53 children with infective pericarditis were seen at the University College Hospital, Ibadan, between 1967 and 1976. Their ages ranged from 10 days to 15 years but 53% of them were aged 5 years and below. Cough, fever, and breathlessness were the most common symptoms; cardiac decompensation was evident in over 30% of them, 23% had muffled heart sounds, but a pericardial friction rub was audible in only one. The main pathogens identified were Mycobacterium tuberculosis (11 cases), Staphylococcus aureus (11 cases), Escherichia coli (4 cases), Pneumococcus and Pseudomonas (3 cases each). Most of the patients had some other associated infection--such as, bronchopneumonia (12 cases), empyema thoracis (10 cases), lung abscess (10 cases), septicaemis (6 cases), and osteomyelitis (3 cases). Errors in diagnosis were common, the diagnosis having been missed in 72% of the cases identified at necropsy. Even if the correct diagnosis had been made during life and appropriate treatment given, the mortality rate (36%) was high. It is suggested that the onset of cardiac failure in any child with bronchopneumonia, empyema, or lung abscess should always arouse a suspicion of infective pericarditis.

An adult, female sulfur-crested cockatoo (Kakatoe sp) was examined because of dyspnea associated with hemoptysis. On radiographic examination there was a large cystic pulmonary mass that, on aspiration, was found to contain thick sanguineous fluid. Ziehl-Neelsen staining of aspirate smears revealed numerous acid-fast organisms. Gross necropsy and microscopic findings suggested a diagnosis of tuberculosis, with primary focus of infection in the pulmonary tissues. Bacteriologic isolation and typing confirmed a diagnosis of tuberculosis and established Mycobacterium avium as the etiologic agent.

Forty-eight cases of tuberculous pleurisy were examined and the following results were obtained. (1) Most of the patients were male, and there was no significant age and underlying diseases. (2) Fever and chest pain were observed mainly in younger patients, and sputum and dyspnea in older patients. (3) All of the cases examined had exudative pleural effusion, and increased ADA activity was frequently observed. (4) Mycobacterium tuberculosis was detected in the sputum of 65%, and also in the pleural effusion of 28% of the patients. The pathological diagnosis of tuberculosis was made by pleural biopsy in 83% of the patients, suggesting that pleural biopsy is very useful in the diagnosis of tuberculosis pleurisy. (5) The prognosis of the patients with tuberculosis pleurisy was good. Steroid therapy was generally ineffective.

Disseminated mycobacterial infection was found at autopsy in a male patient with hemophilia B and acquired immunodeficiency syndrome (AIDS). In May 1986, 23 months before death, the patient had encephalitis for one month and in July he developed a fever, malaise and generalized lymphoadenopathy. Human immunosuppressive virus (HIV) was positive and the CD 4/8 ratio of lymphocyte surface markers was 0.1, but mycobacterium was not detected. In September 1986, he had severe dyspnea due to interstitial pneumonia and he was treated with high-dose methylprednisolone. He died after a 23-month course of fever, severe weight loss and terminal progressive deterioration, although he was treated with antibiotics, antifungal agents, gamma-globulin, steroid and a Azidothymidine.

A case of tuberculous pericarditis successfully managed with medical treatment alone was reported. A 78-year-old male was admitted because of cough, dyspnea and fever. Chest X-P and echocardiogram revealed massive pericardial effusion. His clinical symptoms and signs suggested cardiac tamponade. Mycobacterium tuberculosis was detected from pericardial fluid. ADA activity in pericardial fluid was high. Thoracic CT scan showed tracheobronchial, pretracheal, paratracheal and superior mediastinal lymph-node swelling. The diagnosis of tuberculous pericarditis was confirmed. Anti-tuberculous therapy consisting of INH, RFP, EB in combination with prednisolone was started. One month later pericardial effusion was controlled and six months later he was in good clinical condition without surgical treatment.

During the 11 month period up to 30 September 1987, 37 patients (26 male, 11 female, mean age 27 years) with respiratory symptoms who were human immunodeficiency virus (HIV) positive, were studied prospectively on 40 occasions to determine the cause of any pulmonary complications. HIV was heterosexually transmitted. Predominant symptoms were cough (89%), fever (89%), weight loss (83%), and dyspnoea (60%). Transnasal fibre-optic bronchoscopy (with bronchoalveolar lavage, bronchial brushings and transbronchial lung biopsies) was performed on 35 patients, twice on 3 patients. 'Tru-cut' lung biopsies were obtained from 2 patients who died before bronchoscopy. Pulmonary tuberculosis was the commonest disease, being found in one-third of the patients (12 of 37). Mycobacterium tuberculosis was cultured from 4; the remainder of the plates were contaminated. Pneumocystis carinii was present in 8 patients: as the sole pathogen in 3, with Streptococcus pneumoniae in 4, Staphylococcus aureus in 2, and one also had tuberculous lymphadenitis. Endobronchial Kaposi's sarcoma was seen in 6 of 7 patients with skin nodules. Bacterial pathogens isolated included Staph. aureus (5), S. pneumoniae (5), Klebsiella pneumoniae (2), Haemophilus influenzae (2), H. parainfluenzae (1) and Pseudomonas aeruginosa (1). Invading Aspergillus fumigatus was diagnosed by lung biopsy in one. No diagnosis was reached for 8 patients. It is concluded that in Central Africa pulmonary complications in AIDS patients are similar to those in Europe and North America but the incidence of different pathogens depends on the prevalence of pathogens in the community. M. tuberculosis is probably the commonest pathogen. This study has confirmed that P. carinii pneumonia does occur, but occurs less frequently.

Heart disease related to the acquired immunodeficiency syndrome (AIDS) encompasses a number of pathologic findings that may or may not be associated with specific cardiac signs and symptoms. A review of 30 reports revealed that cardiac disorders were apparent in 424 (74%) of 574 AIDS patients. Neoplasms and opportunistic infections each were reported in 46 (8%) patients. The area of the heart most commonly affected was the myocardium. Pericardial disease as a single disorder was apparent in 14 patients, the etiologic bases of which were Mycobacterium tuberculosis. Cryptococcus neoformans infection, and unspecified fibrinous pericarditis. Endocardial disease was histologically evident in 18 patients with nonbacterial thrombotic endocarditis, and one patient was found to have Nocardia asteroides endocarditis. Although cardiac symptoms (dyspnea and chest pains); signs (pulsus paradoxus and murmurs); or ECG, roentgenogram, or echocardiographic manifestations of AIDS may be significant, they are not generally helpful in establishing a clinical diagnosis. Echocardiograms and a heightened degree of clinical suspicion have proven useful in detecting cardiac dysfunction and life-threatening cardiac tamponade.

A 39-year-old man with pulmonary disease due to Mycobacterium xenopi is described. He had received prednisone and azathioprine for 5 years and prednisone in combination with cyclosporin A for 1 year in an effort to prevent rejection of his renal transplant. Shortly after the renal allograft was removed because of chronic rejection, the patient developed dyspnea and a decrease in vitality. He had no history of preexisting lung disease. A chest roentgenogram showed multiple nodular infiltrates in both lungs. M. xenopi was cultured from three sputum samples. The organism was susceptible to isoniazid, streptomycin, ethambutol, rifampin, pyrazinamide, and ethionamide. The patient was treated successfully with isoniazid, ethambutol, and rifampin for 3 months and with isoniazid in combination with rifampin for an additional 9 months, while he was maintained on continuous ambulatory peritoneal dialysis (CAPD). The literature on mycobacterial disease, especially in renal transplant recipients and patients on CAPD, is reviewed.

A 27-year-old white male homosexual with AIDS presented 19 months after the initial diagnosis with persistent fever, marked dyspnea at rest, and severe substernal pain in the chest. A pericardial friction rub was auscultated, and an effusion was demonstrated echocardiographically. Pericardiocentesis yielded 220 ml of serosanguinous fluid. Special stains of the fluid for microorganisms were negative. A mycobacterial infection was suspected, and therapy with multiple antimycobacterial agents was initiated. Cultures of the fluid eventually yielded MAI. Despite therapy, cardiac function declined, and the patient died two months after presentation. Autopsy confirmed the diagnosis of chronic pericarditis due to MAI. Pericarditis due to MAI should be included in the differential diagnosis of cardiac dysfunction in patients with AIDS.

Pulmonary tuberculosis (TB) continues to pose a health threat to the elderly population. In order to delineate age-related differences in disease presentation a comparison between young and old male veterans hospitalized over a five-year period with culture proven Mycobacterium tuberculosis is reported. The study sample included 27 patients 60 years of age and older (range, 60 to 85; mean, 70) and 52 patients under 60 years of age (range, 22 to 59; mean, 51). The elderly were significantly less likely to demonstrate cavitary lesions on admission radiographs or present with hemoptysis but were more likely to present with right lower lobe infiltrates and complaints of dyspnea. Symptoms prior to admission occurring with equal frequency in both young and old subjects included fever, anorexia, weight loss, and cough. Although treatment was delayed in the elderly, there were no age-related differences in mortality. Skin testing was underutilized in all patients regardless of age. The results support the notion that the clinical presentation of pulmonary TB is remarkably similar in young and old males.
