Salmonella infections are widespread particularly in tropical zones. Each year, 12.5 million cases of typhoid fever are reported with an incidence of 540 cases for every 100,000 inhabitants in developing countries versus 0.2 cases in industrialized countries. Pleuropulmonary manifestations constitute the most common extra-intestinal manifestation of salmonella infection. Counts are usually carried out in the digestive tract. Respiratory tract manifestations result from blood-borne diffusion from mesenteric lymph nodes, but gastroenteritis goes unnoticed in 2 of 3 cases. Predisposing factors are frequent including cancer, previous graft placement and immunosuppressant therapy, sickle cell disease, alcohol abuse, and pre-existing pulmonary disease. Clinical manifestations are usually acute but subacute forms cannot be ruled out. Cough is a common symptom observed in 25% of patients with typhoid fever. Pneumonia is uncommon overall (1%) but occurs in 50% of patients with pleural effusion, empyema, lung abscess, or bronchopleural fistula. A few cases of adult respiratory distress syndrome have been described in the literature. Recognition is important since these manifestations may signal previously unsuspected underlying pulmonary disease. Treatment requires appropriate antimicrobial therapy and close surveillance to prevent recurrence or complications.

Bronchopulmonary infections caused by trichomonads have been reported mainly in patients with pre-existing pulmonary or debilitating disease (e.g. bronchial carcinoma, lung abscess, bronchiectasis). Pulmonary trichomoniasis is most often due to infection with Trichomonas tenax, usually regarded as a harmless commensal of the human mouth, and may rarely be caused by other trichomonas species. A 45 year old female presented with a dry cough, exertional dyspnoea and malaise. These symptoms persisted for 6 months regardless of anti-inflammatory and anti-obstructive inhalative therapy. Sarcoidosis of the lungs, diagnosed 20 years prior, had been asymptomatic since and there was no coexistent disease. Laboratory data revealed increased ACE-levels (90 IE/ml) and lung function showed bronchial hyperreactivity on histamine challenge. No other abnormalities were found (chest x-ray, bronchoscopy, lung function test, blood count and serum calcium). The diagnosis was based on the cytological identification of numerous trophozoites of T. tenax in the bronchoalveolar lavage. Therapy with oral metronidazol for 40 days led to complete recovery from symptoms and normalisation of ACE serum levels. The patient has remained well for 12 months since. The pathogenicity of oral trichomonads in the non-immunocompromised host remains uncertain. Our patient had no known medical risk factors by comparison with published cases. The case illustrates the clinical relevance of pulmonary trichomoniasis in an otherwise healthy person.

A 51-year-old female was admitted to Nagano Matsushiro General Hospital because of fever, cough and dyspnea on exertion. Her laboratory data revealed leukocytosis with hypereosinophilia, a high erythrocyte sedimentation rate and c-reactive protein. Chest radiography revealed an infiltration shadow with a cavity in the right upper lobe. A lung abscess was diagnosed and antibiotics were administered. Laboratory results showed improvement, but chest radiography continued to show cavities. She was admitted to our hospital because of fever, left pleural effusion and progression of cavities on chest radiographs. She showed no abnormalities of the upper airway or kidney, and was negative for c-antineutrophil cytoplasmic antibody (c-ANCA). Because a positive c-ANCA was seen on day 8 of hospitalization, L-type limited Wegener granulomatosis (WG) was diagnosed according to Gross et al. Prednisolone (PSL) was administered, which improved the anemia, eosinophilia and the cavities. On day 7 of PSL administration, of the left pneumothorax occurred as a complication caused by perforation of the left chest cavity, but her clinical course was good after a cavernectomy was performed. Some studies have reported that limited WG shows a negative c-ANCA, and that antibiotic therapy improves inflammation. The L-type of limited WG revealed a low-grade positive ratio and titer of c-ANCA. Moreover, L-type limited WG responds well to therapy. We therefore selected PSL administration only against L-type limited WG. We have reported L-type limited WG with eosinophilia and the negative effects of c-ANCA at an early clinical stage.

Two cases of varied forms of Aspergillosis are reported who were being diagnosed and treated on different lines. One case, who was treated on lines of allergic bronchitis, had very high total eosinophil count and, fleeting pulmonary infiltrates over a period of 5 years along with history of cough, fever and weight loss. Aspergillus fumigatus was grown on sputum culture. On the background of a long standing history of bronchial asthma with evidence of peripheral as well as central eosinophilia, fleeting pulmonary infiltrates and A. fumigatus grown on sputum culture, we kept the diagnosis of Allergic Bronchopulmonary aspergillosis (ABPA) and put the patient on steroids and Itraconazole. Patient showed good response to therapy. Another case, a 50 year old male, presented to us with clinical picture of subacute myelitis. Being a known case of ABPA and on steroid therapy for long duration, we kept the diagnosis of invasive aspergillosis. Growth of Aspergillus fumigatus on sputum culture on three occasions and MR imaging of spine further supported our view. Aspergillosis of the lung do not have characteristic clinico-radiological features of permit the diagnosis and should be considered in the differential diagnosis of tuberculosis, pneumonia, bronchiectasis, lung abscess and bronchial asthma.

A patient with end-stage renal disease due to human immunodeficiency-associated nephropathy developed fever, cough and chest pain over a week's duration. He was diagnosed with lung abscess and started on antibiotic coverage. He underwent bronchoscopy because of progression of his illness and persistent fever and bronchoalveolar lavage culture isolated Legionella micdadei. In spite of appropriate antibiotic therapy, the patient remained febrile for 10 days, necessitating chest tube drainage. After a 6-week course of antibiotics and drainage, the patient made an uneventful recovery. Infections due to L. micdadei may be hard to diagnose because of difficulties in isolating this bacteria.

This prospective study represents our experiences in using fibreoptic bronchoscopy (FOB) in the evaluation of different thoracic lesions. Over a 20-month period, 203 patients (151 males and 52 females) (age range: 15-100 years) underwent bronchoscopies. The patients had a wide range of symptoms and/or radiographic abnormalities. The majority had cough and shortness of breath; haemoptysis was a common symptom. In all, 148 patients had neoplasms and 55 had non-neoplastic lesions. The most common malignancy was bronchogenic carcinoma (91 confirmed, 33 suspected). Other neoplasms included pulmonary metastases and mediastinal tumours. The non-neoplastic chest lesions included pulmonary tuberculosis, pulmonary hydatid cyst, lung abscess and resolving chest infection and chronic bronchitis. FOB was most useful in the diagnosis of bronchogenic carcinoma (positive diagnostic yield of 73%). It was least useful in diagnosing mediastinal tumours.

The incidence of Rhodococcus equi infection in solid-organ transplant recipients continues to rise throughout the world. Unfortunately, this opportunistic pathogen is still underestimated and potentially disregarded by physicians and microbiology laboratories due to its morphology on Gram staining. Pulmonary involvement is the most common finding in the immunocompromised host. We report a case of a 63-year-old heart-transplant recipient who presented with increasing fatigue and nonproductive cough for 3 weeks. After full evaluation, a lung abscess was demonstrated by thoracic computerized tomography (CT). Blood and sputum cultures were remarkable for heavy "diphtheroids." Although the Gram-stain result was initially interpreted as a contaminant, a clinical suspicion for Rhodococcus assisted in further investigation. Broncheoalveolar lavage and CT-guided biopsy of the lung abscess revealed heavy growth of diphtheroids. However, further evaluation by a reference laboratory demonstrated mycolic acid staining consistent with R. equi. Surgical drainage and prolonged antibiotic therapy resulted in complete remission of the pneumonia and abscess. This represents the fourth reported case of R. equi infection in a heart transplant recipient. It is imperative that all physicians and laboratory staff consider R. equi when an immunocompromised patient has any type of pneumonia, especially with abscess formation.

The prevalence of bronchiectasis decreased due to the effective use of vaccines and advances of antibiotic therapy after 1970. However, it remains an important long-term morbidity of lower respiratory tract infection in developing country. To evaluate the clinical features of bronchiectasis in a tertiary hospital, we collected 21 patients with a diagnosis of bronchiectasis in Taipei Veterans General Hospital from May, 1984 to Dec, 2001 in pediatric outpatient with the admission of age below 18 years old. The diagnosis was based on the history of recurrent cough with fetid sputum, hemoptysis, or recurrent lobar pneumonia for months at least and radiological findings of lobar infiltration, tram-track like patterns, bronchiolar dilatation or honeycomb patterns. The diagnostic examinations included chest plain radiography, bronchography and chest computed tomography (CT) scans. Respiratory tract infections were the commonest cause predisposing to bronchiectasis in our study. Tuberculosis is not rare in this study. In recent years, immunodeficiency disorders have been recognized. Most patients suffered from recurrent cough and fetid sputum for years before diagnosis was established. Hemoptysis was the second common symptom in our study. The plain chest radiograph of bronchiectasis revealed dilatation of bronchial trees with honeycomb pattern or infiltration only. In recent years, chest CT became the most accurate and being noninvasive diagnostic tool. The initial treatment was primarily medical conservative therapy. Only five patients in our cases underwent pulmonary resection due to persistent hemoptysis, recurrent bacterial pneumonia or pulmonary parenchyma destruction. Most patients still suffered from recurrent pneumonia or occasional exacerbation in the long-term follow-up. In conclusion, bronchiectasis is not uncommon in pediatric population in northern Taiwan. The history of recurrent cough with fetid sputum, hemoptysis, or recurrent pneumonia were the most important clues to early diagnosis of this disease. Early diagnosis and appropriate treatment are effective in order to prevent lung abscess, empyema and pneumothorax, bronchopleural fistula, hemoptysis or cor pulmonale.

Foregut cysts frequently cause symptoms in the first three decades of life. The symptoms consist of dyspnea, wheezing, cough and sputum, dysphagia, stridor, and those associated with right heart strain. Symptoms and the radiological appearance of the uncomplicated cyst mimic mediastinal tumour and mediastinal obstruction. The symptoms and radiological appearance of the ruptured infected cyst simulate those of lung abscess, diaphragmatic hernia, ruptured hydatid cyst, cavitated peripheral carcinoma and pulmonary tuberculosis. In this series the differentiation from other cysts was made thus: with intralobar sequestration, a systemic arterial blood supply was demonstrated; with hydatid cyst, there was a positive intradermal skin test and (radiologically) following rupture, the appearance of a pericystic pneumatocele followed by the water-lily sign was diagnostic; with emphysematous cysts, the signs of associated bronchitis were present; in the presence of pseudocysts, there was a previous history of lung abscess, staphylococcal infection or tuberculosis. Cysts should be removed when first diagnosed.

A 53-year-old man visited his family doctor complaining of chest pain and cough in January 2006. He had a 5-year history of uncontrolled diabetes mellitus. His illness was diagnosed as pneumonia of the left lingular division. Antibiotics were started but his pneumonia worsened repeatedly after insufficient antibiotics due to his poor compliance with medication. In addition to pneumonia, he began to have hemoptysis at the end of May and was admitted to our hospital. Contrast-enhanced CT scan on admission showed a lung abscess on the left lingular division and formation of a pulmonary pseudoaneurysm inside the abscess. Treatment with SBT/ABPC rapidly improved his condition but massive hemoptysis recurred 9 days after admission. Embolization of the bronchial artery and pulmonary pseudoaneurysm successfully controlled airway bleeding. When hemoptysis occurs due to sustained inflammation such as a lung abscess, bleeding from the pulmonary artery should be considered and a precise evaluation including contrast-enhanced CT and pulmonary angiography made.
