An acute myocardial infarction was observed in a 62-year-old patient with hemophilia A, as well as myxedema, hypertension, obesity, hypercholesterolemia and angina pectoris. The occurrence of myocardial infarction in hemophiliacs is rare, and, to the best of our knowledge, this patient represents the fourth documented case in the literature.
A patient had an acute attack of intermittent porphyria with severe neurologic manifestations, hypertension, and tachycardia. Treatment with propranolol hydrochloride (Deralin [Israel]; Inderal, comparable US product) intravenously administered in a total dose of 284 mg during a period of 18 hours, was followed by clinical remission associated with a decline in urinary excretion of porphyrin precursors.

Serum immunoglobulin levels were examined in a group of twelve healthy adults who underwent accidental splenectomy. Depressed mean IgM levels and elevated mean IgA levels were found in these patients as compared with the control group consisting of forty-five healthy, untraumatized volunteers. Immunoglobulin changes may have some relevance for the increased tendency to severe infections which has been noted after splenectomy.
A patient with chronic myelocytic leukemia in whom a clinical and hematological remission occurred after a single course of busulfan is described. The remission lasted for a period of 13 years and during that lapse of time, she gave birth to a healthy child. Afterwards, acute myeloblastic leukemia was diagnosed. Following treatment with rubidomycin and arabinoside C another remission was achieved, lasting already for 18 months.

Peripheral blood lymphocytes from a patient with T cell chronic lymphocytic leukemia were examined by a combination of cell markers (E and M rosettes, and surface Ig), the graft-vs.-host reaction, thymic humoral factor (THF) and scanning electron microscopy. It was not possible, at first, to determine by conventional methods whether the leukemic cells were of the B or T type, but the THF and graft-vs.-host reaction showed that T cell precursors were present. These cells were incompetent immature T cells that underwent maturation following treatment with THF. Three months later, the T cell nature of the disease was clearly demonstrated by the E rosette technique, although at this time the cells were no longer influenced by THF.

An elderly patient with chronic myelomonocytic leukaemia developed severe bone pains and acute gonarthritis. Intravenously administered cytosine arabinoside brought dramatic relief of the bone pains and led to a rapid subsidence of the arthritis, without achieving haematological remission.
