OBJECTIVE: The aim of this study were to compare the effects of EG and PROH on cryopreservation of mouse and human embryos, and to find the optimal protocol for embryo freezing. METHODS: Human embryos derived from fertilized eggs showing 3 pronuclei (PN) and mouse embryos were divided into two groups respectively: dehydrated with 1.5 M EG+0.2 M sucrose or 1.5 M PROH+0.2 M sucrose using the slow freezing method. Moreover mouse embryos were controlled the exposure time of cryoprotectant during dehydration or rehydration steps. RESULTS: The survival rates of human embryos were 79.2% (84/106) in EG group and 77.9% (88/113) in PROH group. In mouse embryos, the survival and development rates up to blastocyst were 70.6% (245/347), 44.1% (123/279) in EG group and 62.1% (198/319), 45.1% (123/279) in PROH group, respectively. However, in EG group, partially damaged embryos after thawing were decreased compared to PROH group. In combination group, when the exposure time during dehydration and rehydration were reduced, the survival and embryonic developments were increased slightly, but not significant. CONCLUSION: Cryopreservation of mouse and human embryos at cleavage stage by using EG or PROH exhibited no statistical difference in the survival rate and/or developmental rate to blastocyst. However, the use of EG for cryopreservation of embryos might reduce the exposure time of the cryoprotectant because of a high permeation of EG and result in lessen its toxic effects.

OBJECTIVES: The objective of this study is to investigate differences of clinical characteristics between a healthy female control group and female panic disorder (PD) patients with early sexual abuse history (PD+S) and without early sexual abuse history (PD-S). METHODS: We examined data from 83 patients diagnosed with PD and 20 healthy control subjects. We divided the patients with PD into PD+S (32 patients) and PD-S (51 patients) to compare demographic and clinical characteristics. The following instruments were applied: the Stress coping strategies, the Beck Depression Inventory (BDI) , the Panic Disorder Severity Scale, the Anxiety Sensitivity Index-Revised (ASI-R), the Albany Panic and Phobia Questionnaire (APPQ) and the NEO-neuroticism. RESULTS: Compared to the PD-S, the PD+S group showed higher scores in neuroticism and the APPQ. And, in the PD+S group, the scores of neuroticism were correlated with the ASI-R and APPQ subscale scores and the APPQ total scores were associated with the scores of BDI. CONCLUSIONS: This study shows that female PD+S patients have higher scores in neuroticism and the APPQ than the PD-S group, and these factors are associated with the panic-related symptoms severity. It emphasizes the need of specific strategies considering the childhood abuse history such as early sexual abuse in clinical approach among patients with PD.

Mycoplasma pneumoniae is the most common etiologic agent of pneumonia in school-aged children and young adults. It involves not only the respiratory system but includes extrapulmonary complications such as exanthem, hemolysis, arthritis, hepatic dysfuction, cardiac disease, and central nervous system disease. The pathogenesis of extrapulmonary involvements may be an autoimmune phenomena. Recent studies suggest that bronchial asthma can be initiated by Mycoplasma pneumoniae infection. We experienced a five-year-old girl suffering simultaneously from Guillain-Barr syndrome and initial bronchial asthmatic attack after mycoplasma pneumonia. She was admitted with lower-leg pain and weakness for three days. Ten days before admission, she was coughing and showed on a chest X-ray, pneumonic infitrations of both subhilar peribronchial areas. The titers of anti-mycoplasma antibody and cold hemagglutinin were 1:80 and 1:32, respectively. With a progression of paralysis to the upper extremities, she showed dyspnea, dysphagia and right facial palsy on the second hospital day. We performed a tracheostomy and started artificial ventilation. Unexpectedly, she showed continuous dyspnea, poor lung aeration and revealed severe hypoxemia in serial arterial gas analysis. Intravenous theophylline, high-dose corticosteroid and intravenous immunoglobulin therapy resulted in a progressive improvement of lung condition. She recovered completely from neurologic and pulmonic complications after five weeks.

PURPOSE: To identify the risk factors for coronary sequelae in Kawasaki disease, we analyzed and compared the clinical features and laboratory findings of Kawasaki disease in patients younger than one year of age with those over one year of age. METHODS: A retrospective chart review was conducted of all children with Kawasaki disease who were admitted to the Catholic University Taejon St. Mary's hospital between March 1992 and December 1997. RESULTS: Of 162 patients with Kawasaki disease, 36 patients(22.2%) were less than one year of age and four(11.1%) of them had coronary artery aneurysms. On the other hand, 126 patients (77.8%) were above 12 months and 15(11.9%) of them developed coronary artery aneurysms. The Kawasaki criteria signs were not significantly prominent(P<0.05) and maximal platelet count was higher in the infant group(P<0.05) but other clinical and laboratory findings were not different between the two groups. Comparative studies revealed that maximal platelet count was higher (P<0.05), and total duration of fever was significantly longer in the patients with coronary aneurysms(19 cases, P<0.001) than those without coronary aneurysms(143 cases). CONCLUSION: We cannot find any significant clinical and laboratory differences including coronary artery involvement in Kawasaki disease between less than one year of age and over one year. The age of onset seems not to be a predictor for the risk of coronary aneurysm. The principal signs of Kawasaki disease can be less prominent in infant. For this reason, early diagnosis utilizing laboratory findings are important, especially in the course of illness with prolonged fever.

Journal of Korean Foot and Ankle Society 2004;8(2):149-152
PURPOSE: We assessed the clinical results of modified Brostrom procedure as a revision method after failure of a primary reconstruction. MATERIALS AND METHODS: This is a retrospective study of seven patients treated with Modified Brostrom procedure after failed lateral ankle ligament reconstruction between 1996 and 2002. Instability symptom developed average 4.7 month after the initial reconstruction surgery at other clinics. All patients had significant functional impairment before surgery and not responded to conservative protocols. Modified Brostrom procedure was applied to all patients. RESULTS: The average follow up was 51 months (18 to 84). Seven of eight patients had clinical stability following revision reconstruction, six patients (75%) returned to their previous functional level. American Orthopaedic Foot and Ankle Society ankle-hindfoot scores averaged 87.5. There is no difference in active or passive range of motion of plantar flexion or dorsiflexion when compared to the contralateral ankle. However, three patients were noted to have lost some degree of inversion when compated to contralateral ankle. Two patients had osteochondral lesion and multiple spurs and had pain around the ankle that prevented their full recovery. One patient complained of persistent pain which was considered complex regional pain syndrome. CONCLUSION: Though the outcome of the Modified Brostrom procedure as a method of revision surgery was less satisfactory compared to the results of primary ankle reconstruction, it would be an appropriate option when concomitant abnormalities were not accompanying.

Journal of Korean Foot and Ankle Society 2004;8(2):138-141
PURPOSE: The purpose of this study was to document the results of fixation with ethibond suture in akin osteotomy and its advantages. MATERIALS AND METHODS: From May 2001 to January 2004, Akin osteotomy was performed in 218 patients. We reviewed 110 patients (114 feet) who were possible radiographic evaluation more than 6 months after operation. 110 feet had hallux valgus and 4 feet had hallux valgus interphalangeus. 105 patients were female and 5 were male. The average age was 43.8 years old (18 to 68 years old). The average follow up was 9 months (6 to 23 months). After performing the Akin osteotomy at 7 mm from the proximal articular surface of the proximal phalanx, one hole is made on either side of the osteotomy site with a K-wire. The passer was passed through the both holes and the ethibond was passed. And then, the ethibond was tied tightly. 2 sutures in 66 feet and 1 suture in 48 feet were made. Radiographic bone union at 6 months follow up was regarded as success and loss of the reduction, nonunion was regarded as failed. RESULTS: In the radiographic evaluation, bony union were made at 6 months follow up in all feet. There was no difference between 2 sutures and 1 suture, and the knots were removed in 3 feet because of skin irritation. CONCLUSION: The fixation of the osteotomy site using suture material was an effective method in Akin osteotomy. The advantage of this procedure was unnecessity of the material removal.

PURPOSE: To evaluate the clinical and radiographical results of triple osteotomy as a treatment for adult hallux valgus with highly increased distal metatarsal articular ankle (DMAA). MATERIALS AND METHODS: From October 2003 to April 2005, we retrospectively reviewed 7 hallux valgus patients (3 cases: moderate, 4 cases: severe) treated with triple osteotomy and followed-up for more than 1 year after operation. The mean follow up was 15.1 months. The hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA) and the length of 1:2 metatarsal bone were measured. Proximal chevron osteotomy and distal biplanar chevron osteotomy were done in 1st metatarsal bone. Akin osteotomy was added to the base of the proximal phalanx. The clinical result was assessed using the AOFAS Hallux score, tenderness on the medial eminence, ROM of 1st metatarsophalangeal joint, calluses and patient satisfaction. RESULTS: The mean HVA and IMA was improved from 37.5 degrees and 13.4 degrees to 10.5 degrees and 6.2 degrees respectively. The mean DMAA was corrected from 34.2 degrees to 11.2 degrees and mean shortening of 1st metatarsal was 2.4 mm (0.9-5.8 mm). The mean AOFAS hallux score was improved from 66.4 to 92.5 and VAS score (pain on the medial eminence) from 4.3 points to 0.4 points. Metatarsalgia disappeared in all cases and there was no complications such as necrosis of the metatarsal head. CONCLUSION: Triple osteotomy for adult hallux valgus with a highly increased DMAA is effective and should be considered as a part of the treatment armamentarium.

PURPOSE: The purpose of this study is to find out the normal distal tibial articular surface angle in coronal plane in Koreans. This would be helpful as the basic data for ankle reconstruction after trauma or deformity correction. MATERIALS AND METHODS: Weight bearing anteroposterior radiographs of 123 normal ankles were reviewed. A line parallel to the shaft of the tibia was made. Another line was drawn parallel to the articular surface of the distal tibia. The superolateral angle that subtended by these two lines was measured. RESULTS: There were 72 males and 51 females. The mean age overall was 35.7 years old. The mean age for males was 31.9 (28~36) years old. The mean age for females was 41.1 (37~45) years old. The mean distal tibial articular surface angle was 90.8 degrees. The mean distal tibial articular surface angle for males was 91.5 degrees and for females 89.9 degrees. CONCLUSION: The mean distal tibial articular surface angle in coronal plane for Koreans is 90.8 degrees. We can avoid the error of the varization at the ankle alignment when the correction was performed vertical or minimal valgus to tibia tuberosity axis in Korean people.
