The association of celebrity worship with problematic Internet use, maladaptive daydreaming, and desire for fame
Authors: Zsila Ágnes , McCutcheon Lynn E. , Demetrovics Zsolt 
Published: October 2018

Background and aims
Celebrity worship, defined as an obsessive fascination with a famous person, has been associated with several mental health problems, such as symptoms of depression and anxiety, dissociation, and body image concerns. The aim of this study was to extend the scope of investigation of previous research on psychological correlates by exploring the association of celebrity worship with compulsive behaviors, such as problematic Internet use, maladaptive daydreaming, desire for fame, and self-efficacy.

Methods
A voluntary sample of 437 Hungarian adolescents and adults (78.3% male; Mage = 24.7 years, SD = 7.4) completed an online questionnaire focusing on attitudes toward celebrities and other relevant variables.

Results
As a result of hierarchical regression analyses, high levels of celebrity worship were associated with problematic Internet use, maladaptive daydreaming, and desire for fame. Furthermore, females were at higher risk to become obsessed with celebrities than males.

Discussion and conclusion
These findings provide with a more comprehensive picture of psychological difficulties associated with celebrity worship and may contribute to a better understanding of this phenomenon.
The relationship between sexual sensation seeking and problematic Internet pornography use: A moderated mediation model examining roles of online sexual activities and the third-person effect

Published: October 2018

Background and aims
Internet pornography consumption is prevalent among college students and problematic for some, yet little is known regarding the psychological constructs underlying problematic Internet pornography use (PIPU). Drawing on the Interaction of Person-Affect-Cognition-Execution model, this study tested a model that sexual sensation seeking (SSS) would impact PIPU through online sexual activities (OSAs) and that this relationship would be influenced by the third-person effect (TPE; a social cognitive bias relating to perceived impacts on others as compared to oneself) in a gender-sensitive manner.

Methods
A total of 808 Chinese college students (age range: 17–22 years, 57.7% male) were recruited and surveyed.

Results
Men scored higher than women on OSAs and PIPU and on each scale’s component factors. The relationship between SSS and PIPU was mediated by OSAs, and the TPE moderated this relationship: the predictive path (SSS to PIPU) was significant only in participants with high TPE. The moderated mediation model was not invariant across gender groups, with data suggesting that it accounted for a greater proportion of the variance in men as compared with women.

Discussion and conclusions
The findings suggest that SSS may operate through participation in OSAs to lead to PIPU, and this relationship is particularly relevant for college-aged males scoring high on the TPE. These findings have implications for individuals who might be particularly vulnerable to developing PIPU and for guiding educational efforts and targeting interventions in college-aged students. The extent to which these findings extend to other age groups and cultures warrants further examination.
Pathological buying symptoms are associated with distortions in judging elapsed time
Authors: Nicolai Jennifer , Moshagen Morten 
Published: October 2018

Background and aims
Pathological buying (PB) is often assumed to be related to deficits in impulse control. Distortions in judging elapsed time are one component of behavioral impulsivity. This study was set out to examine the hypothesis that PB propensity is associated with distorted time perception, such that time is perceived to pass more slowly.

Methods
The study is based on a convenience sample of 78 adults. Symptom severity of PB and related problems/disorders (substance use, borderline, depression, mania, and obsessive–compulsive disorder) as well as four dimensions of trait impulsivity were assessed. A time-production task was employed that required participants to produce prespecified time intervals ranging from 1 to 60 s.

Results
PB propensity was associated with the belief that time elapses more slowly, even when controlling for symptoms of related disorders and general trait impulsivity. Neither trait impulsivity nor symptoms of related disorders were predictive of distortions in judging elapsed time.

Discussion and conclusion
These results suggest that PB propensity is related with non-specific, general deficits in judging elapsed time as a specific component of behavioral impulsivity.

Published: October 2018

Background and aimsPast research on the classification of problematic Internet use (PIU) has focused on symptom-based severity and usage motive in order to understand its mechanism. Recently, usage context, such as family or social relationships, has been identified as a key influencing factor of PIU. Therefore, we extended the classification of PIU to include usage context in addition to symptom-based severity and usage motive.MethodsTo classify PIU types, we conducted two studies. First, we performed a clustering analysis, where 265 counseling cases were clustered into usage types in terms of motive and context. After characterizing each usage type, we examined their hierarchical relationships by considering symptoms. Second, we performed a focus group interview with six counselors to increase the transferability of usage types. This transferability was established by matching counselors’ quotations to the usage types. When usage types showed consistency between quotations and the clustering analysis, we identified the progression patterns between hierarchical relationships.ResultsThe clustering analysis of motive and context yielded six usage types with three hierarchical relationships. The focus group interview results verified the transferability of these six types and identified two progression patterns between the hierarchical relationships.Discussion and conclusionAlthough usage motive and context were given equal weight before the clustering analysis, the resulting types revealed that usage context played a greater role in the classification process.
Lower occlusion pressure during resistance exercise with blood-flow restriction promotes lower pain and perception of exercise compared to higher occlusion pressure when the total training volume is equalized

Published: October 2018

Low-intensity resistance exercise with blood-flow restriction (BFR) promotes similar adaptations to high-intensity resistance exercise (HI-RE). Interestingly, BFR has been demonstrated to be effective for a wide range of occlusion pressures. However, the occlusion pressure magnitude may alter the psychophysiological stress related to BFR as measured by rating of perceived exertion scale (RPE) and rating of pain. We aimed to compare the RPE and pain levels across different magnitudes of occlusion pressures, promoting new knowledge regarding occlusion pressure on stress related to BFR. All BFR protocols ranging between 40% and 80% of total arterial occlusion (BFR40, BFR50, BFR60, BFR70, and BFR80) were compared to HI-RE in 12 participants using a randomized and crossover design 72 h apart. BFR protocols and HI-RE were performed with 30% and 80% of one-repetition maximum (1RM) test value, respectively. RPE and pain levels were measured before exercise and immediately after each set. BFR protocols (i.e., BFR40 and BFR50) presented overall lower RPE response compared to higher-pressure BFR (i.e., BFR70 and BFR80) and HI-RE conditions. For pain levels, low-pressure BFRs (i.e., BFR40 and BFR50), and HI-RE showed lower values than high-pressure BFR protocols (i.e., BFR60, BFR70, and BFR80). In conclusion, low-pressure BFR protocols promote lower RPE and pain compared to high-pressure BFR protocols (between 60% and 80% of occlusion pressure), when total training volume (TTV) is equalized. In addition, HI-RE promotes similar levels of pain, but higher RPE than low-pressure BFR, probably due to the higher TTV.
Stigma of substance use in healthcare: A research on contact hypothesis
Authors: Pfitzner K , Kapitány-Fövény M 
Published: October 2018

Introduction
Patients suffering from mental disorders and especially substance-use disorders (SUDs) are often stigmatized by both lay individuals and health professionals, which may lead to poorer treatment outcomes. The purpose of this study was to assess the level of stigma against alcohol and drug users among lay respondents and actors of healthcare.

Materials and methods
An online questionnaire was filled out by a total of 148 participants from three subgroups: (a) 25 addictology professionals, (b) 55 emergency care professionals, and (c) 68 lay individuals outside healthcare. The questionnaire contained standardized scales measuring the severity of substance use, authoritarianism, and own items assessing demographics, attitude towards substance users, and substance-related knowledge.

Results
A more accepting attitude towards drug users was explained by the respondents’ own substance use (β = 4.52, p < .01) and knowledge in addictology (β = 2.22, p = .05). Repeated encounters with substance users only showed connection with destigmatization in case of positive experiences. Emergency care professionals were characterized by the most stigmatizing attitude towards substance users.

Discussion
Our results partially support Allport’s contact hypothesis. We emphasize the need of a continuous sensitizing program targeting emergency care professionals in order to change their attitude towards SUD patients.

Published: October 2018

Abstract: The bone marrow aspiration, which was done in a leukopenic, hypochromic, microcytic, progressive anemic, thalassemic patient, revealed megaloblastic morphology. The low level of vitamin B12 and the reticulocytosis following the B12 supportation strenghtened the diagnosis of pernicious anemia. The set of the right diagnosis has been delayed by the fact that even in severe anemia one could not obtain the typical signs of B12 deficiency, having a hypochromic, microcytic erythrocyte morphology, due to the thalassemia minor disorder.

Abstract: Introduction: Mortality of prostate carcinoma can be significantly decreased by the use of modern diagnostic and therapeutic options. Patients in early stages can be cured by radical surgery or radiotherapy. Aim: Overview and comparison of previous and present diagnostic and therapeutic methods regarding accuracy of diagnosis, improvement of efficiency and decrease of toxicities. We also aimed to explore general correlations in case of serious complications. Method: By the help of two prostate cancer patients we demonstrate the importance of accuracy and change of histological diagnosis, significance of proper imaging techniques, and also show parameters of conventional and modern radiotherapy and their acute and chronic complications. Differences of previous and present methods and their consequences were analyzed. Results: By now, histological findings in the patients’ diagnosis have changed. Both patients received conventional three-dimensional definitive radiotherapy in 2009–2011, and their prostate cancer was cured. In one case, urinary bladder also received radiotherapy because prostate carcinoma had infiltrated it. In the other case, the contemporary radiotherapy involved urinary bladder’s fundus due to safety margins. Although acute grade 2 cystitis developed in both cases and recovered in several weeks, as late complication bladder shrinkage developed, which after the ineffectiveness of conventional therapies had to be cured by radical cystoprostatectomy – in order to cease bleeding and to cure incontinence. Conclusions: In case of prostate carcinomas, serious complications can be avoided by the improvement of diagnostic and therapeutic options. Synthesis of data could be more successful if they were analyzed in the light of previous experiences. Orv Hetil. 2018; 159(32): 1317–1325.

Abstract: Introduction: At the end of 2016, the number of patients on the domestic transplant waiting list was twice as much as the number of the organ transplantations accomplished that year. The institutional prerequisites for functional organ donation programs are the sufficient number of personnel and the adequate material conditions to be provided in relation to the needs. Aim: The goal of the current study was to evaluate the professional environment in Hungary. Method: The Organ Coordination Office at the Hungarian National Blood Transfusion Service compiled a questionnaire survey on the personnel and material conditions of the intensive care units (ICUs) in Hungary in regards to organ donations. The survey applied an online questionnaire including 43 questions. In addition to the number of beds and employees, we investigated the tools needed for the legal and the medical diagnosis of brain death as well as the accessibility of examinations on the donor information form. The data collection spanned from 12 December 2016 to 30 June 2017. Results: 59 intensive care units completed the questionnaire; the investigation involved 640 hospital beds, 816 physicians and 1252 nurses. In the daytime shift, 0.25 doctors and 0.41 nurses work on a patient bed at an average, while in the night shift, the figures are 0.11 and 0.33, respectively. 51.7% of the doctors are registered to access the National Non-Donor Registry, and brain death diagnosis committee is available in 83% of the hospitals. Among the medical imaging methods (cranial, abdominal-thoracic), CT scan in 71–73%, abdominal ultrasound in 75%, transthoracic echocardiograpy (TTE) in 37%, transoesophageal echocardiography (TEE) in 4%, bronchoscopy in 49%, coronarography in 19% are non-stop available, with instant interpretation in 75% of the cases. Transcranial Doppler (TCD) in 30%, four-vessel angiography in 45% and SPECT in 14% of the cases are available. More than 90% of the laboratory examinations on the donor information form are available 24 hours a day. Conclusion: The number of doctors and nurses did not change compared to our 2008 survey (0.18 doctors, 0.37 nurses/ICU beds in 2008), but the care of potential donors needs more resources and time. The standby availability of personnel and material conditions is a prerequisite for organ donation programs in order to save lives. Orv Hetil. 2018; 159(33): 1360–1367.

Abstract: Introduction: The continuous monitoring of quality indicators in gastrointestinal endoscopy has become an essential requirement nowadays. Most of these data cannot be extracted from the currently used free text reports, therefore a structured web-based data-collecting system was developed to record the indicators of pancreatobiliary endoscopy. Aim: A structured data-collecting system, the ERCP Registry, was initiated to monitor endoscopic retrograde cholangiopancreatography (ERCP) examinations prospectively, and to verify its usability. Method: From January 2017, all ERCPs performed at the First Department of Medicine, University of Pécs, have been registered in the database. In the first year, the detailed data of 595 examinations were entered into the registry. After processing these data, the testing period of the registry is now finished. Results: On 447 patients, 595 ERCPs were performed. The success rate of cannulation is 93.8% if all cases are considered. Difficult biliary access was noted in 32.1% of patients with native papilla, and successful cannulation was achieved in 81.0% of these cases during the first procedure. Post-ERCP pancreatitis was observed in 13 cases (2.2%), clinically significant post-papillotomy bleeding was registered in 2 cases (0.3%), while 27 patients (4.5%) developed temporary hypoxia during the procedure. 30-day follow-up was successful in 75.5% of the cases to detect late complications. All of the quality indicators determined by the American Society of Gastrointestinal Endoscopy (ASGE) were possible to monitor with the help of the registry. Our center already complies with most of these criteria. Conclusions: Continuous monitoring of the quality indicators of endoscopic interventions are not supported by the current hospital information system but it became possible with our registry. The ERCP Registry is a suitable tool to detect the quality of patient care and also useful for clinical research. Several endoscopy units have joined already this initiative and it is open for further centres through our web page ( https://tm-centre.org/hu/regiszterek/ercp-regiszter/ ).

Abstract: Introduction: Nowadays ever smaller, sub-centimetre lung nodules are screened and diagnosed. For these, minimally invasive resection is strongly recommended both with diagnostic and therapeutic purpose. Aim: Despite many advantages of minimally invasive thoracic surgery, thorough palpation of the lung lobes and thus the localization of lung nodules are still limited. There are several options to solve this problem. From the possibilities we have chosen and tried wire- and isotope-guided lung nodule localization. Materials and methods: In 2017, at the Thoracic Surgery Department of the National Institute of Oncology we performed wire- and isotope-guided minimally invasive pulmonary nodule resection in five patients. The diameter of the lung nodules was between 0.5 and 1.2 cm. The age of the patients was between 44 and 65 years and none of them had severe comorbidities, which meant low risk for complications. Results: We successfully performed the minimally invasive atypical resection in all cases. After the wire and isotope placement we found a 2–3 mm pneumothorax in one patient that did not need urgent drainage. In another patient we found that high amount of intraparenchymal bleeding surrounded the channel of the wire. During the operation, two wires were displaced when the lung collapsed, and in another case the mentioned bleeding got into the thoracic cavity and made it difficult to detect the nodule. In one case we resected the wire-guided lung tissue, but the isotope-guided lung nodule was below the resection line. Conclusion: Both techniques could help to localize the non-palpable lung nodules. Based on our initial experiences, the isotope-guided method provides more details to estimate the exact depth of the nodule from the visceral surface of the pleura and we can avoid the unpleasantness of wire displacement. On the other hand, the production of the isotope requires a more developed infrastructure and the exact timing of the operation after the isotope injection is more strict.

Abstract: Introduction: In a clinicopathological retrospective epidemiological study we investigated benign tumors and tumor-like lesions located in the orofacial region, diagnosed at the Universiy of Szeged, Department of Oral Medicine. Method: During a 54-year period (1960–2014), 14 661 biopsies were taken. The included subjects were 7491 patients diagnosed with benign tumors and tumor-like lesions. Results: The average age of patients was 55.3 years, 2823 (37.7%) patients were male and 4668 (62.3%) female. The male : female ratio was 1 : 1.65. Most of the patients included in the study were aged 51–60 (1280, 17.1%). The number of children was 1014 (13.6%) and the number of adults was 6477 (86.3%). The number of non-neoplasms was 6420 (85.7%), being significantly higher than the number of neoplasms (1071, 14.3%). Most of the lesions were of mesenchymal origin (5574, 77.4%); the number of lesions of non-mesenchymal origin was 982 (13.1%). The most prevalent type of lesions was traumatic fibroma (fibrosis): 1806 (32.4%). The most common lesion type in the group of lesions of infectious/inflammational origin was pyogenic granuloma, the number of which was 465 (8.3%). The most common cystic lesion was mucocele (805, 10.7%). Hemangioma was the most frequent lesion type among developmental anomalies with the number of 815 (14.6%). The most common location of the lesions was the lip in 2081 cases (27.8%), followed by the gingiva in 2024 cases (27.0%), bucca in 1069 cases (14.3%), tongue in 981 cases (13.1%), and the facial skin in 695 cases (9.3%). After taking biopsy, the majority of benign lesions were treated with cryo-, laser-, or combined (cryo and laser) surgery. Conclusion: The present computer-aided study showed that irritational fibroma was the most common orofacial benign tumor, and the lip was the most frequent location. The diagnostic classification and the methodology are considerably different in the majority of the studies, which may hinder the exact comparison with other surveys from different regions of the world.
