Purpose: Endovascular treatment for peripheral arterial obstructive disease (PAOD) is replacing traditional arterial bypass in the western world. Yet there are few reports to evaluate the pattern of clinical practice pattern for PAOD in Korea. This study was conducted to evaluate the treatment pattern for PAOD between endovascular treatment and arterial bypass, and to compare their clinical characteristics. Methods: We conducted a retrospective study on the prospectively maintained database of patients who underwent endovascular treatment and arterial bypass for PAOD from March 2005 to December 2009 in Inha University Hospital. The aortoiliac lesions and femoropopliteal lesions were categorized by the Trans Atlantic Inter-Society Consensus (TASC) II classifications. Their treatments and clinical characteristics were compared between the former period (2005∼2007 y) and the latter period (2008∼2009 y). Results: Three hundred nine cases (178 patients) were treated for PAOD by either arterial bypass or endovascular treatment. The patients’ mean age was 69.1±11.3 year old. There was no difference in clinical characteristics between the two periods except for age. Endovascular treatments of both aortoiliac and femoropopliteal arterial lesions were increased in the latter period (P=0.023, P<0.001). Also, the endovascular treatments were increased in the TASC C and D aortoiliac and femoropopliteal lesions in the latter period (P=0.020, P<0.001). Conclusion: Endovascular treatment for PAOD is increasing in clinical practice and this shows feasibility in critically ill patient with TASC C and D lesions, although arterial bypass is still important.

A 62-year-old man with progressive swelling on his left thigh and leg was referred to the Division of Vascular Surgery. Anticoagulation therapy did not prevent or improve the symptoms of chronic deep vein thrombosis (DVT) from his left external iliac vein to posterior tibial vein. He had no trauma history nor any accidents. He underwent femoral endovenectomy, thrombectomy and stent insertion in left iliac vein. The patient had additional balloon angioplasty for stenosis in left common femoral vein. He had an uneventful postoperative recovery without complication. Leg swelling has been improving and follow-up continues under anticoagulation. We report a case of femoral endovenectomy with iliac stenting, which may be an efficacious treatment for chronic DVT.

This study was designed to evaluate the relationship of mandibular condylar position to overbite depth and compare the findings from transcranial radiographs and those from indivisualized corrected tomographs in determination of condylar position. The subjects consisted of 20 control subjects(male 8, female 12), and 23 deep-bite patients(male 17, female 6). The mean age was 23.6 years for the control group, and 23.2 years for deep-bite group. Transcranial radiographys and individualized corrected tomographys in centric occlusion were taken from right and left temporomandibular joints of each subject. The results were as follows. In the 20 normal subjects showing no symptoms of TM disorder, the incidence of condylar retrusion was 27.5%, middle condylar position 60.0%, and anterior displacement 12.5%. Only 45.2% of the findings from transcranial radiographs coincided with those from individualized corrected tomographs in determining condylar position. There was significant correlation between the bite depth and observed condylar position.

Thermography is a sensitive and reliable method for diagnosis of temporomandibular joint disorder. Digital infrared thermographic imaging system is noninvasive, easy to reading, objective and physiologic instrument by measuring and imaging infrared energy emitted from skin surface. Computerzed digital infrared thermographic imaging is comfortable method for diagnosis of disease and evaluation for treatment result. The author presents the result of digital infrared thermographic images of 36 patients of temporomandibular disorder. The author has done digital infrared thermographic imaging preconservative and postconservative treatment. In digital infrared thermographic imaging before use of occlusal stabilization splint, the diagnostic sensitivity is about 83.3%. In digital infrared thermographic imaging after use of occlusal stabilization splint, the result is about 73.3%.
X 線照射가 發育齒根膜에 미치는 影響에 關한 實驗的 硏究

The author studied on the effects of X-ray irradiation to the development of periodontal ligament in gestation rats. They were irradiated in their abdomen with 100, 200 and 300 rads respectively in one shot irradiation with deep radiation therapy equipment(MAXIMAR 250-III). In 7th, 14th, 21th and 28th day after delivery, those new born rats were respectively sacrificed with ether anesthesia and removed of their mandibles. After removal, those mandibles were fixed in 10% neutral buffer formalin, decalcified with 5% trichloroacetic acid for 5 days and embedded with paraffine. Staining was performed with H-E, Van Gieson, Mallory azan, Bielshowsky-Gomori silver stain and Halmi's oxytalan fiber stain. The results were as follows: 1. Before tooth eruption, all the fiber components in dental sac were almost always oriented near the outer enamel epithelial layer. But in irradiated new born rats, those collagen fiber orientation was more irregular than those of control groups, and this phenomenon was more severe in proportion to the amount of irradiation in the gestation period. 2. Before tooth eruption, the connective tissue fibers in periodontal ligament were stained with lighter in irradiated groups than those of control groups. Oxytalan fibers of irradiated groups were thin and splitting pattern of their fiber morphology to compare with those of control groups. 3. After tooth eruption, the periodontal ligament fibers of irradiated groups were oriented functionally and their morphology was thick, fine and heavy staining. Oxytalan fibers were revealed with oblique parallel arrangement in the periodontal ligament of irradiated groups.
