Decreased growth hormone (GH) response to oral clonidine in endemic cretinism: effect of L-T3 therapy.

As GH secretion is dependent upon thyroid hormone availability, the GH responses to clonidine (150 micrograms/m2) and the TSH and PRL response to TRH were studied in eight endemic (EC) cretins (3 hypothyroid, 5 with a low thyroid reserve) before and after 4 days of 100 micrograms of L-T3. Five normal controls (N) were also treated in similar conditions. Both groups presented a marked increase in serum T3 after therapy (N = 515 +/- 89 ng/dl; EC = 647 +/- 149 ng/dl) followed by a decrease in basal and peak TSH response to TRH. However, in the EC patients an increase in serum T4 levels and in basal PRL and peak PRL response to TRH after L-T3 therapy was observed. One hypothyroid EC had a markedly elevated PRL peak response to TRH (330 ng/dl). There were no significant changes in basal or peak GH values to treatment with L-T3 in normal subjects. In the EC group the mean basal plasma GH (2.3 +/- 1.9 ng/ml) significantly rose to 8.8 +/- 3.2 ng/ml and the mean peak response to clonidine (12.7 +/- 7.7 ng/ml) increased to 36.9 +/- 3.1 ng/ml after L-T3. Plasma SM-C levels significantly increased in N from 1.79 +/- 0.50 U/ml to 2.42 +/- 0.40 U/ml after L-T3 (p less than 0.01) and this latter value was significantly higher (p less than 0.05) than mean Sm-C levels attained after L-T3 in the EC group (respectively: 1.14 +/- 0.59 and 1.78 +/- 0.68 U/ml). These data indicate that in EC the impaired GH response to a central nervous system mediated stimulus, the relatively low plasma Sm-C concentrations, and the presence of clinical or subclinical hypothyroidism may contribute to the severity of growth retardation present in this syndrome.

[Brief psychotherapy in clinical medicine patients].

The criteria that "illness is biographical crisis od the individual" and that the only medicine is "personal medicine" is stressed. Clinical medicine, which covers medicine in its entirety, demands conceptual and doctrinal reaffirmations so that gradually the patient can come to be dealt with as a human being fron a holistic point of view, which commences with his complaint and consultation, continues with the interview and semiology, to finish with the diagnosis and therapy which, although in some cases it may be surgical, is still medical and integral. All the steps mentioned are bio-socio-cultural thus, whether in the practice of general clinical medicine or in the most specialized and technologically sophisticated clinical medicine, the animist component is not lacking and demands a minimum degree of "psychosomatic" Knowledge. The use of a psychotherapeutic technique is proposed which, while based on the psychoanalysis theory, is distanced technically from it as a "psychotherapy on limited time and goals", which abbreviates the disease, and is projected not as the "focus" of therapeutic work, but as a re-evaluation of the "life style" of each individual, and tends to help to develop a "project for life" suited to the possible personal, familiar and social well-being of the "patient". Technically speaking, this modality of brief psychotherapy is based on the nonuse of transferential interpretations, on impeding the regression od the patient, on facilitating a cognitice-affective development of his conflicts and thus obtain an internal object mutation which allows the transformation of the "past" into true history, and the "present" into vital perspectives. This technique is within reach of every health professional.

Approach to a combined pharmacologic therapy of childhood hyperkinesis.

The pharmacologic management of childhood hyperkinesis with psychostimulants has repeatedly proved its efficacy. In the case of hyperkinesis with an organic background (with eviden electrocencephalographic signs), the association with different anticonvulsants is usually beneficial although at times it gives rise to exceptionally undesirable side-effects, or to a paradoxically depressant action of the psychic activity. A clinical trial was carried out in 30 children aged from 5 10 years, with 2-dimethylaminoethanol in association with a magnesium salt of dipropylacetic acid (DAP).
