PURPOSE: In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. MATERIALS AND METHODS: Patients with narrow range of age (21-25. mean 22.8+/-1.3, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon tear, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed 21.2+/-7.3wks after trauma. RESULTS: According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight bearing patterns - increased contralateral sole at P and B - were revealed in 7(58.3%). CONCLUSION: Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.

Purpose: Acute care surgery (ACS) has been shown to improve patient outcome and treatment efficiency in the U.S. ACS was introduced to the Department of Surgery, Yonsei University College of Medicine, Seoul to solve the problems associated with delays in surgical evaluation of non-trauma patients who needed emergency surgery, and to offer exposure to a wide variety of surgical cases to general surgical fellows and residents. The objective of this study was to describe the 10-year experience of the ACS department in a single center. Methods: A retrospective chart review was conducted at the Department of Surgery, Yonsei University College of Medicine, Seoul, for all patients admitted from March 2008 to February 2018. Patients were grouped into either the trauma or non-trauma group, and were further classified according to their diagnosis, and the type of operations they had undergone. Results: There was a total of 2,805 patients, including 1,001 trauma patients and 1,804 non-trauma patients. The average hospital length of stay was 14 days and the total in-hospital mortality rate was 3.6%. Trauma mechanisms included blunt (92.6%), penetrating (7.0%) and burn (0.4%) trauma. The majority of non-trauma patients were admitted for appendicitis (37.1%), followed by cholecystitis (21.7%). There was a total of 1,561 operations conducted. The most frequent operations were appendectomy (38.3%) and cholecystectomy (19.5%), followed by adhesiolysis (7.8%). Conclusion A working ACS department has been implemented in a Korean medical center.

Hypoplastic left heart syndrome is a rare congenital heart disease. This is a universally fatal leison, and approximately 80% of patients die within the first week of life. The diagnosis should be considered in infants, with the sudden onset of heart failure, systemic hypoperfusion and cyanosis. 2 cases of hypoplastic left syndrome are presented with review of related literatures.

BACKGROUND: In congenital heart disease, the lung perfusion through stenosed pulmonary artery is usually decreased. And this decrement of lung perfusion also occurs with diaphragmatic palsy after the operation of congenital heart disease. It is difficult to delineate the amount of lung perfusion in case of combination of pulmonary artery stenosis and diaphragmatic palsy. We examined the change of lung perfusion after the induction of diaphragmatic palsy in rabbits. METHODS: We dissected left phrenic nerves in 20 rabbits to induce left diaphragmatic palsy. The lung perfusion scan was performed with 99mTc-MAA and the movement of diaphragm was examined with fluoroscopy. They were performed as baseline data and on 3rd and 10th day postoperatively. The amount of left lung pefusion before and after diaphragmatic palsy was compared and analysed in 12 rabbits which definitely had diaphragmatic palsy. RESULTS: Weight of the rabbits was 1.65+/-0.26 kg. Left lung perfusion percent was 45.93+/-6.42% before operation and these were 32.48+/-6.09% and 37.62+/-3.39% on the 3rd and 10th postoperative day, respectively. Left lung perfusion was significantly decreased just after diaphragmatic palsy but it was not changed thereafter. The decrement of lung perfusion was not affected by the body weight. The decreased amount of left lung perfusion was reciprocally correlated with the body weight of the rabbits on the postoperative 3rd day but not 10th day. CONCLUSION: Left lung perfusion percent of the rabbits was decreased 7% with the induction of diaphragmatic palsy and the decreased amount was reciprocally correlated with the body weight just after the diaphragmatic palsy was induced.

The characteristics of modern society's trauma is a propensity for multiple and severe trauma, specially, the fatal damage accompanied by facial bone fracture. We observed the malocclusion owing to delayed prompt treatment If the fractured fragments is crushed severely, it is difficult to make them positioned into the normal anatomical states and to fix them tightly. Post-traumatic malocclusion is usually caused by a delay in treatment and inadequate anatomic reduction. Inadequately treated facial bone fractures result in facial disfiguring and functional impairment of mastication and speech.We performed 27 cases of correction of post-traumatic malocclusion between April 1994 and June 1996. We used various operative techniques such as anterior segmental osteotomy, Le Fort osteotomy, maxillary segmental osteotomy and mandibular sagittal split osteotomy. If the malocclusion was due to disarrangement segmental osteotomy. If that malocclusion was attributed to a malpositioned skeletal bone, we take maxillary segmental osteotomy or mandibular sagittal split osteotomy. We acquired the desirable occlusion first followed by a fixation between the mandible and maxillary skeletal bones with the bite block. The aim in the correction of malocclusion was to create a harmony of centric relation and centric occlusion. After operation, intermaxillary fixation with bite block have many advantages in the treatment of malocclusion.

PURPOSE: This study was done to explore the lived experience of pregnancy, childbirth, postpartum and early child rearing in married immigrant women in urban areas. METHODS: Data were collected from February to April, 2011 through in-depth interviews. Nine immigrant women were selected in a metropolitan area through the purposive and snowball sampling method. After obtaining IRB permission and informed consent from the participants, all interviews were recorded with MP3 recorder and transcribed for analysis. Using the phenomenological approach, data collected through in-depth interviewing were analyzed following Colaizzi style. RESULTS: Data analysis revealed 4 categories and 10 themes related to pregnancy, childbirth, postpartum and early child rearing of married immigrant women in urban areas. These four categories were 'A clumsy foreigner's life with nostalgia', 'Crisis in the crisis', 'Unprepared for motherhood', and 'Living together with new family without regrets'. It was a common finding that they were not ready to be mothers because of the very short time for adjustment in Korea. Compared to rural, immigrant women urban women had various in social support systems. CONCLUSION: The results indicate that adequate education is needed for immigrant women regarding motherhood, and that this education should be culturally appropriate for these women.
