Depression in dermatology: an integrative perspective

An example which confirmes the adequacy of the integrative perspective in medicine is depression in dermatology because of the sufficient number of arguments linking depression and some chronic skin conditions in depth more than simply comorbidity. In recent literature, the authors found, how depression in dermatology occurs significantly more frequently than in the general population. In dermatological patients the prevalence of depression is around 30% which is more in comparison to patients in general practice where prevalence of depression is 22%. The authors found a considerable similarity in the various characteristics between depression and psoriasis, based upon recent research findings in immunity disorder and elevated concentrations of proinflammatory cytokines as well as acute phase proteins in both disorders, indicating that both disorders can be considered as immunologicaly mediated, inflammatory states with repetitive chronic progress and similar comorbidity. The afore mentioned theoretical settings evoke the integrative aspect and the integrative interdisciplinary approach placing in the center of attention not only the diseased person with his fears, needs, preocupations and expectations during treatment, but the person who is at risk of becoming burdened with these disorders.     

Frequency of portal and systemic bacteremia in acute appendicitis

BACKGROUND: Acute appendicitis is the most common condition requiring an emergency abdominal operation in childhood. In the present study, we analyzed the frequency of portal and systemic bacteremia in 42 patients with acute appendicitis and determined the microbial agents responsible for an acute appendicitis and for portal and systemic bacteremia. METHODS: Appendectomies were performed on 50 young patients (5-18 years of age), as well as clinical and bacteriological tests. Six independent samples from each patient isolated from the peripheral vein, superior mesenteric vein, appendix and peritoneum were obtained prior to surgery, during surgery and after surgery for biochemical, immunologic and bacteriologic examination. RESULTS: Pathohistology confirmed the diagnosis of appendicitis in 42 patients, while in the other eight patients there were no obvious pathologic findings, so they served as a control group. Of 50 patients with a clinical appearance of acute appendicitis, in 19 patients (38%) we detected portal bacteremia in the mesenteric vein, while in only three cases (6%) did we find systemic bacteremia detected from the peripheral vein. Furthermore, bacteriologic analysis revealed that Bacteroides spp. and Escherichia coli were the predominant species isolated. CONCLUSIONS: The results presented in this paper suggests that portal bacteremia did not influence peripheral blood reactions. Furthermore, in the present study we have found a positive correlation between the smear and bacteremia of the superior mesenteric vein, but not with the bacteremia of systemic blood.     

“Get up,shut up and stop being a fanny”: Rugby Union men and their suppression of body anxiety

BackgroundResearch has shown that those men who are dissatisfied with their bodies will mask these concerns in sports practices. Accordingly, men's body dissatisfactions often go unrecognised because the practices drawn upon to conceal them are perceived as customary forms of public masculine behaviour. This paper examines whether a group of British Rugby Union men, aged 18–30 of varied ethnic origin, participating in a 1st XV Team at a British university, experience body anxieties and use rugby and health-related sports acts to overcome and conceal them. It moves away from some of the existing methods used in clinical and sociological research to examine men's body dissatisfactions as it combines collaborative visual research methods with conventional qualitative methods to examine these men's anxieties.MethodsCollaborative photography and in-depth photo-elicitation interviews were conducted with 10 men participating in an elite university Rugby Union team in the United Kingdom.ResultsThe rugby men expressed varying degrees of body anxiety and used the sport, and health-related practices, to conceal these concerns. Visual research methods combined with conventional qualitative methods made it easier for these men to verbalise their body anxieties in more intimate dimensions of the sport.ConclusionsThese findings show that these men experience body anxieties, yet there are limited intimate dimensions for these men to express them in Rugby Union, without ramifications for their masculine identity and sports performance. More research is needed to examine these dimensions as they are significant for understanding rugby men's body anxieties and the impact their relationships with other rugby men have to these concerns. The implications are that visual research methods could be used in clinical research, assessment and treatment interventions, as they might assist in encouraging other sportsmen to express these concerns.     

Surgically correctable adrenal-dependent hypertension: a report of five cases

SummaryAlthough endocrine causes of secondary hypertension are relatively uncommon, medical practitioners must maintain a high index of suspicion for them in certain categories of patients. Such patients include young individuals, those with difficult-to-treat hypertension and those presenting with symptoms, clinical signs and/or laboratory parameters well-known to be associated with Cushing's syndrome, Conn's syndrome or phaeochromocytoma.This paper reports on 5 patients identified over a 2-year period with various hormonally-active adrenal adenomas causing hypertension in an environment where, hitherto, the occurrence of these conditions was generally thought to be rare. Aspects of the patients' histories, examination and laboratory findings that drew attention to the possibility of the diagnosis in each case are highlighted, as are the confirmatory investigations and management methods used by a multidisciplinary team of medical practitioners. The clinical outcome with appropriate treatment of adrenal-related hypertension is good and can result in significant cost savings in the long term.     

Influence of the restorative procedure factors on stress values in premolar with MOD cavity: a finite element study

In order to investigate the influence of cusp reduction, cavity isthmus width, and restorative material on stress values in premolar with mesio-occlusal-distal (MOD) cavity, numerical simulations were done on three-dimensional (3D) models of a maxillary second premolar designed using computerized tomography (CT) scan images. The use of four restorative materials (direct resin composite, direct resin composite with resin-modified glass-ionomer cement as the base, indirect resin composite, ceramic), three cavity preparation designs (without cusp coverage, 2-mm palatal cusp coverage, 2-mm palatal and buccal cusp coverage), and two cavity isthmus widths (1/2 and 2/3 intercuspal width) were simulated. After applying a static load of 200 N on the occlusal surface of the tooth, von Mises stresses in the enamel, dentin, and restoration were calculated using finite element analysis (FEA). Stress values in the enamel were primarily influenced by cavity preparation design, while restorative material showed higher contribution in dentin. The lowest stress values were obtained in models with cusp coverage and indirect restorations. Cavity isthmus width had minimal influence on stress values in tooth structures. None of the investigated factors determined stress values in the restoration. In conclusion, the use of ceramic restoration covering both palatal and buccal cusp provided the most favourable stress distribution of premolars with MOD cavity.

Patterns of internet use and mental health of high school students in Istria County,Croatia: cross-sectional study

Aim

To examine associations between different forms of internet use and a number of psychological variables related to mental health in adolescents.

Methods

A cross-sectional survey was carried out on a representative sample of students (N = 1539) from all high schools in the region of Istria in Croatia (14-19 years). The associations between four factors of internet use and nine mental health indicators were analyzed using canonical correlation analysis.

Results

The four canonical functions suggested a significant association between different types of internet use and specific indicators of mental health (P < 0.001). Problematic internet use, more typical among boys, was associated with general aggressive behavior and substance abuse (P < 0.001). Experiences of harassment, more typical among girls, were associated with health complaints, symptoms of depression, loneliness, and fear of negative evaluation (P < 0.001). Using the internet for communication and entertainment was associated with better relationships with peers (P < 0.001), while use of the internet for academic purposes was associated with conscientiousness (P < 0.001).

Conclusion

The results suggest that different patterns of internet use are significantly associated with specific sets of positive and negative mental health indicators. The data support the assumption that internet use can have both positive and adverse effects on the mental health of youth.New technologies, and especially the use of computers and the internet, are part of the everyday lives of young people and have a significant impact on their psychological development. Indeed, this mass use of new media technologies presents parents and society with a challenge to protect and support the positive development of children and youth. To date, a number of studies have examined the positive and negative aspects of using internet technologies.Literature points to several positive aspects of internet use (1,2): for information acquiring, communication, and social networking, entertainment, and online shopping. More specifically, adolescents use the internet as a useful source of information about school assignments, daily events, interests and hobbies, or health and sexuality concerns. In these instances, online activities aimed at connecting with peers have a significant place. Visiting social networking sites and using communication tools such as email, chat, forums, and discussion groups enables the creation of friendships and social groups and contributes to the development of personal identity (3). The use of computers and the internet (cyberspace) has also been argued to provide opportunities for new and faster learning, exercising one''s self-control, considering different opinions, expressing one''s attitudes and tolerance, and developing skills in critical thinking and decision-making (4). Best et al (5) found that use of online communication technologies contributed to increased self-confidence, better perception of social support, greater social capital, positive experimenting with one’s own identity, and greater opportunities for open self-disclosure. Conversely, adolescents who do not use the internet might trail behind in the development of such positive attitudes and traits and risk being rejected by their peers (6). Finally, Livingstone et al (7) found that a certain amount of risk exposure was useful in building resilience.In contrast to these positive influences of internet use, harmful effects of internet abuse range from exposure to inappropriate sexual content, pornography, and violence (2,7) to humiliation and cyber-bullying (6,8-10) and internet addiction (11,12). Research has confirmed the link between internet abuse and social isolation, depression and, anxiety (1,5,13,14), alcohol and drug abuse and gambling (15), and problems with physical health (16). Ybarra and Mitchell (17) found a connection between experiences of threats or humiliation in the virtual world and absences from school, lower school achievement, substance use disorders, delinquency and depression. Fekkes et al (18) point to the association between victimizing experiences and a number of physical, emotional, and behavioral problems, such as headaches, tension, fatigue, loss of appetite, enuresis, and sleeping problems. Slonje and Smith (19) define such experiences as a product of cyber-bullying and argue that this can be viewed as another form of aggressive behavior. Gender has emerged as a significant predictor of the manner in which the internet is used. Specifically, girls tend to experience victimizing experiences, while boys more frequently demonstrate antisocial behavior (20,21).Although many studies have identified both positive and negative correlates of internet use, there have been only a few studies using complex multivariate analyses to identify broader patterns of internet use and adolescent mental health (22,23). Less is known about how adolescents exhibiting different personalities and different emotional and behavioral patterns engage in internet use and what might be the consequences of this engagement. The aim of this study was to determine the specific patterns of internet use and mental health among adolescents. The following hypotheses were tested:H1: Problematic internet use is associated with externalized symptoms and other negative indicators of mental health. Exposure to victimizing and disturbing content on the internet is associated with internalized symptoms and negative indicators of mental health.H2: Prosocial internet use (aimed at connecting with peers and entertainment) and internet use for school purposes are associated with positive aspects of mental health.H3: Problematic internet use is present more often in young men, while exposure to disturbing content on the internet is more frequently experienced by young women.
