Background During COVID-19 pandemic, a lot of newly discovered symptoms and presentations are emerging. Neurological symptoms of corona virus disease 19 (COVID19) have been reported including central nervous symptoms (CNS), peripheral nervous symptoms (PNS), and skeletal muscular symptoms; however, data are scarce about the exact occurrence of neurological affection during COVID-19 infection. Case presentation We present a case of a 67-year-old male patient with proven COVID-19 infection who developed acute confusion state, behavioral changes, agitation, and one attack of loss of consciousness 8 days following the infection. Laboratory profile, computed tomography (CT) brain, magnetic resonance imaging (MRI), and cerebrospinal fluid (CSF) analysis all were normal, and the patients were highly suspicion of autoimmune encephalitis due to COVID-19 infection. The patient received pulse steroid therapy with complete regaining the conscious level. Conclusion This clinical case emphasizes the possible relationship between COVID-19 infection and autoimmune encephalitis.
Background To report a case of sudden onset left upper limb monoplegia, convulsions, and bilateral blindness in a patient receiving tacrolimus for immunosuppression following living donor liver transplantation (LDLT) consistent with posterior reversible encephalopathy syndrome (PRES). Case presentation We report a case of a 64-year-old male patient on tacrolimus treatment following LDLT. On day 11, during his post-operative routine follow-up. The patient developed sudden onset of left upper limb monoplegia associated with attacks of convulsions and sudden bilateral blindness. MRI revealed multiple, bilateral cortical, and subcortical areas of high T2 and FLAIR signal intensity that did not show restricted diffusion. Findings were suggestive of posterior reversible encephalopathy syndrome (PRES). After the cessation of tacrolimus, vision was completely regained and all other neurologic symptoms were resolved, and follow-up MRI was normal. This case represents an uncommon presentation of tacrolimus toxicity. Conclusion Tacrolimus toxicity may present with PRES. Neurological deficits may be fully reversible with discontinuation of the drug; therefore, the early recognition and prompt management of this condition are of utmost importance.
Background Elderly people are a vulnerable group of patients subjected to multiple health problems. Upper gastrointestinal bleeding (UGIB) in older adults is a frequent cause of hospital admissions. The presence of multiple comorbidities and greater medication use influence the clinical outcome. Aim The aim of our work was to analyze the etiology, precipitating factors, management, and outcome of the elderly Egyptian patients (> 65 years old) presenting with acute UGIB. Methods Three hundred thirty-two patients presenting with acute UGIB. The patients were classified into two groups according to age (elderly, above 65 years old, and young, below 65 years old). Clinical assessment, laboratory tests, and upper endoscopy were done for all patients. They were followed for 1 month. Results Elderly females showed higher incidence of acute UGIB (45.8% versus 28.9%) with significant P-value (0.001). The incidence of esophageal varices was high in young patients than in the elderly (46.4% vs 35.5%) with P-value (0.045), while the elderly patients showed a higher incidence of esophageal ulcers and gastric mass than the young patients (7.8% vs 2.4%), (6% vs 0%) with P-value (0.025 and 0.013) respectively. Also, there was a higher incidence of peptic ulcer in elderly than young patients but does not reach a significant value with P-value (0.067), while there was no difference between both groups as regards presence of (fundal varix, erosive gastritis, moniliasis, portal hypertensive gastropathy, antral gastritis, bulb duodenitis, post band ulcer, dieulafoy, gastric polyp, and angiodysplasia). Rockall score, duration of hospital stay, and mortality incidence (33.1% vs 15.7%) were high in the elderly than young patients with P-value (< 0.001). Conclusion The elderly are vulnerable groups who are at high risk of adverse outcome and mortality following acute upper gastrointestinal bleeding.
Background Hepatorenal syndrome is a potentially fatal complication of advanced liver disease. Markers for early diagnosis and identification of high-risk patients are lacking. Our aim was to evaluate the role of renal Duplex ultrasonography in the diagnosis and early prediction of hepatorenal syndrome. This study included 50 patients. Clinical assessment, liver function tests, hepatitis C virus antibody, kidney function tests, and abdominal and renal color Duplex ultrasound were done to all subjects. Results Univariate regression analysis for hepatorenal syndrome showed a statistically significant positive correlation with the Model For End-Stage Liver Disease score (p-value <0.0001) and renal artery hilum resistivity index (p-value = 0.0017). Logistic multivariable regression analysis proved that the renal artery hilum resistivity index was an independent predictor of hepatorenal syndrome. Renal artery hilum resistivity index can be used as a predictor of hepatorenal syndrome with 100% sensitivity and 66.7% specificity with a cut-off value > 0.77. Conclusion The renal resistive index could be a good predictor of hepatorenal syndrome.
BACKGROUND Pancreatic cystic lesions (PCLs) are common in clinical practice. The accurate classification and diagnosis of these lesions are crucial to avoid unnecessary treatment of benign lesions and missed opportunities for early treatment of potentially malignant lesions. AIM To evaluate the role of cyst fluid analysis of different tumor markers such as cancer antigens [ e.g. , cancer antigen (CA)19-9, CA72-4], carcinoembryonic antigen (CEA), serine protease inhibitor Kazal-type 1 (SPINK1), interleukin 1 beta (IL1-β), vascular endothelial growth factor A (VEGF-A), and prostaglandin E2 (PGE2)], amylase, and mucin stain in diagnosing pancreatic cysts and differentiating malignant from benign lesions. METHODS This study included 76 patients diagnosed with PCLs using different imaging modalities. All patients underwent endoscopic ultrasound (EUS) and EUS-fine needle aspiration (EUS-FNA) for characterization and sampling of different PCLs. RESULTS The mean age of studied patients was 47.4 ± 11.4 years, with a slight female predominance (59.2%). Mucin stain showed high statistical significance in predicting malignancy with a sensitivity of 87.1% and specificity of 95.56%. It also showed a positive predictive value and negative predictive value of 93.1% and 91.49%, respectively ( P < 0.001). We found that positive mucin stain, cyst fluid glucose, SPINK1, amylase, and CEA levels had high statistical significance ( P < 0.0001). In contrast, IL-1β, CA 72-4, VEGF-A, VEGFR2, and PGE2 did not show any statistical significance. Univariate regression analysis for prediction of malignancy in PCLs showed a statistically significant positive correlation with mural nodules, lymph nodes, cyst diameter, mucin stain, and cyst fluid CEA. Meanwhile, logistic multivariable regression analysis proved that mural nodules, mucin stain, and SPINK1 were independent predictors of malignancy in cystic pancreatic lesions. CONCLUSION EUS examination of cyst morphology with cytopathological analysis and cyst fluid analysis could improve the differentiation between malignant and benign pancreatic cysts. Also, CEA, glucose, and SPINK1 could be used as promising markers to predict malignant pancreatic cysts.
