1.Clinical Outcomes of Percutaneous Endoscopic Laser Lumbar Discectomy.
The Korean Journal of Pain 2005;18(1):34-38
BACKGROUND: Over the years, disc surgery has progressively evolved in the direction of decreasing trauma and its invasiveness. Conventional open surgery has many complications, such as scarring, instability, bleeding and a relative high mortality rate. Minimally invasive spinal surgery is now an alternative to a traditional discectomy. Herein, we present an operative technique, and the early results, for a percutaneous endoscopic lumbar discectomy in herniated lumbar disc disease. METHODS: 43 patients, including 27 men and 16 women, with ages ranging from 18 to 66 years, were enrolled in this study. All the patients showed a protruded or extruded soft disc herniation at the lumbar level on magnetic resonance imaging and computed tomography. A percutaneous endoscopic lumbar discectomy was applied to the patients, and clinical responses evaluated using MacNab's criteria. RESULTS: 40 patients were regarded as showing successful responses (93.1%), and there were no severe complications, such as a hematoma, nerve injury, postoperative dysesthesia or death. One patient underwent fusion surgery for remnant back pain six month later. CONCLUSIONS: We conclude that, in properly selected patients, a percutaneous endoscopic lumbar discectomy is a safe, noninvasive and effective treatment modality for herniated lumbar intervertebral disc disease.

We have compared the findings of MRI with those of hip arthroscopy in 22 hips in adults with pilinful hip diseases. From March l995 to March 1997. We performed arthroscopy of the hips in symptomatic 22 patients. Fifteen cases were men and the mean average age was 46 years old. Preoperatively, the patients was diagnoseil with careful physical examinations and MR arthrogram or MR1. Among them, acetahular lahrum tears were 13 cases. synovial lesions were 3 cases and avascular necrosis of femoral head were 6 casee. We have examed cartilage softening, indentation or defect of femoral head and acetabulum, acetabular lahrum, loose hodies and synovial lesion hy arthroscopy. Under the arthroscopic guide, We had resected the torn Jahrum in S cases, removed a loose hodies such as synovial chondromatosis in 1 case and excised a synovial pathology in 2 cases. The others had a open arthrotomy in 8 cases. The sensitivity of MRI was 89.5% and its accuracy was 77.3% compared with arthroscopic findings. Average follow-up lengths was 8.6 months and 17(77.3%) of 22 patients were improved clinically. The arthroscopy of the hip is less invasive and a useful investigation for painful hip diseases for labral tears and synovial lesions in adults cspecially when standard MRI fails to prove a exact hip joint pathology, but it may be useless in avascular necrosis of femoral head. Also it is technical demanding and necessary to long-term follow-up.

Benign tumors of the esophagus occur rarely as compared with the incidence of carcinomas. Among the benign tumors of the esophagus such as leiomyoma, lipoma, hemangioma, papilioma. polyp, cystetc. leiomyoma is the most common, although less than 10 percents of leiomyomas of the gastrointestinal tract are found in the esophagus. Most of leiomyomas of the esophagus present as solitary lesions but multiple tumors occur in about 4 percents of cases. Leiomyomas of the esophagus are diagnosed by thorough clinical evaluation, esophagogram and upper gastrofiberscopic examination but histological confirmation requires surgical or necropsy specimens. Occasionally gastrofiberscopic polypectomized specimens are used. We report one case of multiple leiomyomas of the esophagus located in between 25 cm and 40 cm distance from the incisor in a 38-year-old man who complained of vague substernal discomfort for about 10 years. Gastrofiberscopic polypectomized specimen was used for preoperative histological confirmation. The pathologic examination of the specimen showed leiomyoma of the esophagus.

BACKGROUND: Perioperative noxious stimuli and inflammation may induce peripheral and central sensitization. Together, these changes contribute to the state of postinjury pain hypersensitivity found postoperatively. Preemptive analgesia may prevent nociceptive inputs generated during surgery from sensitizing central neurones and may therefore, reduce postoperative pain. We studied whether or not intravenous meperidine infusion before induction could affect postoperative pain and analgesic consumption when compared with intravenous meperidine infusion at peritoneum closure. METHODS: Female patients scheduled for cesarean section were randomly assigned to one of two groups for prospective study. Group I (n=10) received intravenous meperidine (0.5 mg/kg) 5 minutes before induction of anesthesia and group II (n=10) received the same treatment at peritoneal closure. Both groups had a continuous infusion of meperidine (5 mg/hr) immediately after intravenous bolus meperidine. Postoperative pain relief was provided with intravenous meperidine from a PCA system (Walkmed , Medex, USA). Postoperative visual analogue pain scores (VAS), meperidine consumption and side effects were examined and compared between the groups for two postoperative days. RESULTS: At two hours post surgery VAS at rest were below 3 in both groups and were not statistically significant. VAS on motion were slightly higher than VAS at rest in both groups and were not statistically significant. There was no significant difference in meperidine consumption. There were minor side effects such as nausea, somnolence, dizziness and pruritus, but no patients needed any treatment and all of them were satisfied. CONCLUSION: Preemptive or postincisional intravenous PCA with meperidine was equally effective for postoperative analgesia after cesarean section, with minor side effects. These results suggested that there was no reason for applying preemptive analgesia for cesarean section patients. Further studies will be needed to evaluate preemptive effects of intravenous meperidine or other analgesics in cesarean section patients.

Orthognathic surgery became more popular because people are more interested in facial profile changes and are more receptive to surgery. As people seek beauty as well as function in maxillofacial surgery, patient's aesthetic demand becomes higher. Considering these big changes, one of the major reasons is surgery-first orthognathic approach(SFOA), which removes pre-surgical orthodontic treatment. Pre-surgical orthodontic time has been a great barrier to patients in terms of time and social rehabilitation. By SFOA, patients can get surgery as soon as they make up their mind; Patients from abroad can get surgery and get back to their country; They can go back to their work more easily because their occlusion is more acceptable. Surgery first orthognathic approach is still developing in practice and principle. However, as it is based on patient's need, it will play a greater part in the field of orthognathic surgery. Surgery first orthognathic approach together with aesthetic two jaw surgery are expected to change the paradigm in orthognathic surgery.

The purpose of this study was to identify dietary patterns among children and adolescents in Korea and to examine their associations with obesity and some blood profiles. One day food consumption data measured by 24-hour recalls on 2704 subjects aged 1 to 19 were used from 2001 Korea National Health and Nutrition Survey. The data of blood profiles available in the ages of 10 or older was also used. After categorizing each food consumed into 29 food or food groups, five dietary patterns were derived through a factor analysis and subjects were classified into three major dietary patterns via a cluster analysis using the factor scores. Three dietary patterns were identified as 'traditional diet' (25.6%), 'westernized-fast food' (6.2%), and 'mixed diet' (68.2%). The 'traditional diet' pattern had a higher percentage in boys. Both the 'traditional diet' and the 'westernized-fast food' had higher proportions of adolescents (12-19 y) than younger children, while the 'mixed diet' had a higher percentage of preschool children (1-5 y). Obesity rate analyzed within each age group showed no differences among 3 dietary pattern clusters. Blood pressure and all plasma profiles were not different among dietary patterns when adjusted with age and gender. Conclusively, children and adolescents in Korea had three distinct dietary patterns, which were associated with gender and age. These patterns could be useful to plan nutrition interventions for teenager health promotion.

BACKGROUND: Intention to leave was an important managerial issue among physicians working in public health centers. This study was conducted to explore the relationship between job participations and intention to leave among physicians working in health centers. METHODS: A cross-sectional questionnaire survey was conducted to gather information about job participation, intention to leave and demographics among physicians (n=243) in public health centers in Korea. Job participation was measured by 15 items categorized 3 dimensions. Multiple regression analysis was performed to determine the effect of job participation on intent to leave among physicians working in public health center. RESULTS: Participation of medical treatment and administrative job were significantly associated with intention to leave adjusted for sex, age, income, working area, working duration, tenure, and overall job satisfaction. Therefore, physicians who actively participated in administrative job showed a lower turnover intention. Physicians who actively participated in medical treatment job had a higher quit intention. CONCLUSION: To retain qualified physicians in public health center, education should be reinforced to physician for administrative capacity building.

BACKGROUND: It is difficult to manage intractable pain from advanced carcinoma of the upper abdomen. One method used to control pain associated with these malignancies is to block the splanchnic nerve. We investigated that VAS (visual analogue scale) difference before and after splanchnic nerve block (SNB) and pain relief day. Also we studied relationship between VAS before SNB and pain relief day. METHODS: A rewiew of 70 patients who took splanchnic nerve block (SNB) from September 1994 to February 1998 was carried out to assess age, sex, primary diseases, pain sites, VAS before and after SNB, date of diagnosis, date of SNB, date of death and pain relief day, etc. RESULTS: Of 70 patients, 44 were males and the remaining 26 were females. The causes of pain were stomach cancer 28 (40%), pancreatic cancer 18 (25%), gall bladder cancer 7 (10%), hepatoma 6 (8.6%) respcectively. Average day from diagnosis to SNB was 272 and average day from diagnosis to death was 341. So, patients died on the average 69 days after they took the splanchnic nerve block in pain clinic. VAS average before SNB was 8.01 and VAS average after SNB was 3.64. Patients felt pain relief during 35 days after SNB. Pain relief day of patients who had lower VAS before SNB was longer than that of patients who had higher VAS before SNB. CONCLUSION: Early application of splanchnic nerve block will make the patients endure the cancer pain more easily.

BACKGROUND: Infracochlear approach indroduced by Ghorayeb et al. in 1988, was performed to reach the petrous apex with the canal wall-down procedure. Giddings et al. described the transcanal infracochlear approach preserving the posterior wall of the external auditory canal for treatment of the cholesterol granuloma in the petrous apex in 1991. OBJECTIVES: Surgical anatomy for the infracochlear approach to the petrous apex was reviewed in order to understand clinical applicability of this approach. MATERIALS AND METHODS: This study was performed using 20 human cadaveric temporal bones by the microscopic dissection. Measurements were obtained between different structures to find reliable angles and distances to guide working in the petrous apex region. RESULTS: The petrous apex was entered through the fenestra between the cochlea, carotid, and jugular bulb. The mean area of the fenestrae was 11.7+/-5.5mm2. The distance from the vertical segment of the facial nerve to the petrous apex was 25.3+/-2.4mm. The angle of the approach to the petrous apex was 37.3+/-5.1degrees to the axis of the internal auditory canal. CONCLUSION: The infracochlear approach could be used to obtain the route for a drainage procedure or a biopsy at the petrous apex without damaging hearing organs and major vessels. The canal-down procedure was needed to assess the petrous apex successfully.
