Revista Cubana de Medicina , 2004,
Abstract: La fibromialgia es uno de los síndromes reumáticos más comunes, caracterizado por dolores musculoesqueléticos y puntos dolorosos sin existir sinovitis ni miositis. Se estudiaron 20 pacientes con diagnóstico de fibromialgia para conocer, mediante la prueba ergométrica, las alteraciones del sistema nervioso autónomo. Se observó, en el grupo control, un incremento normal de la frecuencia al adoptar el ortostatismo lo cual refleja activación del sistema simpático, mientras que en las pacientes con fibromialgia no existió dicho reflejo. Se comprobó incremento adecuado de la tensión arterial en el 87 % de las pacientes con fibromialgia, infradesnivel del ST mayor de 1 mm en el 20 % de las pacientes, ausencia de arritmia y síntomas de cardiopatía en todas las pacientes y disminución de la capacidad física en 4.Se concluyó que las pacientes con fibromialgia presentan una disfunción del sistema nervioso autónomo. Fibromyalgia is one of the commonest rheumatic symptoms, characterized by musculoskeletal pain and painful points with neither synovitis nor myositis. 20 patients with diagnosis of fibromyalgia were studied to know the alterations of the autonomous nervous system by the ergometric test. In the control group, it was observed a normal increase of frequency on adopting orthostatism, which reflects the activation of the sympathetic system. This reflex did not exist among the patients with fibromyalgia. An adequate rise of the arterial pressure in 87 % of the patients with fibromyalgia, an infraunevenness of the ST over 1 mm in 20 % of the patients, an absence of arrhytmia and symptoms of heart disease in all patients, and a reduction of physical capacity in 4, were proved. It was concluded that patients with fibromyalgia present a dysfunction of the autonomous nervous system.

Revista Cubana de Medicina , 2004,
Abstract: Se presentaron 4 casos de carcinoma papilar quístico en el período de 4 a os. Se realizó examen físico de todos los casos; se encontró una masa cervical firme en la cara anterior del cuello y en 2 de ellos, se palparon adenopatías cervicales. Se aplicaron técnicas de imagen (ecografía cervical y gammagrafía tiroidea); se completó el estudio con BAAF, que tuvo valor diagnóstico en el 75 % de los casos. Se realizó un estudio anatomopatológico de todas las piezas obtenidas. Se hizo la resección del quiste, biopsia intraoperatoria y si se confirmó el diagnóstico de carcinoma papilar quístico, se le realizó una tiroidectomía total y si fue necesario, linfadenectomía. Se completó el tratamiento con I131 a dosis ablativa y tratamiento hormonal supresor de la TSH. Se destacó el papel de la BAAF en el estudio preoperatorio. 4 cases of cyst papillary carcinoma in a period of 4 years were presented. All of them underwent physical examination. A firm cervical mass was found in the anterior side of the neck and cervical adenopathies were palpated in 2 of them. Imaging techniques (cervical echography and thyroid gammagram) were applied. The study was completed with FNAB, which had a diagnostic value in 75 % of the cases. An anatomopathological study of all the pieces obtained was conducted. Resection of the cyst and intraoperatory biopsy were performed. In those cases with confirmed diagnosis of cyst papillary carcinoma, total thyroidectomy was carried out and, if necessary, lymphadenectomy. The treatment was concluded with I131 at ablative doses and TSH -supressing hormonal treatment. The role of FNAB in the preoperative study was stressed.

Abstract: Se estudiaron 40 pacientes del sexo femenino, premenopáusicas, menores de 45 a os, con diagnóstico establecido de artritis reumatoidea según criterios del Colegio Americano de Reumatología y todas con tratamiento de esteroides, con un equipo de densitometría ósea por ultrasonido del calcáneo. Al analizar el promedio de t-score (como marcador de osteoporosis), encontramos que el valor más bajo de fue de - 4,5 y el máximo de -1,5. Se empleó el test estadístico t -Student para comparar los promedio del t-score según: dosis, tiempo de tratamiento con esteroides y tiempo de evolución de la enfermedad. Se encontró osteoporosis en 23 pacientes que tomaban más de 20 mg de esteroides; en 27 con más de 5 a os de tratamiento con esteroides; y en 23 con más de 5 a os de evolución de la enfermedad. Al explorar el antecedente de fractura y relacionarlo con el tiempo de tratamiento y la dosis de esteroides encontramos que 9 pacientes (81,8 %) con más de 5 a os de tratamiento y 6 (54,5 %) con más de 20 mg de esteroides tienen antecedente de fractura. 40 premenopausic female patients under 45 with established diagnosis of rheumatoid athritis according to the criteria of the American College of Rheumatology were studied.

Abstract: Se estudió un grupo de 52 mujeres en etapa premenopáusica con diagnóstico de bocio tóxico difuso y un grupo control constituido por 54 mujeres sanas. Se encontró que la media para la edad en el grupo 1 fue de 35,7 a os y para el grupo 2, de 34,83 y la media en las 106 pacientes fue de 35,29 a os. Se midió la densidad mineral ósea mediante un equipo de densitometría ósea por ultrasonido del calcáneo (SONOST 2000 Medison). Se evidenció que el número de casos sin alteración ósea fue mayor en el grupo control: 40 casos (74,0 %), contra 8 (15,4 %) del grupo 1, y este grupo tuvo el mayor porcentaje de casos con osteopenia (22 [42,3 %]) y osteoporosis (22 [42,3 %]). Al utilizar estudios no paramétricos como el test de Rangos con signos de Wilcoxon encontramos que existe diferencia significativa entre el estudio inicial y el final, según los resultados de la osteosonometría. La osteosonometría fue normal al a o del tratamiento en 19 pacientes por encima de la realizada inicialmente, y la osteoporosis desapareció en 10 pacientes. Se halló que los 16 que se mantuvieron hipertiroideos al realizarle el estudio final de osteosonometría, presentaban osteopenia u osteoporosis. Mientras que en los 25 pacientes eutiroideos la osteosonometría fue normal. Al final, 27 sujetos tuvieron un resultado en la osteosonometría en el rango normal, 19 por encima del estudio inicial. En los sujetos a los que se les aplicó el esquema de tratamiento 3, en 15 la osteosonometría fue normal, así como que fue el grupo que menos pacientes osteoporóticos tuvo, con 2 solamente, aunque con el tratamiento 2 la respuesta fue bastante adecuada, no así con el tratamiento 1 2 women in premenopausal stage diagnosed as diffuse toxic goiter and a control group including 54 healthy women were studied.

Abstract: a cross-sectional descriptive study of 340 persons assigned to two groups, with and without family history of diabetes mellitus type 2 (dm2), was carried out. the objective was to detect whether those persons with family history of dm2 had more hyperinsulemia, metabolic syndrome, associated cardiovascular risk factors and target organ lesions, expressed in left ventricle hypertrophy, than subjects without diabetes family history. the result was that hyperinsulemia was present in 96 patients with family history of dm2 (56,5 %) and significance level of p= 0,001. metabolic syndrome was more frequent in subjects with family history of dm2 (90) for 52,9 % of cases and p= 0,000. hypertriglyceridemia was both the most noticeable marker of the metabolic syndrome and the most statistically significant risk factor in subjects with family history of dm2 (96 , 52,9 % of cases and p= 0,000). left ventricle hypertrophy was associated as target organ lesion expression to subjects with family history of dm2 (36: 21,2 % and p=0,043). it was concluded that subjects with family history of dm2 are more likely to have hyperinsulinemia, metabolic syndrome, cardiovascular risk factors and target organ lesions than those persons without such a family history of dm2.

Abstract: An important issue was raised for discussion trough the last decade regarding the meaning of brand equity. Different forms of analysis and estimation criteria have been applied, and that is the reason for the current ambiguity on its meaning. In this article, we present a theoretical frame were several forms of study and criteria for brand equity estimation are empirically analysed. Using six different brands of training shoes, seven estimation variables are empirically analysed in accordance with the opinions given by a sample of users for these different brands. By means of this analysis, it is our aim to contribute to a better knowledge on he concept of brand equity.
