ABSTRACT
Peri-ictal water drinking (PIWD) is a rare vegetative manifestation of temporal lobe epilepsy without a definite lateralisation value. We report a case of PIWD in a 22-year-old Omani male patient with post-concussion syndrome and epilepsy presented to a tertiary care hospital in Muscat, Oman, in 2021 for evaluation of paroxysmal events. His behaviour of PIWD was misinterpreted by his family until characterised in the epilepsy-monitoring unit as a manifestation of epilepsy that was treated medically. To the best of the authors' knowledge, this is the second reported case in the region.

Objectives: Dimethyl fumarate (DMF) is known to cause lymphopenia when used to treat patients with multiple sclerosis (MS). However, research on DMF therapy in the Arab world, especially in Oman, is scarce. This study aimed to analyse the prevalence of lymphopenia among Omani patients with MS and their reasons for discontinuing DMF therapy. Methods: In this retrospective study, the medical records of Omani patients with MS who were treated using DMF at two tertiary hospitals in Muscat, Oman, from February 2017 to February 2023 were reviewed. Their demographic, clinical and laboratory data were retrieved and analysed. Absolute lymphocyte count values at baseline and at the last follow-up, as well as the reasons for discontinuing DMF therapy, were collected. Descriptive and inferential statistical techniques were used for data analysis. Binary-logistic regression analysis was used to identify the risk factors for DMF-induced lymphopenia. Results: A total of 64 Omani patients with MS were included in this study. The majority of the study participants (n = 40; 63%) were female. All included patients started DMF therapy at the mean age of 33 ± 7.7 years. After administration of DMF, 14 (21.9%) patients developed grades 1-3 of lymphopenia. The DMF therapy was discontinued for 23 (36.0%) patients, mainly in response to adverse events or confirmed pregnancy. Female gender was the only significant predictor of DMF-induced lymphopenia (P = 0.037). Conclusions: Most Omani patients with MS had mild lymphopenia (grades 1-2). Early adverse events and pregnancy were the main reasons provided for discontinuing DMF therapy.

Several mimics of acute ischemic stroke may complicate the decision to administer intravenous thrombolysis. Developmental venous anomalies (DVA) are fairly common variants of normal cerebral vasculature and may occasionally present with acute focal neurologic symptoms. We report a case of DVA presenting with the acute onset of focal neurologic deficits and focal hypodensities on the CT of the brain, resulting in a dilemma regarding whether to administer intravenous tissue-type plasminogen activator (IV tPA) for stroke thrombolysis. Recognition of subtle brain changes on the CT that were inconsistent with an acute ischemic stroke led to further imaging and a definitive diagnosis. Developmental venous anomalies should be considered in the differential diagnosis of acute ischemic stroke.
