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)

Internal carotid artery dissection is a major cause of ischemic stroke in the young. Pain is the leading symptom and is associated with other focal signs such as Horner's syndrome and painful tinnitus or with signs of cerebral or retinal ischemia. We report two patients with angiographically confirmed extracranial internal carotid artery dissection presenting with cephalic pain as the only manifestation. The first patient had a diffuse headache and a latero-cervical pain lasting for 12 days, reminiscent of carotidynia. The second patient experienced an exploding headache suggestive of subarachnoid hemorrhage, which was ruled out by computed tomography of the head and cerebrospinal fluid study. These patients demonstrate that recognition of carotid artery dissection as a cause of carotidynia and headache suggestive of subarachnoid hemorrhage may permit an earlier diagnosis and possibly the prevention of a stroke through the use of anticoagulation.

Auditory brainstem evoked response-(ABR) may be affected by changes in cerebral blood flow. Apart from its primary indications for prevention of stroke and transient ischemic attacks-(TIA's), internal carotid endarterectomy-(ICE) has been shown to improve cognitive function and cause diminution of tinnitus and vertigo. A one-week postoperative ABR previous study of patients undergoing ICE demonstrated no change in ABR recordings. In order to evaluate possible late changes, we have conducted a prospective study of the delayed effects of ICE on ABR in 13 patients. No initial pathology was noted and no significant change found in any of the absolute and interpeak latencies of ABR waves.

Sudden inner ear hearing loss initially might suggest a psychogenic disorder of hearing, particularly when it is bilateral and simultaneous. The differential diagnosis includes disseminated encephalitis, syphilitic labyrinthitis and Cogan's syndrome. The history and cause of acute bilateral deafness in meningitis are easy to recognise. Furthermore, unilateral acute inner ear deafness should not be regarded as idiopathic without further consideration. A acoustic neuroma is a possible cause even of a low-tone hearing loss. More controversial is rupture of the round window membrane as a cause of sudden deafness. The deafness after epidemic parotitis obviously leads to a total unilateral hearing loss in every case. Even labyrinthine apoplexy with loss of hearing and vestibular function can be caused by a tumour of the cerebellopontine angle. Idiopathic sudden deafness should be defined as an acute sensory hearing loss whose anatomical basis in an acute vascular endolymphatic hydrops of unknown cause. The sudden deafness affects only one ear; tinnitus and brief vertigo can be accompanying symptoms. A sudden hearing disorder due to other causes should be distinguished from idiopathic lesions.

1. Tinnitus is seldom recorded in the clinical database of the elderly, despite the fact that next to hearing loss, tinnitus is the most commonly reported ear problem by the elderly population. 2. Common problems of the elderly that demand special counseling and teaching skills of the nurse are decreased tolerance to tinnitus due to coexistent complex morbidity, social problems, and losses; worry that the tinnitus is a sign of an impending crisis, such as stroke, brain tumor, or insanity; and boredom with excess time with little to do but to listen to one's tinnitus. 3. Tinnitus in aging is a symptom that is usually due to an identifiable disease, and is rarely of subjective type, high-pitched quality, chronic, irreversible, idiopathic, and bilateral. 4. The common causes and aggravating factors about tinnitus in aging can provide the clues to effective nursing-initiated measures, many of which are simple household activities or personal interactions.

We have treated six patients with carotid body tumours in the period from 1972 to 1988. All patients had a neck mass on presentation. In addition one patient complained of tinnitus and another was noted to have Horner's syndrome. The diagnosis was confirmed by ultrasound and angiography in all cases. Five patients subsequently underwent successful surgical resection. At the time of surgery one of the tumours was found to be locally invasive. One elderly patient was deemed unfit for surgery and was managed non-surgically with a satisfactory outcome. A review of the literature reveals that surgery is still the preferred mode of treatment although preoperative embolization may be a useful adjunct. Although the incidence of peroperative stroke has gradually been reduced from that found in earlier series, injury to the cranial nerves remains high and is the main hazard of surgical management. The improved results of surgical resection in more recent reports support the view that these tumours should be treated in units with expertise in vascular surgery of the neck.

The acute central nervous and cardiovascular effects of the local anesthetics ropivacaine and bupivacaine were compared in 12 volunteers in a randomized double-blind manner with use of intravenous infusions at a rate of 10 mg/min up to a maximal dose of 150 mg. The volunteers were all healthy men. They were familiarized with the central nervous system (CNS) toxic effects of local anesthetics by receiving a preliminary intravenous injection of lidocaine. The infusions of ropivacaine and bupivacaine were given not less than 7 days apart. CNS toxicity was identified by the CNS symptoms and the volunteers were told to request that the infusion be stopped when they felt definite but not severe symptoms of toxicity such as numbness of the mouth, lightheadedness, and tinnitus. In the absence of definite symptoms, the infusion was stopped after 150 mg had been given. Cardiovascular system (CVS) changes in conductivity and myocardial contractility were monitored using an interpretive electrocardiograph (which measured PR interval, QRS duration, and QT interval corrected for heart rate) and echocardiography (which measured left ventricular dimensions from which stroke volume and ejection fraction were calculated). Ropivacaine caused less CNS symptoms and was at least 25% less toxic than bupivacaine in regard to the dose tolerated. Both drugs increased heart rate and arterial pressure. Stroke volume and ejection fraction were reduced. There was no change in cardiac output. Although both drugs caused evidence of depression of conductivity and contractility, these appeared at lower dosage and lower plasma concentrations with bupivacaine than with ropivacaine.(ABSTRACT TRUNCATED AT 250 WORDS)

Embolic and thrombotic infarction in the territory of the posterior cerebral artery (PCA) is described with emphasis on the stroke and cerebrovascular features rather than special neurological syndromes. Of 47 cases of obstruction at the distal bifurcation of the basilar artery, 43 (95%) were consistent with embolism. The clinical categories and pathological findings are presented. Local embolism, vertebral distal-stump embolism, the dynamics of hemorrhagic infarction and embolus-in-transit are briefly described. The prodromal manifestations of PCA thrombotic occlusion include photopsias, hemianopic blackouts, headache, transient episodes of numbness, episodic lightheadedness, spells of bewilderment and rarely tinnitus. Recognition of these may allow prevention of a stroke. Prodromal photopsias did not closely resemble the scintillating displays of migraineurs. When the stroke occurred, visual complaints usually predominated. A sensory deficit occurred in one-third of cases. In 25 cases of memory impairment the dominant hemisphere was involved in 24. The kinds of visual hallucinations, simple and formed, are described.

Pulse-synchronous tinnitus suggests a vascular etiology and is deemed rare by the otologic literature. During the period 1978-1985 we evaluated 20 patients with the sole or initial complaint of pulsatile tinnitus. Fourteen patients had objective pulsatile tinnitus, perceived by the patient and the examiner alike, and 6 had subjective pulsatile tinnitus, perceived by the patient only. Angiographic findings in patients with objective pulsatile tinnitus included dural or pial arteriovenous malformations, occlusive disease of the intra- or extracranial carotid arteries from atherosclerosis or dissection, panarterial ectasia, and venous sinus thrombosis. Most of the patients with subjective pulsatile tinnitus had normal evaluations, but other possible causes of subjective pulsatile tinnitus included a carotid occlusion and pseudotumor cerebri. Pulsatile tinnitus is an uncommon symptom produced by a variety of causes. Given the abnormalities present in our series, we would recommend intraarterial digital subtraction angiography or conventional angiography in the evaluation of objective pulsatile tinnitus and intravenous digital subtraction angiography for subjective pulsatile tinnitus. Increased intracranial pressure must also be considered.

The angiographic, clinical, and genetic characteristics of fibromuscular dysplasia (FMD) are reviewed in 37 patients (mean age 48 years) selected from a pool of 4000 angiograms of carotid or vertebral arteries. FMD was a neglected pathogenic factor in 28 patients with hemorrhagic or ischemic cerebral lesions. The aneurysms found in 19 patients had conventional appearance and were mainly located in the internal carotid or middle cerebral arteries and on the same side as the most affected cervical artery, which suggests that aneurysms and FMD are pathogenically related. A clinical syndrome is presented where headache, ECG-abnormalities, hypertension, mental distress, tinnitus, vertigo, arrhythmia, TIA, and syncope are frequent components. Hemicrania, sometimes combined with ipsilateral Horner's Syndrome, was found in patients with advanced lesions in the carotid artery of the same side. An associated occurrence of stroke in pedigrees, especially among young and middle aged females, indicates that FMD in the majority of cases in inherited as an autosomal dominant trait with reduced penetrance in males.
