[Giardiasis in clinical data].

The authors hospitalized and treated in 1990-1994 at their Clinic 127 patients where giardiasis was the main or secondary diagnosis. They wanted to draw attention to the increasing prevalence of the disease, to clinical manifestations and problems associated with treatment. Clinicians should consider the possible presence of this disease in different gastrointestinal manifestations, chronic hepatitis, hepatopathies as well as in acute IgM anti-HAV, HBsAg and HCV negative hepatitis.

[Ultrasonography of echinococcosis, toxocariasis and cysticercosis of the liver].

The diagnosis of tissue parasitoses has remained complicated until the present time for variability of clinical picture. Their incidence been increasing due to aimed and accidental findings of foci in parenchymal organs employing new methods of visualization such as computer tomography and especially ultrasonography whose advantage is a good detection rate, availability and a possibility to follow the dynamics of parasitosis development. The authors present a survey of ultra-sonographic findings of the liver in cases of tissue parasitoses occurring in Czechoslovakia, while using their own image documentation.

Evaluation of the resistance of Enterobacteriaceae strains to antibiotics--comparison of strains from clinical material versus environment.

The authors analyzed resistance to antibiotics of bacterial strains from the family of enterobacteriaceae comparing the resistance of two sets of strains, one set being strains isolated from clinical material of patients, the other being those isolated from municipal waste water of the 4th district of Bratislava. Referring to higher index of resistance in strains isolated from outer environment, they draw attention to high number of strains resistant to ampicillin and tetracyclin in clinical material and that of gentamicin-resistant ones from outer environment. Some views on standardization of empirical antibiotic therapy of infections due to strains from clinical material and outer environment are formulated and changes in the antibiotic spectrum effectivity as compared with past results as well as possible unsatisfactory success in treatment by means of currently applied broad spectrum antibiotics in cases of empiric therapy of infections are pointed to.
