Background: Hump-nosed pit vipers (Genus: Hypnale) are medically important snakes in Sri Lanka and South India. Merrem's Hump-nosed pit viper (Hypnale hypnale) frequently leads to potentially fatal envenomings in Sri Lanka and India. Venom-induced consumption coagulopathay (VICC), local envenoming and acute kidney injury (AKI) are the commonest effects of the envenoming by this snake.
Case Presentation: We report a previously unreported presentation of H. hypnale envenoming, with an isolated urinary salt loss leading to moderate hyponatraemia resulting seizures. The patient was treated with careful fluid and electrolyte management. No antivenom is currently available for H. hypnale envenoming.
Conclusion: In the absence of any evidence of venom induced consumptive coagulopathy, acute kidney injury and cerebral haemorrhage, we hypothesize that this effect is likely due to the presence of a natriuretic peptide in H. hypnale venom, similar to the natriuretic peptides identified in few other snake venoms.

Trigeminal neuralgia (TN) is chronic pain caused by damage to the somatosensorial system on the trigeminal nerve or its branches, which involves peripheral and central dysfunction pain pathways. Trigeminal pain triggers disruptive pain in regions of the face, including within and around the mouth. Besides clinical experiences, translating the language of suffering into scientific terminology presents substantial challenges.

The leucine-rich glioma-inactivated protein 1 (LGI1) antibody-related autoimmune encephalitis can occur alone or in the setting of a malignancy and manifest with faciobrachial dystonic seizures (FBDS), cognitive decline, hyponatremia, and neuropsychiatric disorders. The importance of differentiating this entity from acute delirium cannot be overemphasized. This review provides a detailed account of a 71-year-old man with previous diagnosis of lung cancer who presented with subacute onset behavioural changes, urinary retention, and FBDS.

Objective: Since the recent development of stereotactic ablation surgery, which can provide good seizure outcomes without limitations in size or location, conventional classification systems have become unsuitable for surgical guidance. The present study aimed to evaluate the validity of a newly proposed classification system focusing on the attachment pattern.
Methods: This retrospective study investigated 218 patients with hypothalamic hamartomas who underwent MRI-guided stereotactic radiofrequency thermocoagulation and were followed for at least 1 year after their last surgery.

Background: Seizures are one of the most common neurological complications encountered in the intensive care unit (ICU). They can occur in the background of exacerbation of a known neurological disease or secondary to non-neurological conditions such as sepsis and metabolic disturbances. However, there is a paucity of literature on the incidence and pattern of new-onset seizures in ICUs.

Background: Autoimmune limbic encephalitis (ALE) is a rare inflammatory disorder characterised by a subacute onset, usually within weeks. The presence of multiple neuropsychiatric symptoms such as seizures, short-term memory deficits, anxiety and depression often leads to misdiagnosis as another medical condition, contributing to poor prognosis and reduced long-term survival.
Case Description: A 60-year-old man, with no chronic illnesses, presented at the emergency department with daily episodes of palpitations, shivering, piloerection and a sense of impending doom lasting two months.
