Factors associated with mortality in patients with tetanus in Cameroon.

BACKGROUND: Tetanus constitutes a significant cause of death in sub-Saharan Africa, with case fatality rates as high as 64%, 47%, and 43.1% reported in Nigeria, Uganda, and Tanzania, respectively. However, the knowledge gap on factors that influence tetanus mortality still exists in Cameroon. OBJECTIVE: To identify the factors that influence the mortality of tetanus patients in three regional hospitals in the North West and South West Regions of Cameroon. METHODOLOGY: This was a 7-year retrospective case-series study. Socio-demographic and clinical data of tetanus cases admitted in Bamenda, Buea, and Limbe Regional Hospitals from January 2010 to March 2017 were collected and analysed. RESULTS: This study recorded 38 cases, but excluded five due to missing inpatient files. Of the 33 cases considered in this study, 27 (81.8%) were males. The mean age of the patients was 32 years. A tetanus mortality rate of 48.5% was recorded - thus, 16 tetanus-related deaths. Mortality was higher amongst patients with incubation periods less than 7 days; the onset of trismus and generalized spasms less than 8 days after exposure; the presence of autonomic dysfunction; the presence of respiratory dysfunction; application or introduction of local regimens, soil or animal waste at the portal of entry; delayed debridement greater than 2 days after onset of tetanus; and a severe clinical disease state. CONCLUSION: This study, therefore, highlights the need to ensure universal vaccination coverage for high-risk populations; males, active population (20-40 years), and farmers. More still, this study emphasizes the need to improve access and utilisation of mechanical ventilation in severe tetanus cases.

Clinical profile and management of primary thyroid cancer in patients with nodular goitre at the Douala General Hospital, Cameroon.

INTRODUCTION: thyroid cancer (TC) is considered to have become the fastest growing cancer in terms of incidence worldwide. Despite literature reporting a prevalence of 5-10% in clinically identified thyroid nodules, Cameroon still has limited data on the profile of TCs in patients with Nodular Goitres (NGs). The Objective were to describe the epidemiological, diagnostic and therapeutic profiles of TCs in patients with nodular goitres at the Douala General Hospital (DGH). METHODS: this was a retrospective cross-sectional analysis of patient records with diagnoses of NGs, over 11 years (2006 to 2016) at the DGH. RESULTS: overall, 187 patients (mean age= 46.8±13.9 years, men=27 (14.4%)) were included; 43 (23%) cancers were identified. The most common histological type was papillary cancer (50%). Nodule size of >4cm and hypoechogenicity were independently associated with malignancy. Most patients presented with TNM stage II (47.4%) and well-differentiated cancers were considered to be predominantly at low-risk according to MACIS (55%) and AMES (74%) scores. Surgery was offered to 95.3% of patients. CONCLUSION: TCs are frequent in patients with NGs with papillary cancer dominating. A high index of suspicion should be held if a nodule is >4cm and/or is hypoechogenic. Prognostic studies are needed to describe the outcome of TCs in our setting.

Incidence, risk factors, clinical presentation and treatment of ectopic pregnancy in the Limbe and Buea Regional Hospitals in Cameroon

Introduction: ectopic pregnancy (EP) is the leading cause of maternal mortality in the first trimester of pregnancy in our environment. This study aimed at evaluating the incidence, risk factors, clinical presentation and treatment of ectopic pregnancy in the Limbe and Buea Regional Hospitals in Cameroon. Methods: this was a retrospective nested case control study carried out from December 2006 to December 2016. A ratio for control vs cases of 3:1 was obtained. Any pregnancy implanted outside the normal uterine cavity was considered as an ectopic pregnancy. Student's t-test was used to compare continuous variables and Pearson's Chi-square test for categorical variables. The association between EP and the demographical and clinical variables was estimated using logistic regression. Statistical significance was set at p-values<0.05.Results: a total of 247 cases of EP were registered out of 17221 deliveries giving an incidence of 1.43% in ten years. History of pelvic inflammatory disease (OR = 3.10, CI (1.76-5.44), p < 0.001), previous EP (OR = 10.22, CI (2.61-14.82), p < 0.001), History of induced abortion (OR = 2.68, CI (3.32-9.73), p< 0.001), history of adnexa surgery (OR = 4.37, CI (2.17-10.32), p < 0.001) and history of appendectomy (OR = 2.16, CI (0.99-6.64) p< 0.001), were also found to be associated with increased risk of EP. More than five percent (5.52%) of the patients were in shock at presentation. Diagnosis was confirmed mainly by use of ultrasound (78.53%) and treatment was principally by laparotomy (97.55%) with salpingectomy (95.60%). Most (90.18%) of ectopic pregnancies were ruptured at presentation. Only 2.45% of cases were manage medically with the use of methotrexate. Conclusion: the incidence of ectopic pregnancy (EP) in our environment is within the global range (hospital-based incidence of 1.43%) and is rising. Late presentation, lack of modern diagnostic and management tools have made laparotomy with salpingectomy the principal method of management of ectopic pregnancy in our environment
