The efficacy of epanolol vs. metoprolol in stable angina pectoris was compared in 114 patients recruited to a randomized double-blind cross-over study, consisting of a 4-week period on each drug. Epanolol (200 mg) or metoprolol (200 mg) was administered daily. Bicycle ergometry was performed at the end of each treatment period. The maximum workload was 134 +/- 18 W on epanolol and 133 +/- 37 W on metoprolol (NS). Values for resting heart rate (epanolol, 72 +/- 11 beats min-1; metoprolol, 64 +/- 12 beats min-1; P less than 0.001), systolic blood pressure (epanolol, 143 +/- 21 mmHg; metoprolol, 137 +/- 21 mmHg; P less than 0.05) and diastolic blood pressure (epanolol, 88 +/- 10 mmHg; metoprolol, 84 +/- 11 mmHg; P less than 0.01) were all higher on epanolol treatment. During exercise, the increase in heart rate and blood pressure was of similar magnitude during the two treatment periods, and these parameters did not differ significantly at the last identical workload. The rating of chest pain, fatigue and dyspnoea did not differ between the two drugs during submaximal or maximal exercise. In conclusion, 200 mg of epanolol and metoprolol have similar efficacy with regard to exercise tolerance. As expected from the partial agonist activity present in epanolol but not in metoprolol, the former drug resulted in a higher heart rate and blood pressure at rest. The observed increase in these parameters during exercise was similar for both drugs.

The effects of epanolol (a new selective beta-adrenoceptor antagonist), diltiazem and placebo were compared in a group of 16 patients with chronic stable angina pectoris. Each patient received each treatment in random order. Diltiazem reduced weekly angina attack rate from 7.2 (95% CI 3.9-10.5) to 3.9 (1.9-5.9) (P less than 0.01), whereas a lesser reduction was observed after epanolol. Both drugs produced a small but significant (P less than 0.05) increase in treadmill exercise time (placebo 474 s (374-574), epanolol 527 s (431-623) and diltiazem 554 s (462-646). However, aerobic work capacity, assessed by peak achieved oxygen consumption, was not different from the placebo value of 21.2 (18.0-24.4) ml.min-1.kg-1, and clearly subnormal when compared to age- and sex-matched controls (33.0 (30.1-35.9) ml.min-1.kg-1). Ventilatory abnormalities and increased lactate levels on active treatment were observed at peak exercise only. We conclude that the cardiodepressant effects of both active drugs limit blood supply to working skeletal muscle, and that chest pain may be replaced by dyspnoea or fatigue as the limiting factors to exercise.

Carbon monoxide (CO) poisoning is the commonest single cause of fatal poisoning in the U.K. (Broome & Pearson, 1988). The clinical features are numerous and include headache, fatigue, dizziness, confusion, memory loss, paraesthesia, chest pain, abdominal pain, nausea, and diarrhoea as well as coma, convulsions and death. Without adequate treatment many patients develop neuropsychiatric sequelae including headaches, irritability, memory loss, confusion and personality changes. The diagnosis of CO poisoning is often suggested only by circumstances surrounding the victim, and remains a challenge to the A&E department. Hyperbaric oxygen therapy (HBO) is internationally accepted as the most powerful form of treatment in severe cases (Drug & Therapeutics Bulletin, 1988; Lowe-Ponsford & Henry, 1989). However, in the U.K. treatment with HBO is often not considered due to lack of hyperbaric facilities (Meredith & Vale, 1988; Anand et al., 1988), and due to inadequate awareness on the part of hospital staff. We report a case of a patient deeply unconscious as a result of CO poisoning, in which serial treatments with HBO over a period of 14 days, produced dramatic results.

We present a patient with pericardial tamponade due to amyloid heart disease. A 64-yr-old man was admitted to the hospital because of fatigue and the abrupt development of chest pain and dyspnea. Echocardiography showed severe pericardial effusion and total pericardiectomy was necessary. Ten months later laboratory studies revealed proteinuria and high serum creatinine. A rectal biopsy showed amyloid deposition that was also found in the pericardial tissue. Pericardial tamponade is an extremely rare complication of cardiac amyloidosis. To our knowledge, only one previous case of cardiac tamponade due to amyloid heart disease has been reported.

This report is an analysis of the medical records of 83 patients registered between 1960 and 1980 at Helsinki University Central Hospital as having malignant pleural mesothelioma. 65 of 83 patients had histologically confirmed malignant mesothelioma, and are the focus of this analysis. The remaining 18 (22%) patients were excluded because malignant mesothelioma was only confirmed cytologically, or because the primary tumor was not a mesothelioma. The ratio of men to women was 2:1.30 of 65 (46%) patients were not known or not likely to have been exposed to asbestos. The main symptoms at presentation were dyspnea, cough, chest pain, fatigue and weight loss. The median survival from diagnosis was 12 months, and from the onset of symptoms 18 months. Clinical stage and performance status were significant prognostic factors. Hematogenous metastases were present at autopsy in most cases. Disease and performance status therefore need to be well established and documented in clinical trials involving mesothelioma.

Cilazapril is a new once-daily angiotensin-converting (ACE) enzyme inhibitor which has been administered to 4,500 patients with mainly mild to moderate essential hypertension in a multinational clinical research program. Sitting diastolic blood pressure was reduced by about 9 mm Hg from baseline (p less than 0.01) after 4 weeks of treatment with cilazapril 1.25-10 mg/day in double-blind placebo-controlled studies. Total responder rates to cilazapril were usually 50-60% compared with 30% to placebo. Adding hydrochlorothiazide 12.5 mg/day to cilazapril 5.0 mg/day increased the total responder rate from 52 to 71%. Double-blind dose titration studies for 8 weeks showed that cilazapril 2.5-5 mg/day possessed equivalent efficacy to usual therapeutic regimens of sustained release propranolol, captopril, hydrochlorothiazide, atenolol and enalapril, Cilazapril did not affect heart rate. During long-term open administration for 52 weeks, or longer, cilazapril, either alone or in combination with hydrochlorothiazide, effectively maintained control of blood pressure. Treatment of patients with severe hypertension with cilazapril plus hydrochlorothiazide achieved a total responder rate of 73%. Adverse events were mostly observed within the first 8-16 weeks of treatment, with headache, dizziness, fatigue, nausea, cough and chest pain being the most frequent. Non-life-threatening angioedema, facial edema and mild hypotension occurred in less than or equal to 0.2% of patients, and orthostatic hypotension was reported in 2%. Abnormal laboratory test values were rarely found with cilazapril treatment. Of the 2.3% of patients with elevated serum creatinine, at any time point during the study and irrespective of outcome on continuation with cilazapril therapy, about two thirds had prior renal impairment.(ABSTRACT TRUNCATED AT 250 WORDS)

A young Japanese female demonstrated unusual features of Cushing's syndrome, cardiac myxomas and mucocutaneous lentigines. At the age of 12 years she presented with growth failure and obesity. The dexamethasone suppression test, the metyrapone test and low corticotropin concentrations indicated a primary adrenal disorder. At surgery, the adrenal glands were not enlarged (the right, 4.0 g; the left; 4.5 g) but had numerous small dark brown nodules. The pathological findings showed multiple small black cortical nodules containing large cells with eosinophilic cytoplasm and lipofuscin, and internodular cortical atrophy. These abnormalities were consistent with primary pigmented nodular adrenocortical disease. At age 22 years she complained of fatigue and palpitations associated with mid-chest pain. Four cardiac myxomas, suspected from the echocardiogram, were surgically removed. Because Cushing's syndrome and cardiac myxomas are life-threatening conditions, an awareness of the complex is important.

Primary pulmonary hypertension is usually considered a disease of younger adults. We reviewed the natural course of primary pulmonary hypertension in patients aged 65 years or greater. During an 8-year period, 63 elderly patients were discharged from our hospital with a diagnosis of pulmonary hypertension. In eight instances, an elevated mean pulmonary arterial pressure (greater than 25 mm Hg) could not be explained by secondary causes. These elderly patients with primary pulmonary hypertension had symptoms common to younger patients with this disease, including dyspnea (eight patients), chest pain (five), pedal edema (four), and fatigue (one). In all but one patient, the initial diagnosis was incorrect, and the patients were thought to have more common diseases of the elderly that cause similar symptoms. Coexisting medical problems were common and further obscured the correct diagnosis. Survival was significantly shorter in those patients with symptoms of less than 6 months' duration. Primary pulmonary hypertension should be considered in the differential diagnosis in elderly patients with unexplained dyspnea and chest pain.

Tuberculosis of the spine or ribs is uncommon, occurring in less than 1% of patients with tuberculosis (TB). 2 women are presented who recently immigrated from Ethiopia and India, respectively. One, aged 55, presented with chest pain, fatigue and several masses under the skin of the scalp. Chest X-ray and CT scan suggested Pancoast tumor, and the lateral parts of the first 2 right ribs were absent. The origin of the patient, clinical findings and positive PPD suggested TB of the ribs and anti-TB therapy resulted in cure. The diagnosis was later confirmed by a positive culture. The other woman, aged 68, presented with fatigue, mild abdominal pain and axillary lymphadenopathy. The PPD was positive and X-ray showed widening of the mediastinum. A caseating granuloma with Langhans epithelioid cells was found in a lymph node. Flaccid paraparesis developed before therapy was started. CT scan showed a typical picture of TB affecting the T3-T6 vertebrae. Drainage of a cold abscess of the spine via the anterior approach was followed by anti-TB therapy. Culture of a biopsied lymph node and of pus obtained at operation confirmed the diagnosis of TB. The patient died 2 months later from gastrointestinal bleeding. Awareness of the unusual presentations of various forms of TB is mandatory in countries with immigration from countries in which TB is still common.

We recently saw a patient who had aortitis syndrome associated with secondary amyloidosis. To our knowledge, she is the fourth report of this complication occurring in aortitis syndrome. In November 1985, the patient, a 18 year-old woman, was admitted to our hospital because of a high fever, back pain, abdominal pain and general fatigue. On physical examination, bruit was audible on the abdomen, bilateral radial artery was weakly palpable. Angiography showed the stenosis of bilateral carotid artery, subclavian artery, renal artery and superior mesenteric artery. From the above findings, she was diagnosed aortitis syndrome, and treatment was begun with prednisolone. However, she developed recurrently a high fever, chest pain, abdominal pain and exertional dyspnea. Laboratory findings at the active stage revealed the marked elevation of leukocytes, erythrocyte sedimentation rate and C-reactive protein. On her clinical course, the number of circulating thrombocytes was paralleled with the activity of the disease. On June 1988, she developed suddenly a high fever and severe pain of abdomen. Pathological findings of her stomach showed the deposition of amyloid protein A. Laboratory findings depicted the marked increment of thrombocytes, beta-thromboglobulin and platelet factor 4. These results suggest that circulating thrombocytes may play a role in product ion of amyloid protein.
