Background: Elevated concentrations of eosinophil cationic protein (ECP) have been found in acute viral wheezing during infancy. Furthermore, RSV infection has been suggested to stimulate type-2 cytokine responses. The aim of this study was to test whether serum ECP and soluble CD23 levels, which are markers of eosinophil and IgE responses, respectively, are elevated in infants hospitalized for acute respiratory syncytial virus (RSV) bronchiolitis., Material/methods: Fifty-five infants aged 1-12 months (median: 4.2 months) consecutively hospitalized for acute bronchiolitis were divided into two groups: RSV-positive (n=26) and RSV-negative patients (n=29). Serum ECP (s-ECP), soluble CD23 (sCD23), and total IgE were measured in all patients and in 23 asymptomatic infants (controls)., Results: Lower s-ECP levels were detected in the RSV-positive group (5.4+/-4.3 ng/dl) compared with controls (9.38+/-5.95 ng/dl, p=0.02), but they did not differ significantly from the values of RSV-negative patients (7.8+/-5.7 ng/dl). There was a trend to higher s-ECP values in patients with a positive family history of atopy and/or a history of atopic dermatitis in the RSV-positive group (p=0.06). No differences in sCD23 and total IgE levels among the groups were detected. No correlation between total IgE and sCD23 values was observed., Conclusions: There is no evidence from our data to suggest that either RSV-positive or RSV-negative acute bronchiolitis is associated with significant eosinophil-mediated degranulation. There is no evidence from the sCD23 data to support the hypothesis that IgE antibody responses are prominent during the acute illness.

Human echinococcosis is still endemic in some areas of the world, including Mediterranean countries. Because there is no effective medical therapy, surgery remains the principal mode of treatment. A consecutive of 132 patients operated on for liver hydatid disease between January 1977 and February 1993 were analyzed. There were 60 men (45.4%) and 72 women (54.6%) aged 31 to 88 years (mean 56 years). The right lobe of the liver was affected in 68 cases (51.5%), the left lobe in 31 cases (23.5%), and both lobes in 14 cases (10.6%); there were multiple liver cysts in 7 cases (5.3%), concomitant cysts in other parenchymal organs in 4 cases (3.0%), and disseminated intraabdominal hydatid disease in 8 cases (6.1%). Clinical symptomatology consisted of abdominal pain, fever, jaundice, urticaria, and an abdominal mass. Preoperative diagnosis was established using imaging studies: plain abdominal films, ultrasonography, computed tomography, and serologic tests. Three patients (2.3%) underwent simple closure without drainage, 7 patients (5.3%) cyst excision, 4 patients (3.0%) marsupialization, 1 patient (0.8%) left lateral segmentectomy, 15 patients (11.3%) external drainage, 69 patients (52.3%) omentoplasty, and 33 patients (25.0%) combinations of procedures. Postoperative morbidity was low and consisted of hepatic abscess development, wound infection, bowel obstruction, and biliary leaks. Six patients (4.5%) had recurrent disease. One patient died during the postoperative period because of septic complications. Among the surgical techniques we used, excision of the cyst (when feasible) and omentoplasty produced the lowest complication rates and the best clinical results.

A group of 26 patients with pelvic fracture and disruption of the prostatomembranous urethra were evaluated for impotence. Impotence was defined as inability to achieve an erection firm enough for vaginal penetration. Of the patients 25 were potent before the injury, whereas 1 was only 7 years old at injury. Seven patients admitted to being potent after the injury but before the final urethral anastomosis. Four patients became potent after urethroplasty. The definitive operation to the urethra was done approximately 6 months after the injury. Only 11 of the 26 patients (46%) reported erections adequate for vaginal penetration. No patient who had adequate erections before urethroplasty became impotent postoperatively. We believe that the impotence was caused by damage to the neurovascular supply to the penis at injury.

The effect of omental wrapping on the safety of intestinal anastomosis was studied experimentally in 12 dogs. In six animals serving as controls, complete division of the small intestine and immediate restoration of continuity was carried out, after rendering the intestinal segment ischemic by ligating the mesenteric vessels for a distance of 10 cm. In a second group of animals, the ischemic anastomosis was wrapped with a pedicled strip of omentum. Gangrene and peritonitis developed in all animals of the control group, whereas the omental graft afforded complete protection against leakage from the devascularized anastomosis and peritonitis in the test animals.

Thyroid diseases in children and adolescents are not common. The present paper describes 73 patients, aged 5 to 18 years, who had thyroid disease which was treated by surgery. Of these, 18 had diffuse simple goiter, 11 had diffuse toxic goiter and 44 had nodular goiter. Of those patients with nodular goiter, 34 had adenomatous goiter, one had lymphocytic thyroiditis, one had lymphosarcoma and eight had cancer. In the patients with nodular goiter under the age of ten years, 40% had cancer, and of those aged 11 to 18 years, 14.7% had cancer. Thyroid nodules were more frequent in girls than in boys, but the incidence of cancer in nodular goiter was higher in boys than in girls.
