Lanolin is a complex material consisting of a mixture of numerous esters and polyesters of high-moleculer-weight alcohols and fatty acids, Lanolin allergy is important because lanolin is widely used as an emulsifier in topical medicaments and in numerous cosmetic preparations. We report a case of allergic contact dermatitis in a 27-year-old female. An erythematous pruritic rash develgood around the eyelid developed after applying a new eye cream and was aggravated after applying Cambison ophthalmic ointment. Patch testing showed positive reactions to Cambison ophthalmic ointment, 30% wool alcohol, Amerchol L101 and Nivea cream. A use test with 100% Cambison ophthalmic ointment base was positive

Objective: This study aims to identify the usefulness of voice function in early screening for dysphagia. We sought to evaluate if screening tests through the functions of production and quality of voice were correlated with aspiration in dysphagic patients. Methods: This study involved 55 participants who were referred to videofluoroscopic swallowing study (VFSS) for suspected dysphagia. Blinded examiners rated the voice production function (MVI, MPT) using a portable instrument and evaluated the quality of voice (jitter, shimmer, NHR) using Visi-pitch. Swallowing functions were also evaluated by utilizing the penetration-aspiration scale (PAS), American Speech-Language-Hearing Association (ASHA), National Outcome Measurement System (NOMS) swallowing scale and VDS. The patients were divided into two groups, the penetration group, and the aspiration group according to the PAS score. The difference in variables was analyzed using the Mann-Whitney U test between the two groups. The relationship between voice parameters and swallow-related parameters was determined using the Spearman correlation coefficient. In addition, the cut-off, sensitivity, and specificity of meaningful variables in silent aspiration were analyzed using the ROC curve analysis. Results: The functions of production and quality of voice were found to be significantly different between the penetration and aspiration groups (P＜.000). The PAS score was correlated with all parameters of the functions of production and quality of voice (P＜.001). VDS was correlated with MVI, ASHA was correlated with MVI, and Shimmer (P＜.001). The meaningful variables for silent aspiration were jitter and shimmer. Conclusion Through a clinical screening test, it may be possible to predict the difference between penetration and aspiration through the functions of production and quality of voice.

Aggregatibacter actinomycetemcomitans is an important pathogen in the development of localized aggressive periodontitis. Lipopolysaccharide (LPS) is a virulent factor of periodontal pathogens that contributes to alveolar bone loss and connective tissue degradation in periodontal disease. Our present study was designed to investigate the cytokine expression and signaling pathways regulated by A. actinomycetemcomitans LPS (Aa LPS). Cytokine gene expression profiling in RAW 264.7 cells was performed by microarray analyses. The cytokine mRNA and protein levels and related signaling pathways induced by Aa LPS were measured by RT-PCR, ELISA and western blotting. Microarray results showed that Aa LPS strongly induced the expression of NF-kappaB, NF-kappaB-related genes, inflammatory cytokines, TNF-alpha and IL-1beta in RAW 264.7 cells. NF-kappaB inhibitor pretreatment significantly reduced the levels of TNF-alpha and IL-1beta mRNA and protein. In addition, the Aa LPS-induced TNF-alpha and IL-1beta expression was inhibited by p38/JNK MAP kinase inhibitor pretreatment. These results show that Aa LPS stimulates TNF-alpha and IL-1beta expression through NF-kappaB and p38/JNK activation in RAW 264.7 cells, suggesting the essential role of this pathway in the pathogenesis of localized aggressive periodontitis.

We report 4 cases of malignant thymoma which were composed of 2 cases of invasive thymoma and 2 cases of thymic carcinoma. The cytologic findings of invasive thymoma were similar to those of benign thymoma. The distinctive cytologic features of thymic carcinoma were necrotic background, irregular clusters and individually scattered arrangement of anaplastic epithelial cells, and some scattered mature small lymphocytes. These findings may be found in the Hodgkin's lymphoma, seminoma, and metastatic squamous cell carcinoma, undifferentiated carcinoma, and large cell carcinoma of the lung. But, the feature of irregular clustering of anaplastic epithelial cell having scanty cytoplasm was different from Hodgkin's lymphoma and seminoma. Clinical and radiologic findings as well as cytologic finding were helpful in differential diagnosis of thymic carcinoma from metastatic carcinoma.

Biliary atresia is a progressive obliterative cholangiopathy. However, the actual causes remain unknown, although a number of factors such as developmental malformation, viral infection, toxicity of bile constituents, and anatomic abnormality in the hepatobiliary system have been considered. Recently, several studies have been done to find out specific gene expression. Some cases of biliary atresia are associated with anomalies of cardiovascular system, digestive tract and spleen. Few cases of biliary atresia with congenital ileal atresia were reported. We experienced a case with biliary atresia combined with ileal atresia. Ileal resection and end to end anastomosis operation were done at second days of the life because of congenital ileal atresia. Jaundice and acholic stool were noticed a few days after the operation. He was diagnosed as biliary atresia and received Kasai operation at 23 days of the life. Therefore, we report the case with a brief review of the related literature.

PURPOSE: Ghrelin stimulates the secretion of growth hormone and other pituitary hormones, and has orexigenic effects. It may have a physiologic role in fetal and neonatal growth. Leptin secreted by the adipocytes reflects fat mass in infants as well as adults. The aim of this study was to evaluate the relation of cord blood ghrelin and leptin levels to body weight(BW), body mass index(BMI), insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding protein-3(IGFBP-3) levels in appropriate for gestational age(AGA) newborns. METHODS: Sixty healthy AGA newborns(31 males and 29 females, gestational age[GA] 34-42 weeks) were included in this study, whose BW and BMI were measured at delivery. Umbilical cord venous blood samples were withdrawn, and ghrelin and leptin were measured by radioimmunoassay. Cord blood IGF-I and IGFBP-3 were determined by immunoradiometric assay. RESULTS: The mean levels of ghrelin were inversely correlated with BW(r=-0.29, P<0.05) and GA (r=-0.28, P<0.05), but were not affected by gender. The mean levels of leptin levels showed positive correlation with BW(r=0.44, P<0.01), GA(r=0.36, P<0.01), and BMI(r=0.28, P<0.05). The leptin levels of females were higher than those of males. There was no gender difference in leptin levels in neonates under GA 37 weeks. However, the leptin levels of females were higher than those of males (P<0.01) in newborns with GA 37 weeks or over. There was no correlation between ghrelin and leptin levels. Ghrelin and leptin levels showed no relations to cord blood IGF-I and IGFBP-3 levels. CONCLUSION: These data suggest that cord blood ghrelin may have an inverse correlation with BW in AGA newborns, and leptin levels are positively correlated with BW and fat mass. Further study of ghrelin concentrations in cord blood is necessary to elucidate the physiological and pathological roles of ghrelin during the fetal and neonatal periods.

PURPOSE: Dexmedetomidine, a potent selective alpha2-adrenergic agonist, produces sedation and analgesia. This study was conducted to assess the effect of dexmedetomidine infusion on sevoflurane requirements, recovery profiles, and emergence agitation in children undergoing ambulatory surgery. MATERIALS AND METHODS: Forty children undergoing ambulatory hernioplasty or orchiopexy were randomized into two groups. The dexmedetomidine group (Group D, n=20) received dexmedetomidine 1 microg/kg, followed by 0.1 microg/kg/h until the end of surgery, whereas the saline group (Group S, n=20) received volume-matched normal saline. Sevoflurane was used for induction and maintenance of anesthesia and caudal block was performed in all children. End-tidal sevoflurane concentration (ET-sevo), the incidence of emergence agitation, pain scores, and sedation scores were recorded. Hemodynamic changes and other adverse effects were assessed in the perioperative period. RESULTS: ET-sevo of Group D was significantly reduced in 23.8-67% compared to Group S during surgery. The incidence of emergence agitation was lower in Group D than in Group S (5% vs. 55%, p=0.001). Postoperative pain was comparable, and discharge time was not different between the groups. Mean arterial pressure and heart rate were significantly lower in Group D during surgery. CONCLUSION: Intraoperative infusion of dexmedetomidine reduced sevoflurane requirements and decreased emergence agitation without delaying discharge in children undergoing ambulatory surgery. However, caution should be taken in regard to bradycardia and hypotension.

Neuroendocrine tumors derive from the diffuse neuroendocrine system producing hormonal peptides and/or biogenic amines. Histologically neuroendocrine differentiation includes ultrastructural demonstration of neurosecretory granules and staining with immunhistochemical markers such as neuron-specific enolase, chromogranin, synaptophysin, and cytokeratin. Neuroendocrine carcinoma of the skin is rare but can be shown as an initial manifestation of metastatic neuroendocrine carcinoma as well as primary cutaneous neuroendocrine carcinoma. Histological differentiation between primary cutaneous Merkel cell carcinoma and metastatic neuroendocrine carcinoma of the skin is difficult and clinical correlation is important. We report a case of metastatic neuroendocrine carcinoma of the lung occurring on the scalp as a single nodule in a 65-year-old female who previously diagnosed with adenocarcinoma of the stomach.

Corals are the marine organism that belongs to the phylum Cnidaria, and are one of the common causes of superficial injury in the marine environment. In addition to acute reactions such as burning or stinging pain and erythema, coral injuries may present with complications such as foreign body reactions, bacterial infections, and/or localized eczematous reactions. A 23-year-old male presented with an erythematous edematous tender patch with centrally grouped vesicles on the left ankle; the injury had occurred during skin-scuba diving 2 days before. A biopsy of the lesion treated with hematoxylin-eosin stain showed epidermal necrosis with subepidermal blisters and neutrophilic panniculitis. Herein we report a case of cellulitis caused by the nematocyst stings of corals.
