Primary renal lymphoma is a rare tumor of the kidney that typically presents with bilateral nodular enlargement in the absence of extrarenal masses. We describe MR findings of a case of primary renal lymphoma along with ultrasound and CT findings. MR imaging demonstrated globular enlargement of both kidneys with multilobulated contour and multiple masses which had isosignal intensity on T1WI and low signal intensity on T2WI. The masses enhanced slightly on dynamic contrast enhanced scan.

BACKGROUND: Melasma is an acquired, symmetrical hypermelanosis that occurs on sun-exposed areas of the skin. It has significant emotional and psychological effects on those affected with the condition. Melasma Quality of Life Scale (MELASQOL) is a specific questionnaire to identify the most impaired areas of melasma patient's life. OBJECTIVE: Our purpose of this study is to investigate the changing of MELASQOL after the treatment of melasma. METHODS: A total of 27 volunteers with melasma were enrolled in this 8-week treatment study. The patients were instructed to apply an arbutin-containing cream, once a day for 8 weeks. The assessment of outcomes included the colorimetric value (L*) and MELASQOL score. RESULTS: The arbutin-containing cream group increased more in the colorimetric values (L*) after the 8-week treatment (p<0.01). The MELASQOL score was decreased (p=0.02). No significant adverse reactions were observed. CONCLUSION: The treatment of melasma improves the QOL of melasma patients.

BACKGROUNDS/OBJECTOVES: Family has an impact on dietary intake of children as a proximal food environment and family structures are changing and becoming more diverse. This study was performed to identify the association between family structure and food group intake of children aged 3-18 years in Korea. SUBJECTS/METHODS: A total of 3,217 children with complete data on variables for household information, dietary intake and sampling weights were obtained from 2010-2011 Korea National Health and Nutrition Examination Survey. Children's family structure was classified into 3 groups (Living with both parents, Living with one parent and Living without parents). To evaluate children's food group intake, scores of individual food groups ('Grains', 'Meat, Fish, Eggs and Beans', 'Vegetables', 'Fruits' and 'Milk and Dairy products') was calculated from percent adherence to the recommended servings of the Korean Food Guidance System (KFGS). 'Food group mean score' was obtained by calculating the average of five food group scores. RESULTS: After adjusting for age, sex, number of family members, and household income, children living with both parents had higher scores in 'Fruits' (P < 0.01), 'Milk and Dairy products' (P < 0.05), and mean score of individual food group score (P < 0.001) compared to children living with one parent. Individual food group scores and mean scores of individual food group scores were associated with different socio-demographic factors in study children. Family structure was associated with 'Fruits,' 'Milk and Dairy products' score and mean scores of food group scores. CONCLUSIONS: These results suggested that different approach might be required to solve nutrition problem in children depending on their family structure and other socio-demographic factors.

Liposarcoma is one of the most common soft tissue sarcoma of adults and accounts for 1% in all malignant neoplasm. A liposarcoma of perineal origin is excessively rare, and preoperative diagnosis is difficult. Perineal liposarcoma was diagnosed in a 38-year-old woman. She presented with a large soft lump in the both perineal region of 4 months duration. We report a case of a liposarcoma on perineum which was treated with complete surgical resection without adjuvant radiation therapy. The patient has survived 2 years with no evidence of a recurrence.

PURPOSE: To evaluate the clinical efficacy of a simplified single suture inferior retractor tightening technique in senile entropion. METHODS: Twenty patients (26 eyes) showing no severe horizontal lid laxity underwent an operation for senile entropion between April 2001 and July 2003. After a subciliary incision, the inferior retractor was identified, and repaired by reattaching the superior edge of the inferior retractor to the inferior edge of the lower tarsus using a single 5-0 Prolene suture. RESULTS: The patients were followed up for an average of 2.8 months after surgery. Five patients showed complications: two overcorrections and three recurrences of entropion. The others all showed good cosmetic and functional results. The recurred cases underwent further operation with good results. CONCLUSIONS: The simplified single suture inferior retractor tightening gave good results in patients with senile entropion without severe horizontal lid laxity. Moreover, this procedure has short operation and recovery times. In unilateral cases, more symmetric appearances were obtained compared with combined surgeries.

Baerobic, spore forming, and rod-shaped bacterium. Anthrax spores are introduced into macrophage by phagocytosis and multiply after germination. The anthrax spores infected in macrophage produce lethal toxin eventually caused cell death. In this study, we analyzed apoptosis and cytokine TNF-alpha and IL-12 secretion after the infection of spores of B. anthracis Sterne in the murine macrophage RAW264.7 cells and in the primary human macrophages. In murine macrophage RAW264.7 cells infected by spore of B. anthracis Sterne, the cells were markedly changed in secretion of TNF-alpha (482~6,213 pg/ml) by lethal toxin, and induced apoptosis. In case of RAW264.7 cells infected by formalin-inactivated spores of B. anthracis, the cells were not able to produce lethal toxin, which released lower level concentration of TNF-alpha (7.7~97.2 pg/ml), and rarely induced apoptosis. When primary human macrophage cells infected with spores of B. anthracis Sterne, they secreted TNF-alpha (5~16 pg/ml), and induced apoptosis about 1% of total cells. We presented that inducing apoptosis by spores of B. anthracis Sterne capable of expressing lethal toxin is related with the secretion of TNF-alpha in murine macrophage RAW264.7 cells. These studies revealed that human and murine macrophages has affected differently by anthrax lethal toxin produced by spores of B. anthracis Sterne.

Decreased number of the Neuropeptide-Y[NPY] immunoreactive neurons in the corpus striatum and primary motor cortex of aged rat was detected by the immunohistochemical method. The animals were categorized into control and aged group and we used 10 Sprague-Dawley rat weighing 250-300gm for control group. 10 Sprague-Dawley rat weighing over 600gm for aged group. The number of NPY-immunoreactive neurons in corpus striatum and primary motor cortex were counted under the light microscope and the following results were obtained. 1. The NPY-immunoreactive neurons were evenly distributed in corpus striatum and in the primaty motor cortex, the NPY-immunoreactive neurons were concentrated within the layer II, III and layer V, VI. The typical NPY-immunoreactive perikarya was multipolar shape. 2. Decreased number of NPY-immunoreactive neurons were detected in some areas of corpus striatum and primary mortor cortex of the aged rat. 3. Decrease of NPY-immunoreactive neurons were most prominent in the caudate-putamen and there were moderate decrease of NPY-immunoreactive neurons in the primary motor cortex, mild decrease of NPY-immunoreactive neurons in the nucleus accumbens but the NPY-immunoreactive neurons were not observed in the globus pallidus in both control and aged rat. NPY is supposed to act as a neurotransmitter of local circuit neurons in the striatum and may exert its potent vasoconstrictor effects on cerebral vessels which influences on the microcirculation of cerebral cortex and striatum. So our results seems to provide an important data on change of the function in the striatum and primary motor cortex of aged rat brain.
