In patients with unilateral mandibular condyle hyperplasia, whether to perform condylectomy and orthognathic surgical procedures at the same time or orthognathic surgery in two stages for remains controversial. Reported here is a case of facial asymmetry with mandibular condyle hyperplasia, for which condylectomy and orthognathic surgery procedures were performed at the same time. A 28-year-old woman was presented to our department with chief complaints of left deviation of the mandible and right temporomandibular joint (TMJ) noise. Findings obtained in several imaging examinations led to a diagnosis of facial asymmetry associated with right mandibular condyle hyperplasia. Following 3 months of preoperative orthodontic treatment, in October 2018 under general anesthesia the patient underwent a right mandibular condylectomy, Le Fort I osteotomy, right mandibular sagittal split ramus osteotomy, and left mandibular inverted L ramus osteotomy. In examinations up to 3 years after surgery, good results were noted. For this case of severe facial asymmetry with mandibular condyle hyperplasia, early surgery and condylectomy were performed simultaneously to significantly shorten the total treatment time. The effectiveness of a surgery-early approach was confirmed by no postoperative findings indicating abnormalities in the TMJ or retroversion.

It's important that detect early caries of deciduous and permanent teeth to prevent dental caries and prevserve teeth, especially on proximal surface of deciduous teeth. The reason is that their prominent pulp horn lead to pulp treatment easily due to rapid caries progression. There are conventional exploring, visual inspection and radiographic exam for early caries detection. But, the standard method for diagnosing dental caries is subject and cavitation may be accelerated during exploring procedure. Caries can be diagnosed up to 40% mineral loss with radiograph. $DIFOTI^{(R)}$ (Digital Imaging Fiber-Optic TransIllumination) is diagnostic imaging system for early caries detection using fiber-optic illumination. It is possible that remineralize the tooth surface without tooth preparation and conserve the tooth structure by using $DIFOTI^{(R)}$.

Purpose: The aim of this study is to evaluate the feasibility and safety of cardia preserving proximal gastrectomy, in early gastric cancer of the upper third. Materials and Methods: A total of 10 patients were diagnosed with early gastric cancer of the upper third through endoscopic biopsy. The operation time, length of resection free margin, number of resected lymph nodes and postoperative complications, gastrointestinal symptoms, nutritional status, anastomotic stricture, and recurrence were examined. Results: There were 5 males and 5 females. The mean age was $56.5{\pm}0.5$ years. The mean operation time was $188.5{\pm}0.5$ minutes (laparoscopic operation was 270 minutes). Nine patients were T1 stage (T2 : 1), and N stage was all N0. The mean number of resected lymph nodes was $25.2{\pm}0.5$. The length of proximal resection free margin was $3.1{\pm}0.1$ cm and distal was $3.7{\pm}0.1$ cm. Early complications were surgical site infection (1), bleeding (1), and gastro-esophageal reflux disease (1) (this symptom was improved with medication). Late complications were dyspepsia (3) (this symptom was improved without any treatment), and others were nonspecific results of endoscopy or symptom. Conclusions: Cardia preserving proximal gastrectomy was feasible for early gastric cancer of the upper third. Further evaluation and prospective research will be required.

Mucopolysaccharidosis (MPS) I is a rare, progressive and multisystemic disease with insidious initial signs and symptoms, and making an early diagnosis can be a challenge for the first-line general medical practitioner. We report a 6-month-old girl who was brought to our well baby clinic for regular immunization with the manifestations of lumbar gibbus, hirsutism, large Mongolian spots over back and buttock, and mild bilateral legs spasticity noticed by the general pediatrician, and then newly diagnosed with MPS I after referral to the geneticist in time. Her surgical history included inguinal hernia repair at 1 month old, $CO_2$ laser supraglottoplasty for laryngomalacia and tracheostomy due to chronic respiratory failure with ventilator dependence at 2 months old. Understanding and identification of the early signs and symptoms of this disease have the potential to early diagnosis and timely appropriate treatment, which could contribute to a better clinical outcome.

Purpose: The purpose of the study is to evaluate the clinical outcomes of acute achilles tendon rupture patients treated by early mobilization after operative repair. Materials and Methods: In this retrospective study, 12 patients of acute Achilles tendon rupture were surgically treated from May 2001 to November 2002, with follow-up period of at least 6 months. There were 10 men and 2 women, and mean age was 35.9 year. The repair method was single Krackow suture technique. Two to three weeks after the operation, early ROM with removable ankle-foot orthosis(AFO) was started. We used Amer-Lindholm scale for the clinical evaluation and analyzed patient's satisfaction and subjective strength deficit. Results: We had 11 excellent results(92%), and 1 good results(8%). One-leg heel raising was possible in all patients. All the patients returned to the preinjury occupations and 7 patients(58%) reached the preoperative level of sports activities. There was no significant difference in ankle ROM and ankle plantar flexion isokinetic strength compared to contralateral side. There was, no reruptures. Conclusion: Early mobilization proved to be a well tolerated, safe, and effective means for the compliant patient.

Endobronchial ultrasound (EBUS), which enables visualization of lesions beyond the bronchus, broadens the fields of bronchoscopy. Two types of ultrasound, radial and linear, are used for bronchoscopy. Radial EBUS is performed by inserting an ultrasound mini-probe through the working channel of a flexible bronchoscope. Evaluation of the depth of invasion of early endobronchial lung cancers using radial EBUS is useful in deciding endobronchial treatment. A central tumor limited to within the cartilaginous layer is a good indication for endobronchial photodynamic therapy. EBUS-guide sheath (GS) technique is a sampling method assisted by localization of peripheral lesions using EBUS. The diagnostic yield of EBUS-GS method is higher than that of conventional transbronchial biopsy. High diagnostic values of EBSU-GS method are reported even in small (${\leq}2cm$) peripheral tumors. Linear EBUS is used for endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA). EBUS-TBNA has high diagnostic yields in mediastinal staging of lung cancer even in patients having radiologically early stage lung cancers with normal CT or PET findings in the mediastinum. EBUS is a valuable method in evaluating early endobronchial tumors and peripheral small lung cancers and as well as in mediastinal staging.

Taste and odor (T&O) problems in drinking water supplies caused by eutrophication have become increasingly important because aesthetic qualities are the primary measures by which consumers estimate the quality of their drinking water. In order to overcome T&O problem, it is necessary to early detection method for T&O compounds before these compounds enter to water treatment plant. In this background, a early waming device for T&O compounds was developed and its performance tested under different operating condition. According to the experimental results on the adsorption efficiency of T&O compounds, when the raw water flowrate was 5 mL/min, the optimum stripping time and air flowrate were 5 hrs and 0.5 L/min, respectively. Comparison of activated carbon showed that foreign activated carbon was better than domestic activated carbon in terms of adsorption efficiency.

Purpose To evaluate the value of clinicopathologic factors and imaging features of primary breast cancer in predicting early recurrence after the primary treatment. Materials and Methods We enrolled 480 patients who had been followed-up after breast-conserving surgery and adjuvant therapy from January 2010 to December 2014 at our hospital. Early recurrence was defined as recurrence within 3 years after completion of primary treatment, and univariate and multivariate logistic regression analyses were performed to determine the clinicopathologic and imaging predictive factors of early recurrence. Results In the univariate analysis, among the clinicopathologic factors, advanced stage (p = 0.021), high histologic grade (p < 0.001), estrogen receptor negative (p = 0.002), high Ki-67 proliferation index (p = 0.017), and triple-negative breast cancer (p = 0.019), and among the imaging features, multifocality (p < 0.001), vessels in the rim on Doppler ultrasonography (US) (p = 0.012), and rim enhancement (p < 0.001) on magnetic resonance imaging of the breast were significantly associated with early recurrence. In the multivariate analysis, advanced stage [odds ratio (OR) = 3.47; 95% confidence interval (CI) 1.12-10.73; p = 0.031] and vessels in the rim on Doppler US (OR = 3.32; 95% CI 1.38-8.02; p = 0.008) were the independent predictive factors of early recurrence. Conclusion Vascular findings in the rim of the primary breast cancer on Doppler US before treatment is a radiologic independent predictive factor of early recurrence after the primary treatment.

Although surgery was the standard treatment for early gastrointestinal cancers, endoscopic resection is now a standard treatment for early gastrointestinal cancers without regional lymph node metastasis. High-definition white light endoscopy, chromoendoscopy, and image-enhanced endoscopy such as narrow band imaging are performed to assess the edge and depth of early gastrointestinal cancers for delineation of resection boundaries and prediction of the possibility of lymph node metastasis before the decision of endoscopic resection. Endoscopic mucosal resection and/or endoscopic submucosal dissection can be performed to remove early gastrointestinal cancers completely by en bloc fashion. Histopathological evaluation should be carefully made to investigate the presence of risk factors for lymph node metastasis such as depth of cancer invasion and lymphovascular invasion. Additional treatment such as radical surgery with regional lymphadenectomy should be considered if the endoscopically resected specimen shows risk factors for lymph node metastasis. This is the first Korean clinical practice guideline for endoscopic resection of early gastrointestinal cancer. This guideline was developed by using mainly de novo methods and encompasses endoscopic management of superficial esophageal squamous cell carcinoma, early gastric cancer, and early colorectal cancer. This guideline will be revised as new data on early gastrointestinal cancer are collected.
