[Is prophyilaxis necessary after urodynamic tests? Our experience].

Urodynamic studies should be performed only on patients with sterile urine. The use of prophylaxis after urodynamic investigation is debated (positive urinoculture in 9 to 15% of cases). The Units of Urodynamics at the Urological Clinic of the University of Genoa and of the Galliera Hospital of Genoa assessed the prevalence of bacteriuria on a sample of 336 patients (314 females and 22 males), average age 62.3, between January and December 2006. All patients with sterile urine before examination underwent a complete urodynamic test. Concomitant diseases were: diabetes (7.7%), multiple sclerosis (3.5%), Parkinson's disease (1.2%), urinary retention treated by autocatheterism (1.2 %). Urinoculture was performed seven days after the urodynamic study. All patients were asymptomatic; 40/336 urinocultures were positive (E. coli 80%, Proteus M. 10%, other 10%). The prophylaxis does not eliminate but only reduces post-urodynamic infections; we believe that the cost-benefit ratio is unfavorable.

[Vesical sequelae of transverse myelitis. Long-term urodynamics observations in adult patients].

UNLABELLED: Transverse myelitis is a rare autoimmune inflammatory disease often secondary to viral infection of the spinal cord; it frequently has vesico-sphynteric complications. Between January 2000 and December 2005 we performed urodynamic examination on 13 consecutive patients (7 females and 6 males) with previous diagnosis of transverse myelitis. Mean age was 54.5 years; transverse myelitis had been diagnosed a mean of 6.3 years earlier; etiology of myelitis was viral infection in 5 cases, autoimmune in 3 cases, insect bite in 1 case, unknown in 4 cases. The neurological sequelae included paraparesis in 3 cases and tetraparesis in 2 cases. SYMPTOMS: dysuria 46%, slow stream 15%, pollakiuria 23%, urgency 30%; urge incontinence 38%, stress incontinence 15%. 3 patients performed 4 clean intermittent catheterisms (CIC), 2 patients 2 CICs. Eight patients had maximum cystometric capacity above 350 mL, the others had a mean capacity of 223 mL. Four patients showed no bladder sensitivity. Voluntary micturitional reflex was observed in 4 patients. Detrusor overactivity was diagnosed in 9 patients, 10 patients had mean residual post-micturition (RPM) of 218 mL, 2 patients showed detrusor-sphincter dyssynergia, 2 patients were found to be obstructed at pressure-flow study. Urodynamic follow-up is indicated in these patients with or without neurological complications (possibility of detrusor overactivity, urinary retention, detrusor-sphincter dyssynergia); the follow-up personalizes the diagnosis and therapy, and prevents complications.

Hyperbaric oxygen therapy in the treatment of Fournier's disease in 11 male patients.

PURPOSE: Optimal tissue oxygenation, as obtained by hyperbaric oxygen therapy, potentiates or restores the host's bactericidal mechanisms and wound healing activity in patients afflicted by serious synergeic aerobic and anaerobic infections of the cutaneous and subcutaneous tissues. Furthermore, hyperbaric oxygen therapy has a direct toxic effect on anaerobic bacteria. We describe our experience with hyperbaric oxygen therapy in the treatment of 11 patients with Fournier's syndrome. MATERIALS AND METHODS: The average age of our patients was 59.5 years; the most common predisponsing condition was diabetes. All patients were treated with antibiotic therapy and hyperbaric oxygen therapy (minimum 5 and maximum 24 cycles, consisting of 90 minutes 2.5 atmosphere absolute pressure). Furthermore, 6 of these patients underwent surgical débridement of the wounds and 3 patients underwent delayed reconstructive surgery. RESULTS: The results we obtained with hyperbaric oxygen therapy as an adjunctive measure for the treatment of these infections were excellent; our mortality rate for Fournier's disease was 0. Moreover, no complications whatsoever were observed. Furthermore, the 3 patients who underwent delayed corrective surgery presented with well healed tissues and their operations were not complicated by infections or other pathological conditions. CONCLUSIONS: We believe that our findings, although limited in number, underline the excellent results that can be obtained with hyperbaric oxygen therapy as an adjunct treatment in Fournier's disease.

Acetaldehyde-induced impairment of protein glycosylation in liver Golgi apparatus.

The effects of acute ethanol intoxication on the glycoprotein metabolism of rat liver Golgi apparatus have been investigated. A marked reduction of the galactosyltransferase and sialyltransferase activities was observed in Golgi membranes 6 h after ethanol administration (6g/Kg body wt) together with the retention of glycoproteins in the hepatocyte. Methylpyrazole, an inhibitor of alcohol dehydrogenase, administrated "in vivo" (10 mg/Kg body wt) prevented the ethanol-induced inhibition of both the transferase activities. Acetaldehyde formed "in vitro" unstable and stable adducts with Golgi membrane proteins and with purified galactosyltransferase. These results suggest that the impairment of glycoprotein metabolism at the level of liver Golgi apparatus may be mediated, at least in part, through the acetaldehyde formation during ethanol oxidation.

Treatment of urinary tract infections with ciprofloxacin.

Urinary tract infections in 32 patients were treated with 250 mg of ciprofloxacin twice daily for seven to eight days. Clinical and laboratory examinations were performed before and after treatment. The infections were eradicated in 30 of the 32 patients. Ciprofloxacin was well tolerated by all patients.

Successful extraction of renal cell carcinoma thrombus extending into the right atrium using extracorporeal circulation, profound hypothermia and cardiac arrest.

The authors report a case of successful extraction of renal cell carcinoma thrombus extending into the inferior vena cava and right atrium in a 36-year-old female patient using extracorporeal circulation, profound hypothermia and cardiac arrest.
