RESUMO

Introducción: la teleconsulta es una herramienta asistencial útil en el manejo multidisciplinar de pacientes con indicación de nutrición enteral domiciliaria (NED). El empleo de diferentes herramientas de teleconsulta de NED, como ocurre en el Sistema Andaluz de Salud (SAS), conlleva heterogeneidad en los procesos de derivación entre los servicios de Atención Primaria (AP) y hospitalaria en una misma región. Objetivos: consensuar perfiles de pacientes y conjunto de datos mínimos necesarios para garantizar una derivación adecuada a la teleconsulta de NED, independientemente de la herramienta existente. Estos aspectos consensuados en Andalucía pueden servir de referencia en otras regiones. Métodos: se siguieron tres pasos consecutivos: a) revisión no sistemática de la literatura indexada sobre la teleconsulta en nutrición clínica en España; b) encuesta para conocer la implementación y las necesidades no satisfechas de las herramientas de teleconsulta en los hospitales públicos andaluces; y c) reuniones de trabajo y consenso de 14 profesionales sanitarios de AP (n = 4) y endocrinología y nutrición clínica hospitalaria (n = 10). Resultados: se consensuaron tres formularios de derivación en los que se definieron tres perfiles de pacientes, con el correspondiente conjunto mínimo de datos necesario para solicitar la teleconsulta de NED. El equipo de AP debe proporcionar este conjunto mínimo de datos al especialista en nutrición clínica a través de una herramienta de teleconsulta, implementada en el SAS. Conclusiones: tres formularios consensuados entre profesionales sanitarios involucrados en el proceso de derivación sirven para estandarizar la solicitud de teleconsulta de NED entre equipos asistenciales en función de perfiles de pacientes.(AU)


Introduction: teleconsultation is a useful healthcare tool in the multidisciplinary management of patients with indications of home enteral nutrition (HEN). The use of different teleconsultation platforms, as it happens in the Andalusian Health System (SAS), results in heterogeneous referral processes between Primary Care and hospital services in the same region. Objectives: to establish a consensus on patient profiles and the minimum data set necessary to guarantee an adequate referral to NED teleconsultation regardless of the existing platform. These agreed aspects in Andalusia can serve as a reference in other regions. Methods: three consecutive steps were followed: a) non-systematic review of the indexed literature on teleconsultation in clinical nutrition in Spain; b) survey to know the implementation and unmet needs of teleconsultation platforms in Andalusian public hospitals; and c) working meetings and consensus of 14 health professionals of Primary Care (n = 4) and endocrinology and hospital clinical nutrition (n = 10). Results: three referral forms were agreed in which three patient profiles were defined, with the corresponding minimum set of data necessary to request NED teleconsultation. The Primary Care team should provide this set of data to the clinical nutrition specialist via a teleconsultation platform, implemented in the SAS. Conclusions: three agreed forms between healthcare professionals involved in the referral process serve to standardize the request for teleconsultation of NED between healthcare teams based on patient profiles.(AU)

RESUMO

Introduction: Bioelectrical impedance analysis (BIA) serves as a method to estimate body composition. Parameters such as phase angle (PA), standardized phase angle (SPA), body mass cell (BCM), BCM index (BCMI), and fat-free mass (FFM) might significantly impact the prognosis of head and neck cancer (HNC) patients. The present study aimed to investigate whether bioelectrical parameters can be used to predict survival in the HNC population and establish the optimal cutoff points for predictive accuracy. Methods: A multicenter observational study was performed across 12 tertiary hospitals in Andalusia (a region from the south of Spain). A total of 494 patients diagnosed with HNC between 2020 and 2022 at different stages were included in this study, with a minimum follow-up period of 12 months. The BIA assessment was carried out during the first 2 weeks of radical radiotherapy treatment with chemotherapy or other systemic treatments. A multivariate logistic regression analysis of overall survival, complications, hospital admission, and palliative care and its relationship with BIA nutritional assessment was performed. Results: Significant prognostic factors identified in the multivariable analysis encompassed phase angle (PA), standardized phase angle (SPA), body cell mass (BCM), and BCM index (BCMI). Lower PA and BCM values were significantly associated with adverse clinical outcomes. A BCM threshold above 17 kg/m2 was the most significant predictor for predicting survival within the overall HNC population. The PA values of <5.1° in male and <4.8° in female patients showed the best predictive potential for mortality. Increased PA (as a continuous variable) demonstrated a significantly reduced risk for mortality (OR, 0.64; 95% CI, 0.43-0.94; p < 0.05) and a decreased likelihood of hospital admission (OR, 0.75; 95% CI, 0.52-1.07; p < 0.05). Higher BCM correlated with a lower risk of mortality (OR, 0.88; 95% CI, 0.80-0.96; p < 0.01) and a diminished probability of hospital admission (OR, 0.91; 95% CI, 0.83-0.99; p < 0.05). Conclusion: BIA is a crucial tool in the nutritional assessment of HNC patients. BCM and PA are the main bioelectrical parameters used to predict clinical outcomes in this population. Future studies are needed to validate BIA variables in a large cohort to ensure whether early intensification of nutritional treatment would improve survival.

RESUMO

Nephrotic syndrome (NS) is a key clinical entity for the internist to recognize and understand. A wide range of infectious, metabolic, malignant, and autoimmune processes drive nephrosis, leading to a syndrome defined by proteinuria, edema, and hypoalbuminemia. NS occurs due to increased permeability to proteins at the level of the glomerulus, which allows for passage of albumin and other proteins into the urine. Proteinuria leads to a cascade of clinical complications characterized by fluid accumulation, kidney inflammation, and dysregulation of coagulation and immunity. In this article, the authors review the clinically important etiologies of NS that should inform an initial clinical evaluation.

RESUMO

Myelofibrosis (MF) is a myeloproliferative neoplasm (MPN) with heterogeneous clinical course. Allogeneic hematopoietic cell transplantation remains the only curative therapy, but its morbidity and mortality require careful candidate selection. Therefore, accurate disease risk prognostication is critical for treatment decision-making. We obtained registry data from patients diagnosed with MF in 60 Spanish institutions (N = 1386). These were randomly divided into a training set (80%) and a test set (20%). A machine learning (ML) technique (random forest) was used to model overall survival (OS) and leukemia-free survival (LFS) in the training set, and the results were validated in the test set. We derived the AIPSS-MF (Artificial Intelligence Prognostic Scoring System for Myelofibrosis) model, which was based on 8 clinical variables at diagnosis and achieved high accuracy in predicting OS (training set c-index, 0.750; test set c-index, 0.744) and LFS (training set c-index, 0.697; test set c-index, 0.703). No improvement was obtained with the inclusion of MPN driver mutations in the model. We were unable to adequately assess the potential benefit of including adverse cytogenetics or high-risk mutations due to the lack of these data in many patients. AIPSS-MF was superior to the IPSS regardless of MF subtype and age range and outperformed the MYSEC-PM in patients with secondary MF. In conclusion, we have developed a prediction model based exclusively on clinical variables that provides individualized prognostic estimates in patients with primary and secondary MF. The use of AIPSS-MF in combination with predictive models that incorporate genetic information may improve disease risk stratification.

RESUMO

Lipodystrophy syndromes are rare diseases that could be of genetic or acquired origin. The main complication of lipodystrophy is the dysfunction of adipose tissue, which leads to an ectopic accumulation of triglycerides in tissues such as the liver, pancreas and skeletal muscle. This abnormal fat distribution is associated with hypertriglyceridemia, insulin resistance, liver steatosis, cardiomyopathies and chronic inflammation. Although the origin of acquired lipodystrophies remains unclear, patients show alterations in genes related to genetic lipodystrophy, suggesting that this disease could be improved or aggravated by orchestrating gene activity, for example by diet. Nowadays, the main reason for adipose tissue dysfunction is an imbalance in metabolism, caused in other pathologies associated with adipose tissue dysfunction by high-fat diets. However, not all dietary fats have the same health implications. Therefore, this article aims to summarize the main genes involved in the pathophysiology of lipodystrophy, identify connections between them and provide a systematic review of studies published between January 2017 and January 2022 of the dietary fats that can modulate the development of lipodystrophy through transcriptional regulation or the regulation of protein expression in adipocytes.

RESUMO

Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis comprises a rare entity of disorders that affects primarily small and medium-sized blood vessels. Since first documented in 1897, we have come a long way trying to understand the pathogenesis and finding an optimal treatment regimen. The pathogenesis of ANCA vasculitis is not well understood and despite many advances in treatment, the morbidity and mortality remains high. Over the last decade, there have been many advancements toward elucidating the pathogenesis, optimizing current therapies, and discovering new medicines. Presently, one trend is aimed at minimizing the adverse effects of glucocorticoids by reducing their use without sacrificing efficacy and safety. A new medicine targeting the alternative complement system has emerged and intends to replace glucocorticoids. Here, we review three articles that describe these new trends in the management of ANCA vasculitis.

RESUMO

Introducción: Los trastornos de la voz pueden afectar negativamente a la autoestima del niño y suponer un problema para su socialización. El Pediatric Voice Handicap Index (P-VHI) es un cuestionario de calidad de vida adaptado para su aplicación en niños que estudia la repercusión de la disfonía en los ámbitos funcional, físico y emocional. Métodos: Estudio retrospectivo, observacional y analítico sobre 87 pacientes con edades comprendidas entre los cinco y 14 años con diagnóstico de disfonía. El grupo control consta de 31 pacientes del mismo rango de edad en los que se descartó la presencia de patología a nivel otorrinolaringológico. Se revisan los datos de edad, sexo, entorno familiar y práctica de deporte de ambos grupos y se analiza su relación con la presencia de disfonía. Se estudia el impacto de la disfonía sobre la calidad de vida de los niños mediante el cuestionario P-VHI. Resultado: Encontramos una relación estadísticamente significativa entre la presencia de disfonía y el sexo masculino (65.5% en el grupo con disfonía vs. 29% en el grupo control), tener hermanos (89.7 vs. 71%) y tener historia familiar de alteraciones de la voz (33.3 vs. 3.2%). En el cuestionario P-VHI para todas las categorías se obtuvo una puntuación significativamente mayor en el grupo con disfonía respecto al grupo control. Conclusiones: La disfonía afecta negativamente al niño en las esferas física, emocional y social. Es conveniente una detección, diagnóstico y tratamiento temprano y proporcional al impacto que genera.(AU)


Introduction: Voice disorders can negatively affect the child's self-esteem and pose a problem for their socialization. The P-VHI (Pediatric Voice Handicap Index) is a quality of life questionnaire adapted for use in children that studies the impact of dysphonia on the functional, physical and emotional levels. Methods: Retrospective, observational and analytical study of a group of 87 patients aged between 5 and 14 years old with a diagnosis of dysphonia. The control group consisted of 31 patients same age range in whom was discarded the presence of otorhinolaryngological disease. We collected the data referred to age, sex, family environment and sport practice of both groups and analyzed their relationship with the presence of dysphonia. The impact of dysphonia on children's quality of life was studied using the Pediatric Voice Handicap Index (P-VHI) questionnaire. Results: We found a statistically significant relationship between the dysphonia and the male sex (65.5% in the group with dysphonia vs. 29% in the control group), having siblings (89.7% vs. 71%) and having a family history of voice disorders (33.3% vs. 3.2%). In the P-VHI questionnaire for all categories a significantly higher score was obtained in the group with dysphonia compared to the control group. Conclusión: Dysphonia negatively affects children in the physical, emotional and social spheres. It is convenient an early detection, diagnosis and treatment, proportional to the impact generated.(AU)

RESUMO

Available data have proved insufficient to develop consensus recommendations on the prevention of thrombosis and bleeding in myelofibrosis (MF). We evaluated the incidence and risk factors of vascular complications in 1613 patients from the Spanish Myelofibrosis Registry. Over a total of 6981 patient-years at risk, 6.4% of the study population had at least one thrombotic event after MF diagnosis, amounting to an incidence rate of 1.65 per 100 patient-years. Prior history of thrombosis, the JAK2 mutation, and the intermediate-2/high-risk International Prognostic Scoring System (IPSS) categories conferred an increased thrombotic risk after adjustment for the risk-modifying effect of anti-thrombotic and cytoreductive treatments. History of thrombosis and the JAK2 mutation allowed us to pinpoint a group of patients at higher risk of early thrombosis. No decreased incidence of thrombosis was observed while patients were on anti-thrombotic or cytoreductive treatment. An increased risk of venous thrombosis was found during treatment with immunomodulatory agents. A total of 5.3% of patients had at least one episode of major bleeding, resulting in an incidence rate of 1.5 events per 100 patient-years. Patients in the intermediate-2/high-risk IPSS categories treated with anti-coagulants had an almost sevenfold increased risk of major bleeding. These findings should prove useful for guiding decision-making in clinical practice.

RESUMO

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has rapidly spread worldwide and claimed millions of lives. Several studies have attempted to understand the relationship between COVID-19 infection and health disparities. The aim of the current work was to evaluate the pre-admission health characteristics, symptomatology, diagnostic abnormalities, treatment measures and clinical outcomes of the community served by our institution, with a sub-analysis of our Hispanic community. Methods: This is a single-center, cross-sectional cohort study of patients with COVID-19 admitted from 15 March 2020 to 30 April 2020 to MacNeal Hospital. A retrospective chart review was performed including patients >18 years and a positive nasopharyngeal SARS-CoV-2 PCR. Demographical data, comorbidities, clinical data, treatment regimen, and patient outcomes were collected. Results: A total of 257 patients were included in the study of which 60.4% were identified as Hispanic. The median age at admission of Hispanic patients was significantly lower compared to non-Hispanic patients (56.6 vs. 65.7 years, p<0.01). Non-Hispanic patients had lower prevalence of hypertension, coronary artery disease, and chronic lung disease. Most common at presentation were shortness of breath (69.6%), cough (69.2%), and fever (64%). Hypertension was the most common comorbidity (53.6%). Approximately 89% of the patients received antibiotics, 40.4% hydroxy-chloroquine, 13.2% steroids, and 6% tocilizumab. Twenty six percent required mechanical ventilation (MV), and over half of them (56.7%) were Hispanic. The strongest factors associated with MV were smoking (OR 2.97, 95%CI 1.01-8.69), CRP >10 mg/dL (OR 4.53, 95%CI 1.49-13.38) and D-dimer >1.5 mcg/mL (OR 3.63, 95%CI 1.31-10.05). An oxygen saturation of >90% on room air on presentation was a protective factor when predicting intubation (OR 0.11, 95%CI 0.03-0.33). The overall 30-day mortality rate was 17.1% (n=44); 11.9% in the Hispanic group vs 26.3% in the non-Hispanic group (p<0.003). Conclusions: Our review of consecutive patients admitted with COVID-19 demonstrated that over half of patients were of Hispanic descent. Interestingly enough, despite being significantly younger and healthier, the need for mechanical ventilation in the Hispanic group was not significantly different compared to the non-Hispanic group. However, the Hispanic group had a lower mortality rate.

RESUMO

This retrospective study evaluated 66 patients diagnosed with relapsed and/or refractory mantle cell lymphoma (R/R MCL) treated with ibrutinib in Spain in routine clinical practice. At diagnosis, patients had a median age of 64.5 years, 63.6% presented with intermediate/high sMIPI (simplified prognostic index for advanced-stage mantle cell lymphoma), 24.5% had the blastoid variant, and 55.6% had a Ki67 > 30%. Patients had received a median of 2 prior lines of therapy (range 1-2; min-max 1-7). Overall response rate was 63.5%, with 38.1% of patients achieving complete response (CR). With a median duration of ibrutinib exposure of 10.7 months (range 5.2-19.6; min-max 0.3-36), the median progression-free survival (PFS) and overall survival (OS) were 20 months [95% confidence interval (CI) 8.8-31.1] and 32 months (95% CI 22.6-41.3), respectively, and were not reached in patients achieving CR. No grade ≥ 3 cardiovascular toxicity or bleeding was reported. This study supports that treatment with ibrutinib leads to high response rates and favorable survival outcomes in patients with R/R MCL.

RESUMO

BRCA2 is essential for homologous recombination DNA repair. BRCA2 mutations lead to genome instability and increased risk of breast and ovarian cancer. Similarly, mutations in BRCA2-interacting proteins are also known to modulate sensitivity to DNA damage agents and are established cancer risk factors. Here we identify the tumor suppressor CDK5RAP3 as a novel BRCA2 helical domain-interacting protein. CDK5RAP3 depletion induced DNA damage resistance, homologous recombination and single-strand annealing upregulation, and reduced spontaneous and DNA damage-induced genomic instability, suggesting that CDK5RAP3 negatively regulates double-strand break repair in the S-phase. Consistent with this cellular phenotype, analysis of transcriptomic data revealed an association between low CDK5RAP3 tumor expression and poor survival of breast cancer patients. Finally, we identified common genetic variations in the CDK5RAP3 locus as potentially associated with breast and ovarian cancer risk in BRCA1 and BRCA2 mutation carriers. Our results uncover CDK5RAP3 as a critical player in DNA repair and breast cancer outcomes.

RESUMO

Corticosteroid-binding globulin (CBG) is the main transport protein for cortisol, binding up to 90% in a 1:1 ratio. CBG provides transport of cortisol within the circulation and targeted cortisol tissue delivery. Here, we describe the clinically novel "CBG Montevideo" a SERPINA6 pathogenic variant that results in a 50% reduction in plasma CBG levels. This was associated with low serum total cortisol and clinical features of hypoglycemia, exercise intolerance, chronic fatigue, and hypotension in the proband, a 7-year-old boy, and his affected mother. Previous reports of 9 human CBG genetic variants affecting either CBG concentrations or reduced CBG-cortisol binding properties have outlined symptoms consistent with attenuated features of hypocortisolism, fatigue, and hypotension. Here, however, the presence of hypoglycemia, despite normal circulating free cortisol, suggests a specific role for CBG in effecting glucocorticoid function, perhaps involving cortisol-mediated hepatic glucose homeostasis and cortisol-brain communication.

RESUMO

Fanconi anemia (FA) is characterized by chromosome fragility, bone marrow failure (BMF) and predisposition to cancer. As reverse genetic mosaicism has been described as "natural gene therapy" in patients with FA, we sought to evaluate the clinical course of a cohort of FA mosaic patients followed at referral centers in Spain over a 30-year period. This cohort includes patients with a majority of T cells without chromosomal aberrations in the DEB-chromosomal breakage test. Relative to non-mosaic FA patients, we observed a higher proportion of adult patients in the cohort of mosaics, with a later age of hematologic onset and a milder evolution of (BMF). Consequently, the requirement for hematopoietic stem cell transplant (HSCT) was also lower. Additional studies allowed us to identify a sub-cohort of mosaic FA patients in whom the reversion was present in bone marrow (BM) progenitor cells leading to multilineage mosaicism. These multilineage mosaic patients are older, have a lower percentage of aberrant cells, have more stable hematology and none of them developed leukemia or myelodysplastic syndrome when compared to non-mosaics. In conclusion, our data indicate that reverse mosaicism is a good prognostic factor in FA and is associated with more favorable long-term clinical outcomes.

RESUMO

Fanconi anemia (FA) patients have an exacerbated risk of head and neck squamous cell carcinoma (HNSCC). Treatment is challenging as FA patients display enhanced toxicity to standard treatments, including radio/chemotherapy. Therefore, better therapies as well as new disease models are urgently needed. We have used CRISPR/Cas9 editing tools in order to interrupt the human FANCA gene by the generation of insertions/deletions (indels) in exon 4 in two cancer cell lines from sporadic HNSCC having no mutation in FA-genes: CAL27 and CAL33 cells. Our approach allowed efficient editing, subsequent purification of single-cell clones, and Sanger sequencing validation at the edited locus. Clones having frameshift indels in homozygosis did not express FANCA protein and were selected for further analysis. When compared with parental CAL27 and CAL33, FANCA-mutant cell clones displayed a FA-phenotype as they (i) are highly sensitive to DNA interstrand crosslink (ICL) agents such as mitomycin C (MMC) or cisplatin, (ii) do not monoubiquitinate FANCD2 upon MMC treatment and therefore (iii) do not form FANCD2 nuclear foci, and (iv) they display increased chromosome fragility and G2 arrest after diepoxybutane (DEB) treatment. These FANCA-mutant clones display similar growth rates as their parental cells. Interestingly, mutant cells acquire phenotypes associated with more aggressive disease, such as increased migration in wound healing assays. Therefore, CAL27 and CAL33 cells with FANCA mutations are phenocopies of FA-HNSCC cells.

RESUMO

Dopamine receptor 2 agonists (D2-ags) have been shown to reduce the size of tumors by targeting aberrant angiogenesis in pathological tissue. Because of this, the use of a D2-ag was inferred for endometriosis treatment. When assayed in mouse models however, D2-ags have been shown to cause a shift of the immature vessels towards a more mature phenotype but not a significant reduction in the amount of vascularization and size of lesions. These has raised concerns on whether the antiangiogenic effects of these compounds confer a therapeutic value for endometriosis. In the belief that antiangiogenic effects of D2-ags in endometriosis were masked due to non-optimal timing of pharmacological interventions, herein we aimed to reassess the antiangiogenic therapeutic potential of D2-ags in vivo by administering compounds at a timeframe in which vessels in the lesions are expected to be more sensitive to antiangiogenic stimuli. To prove our point, immunodeficient (NU/NU) mice were given a D2-ag (cabergoline), anti-VEGF (CBO-P11) or vehicle (saline) compounds (n = 8 per group) starting 5 days after implantation of a fluorescently labeled human lesion. The effects on the size of the implants was estimated by monitoring the extent of fluorescence emitted by the lesion during the three-week treatment period. Subsequently mice were sacrificed and lesions excised and fixed for quantitative immunohistochemical/immunofluorescent analysis of angiogenic parameters. Lesion size, vascular density and innervation were comparable in D2-ag and anti-VEGF groups and significantly decreased when compared to control. These data suggest that D2-ags are as powerful as standard antiangiogenic compounds in interfering with angiogenesis and lesion size. Our preliminary study opens the way to further exploration of the mechanisms beneath the antiangiogenic effects of D2-ags for endometriosis treatment in humans.

RESUMO

INTRODUCCIÓN: La prevalencia de la disfonía en la edad pediátrica se estima en torno a un 6%. La disfonía en este grupo de edad suele deberse a un uso incorrecto de la voz, que lleva al desarrollo de lesiones en las cuerdas vocales. Esta alteración puede afectar negativamente a la autoestima del niño. El objetivo del estudio es describir la epidemiología de los trastornos de la voz en la edad pediátrica en nuestra área, realizar un examen detallado de la voz, así como identificar el impacto de esta afección sobre la calidad de vida. MATERIAL Y MÉTODO: Presentamos un estudio descriptivo sobre 87 pacientes diagnosticados de disfonía con edades comprendidas entre los 5 y los 14 años. La recogida de datos se realizó en nuestro centro entre enero del año 2016 y abril del 2019. Analizamos factores epidemiológicos y clínicos. Se estudia el impacto en la calidad de vida mediante el cuestionario Pediatric Voice Handicap Index. RESULTADOS: Se incluyen 87 pacientes, 57 varones (65,5%) y 30 mujeres (34,5%). La edad media fue de 8,5 años (DE 2,08; rango 4-13). Los parámetros más constantes fueron tener un hermano o más (89,6%) y la práctica de deporte en equipo (58,6%). La alteración fonatoria más frecuente fue la tensión muscular global (88,5%). En el examen laringoscópico, el hallazgo más frecuente fue la presencia de nódulos vocales (45,9%). La puntuación media en el Pediatric Voice Handicap Index fue de 24,3 puntos en total: 4,9 en la escala funcional, 17,6 en la física y 1,8 en la emocional. CONCLUSIONES: Es fundamental una correcta anamnesis que incluya datos sobre el entorno familiar o la práctica de deporte en equipo. La exploración física debe incluir el examen laringoscópico. Existe un impacto en la calidad de vida de los pacientes con disfonía, percibido por ellos y por sus familiares, siendo el físico el principal componente percibido como afectado. Consideramos necesario el abordaje multidisciplinar de esta afección


INTRODUCTION: The prevalence of dysphonia in children is estimated at around 6%. Dysphonia in this age group is usually due to misuse of the voice that leads to the development of vocal fold injuries. This condition can negatively affect the child's self-esteem. The aim of the study is to describe the epidemiology of voice disorders in children in our area, perform an examination of the voice, as well as identify the impact of this pathology on quality of life. MATERIAL AND METHOD: We present a descriptive study with 87 patients aged between 5 and 14 years old, diagnosed with dysphonia. Data collection was carried out in our centre between January 2016 and April 2019. We analysed epidemiological and clinical factors. The impact on quality of life was studied using the Pediatric Voice Handicap Index questionnaire. RESULTS: 87 patients, 57 men (65.5%) and 30 women (34.5%) were included. Mean age 8.5 years (SD: 2.08; range 4-13). The most frequent phonatory disturbance was global muscle tension (88.5%). In the laryngoscopic examination, the most frequent finding was the presence of vocal nodules (45.9%). The average score on the Pediatric Voice Handicap Index was 24.3 points in total; 4.9 on the functional scale; 17.6 on the physical scale and 1.8 on the emotional scale. CONCLUSION: A correct anamnesis that includes the family environment and practice of team sport is essential. The physical examination should include a laryngoscopic examination. There is an impact on the quality of life of patients with dysphonia perceived by them and their families; the physical component is perceived to be most affected. We consider a multidisciplinary approach to this condition necessary
