Coronavirus in patient with positive PCR test in cerebrospinal fluid led to generalized tonic-clonic seizure without brain lesion: a case report

SARS-CoV-2 which first was observed in Wuhan region, China in December 2019 is affected many organs, such as central nervous system. We describe a case of a 57-year-old male patient, in hospital with the loss of consciousness, in the form of lack of verbal and visual communication. He got a seizure attack for about 3 minutes in the form of generalized tonic-clonic seizure (GTS) and admitted to the neurological department and was intubated. Since, the patient was not aware, awake, did not obey, corneal reflexes test was positive and his pupils were isochoric and reactive therefore, the primary diagnosis was cerebrovascular accident (CVA). On the second day after admission, although the brain computed tomography (CT) did not show brain lesion, but chest X-ray (CXR) revealed lung involvement. In addition, on third day the RT-PCR test for coronavirus RNA in and the cerebrospinal fluid and nasopharyngeal swap done and the result was positive for both of them. Therefore, treatment for the covid-19 was started. Result(s): Since, the treatment for the covid-19 was started with Atazanavir, Clindamycin and ceftriaxone, ten days after hospitalization, the lung involvement and general condition of patient got better and after two weeks he was released from the hospital. Conclusion(s): GTS should be considered as a neurological outcome of COVID-19 and medications against the coronavirus, such as Atazanavir, Clindamycin and ceftriaxone can recover the neurological deficits in these patients.Copyright© 2020, TMU Press.

Cool Your Jets Bro

History: Twenty-two year old male basic trainee was brought to the ED after collapsing during a routine ruck march. At mile 8/12, soldier was noted to develop an unsteady gate and had witnessed loss of consciousness. A rectal core temperature was obtained and noted to be >107degreeF. Cooling initiated with ice sheets and EMS was activated. On arrival to the ED, patient demonstrated confusion and persistently elevated core temperatures despite ice sheeting, chilled saline and cold water bladder lavage. Cooling measures were discontinued after patient achieved euthermia in the ED;however, his temperatures subsequently spiked>103degreeF. Given rebound hyperthermia, an endovascular cooling (EVC) device was placed in the right femoral vein and patient was transferred to the ICU. Multiple attempts to place EVC device on standby were unsuccessful with subsequent rebound hyperthermia. Prolonged cooling was required. Physical Exam: VS: HR 121, BP 85/68, RR 22 SpO2 100% RA, Temp 102.4degreeF Gen: young adult male, NAD, shivering, A&Ox2 (person and place only) HEENT: Scleral anicteric, conjunctiva non-injected, moist mucus membranes Neck: Supple, no LAD Chest: CTAB, no wheezes/rales/rhonchi CV: tachycardia, regular rhythm, normal S1, S2 without murmurs, rubs, gallops ABD: NABS, soft/non-distended, no guarding or rebound EXT: No LE edema, tenderness SKIN: blisters with broad erythematous bases on bilateral heels Neuro: CN II-XII grossly intact, 5/5 strength in all extremities. Differential Diagnosis: 216. Septic Shock 217. Hypothalamic Stroke 218. Exertional Heat Stroke (EHS) 219. Neuroleptic Malignant Syndrome 220. Thyroid Storm Test Results: CBC: 18.2>14.5/40.6<167 CMP: 128/3.5 88/1831/2.7<104, AST 264, ALT 80, Ca 8.8 Lactate: 7.1 CK: 11 460 Myoglobin: 18 017 TSH: 3.16 CXR: No acute cardiopulmonary process Blood Cx: negative x2 CSF Cx: Negative COVID/Influenza/EBV: Negative Brain MRI: wnl. Final Diagnosis: Exertional Heat Stroke. Discussion(s): No EVC protocols exist for the management of EHS or rebound/refractory hyperthermia. As a result, the protocol used for this patient was adapted from post-cardiac arrest cooling protocols. It is unclear if this adapted protocol contributed to his delayed cooling and rebound hyperthermia as it was not intended for this patient demographic/ pathophysiology. Furthermore, despite initiating empiric antibiotics upon admission, delayed recognition and tailored therapy for his bilateral ankle cellulitis may have contributed to the difficulty in achieving euthermia. In summary, more research needs to be done to evaluate and develop an EVC protocol for EHS. Outcome(s): Euthermia was achieved and maintained after 36 hours of continuous EVC, at which point it was discontinued. His CK, AST/ALT, creatinine and sodium down-trended after discontinuation of EVC. Patient's antibiotics were transitioned to an oral formulation for treatment of ankle cellulitis and he was prepared for discharge. He was discharged with regular follow-up with the Fort Benning Heat Clinic. Follow-Up: After discharge, patient had regularly scheduled visits with the Fort Benning Heat Clinic. His typical lab markers for exertional heat stroke were regularly monitored. He had continued resolution of his Rhabdomyolysis, acute kidney injury and hyponatremia with typical treatment. Soldier returned to duty after 10 weeks of close monitoring and rehabilitation.

Occlusive Explosion

Clinical Information Patient Initials or Identifier Number: A Relevant Clinical History and Physical Exam: 47yr old man, suffered a blast injury at the workplace after an O2 tank exploded while he was transferring liquid gas into a tank for welding purposes. The impact has caused him to temporary loss of consciousness. Upon awakening, he had severe chest pain associated with shortness of breath. On examination, superficial partial thickness injury on the chest wall, and lungs: reduced breath sound bi-basally, no murmur heard. BP:106/77mmHg, HR:100/min, SPO2 100% on HFM 15L/min. [Formula presented] [Formula presented] [Formula presented] Relevant Test Results Prior to Catheterization: Serial ECGs were done and showed dynamic changes in the anterior leads Bedside echo before invasive coronary angiograms shows mild LVSD, normal valves, and no pericardial effusion [Formula presented] [Formula presented] Relevant Catheterization Findings: Right radial approach 6F system Opitorque catheter for diagnostic angiogram LMS: smooth LAD: ATO mid LAD, DG1 prox ATO LCx: smooth RCA: smooth Impression: ATO to LAD and Diagonal 1 ( Dual ATO) [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: Right radial coronary angiogram via 6F system EBU 3.0 engaged with good support Sion blue wired into LAD, export catheter delivered, and aspirated red thrombus Pre-dilated with Sapphire 3 SC 2.5x15mm @ 6-10ATM Flow established in LAD, however, decided to interrogate DG1 as it shows ATO BMW wired into the DG1 and pre-dilated with Sapphire 3 SC 2.0x15mm Noted nonflow limiting dissection and decided to stent DG1 with 2.25x34mm@12ATM, dissection sealed and TIMI III flow established Stented mid LAD with 2.5x30mm @12ATM just before LAD/DG1 bifurcation, then stented proximal LAD with 2.5x 26mm@ 12ATM. Post-dilated LAD with 2.75x15mm@ 14-20ATM TIMI II-III flow IV Tirofiban has been given a loading dose due to a high thrombus burden and sluggish flow [Formula presented] [Formula presented] [Formula presented] Conclusion(s): Myocardial infarction is a rare complication of blunt chest trauma. This case demonstrates how blast shock waves result in the dissection of the coronary vessel leading to total occlusion of the two vessels. It also promotes red thrombus within the coronary vessels. Percutaneous coronary intervention is the most suitable way to treat this condition. Intravascular imaging such as IVUS or OCT would be beneficial to demonstrate the physiology behind this MI and would also be helpful in planning and optimizing the lesions. Unfortunately, intravascular imaging was not used for this patient to reduce procedural time as he was treated during the height of the COVID pandemic.Copyright © 2023

Why Does It Feel Different? Provider Moral Distress in Removing Unwanted Aggressive Intervention for Conscious Patients (TH123B)

Outcomes: 1. Illustrate increased moral distress associated with removing unwanted aggressive interventions for conscious patients compared to unconscious patients. 2. Demonstrate the importance of the interdisciplinary team in supporting providers experiencing moral distress. When providing end-of-life care, removing unwanted aggressive intervention is more challenging in a conscious patient. If the intent to provide comfort and reduce suffering is the same, why does it feel different when the patient is conscious? This case examines the moral distress experienced by the palliative care team who assisted a conscious patient with Duchenne muscular dystrophy achieve his goal of liberation from the ventilator. A 41-year-old male with Duchenne muscular dystrophy and prior COVID-19 infection presented with respiratory failure. The patient had COVID-19 infection in April 2022 and was ventilator dependent since then. The palliative care team was consulted for goals of care discussion. After extensive discussion with the patient and his family, the patient decided to be disconnected from the ventilator and wanted a peaceful passing because long-term ventilatory support was no longer acceptable to him. He was afraid of being aware of struggling to breathe and requested to be asleep throughout this process. Specifically, he said he wanted "to close my eyes and see [my family] on the other side." When the patient was comfortable and asleep as he and his family desired, he was disconnected from the ventilator and died peacefully with his family around him. During this process, the palliative care team's intent was clear: follow the patient's wishes and provide comfort. Ethically, there is no difference in removing unwanted aggressive interventions between conscious and unconscious patients, but the team experienced significantly more distress in this case. After the patient's death, the interdisciplinary team provided support to help the palliative care team work through the distress experienced.Copyright © 2023

Covid-19 Vaccine safety and adverse event analysis from Pakistan

Covid immunization commenced on 2nd Feb 2021 in Pakistan and as of 7th Sep 2021, over 84 million vaccine doses were administered in Pakistan, of which 72% procured by the government, 22% received through Covax and 6% were donated. The vaccines rolled out nationally included: Sinopharm, Sinovac and CanSinoBIO (China), AstraZeneca (UK), Moderna and Pfizer (USA), Sputnik (Russia), and PakVac (China/Pakistan). About half of the eligible population in Pakistan (63 m) had received at least one dose of Covid vaccine as of Sep 2021. Pakistan National Pharmacovigilance Centre (PNPC) in coordination with WHO, MHRA and Uppsala Monitoring Centre (UMC) established pharmacovigilance centers across Pakistan. The Covid vaccine AEFIs in Pakistan were mainly reported via NIMS (National Immunization Management System), COVIM (Covid-19 Vaccine Inventory Management System), 1166 freephone helpline and MedSafety. There have been 39,291 ADRs reported as of 30th Sept 2021, where most reported after the first dose (n = 27,108) and within 24-72 h of immunization (n = 27,591). Fever or shivering accounted for most AEFI (35%) followed by injection-site pain or redness (28%), headache (26%), nausea/vomiting (4%), and diarrhoea (3%). 24 serious AEFIs were also reported and investigated in detail by the National AEFI review committee. The rate of AEFIs reports ranged from 0.27 to 0.79 per 1000 for various Covid vaccines in Pakistan that was significantly lower than the rates in UK (~4 per 1000), primarily atrributed to underreporting of cases in Pakistan. Finally, Covid vaccines were well tolerated and no significant cause for concern was flagged up in Pakistan's Covid vaccine surveillance system concluding overall benefits outweighed risks.Copyright © 2022

Aseptic meningitis caused by Coronavirus OC43 in a child: A case report

Human coronavirus OC43 (HCoV-OC43) is one of the coronaviruses that cause the mild cold. On the other hand, extra-respiratory manifestations such as central nervous system infections with HCoV-OC43 are very rarely reported. We present a case of a previously healthy immunocompetent child with acute aseptic meningitis, as a result of HCoV-OC43 who admitted to the emergency department with a complaint of unconsciousness.. Respiratory tract and cerebrospinal fluid culture showed HCoV-OC43 in viral screening. During the follow-up period, the patient was completely asymptomatic, with normalized consciousness. The clinicians should keep in mind that HCoV-OC43 can be the etiological agent in the differential diagnosis of aseptic meningitis in immunocompetent individuals with reversible neurological symptoms.Copyright © 2022, Derman Medical Publishing.

A fall in isolation: reflection on a complex case

This case review focuses on a male patient who had fallen and was found to be profoundly hypothermic, with an altered level of consciousness and evidence of seizure activity. With multiple time-critical features, this clinical presentation was made particularly challenging by the presence of several human factors. A reflective model that considered these human factors in the context of the COVID-19 pandemic, when this incident occurred, was employed. Reflecting on this incident revealed how some subconscious (intuitive) thinking led to a degree of unconscious bias compounded by availability heuristics and human factors present. This meant that the author encountered difficulty when trying to obtain peripheral vascular access and, although several alternative interventions were identified, the majority of these were unavailable at the time and some would require a change to standard clinical practice for many paramedics. The only intervention that could have been used earlier in the management of this patient was rectal diazepam, but the need for this was removed by the patient's seizure activity self-terminating. Given the increasing prevalence of falls, social isolation, mental health problems, alcohol and substance misuse, especially in the pandemic, this type of case was unlikely to be an isolated event, strengthening the argument that the range of clinical interventions available to paramedics should be increased.

Tocilizumab- a Treatment Option for Torsades De Pointes in Covid-19 Patients

Background The incidence of ventricular arrhythmias (VA) in Coronavirus disease 2019 (COVID-19) patients ranges from 1.6 to 5.9%. COVID-19 can trigger a systemic inflammatory response, which may unmask arrhythmias. Here we discuss a challenging case of COVID-19 that manifested as recurrent Torsades de Pointes (TdP). Case A 39-year-old female with no known past medical history presented with a complaint of multiple syncopal episodes in the last two days. Initial electrocardiograms (EKG) showed a heart rate of 62 with frequent premature ventricular contractions (PVCs) and a prolonged corrected QT(QTc) interval of 520ms. Frequent PVCs soon converted to TdP with loss of consciousness which was managed with successful direct current cardioversion (DCCV). However, the patient relapsed into TdP, warranting another successful DCCV. COVID-19 workup came back positive. Electrolytes were within normal limits;however, C-reactive protein (CRP) and troponin T levels were elevated. Decision-making The patient was started on intravenous (IV) magnesium for 24 hours. Following another episode of self-limiting TdP, IV isoproterenol was started, and tocilizumab was given. An echocardiogram showed no evidence of structural heart disease. During the hospital course, telemetry showed PVCs that decreased in frequency paralleled with a decrease in CRP and troponins. Repeat EKGs showed normalization of QTc interval. The patient declined implantable device placement or procedures and was eventually discharged with a heart monitor and a beta blocker. On follow-up, the patient denied any symptoms since the discharge, QTc remained normal, and the heart monitor did not show any VA. Conclusion Management of TdP generally involves magnesium, IV isoproterenol, and transvenous pacing. However, as described in this case, tocilizumab can cause QT interval shortening and a reduction in CRP and cytokine levels and may be beneficial for use in COVID-19 patients with QT prolongation and VA, including TdP. There are no strict guidelines for arrhythmias in COVID-19 patients. Accordingly, more studies need to be done to follow this patient population managed with tocilizumab for their eventual outcomes.Copyright © 2023 American College of Cardiology Foundation

Comorbidities and Mortality Risk in COVID-19 Infected Patients: A Cross-Sectional Study in North-Eastern Iran

Objective: The coronavirus disease-2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2, started in Wuhan, China, and was recognized as a pandemic by the World Health Organization. In Iran, the first confirmed COVID-19 case was officially reported on February 19. The aim of this study was to investigate the epidemiological and clinical characteristics, and comorbid conditions, and determine risk factors for the mortality of COVID-19 patients as well as provide a comparison of the epidemiological features between the 3 waves of COVID-19 in the North-East of Iran from January 21, 2020, to March 20, 2021. Material(s) and Method(s): The current retrospective epidemiological population-based study was conducted on COVID-19 patients who were admitted to the hospitals affiliated to the Mashhad University of Medical Sciences in Razavi-Khorasan province, Iran. The data were extracted from the Medical Care Monitoring System of the Mashhad University of Medical Sciences. Result(s): In total, 43.6% of subjects had at least one coexisting underlying medical condition. The most common comorbidities were hypertension, diabetes, and cardiovascular diseases with the prevalence of 19.7, 15.1, and 13.3%;respectively. The overall case fatality rate was 15.0%, following a median of 4 days [interquartile range (IQR) 1-10] of hospitalization. The mean+/-SD and the median (IQR) of age in expired subjects were 67.40+/-18.27 and 70 (59-81) years;respectively. Conclusion(s): Our results demonstrated that age >60, male sex, loss of consciousness, respiratory distress, having at least one comorbidity, and diabetes were mortality risk factors among COVID-19 patients.Copyright © 2023 by Turkiye Klinikleri.

Mineralizing angiopathy: an underrecognized clinicoradiologic entity

Case Report: Initial History/Presentation: A term vaccinated 7-month-old male with a history of eczema presents with two hours of right-sided hemiplegia and hemidystonia. Parents deny loss of consciousness, altered mental status, or facial symptoms. He has no known history of recent or remote head trauma. Patient may have had COVID two months prior when he had upper respiratory symptoms, with his mother testing COVID+ at that time. Of note, he received a Moderna COVID vaccination one day prior to onset of symptoms. Physical Exam: Pertinent exam findings include CN II-XII intact, right-sided upper and lower extremity strength 3/5, sensation intact, and truncal ataxia while seated. Physical exam is otherwise unremarkable. Diagnostic Evaluation: Initial lab work revealed leukocytosis (20.9), but otherwise a reassuring CMP, triglycerides, HDL, and LDL. PTT was elevated, but normal on recheck. Protein C antigen and activity were low, but deemed non-concerning by hematology. All other hypercoagulable labs were normal. On imaging, CT Brain showed linear calcifications in bilateral basal ganglia suggestive of mineralizing angiopathy. HisCTA head/neckwas negative.MRI Brain revealed an acute infarct of the body/tail of the left caudate nucleus, posterior limb of internal capsule, and posterior putamen. Clinical Course/Follow-up: Our patient was started on Aspirin 4 mg/kg daily. Throughout the course of his 3-day inpatient stay, he had mild improvement of right-sided strength and function, and continued improvement upon follow-up with his pediatrician. Given the short interval between receiving his COVID vaccination and onset of symptoms, his case was reported to the Vaccine Adverse Event Reporting System. Conclusion(s): From a radiological perspective, mineralizing angiopathy is an uncommon but familiar finding seen in up to 5% of all neonatal head ultrasounds and increasing to nearly 20% in preterm infants. It is most commonly associated with infection, hypoxia, and chromosomal abnormalities but is usually of minimal clinical significance. However, there are numerous reports of basal ganglia and thalamic strokes following minor head trauma in children with mineralizing angiopathy. For radiologists, this association is important to recognize and relay to the primary team so targeted history and MRI, if indicated, may be obtained to expedite definitive diagnosis and initiation of treatment to preserve precious brain tissue. Without a history of head trauma, in this case, stroke provocation is unclear, and other infectious or inflammatory disorders could appear similarly if they induced vasospasm or blood pressure lability. A short-interval timeframe between COVID vaccine administration and symptom onset is likely incidental, but research to exclude or illicit any link may be of benefit. Findings of mineralizing angiopathy on CT in the appropriate clinical setting should prompt further evaluation with emergent MRI to determine the presence of basal ganglia or thalamic stroke.

Severe, Progressive Meningoencephalitis in a Patient with Coexisting SARS-CoV-2 and Cytomegalovirus Infection: A Case Report

SARS-CoV-2, the pathogen responsible for COVID-19, has infected hundreds of millions since its emergence in late December 2019. Recently, concern has been raised due to the increased prevalence of co-infections with opportunistic pathogens among these pa-tients. Though not common, co-infections may be associated with adverse outcomes and increased risk of morbidity and mortality among patients suffering from COVID-19. Cytomegalovirus (CMV) infection is a serious problem among immunocompromised and critically ill patients. So far, few cases of co-infection with COVID-19 and CMV have been reported. Here, we report the co-infection with COVID-19 and CMV in a young woman presenting with sudden, progressive fever, delusion, agitation, bizarre behavior, seizure, and loss of consciousness leading to death despite receiving appropriate anti-viral treatment. To the best of our knowledge, this is the first case of coexisting SARS-CoV-2 and CMV infection presenting with severe, progressive meningoencephalitis in the era of COVID-19.

Severe progression of autoimmune hepatitis in a young COVID-19 adult patient: A case report

Rationale: The impact of COVID-19 in patients with autoimmune liver disease treated with immunosuppressive therapy has not been described so far. This case report describes the clinical course of a patient with autoimmune hepatitis (AIH) who developed COVID-19 and the features of cytokine syndrome leading to its deterioration in our intensive care unit. Patient's Concern: A 28-year-old male presented with generalized anasarca for two weeks and chronic liver disease for 8 months. Diagnosis: AIH and Covid-19 with features of cytokine storm syndrome. Interventions: Intravenous furosemide, mannitol, syrup lactulose, steroids (prednisolone 40 mg), azathioprine 1 mg/kg body weight, rifaximin, vitamin K, and blood products. Outcomes: The patient had hepatic encephalopathy and AIH and died on the 10th day after admission despite ventilatory support, sustained low-efficiency hemodialysis, and resuscition. Lessons: The dramatic release of cytokines and the inflammatory-immune responses not only alter the pathophysiology but also affects the onset and severity of disease progression in patients with AIH.

Surgical Management of Rhino-Orbito-Cerebral Mucormycosis Post-COVID-19 Infection

Introduction: The pandemic of COVID-19 in association with mucormycosis would be a deadly fungal infection with high level of mortality and morbidity. Our aim is to evaluate the surgical outcome of patients with rhino-orbito-cerebral mucormycosis to suggest better management strategies. Method(s): A total of 62 cases of COVID-19-associated rhino-orbito-cerebral mucormycosis were admitted to the ear, nose, throat department in Mashhad, Iran, from August 1 to October 15, 2021. All data were analyzed using SPSS version 27.0. Descriptive analysis was used for demographic and clinical characteristics. Result(s): Main predisposing conditions were diabetes mellitus (90%) followed by hypertension (41%). Main symptoms were headache (75%), periorbital or retro-orbital pain (61%), visual loss (45%), and facial numbness (41%). Mucosal and ocular findings showed necrosis (67%), blindness (n=35), ptosis (n=31), proptosis (n=27), ophthalmoplegia (n=25), and chemosis (n=20). Neurologic loss of consciousness (19%) and palsies of cranial nerves (53%) were observed. Endoscopy findings showed necrosis (70%), discharge (61%), and crusting (54%). Imaging enhancement revealed mucosal thickening (69%), opacification of sinus (69%), bony destruction of sinus (35%), and orbital involvement (25%). Debridement surgery was necessary in nearly all patients (96%), dominated by ethmoid sinus (90%), maxillary sinus (87%), middle turbinate (80%), and sphenoid sinus (79%). Based on our follow-up, 25 patients died (42%). Those who survived will suffer from no light perception (35%), cranial nerve palsy (12%), and cerebral vascular accident (1.6%). Conclusion(s): Mucormycosis is an aggressive fungal infection. Diabetes mellitus, COVID-19 complication, inappropriate use of corticosteroids, and delayed vaccination had significantly increased its incidence. As there is an urgent need to address this public health concern, we present our data set from Iran.

A CASE OF TRACHEOBRONCHIAL AMYLOIDOSIS PRESENTING AS SYNCOPE

SESSION TITLE: Systemic Diseases with Deceptive Pulmonary Manifestations SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/18/2022 12:25 pm - 01:25 pm INTRODUCTION: Amyloidosis of the respiratory tract is rare. We present a case of tracheobronchial amyloid presenting as multifactorial cough with syncope. CASE PRESENTATION: The patient is a 65-year-old man with history of hypertension, hyperlipidemia, and allergic rhinitis who presented to the ED after a syncopal event. Two weeks prior, he had a new-onset myalgias and severe persistent cough, not resolving with over-the-counter medications. During a coughing paroxysm, he experienced a brief loss of consciousness. On arrival, his vital signs and physical exam were within normal limits except for Mallampati II, BM of 38.8 kg/m2. Basic laboratory testing was also unremarkable except for troponin T of 251 nl/dL and NT-ProBNP of 1181 pg/mL. NP swab for Sars-CoV-19 (PCR), Influenza A and B were not detected. CT of the chest revealed an area of circumferential mural soft tissue thickening in the left lower lobe bronchi. Cardiac MRI showed an area of subepicardial delayed enhancement, suggestive of myocardial inflammation or edema. Flexible bronchoscopy confirmed that the left lower lobe bronchus and proximal subsegmental bronchi had an infiltrative process with a friable, erythematous irregular mucosal surface. Forceps biopsy sampling and staining with Congo red, sulfate Alcian blue and Trichome stain were positive for amyloid deposits. Immunostain revealed predominantly CD3 positive T-Cells. Mass spectometry showed AL (lamda)-type amyloid deposition. GMS and AFB stains were negative. Telemetry showed 2-3 second pauses, correlated with episodes of cough. DISCUSSION: Amyloidosis is a disorder caused by misfolding of proteins and fibril accumulation in the extracellular space. It can present as a diffuse or localized process to one organ system. Several patterns of lung involvement have been described: nodular pulmonary, diffuse alveolar-septal, cystic, pleural, and tracheobronchial amyloidosis. Tracheobronchial amyloidosis is usually limited and not associated with systemic disease or hematologic malignancy. It can be asymptomatic, or can present with cough, dyspnea or signs of obstruction, including postobstructive pneumonia. Congo Red stained samples reveal green birefringence under polarized light microscopy. Further analysis of proteins usually reveals localized immunoglobulin light chains (AL). Cough syncope is due to increased intrathoracic pressure, decreased venous return and cardiac output, stimulation of baroreceptors, decreased chronotropic response, arterial hypotension and decreased cerebral perfusion. Our patient presented with multifactorial cough (possible viral infection, upper airway cough syndrome, amyloidosis) causing sinus pauses and syncope, on underlying myocarditis. CONCLUSIONS: Amyloid infiltration of the respiratory system is rare, but it should be considered in the differential diagnosis of airway disorders, nodular or cystic lung diseases, and pleural processes.

Clinical characteristics of 365 hospitalized COVID-19 patients with neurological symptoms: an observational study.

OBJECTIVE: Since the beginning of the COVID-19 pandemic, a number of COVID-related neurological manifestations have been reported. We aimed to categorize the features of hospitalized COVID-19 patients who experienced neurological symptoms. METHODS: In this descriptive, cross-sectional study, we enrolled all patients hospitalized with COVID-19 who experienced neurological symptoms in two hospitals in Tehran. Diagnosis of COVID-19 was established by PCR tests or computed tomography of the chest combined with COVID-19 clinical findings. The clinical characteristics, laboratory data, and imaging findings from 365 patients were analyzed. RESULTS: The average patient age was 59.2 ± 16.7 years and included 213 males and 152 females. The most prevalent neurological symptoms were headache (56.2%), impaired consciousness (55%), and dizziness (20.5%). During hospitalization, most of the patients did not require mechanical ventilation (81.9%). The percentage of patients with end-organ damage was 9% and mortality was 15%. Regression analysis on the neurological symptoms indicated that the mortality rate of patients with headaches was 84% lower than for the other neurological symptoms. Hyperglycemia was significantly related with end-organ damage and mortality (p = 0.029, p = 0.08, respectively). New vascular lesions were evident on brain MRIs of 9 patients and brain CTs of 16 patients. CONCLUSION: Among the neurological symptoms of patients with COVID-19, headache appeared to indicate a protective factor against development of end-organ damage as well as mortality.

A peculiar presentation of stroke in young patients

Introduction: Young patients presenting with stroke to the emergency department (ED) is more uncommon. Atypical presentations of stroke in young patients presenting to ED include loss of consciousness, headache, vomiting, and blurring of vision. Young patients may present with stroke of infective causes which include bacterial, viral, fungal, and parasitic origin. Case discussion: A 24-year-old male presented to the ED in semiconscious state with decreased responsiveness along with complaints of fever since 2days and giddiness since 2days, followed by two episodes of vomiting and loss of consciousness. His vital data are blood pressure of 90/60mm Hg, and on examination, Glasgow Coma Scale (GCS) was E3V2M2, pupils are 1mm sluggishly reacting to light and showing upbeat and downbeat nystagmus on both sides, horizontal gaze palsy was present on the right side, all four limbs are in paraplegia and hyperreflexive to deep tendon reflexes, and ankle clonus is present. In view of poor GCS, the patient was intubated in the ED. The patient had a history of right maxillary fungal sinusitis 7 years back for which Functional Endoscopic Sinus Surgery (FESS) was done. The patient denied COVID infection and immunization. Neuroimaging and magnetic resonance imaging (MRI) brain plain with contrast revealed right maxillary fungal sinusitis extending up to the base of the skull with bilateral pontine and cerebellar infarcts, and there was complete occlusion of basilar artery occlusion. The patient was shifted to the intensive care unit (ICU);on further evaluation, the patient's serum homocysteine, protein C, and protein S were normal. Carotid Doppler was normal. Infective workup was done for TB and herpes simplex virus (HSV), bacterial workup was done, and then fungal workup was done for KOH mount, and tissue fungal smear revealed Aspergillus which was managed with antifungals like liposomal amphotericin B and voriconazole;FESS was done during hospitalization. The patient improved clinically and was discharged to the rehabilitation center. Conclusion: In this case, the cause of stroke was an improperly treated fungal sinusitis which invaded the basilar artery. Being an emergency physician, we should have high index of suspicion in the case of young patients presenting with stroke to ED;we need to consider their past history which gives clue toward the diagnosis of infective causes besides routine workup.

Two cases of COVID vaccine-induced immune thrombotic thrombocytopenia in Luxembourg

Introduction: In March 2021, a signal for embolic and thrombotic events with Vaxzevria (COVID-19 Vaccine AstraZeneca) was raised in Austria and Germany, and on 7 April 2021, the European Pharmacovigilance Risk Assessment Committee (PRAC) concluded that a causal relationship between Vaxzevria and thrombosis combined to thrombocytopenia (TTS) was at least a reasonable possibility [1]. TTS mechanism is close to heparin-induced thrombocytopenia [2,3]. We report two Luxembourg cases of TTS that occurred one before and one after this confirmed signal. Results: The first case is a 74-year-old woman, with no medical history, who received her first dose of Vaxzevria in March 2021. Fourteen days later, she was hospitalised for sudden loss of consciousness. On admission she had thrombocytopenia (18 G/L), D-Dimers >20 000 ng/mL, antithrombin III 79%, fibrinogen 0.69 g/dL. Brain CT scan showed cerebral and meningeal haemorrhages. She died three days later. Autopsy confirmed multiple intracranial haemorrhages and showed right transverse sinus organised thrombosis. Post-mortem analysis revealed positive heparin-Platelet Factor 4 (PF4) antibodies (HIPA and PIPA). The second case is a 31-year-old man with medical history of splenic infarction in 2017 during mononucleosis. He received his first dose of Vaxzevria in June 2021, and 12 days later was admitted for right lower limb and lumbar pain with severe thrombocytopenia (28 G/L), low fibrinogen and elevated D-Dimers. Angiography showed sub-occlusive cruoric impactions of the left carotid bifurcation, the sub-renal abdominal aorta and the right common femoral artery. PF4 antibody initially negative (Zymutest Hyphen) were positive with IMMUCOR technique. Management included clots removal, intravenous immunoglobulins started for 3 days and anticoagulation with sodium danaparoid. The patient recovered within one month without sequelae. Discussion/Conclusion: The quick communication about TTS signal and the rapid identification of its mechanism both allowed, as reported here for the second patient, adapted management (prohibiting heparin), with full recovery.

Evaluation of neurology consultations in a COVID-19 pandemic hospital, A retrospective study.

Background: Affinity of coronavirus disease to the central nervous system is not well known. Aim: We aimed to share the data of COVID-19 patients with neurological complaints in a pandemia hospital. Material and Method: Consultation results requested from the neurology clinic of Konya Meram State Hospital were retrospectively examined. PCR test positive patients, PCR negative patients with positive clinical, laboratory and radiological findings with COVID-19 were evaluated. Age, gender, history of neurological diseases, and neurological symptoms were recorded. Results: The reason for consultation was acute neurological symptom in 96 (84.2%) patients, counseling for treatment in chronic disease in 15 (13.2%) patients, and worsening in chronic disease in 3 (2.6%) patients. As neurological disorders, 22 (19.3%) had a history of previous stroke, 10 (8.8%) had dementia, 4 (3.5%) had epilepsy, 4 (3.5%) had Parkinson's disease, 3 (2.6%) had multiple sclerosis, 2 (1.8%) had myasthenia graves, and 1 (0.9%) had restless legs syndrome respectively. The most common reason for requesting consultation was changes in consciousness (56.1%). Of the 114 patients who requested neurology consultation, 65 (57%) were discharged, 49 (43%) were died. Conclusion: The change in consciousness was the reason in more than half of the patients who requested neurology consultation during COVID-19 follow-up. Impaired consciousness in a patient with COVID-19 may indicate a poor prognosis. If the studies planned in the near future can shed light on the cause of the unconsciousness developing in COVID-19, it will be promising in terms of treatment plans to reduce mortality.

Clinical neurological characteristics of geriatic patients with Coronavirus disease 2019 (COVID-19)

Background and objectives. Coronavirus Disease-2019 (COVID-19) is a respiratory infection caused by the severe acutrespiratory syndrome coronavirus (SARS-CoV-2). The COVID-19 associates multi clinical symptoms such as neurologicamanifestations with mild to advanced progression. This study aimed to determine the clinical neurological characteristicof geriatric patients with COVID-19. Methods. The study was an observational and descriptive study on 27 geriatric patients with COVID-19. All patients’ agwas over 60 years old who treated in the In-patient Department of Sanglah General Hospital, Denpasar, on July 2020 tJanuary 2021. The data had taken from medical records. Outcomes. The mean age of all patients was 70.41 (± 8.902) years which dominated by the male (51.9%). The majority omanifestations in this study were fever in 13 people (48.1%), unconsciousness in 10 people (37%), and hemiparesis in 1people (37%), and cough in 9 people (33.3%). Conclusion. The clinical neurology characteristics of geriatric patients with COVID-19 vary, which may involve general anneurological manifestations. Promptly accurate diagnosis is necessary for further management.
