A 28 year old veterinary medical student experienced spiking fever, cough, peripheral blood eosinophilia and an eosinophilic pulmonary infiltrate. Corynebacterium pseudotuberculosis was isolated from a transtracheal aspirate and bronchoscopy washings. C. pseudotuberculosis, a pathogen responsible for lymphadenitis in livestock, has never been reported to cause pneumonia in man. In the four cases of C. pseudotuberculosis previously reported, lymphadenitis was the chief clinical presentation. In our patient specific antibodies against the isolated C. pseudotuberculosis developed but not against the other corynebacteria. With erythromycin therapy, the peripheral blood eosinophilia and IgE anti-C. pseudotuberculosis titer decreased whereas the IgG titer continued to increase.

Parasite-free pony foals (n = 10) were infected orally with 1000,000 Parascaris equorum embryonated eggs. One pony foal each was euthanatized on days 1, 3, 5, 7, 11, 16, 23, 27, 42, or 80 after infection. Foals infected for more than 7 days showed signs of coughing, anorexia, rough coat, and weight loss. Cellular changes in the blood were mild anemia, marked eosinophilia, and leukopenia. Gross postmortem lesions included hemorrhage, edema, and white-to-yellow necrotic foci (0.5 to 1.00 mm) in lungs, liver, and bronchial and hepatic lymph nodes. Microscopically, the liver was hemorrhagic and had focal necrosis and eosinophilic granulomas. Eosinophilic lymphadenitis with edema was in the hepatic and bronchial lymph nodes. The lungs had focal areas of necrosis with hemorrhage and interstitial pneumonia with hyalinization of the alveolar walls. Larvae were first seen in the liver at postinfection hour 24 and in the lungs on postinfection day (PID) 11. Average length of larvae in the liver was 1 mm and 2.5 mm in the lungs. Larvae were not found in the liver after PID 11 or in the lungs after PID 42. The migratory pathway of P equorum was similar to that of Ascaris lumbricoides because the larvae migrated via lymph and blood vessels to the liver and then to the lungs. After migrating through the lungs, the larvae were coughed up and swallowed and then developed in the small intestine.

Forty-three cases of toxoplasmic lymphadenitis were studied. They constituted 0.5% of all lymph node biopsies and 4.2% of reactive lymphadenitis. The histological findings supporting a diagnosis of toxoplasmosis were correlated with serological studies. The condition primarily affects young men, causing cervical lymph node enlargement and varying degrees of fatigue, malaise, cough and fever. It is usually self-limited. This study emphasizes the need for clinicians to consider toxoplasmosis in the differential diagnosis of lymphadenopathies.

For a period of 11 years and 7 months (1st January 78-31 July 89), 1950 lymph nodes were received in the pathology laboratory of Cameroon. 333 of these, that is 17% revealed typical lesions of tuberculosis. Analysing the information associated to these tuberculoid adenitis revealed that: 46% of the patients were less than 10 years of age; 83.8% of the specimens were taken from the cervical region. 78% of patients had fever, cough was complained of by 56% and 40% had polyadenopathies. Finally, 81% of the tuberculoid lymph nodes analyzed had a diameter less than 5cm while only 33% showed acid fast bacilli on direct examination (Ziehl-Neelsen staining method) on the histologic slides.

A 16-year-old male was admitted with a history of cervical lymph node swelling, high fever, cough and hemosputum. On admission, bilateral cervical lymph nodes swelling and fine crackles in the right lower lung field were noted. A chest X-ray film showed an infiltrative shadow in the right lower lung field and right hilar enlargement. Cervical lymph node biopsy specimens revealed wide areas of necrosis with nuclear debris. Transbronchial lung biopsy showed infiltration of lymphocytes in the interstitium and bronchoalveolar lavage fluid showed increased T-lymphocytes and a decreased T4/T8 ratio. The patient was diagnosed to have subacute necrotizing lymphadenitis with T-lymphocyte alveolitis. Additionally, antinuclear antibodies were positive, and anti HTLV-I antibody was false positive. These findings suggested an immunological abnormality in this case. His cervical lymph node swelling and infiltrative shadow on chest X-ray film improved with steroid therapy. Our case may be the first case of subacute necrotizing lymphadenitis with T-lymphocyte alveolitis.

The antibiotic era has changed the incidence, causal factors, and gravity of empyema. Between 1977 and 1988, 27 children with empyema were surgically managed. Ten cases occurred after an operation (8 esophageal and 2 abdominal). There were 15 girls and 12 boys. The age range was newborn to 12 years. Symptoms included fever, cough, tube drainage postoperatively, anorexia, weight loss, chest pain, tachypnea, and lymphadenitis. Multiple aerobic and anaerobic organisms were cultured. Treatment included thoracentesis and antibiotics, tube thoracostomy, tube thoracostomy and bronchoscopy, decortication, or decortication with lobectomy. The total hospital stay averaged 28.3 days, and after decortication, 11.6 days. Empyemas in children frequently have multiple organisms and should be treated with broad-spectrum antibiotics while awaiting culture results. Thoracentesis and tube thoracostomy are often ineffective in curing the disease. Decortication can abbreviate hospital stay if performed promptly for persistent pleural sepsis.

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.

Among 137 members of 30 families, 6% (and 8% of those aged under 15 years) were seropositive for toxocara antibodies. In these seropositive subjects and in 84 patients known to have raised toxocara titres the commonest clinical features were abdominal pain, hepatomegaly, anorexia, nausea, vomiting, lethargy, sleep and behaviour disturbances, pneumonia, cough, wheeze, pharyngitis, cervical adenitis, headache, limb pains, and fever. 61% of patients with raised toxocara titres had recurrent abdominal pain. Eosinophilia was in many cases associated with a raised toxocara titre, but 27% of patients with high titres had normal eosinophil counts. Toxocariasis is common, especially in children, and is associated with clinical features that are generally regarded as non-specific but together form a recognisable symptom complex. Toxocariasis should be considered in the differential diagnosis of such symptoms and especially in recurrent abdominal pain, which might otherwise be labelled as idiopathic. The absence of eosinophilia does not exclude toxocariasis.

Mediastinal fibrosis, the most serious late complication of remote infection by Histoplasma capsulatum, is a thick, dense fibrotic capsule which surrounds a small mediastinal focus of old caseous adenitis. The fibrotic process may accrue over prolonged periods and extend within the lumina of critical mediastinal structures to produce complete occlusion. We summarized clinical and radiographic data for 71 patients with mediastinal fibrosis; the criteria for inclusion were the clinical demonstration of occlusion of major central airways (trachea or mainstem bronchus) or major vessels (pulmonary arteries or veins) and the absence of other disease processes which might cause such obstruction. We selected 65 patients who met these criteria from the medical literature of the last 40 years and report 6 new cases from our experience. The majority of patients were diagnosed between ages 20 and 40. The most common symptoms included hemoptysis, dyspnea, and cough. An accentuated pulmonic component of the second heart sound, wheezing, and localized murmur were among the physical findings reported. Radiographic abnormalities consisted of mass lesions and atelectasis or infiltrates, but were often nonspecific. Chest radiography was deceptively normal in some patients, even in the presence of major central airway or vascular occlusion, especially when the focus was subcarinal. Computed tomography has particular promise to depict the mediastinal abnormalities in this process. Surgery had minimal therapeutic benefit. Because of incomplete followup, the mortality of 30% in this series surely does not represent the true overall mortality of mediastinal fibrosis.

Sixteen of 32 Friesian calves, 8 to 10 weeks old, died over 4 weeks. The calves were housed in pens previously used by dogs. Clinical signs included anorexia, pale mucous membranes, rapid weight loss, coughing and palpably enlarged superficial lymph nodes. At necropsy, calves were emaciated and had generalised enlargement of lymph nodes, pale mottling of skeletal muscles, excess peritoneal, thoracic and pericardial fluid and subpleural and subepicardial haemorrhages. Histologically there was a lymphadenitis, myositis, myocarditis, glomerulonephritis, interstitial pneumonitis and encephalitis. Schizonts of a sporozoan parasite, presumably Sarcocystis cruzi were found in the endothelial cells of blood vessels in many organs.
