To determine immunologic reactivity to Bacillus anthrax antigens, we conducted serologic testing of workers in a factory that performed scouring of wool and goat hair. Of 66 workers, approximately 10% had circulating antibodies or T lymphocytes that reacted with anthrax protective antigen. Individual immunity varied from undetectable to high.
Malignant rectal melanoma is a rare tumour. We report a case of a 66-year-old man who presented with a two-month history of rectal bleeding, pain, and tenesmus. A semicircular rectal tumour was seen, just above the dentate line. Biopsies proved it to be an amelanotic malignant melanoma, as protein S100, melanoma antigen HMB45 and Melan-A expression were… (More)
In a Belgian wool-processing factory, living anthrax spores were found in raw goat hair and air dust, but confirmed anthrax cases had never been reported. Anthrax vaccines are not licensed nor recommended in Belgium. We conducted a B. anthracis seroprevalence study to investigate risk factors associated with positive serology and advise on protective… (More)
OBJECTIVE To evaluate if FNAC (Fine Needle Aspiration Cytology) is a useful tool in the detection of malignancy in thyroid surgery. FNAC is used routinely as a preoperative diagnostic technique and surgical strategy is often adapted. But is FNAC such a good technique in defining surgical strategy? METHODS We retrospectively reviewed all files of 703… (More)
Pelvic actinomycosis is a rare complication of a long-term intrauterine contraceptive device. Early diagnosis is important, as clinical and radiological imaging may mimic a malignant pathology and lead to radical and unnecessary surgery. We report a case of pelvic actinomycosis in a woman who had used an intrauterine contraceptive device for the last 13… (More)
