Background: The clinical utility of urinary red blood cell (RBC) distribution (URD) remains limited. This study aimed to compare the diagnostic performance of URD and dysmorphic RBC (dRBC) in a multicenter study.
Methods: This study enrolled 703 patients who visited four tertiary medical centers in Korea.
Mutations in the gene are associated with autosomal recessive spastic ataxia of Charlevoix-Saguenay disease (ARSACS) or complex clinical phenotypes of Charcot-Marie-Tooth disease (CMT). This study aimed to identify mutations in a Korean CMT cohort with cerebellar ataxia and spasticity by whole exome sequencing (WES). As a result, eight pathogenic mutations in four families were identified as the underlying causes of these complex phenotypes.

It is primarily associated with mutations in the gene, which encodes a key enzyme of sialic acid biosynthesis (UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase). This study was performed to find mutations in six independent distal myopathy patients with or without peripheral neuropathy using whole-exome sequencing (WES).

HER2 protein expression and gene amplification status were analyzed using immunohistochemistry (IHC) and silver in situ hybridization (SISH), respectively.

A nonsense mutation deleting the C-terminal SOCS box in the gene was identified in a family with axonal peripheral neuropathy (Charcot-Marie-Tooth disease type 2), and pathogenicity of the mutation was assessed in model organisms of zebrafish and . Compared to control fish, zebrafish larvae transformed by the human mutant showed a defective swimming pattern of stalling with restricted localization and slower motility.

Objective: To identify the risk factors for failure of first-line poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance therapy in patients with advanced ovarian cancer.
Method: Patients with stage III-IV epithelial ovarian cancer who received first-line PARPi maintenance therapy were retrospectively reviewed. Clinicopathologic factors were compared between two groups-recur/progression of disease (PD) and non-recur/PD.
Objectives: To evaluate oncologic and pregnancy outcomes of fertility-sparing treatment (FST) using progestin in patients with stage I grade 2 endometrioid endometrial cancer (EC) without myometrial invasion (MI) or grade 1-2 with superficial MI.
Methods: Multicenter data of patients with stage I grade 2 EC without MI or grade 1-2 EC with superficial MI, who received FST between 2005 and 2021, were analyzed. Cox regression analysis identified independent factors for progressive disease (PD) during the FST.

In the Laparoscopic Approach to Cervical Cancer trial, minimally invasive surgery (MIS) has been associated with significantly lower disease-free survival and overall survival rates. The proposed reasons for the increased recurrence and mortality associated with MIS are uterine manipulation, the effect of insufflation gas (CO), and intracorporeal colpotomy. We applied 2 techniques during surgery to reduce tumor spillage in laparoscopic radical hysterectomy (LRH), which included avoiding using a uterine manipulator and containing the colpotomy using an endoscopic stapler.

Reference images for typical urinary crystals are common, however, but images for interpreting atypical urinary crystals are very rare. The authors reviewed various forms and solubility tests of urine crystals to interpret atypical crystals found in clinical specimens.

This study was performed to identify PMP22 mutations and to analyze the genotype−phenotype correlation in Korean CMT families. By the application of whole-exome sequencing (WES) and targeted gene panel sequencing (TS), we identified 14 pathogenic or likely pathogenic PMP22 mutations in 21 families out of 850 CMT families who were negative for 17p12 (PMP22) duplication.

Methods: We retrospectively reviewed the data of patients with presumed stage IA, grade 1 endometrioid endometrial cancer who developed intra-uterine recurrence after a complete response with fertility-sparing treatment using progestin. Oncological and pregnancy outcomes were analyzed after repeated fertility-sparing treatment.
Objective: To compare the effects of minimally invasive surgery (MIS) and open surgery (OPS) on the risk of recurrence and mortality in patients with endometrial cancer (EC) of high-risk histology (grade 3 endometrioid adenocarcinoma, papillary serous carcinoma [PS], clear cell carcinoma [CC], and carcinosarcoma) using meta-analysis.
Material And Methods: We systematically reviewed published studies comparing MIS and OPS in EC patients with high-risk histology until January 2022. The endpoints were recurrence and mortality rate.
This study aimed to determine whether endocervical glandular involvement (GI) affects the clinical prognosis of patients with cervical intraepithelial neoplasia (CIN) III who underwent the loop electrosurgical excision procedure (LEEP). This retrospective study included 250 patients who underwent LEEP for the treatment of CIN III between August 2005 and May 2020. The medical records of 234 patients were analyzed; 137 (58.

Objective: This study was performed to find CMT1C patients with mutation of LITAF in a Korean CMT cohort and to characterize their clinical features.
Small heat shock proteins (sHSPs) are ATP-independent chaperones that help correct the folding of denatured proteins and protect cells from stress. Mutations in , , and are implicated in inherited peripheral neuropathies (IPNs), such as Charcot-Marie-Tooth disease type 2 (CMT2) and distal hereditary motor neuropathies (dHMN). This study, using whole exome sequencing or targeted gene sequencing, identified 9 pathogenic or likely pathogenic variants in these three sHSP genes from 11 Korean IPN families.

Charcot-Marie-Tooth disease (CMT) is the most common hereditary peripheral neuropathy. Mutations in the neurofilament light polypeptide (NEFL) gene produce diverse clinical phenotypes, including demyelinating (CMT1F), axonal (CMT2E), and intermediate (CMTDIG) neuropathies. From 2005 to 2020, 1,143 Korean CMT families underwent gene sequencing, and we investigated the clinical, genetic, and neuroimaging spectra of NEFL-related CMT patients.
