[An evaluation study of a scale of diabetological education in primary care].

Objective: To devise and evaluate a scale of measurement which would permit evaluation at primary care level, of the knowledge that diabetic patients have of diabetes. Secondly, to ascertain the level of knowledge of the sample of diabetic patients attending the Xixona Health Centre.

Design: Non-longitudinal, observational, descriptive study.

The prevalence of diabetic retinopathy in northwest Spain. An epidemiological study of diabetic retinopathy in Galicia. I.

The prevalence of retinopathy was studied in a group of 1179 diabetic patients attending 11 diabetologic centres in Gallica (Northwest of Spain). The age of the patients was 61.7 +/- 13.

[Sphenoidal hyperostosis. Problems of differential diagnosis: report of a case].

A case of sphenoid hyperostosis is described in a patient whose clinical history and radiological work up suggested fibrous dysplasia. A year later, the biopsy and MRI showed evidence of a meningioma en plaque. Problems in the differential diagnosis are discussed among entities which present sphenoid hyperostosis: osteoma, Paget's disease, sphenoid meningioma and fibrous dysplasia.

[Primary angiosarcoma of the heart. A report of a new case and a review of the literature].

The case is presented of a primitive heart angiosarcoma (PHA) in a 53-year-old woman who developed repeated episodes of hemopericardium with cardiac tamponade. A literature review is performed. PHA is the most frequent primitive cardiac tumor.

Drug-induced agranulocytosis: prognostic factors in a series of 168 episodes.

The prognostic value of 36 clinical and analytical parameters at diagnosis in patients with drug-induced agranulocytosis was analysed in an adult population. This multicentre, retrospective study examined possible prognostic factors by multiple logistic regression analysis in a series of 168 clinical episodes. The overall mortality was 16%.

Lack of useful clinical predictors of response to splenectomy in patients with chronic idiopathic thrombocytopenic purpura.

We set out to identify clinical or analytical variables that might predict the response to splenectomy in patients with chronic idiopathic thrombocytopenic purpura (ITP). We retrospectively examined 138 mostly adult patients with chronic ITP, treated with splenectomy. Information was compiled from five Public Health Hospitals from a questionnaire and chart review.

[Experience with the use of an implantable automatic cardioverter defibrillator].

An automatic implantable cardioverter-defibrillator with pacemaker was implanted in Cuba, in ten patients with malignant ventricular arrhythmias, sudden cardiac collapse, and ventricular tachycardia with syncope, after a previous electrophysiological study for analysis of the arrhythmia and pharmacological evaluation. The patients were 9 males, ranging in age from 23 a 70 years, with a mean of 48 years, and an ejection fraction of 32% (18-62%). The etiologies were: an old myocardial infarction (7 cases) and dilated cardiomyopathy (3 cases).

Antibody response to the 43 kDa glycoprotein of Paracoccidioides brasiliensis as a marker for the evaluation of patients under treatment.

Sera of patients with paracoccidioidomycosis contained IgG-, IgA-, and IgM-specific antibodies to a 43 kDa antigen contained in the filtrate of a culture of Paracoccidioides brasiliensis. IgG- and IgA-specific antibodies were present in all observed patients. The IgM response was more frequent in acute cases, and the mean titers of IgG- and IgM-specific antibodies were higher in the acute forms.

[Chronic lead poisoning caused by wine consumption: an epidemiologic study].

An epidemiological study was carried out after the observation of a case of chronic lead poisoning so as to investigate its possible sources. An environmental evaluation was performed, including an analysis of the waters and wines consumed by the involved family; blood samples were obtained to assess lead levels in the consumers of the possibly implicated wines, with a comparative analysis of controls living in the same area. The study revealed that the source of the poisoning were the claret and white wines, which made soluble the lead when passing through the outlet tubes of the storage casks.

Bisoprolol vs. chlorthalidone: a randomized, double-blind, comparative study in arterial hypertension.

The antihypertensive effect and tolerance of bisoprolol and chlorthalidone were evaluated in a randomized, double-blind, controlled trial during 4 weeks of treatment. A total of46 patients, aged 18-65 years, were initially included; 41 patients presenting with a diastolic blood pressure between 95 and 120 mm Hg at the end of a previous placebo period completed the trial. They were randomly allocated to two groups: 22 patients were treated with bisoprolol 10 mg o.

[Treatment of skin ulcer using oil of mosqueta rose].

Oil rose of mosqueta (Rosa aff. Rubiginosa L.) is a concentrated solution in linoleic (41%) and linolenic acid (39%), that offers benefit therapeutic effects in the wound healing.

Detection of the 43,000-molecular-weight glycoprotein in sera of patients with paracoccidioidomycosis.

The 43,000-molecular-weight (43K) soluble glycoprotein was detected in sera of patients with paracoccidioidomycosis by the immunoblot technique by using as the probe rabbit monospecific antisera to this fraction. The 43K antigen was present before treatment in sera of patients with the acute (juvenile) form; it started to disappear from circulation after 10 months of chemotherapy, and it was undetectable after 2 years of treatment. In the chronic cases, the 43K antigen was detected in patients without treatment, and it was absent in the healed cases.

[Comparative study of gallbladder volume and contraction in healthy subjects of various ages and sex by ultrasonography].

Gallbladder motor function moderates the enterohepatic circulation which is determinant in bile composition. Cholelithiasis due to cholesterol stones increases with age and is more frequent in women. We studied the effects of age and sex on the gallbladder volume and contraction in 160 healthy subjects.

Conditioned turning and functional recovery after unilateral substantia nigra lesion in rats.

In order to investigate whether conditioned circling interferes with recovery from turning induced by unilateral substantia nigra (SN) lesion, rats were trained to turn either ipsi- or contralateral to the lesioned side before and after the lesion was made. Two yoked groups served as controls. The number of turns contralateral to the trained side was significantly lower in relation to the pre-lesion value for the ipsilateral trained group and remained so until the end of the experiment.

[Alpha-adrenergic receptors in the hepatic sinusoid of the rat and its relation to portal pressure].

The presence of alpha-adrenergic receptors in the hepatic sinusoid of the rat, and its relation to portal pressure (PP), by local and systemic infusion of bolus doses of norepinephrine (NE) (1 microgram/100 g) and phentolamine (FA) (25 micrograms/100 g) have been studied. Fifty-five male Wistar rats with intact nerves have been used in 5 experiments. When NE is injected into the portal vein (PV), it provokes an immediate rise in PP, modified subsequently by the systemic effect is induced earlier and more intensely than if injected into PV.
