In vitro screening of anti-viral and virucidal effects against SARS-CoV-2 by Hypericum perforatum and Echinacea.

Hypericum perforatum and Echinacea are reported to have antiviral activities against several viral infections. In this study, H. perforatum (St. John's Wort) and Echinacea were tested in vitro using Vero E6 cells for their anti-viral effects against the newly identified Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) through its infectious cycle from 0 to 48 h post infection. The hypericin of H. perforatum and the different parts (roots, seeds, aerial) of two types of Echinacea species (Echinacea purpurea and Echinacea angustifolia) were tested for their anti-viral activities to measure the inhibition of viral load using quantitative real-time polymerase chain reaction (qRT-PCR) on cell culture assay. Interestingly, the H. perforatum-Echinacea mixture (1:1 ratio) of H. perforatum and Echinacea was tested as well on SARS-CoV-2 and showed crucial anti-viral activity competing H. perforatum then Echinacea effects as anti-viral treatment. Therefore, the results H. perforatum and Echinacea species, applied in this study showed significant anti-viral and virucidal effects in the following order of potency: H. perforatum, H. perforatum-Echinacea mixture, and Echinacea on SARS-CoV-2 infectious cycle. Additionally, molecular simulation analysis of the compounds with essential proteins (Mpro and RdRp) of the SARS-CoV-2 revealed the most potent bioactive compounds such as Echinacin, Echinacoside, Cyanin, Cyanidin 3-(6''-alonylglucoside, Quercetin-3-O-glucuronide, Proanthocyanidins, Rutin, Kaempferol-3-O-rutinoside, and Quercetin-3-O-xyloside. Thus, based on the outcome of this study, it is demanding the setup of clinical trial with specific therapeutic protocol.

Patient-specific PEEK implants for immediate restoration of temporal fossa after maxillary reconstruction with temporalis muscle flap / 대한악안면성형재건외과학회지

Background@#Temporal hollowing is a common complication following the rotation of the temporalis muscle that leaves the patient with a cosmetic impairment. Several alloplastic materials have been used to reconstruct the donor site; however, these implants need meticulous adaptation to conform the periphery of the defect and restore the contour of the temporal area. The aim of this study was to assess the use of patient-specific polyetheretherketone (PEEK) temporal implants to prevent temporal hollowing following the use of full temporalis muscle flap for large maxillary defects reconstruction. @*Methods@#This was a prospective study conducted on eight patients with major maxillary defects indicating the need of reconstruction with full temporalis muscle flap or any lesion indicating major maxillary resection and immediate reconstruction with total temporalis muscle flap. For each patient, a patient-specific PEEK implant was fabricated using virtual planning and milled from PEEK blocks. In the surgical theater, the temporalis muscle was exposed, elevated, and transferred to the maxilla. After the temporalis muscle transfer, PEEK implants were fixed in place to prevent temporal hollowing. @*Results@#The surgical procedures were uneventful for all patients. The esthetic result was satisfactory with no post-operative complications except in one patient where seroma occurred after 2 weeks and resolved after serial aspiration. @*Conclusion@#Patient-specific PEEK implant appears to facilitate the surgical procedures eliminate several meticulous steps that are mainly based on the surgeon’s experience.

Computer-guided buccal cortical plate separation for removal of calcified benign odontogenic tumors affecting the mandibular angle region / 대한악안면성형재건외과학회지

Purpose@#Surgical removal of intra-bony calcific benign lesions is technically challenging regarding its accessibility, proximity to vital structures, and deteriorating effect on the remaining bony structures. @*Methods@#Computer-guided buccal cortical plate separation was performed for ten patients using patient-specific osteotomy locating guides and pre-bent plates. The guide was designed to outline the osteotomy, the buccal cortical plate was separated, the lesion was removed, and finally, the pre-bent plates were used to fix the separated cortex. @*Results@#Surgical procedures were uneventful for all patients, operation time was 39.5 ± 13.01 min, postoperative pain decreased within the follow-up time intervals, and there was a statistical significant difference between the time intervals (P value < 0.001). Edema and trismus were acceptable. One case showed nerve affection which resolved after 4 weeks. @*Conclusion@#Computer-guided buccal cortical plate separation for removal of intra-bony calcified benign lesions provides a promising approach, especially for inexperienced surgeons.

Full-genome sequencing and analysis of DENV-3 serotype isolated from Yemen.

BACKGROUND: Dengue virus causes the dengue fever as well as hemorrhagic fever in tropical and sub-tropical countries. It is now endemic in most parts of the South East Asia. Full-genome information of dengue virus 3 is not available from Yemen. METHODS: In this study, the dengue virus 3 was detected by diagnostic tools like serology and RT-PCR in the samples isolated from a patient in Yemen. The full-genome was sequenced, and the identity, phylogenetic relationship and recombination analysis was performed by using BioEdit, MEGA X and RDP4 softwares. RESULTS: The full-genome of the Yemen isolate was found to be 10,643 nt long with 3390 amino acids. The Yemen dengue virus 3 isolate showed the sequence similarity (98.5-92.4%) with dengue virus 3 isolates from China, Pakistan, India and Bangladesh respectively. The significant non-synonymous substitutions of amino acid in Yemen isolate were observed with selected isolates. The phylogenetic tree of Yemen isolate formed a unique clade within genotype III and sub-clade into lineage III. The Dengue virus isolate from Jeddah formed separated cluster with lineage IV. CONCLUSIONS: This reveals the unique genetic variability among DENV-3 serotypes from Jeddah and earlier reported isolates from other regions.

In vitro screening of anti-viral and virucidal effects against SARS-CoV-2 by Hypericum perforatum and Echinacea.

Special Infectious Agent Unit in King Fahd Medical Research Center at King Abdulaziz University, Jeddah, Saudi Arabia, has pursed the anti-viral project field to optimize the group of medicinal plants for human-infectious diseases. We have begun virtually in this field since COVID-19 pandemic, besides our divergence in the infectious agents. In this study and based on the previous review, Hypericum perforatum (St. Johns Wort) and Echinacea (gaia HERBS(R)) were tested in vitro using Vero E6 cells for their anti-viral effects against the newly identified Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) through its infectious cycle from 0 to 48 hours post infection. The hypericin (0.9 mg) of H. perforatum and the different parts (roots, seeds, aerial) of two types of Echinacea species (Echinacea purpurea and Echinacea angustifolia) were examined their efficacy in certain concentration and under light-dependent anti-viral activities to measure the inhibition of the SARS-CoV-2 mRNA expression of RNA-dependent RNA polymerase (RdRP) gene and the viral load with quantitative real-time polymerase chain reaction (qRT-PCR), and to assess the neutralization of the SARS-CoV-2 spike receptor binding on cell culture assay. Interestingly, the mixture (H.E.) of 100 mg/mL of H. perforatum and Echinacea was tested too on SARS-CoV-2 and showed crucial anti-viral activity competing H. perforatum then Echinacea effects as anti-viral treatment. Therefore, the results of gaia HERBS(R) products, H. perforatum and Echinacea species, applied in this study showed significant anti-viral and virucidal effects in the following order of potency: H. perforatum, H.E., and Echinacea on SARS-CoV-2 infectious cycle; and will definitely required a set up of clinical trial with specific therapeutic protocol based on the outcome of this study. Author SummaryAfter an outbreak of Rift Valley Fever in the Southern region of Saudi Arabia, particularly in May 2003, Special Infectious Agents Unit (SIAU) was established and founded by Prof. Esam Ibraheem Azhar.

In our SIAU and with a powerful team, we have excellent researches made valuable contributions through in vivo and in vitro animal and human studies, and several human viral pathogens which are a threat to global health security due to millions of pilgrims visiting Saudi Arabia every year from 182 countries: with particular areas of interests in: Alkhurma Viral Hemorrhagic Fever, Dengue Hemorrhagic Fever Viruses, Rift Valley Fever Virus, MERS-CoV and more recently the new global infectious diseases threat, Sever Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2).

Dissolved molecular hydrogen (H2) in Peritoneal Dialysis (PD) solutions preserves mesothelial cells and peritoneal membrane integrity.

BACKGROUND: Peritoneal dialysis (PD) is used as renal replacement therapy in patients with end-stage kidney disease. However, peritoneal membrane failure remains problematic and constitutes a critical cause of PD discontinuation. Recent studies have revealed the unique biological action of molecular hydrogen (H2) as an anti-oxidant, which ameliorates tissue injury. In the present study, we aimed to examine the effects of H2 on the peritoneal membrane of experimental PD rats. METHOD: Eight-week-old male Sprague-Dawley rats were divided into the following groups (n = 8-11 each) receiving different test solutions: control group (no treatment), PD group (commercially available lactate-based neutral 2.5% glucose PD solution), and H2PD group (PD solution with dissolved H2 at 400 ppb). Furthermore, the influence of iron (FeCl3: 5 µM: inducer of oxidative cellular injury) in the respective PD solutions was also examined (Fe-PD and Fe-H2PD groups). The H2PD solution was manufactured by bathing a PD bag in H2-oversaturated water created by electrolysis of the water. Twenty mL of the test solutions were intraperitoneally injected once a day for 10 days. Parietal peritoneum samples and cells collected from the peritoneal surface following treatment with trypsin were subjected to analysis. RESULTS: In the PD group as compared to controls, a mild but significant sub-mesothelial thickening was observed, with increase in the number of cells in the peritoneal surface tissue that were positive for apoptosis, proliferation and vimentin, as seen by immunostaining. There were significantly fewer of such changes in the H2PD group, in which there was a dominant presence of M2 (CD163+) macrophages in the peritoneum. The Fe-PD group showed a significant loss of mesothelial cells with sub-mesothelial thickening, these changes being ameliorated in the Fe-H2PD group. CONCLUSION: H2-dissolved PD solutions could preserve mesothelial cells and peritoneal membrane integrity in PD rats. Clinical application of H2 in PD could be a novel strategy for protection of peritoneal tissue during PD treatment.

Association of tomato leaf curl Sudan virus with leaf curl disease of tomato in Jeddah, Saudi Arabia.

Tomato is an important vegetable crop and its production is adversely affected by leaf curl disease caused by begomovirus. Leaf curl disease is a serious concern for tomato crops caused by begomovirus in Jeddah, Kingdom of Saudi Arabia. Tomato leaf curl disease has been shown to be mainly caused either by tomato leaf curl Sudan virus or tomato yellow leaf curl virus as well as tomato leaf curl Oman virus. Many tomato plants infected with monopartite begomoviruses were also found to harbor a symptom enhancing betasatellites. Here we report the association of tomato leaf curl Sudan virus causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia. The complete genome sequence analysis showed highest (99.9 %) identity with tomato leaf curl Sudan virus causing leaf curl disease in Arabian Peninsula. In phylogenetic relationships analysis, the identified virus formed closest cluster with tomato leaf curl Sudan virus. In recombination analysis study, the major parent was identified as tomato leaf curl Sudan virus. Findings of this study strongly supports the associated virus is a variant of tomato leaf curl Sudan virus causing disease in Sudan, Yemen and Arabian Peninsula. The betasatellites sequence analysis showed highest identity (99.8 %) with tomato leaf curl betasatellites-Amaranthus-Jeddah. The phylogenetic analysis result based on betasatellites formed closed cluster with tomato yellow leaf curl Oman betasatellites. The importance of these findings and occurrence of begomovirus in new geographic regions causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia are discussed.

Spontaneous bacterial empyema in a non cirrhotic end stage renal disease patient with immunosuppression.

Spontaneous Bacterial Empyema (SBEM) denotes infection of the pleural fluid in the absence of pneumonia. Almost all cases of SBEM in literature are described in a background of ascites secondary to cirrhosis. Contiguous spread of the infected ascitic fluid through defects in the diaphragm is the most likely mechanism of SBEM. Most of these cases are transudative in nature and are managed with antibiotics. Literature on SBEM in the absence of cirrhosis or ascites is very limited so far. We describe a 59 year old female with ESRD status post renal transplant, on chronic immunosuppression for renal allograft rejection who was admitted with pleuritic chest pain that turned to be secondary to right sided pleural effusion. Further evaluation revealed Escherichia coli in both the blood and pleural fluid. There was no clinical or imaging evidence of pneumonia as well as cirrhosis or ascites. She was managed as a case of SBEM requiring drainage by chest tube. Management of SBEM in non-cirrhotic individuals usually requires drainage with chest tube as against patients with liver cirrhosis with hepatic hydro-thorax in whom chest tube drainage is contraindicated for risk of massive protein and electrolyte depletion and dehydration.

Treatment of brodifacoum overdose with prothrombin complex concentrate.

PURPOSE: A case of brodifacoum overdose and its treatment with prothrombin complex concentrate (PCC) are reported. SUMMARY: A 44-year-old Caucasian woman weighing 62 kg arrived at the emergency department with a chief complaint of lower left leg pain for two days. A computed tomography (CT) scan of the abdomen revealed perihepatic fluid collection (likely a hematoma), a small-bowel intramural hematoma, and blood in the paracolic gutter. A CT scan of the patient's left foot showed soft tissue swelling without evidence of fracture or dislocation. The patient was diagnosed with left extremity compartment syndrome secondary to hematoma and trauma. The patient had a history of depression and anxiety and eventually admitted to ingesting large doses of brodifacoum the week prior with suicidal intentions. The patient was treated with phytonadione 20 mg i.v., 1 unit of fresh frozen plasma (FFP), and 1 unit of packed red blood cells. Laboratory test values measured in the intensive care unit revealed an International Normalized Ratio (INR) of 15, a prothrombin time of >120 seconds, and a partial prothromboplastin time of >180 seconds. After consulting with a local poison center, phytonadione 50 mg i.v., PCC 3100 units, and 4 units of FFP were immediately administered to reverse the patient's coagulopathy. The dose of oral phytonadione was lowered based on INR stability. Once the coagulopathy was stabilized, the patient was transferred to an inpatient psychiatric facility on phytonadione 10 mg daily orally to maintain a stable INR. CONCLUSION: A 44-year-old woman who intentionally ingested brodifacoum was successfully treated with phytonadione, PCC, and FFP.

The Role of Hemostatic Factors in Atherosclerosis in Patients with Chronic Renal Disease.

INTRODUCTION: Atherosclerotic cardiovascular disease remains the leading cause of increased morbidity and mortality observed in chronic kidney disease (CKD) patients. Endothelial dysfunction (ED) is thought to be a key initial event in the development of atherosclerosis. The aim of this study was to evaluate the potential role of hemostatic factors in atherosclerosis, thrombosis and cardiovascular complications in patients suffering from chronic renal disease. METHODS: The study was conducted on 50 renal patients divided into two groups of equal size. Group 1 consisted of 25 patients with end-stage renal disease (ESRD) on regular hemodialysis. Group 2 consisted of 25 chronic renal disease patients on conservative treatment. Twenty age- and sex-matched healthy subjects were included in the study to serve as a control group. Thrombomodulin (TM), von Willebrand factor (vWF), tissue plasminogen activator (t-PA), plasminogen activator inhibitor (PAI-1) and hsCRP were assessed. High-resolution B-mode ultrasonography of both the common and internal carotid arteries to measure carotid intima media thickness (CIMT) was performed on all subjects. RESULTS: There were highly significant increases in hsCRP, TM, vWF, tPA and PAI-1 in both patient groups compared to the control group (P<0.01 for all except for TM between group 2 and 3 P<0.05) with significant increase in group 1 compared to group 2 (P<0.01). In addition, there was a highly significant increase in CIMT in both patient groups compared to the control group (P<0.01) with a significant increase in group 1 compared to group 2 (P<0.05). The study revealed significant positive correlation of hemostatic factors (TM, vWf, PAI-1 & t-PA) with creatinine, urea, hsCRP & CIMT. CONCLUSION: CKD patients have increased risk of atherosclerosis as measured by CIMT, which is used as a surrogate marker of early atherosclerosis and has been shown to be a strong predictor of future myocardial infarction and stroke. They have high levels of TM, vWF, tPA, PAI-1 that correlate with kidney function, hsCRP and CIMT. Therefore, these abnormalities in hemostasis may account for the increased risk of atherothrombosis in these patients. The elevated hsCRP levels and their correlation to hemostatic factors and CIMT might provide an important clue to link a systemic marker of inflammation to atherosclerosis. Further research is required to better understand the procoagulant state in patients with CKD.

Noncompaction Cardiomyopathy with Charcot-Marie-Tooth Disease.

We report a case of a 53-year-old female presenting with a new-onset heart failure that was contributed secondary to noncompaction cardiomyopathy. The diagnosis was made by echocardiogram and confirmed by cardiac MRI. Noncompaction cardiomyopathy (also known as ventricular hypertrabeculation) is a newly discovered disease. It is considered to be congenital (genetic) cardiomyopathy. It is usually associated with genetic disorders and that could explain the genetic pathogenesis of the non-compaction cardiomyopathy. Our case had a history of Charcot-Marie-Tooth disease. There is a high incidence of arrhythmia and embolic complications. The treatment usually consists of the medical management, defibrillator placement, and lifelong anticoagulation. Heart transplantation will be the last resort.

Exfoliative erythroderma as a paraneoplastic presentation of adenocarcinoma of the gallbladder.

We report a case of a 71-year-old Caucasian male presenting with an exfoliative skin rash all over his body. The patient was also found to have a huge gall bladder mass extending into the liver that turned out to be adenocarcinoma of the gall bladder on biopsy. Gall bladder cancer usually presents with abdominal pain, swelling or jaundice. We report only the second case in literature of a gall bladder adenocarcinoma presenting with exfoliative erythroderma as its paraneoplastic presentation.

Complete heart block with diastolic heart failure and pulmonary edema secondary to enlarging previously diagnosed thrombosed aneurysm of sinus of valsalva in a patient with history of autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is associated with vascular aneurysms that can affect any part of the vascular tree, like ascending aorta or coronary arteries. Sinus of Valsalva is known as an anatomical dilation at the root of aorta above the aortic valve and very few cases show aneurysm at that site in patients with ADPKD. Sinus of Valsalva aneurysm (SVA) can present with rupture and acute heart failure and infective endocarditis or could be asymptomatic accidentally discovered during cardiac catheterization. We report a case of a 76-year-old male with a unique constellation of cardiovascular anomalies associated with ADPKD. Patient was previously diagnosed with aneurysms affecting ascending aorta, sinus of Valsalva, and coronary arteries. Several years later, he came with complete heart block which was discovered later to be secondary to enlargement of his previously diagnosed thrombosed SVA. His case was complicated with acute heart failure and pulmonary edema. Conclusion. Patients with ADPKD can present with extrarenal manifestations. In our case, aneurysm at sinus of Valsalva was progressively enlarging and presented with complete heart block.

Mediastinal B-cell lymphoma presenting with jugular-subclavian deep vein thrombosis as the first presentation.

Jugular venous thrombosis infrequently could be secondary to malignancy and has seldom been reported secondary to mediastinal large B-cell lymphomas. The postulated mechanisms are mechanical compression that leads to stagnation of blood in the venous system of the neck and/or an increase in the circulating thrombogenic elements that could cause venous thromboembolism as a paraneoplastic phenomenon. We report the case of a middle aged male presenting with right sided neck pain and arm swelling secondary to ipsilateral jugular-subclavian deep vein thrombosis. Investigations revealed it to be secondary to a mediastinal mass shown on CT scan of the chest.

Multi-organ failure secondary to a Clostridium perfringens gaseous liver abscess following a self-limited episode of acute gastroenteritis.

BACKGROUND: Clostridium perfringens is an unusual pathogen responsible for the development of a gas-forming pyogenic liver abscess. Progression to septicemia with this infection has amplified case fatality rates. CASE REPORT: We report a case of an 81-year-old lady with pyogenic liver abscess with gas formation that was preceded by an acute gastroenteritis. The most common precipitating factors are invasive procedures and immunosuppression. Clostridium perfringens was unexpectedly isolated in the drained abscess, as well as blood. It is a normal inhabitant of the human bowel and a common cause of food poisoning, notoriously leading to tissue necrosis and gas gangrene. CONCLUSIONS: We report a case of gas-forming pyogenic liver abscess and bacteremia progressing to fatal septic shock, caused by an uncommon Clostridium perfringens isolate.

Metastatic malignant melanoma of the inguinal lymph node with unknown primary lesion.

Background. Malignant melanoma could present with metastasis with unknown primary (MUP) and this happens in 2-3% according to the studies. Around 90% of melanomas have cutaneous origin, but still there are melanomas that could be found in visceral organs or lymph nodes with unknown primary site. Spontaneous regression of the primary site could be an explanation. Case Report. We report a 58-year-old Caucasian male who presented with a right sided swelling in the inguinal region. Surgery was performed and biopsy showed metastatic malignant melanoma. No cutaneous lesions were identified by history or physical examination. Work up could not detect the primary lesion and patient was started on radiotherapy and immunotherapy. Conclusion. We present a case of malignant melanoma of unknown primary presenting in an unusual place which is the inguinal lymph node. Theories try to explain the pathway of development of such tumors and one of the theories mentions that it could be a spontaneous regression of the primary cutaneous lesion. Another theory is that it could be from transformation of aberrant melanocyte within the lymph node. Prognosis is postulated to be better in this case than in melanoma with a known primary.

Dieulafoy lesion in the ascending colon presenting with gastrointestinal bleeding and severe anemia complicated by a coexisting severe resistant chronic idiopathic thrombocytopenic purpura.

Background. GI (gastrointestinal) bleeding can be due to a variety of etiologies ranging from being common like bleeding peptic ulcer disease or esophageal varices. One of the rarely documented causes is the Dieulafoy lesion which is known as an abnormally large ectatic artery that penetrates the gut wall, occasionally eroding through the mucosa causing massive bleeding. In addition to that, we refer to the uncommon presentation of Dieulafoy lesion itself as it is well known to be found in the stomach, esophagus, duodenum, and jejunum but not the ascending colon as in our case. The patient had a coexisting ITP (idiopathic thrombocytopenic purpura) that was resistant to different therapies. Case Report. We report a case of a 48-year-old Egyptian female known for chronic ITP resistant to treatment. The patient presented with bright red bleeding per rectum and severe life threatening anemia. Endoscopic study showed a Dieulafoy lesion. Endoscopic clipping was successful in controlling the bleeding. Conclusion. Dieulafoy lesion is a rare reason for GI bleeding and can present in common or unexpected places. Also extreme caution should be used in patients with bleeding tendency due to different reasons, like ITP in our case.

Recurrent sinus pauses: an atypical presentation of temporal lobe epilepsy.

Autonomic dysfunction related to seizures may give rise to a broad spectrum of cardiovascular abnormalities. Among these, ictal bradycardia and conduction delays may be encountered. Failure to recognize these abnormalities may contribute to sudden, unexplained death in epilepsy patients. We report a case of a Haitian female with temporal lobe epilepsy associated with recurrent sinus pauses.

A pathologist's survey on the reporting of sessile serrated adenomas/polyps.

AIM: The purpose of this survey was to ascertain reporting habits of pathologists towards sessile serrated adenomas/polyps (SSA/P). METHODS: A questionnaire designed to highlight diagnostic criteria, approach and clinical implications of SSA/P was circulated electronically to 45 pathologists in the UK and North America. RESULTS: Forty-three of 45 pathologists agreed to participate. The vast majority (88%) had a special interest in gastrointestinal (GI) pathology, had great exposure to GI polyps in general with 40% diagnosing SSA/P at least once a week if not more, abnormal architecture was thought by all participants to be histologically diagnostic, and 11% would make the diagnosis if a single diagnostic histological feature was present in one crypt only, while a further 19% would diagnose SSA/P in one crypt if more than one diagnostic feature was present. The vast majority agreed that deeper sections were useful and 88% did not feel proliferation markers were useful. More than one-third did not know whether, or did not feel that, their clinicians were aware of the implications of SSA/P. CONCLUSIONS: 98% of pathologists surveyed are aware that SSA/P is a precursor lesion to colorectal cancer, the majority agree on diagnostic criteria, and a significant number feel that there needs to be greater communication and awareness among pathologists and gastroenterologists about SSA/P.

Acute renal infarction presenting with acute abdominal pain secondary to newly discovered atrial fibrillation: a case report and literature review.

We report an 85-year-old female with known history of recurrent diverticulitis presented with abdominal pain. It was believed that the patient again needed to be treated for another diverticulitis and was started on the routine treatment. The initial CT scan of abdomen showed renal infarcts bilaterally that were confirmed by a CT with and without intravenous contrast secondary to unknown cause. An ECG found accidentally that the patient was in atrial fibrillation, which was the attributed factor to the renal infarctions. Subsequently, the patient was started on the appropriate anticoagulation and discharged.
