An 87-year-old male with old myocardial infarction was referred to the hospital due to left femur neck fracture and intermittent dizziness. Significant 2:1 atrioventricular block was demonstrated on initial electrocardiogram (Figure 1). Transthoracic echocardiography showed reduced left ventricular function (LVEF = 47%) with regional wall motion abnormality of right coronary artery (RCA) and left circumflex coronary artery (LCx) artery. Coronary angiography showed patent previous proximal RCA and distal LCx stents. Temporary pacemaker was inserted initially and the patient was planned for permanent pacemaker insertion after the surgery.

We report a patient with severe ataxia due to Dandy-Walker malformation, who showed functional recovery over 10 months corresponding to a change in a cerebellar peduncle lesion. A 20-month-old female patient who was diagnosed with Dandy-Walker syndrome and six age- and sex-matched healthy control subjects were enrolled. The superior cerebellar peduncle, the middle cerebellar peduncle, and the inferior cerebellar peduncle were evaluated using fractional anisotropy and the apparent diffusion coefficient. The patients＇ functional ambulation category was 0 at the initial visit, but improved to 2 at the follow-up evaluation, and Berg＇s balance scale score also improved from 0 to 7. Initial diffusion tensor tractography revealed that the inferior cerebellar peduncle was not detected, that the fractional anisotropy of the superior cerebellar peduncle and middle cerebellar peduncle decreased by two standard deviations below, and that the apparent diffusion coefficient increased by two standard deviations over normal control values. However, on follow-up diffusion tensor tractography, both inferior cerebellar peduncles could be detected, and the fractional anisotropy of superior cerebellar peduncle increased to within two standard deviations of normal controls. The functional improvement in this patient appeared to correspond to changes in these cerebellar peduncles. We believe that evaluating cerebellar peduncles using diffusion tensor imaging is useful in cases when a cerebellar peduncle lesion is suspected.

Dear Editor,Myeloid differentiation was shown to be associated with reduced leukemic cell burden and leukemia-initiating cells and improved survival[1].Reactive oxygen species(ROS)are associated with leukemia and can induce endoplasmic reticulum(ER)*** stress induces several mechanisms,including cell death[2].The stimulator of interferon genes(STING)is also an ER transmembrane protein and promotes anti-tumor immunity by linking innate and adaptive immunity[3].Signal transducer and activator of transcription 6(STAT6)plays a prominent role in adaptive immunity by transducing signals fromextracellular cytokines and inducing apoptosis in cancer cells[4].

AIM: To investigate prevalence and risk factors for colorectal neoplasms in adults aged < 50 years, for whom screening is not ***: This cross-sectional study compared prevalence and characteristics of colorectal and advanced adenomas in patients aged < 50 years who underwent colonoscopy screening with subjects aged ≥ 50 years. To evaluate risk factors for colorectal and advanced adenoma in young adults, we used multivariable logistic regression models. Colorectal neoplasm characteristics were evaluated and compared with those in older ***: Among 2819 patients included, prevalences of colorectal adenoma and advanced adenoma were 19.7% and 1.5%, respectively. As patient age increased, so did the prevalence of colorectal neoplasm. However, prevalence of advanced adenoma did not differ between age-groups 45-49 years and ≥ 50 years(OR = 0.43, 95%CI: 0.17-1.07, P = 0.070). In younger age-group(< 50 years), colorectal adenoma was significantly associated with older age, waist circumference(OR = 1.72, 95%CI: 1.15-2.55, P = 0.008), and current smoking(OR = 1.60, 95%CI: 1.07-2.41, P = 0.023). Alcohol consumption was an independent risk factor for colorectal advanced adenoma(OR = 3.69, 95%CI: 1.08-12.54, P = 0.037). Multiple neoplasms and large neoplasms(≥ 1 cm) were more prevalent in subjects ≥ 50 ***: Current screening strategies for colorectal cancer may need to be amended to account for patient age, especially in young subjects with abdominal obesity, current smoking and alcohol consumption.
