Eighty four cases of meningococcal infections are reviewed. Fifty seven cases presented themselfs as meningococcal meningitis, twelve cases as sepsis with moderate hypotension and 15 cases were sepsis with septic shock. A brief course of the disease, shock, echymosis, absence of meningeal signs, leucopenia and intravascular coagulation were findings more frequent in the group of patients with hiperacute sepsis, whereas other signs as fever, headaches, vomiting and petechiae were present with equal frequency in the three groups. N. meningitis was isolated in 73% of the cases. Shock (18.85%) and intravascular coagulation (12%) were the complications more frequently found, followed by convulsions (4.81%), arthritis (4.81%), skin necrosis (4.81%), subdural efusion (3.57%), cerebral palsy (3.40%), thrombophlebitis (1.20%), recurrence (1.20%), inapropiate antidiuretic hormone secretion (1.20%) and subaracnoideal hemorrage (1.20%). The overall mortality was 10.70% and 60% of the patients which initially presented with shock and intravascular coagulation died. Autopsy findings included wide spred hemorragic lesions and intravascular thrombi in skin, mucous membranes and viscera. Adrenal hemorrhage was present in five of the six cases studied.

In a double-blind controlled trial the possible prophylactic effect of intranasally applicated DDAVP (1-desamino-8-arginine vasopressin, Minurin)--a synthetic analogue of vasopressin--is evaluated regarding the incidence of headache following lumbar puncture (LBP) in 51 patients and following pneumoencephalography (PEG) in 28 patients. DDAVP had no statistically significant effect on the incidence of headache or on the consumption of analgesics in the DDAVP-versus placebo groups (minimal relevant difference = 50%, 2 alpha = 0.05, beta = 0.50).

We used dDAVP, the 1-desamino-8-D arginine analogue of arginine vasopressin with high antidiuretic and low vasopressor potency, to treat 29 patients with neurogenic diabetes insipidus for up to 22 months. Intranasal dDAVP, 2.5 to 15 microgram twice daily, provided excellent control in most patients. Individual responses were independent of age, weight, and severity of diabetes insipidus. Resistance to dDAVP may be a rare complication of prolonged therapy. Two patients with acute postoperative diabetes insipidus were effectively treated with 5 microgram of dDAVP every 14 to 18 h. Compared to previous therapy, side effects of dDAVP were minimal (headaches in two patients), and control of symptoms and urine volume was as good as with vasopressin tannate in oil or better than chlorpropamide and lysine vasopressin nasal spray. We conclude that intranasal dDAVP, because of efficacy, long duration of action, and infrequent side effects, is the preferred treatment of neurogenic diabetes insipidus in children and adults.

The syndrome of inappropriate secretion of antidiuretic hormone is characterized by production of less than maximally dilute urine in the presence of hypotonic plasma. It may be secondary to malignant disease, central nervous system disorders, or pulmonary disease, among other conditions, or it may be idiopathic. Manifestations are those of water intoxication, eg, confusion, fatigue, nausea, headache, and neurologic signs. The pathogenesis is not completely understood. Restriction of fluid intake to obtain a negative water balance is effective treatment.

In addition to progressive endocrine dysfunction and progressive visual loss, pituitary neoplasms may annouce their presence by the more catastrophic alternative of spontaneous tumor infarction. In two patients reported, illness due to the spontaneous infraction of pituitary tumors was heralded by sudden onset of focal headache associated with diplopia. Stupor, confusion, and evidence of increased intracranial pressure occurred without subarachnoid hemorrhage or massive extrasellar extension of tumor. One patient developed inappropriate antidiuretic hormone secretion with spontaneous infarction in a large but clinically silent chromophobe adenoma. In both patients, skull x-rays suggested a long-standing intrasella mass. Both underwent prompt treatment with endocrinologic replacement therapy and subsequent successful transsphenoidal removal of voluminous, infarcted, pituitary masses.

We studied the effects of nifedipine on blood pressure and on clinical and analytical parameters in hypertensive patients. Seven male and eight female subjects (mean age of 46.27 +/- 5.38 years, range of 41-56 years) with essential arterial hypertension were given nifedipine (20 mg b.i.d.) for 3 months. Before and after treatment, history, blood pressure, and biochemical values were recorded [blood: Na, K, Ca, creatinine, uric acid, triglycerides, cholesterol, HDL cholesterol, antidiuretic hormone (ADH), and aldosterone; urine: Na, K, Ca, creatinine, ADH, aldosterone, and percentage fraction of Na, K, and Ca excreted]. After 3 months of treatment, we found (a) significant decreases in systolic (147 +/- 18 vs. 166 +/- 16 mm Hg, p less than 0.001) and diastolic blood pressure (90 +/- 8 vs. 107 +/- 8 mm Hg, p less than 0.0007), triglycerides (107 +/- 47 vs. 120 +/- 49 mg/dl, p less than 0.0007), and cholesterol (236 +/- 4 vs. 257 +/- 44 mg/dl, p less than 0.00075) in blood, and in K excretion (50 +/- 19 vs. 46 +/- 19 mEq/g of creatinine, p less than 0.0007) and excreted fraction of K (49 +/- 6% vs. 8 +/- 5%, p less than 0.0012) in urine; (b) significant increases in HDL cholesterol (65 +/- 13 vs. 58 +/- 13 mg/dl, p less than 0.001) in blood, and in Na (115 +/- 73 vs. 109 +/- 69 mEq/g of creatinine, p less than 0.0007) in urine; and (c) no significant change in the remaining biochemical parameters, or in heart rate. Secondary effects included flushing (34%), headache (20%), ankle swelling (17%), dizziness (13%), palpitations (4%), and pruritus (4%).(ABSTRACT TRUNCATED AT 250 WORDS)

This randomized controlled trial was conducted to compare the efficacy of intravenous infusion of octreotide (a synthetic long-acting somatostatin analogue) with vasopressin in 48 cirrhotic patients with endoscopically proven bleeding esophageal varices. Twenty-four patients received a continuous infusion of octreotide 25 micrograms/h for 24 h after an initial bolus of 100 micrograms and another 24 patients received a continuous infusion of vasopressin 0.4 U/min for 24 h. Bleeding was initially controlled after 6 h of drug infusion in 88% (21/24) and 54% (13/24) of the patients treated with octreotide and vasopressin respectively (p = 0.03). Complete control of bleeding after 24 h of drug infusion was achieved in 15 (63%) patients receiving octreotide and in 11 (46%) patients receiving vasopressin (p > 0.05). Side effects during drug infusion such as headache, chest pain and abdominal pain were significantly lower in the octreotide group (3/24) than in the vasopressin group (11/24). Serum gastrin and insulin levels fell significantly following octreotide infusion, but plasma glucose levels remained unchanged. Mortality related to bleeding esophageal varices was no different between the two groups. This report showed that octreotide infusion was more effective and had fewer side effects than vasopressin in initial controlling of acute esophageal variceal bleeding until an elective endoscopic sclerotherapy could be performed.

Vasopressin is a vasoactive hormone secreted from the posterior pituitary. At low concentration its role is in regulating renal water excretion, but at higher concentrations it has a number of extrarenal actions, including effects on blood flow. To investigate the role of vasopressin in spontaneous migraine, paired samples were collected from 14 subjects (a) during an acute attack of spontaneous migraine, and (b) when symptom-free for at least seven days. During an attack, vasopressin was consistently raised (median (range) 3.5 (1.2-9.6) pg/ml v 0.5 (0.5-1.1) pg/ml, p less than 0.001). The highest vasopressin concentration occurred in the only patient who vomited. The results suggest vasopressin rises during an attack of spontaneous migraine, and this may, in part, be related to emesis. In the majority, vasopressin levels only rose sufficiently to have some renal antidiuretic effect, although in some these levels could have been sufficient to cause alteration in peripheral blood flow. Release of vasopressin may be responsible for the facial pallor and antidiuresis observed in migraine.

A 46-year-old man, presenting with headache, nausea, and lassitude, was diagnosed as having diabetes mellitus and hyponatremia, and admitted to Tohoku University Hospital. Insulin treatment improved the hyperglycemia but aggravated hyponatremia, which was proved to be elicited by the inappropriate secretion of antidiuretic hormone (SIADH). An acute water load failed to suppress ADH release in the supine posture but slightly increased plasma atrial natriuretic peptide (ANP). On the other hand, plasma ADH markedly increased in response to an upright posture, accompanied by a fall in blood pressure and a rise in heart rate. After treatment with droxidopa "a sympathomimetic drug", ambulatory blood pressure gradually increased and hyponatremia disappeared. However, blood pressure and ADH responses to upright posture were not improved by treatment with the drug. Moreover, plasma ADH was still not sufficiently suppressed by acute water loading in the supine position, but plasma ANP markedly increased, thereby resulting in urinary dilution and natriuresis. These results suggest that exaggerated ADH release (SIADH) was brought about by the baroreceptor reflex stimulated by the postural hypotension, and also by the impaired osmoregulation associated with diabetic neuropathy, and that droxidopa improved cardiovascular function and increased ANP release with resultant urinary dilution and natriuresis in spite of slightly increased ADH release.

A patient with Addison's disease, treated with conventional hydrocortisone replacement, developed deep hyperpigmentation, headache and vomiting. Plasma adrenocorticotropin (ACTH) level was extremely high, showing abnormal diurnal rhythm. Suppression of ACTH with glucocorticoids was attenuated and the responses to ovine corticotropin-releasing hormone (oCRF) and lysine vasopressin (LVP) were absent. Magnetic resonance imaging (MRI) suggested an enlargement of the pituitary gland, while immunohistological examination of pituitary fragments obtained by transsphenoidal surgery revealed corticotroph hyperplasia without microadenoma. Postoperatively, plasma ACTH returned to normal and adequately responded to oCRF and LVP. Over the year since surgery, the symptoms have gradually improved and the patient has resumed normal activities.
