Two cases of pseudoxanthoma elasticum associated with angioid streaks in both eyes were presented and the literatures were reviewed. The affected sisters were 15 and 18 years female among the five siblings. They had pin head sized yellowish maculopapular eruptions on the sides of the neck and axillae, and also visual distubance of the both eyes. They seemed to be autosomal recessive inberitance in their family background. There were no other complications.

A wide variety of malignancies, including carcinoma of the lung, breast, prostate thyroid and kidney, frequently metastasize to bone. Patient suffering pathological fracture secondary to these metastases are frequently referred to the orthopaedic surgeon for care and management. In such cases, operative intervention with rigid fixation and early ambulation offer much in terms of over-all patient management. One case of breast careinoma metastatic to right proximal femur, neck and femoral head of segmental resection and restoration by special segmental femoral prosthesis with Giliberty Bipolar Endoprosthesis was presented. This technique provides an effective means of restoring the structural integrity of proximal femur and of preserving physiologic function of the joint.

For many years, developmental and physiological differences have been known to exist between anatomic segments of the colorectum. Because of different outcomes, prognoses, and clinical responses to chemotherapy, the distinction between right colon cancer (RCC) and left colon cancer (LCC) has gained attention. Furthermore, variations in the molecular features and gut microbiota between right and LCCs have recently been a hot research topic. CpG island methylator phenotype-high, microsatellite instability-high colorectal cancers are more likely to occur on the right side whereas tumors with chromosomal instability have been detected in approximately 75% of LCC patients and 30% of RCC patients. The mutation rates of oncogenes and tumor suppressor genes also differ between RCC and LCC patients. Biofilm is more abundant in RCC patients than LLC patients, as are Prevotella, Selenomonas, and Peptostreptococcus. Conversely, Fusobacterium, Escherichia/Shigella, and Leptotrichia are more abundant in LCC patients compared to RCC patients. Distinctive characteristics are apparent in terms of molecular features and gut microbiota between right and LCC. However, how or to what extent these differences influence diverging oncologic outcomes remains unclear. Further clinical and translational studies are needed to elucidate the causative relationship between primary tumor location and prognosis.

For orthodontic tooth movement, optimal orthodontic force should be maintained without periodontal breakdown and alveolar bone should be remodeled physiologically. Therefore, To obtain proper occlusion through tooth movement within alveolar bone, we should know the biomechanics of teeth and supporting tissues. The present study was performed to observe histologic changes of periodontal tissue immediately after application of orthodontic force and during the retention period in growing young adult dogs. In this study, experimental group contained between mandibular left canie and 1st molar and control group contained contralateral teeth of same animal. The .018"x.22" stainless steel closed coil spring(Dentaurum Co.) was ligated on the experimental teeth at initial 200gm-force from mandibular canine to 1st molar. The animals(4 to 6 months aged young adult dogs) were sacrificed on 0, 14, 28 days after the finish of appliance activation, and then tissue samples were divided into hematoxylin-eosin(HE) staining section, ground section, alkaline phosphatase(ALP) staining section, and tartrate-resistant acid phosphatase(TRAP) staining section. Thereafter, the preparations were examined under light microsopy. The following results were obtained: 1. Immediately after the finish of appliance activation, the periodontal space was increased in tension side, but decreased in pressure side compared to that of control. The hyalinized zone was also observed in the periodontium. 2. After the 14-day retention, periodontal space was decreased in tension side and slightly increased in pressure side compared to that of immediately after the finish of appliance activation. The hyalinized zone was repaired and a few osteoblasts showing slightly new bone formation were seen. Osteoblasts were scarcely observed along the alveolar bone. 3. After the 28-day retention, the periodontal fibers are normally repaired. A lot of TRAP(+) osteoclasts and increased alveolar bone resorption were observed in pressure side, and AP(+) osteoblast and increased new bone formation were observed in tension side.

Purpose: This study aimed to explore how autonomy support mediates the association between exercise knowledge and exercise self-efficacy in patients with severe mental illness. Methods: A total of 181 individuals were selected through convenience sampling. They completed self-administered surveys measuring exercise knowledge, autonomy support, and exercise self-efficacy. The data analysis was conducted using descriptive statistics, t-tests, one-way analysis of variance, Pearson’s correlation coefficients, and multiple linear regression. To determine the statistical significance of the mediating effect, a bootstrapping test was also conducted. Results: This research revealed that autonomy support significantly predicted exercise self-efficacy and partially mediated the association between exercise knowledge and exercise self-efficacy (lower limit confidence interval [LLCI]: 2.34; upper limit confidence interval [ULCI]: 5.97). The model incorporating exercise knowledge and autonomy support explained 42.0% of the variance in exercise self-efficacy. Conclusion Collaborative endeavors involving mental health practitioners and exercise experts demonstrate notable efficacy in enhancing exercise self-efficacy of individuals with mental illness.

PURPOSE: To survive in an ecological environment, an individual must develop immunity to various antigens. Therefore, populations of peripheral blood mononuclear cells (PBMC) in humans change continuously with growth. The object of this study is to evaluate the apoptosis of peripheral blood mononuclear cells (PBMC) in normal children of different ages. METHODS: PBMC were isolated from the study groups. Ten cord blood samples of normal babies, 10 blood samples of normal children each from 4 different age groups (0-1, 2-5, 6-10, 11-15 year- old and adult), and 20 from normal adults were included in this study. After 24 and 48 hrs incubation in RPMI1640 media containing 10% fetal calf serum, cells were stained with Annexin V and PI and then analyzed with FACScan flowcytometer. RESULTS: Cord blood mononuclear cells showed the lowest percentage of apoptosis compared to other age groups. PBMC isolated from the 0-1 year-old normal children showed the highest percentage of apoptosis, and the percentage of apoptosis decreased with increase of age. After the age of 10, the percentage of PBMC apoptosis was the same as that of adults. CONCLUSION: The differences in the percentage of PBMC apoptosis with different age groups might be from immunologically different state of the hosts with different age. This result could be a useful reference data for the study of apoptosis in pediatric disease in the future.
