Long term cardiopulmonary effects of closed repair of pectus excavatum.
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 function. This study examined the effects at 3 months post-bar removal of closed repair of pectus on pulmonary function, exercise tolerance and cardiac function. ⋯ Objective measures of FEV1, total lung capacity, diffusing lung capacity, O(2) pulse, VO(2max), and respiratory quotient all showed significant improvement compared to preoperative values, while normalized values of cardiac index at rest did not (All values normalized for height and age, comparisons P < 0.05 by student's paired t test). These results demonstrate a sustained improvement in cardiopulmonary function after bar removal following closed repair of pectus excavatum. These findings contrast with results from previous studies following the open procedure, or with the closed procedure at earlier time points; the long term physiological effects of closed repair of pectus excavatum include improved aerobic capacity, likely through a combination of pulmonary and cardiac effects.

Laparoscopic appendectomy is a favorable alternative for complicated appendicitis in children.
Laparoscopic appendectomy in children is a generally accepted procedure for the treatment of non-complicated acute appendicitis. Nevertheless, the role of laparoscopy in complicated appendicitis is more controversial. The objective of this study was to examine the safety, efficacy and complications of laparoscopy in children with complicated appendicitis. ⋯ It does not increase the incidence of complications even with complicated appendicitis. Contrary to the previous studies, we did not have increased incidence of intra-abdominal collection in this review. However, prospective randomized controlled trials are needed to verify these findings.

Randomized Controlled TrialCould adding magnesium as adjuvant to ropivacaine in caudal anaesthesia improve postoperative pain control?
Recently, most studies reported magnesium as a N-methyl-D-aspartate receptor antagonist and its analgesic and perioperative anaesthetic effects have been discussed with central desensitization pathway. We investigated the effects of caudal ropivacaine plus magnesium and compared with ropivacaine alone on postoperative analgesia requirements. After hospital ethic committee's consent, 60 patients (ASA I-II, 2-10 years old) who had lower abdominal or penoscrotal surgery were enrolled in the study. ⋯ According to demographic characteristics, there were no significant differences between the two groups (P>0.05). POPS, CHEOPS, Bromage Motor Scales, analgesia duration and adverse effects were similar in Group R and Group RM. It has been shown that addition of magnesium as an adjuvant agent to local anaesthetics for caudal analgesia has no effect on postoperative pain and analgesic need.

Ingested gastrointestinal foreign bodies: predisposing factors for complications in children having surgical or endoscopic removal.
A retrospective study was performed to determine the predisposing factors associated with the complications of ingested gastrointestinal (GI) tract foreign bodies (FBs) in children who had surgical or endoscopic removal. The study was performed in 161 children who had endoscopic or surgical removal. The clinical data were evaluated in two groups. ⋯ Type, radiopacity, location and duration of the ingested GI tract FB determine the outcome. A delayed diagnosis is the most significant factor increasing the risk of complications. Physician must maintain a high index of suspicion and a more extensive history; physical examination and radiodiagnostic investigation should be obtained in suspected cases.
