1/144. Severe mycoplasma pneumoniae pneumonia.

    Four cases of severe mycoplasma pneumoniae infection are reported which were treated in a single hospital over the course of 4 years. The difficulties in the diagnosis of M. pneumoniae infections are eminently demonstrated by these cases. Because of the fact that it generally takes 2-o weeks to make this diagnosis, the physician must utilize clues of limited reliability. If gram stains and culture of sputum fail to demonstrate any bacterial pathogen and the patient has a chest X-ray compatible with this diagnosis as well as a white blood count less than 15,000/mm3, M. pneumoniae infection may be present. A good antimicrobial choice in such a situation is erythromycin. ( info)

2/144. mycoplasma penetrans bacteremia and primary antiphospholipid syndrome.

    mycoplasma penetrans, a rare bacterium so far only found in hiv-infected persons, was isolated in the blood and throat of a non-hiv-infected patient with primary antiphospholipid syndrome (whose etiology and pathogenesis are unknown). ( info)

3/144. mycoplasma pneumoniae-associated bronchiolitis causing severe restrictive lung disease in adults: report of three cases and literature review.

    STUDY OBJECTIVES: To characterize adult mycoplasma pneumoniae-induced bronchiolitis requiring hospitalization. DESIGN: We encountered an adult patient with severe bronchiolitis in the absence of pneumonia due to M. pneumoniae. To determine the relative frequency of such a condition, we retrospectively reviewed the medical records of adults over a 4-year period with a hospital discharge diagnosis of "bronchiolitis" from a university hospital. SETTING: University Hospital of the University of colorado health Sciences Center, Denver, CO. Study subjects: From 1994 to 1998, 10 adult inpatients were identified with a diagnosis of bronchiolitis. There were two with respiratory bronchiolitis, one with panbronchiolitis, one patient with bronchiolitis obliterans organizing pneumonia (BOOP), and six with acute inflammatory bronchiolitis. Including the initial patient, three had a definitive clinical diagnosis of Mycoplasma-associated bronchiolitis. RESULTS: The three adult patients with bronchiolitis due to M. pneumoniae are unusual because they occurred in the absence of radiographic features of a lobar or patchy alveolar pneumonia. Hospital admission was occasioned by the severity of symptoms and gas exchange abnormalities. One patient had bronchiolitis as well as organizing pneumonia (BOOP) that responded favorably to corticosteroid treatment. The other two had high-resolution CT findings diagnostic of an acute inflammatory bronchiolitis. One of the patients with inflammatory bronchiolitis had an unusual pattern of marked ventilation and perfusion defects localized predominantly to the left lung. All three had restrictive ventilatory impairment on physiologic testing. CONCLUSIONS: In adults, Mycoplasma-associated bronchiolitis without pneumonia is rarely reported, but in hospitalized patients, it may be more common than expected and may be associated with severe physiologic disturbances.

4/144. Infection of a traumatic pelvic hematoma with mycoplasma hominis.

    fever developed in a previously healthy young man who had sustained extensive pelvic trauma. mycoplasma hominis was isolated in pure culture from six of seven specimens taken from a retroperitoneal hematoma over a one-week period, and mycoplasmacidal antibodies were present in high titer in the convalescent-phase serum. The fever abated after thorough surgical drainage of the infected hematoma. ( info)

5/144. mycoplasma hominis bacteraemia not associated with genital infections.

    We describe two cases of systemic infection with M. hominis without prior genital infection and review the previous literature on this condition. ( info)

6/144. Acute encephalopathy and intractable seizures in a 10-year-old boy.

    We report a 10-year-old child with Robinow's syndrome who had a 2-week history of headaches and dizziness. On the day of admission, he developed a focal onset seizure with rapid secondary generalization. The seizures were intractable despite adequate doses of benzodiazepine, phenytoin, and phenobarbital, requiring a pentobarbital drip. Continuous electroencephalogram (EEG) monitoring showed persistence of the epileptiform discharges for 13 days. cerebrospinal fluid and brain biopsy studies were unrevealing. Mycoplasma pneumonia titers showed elevation of both immunoglobulins G and M that doubled during the tenth hospital day. High-dose methylprednisolone was begun, and within 12 hours of initiation the patient sat up and began to follow commands appropriately. The overall EEG background markedly improved. central nervous system mycoplasma pneumoniae infection should be suspected in patients with an encephalopathy of unclear etiology. ( info)

7/144. life-threatening mycoplasma hominis mediastinitis.

    mycoplasma hominis infections are easily missed because conventional methods for bacterial detection may fail. Here, 8 cases of septic mediastinitis due to M. hominis are reported and reviewed in the context of previously reported cases of mediastinitis, sternum wound infection, pleuritis, or pericarditis caused by M. hominis. All 8 patients had a predisposing initial condition related to poor cardiorespiratory function, aspiration, or complications related to coronary artery surgery or other thoracic surgeries. mediastinitis was associated with purulent pleural effusion and acute septic symptoms requiring inotropic medication and ventilatory support. Later, the patients had a tendency for indolent chronic courses with pleuritis, pericarditis, or open sternal wounds that lasted for several months. M. hominis infections may also present as mild sternum wound infection or as chronic local pericarditis or pleuritis without septic mediastinitis. Treatment includes surgical drainage and debridement. Antibiotics effective against M. hominis should be considered when treating mediastinitis of unknown etiology. ( info)

8/144. Retroperitoneal abscess and bacteremia due to mycoplasma hominis in a polytraumatized man.

    We report a case of a retroperitoneal abscess due to mycoplasma hominis in a young polytraumatized man who developed septicemia under treatment with rifampin and flucloxacillin. M. hominis was recovered from blood cultures as well as from the abscess near the left iliac spine. After 10 days of therapy with clindamycin the patient improved, and intraoperatively taken swabs were culture negative but still positive by PCR. ( info)

9/144. Recurring aseptic meningitis after travel to the tropics: a case of Mollaret's meningitis? Case report with review of the literature.

    Recurrent aseptic meningitis in a 35-year-old caucasian woman is described. She had many attacks over a period of 9 years. The first attack occurred after travel in the tropics. In spite of extensive examinations no cause could be found for the recurrent attacks. Both the clinical presentation and characteristics of the cerebrospinal fluid are compatible with the diagnosis of Mollaret's meningitis. There is no known cure for this condition, although colchicine and indomethacin have been mentioned to relieve symptoms. In our patient, a treatment with indomethacin during the last attack resulted in a clear and rapid improvement of symptoms. Since this episode only mild relapses have occurred, all of which responded well to the same treatment. This case highlights the long time span in which attacks of Mollaret's meningitis can occur, and the spectacular benefit of indomethacin. ( info)

10/144. mycoplasma pneumoniae infections and exanthems.

    A review of the medical literature and two case reports of M. pneumoniae infections with exanthems are presented. Erythematous maculopapular and vesicular exanthems were most common. The duration of rash was more than seven days in the majority of instances, and most patients had associated pneumonia. A striking difference in prevalence and clinical symptomatology by sex was noted; 16 of 20 patients analyzed were males, and they frequently dad severe mucocutaneous syndromes. In contrast, severe conjunctivitis, generalized ulcerative stomatitis, and vesicular or bullous exanthems were not seen in females. Clinicians should suspect infection with M. pneumoniae in patients with exanthem and pneumonia, although other etiologic possibilities should also be considered. ( info)
