Comparative StudyAcute and chronic gastric volvulus in infants and children: who should be treated surgically?
Gastric volvulus was first described by Berti in 1966. Whereas acute gastric volvulus is very rare, chronic gastric volvulus on the other hand is being diagnosed with increasing frequency. This is attributed to the liberal use of barium meal for the evaluation of infants and children with repeated attacks of vomiting and recurrent chest infection. ⋯ Barium meal should form part of their investigations. The treatment of chronic gastric volvulus depends on their symptomatology. Those with mild to moderate symptoms should be treated conservatively, while those with persistent and severe symptoms should undergo anterior (to the abdominal wall) and fundal (to the diaphragm) gastropexy without fundoplication.

Comparative StudyThe protective effects of trimetazidine on testicular ischemia and reperfusion injury in rats.
This study was designed to investigate the protective effect of trimetazidine [TMZ; 1-(2, 3, 4-trimethhoxibenzyl)-piperazine dihydrochloride], as an antioxidant agent, on torsion-detorsion-induced biochemical and histopathological changes in experimental testicular ischemia/reperfusion injury in rats. Twenty-seven male Wistar rats weighing 180-220 g were divided into five groups: control (C, n = 4), sham-operated (S, n = 4), ischemia (I, n = 6), ischemia-reperfusion (I/R, n = 6) and ischemia-reperfusion + trimetazidine (I/R + TMZ; n = 7). Control rats were used for basal normal values. ⋯ The mean seminiferous tubular diameter (MSTD) and Johnsen's score were significantly better in I/R+TMZ group than groups I and I/R. Pretreatment with TMZ decreased germ cell apoptosis and caspase-3 expression in the ischemic testis. The present results show that TMZ has a protective activity in the testicular injury caused by I/R, and provide the first evidence of the role of TMZ for the prevention of I/R-induced testicular injury.

Splenosis is the heterotopic autotransplantation of splenic tissue usually following traumatic rupture of the spleen or surgical manipulation of splenic tissue. Although it is generally asymptomatic, it may present with abdominal pain or mass. Furthermore, there may be recurrence of the hematological disorders for which the patient underwent splenectomy. We report a rare case of splenosis in a 9-year-old girl after laparoscopic splenectomy for hereditary spherocytosis, which required laparotomy due to bowel obstruction.

We reviewed a single-center experience of pediatric lung resections for various congenital and acquired benign lung conditions. Thirty-five children underwent lung resections between 1998 and 2006, their age ranging from 8 days to 12 years (mean 3 years), with a male:female ratio of 4:1. Twelve patients were neonates. ⋯ Proper preoperative diagnosis can avoid inadvertent intercostal tube insertion in patients with congenital cystic lung lesions. The histopathological diagnosis often differs from the radiological diagnosis. Emergency lobectomies for acute respiratory distress, even in neonates, result in a satisfactory outcome.

Case ReportsCalcified catheter "cast" masquerading as a retained catheter fragment after removal of an implanted venous access device.
Calcified catheter "cast" found on radiologic studies after central venous catheter removal is a rare complication that has been reported twice. Both cases were associated with thrombus. In this case report, we present a 15-year-old boy with acute lymphoblastic leukemia who demonstrated on CT scan a radiopacity in his left brachiocephalic vein after removal of an implanted venous access device. ⋯ Diagnostic studies, including venogram, excluded the presence of a retained catheter fragment. Additional procedures to retrieve a nonexistent catheter fragment were thus avoided. Therefore, a catheter "cast" should be considered as part of the differential diagnosis when calcification is found on an imaging study after removal of an implantable venous access device to prevent an unwarranted surgical exploration.
