Pedal polydactyly: an overview with case report.

Polydactyly is a fairly common congenital condition of the foot, and is characterized by supernumerary digits and/or metatarsals. It may be an isolated condition or part of a congenital syndrome. Polydactyly is generally classified into three major groups: medial ray (preaxial), central ray, and lateral ray (postaxial). A review of polydactyly and an unusual case report of central ray involvement and its surgical correction are presented.

[Verification of the usefulness of Estrophan inj. Spofa in the control of reproductive parameters in sows after weaning of piglets].

Cloprostenol, a prostaglandin F2-alpha analogue, used in the Czechoslovak preparation Oestrophan ing. Spofa was tested by a new nontraditional use. The effect of cloprostenol use on reproductive parameters of sows after piglet weaning was followed in a set of 456 experimental and 434 control sows. The effect of single intramuscular instillation of cloprostenol was tested in five partial observations: to multiparous sows at a dose of 175 micrograms on the day of weaning (experimental group no. 1), on day 1 after weaning (group no. 2), 500 micrograms on day 1 after weaning (group no.3), to primiparous sows at a dose of 500 microgram on day 1 after weaning (group no. 4). The treatment used in group no. 4 was also applied to 42 primiparous sows kept on a farm with regular occurrence of post-weaning anoestria of sows (experimental group no. 5). These parameters were evaluated: dynamics of oestrus onset within five, and/or ten, days after weaning, average length of the weaning--first insemination interval, conception rate after the first insemination in dependence on terminated deliveries and parameters of piglet litter. Cloprostenol application did not have a statistically significant effect on the evaluated reproductive parameters. The percentage of multiparous, and/or primiparous, sows in which the oestrus onset was not detected by the 10th day after weaning, did not show any large differences in the various experimental and control groups (17.09 vs. 16.55%, 23.53 vs. 32.56%, 13.66 vs. 18.13%, 29.54 vs. 30.30%; P > 0.05). On the farm with regular occurrence of post-weaning anoestria there were 73.81% of primiparous sows with oestrus onset after cloprostenol instillation and 71.43% primiparous sows without treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Painless myocardial ischemia and atherosclerous valvulopathies--their great statistical prevalence.

3384 patients over 40 years old referred to our Cardiovascular Laboratory for overt cardiovascular complaints were examined by usual non-invasive investigations. Painless myocardial ischemia (PMI) prevalence was 17.49% and degenerative aortic and mitral valvulopathies incidence was 15.60%. PMI predominate in women especially in the group 50-59 years of age in which painful forms of ischemic heart disease have the highest prevalence in men. Although more affected by painless myocardial ischemia, women show a more favourable outcome than men. Ischemic heart disease was frequently associated with isolated mitral regurgitation. In the elderly patients mitral valvulopathy was associated with calcific aortic stenosis. No significant difference was noted between mitral and aortic valvulopathies prevalence.
