ABSTRACT
Stroke mimics typically involve non-vascular disease processes, accounting for approximately half of hospital admissions for suspected stroke. These mimics may manifest as functional (conversion) disorders or indicate other neurological or medical conditions, including hypoglycemia, brain tumors, toxic poisoning, migraines, sepsis, seizures, and electrolyte imbalances, which can imitate stroke symptoms, making the diagnosis complex. In this report, we present a unique case of a man in his sixties who developed acute postoperative hyponatremia, an electrolyte abnormality frequently encountered but rarely presented with focal neurological deficits. This condition resulted in facial asymmetry and hemiparesis; however, the remarkable outcome was that these deficits were completely resolved once the hyponatremia was corrected.
ABSTRACT
Marchiafava-Bignami disease (MBD) is a rare neurological disorder characterized by demyelination and necrosis of the corpus callosum. The non-specific signs and symptoms associated with MBD including dysarthria, impaired walking, pyramidal signs, primitive reflexes, seizures, incontinence, sensory symptoms, gaze palsies, and altered mental state result in a challenging diagnosis. Here, we report the case of a 64-year-old female presenting with dizziness, gait ataxia, and a history of recurrent falls for several months. Initial blood tests indicated anaemia, hypokalemia, hypomagnesemia, and mildly elevated inflammatory markers. Her presentation was initially attributed to a multifactorial aetiology, including a urinary tract infection, orthostatic hypotension, and electrolyte imbalances; however, on correction of reversible causes, her symptoms persisted. Moreover, further examination revealed right-hand dysdiadochokinesia. Subsequent brain MRI revealed fluid-attenuated inversion recovery hyperintensity within the corpus callosum and a right-sided pericallosal white matter hyperintensity. Neuro-radiology multidisciplinary team reported these findings consistent with MBD. Management with vitamin B supplementation was promptly initiated alongside alcohol cessation advice. She was also reviewed by physiotherapy teams. This case adds to the paucity of literature on MBD.
ABSTRACT
Diuretics have an essential role in the management of heart failure (HF). However, each drug has its own benefit and side effect. Side effects include fluid, electrolyte abnormalities, and acid-base disturbance. These adverse effects of diuretics predispose patients to serious cardiac arrhythmias and may increase the risk of arrhythmic mortality. Herein, we aim to summarize the relative efficacy and safety of all available diuretics used in the treatment of patients with HF. In June 2017, a systematic electronic database search was conducted in nine databases. All randomized controlled trials (RCTs) comparing the different diuretics used in HF were included for meta-analysis. The protocol was registered in Prospero with CRD42018084819. Among the included 54 studies (10,740 patients), 34 RCTs were eligible for quantitative network meta-analysis (NMA) and traditional meta-analysis while the other 20 studies were qualitatively analyzed. Our results showed that azosemide and torasemide caused a significant reduction in brain natriuretic peptide (BNP) level. Torasemide also caused a significant decrease in collagen volume fraction (CVF) and edema. No significant difference between the agents concerning glomerular filtration rate (GFR), water extraction, and sodium excretion was demonstrated. Regarding side effects, no significant difference among diuretics was observed in terms of hospital readmission and mortality rates. Diuretics are the main treatment of hypervolemia in HF patients. The choice of appropriate diuretic is essential for successful management and is mainly guided by patient clinical situations and the presence of other co-morbidities.
