RESUMO
ABSTRACT Objective: To evaluate the prevalence of hidden neuraxial pathology (NAP) revealed in idiopathic scoliosis (IS) in neurologically normal patients. Methods: We selected 401 patients with IS who visited our clinic. We identified patterns of NAP and its frequency. In addition to the main part of the study, we assessed the reliability of Magnetic Resonance Imaging (MRI) measuring of the pedicles to plan screw width and trajectory. Results: Among the 401 patients, 53 (13%) presented NAP. The proportion of males in this group was higher (42% vs. 21%, p=0.004), the age of onset of the deformity was lower (8.9±3.77 vs. 9.9±3.93 years old, p=0.045), the left-sided thoracic curve was more frequent (21% vs. 8%, p=0.016), thoracic kyphosis was more pronounced (p=0.070), and the percentage of revision surgeries for deformity progression or non-fusion was higher (13% vs. 5%, p=0.147). Conclusions: The spine MRI should be performed in the early stages of IS, as in some cases of NAP (Chiari, tethered spinal cord), there is the possibility of an early neurosurgical operation that will prevent the development of scoliosis. The main signs of hidden NAP in IS are early-onset IS, IS with left-sided thoracic curve, male gender, and thoracic kyphosis > 40°Cobb. Level of Evidence II; Retrospective Study.
Resumo: Objetivo: Avaliar a prevalência das patologias neuroaxiais ocultas (PNO) reveladas na escoliose idiopática (EI) em pacientes neurologicamente normais. Métodos: Foram selecionados 401 pacientes com EI que visitaram nossa clínica. Identificamos padrões de PNO e sua frequência. Além disso, avaliamos a confiabilidade da medição por ressonância magnética (RM) dos pedículos para planejar a largura e a trajetória do parafuso. Resultados: Entre os 401 pacientes, 53 (13%) apresentaram PNO. A proporção de homens neste grupo foi maior (42% contra 21%, p=0,004), a idade de início da deformidade foi menor (8,9±3,77 contra 9,9±3,93 anos, p=0,045), a curva torácica do lado esquerdo foi mais frequente (21% contra 8%, p=0,016), a cifose torácica foi mais pronunciada (p=0,070) e a porcentagem de cirurgias de revisão para progressão da deformidade ou não fusão foi maior (13% contra 5%, p=0,147). Conclusões: A ressonância magnética da coluna deve ser realizada nos estágios iniciais da EI, pois em alguns casos de PNO (Chiari, medula espinhal amarrada) existe a possibilidade de uma operação neurocirúrgica precoce que impedirá o desenvolvimento de escoliose. Os principais sinais de PNO oculta na EI são: EI de início precoce, EI com curvatura torácica à esquerda, sexo masculino e cifose torácica > 40°Cobb. Nível de Evidência II; Estudo Retrospectivo.
Resumen: Objetivo: Evaluar la prevalencia de las patologías neuroaxiales ocultas (PNO) reveladas en la escoliosis idiopática (EI) en pacientes neurológicamente normales. Métodos: Se seleccionaron 401 pacientes con EI que visitaron nuestra clínica. Se identificaron patrones de PNO y su frecuencia. Además, evaluamos la fiabilidad de la medición por resonancia magnética (RM) de los pedículos para planificar la anchura y la trayectoria del tornillo. Resultados: Entre los 401 pacientes, 53 (13%) presentaron PNO. La proporción de hombres en este grupo fue mayor (42% vs 21%, p=0,004), la edad de aparición de la deformidad fue menor (8,9±3,77 vs 9,9±3,93 años edad, p=0,045), la curva torácica del lado izquierdo se encontró con más frecuencia (21 % frente a 8 %, p=0,016), la cifosis torácica fue más pronunciada (p=0,070) y el porcentaje de cirugías de revisión por progresión de la deformidad o falta de fusión fue mayor (13% vs 5%, p=0,147). Conclusiones: La resonancia magnética de la columna debe realizarse en las primeras etapas de la EI, ya que en algunos casos de PNO (Chiari, médula anclada) existe la posibilidad de una operación neuroquirúrgica temprana que prevendrá el desarrollo de la escoliosis. Los principales signos de PNO oculta en EI son: EI de inicio temprano, EI con curvatura torácica izquierda, sexo masculino y cifosis torácica > 40°Cobb. Nivel de Evidencia II; Estudio Retrospectivo.

Presentamos dos pacientes no relacionados con ataxia cerebelosa de inicio tardío asociada con neuropatía y tos seca de larga data. Un paciente tenía dos hermanos afectados con neuropatía sensorial y tos. Ambos probandos tuvieron investigaciones extensas que incluyó pruebas genéticas negativas para las ataxias más comunes, así como pruebas paraneoplásicas y otras causas inmunológicas. Ambos pacientes mostraron una expansión intrónica anormal en el pentanucleótido AAGGG del gen RFC1. Esta etiología se informa como causa frecuente de ataxia de inicio en adultos; la presencia de tos puede conducir al diagnóstico correcto.
We report two unrelated patients with late-onset cerebellar ataxia associated with neuropathy and a long-standing dry cough. One patient had two siblings affected with sensory neuropathy and cough. Both probands had extensive investigations including genetics testing negative for most common ataxias as well as testing for paraneoplasic and other immunologic causes. Both patients showed an abnormal intronic expansion in the pentanucleotide AAGGG of the gene RFC1. This etiology is being reported as frequent cause of adult-onset ataxia; the presence of cough may lead to the correct diagnosis.

Introducción. Con las nuevas terapias, el diagnóstico temprano de la atrofia muscular espinal (AME) es esencial. El objetivo de este estudio es analizar los distintos componentes que influyen en el retraso diagnóstico. Población y métodos. Se incluyeron pacientes con un diagnóstico molecular de AME tipo I, II y III. Se estudiaron varios parámetros, como la edad al momento de la aparición del primer signo, qué signo fue y el intervalo entre este y el diagnóstico confirmado. Neurólogos especialistas realizaron entrevistas que se complementaron con la revisión de historias clínicas cuando fue necesario. Resultados. Se entrevistaron 112 pacientes. AME I n = 40, AME II n = 48, AME III n = 24. La mediana de edad en meses al momento del reporte del primer signo fue AME I: 1,5 (R 0-7), AME II: 9 (R 2-20), AME III: 18 (R 8-180). Los primeros signos fueron reconocidos por los padres en el 75 % al 85 % de las veces en todos los subtipos. La mediana del tiempo transcurrido entre el primer signo y la primera consulta médica fue menor a un mes en los tres tipos. La mediana de tiempo transcurrido en meses entre el primer signo y el diagnóstico molecular confirmado fue en AME I: 2 (R 0-11), en AME II: 10 (3-46) y en AME III: 31,5 (R 4-288). Conclusiones. Existe un significativo retraso en el diagnóstico de la AME relacionado fundamentalmente a la falta de sospecha clínica. La demora es menor en AME I y mayor en AME III. Otros factores incluyen deficiencias en el sistema de salud.
Introduction. News treatments, make early diagnosis of spinal muscular atrophy (SMA) critical. The objective of this study is to analyze the different factors that influence delay in diagnosis. Population and methods. Patients with a molecular diagnosis of types I, II, and III SMA were included. Several parameters were studied, such as age at onset of first sign, what sign it was, and the time from recognition of first sign to confirmed diagnosis. Neurologists specialized in SMA conducted interviews, supported by the review of medical records when deemed necessary. Results. A total of 112 patients were interviewed. SMA I n = 40, SMA II n = 48, SMA III n = 24. The median age in months at the time of reporting the first sign was SMA I: 1.5 (R: 07), SMA II: 9 (R: 220), SMA III: 18 (R: 8180). In all subtypes, first signs were identified by parents from 75% to 85% of the times. The median time from first sign to first medical consultation was less than a month in all 3 types. The median time in months, from first sign to confirmed molecular diagnosis in SMA I was: 2 (R: 011), in SMA II: 10 (R: 346), in SMA III: 31.5 (R: 4288). Conclusions. There is a significant delay in SMA diagnosis mainly related to the absence of clinical suspicion. The delay is shorter in SMA I and longer in SMA III. Other factors include deficiencies in the health care system.

Background: Smoking is one of the most relevant public health problems worldwide and one of the main causes of preventable premature death. In-hospital treatment and subsequent follow-up are effective in terms of cessation. Aim: To determine the frequency of smoking habits among patients hospitalized at a private clinic in Santiago. Material and Methods: Hospitalized patients were invited to answer a structured and adapted questionnaire on smoking habits. Results: The survey was answered by 294 patients (56% women). Twenty three percent of respondents were smokers. Among smokers, 50% indicated a consumption from 1 to 5 cigarettes per day, 19% smoked during the first hour after waking, and 43% lived with another smoker in their home. Eighty three percent thought about quitting and made unsuccessful attempts to quit using different strategies. Conclusions: The percentage of smokers in this group of patients is lower than that reported in the national health survey. The high proportion of respondent that are attempted to quit and failed, justifies the availability of structured quitting programs at the hospital and follow-up strategies after discharge.

Resumen Introducción: El Síndrome de Turner (ST) es una alteración cromosómica sexual causada por la ausencia parcial o completa del cromosoma X, además de mosaicismos y otras alteraciones estructurales del cromosoma X o Y; está presente en 1 de 2500 nacidas vivas. Objetivo: Describir las variantes citogenéticas de pacientes con síndrome de Turner y evaluar su asociación con el fenotipo de presentación y la edad del diagnóstico. Método: Estudio retrospectivo de corte transversal de una serie de 82 casos de síndrome de Turner. Los cariotipos fueron realizados utilizando el medio RPMI-1640; las preparaciones de cromosomas se obtuvieron utilizando técnicas estándar y se analizaron mediante bandas GTG con una resolución de 400-450 bandas, donde se contó con 20-50 metafases para reducir la probabilidad de no detección de mosaicismo. Resultados: 45 (55.6%) fueron diagnosticadas, con monosomía clásica del cromosoma X, mientras 29 (35,8%) mostraron anomalías estructurales del cromosoma X y 7 (8,6%) se asociaron a mosaicos numéricos del cromosoma X. Solo 21 (26%) pacientes fueron diagnosticadas por debajo de los 12 años, mientras el resto 60 (74%) se detectaron entre la adolescencia y la adultez. La baja estatura fue una característica universal en todos los grupos de estudio. Conclusiones: Las fórmulas cromosómicas en el síndrome de Turner pueden ser muy variadas y tener diversas implicaciones en el fenotipo; se destaca la baja talla como un criterio clínico relevante en la sospecha clínica.
Abstract Introduction: Turner Syndrome (TS) is a sexual chromosomal alteration caused by the partial or complete absence of the X chromosome, in addition to mosaicisms and other structural alterations of the X or Y chromosome; It is present in 1 in 2,500 live births. Objective: To describe the cytogenetic variants of Turner syndrome patients and to evaluate their association with the phenotype at presentation and age at diagnosis. Methods: Retrospective cross-sectional study of a series of 82 cases of Turner syndrome. Karyotypes were performed using RPMI-1640 medium; Chromosome preparations were obtained using standard techniques and analyzed by GTG banding with a resolution of 400-450 bands where 20-50 metaphases were counted to reduce the probability of missing mosaicism. Results: 45 (55.6%) were diagnosed with classic monosomy of the X chromosome, while 29 (35.8%) showed structural abnormalities of the X chromosome and 7 (8.6%) were associated with numerical mosaics of the X chromosome. Only 21 (26%) patients were diagnosed under 12 years of age, while the rest 60 (74%) were detected between adolescence and adulthood. Short stature was a universal characteristic in all study groups. Conclusions: The chromosomal formulas in Turner syndrome can be variable and have different implications in the phenotype; short stature stands out as a relevant clinical criterion in clinical suspicion.

Abstract Background: Spinocerebellar ataxia type 3 (SCA3) is the most common autosomal dominant spinocerebellar ataxia worldwide. Almost all patients with SCA3 exhibit nystagmus and/or saccades impairment. Objective: To investigate the presence of nystagmus as an early neurological manifestation, before ataxia, in some patients with SCA3 in the first six months of the disease. Methods: We evaluated a series of 155 patients with clinically and molecularly proven SCA3 between 2013 and 2020. Data regarding sex, age, age at onset, disease duration, CAG repeat expansion length, first symptom, presence of ataxia, scores on SARA and ICARS scales, and presence and characteristics of nystagmus were collected. Results: We identified seven patients with symptomatic SCA3 who presented with isolated nystagmus. In these seven individuals the age at onset ranged from 24 to 57 years, and disease duration from four to six months. Conclusions: Our study showed that nystagmus may be the first neurological sign in SCA3. This clinical observation reinforces the idea that the neurodegenerative process in SCA3 patients may start in vestibular system connections or in flocculonodular lobe. This study adds relevant information about pre-symptomatic features in SCA3 that may work as basis for a better understanding of brain degeneration and for future therapeutic clinical trials.
RESUMO Antecedentes: A ataxia espinocerebelar tipo 3 (SCA3) é a ataxia espinocerebelar de herança autossômica dominante mais comum em todo o mundo. Quase todos os pacientes com SCA3 têm nistagmo e/ou comprometimento das sácades. Objetivo: Investigar a presença de nistagmo como manifestação neurológica precoce, antes do surgimento da ataxia, em alguns pacientes com SCA3 nos primeiros seis meses de doença. Métodos: Foram avaliados 155 pacientes com diagnóstico clínico e molecular de SCA3, entre 2013 e 2020, em relação a sexo, idade, idade de início, duração da doença, expansão da repetição CAG, primeiro sintoma, presença de ataxia, pontuações nas escalas SARA e ICARS, e presença e caracterização de nistagmo. Resultados: Identificamos sete pacientes com SCA3 que apresentavam nistagmo isolado. A idade de início da doença nesses pacientes variou de 24 a 57 anos e a duração da doença variou de quatro a seis meses. Conclusões: O nosso estudo mostrou que o nistagmo pode ser o primeiro sinal neurológico na SCA3. Essa observação clínica reforça a ideia de que o processo neurodegenerativo nos pacientes com SCA3 pode se iniciar nas conexões do sistema vestibular ou no lobo floculonodular. Este estudo adiciona informações relevantes sobre características pré-sintomáticas na SCA3 e que podem servir de base para melhor entendimento da degeneração cerebral e para futuras terapias.

Objetivos: describir hallazgos de videocapilaroscopía (VCP) en pacientes con fenómeno de Raynaud primario (FRP) y secundario (FRS); comparar características demográficas y clínicas entre ambos. Materiales y métodos: estudio observacional, analítico, transversal. Se documentaron edad, ocupación, tiempo de evolución del FR, enfermedad del tejido conectivo (ETC) y características capilaroscópicas. Las VCP se informaron como patrón normal, inespecífico o SD temprano, activo y tardío. Se realizó estadística descriptiva. Para variables categóricas se empleó Chi² o test exacto de Fisher; para variables continuas, t test o Man Whitney, considerando estadísticamente significativa p<0,05. Resultados: se realizaron 290 VCP. En pacientes con FRP (n:122), 18% (n:23) fue normal y 81% (n:99) con patrón inespecífico. En pacientes con FRS (n:168), 8% fue normal, 42% con patrón inespecífico y 51% con patrón SD (25% temprano, 44% activo, 31% tardío). Se hallaron diferencias estadísticamente significativas: tiempo de evolución de FR en meses (12 vs 36, p<0,01), VCP normal (18,85% vs 7,4%, p<0,01), patrón inespecífico (81,14% vs 41%, p<0,01) en pacientes con FRP vs. FRS. Conclusiones: en pacientes con FRS predominó el patrón SD, mientras que en aquellos con FRP fue superior el patrón normal e inespecífico. El FRS se asoció a mayor tiempo de evolución.
Objectives: to describe videocapillaroscopy (VCP) findings in patients with primary Raynaud's phenomenon (PRP) and secondary (SRP); compare demographic and clinical characteristics between both. Materials and methods: observational, analytical, cross-sectional study. Age, occupation, evolution time of RP, connective tissue disease (CTD) and capillaroscopic characteristics were documented. The VCP were reported as normal, nonspecific or early, active, and late SD pattern. Descriptive statistics were performed. Chi² or Fisher's exact test were used for categorical variables; for continuous variables t test or Man Whitney, considering statistically significant p<0.05. Results: 290 VCP were performed. In patients with PRP (n:122), 18% (n:23) were normal and 81% (n:99) non-specific. In patients with SRP (n:168), 8% were normal, 42% non-specific and 51% with SD pattern (25% early, 44% active, 31% late). We found statistically significant differences: time of evolution of RP in months (12 vs. 36, p<0.01), normal VCP (18.85% vs 7.4%, p<0.01), non-specific pattern (81.14% vs 41%, p<0.01) in patients with PRP vs SRP. Conclusions: in patients with FRS predominated the SD pattern, while in those with FRP the normal and nonspecific pattern was superior. FRS was associated with a longer evolution time.

SUMMARY OBJECTIVE: Our study aimed to explore the potential risk factors for radiological hip joint involvement in patients with ankylosing spondylitis (AS). METHODS: This cross-sectional convey collected the clinical data, laboratory indicators, and radiographic data of patients with AS. Radiographic hip joint involvement was defined as a Bath Ankylosing Spondylitis Radiology Hip Index (BASRI-hip) score ≥2. Multivariate logistic regression analyses were conducted to explore the potential risk factors for radiological hip involvement in patients with AS. RESULTS: Based on BASRI-hip score, all enrolled 386 patients with AS were classified as patients involving with radiological hip joint involvement (BASRI-hip ≥2; n=203) and those without it (BASRI-hip ≤1; n=183). Mean age of enrolled patients with AS were 36.7±11.9 years, and 320 (82.9%) patients were male. Mean course of disease was 10.7±8.3 years, and 349 (90.4%) patients were with a positive HLAB27. Multivariate analyses indicated that Juvenile onset (onset age ≤16 years) (odds ratio [OR]=4.159, 95% confidence interval [CI], 1.779-9.721, p<0.001), body mass index (BMI) <18.5 kg/m2 (OR=1.986, 95%CI 1.187-3.323, p=0.009), continuous nonsteroidal anti-inflammatory drug (NSAID) use (OR=0.351, 95%CI 0.155-0.794, p=0.012), and bone mass below the expected range for age (Z score ≤-2) (OR=2.791, 95%CI 1.456-5.352, p=0.002) were independently associated with radiological hip joint involvement in patients with AS. CONCLUSIONS: The potential risk factors for radiological hip joint involvement were juvenile onset, lower BMI, and bone mass below the expected range for age. Furthermore, continuous NSAID use was the protective factor for radiological hip joint involvement in these population.

Reportamos una serie de tres casos de niños con fibrosis quística (FQ) y diagnóstico de diabetes a muy temprana edad. RESULTADOS. Caso 1: Niño de 8 años, con diagnóstico de fibrosis quística a los 3 meses de vida por test de sudor y estudio genético p.Phe508del /-. Presenta hiperglicemia no cetósica desde los 6 meses de edad, con colonización traqueal de Staphylococcus Aureus (SA) y Pseudomona Aeruginosa (PA) y debut de diabetes a los 2 años 1 mes. Caso 2: Niño de 16 años, a los 7 meses de vida se diagnostica FQ por test de sudor y estudio genético p.Phe508del /-. Presenta colonización traqueal por SA y múltiples infecciones por PA. A los 5 años 7 meses se diagnostica diabetes presentando cetosis al debut. Caso 3: Niño de 13 años, con diagnóstico de FQ a los 7 meses de vida mediante test de sudor y estudio genético p.Phe508del/-. Presenta colonización traqueal por SA y múltiples infecciones por PA, se realiza diagnóstico de diabetes a los 2 años 7 meses de edad. DISCUSIÓN: La diabetes asociada a fibrosis quística es una complicación frecuente en adultos con fibrosis quística, pero puede presentarse desde edades tempranas. Se debe tener alto nivel de sospecha para el diagnóstico oportuno y óptimo manejo.
INTRODUCTION: Diabetes is the most common extra pulmonary complication in adults with cystic fibrosis (CF). There are few reports of diabetes related to (CF) in preschool children worldwide. Prevalence in Chile is unknown. MÉTODO: We report ta serie of three cases of children with CF and diagnosis of diabetes at an early age. Case 1: Boy 8 year old, CF diagnosed at the age of 3 months by sweat test and genetic study p.Phe508del/-. He presented non-ketotic hyperglycemia since he was 6 months old, with tracheal colonization of Staphylococcus Aureus (SA) and Pseudomona Aeruginosa (PA) , and diagnosis of diabetes at the age of 2 years 1 month. Case 2: Boy patient, 16 years old, with diagnosis of CF at the of age 7 months by sweat test and genetic study p.Phe508del/-. He presents tracheal colonization by SA and multiple PA infections. At the age 5 years 7 months, diabetes is diagnosed, presenting ketosis at the beginning. Case 3: Boy 13 years diagnosed with CF at the age of 7 months, presented sweat test and genetic study p.Phe508del/-. He presents tracheal colonization by SA and multiple infections. DISCUSSION: CF related diabetes is common in adults with cystic fibrosis, but it can be diagnosed in early childhood. A high level of suspicious is required for a proper and timely diagnosis

La hemosiderosis pulmonar idiopática (HPI) es una causa de hemorragia alveolar difusa. OBJETIVO: describir la evolución de niños con HPI en nuestra institución. Se realizó una revisión retrospectiva con protocolo de seguimiento. Se reclutaron 13 pacientes, 7 hombres. Procedentes de una zona agrícola (6/13). No todos presentaron la tríada diagnóstica completa: infiltrados algodonosos (9/13), anemia (11/13), hemoptisis (9/13). Todos evidenciaron un recuento de hemosiderófagos sobre 30% en el lavado broncoalveolar. Tomografía computada de tórax: normal (5/13), patrón intersticial (5/13), vidrio esmerilado (2/13) y fibrosis (1/13). Espirometría: normal (7/13), restrictiva (4/13), obstructiva (1/13) y no efectuada (1/13). Tratamiento durante la fase aguda: bolos de metilprednisolona (7/13) o prednisona (6/13) o hidrocortisona (1/13). En la fase de mantención se administró: prednisona (13/13) más un inmunosupresor, azathioprina (12/13), hidroxicloroquina (1/13), micofenolato (1/13), más budesonida MDI (13/13). Ocho pacientes detuvieron los sangrados. Dos pacientes fallecieron y hubo cinco embarazos de curso fisiológico en 3 adolescentes. Se observó: a) diferentes modalidades de presentación que retrasaron el diagnóstico; b) gran exposición a pesticidas; c) mejor pronóstico si el diagnóstico y el tratamiento eran precoces, también en niñas adolescentes; d) la mayoría detuvo los episodios de sangrado.
Idiopathic pulmonary hemosiderosis (IPH) is a cause of diffuse alveolar hemorrhage. OBJECTIVE: to describe the evolution of children with IPH in our institution. Retrospective monitoring with a follow-up protocol was carried out. 13 patients, seven males, were recruited. From an agricultural area (6/13). Not all of patients had the complete diagnostic triad: cotton infiltrates (9/13), anemia (11/13), hemoptysis (9/13). Hemosiderin-laden macrophages counting in the bronchoalveolar lavage fluid was over 30% in all the patients. Computed chest tomography was informed as normal (5/13), interstitial pattern (5/13), ground glass (2/13) and fibrosis (1/13). Spirometry: normal (7/13), restrictive (4/13), obstructive (1/13) and not performed (1/13). Treatment during the acute phase: bolus of methylprednisolone (7/13) or prednisone (6/13) or hydrocortisone (1/13). In the maintenance phase: prednisone (13/13) plus an immunosuppressant, azathioprine (12/13), hydroxychloroquine (1/13), mycophenolate (1/13), plus budesonide MDI (13/13). Eight patients stopped the bleeding episodes. Two patients died and there were five physiological pregnancies in 3 adolescents. It was observed:(a) different modes of IPH presentation that delayed its diagnosis; (b) large exposure to pesticides; (c) prognosis improved if diagnosis and treatment were early, also in adolescent girls; (d) most of the patients stopped the bleeding episodes.

Abstract Objective To study a sample of rheumatoid arthritis (RA) patients for their gynecological/obstetric history and compare them to controls to determine their influences on number of pregnancies, menarche, menopause and reproductive years following RA onset. Methods This is a cross-sectional study of 122 RA patients and 126 controls. Patients and controls were questioned about age of menarche, age of menopause, number of pregnancies and abortions. Reproductive years were calculated as the difference between age at menopause and age at menarche. For comparison, we used the Mann-Whitney, unpaired t, chi-squared, and Spearman tests. The adopted significance was 5%. Results In the RA patients with disease beginning in the postmenopausal years, the period of reproductive years (age at menopause - age of menarche) showed a positive correlation with age at disease onset (rho=0.46; 95% confidence interval [CI]=0.20- 0.55 with p=0.0008). The number of pregnancies was higher in patients with postmenopausal disease onset when compared with those with premenopausal disease onset (median of 3 with interquartile range [IQR]=2-4 versus median of 2 with IQR=1-3; p=0.009), and RA patients had more pregnancies than controls (p=0.0002). Conclusion The present study shows that, in our population, the duration of reproductive years and the number of pregnancies are linked to the onset of RA.
Resumo Objetivo Estudar uma amostra de pacientes com artrite reumatoide (AR), com investigação da história ginecológica e obstétrica, comparando-a com controles, visando conhecer suas influências no número de gestações, menarcas, menopausa e anos reprodutivos no início da AR. Métodos Trata-se de um estudo transversal de 122 pacientes com AR e 126 controles. Pacientes e controles foram questionados sobre idade da menarca, idade da menopausa, número de gestações e abortos. Os anos reprodutivos foram calculados com a diferença entre a idade da menopausa e a idade da menarca. Para comparação, foram utilizados Mann Whitney, Teste t não pareados, Teste qui-quadrado e teste de Spearman. A significância adotada foi de 5%. Resultados Nas pacientes comAR e início da doença na pós-menopausa, o período de anos reprodutivos (idade da menopausa - idade da menarca) apresentou correlação positiva com a idade de início da doença (rho=0,46; intervalo de confiança de 95% [IC95%]=0,20-0,55 com p=0,0008). O número de gestações foi maior nas pacientes cominício da doença no período pós-menopausa quando comparadas às pacientes em pré-menopausa (mediana de 3 comintervalo interquartil [IIQ]=2-4 versusmediana de 2 com IIQ=1-3; p=0,009). Nas pacientes com AR, foi observado ummaior número de gestações do que no grupo controle (p=0,0002).

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree affected with autosomal dominant late-onset non-syndromic hearing loss (NSHL).@*METHODS@#Clinical data of the pedigree were collected. Genomic DNA was extracted from peripheral blood samples of the proband and other family members. Trio whole exome sequencing was carried out for 19 396 genes to identify potential pathogenic variants. Sanger sequencing was carried out to verify the candidate variant in the pedigree.@*RESULTS@#The proband and his father were found to carry a c.1183+1delG p.? variant of the DFNA5 gene. The variant was confirmed to be co-segregating with the disease phenotype in the pedigree.@*CONCLUSION@#The c.1183+1delG p.? variant of the DFNA5 gene probably underlay the late onset NSHL in this pedigree. Above finding has enabled accurate genetic counseling for this pedigree.

Background@#The incidence rate of Angle Class I and Class II malocclusions in mixed dentition is higher than Class III. In orthodontic interceptive treatment, it is necessary to identify pubertal growth spurt peak individually because the best growth modification could be obtained during this period. One of the methods in assessing the pubertal growth spurt peak is cervical vertebrae maturation (CVM), which is done using a lateral cephalometric radiograph. CVM evaluates potential growth and skeletal maturity by assessing cervical vertebrae anatomy. Identifying the duration of growth spurt peak on both malocclusion classes is the most pivotal aspect of optimizing remodeling and correction of children’s malocclusion. @*Objective@#Distinguishing the duration of pubertal growth spurt peak of children with Angle Class I and II malocclusions based on CVM analysis in Deutero-Malay children so that it can be used in determining optimal orthodontic treatment plan and timing in children with Class I and Angle II malocclusion for Deutero-Malay children. @*Methods@#Analytical observational with cross-sectional approach was applied using lateral cephalometric radiographic images from patients’ medical records attending or had attended orthodontic treatment in the Pediatric Dentistry Clinic, Airlangga University Dental Hospital, Surabaya, Indonesia, in 2014-2019 that met the inclusion criteria and were analyzed with Baccetti’s method of CVM analysis. This study involved 66 conventional lateral cephalometric photographs that were selected using total sampling. The data were analyzed using Independent T-Test and Mann Whitney U Test. @*Result@#The duration of pubertal growth spurt peak in Angle Class I and II malocclusions was 11 and 7 months, respectively. The age of onset for Class I with CS3 was 9 years and 5 months, while for Angle Class II malocclusion starts entering the stage at 10 years 3 months of age, while for CS4 skeletal maturity we found that the age of onset for subjects with Angle Class I and II were 11 years 2 months and 12 years 4 months, respectively. The average duration of the pubertal growth spurt peak in female and male patients was 11.3 months and 18.2 months, respectively. All of these results were statistically significant (p ≤ 0.001) and representative of the population, in this case, Deutero-Malays. @*Conclusion@#Four-month differences in the duration of pubertal growth spurt peak of children with Angle Class I and II were found. This may lead to a shorter treatment duration of 4 months in children with Angle Class II malocclusion when compared to children with Angle Class I malocclusion. Angle Class II malocclusion exhibit shorter pubertal growth spurt peak duration, which may account for the difference in mandibular growth on the two malocclusion classes.

La diabetes mellitus tipo 2 (DM2), habitualmente asociada a adultos en edad media y adulto mayor, ha presentado un aumento en su incidencia en pacientes menores de 40 años, lo que se conoce como DM2 de inicio en paciente joven. Varios estudios sugieren que este tipo de diabetes presenta no sólo un deterioro más rápido de las células beta-pancreáticas en comparación con la DM2 de inicio más tardío, sino que también un mayor riesgo de complicaciones que pacientes con DM Tipo1, lo que sugiere una variable independiente de los años de exposición a la enfermedad y por tanto, un fenotipo más agresivo. Por otra parte, hay evidencia que afirma que existen grupos poblacionales en mayor riesgo de desarrollar esta patología, particularmente ciertas etnias. En el presente trabajo se exponen los principales hallazgos de una reciente revisión del tema y se los compara con los datos nacionales disponibles. Dada la alta prevalencia de DM2 en la población chilena y la escasa cantidad de estudios epidemiológicos de calidad que permitan conocer nuestro panorama con mayor precisión, es que se destaca la importancia de estos últimos para poder tomar medidas de salud pública adecuadas.
Type 2 diabetes mellitus type 2 (T2DM), commonly associated with the middle to old aged adults group, has shown an increase in incidence in patients younger than 40 years old, which is known as young-onset type 2 diabetes mellitus. Several studies suggest that this type of diabetes not only exhibits a faster deterioration of the beta-pancreatic cells in comparison with type 1 diabetes mellitus patients, but also a greater risk of complications not regarding the time of exposure to the disease, therefore a more aggressive phenotype. Otherwise, there is evidence which asserts that some population groups are in mayor risk of developing this disease, especially certain ethnics. In this work it is exposed the main findings of a recent review of the subject and it is contrasted with available national data. Given the high prevalence of T2DM in the chilean population and the little amount of epidemiological high-quality studies that allows us to know our outlook with greater precision, it is highlighted the need for them in order to make adequate public health decisions.

Abstract Objective Congenital clubfoot (PTC) is a congenital orthopedic condition often requiring intensive treatment; little is known about the impact of such treatment on motor development. The present study assessed whether gait development is later in patients with PTC treated with the Ponseti method in comparison to a control group and analyzed possible related factors. Methods Patients born at term, < 6 months old, not submitted to previous treatment and with a minimum follow-up period of 24 months were included. The control group consisted of patients with no musculoskeletal disorders seen during the present study. Results The study group consisted of 97 patients, whereas the control group had 100 subjects. The mean age at gait start was 14.7 ± 3.2 months in the study group and 12.6 ± 1.5 months in the control group (p< 0.05). Factors related to late gait included age at beginning of treatment > 3 weeks, number of plaster cast changes > 7, recurrence and nonperformance of Achilles tenotomy. Age at beginning of treatment > 3 weeks was related to a greater number of plaster cast changes. Gender and laterality were not related to late gait development. Conclusion Congenital clubfoot patients treated with the Ponseti method show independent walking approximately 2 months later than the control group. Delayed treatment, higher number of plaster cast changes, recurrence and nonperformance of Achilles tenotomy were related to late gait.
Resumo Objetivo O pé torto congênito (PTC) é uma das alterações ortopédicas congênitas que mais frequentemente necessita tratamento intensivo, e pouco se sabe o impacto desse tratamento no desenvolvimento motor. O presente estudo buscou avaliar se pacientes portadores de PTC tratados pelo método de Ponseti desenvolvem a marcha mais tardiamente comparado a um grupo controle e analisar possíveis fatores relacionados. Métodos Incluídos pacientes nascidos a termo, com < 6 meses de idade, sem tratamento prévio e com seguimento mínimo de 24 meses. O grupo controle foi de pacientes sem alterações musculoesqueléticas, atendidos no mesmo período da realização do presente estudo. Resultados Um total de 97 pacientes formaram o grupo de estudo e 100 o grupo controle. A média de idade no início da marcha no grupo de estudo foi de 14,7 ± 3,2 meses, e 12,6 ± 1,5 meses (p< 0,05) no grupo controle. Fatores relacionados à marcha tardia foram: idade de início do tratamento > 3 semanas, número de trocas gessadas > 7, recidiva e não realização da tenotomia de Aquiles. Idade de início do tratamento > 3 semanas esteve relacionada a maior número de trocas de gessos. Gênero e lateralidade não tiveram relação com a marcha tardia. Conclusão Pacientes com PTC tratados com o método de Ponseti apresentam marcha independente aproximadamente 2 meses mais tarde do que o grupo controle. Início mais tardio do tratamento, maior número de trocas de gessos, recidiva e não realização da tenotomia de Aquiles foram relacionados com atraso da marcha.

Resumen El consumo de Sustancias psicoactivas (SPs) es un problema de salud mundial que afecta particularmente a los adolescentes. Por lo tanto, el conocimiento del contacto que los jóvenes tienen con las SPs, permitirá el desarrollo de políticas de prevención. El objetivo del trabajo fue evaluar el contacto con SPs de estudiantes secundarios de Rosario y alrededores. Entre el 2013 y el 2016, contestaron de forma anónima un cuestionario 1064 estudiantes, observándose un aumento significativo del consumo de SPs en el año 2016. Cuando se excluyen el consumo de tabaco y alcohol (SPs legales) el porcentaje permanece constante. El aumento observado se debe al consumo de SPs tales como alcohol y tabaco. Se observó una disminución de la edad de inicio así como un cambio en los porcentajes y patrones de consumo. La SP más consumida fue el alcohol seguida de tabaco o marihuana. Los cambios observados podrían estar relacionados con las edades y los años de cursado de los estudian tes encuestados.
Abstract. Adolescence is characterized by anxiety, peer-pressure, identity search, etc. All these features contribute to experiment with Psychoactive Drugs (P.D.). P.D. use is a global health problem that has its onset during adolescence. The developing of prevention policies according to a specific population needs the knowledge of the levels and patterns of P.D. use. The goal of the present work was to evaluate P.D.'s level of contact and patterns of use among high school students in Rosario (Argentina). Between 2013 and 2016, a total of 1064 students were surveyed. The results showed that P.D. use (at least once in a lifetime) was significantly higher in 2016 compared to previous years. However, when the use of legal vs illegal P.D. was discriminated we found that such increase was due to higher use of alcohol and tobacco; while the illegal P.D. use remained constant. Moreover, in 2016 we found a decrease in the age of onset as well as a change in the patterns of P.D use. However, all these results must be analyzed taking into account intrinsic differences of the sample.

METODOLOGÍA: Estudio observacional retrospectivo de pacientes diagnosticados con TEA en el Centro de Terapia del Comportamiento. RESULTADOS: 28 pacientes (24 hombres) con diagnóstico de TEA. Mediana de edad de inicio de síntomas de 24 meses y de diagnóstico de 62,5 meses. No existe una correlación entre la edad de pesquisa de síntomas y del diagnóstico (r2=0,1). CONCLUSIONES: No hubo relación entre edad de pesquisa de síntomas por los cuidadores y diagnóstico de TEA. Este estudio refleja la necesidad de ampliar el conocimiento poblacional sobre sintomatología temprana de TEA, siendo una herramienta de salud pública para lograr el manejo precoz y mejorar el pronóstico de estos sujetos.
INTRODUCTION: Early intervention in autism spectrum disorder (ASD) has shown to be essential for better long-term prognosis. Significant delays have been described between symptom assessment and diagnosis, deferring therapy initiation. OBJECTIVE: To relate the moment of symptom detection by caregivers and the medical diagnosis of ASD. METHODOLOGY: Observational retrospective study, including patients diagnosed with ASD at a private behavioral therapy center. Results: 28 patients (24 male) with diagnosis of ASD. Median age of symptom assessment was at 24 months and of diagnosis at 62.5 months. There is no relation between the age of symptoms assessment and diagnosis (r2 = 0.1). CONCLUSIONS: There was no relationship between the age at which symptoms were detected by caregivers and medical diagnosis of ASD. This study reflects the need to increase the awareness about early symptoms of ASD, being a public health tool to achieve early management and improve the prognosis of these subjects.

La miastenia gravis (MG) es una enfermedad autoinmune mediada por anticuerpos dirigidos contra proteínas post sinápticas de la unión neuromuscular. El objetivo de este estudio fue describir los aspectos clínicos, epidemiológicos y serológicos de pacientes con MG en un Hospital Público de la Ciudad de Buenos Aires. Se realizó un análisis retrospectivo sobre 190 enfermos con diagnóstico de MG. La edad media de inicio de la enfermedad fue de 38 años; 57 (30%) fueron MG de inicio tardío (inicio de síntomas > 50 años). La relación mujer/hombre fue 1.7/1. La enfermedad se inició más tempranamente en las mujeres que en los hombres, media 32 vs. 48 años (p < 0.0001). La MG familiar autoinmune representó el 3.2 % (6 casos). La forma más común de presentación fue con manifestaciones oculares puras (52%). El 12.1% (23/190) fue considerada MG ocular en el seguimiento. La MG asociada a timoma se presentó en 22 casos (11.6%). El 27.1% presentó otra enfermedad autoinmune asociada, siendo las tiroideas las más frecuentes. El 81.4% tuvo anticuerpos anti-receptores de acetilcolina (ACRA) positivos y 22.7% de los ACRA negativos fueron positivos para anticuerpos anti-tirosina quinasa musculo especifica (anti-MusK). La evolución clínica fue favorable, hallándose más de la mitad de los casos en remisión o manifestaciones mínimas en la última visita. La mayoría requirió inmunosupresión para control de la sintomatología, el 78% recibió corticoides y el 48% un inmunosupresor no esteroideo.
Myasthenia gravis (MG) is an antibody-mediated autoimmune disease of the neuromuscular junction. The aim of this study was to evaluate clinical, epidemiological and serological features of patients with MG in a Public Hospital of Buenos Aires City. A retrospective analysis of 190 patients diagnosed with MG was performed. The mean age of MG onset was 38 years, 30% had late-onset MG (onset age > 50 years). The female/male ratio was 1.7 / 1. Disease started earlier in women than in men, mean 32 vs. 48 years (p < 0.0001). Familial autoimmune MG represented 3.2% of the cases. Most of the patients initiated their disease with a pure ocular form (52%). 12.1% (23/190) were considered ocular MG at follow-up. Thymoma-associated MG represented 11.6% of cases. 27.1% had other associated autoimmune disease, thyroid disorders were the most frequent. 81.4% were anti-acetylcholine receptor antibody (AChR-ab) positive MG; 22.7% of AChR-ab negatives were positive for anti-muscle specific kinase (MusK) antibodies. Clinical outcome was relatively good; more than half of cases were in remission or minimal manifestations at the last visit. The majority of patients required immunosuppression to control the symptoms, 78% received corticosteroids and 48%, a non-steroidal immunosuppressant.

Abstract Background: Cytochrome P450 2J2 is mostly expressed in extrahepatic tissues; it metabolizes arachidonic acid to epoxyeicosatrienoic acids, with various cardio protective and anti-inflammatory effects. CYP2J2 polymorphism has been identified as a risk factor for cardiovascular diseases, but its association with psoriasis remains unknown. Objective: To evaluate CYP2J2 polymorphism as a risk factor for psoriasis in the Turkish population. Methods: There were 94 patients with psoriasis and 100 age- and sex-matched healthy controls included in the study. Detailed demographic and clinical characteristics were recorded, and Psoriasis Area and Severity Index (PASI) scores were calculated for psoriasis patients. Venous blood samples were collected from all the participants and CYP2J2 50G>T (rs890293) polymorphism was analyzed using polymerase chain reaction (PCR). Results: Both T allele and TT + GT genotype frequencies were increased in psoriasis vulgaris patients compared to the control group (p = 0.024 and p = 0.029 respectively, OR = 2.82, 95% CI: 1.11-7.15) No association between CYP2J2 polymorphism and clinical features of psoriasis was identified. Study limitations: A limited number of patients were included in the study. Conclusion: CYP2J2 50G>T (rs890293) polymorphism was associated with an increased risk for PsV in the Turkish population.

BACKGROUND: Recently, the prevalence of food allergies during childhood is increasing, with fruits being common allergens. However, data on allergens that cause fruit and vegetable allergies and pollen-food allergy syndrome (PFAS) in childhood are relatively few. This study aimed to examine the allergens in fruit and vegetable allergies in pediatric patients and to determine the association between fruit and vegetable allergies and PFAS.OBJECTIVE: This study aimed to examine the current status of fruit and vegetable allergies in Japanese children.METHODS: This was a multicenter case series observational study. The participants included children aged <15 years who developed allergic symptoms after eating fruits and vegetables and subsequently received treatment in the Pediatric Department of 6 hospitals in the Osaka Prefecture in Japan during the study period from August 2016 to July 2017. Participants' information was obtained using a questionnaire, and data were obtained by performing several types of allergy tests using blood samples.RESULTS: A total of 97 children (median age, 9 years; 56 males) were included in the study. Apple was the most common allergen, followed by peach, kiwi, cantaloupe, and watermelon. A total of 74 participants (76%) exhibited allergic symptoms due to PFAS; moreover, pathogenesis-related protein-10 (PR-10) was the most common allergen superfamily. On the contrary, in the group where neither PR-10 nor profilin was sensitized, kiwi and banana were the most common allergens, and the age of onset was lower than that in the PFAS group. Specific antibody titer was significantly associated with Birch for Bet v1 and latex for Bet v2 (r = 0.99 and r = 0.89).CONCLUSION: When we examine patients with fruit and vegetable allergies, we should first consider PFAS even in childhood specifically for children greater than 4 years old.
