Evaluating the potential impact of a mobile telemedicine system on coordination of specialty care for patients with complicated oral lesions in Botswana.

Mobile telemedicine involves the use of mobile device (e.g., cell phones, tablets) technology to exchange information to assist in the provision of patient care. Throughout the world, mobile telemedicine initiatives are increasing in number and in scale, but literature on their impact on patient outcomes in low-resource areas is limited. This study explores the potential impact of a mobile oral telemedicine system on the oral health specialty referral system in Botswana. Analysis of 26 eligible cases from June 2012 to July 2013 reveals high diagnosis concordance between dental officers and oral health specialists at 91.3% (21/23) but significant management plan discordance at 64.0% (16/25), over two-thirds of which involved the specialists disagreeing with the referring clinicians about the need for a visit to a specialist. These findings suggest mobile telemedicine can optimize the use of insights and skills of specialists remotely in regions where they are scarce.

Oncogenic viral prevalence in invasive vulvar cancer specimens from human immunodeficiency virus-positive and -negative women in Botswana.

OBJECTIVE: The primary aim of this study was to describe the prevalence of select oncogenic viruses within vulvar squamous cell carcinoma (VSCC) and their association with human immunodeficiency virus (HIV) status in women in Botswana, where the national HIV prevalence is the third highest in the world. METHODS: A cross-sectional study of biopsy-confirmed VSCC specimens and corresponding clinical data was conducted in Gaborone, Botswana. Polymerase chain reaction (PCR) and immunohistochemistry (IHC) viral testing were done for Epstein-Barr virus, human papillomavirus (HPV) strains, and Kaposi sarcoma herpesvirus, and PCR viral testing alone was done for John Cunningham virus. RESULTS: Human papillomavirus prevalence by PCR was 100% (35/35) among tested samples. Human papillomavirus type 16 was the most prevalent HPV strain (82.9% by PCR, 94.7% by either PCR or IHC). Kaposi sarcoma herpesvirus prevalence by PCR had a significant association with HIV status (P = 0.013), but not by IHC (P = 0.650). CONCLUSIONS: The high burden of HPV, specifically HPV16, in vulvar squamous cell cancer in Botswana suggests a distinct HPV profile that differs from other studied populations, which provides increased motivation for HPV vaccination efforts. Oncogenic viruses Kaposi sarcoma herpesvirus and Epstein-Barr virus were also more prevalent in our study population, although their potential role in vulvar squamous cell cancer pathology is unclear.

Evaluating the impact of a mobile oral telemedicine system on medical management and clinical outcomes of patients with complicated oral lesions in Botswana.

Mobile telemedicine, which involves the use of cellular phone telecommunications to facilitate exchange of information between parties in different locations to assist in the management of patients, has become increasingly popular, particularly in resource-limited settings. In Botswana, small studies of mobile telemedicine programs suggest access to these services positively affect patients, but these programs' impact is difficult to capture given limitations of baseline and comparative data. Our observational study uses each patient receiving mobile oral telemedicine services in Botswana as his/her own control to assess the impact of these services on his/her diagnosis and management plan. At month 5 of 12 total, preliminary analysis of eligible cases (n = 27) reveals management plan discordance between clinicians submitting cases and the specialist was 68.0% (17/25), suggesting that telemedicine can result in significant changes in management of patients.
