Of 109 cases in England and Wales in which mycobacteria of the avian-Battey group were isolated from man 89 were considered genuine infections (including 32 with Mycobacterium avium) and six were doubtful. Almost half the significant cases were lung infections in men in dusty occupations, mostly coal miners with pneumoconiosis, and just over a quarter were non-pulmonary, mostly cervical adenitis in children. The prognosis in lung infections was serious, especially in the presence of pneumoconiosis.

The routine diagnosis of tuberculosis and other mycobacterial diseases based on organism identification was completed during a period of one year in 730 patients, with serological IgG, IgM and IgA determination of antibodies against antigen 60 from M. bovis , strain BCG. The analysis was performed on 10 groups of patients consisting of 1) inflammatory diseases of the respiratory tract, 2) pericarditis, myocarditis, lymphadenitis and CNS diseases, 3) chronic non-inflammatory diseases of kidneys, liver and pancreas, 4) non-inflammatory diseases of the heart, sarcoidosis and pneumoconiosis, 5) tumor, 6) healthy people with TB contact, 7) inactive TB, 8) culture-positive pulmonary and extra-pulmonary TB, 9) culture-negative TB and extra-pulmonary TB, and 10) potentially pathogenic mycobacteria. The specificity of the test (100% negative cases in Group 6, composed of healthy people) is estimated at about 90%, in accordance with determinations made in other laboratories. In non-tuberculous patients, the specificity varied according to the analysed groups. Group 1 was largely unspecific for IgM (76% positives) but the specificity was acceptable for IgG (6.2% positives ) and IgA (7.4% positives). Group 2 was similar to Group 1. Group 3 was associated with positive IgA titers. Group 4 was only exceptiony seropositive and Group 5 was positive mainly for IgA (11. 4%) associated with lower respiratory tract ailments. This unspecific seropositivity was attributed to inapparent infections by PPM whose colonisation was favored by the particular disease of the patients. The sensitivity of serological measurements applied to the diagnosis of TB patients and PPM patients was similar, regardless if the disease was pulmonary or non-pulmonary, regardless if cultures were positive or not and, in our hands, was low (positivity for IgA about 30 %, for IgM about 10% and for IgG about 30%). This poor sensitivity observed with people presenting for treatment is attributed to an immune depression occuring mainly in elderly patients. The remarkable sensitivity of the serological instrument applied to culture-negative pulmonary and non-pulmonary TB cases as well as PPM cases makes the test a good adjuvant in cases of suspicion of TB. The assessment of the serological status of people under chemotherapy is worth the analysis, a high IgG level being associated with immunocompetence while the absence of IgG antibodies and/or the presence of IgA antibodies denotes an immunologically misdirected response potentially opening the way to chronic infections.

Anthracotic pigmentation in the bronchial mucosa has been regarded as a bronchoscopic finding of pneumoconiosis or evidence of heavy atmospheric soot. Anthracotic pigmentation with bronchial narrowing or obliteration, surrounded by calcified or noncalcified lymph nodes is typical finding of anthracofibrosis. There is a potential relationship between bronchial anthracofibrosis and tuberculosis. Tuberculous lymphadenopathy of superior mediastinum presentation with hoarseness is very rare. The paper reports a case of tuberculous mediastinal lymphadenitis with anthracosis causing vocal cord paralysis. A 66-year-old woman was admitted to our clinic with the symptoms of dry cough, hoarseness, malaise, anorexia, night sweats and with the multiple mediastinal lymphadenopathy. Fiberoptic bronchoscopy revealed left vocal cord paralysis, bronchial mucosal inflammation and multiple anthracotic plaques. Bronchial lavage and mucosal biopsy were negative for malignancy and tuberculosis. The thoracotomy was performed and a mediastinal lymph node showing caseating granulomatous inflammation with anthracosis and parenchymal anthracosis were detected. The diagnosis of anthracosis and mediastinal tuberculous lymphadenitis was made and the patients put on antituberculous treatment. But she unfortunately died in the second month of the treatment because of the abdominal complication of gastric adenocarcinoma operation.

California horses incur a bone fragility syndrome manifested by pathologic fractures. This study investigated gross, radiographic, and histologic features of the disorder as well as relationships with silicosis and levels of heavy metals and trace minerals through a postmortem study of 9 affected and 3 unaffected horses. Bones and soft tissues were evaluated grossly and histologically. Bones, lymph nodes, and lung tissue were evaluated radiographically. Tissues were evaluated for silicon levels, intracytoplasmic crystals, heavy metals, and trace minerals. All 9 affected horses had osteoporosis and clinical or subclinical pulmonary disease due to silicosis (8/9) or pneumoconiosis (1/9). All affected horses had radiographic findings consistent with osteopenia and histologic evidence of osteoporosis characterized by osteopenia, numerous resorption cavities, cement lines, and a mosaic lamellar pattern indicative of multiple remodeling events. Silicosis was characterized by widespread pulmonary granuloma formation with fibrosis; variable tracheobronchiolar and mediastinal granulomatous lymphadenitis; intracellular crystals within lung and lymph node macrophages; and pronounced lymph node fibrosis, focal necrosis, and dystrophic calcification. Crystals in lung (6/9) and lymph node (8/9) tissues were identified as cytotoxic silica dioxide polymorphs. Lung and liver tissue from affected horses had elevated levels of elemental silicon. Osteoporosis was highly correlated (r = 0.8, P < .01) with silicosis. No abnormalities in heavy metal or trace minerals were detected. This evaluation indicated that horses with bone fragility disorder have systemic osteoporosis associated with fibrosing pulmonary silicosis. The etiopathogenesis of the bone fragility syndrome is unknown; however, this study provides circumstantial evidence for a silicate associated osteoporosis.
