RESUMO

The aim of the study is to conduct an overview of systematic reviews (SRs) to provide a contemporary review of the evidence for delivery of Traditional Chinese Patent Medicine (TCPMs) for patients with acute ischemic stroke.SRs were assessed for quality using the Assessment of Multiple Systematic Reviews (AMSTAR) tool and the Oxman-Guyatt Overview Quality Assessment Questionnaire (OQAQ). We assessed the quality of the evidence of high methodological quality (an AMSTAR score ≥9 or an OQAQ score ≥7) for reported outcomes using the GRADE (the Grading of Recommendations Assessment, Development and Evaluation) approach.(1) Dan Shen agents: tiny trends toward the improvement in different neurological outcomes (RR = 1.16, 1.10, 1.23, 1.08, 1.12); (2) Mailuoning: a tiny trend toward improvement in the neurological outcome (RR = 1.18); (3) Ginkgo biloba: tiny trends toward improvement in the neurological outcome (RR = 1.18, MD = 0.81); (4) Dengzhanhua: a tiny trend toward an improvement in neurological (RR = 1.23); (5) Acanthopanax: a small positive (RR = 1.17, 1.31) result on neurological improvement reported; (6) Chuanxiong-type preparations: neurological functional improved (MD = 2.90);(7) Puerarin: no better effect on the rate of death or disability (OR = 0.81, 95% CI 0.35-1.87); (8) Milk vetch: no better effect on the rate of death (OR = 0.66, 95% CI: 0.11-2.83);(9) Qingkailing: rate of death reduced (OR = 0.66, 95% CI: 0.11-2.83). Limitations in the methodological quality of the RCTs, inconsistency and imprecision led to downgrading of the quality of the evidence, which varied by review and by outcome. Consequently, there are currently only weak evidences to support those TCPMs.The 9 TCPMs may be effective in the treatment of acute ischemic stroke, as the GRADE approach indicated a weak recommendation for those TCPMs' usage.

RESUMO

α-Amino adipic semialdehyde (α-AASA) accumulates in body fluids from patients with pyridoxine-dependent epilepsy because of mutations in antiquitin (ALDH7A1) and serves as the biomarker for this condition. We have recently found that the urinary excretion of α-AASA was also increased in molybdenum cofactor and sulfite oxidase deficiencies. The seizures in pyridoxine-dependent epilepsy are caused by lowered cerebral levels of pyridoxal-5-phosphate (PLP), the bioactive form of pyridoxine (vitamin B(6)), which can be corrected by the supplementation of pyridoxine. The nonenzymatic trapping of PLP by the cyclic form of α-AASA is causative for the lowered cerebral PLP levels. We describe 2 siblings with clinically evident pyridoxine-responsive seizures associated with increased urinary excretion of α-AASA. Subsequent metabolic investigations revealed several metabolic abnormities, all indicative for molybdenum cofactor deficiency. Molecular investigations indeed revealed a known homozygous mutation in the MOCS2 gene. Based upon the clinically evident pyridoxine-responsive seizures in these 2 siblings, we recommend considering pyridoxine supplementation to patients affected with molybdenum cofactor or sulfite oxidase deficiencies.

RESUMO

We report about a patient (66 years) who was referred to our psychiatric hospital because of a progressive confusional state with acute onset. The colleagues of the referring psychiatric hospital considered a first manic episode as the cause of the symptoms and under therapy with haloperidol the confusional state had shown a progression.The clinical examination's findings were a mild central facial paresis on the right side and a mild hemiparesis on the right side with elevated reflex levels.The patient was disoriented, he had cognitive and mnestic deficits. His reasoning was slowed, incoherent and perseverating. The patient had a slight euphoria.An EEG recording showed a continuous regional EEG-seizure pattern. In combination with the clinical symptoms we diagnosed a nonconvulsive status epilepticus. Under anticonvulsive treatment with Lorazepam and Valproic acid the status epilepticus sustended but a control EEG recording showed signs of a Valproate-encephalopathy. Under treatment with Topiramate symptoms ameliorated but due to a vascular dementia the patient still showed fluctuating symptoms of cognitive and mnestic disturbances.

RESUMO

UNLABELLED: In previous years, several publications have reported cases of infants presenting neurological and gastrointestinal symptoms after ingestion of star anise tea. Such teas are sometimes given in various cultures for the treatment of infant colic pains. In most cases, the cause of intoxication was contamination of Chinese star anise (Illicium verum) by Japanese star anise (Illicium anisatum). Indeed, the toxicity of Illicium anisatum, also known as Shikimi, is caused by its content in potent neurotoxins (anisatin, neoanisatin, and pseudoanisatin), due to their activity as non-competitive antagonists of GABA receptors. The main reasons explaining the frequent contaminations are the strong macroscopic resemblance of the 2 substances, as well as the fact that the fruits are often sold partially broken or in ground form. Therefore, in most cases, chemical analysis is required to determine the possible adulterations. CASE REPORT: A 2-month-old infant, in good general health, was brought to the emergency unit after 3 consecutive episodes of central cyanosis and tetany of the limbs with spontaneous recovery the same afternoon. The child was also very irritable, regurgitated a lot, and positioned himself in opisthotonos. Between these episodes, the neurological exam showed some perturbations (horizontal nystagmus and Bell's phenomenon, hypertony of the extensor muscles, and mild hypotony of the axial flexor muscles) with slow improvement over the following hours. The remaining clinical exam, the laboratory work (complete blood count, renal, hepatic, and muscular tests, capillary blood gas, plasmatic amino acids, and urinary organic acids), and the electroencephalogram findings were all normal. In the course of a detailed interview, the parents reported having given 3 bottles to their child, each one containing 200 mL of an infusion with 4 to 5 fruits of star anise, in the hours preceding the symptoms to relieve colic pains. The last seizure-like event took place approximately 8h after the last ingestion. We could prove the ingestion of anisatin, the toxic substance found in Japanese star anise, and the contamination of Chinese star anise by the Japanese species. Indeed, the anisatin analysis by liquid chromatography and mass spectroscopy (LC-MS) in a urine sample taken 22 h after the last infusion ingestion showed trace amounts of the substance. In another urine sample taken 33 h after ingestion, no anisatin could be detected. Furthermore, the analysis of the fruit sample gave an anisatin concentration of 7800 µg/kg while the maximum tolerance value in Switzerland is 1000 µg/kg. CONCLUSION: The evaluation of ALTE in infants should always include the possibility of intoxication. Star anise is generally considered a harmless medicine. Nevertheless, it can sometimes cause a severe intoxication resulting in various neurological and gastrointestinal symptoms. To prevent such events, not only the parents, but also the care personnel and pharmacists must be informed about the possible adverse effects caused either by the overdose of Chinese star anise or by the eventual contamination of herbal teas with Japanese star anise. A better control of the substances by the health authorities is also necessary.

RESUMO

BACKGROUND: Hereditary aceruloplasminaemia is a disorder of iron metabolism that is characterised by iron accumulation in the brain and other visceral organs. In previously reported cases, individuals with the disorder were noted to have evidence of iron accumulation in the brain. Oral chelating agents have not been used in neurological diseases of iron metabolism. METHODS: A 54-year-old woman who presented with ataxia, lower extremity spasticity and chorea was evaluated for evidence of the source of neurological dysfunction. RESULTS: Blood studies revealed no detectable ceruloplasmin. Marked iron overload was defined by a liver biopsy, which showed a variegated pattern consistent with a primary cause of iron overload. Review of MRI scans showed progressive brain atrophy without visible iron accumulation occurring over a 5-year period. The history suggested that neurodegeneration was coincident with aggressive oral iron replacement. Oral chelation improved many symptoms. CONCLUSIONS: Our findings in this patient suggest that disorders of iron transport such as aceruloplasminaemia can be a cause of neurological symptoms such as chorea and cognitive decline, as well as progressive neurodegeneration in the absence of visible iron on MRI scans. We found that oral iron chelation was effective at improving symptoms.

RESUMO

We report the first known case of anorexia nervosa (AN) with Marchiafava-Bignami Disease (MBD) that responded to high-dose intravenous corticosteroid administration. A 16-year-old Japanese female with AN was diagnosed with MBD after rapid weight loss. During the acute stage, she suffered from a sudden onset of coma. After regaining consciousness, she presented with lack of movement, apathy, labile affect, and poverty of speech. On admission, magnetic resonance imaging showed an area of demyelination in the splenium of the corpus callosum. Positron emission tomography obtained 7 days after admission showed areas of hypoperfusion in the medial temporal lobe and in regions anterior and posterior to the central sulcus.

RESUMO

CASE REPORT: A 45-year-old patient with cervix carcinoma received combined radiochemotherapy including cisplatin. After a cumulative dose of 240 mg/m(2) the patient suddenly became somnolent and developed a severe tetraparesis and generalized seizures. After ruling out intracranial bleeding, cerebral metastases as well as infectious and metabolic causes of this condition, a severe toxic encephalopathy was diagnosed based on the clinical findings and MRI scans. After symptomatic treatment on the intensive care unit all symptoms were completely reversible. CONCLUSION: Toxic encephalopathy is a rare but dramatic complication of various cytostatic drugs. With the widespread use of cisplatin this rare disorder should be kept in mind.

RESUMO

The purpose of the present study was to evaluate the clinical effectiveness of kamishoyosan for antipsychotic-induced tardive dyskinesia, and to investigate the relationship between tardive dyskinesia and serum brain-derived neurotrophic factor (BDNF) levels. Sixty-nine schizophrenia patients were enrolled; of these, 49 presented with tardive dyskinesia while the remaining 20 patients showed no tardive dyskinesia. The tardive dyskinesia group was treated for 16 weeks with kamishoyosan and assessed using the abnormal involuntary movement scale. The abnormal involuntary movement scale scores in the tardive dyskinesia group were evaluated at baseline and after 4, 8, and 16 weeks of treatment. The BDNF levels of all subjects were measured at baseline in order to compare differences in serum BDNF levels between the tardive dyskinesia group and the non-tardive dyskinesia group, and to correlate the severity of tardive dyskinesia and serum BDNF in the tardive dyskinesia group. A meaningful reduction in total abnormal involuntary movement scale scores was observed in the tardive dyskinesia group treated with kamishoyosan at 4, 8, and 16 weeks of treatment (P < 0.01). No significant differences in serum BDNF levels were detected between the tardive dyskinesia group and the non-tardive dyskinesia group at baseline. Furthermore, no significant correlation was seen between the severity of tardive dyskinesia and serum BDNF levels. The present study suggests that kamishoyosan might be a promising adjunctive treatment for antipsychotic-induced tardive dyskinesia.

RESUMO

The neuropsychological and clinical histories of three male siblings affected by pyridoxine-dependent seizures with known homozygous antiquitin mutations are presented. Neuropsychological evaluation is reported from when the siblings were 11, 9, and 7 years of age. Two of the siblings had received early pyridoxine treatment (antenatal, 2-4 wks into pregnancy) and one had received late treatment (2mo postnatal). However, there was no differential effect on cognitive outcome, with all three siblings having moderate to severe learning disability. Unlike previously reported cases that received early postnatal treatment, none of the siblings had relatively preserved non-verbal cognitive skills. Equally, their intellectual performance over time did not increase above the 1st centile despite high maintenance doses of vitamin B6 (range 16-26 mg/kg/d), and mild sensory neuropathy was reported on nerve conduction studies. The findings in these siblings challenge assumptions that early and high dose pyridoxine treatment can benefit cognition in this population and suggest routine electromyography monitoring may be beneficial.

RESUMO

"Atypical anti-psychotics" are substances of choice in treating drug-induced psychosis (DP) in Parkinson's disease (PD). We report on four patients with DP who received treatment with ziprasidone after previously applied clozapine and quetiapine had failed. Three patients showed a significant improvement of DP, without deterioration of motor function. In one case, ziprasidone considerably increased decline in off-periods. Two patients developed pathological laughing as a possible side-effect of ziprasidone. Ziprasidone may serve as an additional "atypical anti-psychotic" for the treatment of DP in PD but can also induce deterioration of motor function.

RESUMO

In vivo magnetic resonance techniques such as magnetic resonance imaging (MRI) and magnetic resonance spectroscopy have been some of the most useful tools for evaluation of neurologic diseases. In subacute sclerosing panencephalitis, magnetic resonance spectroscopy can be an additional tool for evaluation of disease progression or the efficacy of the treatment, such as interferon or inosiplex, compared with MRI. Inosiplex is one of the effective drugs for subacute sclerosing panencephalitis, but our in vivo and in vitro magnetic resonance spectroscopic study indicated that inosiplex affects the spectra, suggesting a possible failure of neurologic evaluation in a patient with subacute sclerosing panencephalitis treated with inosiplex.

RESUMO

BACKGROUND: Dyskinesias are a transient but severe complication of subthalamotomy in some patients. PATIENTS AND METHODS: Three patients with Parkinson's disease undergoing bilateral micro-recording guided surgery of the subthalamic nucleus (STN) are described; deep brain stimulation (DBS) was used in one case, and subthalamotomy in the other two. Prior to surgery, levodopa induced dyskinesia had improved (< or = 50%) under treatment with amantadine (400 mg/day, po) in all three patients. The patient treated with DBS developed severe dyskinesia a few days after discharge and began self medication with amantadine but showed no improvement. This suggested a possible lack of response to amantadine for treatment of dyskinesias induced by surgery of the STN. RESULTS: Both patients treated with bilateral subthalamotomy developed unilateral choreoballistic movements immediately after surgery, despite not taking levodopa (L-dopa). Patients were scored using the dyskinesia scale and started treatment with 400 mg amantadine (po) for 4 days within the first postoperative week with no effect on dyskinesia score or its phenomenology. Amantadine was therefore discontinued. One month after surgery both patients were free of involuntary movements with an improvement of about 60% in the "off" state UPDRS motor score. Six month follow up showed maintained antiparkinsonian benefit, without need for levodopa treatment and complete absence of dyskinesia. CONCLUSION: The present findings suggest that: (i) amantadine probably exerts its anti-dyskinetic effect by acting on the "indirect" pathway; (ii) the pathophysiological mechanisms of subthalamotomy induced dyskinesias may differ from those involved in L-dopa induced dyskinesias; (iii) dyskinesias induced by STN surgery resolve spontaneously as compensatory mechanisms develop.

RESUMO

OBJECT: Convection-enhanced delivery (CED) is a novel method for delivering therapeutic agents to infiltrative brain tumor cells. For agents administered by CED, changes on magnetic resonance (MR) imaging directly resulting from catheter placement, infusion, and the therapeutic compound may confound any interpretation of tumor progression. As part of an ongoing multiinstitutional Phase I study, 14 patients with recurrent malignant glioma underwent CED of interleukin (IL) 13-PE38QQR, a recombinant cytotoxin consisting of human IL-13 conjugated with a truncated Pseudomonas exotoxin. Serial neuroradiographic changes were assessed in this cohort of patients. METHODS: Patients were treated in two groups: Group 1 patients received IL13-PE38QQR before and after tumor resection; Group 2 patients received infusion only after tumor resection. Preoperative and postinfusion MR images were obtained prospectively at specified regular intervals. Changes were noted along catheter tracks on postresection MR images obtained in all patients. A simple grading system was developed to describe these changes. When MR imaging changes appeared to be related to IL1 3-PE38QQR, patients were followed up without instituting new antitumor therapy. CONCLUSIONS: As CED of therapeutic agents becomes more common, clinicians and investigators must become aware of associated neuroimaging changes that should be incorporated into toxicity assessment. We have developed a simple grading system to facilitate communication about these changes among investigators. Biological imaging modalities that could possibly distinguish these changes from recurrent tumor should be evaluated. In this study the authors demonstrate the challenges in determining efficacy when surrogate end points such as time to tumor progression as defined by new or progressive contrast enhancement on MR imaging are used with this treatment modality.

RESUMO

BACKGROUND: Minocycline, a semi-synthetic tetracycline antibiotic, is an effective neuroprotective agent in animal models of cerebral ischemia when given in high doses intraperitoneally. The aim of this study was to determine if minocycline was effective at reducing infarct size in a Temporary Middle Cerebral Artery Occlusion model (TMCAO) when given at lower intravenous (IV) doses that correspond to human clinical exposure regimens. METHODS: Rats underwent 90 minutes of TMCAO. Minocycline or saline placebo was administered IV starting at 4, 5, or 6 hours post TMCAO. Infarct volume and neurofunctional tests were carried out at 24 hr after TMCAO using 2,3,5-triphenyltetrazolium chloride (TTC) brain staining and Neurological Score evaluation. Pharmacokinetic studies and hemodynamic monitoring were performed on minocycline-treated rats. RESULTS: Minocycline at doses of 3 mg/kg and 10 mg/kg IV was effective at reducing infarct size when administered at 4 hours post TMCAO. At doses of 3 mg/kg, minocycline reduced infarct size by 42% while 10 mg/kg reduced infarct size by 56%. Minocycline at a dose of 10 mg/kg significantly reduced infarct size at 5 hours by 40% and the 3 mg/kg dose significantly reduced infarct size by 34%. With a 6 hour time window there was a non-significant trend in infarct reduction. There was a significant difference in neurological scores favoring minocycline in both the 3 mg/kg and 10 mg/kg doses at 4 hours and at the 10 mg/kg dose at 5 hours. Minocycline did not significantly affect hemodynamic and physiological variables. A 3 mg/kg IV dose of minocycline resulted in serum levels similar to that achieved in humans after a standard 200 mg dose. CONCLUSIONS: The neuroprotective action of minocycline at clinically suitable dosing regimens and at a therapeutic time window of at least 4-5 hours merits consideration of phase I trials in humans in view of developing this drug for treatment of stroke.

RESUMO

Neonatal-type nonketotic hyperglycinemia treatment remains unsatisfactory, even if started early. A review of six patients who underwent treatment for neonatal-type nonketotic hyperglycinemia in our hospital is presented. All patients were treated with a standardized protocol. Medical histories were retrieved from case notes. All six patients had elevated cerebrospinal fluid plasma glycine levels initially. All but one had received sodium benzoate and dextromethorphan from 1 month of age. All suffered from intractable seizures and severe mental retardation, and only two patients remain alive. One patient died at 5 days of age. No resuscitation was attempted in accordance with the family's wish after genetic counseling. The prognosis of neonatal nonketotic hyperglycinemia remains poor with current treatment. Genetic counseling helps parents cope with this devastating genetic disease.

RESUMO

Since antineoplastic activity varies, sensitive methods for individual assessment of efficacy are needed. We demonstrate the clinical value of MR spectroscopy in monitoring chemotherapy in a patient with recurrent glioma after stereotactic radiotherapy. Diagnostic imaging before and after chemotherapy included contrast-enhanced MRI, single-voxel proton MR spectroscopy ((1)H MRS), (1)H MR spectroscopic imaging ((1)H SI), and fluorodeoxyglucose (FDG) positron-emission tomography (PET). A significant decrease in choline signal intensity was observed 2 months after chemotherapy indicating tumour chemosensitivity, in line with tumour shrinkage on MRI and decreased uptake of FDG. Assessment of early response by MRS may help to improve treatment protocols in other patients.
