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.

From 1967-1973, a total of 54 strains of Mycoplasma pneumoniae was isolated from patients suffering from different acute respiratory diseases, with an average positive isolation rate of 4.7%. Most mycoplasmas were isolated from patients aged 40-60, and with pneumonia of primary atypical pneumonias. The highest frequency of isolation was found in sputum collected 4-8 days after onset of illness. Colony formation on PPLO medium usually occurred 7-12 days after incubation. Serological tests were methods of choice for diagnosis of mycoplasmal pneumonia. In the 6 years period, 163 patients were diagnosed: 74 were positive only by metabolic inhibition test (MIT), 55 were positive only by cold agglutination test (CAT), and 34 gave positive by both tests. Of the above 2 tests, the CAT is nonspecific, but the MIT appears to be more sensitive and specific. Of the 94 sera positive by MIT, 42 (48.2%) were also positive by CAT; of those negative by MIT, 45 of 507 (8.8%) were positive by CAT. Of 45 sera with positive mycoplasma isolation, 37 (82.2%) were also positive by MIT, but only 22 (48.9%) showed the rises of CAT titers. Clinical features of mycoplasmal pneumonia were almost similar to those described by the other investigators. The chief symptoms were fever, coughs, chills, rales, malaise, sore throat headache and chest pain. The sedimentation rate of erythrocytes was accelerated. White count was normal in most cases. Both leucocytosis and leucopenia were found in 10% of the cases. Seasonal variation in incidence of mycoplasmal pneumonia was not obvious, however the lowest incidence occurred during summer. A roentgenogram of the chest was necessary for diagnosis of mycoplasmal pneumonia, and the lung infiltration was mainly located on right side (57.1%), segmentally, and limited to one lobe, especially the lower lobe.

From 1982 to 1991, we experienced 76 patients with Mycoplasma pneumoniae pneumonia which were confirmed by serologic tests. There were 32 (42%) male and 44 (58%) female patients. One patient had underlying disease of diabetes mellitus while the other patients were in good health. The age ranged from 9 months old to 72 years old. All the patients complained of fever and coughing; 63% had dry cough and 37% had sputum production. Upper respiratory tract complaints such as rhinorrhea, sore throat, or earache were noted in 57% of the patients. Fifty-five percent of the patients had GI symptoms of anorexia, nausea, vomiting, or diarrhea. Other complaints included myalgia/arthralgia (29%), headache (30%), and general malaise (32%). Dyspnea (17%) and chest pain (20%) were occasional complaints. Seventy-one percent of the patients had WBC counts < 10000/cu mm and 29% > 10000/cu mm. The mean value of C-reactive protein (CRP) was 53.1 micrograms/ml, while 16% of the patients had a CRP value above 100 micrograms/ml. Thirty-one percent of the patients were noted to have a transient elevation of serum transaminase. Four different patterns of infiltration were seen in chest radiographic manifestation: 1) peribronchial and perivascular interstitial infiltrates (18.4%), 2) nonhomogeneous patchy consolidations (22.4%), 3) homogeneous acinar consolidations (27.6%), and 4) mixed interstitial and alveolar infiltrates (27.6%). Interstitial infiltration was more commonly seen in pediatric than adult patients (46% vs 20%). Other features of the radiologic manifestation were as follows: unilateral lesions in 80% of patients, single lobe lesions in 77%, lower lobe predominant in 69%, pleural effusion in 7%, and radiographic deterioration in 10%. Mycoplasmal pneumonia should be considered in the differential diagnosis of community-acquired pneumonias.

A 61-year-old man presented with dyspnoea, chest pain, high fever and rigour. Chest X-ray revealed a combination of alveolar consolidations and abnormal nodular and interstitial markings. His clinical condition deteriorated despite treatment with antibiotics prescribed on a working diagnosis of pneumonia with an atypical pathogen. Finally, an open-lung biopsy specimen showed the characteristic picture of bronchocentric granulomatosis. Serological testing supported a primary infection with Mycoplasma pneumoniae. The patient responded well to treatment with prednisolone and erythromycin and five months after discharge, no radiological abnormalities were found. The combination of bronchocentric granulomatosis and mycoplasmal pneumonia has never been described in the literature and a causal relation can only be suggested. This case-report illustrates the importance of invasive diagnostic procedures if a patient with a clinical pneumonia fails to respond to adequate treatment.

The aim of this study was to analyze the clinical spectrum and seek potential curable causes of spontaneous pneumomediastinum (SPM) in children in order to minimize respiratory morbidity. Medical records from 1986 to 2003 were retrospectively reviewed at a tertiary pediatric facility in northern Taiwan. Sixteen cases of SPM were identified. There were eleven boys and five girls (M:F = 2.2:1) and ages ranged from 2 to 17 years (average, 10 years). Cough (81%), dyspnea (75%) and chest pain (56%) were the predominant symptoms and expiratory wheezing (63%) and neck crepitus (50%) were the most common physical findings. The specific sign of Hamman's crunch was noted in only one child initially. A coughing-related Valsalva maneuver (13 patients/81%) was the most common cause of pneumomediastinum in these children. The most common underlying medical causes were asthma (8 patients/50%) and idiopathic origin (5 patients/31%). Acute gastroenteritis, foreign body aspiration and mycoplasmal pneumonia were each found in one patient respectively. All patients had subcutaneous emphysema on initial chest radiographs. Two patients were complicated by pneumothorax and required intensive respiratory therapy. The average hospital stay was 4 days (range 1-9 days). Rapid resolution of symptoms without long-term sequelae was common except for one patient who had hypoxic-ischemic encephalopathy with epilepsy after foreign body removal. We conclude that in young teenagers, who suffer from cough, dyspnea, chest pain and associated discomfort of throat or neck, the diagnosis of SPM should be considered and chest radiography including posterior-anterior and lateral projections should be performed to verify the diagnosis. Because of the high prevalence of asthma related SPM, children of idiopathic SPM should undergo diagnostic pulmonary function tests after the acute episode, to establish whether the child has asthma. Targeted investigations of the underlying causes of SPM might decrease respiratory morbidity and avoid further complications.

Mycoplasma pneumoniae is a common pathogen for respiratory infection in children, and vascular complication is one of the rarest extrapulmonary complications but with serious consequences. We report a twelve-year-old Chinese female presenting with fever, dry cough, and chest pain aggravated by respiration. She was diagnosed pneumonia due to Mycoplasma pneumoniae and treated with Azithromycin until unexpected tachypnea and swelling in the right lower limb happened. Then ultrasonic examination had revealed two separated thrombi in deep veins before pulmonary embolism was found. Finally she was cured by anticoagulation and immunosuppressive therapy. Though the mechanism of thrombosis after Mycoplasma pneumoniae infection remains unknown, the positive finding in anticardiolipin antibody as well as multi-site thromboses gives a strong hint to immune modulation. Thrombosis should be considered for those who have significantly increased C-reactive protein and positive anticardiolipin antibody after Mycoplasma pneumoniae infection. To our knowledge, this is the first report describing two unattached thrombi in deep veins associated with pulmonary embolism after Mycoplasma pneumonia infection.

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia-related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain. He was found to have right-side loculated complicated parapneumonic effusion and underwent drainage with a pleural catheter followed by fibrinolytic therapy. He was then found to have new-onset systemic lupus erythematosus concomitant with Mycoplasma pneumonia, leading to lupus flare and lupus nephritis. He responded well to levofloxacin, steroids, hydroxychloroquine, and mycophenolate, with complete resolution of loculated pleural effusion and symptom improvement. Our case describes the rare combination of Mycoplasma pneumoniae pneumonia, parapneumonic pleural effusion, and lupus flare with lupus nephritis. Early identification and treatment can lead to better out come in young patients.
