127 patients with pulseless disease were compared with normal persons of the same age group, localization and distribution of the occlusions, risk factors and complaints were analysed. Pulseless disease occurs predominantly in elderly men. In all patients, occlusions were found more often in the left supraaortic branches than in the right side. In men, stenosis of the left subclavian artery, in women stenosis of the right carotid artery is found most frequently. In most cases only one aortic branch was diseased. Vertigo, tinnitus and deafness was encountered in 32 patients (25.20%) but only in 3 persons of the control group (2.36%). In 29 of these 32 patients uni- or bilateral stenosis of the carotid artery was present. In the cases with unilateral stenosis (16) tinnitus and deafness could be localized to the respective side. In the other cases an isolated stenosis of the subclavian artery was found. In the 32 patients with otogenic symptoms hypertension was the risk factor number 1. Early diagnosis by only auscultation and palpation as well as medical treatment is pointed out.

Most frequently encountered causes of intractable pain and intractable medical problems, including headache, post-herpetic neuralgia, tinnitus with hearing difficulty, brachial essential hypertension, cephalic hypertension and hypotension, arrhythmia, stroke, osteo-arthritis, Minamata disease, Alzheimer's disease and neuromuscular problems, such as Amyotrophic Lateral Sclerosis, and cancer are often found to be due to co-existence of 1) viral or bacterial infection, 2) localized microcirculatory disturbances, 3) localized deposits of heavy metals, such as lead or mercury, in affected areas of the body, 4) with or without additional harmful environmental electro-magnetic or electric fields from household electrical devices in close vicinity, which create microcirculatory disturbances and reduced acetylcholine. The main reason why medications known to be effective prove ineffective with intractable medical problems, the authors found, is that even effective medications often cannot reach these affected areas in sufficient therapeutic doses, even though the medications can reach the normal parts of the body and result in side effects when doses are excessive. These conditions are often difficult to treat or may be considered incurable in both Western and Oriental medicine. As solutions to these problems, the authors found some of the following methods can improve circulation and selectively enhance drug uptake: 1) Acupuncture, 2) Low pulse repetition rate electrical stimulation (1-2 pulses/second), 3) (+) Qi Gong energy, 4) Soft lasers using Ga-As diode laser or He-Ne gas laser, 5) Certain electro-magnetic fields or rapidly changing or moving electric or magnetic fields, 6) Heat or moxibustion, 7) Individually selected Calcium Channel Blockers, 8) Individually selected Oriental herb medicines known to reduce or eliminate circulatory disturbances. Each method has advantages and limitations and therefore the individually optimal method has to be selected. Applications of (+) Qi Gong energy stored paper or cloth every 4 hours, along with effective medications, were often found to be effective, as Qigongnized materials can often be used repeatedly, as long as they are not exposed to rapidly changing electric, magnetic or electro-magnetic fields. Application of (+) Qi Gong energy-stored paper or cloth, soft laser or changing electric field for 30-60 seconds on the area above the medulla oblongata, vertebral arteries or endocrine representation area at the tail of pancreas reduced or eliminated microcirculatory disturbances and enhanced drug uptake.(ABSTRACT TRUNCATED AT 400 WORDS)

Hypo- and hypertension, arrhythmias, bradycardia extending to cardiac arrest with circulatory failure, pneumothorax, allergic reactions with or without anaphylactic shock, production of methaemoglobin, vomiting, vertigo, disorientation, acoustic and visual disorders, tinnitus, slurred speech, muscle contractions, unconsciousness, and epileptic seizures are well-known complications associated with local anaesthetics. We have observed an additional central nervous system complication: a case of transient, total motor aphasia (Broca aphasia) in a 50-year-old patient after axillary blockade of the brachial plexus. Possible causes such as type and dosage of local anaesthetic or a transient ischaemic attack in the area of the prerolandic artery are discussed and related to the literature. Ultimately, however, it is still not apparent why this complication could appear although there was no overdosage intravascular injection, or abnormality of the pulse or blood pressure, and why its manifestation was limited to a motor aphasia.

We describe 10 patients with idiopathic intracranial hypertension who did not have papilledema. Idiopathic intracranial hypertension without papilledema, although rarely reported, may well be a clinically important headache syndrome. Historical and demographic features of patients with idiopathic intracranial hypertension without papilledema are similar to those of patients with papilledema. Obese women with chronic daily headache and symptoms of increased intracranial pressure, pulsatile tinnitus, history of head trauma or meningitis, an empty sella on imaging studies, or a headache that is unrelieved by standard therapy should have a diagnostic lumbar puncture. Findings from laboratory and neurologic investigations are normal in most patients with idiopathic intracranial hypertension without papilledema. Initial management should include removal of possible inciting agents, weight loss if applicable, and standard headache therapy. Lumbar puncture and diuretic therapy should precede a trial of corticosteroids. Surgery (lumboperitoneal or ventriculoperitoneal shunt or perhaps optic nerve sheath fenestration) may be indicated for prolonged incapacitating headache that is not responsive to medical management or lumbar puncture.

In this study, auditory brainstem-evoked responses were conducted on 28 patients with otologic symptoms (pulsatile tinnitus, hearing loss, aural fullness) secondary to benign intracranial hypertension syndrome. Abnormalities consisting mainly of prolonged interpeak latencies were detected in one third of these patients. It is speculated that the pathophysiologic mechanisms responsible for these auditory brainstem-evoked abnormalities are stretching-compression of the cochlear nerve and brainstem caused by the intracranial hypertension and/or primary edema of the same structures due to the benign intracranial hypertension syndrome itself. Normalization or improvement was noticed in the majority of the patients after management. Since the number of patients in this study is small, it is felt that the diagnostic and prognostic value of this test needs further evaluation.

Previously, the authors reported that objective pulsatile tinnitus can be the major or only manifestation of benign intracranial hypertension. This report updates the authors' experience with 31 patients managed over the past 7 years. Benign intracranial hypertension should be suspected in all patients with pulsatile-objective tinnitus, especially when the patient is a young, obese female with headaches and/or visual disturbances. Papilledema and small ventricles or an empty sella on computerized tomography are almost diagnostic. The diagnosis is confirmed by elevated spinal fluid pressure on lumbar puncture. In such patients, angiography is not indicated. Furosemide and acetazolamide are very effective. Ligation of the internal jugular vein is contraindicated.

It was observed that in hypertension hearing is severely damaged. By analysis of the otological symptomatology in 50 hypertonic patients (42 women, 8 men) a bilateral hearing disorder was revealed in 47 subjects, a unilateral one in three subjects, otoscopy revealed dilatation of the artery supplying the handle of the malleus or even hyperaemia of Schrapnell's membrane. The patients reported low-frequency tinnitus, vertigo, pressure in the ears pain in the ears, headache, weather-dependence of complaints. In the initial stages roof-shaped type of audiometric curve was found, in the group were 45% mixed types of deafness. If during hypertension sodium is retained and the extracellular volume is enlarged, then in the inner ear the volume of perilymph increases in particular and this leads to impaired conduction through the inner ear fluids with affection of high and low frequencies, disorders of the conduction function of the fenestrae with the conduction component on the audiogram. Hypertension is for the organ of hearing an important risk factor in pre-disposed subjects with and affection of the inner ear is equally malignant and has a similar pathological background as glaucoma.

The prevalence of tinnitus was examined in a group of 270 persons from an average cross-section of the population of Ulm. For statistical reasons we selected eight groups aged exactly 10, 20, 30, 40, 50, 60, 70, and 80 years. Thirty-one percent of those examined have already noted the presence of tinnitus at some point in time. Temporary tinnitus lasting not longer than 5 min. was reported in 19.5% and longer lasting tinnitus in 11.5% of cases. The highest incidence of 55% was found at the age of 20. The previously assumed age dependent increase in the incidence of tinnitus was seen only in the longer lasting type (5 min). The age dependent incidence of tinnitus was statistically correlated to audiogram, blood pressure, grade of physical activity, noise stress, and vertigo. The low incidence of tinnitus in presbyacusis (11%) differs from previous studies. Hypertension was associated with a lower incidence of tinnitus than normotension or hypotension.

Tinnitus synchronous with the pulse is usually caused by vascular processes. The best-known sources are vascular temporal bone tumours and arteriovenous malformations. Vascular tinnitus due to anomalies of the venous system is an entity of its own and may be associated with anomalies of the jugular foramen. The present investigation shows that a high jugular bulb facilitates the occurrence of pulsatile tinnitus, albeit not necessarily leading to a bruit. Imaging methods are necessary not only in the assessment of the jugular bulb but also in the diagnosis of intracranial hypertension, which can present by a typical venous tinnitus.

Patients with transient ischemic attack (TIA) in the vertebrobasilar artery more often complain of disturbance of equilibrium, such as vertigo or dizziness, than of auditory disorders, such as hearing impairment or tinnitus. The author induced TIA in rabbits by injecting adenosine diphosphate (ADP) into the right vertebral artery. Observations of rotatory nystagmus have shown that a peak level of directional preponderance appeared 1 minute after injection of ADP (0.3mg/kg b.w.) and continued for more than 4 minutes. On the other hand, the amplitude of auditory brainstem responses (ABRs) presented no significant changes following the injection of ADP (0.5mg/kg b.w.). However, greater amounts of ADP (1.0 and 2.0 mg/kg b.w.) were found to reduce the amplitude of ABR-waves, although significant reduction was observed for only less than 1 minute. This change was represented by flattening of the later part of the waves, with the first wave much less affected. Electrocochleogram (E. Coch. G.) have also demonstrated a transient reduction in amplitude 10 seconds after injection of ADP (4.0mg/kg b.w.) with correspondingly rapid recovery. In cases of hypertension due to noradrenaline load or trimethaphan-induced hypotension, reduced amplitudes were more profound and continued longer, returning to its normal range within 1 minute. Differences in susceptibility between the equilibrium system and auditory system in TIA of the vertebrobasilar artery are discussed.
