[Vesicouterine fistula and bladder endometriosis. A case report].

Vesicouterine fistula is rare, accounting nearly 4% of all urogenital fistulas. Cesarean delivery through uterine lower segment is the main predisposing event but in the last years other possible predisposing factors have been pointed out. Clinically, it can occur in different forms and the diagnosis is often delayed although it is not difficult. In this study personal experience in a case of postcesarean vesicouterine fistula arisen on a focus of bladder endometriosis is reported and an eventual hypothetical pathogenetic correlation between bladder endometriosis and vesicouterine fistula is discussed.

[Role of Actinobacillus actinomycetemcomitans in human infection].

Actinobacillus actinomycetemcomitans (AA), is a cocobacillus thin and small, non motile, uncapsulate and capnophilic. AA, is: one of the species encountered in the mouth's comensal flora being able to be isolated in gingival crevices culture and oral mucosa in a 20% of the healthy population. An important number of pathogenic factors make it well equipped, to protect itself from host's defense mechanisms, and to destroy the periodontal tissue. Between the most important we find lipopolisacarides and leucotoxines which promote tisular invasion and destructive qualities of this microorganism. Since 1912, there are numerous reports of infectious process associated to it, between which we find: endocarditis in native and prothesic valve, soft tissues abscess, pneumonia, brain's abscess, urethritis, vertebral osteomielitis, thyroid's abscess, pericarditis and periodontal juvenile illness, being this one in which its isolation is more frequent. In vitro, AA is very susceptible to tetracicline. This antibiotic reaches high concentrations in gingival crevices, has significant affinity to the alveolar bone and contributes to protect the collagen. These special feature make them the election drug in periodontal disease produced by this microorganism.

Receptors mediating contraction of isolated human vas deferens.

A large body of evidences has suggested the role of adrenergic, opioidergic and other peptidergic receptors in the mediation of animal vas deferens motility. Different animal species showed different neurochemical patterns, so it is to be expected that human vas deferens has its own specific response to several substances, in relation to its peculiar function. In this study we report on the effects of monoaminergic (norepinephrine, dopamine, serotonin, isoproterenol, cholinomimetic drugs) and opioidergic (morphine, buprenorphin, beta-endorphin, met-enkephalin and dynorphin) agonists on isolated human vas deferens motility. Norepinephrine and dopamine provoked complex patterns of motility while opioids did not affect the field electroinduced contractions. The implications of this finding are discussed in relation to human vas deferens function.

[Liquid embolization of the renal artery with absolute ethanol].

Absolute ethanol is a new agent for use in embolization which has demonstrated excellent efficacy, is simple to manage, and above all is innocuous in case of reflux into the aorta. A part from provoking irreversible occlusion of the complete renal artery circle, embolization with ethanol provokes direct cellular toxic necrosis comparable with a true mummification. This is of fundamental importance during palliative embolization for renal cancer or in all cases of medical nephrectomy for non-neoplastic disease. Results of the use of liquid embolization of the renal artery with absolute ethanol are presented, the technique, described, and mechanisms of action analyzed based on histologic findings.

Fluoroscopically guided skinny-needle aspirative biopsy in normal and suspected lymph nodes in urologic cancer.

The authors present their experience with transperitoneal thin-needle biopsy of the retroperitoneal lymph nodes. This method is a means of improving lymphographic diagnosis in suspected lymph node metastases, the small contrast defects serving as a sign. The high rate of false-negative results makes its use unadvisable in patients with negative lymphography where the sample cannot be aimed at but is multiple and randomized.

[Percutaneous dilatation of renal artery stenoses. Apropos of 7 cases].

The authors report the results of percutaneous dilatation of renal artery stenoses, performed on 8 occasions in 7 patients. One patient had bilateral stenoses which were operated at two separate occasions. The authors had no complications and they confirm the stability of the results with a follow-up of up to 2 years. In the 4 cases with an isolated unilateral renal artery stenosis, dilatation of the artery led to normalization of the blood pressure within hours of the operation. When there was another cause for hypertension apart from the renal artery stenosis, the dilatation did not cause the blood pressure to return to normal, although the anatomical result was confirmed on arteriography. The authors then review the literature and compare the complications of surgery for renal artery stenoses with those occurring during or after percutaneous dilatation of the renal artery lumen. Because of the quality of the results, the complication rate and the good results obtained with percutaneous dilatation in the literature, the authors conclude that percutaneous dilatation of the renal artery lumen is the treatment of choice for these stenoses. The indication for this operation can be extended, as its aim is not only reduction of hypertension, but also to improve renal function and to avoid the risk of thrombosis on a very narrow stenosis. In this way, the indications for this operation extend to include a population which, up until now, has been excluded from surgery, such as elderly patients, patients with coronary disease, or with renal failure.

[Histological follow-up after implantation of grains of I-125 for prostatic cancer].

The authors report a preliminary study of 12 cases of carcinoma of the prostate confined to the prostate (T1, T2, T3, NO, MO) treated by pelvic lymphadenectomy and the implantation of grains of I 125 in the prostatic tissue. Irradiation continued for six months, providing most dose of 100 Gy in the prostate. Interstitial irradiation caused not only the destruction of tumour cells but also "radiation prostate" lesions with vascular obliteration which itself caused sufficient impairment of the vitality of the prostatic tissue for any residual tumour to disappear with a frequency which increased with the time elapsing between the follow up prostatic biopsy and the implantation of radioactive iodine. Experience remains limited but the initial figures given here suggest the validity of continuing along these lines.
