Only 1 case of lymphomatoid granulomatosis has previously been reported from South Africa. Experience with 4 such adult patients (2 blacks and 2 whites) is described. These patients were followed up for 15-48 months and none developed evidence of a lymphoma during this period. Fever, weight loss, cough and breathlessness were prominent symptoms in all patients. One patient, a black woman, with a diffuse interstitial pattern of lung involvement, had digital clubbing--a rare accompaniment that resolved after therapy. Dilated congestive cardiomyopathy was found in association with pulmonary nodules in a black male patient. All 4 patients were treated with cytotoxic regimens. The 2 patients treated with oral cyclophosphamide and prednisolone responded favourably. The possible explanation for paucity of reports of lymphomatoid granulomatosis from South Africa could be under-reporting, underdiagnosis or a true geographic/ethnic variation in the incidence of this condition.

The paper is concerned with observations over 3 patients in whom unusual vasculitis lay at the basis of the clinicopathological manifestations. All the patients were men of the young age. The disease debut was marked by fever, weakness, dyspnea, palpitation, cough, hemoptysis, the articulation syndrome. In two cases, there was hemorrhagic rash on the leg skin. All the patients manifested liver and spleen enlargement, two patients had lymphoadenopathy. The leading clinical symptoms included dilated cardiomyopathy, complete blockade of the inferior peduncle of His bundle and reduction of myocardial contractility. Anemia belonged to iron deficient one. The clinical examples provided indicate that immunocomplex vasculitis with evident lesions of the lungs and myocardium, not going into criteria for the known diseases, is not likely to be a casuistic rarity. Those syndromes may be associated with more or less pronounced hemosiderosis of the lungs (and, probably, of the lymph nodes, spleen and liver), with transitory or steady derangements of myocardial conduction, which attests to diffuse lesions of the myocardium possibly with both immune complexes and hemosiderin. The pathology requires further studies.

Using both transthoracic and transesophageal echocardiography we studied 13 consecutive patients with recent CT-proven ischemic stroke in which a carotid arteries high-resolution ultrasound study failed to detect thrombosis or other relevant atherosclerotic lesions in the pertinent arteries. The mean age was 53 years (range: 36-65). Two patients exhibited clinical signs of cardiac disease at physical examination i.e. absolute arrhythmia, mitral stenosis. Conventional transthoracic echocardiography allowed the detection of potential cardiac sources of emboli in 2/13 patients (15.4%): mitral stenosis in one patient and dilated cardiomyopathy in another. Transesophageal echocardiography was successfully performed without general sedation in all patients. Potential cardiac sources of emboli could be identified in 12/13 patients (92%). Left atrial thrombi were found in 3 patients: in two of them they were associated with rheumatic alterations of mitral valve leaflets; in the third patient a small thrombus was located inside a normal-sized, poorly contracting left atrial appendage. Left atrial appendage could be clearly visualized in all patients. A myxoid degeneration of a prolapsing mitral leaflet was found in 3 patients and an interatrial septum aneurysm in 2. Furthermore, at color-flow Doppler and contrast transesophageal echocardiography, 7 patients (54%) showed patency of the foramen ovale. In 5 of these patients paradoxical right to left shunting after cough or Valsalva manoeuvre could be evidenced. With reference to 11/13 patients with no clinical signs of cardiac disease at physical examination, subclinical potential cardiac sources of emboli could be detected at conventional transthoracic echocardiography in 1 and at transesophageal echocardiography in 10 patients (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

The efficacy and safety of cilazapril in chronic heart failure have been extensively investigated in an international clinical program in patients with underlying chronic heart failure with ischemic heart disease or dilated cardiomyopathy. Cilazapril in single doses of 1.25-5 mg produced a significant dose-dependent reduction in pulmonary capillary wedge pressure and systemic vascular resistance and a significant increase in cardiac index. In placebo-controlled studies, 1-5 mg of cilazapril once daily for 12 weeks prolonged predose exercise test duration and improved New York Heart Association classification status and signs and symptoms of chronic heart failure, including paroxysmal nocturnal dyspnea. Up to 86% of patients receiving these dosages had improvement, with only 12% of patients requiring the higher dose, 5 mg. These data indicate that cilazapril is effective when administered once daily to patients with chronic heart failure receiving concomitant therapy with digitalis and/or a diuretic. The safety of cilazapril in patients with chronic heart failure has been evaluated in 1,163 patients administered from 0.5 to 15 mg once daily for treatment periods ranging from 1 day to 57 months. Cilazapril was administered to 500 patients for at least 6 months, 264 patients for at least 1 year, and 101 patients for at least 2 years. The most frequently occurring adverse events were dizziness, coughing, dyspnea, fatigue, angina pectoris, and headache. Cilazapril was equally well tolerated by young and elderly patients. Treatment was discontinued due to adverse events in 12.9% of patients, mainly as a result of coughing (1.7%) and dizziness (1%). Forty-four patients (3.8%) died during cilazapril therapy or during a period without treatment. Of these deaths, 93% were due to cardiac causes, especially rhythm disturbances.(ABSTRACT TRUNCATED AT 250 WORDS)

This paper investigates the role of carnitine in the etiology and treatment of dilated cardiomyopathy in boxers. Two boxers were diagnosed as having dilated cardiomyopathy on the basis of clinical presentation, chest radiographs, electrocardiography and echocardiography. In one dog, carnitine was administered at 6.0 g (or approximately 250 mg/kg live weight (LW) daily per os, and this dog remained asymptomatic for 4 mo until it presented for anorexia, coughing and weakness. Necropsy and histologic findings were consistent with boxer cardiomyopathy in both dogs. Cardiac carnitine concentration was 567 nmol/g wet weight in the unsupplemented dog, which is below the normal mean +/- SD concentration of 1493 +/- 141 nmol/g wet weight. Low cardiac carnitine concentrations appear to be a consistent finding for dilated cardiomyopathy in boxers. However, in the dog that received carnitine therapy, cardiac carnitine was 2802 nmol/g wet weight, and all tissues assayed in the supplemented dog had higher carnitine concentrations than normal dogs. Elevation of tissue carnitine failed to ameliorate dilated cardiomyopathy in this dog. Oral carnitine supplementation in these therapeutic doses appears not to resolve dilated cardiomyopathy in all boxers.

Peripartum cardiomyopathy (PPCM) is rare cardiac complication afflicting women during pregnancy or until 5 months post partum with the typical signs of acute cardiac failure. PPCM is similar to dilated cardiomyopathy (DCM) in terms of symptoms, histopathology and treatment but is characterized by a better outcome with a high rate of spontaneous normalization of left-ventricular size and function. The understanding of the etiology is limited. However, viral myocarditis and autoimmune factors might be involved in the development of PPCM. Clinically, PPCM shows pulmonary symptoms such as dyspnea, tachypnea and coughing. The diagnosis is finally established by echocardiography. It has to be assumed that PPCM is often undetected or misdiagnosed because of the low incidence, the unspecific symptoms and the fact that other pregnancy-related factors have similar clinical appearance. The treatment is also unspecific and similar to DCM and acute cardiac failure. The severity of the disease requires an interdisciplinary approach in a perinatal center with consequent follow-up of the patients for risk stratification including echocardiography.

A 50 years old male with previous history of dilated cardiomyopathy was admitted to cardio-intensive unit with dyspnea, cough, ascites and lower limb edema ascending to the inguinal region. 2D-Ecocardiogram revealed large pericardial effusion, without signs of diastolic restriction. The patient underwent pericardial drainage, which rapidly recollected in the following day. Abdominal ultrasound showed fibrotic and reduced size liver and subsequent radionuclide scan demonstrated direct communication between peritoneal and pericardial spaces. With the resolution of ascites, pericardial effusion did not recur. Embryologic explanation of this rare condition is still elusive, but incomplete closure of diaphragmatic muscle and thoracic-abdominal communication may represent the model of this anatomic functional anomaly.

An 82-yr-old man was presented with fever and cough accompanied by generalized erythematous rash. He had taken mexiletine for 5 months, as he had been diagnosed with dilated cardiomyopathy and ventricular arrhythmia. Laboratory studies showed peripheral blood eosinophilia and elevated liver transaminase levels. Chest radiographs showed multiple nodular consolidations in both lungs. Biopsies of the lung and skin lesions revealed eosinophilic infiltration. After a thorough review of his medication history, mexiletine was suspected as the etiologic agent. After discontinuing the mexiletine and starting oral prednisolone, the patient improved, and the skin and lung lesions disappeared. Subsequently, mexiletine was confirmed as the causative agent based on a positive patch test. Drug-induced hypersensitivity syndrome is a severe adverse reaction to drugs and results from treatment with anticonvulsants, allopurinol, sulfonamides, and many other drugs. Several cases of mexiletine-induced hypersensitivity syndrome have been reported in older Japanese males with manifestation of fever, rash, peripheral blood eosinophilia, liver dysfunction without other organ involvement. Here, we report a case of mexiletine-induced hypersensitivity syndrome which presented as eosinophilic pneumonia in a Korean male.

Cardiomyopathy is an anatomic and pathologic diagnosis associated with muscle or electrical dysfunction of the heart. Cardiomyopathies represent a heterogeneous group of diseases that often lead to progressive heart failure with significant morbidity and mortality. Cardiomyopathies may be primary (i.e., genetic, mixed, or acquired) or secondary (e.g., infiltrative, toxic, inflammatory). Major types include dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, and arrhythmogenic right ventricular cardiomyopathy. Although cardiomyopathy is asymptomatic in the early stages, symptoms are the same as those characteristically seen in any type of heart failure and may include shortness of breath, fatigue, cough, orthopnea, paroxysmal nocturnal dyspnea, and edema. Diagnostic studies include B-type natriuretic peptide levels, baseline serum chemistries, electrocardiography, and echocardiography. Treatment is targeted at relieving the symptoms of heart failure and reducing rates of heart failure-related hospitalization and mortality. Treatment options include pharmacotherapy, implantable cardioverter-defibrillators, cardiac resynchronization therapy, and heart transplantation. Recommended lifestyle changes include restricting alcohol consumption, losing weight, exercising, quitting smoking, and eating a low-sodium diet.

A twelve-year-old girl presented with tachypnoea, cough and fatigue existing for 3 weeks, which subsequently proved to be caused by dilated cardiomyopathy. Echocardiography showed an echogenic mass with echolucent centre attached to the inferolateral wall of the left ventricle. There was prominent systolic dysfunction. Dilated cardiomyopathy is associated with an increased risk of intracardiac thrombosis. The intracardiac thrombi usually appear as a solid mass on the echocardiogram. The case was presented to emphasize the unususal echocardiographic appearance of an intracardiac thrombus associated with dilated cardiomyopathy.
