The purpose of this study was to evaluate the effect of the nutrition education on preschool children's nutrition knowledge and behaviors. The study subjects were preschool children attending J kindergarten located in Wonju. Each of the control group and the education group consisted of 49 children and the education group was exposed to nutrition education while the control group did not. The nutrition education intervention lasted 9 weeks weekly basis. The t-test for the homogeneity of each group showed no meaningful difference at the beginning point of nutrition education. After nutrition education a test of nutrition knowledge using picture-questionnaire was carried out by the researcher for the subjects of education group and control group and the caretakers of the education group were offered self-administered questionnaire on the changes in children's dietary behaviors. The results of the study were as follows: 1. Nutrition education intervention showed a meaningful difference in children's understanding nutrition; the kinds and function of food, the relationship between food and body, the function of nutrients and enhanced their idea on hygiene compared to the control group (p < p.005). 2. However, nutrition education intervention made no statistically meaningful difference in children's dietary behaviors such as having breakfast, keeping balanced diet, washing hands before meals, saying "thanks" before and after meals, cleaning the table after meals, brushing teeth after meals and so on. Therefore, we found that it is hard to expect children to correct their dietary behaviors in such a short period of 9 weeks and nutrition education for preschool children should be offered to caretakers at the same time.

Methoxy polyethylene glycol-epoetin beta (Mircera(R), Roche), a third-generation erythropoiesis-stimulating agent (ESA) is known as a continuous erythropoietin receptor activator (CERA). In patients with anemia associated with chronic kidney disease (CKD), it is administered intravenously or subcutaneously. Treatment-related adverse events induced by methoxy polyethylene glycol-epoetin beta occurred in 6%. Hypertension, diarrhea and nasopharyngitis were the most commonly reported adverse events. Cutaneous adverse reactions are rarely experienced with methoxy polyethylene glycol-epoetin beta including maculopapular eruption, facial erythema, and tinea pedis. To the best of our knowledge, no cases of leukocytoclastic vasculitis associated with methoxy polyethylene glycol-epoetin beta have ever been published in medical literature. Herein, we report on a case of leukocytoclastic vasulitis induced by methoxy polyethylene glycol-epoetin beta in a patient with anemia associated with chronic kidney disease.

Psoriasis vulgaris is one of the most common skin diseases in the world, which is recognized as an autoimmune disease that is caused by genetic and environmental factors. Plaque, guttate, pustular form, and psoriatic erythroderma are known as classical feature of psoriasis with tendency as generalized or sporadic appearance. There are some cases of uncommon forms in the shape and distribution, as nevoid and linear psoriasis. Linear psoriasis is a rare entity and thought as a variant of psoriasis, but its existence is still in debate. Herein, we report an interesting case of 19-year old Korean man with psoriasis, occurring on the right arm, following the line of Blaschko in a linear form.

Meconium peritonitis is a non-bacterial foreign body and chemical peritonitis caused by meconium contamination resulting from bowel perforation during late intrauterine or early neonatal periods. Prenatal ultrasonographic diagnosis of the meconium peritonitis provides the preparation for proper management and decreasing motality and morbidity of the neonate. We have experienced a case of meconium peritonitis diagnosed by ultrasonography at 34+4 gestational weeks and presented this case with a brief review of the literatures.

Chondroid syringoma is referred as mixed tumor because it has epithelial structure and mesenchymal elements. Mixed tumors could be divided into two distinct types, eccrine and apocrine. Mixed tumor with follicular, sebaceous and apocrine differentiation is considered as an expression of the common embryologic origin of elements of the folliculosebaceous-apocrine unit. A 32-year old manpresented with an asymptomatic firm erythematous nodule on the left cheek. Histologically, it showed typical features of chondroid syringoma with tubules exhibiting branching and cystic dilatation in the myxoid and chondroid stroma. Our case is unique in that the tumor arose from follicular infundibulum with follicular, sebacesous and apocrine differentiation.

Giant congenital melanocytic nevi (GCMN) are defined as melanocytic nevi that are greater than 20 cm in largest dimension at birth. GCMN is a relatively rare condition, affecting approximately 1 in 20,000 newborns. Patients with GCMN on the posterior axis and in the presence of many satellite nevi are associated with neurocutaneous melanosis. A 37-year-old female with mental retardation had dark brown nevi with hair on her back (paraspinal) and on her lower extremities. In addition, she has multiple satellite lesions distributed over her trunk and extremities. Herein, we present a case that demonstrates a relationship between CNS abnormality and multiple satellite nevus in GCMN patients with a review of the relevant literature.

BACKGROUND:
Ferroptosis is an iron-dependent, non-apoptotic programmed cell death. Cellular senescence contributes to aging and various age-related diseases through the expression of a senescence-associated secretory phenotype (SASP). Senescent cells are often resistant to ferroptosis via increased ferritin and impaired ferritinophagy. In this study, we investigated whether treatment with JQ1 could remove senescent cells by inducing ferroptosis.
METHODS:
Senescence of human dermal fibroblasts was induced in vitro by treating the cells with bleomycin. The senolytic effects of JQ1 were evaluated using a SA-β gal assay, annexin V analysis, cell counting kit-8 assay, and qRT-PCR. Ferroptosis following JQ1 treatment was evaluated with qRT-PCR and BODIPY staining.
RESULTS:
At a certain range of JQ1 concentrations, JQ1 treatment reduced the viability of bleomycin-treated cells (senescent cells) but did not reduce that of untreated cells (non-senescent cells), indicating that JQ1 treatment can selectively eliminate senescent cells. JQ1 treatment also decreased SASP expression only in senescent cells. Subsequently, JQ1 treatment reduced the expression of ferroptosis-resistance genes in senescent cells. JQ1 treatment induced lipid peroxidation in senescent cells but not in non-senescent cells.
CONCLUSION
The data indicate that JQ1 can eliminate senescent cells via ferroptosis. This study suggests ferroptosis as a new mechanism of senolytic therapy.

Emphysematous pyelonephritis (EPN) is a severe gas-forming infection of the renal parenchyma and surrounding tissues. Patients with EPN commonly present with high fever, chills, and flank pain. These symptoms mimic a simple urinary tract infection, such that diagnosis is often delayed. Because of its life-threatening fulminant course, the early detection of EPN and its prompt treatment with intravenous antibiotics with or without percutaneous drainage are critical. Here we describe a case of a 63-year-old Korean female with diabetes mellitus who had no specific symptoms or signs of EPN. A chest computed tomography (CT) scan to assess a right pleural effusion incidentally detected an abnormal gas shadow in the renal parenchyma. An abdominal CT scan performed 5 days later showed increased gas within the kidney parenchyma, but the patient still had no symptoms of EPN. She was treated with intravenous antibiotics alone. A follow-up abdominal CT scan revealed the complete disappearance of the features of EPN.
