Fibrous hamartomas of infancy(FHI) are rare, benign, fibroproliferative tumors which usually present in the first 2 years of life. They arise from the subcutanous tissue and usually appear as a single tumor in the axilla, shoulder, groin, digit, vulva, extremities, and trunk. Because of their pathologic findings, high degree of cellularity and the presence of immature cells, they can be erroneously diagnosed as malignant tumor and can lead to overtreatment of these benign disorder. This can be avoided by an awareness of the clinical and histologic characteristics of fibrous hamartomas of infancy. The authors present one case of fibrous hamartoma of infancy developed in the trunk of extensively large size which was successfully removed.

PURPOSE: The purpose of this study was to examine the effect of lifestyle intervention on the development of fatigue, nutritional status and quality of life of patients with gynecologic cancer. METHODS: A nonequivalent control group quasi-experimental design was used. Participants were 49 patients with gynecologic cancer. They were assigned to the experiment group (n=24) or the control group (n=25). The lifestyle intervention for this study consisted of physical activity, nutritional education, telephone call counseling, health counseling, monitoring for lifestyle, and affective support based on Cox's Interaction Model of Client Health Behavior and was implemented for six weeks. RESULTS: Significant group differences were found for fatigue (p =.037), nutritional status (p =.034) and social/family well-being (p =.035) in these patients with gynecologic cancer. CONCLUSION: Results indicate that this lifestyle intervention is effective in lessening fatigue, and improving nutritional status and social/family well-being. Therefore, nurses in hospitals should develop strategies to expand and provide lifestyle interventions for patients with cancer.

PURPOSE: The ketogenic diet has long been used to treat epilepsy, but its mechanism is not yet clearly understood. To explore the potential mechanism, we analyzed the changes in gene expression induced by the ketogenic diet in the rat kainic acid (KA) epilepsy model. MATERIALS AND METHODS: KA-administered rats were fed the ketogenic diet or a normal diet for 4 weeks, and microarray analysis was performed with their brain tissues. The effects of the ketogenic diet on cathepsin E messenger ribonucleic acid (mRNA) expression were analyzed in KA-administered and normal saline-administered groups with semi-quantitative and real-time reverse transcription polymerase chain reaction (RT-PCR). Brain tissues were dissected into 8 regions to compare differential effects of the ketogenic diet on cathepsin E mRNA expression. Immunohistochemistry with an anti-cathepsin E antibody was performed on slides of hippocampus obtained from whole brain paraffin blocks. RESULTS: The microarray data and subsequent RT-PCR experiments showed that KA increased the mRNA expression of cathepsin E, known to be related to neuronal cell death, in most brain areas except the brain stem, and these increases of cathepsin E mRNA expression were suppressed by the ketogenic diet. The expression of cathepsin E mRNA in the control group, however, was not significantly affected by the ketogenic diet. The change in cathepsin E mRNA expression was greatest in the hippocampus. The protein level of cathepsin E in the hippocampus of KA-administered rat was elevated in immunohistochemistry and the ketogenic diet suppressed this increase. CONCLUSION: Our results showed that KA administration increased cathepsin E expression in the rat brain and its increase was suppressed by the ketogenic diet.

Iatrogenic spinal epidermoid tumors are rare and implanted. Implanted skin fragment by trauma or lumbar puncture is thought to be a possible cause. Because of the lag in time between the lumbar puncture and the development of a symptomatic tumor, this relationship is usually overlooked and can cause a delay in diagnosis. We present a case of intraspinal epidermoid tumor developed 7 years after a lumbar puncture.

Purpose: The use of two adjacent radiation beams to treat a lesion that is larger than the maximum field of a machine may lead to higher or lower dose distribution at the junction than expected. Therefore, evaluation of the junction dose is crucial for radiotherapy. Volumetric modulated arc therapy (VMAT) can effectively protect surrounding normal tissues by implementing a complex dose distribution; therefore, two adjacent VMAT fields can effectively treat large lesions. However, VMAT can lead to significant errors in the junction dose between fields if setup errors occur due to its highly complex dose distributions. Methods: In this study, setup errors of ±1, ±3, and ±5 mm were assumed during radiotherapy for treating large lesions in the lower abdomen, and their effects on the treatment dose distribution and target coverage were analyzed using gamma pass rate (GP) and homogeneity index (HI). All studies were performed using a computational simulation method based on our radiation treatment planning software. Results: Consequently, when the setup error was more than ±3 mm, most GP values using a 3%/3-mm criterion decreased by <90%. GP was independent of the direction of the field gap (FG), whereas HI values were relatively more affected by negative values for FG. Conclusions Therefore, the size and direction of setup errors should be carefully managed when performing dual-isocentric VMATs for large targets.

Background: Prevention of osteoporosis and bone fracture is one of the important issues for liver transplant recipients because a long history of liver disease and lifelong use of immunosuppressants, including corticosteroids, may cause these diseases. In this study, we aimed to analyze liver recipient bone status, 10-year fracture risk, and medication history. Methods: The electronic medical records of adult patients aged >40 years who received liver transplantation at Seoul National University Bundang Hospital between January 2009 and June 2017 were reviewed retrospectively. On the basis of their bone mineral density and fracture history, their fracture risks were analyzed using the Korean fracture risk assessment tool. Results: A total of 57 liver transplant recipients were treated with corticosteroids during a mean of 8.8 months after transplantation. 30 patients (52.6%) showed bone metabolism dysfunction such as osteopenia or osteoporosis. The 10-year femoral fracture risk was 2.1%, and dual-energy X-ray absorptiometry monitoring was performed, including right before liver transplantation every 27.5±19.2 months. The mean femoral bone mineral density decreased by −7.2%±7.3%. Four patients (7.0%) had a fracture after liver transplantation. Osteoporotic fracture occurred in 3 patients with osteoporosis (25.0%). Among the osteopenia patients with moderate fracture risk who were not treated with bisphosphonate, 1 patient (12.5%) had a history of bone fracture after liver transplantation. Conclusions Considering the deterioration of bone density and moderate fracture risk, medication for osteoporosis should be prescribed to liver transplant recipients with regular monitoring of bone density after transplantation.
