Severe thrombocytopenia associated with acute folic acid deficiency in two inpatients is described. Both patients had severe hemorrhagic manifestations. A similar syndrome has previously been described in patients who have undergone extensive surgery or dialysis or both. The present cases show that acute folic acid deficiency can occur in other circumstances and may go unrecognized because other signs in the peripheral blood of a megaloblastic process may be minimal. A good response was obtained with folic acid therapy.
A case of therapy-related leukemia is described. Other cases of acute nonlymphocytic leukemia have been associated with the intramuscular administration of thiotepa (an alkylating agent), but this patient received only intravesical instillations of the drug. The interval between the start of chemotherapy and the onset of leukemia was 56 months.
A case of septicaemia due to Neisseria catarrhalis occurring in an immunosuppressed individual is described. The clinical syndrome closely resembled that of N. meningitidis septicaemia. The potential pathogenicity in the immunosuppressed patient, of organisms usually considered harmless is stressed.
