Evaluación de un test de medición específico de la subunidad beta de la gonadotrofina coriónica humana / Evaluation of a test of specific measurement of human chorionic gonadotropin B-subunit in humans

Se investigó la eficacia de un test de mediación de la subunidad beta de la HCG en orina, en 61 pacientes bajo tratamiento de estrilidad en las cuales se sospechaba el embarazo por el tratamiento que estaban realizando. En 38 casos se obtuvo resultado positivo y en 23 negativo. Se analizan los resultados comparando edades, amenaza de aborto, embarazo ectópico y diferencias entre valores séricos y urinarios de la beta HCG. El test, demostró ser de fácil realización, rápido y confiable en cuanto a sus resultados, no reemplazando a los dosajes cuantitativos en los casos de amenaza de aborto, embarazo ectópico y progresión del embarazo normal

The role of physical exercise in prevention and management of osteoporosis.

The effect of exercises on vertebral trabecular bone mineral content (BMC) was investigated in 24 women with osteoporosis (OP) diagnosed by Quantitative Computed Tomography (QCT). Two groups were formed: an exercise and a control group with no exercise. Subjects in the exercise group exercised for one hour, twice weekly for a period of 6 months under the supervision of a physical therapist. A home exercise program which included the same exercises used in the hospital plus walking for half an hour every day was also assigned. Initial lumbar X-ray films, values obtained from laboratory investigations, physical activity scores and spinal BMC measurements were compared with those obtained after 6 months. The increase in the level of physical activity in the exercise group after exercise therapy was found statistically significant (p less than 0.001). After the exercise period, BMC values showed a 4.76% increase whereas in the control group, a decrease of 2.7% was found. The results demonstrated the beneficial effect of exercise in the prevention and management of OP.

[Determination of length, width and height of the human skull by critical use of roentgenologic craniometry methods]. / Zur Bestimmung von Länge, Breite und Höhe des menschlichen Schädels unter kritischer Anwendung der Methoden der röntgenologischen Kraniometrie.

X-ray craniometry has gained in importance for scientific and clinical examination. It enables accurate measurement of shape and structure of the human skull, its characterisation and an accurate description of the type and cause of changes of its shape and components. Roentgenological craniometry is closely related to craniometry of anatomists and anthropologists, but in a few essential points it does differ from it--rather fundamentally, in fact. On using the roentgenological method, the general laws of x-ray imaging must be strictly observed and measurements must be effected only if they are conducted from such points which are roentgenologically clearly defined. Measurements must be definite, repeatable at any time and suitable for comparative purposes. The influence exercised by these conditions becomes noticeable already on determining the three principal dimensions of the cranium. Whereas the x-ray determination of the length and breadth of the cranium is easy to perform and does not present any problem, determination of the "height" of the cranium causes considerable difficulties that are mainly based on the statement of suitable points of measurement. Detailed studies and deliberations have shown that the distance between the vault and the base of the skull can supply a suitable measure for assessing the height of the skull. On lateral x-ray film the distance between the "endobregma" and the "bony floor of the hypophyseal cavity" is a suitable criterion, whereas on the sagittal x-ray films of the skull the criterion is the distance between "bregma" and "hypophyseal basis". The "lateral hypophyseal height of the skull" and the "sagittal hypophyseal height" are largely equal, clearly defined and always repeatable.(ABSTRACT TRUNCATED AT 250 WORDS)
