Home total parenteral nutrition in a "no-bowel" patient in Spain.

OBJECTIVE: To report a case of a patient with no functional bowel who was receiving home total parenteral nutrition in a country that has had a few professional experiences in this area of therapy. CASE SUMMARY: A woman with a history of scattered colonic polyposis developed a mesenteric tumor that caused intestinal obstruction. Tumor withdrawal required the excision of 1.5 m of jejunum-ileum. Postoperative complications required further surgical intervention and subtotal intestinal resection. Duodenocolic anastomosis was not possible and a high output and permanent fistula remained. DISCUSSION: The complications of home parenteral nutrition addressed in the literature are reviewed. The problems encountered in our patient have been resolved. CONCLUSIONS: After three years of postoperative survival, we believe the quality of life of our patient has increased and the parenteral nutrition team members are much better prepared to manage patients with similar problems.

The pharmacological profile of aceclofenac, a new nonsteroidal antiinflammatory and analgesic drug.

Aceclofenac is a new phenylacetic acid derivative provided with marked antiinflammatory, antiarthritic, analgesic and antipyretic activities in animal experimental models. While maintaining its potency Aceclofenac demonstrates better gastric tolerance and consequently offers greater potential security than other highly active agents such as Indomethacin and Diclofenac.

Pharmacology of the potent new non-steroidal anti-inflammatory agent aceclofenac.

Aceclofenac (2-[(2,6-dichlorophenyl) amine]phenylacetoxyacetic acid; CAS 89796-99-6) is a new orally effective non-steroidal anti-inflammatory agent of the phenylacetic acid group which showed remarkable anti-inflammatory, analgesic, and antipyretic properties. Hence, aceclofenac possesses a potent inhibitory activity in several models of acute and chronic inflammation in rodents, and resembles indometacin and diclofenac in its pharmacodynamic profile, being superior to naproxen and phenylbutazone. In addition, aceclofenac was found to be highly active against sodium urate-induced synovitis in dogs and adjuvant-induced polyarthritis in rats, both prophylactically and therapeutically. The analgesic effect of aceclofenac on the pain elicited by chemical and mechanical stimuli was nearly equal to or slightly better than that of indometacin and diclofenac. Fever induced by brewer's yeast injection in rats was also markedly suppressed by aceclofenac. In contrast, the acute gastric ulcerogenic activity of aceclofenac was about 2, 4 and 7-fold lesser than that of naproxen, diclofenac, or indometacin, respectively. As a consequence of its high anti-inflammatory activity and lower potential for gastric damage aceclofenac exhibited the most favourable therapeutic ratio in comparison with indometacin, diclofenac, naproxen, and phenylbutazone. These data indicate that aceclofenac could be a potent anti-inflammatory and analgesic agent with a wide margin of safety in clinical practice.

Pharmaco-toxicological effects of acetaminophen in rodents. Battery of tests to screen potential analgesic acetaminophen derivatives.

The pharmacological effects of acute oral administration of acetaminophen have been extensively evaluated in rodents. Using this drug as reference compound we have also standardized several pharmaco-toxociological tests in order to select new analgesic-antipyretic acetaminophen derivatives. According to the results obtained in this work, the following battery of assays is proposed to screen these compounds: a) pharmacological: antipyretic activity against Brewer's yeast-induced pyresis in rats; analgesic activity against chemical-induced writhings in mice and paw pressure test in rats; b) toxicological: oral acute toxicity in mice with and without phenobarbital pretreatment; determination of SGOT and SGPT activities as well as total bilirubin in mice. The usefulness of this procedure in the evaluation of drug effects is also considered.
