BackgroundGuillain-Barre' syndrome (GBS) is a serious autoimmune disorder in which the immune system attacks healthy nerve cells of the peripheral nervous system causing polyradiculoneuropathy which leads to weakness, numbness, and tingling, and can eventually cause paralysis. Autoimmune conditions like GBS can induce a high level of inflammation resulting in an increase in the C-reactive protein( CRP) production. The aim of this study is to assess the relationship between CRP level and the clinical severity as well as the electrophysiological findings of nerve conduction studies in patients with GBS.MethodsTwenty- four patients (10 males &14 females) with ages ranged from 14 to 50 years and a mean age of 33.46 ±12.25 years who fulfilled the clinical criteria for diagnosing GBS were recruited within the first 2 weeks of onset of illness, in a cross- section study. They underwent general and neurological examination. Nerve conduction studies as well as assessment of serum CRP level were done.ResultsThere was a statistically significant positive correlation between clinical severity assessed by (Hughes disability scale) and serum CRP level in GBS patients. Multivariate logistic regression analysis showed that both gastroenteritis, cranio-bulbar affection, need for mechanical ventilation (MV), disability score >4, and absent motor and sensory responses were significantly associated with high serum CRP level >6mg/dl.ConclusionsThe results of this study support the hypothesis that in GBS patients, gastroenteritis, craniobulbar affection, need for MV, disability score >4, and absent motor and sensory nerve responses were significantly related to high serum CRP level. This reflects the negative impact of the inflammatory response elicited by high CRP level on clinical severity in GBS patients, and so it may be used as a prognostic marker of clinical severity of GBS and this can help in therapeutic decision making.

Background Several factors affect acute ischemic stroke (AIS) outcomes. Objective This study aimed to assess the role of the leukocyte count, neutrophil/lymphocyte ratio (NLR), and c reactive protein (CRP) as early predictors of outcome in AIS patients. Methods This study was conducted on 60 AIS patients. They were subjected to detailed history taking, clinical examination, brain imaging, and laboratory assessment including the CRP, white blood cell (WBC) count, absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and NLR which is calculated by dividing ANC by ALC. Neurological scales were used to assess the level of consciousness by the Glasgow Coma Scale (GCS) and stroke severity by the National Institute of Health Stroke Scale (NIHSS) at the first 48 h of stroke onset as well as 1 week and 2 weeks later for the assessment of short-term functional neurological outcome. Results Sixty percent of the patients had unfavorable outcomes assessed by the Modified Rankin Scale (mRS). Patients with unfavorable outcomes had higher NIHSS scores. NLR was positively correlated with WBC count, ANC, and CRP. The higher WBC, NLR, and NIHSS, the unfavorable the outcome was. Conclusion The higher WBC, the NLR, and the level of CRP at the onset of AIS, the more severe stroke and the poorer the short-term outcome are expected.

The first-line management for idiopathic trigeminal neuralgia (ITN) is medical therapy. The effectiveness of medications typically wanes over time,so we need to evaluate other modality of therapy. Objective: To compare pharmacotherapy versus Gamma knife radiotherapy (GKRS) in relief of pain in patients with idiopathic trigeminal neuralgia (ITN). Methods: the study included sixty eight patients with idiopathic trigeminal neuralgia. They were assessed by Barrow Neurological Institute (BNI) pain intensity scale. They were classified into two groups: Group I: 34 patients, were treated by GKRS and were chosen from Gamma knife center in Nasser institute hospital. They were 19(55.9%) male and 15 (44.1%) female with ages ranged from 40-59 years (Mean±SD was 49.5±6.1). They were assessed by BNI scale before and immediately after GKRS, One month and three months after GKRS treatment. Group II: 34 patients, were chosen from neurology department Zagazig University Hospitals. They were 19 (55.9%) male and 15 (44.1%) female with ages ranged from 40-60 years (Mean±SD was 49.0±6.95). They were assessed by BNI scale before and one week after pharmacotherapy, One month and three months after pharmacotherapy. Results: There was no statistically significant difference between the two groups regarding pain intensity before GKRS or pharmacotherapy (p=0.33) while one week after pharmacotherapy ten (29.4%) patients showed statistically significant improvement of pain.After one month, group I showed statistical significant better outcome (41.2%) than group II (8.8%). BNI score three months after managements was highly statisticallly significant better (32.4%) among group I than group II (p=0.001). Most of group I (82.4%) had good overall outcome while 50% of group II had fair outcome and26.5% had good outcome.Conclusion: medical management of ITN had an initial good results in improving pain intensity which begins to wane over one month and the effect of GKRS begins to appear. The effect of GKRS on ITN pain is still evolving through three months follow up.

Platelet activation in cerebrovascular diseases is associated with recurrent stroke and death. Aspirin is an effective antiplatelet agent, exhibiting its action by irreversibly inhibiting platelet cyclooxygenase-1 enzyme, thus preventing the production of thromboxane A 2 (TXA 2 ). Objectives: The study is designed to find the frequency of aspirin resistance (AR) among acute ischemic non-cardioembolic stroke patients, and to assess the clinical picture of those patients. Mehtods: This study included 80 patients39 males and 41 females (mean age: 63 years ± 11.8 SD), they were diagnosed clinically and via brain imaging within 24 hours following stroke onset. They were given non coated, same preparation of aspirin 150 mg/day regularly and under observation, Low molecular weight heparin 40 mg per day. The patients were followed up clinically and via GCS, NIHSS and APACHEII scales. Assessment of aspirin resistance was done one week after regular aspirin intake through: bleeding time, coagulation time and assessment of thromboxaneA2 level in serum using ELIZA. The patients were classified into two groups aspirin resistant (AR) and aspirin sensitive (AS) and the data were compared in both. Results: AR patients represented 33.75% of our sample. History of TIAs and stroke was more prevalent among them. In AR patients: the followings were also more frequent: more affection of consciousness, power, sensation, language, coordination, vertigo, vomiting, large size of cerebral infarcts, temporal and parietal infarcts. There were high significant negative correlation between GCS and TXA2level and between the later and changes in bleeding time in the first day and 7 days following stroke onset. On the other hand there were high positive correlation between TXA2 level and NIHSS score and infarct size. Coclusion: AR was frequent among ischemic non-cardioembolic stroke and they were associated with history of TIAs and previous strokes, and presented with more severe clinical presentation and larger size of cerebral infarcts, So early identification of AR prevents its fruitless use.
