Diagnostic value of cytokine assays in cerebrospinal fluid in culture-negative, polymerase chain reaction-positive bacterial meningitis.

Analysis of bacterial DNA using a polymerase chain reaction performed with broad-range eubacterial 16S rDNA primers may yield a diagnosis of bacterial meningitis in cases where Gram staining of cerebrospinal fluid (CFS), antigen detection techniques or culture fail. Since this PCR technique occasionally gives false-positive results due to contamination of samples or laboratory reagents, a study was performed to establish the diagnostic value of assaying concentrations of tumour necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) in 90 CSF samples. A high correlation was found between a positive PCR result and the concentrations of TNF-alpha and IL-10, indicating that cytokine assays may be used as a confirmatory test. The findings suggested that a combination of the PCR technique, amplicon sequencing and assay of TNF-alpha and IL-10 concentrations in CSF is a reliable and cost-effective procedure for diagnosis of culture-negative bacterial meningitis.

Correction of stress urinary incontinence: laparoscopy combined with vaginal suturing.

The authors review the published techniques of laparoscopic colposuspension combined with vaginal suturing. Particular emphasis is given to their own technique, first published in 1992, and to that of Harewood (1993), which is similar. Both involve a Burch-like colposuspension using a technique similar to that of Gittes and Loughlin. This is possible looking inside the pelvis through a laparoscope and using a handle-needle. Published results are similar (about 70% success rate), but the authors point out that the Breda technique is simpler, cheaper, and less time consuming (only one trocar instead of three) and has had a longer follow-up (up to 3 years instead of 19 months). The authors review many other similar techniques reported between 1993 and 1995 with good results but based on rather limited experience. The conclusion is that the laparoscopic technique with vaginal suturing seems a promising way to approach stress urinary incontinence in the female patient.

[Laparoscopic surgery of stress urinary incontinence in women].

The Authors carried out a literature review on stress urinary incontinence (SUI) treatment using laparoscopy or pelvioscopy. They report their experiences in using a pubo-vaginal percutaneous colposuspension assisted by pelvioscopy. Of 22 treated patients, there was a total correction of the incontinence in 15 patients. (68.12%) with a median follow-up of 18.6 months. They report also their first experience with the Retzius plasty of Manhes by laparoscopy (3/4 patients treated are continent, 1/4 has recurrent SUI during times of stress). They conclude that laparoscopy and pelvioscopy treatment can be valid alternatives to traditional surgery if made on selected patients.

Stage A1 prostate cancer: follow-up with digital rectal exploration, prostate markers, fine-needle aspiration, ultrasonographically guided needle biopsy and biopsies of the residual prostate with resectoscope.

From January 1985 to December 1990, we performed 921 TURP and 23 retropubic adenomectomies. In 70 patients (7.4%) histological examination revealed an incidental carcinoma of the prostate (stage A), 51 of which (72.8%) were A1 and 19 (27.2%) stage A2. In our classification A1 covers cases with < 3 G1 focal lesions [Boxer, 1977]. Thirteen of the A2 cases underwent radical prostatectomy: 1 pT1G1-2, 9 pT2G1-2, 3 pT3G2 (TNM 1978); the remaining 6 were given palliative treatment. The 51 stage A1 patients were recalled for follow-up evaluation, only 20 came for checking. They were reassessed by means of DRE, markers, prostate cytologic aspiration, echo-guided transperineal needle biopsy and resection of the prostatic cavity. Our experience seems to suggest that, if we define A1 as < 3 G1 chips or less, this stage is to be considered an incidental illness that seems not to require further treatment, but only a policy of surveillance with yearly markers, DRE and echo-guided needle biopsy.

Laparoscopic nephrectomy with vaginal delivery of the intact kidney.

The first case of laparoscopic nephrectomy in Italy is described. The patient was a 51-year-old woman with a small, nonfunctional, tuberculous left kidney. The organ, once detached from its lumbar site, was brought in to the pelvic cavity and extracted from the body via a posterior colpotomy. In this way, the integrity of the organ is preserved, hence, this could be the preferable route when dealing with a little kidney tumor in a woman.

Treatment of hydrocele: randomised prospective study of simple aspiration and sclerotherapy with tetracycline.

Following reports in the literature on the efficacy of tetracycline sclerotherapy in the treatment of hydroceles, we carried out a randomised prospective study of 45 patients (50 hydroceles), comparing simple evacuation with tetracycline sclerotherapy. The results revealed no statistically significant difference in the percentage of success between the 2 groups, but complications were more common in the patients treated with tetracycline. The good results reported by other authors in non-randomised studies are, therefore, not confirmed.

Nomogram for penile biothesiometry.

Three hundred and fifty men, aged between 17 and 80 years, with normal sexual anamnesis and without any neurological pathology, underwent finger (index) and penile biothesiometry using a biothesiometer. Tabular and graphical nomograms were obtained according to age and instrumental values. The use of the above-mentioned nomograms is an effective aid in detecting each individual case.

[Cost-benefit relationship between endoscopic resection (TURP) and open surgery (Millen) in prostatic hypertrophy ].

Evaluation of the cost/benefit relationship between TURP (50 cases) and Millin (30 cases). The factors considered are as follows: average post-operative hospitalization, average catheterisation time, average operation time, cost of materials, number of operators employed, number of transfused blood units. The post-operative hospitalization relating to the two kinds of operation varies considerably with a difference of 5.15 days less for the TURP, while the average catheterisation time doesn't seem to be affected. Blood transfusion was necessary in the 43.3% (0.75 unit/patient) of cases for the Millin compared to the 14% (0.26 unit/patient) for the TURP. Evaluation of economical advantages between TURP and Millin shows a relationship of 1:2.3 in favour for of TURP.

[Epididymitis in adults. Retrospective study of 110 cases].

A review was conducted of 110 cases of epididymitis, most of these patients (71.9%), especially those under 50 years of age, having negative urine cultures: this appears to confirm the high frequency of Chlamydia T infection in the age group 20 to 50 years when sexual activity is at its maximum. Urinary output was normal in 60 of 79 patients and urography exploration provided normal results in 69 of the 110 patients (63%), particularly in those under 50. It is concluded, therefore, that urography is not necessary in patients under 50 but remains necessary in those in older age groups.
