Purpose: This study reviewed what the location of death (LOD) means as an outcome and how to use LOD to assess end-of-life (EOL) care. This study also examined the reason why LOD is significant for the quality of EOL care. Methods: A literature review was performed, using LODs and home deaths as outcomes in the field of EOL care, and analyzed the findings associated with key fields in regards to LOD. Results: Palliative care research used LOD, in particular, hospital death (versus home death) as a significant outcome when examining cost savings, quality of life care, and patient and family preferences. Based on substantial evidence from previous research, home hospice or continuous palliative care in non-hospital settings (i.e. homes, nursing homes) have been designed and available for dying patients in developed countries. Conclusion: The LOD delivers practical significance as an outcome for diverse reasons. In-depth examination on LOD in South Korea is needed despite limitations to interpretation of its meaning in the country.

Vertex epidural hematoma (VEH) is an uncommon presentation of all epidural hematomas and presents with a wide range of symptom and signs. Diagnosis as well as treatment of VEH is also difficult because of its location adjacent to superior sagittal sinus (SSS). A 43-year-old male visited our hospital after fall down and was diagnosed with VEH. While evaluating its location and patency of SSS, he was deteriorated and urgently underwent evacuation of VEH. Bilateral craniotomies on each side, leaving a central bony island to avoid bleeding of midline structure and provide an anchor for dural tack-ups. After the operation, VEH was totally removed and the patient has restored.

Image-guided surgery (IGS) system has become well known in the field of neurosurgery and spine surgery. A patient's anatomy is first registered to preoperatively acquired CT/ MRI data using the point matching algorithm. A magnetic field digitizer was used to measure the physical space data and the system was based on Workstation of Unix system. To evaluate the spatial accuracy of interactive IGS system, the phantom consisting of rods varied height and known location was used. The RMS error value between CT/MR images and real location was 3-4mm. For the more convenience of the surgery, we provide various image display modules.

The abducens nerve paresis generally can aid in the presumptive diagnosis of abducens schwannoma along with the typical radiological features of schwannomas. The authors present a case of a 76-year-old male patient with a abducens schwannoma without abducens nerve paresis. Peroperatively, abducens nerve located in the cerebellopontine cistern had normal in contour and diameter, despite the mass originated from this nerve. We hypothesize that anatomic location of abducens nerve may affect the vector of tumor growth to prevent destruction of its origin, the abducens nerve.

The purpose of this study is to investigate the relationship between occurrence and inducing factors of herpes labialis developed after periodontal therapy and to suggest prediction model of this lesion. A total of 100 patients were studied. A standard schedule was used for interviews of patients. It included demographic information, patient and familial history of recurrent aphthous ulcer and recurrent herpes labialis, history of systemic disease, religion, and emotional state. In case of female patients, the association of dysmenorrhea and onset of recurrent herpes labialis was also observed. After periodontal therapy, some details about therapy, such as the kind of therapy, location, spending time were recorded. At next appointment, the appearance and location of herpes labialis were examined. The frequency of herpes labialis after periodontal therapy was 8% and the location was predominantly mouth angle. The significant relationship was found between the onset of herpes labialis and the history of recurrent herpes labialis, surgical therapy rather than non-surgical therapy, and spending time. The prediction model of herpes labialis was not apparently established with the results of this study. In conclusion it is suggested that we should minimize traumatic manipulation and treatment time to prevent the onset of herpes labialis after periodontal therapy.

A cystic compound odontoma in the maxillary sinus occurred in a 13-year-old boy. who had missing right upper third molar without having the history of extraction of the wisdom tooth. He complained nasal stuffiness. headache. and pain on the affected face. resembling any sign and symptoms of the maxillary sinus problems. The cystic compound. sized 2 x 1.5 cm in diameter was pedunculated and attached on the posterior wall of the right maxillary sinus and above the antral floor. The location of the compound odontoma in the maxillary sinus was confirmed after panoramic. waters. spiral tomographic. CT examinations and surgical exploration. Its location was on the medial. posterior. superior to the normal position of the maxillary third molar or the maxillary dental arch. The cystic odontoma in the maxillary sinus made the patient have the signs and symptoms of maxillary sinusitis. The cystic compound odontoma might be originated from the dental lamina of the missing upper right third molar. The 'V principle' of the upper jaw growth and the pneumatization process of the maxillary sinus could explain why the compound odontoma had peduncular shape and the location of odontoma was on the medial. superior to the normal position of the maxillary dental arch.

퇴원계획은 환자의 거주지를 고려하여 재활중에 계획되어야한다. 본 연구는 퇴원 1개월 후 재활환자를 대상으로 퇴원장소에 따른 인구통계학적 요인과 재활기능을 비교하는 것을 목적으로 연구가 시행되었다. 대상자는 재활퇴원환자였으며 전체 300명중 146명은 자택으로 154명은 요양원등 시설로 퇴원하였다. 그 결과 수정된 Barthel Index를 이용해 점수화된 재활기능점수가 퇴원장소에 따라 차이가 있는 것으로 나타났다. 즉 자택으로 퇴원한 환자의 재활기능점수가 시설퇴원환자보다 높은 점수를 보였다. 그러나 재택환자의 신체기능과 일상생활 동작이 재활이 필요한 점수를 보였다. 재활환자를 위한 가정 및 시설 방문재활프로그램에 대한 차별화된 전략이 필요하다.

본 논문에서는 동일 환자에 대해 시간차를 두고 촬영한 뇌 CT-CT 혈관조영영상간 움직임을 보정하기 위한 강인하고 고속의 정합방법을 제안한다. 먼저, 두 영상에서 3차원 경계검출 기법을 이용하여 특징점을 추출하고, 기준영상에서는 이를 지역적 가중치 3차원 거리맵으로 변환한다. 부유영상을 기준영상으로 강체변환하면서 두 경계간의 상관관계가 최대인 위치를 탐색한다. 이 때, 최대위치가 더 이상 변화하지 않고 일정 이상 반복되면 해당위치를 최적위치로 하여 부유영상을 최적위치로 변환시켜 두 영상을 정합한다. 실험을 위하여 인공영상을 사용하여 정화성과 강인성을 평가하였고, 육안평가를 위하여 뇌 CT-CT 혈관조영영상을 사용하였다. 본 제안방법은 지역적 가중치 3차원 거리맵을 이용함으로써 적은 샘플링 개수에도 국부최대인 위치에 수렴하지 않고 최적위치로 강인하면서 고속으로 영상이 정합되었다

유-헬스케어(U-Healthcare)에서 이동 환자 상태에 대한 모니터링 기술은 필수적이다. 모니터링 기술에서는 이동 환자의 생체 정보가 동적 위치 정보와 함께 정해진 목적지 서버로 전송되어야 하는데 모니터링할 환자의 수가 증가하며 각 환자의 이동성이 불규칙함에 따라 적절한 부하균형 단계가 중간에 필요해진다. 토르소(Torus) 구조를 기반으로 한 이동 환자 상시 모니터링 시스템에서는 이를 반영하여 먼저 환자 생체 정보를 중간노드로 전송한 후 부하균형 기반의 우선순위 정책에 따라 목적지 서버로 연이어 전송된다. 본 논문에서는 계층적이며 객체지향적인 정형화 명세를 기반으로 하는 시스템 명세 기법을 사용하여 이러한 이동 환자 상시 모니터링 시스템의 전체 구조와 구성 노드들의 결합 관계를 정의한 후 각 요소의 기능을 유사코드로 설계함으로써 본 시스템이 효과적인 환자 정보 수집과 전송, 분배 및 판단에 효율적임을 시스템 명세 기법을 통하여 검증한다.

Background: We analyzed association between viewing two-dimensional computed tomography (2D CT) images in addition to radiographs with radial head treatment recommendations after accounting for patient and surgeon factors in a survey-based experiment. Methods: One hundred and fifty-four surgeons reviewed 15 patient scenarios with terrible triad fracture dislocations of the elbow. Surgeons were randomized to view either radiographs only or radiographs and 2D CT images. The scenarios randomized patient age, hand dominance, and occupation. For each scenario, surgeons were asked if they would recommend fixation or arthroplasty of the radial head. Multi-level logistic regression analysis identified variables associated with radial head treatment recommendations. Results: Reviewing 2D CT images in addition to radiographs had no statistical association with treatment recommendations. A higher likelihood of recommending prosthetic arthroplasty was associated with older patient age, patient occupation not requiring manual labor, surgeon practice location in the United States, practicing for five years or less, and the subspecialties "trauma" and "shoulder and elbow." Conclusions: The results of this study suggest that in terrible triad injuries, the imaging appearance of radial head fractures has no measurable influence on treatment recommendations. Personal surgeon factors and patient demographic characteristics may have a larger role in surgical decision making. Level of evidence: Level III, therapeutic case-control study.
