This case report documents a reversible instance of complete body hair loss (alopecia universalis) in a patient undergoing chronic hepatitis C treatment with pegylated interferon alpha-2b and ribavirin, with hair regrowth observed within three months after therapy completion.

Testosterone replacement therapy can prevent men from fathering children and should not be used by those wanting to stay fertile.

In this study, researchers found that hepatitis C virus infection is a significant risk factor for sporadic porphyria cutanea tarda, suggesting familial cases might be more prevalent in areas with low hepatitis C infection rates.

In this study, a high daily dose of interferon alfa-2b administered initially six times a week for two weeks followed by thrice weekly for 12 weeks was most effective in sustaining normal ALT values in patients.

This study reported that while lichen planus was not significantly linked to hepatitis C virus infection, pruritus, dry skin, and hair loss were more common in HCV patients post-interferon treatment.

This study of Danish women found no evidence linking hair cortisol concentration to hair dyeing status or the frequency of hair washing.

This study found that radiofrequency treatment, with or without hydrolyzed collagen, increased dermis thickness, neocollagenesis, and FGF2 overexpression in rat skin tissue.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This article reviews the association between hepatitis C virus and systemic disorders like mixed cryoglobulinemia, highlighting potential autoimmune side effects from interferon-a2b treatments, and reports no new clinical results.

This study concluded that wedge resection in patients with polycystic ovary syndrome did not significantly affect androgen status or the biochemical features of the condition, though most regained regular menstrual cycles and some became pregnant.

This case study highlights that even short-term use of hydroxychloroquine for COVID-19 can potentially lead to acute generalized exanthematous pustulosis as an adverse effect.

This study found that alcohol dependence is associated with altered HPA axis functioning, with AD patients showing higher hair cortisol concentrations and reduced ACTH and cortisol levels, irrespective of childhood maltreatment history.

This study found that variations in Kv1 channel gene expression in the electric organ of Sternopygus correlate with sex differences and individual variations in their electric communication signals.

This study found that cortisol concentrations were significantly higher in hair samples with follicles compared to those without, suggesting potential confounding in stress assessments using different hair sampling methods.

This study found that women with polycystic ovary syndrome have elevated cardiovascular risk markers, with levels being higher in obese participants compared to non-obese participants.

This review discusses zinc supplementation as a complementary therapy for chronic hepatitis C, noting its potential benefits in improving treatment outcomes and reducing side effects, but reports no new clinical results.

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

This study found that hair cortisol concentration is a promising stress indicator in cattle but not in pigs, where external factors and lower cortisol response may interfere with its validity.

This study found that treatment with vitamin D increased the expression of LL-37 through the vitamin D receptor in cultured sebocytes.

This case study reports that hormonal imbalances in a young boy with precocious pseudopuberty returned to normal after the removal of a testicular interstitial cell tumor, with normal spontaneous puberty following.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

This study found no significant difference in hair cortisol concentrations, a chronic stress indicator, between sows in farrowing crates and those in loose-housing systems.

This study found that adjuvant sorafenib after hepatic resection improved overall survival in patients with intermediate and advanced hepatocellular carcinoma, compared to surgery only.

This study observed that certain herbal extracts may promote hair growth and inhibit hair loss in cell lines by affecting specific protein expressions similarly to minoxidil.

In this study, researchers found that the pCLCA2 protein is expressed in specific areas of pig skin, but its role in skin structure or function remains unclear.

This study found that hCG decreased 5α-reductase and androgen receptor levels in skin samples from women in vitro, suggesting that human skin responds to LH/hCG treatment.

This study observed that combined treatment with thyroxine and hydrocortisone increased lipid accretion and fat cell development in hypophysectomized fetal pigs, suggesting a key role of these hormones in fetal adipogenesis.

In this study, combining deferasirox with sorafenib significantly reduced liver fibrosis and preneoplastic lesions in rats while also lessening adverse effects compared to sorafenib alone.

This case report describes a 49-year-old woman with Sweet syndrome who experienced complete resolution of skin lesions after a prednisone treatment regimen.

This study reported that relocation in police horses was associated with elevated hair cortisol concentrations, possibly suggesting altered welfare due to changed surroundings, and that seasonal variations affected both cortisol levels and hair growth.
