Seventeen cases of adrenal cytomegaly were reviewed. False intranuclear inclusions were noted in 11 cases. In three of them, electron microscopy showed that the nuclear inclusions were composed of the invaginated portion of the cytoplasm surrounded by double membrane and contained numerous organelles.
Clinico-pathological conference concerning a syndrome, characterized by considerable diagnostic problems. Polyneuropathy, adrenocortical insufficiency and diarrhea without typical changes in laboratory or functional data should always lead to the suspicion of primary amyloidosis. This diagnosis could be confirmed in the discussed case report. Its clinical relevance in regard to the type of spreading--perireticular or pericollagenous--is discussed, methods for identification are mentioned.
The personality characteristics of gynecological patients with hormonal dysfunction versus hormone dependent pathology were compared, using a factorial analysis of answers to 377 questions of the Russian modified variant of MMPI and a cluster analysis of intergroup subdivisions. A group of patients with uterine myoma (UM) differed considerably from all the others in relation to six "varimax" factors. A new factor scale was elaborated which makes it possible to differentiate a group of patients with UM from both healthy women and other gynecological patients. The results obtained are discussed in the light of the hypothesis about the psychosomatic nature of UM. The factor scale presented may be utilized for detecting a group of high risk for UM development.

The finding of hypoglycemia after the surgical removal of a pheochromocytoma in two patients in a previous study led to monitoring of the serum glucose and plasma C-peptide levels in two other patients with a pheochromocytoma and one with unilateral adrenocortical hyperplasia. In the two patients with a pheochromocytoma endogenous insulin secretion, as measured by a C-peptide assay, was suppressed before removal of the tumours and resumed immediately after removal. The serum glucose levels decreased in these patients, but sufficient intravenous administration of glucose prevented postoperative hypoglycemia. In the patient with adrenocortical hyperplasia the plasma C-peptide level was not decreased before tumour removal, nor did it increase abruptly following removal. It therefore seems likely that the rapid fall in the serum glucose level following removal of a pheochromocytoma is caused by prompt resumption of beta-cell activity, with rebound hyperinsulinism.

Two patients with Cushing's syndrome due to primary adrenocortical nodular dysplasia (PAND) are described. Both patients, an infant and a 14-year-old boy at the time of diagnosis, were treated by total bilateral adrenalectomy. On gross inspection, the adrenal glands of the infant did not appear to be abnormal but those of the older patient showed numerous dark nodules. Microscopically, the adrenal glands of each patient manifested multiple micronodules with internodular atrophy. The extreme internodular atrophy suggest that primary adrenocortical nodular dysplasia is a non-ACTH-dependent condition. Since the disorder appears to involve primarily the cortex of both adrenals, adrenalectomy followed by steroid replacement is the recommended treatment.

For the first time the surgical technique of right and left adrenalectomy by a posterior percutaneous retroperitoneoscopic access is described. The adrenal gland is mobilized after creation of a pneumoretroperitoneum and insertion of 3-4 trocars beneath the 12th rip. Indications for this new method are small, benign adrenal tumours or adrenocortical hyperplasias. By this method, the potential advantages of a posterior approach and minimally-invasive surgery are combined. This surgical technique might become a major advancement in adrenal surgery.
Desoxycorticosterone pivalate was administered IM to juvenile Beagles at 0, 2.2, 6.6, or 11 mg/kg of body weight daily over a consecutive 3-day period every 28 days (equivalent to a cumulative monthly dosage of 0, 6.6, 19.8, or 33 mg/kg) for 6 months. Polyuria, polydipsia, and decreases in serum potassium and BUN concentrations were detected while the dogs were being treated. Transient increases in serum sodium concentrations also were detected. The treated males had significant decreases in body weight gain, resulting in an 18% decrease in body weight in the 11-mg/kg dosage group, compared with the controls. The weights of the adrenal glands, epididymides, and testes also were lower in the treated males. Organ weights for the 2.2, 6.6, and 11-mg/kg dosage groups were: 86, 79, and 69%, respectively, of the controls (adrenal glands); 80, 70, and 68%, respectively, of the controls (epididymides); and, 79, 75, and 67%, respectively, of the controls (testes). When normalized to body weight, these decreases in organ weight were still dosage-dependent, but the differences were less remarkable. In contrast, the relative weight (to body weight) of the kidneys (males and females) and of the thyroid and parathyroid glands (males) were higher dosage-dependently. All of the treatment-related effects, other than organ and body weight changes, appeared to be reversible following the cessation of treatment. On the basis of these results, it was concluded that treatment with desoxycorticosterone pivalate could be tolerated, even when given at dosage 15-fold the therapeutic dosage of 2.2 mg/kg every 25 days.

Genitourinary tuberculosis (TB) rarely involves the adrenal gland. A 67-year-old man presented with progressively hyperpigmented skin and an enlarged mass over both testes. Early morning plasma cortisol concentration was low and adrenocorticotropic hormone (ACTH) concentration was high. A rapid ACTH stimulation test revealed the absence of plasma cortisol response and confirmed a diagnosis of primary adrenocortical insufficiency. An abdomen computed tomography (CT) scan disclosed enlargement of the right adrenal gland and punctuate calcification over the left one. This is compatible with tuberculous adrenalitis. Currettage biopsy of the prostate demonstrated chronic granulomatous inflammation with Langerhan's giant cells, but without TB bacilli. Anti-TB treatment, in addition to glucocorticoid and mineralocorticoid replacement, was administered. The testicular mass decreased progressively though the results of a subsequent ACTH stimulation test, six months later, disclosed no significant change. A follow-up CT scan, one and a half years later, showed a decrease in the size of the right adrenal mass.
