Palmoplantar keratoderma is a complex skin condition with diverse clinical presentations and genetic factors, making diagnosis challenging and sparking the need for comprehensive genetic testing.
This study collected data from 142 patients over several years to understand the different types and genetic causes of palmoplantar keratoderma by examining clinical features and performing genetic sequencing.
Results revealed that a significant proportion (83%) of families had identifiable genetic variants, with the most common variant linked to the AAGAB gene, affecting the majority of participants who presented with a punctate subtype of the condition.
α-Antitrypsin deficiency leads to higher elastase activity and elastin breakdown, potentially contributing to cancer risks.
A study involving over 29,000 individuals in Denmark shows that those with this deficiency have significantly higher rates of skin cancer, leukemia, and liver cancer compared to those without the deficiency.
The risk for skin cancer was particularly elevated in individuals with other health issues like chronic obstructive pulmonary disease (COPD) and skin diseases, indicating a compounded risk for certain populations.
Ectodermal dysplasias are rare genetic disorders characterized by features like missing teeth (hypodontia), hair loss (hypotrichosis), and impaired sweating (hypohidrosis), with limited research on their prevalence in the general population.
This study aimed to create a reliable population-based cohort of ectodermal dysplasia patients in Denmark, assessing prevalence and their characteristics using comprehensive health registry data from 1995 to 2021.
The research identified 396 patients, establishing a minimum birth prevalence of 14.5 cases per 100,000 live births and confirming that a majority of diagnosed cases were correctly coded in health registries.
The global burden of hidradenitis suppurativa (HS) is poorly understood due to limited and varying prevalence data, which has been affected by different methodologies and diagnostic approaches.
The Global Hidradenitis Suppurativa Atlas (GHiSA) aims to accurately determine HS prevalence by using a validated questionnaire for screening, followed by physician validation for positive cases, assessing about 10% of negatives for diagnostic accuracy.
Currently, GHiSA is conducting prevalence studies in 58 countries to create a comprehensive global prevalence estimate through proportional meta-analysis, allowing for direct international comparisons that were not previously feasible.
