The authors report a retrospective study of therapeutic abortions for antenatally diagnosed abnormalities, 146 fetuses are concerned during a five years period, an anatomo-pathological examination have been performed in all cases, malformations of central nervous system are the most frequent (62). 26 urologic abnormalities are especially detailed. There are 10 isolated urologic abnormalities, and 16 abnormalities multiples. All fetuses had renal lesions which could justified an intervention but the declaration at registration of congenital birth defects is not obligatory. A multidisciplinary approach to prenatal diagnosis and congenital birth must still developed for a better understanding.

This work tries to clarify the place which is due to the modified Lyons orthopaedic treatment of scolioses. Actually, nowadays, because of progress in surgery, some people abandon all orthopaedic treatment which caught severe progressive scolioses at the end of the growth period. The study covers 70 patients from a minimum distance of 3 years after the end of orthopaedic treatment. The treatment, in comparison with the classical Lyons treatment has two principle modifications: sequence protocol plaster then corset, purely external, not necessitizing hospitalisation or a stay in a specialised centre; and the use of resine which lightens the plaster. The results are given in angular loss as regards to the end of treatment, according to 3 factors; chronological form of the scoliosis, localization of the scoliosis, degree of the initial curvature. It emerges that in spite of the absence of hospitalisation at the beginning of the treatment, the results are comparable to those in literature (8, 19). We obtained 39 stabilizations of progression, 8 moderate aggravations without ulterior surgery, that is 67% good results. Our study confirms the high failure rate of orthopedic treatment of initial scolioses of 50 degrees and more (50%); compared to initial scolioses of 49 degrees to 20 degrees (29%); of dorsal scolioses (42%) compared to lumbar scolioses (18%); of child scolioses (40%) compared to adolescent scolioses (17%). It leads us to keep the Lyons treatment for progressive scolioses of 25 degrees to 40 degrees, from the start of puberty, or as preparation for surgical treatment.

Three cases of diffuse esophageal leiomyomatosis are discussed. Two of these are familial one, the mother being affected. These familial cases can occur in association with Alport's syndrome. The occurrence of a case of esophageal leiomyomatosis imply a familial survey and the search of a renal or ocular disease. The surgical treatment of this affection in sub total oesophagectomy with esophageal substitution (with the colon especially). The long term prognosis is unknown, with the risk of renal failure if Alport's syndrome is associated or of other leiomyomatous localisation.

The authors report 3 new cases of Male Internal Pseudohermaphrodism. It is a scarce entity. The discovery is fortuous during the cure of hernia or cryptorchidism. The family history has nothing particular. The main problem of this syndrome is its treatment. Our attitude consisted in conserving the mullerian derivatives and treating the hernia or the cryptorchidism. Hysterectomy is not justified for the following reasons; no case of cancerisation of the mullerian derivatives has not yet been reported. The vasa deferens and uterus are in intimate relationship; the dissection is therefore dangerous. We did not perform systematic castration in order to protect fertility. The removal of the testis is performed only when the gland is intraabdominal and undescendable considering the major risk of cancerisation.

Thoracic trauma is uncommon in children. It should not be managed any more as adult's trauma. We present our experience with 85 children form 1 to 16 years of age, presenting severe thoracic trauma treated in Lausanne, Switzerland, between 1976 and 1990. The specific features of diagnosis, treatment and outcome are presented. Most of them were involved in traffic accidents (62%), 55% had multisystemic injuries. The mortality rate was not a function of the Injury Seventy Score as in adults, but was only related to the Glasgow Score. Only 3 patients (3.5%) had hemodynamic instability on admission in relation with their thoracic injury. Patients with intrathoracic lesions showed dyspnoea (65%), cyanosis (25%), or clinical suspicion of a pleural effusion or a pneumothorax (47%). However 12 children had an asymptomatic severe thoracic injury. In 53 patients (62%) the auscultation was found abnormal either with absent or diminished breath sounds or other pathological findings. 10 out of 26 cases of pneumothorax could be suspected by percussion dullness. Chest X-rays showed a lesion in 76% of cases. Only 30% of the pneumothorax were associated with visible rib fractures. 10 children suffered from 4 to 12 fractures of the ribs (mean 6.6). None of these patients presented a flail chest as in adults, even when multiple rib fractures existed. 31 thoracic drainages were performed, during a mean period of 3.3 days. 30 patients were intubated and ventilated, 22 of these due to a neurosurgical condition. All patients had physiotherapy starting on day 2, under analgesia if necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

We here present a review of ten pediatric patients with rib tumors that were treated in our hospital since 1970: a juvenile bone cyst, an aneurysmal bone cyst, an eosinophilic granuloma, a Ewing sarcoma, a metastasis of a neuroblastoma, an osteochondroma, a hemangiopericytoma, and a callous tumor at the site of a previous single rib fracture. The relative frequency of rib tumors is similar to that of bone tumors in other locations. A biopsy of the affected bone should be the first step of the operative intervention. As demonstrated in a case of eosinophilic granuloma, the indication for subperiosteal rib resection can be defined generously. A completed regrowth of the rib defect can be expected. Even the loss of a complete rib is generally well tolerated, as shown in an infant with an aneurysmal bone cyst, a rare disease in this age group. Malignant tumors of the chest wall, however, require special experience in thoracic surgery and necessitate close interdisciplinary cooperation. Complete primary resection of a malignant rib tumor and its plastic reconstruction is demonstrated in a case of a Ewing sarcoma in childhood. In children and adolescents a vicryl net should generally be used to reconstruct extended chest wall defects reliably and functionally stable.

Ninety-four cases of limb vascular traumas were observed in children during a 25 year-period. Treatment was done less than 12 hours after the injury in 83 cases, later than 24 hours in 7 cases. Superior limbs were more often concerned than inferior limbs: 65 vs 29 cases. Bone lesions were found in 34% of cases, articular lesion in 12% and neurological lesions in 40%. Vascular repair was necessary in 63 cases, mostly by suture (41 cases) or venous graft (16 cases). Two patients died because of associated polytrauma. In 8 cases, anatomical and functional results are good, but follow-up is short. In 65 cases, results were initially satisfactory; 5 patients had later complications leading to sequelae in 3 cases. In 19 cases complications occurred and led to amputation in 5 cases; among the remaining 14 patients, results were finally satisfactory in 9 cases and sequelae were observed in 4 cases. Early diagnosis problems and treatment are discussed. Associated lesions have to be taken into account to assess the results.

Recent trends in the management of pediatric solid-tumors have resulted in reducing the scope of surgery. In the therapy of RMS of the orbit, genitourinary tract, head & neck and trunk & extremity sites, regimens of primary chemotherapy/radiotherapy have replaced, reduced or delayed excisional surgery. In some sites, these approaches have been successful. In others, a return to a more active surgical approach may be indicated, as observed in two studies noted below. Results of a primary chemotherapy approach for vesical RMS have been disappointing, as noted in the Intergroup Rhabdomyosarcoma Study (IRS) (U.S.) in which the mortality is greater than 25% and rate of bladder salvage among survivors less than 45%. Partial cystectomy for RMS was justifiably condemned prior to the development of effective chemotherapy, but deserves reevaluation. Partial cystectomy with adjunctive chemotherapy was performed in 33 children, 21% of the total pts with vesical RMS in the IRS. In 27 of these patients, it was carried out as the initial operation. Six additional patients had tumors which responded to chemotherapy, and a secondary partial cystectomy was performed. The mortality among these patients has been the same as in the overall group of patients with primary bladder tumors. The retention of functional bladders, however, has been greater than 95% among survivors with only 1/26 bladders lost to contracture. All patients (4) in this group who had postoperative functional vesical problems received more irradiation than is currently recommended. In this study, the use of partial cystectomy has been confined to cases in which it would obviously be successful.(ABSTRACT TRUNCATED AT 250 WORDS)

Trough two cases of Sternopagus, study of classification of conjoined twins with precise definition of anatomic characteristic of Sternopagus. Description of our own subject and review of literature. At the end of this study, it is evident that the heart and vascular fusion is always complicated. So, the true Sternopagus are inseparable and no likely to live, in opposition with Xiphopagus and Thoracopagus.

Cyst or intestinal duplications can arise anywhere along the gut, however those located in the rectum are very rare and only a few dozen cases have been reported. The reason that induced us to report this patient is double: first to present a new case of rectal duplication diagnosed at 45 days old that had a normal barium enema previously, second to confirm once more that the muscular complex of the rectum can be cut in the posterior middle line without any damage to the rectal continence function, as Peña's surgical approach for anorectal atresias. The case reported correspond to a newborn weighing 2,850 grs who had exomphalos of 5 cm. Wide with an integral sac and was operated by primary closure. When he was 10 days old, and because he had some intestinal disturbances compatible with malrotation, a barium enema was done that was normal. He was discharged and returned 30 days later because of striped feces and constipation. Rectal examination showed a retrorectal tumor located at left posterolateral space. Ultrasound showed a cystic mass and barium enema displayed a narrowed rectum channel. First we did a Wangesteen colostomy. Ten days later, by a sagittal posterior approach cutting the Levator and Muscular Complex of the rectum in the middle line and without opening the lumen, a tumor like a nut, sharing its muscular coat with the rectum, was excised. The Muscular Complex and the Levator were repaired with the aid of the electrostimulator. After the 7 day postoperation we made some rectal dilatations and closure of colostomy at 21 day.(ABSTRACT TRUNCATED AT 250 WORDS)
