[Testicular and paratesticular tumors in children].

Testis tumors in children occur infrequently and exibit differences in their histopathology, clinical behaviour and therapy from their adult counterparts. From 1979 to 1994, 17 children and adolescent with testicular tumors were treated at the Pediatric Surgical Department of Vicenza Regional Hospital. Paratesticular rabdomiosarcoma were present in 3 cases, 4 patients had embrional carcinoma, 1 Sertoli cell tumor, 2 Leydig cell gonadal stromal tumor, and leukemic infiltrates of the testis were clinically evident in 7 patients. We report our clinical series and discuss in relation to clinical characteristic, histopathology and therapy and conclude that the improved survival during the past decade is attributable to better diagnostic imaging thecniques, the availability of serum tumor markers to monitor disease activity and more effective chemotherapy.

[Retroperitoneal nodular fasciitis: analysis of a case].

A case of nodular fasciitis occurring in a 14-year-old girl is described and the clinical-pathological profile and the diagnostic problems are analyzed. The Authors believe this report useful to be reported for the relative rarity of the disease, especially in children, the very great dimension and the unusual retroperitoneal localization.

[Ovarian tumors in children].

Ovarian tumors in children are uncommon. We reviewed all cases of ovarian tumors treated at the Department of Pediatric Surgery of Vicenza Regional Hospital from 1979 to 1994. They include 6 cases of cystic teratoma and 1 gonadoblastoma; the malignant lesions included 1 immature teratoma, 1 dysgerminoma, 1 yolk-sac tumors and 1 patient with ovarian infiltration from malignant leukemia. Only the patient with leukemia died of progression of the disease. These data show that most ovarian masses are benign. Germ-cell tumors are the most common malignancy and epithelial cell tumors are less likely. Epithelial cyst and teratomas are the most common benign lesions. Although ultrasound was 100% accurate in the diagnosis of ovarian pathology, the ultrasonogram could not distinguish between benign and malignant lesions.

[Primary omental torsion in children: report of 2 cases and review of the literature].

The primary torsion of the omentum is a rare cause of acute abdomen. The clinic features may mimic closely acute appendicitis, with acute onset of right lower quadrant pain. The Authors, after reporting two cases recently observed, discuss the aetiopathogenetic aspects, point out the problems of diagnosis and finally suggest the most correct surgical approach.

[Cryptorchidism with didymo-epididymal dissociation and Robinow's syndrome: 2 case reports].

Two brothers of normal not consanguineous parents, with bilateral intrabdominal cryptorchidism, were admitted to our Institution. Both children had short stature, limb and hand malformations and craniofacial patterns of Robinow syndrome. During the orchidopexy, bilateral epididymal and vasal abnormalities were found in both of them. This anomaly associated with Robinow syndrome has never been reported before. These two cases provides the Authors with the opportunity of reviewing clinical features, genetics and radiological patterns of this rare syndrome.

Seroepidemiologic study of HCV genotypes in the district of Messina and Catania.

Aim of the study was to identify the different hepatitis C virus (HCV) genotypes in chronic hepatitis patients living in the districts of Messina and Catania (Sicily, Italy), for epidemiological reasons but also to determine the effect of interferon therapy on therapeutic response of different viral genotypes. Genotyping was carried out by reverse-hybridization after amplification by polymerase chain reaction. The study was conducted on 271 patients with HCV-RNA positive chronic liver disease belonging to categories at risk or not for infection. HCV genotype sub-type 1b was the most common viral genotype identified.
