RESUMO
INTRODUCTION: The spectrum of clinical presentation of Fabry disease (FD) in women is broad and challenging. The aim is to evaluate the effectiveness of an alternative screening method for FD in women. METHODS: A collaborative multicenter cross-sectional study to evaluate the sensitivity and specificity of the combination of two tests (α-GAL enzyme activity assay and lyso-GL3 assay) for the diagnosis of FD in women. We included women with chronic kidney disease (CKD) stages 3 to 5, receiving conservative treatment or on dialysis programs, from different nephrology services in Brazil. RESULTS: We evaluated 1874 patients that underwent blood collection for α-GAL and lyso-GL3 assays. Isolated decreased α-GAL enzyme activity was found in 64 patients (3.5%), while isolated increased lyso-GL3 levels were found in 67 patients (3.6%), with one patient presenting alterations in both tests. All cases with low α-GAL enzyme activity and/or increased lyso-GL3 levels underwent genetic analysis for FD variants (132 performed GLA genetic test). Low α-GAL enzyme activity had higher sensitivity and specificity to detect FD compared to the other measures (elevated lyso-GL3 alone or both altered). The negative predictive value (NPV) of α-GAL activity was 99%, and the positive predictive value (PPV) was 9.2%. For lyso-GL3 assay, the specificity was 99.7% and the PPV was 2.9%, therefore considered inferior to α-GAL assay. Both assays altered, had higher PPV (100%) and higher NPV (99.7%) considered the best method. We found 7 cases of GLA gene variants found, resulting in an initial prevalence of 0.37% for FD in this sample female population. CONCLUSION: This study contributes to the diagnostic value of the biomarkers α-GAL and lyso-GL3 in the context of FD in women with CKD. The combination of these biomarkers was an effective approach for the diagnosis of the disease, with high PPV and NPV.
RESUMO
Mucopolysaccharidosis type IIIB (MPS IIIB) is caused by deficiency of alpha-N-acetylglucosaminidase, leading to storage of heparan sulphate. The disease is characterized by intellectual disability and hyperactivity, among other neurological and somatic features. Here we studied retrospective data from a total of 19 MPS IIIB patients from Brazil, aiming to evaluate disease progression. Mean age at diagnosis was 7.2 years. Speech delay was one of the first symptoms to be identified, around 2-3 years of age. Behavioral alterations include hyperactivity and aggressiveness, starting around age four. By the end of the first decade, patients lost acquired abilities such as speech and ability to walk. Furthermore, as disease progresses, respiratory, cardiovascular and joint abnormalities were found in more than 50% of the patients, along with organomegaly. Most common cause of death was respiratory problems. The disease progression was characterized in multiple systems, and hopefully these data will help the design of appropriate clinical trials and clinical management guidelines.
RESUMO
Mucopolysaccharidosis type IIIB is a rare autosomal recessive disorder characterized by deficiency of the enzyme N-acetyl-alpha-d-glucosaminidase (NAGLU), caused by biallelic pathogenic variants in the NAGLU gene, which leads to storage of heparan sulfate and a series of clinical consequences which hallmark is neurodegeneration. In this study clinical, epidemiological, and biochemical data were obtained from MPS IIIB patients diagnosed from 2004-2019 by the MPS Brazil Network ("Rede MPS Brasil"), which was created with the goal to provide an easily accessible and comprehensive investigation of all MPS types. One hundred and ten MPS IIIB patients were diagnosed during this period. Mean age at diagnosis was 10.9 years. Patients were from all over Brazil, with a few from abroad, with a possible cluster of MPS IIIB identified in Ecuador. All patients had increased urinary levels of glycosaminoglycans and low NAGLU activity in blood. Main clinical symptoms reported at diagnosis were coarse facies and neurocognitive regression. The most common variant was p.Leu496Pro (30% of alleles). MPS IIIB seems to be relatively frequent in Brazil, but patients are diagnosed later than in other countries, and reasons for that probably include the limited awareness about the disease by health professionals and the difficulties to access diagnostic tests, factors that the MPS Brazil Network is trying to mitigate.

OBJECTIVES: This work aims to describe oral health conditions, eating habits, and oral hygiene in pediatric and adolescent patients with atopic dermatitis and correlate them with the severity of the Scoring Atopic Dermatitis (SCORAD). Also, we aim to estimate the effect of several variables on the diagnosis of dental caries in these patients. MATERIAL AND METHODS: A total of 92 children and adolescents with atopic dermatitis had their oral cavities examined. The effect of independent variables on the diagnosis of dental caries (outcome) was assessed using multiple binary logistic regression model. RESULTS: Mild patients presented higher score of decayed, missing, and filled teeth in permanent dentition than moderate patients (p = 0.040). In the multivariable regression final model, the covariates using inhaled corticoid (OR = 6.4; p = 0.003), type of teething [deciduous dentition (OR = 7.9; p = 0.027) and mixed dentition (OR = 10.5; p = 0.007)], and brushing quality [poor mechanical control (OR = 10.6; p < 0.0001)] demonstrated significant direct effect on the diagnosis of dental caries. CONCLUSIONS: Our findings suggest that the presence of dental biofilm, use of inhaled corticoid, and type of teething are related to the presence of caries in atopic dermatitis patients.

INTRODUCTION: This study aims to assess the impact of paediatric benign and malignant solid tumours and its treatment on the health-related quality of life of children and adolescents who were followed up in a Reference Center in Pediatric Oncology in Rio de Janeiro. METHODS: It is a prospective cohort study. Quality of life assessment was performed using the PedsQL™ 4.0 Generic Core Scales and PedsQL™ 3.0 Cancer Module protocols three times: during hospital admission (T1), 6 months after admission (T2) and 1 year after admission (T3). RESULTS: We evaluated 132 patients, 59 men and 73 women, aged 2-17 years. In PedsQL™4.0, the Emotional Functioning scale was the one with the worst scores, while the scores on the Social Functioning scale was the best. In PedsQL™ 3.0, the worst domains were Procedural Anxiety and Worry. Patients with malignant bone tumours had the worst health-related quality of life. The group who received only surgery had better results. Total scores of PedsQL™4.0 and PedsQL™ 3.0 improved between T1 and T3. CONCLUSION: Children and adolescents with malignant and benign neoplasms undergo changes in quality of life as a result of the disease and treatment, but an improvement has been observed over time.

BACKGROUND Phenylketonuria (PKU) is an inborn error of metabolism caused by mutations in the phenylalanine hydroxylase (PAH) gene. When untreated, PKU leads to a significant intellectual deficiency. Although early initiation of dietary therapy allows normal cognitive development, low adherence to treatment may result in neuropsychological deficits, including attention problems. This study was performed to evaluate emotional and behavioral problems in early-treated children and adolescents with PKU using the Child Behavior Checklist - CBCL/6-18 answered by parents. MATERIAL AND METHODS The study included 36 PKU patients. The mean scores of internalizing, externalizing, and total problems, syndrome scales, and DSM-IV-oriented scales of patients were compared with those of controls. An analysis to evaluate the importance of adherence to treatment and presence of intellectual disability was also performed. RESULTS There were no significant differences between patients and controls for almost all CBCL/6-18 scales, with the exception of the Attention Problem Scale - CBCL-APS. The mean (±SD) of the CBCL-APS scores of patients (7.86±5.33) was considerably higher than the mean of the controls (6.07±4.37; p=0.016), but not different from the mean of a matched control subsample (6.69±4.46; p=0.316). The difference between the mean of the scores of DSM-IV/ADHD scale of patients (6.72±4.07) and controls (5.73±3.56; p=0.102) was not significant. Non-adherence to treatment and intellectual disability had a negative impact on both CBCL-APS and DSM-IV/ADHD scale scores. CONCLUSIONS Our findings indicate a significant prevalence of parents' complaints of attention problems and hyperactivity in non-adherent to treatment and intellectually low performing patients with PKU.

Recently, we defined a minimal overlapping region for causal Xp11.22 copy number gains in males with intellectual disability (ID), and identified HECT, UBA and WWE domain-containing protein-1 (HUWE1) as the primary dosage-sensitive gene, whose overexpression leads to ID. In the present study, we used this minimal interval to search for HUWE1 copy number variations by quantitative polymerase chain reaction in a large cohort of Brazilian males with idiopathic ID. We detected two unrelated sporadic individuals with syndromic ID carrying unique overlapping duplications encompassing HUWE1. Breakpoint junction analysis showed a simple tandem duplication in the first patient, which has probably arisen by microhomology-mediated break-induced repair mechanism. In the second patient, the rearrangement is complex having an insertion of an intrachromosomal sequence at its junction. This kind of rearrangement has not been reported in Xp11.22 duplications and might have emerged by a replication- or recombination-based mechanism. Furthermore, the presence of infantile seizures in the second family suggests a potential role of increased KDM5C expression on epilepsy. Our findings highlight the importance of microduplications at Xp11.22 to ID, even in sporadic cases, and reveal new clinical and molecular insight into HUWE1 copy number gains.

Introduction Turner syndrome (TS) affects â¼ 1 in 2,500 live births. The presence of hearing alterations is one of the comorbidities found in this syndrome. Objective The present study aimed to evaluate the central auditory abilities in TS and to associate the alterations found with the cytogenetic pattern of the syndrome. Methods We included children and adults aged 9 to 39 years old, diagnosed with TS, with numerical or structural alterations of sex chromosomes in their karyotype. A battery of behavioral tests of central auditory processing (CAP) was performed, including a test within the modalities: monoaural low-redundancy, dichotic listening, binaural interaction, and temporal processing (resolution and ordering). We studied auditory skills in the total sample and in the sample stratified by age, divided into groups: G1 (9 to 13 years old), G2 (14 to 19 years old), and G3 (20 to 31 years old). For the association of the cytogenetic pattern, the division was T1 (chromosome monosomy X), and T2 (other TS cytogenetic patterns). Statistical analysis presented data expressed as median and interquartile range for numerical data and as frequency and percentage for categorical data. Results We found alterations in four auditory skills in the three age groups, but there was a statistically significant difference between the age groups only in the Gaps in Noise Test (GIN) ( p -value = 0.009). Regarding karyotype, a greater number of alterations in the T1 cytogenetic pattern (chromosome monosomy X) was observed in four auditory skills, but without a statistically significant difference. Conclusion The alterations found point to an impairment in CAP in TS.
RESUMO
Turner syndrome (TS) is caused by a complete or partial absence of an X or Y chromosome, including chromosomal mosaicism, affecting 1 in 2500 female live births. Sister chromatid exchange (SCE) is used as a sensitive indicator of spontaneous chromosome instability. Cells from mosaic patients constitute useful material for SCE evaluations as they grow under the influence of the same genetic background and endogenous and exogenous factors. We evaluated the proliferation dynamics and SCE frequencies of 45,X and 46,XN cells of 17 mosaic TS patients. In two participants, the 45,X cells exhibited a proliferative disadvantage in relation to 46,XN cells after 72 h of cultivation. The analysis of the mean proliferation index (PI) showed a trend for a significant difference between the 45,X and 46,X+der(X)/der(Y) cell lineages; however, there were no intra-individual differences. On the other hand, mean SCE frequencies showed that 46,X+der(X) had the highest mean value and 46,XX the lowest, with 45,X occupying an intermediate position among the lineages found in at least three participants; moreover, there were intra-individual differences in five patients. Although 46,X+der(X)/der(Y) cell lineages, found in more than 70% of participants, were the most unstable, they had a slightly higher mean PI than the 45,X cell lineages in younger (≤17 years) mosaic TS participants. This suggests that cells with a karyotype distinct from 45,X may increase with time in mosaic TS children and adolescents.
RESUMO
Background: Sarcomeric hypertrophic cardiomyopathy (HCM) must be differentiated from phenotypically similar conditions because clinical management and prognosis may greatly differ. Patients with unexplained left ventricular hypertrophy require an early, confirmed genetic diagnosis through diagnostic or predictive genetic testing. We tested the feasibility and practicality of the application of a 17-gene next-generation sequencing (NGS) panel to detect the most common genetic causes of HCM and HCM phenocopies, including treatable phenocopies, and report detection rates. Identification of transthyretin cardiac amyloidosis (ATTR-CA) and Fabry disease (FD) is essential because of the availability of disease-specific therapy. Early initiation of these treatments may lead to better clinical outcomes. Methods: In this international, multicenter, cross-sectional pilot study, peripheral dried blood spot samples from patients of cardiology clinics with an unexplained increased left ventricular wall thickness (LVWT) of ≥13 mm in one or more left ventricular myocardial segments (measured by imaging methods) were analyzed at a central laboratory. NGS included the detection of known splice regions and flanking regions of 17 genes using the Illumina NextSeq 500 and NovaSeq 6000 sequencing systems. Results: Samples for NGS screening were collected between May 2019 and October 2020 at cardiology clinics in Colombia, Brazil, Mexico, Turkey, Israel, and Saudi Arabia. Out of 535 samples, 128 (23.9%) samples tested positive for pathogenic/likely pathogenic genetic variants associated with HCM or HCM phenocopies with double pathogenic/likely pathogenic variants detected in four samples. Among the 132 (24.7%) detected variants, 115 (21.5%) variants were associated with HCM and 17 (3.2%) variants with HCM phenocopies. Variants in MYH7 (n=60, 11.2%) and MYBPC3 (n=41, 7.7%) were the most common HCM variants. The HCM phenocopy variants included variants in the TTR (n=7, 1.3%) and GLA (n=2, 0.4%) genes. The mean (standard deviation) ages of patients with HCM or HCM phenocopy variants, including TTR and GLA variants, were 42.8 (17.9), 54.6 (17.0), and 69.0 (1.4) years, respectively. Conclusions: The overall diagnostic yield of 24.7% indicates that the screening strategy effectively identified the most common forms of HCM and HCM phenocopies among geographically dispersed patients. The results underscore the importance of including ATTR-CA (TTR variants) and FD (GLA variants), which are treatable disorders, in the differential diagnosis of patients with increased LVWT of unknown etiology.
RESUMO
OBJECTIVE: To present a mucopolysaccharidosis (MPS) case series evaluating oral manifestations (clinical and radiographic), oral health status and discussing its implications. PATIENTS AND METHODS: All patients with MPS attending the Genetics clinic/Brazil were evaluated by means of anamnesis, clinical and radiographic examinations. RESULTS: The final sample consisted of 12 subjects (nine males and three females), with ages ranging from 3-31 years old. Concerning oral health, it was observed high levels of caries and periodontal problems. About oral manifestations, this study clinically observed more cases of delayed tooth eruption, thickness of alveolar process and thick lips. Radiographically, it was observed alterations on condyle, mandibular ramus and joint fossa. CONCLUSION: The dental changes in MPS population are high and consequently it is important to know them for differential diagnoses, early treatment intervention, prevention and education of both patients and parents/caregivers about oral health.

OBJECTIVES: To verify the agreement between the Alberta Infant Motor Scale assessment and maternal perception of the motor development in full-term infants. METHODS: This is a cross-sectional study involving 161 infants and mothers. Children were assessed with the Alberta Infant Motor Scale (AIMS) for motor developmental classification. Mothers completed questionnaires aiming to identify maternal profiles and impressions about their children's development. The kappa test was used to analyze the concordance between AIMS and mother perceptions. RESULTS: A total of 83.2% of the sample was classified as typically developing and 16.8% as suspected or delayed development. The maternal impression indicates that 77% of infants are developing typically, 19.9% perceived their infants' development as advanced, and 3.1% delayed development. There was low agreement between the mothers' perceptions and AIMS classifications (kappa = 0.153). CONCLUSIONS: Maternal perception of their infant's development was unsatisfactory for evaluation of motor development because their perceptions did not agree with the findings of the AIMS.

PURPOSE: The goal of this study is to investigate the efferent auditory pathways inhibition in Turner's syndrome and to relate it to the cytogenetic profile. METHODS: This is a cross-sectional study with a comparison group. A sample with 94 participants divided into two groups: The study group was a sample of 40 patients diagnosed with Turner's syndrome (17.6 years of age). The control group was composed of 54 volunteers (18.9 years of age), female, without syndrome. The selected individuals were submitted to efferent auditory pathways inhibition research. RESULTS: The mean of the inhibitory effect of the efferent auditory pathway in the study group in the right ear was 0.4 dB and in the comparison group it was 1.9 dB, however in the left ear the mean of the inhibitory effect of the efferent auditory pathway was 1.4 dB in the study group and 0.8 dB in the comparison group. The inhibitory effect of the efferent auditory pathway was present in 14 individuals with monosomy and in 15 with other cytogenetic alterations. CONCLUSIONS: In the study group, the efferent auditory pathways inhibition value was significantly higher in the left ear and significantly lower than the control group in the right ear. There was no significant difference in efferent auditory pathways inhibition of right ear and left ear between the karyotype types.

INTRODUCTION: Turner syndrome is a frequent genetic disorder that affects female individuals and covers a large phenotypic variability. Scientific literature suggests an association between hearing loss and Turner syndrome, but it remains a controversial topic. OBJECTIVE: To associate the cytogenetic alteration with the audiometric profile of individuals with Turner syndrome. METHODS: Cross-sectional study, with a hospital-based, convenience sample. Patients diagnosed with Turner syndrome were included and those with difficulty understanding the audiometry and/or other associated syndromes were excluded. The participants were studied with pure tone audiometry. RESULTS: Of the 65 patients included, 36.9% had X chromosome monosomy and 63.0% had other alterations. Regarding the audiometry, 64.6% had normal thresholds and 35.3% had hearing impairment. Of these, 30.4% had hybrid hearing loss, 26.0% alteration at 6 and/or 8kHz, 17.3% had conductive hearing loss, 13.0% sensorineural loss and 13.0% had mixed hearing loss. We observed that the mild degree was the most frequent one. There was no statistically significant association between the cytogenetic type of Turner syndrome and the presence or absence of hearing loss, or with the type and degree of hearing loss. CONCLUSION: The cytogenetic alteration in Turner syndrome was not associated with the audiometric profile, which showed variability regarding the type and degree of hearing loss.

BACKGROUND: Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder with a prevalence of 1:3000 births and a wide variety of clinical manifestations. Cutaneous neurofibromas (cNF) are among the most common visible manifestations of NF1 and present a major clinical burden for patients. NF1 patients with cNF often report decreased quality of life, emotional well-being and physical comfort. Developing effective medical therapies for cNF has been identified as a priority for the majority of adults with NF1. METHODS: The study was an open, controlled and prospective proof-of-concept clinical trial. The topical treatment consisted of two steps: cNF microporation using a laser device followed by topical application of one drop of diclofenac 25 mg/mL on the surface of the cNF (T neurofibroma = treatment) or physiological saline (C neurofibroma = control) and reapplied twice daily for 3 days. Neurofibroma assessments included visual and dermatoscopy observations noting color and presence of necrosis, presence of flaccidity, measurements in two dimensions, photographs, and histopathology after excision. The primary efficacy variable was the presence of tissue necrosis. The primary safety variable was the occurrence of treatment-related adverse events. RESULTS: Six patients were included in the study. The treatment resulted in transitory topical changes (healing of the microporation grid with formation of scintillating tissue layer, hyperemia and desquamation), with no statistically significant variation in the dimensions of the T and C neurofibromas in relation to pretreatment measurements. There was no necrosis in the T or C neurofibromas. In the histopathological analysis, there was no significant difference in the distribution of chronic (lymphocytic) inflammatory infiltrate in the papillary reticular dermis (subepithelial), type of infiltrate (diffuse, perivascular, or both), presence of fibrosis, and presence of atrophy among the T and C neurofibromas. No adverse events attributable to the use of diclofenac were reported during the treatment period. CONCLUSIONS: Treatment did not result in significant alterations in terms of presence of tissue necrosis, size, or histopathological features in the T neurofibromas or in comparison to the C neurofibromas. Topical diclofenac with laser microporation was well-tolerated, with no adverse events attributable to diclofenac reported. Whether these observations are due to minimal systemic and neurofibroma exposure remain to be explored in dosage studies with larger patient groups. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03090971) retrospectively registered March 27, 2017.
RESUMO
OBJECTIVE: To produce a historical account of rehabilitation actions in the context of the Brazilian Unified Health Care System (SUS). METHODS: Search of SciELO, LILACS, and MEDLINE databases for literature published between 1980 and 2009. The following Portuguese search terms were used: Sistema Unico de Saúde, reabilitação, políticas de saúde, assistência médica, história. The English terms "rehabilitation" and "public health" were also used. Federal laws and Ministry of Health manuals available at the city of Rio de Janeiro Coordinating Office for Rehabilitation Programs, Fundação Instituto Oswaldo Cruz library, and in BIREME database were also surveyed. RESULTS: Only a small number of publications were recovered (four books, three Health Ministry manuals, four articles published in Brazil, one master's thesis, and one doctoral dissertation). Nevertheless, analysis of these materials revealed that since many municipalities are still incapable of ensuring the right to universal and comprehensive health care, rehabilitation actions are often carried out in a precarious manner, unsupported by an adequate and comprehensive policy. On the other hand, there have been real improvements in terms of expanding care to the population with special needs. CONCLUSIONS: There still are factors hindering the achievement of optimal results in the care to people with special needs. The challenge of action planning must be undertaken especially by municipal governments to ensure an adequate supply of services and thus equity of access and comprehensive health care.

OBJECTIVE: Duchenne muscular dystrophy, an X-linked genetic disease, leads to progressive muscle weakness mainly in the lower limbs. Motor function tests help to monitor disease progression. Can low-cost, simple assessments help in the diagnostic suspicion of Duchenne muscular dystrophy? The authors aim to define the sensitivity of time to rise from the floor, time to walk 10meters, and time to run 10meters, evaluating them as eventual diagnostic screening tools. METHODS: This is an analytical, observational, retrospective (1998-2015), and prospective study (2015-2018). Cases were recruited from the database of the pediatric neurology department and the healthy, from child care consultations, with normal gait development (up to 15 months) and without other comorbidities (neuromuscular, pulmonary, heart diseases) from the same university hospital. RESULTS: 128 Duchenne muscular dystrophy patients and 344 healthy children were analyzed, equally distributed in age groups. In Duchenne muscular dystrophy, there is a progressive increase in the means of the times to perform the motor tests according to the age group, which accelerates very abruptly after 7 years of age. Healthy children acquire maximum motor capacity at 6 years and stabilize their times. The time to rise showed a p-value <0.05 and a strong association (effect size [ES] >0.8) in all age groups (except at 12 years), with time to walk 10 meters from 9 years, and with time to run 10 meters , from 5 years. The 100% sensitivity points were defined as follows: time to rise, at 2s; time to walk 10 meters, 5s; time to run 10 meters, 4s. CONCLUSIONS: Time to rise is a useful and simple tool in the screening of neuromuscular disorders such as Duchenne muscular dystrophy, a previously incurable disease with new perspectives for treatment.

PURPOSE: To describe the incidence and risk factors of communication, swallowing, and orofacial myofunctional disorders in a cohort of children and adolescents with cancer and benign neoplasms. METHODS: A prospective cohort study conducted with children aged ⩾ 2 years and adolescents of both genders admitted at the Pediatric Oncology Department of the Instituto Nacional de Câncer (INCA) between March 2014 and April 2015. Study participants were submitted to a Speech-Language Pathology (SLP) assessment at three different times: (T1) at hospital admission; (T2) six months after admission; (T3) one year after admission. RESULTS: One hundred and sixty individuals were evaluated. At the time of hospital admission, 68 individuals (42.5%) presented with some type of SLP disorder. After one year of follow-up, 22.8% of the patients had developed new impairments. The occurrence of new speech-language disorders had a statistically significant association with the tumor site. In the risk analysis for the development of speech-language disorders with respect to the primary tumor site, compared to other sites, the central nervous system (CNS) tumor group was 8.29 times more likely to present some new alterations, while the head and neck (HN) tumor group had a 10.36-fold higher risk. CONCLUSION: An incidence of 22.8% for communication, swallowing, and orofacial myofunctional disorders was observed. The development of these disorders was greater in individuals with tumors in the CNS and in the HN region.

PURPOSE: To compare the performance in phonological processing skills, reading speed and reading comprehension before and after phonological remediation in a restricted group of schoolchildren with Attention Deficit Hyperactivity Disorder (ADHD) and with dyslexia. METHODS: Thirty-two schoolchildren from the 2nd to 8th year of Elementary School of both genders, with diagnosis of ADHD and Dyslexia according to the DSM-5, participated in this study. All patients underwent Phonological Remediation Program consisted of 18 weekly sessions. RESULTS: The results, expressed in z scores, showed a statistically significant difference between before and after remediation assessments in phonological processing skills, such as syllabic and phonemic awareness, working memory and lexical access. Rhyming task was analyzed separately because it represents another level of segmentation and, for this result, there was no significance. Besides these results, there was a statistically significant difference in reading speed and reading comprehension. CONCLUSION: The phonological remediation program contributes to the development of phonological processing, reading speed and reading comprehension in this population.
OBJETIVO: Comparar o desempenho da avaliação do processamento fonológico, velocidade de leitura e compreensão de texto antes e depois da aplicação de um programa de remediação fonológica em um grupo restrito de escolares com Transtorno do Déficit de Atenção e Hiperatividade (TDAH) e dislexia. MÉTODOS: Participaram deste estudo 32 escolares do 2º ao 8º ano do Ensino Fundamental, de ambos os sexos, com diagnóstico de TDAH e dislexia de acordo com o DSM-5, atendidos no Ambulatório de Neurologia Infantil do IPPMG/UFRJ. Todos os pacientes foram submetidos ao programa de remediação fonológica, que consistiu em 18 sessões semanais. RESULTADOS: Os resultados, expressos em escore z, indicaram diferença estatisticamente significativa entre as avaliações pré e pós-remediação nas habilidades do processamento fonológico, como em consciência silábica e fonêmica, memória de trabalho e acesso lexical. A tarefa de rima foi analisada separadamente, pois é considerada uma tarefa com nível de segmentação distinto de outros níveis silábicos e, para este resultado não houve significância. Além desses, houve diferença estatisticamente significativa também nos testes que medem velocidade de leitura e compreensão de texto. CONCLUSÃO: O programa de remediação fonológica contribui para o desenvolvimento do processamento fonológico, leitura e compreensão textual nesta população.

INTRODUCTION: Oral mycobiome profiling is important to understand host-pathogen interactions that occur in various diseases. Invasive fungal infections are particularly relevant for patients who have received chemotherapy and for those who have HIV infection. In addition, changes in fungal microbiota are associated with the worsening of chronic conditions like atopic dermatitis (AD). This work aims, through a systematic review, to analyze the methods used in previous studies to identify oral fungi and their most frequent species in patients with the following conditions: HIV infection, leukemia, and atopic dermatitis. METHODS: A literature search was performed on several different databases. Inclusion criteria were: written in English or Portuguese; published between September 2009 and September 2019; analyzed oral fungi of HIV-infected, leukemia, or AD patients. RESULTS: 21 studies were included and the most identified species was Candida. The predominant methods of identification were morphological (13/21) and sugar fermentation and assimilation tests (11/21). Polymerase chain reaction (PCR) was the most used molecular method (8/21) followed by sequencing techniques (3/21). CONCLUSIONS: Although morphological and biochemical tests are still used, they are associated with high-throughput sequencing techniques, due to their accuracy and time saving for profiling the predominant species in oral mycobiome.
