Rickettsia helvetica in Dermacentor reticulatus ticks.

We report on the molecular evidence that Dermacentor reticulatus ticks in Croatia are infected with Rickettsia helvetica (10%) or Rickettsia slovaca (2%) or co-infected with both species (1%). These findings expand the knowledge of the geographic distribution of R. helvetica and D.

[Ocular manifestations of Lyme borreliosis in northwest Croatia].

Ocular manifestations in patients with Lyme borreliosis in northwest Croatia that occurred during the period between 1992 and 2001 were retrospectively analysed. The diagnosis of Lyme borreliosis was based on medical history, clinical manifestations, epidemiological data about tick contact, determinations of antibodies to Borrelia burgdorferi by serological assays, immunoblot analysis, therapeutic results and exclusion of other infectious agents of ocular disease. Of the eleven patients reported here with clinical manifestations of ocular Lyme borreliosis, 6 had chorioretinitis, 1 papillitis, 2 iridocyclitis, 1 occlusion of the arteriae centralis retinae, 1 neuritis retrobulbaris and 1 neuroretinitis.

[Leptospirosis and hemorrhagic fever with renal syndrome in northwestern Croatia].

Unlabelled: Leptospirosis is a worldwide spread zoonosis, therefore being also present in northwest Croatia. It has been recently discovered that hemorrhagic fever with renal syndrome (HFRS) is present throughout Croatia, not just in the previously well known epidemic foci. Because of the similar clinical presentation and epidemiology of the two diseases, it is important to know the exact etiology of the current disease.

Dual infection: tularemia and Lyme borreliosis acquired by single tick bite in northwest Croatia.

A case of dual infection, tularemia and Lyme borreliosis acquired by a single tick bite in northwest Croatia is presented. The patient came from a highly endemic region for Lyme borreliosis, where 45% of the ticks are infected with Borrelia burgdorferi. Clinically, tularemia manifested as the ulceroglandular form, and Lyme borreliosis manifested with arthritis (knee).

Apoptosis in human gastric polyps and adenocarcinomas: a stereological analysis.

Background/aim: The occurrence of apoptotic cells was analyzed in human normal gastric mucosa, polyps and adenocarcinomas.

Methodology: Histological classification was carried out on hematoxylin and eosin stained slides. The tissue was classified as follows: Normal gastric mucosa or adenomatous polyps.
