Apparent stroke with fever may be bacterial meningoencephalitis, while evolving systemic clues can overturn a sarcoidosis diagnosis.
Fever, headache, neck pain and focal neurological deficit can reflect bacterial meningoencephalitis with cerebral infarction, so apparent stroke must not delay antimicrobial treatment.
The acute-care material begins with altered mental status accompanied by focal neurological signs. Fever, headache, neck pain, aphasia, unilateral weakness or sensory loss and rapid deterioration can represent bacterial meningoencephalitis rather than uncomplicated ischaemic stroke. Capillary glucose remains an immediate bedside check, but a normal early non-contrast CT does not exclude meningitis, encephalitis, early infarction, abscess or raised intracranial pressure.
When bacterial meningitis is strongly suspected, blood cultures, empiric meningeal-dose antibiotics and dexamethasone should not be delayed while imaging or lumbar-puncture safety is considered. Recent otitis media or sinus infection may provide a clue to pneumococcal infection. Coma, persistent focal deficit or markedly raised CSF opening pressure should prompt early neurology and neurocritical-care escalation, with MRI helping to identify meningitis-associated infarction or other complications.
A second diagnostic-reasoning case shows why an existing label must be revisited when the clinical course no longer fits. Hypercalcaemia with hilar lymphadenopathy may suggest granulomatous disease, but persistent fever, recurrent deterioration, monoclonal cryoglobulins, progressive neuropathy and longstanding sicca symptoms broaden the differential. Sjögren’s disease increases B-cell lymphoma risk, while an IgM monoclonal protein and demyelinating neuropathy should raise consideration of anti-MAG disease. Tissue diagnosis and monoclonal-protein investigation become more useful than repeatedly treating presumed sarcoidosis.
Primary-care learning includes illness anxiety disorder. Appropriate clinical assessment remains necessary because genuine disease can coexist, but repeated testing may reinforce reassurance seeking once serious pathology has been reasonably excluded. Asking about body checking, internet searching, healthcare avoidance and the specific feared illness helps define the pattern. Validation, agreed scheduled reviews, explicit safety-netting and CBT provide a more sustainable approach than repeated reactive investigation.
The remaining episodes broaden follow-up and prevention. Anxiety and depression should be screened for routinely in epilepsy, particularly around anti-seizure medication changes. Cancer survivors with fatigue, hot flushes, low libido or erectile dysfunction may need repeat morning testosterone with luteinising hormone and follicle-stimulating hormone, alongside assessment of bone, metabolic and cardiovascular risk. In adolescents, gradual activity-related anterior knee pain with focal tibial tuberosity tenderness suggests Osgood-Schlatter disease; sudden severe pain or loss of function should instead raise concern for tibial tuberosity avulsion.
The evidence and systems items add two further cautions. Fenebrutinib trial findings require interpretation of non-inferiority, population and safety rather than assuming that oral administration means lower risk. Global surgery partnerships should be judged by local leadership, patient benefit, shared recognition and protection of local learner opportunities, not only by the experience of visiting teams.
General surgery, medical-education and global-health teams get a systems-focused discussion of power in cross-border clinical work. Funding, mobility, credentialing, authorship and publication access are linked to local leadership, protection of local learners and patient access to timely surgical decision-making.
Emergency, infectious-diseases and neurology clinicians get a diagnostic-reasoning case involving headache, neck pain, fever, aphasia and focal neurological deficit. It shows how bacterial meningoencephalitis can resemble stroke, produce raised intracranial pressure and cause cerebral infarction through meningitis-associated vascular complications.
Rheumatology, haematology and neurology teams get a complex case linking hypercalcaemia, hilar lymphadenopathy, cryoglobulinaemic vasculitis and progressive demyelinating neuropathy. Longstanding sicca symptoms, monoclonal immunoglobulin and anti-MAG neuropathy challenge an earlier sarcoidosis diagnosis and point towards lymphoma associated with Sjögren’s disease.
General-practice and mental-health clinicians get a practical approach to persistent fear of serious disease despite appropriate assessment. Validation, scheduled review, careful limits on repeat investigation and cognitive behavioural therapy are used to reduce reassurance cycles without dismissing genuine symptoms.
Neurology and critical-appraisal readers get a trial update on oral fenebrutinib for primary progressive multiple sclerosis. Non-inferiority to ocrelizumab, possible benefit in non-relapsing progression and the convenience of oral treatment are balanced against liver-enzyme abnormalities, biochemical Hy’s law signals and a mortality imbalance.
Neurology and psychiatry clinicians get a brief screening framework for anxiety and depression in epilepsy. GAD-2, PHQ-2 and the epilepsy-specific NDDIE can support assessment at diagnosis, during treatment changes and throughout follow-up, particularly when mood effects are not volunteered.
Oncology, endocrinology and sexual-health teams get a survivorship update on testosterone deficiency after cancer treatment. Androgen deprivation therapy, chemotherapy, immunotherapy and orchidectomy are linked to fatigue, hot flushes, sexual symptoms, bone health, metabolic risk and the distinction between primary and secondary hypogonadism.
Paediatric, adolescent-health and orthopaedic clinicians get a focused review of activity-related anterior knee pain. A tender tibial tuberosity lump and pain with resisted knee extension support the diagnosis, while activity modification, ice, anti-inflammatory analgesia and later physiotherapy guide management.
When focal neurological signs occur with fever, headache, neck pain or rapid encephalopathy, check glucose, obtain blood cultures and start empiric meningeal-dose antibiotics with dexamethasone promptly when bacterial meningitis is strongly suspected. Do not use a normal early CT as reassurance. In recurrent health-anxiety consultations, agree structured follow-up rather than repeating investigations reflexively. In adolescent anterior knee pain, palpate the tibial tuberosity and test resisted extension.
An adult presents with fever, headache, neck pain, non-fluent speech and right-sided weakness, then becomes increasingly drowsy. What immediate management principle is most important?
Treat possible bacterial meningoencephalitis promptly. Obtain blood cultures and give empiric meningeal-dose antibiotics with dexamethasone without waiting for lumbar puncture when imaging or safety assessment must occur first.
A patient repeatedly seeks investigation for pancreatic cancer despite appropriate negative assessment, checks bodily sensations throughout the day and gains only brief reassurance after each consultation. What management approach is most appropriate?
Validate the distress, agree scheduled clinical reviews with clear safety-netting, limit unnecessary repeated testing and offer CBT or another appropriate psychological intervention.
A 13-year-old who plays basketball has gradual anterior knee pain, a tender hard lump over the tibial tuberosity and pain with resisted knee extension. What is the likely diagnosis and initial management?
The likely diagnosis is Osgood-Schlatter disease. Temporarily reduce provoking activity, use ice and appropriate anti-inflammatory analgesia, then introduce stretching or physiotherapy as acute pain settles.
