OBJECTIVE: Soft tissue changes due to orthodontic treatment has large individual variation. Therefore continuous evaluation during treatment is required. Patients with fixed orthodontic appliances often wonder if their lip positions will change after the removal of brackets, but only a few studies exist on this topic. The objective of this study was to evaluate the changes of the lips and perioral soft tissue after bracket removal. METHODS: The sample used in this study was 19 males and 33 females. Cephalometric X-rays were taken at 3 stages - T1 (before debonding), T2 (just after debonding), T3 (1.5 months after debonding). RESULTS: The lower lip was retruded immediately after debonding (T2-T1), and 1.5 months after debonding (T3-T2). The mean amounts of retrusion from the vertical reference plane (sG perpendicular line) were about 0.38 mm for the upper lip and 0.88 mm for the lower lip. Immediately after debonding, lip retrusion of females was greater than that of males. During the post-debonding period, lower lip of males was retruded more than that of females. CONCLUSION: Lips are retruded after bracket removal, and there is no gender difference 1.5 months after debonding.

OBJECTIVE: Miniscrew-assisted rapid palatal expansion (MARPE) is a means for expanding the basal bone without surgical intervention in young adults. Here, we assessed the differences in dental, alveolar, and skeletal measurements taken before (T0), immediately after (T1), and 1 year after (T2) MARPE. METHODS: Twenty-four patients (mean age, 21.6 years) who had undergone MARPE and cone-beam computed tomography at T0, T1, and T2 were included. Changes in the following parameters were compared using paired t-tests: intercusp, interapex, alveolar, nasal floor, and nasal cavity widths; inclination of the first molar (M1) and its alveolus; and thickness and height of the alveolar bone. A linear mixed-effects model was used to determine variables that affected periodontal changes in the M1. RESULTS: MARPE produced significant increases in most measurements during T0–T2, despite relapse of some measurements during T1–T2. The alveolar thickness decreased on the buccal side, but increased on the palatal side. The alveolar crest level at the first premolar moved apically. Changes in the thickness and height of the alveolar bone were affected by the corresponding initial values. CONCLUSIONS: MARPE can be used as an effective tool for correcting maxillomandibular transverse discrepancy, showing stable outcomes 1 year after expansion.

Objective: Variable treatment strategies and protocols have been applied to reduce time durations in the process of acute stroke management. The aim of this study is to investigate the effectiveness of our intra-arterial thrombectomy (IAT) protocol for decreasing door-to-recanalization time duration and improve successful recanalization. Methods: A systemic and endovascular protocol included door-to-image, image-to-puncture and puncture-to-recanalization. We retrospectively analyzed the patients of pre- (Sep 2012–Apr 2014) and post-IAT protocol (May 2014–Jul 2018). Univariate analysis was used for the statistical significance according to variable factors (age, gender, the location of occluded vessel, successful recanalization TICI 2b-3). Independent t-test was used to compare the time duration. Results: Among all 267 patients with acute stroke of anterior circulation, there were 50 and 217 patients with pre- and post-IAT protocol. Age, gender, and the location of occluded vessel have no statistical significance (p＞0.05). In pre- and post-IAT group, successful recanalization was 39 of 50 (78.0%) and 185/217 (85.3%), respectively (p＜0.05). Post-IAT (48.8%, 106/217) group had a higher tendency of good outcome than pre-IAT group (36.0%, 18/50) (p＞0.05). Pre- and post-IAT group showed 61.7±21.4 vs. 25±16.0 (p＜0.05), 102.0±29.8 vs. 82.7±30.4 (min) (p＜0.05), and 79.1±47.5 vs. 58.4±75.3 (p＜0.05) in three steps, respectively. Conclusions We suggest that the application of systemic and endovascular IAT protocols showed a significant time reduction for faster recanalization in patients with LVO. To build-up the well-designed IAT protocol through puncture-to-recanalization can be needed to decrease time duration and improve clinical outcome in recanalization therapy in acute stroke patients.

This is a cross-sectional study to evaluate the serum lipid levels of children living in Pusan in 1996. The distribution of age is from 2 years old to 12 years old. In female children mean total cholesterol is 171.4+/-26.2mg/dl, triglyceride is 104.7+/-50.6mg/dl, HDL-cholesterol is 54.4+/-14.8mg/dl, and LDL-cholesterol is 95.4+/-32.9mg/dl. In male children mean total cholesterol is 167.9+/-25.2mg/dl, triglyceride is 90.6+/-45.5mg/dl, HDL-cholesterol is 55.4+/-11.7mg/dll, and LDL-cholesterol is 94.4+/-23.6mg/dl. The percentile of serum lipid levels is measured in children. The 95th percentile of serum total cholesterol is 210mg/dl in male children, and 214mg/dl in female children. And, the 95th percentile of serum triglyceride is 184mg/dl in male children, and 191mg/dl in female children. And, the 95th percentile of LDL-cholesterol is 133mg/dl in male children, and 135mg/dl in female children. Serum total cholesterol is positively related to age(r=0.18), height(r=0.08), weight(r=0.17), obesity index(r=0.12), and negatively related to father's education level(r=-0.13), mother's education level(r=-0.13). Serum triglyceride is positively related to weight(r=0.23), age(r=0.31) and negatively related to father's education level(r=-0.12), mother's education level(r=-0.18). Serum HDL-C was positively related to mother's education level(r=0.07) and negatively related to height(r=-0.12), weight(r=-0.09). Conclusively, the serum lipid levels of children living in Pusan is generally so high that the family and school must try to control the serum lipid levels.

Esophageal candidiasis is the most common disease among all candida infections of the gastrointestinal tract, and generally develops in immunocompromised patients. The prevalence of esophageal candidiasis has increased in patients undergoing antibiotic therapy, diabetes, adrenal dysfunction, alcohol intoxication, old age, esophageal injury, esophageal stasis, gastric surgery, and acid suppressive therapy. However, the overall prevalence is not higher than that of immunocompromised patients. Gastric candidiasis is uncommon because of the strong acidity of the gastric juices. The most common clinical setting for gastric candidiasis is in patients with neoplastic disease. However, there are some case reports suggesting an increase in the prevalence of gastric candidiasis after gastric ulcer therapy with surgery or acid suppressive agents. Delayed gastric emptying, increased intragastric pH, and reflux of the duodenal contents into the stomach are factors indicative of the pathophysiology of gastric candidiasis after gastric surgery. We encountered a case of aggravated esophageal candidiasis and the formation of a gastric yeast bezoar following a gastric outlet obstruction due to a duodenal stenosis. We herein report this case along with an overview of the relevant literature.

OBJECTIVE: The purpose of our study is to investigate the feasibility of the laparoscopy and compare perioperative outcomes between laparoscopy and laparotomy in pregnant women with non-malignant ovarian tumor. METHODS: Retrospective comparative analysis of 56 pregnant women who underwent laparoscopy or laparotomy due to non-malignant ovarian tumors at Samsung Medical Center, Seoul, Korea, between October 1994 and December 2010 were performed. RESULTS: Among 56 patients, 22 and 34 pregnant women underwent laparotomy and laparoscopy, respectively. There were no statistically significant differences between the two groups about general characteristics including age, gestational age, torsion, surgeon type, pain at diagnosis and clinical outcomes including tocolytics use, operation type, operation time, the ratio of normal full-term vaginal delivery, Apgar score. However, pathological longest tumor size was larger in laparotomy group than laparoscopy group (9.0 cm vs. 5.8 cm; p=0.001) and laparoscopy was related with significantly less estimated blood loss (200 vs. 50 mL; p=0.001) and short hospital days (7 vs. 4 days; p<0.001). CONCLUSION: Laparoscopy for the treatment of non-malignant ovarian tumors in pregnant women is feasible and has benefits such as less estimated blood loss during the surgery and hospital stays when compared with laparotomy. However, laparoscopic adnexal surgery for large tumor size may be still challenging in pregnant women.

OBJECTIVE: Paclitaxel, ifosfamide, and cisplatin have moderate single-agent activity in patients with metastatic or recurrent cancer of the uterine cervix. We administered a combination of these three agents (TIP) to patients with recurrent cervical carcinoma to evaluate its activity. METHODS: Forty-three patients were treated with ifosfamide (I) 1500 mg/m2 intravenously over 3 hours on Days 1-3, paclitaxel (T) 135 mg/m2 as a 3-hour intravenous infusion and cisplatin (P) 50 mg/m2 intravenously over 30 min on Day 1. The chemotherapy was repeated every 3 weeks. RESULTS: Thirty-five patients received at least three courses of treatment and were evaluable for response. Eighteen patients (51.4%) achieved an objective response, including 5.7% complete and 45.7% partial responses. The median time to progression and overall survival for all patients were 8.0 and 16.0 months, respectively. The site of recurrence relative to prior radiation field and histopathology (squamous vs other pathology) did not affect the response rate and survival. Patients treated with another chemotherapy regimen before the initiation of TIP regimen showed lower response rate (28.6% vs 66.6%, p=0.027) and shorter survival (14 month vs 25 month, p=0.028). Grade 3 or 4 toxicity included granulocytopenia in 13% of patients, anemia in 8%, thrombocytopenia in 5%. CONCLUSION: The TIP regimen is relatively well tolerated and moderately active in patients with recurrent carcinoma of the uterine cervix. Patients more likely to benefit are those who received TIP regimen for the first time after recurrence.

OBJECTIVE: To compare laparoscopic surgery with conventional abdominal surgery in patients with early stage endometrial cancer. METHODS: A retrospective review of 63 patients with early stage endometrial cancer managed between March 2003 and May 2005. Two groups were defined whether they had been treated by laparoscopy (case group: n=26) or by laparotomy (control group: n=37). We compared age, body mass index (BMI), hemoglobin change, operation time, number of pelvic lymph nodes, hospital stay, case with adjuvant treatment and recurrence between two groups. RESULTS: There was no statistical difference in characteristics (age, BMI, nulliparity, previous abdominal surgery, FIGO stage, histologic grade). between case and control group. In addition, there was no statistical difference in operation data and outcomes between two groups. Hemoglobin changes were 1.1 g/dL (case group) vs 1.7 g/dL (control group) (p=0.072). Operation time was 131 min vs. 115 min. The numbers of lymph nodes obtained were 8.7 vs 7.7 (right) 9.2 vs. 7.6 (left). Hospital stays were 8.4 vs. 9.2 days. Adjuvant treatment cases were 7 vs. 15. Recurrent case was one in each group. Two patients initially evaluated by laparoscopy were converted to laparotomy due to bleeding and adhesion. CONCLUSION: Laparoscopic surgery for treatment of early endometrial cancer is a safe and effective alternative to laparotomy . However, long-term survival and risk of recurrence have yet to be determined.

OBJECTIVE: The purpose of this study was to evaluate the patients' characteristics and treatment results for 31 granulosa cell tumors (GCTs) of the ovary. METHODS: We retrospectively reviewed the medical records of 31 patients with GCT who received treatment from January, 1997 to April, 2005. They were grouped into 21 adult types, 4 juvenile types and 6 recurrent GCTs. Clinicopathological characteristics, treatment results and follow-up data were investigated from medical records and/or telephone surveys. RESULTS: In adult types, the median age of patients was 42 years (20 to 81 years). The most common present symptom was vaginal bleeding (10/21, 47.6%). All patients with adult type had FIGO stage I with median follow-up of 32 months (5-103 months). No recurrence developed in this group. In juvenile types, the median age was 8 years (2-14 years). Precocious puberty was presented in 2 of 4 (50%). Three had FIGO stage I and one had FIGO stage IIIa. Two patients were given adjuvant chemotherapy with bleomycin, etoposide, cisplatin (BEP) regimens for six cycles. No recurrence was found during median follow-up of 20.5 months (16-27 months). In recurrent GCTs, cytoreductive surgery and adjuvant chemotherapy were given to 5 patients. One patient, who had a disease with multiple liver and multiple lung metastases, was given palliative chemotherapy. All patients were alive, two were clinically in complete response. CONCLUSION: There was no recurrence in adult types and juvenile types, and no dead of disease in recurrent group. However, because of the propensities of GCT to recur years after initial diagnosis and to grow slowly with indolent course, prolonged surveillance with serial physical examination and imaging studies is reasonable.
