현행 행정검시제도는 몇 가지 문제점을 갖고 있다. 행정검시권자는 자치단체장이지만 실제로는 대부분 형사소송법상 변사체로 처리되어 검사의 지휘로 사법검시가 이루어지고 있다. 또한 검시대상이 분명하게 규정되어 있지 않아 제대로 죽음의 원인이 밝혀지지 않는 이른바 의문사의 문제도 사회적인 현안으로 자리하고 있다. 이 논문에서는 행정검시제도 개선방안으로 첫째 검시에 관한 통일적인 법률체계의 정비가 필요하며 둘째 검시대상을 명확히 함으로써 법의관은 법률에 규정된 사체에 대한 검시책임을 지며, 그 결과 범죄가능성이 있는 경우 수사기관에 통보할 의무를 부여하고, 셋째 수사기관도 검시가 필요한 사체에 대해 법의관에게 검시를 요구해야 한다. 넷째, 사망원인 조사에 전문성이 부족하면 정확성이 떨어지므로 의학적 전문지식이 있는 법의병리전문의 또는 법의관이 검시의 주체가 되어야 할 것이다. 이 논문에서는 우리나라의 행정검시제도의 한계와 문제를 극복하기 위해서 행정검시 개선방안을 소개했다.

Aspergillus infection is the most common cause of death due to fungi in immunocompromised hosts. Aspergillus tracheobronchitis is an uncommon but severe form of invasive pulmonary aspergillosis, which is limited entirely or mainly to the tracheobronchial tree and can often be life-threatening. We report a case of a 54-year-old man who died from Aspergillus tracheobronchitis without an underlying disease. Autopsy revealed an extensive yellowish plaque adhering to the trachea and bronchial wall. The microscopic examination of the trachea and bronchus revealed septate branching hyphae of Aspergillus.

Ehlers-Danlos syndrome type IV (EDS IV) is a hereditary disorder of the connective tissue, characterized by easy bruising, thin skin with visible veins, and spontaneous rupture of the large arteries, uterus, or bowel. EDS IV is caused by mutations of the gene for type III procollagen (COL3A1), resulting in insufficient collagen production or a defect in the structure of collagen. EDS IV can have fatal complications such as the rupture of great vessels or organs, which can cause hemorrhaging and sudden unexpected death. Here, we report a case of a 43-year-old female who collapsed after a struggle with a neighbor. In this patient, the bifurcation of the bilateral common iliac artery ruptured, with no evidence of trauma, inflammation, or atherosclerosis. Genetic analysis of COL3A1 showed the presence of a c.2771G>A (p.Gly924Arg) mutation, which may be associated with EDS IV. The forensic pathologist should consider the possibility that the spontaneous visceral or arterial rupture was caused by EDS IV. Genetic analysis is not currently a routine procedure during autopsy. However, in this case, we suggest that the patient possibly had an underlying EDS IV condition, and we recommended family members of the deceased to seek genetic analysis and counseling.

There have been many radiographic studies on age estimation that evaluate reduction in size of dental pulp cavity with secondary dentin formation. The Paewinsky method reported high accuracy in estimating ages by measuring the width of the pulp cavity in panoramic radiographs. The aim of this study was to evaluate the application of the Paewinsky method to digital periapical radiographs. This study was conducted on 103 cases that reported to the Section of Human Identification of the National Forensic Service. The age was calculated by applying the Paewinsky method that measures the root and pulp canal width at three points in a tooth. The estimation results were compared with those calculated by the Johanson method. When the Paewinsky models were applied to digital periapical radiographs, the errors were significantly greater as compared to the original study. The errors of the maxillary second premolar and mandibular lateral incisor were greater than those of the maxillary central incisor, lateral incisor, mandibular canine, and first premolar. Furthermore, errors of the age estimation models in level C were greater than those in levels A and B. This study could be a reference for the application of the Paewinsky method to digital periapical radiographs.

Objective: To quantify the effects of midline-related landmark identification on midline deviation measurements in posteroanterior (PA) cephalograms using a cascaded convolutional neural network (CNN). Methods: A total of 2,903 PA cephalogram images obtained from 9 university hospitals were divided into training, internal validation, and test sets (n = 2,150, 376, and 377). As the gold standard, 2 orthodontic professors marked the bilateral landmarks, including the frontozygomatic suture point and latero-orbitale (LO), and the midline landmarks, including the crista galli, anterior nasal spine (ANS), upper dental midpoint (UDM), lower dental midpoint (LDM), and menton (Me). For the test, Examiner-1 and Examiner-2 (3-year and 1-year orthodontic residents) and the Cascaded-CNN models marked the landmarks. After point-to-point errors of landmark identification, the successful detection rate (SDR) and distance and direction of the midline landmark deviation from the midsagittal line (ANS-mid, UDM-mid, LDM-mid, and Me-mid) were measured, and statistical analysis was performed. Results: The cascaded-CNN algorithm showed a clinically acceptable level of point-to-point error (1.26 mm vs. 1.57 mm in Examiner-1 and 1.75 mm in Examiner-2). The average SDR within the 2 mm range was 83.2%, with high accuracy at the LO (right, 96.9%; left, 97.1%), and UDM (96.9%). The absolute measurement errors were less than 1 mm for ANS-mid, UDM-mid, and LDM-mid compared with the gold standard. Conclusions: The cascaded-CNN model may be considered an effective tool for the auto-identification of midline landmarks and quantification of midline deviation in PA cephalograms of adult patients, regardless of variations in the image acquisition method.

목적: 근시안에서 암순응상태의 동공크기를 측정하여 분석해 보고 이에 영향을 주는 요인에 대해 알아보고자 하였다. 방법: 안과적 질환이 없는 근시안 191명(191안)을 대상으로 암순응상태에서 동공측정계(Colvard pupillometer, OASIS medical, USA)를 사용하여 동공의 크기를 측정하였고 연령, 각막크기, 등가구면 굴절이상도, 각막곡률값과 비교분석하였다. 또한, 동공측정계의 재현성을 알아보기 위해 검사자내(intra-examiner) 및 검사자간(inter-examiner)에서의 측정값을 비교하였다. 결과: 암순응상태에서의 평균동공크기는 $6.64{\pm}0.68$ mm(5.00~8.00 mm)였고, 연령이 낮고 각막크기가 클수록 동공크기는 커지는 경향을 보였고 등가구면 굴절이상도가 낮고 각막곡률이 가파를수록 동공크기가 작아지는 경향을 보였다. 동공측정계의 검사자내 및 검사자간에서의 재현성은 매우 높은 것으로 나타났다(Guttman split-half point>0.91). 결론: 암순응상태에서의 동공크기는 연령, 각막크기, 등가구면 굴절이상도, 각막곡률과 관련 있었으며, RGP 콘택트렌즈나 백내장 수술, 굴절교정수술 등에서 발생할 수 있는 불편함을 예방하는데 참고할 수 있을 것으로 생각된다.

The Pediatric Balance Scale (PBS) is a modified Berg's Balance Scale developed as a balance measure for school-aged children with mild to moderate motor impairments. The purpose of this study was to determine the inter-examiner reliability of the Korean version of PBS when applied to children with developmental delays. In this study, PBS was administrated to a total of 79 children with developmental delays (17 with global developmental delay, 31 with cerebral palsy, and 31 with mental retardation) in the Seoul Community Rehabilitation Center. Two pediatric trained physical therapists with longer than 13 year of clinical experience scored the children's performance blind, while replaying videotaped data. The inter-examiner reliability was statistically determined by intraclass correlation coefficients (ICCs). The results of this study revealed that the Korean version of PBS seems to have high inter-examiner reliability when applied to children with movement disorders such as global developmental delay (ICC=.96) and cerebral palsy (ICC=.97); however, it has relatively lower inter-examiner reliability (ICC=.78) for children with developmental delay secondary to mental retardation. therefore, the results support that the Korean version of the PBS could be a useful clinical measurement to assess the balance skills for children with developmental delay who have an adequate level of cognition to enable them to fol1ow the verbal instructions to complete the test.

Objective : Computed tomography (CT)-based method of three dimensional (3D) analysis ($MIMICS^{(R)}$, Materialise, Leuven, Belgium) is reported as very useful software for evaluation of OPLL, but its reliability and reproducibility are obscure. This study was conducted to evaluate the accuracy of $MIMICS^{(R)}$ system, and inter- and intra-observer reliability in the measurement of OPLL. Methods : Three neurosurgeons independently analyzed the randomly selected 10 OPLL cases with medical image processing software ($MIMICS^{(R)}$) which create 3D model with Digital Imaging and Communication in Medicine (DICOM) data from CT images after brief explanation was given to examiners before the image construction steps. To assess the reliability of inter- and intra-examiner intraclass correlation coefficient (ICC), 3 examiners measured 4 parameters (volume, length, width, and length) in 10 cases 2 times with 1-week interval. Results : The inter-examiner ICCs among 3 examiners were 0.996 (95% confidence interval [CI], 0.987-0.999) for volume measurement, 0.973 (95% CI, 0.907-0.978) for thickness, 0.969 (95% CI, 0.895-0.993) for width, and 0.995 (95% CI, 0.983-0.999) for length. The intra-examiner ICCs were 0.994 (range, 0.991-0.996) for volume, 0.996 (range, 0.944-0.998) for length, 0.930 (range, 0.873-0.947) for width, and 0.987 (range, 0.985-0.995) for length. Conclusion : The medical image processing software ($MIMICS^{(R)}$) provided detailed quantification OPLL volume with minimal error of inter- and intra-observer reliability in the measurement of OPLL.

척수경막동정맥루의 수술적기법은 동정맥루에 결찰을 통해 혈액공급을 원활하게 하여 신경학적 손상을 막는 수술법이다. 이에 INM 검사는 환자의 신경학적 증상에 따른 수술 후의 부작용을 최소화하기 위해 복합(multimodal)적인 신경계검사가 요구된다. TceMEP는 환자의 피질척수로(corticospinal tract)의 상태를 확인할 수 있는 검사이다. 척수경막동정맥루에서 결찰할 때마다 TceMEP를 분단위로 검사를 진행해 이상 유무를 확인해야 한다. 하지만 검사자가 수술과정이나 검사에 대한 술기가 부족하거나 검사자와 집도의 간에 원활하지 못한 의사소통으로 TceMEP의 잘못된 자극 시점은 수술진행에 방해가 되며 수술 후 환자에게 마비와 위약과 같은 부작용이 생길 수 있다. 척수경막동정맥루 결찰술에서 INM은 앞으로 더 많은 연구와 함께 추가적인 증례보고들이 필요할 것이라고 생각하며 검사자들 또한 환자의 신경학적 손상을 최소화하기 위해 노력해야 할 것이다.

Recently, the incidence of anterior cruciate ligament injury is rapidly increasing because many young Korean are actively participating in sports activities including basketball, skiing and soccer. Sometimes acute ACL injuries arc misdiagnosed as sprain because of pain and muscle spasm. An accurate physical examination and careful history taking are very important to diagnose the ACL injuries. Therefore author described the skill of history taking and the technique of physical examination to diagnose ACL injuries. The most sensitive test is the Lachman's test, which is performed with the knee in 200 of flexion, the femur stabilized with full flexed examiner's knee placed behind patient's distal thigh and one hand of examiner, and the proximal tibia grasped with the other. The pivot shift test is a passive motion test that attempts to subluxate the tibia anteriorly, then have it reduce rapidly. The pivot shift test is very sensitive test to diagnose the chronic ACL injuries.
