An optimal diet cannot yet be defined. If we knew what an optimal diet was, additional research in nutrition would not be necessary. There is abundant evidence, however, that the usual American diet is not optimal and adequate reason to recommend modification. Current dietary recommendations were developed to prevent the occurrence of nutritional deficiency disease in the 1930's and 1940's. They have been largely successful. They were made, however, before any knowledge was available about the effects of diet upon chronic disease which now represent the primary health problems of the United States. Large amounts of data are available indicating the kids of recommendations which should be made to control hypercholesterolemia--a primary risk factor of coronary artery disease. These kinds of data together with less information upon diet and cancer, hypertension, obesity, diabetes, etc. lead to sensible and consistent dietary recommendations to moderate the dietary practices of most Americans.

Valuable information was collected on the medical history and clinical course of 1273 patients entered in clinical trials with Adriamycin (ADR) carried out in 12 European cancer centers. A coded patient form was used for the data collection carried out in each center by a qualified physician following a guideline which was discussed and accepted by all of the participants. The aim of the study was to define the incidence, characteristics, and possible co-factors of the cardiomyopathy (CMP) in patients treated with combination chemotherapy regimens including ADR. The mean total dose of ADR was 268 mg/m2 (range, 15--1251 mg/m2), and 5.1% of the patients received a total dose of greater than 550 mg/m2. A "definite" ADR-related CMP was observed in 1.7% of the cases; another 3% of the cases were reported as "possible" ADR-CMP since the role played by the drug could not be clearly defined. "Definite" ADR-CMP was fatal in eight patients (0.6%) while "possible" ADR-CMP was fatal in 13 patients (1.0%). Among the possible co-factors examined, the following ones were found to be significantly associated with the occurrence of a "definite" ADR-CMP: (a) total dose of ADR; (b) vincristine when given both before and concomitantly with ADR; (c) bleomycin when given before ADR; and (d) radiotherapy to the mediastinum when given concomitantly with ADR. Furthermore, none of 182 patients receiving ADR by slow infusion developed a "definite" ADR-CMP, while 2% of the patients treated by bolus injection did so. The occurrence of a "possible" ADR-CMP was found to be significantly associated with two pre-existing pathologic conditions (electrocardiogram [ECG] abnormalities and hypertension) but not with the treatment-related co-factors for the "definite" ADR-CMP mentioned above. Other variables examined, such as sex, age, cancer type, baseline liver function, and cyclophosphamide treatment, did not seem to influence the risk of ADR-CMP. Data on ECG changes occurring during ADR treatment were also reported and their incidence was found to be strictly related to the frequency of the ECG monitoring.

Tolazoline, a drug used in the treatment of hypertension, has been described as a typical H2 agonist. In this study possible immunomodulating properties of tolazoline were investigated. A single injection of tolazoline 1 day before immunization caused an effect on delayed hypersensitivity that depended on the antigen dose. The response to 10(5) and 10(6) sheep red blood cells (SRBC) was decreased, whereas the response to 10(9) SRBC was enhanced. Administration of tolazoline 4 days after immunization predominantly affected the humoral response. The IgM response was inhibited in favour of the IgG response. Low doses of tolazoline, given to animals simultaneously with the elicitation for delayed hypersensitivity, lead to a more severe inflammation. The possible involvement of suppressor cells and vessels in tolazoline action is discussed. The application of tolazoline in the immunotherapy of human cancer is suggested.

Nine rural village communities in the jungle of Brunei, Borneo were studied to ascertain possible effects of rapid social change on the health of the inhabitants. The social mores and religious beliefs of the rural tribes--Iban, Dusun, and Punan--have undergone but little change over many hundreds of years. During the past three decades, however, enormous social pressures for change have envolved from extraordinary economic prosperity of the region, due to the exploitation of large discoveries of oil and gas. Much of the money has been invested in health care, with the result that malaria, typhus and other tropical scourges have been virtually wiped out. Child and maternal mortality have been reduced to the standards of some of the healthiest countries in the world. The young of the formerly illiterate population are being rapidly educated in new schools scattered throughout the nation. New roads are penetrating the jungle and a thriving lumber industry has been established. Motor boats for the rivers, T.V. and even a national airline have been added. Despite these incursions a vigorous proseletizing by the Moslem and to a lesser extent by the Christian church, the villagers have held tenaciously to their ancient animistic beliefs. Living in long houses, they have also been able to maintain a tightly cohesive patriarchal family structure. Against this background there is as yet little or no evidence of the major diseases of Western society--coronary artery disease and hypertension, although most forms of cancer are commonly encountered. Brunei offers a splendid opportunity to test the putative relationship of chronic vascular disease to social structure and a way of life. Future studies may be made prospectively as the almost inevitable breakdown of old customs and patterns of living occurs in the face of rapid modernization.

The jet-wash technique is an efficient method for diagnosing the endometrium carcinoma. Among 750 women we detected 50 endometrium carcinomata all of which were diagnosed by the jet-wash method. Wrongly positive findings do not exist in our series of examinations. Of the pre-stages of the endometrium carcinoma, such as adenomatous hyperplasia and adenocarcinoma in situ, however, only scarcely 50 per cent of all cases were diagnosed. The jet-wash method is also suited for outpatient clinics. Thus, patients with risk-factors for the endometrium carcinoma might be controlled annually once in outpatient clinics in addition to the usual cancer prophylactic examinations. Above all, we consider 1. patients suffering from bleeding anomalies as from the 40th year of age, 2. patients free from any symptoms, but suffering from obesity, hypertension and diabetes mellitus, 3. patients with an increased narcosis risk, 4. patients of the perimeno-pause prior to an estrogen treatment and 5. cancer post-care patients suffering from a primarily radiated endometrium carcinoma. The direct smears and the cytocentrifuge preparations can be diagnosed right on the day of examination. The thrombin cell block technique requires more work for a cytological laboratory. For a histological laboratory it might not mean any additional essential burden.

Coffee as a rule develops stimulating effects on the central nervous system, heart and circulation which are mainly caused by caffeine. In certain cases coffee may also have a sedative effect and sometimes even it is useful to fall asleep quickly. Furthermore coffee may be advantageous in the treatment of some functional disorders caused by lacking of dopamine, because coffee is able to increase the dopamine formation in brain. Concerning the effects of coffee in the gastrointestinal-tract and liver-bile system caffeine is only of secondary importance. Hereby certain roasting substances, possibly also chlorogenic acid or caffeic acid should be responsible for the stimulating effects observed in these organs. These stimulating effects could be caused whether directly or indirect e.g. by liberating gastrin or other gastrointestinal hormones. Vitamin niacin, which is formed in greater amounts from trigonelline during the roasting process, may also be important from the nutritional standpoint. Therefore coffee may be prescribed as a true drug in cases of deficiency in vitamin niacin or also in the pellagra disease. By extensive epidemiological studies performed lately it could be demonstrated that there exists no correlation between coffee consumption and certain risk factors as hypertension, heart infarction, diabetes, gout or cancer diseases. Furthermore there was no evidence that coffee or its caffeine content are able to induce genetic alterations or even malformations.

Fibrinolytic therapy was started 90 min after central retinal occlusion in a 62-year-old male patient, but the retinal function did not recover. Another patient, aged 64 years, with occlusion of a retinal artery branch, had therapy started only 6 hours after the event and showed full recovery as was documented by angiography. General contraindications against fibrinolytic therapy are: hypertension over 200 mm Hg, arteriosclerosis, diabetes with retinal changes, previous cerebral insults, malignancy or ulcer, hepatocirrhosis, recent surgical or angiographic interventions, renal insufficiency, pregnancy, cogenital or acquired abnormal blood coagulation. If these contraindications do not apply, fibrinolytic therapy of central retinal arterial obstruction is recommended provided this therapy can be started not later than 6 hours after the event. Occlusions of the central retinal vein should have fibrinolytic therapy only if there are very few haemorrhages and if the occlusion is not older than 24 hours.

After a series of studies on the linkage of reserpine with breast cancer, both evidence and interpretation appeared to be in conflict. Our case-control survey of long-term, comprehensive records from the Kaiser Foundation Medical Care Program, on 108 hypertensive breast cancer cases and 324 hypertensive controls, matched by year of birth and by race, produces a significant positive association between reserpine use and breast cancer. However, the association vanishes upon further matching with respect to the year of the first hypertension diagnosis and the subsequent length of follow-up. We thus fail to support suspicions of causality.

3 cases of adrenal cysts are reported. The incidence of cyst originating in the adrenal gland was found to be 0.02-0.06% in autopsies. Adrenal cysts are usually symptomless making the diagnosis difficult. The cases described here were diagnosed and removed at operation. One of them was associated with hypertension, and another with pregnancy, considered to be exceptional. Two of these cysts were calcified. All of them were benign. The definite preoperative diagnosis is difficult and the surgical procedure recommended is resection of the cyst with preservation of as much adrenal tissue as possible if malignancy is excluded by frozen section. Since the number of operated cases diagnosed preoperatively are too small, the possibility of treating adrenal cyst by percutaneous aspiration and injection of opaque material to eventually avoid surgery could not be established.

A questionnaire was mailed to 97,364 married women, aged 26--50, resident in Greater Boston in 1970, requesting information on lifetime oral contraceptive (OC) use, reproductive history, education, and hospitalization experience in 1969; 65,843 women responded. In 1973 a second questionnaire was mailed to 37,292 of these women, including all OC users and an equal number of non-users matched on age, parity, education, and town of residence. This questionnaire related to use of OCs, other female hormones, and the menopause. OC use was most strongly related to age, with a sixfold increase in use from the oldest women (of whom 10 per cent had used OCs at some time) to the youngest. Use was directly related to education and mobility and inversely related to parity. Reasons for beginning and ceasing use differed for women of different ages and educational attainment. Thus, use of OCs varies with social and reproductive characteristics that are risk indicators for many diseases. OC use was associated with increased risk of hospitalization for thromboembolic disease (risk ratio = 1.5, 95 per cent confidence limits 1.2, 3.2) and for mental illness, hyperthyroidism, hypertension, and cancer of the cervix. OC users were hospitalized for many non-life threatening conditions 20 to 40 per cent more frequently than were non-users.
