Bilateral spontaneous pneumothorax in SARS-CoV-2 infection: A very rare,life-threatening complication

In the coronavirus disease 2019 (COVID-19) era, the presence of acute respiratory failure is generally associated with acute respiratory distress syndrome; however, it is essential to consider other differential diagnoses that require different, and urgent, therapeutic approaches. Herein we describe a COVID-19 case complicated with bilateral spontaneous pneumothorax. A previously healthy 45-year-old man was admitted to our emergency department with sudden-onset chest pain and progressive shortness of breath 17 days after diagnosis with uncomplicated COVID-19 infection. He was tachypneic and presented severe hypoxemia (75% percutaneous oxygen saturation). Breath sounds were diminished bilaterally on auscultation. A chest X-ray revealed the presence of a large bilateral pneumothorax. A thoracic computed tomography (CT) scan confirmed the large bilateral pneumothorax, with findings consistent with severe COVID-19 infection. Chest tubes were inserted, with immediate clinical improvement. Follow-up chest CT scan revealed resolution of bilateral pneumothorax, reduction of parenchymal consolidation, and formation of large bilateral pneumatoceles. The patient remained under observation and was then discharged home. Bilateral spontaneous pneumothorax is a very rare, potentially life-threatening complication in patients with COVID-19. This case highlights the importance of recognizing this complication early to prevent potentially fatal consequences.     

COVID-19 and the Human Eye: Conjunctivitis,a Lone COVID-19 Finding − A Case-Control Study

ObjectivesCOVID-19 has varied clinical manifestations, from asymptomatic to severe cases, and conjunctivitis is one of them, but sometimes a lone initial symptom is found to be present. The aim of this study was to identify the prevalence of conjunctivitis as the first symptom in COVID-19 patients in a primary healthcare unit.MethodologyA retrospective study was conducted, analyzing the presenting complains/symptoms and results of COVID-19-confirmatory tests.ResultsOut of the 672 cases that were sent for RT-PCR testing, only 121 (18%) were found to be positive. Among these, 2.67% patients had both conjunctivitis and COVID-19, 77.77% patients had unilateral eye affected, while 22.22% had bilateral conjunctivitis of varying degrees. Fifteen patients diagnosed to have both acute conjunctivitis and COVID-19 presented other symptoms associated with COVID-19 infection. Three patients had only acute conjunctivitis during their entire course of COVID-19.ConclusionsConjunctivitis is a symptom of COVID-19 and may be the first sign of the infection, until the onset of the classical manifestations; such patients may continue to be a viral reservoir. Physicians should not miss unilateral conjunctivitis as it can be the only presenting complaint of COVID-19 during the initial phase, which might worsen if undetected and can aid in the spread of the contagion.

Aortic Arch Thrombus and Pulmonary Embolism in a COVID-19 Patient

BackgroundCoronavirus disease 2019 (COVID-19) is associated with endothelial inflammation and a hypercoagulable state resulting in both venous and arterial thromboembolic complications. We present a case of COVID-19-associated aortic thrombus in an otherwise healthy patient.Case ReportA 53-year-old woman with no past medical history presented with a 10-day history of dyspnea, fever, and cough. Her pulse oximetry on room air was 84%. She tested positive for severe acute respiratory syndrome coronavirus 2 infection, and chest radiography revealed moderate patchy bilateral airspace opacities. Serology markers for cytokine storm were significantly elevated, with a serum D-dimer level of 8180 ng/mL (normal < 230 ng/mL). Computed tomography of the chest with i.v. contrast was positive for bilateral ground-glass opacities, scattered filling defects within the bilateral segmental and subsegmental pulmonary arteries, and a large thrombus was present at the aortic arch. The patient was admitted to the intensive care unit and successfully treated with unfractionated heparin, alteplase 50 mg, and argatroban 2 μg/kg/min.Why Should an Emergency Physician Be Aware of This?Mural aortic thrombus is a rare but serious cause of distal embolism and is typically discovered during an evaluation of cryptogenic arterial embolization to the viscera or extremities. Patients with suspected hypercoagulable states, such as that encountered with COVID-19, should be screened for thromboembolism, and when identified, aggressively anticoagulated.     

Case of the month: Buffalo chest: a case of bilateral pneumothoraces due to pleuropleural communication

Simultaneous spontaneous bilateral pneumothoraces, the presentation of separate right and left pneumothoraces together, is a rare event. The pleural cavities in humans are separated completely and the only previous reports of pleuropleural communication have been associated with major invasive thoracic procedures, specifically mediastinal surgery. The term “buffalo chest” has been coined for the condition on the basis that the buffalo or bison has a single pleural cavity, one of the few mammals to do so. We present the case of a woman with a past history of a single right sided spontaneous pneumothorax but no major thoracic surgery, who presented to the emergency department with a second spontaneous right pneumothorax that was under tension. After thoracostomy, she was found to have bilateral pneumothoraces which resolved with a unilateral chest drain demonstrating pleuropleural communication. We believe this to be the first reported case of such a presentation in the literature. The case demonstrates an unusual emergency presentation of a rare anatomical anomaly.     

Healthy neonate born to a SARS-CoV-2 infected woman: A case report and review of literature

BACKGROUNDSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly discovered coronavirus that has generated a worldwide outbreak of infections. Many people with coronavirus disease-2019 (COVID-19) have developed severe illness, and a significant number have died. However, little is known regarding infection by the novel virus in pregnant women. We herein present a case of COVID-19 confirmed in a woman delivering a neonate who was negative for SARS-CoV-2 and related it to a review of the literature on pregnant women and human coronavirus infections.CASE SUMMARYThe patient was a 36-year-old pregnant woman in her third trimester who had developed progressive clinical symptoms when she was confirmed as infected with SARS-CoV-2. Given the potential risks for both the pregnant woman and the fetus, an emergency cesarean section was performed, and the baby and his mother were separately quarantined and cared for. As a result, the baby currently shows no signs of SARS-CoV-2 infection (his lower respiratory tract samples were negative for the virus), while the mother completely recovered from COVID-19.CONCLUSIONAlthough we presented a single case, the successful result is of great significance for pregnant women with SARS-CoV-2 infection and with respect to fully understanding novel coronavirus pneumonia.     

Cardiovascular complications in COVID-19

BackgroundThe coronavirus disease of 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While systemic inflammation and pulmonary complications can result in significant morbidity and mortality, cardiovascular complications may also occur.ObjectiveThis brief report evaluates cardiovascular complications in the setting of COVID-19 infection.DiscussionThe current COVID-19 pandemic has resulted in over one million infected worldwide and thousands of death. The virus binds and enters through angiotensin-converting enzyme 2 (ACE2). COVID-19 can result in systemic inflammation, multiorgan dysfunction, and critical illness. The cardiovascular system is also affected, with complications including myocardial injury, myocarditis, acute myocardial infarction, heart failure, dysrhythmias, and venous thromboembolic events. Current therapies for COVID-19 may interact with cardiovascular medications.ConclusionsEmergency clinicians should be aware of these cardiovascular complications when evaluating and managing the patient with COVID-19.     

Bronchoscopy for diagnosis of COVID-19 with respiratory failure: A case report

BACKGROUNDAlthough the imaging features of coronavirus disease 2019 (COVID-19) are starting to be well determined, what actually occurs within the bronchi is poorly known. Here, we report the processes and findings of bronchoscopy in a patient with COVID-19 accompanied by respiratory failure.CASE SUMMARYA 65-year-old male patient was admitted to the Hainan General Hospital on February 3, 2020 for fever and shortness of breath for 13 d that worsened for the last 2 d. The severe acute respiratory syndrome coronavirus 2 nucleic acid test was positive. Routine blood examination on February 28 showed a white blood cell count of 11.02 × 10⁹/L, 86.9% of neutrophils, 6.4% of lymphocytes, absolute lymphocyte count of 0.71 × 10⁹/L, procalcitonin of 2.260 ng/mL, and C-reactive protein of 142.61 mg/L. Oxygen saturation was 46% at baseline and turned to 94% after ventilation. The patient underwent video bronchoscopy. The tracheal cartilage ring was clear, and no deformity was found in the lumen. The trachea and bilateral bronchi were patent, while the mucosa was with slight hyperemia; no neoplasm or ulcer was found. Moderate amounts of white gelatinous secretions were found in the dorsal segment of the left inferior lobe, and the bronchial lumen was patent after sputum aspiration. The right inferior lobe was found with hyperemia and mucosal erosion, with white gelatinous secretion attachment. The patient’s condition did not improve after the application of therapeutic bronchoscopy.CONCLUSIONFor patients with COVID-19 and respiratory failure, bronchoscopy can be performed under mechanical ventilation to clarify the airway conditions. Protection should be worn during the process. Considering the risk of infection, it is not necessary to perform bronchoscopy in the mild to moderate COVID-19 patients.     

Acute Cerebellar Ataxia in COVID-19 Infection: A Case Report

BackgroundThe outbreak of coronavirus disease 2019 (COVID-19) has been widely reported to cause symptoms such as fever, cough, sore throat, fatigue, and shortness of breath. Neurologic complications have not been widely reported without associated respiratory symptoms. These neurologic manifestations have been found mostly in the elderly. There has been no report of ataxia or COVID-19 cerebellitis in the young adult population without associated respiratory symptoms.Case ReportHere we report the case of a 30-year-old patient who presented with isolated cerebellar symptoms and was diagnosed with COVID-19 cerebellitis.Why Should an Emergency Physician Be Aware of This?It is important for emergency physicians to know that COVID-19 can have many clinical manifestations and to have a high level of suspicion with acute neurologic symptoms.     

Aromatherapy blend of thyme,orange, clove bud,and frankincense boosts energy levels in post-COVID-19 female patients: A randomized,double-blinded,placebo controlled clinical trial

BackgroundA large proportion of individuals who have recovered from an acute COVID-19 infection continue to experience symptoms months later. Post-acute COVID-19 (long-haul COVID-19) can range from serious complications to quality of life symptoms such as fatigue or insomnia. The purpose of this study was to evaluate the potential for inhalation of essential oils to improve energy levels among otherwise healthy female survivors of acute COVID-19 who experience a lack of energy more than five months after recovery. This study was conducted in the United States in late 2021.MethodThis was a randomized double blind, placebo controlled trial to evaluate the potential for inhalation of Longevity™, a proprietary essential oil blend manufactured by Young Living Essential Oils (Lehi, Utah, USA), on energy levels among female survivors of COVID-19 who continue to experience fatigue more than 5 months recovery from the acute infection. Forty women were randomized to two groups: intervention and placebo. Both groups inhaled the assigned product twice daily for fourteen consecutive days. Fatigue scores were measured using the Multidimensional Fatigue Symptom Inventory (MFSI). Secondary outcomes included scores on each of the MFSI’s ten subscales.ResultsIndividuals who inhaled the essential oil blend for 2 weeks had significantly lower fatigue scores after controlling for baseline scores, employment status, BMI, olfactory function, and time since diagnosis, with a large effect size (F (1,39) = 6.15, p = .020, partial eta squared = 0.198). Subscale analysis identified subscales of vigor, as well as global, behavioral, general, and mental fatigue as benefiting from the intervention. This study provides evidence that a proprietary aromatherapy blend can significantly improve energy levels among women who are experiencing fatigue after recovering from COVID-19.     

COVID-19 respiratory support in the emergency department setting

IntroductionSevere acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), which causes the coronavirus disease 2019 (COVID-19), may result in severe complications, multiorgan dysfunction, acute respiratory failure, and death. SARS-CoV-2 is highly contagious and places healthcare workers at significant risk, especially during aerosol-generating procedures, including airway management.ObjectiveThis narrative review outlines the underlying respiratory pathophysiology of patients with COVID-19 and discusses approaches to airway management in the emergency department (ED) based on current literature.DiscussionPatients presenting with SARS-CoV-2 infection are at high risk for acute respiratory failure requiring airway management. Among hospitalized patients, 10–20% require intensive care unit admission, and 3–10% require intubation and mechanical ventilation. While providing respiratory support for these patients, proper infection control measures, including adherence to personal protective equipment policies, are necessary to prevent nosocomial transmission to healthcare workers. A structured approach to respiratory failure in these patients includes the use of exogenous oxygen via nasal cannula or non-rebreather, as well as titrated high-flow nasal cannula and non-invasive ventilation. This review offers several guiding principles and resources designed to be adapted in conjunction with local workplace policies for patients requiring respiratory support.ConclusionsWhile the fundamental principles of acute respiratory failure management are similar between COVID-19 and non-COVID-19 patients, there are some notable differences, including a focus on provider safety. This review provides an approach to airway management and respiratory support in the patient with COVID-19.     

Hypercapnic Coma Due to Spontaneous Pneumothorax: Case Report and Review of the Literature

Background: Hypercapnic coma is a rare differential diagnosis in the unconscious patient. One underlying mechanism may be hypoventilation due to spontaneous pneumothorax. Although hypercapnia is not a typical finding in spontaneous pneumothorax in patients with otherwise healthy lungs, under certain circumstances, hypercapnia may readily develop. Objectives: We report a rare case of profound hypercapnic coma due to spontaneous pneumothorax after contralateral pneumonectomy. In addition, we review other causes of hypercapnic coma and its outcome and discuss the relationship between arterial carbon dioxide partial pressure and level of consciousness. Case Report: An 85-year-old man without evidence of trauma or intoxication presented unconscious to our Emergency Department. The physical examination and X-ray study revealed a left-sided spontaneous pneumothorax. A right-sided pneumonectomy 25 years earlier had promoted the development of profound hypercapnic coma. After insertion of a thoracic drain, the coma rapidly resolved without any neurological deficit. Conclusions: Although severe hypercapnia is usually due to decompensation of chronic lung disease, pneumothorax potentially may cause hypercapnic coma. Review of the literature suggests that there is no close correlation between arterial pCO₂ (partial pressure of CO₂) levels and the degree of impairment of consciousness; however, levels exceeding 80 mm Hg are likely associated with significantly impaired consciousness. Hypercapnic coma usually resolves without neurological deficit as arterial pCO₂ tensions decline.     

The bug stops with me: Prevention of COVID-19 nosocomial transmission during radiographic procedures

IntroductionNosocomial transmission of Coronavirus Disease 2019 (COVID-19) is a preventable risk to the patient population and radiographer workforce. This article aims to describe the prevention of COVID-19 nosocomial transmission during radiographic procedures by the utilization of stringent infection prevention measures at a leading tertiary hospital in Singapore.MethodsThe implemented measures are the appropriate use of personal protective equipment, staff education, infection controls measures such as equipment disinfection, physical distancing and segregation of staff and patients.ResultsDespite the handling of 1637 COVID-19 cases as of July 25, 2020, there has not been a single case of known nosocomial transmission of the disease in the institution.DiscussionThe absence of nosocomial transmission suggests that the implemented measures are adequate. These measures will need to be sustainable for the long term in order to ensure continued success.ConclusionRadiographers are a crucial part of the team in the fight against COVID-19 and are at risk of contracting COVID-19. Strict adherence to appropriate infection control measures is essential for the safety of Radiology staff and their patients, and the successful control of this pandemic.     

Sonographic diagnosis of bilateral pneumothorax following an acupuncture session

We present the case of a 57‐year‐old woman who presented with the acute onset of chest pain and dyspnea, which started while undergoing acupuncture for neck pain. A bedside ultrasound revealed bilateral pneumothoraces, which were confirmed radiographically. We discuss the details of the case, the sonographic features of pneumothorax, and the role of bedside ultrasonography in the assessment of an acutely dyspneic patient. © 2013 Wiley Periodicals, Inc.

Fecal Microbiota Transplantation for Recurrent C difficile Infection During the COVID-19 Pandemic: Experience and Recommendations

ObjectiveTo report experience with fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (rCDI) and provide recommendations for management of rCDI and donor testing during the COVID-19 pandemic.MethodsA retrospective study of patients with rCDI who underwent FMT from May 26, 2020, to September 30, 2020, with stool from well-screened donors with health and infectious screening and a newly implemented strategy for COVID-19 screening with every 2-week bookend testing with stool quarantine. Patients were followed up for development of rCDI and COVID-19.ResultsOf the 57 patients who underwent FMT for rCDI, 29 were tested for COVID-19 via nasopharyngeal polymerase chain reaction (PCR) and 22 via serology. All results were negative, except for 1 positive serology. Donor testing every 2 weeks for COVID-19 via serology and nasopharyngeal swab PCR was negative, except for 2 donors at 1 center who were excluded. Three patients had rCDI after FMT, and 1 underwent repeat FMT. One patient developed respiratory symptoms suggestive of COVID-19 and tested negative via nasopharyngeal PCR. Eleven patients who underwent COVID-19 testing for elective procedures or hospitalizations tested negative. No SARS-CoV-2 transmission was noted.ConclusionsWith appropriate donor screening, FMT can be performed safely for rCDI during the COVID-19 pandemic. Development of a validated stool assay for SARS-CoV-2 will simplify this process further.     

Immediate pneumothorax after neurosurgical procedures

ObjectivePneumothorax after neurosurgical procedures is very rare and incompletely understood. This study was performed to explore the clinical characteristics and pathogenesis of pneumothorax after neurosurgery.MethodsWe retrospectively evaluated patients admitted from December 2016 to April 2019 for treatment of spontaneous intracranial hemorrhage. The inclusion criteria were neurosurgical procedures (open surgeries or endovascular intervention) performed under general anesthesia, no performance of central venous puncture during surgery, and occurrence of pneumothorax immediately after the neurosurgical procedure.ResultsEight patients developed pneumothorax after neurosurgical procedures for spontaneous intracranial hemorrhage under general anesthesia. Of the eight patients, seven had aneurysmal subarachnoid hemorrhage and one had left temporal–parietal hemorrhage. The lung injury prediction score (LIPS) was 3, 4, 5, 6, and 9.5 in three, one, two, one, and one patient, respectively. During the operation, volume-controlled ventilation (tidal volume, 8–10 mL/kg) was selected for all patients.ConclusionsNeurogenic pulmonary edema, inappropriate mechanical ventilation, and stimulation by endotracheal intubation might conjointly contribute to postoperative pneumothorax. To avoid this rare entity, mechanical ventilation with a low tidal volume or low pressure during general anesthesia should be adopted for patients with hemorrhagic cerebrovascular diseases involving the temporal lobe and a LIPS of >3.     

Spontaneous tension pneumothorax as a complication of Coronavirus disease 2019: Case report and literature review

Primary spontaneous tension pneumothorax (STP) is a rare and life‐threatening condition. We report a case of COVID‐19‐pneumonia patient who developed STP as a complication. He had a prolonged hospital stay and was ultimately discharged asymptomatic. A systematic literature search was performed to review studies (N=12) reporting STP in the setting of COVID‐19.
