Neocarzinostatin (NCZ), an acidic polypeptide antibiotic, was given to 47 patients with cancer and leukemia, and tolerance to two schedules, a single dose given as a 2 hour infusion and a continuous infusion over 5 days was investigated. Immediate reactions, including fever, chills, rigor, hypertension and mental confusion, were dose-limiting for the 2 hour infusion schedule, occurring at 3000 U/m2 and higher. Continuous administration for 5 days eliminated the immediate reactions and then hematological toxicity--often prolonged leukopenia and thrombocytopenia--became dose-limiting. Other toxicities of NCZ at both dose schedules included anemia, fever and chills, anorexia, nausea and vomiting, hepatic dysfunction, azotemia, hypophosphatemia, aminoaciduria, stomatitis, phlebitis and/or cellulitis at the venous infusion site and pruritus. Patients with solid tumors who had received little or no prior chemotherapy and had good bone marrow reserve tolerated up to 6000 U/m2/24 hours X 5 days. One patient with previously treated acute myelocytic leukemia was induced into a good partial remission lasting 10 weeks.

A study of 3451 cholesterol determinations in different diseases was carried out. The mean cholesterol levels for male and female adults and children with different diseases were compared with values for their healthy counterparts. Sickle cell anemia, leukemia, liver cirrhosis, hepatosplenomegaly, tuberculosis, and diabetic, nutritional, ataxic, and tropical neuropathies in male and female adults were associated with reduced cholesterol level while in children malnutrition and anemia were the main causes of low cholesterol levels. Obesity and hypertension caused an elevated level but the mean values were within the range for adult Nigerians in the high income group. Only nephrotic syndrome in both adult and children was associated with a markedly increased cholesterol level in Nigerians of low income status.

The data of 140 patients with polycythemia vera during the period 1955--1975 were analyzed with regard to clinical signs and prognosis. The average age was 53,4 years. The sex ratio was 1.9:1 in favor of men. The most frequent symptoms were headache and vertigo. In more than half of the cases hepatosplenomegaly and hypertension were found. Besides typical changes in the blood count with elevated erythrocytes, hemoglobin, hematocrit, leukocytes and thrombocytes, increased levels of alkaline leukocyte phosphatase and uric acid were found. As to therapy, after 32P-medication the survival was two years longer than after phlebotomy. In 9 patients osteomyelofibrosis developed, and in 7 cases chronic myeloic leukemia. The mean age of death was 61 years.

Conclusions drawn from the post-mortem examination of 226 subjects who died of cerebral haemorrhage are presented. There were slightly more women than men (53%) in the series. Arterial hypertension (68%) was the main cause of death, while renal disease, leukaemia, angioma of the pons, and embolism due to bacterial endocarditis were also observed. The most frequently noted sites are listed. Since cerebral haemorrhage follows the rupture of one or more already damaged deep arteries, as assessment was made of the part played by vascular lesions. 13 cases due to leukaemia and 35 to rupture of aneurysms of the polygon of Willis were discarded. In only 20 cases out of 138 in which convincing microscopic evidence of the vascular situation could be obtained was there an absence of significant alterations. The remaining cases consisted of serious hyalinosis (56%), fibrinoid necrosis (13%), and siderocalciosis (12%). An account is also given of the special pathogenetic conditions applicable to cerebral haemorrhage associated wtih serious gastrointestinal haemorrhage or recent myocardial infarct.

Five patients with an unusual encephalopathy, possible secondary to measles virus infection, are described. Features common to these patients are: an existing chronic disease, neurologic deterioration 2 1/2 to 6 months after a measles infection, and death several weeks later. These events occurred when the chronic disease (e.g. leukemia or neuroblastoma) was in remission. That the measles virus was the causative agent is suggested only by finding in brain and extracranial tissues intracytoplasmic and intranuclear inclusions which contained measleslike particles. Additional clinical features seen in each of the five patients were: seizures, hypertension, and the inappropriate secretion of antidiuretic hormone.

The antiprogestin RU 486 converts the early pregnant uterus by increasing the sensitivity of the myometrium to prostaglandin (PG). These effects of antiprogestin have resulted in the development of nonsurgical procedures to abort embryos based on a combination of RU 486 and different PG-analogues administered vaginally or intramuscularly. RU 486 also has a softening effect on the cervix which may be used as pretreatment in second and third trimester abortions. The effects, mode of action, dangers, and the many other postulated clinical implications (like breast cancer, meningioma, ectopic pregnancy, fetal death in utero, induction of labour, initiation and promotion of lactation, endometrial or ovarian cancers, leukemia, Cushing's syndrome, uterine adenomyosis, acute uremia, leiomyosarcoma, hypertension, etc.) are discussed.

Polycythemia vera (PV) is one of the myeloproliferative diseases, and, as such, is an example of clonal hematopoiesis. The progeny of a single, abnormal, hematopoietic stem cell gain a growth advantage over their normal counterparts resulting in overproduction of red cells generally accompanied by overproduction of granulocytes and platelets as well. There are a variety of nonspecific symptoms at onset related to the increased red cell mass and hematocrit accompanied by the more specific manifestations of pruritus, erythromelalgia, and hepatic, portal, and mesenteric vein thrombosis. Splenomegaly and hypertension are common. The laboratory hallmark is an increased red cell mass. There is also often an increase in white cell count, platelet count, and leukocyte alkaline phosphatase along with other findings reflecting the increased rate of turnover of hematopoietic cells. The bone marrow biopsy generally displays hypercellularity involving all three cell lines and absent iron stores. The diagnosis of PV depends on excluding spurious polycythemia in which there is a high hematocrit but a normal red cell mass and secondary polycythemia in which there is an increased red cell mass in response to tissue hypoxia or the inappropriate production of erythropoietin, generally by a tumor. In addition, one should try to establish the diagnosis in a positive fashion by a combination of studies of the blood and bone marrow. Phlebotomy and occasionally plateletpheresis should be used as acute therapy. Chronic therapy is guided by the knowledge that patients treated with phlebotomy alone have an increased rate of thrombotic complications particularly in older patients and those with previous thrombotic disease. Myelosuppressive therapy can reduce the incidence of these complications, but is commonly associated with an increased incidence of second malignancies, particularly acute leukemia. At present, hydroxyurea is the myelosuppressive agent of choice. Antiplatelet agents have a limited role except in the palliation of the syndrome of erythromelalgia. Median survival is approximately 10 years. As implied above, the causes of morbidity and mortality vary with the mode of chronic therapy which has been employed, leukemia being more common after myelosuppressive therapy and thrombotic complications being more common after therapy with phlebotomy alone. Ten percent to 50% of patients move into a spent phase followed by postpolycythemic myeloid metaplasia, irrespective of previous therapy employed. Eventually, the major problems may be cytopenias and massive splenomegaly.

Vincristine overdose (7.5 mg/m2) was accidentally administered to 3 children with acute lymphoblastic leukemia. Treatment included double-volume exchange transfusion, phenobarbital administered prophylactically, and folinic acid rescue 18 mg every 3 hours for 16 doses. Vincristine levels were also assayed and showed a dramatic decline in postexchange levels in the 2 patients who survived and an almost unchanged value in the patient who succumbed. Early signs of toxicity in the 2 survivors were peripheral neuropathy (day 4), bone marrow toxicity (day 5), gastrointestinal toxicity (days 6 and 7), and hypertension (days 7 and 8). Marrow aplasia lasted for 4 and 10 days, peripheral neuropathy for 15 and 42 days, gastrointestinal toxicity for 3 and 5 days, and hypertension for 5 and 14 days. The 2 children were discharged on days 13 and 16 and cytostatic therapy was restarted on days 18 and 25. Both are alive without evidence of leukemia. The third patient developed liver and marrow toxicity on day 3 and died on day 9. Postmortem examination showed leukemia infiltration of the liver and spleen.

Until recently long-term renal toxicity has not been considered a major late complication of bone marrow transplantation (BMT). Late renal dysfunction has been described in a pediatric population status post-BMT which was attributable to the radiation in the preparatory regimen. A thorough review of adults with this type of late renal dysfunction has not previously been described. Fourteen of 103 evaluable adult patients undergoing allogeneic (96) or autologous (7) bone marrow transplantation, predominantly for leukemia and lymphomas, at the Medical College of Wisconsin (Milwaukee, WI) have had a syndrome of renal insufficiency characterized by increased serum creatinine, decreased glomerular filtration rate, anemia, and hypertension. This syndrome developed at a median of 9 months (range, 4.5 to 26 months) posttransplantation in the absence of specific identifiable causes. The cumulative probability of having this renal dysfunction is 20% at 1 year. Renal biopsies performed on seven of these cases showed the endothelium widely separated from the basement membrane, extreme thickening of the glomerular basement membrane, and microthrombi. Previous chemotherapy, antibiotics, and antifungals as well as cyclosporin may add to and possibly potentiate a primary chemoradiation marrow transplant renal injury, but this clinical syndrome is most analogous to clinical and experimental models of radiation nephritis. This late marrow transplant-associated nephritis should be recognized as a potentially limiting factor in the use of some intensive chemoradiation conditioning regimens used for BMT. Some selective attenuation of the radiation to the kidneys may decrease the incidence of this renal dysfunction.

Eight hundred and fifty two cases, who were introduced from the Dental Hospital to Department of Internal medicine, Medical Hospital at Niigata, The Nippon Dental University, were examined for medical complications. About one hundred and fifty cases were introduced per year from the Dental Hospital, which consisted of about 15% of the total outpatients in the Department of Internal medicine. The age distribution showed a high incidence of patients in their 50's. The number of patients over 60 years old was 220 (25.8%), and the number of patients over 65 years old was 160 (18.8%). There was then a high percentage of elder patients. The reason for the initial medical examinations was the need for a pre-operative medical examination in 42.6% of the total cases. Concerning medical complications among the patients, the highest incidence was hypertension in 116 cases (13.6%); the second highest was hepato-biliary and pancreatic diseases in 114 cases (13.4%); and heart diseases in 81 cases (9.5%). Eighteen cases of HBs antigen positive (2.1%) were seen among the patients with liver diseases. Among those with blood diseases, anemia showed the highest incidence, and a small number had leukemia and hemophilia. Diabetes mellitus showed up in 39 cases (4.6%), most of them being more than 40 years of age. Mentally and physically handicapped patients accounted for 30 cases. Half of them were from the pre-operative examination area, like tooth extraction.
