Giant ovarian cysts are tumours of the ovary presenting with diameters greater than 10 cm. Giant ovarian cysts have become rare in recent days as they are diagnosed and managed early due to the availability of good imaging modalities. The aim of this case report is to show how a huge cystic ovarian mass can mislead the diagnosis of ascites in a postmenopausal woman. Factors associated with late presentation of giant ovarian cysts in sub-Saharan Africa have also been discussed. We present the case of a 65-year-old grand multiparous woman who was referred to our centre with a grossly distended abdomen misdiagnosed as a massive ascites. Abdominopelvic ultrasound scan revealed a right giant multiloculated ovarian cyst. She benefited from a cystectomy with an uneventful postoperative stay. Histopathology revealed mucinous cystadenoma. Large cystic ovarian tumours can present masquerading as massive ascites and misleading diagnosis as in this case report. We report this case to increase the suspicion index of a large ovarian cyst in all women presenting with massive ascites.

Medical and nursing students in Cameroon are likely to have mental health problems given the stressful nature of their studies. Paucity of mental health institutions in the country implies they hardly get access to professional help when needed and are obliged to develop coping strategies such as recreational drug use. This study aims to determine the prevalence and predictors of recreational drug use among a group of Cameroonian medical and nursing students. Cross-sectional analysis of 852 medical and nursing students (mean age 21.78 ± 3.14, 31.49% males) recruited by convenience sampling from three state-owned medical schools; and from two state-owned and two private nursing schools in Cameroon over a four-month period (January–April 2018). Information was collected via a printed self-administered and structured questionnaire from consenting students. Multivariable logistic regression analysis was used to identify independent predictors of recreational drug use. The overall prevalence of recreational drug use was 1.64% with tramadol and marijuana noted as the drugs used by these students. Independent predictors of recreational drug use were: presence of a chronic illness (OR 5.26; 95% CI 1.32, 20.97; p = 0.019), alcohol consumption (OR 5.08; 95% CI 1.54, 16.73; p = 0.008) and Total Oldenburg Burnout Inventory score (OR 1.11; 95% CI 1.02, 1.21; p = 0.021). The use of recreational drugs by medical and nursing students in Cameroon remains worrisome despite its very low prevalence, as it may negatively impact their performance and health.

Tropical diabetic hand syndrome describes a complex hand sepsis affecting patients with diabetes across the tropics and often results from a trivial hand trauma. The clinical presentation of this syndrome is variable and ranges from localised swelling and cellulitis, with or without ulceration of the hand to progressive fulminant hand sepsis, and gangrene affecting the entire limb which may be fatal. Tropical diabetic hand syndrome could lead to permanent disability and death as a result of delay in presentation, late diagnosis and late medical and surgical intervention. This indexed case acts as an eye opener for physicians to the existence of this hand sepsis. We report the case of a 57 year-old black African female diabetic who was referred to our centre for the management of a suppurating ulcer and swelling of the left hand of two weeks duration. On examination and work-up, the patient was found to have Lawal Group III left diabetic hand syndrome and was managed with parenteral antibiotics, radical debridement and the hand was eventually amputated. She died 7 days following amputation from overwhelming sepsis. Though tropical diabetic hand syndrome is a relatively rare complication of diabetes, it can be fatal as in this case report. Early diagnosis and proper management would yield better outcome. Initial management should include aggressive intravenous broad-spectrum antibiotics with anaerobic coverage. Classification of tropical diabetic hand syndrome will assist physicians and surgeons in decision making, proper management and easy communication.

Hydroquinone-containing creams cause false increases in capillary glycemia. However, the magnitude of this false increase, and the means to reverse it have not been investigated. To evaluate the technical and clinical impact of hydroquinone-containing creams on capillary glycemia and investigate the efficacy of hand washing and other common practices, in reversing cream effects. We included 91 participants in a quasi-experimental study in Buea, Cameroon. After determining the hydroquinone content of a cream, Caro Light, we used two glucometers with different enzymatic systems (Accu-Chek Active and OneTouch Ultra 2) to measure fasting glycemia after: initial hand washing (reference), application of 1 ml of hydroquinone-containing cream, finger swabbing with wet gauze, sanitizer application and a series of three hand washings following cream application. Reference glycemia was compared to those obtained after various interventions. Statistical significance was assessed by paired sample t-test, clinical significance by total error allowable (TEa), and clinical impact by Parke’s error grid analysis. The mean differences in capillary glycemia (Intervention—reference) measured by Accu-Chek Active in mg/dl were 28, 27, 38, 16, 4, and -2 after cream application, finger swabbing, sanitizer application, one, two, and three hand washings respectively. Corresponding values for OneTouch Ultra2 were 41, 44, 64, 22, 5 and -5. These differences, except after two and three hand washings were both statistically (p < 0.0001) and clinically significant (TEa). After cream application, Accu-Check had 9.9% of values in Parke’s Zones C-E, while OneTouch had 18.7%. Hydroquinone-containing creams cause significant false increase in capillary glycemia irrespective of the enzymatic system of the glucometer used, and can lead to potentially wrong clinical decisions. A minimum of two hand washings is required prior to capillary glucose measurement.

Necrotizing fasciitis is a rare soft tissue infection characterized by rapid progressive necrosis with relative sparing of underlying muscles. This case is reported to highlight the emergence of multidrug resistant microbes in recent days which limits the use of empiric antibiotic therapy and necessitates early cultures and sensitivity enabling targeted antibiotic therapy. Factors that lead to antimicrobial resistance especially in sub-Saharan Africa have also been discussed. We report the case of a 52-year-old black man who was referred to our centre for the management of cellulitis and suppurating ulcers of the right leg which had progressed to a wet gangrene. Following physical examination and work-up, a diagnosis of fulminant necrotizing fasciitis of the right leg caused by multidrug resistant Proteus mirabilis and Escherichia coli was made. Despite the broad-spectrum empiric antibiotic therapy and aggressive multiple surgical debridement, necrosis progressed leading to an above-knee amputation. Necrotizing fasciitis is a surgical emergency that requires prompt diagnosis and aggressive surgical debridement in order to reduce morbidity and mortality. The emergence of multidrug resistant organisms in recent days have limited the use of empiric antibiotic therapy, necessitating early culture and sensitivity and the use of susceptibility-guided antibiotic therapy. Timely action to control the use of antibiotics in sub-Saharan Africa will reduce multidrug resistance and delay the arrival of post-antibiotics era.

Emergency medical services with pre-hospital care remain poorly developed in sub-Saharan Africa and the developing world at large. The provision of timely treatment during life-threatening emergencies is not a priority for many health systems in developing countries. In this review, the authors reviewed the evidence indicating the need to develop and/or strengthen emergency medical care systems in sub-Sahara Africa with perspectives drawn from Cameroon.
