Thermography is a sensitive and reliable method for diagnosis of radiculopathy. Skin temperature alterations of the involved dermatome named thermatone are diagnostic for sensory root involvement in radiculopathy which can be demonstrated by thermography. Digital infrared thermographic imaging system using computer is development and could measure thermal difference more exactly without hazards or discomforts to patient. Authors present 186 cases of thermographic evaluation in herniated lumbar disc disease by digital infrared thermographic imging system and the results are evaluated with literature review.

The p53 gene is believed to play an important role through the mutation and overexpression in the progression of various human malignant tumors. The type IV collagenase (matrix metalloproteinase: MMP-2) initiates the degradation of the extracellular matrix, and consequently may play a role in the tumor invasion and metastasis. To investigate the correlation between clinicopathologic features of the colorectal adenocarcinomas and benign tumors and expression of p53 and MMP-2 proteins, we performed an immunohistochemical study on 40 colorectal adenocarcinomas, 20 adenomas and 20 hyperplastic polyps by using the antibodies to p53 and MMP-2 proteins. The positive expression rate of the p53 protein in adenocarcinomas was 62.5% and significantly higher than in benign tumors. The positive expression rate of the MMP-2 protein was 47.5% in adenocarcinomas, but there was no expression of MMP-2 protein in benign tumors. The difference in p53 and MMP-2 expression rates between malignant and non-malignant tumors was statistically significant. The positive expression rate of p53 protein in the non-metastatic and metastatic adenocarcinomas was 59.1 and 66.7%, respectively. The positive expression rate of MMP-2 protein in the non-metastatic and metastatic adencarcinomas was 45.5 and 50.0%, respectively. The correlation between several clinicopathologic features and expression of p53 and MMP-2 protein was not statistically significant, but the rate of positive MMP-2 immunoreactivity showed a statistically significant difference between Astler-Coller stage B1 C1 group and B2 C2 group of adenocarcinoma (p=0.0431). We concluded that the expression of p53 and MMP-2 protein contributes to the cancer development and MMP-2 may play a certain role in the invasiveness of the colorectal tumor. p53 and MMP-2 protein expression is not correlated with lymph node metastasis.

BACKGROUND: The risk of bleeding during extracorporeal membrane oxygenation (ECMO) is a potential deterrent in performing tracheostomy at many centers. To evaluate the safety of surgical tracheostomy (ST) in critically ill patients supported by ECMO, we reviewed the clinical correlation between preoperative coagulation status and bleeding complication-related ST during ECMO. METHODS: From April 1, 2012 to March 31, 2016, ST was performed on 38 patients supported by ECMO. We retrospectively reviewed and analyzed the medical records including complications related to ST. RESULTS: Heparin was administered to 23 patients (60.5%) for anticoagulation during ECMO, but 15 patients (39.5%) underwent ECMO without anticoagulation. Of the 23 patients administered anticoagulation therapy, heparin infusion was briefly paused in 13 prior to ST. The median platelet count, international normalized ratio, and activated partial thromboplastin time before ST were 126 ×109/L (range, 46 to 434 ×109/L), 1.2 (range, 1 to 2.3) and 62 seconds (27 to 114.2 seconds), respectively. No peri-procedural clotting complications related to ECMO were observed. Two patients (5.3%) suffering from ST-related major bleeding required surgical hemostasis. Minor bleeding after ST occurred in two cases (5.3%). No significant difference was found according to anticoagulation management (P = 0.723). No fatality was attributable to ST. CONCLUSIONS: The complication rates of ST in the patients supported by ECMO were low. Therefore, ST performed by an experienced operator, and with careful optimization of coagulation status, is a relatively safe procedure; the use of ST with ECMO should thus not be dismissed on account of the potential for bleeding caused by the administration of anticoagulants.

Proper positioning of pulmonary artery catheter and predicting distal migration of it during cardiopulmonary bypass is important for the prevention of perioperative complication of pulmonary artery rupture. The authors therefore examined the insertion length of pulmonary artery catheter via right internal jugular vein at which catheter tip was advanced to the most proximal position where pulmonary capillary wedge pressure could be obtained. And also the distal migration is measured by comparing the difference between prebypass and postbypass corrected length. Just before bypass, pulmonary artery catheter was arbitrarily receded 5cm for the prevention of spontaneous distal migration and wedging. The subjects were 47 patients who underwent open heart surgery (valve replacement, coronary artery bypass graft) during the period of November, 1992 through April, 1993. The results were as follows. 1) The insertion length of pulmonary artery catheter from skin to the right ventricle inlet, pulmonary artery inlet and pulmonary capillary wedge position were 26.5+/-3.0 cm, 36.8+/-4.9 cm and 46.1+/-5.7 cm respectively. 2) There were no significant statistical correlations between insertion lengths and patient constitutions such as body weight and height(r=0.144, r=0.032). 3) Locations of catheter tips were distributed to the 0.9+/-3.1 cm left to the spinous process, 1.9+/-1.6 cm inferior to the carina ; mostly LLQ of the lung field(51%). 4) During cardiopulmonary bypass, pulmonary artery catheter tips were migrated distally in 93.6% of the cases and the migration lengths were 2.7+/-2.0 cm. 5) There were no major perioperative complications caused by pulmonary artery catheterization. These results suggest that 5 cm withdrawal of pulmonary axtery catheter just before cardiopulmonary bypass can prevent the fatal complication of pulmonary artery rupture owing to its spontaneous distal migration.

Spinal fusion has performed for instability and anatomical reconstruction since 1985 by Barthe. Bone grafts and synthetic materials has been used for spinal fusion, but they have several limitations and complications. Recently a new synthetic polymer B.O.P.(Biocompatible Osteoconductive Polymer) was developed and it overcome the limitations of other materials. The B.O.P. showed no foreign body reaction and gave scaffolding for the osteoconduction and osteointegration. Authors operated 35 cases of spinal fusion with B.O.P. and the results and literature reviews were discussed.

Anterior interbody fusion has used for instability and anatomical reconstruction in various cervical diseases since 1958 by cloward. Bone grafts such as autograft, allograft, xenograft and synthetic materials were utilized in fusion as a graft material. But conventional fusion materials have problems including postoperative morbidity, transmission of diseases, foreign body reaction, collapse, prolongation of operation time. A new synthetic material, Biocompatible Osteoconductive Polymer(B.O.P) is developed and it was useful for cervical anterior interbody fusion as a substitute for other fusion materials.
