ABSTRACT

OBJECTIVE: To study the relationship between certain aspects of puberal development in a group of women with primary congenital hypothyroidism diagnosed before the introduction of neonatal screening programs and in a control group of healthy women. PATIENTS AND MEASUREMENTS: Longitudinal retrospective study of 15 women with primary congenital hypothyroidism and 26 healthy women. Height, chronological and bone age, and growth velocity are expressed in centimeters and centimeters per year, respectively. Bone age was analyzed by the Greulich and Pyle atlas. Bone and chronological age are expressed in decimal year. Statistical data were expressed as the means and as the maximum and minimum standard deviations. The Student-Fisher t-test was used to compare the two groups. RESULTS: 1. Evolution of mean height measurements in the hypothyroid and control group respectively were as follows: 154.565.11 and 156.465.28 for genetic height; 140.065.21 and 138.965.95 in tanner's B2, and 153.763.32 and 155.065.93 at menarche. Final height was 157.863.71 and 158.965.95. The difference between final and genetic height was 3.2564.17 and 2.1664.18. The increase in height after menarche was 4.1261.61 and 3.9261.81. The total increase in height during puberty was 17.7464.32 and 20.4665.30. The percentage of height reached during puberty compared with final height was 11.2462.70 and 12.8263.18. 2. Evolution of mean chronological age was respectively: 11.5761.01 and 10.7561.36 in tanner's B2 P=0.05); 13.48+/-0.88 and 13.18+/-1.12 at menarche, and 16.25+/-1.33 and 14.91+/-1.12 at reaching final height (p=0.01). Time between Tanner's B2and B3, B3and B4and B2and B4were 0.61+/-0.23and 0.98+/-0.60 (p=0.01), 0.71+/-0.33and 0.70+/-0.33, 1.32+/-0.51 and1.65+/-0.70. Time between B2and menarche was 1.92+/-0.55 and 2.46+/-1.05(p=0.05) and between menarche and final height was 2.89+/-1.04 and 1.70+/-0.63 (p=0.001). 3. Evolution of mean bone age measurements was respectively: 10.57+/-1.51 and 10.67+/-1.26 in Tanner's B2, and 13.600.97 and 13.27+/-0.65 at menarche. Development of bone age between Tanner's B2 and B3, B3 and B4 and B2and B4was 1.02,0.60 and 0.91,0.65, 1.12,0.76and 0.96+/-0.59, and 2.13+/-1.29 and 1.74+/-1.04, respectively, and between B2 and menarche it was 3.17+/-1.25 and 2.66+/-1.38.4. Mean growth velocity in real time elapsed between different intervals and in centimeters per year was as follows: between B2 and B3:.05+/-2.09, 5.75+/-2.80 and 8.40+/-1.80, 6.24+/-1.74(p=0.01); between B3 and B4: 4.74+/-1.54, 4.97+/-2.82 and 7.31+/-2.14, 7.14+/-1.68; between B2 and B4: 7.40+/-3.70,0.90+/-4.13 and 7.40+/-2.18, 6.75+/-1.34 and between B2and menarche: 13.62+/-4.41, 15.96+/-5.42and 7.20+/-1.57, 6.90+/-1.27 respectively. CONCLUSIONS: In women with hyperthyroidism puberty was normal, except that onset was delayed, development was faster and the postmenarche growth period was longer than in the control group. Bone maturation and growth velocity were similar in both groups, and both of them reached a normal final height compared with their target height.

ABSTRACT

OBJETIVO: Estudiar diferentes aspectos del desarrollo puberal de mujeres afectadas de hipotiroidismo congénito primario diagnosticadas clínicamente, comparando con un grupo control de referencia. PACIENTES Y MÉTODOS: Estudio retrospectivo, longitudinal, formado por 15 pacientes hipotiroideas y 26 normales. Se han valorado diferentes parámetros, como la talla, la edad cronológica y ósea, y la velocidad de crecimiento a lo largo de su desarrollo puberal. Las tallas y las velocidades de crecimiento se han expresado en centímetros y centímetros por año, respectivamente. Las edades óseas se han analizado mediante el atlas de Greulich y Pyle. Las edades cronológicas y óseas se han expresado en años con sus fracciones decimales. Los estadios puberales se han definido según los criterios de Tanner. Los datos estadísticos se presentan como media, desviación standar y máximos y mínimos. Ambas poblaciones se han comparado mediante la prueba de la T de Student-Fisher. Se ha considerado un nivel de significación estadístico cuando se obtenía una p=0,05. RESULTADOS: 1.La evolución de las tallas medias de la población hipotiroidea y control fueron respectivamente las siguientes. Talla genética, 154,5 ± 5,11 y 156,4 ± 5,28. En T2, 140,0 ± 5,21y 138,9 ± 65,95. Al presentar la menarquia, 153,7 ± 3,32 y 155,0 ± 5,93. Sus tallas finales fueron de 157,8 ± 3,71y 158,9 ± 5,95. La diferencia entre la talla final y la genética fue de 3,25 ± 4,17y 2,16 ± 4,18. El incremento de talla tras la menarquia fue de 4,12 ± 1,61 y 3,92, ± 1,81. La ganancia total de talla en la pubertad de 17,74 ± 4,32y 20,4 ± 5,30. El porcentaje de talla alcanzado en la pubertad respecto a la talla final de 11,24 ± 2,70y 12,82 ± 3,18.2. La de las edades cronológicas medias fue respectivamente de 11,57 ± 1,01y 10,75 ± 1,36 en T2 (p=0,05), de 13,48 ± 0,88y 13,18 ± 1,12 al presentar la menarquia, y de 16,25 ± 1,33 y 14,91 ± 1,12 al alcanzar la talla final (p=0,01). El tiempo transcurrido entre los estadios T2 yT3, T3 y T4, y T2 y T4 fue de 0,61 ± 0,23 y 0,98 ± 0,60 (p=0,01), de 0,71 ± 0,33 y 0,70 ± 0,33 y de 1,32 ± 0,51y 1,65 ± 0,70. El transcurrido entre T2 y la menarquia fue de 1,92 ± 0,55 y 2,46 ± 1,05 (p=0,05) y entre la menarquia y la talla final de 2,89 ± 1,04 y 1,70 ± 0,63 (p=0,001). 3. La evolución de las edades óseas de ambas poblaciones fue respectivamente de 10,57 ± 1,51 y 10,67 ± 1,26 en T2, y de 13,60 ± 0,97y 13,27 ± 0,65 al presentar la menarquia. El avance de la edad ósea entre los estadios T2 y T3, T3 y T4, y T2 y T4 fue de 1,02 ± 0,60 y 0,91 ± 0,65, de 1,12 ± 0,76 y 0,96 ± 0,59 y de 2,13 ± 1,29 y 1,74 ± 1,04. Entre T2 y la menarquia fue de 3,17 ± 1,25 y 2,66 ± 1,38. 4. Las velocidades de crecimiento expresadas en centímetros en tiempo real transcurrido y en cm/año entre T2 y T3 fueron de 5,05 ± 2,09, 5,75 ± 2,80 y 8,40 ± 1,80, 6,24 ± 1,74 (p=0,01), respectivamente. Entre T3 y T4, de 4,74 ± 1,54, 4,97 ± 2,82 y 7,31 ± 2,14, 7,14 ± 1,68, respectivamente. Entre T2 y T4, de 9,40 ± 3,70, 10,90 ± 4,13, y 7,40 ± 2,18, 6 ± 75,1,34. Entre T2 y la menarquia de 13,62 ± 4,41, 15,96 ± 5,42 y 7,20 ± 57, 6,90 ± 1,27. CONCLUSIONES: Las mujeres hipotiroideas desarrollan una pubertad normal, salvo que la inician más tardíamente, es algo más rápida, y tienen un crecimiento posmenarquia más prolongado que la población testigo. La maduración ósea y la velocidad de crecimiento son similares en ambas poblaciones y las dos consiguen una talla final normal en relación con su talla genética (AU)

ABSTRACT

INTRODUCTION: Cerebral hemorrhages in full-term newborn babies are an important factor in neonatal morbidity and mortality and very frequent in premature babies. In full-term newborn the frequency is reduced to 1-2% and the aetiopathogenesis is basically related to birth trauma. OBJECTIVE: To identify the clinical forms of cerebral hemorrhages in full-term newborn before taking prophyllactic and/or therapeutic measures if possible. DEVELOPMENT: Based on the integrated physio-pathological model of Wigglesworth and Pape, two anatomo-pathological patterns were established according to gestational age. Topographic classification was done in full-term newborn according to site (subarachoid, subdural, intraventricular, cerebellar and intraparenchymatous). We studied the pathogenesis, clinical features and diagnosis of each of these sites and emphasize the importance of neuroimaging. CONCLUSIONS: The diagnostic approach proposed permits an aetiopathogenic and therapeutic view which currently permits improved prognosis and even cure in many cases.
