Comprehensive Mapping and Dynamic Monitoring of the Temporal Branch of the Facial Nerve in Complex Cranial Reconstruction Surgery and Revision Cranioplasty.

Facial nerve (FN) injury is a significant risk during complex cranial reconstruction surgeries, especially in revision cases where normal anatomy is distorted. The authors introduce a technique to mitigate FN injury, including preoperative FN mapping, intraoperative FN mapping, and continuous FN monitoring. Preoperative mapping uses a handheld ball-tip stimulator to elicit compound muscle action potentials (CMAP) in the frontalis muscle.

Staged cerebral and brachiocephalic bypass in a patient with MCA and brachiocephalic steno-occlusion.

Brachiocephalic steal is a rare phenomenon that may lead to hemodynamic abnormalities in the ipsilateral vertebral and carotid arteries. Current treatment includes management of vascular risk factors, endovascular stenting, and surgical management depending on the severity of symptoms. We describe a patient with multiple vascular risk factors who presented with mild neurological symptoms and chronic right arm weakness associated with concurrent brachiocephalic steal and right MCA M1 stenosis on neuroimaging.

Anticoagulation in venous thromboembolism for the general physician.

Venous thromboembolism (VTE) is frequently encountered across various specialties. The management of VTE has become more nuanced, requiring consideration of several factors when deciding on the choice and duration of anticoagulation. This evidence-based review article summarises the current practice and evidence behind anticoagulation in VTE, incorporating national and international guidelines.

Drug-induced secondary haemophagocytic lymphohistiocytosis in hairy cell leukaemia.

Haemophagocytic lymphohistiocytosis (HLH) is a rare, aggressive, excess immune activation syndrome. Diagnosis can be challenging due to its several clinical mimics including sepsis. There are multiple aetiologies of HLH; in adults, it is most commonly triggered by infection, malignancy, drugs and autoimmune processes.
