Neurosyphilis is a broad term used to describe an infection caused by Treponema pallidum in the central nervous system. While this was a common cause of stroke in the 19th century, it saw a decline after the introduction of penicillin. However, in the recent past, there has been an increase in the incidence of syphilis, especially with HIV coinfection. Neurosyphilis results from an untreated primary syphilis. Neuropsychiatric disorder appears to be the commonest manifestation followed cerebrovascular accident, myelopathy, ocular disease and seizure. Known as the 'great imitator', this entity, however, may be easily missed if not for a high index of suspicion. This is especially so because of its similar presentation to other more common clinical conditions. We describe the case of a 39-year-old man displaying acute global aphasia and right-sided facial weakness in keeping with a left middle cerebral artery infarct. This was confirmed with computed tomography of the brain, and subsequently, further investigations revealed a diagnosis of neurosyphilis. The patient was treated with intravenous benzylpenicillin and recovered well with treatment.
Guillain-Barré syndrome (GBS) is an acute immune-mediated demyelinating disease. Early recognition of this disease is crucial as it can progress to life-threatening conditions such as respiratory failure or autonomic dysfunction. Typical clinical manifestations of GBS include progressive weakness of the limbs, bulbar, facial muscles and ophthalmoplegia. Sensory level and bladder dysfunction are more suggestive of acute myelopathy. We report a case of GBS presenting with acute urinary retention and T6 sensory level, which was successfully treated with plasma exchange.
Percutaneous vertebroplasty (PV) involves injection of polymethylmethacrylate bone cement into vertebral body for relief of pain and strengthening of bone in symptomatic vertebral compression fractures.Passage of bone cement into vertebral venous plexus and then into the lungs is a rare and serious complication of PV. The reported incidence up to 26%.We present an incidental finding of pulmonary cement embolism (PCE) after PV. A 68-year-old woman with history of PV 3 years previously for T11 osteoporotic fracture presented to us with cough for 3 weeks following choking on a fish bone.Chest X-ray showed left lower zone consolidation and a high-density opacity in a tubular branching pattern, corresponding to pulmonary arterial distribution. Contrasted computed tomography of the thorax showed segmental pulmonary cement embolism of both lungs and left lower lobe consolidation.She underwent bronchoscopy with findings of a purulent secretion from the left lower lobe. Her symptoms resolved after 2 weeks of antibiotics. She was managed conservatively for the PCE as she remained asymptomatic.This case highlights the need for a standard post-PV chest X-ray, as patients with cement embolisms can be completely asymptomatic. Measures to minimise the risk of pulmonary cement embolisms during PV need to be taken.
Tuberculosis is an airborne multisystemic disease which primarily infects the lungs. Isolated tuberculous arthritis is rare. We present a case of a 41-year-old woman with a known case of lupus nephritis class IV who complained of pain and swelling over her left ankle joint for several months. She was treated for rheumatoid arthritis and was started with immunosuppressive agents. However, she did not improve with treatment and was later diagnosed with tuberculous arthritis based on a molecular study from joint aspiration. She was started on antituberculosis medication and showed improvement. We highlight the challenges in reaching the diagnosis and the importance of including tuberculous arthritis in differential diagnoses in cases with persistent ankle swelling.
Pain is common among older people. However, it remains underrecognised and under-treated. A comprehensive assessment of pain involves identifying its cause, establishing its severity, determining its impact on the person experiencing it and reviewing the person's response to treatment. Addressing their pain requires a different approach compared to a younger person because there is usually concomitant frailty, multimorbidity, polypharmacy, sensory deficits and cognitive impairment. This review will summarise a comprehensive approach to pain management in the older person.
