A 47-year-old man, positive for SARS-CoV-2, was diagnosed with acute coronary syndrome (ACS) complicated by myocarditis on a background of COVID-19 pneumonia. He was medically treated for ACS; however, 3 days into his admission, the patient developed neurological complications confirmed on MRI of the brain. MRI showed established infarcts involving a large part of the left temporal lobe and right occipital lobe, with minor foci of micro-haemorrhagic transformation in the left temporal lobe. A left ventricular mural thrombus was then confirmed on echocardiogram, and this was attributed as the cause of his neurological infarct. Further infarctions in the kidneys and spleen, and thrombi in the superior mesenteric and left femoral artery were also identified on imaging of the abdomen. The left ventricular mural thrombus was removed surgically via a midline sternotomy incision under general anaesthesia. Surgery was successful and the patient was discharged to a rehabilitation centre.

Background: Case 1: a 59-year old man presented to our service with 4 years of progressive cognitive and behavioral symptoms. He became forgetful and experienced difficulties managing his payments. After 4 years he could no longer recognise his relatives. Cognitive assessment showed a mini-mental status examination of 17/30. MRI and SPECT revealed respectively focal atrophy and hipoperfusion of the frontal regions and anterior right temporal lobe. Case 2: a 72-year-old woman was brought to evaluation with a 5-years history of progressive language and behavioral deterioration. Her family reported early speech errors and behavioral changes, with a marked aggressiveness, ritualistic behaviors and hyperorality. Cognitive evaluation revealed a MMSE of 6/30 mainly due to a relatively fluent afasia. Brain MRI showed asymmetric cerebral atrophy, more prominent in the anterior left temporal lobe. Objective: N/H Methods: N/H Results: N/H Conclusion: We describe two cases of suspected frontotemporal dementia (FTD) syndromes. The left ATL may receive proportionately more input from the lexical and phonological centers subserving word processing. The right ATL may receive more input from right-lateralized emotion processing hubs. Focal atrophy of the left anterior temporal lobe has been associated with the semantic type of primary progressive aphasia evolving to semantic dementia. In contrast, focal atrophy of the right temporal lobe has recently been described as a controversial entity reported as the right temporal variant of FTD.

"Dyslexia is one of the most frequent specific learning disorders which has often been associated with deficits in phonological awareness mainly caused by auditory and visual inabilities to recognize and discriminate phonemes and graphemes within words. Neuroimaging techniques like EEG recordings have been widely used to assess hemispheric differences in brain activation between students with dyslexia and their typical counterparts. Although dyslexia is a lifelong disorder which persists into adulthood, very few studies have been carried out targeting in adult population. In this study, we examined the brain activation differences between 14 typical (control group) and 12 university students with dyslexia (experimental group). The participants underwent two tasks consisting of 50 3-word groups characterized by different degrees of auditory and visual distinctiveness. The whole procedure was recorded with a 14-sensor sophisticated wearable EEG recording device (Emotiv EPOC+). The findings from the auditory task revealed statistically significant differences among the two sets of groups in the left temporal lobe in ?, ? and ? rhythms, in the left occipital lobe in ? rhythm, and in the right prefrontal area in ?, ? and ? rhythms, respectively. The students with dyslexia reported higher mean scores only in ? rhythm in the left temporal lobe, and in ?, ? and ? rhythms in the right prefrontal area. Concerning the visual task, statistically significant differences were evident in the left temporal lobe in ?, ? rhythms, in the occipital lobe in ?, ? and ? rhythms, in the parietal lobe in ? rhythm, and in the right occipital lobe in ?, ? and ? rhythms. The students with dyslexia reported higher mean scores only in the ? rhythm of both the left and right occipital lobe. The results indicate that there are differences in the hemispheric brain activation of students with or without dyslexia in various rhythms in both experimental conditions, thus, shedding light in the neurophysiological discrepancies between the two groups. It also lays great emphasis on the necessity of carrying out more studies in adult population with dyslexia."

A 56-year-old man was brought to our hospital by his family, seeking medical treatment for the patient’s long-standing progressive word-finding difficulties, forgetfulness, agitation and social withdrawal. After multiple previous physician consultations, the patient was mistakenly diagnosed with epilepsy and prescribed multiple anticonvulsants, to which his above mentioned symptoms were unresponsive. His condition progressed over the next 10 years, resulting in severe cognitive impairments and a complete dysfunctionality. An electroencephalogram (EEG) assessment revealed persistent spike and wave activity in the left temporal lobe. Brain MRI revealed multiple small bright T2 and fluid attenuated inversion recovery (FLAIR) foci within the white matter of both cerebral hemispheres surrounding the ventricular system, as well as some widening of extra-axial cerebrospinal fluid spaces. The patient was finally diagnosed with early-onset dementia and temporal lobe epileptiform abnormalities. This case emphasises the need for diagnostic consideration of dementia in cognitively impaired patients, even when they are not of an advanced age.

A 61-year-old man was admitted to hospital with severe occipital headache and weakness and numbness of the left arm. His electrocardiograms showed changes hinting at acute coronary syndrome (ACS). However, in view of his clinical presentation, he underwent tests for likely subarachnoid haemorrhage, but this was ruled out. The next day, he was referred to cardiology. A transthoracic echocardiogram showed reduced left ventricular systolic function along with regional wall motion abnormalities involving inferoposterior walls. The patient was treated as per the protocol for ACS. A dobutamine stress echocardiogram confirmed inferior myocardial infarction with evidence of myocardial viability in the affected left ventricular segments. Subsequent investigations confirmed three-vessel coronary artery disease and reduced left ventricular systolic function. The patient underwent successful coronary artery bypass grafting.

Prognostic Utility

Background: Acute coronary syndrome (ACS) is the leading cause for morbidity and mortality in developed countries. Numerous groups have explored single and multiple biomarker strategies to identify diagnostic prognosticators of ACS which will improve our ability to identify high-risk individuals. Matrix metalloproteinase (MMP-9) is one potential biomarker which has been widely studied in ACS. Recent reports have showed the prognostic utility of MMP-9, but due to inconsistent results, it has not been possible to draw firm conclusions. Objective: This review aims to explore the ability of MMP-9 to predict long-term prognosis of ACS. To clarify this issue, we conducted a literature review to provide a comprehensive assessment of MMP-9 levels in ACS patients. Method: We retrieved a total of 1501 articles from PubMed and Google Scholar. After thorough scrutiny, 12 original research articles were found fulfilling the inclusion exclusion criteria. MMP-9’s ability as a biomarker of prognostication post ACS was reviewed. PRISMA guidelines were used for reporting. Result: The results revealed that MMP-9, apart from being an efficient diagnostic biomarker for ACS, helps in predicting the future risk of ACS with disease outcome. Positive correlation was found between plasma MMP-9 and left ventricular remodeling. A positive association was also found between cardiovascular death and higher MMP-9 levels. Conclusion: MMP-9 can be a potential prognostic marker for ACS and aid in identifying high risk patients for intensive management during follow -up.

Background: Takotsubo Cardiomyopathy (TTC) is an uncommon cause of acute reversible ventricular systolic dysfunction in the absence of obstructive Coronary Artery Disease (CAD). Typically manifesting as apical wall ballooning, TTC can rarely present atypically with apical wall sparing. Case report: A 62-year-old female presented with complaints of chest pain and features mimicking acute coronary syndrome. Coronary angiogram revealed no obstructive CAD and left ventriculogram showed reduced ejection fraction, normal left ventricular apex and hypokinetic mid-ventricles consistent with atypical TTC. The patient was discharged home on heart failure medications and a follow-up transthoracic echocardiogram demonstrated improved left ventricular function with no wall motion abnormality. Conclusion: This case report provides an insight into the diagnosis and management of TTC in the absence of pathognomic features.

Rare Manifestation

Epilepsy is a chronic neurological disorder that is characterized by episodes of seizure. Sexual dysfunction has been reported in patients with seizure, which mostly manifests as erectile dysfunction and premature ejaculation in men. In this study, we report the case of a 65-year-old Chinese man with frequent spermatorrhea. Electroencephalography suggested local epilepsy in the left temporal lobe. After treatment with anti-epilepsy drugs, the symptoms disappeared and did not recur. To the best of our knowledge, this is the first reported case of epilepsy-induced spermatorrhea. The symptoms of spermatorrhea are probably a rare manifestation of seizure. When repetitive stereotyped symptoms occur, seizure should be considered, and tentative anti-epileptic treatment may be a good option.
