Background The free radial forearm flap phalloplasty is the most utilized method for penile reconstruction. Among the techniques described in the literature, evidence for the flap design after Gottlieb and Levine is poor. Methods From January 1993 until December 2015, 402 phalloplasties were performed in our clinic. Among the 247 free radial forearm flap phalloplasties, 232 free radial forearm flap phalloplasties were performed after Gottlieb and Levine in 229 patients. Operation and patient-specific characteristics were evaluated. Results This study presents the highest number of free radial forearm flap phalloplasties after Gottlieb and Levine. The rate of total flap failure was 3%; 46% of the patients were heavy smokers. Urinary fistulae and strictures are common. The revision rate for urinary fistulae and/or strictures was 1.3 per patient. The number of postoperative complications, such as bleeding (14.2%), thrombosis of the flap requiring revision (11.2%), or delayed wound healing (16.8%) was considering the high rate of nicotine abuse (45.9%) reasonable. Conclusion The free radial forearm phalloplasty in the design by Gottlieb and Levine is well established at our institution and has proven safe and reliable since 1993. The operative results are satisfactory for both patients and surgeons even in the presence of relevant comorbidities and heavy smoking. We acknowledge the long ordeal and psychological pressure that our patients suffer from, before presenting in our outpatient clinic.

Background: In an era where textured devices are being phased out due to concerns about BIA-ALCL, the Motiva SilkSurface breast implants intend to alleviate historical prosthesis-related complications. However, its safety and feasibility remain unelucidated. Methods: An analysis of Pubmed, Web of Science, Ovid, and Embase databases was performed. A total of 114 studies were identified initially, and 13 of these met the inclusion criteria and were assessed regarding postoperative parameters such as complication rate or follow-up period. Results: In 4784 patients who underwent breast augmentation with Motiva SilkSurface breast implants, a total of 250 (5.2%) complications were observed. Short- and medium-term complication rates ranged from 2.8–14.4% and 0.32–16.67%, respectively. The most common complication was early seroma (n = 52, overall incidence = 1.08%), followed by early hematoma (n = 28, overall incidence = 0.54%). The incidence of capsule contracture was 0.54% and breast implant-associated-anaplastic large cell lymphoma was not observed. Discussion: Although the majority of the studies in the current literature suggest the distinction of the Motiva SilkSurface breast implants in terms of postoperative complications and capsular contracture, its safety and feasibility need to be further elucidated with well-designed, large-scale, multicenter, prospective case-control studies. Other: No funding was received.

Objectives: Increased levels of anxiety, depression and alcohol abuse are associated with unemployment. This study compares both DSM-IV-TR Axis-I and Axis-II mental disorders between a representative and a referred sample of unemployed youths aged 16.0 to 24.9.Methods: One hundred subjects were randomly recruited on the premises of the vocational services centre in the urban region of Essen, Germany (representative sample, RS). One hundred and sixty-five subjects constituting the ‘clinical sample’ (CS) were preselected and referred by case managers to the on-site psychiatric liaison service. Structured Clinical Interviews for DSM-IV (SCID-I and -II), measures of psychopathology and health service utilization were administered.Results: Ninety-eight percent and 43% of CS and RS subjects fulfilled DSM-IV criteria for mental disorders. Mood-, anxiety- and substance-related disorders were the most common Axis-I disorders in both samples. Personality disorders were diagnosed significantly more frequently in the CS. Despite the more severe psychopathology in subjects with mental disorders from the CS compared to the RS, no differences were found for recent mental health service utilisation.Conclusion: Because the sample of unemployed youths referred by case managers was significantly more disturbed in psychiatric terms, such a pre-selection is deemed useful in conjunction with a psychiatric liaison service on the premise of a job centre.

(1) Background: While obesity is a known independent risk factor in the development of melanoma, there is no consensus on its influence on melanoma prognosis. (2) Methods: In a monocentric retrospective study, data was collected from patients who underwent sentinel lymph node (SLN) biopsy for stage IB-IIC melanoma between 2013 and 2018. Patients were divided into groups according to their body mass index (BMI). The association between BMI and melanoma features, as well as the risk factors for metastases in SLN were examined. (3) Results: Of the 1001 patients, 336 had normal weight (BMI < 25), 402 were overweight (BMI >= 25 and = 30 and = 35). Overweightness and obesity were associated with higher tumor thicknesses at time of diagnosis. Ulceration was not influenced by the patient’s weight. Metastases in sentinel lymph node was almost twice more likely in extremely obese patients than in normal weight patients. Independent risk factors for metastases in SLN in our study were tumor thickness, ulceration, and BMI > 35. (4) Conclusions: This is the first study to show higher metastases rates in high-BMI patients with melanoma, raising important questions regarding the screening and treatment of this specific patient population.
