In the Iraq-Iran war (1981-1989), extensive use of chemical weapons such as mustard gas caused high mortality, morbidity, injuries, and chronic side effects in vital organs, especially the respiratory tract. This study was performed to evaluate the long-term effects on respiratory tract of victims. Two hundred and twenty victims were referred from the Mostazafan and Janbazan Foundation of Babol from 1994 to 1998. Complete histories, physical examinations, chest X-rays, and PFTs were performed. Nearly all the victims complained of cough, dyspnea, and suffocation. Hemoptysis was found in 6 victims. In 4 patients, respiratory distress with use of accessory muscles was observed. Two-thirds of the subjects had wheezing and coarse rale. For the other third, physical examination revealed no abnormal finding. Radiographic findings were mostly normal. Spirometry revealed an obstructive pattern in all patients and PFT revealed mostly normal and restrictive patterns. The shortlist time from exposure to study was 7 years and the longest was 13 years. Most patients reported mustard gas exposure and a few of them did not know what type of gas exposure they had. The clinical evaluations, radiography, and PFTs revealed that the most prevalent effects of chemical weapons on respiratory tract were chronic obstructive lung disease, presenting as many types of obstructive involvement.

Pulmonary carcinoid tumors are neuroendocrine malignant tumors that make up 1% to 2% of all lung tumors. According to histopathologic criteria, carcinoids can be divided into typical (TC) and atypical (AC) carcinoids. Carcinoids can be placed in a spectrum of neuroendocrine tumors, ranging from low-grade malignant TC to intermediate AC to high-grade large-cell neuroendocrine carcinoma and small-cell lung carcinoma. Familial pulmonary carcinoids are rare. The most common symptoms are hemoptysis, cough, recurrent pulmonary infection, fever, chest discomfort and chest pain, unilateral wheezing, and shortness of breath. Paraneoplastic syndromes are rare and include carcinoid syndrome, Cushing's syndrome, and ectopic growth hormone-releasing hormone secretion. The diagnosis is usually established by flexible bronchoscopy and biopsy, although occasionally this can result in severe hemorrhage. Immunoscintigraphy by somatostatin analogs can also be useful in diagnosis. The treatment of choice is surgical resection, and prognosis is relatively good in TC, although it is worse in AC. The role of radiotherapy and chemotherapy as part of multimodality treatment or palliation is still debated.

OBJECTIVE: To alert pediatricians about the possibillity of childhood Idiopathic Pulmonary Hemosiderosis, in cases of anemia associated with chronic lung disease. METHODS: This article documents a case of Idiopathic Pulmonary Hemosiderosis in a 6 year-old child, with histopathological documentation, and reviews it against published literature. RESULTS: A 6 year-old child with history of anemia and lung disease characterized by wheezing, recurrent pneumonia and digital clubbing was admitted to the hospital for investigation, where he suffered sudden respiratory failure and hemoptysis.He was submitted to a lung biopsy which showed a histopathological diagnosis compatible with pulmonary hemosiderosis. Therapy with high doses of corticosteroids was initiated with a good early response. After two and a half months of therapy he had a new bleeding episode, culminating in death. CONCLUSIONS: Idiopathic Pulmonary Hemosiderosis should be included as a possible diagnosis of children with anemia and chronic lung disease. This case is a good example.

1. Epidemiological trend of TB and its diagnosis among the elderly: Masako OHMORI (Research Institute of Tuberculosis, JATA). It is estimated that over 10,000 TB patients will occur among the elderly aged over 75 years of age during 2010 and 2020. Though the new TB patients among the elderly over 65 years of age decreased in number from 1987 to 2001, sputum smear positive patients, which are highly infectious increased by 1.3 times for the same age group, and 2.3 times for that of over 80 years of age. 17.6% of those elderly patients were detected in institutions, either hospitals or nursing homes. These indicate that the elderly will become higher risk of TB for causing early death and infection to others during their admission in the hospitals or nursing homes. 2. Clinical characteristics of TB among the elderly: Nobuhiko NAGATA (Department of Internal Medicine, National Ohmuta Hospital). Analysis of the 93 elderly TB patients shows that TB diagnosis was delayed among the elderly. For TB diagnosis, 43.2% took over 1 month, and 27.3% over 2 months among the patients over 75 years of age, compared to 22.9% and 9.7% respectively for the patients under 65 years. The prognosis was also poor. Of all who died in the hospital during TB treatment, 40.9% (mostly complicated with other diseases) was among the elderly over 75 years, while it was 6.5% among those under 65 years. Complication of dementia delayed the diagnosis. 79.4% of the smear positive patients over 75 years were diagnosed while admitted in a general ward, and 40% had been admitted 2 weeks or more before diagnosis. 3. Use of serological tests for the diagnosis of TB among the elderly: Atsuyuki KURASHIMA (Department of Clinical Research, National Tokyo Hospital). As TB diagnosis is difficult for the elderly due to non-specific appearances of signs/symptoms, X-ray shadows or negative tuberculin reaction, some serological tests, which have been recently developed, can be useful as a supplementary diagnostic tool. One of them is anti-lipoarabinomannan antibody. 74.3% was positive to this among 148 bacteriologically confirmed TB cases; 77.8% for those aged 65 years and above, and 71.1% for those under 65 years. To anti TBGL antibody, 78% of 170 confirmed TB cases were positive; 75% for those aged 65 years and above, 79.8% for those less than 65 years. Multi-lipo antibody developed by Japan BCG Laboratory showed higher sensitivity of 91.5%. GPL-core antibody may increase the sensitivity. 4. Mode of TB detection in nursing homes: Shinji SHISHIDO (Research Institute of Tuberculosis, JATA). 15 elderly TB patients who had been diagnosed in 23 nursing homes in the last 5 years were analyzed. The average age was 80.7 years. 10 were male and 5 were female. 11 were sputum smear positive. The symptoms were fever (8), cough (7), wheezing (2), hemoptysis (1), chest pain (1), body weight loss (1), appetite loss (1). Number of patients by time durations before consulting a doctor of within 2 weeks, 2 weeks to 1 month, 1 to 2 months, 2 to 3 months, 3 to 6 months, and more than 6 months were 6, 1, 1, 3, 2, 2 respectively. The prognosis: 4 died within 10 days after diagnosis, 4 needed examinations for the symptoms but were delayed in diagnosis as they were not admitted due to dementia or disability. The orientation and training to the staff of the nursing homes are needed for early TB diagnosis. 5. Programme for the early detection of TB among the elderly: Tadayuki AHIKO (Murayama Public Health Center, Yamagata Prefecture). Based on the analysis of 138 confirmed TB cases registered in Yamagata Prefecture in 1998, services for early TB detection among the elderly should be 1) periodical chest X-ray examinations by the patients home doctors when underlying high risk diseases such as diabetes or cancer exist, and 2) -sputum examination for the symptomatic patients. A survey to 31 local governments conducting special TB services showed the special screening programme for the bedridden elderly in nursing homes was not so efficient due to low quality of the available X-ray facilities and low case detection rate. But these X-ray films can be utilized for comparison with those when any symptom arises.

The clinical characteristics most relevant to the decision to treat for a pulmonary exacerbation with antibiotics in cystic fibrosis patients were determined. Variables including age, increased cough frequency and sputum production, new crackles and wheezing, asthma, symptomatic sinusitis, hemoptysis, decreased lung function, weight loss, and new acquisition of Pseudomonas aeruginosa were collected in a large prospective multicenter database (Epidemiologic Study of Cystic Fibrosis). During a 12-month baseline period, data from 11692 patients were compared with data collected during the subsequent 6-month study period. Because pulmonary function assessments were unavailable for patients <6 years of age, separate analyses were done for those <6 and >or=6 years of age. The outcome of interest was any antibiotic treatment in the 6-month study period reported as indicated for an exacerbation. Characteristics with the most discriminatory power were determined using stepwise multiple logistic regression. For patients <6 years of age, the strongest independent associations with treatment for a pulmonary exacerbation were new crackles, increased cough frequency, decline in weight, and increased sputum production. For those patients >or=6 years of age, the strongest independent associations were a relative decrease in percent predicted forced expired volume in 1 sec, increased cough frequency, new crackles, and hemoptysis. The presence of three or more of these key characteristics was strongly associated with the occurrence of a treated exacerbation. The reproducibility of the model over time was confirmed by application to a subsequent set of data. This model has potential for use as an outcome measure in clinical trials, and to assist in treatment decisions for individual patients.

Tracheobronchial amyloidosis (TBA) is an uncommon localized form of amyloidosis with fewer than 150 reported cases in the literature. We report a case of primary diffuse tracheobronchial amyloidosis who presented with cough, wheezing, recurrent and progressive dyspnea as well as hemoptysis. Though there is no universally accepted treatment for the localized form, this patient was successfully treated with three sessions of bronchoscopic resection and adjuvant steroids. This report will review the various types of amyloidosis of the respiratory tract and their clinical features, in addition to discussing the different available treatment modalities for TBA.

Endobronchial tuberculosis (EBTB) is defined as tuberculous infection of the tracheobronchial tree. Common symptoms are cough, haemoptysis, sputum production, wheezing, chest pain and fever in active disease and dyspnoea and wheezing in the fibrous stage. This form of tuberculosis is difficult to diagnose because the lesion is not evident in the chest radiograph, frequently delaying treatment. Computed tomography is very useful in evaluating bronchial lesions such as stenosis or obstruction. The most important goal of treatment in active EBTB is eradication of tubercle bacilli. The second most important goal is prevention of bronchial stenosis. Corticosteroid therapy for the prevention of bronchial stenosis in EBTB remains controversial. However, the healing time of ulcerous lesions was shorter and bronchial stenosis was less severe, in patients treated with aerosol therapy, consisting of streptomycin 100 mg, a corticosteroid (dexamethasone 0.5 mg) and naphazoline 0.1 mg administered twice-daily along with conventional oral therapy. In inactive disease, treatment to restore full patency is appropriate. As steroids or other medications are unable to reverse stenosis from fibrous disease, airway patency must be restored mechanically by surgery or endobronchial intervention. Effectiveness and complications remain important issues with the mechanical techniques as use and evaluation continue. Corticosteroid therapy for prevention of bronchial stenosis in EBTB remains controversial. Our observations suggest that progression of bronchial stenosis can be prevented in patients who are treated with aerosol therapy with corticosteroids.

Endobronchial tuberculosis is defined as tuberculous infection of the tracheobronchial tree. Although clinical features differ between various types and stages of endobronchial tuberculosis, common symptoms are cough, hemoptysis, sputum production, wheezing, chest pain, fever and dyspnea. Endobronchial tuberculosis is difficult to diagnose, because the lesion is not evident in the chest radiograph. Computerized tomography is very useful in evaluating bronchial lesions such as stenosis or obstruction. The most important goal of treatment in active endobronchial tuberculosis is the eradication of tubercle bacilli. The second most important goal is prevention of bronchial stenosis. Corticosteroid therapy for prevention of bronchial stenosis in endobronchial tuberculosis remains controversial, but the best results are associated with minimal delay in the initiation of steroid treatment. In inactive disease, treatment to restore full patency is appropriate. As steroids or other medication are unable to reverse stenosis from fibrous disease, airway patency must be restored mechanically by surgery or endobronchial intervention. Aerosol therapy with streptomycin and corticosteroids is useful in treatment against active endobronchial tuberculosis. Time to healing of ulcerous lesions is shorter, and bronchial stenosis is less severe in patients on aerosol therapy. Progression to bronchial stenosis may be prevented if the therapy is initiated as soon as possible.

A 20-year-old male, presented with cough, haemoptysis, breathlessness and wheezing for the past one month. Contrast enhanced computerised tomographic (CECT), scan of chest and fibreoptic bronchoscopy revealed an endotracheal mass that on histopathological examination showed adenoid cystic carcinoma of trachea. Magnetic resonance imaging (MRI) scan of chest confirmed involvement of adjacent prevertebral, para-oesophageal and subcarinal lymph nodes rendering the tumour inoperable.

Tracheobronchopathia osteochondroplastica (TPO) is an uncommon benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. The nodules originate in the airway cartilages and thus typically spare the posterior membranous wall of the airways. The disorder is more common in men and the diagnosis is usually made in the fourth through sixth decades of life. There is no relationship to smoking or other systemic disorders. The disease is manifested by chronic cough and wheezing, which frequently lead to the mistaken diagnosis of asthma. Other pulmonary symptoms include dyspnea and hemoptysis. One of the complications is the increased incidence of recurrent respiratory infections. The pulmonary symptoms and complications are the consequence of narrowing and thickening of the airway walls. Even though roentgenologic imaging studies may indicate the diagnosis, bronchoscopy is the most definitive diagnostic test. The bronchoscopic appearance alone is diagnostic of the disease, and biopsy of the airway lesions is seldom, if ever, required. Although there is no specific therapy for this disorder, management of tracheobronchopathia osteochondroplastica includes bronchodilators, prompt treatment of pulmonary infections, and bronchoscopic dilatation when indicated.
