We report a case of lymphadenoma arising in the parotid gland. A 53-year-old female patient presented with a mass in the parotid gland. Grossly, it was a well-demarcated solid mass measuring 3 cm in diameter. Microscopic examination revealed many cysts or duct-like structures in the background of the prominent lymphoid stroma, confirming a diagnosis of lymphadenoma. This particular case was thought to have arisen from an intraparotid lymph node. Lymphadenoma is a rare benign neoplasm of the salivary gland with partial resemblance to other salivary gland tumors, such as Warthin's tumor, cystadenoma, sebaceous lymphadenoma or mucoepidermoid carcinoma. Therefore proper recognition of this rare entity is warranted to avoid confusion in the diagnosis.

Conventional abdominoplasty includes the removal of an ellipse-shaped section of abdominal tissue between the umbilicus and mons pubis. However, this method can result in tension of the undermined flap, especially in the midline. To address this problem, we present reverse lip design as a modified method that also has aesthetic advantages. The reverse lip design entails a longer lower flap edge while preserving the triangular tissue in the vascularly stable pubis area. These markings create an image of a reverse lip shape with a cleft at the bottom of the lower markings. After typical lipoabdominoplasty is performed, redundant waist tissues can easily be pulled inward and downward. The reverse lip design abdominoplasty demonstrated no complications and required no further revisions after the procedure. Patients were generally satisfied with the aesthetic improvements in their body shape. They were also able to return to their routine activities approximately 1 week after the operation while wearing a supporting undergarment. This modified abdominoplasty using the reverse lip design reduces low midline tension of the undermined abdominal flap while enhancing body aesthetics with a slimmer waistline, leading to higher patient satisfaction.

The traditional drug for anticoagulation in those with a high risk of thrombosis is a vitamin K antagonist, such as warfarin. On the other hand, this drug has several limitations and hemorrhagic complications. Recently, novel or non-vitamin K-dependent antagonist oral anticoagulants (NOACs) have been developed to solve these problems. This paper presents a case of adaptation of NOAC for a warfarin anticoagulated patient with traumatic ongoing hemorrhages with a discussion of the clinical implications of NOAC.

The pneumatic colorectal injury caused by high pressure compressed air are rare and can be fatal. Herein, we present a case of 45-year-old male who developed sudden onset of severe abdominal pain after cleaning the dust on his pants with high pressure compressed air gun dust cleaner. Emergent exploratory laparotomy was done which findings are a huge rectal perforation with multiple serosal and subserosal tear in sigmoid to splenic flexure of colon. Anterior resection with left hemicolectomy, and temporary transverse colostomy was performed. Postoperative course was uneventful. Recently, prognosis is generally favorable because of prompt diagnosis and emergent surgical management.

Background: Pedicle screw augmentation with bone cement has been experimentally demonstrated to increase the pullout strength. However, the mechanisms of screw loosening are complicated and interacting. Although vertebroplasty augmentation and fenestrated screw augmentation have been compared in many studies, there has been no comparative study on their clinical effects and complications in real clinical settings. We investigated clinical effects of bone cement augmentation of a pedicle screw and differences according to augmentation methods. Methods: Of the total 241 patients who had osteoporosis and underwent posterior pedicle screw fixation without anterior bone graft between January 2010 and December 2016, 132 patients with ≥2 years of radiological follow-up were included in this retrospective study. The patients were divided into group I (unaugmented) and group II (bone cement augmented). Group II was subdivided into II-S group (solid screw augmented) and II-F group (fenestrated screw augmented). The incidence of screw loosening was compared between groups I and II. Cement leakage, screw loosening, and screw fractures were investigated in the subgroups. Results: In total, 36 of 71 (52%, group I) unaugmented cases and 96 of 170 (56%, group II) augmented cases were followed up for ≥2 years. Of the total 78 solid screw augmented cases, 42 (56%) were in II-S group; 54 of the total 92 (59%) fenestrated screw augmented cases were in II-F group. Groups I and II were homogenous regarding demographic characteristics; II-S and II-F groups were also homogenous. The incidence of screw loosening was 50.0% (18/36) in group I and 7.3% (7/96) in group II (p < 0.001). Cement leakage developed in 2 of 42 (4.8%) cases in II-S group and in 5 of 54 (9.3%) cases in II-F group (p = 0.462). Screw loosening developed in 6 of 42 (14.3%) cases in II-S group and in 1 of 54 cases (1.9%) in II-F group (p = 0.041). Screw fracture developed in none of 42 cases in II-S group and in 3 of 54 cases (5.6%) in II-F group (p = 0.254). Conclusions In osteoporotic patients, bone cement augmentation of a pedicle screw decreased the incidence of screw loosening, and fenestrated screw augmentation was more effective than vertebroplasty augmentation.

BACKGROUND AND OBJECTIVES: Ten to twenty percent of children with Kawasaki disease (KD) do not respond to initial intravenous immunoglobulin (IVIG) treatment. If untreated, approximately 15% to 25% of KD patients have complications. The aim of this study was to find useful predictors of responsiveness to initial IVIG treatment in KD. SUBJECTS AND METHODS: We retrospectively reviewed medical records of 91 children diagnosed with KD at Myong Ji Hospital from March 2012 to April 2014. Before and after (24 hours to 36 hours) IVIG treatment, the following laboratory data were obtained: hemoglobin (Hb) level, white blood cell count, proportion of neutrophil, lymphocyte and eosinophil, platelet count, erythrocyte sedimentation rate (ERS), C-reactive protein (CRP), creatine kinase (CK), creatine kinase MB (CK-MB), and N-terminal pro-brain natriuretic peptide (NT-proBNP). Subjects were then divided into two groups: IVIG-responsive or IVIG-resistant. RESULTS: Of 91 patients, 11 (12%) required retreatment. By univariate analysis, before-IVIG laboratory parameters of white blood cell count, % neutrophil, ERS, CRP, sodium, CK, CK-MB, and NT-proBNP were significantly different between IVIG-responsive and IVIG-resistant patient groups. In the after-IVIG laboratory parameters, Hb level, white blood cell count, % neutrophil, % lymphocyte, CRP, CK, CK-MB, and NT-pro-BNP were significantly different between the two groups. While the mean-differences were not statistically significant, fractional change (FC)-CRP and FC-% neutrophil showed significant difference. By multivariate analysis, FC-CRP was confirmed to be an independent predictor for initial IVIG resistance. CONCLUSION: Fractional change-C-reactive protein might be a useful and important value for predicting initial IVIG resistance in KD patients.

BACKGROUND: Kawasaki disease (KD) is an acute inflammation of middle-sized arteries such as the coronary artery. KD is an important disease due to its high mortality rate, which approaches 1-2% without appropriate treatment. Since the various mucocutaneous lesions of KD are related to the dermatologic field, dermatologists should take an interest in this disorder and understand the lesions. OBJECTIVE: To evaluate the characteristics of cutaneous lesions in Korean patients with KD. METHODS: A total of 919 patients with KD were assessed at the department of pediatric cardiology and dermatology, Myongji hospital between January 2006 and December 2010. RESULTS: Of the 919 patients, 566 (61.6%) were diagnosed with typical KD and 353 (38.4%) with atypical KD. KD was most frequent in the 4 year-old group (22.7%), and the ratio of male to female was 1.5:1. Among the mucocutaneous manifestations, erythema of the oropharyngeal mucosa (75.7%) occurred most frequently, followed by polymorphous trunk rash (41.7%), and changes of palms and soles (25.6%). A total of 606 patients (65.9%) with KD had associated diseases as follows: pneumonia (211 patients; 34.8%), pharyngotonsilitis (168 patients; 27.7%), gastroenteritis (132 patients; 21.8%), asthma (15 patients, 2.5%), atopic dermatitis (11 patients, 1.8%). CONCLUSION: Our study shows that change in the lips or oral cavity is the most common mucocutaneous manifestation in both classic and atypical KD. Also, morbiliform rash is the most common pattern of polymorphous rashes. Interestingly, erythema multiforme-like lesions occupied accounted for a considerable portion of KD cases compared to previous studies.

The seat belt is designed for safety in a motor vehicle and should be worn to prevent severe injuries. But, the seat belt itself can be an injury factor in combination with deceleration forces applied to fixation points of mobile viscera. Here, we present a 23-year-man with traumatic transection of the appendix, highly mobile viscera, following seat belt injury.

Acute limb compartment syndrome (ALCS) is defined as compound symptoms resulting from poor oxygenation and decreased nutrition supply to muscles and nerves in a tightly confined compartment. The most common cause of ALCS is tibia fracture, followed by blunt trauma to soft tissue. However, non-traumatic causes are rare. We report an iatrogenic, non-traumatic ALCS case after venoarterial extracorporeal membrane oxygen (VA-ECMO) therapy. A 14-year-old male received VA-ECMO therapy due to cardiorespiratory failure after drowning. Although he had no symptoms during therapy, leg swelling appeared 10 hours after ECMO treatment. Two days after the leg swelling, the patient underwent a fasciotomy. Unfortunately, nerve conduction studies and electromyography showed multiple neuropathies in the lower leg. Despite 2 weeks of rehabilitation with electrical stimulation, an exercise program, and physical therapy, there was no definite change in muscle strength. To our knowledge, this is the first reported case of non-traumatic ALCS after VA-ECMO therapy in Korea.

Hantaan virus is widely distributed among rodent populations in Korea. Two antigenically distinct hantaviruses were isolated from Apodemus agrarius in 1976 and Rattus norvegicus in 1980 in Korea. This study was designed to investigate the serological evidence of hantavirus infection among indegenous wild rodents, which were captured in 11 mountains located in Kyunggi, Kangwon, Chungnan, Chunbug and Kyungnam province of South Korea. A total 252 wild rodents of 3 species were trapped from Myungsung Mt., Chumbong Mt., Kali Mt., Hansuk Mt., Chachil peak, Kyebang Mt., Odae Mt., Kyerong Mt., Kaya Mt., Togju Mt. and Chiri Mt. in 1997. Serologic test for hantavirus infection was performed using hantavirus antigens by indirect immunofluorescent antibody technique. Among 122 Apodemus agrarius, 88 Apodemus peninsulae and 42 Eothenomys regulus; 18 A. agrarius (14.8%), 12 A. peninsulae (13.6%) and 4 E. regulus (9.5%) were immunofluorescent antibody (IFA) positive against hantaan virus. IFA titers 3 Eothenomys regulus sera were higher against puumalavirus than hantaan virus. These data imply that above three species of rodent might be natural reservoirs of hantaviruses in Korea.
