Multiple high-risk HPV genotypes are grouped by type and are associated with viral load and risk factors.

Investigating whether high-risk human papillomavirus (HR-HPV) types tend to become grouped in a particular way and whether factors are associated with such grouping is important for measuring the real impact of vaccination. In total, 219 women proving positive for HPV as detected by real-time PCR were included in the study. Each sample was analysed for detecting and quantifying six viral types and the hydroxymethylbilane synthase gene. Multiple correspondence analysis led to determining grouping patterns for six HR-HPV types and simultaneous association with multiple variables and whether viral load was related to the coexistence of other viral types. Two grouping profiles were identified: the first included HPV-16 and HPV-45 and the second profile was represented by HPV-31, HPV-33 and HPV-58. Variables such as origin, contraceptive method, births and pregnancies, educational level, healthcare affiliation regime, atypical squamous cells of undetermined significance and viral load were associated with these grouping profiles. Different socio-demographic characteristics were found when coinfection occurred by phylogenetically related HPV types and when coinfection was due to non-related types. Biological characteristics, the number of viral copies, temporality regarding acquiring infection and competition between viral types could influence the configuration of grouping patterns. Characteristics related to women and HPV, influence such interactions between coexisting HPV types reflecting the importance of their evaluation.

Inferring Plasmodium vivax protein biology by using omics data.

Deciphering Plasmodium vivax biology has long been a challenge for groups working on this parasite, mainly due to the complications involved in propagating it in vitro. However, adapting P. vivax strains in non-human primates and the arrival of high-performance analysis methods has led to increased knowledge regarding parasite protein composition and the ability of some molecules to trigger an immune response or participate in protein-protein interactions. This review describes the state of the art concerning proteomics-, immunomics- and interatomics-related P. vivax omic studies, discussing their potential use in developing disease control methods.

[Recovering lost vaccine coverage due to COVID-19 pandemic]. / Recuperando las coberturas vacunales perdidas en la pandemia de COVID-19.

The 2019 coronavirus disease pandemic can have an alarming impact on vaccination coverage. WHO, UNICEF and Gavi warn that at least 80 million children under the age of 1 are at risk of contracting diseases such as diphtheria, measles and polio due to the interruption of routine immunization and the temporary suspension of 93 campaigns of large-scale vaccination.In Spain, a new healthcare scenario, which prioritizes telematics over in person, fear of contagion by going to health centers, and recommendations for physical distance and restricted mobility, reduce attendance at primary care centers. Despite recommendations established by the health authorities, vaccination coverage has decreased in all Autonomous Communities between 5% and 60%, depending on the age and type of vaccine. School vaccinations have been suspended and only vaccination of pregnant women against tetanus, diphtheria and pertussis has been maintained. The decrease has been more evident for non gratuity vaccines: the first dose of meningococcal vaccine B has decreased by 68.4% in the Valencian Community, and Andalusia has observed a 39% decrease in the total doses of this vaccine and of 18% for that of rotavirus.The recovering of vaccinations should be planned, organized and carried out in the shortest possible time.This article discusses some aspects of the recovery of vaccination coverage for different groups: children, adolescents and adults, and patients at risk and in special situations.

[Recommendations of the Spanish Society for Pediatric Infectious Diseases (SEIP) on the management of drug-resistant tuberculosis]. / Documento de consenso de la Sociedad Española de Infectología Pediátrica sobre la tuberculosis resistente a fármacos.

Drug resistant tuberculosis (TB-R), and in particular, multidrug resistant tuberculosis (MDR-TB) is a global public health problem, as well as a problem in our country. Cases of TB-R and MDR-TB have increased mainly in HIV, immigrant and socially disadvantaged populations, but a notable increase in the general population has also been observed. This aspect reinforces the need for a systematic study of sensitivity of all the isolates in a reference laboratory to optimally guide the treatment. Children are especially vulnerable to this severe disease due to the limited knowledge of second line anti-tuberculous drugs, in terms of their pharmacokinetic data, optimal doses, or their long term toxicity, all this eventually resulting in the compassionate use of drugs. Another aspect which further complicates the management of R-TB in children is the limited yield of cultures, which frequently leads to clinician designing drug combinations according to the sensitivity of the initial strain. The epidemiological pattern in our country has currently changed. There is a reported increase in isoniazid-resistant strains; therefore, a four drugs regime is mandatory for the initial period in children, until reliable sensitivity results are available. Treatment should be directly observed or at least supervised by paediatricians. The management of latent infections or exposure to a resistant TB case also requires an accurate, strict and prolonged supervision by expert paediatricians. Authorities and health care professionals who deal with TB should be prepared to face this new phenomenon with appropriate measures. The knowledge of second line drugs for children, as well as mechanisms to ensure the therapeutic adherence and long term control of disease, are essential.

[Major histocompatibility complex class II deficiency]. / Déficit de expresión de moléculas de clase II del complejo mayor de histocompatibilidad.

Major histocompatibility complex class II deficiency is an autosomal recessive primary combined immunodeficiency. The prevalence of this deficiency is highest in Mediterranean areas, especially north Africa. Early diagnosis is essential due to high mortality in the first 2 years of life and the possibility of bone marrow transplantation. We report four cases of major histocompatibility complex class II deficiency and describe their epidemiologic and clinical characteristics, diagnostic tests, treatment and outcome.

The Aotus nancymaae erythrocyte proteome and its importance for biomedical research.

The Aotus nancymaae species has been of great importance in researching the biology and pathogenesis of malaria, particularly for studying Plasmodium molecules for including them in effective vaccines against such microorganism. In spite of the forgoing, there has been no report to date describing the biology of parasite target cells in primates or their biomedical importance. This study was thus designed to analyse A. nancymaae erythrocyte protein composition using MS data collected during a previous study aimed at characterising the Plasmodium vivax proteome and published in the pertinent literature. Most peptides identified were similar to those belonging to 1189 Homo sapiens molecules; >95% of them had orthologues in New World primates. GO terms revealed a correlation between categories having the greatest amount of proteins and vital cell function. Integral membrane molecules were also identified which could be possible receptors facilitating interaction with Plasmodium species. The A. nancymaae erythrocyte proteome is described here for the first time, as a starting point for more in-depth/extensive studies. The data reported represents a source of invaluable information for laboratories interested in carrying out basic and applied biomedical investigation studies which involve using this primate. SIGNIFICANCE: An understanding of the proteomics characteristics of A. nancymaae erythrocytes represents a fascinating area for research regarding the study of the pathogenesis of malaria since these are the main target for Plasmodium invasion. However, and even though Aotus is one of the non-human primate models considered most appropriate for biomedical research, knowledge of its proteome, particularly its erythrocytes, remains unknown. According to the above and bearing in mind the lack of information about the A. nancymaae species genome and transcriptome, this study involved a search for primate proteins for comparing their MS/MS spectra with the available information for Homo sapiens. The great similarity found between the primate's molecules and those for humans supported the use of the monkeys or their cells for continuing assays involved in studying malaria. Integral membrane receptors used by Plasmodium for invading cells were also found; this required timely characterisation for evaluating their therapeutic role. The list of erythrocyte protein composition reported here represents a useful source of basic knowledge for advancing biomedical investigation in this field.

[Immunisation schedule of the Spanish Association of Paediatrics: 2016 recommendations]. / Calendario de vacunaciones de la Asociación Española de Pediatría (CAV-AEP): recomendaciones 2016.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) annually publishes the immunisation schedule which, in our opinion, estimates optimal for children resident in Spain, considering available evidence on current vaccines. We acknowledge the effort of the Ministry of Health during the last year in order to optimize the funded unified Spanish vaccination schedule, with the recent inclusion of pneumococcal and varicella vaccination in early infancy. Regarding the funded vaccines included in the official unified immunization schedule, taking into account available data, CAV-AEP recommends 2+1 strategy (2, 4 and 12 months) with hexavalent (DTPa-IPV-Hib-HB) vaccines and 13-valent pneumococcal conjugate vaccine. Administration of Tdap and poliomyelitis booster dose at the age of 6 is recommended, as well as Tdap vaccine for adolescents and pregnant women, between 27-36 weeks gestation. The two-dose scheme should be used for MMR (12 months and 2-4 years) and varicella (15 months and 2-4 years). Coverage of human papillomavirus vaccination in girls aged 11-12 with a two dose scheme (0, 6 months) should be improved. Information for male adolescents about potential beneficial effects of this immunisation should be provided as well. Regarding recommended unfunded immunisations, CAV-AEP recommends the administration of meningococcal B vaccine, due to the current availability in Spanish communitary pharmacies, with a 3+1 scheme (3, 5, 7 and 13-15 months). CAV-AEP requests the incorporation of this vaccine in the funded unified schedule. Vaccination against rotavirus is recommended in all infants. Annual influenza immunisation and vaccination against hepatitis A are indicated in population groups considered at risk.

[Drowning in pediatric patients]. / Ahogamientos y casi ahogamientos en niños.

OBJECTIVE: Immersion accidents are still an important cause of morbidity and mortality in children. We performed a retrospective study to identify the prognostic factors associated with outcome in children who experience near-drowning, which could serve to guide decision-making. Our data were compared with other published data. PATIENTS AND METHODS: The medical records of children treated for near-drowning in our hospital from January 1995 to April 2003 were reviewed. The data analyzed referred to the patient, the accident, the patient's clinical status in the emergency unit, the unit to which the patient was admitted, and outcome. RESULTS: Sixty-two patients were included. Of these, outcome was bad in 12 (death in seven and irreversible sequelae in five). Statistically significant predictors of bad prognosis were age > or = 4 years, female sex, immersion time > or = 5 min, cyanosis in the emergency room, cardiac arrest, apnea or severe distress, hypothermia (core temperature < 35 degrees C), metabolic acidosis (pH < or = 7.10) and neurologic damage (Glasgow coma Scale score 3; Conn C; nonreactive and mydriatic pupils) on arrival at the hospital. CONCLUSIONS: Outcome is closely related to the patient's clinical status on arrival at the hospital. Although data that can serve as a guide to the final outcome of the nearly-drowned patient are available, early models to predict the final clinical results of each case, which could be used to guide initial resuscitation and subsequent treatment, are lacking.

Determining the Plasmodium vivax VCG-1 strain blood stage proteome.

Plasmodium vivax is the second most prevalent parasite species causing malaria in humans living in tropical and subtropical areas throughout the world. There have been few P. vivax proteomic studies to date and they have focused on using clinical isolates, given the technical difficulties concerning how to maintain an in vitro culture of this species. This study was thus focused on identifying the P. vivax VCG-1 strain proteome during its blood lifecycle through LC-MS/MS; this led to identifying 734 proteins, thus increasing the overall number reported for P. vivax to date. Some of them have previously been related to reticulocyte invasion, parasite virulence and growth and others are new molecules possibly playing a functional role during metabolic processes, as predicted by Database for Annotation, Visualization and Integrated Discovery (DAVID) functional analysis. This is the first large-scale proteomic analysis of a P. vivax strain adapted to a non-human primate model showing the parasite protein repertoire during the blood lifecycle. Database searches facilitated the in silico prediction of proteins proposed for evaluation in further experimental assays regarding their potential as pharmacologic targets or as component of a totally efficient vaccine against malaria caused by P. vivax. BIOLOGICAL SIGNIFICANCE: P. vivax malaria continues being a public health problem around world. Although considerable progress has been made in understanding genome- and transcriptome-related P. vivax biology, there are few proteome studies, currently representing only 8.5% of the predicted in silico proteome reported in public databases. A high-throughput proteomic assay was used for discovering new P. vivax intra-reticulocyte asexual stage molecules taken from parasites maintained in vivo in a primate model. The methodology avoided the main problem related to standardising an in vitro culture system to obtain enough samples for protein identification and annotation. This study provides a source of potential information contributing towards a basic understanding of P. vivax biology related to parasite proteins which are of significant importance for the malaria research community.

[Community acquired pneumonia in children: Outpatient treatment and prevention]. / Neumonía adquirida en la comunidad: tratamiento ambulatorio y prevención.

There have been significant changes in community acquired pneumonia (CAP) in children in the last decade. These changes relate to epidemiology and clinical presentation. Resistance to antibiotics is also a changing issue. These all have to be considered when treating CAP. In this document, two of the main Spanish pediatric societies involved in the treatment of CAP in children, propose a consensus concerning therapeutic approach. These societies are the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases. The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) has also been involved in the prevention of CAP. An attempt is made to provide up-to-date guidelines to all paediatricians. The first part of the statement presents the approach to ambulatory, previously healthy children. We also review the prevention with currently available vaccines. In a next second part, special situations and complicated forms will be addressed.

[Community acquired pneumonia in children: Treatment of complicated cases and risk patients. Consensus statement by the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Chest Diseases (SENP)]. / Neumonía adquirida en la comunidad: tratamiento de los casos complicados y en situaciones especiales. Documento de consenso de la Sociedad Española de Infectología Pediátrica (SEIP) y Sociedad Española de Neumología Pediátrica (SENP).

The incidence of community-acquired pneumonia complications has increased during the last decade. According to the records from several countries, empyema and necrotizing pneumonia became more frequent during the last few years. The optimal therapeutic approach for such conditions is still controversial. Both pharmacological management (antimicrobials and fibrinolysis), and surgical management (pleural drainage and video-assisted thoracoscopic surgery), are the subject of continuous assessment. In this paper, the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases have reviewed the available evidence. Consensus treatment guidelines are proposed for complications of community-acquired pneumonia in children, focusing on parapneumonic pleural effusion. Recommendations are also provided for the increasing population of patients with underlying diseases and immunosuppression.

[Immunisation schedule of the Spanish Association of Paediatrics: 2015 recommendations]. / Calendario de vacunaciones de la Asociación Española de Pediatría: recomendaciones 2015.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on the safety, effectiveness and efficiency of current vaccines, including levels of recommendation. In our opinion, this is the optimal vaccination calendar for all children resident in Spain. Regarding the vaccines included in the official unified immunization schedule, the Committee emphasizes the administration of the first dose of hepatitis B either at birth or at 2 months of life; the recommendation of the first dose of MMR and varicella vaccine at the age of 12 months, with the second dose at the age of 2-3 years; DTaP or Tdap vaccine at the age of 6 years, followed by another Tdap booster dose at 11-12 years old; Tdap strategies for pregnant women and household contacts of the newborn, and immunization against human papillomavirus in girls aged 11-12 years old with a 2 dose scheme (0, 6 months). The Committee reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule, the same as it is being conducted in Western European countries. The recently authorised meningococcal B vaccine, currently blocked in Spain, exhibits the profile of a universal vaccine. The Committe insists on the need of having the vaccine available in communitary pharmacies. It has also proposed the free availability of varicella vaccines. Their efectiveness and safety have been confirmed when they are administred from the second year of life. Vaccination against rotavirus is recommended in all infants. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A.

[Vaccination against meningococcal B disease. Public statement of the Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP)]. / Vacunación frente al meningococo B. Posicionamiento del Comité Asesor de Vacunas de la Asociación Española de Pediatría.

Meningococcal invasive disease, including the main clinical presentation forms (sepsis and meningitis), is a severe and potentially lethal infection caused by different serogroups of Neisseria meningitidis. Meningococcal serogroup B is the most prevalent in Europe. Most cases occur in children, with a mortality rate of 10% and a risk of permanent sequelae of 20-30% among survivors. The highest incidence and case fatality rates are observed in healthy children under 2-3 years old, followed by adolescents, although it can occur at any age. With the arrival in Spain of the only available vaccine against meningococcus B, the Advisory Committee on Vaccines of the Spanish Association of Paediatrics has analysed its preventive potential in detail, as well as its peculiar administrative situation in Spain. The purpose of this document is to publish the statement of the Committee as regards this vaccination and the access to it by the Spanish population, taking into account that it has been only authorized for people at risk. The vaccine is available free in the rest of Europe for those who want to acquire it, and in some countries and regions it has been introduced into the systematic immunisation schedules. The Committee considers that Bexsero® has a profile of a vaccine to be included in the official schedules of all the Spanish autonomous communities and insists on the need for it to be available in pharmacies for its administration in all children older than 2 months.

Neonatal hyperthyroidism in infants of mothers previously thyroidectomized due to Graves' disease.

Neonatal hyperthyroidism generally arises as a result of active maternal Graves' disease via transplacental passage of thyroid stimulating immunoglobulins (TSI). On occasions, production of these antibodies may continue after thyroid ablation, either surgically or with radioiodine therapy. We present data concerning three patients (two of them twins) whose mothers had previously undergone near-total thyroidectomy prior to conception. Two of the neonates had neonatal hyperthyroidism due to persistence of TSI in the mother, and the third due to relapse of the maternal Graves' disease during pregnancy. We recommend monitoring

[Prevention of serogroup B meningococcal disease using a four-component vaccine]. / Prevención de la enfermedad meningocócica por el serogrupo B mediante una vacuna de 4 componentes.

INTRODUCTION: Meningococcal disease is an infection caused by Neisseria meningitidis, and those of serogroup B are currently the most predominant. It has been difficult to create effective vaccines for this serogroup in order to modify or reduce its morbidity. The aim of this study was to review existing data on the new vaccine 4CMenB and its potential contribution to the prevention of this infection. METHODS: A panel of 12 experts (from Pediatrics, Public Health and Vaccinology) conducted a literature search and prioritized 74 publications. A review of the vaccine was then prepared, which was discussed in a meeting and subsequently validated by e-mail. RESULTS: 4CMenB vaccine, based on four components (NadA, fHbp, NHBA and OMVnz), was designed by reverse vaccinology. The Meningococcal Antigen Typing System (MATS) shows a potential of 70-80% coverage of the strains in Europe. Clinical trials show that the vaccine is safe and immunogenic in infants, children, adolescents, and adults, and induces an anamnestic response. The incidence of fever is similar to systemic vaccines administered alone, but higher when co-administered with them, although the fever pattern is predictable and self-limited. It is compatible with the Spanish routine vaccines, and can be administered simultaneously with the currently available hexavalent and pentavalent vaccines, as well as the pneumococcal conjugate vaccine. CONCLUSIONS: The 4CMenB vaccine is the only strategy currently available to prevent meningococcal disease caused by serogroup B.

[Immunisation schedule of the Spanish Association of Paediatrics: 2014 recommendations]. / Calendario de vacunaciones de la Asociación Española de Pediatría: recomendaciones 2014.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on safety, effectiveness and efficiency of vaccines. The present schedule includes levels of recommendation. We have graded, as routine vaccinations, those that the CAV-AEP consider all children should receive; as recommended those that fit the profile for universal childhood immunisation and would ideally be given to all children, but that can be prioritised according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in special situations. Immunisation schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Based on the latest epidemiological trends, CAV-AEP recommends the administration of the first dose of MMR and varicella vaccines at age 12 months, with the second dose at age 2-3 years; the administration of DTaP or Tdap vaccine at age 4-6 years, always followed by another Tdap dose at 11-12 years; and the three meningococcal C scheme at 2 months, 12 months and 12 years of age. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-12 years must be increased. Universal vaccination against varicella in the second year of life is an effective strategy, and the immediate public availability of the vaccine is requested in order to guarantee the right of healthy children to be vaccinated. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. The recently authorised meningococcal B vaccine has opened a chapter of hope in the prevention of this disease. In anticipation of upcoming national and international studies, the Committee recommends the vaccine for the control of disease outbreaks, and insists on the need to be available in pharmacies. Finally, it emphasises the need to bring incomplete vaccinations up to date following the catch-up immunisation schedule.

Invasive disease caused by Haemophilus parainfluenzae III in a child with uropathy.

Urinary tract infections (UTIs) caused by Haemophilus parainfluenzae represent a very small percentage of this kind of pathology in children, and it has scarcely been described in the medical literature. According to previous studies of over 800 urine samples in children under 15 years old, a decrease of 50% (from 0.13% to 0.07%) is estimated in its occurrence over the last two decades. This can be explained by the early detection of UTIs and their early empirical treatment, because this micro-organism shows high sensitivity to antibiotics. Also, the culture media in which this bacterium grows are not included in most current protocols. Here we report a case of a UTI caused by H. parainfluenzae in a 4-year-old boy.

[Universal immunisation against influenza in paediatrics, yes or no?]. / Vacunación antigripal universal en pediatría, ¿sí o no?

INTRODUCTION: The recommendations on influenza vaccination are not homogeneous between countries, with striking differences between the current recommendations in United States and Europe. OBJECTIVE: The objective of the study is to determine the efficacy, effectiveness and safety of the current flu vaccine (trivalent inactivated vaccine and adapted to the cold [LAIV] live virus vaccine) in healthy children, and to try and answer the following question: universal immunization against influenza in Paediatrics, yes or no? MATERIAL AND METHODS: A scheme of work based on the five standard steps of evidence or science-based medicine was used: 1) question, 2) search, 3) valuation, 4) applicability and 5) adequacy. RESULTS: Nine systematic reviews, published between 2005 and 2012, were selected that answered our clinical question, and which included the best available information (randomised clinical trials, cohort studies and case studies). CONCLUSIONS: The flu vaccine in childhood has the right cost - benefit - risk relationship. In all systematic reviews the efficacy of the flu vaccine varied between 58%-65%, and effectiveness between 28%-61%. Both efficacy and effectiveness increase with age, and there are limited studies showing sufficient evidence in children < 2 years. There are further areas to develop: more and better clinical trials on influenza vaccines in infants from 6 to 23 months; further research to achieve better influenza vaccines (addition of adjuvants, higher doses in children between 6 and 23 months, and study the LAIV vaccine in children between 6 and 23 months); and improvement in the prediction of vaccine strains responsible for the outbreak.

[Immunisation schedule of the Spanish Association of Paediatrics: 2013 recommendations]. / Calendario de vacunaciones de la Asociación Española de Pediatría: recomendaciones 2013.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on the safety, effectiveness and efficiency of vaccines. The present schedule includes levels of recommendation. We have graded as routine vaccinations those that the CAV-AEP consider all children should receive; as recommended those that fit the profile for universal childhood immunisation and would ideally be given to all children, but that can be prioritised according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in situations of risk. Immunisation schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Nevertheless, the achievement of a unified immunisation schedule in all regions of Spain is a top priority for the CAV-AEP. Based on the latest epidemiological trends, CAV-AEP follows the innovations proposed in the last year's schedule, such as the administration of the first dose of the MMR and the varicella vaccines at age 12 months and the second dose at age 2-3 years, as well as the administration of the Tdap vaccine at age 4-6 years, always followed by another dose at 11-14 years of age, preferably at 11-12 years. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-14 years, preferably at 11-12 years, must increase. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule. Universal vaccination against varicella in the second year of life is an effective strategy and therefore a desirable objective. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. Finally, it emphasizes the need to bring incomplete vaccinations up to date following the catch-up immunisation schedule.

[Gastroenteritis-related seizures: study of incidence and clinical analysis]. / Crisis convulsivas asociadas a gastroenteritis: estudio de incidencia y análisis clínico.

INTRODUCTION: Benign convulsions associated with gastroenteritis are now increasingly recognized as clinical condition to the extent that it has become an independent entity under the heading of non-epileptic situational seizures. The aim of this study is to determine the annual incidence in the reference population of our hospital and the clinical characterization of seizures associated to gastroenteritis, in the absence or presence of fever for comparison. PATIENTS AND METHOD: All seizures associated with gastroenteritis treated in our hospital were prospectively collected over a period of two calendar years. The children included were aged 6 months to 6 years with seizures in the context of gastroenteritis without electrolyte abnormalities, and divided into two groups, with and without fever. RESULTS: There were 14 cases from a reference population of 39,900 with a homogeneous semiological presentation. CONCLUSION: The annual incidence was estimated at 1/10 000 children for afebrile seizures associated with gastroenteritis. The clinical behaviour and the incidence of seizures associated with fever and gastroenteritis was similar, but with an appearance somewhat earlier from the onset of symptoms, and at a slightly higher age.
