Comparative StudyHepatic microcirculation in murine sepsis: role of lymphocytes.
Sepsis is a leading cause of death in pediatric intensive care units. There is growing evidence that lymphocytes play a pivotal role in mediating the microvascular dysfunction during sepsis. The objective of this study was to define the role of different subsets of lymphocytes in mediating the hepatic microvascular alterations elicited by cecal ligation and puncture (CLP), an experimental model of sepsis. ⋯ In SCID mice, the adhesion of blood cells in terminal hepatic venules was significantly decreased compared to WT-CLP mice, whereas the values in CD3+ cell-reconstituted SCID-mice, B-cell-deficient and CD4+- and CD8+-T-cell deficient mice did not differ from WT-CLP mice. ALT levels were significantly elevated only in the SCID group, when compared to WT-sham and WT-CLP mice. These findings indicate that lymphocytes mediate the microvascular dysfunction, but protect against the hepatocellular injury associated with murine sepsis.

Case ReportsMagnetic attraction leading to a small bowel obstruction in a child.
Foreign body ingestion in small children is common yet only 1% of cases require operative management of associated complications (Arana et al. in Eur J Pediatr 160:468-472, 2001). A 6-year-old boy was referred to our institution with a 12 h history of abdominal pain. This pain was diffuse and crampy in nature and associated with multiple episodes of non-bilious, non-bloody emesis. ⋯ The patient had an uneventful post-operative course and was discharged to home on the second post-operative day. This case demonstrates the complications that may occur with multiple magnet ingestion. It highlights the need for close observation and early surgical intervention in children with a suspected history of foreign body ingestion, a clinical picture of gastrointestinal distress, and radiographic evidence of a radio-opaque foreign object.

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.

Case ReportsA sewing needle migrating into the liver in a child: case report and review of the literature.
Swallowing foreign bodies is a common problem in children. Although most objects pass through the gastrointestinal tract with no untoward effect; long, sharp-pointed, or slender objects can perforate the gut. ⋯ A survey of the literature over the period from 1971 to 2006 revealed a total of five cases of childhood hepatic sewing needle together with our case. The practical lesson illustrated by this report is that the surgeon must carefully evaluate the liver when foreign body was not found in gastrointestinal system and also perforation site was found anywhere.
