Background Recurrent herpes labialis (RHL) is a common recurrent infective vesiculoulcerative disease. Topical and systemic administration of Zinc compounds has been indicated to have preventive and therapeutic effects. The purpose of this study was to evaluate the serum level of zinc in the patients with RHL and healthy individuals and also to investigate the correlation of this level with various parameters of the patient and disease course. Methods This cross-sectional study was performed on 43 patients with a history of recurrent herpers labialis and 42 subjects without any previous experience of the lesion. Blood samples were taken, and serum zinc level was measured using colorimetry (spectrophotometry) method. Chi-Square test was used to compare the qualitative relationships, and for comparing the quantitative relationships, independent T-test was used. To observe the relationship of quantitative factors including serum zinc level, the number of relapses, and recovery rates, correlation test was taken. Results The results show that, serum zinc level has no significant difference between healthy subjects and the patients (p > 0.05). Also, zinc level was not related to age and sex factors and frequency of relapse (p > 0.05). However surprisingly, there was a significant relationship between zinc level and recovery period in the RHL patients. The lower the serum zinc level, the higher the duration of recovery (p = 0.009). Conclusion The results of this study indicate that, zinc deficiency can be considered as a risk factor for increasing the duration of herpes labialis lesions. Therefore, the evaluation of serum zinc level in the subjects with RHL and subsequent administration of zinc are recommended in these kind of patients.

Background. Oro-dental diseases are prevalent in chronic liver failure (CLF) patients. The aim of this study was to evaluate the quality of life associated with oral health in candidates for liver transplant surgery. Materials and Methods. The demographic information of 105 end-stage liver cirrhotic patients was collected. All patients were ordered a panoramic view for pretransplant dental evaluation. The DMFT (decayed-missing-filled tooth) index was calculated for dental examination. The model for end-stage liver disease (MELD) was used for the severity of liver disease. The OHIP-14 (Oral Health Impact Profile) questionnaire and GOHAI (Geriatric Oral Health Assessment Index) questionnaire were applied to evaluate the impact of oral disease on the quality of life. Results. A total of 79 patients thoroughly completed the questionnaires; 79.7% were male, 32.9% were over 50, and 25.3% were less than 30 years old. Further, 12.7% smoked, 2.5% were illiterate, 64.6% had not finished school, and 10.1% had university degrees. Almost half of the cirrhotic patients were suffering from the disease for more than 3 years. Most complaints reported by the patients as “very often” were becoming self-conscious (13.9%) and being uncomfortable when eating any foods (13.9%) followed by feeling tense (12.8%). There was no significant difference between gender, smoking, age, and MELD score based on quality of life (OHIP and GOHAI) ( P > 0.05 ). The level of education ( P = 0.020 ), duration of disease ( P = 0.017 ), and DMFT index ( P = 0.039 ) had a significant impact on oral health-related quality of life in CLF patients. An inverse relationship was seen between the DMFT index and the quality of life. Conclusion. Oral health has a high impact on the quality of life of cirrhotic patients. The psychological dimension of oral health is the most debilitating factor affecting the quality of life. This shows the importance of professional oral care, oral health, and self-care education in this group of patients.

Background: Recurrent herpes labialis (RHL) is one of the most common recurrent infective vesiculoulcerative lesions. Topical and systemic administration of Zinc compounds has been found to have preventive and therapeutic effects. The purpose of this article is to evaluate the serum level of zinc in patients with RHL and healthy individuals.Methods: This cross-sectional study was performed on 43 patients with the history of recurrent herpers labialis and 42 healthy subjects with no history of the lesion. Blood samples were taken and serum zinc level was measured. Chi-Square test was used to compare the qualitative relationships and to compare the quantitative relationships independent T-test was used. To observe the relationship of quantitative factors including serum zinc level, the number of relapses and recovery rates correlation test was taken.Results: The results show that serum zinc level has no significant difference in healthy subjects and patients (p> 0.05). Also, zinc level was not related to age and sex factors and frequency of relapse (P> 0.05). But surprisingly in the patients group, there was a significant relationship between zinc level and recovery period. As the serum zinc level was lower, the duration of recovery was significantly higher (p =0.009). Conclusion:The results of this study indicate that zinc deficiency is a risk factor for increasing the duration of herpes labialis lesions. Therefore, the evaluation of serum zinc level in subjects with recurrent herpes labialis and subsequent administration of zinc is recommended in such patients. Background:Herpes simplex virus type 1 (HSV-1) a member of the herpes virus family is the etiologic factor of a variety of diseases. It generally affects the upper parts of the human body. The primary infection appears after fluid or skin contact with contaminated individuals. The virus tends to remain in the sensory ganglions or skin epithelium after the initial infection, in most cases. Factors such as sunlight, shock, stress, fever, and hormonal changes can trigger a secondary or recurrent lesion such as herpes labialis.(1, 2) Herpes labialis appears primarily as a vesicle in the skin area around the oral cavity, lips, nose or the

In this paper we investigate some fundamental properties of unital topology on a lattice ordered group with order unit. We show that some essential properties of order unit norm on a vector lattice with order unit, are valid for unital l-groups. For instance we show that for an Archimedean Riesz space G with order unit u, the unital topology and the strong link topology are the same.
