The Journal of the Korean Orthopaedic Association 1969;4(1):35-39
Clinical analysis of fracture of femral shaft in 73 cases treated at the 17 Army Hospital during the period from May 1965 to July 1968 is presented. 1) All the patient were males and in the 3rd decade of life. 2) Sites of fracture were 28 in midshaft, 23 in lower one-third, 22 in upper one-third, and 29 cases: had open fracture. 3) 32 cses(43.8%) were injured by traffic accident which is the most common cause in this series. 4) Conservative treatmet was given in 30 cases, plate fixation in 15 cases, and Kuentscher type of I.M. nailing in 28 cases. 5) Criteria evaluating the results were; knee joint motion, length & alignment of the femur, and pain during weight bearing. 6) Severely comminuted fracture tends to deserve conservative measure only and sites of fracture contraindicated for I.M. nailing were best treated by plate or screw fixation. 7) A comparison has been made between the functional results treated by conservative method and open reduction (plate & screw fixation and I.M. Kuentscher nailing). Excellent or good results were obtained, by conservative (30 cases), plate and screw fixation. (15 cases), and I.M. Kuentscher nailing(28cases), in 46.7%, 60%, and 60.7% respectively. Functional results were slightly better in I.M. nailing than the other two methods. 8) Time of complete healing by solid bone union was; 6.5 months in (30 cases of) conservative treatment, 6 months in (10 cases of) plate and screw fixation, and 5.5 months in (22 cases of) I.M. Kuentscher nailing. 9) Postoperative infection rate,severe enough to interfere healing) was 6.6% (only one case) of plate group and 3.6%(only one case) of I.M. nailing group.

OBJECTIVES: For the understanding and effective treatment of depressive symptoms in chronic schizophrenia, this study investigated the frequency of depressive symptoms and examined associations between depressive symptoms and positive symptoms, negative symptoms, general psychopathology in chronic schizophrenia. METHOD: The authors assessed the frequency of depressed schizophrenia with 30 or higher scores of HRSD in 135 DSM-IV chronic schizophrenia. We measured PANSS, BPRS in depressed(n=37) and non-depressed schizophrenia(n=37) who were matched in sex, age and dose of antipsychotics to compare positive, negative symptoms and other psychopathology. Also, we evaluated correlation between depressive symptoms and positive symptoms, negative symptoms, other psychopathology in depressed schizophrenic patients. RESULTS: 1) The depressive symptoms were present in 27.4% of chronic schizophrenia. 2) The positive scale of PANSS were significantly higher in depressed than in non-depressed schizophrenia(p<.01), and the negative scale of PANSS were higher in depressed schizophrenia but there were no statisical significance. Thinking disturbance and depressive-anxiety factors of BPRS were significantly higher in depressed than in non-depressed schizophrenia(p<.01, p<.01). 3) The positive and negative scale of PANSS correlated with HRSD in depressed schizophrenia(p<.01, p<.05), and thinking disturbance and depressive-anxiety factors correlated with HRSD in depressed schizophrenia(p<.01, p<.01). CONCLUSION: The depressive symptoms are relatively commom and important part of schizophrenic symptomatology, and they are more related to positive symptoms than negative symptoms of schizophrenia. Thus this study suggest that appropriate assessment and therapeutic intervention for depressive symptoms is especially necessary to the schizophrenic patients with severe positive symptoms.

OBJECTIVE: To evaluate spine magnetic resonance imaging (MRI) inter-reader and intra-reader reliabilities using the thoracolumbar injury classification system and severity score (TLICS) and to analyze the effects of reader experience on reliability and the possible reasons for discordant interpretations. MATERIALS AND METHODS: Six radiologists (two senior, two junior radiologists, and two residents) independently scored 100 MRI examinations of thoracolumbar spine injuries to assess injury morphology and posterior ligamentous complex (PLC) integrity according to the TLICS. Inter-reader and intra-reader agreements were determined and analyzed according to the number of years of radiologist experience. RESULTS: Inter-reader agreement between the six readers was moderate (k = 0.538 for the first and 0.537 for the second review) for injury morphology and fair to moderate (k = 0.440 for the first and 0.389 for the second review) for PLC integrity. No significant difference in inter-reader agreement was observed according to the number of years of radiologist experience. Intra-reader agreements showed a wide range (k = 0.538-0.822 for injury morphology and 0.423-0.616 for PLC integrity). Agreement was achieved in 44 for the first and 45 for the second review about injury morphology, as well as in 41 for the first and 38 for the second review of PLC integrity. A positive correlation was detected between injury morphology score and PLC integrity. CONCLUSION: The reliability of MRI for assessing thoracolumbar spinal injuries according to the TLICS was moderate for injury morphology and fair to moderate for PLC integrity, which may not be influenced by radiologist' experience.

Various periodontal barrier membranes used in many clinical and experimental fields, and many recent studies of membranes have reported good results. To improve clinical results, selection of barrier membranes is an important factor. So, we need not only to evaluate various barrier membranes, but also to understand the property of barrier membranes appropriate to defect characteristics. For this purpose, this study reviewed available literature, evaluated comparable experimental models, and compared various barrier membranes. From above mentioned methods, the following conclusions are deduced. 1. In 1-wall periodontal defect models, new bone formation showed a consistent result, almost 30% of the defect size. New cementum formations measured mostly 40% of the defect size, but showed more variations than new bone formations. This seems to be resulted form difference in experimental methods, so standardization in experimental methods is needed for future studies. 2. Application PLGA barrier membrane to periodontal defect demonstrated improved healing in new bone and new cementum. 3. There was a minimal periodontal regeneration with calcium sulfate barrier membrane only. But, there was better healing pattern in combination of calcium sulfate membrane with bone graft material, such as DFDBA. 4. There was no significant difference between the experimental group that used chitosan membrane only and the control group. But, in combination with bone graft material for space maintanence, periodontal regeneration was improved. Overall, Space maintenance is a critical factor for Guided tissue regeneration using barrier membranes. Also, a barrier membrane itself that has difficulty in maintaining space, achieved better result when used with graft material.

Background and Objectives:
Leaflet thrombosis after transcatheter aortic valve replacement (TAVR) has been reported recently, whereas thrombus formation in sinus of Valsalva has yet to be fully evaluated. This study describes clinical and cardiac computed tomography (CT) findings of patients with sinus of Valsalva thrombosis.
Methods:
Between March 2011 and Aug 2019, 192 patients underwent cardiac CT after TAVR. After a retrospective review of CT images, 9 patients (82 years, male:female=2:7) who had sinus of Valsalva thrombosis identified by cardiac CT were selected for this study. Patient demographics, interval between TAVR and cardiac CT scan, location and CT attenuation of sinus of Valsalva thrombosis, and presence of concurrent leaflet thrombosis were evaluated.
Results:
The median interval between TAVR and cardiac CT was 11 days. Sinus of Valsalva thrombosis was frequently detected in the non-coronary sinus (89%, 8/9), and predominantly located in the bottom of the sinus extending upward towards the sinotubular junction. Three patients had concomitant leaflet thrombosis, and 3 patients had subclinical embolic stroke noted on brain magnetic resonance imaging. All patients had been prescribed aspirin and clopidogrel after TAVR for at least 6 months without anticoagulants.
Conclusions
Cardiac CT after TAVR can detect sinus of Valsalva thrombosis, and attention should be paid to this potential source of subsequent systemic embolization.
