Study of bone mineral density in lumbar spine and femoral neck in a Spanish population. Multicentre Research Project on Osteoporosis.

The aim of this study was to generate standard curves for bone mineral density (BMD) in a Spanish population using dual-energy X-ray absorptiometry (DXA), at both lumbar spine and femoral neck sites. The total sample size was 2442 subjects of both sexes aged 20-80 years, stratified according to survival rates, demographic distribution by local regions and sex ratio in the Spanish population. Subjects with suspected conditions affecting bone metabolism or receiving any treatment affecting bone mineralization were excluded. The study was carried out in 14 hospitals and bone density measurements were performed, using a QDR/ 1000 Hologic device. In the female population, the highest value for lumbar spine BMD was found within the 30-39 years age group, being significantly lower after the age of 49 years. In the male population, the highest values for lumbar spine BMD are found one decade earlier than in the female population and become significantly lower after the age of 69 years. The highest values for femoral neck BMD in men and women was found in the 20-29 year age group. Values for femoral neck BMD in the female population become statistically lower after the age of 49 years, while in the male population this effect was seen after the age of 69 years. Values for femoral neck BMD were higher in men than women at all ages.

[A double-blind study comparing the clinical efficacy of the preparation F-117 (hidrosmin) versus diosmin in the treatment of patients with peripheral venous disorders]. / Estudio doble ciego comparando la eficacia clínica del preparado F-117 (hidrosmina) versus diosmina en el tratamiento de pacientes con trastornos venosos periféricos.

A controlled double-blind clinical trial was performed comparing therapeutic efficacy of hidrosmin versus diosmin in patients suffering from chronic venous insufficiency with varicose symptomatology in the inferior limbs. Ten patients were treated with hidrosmin and other 10 with diosmin randomly. The controls carried out during the trial were as follows; basal control before the beginning of the trial and therapeutic controls on days 15, 30, 60 and 90 of the study. With that aim clinical examinations and different explorations were performed: physical exam, phlebography, electrocardiogram, ophthalmological examination and biochemical analyses (hemogram, globular sedimentation rate, platelet counts, etc.). The clinical therapeutic efficacy of hidrosmin in the treatment of chronic venous insufficiency of inferior limbs was superior to the diosmin in most of the studied parameters even though a lower posology was employed. From a clinical point of view the clinical improvement in the subjective symptomatology (heaviness, local tenderness, cramps, paresthesias, etc.) was very superior to the one obtained with the objective signs (phlebography, skin trophism, evolution of the edema, etc.). No significative adverse reactions appeared.

[Pediatric pharmacology: is treatment of children preceded by an adequate investigation?]. / Farmacología pediátrica: va la terapéutica infantil precedida de una adecuada investigación?

The articles published in 1985 in 9 journals (3 of Internal Medicine, 3 of Pediatrics and 3 of Clinical Pharmacology) are revised with the purpose of studying: a) Number of clinical trials published. b) Number of clinical trials published accomplished in children. Among the 533 trials published, 102 were done in children. The type of trial done is studied based on the methodology used, if healthy volunteers are included, if pharmacokinetics studies were done, the ages of the subjects, the number of subjects included, the sex and the way of obtaining the informed consent.

Meclofenamate sodium in the treatment of post-traumatic edema. Report of a controlled double-blind study.

130 patients with edema as the sequel of a traumatic incident were selected for this study, 43 patients were treated with 300 mg N-(2,6-dichloro-m-tolyl)anthranilic acid, sodium salt (meclofenamate sodium, Meclomen) per day for one week, 44 patients received 600 mg oxyphenbutazone per day and 43 patients received placebo. Medication could be terminated if edema and pain disappeared or if deterioration or intolerance occurred. Extent of edema and degree of pain were assessed at entry into the study and on days 3, 5 and 8. Efficacy was assessed by the number of days elapsed before definite reduction and/or complete disappearance of edema and by the decrease and disappearance of pain. Meclofenamate sodium proved to be significantly superior to placebo in the treatment of patients with post-traumatic edema and post-traumatic pain. Reduction and disappearance of edema and cessation of pain occurred significantly more promptly in patients receiving meclofenamate sodium than in those receiving placebo. Although no statistically significant differences were observed between meclofenamate sodium and oxyphenbutazone, the results suggested that meclofenamate sodium might be clinically superior. Meclofenamate sodium was well tolerated.
