Isolated tuberculosis of testis: A case report.

BACKGROUND: Extrapulmonary tuberculosis accounts for only 15% of new cases of tuberculosis. In extrapulmonary tuberculosis, usually affected areas include bone, pleura, lymph nodes, genitourinary system, joints, peritoneum and meninges. Tuberculosis epididymo-orchitis is an uncommon type of extrapulmonary tuberculosis. CASE PRESENTATION: We reported a case of tuberculosis epididymo-orchitis and involvement of the left testicle in a 37-year-old male patient. The left testicle had a heterogeneous parenchymal echo, and multiple hypo-echo and ill-defined areas were evident in the left testicle. In the color Doppler ultrasound, the left testicle with the epididymis on both sides was completely hyperemic. The findings were primarily in the favor of extrapulmonary tuberculosis. Therefore, after a 2-month first-stage treatment with four-drug therapy of anti-TB drugs such as rifampin 150 mg, isoniazid 75 mg, pyrazinamide 400 mg and ethambutol 275 mg, considering the weight of the patient (56 kg), 4 pills per day and the second phase with two-drug therapy, rifampin 150 mg and 75 mg of isoniazid, 4 pills per day for 4 months, extrapulmonary tuberculosis symptoms improved to a large extent. CONCLUSION: To prevent epididymectomy and the effects that the disease may have on fertility, it should be tried to quickly diagnose and treat the disease at the same early stage of the disease.

Occupational Exposure and Health Impairments of Formaldehyde on Employees of a Wood Industry.

BACKGROUND: Occupational exposure to formaldehyde may decrease white blood cell counts and change blood concentration. In this study, the influences of occupational exposure to formaldehyde on the number of white blood cells and blood concentrations were studied. METHODS: This case-control study was conducted in June of 2012 at North Wood Factory, Golestan Province, Iran. The US-NIOSH method No. 2541 was used to determine the occupational exposure of 30 workers of the production line (case group) and 30 administrative staffs (control group) to formalde-hyde. The number of white blood cells and blood concentration were determined using the normal blood count method and related indices. Demographic features as well as the symptoms of being exposed to formaldehyde were collected using a standard questionnaire. RESULTS: The occupational exposure of case group ranged from 0.50 ppm to 1.52 ppm. The prevalence of all studied symptoms from formaldehyde exposure in workers (2
