In leprosy patients, both IFN-gamma and TNF-alpha are immunoprotective, whereas IL-2R, IL-10, and IL-1beta are immunosuppressive. Our results indicate that type I reaction, with increased levels of IFN-gamma, is a cell-mediated immune response, whereas type II reaction, with increased levels of IL-10, is essentially an immune complex disease.

Cryopreservation of human spermatozoa offers a pre-therapeutic possibility of preserving progenity in patients with testicular tumours. We aimed to investigate effects of cryopreservation and addition of catalase on sperm motility, vitality and DNA integrity in fresh and swim-up spermatozoa. Semen samples were collected from 50 fertile men. Each sample was divided into two parts. First part was subdivided into two equal aliquots: both cryopreserved with and without catalase. The second part was subdivided into two equal aliquots: both processed by swim up and then cryopreserved with or without catalase. Semen analyses, sperm vitality and sperm DNA integrity were performed. Sperm concentration showed significant decrease while percentage of progressive motility, sperm vitality and % of DNA damage showed significant increase in processed and cryopreserved processed samples when compared with fresh and cryopreserved fresh samples. There was no significant difference in sperm concentration while there was significant increase in % of progressive motility and sperm vitality and % of DNA damage showed significant decrease in samples with catalase when compared with samples without catalase (either fresh or processed). Catalase supplementation (fresh and processed) during cryopreservation results in better post-thawing percentage of progressive motility and percentage of sperm vitality and improved DNA integrity.

MDT caused a reduction in serum cytokines correlated with a reduction in the bacterial burden. It is advisable to continue MDT for PB patients for 1 year. Serum IL-1beta levels may have a prognostic value for the susceptibility of leprosy patients to the development of reactions.

Trichloroacetic acid peeling is effective in the treatment of melasma, TCA 25% was the most effective concentration. Q-switched neodymium-doped:yttrium aluminum garnet laser is not recommended in the treatment of melasma because it was associated with the highest incidence of complications.
