We have realized the test of cold in a group of patients with ischemic cerebrovascular attack (AVCi) and in a control group. The comparison of results shows a different vascular reactivity into the groups. At present, it is unknown if there is a relation of this finding with the AVCi occurrence.

The incidence of stressful life events in the six months previous to psychiatric hospitalization is studied in a group of patients allotted to different diagnostic categories but which held in common that they were at their first episode of inpatient treatment. The presence of early life events during childhood and of chronic stress during the last year is also investigated. The different kind of responses to LE are described, classified in several categories. The incidence of LE in the patients is compared with that of a group of acute traumatologic hospital inpatients. In every case it has been used the Paykel LE rating scale, the Brown and Harris interview schedule and the GAF. Results are analyzed and their implications in preventive and treatment programs in Mental Health are discussed.

The levels of Neurotensin, VIP, Somatostatin, beta-endorphin and Bombesin have been investigated in plasma of 16 depressed and 20 anxious patients. VIP and Neurotensin were found significantly decreased in patients vs a group of 20 controls. Neurotensin levels returned to normal values after recovery. There were no significant differences from the normal in the concentrations of Somatostatin, beta-endorphin and Bombesin in the disease groups.

The development of psychiatry, as it happens with other medical specialties, has been linked to that of the journals dedicated to it. They are a good exponent of its state of growing or consolidation. The first psychiatric journal in Spain appeared in 1865 and 27 years later the next one was founded. None of the three journals which existed in the 19th century continued at the beginning of the 20th century. During the first three decades of this century, nine specialized journals were founded, among which the "Revista Frenopática Española" in the first place, and the "Archivos de Neurobiología" afterwards, were the most outstanding in our country and the "Revista Frenopática Española" was that of the greatest international projection. Although the importance of a constellation of prestigious journals which were not dedicated to psychiatry was decisive for the development of this discipline in our country, the professionals organized themselves in the monographic journals about this subject, linked to mental hospitals.

In this paper we analyzed some aspects about the treatment of agoraphobic patients. We studied the type of professionals, institutions and therapies prescribed to the patients and some practical implications are discussed.

The factors found in the approach taken towards the disturbances caused by anxiety on the part of the doctors working outside the hospital environment are analyzed. After studying a sample of 45 patients seen consecutively in the outpatient clinica of a general hospital and evaluating their clinical, evolutive, social-demographical characteristics and the type of medical care received previously, we found an important tendency towards diagnostic error which does not seem to be related to the degree of specialization by the medical practitioner who treated the patient. A profile of a patient having a higher risk of receiving and incorrect diagnosis is elaborated.

Quantified electroencephalography (EEGq) by means the Fast Fourier Transformed system (FFT) was carried out on two groups of patients with idiopathic Parkinson's Disease (PD). The first one was with symptoms of cortical deterioration, and the second group consisting of subjects without signs of cortical impairment. The study of the specific EEGq indices has led to the establishment of parameters which establish differences between these two groups. Specifically, a difference has been found with regard to the total potentials of delta and alpha frequency bands; alpha/theta index; posterior activities; changes in the lobular antero-posterior of delta and alpha rhythms; and in the distribution of the spatialization index of alpha rhythm. We discuss the implications of this electrophysiological differentiation between the two groups, regarding the possible frontal lobe affection in the subcortical dementiation of the Parkinson's disease.
