PURPOSE: Exercise is frequently recommended in the management of diabetes mellitus(DM) and can improve blood control by increasing insulin sensitivity and psychological benefits. Exercise can result in good glycemic control in type 2 DM, when combined with diet and drug therapy. However, in type 1 DM, the expected improvement in glycemic control with exercise have not been clearly established. Effects of exercise on glycemic control in patients with type 1 DM were investigated. METHODS: 20 patients with of type 1 DM, who were no retinopathy, neuropathy, nephropathy and cardiac disorders, were enrolled and exercised for 30min. with 50% of individualized maximum VO2. Blood sugar concentration were measured before, immediate and 15min after exercise. The results were evaluated with HbA1c, C-peptide and DM duration. RESULTS: Blood sugar concentration were significantly decreased from pre-exercise 198+/-9.7mg/dL to immediate 145+/-7.1mg/dL and at 15min. Post-exercise 134+/-4.0mg/dL(P<0.05). In case with HbA1c<10%, there was significantly decreased in blood sugar level from pre-exercise 176+/-9.7mg/dL to immediate 123+/-63.2mg/dL and at 15min post-exercise 113+/-1.9mg/dL(P<0.05). In case with HbA1c>10% there was also significantly decreased in blood sugar levels 222+/-64.7mg/dL, 169+/-6.1mg/dL, 157+/-1.2mg/dL respectively(P<0.05). Group with moderate decreased blood sugar(40-99mg/dL) was 8 patients(42.1%), group with mild decreased blood sugar(<40mg/dL) was 7 patients(36.8%) and group with decreased more than 100mg/dL was 4 patients(21.5%). There was no correlation in degree of decreased blood sugar concentration among HbA1c, C-peptide, DM duration. CONCLUSION: Proper exercise in type 1 diabetic children can decrease blood sugar level significantly and make good glycemic control and can decrease DM microvascular complications in addition to motivating physically active lifestyle.

OBJECTIVES: The myelodysplastic syndromes (MDS) are a group of acquired clonal hematopoietic disorders characterized by peripheral cytopenias and a hypercellular or normocellular dysplastic bone marrow. The mechanisms responsible for development of MDS are not known. We performed this study to evaluate the hematopoietic abnormalities and apoptosis in MDS. METHODS: Long-term bone marrow culture (LTBMC) was performed for colony assays, cobblestone area assay, stromal morphologic changes from 7 patients with MDS and 7 normal controls. In situ nick end labeling (ISNEL) method was performed for detection of apoptosis from LTBMC in 7 patients with MDS and 7 normal controls. ISNEL method also performed in bone marrow cell bloc samples in 36 patients with MI3S. RESULTS: Viability of nonadherent cells from LTBMC of patients with MDS was not decreased compared with normal controls at 1 week, but significantly decreased at 2 and 3 weeks compared with normal controls (P<0.0001). Formation of the cobblestone areas from patients with MDS was slightly decreased compared with normal controls at 1st week, but significantly decreased at 2nd and 3rd weeks compared with normal controls (P<0.0001). Slightly decreased compared with normal controls at 1 week, but significantly decreased at 2 and 3 weeks compared with normal controls (P<0.0001). Stromal layers produced in LTBMC of normal controls and 1 patient with MDS were detected at 1 week and were formed confluent stroma from 3 weeks, but another patients with MDS who did not form a confluent stroma. Patients with MDS had significantly lower colony forming unit granulocyte-macrophage (CFU-GM) compared with normal controls at 1 (P<0.01) and 2 weeks (P<0.001) of LTBMC. Two weeks of LTBMC resulted more profound inhibition of CFU-GM formation than 1 week (P<0.0001). Apoptotic cell death was absent in adherent and non adherent cells from normal controls at 1 and 2 weeks, but massive apoptotic cell death was found in adherent and non adherent cells from patients with MDS at 1 and 2 weeks and the degree of apoptosis was profound at 2 weeks compared with 1 week. Among the 36 patients, fifteen patients demonstrated varying degrees of apoptosis positive cells, 4 having low, 8 intermediates, and 3 high scores. Remaining 21 patients showed absent apoptosis or only occasional positive cells. CONCLUSION: Hematopoietic abnormalities such as a failure of differentiation are caused by the stromal defects and the biologic basis of the apparent paradox of peripheral cytopenias in the face of hypercellular (or normocellular) marrow is related by intramedullary apoptotic cell death of the stromal and hematopoietic cells.

Glycogen storage diseases(GSD) are inherited disorders affecting glycogen metabolism and type I GSD is due to the absence or deficiency of glucose-6-phosphatase(G6Pase) enzyme in the liver, kidney, and intestinal mucosa. The defect leads to inadequate hepatic conversion of G6P to glucose and thus make affected individuals susceptible to fasting hypoglycemia, and the accumulation of glycogen occurs in the liver and other organs. Type Ia is the most common form of GSD and clinically growth retardation may manifest of GSD itself rather than growth hormone deficiency(GHD), but we experienced a case of type I GSD with GHD in a 14-year-o1d male. The height was 125 cm, compatible with 50 th percentile of height of 8 years of age. He has doll-like face with fat cheek, relatively thin extremities, and metabolic acidosis, hyperuricemia, hypoglycemia, hyperlipidemia. GH stimulation test with clonidine and L-dopa revealed that the patient had decreased GH secretion. After laboratory work up including liver biopsy, he was diagnosed as type I GSD. Hypoglycemia was managed with frequent feeding with high starch diet(uncooked cornstarch). Metabolic acidosis and hyperuricemia were treated with sodium bicarbonate, allopurinol and probenecid. The patient is being followed at out-patient clinic with clinical improvement after of diet therapy and GH administration.

Purpose:
High-risk pregnancy, resulting in major complications, such as abortion, gestational hypertension, and preterm labor, are on the rise, requiring intervention. Increased concentration of particulate matter that is 10 μg per cubic meter or less in diameter (PM10) due to increased air pollution and industrialization has recently been noted as a risk factor for health problems, and prior studies have reported that PM10 is related to abortion, gestational hypertension, and preterm labor.
Methods:
This study used data from the Korean medical panel between 2008 and 2016 to identify 879 women with normal pregnancies and 301 women diagnosed with high-risk pregnancies. The association between high-risk pregnancy and PM10 was analyzed using the annual average regional concentration during the same period by the Korea Environment Corporation.
Results:
At 35 years of age or older, the risk of abortion (p<0.001; 95% confidence interval [CI], 1.43–2.71) and preterm labor increased (p<0.05; 95% CI, 0.33–0.90). Married pregnant women were at a high risk of preterm labor (p<0.05; 95% CI, 0.25–0.98), and the prevalence of gestational hypertension was high in the metropolitan area (p<0.05; 95% CI, 12.09–25.93). On comparing the average annual concentration of particulate matter according to the level of atmospheric ventilation of the Korea Environment Corporation using a cutoff of ≤50 μg/m3, the probability of preterm labor was 2.2 times higher in groups exposed to particulate matter concentration of ≥50 μg/m3 (p<0.01; 95% CI, 1.49–3.25).
Conclusion
PM10 was related to preterm labor, and the risk of preterm labor was high if the average annual concentration of PM10 in the individual’s residential area exceeded 50 μg/m3.

Background:
Dipeptidyl peptidase-4 inhibitor (DPP-4i) and renin-angiotensin system (RAS) blockade are reported to affect the clinical course of coronavirus disease 2019 (COVID-19) in patients with diabetes mellitus (DM).
Methods:
As of May 2020, analysis was conducted on all subjects who could confirm their history of claims related to COVID-19 in the National Health Insurance Review and Assessment Service (HIRA) database in Korea. Using this dataset, we compared the short-term prognosis of COVID-19 infection according to the use of DPP-4i and RAS blockade. Additionally, we validated the results using the National Health Insurance Service (NHIS) of Korea dataset.
Results:
Totally, data of 67,850 subjects were accessible in the HIRA dataset. Of these, 5,080 were confirmed COVID-19. Among these, 832 subjects with DM were selected for analysis in this study. Among the subjects, 263 (31.6%) and 327 (39.3%) were DPP4i and RAS blockade users, respectively. Thirty-four subjects (4.09%) received intensive care or died. The adjusted odds ratio for severe treatment among DPP-4i users was 0.362 (95% confidence interval [CI], 0.135 to 0.971), and that for RAS blockade users was 0.599 (95% CI, 0.251 to 1.431). These findings were consistent with the analysis based on the NHIS data using 704 final subjects. The adjusted odds ratio for severe treatment among DPP-4i users was 0.303 (95% CI, 0.135 to 0.682), and that for RAS blockade users was 0.811 (95% CI, 0.391 to 1.682).
Conclusion
This study suggests that DPP-4i is significantly associated with a better clinical outcome of patients with COVID-19.

A 19-year-old boy was admitted with complaints of headache and generalized seizure for 5 months. On physical examination, he had a moon-face, a farty breast, no sexual hair, and childish voice. Neurological examination showed no abnormality except slightly decreased visual acuity in the left eye. Lumbar CSF had total 194 leucocytes in a high power field, and among these 95% was lymphocyte. Marked sellar ballooning was seen in simple X-rays. Both carotid angiogram revealed bilateral A1 elevation as tent-like fashion, and subfrontal mass was suspected in lateral view. Transfrontal Conray ventriculography was done, and accidentally tumor cyst was punctured and dark pinkish blood was evacuated. Transcoronal ventriculography was again performed and we knew the cystic subfrontal midline mass. Tumor mass was nearly removed, and pathological report was germinoma. He was discharged and radiation theraphy was given. He is well for 7 months post-operatively.
