The closed or “Nuss” repair of pectus excavatum is widely accepted for correction of moderate to severe deformities. Patients typically report significant subjective improvements in pulmonary symptoms, and short and medium term evaluations (up to 2 years with the bar in place) suggest modest improvement to cardiac function but a decrease in pulmonary(More)
BACKGROUND Bowel preparation prior to colonic surgery usually includes antibiotic therapy together with mechanical bowel preparation (MBP). Mechanical bowel preparation may cause discomfort to the patient, prolonged hospitalization, and water and electrolyte imbalance. It was assumed that with the improvement in surgical technique together with the use of(More)
BACKGROUND Aggressive chemotherapy/radiotherapy for cancer may cause gonadal failure in young female survivors. The putative aim of ovarian tissue cryopreservation is to restore fertility by transplantation of a patient's frozen-thawed ovarian tissue or, further into the future, by in vitro maturation of frozen-thawed oocytes followed by in vitro(More)
OBJECTIVES Colorectal carcinoma, a common adult malignancy, has an estimated childhood incidence of 0.3 to 1.5/million in Western countries and 0.2/million in Israel. Diagnosis is difficult because adult screening measures are unfeasible in children. The tumor is frequently associated with predisposing genetic factors, aggressive biological behavior, and(More)
BACKGROUND The "Nuss" procedure for repair of pectus excavatum is performed with increasing frequency worldwide. We describe a technique of performing relaxing or "kerf" incisions along the cartilaginous ribs at the point of maximal chest wall concavity to facilitate retrosternal dissection and to reduce chest wall tension. The effects on operative(More)
BACKGROUND Standard modalities to assist in determining the extent of chest wall developmental deformities in patients include x-ray and computed tomography (CT). The purpose of this study is to describe an optical imaging technique that provides accurate cross-sectional images of the chest, and to compare these with standard CT-derived images of chest wall(More)
Polyuria is not considered an absolute indication for pre-transplant nephrectomy; however, it may complicate post-transplantation fluid management. Bilateral native-kidney laparoscopic nephrectomy was performed at our centre in two patients (four kidneys) 1 month after they had received a living related-donor renal transplant. The indication for nephrectomy(More)
Previous analyses of the safety of the conservative versus the operative approach to the treatment of liver and spleen blunt injuries in children often failed to account for differences in quality of care and expertise among dedicated pediatric trauma center, non-pediatric centers, centers without trauma units, and non-trauma centers. To eliminate this(More)
CONTEXT The signals initiating growth of primordial follicles are unknown. Bone morphogenetic protein 15 (BMP15) and growth differentiating factor 9 (GDF9) are promising candidates. OBJECTIVE The objective of the study was to evaluate for the first time the effects of human recombinant BMP15 and human recombinant GDF9 on the in vitro development of human(More)
PURPOSE Over the last 15 years thoracoscopic lobectomy for congenital and acquired lesions has become an accepted modality in pediatric thoracic surgery. There is still debate about the need to perform a complete lobectomy for some of these lesions, and some advocate observation rather than resection, despite possible long-term complications of untreated(More)
