Arteriomesenteric syndrome as a cause of duodenal obstruction in children with cerebral palsy.

Two cases of gastroduodenal outlet obstruction caused by arteriomesenteric compression in children who have cerebral palsy are reported. Clinical symptoms of gastrointestinal obstruction include recurrent postprandial nausea and vomiting, upper abdominal distension, and pain. In such patients, multiple predisposing factors can contribute to the development of arteriomesenteric compression, including marked weight loss, supine position, and severe scoliosis. Upper gastrointestinal x-rays using barium contrast allow diagnostic confirmation. In our experience, this cause of acute gastroduodenal outlet obstruction may usually resolve after conservative treatment using a jejunal feeding tube passed beyond the compression, left lateral positioning, and renutrition.

Hirschsprung's disease: a 20-year experience.

During the period from 1972 to 1992, 59 children received surgical treatment at the University of Louvain Medical School for biopsy-proven Hirschsprung's disease (HD). The extent of aganglionosis was as follows: short segment restricted to the rectosigmoid or descending colon (n = 44, 75%); long segment (n = 9,15%); ultra-short segment (n = 3, 5%); unknown length because of death without autopsy (n = 3, 5%). The median age at operation was 7 months for short-segment disease compared with 14 months for those with long-segment disease. Surgical procedures used for short-segment disease were Swenson with colostomy (n = 16), Swenson-Pellerin without colostomy (n = 27), Duhamel (n = 1), and for long-segment disease were Martin (n = 3), Swenson-Deloyers (n = 2), Swenson-Boley (n = 2) and ileostomy only in = 2). Lynn's sphincteromyotomy was performed in the three ultra-short cases. There were six deaths (10%) at a median age of 86 days (range, 28 to 1545 days), three had long-segment disease, and the others were not classified because of death before curative surgery. Enterocolitis (EC) was the most common cause of death (five cases) and was also the major source of morbidity after curative surgery (12 of 44, 27%) in short-segment patients, three of seven (43%) in long-segment patients. The functional success of the procedure was evaluated in 70% of the surviving patients (37 of 53; mean follow-up, 8.7 years; range, 1.2 to 21.5), using a novel semiquantitative scoring system, specifically designed for children who have HD. This system assesses normal stool evacuation, abdominal distention, soiling, and severe incontinence. The results were compared with those from a population of 39 healthy children and adolescents and demonstrated progressive improvement in function during childhood and adolescence (P = .04) for patients treated for short-segment disease. However, function was found to be consistently poorer in all age groups when compared with healthy controls (5 to 10 years, P < .01; 10 to 15 years, P < .05; > 15 years, P < .01).

Megaureter in childhood: conservative or surgical management?

Antenatal and incidentally diagnosed megaureters can be safely treated conservatively after careful work up by combined imaging technics. Serial and repeated imaging are non the less usually necessary to confirm the diagnosis. This aspect could be fastidious and expensive. In case of symptoms, breakthrough infections or loss of kidney function, surgical treatment should be considered and good results can be expected. Refluxing megaureter has to be considered as high grade reflux and surgical approach is more often suggested. The authors have reviewed the experience of 139 patients with megaureters treated in the last decade to illustrate those facts.

Madelung deformity as a feature of the Leri-Layani-Weill syndrome or dyschondrosteosis.

We report and discuss a case of a Madelung's deformity seen on a wrist roentgenogram of a young girl who is referred for short stature evaluation, which led to the diagnosis of Léri-Weill syndrome or dyschondrosteosis. The authors stress that it is possible to make an accurate diagnosis on a single standard roentgenogram, at low cost, if the different diagnostic criteria are known.

Primary calcification in post-transplantation lymphoproliferative disorder involving the hepatic graft: an exceptional finding.

Calcification within active post-transplantation lymphoproliferative disorders has, to our knowledge, never been described. We report the case of a 14-month-old boy who presented 4 months after orthotopic liver transplantation with a primary calcification in a lymphoproliferative nodule involving the hepatic graft. This calcification was detected by routine ultrasonography, visible on plain radiographs, and the post-transplantation lymphoproliferative disorder was histologically proved.

Radiographic skeletal survey and radionuclide bone scan in Langerhans cell histiocytosis of bone.

BACKGROUND: The lack of a consensus in the literature on the imaging strategy in Langerhans cell histiocytosis (LCH) bone lesions in childhood. OBJECTIVE: To evaluate the relative value of radionuclide bone scan (RBS) and radiographic skeletal survey (RSS) in the detection of LCH bone lesions, both in the initial work-up of the disease and during the follow-up period. MATERIALS AND METHODS: Ten children with bone lesions evaluated by means of RSS and RBS in a retrospective study (1984-1993). RESULTS: Fifty radiologically and/or scintigraphically abnormal foci were detected: 27 anomalies in the initial work-up (12 by both RSS and RBS, 8 by RSS only and 7 by RBS only) and 23 additional anomalies during follow-up (10 by both RSS and RBS, 10 by RSS only and 3 by RBS only). RSS+/RBS- lesions (n = 18) are more frequently encountered in the skull (P = 0.038), and more frequently lack radiologic signs of osteoblastic activity (P = 0.020), than RSS+/RBS+ lesions (n = 22). RSS-/ RBS+ abnormalities (n = 10) were most frequently insignificant. CONCLUSION: In the initial work-up both RSS and RBS should be carried out, while in the follow-up only RSS should be performed.

A new familial short stature syndrome: Brussels type.

A new association of congenital familial short stature with facial dysmorphism and osteochondrodysplastic lesions is described in two siblings. Clinical abnormalities include severe prenatal and postnatal growth failure and facial dysmorphism. Radiographs show osteochondrodysplastic lesions with a narrow thorax, short ribs, epiphyseal maturation delay and slightly deformed metaphyses. Microscopic analysis of the skeleton shows pathological features.

[Treatment of hypospadias: 15-year experience].

Numerous hypospadias correction techniques were described in the literature. The technique varies according to the position of the meatus and the importance of the chordee. These new techniques and the care taken in the manipulation of the tissues tend to decrease complications like stenoses and fistulas, frequent in the long urethroplasty. The correction of hypospadias should conform to aesthetic and plastic surgery. More than 300 corrections were carried out in our service. Surgical technique varied in the long run. Currently, we choose as often as possible a correction in one time: release of the chordae and urethroplasty. Straightening of the penis is obtained on one hand by release of the cutaneous chordae and wide dissection of the hypoplastic urethral plate and one or more dorsal plications according to Nesbit are carried out if it proves necessary. In the distal, glandular and coronal forms, the correction is of type M.A.G.P.I. (meatal advancement, glanduloplasty). The complication rate is extremely low. The aesthetic and functional result is very satisfactory. In the proximal forms, Duckett technique is used only in the obligatory cases given the large number of complications. It is generally replaced by Onlay technique. The urethral plate is left in continuity and serves as support to the pedicled and vascularized flap. In the intermediate situations with a middle shaft hypospadias, Mathieu technique is again of application. The aesthetic and functional result of this type of surgery requires good knowledge and careful application of the technique adapted to each case.

[Quality control in pediatric radiology].

The authors recall the fundamentals of an adequate use of the X-rays considering to the ALARA (As Low As Reasonably Achievable) principle. The article deals more specifically with radiation protection and quality control in radiopediatrics, as this age group is essentially concerned with stochastic hazards, i.e. cancer induction and genetic injurious effects. The major elements of X-ray equipment are reviewed, including the X-ray generator, device, film-screen, radiogenic tube, automatic exposure device, and so on... The influence of technical parameters on dosimetry in terms of radiation protection as well as dosis variation, according to the type of disorder, are demonstrated. Reference is made to the radiologic techniques proposed by the Lake Starnberg Group.

[Epipadiac duplication of the urethra].

Urethral duplication is a less frequent malformation. The Williams classification, which is currently admit, classifies them in sagital, hypospadias or complex and collateral duplications. They can be complete, incomplete or reduced to an incomplete sinus. The most severe cases are often accompanied by multi-abnormality syndromes. Clinical manifestations are various: asymptomatic, urinary infection, incontinence, double urinary stream,... We will report two new cases of incomplete epispadias duplication. The first case presents a purulent flow from the fistula, the second a frank epispadiac status. In both cases, corrective surgical treatment was performed, after a complete balance-sheet. The embryological, diagnostical and therapeutical aspects of the different forms of urethral duplication will be studied based on data from literature.

[Laparoscopic treatment of recurrence and embolization failure of varicocele].

Varicocele is a benign pathology, for which the less invasive treatment is percutaneous embolisation. Literature reports results from 70 to 85% (1,2). Laparoscopic treatment seems to be a good alternative for patients suffering from a recurrence, or patients who can not be embolised. We report our experience concerning the first 13 patients treated with laparoscopic technic. In all 13 cases it was possible to practice the technic, and patients were cured.

Percutaneous transjugular intrahepatic stent shunt for treatment of intractable varicose bleeding in paediatric patients.

UNLABELLED: Two 10-year and 11-year-old children with oesophageal and gastric varicose haemorrhage unresponsive to medical treatment and repeated endoscopic sclerotherapy underwent percutaneous transjugular intrahepatic portosystemic shunting (TIPSS). A newly developed introducing system was used. The procedure was performed to avoid the increased risk of emergency liver transplantation in children with hepatic failure. Immediately after the procedure bleeding stopped and the patient's condition improved. Ascites disappeared and liver function improved. The stent shunt was shown to be patent by angiography and Doppler ultrasound for a follow up period of more than 1 year. CONCLUSION: TIPSS may be of benefit in children with severe portal hypertension. It allows control of intractable bleeding, and stabilizes the patients preparing them for subsequent elective orthotopic liver transplantation.

Sonographic evaluation of traumatic spinal cord lesions in the newborn infant.

We present a case of spinal cord injury due to birth trauma and assess the value of sonography for diagnosis, lesion characterization, and follow-up. Sonography is a non-invasive and easily reproducible imaging method for examining a ventilated child, and its initial sensitivity is comparable to that of MRI. Sonography is the method of choice for guiding diagnosis in this type of traumatic lesion to the newborn.
