Background: This study aimed to investigate the recent prevalence, management, and comorbidities of diabetes among Korean adults aged ≥30 years by analyzing nationally representative data. Methods: This study used data from the Korea National Health and Nutrition Examination Survey from 2016 to 2018, and the percentage and total number of people ≥30 years of age with diabetes and impaired fasting glucose (IFG) were estimated. Results: In 2018, 13.8% of Korean adults aged ≥30 years had diabetes, and adults aged ≥65 years showed a prevalence rate of 28%. The prevalence of IFG was 26.9% in adults aged ≥30 years. From 2016 to 2018, 35% of the subjects with diabetes were not aware of their condition. Regarding comorbidities, 53.2% and 61.3% were obese and hypertensive, respectively, and 72% had hypercholesterolemia as defined by low-density lipoprotein cholesterol (LDL-C) ≥100 mg/dL in people with diabetes. Of the subjects with diabetes, 43.7% had both hypertension and hypercholesterolemia. With regard to glycemic control, only 28.3% reached the target level of <6.5%. Moreover, only 11.5% of subjects with diabetes met all three targets of glycosylated hemoglobin, blood pressure, and LDL-C. The percentage of energy intake from carbohydrates was higher in diabetes patients than in those without diabetes, while that from protein and fat was lower in subjects with diabetes. Conclusion The high prevalence and low control rate of diabetes and its comorbidities in Korean adults were confirmed. More stringent efforts are needed to improve the comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.

Purpose: To report a case of a successful secondary Descemet membrane endothelial keratoplasty in failed penetrating keratoplasty. Case summary: A 46-year-old male with keratoconus in both of his eyes underwent penetrating keratoplasty in his right eye 30 years ago and in his left eye 14 years ago. From one and a half year ago, the patient’s visual acuity decreased in his left eye due to graft failure. For treatment, secondary Descemet membrane endothelial keratoplasty was performed. Partial detachment of Descemet membrane was observed at 13 days after the operation, and an additional air injection was performed. At 8 months after the operation, the patient’s uncorrected visual acuity improved to 0.5 and the cornea maintained its clearance without rejection. Conclusions Secondary Descemet membrane endothelial keratoplasty was successfully performed in a patient with failed penetrating keratoplasty.

BACKGROUND: Diabetic patients are known to have unusually high mean intraocular pressure (IOP); attributable to autonomic dysfunction and genetic factors. A recent study reported that diabetic complications occur in not only diabetes but also prediabetes. We performed this study to analyze the relationship between glycated hemoglobin A1c (HbA1c) levels and IOP in non-diabetics using electronic medical records at the health screening center of Soon Chun Hyang University Seoul Hospital.METHODS: We considered 16,643 individuals who visited the health screening center of Soon Chun Hyang University Seoul Hospital between November 2015 and September 2017. In total, 3,029 subjects were included in the study. Exclusion criteria included a history of hypertension, diabetes, stroke, cardiovascular disease, hepatitis (A-C), cancer, other disease, fasting blood glucose of 126 mg/dL or higher, HbA1c of 6.5% or higher, and individuals whose binocular IOP could not be measured. We categorized subjects into two groups; those with HbA1c less than or equal to 5.6%, and those with HbA1c greater than 5.6% and less than 6.5%. The mean IOP of each group was compared by gender.RESULTS: After adjusting for factors affecting IOP, analysis of variance was performed to analyze the relationship between HbA1c and IOP. There was no statistically significant difference between the HbA1c groups in males. However, there was a significant difference in IOP between females in the the higher and lower HbA1c groups.CONCLUSION: There was a statistically significant relationship between mean IOP and HbA1c in females without diabetes. Further research is needed with prospective and extensive data collection.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD) is common in asthma patients. Proton pump inhibitor (PPI) therapy improves symptoms of asthma in some patients. The objective of this study was to investigate endoscopic findings of GERD in asthma patients and to assess the effect of gastric acid suppression with the PPIs on symptom improvement and pulmonary function. METHODS: From 105 consecutive patients with GERD symptoms during follow up for asthma, 45 patients were enrolled. Patients enrolled to this study were asked about GERD symptoms before and after treating with PPI. Endoscopic findings were described according to Los Angeles classification. The improvement of asthma symptoms and follow-up pulmonary function test were investigated after administration of PPIs. RESULTS: Esophageal symptoms such as heartburn and acid reflux were present in 25 patients (55.6%), and patients without esophageal symptoms were 20 (44.4%). The degree of endoscopic abnormality was not significantly different between groups with or without esophageal symptoms. The improvement of symptoms was seen in 44 patients (97.8%) except 1 patient after administration of PPIs. The number of patients classified to the low-dose group was 7 patients (15.6%) and that of patients classified to the standard-dose group was 38 patients (84.4%). The follow-up pulmonary function test, peak expiratory flow rate (L/sec) was improved in 3 patients (3 of 7, 42.9%) of the low-dose group, and in 24 patients (24 of 38, 63.2%) of the standard-dose group. The improvement of ventilatory function was not significantly different according to dose of PPIs. CONCLUSIONS: Treatment with PPIs is expected to improve subjective symptoms and ventilatory function in asthma patients.

Nontuberculous mycobacterial infections are a rare, but clinically important cause of infections in continuous ambulatory peritoneal dialysis (CAPD) patients. This is typically suspected when a patient does not respond to treatment with the usual antibiotics. We describe here a case of Mycobacterium abscessus exit site infection with abdominal wall abscess formation that was associated with CAPD, which required peritoneal catheter removal, surgical debridement of the abscess and long term antibiotic therapy.

Psoas abscesses are rare clinical entities complicating Crohn's disease (CD). However, psoas abscesses can cause poor outcomes because the diagnosis is frequently delayed due to the non-specific clinical features. Recently, we managed a case of a huge iliopsoas abscess in a 21-year-old man with a 4-year history of CD who presented with a limping gait and flexion contractures of the sacroiliac joint. Notably, the iliopsoas abscess developed during induction treatment with infliximab. The patient was successfully treated with antibiotics, surgical drainage, and a right hemicolectomy. Herein we present the case with a brief review of the literature.

OBJECTIVE: This study was performed to investigate the effects of pioglitazone, an insulin sensitizing agent, on insulin resistance, ovarian function and intraovarian stromal blood flow in patients with polycystic ovarian syndrome (PCOS). MATERIAL AND METHODS: Thirty patients with PCOS, aged 18~34 years, were recruited. Criteria for diagnosis of PCOS were as defined in 2003 Rotterdam consensus. They were treated for 6 months with pioglitazone at a dose of 30 mg/day orally. The hormonal blood profile, fasting serum glucose levels, a glycemic response to 75 g oral glucose tolerance test (OGTT), and an ovarian stromal artery (OSA) blood flow were assessed at baseline and after 6 months of treatment. RESULTS: Eighteen (60.0%) of 30 patients treated with pioglitazone demonstrated a spontaneous ovulation After pioglitazone treatment, fasting insulin concentrations, serum glucose levels after 75 g OGTT significantly decreased (p=0.001, p=0.04, respectively), and fasting glucose to insulin (G/I) ratio significantly increased (p<0.001). The pioglitazone treatment induced a significant reduction in serum LH, testosterone (T) and free T levels (p<0.001, p=0.02, p=0.002, respectively). The resistance index (RI) values of OSA significantly increased after treatment (p<0.001). In analyzing pioglitazone-treated patients according to their body mass index (BMI), nonobese group as well as obese group showed a significant improvement in fasting G/I ratio (p<0.01). The pioglitazone treatment induced a significant reduction in serum LH and free T levels in nonobese group (p<0.001, p<0.05, respectively) as well as obese group (p=0.001, p<0.05, respectively). The RI values of OSA significantly increased in both nonobese and obese groups after pioglitazone treatment (p<0.001, p=0.003, respectively). CONCLUSIONS: Pioglitazone could ameliorate the glycoinsulinemic metabolism, and this beneficial effects of this drug could improve the endocrine-reproductive condition associated with the decrease of ovarian stromal artery blood flow, in both nonobese and obese patients with PCOS.
