We aim to report 3 cases of central nervous system (CNS) vasculitides, in which high-resolution magnetic resonance vessel wall imaging (HR-VWI) findings were instrumental in the diagnosis and management.

Differentiating glaucomatous and non-glaucomatous optic neuropathy can be challenging even to an experienced clinician and it is even more complex to identify early ophthalmic manifestation of neurological lesions when the optic nerve is already jeopardized by advanced glaucoma. This is a case of a patient with juvenile open-angle glaucoma with advanced glaucomatous cupping who developed an intracranial tuberculoma and subsequent obstructive hydrocephalus. Subtle edema identified in an almost totally damaged nerve, coupled with a history of headache and tinnitus, was the clinching factor prompting early treatment in the form of ventriculoperitoneal shunting and antituberculous therapy. Detailed history, systematic clinical exam, and appropriate imaging are imperative in reducing morbidity and sometimes mortality associated with these neurological conditions.

A number of studies show that acupuncture may help with labour and delivery. An NHS maternity acupuncture service providing birth preparation acupuncture has assessed its routine hospital maternity annual data from 2014 to 2016 to see what effect it had on labour and delivery outcomes. The data from this service was analysed and women who had birth preparation acupuncture were compared with those who did not receive it. Maternal age, parity and socio-economic status were considered confounders and were adjusted for in the analysis. Women who received acupuncture had more normal births (less surgical births) [OR 0.76 (0.64, 0.91)], required less intrapartum analgesia [OR 0.74 (0.63, 0.86)], fewer components of an induction of labour [OR 0.74 (0.61, 0.91)] and a reduced length of a hospital stay [OR 0.91 (0.87, 0.95)]. The patients highly valued the availability of acupuncture within the maternity service as it enhanced their patient journey.Impact statement Numerous studies provide evidence for the effects of acupuncture in normalising pregnancy and birth. These effects include musculoskeletal preparation of the pelvis, cervical ripening, enhancing endogenous oxytocin release, and analgesic properties. Our analysis shows that women who received birth preparation acupuncture had fewer surgical births, required less intrapartum analgesia, less components of induction of labour and had a reduced length of hospital stay, supporting the use of maternity acupuncture in normalising birth outcomes. The findings show that acupuncture, by potentially normalising birth, may lead to reductions in costs of service. Further, additional research is required to see whether acupuncture is cost effective and could have an adjunctive role as a complementary therapy for improving birth outcomes and a woman's experience of childbirth.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most common analgesics used for pain relief. Adverse effects of NSAIDs range from gastrointestinal tract disturbances to increased risk of bleeding, renal injury, and myocardial infarction. In Malaysia, the research productivity of NSAIDs is not well explored.

A 40-year-old man presents to the emergency department with headache, nausea and paresthesias, with subsequent fever and mental status change. Magnetic resonance imaging showed increased fluid-attenuation inversion recovery signal involving multiple areas of the brain, including the pons. This case takes the reader through the differential diagnosis of rhombencephalitis (inflammation of the hindbrain) with discussion of the unanticipated ultimate diagnosis and its treatment.

Posterior reversible encephalopathy syndrome (PRES) is an acute neurological condition with unknown global incidence, variable clinical presentation, and prognosis.

Myelin oligodendrocyte glycoprotein (MOG) antibody-related encephalomyelitis is an increasingly recognized entity with heterogeneity in phenotype. Among all clinical phenotypes, encephalitis restricted to cerebral cortex might be most easily ignored and under-estimated type. Here, we described two cases of cerebral cortical encephalitis with MOG seropositivity to facilitate the awareness of the manifestations of the disease. In case 1, the patient presented with headaches and fevers turned out to have elevated CSF cells and cerebral cortical FLAIR hyperintense lesions in brain MRI. He was treated as intracranial infection during his first and second admission and fully resolved when discharged. During the patient's third admission, the patient experienced a seizure, and we found cerebral cortical FLAIR hyperintensity again and MOG antibody was positive in the serum. Therefore, we considered the patient suffered from MOG antibody encephalitis. In case 2, the patient also had headache, fever, and experienced a seizure. MOG antibody was positive in the serum and brain MRI showed cortical hyperintense lesions. Both the patients were young man, response well to corticosteroids and recovered completely. The two cases suggested that encephalitis, especially benign recurrent unilateral cerebral cortical encephalitis with epilepsy, might be a special phenotype of MOG antibody-associated disorders.

Little is known whether the duration of opioid use influences the concentrations of pro- and anti-inflammatory cytokines.

Cannabis has been used as a medicine for millennia. Prohibition in the mid-20th century precluded early scientific investigation. 'Cannabis' describes three separate forms – herbal cannabis, 'hemp' products, pharmaceutical-grade regulated cannabinoid-based medical products (CBMP). In Australia, CBMP became available for prescription in November 2016. Herbal cannabis with Δ9-tetrahydrocannabinol (THC), which is illegal, and cannabidiol (CBD) in herbal extracts, are both unregulated and unreliable sources of cannabinoids. The endocannabinoid system (ECS), delineated in the late 1990s, has increased the understanding and interest in research for appropriate clinical indications. The ubiquitous ECS has homeostatic and anti-inflammatory effects and comprises cannabinoid receptors, endocannabinoids and degrading enzymes. Phytocannabinoids are partial agonists of the ECS. In pre-clinical studies, THC and CBD produce beneficial effects in chronic pain, anxiety, sleep and inflammation. Systematic reviews often conflate herbal cannabis and CBMP, confusing the evidence. Currently large randomised controlled trials are unlikely to be achieved. Other methodologies with quality end-points are required. Rich, valuable high-quality real-world evidence for the safe and effective use of CBMP provides an opportunity to examine benefits and potential harms. Evidence demonstrates benefit of CBMP in multiple sclerosis, chronic neuropathic pain, chemotherapy induced nausea and vomiting, resistant paediatric epilepsy, anxiety and insomnia. CBMP are well tolerated with few serious adverse events. Additional clinical benefits are promising in many other resistant chronic conditions. Pharmaceutical grade prescribed CBMP has proven clinical benefits and provides another clinical option in the physician's pharmacopeia.
