Displaced intra-articular fractures of the calcaneus result in serious and prolonged disability. These injuries continue to pose a therapeutic challange and there remains a great deal of controversy regarding treatment, operative versus nonperative. The lateral approach for open reduction, popularized by Palmer, has been used by many authors, with high percentage of excellent results. We treated 21 displaced intra-articular fractures of the calvaneus in 18 patients by open reduction and internal fixation through the lateral approach from July 1990 to May 1992 and the patients have been followed from 12 to 36 months from the time of their injury. The clinical and radiographic analyses were as follows; 1. The most common cause of injury was falls from a height: 19 fractures in 16 patients(88.8%), Spine fracture was most commonly associated injury : 5 patients (27.8%). 2. Fracture was classified according to classification of Paley and Hall. Eight fractures were tongue type(no comminution 4, with comminution 4), 12 joint depression type(no comminution 8, with comminution 4), and a comminuted type. 3. The average bohler tuber-joint angle was

In cases of L4-5 spinal fusions, L5-S1 segment used to be included in the fusion traditionally for fear of progressive deterioration of the lumbosacral motion segment after fusion above. The purpose of this study was to evaluate the advisability of extension to L5-S1 segment in cases of L4-5 fusion for an isolated pathologic condition in L4-5 sement. A retrospective review of 72 patients with spinal fusion for an isolated pathologic condition in L4-5 segment was undertaken to compare the clinical results and adverse effects in two groups. One group consisted of 39 patients with floating L4-5 fusion(SF), and the other group consisted of 33 patients with L4-S1 fusion(LSF). The age, pathologic condition at L4-5, and the fusion method(lateral fusion) were matched in two groups. The mean follow-up period was 43.6 months(ranging 24-69 months). Comparisons were made for operative problems, post-operative complications, the amount of changes in angular motion at the adjacent segments to fusion at the last follow-up compared to the pre-operative motion, and the clinical results of treatment. The LSF group took 38 more minutes and lost 245 grams of more blood in averages to complete the additional surgical procedures compared with those in SF group. Several considerable post-operative complications were one deep infection in SF group and three metal failures of sacral fixation with subsequent two fusion failures in LSF group which were mostly concerned with the sacral fixations. The changes of angular motion at follow up compared to pre-operative motion in SF group were 1.5° gain in average (ranging 3° loss-6° gain) in L3-4 segment and 0.6° gain in average (ranging 5° loss-5° gain) in the L5-S1 segment. Those in L3-4 segment of LSF were 2.8° gain in average (ranging 2°-loss 9° gain). Therefore the higher stress and subsequent degeneration are more likely expected above the L4-S1 fusion rather than below the L4-5 fusion. The satisfactory clinical results were 89.7% in SF group and 87.9% in LSF group without significant difference between two groups. In conclusion there is no need to include the L5-S1 segment in the L4-5 fusion when the pathology is limited to L4-5 segment.

The purpose of this study is to examine the change of enzymeimmuno-assay for prostaglandinE2 in the synovial fluid lavage specimen of patients with mandibular fracture patients without condylar fracture. For this study, fourteen patients (eight males, six females) with mandibular fractures without condylar fracture was investigated to analyse the synovial fluid from upper temporomandibular joint cavities. Synovial fluid was collected from TMJ cavities of mandibular fracture patients before open reduction and after one week of open reduction, and then stored in liquid nitrogen tank after centrifuge. Two synovial fluid lavage samples of TMJs of 2 asymptomatic served as normal controls referred from other data. The concentrations of PGE2 were measured by use of PGE2 EIA system (Amersham). The following results were obtained: 1) In nine patients, the concentrations of PGE2 are lower after open reduction than before. 2) In three patients, the concentrations of PGE2 are higher after open reduction than before. 3) There was no statistical significant between the preoperative group and postoperative 7 days (p>0.05), but there was some difference between the two groups. In conclusion, the results suggest that PGE2 probably does not play as important role in the harm of TMJ.

Digoxin is commonly used in treatment of various heart conditions, such as atrial fibrillation, atrial flutter, and sometimes heart failure. The therapeutic range of digoxin is narrow. Therefore, Digoxin toxicity is common. However, severe digoxin intoxication is uncommon. Many cases involving application of Digoxin immune Fab for digoxin intoxication in other countries have been reported. However, no cases have been reported in Korea. We reported on one case, a 34-year-old male with acute and severe digoxin intoxication who was treated with digibind(R). His chief complaint was gastrointestinal symptoms, including nausea and vomiting. Electrocardiography (ECG) showed third degree atrioventricular (AV) block. After an infusion of digibind(R), third degree AV block rhythm was changed to first degree AV block. Nowadays, we can obtain a digoxin antidote from the national poisoning information center. Therefore, we should actively consider application of Digoxin immune Fab in patients with severe digoxin intoxication.

Carbon monoxide (CO) poisoning is the most common cause of fatal poisoning in the United States and may be the most common worldwide cause of fatal poisoning. CO poisoning can affect the entire body and usually causes neurologic or cardiac injury. While not common, rhabdomyolysis, skeletal muscle necrosis, and renal failure can also occur. We report on a suicidal 22-year-old man who inhaled CO gas from a burning briquette. His case was complicated by compartment syndrome (CS). Finally, he had to undergo fasciotomy and removal of necrotic muscle. A CO poisoned patient who is unconscious cannot describe symptoms and moderate swelling or tenderness might be neglected. Though CS rarely appears in CO poisoning, delayed diagnosis may result in fatal consequences. Therefore, in the case of an unconscious patient, the entire body must be examined closely to identify early signs related to CS (tenderness, swelling, redness). If the diagnosis is uncertain after the clinical evaluation, the pressure within the compartment should be measured.

BACKGROUND: The aim of this study was to determine the prognostic value and optimal sampling time of serum S-100B protein for the prediction of poor neurological outcomes in post-cardiac arrest (CA) patients treated with therapeutic hypothermia (TH). METHODS: We prospectively measured serum S100 calcium binding protein beta subunit (S-100B protein) levels 12 times (0-96 hours) after the return of spontaneous circulation (ROSC). The patients were classified into two groups based on cerebral performance category (CPC): the good neurological outcome group (CPC 1-2 at 6 months) and the poor neurological outcome group (CPC 3-5). We compared serial changes and serum S-100B protein levels at each time point between the two groups and performed receiver operating characteristic curve analysis for the prediction of poor neurological outcomes. RESULTS: A total of 40 patients were enrolled in the study. S-100B protein levels peaked at ROSC (0 hour), decreased rapidly to 6 hours and maintained a similar level thereafter. Serum S-100B protein levels in the poor CPC group (n = 22) were significantly higher than in the good CPC group (n = 18) at all time points after ROSC except at 4 hours. The time points with highest area under curve were 24 (0.829) and 36 (0.837) hours. The cut-off value, the sensitivity (24/36 hours) and specificity (24/36 hours) for the prediction of poor CPC at 24 and 48 hours were 0.221/0.249 ug/L, 75/65% and 82.4/94.1%, respectively. CONCLUSIONS: Serum S-100B protein was an early and useful marker for the prediction of poor neurological outcomes in post-CA patients treated with TH and the optimal sampling times were 24 and 36 hours after ROSC.

PURPOSE: The purpose of this study was conducted to evaluate the clinical results of proximal tibial plateau fractures treated with open reduction and internal fixation through the lateral submeniscal approach and allowed early motion of the knee and to evaluate the effectiveness of the approach. MATERIALS AND METHODS: From January 1998 to December 2002, fifty four patients who underwent open reduction through the lateral submeniscal approach for proximal tibia plateau fracture and had a follow-up more than one year were included in this study. Clinical results were evaluated by postoperative radiographs taken at the last follow-up and Porter's assessment method. RESULTS: Anatomical reduction was achieved under direct vision through the submeniscal approach in most of the cases in this study. The postoperative radiographs showed anatomical reduction in 32 cases (59%) and adequate reduction with displacement within 2 mm in 20 cases (37%). The clinical evaluation by Porter's assessment method revealed that 49 cases (91%) were acceptable results of excellent or good at the final follow-up CONCLUSION: This study indicates that open reduction and internal fixation through the lateral submeniscal approach can be a good option for proximal tibia plateau fractures because it allows accurate reduction of the articular fractures, which is confirmed directly during operation, identification and repair of associated soft tissue injuries are facilitated, sufficient bone graft and stable fixation of the articular fragments under direct vision allow early motion of the knee.

BACKGROUND:
The extracellular matrix (ECM) has many functions, such as segregating tissues, providing support, and regulating intercellular communication. Cartilage-derived ECM (CECM) can be prepared via consecutive processes of chemical decellularization and enzyme treatment. The purpose of this study was to improve and treat osteoarthritis (OA) using porcine knee articular CECM.
METHODS:
We assessed the rheological characteristics and pH of CECM solutions. Furthermore, we determined the effects of CECM on cell proliferation and cytotoxicity in the chondrocytes of New Zealand rabbits. The inhibitory effect of CECM on tumor necrosis factor (TNF)-a-induced cellular apoptosis was assessed using New Zealand rabbit chondrocytes and human synoviocytes. Finally, we examined the in vivo effects of CECM on inflammation control and cartilage degradation in an experimental OA-induced rat model. The rat model of OA was established by injecting monosodium iodoacetate into the intra-articular knee joint. The rats were then injected with CECM solution. Inflammation control and cartilage degradation were assessed by measuring the serum levels of proinflammatory cytokines and C-telopeptide of type II collagen and performing a histomorphological analysis.
RESULTS:
CECM was found to be biocompatible and non-immunogenic, and could improve cell proliferation without inducing a toxic reaction. CECM significantly reduced cellular apoptosis due to TNF-a, significantly improved the survival of cells in inflammatory environments, and exerted anti-inflammatory effects.
CONCLUSION
Our findings suggest that CECM is an appropriate injectable material that mediates OA-induced inflammation.
