Many reports dealing with the toxicity of oil mist in industrial health have been published. The condition appears to be worldwide in distribution and the number of reported cases increases with increasing clinical awareness. In 158 reports published from 1965 to 1993 the following diseases were observed: Skin--contact dermatitis, oil acne and photosensitive allergic dermatitis; Scrotum--benign and malignant tumors; Respiratory system-nasal discomfort symptoms, rhinitis, nasal mucosal dysplasia, nasal mucosal tumor, laryngeal cancer, bronchitis, lipoid pneumonia, lung fibrosis, lung cancer and bronchial asthma; Others--possible carcinogenicity, high incidence of chromosomal change. This shows that oil mist appears to be involved in many industrial diseases, however, cause-and-effect relationship still remains a matter of conjecture; in which exposure dose and/or duration-dependent toxicity is highly probable. Further investigations will be required including immunotoxicological as well as environmental studies for oil mist exposure.

A 65-year-old woman was admitted to our hospital because of pulmonary nodules, about 3 cm in diameter in the right upper lobe accompanied by pleural indentation, and 5 mm in diameter in the left middle lung field, revealed by chest X-ray. She had no clinical signs or symptoms except achalasia-like discomfort swallowing. Results of physical examinations were within normal limits. A specimen obtained from the nodule in right S2 by transbronchial biopsy showed noncaseating epithelioid granuloma containing asteroid bodies, and negative staining for acid-fast bacilli. No malignant cells were found in the specimen. Bacteriological examination of a bronchial lavage specimen was negative for pyogenic bacteria, mycobacteria and fungi. A PPD skin test was negative. BALF revealed an increase of lymphocytes and elevation of CD4/CD8 ratio. Fifteen years previously, the patient had been diagnosed as having sarcoidosis by scalene node biopsy, and had been treated with steroid therapy. Pulmonary nodules associated with pleural indentation in sarcoidosis is relatively rare, and is usually due to malignancy such as lung cancer. This possibility was ruled out clinically in the present case. Therefore, it was concluded that the pulmonary nodules in this case were due to the sarcoidosis itself.

A 85-year-old female was admitted with general fatigue and chest discomfort in July 1991. Her chest X-ray film showed several pulmonary nodules in the bilateral lung fields without hilar lymphadenopathy. Metastatic lung cancer was suspected, but primary cancer was not detected in spite of cancer screening. Hemoglobin was 8.7 g/dl. The patient also had various immunological abnormalities including increased serum cold agglutinin titer, decreased serum complement, positive anti-nuclear antigen and IgM-kappa monoclonal gammopathy detected by immunoelectrophoresis. She was diagnosed as having autoimmune hemolytic anemia with cold agglutinin disease and M-protein. With the administration of corticosteroids, hemolytic anemia improved temporarily, but the patient died of hemorrhagic gastritis. At autopsy, a lung tumor was detected in the left upper lobe, mainly without hilar lymphadenopathy. The autopsy specimens showed Non-Hodgkin's lymphoma (diffuse medium-sized cell type), differentiated from macroglobulinemia by immunohistochemical studies. In elderly patients, with various immunological abnormalities, B-cell lymphoproliferative disorders such as malignant lymphoma should be suspected.

Thoracoscopy has been around for decades, advocated by some, but until recently, ignored by many. Not surprisingly, its diagnostic and therapeutic efficacy in patients with suspected or proven malignant pleural effusions has withstood the test of time. Today, the potential benefits of thoracoscopy must be weighed against its cost in patients with limited life expectancy. Although diagnostic thoracoscopy requires only overnight hospitalization, pleurodesis imposes a longer hospital stay. The discomfort of an indwelling chest tube, the need for hospitalization, and the financial burden of thoracoscopic procedures compared with less-invasive means of pleural investigation and pleurodesis must be taken into account on an individual basis. Thoracoscopy should not be performed for the sake of intervention. Its indications and all diagnostic or therapeutic alternatives should always be carefully examined. Its role, however, in the diagnosis and treatment of patients with malignant pleural effusions is undeniable. The diagnostic accuracy of thoracoscopic pleural biopsy is excellent. Several studies demonstrate that thoracoscopic talc pleurodesis is more frequently successful than other methods of pleurodesis. As a staging procedure, thoracoscopy helps determine extent of disease, and possibly, prognosis in patients with metastatic pleural carcinomatosis, lung cancer, and malignant mesothelioma. As this procedure is increasingly rediscovered by our medical and surgical communities, greater clinical and experimental investigation aimed at establishing successful management strategies in patients with malignant pleural effusions will hopefully occur.

The best treatment for inoperable "non small cell" lung cancer remains unknown. While metastatic patients are usually treated palliatively, the therapeutic course for locally advanced disease is less clear cut and more controversial. The common habit was been to treat these patients only when disturbing symptoms are present. But this is now changing, because defined radiotherapy techniques and combinations with chemotherapy and/or radiosensitizers produce better results. Also, in palliative treatments new dose-fractionalised schemes are being sought, with the aim of less discomfort and better efficacy. Two clinical trials are presented. The first is a palliative, 10 Gy single-dose treatment of 17 patients with chest symptoms. Results have been encouraging: 67% symptoms palliated at 1 month from treatment. Palliation was however short: 42% at 2 months, 32% at 3 months. The low incidence and mildness of acute complications in this small number of patients permit us to conclude that the treatment is feasible and tolerable; short-lived palliation could be used in patients with a short life expectancy. In the second study, was a multimodality treatment-polychemotherapy (Cisplatin 100 mg/mq days 1, 22 and Vinblastine 5 mg/mq days 1, 8, 15, 22) followed by radiotherapy (60 Gy/30 fractions/42 days) with Cisplatin (5 mg/mq/d) as a radiosensitizer. 15 patients have been recruited, but only 7 could be evaluated. 5/7 objective responses were observed (3 complete). Whole acute toxicity is acceptable. The lack of data concerning late toxicity does not allow conclusions about the feasibility of this therapeutic.

Lesbians may engage in behavior that places their health at risk and may delay health care and screening more than do their heterosexual counterparts. This article examines influences on lesbians' health risk factors and health-seeking behaviors. A statewide, self-administered survey of members of a lesbian community organization was performed. Univariate and bivariate analyses were calculated, and linear regression was used to examine models of health risks and health-seeking behavior. Of 324 respondents, 90% had disclosed sexual orientation to at least one provider, 22% reported seeking care without symptoms (preventive care), and 23% reported waiting until symptoms are at their worst or never seeking care. Young age, belief in the importance of lung cancer, difficulty of getting health care when needed, reliance on the partner for health support, and fewer male partners were all associated with greater health risk for lesbians. Difficulty obtaining health care, difficulty communicating with the primary care provider, discomfort in discussing depression, and degree of comfort in discussing menopause were all associated with a delay in seeking health care. Sensitive communication with lesbians and further identification of lesbians' specific barriers to care may improve health-seeking behavior and provide more opportunities for screening and risk factor counseling in this population.

To determine the diagnostic efficacy of thoracoscopic fine-needle aspiration (FNA) of solitary pulmonary nodules suspicious for lung cancer, we performed intraoperative thoracoscopic FNA for diagnostic purposes in 8 consecutive patients with peripheral solitary pulmonary nodules suspicious for lung cancer. Thoracoscopic FNA yielded an accurate diagnosis in all cases. There were 5 cases of non-small cell lung carcinoma, 1 small cell lung carcinoma, 1 renal carcinoma metastasis, and 1 inflammatory nodule. Results of FNA were obtained in less than 10 minutes in 6 cases. Maximum time to diagnosis was 20 minutes. The surgical procedure was expedited in the 6 cases of lung cancer because lobectomy followed FNA rather than the performance of a diagnostic wedge resection. A minor hematoma after FNA was the single complication. Thoracoscopic FNA yielded a prompt and accurate diagnosis of peripheral solitary pulmonary nodules. Thoracoscopic FNA should be considered as an alternative to preoperative percutaneous FNA, which risks pneumothorax and patient discomfort. In cases of lung cancer, thoracoscopic FNA allows the surgeon to bypass a diagnostic wedge resection and to proceed with definitive lobectomy.

Colorectal cancer is the third most common non-skin malignancy in women, after breast and lung cancer. Although approximately 40% of the 65,000 women diagnosed each year eventually die of the disease, colon cancer is highly curable when diagnosed at an early stage. Moreover, because the majority of colon cancers arise in previously benign colonic polyps, there is a substantial period, up to several years, in which removal of polyps can reduce the risk of colon cancer. Recently, the United States Preventive Task Force recommended universal screening for colon cancer after age 50. Strong evidence from randomized controlled trials and case-control studies supports use of annual testing for occult blood in stool and flexible sigmoidoscopy every 5-7 years. Although the risk of colon cancer is similar in men and women, women frequently have the perception that colorectal cancer is a man's disease. Partially in consequence, women are less likely than men to undergo screening sigmoidoscopy. Further barriers include primary care providers' lack of awareness of updated guidelines and patients' lack of compliance with multiple screening tests and their fear of discomfort. Because the risk of colorectal cancer can be reduced by up to 75% in those who undergo screening and subsequent surveillance to remove further polyps, it is crucial that women be targeted to undergo screening tests for colorectal cancer.

Myocardial involvement by malignant neoplasm is rare and often not clinically manifested. The diagnosis is usually made only at autopsy. A 71-year-old man with squamous cell lung cancer presented with chest discomfort. His electrocardiogram was diagnostic of acute myocardial infarction. However, because of the lack of classic symptoms and signs of acute myocardial infarction and normal serum levels of cardiac enzymes, an echocardiography was performed before initiation of thrombolytic therapy. The echocardiography showed a huge hyperechoic mass located in the posterolateral aspect of the left ventricle with myocardium invasion. Thrombolytic therapy was withheld. In patients with lung cancer, an electrocardiogram representative of acute myocardial infarction can rarely be induced by myocardial involvement with lung cancer.

Morbidity, mortality and discomfort related to gastrectomy has led some investigators to treat patients with stage I-II primary gastric high-grade lymphoma (PGL) with a conservative strategy. Here we report a retrospective series of 21 patients with PGL treated with primary chemotherapy alone or followed by radiation therapy and analyze previously reported series, focusing on therapeutic results, treatment-related morbidity and stomach preservation rate. All 21 patients with stage I-II PGL received an initial anthracycline-containing chemotherapy, which was followed by involved field-radiation therapy in 8 cases. Data regarding toxicity, response and relapse rates and survival of this patient group and 14 previously published series, involving 316 patients treated with conservative modality, were also analyzed. In the present series two patients did not complete the planned treatment, while the remaining 19 achieved a complete remission (response rate: 90%). Three patients relapsed, all of whom had been treated with chemotherapy alone. Two patients died of lymphoma, one of sepsis and the other of lung cancer while still relapse-free. The survival rate at 50 months is 81%, and the 5-year actuarial cause-specific survival is 82%. The stomach preservation rate is 100%. Previously reported series showed a response rate ranged between 76% and 100%. Gastrointestinal bleeding was observed in only 3% of cases, while no cases of gastric perforation were reported. Treatment mortality rate was 2.5%. 5-year actuarial survival ranged between 73% and 90% and stomach preservation rate was 97%. Short-term chemotherapy obtained similar results to more prolonged treatment. In conclusion, conservative treatment with primary chemotherapy followed by involved field-radiation therapy should be used for the first-line treatment of patients with stage I/II PGL considering that it is associated with a high response and survival rates, and with an insignificant risk of bleeding or perforation, high stomach preservation rate and good quality of life.
