In contradistinction to all currently available water-soluble contrast media, metrizamide (Amipaque) is not a salt, but a substituted amide and therefore does not dissociate in solution. This unique property results in solutions of high iodine content yet with low osmolality. Metrizamide probably has a lower neurotoxicity than any other known water-soluble contrast agent. A clinical trial of metrizamide lumbar myelography in 201 patients in three clinical centres represents the first clinical assessment of this new contrast medium in the United Kingdom. The technique of the radiological procedure and the adverse reactions encountered are presented and discussed. There were no serious adverse effects: no muscle spasm or epilepsy. Minor adverse reactions--headache, vomiting and nausea occur with approximately the same frequency as with meglumine iocarmate: 43 percent of patients complained of headache. In 118 patients, the lower dorsal subarachnoid space was also examined with no increase in toxic reactions. It is concluded that metrizamide is a safe contrast medium for lumbar and lower dorsal myelography. Water-soluble media will probably largely replace oil products for these investigations. Further clinical trials are being extended to include examination of the upper dorsal and cervical subarachnoid space.

1. In a cross-over study between hydrallazine and prazosin in fifteen patients, also treated with the beta-receptor-blocking agent propranolol, 1 mg of prazosin was found to be equipotent with 30 mg of hydrallazine. 2. All patients were known to tolerate dydrallazine. In one patient prazosin treatment was discontinued because of severe headache. In four patients minor, non-persistent initial side effects were found. These might have been avoided by using a smaller starting dose. One patient fainted on the second day of prazosin treatment, probably from a micturition syncope. 3. Prazosin may be used as an alternative to hydrallazine. 4. The final status of prazosin as an anti-hypertensive drug is uncertain.20

In our field study on headache we made use of individual medical interviews and of an anterospectively programmed inventory designed for computer analysis. With regard to this aspect our investigation is the first of its kind in literature. We could find some new aspects concerning etiology and therapy of headache, among others the importance of the factor "unstable hypotension" in a general state of vascular lability, and of the factor of manual labour as a prophylactic aid against headache. Furthermore, evidence concerning the general incidence and the varying morbidity in different professional and social groups could be collected.

In industrial countries the symptoms "headache" has an incidence of about 10%, and hypertension between 20 and 25%. Both terms are summary and may be pointers to and warning signals of the most varied disease processes. While, in malignant hypertensions, and pheochromocytoma, headache is a cardinal symptom, its causal connection with permanently raised blood pressure in the "benign" forms is viewed with scepticism. The observation that hypertensives frequently complain of headaches with a maximum intensity in the early hours of the morning is connected with the fall in blood pressure with accumulation of CO2 in shallow breathing. Headache as a symptom characteristic of hypertension is frequently only facultative in nature and must be classified among the series of symptoms of sequelae. But it offers a sufficient reason to institute a selective examination programme, especially as hypertension is still the most common cause of death even today.

Dysfunction in the upper region of the cervical vertebral column is largely to be regarded as the primary disorder from which secondary anatomical substrates, especially degenerative manifestations, develop. We must shift our attention from pathomorphology to function. There are two main types of disordered vertebral function which may lead to headache in many cases: 1. hypomobility (blocking) 2. hypermobility. Suggestions are made for selective methods of examination which help the detection of disturbed function. Cinematography can be used for substantiation. Diagnostic differentiation indicates possibilities for special manipulative, physical, surgical and orthopedic treatment.

35 patients suffering from different painful conditions were treated with transcutaneous application of a slightly painful electrical stimulus. The effect was manifested in complete relief in six patients treated during an attack of migraine and in a relatively high number of other cases of headache with relief of pain. In some cases there was a long-lasting favourable effect for periods up to 8 months. For the theoretical explanation the 'gate control' theory is referred to. With respect to the practical application, the special indication in cases of chronic headache is emphasised, especially since this method avoids the risks of habit-formation or other damaging effects of drug therapy.

70% of all patients who abuse phenacetin have headache. The nephrological aspects are reported of 240 patients who were phenacetin-dependent and in an average of 19 years had consumed an average of 6 kg - up to 25 compound powders daily. The degree of renal damage depends principally on the duration and regularity of ingestion of analgesics, and less on the total quantity. One fifth of the patients were already in a condition in which a fatal outcome was inevitable when they were admitted to hospital.

If a patient suffers headaches as a result of cranial trauma, the medical expert must first of all clear up the cause of these subjective complaints. A precise diagnosis of the primary lesion and possible posttraumatic complications is a prerequisite. The differential diagnosis must take into consideration non-traumatic diseases which are also associated with headache. In the majority of cases, non-traumatic factors such as a low level of intelligence, hysterical, hypochondriacal and psychopathic personality structures and the particular conditions of the accident give rise to the development of persistent headaches after cranial injury. Difficulties in estimating the duration of headache due to trauma for the purposes of private accident insurance are pointed out and finally questions of impaired healing conditions (delayed recompensation) and "psychic" pain are dealt with.

Tick-borne encephalitis is transmitted by the tick ixodes ricinus. After the second world war an increase in the number of cases of encephalitis was observed and the neurotropic virus was isolated for the first time in 1948. Reservoir animals are mouse-like wild animals and also agricultural domestic animals. The infection is transmitted to humans through tick bites. It becomes apparent subjectively in headaches, vomiting, tiredness, giddiness and insomnia, and objectively in meningeal symptoms, extrapyramidal tremor, cerebellar ataxia, vestibular nystagmus and paresis. The treatment consists of strict rest in bed for 10 days at least and symptomatic support of the general health. Good results are obtained with antiedematous therapy with hydrocortisone or pyritinol.

Two cases of left atrial myxoma are reviewed, both presenting as embolic phenomena. Neither patient gave a history compatible with pre-existent cardiac dysfunction. Sudden collapse and subsequent right hemiplegia resulted in one patient when an embolus lodged in the left middle cerebral artery. The second patient presented with headache and transient visual obscuration in the left eye. She showed evidence of embolism to the central retinal artery, and particulate matter could be seen within the retinal arterioles. Attention is drown to the fact that echocardiography now constitutes a simple, noninvasive, and highly reliable method of making this diagnosis. The propensity for embolic tumor fragments to grow and invade cerebral arterial walls is discussed along with its possible neurosurgical significance.
