An 11-year-old twin girl was admitted to hospital with a 24-hour history of profuse sweating, tachycardia, and hypertension after a single dose of imipramine. She was subsequently found to have a right adrenal phaeochromocytoma. To our knowledge, this is the first reported case of tumour provocation by imipramine.

The patient, a manic depressive who was treated with lithium for three years, suddenly developed severe neurotoxicity and a glomerulonephritis-like syndrome. The author believes that the lithium toxicity was facilitated by hot weather with excessive sweating, gall bladder pathology with fever, and decreased water and salt intake. The patient improved except for a persistent hypertension. Propranolol not only improved the hypertension but alleviated a lithium-induced tremor as well.

We report the case of a 42-year-old Zairian male who presented with paroxysmal attacks of hypertension accompanied by spontaneous recurrent hypothermia and profuse sweating of unknown origin. Routine and extensive examination failed to indicate a usual cause of arterial hypertension or for periodic hypothermia. Based on the hypothesis of an epileptic center influencing both the thermoregulatory and the vasomotor mechanisms, an anticonvulsant treatment was successfully installed. The present study makes a correlation between the present condition and certain neurologic abnormalities described in the literature.

A 64-year-old right hemiplegic woman, who had been treated for hypertension for 15 years, was admitted to our hospital. Neurologic examination on admission disclosed right hemiplegia and motor aphasia; however, ophthalmoparesis, pupillary abnormality, and blepharoptosis were not evident. Excessive sweating on the right side of the body, which was most marked on the face, was observed. Amount of sweating on the left side of the body was normal. Unilateral hyperhidrosis persisted for more than 2 months. MRI revealed hemorrhagic infarctions in the left basal ganglia, internal capsule, thalamus, hypothalamus, and medial part of the cerebral peduncle. 123I-IMP SPECT disclosed hypoperfusion in the left striatum, thalamus, occipital cortex, and right cerebellar hemisphere. Cerebral angiography revealed arteriosclerotic changes in the basilar artery, but that the left posterior cerebral artery and its branches were not occluded. Unilateral persistent hyperhidrosis is rare after ischemic stroke. Hypothalamic lesion was thought to be responsible for the hyperhidrosis in this patient. As the hypothalamus receives its blood supply from the posterior cerebral artery, unilateral persistent hyperhidrosis may be an important sign of cerebral infarction in the posterior cerebral artery region.

We present a case report on a 35-year-old patient in whom a malignant sympathetic paraganglioma of the organ of Zuckerkandl was the cause of severe hypertension with excessive perspiration at night. Since curative surgery was not possible medical treatment was initiated. Interferon alfa 2b (Intron A, Essex Pharma) and the somatostatin-analogue SMS 201-995 (Sandostatin, Sandoz) had no effect on catecholamine production and progression of the tumor. Treatment with alpha-methyl-para-tyrosin (MPT, [Metyrosin], Demser, MSD) turned out to be an effective and well tolerable therapy in this patient with peritoneal carcinosis. Clinical and hormonal progression of the paraganglioma resumed only after two years of therapy, which constitutes the longest documented period of time of successful MPT treatment. The superior efficacy of MPT in our patient should encourage postoperative medical treatment with MPT in malignant pheochromocytoma or malignant paraganglioma, particularly when the tumor turns out to be resistent to alpha blocking drugs.

Micturition difficulties associated with unstable hypertension, tachycardia and profuse sweating could be a sign of pheochromocytoma of the urinary bladder. Of all pheochromocytomas, 10-36% are located extradrenally, in which case they are also referred to as paragangliomas, and 1-3% are found in the urinary bladder. The case history of a 44-year-old female patient with typical symptoms is described. Diagnosis required not only CT, NMR, excretory urography and MIBG scintigraphy, but also hormonal analyses. Histology reveals malignancy in up to 20%; it is thought that focal invasions of tumor into vessels and destruction of connective tissue might be pathognomonic. A precise history and careful diagnosis are necessary before a pheochromocytoma of the bladder can be disclosed and treated.

Pheochromocytoma was diagnosed in a female patient aged 26 with paroxysmal arterial hypertension (AH), profuse sweating, headache, anxiety, tachycardia, transit arrhythmia, high urinary norepinephrine (NE), epinephrine (E) and vanillyl mandelic acid (VMA). Urography with intravenous Odiston revealed a relatively large tumor at the upper pole of the right kidney. Complete removal of the tumor in a 2-step surgical procedure brings apparent clinical and hormonal recovery for 6 years, but then clinical and hormonal relapse occurs through ganglionary metastasis and tumor at the basis of the mesentery. Removal of the metastasis and tumor brings again improvement in the clinical and hormonal picture.

Three boys were treated for arteritis of the aorta and great vessels and bilateral renal artery stenosis. One presented at age 6 months with failure to thrive, excessive sweating, and vomiting: hypertension and cardiac failure were subsequently diagnosed. The two older boys (7 and 14 years) presented with symptomless hypertension. The clinical and angiographic findings in the three patients suggest that the illness may have been Takayasu's arteritis, which should be included in the differential diagnosis of hypertension in infancy and childhood. Renal autotransplantation was performed in all three patients with good results. Early renal autotransplantation may reduce the morbidity associated with this disease.

Two cases of sympathetic paraganglioma are reported: one, benign, in a 20-years old woman with arterial hypertension and attacks of excessive sweating; the other, malignant and with bone metastases, in a 44-years old woman. Both were diagnosed by scintigraphy, using meta-iodobenzylguanidine as radionuclide. This new radiopharmaceutic agent has recently been introduced for the detection of phaeochromocytomas, but it seems to be a general tissue marker of catecholamine uptake and storage. Its use as a therapeutic compound may also be envisaged.

A 31 year-old inhabitant of French Guiana was prescribed mercuric iodide per os for two and a half months. Shortly before the end of the treatment he developed fasciculations in the trunk and particularly the lower limb muscles, distal painful paresthesias with vasomotor disorders, episodes of excessive perspiration and palmoplantar erythema, moderate fluctuating hypertension, progressive loss of weight and irritability with insomnia. Clinical and electrical signs of neuropathy were lacking. The clinical picture was that of Morvan's fibrillary chorea with acrodynia, the conditions of onset strongly suggesting a mercurial intoxication. Blood and particularly urine mercury levels were elevated. Administration of dimercaprol (BAL) considerably increased urinary excretion of mercury and there was progressive improvement and finally recovery after two months of BAL treatment. This case exemplifies the possible co-existence of fibrillary chorea and acrodynia. Whereas in many cases of fibrillary chorea a precise etiology cannot be determined, the affection can be induced by mercury as by gold administration. The fact that cases of fibrillary chorea due to mercury poisoning are rarely reported may be the result of individual patient hypersensitivity or particular metabolic absorption and excretion features of mercury. This case cannot be included within the continuous activity syndrome of muscle fibers described by Isaacs, since muscle contractures were absent and there was associated acrodynia. Moreover, there was no latent polyneuropathy, in spite of the intense fasciculations. It must be concluded, therefore, that in spite of its rarity fibrillary chorea should keep its semiologic autonomy.
