The clinical picture of Reye's syndrome, characterized by an acute severe disease of brain and liver, initially has nonspecific generalized symptoms with cough, myalgia, and fever. The prognosis is poor. The disease starts with an infection, quickly followed by vomiting and loss of consciousness. In this phase the serum bilirubin is moderately raised, the transaminases markedly so. In addition to gastro-intestinal bleeding there may be hypoventilation, hypoglycaemia and seizures. Morbid anatomically there is a small-drop fatty infiltration of the liver and other organs with cerebral oedema. Aetiology and pathogenesis remain uncertain. Numerous therapeutic measures have been proposed.

The incidence of systemic side effects under aerosolized pentamidine treatment or prophylaxis for pneumocystis carinii pneumonia is low when compared to intravenous application. Erythema, hypotension, hypoglycemia, renal failure are infrequently seen. Local side effects--cough, bronchial spasm, metallic taste--are frequent complications of aerosolized pentamidine treatment. Cystic lung disease, pneumothorax, and atypical pneumonia may be a late sequelae of pneumocystis carinii pneumonia, and not a primary effect of pentamidine. Poor apical ventilation due to suboptimal inhalation technique etc. and decreased deposition of pentamidine in these areas may be of some consequence for the development of these unusual complications. Extrapulmonary pneumocystis infections under preventive pentamidine aerosol treatment for pneumocystis carinii pneumonia have been seen in single cases, a causal relationship to pentamidine application is not yet established.

The continuing growth of the acquired immunodeficiency syndrome (AIDS) epidemic has caused a parallel increase in patients with Pneumocystis carinii pneumonia (PCP). PCP has a wide spectrum of severity, from mild disease to severe parenchymal lung damage. Outcome is determined by severity of lung injury, the underlying physical condition of the patient, and concomitant infections. Both trimethoprim-sulfamethoxazole (TMP-SMX) and pentamidine are effective therapeutic agents; however, both cause a high incidence of adverse reactions. TMP-SMX therapy can be made safer by careful monitoring and dose adjustment. Pentamidine toxicity, especially hypoglycemia, appears to be cumulative dose-dependent. Experimental therapies, including TMP-dapsone and aerosolized pentamidine, appear promising in mild to moderate disease, while trimetrexate may be more effective in severe disease. Corticosteroids are unproven in decreasing mortality. Prophylaxis of PCP is possible with TMP-SMX but the high rate of adverse reactions make long-term therapy difficult. Other oral therapies such as dapsone, pyrimethamine/sulfadoxine are also promising but not yet tested. Aerosolized pentamidine is effective and safe for prophylaxis regimen when administered correctly. Airway irritation as manifested by cough and/or wheezing is a common adverse effect of aerosolized pentamidine.

We reviewed 223 localized fibrous tumors of the pleura and divided them histologically into 141 benign and 82 malignant neoplasms. The criteria used for a judgement of malignancy were high cellularity and mitotic activity (more than four mitotic figures per 10 high-power fields), pleomorphism, hemorrhage, and necrosis. The tumors occurred equally in both sexes, most commonly in the sixth to seventh decades of life. Presenting symptoms included chest pain, dyspnea, and cough; they were observed in three-fourths of patients with a malignant tumor. One in every four of these patients had hypoglycemia, clubbed digits, or pleural effusion. Two-thirds of the tumors were attached to visceral pleura, often by a pedicle. The rest arose from the parietal pleura of the chest wall, diaphragm, or mediastinum. Neoplasms in these atypical sites, together with fissural lesions and tumors "inverted" into peripheral lung, were more often malignant. Most neoplasms measured 5-10 cm and weighed 100-400 g. Microscopically, the "patternless pattern," or hemangiopericytic type, was seen in the majority of cases, and mixed patterns were seen in nearly 40% of tumors. Of the 169 tumors where follow-up was available, all of the benign and 45% of the malignant tumors were cured by simple excision. Patients surgically cured of a malignant neoplasm had pedunculated or well-circumscribed lesions. However, 55% of patients with malignant tumors succumbed to their disease secondary to invasion, recurrence, or metastasis. Resectability is the single most important indicator of clinical outcome. No tumor expressed epithelial differentiation, either immunohistochemically or ultrastructurally; therefore, we favor the term "localized fibrous tumor" of pleura instead of "localized mesothelioma."

Fourteen cases of a mediastinal neoplasm identical to solitary fibrous tumor (so-called fibrous mesothelioma) of the pleura were observed. The lesions presented with cough, chest pain, dyspnea, or as asymptomatic masses detected radiographically. Two patients had associated hypoglycemia. Eleven of the tumors were in the antero-superior mediastinum. One arose on a pedicle from the thymus, and another had entrapped thymic elements. Tumor cells were variably immunoreactive for vimentin and actin, but not for keratin, and lacked ultrastructural evidence of mesothelial or epithelial differentiation. Eight cases had highly cellular mitotically active regions of which six of seven with follow-up behaved aggressively; the exception was the pedunculated tumor. A 13-cm, histologically bland tumor has recurred twice. Aggressive behavior was more common than reported for solitary fibrous tumor of the pleura, but the same criteria (size, cellularity, mitotic activity, presence of pedicle) were of prognostic significance. The occurrence of solitary fibrous tumor in the mediastinum with the suggestion of thymic origin for some cases, combined with the immunohistochemical and ultrastructural findings, support a mesenchymal origin for this tumor. The differential diagnosis includes spindle cell thymoma, hemangiopericytoma, and peripheral nerve tumors.

Of 18 patients with primary sarcoma of the lung, 10 were women and 8 were men whose ages ranged from 22 to 77 years; 6 patients were in the sixth decade of life. Nine patients had no symptoms referable to the tumor. When present, symptoms were cough, chest pain, or dyspnea. One patient had attacks of hypoglycemia. Radiographically, the tumors were generally large and well circumscribed. Grossly, three tumors were intrabronchial; one of these had invaded the lung. The remaining lesions were intrapulmonary. The sizes of the tumors ranged from 2 to 16 cm in greatest dimension. Histologically, there were nine fibrosarcomas, four leiomyosarcomas, three hemangiopericytomas, and two osteosarcomas. Most of the fibrosarcomas and leiomyosarcomas were poorly differentiated; all hemangiopericytomas were considered malignant, and both osteosarcomas were high grade. Treatment consisted of complete removal when feasible. At last follow-up, four patients were alive without disease from 3 to 18 years after surgery. The common factor in all four of these cases was the size of the tumor, 2 to 3 cm in greatest dimension. Hence, the size of the tumor is the most important prognostic indicator in sarcomas of the lung.

Patients recovering from alcohol and other drug addiction have unique medical and pharmacological needs. Careful selection of medications call decrease the risk of relapse. Angiotensin-converting enzyme inhibitors and calcium channel-blocking medications are excellent choices to treat hypertension. Most gastrointestinal problems resolve with abstinence and can be treated nonpharmacologically. In managing pain, physicians should avoid narcotics and use nonpharmacological treatment whenever possible. Treating recovering patients with HIV can be challenging because of the side effects of many of the antiviral medications. The newer antiviral agents have fewer side effects and contraindications. Commonly used remedies for colds and cough can cause a relapse to drug use. Patients with diabetes mellitus need to be monitored very closely in early recovery to prevent hypoglycemia. Frequently a team approach is helpful in managing the medication needs of patients in recovery.

Fourteen cases (13 pleural and one intrapulmonary) of solitary fibrous tumors (SFTs) (the so-called fibrous mesothelioma) were studied. The lesions occurred more in females (nine cases) than males (five cases). The age of patients ranged from 44 to 73 years old (median 60 years). The tumors presented as cough with or without blood-tinged sputum, exertional dyspnea, chest pain, nausea, body weight loss, fever, or as asymptomatic masses detected by routine chest radiograph. Two patients with huge (tumor larger than 20 cm) malignant tumors had accompanying pleural effusion and one associated with hypoglycemia. Ten benign tumors measured 2-11 cm (median size 7 cm) while the remaining four histologically malignant ones measured 20-30 cm in size. All of them were well circumscribed and thinly encapsulated. Hemorrhage and necrosis were more frequently seen in the malignant tumors. Histologically, these lesions were characterized by 'patternless pattern' with occasional hemangiopericytic features (three cases). The tumor cells were all immunoreactive for vimentin, CD 34, and focally actin-positive in one case, but not for keratin, desmin, S-100 protein, carcinoembryonic antigen, alpha 1-ACT and F VIII-related antigen, supported a primitive mesenchymal origin. p53 protein was expressed in two of the malignant cases. Proliferating cell nuclear antigen stain was positive with 50 and 80% of the labeling index in the benign and malignant tumors, respectively, but retinoblastoma gene protein was negative in all tumors. This analysis confirmed the relationship between histological malignant SFTs and tumor size, cellularity, mitotic activity, necrosis and tumor suppressor gene expression. However, the clinical behavior was unpredictable. Complete respectability seemed to be the most important indicator of clinical outcome in the less aggressive tumors.

Solitary fibrous tumors of the pleura (SFTP) are very rare neoplasms. The majority of these tumors are benign, but about 10-20 % fulfill the criteria of malignancy. The clinical presentation varies according to the size and intrathoracic localization. In early stages, often asymptomatic, the tumors may grow to an enormous size and then cause symptoms such as cough, chest pain and dyspnea, but also paraneoplastic syndromes such as hypoglycemia or digital clubbing. Between 1981 and June 1998 we treated in our institution 16 SFTP in 14 patients (4 M, 10 F, average age at first operation 58 years). Eight patients showed symptoms, whereas in the other cases the tumors were found on routine chest X-rays. The usually pedunculated SFTP were completely resected without complications. Two patients developed malignant recurrences, which infiltrated the right upper lung lobe and the diaphragm respectively. In these cases the tumor was resected together with the adjacent structures. Since late recurrences are more often malignant than primary SFTPs long-term follow-up is mandatory even in benign lesions.

We report two cases of localized benign pleural mesothelioma with different clinical features. Neuropsychiatric symptoms, including coma, hemiplegia, seizures and misbehavior predominated in the first case, associated with hypoglycemia. The symptoms in the second case were essentially respiratory (cough, dyspnea, and chest pain). Treatment consisted in thoracotomy and complete surgical resection. Histopathology revealed fusiform cells and collagen stroma. These two cases illustrate the diversity of clinical expression of benign localized pleural mesothelioma and confirm their complete resolution after surgical treatment.
