A Double Blind, Placebo Controlled, Randomized Trial to Evaluate the Efficacy and Tolerability of On-Demand Oral Pregablin (150 mg and 75 mg) in Treatment of Premature Ejaculation.

INTRODUCTION: Although premature ejaculation (PE) is a common sexual dysfunction, the available options for PE treatment remain unsatisfactory. AIM: To evaluate the effect of on-demand oral pregabalin on the intravaginal ejaculation latency time (IELT). METHOD: We conducted a multiarm double-blinded placebo-controlled randomized clinical trial that enrolled 120 patients with PE who were divided equally into 3 groups (A, B, and C). 4 patients were excluded, 39 patients received 150 mg pregabalin (group A), 39 patients received 75 mg pregabalin (group B), and 38 patients received placebo (group C). All patients were encouraged to engage in sexual relations twice per week for 2 weeks and to take the medication 1-2 hours before sexual intercourse. A stopwatch was used to evaluate IELT. MAIN OUTCOME MEASURE: The main outcome measure are the improvement of IELT and the reported adverse events. RESULTS: IELT significantly improved in patients who received 150 mg pregabalin, but there was no change in the other groups. CLINICAL IMPLICATIONS: Most PE patients showed a significant improvement after receiving on-demand pregabalin (150 mg). STRENGTH & LIMITATIONS: The strength of this study is that it is the first randomized controlled trial to evaluate the efficacy of pregabalin in treatment of PE. The main limitations were the small number of patients, IELT was the only primary outcome of the study, and the pregabalin cap can be identified by the patient. CONCLUSION: Oral pregabalin seems to be a promising drug for additional evaluation as a new treatment for PE. More studies are needed to evaluate the suitable dose, duration, timing, and its safety profile. El Najjar MR, El Hariri M, Ramadan A, et al.

Vancomycin-resistant Staphylococcus aureus isolated from camel meat and slaughterhouse workers in Egypt.

Background: The emergence of vancomycin-resistant Staphylococcus aureus (VRSA) represents a challenge for the treatment of staphylococcal infections in both human and animals worldwide. Although VRSA has been detected in several animal species worldwide, data on the bacterial prevalence in dromedary camels and workers in camel slaughterhouses are scarce. Methods: We investigated meat samples from 200 dromedary camel carcasses from three different abattoirs that were being prepared to be sent to the markets. Twenty hand swabs were voluntarily collected from the workers in the same abattoirs. Isolation and identification of the bacterial specimens from the samples were performed using conventional cultural techniques and biochemical identification and were confirmed by PCR amplification of the nuc gene. Antimicrobial susceptibility against nine antimicrobial agents commonly used in human and camels was tested using the disc diffusion method, and genetic analysis was performed by evaluating the mecA gene in phenotypically oxacillin (OXA)- and cefoxitin (FOX)-resistant isolates. The resistance of S. aureus to vancomycin (VAN) was tested by broth microdilution and confirmed by PCR targeting the vanA and vanB genes. The vanA and vanB genes were sequenced. Result: S. aureus was detected in both camel meat (29/200, 14.5%) and in abattoir workers (11/20, 55%). Of the collected samples, 27% (8/29, camel) and 54% (6/11, human) were identified as VRSA.All VRSA isolates carried both the vanA and vanB genes. Additionally, all VRSA isolates were also classified as methicillin-resistant S. aureus (MRSA). The vanA amplicons of the isolates from human and camel meat were homologous and clustered with a Chinese reference isolate sequence. Conclusion: This study demonstrated that VRSA is present in camel abattoirs in Egypt. Zoonotic transmission between animals and human is probable and reflects both a public health threat and a food safety concern.

Mobile teledermatology in the developing world: implications of a feasibility study on 30 Egyptian patients with common skin diseases.

BACKGROUND: The expansion of store-and-forward teledermatology into underserved regions of the world has long been hampered by the requirement for computers with Internet connectivity. To our knowledge, this study is one of the first to demonstrate the feasibility of teledermatology using newer-generation mobile telephones with specialized software and wireless connectivity to overcome this requirement in a developing country. OBJECTIVE: We sought to demonstrate that mobile telephones may be used on the African continent to submit both patient history and clinical photographs wirelessly to remote expert dermatologists, and to assess whether these data are diagnostically reliable. METHODS: Thirty patients with common skin diseases in Cairo, Egypt, were given a diagnosis by face-to-face consultation. They were then given a diagnosis independently by local senior dermatologists using teleconsultation with a software-enabled mobile telephone containing a 5-megapixel camera. Diagnostic concordance rates between face-to-face and teleconsultation were tabulated. RESULTS: Diagnostic agreement between face-to-face consultation and the two local senior dermatologists performing independent evaluation by teleconsultation was achieved in 23 of 30 (77%) and in 22 of 30 (73%) cases, respectively, with a global mean of 75%. LIMITATIONS: Limited sample size and interobserver variability are limitations. CONCLUSION: Mobile teledermatology is a technically feasible and diagnostically reliable method of amplifying access to dermatologic expertise in poorer regions of the globe where access to computers with Internet connectivity is unreliable or insufficient.
