Four post-menopausal women had Cushing's syndrome due to adrenal cortical carcinomas. Comprehensive analyses of blood and urinary steroids showed that although the steroid profiles differed between patients, the pattern in each patient remained almost constant as the disease progressed, or remitted due to therapy. Elevations of serum testosterone and oestradiol were commensurate with the extent of virilisation, and the urinary output of aldosterone was associated with the severity of hypertension. A new finding was that all had substantially increased urinary free deoxycorticosterone. Complete surgical removal of the primary tumours was impossible but when most of the tumour tissue was removed, full clinical and biochemical remissions were obtained for a short time in 2 patients. One patient obtained a clinical and biochemical remission from op'DDD. In another patient the drug caused reduction both in blood pressure and in urinary aldosterone excretion, but there were unpleasant side effects. A third patient could not tolerate op'DDD. Metyrapone therapy produced neither clinical nor biochemical improvement in 3 patients. The mean duration of survival was 17 months after the first symptoms and 10 months from the date of operation. Despite advances in drug therapy, adrenal cortical carcinoma remains a lethal disease. Biochemical screening of multiple steroids offers a means of early diagnosis and disease monitoring. Extensive surgical removal of the tumour offers the best chance of a clinical and biochemical remission.

The purpose of the study was in comparison of drug use in the treatment of coronary disease or hypertension in the random selected representative population sample of Warsaw and Tarnobrzeg province . In the study women and men aged 35 to 64 years were included according to POL-MONICA studies. Among 2646 subjects studied in Warsaw 23% used drugs whereas among 2722 subjects from the Tarnobrzeg province the drug users represented 12.1%. The most frequently used drugs in the treatment of coronary disease were nitrates, curantyl and beta-blockers. The drug use in subjects with coronary disease (DDD/1000 inhabitants/day) was 4.5-fold higher in Warsaw than in the Tarnobrzeg province . The most frequently drug used in treatment of hypertension in Warsaw were beta-blockers and diuretics, whereas in the Tarnobrzeg province among men diuretic and composed drug preparations; women in the last region used frequently composed drug preparations and smooth muscle relaxants. The relationship between the use of particular drug groups and the region was significant in women. The hypotensic drug use in Warsaw was twice as high as in the Tarnobrzeg voivodship despite similar frequency of hypertension in both regions.

In this work we intend to analyze the long term effects of the classic modes of definitive cardiac pacing (VVI and DDD) on the atrial natriuretic peptide levels. A priori hypothesis is: the AV asynchrony raises the hormonal level. The design is a cross-sectional study, and the setting is the pacemaker doctor's room of a tertiary hospital. In 24 patients (17 VVI and 7 DDD) the atrial natriuretic peptide was determined by RIA. A multiple regression model was fitted to analysis. The basic result is: when several factors were controlled (age, sex, hypertension, and cardiac failure story), the atrial natriuretic peptide levels are increased in the VVI group. In conclusion, the lack of AV synchrony induced the increase of atrial natriuretic levels. For an endocrine viewpoint the DDD is more physiological pacing as well.

A case of a 29 year old man with typical picture of Cushing's syndrome is presented: pronounced hypodynamics, diabetes mellitus, hypertension, transitory psychic disorders, severe hypokalemia, metabolic alkalosis, hypercorticism, disturbed 24 h rhythm of cortisol secretion, high serum ACTH level. The treatment with steroidogenesis blockers (Metyrapone, o,p'DDD) led to a limited improvement. The well expressed organic changes in the cardiovascular and respiratory systems and pulmonary thromboembolism led to a fatal outcome. The post mortem examination revealed a pancreatic tumor 30/30 mm in size (histologically carcinoid) and enlarged hypophyseal gland with oxyphil cell hyperplasia. The electron microscopic examination found secretory granules in the pancreatic tumor cells. Concurrent ectopic secretion of ACTH by the oxyphil tumor cells is discussed.

In six districts of the Czech Republic where the MONICA programme is implemented as well as Hypertension control of the population, the authors compared the drug consumption used in the treatment of hypertension in comparable DDD/1000/D units during the period from September 1984 to August 1985 and the corresponding period two years later. For this purpose four groups were selected according to the ATC classification: diuretics, hypotensive drugs (antihypertensive drugs in the narrower sense of the word), single-component betablockers and fixed combinations of beta-blockers with hypotensive drugs. Six districts selected to match the investigated ones were selected as controls, and the drug consumption was also investigated. The results for the group of diuretics, hypotensive drugs and single component beta-blockers revealed unequivocally a greater increase of consumption in the districts included in the MONICA survey than in the control districts. Only the group of beta-blockers combined with hypotensive drugs revealed a greater increase of consumption in the control districts. The districts with the highest drug consumption in the investigated drug groups is according to other surveys the only one in the country where in recent years a decline of cardiovascular mortality, in particular cerebrovascular mortality, was recorded.

The results of a number of Polish epidemiological studies raised the importance of hypertension in the Polish population. In view of a high frequency and insufficient control of it. The detection rate of hypertension in the Warsaw population was not exceeding 59% in men and 73% in women, and treatment was undertaken in 42% and 64% of them respectively. The effectiveness of pharmacological control was 5.9% in men and 10.3% in women. The study was carried out in a representative population sample of 1309 men and 1337 women living in right-bank Warsaw districts aged 35-64 years. Hypertension was found in 515 men and 457 women. Only 132 men and 188 women were currently treated. Drugs were recorded which were taken in the last 14 days, and were grouped into pharmacological classes. The most frequently taken drugs were those blocking the sympathetic system activity (78%) and diuretics (34%). Monotherapy was used by 38.5% of patients, 32.5% took two drugs, and 7.5% took three drugs. Drug consumption was expressed in DDD for comparing the obtained data with those reported from other centres.

Since the adrenal or parathyroid cancer is a clinically rare entity. We often have difficulty in its diagnosis and treatment. The adrenocortical cancer is usually classified into two categories--endocrinologically functioning or non-functioning. The incidence is not different between them. It is often found in an advanced stage as it does not show clinical manifestation before it has grown up to a large tumor. Only an effective agent for the adrenal cancer is op'-DDD so far. Recently, cisplatin, VP-16 (etoposide) and others are administered as trial use. Most of malignant pheochromocytomas are endocrinologically active and they often cause hypertension leading to death. Therefore it is important to control hypertension in malignant pheochromocytoma. Chemotherapy and irradiation are not effective for it. Recently, 131I-MIBG (metaiodobenzylguanidine) is found to be useful not only for diagnosis but also treatment of malignant pheochromocytoma. 131I-MIBG is accumulated specifically in the chromaffin cells and with helpful to find out metastatic foci. It is also used in a large amount as a specific irradiation therapy for this malignancy. Parathyroid cancer is found in approximately 3 percent of primary hyperparathyroidism. Clinically it usually reveal serum calcium level higher than 14 mg/dl, bone lesions and renal dysfunction in addition to palpable cervical tumors adhering with skin. Sometimes it is difficult to differentiate malignancy from adenoma in histology. Most cases develop local recurrences and distant metastases in due course and dies of hypercalcemia. It is very important to control hypercalcemia in inoperable cases. As both chemotherapy and radiation therapy render no effect on this malignancy. Surgery is a sole strategy for it.

The effect of o, p'-DDD on a functioning adrenocortical carcinoma is described. A 52-year-old woman, who had a huge adrenocortical carcinoma and pulmonary metastasis, was treated by a low-dose administration of o, p'-DDD, which reduced the tumor size. The excretion of urinary 17-OHCS was decreased, whereas plasma cortisol was not decreased but rather increased. This was considered to be caused that o, p'-DDD functioned as a cytotoxic factor which did not improve the states of hyperkalemia, hyperglycemia and hypertension. This suggested that monitoring to measure multiple steroids in addition to plasma cortisol and urinary 17-OHCS was useful for recognizing the general conditions of patients with adrenocortical carcinoma receiving o, p'-DDD therapy.

To determine whether survival following permanent ventricular demand pacing differs from survival following permanent dual-chamber pacing in patients with symptomatic sinus node dysfunction (unexplained sinus bradycardia, subsidiary rhythms, sinus arrest, sinoatrial block, or the bradycardia/tachycardia syndrome), we followed 79 patients who received a VVI pacemaker (group 1) and 49 patients who received a DVI or DDD pacemaker (group 2) for 1 to 5 years. There was no significant difference in sex distribution, mean age, or the incidence of coronary heart disease, hypertension, valvular heart disease, diabetes mellitus, stroke, or renal failure between groups 1 and 2. Overall, the predicted cumulative survival rates at 1, 3, and 5 years were 89%, 82%, and 74%, respectively, for group 1 and 94%, 86%, and 78%, respectively, for group 2. In patients with preexistent congestive heart failure (CHF), predicted cumulative survival rates at 1, 3, and 5 years were 78%, 69%, and 57%, respectively, for group 1 (n = 23) and 90%, 83%, and 75%, respectively, for group 2 (n = 16). Five-year predicted cumulative survival was significantly lower in group 1 patients with CHF than in group 2 patients with CHF (p less than 0.03). There was no significant difference in 5-year cumulative survival rates between groups 1 and 2 in patients without CHF. The results suggest that permanent dual-chamber pacing enhances survival to a greater extent than permanent ventricular demand pacing in patients with chronic symptomatic sinus node dysfunction and CHF.

To determine whether survival after permanent ventricular demand (VVI) pacing differs from survival after permanent dual chamber (DVI or DDD) pacing in patients with chronic high degree atrioventricular (AV) block (Mobitz type II or trifascicular block), 132 patients who received a VVI pacemaker (Group 1) and 48 patients who received a DVI or DDD pacemaker (Group 2) were followed up for 1 to 5 years. There was no significant difference in sex distribution, mean age or incidence of coronary heart disease, hypertension, valvular heart disease, diabetes mellitus, stroke or renal failure between Groups 1 and 2. Overall, the predicted cumulative survival rate at 1, 3 and 5 years was 89, 76 and 73%, respectively, for Group 1 and 95, 82 and 70%, respectively, for Group 2. In patients with preexistent congestive heart failure, the predicted cumulative survival rate at 1, 3 and 5 years was 85, 66 and 47%, respectively, for Group 1 (n = 53) and 94, 81 and 69%, respectively, for Group 2 (n = 20). The 5 year predicted cumulative survival rate was significantly lower in Group 1 patients with preexistent congestive heart failure than in Group 2 patients with the same condition (p less than 0.02). There was no significant difference in 5 year cumulative survival rate between Groups 1 and 2 for patients without preexistent congestive heart failure. The results suggest that permanent dual chamber pacing enhances survival to a greater extent than does permanent ventricular demand pacing in patients with high degree AV block and preexistent congestive heart failure.
