ABSTRACT
Students who are working in research or educational laboratories of parasitology, as well as health care workers providing care for patients, are at the risk of becoming infected with parasites through accidental exposure. The main purpose of this study was to identify potential positive cases of intestinal parasitic infections among students who took practical parasitology courses compared with students who did not take any practical parasitology courses in Lorestan University of Medical Sciences, Khorramabad, Iran, in 2013-2014. A total of 310 subjects from various majors were invited to voluntarily participate in the study. Various demographic data were collected using questionnaires. Three stool samples were collected from each individual on alternate days. Saline wet mounts [SWM], formalin-ether sedimentation test [FEST], Sheather floatation test [SHFT] and trichrome and modified Ziehl-Neelsen staining methods were used to diagnose the presence of intestinal parasites. The prevalence rate of intestinal parasites [IPs] among the students was 11.93%. There was a significant difference between majors in the infection with IPs [P < 0.05]. The most frequently observed IPs were Blastocystis hominis [4.51%] and Giardia intestinalis [3.54%]. The results of this study showed that the transmission of pathogenic parasites in the educational course of practical parasitology could occur and must be taken into careful consideration
ABSTRACT
Brucellosis is a zoonotic disease mostly transmitted to humans through consumption of unpasteurized dairy products and can lead to a systemic disease with any organ involvement. In this report, we describe a case of brucellosis-induced avascular necrosis of the hip. Brucellosis was diagnosed through serological tests, andavascular necrosis of the femoral head was confirmed by pelvic MRI. The patient was treated with a combination of antimicrobial treatments and referred to the orthopedic service for total hip arthroplasty. Brucellosis may present with unusual manifestations and should be always taken into consideration, particularly in endemic areas
