Spinal myoclonus following a peripheral nerve injury: a case report

Spinal myoclonus is a rare disorder characterized by myoclonic movements in muscles that originate from several segments of the spinal cord and usually associated with laminectomy, spinal cord injury, post-operative, lumbosacral radiculopathy, spinal extradural block, myelopathy due to demyelination, cervical spondylosis and many other diseases. On rare occasions, it can originate from the peripheral nerve lesions and be mistaken for peripheral myoclonus. Careful history taking and electrophysiological evaluation is important in differential diagnosis

The comparative effectiveness of migraine preventive drugs: a systematic review and network meta-analysis

OBJECTIVE: While there are several trials that support the efficacy of various drugs for migraine prophylaxis against placebo, there is limited evidence addressing the comparative safety and efficacy of these drugs. We conducted a systematic review and network meta-analysis to facilitate comparison between drugs for migraine prophylaxis. METHODS: We searched MEDLINE, EMBASE, CENTRAL, and clinicaltrials.gov from inception to August 13, 2022, for randomized trials of pharmacological treatments for migraine prophylaxis in adults. Reviewers worked independently and in duplicate to screen references, extract data, and assess risk of bias. We performed a frequentist random-effects network meta-analysis and rated the certainty (quality) of evidence as either high, moderate, low, or very low using the GRADE approach. RESULTS: We identified 74 eligible trials, reporting on 32,990 patients. We found high certainty evidence that monoclonal antibodies acting on the calcitonin gene related peptide or its receptor (CGRP(r)mAbs), gepants, and topiramate increase the proportion of patients who experience a 50% or more reduction in monthly migraine days, compared to placebo. We found moderate certainty evidence that beta-blockers, valproate, and amitriptyline increase the proportion of patients who experience a 50% or more reduction in monthly migraine days, and low certainty evidence that gabapentin may not be different from placebo. We found high certainty evidence that, compared to placebo, valproate and amitriptyline lead to substantial adverse events leading to discontinuation, moderate certainty evidence that topiramate, beta-blockers, and gabapentin increase adverse events leading to discontinuation, and moderate to high certainty evidence that (CGRP(r)mAbs) and gepants do not increase adverse events. CONCLUSIONS: (CGRP(r)mAbs) have the best safety and efficacy profile of all drugs for migraine prophylaxis, followed closely by gepants.info:eu-repo/semantics/publishedVersio

Structured headache services as the solution to the ill-health burden of headache: 1. Rationale and description

In countries where headache services exist at all, their focus is usually on specialist (tertiary) care. This is clinically and economically inappropriate: most headache disorders can effectively and more efficiently (and at lower cost) be treated in educationally supported primary care. At the same time, compartmentalizing divisions between primary, secondary and tertiary care in many health-care systems create multiple inefficiencies, confronting patients attempting to navigate these levels (the “patient journey”) with perplexing obstacles. High demand for headache care, estimated here in a needs-assessment exercise, is the biggest of the challenges to reform. It is also the principal reason why reform is necessary. The structured headache services model presented here by experts from all world regions on behalf of the Global Campaign against Headache is the suggested health-care solution to headache. It develops and refines previous proposals, responding to the challenge of high demand by basing headache services in primary care, with two supporting arguments. First, only primary care can deliver headache services equitably to the large numbers of people needing it. Second, with educational supports, they can do so effectively to most of these people. The model calls for vertical integration between care levels (primary, secondary and tertiary), and protection of the more advanced levels for the minority of patients who need them. At the same time, it is amenable to horizontal integration with other care services. It is adaptable according to the broader national or regional health services in which headache services should be embedded. It is, according to evidence and argument presented, an efficient and cost-effective model, but these are claims to be tested in formal economic analyses

Primer saplanıcı başağrısı : iki olgu sunumu

Primer saplanıcı baş ağrısı; saniyeler süren nadir ve şiddetli bir başağrısıdır. Ağrı özellikle trigeminal sinirin birinci dalı boyunca hissedilir ve günde bir veya birkaç günde bir gelen bir veya birkaç kez tekrarlayan saplanma atakları şeklinde ortaya çıkar. Primer saplanıcı başağrısı yıllardır bilinmekle birlikte tanı için klinisyenin sorgulaması gereklidir. Primer saplanıcı başağrısının tanısını koymada diğer olası nedenlerin dışlanması önemlidir. İndometazin klasik olarak ilk tedavi seçeneğidir ancak olguların %35'e yakını tedaviye direnç gösterir. Son yıllarda cyclooxygenase-2 inhibitörleri, gabapentin, nifedipine, parasetamol, ve melatonin tedavisinin etkinliğini destekleyen çalışmalar bildirilmektedir.Primary stabbing headache is an excruciating and relatively rare type of headache that typically lasts for only a few seconds. Pain is predominantly felt in the distribution of the first division of the trigeminal nerve and can be experienced as single stabs or as a series of stabs, either per day or every few days. Primary stabbing headache has been well-defined for decades and must be kept in mind during diagnosis. Exclusion of other possible causes is necessary in order to establish diagnosis. Indomethacin has classically been considered the first treatment option, but therapeutic failure occurs in up to 35% of cases. Recent studies have suggested that cyclooxygenase-2 inhibitors, gabapentin, nifedipine, paracetamol, and melatonin are also effective treatments

Fabry disease mimicking multiple sclerosis

Fabry disease is an X-linked recessive lysosomal storage disorder resulting from the deficiency of alpha-galactosidase. This disease causes endothelial vasculopathy and affects multiple organ systems. Hemizygous male patients represent the classical renal, cardiac and neurological symptoms of disease. Heterozygous female carriers are frequently asymptomatic, but cerebrovascular events in females are as frequent as in males. Even if rarely seen, neurological damage is an important cause of morbidity. Severe neurological signs that are due to multifocal small vessel occlusions may be present without major thrombosis

The effect of contact lens wear on the excitability of blink reflex circuit: A prospective controlled study

This study determined whether the use of contact lenses constitutes a model for adaptive alterations. We included 8 volunteers using contact lenses and 11 volunteers as control group. The blink reflex (BR) recovery was measured using the paired- pulse technique. No differences were observed between groups in initial R2 recovery at 200, 400, 800 and 1000 ms intervals. The 600 ms measurements were lower in the contact lens group (P = 0.037). There was a decrease at 600 ms in the 1st week, which reached the value of the control group in the 1st month (P = 0.049). It was concluded that rigid gas- permeable contact lens use does not cause an increase in the excitability of the interneurons that affect the BR cycle
