Mycoplasmal pneumonia, tularemic pneumonia, Q fever pneumonia, psittacosis, and Legionnaires' disease are the most frequently encountered treatable atypical pneumonias. Mycoplasmal pneumonia, the most common, is often accompanied by nonexudative pharyngitis, conjunctivitis, or otitis. The nonproductive cough is characteristic. Tularemic pneumonia is characterized by substernal chest pain, bloody pleural effusion, and bilateral hilar adenopathy. Although the clinical presentation is mild, roentgenographic findings are impressive. Q fever pneumonia resembles psittacosis but is less serious; it may be accompanied by subacute bacterial endocarditis, hepatitis, or both. Psittacosis is characterized by prominent headache, bloody sputum, and relative bradycardia. Tetracycline is the drug of choice for either. In Legionnaires' disease, pneumonia is accompanied by prominent extrapulmonary symptoms. The most important diagnostic clues include diarrhea and mental confusion. Relative bradycardia and laboratory abnormalities are also helpful. Erythromycin is the drug of choice unless doubt exists as to the diagnosis.

This survey of occupationally acquired infections in clinical laboratory workers was made by questionnaires to 306 hospitals in which 698 doctors and 8654 technicians worked. There were 177 probable infections during the previous decade (1979-88). In both doctors and technicians annual incidence rate of infection was 0.2% on an average. These included 77 cases of tuberculosis, 59 cases of HBV hepatitis, 24 cases of non-A, non-B hepatitis, 6 cases of rubella, 5 cases of HAV hepatitis, 2 cases of mycoplasmal pneumonia, one case of campylobacter enteritis, one case of paratyphus, one case of salmonellosis and one case of chicken pox. There were no fatal cases. In the recent two years the occurrence of HBV hepatitis among the clinical laboratory workers apparently has decreased, but tuberculosis and non-A, non-B hepatitis occurred unchangedly. Tuberculosis occurred frequently among the staff of the pathology laboratory (40 cases) and in bacteriology (25 cases), but rarely in biochemistry (3 cases) and in hematology (one case). On the other hand, HBV hepatitis occurred frequently among the staff of the biochemistry laboratory (33 cases) and in hematology (11 cases), but rarely in bacteriology (one case). These differences showed the existence of occupational exposure, but only 20% of these cases were due to recognized accidents. According to these results infection control practices for diminishing laboratory-associated infection must be performed.

Extrapulmonary manifestations of Mycoplasma pneumoniae pneumonia are uncommon and include hematologic, gastrointestinal, musculoskeletal, dermatologic, and neurologic complications. We report a case of serologically-confirmed M. pneumoniae infection complicated by severe neutropenia, thrombocytopenia, and hepatitis. The presence of antiplatelet and antineutrophil antibodies suggested that these autoantibodies caused the cytopenias. The disease had an acute course and the patient recovered after steroid treatment. This case indicates that neutropenia, thrombocytopenia and hepatitis are possible clinical manifestations of M. pneumoniae infection.

Mycoplasma pneumonia is a major cause of respiratory infections in school-aged children. Most M. pneumonia infections in adults involve the respiratory tract. Extrapulmonary manifestations of M. pneumonia infection may be found in the skin, cardiovascular, neurologic and hematologic systems. Concomitant liver disease is rare in adults. Here, we report an unusual case of a patient who presented with fever and abdominal pain, but without pulmonary manifestations. The laboratory work-up demonstrated a hepatocellular pattern of acute hepatitis caused by M. pneumonia infection. Symptoms subsided and laboratory parameters improved with antibiotics treatment. Thus, this case can help raise clinicians' awareness of the possibility of M. pneumonia infection, with or without lung involvement, as a part of the evaluation of undetermined hepatitis.
