To assess the detection rate of nutcracker syndrome in children with isolated hematuria, renal Doppler ultrasound examinations were routinely performed on 216 consecutive children (176 microscopic hematuria and 40 gross hematuria). Renal Doppler ultrasound was also performed on 32 healthy normal children. The peak velocity (PV) was measured at the hilar portion of the left renal vein (LRV) and at the LRV between the aorta and the superior mesenteric artery. The PV at the aortomesenteric portion

BACKGROUND AND AIM: In this study, we analyzed the clinical and pathological features of biliary intraductal papillary neoplasms (IPN-B) according to the location of the tumors. METHODS: A total of 55 patients with IPN-B were analyzed. We divided them into three groups: common bile duct (CBD), hilar, and intrahepatic duct (IHD) groups. The clinical and laboratory findings, cell types, depth of invasion, malignancy, existence of stones, lymph node metastasis, recurrence, and survival rate were an

Postoperative pulmonary complications (PPCs) are one of the most important causes of postoperative morbidity and mortality after abdominal surgery. Although chronic obstructive pulmonary disease (COPD) has been considered a risk factor for PPCs, it remains unclear whether mild-to-moderate COPD is a risk factor. This retrospective cohort study included 387 subjects who underwent abdominal surgery with general anesthesia in a tertiary referral hospital. PPCs included pneumonia, pulmonary edema, pu

Background: AMP-activated protein kinase (AMPK) not only functions as an intracellular energy sensor and regulator, but is also a general sensor of oxidative stress. Furthermore, there is recent evidence that it participates in limiting acute inflammatory reactions, apoptosis and cellular senescence. Thus, it may oppose the development of chronic obstructive pulmonary disease. Methods: To investigate the role of AMPK in cigarette smoke-induced lung inflammation and emphysema we first compared ci

Response evaluations that use the mRECIST provide more accurate prognoses than those that use the RECIST 1.1 in HCC patients treated with TARE.

Treatment of HCC is often based on the clinical judgment of clinicians because of the heterogeneity among individuals. Experts need to continue discussions on the standardization and sub-classification of HCC treatment guidelines in Korea.

Conventionally, it has been argued that the aponeurosis meets the orbital septum below the upper tarsal border in Orientals. However, we have shown that the aponeurosis fused with the orbital septum above the upper tarsal border in 502 patients, which contradicts the classic concept. In 457 patients there were distinct layers of fascia anterior to the orbital septum that originate from the septum and insert onto the pretarsal aponeurotic expansion. In Oriental eyelids, the preaponeurotic fat and

Non-alcoholic fatty liver disease (NAFLD) is associated with an increased hepatocellular carcinoma (HCC) risk. We established and validated a liver stiffness (LS)-based risk prediction model for HCC development in patients with NAFLD. A total of 2666 and 467 patients with NAFLD were recruited in the training and validation cohorts, respectively. NAFLD was defined as controlled attenuated parameter ≥238 dB/m by transient elastography. Over a median of 64.6 months, HCC developed in 22 (0.8%) subje
