Occult infections during sickle cell pain crisis can be associated with significant morbidity. It has been suggested that empiric workup for pneumonia and urinary tract infection (UTI) is required. A study was undertaken to determine whether clinical criteria can be used to exclude such infections as precipitants of pain crisis in adults. This retrospective, observational clinical study was conducted in an inner-city teaching hospital emergency department (ED) with 95,000 visits/year. Patients 18 years of age or older presenting to the ED with sickle cell pain crisis who had not used antipyretics within 6 hours before presentation were eligible. Ninety-four visits were evaluated. During initial evaluation the treating physician completed a questionnaire addressing systemic, pulmonary, and urinary tract signs and symptoms. Temperature and physical examination were recorded on an ED memo. Treatment modalities were at the discretion of the treating physician. All patients had a complete blood count, reticulocyte count, urinalysis, and chest radiograph. If the urinalysis was positive (>2 white blood cells) or the patient had clinical evidence of a UTI, a urine culture was obtained. UTI was confirmed through a urine culture with >100,000 colony-forming units/mL. Chest X-rays were reviewed by a staff radiologist. Definitive diagnosis of pneumonia was made by the presence of an infiltrate and a positive clinical response to antibiotic therapy. Thirty-eight patients totalling 94 visits to the ED were studied during an 18-month period. Six diagnoses of pneumonia and 3 diagnoses of UTI were made. All six patients with pneumonia had at least 4 of the signs and symptoms including fever, chills, cough, shortness of breath, sputum production, chest pain, hemoptysis, abnormal pulmonary examination, and temperature of >37.8 degrees C. Of the three patients with UTI, two had signs and symptoms inconsistent with UTI (asymptomatic bacteriuria). In patients with sickle cell pain crisis, medical history and physical examination can be useful to predict the absence of pneumonia, but may not be as beneficial in predicting the absence of UTI. These results suggest that empiric chest x-ray may be unnecessary to exclude pneumonia; however, routine urinalysis may be indicated. Because of the low incidence of these infections, larger studies are required to confirm these findings.

Approximately one half of prescribed radiotherapy is given for palliation of symptoms due to incurable cancer. Distressing symptoms including pain, bleeding, and obstruction can often be relieved with minimal toxic effects. Painful osseous metastasis is common in oncologic practice. Ninety percent of patients with symptomatic bone metastases obtain some pain relief with a lowdose, brief course of palliative radiotherapy. One half of the responding patients may experience complete pain relief. A single dose of 800 cGy in the setting of painful bone metastasis may provide pain control comparable to more protracted treatment at a higher dose of radiation. Patients with lytic disease in weight-bearing bones, particularly in the presence of cortical destruction, should be considered for prophylactic surgical stabilization of their condition. Routinely a brief, fractionated course of radiotherapy is given postoperatively. Pain due to multiple bone metastases uncontrolled by analgesics can be managed with single doses of halfbody irradiation. Doses of 600 cGy delivered to the upper half-body (above the umbilicus) and 800 cGy to the lower half-body (from the umbilicus to the middle of the femur) will provide some pain relief in 73% of patients. Half-body techniques have been investigated as prophylactic treatment, as a complement to local-field irradiation, and as fractionated rather than singledose therapy. Although intravenous administration of strontium 89 has been associated with myelosuppression, this treatment has been shown (a) to relieve pain due to bone metastasis and (b) to delay development of new painful sites. Recent data from phase III trials demonstrated that bisphosphonates have a role in reducing skeletal morbidity due to bone metastasis. Bone pain was reduced, and the incidence of pathologic fracture and the need for future radiotherapy was decreased. Radiotherapy relieves clinical symptoms in 70% to 90% of patients with brain metastases. Brief treatment schedules (e.g., 2000 cGy in five fractions over 1 week) are as effective as more prolonged therapy. Patients with solitary brain metastasis and no extracranial disease or controlled extracranial disease should be considered for surgical resection, because phase III data indicate enhanced survival with such an approach. Whole-brain radiotherapy is routinely administered postoperatively. A phase III study is examining the impact of accelerated fractionated doses of radiotherapy (two treatments per day) on survival of patients with brain metastases. Stereotaxic radiosurgical treatment is becoming increasingly available and permits delivery of radiation to metastatic intracranial tumor with minimal exposure of normal surrounding brain This treatment is most commonly used at the time of a solitary recurrence of disease in patients who previously received whole-brain radiotherapy. A role for this modality in newly diagnosed brain metastases remains to be defined. Chest symptoms are common in patients with locally advanced lung cancer and are effectively palliated with one 1000 cGy or two 850 cGy one fraction doses of radiation to the thoracic inlet and mediastinum. Chest pain and hemoptysis are more effectively palliated than cough and dyspnea. In patients with stage III cancer there is no compelling evidence that radiotherapy confers a survival advantage, and it may be reasonable to administer thoracic radiotherapy only when the patient has significant symptoms and the goal is to achieve control of these symptoms. Approximately 75% of the cases of superior vena cava syndrome are due to lung cancer, and small-cell lung cancer is the most common histologic type. A histologic diagnosis should be obtained before treatment is started, because detection of lymphoma or small-cell carcinoma would necessitate systemic therapy. Eighty percent of the patients with vena cava syndrome due to malignant disease achieve symptom relief with a brief, fractionated, palliative course of rad

Recent studies have indicated that chemotherapy not only provides some survival benefit, but also reduces tumor-related symptoms and improves the performance status of patients receiving chemotherapy. Data from single-agent gemcitabine studies demonstrate improvements in a range of tumor symptoms, including cough, hemoptysis, pain, dyspnea, and anorexia, as well as increases in performance status. Indeed, more patients benefit from gemcitabine chemotherapy than suggested by the objective response rate. Surveys also have shown that patients are much more likely to accept chemotherapy for what is perceived by health care professionals as potentially small benefits. Gemcitabine has a role in the palliative treatment of patients with advanced non-small cell lung cancer.

Tracheobronchial ruptures are rare but potentially lifethreatening events. We report on the case of a 34-year-old suicidal unrestrained car driver, who developed subcutaneous and mediastinal emphysema and right-sided haematothorax following blunt thoracic trauma. Fibreoptical inspection of the tracheobronchial system revealed a rupture (approximately 2 cm in length) of the pars membranacea of the trachea ending shortly above the carina. CT-scan confirmed the diagnosis of mediastinal emphysema, tracheal rupture and, in addition, left-sided pulmonary contusion. A repair of the tracheal tear was performed by right-sided thoracotomy using a double-lumen tube. The left-sided double-lumen tube was used postoperatively to achieve respirator ventilation with low pressure on the tracheal lumen and on the suture of the tracheal tear. On the other hand, sufficient airway pressure with PEEP for the left lung showing contusion could be provided, using the endobronchial tube. The postperative course was without complications. The patient was on respiratory support for three days due to his-pulmonary contusion. Following final endoscopic control of the trachea he was discharged from the ICU one week after the trauma. The clinical and radiological signs of tracheobronchial ruptures are discussed (respiratory distress, haemoptysis, cyanosis, localised pain, hoarseness, coughing, dysphagia, stridor, subcutaneous emphysema and pneumothorax, tension pneumothorax, mediastinal emphysema). Fibreoptic bronchoscopy is the present gold standard for confirming the diagnosis. The surgical and anaesthesiological approach to the management of tracheobronchial ruptures is described reviewing the current literature.

To assess the efficacy and toxicity of an outpatient combination chemotherapy in small-cell lung cancer (SCLC), we treated 70 consecutive patients with epirubicin 80 mg m(-2) i.v. on day 1 and etoposide 200 mg o.d. p.o. on days 1-4 (EE) at 3-weekly intervals. The median age of patients was 64 years (range 39-84). The male-female ratio was 42:28 and 35 (50%) had metastatic disease. Fifty-seven patients were evaluable for response. The overall response rate was 64.4%, including 14 (23.7%) complete responses and 24 (40.7%) partial responses. Median time to progression was 7 months in responders and 8 months in patients with limited disease. The median survival in patients with limited disease was 10.5 months (range 0.5-70 +) and 7 months (range 0.5-24) in those with extensive disease. Improvement of symptoms occurred in 79% of patients with shortness of breath, 80% with cough, 81% with haemoptysis and 68% with pain. In 19 patients an increase in body weight was noted. Major (WHO grade 3/4) toxicities were neutropenia in 13 (18.5%) patients, alopecia in 33 (47.1%) patients, mucositis in 15 (21.4%) patients, anorexia in eight patients (11.4%), nausea and vomiting in six patients (8.5%) and diarrhoea in 4 (5.7%) patients. In conclusion, EE is an active and well-tolerated outpatient regimen in the treatment of SCLC. The survival data in this unselected group of patients were disappointing and the possible explanations for this are discussed.

Children acquire blastomycosis, with rare exceptions, through the respiratory route. Nearly half of those who are infected may be asymptomatic. Cough is the most common symptom and is usually without sputum production, and hemoptysis is not noted. Other symptoms are chest pain (described as tightness or pain when breathing), weight loss, night sweats, and loss of appetite. The severity of illness is variable and may simulate an upper respiratory infection, bronchitis, pleuritis, or pneumonia. As in adults, an overwhelming infection may cause respiratory failure even in immunocompetent children and in immunocompromised children who live in or travel to endemic areas are susceptible to infection. Some reports based on consecutive cases note extrapulmonary dissemination commonly in children, whereas dissemination is rarely noted in outbreak cases. Chronicity of the disease favors extrapulmonary dissemination. Chest radiograph patterns are alveolar infiltrates, consolidation, and nodule(s), and these may be accompanied by cavitation. Diagnosis is suspected when the symptoms that mimic common respiratory infections persist for more than 2 weeks and by a history of residence or travel to an endemic area. Chest radiographic findings of nodule(s) or cavitation further increase the suspicion. Confirmation of diagnosis is by microscopic examination and culture of sputum. When expectorated sputum is unavailable, bronchoscopy with lavage and biopsy or percutaneous needle biopsy of lung is the appropriate next step. Disease that is progressive or severe or disseminated to other organs should be treated. Amphotericin B is effective and results in excellent cure rates. Experience using oral azoles is limited in children.

Forty cases of carcinoid tumors of the lung were studied retrospectively from 1989-1993 in the Pathology Department of Hospital Pulido Valente in Lisbon. The mean age of patients was 44 years old, and the presenting symptoms included hemoptysis, cough, thoracic pain, fever, and dyspnea. An endobronchial mass was seen in 75% of the cases. The histopathological study was based on the following morphological criteria: disorganized architecture with increased cellularity (8 cases; 20%), nuclear pleomorphism (14 cases; 22%), the presence of coarse chromatin (19 cases; 30%), increased mitotic activity (13 cases; 21%), enlarged nucleoli (17 cases; 27%), necrosis (12 cases; 25%), vascular permeation (8 cases; 15%), distant metastasis (6 cases; 14%). Chromogranin was the most strongly reliable immunostaining for the diagnosis. In our series the initial routine diagnosis and the diagnosis after morphological criteria evaluation matched, and in 14 cases the final diagnosis was of atypical carcinoids.

The efficacy of palliative radiotherapy of NSCLC was evaluated. 70 patients with histologically and cytologically confirmed advanced NSCLC were palliativelly irradiated in Department of Oncology I. Medical Faculty Charles University, Prague, in the period 1/93-12/94. 46 patients were evaluable for response (32 men, 14 women, median age 66.1, range 46-82). Median survival was 24.5 weeks. The most frequent intrathoracal symptoms were: cough 54%, chest pain 41%, dyspnoe 54%, hemoptysis 13%, VCS sy 7%. Palliation of the main symptoms has been achieved in 68% for cough, in 83% for hemoptysis, in 89% for chest pain, in 60% for dyspnoe and in 100% for VCS sy (in combination with chemotherapy). The median duration of palliation was 14.7 weeks for all the main symptoms, e.g. more than 50% of overall survival. Two fractionations schedules for the chest radiotherapy were used: 30 Gy/10 fr/2 wks (67%) or short regimens 8-20 Gy/1-2 fr/1-2 wks (33%). The results of palliation and survival are similar for both treatment schedules. Side effects has been infrequent, only 6 patients (13%) had dysphagia during the treatment. Radiation myelopathy has been not observed in any case. The therapeutical effect has been achieved in the more than 80% cases of pain, hemoptysis and VCS syndrome.

To determine the efficacy of doxycycline in producing pleuroedesis in patients with malignant pleural effusion (MPE), 31 documented cases of MPE, aged 19-82 years were prospectively studied. Pleural sclerosis was done with 500 mg of doxycycline. Response regarding respiratory symptoms and pleural fluid accumulation were evaluated monthly. At one month, 27 patients were evaluable (4 dropped out). All responded and required no therapeutic thoracentesis. At 3 months, 13 patients dropped out, only 14 patients were evaluable. It revealed that 13 out of 14 patients (92%) responded. Only one patient failed and required therapeutic thoracentesis. Five and two patients came for assessment at 6 and 12 months, respectively. They still benefited from doxycycline pleurodesis. Side effects including low grade fever in 30% of patients, moderate to severe pain in 60% and troublesome cough with hemoptysis in one patient (3%) were noted. Doxycycline is an effective agent in controlling MPE. It was successful in every patient at 1 month and in 92% at 3 months. At 6 and 12 months quite a few patients survived for evaluation. However, they still benefited from doxycycline pleurodesis. Side effects were tolerable.

Unilateral pulmonary vein atresia is a rare condition in adults that may cause serious diagnostic problems because of unspecific clinical findings. A 28-year old female patient is described who presented with signs of recurrent pulmonary embolism with shortness of breathing, unilateral thoracic pain and several episodes of haemoptysis. Ventilation and perfusion scans showed a total lack of perfusion in the right lung with only slight disturbance of ventilation. However, no marked increase of pulmonary artery pressure and no signs of a recent thrombosis of peripheral veins were found. Transoesophageal echocardiography and pulmonary angiography in combination with aortography revealed the diagnosis of unilateral pulmonary vein atresia with abnormal branches of bronchial arteries. There is a considerably left-to-right shunt with return of flow from the bronchial arteries to the right and afterwards to the left pulmonary artery. Clinical, radiological and nuclear medical findings as well as therapeutical options are described.
