Objectives:To evaluate the effectiveness of rescue treatment (intravenous immunoglobulin or plasma exchange) in patients with Guillain–Barre syndrome who did not respond or deteriorated after the initial management with intravenous immunoglobulin.Methods:We performed a retrospective review of the medical records of patients who responded poorly or did not respond to intravenous immunoglobulin treatment. The disability parameters of those who received second-line treatment with intravenous immunoglobulin or plasma exchange (20 patients) were compared with those who did not receive second-line treatment (19 patients).Results:There was a statistically significant improvement in disability scores at 1 month in the patients who received the rescue treatment (p = 0.033). However, there was no significant difference in the disability scores at 3 and 6 months, or in length of intensive care unit stay.Conclusion:Our study showed that a second course of treatment to carefully selected patients may be beneficial
A 39-year-old Philipino man presented with acute onset fever and headache. Neurological examination was normal except for neck stiffness. There was no history of chest pain, cough or breathlessness. Cerebrospinal fluid (CSF) showed a mild increase in protein with normal sugar and lymphocytic pleocytosis. CSF PCR for herpes simplex and varicella zoster virus was negative. He developed acute right haemiplegia a week after hospitalisation. MRI showed acute infarct in the left centrum semiovale. His angiogram showed aneurysm in the left subclavian artery and aortic arch. The mycoplasma antibody test came positive with very high titres, while rest of the workup was negative. He was treated with azithromycin and his symptoms improved completely.He was asymptomatic on follow-up after a month. His repeat immunoglobulin G mycoplasma antibody titre showed elevation. Mycoplasma infection is a treatable cause of meningoencephalitis and stroke secondary to vasculitis. Arterial aneurysms are known to occur with mycoplasma infection although rare.
We report the case of a 59-year-old Arab woman who was presented with acute onset of neck pain followed by quadriparesis, paraesthesias of lower limbs and incontinence of urine. Examination revealed asymmetric sensorimotor quadriparesis with sensory level at T1, establishing a clinical diagnosis of transverse myelitis. Cervical and thoracic spinal MRI showed enhancing T2/fluid attenuated inversion recovery (FLAIR) hyperintense lesion extending from C4 to C7 level in addition to long-segment lesion extending the whole of the spinal cord. She was known to have rheumatoid arthritis for the past 20 years and has been on etanercept for the past 8 years and methotrexate since past 3 years. Etanercept was stopped and she was treated with methylprednisolone followed by oral steroids and physiotherapy with which she had near complete recovery.
A 16-year-old Korean boy presented with acute onset vertigo, dysphagia and gait ataxia of 16 hours duration. He had history of headache and neck pain along with transient vertigo during a water slide ride 12 days before presentation. CT brain showed left cerebellar and left lateral medullary infarcts. CT angiography showed left vertebral dissection with occlusion of left posterior inferior cerebellar artery. A 52-year-old Indian man, presented with acute onset global aphasia and right hemiparesis within 3 hours of onset of symptoms. He received intravenous tissue plasminogen activator (tPA) with partial improvement in his symptoms. He had headache and neck pain since 2 weeks, ever since he had a water slide ride. CT brain was normal, while the CT angiogram showed left carotid dissection. Cervical artery dissection has been reported with roller coaster rides and rarely with delayed presentations. Delayed presentation of cervical artery dissection after water rides have not been reported.
We report the case of a 30-year-old woman, without any previous comorbidities presenting with acute onset headache, altered sensorium and unsteadiness of gait. Neurological evaluation revealed a drowsy patient with papilloedema, bilateral lateral rectus palsy, generalised hyper-reflexia and up going plantar responses. Urgent imaging performed showed extensive cortical venous sinus thrombosis. Workup for secondary causes of cortical venous sinus thrombosis revealed very high titres of antinuclear antibody and anti-dsDNA, but negative antiphospholipid antibodies (APLA). In hospital she started developing other complications of systemic lupus erythematosus (SLE). Urine evaluation revealed proteinuria and granular casts suggestive of glomerulonephritis. Cardiac evaluation revealed moderate pericardial effusion. We have discussed neurolupus as initial presentation of SLE and the rare occurrence of major neurovascular complications without secondary APLA syndrome.
Background and Purpose Cerebral venous thrombosis (CVT), also known as cerebral dural venous thrombosis, is not a very common cause of stroke. It has a diverse clinical presentation, with multiple predisposing factors and imaging findings. The incidence of CVT varies in different studies. We hypothesized that the incidence of CVT in Dubai is more than that reported in the West owing to dehydration caused by the high atmospheric temperature. Methods We retrospectively reviewed the medical records of all patients aged more than 13 years with appropriate International Classification of Diseases, 9th Revision, codes for the diagnosis of CVT from January 1, 2010 to December 31, 2018 from three major hospitals with an acute stroke service in Dubai, United Arab Emirates. Results We identified 138 patients who presented with CVT. The average frequency of CVT was 6.6 per 100,000 population. Fifty percent of the patients presented between May and September, which are considered the hottest months in the UAE. Headache was the most common presentation, followed by seizures. The most important risk factors were the use of oral contraceptive pills, anemia, and polycythemia. Our study showed a higher incidence of anemia, polycythemia, thrombophilia, and abnormal CT brain findings. Conclusion In our study, CVT was more common during the months of summer. Anemia and polycythemia were strongly associated with CVT. Public awareness about CVT, its higher incidence during summer months and strategies to avoid dehydration might be considered to reduce the incidence of CVT in summer months. However, larger studies are needed to confirm definite associations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
