Proneness to Alcohol use Disorder or Pathological Gambling as Differentially Determined by Early Parental and Personality Factors.

Owing to growing alcoholism and gambling, numerous variables have been the subject of study to better understand the causes of such addictions. This study aims to investigate personality factors, parental styles in upbringing and early exposure to alcoholism integratively to shed light on how such variables generally shape vulnerability for addictive behaviours and alcohol use disorder (AUD) as well as pathological gambling (PG), separately. The sample consisted of 150 for the inpatient groups (78 AUD and 72 PG) and 102 participants for the control group. The inpatient group comprised "pure" AUD (excluding gambling and other significant addictive disorders) and "pure" PG (excluding AUD and other significant addictive disorders). A random forest-trees analysis established a model accurately classifying 79% of participants from the addictive group and found low conscientiousness, an authoritarian father, a less-flexible mother and neuroticism to be predisposed factors for both addictions. Additionally, through structural equation modeling, a satisfying-index model shows higher extroversion and lower openness may be attributed to PG, as well as the father's authoritarian parenting style. The mother's authoritarian or permissive styles may be linked to AUD and the father's alcoholism. The research concludes AUD and PG have similarities in personality as vulnerable factors for addictive behaviours as well as essential differences in personality and early experiences from boundaries set by mothers and fathers and alcoholism in childhood. The results are applicable in preventive programs as well as working with patients and their parents to create more individualized treatment in relation to addiction type.

Contrasting Effects of Pressure Compensation on TEOAE and DPOAE in Children With Negative Middle Ear Pressure.

In children with normal cochlear acuity, middle ear fluid often abolishes otoacoustic emissions (OAEs), and negative middle ear pressure (NMEP) reduces them. No convincing evidence of beneficial pressure compensation on distortion product OAE (DPOAE) has yet been presented. Two studies aimed to document effects of NMEP on transient OAE (TEOAE) and DPOAE. In Study 1, TEOAE and DPOAE pass/fail responses were analyzed before and after pressure compensation in 50 consecutive qualifying referrals having NMEP from -100 to -299 daPa. Study 2 concentrated on DPOAE, recording both amplitude (distortion product amplitude) and signal-to-noise ratio (SNR) before and after pressure compensation. Of the 20 participants, 5 had both ears qualifying. An effect of compensation on meeting a pass criterion was present in TEOAE for both left and right ear data in Study 1 but not demonstrable in DPOAE. In Study 2, the distortion product amplitude compensation effect was marginal overall, and depended on recording frequency band. SNR values improved moderately after pressure compensation in the two (overlapping) sets of single-ear data. In the five cases with both ears qualifying, a stronger compensation effect size, over 3 dB, was seen. The absolute dependence of SNR on frequency was also strongly replicated, but in no analysis, the frequency × compensation interaction was significant. Independent of particular frequency range, the data support a limited SNR improvement in 2 to 3 dB for compensation in DPOAE, with slightly larger effects in ears giving SNRs between 0 dB and +6 dB, where pass/fail cutoffs would generally be located.

Phenotypes of organ involvement in sarcoidosis.

Sarcoidosis is a highly variable, systemic granulomatous disease of hitherto unknown aetiology. The GenPhenReSa (Genotype-Phenotype Relationship in Sarcoidosis) project represents a European multicentre study to investigate the influence of genotype on disease phenotypes in sarcoidosis.The baseline phenotype module of GenPhenReSa comprised 2163 Caucasian patients with sarcoidosis who were phenotyped at 31 study centres according to a standardised protocol.From this module, we found that patients with acute onset were mainly female, young and of Scadding type I or II. Female patients showed a significantly higher frequency of eye and skin involvement, and complained more of fatigue. Based on multidimensional correspondence analysis and subsequent cluster analysis, patients could be clearly stratified into five distinct, yet undescribed, subgroups according to predominant organ involvement: 1) abdominal organ involvement, 2) ocular-cardiac-cutaneous-central nervous system disease involvement, 3) musculoskeletal-cutaneous involvement, 4) pulmonary and intrathoracic lymph node involvement, and 5) extrapulmonary involvement.These five new clinical phenotypes will be useful to recruit homogenous cohorts in future biomedical studies.

Administering the Sarcoidosis Health Questionnaire to sarcoidosis patients in Serbia.

OBJECTIVE: The aim of this study was to use a Serbian-language version of the disease-specific, self-report Sarcoidosis Health Questionnaire (SHQ), which was designed and originally validated in the United States, to assess health status in sarcoidosis patients in Serbia, as well as validating the instrument for use in the country. METHODS: This was a cross-sectional study of 346 patients with biopsy-confirmed sarcoidosis. To evaluate the health status of the patients, we used the SHQ, which was translated into Serbian for the purposes of this study. We compared SHQ scores by patient gender and age, as well as by disease duration and treatment. Lower SHQ scores indicate poorer health status. RESULTS: The SHQ scores demonstrated differences in health status among subgroups of the sarcoidosis patients evaluated. Health status was found to be significantly poorer among female patients and older patients, as well as among those with chronic sarcoidosis or extrapulmonary manifestations of the disease. Monotherapy with methotrexate was found to be associated with better health status than was monotherapy with prednisone or combination therapy with prednisone and methotrexate. CONCLUSIONS: The SHQ is a reliable, disease-specific, self-report instrument. Although originally designed for use in the United States, the SHQ could be a useful tool for the assessment of health status in various non-English-speaking populations of sarcoidosis patients.

Precision-scored parental report questions and HL-scaled tympanometry as informative measures of hearing in otitis media 1: Large-sample evidence on determinants and complementarity to pure-tone audiometry.

INTRODUCTION: In otitis media with effusion (OME), hearing loss is a core sign/symptom and basis of concern, with absolute pure-tone threshold sensitivity (in dB HL) by air-conduction providing the default measure of hearing. However several fundamental problems limiting the value of HL measures in otitis media are insufficiently appreciated. To appraise the joint value and implications of multiple hearing measures towards more comprehensive hearing assessment in OM, we examine in two related articles the interrelations and common or diverging determinants of three measures, two of them objective: binaural HL, and ACET (the published quasi-continuous scaling of binaural tympanometry to HL). The third measure is partly subjective: parentally reported hearing difficulties (RHD-4); this is the precision-scored total of the 4 items selected for the OM8-30 general purpose questionnaire for parents in OM. METHODS: The Eurotitis-2 study (Total N=2886) internationally standardises OM8-30 and its OMQ-14 short form. The clinical and parent-response variables acquired cover many issues in diagnosis, symptomatology and impact of OM. Data acquisition was built upon routine clinic practice, enabling us also to document some properties of that practice, such as patterns of missing HL data. To address possible confounding or loss of representativeness from this, we investigated the implications of substituting tympanometry-based ACET for missing HL to give an HL/ACET hybrid. ACET is the mapping of categorical tympanometry to continuous HL. We simulated degrees of artificial missingness of HL up to 35% on the 1430 complete-data cases, using random deletion, with 1000-version bootstrapping. Correlations of this HL/ACET hybrid with pure (100%) HL then documented the degree of correlation retained under dilution of HL by an admixture of ACET; we also documented distribution shapes. For RHD-4, we then probed the determining influences on severity of score as an auditory disability measure, both background ones (from centre, age, sex, socio-economic status, length of history, diagnosis and season) and the two underlying objective hearing measures (HL, ACET). We ran these multiple regressions (GLMs), for representativeness and generality, both on 1430 complete-data cases (i.e. all 3 hearing variables present) and also on supplemented samples according to data required only for particular analyses (N increased by +56% to +68%). A further method of sample supplementation (by up to +96%) used the HL/ACET hybrid. RESULTS: Sex made negligible difference in any analysis. The particular collaborating centre, age, season and diagnosis collectively influenced presence/absence of HL data very strongly. (Area under ROC 0.944). Socio-economic status did not influence HL presence; surprisingly, nor did RHD, ACET or length of history, after control for centre, age, diagnosis and season. Of the inter-correlations between hearing measures, only the one between ACET and RHD was influenced (slightly reduced) by the inclusion of cases without HL data. In the simulated substitutions, Pearson correlation of hybrid HL/ACET with true HL remained above 0.90 for substitution by ACET of up to 30% rate of artificially 'missing' HL. Centre differences were adequately summarised by simple absolute additive differences in mean local case severity. In the determinant models for RHD on the 1430 complete-data cases, HL and the set of background determinants collectively explained broadly similar proportions of RHD's variability, totalling 36.8% explained. On the larger maximum case samples, slightly less absolute variability was explicable than on complete-case data, but relative magnitudes of contribution from individual determinants, both background and hearing measures, remained similar. The expected mean differences in RHD between diagnoses (RAOM, OME, and combined) were found, but the patterns of background and objective measure influences determining RHD did not differ significantly between the diagnoses. CONCLUSIONS: (1) In the Eurotitis-2 database, descriptive differences in various background demographic and clinical measures between cases on whom HL data were obtained versus not, were only of material magnitude for length of history and reported hearing difficulties. Such descriptive differences are not necessarily bases of confounding, so using our framework of 6 background adjuster variables, (particular collaborating centre, age, season, diagnosis, socioeconomic status and length of history) we isolated the determinants of HL data presence. The first four listed strongly predicted HL data presence/absence so are sufficient to control analyses well for any bias or confounding by HL data presence. (2) Diagnoses as OME and combined (OME+RAOM) had higher probability of HL data being present relative to RAOM, indicating that HL acquisition is chiefly seen as confirming and quantifying hearing loss in (suspect) OME, not as ruling it out (e.g. in suspected RAOM). Given this, also using RHD and or ACET as pre-triage to efficiently target capacity and/or reduce costs and opportunity costs of acquiring HL would be rational, but there was no evidence of such precise use of initial hearing-related information to decide on HL acquisition. (3) The full six background variables explained comparable variance in Reported Hearing Difficulties (RHD) to what was explained by ACET, but not quite as much as by HL. Achieving a high percentage explained (32-37% from good models) required both classes of determinant to be entered as predictors. The pattern of background determining influences for RHD was largely stable, with or without objective measures as additional predictors, and on maximum or complete-data cases. Length of history strongly determines RHD for a given concurrent HL. (4) Accepting ACET as substitute where HL was missing in OM cases gave a sample-size enhancement of 17% in Eurotitis-2, with negligible difference in the pattern of determinants. This hybrid measure can be recommended as reasonable next-best when moderate percentages of HL data are missing. (5) The stable pattern of prediction of RHD suggests that our six background determinants provide a very promising low-cost yet comprehensive framework for determination. It hence offers pluripotent statistical adjustment against confounding, applicable to RAOM, OME and combined diagnoses in any analysis using this database. Claims that it thereby offers a sufficient framework for full European standardisation of all the scores from the OM8-30 questionnaire measures await parallel demonstrations for symptom areas other than RHD. As 25% of the variance in RHD severity can be explained by the six adjusters in our framework, none of the six variables should be omitted from acquisition and analytic use in future OM research.

Verifying Sarcoidosis Activity: Chitotriosidase versus ACE in Sarcoidosis - a Case-control Study.

BACKGROUND: Until now, a proper biomarker(s) to evaluate sarcoidosis activity has not been recognized. The aims of this study were to evaluate the sensitivity and specificity of the two biomarkers of sarcoidosis activity already in use (serum angiotensin converting enzyme - ACE and serum chitotriosidase) in a population of 430 sarcoidosis patients. The activities of these markers were also analyzed in a group of 264 healthy controls. METHODS: Four hundred and thirty biopsy positive sarcoidosis patients were divided into groups with active and inactive disease, and groups with acute or chronic disease. In a subgroup of 55 sarcoidosis patients, activity was also assessed by F-18 fluorodeoxyglucose positron emission tomography (18F-FDG-PET) scanning. Both serum chitotriosidase and ACE levels showed non-normal distribution, so nonparametric tests were used in statistical analysis. RESULTS: Serum chitotriosidase activities were almost 6 times higher in patients with active sarcoidosis than in healthy controls and inactive disease. A serum chitotriosidase value of 100 nmol/mL/h had the sensitivity of .5% and specificity of 70.0%. A serum ACE activity cutoff value of 32.0 U/L had the sensitivity of 66.0% and the specificity of 54%. A statistically significant correlation was obtained between the focal granulomatous activity detected on 18F-FDG PET/CT and serum chitotriosidase levels, but no such correlation was found with ACE. The levels of serum chitotriosidase activity significantly correlated with the disease duration (P < 0.0001). Also, serum chitotriosidase significantly correlated with clinical outcome status (COS) categories (ρ =0.272, P =0.001). CONCLUSIONS: Serum chitotriosidase proved to be a reliable biomarker of sarcoidosis activity and disease chronicity.

Fatigue in sarcoidosis: detection and treatment.

Fatigue is a prominent symptom in a large number of medical conditions, malignant and infectious diseases. Fatigue is also a prominent symptom of sarcoidosis. The occurrence of fatigue in sarcoidosis is well known but exact incidence has not been established and varies from 30-70% of patients depending on age, sex and organ involvement by the granulomatous process. The exact definition of fatigue varies broadly. It can be both physical and mental. The patients describe their sensation of fatigue qualitatively different from that fatigue they experienced before they became sick. Fatigue has a major impact on the quality of life in sarcoidosis. Establishing the extent of fatigue in sarcoidosis provides relevant insight regarding the patient's quality of life. Unfortunately there is no objective parameter for assessing fatigue in sarcoidosis. Generally, fatigue is detected by means of questionnaires. Regarding the therapy, there is no effective treatment for fatigue in sarcoidosis.

Evaluation of the role of pathology in the diagnosis and differential diagnosis of pulmonary and extrapulmonary sarcoidosis.

UNLABELLED: INTRODUCTION; Sarcoidosis is a multisystem, granulomatous disease of unknown etiology. Sarcoid granulomas appear as immunological response to a particular but still unknown agent of the human body. OBJECTIVE: The main purpose of this study was to point out the important fact that the exact diagnosis of sarcoidosis must be estimated by clinical and pathological correlation, and team cooperation between the clinician and the pathologist. METHODS: Of 751 patients referred with the suspected diagnosis of sarcoidosis, from 1995 to 1999, 663 (431 female and 232 male) were analyzed and confirmed as having sarcoidosis stage I-III based on biopsy findings obtained by bronchoscopy, open lung biopsy, skin biopsy, liver biopsy or splenectomy. RESULTS: Diagnosis of sarcoidosis was made in 663 patients, 431 females and 232 males (ratio 1.9:1). The average age of patients varied from 16 to 67 years, with those below age 50 years being predominant (78.4%). The highest number of patients was diagnosed in stage I of lung sarcoidosis (81.7%). Sarcoidosis was the most common cause of hilar and mediastinal lymphadenopathy (72.2%). CONCLUSION: Biopsy is a necessary diagnostic procedure for pathological diagnosis of sarcoid granuloma before treatment even in patients where clinical, radiological, biochemical and immunological tests imply the diagnosis of sarcoidosis.

[Clinical evaluation of eustachian tube transience and function in patients with different types of increased nasal resistance].

BACKGROUND/AIM: Eustachan tube is a connection between throat and the middle ear. Inflammatory processes and malformations of nasal cavity could lead to dysfunction of the whole upper respiratory tract, thas emphasizing the evaluation of the Eustachian tube function both in surgery and in medicine in general. The aim of this study was to evaluate the Eustachian tube passage and function by tympanometry in different types of nasal resistance. METHODS: Eustachian tube passage and function was tested in 102 patients with different types of nasal pathology and nasal resistance and compared to the results of 41 healthy persons with normal values of nasal resistance included in the control group. The patients with nasal pathology were divided into three subgroups: with mechanical, inflammatory and mixed alterations. Nasal resistance was carried out with constant body plethysmography (Jaeger). The test of Eustachian tube passage and function was performed using tympanometric Toynbee-deglutition/Valsalva-deglutition test. The results of measurements were compared with those in the healthy control group and analyzed by means of parametric and nonparametric statistic tests, Pearson chi2 test, Fisher test of exact probability and variance analysis. RESULTS: The subgroup with inflammatory alterations had significantly higher values of pathological tympanograms than other subgroups and the control group (p < 0,05). The dysfunction of the Eustachian tube was significantly more present in all subgroups than in the control group (p < 0,05). CONCLUSION: Pathological form of tympanograms is more often present in purely inflammatory changes of nasal cavities with higher nasal resistance than in mechanical nasal obstruction. All forms of higher nasal resistance are more often accompanied with Eustachian tube dysfunction. There was no significant differences in Eustachian tube passage between the subgroups and the control group.

[Chronic sarcoidosis].

INTRODUCTION: According to available literature data, chronic pulmonary and extrapulmonary sarcoidosis occurs in 10-30% of all sarcoidosis patients. Unpredictable course of the disease is a great challenge for scientists and researchers. Clinical and biological parameters for evaluation and prediction of the course of the disease are still the topic of different scientific investigations all over the world. According to an American case control study on sarcoidosis, unique diagnostic criteria have been established in order to simplify the diagnosis of sarcoidosis. The aim of this study was to present the morbidity and the clinical course of sarcoidosis in our patients. MATERIALS AND METHODS: We analyzed 370 sarcoidosis patients and confirmed the diagnosis of sarcoidosis by biopsy of the suspected granuloma, and by excluding any other possible cause of granulomatous inflammation. In our analyzed patients with sarcoidosis, chronic form was diagnosed in about 30%. An extremly unpredictable, chronic form of the disease was established in patients with extrapulmonary localisations (heart, CNS, liver and bones). CONCLUSION: Follow-up criteria and control examinations of sarcoidosis patients are suggested as well.

[Sarcoidosis and diabetes: therapeutic aspects].

FIRST CASE: A 45-year-old female patient with diabetes was on corticosteroid therapy for a year due to pulmonary sarcoidosis. During the last six years she was treated with oral antidiabetic drugs, but during the last couple of months, she required insulin therapy due to impaired glycoregulation. After corticosteroid therapy was discontinued, glycoregulation improved and insulin therapy was discontinued as well. SECOND CASE: a 32-year-old male patient was on prednisolone therapy due to pulmonary and extrapulmonary sarcoidosis. A few weeks later diabetes mellitus (de novo) was established. During the treatment of sarcoidosis with corticosteroids, short-term insulin therapy was due to impaired glycoregulation. Insulin therapy has improved the glycoregulation. DISCUSSION: There is no certain evidence about the incidence of diabetes mellitus under the influence of corticosteroids, due to increase of hepatic glucose production, insulin resistance and exhaustion of pancreatic beta-cells because of stimulated endogenous secretion. During treatment of sarcoidosis, corticosteroid therapy may cause deterioration of glycoregulation and occurrence of clinically manifested diabetes mellitus in patients with impaired glycose tolerance or predisposition to diabetes. CONCLUSION: Diabetic patients with sarcoidosis who need corticosteroid therapy, should control glycoregulation Patients with sorcoidosis, treated with corticosteroid therapy need regular control in order to diagnose early diabetes.

[Application of measuring instruments--quality of life questionnaires in patients with chronic sarcoidosis].

INTRODUCTION: Health-related quality of life in interstitial lung diseases, especially in sarcoidosis, has hardly received appropriate attention in clinical studies due to lack of validated methods of measurement. Until now, in patients with sarcoidosis and interstitial lung diseases, several generic and respiratory specific quality-of-life instruments were used in order to discover the most valid and reliable quality-of-life instrument. Sarcoidosis is a multi-system disease that affects quality of life in many different ways. MATERIAL AND METHODS: In this study the Sarcoidosis Health Questionnaire was used to evaluate the quality of life in sarcoidosis patients. 89 biopsy positive sarcoidosis patients were analyzed (16 male, 73 female); their mean age 46.15 +/- 11.11 years. 34 (39%) patients presented with acute sarcoidosis, 53 (61%) with chronic sarcoidosis and 46 patients (51.7%) had extrapulmonary disease. In regard to treatment, 51 (57%) patients were treated with corticosteroids 18 (20%) with methotrexate and in 20 (23%) spontaneous remission was reported. All analyses were performed using the Statistical Package for Social Science Software: A probability value less than 0.01 considered being statistically significant. RESULTS: Statistically significant correlation was found between the sarcoidosis health questionnaire scores and chronic sarcoidosis. daily 0.001, emotional 0.014 and total 0.01. In regard to treatment, significant difference between groups was found in the domain of physical (sig 0.006) emotional (sign 0.005) and total (sign 0.001) scores. CONCLUSION: The first sarcoidosis specific questionnaire shows perfect correlation with the possible clinical course in patients with sarcoidosis.

[The role of EQ5D self-classifier in assessing quality of life in patients with sarcoidosis].

INTRODUCTION: In medicine, quality of life is a very important issue. Nowdays, in our circumstances, it is an important part of diagnostic and therapeutic procedures. The aim of this study was to analyze the role of EQ5D questionnaire in patients with sarcoidosis. MATERIAL AND METHODS: EQ5D self-questionnaire was used in patients with sarcoidosis and we analyzed the obtained data. RESULTS: The analysis included patients with previously proved sarcoidosis--pulnmonary and extrapulmonary (bronchoscopy and other biopsies). All patients were treated at the Institute of Tuberculosis and Lung Diseases. We analyzed a group of 84 (19 male and 65 female) patients with average age of 45 years. Most patients had a chronic state of disease and were nonsmokers. In regard to the radiographic stage of pulmonary sarcoidosis, levels of disease activity (acute, chronic and relapse), levels of sACE, levels of sIgE, smokers--non smokers, and in regard to obtained scores, no statistically significant difference was found in examined groups, except in the group of patients with low level sIgE (score 0.276). CONCLUSION: EQ5D questionnaire is a good tool for analyzing the health status of patients with sarcoidosis, but still a more specific questionnaire should be designed for this multisystem disease.

[Analysis of patients with tuberculosis and diabetes mellitus at the Institute of Pulmonary Diseases and Tuberculosis of the Clinical Center of Serbia (2000-2002)]. / Analiza obolelih od tuberkuloze i diabetes mellitusa u Institutu za Plucne Bolesti i Tuberkulozu Klinickog Centra Srbije (2000-2002).

INTRODUCTION: Tuberculosis and diabetes mellitus are diseases that are commonly found together with adverse mutual effects. MATERIAL AND METHODS: The aim of this study was to analyze the incidence and association between tuberculosis and diabetes mellitus among TB patients hospitalized at the Institute of Pulmonary Diseases and Tuberculosis, Clinical Center of Serbia over the three-year period: 2000-2002. RESULTS: Among the tuberculous patients the average incidence of diabetes mellitus over the analyzed period was 9.8%. Most of the patients were above 55 years of age (52.8%), followed by 41.6% of middle aged (30-55 years) patients, while only a small number of patients (6.5%) belonged to the young population group (below 30). Males (64%) were more frequently affected than females (36%). Significant number of patients (61%) had a severe form of diabetes mellitus with frequent glycoregulation disorders necessitating either short-term or permanent insulin therapy. Analysis of clinical forms of tuberculosis at the time of detection revealed that 50% of patients had a moderately disseminated form of the disease with bilateral changes while the other 50% had a disseminated form. The average bacillarity was 56%. Radiological findings of tuberculosis in diabetics was manifested atypically in the lower pulmonary fields with bronchopneumonic shadows found in 11.1% of patients. CONCLUSION: Tuberculosis presents with changed clinical and radiological pictures in considerable number of diabetics, particularly elderly ones, resembling other unspecific lung diseases and thus it may cause differential-diagnostic dilemmas and delayed detection.
