Injuries to the extensor mechanism include a wide range of injuries from minor one to massive defect. And the methods of treatment must be individualized according to the anatomical site, extent and chronicity of injuries. The extensor mechanism is a triangular thin sheet like structure, the function of which cannot be explained completely by the Tubiana's church-steeple like diagram. Authors think that the extensor mechanism should be repaired or reconstructed as a triangular sheet. The tension of the repaired or reconstructed tendon was estimated as good when the neutral extensions were obtained in all the MP, PIP and DIP joints after the completion of sutures. Also authors think that stable sutures are mandatory for the early rehabilitation postopoeratively. Seventy-five patients have been treated by the authors from 1982 to 1994. According to zonal classification, forty-two patients were injured in Zone I. 5 in Zone II, 21 in Zone III, 5 in Zone IV and 2 patients were unclassified due to massive defects of the extensor mechanism. Mostly bony mallet injuries were treated by open reduction and K-wire fixation. Acute tendinous mallet injuries were treated by conservative splinting and old injuries were treated by anatomical plication of the terminal extensor tendon. Old buttonhole deformities were generally treated by the central tendon plication. Massive defects were managed by skin coverage and reconstruction of the extensor mechanism by using a tendon graft which was tailored like a triangular thin sheet. With author's treatment principles, excellent or good results were obtained in about 87%. Consequently, authors emphasize that an anatomical repair or reconstruction is a keystone in the treatment of injuries to the extensor mechanism.

BACKGROUND: Intravascular ultrasound(IVUS) provides high resolution cross-sectional images of the vessels and permits the quantiative and qualitative assessment of coronary artery disease. Stent is a figid endovascular lattice that effectively prevents elastic recoil at treated sites, but in-stent restenois is a major limitation. The purpose of thecurrent study is to assess the contribution of neointimal hyperplasia for in-stent restenosis and the distribution and morphological characteristics of neointimal hyperplasia in deployed stents. METHODS: Thirty patients(male 25 & female 5;31 leions) deployed with intracoronary stents underwent intravascular ultrasound imaging at follow-up at least 4 months after stenting ([mean+/-SD] 8.3+/-2.9 months). RESULTS: 1) In-stent restenosis occurered in 15 lesions out of 31 lesions at follow-up coronary angiography. There was no difference in clinical characteristics between the restenotic and the non-restenotic groups. 2) There was no difference in angiographic profiles between two groups. Deployed stents were as follows ; 16 Palmaz-Schatz(P-S) stents, 12 Gianturco-Roubin(G-R) stents, 2 Cordis stents, and I Microstent II. Average diameter of stents in the restenotic and the non-restenotic groups were 3.07+/-0.26mm and 3.16+/-0.30mm, respectively(p=0.38). 3) There was no difference of stent cross-sectional areas(CSA) between the non-restenotic and the restenotic groups(p=0.476), but luminal CSA of the restenotic group was significantly smaller than that of the non-restenotic group(p=0.006). 4) In the restenotic group, there were no differences of the maximal and the minimal diameters of stents, and the mean CSAs of stents smong proxiaml, mid and distal segments. But the mean CSA of neointimal hyperplasia at the mid segment was larger than that at the distal segment(p<0.05). There was a tendency thatthe mean CSA of neointimal hyperplasia at the mid segment was larger than that at the proximal segment(p=0.187). These findings were the same in the non-restenotic group. 5) In the restenotic group deployed with P-S stents, there were no differences of the maximal and the minimal diameters of stents, and the mean cross-sectional areas(CSA) of stents between each segment. But, the mean CSA of neointimal hyperplasia at the mid segment was larger than that at the distal segment(p<0.005) and there was a tendency that the mean CSA of neointimal hyperplasia at the mid segment was larger than that at the proximal segment(p=0.354). 6) In the morphology of neointimal hyperplasia of the restenotic group, eccentric form(77%) was more common than concentric form(22%). Neointimal hyperplasia occurred in focal or diffuse patterns(7 versus 8 cases). CONCLUSIONS: In-stent restenosis resulted from neointimal hyperplasia which almost mainly occurred eccentrically at the mid segment of stents and in focal or diffuse patterns. Intravascular ultrasound imaging was a useful method for recognition of distribution and morphological characteristics of neointimal hyperplasia at follow-up of deployed stents.

BACKGROUND AND OBJECTIVES: No existing device for cardiopulmonary resuscitation(CPR)isdesignedto exploit both the "cardiac pump" and the "thoracic pump" simultaneously. This study was designed to assess the hemodynamic effects of simultaneous sterno-thoracic CPR (SST-CPR) vs. standard CPR (S-CPR) using a mechanical resuscitator in a canine model of cardiac arrest. DEVICE DESCRIPTION: We have built a device that depresses the sternum and circumferentially constricts the thorax simultaneously. This device has two components. The first component is a piston, which depresses the sternum. The second is a circumferential strap that constricts the thorax as the piston is pushed down on the sternum. MATERIALS AND METHODS: Twelve domestic dogs were enrolled in this study. After catheterizations to measure pressures from the aorta and the right atrium, ventricular fibrillation was induced by passing AC current to the right ventricle. After 4 minutes of cardiac arrest, S-CPR and SST-CPR were performed alternatively. Aortic pressure, right atrial pressure, cardiac output, and end tidal CO2 were measured while each method of CPR was performing. RESULTS: SST-CPR resulted in significantly higher mean arterial pressure than S-CPR (68.9+/-16.1 vs 30.5+/-10.0 mmHg, p<0.01). SST-CPR could generate higher coronary perfusion pressure than S-CPR (47.0+/-11.4 vs 17.3+/-8.9 mmHg, p<0.01). End tidal CO2 tension was also higher during SST-CPR than S-CPR (11.6+/-6.1 vs 2.17+/-3.3 mmHg, p<0.01). CONCLUSION: Simultaneous sternothoracic cardiopulmonary resuscitation is a new method of cardiopulmonary resuscitation, which can generate better hemodynamic effects than standard cardiopulmonary resuscitation.

Aortic interruption is a very rare disease that can be classified into congenital and acquired aortic interruption. Congenital aortic interruption generally implies an interruption of the aortic arch and no case of congenital abdominal aortic interruption has been reported. Acquired aortic interruption, on the other hand, can be caused by atherosclerosis, thrombosis, saddle embolism, and arteritis such as Takayasu arteritis. We experienced a case of congenital abdominal aortic interruption accompanied by one well-developed collateral flow presented with secondary hypertension in a 28-year-old female patient.

Superwarfarin, such as brodifacoum, is a highly lethal vitamin K antagonist used as a rodenticide. Brodifacoum has a particularly long half-life in the body, which ranges to several months, and therefore requires prolonged treatment with antidotal vitamin K. We experienced a case whereby an 18-year-old male was presented to the hospital with a severe bleeding disorder. It was discovered that he had ingested brodifacoum rodenticide with intent to commit suicide. Despite continual treatment with vitamin K, the bleeding disorder persisted for several months before he recovered. We report this case with literature review.

BACKGROUND AND OBJECTIVES: We sought to determine whether an elevated homocysteine (Hcy) level is associated with a worse prognosis in Korean patients with coronary artery disease (CAD). SUBJECTS AND METHODS: A total of 5839 patients (60.4% male, mean age 61.3±11.2 years) with CAD were enrolled from 2000 to 2010 at Gangnam Severance Hospital. CAD was diagnosed by invasive coronary angiography. Laboratory values including Hcy level were obtained on the day of coronary angiography and analyses were performed shortly after sampling. Patients were divided into two groups according to their Hcy levels. Baseline risk factors, coronary angiographic findings, length of follow-up, and composite endpoints including cardiac death (CD) and non-fatal myocardial infarction (NFMI) were recorded. 1:1 propensity score matched analysis was also performed. RESULTS: Over a mean follow-up period of 4.4±2.5 years, there were 132 composite endpoints (75 CD and 57 NFMI) with an event rate of 2.3%. Mean Hcy level was 9.9±4.3 µmol/L (normal Hcy 7.9±1.5 µmol/L and elevated Hcy 13.9±5.1 µmol/L). Kaplan-Meier survival analysis showed an association of elevated Hcy level with worse prognosis (p<0.0001). In addition, a multivariate Cox regression analysis showed an association of elevated Hcy level with worse prognosis for both the entire cohort (hazard ratio [HR] 2.077, 95% confidence interval [CI] 1.467-2.941, p<0.0001) and the propensity score matched cohort (HR 1.982, 95% CI 1.305-3.009, p=0.001). CONCLUSION: Elevated Hcy level is associated with worse outcomes in Korean patients with CAD.

Emergency physicians often have to treat patients suffering from testicular pain. Testicular torsion is a critical disease which can, in the worst situation, require orchiectomy. Testicular torsion is more common among neonates and adolescents than adults, and there are very few adults reported to have testicular torsion. There are several cases of testicular torsion among adults aged 20 to 40. However, there have been almost no reports of patients with testicular torsion over the age of 50. Patients over the age of 50 have a greater possibility of a delayed diagnosis. Therefore, they also have a greater possibility of requiring an orchiectomy. In our case, 57-year-old male patient complained of testicular pain that developed during his sleep after golf practice. After exploratory surgery, he was diagnosed as having testicular torsion. In conclusion, emergency physicians should consider the possibility of testicular torsion when older adults complain of testicular pain. Also, patients who suffer from intermittent testicular pain show higher rates of developing testicular torsion.

It is very difficult to discern edible mushrooms such as Naematololma sublateritium from toxic mushrooms such as Naematololma. fasciculare in the natural environment. We experienced a case of a patient who accidentally ingested Naematololma. fasciculare. The patient was admitted to the emergency department with nonspecific abdominal symptoms such as nausea, vomiting, abdominal pain and diarrhea. Treatment involved supportive care instead of gastric lavage and charcoal, since their effectiveness is unproven for relief of mushroom intoxication.

Fluconazole is a fungistatic agent that is used for treating systemic and superficial fungal infections like onychomycosis and tinea pedis. Various adverse effects of fluconazole have been reported regardless of the total dosage and the duration of treatment. We consider the number of patients who visit the emergency room with nonspecific symptoms that are related to antifungal agents are not inconsiderable. In this case, 44-year-old male patient experienced mental change during taking fluconazole to treat tinea pedis. The understanding of the side effects and the drug interactions with antifungal agents like fluconazole can help to treat patients with nonspecific symptoms that are related to antifungal agents.
