On reviewing our cases of hydatid disease seen over a period of 20 years (1978-1998), we encountered a number of unusual radiological appearances and sites, which are demonstrated in this pictorial review. We briefly discuss the pathology of hydatid disease and its complications.
Ketamine HCl [2-(o-chlorophenyl)-2-(methylamino) cyclohexanone HCl] concentrations in whole blood were used to study the pharmacokinetics of i.v., i.m., and rectal administrations, at a dose of 25 mg/kg, in normal domestic cats. Absorption was rapid with both the i.m. and rectal routes. Systemic availability was 51% (SEM 10) for the i.m. dose and 43.5% (SEM 6.1) for the rectal dose. The first-pass effect had a minimal influence on the metabolism of ketamine HCl administered rectally. The elimination rate constant (beta) of the drug was statistically similar in the i.v., i.m., and rectal groups, at a 95% level of significance (P less than 0.05). At the dosage rates studied, ketamine HCl produced an anesthetic effect in the cat following i.v., i.m. and rectal administration.
SummaryThis communication records our experience with the percutaneous catheter drainage (PCD) of 22 amoebic liver abscesses in 19 patients who had failed to respond to amoebicidal therapy. In one patient with a left lobe abscess, imminent rupture was an additional indication for drainage. PCD combined with amoebicidal therapy not only expedited recovery, but was curative in all 19 patients. There were no complications. We conclude that PCD is a most useful adjunct to drug therapy and recommend its routine use in the management of drug-resistant amoebic liver abscesses.keywords amoebic liver abscess, drug resistance, catheter drainage, Kuwait correspondence R.

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.
