[Postmenopausal osteoporosis. Digital Rx radiogrammetry in the diagnosis and follow-up of treatment with alfacalcidol].

Postmenopausal osteoporosis is characterised by an increased resorption of trabecular bone, a consequence of estrogen deficit. Changes in vitamin D metabolism are also an important contributors to the development of osteoporosis in postmenopausal women. Vitamin D and its active metabolites (Alfacalcidol, Calcitriol) perform important functions in regulation of the calcium balance and the bone metabolism.

[Normal bone mineral content levels determined by quantitative computer tomography (QCT) in the population of Moldavia].

Unlabelled: To determine by QCT-BMD the normal osteodensitometric levels in the population of both sexes (18-80 years) from Moldavia districts.

Material And Method: The study used the BMD (bone mineral density) option of CT PACE GE-CGR (QCT) device which compares the CT levels in the area of interest restricted to the trabecular area of L1-L4 vertebrae with the values of a phantom with different hydroxyapatite concentrations. In order to develop a regional standard, an average of 10 both sexes subjects free of osteoporosis-generating diseases were investigated per each 5-year age group, age range 18 to 80 years, selected at random from the 8 districts of Moldavia.

[The clinical, imaging and electrophysiological correlations in Paget's disease].

The work presents two cases of Paget disease with a complex neurological description. The first case, a woman of 59 years, presents a spastic paraparesis with multiple syndrome of cranial nerves. The second case, a woman of 60 years, presents a spastic tetraparesis with myoclonus.

[The imaging and electrophysiological correlations in lateral homonymous hemianopsia of vascular origin].

This paper presents 7 cases of patients suffering of lateral homonymous hemianopia. This diagnosis was established taking into account both the clinical exam as well as the visual field, into the context of a vascular suffering of hemiparesis type. I worked with a Bioscript BST 2100 apparatus foreseen with flash and with its help there could have been recorded the visual evoked potentials (VEPs) with electrodes occipitally placed.

[The antiemetic action of tropisetron (Navoban) in the cytostatic treatment of neoplastic diseases].

The most frequent side effects of chemotherapy are nausea and vomiting. This issue is a clinical analysis of the protective effect of a 5HT3 antagonist (Navoban-R; Sandoz Pharma Ltd., Basel, Switzerland) against chemotherapy--induced emesis (especially with the most emetic cytostatics--cisplatin and dacarbazine).
