Purpose: This study investigated the rate of retear and related factors after arthroscopic repair of rotator cuff tears involving more than one tendon. Materials & Methods: Arthroscopic repair of 22 rotator cuff tears (average size 3.2cm: average age 58 years old) involving the supraspinatus and part or all of the infraspinatus were investigated using MRI on average 10 months after repair. The status of the repaired cuff was investigated using Sugaya's classification, and the change in muscle was evaluated with Goutallier's classification. Results: Retear (Sugaya grade IV, V) was found in 7cases(32%). Tears larger than 3cm had a higher retear rate(67%) than smaller tears(8%). Retear cases had Goutallier grade II or higher muscle changes preoperatively and showed aggravation of muscle atrophy postoperatively. Even without retear, reversal of muscle change was not seen Conclusion: Rotator cuff tears not confined to the supraspinatus had a 32% retear rate after arthroscopic repair. The size of the tear was the most crucial factor influencing retear. Retear was frequent in tear over 3cm. Atrophy of the cuff muscle worsened when the repair failed but did not improve even without retear.

Research of thyroid cancer, liver cancer, and lung cancer has been reported in Korea. However microRNA research of multiple myeloma has never been reported. Hence we intended to confirm whether microRNA can be utilized as a diagnostic marker to patients of multiple myeloma. We also intended to evaluate whether microRNA can be detected in paraffin-embedded tissue (FFPE). This research was conducted targeting 8 samples from patients of multiple myeloma who do not have any other diseases, and 2 control samples. From January 2010 to July 2012, we selected miR-15a, miR-16, miR-21, miR-181a and miR-221 as microRNA target genes. It was decided that for a sample to be significant, the results should show values more than 1.5 or less than -1.5. Our findings of fold change were highly significant in miR-15a with a value of 37.5% (3/8). From these studies, we learned that miR-15a is useful with westerners. miR-221, on the other hand, shows conflicts with westerners, so more research will be needed in this area. In addition, it was confirmed that microRNA can be detected in paraffin embedded tissue (FFPE).

Multiple external carotid artery aneurysms with neurofibromatosis are rare. Trauma is the primary cause in the development of aneurysms of the external carotid artery. A 39-year-old female patient was referred to the emergency room because of a headache and a huge lump over the left temporo-parieto-occipital region. The physical examination revealed a huge round mass, $5{\times}15{\times}18cm$, in the left temporo-parieto-occipital region and low set left ear and multiple caf au lait spots in trunk and extremities. The external carotid artery angiography demonstrated multiple aneurysms arising from the superficial temporal artery and occipital artery. A MRI showed a huge hematoma on temporo-parieto-occipital region and postauricular mass suggested of subcutaneous neurofibroma. Embolization followed by surgical resections of those aneurysms and neighboring mass were performed and good result was obtained. We report our case with review of literature.

Purpose: The purpose of this study is to evaluate the usefulness of anatomical single bundle anterior cruciate ligament (ACL) reconstruction using outside-in technique by clinical outcome analysis. Materials and Methods: From July 2009 to July 2010, 41 cases of single bundle ACL reconstruction using outside-in technique which were followed minimum 1 year were enrolled. Clinical results were evaluated using International Knee Documentation Committee (IKDC) subjective knee evaluation score, Lysholm score, pivot shift test, one leg hop test, KT-1000 arthrometer test, Telos stress arthrometer test. Results: IKDC subjective knee score and Lysholm score were improved to $86.1{\pm}2.1$ and $91.2{\pm}3.8$ postoperatively (p<0.0001 and p<0.0001, respectively). KT-1000 arthrometer test and Telos stress arthrometer test also were improved to $2.2{\pm}0.9\;mm$ and $2.3{\pm}1.2\;mm$ (p<0.0001 and p<0.0001, respectively). Pivot shift test and one leg hop test revealed good results. Conclusion: Anatomical single bundle anterior cruciate ligament reconstruction using outside-in technique showed good clinical results, so it was considered available method.

Purpose: To evaluate the outcome of the two-bundle anterior cruciate ligament reconstruction with single femoral tunnel and tibialis anterior tendon allograft and to determine any functional advantages. Materials and Methods: From June 2006 to March 2008, we performed single femoral tunnel and two-bundle ACL reconstruction with tibialis anterior tendon allograft in 26 cases. Mean age was 35.5 years. 20 cases were male and 6 cases were female. Average follow-up period was 2 years and 5 months, range from 1 year to 3 years and 5 months. Subjective and objective parameters were utilized in analyses, such as the mean range of motion, Lysholm knee score, Tegner activity score, Lachman test and IKDC score. Results: Postoperative mean Lysholm knee score, IKDC Evaluation Form, Tegner activity scale, Pivot shift test, and anterior displacement by the Telos stress test demonstrated statistically significant differences compared to the preoperative. Conclusion: Two-bundle anterior cruciate ligament reconstruction with single femoral tunnel showed good clinical results and was good operative technique.

In the fracture operation of pan facial fracture, there are many cases where the shape and position of the occlusal and oral structures are abnormally changed because the index for repositioning to the original position is insufficient. And trismus and gag reflex in patients with pan facial fractures increase the difficulty of dental treatment, and the difference in the position of the jaw bone makes it difficult to restore aesthetically and functionally. In this case, digital workflows for minimal intraoral work could be selected to reduce patient discomfort and the difficulty of dental treatment. This case is using a digital workflow from implant planning to final prosthesis production in a patient with acquired skeletal grade III, trismus, and gag reflex due to pan facial fracture 15 years ago. In this case report, the use of digital workflow in a patient who has difficulty in dental treatment was able to minimize patient discomfort and obtain esthetic and functionally appropriate results.

원격 전이된 비인두암 환자에서 주요한 치료 방법은 고식적 항암화학치료에 국한되어왔다. 그러나 적극적인 항암화학치료로 비인두암 환자 중 많은 환자에서 치료 반응을 보이며, 치료 반응을 보인 환자군에서는 국소 제어가 중요한 문제가 된다. 본 저자들은 원격 전이 된 환자 1예를 보고하고자 한다. 환자는 큰 크기의 다발성 전이가 있었으나 항암화학요법으로 관해 상태를 보였다. 이후 공고화 항암화학방사선요법을 추가하였고 현재 30개월 간 무병상태이다. 원격전이된 비인두암에서 공고화 항암화학방사선 요법의 역할에 대하여 문헌 고찰을 통해 논의하고자 한다.

금년 겨울은 유난히 눈이 많고 추운 것으로 기록되고 있다. 서해안과 전북 지방의 기록적인 폭설과 연일 지속되는 강추위로 정읍, 고창 지역의 양계 농장에 많은 피해가 발생했다. 이처럼 추위와 눈이 많은 겨울철에는 대부분의 농장에서 겪게 되는 것이 호흡기 질병이다. 호흡기 질병이야 일년 열두달 닭을 사육하면 농장에서 끊이지 않는 고질적인 질병이지만 겨울철에는 보온 문제로 인해 환기의 제한을 받다 보니 그 피해가 더욱 심해지고 있다. 따라서 겨울철 계사내 가스 증가와 이로 인한 호흡기성 질병의 증가는 생산성을 저해하는 중요한 요인이 되고 있다. 본고에서는 겨울철에 다발하는 호흡기 질병에 대해 간략히 소개하고자 한다.
