ABSTRACT
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.

BACKGROUND: Ménière's disease is characterised by severe vertigo attacks and hearing loss. Intratympanic gentamicin, the standard treatment for refractory Ménière's disease, reduces vertigo, but damages vestibular function and can worsen hearing. We aimed to assess whether intratympanic administration of the corticosteroid methylprednisolone reduces vertigo compared with gentamicin. METHODS: In this double-blind comparative effectiveness trial, patients aged 18-70 years with refractory unilateral Ménière's disease were enrolled at Charing Cross Hospital (London, UK) and Leicester Royal Infirmary (Leicester, UK). Patients were randomly assigned (1:1) by a block design to two intratympanic methylprednisolone (62·5 mg/mL) or gentamicin (40 mg/mL) injections given 2 weeks apart, and were followed up for 2 years. All investigators and patients were masked to treatment allocation. The primary outcome was vertigo frequency over the final 6 months (18-24 months after injection) compared with the 6 months before the first injection. Analyses were done in the intention-to-treat population, and then per protocol. This trial is registered with ClinicalTrials.gov, number NCT00802529. FINDINGS: Between June 19, 2009, and April 15, 2013, 256 patients with Ménière's disease were screened, 60 of whom were enrolled and randomly assigned: 30 to gentamicin and 30 to methylprednisolone. In the intention-to-treat analysis (ie, all 60 patients), the mean number of vertigo attacks in the final 6 months compared with the 6 months before the first injection (primary outcome) decreased from 19·9 (SD 16·7) to 2·5 (5·8) in the gentamicin group (87% reduction) and from 16·4 (12·5) to 1·6 (3·4) in the methylprednisolone group (90% reduction; mean difference -0·9, 95% CI -3·4 to 1·6). Patients whose vertigo did not improve after injection (ie, non-responders) after being assessed by an unmasked clinician were eligible for additional injections given by a masked clinician (eight patients in the gentamicin group vs 15 in the methylprednisolone group). Two non-responders switched from methylprednisolone to gentamicin. Both drugs were well tolerated with no safety concerns. Six patients reported one adverse event each: three in the gentamicin group and three in the methylprednisolone group. The most common adverse event was minor ear infections, which was experienced by one patient in the gentamicin group and two in the methylprednisolone group. INTERPRETATION: Methylprednisolone injections are a non-ablative, effective treatment for refractory Ménière's disease. The choice between methylprednisolone and gentamicin should be made based on clinical knowledge and patient circumstances.

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.

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.

At present, Diabetes mellitus is considered as one of the main threats to the human health in the 21st century. It may lead to severe conditions such as blindness, end-stage of renal disease, limb amputation and a variety of debilitating neuropathies. Previous researches indicated that diabetes is caused by a complex interaction of patient's genetics, life-style and environmental factors. They also highlighted that providing quality and healthy built environment to citizens including diabetic patients would prevent poor and unhealthy condition. The Kingdom of Saudi Arabia (KSA) is one of top ten countries in the prevalence of diabetes. Little researches though were conducted in KSA in regards to the effect of environmental conditions of the built environment. In 2011, the present researchers have carried out a pilot survey on a number of diabetic patients to find out the possible impact of built environment settings on the patient's lifestyle. The research explored whether diabetic patients use smart tools in their daily life to overcome the daily life's difficulties and perform their life as normal as possible. The results showed a close link between a poor home and environmental settings, the patient's lifestyle, and the patient's health status. It also highlighted the absence of smart tools and systems use. The paper argues that certain changes to the built environment must be done and to provide a healthy and safe environment for diabetic patients. This would help these patients to abandon their bad habits and adopt healthier lifestyle.

Propolis means a gum that is gathered by bees from various plants. It is strongly adhesive resinous substance, collected, transformed, and used by bees to seal holes in their honeycombs. Bees use it to seal holes in their honeycombs, smooth out internal walls, as well as to cover carcasses of intruders who died inside the hive in order to avoid their decomposition. Propolis also protects the colony from diseases because of its antiseptic efficacy and antimicrobial properties. It also has been reported to possess various biological activities, namely anticancer, antioxidant, anti-inflammatory, antibacterial, antifungal, and hypolipidemic. The aim of this review is to evaluate the hypoglycemic effect of propolis since a little number of researches studied this effect when we compare with the huge number of papers that reported many other biological activities.
ABSTRACT
Primary ciliary dyskinesia (PCD) is usually inherited as an autosomal recessive disorder and presents with upper and lower respiratory tract infection, and mirror image arrangement in around 50% of cases. Cilia dysfunction is also implicated in a wider spectrum of disease, including polycystic liver and kidney disease, central nervous system problems including retinopathy and hydrocephalus, and biliary atresia. Cilia are complex structures, containing more than 250 proteins; recent studies have begun to locate PCD genes scattered throughout the genome. Screening tests for PCD include nasal nitric oxide and in vivo tests of ciliary motility such as the saccharin test. Specific diagnosis requires examination of cilia by light and electron microscopy, with epithelial culture in doubtful cases. This is only available in supra-regional centres, recently centrally funded by the National Commissioning Group. Treatment is not evidence based and recommendations are largely extrapolated from cystic fibrosis and other suppurative lung diseases.
