The delayed health effects from accidental exposure to bromine vapors in a group of six people were evaluated. During the acute exposure, they had only some respiratory symptoms and skin burns of first to second degree involving small areas. All were treated in one hospital and released within 1-4 d. Six to 8 wk later, some still had health complaints such as cough, shortness of breath, chest tightness, eye irritation, headache, dizziness, fatigue, and memory, sleep, and sexual disturbances, but no objective laboratory or clinical evidence of effects. Mechanisms that might have led to manifestations of such complaints 1-2 mo after the accident are discussed and possible ways to alleviate similar situations are suggested.

A 63-year-old man with pulmonary sarcoidosis, diagnosed by mediastinal lymph node biopsy in 1977, was admitted in Feb. 1987 because of shortness of breath and cough. Chest X-ray showed bilateral hilar lymphadenopathy and a tumor shadow in the right lung field. Histological examination of specimens biopsied from the right lung revealed small cell carcinoma (S.C.C.). Bronchoalveolar lavage was performed to evaluate the disease activity of sarcoidosis, and the total number of cells and T-lymphocytes; the ratio of CD4+ cells to CD8+ cells was not increased. He was treated with combination chemotherapy, however, he died of respiratory failure after 7 months. An autopsy was performed, and the lesions were examined histologically. The sarcoid lesion in a lymph node obtained at autopsy was not active, in contrast to that obtained by mediastinal lymph node biopsy. Lung cancer and sarcoidosis are both common diseases, but their coexistence in the same patient is not common, and autopsied cases are rare. In this case, an autopsy was performed, and BAL had been performed prior to his death. The relationship between the BAL findings and the histology of sarcoidosis was examined. Based on the results of autopsy and BAL, the sarcoidosis was inactive prior to death, but had been histologically active 10 years previously. Therefore, this is a very interesting case, since we can examine the relationship between the two diseases, and the progression of each disease. This case also provides an interesting example of differentiation of sarcoidosis from S.C.C. Metastatic invasion of the hilar lymph nodes without bronchial stenosis and changes secondary to stenosis may often occur in patients with small cell lung cancer. Such metastatic invasion closely resembles the bilateral hilar lymphadenopathy of sarcoidosis; therefore, in some cases, it may be extremely difficult to differentiate the two diseases.

Although the purported incidence of pacemaker syndrome according to the literature is only 5%-15%, this is based on a series of patients with VVI pacing. Increasing numbers of studies are being reported in which patients prefer the dual chamber mode despite little benefit being demonstrated on objective testing, suggesting that pacemaker syndrome may be more common than is generally reported. This study was designed to evaluate the reported symptoms in a series of patients programmed to both the VVI and one or more dual chamber modes. Forty unselected patients with dual chamber pacemakers were entered into a blind, randomized trial comparing the symptoms associated with VVI pacing to those associated with dual chamber pacing. Patients were randomized to either VVI or dual chamber pacing. At the end of 1 week, questionnaires rating 16 different symptoms were completed. Blood pressure, LV function, presence of ventriculoatrial conduction, and ability to override the pacemaker were evaluated. The pacemaker was then programmed to the other mode. Overall, 12 of 16 symptoms were significantly worse in the VVI as compared to dual chamber mode. The most highly significant (P less than 0.005) were shortness of breath, dizziness, fatigue, pulsations in the neck or abdomen, cough, and apprehension. Pacemaker syndrome was clinically recognized in 83% of patients paced in the VVI mode with 65% of patients experiencing moderate to severe symptoms. There were no readily identified clinical, hemodynamic, or electrophysiological parameters that predicted which patients would develop pacemaker syndrome. Thus, when patients have an opportunity to experience both pacing modes in close proximity to one another, there is a high incidence of pacemaker syndrome in the VVI mode.

Thirty-eight patients were treated with high dose rate endobronchial brachytherapy to palliate symptoms (cough, hemoptysis, fever, and/or shortness of breath) caused by endobronchial of previously irradiated (greater than or equal to 5000 cGy) bronchogenic carcinoma. The dose per fraction was 600 cGy at a radius of 1 cm from the center of the linear path of the source, and each patient received three fraction, each fraction separated by a 1-week interval. Twenty-nine patients (76%) had symptomatic improvement, 16 with complete and 13 with partial relief of symptoms. The likelihood of symptom relief was greater in those patients who had extra-bronchial tumor measuring less than 5 cm (15/15) compared to those with extra-bronchial tumor measuring greater than or equal to 5 cm (2/8). The median duration of symptom relief was 7.5 months. Repeat bronchoscopy done 3 months after brachytherapy revealed that 41% (11/27) had complete tumor regression and another 41% (11/27) had partial regression. Nine of 14 patients with post-obstructive atelectasis/pneumonitis had radiographic improvement. Twelve patients (32%) died from massive hemoptysis occurring 2-56 weeks (median 10 weeks) after brachytherapy. Location of the recurrence was the most important predictor of pulmonary hemorrhage. It occurred only in patients with recurrence in the right upper lobe, right mainstem, or left upper lobe bronchus. Whether this high rate of fatal pulmonary hemorrhage was a real phenomenon or a statistical fluke of small numbers remains an unanswered question.

Exercise-induced asthma is a common but frequently undiagnosed problem. The patient may not wheeze, but rather have shortness of breath, chest tightening, and coughing. The coach and the physician must be particularly alert to the signs and symptoms of exercise-induced asthma to recognize this syndrome. Proper conditioning, warming up, inducing refractoriness, participating in sports less likely to provoke exercise-induced asthma, and the aggressive use of appropriate medications allow patients to enjoy sports and compete effectively. A rare but potentially fatal syndrome is exercise-induced anaphylaxis. Accurate diagnosis and differentiation from other exertion-related syndromes are critical, and appropriate precautions are necessary. A third clinical entity, exercise-induced cholinergic urticaria, although not life-threatening, can be quite annoying. Aggravating factors, such as increased heat, compound the problems. In summary, exercise-induced allergic phenomena are common and should be recognized by the practicing physician.

In a double-blind study involving two groups of ten patients with chronic obstructive bronchitis, the expectorant Gelomyrtol forte was tested against placebo for its effectiveness and tolerance. The parameters: amount of sputum, Rt and IGV, together with all the usual clinical laboratory parameters, were determined. In addition, the color of the sputum was always noted. On the basis of patient scores, daily entries on the ability to expectorate, attacks of coughing, general coughing, and shortness of breath were made by the patients for the duration of the 14-day treatment period. On conclusion of the study, the patients were asked to assess the effectiveness of the supplementary medication, and the care-providing physician also assessed effectiveness. All score parameters related to coughing improved, in some cases appreciably, relative to the placebo group. The findings in term of sputum volume and color, were also distinctly better in the Gelomyrtol forte group. Correspondingly, both patients and physicians assessed the effectiveness of Gelomyrtol forte to be distinctly better than that of the placebo. Although the groups are relatively too small and heterogeneous, to establish statistically significant differences, the results do strongly suggest a favorable and major effect in patients with relevant cough symptoms. Both subjective and objective tolerance was excellent.

Duodenobronchial fistulas are an extremely rare subgroup of abdominobronchial fistulas, which include bronchobiliary, gastrobronchial, enterobronchial, colobronchial, and splenobronchial fistulas. Only one case of a duodenobronchial fistula has been previously reported. Duodenobronchial fistulas occur as a complication of a duodenal injury. The characteristic symptoms are a cough that produces copious bilious secretions, shortness of breath, and fever. The diagnosis is made by contrast gastrointestinal studies. Treatment requires an abdominal approach with interruption of the fistula at its duodenal origin and control of the inciting inflammatory process. With prompt diagnosis and treatment, thoracic drainage or pulmonary resection should not be needed.

We present the clinical and biopsy findings of a 63-yr-old white male with interstitial pulmonary fibrosis and a long history of extensive exposure to mica while working in the rubber industry. The patient presented 30 yr after the initial exposure with complaints of progressive shortness of breath and a chronic nonproductive cough. Pulmonary function testing revealed restrictive lung function with a mild reduction in the total lung capacity (80% of predicted) and a moderate-to-severe reduction in the diffusing capacity of carbon monoxide (50% of predicted). The chest radiogram and high-resolution chest CT scan showed diffuse fibrosis and focal honeycombing involving the upper and lower lung zones bilaterally. Bronchoalveolar lavage revealed 20% neutrophils in the lavage fluid with abundant rectangular flaking crystals. Open-lung biopsy exhibited extensive fibrosis and architectural remodeling with abundant sheets and fragments of engulfed polarizable crystalline material. Energy-dispersive spectroscopy and electron diffraction studies confirmed the material to have the features of mica. Asbestos and other silicates were not identified. The documentation of prolonged exposure to mica, the clinical and radiographic features of severe interstitial fibrosis, and the histopathologic delineation of the interstitial lesion, including spectroscopic and crystallographic verification of crystalline mica, support the causal relationship between mica and interstitial fibrosis.

Two patients with lymphomatoid granulomatosis were diagnosed by postmortem autopsy or exploratory thoracotomy. The lung, skin, spleen, renal and lymph nodes were involved. The most common presenting complaints are fever, cough, expectoration shortness of breath. The radiographic manifestations are multiple, bilateral nodular shadows. The histologic features is a unique form of pulmonary angiitis and granulomatosis, which is a necrotizing angiocentric and angio-destructive infiltrative process composed of small lymphocytes and atypical lymphoreticular cells.

Pneumocystis carinii pneumonia (PCP) is the most common index diagnosis in patients with acquired immunodeficiency syndrome (AIDS). Eighty percent of AIDS patients will eventually develop PCP. Common presenting symptoms are shortness of breath, cough, weight loss, and fever. The chest radiograph typically reveals a diffuse, bilateral, symmetric, fine-to-medium reticulonodular pattern of opacities. Upper lobe disease has been reported recently in patients who have undergone prophylactic therapy with aerosolized pentamidine. Pneumatoceles, or thin-walled air-containing cysts, have been noted in 10% of patients with PCP. Lymphadenopathy and pleural effusion are extremely rare. Therapy with various agents is generally successful, resulting in clinical and radiographic improvement within 7 to 10 days. Recurrence of PCP is common.
