BackgroundSeveral reports have implied progressive increase of performance-enhancing drug (PED) use among Iranian athletes. More importantly, most of the previous research in the Iranian population had mainly focused on the anabolic steroid abuse, and ignored other agents.ObjectivesThe aim of this study was to investigate the prevalence and characteristics of PED use among bodybuilding athletes in Bushehr, south of Iran.MethodsFour hundred and fifty three male bodybuilding athletes were recruited from Bushehr gyms between February and May of 2015. Men were eligible to participate in the survey if they had regularly participated in the strength-training exercise (minimum of 1 year and 4 hour/week). Data were collected via a face-to-face interview. The survey consisted of three separate parts including demographic data, exercise pattern and PED use.ResultsAccording to this study, 234 (51.7%) of bodybuilding athletes had used PEDs. The PED users reported an average of 3.80 ± 4.52 agents’ use in their programs and they had used PEDs for the average of 3.24 ± 3.99 years. The most prevalent agents which had been abused by the athletes were anabolic steroids (used by 185 athletes (79.4% of athletes). Furthermore, 110 (47%) of athletes reported stimulant agents’ use during their routines. The most prevalent motivation for using PEDs was increasing muscle mass that was reported by 164 (70.1%) of PED users. In addition, sexual and dermatologic effects were the most prevalent adverse effects reported by the PED user athletes (114 (49.4%) and 103 (44.2%), respectively).ConclusionsThis study showed the high rate of PED use among recreational and professional Iranian bodybuilding athletes that can expose them to the serious side effects of these agents.

This work aimed to explore the concentration of nickel, manganese, iron, copper, chromium, and lead in the milk of goat herds in the industrial area of Asaluyeh (southern Iran) and the non-industrial area of Kaki. The milk of 16 goat herds (each herd had at least ten goats) was collected in several villages in each area, and at the same time, the drinking water and forage of goats were sampled. The concentration of elements in the samples was determined by ICP-OES. The mean concentrations of chromium, copper, iron, manganese, lead, and nickel in milk samples of the Asaluyeh area were 16.423 ± 0.349, 0.146 ± 0.118, 6.111 ± 0.501, 0.239 ± 0.016, 0.141 ± 0.030, and 1.447 ± 0.101 mg/kg, respectively. Concentrations of heavy metals (except for copper) in the milk of goats in the industrialized area of Asaluyeh were significantly higher than that of Kaki (P < 0.05). Also, the content of heavy metals was significantly correlated with lactose levels (P < 0.05). The hazard index for drinking the goat milk was computed to be 0.444 and 0.386 for the Asaluyeh and Kaki area, respectively, which shows a minimal effect of this exposure pathway.

The study demonstrated that Tc-MIBI scanning can be complementary to other diagnostic techniques in patients with cold thyroid nodules. In addition, because of its availability, rather low cost, simple protocol, and objective semiquantitative information, Tc-MIBI scanning seems to hold promise in routine imaging of cold thyroid nodules.

Merkel cell carcinoma is a rare tumor frequently involving the skin with an aggressive behavior and fatal outcome. It occurs mostly in the caucasian race between 60–80 years of age and it is rare in children. Herein we report our experience with a highly aggressive fatal Merkel cell carcinoma in an immunocompetent 17-year-old boy. Its characteristics and treatment modalities will be also discussed.

Papillary serous cystadenocarcinoma of the ovary is a common tumor but occurrence of ovarian type papillary serous cystadenocarcinoma in the testis is very rare. Herein we report such a case in a 49-year-old man presenting with testicular swelling. In this tumor, mesothelioma of tunica vaginalis should be excluded by immunohistochemistry. The best treatment is radial orchiectomy and it is very resistant to chemoradiation. Our case was well after orchiectomy and now after a year he is doing well and completely symptom free.
