A report from Kampala, Uganda, compares the situation in 1991 to the state of chaos 10 years earlier when the regime of Idi Amin had been overthrown by Milton Obote's soldiers with the help of Tanzanian troops. Soldiers went on looting sprees, and 1 victim of their marauding became a 12-year old boy who got shot for refusing to part with his bike. In contrast, in 1991 things were much more peaceful; however, the AIDS epidemic was the new threat. The government radio transmits hourly warnings on HIV. Since President Museveni came to power, economy and security have improved radically. Shops and markets are open until late at night; public transport is reliable, and small scale industry flourished. There would be optimism about the future, if AIDS was not here. There is no doubt that the economy will soon be affected. According to the Kampala blood bank, 40% of the healthy population is already seropositive. In the hospitals the majority of admissions suffer from AIDS with diarrhea and an itching dermatitis; there is more cancer of the cervix and lymphoma; appendicitis is on the increase; and tuberculous lymph nodes are now quite common. Many of these patients have clinical AIDS. The government is frank about the situation and is active in preventive measures and education. Private charities and foreign aid organizations contribute. But the epidemic is so overwhelming, that some Western organizations might soon lose interest owning to meager returns on their efforts. A 6-year-old boy has grossly swollen lymph nodes around his neck, both parotids are painfully swollen, pus pours from the ears. A nonspecific cough and mild diarrhea are also present with an itching and sore herpes zoster on his left chest. the mother is frightened of losing him, and demurs at the hint of AIDS, since for her, AIDS means sexual promiscuity.

The involvement of the pulmonary vessels by tumour emboli may lead to a clinical picture defined as 'subacute cor pulmonale'. Information about this syndrome has been limited to case reports and a few series. A study of 214 autopsied cancer patients was undertaken to investigate the clinical signs and symptoms of tumour involvement of the pulmonary vessels (TIPV). The lungs were removed as a block and 15 sections (3 from each lobe) were analyzed. Clinical data about right ventricular failure, dyspnoea, cough, pleuritic chest pain, cyanosis, engorgement of jugular veins, peripheral oedema, haemoptysis and haemoptoic sputum were obtained from the medical records of each patient. Tumour emboli were detected in 89 cases, and no respiratory symptoms were recorded in 39. The presence of dyspnoea and cyanosis were highly significant in the group with TIVP, and right ventricular failure and peripheral oedema showed slight significant differences between the patients with and without TIPV. The classical picture of subacute cor pulmonale was observed in 13 patients and TIPV was considered to be the main cause of death in 29 cases. Our results indicate that although the development of subacute cor pulmonale was rare in patients with cancer, TIPV may be suspected when the patient presents respiratory distress and should be included in the differential diagnosis of dyspnoea in cancer patients.

Pneumocystis carinii pneumonitis (PCP) can occur in immunocompromised hosts, especially AIDS and cancer patients. Although recent research has focused on PCP in AIDS patients, few studies have described the clinical presentation of PCP in recipients of bone marrow transplantation (BMT). Between 1976 and 1991, of 1454 BMT patients at the University of Minnesota, PCP was documented in only 19. Eighteen of these had not been receiving PCP prophylaxis. Patients presented with a brief period (2-10 days) of symptoms including dyspnea, cough, and fever in greater than 75% of patients, but had only scant abnormal physical findings. Chest X-rays showed bilateral infiltrates in 58% of all patients, though 15% had no or minimal X-ray findings. Bronchoscopic alveolar lavage confirmed the diagnosis most often, but 13% of lavages were negative and required biopsy for the diagnosis. High dose trimethoprim-sulfamethoxazole was the initial treatment for 84% of the patients though 25% of these patients were later switched to pentamidine due to poor response or hypersensitivity reactions. Despite prompt diagnosis and therapy, overall survival was poor, with only 37% of patients surviving pneumonitis. Patients developing PCP less than 6 months post-BMT had greater mortality (89%) versus only 40% in later onset PCP (p less than 0.0001). Despite this better survival in the late-onset PCP cohort, the development of pneumonitis in these patients underscores the necessity for continued PCP prophylaxis beyond 1 year in some patients. Ongoing immunocompromise and need for prophylaxis should be appreciated in patients with graft-versus-host disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-eight workers from a factory producing nickel-cadmium and other types of batteries came to us for medical evaluation. They included 21 women and 17 men (seniority 2-20 years, age range 31-63 years), and represented a self-selected subset of 700-900 ever-employed and 200+ recently or currently employed workers in the factory. Thirty-four worked on the nickel-cadmium assembly line. Symptoms and signs included: headache in 34; weakness, fatigue and lassitude in 26; dizziness in 16; pruritus and skin eruptions in 37; gingivitis, teeth loss and caries in 34; nasal congestion, nosebleeds and anosmia in 30; cough, phlegm production, wheezing and shortness of breath in 26; "asthma" in 14; bone pain in 18; urinary frequency, beta 2 microglobulinuria and kidney stones in 17; and sterility or multiple abortions (33) in 8 of 21 women. One additional patient had died from an "amyotrophic lateral sclerosis-like syndrome", while CT scans in six workers revealed brain atrophy. One other worker had leukemia, and two had died from cancer (lung and pancreas). Those who had worked for more than 10 years had more symptoms and signs than shorter-term employees, especially neurological illness, bone pain and urinary tract problems, including beta 2 microglobulinuria. Past blood and urinary cadmium levels were in the range of 1.6-8.7 micrograms/dl and 8-306 micrograms/l, respectively. Our findings indicated that: a) health risks for workers were not confined to the nickel-cadmium assembly line or to older workers, b) hazardous exposures still existed and illness appeared in new workers after a clean-up and intervention program, and c) exposures involved increased risks for renal disease and cancers. Finally, there is a need to control exposures and determine health risks in the full cohort of those ever employed, in the workers' children, and in the surrounding environment (air, ground, water) due to the dumping of waste from the plant.

The authors report the clinical features of hypersensitivity reactions believed to result from procarbazine in eight patients treated with mechlorethamine, vincristine, and procarbazine (MOP) for high-grade glioma. There was one instance of hypersensitivity in 7 patients treated for recurrent disease and seven instances in 16 patients treated with an adjuvant protocol using MOP directly after surgery. Maculopapular rash was seen in seven of eight, fever was seen in four of eight, and reversible abnormal liver function test results were seen in three of four patients. Pulmonary toxic effects were seen in five of eight patients and consisted of isolated interstitial pneumonitis in one, fever and infiltrate after rechallenge with procarbazine after previous rash in two, and cough accompanying rash in two. The toxic effects were mild to moderate in six patients but severe to life threatening in the two who were rechallenged after development of rash. The observed incidence of rash during adjuvant therapy was higher than that previously found by the authors for recurrent disease, and it appears to be higher than has been reported in Hodgkin's disease, lymphoma, and other solid tumors. The findings by the authors suggest that a high index of suspicion be kept for hypersensitivity reactions to procarbazine when treating primary brain tumors and that, contrary to the experience in other settings, procarbazine be stopped if rash develops.

Primary neoplasms of the trachea are much less common than malignancies of the larynx and lungs. Tracheal neoplasms account for less than 0.1 percent of all neoplasms. Their importance lies in the fact that they may initially be misdiagnosed, resulting in a delay in diagnosis ranging from months to years. The most common benign tracheal neoplasms are hemangiomas, squamous papillomas and fibromas. The most common tracheal malignancy is squamous cell carcinoma. Symptoms of these lesions are usually related to airway obstruction and include wheezing, dyspnea and cough.

There were 79 cases of cardiac tumors seen from 1957 to July 1988. 49 (62.0%) of them were benign and 30 (38.0%) malignant. All the 49 benign tumors except 2 were surgically excised and found to be myxoma. Of them, 18 patients were male and 31 female. 85.7% of the tumors were located in the left atrium, 12.2% in the right atrium and 2.0% in the left ventricle. Palpitation, dyspnea, chest oppression, fever, episodes of syncope and hemiplegia, cough, diastolic and systolic murmurs at the apical or tricuspid area were the common symptoms and signs. Atrial fibrillation was found only in 2 cases. Echocardiographic findings were diagnostic while ECG and X-ray findings were nonspecific. Four patients died after operation. Of the 30 cases of malignant tumors, 15 were secondary tumors metastasized mainly from the lung or mediastinal malignancies. Of 11 primary tumor cases (7 males and 4 females), 3 were malignant lymphoma, 2 mesothelioma of pericardium, 2 malignant myxoma, 1 angiosarcoma, 1 leiomyosarcoma, 1 fibrosarcoma and 1 rhabdomyosarcoma. Another 4 cases were not studied histopathologically. The clinical manifestations, ECG and X-ray findings of the 11 primary tumors were nonspecific but echocardiography was helpful to the diagnosis. Six patients were operated on and 1 died during hospitalization.

We examined 135 elderly patients with pneumonia to clarify the factors predicting on the outcomes of the elderly pneumonic patients. In the fatal cases respiratory symptoms such as cough and sputum, except for dyspnea were less frequent but pulmonary infiltrations on chest roentgenograms were more massive as compared with those in the survived cases. Thus, it was suggested that in the fatal cases the more advanced pneumonia had developed at the time when the diagnosis of pneumonia was made. The fatal cases showed hypoalbuminemia, hypocholesterolemia and hyponatlemia more frequently as compared with survived cases. Among these laboratory values, the decreased serum albumin concentration seemed to be most closely correlated with the fatal outcome of the elderly pneumonic patients. There were significant differences in the outcomes among three groups of the patients, those who were the prolonged bed-ridden, those with severe underlying diseases such as cancer and those treated as out-patients. The out patients showed the most favorable outcome and the prolonged bed-ridden patients the worst outcome. Approximately, 39% of the fatal cases were complicated with multiple organ failure. These results suggest that more important factors which affect the outcomes of pneumonia in the elderly may be not merely aging but the conditions of the host at onset of the disease.

Sixty-one patients underwent operations for malignant thymomas between 1961 and 1989. Twenty-three patients had associated myasthenia gravis (MG), an incidence of 37.7%. Upon being admitted to the hospital, the patients' most common symptoms included chest pain, MG, cough, and dyspnea. Only 7 of 61 (11.5%) patients had no symptom. Tumor staging of 58 patients with invasive thymomas was performed according to Masaoka classification. The patients were classified as follows: Stage II disease, 5; Stage III, 41; Stage IVa, 8; and Stage IVb, 4. In addition, thymic carcinoma was present in three patients. The series had a resection rate of 55.7%. The incidence of operative complications was 16.3%. Only one patient died of myocardial infarction; the incidence of operative mortality was 1.6%. The patients with MG had a higher rate of resection (69.6%) and a higher incidence of complete thymectomy (14 of 23 patients; 60.9%). Mixed lymphoepithelial tumors and epithelial cell predominant tumors were the most frequent histologic patterns (45.9% and 34.4%, respectively). Fifty-two patients had postoperative radiation therapy, and 10 patients had chemotherapy. The overall cumulative survival rates in the series were 59% and 34% at 5 and 10 years, respectively. The results demonstrated that the factors affecting the prognosis may include resectability, postoperative irradiation or chemotherapy, MG, and tumor staging. The influence of histologic variation on survival rates could not be clearly defined in the series. Surgical resection, particularly complete thymectomy, followed by irradiation is the primary option of therapeutic management for malignant thymoma.

A 78-year-old man was admitted to our hospital with cough and left anterior chest pain. Chest X-ray examination on admission revealed a tumor shadow in the left upper lobe. Malignant tumor cells were observed on histopathological examination of a specimen obtained by bronchoscopic biopsy. Radiotherapy was performed but was not effective, and the patient died of respiratory failure 4 months after admission. Autopsy revealed a 15 cm diameter tumor with marked local invasion tendency without distant metastasis. Microscopically, the tumor consisted partly of squamous cell carcinomas, and partly of fibrosarcomas, composed of spindle cells and osteo-chondrosarcoma. The tumor was therefore diagnosed as carcinosarcoma. Immunohistochemical examination showed positive keratin and EMA staining only in the squamous cell carcinoma component of the tumor.
