Prevalencia de causas secundarias de baja masa ósea en una población de mujeres premenopáusicas / Prevalence of secondary causes in a population of premenopausal women with low bone mass

La osteoporosis es un trastorno común en las mujeres posmenopáusicas; sin embargo, también puede afectar a hombres y mujeres jóvenes premenopáusicas. El objetivo del presente trabajo fue evaluar la prevalencia de causas secundarias de baja masa ósea en un grupo de mujeres premenopáusicas que consultaron en una Institución especializada en Osteología. Material y métodos: se realizó un estudio retrospectivo, de corte transversal, descriptivo y observacional. Se analizaron las historias clínicas de 88 pacientes que consultaron por baja masa ósea durante un período de 19 meses, con la finalidad de encontrar posibles causas secundarias. A su vez, se definió como pacientes con diagnóstico de baja masa ósea idiopática aquellas en las cuales no se encontró ninguna causa secundaria de pérdida ósea. Resultados: de las 88 mujeres evaluadas, el 48,9% presentaba al menos una causa secundaria para baja masa ósea (amenorrea secundaria, hipercalciuria, tratamiento con glucorticoides, hipovitaminosis D y enfermedad celíaca) y el 51,1% fueron consideradas idiopáticas. Conclusiones: es esencial evaluar exhaustivamente a las mujeres premenopáusicas con baja masa ósea a fin de descartar posibles causas secundarias y tomar las medidas preventivas necesarias para mejorar esa condición.

Objective: osteoporosis is a common disorder in postmenopausal women, however it can also affect men and premenopausal young women. The purpose of this study was to evaluate the prevalence of secondary causes of low bone mass in premenopausal women that consulted physicians in an institution specialized in osteology for a period of 19 months. Material and methods: this is a retrospective, transversal, descriptive and observational study. The clinical history of 88 patients who consulted a physician due to low bone mass for a period of 19 months in an institution specialized in osteology. Were analyzed the patient's clinical history in order to find secondary causes. We define as suffering Low Bone Mass those patients who did not have secondary causes. Results: of the 88 women tested, 48,9% had one or more secondary causes or risks factors for low bone mass (secondary amenorrea, hypercalciuria, treatment with glucocorticoids, hypovitamiosis D and celiac disease) and 51,1% patients were considered idiopathic. Conclusions: we conclude that it is essential to exhaustively search for secondary causes of low bone mass in premenopausal women, due to the high prevalence of secondary osteoporosis in this population.

Spontaneous remission in idiopathic hyperprolactinemia.

In this report we describe a 37 year old lady who was demonstrated to have hyperprolactinemia causing amenorrhea-galactorrhea syndrome. Computerized tomography scan done twice did not reveal any sellar or suprasellar abnormality and there was no clinical or biochemical evidence of primary hypothyroidism. She had regression of galactorrhea, resumed regular menstrual cycles, and conceived twice on bromocriptine therapy. Following her second delivery she noticed spontaneous remission of galactorrhea and, prolactin levels estimated multiple times were normal.

Deletion/inversion in the X-chromosome and increased telomeric associations in a female with primary amenorrhea

Um novo caso de supressäo e inversäo intersticial parcial do braço longo do cromossomo X em combinaçäo com uma alta incidência de associaçöes teloméricas foi mostrado em uma jovem do sexo feminino de 18 anos com características sexuais secundárias subdesenvolvidas, incluindo seios pequenos e amenorréia primária. Seu cariótipo foi considerado 46,X,del(Xq13 q22)inv(X)(q23-q27). As células mucosas bucais apresentaram ausência de um típico corpúsculo de Barr e os estudos de incorporaçäo de 5'-bromo-2-deoxiuridina revelaram que nem o cromossomo X normal nem o anormal tinham replicaçäo tardia. Este caso foi apresentado por sua extrema raridade.

True 47,XXX in a patient with premature ovarian failure: the first reported case in Thailand.

A case of triple-X female with premature ovarian failure was reported. The patient was a 23-year-old, single, Thai woman who presented with primary amenorrhea, incomplete development of the secondary sex characteristics, elevated levels of serum gonadotropins, and decreased estrogen concentration. Immunological abnormalities were not identified by antinuclear antibody, rheumatoid factor, antimicrosomal antibody and antithyroglobulin antibody studies. Cyclic estrogen-progestin was given and withdrawal bleeding occurred. The present case represents the utilization of chromosomal analysis in a patient with delayed sexual development, or primary amenorrhea and elevated serum gonadotropin levels.
