The authors propose a comprehensive treatment of patients with hypothalamic syndromes (vegetative-visceral vascular forms) by a differentiated use of electrophoresis of euphellin. This method was efficacious in expressed headaches with increased blood pressure and cerebral vessels tone, crises of a sypmathico-adrenal character. Electrophoresis of adrenalin was mainly indicated in symptoms of sympatho-adrenal insufficiency and crises of a vago-insular structure.

Norgestrienone implants delivering approximately 225 microgram/ day were tested clinically for contraceptive effectiveness and acceptability in 145 women. Five pregnancies occurred in 2259 woman-months of use, one in the 11th month, one in the 15th and three in the 16th month of use. Continuation rate at 12 months was 86.7. The number of bleeding runs and bleeding days was increased in approximately 12% of the subjects. Ten percent of the patients had no bleeding in the first 90 days of treatment. Changes in bleeding pattern led to closures in four cases. Headache and signs of mild androgenicity were among the leading side effects. Blood and urine analysis throughout the study showed normal values of 17 different parameters, but a tendency to lower cholesterolemia not associated with changes in thyroid hormone levels, was observed in several patients. Cortisol was found slightly under the lower normal range in one subject without clinical manifestations of hypoadrenalism. It is concluded that norgestrienone implants should be replaced every twelve months for maximal contraceptive effect and because of their efficacy and good acceptability, evaluation of their long term use is warranted.

From 1962 to 1987, 126 patients underwent trans-sphenoidal surgery for primary treatment of pituitary adenomas unassociated with clinical or biochemical evidence of hormonal overproduction. There were 73 male and 53 female patients (mean age, 50 +/- 12 years). Before surgery, 56% of the patients (70 of 124) had headaches, 74% (94 of 126) had deterioration of vision, and 12% (15 of 126) had ophthalmoplegia. Endocrine evaluation revealed the presence of hypogonadism in 75% (87 of 115), adrenal insufficiency in 36% (46 of 126), and hypothyroidism in 18% (21 of 122). Plasma prolactin was increased in 65% (56 of 86) with a mean level of 39 +/- 14 micrograms/l (normal, 3 to 20 micrograms/l). Radiologic enlargement of the sella turcica was documented in all cases: 67% (84 of 126) had enclosed and 33% (42 of 126) had invasive adenomas. After surgery, vision was normalized or improved in 75% (71 of 94) of the patients. Thyroid, adrenal, and gonadal functions were improved in 14% (three of 22), 41% (19 of 46), 11% (ten of 87), were unchanged in 82% (100 of 122), 77% (97 of 126), 89% (102 of 115), and worsened in 15% (19 of 22), 8% (ten of 126), 3% (102 of 115), respectively. Permanent diabetes insipidus occurred in 5% (seven of 126). Two patients died during the immediate postoperative period. The recurrence rate in patients with a mean follow-up of 6.4 +/- 4.2 years was 21% (15 of 71). These data indicate that trans-sphenoidal microsurgery is an effective and safe initial treatment for patients with nonsecreting pituitary adenoma and may reverse hypopituitarism.

Pituitary apoplexy is characterized by a wide spectrum of clinical features. A quite rare case of painless thyroiditis, hypopituitarism and central diabetes insipidus (DI) followed by pituitary apoplexy was presented. A 61-year-old woman was admitted to our hospital in May, 1986 because of marked general malaise, polydipsia and weight loss which became progressively worse. Four months earlier she had experienced episodes of abrupt onset of severe headache associated with nausea and blurring vision. Physical examinations revealed a fine tremor, dry skin and nervousness. The thyroid gland was not palpable. Visual fields were intact. Her blood pressure was 105/64 mmHg with variable tachycardia. The routine laboratory studies were normal or negative except for hypoalbuminemia, hypocholesterolemia and hypernatremia. Erythrocyte sedimentation rate was 12 mm/hr. An impairment in corticotropin secretion was suspected from the low plasma cortisol and the low urinary excretion of 17-OHCS and the sufficient response to ACTH. Basal levels of GH and gonadotropin were also low, and responses to the stimulation tests (Insulin-stress, L-DOPA, and LH-RH) were all blunted. Brain computed tomographic scan and magnetic resonance imaging demonstrated a suprasellar mass that, after infusion, developed peripheral ring-like enhancement and large hyperintense pituitary mass, respectively. A diagnosis of pituitary apoplexy with anterior pituitary failure was made. However, the initial levels of thyroid hormones showed elevated as follows: Free T3 7.6 pg/ml, Free T4 3.3 ng/dl and T3-resin uptake 41.1%. TSH responses to TRH were all suppressed. TSH receptor antibody (TBII) was negative. Both antithyroglobulin and antimicrosomal antibodies were repeatedly positive. A thyroid scan with 99mTc revealed no uptake in the thyroid area. These findings led us to the diagnosis of "painless autoimmune thyroiditis". She had become hypothyroid without any medication. At that time radioactive 99mTc and 123I uptakes increased significantly. When hydrocortisone was substituted, daily urine output abruptly increased to about 10 liters with low osmolality, and the presence of DI was suspected. This diagnosis was confirmed by water deprivation and hypertonic saline infusion tests and subsequent pitressin test. She is currently quite well on L-thyroxine, hydrocortisone and desmopressin (1988). This association with pituitary apoplexy must be a rare occurrence, as a literature search has failed to find a similar case. The pathogenetic trigger of "painless thyroiditis" in this case may be responsible for some immunological change due to secondary adrenal insufficiency after pituitary apoplexy.

A series of 74 patients with craniopharyngiomas were treated during a 15-year period. Of the 74 patients, 40 were males and 34 were females, with a mean age of 27 years (range 3 to 65 years). Twenty-eight patients (38%) were less than 18 years of age. Remission was defined as clinical improvement with stable ophthalmological and neurological status, radiological evidence of a decrease in tumor size, and either a continued decrease or a stable tumor size on follow-up radiological evaluations. A fair result was considered remission with new neurological deficits related to surgical intervention. All other results were considered a failure. The mean follow-up period in this study was 4 years, with 100% of the patients monitored. In children, the most common presentation was that of growth failure (93%). In adults, sexual dysfunction was the most common presentation, with 88% of males presenting with impotence or marked decrease in sexual drive, and 82% of females presenting with primary or secondary amenorrhea, often associated with galactorrhea. Considering the pediatric and adult populations together, the most common presenting symptom was visual dysfunction, with 71% of patients presenting in this manner. Fifty percent of patients presented with severe headache. The most frequent preoperative finding was a visual field defect, with 72% of patients so affected; 42% of patients had preoperative hypothyroidism and 24% had hypoadrenalism. Diabetes insipidus was present preoperatively in 23%. Hydrocephalus was uncommon, being present in only 15%. A subfrontal craniotomy was used in 47% of patients, a transsphenoidal approach in 39%, a subtemporal approach in 11%, a transcallosal approach in 5%, and a suboccipital craniectomy in 2%. Multiple procedures were required in 15% of patients in order to provide significant relief of compressive symptomatology. The results of therapy indicate that total tumor removal was deemed to have been achieved in only seven patients, six of whom have had no recurrence. However, 91% of patients are in remission, one had a fair result, and two died as a direct result of surgical intervention. One patient died from uncontrolled disease, and three patients died from unrelated causes. The results of this study indicate that radical subtotal removal followed by radiotherapy is an acceptable treatment for craniopharyngioma.

A 37-year-old woman undergoing endocrine evaluation during her seventh pregnancy because of headaches, weakness, and hyponatremia was found to have central hypoadrenalism and hypothyroidism. Computed tomography showed a pituitary mass with suprasellar extension but her visual fields were intact. She was treated conservatively with hydrocortisone acetate and levothyroxine sodium until 38 weeks of gestation, when healthy twins were delivered by cesarean section. A few months later, her pituitary function improved, with a significant increase in the adrenocorticotropic hormone level, normal values of basal thyroid-stimulating hormone, growth hormone, and gonadotropins and of their functional reserves, and only a slight elevation in the prolactin level. A repeated computed tomographic scan showed disappearance of the pituitary mass.

We report the first case of pseudotumoral lymphocytic hypophysitis successfully treated by corticosteroids without surgery. A 27-year-old woman had been monitored for chronic headache 13 months after giving birth, associated with amenorrhea and galactorrhea. Cranial magnetic resonance imaging revealed a markedly enlarged pituitary gland with a suprasellar extension; the only biochemical abnormality was a mild hyperprolactinemia. Because of a putative diagnosis of prolactinoma, bromocriptine was prescribed at a dose of 5 mg daily, soon followed by the transitory appearance of menstruation. Two years later, panhypopituitarism was present and was revealed by acute adrenal insufficiency. Magnetic resonance imaging revealed that the pituitary mass was the same as previously described, but hormonal investigation showed evidence of complete hypopituitarism and no hyperprolactinemia. Nuclear antibodies were negative as well as other autoantibodies. Human leukocyte antigen serological Class II typing was DR3/DR4. Lymphocytic hypophysitis was then suspected; in the absence of visual complication and because this patient refused surgery, corticosteroids were attempted at a daily dose of 60 mg of prednisone for 3 months, progressively decreased for the next 6 months. Under this treatment, a gradual recovery of all pituitary hormones was observed and magnetic resonance imaging showed a reduction of two-thirds in pituitary mass. Five months after the end of corticoid treatment, our patient relapsed with panhypopituitarism and an increase of pituitary volume. She underwent steroid treatment, and a biopsy was performed and confirmed the diagnosis of autoimmune hypophysitis.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of lymphocytic hypophysitis is described in a patient presenting with panhypopituitarism 8 years after her last childbirth. The patient developed headache, vomiting, and diplopia (due to palsy of the right lateral rectus muscle) 7 months after delivery of her last baby. The diplopia disappeared after a few days with symptomatic treatment, and the headache and vomiting decreased in intensity with analgesic therapy. Eight years later the patient developed symptoms suggestive of hypoadrenalism, hypothyroidism, and amenorrhea. Investigations revealed panhypopituitarism with a pituitary mass lesion. Repeat evaluation 1 year later demonstrated no change in the size of the pituitary gland. The patient underwent transsphenoidal surgery with a provisional diagnosis of pituitary adenoma. Histological examination of the resected gland revealed evidence of lymphocytic hypophysitis. Symptoms suggestive of a pituitary mass lesion were noted during the peripartum period, but features of hypopituitarism developed much later. Such a long latent period has not been reported before. This report also highlights the fact that glandular enlargement may persist for many years after the onset of lymphocytic hypophysitis.

Pituitary apoplexy is a clinical syndrome of headache, visual deficits, ophthalmoplegia, and alteration in mental status resulting from the sudden hemorrhage or infarction of a pituitary adenoma. Infarction of a normal gland also may occur in certain circumstances. Its manifestations are variable, ranging from a clinically benign event to a catastrophic presentation with permanent neurologic deficits or even death. It frequently mimics other intracranial processes and, without a high index of suspicion, may be difficult to diagnose. Radiographic studies, particularly CT and MR imaging, are helpful for diagnosis in both the acute and subacute settings. In its most fulminant presentation, prompt neurosurgical decompression is necessary to preserve sight and life. Corticosteroid replacement is also essential in the acute phase because of the high incidence of adrenal insufficiency. Fortunately, however, with proper management most patients may have good outcomes.

Hyponatremia is rarely reported as a delayed complication of transsphenoidal resection of pituitary adenoma. Usually attributed to the syndrome of inappropriate secretion of antidiuretic hormone (SIADH), hyponatremia causes nonspecific symptoms, often after hospital discharge. To clarify the frequency, presentation, and outcome of this poorly understood complication, we reviewed our database of 2297 patients who underwent transsphenoidal pituitary surgery between February 1971 and June 1993. Of 53 patients (2.3%) treated for symptomatic hyponatremia, 11 were excluded (2 received arginine vasopressin within 24 hours, 1 had untreated hypothyroidism, 4 had untreated adrenal insufficiency, and 4 had incomplete records). The remaining 42 patients (1.8%), 11 men and 31 women aged 21 to 79 years, presented 4 to 13 days (mean, 8 d) postoperatively with nausea and vomiting (20 patients), headache (18 patients), malaise (12 patients), dizziness (4 patients), anorexia (2 patients), and seizures (1 patient). Hyponatremia was unrelated to sex, age, adenoma type, tumor size, or glucocorticoid tapering. Although the clinical picture in our patients is consistent with SIADH, this was not supported by the antidiuretic hormone levels, which were normal or low-normal in the two patients in whom they were measured, suggesting the possibility that low serum sodium may not reflect SIADH. In all patients, hyponatremia resolved within 6 days (mean, 2 d); treatment consisted of salt replacement and mild fluid restriction in 37 patients and fluid restriction only in 4 (treatment unknown in 1). Delayed hyponatremia after transsphenoidal resection of pituitary adenoma is not as rare as previously thought, nor is it necessarily associated with SIADH or with hypoadrenalism during glucocorticoid tapering.(ABSTRACT TRUNCATED AT 250 WORDS)
