Self-reported body silhouettes: a diagnostic instrument for anthropometric parameters.

OBJECTIVE: Routine body size measurement of anthropometric values requires professionals, standardized techniques, and calibrated tools. Therefore, there is a need for easier screening tools such as the self-reported body silhouette (Self-bosi). The aim of this study was to analyze the performance of Self-bosi as a proxy of anthropometric values. STUDY DESIGN: Prospective analytic study of the Health Workers Cohort Study. METHODS: Adult participants of the Health Workers Cohort Study were included. Then, through the calculation sensitivity and specificity of Self-bosi to detect abnormal waist circumference (WC) (≥90 cm for male and ≥80 cm for female participants), elevated body fat percentage (BF%) (≥25% for male and ≥35% for female participants), as well as overweight and obesity (≥25 kg/m2) and obesity (≥30 kg/m2). RESULTS: A total of 2471 male and 5940 female participants were analyzed. Overall, Self-bosi discriminate high WC values (area under the curve [AUC]; male participants: 0.80, female participants: 0.82); increased BF% (AUC: male participants: 0.78, female participants: 0.83); overweight and obesity (AUC: male participants: 0.81, female participants: 0.86); and obesity (AUC: male participants: 0.83, female participants: 0.89). CONCLUSION: Self-bosi is an accurate method to assess increased WC, BF%, obesity, and overweight-obesity in Mexican adults. Given its simplicity and low-cost of the self-reported body silhouette, it might be considered a useful anthropometric screening instrument in large scale epidemiological research.

Use of small intestinal submucosa for corporal body grafting in cases of epispadias and epispadias/exstrophy complex.

BACKGROUND: Male epispadias is a rare congenital urogenital anomaly in which the meatus is ectopically located along the dorsal midline of the penile shaft. In cases associated with severe curvature, functional and cosmetic outcomes could be accomplished by lengthening the shorter dorsal surface with the use of corporal grafting. Various graft materials have been used in the past for hypospadias repair including tunica vaginalis, dermis, and small intestinal submucosa (SIS). The use of SIS grafting for corporoplasty during epispadias repair has rarely been described in the literature. OBJECTIVE: To report the experience in the management of dorsal corporal body grafting using SIS in children with severe penile curvature due to epispadias. STUDY DESIGN: The authors retrospectively reviewed the charts of all patients with epispadias or bladder exstrophy/epispadias complex and severe dorsal chordee (>40°) who underwent epispadias repair with single-layer SIS for corporal body grafting. Clinical variables, surgical technique, and outcomes were analyzed. RESULTS: A total of nine consecutive patients underwent staged epispadias repair with dorsal corporal single-layer SIS grafting (summary figure). Of these, four (44.4%) had primary penopubic epispadias, one (11.1%) had mid-shaft epispadias, and four (44.4%) had bladder exstrophy/epispadias complex. The mean age at surgery was 13.4 ± 6 months. After phalloplasty with SIS grafting, there were no reported complications related to the graft during the post-operative period or follow-up visits. DISCUSSION: Although traditional techniques for epispadias repair allow some degree of corporal lengthening, they also result in abrupt medial rotation of the corporal bodies leading to torqueing and potential unsatisfactory cosmetic results. In contrast, the authors use single-layer SIS for corporal body grafting, and this study technique results in a more gradual inward rotation thus allowing more anatomical accuracy. Furthermore, an advantage of the use of SIS over other grafting materials is that there is no need to harvest an autologous graft such as tunica vaginalis or dermis. CONCLUSION: Epispadias repair using single-layer SIS corporal body grafting is an effective, safe, and feasible method, which provides satisfactory cosmesis and correction of dorsal curvature in congenital epispadias in children. Furthermore, a more normal penis appearance, without a decrease in the corporal length or diameter, is achieved with this technique.

Bladder exstrophy closure in the newborn period with external pelvic fixation performed without osteotomy: A preliminary report.

BACKGROUND: Successful primary bladder closure is the most crucial element for urinary continence in patients with classic bladder exstrophy (CBE). In the newborn period, bladder closure can be performed in the first 48 h without pelvic osteotomy or external fixation, but requires postoperative lower extremity immobilization (i.e., spica cast, Bryant's or Buck's traction). OBJECTIVE: To present a novel surgical approach for primary bladder closure for CBE using two-pin external fixation without pelvic osteotomy, and without postoperative lower extremity immobilization. STUDY DESIGN: A retrospective chart review of patients with CBE was performed at the current institution from 2000 to 2016, including all primary bladder closures with external fixation and without osteotomy or lower extremity immobilization. Patients were discharged with the external fixator in place, which was later removed in clinic. Baseline clinical and demographic variables, and follow-up data were recorded. RESULTS: Thirteen patients were analyzed; eight (61.5%) were male. Pre-operative intersymphysial distance was 3.68 ± 1.0 cm (2.0-5.0). Mean follow-up was 56.8 ± 40.3 months (10-131). One patient had a partial bladder neck dehiscence, due to pin displacement on postoperative day 1: he had the lowest gestational age of 34 weeks (Summary table). DISCUSSION: This approach used external fixation to bring the pubic bones together intra-operatively, and to decrease the tension in closing the pelvic ring and abdominal wall without osteotomy. External fixation with osteotomy and long-term immobilization, or using a spica cast without osteotomy offered the added advantage of improved wound care, due to lack of lower limb immobilization, less patient discomfort, and facilitation of mother/caregiver and newborn bonding. CONCLUSION: The two-pin external fixator without osteotomy as an adjunct to primary bladder closure in CBE patients was technically feasible. At the current institution this approach had an equivalent success rate to previous reports in the literature for primary bladder closure, decreased the length of hospital stay, and precluded the need for lower extremity immobilization. Early data for bladder capacity were encouraging.
