PURPOSE: Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament(ACL) injury in MR image. MATERIAL AND METHODS: The knee MR images of 47 patients with ACL injury(complete; 24, partial; 23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament(PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. RESULTS: The means( +/- 2standard errors) of anterior translocation were different significantly in statistical analysis(p<0.001, student t-test) between injury group(7.51 +/- 1.16mm) and normal group(-0.56 +/- 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically b. etween injury group(0.23 +/- 0.02) and normal group(0.17 +/- 0.01)(p<0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear(66%), thirteen lateral meniscus tear(28%), ten medial collateral ligament injury(28%), one PCL injury (2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients {43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients(19%) and avulsion fractures of anterior tibial spine in four patients(9%). CONCLUSION: The associated findings with ACL injury (anterior translocation, buckling of PCL, associated bone, ligament and meniscus injuries) are considered to be helpful in the diagnosis of ACL injury on Knee MR images, when the findings of anterior cruciate ligament itself are not confirmative.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) strategy is proposed to reduce the ventilator-induced lung injury in acute respiratory distress syndrome (ARDS). As ECMO use has increased, a number of studies on prognostic factors have been published. Age is estimated to be an important prognostic factor. However, clinical evidences about ECMO use in elderly patients are limited. Therefore, we investigated clinical courses and outcomes of ECMO in elderly patients with ARDS. METHODS: We reviewed medical records of patients with severe ARDS who required ECMO support. Study patients were classified into an elderly group (> or = 65 years) and a non-elderly group (< 65 years). Baseline characteristics, ECMO related outcomes and associated factors were retrospectively analyzed according to group. RESULTS: From February 2011 to June 2013, a total of 31 patients with severe ARDS were treated with ECMO. Overall, 14 (45.2%) were weaned from ECMO, 9 (29.0%) survived to the general ward and 7 (22.6%) survived to discharge. Among the 18 elderly group patients, 7 (38.9%) were weaned from ECMO, 4 (22.2%) were survived to the general ward and 2 (11.1%) were survived to discharge. Overall intensive care unit survival was inversely correlated with concomitant acute kidney injury or septic shock. CONCLUSIONS: In this study, ECMO outcome was poor in severe ARDS patients aged over 65 years. Therefore, the routine use of ECMO in elderly patients with severe ARDS is not warranted except in highly selective cases.

Allopurinol (4-hydroxypyrazolo[3, 4-d]pyrimidine) is a xanthine oxidase inhibitor and is widely used in the treatment of hyperuricemia. Allopurinol hypersensitivity syndrome (AHS) includes a prolonged illness initially manifested by fever, a prominent cutaneous reaction, eosinophilia, hepatic abnormalities, and decreased renal function. Two patients in our study had a decreased renal function; one due to bilateral polycystic kidneys and the other due to bilateral ureteral stones. Both had received allopurinol for asymptomatic hyperuricemia. Whilst taking this medication, they showed a generalized erythematous, maculopapular eruption with fever, leukocytosis, eosinophilia, a further decrease of renal function and prolonged severe hepatic abnormalities. One patient showed an improvement after they stopped taking allopurinol and were treated with steroids, however, died, due to combined giant cell pneumonia. However, the other patient did improve when they stopped taking allopurinol.

BACKGROUND: Pulse wave velocity (PWV) and pulse transit time (PTT) are influenced by the arterial wall stiffness and compliance. Also, the PTT is dependent on blood pressure changes that can be accompanied by the anesthesia. The simply measured PTT has difficult to discriminate the arterial compliance changes from blood pressure changes. Therefore, we investigated that the differences of PTT between toe and finger as an independent parameter on blood pressure. METHODS: Eighteen patients scheduled for elective lower abdominal gynecologic surgery were studied. General anesthesia was achieved with sevoflurane and epidural block was done with 0.2% ropivacaine and fentanyl 100microgram via epidural catheter inserted into L1 - L2 epidural space. PTT was measured in a finger (PTTf) and a toe (PTTt) by the time difference between the ECG R wave and the pulse wave of PPG. Blood pressure and PTT was measured at three instances such as preinduction (Pre), 5 minutes after intubation (Int5) and 30 minutes after injection of epidural dose (Epi). The time delay of PTT between toe and finger (PTTt-f) was measured. RESULTS: PTTf and PTTt was prolonged at Int5 and Epi. But the PTTt-f was not different between the Int5 and Epi because of prolonged PTTf caused by the blood pressure decrement after the epidural block. CONCLUSIONS: PTTf, PTTt and PTTt-f can be a one of the convenient measurement of the arterial compliance but it was suggested that there need to be a parameter less dependent on the blood pressure changes.

The inflammatory pseudotumor of the urinary bladder is rare, especially in children. It is a benign proliferative lesion of the submucosal stroma easily mistaken for a sarcoma clinically, so it should be differentiated from a malignant neoplasm. We report the case of bladder inflammatory pseudotumor in a 7-year-old girl.

BACKGROUND: Arginine vasopressin has been used by prophylactic treatment of vasodilatory shock during coronary artery bypass graft (CABG). Vasopressin may be a cause of spasm in graft artery during CABG. We evaluated the effect of propofol on vasopressin-induced contraction in human gastroepiploic artery (GEA). METHODS: Human GEA were obtained from 35 patients (43-74 yr), undergoing subtotal gastrectomy. Vasopressin-induced a concentration contractions (10(-9) to 10(-6) M) were measured after exposed to without propofol, propofol 10(-5), 10(-4), 10(-3) M. After endothelium denuding vasopressin-induced a concentration contractions were measured with or without propofol 10(-3) M in calcium free solution. In the denuded vascular rings, with or without pretreatment of glibenclamide (10(-5) M), nicorandil (10(-5) M), or diltiazem (10(-5) M) were exposed to with or without propofol 10(-3) M, and vasopressin-induced concentration contractions were measured. RESULTS: Vasopressin-induced concentration contraction on human GEA was independent of functional endothelium. Propofol (10(-4), 10(-3) M) attenuated the vasopressin-induced contraction in the human GEA. Diltiazem attenuated the vasopressin-induced contraction in the human GEA. ATP-sensitive potassium channel does not affect the inhibition effect of propofol on vasopressin-induced contraction CONCLUSIONS: Usual anesthetic dose of propofol does not inhibit vasopressin-induced contraction on human GEA. High dose (>10(-4) M) propofol attenuated vasopresssi-induced contraction on GEA.

BACKGROUND: Mesenchymal stem cells can be expanded rapidly in vitro and differentiated into multiple mesodermal cell types. This study was planned to isolate human adipose tissue stromal cells (hATSCs) from human liposuction tissues and to investigate the changes of tactile threshold after hATSC transplantation in animal neuropathic pain models. METHODS: hATSCs were grown under control conditions in alpha-MEM/10% FBS. To prepare neuropathic pain model rats, thirty male Sprague-Dawley rats that had the average body weight of 208 +/- 5 g, had an experimental nerve injury by cutting or clamping of sural and tibial nerves. The tactile threshold was measured by von Frey hair filament at preinjury and postoperative day (POD) 1, 2, 3, 7, 14. Transplantation of hATSCs was performed after measurement of tactile threshold at POD3. RESULTS: hATSCs grew as a monolayer of large, flat, and spindle-shaped cells. The tactile threshold after spared nerve injury was significantly decreased since one day after cutting or clamping of nerves (P < 0.01). The percent changes of a tactile threshold in clamping and hATSC group were decreased to 59.8 +/- 7.1% (POD7) and 52.6 +/- 5.1% (POD14) (P < 0.05). CONCLUSIONS: This results was suggested that hATSCs could be isolated from human adipose tissue easily. Althogh it needs more long-term investigation hATSCs might be used as a method of therapy for neuropathic pain.
