Dysarthric patients often present velopharyngeal incompetence (VPI), characterized nasalization articulation for hypernasality,which seriously impaired their communication. Research of evaluation of VPI is mainly about cleft palate and postoperative, few about the dysarthria. Some approaches, such as physiologic approach to rehabilitation, have been used to correct hypernasality, and prosthesis,such as palatal lift prosthesis (PLP) and nasal speaking valve (NSV), are also proved effectively. PLP has been widely used for hypernasality oversea, but fewer in China.

The columnar cell variant of papillary carcinoma is a rare tumor of the thyroid, associated with aggressive behavior, early metastasis, and a rapidly fatal course. We present the fine needle aspiration cytologic(FNAC) findings of columnar cell variant of papillary carcinoma with cytohistologic correlation. In the smears, the tumor fragments showed mainly papillary pattern and a few scattered individual cells were present around the papillary fragments. The tumor cells were columnar or cuboidal and exhibited pseudostratification of the nuclei. The nuclei were oval to elongated with finely stippled chromatin and inconspicous nucleoli. Neither nuclear grooves nor intracytoplasmic inclusion was found. The FNAC diagnosis was consistent with papillary carcinoma. Total thyroidectomy was done and the histologic finding of the mass showed a predominantly papillary and focal solid proliferation of columar cells with marked nuclear pseudostratification. The unique histopathologic features and highly aggressive nature of columnar cell variant of papillary carcinoma require that this variant should be differeniated from common papillary carcinoma of the thyroid.

BACKGROUND: Hepatitis C virus (HCV) RNA quantification is necessary for predicting the therapeutic response and assessing treatment results in patients with chronic HCV infection. Recently, real-time PCR technology for HCV RNA quantification displayed good linearity within the dynamic range. Thus, it is gradually replacing branched-DNA (bDNA) and PCR- hybridization assays. In this study, we evaluated the performance of the Real-QTM HCV quantification kit (biosewoom. Inc., Seoul, Korea) developed in Korea. METHODS: We evaluated the HCV quantification kit for detection limit, specificity, linearity, accuracy, and recovery rate of HCV RNA standard material. The results were analyzed for a correlation with those of Cobas Amplicor HCV Monitor 2.0. RESULTS: The HCV quantification kit showed a high recovery rate of HCV RNA standard material of various concentrations and amplication of HCV RNA equally in all genotypes. Hepatitis B virus and human immunodeficiency virus showed no cross-reactivity with HCV. Within-run and between-run coefficients of variation (CV) were 9.52~15.84% and 9.40~17.53%, respectively. Between-day coefficients of variation were 11.62~18.04%, and detection limit was 44 IU/mL. It showed a good correlation with Cobas Amplicor HCV Monitor 2.0 (R2=0.8954). CONCLUSION: The Real-Q HCV quantification kit showed a good specificity, sensitivity, linearity, and accuracy; therefore, we propose that it is fully adequate for monitoring antiviral therapy in patients with chronic HCV infection.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea. The subjects were 64 Chinese college students in Korea (educated group, 32 students vs. non-educated group, 32 students). Educated group was lessoned as group and/or individual. Nutrition education program consisted of four lessons (40min / lesson), '6 major nutrients & function (group lesson)', '6 food group and sources (group lesson)', 'personalized daily needed energy and food exchange units using Food Exchange System (individual lesson)', and 'smart choice of snacks and eating-out foods (group lesson)'. We examined the differences between educated group and non-educated group in nutrition knowledge, dietary attitudes and nutrients intake. After education, there were positive improvements on nutrition knowledge: 'function and foods of 6 nutrients', on dietary attitudes: 'type of breakfast' in educated group. In the evaluation of nutrient intakes according to Dietary Reference Intakes for Korean (KDRI), there were positive improvements on intake levels of riboflavin, fiber, vitamin B6, vitamin C, folate, Ca and K in the educated group. In the index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased in the educated group. In conclusion, it is possible to improve nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea through the nutrition education focused on personalized daily needed energy and food exchange units.

Taste-responsive neurons in the nucleus of the solitary tract (NST), the first gustatory nucleus, often respond to thermal or mechanical stimulation. Alcohol, not a typical taste modality, is a rewarding stimulus. In this study, we aimed to investigate the effects of ethanol (EtOH) and/or temperature as stimuli to the tongue on the activity of taste-responsive neurons in hamster NST. In the first set of experiments, we recorded the activity of 113 gustatory NST neurons in urethane-anesthetized hamsters and evaluated responses to four basic taste stimuli, 25% EtOH, and 40°C and 4°C distilled water (dH2O). Sixty cells responded to 25% EtOH, with most of them also being sucrose sensitive. The response to 25% EtOH was significantly correlated with the sucrose-evoked response. A significant correlation was also observed between sucrose- and 40°C dH2O- and between 25% EtOH- and 40°C dH2O-evoked firings. In a subset of the cells, we evaluated neuronal activities in response to a series of EtOH concentrations, alone and in combination with 32 mM sucrose (EtOH/Suc) at room temperature (RT, 22°C–23°C), 40°C, and 4°C. Neuronal responses to EtOH at RT and 40°C increased as the concentrations increased. The firing rates to EtOH/Suc were greater than those to EtOH or sucrose alone. The responses were enhanced when solutions were applied at 40°C but diminished at 4°C. In summary, EtOH activates most sucrose-responsive NST gustatory cells, and the concomitant presence of sucrose or warm temperatures enhance this response. Our findings may contribute to elucidate the neural mechanisms underlying appetitive alcohol consumption.

PURPOSE: There is an unmet need for the treatment of moderate-to-severe atopic dermatitis (AD), leading to variation in management strategies. To investigate distinct features and treatment modalities according to physicians' specialties, we collected data on the current treatment approach to moderate-to-severe AD among allergists, pediatric allergists and dermatologists in Korea. METHODS: This questionnaire-based study was administered to physicians from the Korean Academy of Asthma, Allergy and Clinical Immunology (KAAACI), Korean Academy of Pediatric Allergy and Respiratory Disease (KAPARD), and Korean Atopic Dermatitis Association (KADA). RESULTS: A total of 93 physicians participated in the study; 64.5% were pediatric allergists and 31.2% were dermatologists. The major patient age groups were “less than 5 years” for 100% of pediatric allergists and “6–12 years old” for 38% of dermatologists. The proportion of patients with moderate-to-severe AD was higher for dermatologists and allergists compared to pediatric allergists. Physicians agreed on the necessity of education including demonstration of basic skin care and application of topical therapies (88.2%), nutritional consultation (83.9%) and psychological counseling (75.3%). However, less than half were able to educate and counsel their patients in real practice. There were noticeable differences in first-line treatment among physician groups. For pediatric allergists, the order of preferred systemic treatment was wet wrap therapy, systemic corticosteroids and oral cyclosporin. Dermatologists ranked cyclosporin, phototherapy, and systemic corticosteroids as first-line treatment regimens. Major reported barriers to proper management were steroid phobia, unproven complementary and alternative medicine, lack of education, and the unreasonable insurance system. CONCLUSIONS: Our findings suggest there are distinct differences in moderate-to-severe AD treatment according to physicians' specialties. Medical policy changes along with governmental supports are required in order to implement the ideal approach in real practice. For moderate-to-severe AD, a consensus on the approach to optimal management should be reached for the best outcomes, based on further randomized controlled trials.

PURPOSE: To identify nursing interventions performed by Chosunjok nurses in Yanbian using NIC. METHODS: The sample consisted of 36 nurses working in 2 hospitals. The Nursing Interventions Use Questionnaire developed by the Iowa Intervention Project team was used for data collection. The instrument was translated to Korean using the method of back-translation. RESULTS: Twenty-eight interventions were performed at least daily. Interventions in the Physiological: Basic domain were most frequently used at least daily. The most frequently used interventions was Positioning, followed by the interventions Pressure Ulcer Prevention, Intravenous (IV) Therapy, Hypothermia Treatment and Intravenous (IV) Insertion. The least frequently used interventions was Electronic Fetal Monitoring: Antepartum. Nurses working in special medical care units performed interventions most often, while nurses working in general surgical units performed them least. Nurses working in general medical, special medical and other care units performed interventions in the Physiological domain more often than the nurses working in general surgical units. CONCLUSION: Chosunjok nurses in Yanbian performed physiological interventions frequently. Further studies will be needed to compare interventions performed by nurses in two countries.

BACKGROUND: There have been several reports of patients with a severe hydroa vacciniforme (HV)-like eruption from Asia and Latin America. The cutaneous lesions are present in both sun-exposed and nonexposed areas in these patients unlike true HV. Several patients have died of malignant hematologic malignancies. The latent Epstein-Barr virus (EBV) infection has been detected in the skin lesions of the patients. OBJECTIVE: To describe clinical, histological, immunohistochemical, and molecular pathological features of the patients with EBV associated lymphoproliferative lesion presenting as a HV-like eruption. METHODS: The clinical, histological, and immunohistochemical features of 16 patients were reviewed. The presence of T-cell receptor (TCR)-gamma gene rearrangement was investigated using polymerase chain reaction (PCR) technique. Photoprovocation by repetitive UVA exposure was performed in five patients. In situ hybridization was performed to detect mRNA for EBV in the lesional skin biopsy specimen, lymph node biopsy specimen, mucosal biopsy specimen of stomach, and the skin biopsy specimen of photo-provoked site. PCR was performed to detect DNA for EBV in the skin biopsy specimens of 6 patients and peripheral mononuclear cells of 2 patients. RESULTS: The severity of the skin lesion and the clinical course varied among the patients. Skin biopsy specimens obtained from a papule or a vesicle showed perivascular and periadnexal infiltrate of lymphoid cells with T-cell phenotype. However, clonal TCR-gamma gene rearrangement was not detected in all 8 patients. Papules or vesicles were induced by repetitive UVA exposure in 5 patients. A latent EBV infection was demonstrated in all the tested samples, such as lesional skin, lymph node, gastric mucosa, peripheral blood mononuclear cells, and the photo-provoked lesion. CONCLUSION: EBV associated lymphoproliferative lesion presenting as a HV-like eruption is a novel disease that is not related to classic HV. Repetitive irradiation of UVA can induce the skin lesion in some patients with EBV associated lymphoproliferative lesion presenting as a HV-like eruption.
