RESUMO

Abstract Objectives This study aims to evaluate the characteristics and treatment response of patients with pityriasis lichenoides seen in the last 43 years in a pediatric dermatology service. Methods This was a retrospective, analytical, longitudinal study of patients under 15 years of age. The medical records were reviewed and data were presented as frequencies, means and variances. Student's t-test, Mann-Whitney test, Fisher's exact test, Pearson/Yates chi-square test and multivariate logistic regression model were used, with p < 0.05 considered. Results 41 patients were included, 32 (78.0%) with pityriasis lichenoides chronica (PLC), five (12.2%) with pityriasis lichenoides et varioliformis acuta (PLEVA) and four (9.8%) with clinical PLC without biopsy. The age range of school children and adolescents was 19 (46.3%) and 13 (31.7%) respectively and 27 (65.8%) were male. Two peaks of the highest frequency were observed between 2004 and 2006 (10 patients - 24.4%) and another between 2019 and 2021 (6 patients - 14.7%). There was remission in 71.9% (n = 23), with 56.6% (n = 17) of those who used antibiotic therapy and 80% (n = 4) of those who had phototherapy. The chance of remission was 13 times greater in patients with disease onset after 5 years of age. Conclusions The clinical form most commonly found was PLC mainly in school children and adolescents. The frequency peaks coincided with infectious outbreaks. The remission rate was satisfactory with antibiotic therapy, but higher with phototherapy. Remission was greater in patients with disease onset after 5 years of age.

RESUMO

Background: Actinic keratosis (AK) is a highly prevalent pre-cancerous skin lesion that often leads to cutaneous squamous cell carcinoma. There are different stages of evolution of the disease and several features that characterize keratosis. This study aimed to develop a qualitative and quantitative visual diagnostic tool to facilitate the identification of the characteristics and severity of the main cellular attributes of AK and to show its applicability in evaluating the evolution or treatment through image analysis. Methods: Literature research on the main scientific databases and in the institute's database was carried out to gather all the different levels of cellular transformation. To validate the scale, a preliminary characterization study was carried out with 21 subjects who had clinically diagnosed AK lesions to classify the attributes in each skin layer and test the accuracy of the diagnosis of the scale. Afterward, and to show the possibility of a follow-up with a topical treatment, the subjects were divided into two treatment groups, receiving either a cream formulation containing retinoic acid, or a placebo formula. The evaluation was carried out through confocal reflectance microscopy and a digital camera with dermoscopic quality before and after 90 days of treatment. Results: A table detailing the 18 attributes of AK, and a photographic scale containing RCM images graded by scores established for each characteristic and the frequency of spreading were developed. The results of the validation presented good repeatability, correlation with clinical evaluation, and capacity for differentiating treatments demonstrated by the significant improvement after topical treatment by the reduction of the score for 10 out of the 18 attributes. The preliminary study, evaluated by the detailed transformation scale highlights important differences in the subclinical approach that allows a deeper evaluation of the aspects of the lesion's re-incidence even after fully treated skin sites. Conclusion: This study brings an innovative method based on RCM, to assist in the quantification of cell transformation level, provide early diagnosis, and deliver a powerful treatment evaluation tool to provide smoother treatment, as well as prevent re-incidence in the cases.

RESUMO

RESUMEN La hiperostosis cortical infantil (HIC) o enfermedad de Caffey es un trastorno óseo autolimitado que se caracteriza por fiebre, irritabilidad, inflamación de los tejidos blandos y engrosamiento cortical de uno o más huesos. Es más común en el primer semestre de vida. Se informa el caso de un lactante de 3 meses con las características clínico-radiográficas propias de la enfermedad y los hallazgos de laboratorio más comunes que permitieron un acertado diagnóstico y seguir una conducta adecuada. El cuadro agudo se mantuvo durante pocos días y se observó resolución total del edema en cuatro semanas. El reconocimiento de esta rara infección evitará adoptar métodos diagnósticos y terapéuticos invasivos para el paciente.

ABSTRACT Infantile cortical hyperostosis (ICH) or Caffey disease is a self-limiting bone disorder characterized by fever, irritability, soft tissue swelling and cortical bone thickening. It is more common in infants < 6 months of age. We report the case of a 3-month-old infant with the clinical and radiographic characteristics of the disease and the most common laboratory findings which enabled an accurate diagnosis and appropriate management. The acute episode persisted for several days, followed by a complete resolution of the edema within four weeks. Identifying this rare infection will help avoid invasive diagnostic and therapeutic strategies.

RESUMO

Introducción: La hiponatremia se encuentra asociada aproximadamente con el 10% de los pacientes con traumatismo craneoencefálico, su baja frecuencia y la intuición clínica de esta relación la hace importante en el presente informe de caso. Objetivo: Describir la asociación de la hiponatremia con el traumatismo craneoen-cefálico con la finalidad de mejorar la comprensión de esta relación en el personal de salud y promover la implementación de estrategias de diagnóstico y manejo más efectivas basadas en predicciones bioquímicas y anatómicas actualizadas. Presentación del caso: Paciente masculino, adulto joven, con antecedentes de dos traumatismos craneoencefálicos, con hiponatremia sérica severa y síntomas persistentes de mareo y cefalea, tratado con diuréticos de asa y cloruro de sodio vía oral, con mejoría posterior al vigésimo día de hospitalización. Discusión: Ciertas alteraciones neurológicas con manifestación clínica evidente, se presentan por bajos niveles de sodio sérico, o por causas anatómicas y fisioló-gicas diferentes. Se ha demostrado una relación causal con mecanismo fisiopato-lógico no bien descrito sobre la hiponatremia y el traumatismo craneoencefálico. Conclusión: Es crucial tener una vigilancia meticulosa en pacientes con hipona-tremia severa, aunque presenten pocos síntomas clínicos (considerando antece-dentes como el traumatismo craneoencefálico en la anamnesis inicial y de segui-miento) como en este caso. Además, se destaca la necesidad de investigar las vías metabólicas que podrían verse afectadas por traumatismos craneoencefálicos, y que podrían tener un impacto directo en los niveles de sodio en sangre.

Introduction: Hyponatremia is found to be associated with approximately 10% of patients with traumatic brain injury. Despite its low frequency, the clinical intuition regarding this relationship underscores its significance in this case report. Objective: Describe the association between hyponatremia and traumatic brain in-jury, aiming to enhance healthcare professionals' understanding of this correlation and to advocate for the implementation of more effective diagnostic and manage-ment strategies based on updated biochemical and anatomical predictions. Case Presentation: A young adult male patient with a history of two traumatic brain injuries, severe serum hyponatremia, and persistent symptoms of dizziness and headache, treated with loop diuretics and oral sodium chloride, exhibited improvement after twenty days of hospitalization. Discussion: Certain neurological alterations with evident clinical manifestation are characterized by low levels of serum sodium, possibly stemming from distinct ana-tomical and physiological causes. A causal relationship with a poorly described pathophysiological mechanism between hyponatremia and traumatic brain injury has been suggested. Conclusion: Meticulous monitoring is imperative for patients with severe hypona-tremia, even when clinical symptoms are minimal, as observed in this case. Fur-thermore, emphasis is placed on the need to investigate metabolic pathways that may be affected by traumatic brain injuries, potentially exerting a direct impact on blood sodium levels.

RESUMO

Objetivo: La enfermedad de Caffey o hiperostosis cor- tical infantil es una enfermedad rara que afecta uno o más huesos en los primeros meses de vida y debido a su baja inci- dencia está subdiagnosticada, y por tanto se aplican procedi- mientos invasivos innecesarios en su estudio y tratamiento. Se presenta un caso clínico atípico de enfermedad de Caffey en una paciente mayor de 1 año de edad y su resolución. Caso clínico: El servicio de Cirugía Maxilofacial del Hospital Provincial Pediátrico Eduardo Agramonte Piña de Camagüey, Cuba, atiende a una niña de 1 año y 10 meses que se encontraba hospitalizada por presentar una inflamación alarmante en la región facial y cervical precedida de un cua- dro febril y dificultad para alimentarse. Se indicaron los estu- dios apropiados, cuyos resultados, junto a las características clínicas, permitieron diagnosticar la enfermedad de Caffey. Aunque sea una enfermedad rara, es importante estudiarla para realizar un correcto análisis de cada caso y diferenciarla de otras enfermedades que requieren de conductas terapéuti- cas agresivas (AU)

Aim: Caffey's disease or infantile cortical hyperostosis is a rare disease that affects one or more bones in the first months of life and due to its low incidence, it is underdiag- nosed, and therefore unnecessary invasive procedures are applied in its study and treatment. An atypical clinical case of Caffey's disease in a patient older than 1 year and its reso- lution is presented. Case report: The Maxillofacial Surgery service of the Eduardo Agramonte Piña Provincial Pediatric Hospital in Camagüey, Cuba, takes the case of a 1 year and 10-month-old female patient who was hospitalized for an alarming inflam- mation in the facial and cervical region, preceded by a fever and difficulty to eat. The appropriate studies were indicated, which results, together with the clinical characteristics, al- lowed the diagnosis of Caffey's disease. Although it is a rare entity, it is important to study it to carry out a correct analysis of each case and differentiate it from other diseases that re- quire aggressive therapeutic behaviors (AU)

RESUMO

Background: Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine-metabolic disorder in women of reproductive age. Diagnosis is based on the evidence-based international guideline 2018 and the Rotterdam Consensus to classify PCOS phenotypes. This study aims to characterize the biodemographic, clinical, metabolic, and reproductive variables and their relationship with PCOS phenotypes in a population from the Ecuadorian Andes. Methodology: A cross-sectional study was conducted with a non-random consecutive sample of 92 women who attended the outpatient gynecology and endocrinology clinic at the Hospital of the Technical University of Loja (UTPL)-Santa Inés, Loja, Ecuador, between January 2022 and July 2023. Descriptive statistics, mean calculations, standard deviation, parametric and nonparametric tests, odds ratios (OR), confidence intervals (CI), and p-values were employed. Results: The average age was 22 ± 3.4 years, with a predominantly mestizo, urban, single, highly educated, and medium-high socioeconomic level population. It was identified that phenotypes A + B are at a higher risk of developing oligomenorrhea and hypertriglyceridemia compared to phenotypes C + D, with statistically significant differences (p < 0.05). Furthermore, in terms of reproductive variables, phenotypes A + B exhibit a significantly higher frequency of elevated anti-Müllerian hormone (AMH) compared to phenotypes C + D, also with statistical significance (p < 0.05). Conclusions: The classical phenotypes A and B of PCOS are the most common in Ecuadorian Andean women and carry a higher risk of insulin resistance, anovulation, metabolic disorders, and elevated triglyceride levels compared to phenotypes C and D. Ethnic diversity and sociocultural habits influence the prevalence and clinical manifestations of these phenotypes.

RESUMO

To compare different criteria for the diagnosis of periodontitis and to evaluate the association of this condition with prematurity, this case-control study was conducted on 283 mothers of infants, divided into two groups based on gestational age (cases: <37 weeks, controls: ≥37 weeks), with 71 cases and 212 controls. The periodontal evaluation included probing depth (PD), clinical attachment level (CAL), plaque index, and bleeding on probing (BOP). Participants were classified regarding periodontitis per 14 criteria based on different periodontal parameters. The criterion selected as the gold standard was the presence of at least four teeth with one or more sites with a PD ≥ 4 mm, CAL ≥ 3 mm, and BOP at the same site. The prevalence of periodontal disease ranged from 8.1% to 55.1%. Moreover, compared to the gold standard, the sensitivities of the other criteria were 100%, while specificity ranged from 50.4% to 96.4%. Periodontitis, defined by six of the selected criteria, was associated with prematurity after multivariate adjustment, with OR ranging from 1.85 to 2.69 and 95% CI from 1.01 to 5.56; one of them was the gold standard mentioned above. Measurements using the clinical parameters of PD, CAL, and bleeding at the same site (criteria 5, 6, 7, 8), CPI (criterion 10), and at least four teeth with a PD ≥ 4 mm and CAL ≥ 3 mm (criterion 11) to define periodontitis showed a statistically significant association (p < 0.05). Given this study's limitations, we can conclude that the diagnostic criteria for a periodontitis definition using a PD ≥ 4 mm and CAL ≥ 3 mm in two or more teeth, with BOP at the same site, seem stronger when detecting an association between periodontitis and prematurity.

RESUMO

Introducción. La resección segmentaria del intestino y su derivación temporal o definitiva es un procedimiento frecuente en la práctica quirúrgica, que implica la construcción de un estoma. La enfermedad que lleva a la cirugía, las condiciones clínicas del paciente y los aspectos técnicos en la construcción de la ostomía son puntos claves en la evolución posoperatoria. Métodos. Se realizó una revisión de la literatura identificando las complicaciones asociadas a la construcción de estomas, con el objetivo de ofrecer herramientas de tratamiento y toma de decisiones al personal médico involucrado en la atención de estos pacientes. Resultados. La cirugía de urgencia, la inmunosupresión, la obesidad y la técnica en la apertura del orificio en la pared abdominal, favorecen la aparición de complicaciones tempranas que requieren manejo médico o reintervención quirúrgica. Conclusiones. Todo paciente con estoma debe ser valorado minuciosamente por el cirujano y la terapista enterostomal en las primeras 72 horas luego de la cirugía.

Introduction. Segmental resection of the intestine and its temporary or permanent bypass is a frequent procedure in surgical practice, which involves the construction of a stoma. The disease that leads to surgery, the clinical conditions of the patient and the technical aspects in the construction of the ostomy are key points in the postoperative evolution. Methods. A review of the literature was performed, identifying the complications associated with the construction of stomas, with the aim of offering treatment and decision-making tools to the medical personnel involved in the care of these patients. Results. Emergency surgery, immunosuppression, obesity, and the technique used to open the orifice in the abdominal wall favor the appearance of early complications that require medical management or surgical reintervention. Conclusions. Every patient with a stoma must be carefully evaluated by the surgeon and the enterostomal therapist in the first 72 hours after surgery.

RESUMO

Exhaled breath condensate (EBC) collection is a non-invasive sampling method that provides valuable information regarding the health status of the respiratory system by measuring inflammatory mediators, such as pH, hydrogen peroxide, and leukotriene B4. This scoping review aimed to provide an update on the collection and analysis of EBC in horses. A systematic search of three electronic databases, PubMed, Google Scholar, Science Direct, identified 40,978 articles, of which 1590 duplicates were excluded. Moreover, 39,388 articles were excluded because of irrelevance to this review, such as studies on other species, studies on respiratory exhalation, reviews, and theses. Finally, we evaluated 14 articles in this review. Our review revealed significant differences in the collection, storage, and processing of EBC samples, emphasizing the need for standardizing the technique and using specific equipment to improve the interpretation of the results.

RESUMO

BACKGROUND: The intersection of artificial intelligence (AI) with cancer research is increasing, and many of the advances have focused on the analysis of cancer images. OBJECTIVES: To describe and synthesize the literature on the diagnostic accuracy of AI in early imaging diagnosis of cervical cancer following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). SEARCH STRATEGY: Arksey and O'Malley methodology was used and PubMed, Scopus, and Google Scholar databases were searched using a combination of English and Spanish keywords. SELECTION CRITERIA: Identified titles and abstracts were screened to select original reports and cross-checked for overlap of cases. DATA COLLECTION AND ANALYSIS: A descriptive summary was organized by the AI algorithm used, total of images analyzed, data source, clinical comparison criteria, and diagnosis performance. MAIN RESULTS: We identified 32 studies published between 2009 and 2022. The primary sources of images were digital colposcopy, cervicography, and mobile devices. The machine learning/deep learning (DL) algorithms applied in the articles included support vector machine (SVM), random forest classifier, k-nearest neighbors, multilayer perceptron, C4.5, Naïve Bayes, AdaBoost, XGboots, conditional random fields, Bayes classifier, convolutional neural network (CNN; and variations), ResNet (several versions), YOLO+EfficientNetB0, and visual geometry group (VGG; several versions). SVM and DL methods (CNN, ResNet, VGG) showed the best diagnostic performances, with an accuracy of over 97%. CONCLUSION: We concluded that the use of AI for cervical cancer screening has increased over the years, and some results (mainly from DL) are very promising. However, further research is necessary to validate these findings.

Su frecuencia es cada vez más elevada en la población y existen varias patologías sistémicas y hábitos que empeoran su cuadro clínico. El objetivo de este trabajo fue determinar la frecuencia y características clínicas de pacientes con enfermedades periodontales que acuden a la cátedra de periodoncia en la Universidad Autónoma de Asunción en el período de 2011 al 2019. Estudio Observacional, descriptivo, retrospectivo, se procesaron 477 fichas clínicas de pacientes de la cátedra de Periodoncia de la Universidad Autónoma de Asunción desde el año 2011 al 2019. El tipo de muestreo utilizado fue no probabilístico por conveniencia. De las 477 fichas solo se analizaron 317 pacientes que cumplieron con los criterios de inclusión. Fueron el 56.46 % de sexo femenino y 43,53 % de sexo masculino, la mediana de edad fue de 33 (23-48) años. El 53% los pacientes presentaban periodontitis crónica y comorbilidades como diabetes e hipertensión arterial. Solo el 11,9 % fueron fumadores. En cuanto a los pacientes diabéticos la mayoría eran de sexo femenino y de edad avanzada, presentando como diagnóstico más frecuente la periodontitis crónica. El diagnóstico clínico más frecuente de la población estudiada fue la periodontitis crónica, seguido por la gingivitis.

Periodontal diseases are considered among the most common among oral pathologies. Its frequency is increasingly higher in the population and there are several systemic pathologies and habits that worsen its clinical condition. The objective of this work was to determine the frequency and clinical characteristics of patients with periodontal diseases who attend the periodontics department at the Autonomous University of Asunción in the period from 2011 to 2019. Observational, descriptive, retrospective study, 477 clinical records were processed. of patients from the Department of Periodontics at the Autonomous University of Asunción from 2011 to 2019. The type of sampling used was non-probabilistic for convenience. Of the 477 records, only 317 patients who met the inclusion criteria were analyzed.

The most frequent clinical diagnosis of the studied population was chronic periodontitis, followed by gingivitis.

RESUMO

ABSTRACT Objective In psychiatry, History Taking(HT) and Mental Status Examination are the only information source for diagnosis, resulting in reliability and validity issues. Standard Diagnostic Interviews(SDI) were prescribed as a solution for diagnostic unreliability but not used in clinical practice. Our objective is to describe and consolidate the "must be collected data" in psychiatric HT, and reasons why some information must be collected for an adequate diagnostic hypothesis generation. Methods Researchers and lecturers from different countries were consulted about Textbooks of Clinical Psychiatry, as a privileged source of consolidated HT information in psychiatric training, using a snowball methodology, complemented by references review and most sold textbooks. Data were systematically extracted by two authors, and then comprehensively synthesized. Results Twenty-five textbooks, from sixteen different countries, were accessed. We did not find a standard model, nor clear reasons for why HT components were chosen, but the manual's information grossly overlaps, suggesting a "validated by tradition" model in psychiatry. Conclusion The "must be collected data" are both risk factors and prototype building blocks for mental disorders, with different anti-bias strategies. HT content suggested by textbooks is different from what is addressed by SDI, and a consensual "minimum information" for diagnostic reasoning was described.

RESUMO Objetivo Em psiquiatria, a anamnese e o Exame Psíquico são as únicas fontes de informação para o diagnóstico, resultando em problemas de confiabilidade e validade. As entrevistas diagnósticas padronizadas (SDI) foram prescritas como uma solução para a falta de confiabilidade diagnóstica, mas não são utilizadas na clínica. Nosso objetivo é descrever e consolidar os "dados mínimos que devem ser coletados" na anamnese psiquiátrica, e as razões pelas quais estes dados devem ser coletados para a geração de hipóteses diagnósticas. Métodos Pesquisadores e professores de psiquiatria de diferentes países foram consultados sobre os livros didáticos de Psiquiatria Clínica usados em seus países. Usando uma metodologia de bola de neve, complementada por revisões de referências e os livros didáticos mais vendidos, selecionamos os livros texto como fontes de informação consolidada para o treinamento de anamnese em psiquiatria. Os dados foram sistematicamente extraídos por dois autores, e depois sistematizados e comentados. Resultados Vinte e cinco livros didáticos, de dezesseis países diferentes, foram acessados. Não encontramos um modelo padrão, nem razões claras para a escolha dos componentes da anamnese, mas as informações clínicas dos livros se sobrepõem consistentemente, sugerindo um modelo "validado pela tradição" em psiquiatria. Conclusões Os "dados mínimos que devem ser coletados" são tanto fatores de risco como blocos de construção de protótipos para distúrbios mentais, com diferentes estratégias anti-viés. O conteúdo da anamnese sugerido pelos manuais é diferente do abordado pelas SDIs, e a "informação mínima" para o raciocínio diagnóstico foi descrita.

ABSTRACT Purpose To validate the content of the Speech-Language Pathology Concordance Test called FonoTCS. Methods This is a content validation study of the instrument. Five speech-language pathologists, all with doctoral degrees and teaching experience, averaging 24.8 years of professional practice, participated in the development of FonoTCS and reached a consensus during the process. Thirty questions and 120 items were created, covering seven areas of speech-language pathology expertise across three domains. For content validation, FonoTCS was electronically sent to 15 evaluators to respond to a questionnaire with five questions, rated on a five-point scale, regarding the criteria of clarity, ethics, and relevance of the questions. The Corrected Content Validity Coefficient was calculated for all statements to analyze the responses. Questions with agreement percentages equal to or less than 80% were revised. Results Thirteen evaluators, all female, with an average age of 39.07 years, including eight with master's degrees and five with doctoral degrees, and an average clinical practice experience of 15.38 years, participated in the analysis. The average Corrected Content Validity Coefficient values for the clarity criterion were 0.93 and 0.95, for the relevance criterion 0.98 and 0.92, and for the ethics criterion 0.99. Two questions received scores of 0.78 and 0.80, both related to the audiology area in the assessment/diagnosis domain, specifically question 2 regarding the relevance criterion. These questions were reviewed and restructured by the judges. Conclusion FonoTCS is a valid instrument from a content perspective.

RESUMO

Introducción: El cáncer vesical es una enfermedad que afecta, generalmente, a pacientes masculinos de la tercera edad. Este tumor tiene dos formas principales de manifestarse: como tumor superficial y de bajo grado, o como neoplasia invasora de alto grado. La mayoría de los pacientes afectados con esta enfermedad presentan como factor de riesgo, el consumo de tabaco. Objetivo: Contribuir al conocimiento de la comunidad científica en lo relativo a los factores de riesgo y al síntoma principal asociados al cáncer vesical en pacientes adultos de la tercera edad. Métodos: Se realizó una revisión sistemática sobre el tema en las bases de datos: SciELO, EBSCO, Scopus, PubMed, y en revistas de Urología. Los artículos fueron publicados en idioma español o inglés. Se realizó un análisis del contenido para lograr la actualización teórica del tema. Conclusiones: El cáncer vesical es una enfermedad multifocal que provoca la aparición de varias neoformaciones dentro del epitelio transicional, en toda su extensión. La presencia de hematuria asintomática en los pacientes adultos fue la causa más común de consulta con el urólogo. Dentro de los factores de riesgo, el principal fue el consumo de tabaco.

RESUMO

Abstract: Tinnitus detection and characterization requires a carefully elaborated diagnosis mainly owing to its heterogeneity nature. The present investigation aims to find features in Electroencephalographic (EEG) signals from time and frequency domain analysis that could distinguish between healthy and tinnitus sufferers with different levels of hearing loss. For this purpose, 24 volunteers were recruited and equally divided into four groups: 1) controls, 2) slow tinnitus, 3) middle tinnitus and 4) high tinnitus. EEG signals were registered in two states, with eyes closed and opened for 60 seconds. EEG analysis was focused on two bandwidths: delta and alpha band. For time domain, the EEG features estimated were mean, standard deviation, kurtosis, maximum peak, skewness and shape. For frequency domain, the EEG features obtained were mean, skewness, power spectral density. Normality of EEG data was evaluated by the Lilliefors test, and as a result, the nonparametric technique Kruskal-Wallis H statistic to test significance was applied. Results show that EEG features are more differentiable between tinnitus sufferers and controls in frequency domain than in time domain. EEG features from tinnitus patients with high HL are significantly different from the rest of the groups in alpha frequency band activity when shape and skewness are computed.

Resumen: La detección y caracterización del acúfeno requiere un diagnóstico cuidadosamente elaborado debido principalmente a su naturaleza heterogénea. La presente investigación tiene como objetivo encontrar características en las señales electroencefalográficas (EEG) a partir del análisis del dominio del tiempo y frecuencia que podrían distinguir entre pacientes sanos y con acúfeno con diferentes niveles de pérdida auditiva. Para ello, se reclutaron 24 voluntarios y se dividieron por igual en cuatro grupos: 1) controles, 2) acúfeno bajo, 3) acúfeno medio y 4) acufeno alto. La actividad EEG se registró en reposo en dos condiciones: ojos cerrados y abiertos durante un minuto. El análisis de EEG se centró en anchos de banda delta y alfa. Para el dominio del tiempo, las características del EEG estimadas fueron la media, la desviación estándar, la curtosis, el pico máximo, la asimetría y la forma. Para el dominio de la frecuencia, las características de EEG obtenidas fueron media, asimetría, densidad espectral de potencia. La normalidad de los datos del EEG se evaluó mediante la prueba de Lilliefors y, como resultado, se aplicó la técnica no paramétrica del estadístico H de Kruskal-Wallis para probar la significación. Los resultados muestran que las características del EEG son más diferenciables entre los pacientes con acúfeno y los controles en el dominio de la frecuencia que en el dominio del tiempo. Las características del EEG de los pacientes con acúfeno con alta pérdida de audición son significativamente diferentes del resto de los grupos en la actividad de la banda de alfa cuando se calculan la forma y la asimetría.

RESUMO

Introducción. La prueba de provocación oral (PPO) para el diagnóstico de alergia a las proteínas de la leche de la vaca (APLV) presenta riesgos y requiere de recursos. Nuestro objetivo fue evaluar condiciones y pruebas complementarias para identificar una alta probabilidad de APLV. Población y métodos. Análisis secundario sobre estudio de pacientes atendidos en una unidad de alergia entre 2015 y 2018. Se determinaron las probabilidades prepruebas asociadas a los síntomas y sus combinaciones, y las probabilidades pospruebas luego de realizadas pruebas cutáneas y determinación de inmunoglobulina E (IgE) sérica. Resultados. Se evaluó la información de 239 pacientes. Se observaron probabilidades mayores al 95 % en pacientes con angioedema y combinación de urticaria y vómitos. Usando puntos de corte propuestos por Calvani et al., la combinación de vómitos con rinitis, sin angioedema, también superó el 95 %. Conclusión. Se ofrece una metodología para identificar pacientes en los que puede diagnosticarse APLV sin realización de PPO.

Introduction. The oral food challenge (OFC) for the diagnosis of cow's milk protein allergy (CMPA) poses risks and requires resources. Our objective was to assess conditions and complementary tests used to identify a high probability of CMPA. Population and methods. Secondary analysis of a study of patients seen at a unit of allergy between 2015 and 2018. Pre-testing probabilities associated with symptoms and their combinations and post-testing probabilities after skin prick testing and serum immunoglobulin E (IgE) levels were determined. Results. The data from 239 patients were assessed. A probability greater than 95% was observed for angioedema and a combination of urticaria and vomiting. Based on the cut-off points proposed by Calvani et al., the combination of vomiting with rhinitis, without angioedema, also exceeded 95%. Conclusion. A methodology is provided to identify patients in whom CMPA may be diagnosed without an OFC.

RESUMO

Introducción: En el proceso de capacitación continua de los estudiantes de Medicina resulta necesario incorporar temas de actualidad; asimismo, es importante conocer los problemas para buscar soluciones con el apoyo de la ciencia. Objetivo: Diagnosticar el proceso formativo del estudiante de Medicina en cuanto a la detección de secuelas discapacitantes pos-COVID-19. Métodos: Se realizó un estudio observacional, descriptivo y transversal, con enfoque cualitativo, de 20 estudiantes del quinto año de la carrera de Medicina, pertenecientes a la Universidad de Ciencias Médicas de Camagüey, durante su estancia por la asignatura Salud Pública, desde julio hasta diciembre del 2022. Para tal propósito se diseñó y aplicó un instrumento evaluativo con dimensiones e indicadores. Resultados: Se halló que 50,0 % de dichos estudiantes se ubicó en el rango de edad de 21-26 años, mientras que 65,0 % correspondió al sexo femenino. La dimensión cognitiva fue evaluada de mal, pues 3 indicadores, de los 4 que la integraban, recibieron esa calificación; del mismo modo sucedió con la dimensión instrumental. En cambio, la dimensión actitudinal y sus 2 indicadores fueron calificados de bien. Conclusiones: Existieron insuficiencias en el proceso formativo del estudiante de Medicina, lo que obstaculiza su desempeño profesional. Sobre la base del diagnóstico realizado, se confirma como fortaleza el interés por la búsqueda de información relacionada con la detección de secuelas discapacitantes pos-COVID-19.

Introduction: In the continuous training process of medical students, it is necessary to incorporate current issues; likewise, it is important to know the problems to seek solutions with the science support. Objective: To diagnose the training process of medical students as for the detection of incapacitating sequelae post-COVID-19. Methods: An observational, descriptive and cross-sectional study, with qualitative approach, of 20 students from 5th year of Medicine career, belonging to the University of Medical Sciences in Camagüey was carried out during their stay for the Public Health subject, from July to December, 2022. For such a purpose it was designed and applied an evaluative instrument with dimensions and indicators. Results: It was found that 50.0% of these students were in the age range of 21-26 years, while 65.0% were female. The cognitive dimension was evaluated as bad because 3 indicators, of the 4 that made it up, received that qualification; the same happened with the instrumental dimension. On the other hand, the attitudinal dimension and its 2 indicators were qualified as good. Conclusions: Inadequacies existed in the training process of medical students, which block their professional performance. On the base of the diagnosis, the interest in searching for information related to the detection of post-COVID-19 incapacitating sequelae is confirmed as strength.
