In this article is described problems of bronchioloalveolar carcinoma, with respect to increased incidence of adenocarcinoma and bronchioloalveolar carcinoma. It was observed that bronchioloalveolar carcinoma occurs more frequently in younger persons and in women. Etiology of bronchioloalveolar carcinoma is still unknown. There is not an obvious connection with smoking but connection with previous damage of lung parenchyma. Bronchioloalveolar carcinoma can be defined as neoplasm which is not of central origin , but is peripherally located; therefore the term "bronchiolo-" but not "broncho-alveolar" carcinoma. It grows along alveolar septa and lung parenchyma remains intact. There is three pathohistological subtypes of bronchioloalveolar carcinoma: mucinous, non-mucinous and sclerotic form and three radiological patterns: solitar, pneumonia-like and diffuse. Clinical features depend of the stage and patient are most frequently asymptomatic. They later present with chest pain, dyspnea, cough, hemoptysis and weight loss. Complications include bronchorrhoea and intrapulmonal shunts. These findings, together with laboratory analysis, radiological tests (including CT scans) and cytological or hystological proof of malignancy, make definite diagnosis. Therapy depends on the stage of disease and is identical with that of other subtypes of non-small-cell lung cancer.

In April 1992 an outbreak of severe respiratory illness occurred among aerographic textile workers in the area of Alcoi, Autonomous Community of Valencia, Spain. An epidemiological study linked this outbreak to the use of a reformulated aerosolized product, Acramin-FWN. We analyzed clinical, laboratory, and pathological data of the first 14 patients with confirmed organizing pneumonia (OP) secondary to this newly recognized occupational toxicant. The mean age of the patients was 30 yrs. The most common clinical findings were cough (86%), epistaxis (71%), dyspnoea (64%), oppressive chest pain (57%), and crackles (50%). A restrictive functional pattern was evident in 64%. Radiographic findings consisted predominantly of patchy infiltrates in 65% and a micronodular pattern in 35%. Treatment with corticosteroids did not prevent initial progression in 11 of the 14 patients and development of irreversible respiratory failure in five patients. At necropsy, besides features of OP, interstitial fibrosis and diffuse alveolar damage were evident. A low total lung capacity, the presence of crackles at admission, and increases in the alveolar-arterial oxygen difference were predictive of death. The organizing pneumonia caused by the inhalation of Acramin-FWN is characterized by a tendency to evolve into progressive interstitial fibrosis despite the use of corticosteroids. The illness is restricted to the respiratory system and once respiratory failure has developed the prognosis is poor.

During the 7 years from 1990, thirty-two patients (20 in male and 12 in female, mean age; 53 years old) were diagnosed as having pulmonary cryptococcosis. To clarify the essential points for early diagnosis of pulmonary cryptococcosis, we reviewed the clinical records and chest images. Three patients had a past history of pulmonary tuberculosis and eleven patients had underlying disorders such as malignancy, chronic pulmonary diseases and so on, but no HIV infection, which would affect this disease. Eighteen patients did not have any past history nor complications. The symptoms such as cough, sputum, chest pain and fever were generally of low-grade, 14 patients had no symptom at diagnosis. Except of some patients with severe infections and severe underlying disorders, laboratory findings such as inflamatory and nutritious markers were almost within near the normal range. On plain chest X-ray films the distribution of lesions was almost in proprtion to the volume of the lobes. The multifocal nudular and/or infitrative shadows wer observed in about 2/3 cases and single lesion in about 1/3. The width of lesions were minimal except of one case with interstitial pneumonia and two cases with multifocal segmental pneumonia. The cavity lesions were observed in 7 cases and hilar lymphadenopathy in 3 cases. On CT images, the lesions were almost located in the outer zone, the lesions which were adjacent to the pleura were observed in 15 cases. Cavitary lesions were almost smooth in edge and ubiquitous, the walls were also thick. The peripheral air-bronchogram in the nodular/infitrative shadows were observed in three cases. Pulmonary cryptococcosis is air-borne and almost a chronic infection except in AIDS patients, so careful planning for examination is essential with considerations of the characteristics of clinical and imaging features of this infection.

In the present report we describe 4 previously healthy women who developed cryptococcal pneumonia during pregnancy, and 1 pregnant woman with cryptococcal meningitis. These cases illustrate a previously uncharacterized spectrum of cryptococcal disease. We also discuss 24 patients previously reported who had cryptococcal meningitis during pregnancy. Finally, we review the available data for each therapeutic option and present an algorithm for management based on appraisals of disease severity and risk to the unborn fetus. This report emphasizes the need for heightened awareness of cryptococcosis in the differential diagnosis of pneumonia, chest pain, and hypoxemia in the pregnant patient, but at present, there are insufficient epidemiologic data to determine whether incidences of pulmonary or disseminated cryptococcosis actually increase during pregnancy. The risk of congenital cryptococcosis to the unborn fetus is low, and the most likely mechanism whereby neonates acquire invasive fungal pulmonary infection is through aspiration. While it is unclear whether there is any real increased risk of spontaneous abortion or premature labor, the data indicate that overall fetal outcome depends on effective treatment of maternal infection. For patients with dense air-space consolidation, progressive pulmonary disease, or dissemination, antifungal therapy is necessary. Optimal treatment is determined by the acuity and severity of the clinical presentation. Amphotericin B (approximately 1 g) with or without flucytosine represents the choice for initial treatment of the more acutely ill patient with disseminated or progressive pulmonary cryptococcosis who requires hospitalization (whether during or after pregnancy). Oral fluconazole appears to be safe and effective alternative therapy after delivery for the less severely ill patient who can be managed on an outpatient basis. While the use of fluconazole during pregnancy generally appears safe in terms of fetal outcome (49, 58), the class C status and single report of fetal malformation (62) preclude confident recommendation for its use during pregnancy. The risks and benefits of this effective and generally less toxic drug should be discussed with the parents and weighed against the use of amphotericin B. For pregnant women with limited pulmonary cryptococcosis (segmental or nodular infiltrates) and no evidence of dissemination, we recommend close follow-up without antifungal therapy similar to the recommendation for normal hosts with minimal disease. However, it is important to note that there is no extensive experience upon which to base this recommendation for pregnant individuals (45, 55, 103, 108). It is prudent to use frequent physical examinations (for example, every 1-2 months), combined with chest roentgenograms and serum cryptococcal antigens to monitor progression and/or development of disease in both the mother and child for approximately 6 months postpartum. In conclusion, cryptococcosis during pregnancy presents a special challenge to the clinician. A balanced therapeutic approach holds great promise for successful maternal and fetal outcomes.

The present retrospective study was undertaken to study the clinical profile of primary bronchogenic carcinoma seen during last eight years in a teaching hospital. Out of a total of 279 diagnosed cases, 86% were males with an average age of 57 years, smoking was the risk factor in 81.6%. Forty percent of female patients were smoker with a significant overlap in use of smoking objects. Twenty four (8.8%) patients were less than 40 years of age at the time of diagnosis. Average duration of illness was 4.5 months. Weight loss (77%) and fever (34%) were the commonest general symptoms. Other chest symptoms include cough (68%), dyspnoea (59%), chest pain (22%), hemoptysis (20%) and dysphagia (6%). Fiberoptic bronchoscopy (FOB) (75%) and fine needle aspiration cytology (FNAC) (74.8%) were found to be the most efficient diagnostic procedures. Histologically, squamous cell carcinoma, adenocarcinoma, large cell carcinoma and small cell carcinoma were seen in 42%, 20%, 18% and 14% cases, respectively. Six percent patients showed malignant cells only and marked as unclassified. Radiologically, obstructive pneumonitis was the commonest presentation (59.5%) followed by mass lesion (31.8%) and rib destruction (5.1%). Inspite of its limitation, this study for the first time reports lung cancer pattern from mid-west Rajasthan.

Psittacosis, also referred to as ornithosis, is a disease primarily of birds, which may be transmitted to humans. Psittacosis is caused by Chlamydia psittaci, an obligate intracellular parasite found worldwide. Humans are infected with C. psittaci when the organism enters the blood stream, usually through inhalation of dried excrement from diseased birds or through wound contamination with infected avian secretions. C. psittaci replicates in the liver and spleen and infects the lung and other organs hematogenously.1 The clinical manifestations of human psittacosis range from a mild respiratory infection to a severe systemic illness.1,2 Symptoms are frequently described as flu-like with fever, headache, body aches, and dry or productive cough. Sore throat, chest pain, abdominal pain, vomiting, and diarrhea are variably present. Physical findings may include a pulse-temperature dissociation, localized lung crackles, hepatomegaly, splenomegaly, and a pale macular skin rash. Chest radiographs may demonstrate lesions that are atelectatic, patchy, miliary, nodular, or consolidated in one or both lungs. White cell counts, erythrocyte sedimentation rates, and liver function tests are usually normal. In severe illness, signs and symptoms of liver dysfunction, neurological impairment, and respiratory and renal failure may be present. Since 1879 when psittacosis was recognized as a disease entity, cases have been reported in North and South America, Europe, Asia, and Australia. However, reports of psittacosis in Africa have been rare. An Ethiopian group, studying community-acquired pneumonia, published what they claimed to be the first report of psittacosis in Africa in 1994.3 The report published here is believed to be the first documented case of human psittacosis in Egypt.

A 37-year-old woman was taken to a hospital because of sudden chest pain. She lapsed into shock, and the ECG indicated acute myocardial infarction. The ECG later showed ventricular fibrillation, and the patient was given cardiac massage while being transported to our hospital, where she was resuscitated with a percutaneous cardiopulmonary support system. Emergency coronary angiography revealed 99% stenosis of the left main coronary artery. PTCA was performed, and the stenotic lesion was released, but dissection and rapid formation of a thrombus were detected in the LAD. Re-PTCA was performed, but the hemodynamics did not improve, and emergency CABG of the LAD, D1, and LCx was performed. Postoperative max CPK was 18,957 IU/L. Although postoperative MRSA pneumonia developed as a complication, weaning from the respirator was performed 17 days after the operation. The patient was discharged, ambulatory, 74 days after the operation.

Invasive pulmonary aspergillosis is an opportunistic infection occurring in a background of severe immune depression. The majority of cases occur in patients who have malignant hematologic disease, particularly during chemotherapy induction or consolidations phases for acute non-lymphocytic leukemia. The principal risk factors are profound (PN < 500 per mm3) and prolonged (very high risk beyond 20 days) neutropenia, perturbed phagocyte function and cellular immune deficiency (AIDS, immunosuppressive treatment in organ and bone marrow recipients). Clinically, invasive pulmonary aspergillosis presents as acute non-specific pneumonia with cough, chest pain and fever. The severe infection rapidly becomes life-threatening. The development of massive hemoptysis is a major risk. We report four cases of invasive pulmonary aspergillosis in patients who had hemoptysis. All four patients developed non-specific pneumonia resistant to broad-spectrum antibiotics during post-chemotherapy aplasia. Computed tomography of the thorax and bronchoscopy with bronchoalveolar lavage was performed due to the occurrence of hemoptysis. In the first two cases, the patients were recovering from aplasia. The thoracic CT scan showed evidence of a cavitating mass with peripheral vessels. Bronchoscopy findings suggested mucosal lesions. The patients were managed surgically. Pathology confirmed the diagnosis of invasive pulmonary aspergillosis with the presence of ischemic necrosis of the pulmonary parenchyma harboring numerous aspergillus filaments. Outcome was favorable and chemotherapy was re-initiated in one case. These two patient died from their hematological disease a few months later. The other two patients remained in aplasia. A CT of the thorax showed multifocal infiltration with vascular contact. Bronchoscopy was again suggestive. One patient developed massive hemoptysis with respiratory distress. Embolization was performed but the patient died two days after onset of hemoptysis. In the last case, embolization was successful and outcome was favorable enabling a bone marrow allograft; the patient died a few months later from the hematological disease. The potential gravity of hemoptysis in the course of invasive pulmonary aspergillosis should lead to early treatment with emergency CT scan and, if possible, bronchoscopy with bronchoalveolar lavage to establish the therapeutic strategy based on surgical excision or embolization of the pulmonary or bronchial arteries.

A 40-year-old female was admitted with right chest pain. SLE was absent from her past history, although she complained of polyarthralgia in winter. Atypical pneumonia/pleuritis was suspected by chest X-ray film, showing a nodular shadow in the right lower field and moderate pleural effusion. Chlamydia pneumonia was diagnosed by elevated anti-C. psittsci antibody, while characteristics of pleural fluid revealed serositis accompanied by SLE because of the high titered anti-DNA antibody and the low titered complement. She was cured by clarithromycin and subsequent administration of prednisolone and cyclophosphamide.

Carcinoids are neuroendocrine neoplasms. Bronchial carcinoids are unusual, malignant primary neoplasms that characteristically involve the central airways and typically exhibit well-defined margins and bronchial-related growth. Bronchial carcinoids include low-grade typical carcinoids and the more aggressive atypical carcinoids. These tumors usually affect patients in the 3rd through 7th decades of life who are often symptomatic with cough, hemoptysis, or obstructive pneumonia. Bronchial carcinoids radiologically manifest as hilar or perihilar masses, with or without associated atelectasis, pneumonia, bronchiectasis, or mucoid impaction. At computed tomography, an anatomic relationship of these tumors to a bronchus is usually seen, and they may show contrast material enhancement or calcification. In rare cases, carcinoids occur in the thymus; when they do, they are aggressive tumors that affect adults who usually present with chest pain, cough, and dyspnea. Thymic carcinoids manifest radiologically as anterior mediastinal masses and may mimic thymomas. Thoracic carcinoids are treated by surgical excision. The prognosis for patients with typical bronchial carcinoids is excellent; patients with atypical bronchial or thymic carcinoids have a worse prognosis.
