A syndrome of acute pulmonary edema has been previously reported among scuba divers in cold, European waters. Because of the temperatures involved, the name "cold-induced pulmonary edema" was coined in the original 1989 description. We report six individuals who developed the identical syndrome, five while diving in Puget Sound and one in the Gulf of Mexico. The four women and two men ranged in age from 24 to 60 yr. They experienced one to six episodes apiece, each with the development severe dyspnea at depth without excessive exertion. Associated symptoms included cough, weakness, expectoration of froth, chest discomfort, orthopnea, wheezing, hemoptysis, and dizziness. Emergency medical evaluation of four divers revealed rales on examination and pulmonary edema on chest radiograph. In one diver with pulmonary edema on chest radiograph, pulmonary capillary wedge pressure was normal when measured acutely. Symptoms resolved either spontaneously over 1-2 days or with standard medial treatment for pulmonary edema. Prior history of cardiovascular disease was negative except for hypertension and mitral valve prolapse in one diver. Cardiac evaluations following recovery from the acute episodes were normal. Episodes in the cold waters of Puget Sound sometimes occurred despite the use of dry suits. Furthermore, one diver developed recurrent episodes in 27 degrees C water off Cozumel, Mexico. Development of pulmonary edema while scuba diving constitutes a distinct clinical entity which may occur in either "cold" or "warm" water. It is not associated with a decompression mechanism. Personnel caring for divers should be aware of the syndrome in order to provide optimal medical management.

Ascariasis and hookworm (ancylostomiasis) remain the most common intestinal nematodes in the world with significant economic, social, and medical impact. An understanding of the transmission and pathogenesis of ascariasis and hookworm are necessary to recognize their clinical manifestations and to manage the pulmonary sequelae of infection. Transmission occurs predominantly in the tropics and rural areas where there is suboptimal sanitation, personal hygiene, and education regarding these parasites. Ascariasis generally occurs through hand-to-mouth ingestion of agricultural products or food contaminated with parasite eggs. Hookworm is transmitted through larval penetration of the skin. Larval pulmonary migration generally is asymptomatic. However, symptomatic pulmonary disease may occur with fever, cough, chest pain, hemoptysis, dyspnea, and wheezing due to (1) Loffler's syndrome, (2) the effects of larval tissue migration, (3) airway reactivity or bronchospasm, (4) infectious bacterial complications from parasitic migration and associated aspiration, and rarely (5) chronic eosinophilic pneumonia, transdiaphragmatic penetration, or symptoms of upper airway obstruction. Clinical evaluation shows pulmonary opacities on chest radiograph, peripheral blood eosinophilia, and larvae in respiratory or gastric secretions. Symptomatic treatment may be necessary with bronchodilators and systemic steroids or antibiotics for bacterial complications. The drug of choice is mebendazole (Vermox) 100 mg twice a day for 3 days. Alternatives include a single dose of pyrantel pamoate (Antiminth) 11 mg/kg (maximum dose, 1 g) or albendazole (Zentel) 400 mg orally once. Invermectin (Mectizan) is available through the World Health Organization, and, in the United States, through the manufacturer on a compassionate-use basis. Ivermectin is as effective as currently available drugs against Ascaris but shows only partial efficacy against hookworms, which infest humans. Preventive measures, improvement of sanitary facilities, education, and school screening may be important in the endemic areas to control these parasitic infections.

To investigate the relationship between exposure to organic solvents and the presence of pulmonary and upper respiratory tract mucous membrane symptoms, we conducted a cross-sectional study of 215 newspaper pressroom workers who were occupationally exposed to organic solvent and lubricant mixtures. Thirty-four compositors, who were not occupationally exposed to the solvents or lubricants, served as controls. Pressroom workers and compositors underwent spirometric testing and were also asked about the presence of cough, phlegm, hemoptysis, dyspnea, wheezing, chest tightness, nose or throat irritation, eye irritation, and sinus trouble. The spirometric results did not significantly differ between the two groups. However, the pressroom workers were significantly more likely to report pulmonary or upper respiratory tract mucous membrane symptoms than were compositors (P < 0.005). An exposure-response relationship could be demonstrated when comparing the number of solvents exposed with the total number of symptoms (P < 0.001). Similarly, an exposure-response relationship could be demonstrated when comparing the frequency of use of each of the seven solvents with the total number of symptoms (P < 0.002). Each of these findings was supported in a multivariable linear regression model that adjusted for potential confounders such as age, smoking history, and number of years in the industry. A high prevalence of these symptoms was reported even though the degree of exposure to solvents and lubricants was within the current permissible exposure limits.

An 84-year-old man was admitted to Yonezawa City Hospital with fever, cough, hemoptysis and progressive dyspnea. He had complained of wheezing asthmatoid and exertional dyspnea for the previous 10 years, regardless of the season. On admission, chest radiographs revealed a diffuse ground-glass shadow, fibrotic change, and volume reduction. Arterial blood gas analysis showed extreme hypoxemia. A computed tomographic (CT) scan of the chest showed not only faint ground-glass opacities and dense patches in the whole lung field, but also central bronchiectasis. Laboratory tests revealed that both total serum levels of IgE and specific IgE for Candida albicans were elevated. In the bronchoalveolar lavage fluid, lymphocyte, neutrophil and eosinophil percentages were high, and the CD4/CD8 ratio was low. We diagnosed the fibrotic stage of allergic bronchopulmonary candidiasis. During treatment with hydrocortisone and fluconazole, eosinophilia in the peripheral blood was observed, and serum candida antigen was positive. In addition, high serum levels of soluble interleukin 2 receptors were observed in this patient.

Asthma is one of the most common chronic medical conditions affecting children. The usual presenting symptoms of asthma include wheezing, shortness of breath, and dyspnea on exertion. Occasionally, children who present with one of these respiratory complaints have a less common disorder. Mediastinal fibrosis is a rare and incurable condition in which an excessive fibrotic reaction in the mediastinum causes progressive cardiopulmonary compromise. The presentation is variable: many patients present with respiratory symptoms such as cough, wheezing, dyspnea, and/or hemoptysis, while others are asymptomatic and present with a mediastinal mass discovered incidentally on a radiograph. With such a broad array of presenting complaints, and a clinical course characterized by slow progression of symptoms, the early stages of mediastinal fibrosis can mimic other diseases such as asthma, chronic bronchitis, or the superior vena cava syndrome. In this report we describe two patients with mediastinal fibrosis who were initially thought to have asthma.

The objectives of this study were to describe the clinical and radiological features at presentation, and the natural history of HIV-related bronchopulmonary Kaposi's sarcoma. A retrospective review of medical records and chest radiographs was performed in 106 HIV-infected homosexual men with bronchopulmonary Kaposi's sarcoma diagnosed at bronchoscopy between September 1988 and November 1994. The majority of patients had evidence of advanced HIV disease at diagnosis (median CD4 cell count was 15 x 10(6)/l, range 0-288), and 93% had had a diagnosis of cutaneous Kaposi's sarcoma for a median duration of 11 months prior to diagnosis of their bronchopulmonary disease. The most frequent symptoms at presentation were cough (92%), dyspnoea (69%), pleuritic pain (20%), haemoptysis (13%) and wheezing (10%). The most common radiological finding in 73% of our series was of poorly defined and confluent opacities, with predominant middle and lower zone involvement. Median survival was 4 months (range 0-37 months) from diagnosis and 9 months (range 1-25) from the onset of symptoms. Treatment with either chemotherapy or radiotherapy was associated with a significantly reduced risk of death (hazards ratio (HR)=0.48, 95% CI=0.26-0.87). Factors associated with a poor survival, after adjustment for treatment effect were older age (HR=1.79, 95% CI=1.22-2.84) for each 10-year increase in age; a history of pleuritic pain (HR=2.97, 95% CI=1.39-6.32); presence of pleural effusion on X-ray (HR=2.01, 95% CI=1.13-3.59) and a prior diagnosis of cutaneous Kaposi's sarcoma (HR=1.8, 95% CI=1.00, 3.24). Bronchopulmonary Kaposi's sarcoma occurs mainly in patients with advanced HIV disease and a prior history of cutaneous disease. Survival is poor, and adverse prognostic factors include older age at diagnosis and the presence of pleural disease.

We evaluated the relationship of clinical characteristics and survival in 1,635 patients with non-small cell lung cancer (NSCLC) treated in Brazil. The following variables were included: sex, age, smoking, Karnofsky's performance status (PS), weight loss, symptoms at diagnosis (cough, dyspnea, hemoptysis, chest pain, wheezing, and hoarseness), presence of superior vena cava syndrome (SVCS), histologic type, TNM stage, and therapeutic modality (surgery, chemotherapy [CT] and radiotherapy [RT]). Multivariate prognostic models were obtained by Cox regression. Patients unsuitable for surgery or who had recidivant disease were elected to further RT and/or CT, and long-term results in this group were equivalent to those in the group treated only by surgery. A diagnosis of bronchioloalveolar carcinoma, small tumors, absence of hoarseness, treatment by surgery, and RT were independent factors related to good overall survival in stage I and II. Weight loss and clinical signs of SVCS were related to poor prognosis in stage III. PS, diagnosis of adenocarcinoma or undifferentiated carcinoma, absence of weight loss and dyspnea, NO or N1 disease, ability to receive RT, CT, and to perform some palliative surgical procedure were good prognostic factors in stage IV. Clinical features of patients with NSCLC at diagnosis offer additional information to estimate their prognosis.

The foreign body aspiration is more frequent in children. The most usual etiology is the foreign bodies of vegetable nature, which can not be observed in the chest radiograph. The clinic signs are varied, including shortness of breath, cough and wheezing. Hemoptysis is a rare symptom, whose arising is generally connected with the existence of bronchiectasis. We present the case of a child who showed repeated hemoptysis and focal neumonitis due to Eikenelle corrodens three years after the aspiration of a spike. The diagnosis of the bronchial aspiration obtained after The most unusual in this case is the clinic manifestation of repeated hemoptysis, together with the long connected to the existence of foreign body inside the bronchus.

Pulmonary Embolism (PE) poses an important diagnostic problem in patients with chronic obstructive pulmonary disease (COPD). Indeed PE may aggravate the already precarious respiratory state of these fragile patients. Moreover, these two conditions share common symptoms: dyspnoea, wheezing, pleural pain, haemoptysis, palpitations and signs of right cardiac insufficiency. In two studies, one retrospective and the other prospective, we investigated the incidence of PE in patients with non-infective exacerbations of their COPD. The retrospective study was carried out over two years and involved 50 COPD patients with non-infective respiratory exacerbations. In this population, 10 patients out of 50 (20%) had a documented PE. No predictive factor was identified. The prospective study was conducted over one year and COPD patients admitted to hospital with exacerbations were included in the study if they had a positive D-dimer blood test and no evidence of acute respiratory infection. 31 patients were studied with Doppler ultra-sound examination of the legs and a lung perfusion scan. The presence or absence of PE was determined and the two groups were compared. 9 patients out of 31 (29%) had a documented PE. Six of these nine patients had a deep venous thrombosis (DVT). Two predictive factors of PE were identified: existence of a DVT and a significant fall in PaO(2) from baseline state (DeltaPaO(2) > 22 mmHg). We conclude that PE is a frequent (20 to 30%) of non-infective respiratory decompensation in COPD patients. Faced with an unexplained respiratory exacerbation in these patients, a lung perfusion scan should be routinely undertaken to rule out a PE when the D-dimers are positive.
