[Evaluation of oral microflora status in hemodialysis and kidney transplant patients]

The number of patients with chronic renal failure is increasing every year. There are some controversies about the risk of cariogenic and periodontal diseases in these patients. This study was conducted to delineate the relationship between hemodialysis and transplant with oral microbial flora. Three groups included in our study: 1/Hemodialysis patients with being at least 6 months under dialysis procedure, 2/ Transplant patients, being transplanted for more than 2 years and 3/controls with normal BUN and Creatinine. Bacteriological study: staining and culture used for diagnosing aerobic and anaerobic bacteria SPSS 15, Chi-square, variance and t tests were used to compare the mean of microflora between groups. Candida was significantly higher in dialysis group [1.29] and transplant group [1.26] comparing controls [0.52] [P=0.05]. There was no significant difference in count of other micro organisms [streptococci, Lactobacilli, Porphyromunas] between groups. Candida was higher in hemodialysis and transplant groups comparing with control group

Management of Peyronie's Disease by Dermal Grafting

To evaluate the results of plaque excision and dermal grafting in Peyronie's disease. Twenty seven patients were scheduled to undergo plaque excision and dermal grafting for Peyronie's disease. Potency, bending of erected penis, and having painful erection were evaluated in patients before and after operation. To evaluate erectile dysfunction, we used International Index of Erectile Function [IIEF] by interviewing the patients and filling questionnaires by their partners. Doppler ultrasonography was used to determine the vascular competence of penis before and after operation in 15 patients. The disease was more prevalent between the ages of 40 and 60 years. Plaques were located as follows: dorsal in 18, right lateral in 6 and left lateral in 3. Mean plaque size was 11 [range 5 to 18] mm. After plaque excision and dermal grafting, penile deformity, erectile dysfunction, and painful erection had remained yet in 4 [15%] out of 27, 3 [16%] out of 19, and 3 [14%] out of 22, respectively. Doppler ultrasonographic study in 15 patients revealed improvement in peak systolic velocity [p<0.01]. In addition, a decrease in end diastolic velocity was noted also that was not significant statistically [p=0.26]. Resistive index did not improve after operation. This procedure showed significant improvement in penile deformity [85% of cases], erectile dysfunction [84% of cases] and painful erection [86% of cases]. We recommend plaque excision and dermal grafting as an effective procedure in treating Peyronie's disease
