Dental Status of Firefighters of Rio de Janeiro State and Comparison with Brazilian Oral Health Surveys

ABSTRACT Objective: This cross-sectional study aimed to assess clinical dental status in military firefighters of Rio de Janeiro State and compare data with Brazilian National and Regional oral health surveys. Material and Methods: A sample of 926 military firefighters was examined using the visible biofilm index, the DMFT index and the Community Periodontal Index (CPI). Clinical exams were performed by 15 trained dentists. The Kruskal-Wallis test and Mann-Whitney test with Bonferroni correction were used. Results: Higher biofilm accumulation was associated with increased age. The mean DMFT index for the whole sample of this study was 12.74 (±7.03), and the 'filled' component was the most prevalent (69.9%), whereas the 'decayed' and 'missing' components were, respectively, 8.4% and 21.7%. There was a higher prevalence of periodontal diseases with increasing age, ranging from 57.1% in firefighters of 34 years or less to 70.5% in the ones between 35 and 44 years old and 75.4% in participants at age 45 years or older. Clinical dental status of the military firefighters who belonged to the age group 35-44 was better than the one observed for the Brazilian population at the same age range. However, pathological conditions that can be solved with health promotion strategies associated with dental procedures of low complexity still persist. Conclusion: These results suggest that the availability of dental health care services itself does not represent the most effective approach to the oral health problems found in the studied population.

Correlation Between Clinical and Histopathologic Diagnosis of Oral Potentially Malignant Disorder and Oral Squamous Cell Carcinoma

ABSTRACT Objective: To determine the frequency of oral potentially malignant disorders and Oral Squamous Cell Carcinoma (OSCC) and evaluate the consistency between their clinical and pathological features. Material and Methods: This retrospective study was conducted on records with a diagnosis of oral leukoplakia, oral erythroplakia, erythroleukoplakia, actinic cheilitis, lichen planus, and OSCC in the Pathology Department of Kerman dental school from September 1997 to September 2017. Data were analyzed in SPSS 21 at the significance level of ≤5%. Results: There were 378 cases of oral potentially malignant disorders and 70 cases of OSCC with a mean age of 46.82 ± 15.24 years. Buccal mucosa was the most frequent site, and lichen planus the most common lesion. Females were significantly older than males in leukoplakia and carcinoma in situ lesions. Clinical diagnosis and histopathology were consistent in 69.03% of cases. Conclusion: Clinical and histopathological diagnoses were consistent in 69.03% of records. The highest degree of clinical compliance with histopathology was observed in OSCC. Dentists should pay attention to oral potentially malignant disorders for early diagnosis to prevent their transformation to malignancy.

Cultivo mediante hisopado superficial versus cultivo de la biopsia de tejidos profundos en la infección del pie diabético / Culture through superficial swab versus deep tissue biopsy in the diabetic foot infection

RESUMEN Introducción: para lograr el adecuado y precoz diagnóstico de la infección en pie diabético, es necesario la obtención de una muestra bacteriológica de calidad para la identificación del germen causal. Objetivo: identificar posibles relaciones entre los resultados obtenidos, en el cultivo realizado mediante hisopado superficial versus el obtenido mediante biopsia de los tejidos profundos en la infección del pie diabético. Materiales y métodos: se realizó un estudio explicativo observacional, longitudinal, prospectivo en el Servicio Provincial de Angiología y Cirugía Vascular del Hospital Provincial Clínico Quirúrgico Universitario "Comandante Faustino Pérez", durante un periodo de 3 años desde enero del 2016 hasta diciembre del 2018. Una selección muestral no probabilística determinó una muestra constituida por 138 extremidades en 132 pacientes con diagnóstico clínico de pie diabético infectado, que requirieron cirugía para desbridamiento de la lesión. Aceptaron ser incluidos en la investigación y para el aislamiento del germen causal fueron empleados ambos métodos de cultivo: hisopado superficial y biopsia de los tejidos profundos. Resultados: el promedio de microorganismos aislados se incrementó en relación con la severidad de la infección del pie diabético, con mayor incremento en el aislamiento hecho por el hisopado superficial. El hisopado superficial posee pobre correlación con los gérmenes aislados mediante el cultivo de la biopsia de los tejidos profundos. Conclusiones: las muestras deben ser obtenidas preferentemente por curetaje. En el diagnóstico de la infección del pie diabético es de gran utilidad, por su rapidez y concordancia con los resultados del cultivo, efectuar siempre una tinción de Gram a partir del mismo sitio (AU).

ABSTRACT Introduction: to arrive to an adequate and precocious diagnosis of the diabetic foot infection, it is necessary to obtain a qualitative bacteriological sample to identify the causing germ. Objective: to identify possible relationships between the results obtained both, in the culture made through superficial swab and the culture obtained from deep tissues biopsy in the diabetic foot infection. Materials and methods: a prospective, longitudinal, observational, explicative study was carried out in the Provincial Service of Angiology and Vascular Surgery of Provincial University Clinical Surgical Hospital "Comandante Faustino Pérez", in a period of three years, from January 2016 to December 2018. A non-probabilistic sampling choose a sample of 138 lower limbs in 132 patients with clinical diagnosis of infected diabetic foot, who required surgery for lesion debridement. They gave their consent to be included in the research; for the isolation of the casual germ were used both culture methods, superficial swab and deep tissues biopsy. Results: the average of isolated microorganism increased in relation to the severity of the diabetic food infection, with higher increase in the isolation obtained by superficial swab. The superficial swab shows poor correlation with the germ isolates by the culture the deep tissue biopsy. Conclusions: the samples should be gathered preferably by curettage. In the diagnosis of the diabetic foot infection, it is very useful, due to its speed and concordance with the culture results, to make always a Gram staining beginning from the same place (AU).

Hepatoesplenomegalia relacionada a linfoma de Burkitt en paciente pediátrico / Hepatoesplenomegalia related to Burkitt´s lymphoma in a pediatric patient

RESUMEN El linfoma de Burkitt, se trata de un subtipo poco frecuente del linfoma no Hodgkin, con elevada frecuencia en aquellos pacientes con sida. La hepatoesplenomegalia es un signo clínico de gran importancia para el diagnóstico oportuno de algunas patologías; entre los mecanismos de formación de la hepatoesplenomegalia se encuentra la infiltración celular, ocasionada por la migración de células tumorales. Se presenta por inflamaciones debido a la presencia de infecciones por virus o bacterias las cuales son muy comunes en pacientes con sida. Se presentó un caso de un paciente masculino de 4 años, diagnosticado con VIH positivo, con la configuración correspondiente de criterios clínicos en clasificación C para sida. El cual desarrolló a nivel de cavidad oral un Burkitt primario, que se acompañó de hepatoesplenomegalia. Se pretendió describir la relación y el comportamiento de este tipo de linfoma con la hepatoesplenomegalia, así como la repercusión a nivel del sistema estomatognático, a nivel sistémico y el plan de tratamiento. Por el cuadro clínico e inmunológico del paciente estudiado, se planteó un pronóstico reservado por presentar un cuadro clínico infrecuente, en el que se observó Burkitt; tanto a nivel del sistema estomatognático como a nivel abdominal. Se hizo necesario realizar un diagnóstico oportuno y certero para iniciar el tratamiento a tiempo, se comenzó inmediatamente con tratamiento (AU).

ABSTRACT Burkitt lymphoma (BL) is a rare subtype of non-Hodgkin lymphoma, with high frequency in those patients with AIDS. Hepatosplenomegaly is a clinical sign of great importance for the timely diagnosis of some pathologies; cellular infiltration is found among the mechanisms of hepatosplenomegaly formation; it is caused by the migration of tumor cells. It emerges by inflammations due to the presence of infections by virus or bacteria which are very common in patients with AIDS. The authors present the case of a male patient, aged 4 years, with a positive HIV diagnosis, and the correspondent configuration of clinical criteria in C classification for AIDS, who developed a primary Burkitt lymphoma at the level of oral cavity We present the case of a 4-year-old male patient diagnosed with HIV positive, with the corresponding configuration of clinical criteria in classification C for AIDS; who developed a primary LB at the oral cavity level that was accompanied by hepatosplenomegaly. The authors pretended to describe the relation and behavior of this kind of lymphoma with hepatosplenomegaly, and also the repercussion at the stomatognathic level, at the systemic level and the treatment plan. Due to the clinical and immunological characteristics of the studied patient a reserved prognosis was given because of presenting infrequent clinical characteristics in which a Burkitt was observed both, at the stomatognathic and at the abdominal level. It was necessary to make an opportune and accurate diagnosis to begin the treatment on time (AU).

Antecedentes: La apendicitis aguda (AA) es la urgencia quirúrgica más frecuente alrededor del mundo. Su diagnóstico precoz y certero es fundamental para evitar cirugías innecesarias y complicaciones asociadas a su evolución natural. Objetivo: Determinar la sensibilidad y especificidad diagnóstica de la escala RIPASA en pacientes con sospecha clínica de apendicitis aguda. Material y métodos: Estudio analítico, transversal, observacional y retrospectivo; se incluyeron todas las piezas de apendicectomías de pacientes de ambos sexos mayores de 18 años operados con diagnóstico clínico de apendicitis aguda que consultaron entre el 1º de enero y el 31 de diciembre de 2017. Como procedimiento de referencia (gold standard) diagnóstico se analizaron los hallazgos histopatológicos del apéndice extirpado. Se aplicó la escala RIPASA a cada uno de los pacientes (punto de corte de 7,5). Se realizó estadística descriptiva y pruebas diagnósticas (sensibilidad, especificidad, valor predictivo positivo [VPP], valor predictivo negativo [VPN]). Resultados: Se incluyeron 68 apendicectomías. Cincuenta y siete muestras (83,82%) fueron positivas para apendicitis aguda. El promedio de edad fue 43,32 años. De los 38 hombres, 32 (84,21%) tuvieron diagnóstico histopatológico de AA. De las 30 mujeres, 25 (83,33%) tuvieron AA. Para la escala RIPASA, 54 pacientes tuvieron un resultado verdadero positivo (punto de corte ≥7,5 e histología positiva para AA) resultando con una sensibilidad del 93%, especificidad del 40%, VPP del 90%, VPN del 50%, razón de verosimilitud positiva de 1,55 y razón de verosimilitud negativa de 0,175. Conclusión: El puntaje (score) RIPASA ha demostrado una excelente sensibilidad y especificidad para el diagnóstico clínico de AA de manera rápida, simple y no invasiva.

Background: Acute appendicitis (AA) is the most common surgical emergency worldwide. Its correct and early diagnosis is essential to avoid unnecessary surgeries and complications associated with its natural history. Objective: The aim of this study was to determine the diagnostic sensitivity and specificity of the RIPASA score in patients with suspected AA. Material and methods: This analytical, cross-sectional, observational and retrospective study included appendectomy specimens of patients of both sexes > 18 years operated on with clinical diagnosis of AA between January 1 and December 31, 2017. The histopathological examination of the appendectomy specimens was considered the gold standard diagnostic test. A score of 7.5 for the RIPASA score was chosen as cut-off value. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: A total of 68 appendectomies were included; 57 (83.82%) specimens were positive for acute appendicitis. Mean age was 43.32 years. The histological diagnosis of AA was present in 32 (84.21%) men and in 25 (83.33%) women. For the RIPASA score, 54 patients had a true positive result (cut-off point ≥ 7.5 and positive histology for AA) with a sensitivity of 93%, specificity of 40%, PPV of 90%, NPV of 50%, positive likelihood ratio of 1.55 and negative likelihood ratio of 0.175. Conclusion: The RIPASA score has demonstrated excellent sensitivity and specificity for the clinical diagnosis of AA in a fast, simple and non-invasive fashion.

Biomarcadores en las neoplasias mieloproliferativas clásicas BCR-ABL1 negativas / Biomarkers in Classical Myeloproliferative Neoplasms BCR-ABL1 negative

Introducción: Los biomarcadores son útiles en la definición del diagnóstico, pronóstico y seguimiento de múltiples enfermedades. La detección o medición de uno o más biomarcadores específicos representan alteraciones en vías genéticas o epigenéticas que controlan la proliferación, diferenciación o muerte celular. Las neoplasias mieloproliferativas constituyen un grupo fenotípicamente diverso de hemopatías malignas de origen clonal, caracterizadas por una sobreproducción simple o multilineal de los elementos eritroides, mieloides y megacariocíticos; así como de una marcada predisposición a la trombosis, sangramiento y transformación leucémica. Dentro de ellas se incluyen: la policitemia vera, la trombocitemia esencial y la mielofibrosis primaria, conocidas como neoplasias mieloproliferativas clásicas BCR-ABL1 (o cromosoma Philadelfia) negativas. Las mutaciones somáticas en genes como JAK2, MPL y CARL se comportan como mutaciones drivers iniciadoras, responsables del fenotipo mieloproliferativo. Métodos: Se revisaron artículos relacionados publicados en los últimos años, en algunas bases de datos de la Biblioteca Virtual de Salud. En esta revisión se exponen los mecanismos moleculares generales de esas mutaciones y su expresión clínica; se hace referencia a las neoplasias mieloproliferativas triple negativas y sus implicaciones clínicas y se indica el algoritmo diagnóstico propuesto por la Organización Mundial de la Salud que incluye los nuevos biomarcadores. Conclusiones: El estudio molecular proporciona información valiosa para el diagnóstico y seguimiento de las neoplasias mieloprolifrativas, pero no logra diferenciar entre cada una de ellas. Por esto, se requiere de la adecuada aplicación del método clínico para llegar a un diagnóstico certero con ayuda de otros exámenes complementarios(AU)

Introduction: Biomarkers are useful in the definition of diagnosis, prognosis and monitoring of multiple diseases. The detection or measurement of one or more specific biomarkers represents alterations in genetic or epigenetic pathways that control proliferation, differentiation or cell death. The myeloproliferative neoplasms constitute a phenotypically diverse group of malignant hemopathies of clonal origin, characterized by a simple or multilinear overproduction of the erythroid, myeloid and megakaryocytic elements; as well as a marked predisposition to thrombosis, bleeding and leukemic transformation. These include: polycythemia vera, essential thrombocythemia, and primary myelofibrosis, known as classical negative myeloproliferative neoplasms BCR-ABL1 (or Philadelphia chromosome). Somatic mutations in genes such as JAK2, MPL and CARL behave as initiating driver mutations responsible for the myeloproliferative phenotype. Methods: Articles published in the last years were reviewed in some databases of the Virtual Health Library (VHL). In this review we expose the general molecular mechanisms of these mutations and their clinical expression; reference is made to the triple negative myeloproliferative neoplasms and their clinical implications and the diagnostic algorithm proposed by the World Health Organization that includes the new biomarkers is indicated. Conclusions: The molecular study provides valuable information for the diagnosis and monitoring of myeloproliferative neoplasms, but fails to differentiate between each of them. Therefore, the appropriate application of the clinical method is required to arrive at an accurate diagnosis with the help of other complementary tests(AU)

El padecer como diagnóstico de la enfermedad / Suffering as a diagnosis of the disease

Introducción: La vivencias emocionales de las enfermedades y su cuidado reciben atención insuficiente en las condiciones actuales de una medicina altamente biologicista. Objetivo: Profundizar en el concepto del padecer como componente del diagnóstico con enfoque psicosocial en clínica. Métodos: Se realizó una búsqueda en las bases de datos PubMed, SciELO y Lilacs utilizando las palabras claves: padecer; afectación; enfermedad, illness, sickness, disease. Desarrollo: El diagnóstico médico se centra en la entidad nosológica que representa alteraciones estructurales y funcionales. La afectación se vincula a la vida de relaciones sociales del enfermo en la que supone determinado grado de invalidez y en el padecer, el cual es una expresión de la dimensión psicológica cuya complejidad se centra en la respuesta afectiva identificable por las emociones y sentimientos. El padecer tiene un carácter individual según los rasgos de personalidad, la biografía del paciente, las características de su enfermedad (aguda o crónica), el contexto en el que surge y se desarrolla el problema de salud y las cualidades del proceso de atención. El afrontamiento del padecer del paciente puede verse mejor desde una visión alostática. Conclusiones: El padecer de las enfermedades, también conocido como cuadro interno de la enfermedad, tiene como centro la respuesta emocional pero no se limita a ella. Exige conocer al enfermo como persona y su red de apoyo con vistas a facilitarle una respuesta adaptativa beneficiosa a su nueva condición(AU)

Introduction: The emotional experiences of diseases and their care receive insufficient attention in the current conditions of highly biologic oriented medicine. Objective: To deepen the concept of suffering as a component of diagnosis with a psychosocial approach in the clinic. Methods: A search in PubMed, SciELO and Lilacs databases was performed using suffering; affectation; disease, illness, sickness, disease as keywords. Discussion: The medical diagnosis focuses on the nosological entity that represents structural and functional alterations. Suffering is linked to the social relations of the patient in which certain degree of disability and suffering are supposed, which is an expression of the psychological dimension whose complexity focuses on the emotional response identifiable by emotions and feelings. Suffering has an individual character according to the personality traits, the patient´s history, the characteristics of the illness (acute or chronic), the context in which the health problem arises and advances and the qualities of the care process. Coping with the patient's suffering can be better understood from an allostatic view. Conclusions: Suffering from diseases, also known as internal symptoms of the disease, is centered on the emotional response but it is not just limited to it. Knowing the patient as a whole person and their support network is required to facilitating beneficial adaptive response to the new condition(AU)

La actualización del método clínico / Updating on the clinical method

En la actualidad existe desarrollo de la tecnociencia aplicada a la medicina con tendencia a relegar a un segundo plano el método clínico. Las diferentes escuelas de medicina del mundo, incluyendo la cubana, han comenzado una modernización del método clínico, el cual está basado en un método científico, por lo que es importante centrar su enseñanza en aspectos eminentemente prácticos, además de usar adecuadamente los exámenes complementarios para ratificar el diagnóstico, pronóstico y tratamiento del enfermo. El objetivo de esta investigación es aunar criterios sobre la enseñanza y aplicación del método clínico, para ello se hacen algunas reflexiones sobre su utilidad práctica, los programas actuales de su enseñanza y los textos en los que se basa. La conceptualización del método clínico es fruto de la Escuela Cubana de Clínica, donde los internistas han tenido una función importante en los últimos 50 años. Los especialistas de esta área del conocimiento, junto a todos los médicos asistenciales que están en la necesidad de utilizar este método para el manejo de sus enfermos, están llamados a continuar con la tarea de mantener y transmitir la esencia misma de la clínica, en medio de un ambiente inestable y cambiante(AU)

At present, due to the development of techno science applied to medicine, there is a tendency to overshadow the clinical method. Different medical schools in the world, including the Cuban school, have begun the modernization of the clinical method, which is based on the scientific method. Therefore, it is important to focus teaching on the eminently practical aspects, in addition to properly using complementary tests to confirm the patient´s diagnosis, prognosis and treatment. The objective of this research is to combine criteria on the teaching and use of the clinical method. Some reflections arise from its practical convenience, current syllabus and the texts on which it is based. The conceptualization of the clinical method is the result of the Cuban School of Clinic, where internists have played important role in the last 50 years. The specialists of this area of knowledge, together with all the medical assistants who need to use this method for treating their patients, are called to continue with the task of maintaining and transmitting the very essence of the clinic, in the midst of unstable and changing circumstances(AU)

Caracterización de las enfermedades valvulares congénitas en la edad pediátrica / Characterization the pediatric patients with diagnostic of illnesses congenital valvulares

Introducción: Las valvulopatías congénitas son un grupo de entidades en las cuales la principal alteración anatomofuncional está en las válvulas cardiacas. Objetivo: Caracterizar los pacientes pediátricos nacidos vivos con diagnósticos de valvulopatías congénitas. Métodos: Se realizó una investigación descriptiva retrospectiva a partir de los registros de valvulopatías congénitas del Servicio de Cardiología del Hospital Pediátrico Universitario José Luis Miranda en Santa Clara, Cuba, en el periodo de 2005 a 2016. La población estuvo conformada por los 147 niños nacidos vivos con diagnóstico de valvulopatías congénitas. Se empleó un muestreo no probabilístico intencional por criterios y la muestra quedó conformada por 143. La recogida de la información se realizó a través de la revisión documental de las historias clínicas. Resultados: La tasa de incidencia de la valvulopatías congénitas fue de 1,5 x 1 000 nacidos vivos, predominó la estenosis pulmonar que agrupó el 70,6 por ciento de los diagnosticados. Se encontró predominio del sexo masculino con 50,3 por ciento, se determinó que 45,5 por ciento de los casos se diagnosticaron antes de los 29 días de nacido, período que incluye un diagnóstico prenatal. Conclusiones: El desarrollo del diagnóstico prenatal de las cardiopatías congénitas ha posibilitado la disminución de la incidencia de las malformaciones más complejas. El conocimiento de las enfermedades congénitas del corazón contribuye a operar de forma segura y con resolución anatómica completa a muchos de estos niños en el período prenatal o cuando son lactantes pequeños, para evitar el deterioro global de estos cuando la cardiopatía no está resuelta(AU)

Introduction: The congenital valvulopatías is a group of entities in which the main alteration anatomofuncional is in the heart valves. Objective: To characterize the pediatric patients with diagnostic of born congenital valvulopatías. Methods: He/she was carried out a retrospective descriptive investigation starting from the registrations of congenital valvulopatías of the service of Cardiology of the Hospital Pediatric University student José Luis Miranda in the period of 2005 at the 2016. The population was conformed by the 147 alive born children with diagnostic of congenital valvulopatías, a sampling was not used intentional probabilístico by approaches, being conformed the sample by 143. The collection of the information was carried out through the documental revision of the clinical histories. Results: The rate of incidence of the congenital valvulopatías was of 1,5 x 1000 born alive, the lung estenosis prevailed containing to 70,6 percent of those diagnosed he/she was prevalence of the masculine sex in 50,3 percent, it was determined that 45,5 percent of the cases was diagnosed before the 29 days where a prenatal diagnosis is included. Conclusions: The development of the prenatal diagnosis of the congenital cardiopatías has facilitated the decrease of the incidence of the most complex malformations. The knowledge of the congenital illnesses of the heart contributes to operate in a sure way and with complete anatomical resolution to many of these children in the prenatal period or when they are small nurslings, to avoid the global deterioration of these when the cardiopatía is not resolved(AU)

Compatibility of Clinical and Histopathological Diagnosis of Oral Lesions in Iranian Patients

Objective: To determine compatibility between clinical diagnosis and the pathological reports of biopsies from oral lesions. Material and Methods: In this descriptive study, 1146 clinical files of patients referring to Tabriz Faculty of Dentistry from 2004 to 2016 were retrieved and evaluated. The kappa coefficient was calculated for each file for compatibility of clinical and pathological diagnosis. Results: In relation to clinical (40.2%) and pathological (39.2%) diagnosis, irritational lesions of soft tissues exhibited the highest frequency. In 72.3% of cases, the clinical and pathological diagnosis were compatible and in 27.7% of cases these diagnosis were not compatible. The highest compatibility rates were detected for irritational lesions of soft tissues (81.5%) and mucocutaneous lesions (76.9%). There was no compatibility for osseous malignant tumors, inflammatory tissues, granulation tissues, metastatic lesions and hematologic disorders. Conclusion: Approximately one-third of clinical and histopathological diagnosis were not compatible. Therefore, to reach a correct diagnosis, the clinical, radiographic and histopathological views should be evaluated simultaneously.

Diagnostic Validity of Self-Perceived Dental Caries in Indonesian Young Adolescents Aged 12-15 Years

Objective: To compare self-perceived information and clinically diagnosed dental caries status among Indonesian children aged 12­15 years. Material and Methods: In this cross-sectional study, a questionnaire was used to obtain self-perceived information. Clinical examinations were conducted to determine the mean number of decayed, missing or filled teeth (DMFT) and the presence of severely decayed teeth with visible pulpal involvement, ulceration caused by dislocated tooth fragments, fistula, and abscess (PUFA). The study included 494 children aged 12­15 years recruited from six junior high schools in Jakarta, Indonesia. The clinical examination results and responses to the self-perceived assessment questionnaire were compared to determine the sensitivity and specificity. Results: The proportions of children with dental caries and clinical consequences of untreated dental caries in this study were 69.4% and 17.6%, respectively, with mean DMFT and PUFA index scores of 2.4 and 0.2, respectively. For the DMFT index, the self-perceived need for oral treatment had the highest sensitivity (86%), while the dental pain had the highest specificity (89%). For the PUFA index, the self perceived oral health condition had the highest sensitivity (92%), while the self-perceived dental pain had the highest specificity (82%). However, none of the self-perceived variables had both high sensitivity and specificity. Conclusion: Self-perceived information obtained from the questionnaire can not properly evaluate the clinical status of dental caries.

Conclusões: A prevalência de disfunção erétil foi elevada. A DE esteve associada a piora da QV em pacientes com DAC

Background: Erectile dysfunction (ED) and coronary artery disease (CAD) share the same risk factors and the associations between ED, quality of life (QoL) and CAD have been the subject of recent studies. Objective: To evaluate whether ED is associated with worsening QoL in patients with CAD. Methods:A cross-sectional, multicenter, prospective and analytic study was carried out from EDcember 2014 to April 2016, which recruited 304 men (mean age: 57 ± 9.9 years) with clinical diagnosis of CAD. QoL was assessed using Short Form-36 and ED by the International Erectile Function InEDx. EDscriptive and analytical statistical analyzes were performed, and the Kruskal-Wallis non-parametric test was used to test whether there are significant differences in each quality of life domain when comparing different types of ED. For all tests, p ≤ 0.05 was consiEDred significant. Results: The prevalence of ED was 76.3%. The median and percentiles 25 and 75 of each life quality domain according to the absence of ED; mild ED, mild to moderate, moderate and severe ED and severe ED, respectively, were: Functional capacity: 85 (63-100), 75 (50 -95), 60 (32-85), 55 (35-75), 50 (30-70), p < 0.001; Physical aspects: 87 (0-100), 40 (0-100), 0 (0-100), 0 (0-31), 0 (0-12), p < 0.001; Pain: 72 (51-100), 66 (51-100), 74 (51-100), 62 (51-100), 51 (31-62), p = 0.001; General state of health: 77 (62-87), 72 (57-77), 67 (55-82), 67(59-75), 52 (37-68), p < 0.001; Vitality: 75 (60-85), 65 (50-75), 65 (55-75), 60 (43-75), 50 (32-65), p < 0.001; Social Aspects: 87 (62-100), 87 (62-100), 87 (68-100), 75 (62-100), 75 (50-93), p = 0.139; Emotional Aspects: 100 (58-100), 100 (33-100), 100 (33-100), 100 (0-100), 0 (0-100), p = 0.001; Mental health: 80 (67-89), 72 (60-84), 72 (66-80), 68 (58-80), 56 (50-74), p < 0.001. Conclusions: The prevalence of erectile dysfunction was high. ED was associated with worsening of QoL in patients with CAD

Changes in the Immuno-Expression of Galectins -1, -3 and -7 in Relation to the Biological Behavior of Lip Squamous Cell Carcinoma

Objective: To evaluate the expression through immunohistochemistry of galectins -1, - 3 and -7 in cases of lip squamous cell carcinoma (SCC) in association with clinical data and morphological parameters proposed by Bryne (1998). Material and Methods: Thirty paraffin-embedded SCC cases were submitted to histological sections. Two independent pathologists performed the analysis of galectins -1, -3 and -7 through light microscopy evaluating the presence or absence of marking and intensity. The expressions of these proteins were submitted to statistical analysis (chi-square test, Fisher's exact test and Binomial test for the comparison of proportions). Results: Positive expression of galectins -1 and -3 was observed in 93.3% and 43.3% of cases, respectively. However, there was no statistically significant association between these proteins and the clinical variables used. Galectin-7 immuno-expression was present in all cases evaluated and showed statistical significance between marked cell type (parenchyma cells) and regional metastasis and between marked cell type (parenchyma cells) and histological gradation. Conclusion: Changes in the galectins -1, -3 and -7 expression suggest the participation of these proteins in the regulation of cellular functions and that the immuno-expression of these proteins can act as a marker of the biological behavior of lip squamous cell carcinoma.

Ética, bioética y método clínico en el tratamiento de pacientes pediátricos aquejados de migraña / Ethics, bioethics and clinical method in the treatment of pediatric patients suffering from migraine

La migraña es una de las enfermedades que ha acompañado al hombre a lo largo de la vida. Con el objetivo de argumentar, mediante la recopilación de resultados de estudios clínicos de evidencias, la relación existente entre la ética médica y el método clínico en el tratamiento de migrañas en pacientes pediátricos, se realizó revisión de bibliografías sobre migraña, y algunos aspectos del cumplimiento de la ética médica y el método clínico, los que fueron considerados en el desarrollo de las consultas e interconsultas de Neurología del Hospital Pediátrico Universitario “William Soler”, incluyendo las consultas de Proyección Comunitaria del municipio de Boyeros, en La Habana, en los últimos 10 años. Se accedió a las bases de datos PubMed, Lilacs, Scielo y Google, se restringió la búsqueda por temática y para los últimos 10 años, así como estudios de evidencia, cuyas bases de datos se obtuvieron de las consultas y los resultados fueron publicados en revistas. Se exponen trabajos de evidencia relacionados con el tratamiento de la migraña, en los cuales se aprecia la comunión existente entre la Ética y el método clínico. Las evidencias demostradas en las publicaciones de la autora principal de este estudio sobre el tratamiento de la migraña en Pediatría, demuestran que se puede cumplir con la ética médica y el método clínico, apuntes de Hipócrates antes de nuestra era.

Migraine is a disease that has accompanied man throughout the life. With the objective of substantiating through the collection of results from clinical studies of evidence the relationship between the medical ethics and the clinical method in the treatment of migraine in pediatric patients, a literature review on migraine and on some aspects of the compliance with the medical ethics and the clinical method was made. These aspects had been considered in the medical consultation and interconsultation service of neurology in “William Soler” university pediatric hospital including the consultation service of the Community Project in Boyeros municipality in Havana in the last ten years. PubMed, Lilacs, Scielo and Goggle databases were accessed; search by topic and restricted to the last ten years was made as well as evidence-based studies whose databases were created from consultations, and the results were published in journals. Evidence papers related to the treatment of migraine were presented, in which the communion between ethics and the clinical method was reflected. The evidence shown in the publications of the main author of this study on the treatment of migraine in pediatrics prove that the medical ethics and the clinical method should be complied with, as Hippocrates said before the CE.

Extensa dissecção coronária espontânea com boa evolução clínica mantida sob tratamento conservador / Extensive spontaneous coronary dissection with favorable evolution maintained under conservative treatment

A dissecção coronária espontânea é uma entidade rara e, por conseguinte, de etiologia, fisiopatologia e tratamento ainda não estabelecidos. Acomete, em geral, mulheres jovens, sem os clássicos fatores de risco cardiovascular, comumente ao longo do ciclo gravídico-puerperal. Vários fatores influenciam na estratégia de tratamento, como quadro clínico, status hemodinâmico, topografia da dissecção, número de artérias afetadas e fluxo coronário distal. Como no caso relatado, em pacientes estáveis, com dissecções bem delimitadas e, sobremodo, quando o fluxo coronário é reestabelecido, pode-se optar por uma abordagem conservadora, em razão da alta incidência de resolução espontânea e da baixa incidência de eventos adversos a longo prazo

Spontaneous coronary dissection is a rare entity and, therefore, its etiology, pathophysiology, and treatment are not yet established. It affects mainly young women without the classic cardiovascular risk factors, commonly during the pregnancy-childbirth cycle. Several factors influence the treatment strategy, such as clinical presentation, hemodynamic status, topography, number of affected arteries, and distal coronary flow. As in the reported case, in stable patients with well-defined dissections and mainly when the coronary flow has been re-established, one can choose a conservative approach, due to the high incidence of spontaneous resolution and low incidence of long-term adverse events

La presentación de la ureasa en forma líquida es uno de los elementos que hacen más sencillo este proceso, de fácil y rápida ejecución con resultados confiables. OBJETIVO: desarrollar una solución de ureasa estable, como componente del juego de diagnosticador de urea en suero. MÉTODOS: se diseñó y optimizó la formulación teniendo en cuenta: la concentración de la enzima, las soluciones buffer, los preservos y los compuestos orgánicos polihidroxilados para lograr un producto en forma líquida estable. Se evaluó la especificidad, precisión, linealidad, exactitud (comparación de métodos) y la sensibilidad del método; así como la estabilidad en vida de estante de 2 a 8 °C, por un período de 18 meses. RESULTADOS: se logró un reactivo líquido estable (> 12 meses de 2 a 8 °C), donde el método analítico resultó ser específico y lineal hasta 30 mmol/L de urea (r2= 0,999), sensible, preciso coeficiente de variación, CV< 3 por ciento) y exacto (r 0,999), satisfactorio para el uso al que se destina el producto, con calidad analítica comparable con los existentes en el mercado. CONCLUSIONES: el desarrollo de la formulación de ureasa líquida estable, permitirá introducir este componente esencial, en el juego de reactivos de urea que oferta la Industria Nacional al Sistema de Salud de acuerdo con los requisitos vigentes (Reg. 8-2001) para su comercialización(AU)

INTRODUCTION: determination of serum urea has great importance for the clinical diagnosis of several renal illnesses. The most implemented methods involve the use of the urease enzyme because of its high specificity for this analyte hydrolysis; the Berthelot method uses urease in the first reaction step followed by colorimetric reaction of the released ammonium. The presentation of urease in liquid form is one of the elements that make this process simpler, of easy and fast application with reliable results. OBJECTIVE: to develop a stable urease solution as part of the diagnostic set for serum urea. Methods: THE ADEQUATE FORMULATION WAS DESIGNED AND OPTIMIZED BY TAKING INTO account the enzyme concentration, the buffer solutions, the preserves and the polyhydroxyled organic compounds to attain a final stable liquid product. The parameters called specificity, precision, linearity, accuracy (comparison of methods) and sensitivity of the method were all evaluated in addition to the shelf life at 2 a 8 °C for 18 months. RESULTS: astable liquid reagent (over 12 months at 2 a 8 °C ) was reached; the analytical method proved to be specific and linear up to 30 mmol/L of urea (r2= 0,999), sensitive, precise, with variation coefficient lower than 3 percent and accurate ((r 0,999), satisfactory for the intended use of the product and the analytical quality comparable to that of the already existing products. CONCLUSIONS: the development of the stable liquid urease formulation will allow introducing this essential component in the reagent set for urea offered by the national industry to the healthcare system according to the requirements for commercialization (Reg 8-2001)(AU)
