The ankle is an important joint supporting the entire musculoskeletal system during standing and walking. Current opinion has emphasized necessity of anatomical reduction and rigid internal fixation for a displaced or unstable fracture of the ankle. The purpose of this study was to evaluate the correlation of the adequate surgical operative methods and postoperative care with prognosis. The authors analysed 104 cases of ankle fracture, treated operatively in Department of Orthopedic Surgery of Dae-Han Hospital from January 1991 to December 1994, followed up more than one year. The results were as follows: 1. According to the classification of Lauge-Hansen and Danis-Weber, the most common type was supination-external rotation and type B, respectively. 2. The most common cause of injury was slip down and the others were traffic accident, fall down and direct trauma. 3. According to the criteria of Meyer, the result of treatment was good or excellent in 94 cases (90.4%) radiologically and in 91 cases (87.5%) clinically. 4. The complications were 5 cases of traumatic arthritis, 3 cases of malunion, 2 cases of non-union and 1 case of infection. 5. The early ROM exercise after accurate reduction and rigid internal fixation was very important in treatment of fracture of the ankle.

Recently, the incidence of fracture and dislocation of the proximal humerus has been increased with increment of traffic accident and industrial accident. Although most proximal humeral fractures can be treated satisfactorily by simple conservative treatment, the displaced fracture or fracture-dislocatiion of the proximal humerus demands special treatment and judgement. It has been reported that the results of the surgical treatment of the unstable fracture of the proximal humerus was better than that of conservative treatment. The authors analysed 32 cases displaced fracture or fracture-dislocation of the proximal humerus treated operatively which were followed up more than 1 year at the Dae Han Hospital from June, 1990 to May, 1993. The obtained results were as follows; l. According to Neer's classification, there were 2-part fracture in 3 cases(9%), 3-part in 17 cases(54%), 4-part in 2 cases(6%), fracture-dislocation in 8 cases(25%) and head splitting in 2 cases(6%). 2. The clinical results by Neer's criteria were excellent in 9 cases(28%), good in 14 cases(44%), fair in 7 cases(22%), and poor in 2 cases(6%) among the 32 cases. 3. The complication were limitation of motion in 4 cases, avscular necrosis of humeral head in 2 cases, nonunion in 1 case, delayed union in 1 case, ectopic ossification in 1 case and malunion in 1 case. 4. In the unstable fracture of the proximal humerus treated by accurate reduction and rigid fixation with intensive rehabilitation can be obtained, relatively satisfactory results because of the inability to maintain an acceptable closed reduction.

Cryopreservation is able to store the surplus pre-embryos for freezing and furthermore thawing and transfer in a subsequent cycle. Cryopreserving cells which are maintaining their viability are the very complex process. This study has been carried out in order to find the effects of cryopreservation steps, freezing media and embryonic stages on the rates of viability and development of cryopreserved mouse embryos. Female ICR mice (6~8 weeks old) were induced to superovulate by sequential intraperitoneal injection of 5 IU PMSG and 5 IU hGC 48h apart. Mouse embryos were collected according to its developmental stage after the injection of hCG. Embryos were cryopreserved not only by cryoprotectant step (1 step~ 4 step) but also in a variety of media (HTF, IVF medium, D-PBS) and cell stage. The results were as follows: There is no clear advantage in these freezing media of rapid method, but 4 cell and 8 cell of slow method (2, 3, 4 step) have advantage in D-PBS. The development of embryos according to cell stage become greater in 8 cell stage. In the treatment steps of cryopreservation, the development of embryo to blastocyst was similar among rapid method, but the development of 4 cell and 8 cell embryos to blastocyst according to slow method was better than rapid method.

OBJECTIVES: To investigate longitudinal changes in behavior and quality-of-life (QoL) in children with sleep disordered breathing (SDB) after adenotonsillectomy (AT). METHODS: This study prospectively enrolled 148 children who underwent AT for SDB. Caregivers filled out Korean attention deficit hyperactivity disorder (ADHD) rating scale (K-ARS) and Korean version of the obstructive sleep apnea-18 (KOSA-18) at preoperative 1 day, postoperative 1 month, and postoperative 6 months. Longitudinal changes in K-ARS and KOSA-18 were evaluated and compared among subgroups. RESULTS: Both K-ARS and KOSA-18 scores improved immediately at postoperative 1 month and were maintained at postoperative 6 months. The mean preoperative K-ARS scores of the non-ADHD, ADHD-trait, and overt-ADHD groups showed uniformly immediate and sustained improvements. Also, the mean preoperative KOSA-18 scores of the small, moderate, and large impact groups were significantly improved both at postoperative 1 month and 6 months. The changes in behavior and QoL showed no significant differences with regard to the aforementioned factors. CONCLUSION: After AT, we may expect immediate and sustained improvements in behavior and QoL in children with SDB regardless of preoperative symptom severity. Moreover, by performing AT, improvements in behavior and QoL are expected regardless of sex, age, allergic trait, or concurrent coblation-assisted turbinoplasty. These findings may help our colleague physicians counselling pediatric SDB patients and their caregivers.

Dermatomyostis is an idiopathic inflammatory myopathy characterized by progressive symmetric proximal muscle weakness and typical cutaneous lesions. The association of adult dermatomyositis and malignancy in particular has generated much attention recently. A 66 year-old male biopsy proven dermatomyositis had bloody hemoptysis 1 week ago and skin manifestation aggravated during steroid therapy in outpatients rheumatology clinic. During routine evaluation mediastinal mass was found, and following bronchoscopic biopsy confirmed small cell lung carcinoma. In Korea a few cases were reported about stomach cancer, breast cancer and acute lymphoblastic leukemia but small cell lung cancer was not reported yet. So we reported a case of small cell lung cancer developed in patients with dermatomyosits during therapy with brief review of literatures.

PURPOSE: The classic technique for open reduction of subcondylar fractures is the submandibular approach. The aim of this study was to evaluate clinical result of retromandibular approach to displaced subcondylar fractures. MATERIAL AND METHODS: During a period of 24months we perfomed a prospective study with a retromandibular approach in 23 paients with displaced subcondylar fractures. In this article we describe clinical result in 23 patients with follow ups for 3 months after surgery. Preoperatively all patients had malocclusion and radiology demonstrated displacement. RESULT: The retromandibularl approach for ORIF was good in all case. Mouth opening(M/O) was 49mm. Occlusion was good too. Permanent facial nerve palsy was not detected. CONCLUSION: Our findings indicate that the retromandibular approach is a safe technique for subcondylar fractures.

BACKGROUND: It was reported that patients who have left ventricular hypertrophy have higher D allele frequency of angiotensin I-converting enzyme gene polymorphism, especially in Caucasian normotensive men. We studied to know whether genetic polymorphism of angiotensin I-converting enzyme gene is associated with the development of left ventricular hypertrophy in Korean people whose genotype frequency is quite different from that of Caucasians. METHODS: Total 156 patients were included in this study. Presence of hypertension was checked with the criteria that hypertensives are one whose blood pressures were all above 140/90 at least 3 times spanning 2 months or one who had been diagnosed as hypertension and on his medication. Left ventricular mass index(LVMI) was calculated using electrocardiogram by Rautaharju equation, and left ventricular hypertrophy(LVH) was defined as LVMI was above 131g/m2 in male or above 110g/m2 in female. Genomic DNA was extracted from the mononuclear cell of each subjects and PCR was performed using new primers for the region of intron 16 and exon 17. RESULTS: Genotype frequencies of D/D genotype and D allele were 0.200 and 0.413 respectively in group with LVH(n=40), 0.103 and 0.392 respectively in group without LVH(n=116). There was no significant difference with each other group. However, when only the normotensives were included in this analysis, frequency of D/D genotype is significantly higher in group with LVH(0.231, n=26) than in group without LVH(0.076, n=79)(Fisher's exact test,p<0.05). There was no significant difference in genotype frequency between the normotensives(n=105) and the hypertensives(n=51). CONCLUSIONS: In Korean people, D allele of polymorphism of angiotensin I-converting enzyme gene is also associated with development of left ventricular hypertrophy in the normotensives and is not associated with essential hypertension.

PURPOSE: The cisplatin and etoposide had been reported to be an effective anti-tumor drug for small cell lung cancer, ovarian cancer, breast cancer and so on. The aim of this study was to evaluate the stability of cisplatin and etoposide in aqueous solution. MATERIALS AND METHODS: Cisplatin 200 microgram/ml was prepared in 0.9% sodium chloride and stored in either glass bottle or polyvinyl chloride (pvc) bag and protected from light or exposed to fluorescent light. Etoposide solution was prepared in 0.9% sodium chloride, and contained in glass bottle. Precipitating concentration was achieved using 200 microgram/ml, 400microgram/ml, 600 microgram/ml, and 1000 microgram/ml of etoposide solution. Samples were stored at room temperature and visually inspected and assayed for etoposide and cisplatin content by high-performance liquid chromatography after 15 minutes, 2, 4, 8, 12, 16 and 24 hours of storage. RESULT: 1) Cisplatin concentration decreased less than 10% from initial concentration for 24 hours of storage, both in glass bottle and pvc bag. Stability of cisplatin 200 microgram/ml in both container were not different. and Condition of light exposure did not have significant effect on stability of cisplatin 200 microgram/ml in glass bottle. 2) The etoposide 200 microgram/ml was not precipitated and stable for 24 hours, but we could find the precipitates of etoposide with the concentration of 400 microgram/ml or higher for 24 hours. CONCLUSION: Cisplatin 200 microgram/ml and etoposide 200 microgram/ml in 0.9% sodium chloride were stable at room temperature under room fluorescent light for 24 hours.
