This investigation was undertaken to define the "adequate" sodium concentration in the dialytic fluid allowing to maintain a stable plasma effective osmolality during dialysis. Isonatric dialysate is shown to miss this aim by inducing a predictable postdialytic hypernatremia. To avoid this effect a new approach was made. 17 clinically stabilized patients, previously dialyzed over a period of at least 2 years with a dialysate sodium concentration of 133 mEq/l, underwent dialysis with the "adequate" sodium concentration in the dialysate for over 3 years. During dialysis cramps, headache, hypotension, hypertensive crises and postdialytic weakness were reduced in frequency and nearly disappeared. No deterioration in blood pressure control occurred and improvement in some general parameters (hematocrit, glucose and insulin metabolism, well-being) was reported after prolonged treatment.

A 3 1/2-year-old girl with a huge optic glioma was reported. On February 26, 1978, she was hospitalized for signs of increased intracranial pressure, namely headache, vomiting and consciousness disturbance. Before admission she did not complain of her visual disturbance. A huge mass lesion in the subfrontal-suprasellar region was found by neuroradiological examination. The operation was performed on March 7, 1978, and the tumor arising from the right optic nerve, about 170 grams in weight, was totally removed in piecemeals. Histopathological diagnosis was pilocytic astrocytoma. Immediately after operation diabetes insipidus and hypernatremia developed, but two months later these symptoms disappeared. Post-operative CT scan demonstrated no mass lesion in the subfrontal-suprasellar region. After radiation therapy, she was discharged with slight left hemiparesis on August 31, 1978. Though her right eye was blind, visual acuity remained 0.2 in the left eye. No other neurologic deficits could be found.

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 forty four year-old woman had had an amenorrhea-galactorrhea syndrome for 3 months when a Korsakoff's syndrome with headache suddenly appeared. Neuroradiological investigations revealed a hematoma involving the anterior part of the IIIrd ventricle. After a short period of neurogenic hypernatremia the lesion disappeared with the development of a spontaneous ventriculocisternostomy. Simultaneously, the Korsakoff's syndrome decreased until it went off almost completely, but a diabetes insipidus appeared and the hyperprolactinemia remained unchanged. Four years later, those are the only symptoms which are still present. This case, particular by its aetiology and evolution, illustrates well the possibility of functional Korsakoff's syndromes.

There have been numerous accounts of women on ovulation inhibitors developing hypertension or reactifying or intensifying previous hypertension. Concerning frequency of significant hypertension in pill users, there are reports varying from .66% (or even 0%) to 19%. The time interval between start of medication and manifestation of hypertension also varies according to different sources from 7 days to 5 years, with the critical point usually around 6-8 weeks. Degree of hypertension after ovulation inhibitors ranges from mildly significant increases in systolic and/or diastolic blood pressure to malignant hypertension with irreversible kidney insufficiency. Early observable symptoms of hypertension include migrainelike headaches and rapid weight gain (sodium and water retention). After discontinuation of the medication, normal blood pressure is attained either within a few days or after 6-8 months. If normalization of blood pressure does not occur spontaneously there may be other causes (e.g., secondary vascular disorders). Concerning pathogenesis of ovulation-inhibitor-related hypertension, changes (increases) in the renin-angiotensin-aldosterone system are assumed to play a major role (almost all women on the pill exhibit elevated renin-angiotensin-aldosterone activity). Sodium retention may also be determinative. Many clinical and laboratory studies have demonstrated that it is the estrogen content of ovulation inhibitors that is responsible for the increased plasma renin activity. The study recommends: 1) women who wish oral contraceptive therapy should give careful family and personal histories and be tested for blood pressure before and during treatment (monthly, then after 6 months twice yearly); 2) careful supervision is indicated for women with high blood pressure or other cardiovascular disorders in their history, present or former kidney disorders, arterial hypertension, pregnancy toxemias, adipositas, or diabetes mellitus; 3) abnormal weight gain may be an early symptom; 4) if any rise in blood pressure is observed, ovulation inhibitor medication should be discontinued immediately; and 5) ovulation inhibitor-induced hypertension should be considered in differential diagnosis in young women with arterial hypertension.

An association between primary mediastinal germ cell tumors and hematologic malignancies has been recognized since 1985. We present a patient with a suprasellar germ cell tumor and an associated leukemia. A 20-year-old black female presented in December 1987 with a 6-month history of headaches and weight loss, confusion, polyuria, and polydipsia. Evaluation revealed hypernatremia, normal neurologic examination except poor recall, and an enhancing inhomogeneous suprasellar mass on cranial computed tomography. Biopsy of the mass diagnosed a dysgerminoma, which was treated with craniospinal radiation. In February 1988, the patient developed pancytopenia, which resolved with discontinuation of cimetidine and phenytoin. She did well until June 1988 when she presented with skin lesions over the trunk and extremities. Skin biopsy revealed a leukemic infiltration. She was admitted with a WBC 1,500/microliter (without blasts), Hb 11.6 g/dl, PLT 210,000 microliter. Bone marrow biopsy revealed hypercellularity with 50% blasts, demonstrating mixed-lineage acute myeloblastic leukemia (myelomonocytic-M4; megakaryoblastic-M7). The patient was induced with a standard Ara-C/daunorubicin regimen. Two weeks postinduction, she became septic and expired. An autopsy demonstrated leukemic involvement of the spleen, liver, bone marrow, and skin, without residual dysgerminoma. This represents the first reported case of suprasellar dysgerminoma associated with a mixed-lineage leukemia not related to chemotherapy.

A 34-year-old man with AIDS was admitted to the hospital with a one-week history of cough, chest pain, and fever. Radiography revealed a cavitating left upper lobe lesion. Two weeks later he developed a headache associated with a contrast enhancing lesion in the right parietal lobe. The patient had a progressive downhill course, developing atrioventricular block and hypernatremia. Neuro-ophthalmologically, there was a mild facial droop, "hand motions" vision with presumed bilateral cytomegalic inclusion retinitis, and signs of a mesencephalic syndrome, including lid retraction. Discussions center on the differential diagnosis of the central nervous system disease and the obligative recommendations the neuro-ophthalmologist must be willing to make.

Non-typhoid salmonellosis remains a common infective illness. We studied 77 consecutively admitted children aged 1 month to 15 years in order to determine frequency of antecedents, the strain of the isolated organisms, clinical findings, frequency of complications and the adequacy of management. The presentation and severity of the illness were compared between younger than two and older children. Salmonella typhimurium was isolated in 65% of the cases. Two thirds of the tested strains were multiresistant to antibiotics. Non-typhoid salmonellosis usually occurred in the form of acute gastroenteritis: in only 4% of the cases it presented as pyrexia of unknown origin without gastrointestinal symptoms. 30% of the cases had been exposed to one or more antimicrobial agents within four weeks before the date of their stool culture. Only 30% had been breast fed. Previously diagnosed cow's milk protein intolerance resulted to be present in 14% of the less than two years old children (p < 0.02). Abdominal pain and headache were found more frequently in older children (p < 0.02). Protein C reactive values were significantly higher in this age group (p < 0.05). 25% of the children were mildly or moderately dehydrated. Hypernatremia was uncommon. 31% of the cases were treated with antibiotics: the antimicrobial treated children presented diarrhoea for longer period (p < 0.05) and they remained admitted for longer time (p < 0.00).(ABSTRACT TRUNCATED AT 250 WORDS)

A case of sinus thrombosis occurring during combination chemotherapy with CDDP and VP-16 (PE) for a suprasellar germ-cell tumor is presented. A 5-year-old girl developed polyuria, polydipsia and headache in April, 1991 and became unconscious on May 10, 1991, when MRI and CT demonstrated a suprasellar tumor and marked hydrocephalus. After a ventriculo-peritoneal shunt operation, radiotherapy and two courses of PE therapy were carried out. During the second course of PE therapy, diabetes insipidus became quite difficult to control and severe hypovolemic hypernatremia developed. While it was being treated, the patient developed a clonic convulsion of her left extremities and visual disturbance. CT scan demonstrated a right parietal hemorrhagic infarction and IV-DSA suggested thrombosis of the superior sagittal sinus. Laboratory data disclosed DIC. The main cause of sinus thrombosis in this patient was considered severe dehydration. It is also possible that cisplatin and steroid played a role. In addition to these, dysfunction of hypothalamus, which is one of the regulatory centers of the plasma concentration of factor VIII, may have contributed to the acceleration of blood coagulation. This case re-emphasized the importance of preventing dehydration and monitoring the blood coagulation fibrinolytic system during PE therapy in patients with a suprasellar germ-cell tumor accompanied with diabetes insipidus.

We describe an 18-year-old female who complained of general weakness, nausea, vomiting, headache, and lightheadedness. On physical examination, she was euvolemic without visual or neurological deficits. The striking biochemical abnormality was hyponatremia (125 mmol/l). This hyponatremia met the laboratory diagnostic criteria for the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Two litres of normal saline were given per day for 4 days and this did not correct her hyponatremia. A spontaneous diuresis (6.6 l) developed in 1 day, causing a rise in her PNa of 26 mmol and a final PNa of 152 mmol/l. Magnetic resonance imaging revealed a dumbell-shaped intrasellar and suprasellar cyst. During transsphenoidal surgery, a Rathke's cleft cyst (RCC) lined with columnar epithelium containing mucoid material was resected. We speculate that the growing RCC may have produced critical compression over the stalk, thus contributing to the transition from SIADH with hyponatremia to transient central diabetes insipidus with hypernatremia.
