One of the major problems being researched and studied by the World Health Organization is the incidence of harmful side effects in users of steroid contraceptives. A literature search indicates that Anglo-Saxon countries report alarming hyperplastic changes, particularly in the liver, blood clots, hyperlipidemia leading to high blood pressure, porphyria, atypical leiomyomas and cervical hyperplasia. Currently attention is being focused on the relationship between steroid contraceptives and breast cancer. Fazala and Paffenbarger in their study of 1770 women found such benign changes as fibroadenoma, mastopathia fibrosa cystica and papilloma intraductale. In women who had used oral contraceptives for 2-4 yrs, malignancies were 1.9% to 2.5% more frequent than in non-users; in 6 yrs of use, 11 times greater than in non-users. Estrogens, particularly mestranol has been recognized as being harmful to the liver. Length of usage is a definite factor. Beginning with 1960, relatively frequent occurrences of hepotoma in young women on the pill were noted. Caught at an early stage, peliosis hepatis can be reversed if the patient discontinues the use of contraceptives. In some cases, even after a long interval of 6 months to 10 yrs, the disease continued to develop. Liver cell adenoma in the U. S. occurs 1/500,00 to 1/1,000,000. After 5 to 7 yrs of using oral contraceptives, the chance of developing liver cell adenoma is 5 times greater; after 10 yrs of use, 35 times greater. Hepatomas rupture in 43.4% of cases when the patient had been on a contraceptive, while in only 22.2% in cases of non-users. The literature which the author investigated did not establish a clear proof that the hyperplastic changes discussed were due exclusively to usage of oral contraceptives.

Both propranolol and adriamycin are biochemically known to inhibit mitochondrial CoQ10-enzymes of myocardial tissue in vitro. Both propranolol and adriamycin are clinically known to cause cardiotoxicity. At two dose levels of propranolol which caused no deaths to mice when administered alone, significant potentiation (p less than 0.01) of the lethality of adriamycin to mice was observed. These data, projected to the clinical situation, seem to contraindicate the administration of the beta-blocker, propranolol, for the hypertension of a cancer patient who is being treated with adriamycin.

Analysis of data from the Walnut Creek Contraceptive Drug Study showed a significant increase in risk of venous thromboembolic disease in the absence of surgery, trauma, malignancy, pregnancy, and the puerperium for women with a previous history of thromboembolism, hypertension, diabetes, varicose veins, gallbladder disease, and cigarette smoking. Education, marital status, parity, use of noncontraceptive estrogens, and obesity were not associated with an increase in risk of the disease. When only cases of the disease in the absence of all known predisposing causes (idiopathic cases) were analyzed, both oral contraceptive use and smoking remained as independent risk factors; there was no evidence of a positive interaction between them.

Various aspects of OC (oral contraceptive) use are discussed. The combination and sequential preparations are the 2 most frequently used OCs. OCs regulate hormone secretion through a "feedback mechanism" which in turn regulates ovulation. The initial choice of the type of OC to be prescribed is made according to the length and volume of and the interval between menstrual bleedings. The risk of developing thromboembolic diseases is the most freqeunt serious side effect of OC use; this is, however, influenced by several predisposing and risk factors. Hypertension has also been observed in OC users, as well as irregularities in liver function (cholestasis), the endocrine system, and glucose tolerance. There is no evidence that OC use is related to a higher incidence of cancer. Studies show that OC use has no effect on later fertility, except perhaps in the case of the abortion rate.

Nineteen patients with various solid tumors were treated with Corynebacterium parvum for 10 consecutive days at doses ranging from 0.5 to 6 mg/m2. Major toxic effects included rigors and cyanosis, hypertension, headache, nausea, and vomiting. Toxicity was maximal during the first 3 days of treatment and decreased or even disappeared when, on subsequent days, increasing doses of the vaccine were given. Objective tumor regressions were observed in four patients.

A brief survey of the literature on the side effects of oral contraceptives is given. Of the many influences on laboratory results those related to (reversible) cholestasis or to a change in protein synthesis are the most important ones. A decrease of the tolerance for glucose is sometimes observed. Few of the clinical side effects attributed to oral contraceptives can be directly correlated with the pharmaceutical action of these drugs. Many so-called side effects of the pill are due to other factors such as altered psychosociological or sexual behavior, etc. However, among users of oral contraceptives there is a significant decrease in the number of benign tumors, particularly of the breast, the uterus and the ovaries. It is still an open question if this also signifies protection against cancer. Anemias due to iron deficiency are less frequent among users of the pill. According to recent studies arterial hypertension and cholecystopathies are probably directly related to oral contraceptives, but a causal relation has not been proven for migraine, headaches, depression etc. An elevated risk for vascular complications seems to be well established: there is a 4-6-fold increase of the estimated risk for venous thrombo-embolism and a 4-9-fold increase for cerebrovascular accidents among users of oral contraceptives when compared with nonpregnant women of the same age not using the pill. Oral contraceptives act as a supplementary factor of risk which may cumulate with other similar factors, such as arterial hypertension, hyperlipidemia, overweight, smoking etc. Mortality due to oral contraceptives is very much 10-50 x) inferior to the one caused by delivery and the post partum state. Since the number of failures in prevention of pregnancies is less for oral contraceptives than for any other method of contraception, the overall risk of death under oral contraceptives in this age group of women is least.

Pathological type complications associated with 46 cases of neurofibromatosis in children under 12 are reported. It is noted that in 65.2% of the cases there are mental retardation, usually serious. More than 50% (24 cases) had some type of tumoration. All were benign with the exception of a suprarenal neuroblastoma that caused arterial hypertension and histological characteristics of malignancy. Fifteen tumors were located in the optica ways, one in the mediastinum, one in the abdomen, one in the paravertebral area, one which was a craneal plexiform tumor and four of the moluscum pendulum type on the eyelids or in neighbouring regions. Twelve children suffered from some type of seizures (Salaam's spasms, tonic-clonic, myoclonic, atonic and versive). Radiological abnormalities were very frequent in the simple X rays as well as in those in which contrast medium was used. In four cases malformations of the midline were observed, three of which were non-communicating cysts of the septum pellucidum, the other agenesis of the corpus callosum. Neurofibromatosis was further seen associated iwth Bourneville's syndrome, Morquio's syndrome, Batten's type of lipofuscinosis, facial or generalized hemihypertrophia and stenosis of the aqueduct. Heredity was dominant autosomic in 16 cases, the rest being due to possible recent mutations.

This is the first published report in Israel of ischemic colitis in a woman using the contraceptive pill; 20 such cases have been reported in other parts of the world. The patient was a 46 year old married woman with 3 children; she had been in good health except for obesity and chronic hypertension. Her medications included an oral contraceptive for a period of 3 years, and methyldopa for treatment of her hypertension. She presented with abdominal pain and diarrhea of 5 weeks duration. She underwent surgical reanastamosis of the bowel and was doing well at follow-up 1 year after surgery. The presence of ischemic colitis was definitively diagnosed by histological examination; the differential diagnosis included cancer, ulcerative colitis, Crohn's disease, and infectious disease. The authors note that although there is possible association between taking oral contraceptives and the appearance of ischemic colitis, there is not yet any statistical evidence for such a relationship. Similar cases have been reported among young women who were not using oral contraceptives.

Diseases of urban and rural Blacks in South Africa are reviewed. In rural Blacks the major problems are infection and malnutrition. Other important disorders include cancer of the oesophagus, liver and cervix, and rheumatic heart disease and cardiomyopathy. The diseases in urban Blacks are those of a population in transition. Characterised by all gradations of socioeconomic development, from the relatively primitive to the completely westernised, these people exhibit a correspondingly wide and varied range of disease embracing the afflictions of rural dwellers and the new diseases of the city. Whereas the prevalence of some of the former, such as infection and malnutrition, is declining, they still constitute a considerable problem in urban Blacks. More important is the increasingly serious impact of the new disorders, which may be divided into two groups: (a) a large range and variety of alcohol-related disorders with serious effects at the social, economic, psychological and physical levels; and (b) most, if not all, of the diseases encountered in western populations. Some of these, such as obesity and hypertension, have not only attained epidemic proportions among urban Blacks, but their prevalence may actually have exceeded that among Whites. Other conditions, such as coronary heart disease, gout, gallstones and colonic cancer, which emerged later, are relatively uncommon or rare. A plea is made for much greater epidemiological research. This is necessary in order to obtain reliable knowledge of the prevalence of disease, to determine the best ways of applying present knowledge with existing and future resources, and to obtain knowledge regarding both old and new diseases of which the pathogenesis is still obscure.

After considering the principle effects of corticosteroids on human fluids and tissues their action in the treatment of cerebral tumors is reviewed. Corticosteroids have a definite effect on cerebral and intra-tumoral edema and thus help to restore local circulation as well as C.S.F. circulation. Through these effects they diminish intracranial hypertension and reduce clinical symptoms to those of the tumor itself. They increase the time necessary for neuro-radiologic, isotopic and other investigations and make them safer, they diminish the surgical and and post-operative risks as well as those of radiotherapy. Their action on the growth of cerebral tumors remains incertain and increased survival in patients with inoperable or recurrent malignant gliomas may be due to their anti-edema effect more than to an antitumor action which remains to be determined.
