Abstract
OBJECTIVE The aim of this study was to describe the lithogenic risk profile of pediatric patients with lithiasis. METHODS We retrospectively analyzed the metabolic studies in 24-hour urine samples in 47 pediatric patients with lithiasis. Biochemical determinations were made in blood and 24-hour urine. Oxalate calcium, brushite, struvite and uric acid salt saturations were calculated. 49 healthy children were used as a control group. RESULTS No significant differences were found in biochemical blood parameters between children with stones and the group without stones. Calciuria, uricosuria and phosphaturia, oxalate calcium, brushite and uric acid saturations were higher in lithiasic children. In the multivariate analysis, using a logistic regression model, we only found hypercalciuria as lithogenic risk factor. (OR = 1.96 p <0.002). CONCLUSIONS Urinary metabolic abnormalities and elevated salt saturations in urine are a frequent finding in children with urolithiasis, but in our study we only found hypercalciuria as an independent risk factor for the formation of lithiasis.

Abstract
OBJECTIVE The Childhood Asthma Control Test (c-ACT) is a validated tool for determining pediatric asthma control. However, it is not validated in the Spanish language in Spain. We evaluated the psychometric properties of the Spanish version of the Childhood Asthma Control Test (Sc-ACT) for assessing asthma control in children ages 4 to11. METHODS This national, multicentre, prospective study was conducted in Spain with asthmatic children and their caregivers. Patients were assessed at 3 visits (Baseline, 2 Weeks, and 4 Months). Clinical variables included: symptoms, exacerbations, FEV1, asthma classification, PAQLQ and PACQLQ questionnaire scores, and asthma control as perceived by physicians, patients and caregivers. The Sc-ACT feasibility, validity, reliability, and sensitivity to change were assessed. RESULTS A total of 394 children were included; mean (SD) time to complete the Sc-ACT was 5.3 (4.4) minutes. Sc-ACT score was correlated with asthma control as perceived by physician (-0.52), patient (-0.53), and caregiver (-0.51) and with the PAQLQ (0.56) and PACQLQ (0.55) scores. Sc-ACT was found to be significantly related to intensity and frequency of asthma symptoms. Cronbach alpha coefficient α was 0.81 and intraclass correlation coefficient was ≥0.85 for all of the items. The global effect size of Sc-ACT was 0.55. The cutoff point scores of 21 or higher indicated a good asthma control and their MCID was 4 points. CONCLUSION The Spanish version of the c-ACT was found to be a reliable and valid questionnaire for evaluating asthma control in Spanish-speaking children ages 4 to 11 in Spain.

Abstract
OBJECTIVES This study assesses the relationships between social context (family and inter-peer context), stress, and illness in 5-6-year-old children. METHODS To this end, data were collected on spontaneous social interpeer behavior; families provided data on stress, anxiety, and parental acceptance-rejection; and the children's pediatricians provided data relative to their health. Data on stress-related hormones (cortisol) were collected using saliva samples. RESULTS The results revealed that none of the variables examined were significantly related to illness development in the subjects in the sample group. Cortisol levels, however, were positively associated with a record of chronic or congenital illnesses, the manifestation of behaviors related to the search for leadership status in the group and the presence of stressful events in the family environment. CONCLUSIONS Despite finding no relationship between children's level of adrenocortical activity and the contracting or contingent development of diseases, we did find that chronic/congenital diseases may constitute a source of early stress in childhood. Certain conditions of uncertainty in the social context (family and interpeer) also seem to constitute different sources of stress.

Abstract
BACKGROUND The management of anaphylaxis in pediatric emergency units (PEU) is sometimes deficient in terms of diagnosis, treatment, and subsequent follow-up. The aims of this study were to assess the efficiency of an updated protocol to improve medical performance, and to describe the incidence of anaphylaxis and the safety of epinephrine use in a PEU in a tertiary hospital. METHODS We performed a before-after comparative study with independent samples through review of the clinical histories of children aged <14 years old diagnosed with anaphylaxis in the PEU according to the criteria of the European Academy of Allergy and Clinical Immunology (EAACI). Two allergists and a pediatrician reviewed the discharge summaries codified according to the International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) as urticaria, acute urticaria, angioedema, angioneurotic edema, unspecified allergy, and anaphylactic shock. Patients were divided into two groups according to the date of implantation of the protocol (2008): group A (2006-2007; the period before the introduction of the protocol) and group B (2008-2009; after the introduction of the protocol). We evaluated the incidence of anaphylaxis, epinephrine administration, prescription of self-injecting epinephrine (SIE), other drugs administered, the percentage of admissions and length of stay in the pediatric emergency observation area (PEOA), referrals to the allergy department, and the safety of epinephrine use. RESULTS During the 4 years of the study, 133,591 children were attended in the PEU, 1673 discharge summaries were reviewed, and 64 cases of anaphylaxis were identified. The incidence of anaphylaxis was 4.8 per 10,000 cases/year. After the introduction of the protocol, significant increases were observed in epinephrine administration (27% in group A and 57.6% in group B) (p = 0.012), in prescription of SIE (6.7% in group A and 54.5% in group B) (p = 0.005) and in the number of admissions to the PEOA (p = 0.003) and their duration (p = 0.005). Reductions were observed in the use of corticosteroid monotherapy (29% in group A, 3% in group B) (p = 0.005), and in patients discharged without follow-up instructions (69% in group A, 22% in group B) (p = 0.001). Thirty-three epinephrine doses were administered. Precordial palpitations were observed in one patient. CONCLUSION The application of the anaphylaxis protocol substantially improved the physicians' skills to manage this emergency in the PEU. Epinephrine administration showed no significant adverse effects.

Abstract
INTRODUCTION Asthma is the most common chronic disease in childhood, reduces the quality of life of children and their families, and produces high social and health care costs. In Spain, the cost of managing paediatric asthma is unknown. OBJECTIVE To estimate the cost of managing paediatric asthma in Spain and to examine its variability depending on asthma severity. PATIENTS AND METHODS The cost of asthma in children under 16 years in 2008 was estimated by building a costs assessment model including the factors that influence the cost of asthma in children: prevalence, distribution of disease severity, age, frequency of resources use depending on severity, and the cost of each resource. A sensitivity analysis was conducted to evaluate the underlying uncertainty depending on the variability of the estimators of resource use, the unit cost of each resource, and the prevalence. RESULTS According to the model, the total cost of paediatric asthma in Spain is around 532 million euros, with a range of 392 to 693 million euros. Direct costs (health care costs) represent 60% of the total costs, and indirect costs (carer time), 40%. The mean annual cost per child with asthma is 1,149 euros, ranging from 403 euros for the mildest category of the disease to 5,380 euros for the most severe. CONCLUSIONS The cost of paediatric asthma in Spain is very high and depends on disease severity. Although the most important costs are for the health care system, indirect costs are not negligible.

Abstract
BACKGROUND The aim of this study was to investigate the association among a validated symptom-based questionnaire for asthma control in children (CAN), forced expiratory volume in 1 sec (FEV(1)), and fractional exhaled nitric oxide (FE(NO)). METHODS Observational cross-sectional study was performed in a consecutive sample of asthmatic children aged between 7 and 14 years old from December 2007 to February 2008. FE(NO) was measured with a portable electrochemical analyzer and forced spirometry was performed according to American Thoracic Society/European Respiratory Society. The CAN questionnaire was completed by the parents (aged <9 years old) or by the children (> or = 9 years old). The strength of the association among FEV(1), FE(NO), and CAN questionnaire was studied using Spearman's rho, and the degree of agreement for asthma control among FEV(1), FE(NO), and CAN questionnaire, with classification of these variables according to values of normality, was studied using Pearson's chi(2) test and Cohen's kappa (KC). RESULTS We studied 268 children, mean age 9.7 +/- 2.1 years. Significant correlations were found between FE(NO) and CAN (r = 0.2), between FEV(1) and CAN (r = -0.3), and between FE(NO) and FEV(1) (r = -0.12). On classifying the variables according to values of normality, no agreement was found to establish the degree of asthma control between FE(NO) and CAN (KC = 0.18, chi(2) Pearson = 9.63); between FEV(1) and CAN (KC = 0.29, chi(2) = 38.5); or between FE(NO) and FEV(1) (KC = 0.07, chi(2) = 4.9). CONCLUSIONS The association among the three measurement instruments used to assess asthma control (FEV(1), FE(NO), and CAN) was weak. These are instruments that quantify variables that influence asthma in different ways, in this sense, none can be used instead of another in asthma management although they are complementary.

Abstract
Primary lung tumours are uncommon in childhood. Among these tumours, endobronchial masses are even less common and, among benign tumours, inflammatory pseudotumours and hamartomas have the highest incidence in children. We present the case of a 2.5-year-old girl with a left endobronchial chondromesenchymal hamartoma with obstruction of 90% of the bronchial lumen. Complete resection of the endobronchial mass was performed by rigid bronchoscopy and application of topical mitomycin C. After tumour resection and a 12-month follow-up, the patient has shown a favourable outcome with immediate disappearance of respiratory symptoms. Successive fibreoptic bronchoscopies have shown no residual tumour.

Abstract
The 3 year-old group of children has an increased incidence and prevalence of recurrent wheezing episodes. There are different subgroups, who give different inflammatory responses to different triggering agents, and subgroups that differ in aetiopathology and immunopathology. Current diagnostic methods (exhaled nitric oxide in multiple breaths, nitric oxide in exhaled air condensate, induced sputum, broncho-alveolar lavage and endo-bronchial biopsy), enable the inflammatory pattern to be identified and to give the most effective and safe treatment. The various therapeutic options for treatment are reviewed, such as inhaled glucocorticoids when the inflammatory phenotype is eosinophilic, and leukotriene receptor antagonists, when the inflammatory phenotype is predominantly neutrophilic. In accordance with the current recommendations, for the diagnosis as well as for the therapy initiated in children of this age, they must be regularly reviewed, so that if the benefit is not clear, the treatment must be stopped and an alternative diagnosis and treatment considered. The start of treatment should be determined depending on the intensity and frequency of the symptoms, with the aim of decreasing morbidity and increasing the quality of life of the patient.

Abstract
Different studies show that mental retardation affects 1-3% of the population, and in about 50 % of the cases the aetiology is unknown. The uncertainty on the aetiology, and recurrence, means that prevention of mental retardation can have serious, therapeutic, social, and even economic repercussions. The key is to obtain an accurate diagnosis, proving a clinical hypothesis by the accomplishment of the most suitable genetic tests. Due to the increasing development of the technology in the field of the genetics, and the availability of new tests, this article reviews the criteria established in the practice guidelines from different scientific societies (paediatric, neurological and genetic) with respect to their use in diagnosis and integrates them from the point of view of their use in mental retardation and developmental delay.

Abstract
OBJECTIVE To develop and validate a questionnaire to assess asthma control in children (CAN). DESIGN Two versions of the CAN (for carers and children) were developed. Both versions were validated in an observational, prospective, multicenter study performed in 38 hospital outpatient clinics throughout Spain. Four hundred fifteen patients and their carers agreed to participate. Of these, 414 patients under 14 years old with frequent episodic or persistent (moderate to severe) asthma completed the questionnaire on 3 occasions (baseline, week 2, and week 12). For patients aged 2-8 the questionnaire was only completed by the carers, but for patients aged 9-14 the questionnaire was completed by the carers and the children. Clinician ratings of asthma control were used as a gold standard to assess the sensitivity, specificity, PPV and NPV of the new measure. RESULTS Evaluable responses were obtained from 215 carers for children aged 2-8 years and 199 children aged 9-14 years, and their parents. Using a questionnaire total score cut-off of 8 the patient version had a sensitivity of 76.3% and a specificity of 62.9%. For carer version these values were 73% and 69.7%, respectively. A cut point of 8 was selected to maximize the screening accuracy of the CAN questionnaire. Effect sizes in patients with clinician-rated improvements in asthma control were 0.33 and 0.57 for the carer and child versions, respectively. CONCLUSIONS The screening accuracy and validity of the CAN questionnaire make it suitable for use in research and clinical practice. The sensitivity and specificity were close to 70%, which is acceptable for the study objective: obtain a tool to measure the level of asthma control.

Abstract
OBJECTIVES To obtain a Spanish version of the TNO-AZL Preschool Children Quality of Life Questionnaire (TAPQOL) that would be both semantically and culturally equivalent to the original. MATERIAL AND METHODS The TAPQOL questionnaire was designed to measure health-related quality of life in children aged 3 months to 5 years and contains 43 questions distributed in 12 subdimensions. The Spanish version was obtained by using the forward/back-translation method with expert, bilingual translators. Cognitive debriefing interviews were carried out with the parents of healthy children and with those of children with respiratory disease. RESULTS During the adaptation phase, four items were modified after input from the authors of the original version to retain the meaning of the original. At the end of the adaptation process, 37 of the 43 items were classified as A, i.e. without difficulty in the adaptation. Four mothers and two fathers participated in the cognitive debriefing interviews. Four had secondary level education, and two had university level education. Their children were aged between 16 and 60 months. The average time taken to complete the questionnaire was 13.5 minutes. No comprehension problems regarding the questionnaire's content were found, and no items were modified after this phase of the study. The mothers of children with respiratory disease considered the questions related to their children's symptoms to be appropriate. CONCLUSIONS The Spanish version of the TAPQOL has proven to be acceptable and culturally equivalent to the original version. Future studies should investigate the psychometric properties of this questionnaire and compare them with those of the original version.

Abstract
BACKGROUND Measurement of fractional exhaled nitric oxide (FENO) is a non-invasive marker of eosinophilic airway inflammation that can be useful in asthma diagnosis and control, as well as in treatment monitoring. OBJECTIVE We studied the correlation between two techniques for measuring FENO: the chemiluminescence-based analyzer (NIOX, Aerocrine, Sweden) and a new portable electrochemical sensor-based analyzer (NIOX-MINO, Aerocrine). MATERIAL AND METHODS FENO was measured by the single breath on-line method. In all children, three consecutives measurements were obtained with NIOX, with a maximum of six attempts, and the arithmetic mean was calculated. Next, using NIOX-MINO, a single measurement was made successively in each of the children. The variables analyzed were sex, age, height, weight, diagnosis, treatment, NIOX-MINO value, mean of three values obtained with NIOX and the NO elimination rate (nL/min). For the statistical analysis, the Bland-Altman plot was used to compare the means and the differences between measurements of FENO from NIOX and NIOX-MINO. The agreement between the two analyzers was estimated by Cohen's Kappa statistic. RESULTS Thirty children were included, 14 (46.67%) boys and 16 (53.33%) girls. The mean age was 11.3+/-3.09 years. All of the children successfully performed the measurements with two analyzers. The relationship between the means and the differences in the values obtained with NIOX-MINO and NIOX were statistically significant (p<0.005). In addition, Cohen's Kappa statistic (0.78) suggested a high degree of agreement between the results obtained with the two devices. CONCLUSIONS The two analyzers, NIOX-MINO and NIOX, were not equivalent. There was good agreement between the FENO values measured with the two devices. Measurement of FENO with the portable electrochemical sensor-based analyzer (NIOX-MINO) is valid and feasible in children older than 5 years.

Abstract
OBJECTIVE To determine the current prevalence of asthma in children aged 6-12 years old in San Sebastian (Guipuzcoa, Spain). PATIENTS AND METHODS An observational, cross sectional study was performed in 6-12-year-old children in schools. The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was employed. Bronchial hyperresponsiveness was investigated using the free running test, with peak expiratory flow (PEF) measured with a peak flow meter as the main measurement. The ISAAC questionnaire (n = 919) was distributed to 460 boys (50.1%) and 459 girls (49.9%) with a mean age of 8 years (SD 1.87). The response rate to the questionnaire was 93 % (n = 855). Participation in the free running test was 90.8% (n = 835). A total of 89.88% of the children (n = 826) completed both tests. RESULTS The questionnaire of symptoms and signs compatible with asthma revealed a current prevalence of asthma of 25.56% (n = 216) and a cumulative prevalence of 25.44% (n = 85). Nocturnal asthma was found in 29.37% (n = 47) and severe asthma in 9.27% (n = 14). Bronchial hyperresponsiveness was found in 23% of the participants. An epidemiological diagnosis of asthma (asthma-related symptoms plus bronchial hyperresponsiveness) was made in 6.54%. CONCLUSIONS The current prevalence of asthma in 6-12-year-old schoolchildren in San Sebastian, determined through symptoms and signs compatible with asthma in the previous year and a positive free running test, is similar to that reported in other national studies.

Abstract
This population-based study evaluated the incidence of virologically confirmed influenza-related hospitalisation in children aged <5 years between July 2001 and June 2004 in a region of southern Europe. Forty-nine children with influenza virus infection were hospitalised. The annual hospitalisation rates per 1000 inhabitants for each period were 5.1, 0 and 7.3 for infants aged less than 6 months, 0.9, 0.2 and 0.9 for children aged 6-23 months, and 0.7, 0.1 and 0.8 for those aged 24-59 months. Most of the children were hospitalised in the epidemic waves caused by the influenza A/H3N2 virus and were previously healthy. This study supports the need to introduce measures to reduce the burden of disease due to influenza virus infection in young children. New vaccines or vaccination strategies that could be applied in infants should be developed.

Abstract
Palliative care is essential in the pediatric intensive care unit (PICU). Because of the mortality rates and the presence of life-threatening conditions in children admitted to the PICU, pediatricians must be prepared to provide palliative care independently of cure-directed therapies. The present article reviews certain issues, including the decision-making process in the PICU, psychosocial needs and susceptibility to burnout among PICU staff, and the emotions and attitudes of the staff when a child dies. We provide some guidelines on how to act when a child dies, how to meet with parents after the child's death and how to follow-up parental bereavement. Strategies that can help PICU pediatricians to cope with the numerous loses they experience are suggested.

Abstract
OBJECTIVE To study the etiological factors associated with erythema nodosum in children hospitalized between January 1985 and December 2003. MATERIAL AND METHODS We performed a retrospective, descriptive study through review of the medical records of children with a diagnosis of erythema nodosum (MBDS-ICD 9-CM, code 6952). Forty-five patients (27 boys and 18 girls) aged between 10 months and 14 years were studied. The following variables were analyzed: age, sex, associated symptoms, complementary investigations (blood count, erythrocyte sedimentation rate, throat swab, chest x-ray, Mantoux test, ASLO titer, stool culture, serology) and final diagnosis. RESULTS The most frequent etiology was tuberculosis (10 patients), followed by Salmonella enteritidis (7 patients), group A beta -hemolytic Streptococcus (3 patients), Salmonella typhimurium (2 patients), Campylobacter jejuni (2 patients), Yersinia enterocolitica (1 patient), infectious mononucleosis caused by Epstein Barr virus (1 patient), cat scratch disease (1 patient), BCG vaccination (1 patient), associated chronic hepatitis B infection (1 patient), and associated amoxicillin treatment (1 patient). Etiology was unknown in 15 patients. The last case of erythema nodosum associated with tuberculous infection dated back to 1991, after which the most frequent etiologic factors associated with erythema nodosum were gastrointestinal pathogens. CONCLUSIONS According to our results, the main etiological factor currently associated with erythema nodosum is gastrointestinal infection. Consequently, stool cultures, especially when there are associated gastrointestinal symptoms, are essential.

Abstract
OBJECTIVES To assess the efficacy and tolerability of oral deflazacort versus oral prednisolone in acute moderate asthma in children. PATIENTS AND METHODS We performed a prospective, randomized, parallel group trial of children aged 6 to 14 years old with a diagnosis of asthma who presented to the pediatric emergency department for moderate asthma exacerbation. All patients were administered short-acting beta2-adrenergic agonists. The intervention groups received either oral deflazacort (1.5 mg/kg) or prednisolone (1 mg/kg) for 7 days. The primary outcome measure was forced expiratory volume in 1 second (FEV1) and secondary outcome measures were pulmonary symptom score index, peak expiratory flow rate (PEFR), hospitalization rate and the use of rescue beta2-agonists. Patients were evaluated at the start of treatment (visit 1), on day 2 (visit 2) and on day 7 (visit 3). RESULTS Of the 54 children enrolled, two were hospitalized on visit 2 (one from each group). Baseline clinical data were similar in both groups: FEV1: 53 and 51 %; bronchodilator test: 119 and 121 %; PEFR: 169 and 165 L/min; symptom score: 6 and 6.5 for the deflazacort and prednisolone groups, respectively. On visit 2, all measures improved: FEV1: 122.2 and 126.5 % (p < 0.05); PEFR: 164 and 149 L/min (p < 0.05); symptom score: -4.4 and -3.8 (p < 0.05), without significant differences between groups. On visit 3 all variables continued to show improvement: FEV1: 133.2 and 132.5 % (p < 0.05); PEFR: 1115.7 and 187.6 L/min (p < 0.05); symptom score: -5.4 and -5.9 (p < 0.05), without significant differences between groups. No adverse effects were reported. CONCLUSIONS Deflazacort and prednisolone show similar efficacy in improving pulmonary function and in producing clinical improvement in the management of acute moderate asthma in children.

Abstract
BACKGROUND The clinical manifestations of influenza virus are fairly nonspecific and are similar to those of other viral infections, respiratory processes due to other causes and even septic disease in neonates. Few studies have been performed of the clinical characteristics of influenza virus infection in hospitalized children. OBJECTIVE To evaluate the clinical characteristics of children hospitalized for influenza virus infection in four consecutive epidemic waves (2000-2004). MATERIAL AND METHODS We retrospectively reviewed the medical records of children hospitalized for influenza A and B virus infection confirmed by cell culture and polymerase chain reaction. Age, sex, symptoms on admission, complementary investigations, diagnosis and outcome were evaluated. RESULTS Eighty-four children were hospitalized, of which 74 had influenza virus type AH3, five had influenza virus type AH1 and five had influenza B virus. A total of 42.8 % were aged less than 6 months. The main symptoms were fever (75 patients), cough (56 patients) and ENT involvement (53 patients). The most frequent causes of admission were febrile syndrome (75 patients), bronchiolitis (19 patients), pneumonia (13 patients) and bronchitis (8 patients). In 21 patients viral or bacterial coinfection was found, the most frequent of which was respiratory syncytial virus (10 patients). Few differences were found among age groups except for pneumonia and prolonged fever (more frequent in children older than 6 months) and lymphocytosis (in children younger than 6 months). The greatest number of complementary investigations in younger children was performed for acute febrile syndrome in neonates aged less than 6 months. Risk factors for hospitalization were found in only three children, all of whom were older than 6 months. Outcome was favorable in all children. CONCLUSIONS Influenza virus infection in hospitalized children is most frequent in previously healthy neonates with fever and nonspecific signs and symptoms that are similar to those of other infectious processes. Specific microbiological diagnostic techniques are required for an early diagnosis. Healthy infants aged less than 24 months are most at risk for hospitalization for influenza virus infection.

Abstract
The most common causes of persistent cough are upper respiratory tract disease (postnasal drip syndrome, infections) and asthma. In the last year, six patients (four boys and two girls), aged 7-12 years old, with a diagnosis of hard-to-manage asthma and/or persistent cough were referred to our department. All the patients had undergone treatment with multiple drugs for long periods without favorable clinical response. The findings of physical examination, radiology, basal pulmonary function and post-bronchodilation and fibrobronchoscopy were normal. Organic disease was ruled out and a psychiatric evaluation was performed. Intelligence quotient was in the lower normal range and generalized anxiety order was identified, thus establishing a diagnosis of psychogenic cough. Treatment consisted of relaxation techniques and psychopedagogic support with favorable outcome. To avoid diagnostic errors and inappropriate treatment, psychogenic cough should be included in the differential diagnosis of persistent cough and hard-to-manage asthma.

Abstract
OBJECTIVES To assess the epidemiological characteristics of invasive pneumococcal disease (IPD) in children in Gipuzkoa (Spain) as well as the serotype distribution among these episodes and to analyze the potential impact of new conjugate vaccines. METHODS We performed a retrospective study of cases of IPD in the pediatric population (< 15 years) between 1981 and 2001. Patients were included if blood, cerebrospinal, joint or peritoneal fluid isolates were culture-positive for Streptococcus pneumoniae. RESULTS One hundred twenty-nine episodes (30 meningitis, 39 bacteremic pneumonia, 7 peritonitis, 1 arthritis and 52 bacteremia without focus) were identified. The incidence of IPD in children increased throughout the study period and from 1999-2001 was 12.6 cases per 100,000/ year in children aged < 15 years, 34.5 in those < 5 years, 48.4 in those < 2 years and 40.8 in infants < 2 months. The incidence of pneumococcal meningitis was similar throughout the study period (1981-2001): 1.3 in children aged < 15 years, 3.5 in those < 5 years, 8.1 in those < 2 years and 10.2 in infants < 2 months. From 1989 to 2001 mortality was 1 % (1/98 cases). The pneumococcal serotypes and serogroups present in the 7-valent vaccine accounted for 60.5 % and 70.9 % of the cases (9-valent vaccine: 70.2 % and 80.6 %; 11-valent vaccine: 76.6 % and 87.2 %). From 1999-2001, penicillin resistance was 35.4 % and erythromycin resistance was 38.7 %. CONCLUSIONS The incidence of IPD in children in Gipuzkoa has increased in the last few years, with rates similar to those in other European countries. Continued surveillance is required to assess the impact of the new conjugate vaccines on this infection.

Abstract
Authors report 49 patients bacteriologicallyly diagnosed of acute meningococcal infection collected during a 12 months period out of a series of 76 cases diagnosed on clinical grounds. "N. meningitidis" was found in 18 blood and 43 CSF cultures. 31 cases were of the B-group, one was A-group and 17 were not typed. All of them were sulphamide resistant. Hyperthermia with vomiting, cephalea, arthralgia and seizures were the initial symptoms. All patients showed pettechiae, purpura and/or ecchymoses. Endotoxic shock was diagnosed in 26,5% of the cases. In them systolic blood pressures were under p-5. Overall mortality was 14%, and that of endotoxic patients 53%. Therapeutic routines and chemoprophylaxis are reviewed.
