Outcomes of interventions to optimize linkage to HIV care and antiretroviral therapy (ART) initiation after HIV self-testing: A scoping review.

Background: Human immunodeficiency virus (HIV) self-testing is an innovative solution to the problem of low HIV testing coverage. It can help in realizing the first "95" of the Joint United Nations Programme on HIV/AIDS targets in the HIV treatment cascade. However, there is limited information to guide how those who self-test and show positive results can successfully be linked to HIV care and treatment. Therefore, this scoping review aimed at synthesizing available evidence of the outcomes of intervention strategies to optimize linkage to HIV care after HIV self-testing. Methods: Our methodology followed Arksey and O'Malley's methodological framework. Two independent reviewers screened and extracted data based on predetermined criteria. The databases searched included PubMed, EBSCOhost, Web of Science, Cochrane Library, Scopus, Mednar, and the International Clinical Trials Registry Platform. Results: A total of 4809 records were retrieved. After full-text screening, 14 studies met the inclusion criteria for the review. The intervention strategies reported were classified into four main categories: technology-assisted interventions, innovative HIV self-testing kits distribution mechanisms, financial incentive, social entrepreneurship models, and the use of key community opinion leaders and social media influencers. This scoping review found men who have sex with men as the main recipients of the interventions to improve the rate of linkage to HIV care following HIV self-testing. Studies that met the inclusion criteria reported mixed findings on the outcomes of interventions to improve the rate of linkage to HIV care following HIV self-testing. Financial incentives, interventions leveraging technology, and key opinion leaders were the most effective strategies. Conclusions: Given that the included studies did not employ a uniform system of measurement of effectiveness, there is a need for identification of standardized definitions and clear indicators for evaluating linkage to care and antiretroviral therapy (ART) initiation following HIV self-testing.

Multidrug resistant Proteus mirabilis and Escherichia coli causing fulminant necrotising fasciitis: a case report.

BACKGROUND: 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. CASE PRESENTATION: 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. CONCLUSION: 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.

Effects of hydroquinone-containing creams on capillary glycemia before and after serial hand washings in Africans.

BACKGROUND: 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. OBJECTIVE: 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. METHODS: 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. RESULTS: 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%. CONCLUSION: 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.

Giant ovarian cyst masquerading as a massive ascites: a case report.

BACKGROUND: 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. CASE PRESENTATION: 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. CONCLUSION: 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.

Tropical diabetic hand syndrome: a case report.

BACKGROUND: 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. CASE PRESENTATION: 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. CONCLUSION: 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.
