A 12-year-old male patient with a recalcitrant rectal anastomotic stricture following two failed endorectal pull-through (Soave) procedures for Hirschsprung's disease was satisfactorily managed with transanal resection using a circular stapling device. This is the first reported case of a benign colonic anastomotic stricture treated transanally with a circular stapling device in a pediatric patient.

Even in countries where it is considered endemic, splenic hydatid cyst is a very rare disease in childhood. Partial or total splenectomy has generally been the treatment of choice for this condition. This is the first report of laparoscopic cystectomy as treatment of isolated splenic hydatid cyst in childhood. A 10-year-old girl with isolated splenic hydatid cyst was successfully treated by laparoscopic cystectomy and splenic preservation. The authors have demonstrated that laparoscopic cystectomy for an isolated splenic hydatid cyst is technically feasible, safe, and is associated with a shorter hospital stay and good cosmetic appearance. © 2011 Elsevier Inc.

Objective: To study the effects of oral glucosamine sulfate on the development of osteoarthritis (OA) and to examine concomitant changes in the nociceptive behavior of rats. Methods: OA was induced in Wistar rats by anterior cruciate ligament transection (ACLT) of the right knee; the left knee was untreated. The OA. +. glucosamine group received oral glucosamine sulfate (250. mg/kg/day) in a 2-g wafer once a day for 10 consecutive weeks starting at week 5 after ACLT. The OA group was treated as above with 2-g wafers (placebo). The control group of naïve rats received 2-g wafers only. The glucosamine alone group comprised naïve rats receiving glucosamine sulfate only. Nociceptive behavior (mechanical allodynia and weight-bearing distribution of hind paws) during OA development was analyzed pre- and 3, 6, 9, 12, 15, and 18 weeks post-ACLT. Macroscopic and histologic studies were then performed on the cartilage and synovia. Immunohistochemical analysis was performed to examine the effect of glucosamine on expression of mitogen-activated protein kinases (MAPKs) in the articular cartilage chondrocytes. Results: OA rats receiving glucosamine showed a significantly lower degree of cartilage degeneration than the rats receiving placebo. Glucosamine treatment also suppressed synovitis. Mechanical allodynia and weight-bearing distribution studies showed significant improvement in the OA. +. glucosamine group as compared to the OA group. Moreover, glucosamine attenuated p38 and c-Jun N-terminal kinase (JNK) but increased extracellular signal-regulated kinase 1/2 (ERK) expression in OA-affected cartilage. Conclusion: Our results indicate that treatment with oral glucosamine sulfate in a rat OA model (1) attenuates the development of OA, (2) concomitantly reduces nociception, and (3) modulates chondrocyte metabolism, possibly through inhibition of cell p38 and JNK and increase of ERK expression. © 2010 Osteoarthritis Research Society International.

Congenital airway obstruction poses a life-threatening challenge to the newborn. We present the first case of three-dimensional (3D) modeling and 3D printing of complex fetal maxillofacial anatomy after prenatal ultrasound indicated potential upper airway obstruction from a midline mass of the maxilla. Using fetal MRI and patient-specific computer-aided modeling, the craniofacial anatomy of the fetus was manufactured using a 3D printer. This model demonstrated the mass to be isolated to the upper lip and maxilla, suggesting the oral airway to be patent. The decision was made to deliver the infant without a planned ex utero intrapartum treatment procedure. The neonate was born with a protuberant cleft lip and palate deformity, without airway obstruction, as predicted by the patient-specific model. The delivery was uneventful, and the child was discharged without need for airway intervention. This case demonstrates that 3D modeling may improve prenatal evaluation of complex patient-specific fetal anatomy and facilitate the multidisciplinary approach to perinatal management of complex airway anomalies. © 2015 by the American Academy of Pediatrics.

Although laparoscopic appendectomy (LA) is accepted treatment for perforated appendicitis (PA) in children, concerns remain whether it has equivalent outcomes with open appendectomy (OA) and increased cost. A retrospective review was conducted of patients younger than age 17 years treated for PA over a 12.5-year period at a tertiary medical center. Patient characteristics, preoperative indices, and postoperative outcomes were analyzed for patients undergoing LA and OA. Of 289 patients meeting inclusion criteria, 86 had LA (29.8%) and 203 OA (70.2%), the two groups having equivalent patient demographics and preoperative indices. Inpatient costs were not significantly different between LA and OA. LA had a lower rate of wound infection (1.2 vs 8.9%, = 5 0.017), total parenteral nutrition use (23.3 vs 50.7%, P < 0.0001), and length of stay (5.56 6 2.38 days vs 7.25 ± 3.77 days, P = 0.0001). There was no significant difference in the rate of postoperative organ space abscess, surgical re-exploration, or rehospitalization. In children with PA, LA had fewer surgical site infections and shorter lengths of hospital stay compared with OA without an increase in inpatient costs.
