Hypoplastic pulmonary artery is an unusual congenital malformation. We describe a case of hypoplastic pulmonary artery diagnosed during the third trimester of pregnancy. The clinical and radiologic features mimicked pulmonary embolism, including hemoptysis, chest pain, pleural effusion, mild hypoxemia, and a suggestive ventilation-perfusion scan. Accurate differentiation of this entity from pulmonary embolism is necessary to obviate the need for prolonged anticoagulation.

On February 23, 1992, the Wisconsin Department of Health and Social Services (DHSS) was notified that 11 students from two high schools had been treated in two emergency rooms for acute respiratory symptoms (ARS) (i.e., cough, hemoptysis, chest pain, and dyspnea); two students were hospitalized. All of the students had participated in an indoor ice hockey tournament the previous night.

In order to derive guidelines for general practitioners on the value of chest radiography we prospectively reviewed all chest radiographs over a 10 month period. Radiographic chest examinations (frontal with or without a lateral view) were performed on 2017 patients in the radiology department or at the chest clinic. Patient details were noted, referring practice and waiting times monitored. The adequacy of the referral letter was assessed, and specific predetermined clinical findings were correlated with the radiographic findings. Results were divided into three groups (normal, abnormal with a clinically unrelated or chronic abnormality, and abnormal with a clinically related abnormality). Of these patients, 1245 (62%) had normal examinations and 460 (23%) had clinically related abnormalities. Abnormalities were rare in the 10-29 year age group, and when reassurance was sought for patients with symptoms of non-specific chest pain or general ill health. Patients presenting with haemoptysis or with symptoms of lower respiratory infection, or of chronic airways disease often had an abnormal radiograph. A clinical diagnosis was indicated or implied in 1664 (82%) and confirmed in 876 (53%). The most frequent reason for referral was for reassurance (618 patients). Guidelines based on age and symptoms should rationalize the use of chest radiography by general practitioners.

We have reviewed the role of radiation therapy in the palliative treatment of patients with non-small cell lung cancer. The use of radiation treatment results in effective palliation of chest symptoms such as dyspnea, cough, hemoptysis, and chest pain. In addition, the pain and suffering associated with skeletal and hepatic metastases are effectively alleviated by radiation therapy with minimal morbidity. Devastating neurologic complications can be avoided or alleviated in a great proportion of patients undergoing radiation therapy for cerebral metastases and spinal cord compression. Therefore, radiation therapy is a potent modality in relieving or reducing the suffering of patients with lung cancer. This is also a modality that has wide applicability; very few patients are not suitable candidates for that has wide applicability; very few patients are not suitable candidates for treatment regardless of their performance status. The aim of the treatments should always be prompt intervention using radiation therapy schedules that will minimize treatment time yet produce the desired results in a high proportion of patients. Protracted radiation schedules are not warranted in such patients except in special clinical situations. Palliation with radiation therapy is achieved quite promptly, with minimal side effects and a very small risk of any long-term consequences in patients who have a limited life expectancy.

Two policies of palliative thoracic radiotherapy for non-small-cell lung cancer have been compared in a randomised multicentre controlled trial. A total of 369 patients with inoperable, histologically or cytologically confirmed disease, too advanced for radical 'curative' radiotherapy, and with their main symptoms related to the primary intrathoracic tumour even if metastases were present, were studied. They were allocated at random either to a regimen of 17 Gy given in two fractions of 8.5 Gy 1 week apart (F2 regimen), or to a conventional multifractionated regimen of either 30 Gy in ten fractions or 27 Gy in six fractions (a biologically equivalent dose), given daily except at weekends (FM regimen). On admission, 93% of the patients had cough, 47% haemoptysis, 57% chest pain, 58% anorexia, and 11% dysphagia. As assessed by the clinicians, palliation of the main symptoms was achieved in high proportions of patients ranging in the F2 group from 65% for cough to 81% for haemoptysis and in the FM group from 56% for cough to 86% for haemoptysis. Haemoptysis, chest pain, and anorexia disappeared for a time in well over half the patients with these symptoms, and cough in 37%. For all the main symptoms, the median duration of palliation was 50% or more of survival. Performance status improved in approximately half of the patients with a poor status on admission. All these results were similar in the two treatment groups. As assessed daily by the patients using a diary card, the quality of life deteriorated slightly during treatment but then improved steadily during the next 5 weeks. The proportion of patients with dysphagia increased considerably during treatment, but fell to the pretreatment level during the next 2 weeks. The results were similar in the two groups. Radiation myelopathy was suspected in one (F2) patient. There was no difference in survival between the two groups (log-rank test), the median survival time from the date of allocation being 179 days in the F2 and 177 days in the FM group. In the light of all the findings, the regimen of two fractions of 8.5 Gy given 1 week apart is recommended.

We determined the prevalence of respiratory symptoms and lung dysfunction in a large sample of habitual smokers of freebase cocaine ("crack") alone and in combination with tobacco and/or marijuana. In addition, we compared these findings with those in an age- and race-matched sample of nonusers of crack who did or did not smoke tobacco and/or marijuana. A detailed respiratory and drug use questionnaire and a battery of lung function tests were administered to (1) a convenience sample of 202 habitual smokers of cocaine (cases) who denied intravenous drug abuse and (2) a reference sample of 99 nonusers of cocaine (control subjects). The cocaine smokers (85% black) included the following: 68 never-smokers of marijuana, of whom 43 currently smoked tobacco and 25 did not, and 134 ever-smokers of marijuana (42 current and 92 former), of whom 92 currently smoked tobacco and 42 did not. The control subjects (96% black) included the following: 69 never-smokers of marijuana, of whom 26 currently smoked tobacco and 43 did not, and 30 ever-smokers of marijuana (18 current and 12 former), of whom 21 currently smoked tobacco and 9 did not. Cases smoked an average of 6.5 g cocaine per week for a mean of 53 months. The median time of the most recent use of crack prior to study was 19 days (range less than 1 to 180 days). After controlling for the use of other smoked substances, frequent crack use was associated with: (1) a high prevalence of at least occasional occurrences of acute cardiorespiratory symptoms within 1 to 12 h after smoking cocaine (cough productive of black sputum [43.7%], hemoptysis [5.7%], chest pain [38.5%], usually worse with deep breathing, and cardiac palpitations [52.6%]) and (2) a mild but significant impairment in the diffusing capacity of the lung.(ABSTRACT TRUNCATED AT 250 WORDS)

The development of a malignant esophagorespiratory fistula is a devastating complication. Data comparing various treatment options in a large group of patients are sparse. To assess the results of therapy, we reviewed our experience in 207 patients with malignant esophagorespiratory fistula. Records of 207 patients admitted to our institution with malignant esophagorespiratory fistula from 1926 to 1988 were reviewed and results of management analyzed. Age ranged from 21 to 90 years (median, 59 years); the male/female ratio was 3:1. Primary tumor site was esophagus in 161 (77%), lung in 33 (16%), trachea in 5 (2%), metastatic nodes in 4 (2%), larynx in 3 (1%), and thyroid in 1. Symptoms and signs of malignant esophagorespiratory fistula included cough in 116 (56%), aspiration in 77 (37%), fever in 52 (25%), dysphagia in 39 (19%), pneumonia in 11 (5%), hemoptysis in 10 (5%), and chest pain in 10 (5%). Respiratory location of fistula included trachea in 110 (53%), left main bronchus in 46 (22%), right bronchus in 33 (16%), lung parenchyma in 13 (6%), and multiple sites in 5 (2%). The percentage of patients alive at 3, 6, and 12 months by treatment modality was 13%, 4%, and 1% for supportive care (n = 104); 17%, 3%, and 0% for esophageal exclusion (n = 29); 21%, 14%, and 0% for esophageal intubation (n = 14); 30%, 15%, and 5% for radiation therapy (n = 20); and 46%, 20%, and 7% for esophageal bypass, respectively. Patients treated with radiation therapy and esophageal bypass had a significantly prolonged survival compared with patients treated with the other modalities.(ABSTRACT TRUNCATED AT 250 WORDS)

Most cases of blastomycosis are sporadic and only nine outbreaks representing a total of 112 cases have previously been reported. Less than half of these have been culture proven cases. Outbreaks have previously occurred in North Carolina, Minnesota, Illinois, Wisconsin and Virginia. We report three culturally confirmed cases of blastomycosis from Elizabethton, Tennessee, who had onset of illness within a one-week span of time. The patients presented with fever, chest pain, weight loss, poor appetite and myalgia. Each initially had a dry cough which became productive of purulent sputum as the illness progressed. Mild hemoptysis occurred during each patient's course. Serologic testing by immunodiffusion and enzyme immunoassay were positive and testing by complement fixation was negative in each case. The diagnosis was made by histopathology on transbronchial biopsy or transthoracic needle aspiration material. Each patient improved on ketoconazole therapy.

A 58-year-old female was admitted with an abrupt onset of chest and back pain. The CT scan of the chest showed aortic dissection of the ascending aorta and proximal aortic arch, but the false lumen of the aortic dissection had already been occluded by a blood clot. After admission, she complained of chest pain with hemoptysis and presented facial edema and the distention of the neck veins. The pulmonary angiogram showed complete occlusion of the right pulmonary artery at the proximal segment. These findings were interpreted as pulmonary embolism. She was treated with intravenous heparin and urokinase, but these treatments did not demonstrate any improvement. She underwent a surgical exploration on the fourth hospital day. During surgery, the right pulmonary artery was discovered to be compressed and occluded by the large dissecting aneurysm of the ascending aorta. In addition, hematoma was seen between the right pulmonary artery. The ascending aorta and pulmonary trunk, which was injured in the operative procedure, were replaced with an artificial graft successfully. Postoperative pulmonary angiogram showed no stenosis of right pulmonary artery. The occlusion of the pulmonary artery by an acute dissecting aneurysm is an extremely rare complication and it is often wrongly diagnosed as pulmonary embolism. In such cases, the correct diagnosis and prompt surgical treatment is essential and antithrombolytic and anticoagulant therapy should be avoided.

The population of two villages of Chagalnaiya Upazila was selected for a study on the prevalence of pulmonary tuberculosis through a two stage screening process. Initial screening was conducted on 3406 persons which is 78% of the total population (3920) of the two villages. The initial screening revealed 182 persons with the history of cough lasting 4 weeks or more, chest pain, continuous fever and haemoptysis. Sputum examinations for Acid Fast Bacilli (AFB) of tuberculosis detected 21 sputum positive cases giving a prevalence rate of 6.2 (per 1000 population) higher than the estimated national average of 5.0 per 1000. Most of the cases were not receiving treatment. Some social and environmental factors of suspected and detected cases were also studied.
