[Cryptosporidium sp. infection in Cuban individuals infected by HIV]. / Infección por Cryptosporidium sp. en individuos cubanos infectados por el VIH.

A study was conducted on the presence of Cryptosporidium sp in 47 Cuban adult patients infected by HIV in different infective stages in order to assess for the first time its prevalence in this group. The parasite was found in 18 patients (38.3%), of whom 18 (44.7%) were asymptomatic. The most frequent symptoms were aqueous diarrhea, fever, abdominal colics, asthemia and weight loss. Emphasis is placed on the frequently asymptomatic nature of these infections, which could be an important reservoir for nosocomial transmission of this disease among individuals with immunological disregulations.

[Hemolytic syndrome caused by primaquine and glucose-6-phosphate dehydrogenase deficiency]. / Síndrome hemolítico por primaquina y deficiencia de glucosa 6 fosfato deshidrogenasa.

A comparative study of 1,000 travellers coming back to Cuba from malaria-endemic areas is made. Screening for deficients of glucose 6-phosphate dehydrogenase by the methylene blue test is carried out in 500 of them; the other 500 did not undergo this test and were clinically observed throughout treatment. The figures for deficients and hemolytic syndrome were similar in the two groups. In addition the distribution according to skin color and chronology of case reporting in connection with the primaquine dose administered are analyzed. This test is useful as a screening technique in our country for prevention of hemolytic anemias through primaquine treatment.
