ABSTRACT

OBJECTIVE: We investigated whether the COVID-19 pandemic has affected the clinical characteristics of patients with functional seizure (FS) (at the time of diagnosis) in a large multicenter international study. METHODS: This was a retrospective study. We investigated all patients with FS, who were admitted at the epilepsy monitoring units at six centers in the world: 1. Shiraz, Iran; 2. Salzburg, Austria; 3. Nancy, France; 4. Atlanta, USA; 5. Kuwait City, Kuwait; and 6. Cairo, Egypt. Patients were studied during two time periods: admitted in 2018-2019 (pre-COVID era) and 2020-2021 (COVID era). RESULTS: Three hundred and twenty-six patients were studied. Two hundred and twenty-four (68.7%) patients were diagnosed before and 102 (31.3%) persons during the COVID-19 pandemic. Only, a history of family dysfunction was significantly associated with the COVID-19 pandemic era (Odds Ratio: 1.925, 95% Confidence Interval: 1.099-3.371; p = 0.022). A low level of education might also be associated with FS during the COVID-19 pandemic, at least in some cultures (e.g., the Middle-East). CONCLUSION: The COVID-19 pandemic has not affected the clinical characteristics of patients with FS (at the time of diagnosis). However, a history of family dysfunction was significantly more frequently associated with FS during the COVID-19 pandemic. Multiagency integration of law enforcement responses, social services, and social awareness is recommended to address family dysfunction and domestic violence and support the victims during this pandemic.

ABSTRACT

BACKGROUND: Hemodialysis patients with COVID-19 have been reported to be at higher risk for death than the general population. Several prognostic factors have been identified in the studies from Asian, European or American countries. This is the first national Lebanese study assessing the factors associated with SARS-CoV-2 mortality in hemodialysis patients. METHODS: This is an observational study that included all chronic hemodialysis patients in Lebanon who were tested positive for SARS-CoV-2 from 31st March to 1st November 2020. Data on demographics, comorbidities, admission to hospital and outcome were collected retrospectively from the patients' medical records. A binary logistic regression analysis was performed to assess risk factors for mortality. RESULTS: A total of 231 patients were included. Mean age was 61.46 ± 13.99 years with a sex ratio of 128 males to 103 females. Around half of the patients were diabetics, 79.2% presented with fever. A total of 115 patients were admitted to the hospital, 59% of them within the first day of diagnosis. Hypoxia was the major reason for hospitalization. Death rate was 23.8% after a median duration of 6 (IQR, 2 to 10) days. Adjusted regression analysis showed a higher risk for death among older patients (odds ratio = 1.038; 95% confidence interval: 1.013, 1.065), patients with heart failure (odds ratio = 4.42; 95% confidence interval: 2.06, 9.49), coronary artery disease (odds ratio = 3.27; 95% confidence interval: 1.69, 6.30), multimorbidities (odds ratio = 1.593; 95% confidence interval: 1.247, 2.036), fever (odds ratio = 6.66; 95% confidence interval: 1.94, 27.81), CRP above 100 mg/L (odds ratio = 4.76; 95% confidence interval: 1.48, 15.30), and pneumonia (odds ratio = 19.18; 95% confidence interval: 6.47, 56.83). CONCLUSIONS: This national study identified older age, coronary artery disease, heart failure, multimorbidities, fever and pneumonia as risk factors for death in patients with COVID-19 on chronic hemodialysis. The death rate was comparable to other countries and estimated at 23.8%.

ABSTRACT

BACKGROUND: Levetiracetam is a broad spectrum antiepileptic drug (AED) with proven efficacy when used as adjunctive therapy against myoclonic seizures. We report two patients suffering from epilepsy with myoclonic-astatic epilepsy (MAE) who experienced a paradoxical worsening of seizures after initiation of treatment with LEV, a finding not previously described. CASE PRESENTATION: Patients included were enrolled in an ongoing large prospective study evaluating children and adults with new onset epilepsy in Lebanon conducted at the American University of Beirut Medical Center in association with the Lebanese Chapter of the International League against Epilepsy. Based on an extensive evaluation, these patients were stratified into idiopathic partial, idiopathic generalized, symptomatic partial or symptomatic generalized epilepsies. Whenever possible the electroclinical syndrome was identified according to the ILAE classification of epilepsy syndromes. Patients were subsequently followed up on regular intervals and were assessed for adverse events, and seizure recurrence. MAE was diagnosed in five (1.6%) out of 307 consecutive children enrolled in this study. LEV was used as adjunctive therapy in four of those children with two experiencing a substantial and dose related worsening in the frequency of their myoclonic and atonic seizures. CONCLUSION: LEV should be used with caution in children with MAE and an exacerbation of seizure frequency temporally related to the introduction of LEV should alert the clinician to the possibility of a paradoxical seizure exacerbation.

ABSTRACT

Rhythmic midtemporal discharge (RMTD) is one of the benign epileptiform variants, typically consisting of runs of 4-Hz to 7-Hz activity, lasting up to 10 seconds and maximal over the midtemporal area. We report a child who, during an admission for diagnostic closed-circuit television (CCTV) and electroencephalographic (EEG) monitoring, was found to have prolonged rhythmic monomorphic discharges, alternating over both midtemporal areas, with one of the discharges lasting up to 82 minutes. An analysis of the dominant frequency, during the longest discharge, showed that it was monomorphic throughout. On the basis of various features of these discharges, we concluded that they represented RMTD of unusual duration.

ABSTRACT

PURPOSE: Troponins are very sensitive biomarkers of myocardial injury. Conflicting data regarding elevation of troponin levels following a generalized tonic-clonic (GTC) seizure have been reported. In this study we hypothesized that troponin elevation after a GTC seizure occurs more frequently in patients with cardiovascular risk factors. METHODS: Patients who presented to the ER after a single GTC seizure with troponin levels assessed by cardiac troponin T (cTnT) and drawn within 12h of the GTC seizure were included. Patients with cardiac symptoms, elevated CPK levels or renal insufficiency were excluded. The frequency and risk factors for elevated cTnT levels were analyzed. RESULTS: Fourteen patients with a mean age of 54 years (range: 19-87 years) were included. Four patients (28.6%) had elevated cTnT levels (mean=0.06µg/L; range: 0.035-0.076µg/L). Patients with elevated cTnT levels were significantly older than those with normal levels (77.5 years vs. 45.5 years; P=0.03). Of the eight patients 60 years of age and older, four (50%) had elevated cTnT levels. The coronary heart disease (CHD) score was significantly higher in patients with elevated cTnT levels compared to those with normal levels (13.5 vs. 9.75, P=0.012). CONCLUSIONS: Elevated troponin levels can occur after a GTC seizure. Patients at risk are the elderly and those with cardiovascular risk factors. Our results suggest that elevation of troponin levels after a GTC seizure reflects a minor ischemic cardiac injury related to the demand ischemia during the sympathetic overactivity that accompanies a GTC seizure.

ABSTRACT

BACKGROUND: Extracranial venous stenosis (EVS) has recently been implicated as the primary cause of multiple sclerosis (MS). OBJECTIVE: The aim of this study was to determine the presence of EVS in MS patients. METHODS: We performed selective extracranial venography on 42 patients with early MS (EMS): clinically isolated syndrome (CIS) or relapsing-remitting MS (RRMS) of less than 5 years duration, and late MS (LMS): RRMS of more than 10 years duration. Magnetic resonance imaging (MRI) and clinical relapse data were reviewed for all patients with EVS. RESULTS: EVS was present in 7/29 patients with EMS and 12/13 patients with LMS, a highly significant statistical difference (p< 0.001). Only 3/42 patients (all in the LMS group) had two vessel stenoses, while the rest had only one vessel involved. EVS was seen in 1/11 patients with CIS compared with 6/18 RRMS patients of less than 5 years duration. Disease duration was greater in patients with EVS overall (p < 0.005). LMS remained an independent predictor of EVS following multivariate adjustment for gender, age at disease onset and Expanded Disability Status Scale (EDSS) (Adjusted Odds Ratio = 29 (3-298); p = 0.005]. Within the EMS group, patients with (n = 7) and without (n = 22) EVS had similar EDSS and disease duration, suggesting similar disease severity. No clear correlation could be found between site of EVS and anatomic localization of either clinical relapses or MRI gadolinium-enhancing lesions. CONCLUSIONS: We conclude that EVS is an unlikely cause of MS since it is not present in most patients early in the disease and rarely involves more than one extracranial vein. It is likely to be a late secondary phenomenon.

ABSTRACT

BACKGROUND: A 65-year-old woman presented with decreased oral intake, a reduced level of consciousness, hypercalcemia and hypernatremia. She had previously received lithium for 20 years for a schizoaffective disorder, but this treatment had been discontinued 3 years before presentation. INVESTIGATIONS: Physical examination, laboratory studies including measurement of serum calcium and parathyroid hormone levels, measurement of urine and serum osmolalities before and after desmopressin administration, blood and urine cultures, and a CT scan of the abdomen. DIAGNOSIS: Urosepsis, dehydration, kidney stone disease, hyperparathyroidism, and nephrogenic diabetes insipidus. MANAGEMENT: Hydration, antibiotics, intravenous pamidronate for rapid control of hypercalcemia, parathyroidectomy, surgical removal of the large kidney stones, a low-protein and low-sodium diet, and initiation of treatment with a thiazide diuretic.

ABSTRACT

PURPOSE OF REVIEW: The global prevalence of chronic kidney disease is increasing, as are its complications. Central to the diagnosis, evaluation and management of chronic kidney disease is the estimation of glomerular filtration rate. This article summarizes the various equations used to estimate filtration function and the performance of each in clinical practice. RECENT FINDINGS: During the past year the prediction equations to estimate glomerular filtration rate, especially the Modification of Diet in Renal Disease Study equation, continued to receive much interest. Many studies have compared the performance of the Modification of Diet in Renal Disease Study equation and the Cockcroft-Gault equation. The performance of these equations in various patient populations, such as patients with advanced heart failure, diabetic patients, renal transplantation patients, and the healthy general population, has been extensively studied. Overall, the Modification of Diet in Renal Disease Study equation has had an acceptable validity and has outperformed the Cockcroft-Gault equation in the various populations, but with some limitations that the physician should account for in clinical practice. SUMMARY: The use of the prediction equations to estimate glomerular filtration rate, especially the Modification of Diet in Renal Disease Study equation, should be implemented more frequently in clinical practice. An ever increasing number of studies has validated its use in different patient populations.
