Peri-ictal Water Drinking in an Omani Patient with Bilateral Mesial Temporal Sclerosis.

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.

Computed-tomography evaluation of parietal foramen topography in adults: a retrospective analysis.

BACKGROUND: The parietal foramen (PF) of the skull is a variable anatomic feature with important implications for venous drainage, infection, and injury. Its topography is clinically relevant for neurosurgeons for intracranial navigation and preoperative planning. METHODS: PF topography was investigated in a series of 440 head computed-tomography scans of Omani subjects at Sultan Qaboos University Hospital. The mean age of the patients was 52 ± 17 years and there were 160 males and 280 females. The topography features of the PF, including frequency, diameter, patency, and relative position in relation to the superior sagittal sinus (SSS), were recorded. Additionally, sex and laterality differences in PF parameters were analyzed using a Chi-square test. RESULTS: The overall prevalence of PF was 72.3% (318/440). The bilateral presence of PF was identified in 34% of skulls. Unilateral right-side prevalence was 18.2%, while left prevalence was 13.2% (p = 0.62). The prevalence of unilateral accessory PF on the right side was 1.8%, while it was 1.1% on the left (p = 0.69). PF within the sagittal suture/or intra-sutural PF was observed in 6.8% of skulls, with a frequency of 9.4% in men and 5.4% in women (p = 0.29). The diameter of the PF was 1.45 ± 0.74 mm on the right side, and 1.54 ± 0.99 mm on the left side (p = 0.96). There were 2% of incomplete PF. The PF was located over the SSS in 70.3% on the right side and 53.8% on the left side. No significant differences were observed between the PF topography parameters and sex or laterality. CONCLUSION: The present study for the first time reports the baseline data of PF topography in a large sample of CT scans in the Arab population. The geography and race influence the PF topography differences. PF may be used as a reliable landmark of SSS. The morphological characteristics and distribution of PF reported in this study have clinical implications for imaging diagnosis, intracranial navigation of vascular disorders, and treatment.

Pediatric traumatic brain injury in a high-income developing country: experience at a level 1 neuro-trauma center.

BACKGROUND: Data on the incidence, prevalence and mortality of pediatric traumatic brain injuries (TBIs) in developing countries are not readily available or do not exist. AIM: The aim of this study was to study the epidemiology of pediatric TBI in developing countries. METHODS: A retrospective study was conducted in a high-volume Neurosurgery Department where we reviewed pediatric cases presenting with TBI between January 2015 and December 2019. Data were collected from the electronic medical records including the patients' demographics, neuro-vital signs, mechanism of TBI and treatment types. Radiological images were screened, and patients were classified according to the type of intracranial hemorrhage. The patient's outcome and Glasgow Coma Scale on discharge were also recorded. RESULT: Nine hundred and eighty-five cases with TBI were admitted over the period of 5 years. The average age was 53.3 months standard deviation (SD) of 39.4. Male gender accounted for 63.7% of the cases. The most common mechanisms of injuries were falls and road traffic accidents/motor vehicle collisions (63.3%, 18.3%), respectively. Nausea and vomiting followed by altered consciousness and drowsiness were the commonest presenting symptoms. Mild TBI accounted for 85.2% of the cases and the majority (92.08%) were treated conservatively (P < 0.005). 93.3% of the cases were categorized as mild head injury upon discharge. The mortality rate was 1.6% in severe TBI cases. CONCLUSION: Children less than 4 years of age were highly affected by TBI. This study gives emergency physicians and neurosurgeons in developing countries an expectation about TBI in pediatric cases and the immediate management to prevent further complications.

Lafora Disease: Report of a Rare Entity.

Lafora disease is a rare, genetic, glycogen metabolism disorder inherited as autosomal recessive characterized by the presence of inclusion bodies, known as Lafora bodies, within the cytoplasm of the cells in the heart, liver, muscle, and skin. Lafora disease presents as a neurodegenerative disorder that causes impairment in the development of cerebral cortical neurons. We present here a case of Lafora disease that presented with progressive myoclonus epilepsy (PME) and investigated at our center. She was diagnosed to have Lafora disease with typical histological findings on skin biopsy and was found to be positive for the pathogenic mutation on genetic testing.
