Assessment of malignant potential for HPV types 16, 52, and 58 in the uterine cervix within a Korean cohort.

High-risk human papillomavirus (HR-HPV) is the primary carcinogen in uterine cervical carcinoma. While genotype-specific carcinogenic risks have been extensively studied in Western populations, data from Korean are sparse. This study evaluates the malignant potential of the three most prevalent HR-HPVs in Korea: HPV16, HPV52, and HPV58.

Primary Solid Pseudopapillary Tumor of the Ovary: A Case Report and Review of the Literature.

Introduction: Solid pseudopapillary neoplasms (SPNs) are rare and mainly originate from the pancreas. SPNs originating from the ovary (SPN-O) are extremely rare, and only 13 cases have been reported in the English literature since 2010.

Case: We report a 31-year-old woman with SPN-O accompanied by multiple metastases in the abdominal cavity.

A Study on the Retrospective Reinterpretation of BRCA1 and BRCA2 Variants.

Background: Hereditary breast/ovarian cancer is associated with BRCA gene mutations. As large volumes of clinical data on BRCA variants are continuously updated, their clinical interpretation may change, leading to their reclassification. This study analyzed the class and proportion of the changed clinical interpretations of BRCA variants to validate the need for periodic reviews of these variants.

Recent Changes in the Human Metapneumovirus Outbreak at a University Hospital in Korea.

Background: Although the detection of respiratory viruses other than severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was significantly reduced because of quarantine due to the coronavirus disease (COVID-19) pandemic, an epidemic of several viruses was reported unexpectedly. We also detected a change in the pattern of human metapneumovirus (HMPV) outbreak compared to that before the COVID-19 pandemic. Therefore, the authors intended to identify the incidence and altered distribution pattern of the HMPV outbreak and provide useful information for clinical practice.

Changes in the Distribution of Respiratory Microorganisms before and during the COVID-19 Pandemic, Daegu, Korea.

Background: Acute respiratory infection (ARI) is the most common infectious disease in all ages and genders worldwide. Respiratory microorganisms such as respiratory viruses, are commonly responsible for causing ARI. COVID-19 is still prevalent in Korea.

Review of washing machine-related deaths in South Korea.

We reviewed data on washing machine-related deaths between 2008 and 2020 in South Korea to analyze the case characteristics, manners of death, and causes of death. Washing machine-related deaths are very rare, and only 23 incidents were identified over the study period. Of these cases, 19 (82.

Spindle cell oncocytoma of the sella turcica with anaplastic features and rapid progression in short-term follow-up: a case report with proposal of distinctive radiologic features.

We present a rare case of spindle cell oncocytoma (SCO) of the sella turcica with malignant histologic features and rapid progression. A 42-year-old woman experienced bilateral blurred vision and was preoperatively misdiagnosed as having a pituitary macroadenoma on magnetic resonance imaging. After surgery, SCO was diagnosed by the histopathologic features of interlacing fascicles of spindle tumor cells with finely granular, eosinophilic cytoplasm.

Successful laparoscopic surgery of accessory cavitated uterine mass in young women with severe dysmenorrhea.

Accessory cavitated uterine mass (ACUM) is a rare and unique condition seen in young women. We report cases of ACUMs in two patients, a 14-year-old girl and a 25-year-old woman, both with complaints of severe dysmenorrhea that had started at menarche and had progressively worsened since. A large cystic lesion was localized in the anterolateral wall of the myometrium separate from the endometrium, which was difficult to distinguish from congenital uterine anomalies.

Extramedullary tanycytic ependymoma of the lumbar spinal cord.

Tanycytic ependymoma is a rare variant of ependymoma that commonly affects the cervical and thoracic spinal cord. It usually arises as intramedullary lesions, and extramedullary cases are extremely rare. We report a case of a 44-year-old woman who was diagnosed with tanycytic ependymoma in her lumbar spine at level 2-3.

An autopsy case of fatal acute peritonitis complicated by illegal acupuncture therapy.

Acupuncture is an alternative medical therapy and widely practiced in Northeast Asia. Although it is known as a safe procedure, complications including infection, pneumothorax, hemorrhage, and cardiac tamponade have been reported. The authors present a rare case of fatal acute peritonitis due to penetration of acupuncture needles directly into the abdominal and pelvic cavity.

Plasma components affect accuracy of circulating cancer-related microRNA quantitation.

Circulating microRNAs (miRNAs) have emerged as candidate biomarkers of various diseases and conditions including malignancy and pregnancy. This approach requires sensitive and accurate quantitation of miRNA concentrations in body fluids. Herein we report that enzyme-based miRNA quantitation, which is currently the mainstream approach for identifying differences in miRNA abundance among samples, is skewed by endogenous serum factors that co-purify with miRNAs and anticoagulant agents used during collection.

Upregulated amniotic fluid cytokines and chemokines in emergency cerclage with protruding membranes.

PROBLEM  To identify the prognostic factors for pregnancy outcome in women who received emergency cerclage for dilated cervix with protruding membranes. METHOD OF STUDY  A prospective cohort study was performed, and a total of 14 women who received emergency cerclage were included. Clinical features and laboratory findings including amniotic fluid cytokines and chemokines were compared between women who had successful pregnancy (survival group, n = 6) and those who had perinatal death (non-survival group, n = 8).

Selective release of microRNA species from normal and malignant mammary epithelial cells.

MicroRNAs (miRNAs) in body fluids are candidate diagnostics for a variety of conditions and diseases, including breast cancer. One premise for using extracellular miRNAs to diagnose disease is the notion that the abundance of the miRNAs in body fluids reflects their abundance in the abnormal cells causing the disease. As a result, the search for such diagnostics in body fluids has focused on miRNAs that are abundant in the cells of origin.

Metastasizing dermatofibroma in lung.

Benign dermatofibroma is very common skin tumor and can very rarely metastasize. We report a case of metastasizing dermatofibroma on a 36-year-old woman who presented multiple bilateral lung nodules. She underwent incisional biopsy for cellular dermatofibroma of the right shoulder 7 years ago.

Expression and mutational analysis of c-kit in ovarian surface epithelial tumors.

Coexpression of Kit ligand and c-kit has been reported in some gynecologic tumors. To determine whether imatinib mesylate is useful in ovarian epithelial tumors, we performed immunohistochemical and mutational analysis. The cases consisted of 33 cases, which included 13 serous cystadenocarcinomas, 1 borderline serous tumor, 8 mucinous cystadenocarcinomas, 6 borderline mucinous tumors and 5 clear cell carcinomas.

The role of microsatellite instability at chromosome 11p15.5 in the progression of breast ductal carcinoma.

The study of microsatellite instability (MSI) has provided the evidence to support a sequential, progressive pathway for the development of cancer. In this study, we analyzed the role of MSI at chromosome 11p15.5 using microdissection of paraffin-embedded tissue from 68 matched normal and breast tumor samples.
