A urethrorectal fistula due to prostatic abscess associated with urolithiasis in a dog.

An 8-year-old, entire male crossbreed dog had a 2-day history of abdominal pain and straining to urinate and defecate. A diagnosis of urolithiasis with urinary retention, and probable prostatitis was made. The dog was treated with fluids and enrofloxacin. Five days later, ultrasonography of the prostate showed two hypoechoic areas compatible with abscesses. Twelve hours later, the patient started to urinate from the rectum during micturition and urethrorectal fistula was diagnosed. The omentalization of the prostatic abscesses and castration were performed and calculi were removed. The urethrorectal fistula was treated conservatively with an indwelling urinary catheter, a low residue diet and antibiotics. The dog recovered uneventfully without recurrence of the fistula.

Comparison of the analgesic effects of meloxicam and carprofen administered preoperatively to dogs undergoing orthopaedic surgery.

Thirty-two dogs undergoing operations to repair a torn cranial cruciate ligament or a fractured long bone were randomly allocated to one of two treatment groups in a study on postoperative pain. Sixteen of the dogs were given 4 mg/kg carprofen and the other 16 were given 0.2 mg/kg meloxicam subcutaneously before the operation. The signs of pain shown by the animals were assessed for 24 hours on a visual analogue scale, a discontinuous scoring system, and a score based on five behavioural and physiological variables. The dogs' heart and respiratory rates and their mean arterial blood pressures were also measured non-invasively at each assessment. Blood samples were taken before the surgery and 24 hours after it, and the concentrations of urea and creatinine were measured in plasma. Both drugs were effective in relieving the signs of pain for up to 24 hours in all the dogs. There were no significant changes in the concentrations of urea and creatinine, and no adverse effects were reported during the postoperative period.

Left perinephric abscess associated with nephrolithiasis and bladder calculi in a bitch.

An eight-year-old, entire female Pekingese cross, weighing 3.8 kg, had been inappetent with fever, depression, abdominal pain, vomiting and diarrhoea for seven days. The radiographic and ultrasonographic findings were consistent with glomerulonephritis, nephrolithiasis in both kidneys, bladder calculi and an accumulation of fluid in the left perinephric space. The clinical signs, together with the results of the diagnostic imaging, suggested that this fluid could be pus. A definitive diagnosis of a subcapsular abscess in the left kidney was established when this kidney was removed surgically. A histopathological examination of the kidney revealed a diffuse suppurative interstitial nephritis, membranous glomerulonephritis and an abscess invading the perinephric adipose tissue from the renal cortex. Twelve months after surgery the dog remains clinically stable, but owing to the disease of its remaining kidney its long-term prognosis is poor.

[Predictive risk factors for progression to cirrhosis in early stage alcoholic liver disease].

OBJECTIVE: To assess the risk factors of cirrhosis in early stage alcoholic liver disease. PATIENTS: We investigated 83 heavy drinkers (60 males and 23 females) in whom the first of two liver biopsies showed normal or pure alcoholic fatty liver. RESULTS: When the six following variables: sex, age, delay between the first and last biopsy, total duration of alcohol consumption before the first biopsy, daily alcohol consumption for the last 5 years before the first biopsy and the extent of fatty liver in the first biopsy, were considered together in stepwise regression analysis, the delay between the first and last biopsy (p < 0.0001), sex (P < 0.004) and the extent of fatty liver in the first biopsy (P < 0.06) significantly improved the prediction of cirrhosis. The odds ratio of cirrhosis for a women was 19.1 (confidence interval 95% [1.85-197]). The odds ratio for cirrhosis for a percentage of fatty liver > or = 5/10 was 7.4 (confidence interval 95% [1-92]). CONCLUSION: With the same delay between two liver biopsies, the female sex and the extent of fatty liver are two independent risk factors for the development of cirrhosis in heavy drinkers.

Infection risk and cost-effectiveness of commercial bags or glass bottles for total parenteral nutrition.

OBJECTIVE: To determine whether the greater daily expense of administering total parenteral nutrition (TPN) via plastic bags changed once daily, compared to glass bottles changed thrice daily, could be offset by savings from a reduction in nosocomial infections. DESIGN: The costs and potential benefits of commercially available TPN bags and TPN in glass containers were compared. Costs were computed from the viewpoint of the hospital, first in a general model and then for two specific examples, Crohn's disease and intensive-care unit (ICU) patients. The extra cost of using bags was $20 per day. The total cost of nosocomial bacteremia was estimated at $6,000. The monetary benefits of using TPN bags were $6,000XT, where XT was the percentage of nosocomial infections averted. We also considered that reduction in intravenous (IV)-line manipulation could reduce bacteremia-related mortality and computed a cost-per-life-saved ratio. RESULTS: Modeling showed that TPN in bags could yield a net benefit when the absolute reduction in the daily risk of nosocomial bacteremia reached the threshold value of 0.3%. Such a reduction could not be attained in patients with Crohn's disease, and corresponded to a 50% to 60% reduction of infection rates in ICU patients. Varying the risk of mortality attributable to IV-line-related infection from 1% to 13% resulted in a cost effectiveness of using TPN bags ranging from $90,000 to $7,000 per life saved in ICU, assuming a two-thirds reduction in IV-line infections, and from $180,000 to $14,000 if the infection rate was reduced by one third. CONCLUSION: The baseline cost-minimization analysis concluded that the extra cost of TPN bags was not justified by the extra savings. The cost-effectiveness analysis, however, found that the cost per life saved fell within the accepted range of public health interventions, provided a large fraction of infections are averted using TPN bags.

[Risks of severe digestive adverse effects of NSAIDs. Evaluation methods of mucoprotective drugs].

Frequency and severity of digestive adverse events due to NSAIDs are not similarly estimated by rheumatologists and gastroenterologists. A recent meta-analysis showed that NSAIDs users were at approximately three times greater relative risk for developing serious adverse gastrointestinal events than nonusers. Additional risk factors included age greater than 60 years, previous history of gastrointestinal events and concomitant corticosteroid use. Serious adverse gastrointestinal events are rare and preventive treatments cannot be evaluated with prospective trials. Therefore, the model of acute lesions induced by a 7 days treatment with NSAIDs is used. Most of patients given NSAIDs for a few days have gastric lesions (erosions or submucosal hemorrhage) which do not cause symptoms and spontaneously disappear despite the treatment continues. Evaluation of severity of lesions at day 7 after starting treatment proved to be adequate to compare gastrotoxicity of different NSAIDs and to assess efficiency of gastroprotection drugs. This model is appropriate to evaluate the protective effect of diacerheine.
