The medulloblastoma is a tumor of the cerebellum, particulary common in children. Most of them in childhood are situated in the midline vermis, but in adults are in the lateral lobes. The authors reported two cases of medulloblastoma which developed in the midline vermis although the patients were adult, and reviewed with concerned articles.

BACKGROUND: Heart Rate Variability help us to diagnose the impairment of autonomic nervous system in patients with diabetes, hypertension, ischemic heart disease, chronic renal disease, and arrhythmia. Change of autonomic nervous system is related to circadian rhythm, stress, physical activity, and so on. Especially, impairment of vagal nervous system with age help us to expect sudden cardiac death, myocardial infarction, and arrhythmia. So we survey heart rate variability by using 24 hours holter monitoring to expect impairment of autonomic nervous system in elderly hypertensive patients. METHODS: In order to assess 24 hours heart rate variability, we use Del Mar Avionics 563 holter monitoring on 11 elderly hypertensive patients( > or =65 years), 12 younger hypertensive patients( <65 years), and 15 normal subjects. RESULTS: 1) Standard deviation of mean R-R interval, LF(low frequency), HF(high frequency), TPSD(total power spectral density) are more decreased in elderly hypertensive patients than in younger hypertensive patients in 24 hours health rate variability analysis(t-test p<0.05). 2) According to age, elderly control group had lower LF power spectral parameter than younger control group had, but other parameters were not decreased, and elderly hypertensive group had lower LF, HF, TPSD, SD of mean R-R interval than younger hypertensive group did(p<0.05). 3) In circardian rhythm, normal subjects had high HF power spectral parameter and low LF power spectral parameter at evening and night. On the other hand, elderly hypertensive group had constant low level of LF, HF power spectral parameter during the day and night. CONCLUSIONS: On heart rate variability analysis using by 24 hours Holter monitoring, heart rate variability was decreased, and impairment of autonomic nervous system was accelerated in elderly hypertensive patients.

OBJECTIVE: Pattern with essential hypertension generally shows the same circadian pattern as the normothensive person with a night-time reduction or "DIP" in blood pressure in sleep. The definition of "Dipper" and "Non-dipper" are assigned according to arbitrary criteria e.g. a night time average blood pressure which is at least 10% less than the average daytime blood pressure. Prospective evidence that the absence of an overnight dip is a strong adverse prognostic indicator for target organ damage .Thus we investigate circardian rhythm of blood pressure, related target organ damage, its frequency & drug in hypertensive subjects. Method : 24hr ambulatory blood pressure monitoring, history taking, physical examination, fundoscopy, ECG, chest X ray, dipstick urinanlysis, serum creatinine level are performed in essential hypertensive subjects. Exclusion criteria are duration of hypertension over 5 years, DM, renovascular hypertension & heart failure. RESULTS: Total 42 patients performed study.17 subjects classify dipper group,25 subjects classify non-dipper group. Between dipper & non-dipper group shows no significantly difference at stroke history, C/T ratio over 0.5 in chest X-ray, left ventrcular hypertrophy in ECG,ST-T change in ECG, proteinuria & serum creatinine level. Non-dipper group shows significantly difference to dipper group in frequency of hypertensive retinopathy and number of combined drug used subjects. CONCLUSION: Number of hypertensive retinopathy is significantly frequency in non-dipper group. Hypertensive retinopathy is atherosclerotic complication, thus we predict other target organ damage, therefore non-dipper type circardian rhythm of blood pressure is adverse prognostic factor for target organ damage of hypertensive subjects.

Most cases of hypertriglyceridemia (HTG)-induced gestational pancreatitis occur when a person with hyperlipidemia is overweight due to pregnancy or has secondary triggers associated with triglycerides (TGs). In Korea, 6 cases of HTG-induced gestational pancreatitis have been reported, but none of the affected patients had TG levels below 1,000 mg/dL. A 36-year-old female at 30 weeks of gestation was admitted due to pain in her upper abdomen. Initial biochemical analysis revealed a TG level of 260 mg/dL, an amylase level of 2,951 U/L and a lipase level of 3,500 U/L. Abdominal ultrasonography showed pancreatic swelling with a hypoechogenic rim. After several days, the patient was discharged and had a normal delivery at 38 weeks of gestation. This case report is the first to describe acute pancreatitis occurring in the presence of type IV hyperlipoproteinemia even though the TG level was less than 500 mg/dL, contrary to findings in previously reported cases.

BACKGROUND AND OBJECTIVES:
Recently, Genoss drug-eluting stent (DES)â„¢ stent comprising cobalt-chromium platform with an ultrathin strut thickness, sirolimus, and an abluminal biodegradable polymer was developed. Owing to the lack of substantial evidence for the safety and efficacy of this stent, we report 12-month results of the Genoss DESâ„¢ stent.
METHODS:
We analyzed subjects who were eligible for a 12-month follow-up from the ongoing Genoss DESâ„¢ registry, which is a prospective, single-arm, observational, multicenter trial to investigate the clinical outcomes after the successful Genoss DESâ„¢ stent implantation among all-comers. The primary endpoint was a device-oriented composite outcome, defined as cardiac death, target vessel-related myocardial infarction, and target lesion revascularization at 12-month follow-up.
RESULTS:
Among 622 subjects, the mean age of subjects was 66.5±10.4 years, 70.6% were males, 67.5% had hypertension, and 38.3% had diabetes. The implanted stent number, diameter, and length per patient were 1.5±0.8, 3.1±0.4 mm, and 36.0±23.3 mm, respectively. At 12-month clinical follow-up, the primary endpoint occurred only in 4 (0.6%) subjects.
CONCLUSIONS
The novel Genoss DESâ„¢ stent exhibited excellent safety and efficacy in real-world practice.

Background/Aims:
The Genoss DES™ is a novel, biodegradable, polymer-coated, sirolimus-eluting stent with a cobalt- chromium stent platform and thin strut. Although the safety and effectiveness of this stent have been previously investigated, real-world clinical outcomes data are lacking. Therefore, the aim of this prospective, multicenter trial was to evaluate the clinical safety and effectiveness of the Genoss DES™ in all-comer patients undergoing percutaneous coronary intervention.
Methods:
The Genoss DES registry is a prospective, single-arm, observational trial for evaluation of clinical outcomes after Genoss DES™ implantation in all-comer patients undergoing percutaneous coronary intervention from 17 sites in South Korea. The primary endpoint was a device-oriented composite outcome of cardiac death, target vessel-related myocardial infarction (MI), and clinically driven target lesion revascularization (TLR) at 12 months.
Results:
A total of 1,999 patients (66.4 ± 11.1 years of age; 72.8% male) were analyzed. At baseline, 62.8% and 36.7% of patients had hypertension and diabetes, respectively. The implanted stent number, diameter, and length per patient were 1.5 ± 0.8, 3.1 ± 0.5 mm, and 37.0 ± 25.0 mm, respectively. The primary endpoint occurred in 1.8% patients, with a cardiac death rate of 1.1%, target vessel-related MI rate of 0.2%, and clinically driven TLR rate of 0.8%.
Conclusions
In this real-world registry, the Genoss DES™ demonstrated excellent safety and effectiveness at 12 months among all-comer patients undergoing percutaneous coronary intervention. These findings suggest that the Genoss DES™ may be a viable treatment option for patients with coronary artery disease.
