Prevalence of salivary Epstein-Barr virus in potentially malignant oral disorders and oral squamous cell carcinoma.
2015
Background: To analyze the presence of salivary Epstein-Barr virus (EBV) DNA in oral squamous cell carcinoma and potentially malignant oral disorders. Material and Methods: Three groups were studied: Group 1 (12 oral squamous cell carcinomas (OSCC)), Group 2 (12 potentially malignant oral disorders (PMD)) and Group 3 (47 healthy controls). EBV DNA salivary analysis was performed by PCR. Results: The highest percentage of positive salivary EBV DNA corresponded to the OSCC group (58.3%), followed by the PMD group (41.7%) and the controls (40.4%). The differences between groups were not statistically significant, however (p>0.05). Conclusions: Salivary EBV DNA was more prevalent in OSCC than i…
Psychological Conflicts Between Relatives During the Long-Term Course After Successful Living Organ Donation
2008
The German transplantation law prefers living organ donation between close relatives and spouses, which is assumed to guarantee unequivocal altruistic motivation. Since 2001, 68 recipient-donor-pairs, who aspired to have a renal or liver transplantation, underwent a systematic psychosomatic evaluation. Meanwhile, 43 transplantations were performed including 34 renal and 9 liver cases. Seventeen recipient-donor-pairs were readministered evaluations by the department of psychosomatic medicine after 1 to 6 years after transplantation for long-term follow-up. In 10 cases of medically successful transplantation, we identified severe conflicts between donor, recipient, and next-of-kin. Major conf…
Mid-Term Effectiveness of Behavioral and Psychodynamic Inpatient Treatments of Severe Obesity Based on a Randomized Study
2006
<i>Background:</i> The objective of this study was to compare the effectiveness of psychodynamic and behavioral inpatient treatments of severely obese patients regarding weight and distress. <i>Methods:</i> In a longitudinal study obese patients (body mass index, BMI ≧35) were randomly assigned to behavioral or to psychodynamic inpatient treatment. Mostly female (n = 267; 85%) obese patients with psychiatric and somatic comorbidity (age 20–64 years, BMI 35–74) were examined with standardized self-report scales on distress (SCL-90R), interpersonal problems (Inventory of Interpersonal Problems), eating behavior (Fragebogen zum Essverhalten) and body image (Fragebogen z…
Covariation of spectral and nonlinear EEG measures with alpha biofeedback.
2002
Item does not contain fulltext This study investigated how different spectral and nonlinear EEG measures covaried with alpha power during auditory alpha biofeedback training, performed by 13 healthy subjects. We found a significant positive correlation of alpha power with the largest Lyapunov-exponent, pointing to an increased dynamical instability of the EEG accompanying alpha enhancement. Alpha power amplification, moreover, was significantly correlated with a decrease of spectral entropy within the alpha range. This outcome reflects a sharpening of the alpha peak during biofeedback training. The fact that the sharpening effect clearly preceded the increase of alpha amplitude could be exp…
Severe herpes simplex virus type-I infections after dental procedures
2010
Background: Recurrences of herpes labialis (RHL) may be triggered by systemic factors, including stress, menses, and fever. Local stimuli, such as lip injury or sunlight exposure are also associated to RHL. Dental extraction has also been reported as triggering event. Case reports: Seven otherwise healthy patients are presented with severe and extensive RHL occurring about 2-3 days after dental extraction under local anaesthesia. Immunohistochemistry on smears and immunofluorescence on cell culture identified herpes simplex virus type I (HSV-I). Five patients reported more severe prodromal signs than usual. Although all the patients suffered from RHL, none had previously experienced RHL aft…
Infection with human herpes virus type 8 in an area at high prevalence for hepatitis C virus infection in southern Italy
2004
Summary. The Campania Region is a geographical area of southern Italy characterized by high incidence rates of hepatocellular carcinoma and of classic Kaposi's sarcoma. Epidemiological investigations carried out among different population groups in this region have found high prevalence rates of both hepatitis C virus (HCV) and human herpesvirus type 8 (HHV-8). To assess co-infection rates of HCV and HHV-8, we carried out a cross-sectional seroepidemiological study prevalence in Pomigliano d'Arco, a Health District of Campania located 20 km away from Naples. The overall rate of HCV/HHV-8 co-infection was 3.1%, 3.5% among men and 2.7% among women. No difference emerged in the HCV/HHV-8 co-i…
Selected Predictors of the Sense of Intimacy in Relationships of Young Adults
2019
The main research objective of this study was seeking the predictive role of closeness to parents, attachment, identity style, identity commitment, type of relationship, and having children in intimacy among young women and men. Many studies indicate differences in the level of engagement, communication, and satisfaction in relationships. The study group comprised 227 people, including 114 women (M = 29.99
Nested PCR for detection of HSV-1 in oral mucosa
2015
Background: It has been estimated that 15%-20% of human tumours are driven by infection and inflammation, and viral infections play an important role in malignant transformation. The evidence that herpes simplex virus type 1 (HSV-1) could be involved in the aetiology of oral cancer varies from weak to persuasive. This study aimed to investigate by nested PCR (NPCR) the prevalence of HSV-1 in samples from normal oral mucosa, oral leukoplakia, and oral squamous cell carcinoma (OSCC). Material and Methods: We investigated the prevalence of HSV-1 in biopsies obtained from 26 fresh, normal oral mucosa from healthy volunteers as well as 53 oral leukoplakia and 27 OSCC paraffin-embedded samples. D…
Acute acalculous cholecystitis during the course of primary Epstein–Barr virus infection: a new case and a review of the literature
2008
Summary Objective The aim of this study was to describe a case of acute acalculous cholecystitis occurring in the course of primary Epstein–Barr virus (EBV) infection. Methods The clinical features of the case were analyzed and compared to those of three other similar cases reported in the international literature. Results All cases occurred in European females with cholestatic hepatitis, presented with gallbladder wall thickening, and recovered uneventfully without the need for surgical intervention. Conclusions Acute acalculous cholecystitis may occur during the course of acute EBV infection, especially in patients with cholestatic hepatitis. Clinicians should be aware of the possible inv…
Transfer of aciclovir from plasma to human breast milk.
2011
Aciclovir (CAS 59277-89-3) is frequently used in herpes simplex virus diseases, but administration to lactating women occurs only rarely. Therefore, information about the pharmacokinetics of aciclovir in human breast milk is limited. The concentration in breast milk is 2 to 3 fold increased compared to plasma. The reason for this increase is unknown until now. An active transport mechanism has been assumed. The aim of this study was to prove whether the higher concentration of aciclovir in human breast milk is due to only a passive transfer. Two chambers separated by a semipermeable membrane were used. The first chamber contained plasma with aciclovir, the second chamber breast milk without…
