Resolved neurological symptoms can still mark a time-critical TIA. This review keeps the focus on sudden focal symptoms, common mimics, early aspirin when appropriate, urgent imaging, vascular assessment, ECG and mechanism-based prevention.

Complex atrial fibrillation is framed around the decision that changes management: rhythm control, rate control, cardioversion, ablation or pacing. Pre-excitation, pregnancy, repaired Tetralogy of Fallot and tachy-brady syndrome each need a more precise description than chronic AF.

Paediatric non-shockable cardiac arrest is treated as a timing and task-allocation problem, not a rigid airway-versus-adrenaline sequence. The same Primary Survey also checks where HEMS may support major trauma care and how online surveys can be distorted by impostor responses.

Anal pain, bleeding, itching or a lump can look like piles while still needing anal cancer awareness. The focus is HPV-related high-grade AIN, people assigned female at birth, digital anorectal examination, high-resolution anoscopy and risk factors such as HIV, smoking and immunosuppression.

Painful parotid swelling after a flu-like prodrome should bring mumps into view, even before complications appear. Key checks include MMR history, oral fluid PCR, supportive care, notification, and screening for abdominal, testicular or neurological symptoms.

Pancreatic cancer radiotherapy is presented as palliation, consolidation after systemic therapy, neoadjuvant treatment in selected borderline resectable disease and possible oligometastatic control. The clinical decision is selection: metastatic status, chemotherapy response, luminal gastrointestinal invasion, nutritional burden and realistic treatment goals.

Memory concerns in older former football players need exposure history alongside cognitive assessment. The research link is specific: inflammatory biomarkers, limbic white matter microstructure and memory performance are associated, but biomarkers do not diagnose chronic traumatic encephalopathy in an individual.
