This study investigated the sub-acute toxicity of Eclipta alba extract in Wistar albino rats, finding generally comparable hematological and biochemical parameters to controls, but noted mild morphological liver and kidney changes at the highest dose, highlighting a key area for further safety research.

This study identified that high concentrations of selenium in a liquid dietary supplement caused a widespread outbreak of poisoning, revealing the importance of stricter manufacturing standards.

This study found that EGFR and MEK inhibitors may induce acneiform skin toxicities by interacting with the skin bacterium Cutibacterium acnes to increase IL-36γ and IL-8 production in keratinocytes.

This study found that royal jelly may have a cardioprotective effect against paclitaxel-induced damage in rats by reducing oxidative and nitrosative stress, lowering cardiac biomarker levels, and mitigating heart tissue injuries.

This article reviews drug-induced hair and nail disorders and discusses their clinical recognition, underlying mechanisms, and potential treatment strategies, without presenting new research findings.

This study found that oral pumpkin seed oil increased hair follicle proliferation in mice without causing liver toxicity, unlike finasteride and minoxidil which showed adverse effects.

In this study on Sprague-Dawley rats, 0.60 mg/kg doses of L-Se-methylselenocysteine and sodium selenite were associated with liver toxicity and reduced sperm motility, while Se-enriched peptides showed no observable adverse effects up to 0.60 mg/kg.

This study found that dexpanthenol treatment reduced inflammation, oxidative stress, and apoptosis in rats, providing a protective effect against lipopolysaccharide-induced cardiac and endothelial damage.

This report describes a case where selenium supplementation in excess may have led to toxic liver injury, suggesting that high-dose selenium can cause hepatic necrosis.

This study found that essential oils from A. sinensis and L. sinense 'chuanxiong' were safe and significantly promoted hair regrowth in mice with dehydrotestosterone-induced androgenetic alopecia, outperforming 3% minoxidil in follicle number and dermal thickness improvements, suggesting potential use in hair loss treatments.

This study found that linoleic acid may help protect against acrylamide toxicity in female albino rats.

This report presents a rare case where a patient with chronic urticaria developed alopecia areata during azathioprine therapy, accompanied by bone marrow suppression; these effects resolved after stopping the medication, suggesting a possible link between azathioprine and autoimmune activation despite its intended immunosuppressive use.

In this study, copper-doxorubicin liposomes with multidose therapy reduced systemic toxicity compared to ammonium sulfate-loaded doxorubicin liposomes, while combinatorial strategies further enhanced tumor regression and accumulation.

This study reports two cases of erlotinib-induced erosive pustular dermatosis of the scalp in patients with non-small cell lung cancer, emphasizing the need for dermatological monitoring during EGFR inhibitor therapy.

This review discusses the potential impact of COVID-19 on the male reproductive system and highlights unanswered questions regarding its mechanisms and implications for men's health and fertility, reporting no new clinical results.

This study found that the YH0618 decoction reduced chemotherapy-induced nail discoloration, alopecia, skin hyperpigmentation, and fatigue in cancer patients who completed chemotherapy.

This article discusses the symptoms, diagnosis, and treatment of thallium poisoning, with no new clinical results reported; the authors emphasize the importance of early suspicion for effective intervention.

In this study, QR 678 and QR 678 Neo formulations containing growth factors and peptides were found to be safe in vitro and promoted hair growth in vivo in an animal model, suggesting their potential as treatments for alopecia, including secondary alopecia post-chemotherapy.

Low-intensity ultrasound may help protect hair follicles from chemotherapy-induced hair loss.

This study found that in patients with genetic generalized epilepsies, certain gene variants were linked to differences in valproic acid treatment outcomes, including a higher likelihood of treatment failure, varying serum drug concentrations, and specific side effects like weight gain and hair loss.

This study investigates differences in nutritional status, vitamin, and mineral levels between individuals with telogen effluvium and a control group, aiming to understand the nutritional factors involved in this condition.

In this study, lecithin/n-propanol/isopropyl myristate/water/tetracaine hydrochloride microemulsion was found to be a safe carrier for transdermal drug delivery in animal models, with analgesic effects on Wistar rats.

In this study, researchers developed a hair tonic using shallots (Allium cepa L.) and found that its F2 formulation was as effective as the positive control in promoting hair growth on the 21st day and remained stable over 28 weeks of testing.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

In this descriptive study, researchers assessed the most common short-term side effects of anthracycline and taxane-based chemotherapy in 122 Moroccan women with localized breast cancer, documenting frequent systemic, gastrointestinal, dermatological, neurological, musculoskeletal, and ocular toxicities.

This study found that high doses of finasteride were associated with reduced total cholesterol and body weight gain in LDLR-deficient mice.

This review discusses treatments for demodicosis in adults and children and provides no new clinical results; the authors emphasize the need for careful diagnosis and therapy selection.

This review establishes a tolerable upper intake level of 255 μg/day for selenium in adults, warning that supplements and Brazil nuts may cause excess intake.

This case report describes a patient with painful skin lesions during sorafenib treatment whose symptoms improved after receiving photodynamic therapy, suggesting it might help manage similar refractory skin toxicity cases.

This review discusses the 2023 International Guideline for PCOS assessment and management, highlighting updated evidence-based recommendations and practice points aimed at improving care and health outcomes, but notes that research quality remains generally low to moderate.
