The aim of this study was to evaluate the combined effect of corticotomy and Low-Level Laser Therapy(LLLT) on the rate of orthodontic tooth movement. Methods: A randomized split-mouth design for 16 female patients compared the rate of maxillary canine retraction using corticotomy combined with LLLT versus corticotomy only. The device used in the present study was an In-Ga-As semiconductor diode laser emitting at 940 nm (IR) with these parameters: 0.5 W/ cm 2 power density, 5 J/cm 2 Fluence, CW, 240 sec time irradiation, weekly for the first month and twice monthly for the next three months. Assessment of the rate of canine retraction was carried out via a series of dental models. Results: A non-significant statistical rate of canine retraction was achieved by LLLT combined to corticotomy compared with the corticotomy technique alone. Conclusion: Low-Level Laser Therapy combined to corticotomy could not achieve a higher rate of canine retraction compared to the golden standard corticotomy technique alone. No long-term adverse effects on the alveolar mucosa were detected following both techniques.

This prospective study aimed to investigate the relationship between metabolic syndrome (Met S) and premature ejaculation (PE) among men. The study included 300 consecutive male patients (53.6 y ± 8.7) who attended the urology clinic (December 2013-September 2014), mostly complaining of renal/ureteric calculi. A diagnostic approach was undertaken to include demographics, clinical features and laboratory investigations of the study subjects. Both erectile function and PE were evaluated using the International Index of Erectile Function (abridged form, IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires, respectively. Results identified 182 (60.7%) men had Met S. Prevalence of PE was significantly higher in the subjects with Met S than the controls (35.2% vs 7.6%, p < 0.001). Patients with Met S and PE had significantly higher PEDT scores (15.4 vs 6.7), smaller waist circumference (108.3 cm vs 111.5 cm) and higher fasting blood sugar (187 mg% vs 161 mg%) than those with no PE (p < 0.001, 0.047 and 0.019, respectively). The other variables including IIEF-5 score, body mass index, serum triglycerides and high-density lipoprotein (14.98 vs 16.8, 30.6 vs 31.5, 192.9 mg% vs 178.1 mg% and 37.4 mg% vs 36.2 mg%, respectively) did not reveal significant differences. Both systolic hypertension and erectile dysfunction (ED) had significant associations (p = 0.047 and <0.001, respectively) with PE in Met S. In conclusion, PE has a high prevalence in Met S. Patients with Met S should be questioned about PE. Both ED and systolic hypertension may be associated with PE. Prevention of Met S should be considered, and this may be of help to decrease the prevalence of PE.

IntroductionProstate cancer is a common health problem that in the majority of cases starts to develop at the age of 50 years, reaching its peak at 60–70 years of age. A variation in its incidence and prevalence exists between western, Asian and Arabic populations.The aim of our work was to report the pattern of prostate cancer presentation in Alexandria University that as a tertiary referral center provides care for uro–oncology cases.Material and methodsData collection for all patients diagnosed with prostate cancer at Alexandria University in Egypt through the year 2012 was done.ResultsThe mean age of the patients was 67. Mean serum total PSA, prostate volume and PSAd were 149 ng/ml, 63 grams and 3.1 ng/ml/gm respectively. 25% of patients were asymptomatic diagnosed accidentally during screening for prostate cancer. The remaining group was presenting with LUTS, including 23 patients who presented initially with back pain.ConclusionsEgyptian men with prostate cancer have a markedly high PSA density and Gleason grade at diagnosis.
