Recurrent tethered cord: outcome and follow-up of 20 de-thetering for symptomatic spina bifida: choort study.

Objective: The objective of this study was to evaluate the prevalence of tethered cord among patients in the postoperative period of open and occult spina bifida. To identify warning signs for its early diagnosis, as well as outcomes after the new surgical approach.

Methods: Retrospective study of patients followed at the Pediatric Neurosurgery Department of the Federal University of São Paulo with spinal dysraphism.

Transition of care in pediatric surgery.

Objective: To identify among pediatric surgeons across Brazil how the transition of pediatric patients to adult clinics is carried out.

Methods: A questionnaire was emailed to pediatric surgeons registered with the Associação Brasileira de Cirurgia Pediátrica in 2018. The data assessed included training time, maximum age of care, subspecialty of practice, outpatient follow-up of adult patients, reason for continuing care of adult patients, referral to adult specialties, concern with transition of care, and what has been done to improve it.

Vaginoplasty with Oxidized Cellulose in Mayer-Rokitansky-Küster-Hauser Syndrome.

Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is the major cause of vaginal agenesis. Vaginoplasty with oxidized cellulose has been used by gynecologists as a surgical option in vaginal agenesis; however, it is not very widespread among pediatric surgeons. A case of MRKHS who underwent vaginoplasty with oxidized cellulose is reported here.

The use of mesenchymal stem cells in bladder augmentation.

Purpose: To compare integration of bladder acellular matrix (BAM) with the bladder when seeded with mesenchymal stem cells (MSC) and when MSC are injected intravenously (IV).

Methods: MSCs were isolated from bone marrow of EPM-1 Wistar male rats. Female rats were distributed into: Group A-BAM augmentation; Group B-BAM augmentation and MSCs IV administered; Group C-BAM-MSC seeded augmentation.

Anterior sagittal approach without splitting the rectal wall.

Introduction: The anterior sagittal transrectal approach (ASTRA) has already become popular to treat lesions in the proximal urethra such as trauma, duplicity and stenosis, prostatic utricle, urethral-vaginal fistulas and urogenital sinus anomalies. It provides much better exposure than the traditional perineal approach. Morbidity caused by this technique could be potentially decreased if the anterior sagittal access were to be made without sectioning the rectum.

Renal tumor and trauma: a pitfall for conservative (correction of conversative) management.

Purpose: Conservative management has been largely used for renal trauma. Although this approach is safe and highly recommended, it can hide a pre-existing unknown condition, such as tumors or urinary malformations. A high index of suspicion is needed for early recognition of these conditions.

Unusual case of epigastric heteropagus twinning.

Asymmetrical conjoined twins or heteropagus twins are extremely rare. They are characterized by an incomplete component (parasite) that is normally smaller and dependent on the host (autosite). In cases of an epigastric heteropagus twin, the insertion occurs in the epigastrium.
