Endoscopy was undertaken to examine the gastroduodenal mucosa of 24 healthy dogs after seven days and again after 28 days of oral non-steroidal anti-inflammatory drug (NSAID) administration. The dogs were divided into four groups. One group received ketoprofen (1 mg/kg every 24 hours), one group carprofen (2 mg/kg every 12 hours for seven days followed by 2 mg/kg every 24 hours), a third group meloxicam suspension (0.2 mg/kg every 24 hours), and the last group gelatin (one capsule every 24 hours). Serum biochemical and complete blood count parameters did not change significantly after NSAID administration. Gastroduodenal lesions were observed in 17 dogs, but in all cases these were mild to moderate. The dogs receiving gelatin or carprofen showed the fewest and the least severe lesions, although there was no statistically significant difference between the three test drugs and the control group (P < or = 0.05). None of the dogs showed any clinical signs related to the gastrointestinal lesions.
The gastroduodenal mucosa of 30 healthy dogs was examined by endoscope after 7 days of oral non-steroidal anti-inflammatory drug administration. The dogs were divided into five groups. One group received ketoprofen (1 mg/kg every 24 h), one group copper-indomethacin (0.2 mg/kg every 12 h), one group 1 mg of prednisolone and 200 mg of cinchophen (1 tablet per 20 kg every 12 h), one group aspirin (15 mg/kg every 12 h) and one group gelatin (1 capsule every 12 h). Occult blood was not detected in the faeces either prior to or after non-steroidal anti-inflammatory drug administration. Packed cell volume, total plasma protein and buccal mucosal bleeding times did not significantly change after non-steroidal antiinflammatory drug administration. Gastroduodenal lesions were observed in 22 dogs. There was no significant difference in lesions between the ketoprofen, copper-indomethacin and prednisolone-cinchophen groups, but the gelatin group had significantly (p =0.05) fewer severe lesions and the aspirin group had significantly (p =0.05) more severe gastric lesions. The gastroduodenal lesions were mild and none of the dogs showed any clinically adverse effect.
A 40-year-old man who has sex with men (MSM) with urethral gonorrhoea failed to respond to treatment with 400 mg cefixime orally. Laboratory isolation of the post-treatment strain showed a minimum inhibitory concentration of ≥0.25 mg/L, which is a level of tolerance to cefixime that has not been previously documented in the UK. This case illustrates the importance of assessing all patients after treatment for gonorrhoea so that treatment failure and antibiotic resistance can be identified. It is vital that gonorrhoea culture continues to be attempted from all infected individuals to enable accurate diagnosis and antibiotic sensitivities. We also recommend that laboratories test for cefixime sensitivity routinely, given that it is one of the most commonly prescribed treatments for gonorrhoea.
The dosage of medetomidine and ketamine recommended in the literature for immobilising tigers produced severe cardiopulmonary depression in this animal. A reduced dosage of medetomidine and higher dosage of ketamine provided adequate restraint with decreased cardiopulmonary depression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
