This case report concluded that undiagnosed Menkes disease, an X-linked disorder causing copper deficiency, contributed to a 7-month-old's illness and death, complicating his presentation with viral septic shock and methamphetamine exposure.

This case report describes a 35-year-old man who developed an atypical DRESS syndrome after taking topiramate for migraine prevention, which resolved with drug withdrawal and symptomatic treatment.

Drug addicts often have scars, skin color changes, blocked veins, and bruising, with severe ulcers from barbiturate injections.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study observed that dietary intake of glucoraphanin during juvenile and adolescent stages prevented cognitive deficits and abnormal gene expressions in the brain of adult offspring exposed to maternal immune activation, potentially implicating centrosome-related genes in the development of psychosis.

This study found that a single application of 'Lye' or 'No-Lye' chemical straighteners significantly reduced drug concentrations in hair samples from both drug-fortified standards and authentic drug users.

This letter reports three cases of diffuse hair loss linked to hyperprolactinaemia but does not present new research findings.

This study observed that while PrEP was effective among transgender women if taken, adherence was low, especially among those at higher risk.

This review discusses the growing use of scalp hair for elemental analysis in various fields and highlights advancements in analysis techniques, including the future potential of laser ablation ICP-MS, but reports no new clinical results.

This review proposes focusing on relationships between neuroactive steroids and psychiatric disorder symptoms, rather than relying on traditional disorder classifications, and reports no new clinical findings.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This article reviews hair analysis for drug detection and its applications in various fields, but reports no new research findings, emphasizing the need to consider the method's complexities and potential pitfalls.

This study developed and validated a high-resolution mass spectrometry method to screen for prohibited substances and analyze six endogenous steroids in urine according to World Antidoping Agency requirements, demonstrating its effectiveness for antidoping analysis.

This article reviews the unique health issues and preventive care recommendations for LGBT individuals, emphasizing dermatologic considerations and the importance of culturally competent care, but reports no new clinical findings.

This review discusses the historical and current use of ribosome-inactivating protein-expressing plants in traditional medicine across various cultures and regions, highlighting their role despite a lack of scientific validation.

This study introduces MicrobeFDT, a tool that clusters chemically similar compounds and links them to gut microbial enzymes and toxicities, demonstrating its utility by uncovering previously unknown metabolism of the cancer drug altretamine.

In this study, several compounds, including estrogen and Dutasteride, showed neuroprotective effects on dopaminergic neurons in an MPTP mouse model of Parkinson's disease.

In this study, finasteride altered acute ethanol withdrawal severity differently in male and female mice, highlighting sex differences in sensitivity to changes in neurosteroid levels.

This review discusses micro-segmental hair analysis for forensic toxicology, emphasizing its potential to provide detailed drug distribution profiles and its application in investigations, while noting the method's limitations and future perspectives.

This study found that acute sleep deprivation enhanced 5α-reductase expression and activity in the rat prefrontal cortex, and finasteride treatment reduced associated psychosis- and mania-like behaviors.

This review discusses common psychodermatologic conditions and provides practical diagnostic and therapeutic recommendations but reports no new results; the authors emphasize the challenge of treating patients who lack insight into their psychiatric symptoms.

This study found that minoxidil prevents long-term serotonergic toxicity induced by MDMA in rats, primarily by opening mitochondrial KATP channels and involving Akt and MAP kinases in its neuroprotective mechanism.

This article overviews dermatologic findings in forensic pathology and reports no new results; it emphasizes the importance of recognizing skin manifestations in identifying types of injury.

This study concluded that standard decontamination procedures do not fully remove external contamination from post mortem hair specimens, which complicates using hair analysis to assess long-term drug exposure.

This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.
