Adnexal tumour of probable Wolffian origin. Report of a case.

An adnexal tumour of probable Wolffian origin occurring in a 36 year old woman is reported. The lesion was asymptomatic and incidentally discovered during laparotomy. No recurrences have been demonstrated to date.

[Percutaneous transluminal angioplasty on the solitary kidney. Report of a complicated case of renovascular hypertension].

We report a complicated case of renovascular hypertension from bilateral atherosclerotic renal artery stenosis in a solitary functioning kidney. Percutaneous transluminal angioplasty (PTA) was performed after diagnostic arteriography. Hypertension remitted only after surgical removal of the nonfunctioning kidney.

Congenital mesoblastic nephroma, nephrocalcinosis, and hypertrophic pyloric stenosis.

A cellular variant of congenital mesoblastic nephroma (CMN) occurring in a newborn is presented. Coincidental findings were congenital hypertrophic pyloric stenosis (CHPS) and nephrocalcinotic hypercalcemia that reverted after nephrectomy. As of the day of writing, this multiple association has not been reported.

[Practical precautions in urology against the human immunodeficiency virus].

As infection from HIV spreads, the features of the population at risk change. In fact, we have been treating more cases with different features. Numerous studies have been published in the medical literature aimed at making the health staff aware of the need to take precautions while caring for these patients, most of whom are HIV infected but apparently healthy.

Long term survival in metastatic nephroblastoma. A case report.

We describe a case of metastatic nephroblastoma presenting as renal rupture. Histology was "favorable". Lung metastases were discovered early during follow-up.

[Giant hydronephrosis with an unusual angiographic pattern].

The paper describes an unusual angiographic pattern within the context of stenosis of the pyeloureteral union and giant hydronephrosis of the adult, with a presumed congenital origin. From the embryonic point of view we discuss the remote possibility of this being a real "agenesis" of the renal artery with no agenesis of the kidney, irrigated by multiple segmental arteries following the characteristic metamerism of the mesonephros. On the other hand, it seems more consistent to explain such vascular pattern as an image of severe atrophy, in correlation with the hydronephrosis advanced stage, and not as a primary congenital defect.

[Nephro-urologic manifestations of the acquired immunodeficiency syndrome in our country].

We intend to approach the genitourinary and nephrological pathologies presented in our environment by patients with HIV infection. To this end we have carried out a retrospective study on a series of patients selected on the basis of follow-up possibility. A continuous history, recording a detailed clinical examination including repeated sampling and serological testing, would allow us to stress the relevance of hidden urological pathologies which these patients rarely complain about.

Kaposi's sarcoma of the penis as an initial urological manifestation of AIDS. A report of two cases.

Kaposi's sarcoma of the penis is an initial manifestation of AIDS and the practising urologist should be aware of this form of presentation. We report 2 young intravenous drug abusers with this tumor in the male genitourinary system. The clinical course is unfavorable; therefore prompt diagnosis and management, based on the early recognition of the lesion, must be achieved.

Metastasising carcinoma of the urinary bladder presenting as a retro-orbital mass. Case report.

A 61-year-old man presented with macroscopic haematuria. Infiltrating transitional cell carcinoma of the urinary bladder was diagnosed after transurethral resection, and he was treated first with three doses of cisplatinum (100 mg/m2 at three week intervals) and then by radical cystectomy. Eleven months later he complained of progressive diplopia, which was found on computed tomography to be caused by a retro-orbital metastatic mass.

Bladder transitional cell carcinoma.

We present a case of urinary bladder carcinoma in a child aged 13 that followed a benign course. This confirms the idea that epithelial bladder cancer in children pursues, a much less aggressive behaviour than in the adult, possibly on the basis of its well-differentiated nature. Despite the rarity of the lesion, it should not be overlooked in the differential diagnosis of haematuria in children.

Hydrops fetalis and congenital mesoblastic nephroma.

The autopsy finding of congenital mesoblastic nephroma in a stillborn hydropic fetus is reported. We discuss the pathogenetic relation of both entities and summarize the optimal therapeutic attitude to follow in order to prevent this misfortunate outcome.

[The immotile cilia syndrome as a cause of sterility].

We investigated the relationship between ciliary dyskinesia--commonly referred to as inmotile cilia syndrome--and sterility. In the past two years, we have accurately diagnosed 6 new cases of a total of 20 suspected as having this condition. To make the diagnosis, complete clinical, radiological, ultrastructural and spermatic work up was performed.

Study of various immunological parameters in the diagnosis of allergy to penicillin G and its derivatives.

The objective of this paper was to draw up an efficient and safe study protocol to diagnose allergy to beta-lactam antibiotics. Seven hundred and fifty patients with clinical histories suggesting penicillin allergy were studied. RAST to penicilloyl G/V, skin tests with PPL, MDM, penicillin G and ampicillin, epicutaneous tests with differed type reactions and a provocation test (in case of the negative results of the other tests) were performed on the patients.
