Prognostic significance of prostate-specific antigen in endocrine treatment for prostatic carcinoma.

We have studied the prognostic significance of prostate-specific antigen (PSA), monitored monthly, in 24 patients with prostatic cancer (5 D1, 19 D2) on endocrine therapy. The pretreatment levels of PSA were high in all patients (mean value 41 ng/ml). It was found that PSA levels at the end of the first and sixth months of treatment were reliable prognostic indicators. At the first month evaluation PSA had decreased more than 50% from the initial values in the 16 patients with stable disease, while it had decreased less than 50% in those with progressing disease. At the end of 6 months, patients with stable disease had PSA levels within the normal range, while 8 of the patients who had progressing disease had levels higher than 10 ng/ml. Respectively 6 and 2 patients had also had increases in PSA levels at 3 and 6 months before scintigraphic demonstration of increased bone metastases.

[Sedation with flunitrazepam and its antagonism with flumazenil in endoscopic urological procedures: our clinical experience]. / Sedazione con flunitrazepam e suo antagonismo con flumazenil nelle procedure urologiche endoscopiche: nostra esperienza clinica.

Patients, especially males, do not easily stand endoscopic urological diagnostic examinations. So flunitrazepam (0.01 mg/kg IV) has been used to insure a suitable sedation. At the end of such examination flumazenil, a selective benzodiazepine antagonist has been injected. The levels of sedation and orientation so obtained and the cardiorespiratory parameters have been collected during a one hour follow-up from the intravenous injection of the antagonist. This method presents minimal side effects (a marginal, but statistically significative, systolic arterial pressure reduction), a completely normal coordination of movements and awareness of space and time relationship at the end of the observation period. Therefore it is a very good solution for short time examinations giving the chance to safely and shortly dismiss the patient.

[Nephrectomy in pulmonary tuberculosis patients: an anesthesiological approach]. / Nefrectomia in tubercolosi polmonare: un approccio anestesiologico.

Authors report a case of renal cell carcinoma in a patient suffering from cavitary tuberculosis. Nephrectomy was carried out in epidural anaesthesia together with Propofol continuous infusion and maintaining the patient in spontaneous breathing. The epidural anaesthesia avoided the possible pulmonary complications due to Nitrous Oxide and artificial ventilation. The combination of epidural anaesthesia with Propofol infusion gave both a better operability and a higher therapeutic compliance. The indications to this anaesthesiological method are analysed and discussed herein.

[Adjuvant chemotherapy]. / Chemioterapia adiuvante.

The authors treated 10 advanced renal cell carcinoma with circadian venous continuous infusion of 5-Fluoro 2-Deoxyuridine (FUDR). The drug was delivered by Medtronic Synchromed implantable pump in 14-day cycles alternating with 14-day intervals of physiologic saline infusion. Of the patient observed for at least 8 months (range: 8-32, median: 22.1) 1 showed progression. Circadian continuous central venous infusion of FUDR is minimally toxic. The FUDR can be delivered safely and conveniently in this way for long spans. This therapy is administrated in on entirely out patient setting, and associated with a normal quality of life.

[The non-depolarizing myorelaxants in orotracheal intubation. A clinical comparison]. / I miorilassanti non depolarizzanti nell'intubazione orotracheale. Confronto clinico.

The present study was designed to compare the rapidity of onset of neuromuscular blockade after administration of 5 different neuromuscular relaxants (succinylcholine, d-tubocurarine, pancuronium, atracurium and vecuronium) in 75 patients, randomly allocated in 5 treatment groups. The facilitation for endotracheal intubation was evaluated using a clinical score. The for onset relaxation was shorter when using succinylcholine. Among non-depolarizing relaxants an adequate facilitation for endotracheal intubation was observed, two minutes after administration of atracurium and vecuronium, while endotracheal intubation was difficult when using d-tubocuranine and pancuronium.
