The findings of 152 patients with proven primary hyperparathyroidism are reportedmthe purpose of the analysis was to find difference between the various clinical manifestations of the disease. Furthermore the occurrence of acute hyperparathyroid crisis in our series as well as in the literature are described. 65.8% of the patients were females, 34.2% were males. The leading symptom in 98 patients (group I) were kidney stones and in 23 patients (group II) cystic bone disease. Both manifestations of the disease occurred in only 7 patients (group III) and no symptoms related to the kidneys or to the bones occurred in 24 patients (group IV). Because of the difference of the clinical manifestations the additional data were analyzed for each group separately and compared with each other. There was no difference in the mean serum calcium levels for all four groups, however, patients of group I were on the average younger, the duration of the disease was longer and the weight of the parathyroid adenoma was lower compared to the other three groups, Data are presented regarding calcium excretion, phosphate clearance and tubular reabsorption of phosphate for each group. At operation single or multiple adenoma formation was present in 133 patients, whereas diffuse hyperplasia was found in 17 and carcinoma in 2 other patients. 46 of the adenomas were found in an atypical anatomical localisation. This observation is responsible for the many unsuccessful or second explorations of the neck; The weight of the adenomas varied between 0.1 and 23.5 g. The most difficult diagnosis was that of diffuse hyperplasia. The sucess of the surgical intervention was usually established in over 80% of the cases within 24 to 48 hours after the operation with a significant fall of serum calcium. There ist still no definite explanation for the variability of the clinical manifestations of primary hyperparathyroidism. Parathyroid hormone determinations on larger numbers of patients are not yet published. The assumption, that different hormones or peptide fragments are reposible for the different action on bone and kidney is discussed; In our series of 152 patients acute hyperparathyroid crisis occurred eight times. Our findings are compared to the other well documented cases in the literature. Main symptoms were nausea, vomiting, abdominal pain and different states of cerebral dysfunction. Most of the patients had calcium levels over 16 mg/100 ml. Partial renal insufficiency with elevated blood urea and phosphate retention was found in over 50% of the cases. Overall mortality of all cases with acute parathyroid crisis is 52.5%. The pathogenesis of acute hyperparathyroidism and the implications of high calcium levels are discussed. According to our own experience hypercalcenia can be controlled with an intensive therapeutic program and emergency operation for acute parathyroid crisis is no longer necessary.

We have reported the case of a 58-year-old woman with cerebral palsy who experienced a persistent, generalized syndrome of dystonia and rigidity (tardive dystonia-parkinsonism) while being treated for vomiting with metoclopramide in combination with prochlorperazine. This syndrome was more severe than is typically seen in drug-induced extrapyramidal syndromes and may have contributed to her death. The extreme severity of this disorder was probably related to the use of a combination of dopamine antagonists in a patient who had premorbid cerebral dysfunction. Although dopamine antagonists should always be used with caution in individuals with cerebral dysfunction, this particular combination of antiemetics should probably be avoided in such patients.

A series of 12 patients with cerebellar infarcts diagnosed by computerized tomography are reviewed. The clinical features of cerebellar infarctions cover a wide spectrum, mimicking symptoms and signs from an acute labyrinthitis to a rapidly expanding posterior fossa mass lesion with brain stem and cerebral dysfunction. Two patients were asymptomatic and three showed signs of cerebellar dysfunction only. Three patients had evidence of brain stem dysfunction with cranial nerve palsies accompanying the cerebellar deficit. Two presented a pseudovestibular form with sudden onset of nausea, vomiting, rotary dizziness and ataxia. A pseudotumoral form with intracranial hypertension was found in two cases, in which softening tissue acts as a rapidly expanding posterior foss mass lesion. It is difficult to identify the exact artery involved in a cerebellar infarct because of the collateral circulation and connections between the three major arteries. Atherosclerosis and general decrease in blood flow can be regarded as the most likely factors precipitating focal cerebellar infarction. Surveillance is necessary during the first days with anti-edematous therapy. Rapid deterioration of consciousness should be considered a sign of increasing intracranial pressure progressing with the development of hydrocephalus. If necessary, surgical decompression by external drainage or by direct access to the posterior fossa can be carried out.

Body movements during sleep were observed in 14 full-term sick newborn infants such as perinatal asphyxia, purulent meningitis, meconium aspiration syndrome, melena, porencephaly, and hydranencephaly. Five newborn infants who had recovered from transient vomiting were examined as control. Infants with minimally depressed background EEG showed an increase of generalized movement (GM) and localized tonic movement (LTM) in quiet sleep. Hydranencephalic infants revealed an increase of generalized phasic movement (GPM) in active and quiet sleep. On the other hand, a decrease or an absence of body movements was observed in infants with severe EEG abnormalities such as moderate, marked and maximal depression. Hydranencephalic and porencephalic neonates showed a decrease of LTM in active sleep. One infant with purulent meningitis, showing markedly depressed EEG, revealed GPM-like movements of much longer duration. The follow-up study revealed that the absence of body movements or the increase of GPM might indicate a very poor outcome, whereas the presence of LTM, even in a small amount, suggested the preservation of cortical functions. The increase of body movements was also considered to correlate with sleep disturbance and served to indicate a brain dysfunction.

A thiopental test 2 weeks after insertion of intracranial electrodes may be used to evaluate patients with refractory epilepsy for surgical therapy. Barbiturates normally produce beta activity on the electroencephalogram. The absence of this response in a monitored brain region implies focal cerebral dysfunction. We describe a technique used to perform this test and the resultant morbidity. The thiopental test consists of intravenous injection of thiopental, 25 mg, every 30 s until either corneal reflexes are abolished, 1,000 mg of thiopental has been administered, or adverse events occur. In children, the dose is adjusted to approximately 0.3 mg/kg of thiopental every 20 s. A retrospective chart review was performed on 104 patients who underwent thiopental tests at the University of Pittsburgh Epilepsy Center. Records were systematically reviewed for thiopental dose, mean arterial blood pressure, heart rate, oxygen saturation in arterial blood, time to responsivity, need for airway intervention, and occurrence of nausea or vomiting. Thirty-six patients developed upper airway obstruction which required jaw lift maneuver, six patients were given 1,000 mg of thiopental without loss of corneal reflexes, and one patient briefly sustained an arterial saturation of 67%. Five patients exhibited electrographic seizures with clinical seizures evident in two patients. No permanent effects were evident in any patient as a consequence of the test. We conclude, with appropriate monitoring and personnel, that the thiopental test, as described, can be performed safely with acceptable morbidity.

Migraine is caused by intermittent brain dysfunction. Attacks result in severe unilateral headache with nausea, vomiting, photophobia, phonophobia and general weakness. The prevalence of migraine is 12 to 20% in women and 8 to 12% in man. Treatment of an acute attack is done by antiemetics in combination with analgesics. Severe migraine attacks are treated with ergotamine or sumatriptan. Parenteral treatment is performed most efficiently and safely with i.v. ASA. Frequent and severe attacks require prophylaxis. Drugs of first choice are metoprolol, propranolol, flunarizine and cyclandelate. Substances of second choice are valproic acid, DHE, pizotifen, methysergide and magnesium. Homeopathic remedies are not superior to placebo. Nonpharmacological treatment consists of sport therapy and muscle relaxation techniques.

Patients with anorexia nervosa or bulimia nervosa may try to compensate weight gain due to binge eating by purging: vomiting or use of diuretics, laxatives or diet pills. Purging may reduce the body weight through volume depletion, but has hardly any effect on the food uptake. Frequent vomiting is revealed by enlargement of the submandibular and parotid glands and rise of the serum amylase. Use of laxatives leads to electrolyte imbalances, lesions of intestinal mucosa and chronic obstipation. Physical effects of diuretics are dehydration and electrolyte imbalance; oedema may be a sign of their discontinuation. Frequent or major effects of purging are: disorders of cardiac conduction (caused by hypokalaemia), insults and cerebral dysfunction (both due to hyponatraemia). A normal serum potassium concentration does not exclude intracellular hypokalaemia; accordingly, electrocardiography is indicated.

There is increasing evidence of permanent sequalae from acute organophosphate poisoning. We report on accidental diazinon overexposure with acute organophosphate poisoning through cutaneous absorption and inhalation followed by persistent neurological effects. In addition, we observed skeletal and endocrine effects likely attributable to the diazinon poisoning. A family of seven was exposed to diazinon in June 1999 over a two-day period. The pesticide company mistakenly used diazinon to heavily spray the inside of the home instead of permethrin. The applicator applied the pesticide over the entire surface of the floor, carpeting, furniture, and clothing in closets to eradicate an infestation of fleas. Acute symptoms in the family members included headaches, nausea, skin irritation, runny nose, and vomiting. The family was first evaluated at 3 months and then 3 years after the acute poisoning. There were persisting neurological symptoms of memory loss, decreased concentration, irritability, and personality changes of varying degrees in all family members. Objective neurological findings of impaired balance, reaction time, color vision, slotted pegboards and trials making were present in the three older children who could be tested. Neuropsychological evaluation revealed evidence of organic brain dysfunction in all seven family members. Bone growth difficulties are present in four of five children. One child has delayed menarche.

In 3 patients, a woman aged 58 and 2 men aged 61 and 58, respectively, who presented to the Emergency Clinic with sudden antegrade and retrograde amnesia, the diagnosis 'transient global amnesia' (TGA) was made. In the first and the last patient the TGA was preceded by a Valsalva-like manoeuvre, i.e. vomiting and tying the shoelaces while bending over and holding his breath, respectively. Until recently, TGA was assumed to have three possible causes: arterial ischaemia (transient ischaemic attack; TIA), migraine and epilepsy. A fourth and more recent hypothesis is cerebral venous stasis. This is in accord with the haemodynamic changes that have been described as a provoking factor in TGA. A Valsalva-like manoeuvre increases the intrathoracic pressure, followed by venous reflux in the internal jugular vein. The resultant cerebral venous congestion can cause temporary ischaemia of mesiotemporal structures, such as the hippocampus, and lead to transient cerebral dysfunction. Recent studies support this haemodynamic pathogenesis. The aetiology of TGA is probably multifactorial, with cerebral venous stasis probably playing an important role. There is still no good explanation for the observation that a causative factor usually leads to a TGA in the same person only once.
