Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aorta. The stent was unable to be retrieved into the guide catheter, as it was distorted. A goose neck snare was used successfully to catch the stent in the ascending thoracic aorta and retrieved the stent externally via the arterial sheath.

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a rare case of dislodgement of two intracoronary stents. On withdrawal of two balloon catheters, one with a guide wire was mechanically distorted from the left main (LM) to the proximal left anterior descending artery (LAD) while the other was dislodged from the LM to the ostial left circumflex artery. The stent in the LAD could not be retrieved into the guide catheter using a Goose neck snare, because it was caught on a previously deployed stent at the mid LAD. A new stent was quickly deployed from the LM to the proximal LAD, because the patient developed cardiogenic shock. Both stents, including a distorted and elongated stent, were crushed to the LM wall. Stent deployment and crushing may be a good alternative technique to retrieving a dislodged stent.

BACKGROUND: The prevalence of obesity is increasing year after year in Korean; and gastroesophageal reflux disease(GERD) is increasing in this population as well. The aim of this study is to assess the association between age, body mass index(BMI) and GERD in healthy Korean adults. METHODS: Analysis was done on 1,016 subjects who had not had malignancy, uncontrolled metabolic disease, enteric surgery and organic esophageal disease. They completed a questionnaire that included past history and reflux symptoms. Endoscopy was performed by two gastroenterologists who were not given any patient information. Existence of GERD was determined by the esophageal syndrome criteria of the Montreal guidelines. Subjects were categorized by BMI, initially as: underweight, normal(18.5< or =BMI<25), overweight(25< or =BMI<30) and obese by the WHO criteria, and then as: underweight, normal(18.5< or =BMI<23), overweight(23< or =BMI<25) and obese by the Asian-Pacific criteria. RESULTS: The overall[is this correct] prevalence of GERD in our subjects was 15.5%. Age and sex were not correlated factors for GERD. By the WHO and the Asian-Pacific criteria, GERD was present in underweight(10.0%, 12.1%), normal(13.9%, 14.4%), overweight(18.6%, 13.0%) and obese groups(21.0%, 18.8%). No meaningful association was seen between BMI and GERD in either of the classified groups. Erosive GERD was seen in 83 subjects (8.2%) on endoscopy. The obese(BMI> or =25) group(12.1%) showed a meaningful increment in the prevalence of erosive GERD compared to the non-obese(BMI<25) group(6.2%)(p value 0.002). CONCLUSION: The prevalence of GERD in healthy Korean adult subjects was not closely associated with obesity and age[according to BMI]; however, erosive GERD was found to have a strong association with obesity.

BACKGROUND: Epidermal cysts are commonly occurring masses usually less than 5 cm in diameter, but in predisposed patients, epidermal cysts can grow relatively large due to chronic infection. METHODS: From June 2002 to July 2010, 17 patients received 19 regional perforator-based island flaps to cover defects due to the excision of large epidermal cysts (diameter >5 cm) in the buttocks. Eight patients had diabetes, and seven had rheumatoid arthritis. The pedicles were not fully isolated to prevent spasms or twisting. RESULTS: All the flaps survived completely, except for one case with partial necrosis of the flap, which necessitated another perforator-based island flap for coverage. There were two cases of wound dehiscence, which were re-closed after meticulous debridement. There were no recurrences of the masses during follow-up periods of 8.1 months (range, 6-12 months). CONCLUSIONS: In patients with large epidermal cysts and underlying medical disorders, regional perforator-based island flaps can be the solution to coverage of the defects after excision.

Mature cystic teratomas of the ovary are one of the most common ovarian neoplasms found in reproductive age women. Malignant transformation is an uncommon complication in a mature cystic teratoma of the ovary, usually being reported in about 1-3% of cases. Of malignant transformations, squamous cell carcimona is the most common type and sarcomatous transformation is rare, its prognosis is poor. Adenocarcinoma occurs with less frequency. We experienced a case of squamous cell carcinoma and adenocarcinoma arising in mature cystic teratoma of the ovary, so we present this case with brief review of the literature.

A case of vaginal and cervical adenocarcinoma, mostly of clear cell type, in young women have been associated with intrauterine exposure to diethystillbestrol(DES) or other nonsteroidal estrogenic substances and vaginal adenosis. We have encountered a case of clear-cell adenocarcinoma of the cervix uteri of 27years young house wife, in which there was a history of intrauterine exposure to DES. We presented a case with a brief review of related literature.

Background: This study evaluated changes in nasal airway function following Le Fort I osteotomy with maxillary impaction according to the Nasal Obstruction Symptom Evaluation (NOSE) scale. Methods: This cohort study included 13 patients who underwent Le Fort I osteotomy with maxillary impaction. Nasal airway function was evaluated based on the NOSE scale preoperatively and at 3 months postoperatively. The change in the NOSE score was calculated as the preoperative score minus the postoperative score. If the normality assumptions for changes in the NOSE score were not met, a nonparametric test (the Wilcoxon signed-rank test) was used. Differences in NOSE score changes according to patient characteristics and surgical factors were evaluated using the Kruskal-Wallis test and the Mann-Whitney test. Results: Patients ranged in age from 18 to 29 years (mean±standard deviation [SD], 23.00±3.87 years). Three were men and 10 were women. Eleven patients (84%) had an acquired dentofacial deformity with skeletal class III malocclusion. The preoperative NOSE scores ranged from 40 to 90 (mean±SD, 68.92±16.68), and the postoperative NOSE scores ranged from 25 to 80 (53.84±18.83). The cohort as a whole showed significant improvement in nasal airway function following maxillary impaction (P=0.028). Eleven patients (84%) had either improved (n=8) or unchanged (n=3) postoperative NOSE scores. However, nasal airway function deteriorated in two patients. Patient characteristics and surgical factors were not correlated with preoperative or postoperative NOSE scores. Conclusions Nasal airway function as evaluated using the NOSE scale improved after maxillary impaction.

Background: Excessive bleeding is one of the most severe complications of orthognathic surgery (OGS). This study investigated the associations of intraoperative blood loss and surgical time with the direction of maxillary movement. Methods: This retrospective study involved patients who underwent OGS from October 2017 to February 2020. They were classified based on whether maxillary setback was performed into groups A1 and B1, respectively. Relative blood loss (RBL, %) was used as an indicator to compare intraoperative blood loss between the two groups. The surgical time of the two groups was also measured. Subsequently, the patients were reclassified based on whether posterior impaction of the maxilla was performed into groups A2 and B2, respectively. RBL and surgical time were measured in the two groups. Simple linear and multiple regression analyses were performed. P-values <0.05 were considered to indicate statistical significance. Results: Eighteen patients were included. The RBL and surgical time for the groups were: A1, 13.15%±5.99% and 194.37±42.04 minutes; B1, 12.41%±1.89% and 196.50±46.07 minutes; A2, 13.94%±3.82% and 201.00±39.70 minutes; and B2, 9.61%±3.27% and 188.84±38.63 minutes, respectively. Only RBL showed a statistically significant difference between the two groups (A2 and B2, P=0.04). Conclusions Unlike maxillary setback, posterior impaction of the maxilla showed a significant association with RBL during surgery. When performing posterior impaction of the maxilla, clinicians need to pay particular attention to surgery and postoperative care.

The primary T-cell lymphoma of the stomach is a extremely rare disease, only about 33 cases were described in the literature since 1986. Recent studies have proved a strong relation between Helicobacter pylori infection and several gastric diseases such as peptic ulcer, chronic gastritis, gastric cancer, and lymphoma. We report a case of primary gastric T-cell lymphoma with H. pylori infection in a 63-year-old male who had a history of epigastric fullness for 2 years. Gastroscopy showed a round ulcer of 1cm in size on anterior side of gastric angle. The gastroscopic biopsy revealed diffuse large cell malignant non-Hodgkin' s lymphoma on light microscopic examination, and T-cell immunophenotype with immunohistochemical study. The result of CLOtest was positive. No lymphadeno-pathy was found with chest roentgenogram and computed omography of abdomen and pelvis. Bone marrow examination showed normal finding.

PURPOSE: Both atopy and bronchial hyperresponsiveness (BHR) are characteristic features of asthma. Several BHR studies comparing groups of atopic and nonatopic asthmatics have reported conflicting results. The aim of this study was to compare BHR to indirect stimuli, such as mannitol or exercise, between atopic and nonatopic asthmatics in children. METHODS: We performed a retrospective analysis of data from 110 children with asthma, aged 6–18 years using skin prick tests, and serum total and specific IgE levels. Atopy degree was measured using the sum of graded wheal size or the sum of the allergen-specific IgE. Bronchial provocation tests (BPTs) using methacholine were performed on all subjects. BPTs using indirect simuli, including exercise and mannitol, were also performed. RESULTS: Asthma cases were classified as atopic asthma (n=83) or nonatopic asthma (n=27) from skin prick or allergen-specific IgE test results. There was no significant difference in the prevalence of BHR to mannitol or exercise between atopic and nonatopic asthmatics. Atopic asthma had a significantly lower postexercise maximum decrease in % forced expiratory volume in 1 second (FEV1) (geometric mean [95% confidence interval]: 31.9 [22.9–40.9] vs. 14.0 [9.4–18.6], P=0.015) and a methacholine PC20 (provocative concentration of methacholine inducing a 20% fall in FEV1) than nonatopic asthmatics (geometric mean [95% confidence interval]: 1.24 [0.60–1.87] ng/mL vs. 4.97 [3.47–6.47]) ng/mL, P=0.001), whereas mannitol PD15 (cumulative provocative dose causing a 15% fall in FEV1) was not significantly different between the 2 groups. CONCLUSION: There was no significant difference in the prevalence of BHR to mannitol or exercise between atopic and nonatopic asthmatics in children.
