BACKGROUND: The mechanically ventilated patient's stay in the emergency department (ED) is brief but ventilatory management and intervention must be optimal. Agitation, anxiety, distress, and discomfort are common complications far the ventilated patient. So, sedation is necessary to reduce these complications. METHODS: Patients were monitored and mechanically ventilated. Midazolam was intravenously administered as loading dose(3-5mg), followed by continuous infusion at a rate of 0.06mg/kg/hr, titrated to achieve a predetermined sedation level (Ramsay's sedation score: 2-5 points, Glasgow coma score scathe : 8-11 points). RESULTS: After onset of predetermined sedation, systolic and diastolic blood pressure and heart rate remained stable during continuous infusion when compared with those of the initial state. Arterial blood gas and peak inspiratory pressure remained unchanged but respiratory rate was decreased to allowable ranges. CONCLUSION: A short-term continuous infusion of midazolam was a safe and erective method for sedation of ventilated patients in ED.

OBJECTIVE: This study was done to evaluate the risk factors and prevalence of symptom-giving pelvic girdle relaxation in pregnant women. METHODS: Three hundreds thirty-two postpartum women were asked to fill out a questionnaire within one week after their parturition. The diagnostic criteria of this lesion were adopted from the Norwegian Medical Association's and Larsen's criteria. The questionnaire were included age, parity, BMI(kg/cm2), weight gain during the pregnancy, history of symptom giving pelvic girdle relaxation in previous pregnancy, level of exercise and vocational status during and before the pregnancy and baby's birth weight. The answers were evaluated to determine the risk factors. The correlation was tested by student t-test and logistic regression. RESULTS: The prevalence of symptom-giving pelvic girdle relaxation during pregnancy was 18.9%. The history of symptom-giving pelvic girdle relaxation in previous pregnancy, multiparity and the absence of regular exercise before and during pregnancy showed correlation with symptom-giving pelvic girdle relaxation in pregnancy (p<0.05). CONCLUSION: It is suggested that women who experienced symptom-giving pelvic girdle relaxation in previous pregnancy should be checked for this lesion before pregnancy. Regular exercise is required to lower the incidence and lessen the severity of this lesion in pregnancy.

Sciatic nerve palsy after total knee arthroplasty, accompanied by motor power weakness and electromyographic evidence, is a rare occurrence. In a 78-year-old female, pneumatic tourniquet was used for 72 minutes, with a pressure of 300 mmHg. The time and pressure are generally accepted values. We noticed sciatic nerve palsy showing motor power weakness and electromyographic evidence. One year after the operation, she recovered full motor power, but complained about a tingling sensation below the knee. Given that the nerve injury after using tourniquet was due to neural ischemia, and since our patient had vascular circulation problems such as atrial fibrillation and clip insertion due to internal carotid artery aneurysm, our patient can be considered as a high-risk patient with weakness to neural ischemic damage, even with the use of conventional tourniquet. Therefore, surgeons should be cautious when using tourniquet in patients with vascular circulation problems.

A fibroma of the tendon sheath (FTS) is a rare and less well-known benign soft-tissue tumor. FTS infrequently develop in the knee region. Especially intraarticular FTS of the knee was found in a few case reports. We present a rare case of FTS arising from the infrapatellar plica of the knee in 12-year-old man without a history of specific trauma. Magnetic Resonance Imaging (MRI) and an arthroscopic examination revealed an encapsulated soft tissue mass arising from the infrapatellar plica anterior to the anterior cruciate ligament. The histological diagnosis is FTS in the intraarticular of the knee. To the best of our knowledge, this report is the first reported case of FTS involving the infrapatellar plica of the knee.

One of the purposes of this experiment is to observe the structure of crystalline lens with cataract, which is formed artificially, using the light microscope and electron microscope. The other is to observe the differences of structural variations in the cataract developed inside body. Twelve eyes of six pigs were used for this experiment. Two of them are normal crystalline lens, five are cystalline lens in distilled water, and the rest are in balanced salt solution through intact or ruptured capsule. We examined the time of cataract formation and compared the ultrastructural changes. Ruptured capsule and high osmotic pressure difference induced more rapid opacity. In case of distilled water, the capsule is maintained but it is very difficult to distinguish between epithelium and lens fibers. Also, there is a severe crack in the lens fibers. In electron microscopic, as the cataract progresses, the osmotic swelling becomes more prominent. One of the striking changes was a marked intercellular cyst formation. Lens cells became irregular in size and density and were extensively vacuolated. The swelling of the lens cells continuously induced large intracellular vacuoles and liquefied the cytoplasmic protein. In conclusion, the structural change of cataract, which was seen by an electron microscope, resulted from change in osmolarity from previously announced in vivo experiment and structural change resulted from this experiment are similar.

Some variables can influence the efficiency of leukocyte removal filter for red cell concentrates. We performed this study to evaluate whether the filtration efficiency for platelet concentrates(PCs) can be influenced by bedside filter(PXL8K, Pall Corporation, USA) used, platelet storage time and transient stopping of platelet agitation, and to measure the amount of cytokines released from donor leukocytes in PCs during the storage time. In addition, we examined the effect of leukocyte reduction by filtration before the storage of PCs on the subsequent generation of cytokines. Any of the above mentioned variables did not make significant differences. From day 1 to day 5, there were significant increases in IL-1 beta (<1 vs. 8.6 pg/mL, p<0.05), IL-8 (<10 vs. 455.3 pg/mL, p<0.05) and TNF-alpha (<4 vs. 16.6 pg/mL, p<0.05) in unflltered PCs, whereas no increased revels of cytokines were found in the cases of prestorage filtration.

STUDY DESIGN: Case report. OBJECTIVES: To report a case of epidural hematoma following cervical spinal fracture in a patient with ankylosing spondylitis. SUMMARY OF LITERATURE REVIEW: An early surgical intervention for acute epidural hematoma following cervical spinal fracture led to improvements in the patient's neurological deficits. MATERIALS AND METHODS: A 76-year-old male with ankylosing spondylitis presented with neck pain and motor weakness of both upper and lower extremities after falling. He sustained fractures of the C7 body and the spinous processes of C5 and C6. Magnetic resonance imaging showed an extensive epidural hematoma from C7 to T5. The authors performed decompression from C6 to T2, and posterior instrumentation and fusion from C4 to T3. RESULTS: An urgent surgical intervention was performed, and a good result was obtained. CONCLUSIONS: The authors describe an early surgical intervention in a case of acute epidural hematoma following cervical spinal fracture in a patient with ankylosing spondylitis.

PURPOSE: Prompt reperfusion therapy by means of primary percutaneous coronary intervention is an effective method for treating patients with ST-segment elevation myocardial infarction (STEMI). According to the ACC/AHA guidelines for these patients, the interval between arrival at the hospital and intracoronary balloon inflation (door-to-balloon time) should be 90 minutes or less. The aim of this study was to evaluate the effect of establishing an ECG transmission system and communication procedure in the emergency department (ED) to minimize door-to-balloon time for STEMI patients. METHODS: We established both the out-of hospital and in-hospital aspects of the ECG transmission system. Before patient arrival at our ED, we would attempt to receive initial ECGs from the referring hospitals via fax. In ideal cases, ECG findings were immediately reported to interventional cardiologists by the referring primary ED physician. Door-to-balloon time segments were analyzed in a retrospective manner. We compared the effectiveness in minimizing reperfusion time between the use of inter-hospital 12-lead ECG transmission before patient arrival, and direct communication between emergency physicians and attending interventional cardiologists. RESULTS: Of the total 142 STEMI patients who received percutaneous coronary intervention (PCI) during the study period, 112 (78.9%) received PCI within 90 min. The mean door-to-balloon time of the 27 patients admitted with a pre-arrival 12-lead ECG transmission was significantly less than the others. CONCLUSION: Establishing both out-of hospital and in hospital strategies to reduce door-to-balloon time in patients with STEMI, by using pre-arrival ECG transmission and direct communication between emergency physicians and interventional cardiologists, is an effective approach to minimize time to reperfusion.

BACKGROUND: Psoriatic lesions have reduced water-holding capacity and show increased transepidermal water loss (TEWL). The effect of D-PUVA therapy, which combines topical calcipotriol and PUVA therapy, on epidermal barrier function has not yet been evaluated. OBJECTIVE: The purpose of this study was to verify the change of TEWL in lesional and normal skin according to D-PUVA therapy in psoriasis patients. METHODS: TEWL was measured consecutively by TEWAMETER TM210®, in 13 psoriasis patients who received D-PUVA therapy. Clinical grading was done according to psoriasis severity index (PSI). RESULTS: TEWL of psoriatic lesion decreased as D-PUVA continued. TEWL of normal-looking skin gradually increased, although the increase was trivial. Clinical grading of scale and in-filtration followed the pattern of PSI in the decrease of TEWL, while that of erythema did not. CONCLUSION: In psoriatic plaques, TEWL was decreased according to the improvement. In normal-looking skin, D-PUVA therapy caused only a little effect on TEWL.

PURPOSE: Asthma is prevalent in many countries. Few studies have investigated the association between asthma and concomitant diseases. We retrospectively analyzed the fourth Korean National Health and Nutrition Survey database, performed in 2008 using nationwide stratified random sampling to obtain a representative cohort of the Korean population. METHODS: We evaluated the association between both self-reported ever-asthmatics and wheezers and concomitant diseases such as arthritis, hypertension, gastrointestinal (GI) ulcers, dyslipidemia, diabetes mellitus, rhinitis, depression, stroke, and obesity in subjects aged > or =40 years. A multivariate analysis was performed to identify concomitant diseases independently associated with asthma, after adjustment for age, gender, income, cigarette smoking, and other chronic diseases. RESULTS: Of the total of 4,445 subjects, 2,596 (58.4%) were female and the mean age was 58.3 years. Of the 4,445 subjects, 195 (4.4%) had been diagnosed with asthma at some point, and 444 (10%) were wheezers. Multivariate analysis showed that arthritis (odds ratio [OR] 1.74, 95% confidence interval [CI] 1.26-2.42), rhinitis (OR 1.78, 95% CI 1.14-2.78), depression (OR 1.45, 95% CI 1.05-2.07), and obesity (OR 1.61, 95% CI 1.08-2.40) were significantly associated with self-reported ever-asthma, and arthritis (OR 1.50, 95% CI 1.19-1.909), hypertension (OR 1.34, 95% CI 1.07-1.67), GI ulcers (OR 1.48, 95% CI 1.05-2.08), rhinitis (OR 1.60, 95% CI 1.16-2.19), depression (OR 1.94, 95% CI 1.51-2.48), and obesity (OR 1.56, 95% CI 1.17-2.09) were significantly associated with wheezers. CONCLUSIONS: These findings indicate that arthritis, rhinitis, depression, and obesity may be associated with both self-reported ever asthma and wheezers in the Korean population.
