1/550. Baker's asthma due to the enzyme xylanase -- a new occupational allergen.The asthmatic baker showed IgE-mediated sensitization to xylanase of aspergillus niger used as a baking additive. Inhalative challenge with approximately 0.5 microg of the enzyme resulted in an immediate-type asthmatic reaction. This case, as well as a preliminary screening of symptomatic bakers, shows that xylanase is a further relevant type I-sensitizer in the baking industry.- - - - - - - - - - ranking = 1keywords = ill (Clic here for more details about this article) |
2/550. Fatal and non-fatal injuries from vessels under air pressure in construction.Using a surveillance system that captures data on construction workers treated in an urban emergency department, we identified a series of injuries caused by vessels and tools under air pressure. We describe those six cases, as well as similar cases found in the Census of Fatal occupational injuries; we also review data from the National Surveillance for Traumatic Occupational Fatalities database and data from the Bureau of Labor statistics. Among the injuries and deaths for which we had good case descriptions, the majority would have been prevented by adherence to existing Occupational safety and Health Administration standards in the construction industry.- - - - - - - - - - ranking = 2keywords = ill (Clic here for more details about this article) |
3/550. blastomycosis acquired occupationally during prairie dog relocation--colorado, 1998.On August 31, 1998, two suspected cases of fungal pneumonia were reported to the Boulder County (colorado) Health Department (BCHD). Both patients were immunocompetent, otherwise healthy adults working for the City of Boulder Open Space (CBOS) program on a prairie dog relocation project. This report summarizes the epidemiologic investigation by BCHD, the colorado Department of public health and environment, and CDC; the findings indicate that these two persons acquired blastomycosis in colorado, which is outside the area where the disease is endemic.- - - - - - - - - - ranking = 376.20768285073keywords = person (Clic here for more details about this article) |
4/550. carpal tunnel syndrome: is it work-related?The reported incidence of work-related carpal tunnel syndrome has skyrocketed; however, many cases have an underlying systemic cause. A methodical investigation--including appropriate imaging studies and laboratory testing--can differentiate symptoms that are primarily occupational from those with associated medical illness or obesity.- - - - - - - - - - ranking = 41.350368554955keywords = illness, ill (Clic here for more details about this article) |
5/550. radium-induced malignant tumors of the mastoid and paranasal sinuses.In the records of 5,058 persons with therapeutic or occupational exposure to radium, 21 patients with carcinoma of the mastoid and 11 with malignant tumors of the paranasal sinuses were identified. Tumor induction times were 21-50 years for mastoid tumors (median, 33) and 19-52 years for paranasal sinus tumors (median, 34). Dosimetric data are given for the patients whose body burdens of radium have been measured. We found a high proportion of mucoepidermoid carcinoma, comprising 38% of the mastoid and 36% of the paranasal sinus tumors. Three patients had antecedent bone sarcoma at 20, 11, and 5 years, respectively, and a bone sarcoma was discovered at autopsy in a fourth patient. Radiographic changes in the mastoid and paranasal sinuses were similar to those seen in nonradium malignant tumors. More than 800 known persons exposed to radium before 1930 and another group of unknown size who received radium water or injections of radium from physicians are still alive and at risk of developing malignant tumors of the mastoid and paranasal sinuses.- - - - - - - - - - ranking = 753.41536570145keywords = person, ill (Clic here for more details about this article) |
6/550. inhalation anthrax in a home craftsman.inhalation anthrax with complicating subarachnoid hemorrhage due to simultaneous infection with two capsular biotypes of bacillus anthracis of different virulence for the mouse is reported.

7/550. A unique case of vibroacoustic disease: a tribute to an extraordinary patient.This paper describes the case of a patient, Mr. A, who died in 1987. The information provided by Mr. A in life, and his insistence on making a will demanding an autopsy on his death, has given us invaluable data on Vibroacoustic disease (VAD). Mr. A was an intellectually curious man who researched the medical literature related to his condition, and compared it to his own experience. He would describe all his sensations during his many epileptic seizures. Solely because of the results of Mr. A's autopsy, new avenues of research were initiated. These have led to new concepts and exciting new perspectives on noise-induced extraaural pathology. VAD is today a well-established and easily diagnosed entity. This paper is a tribute to Mr. A, in whose honor we have an on-going commitment to establish VAD as an occupational disease, reimbursable by Worker's Compensation.- - - - - - - - - - ranking = 1keywords = ill (Clic here for more details about this article) |
8/550. epilepsy in the vibroacoustic disease: a case report.INTRODUCTION: Late-onset epilepsy was one of the first neurological problems identified in patients diagnosed with vibroacoustic disease. Other clinical situations, such as automatisms and rage-like reaction crises were also observed. Some cases of epileptic seizures were triggered by different types of stimuli. CASE REPORT: This study describes the clinical case of a 30-yr-old male metal-worker who had epileptic seizures when he used vibratory tools common to his profession, such as drills and sanders. We performed a 21-channel EEG during a seizure induced in the laboratory by direct contact of a vibratory tool with his right hand. This allowed us to view the electrical discharge of his left hemisphere. The entire procedure was simultaneously videotaped while a partial motor crisis was observed. brain MRI of this subject revealed multiple hyperintense focal lesions in the sub-cortical white matter. echocardiography revealed thickening of the pericardium and valve structures. COMMENTARY: To the authors' knowledge, this is the first documented case of reflex epilepsy due to vibratory stimuli. We briefly discuss the possible pathophysiological mechanisms of this clinical event.- - - - - - - - - - ranking = 1keywords = ill (Clic here for more details about this article) |
9/550. Outbreak of Hendra-like virus--malaysia and singapore, 1998-1999.During September 29, 1998-April 4, 1999, 229 cases of febrile encephalitis (111 [48%] fatal) were reported to the Malaysian Ministry of Health (MOH). During March 13-19, 1999, nine cases of similar encephalitic illnesses (one fatal) and two cases of respiratory illness occurred among abattoir workers in singapore. Tissue culture isolation identified a previously unknown infectious agent from ill patients. This report summarizes the preliminary epidemiologic and laboratory investigations of these cases, which indicate that a previously unrecognized paramyxovirus related to, but distinct from, the Australian hendra virus is associated with this outbreak.- - - - - - - - - - ranking = 83.70073710991keywords = illness, ill (Clic here for more details about this article) |
10/550. Occupational IgE-mediated asthma, rhinoconjunctivitis, and contact urticaria caused by Easter lily (lilium longiflorum) and tulip.BACKGROUND: We report on IgE-mediated asthma, rhinoconjunctivitis, and contact urticaria to two liliaceae plants, tulip and Easter lily (lilium longiflorum), diagnosed in a floral shop worker. methods: Occupational asthma was diagnosed according to patient history, PEF monitoring, and a work-simulating provocation test. Flower-specific IgE was studied, and RAST inhibition tests were performed. RESULTS: skin prick testing showed positive reactions to tulip, Easter lily, and chrysanthemum. Total IgE was 180 kU/I, and specific IgE to tulip was 2.6 and to Easter lily 6.5 kU/I. In the RAST-inhibition test, no cross-reactivity was found. Occupational asthma was diagnosed by peak flow monitoring at work and at home, as well as specific inhalation challenge with Easter lily, with an immediate 18% reduction in PEF. In addition, contact urticaria and conjunctivitis were diagnosed. After a 9-year follow-up without exposure to lilies, the skin prick tests to L. longiflorum and tulip were still positive, but the specific IgE had disappeared. CONCLUSIONS: A case of IgE-mediated occupational asthma, rhinoconjunctivitis, and contact urticaria caused by L. longiflorum and tulip is presented. RAST inhibition tests indicated concomitant sensitization to the two liliaceae plants.- - - - - - - - - - ranking = 1keywords = ill (Clic here for more details about this article) |
