Síndrome visual informático en universitarios en tiempos de pandemia / Computer visual syndrome in university students in times of pandemic

Introducción Una de las consecuencias del uso prolongado de pantallas luminosas como las del ordenador o las del teléfono móvil es el síndrome visual informático (SVI), donde se presentan síntomas característicos que normalmente desaparecen después de un par de horas de haber dejado de usar los aparatos electrónicos. La prevalencia es alta debido a múltiples factores de riesgo. Objetivo Determinar la prevalencia de SVI en estudiantes de Medicina en tiempos de pandemia. Metodología Estudio observacional descriptivo y de corte transversal. La población a estudio fueron estudiantes de Medicina de la Universidad de Boyacá y los datos fueron recogidos en septiembre y octubre del año 2021 a través de una encuesta electrónica. Resultados Un total de 300 personas participaron en el estudio. El 78% (234) de los estudiantes participantes presentan SVI. El 67,09% (157) de los participantes que refirieron presentar SVI pertenecían al sexo femenino y el 32,91% (77) eran del sexo masculino. Conclusiones El SVI es muy común entre los estudiantes de Medicina de la Universidad de Boyacá. Este estudio ha demostrado que la presencia del SVI se ha asociado significativamente a factores exposicionales que se desencadenaron durante el período de pandemia, en donde las clases virtuales frecuentes y durante horarios prolongados conllevaban a una alta exposición a pantallas. Además, en la era de virtualidad la comunicación mediante redes sociales aumentó el uso de teléfonos móviles, lo cual aumenta la posibilidad de aparición de este síndrome. (AU)

Introduction One of the consequences of prolonged use of bright screens such as those of the computer or cell phone is the computer visual syndrome (CVS), where characteristic symptoms are presented that normally disappear after a couple of hours when you stop using electronic devices. The prevalence is high due to multiple risk factors. Objective To determine the prevalence of CVS in medical students at the University of Boyacá in times of pandemic. Methodology Descriptive and cross-sectional observational study. The study population were medical students, the data were collected in September and October of the year 2021, and an electronic survey was carried out for data collection. Results A total of 300 participants were invited to participate in the study. A percentage of 78 (234) of participating students suffer from CVS. A percentage of 67.09 (157) of the participants who reported suffering from CVS were female and 32.91% (77) were male. ConclusionsCVS is very common among medical students at the University of Boyacá. This study has shown that the presence of CVS has been significantly associated with exposure factors that were triggered during the pandemic period, where frequent virtual classes and long hours led to high exposure to screens.

Testing an Adapted Auditory Verbal Learning Test Paradigm for fMRI to Lateralize Verbal Memory in Patients with Epilepsy.

BACKGROUND AND PURPOSE: fMRI is a noninvasive tool for predicting postsurgical deficits in candidates with pharmacoresistant temporal lobe epilepsy. We aimed to test an adapted paradigm of the Rey Auditory Verbal Learning Test to evaluate differences in memory laterality indexes between patients and healthy controls and its association with neuropsychological scores. MATERIALS AND METHODS: We performed a prospective study of 50 patients with temporal lobe epilepsy and 22 healthy controls. Participants underwent a block design language and memory fMRI. Laterality indexes and the hippocampal anterior-posterior index were calculated. Language and memory lateralization was organized into typical and atypical on the basis of laterality indexes. A neuropsychological assessment was performed with a median time from fMRI of 8 months and was compared with fMRI performance. RESULTS: We studied 40 patients with left temporal lobe epilepsy and 10 with right temporal lobe epilepsy. Typical language occurred in 65.3% of patients and 90.9% of healthy controls (P = .04). The memory fMRI laterality index was obtained in all healthy controls and 92% of patients. The verbal memory laterality index was bilateral (24.3%) more frequently than the language laterality index (7.69%) in patients with left temporal lobe epilepsy. Atypical verbal memory was greater in patients with left temporal lobe epilepsy (56.8%) than in healthy controls (36.4%), and the proportion of bilateral laterality indexes (53.3%) was larger than right laterality indexes (46.7%). Atypical verbal memory might be associated with higher cognitive scores in patients. No relevant differences were seen in the hippocampal anterior-posterior index according to memory impairment. CONCLUSIONS: The adapted Rey Auditory Verbal Learning Test paradigm fMRI might support verbal memory lateralization. Temporal lobe epilepsy laterality influences hippocampal memory laterality indexes. Left temporal lobe epilepsy has shown a higher proportion of atypical verbal memory compared with language, potentially to memory functional reorganization.

Utilidad del dispositivo de potenciación del esfínter esofágico distal (LINX®) para pacientes con reflujo gastroesofágico / Usefulness of the distal esophageal sphincter enhancement device (LINX®) for patients with gastroesophageal reflux

Resumen La fundoplicatura de Nissen laparoscópica (FNL) es el gold standard del tratamiento quirúrgico de pacientes con reflujo gastroesofágico patológico (RGE), con perfil de seguridad y resultados a largo plazo satisfactorios en un 80%. En la última década, se ha propuesto el uso de un dispositivo de potenciación del esfínter esofágico inferior (MSA) comercializado como LINX® (de Ethicon, Johnson & Johnson), como alternativa a la cirugía antirreflujo. El dispositivo consiste en una cadena expansible de cuentas de titanio con un núcleo magnético diseñadas para aumentar el tono del esfínter esofágico inferior (EEI) y evitar su relajación inadecuada. Los resultados preliminares han sido alentadores, sin embargo, no está exento de complicaciones. Las indicaciones más aceptadas son: RGE con motilidad esofágica normal y sin esofagitis erosiva, hernia hiatal < 3 cm, IMC <35 kg/m2 y pacientes sin cirugías gastroesofágicas previas. Se instala por vía laparoscópica. Los efectos adversos más importantes son: disfagia con necesidad de dilataciones endoscópicas, y, retiro del dispositivo, entre 1% y 7% a los 2,5 años. La mayoría de los estudios tienen limitaciones metodológicas, conflictos de interés, falta de resultados objetivos y seguimientos a largo plazo, impidiendo llegar a conclusiones extrapolables respecto a la eficacia del MSA.

Laparoscopic Nissen Fundoplication (LNF) is the gold standard of surgical treatment for patients with Gastroesophageal Reflux Disease (GER), with safety profile and long term results satisfactory in 80%. In the last decade, the use of a Lower Esophageal Sphincter Enhancement Device (LESD), marketed as LINX® (from Ethicon, Johnson & Johnson), has been proposed as an alternative to Anti-Reflux Surgery. The device consists of an expandable chain of titanium beads with a magnetic core designed to increase the tone of the lower esophageal sphincter (LES) and prevent its improper relaxation. Preliminary results have been encouraging; however, it is not without complications. The most accepted indications are: GER with normal esophageal motility and without erosive esophagitis, hiatal hernia < 3 cm, BMI <35 kg/m2, and patients without previous gastroesophageal surgeries. It is installed by laparoscopy. The most important adverse effects are: dysphagia with the need for endoscopic dilations, and, removal of the device, between 1 and 7% at 2.5 years. Most of the studies have methodological limitations, conflicts of interest, lack of objective results and long-term follow-up, preventing the reaching of extrapolable conclusions regarding the efficacy of MSA.

Standardization and Chemical Characterization of Intravenous Therapy in Adult Patients: A Step Further in Medication Safety.

BACKGROUND: Intravenous drug administration is associated with potential complications, such as phlebitis. The physiochemical characteristics of the infusate play a very important role in some of these problems. AIM: The aim of this study was to standardize the dilutions of intravenous drugs most commonly used in hospitalized adult patients and to characterize their pH, osmolarity and cytotoxic nature to better guide the selection of the most appropriate vascular access. METHODS: The project was conducted in three phases: (i) standardization of intravenous therapy, which was conducted using a modified double-round Delphi method; (ii) characterization of the dilutions agreed on in the previous phase by means of determining the osmolarity and pH of each of the agreed concentrations, and recording the vesicant nature based on the information in literature; and (iii) algorithm proposal for selecting the most appropriate vascular access, taking into account the information gathered in the previous phases. RESULTS: In total, 112 drugs were standardized and 307 different admixtures were assessed for pH, osmolarity and vesicant nature. Of these, 123 admixtures (40%), had osmolarity values >600 mOsm/L, pH < 4 or > 9, or were classified as vesicants. In these cases, selection of the most suitable route of infusion and vascular access device is crucial to minimize the risk of phlebitis-type complications. CONCLUSIONS: Increasing safety of intravenous therapy should be a priority in the healthcare settings. Knowing the characteristics of drugs to assess the risk involved in their administration related to their physicochemical nature may be useful to guide decision making regarding the most appropriate vascular access and devices.

Agentes hemostáticos tópicos de uso quirúrgico / Topical hemostatic agents for surgical use

Introducción: La morbilidad, mortalidad y costes tras la cirugía se hallan influenciados en gran medida por la pérdida hemática o hemorragia y las consecuencias derivadas de la misma. Para controlar la hemorragia, es frecuente el uso de agentes hemostáticos tópicos en combinación o en adyuvancia a otras técnicas hemostáticas, cuando éstas resultan ineficaces o impracticables. Material y métodos: Se realizó una revisión sistemática en Cochrane y MEDLINE desde el año 2000 a 2017 para identificar las publicaciones relacionadas con el uso de hemostáticos pasivos, activos y sellantes en comparación con otros agentes hemostáticos en todos los tipos de intervenciones quirúrgicas. Resultados: Se seleccionaron 20 ensayos clínicos. La variable principal de eficacia en el 95% fue el tiempo hasta la hemostasia y en el 5% la disminución del sangrado. Las intervenciones quirúrgicas más frecuentes fueron; cirugía hepática (30%), vascular (20%), cardíaca (10%), espinal (10%), general (5%), plástica (5%), y otros tipos de cirugía (20%).Los estudios se dividieron en 7 grupos, en función del tipo de agente hemostático a estudio y el comparador: a) hemostáticos mixtos versus pasivos (10%), b) sellantes de fibrina versus hemostáticos activos (5%), c) sellantes de fibrina versus hemostáticos pasivos (50%), d) hemostáticos mixtos entre sí (15%), e) sellantes de fibrina entre sí (5%), f) hemostáticos pasivos entre sí (5%), g) hemostáticos activos entre sí (10%).Conclusiones: Los hemostáticos activos, mixtos y sellantes de fibrina demuestran superioridad frente a los pasivos en términos de eficacia clínica, con un coste superior y un perfil de efectos adversos similar.

Sepsis en Cirugía / Sepsis in Surgery

Resumen La sepsis constituye una causa frecuente de muerte por lo que es muy importante el diagnóstico precoz para conseguir un manejo oportuno y eficiente. Las definiciones y consensos han ido sufriendo modificaciones a lo largo del tiempo por lo que el equipo médico quirúrgico debe estar atento a estos cambios y debe mantenerse en constante actualización. El consenso de Sepsis-3, propone el uso del qSOFA y SOFA con el fin de mejorar la especificidad del reconocimiento de pacientes de mayor gravedad; no obstante, esto se logra a expensas de una menor sensibilidad, es por esto que los criterios clásicos de SIRS deben seguir utilizándose ante la sospecha de sepsis. Es clave la identificación temprana de los pacientes para que el resultado de las medidas a tomar sea el óptimo. La sepsis quirúrgica sigue siendo un cuadro clínico difícil de reconocer y manejar, es una urgencia que requiere medidas iniciales durante la primera hora de sospecha por lo que es transcendental para el cirujano conocer estas medidas, para poder planificar una posible cirugía de urgencia con el respaldo médico adecuado, según corresponda. El objetivo de esta revisión es que el cirujano y el equipo médico actualicen los cambios de los consensos de sepsis en cuanto al diagnóstico y al manejo bajo una mirada crítica y conozcan también el enfrentamiento adecuado de una sepsis quirúrgica para, de esta manera, mejorar la sobrevida de nuestros pacientes.

Sepsis constitutes a frequent cause of death, early diagnosis is essential to achieve proper management. Definitions and consensus have undergone modifications over time, so the surgical and medical team must be aware of these changes and must be constantly updated. The consensus of Sepsis-3 proposes the use of qSOFA and SOFA in order to improve the specificity of the recognition of patients with greater severity; however, this is achieved at the expense of lower sensitivity, so that the standard SIRS criteria should continue to be used when sepsis is suspected.The early identification of patients is very important to optimize the handling of the medical team. Surgical sepsis remains a difficult clinical picture to recognize and manage. It is an emergency that requires initial actions during the first hour of suspicion. By this it is important for the surgeon to know these actions that allow him or her to plan a possible emergency surgery when appropriate with adequate medical support. The objective of this update is for surgeon and medical team to know the changes in sepsis consensus regarding diagnosis and management under a critical view, as well as to know the therapeutic approach of a surgical sepsis to improve the survival of our patients.

Mascarillas: producto imprescindible en la pandemia COVID-19 / Masks: essential product in the pandemic COVID-19

Las mascarillas son un elemento básico de protección y limitación de la propagación de la infección por coronavirus. En concreto y en la situación de pandemia sanitaria mundial ante la que nos encontramos frente al COVID-19. Podemos diferenciar varios tipos de mascarillas (quirúrgicas, autofiltrantes, higiénicas, etc.), teniendo cada una de ellas una consideración diferente en cuanto a tipo de producto, requisitos normativos y protección que nos ofrecen. La situación de pandemia actual en la que nos encontramos, hace imprescindible el uso de las mismas para limitar la propagación de agentes infecciosos

Masks are a basic element of protection and limitation of the spread of coronavirus infection. We can distinguish several types of masks (surgical, auto filtering, hygienical, etc.), which have different considerations related to the type of product, regulatory requirements, and grade of protection. The current pandemic situation makes essential the use of masks to limit the spread of infectious agents

Light-Induced Tetrazole-Quinone 1,3-Dipolar Cycloadditions.

Quinones were firstly used as dipolarophiles in a photoclick 1,3-cycloaddition with 2,5-diaryltetrazoles, as photoactivatable predipoles, providing a novel and efficient access to three types of pyrazole-fused quinones (indazoledione derivatives). Distinctive features of this protocol include the use of light as the unique reagent and readily available, stable, and easy to handle starting materials and good to excellent yields. Photophysical and electrochemical properties of the quinones and their potential application as photoredox catalysts are also detailed.

Asymmetric Synthesis and Chiroptical Properties of Enantiopure Helical Ferrocenes.

An enantiopure helical ferrocene ( Rp)-5 with five ortho-condensed aromatic rings was synthesized using a PtCl2-catalyzed cycloisomerization of planar-chiral 2-ethynyl-1-(4-phenanthrenyl)ferrocene ( Rp)-6f, prepared in 3 steps from known enantiopure sulfinyl ferrocenyl boronic acid ( SS, Sp)-7, as the source of planar chirality. This pentacyclic helical ferrocene showed a very high optical rotation value and strong circular dichroism (CD) signals.

Angular tetracyclic p-peroxyquinols, p-quinols, and a pentacyclic double peroxide, showing anticancer properties, were synthesized from the corresponding phenols by an environmentally friendly solvent- and wavelength-controlled irradiation under air in the absence of an external photosensitizer.

Revisión de la evidencia sobre el manejo de medicamentos y productos peligrosos en los servicios de Urología. Documento de consenso entre la Asociación Española de Urología y la Sociedad Española de Farmacia Hospitalaria / Review of the evidence on handling drugs and hazardous products in Urology Departments. Consensus document between the Spanish Urological Association and the Spanish Society of Hospital Pharmacy

Introducción: La administración intravesical de medicamentos peligrosos es una práctica habitual en el ámbito de la urología, con posible exposición del personal sanitario a dichos medicamentos. Se considera necesario disponer de un documento de consenso entre las sociedades científicas implicadas -Asociación Española de Urología y Sociedad Española de Farmacia Hospitalaria- que recoja la mejor evidencia disponible para el manejo, de la forma más segura posible, de medicamentos peligrosos en el ámbito de los servicios de Urología. Métodos: Se ha realizado una revisión de la legislación y de las recomendaciones sobre el manejo de medicamentos peligrosos tanto a nivel estatal como internacional. Resultados: Se dispone de legislación nacional y de normativas para la protección de los trabajadores que manipulen medicamentos y productos peligrosos, así como recomendaciones de manipulación para la protección tanto del producto, como de los trabajadores. Discusión: Siguiendo las líneas estratégicas del Parlamento Europeo para el período 2014-2020 en el capítulo de seguridad y salud laboral, la Asociación Española de Urología y la Sociedad Española de Farmacia Hospitalaria proponen una serie de actuaciones que hagan disminuir los riesgos de exposición a los profesionales y cuidadores implicados en su manejo. Conclusiones: Tras esta revisión se establecen 19 recomendaciones para el manejo de medicamentos peligrosos que pueden resumirse en la necesidad de formación de todas las personas implicadas (desde equipos directivos hasta los pacientes y cuidadores), adopción de sistemas que no permitan fugas contaminantes, programas de vigilancia de las exposiciones y optimización de los recursos disponibles

Background: The intravesical administration of hazardous drug products is a standard practice in the urology setting, which potentially exposing medical personnel to these drug products. It was deemed necessary to have a consensus document among the scientific societies involved (the Spanish Urological Association and the Spanish Society of Hospital Pharmacy) that collects the best available evidence on the safest handling possible of dangerous drug products in the setting of urology departments. Methods: We reviewed the legislation and recommendations on the handling of dangerous drug products, both at the national and international level. Results: There is national legislation and regulations for protecting workers who handle dangerous drugs and products, as well as recommendations for handling to protect both the product and workers. Discussion: Following the strategic lines of the European Parliament for 2014-2020 in the chapter on occupational safety and health, the Spanish Urological Association and the Spanish Society of Hospital Pharmacy proposed a series of actions that decrease the risks of exposure for practitioners and caregivers involved in the handling of these products. Conclusions: After this review, 19 recommendations were established for handling dangerous drug products, which can be summarised as the need to train all individuals involved (from management teams to patients and caregivers), adopt systems that prevent contaminating leaks, implement exposure surveillance programmes and optimise available resources

Exposure-safety and efficacy response relationships and population pharmacokinetics of eslicarbazepine acetate.

OBJECTIVES: Eslicarbazepine acetate (ESL) is a once-daily (QD) oral antiepileptic drug (AED) for focal-onset seizures (FOS). Pharmacokinetic (PK) and pharmacodynamic (PD) models were developed to assess dose selection, identify significant AED drug interactions, and quantitate relationships between exposure and safety and efficacy outcomes from Phase 3 trials of adjunctive ESL. METHODS: Eslicarbazepine (the primary active metabolite of ESL) population PK was evaluated using data from 1351 subjects enrolled in 14 studies (11 Phase 1 and three Phase 3 studies) after multiple oral doses ranging from 400 to 1200 mg. Population PK and PD models related individual eslicarbazepine exposures to safety outcomes and efficacy responses. RESULTS: Eslicarbazepine PK was described by a one-compartment model with linear absorption and elimination. The probability of a treatment-emergent adverse event (TEAE; dizziness, headache, or somnolence) was higher with an initial dose of ESL 800 mg than with an initial dose of ESL 400 mg QD. Body weight, sex, region, and baseline use of carbamazepine (CBZ) or lamotrigine were also found to influence the probability of TEAEs. Eslicarbazepine exposure influenced serum sodium concentration, standardized seizure frequency, and probability of response; better efficacy outcomes were predicted in patients not from Western Europe (WE; vs WE patients) and those not taking CBZ (vs taking CBZ) at baseline. CONCLUSIONS: Pharmacokinetic and PK/PD modeling were implemented during the development of ESL for adjunctive treatment of FOS in adults. This quantitative approach supported decision-making during the development of ESL, and contributed to dosing recommendations and labeling information related to drug interactions.

Retrospective study of perampanel efficacy and tolerability in myoclonic seizures.

OBJECTIVES: Perampanel is an antiepileptic drug (AED) approved for add-on treatment of focal seizures (with or without generalization) and primary generalized tonic-clonic (GTC) seizures. Our objective was to explore the effectiveness and tolerability of adjunctive perampanel in patients with drug-resistant myoclonic seizures, after failure of other AEDs. MATERIALS AND METHODS: Retrospective, multicenter, observational study. Data were collected from individual patient clinical files and analysed using appropriate descriptive statistics and inferential analyses. RESULTS: Data are reported for 31 patients with mean age 36.4 years, who had an average epilepsy duration of 18 years, previously taken an average of 5.03 AEDs, and were taking an average of 2.4 AEDs on perampanel initiation. Patients exhibited myoclonic, GTC, absence, tonic and focal seizures, and most had associated cognitive decline and/or ataxia. Median time on perampanel was 6 months, most common dose was 6 mg, and overall retention rate was 84%. The responder rate for myoclonic seizures was defined via reduction of days with myoclonic seizures per month. At 6 months, 15 (48.4%) of the 31 patients were classed as myoclonic seizure responders, 10 (32.3%) were myoclonic seizure free, and 39% saw improvements in functional ability. Of 17 patients with GTC seizures at baseline, 9 (53%) were responders at 6 months, and 8 (47.1%) were seizure free. The most frequent side effects were psychiatric disorders, instability, dizziness and irritability, and mostly resolved with dose reduction. Five patients discontinued perampanel due to side effects. CONCLUSIONS: Perampanel caused clinically meaningful improvements in patients with drug-resistant myoclonic seizures. It was generally well tolerated, but psychiatric and neurological side effects sometimes required follow-up and dose reduction.

Musicogenic reflex seizures in epilepsy with glutamic acid decarbocylase antibodies.

BACKGROUND: Musicogenic reflex seizures (MRS) are a rare form of seizures described in patients with temporal lobe epilepsy (TLE), mainly of unknown etiology. Epilepsy with antibodies against glutamic acid decarboxylase (GAD-ab) is a form of autoimmune epilepsy for which no specific semiology has been described. AIM OF THE STUDY: To retrospectively review the incidence of MRS in the general epileptic population and in the series of patients with epilepsy and GAD-ab and to describe its clinical and paraclinical characteristics. METHODS: Patients recorded between January 2010 and January 2016 in the Database of Bellvitge Hospital Epilepsy Unit were reviewed. RESULTS: From a group of 1510 epileptic patients, three reported MRS (0.0019%) (two patients with epilepsy and GAD-ab and one patient with cryptogenic TLE). The incidence of MRS in patients with epilepsy and GAD-ab was 2 of 22 (9%). Both patients had a normal magnetic resonance Imaging (MRI), but FDG-PET showed medial temporal lobe hypometabolism (unilateral or bilateral) in both and also in the insula in one of them. MRS (recorded via video-EEG[electroencephalography] in one patient) arose from the right temporal lobe. CONCLUSIONS: MRS may be a distinctive seizure type in patients with epilepsy and antiGADab. Determination of GAD-ab should be carried out in all cases of MRS, even those with normal structural MRI.

Sulfoxide-Induced Homochiral Folding of ortho-Phenylene Ethynylenes (o-OPEs) by Silver(I) Templating: Structure and Chiroptical Properties.

A new family of homochiral silver complexes based on carbophilic interactions with ortho-phenylene ethynylene (o-OPE) scaffolds containing up to two silver atoms are described. These compounds represent a unique class of complexes with chirality at the metal. Chiral induction is based on the inclusion of chiral sulfoxides, which allow efficient transfer of chirality to the helically folded o-OPE, leading to circularly polarized luminescence (CPL)- and vibrational circular dichroism (VCD)-active compounds. In the presence of silver(I) cations, carbophilic interactions dominate, which promote helical structures with a defined helicity. This is one of the very scarce examples of the use of such interactions in the attractive field of abiotic foldamers. The switching event has been extensively studied by using different chiroptical techniques, including circular dichroism, CPL, and VCD, and represents one of the few CPL switches described in the literature.

Non-traumatic limping in Paediatric Emergencies: Epidemiology, evaluation and results. / Cojera no traumática en Urgencias de Pediatría. Epidemiología, valoración y resultados.

INTRODUCTION: Non-traumatic limping is a common reason for consultation in paediatric emergencies. Although transient synovitis of the hip (TS) is the most frequent diagnosis, there are cases of limping secondary to serious pathologies. The aim of this review is to describe the variables related to non-traumatic limp that come to the paediatric emergency department to establish the best management protocol, making the most of resources and speeding up emergency care. MATERIAL AND METHOD: A prospective study was conducted, selecting all children less than 15 years old who consulted aspaediatric emergencies for non-traumatic limping during the 2014. Clinical variables, complementary examinations and diagnoses were collected in the emergency room consultation and 6 months after the consultation RESULTS: During 2014, 146 patients (0.69% of the emergencies) were included in the non-traumatic limping study. Four cases of severe limping were diagnosed: 2 leukaemias, 1 septic arthritis and 1 acetabular bone tumour. The most frequent diagnosis was TS (53.16%). At 6 months, 135 children (92.4%) had resolved lameness. The diagnosis was changed in 9 children (6.1%). Children with TS had fewer days of evolution, and 77% were between 3 and 10 years old. Children with a final diagnosis of severe pathology had a limp for longer, fever and did not weight bear on ambulation. CONCLUSIONS: In limping of probable hip origin, at the ages of between 3 and 10, without fever or systemic symptoms and of less than one week's onset, it is possible to make a clinical diagnosis of TS limiting the use of complementary examinations.
