Saengjihwangeum-ja (SJHEJ) was recorded in DongEuiBoGam as being able to be used for treatment of Sogal whose concept had been applied to Diabetes Mellitus (DM). Modification of proteins by long term circulation of glucose leads to the formation of advanced glycation end product(AGE). Recent immunological studies demonstrated that ligation of AGE play an important role in the development of diabetic complications including atherosclerosis, which includes activation, adhesion, and migration of monocytes. Also, AGE and Maillard reaction product(MRP) could augment monocyte inflammatory responses via ligation of AGE receptor. In this study, the effects of SJHEJ extracts on the expression of inflammatory response-related genes such as tumor necrosis factor-$\alpha$, monocyte chemoattractant protein-1, interferon-g-inducible protein-10, and cyclooxygenase-2 in the human monocyte cell line, THP-1 cells. Reverse transcriptase-polymerase chain reaction revealed that SJHEJ had inhibitory effects on the expression of the TNF-a, MCP-1, IP-10, COX2, IL-1b genes in MRP-induced THP-1 cells. Treatment with SJHEJ had reduced reactive oxygen production in THP-1 cells stimulated by MRP. These inhibitory effects might be exerted via prevention of oxidative stress in activated monocytes. In addition, radical scavenging activity of SJHEJ was increased. These results suggest that SJHEJ has a beneficial effects for improve diabetic vascular complication.

Background: Nucleoplasty is a minimally invasive spinal surgery using a $Coblation^{(R)}$ technique that creates small voids within the disc. The purpose of this study was to evaluate the efficacy of cervical nucleoplasty in patients with cervical disc disorder. Methods: Between March 2008 and December 2009, 22 patients with cervical disc disorders were treated with cervical nucleoplasty after failed conservative treatment. All procedures were performed under local anesthesia, and fluoroscopic guidance and voids were created in the disc with the $Perc^{TM}$ DC Spine $Wand^{TM}$. Clinical outcomes were evaluated by the Modified Macnab criteria and VAS score at preprocedure, postprocedure 1 month, and 6 months. Results: Six patients had one, eight patients had two and eight patients had three discs treated; a total of 46 procedures was performed. Mean VAS reduced from 9.3 at preprocedure to 3.7 at postprocedure 1 month and to 3.4 at postprocedure 6 months. There was no significant complication related to the procedure within the first month. Outcomes were good or excellent in 17/22 (77.3%) cases. Postprocedure magnetic resonance imaging was acquired in two patients after two months showing morphologic evidence of volume reduction of protruded disc material in one patient but not in the other. Conclusions: Percutaneous decompression with a nucleoplasty using a $Coblation^{(R)}$ technique in the treatment of cervical disc disorder is a safe, minimally-invasive and less uncomfortable procedure, with an excellent short-term clinical outcome.

Objectives: Medically compromised patients often fear required dental surgical procedures that can increase the risk of medical emergency when combined with reduced tolerance for stress. A stress reduction protocol (SRP) helps doctors minimize treatment-related stress and improves patient management with minimum complications. Diabetes and co-morbid hypertension carry 4-fold risk of aggravation of cardiovascular emergencies and 7.2-fold risk of mortality. Diabetic neuropathy can result in difficult diagnosis of myocardial infarction and reduces chances of surviving a myocardial infarction compared with a non-diabetic person. The aim of the study was to assess the feasibility of a protocol for management of patients having both diabetes and hypertension who required minor oral surgery to minimize the rate of cardiovascular emergencies. Materials and Methods: A prospective study was conducted in 140 patients having both diabetes and hypertension who required minor oral surgical procedures. A systematic approachable protocol was designed for management of such patients. Results: Among 140 patients, 6 patients (4.3%) had cardiovascular complications, while 3 patients (1 with syncope and 2 with hypertension) did not require any intervention other than observation. Two patients were managed with aspirin and nitroglycerin, and 1 patient had possible myocardial infarction (overall incidence 0.7%) with chest pain, S-T segment elevation on electrocardiogram, and troponin level of 0.60 ng/mL. Conclusion: The proposed protocol helps to improve management of patients having both diabetes and hypertension. We recommend that patients with uncontrolled diabetes and uncontrolled hypertension and/or patients having history of cardiovascular complication should be treated in a medical facility with a readily available cardiology unit. This facilitates prompt response to emergency and instant implementation of treatment, helping to reduce morbidity and mortality.

Recurrence is the most common complication after shoulder instability surgery, and the main causes of the postoperative recurrence of instability are trauma, misdiagnosis, and technical errors. The risk factors of recurrence may be classified as patient related, anatomical or technical. Causes of failure should be thoroughly evaluated by meticulous history taking, physical examination, and imaging studies, and followed by proper treatment of pathologic lesions. Nonoperative treatment should be considered initially in cases of recurred instability after shoulder instability surgery, but if this fails, repeated recurrence is prevented by performing appropriate anatomical reconstruction of ruptured Bankart lesions, capsular laxities, glenoid deficiencies and humeral head bone defects.

Background: There is inadequate information on the validation of diabetic microvascular complications in the Korean National Health Insurance Service data set. We aimed to validate the diagnostic algorithms regarding the nephropathy, neuropathy, and retinopathy of diabetes. Methods: From various secondary and tertiary medical centers, we selected 6,493 patients aged ≥ 40 years who were diagnosed with diabetic microvascular complications more than once based on codes in the 10th version of the International Classification of Diseases (ICD-10). During 2019 and 2020, we randomly selected the diagnoses of 200 patients, 100 from each of two hospitals. The positive predictive value (PPV), negative predictive value, error rate, sensitivity, and specificity were determined for each diabetic microvascular complication according to the ICD-10 codes, laboratory findings, diagnostic studies, and treatment procedure codes. Results: Among the 200 patients who visited the hospital more than once and had the diagnostic codes of diabetic microvascular complications, 142, 110, and 154 patients were confirmed to have the gold standard of diabetic nephropathy (PPV, 71.0%), diabetic neuropathy (PPV, 55.0%), and diabetic retinopathy (PPV, 77.0%), respectively. The PPV and specificity of diabetic nephropathy (PPV, 71.0-81.4%; specificity, 10.3-53.4%), diabetic neuropathy (PPV, 55.0-81.3%; specificity, 66.7-76.7%) and diabetic retinopathy (PPV, 77.0-96.6%; specificity, 2.2-89.1%) increased after combining them with the laboratory findings, diagnostic studies, and treatment procedures codes. These change trends were observed similarly for both hospitals. Conclusions: Defining diabetic microvascular complications using ICD-10 codes and their related examination codes may be a feasible method for studying diabetic complications.

The treatment of breast cancer has seen great success in the recent decade. With longer survivorship, more attention is paid to function and aesthetics as integral treatment components. However, breast cancer-related lymphedema (BCRL) remains a significant complication. Immediate lymphatic reconstruction is an emerging technique to reduce the risk of BCRL, the Lymphatic Microsurgical Preventive Healing Approach (LYMPHA) being the most widely used approach. Despite promising results, it is often difficult to find suitably sized recipient venules and perform the micro-anastomoses between mismatched vessels deep in the axilla. Moreover, high axillary venous pressure gradients and potential damage from radiotherapy may affect the long-term patency of the anastomoses. From an ergonomic point of view, performing lymphaticovenular anastomosis in the deep axilla may be challenging for the microsurgeon. In response to these limitations, we modified the technique by moving the lymphatic reconstruction distally-terming it distally based LYMPHA (dLYMPHA). A total of 113 patients underwent mastectomy with axillary clearance in our institution from 2018 to 2021. Of these, 26 underwent subsequent dLYMPHA (Group 2), whereas 87 did not (Group 1). In total, 17.2% (15 patients) and 3.84% (1 patient) developed BCRL in Groups 1 and 2, respectively (p = 0.018). Lymphatics and recipient venules suitable for anastomoses can be reliably found in the distal upper limb with better size match. A distal modification achieves a more favorable lymphaticovenular pressure gradient, vessel match, and ergonomics while ensuring a comparably low BCRL rate.

Objective : Essential hyperhidrosis is a pathological condition of excessive sweating beyond that required to cool the body, though poorly understood, originating from a dysfunction of the sympathetic nervous system. Thoracoscopic sympathectomy is the most popular treatment for upper limb hyperhidrosis, because it is a safe, effective, minimally invasive, and time-saving method. However, the common complication is the compensatory hyperhidrosis in other areas of the body, notably on the back, chest, abdomen, and buttocks. Compensatory hyperhidrosis is severe enough for some people, especially those living in a warm climate or engaging in heavy physical activities, to regret ever having had operation. The pathophysiological mechanisms underlying compensatory hyperhidrosis are incompletely understood, even though it is thought to be a truly compensatory feature related to thermoregulation of the body. Materials and Methods : we studied the clinical features of total 233 patients who were diagnosed as essential hyperhidrosis and treated with thoracoscopic sympathectomy or sympathicotomy from March 1992 to July 2000. Results : The success rate of thoracoscopic sympathetic surgery(sympathectomy or sympathicotomy) was 98.7%. The global rate of compensatory hyperhidrosis was 77% ; 84% in group T2, 3 sympathectomy, 76% in group T2 sympathectomy, 43% in group T2, 3 sympathicotomy and 59% in group T2 sympathicotomy. The rate of embarrassing or disabling compensatory sweating was significantly higher in T2 sympathectomy and in T2, 3 sympathectomy than in T2 sympathicotomy and T2, 3 sympathicotomy with significancy in statistic analysis(p<0.01). The precipitating factors of compensatory hiperhidrosis, including heat(warm weather), anxiety, stress, and exertion were noted. The compensatory hyperhidrosis was the main cause of patient dissatisfaction after thoracoscopic sympathectomy. Conclusion : The degree of compensatory hyperhidrosis is closely related to the extent of thoracic sympathectomy.

Objective : Retrospective analysis to compare the effect and complication of epidural patient-controlled analgesia (epidural PCA) with intravenous patient-controlled analgesia (IV PCA) for the treatment of the post-operative pain after posterior lumbar instrumented fusion. Methods : Sixty patients who underwent posterior lumbar instrumented fusion for degenerative lumbar disease at our institution from September 2007 to January 2008 were enrolled in this study. Out of sixty patients, thirty patients received IV PCA group and thirty patients received epidural PCA group. The pain scale was measured by the visual analogue scale (VAS) score. Results : There were no significant difference between IV PCA group and epidural PCA group on the PCA related complications (p=0.7168). Ten patients in IV PCA group and six patients in epidural PCA group showed PCA related complications. Also, there were no significant differences in reduction of VAS score between two groups on postoperative 2 hours (p=0.9618) and 6 hours (p=0.0744). However, postoperative 12 hours, 24 hours and 48 hours showed the significant differences as mean of reduction of VAS score (p=0.0069, 0.0165, 0.0058 respectively). Conclusion : The epidural PCA is more effective method to control the post-operative pain than IV PCA after 12 hours of spinal fusion operation. However, during the first twelve hours after operation, there were no differences between IV PCA and epidural PCA.

Objective : Shunt-dependent chronic hydrocephalus (SDCH) is known to be a major complication associated with aneurysmal subarachnoid hemorrhage (aSAH). Old age is known to be one of numerous factors related to the development of SDCH. This study investigated whether postoperative cisternal drainage affects the incidence of SDCH and clinical outcome in elderly patients with aSAH. Methods : Fifty-nine patients participated in this study. All patients underwent aneurysmal clipping with cisternal cerebrospinal fluid (CSF) drainage. Clinical variables relevant to the study included age, sex, location of ruptured aneurysm, CT finding and clinical state on admission, clinical outcome, and CSF drainage. We first divided patients into two groups according to age (<70 years of age and ${\geq}70$ years of age) and compared the two groups. Secondly, we analyzed variables to find factors associated with SDCH in both groups (<70 years of age and ${\geq}70$ years of age). Results : Of 59 patients, SDCH was observed in 20 patients (33.9 %), who underwent shunt placement for treatment of hydrocephalus. Forty seven percent of cases of acute hydrocephalus developed SDCH. In the elderly group (${\geq}70$ years of age), the duration and amount of CSF drainage did not affect the development of chronic hydrocephalus. Conclusion : In elderly patients, although the incidence of SDCH was significantly higher, clinical outcome was acceptable. The duration and the amount of cisternal drainage did not seem to be related to subsequent development of chronic hydrocephalus within elderly patients aged 70 or older.

Objective : Subthalamic nucleus (STN) deep brain stimulation (DBS) is an effective treatment of choice for patients with advanced idiopathic Parkinson's disease (PD) who have motor complication with medication. The objectives of this study are to analyze long-term follow-up data of STN DBS cases and to identify the factors related to outcomes. Methods : Fifty-two PD patients who underwent STN DBS were followed-up for more than 3 years. The Unified Parkinson's Disease Rating Scale (UPDRS) and other clinical profiles were assessed preoperatively and during follow-up. A linear regression model was used to analyze whether factors predict the results of STN DBS. We divided the study individuals into subgroups according to several factors and compared subgroups. Results : Preoperative activity of daily living (ADL) and the magnitude of preoperative levodopa response were shown to predict the improvement in UPDRS part II without medication, and preoperative ADL and levodopa equivalent dose (LED) were shown to predict the improvement in UPDRS part II with medication. In UPDRS part III with medication, the magnitude of preoperative levodopa response was a predicting factor. Conclusion : The intensity of preoperative levodopa response was a strong factor for motor outcome. And preoperative ADL and LED were strong factors for ADL improvement. More vigorous studies should be conducted to elucidate how levodopa-induced motor complications are ameliorated after STN DBS.
