Human amniotic membrane vs collagen in the treatment of superficial second-degree burns in children.

OBJECTIVE: The authors compared a 1-time application of bovine collagen and human amniotic membrane (HAM) to treat children with superficial second-degree burns. MATERIALS AND METHODS: A prospective, blinded, internally randomized trial of 43 children was conducted. Fresh HAM (prepared in-house at the Christian Medical College, Vellore) and bovine collagen were applied to different halves of each wound and dried naturally to form a hard, shell-like, so-called exoskeleton. The shell was shed as epithelialization occurred beneath it. Clinical examination and serial photographs were used to track progress until the wound healed completely, as well as at 3 and 6 months after the burn injury. Two burns surgeons blinded to the material used evaluated the resulting scars using the Vancouver Scar Scale. RESULTS: The 43 children presented 3 hours after burn injury on average. A 1-time application was successful in 40 children (93%). After the dressing dried, all parents reported that their child was pain free and the exoskeleton could be handled over the burned area. A total of 16 children (37%) with a low-grade fever at the time of application were treated with simple antipyretic agents. Eight children reported itching at the dressing site. The dressing did not take or was removed in 3 children (7%). Minor serous collections occurred in 8 children who subsequently underwent aspiration. The median time to healing was 10 days in both study arms, with no significant difference in scarring between the 2 materials. Children with earlier shedding of the shell had significantly better scar quality (P <.001). CONCLUSIONS: Collagen and HAM are safe and provide a one-time ambulatory option for burn dressing with comparable time to healing and scarring. Earlier shedding of the dressing is predictive of better scar quality. Because HAM is inexpensive and simple to prepare and store, it is an excellent choice for use in economically disadvantaged areas where collagen may be unavailable.

Stricture Urethra in Children: An Indian Perspective.

BACKGROUND: Pediatric urethral stricture and its treatment have functional implications in the growing child. SUBJECTS AND METHODS: A retrospective study of records on urethral strictures encountered in our institution between January 2005 and May 2016 yielded 23 boys against a backdrop of 19,250 admissions during the same period; stenosis and strictures after hypospadias repair were not included in this study. Demographic data were collected from the charts, and the success of repair was assessed clinically by success of repair was assessed clinically by observing for presence or absence of symptoms such as dribbling, straining at voiding, adequacy of urinary stream and radiologicaly by assessing the micturition phase of voiding cystourethrogram. Success was defined as successful initiation, flow, and completion of voiding with radiological evidence of reestablishment of urethral continuity. RESULTS: The most common cause of urethral stricture was perineal or pelvic trauma (56.5%). Three after surgery for anorectal malformation (13.04%) and 2 (8.6%) followed otherwise unspecified urethritis. Transperineal and transpubic anastomotic routes were used for surgery. Redo surgery was required in 47.8%. The overall success rate was 82%. A self-catheterizable mitrofanoff channel was created as part of the primary procedure in 63.6% (7/11) or after the failure of the first procedure in 36.3% (4/11). CONCLUSION: The majority of urethral strictures are long-segment strictures or those with complete disruption not amenable to endoscopic techniques. The aim of the surgery is to obtain end-to-end opposition of healthy proximal and distal urethra. The route - transperineal or transpubic - which will give the best access to the ends of the urethra is determined by the location and extent of the stricture and the alteration in anatomy as a consequence of the pelvic fracture. Even after the introduction of laser and endoscopic techniques, surgical repair is required to tackle the majority of urethral strictures in children.

Recurrent and metastatic congenital mesoblastic nephroma: where does the evidence stand?

PURPOSE: Fifty years ago, Bolande described Congenital Mesoblastic Nephroma (CMN) as a benign lesion. Unexpected aggressive clinical behaviors prompted a sub-classification based on histology. Recent molecular genetic evidence has identified the aggressive cellular variant to be the renal manifestation of congenital infantile fibrosarcoma. We submit a reappraisal and analysis of the available literature on recurrent and metastatic CMN. METHODS: An electronic search of PubMed, MEDLINE, EMBASE, and Scopus yielded 38 children with local recurrence and/or metastases. RESULTS: Of the 38 children with local recurrence and/or metastasis, 59% were girls. Median time to recurrence was 6 months (range 1-12 months). The commonest sites of metastases were the lung (39%) and liver (29%). Fifty percent of these children died of disease. The outcome of additional chemotherapy (p = 0.5) did not differ from that of surgery alone. The choice of chemotherapy did not influence the outcome (p = 0.6). CONCLUSIONS: Recurrence and metastasis in cellular CMN are much more common than described earlier and carry a high mortality. Children with cellular and mixed CMN require close clinical and radiological follow-up for a minimum of 12 months after primary surgery. Surgery is the mainstay of the treatment of recurrent and metastatic lesions. Neoadjuvant chemotherapy is recommended only if the lesion is inoperable. Targeted therapy may be an option in treatment of refractory cases.

Surgical approach to the palpable undescended testis.

An undescended testis may be associated with abnormal testicular development and function. A number of testes that are undescended at birth have been observed to descend spontaneously. The goal of orchidopexy remains to place those testes in the scrotum that would not have descended spontaneously. How long should the surgeon wait for spontaneous descent? By what age should the testis be positioned in the scrotum to avert further damage? Does earlier intervention result in a better functioning testis? Do different surgical techniques differ in their success in retaining the testis in the scrotum when dealing with the palpable undescended testis? This article reviews the current information on the timing and types of surgical intervention of the palpable undescended testes and their outcomes.

An air insufflation device for reduction of intussusception in children.

The authors have developed a portable device for insufflation of air reliably at pressures accepted as safe for effective reduction of intussusception in children under fluoroscopic guidance. The results of reduction with the device were equal to those by saline enema reduction under ultrasound guidance.
