We evaluated psychosocial outcomes, psychosexual development and sexual function in adolescents who had undergone surgery for proximal hypospadias. We hypothesized that these outcomes would be impaired compared to peers. We identified 55 males age 14 years or older who underwent surgery for penoscrotal to perineal (intraoperatively defined) hypospadias between 1996 and 2005. A total of 33 patients with a median age of 17.5 years (range 14 to 25) answered a Web based questionnaire with self-constructed questions, completed the validated Psychological General Well-Being Index, Body-Esteem Scale for Adolescents and Adults and Penile Perception Score, and underwent clinical evaluation. A total of 31 patients with distal hypospadias (median age 19 years, range 14 to 35) and 25 age matched healthy men (17.5 years, range 14 to 25) served as controls. Interest in sex, age at sexarche and satisfaction with sexual experiences were comparable between patients and controls. Three patients with proximal hypospadias (10%) and 1 control (4%) reported occasional erectile problems. Three patients with proximal hypospadias (11%), 1 patient with distal hypospadias (3%) and 1 control (4%) affirmed anejaculation. There were no differences in results between validated questionnaires. Patients with proximal hypospadias were more dissatisfied with penile length (39%) compared to controls (12%, p = 0.049). Concerning physical contact, 10 patients (38%) expressed uncertainty. Extra support in school was more frequent among patients with proximal hypospadias (p = 0.024 vs distal hypospadias, p = 0.068 vs control group). Despite concerns regarding penile length, sexual experiences were comparable to those of other adolescents, although more than a third of patients with proximal hypospadias demonstrated uncertainty on questions relating to desire for physical contact. Specialized tutoring in school was more common in patients with proximal hypospadias. Continuous followup throughout childhood allowing extra time for age adequate information and support is warranted.

Proximal hypospadias repair is associated with a considerable complication risk. Long-term follow-up is required to present realistic expectations in pre-operative counseling. To investigate adolescents after childhood surgery for proximal hypospadias in a prospective cohort study describing the urological outcome, complication rates and patient satisfaction with penile appearance. 39 adolescents ≥14 years with penoscrotal to perineal hypospadias and primary urethroplasty (tubularized incised plate (TIP), preputial flap as Onlay or tubularized (Duckett)) from 1996 to 2005 at a single center were evaluated. The clinical assessment, at Md 16.5 years (14-25), included voiding history, genital examination including the Hypospadias Objective Scoring Evaluation (HOSE), uroflowmetry plus chart data from previous urinary flows and evaluation of patient satisfaction using the Penile Perception Score (PPS). Twenty-nine patients with penoscrotal and 10 with scrotal/perineal hypospadias underwent surgery with TIP (N = 14), Onlay (N = 14) and Duckett (N = 11). Uroflows improved significantly compared with prepubertal maximal flows. Impaired flow rate (3 years, illustrating the need for long-term follow-up. Patient satisfaction with a deviant meatal position is rarely reported [1,2]. Our results support a conservative approach to an asymptomatic retracted meatus. Limitations of this descriptive study are the non-comparable groups and the retrospective data for correlation, impeding evaluation of prognostic outcome-factors. The shorter penile length found in patients after plication, and increased curvature after TIP, is therefore merely descriptive. However, the findings are in line with earlier publications suggesting limited use of TIP, and plication (recommending ventral lengthening instead) to avoid penile shortening and curvature in these cases [3-5]. The urological long-term outcome after proximal hypospadias repair is good, although late reoperations are common. In adolescence, patients were dissatisfied with the short penile length but satisfied with meatal position, indicating that in proximal hypospadias, preserving penile length and correcting curvature are prioritized over a distal meatus.

Two complementary techniques for the characterisation of the fine scale microstructure of materials are briefly described: three-dimensional atom probe (3-DAP) analysis and energy filtered transmission electron microscopy (EFTEM). The 3-DAP is especially suited for the characterisation of clustering and of the chemistry and size of very small precipitates, in particular when several phases are present. Energy filtered transmission electron microscopy is useful for determining size, volume fraction and number density of precipitates in the approximate size range 20–200 nm, also when several phases are present. As examples of the usefulness of a combination of these techniques, results from two types of complex martensitic steels are reviewed: the sequence of precipitation in a high strength maraging steel, Nanoflex, and the microstructure of creep resistant 9–12%Cr steels.

Spina bifida includes a spectrum of different neural tube defects. Myelomeningocele is the most serious type and is associated with a risk of paralysis and sensory dysfunction below the affected level, bladder/bowel dysfunction, brain dysmorphology, and impaired health-related quality of life (HRQoL). The aim of this study was to describe the establishment of linguistic, content and face validity of the Swedish version of a Quality-of-Life Assessment for children (QUALAS-C, n = 10 items), teenagers (QUALAS-T, n = 10 items) and adults with spina bifida (QUALAS-A, n = 15 items) based on the original US English versions. The process included close collaboration with the original instrument developer and complied with international standards on patient-reported outcome measurements. The procedure includes forward translation, expert and patient/parent review and reconciliation, back translation, back translation review and cognitive debriefing interviews with 16 people with spina bifida aged 8 to 33, providing them with the possibility of evaluating the clarity, adequacy, and comprehensiveness of QUALAS-C, QUALAS-T and QUALAS-A, respectively. The interviews lasted a median of 15 min (range 8–16) for QUALAS-C, 10 min (range 9–15) for QUALAS-T and 24 min (range 9–38) for QUALAS-A. Four main issues/topics needed attention and discussion after both the forward and back translation. Following the back translation review, all issues were resolved. The patient feedback revealed recognition of the HRQoL issues included in QUALAS, and also difficulties in understanding some questions. After the patients’ evaluation, four items were reworded for clarity. No study participant reported a wish to add to or remove questions from QUALAS. Hence, the Swedish versions of QUALAS became conceptually equivalent to the original US English versions and achieved linguistic, content and face validity. While empowering the voices of people with spina bifida, these results also enable their HRQoL to be properly assessed in research and clinical care in Sweden and in international studies.
