Bocio,función tiroidea y excreción de yodo en gestantes de la zona de El Bierzo

Estudios publicados en el año 1993 demuestran alta incidencia de bocio en escolares de la zona de El Bierzo.Hemos valorado mediante encuesta el consumo de sal yodada, la presencia de bocio mediante palpación y ecografía, la función tiroidea midiendo concentraciones hormonales en plasma y la excreción de yodo en orina y leche mediante el método de Benotti, en un grupo de mujeres embarazadas de la zona, en los tres trimestres de la gestación y en el posparto.Nuestros resultados demuestran escaso consumo de sal yodada, endemia bociosa grave, hipotiroxinemia materna, pobre excreción de yodo en orina en las gestantes y escasa presencia de yodo en la leche materna. Todo ello indica la necesidad de campañas institucionales para remediar la situación.     

¿Existe mayor riesgo de diabetes gestacional en pacientes con disfunción tiroidea autoinmune?

ObjectiveSome recent studies have related autoimmune thyroid dysfunction and gestational diabetes (GD). The common factor for both conditions could be the existence of pro-inflammatory homeostasis. The study objective was therefore to assess whether the presence of antithyroid antibodies is related to the occurrence of GD.Material and methodsFifty-six pregnant women with serum TSH levels ≥ 2.5 mU/mL during the first trimester were retrospectively studied. Antithyroid antibodies were measured, and an O'Sullivan test was performed. GD was diagnosed based on the criteria of the Spanish Group on Diabetes and Pregnancy.ResultsPositive antithyroid antibodies were found in 21 (37.50%) women. GD was diagnosed in 15 patients, 6 of whom (10.71%) had positive antibodies, while 9 (16.07%) had negative antibodies. Data were analyzed using exact logistic regression by LogXact-8 Cytel; no statistically significant differences were found between GD patients with positive and negative autoimmunity (OR = 1.15 [95%CI = 0.28-4.51]; P = 1.00).ConclusionsThe presence of thyroid autoimmunity in women with TSH above the recommended values at the beginning of pregnancy is not associated to development of GD. However, GD prevalence was higher in these patients as compared to the Spanish general population, suggesting the need for closer monitoring in pregnant women with TSH levels ≥ 2.5 mU/mL.     

Asociación de polimorfismos en el gen FTO con la obesidad mórbida en la población extremeña

ObjectiveTo select individuals whose morbid obesity can be attributed mainly to their individual genetic profile. After excluding patients with potential monogenic syndromes or diseases associated with obesity, we evaluated the association of the single nucleotide polymorphisms (SNPs) rs1861868 and rs9939609 of the fat-mass and obesity-associated FTO gene with an inherited predisposition to morbid obesity.Patients and methodsWe evaluated 270 patients with morbid obesity and onset before the age of 14 years and selected 194 due to their phenotypes and family history; 289 control individuals were included. The rs1861868 and rs9939609 variants, located in the FTO gene, were genotyped. Genotype and haplotype frequencies were compared between cases and controls.ResultsThe A allele of rs9939609 was associated with severe obesity starting in childhood among the Spanish population. The rs1861868 G/rs9939609 A haplotype of the FTO gene was also significantly associated with severe obesity in our population, with an odds ratio of 3.03 (95% confidence interval, 1.74–5.27).ConclusionAnalysis of the genetic basis of obesity requires rigorous selection of cases. In this study, the association of the rs9939609 SNP with obesity widely described in distinct populations was confirmed among overweight Spanish children. Genotyping rs1861868 allowed us to identify the first risk haplotype in the FTO gene, which is located in the adjacent haplotype block containing rs9939609. In-depth study of the variability of the FTO gene is essential to define its deleterious capacity.     

Utilización del POMA en nuestro medio para la valoración del equilibrio y la marcha en una población de personas mayors residentes en la comunidad

Objectivesto study the balance and the gait by the Performance Oriented Mobility Assessment (POMA) in the population of people ≥ 65 years in function of age, gender; relation with the capacity to develop the activities of daily living, physical exercise, perception of health and previous falls.Material and methodsWe study a cohort of 443 people, 262 women and 181 men, representative of the population ≥ 65 years, resident in the community and able to walk from the city of Mataró. The evaluation was made with the 22 items POMA. Basic and instrumental activities of the daily life (Katz Index and Lawton), physical activity, health perception (Iowa test) were also assessed.Results29.3% of subjects did not present abnormalities in any of the items, 22.6% presented one abnormality, 12.4% two, and 35.7% three or more. 35.9% and 50.2 of subjects did not present abnormalities in the static and dynamic components respectively. Women had greater number of abnormalities than men (42.0% vs 20.6%) for the global and also for each of the two components (static and dynamic) (p < 0.0001). The number of abnormalities increased significantly with age, specially on those 75 years and older (p < 0.0001). A greater number of errors was correlated with less independence on the basic and instrumental activities of daily living, with less physical activity, health perception and with antecedents of previous falls.     

Impacto asistencial tras la introducción de la ecografía tiroidea en una unidad monográfica de atención al nódulo tiroideo

IntroductionWorldwide incidence of thyroid cancer has increased in recent decades.ObjectiveTo provide evidence of the diagnostic and care efficiency of a monographic thyroid nodule clinic integrating clinical examination, ultrasound examination, and cytology with on site evaluation.Patients and methodsPatients attending the monographic thyroid nodule clinic from January 2004 to June 2010. Two periods may be distinguished based on availability of ultrasound equipment at the time of the visit: a first period (P1: 01/2004-09/2007) where no ultrasound equipment was available at the clinic and FNA by palpation was performed, and a second period (P2: 10/2007-06/2010) where this equipment was available and ultrasound-guided FNA was performed.ResultsA total of 1036 patients [P1: 537 (52%), P2: 499 (48%)] were seen and enrolled.Diagnostic efficiency (P1 vs P2): 143 vs 181 patients were seen annually, p < 0.001; FNA number/nodule: 1.68 vs 1.17, p < 0.001; percent FNAs with inadequate material: 26% vs 5.3%, p < 0.001; mean (SD) nodule size: 23.6 (12.4) vs 21.7 (11.7) mm, p 0.040; proportion of nodules examined less than 10 mm in size: 9.9% vs 13.7%, p 0.030.Care efficiency: mean time (range) from the first visit to surgery indication: 332 (0-2177) vs 108 (0-596) days, p < 0.001; proportion of patients referred for surgery due to suspect cytology/other reasons: 1.06 vs 2.21, p < 0.001; and operated benign neoplasm/pathology: 0.47 vs 0.93, p = 0.002.ConclusionA monographic thyroid nodule clinic integrating clinical examination, ultrasound, and cytology evaluated on site increases diagnostic and care efficiency in patients with thyroid nodules.     

Estado actual de la población indígena y mestiza en Argentina

This article describes the usage of every day forms of obscene joking among primarily working‐class women in a small town in Sweden. The author considers obscenity as symbolically related to the sometimes painful, sometimes absurd experiences of sexuality and bodily functions, andas an expression for and a means of coping with the incongruities of social life. Through the form of humor, obscenity becomes a subtle and complex means of cultural and social critique. This also creates a sense of community among the women who engage in the obscene joking.
