Background/Aims: Endoscopic mucosal resection (EMR) is the primary treatment for duodenal adenomas; however, it is associated with a high risk of perforation and bleeding, especially with larger lesions. The goal of this study was to demonstrate the feasibility and safety of endoscopic suturing (ES) for the closure of mucosal defects after duodenal EMR. Methods: Consecutive adult patients who underwent ES of large mucosal defects after EMR of large (>2 cm) duodenal adenomas were retrospectively enrolled. The OverStitch ES system was employed for closing mucosal defects after EMR. Clinical outcomes and complications, including delayed bleeding and perforation, were documented. Results: During the study period, ES of mucosal defects was performed in seven patients in eight sessions (six for prophylaxis and two for the treatment of perforation). All ES sessions were technically successful. No early or delayed post-EMR bleeding was recorded. In addition, no clinically obvious duodenal stricture or recurrence was encountered on endoscopic follow-up evaluation, and no patients required subsequent surgical intervention. Conclusions: ES for the prevention and treatment of duodenal perforation after EMR is technically feasible, safe, and effective. ES should be considered an option for preventing or treating perforations associated with EMR of large duodenal adenomas.
Objective : Venous thromboembolism (VTE) after spinal surgery affects a patients' postoperative recovery and also carries a mortality risk. Some studies recommended chemical prophylaxis for high-risk patients and for those after complex spinal surgeries. However, chemoprophylaxis for VTE in spinal surgery is underemployed and there is no agreement on the use of VTE prophylaxis in spinal surgery. The aim of this study was to document the incidence of VTE after an elective instrumental spinal surgery, among those receiving preoperative chemoprophylaxis as compared with patients who did not receive it. Methods : This study was carried out on eighty-nine patients allocated randomly to receive either low molecular weight heparin (LMWH) or no prophylaxis before elective instrumental spinal surgery. All patients received postoperative compression stockings. A compression Doppler ultrasonography was performed for all patients to detect postoperative deep vein thrombosis. In addition, further imaging studies were performed for patients suspected of VTE. Results : Three (3.3%) patients were diagnosed with VTE. One of them had received preoperative chemoprophylaxis. There were no significant difference in incidence of VTE between the two groups (p>0.95; 95% confidence interval, 0.06-8.7). Laterality of gender and postsurgical recumbence duration were all independent predictors of VTE (p=0.01 and p<0.001, respectively). Conclusion : The difference in the incidence of thromboembolic complications between the two groups was not significant. Moreover, we found that preoperative prophylactic LMWH injection has no major bleeding complications altering postoperative course; still, the issue concerning the initiation time of chemoprophylaxis in spinal surgery remains unclear.
Gastrointestinal complications, especially duodenal complication after cardiopulmonary bypass are rare, but often fatal. We experienced 1 case of duodenal ulcer bleeding and 2 cases of duodenal ulcer perforation developing after cardiopulmonary bypass from August 1994 to April 1996. In the case of duodenal ulcer bleeding, palpitation, dizziness, tachycardia and melena were the clues leading to diagnosis, and in the cases of perforation, abdominal distension with pain, tachycardia, hypotension, oliguria were the clues. Duodenal perforations were diagnosed by abdominal paracentesis. The patient with duodenal bleeding was treated by H-2 receptor antagonist, antacids and transfusion. And emergency laparotomy was required for the patients with duodenal perforation. In addition to ulcer prophylaxis including H-2 receptor antagonist and antacids, a high index of suspicion and timely surgery are necessary for early diagnosis and appropriate treatment of duodenal complication developing af er cardiopulmonary bypass.
Purpose : The purpose of this clinical study was to evaluate the effect of chelating and deproteinizing agent containing dental conditioning gel on alleviation of peri-implant mucosa inflammation. Methods: 36 patients with functionally loaded implants for at least 1 year and have clinical signs of peri-implant mucositis were recruited. At baseline, all implants received subgingival prophylaxis with ultrasonic scaler. In the test group, patients were provided a chelating and deproteinizing agent dental conditioning gel (Clinplant$^{(R)}$) and were given instructions to applicate it around the implants using an interdental brush for 2 weeks. Chlorhexidine and saline were provided to the positive control group and negative control group, respectively. The modified sulcus bleeding index (mSBI), modified plaque index (mPI), and probing pocket depth (PPD) were evaluated at baseline, 1 week, and 2 weeks. Results: In the Clinplant$^{(R)}$ and chlorhexidine group, mSBI (-0.81, -0.85 respectively; p<0.01), mPI (-0.46, -0.5 respectively; p<0.01), and PPD (-0.58, -0.48 respectively; p<0.01) at 2 weeks were significantly reduced from baseline. In the saline group, all the clinical parameters were reduced but there was no statistical significance. The saline may be attributed to the influence of prophylaxis at baseline. Conclusions: The present study demonstrated the beneficial clinical effects of chelating and deproteinizing agent containing dental conditioning gel to decrease peri-implant mucosa inflammation equivalent to chlorhexidine. This dental conditioning gel might be useful for alleviation of peri-implant mucosa inflammation.

Aplastic anemia (AA) is a serious hematologic disease characterized by hypocellular bone marrow and deficient production of erythrocytes, granulocytes and platelets. Serious complications such as uncontrolled bleeding and bacteremia can occur. A case of severe AA are presented with dental considerations. A 4-year-old boy had been referred from Seoul National University Hospital for dental examination before the hematopoietic stem cell transplantation (HSCT). Treatments were planned under general anesthesia, due to the poor compliance. Following medical consult, dental treatments were performed after platelet transfusion and antibiotic prophylaxis. Postoperatively, neither significant bleeding nor complictation was observed. On the time of the treatment planning. the anesthesiologist and dentist should perform a complete hematological assessment. It is imperative not only platelet counts but also other leukocyte counts are under safe boundaries. It is mandatory to follow strict aseptic precautios for all anesthetic and surgical maneuvers. In severe thrombocytopenic patients, platelet transfusion should be considered. Also, it is recommended to establish a good oral hygiene.

The author made a periodontal survey on 2,000 Korean adolescents in Seoul special city and Kyoungki-Do, to detect periodontal conditions and treatment needs. The obtained results were as follows: 1. 1.20% of adolescents had healthy periodontal tissues. 2. 11.95% showed only the gingival bleeding on probing, 66.55% had the calculus. 3. The proportions of adolescents with pocket depths about 4 to 5mm and over 6mm were 19.95% and 0.35% respectively. 4. Periodontal treatment need proportion showed 98.80% in oral hygiene instruction and 86.65% in oral prophylaxis; mean number of sextants affected was 2.96. 5. 0.35% was needed complex periodontal treatment. 6. In the sex and regional distribution, girls were slightly higher than boys in periodontal treatment needs and seoul than Kyoungki-Do; but the difference was not significant statistically.(p<0.05) 7. In the age distribution, periodontal treatment needs did not increase evidently with age; but comparing those for 15 years old with 19, the latter was slightly higher than the former.(p<0.05)

Backgrounds/Aims: Extra hepatic portal venous obstruction (EHPVO) is the most common cause of portal hypertension in Indian children. While endoscopy is the primary modality of management, a subset of patients require surgery. This study aims to report the short- and long-term outcomes of EHPVO patients managed surgically. Methods: All the patients with EHPVO who underwent surgery between August 2007 and December 2021 were retrospectively reviewed. Postoperative complications were classified after Clavien-Dindo. Binary logistic regression in Wald methodology was used to determine the predictive factors responsible for unfavourable outcome. Results: Total of 202 patients with EHPVO were operated. Mean age of patients was 20.30 ± 9.96 years, and duration of illness, 90.05 ± 75.13 months. Most common indication for surgery was portal biliopathy (n = 59, 29.2%), followed by bleeding (n = 50, 24.8%). Total of 166 patients (82.2%) had shunt procedure. Splenectomy with esophagogastric devascularization was the second most common surgery (n = 20, 9.9%). Nine major postoperative complications (Clavien-Dindo > 3) were observed in 8 patients (4.0%), including 1 (0.5%) operative death. After a median follow-up of 56 months (15-156 months), 166 patients (82.2%) had favourable outcome. In multivariate analysis, associated splenic artery aneurysm (p = 0.007), isolated gastric varices (p = 0.004), preoperative endoscopic retrograde cholangiography and stenting (p = 0.015), and shunt occlusion (p < 0.001) were independent predictors of unfavourable long-term outcome. Conclusions: Surgery in EHPVO is safe, affords excellent short- and long-term outcome in patients with symptomatic EHPVO, and may be considered for secondary prophylaxis.
Objective: Currently, rivaroxaban is widely used clinically for thromboprophylaxis after surgery. However, there are concerns on effectiveness and safety of rivaroxaban for its proper use. We aimed to evaluate the effectiveness and safety of rivaroxaban in orthopaedic patients after total hip replacement surgery in a large medical centre after the preferred formulary was switched from enoxaparin to rivaroxaban. Methods: The study was conducted on the patients who underwent hip arthroplasty surgery at the department of Orthopaedic Surgery at Seoul St. Mary's Hospital, South Korea. Electronic medical records were retrospectively reviewed to identify patients treated with rivaroxaban following total hip replacement between February 2011 and March 2012. Evaluation criteria included indications for use, dose, initiation and duration of therapy, drug interactions, adverse reactions, and status of health care reimbursement. The patients who were on enoxaparin were also reviewed as a reference. Results: We identified 57 patients who received rivaroxaban and 50 who received enoxaparin. All patients were prescribed the drugs for Korean Food and Drug Administration-approved indications. No thromboembolic or bleeding events were observed in either group. However, only 5.3% of rivaroxaban- treated patients had an appropriate length of prophylaxis and only 3.5% began rivaroxaban treatment at the recommended time. Surprisingly, 47.4% of rivaroxaban-treated patients received rivaroxaban despite being ineligible for reimbursement benefits. Conclusion: Rivaroxaban was generally well tolerated clinically. However, the duration of treatment, the time of initiation and patient eligibility for reimbursement require improvements, emphasising the need for education which indicates the area of pharmacists' involvement.
Objectives : The purpose of this study was to analyze the influence which the professional dental hygiene education has on the knowledge and behavioral change for oral health to the students in the departments of dental hygiene. Methods : 771 students in the first grade and 646 students in the third grade who were attending the departments of dental hygiene from 12 colleges in Korea were surveyed. The self-administered questionnaires were distributed to the students in the colleges during May and asked them to answer the questions and then recovered them on the spot. The collected questionnaires were analyzed by using a SPSS/PC program and the difference of significance depending on the group of the students was tested by Chi-square test or Fisher's exact probability test. Results : In the number of eating snacks by the students during one day, 2-3 times was the highest, irrespectively of the grade. The rate of the students brushing their teeth after snack was higher in the third-grade students(34.8%) than in the first-grade students(20.8%). As the path of acquiring oral health knowledge, all of the first-grade and third-grade students replied that their school classes had impacted them the most. The rate of toothache experience was a higher tendency in third-grade students compared to the first-grade students(p=0.116). The rate of gingival bleeding experience was lower in the third-grade students than in the first-grade students. The rate of oral prophylaxis experience was higher in the third-grade students than in the first-grade students. In the smoking rate, there was lower in the third-grade students than in the first-grade students. The rate of acknowledging smoking hazard to the periodontal health was higher in the third-grade students than in the first-grade students. Conclusions : This study revealed that the third-grade students of dental hygiene departments who were majoring in dental hygiene had a higher perception of oral health than the first-grade students whose the dental hygiene education period was short.

Between 1988 and 1992, seven patients with overt meningeal leukemia who had received adequate central nervous system (CNS) prophylaxis were treated with intermittent craniospinal irradiation and intrathecal methotrexate (IIIC). Follow-up time ranged from 8 months to 41 months with median of 20 months. Three of 7 patients developed subsequent CNS relapse. CNS remission durations were 8, 9, 13, 20, 28, 34, 36 months from diagnosis of CNS leukemia for which IIIC was given. Disease free survival after CNS relapse ranged from 2 to 36 months with median of 11 months. Overall survival after CNS relapse ranged from 8 to 41 months with median of 28 months. Five patients died of sepsis and bleeding secondary to bone marrow relapse. Two patients are alive at present. But they developed recurrent CNS disease 10 to 11 months after completion of IIIC. To improve the outcome, modification of IIIC by reduction of rest period and prolonged administration of intrathecal chemotherapy after completion of IIIC are required.
