1/13. Unusual cause of hematuria.The leech is an invertebrate which has the habit of entering the anatomical orifices of man and animals. During the process of sucking blood it releases an anticoagulant and causes continuous bleeding from the bite site. A leech as a cause of gross hematuria is unusual. We present a case of a leech in the bladder as a cause of gross hematuria.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
2/13. erysipelothrix rhusiopathiae endocarditis: a preventable zoonosis?BACKGROUND: erysipelothrix rhusiopathiae is a bacterium ubiquitous in the environment. It can cause a variety of diseases and the risk of infection is closely related to the level of occupational exposure to infected or colonised animals. AIMS: To discuss the clinical features and treatment of this zoonosis, to increase awareness of this pathogen and to emphasise the need for meticulous attention to hygienic work practices in reducing the risk of infection. METHOD: A case report of a farmer with E. rhusiopathiae endocarditis and the management of the infection. RESULTS: The patient was successfully treated with valve replacement surgery and antimicrobial therapy. CONCLUSIONS: Early identification of this microorganism is essential for appropriate treatment of endocarditis. Greater awareness and safe work practices can help reduce the risk of human infection by this microorganism.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
3/13. brucella osteomyelitis of the proximal tibia: a case report.brucellosis is a disease of domestic and wild animals that is transmittable to humans. Although endemic in some parts of the world, brucellosis is an uncommon human pathogen in the united states. The clinical presentation of brucellosis is nonspecific, and brucella osteomyelitis can produce lytic lesions on radiographs that resemble neoplasm. diagnosis can therefore be difficult unless a high index of suspicion is maintained. We present a case of brucella osteomyelitis of the proximal tibia that demonstrates these features.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
4/13. Pseudo-delusory syndrome caused by Limothrips cerealium.BACKGROUND: Limothrips cerealium (or "grain thrips") is an insect of the phylum Arthropoda, known as parasite of plants of the family Gramineae; human infestation is not frequently described in literature. MATERIALS AND methods: We report the case of a 59-year-old female farmer, come to observation because of intense itching and sensation of "walking insects" on her head, with no objective cutaneous signs except lesions due to scratching. After repeated visits, in which negative results of clinical and laboratory tests suggested the diagnosis of "delusory syndrome" (Ekbom's syndrome), we finally isolated on her head some insects, identified by stereomicroscopy as L. cerealium. Careful inspection of the house of our patient allowed us to identify, as possible source of parasites, a wheat field and a deposit of grains used for animal feeding. Temporarily removing the patient from her usual environment resulted in complete clinical resolution. RESULTS: Peculiarity of symptoms caused by this parasite and consequent problems for a correct diagnosis are discussed, as well as possible solutions.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
5/13. Perniosis-like tinea corporis caused by trichophyton verrucosum in cold-exposed individuals.trichophyton verrucosum is a zoophilic infectious agent causing 98% of the dermatophytic infections of cattle. Transmission to humans has, until recently, been rare. One reason for an increase of infection in humans and animals seems to be the decrease in immunisation of cattle. We report on three cases of pertinent human infections with disseminated, sharply defined, bluish red, partly oedematous nodules and plaques in particular not only on the thighs, but also on the trunk and arms. Two of our patients work with farm animals. The third one works as an assistant in a butcher shop, but lives on a cow farm. All three patients are often exposed to the cold. In all three cases T. verrucosum was detected by culture. tinea corporis was histologically confirmed in two patients. Based on the microbiological results, we began a combined systemic and local antimycotic therapy with fluconazole 50 mg day(-1) in two patients, itraconazole 100 mg day(-1) in one patient p.o. combined with topical ciclopiroxolamine. All patients were cured. Dermatophytosis caused by T. verrucosum can, under certain circumstances, such as frequent exposure to cold or a long-term corticosteroid therapy, mimic the characteristic clinical picture of perniosis, as we demonstrate here.- - - - - - - - - - ranking = 2keywords = animal (Clic here for more details about this article) |
6/13. Farm animal feeders: another group affected by cereal flour asthma.asthma induced by cereal flour is a long recognized entity. We present studies of three patients affected by asthma related to exposure to cereal flour contained in animal formula feeds. skin prick test performed with the formula feed components showed positive reactions to cereal flours (wheat, rye and barley) and negative to the other substances in these formulas. Specific anti-wheat, rye and barley flour IgE antibodies were found by RAST. bronchial provocation tests (BPT) with wheat flour (patients 1 and 2) and barley flour (patient 3) all showed immediate responses. These findings suggest that our patients' symptoms were caused by an IgE-mediated hypersensitivity to cereal flours from animal formula feeds. We call attention to the importance of cereal flours in animal formula feeds as a cause of occupational asthma in farm and animal feeders.- - - - - - - - - - ranking = 8keywords = animal (Clic here for more details about this article) |
7/13. Occupational hearing impairment in pig breeders.Individuals employed at pig breeding facilities are exposed to potentially harmful noise from several sources. In a building housing about 1,100 pigs, the animals themselves were found to produce a sustained noise level between 95 and 104 dBA during the feeding procedure. High-pressure cleaners used for cleaning the buildings generate between 98 and 105 dBA. We present a case of typical noise-induced hearing loss, which, with reasonable certainty, can be ascribed entirely to this kind of noise exposure. General use of hearing protectors in the profession is recommended.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
8/13. microsporum nanum infection in hog farmers.microsporum nanum is a dermatophyte that can cause disease in both man and animals and is most frequently associated with ringworm infection in pigs. Human infections are rare in the literature. Three new cases of human M. nanum infection are reported here. Two patients had inflammatory tinea faciei and one had tinea cruris. The patients were successfully treated with clotrimazole or miconazole cream, sometimes combined with griseofulvin. All three patients were hog farmers and lived in the same small rural area. occupational exposure is suggested as the cause of infection.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
9/13. Abortion due to infection with chlamydia psittaci in a sheep farmer's wife.A farmer's wife who had helped with lambing aborted spontaneously in March after a short febrile illness in the 28th week of her pregnancy. She developed disseminated intravascular coagulation post partum with acute renal failure and pulmonary oedema. Recovery was complete after two weeks of hospital care. A strain of chlamydia psittaci, probably of ovine origin, was isolated from the placenta and fetus. The patient's serum showed rising titres of antibody against chlamydia group antigen; the placental and fetal isolates; and a known ovine abortion, but not a known avian, strain of C psittaci. IgG against both ovine abortion and enteric strains of C psittaci was detected, but IgM against only an abortion strain was detected. Histological examination showed pronounced intervillus placentitis with chlamydial inclusions in the trophoblast but no evidence of fetal infection or amnionitis. Laboratory evidence of chlamydial infection was found in an aborting ewe on the farm in January and in remaining sheep and lambs in July. Doctors should recognise the possible risk to pregnant women in rural areas where chlamydial infections in farm animals are widespread.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
10/13. October 1942: a strange epidemic paralysis in Saval, Verona, italy. Revision and diagnosis 50 years later of tri-ortho-cresyl phosphate poisoning.In the autumn of 1942 a strange epidemic paralysis started in Saval, at that time a country area but now part of the city of Verona. The epidemic went on for several months and affected 41 people, all working as owners or labourers on the same farm. Some of the farm animals (chickens, horses, cattle, pigs) also became ill. About 20 patients were admitted to the nearby city hospital. The outbreak was diagnosed as polyneuritis with a probable viral cause. Fifty years later, seven people with sequelae of the disease were examined. The most severe cases present a spastic paraplegia and lower leg muscle atrophy without sensory impairment, resembling an amyotrophic lateral sclerosis "frozen" for 50 years. The clinical syndrome can now be attributed confidently to organophosphate induced delayed polyneuropathy. All the epidemiological data obtained from the survivors were evaluated and a careful review of the literature was made. Contamination of the ground from a rubbish dump near the farmyard would explain the epidemiology of the Saval outbreak.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
