the new diphtheria-tetanus-acellular pertussis-hepatitis B virus-inactivated polio/ Haemophilus influenzae b vaccine administered at 3, 5 and 11 months of age was safe and at least as immunogenic as the comparator vaccines thus providing an effective and more comfortable option for this infant vaccination schedule.

This study analyzed the approximate cost of treatment of patients hospitalized with a diagnosis of imported malaria in Slovakia. Between 2003 and 2007, 15 patients with imported malaria were hospitalized. The mean direct cost of the treatment was 970.75 euros and the mean indirect cost was 53.15 euros. For the patient with the highest cost of treatment, the use of mefloquine prophylaxis would have represented only 0.5% of the total direct cost of treating the disease. Despite the partial resistance of plasmodia, malaria chemoprophylaxis is unequivocally a cheaper choice than subsequent treatment of malaria.Key-words: Imported malaria. Direct costs. Indirect costs. Slovak Republic. ReSuMoAnálise do custo aproximado do tratamento dos doentes hospitalizados na Eslováquia com malária importada. Entre 2003 a 2007, foram internados 15 doentes com malária importada. Os custos médios diretos do tratamento foram avaliados em 920,75 euros e indireto em 53,15 euros. No doente com o custo mais elevado de tratamento, a utilização da profilaxia com mefloquina representaria somente 0,5% do total dos custos diretos do tratamento da doença. Apesar da resistência parcial do plasmódio, a quimioprofilaxia da malária é inequivocamente uma opção mais econômica do que o tratamento posterior da malária.

The objective of this study was to examine plasma homocysteine levels and C677T methylenetetrahydrofolate reductase (MTHFR) gene polymorphism in two ethnic groups from Slovakia. The samples consisted of general Slovak-Romany population (68 men and 81 women) from Southwestern Slovakia and the Slovak-Caucasians (174 men and 177 women) who participated in the CINDI project. The homocysteine levels were examined by HPLC, the analysis of MTHFR genotypes was done by PCR. The Slovak-Romany men (12.0±5.6 (S.D.) μmol/l) and women (9.2±2.6 μmol/l) have significantly lower plasma homocysteine levels (p<0.024 and p<0.00001) when compared to Caucasians (13.3±5.1 μmol/l in men and 11.3±4.3 μmol/l in women). The genetic equilibrium is assumed for the gene frequencies of the MTHFR polymorphism in both samples. The distribution of MTHFR genotypes did not differ between the two populations (TT 13 vs. 10.6 %; CT 46.6 vs. 41.7 %; CC 40.4 vs. 47.7%, zeta2 = 2.315, df=2, ns). The effect of MTHFR genotypes on homocysteine levels was not confirmed in the Slovak-Romanies and TT homozygosity significantly increased plasma homocysteine levels only in Slovak-Caucasians (11.5±4.4 mmol/l, ns; vs. 14.8±4.8 mmol/l, p<0.002, respectively). To our knowledge, this is the first epidemiological study in the Romany population examining distribution of the MTHFR genotypes and their effect on homocysteine levels. Further studies are needed to establish the variety of cardiovascular risk factors among Romanies in order to evaluate the significance of particular factors.
