Consensus statement for the management of incidentally found brain white matter hyperintensities in general medical practice
Med J Aust. 2023 Aug 21. doi: 10.5694/mja2.52079. Online ahead of print.ABSTRACTINTRODUCTION: There is a paradigm shift in our understanding of white matter hyperintensities (WMH) found on brain imaging. They were once thought to be a normal phenomenon of ageing and, therefore, warranted no further investigation. However, evidence now suggests these lesions are markers of poor brain and cardiovascular health, portending an increased risk of stroke, cognitive decline, depression and death. Nevertheless, no specific guidelines exist for the management of incidentally found WMH for general medical practitioners and other clin...

Development and validation of a nomogram for the risk prediction of malignant cerebral edema after acute large hemispheric infarction involving the anterior circulation
ConclusionOur nomogram based on LASSO-logistic regression is accurate and useful for the early prediction of MCE after LHI. This model can serve as a precise and practical tool for clinical decision-making in patients with LHI who may require aggressive therapeutic approaches.

Secondhand smoke linked to dementia
Conclusion Secondhand or passive smoking is known to be detrimental to health and has been associated with increased risk of cardiovascular diseases and cancer. However, it is not yet certain whether it is linked to dementia. Though this large study finds a significant link between secondhand smoke exposure and severe dementia syndromes there are several important limitations to be aware of. Problems with measuring dementia diagnoses The method for diagnosis of dementia used by this study was unusual. Though the researchers assessed each individual using a mental state examination, they went on to diagnose them using a com...

A Woman With a History of Stroke and a Mass in the Aorta
A 65-YEAR-OLD WOMAN presented with an acute onset of slurred speech and left facial droop. She had a past medical history of Raynaud's disease, well-controlled hypertension, and moderate tricuspid regurgitation, which was being followed by serial transthoracic echocardiographic examinations. A duplex ultrasound of the carotid and vertebral arteries was negative, whereas a magnetic resonance imaging scan of her brain revealed a subacute embolic cerebral infarction. A transesophageal echocardiographic (TEE) examination also was performed during the workup, revealing the presence of moderate-to-severe tricuspid regurgitation ...

Determinants of White Matter Hyperintensity Burden in Patients with Fabry Disease (P03.171)
CONCLUSIONS: In FD subjects, the severity of cerebrovascular disease manifested by MRI-detectable WMH is greater than that of general population. WMH burden is associated with CMP in this cohort independently of age, and it may be affected by different disease processes in men and women and at different disease stages. Further studies exploring associations between WMHV, ERT, age- and gender-specific characteristics, as well as longitudinal WMH progression are warranted.Supported by: Genzyme, Sanofi Company; NIH-NINDS K23NS064052.Disclosure: Dr. Rost has received personal compensation for activities with Genzyme Corporatio...

Topography of dilated perivascular spaces in subjects from a memory clinic cohort
Conclusions: The associations of WM-DPVS with lobar microbleeds and BG-DPVS with hypertension raise the possibility that the distribution of DPVS may indicate the presence of underlying small-vessel diseases such as cerebral amyloid angiopathy and hypertensive vasculopathy in patients with cognitive impairment.

Idiopathic intracranial hypertension associated with iron-deficiency anaemia
A 12-year-old Nigerian girl presented to the Emergency Department with headache, dizziness and diplopia. She had a history of menorrhagia. Mild dyspnoea, tachycardia, left sixth cranial nerve palsy and papilloedema (figures 1 and 2) were noted. Body mass index was normal. Full blood count revealed haemoglobin of 4.8 g/dl. The red cells were hypochromic and mircocytic. A CT scan of the brain with venous contrast was normal. A lumbar puncture showed opening and closing pressures of 35 and 33.5 cm H2O, respectively. The diagnosis of idiopathic intracranial hypertension secondary to iron-deficiency anaemia was made. ...

Central Pulse Pressure Is an Independent Determinant of Vascular Remodeling in the Retinal Circulation Retinal Vessels
Pulse pressure has been recognized as a risk factor for stroke. Moreover, it was shown that central pulse pressure relates more strongly to vascular disease and outcome than (peripheral) brachial pulse pressure. Because vascular remodeling in the retinal circulation mirrors the 1 in the cerebral circulation and represents an easy, noninvasive possibility to assess microvascular changes in humans, we analyzed the impact of central pulse pressure on retinal vascular structure in humans. The study cohort comprised 135 nondiabetic patients across a wide range of blood pressure values. Parameter of retinal arteriolar remodeling...

HIMALAIA (Hypertension Induction in the Management of AneurysmaL subArachnoid haemorrhage with secondary IschaemiA): a randomized single‐blind controlled trial of induced hypertension vs. no induced hypertension in the treatment of delayed cerebral ischemia after subarachnoid hemorrhage
This article describes the design of the HIMALAIA trial (Hypertension Induction in the Management of AneurysmaL subArachnoid haemorrhage with secondary IschaemiA), designed to assess the effectiveness of induced hypertension on neurological outcome in patients with DCI after SAH. AimsTo investigate whether induced hypertension improves the functional outcome in patients with delayed cerebral ischemia after SAH. DesignThe HIMALAIA trial is a multicenter, singe‐blinded, randomized controlled trial in patients with DCI after a recent SAH. Eligible patients will be randomized to either induced hypertension (n = 120) or t...

A practical prediction model for early hematoma expansion in spontaneous deep ganglionic intracerebral hemorrhage
Conclusions: The presented model (HV>16, HH, 1.5h-SBP>160) can be a practical tool for prediction of ICH growth in the acute stage. Further prospective studies are warranted to validate the ability of this model to predict clinical outcome.

Trigeminal neuralgia after pontine infarction affecting the ipsilateral trigeminal nerve
A 57-year-old man presented with numbness, paraesthesia and lancinating pain on the left side of the face, which had developed suddenly 10 days previously. He had hypertension and no history of headache. His facial pain was characterised by a brief electric shock-like pain, which was evoked by light stimuli, and also occurred spontaneously. A neurological examination showed a mild decrease in sensation on the left side of the face, mainly with V2 and V3 distribution, and on the left oral cavity, including the tongue and buccal mucosa. Other neurological examinations were normal, including the corneal reflex and the mo...

Successful outcome after traumatic rupture and secondary thrombosis of the superior sagittal sinus
A 15-year-old adolescent was admitted to the emergency department after a car accident because of severe traumatic brain injury. Upon arrival, he was sedated and intubated because of a Glasgow Coma Scale score below 8. He had isocoria with reactive pupils. An occipital puncture wound (diameter 2 cm) was profusely bleeding. His blood pressure was 85/45 mm Hg. Laboratory values identified a haemoglobin level of 4.6 mmol/l. A CT scan of the brain demonstrated a comminuted-depressed fracture of the parietal bone in the midline with a rupture of the superior sagittal sinus (SSS) and secondary thrombosis (fig...
