This chapter discusses the synthesis and analysis of near-infrared fluorescent activity-based probes for imaging cysteine protease activity, reporting potential benefits for disease diagnosis but noting challenges in imaging specific locations with high cathepsin activity.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

In this study, researchers found that girls aged 4-8 years with isolated premature thelarche had significantly advanced bone age, with obesity and elevated serum IGF-1 SDS and DHEAS SDS being key independent risk factors.

This case report highlights a 33-year-old male initially misdiagnosed with Neuromyelitis Optica, whose symptoms may improve with biotin treatment due to late onset biotinidase deficiency.

This study developed a novel method to analyze the effects of COL7A1 mutations using mRNA from peripheral blood mononuclear cells, aiding genetic diagnosis and potential therapies for dystrophic epidermolysis bullosa.

This report describes two patients with ichthyosis linearis circumflexa exhibiting symptoms resembling Netherton's disease, noting multiple hair shaft defects and discussing a possible connection to aminoaciduria.

This case report describes a girl with Denys-Drash syndrome misdiagnosed with hyperandrogenism due to biotin interference in immunoassays, highlighting the need for awareness of laboratory result discrepancies.

In this study, BPA rapidly increased dendritic spine and synapse densities in cultured rat hippocampal neurons, with involvement of estrogen receptors and ERK1/2 and p38 pathways, but disrupted dihydrotestosterone's effects on synaptic plasticity.

This study found that dermatology patients with tattoos or piercings may have a higher risk of body dysmorphic disorder tendencies and lower acceptance of their illness.

This study confirms the presence of large structural variations in the genome of Nellore cattle, which may contribute to their environmental adaptation to tropical regions.

This case study reports a 36-year-old man with KID syndrome caused by an N14Y GJB2 mutation, expanding the mutation spectrum of this condition in the Chinese population.

Basonuclin helps identify and track hair follicle development and cycling in mice.

This review discusses three newly identified forms of epidermolysis bullosa related to mutations in DST-e, EXPH5, and ITGA3, offering insights into their genetic and clinical characteristics but reports no new clinical results.

This study found that biotin supplementation is common among patients at a dermatology clinic despite a lack of evidence for its dermatologic benefits and potential interference with lab tests.

Dr. Connelly agrees that linear basal cell carcinomas might be more aggressive but highlights the study's lack of clear criteria to identify them.

RCS-01 is safe and may help rejuvenate aging skin.

This case study describes a 54-year-old man with an E600A mutation in the NOD-2 gene associated with Blau syndrome, who presented with skin involvement, differing from typical cases, and initially responded to colchicine treatment.

This study identifies two previously unreported pathogenic RIPK4 gene variants, suggesting a functional link with cell adhesion molecules in ectodermal dysplasias.

This study reports that a 9-week-old infant with Netherton syndrome showed rapid and sustained symptom improvement, including skin microbiome normalization and developmental progress, after off-label dupilumab treatment, without adverse reactions.

This case report describes an 11-month-old infant with Biotinidase deficiency who exhibited multifocal seizures, neuroregression, alopecia, and skin issues, highlighting prompt diagnosis and the dramatic clinical response to biotin treatment.

This study reports that the monoclonal antibody BKN-1 specifically stained basal cell epithelioma cells and certain normal skin structures, indicating a similarity in keratin expression between the tumor and follicular epithelium below the isthmus portion.

In this study, researchers in Southeastern Wisconsin characterized circulating SARS-CoV-2 lineages, notably identifying the dominance of Omicron variants, including sublineages XBB.1.5, XBB.1.16, and XBB.1.9.1, which exhibit mutations aiding viral transmission and immune evasion. This genetic analysis supports public health efforts in monitoring evolving virus strains.

In this study, researchers found that BST2 expression is significantly upregulated in skin sections of mice with alopecia areata, implicating BST2's role in the disease pathogenesis through the action of epidermal γδ T cells and macrophages.

In this study, researchers identified a recurrent nonsense mutation, c.409C>T (p.Arg137*), in the COL7A1 gene through whole exome sequencing in a family with autosomal recessive dystrophic epidermolysis bullosa, demonstrating the importance of this method for diagnosing genetically complex conditions.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This study utilized the USFDA AERS to identify significant associations between various medications—such as anti-osteoporotic drugs and phenytoin—and gingival disorders, noting emergent signals with finasteride, COVID-19 vaccine, and levothyroxine, suggesting a need for awareness of oral side effects.

This case report describes the diagnosis of Netherton's syndrome in two young sisters, attributing their serious erythrodermia, poor hair growth, and atopic conditions to this hereditary condition.

This study suggests that nestin is an important marker for identifying HMB-45-negative cells in nodular melanomas, particularly in the dermal parts.

This case report highlights a 12-year-old boy with twenty nail dystrophy in isolation, emphasizing the need for thorough physical exams to distinguish nail disorders and provide appropriate management and counseling on the condition's benign nature and good prognosis.
