Rationale: A novel COVID-19 is a multi-systemic critical worldwide pandemic infection. Certainly, associated multiple electrolytes imbalance in COVID-19 pneumonia is a remarkable decisive event. Camel-hump T-wave, Tee-Pee sign, and Wavy triple sign (Yasser’s sign)are novel highly significant descriptive electrocardiographic signs that are seen in calcium and potassium disturbance. There is an established and strong relationship between and electrocardiographic abnormalities and electrolytes imbalance. COVID-19 pneumonia and cerebrovascular stroke are commonly seen in a patient with Coronavirus infection. Patient concerns: A 69-year-old married worker Egyptian male patient was presented to the emergency department with COVID-19 pneumonia and cerebrovascular stroke. Diagnosis: COVID-19 pneumonia with lacunar infarction, hypocalcemia, and hyperkalemia. Interventions: Chest CT scan, brain CT scan, electrocardiography, oxygenation, and echocardiography. Outcomes: Initial bad and deterioration outcome but, the dramatic outcome had happened after later management. Lessons: The understanding of electrocardiographic signs regarding metabolic disorders such as electrolytes imbalance and other associated systemic diseases is very important. Elderly male sex, heavy smoker, COVID-19 pneumonia, cerebrovascular stroke, chronic renal impairment, ischemic heart disease, hypokalemia, hypocalcemia, and hypernatremia represent bad prognostic points and is indicating a high-risk condition.

Asterixis and dysarthria-clumsy hand are uncommon neurological signs following to movement disorders after a stroke, clinically are classified as a part of lacunar infarction and most of the cases resolved spontaneously within ten days to one month. The aim of this study was to describe the clinical characteristics of six patients with lacunar infarction and mild motor symptoms of dysarthria and asterixis with no signs of dementia. All patients had as comorbidities hypertension and/or type 2 diabetes. In conclusion, it is important due to the transience of the abnormal neurological movements, the promptly recognition of the characteristic clinical presentation and confirmation of the diagnosis with noninvasive studies. The patients should be treated to prevent recurrent stroke with more severe consequences.

This study was aimed to explore the magnetic resonance imaging (MRI) image features based on the fuzzy local information C-means clustering (FLICM) image segmentation method to analyze the risk factors of restroke in patients with lacunar infarction. In this study, based on the FLICM algorithm, the Canny edge detection algorithm and the Fourier shape descriptor were introduced to optimize the algorithm. The difference of Jaccard coefficient, Dice coefficient, peak signal-to-noise ratio (PSNR), structural similarity index measure (SSIM), running time, and segmentation accuracy of the optimized FLICM algorithm and other algorithms when the brain tissue MRI images were segmented was studied. 36 patients with lacunar infarction were selected as the research objects, and they were divided into a control group (no restroke, 20 cases) and a stroke group (restroke, 16 cases) according to whether the patients had restroke. The differences in MRI imaging characteristics of the two groups of patients were compared, and the risk factors for restroke in lacunar infarction were analyzed by logistic multivariate regression. The results showed that the Jaccard coefficient, Dice coefficient, PSNR value, and SSIM value of the optimized FLICM algorithm for segmenting brain tissue were all higher than those of other algorithms. The shortest running time was 26 s, and the highest accuracy rate was 97.86%. The proportion of patients with a history of hypertension, the proportion of patients with paraventricular white matter lesion (WML) score greater than 2 in the stroke group, the proportion of patients with a deep WML score of 2, and the average age of patients in the stroke group were much higher than those in the control group ( P < 0.05 ). Logistic multivariate regression showed that age and history of hypertension were risk factors for restroke after lacunar infarction ( P < 0.05 ). It showed that the optimized FLICM algorithm can effectively segment brain MRI images, and the risk factors for restroke in patients with lacunar infarction were age and hypertension history. This study could provide a reference for the diagnosis and prognosis of lacunar infarction.

We investigated the pathogenic relationship between cerebral microbleeds and lacunar strokes. Two cases of lacunar strokes in the region of the basal ganglia, a 72-year-old man and a 67-year-old man, were studied; both cases showed cerebral microbleeds in the stroke areas. The cerebral microbleeds were surrounded by oedema, and the oedema faded out over time, suggesting the cerebral microbleeds had developed acutely. The cerebral microbleeds were located at the ventrolateral edge of the lacunar infarctions, and the locations appeared to be at or near the sites of occlusion of the lenticulostriatal branches. Although a cerebral microbleed and a lacunar infarction may be two unrelated events on juxtapositioned vessels, or a cerebral microbleed may be haemorrhagic conversion of an infarction, a cerebral microbleed could cause an occlusion of the arterial branch, leading to lacunar infarction of its supplying territories.

Purpose: Deficiency of adenosine deaminase 2 (DADA2) is a rare autosomal recessive systemic autoinflammatory disorder. We describe a rare case of an adult patient with DADA2 who presented with unilateral frosted branch angiitis (FBA) combined with branch retinal vein occlusion and panuveitis.Method: This paper is a clinical case report.Results: A 31-year-old male patient complained of blurred vision in his right eye for 2 days. His fundus examination showed FBA combined with branch retinal vein occlusion and panuveitis. He had a medical history of intermittent and recurrent fever, skin rash and aphthous ulcer for 5 years, and lacunar infarction for 1 month. Laboratory examinations showed hypogammaglobulinemia and mild prolonged activated partial thromboplastin time (APTT). Brain magnetic resonance imaging (MRI) revealed old lacunar infarction in the right basal ganglia and the lateral ventricle and fresh lacunar infarction in the right pons, respectively. The perivascular sheathing of FBA and macular edema were resolved after steroid administration and treatment of intravitreal anti-VEGF injection. During the period of follow-up, the patient subsequently suffered from recurrence of strokes, abnormality of coagulation function, sudden hearing loss of the left ear, and diplopia. His gene sequencing results demonstrated several deletion mutations in ADA2, and the diagnosis of DADA2 was eventually confirmed.Conclusions: FBA represents a very rare ocular feature of DADA2 and may in some cases be the presenting manifestation. Therefore, ophthalmologists need to be aware of this rare autoinflammatory disease.
