The majority of cases of central diabetes insipidus are still pathogenetically unclear (idiopathic). Atherosclerotic cholesterol emboli might be partly responsible for some of these idiopathic cases. A 54-year-old woman with known aortic valve stenosis and a history of a transitory ischemic attack presented with sudden-onset polyuria and polydipsia of up to eight l/d, which had started acutely with headaches. She had been treated with lithium for 3 years because of cyclothymic depression. Plasma sodium was in the upper normal range (142-148 mmol/l). Hypertonic saline infusion during lithium therapy revealed a normal threshold of thirst and resetting of vasopressin secretion (osmotic threshold > 300 mosmol/l), whereas vasopressin reserve was normal. Lithium withdrawal led to an even greater delay of vasopressin release upon hypertonic saline infusion (> 310 mosmol/l). Pituitary function tests revealed a normal anterior pituitary function. MR imaging of the hypothalamo-hypophyseal region showed a normal hypothalamic region and a highly intensive neurohypophyseal signal in the T1-weighted image. The patient responded well to desmopressin. We suggest that in this rare case clinical symptoms as well as biochemical findings like impairment of AVP release might be related to a minor structural hypothalamic damage by a vascular lesion, caused, for example, by an atheromatous (cholesterol) embolism in the hypothalamic region responsible for integration of osmoreceptor function and AVP-secretion. The patient's atherosclerosis and aortic stenosis might be responsible for this event.

A deficit of mitochondrial energy metabolism may play a role in migraine pathogenesis. We found in a previous open study that high-dose riboflavin was effective in migraine prophylaxis. We now compared riboflavin (400 mg) and placebo in 55 patients with migraine in a randomized trial of 3 months duration. Using an intention-to-treat analysis, riboflavin was superior to placebo in reducing attack frequency (p = 0.005) and headache days (p = 0.012). Regarding the latter, the proportion of patients who improved by at least 50%, i.e. "responders," was 15% for placebo and 59% for riboflavin (p = 0.002) and the number-needed-to-treat for effectiveness was 2.3. Three minor adverse events occurred, two in the riboflavin group (diarrhea and polyuria) and one in the placebo group (abdominal cramps). None was serious. Because of its high efficacy, excellent tolerability, and low cost, riboflavin is an interesting option for migraine prophylaxis and a candidate for a comparative trial with an established prophylactic drug.

Renal artery stenosis or occlusion causing the hyponatremic-hypertensive syndrome has been rarely reported. Our impression, however, was that the disorder is not uncommon. Case records from patients in one city (population 350 000) presenting between 1980 and 1997 with hypertension, hyponatremia, and evidence of renal ischemia were scrutinized. Thirty-two patients fulfilling inclusion criteria were identified. Admission supine arterial pressures were high (mean 228/124 mm Hg), but there was a vigorous fall in pressure on standing (26/12.7 mm Hg recorded in 27 patients). Mean plasma concentrations of sodium (129.7 mmol/L) and potassium (2.7 mmol/L) were low, and 24-hour urine protein excretion was elevated in 19 of 26 patients. Twenty-two of the 32 patients were female, the majority were asthenic, and all but 5 were smokers. Symptoms precipitating hospitalization were headache, clouding of consciousness, confusion, weakness, weight loss, thirst, and polyuria. Plasma renin levels, measured in 20 patients, were elevated in most cases and correlated inversely (r=-0.63, P<0.01) with the plasma sodium concentration. The hyponatremic-hypertensive syndrome in patients with renal ischemia is not rare: Rather, it is underreported. It tends to affect elderly asthenic women who smoke heavily. Stimulation of renin release from the ischemic kidney is probably central to the pathophysiology. The syndrome deserves better recognition to ensure appropriate investigations and management.

Migraine headache and panic disorder are two conditions that have a number of underlying physiological and psychological abnormalities in common. The temporal relationship between the occurrence of migraine headache and panic attacks could be different, however. According to our observations, some migraine subjects develop panic attacks with the typical symptoms (palpitation, dyspnea, anxiety/fear, shiver, sweating, polyuria) on the "peak" of their attacks. This variant of migraine without aura was conditionally defined as "panic migraine". Here we describe two patients suffering from migraine without aura in whom migraine was associated with the typical panic attack. It is suggested that a pronounced autonomic dysregulation along with marked psychological abnormalities could be responsible for the constellation of migraine and panic symptoms during one episode. Taking into account the previously obtained results, it is concluded that compared to "pure" migraine, "migraine associated with panic attacks" is characterized by a severe course, marked autonomic and emotional disturbances during pain-free intervals, seriously impaired quality of life, and requires a specific therapeutic approach.

Nephropathia epidemica (NE) is a prevalent zoonosis throughout Europe and is caused by the Puumala type of hantavirus. The incidence of NE varies in a cyclic fashion, with peaks occurring every 3rd to 4th year, coinciding with peaks in vole populations. The clinical course of NE is generally milder than haemorrhagic fever with renal syndrome caused by hantaviruses in other parts of the world. Typically, NE has a sudden onset with fever, headache, backpain and gastrointestinal symptoms. However, severe complications, e.g. gastrointestinal haemorrhage, occur and fatal cases have been reported. Renal involvement is prominent and manifests as initial oliguria and later as marked polyuria. Tests of renal function show pronounced glomerular and tubular involvement. Vaccine against Puumala virus infection as well as specific treatment for NE are still lacking.

We studied the clinical presentation by age of 36 children with craniopharyngioma, and outcome by height and body mass index (BMI). Presenting symptoms included headache (51.4%), vomiting (31%), visual disturbances (22.9%), polyuria and/or polydipsia (17.1%), delayed puberty (19.4%), short stature (13.8%), and precocious puberty (2.7%). Growth deceleration was overlooked, as was diabetes insipidus (actual rate, 52% for both). Delayed puberty was observed in all patients of appropriate age. Mean height standard deviation score (SDS) at admission was significantly lower than mean target height SDS (p = 0.004), while mean final height SDS was similar (p = 0.14). BMI SDS at last follow-up was similar to mean parental BMI SDS. We conclude that although endocrinopathies are present in most patients with craniopharyngioma, they are rarely the reason for referral. While affected prepubertal children have non-endocrine complaints, most adolescents are referred because of delayed puberty. Diabetes insipidus may be more prevalent in craniopharyngioma than previously reported. When patients with hypothalamic obesity are excluded, mean BMI SDS remains within normal range and is influenced mostly by parental BMI SDS.

Four patients who had ingested large amounts of phenacetin-salicylate medications were studied during a 12-month period. Renal failure had progressed slowly over a number of years. All patients took the drug because of psychogenic headache. Considerable skill was required to elicit the history of drug habituation. The major features of the nephropathy were multiple episodes of metabolic acidosis, minimal proteinuria, pyuria but no bacteriuria, and polyuria and polydipsia early in the course of drug ingestion. Papillary necrosis was not a prominent clinical feature of this series. Discontinuation of drug ingestion by one patient was associated with recovery of a considerable degree of renal function. Preliminary experimental evidence obtained in the dog suggests that salicylate impaired the efficiency of the counter-current multiplier by decreasing sodium transport in the ascending limb of Henle, and decreased the permeability to water of the distal convoluted and collecting tubule; phenacetin had no such effect.

Brown tumor is a focal lesion of the bone caused by primary or, less commonly, secondary or tertiary hyperparathyroidism (HPT). While the mandible is the most frequently involved bone in the head and neck region, atypical involvement of the cranium in the area of the sphenoid sinus is exceedingly rare. In the literature, a unique case of brown tumor of the sphenoid sinus was reported in a patient with primary HPT. We present a case of sphenoid sinus and occipital bone brown tumor associated with primary HPT. A 47-yr-old woman presented a 2-yr history of headaches, dizziness, diffuse body and articular pain, fatigue, and a 6-month history of intermittent nausea and vomiting, polydipsia, and polyuria. Magnetic resonance imaging (MRI) demonstrated an expansive mass lesion in the sphenoid sinus with erosion of the sellar floor and medial wall of the right orbit, and expansion in the medulla of bone. Examination of biopsy specimens obtained from sphenoid sinus mass confirmed the diagnosis of brown tumor. The biochemical laboratory studies showed elevation of parathyroid hormone and confirmed the diagnosis of primary HPT. Excision of a parathyroid adenoma affected the metabolic status into normalizing. At the follow-up of 12 months postoperatively, the size of sphenoid sinus brown tumor decreased and the mass of occipital bone disappeared. In conclusion, this is a first report of primary HPT masquerading as a destructive fibrous sphenoid sinus brown tumor associated with a mass lesion of occipital bone and hypercalcemia in the literature.

Craniopharyngioma is one of the leading causes of hypothalamic-pituitary dysfunction in childhood, caused either by the tumor itself or the consequences of treatment. Tumor management in terms of recurrence rate, quality of life and complications is still controversial. Sixty-six patients with craniopharyngioma at pediatric age were reviewed for symptoms, signs, types of treatment, recurrence rates, complications, and endocrinological outcome. The majority of symptoms was related to the neurological system. Complaints only affecting the endocrinological system were seen in 6% of patients. The most frequent complaints were headache and vomiting (74.2%). The main endocrinological complaints were polyuria and polydipsia (15%), and lassitude (10.6%). Although short stature was a symptom in 9.1% of patients, it was a finding in 39.7% of patients. Plain skull X-rays raised the suspicion of intracranial tumor in more than 90% of children with craniopharyngioma. Recurrence rates were independent of the extent of tumor removal (total or subtotal). The frequency of endocrine dysfunction increased significantly after treatment. The most frequent hypothalamic-pituitary dysfunction was growth hormone deficiency (100%) and gonadotropin deficiency (80%). Hypothyroidism was diagnosed in 74% of patients. The frequency of hypothalamic-pituitary dysfunction was not affected by the extent of tumor removal. Radiotherapy did not increase the frequency of endocrine dysfunctions further. In conclusion, growth follow-up in childhood seems to be an important indicator of craniopharyngioma in early diagnosis. Radiotherapy and extent of tumor removal - either total or subtotal - did not influence endocrine outcome.

Through a case of sellar and suprasellar tuberculoma which presented with central diabetes insipidus, the authors report the frequency of pituitary tuberculoma, its physiopathology, clinical presentation hormonal and radiological findings thus management and evolution. A 42 years old woman, with a history of erythema nodosum, presented with polyuria polydipsia (PUPD), amenorrhea and galactorrhea. Endocrine investigations showed central diabetes insipidus, elevated serum prolactin levels and cortisol failure. Magnetic resonance imagining scans (MRI) revealed a nodular thickening of the pituitary enlargement and loss of posterior pituitary hypointensity signal. Etiologic inquiry has removed the diagnosis of sarcoidosis, Langerhan's histosis, autoimmune hypophysitis and sellar metastasis. The history of erythema nodosum, the positivity of tuberculin skin test and the presence of koch bacillus in the bronchial fluid after culture led to a diagnosis of tuberculosis. Treatment was started with four drug antitubercular chemotherapy regimen for 2 months, and tow drug antitubercular chemotherapy regimen for 16 months. This treatment is associated with hydrocortisone, desmopressin nasal spray and bromocriptine. Under treatment, there was an improvement in clinical condition, disapearence of headache, PUPD and galactorrhea thus normalization of prolactin. A follow-up MRI, 8 months later, showed that pituitary lesion has been completely removed, suggesting our clinical and biology presumption. Pituitary tuberculosis is rare, however, when encountered, they may present a diagnostic difficulty. Accurate diagnosis and management is important because pituitary tuberculoma is curable.
