Characteristics and outcome in an Egyptian Cohort with status epilepticus.

OBJECTIVES: Status epilepticus (SE) is an important cause of mortality worldwide. Information regarding associations of mortality outcome in Egypt is limited. The main objective of this study was to describe the clinical characteristics and factors associated with mortality of patients with SE admitted to Cairo University Hospitals. METHODS: A prospective observational hospital-based study was conducted from January 2017 to June 2018. Patients with SE aged ≥12 years old were followed with documentation of outcome on discharge as survival versus death. RESULTS: The study cohort included 144 SE patients. The majority of episodes (96.5%) were with prominent motor features, while nonconvulsive SE occurred in 3.5%. There was a clear semiology evolution in 22.9% of episodes, 56.3% had unchanging semiology (e.g., just convulsive or just nonconvulsive) and the semiology evolution could not be discerned in 20.8%. In relation to treatment, the majority of cases were responsive (46.5%), whereas 43.1% were refractory and only 10.4% were super-refractory SE. Apart from seven patients who were referred to other hospitals, 99 patients survived whereas 38 (26.4%) died. After regression analysis, only absence of a history of epilepsy, semiology evolution and mechanical ventilator use were associated with mortality increasing its odds by 3.7, 5, 111 times, respectively. CONCLUSION: Absence of a history of epilepsy, SE semiology evolution, and mechanical ventilator use was found to be associated with mortality outcome among Egyptian patients with SE.

Relation between the severity of liver cirrhosis and neurological symptoms, nerve conduction study results, and motor unit number estimation.

Liver cirrhosis is a global health problem that can be associated with several neurological manifestations. We aimed to assessment of the relation between the severity of the liver cirrhosis and the neurological symptoms, nerve conduction studies (NCS), as well as detecting subclinical neuropathic affection using motor unit number estimation (MUNE) technique. This cross-sectional study was conducted on 56 cirrhotic patients and 61 age- and sex-matched healthy controls. Neurological manifestations, Child-Pugh classification, Model for End-Stage Liver Disease score, NCS and MUNE using a modified spike-triggered averaging technique were studied. Forty-five (80.3%) of the cirrhotic patients had neurological manifestations. Muscle cramps were the most frequently reported manifestation, followed by fatigue and then numbness. NCS abnormality was significantly related to the presence of neurological symptoms (p < 0.001) and not only to peripheral numbness. Only fatigue was significantly related to the lower MUNE values (p < 0.017). Child-Pugh classification progression was significantly related to the presence of fatigue and abnormal NCS results (p < 0.001); no similar relation was detected between the Child-Pugh classification and the MUNE value (p = 0.103). Higher MELD scores were significantly related to NCS abnormalities (p = 0.014) and negatively correlated, although not significantly, with the MUNE values (r = -0.246 and p = 0.067). The progression of liver cirrhosis was related to the presence of neurological manifestations and nerve conduction abnormalities. Nerve conduction abnormalities may be present even in the absence of clinical numbness. A decline in motor unit number could explain the pathophysiology of fatigue in cirrhotic patients.

Impact of Somatosensory Training on Neural and Functional Recovery of Lower Extremity in Patients with Chronic Stroke: A Single Blind Controlled Randomized Trial.

Recovery of lower extremity (LE) function in chronic stroke patients is considered a barrier to community reintegration. An adequate training program is required to improve neural and functional performance of the affected LE in chronic stroke patients. The current study aimed to evaluate the effect of somatosensory rehabilitation on neural and functional recovery of LE in stroke patients. Thirty male and female patients were recruited and randomized to equal groups: control group (GI) and intervention group (GII). All patients were matched for age, duration of stroke, and degree of motor impairment of the affected LE. Both groups received standard program of physical therapy in addition to somatosensory rehabilitation for GII. The duration of treatment for both groups was eight consecutive weeks. Outcome measures used were Functional Independent Measure (FIM) and Quantitative Electroencephalography (QEEG), obtained pre- and post-treatment. A significant improvement was found in the FIM scores of the intervention group (GII), as compared to the control group (GI) (p < 0.001). Additionally, QEEG scores improved within the intervention group post-treatment. QEEG scores did not improve within the control group post-treatment, except for "Cz-AR", compared to pretreatment, with no significant difference between groups. Adding somatosensory training to standard physical therapy program results in better improvement of neuromuscular control of LE function in chronic stroke patients.

External validation of STESS and EMSE as outcome prediction scores in an Egyptian cohort with status epilepticus.

PURPOSE: There is a lack of data concerning the performance of the outcome prediction scores in patients with status epilepticus (SE) in developing countries. The aim of this study was to compare the predictive performances of the status epilepticus severity score (STESS) and the epidemiology-based mortality score in status epilepticus (EMSE) and adaptation of such scoring system to be compatible with the nature of society. METHOD: This is a prospective study, conducted in Egypt from the period of January 2017 to June 2018. The main outcome measure was survival versus death, on hospital discharge. The cutoff point with the best sensitivity and specificity to predict mortality was determined through a receiver operating characteristic (ROC) curve. RESULTS: Among the 144 patients with SE with a mean age of 39.3 ±â€¯19.5 years recruited into the study, 38 patients (26.3%) died in the hospital with the survival of 99 patients while 7 patients (4.9%) were referred to other centers with an unknown outcome. Although EMSE had a bit larger area under the curve (AUC) (0.846) than STESS-3 (AUC 0.824), STESS-3 had the best performance as in-hospital death prediction score as it has a higher negative predictive value (94.6%) than that of EMSE (90.9%) in order not to miss high-risk patients. CONCLUSION: In the Egyptian population, STESS and EMSE are useful tools in predicting mortality outcome of SE. The STESS performed significantly better than EMSEE combinations as a mortality prediction score.

Neurophysiologic tests screening cognitive impairment in idiopathic intracranial hypertension patients.

BACKGROUND: Idiopathic intracranial hypertension (IIH) is a disorder with increased intracranial pressure of obscure cause. Patients with IIH may suffer from difficulty in thinking or concentrating. This work aimed at highlighting the neurophysiologic suggestions of cognitive impairment in IIH patients. METHODS: Twenty patients with IIH-and a similar number of matched control subjects-were examined in this case-control study. The P300 and contingent negative variation (CNV) were performed. Results from both groups were compared. RESULTS: There were significant lower means of P300 amplitude and CNV amplitude (early and late response) in patients than in controls. Also, there were significant delayed latencies of P300 and CNV in patients than in normal control subjects. Finally, P300 latency was correlated to mini-mental state examination. CONCLUSIONS: We concluded that cognitive affection in IIH is well appreciated at neurophysiologic levels and is related to clinical inputs. We are providing a suggestion of the significant relation between clinical screening (i.e., mini-mental state examination) and NP screening (i.e., P300) of cognitive functions.

Focal interictal epileptiform discharges in idiopathic generalized epilepsy.

Are idiopathic generalized epilepsies (IGEs) truly generalized? Do IGEs represent a continuum or rather distinct syndromes? Focal changes in the electroencephalography (EEG) have been reported in IGEs. The aim of this work is to investigate focal interictal epileptiform discharges (IEDs) in IGEs, and their relation to clinical variables. Forty-one IGE patients (classified according to ILAE, 2001) were recruited from a tertiary center (age 23 ± 10.938 years). Their files were reviewed and they were subjected to clinical examination and interictal EEG. Patients with focal IEDs were compared to those without focal IEDs. Nine patients had juvenile myoclonic epilepsy (JME) and 32 had idiopathic epilepsy with generalized tonic-clonic seizures only (EGTCSA). Focal IEDs were found in 20 patients, mostly in the frontal (45.5 %) and temporal (31.8 %) distribution. Patients with focal IEDs were treated with a larger number of combined antiepileptic drugs (AEDs) (p value = 0.022). No significant difference was found between the two groups regarding age, sex, age at onset, epilepsy syndrome, seizure frequency, family history, AEDs used (sodium valproate and carbamazepine) and their doses. Seventeen EGTCSA patients had focal IEDs. They were treated with larger number of combined AEDs (p value = 0.0142). No significant difference was found between the EGTCSA patients with and those without focal IEDs regarding age, sex, age at onset, seizure frequency, family history and AEDs doses. Caution must be applied in the interpretation of interictal focal IEDs. These focal changes may be related to prognosis, however this needs further investigation.
