The Kalicinski ureteral folding technique for megaureter in children. Experience in 23 cases.

We report our series of 16 children with 23 megaureters: 7 were refluxing, 11 were obstructive (7 primary and 4 secondary), 3 both refluxing and obstructive and 2 nonrefluxing nonobstructive. These patients had a Kalicinski folding-under remodeling of their megaureter and Cohen or Lead-better reimplantation. Success rate was 96% with only 2 failures: 1 recurrent low-grade reflux treated with subureteric Teflon injection and 1 stenosis that necessitated reoperation. Kalicinski's technique with Cohen type reimplantation is one of the best alternatives for megaureters, mainly because it does not present the disadvantages of the excisional procedure.

Congenital esophageal stenosis.

We report 6 new cases of congenital esophageal stenosis (CES) that presented to us with special diagnostic and management problems and review the literature on this subject. Gastroesophageal reflux and achalasia are important differential diagnoses of esophageal stenosis, they may be associated with CES making appropriate management even more difficult. Treatment is also controversial, ranging from simple dilatation to segmental resection. CES should be present in every pediatric surgeon's mind should dysphagia occur on the introduction of semisolid food or esophageal food impaction, with a segmental stenosis demonstrated at esophagogram even when more obvious diagnoses are evoked.

Congenital cyst of the pancreas. Antenatal diagnosis.

We hereby report the third case of antenatal diagnosis of congenital cyst of the pancreas. It is a very rare lesion and could present as a differential diagnosis of any intra-abdominal cystic mass. Early treatment is easy and prevents complications such as ascites and pancreatitis in case of intra-pancreatic enteric duplication.

[Treatment of severe and recurrent hypospadias. Personal experience in thirteen cases].

The treatment of severe and recurrent hypospadias includes different techniques. We present thirteen cases (7 recurrent and 1 circumcised). In four recurrent cases of midshaft hypospadias, we chose Mathieu's technique, and in nine severe cases, three of them were recurrent cases, Duckett's technique (3 cases), free bladder mucosal graft (4 cases), and free prepucial mucosal graft (2 cases). Our results were good in 9/13 cases (70%) with three fistulas, two of them were cured as out care patient. We try to precise each technique indications and details which would lessen the postoperative complications rate.

Congenital prepubic sinus.

We report the fifth case of congenital prepubic sinus that goes from the anterior wall of the bladder through the public symphysis to the skin. The various embryological theories that could be responsible for this pathology are discussed, and according to us, it seems to be a variant of dorsal urethral duplication.

[Wilms' tumors, 12 case reports].

The treatment of Wilms' tumor has shown a great success in the pediatric oncology. Our study, which includes 12 cases of nephroblastoma, between 1979 and 1987, has confirmed this results. This tumor that shows no sex prevalence, occurs in a mean age of 2.5 years. The volume of the mass is the most presenting sign in 75% of the cases, I.V.P. confirm the diagnosis in 90% of the cases. Remission occurred in 5 infants who have been in stage I, the other cases who are in stage II to V have bad prognosis. In the future, we hope more advancement in the cure of Wilms tumor, and all the remaining questions will find their answer.

Effect of dimethyl sulfoxide on blood-to-brain transfer of alpha-aminoisobutyric acid: examination of regional blood-brain barrier function.

The effect of dimethyl sulfoxide (DMSO) on brain capillary permeability has been controversial. We have studied the effect of DMSO on unidirectional transport of alpha-aminoisobutyric acid (AIB) across the blood-brain barrier (BBB) in rats. Rats were treated with 15% DMSO intraperitoneally (i.p.), intravenously (i.v.) or by an i.p. injection in combination with an i.v. injection, or in some cases intra-arterially by rapid infusion into left external carotid artery. The unidirectional blood-to-brain transfer constant (Ki) for AIB was measured in each group after the animals were killed. DMSO administration did not significantly increase Ki as compared to control Kj. These results show that it is unlikely that DMSO increases the permeability of BBB and therefore do not support the proposal that DMSO can act as a carrier at the BBB for compounds with restricted vascular permeability.
