Sleep quality, daytime sleepiness, and insomnia in patient with epilepsy: A single center experience from Saudi Arabia.

OBJECTIVES: To measure the burden of insomnia and daytime sleepiness (DTS) and their effects on sleep quality, and the risk factors of poor quality of sleep. METHODS: We conducted a cross-sectional study of 218 epilepsy patients. We administered well-validated and previously translated questionnaires to assess sleep quality, insomnia, and DTS using the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale, respectively. RESULTS: Approximately 75% of participants reported poor sleep quality. Moreover, 42.2% did not have insomnia, while 37.6%, 17.9%, and 2.3% had subthreshold insomnia and clinical insomnia of moderate and severe severity, respectively. Roughly 64.2% of participants had normal sleep, 17.8% had an average amount of DTS, and 16.9% and 0.9% may and should seek medical attention, respectively. Compared to normal sleepers, patients with clinical insomnia were 5.45 times likely to experience poor sleep quality, whereas patients with an average amount of DTS and who were recommended to seek medical attention were 6.84 and 44.15 times likely to experience poor sleep quality, respectively. Patients who had seizures every month were 2.51 times likely to experience poor quality sleep, compared to patients who had seizures annually. CONCLUSION: We found a higher prevalence of poor quality of sleep, insomnia, and excessive DTS in our sample of Saudi epilepsy patients.

Electrodiagnostic reference data for sensory nerve conduction studies in Saudi Arabia.

OBJECTIVE: To estimate reference data for the commonly performed sensory nerve conduction studies (NCS) using a cohort of healthy subjects from Saudi Arabia. METHODS: This is a cross-sectional study conducted between May 2015, and June 2019. Sensory nerve action potential (SNAP) amplitude, conduction velocity (CV), and peak latency (PL) were recorded. Associations between these parameters and the covariates (age, sex, height, weight, and body mass index) were tested with Pearson correlations. Reference data were then derived using the lowest percentile that could be reliably determined for SNAP amplitude and CV. Reference data were derived using the highest percentile for PL. RESULTS: Upper and lower limb sensory NCS were performed in 127 and 137 participants, respectively. Age was the only covariate that required adjustment for estimation of SNAP amplitude. Therefore, a prediction model was generated for each nerve. Percentile estimation for PL and CV did not require adjustment for any of the covariates. Hence, it was derived for all the subjects pooled together. CONCLUSION: The sensory NCS reference data were comparable to the data from other countries. However, minimal differences were observed. Further studies are required with a focus on the older age group.

Electrodiagnostic reference data for motor nerve conduction studies in Saudi Arabia.

OBJECTIVE: To determine nerve conduction studies (NCS) reference data for motor nerves and F-waves in the upper and lower limbs of healthy subjects in Saudi Arabia. METHODS: This is a cross-sectional study conducted between May 2015 and June 2019. Healthy subjects without neurological or systemic diseases were recruited. Motor NCS were performed following a standard protocol. Pearson correlations were employed between NCS parameters and age, gender, height, weight, and body mass index. Reference data were generated using the percentile method. RESULTS: A total of 127 subjects were recruited for the upper limb studies and 137 for the lower limb studies. Quantile regression models were generated to estimate compound muscle action potential amplitude (adjusted for age), as well as F-wave minimal latency (adjusted for height). The estimated reference limits of distal motor latency (ms) and conduction velocity (m/s) for the different nerves were, respectively, 3.7 and 50 for the median nerve, 3.3 and 50 for the ulnar nerve, 5.8 and 40 for the tibial nerve, and 5.0 and 40 for the fibular nerve. CONCLUSION: The reference data for motor NCS parameters and F-wave minimal latency are generally comparable with those of Western countries. However, minimal differences were observed. The underrepresentation of the older age group warrants future studies.

Cerebral Venous Thrombosis With Topical Estrogen-Progesterone Use in a Young Heterosexual Male: A Case Report.

INTRODUCTION: Our report sheds light on the risk of topical hormonal use in relation to cerebral venous sinus thrombosis. We diagnosed our patient with cerebral venous thrombosis (CVT) using computed tomography venogram, then detailed history and examination were obtained, and thorough blood tests and imaging were done to exclude other causes of CVT like thrombophilias, infections, and malignancies. CASE REPORT: Our patient is a 37-year-old heterosexual male, presented with headache only. The computed tomography venogram showed extensive CVT in the right internal jugular vein, sigmoid, transverse, and straight cerebral venous; detailed history and investigations suggest that his use of crushed oral contraceptive pills mixed with water topically on the scalp is the most important predisposing factor. This patient was managed with anticoagulants and is being followed in the clinic. CONCLUSION: Oral hormonal use in contraceptives is a known risk factor for CVT. This case sheds light on the importance of topical hormonal use concerning CVT in females and males; it stresses the need for more studies in that area, as it is poorly studied.

Unusual presentation of a giant thoracic spinal cord lipoma.

INTRODUCTION: Non-dysraphic intradural spinal cord lipomas are rare, and true intramedullary cervical-thoracic lipomas are extremely rare. Spinal lipomas usually present with chronic, progressive myelopathic features. Unlike dysraphic lipomas, which are usually located in the lumbo-sacral region, non-dysraphic lipomas are usually located in the cervical or thoracic spine. CASE PRESENTATION: We present an unusual case of a 21-year-old female who presented with four months of severe back pain, progressive spasticity, and weakness in the lower limbs. Magnetic resonance imaging (MRI) revealed a T1- and T2-hyperintense lesion between D4 and D6. DISCUSSION: This fatty intramedullary lesion had undergone evolution and a possible hemorrhagic infarct and cord compression. The patient underwent an urgent dorsal laminoplasty and total resection of this lesion, which histopathology indicated was a fibrous lipoma. Total resection is possible in such cases if a micro-surgical technique that includes neurophysiological monitoring is used.
