El programa educativo constó de 18 sesiones grupales de dos horas de duración cada una, se utilizaron metodologías participativas como demostraciones, visitas, sociodramas, simulaciones, discusión de grupos y representaciones, entre otras, a cargo de un equipo multidisciplinario. El estudio se realizó con 36 adultos diabéticos tipo II, sin complicaciones crónicas de la enfermedad, los cuales se dividieron en dos grupos: 19 en el grupo experimental, quienes recibieron la intervención educativa y 17 conformaron el grupo control, quienes recibieron el tratamiento tradicional de atención ambulatoria. La dieta se evaluó en ambos grupos al inicio y al final del proceso educativo, utilizando el registro de consumo de tres días y la frecuencia de consumo de alimentos. Inicialmente en ambos grupos el consumo energético fue adecuado: al final del proceso, únicamente el grupo intervención redujo significativamente el contenido de grasas totales, ácidos grasos saturados, energía y colesterol de la dieta. En este mismo grupo, se evidenció el cambio en el tipo y cantidad de grasa utilizada en la cocción de los alimentos, se redujo en 10% el consumo diario de manteca y se incrementó el de aceite en 13%, contrario a lo sucedido en el grupo control. Los pacientes intervenidos redujeron el consumo de azúcar simple de 30% a 10%, mientras que en el grupo control aumentó en 5% al final del estudio. Se logró reorganizar los horarios de comidas, el espaciamiento entre las mismas y la consistencia de los diferentes tiempos de comidas, los cuales disminuyeron de un promedio de 5,3 a 4,8 al día. Como resultado de lo anterior, el grupo intervención perdió más peso que el grupo control, normalizó la glicemia y la hemoglobina glicosilada alcanzó valores deseables. El perfil lipídico se mantuvo en rangos aceptables.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>This article reports the findings of a nontraditional educational intervention program on the modification of dietary practices in Diabetes Mellitus Type II patients in an urban community in Costa Rica. The educational program consisted of 18 sessios, each one of a duration of two hours, using participate methods as demostrations, visits, sociodramas, mimic, discussion of groups and role playing. The topics were developed by a multidisciplinary team and included general aspects of the illness as well as self control and daily dietary practices. All the sessions were conducted in groups. A written diet was not distributed to particpants, so that modifications would be implimented throuhout the duration of the intervention. The study population consisted of 36 adults, diabetics type II, without chronics complications of the illness. They were divided into two groups: in the experimental group 19 diabetics received the educational intervention and in the control group, 17 which did not receive the intervention. Diet was evaluate in both groups at the beginning and the end of the educational program usign the food record and frequency of intake of foods. The following are the primary findings: The diet was adequate in respect to energy intake in both grups. At hte end of eighth month, diet in the experimental group had significantly decreased in the amount of total and saturated fats, energy and cholesterol. We observed, moreover, the change in the type of fats used for cooking. The experimental group, had un decreased of 10% of the daily intake of palm oil and increased the use of unsaturales oil by13%, which was contrary to the control group. In the same group simple sugar decreased 30% to 10%, while in the control group this increased 5% at the end of the educational process. Eating schedules, the duration between meals and the variability of foods, were reorganized. The recipes were modified by the participants, we observed change in the foods using. Because of this, the experimental group lost more weight than the control group, glicemic levels were normalized and glycoside Hemoglobin reached at desirable values. The lipis (choleterol, Triglycerides, HDL, LDL) were within and acceptable range.</p></abstract>

La técnica consiste en mezclar 2,0 mL de reactivo de trabajo previamente preparado, con 20 µ L de suero. La absorbancia es leída a 500 nm contra blanco de reactivos después de 15 minutos de incubación a 37º C. El intervalo analítico es de 25 a 600mg/dL. La comparación de los resultados con el método de colesterol total en suero por extracción dio una regresión lineal de Y = -0,4223 + 0,8907(X), con un coeficiente de correlación (r) de 0,958 y una desviación estándar sobre la línea de regresión (Sy/x) de 24 mg/dL. Con el método Colesterol Fast Color se obtuvo una regresión lineal de Y = 19,5 + 1,02 (X), un coeficiente de correlación (r) de 0,972 y una desviación estándar sobre la línea de regresión de 13 mg/dL. Con el método Colestat la regresión lineal fue de Y = 25 + 1,000 (X) con un coeficiente de correlación (r) de 0,983 y una desviación estándar sobre la línea de regresión lineal de 16 mg/dL. Las precisiones día a día para muestras con valores de colesterol bajos, normales y altos mostraron coeficientes de variación de 1,8; 1,9 y 1,5 por ciento y en un mismo día de 2,3; 3,3 y 2,4 por ciento respectivamente. La hemoglobina y el ácido acetilsalicílico en concentraciones de 50 mg/dL no bilirrubina produce una interferencia de 0,42 por ciento. El reactivo de trabajo almacenado en botella ámbar es estable por al menos 3 semanas a 2- 8º C. El reactivo es estable por lo menos un año si la solución concentrada de enzimas se almacena en congelación a -70º o en forma liofilizada, y por al menos dos meses a + 4° C. Las concentraciones óptimas incluyen 1,5 mmol/L de 4-aminofenazona, 0,5 g/L de Triton X-100, 3 mmol/L de colato de sodio, 16 m mol/L de fenol, 1000 U/L de peroxidasa, 250 U/L de colesterol oxidasa y 500 U/L de colesterol esterasa.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>A colorimetric method based on the Trinder reaction for use in enzymatic determination of serum cholesterol is evaluated. Two mL of working reagent, previously prepared, is mixed with 20 µK if serum and the absorbance is read against blank reagent at 500nm, after 15 minutes of incubation al 37º C. The analytical range is 25 to 600 mg/dL. Comparisons of results with total serum cholesterol by extraction gave a linear regression of Y= -0.4223 + 0.8907 (X), with a correlation coefficient (r) of 0.958 and a standard error (Sy/x) of 24 mg/dL. Comparisons with results by Colesterol Fast Color gave a linear regression of Y= 19.5 + 1.02 (X), a correlation coefficient (r) of 0.972 and a standard error (Sy/x) of 13 mg/dL and comparisons with results by Colestat gave a linear regression of Y = 19.5 + 1.02(X), a correlation coefficient (r) of 0.972 and standard error (Sy/x) of 13 mg/dL. Hemoglobin and acetylsalicylic acid do not interfere up to 50 mg/dL. L-ascorbic acid interferes equimolecularly and one mg/dL of bilirrubin causes and interference of 0.42 percent. The working reagent, stored in an amber-colored bottle, is stable for at least 3 weeks at 2-8º C. The reagent is stable for at least one year if the concentrated enzime solution is stored lyophilized or at -70º C, and ofr at least twomonths al +4º C. The optimun reagent concentration includes 4-aminophenazone 1,5 mmol/L, Triton X-100 0.5 g/L, sodium cholate 3,0 mmol/L potassium ferrocyanide 16 µmol/L, phenol 15 mmol/L, peeroxidase 1000 U/L, cholesterol oxidase 250 U/L and cholesterol ester hydrolase 500 U/L.</p></abstract>

La tinción de Gram ha sido usada para el diagnóstico de VB, asignando un puntaje a los parámetros más reproducibles (Bacilos Gram positivos, Gram negativos y bacterias curvas). Se analizó la presencia de VB en 105 prostitutas, mediante la tinción de Gram. El 65% presentaron VB, de ellas el grupo de menores de 40 años presentó la mayor frecuencia de contactos sexuales (&gt;10/semana) y la mayor prevalencia de VB. El hallazgo de bacterias curvas Gram negativas tiene mayor valor predictivo que la observación de bacilos Gram negativos, pues sólo los primeros correlacionaron estadísticamente con el diagnóstico de VB. Estos datos resaltan la importancia de la tinción de Gram como un método económico y útil para el análisis de VB.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>Bacterial vaginosis (BV) is an alteration of the vagina, where normal microflora are replaced by non-Lactobacillus bacteria; also, common findings under these conditions are: presence of sticky white discharge with a pH &gt; 4,5, test for amines and clue cells are positive. Gram stain of vaginal secretions scoring (0 to ++++); has been used to iagnose of BV the most reliab le morphotypes found in those secretions are: Gram-positive straight rods (Lactobacillus morphotype), Gram negative pleomorphic rods (Gardnerella morphotype), and Gram-negative curved bacteria (Mobiluncus morphotype). The prevalence of BV in 105 prostitutes from San José, Costa Rica, was analysed using there criteria: 65% were positive for VB. The group less than 40 years of age had more sexual contacts (&gt;10/week) and the highest prevalence of BV. The finding of curved Gram-negative rods has more predctive value than the observation of Gram-negatives straigth bacilli (Gardnerella morphotypes), because only the former was singnificantly associated with B.V. These data enhace the relevance of use the Gram stain of vaginal discharge for diagnosis of BV.</p></abstract>

El tamaño d elamuestra se determinó de acuerdo con la fórmula n= z2pq/d2 y la frecuencia alélica por el método de ocnteo de genes. La distribución obtenida para el fenotipo Jk (a+b-) es de 27,4% para el Jk(a+b+) es de 52,6% y para el Jk(a-b+) es de 20,0%, muy semejante ea la establecida por Gaenssien y col. En la población hispana de los Estados Unidos. Para el gen Jka encontramos una frecuencia de 0,5372 y para el JKb de 0,4627. Por Chi cuadro se determinó que la población estudiada se encuentra en equilibrio de Hardy Weinberg.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>Eight hundred and seventy two (872) blood samples from different parts of Costa Rica were tested at the Forensic Science Laboratory (OIJ), Costa Rica, to establish Kidd system phenotype and genotype distribution within the country. The study found 27.4% Jk (a+b-), 52.6% Jk (a+b+) amd 20.0% JK (a-b+), with an allelic distribution of 0.537 for Jka and 0.463 for Jkb. Sample size was determined with the formula n= z2 pq/d2 and allelic frequency by the gene counting method. Based on the Chi square method value with 2 degrees of freedom and a 99% confidence interva, there was no significant deviation (p below 0.01) on the expected values resulting from the Hardy Weinberg equilibrium assumptions.</p></abstract>

Como neoplasia ovárica, es infrecuente, ya que apenas conforma el 0,2-0,5% de todas ellas, pero ante un cuadro de androgenización, e suno de los diagnósticos principales por considerar, sobre todo en mujeres jóvenes. Afortunadamente, lamayoría tienen uncomportamiento clínico benigno y se detectan en estadíos iniciales, lo que permite unmanejo quirúrgico conservador, con buen pronóstico y sobrevida.

<abstract abstract-type="short" xml:lang="en"><p>The most frequent virilizing tumors of the ovary are Seroli-Leydig cell tumors (SLCT). Although rare, accounting for only 0.2-0.5% of all ovarian neoplasms, SLCT is one of the main differencial diagnoses when there is androgenization, especially in young women. Most behave clinically as low-grade malignancies and are detected in early stages, which allow a conservative surgical treatment, usually with good prognosis and survival rates. In this article, two typical cases of SLCT with virilization syndrome are described and discussed, along with a brief literature review.</p></abstract>
