Skin Hydration Measurement: Comparison Between Devices and Clinical Evaluations.

Background: The need for an objective method for measuring skin hydration levels is becoming increasingly important. Various devices with different measuring principles for assessing skin hydration have been developed and are widely used.

Objective: This study aimed to investigate the reproducibility and correlation between clinical evaluation and skin hydration measurement devices that are the most widely used in the field.

Cartilage-hair hypoplasia-anauxetic dysplasia spectrum disorders harboring RMRP mutations in two Korean children: A case report.

Rationale: Cartilage-hair hypoplasia (CHH, OMIM # 250250) is a rare autosomal recessive disorder, which includes cartilage-hair hypoplasia-anauxetic dysplasia (CHH-AD) spectrum disorders. CHH-AD is caused by homozygous or compound heterozygous mutations in the RNA component of the mitochondrial RNA-processing Endoribonuclease (RMRP) gene.

Patient Concerns: Here, we report 2 cases of Korean children with CHH-AD.

Prognostic analysis according to European LeukemiaNet 2022 risk stratification for elderly patients with acute myeloid leukemia treated with decitabine.

Objectives: This study aimed to evaluate the prognostic significance of the revised European LeukemiaNet (ELN)-2022 risk stratification model for 123 elderly acute myeloid leukemia (AML) patients treated with decitabine chemotherapy.

Results: Based on the ELN-2022 risk stratification, 15 (12.2%), 51 (41.

Reference intervals of cell population data parameters in Sysmex XN-Series and its patterns of changes from early adulthood to geriatric ages in South Korea.

Introduction: Cell population data (CPD) parameters may be putative biomarkers for the screening of various diseases including some infections and myelodysplastic syndrome. This study aimed to establish the age- and sex-specific reference intervals (RIs) for the CPD parameters in the Korean population.

Methods: The reference population for the RIs of CPD parameters comprised 124 856 subjects aged 20-99 years.

The prognostic impact of reduced variant burden in elderly patients with acute myeloid leukemia treated with decitabine.

Background/aims: We evaluated the role of next-generation sequencing (NGS)-based disease monitoring for elderly patients diagnosed with acute myeloid leukemia (AML) who received decitabine therapy.

Methods: A total of 123 patients aged > 65 years with AML who received decitabine were eligible. We analyzed the dynamics of variant allele frequency (VAF) in 49 available follow-up samples after the fourth cycle of decitabine.

Overexpression of Prohibitin 2 Protein is Associated with Adverse Prognosis in Cytogenetically Normal Acute Myeloid Leukemia.

Cytogenetically normal acute myeloid leukemia (CN-AML) accounts for 40%-50% of all AML cases. Despite advances in understanding the molecular pathophysiology of CN-AML, its clinical outcome remains unsatisfactory and unpredictable. To investigate its clinical implication in CN-AML, we measured the expression of prohibitin 2 (PHB2) using immunohistochemical staining (IHCS) of paraffin-embedded bone marrow sections from 134 CN-AML patients.

Evaluation of a Fully Automated Antinuclear Antibody Indirect Immunofluorescence Assay in Routine Use.

Indirect immunofluorescence assay (IFA) using HEp-2 cells as a substrate is the gold standard for detecting antinuclear antibodies (ANA) in patient serum. However, the ANA IFA has labor-intensive nature of the procedure and lacks adequate standardization. To overcome these drawbacks, the automation has been developed and implemented to the clinical laboratory.

Association between secondhand smoke exposure and hypertension in never smokers: a cross-sectional survey using data from Korean National Health and Nutritional Examination Survey V, 2010-2012.

Objectives: Secondhand smoke (SHS) exposure is associated with cardiovascular disease. This study aims to determine the association between SHS exposure estimated by questionnaire and hypertension in Korean never smokers.

Setting: Korean National Health and Nutrition Examination Survey (KNHANES) V was conducted from 2010 to 2012.

Evaluation of matrix-assisted laser desorption/ionization time-of-fight mass spectrometry for identification of 345 clinical isolates of Aspergillus species from 11 Korean hospitals: comparison with molecular identification.

We evaluated the ability of the Filamentous Fungi Library 1.0 of the MALDI-TOF MS Biotyper system to identify 345 clinical Aspergillus isolates from 11 Korean hospitals. Compared with results of the internal transcribed spacer region sequencing, the frequencies of correct identification at the species-complex level were 94.
