicate. We discuss the presentation and management offered.
