A Patient with a Brain Abscess Presenting as an Acute Stroke.

A brain abscess is an enclosed focal infection within the brain that is either initiated by haematogenous seeding or spreads contiguously from oto-sinusitis, local trauma or neurosurgery. We describe the case of a 71-year-old man presenting with acute confusion and unilateral neurology in the absence of systemic signs of sepsis or associated laboratory biomarkers. While his initial clinical presentation mimicked an acute cerebrovascular event or brain tumour, he was subsequently diagnosed with a particularly large spherical temporal lobe brain abscess of 5 cm diameter on neuroimaging. This abscess was treated successfully with craniotomy, evacuation and a prolonged course of anti-microbials, enabling him to return to his pre-morbid level of functioning. His prolonged course of anti-microbials was complicated by candidaemia and colonisation of an indwelling central venous catheter that was treated successfully with anti-fungals. LEARNING POINTS: A high index of suspicion for brain abscess should be maintained when a ring-enhancing lesion is found on neuroimaging, even in the absence of signs of sepsis or associated laboratory biomarkers.Commensal yeasts may colonise indwelling lines in patients treated with long-term broad-spectrum antibiotics.Distracting concomitant diagnoses may delay recognition of the primary pathological process.

Abbreviated lipid guidelines for clinical practice : Based on ESC lipid guidelines 2019 and ESC cardiovascular disease prevention in clinical practice guidelines 2021.

BACKGROUND: Lipid disorders are now considered causal for atherosclerotic cardiovascular disease (ASCVD) which remains one of the most important contributors to morbidity and mortality in the developed world. Identification and early treatment of lipid disarrays remains the cornerstone of good clinical practice to prevent, halt and even reverse ASCVD. Guidelines for lipid management are imperative to help promote good clinical practice. Given the detail involved in comprehensive guidelines and the multiple areas of knowledge required by clinical practitioners, abbreviated, easy to understand, practical versions of guidelines are required to ensure dissemination of the most important information. The recent ESC lipid guidelines 2019 and the ESC guidelines on CVD prevention in clinical practice 2021 (1,2), provide an excellent detailed summary of all the latest evidence supporting lipid interventions that reduce ASCVD. METHOD: We therefore developed a single-page document with hyperlinks to help practitioners gain easy access to practical information on lipid management. It has been developed for future electronic use in clinical practice. CONCLUSION: It is presented here in a tabular format together with printable versions of the associated hyperlinks that provide the additional information required in decision making. It is hoped to audit the impact of this approach to help guide future ways of disseminating the latest clinical guideline updates.

Amphetamine-induced cardiomyopathy complicated by embolic stroke: a case report.

BACKGROUND: Amphetamine use causes cardiomyopathy via catecholamine-mediated effects such as tachycardia, hypertension, vasoconstriction, and direct cardio-toxic effects. Traditionally, an increased risk of haemorrhagic stroke is associated with amphetamine use. However, up to one-third of stimulant-associated cardiomyopathy patients have left ventricular (LV) thrombus formation leading to an increased risk of systemic embolization. We report a case of amphetamine-induced cardiomyopathy complicated by embolic stroke secondary to LV thrombus. CASE SUMMARY: A 38-year-old man with 6-month history of sustained amphetamine use presented to the emergency department with left-sided weakness, facial droop, and dysarthria. Angiography confirmed right middle cerebral artery thrombus. Prompt mechanical thrombectomy yielded full neurological recovery. Dyspnoea prompted transthoracic echocardiography showing dilated cardiomyopathy with an ejection fraction of 5% and LV thrombus. Anticoagulation was initiated with warfarin as well as pharmacological therapy for heart failure with reduced ejection fraction including bisoprolol, spironolactone, loop diuretic, and sacubitril/valsartan. He was discharged successfully following resolution of ventricular thrombus and medical management of heart failure. Clinical recovery was hampered by psychosocial factors resulting in non-adherence to medical therapy and continued amphetamine use. CONCLUSION: Sustained amphetamine use can result in severe dilated cardiomyopathy with LV thrombus formation and embolic complications such as ischaemic stroke. Avoidance of amphetamines in conjunction with guideline-directed pharmacological management are key components of therapy. However, psychosocial factors can exert significant influence on recovery.

Blood pressure control in hypertensive patients in Irish primary care practices.

In Ireland, cardiovascular disease is a major cause of death. However, blood pressure (BP) goal achievement is unsatisfactory. The authors aimed to document BP control and increase awareness. A total of 1534 patients were enrolled in the study, with a mean age of 64.7+/-11.9 years (53.8% women). Duration of hypertension was 8.7+/-7.7 years, and 14.6% had diabetes, 13.8% had coronary artery disease, and 40.5% were taking antihypertensive monotherapy. beta-Blockers (39.8%), angiotensin-converting enzyme inhibitors (32.2%), and angiotensin receptor blockers (22.0%) were prescribed most frequently. Mean BP was 136.0+/-6.1 mm Hg/89.5+/-5.0 mm Hg in nondiabetic patients (48.6% <140/90 mm Hg) and 131.0+/-7.4 mm Hg/81.7+/-4.6 mm Hg in diabetic patients (16.7% <130/80 mm Hg). Diet, exercise, and lifestyle modifications (63.5%) were frequently recommended. Increased patient awareness and compliance together with the adherence of physicians to current guidelines and greater willingness to take action in patients with uncontrolled hypertension should help in improving BP control and thus reduce cardiovascular risk.
