Evaluation of daily avanafil efficacy in improving the endothelial function in Egyptian males with erectile dysfunction

Avanafil is a highly selective and potent oral phosphodiesterase type 5 inhibitor. However, its impact on the soluble markers of endothelial function has not been investigated yet. This study was conducted to assess the effect of daily avanafil on the endothelial markers' serum level and erectile function in patients with erectile dysfunction. In this work, we randomly divided 140 males with erectile dysfunction and other diseases commonly associated with endothelial dysfunction like diabetes mellitus, hypertension and dyslipidaemia into two equal groups: treatment group, treated with 50mg daily oral avanafil, and control group, treated with placebo. The International Index of Erectile Function-5 score and the serum levels of nitric oxide, cyclic guanosine monophosphate and endothelin-1 as markers of endothelial function were measured at baseline and after four weeks of treatment in both groups. At the end of treatment period, those randomised to avanafil achieved statistically significant improvement in erectile function, nitric oxide, cyclic guanosine monophosphate and endothelin-1 levels from baseline versus placebo regardless the type and duration of associated comorbidity as well as the duration and severity of erectile dysfunction. These results permitted us to suggest that daily avanafil can improve the impaired endothelial function associated with the erectile dysfunction.     

Multiple myeloma: a descriptive study of 217 Egyptian patients

Multiple myeloma is a neoplasm of plasma cells that results in the overproduction of light and heavy chain monoclonal immunoglobulins. The incidence rate increases with age, particularly after 40 years, and is higher in men. To determine the clinical and laboratory characteristics and survival of diagnosed Egyptian multiple myeloma patients admitted to the Haemato-Oncology Department between 2000 and 2010. Records of all patients in whom multiple myeloma was diagnosed at the Kasr Al Aini Hospital between 2000 and 2010 were included in this retrospective study. The mean age of patients was 58.5 years (range, 27–80 years). Fifty-nine percent were males. The majority of patients (73 %) had an immunoglobulin G monoclonal band and 70 % were Kappa chain-positive. Mean overall survival was 37.5 months (range, 1–84 months). Survival analysis was statistically insignificant with respect to age, sex, International Staging System and type of treatment (p?>?0.05). Our records were largely comparable to those reported in Chinese studies but different from those noted in Western and Arabic countries.     

Role of Helicobacter pylori in common rosacea subtypes: A genotypic comparative study of Egyptian patients

Helicobacter pylori was incriminated as an etiological factor of rosacea. However, there is still controversy about this association. We conducted a comparative study in order to assess the role of H. pylori in rosacea patients who had dyspeptic symptoms. The study included 68 patients and 54 controls. Screening for H. pylori was performed and positive cases were referred for gastric endoscopy. The inflammatory response and bacterial density were evaluated in gastric biopsy. H. pylori vacA alleles, cagA and iceA genotypes were assessed by polymerase chain reaction. We found that 49 rosacea (72%) and 25 controls (46.3%) were infected with H. pylori. Thirty‐one rosacea cases were papulopustular (PPR) while 18 were erythematotelangiectatic (ETR). Gastric ulceration was higher in PPR cases (38.7%) than ETR (11.1%) and controls (12%). A significant inflammatory reaction was observed more in PPR cases (74.2%) compared with 44.4% in ETR (P = 0.04) and 44% in controls (P = 0.02). Analysis of H. pylori genotypes revealed that vacA s1m1 was more identified in PPR cases (54.8%) compared with 22.2% in ETR (P = 0.03) and 16% in controls (P = 0.003). There was a significant elevation of cagA/vacA s1m1 positivity in PPR cases. After the eradication regimen of H. pylori, a significant improvement (P < 0.05) was observed in 15 out of 27 PPR cases (55.6%) compared with three out of 17 ETR (17.6%). We concluded that H. pylori has a significant role in rosacea patients who had dyspeptic symptoms. The PPR type is more influenced by H. pylori and this is regarded as being because of certain virulent strains that increase the inflammatory response in gastric mucosa and also in cutaneous lesions.     

Validity and reliability of wheelchair sitting posture measures using Coach’s Eye in abled subjects

People in wheelchairs spend a long time in the sitting position and often incur alignment problems resulting in neck and back pain. This study: (1) assessed the validity/reliability of Coach’s Eye (CE) smart device application, (2) examined the effect of seat to back support angle adjustments on head, neck, and shoulder posture in the sitting position, and (3) compared changes in cervical rotation at each back support angle. Abled subjects sat in a wheelchair with back support angles positioned at 90°, 100°, and 110°. CE, as well as ImageJ software, was used to analyze three angles: sagittal head angle (SHA), cervical angle (CVA), and shoulder angle (SA). There were highly significant differences for CVA and SA (p < 0.001) among the three seat to back support angles. Validity of CE was examined by correlating CE with ImageJ scores. CE had high validity for all angles (r = 0.99, 0.98, 0.99 respectively, p < 0.001). Inter-rater reliability for SHA, CVA, and SA was high (intraclass correlation coefficient [ICC] ranged from 0.95 to 0.99). Head (CVA) and shoulder (SA) alignment was closest to neutral posture with back support angles set at 110° and 90°, respectively.
