Fournier's gangrene in childhood: a report of 3 infant patients

Fourniers gangrene is uncommon in pediatric age group, and little is known about the disease in the newborn period and infancy. Three patients, aged 10 days, 14, and 17 months, with Fourniers gangrene, were treated in our hospital. The predisposing factors were prematurity, a diaper rash, and varicella infection, respectively. Especially, prematurity and diaper rash are rare predisposing factors in the pediatric population; therefore, high index of suspicion, prompt diagnosis, conservative surgery, and multidisciplinary approach are the mainstays of management in children with Fourniers gangrene.

A continuous debate on contralateral processus vaginalis: evaluation technique and approach to patency

We present our experience with the transinguinal diagnostic laparoscopy and discuss its efficacy in evaluating the contralateral side in unilateral inguinal hernias. The possible influence of the initial side of hernia, age and gender on recognized bilateralism were also evaluated in two study groups (diagnostic laparoscopy vs clinical diagnosis). In this retrospective study, we evaluated 36 bilateral, 158 left-sided and 303 right-sided consecutive inguinal hernia cases. A total of 211 out of 461 unilateral cases underwent hernia repair and transinguinal laparoscopic evaluation of the contralateral side. Complications and difficulties of the technique, the mean duration of laparoscopy and operative times were additionally analyzed from operation charts. In this study, bilateralism was determined by transinguinal laparoscopy in Group 1 (children with a contralateral patent processus vaginalis) and clinically in Group 2 those who had a metachronous hernia. The patients were also analyzed according to the side of the inguinal hernia, age and gender in both groups. We found an overall positive contralateral patency in 41 cases (19.4%). We failed to perform a successful diagnostic laparoscopy in six cases (2.7%). No anesthetic or surgical complications were noted. Transinguinal laparoscopy did not add any considerable time to the mean operation time. The incidence of bilateralism in Group 1 was higher in girls than boys. Clinically detected bilateralism was significantly higher in 0–6 month age group and contralateral patency detected via laparoscopy was high in all other age groups. We may conclude that transinguinal diagnostic laparoscopy is a feasible technique in children. We advocate its use as a tool with minimal complication risk even in the hands of novice.

A Comparative Study of the Effects of Hemin and Bilirubin on Bilateral Renal Ischemia Reperfusion Injury

Background/Aims: The aim of this study was to determine the effects of hemin, a heme oxygenase-1 inducer, and bilirubin on renal ischemia-reperfusion (I-R) injury. Methods: 40 Wistar-Albino rats were allocated into six groups as follows: sham (S), bilirubin (B), hemin (H), ischemia/reperfusion (IR), IR + bilirubin (IRB) and IR + hemin (IRH). Conjugated bilirubin (20 mg·kg–1 i.v.) was given to rats in groups B and IRB, and hemin (50 mg·kg–1 i.p.) was given to rats in groups H and IRH just prior to reperfusion. Renal I-R was achieved by occluding the renal arteries bilaterally for 50 min. Following 6 h of reperfusion, blood was drawn to study BUN, creatinine and bilirubin, and tissue samples were harvested to determine the renal malonyldialdehyde and heme oxygenase-1 levels, and for histopathologic grading. Results: BUN, creatinine and malonyldialdehyde levels in group IRH were similar to controls whereas the results of groups IR and IRB were significantly higher (p < 0.01). There was a grade 2 damage in all I-R groups. Conclusion: This study showed the preventive effect of hemin on renal ischemia reperfusion injury. Administration of exogenous bilirubin did not prevent the I-R injury.

Gorham-Stout Syndrome with Chylothorax in a Six-Year-Old Boy

Gorham-Stout syndrome, also called “disappearing bone disease, diffuse cystic angiomatosis of bone, disseminated lymphangiomatosis, Gorham’s vanishing bone disease, phantom bone disease or idiopathic massive osteolysis, is a rare disease of unknown etiology and pathogenesis. It is characterized by rapidly progressive localized massive osteolysis associated with proliferation of vascular structures of benign origin in which the absence of new bone formation is representative. When it is complicated by chylothorax, the prognosis is poor. The authors report a 6-year-old boy with Gorham-Stout syndrome who presented with pleural effusion showing features of chylothorax, who responsed poorly to currently available therapeutic modalities.

Effect of Melatonin on Healing of Colonic Anastomosis in a Rat Model of Peritonitis

Background: The aim of this study is to determine the effect of melatonin on intestinal anastomosis in the presence of peritonitis. Material and Methods: 32 Wistar albino rats were randomized into four groups (n = 8): A (sham), B (control), C (melatonin 5 mg/kg), and D (melatonin 10 mg/kg). In group A, only cecal dissection was carried out. In the other groups, cecal ligation and puncture (CLP) followed cecal dissection in order to induce bacterial peritonitis. 24 h after the previous operation, cecal resection and iliocolic anastomosis were performed in the rats of all groups. In group C (5 mg/kg) and group D (10 mg/kg), melatonin was injected for 5 consecutive days starting after CLP. At the 48th hour of the CLP procedure, blood was drawn via the tail vein for tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) analysis, and on the 4th day of the experiment relaparotomy was carried out for bursting pressure (BP) measurements. The intestinal tissue containing the anastomotic line was then snap-frozen in liquid nitrogen and stored at –80°C for determination of tissue levels of malondialdehyde (MDA) and glutathione (GSH). Results: The tissue MDA level, blood TNF-α and IL-6 levels of group B were significantly higher than in the other groups, whereas the BP results and GSH levels of group B were found to be significantly lower than in the other groups. The results of groups C and D are statistically different from those of group B. When we compared the results of groups C and D, we found significantly higher results in terms of BP and GSH levels in group D and also significantly lower results in terms of MDA, blood TNF-α and IL-6 levels in group D. Conclusion: The findings of this experiment suggest that melatonin has a dose-independent positive effect on wound healing of colonic anastomosis.

Multifocal tuberculosis of the chest wall without pulmonary involvement

Abstract Skeletal tuberculosis (TB) is usually seen in association with a primary pulmonary focus. However, it is being increasingly recognized that the former may be encountered without the latter, particularly in children. Sternal lesions have been frequently reported in infants, presumably secondary to Bacillus Calmette-Guerin (BCG) vaccination. Herein we report a case of rib TB and a cold abscess in a child who had previously had sternal TB; that diagnosis had been missed at the time. Timely treatment of apparently solitary skeletal lesions may reduce the number of multifocal cases of skeletal TB in children.

Incomplete Duodenal Obstruction in a Newborn

A case of newborn with incomplete duodenal obstruction caused by superior mesenteric artery syndrome has been presented with this report. A full term, 1-day-old baby girl was referred to our hospital because of recurrent bilious vomiting since birth and upper gastrointestinal barium study revealed the incomplete obstruction at the 3rd part of the duodenum with a vertical abrupt cutoff. The diagnosis of superior mesenteric artery syndrome was made with ultrasonography and duodenojejunostomy was carried out. Although it is extremely rare, superior mesenteric artery syndrome should also be considered as one of the rare cause of incomplete duodenal obstruction in newborn period.

Ovotesticular disorder of sexual development and a rare 46,XX/47,XXY karyotype

Abstract Ovotesticular disorder of sexual development (DSD) is characterized by the presence of both ovarian and testicular tissues in the same individual. The most common karyotype is 46,XX. Here, we report the case of a boy with a 46,XX/47,XXY karyotype diagnosed as ovotesticular DSD by gonadal biopsy. A 5-month-old boy presented with hypospadias, unilateral cryptorchidism, and a micropenis. Pelvic magnetic resonance imaging revealed a suspicious gonad tissue that is solid in structure in the right scrotum and a suspicious gonad that is cystic in structure in the left inguinal canal. He underwent a diagnostic laparoscopy. Cytogenetic analysis of peripheral blood revealed a 46,XX/47,XXY karyotype. Histopathologic examination of the left gonad showed ovarian tissue containing primordial follicles with ipsilateral undifferentiated tuba uterina. The right gonad showed immature testis tissue. He underwent left gonadectomy and hypospadias repair, and was raised as a male. Through this rare case, we highlight the importance of histological and cytogenetic investigation in DSD.

Fluoroscopy-guided laparoscopy in the management of intraabdominal foreign body

Appendicitis or perforation as a result of intraluminal foreign body is uncommon. The method of diagnosis and proper approach for an elective appendectomy in an otherwise silent intraluminal foreign body is under dispute. A laparoscopic exploration under intraoperative fluoroscopy guidance was performed in a mentally retarded 9-year-old boy with asymptomatic foreign bodies in the right lower abdominal quadrant. The authors recommend laparoscopic appendectomy, assisted by intraoperative fluoroscopy for patients with pointed foreign bodies in the appendix.
