BACKGROUND: In previous our retrospective study, we concluded that administered fluid volume, duration of operation, operative procedures and anesthetic techniques were the major factors of postoperative urinary retention. However, the administered fluid volume, age, types and duration of the operation confined to hemorrhoidectomy was questioned as a precipitating factor. The high retention rate in spinal anesthesia is also questioned. METHODS: We investigated these possible precipitating factors of urinary retention in healthy patients (n=154) undergoing hemorrhoidectomy. The patients were randomly divided into three different anesthetic techniques: caudal (2% lidocaine 300 mg with 1 : 200,000 epinephrine), spinal (0.5% tetracaine 5 mg with epinephrine 0.1 mg or 5% lidocaine 40 mg) and general (enflurane, N2O, vecuronium). Urinary retentin was searched according to above factors following surgery. RESULTS: The overall urinary retention rate was 46.1%. The retention rate in patients with spinal anesthesia was higher than that in those with other anesthetic techniques (p<0.05). There was no significant difference between patients with lidocaine and tetracaine spinal anesthesia in urinary retention rate. The administered fluid volume in patients with urinary retention was significantly higher than that of patients without retention (p<0.05). Age, duration and types of hemorrhoidectomy did not significantly affect urinary retention rate. CONCLUSIONS: Restriction of fluid administration and avoidance of spinal anesthesia are necessary in reducing postoperative urinary retention following hemorrhoidectomy.

PURPOSE: The purpose of this study was to evaluate the clinical results of fixation of the unstable osteochondral dissecans (OCD) lesion with autologous osteochondral plugs. MATERIALS AND METHODS: This study was conducted in 19 patients who were relevant to the International Cartilage Repair Society 2, 3, or 4 who were treated with autologous osteochondral plugs and followed-up for more than 2 years from January 2004 to January 2012. Clinical evaluation was performed by comparing the preoperative and last follow-up scores of Lysholm score and subjective International Knee Documentation Committee (IKDC) score. RESULTS: All patients were male and the average age was 19.1 years. Of the 19 cases, there were 16 cases of medial femoral condyle lateral side lesion, 2 cases of lateral femoral condyle articular surface, and 1 case of femoral intercondylar notch lesions. The average size of the lesion was 5.68 mm2, and average use of osteochodral plugs were 4.3. Average follow-up period was 38 months. Preoperative Lysholm score, IKDC subjective score showed significant improvement. CONCLUSION: Fixation with autologous osteochondral plugs for unstable OCD uses the remnant tissues therefore conserving it, which is thought to be the positive aspect of this type of operation.

There is no current guideline for percutaneous coronary angioplasty in stenotic ectatic coronary arteries because of the heterogeneity of the coronary artery morphology. We report two successful angioplasty cases in coronary artery ectasia with different clinical scenarios. One case showed atherosclerotic stenosis in the ectatic portion of the right coronary artery that was aggravated after a coronary artery bypass graft. In this case, balloon angioplasty alone without stenting showed acceptable results at the 6-month follow-up coronary angiography. In the other case, we used a peripheral artery balloon and stent for stenosis in the ectatic portion of a large coronary artery. Six-month follow-up coronary angiography showed excellent patency of the previously implanted peripheral stent.

BACKGROUND/AIMS: Retreatment after initial treatment failure for Helicobacter pylori is very challenging. The purpose of this study was to evaluate the efficacies of moxifloxacin-containing triple and bismuth-containing quadruple therapy. METHODS: A total of 151 patients, who failed initial H. pylori treatment, were included in this retrospective cohort study. The initial regimens were standard triple, sequential, or concomitant therapy, and the efficacies of the two following second-line treatments were evaluated: 7-day moxifloxacin-containing triple therapy (rabeprazole 20 mg twice a day, amoxicillin 1,000 mg twice a day, and moxifloxacin 400 mg once daily) and 7-day bismuth-containing quadruple therapy (rabeprazole 20 mg twice a day, tetracycline 500 mg 4 times a day, metronidazole 500 mg 3 times a day, and tripotassium dicitrate bismuthate 300 mg 4 times a day). RESULTS: The overall eradication rates after moxifloxacin-containing triple therapy and bismuth-containing quadruple therapy were 69/110 (62.7%) and 32/41 (78%), respectively. Comparison of the two regimens was performed in the patients who failed standard triple therapy, and the results revealed eradication rates of 14/28 (50%) and 32/41 (78%), respectively (p=0.015). The frequency of noncompliance was not different between the two groups, and there were fewer adverse effects in the moxifloxacin-containing triple therapy group (2.8% vs 7.3%, p=0.204 and 25.7% vs 43.9%, p=0.031, respectively). CONCLUSIONS: Moxifloxacin-containing triple therapy, a recommended second-line treatment for initial concomitant or sequential therapy failure, had insufficient efficacy.

BACKGROUND: A Stellate ganglion block (SGB) is a sympathetic nerve block method which has been used most frequently in pain clinics due to its wide range of indications. However, SGB leads to regional sympathetic denervation of the heart and to changes in the hemodynamics. The aim of this study was to compare hemodynamic effects as well as echocardiographic changes after a left SGB (LSGB). METHODS: Fourteen healthy male volunteers were studied. The LSGB was performed with 1% mepicacaine 6 ml. Arterial blood pressure, electrocardiographic and echocardiographic variables were measured before the LSGB, 15 and 30 minutes after the LSGB. RESULTS: Arterial blood pressure, ejection fraction and transmitral inflow velocity variables showed no significant changes compared to pre-LSGB values. P-P interval increased significantly 15 minutes after the LSGB, and the Q-T interval increased significantly 30 minutes after the LSGB. The diastolic pulmonary venous flow velocity decreased significantly 15 minutes after the LSGB. CONCLUSIONS: These results showed that a LSGB decreased the heart rate without detrimental changes of left ventricular relaxation in healthy male volunteers.

Reversible focal lesions on the splenium of the corpus callosum (SCC) have been reported in patients with mild encephalitis/encephalopathy caused by various infectious agents, such as influenza, mumps, adenovirus, Varicella zoster, Escherichia coli, Legionella pneumophila, and Staphylococcus aureus. We report a case of a reversible SCC lesion causing reversible encephalopathy in nonfulminant hepatitis A. A 30-year-old healthy male with dysarthria and fever was admitted to our hospital. After admission his mental status became confused, and so we performed electroencephalography (EEG) and magnetic resonance imaging (MRI) of the brain, which revealed an intensified signal on diffusion-weighted imaging (DWI) at the SCC. His mental status improved 5 days after admission, and the SCC lesion had completely disappeared 15 days after admission.

Heterotopic bone formation in the gastrointestinal tract is a rare phenomenon. Most reported cases were associated with benign and malignant neoplasms, except for a case in which heterotopic bone formation was found in a patient with Barrett's esophagus. The exact pathogenesis of the disease has not yet been established. However, most heterotopic bones found in the gastrointestinal tract were associated with mucinproducing tumors of the appendix, colon, and rectum. Inflammation may also play a role in osseous metaplasia in a case with bone formation at the base of an ulcer in Barrett's esophagus. Here, we report on a patient with heterotopic bone formation in normal gastric cardiac mucosa. A 50-year-old female visited our hospital for a routine health examination. She had no gastrointestinal symptoms, and her physical examination, blood test, X-ray, urine, and stool examination results were normal. A 0.3 cm sized polypoid lesion located just below the squamocolumnar junction was observed on upper gastrointestinal endoscopy. A piece of biopsy was taken. Histologically, a lamella bone trabecula and chronic inflammatory cells were observed in the gastric cardiac mucosa. The follow-up endoscopy performed one month later showed no residual lesion.

PURPOSE: The Korean Intern Resident Association and Korean Society of Emergency Medicine announced the 'Hospital violence response system' to secure patient safety and provide a health care provider countermeasures against hospital violence. The aim of this study is to investigate the response to hospital violence in the ER and which measures could improve the current status. METHODS: Emergency medicine residents in the Seoul, Incheon, Kyung-gi area participated in the survey. The questionnaire included 4 categories (1. Awareness of protocol, 2. Experience and countermeasure for hospital violence, 3. Understanding of protocol, 4. Suggestions to improve against hospital violence) RESULTS: Among 362 candidates, 236 (65.2%) participated in the survey. Only 7.6% of residents have not experienced hospital violence. In the group of people who were aware of the protocol, participants tended to be more familiar with processes of the hospital violence response protocol, and willing to deal with violence using a better systematic support. People did not counteract to hospital violence because the process was thought to be too complicated. Only 63 participants were actively involved in an official course for countermeasure. Participants suggested that police should deal more appropriately with hospital violence. CONCLUSION: The hospital violence response protocol is thought to have a positive effect on appropriate management of hospital violence. However, a multi-disciplinary approach to hospital violence from the hospital, police, and judicial authority should be developed.
