RESUMEN

BACKGROUND: Pollen allergy poses a significant health and economic burden in Europe. Disease patterns are relatively homogeneous within Central and Northern European countries. However, no study broadly assessed the features of seasonal allergic rhinitis (SAR) across different Southern European countries with a standardized approach. OBJECTIVE: To describe sensitization profiles and clinical phenotypes of pollen allergic patients in nine Southern European cities with a uniform methodological approach. METHODS: Within the @IT.2020 multicenter observational study, pediatric and adult patients suffering from SAR were recruited in nine urban study centers located in seven countries. Clinical questionnaires, skin prick tests (SPT) and specific IgE (sIgE) tests with a customized multiplex assay (Euroimmun Labordiagnostika, Lübeck, Germany) were performed. RESULTS: Three hundred forty-eight children (mean age 13.1 years, SD: 2.4 years) and 467 adults (mean age 35.7 years SD: 10.0 years) with a predominantly moderate to severe, persistent phenotype of SAR were recruited. Grass pollen major allergenic molecules (Phl p 1 and/or Phl p 5) ranged among the top three sensitizers in all study centers. Sensitization profiles were very heterogeneous, considering that patients in Rome were highly poly-sensitized (sIgE to 3.8 major allergenic molecules per patient), while mono-sensitization was prominent and heterogeneous in other cities, such as Marseille (sIgE to Cup a 1: n = 55/80, 68.8%) and Messina (sIgE to Par j 2: n = 47/82, 57.3%). Co-sensitization to perennial allergens, as well as allergic comorbidities also broadly varied between study centers. CONCLUSIONS: In Southern European countries, pollen allergy is heterogeneous in terms of sensitization profiles and clinical manifestations. Despite the complexity, a unique molecular, multiplex, and customized in-vitro IgE test detected relevant sensitization in all study centers. Nevertheless, this geographical diversity in pollen allergic patients imposes localized clinical guidelines and study protocols for clinical trials of SAR in this climatically complex region.

RESUMEN

BACKGROUND: Food allergy can have a major impact on quality of life of children and their parents. Questionnaires have been developed to measure the impact of this disorder. We aimed to validate the EuroPrevall questionnaire on Food Allergy-Quality of Life Questionnaire, Parent Form (FAQLQ-PF) and the Food Allergy Independent Measure (FAIM), translated into Spanish. METHODS: The internal consistency of the FAQLQ-PF and the FAIM, translated into Spanish (Spain) and completed by the parents of 74 children with IgE-mediated food allergy, were evaluated with Cronbach's alpha. To test construct validity of the FAQLQ-PF, its correlation with the FAIM was also calculated. To assess their discriminant validity, we compared the values of both depending on the number of offending foods and for children with and without anaphylaxis. RESULTS: The values of Cronbach's alpha for the three domains in the FAQLQ-PF were over 0.9. The value of alpha for FAIM questions was below 0.6, which was attributed to the wording of one question. When this question was removed, alpha increased to over 0.70. There was a significant correlation between the FAQLQ-PF score and the FAIM. There were significantly poorer FAQLQ-PF scores in children with more food allergies and worse FAIM in those who had had anaphylaxis. CONCLUSIONS: The Spanish version of the FAQLQ-PF had a good internal consistency, good construct validity and validity to discriminate patients with more food allergies and anaphylaxis. It can be used as a tool to evaluate and monitor the quality of life in families with food allergic children.

RESUMEN

SUMMARY Two clusters of confirmed cryptosporidiosis infections were detected in Navarra, Spain, in the summer of 2012, in the context of an increased incidence in the region. Molecular subtyping of Cryptosporidium hominis determined that one cluster, occurring in an urban area, was due to the predominant circulating subtype IbA10G2R2 and the other cluster, with cases occurring in a rural area, was due to a rare subtype IaA18R3. No single exposure was associated with infection, although exposure to certain children's pools was reported by a majority of patients interviewed in each cluster. Genotyping tools were useful in the investigation and could aid investigation of cryptosporidiosis outbreaks in Spain in the future.

RESUMEN

The European Academy of Allergy and Clinical Immunology (EAACI) Food Allergy and Anaphylaxis Guidelines, managing patients with food allergy (FA) in the community, intend to provide guidance to reduce the risk of accidental allergic reactions to foods in the community. This document is intended to meet the needs of early-childhood and school settings as well as providers of non-prepackaged food (e.g., restaurants, bakeries, takeaway, deli counters, and fast-food outlets) and targets the audience of individuals with FA, their families, patient organizations, the general public, policymakers, and allergists. Food allergy is the most common trigger of anaphylaxis in the community. Providing children and caregivers with comprehensive information on food allergen avoidance and prompt recognition and management of allergic reactions are of the utmost importance. Provision of adrenaline auto-injector devices and education on how and when to use these are essential components of a comprehensive management plan. Managing patients at risk of anaphylaxis raises many challenges, which are specific to the community. This includes the need to interact with third parties providing food (e.g., school teachers and restaurant staff) to avoid accidental exposure and to help individuals with FA to make safe and appropriate food choices. Education of individuals at risk and their families, their peers, school nurses and teachers as well as restaurant and other food retail staff can reduce the risk of severe/fatal reactions. Increased awareness among policymakers may improve decision-making on legislation at local and national level.

RESUMEN

BACKGROUND: We hypothesized that minimally invasive surgery was superior to conventional surgery for total hip arthroplasty procedure. PURPOSE: To compare the results of total hip replacement (THR) made by minimally invasive lateral approach with the results of THR made by conventional lateral approach. MATERIALS AND METHODS: Prospective, randomized trial. Fifty patients were selected and then divided into two groups based on utilized approach. DATA COLLECTED: Perioperative bleeding, postoperative pain, time of recovery, components orientation, complications and functional results. Five-year follow-up. RESULTS: No differences were found in blood loss, postoperative pain, surgical time, components orientation, rate of complications or functional result. Minimally invasive lateral approach produced faster recovery with less hospital stay and earlier walking start. CONCLUSION: Our results suggested that minimally invasive lateral approach has not provided significant benefits over conventional lateral approach for the implantation of a total hip arthroplasty.

RESUMEN

BACKGROUND: We have observed that some cases of food anaphylaxis were followed by severe thrombosis associated to anticardiolipin antibodies. Food anaphylaxis associated with antiphospholipid syndrome has seldom been published. OBJECTIVE: The aims were: 1) to test anticardiolipin antibodies in an important number of patients with anaphylaxis due to vegetal foods and their relationship with possible thrombosis; and 2) to study seed and fruit hypersensitivity in patients with previous thrombotic events associated with antiphospholipid antibodies (aCL). METHODS: We included 30 patients diagnosed of thrombosis associated with aCL, 52 patients who suffered from anaphylaxis due to seeds or fruits, and 120 control patients. Haematological, cardiopulmonary vascular and rheumatologic studies had been performed as needed. In vivo and in vitro allergy tests with a large battery of vegetal allergens were carried out in all the patients. Measurement of IgG aCL antibodies and specific IgE to vegetal food was done by ELISA and CAP-FEIA (Phadia). Immunodetection and inhibitions with lipoproteins belonging to seeds were performed. RESULTS: Seventy-five percent of the patients diagnosed as having antiphospholipid primary syndrome had specific IgE against different proteins from different vegetable allergens, most of them seeds, and clearly against lipoproteins that were also recognised by the patients with food anaphylaxis but not by the control cases. Among the patients with anaphylaxis, 28% had anticardiolipin antibodies and 17.3% thrombosis. CONCLUSION: Our study suggests that seed lipoproteins which cause severe food anaphylaxis might have a potential role in the antiphospholipid syndrome and related thrombosis.

RESUMEN

Allergy affects at least one-quarter of European schoolchildren, it reduces quality of life and may impair school performance; there is a risk of severe reactions and, in rare cases, death. Allergy is a multi-system disorder, and children often have several co-existing diseases, i.e. allergic rhinitis, asthma, eczema and food allergy. Severe food allergy reactions may occur for the first time at school, and overall 20% of food allergy reactions occur in schools. Up to two-thirds of schools have at least one child at risk of anaphylaxis but many are poorly prepared. A cooperative partnership between doctors, community and school nurses, school staff, parents and the child is necessary to ensure allergic children are protected. Schools and doctors should adopt a comprehensive approach to allergy training, ensuring that all staff can prevent, recognize and initiate treatment of allergic reactions.

RESUMEN

AIM: Our objective was to compare the results of PCCP (Percutaneous Compression Plate) device and Gamma 3 nail for the treatment of stable trochanteric hip fractures and to demonstrate that PCCP device is a minimally invasive system. METHOD: Prospective, randomized trial. Eighty patients aged 60 and over with stable trochanteric fracture were selected and then randomized using a table of randomized numbers. Length of time of operative procedure, hemoglobin levels at 6 and 48 h after surgery, packed cells units administered, and hospital stay were recorded. In addition, the postoperative complications in the first year after the surgery was collected. RESULTS: No differences were found in hospital stay, surgical time, blood loss, functional outcome at 1-year follow-up, neck-shaft angle, fracture collapse, and mortality. CONCLUSIONS: PCCP and Gamma 3 have not presented significant differences in any measured parameter for treatment of stable trochanteric fractures. Therefore, the PCCP system is shown to be as minimally invasive as the Gamma 3.

RESUMEN

The diffusion of the outlines of antibiotic sensitivity is a practice that is recommended for improving the prescription of antibiotics and for controlling the appearance and spread of resistances. During the years 2003 and 2004, data was gathered on the sensitivity to antibiotics of the main bacteria isolated in outpatient urine cultures, coprocultures, faringoamygdal and otic smears in the Pamplona health area, which attends to a population of approximately 400,000 inhabitants. Of the 9,495 uropathogens isolated, 90% were sensitive to amoxicillin-clavulanate, 96.4% to 2nd generation cephalosporins, 95.3% to phosphomycin and 97.7% to nitrofurantoin. One point eight percent (1.8%) of the strains of Escherichia coli isolated in urine were producers of extended spectrum b-lactamases, while 0.5% of the urinary isolations of Klebsiella pneumoniae were producers of this type of b-lactamases. Ninety-six point five percent of the 797 isolations of Salmonella serotipo Enteritidis were sensitive to cotrimoxazol, and 97.5% of the 1,057 isolations of Campylobacter jejuni were sensitive to eritromycine. Of the 319 bacteria isolated in otitis media, 96.5% were sensitive to amoxyline. The Gram negative bacillae producers of otitis externa showed a sensitivity above 90% to ciprofloxacin, gentamycin and polimixin B. Twenty-nine point seven percent of the isolations of Streptococcus pyogenes were resistant to eritromycine. Fourteen point three percent and 17.4% of the Staphylococcus aureus isolated in the years 2003 and 2004 respectively were resistant to methicillin. Knowledge of the map of antibiotic sensitivity of the microorganisms in circulation in each geographical area is information that is necessary for the empirical choice of antibiotic treatment.

RESUMEN

OBJECTIVE: Long term clinical and radiological evaluation of results, survival, and peri- operative and post-operative complications of the patients who have been operated on for revision total hip arthroplasty using the impaction allografting and cemented rod technique. MATERIAL AND METHODS: An observational, analytical, prospective and non-random study was conducted on 26 patients who underwent revision total hip arthroplasty in our Hospital (1997-98). They were clinically and radiologically assessed, and a survival analysis of the implant was performed. RESULTS: Statistically significant differences were identified in the pre- and post-operative values, according to Harris and Merle D́Aubigne scores. The femoral components survival was considered as an endpoint of the revision replacement, which was 84% at a mean of 13 years. There were 9 intraoperative complications (6 were fractures) and they significantly affected the length of hospital stay. No post-operative complications were observed in 70% of the patients. None of the analysed variables had any influence on the radiological subsidence of the femoral component. DISCUSSION: Several techniques aim to solve the bone stock deficiency in revision total hip arthroplasty, but only impaction grafting attempts to recover it. CONCLUSIONS: The Ling's technique shows an improvement over the Merle D́Aubigne and Harris scores, in the medium-long term. The intraoperative complications are mainly an increase in the length of hospital stay and the number of days needed to be able to sit down. Ling's technique is a good option to consider in young patients where it is foreseeable that there is a new revision surgery in the future.

RESUMEN

A short-term (24 h) method of gill filament culture system was developed to predict the effects of environmental contamination and stress in fish. Gill culture system containing two or three rainbow trout gill filaments in sterile glutamine supplemented Leibovitz 15 (L-15) media was submitted for 24 h to six different treatments: (i) CONT (control, medium only); (ii) CORT (cortisol, 0.28 microM cortisol); (iii) BLOCK (glucocorticoid receptor blocker, 14 microM RU 486); (iv) CORT+BLOCK (cortisol and blocker, 0.28 microM cortisol+14 microM RU 486); (v) CORT+CU (cortisol and copper, 100 microM CuSO4+0.28 microM cortisol); (vi) CU (copper, 100 microM CuSO4). After 24 h, the overall gill structure and cellular components resembled those of salmonids in vivo. Lactate dehydrogenase (LDH) activity in the culture media increased in the CORT+CU and CU groups but was significantly lower in the CORT+CU compared to CU group. Apoptotic cells increased in the CORT and CORT+BLOCK. The numbers of glucocorticoid (GR) receptor-positive cells were lower in the CU group. This short-term culture system seems to be suitable for studying the effects of both external and internal stress effectors (toxicants and hormones respectively), as it contains all cell types found in the gills and the cells give similar biological response as in vivo.

RESUMEN

According to Weiss et al. [12], the main providers of asthma care in the United States in 1992 were general and family medicine + internal medicine (46%), pediatrics (19%), allergy (25%), pulmonary medicine (5%), and others (5%). In an overall climate of a shift of referral from primary care to the specialties, specialists will have to provide evidence that their intervention in the control of patients provides truly better clinical and economical outcomes than that of general practitioners. In order to support this hypothesis, we estimated: (1) the development of the costs of medication for asthma in a population of 40 million people (Spain) and (2) the correlation between these costs and the intervention of a specialized attendance. In Spain the annual costs incurring from allergic diseases are estimated to be approximately 1,500 million Euros and, the cost due to asthma alone is about 900-1,200 million Euros. There are two main ways to explain the size of these figures. First, the prevalence of allergic diseases is rising year by year. Second, the relevance of allergology in the control of asthma is often greatly reduced. This has resulted in a reduction in the etiological diagnosis and treatment with specific immunotherapy (SIT). However, SIT is the only specific causal treatment of allergic asthma that is able to modify the natural history of disease or disease progression. So, it is possible to hypothesize that this reduction in a proper etiological diagnosis and treatment could be a cause (among others) of increasing costs.

RESUMEN

We review the etiology of the dermatophytosis in Navarra (Spain) over a 5-year period and it is compared with previous studies. We have isolated 312 strains of dermatophyte fungi in 285 patients (188 men and 97 women). Trichophyton rubrum was the most frequently isolated species (58.6%) followed by Trichophyton mentagrophytes (26.2%) and Microsporum canis (10.5%). Concerning the location of the lesions, tinea pedis was the clinical pattern found in the greatest number of patients, followed by tinea corporis, tinea unguium and tinea capitis. Twenty eight percent of the isolations were accomplished in October and November. More than half of those patients questioned had had epidemiological contact with animals or practiced sports. The rise of tinea pedis in our region is emphasised. The possible causes of this increment are analyzed and some recommendations for its control are made.

RESUMEN

Latex allergy can be considered a problem of public health in at-risk populations. Although the figures on prevalence vary, approximately 1 % of the general population is sensitized to latex. To date, two determining factors for latex sensitization have been identified: an atopic predisposition and the number of operations. Among atopic patients or those at-risk for allergy, the prevalence of latex sensitization is between 3 and 20 times higher than that among the general population. Nevertheless, the effect of this factor seems to be modulatory and the determining factor seems to be the number of operations that children have undergone; the critical number is 5-6 interventions, after which the probability of sensitization increases considerably.All children who have undergone multiple operations should be considered as being at-risk. Children with spina bifida are especially at-risk. The reasons for this are still a matter of debate: the disease itself has been postulated as a specific risk factor, although other, possible associated factors could be determinant in triggering latex sensitization (the presence of a ventricular-peritoneal shunt, age at which surgery was performed, type of operation, etc.). Children with spina bifida and latex allergy show considerable differences in type of allergic sensitization; these differences seem to result from the different route of sensitization and could explain the variations observed in the clinical manifestations between children and adults: children become sensitized mainly by direct contact between latex particles and blood vessels and open mucosae while in adults the process takes place transcutaneously or by inhalation of aerosol particles. Consequently, the most frequent manifestation in children is urticaria while contact dermatitis and respiratory symptoms predominate in adults. Studies performed with immunoblotting have confirmed that children have IgE that almost constantly recognize low molecular weight latex proteins (14, 15 and 27 Kd) while this finding is less frequent in adults.The preventive measures in the pediatric population focus on avoidance of latex, especially in hospitals. Today, latex is ubiquitous, making complete avoidance difficult. When necessary, and whenever a latex-free environment cannot be guaranteed, presurgical medication can be used, although its utility is debatable. Although further studies are required, specific immunotherapy is one therapeutic possibility that may in future be used in children with latex allergy.

RESUMEN

This study evaluated the hydroxyapatite-coated femoral stem of the Bihapro hip prosthesis (Biomet Ltd, Bridgend, United Kingdom) using radiography, TC-99 scintigraphy, and bone densitometry. Thirty stems with >2 years of follow-up (mean: 31 months) were evaluated. No loosening or changes in the position of the implant were seen, and the mean subsidence was 2.2 mm. Radiography revealed a densification in the metaphyseal zone with reconstruction of the trabecular lines in 21 cases, while in 22 patients, radiolucent lines in the distal area of the femoral component were observed. Scintigraphy showed a diaphyseal normo-captation in 19 cases and a hypercaptation <1.4 with a mean index of 1.1 in 10 patients. Metaphyseal hypercaptation >1.4 was seen in 24 patients. Bone densitometry revealed increased density in the metaphyseal zones in 29 patients with a periprosthetic/normal bone quotient of 1.4.

RESUMEN

Hematological and physiological changes in the blood of juveniles of the freshwater fish, Prochilodus scrofa were determined after acute exposure to 20, 25, and 29 microgramsCu L-1 in water (pH 7.5; hardness 24.5 mg L-1 as CaCO3) for 96 h. Copper exposure to 25 and 29 microgramsCu L-1 caused significant increase in the hematocrit and red blood cell values. The increase in red blood cells was associated with increase in whole blood hemoglobin only in fish exposed to 29 microgramsCu L-1. Leukocytes increased following copper exposure and were significantly higher in fish exposed to 29 microgramsCu L-1. Differential leukocyte percentage displayed significant reduction in lymphocytes and an increase in neutrophils in fish exposed to 25 and 29 microgramsCu L-1. The percentage of monocytes remained unchanged after copper exposure. The thrombocytes did not change. There was a significant decrease in plasma [Na+] and [Cl-] and a significant drop in blood pH in fish exposed to 25 and 29 microgramsCu L-1 while [K+] showed significant increase in fish exposed to 29 microgramsCu L-1. Copper exposure led to ionoregulatory impairment, although chloride cell hypertrophy was induced. The changes in red blood cells suggest a compensatory response to respiratory surface reduction of gills (tissue damage and cell proliferation) in order to maintain oxygen transference from water to the tissues, allowing the fish to survive during the so-called shock phase of LC50 exposure, at least while at rest.

RESUMEN

BACKGROUND: Knowledge of the etiological agents of infections of the urinary tract and of the map of the antimicrobial sensitivity of each geographic zone is a practice recommended for improving the use of antibiotics and for facilitating the choice of empirical treatment. The aim of this study is to provide up-to-date information on the pathogen flora of outpatients urinary infections in our health area and their sensitivity to antimicrobials, based on the urinary cultivations carried out in the Microbiology laboratory of the Solchaga Outpatient Surgery during the last four years. MATERIAL AND METHODS: Between 1996 and 1999, we carried out 92,816 urinary cultivations of outpatients. The urine specimens were sown on plaques with chocolate agar and MacKonkey agar with calibrated loop. The antibiogram was carried out using the Kirby-Bauer method. RESULTS: The percentage of positive urinary cultivations was 17%. Gram-negative bacilli represented 88.9% of the isolations, Gram-positive cocci 11% and yeasts 0.1%. Escherichia coli was the most frequently isolated germ (71%). The sensitivity studies show that amoxycillin-clavulanic acid, first generation cephalosporins and fosfomycin maintain a sensitivity above 80%. CONCLUSIONS: Up-to-date knowledge of the most common pathogen flora and their sensitivity to antimicrobials makes it possible for a more suitable selection to be made of the antibiotic treatment when the sensitivity pattern of the responsible germ is unavailable. In the light of the results we can conclude that amoxycillin-clavulanic acid, first generation cephalosporins and fosfomycin show a good activity in vitro, and should be considered as empirical treatments for infections of the urinary tract.
