Core decompression is still widely used in avascular necrosis of the femoral head but the results are unpredictable and the indications are not settled yet. The reparative process of the decompressed femoral head is poorly understood. Seven cases in 5 patients were undertaken THRA following failed decompression and these were studied for the radiological and pathological changes of the core tracts. The lesions of failed cases were involved more than 1/3 of femoral head on MRI and all cases were stage II A or B. The extent of the necrotic area in MRI was enlarged with crack, sclerosis and sometimes gas collection. Depression of the subchondral plates were also observed. Capillary ingrowth or neovascularization was not found at all and there were only fibrosis, inflammatory response and foreign body reactions.

Journal of Korean Academy of Nursing 2022;52(2):121-133
Purpose:
This study examined the impact of a virtual reality intervention program based on psychological needs on behavioral and psychological symptoms, apathy, and quality of life (QOL) in patients with dementia or mild cognitive impairment living in nursing facilities.
Methods:
This study is nonequivalent control group pretest-posttest design of quasi-experimental study. The study collected data from November 18, 2020 to July 24, 2021 from patients with dementia or mild cognitive impairment (30 in the experimental group and 30 in the control group) at three nursing facilities in G city using self-reporting and caregiver-informant reporting methods. The analysis employed the chi-square test, Fisher’s exact test, paired t-test, independent t-test, Wilcoxon signed rank test, Mann–Whitney U, repeated measures ANOVA, GEE, using SPSS/WIN 27.0.
Results:
The severity of behavioral and psychological symptoms (Wald χ2 = 2.68, p = .102) and the care burden of caregivers (Wald χ2 = 1.72, p = .190) were not significant and was no significant time and group interaction effect (Wald χ2 = 0.63, p = .426, Wald χ2 = 0.52, p =. 471). The difference in apathy and QOL score were statistically significant for the group-time interaction (F = 43.65, p < .001; F = 4.35, p= .041).
Conclusion
The virtual reality intervention program of this study shows a positive effect on the apathy reduction and QOL of patients with dementia or mild cognitive impairment residing in nursing facilities.
5.Three-Dimensional Image and Virtual Dissection Program of the BronchopulmonarY Segments Made of Korean Cadaver: Three-dimensional image of bronchopulmonary segments.

Three-dimensional (3D) structure of the bronchopulmonary segments should be understood for accurate diagnosis and treatment of lung diseases. Two-dimensional (2D) tools (e.g. anatomy books) or traditional 3D tools (e.g. plastic models) are not sufficient for understanding 3D structure of the bronchopulmonary segments. The lung of a cadaver may not always be available for dissection, when it is needed. To overcome this problem, virtual dissection programs of the lung have been made. However, most programs include either 2D images that do not permit free dissection or radiographs that do not reveal true color and have limited resolution, and cannot represent 3D structure of the bronchopulmonary segments. Moreover, it is necessary to make a virtual dissection program of each race and ethnic group. Thus, we attempted to make a 3D image and virtual dissection program of the lung using a Korean cadaver in order to help medical students and doctors better understand 3D structure of the bronchopulmonary segments. One pair of lungs was extracted from a Korean male cadaver. Dye with specific color was injected into each segmental bronchus to distinguish bronchopulmonary segments. The lungs were embedded with gelatin solution, and serially-sectioned with 1 mm- thickness using a meat slicer. Sectioned specimens from each lung were inputted into the computer using a scanner (300 X 400 resolution, true color). 2D images of the lungs were aligned on the alignment program which was composed using IDL language. In 2D images, the bronchopulmonary segments were manually segmented by help of dye. 3D images of the bronchopulmonary segments were reconstructed through the volume-based rendering of 2D images. With 3D images as the main features, the virtual dissection program of the bronchopulmonary segments was composed using IDL language. Various virtual dissection functions, such as sectioning a lung at free angles to show its plane, identifying the bronchopulmonary segments represented in the sectioned plane, and rotating the selected bronchopulmonary segments at free angles, were established. This virtual dissection program of the bronchopulmonary segments is helpful in better understanding 3D location and shape of the bronchopulmonary segments; it is expected to be used through CD-title or Internet as an educational tool for medical students and doctors.

A 71-year-old woman presented with an enlarging mass in the right buttock, with pain and tingling sensation in sitting position. Five years ago, she was diagnosed with acute limb ischemia due to acute thrombosis of right persistent sciatic artery (PSA), and she underwent successful thromboembolectomy and femoro-tibioperoneal trunk bypass. Computed tomography angiography revealed a huge PSA aneurysm (PSAA). During the previous bypass, the distal popliteal artery was ligated just above the distal anastomosis to exclude the PSAA, whose proximal end was already thrombosed. However, PSAA has grown to cause compression symptoms, and the mechanism of aneurysm growth can be ascribed to type 1a or type 2 endoleak. In order to relieve the compression symptoms, aneurysm excision was performed without any injury to the sciatic nerve. A postoperative tingling sensation due to sciatic-nerve stimulation in the supine position resolved spontaneously one month after surgery.

In patients with dermatomyositis, chronic inflammation of the pharynx and esophagus results in coughing and difficulty in swallowing. These become important clinical symptoms, especially if they contribute to malnutrition or aspiration pneumonia. They can ultimately reduce the quality of life. In rare cases, if the symptoms worsen despite proper treatment, serious complications may arise, a reason to suspect an esophageal perforation or abscess. The authors report a case of dermatomyositis in an adult patient with rare complications of spontaneous esophageal perforation and hypopharyngeal abscess. The patient received non-surgical treatment and was able to resume oral intake of food.
