Intussusception Caused by Heterotopic Pancreas: A Tunisian Case Series of 5 Pediatric Patients.

Heterotopic pancreas (HP) is a rare congenital developmental anomaly of the gastro-intestinal tract, defined as the presence of pancreatic tissue found in ectopic sites. Intussusception caused by isolated HP is extremely rare. Pediatric reports concerning this pathology are case reports.

[Ureterocele associated with simplex ureter in children: clinical and therapeutic features].

Ureterocele is a pseudo-cyst dilation of the terminal submucosal ureter. It is a rare malformative uropathy, in particular associated with simplex ureter. We conducted a retrospective study over a period of 10 years.

Peritoneal Hydatid Cysts in Children: A Case Series of Rare Echinococcosis Localization.

Peritoneal hydatid cysts are rare in children even in endemic areas. The primary or secondary origin of this site remains controversial, especially in children. Secondary peritoneal hydatid cysts are mainly the result of spontaneous or traumatic rupture of concomitant liver cysts or the leakage of cystic content during surgery.

[Prenatal diagnosis of a giant cystic lymphangioma in the axillothoracic wall].

Cystic lymphangiomas are benign malformative tumors of the lymphatic vessels, rare but potentially serious and usually located in the cervical region. The diagnosis is usually easy, but the treatment is sometimes difficult because of their location and extension into the surrounding tissue. We report a case of giant cystic lymphangioma of the right axillary-thoracic wall diagnosed by prenatal ultrasound at 20 weeks gestation.

Soave transanal one-stage endorectal pull-through in the treatment of Hirschsprung's disease of the child above two-year-old: a report of 20 cases.

Background: The definitive treatment of Hirschsprung's disease is the removal of the aganglionic bowel by a pull-through surgery. In most cases, this surgery is performed in infancy or in the neonatal period as presentation in older children and adulthood is uncommon.

Materials And Methods: It is a retrospective study of 20 patients above two-year-old who underwent a transanal Soave one-stage endorectal pull-through procedure for Hirschsprung's disease between January 2002 and December 2010.

Video-assisted surgery in the management of hydatid renal cyst in children.

Renal hydatid disease is rare in children. Open surgery is the traditional method of treatment, but minimally invasive techniques are being increasingly used. Herein, we report our experience with laparoscopic management of renal hydatid cyst in four children via a transperitoneal approach in three cases and a retroperitoneoscopy in one.

[Esophageal strictures in children with epidermolysis bullosa].

Unlabelled: Esophageal stricture is a rare but often severe complication of recessive dystrophic epidermolysis bullosa in children. The purpose of the study was to review this digestive complication with emphasis on diagnostic modalities and therapeutic management.

Patients And Methods: This was a retrospective study of two pediatric cases of esophageal stenosis that occurred during generalized recessive dystrophic epidermolysis bullosa of the Hallopeau-Siemens type.

[Retrovesical hydatid cyst in children: report of 3 cases].

Retrovesical hydatid cyst is rare, even in endemic regions. From a presentation of three cases, the authors will review the clinical findings and illustrate the imaging features of this pathology and relate diagnostic and therapeutic difficulties.

[Cystic echinococcosis in children in Tunisia: fertility and case distribution of hydatid cysts].

Cystic echinococcosis, which commonly starts during childhood or adolescence, is a serious problem of public health in Tunisia. For 121 children (161 cysts), the localization and fertility of cysts as well as viability of their protoscoleces were determined. Results indicated that the lung was the primary localization of cyst (59%) followed by the liver (35%).

Genetic differences between Tunisian camel and sheep strains of the cestode Echinococcus granulosus revealed by SSCP.

Ovine and dromedary Echinococcus granulosus isolates from Tunisia were identified as G1 and G6 strains based on polymorphism of the mitochondrial cytochrome C oxydase CO1. Single strand conformation polymorphism (SSCP) was used in order to examine the genetic variation within and between Tunisian G1 and G6 strains and to estimate the extent of selfing. The dromedary isolates are genetically distinct from sheep isolates (high value of genetic variation between populations: Fst= 0.

[Omental lipoblastoma: a case report].

Lipoblastoma is a rare benign neoplasm of foetal fat tissue. To our knowledge, less than ten cases of omental lipoblastoma have been reported in the literature. We present a new case of omental lipoblastoma in a 3-month old girl.

[Imaging of pulmonary hydatid cyst in children].

Purpose: We present the various imaging features of pediatric pulmonary hydatidosis based upon a series of 232 cases. The importance of chest radiographs and thoraco-abdominal ultrasound is emphasized.

Patients And Methods: A retrospective study of 232 children with pulmonary hydatidosis is presented.

Molecular evidence of ovine (G1) and camel (G6) strains of Echinococcus granulosus in Tunisia and putative role of cattle in human contamination.

Three hundred and seventy-two cysts coming from 50 humans, 166 cattle, 153 sheep and 3 camels were collected in order to establish some epidemiological molecular information in Tunisia for the first time. The analysis by PCR-RFLP of ITS1 sequence showed that all the human, ovine and bovine cysts were due to the common sheep strain of Echinococcus granulosus. The sequencing of the CO1 gene of 37 isolates confirm the G1 genotype of this strain.

Genetic relationships between sheep, cattle and human Echinococcus infection in Tunisia.

Allozyme variation at seven polymorphic loci (GPI, EST, MDH, MPI, DIA, PEP, PGM) was studied to examine genetic variation within and between sheep, cattle and human populations of Echinococcus granulosus in Tunisia. A high degree of genetic similarity was shown between the cysts of the three host origins. Nevertheless, whereas, the ovine and human samples were highly similar, the cattle samples were slightly different genetically.

Balloon dilatation of anastomotic strictures secondary to surgical repair of oesophageal atresia.

The purpose of this study was to evaluate the efficiency and safety of oesophageal balloon dilatation in strictures secondary to surgical treatment of oesophageal atresia in 25 children. Patients comprised 15 males and 10 females, aged 1-36 months. Median age was 4 months (interquartile range (IQR)=19).

Intrahepatic spontaneous portosystemic venous shunt: value of color and power Doppler sonography.

Spontaneous portosystemic venous shunts (SPVSs) within the hepatic parenchyma are rare. Fewer than 50 cases have been reported, and most of them were diagnosed by angiography. We present a case of SPVS diagnosed by color Doppler sonography in a 5-year-old boy admitted for bleeding due to rupture of esophageal varices.

[Subcapsular hematoma complicating acute pyelonephritis].

Spontaneous subcapsular renal hematoma is rare and essentially associated with malignant, or benign tumor vascular diseases, inflammatory processes. In few cases, no cause was detected. We observed one additional case in a diabetic women.

[Primary psoas abscess in children: 6 cases].

Background: Primary psoas abscess is very rare in childhood; its diagnosis and treatment can be improved by the use of recent imaging techniques.

Patients: Six children, aged 11 months to 10 years (mean: 51 months) were admitted from January 1987 to 15 December 1993 because they suffered mainly from fever, lumbar pain and/or homolateral flexed hip. Examination showed a painful inguinal mass in five patients and hyperleucocytosis in all.

[Posterior vertical lumbotomy in pediatric practice. Apropos of a series of 294 cases].

The study involves 294 cases. Essentials indications of posterior approach were for pelvic stones or lumbar ureteral stones 198 cases. Theres used this approach for abnormalities in the uretero-pelvic-jun (32 cases) and some staghorn srones (24 cases).
