A case of IBL-like T cell lymphoma with serum monoclonal gammopathy was reported. A 58-year-old woman, who had suffered from heart failure, was admitted because of asthma attack, fever and lymphadenopathy. Leucopenia with a small amount of atypical lymphocytes was detected. Serum analysis showed monoclonal elevation of IgM-kappa (M-protein) and hyperviscosity. Urinary Bence-Jones protein was detected. Lymph node biopsy revealed the disappearance of normal structure and proliferation of T cells with pale cells which characterized IBL-like T cell lymphoma. Immunocytochemistry revealed the pale cells to bear T cell markers (MT-1, CD 5, CD 8 or CD 4) and IgM-positive cell distribution. Tonsilar biopsy showed the infiltration of atypical lymphoids and pale cells. Bone marrow biopsy showed moderate lymphoplasmacytoid proliferation with lymph follicles. Clinical data and serum analysis suggested macroglobulinemia. Additional lymph node biopsy was performed and revealed IBL-like T cell lymphoma. IBL-like T cell lymphoma is characterized by polyclonal hypergammaglobulinemia. The present case probably occurred initially as IBL-like T cell lymphoma and lymphoplasmacytoid cell proliferation might have followed due to an excess of CD 4+ cells.

Salbutamol (albuterol) is a beta 2-selective adrenoceptor agonist which accounts for its pronounced bronchodilatory, cardiac, uterine and metabolic effects. During the intervening years since salbutamol was first reviewed in the Journal (1971), it has become extensively used in the treatment of reversible obstructive airways disease. Numerous studies in this disease (including severe acute, childhood and exercise-induced asthma) have confirmed the bronchodilatory efficacy of salbutamol, and it has been shown to be at least as effective as most of the currently available bronchodilators, if not more effective. The onset of maximum effect of salbutamol is dependent on the formulation used and the route by which it is administered. In most patients inhaled salbutamol is a first-line therapy, since it offers rapid bronchodilation, usually relieving bronchospasm within minutes. Although oral salbutamol has often proved to be less efficacious than the inhaled formulation, it still affords clinically significant bronchodilation, and it is particularly useful in those patients unable to coordinate the use of inhalers. Parenteral formulations of salbutamol are generally reserved for the treatment of severe attacks of bronchospasm and they are one of the treatments of choice in these life-threatening situations. Studies of the concomitant use of salbutamol and other agents such as anticholinergics, methylxanthines and beclomethasone dipropionate have usually shown a complementary response in the majority of patients, as might be expected from the different mechanisms of action of these groups of drugs. Salbutamol is generally well tolerated and any side effects observed are a predictable extension of its pharmacology. Since the frequency of side effects is dose related, and therefore dependent on the route of administration, it is not surprising that they are much more common following intravenous and oral rather than inhalation therapy. Tremor, tachycardia and hypokalaemia are the most frequently reported adverse effects. After nearly 20 years of use, salbutamol is well established as a 'first-choice' treatment in reversible obstructive airways disease. Indeed, throughout this time many new bronchodilatory agents have been studied but none have proved more effective. Clinical evaluation of salbutamol in the treatment of premature labour, hyperkalaemia and cardiac failure awaits further studies, although to date some encouraging results have been reported.

The relationship between angiotensin converting enzyme inhibitors (ACE inhibitors) and the development of cough was studied in 80 patients. Cough developed in 25 (31%). Seventeen patients had detailed respiratory investigations of whom 12 developed a new cough. Five of the 12 patients had a remission on placebo and recurrence on rechallenge. Cough does occur with ACE inhibitors but there are other possible causes of cough such as asthma, bronchitis, smoking and heart failure. The true incidence of new cough with ACE inhibitors is uncertain at present.

Lignocaine (lidocaine) and beta-adrenoceptor antagonists are widely used after acute myocardial infarction. The therapeutic value of these agents depends on the achievement and maintenance of safe and effective plasma concentrations. Lignocaine pharmacokinetics after acute myocardial infarction (MI) are controlled by a number of variables. The single most important is left ventricular function, which affects both volume of distribution and plasma clearance. Other major factors include bodyweight, age, hepatic function, the presence of obesity, and concomitant drug therapy. Lignocaine is extensively bound to alpha 1-acid glycoprotein, a plasma protein which is also an acute phase reactant. Increases in alpha 1-acid glycoprotein concentration occur after an acute MI, decreasing the free fraction of lignocaine in the plasma and consequently decreasing total plasma lignocaine clearance without altering the clearance of non-protein-bound lignocaine. Complex changes in lignocaine disposition occur with long term infusions, and therefore early discontinuation of lignocaine infusions (within 24 hours) should be undertaken whenever possible. Because the risk of ventricular tachyarrhythmia declines rapidly after the onset of an acute MI, lignocaine therapy can be rationally discontinued within 24 hours in most patients. Lignocaine has a narrow toxic/therapeutic index, so that pharmacokinetic factors are critical in dose selection. In contrast, beta-adrenoceptor antagonists' adverse effects are more related to the presence of predisposing conditions (such as asthma, heart failure, bradyarrhythmias, etc.) than to plasma concentration. The pharmacokinetics of beta-adrenoceptor antagonists are important to help assure therapeutic efficacy, to provide information about the anticipated time course of drug action, and to predict the possible role of ancillary drug effects (such as direct membrane action) and loss of cardioselectivity. Lipid solubility is the main determinant of the pharmacokinetic properties of a beta-adrenoceptor antagonist. Lipid-soluble agents like propranolol and metoprolol are well absorbed orally, and undergo rapid hepatic metabolism, with important presystemic clearance and a short plasma half-life. Water-soluble drugs like sotalol, atenolol, and nadolol are less well absorbed, and are eliminated more slowly by renal excretion. Clinical assessment of beta-adrenoceptor antagonism is more valuable than plasma concentration determinations in evaluating the adequacy of the dose of a particular beta-adrenoceptor antagonist.(ABSTRACT TRUNCATED AT 400 WORDS)

Factors influencing the prognosis were studied in 165 patients with polyarteritis nodosa (PAN) and Churg-Strauss angiitis. One hundred and forty-seven of the patients fulfilled histological and/or arteriographic diagnostic criteria, and in 18 patients the diagnosis was based on clinical criteria. The patients' mean age on diagnosis was 48.4 +/- 16.4 years. The main symptoms were fever (69%), weight loss (66%), arthritis (44%), mononeuritis multiplex (67%), cutaneous signs (46%), renal involvement (26%), gastrointestinal symptoms (31%), asthma (29%), hypertension (31%) and cardiac failure (18%). Ninety-two per cent of the patients survived for at least 1 year after diagnosis of the disease, 79% for 2 years, and 63% for 5 years. The immediate causes of death were gastrointestinal bleeding or peritonitis in 11 cases, pancreatitis in two, renal insufficiency in six, cardiac failure in five, infectious complications in four, stroke in three and other causes in 11. We studied the prognosis of necrotizing angiitis in relation to clinical symptoms and laboratory findings. The association of four conditions were associated with a poor prognosis: age over 50, gastrointestinal problems, cardiomyopathy and renal signs. The survival rates in patients with these conditions were: for gastrointestinal problems, 55% 5-year survival (versus 67%); and for age over 50, 68% 3-year survival (versus 78%; p less than 0.09). One hundred and fifty-nine patients were treated with steroids for at least 18 months. Forty-eight also received cytotoxic agents (27%) and 46 plasma exchange. Patients who were treated with plasma exchange and prednisone were randomly assigned to additional treatment with cyclophosphamide. Survival rates were comparable in both groups.

Xamoterol is a partial agonist at the beta 1-adrenoceptor. Haemodynamic studies indicate that xamoterol moderately increases myocardial contractility, improves diastolic relaxation and lowers left ventricular filling pressure at rest and during moderate exercise. At higher levels of sympathetic activity (e.g. strenuous exercise) it produces negative chronotropic responses whilst the reduced filling pressure is maintained. Studies in patients with mild to moderate chronic heart failure demonstrate an advantage for xamoterol 200mg twice daily over placebo and digoxin with respect to improvement in exercise capacity and symptoms. In limited trials to date the initial response seems to be maintained during periods of up to 12 months. Preliminary small studies suggest that xamoterol is useful in the treatment of some patients with angina pectoris, sinoatrial disease or postural hypotension, although further studies are needed to confirm its clinical role in such patients. Xamoterol appears to be generally well tolerated, but deleterious effects in a small number of patients with asthma, or severe heart failure due to dilated cardiomyopathy indicate the need for cautious use of xamoterol in patients with these diseases. Thus, xamoterol is a promising addition to the drugs available to the physician for treating patients with mild to moderate heart failure although further controlled studies are required to clearly establish its precise role.

1. Beta-Blockers are of similar efficacy in the treatment of hypertension to other antihypertensive drugs of first choice; they have a wide spectrum of activity both alone and in combination. 2. Although beta-blockers first appear to worsen the haemodynamic changes of hypertension, subsequently peripheral resistance falls. The cardiovascular reflexes responsible for the responses of posture or other responses requiring normal functioning of alpha-mediated tone are not inhibited. 3. Important contra-indications are asthma and heart failure in susceptible subjects. Lipid soluble drugs have somewhat greater CNS side effects. 4. Triglyceride levels, notably an increase in VLDL and a fall in HDL occur from non-selective agents (less so from beta 1-selective agents) and there is a marginal effect from drugs with relatively high ISA. 5. In contrast to other antihypertensive drugs beta-blockers reduce the myocardial infarction rate in high risk patients (i.e. post-myocardial infarct). Results in primary prevention of mild hypertension have been less promising. 6. Those drugs which are lipid soluble and liver metabolized result in greater variation of plasma concentration after oral administration and some pharmacokinetic drug interactions. Once daily administration is possible with many beta-blockers. 7. beta-Blocking drugs have an established and proven place in the treatment of hypertension.

1. This author believes that the present evidence (water shifts and vasodilatation) strongly indicates that low osmolality is probably the main advantage of the new contrast media. 2. Arteriographic adverse reactions (pain, vasodilatation) are less marked with the contrast medium of the lowest osmolality--i.e. ionic ioxaglate salts. 3. Minor adverse reactions (nausea and vomiting) are less marked with some non-ionic media (e.g. iohexol, iopamidol) than with ioxaglate but there are no data concerning the relative incidence of severe reactions or fatalities. 4. Dr. Lasser's suggestion in 1987, that 12 hours of corticosteroid prophylaxis reduces the adverse reaction rate of intravenous HOCM to the rate of LOCM reactions, awaits confirmation. However, corticosteroid prophylaxis will not reduce the side effects due to hyperosmolality, e.g. vasodilation, hypervolemia, and pain (on arterial injection). 5. Unless and until the necessary finances are available, I suggest LOCM (costing 12 times the price of HOCM in Canada and America) be used on a selective and discriminatory basis in three groups of patients: those undergoing painful procedures (e.g. peripheral arteriography), those undergoing potentially dangerous procedures (e.g. spinal angiography, coronary angioplasty) for patients considered on account of their previous medical history (e.g. asthma, allergy, previous adverse reactions, cardiac failure) to be at greater risk than the normal population.

The role of serotonin in the pathogenesis of hypertension is interesting, and its investigation is much in vogue at present. This study compared the hypotensive effect of ketanserin, a specific 5-hydroxytryptamine receptor antagonist, with metoprolol in essential hypertension. On a double-blind basis, one treatment group (19 patients on ketanserin) was compared with another (21 patients on metoprolol). There was a significant reduction in diastolic blood pressure with both ketanserin and metoprolol (P less than 0,001). Side-effects were insignificant. One patient on metoprolol and 2 on ketanserin complained of dizziness. The dose of ketanserin was 40 mg twice a day and that of metoprolol 100 mg twice a day. Ketanserin does not appear to cause abnormal haematological values or biochemical adverse effects. It can be given to hypertensive patients with cardiac failure or bronchial asthma without adverse effects and may improve the peripheral vascular status of a hypertensive patient.

In 5 years, 41 cases of chronic pulmonary heart were observed at the University Hospital Ignace-Deen in Conakry, representing 7.14 p. cent of hospitalized patients, thus ranking 4th after Hypertension, various myocardiopathies, and valvulopathies. These patients are from a rural background in 65.21 p. cent of the cases. Chronic bronchitis, 4 p. cent of the cases, and bronchial asthma, 27 p. cent of the cases, represent the main causes. An important factor is that all patients were hospitalized with heart failure, at different stages of NYAH.
