Eficacia y seguridad de las vacunas contra el SARS-CoV-2 / Efficacy and safety of SARS-CoV-2 vaccines

Ha habido un esfuerzo extraordinario, tanto técnico como económico, para producir vacunas eficaces. Las vacunas de las que existen datos de eficacia son las que han publicado resultados de la fase 3. Se resumen los datos más relevantes de estos ensayos clínicos agrupados por tipo de vacuna. Mientras que los datos de eficacia se obtienen en ensayos clínicos, la efectividad ha de medirse en la vida real, teniendo en cuenta que las vacunas se han empezado a implementar en España el 27 de diciembre de 2020. Las vacunas para prevenir la infección por SARS-CoV-2 parecen seguras y eficaces, con una calidad de la evidencia moderada. En el momento actual se ha vacunado de forma universal a la población adulta (primer grupo en tener evidencias de eficacia y seguridad vacunal) con las vacunas disponibles y según grupos de riesgo establecidos por el Ministerio de Sanidad, posteriormente se han ido incorporando otros grupos como embarazadas y adolescentes, y recientemente se ha incorporado el grupo de escolares entre 5 y 11 años tras la publicación de eficacia y seguridad vacunal en esta franja de edad de una de las vacunas autorizadas en la Unión Europea. A pesar de las limitaciones que presentan los ensayos clínicos, la situación de pandemia actual con gran amenaza para la salud pública y la gran pérdida de vidas que produce la enfermedad por SARS-CoV-2, hace que el balance riesgo beneficio sea favorable a la vacunación (AU)

There has been an extraordinary effort, technical as well as economic to produce effective vaccines. The vaccines with known effectivity data are those that have published phase 3 results. The most relevant data of these clinical trials are resumed here grouped by type of vaccine. While data on effectivity are obtained from clinical trials, the effectiveness must be measured in real life, considering that vaccines have been implemented in Spain since December 27, 2020. The vaccines to prevent SARS-CoV-2 infections seem safe and effective, with a moderate quality of the evidence. Currently, the adult population has been vaccinated (first age group with evidence of effectivity and safety) with the available vaccines and according to risk groups established by the Health Ministry, afterwards other groups have been added such as pregnant women and adolescents, and recently the schoolers 5 to 11 years after the publication of effectivity and safety in this age group of one of the vaccines authorized in the European Union. Despite the limitations of the published clinical trials, the current pandemic situation means a great public health threat and an enormous loss of lives due to SARS-CoV-2, which makes the risk benefit balance favorable to vaccination.

Ictiosis Lamelar autosómica recesiva: revisión de la literatura y caso clínico / Autosomal recessive lamellar ichthyosis: review of the literature and clinical case

Resumen Las ictiosis congénitas autosómicas recesivas (ICAR) son poco frecuentes a nivel mundial con una incidencia de 1:300,000 nacimientos, se caracterizan por trastornos de la queratinización, entre sus variantes engloban las formas no sindrómicas de ictiosis, como la ictiosis laminar (IL), la eritrodermiaictiosiforme congénita (EIC) y actualmente se incluyen la ictiosis arlequín, el bebé colodión autorresolutivo, el bebé colodión autorresolutivoacral y la ictiosis en traje de baño. Desde el punto de vista genético son heterogéneas, originadas por una mutación en el gen de la transglutaminasa 1 y se las haasociado a TGM1, ALOXE3, ALOX12B, NIPAL4, CYP4F22 y ABCA12. Clínicamente, la ictiosis se caracteriza principalmente por piel gruesa, escamas laminares adherentes con hendiduras profundas. En este trabajo pretende revisar los conocimientos actuales en el campo de las ICAR, incluyendo aspectos clínicos, histológicos, ultraestructurales, genético-moleculares, tratamiento,y también su manejo clínico.

Abstract The autosomal recessive congenital ichthyosis (ARCI) is a rare worldwide condition with an incidence of (1: 300,000 births), characterized by disorders of keratinization, among its variants encompass the non-syndromic forms of ichthyosis, such as laminar ichthyosis (IL) , congenital ichthyosiform erythroderma (EIC) and currently include harlequin ichthyosis, self-healing colodion baby, acral self-healing colodion baby and ichthyosis in swimsuits. From a genetic point of view, they're heterogeneous, originated by a mutation in the gene of transglutaminase 1 and associated with TGM1, ALOXE3, ALOX12B, NIPAL4, CYP4F22 and ABCA12. Clinically, ichthyosis is mainly characterized by thick skin, adherent lamellar scales with deep clefts. The aim of this work is to review the current knowledge in the field of ICAR, including clinical, histological, ultrastructural, genetic-molecular and therapeutic aspects as well as its clinical management.

Dermatitis atópica: Pitiriasis alba. A propósito de un caso / Atopic Dermatitis: Pityriasis Alba. A clinical case

RESUMEN La Pitiriasis alba es una enfermedad cutánea inespecífica de etiología desconocida, caracterizada por máculas hipocrómicas, redondeadas u ovaladas poco delimitadas y cubiertas con escamas finas que ocurren usualmente en la región facial de los niños. Fue descrita por Gilbert en 1860 y Fox en 1923, pero fue O'Farrell en 1956 quien propuso el nombre de Pitiriasis alba. La condición dermatológica con la que suele asociarse es la dermatitis atópica. La presencia de Pitiriasis alba fue definida como uno de los criterios menores para el diagnóstico de Dermatitis atópica, según Hanifin y Rajka en 1980. Sin embargo, también se presenta en 20-40% de los niños atópicos, sin evidencia de Dermatitis atópica, así como en individuos no atópicos. La disfunción de la barrera epitelial causada por mutaciones del gen de la filagrina, proteína estructural epidérmica, que forma parte del factor humectante natural, se considera un factor de riesgo emergente para la Dermatitis atópica severa de comienzo precoz. Se presenta un caso de Pitiriasis albaen el que fue necesaria terapia combinada tópica y vía oral, con evolución satisfactoria en 8 semanas de tratamiento.

SUMMARY Pityriasis Alba is a non-specific skin disease of unknown etiology characterized by hypochromic macules, rounded or oval, poorly defined and covered with fine scales that usually occur in the facial region of children. It was described by Gilbert in 1860 and Fox in 1923, but it was O'Farrell in 1956 who proposed the name Pityriasis alba. The dermatological condition with which it is usually associated is Atopic dermatitis. The presence of Pityriasis alba was defined as one of the minor criteria for the diagnosis of Atopic dermatitis, according to Hanifin and Rajka in 1980. However, it also occurs in 20-40% of atopic children, without evidence of Atopic dermatitis, as well as in non-atopic individuals. Epithelial barrier dysfunction caused by mutations of the filaggrin gene, epidermal structural protein, which is part of the natural humectant factor, is considered an emerging risk factor for severe early onset Atopic dermatitis. We present a case of Pityriasis alba where combined topical and systemic therapy was necessary with satisfactory evolution in 8 weeks of treatment.

SUMMARY Ringworm of the head (tinea capitis) is a frequent dermatophytosis of the scalp in children. In fact, it is the most common of all cutaneous mycosis in this age group worldwide, being very rare in adults. It has been considered an important public health problem for decades, of the factors associated are: poor personal hygiene, overcrowding and low socioeconomic level. The most frequently isolated etiologic agent was Microsporumcanis with 82.09% followed by Trichophyton tonsurans with 17.91% In conclusion tinea capitis occupies a preponderant place that deserves to be studied, being necessary the detection and early treatments to avoid complications.A case of tinea capitis is presented, where there is clinically evidence of fungal infection by Microsporumcanis.

Liquen Plano Pigmentado:a propósito de un caso / Flat LichenPigmented:Clinical case

RESUMEN El Liquen Plano Pigmentado es una dermatosis crónica frecuente de etiología aún desconocida, caracterizada clínicamente por la presencia de pápulas purpúreas, poligonales, pruriginosasdistribuidas en forma simétrica. ElLiquen Plano Pigmentado representa una de todas las variantes clínicas, cuya característica histológica distintiva es la incontinencia de pigmento melánico. Su curso es autolimitado pues se resuelve en un período de meses a años, pero puede persistir indefinidamente. Existen múltiples opciones de tratamiento, que incluyen corticoides tópicos, intralesionales y sistémicos, retinoides, fototerapia, inmunomoduladores tópicos y, en casos graves o resistentes al tratamiento, la ciclosporina, metotrexato. La dermatoscopía es una técnica auxiliar de diagnóstico no invasivaque permite incrementar la certeza diagnóstica en diversasenfermedades cutáneas; en el caso del Liquen Plano Pigmentado se observa la lesión clásica que consiste en una pápula poligonal aplanada, de tonalidad eritemato-violácea que suele tener finas escamas adherentes en la superficie,denominadasestrías de Wickham, queconsisten en estructuras polimórficas blanquecinas y que corresponden histológicamente a zonas de ortoqueratosis.Es una herramienta de gran utilidad para el diagnóstico de estas lesiones.

ABSTRACT The Pigmented Flat Lichen is a frequent chronic dermatosis of etiology still unknown, clinically characterized by the presence of purpuric, polygonal, pruritic papules distributed symmetrically. The Pigmented Flat Lichen represents one of all clinical variants, where the distinctive histological feature is melanin pigment incontinence. Its course is self-limited, it resolves over a period of months to years, but it can persist indefinitely. There are multiple treatment options that include topical, intralesional and systemic corticosteroids, retinoids, phototherapy, topical immunomodulators and in severe or resistant cases to treatment, cyclosporine, methotrexate. Dermatoscopy is a non-invasive diagnostic auxiliary technique that allows accelerating diagnostic certainty in various skin diseases; in the case of the Pigmented Flat Lichen, the classic lesion is observed, consisting of a flattened polygonal papule, with an erythematous-violet hue that usually has fine adherent scales on the surface, called Wickham striae, which consists of whitish polymorphic structures and that corresponds histologically to areas of orthokeratosis. It is a very useful tool for the diagnosis of these lesions.

Development and content validation of measures assessing adherence barriers and behaviors for use in clinical care.

BACKGROUND: Providers are often unaware of poor adherence to prescribed medications for their patients with chronic diseases. OBJECTIVE: To develop brief, computer-administered patient-reported measures in English and Spanish assessing adherence behaviors and barriers. Design, Participants, and Main Measures: Item pools were constructed from existing measures of medication adherence behaviors and barriers, which informed development of a patient concept elicitation interview guide to identify medication adherence behavior and barrier-related concepts. Two hundred six patients either living with HIV (PLWH) or without were interviewed. Interviews were coded, concepts matched to item pool content, and new items were developed for novel concepts. A provider/investigator team highlighted clinically relevant items. Cognitive interviews were conducted with patients on final candidate items (n = 37). The instruments were administered to 2081 PLWH. KEY RESULTS: Behavioral themes from concept elicitation interviews included routines incorporating time of day, placement, visual cues, and intentionality to miss or skip doses. Barrier themes included health-related (e.g. depressed mood, feeling ill), attitudes/beliefs (e.g., need for medication), access (e.g., cost/insurance problems), and circumstantial barriers (e.g., lack of privacy, disruption of daily routine). The final instruments included 6 behavior items, and 1 barrier item with up to 23 response options. PLWH endorsed a mean (SD) of 3.5 (1.1) behaviors. The 201 PLWH who missed ≥2 doses in the previous week endorsed a mean (SD) of 3.1 (2.5) barriers. The intraclass correlation coefficient (ICC) for the numbers of behaviors endorsed in 61 PLWH after 4-16 days was 0.54 and for the number of barriers for the 20 PLWH with ≥2 missed doses the ICC was 0.89, representing fair and excellent test-retest reliability. CONCLUSION: Measures of medication adherence behaviors and barriers were developed for use with patients living with chronic diseases focusing on clinical relevance, brevity, and content validity for use in clinical care.

Circumstances Surrounding High-risk Sexual Experiences Among Primary Care Patients Living With and Without HIV.

INTRODUCTION: Rates of sexually transmitted infection (STI) are rising in the USA, yet STI risk remains under-addressed by providers, even in HIV care, and with high-risk patients. We interviewed primary care patients living with and without HIV regarding circumstances surrounding sexual risk behavior to identify opportunities for providers to address and reduce STI risk. METHODS: We conducted semi-structured 1:1 interviews with patients living with and without HIV reporting ≥ 1 sex partner and varying STI exposure risk in the past 12 months from four geographically diverse US HIV and primary care clinics. We audio-recorded, transcribed, and coded interviews by circumstance type, using double-coding to ensure inter-coder reliability. We used Fisher's exact and T tests to determine associations with demographic/risk factors. RESULTS: Patients (n = 91) identified a mean of 3 of 11 circumstances. These included substance use (54%), desire for physical/emotional intimacy (48%), lack of HIV/STI status disclosure (44%), psychological drivers (i.e., coping, depression; 38%), personal dislike of condoms (22%), partner condom dislike/refusal (19%), receiving payment for sex (13%), and condom unavailability (9%). Higher proportions of those who were high STI-exposure risk patients, defined as those with ≥ 2 sex partners in the past 3 months reporting never or sometimes using condoms, reported disliking condoms (p = .006); higher proportions of the high-risk and moderate-risk (≥ 2 partners and condom use "most of the time") groups reported substance use as a circumstance (p = .04). CONCLUSION: Circumstances surrounding perceived STI exposure risk were diverse, often overlapping, and dependent on internal, environmental, and partner-related factors and inadequate communication. Meaningful care-based interventions regarding HIV/STI transmission behavior must address the diversity and interplay of these factors.

Medication understanding among patients living with multiple chronic conditions: Implications for patient-reported measures of adherence.

BACKGROUND: Low health literacy is associated with poor medication adherence and poor health outcomes. Limited understanding of prescribed medications may decrease validity of patient-reported adherence measures. OBJECTIVES: To assess knowledge of names and purposes of prescribed medications among patients with multiple chronic conditions. METHODS: Individual interviews were conducted with a convenience sample of patients from six U.S. primary care clinics. Participants (n = 57) were English and/or Spanish-speaking patients prescribed 3+ medications for chronic conditions, for which non-adherence may lead to disability or death. In individual interviews, patients were asked to name their medications, explain the purpose of each, and to explain how they distinguish them from one another. Interviews were audio recorded, transcribed, and coded; coded content was quantified by 1) whether or not the patient could name medications; 2) method of categorizing medications; 3) whether or not the purpose of the medication was understood. Descriptive statistics were compiled using Fisher's exact test to determine the relationship between patient knowledge and medication characteristics. RESULTS: Thirty percent of patients could not name at least one of their medications; 19% did not know their purpose; 30% held misconceptions about the purpose of one or more medications. There was no significant difference in ability to name medications or state their medication's purpose between patients using medi-sets, pre-packaged rolls, or blister packs, and patients who stored pills in their original containers (p = 0.56 and p = 0.73, respectively), or across demographic groups (p = 0.085 to 0.767). CONCLUSIONS: Many patients demonstrated difficulty identifying the name and purpose of prescribed medications; this did not differ by demographic group or medication storage type. Patients may benefit from routine review of medications with their provider in order to improve health literacy, outcomes, and patient-reported adherence measurement.

Encapsidated ultrasmall nanolipospheres as novel nanocarriers for highly hydrophobic anticancer drugs.

The design and construction of novel nanocarriers that have controlled shape and size and are made of inherently biocompatible components represents a milestone in the field of nanomedicine. Here, we show the tailoring of nanoliposphere-like particles for use as biocompatible drug nanocarriers. They are made with the building block components present in human lipoproteins by means of microfluidization, which allows for good size and polydispersity control, mimicking the physical properties of natural low-density lipoproteins (LDLs). This new type of nanocarrier has a negative surface charge and a hydrophobic core that allow the stabilization and encapsulation of hydrophobic anticancer drugs such as camptothecin, resulting in anticancer drug-loaded nanolipospheres. However, we found that the nanoparticles are unstable since their size increases with time. These nanolipospheres were further encapsidated using the non-cytotoxic capsid protein of the plant virus CCMV, which renders the nanoparticles stable. In a more general application, this new virus-like particle confers a controlled microenvironment for the transport of any kind of hydrophobic drug that can bypass the cellular defense mechanisms and deliver its payload.

Validity assessment of the PROMIS fatigue domain among people living with HIV.

PURPOSE: To evaluate psychometric characteristics and cross-sectional and longitudinal validity of the 7-item PROMIS® Fatigue Short Form and additional fatigue items among people living with HIV (PLWH) in a nationally distributed network of clinics collecting patient reported data at the time of routine clinical care. METHODS: Cross-sectional and longitudinal fatigue data were collected from September 2012 through April 2013 across clinics participating in the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS). We analyzed data regarding psychometric characteristics including simulated computerized adaptive testing and differential item functioning, and regarding associations with clinical characteristics. RESULTS: We analyzed data from 1597 PLWH. Fatigue was common in this cohort. Scores from the PROMIS® Fatigue Short Form and from the item bank had acceptable psychometric characteristics and strong evidence for validity, but neither performed better than shorter instruments already integrated in CNICS. CONCLUSIONS: The PROMIS® Fatigue Item Bank is a valid approach to measuring fatigue in clinical care settings among PLWH, but in our analyses did not perform better than instruments associated with less respondent burden.

Use of Cognitive Interviews to Adapt PROMIS Measurement Items for Spanish Speakers Living with HIV.

Purpose. To use cognitive interviewing techniques to assess comprehension of existing Patient-Reported Outcomes Measurement Information System (PROMIS) items among Latinos living with HIV and then refine items based on participant feedback. Methods. Latino monolingual Spanish speakers living with HIV (n = 56) participated in cognitive interviews. Items from four PROMIS domains, including depression, anxiety, fatigue, and alcohol use, were assessed for comprehension. Audiotaped interviews and handwritten notes were subjected to content analysis to identify problems specific to each instrument for each domain. Results. The assessments from the cognitive interviews identified areas for improvement in each domain. We present data on the type of items that were difficult to comprehend and provide examples for how items were refined based on participants' and PROMIS Statistical Coordinating Center (PSCC) feedback. Six out of 48 depression items, 7 out of the 61 anxiety items, 18 out of 42 fatigue items, and 7 out of 44 alcohol use items were found to have poor comprehension. These items were refined based on participant feedback; the items were then submitted to the PSCC for additional guidance on linguistics and grammar to improve comprehension. Conclusions. Cognitive interviews may be used to enhance comprehension of PROMIS items among Latinos.

Análisis DAFO de la Medicina basada en pruebas y nuevas tribus urbanas / SWOT analysis of evidence-based medicine and new urban tribes

Se ha ido configurando un cuerpo de críticas y contraargumentos frente a la medicina basada en pruebas (mal llamada medicina basada en la «evidencia» - MBE - en español), tanto en sus aspectos teóricos como en su aplicación práctica. Con este panorama, desde el Grupo de Trabajo de Pediatría Basada en la Evidencia nos ha parecido un buen momento para reflexionar sobre lo que es y no es la MBE y la metodología DAFO es una herramienta muy útil para ordenar el análisis interno (debilidades y fortalezas) y externo (amenazas y oportunidades) de este ya no tan nuevo paradigma. Porque la MBE es buena si se utiliza de forma correcta, no si se realiza un mal uso y/o abuso, es positiva si se utiliza con raciocinio, no si se usa sin espíritu crítico. Si en la MBE solo se piensa en sus fortalezas y oportunidades y no se balancea con sus debilidades y amenazas, corremos el riesgo de que aparezcan nuevas tribus urbanas alrededor de la MBE. Son cuatro las potenciales nuevas tribus urbanas que hemos ido definiendo, como una forma de avisar de algo que es una realidad no deseada: Cochranitas, Metanófilos, Casperos y Uptodateros. Curiosamente, la posibilidad de que broten estas tribus es inversamente proporcional al trabajo respetuoso en la MBE, de forma que la crítica constructiva se enfoca hacia aquéllos que no respetan la rigurosidad de la forma de trabajo en este paradigma científico. La MBE tiene sus luces y sus sombras, y es obligación de los que creemos en ello favorecer las (muchas) luces y criticar las (pocas, pero dañinas) sombras. Y este artículo pretende hacer de la MBE un lugar mejor y con un objetivo claro: ser mejores sanitarios para ofrecer una mejor atención a nuestros pacientes (AU)

A body of criticism and counterarguments against evidence-based medicine (EBM) has been forming, both about theoretical aspects and practical application. Given this scenario, from the Working Group of Evidence-Based Pediatrics’ point of view, it seems it is a good moment to think about what is and is not the EBM, and a SWOT methodology is a useful tool for organizing the internal (weaknesses and strengths) and external analysis (opportunities and threats) of this not so new paradigm. Because EMB is good if used correctly, and it is not if it’s misused and/or an overuse is made; it is positive when used with reasoning and it is not if used uncritically. Regarding MBE, if we only think about its strengths and opportunities and don’t balance them with its weaknesses and threats, we run the risk that new urban tribes appear around it. There are four potential new urban tribes that we have defined as a way of warning about something that is an unwanted reality: Cochranites, Meta-anophiles, Casperers and Uptodaterers. Interestingly, the likelihood of these tribes to arise is inversely related to the respectful use of EBM, so constructive criticism is focused on those who do not respect the thoroughness of the systematic of working of this scientific paradigm. EBM has its lights and shadows, and it is the duty of those who believe in it to favor the (many) lights and criticize the (few but harmful) shadows. And the aim of this article is to make EBM a better place and with a clear goal: to be better health-providers to provide better health care to our patients (AU)

En lactantes, ¿es más útil la ecografía universal que la selectiva para detectar la displasia del desarrollo de la cadera? / In infants, is the universal ultrasound screening more useful than the selective one to detect the developmental dysplasia of the hip?

Conclusiones de los autores de los estudios: ninguna estrategia ecográfica demuestra mejorar los resultados, incluido el diagnóstico tardío de la displasia del desarrollo de la cadera y la cirugía, pero los estudios tienen poco poder estadístico para detectar diferencias significativas en estos eventos tan poco frecuentes. Comentario de los revisores: por lo infrecuente de la displasia del desarrollo de la cadera y sus consecuencias (necesidad de cirugía, necrosis avascular de la cabeza del fémur, osteoartritis...), no existen estudios de suficiente tamaño y calidad metodológica para responder la pregunta. Algunos estudios recientes de baja calidad metodológica informan del beneficio del cribado universal para disminuir la necesidad de cirugía, sin descartar que con esto aumente la necesidad de tratamientos muchas veces innecesarios (más del 90% de las displasias leves se resuelven espontáneamente entre las seis semanas y los seis meses de edad) y no exentos de complicaciones (AU)

Authors’ conclusion: none of the ultrasound strategies have shown to improve clinical outcomes, including late diagnosis of developmental dysplasia of the hip and surgery, as the studies are substantially underpowered to detect significant differences in these uncommon events. Reviewers’ commentary: due to the low incidence of developmental dysplasia of the hip and its consequences (surgery, avascular necrosis of the femoral head, osteoarthritis ...), currently there are not studies with sufficient size and methodological quality to answer the question. Recent studies of low methodological quality report the benefit of universal screening to reduce the need for surgery, but do not rule out the possibility that this measure could increase the need for treatments that in many cases are unnecessary (mild dysplasia resolves spontaneously between 6 weeks and 6 months in >90% of untreated hips) and not without complications (AU)

Conocimiento y actuación de los padres sobre la fiebre / Knowledge and management of fever by parents

Objetivos: evaluar los conocimientos y actitudes que tienen los padres sobre la fiebre, así como la influencia de los aspectos familiares. Material y métodos: cuestionario distribuido a padres de dos áreas asistenciales con hijos de 1-5 años. Para variables cualitativas se aplicaron pruebas de asociación mediante el test X2; para las variables cuantitativas se aplicó la diferencia de medias mediante la t de Student o análisis de la varianza (ANOVA). Se consideró como valor estadísticamente significativo p < 0,05. Resultados: se analizaron 288 cuestionarios. El 50% de los encuestados tiene dos hijos. Trabaja el 64,5%. En el área urbana son de mayor edad y nivel de estudios (p < 0,001). Un 50,3% considera la fiebre mala, menos los de edad media superior (p < 0,05). El 67,7% utiliza termómetro electrónico. Consideran fiebre una temperatura de 37,7 ºC en axila. Ante la fiebre, el 58,3% utiliza en primer lugar un antitérmico. El 98,2% usa medidas físicas y el 49,3% de ellos piensa que mejoran la fiebre; las usan menos los que trabajan (p < 0,05). Los de estudios superiores quitan ropa y dan líquidos más que los de estudios primarios (p = 0,035). Los antitérmicos más empleados fueron paracetamol e ibuprofeno. Un 64,6% de los encuestados percibe diferencias en cuanto a eficacia. El 85,4% utiliza la dosis indicada por su pediatra y el 21,5%, la que indica la ficha técnica, sobre todo los de estudios superiores frente a los de estudios primarios (p < 0,05). El 67,4% alterna antitérmicos, siempre aconsejados por el pediatra. Conclusiones: globalmente, en la población estudiada existe un buen conocimiento y una actitud adecuada ante la fiebre (AU)

Objective: To assess parental knowledge and attitudes about fever and the influence of social and family aspects. Methods: Questionnaires distributed to parents of children 1-5 years old in two health districts. For qualitative variables association tests with X2 test were applied, and mean differences by Student’s t-distribution or analysis of variance (ANOVA) were used for quantitative variables. It was considered statistically significant the value of p < 0.05. Results: There were 288 questionnaires analyzed. Fifty percent of respondents have 2 children, and 64.5% work. Older age and higher education levels were found in urban areas (p < 0.001). Fever was considered to be a bad thing by 50.3%, less so those with higher mean age (p < 0.05). Electronic thermometers was used in 67.7%, and 86.2% took armpit temperature considering 37.7 ºC as fever. When faced with fever, 58.3% of parents first use antipyretics. Physical measures are used in the first term by 98.2% and 49.3% think these measures lower the fever; they are used less by those parents who work (p < 0.05). Parents with higher education levels remove the clothing and give liquids more than those with primary education (p = 0.035). Most commonly used antipyretics are acetaminophen and ibuprofen; 64.6% perceived differences in efficiency; 65.4% think that ibuprofen is more effective than acetaminophen. Most parents use the dosage prescribed by the pediatrician (85.4%), and 21.5% use the dosage specified in the leaflet, especially those with higher education levels, compared to parents with primary education (p < 0.05). They sometimes alternate antipyretics (67.4%), always following the advice of their pediatrician. Conclusions: There is an overall good knowledge and attitudes about fever (AU)

Prevalence of dental enamel defects in celiac patients with deciduous dentition: a pilot study.

OBJECTIVE: To describe the prevalence of unspecific and systematic enamel defects in children with deciduous dentition diagnosed with celiac disease compared with a control group. STUDY DESIGN: Thirty children (mean age 3.6 yrs) diagnosed with celiac disease and a reference group (n = 30; mean age 3.8 yrs) were studied to determine the prevalence of enamel defects. Both groups had complete deciduous dentition. Unspecific and systematic enamel defects were evaluated according to Aine criteria. RESULTS: Enamel defects were detected in 83.3% of the celiac children versus 53.3% of the control children (P = .025). The corresponding figures for symmetric defects were 73.3% and 23.3% (P < .001), respectively. The most frequent defect severity classification was Aine grade 1. Dental enamel defects were most frequently detected in deciduous molars (45.1%), followed by deciduous incisors. CONCLUSIONS: This study showed significantly more systematic enamel defects in children with celiac disease and deciduous dentition compared with a control group in the same stage of dentition. Dental examination of these defects may be useful to alert for this disease.
