In patients with the sequele of poliomyelitis, pyogenic or tuberculous arthritis, or trauma, flexion contracture of the knee could be developed and many difficult problems would be met in treating them. Ilizarov suggested the method of gradual correction of deformities of bone after corticotomy-osteo- clasis, combined with gradual elongation of the shortened soft tissues, and the flexion contracture of knee & limb length discrepancy could be corrected simultaneously or sequentially following a sigle operative procedure. The authors have treated 25 patients with flexion contracture of the knee joint by the principle of Ilizarov treatment at the Sang Gye Paik Hospital between September 1991 and March 1994, The average preoperative flexion contracture of the knee joint, 25° (range, 10°

Purpose: The accessibility of medical facilities for cancer patients affects both their comfort and survival. Patients in rural areas have a higher socioeconomic burden and are more vulnerable to emergency situations than urban dwellers. This study examined the feasibility and effectiveness of a cancer care model integrating a regional cancer center (RCC) and public health center (PHC). Methods: This study analyzed the construction of a safety care network for cancer patients that integrated an RCC and PHC. Two public health institutions (an RCC in Gyeongnam and a PHC in Geochang County) collaborated on the development of the community care model. The study lasted 13 months beginning in February 2019 to February 2020. Results: The RCC developed the protocol for evaluating and measuring 27 cancer-related symptoms, conducted education for PHC nurses, and administered case counseling. The staff at the PHC registered, evaluated, and routinely monitored patients through home visits. A smartphone application and regular video conferences were incorporated to facilitate mutual communication. In total, 177 patients (mean age: 70.9 years; men: 59%) were enrolled from February 2019 to February 2020. Patients’ greatest unmet need was the presence of a nearby cancer treatment hospital (83%). In total, 28 (33%) and 44 (52%) participants answered that the care model was very helpful or helpful, respectively. Conclusion We confirmed that a combined RCC-PHC program for cancer patients in rural areas is feasible and can bring satisfaction to patients as a safety care network. This program could mitigate health inequalities caused by accessibility issues.

A femoral artery aneurysm (FAA) is a rare disease with the symptoms of nerve and vein compression, lower extremity ischemia, local pain, pulsating mass, and rupture. Compression of the femoral vein may cause the symptoms of lower extremity venous insufficiency, which accounts for nearly 10% of FAA patients. (Case) A 55 year-old female was hospitalized, suffering from swelling, heaviness and venous ectasia of the left lower extremity. Preoperative CT angiography revealed a 3 cm-sized FAA and compression of the femoral vein due to the aneurysm in her left inguinal area. The aneurysm extended from the distal external iliac artery (EIA) to both the proximal superficial femoral artery (SFA) and profunda femoris artery (PFA). After an aneurysmectomy, interposition grafting from the EIA to the SFA with reimplantation of PFA was done. Immediately after the operation, the symptoms dramatically disappeared, and the follow-up CT revealed the decompressed femoral vein.

Endobronchial metastasis from extrapulmonary carcinoma, both clinically and radiologically similar in appearance to a primary lung cancer, is rare. We present a case of endobronchial metastasis from parosteal osteosarcoma. The first abnormality noted on the chest radiography was tramline calcification with branching pattern along the right upper lobe bronchus and intermediate bronchus. This lesion progressed into a solid calcified nodule which increased in size. Another lesion with same pattern was also observed in the left lower lung zone.

BACKGROUND: Injury severity scoring systems that quantify and predict trauma outcomes have not been established in Korea. This study was designed to determine the best system for use in the Korean trauma population. METHODS: We collected and analyzed the data from trauma patients admitted to our institution from January 2010 to December 2014. Injury Severity Score (ISS), Revised Trauma Score (RTS), and Trauma and Injury Severity Score (TRISS) were calculated based on the data from the enrolled patients. Area under the receiver operating characteristic (ROC) curve (AUC) for the prediction ability of each scoring system was obtained, and a pairwise comparison of ROC curves was performed. Additionally, the cut-off values were estimated to predict mortality, and the corresponding accuracy, positive predictive value, and negative predictive value were obtained. RESULTS: A total of 7,120 trauma patients (6,668 blunt and 452 penetrating injuries) were enrolled in this study. The AUCs of ISS, RTS, and TRISS were 0.866, 0.894, and 0.942, respectively, and the prediction ability of the TRISS was significantly better than the others (p < 0.001, respectively). The cut-off value of the TRISS was 0.9082, with a sensitivity of 81.9% and specificity of 92.0%; mortality was predicted with an accuracy of 91.2%; its positive predictive value was the highest at 46.8%. CONCLUSIONS: The results of our study were based on the data from one institution and suggest that the TRISS is the best prediction model of trauma outcomes in the current Korean population. Further study is needed with more data from multiple centers in Korea.

The dorsolateral medullary syndrome (Wallenberg's syndrome) is produced by infarction of a wedge of lateral medulla posterior to the inferior olivary nucleus, and is usually caused by vertebral artery occlusion. Ipsilateral axial lateropulsion as an initial symptom of vertebral artery occlusion is rare, and the responsible anatomical structure is still uncertain. Here we describe a patient presenting with ipsilateral axial lateropulsion as an initial symptom of vertebral artery occlusion.

Venous aneurysm of the superior vena cava(SVC) is a rare congenital lesion and can be classified morphologically as either fusiform or saccular. Although there is a controversy with regard to the need for either conservative or surgical treatment, surgery is recommended for the saccular type as major complications of the aneurysm may occur. We report a case of saccular aneurysm of the SVC, treated by means of an endoluminal stent-graft.
