[Ocular manifestations of myotonia atrophica].

In a 55-year-old male with a history of over 20 years of exposure to lead clinical, electromyographic and histological investigations demonstrated myotonic dystrophy. Cataract and high-grade concentric narrowing of the visual field were found bilaterally. The latter change has been reported sporadically in this disease.

[Course of cerebral cysticercosis].

In the light of 4 cases of cerebral cysticercosis observed in the period 1970-1976 in Zabrze the authors call attention to the possibility of a very long, lasting even tens of years, time period preceding development of intracranial hypertension and to the diagnostic difficulties in this period. If immunological reactions are negative and the cerebrospinal fluid is normal, presence of calcified cysts in skeletal muscles visible on radiograms may be helpful. An uncertain syndrome of cerebral manifestations in a patient with occupational exposure (butchers) requires ruling out of cysticercosis.
