[Bone scintigraphy findings in patients with recently diagnosed adenocarcinoma of the prostate: relationship with prostate specific antigen levels].

BACKGROUND AND OBJECTIVES: Although it has been suggested that bone scintigraphy (BS) may not be necessary in patients with prostate adenocarcinoma (PA) and normal prostate specific antigen (PSA) plasma levels, controversy still remains. The objective of the study was to evaluate the existing relationship between PSA plasma levels and BS findings in patients with a recently diagnosed PA in order to assess whether BS may be omitted on the basis of the PSA levels in these patients. METHODS: The 475 patients (70+/-7 years old) consecutively diagnosed of PA between 1994 and 1998 in our institution made up the study population. PSA plasmatic levels were determined and BS was performed (body planar study after 99mTc-methyl diphosphonate 900 MBq administration) in all the patients. RESULTS: In 362 patients (76.2%), BS was negative, in 108 (22.7%) positive and undetermined in the remaining 5 patients (1.1%). The mean PSA level in the whole study population was 74+/-267 ng/ml (range 0.4-4.200) and was higher in patients with positive GO (218+/-512 vs 31+/-89, p<0,0001). As PSA increased, the rate of patients with positive BS was significantly higher, this being 0%, 16.4%, 9.7%, 14.0%, 31.0% and 48.3% in patients with PSA 4, 4.1-10; 10.1-20; 20.1-30; 30.1-40, and >40 ng/ml, respectively (p<0.0001). In patients with positive BS, the PSA levels were 20 and 10 ng/ml in 30.6% and 18.6% of the patients, respectively. CONCLUSION: According to our experience, there is a significant association between PSA plasma levels and the BS results in patients with recently diagnosed PA. However, a significant proportion of patients with bone metastasis have normal PSA levels, and therefore BS should be performed in all patients with recently diagnosed PA regardless of the PSA levels.

[Chronic prostatitis: diagnostic and therapeutic considerations].

Chronic prostatitis, whether of bacterial or non-bacterial origin, is a pathological entity commonly considered difficult to diagnose and to manage. In an attempt to provide a better understanding of the usefulness of Stamey-Meares fractional culture as a diagnostic test, the findings obtained with this technique in 34 patients, 5 with bacterial chronic prostatitis (BCP) and 29 with non-bacterial chronic prostatitis (NBCP) were analyzed. The multiresistance found in the antibiogram in 3 cases and the lack of correlation between these findings and the seminoculture, demonstrate that this technique should continue to be considered indispensable. Also, the value that should be appointed to the existence of organisms with non-proven pathogenicity is discussed. Some bases for a rational management are proposed and the various treatment alternatives, including the use of myorelaxants which in this series allowed to achieve resolution of the symptomatology in 59% cases are analyzed.

[Renal abscess in patients diagnosed with AIDS and disseminated tuberculosis].

Presentation of two cases of renal abscess formation in patients with stage IV C-1 AIDS and active associated tuberculosis. The microorganism isolated in the first case was S. aureus. Culture of the second cases was artefacted since antibiotic administration had already been started. Also, both patients showed abdominal abscesses, at spleen and liver level in the first case, and prostatic level in the second case, both compatible with Mycobacterium tuberculosis dissemination. Both cases showed a lethal evolution. The role played by the immunodeficiency as a precipitating agent in the extrapulmonary tuberculosis and in the formation of renal abscesses is analyzed.

Aberrant left pulmonary artery with tracheal stenosis without vascular sling.

We report a case of abnormal origin of the left pulmonary artery from the right pulmonary artery, associated with tracheal stenosis but with no vascular sling. This is the first such case, to our knowledge, without vascular sling.

Percutaneous nephrostomy in pyonephrosis.

A series of 76 pyonephrotic kidneys in 73 patients were drained by percutaneous nephrostomy (PN) tube and examined to evaluate the contribution of this technique to the treatment of pyonephrosis. In 71 patients, clinical symptoms disappeared 24-48 h after the procedure. Two patients died from sepsis subsequent to anuria and underlying malignancy. Once the acute phase had remitted, interventional procedures were carried out in 39 cases, and constituted the definitive therapy in 36. In 32 cases, elective surgery was the definitive therapy, including the 3 cases not resolved after interventional procedures. Three patients in whom the obstruction cleared spontaneously following PN needed no additional treatment. Major complications included 6 cases of sepsis, all of which resolved satisfactorily with proper medical therapy.

[Ureteral triplicity: trifid ureter with ipsilateral ureterocele and renal dysplasia in an adult with testicular seminoma].

Ureteral triplicity is a rare abnormality of which there are less than a hundred cases reported up to date. The possible absence of clinical signs can explain why this malformation passes unnoticed specially when there are blind branches and dysplastic renal segments. The paper presents the case of a 43 year-old male, attending the clinic on a testicle tumour consultation, in which in spite of the previously mentioned circumstances a preoperative diagnosis of trifid ureter with ipsilateral ureterocele and renal dysplasia was reached owing to the use of C.A.T.
