Pierre Robin sequence (PRS) is characterized by the triad of micrognathia, glossoptosis, and airway obstruction. PRS does not have a single pathogenesis, but rather is associated with multiple syndromes. This report presents the case of a 35-year-old woman with PRS and scoliosis. Among the syndromes related to PRS, cerebro-costo-mandibular syndrome (CCMS), which is characterized by posterior rib gap defects and vertebral anomalies, was suspected in this patient. However, no posterior rib gap defect was detected on radiological examinations. Although over 80 cases of CCMS have been reported to date, few cases of PRS with scoliosis alone have been reported. Therefore, this report demonstrated the clinical, radiological, and cephalometric characteristics of an adult patient with PRS and scoliosis, but without rib anomalies.

There appears to be significant problems remained in the treatment of thoracic empyema inspire of the more potent broad spectrum antimicrobial agents available and improved surgical managements. Clinical analysis of 60 patients of thoracic empyema was done who received major and/or minor surgical intervention at the Dept. of Thoracic and Cardiovascular Surgery, Korea University Hospital in the period of 3 years from May 1973 to July 1976. Following was the results: 1. Male was predominent to female with the ratio of 2.16 to 1, and adult to infant was 2.75: 1. 2. Most frequent predisposing factors of thoracic empyema in infancy and childhood was pneumonia [38.3%], and in adult was pulmonary tuberculosis [36.7%]. 3. Cardinal symptoms were dyspnea, fever, chest pain and productive cough etc. 4. Positive result of bacteriological culture study was reported in 26. 7%, and among them, Staph. aureus [10%], Diplo. pneumonia [3.3%], Streptococcal group [1.7%], Pseu. aeruginosa [1.7%], Paracolon bacilli [1.7%] and others [8.3%] in respectively. No growth of pathologic organism was reported in 60.0%, and not requested in 13.3%. Among the negative group, tuberculosis was confirmed on pathological tissue slide in half and other half was not determined bacteriologically and pathologically. 5. Surgical treatment was performed to the almost all of the patients with closed thoracostomy [48.3%], empyemectomy [28.3%], empyemectomy with pulmonary resection [11.7%] and others [I1.6%] in respectively with favorable results. 6. Mortality rate was 8.3% [5 cases], each one with lung cancer, diabetes mellitus, respiratory insufficiency, sepsis and another, two months old infant with asphyxia.

Pulmonary hamartoma is often incidental, asymptomatic finding on routine chest roentgenogram. It has been considered a congenital malformation. Since the original description by Albrecht in 1908, it has been classified into two types, a small, fibrocartilaginous mass in adults, and a cystic lobar mass in infants. We experienced two cases of pulmonary hamartoma which proved to be the adult form of hamartoma. One was located in left upper lobe of a 58 year old male patient, the other was located in the perihilar region of the right middle lobe of a 38 year old male patient. The former case was treated by wedge resection: the latter by right middle lobectomy and the postoperative courses of both cases were very good and without complication.

Diphyllobothrium latum infections in 4 young Korean men detected from 2008 to 2012 are presented. Three were diagnosed based on spontaneously discharged strobila of the adult worm in their feces, and 1 case was diagnosed by finding the worm at colonoscopy examination in a local clinic. The morphologic characteristics of the gravid proglottid and eggs were consistent with D. latum. All patients were treated with praziquantel 15 mg/kg, and follow-up stool examinations were done at 2 months after the medication. The main clinical complaints were intermittent gastrointestinal troubles such as indigestion, abdominal distension, and spontaneous discharge of tapeworm's segments in their feces. The most probable source of infection was the flesh of salmon or trout according to a patient's past history. These are the 45th to 48th recorded cases diagnosed by the adult worm in the Republic of Korea since 1971.

This paper reports an analysis of cyclist accident cases with respect to passenger vehicles on Korean roads. A typology based on Initiative for the Global Harmonization of Accident Data (iGLAD) code book is applied to a traffic accident analysis system(TAAS), which has the real-world crash data on Korea roads, to understand the accident scenarios in more detail and efficiently. Similarly this typology has been used for Germany In-Depth Accidents Study (GIDAS) as well. The accident data analysis with consideration of the typology of Korean road conditions may prioritize traffic safety issues regarding cyclists and is aimed to develop an Automatic Emergency Braking (AEB) system for cyclist. In summary, this paper characterizes and analyzes the scenarios of cyclist crashes with passenger car. The most common accident scenarios on Korean roads are Car-to-Bicyclist Nearside Adult (CBNA) and Car-to-Bicyclist Longitudinal Adult (CBLA), which are more than 86% of total accidents cases. Therefore, it is inferred that AEB cyclist system should include these accident types in the operational design domain to reduce more fatality in Korea.

Nine cases of human infection with Strongyloines stercornlis are reported among patients admitted to the Seoul Paik and Sang-Kye Paik Hospitals, Inje University, from April 1990 to Junuary 1992. The Patients, 7 males and 2 females acted between 50 and 70, either had the history of long term use of steroids for management of arthritis, or were complicated with other chronic diseases such as hypertension, liver diseases, psychotic disorders, and gastrointestinal problems. All of the nine patients revealed rhabditoid larvae of S. stercorolis in fecal examination. A 57-year-old woman who complained of arthritis and abdominal discomfort, was treated with albendazole and mebendazole, and on the 4th and 5th treatment day 220 parasitic adult females were collected from the diarrheal stool. The patient had a long history of administration of steroids for treatment of arthritis, and seems to have suffered from hyperinfection syndrome due to autoinfection with S. stercordis. This is the 3rd report on the recovery of parasitic adult females of S. stercoraLis in Korea.

Objective : We assessed the surgical results of bipolar release in 31 adult patients with uncorrected congenital muscular torticollis (CMT) and more than 12 months of follow-up. Methods : Thirty-one patients underwent a bipolar release of the sternocleidomastoid muscle (SCM) and were retrospectively analyzed. The mean follow-up period was 14.9 months (range, 12-30). The mean age at time of surgery was 30.3 years (range, 20-54). Patients were evaluated with a modified Lee's scoring system, cervicomandibular angle (CMA) measurement, and a global satisfaction rating scale using patient self-reporting. Results : The modified Lee's scoring system indicated excellent results in 4 (12.9%) patients, good in 18 (58.1%), and fair in 9 (29.0%) at the last follow-up after surgery. The improvements in neck movement and head tilt were statistically significant (p<0.05). The preoperative mean CMA was $15.4^{\circ}$ (range, 5.4-29.0), which was reduced to a mean of CMA of $6.3^{\circ}$ (range, 0-25) after surgery (p<0.05). The global satisfaction rating scale was 93.7% (range, 90-100). A transient sensory deficit on the ipsilateral lower ear lobe was noted in three cases. No significant permanent complications occurred. Conclusion : Bipolar release of the SCM is a safe and reliable technique for the treatment of CMT in adults.

Purpose: Management of pediatric subtrochanteric femur fractures (SFFs) is difficult. The aim of this study was to evaluate the outcomes of adolescent SFFs treated with adult proximal humeral locking plates (PHLPs). Materials and Methods: A retrospective analysis of 18 adolescents (11 male, 7 female) with a diagnosis of SFF who underwent internal fixation with a PHLP was conducted. Data regarding injury mechanism, fracture pattern, and time to union were recorded for all patients. In addition, a clinical and functional evaluation of patients was performed using the Harris hip score (HHS), Iowa hip score (IHS), modified Merle d'Aubigne-Postel score (MMAPS), Flynn criteria, and hip range of motion (ROM). Results: The mean age of the patients was 12.72±2.05 years (range, 10-16 years). Radiological observation was performed for evaluation of five different injury mechanisms and different fracture patterns in patients. The mean postoperative HHS was 92.27±5.61, the mean IHS was 90.88±6.46, and the mean MMAPS was 17.22±0.94. According to the Flynn criteria, excellent results were achieved in 14 cases and satisfactory results were obtained in four cases. Measurements of the patients' mean hip ROM values were as follows: 17.77±3.52° in extension, 115.27±6.74° in flexion, 43.05±3.48° in abduction, 27.50±4.28° in adduction, 42.22±4.60° in internal rotation, and 42.22±3.91° in external rotation. Conclusion: Surgery performed on adolescent patients using an adult PHLP showed good, safe results. Therefore, it should be considered as an alternative option.

Purpose: Despite of the popular use of the reconstruction plate for the fixation of clavicular shaft fractures, some disadventages have been raised such as long period of immobilization, long skin incision, loosening of plate and screws, and increased chance of nonunion due to severe periosteal injury. Thus, the authors have performed intramedullary multiple Steinmann pins fixation that could reduce the disadvantages of plate fixation in order to compare the treatment results between the two groups. Materials & Methods: From 1994. Jan. to 1997. Dec. the department of orthopaedic surgery of the Kwak's hospital treated operatively for 56 cases of the clavicular shaft fractures in adult. 39 cases of them were treated with the plate fixation and 17 cases with the intramedullary multiple Steinmann pins fixation(SP group). Reconstruction plates(Plate group) were used for 26 out of 39 patients treated with plate fixation. Among the Plate group and SP group, each 15 cases were selected by age and sex and compared each other according to the bone union time, union rate, complication, and functional results. The follow-up period was 12 months at the shortest and 48 months at the longest and the average was 16 months. Results: The Plate group showed that the bone union time was 7 weeks and the bone union rate was 93%. The SP group showed 6.5 weeks and 100% respectively. In complication, the Plate group had 1 case of loosening of plate and screws and delayed union; SP group had 1 case of pin migration. The functional results according to Kang's criteria, 87% of the Plate group and 93% of the SP group showed good or excellent. Conclusion : The SP group showed very comparable results in terms of the bone union time, bone union rate, complication, and functional results comparing to the Plate group. The intramedullary multiple Steinmann pins fixation showed several advantages over the reconstruction plate fixation, which were simple operative technique, easy removal of pins, being able to perform immediate postoperative full range of motion exercise. Therefore, the intramedullary multiple Steinmann pins fixation is thought to be one of the useful operative techniques in treatment of the clavicular shaft fractures in adult.

Treatment of mandibular coronoid process hyperplasia (MCPH) has been described and explored in the literature. This systematic review aims to provide a comprehensive overview of the surgical and non-surgical treatment options for MCPH in pediatric and adult populations. Three databases were searched for treatment of MCPH patients (MEDLINE, Embase, and Web of Science). Two reviewers selected case reports and case series based on titles and abstracts. Finally, 55 studies reporting a total of 127 cases were included for qualitative synthesis and data extraction. The mean age at symptom onset was 15.6 years, while the mean age at diagnosis was 23.5 years. Of the included cases, 83.7% were male, and the condition was bilateral in more than 81% of the cases. Coronoidectomy was performed in 82.7% of the included cases, while coronoidotomy was performed in 3.9% of the cases. In 85.0% of the surgically treated cases, the approach was intraoral. The mean maximal intraoperative mouth opening was 38.1 mm compared with 16.5 mm at diagnosis. The mean maximal postoperative mouth opening was 35.3 mm, and the mean follow-up period was 16.3 months. Maximum mouth opening was achieved intraoperatively, and non-surgical treatment after surgery aims to reduce the risk of relapse. Additional research with a higher level of evidence is necessary to confirm these findings.
