Highly cohesive, form-stable cohesive gel implants were introduced in 1993. This resulted in a paradigm shift in breast augmentation surgery. With the introduction of shaped textured implants, surgeon started to think in terms of shape and dimensions rather than volume and cup size. Basically most aspects of such breast augmentations are different. The way of selecting implants is different. Patient preoperative markings, surgical techniques, postoperative recommendations and results also differ. These are not mere new types of implant, but they represent a new concept in breast augmentation surgery. Surgeons who believe that form stable implants behave in the same way as non-form stable implants will tend to plan, select implants and perform surgery in traditional ways. Unfortunately, they are bound to encounter significantly more complications and problems. These implants are recently available in Korea since 2012 and will provide patients and surgeons with the ability of enhanced outcome and results if used properly; however there needs to be a transition from round cohesive gel implant thought process to a more comprehensive approach for the typical Korean plastic surgeon.

BACKGROUND: Glycemic control is an effective way to reduce the cardiovascular complications of diabetes, but more than half of the adults with diabetes in Korea are improperly controlling their glycemic levels. The purpose of this study is to identify the factors associated with poor glycemic control in type 2 diabetes patients. METHODS: This study analyzed 1,261 subjects ≥30 years old diagnosed with type 2 diabetes who participated in the fifth Korean National Health and Nutrition Examination Survey (2010-2012). Poor glycemic control rates were defined as hemoglobin A1c (HbA1c) level ≥7%. To shed light on the causes of poor glycemic control, socio-demographics, diabetes severity, health status, and health behavior factors were adjusted and logistic regression was done. RESULTS: Of the total 1,261 patients, 53.0% of patients with type 2 diabetes had HbA1c ≥7%. After running a logistic regression model, the odds ratio of poor glycemic control was higher in high school graduates than elementary school graduates; in people living in Chungcheong and Jeolla/Jeju than those living in Seoul; in the group with diabetes for over 5 years had diabetes less than 5 years; in a group with insulin and oral hypoglycemic agent treatment than non-treatment; in a group with hypertriglyceridemia than without hypertriglyceridemia; and in the group with slept less than 6 hours slept 7-8 hours. CONCLUSION: We need a comprehensive public health policy to reduce the poor glycemic control rates in type 2 diabetes patients. We should recognize the education levels, duration of diabetes, diabetes treatment, hypertriglyceridemia, and sleep duration were associated with poor glycemic control.

Brachial plexus block is frequently used for surgery on the upper extremity. Unsuccessful brachial plexus block is usually caused either by injection outside the neurovascular sheath or by incomplete blockade inspite of injection within the neurovascular sheath. Studied by Winnie and Collines suggested that the extent of blockade following injection in the sheath surrounding the brachial plexus also should be directly proportional to the volume of local anesthetic injected. We therefore investigated the extent of blockade using different volume of bupivacaine with supraclavicular approach. The results were as follows. 1) Complete analgesia was observed between the group of 15 ml and 30 ml. 2) The interval of complaint of pain after a single injection ranged from 14.3 to 16.4 hours. Insignifi-cant difference was found between the group of 15 ml and 30 ml (p> 0.1) 3) There was no hematoma, shivering, but there was Horner's syndrome in 13, phrenic N.paralysis in 2, pneumothorax in 1 cases. No general seizure or other side effects were observed. Therefore we come to the conclusion that above the volume of 15 ml is sufficient to brachial plexus block with supraclavicular approach.

Gastroesophageal varices occur in more than half of patients with cirrhosis and the incidence increases as liver function worsens. Although the mortality rate for acute variceal bleeding has decreased with the development of variceal endoscopic hemostasis and administration of vasoactive drugs and prophylactic antibiotics, it still reaches 20%. Therefore, surveillance of variceal occurrence and the prevention of their bleeding is very important in patients with cirrhosis. In patients with liver cirrhosis accompanied by portal hypertension, esophagogastroduodenoscopy should be performed to diagnose varices and stratify their bleeding risk. The interval of endoscopic surveillance is adjusted according to variceal condition and cirrhosis severity. If varices are diagnosed, primary prophylaxis (e.g., non-selective beta-blockers or endoscopic prophylaxis) is required to prevent variceal bleeding. Appropriate treatment, including timely endoscopic hemostasis, should be performed in patients with acute variceal bleeding, and secondary prophylaxis is required to prevent rebleeding. Endoscopic variceal ligation is the recommended endoscopic treatment for acute esophageal variceal bleeding; endoscopic variceal obstruction is usually recommended in patients with gastric varices. To prevent bleeding, endoscopic surveillance should be performed at regular intervals until the varices have been eradicated, and endoscopic followup should be performed periodically even after their disappearance. In this review, we investigate the role of endoscopy in the treatment and management of gastroesophageal varices.
