Colonic Polyp Study: Differences in Adenoma Characteristics Based on Colonoscopy History over 5-Year Follow-Up Period.

: Timely detection and removal of colonic adenomas are critical for preventing colorectal cancer. : This study analyzed differences in colonic adenoma characteristics based on colonoscopy history by reviewing the medical records of 14,029 patients who underwent colonoscopy between January and June 2020 across 40 primary medical institutions in Korea. : Adenoma and advanced neoplasia characteristics varied significantly with colonoscopy history ( < 0.

Evaluation of the dosimetric and radiobiological parameters in four radiotherapy regimens for synchronous bilateral breast cancer.

This study is to investigate the optimal treatment option for synchronous bilateral breast cancer (SBBC) by comparing dosimetric and radiobiological parameters of intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) plans using single and dual isocenters. Twenty patients with SBBC without lymph node involvement were selected retrospectively. Four treatment plans were generated for each patient using the Eclipse treatment planning system (Varian Medical System, Palo Alto, CA, USA) following two delivery techniques with two isocenter conditions-IMRT using a single isocenter (IMRT_Iso1), VMAT using a single isocenter (VMAT_Iso1), IMRT using dual isocenters (IMRT_Iso2), and VMAT using dual isocenters (VMAT_Iso2).

Colon Polyp Detection in Primary Health Care Institutions of Korea: Detection Rate and Issues with Following the Guidelines.

Background/aims: There have been few multicenter studies on colonic polyps conducted by primary medical institutions. This study examined the detection rate of colonic polyps in primary health care institutions and the related factors while following the guidelines.

Methods: The medical records of 14,029 patients who underwent colonoscopy between January-June 2020 at 40 primary medical institutions in Korea were analyzed.

Extensive Disease Subtypes in Adult Patients with Ulcerative Colitis: Non-pancolitis Versus Pancolitis.

Background And Aim: Few studies have compared pancolitis and non-pancolitis E3 in adult patients with ulcerative colitis (UC). This study aimed to evaluate the natural disease courses and factors affecting outcomes between pancolitis and non-pancolitis E3.

Methods: We retrospectively analyzed 117 patients, including 93 with extensive colitis (E3) and 24 with UC confined to the rectum or left-sided colon and appendiceal orifice inflammation at the time of diagnosis, who were regularly followed up for at least 1 year.

Aspergillus Tracheobronchitis and Influenza A Co-infection in a Patient with AIDS and Neutropenia.

Aspergillus tracheobronchitis (AT), an unusual form of invasive pulmonary aspergillosis (IPA), is characterized by pseudomembrane formation, ulcer or obstruction that is predominantly confined to tracheobronchial tree. Hematologic malignancies, neutropenia, solid organ transplantation, chronic corticosteroid therapy and acquired immunodeficiency syndrome (AIDS) are known to be major predisposing conditions. However, since the introduction of highly active antiretroviral therapy, there is only one reported case of AT in AIDS patient.

Primary tumor maximum standardized uptake value measured on 18F-fluorodeoxyglucose positron emission tomography-computed tomography is a prognostic value for survival in bile duct and gallbladder cancer.

Background/aims: Few studies have assessed the prognostic value of the primary tumor maximum standardized uptake value (SUV max) measured by 2-[(18)F]-fluoro-2-deoxy-D-glucose PET-CT for patients with bile duct and gallbladder cancer.

Methods: A retrospective analysis of 61 patients with confirmed bile duct and gallbladder cancer who underwent FDG PET-CT in Kangbuk Samsung Medical Center (Seoul, Korea) from April 2008 to April 2011. Prognostic significance of SUV max and other clinicopathological variables was assessed.

The influence of waist circumference on insulin resistance and nonalcoholic fatty liver disease in apparently healthy Korean adults.

Background/aims: Waist circumference (WC) is a risk factor for metabolic syndrome and is related to insulin resistance (IR) and nonalcoholic fatty liver disease (NAFLD). The purpose of this study was to determine the association between WC and IR and NAFLD in apparently healthy Korean adults.

Methods: The volunteers included in this cross-sectional study comprised 9,159 adults (5,052 men, 4,107 women) who participated in a comprehensive health checkup program.
