[Cystic-papillary neoplasm of the pancreas: a case report in childhood]. / Neoplasia cistico-papillare del pancreas: descrizione di un caso in età pediatrica.

A solid and cystic tumor of the pancreas in a 11-year-old girl is reported. The child presented with abdominal pain and vomiting. A voluminous tumor, arising from the pancreas tail, was removed with distal pancreatectomy. These neoplasma occur predominantly in girls and young women, the prognosis is usually good in spite of histologic finding of apparent malignancy. The histochemical, immunohistochemical and electron examinations of this tumor show polymorphic differentiation, which means that part of the all can differentiate into duct epithelium, acinar or endocrine line. So up to, recently this tumor has been misclassified within other pancreatic tumors, and frequently has been managed with aggressive surgery. But as the neoplasm usually behaves like a very low grade malignancy, its complete removal is the treatment of choice for the tumors arising anywhere in the pancreas. The authors emphasize the importance of accurate diagnosis and of extirpative surgery in children with pancreatic malignancy.

[Retroperitoneal lymphangioma. Radiologic aspects and diagnostic protocol]. / Linfangioma retroperitoneale. Aspetti radiologici e protocollo diagnostico.

The authors analyze the radiological aspects and the staging problems of the retroperitoneal lymphangioma, a rare neoplasma of infancy. Echography and computer-assisted tomography contributions are particularly emphasized.

[Dilatation of esophageal stenosis using a balloon catheter]. / Dilatazione delle stenosi esofagee con sonda a palloncino.

Treatment of esophageal strictures is discussed. Authors describe technique and results of transluminal balloon dilatation in nine cases of esophageal stenosis.

[Hirschsprung disease. Results of surgical treatment]. / La malattia di Hirschsprung. Risultati del trattamento chirurgico.

The Authors report their experience in the treatment of 86 patients, in pediatric age, with Hirschsprung's disease: 40 with congenital rectosigmoid or subtotal megacolon, 8 with total colic or ileocolic aganglionosis and 38 with ultrashort aganglionic segment. Out of the patients 29% had necrotizing enterocolitis with 40% mortality rate in rectosigmoid or subtotal forms and with 75% mortality rate in total colic or ileocolic forms. In the last group the mortality was higher related also to difficulties and complications of surgical treatment. Necrotizing enterocolitis is the major cause of death in infants with Hirschsprung's disease. Early diagnosis and treatment can reduce the mortality rate.

Macroscopic hematuria associated with neonatal adrenal hemorrhage.

We report an unusual case of right adrenal hemorrhage in which none of the clinical or familiar factors commonly associated with this situation were present. Diagnosis was made after sudden macroscopic hematuria, and was based on clinical and radiologic findings alone. The normal course of adrenal hemorrhage is also discussed.

[Primary vesico-uretero-renal reflux. Results of surgical treatment in over 1,100 refluxing ureters]. / Reflusso vescico-uretero-renale primitivo. Risultati del trattamento chirurgico di oltre 1.100 ureteri refluenti.

Primary vesicorenal reflux (P.V.R.R.) is the most important cause in the pathogenesis of chronic pyelonephritis, better known in medical literature as "reflux nephropathy". The Authors stress out the criteria adopted in their Center for surgical treatment of P.V.R.R. and report the results in 1158 refluxing ureters (858 children) operated on. In 5 ureters an ureteronephrectomy and in 1153 remaining ureters and ureteral reimplantation was carried out. About 57% of ureters operated on was affected by severe reflux (IV - V grade). The Authors obtained 98.6% of surgical successes. In 16 ureters operated on, stricture (9 ureters) and reflux (7 ureters) were postoperatively present. The percentage of successes in infants less than 2 years old at operation was 98%.

[Gastroesophageal reflux update]. / Attualità in tema di reflusso gastro-esofageo.

Authors describe importance of anatomical and functional factors in ethiopatogenesis of G.E.R., diagnostic iter and methods. Importance of 24-hour computerized pH-metry in pediatric age is particularly stressed out. Medical and surgical therapeutic procedures are emphasized.
