Stinging insect identification in children with Hymenoptera venom allergy and their parents.

Introduction: The treatment of Hymenoptera venom allergy (HVA) is based among others on the proper identification of the culprit insect. Aim: To assess the accuracy in identifying stinging insects by children with HVA and their parents. Material and methods: Participants were recruited from a paediatric medical centre. The data on their demographics, sting history and ability of insect identification (based on pictures) were obtained using a questionnaire. The study sample consisted of 102 children with HVA and their parents as well as 98 children without HVA and their parents. Results: The rates of subjects correctly identifying insects in the groups were 91.2%, 92.5%, 78.8%, 82.4%, respectively. When compared to children with HVA, those without HVA were less likely to correctly identify the bee, bumblebee and hoverfly. In this group, the correct identification of the wasp was more common among children living in the countryside. The correct identification of the bee and bumblebee by children without HVA was more common among children living in the city. Conclusions: Some children with HVA and their parents cannot correctly identify stinging insects despite previous life-threatening allergic reactions. The ability to identify stinging insects may depend on the HVA diagnosis and place of residence.

Pain measurement in the older people: evaluation of the psychometric properties of the Geriatric Pain Measure (GPM-24) - polish version.

BACKGROUND: Chronic pain in older people is of particular importance not only with regard to negative subjective experience but also as an indicator of the quality of medical care. Brief scales to assess pain may help health professionals with early recognition and treatment to avoid patient suffering. However, these scales should be adapted to the cultural context to provide valid assessments. The aim of this study was to evaluate the psychometric properties of the Polish translation of the Geriatric Pain Measure - 24 (GPM-24) in older people. METHODS: The study was conducted among 181 people aged 65 and over with chronic (noncancer) pain of varying intensity lasting more than 6 months. Construct validity was assessed using the principal component analysis (PCA) method with oblimin rotation. Criterion validity was evaluated by correlating the scores of the GPM-24 with the scores of the McGill-Melzack questionnaire (MPQ). The reliability of the GPM-24 was estimated in terms of internal consistency using Cronbach's alpha coefficients. RESULTS: The PCA revealed a 6- component structure of the set of items that constituted the GPM-24. Most of these components were defined by items included in the same subscale, similar to the result obtained by the original scale's authors. There were significant correlations between the GPM-24 and some dimensions of MPQ: affective (rho = 0.25, p = 0.001), present pain intensity (rho = 0.44, p < 0.001), pain rating index total (rho = 0.31, p < 0.001), and number of words chosen (rho = 0.26, p < 0.001). The value of the standardized Cronbach's alpha equalled 0.89 and thus confirmed the high reliability of the GPM-24. CONCLUSIONS: The Geriatric Pain Measure - 24 is a reliable and valid tool that is recommended for the monitoring and multidimensional assessment of chronic pain in older people in daily practice as well as in clinical trials. TRIAL REGISTRATION: Statutory research "Chronic pain in people over 65 years of age" K/ZDS/005733, conducted in 2015-2018.

Current practices in diagnosis of Hymenoptera venom allergy in Poland.

Introduction: Hymenoptera venom allergy (HVA) is associated with a high risk of anaphylaxis. Effective treatment of HVA patients requires allergologists' familiarity with the latest HVA recommendations. Aim: Evaluation of current practices in HVA diagnosis in Poland. Material and methods: A survey questionnaire was conducted in 32 HVA centres in Poland. Results: The response rate was 97%. There were 1829 patients evaluated due to HVA in 2015. Sixty six percent (n = 21) of the centres used skin prick tests, out which 90% (n = 19) used 100 µg/ml of the venom extract as the highest concentration. All the centres performed intradermal tests (IDT) and serum specific IgE (sIgE), an initial diagnostic tool in 91% (n = 29). The highest venom concentration in IDT was 1 µg/ml in 75% (n = 24), 0.1 µg/ml in 16% (n = 5), 0.01 µg/ml in 3% (n = 1) and 10 µg/ml in 6% (n = 2). Baseline serum tryptase was assessed in 84% of the centres (n = 27), out of which 53% (n = 17) tested all their patients, whereas 31% (n = 10) checked only those with life-threatening reactions. In case of negative IDT/sIgE, 59% of the centres (n = 19) performed components evaluation, while 19% (n = 6) did the basophil activation test. In case of no identification of the culprit insect and sensitization to both venoms, VIT employed venom with higher sIgE. Conclusions: Most allergology centres in Poland follow HVA guidelines. We identified two inaccuracies in their HVA management including non-adequate venom concentration in IDT and a false belief in correspondence between sIgE concentration and severity of allergic reactions.

Is the clinical manifestation of anaphylaxis in children influenced by the trigger of reaction?

INTRODUCTION: The number of anaphylaxis diagnoses in children is rising, being still based on the clinical picture. AIM: To determine whether triggers of anaphylaxis influence its clinical characteristics in children and adolescents. MATERIAL AND METHODS: The study group included 114 children (5 months-17 years, mean age: 8.0 ±4.8 years), (66%: boys) with the episode of anaphylaxis up to 1 year back. Medical data were entered to the NORA Registry by means of a validated structured on-line questionnaire. RESULTS: Three most frequent triggers of anaphylaxis were: insect venom (47.4%), food (35.1%), drugs (5.3%), with a predominance of food (egg white, cow's milk, nuts and peanuts) in the 0-6 years age group, while insect venom (bee predominance) in the 7-17 years age group (p = 0.016). Clinical manifestations differed between food vs. venom allergic reactions and presented as gastro-intestinal (GI) (61.4%) (p = 0.004), respiratory (RS) (93.9%) (p = 0.036), and cardiovascular (CVS) (74.6%) (p = 0.022) symptoms. Among objective symptoms, vomiting was the most common symptom in the 0-2 years age group (47.1%) (p = 0.006), while hypotension in those aged 7-12 years (40%) (p = 0.010). Severity of symptoms evaluated as Mueller's grade (IV - 74.5%) and as Ring and Messmer's grade (III - 65.8%), depended on the trigger (p = 0.028, p = 0.029, respectively). Life-threatening symptoms occurred in 26 children (fall of the blood pressure - 22%, loss of consciousness - 4.4%). CONCLUSIONS: The clinical manifestation of anaphylaxis in children is both trigger and age dependent, irrespective of the gender. A typical patient with food anaphylaxis was younger, presenting predominantly GI symptoms, while a typical patient with venom anaphylaxis was older, with mostly cardiovascular symptoms.

Intervention in anaphylaxis: the experience of one paediatric centre based on NORA reports.

Introduction: Intramuscular adrenaline administration is the primary intervention in anaphylaxis. Aim: To analyse the data on intervention in children admitted due to anaphylaxis to the tertiary paediatric centre and compare them to the data from the Network for Online-Registration of Anaphylaxis. Material and methods: A validated structured on-line questionnaire was used to collect data concerning the first and second-line intervention in anaphylaxis. The study was conducted in cooperation with the European Anaphylaxis Registry. Results: The study group comprised 114 children (76 boys, 66.87%) aged 5 months-17 years with the predominance of moderate-to-severe anaphylaxis (grade III in Ring and Messmer's, and grade IV in Mueller's scale). In 103 (90.4%) children the first line of medical intervention was provided by medical staff. In the first-line intervention 39 (34.8%) children were given adrenaline. Five (4.4%) children were given the second dose of adrenaline and were admitted to the intensive care unit. In the second-line intervention adrenaline was given to 12 (15.6%) children. In one third it was at least the second reaction to the same trigger. Children treated with adrenaline were older (9.3 ±4.8 years), in comparison to those not treated (7.3 ±4.6 years, p = 0.034). Directly after the episode of anaphylaxis the children got the prescription for the adrenaline autoinjector in 35.1%, emergency training in 7.9%, and counselling on the avoidance of the anaphylaxis trigger in 30.7%. Grade III R&M reaction increased 3-fold the odds of AAI prescription (95% CI: 1.08-8.15). Conclusions: There is a strong need to continue education on proper management of anaphylaxis in children.

Venom allergy treatment practices in Poland in comparison to guidelines: next edition of the national audit.

INTRODUCTION: Venom immunotherapy treatment (VIT) is the only causal treatment of hymenoptera venom anaphylaxis, which aims to provide long-lasting immunoprotection against severe reactions to subsequent stings. AIM: To reassess the compliance of VIT procedures in the Polish allergy centres with the European guidelines. MATERIAL AND METHODS: A structured questionnaire survey conducted in all 33 VIT-centres. The response rate was 94%. RESULTS: The ultrarush initial protocol was the most common protocol (71%, n = 22), usually lasting for 3.5 h (50%, n = 7). The most frequent (36%, n = 11) time interval from the initial to the first maintenance dose (MD) was 14 days, ranging from 7 to 35 days. All centres used an MD of 100 µg. The most frequent time interval between subsequent MDs was 4 weeks (58%, n = 18). Five years' of VIT was declared by 71% (n = 22). Before the termination of treatment, more than half of the centres (58%, n = 18) performed sIgE and almost half (42%, n = 13) performed skin tests. To confirm VIT efficacy, few centres (26%, n = 8) conducted the sting challenge. About half of centres provided the patients with an adrenalin auto-injector both at the time of initial diagnostics and at the end of treatment. More than half (55%, n = 17) used antihistamines in all patients. Almost half (45%, n = 14) declared to stop treatment with ß-blockers and almost one fourth (23%, n = 7) discontinued angiotensin-converting-enzyme inhibitors. CONCLUSIONS: In the most important procedures, there is a very high compliance with the guidelines. In the areas where the guidelines are not precise, we observed a large spread of results.

Simplification of intradermal skin testing in Hymenoptera venom allergic children.

BACKGROUND: The direct comparison between children and adults with Hymenoptera venom anaphylaxis (HVA) has never been extensively reported. Severe HVA with IgE-documented mechanism is the recommendation for venom immunotherapy, regardless of age. OBJECTIVE: To determine the differences in the basic diagnostic profile between children and adults with severe HVA and its practical implications. METHODS: We reviewed the medical records of 91 children and 121 adults. RESULTS: Bee venom allergy was exposure dependent, regardless of age (P < .001). Atopy was more common in children (P = .01), whereas cardiovascular comorbidities were present almost exclusively in adults (P = .001). In the bee venom allergic group, specific IgE levels were significantly higher in children (29.5 kUA/L; interquartile range, 11.30-66.30 kUA/L) compared with adults (5.10 kUA/L; interquartile range, 2.03-8.30 kUA/L) (P < .001). Specific IgE levels for culprit insect venom were higher in bee venom allergic children compared with the wasp venom allergic children (P < .001). In adults, intradermal tests revealed higher sensitivity, accompanied by larger area of skin reactions, regardless of type of venom. At concentrations lower than 0.1 µg/mL, 16% of wasp venom allergic children and 39% of bee venom allergic children had positive intradermal test results. The median tryptase level was significantly higher in adults than in children for the entire study group (P = .002), as well as in bee (P = .002) and wasp venom allergic groups (P = .049). CONCLUSION: The basic diagnostic profile in severe HVA reactors is age dependent. Lower skin test reactivity to culprit venom in children may have practical application in starting the intradermal test procedure with higher venom concentrations.

Natural history of Hymenoptera venom allergy in children not treated with immunotherapy.

BACKGROUND: Differences in treatment approach still exist for children after systemic sting reactions. In addition, there are still some doubts about when systemic reactors should be treated with venom immunotherapy (VIT). OBJECTIVE: To determine the rate of sting recurrence and natural history of Hymenoptera venom allergy (HVA) in children not treated with VIT. METHODS: A total of 219 children diagnosed as having HVA who were not treated with VIT were identified in 3 pediatric allergology centers. Survey by telephone or mail with the use of a standardized questionnaire was conducted. The number of field re-stings, subsequent symptoms, and provided treatment were analyzed. RESULTS: A total of 130 of the 219 patients responded to the survey, for a response rate of 59.4%. During the median follow-up period of 72 months (interquartile range, 52-85 months), 44 children (77% boys) were stung 62 times. Normal reactions were most common, occurring in 27 patients (62%). Severe systemic reactions (SSRs) occurred in 8 (18%) of those who were re-stung. The subsequent reaction was significantly milder (P < 0.001), especially in the case of patients re-stung by the same insect (P < .001). None of the children with prediagnostic large local reactions and negative test results for venom specific IgE developed SSRs after re-sting by the culprit insect (P = .03). In children with SSRs, median time from diagnosis to re-sting was 2 times longer than that in those with large local reactions and normal reactions (P = .007). CONCLUSIONS: Most children with HVA not treated with VIT reported milder reactions after a re-sting. Probability of SSR to re-sting increases along with the severity of initial reaction.

How Factor Analysis Results May Change Due to Country Context.

PURPOSE: To present how factor analysis results of a Practice Environment Scale of the Nursing Work Index (PES-NWI) translation changed due to country context. DESIGN: Validity and reliability analysis of a cross-culturally adapted, Polish translation of the PES-NWI came from a cross-sectional, national survey that included 2,605 registered nurses working in surgical (50.4%) and medical (49.6%) units of 30 Polish hospitals. METHODS: Exploratory factor analysis (EFA) using the principal component analysis (PCA) method with varimax rotation and confirmatory factor analysis (CFA) was used to examine factor structure of the instrument in the Polish context. Zero-order and partial Pearson correlation coefficients were used to establish the range of variance shared by the dimensions of the Polish version. The Cronbach's alpha coefficient determined internal consistency reliability. The internal consistency of the scale was also tested based on Kline's criterion. FINDINGS: The PCA conducted in the sample of Polish nurses extracted six factors, explaining together 56% of the total variance. The varimax rotation, however, restricted results to five factors, explaining 52.7% of the total variance and generating a factor structure closer to that based on previous studies. The CFA model, based on a PCA solution with five nonorthogonal factors, fitted data better than the theoretically driven model. CONCLUSIONS: Dimensions of the PES-NWI nurses' work environments remain conceptually consistent in Poland, but load differently. Health system or nursing profession factors related to the country context are potential explanations for these differences. CLINICAL RELEVANCE: When using a translation of the Practice Environment Scale of the Nursing Work Index-Revised to examine the influences of work environment quality on nursing and patient outcomes, it is important to consider contextual differences when using results to inform policy.

Factors affecting Polish nurses' willingness to recommend the hospital as a place of care.

BACKGROUND: Nurses constitute the major professional group offering constant hospital patients' care. Willingness to recommend their hospital reflects confidence in the offered care, satisfaction and identification with the work place. The aim of the present study has been to investigate which elements of hospital environment and nurse personal related factors predict recommendation of the hospital as a place of care by employed nurses. MATERIAL AND METHODS: Cross-sectional, correlation study was, based on 1723 self-reported, anonymous questionnaires of nurses working in 30 acute hospitals. Data was analyzed using the logistic regression model, with general estimation equations. RESULTS: About 25% of nurses were unwilling to recommend their hospital as the place of care. The odds ratio (OR) of the lack of willingness to recommend the hospital was related to assessment of patients' safety (OR = 0.28, 95% confidence interval (CI): 0.18-0.46, p = 0.00), decrease in the quality of patient care during the preceding year (OR = 0.62, 95% CI: 0.41-0.93, p = 0.02), overall work conditions (OR = 0.35, 95% CI: 0.22-0.57, p = 0.00), weak cooperation between nurses and physicians (OR = 0.37, 95% CI: 0.25-0.54, p = 0.00), poor work schedule flexibility (OR = 0.74, 95% CI: 0.55- 0.99, p = 0.04) and educational opportunities (OR = 0.71, 95% CI: 0.54-0.95, p = 0.02) and the level of nurses depersonalization (OR = 1.78, 95% CI: 1.18-1.68, p = 0.00). CONCLUSIONS: The hospital manager should consider strategies which improve patients' safety and the staff working conditions. Thanks to that they will also achieve better and more competitive image of the hospital in the local community. Med Pr 2016;67(4):447-454.

Development of Parents' of Children with Hymenoptera Venom Allergy Quality of Life Scale (PoCHVAQoLS).

INTRODUCTION: Venom allergy in children, as a potentially life-threatening disease, may have a considerable impact on the quality of life of the parents of the affected patients. AIM: To present development of the quality of life scale for such parents. MATERIAL AND METHODS: The study sample included 70 parents of children with a history of insect sting reaction, referred for consultations to the allergy centre of the University Children's Hospital of Krakow, Krakow, Poland, in 2000-2010. An initial pool of 56 items divided into 6 domains was prepared. The items with intercorrelations higher than 0.7 were removed from each domain and principal component analysis was conducted for each domain separately to provide a one-dimensional subscale for each domain. Reliability of the subscales was assessed using the Cronbach α coefficient in terms of the Classical Test Theory and with the rho coefficient in terms of the Item Response Theory. The multidimensionality of the scale was tested using multitrait scaling. RESULTS: Two to four items from each domain were selected to constitute five subscales. Both the rho and α coefficients for all the subscales were 0.75 or higher. The multitrait method showed that almost all the items indicated stronger correlations with their own subscale than with other subscales. Correlations between subscales were lower than 0.5. CONCLUSIONS: The presented scale consists of high validity and reliability subscales measuring the quality of life of parents of Hymenoptera venom allergic children. As their quality of life is strongly related to the health of their children, such information may be helpful in everyday clinical practice.

Analysis of the feelings of patients with HIV/AIDS and HCV in contact with health professionals. Assessment based on cases of stigmatisation and discrimination. / Analiza odczuc pacjentów z HIV/AIDS i HCV w kontakcie z przedstawicielami zawodów medycznych. Ocena w oparciu o przypadki stygmatyzacji i dyskryminacji.

OBJECTIVES: This study aimed to investigate incidences of stigmatisation and discrimination by selected health professionals against patients with HIV/AIDS and HCV, and to assess how these affected feelings in both groups. METHODS: The study involved 160 patients - 80 diagnosed with HIV/AIDS in the baseline group and 80 with HCV in the comparison group. Patients were recruited from among patients treated in two outpatient clinics of the University Hospital in Krakow. RESULTS: Incidents of stigmatisation and discrimination were observed significantly more often in the HIV/AIDS group compared to the HCV group. According to the patients, incidents of stigmatisation and discrimination on the part of medical staff occur due to fear and a sense of threat from infection with the viruses. The experience of stigmatisation and discrimination by patients manifests itself in the impediment or denial of healthcare services by medical professionals. Some of the medical staff blamed the patients for the infection, expressed disrespect and verbal aggression towards them, and treated them worse when they found out about the infection. Their emotional state depended on the nature of the relationship with the medical staff triggered by stigmatisation and discrimination. CONCLUSIONS: Stigmatisation and discrimination by medical staff against patients were, according to the respondents, linked to fear of infection but confirmation of this relationship would require further research. In the course of these cases, patients experienced pejorative verbal evaluation, impediment or denial of health services, which could have specific health consequences. These types of attitudes had a negative impact on their emotional state.

Skin prick tests are not useful for the qualification for venom immunotherapy in children.

Background: The basis for qualification for venom immunotherapy (VIT) is the fulfilment of both the clinical and immunological criteria. Diagnostic tests that confirm the immunological criterion of an IgE-mediated sensitization include skin prick tests (SPT), intradermal tests (IDT), and serum specific IgE (sIgE) for the culprit venom. Objective: This study aimed to assess the usefulness of SPT as the immunological marker in the diagnosis of insect venom sensitization in children with history of systemic reaction (SR) to insect sting evaluated by means of I-IV-grades Mueller's scale. There are no such studies in children. Methods: This cross-sectional study sample consisted of 416 children aged 3-18 years (mean age 10.6 ± 3.8), 76% males, all with the history of a systemic reaction (SR) after a Hymenoptera sting (48% of grade III/IV according to Mueller scale), diagnosed between 1999 and 2019 in the tertiary referral centre. The standard diagnostic tests were used. Specificity, sensitivity, and positive and negative predictive values were computed to assess the diagnostic properties of the clinical tests to distinguish between mild and severe SR. To assess the relative value of an individual test in predicting the qualification to VIT we incorporated the Shapley value (SV). Results: Positive SPT results were found in up to no more than 3% of children; among them less than 1% had only positive SPT and were negative for sIgE and IDT. Approximately 85% of the children had detectable venom sIgE, followed by positive IDT (75%). Almost 70% of children had positive both sIgE and IDT results. In children with grade III/IV reaction, about 80% of children had positive results of both of these tests. sIgE and IDT had sensitivity >0.80, whereas SPT had high specificity (>0.97) in differentiating between mild and severe SR. Relative value of diagnostic tests in predicting qualification to VIT varied between venoms. Bee venom IDT had higher SV (0.052) than sIgE (0.041). In contrast, wasp venom sIgE had higher SV (0.075) than IDT (0.035). Conclusion: SPTs are not an useful immunological marker of venom sensitization in children, and eliminating SPT does not result in a loss of diagnostic accuracy. Limiting diagnostics to venom sIgE and IDT would shorten the procedure and reduce costs. Future studies are needed to determine if venom sIgE as the first line diagnostic test, with IDT added only if the venom sIgE is undetectable, is an optimal diagnostic process.

[Methodological aspects of use of scales as measurement instruments in epidemiological studies]. / Aspekty metodologiczne uzycia skal jako instrumentów pomiarowych w badaniach epidemiologicznych.

Quality of life and health status measurement in epidemiological studies requires high level approach. It concerns not only the matter of choice or development of measurement tools; it requires also consciousness of the consequences, which may follow mistakes made during their development. Development of new measurement tool by means of adaptation of tool used in another country also may be touched by the risk of committing some mistakes, which may be followed by serious consequences including problems with interpretation of obtained data. This paper presents examples of mistakes made during development of questionnaires and some guidelines, which let to avoid the most serious mistakes.

Cultural adaptation of the Safety Attitudes Questionnaire - Short Form (SAQ-SF) in Poland.

BACKGROUND: It is essential to provide safe healthcare in complex, difficult, and quickly changing conditions. The quality of healthcare services directly influences the safety of both the patients and staff. Understanding healthcare staff attitudes toward safety in the healthcare delivery context is foundational for building a culture of safety. AIM OF THE WORK: To adapt, via a structured translation methodology, the Safety Attitudes Questionnaire-Short Form (SAQ-SF), which assesses how employees of the health care sector perceive the safety climate in their workplace, to the Polish context. METHODS: Using a content validation approach to structure the translation process, we tested and psychometrically analysed the translated SAQ-SF. The sample comprised 322 employees of a district hospital (second referral level, which ensures 24/7 emergency care services) in Poland. RESULTS: The reliability of the sub-scales of the Polish version of the SAQ-SF ranged from 0.66 to 0.95. The discriminatory power of particular SAQ items ranged between 0.02 and 0.90. For 6 out of the 8 scale dimensions, the questions with the highest factor loadings were those measuring the same dimensions of the safety climate, according to the original scale. CONCLUSIONS: The Polish version of the SAQ-SF (SAQ-SF-PL) meets the criteria of psychometric and functional validation as well as demonstrates good reliability as a measure of patient safety culture in the Polish context. The SAQ-SF-PL is an instrument that enable a valid and reliable assessment of patient safety climate in the Polish healthcare facilities and identify opportunities for improvement. International comparisons will also become easier.

Health promotion for older people in the Czech Republic in a European perspective.

This article describes health promotion for older people in the Czech Republic from the European perspective. It is based on findings from the European project healthPROelderly. Implementation of health promotion in the Czech republic as a new public health concept is outlined from the historical point of view. Structures and processes of health promotion in the Czech Republic are described in the context of social policy, demography and health. The European project healthPROelderly is presented and the outcomes of an international literature search statistically analysed. Participating countries were divided into three macro-regions according to their geographical location and political and historical tradition - Mediterranean, West-European and formerly East-European macro-regions. The outcome of correspondence analysis partially confirms the hypothesis on the cultural background of the health promotion activities and strategies. Concerning themes addressed by health promotion projects most countries belonging to the Mediterranean or "Western European" macro-regions have concentrated on similar themes whereas this is not valid for the countries of the "Former Eastern European" macro-region. The hypothesis on macro-regional similarities in relation to settings of health promotion projects was not confirmed. In the conclusions the location of the Czech Republic in an international perspective is discussed and three Czech selected best practice projects are evaluated in relation to the statistical findings.

[Students knowledge on carbon monoxide toxicity]. / Poziom wiedzy studentów na temat toksycznosci tlenku wegla.

The results of questionnaire research on carbon monoxide (CO) poisoning in students of State Higher Vocational School in Nowy Sacz (Institutes of Economy, Pedagogic, Technical and Health) are presented in the study. The mean age of the group examined, with a female predomination (77.6%) was 22.7 +/- 4.94 years. The questionnaire covered demographic data and knowledge on CO source, exposure, most frequent and most severe symptoms, most severe sequels, risky behavior and risk groups in CO poisoning. The results obtained indicate on inadequate knowledge on CO poisoning even in young students population. The proper education and prophylaxis activity is necessary to avoid accidental CO poisoning, especially that they also occur in spring-summer season.

[Diagnosis and venom specific immunotherapy (VIT) in allergic children in Poland--how much the current practice follows the international guidelines?]. / Diagnostyka i immunoterapia u dzieci z alergia na jad owadów blonkoskrzydlych (VIT) w Polsce--jak wyglda w praktyce zgodnosc z miedzynarodowymi wytycznymi?

INTRODUCTION: Insect venom allergy requires a high level approach adequate to allergy intensity. In case of severe IgE-mediated sting reactions, in children older than five years, venom immunotherapy is a treatment of choice. AIM: Identification of current practices applied to venom allergic children in Poland and their adherence to the international guidelines. METHOD: Questionnaire survey concerning diagnostic and treatment rules was carried out in 8 centres of pediatric allergology, based on a similar audit conducted in the United Kingdom [Diwakar L. et al. Clin Exp Allergy 2008, 38: 1651]. RESULTS: In 5 centres both RAST and SPT tests were used as the first line of investigation. Subsequently 6 centres performed IDT. In three centres baseline serum tryptase levels were estimated. In case of sensitization to both bee and wasp venom in a child with the history of severe systemic reaction, but uncertain culprit insect, specific venom immunotherapy with both venoms was practised by 2 centres. In systemic reaction and not-detectable IgE in 6 centres child was followed-up in 6-12 months. Antihistamine premedication concerned all children in 7 centres. Six-week interval between booster doses was applied in half of centres. A target dose equal 100 mcg was used in 7 centres. Similarly all centres practiced 3-5 five year period of VIT. CONCLUSIONS: In Poland current practice with venom allergic children was conducted in congruence with most of the recommendations.

[Adaptation of Vespide Allergy Quality of Life Questionnaire for Polish children with venom allergy and for their parents]. / Adaptacja kwestionariuszy jakosci zycia dla dzieci z alergia na jad owadów oraz dla ich rodziców.

Aim of the study was to assess validity and reliability of adaptations of VQLQ for Polish children with Hymenoptera venom allergy and their parents. Sample under study consisted of 73 children aged up to 14 years, who were treated with specific venom immunotherapy (VIT) in 2008 in centres conducting this procedure in Poland, and their parents. Theoretical validity of the scales was assessed with exploratory factor analysis using principal component analysis method. Reliability of the scales was assessed in terms of internal consistency with Cronbach alpha coefficient. Results of analysis showed that both scales measure 4 dimension of quality of life and reliability of scales measuring particular dimensions is at least acceptable in case of scale for children, and high in case of scale for parents. Both adapted scales are valid and reliable tools measuring quality of life in children with Hymenoptera venom allergy and their parents' quality of life in the face of child's allergy.

[Health-related quality of life in children with Hymenoptera venom allergy treated with VIT and quality of life of their parents]. / Jakosc zycia warunkowana stanem zdrowia dzieci z alergia na jad owadów blonkoskrzydlych leczonych VIT oraz jakosc zycia ich rodziców.

UNLABELLED: Hymenoptera venom allergy, although rare in children, by its potential fatalities, leads to many psychosocial consequences, influencing quality of life of children and their parents. Aim of this paper is the estimation of health-related quality of life of venom allergic children treated with specific immunotherapy, and their parents. Assessment of factors influencing health-related quality of life levels was also performed. MATERIAL AND METHODS: Sample under study consisted of 73 children: mean age 10.6, SD 2, 4, treated because of Hymenoptera venom allergy in 5 clinical allergy centers in Poland. Data was collected using VQLQ questionnaire adapted for children and their parents. Determinants of quality of life were assessed with multivariate linear and logistic regression models. Analysis were done with SPSS 15 for Windows package. RESULTS: Girls reported higher level of anxiety than boys (B = 0.47; 95% CI = (0.01; 0.94)). Level of caution in children increased along with increase of their anxiety against re-sting (B = 0.49; 95% CI = (0.27; 0.71)). Level of anxiety of children who were under treatment from 6 months to 2 years was lower than level of anxiety of parents of children treated shorter than 6 months (B = -1.21; 95% CI = (-2.16; -0.25)). The lowest level of caution was reported by parents of children aged 10 year or less (B = -0.86; 95% CI = (-1.67; -0.05)), while the highest was reported by parents of children aged 11 years (B = 0.86; 95% CI = (0.20; 1.53)) in comparison to parents of children aged 12 years or more. Parents' caution increased along with increase of their anxiety (B = 0.61; 95% CI = (0.40; 0.83)). Higher level of limitations was imposed by parents of children treated with rush or ultra rush method, in comparison to parents of children treated with conventional method (B = 1.27; 95% CI = (0.21; 2.33)).
