Lymphocytic thyroiditis. I. correlation between morphological, immunological and clinical findings.

Biopsies from the thyroid glands in 32 selected patients with goitre and lymphocytic thyroiditis have been investigated with quantitation of the morphological changes. This permitted a comparison with immunological and clinical findings. The three main elements in the destruction of glandular tissue--lymphocytes, plasma cells and fibrosis varied relatively independently of each other as an expression of the great variation in the appearance of the tissue lesion. Thyroglobulin antibodies showed a correlation to the number of plasma cells, whereas the microsomal thyroid antibodies showed a correlation to the number of lymphocytes. The morphologic changes were independent of the duration of the disease. The degree of fibrosis increased parallel with age and there was a tendency towards glandular fibrosis in myxoedematous patients.

Lymphocytic thyroiditis. II. The course of the disease in relation to morphologic, immunologic and clinical findings at the time of biopsy.

Thirty-two patients with goitre and lymphocytic thyroiditis were followed for 1 1/2--19 years (average 7) after open surgical biopsy. Treatment with thyroid hormone was started when myxoedema was diagnosed. Five patients (group A) regained normal glandular size, remained euthyroid and had elevated antibody titres. Six patients (group B) continued to have goitre and elevated antibody titres and remained euthyroid. Thirteen patients (group C) developed myxoedema, while 8 (group D) demonstrated myxoedema at the time of biopsy. The patients in groups C and D had a higher average age and their biopsies showed more marked fibrosis compared with groups A and B. The goitre disappeared during treatment in 62% of the patients and the microsomal antibody titre also decreased in them, whereas the thyroglobulin antibody titre decreased in all treated patients. The results indicate that the degree of fibrosis in the thyroid gland is of overall importance for the prognosis with regard to glandular function. It seems evident that the treatment with thyroid hormone influences the autoimmune process so that the activity decreases.

Accidental fatal drug poisoning with particular erference to dextropropoxyphene.

A rapid increase in fatal accidental dextropropoxyphene poisonings which is proportional to the increased use of the drug is reported. In 30 accidental poisonings dextropropoxyphene was responsible for 50% of the cases, and is the most common accidental medical poisoning at the present time. This is probably due to the unappreciated narrow margin between therapeutic and fatal dose and the simultaneous intake of alcohol which increases the resorbtion speed from the gastro-intestinal tract. In Denmark a slow-release preparation is frequently used. which is especially dangerous because of repeated dosage by the patient attempting to induce the therapeutic effect more quickly.

The histology of myocardium in malignant hyperthermia: a preliminary report of 11 cases.

The preliminary results of a retrospective examination of the myocardium from 11 patients who responded to general anaesthesia with malignant hyperthermia are presented. Light-microscopical examination of the sections revealed no specific changes due to malignant hyperthermia. Contraction bands were demonstrated in 4 cases and it is concluded that the present investigation does not support the suggestion that a specific myofibrillar damage is responsbile for the arrhythmias seen in malignant hyperthermia.
