[Polyp of the posterior urethra in boys (author's transl)].

A rare case of posterior urethral polyp associated with acute urinary retention in a boy 22 mo. old is presented. The symptomatology, diagnosis and treatment are discussed and the literature is reviewed. Micturating cystogram is considered to be of definitive aid in the diagnosis as endoscopy alone may be misleading.

HIV, HBV, delta-agent and Treponema pallidum infections in two rural African areas.

In order to compare the seroepidemiology of human immunodeficiency virus (HIV), hepatitis B virus, delta agent and Treponema pallidum infections in two rural populations living in north Uganda (Kitgum district) and in central Burundi (Butezi, Ruyigi region), 448 sera were tested for HBS-Ag, HBS-Ab, and anti-HIV antibodies and screened for syphilis using the T. pallidum haemagglutination (TPHA) test. HBS-Ag positive sera were also tested for anti-delta antibodies. Overall seropositivity rates in healthy subjects, outpatients and inpatients (non-AIDS) were 14.2% and 9.5% in Kitgum district and Butezi, respectively. The prevalence of HBS-Ag and HBS-Ab ranged from 10.0% to 15.6% and from 66.2% to 68.9%, respectively. In north Uganda the rates of anti-delta positivity were 3.1% in the overall population and 30.6% in the HBS-Ag positive subjects. No serum obtained in Butezi was anti-delta positive. In Ugandan people, 64.0% of anti-HIV positive and 25.8% of anti-HIV negative patients were also TPHA-positive (P less than 0.01). For Butezi the corresponding figures were 21.4% and 1.6% respectively (P less than 0.04). On the contrary, no correlation was found between either anti-HIV or TPHA positives and seropositivity for B and delta hepatitis serological markers. The study demonstrated an association between seropositivities for HIV and T. pallidum (TPHA), suggesting common patterns of transmission. On the contrary, no association seemed to exist between HBV and HIV infections.

[Follow-up study of pulmonary function in individuals subjected to lobectomy in infancy and childhood].

Experimental research in animals have demonstrated that pulmonary development continues after birth. This happens in man as well: alveolar proliferation and enlargement go on until the eighth year of age, furthermore complete pulmonary development is achieved until the 20-22 years of age. It is therefore possible to hypothesise that respiratory deficit following pulmonary exeresis in children would regress with time. In the Pediatric Surgery of IRCCS Policlinico S. Matteo of Pavia eight children, 4 days to 8 years of age, underwent lobectomy for pulmonary hypertensive emphysema (3), lung abscess (2), bronchogenic cysts (2) and hystiocytoma (1). One of them was lost to follow-up; the remainders were controlled from 3 to 25 years after surgery: all of them enjoy a normal active life. Respiratory function was evaluated through blood chemistry, blood gas analysis, basal and after strain ECG, chest X-ray, spirometry, basal and after strain pulmonary scintigraphy. Basal and after strain ECG, chest X-ray, and arterial blood gas were normal in every examined subjects; spirometry, although results are quite variable, did not show serious respiratory deficits; basal after strain pulmonary scintigraphies weren't homogeneous. These results, although they aren't univocally interpretable, positively confirmed that the residual lung after lobectomy has a satisfactory possibility of functional recovery.
