Experimental echinococcus infection in the mouse model: pericystic cellular immunity reaction and effects on the lymphoid organs of immunocompetent and thymectomized mice.

Echinococcus can infect man as an accidental intermediate host causing hydatid disease. The infection persists and the growth of the cysts advances, while the patient usually remains asymptomatic for years. Experimental Echinococcus infection in mice provides a well described model for the study of the parasite-host relationship that permits the evolution of the disease despite the activation of the host's immune system.

A simple enzyme immunoassay for detecting brucellosis antibodies.

A simple enzyme immunoassay was developed and evaluated for serological diagnosis of brucellosis in 25 patients with various forms of brucellosis and 292 control patients with other conditions and disorders. All brucellosis patients gave a positive test with the initial sample. In 3 acute, febrile brucellosis patients with follow-up sera taken during therapy a sharp drop in specific antibody was noted.

Short-term versus prolonged systemic antibiotic prophylaxis in patients treated with indwelling catheters.

Newly hospitalized patients with stroke treated by indwelling catheters were assigned randomly to 3 treatment groups. Group 1 (24 patients) received 3 gm. ampicillin intramuscularly in divided doses 1 hour before, at the time of and 6 hours after insertion of the catheter.

Statistical aspects of hydatid disease in Greek adults.

A retrospective study was undertaken to estimate the incidence of hydatidosis among Greeks over 18 years of age. Discharge and operating room records in all community and private hospitals during the period 1 January 1969 to 31 December 1975 were reviewed, and new hydatid patients were registered. Hydatid disease was diagnosed in 4,202 adults.

[Fasciolar hepatic abscesses: value of hepatic ultrasonography. Apropos of 3 cases].

Hepatic abscess is a rare complication of fasciolasis. The ultrasonographic appearances of these abscesses are not well known. The finding of nodular echodense images in the hepatic parenchyma may cause diagnostic confusion.

Hydatid disease in asymptomatic young carriers in northern Greece.

An epidemiological survey to determine the prevalence of echinococcosis in children and adolescents was made in Grevena County of northern Greece. Counterimmunoelectrophoresis was used to screen 2,736 school children whose ages ranged from 6-18 years; among them, three asymptomatic carriers were identified. The diagnosis was subsequently confirmed by liver radioisotope scanning.

Clinical evaluation of cefotiam (CGP/14221) versus cephalothin in the treatment of urinary tract infections.

A study was carried out in 35 patients with urinary tract infections to compare the efficacy and tolerance of cefotiam and cephalothin. Patients received at random either 1 g cefotiam twice daily (19 patients) or 1 g cephalothin 4-times daily (16 patients) parenterally over a period of 10 days. Therapeutic efficacy was assessed mainly on disappearance of bacteriuria.

Comparative in vitro activity of netilmicin, amikacin, tobramycin and sisomicin against gentamicin highly-resistant enterobacteriaceae.

Netilmicin was compared with sisomicin, tobramycin and amikacin against 65 recent clinical enterobacterial isolates found to be highly resistant to gentamicin (MIC larger than or equal to 80 microgram/ml). Netilmicin showed a high activity against 20 out of 65 strains tested. Most of the sensitive strains (60%) to netilmicin required a concentration of gentamicin equal or lower than 160 microgram/ml for inhibition.
