Cerebral infarction was documented by arteriography and serial computed cranial tomography (CT) in four young adults (ages 16 to 32 years) with migraine. In one case, posterior cerebral artery occlusion produced a deep parietotemporal infarct. The other three cases all had frontotemporal infarcts (one hemorrhagic) in the territory of the middle cerebral artery, without major arterial occlusion. Two infarcts produced lasting neurologic deficits; one was associated with mild, transitory symptoms, and one was asymtomatic. Laboratory investigations in two cases revealed no hematologic or cardiovascular predisposition to cerebrovascular disease. Cerebral infarction, as revealed by CT, may be more prevalent in "complicated" migraine than is generally appreciated. Such lesions may or may not develop in chronologic and anatomic relationship to the headache, and may involve either large or small arteries. The prognosis for functional recovery, based on this limited sample, seems favorable.

A sudden cervical extension-flexion (whiplash) can cause a temporomandibular pathology with a direct and indirect mechanism of action. A total of 24 patients of both sexes who had undergone acute cervical trauma, which had led to masticatory dysfunction of a meniscal or algomyo-facial type, were examined. The most frequent signs and symptoms were regional pain, a qualitative and quantitative change in movements, cephalea, and articular noise. A complete condylo-meniscal block was observed in three cases. Concomitant radiographic tests using a trans-cranial projection confirmed clinical findings. A multidisciplinary individual therapeutic approach ensured complete functional recovery; prognosis varied with regard to cephalalgia which is related to the individual's psycho-behavioural substrate. The paper stresses the importance of early diagnosis and targeted treatment in order to prevent symptoms from becoming chronic thus making the disorder a disability which is difficult to treat.

A report on 8 patients with idiopathic multiple cranial neuropathy is presented. The syndrome consists of headache, facial pain and diplopia preceding the onset of cranial nerve palsy. The cranial nerves most frequently involved were the third, fifth and seventh. All patients were treated with corticosteroid therapy. The symptoms were self-limiting in their course and corticosteroid therapy appeared to hasten recovery of function. Only in a few cases a noticeable neurological deficiency remained. Differential diagnosis and etiological considerations are discussed.

The clinical manifestations and computed tomographic (CT) findings of small intracerebral haematomas (ICHs) were studied in 31 consecutive cases which comprised 6% of 520 cases of non-traumatic, non-neoplastic ICH confirmed by CT in a 3-year period. A small ICH was defined by CT as a sharply demarcated high density area with the maximum dimension not exceeding 20 mm and on no more than two contiguous 10-mm scan sections. The ages ranged from 50 to 85 years, being between 50 and 69 in about two thirds. Twenty-nine patients (93%) were hypertensive. The haematoma was in the capsulothalamus (9 cases), thalamus (6 cases), capsuloputamen (6 cases), subthalmus (2 cases), internal capsule (2 cases) pons (4 cases), midbrain (1 case), and cerebellum (1 case). Headache (4 cases) and vomiting (3 cases) were rare, whereas dizziness was rather frequent (16 cases). None had loss of consciousness. The essential clinical manifestations were sensorimotor deficits in 13 cases, pure motor hemiparesis in 6, pure sensory disturbance in 4, and involuntary movements in 2. Five patients with haemorrhage in the brain stem presented with various syndromes. None of the 31 cases had a fatal outcome directly due to the small haemorrhagic stroke. Two patients had recurrent stroke; a small, deep infarct in 1 and a large haemorrhage in the other. Full neurological and functional recovery was made in 17 cases (56.7%), recovery with mild sequelae in 7 (23.3%) and little recovery in 6. Poor recovery was related to the location (pons), the age (above 75 years), and the presence of involuntary movements. Some clinical features common to lacunar infarcts and small ICHs were discussed, and the possibility of a combination of these two conditions in a same hypertensive patient was raised. Small ICH as a type of benign, non-fatal stroke is not infrequent in communities where the incidence of hypertensive ICH is relatively high. CT scanning in the early stage of stroke even for patients with mild neurological symptoms may enhance the detection rate of such small ICHs.

Head trauma is a significant health care problem. Treatment of the head trauma patient requires assistance from many different disciplines in order to maximize recovery of function. The fact that one fourth or more of head trauma patients are impaired in recovery because of psychological factors suggests that appropriate treatment programs are not being implemented in the United States. Organic factors can produce many of the symptoms reported by head trauma patients. However, these factors are more likely to contribute indirectly to such symptoms, and their influence declines as recovery progresses. Recovery from head trauma follows identifiable stages. During the period of coma, the extent of the organic disturbance is sufficient to impair brain-stem functions. Once consciousness is regained, there is a period of gross memory dysfunction. Coma and posttraumatic amnesia represent the acute phase of recovery, during which patients are often hospitalized and receive intense medical care. Once gross functions return, intense medical care is no longer needed. However, the head trauma victim has not returned to a premorbid status at this point. This phase, between recovery from posttraumatic amnesia and stabilization or recovery of premorbid level of functioning, can best be considered the chronic phase of recovery. The chronic phase of recovery is characterized by defects in cortical functions, including impaired intellectual functions, memory weakness, difficulty in processing complex stimuli, slowed reaction time, and other deficits. While these deficits may not be profound, they do correlate with the severity of injury and the degree of eventual recovery. This observation lends further credence to the presence of underlying disturbance of neurologic functioning. During this chronic phase of recovery, head trauma patients may have made good physical recovery and may feel well enough to return to work. However, they frequently process less information and may experience difficulty with tasks that require attention and effort. Such patients tire rapidly and experience stress symptoms, such as headaches and irritability. These symptoms correspond to environmental demands, but they also reflect underlying neurogenic weaknesses. Emotional sequelae that often emerge during the chronic phase of recovery may be related to the patient's reduced ability to cope with environmental stress. Therefore it is not surprising that emotional sequelae appear to correspond more to environmental demands than to severity of injury per se.(ABSTRACT TRUNCATED AT 400 WORDS)

Among the various methods of application techniques in low level laser therapy (LLLT) (HeNe 632.8 nm visible red or infrared 820-830 nm continuous wave and 904 nm pulsed emission) there are very promising "trigger points" (TPs), i.e., myofascial zones of particular sensibility and of highest projection of focal pain points, due to ischemic conditions. The effect of LLLT and the results obtained after clinical treatment of more than 200 patients (headaches and facial pain, skeletomuscular ailments, myogenic neck pain, shoulder and arm pain, epicondylitis humery, tenosynovitis, low back and radicular pain, Achilles tendinitis) to whom the "trigger points" were applied were better than we had ever expected. According to clinical parameters, it has been observed that the rigidity decreases, the mobility is restored (functional recovery), and the spontaneous or induced pain decreases or even disappears, by movement, too. LLLT improves local microcirculation and it can also improve oxygen supply to hypoxic cells in the TP areas and at the same time it can remove the collected waste products. The normalization of the microcirculation, obtained due to laser applications, interrupts the "circulus vitiosus" of the origin of the pain and its development (Melzak: muscular tension > pain > increased tension > increased pain, etc.). Results measured according to VAS/VRS/PTM: in acute pain, diminished more than 70%; in chronic pain more than 60%. Clinical effectiveness (success or failure) depends on the correctly applied energy dose--over/underdosage produces opposite, negative effects on cellular metabolism. We did not observe any negative effects on the human body and the use of analgesic drugs could be reduced or completely excluded. LLLT suggests that the laser beam can be used as monotherapy or as a supplementary treatment to other therapeutic procedures for pain treatment.

The purpose of this study was to analyze the long-term mortality, functional recovery and long-term complications of cerebral vein and dural sinus thrombosis (CVDST) admitted to Portuguese hospitals. A follow-up of symptomatic CVDST admitted to Portuguese hospitals since 1980 was performed. Fifty-one patients (retrospective cases) were re-evaluated during 1996; 91 consecutively admitted patients from 6/1995 to 6/1998 were followed up to 1999. In 1996, 4 (8%) of the retrospective cases had died (3 patients died in the acute phase), 4 (8%) could not be reached, 33 (64%) had recovered completely (Rankin 0 or 1) and 3 (6%) were dependent. The prospective cases had a mean follow-up of 1 year: 6 (7%) patients died in the acute phase, one (1%) died during follow-up, 75 (82%) recovered completely, and only 1 (1%) was dependent. For the prospective cases, worsening after admission (OR = 18.2; 95% CI = 2.9-112.4) and encephalopathy as the presenting syndrome (OR = 7.1; 95% CI = 1.2-40.9) predicted death or dependency, while absence of aphasia (OR 6.7, 95% CI = 1.6-33) and no worsening after admission (OR = 5.9; 95% CI = 1.6-20) predicted total recovery. During follow-up of the prospective cases, 4 (5%) patients had thrombotic events, 8 (10%) patients experienced seizures, 9 (11%) complained of severe headaches and 1 patient suffered severe visual loss. The long-term functional prognosis of patients with CVDST was fairly good with complete recovery in the majority of cases. However, these patients had a moderate risk of further thrombotic events and seizures.

Most people with episodic tension-type headache (TTH) treat themselves with over-the-counter analgesics. In the absence of clear evidence of dose-related efficacy of the two most commonly used analgesics, aspirin (acetylsalicylic acid) and paracetamol (acetaminophen), this study compared two doses of each with placebo. In a double-blind, double-dummy, randomized parallel-groups comparative trial, 638 consenting subjects aged 16-65 years with episodic TTH (but not migraine) by IHS criteria were recruited from the UK general population by advertisement. They treated one episode of moderate or severe TTH with a single dose of 500 or 1000 mg aspirin, 500 or 1000 mg paracetamol or placebo. The primary objective was to compare aspirin 1000 mg with placebo, and the primary end-point was subjective pain relief (total or worthwhile) 2 h after treatment ('response'). Additionally, pain intensity on a 100-mm visual analogue scale and functional impairment were monitored regularly for 4 h and at 24 h, although rescue medication was allowed after 2 h. The analysis was of the intention-to-treat population of 542 who took treatment (all providing outcome data). Treatment groups were matched at baseline. Aspirin 1000 mg (75.7% response rate; P = 0.0009) and to a lesser extent aspirin 500 mg (70.3%; P = 0.011) and paracetamol 1000 mg (71.2%; P = 0.007), but not paracetamol 500 mg (63.8%; P = 0.104), were statistically more effective than placebo despite a high placebo-response rate (54.5%). Outcome was not affected by headache intensity at baseline. Secondary end-points including functional recovery (by median times of 4.0-13.5 h) were consistent with these findings, although a minority of subjects recorded long-duration functional impairment (37-54 h). Adverse events reported by 13.4-18.9% of subjects were mild or moderate, and transient. No safety concerns arose.

Forty-nine cases of dissection of the internal carotid and vertebral arteries are reported in our prospective multicenter study of 35 men and 14 women, with a mean age of 46.77 years. (range 17-60 years). We evaluated etiology, clinical manifestations, investigative techniques, and treatment. Thirty-one patients had so-called spontaneous dissections, although in the remaining 18 minimal or obvious trauma was considered as the etiological factor. Headache and neck pain occurred in 32 patients (65.3%). Local neurological manifestations were present in 15 patients (30.6%) and ischemic cerebral symptoms were present in 41 patients (83.6%). The most-relevant of the diagnostic tools are duplex sonography, magnetic resonance angiography, and angiography. Anticoagulation with heparin followed by warfarin was the treatment of choice in most of our patients. Complete recovery is reported in 14 patients (28.5%); 41 patients showed cerebral ischemic symptoms, of which 13 (26.5%) had good functional recovery. In 28 (57.1%), the NIHSS score decreased from 6.68 to 3.31 during hospitalization.

Botulinum toxin type A, a protein long used in the successful treatment of various dystonias, has a complex mechanism of action that results in muscle relaxation. At the neuromuscular junction, the presynaptic nerve ending is packed with synaptic vesicles filled with acetylcholine, and clustered at the tip of the folds of the postsynaptic muscle membrane are the acetylcholine receptors. Synaptic vesicles fuse with the membrane in response to an elevation of intraneuronal calcium concentration and undergo release of their transmitter by exocytosis. Intracellular proteins that contribute to the fusion of the vesicles with the plasma membrane during exocytosis include synaptosomal protein with a molecular weight of 25 kDa (SNAP-25); vesicle-associated membrane protein (VAMP), also known as synaptobrevin; and syntaxin. Through their proteolytic action on these proteins, botulinum toxins prevent exocytosis, thereby inhibiting the release of acetylcholine. There are 7 serotypes of this toxin-A, B, C1, D, E, F, and G-and each cleaves a different intracellular protein or the same target at distinct bonds. The separate cleavage sites in SNAP-25 for botulinum toxin types A and E contribute to their dissimilar durations of muscle relaxation. This report describes the molecular basis for the inhibition by botulinum toxins of neuroexocytosis and subsequent functional recovery at the neuromuscular junction.
