1/8. Ornithonyssus (acari: Macronyssidae) mite dermatitis in poultry field-workers in Almarg, Qalyobiya governorate.Cutaneous manifestations of bird and rat mite infestation in man are not easily recognized by physicians or patients. Clinical signs and symptoms are developed secondary to bites of mites that have infested rats, domestic poultry or birds nesting in or near human habitation and comes into contact with man. This study details 4 cases of pruritic dermatitis developed in four field workers in poultry farms in Al-Marg district, Qalyobia governorate, egypt. The zoonotic species of Ornithoyssus sp., (family Macronyssidae) was isolated from all samples collected from patients' habitat and the role played by Ornithonyssus mites in causing dermatitis in man was discussed.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/8. Practice-based agromedicine: the need for client-centered research.During recent years, several client calls received from Clemson University Cooperative Extension Service office and private physicians have required client-oriented investigations. These have practical implications for preventive medicine and public service. The challenges for differential diagnosis across disciplines are not for the faint-of-heart or the narrow thinking specialist. Examples of incidents that have signaled a problem and resulting research projects are: 1) anaphylactic cardiovascular response to red imported fire ant venom (statewide morbidity survey); (2) unexplained contact dermatitis in tomato harvesters and floral designers (immunodermatologic study and statewide survey of florists); (3) concerns over two unexplained cancer deaths at an experimental agricultural research station (farmer's mortality study); (4) a household outbreak of organophosphate poisoning (statewide hospital morbidity survey); and (5) a woman in early pregnancy exposed to misapplication of chlordane in her house (literature review and update on trends in U.S. birth defects). These examples reflect a broad but responsive interdisciplinary approach to the needs of the clients of the south carolina Agromedicine Program.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/8. Mechanical cornpicker hand injuries.The mechanical cornpicker causes tearing anse injuries from 1962 to 1975 were studied with regard to mechanism and extent ohe time of injury in 36% of hands, and in 73% of the remainder following treatmophylaxis, and antibiotics, and 73% hands required some form of delayed surgical treatment. Antibiotics did not appear to be helpful. Eighty-nine ps the most common cause given for farmers for their injuries. Excluding four pr permanently disabled patients, the average length of disability was 135 days. Eighty-nine per cent of patients experienced some permanent impairment of hand function. The mechanical cornpicker is described, and the importance of its proper use and physician's emphasis on accident prevention as well as treatment are stressed.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/8. Chemical carcinogenesis. A soil fumigant, 1,3-dichloropropene, as possible cause of hematologic malignancies.Findings from three case reports suggest a causal relationship between exposure to a soil fumigant , 1,3- dichloropropene , and hematologic malignancy. Its chemical relationship to other carcinogens is noted. The purpose of this report is to record this evidence and alert physicians that prior exposure to this chemical of patients initially observed with neoplasms should be noted in the medical history.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/8. Orf occurring in missouri.We report two cases of orf, a common viral disease of sheep, which occurred in residents of missouri. A survey taken among sheep raisers in missouri revealed that many were unaware of this as a potential human disease. It is important for physicians to be able to recognize this lesion so that radical methods of therapy are not employed. The lesion heals without scarring and without specific therapy. Complications are rare.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
6/8. Chronic health effects among sheep and humans surviving an aldicarb poisoning incident.aldicarb is a granular carbamate insecticide, acaricide and nematocide applied to soil. In 1989, a large scale aldicarb poisoning of grazing sheep occurred in south central washington State. Among 1600 animals in 3 different groups, 288 of 318 sheep in 1 group died within a very short time. An investigation by the washington State Department of agriculture concluded that aldicarb poisoning was the cause of the acute sheep deaths. Within 3 w of the incident, all the 30 sheep which survived the initial exposure from the 1 group had died or were near death and euthanized. Among the approximately 1300 sheep nearby but not affected by the acute incident, low fertility and poor health were apparent over the next 3 y. These sheep also suffered more deaths than expected, and lambs born to the sheep had a higher frequency of limb and gastrointestinal malformations than usual. All of the 6 men present in the field the day of the acute sheep deaths complained of acute symptoms. Three men were hospitalized the night of the sheep deaths and 2 were seen by a physician the next day. All men were healthy prior to the sheep deaths. Within a few days 4 of the 6 men developed a productive cough and 1 reported right-sided abdominal pain. Three years after the incident 5 of the men were still seeking medical attention or reporting symptoms they felt associated with the acute exposure. The chronic health effects in the sheep and men are not expected following exposure to aldicarb. No explanation exists for the chronic health effects, nor have such effects been previously reported in aldicarb poisonings.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
7/8. The pesticide-exposed worker: an approach to the office evaluation.BACKGROUND: Pesticide exposures have clinical, epidemiological, legal, and political ramifications that go beyond the confines of a physician's office. The examination of the employee who has been exposed to a pesticide should be undertaken in an organized and methodical manner so that specific questions of causality can be answered and treatment can be initiated. methods: Five representative case studies illustrate different circumstances in which a pesticide injury can be seen in the office setting. RESULTS AND CONCLUSIONS: A wide range of pesticides is used in business and home, and the dangers of misdiagnosis, maldiagnosis, underdiagnosis, and overdiagnosis are especially common given the variety of chemicals used. The exposed employee must be removed from the source of exposure. Complete decontamination is a primary concern, and patients with unstable vital signs will need to be hospitalized. A methodical office examination, however, can be carried out on many exposed employees. A detailed description of the circumstances of the exposure should be elicited, and the chemical implicated in the exposure should be researched. A pesticide exposure is a sentinel event in the life of a patient and also suggests that other employees can be exposed. Such an exposure needs to be carefully assessed and documented, and proper treatment must be rendered. Further, the exposure can represent the first of many other exposures that might or might not be reported. Proper notification of authorities can limit exposures before they become severe.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
8/8. Occupational asthma in greenhouse tomato growing.An employee working in a commercial tomato growing greenhouse developed asthma of increasing severity over a period of 8 years. She was diagnosed as having occupational asthma by a chest physician. The cause was obscure and initial allergy testing was negative. Further investigation of the workplace gave rise to suspicion of allergy to insects. Immunological testing confirmed sensitization to Red Spider Mite.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
