Beyond the psychological trauma parents go through, they have to deal with the lower urinary tract symptoms including acute urine retention their baby boys suffer due to meatal stenosis from the scaring process that ensues. We report on the cosmetic and functional outcomes in two patients ten years after neo-glans reconstruction following total glans amputation as a complication of circumcision and discuss the lessons learned over the period.展开更多

Furthermore, there has been scant research on glans penis augmentation due to a poor understanding of glans anatomy, technical difficulty, and a lack of suitable substances for augmentation. Cross-linked dextran gel is a newly developed filler for soft-tissue augmentation. We evaluated the efficacy and safety of using a novel technique to inject cross-linked dextran gel for glans penis augmentation during a 24-week follow-up study. This prospective, single-arm, multicenter study enrolled twenty healthy adult men who underwent glans penis augmentation between June and August 2013. Cross-linked dextran gel was injected into the glans penis using a simple and easy technique. The sizes of the glans penis and individual satisfaction were assessed. Any adverse event was also reported. A total of 18 individuals were analyzed; two of them were lost to follow-up. The mean procedure time and injected volume were about 30 rain and 6.6 ＋- 0.9 ml, respectively. The mean surface areas of the glans at baseline and 24 weeks were 20.0 _＋ 3.5 cm2 and 33.6 -＋ 5.4 cm2, respectively, representing a mean increase of 68.7% _＋ 14.0% （P 〈 0.001）. Sixteen individuals （88.9%） were satisfied with the outcomes, and none were dissatisfied. There were no serious adverse events during the study. Cross-linked dextran gel injection for glans penis augmentation was easy and showed a significant augmentative effect on the glans penis, good durability, and was well tolerated without serious adverse events. Therefore, cross-linked dextran gel injection may be an effective, new technique for glans penis augmentation.展开更多

Larsen & J. Mood and Curcuma cf. xanthorrhiza Roxb.Methods: The essential oils were obtained by hydro-distillation and analyzed by gas chromatography/mass spectroscopy. Agar-well diffusion assay was used to study the antimicrobial activity and also broth-micro dilution techniques were examined for minimum inhibitory concentration(MIC) against four bacterial strains and yeast.Results: The gas chromatography/mass spectroscopy analysis showed monoterpenes predominantly(88.53%) in the rhizome oil of Curcuma cf. xanthorrhiza. Sesquiterpenes(50.10%) was the most abundant component in the essential oil of C. glans, while monoterpenes(45.55%) and sesquiterpenes(45.81%) were found in C. aeruginosa with a significant amount. The major components of C. aeruginosa were characterized as camphor(29.39%) and germacrone(21.21%). Germacrone(15.76%), b-pinene(9.97%)and camphor(9.96%) were found as major compounds in the rhizome oils of C. glans while a-terpinolene(24.86%) and p-cymen-7-ol(12.17%) were found as major compositions in Curcuma cf. xanthorrhiza. The essential oils were tested against four bacterial strains and yeast. As a result, the rhizome oil of C. aeruginosa exhibited potent activity against Staphylococcus aureus [inhibition zone(21.94 ± 0.24) mm, MIC 125 μg/mL],Bacillus cereus [inhibition zone(20.83 ± 0.36) mm, MIC 125 μg/mL], and Candida albicans [inhibition zone(11.60 ± 0.30) mm, MIC 250 μg/mL].Conclusions: The essential oils from three Curcuma species possessed greater activity against the gram-positive bacteria(Staphylococcus aureus and Bacillus cereus) than gram-negative bacteria(Escherichia coli and Pseudomonas aeruginosa). The results suggest that the essential oils from the fresh rhizome of Curcuma spp. might be a potential source of natural antimicrobial substances.展开更多

Although various methods have attempted to achieve both goals, none have succeeded entirely. In this report, we introduce a novel reconstructive technique on a 64-year-old patient with squamous cell carcinoma of the glans penis. The technique consisted of two staged procedures. First, a dermal substitute, consisting of bovine collagen, was sutured onto the defect after partial glansectomy and three weeks later, the integrated dermis was covered with autologous non-meshed partial thickness skin graft. Use of this dermal substitute in a staged fashion allowed for ability to await final pathologic margins prior to definitive reconstruction and increased dermal thickness. After 9-month follow-up, sexual function returned within 3 months and the patient remained healed. We found this technique to be useful in concurrently preserving penile function and cosmesis. Future studies should include more patients and longer follow-up.展开更多
