    ABSTRACT: Dirofilariosis is a vector-borne disease that is spreading in Europe from the southern endemic regions to the northern countries, including Slovakia. The dog parasites Dirofilaria immitis and D. repens are zoonotic agents, responsible for the development of human pulmonary and subcutaneous dirofilariosis, respectively. The present paper reports the third case of human dirofilariosis in Slovakia caused by D. repens. The pacient, a 41-year-old woman, was referred with tumour process in the subcutaneous area of the right forearm. Within 14 days the USG confirmed the rapid increase of the nodule from 20 × 10 mm to 30 × 25 mm. The surgical extirpation of the tumour was indicated. Histological examination revealed the formation with eosinofilic rime and the presence of a worm in the centre, detected as D. repens. Keywordshuman dirofilariosis– Dirofilaria repens –Slovakia

    ABSTRACT: We report the case of a 4-year-old boy suffering from a cerebral form of toxocariasis. High serum titres of anti-Toxocara antibodies indicated that the primary infection was induced by a high number of Toxocara eggs and that the larvae did not penetrate to cerebrospinal fluid due to the hematoencephalic barrier. MRI of the patient’s brain showed multiple focal lesions spread diffusely in almost all parts of the brain, predominantly paraventricularly. These might be eosinophil-rich granulomatous infiltrates enclosing larvae. Extensive morphological changes were the cause of serious neurological symptoms, most of them being reversible after follow-up therapy. Radiology proved to be useful diagnostic method, but the specific serological assessment had a key role for the final diagnosis. In conclusion, diagnosis of this patient was intracranial primary Toxocara infection with central quadruparesis and parainfective myocarditis.

    ABSTRACT: Alveolar echinococcosis (AE), caused by proliferating metacestodes of the parasitic fox tapeworm Echinococcus multilocularis, is a life-threatening disease in humans. In this study we report four human cases of AE in Slovak Republic with regard to various clinical manifestations and susceptibility to chemotherapy with albendazole or mebendazole. Patients were monitored serologically by ELISA test and Western Blots within 2–5 years after initiation of chemotherapy/surgery. Using computerized tomography (CT) we compared morphological changes of the parasitic lesions in the liver during the course of treatment. The parasitic lesions in the CT were manifested as nodular hyperplasia with hyper or hypodense zones and calcified foci within the lesion. In other cases the lesion was visualised as a hypodense poorly-delineated septated focus without calcifications. In the last case, the diagnosis of AE was confirmed only at surgery. Calcified foci found inside the main parasitic lesions were the only abnormality that was detected in two cases and were absent in other two cases. The levels of specific anti-parasitic antibodies followed the pathomorphological changes in the livers. Total IgG levels to Em2+ and EmP antigen declined gradually during the follow-up (1–5 years) and disappeared only in the patient receiving radical surgery (cured). In comparison with total IgG, concentration of the IgG4 antibody subclass seemed to correlate more adequately with the outcome of therapy as their levels decreased in improved/stabilised patients, but were elevated in “aggravated” patients. We showed that, in patients with AE in Slovakia, radical surgery of parasitic foci proved to be the most successful treatment and, in inoperable cases, albendazole and mebendazole were differently effective. Moreover. IgG4 levels rather than total IgG to protoscoleces antigens proved to be more sensitive serological marker of the progress of therapy.

    ABSTRACT: The paper presents three case reports of toxocarosis in children - two siblings and their cousin - with probable common source of infection. Toxocariasis was diagnosed by serology based on the finding of eosinophilia (70%) during examination for anemia in one child and by a purposeful preventive screening (depistage) examination in the two other children. Two siblings displayed numerous hypoechogenic foci of the size up to 1 cm in ultrasonographic examination while the echogenicity of the liver was diffusely increased. Laboratory examination revealed elevation of aspartate aminotransferase in two of them. All three children were treated with mebendazol under the control of blood picture, hepatic tests, USG and antibodies against the toxocariasis antigen.

    ABSTRACT: The authors investigated 130 patients with herpes zoster. They confirmed its more frequent incidence in patients above the age of 60 years. The most frequent site (34.6%) was the innervation area of thoracic nerves and the area of the trigeminal nerve (27.7%). They recorded 24.6% complications associated directly with herpes zoster. Ramsay-Hunt's syndrome was recorded in three subjects. They did not observe neuralgias in child patients and in patients with malignant tumours. During hospitalization they administered to 128 (98.5%) patients acyclovir by the i.v. route, to 27.3% longer than 5 days, with a favourable therapeutic effect, without undesirable side-effects.
