The earliest report linking environmental （occupational） exposure to adverse human male reproductive effects dates back to1775 when an English physician, Percival Pott, reported a high incidence of scrotal cancer in chimney sweeps. This observation led to safety regulations in the form of bathing requirements for these workers. The fact that male-mediated reproductive harm in humans may be a result of toxicant exposures did not become firmly established until relatively recently, when Lancranjan studied lead-exposed workers in Romania in 1975, and later in 1977, when Whorton examined the effects of dibromochloropropane （DBCP） on male workers in California. Since these discoveries, several additional human reproductive toxicants have been identified through the convergence of laboratory and observational findings. Many research gaps remain, as the pool of potential human exposures with undetermined effects on male reproduction is vast. This review provides an overview of methods used to study the effects of exposures on male reproduction and their reproductive health, with a primary emphasis on the implementation and interpretation of human studies. Emphasis will be on occupational exposures, although much of the information is also useful in assessing environmental studies, occupational exposures are usually much higher and better defined.

AIM: To determine relationships between retinal nerve fiber layer(RNFL) thickness and nadir CD4 cell count in human immunodeficiency virus(HIV) positive patients evaluated for glaucoma ***: Data were reviewed for 329 HIV positive patients evaluated for glaucoma suspicion. High-definition optical coherence tomography(OCT) RNFL measurements were obtained at least 6 mo apart. Analyses were performed to identify relationships between nadir CD4 count and RNFL ***: Totally 110 eyes of 55 patients met inclusion criteria, of which 46 eyes were from subjects with nadir CD4<200 cells/mm^3 and 64 had nadir CD4≥200 cells/mm^3. Patients with nadir CD4<200 cells/mm^3 had significantly thicker superior(119.7±18.6 μm) and temporal(63.8±11.7 μm) quadrants at time of initial OCT compared to the superior(112.8±16.8 μm, P=0.048) and temporal(57.1±11.9 μm, P=0.004) quadrants of patients with higher nadir CD4. This trend toward thicker RNFL among subjects with lower nadir CD4 cell counts persisted at the time of follow up OCT where participants with nadir CD4<200 cells/mm^3 showed average RNFL thickness in the superior and temporal quadrants of 117.9±18.3 μm and 63.8±12.8 μm, respectively, compared to a superior thickness of 110.5±16.9 μm(P=0.034) and temporal thickness of 57.3±11.6 μm(P=0.007) among those with higher nadir CD4. CONCLUSION: Patients with lower nadir CD4 cell counts have thicker RNFL in the superior and temporal quadrants compared to those with higher nadir CD4 counts. RNFL thickness in HIV positive patients may be affected by historic HIV disease control and should be considered when evaluating HIV positive patients for glaucoma.

Inflammatory bowel diseases (IBD) such as Crohn's disease (CD) or ulcerative colitis are chronic intestina disorders, which are on the increase in "Westernised" countries. IBD can be caused by both genetic and environmental factors. Interleukin-10 (IL-10) is an immunoregulatory cytokine that has been identified as being involved in several diseases including IBD. Studies have shown that polymorphisms in the promoter region reduce serum levels of IL-10 and this reduction has been associated with some forms of IBD. Mouse models have shown promising results with IL-10 supplementation, as such IL-10 supplementation has been touted as being a possible alternative treatment for CD in humans. Clinical trials have shown that recombinant human IL-10 is safe and well tolerated up to a dose o 8 μg/kg. However, to date, the results of the clinica trials have been disappointing. Although CD activity was reduced as measured by the CD activity index IL-10 supplementation did not result in significantly reduced remission rates or clinical improvements when compared to placebo. This review discusses why IL-10supplementation is not effective in CD patients currently and what can be addressed to potentially make IL-10 supplementation a more viable treatment option in the future. Based on the current research we conclude that IL-10 supplementation is not a one size fits all treatment and if the correct population of patients is chosen then IL-10 supplementation could be of benefit.
