Intracranial Pressure Dynamics and Cerebral Vasomotor Reactivity in Coronavirus Disease 2019 Patient With Acute Encephalitis.

We describe the intracranial pressure dynamics and cerebral vasomotor reactivity in a coronavirus disease 2019 patient with acute encephalitis treated with cerebrospinal fluid drainage and therapeutic plasma exchange. DATA SOURCES: Coronavirus disease ICU, Uppsala University Hospital, Sweden. STUDY SELECTION: Case report. DATA EXTRACTION: Radiology, intracranial pressure, intracranial compliance (correlation between intracranial pressure amplitude and mean intracranial pressure), cerebral vasomotor reactivity (pressure reactivity index), arterial blood pressure, cerebrospinal fluid chemistry, and treatment. DATA SYNTHESIS: None. CONCLUSIONS: This is the first reported case of intracranial pressure monitoring in a patient with acute encephalitis following coronavirus disease 2019. Intracranial pressure data exhibited a high incidence of plateau waves with intracranial pressure insults above 40 mm Hg that required cerebrospinal fluid drainage. Intracranial compliance was low, and pressure reactivity was intact. It is probable that the combination of low intracranial compliance and intact pressure autoregulation explain the high degree of plateau intracranial pressure waves and intracranial pressure variability. This case illustrates that it could be of value to consider intracranial pressure monitoring in selected coronavirus disease 2019 patients with suspicion of increased intracranial pressure to be able to confirm and treat intracranial hypertension if needed. In this patient, therapeutic plasma exchange was safe and efficacious as the level of neuroinflammation decreased and the patient regained consciousness.

Persistence of Elevated Procalcitonin in a Patient with Coronavirus Disease 2019 Uncovered a Diagnosis of Medullary Thyroid Carcinoma.

OBJECTIVE: During the ongoing coronavirus disease 2019 pandemic, procalcitonin (PCT) levels have proven useful in assisting clinicians to diagnose bacterial superinfection. However, in the absence of signs of infection or at the resolution thereof, inappropriately and persistently high PCT levels may suggest and reveal the presence of other pathologies. We report a patient with severe acute respiratory syndrome coronavirus 2 pneumonia with initially elevated PCT levels that persisted during recovery, prompting the diagnosis of medullary thyroid carcinoma (MTC). METHODS: A 43-year-old man presented with a 2-day history of fever, sneezing, sore throat, and dry cough. His PCT was 94 ng/mL (normal value, 0.00-0.10 ng/mL), and he was positive for severe acute respiratory syndrome coronavirus 2 RNA. RESULTS: Empirical antibiotic therapy was administered for 7 days, but despite a clinical improvement, serum PCT remained high (84 ng/mL). Serum calcitonin (CTN) was 2120 pg/mL (normal, ≤12 pg/mL). Cytologic examination of thyroid nodules and CTN measurement of the aspiration needle washout confirmed MTC. The patient underwent total thyroidectomy with bilateral cervical lymph node dissection. Lowered CTN (986 pg/mL) and PCT (16 ng/mL) levels were observed 48 hours after surgery. A close follow-up was planned following the results of RET gene analysis. CONCLUSION: PCT can be a useful biochemical marker of MTC suspicion in patients with inflammatory conditions and persistently elevated PCT, even after resolution. In our case, high levels of PCT in a patient with coronavirus disease 2019 pneumonia without signs of bacterial infection led to MTC diagnosis.

Pre-test probability for SARS-Cov-2-related infection score: The PARIS score.

INTRODUCTION: In numerous countries, large population testing is impossible due to the limited availability of RT-PCR kits and CT-scans. This study aimed to determine a pre-test probability score for SARS-CoV-2 infection. METHODS: This multicenter retrospective study (4 University Hospitals) included patients with clinical suspicion of SARS-CoV-2 infection. Demographic characteristics, clinical symptoms, and results of blood tests (complete white blood cell count, serum electrolytes and CRP) were collected. A pre-test probability score was derived from univariate analyses of clinical and biological variables between patients and controls, followed by multivariate binary logistic analysis to determine the independent variables associated with SARS-CoV-2 infection. RESULTS: 605 patients were included between March 10th and April 30th, 2020 (200 patients for the training cohort, 405 consecutive patients for the validation cohort). In the multivariate analysis, lymphocyte (<1.3 G/L), eosinophil (<0.06 G/L), basophil (<0.04 G/L) and neutrophil counts (<5 G/L) were associated with high probability of SARS-CoV-2 infection but no clinical variable was statistically significant. The score had a good performance in the validation cohort (AUC = 0.918 (CI: [0.891-0.946]; STD = 0.014) with a Positive Predictive Value of high-probability score of 93% (95%CI: [0.89-0.96]). Furthermore, a low-probability score excluded SARS-CoV-2 infection with a Negative Predictive Value of 98% (95%CI: [0.93-0.99]). The performance of the score was stable even during the last period of the study (15-30th April) with more controls than infected patients. CONCLUSIONS: The PARIS score has a good performance to categorize the pre-test probability of SARS-CoV-2 infection based on complete white blood cell count. It could help clinicians adapt testing and for rapid triage of patients before test results.

Mortality of patients with solid and haematological cancers presenting with symptoms of COVID-19 with vs without detectable SARS-COV-2: a French nationwide prospective cohort study.

BACKGROUND: Over 30 million COVID-19 cases have been diagnosed worldwide from late 2019. Among frail persons, cancer patients are at high risk of death from COVID-19. METHODS: The French prospective cohort ONCOVID-19 enrolled patients with solid or haematological tumour, receiving anticancer treatment and presenting with clinical symptoms suggestive of COVID-19. COVID-19 was confirmed through detectable SARS-CoV2 by RT-PCR (repeated twice if negative first) and/or specific CT-scan. The study aims to assess the 28-day mortality rate after the first COVID test. RESULTS: From March 1st to May 21st 2020, 23 French cancer centres and hospitals enrolled 1230 cancer patients with suspicion of COVID-19, including 1162 (94.5%) matching the inclusion criteria. We identified 425 (36.6%) COVID-19 positive patients including 155 (13.3%) diagnosed with CT-scan only, while 737 (63.4%) patients were COVID-19 negative. Death at day-28 occurred in 116/425 (27.8%) COVID-19 positive patients, and in 118/737 (16.3%) COVID-19 negative patients (p < 0·0001). With a median follow-up of 2.1 (1.6-2.4) months, 310 (26.7%) deaths were reported including 143 (33.6%) in the COVID-19 positive population, and 167 (22.7%) in the COVID-19 negative patients. Male gender, age, metastatic disease, immunosuppressive treatments, lymphopenia, COVID-19 diagnosis and diabetes were independent risk factors for death. CONCLUSION: Patients with solid and haematological cancers presenting COVID-19 symptoms with SARS-CoV-2 RT-PCR confirmed or not are both at high-risk of early mortality. COVID-19 is reported as the cause of death in 50% of COVID-19 positive patients with cancer. CLINICAL TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov, number NCT04363632.

Diagnostic interval for non-screening patients undergoing mammography during the COVID-19 pandemic.

OBJECTIVE: During the COVID-19 pandemic, there was a temporary cessation of mammography screening. However, in some facilities, diagnostic breast imaging services continued for patients with a high clinical suspicion of breast cancer. The objective of this study was to evaluate changes in the diagnostic interval (DI) of non-screening patients presenting for diagnostic mammography during the first wave of the COVID-19 pandemic. METHODS: Retrospective chart review was performed on patients presenting for non-screening diagnostic mammography from April 1 to June 30, 2020 (pandemic group) and April 1 to June 30, 2019 (pre-pandemic group). Age, reason for referral, number and type of imaging studies/biopsies necessary for a final diagnosis were recorded. Diagnostic interval (DI) was defined as the number of days from the date of the diagnostic mammogram to the date of the final diagnosis. RESULTS: Compared to the pre-pandemic group (n = 64), the pandemic group (n = 77) showed a reduction in DI of the entire cohort (pandemic: 1 day; pre-pandemic: 15 days, p < 0.0001) for patients not requiring tissue sampling (pandemic: 1 day; pre-pandemic: 11 days, .p < 0.0001) and those requiring tissue sampling with benign pathology (pandemic 9 days; pre-pandemic, 33 days, p = 0.0002). A higher percentage of patients in the pandemic group had their assessment completed during the initial visit (pandemic: 50.6%; pre-pandemic: 23.4%, p = 0.0009). CONCLUSION: During the first wave of the COVID-19 pandemic, the DI for patients with non-screening-related diagnostic mammography was significantly shorter, with a higher percentage of patients completing their assessments on the initial visit, compared to one year prior. KEY POINTS: • Despite reductions in manpower and clinical services, during pandemic times, it is possible to maintain a diagnostic breast imaging service for women at high clinical suspicion for breast cancer. • During pandemic times, breast imaging departments should consider restructuring to a Rapid Diagnostic Unit model with a navigation team that follows patients through the assessment process to a final diagnosis. • Departmental restructuring and patient navigation during pandemic times could either maintain or shorten the diagnostic interval for patients presenting for diagnostic mammography.

Case of COVID-19-induced vestibular neuritis in a child.

Since the outbreak of the COVID-19 pandemic, there has been a growing need to fully understand all the possible clinical features of the epidemic, which often presents with unusual manifestations, especially in children. In this report, we describe the case of a child with a COVID-19 infection and suffering exclusively from vertigo and fever. Altogether, considering the clinical manifestation, laboratory tests and imaging, given the patient's positivity to SARS-CoV-2 infection and its neurotropic potential, we assumed that the child had COVID-19-induced vestibular neuritis, which, in consideration of the spontaneous improvement of symptoms, did not require any therapeutic adjustments, apart from the natural compensation of the central nervous system.This case suggests the importance of having an index of suspicion for a COVID-19 infection in patients with paediatrics presenting with vertigo and adds valuable information to the limited literature on COVID-19 presentation and management in children.

Pericardial Diseases in COVID19: a Contemporary Review.

PURPOSE OF REVIEW: Coronavirus disease 2019 (COVID19) involves the heart, including pericardium. This article reviews the possible pathophysiological mechanisms in pericardial involvement in COVID19 and pericardial manifestations of COVID19. It also summarizes the patients with pericarditis secondary to COVID19 and outlines the contemporary treatment strategies in this patient population. RECENT FINDINGS: A high degree of suspicion is required to identify the pericardial involvement in COVID19 patients. It is proposed that an underlying hyperinflammatory reaction in COVID19 leads to pericardial inflammation. Acute pericarditis with or without myocardial involvement is diagnosed on clinical presentation, serum inflammatory markers, electrocardiogram, and echocardiogram. Multimodality imaging may also have an additional diagnostic value. Patients are usually managed medically, but some patients develop a life-threatening pericardial tamponade necessitating pericardial drainage. Pericardial involvement is an important clinical manifestation of COVID19 requiring a proper workup. Timely diagnosis and a specific management plan based on the presentation and concomitant organ involvement usually lead to a complete recovery.

Significance of Lung Ultrasound in Patients with Suspected COVID-19 Infection at Hospital Admission.

With a lung ultrasound (LUS) the typical findings are interstitial pneumonia. COVID-19 pneumonia is often manifested in sub-pleural areas, which is preferably detected by sonography. An RT-PCR test cannot always ensure a safe differentiation of COVID-19- and non-diseased cases. Clinically challenging is that a reliable and time efficient decision regarding COVID-19 suspects requiring isolation. Therefore, this study was aimed at evaluating the significance of LUS in symptomatic patients with COVID-19 suspicion at hospital admission. A total of 101 patients admitted to a suspect ward with COVID-19-typical symptoms were assessed. All patients received prospectively a standardized LUS at admission. Patients were classified as LUS-positive and -negative cases based on a specific LUS score. The RT-PCR test in combination with the clinical findings served as a reference. Correctly classified were 14/15 COVID-19 diseased suspects as LUS-positive (sensitivity: 93.3%). Twenty-seven out of 61 non-positive cases were classified as false positive with LUS (specificity: 55.7%). In 34/35 patients who were assessed as LUS negative, no COVID-19 disease was detected during the hospitalization. The PPV and NPV of the LUS were 34.1% and 97.1%. LUS is a valuable tool in symptomatic patients for the assessment of COVID-19-disease. The high negative predictive value of LUS is helpful to rule out the disease.

Appropriateness of lung ultrasound for the diagnosis of COVID-19 pneumonia.

BACKGROUND: Chest radiography (CXR) and computerized tomography (CT) are the standard methods for lung imaging in diagnosing COVID-19 pneumonia in the intensive care unit (ICU), despite their limitations. This study aimed to assess the performance of bedside lung ultrasound examination by a critical care physician for the diagnosis of COVID-19 pneumonia during acute admission to the ICU. METHOD: This was an observational, prospective, single-center study conducted in the intensive care unit of Adan General Hospital from April 10, 2020, to May 26, 2020. The study included adults with suspicion of COVID-19 Infection who were transferred to the ICU. Patients were admitted to the ICU directly from the ED after reverse transcriptase-polymerase chain reaction (RT-PCR) swabs were sent to the central virology laboratory in Kuwait, and the results were released 16 to 24 hours after the time of admission. A certified intensivist in critical care ultrasound performed the lung ultrasound within 12 hours of the patient's admission to the ICU.The treating physician confirmed the diagnosis of COVID-19 pneumonia based on a set of clinical features, inflammatory markers, biochemical profile studies, RT-PCR test results, and CXR. RESULTS: Of 77 patients with suspected COVID-19 pneumonia, 65 (84.4%) were confirmed. The median age of the patients was 48 (31-68) years, and 51 (71%) were men.In the group of patients with confirmed COVID-19 pneumonia, LUS revealed four signs suggestive of COVID-19 pneumonia in 63 patients (96.9%) (sensitivity 96.9%, CI 85%-99.5%). Two patients presented with unilateral lobar pneumonia without other ultrasonic signs of COVID-19 pneumonia but with positive RT-PCR results. Among patients in the group without COVID-19 pneumonia who had negative RT-PCR results, 11 (91.7%) were LUS negative for COVID-19 pneumonia (specificity 91.7%, 95% CI 58.72%-99.77%). CONCLUSIONS: During the COVID-19 outbreak, LUS allows the identification of early signs of interstitial pneumonia. LUS patterns that show a combination of the four major signs offer high sensitivity and specificity compared to nasopharyngeal RT-PCR.

Patient perspective on telemedicine replacing physical consultations in urology during the COVID-19 lockdown in Denmark.

OBJECTIVE: In March-April 2020, during the coronavirus disease 2019 (COVID-19) pandemic lockdown in Denmark, the Danish Health Authorities recommended that, where possible, face-to-face patient-physician consultations be replaced by telephone consultations. The aim of this study was to obtain patients' evaluation of their telemedicine experience. METHODS: Patients who were candidates for telemedicine consultations were recruited based on their urological ailment, necessity for follow-up and comorbidity. New referrals including patients with suspicion of cancer were not candidates for telemedicine. In total, 548 patients had their appointment altered during the period from 13 March to 30 April 2020. Postal questionnaires were sent to 548 patients and 300 (54.7%) replied. RESULTS: In total, 280 patient answered, 224 (80%) men and 56 (20%) women, mean age 69 years (range 18-91) of whom 180 (64.3%) had a benign and 100 (35.7%) a malignant diagnosis. Twenty (6.7%) respondents did not remember their telephone consultation and were therefore excluded. Telephone consultation satisfaction was reported by 230 (85.0%) patients, but they would not prefer video consultations over telephone consultations, and only 102 (36.4%) would prefer telephone consultations in the future. Patients' age, sex and distance to the hospital did not seem to be associated with telephone consultation satisfaction (age p = 0.17; sex p = 0.99; distance p = 0.27, respectively). In total, 226 (80.7%) were medically assessed as being at risk for COVID, but 74 (26.4%) subjectively evaluated themselves as being at risk. CONCLUSIONS: In general (85.0%), urological patients were satisfied with telephone consultations.

Patient safety recommendations and management in patients with COVID-19 pneumonia suspicion: a retrospective study.

OBJECTIVE: Since December 2019, new pneumonia of unknown aetiology broke out in Wuhan, Hubei province, China. Subsequently, a virus, later named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified as the causative agent of the disease. Currently, the epidemic has spread all over the world. The most common manifestations of COVID-19 are fever, fatigue and dry cough. At the moment, the nuclide acid test is the gold standard method for the diagnosis of this infection. METHODS: In the present paper, we report our experience with all patients who came to the Emergency Department from March 1 to April 1, 2020, with suggestive symptoms of COVID-19 infection. Patients: they all underwent a first oropharyngeal and nasopharyngeal swab in the emergency department and, if negative, a second one after at least 24 hours. RESULTS: Our study shows how the results obtained at time zero are usually identical to the ones obtained after 24 hours. We thus suggest, in patients with high suspicion of COVID19 and a negative result at the first swab, to repeat the test after at least 48 hours, during which patients with symptoms of COVID-19 pneumonia disease should be kept in isolation to avoid the risk of contagion. CONCLUSIONS: these measures and in particular the early identifica-tion of cases with consequent isolation will allow the containment of the spread of the virus, representing one of the fundamental measures to guarantee and strengthen the control of the infection to reduce hospital admissions, the overload of national health service and health costs.

Rapid Clinical Deterioration With Sepsis and Persistent Hypertension in a Pediatric Patient During Recent COVID-19 Crisis.

We present a child with a clear and classic COVID-19 symptomatic picture that rapidly progressed to sepsis with persistent hypertension. This patient, a five-year-old Hispanic female child was brought to our emergency department on March 21, 2020, with fever, productive cough, shortness of breath with chest tightness, abdominal pain, and diarrhea for a week. Her condition deteriorated rapidly, and she developed sepsis within 24 hours, needing intensive care unit admission and ventilator support. She tested negative for COVID-19 Biofire ® nucleic acid tests (BioFire Diagnostics, Salt Lake City, Utah 84108 USA); however, she was recently exposed to COVID-19 cases at her school. This case highlights the importance of a high index of COVID-19 suspicion in children in the endemic areas despite negative COVID-19 tests for keeping a watchful eye to prevent sudden deterioration and unexpected complications.

The incidence of anosmia in patients with laboratory-confirmed COVID 19 infection in India: An observational study.

BACKGROUND AND AIMS: Acute loss of smell or anosmia is a common and sometimes the only symptom observed in patients with coronavirus disease-2019 (COVID-19). The objective of the study was to determine the prevalence, time of onset, and duration of anosmia in patients with COVID-19 infection and the association of anosmia with other symptoms and eosinophil count. MATERIAL AND METHODS: Two hundred patients with laboratory-confirmed COVID-19 infection, who were asymptomatic or mildly symptomatic were assessed for olfaction with a nonirritant odor. The presence of anosmia was recorded, and a questionnaire integrating the anosmia reporting tool was filled. Patients with anosmia/hyposmia were followed telephonically at 7 and 14 days for resolution of anosmia and other symptoms. The presence of anosmia was correlated with eosinophil count. RESULTS: Of the 200 COVID-19 patients, 87% were symptomatic. More than half of the patients had fever (56%). Anosmia was observed in 30% of the patients and hyposmia in 4% of patients. In 41% of the patients, olfactory loss was reported before diagnosis. The mean duration of anosmia was 7.8 (± 5) days; 97% of patients recovered with a resolution of symptoms within 2 weeks. Ageusia was the most commonly and significantly associated symptom with anosmia (66%, n = 45) followed by sore throat (41%), and rhinorrhea (28%). The symptoms in both the sexes were comparable. Absolute eosinophil count of <40/µL was observed in 59 patients (29.5%) and an absolute eosinophil count of 0 in 17 patients (8.5%). Among the 68 anosmic patients, 36 (47%) patients had eosinopenia, which was statistically significant. CONCLUSION: Anosmia is an early and sometimes the only symptom in approximately one-third of the patients with COVID-19 infection. Eosinophil count should be checked in anosomic patient with suspicion of COVID-19 infection. Objective tools for olfactory and gustatory assessment should be brought into practice for early and prompt diagnosis to control the spread of the disease.

D-Dimer Level and Neutrophils Count as Predictive and Prognostic Factors of Pulmonary Embolism in Severe Non-ICU COVID-19 Patients.

The incidence of pulmonary embolism (PE) is high during severe Coronavirus Disease 2019 (COVID-19). We aimed to identify predictive and prognostic factors of PE in non-ICU hospitalized COVID-19 patients. In the retrospective multicenter observational CLOTVID cohort, we enrolled patients with confirmed RT-PCR COVID-19 who were hospitalized in a medicine ward and also underwent a CT pulmonary angiography for a PE suspicion. Baseline data, laboratory biomarkers, treatments, and outcomes were collected. Predictive and prognostics factors of PE were identified by using logistic multivariate and by Cox regression models, respectively. A total of 174 patients were enrolled, among whom 86 (median [IQR] age of 66 years [55-77]) had post-admission PE suspicion, with 30/86 (34.9%) PE being confirmed. PE occurrence was independently associated with the lack of long-term anticoagulation or thromboprophylaxis (OR [95%CI], 72.3 [3.6-4384.8]) D-dimers ≥ 2000 ng/mL (26.3 [4.1-537.8]) and neutrophils ≥ 7.0 G/L (5.8 [1.4-29.5]). The presence of these two biomarkers was associated with a higher risk of PE (p = 0.0002) and death or ICU transfer (HR [95%CI], 12.9 [2.5-67.8], p < 0.01). In hospitalized non-ICU severe COVID-19 patients with clinical PE suspicion, the lack of anticoagulation, D-dimers ≥ 2000 ng/mL, neutrophils ≥ 7.0 G/L, and these two biomarkers combined might be useful predictive markers of PE and prognosis, respectively.

Neurologic aspects of coronavirus disease of 2019 infection.

PURPOSE OF REVIEW: Central and peripheral nervous system manifestations of coronavirus disease 2019 (COVID-19) have been frequently reported and may cause significant morbidity and mortality. This review details the latest evidence on the neuropathogenesis and neurologic complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. RECENT FINDINGS: Commonly reported neurologic complications include toxic-metabolic encephalopathy, acute cerebrovascular disorders, seizures, and anoxic-brain injury. These complications represent secondary injury due to COVID-19 related hypoxia, sepsis, hypercoagulability, or hyperinflammation. Postinfectious complications, such as encephalitis, postinfectious demyelination, and Guillain-Barré syndrome have been reported, but are rare. Recent reports of persistent neurocognitive symptoms highlight the possibility of lasting impairment. SUMMARY: Although some neurologic complications should be treated with standard practices, further investigations are still needed to determine the optimal treatment of COVID-related neurologic complications, such as ischemic stroke. Entering into the next phase of the pandemic, investigations into the long-term neurologic and cognitive impacts of SARS-CoV-2 infection will be needed. Clinicians must have a high clinical suspicion for both acute and chronic neurologic complications among COVID-19 patients.

COVID-19 Related Acute Hemorrhagic Necrotizing Encephalitis: A Report of Two Cases and Literature Review.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, has proven neurotropism and causes a multitude of neurologic manifestations. Acute hemorrhagic necrotizing encephalitis (AHNE), though rare, can be seen in patients with severe infection and is associated with devastating neurologic outcomes. The true prevalence of this syndrome is unknown due to underrecognition, difficulty in timely acquisition of neuroimaging, and high mortality in this subset of patients escaping detection. It is a distinct clinicoradiological syndrome, with patients suffering from rapidly worsening encephalopathy and coma within the first two weeks of severe illness and hemorrhagic necrotizing parenchymal changes on neuroimaging. The pathophysiology of this syndrome is unclear but hypothesized to occur due to cytokine storm, blood-brain-barrier dysfunction, and direct viral-mediated endotheliopathy. Diagnosis requires a high index of suspicion in patients who have unexplained persistent severe encephalopathy associated with COVID-19 infection. Most patients have elevated systemic inflammatory markers and severe lung disease with hypoxic respiratory failure requiring mechanical ventilation. MRI is the imaging modality of choice, with a distinct neuroimaging pattern. CSF (cerebrospinal fluid) studies have a low yield for viral particle detection with currently available testing. While long-term outcomes are unclear, early immunomodulatory treatment with intravenous immunoglobulin, plasma exchange, and steroids may portend a favorable outcome. We discuss two cases of COVID-19 related AHNE and also include a pertinent literature search of similar cases in PubMed to consolidate the AHNE clinical syndrome, neuroimaging characteristics, management strategies, and reported short-term prognosis.

High-Resolution CT Chest Findings in Suspected COVID-19 Pneumonia Patients With Negative Real-Time Polymerase Chain Reaction Assay.

Objective The study was conducted with the objective of describing High-resolution computed tomography (HRCT) chest findings of clinically suspected COVID-19 patients having a negative real-time polymerase chain reaction (RT-PCR) assay as well as prevalence and distribution of the HRCT chest manifestations consistent with the diagnosis of COVID-19 pneumonia. Methods This descriptive cross-sectional study was conducted prospectively on a total of 48 patients with high clinical suspicion for COVID-19 and a negative RT-PCR assay that was presented to the Diagnostic Radiology Department of Capital Hospital, Islamabad from July 2020 to December 2020. These patients were included via non-probability consecutive sampling, had a positive history of contact with a known COVID-19 patient and/or any two of the following signs and symptoms; fever, cough, malaise, body aches, arthralgia, new-onset loss of taste and smell, and dyspnea or oxygen saturation less than 85%. A detailed history was sought after informed consent and all these patients underwent non-contrast HRCT chest scans that were reported by an experienced consultant radiologist. The scans showing positive features for COVID-19 pneumonia were assessed for the nature and distribution of the disease. Results Amongst 48 suspects with negative RT-PCR assay, 38 (79.2%) showed ground-glass opacities, a hallmark feature of COVID-19 pneumonia. A total of 22 (57.89%) of these 38 patients had ground-glass opacities with a crazy-paving pattern, nine (23.68%) mixed ground-glass opacities with consolidation, and seven (18.42%) had pure ground-glass opacities. Among these 79.2% suspects, ground-glass opacities were multifocal in 37 (97.37%), bilateral in 35 (92.10%), peripheral in 36 (94.74%), and dorsally located in 32 (81.6%) cases. Subpleural atelectatic bands were seen in 18 (47.36%) of these, bronchovascular markings were prominent in 15 (39.47%), and reverse halo sign was positive in nine (23.68%) cases. Out of the rest of the cases, three were diagnosed as interstitial lung disease, two as chronic lung disease, and one as active pulmonary tuberculosis. Conclusion The majority of clinically suspected cases for COVID-19 showed hallmark findings on non-contrast HRCT chest scans in keeping with coronavirus disease regardless of a negative RT-PCR assay.

COVID-19 and severe ENT infections in pediatric patients. IS there a relationship?

BACKGROUND: Preliminary evidence suggests that children are just as likely to become infected with SARS-CoV-2 as adults but are less prone to developing severe clinical conditions. However, there are pediatric inflammatory conditions that have also been encountered. The aim of this report is to determine whether there is a relationship between COVID-19 and severe infections in the ear, nose, throat, and deep cervical area (ENT) in pediatric populations. MATERIALS AND METHODS: A compilation was made of all the cases of ENT area infections in the pediatric population per month attended to at the Niño Jesús University Children's Hospital from January 2010 to June 2020. Endemic channels and dispersion analysis were designed to analyze the incidence presented in the year 2020, compared to what was expected based on historical data from 2010 to 2019. Then, an epidemiological interview was conducted of the close contacts of COVID-19 of the children who presented a severe ENT infection in 2020. Finally, a serological test of IgG antibodies was performed on all of them to find out if they had overcome the COVID- 19. RESULTS: 620 patients from 1022 were eligible for the study. We observed a significant outbreak in the incidence of complicated mastoiditis and deep cervical infections with complications in the year 2020 (13 patients) linked to the COVID-19 pandemic. From these patients, 54% had been confirmed or had high suspicion of close contact with COVID-19.15.4% of children were positive in serological tests for IgG antibodies. CONCLUSION: There has been a significant increase in mastoiditis and deep cervical infections with complications in the first four months of 2020, which constitutes an outbreak. A considerable number (54%) of these complicated infections were related to close contact with COVID-19. Still, only 15.4% were positive in serological tests for IgG antibodies, so we cannot establish a direct categorical relationship. The limitations in primary care due to a shortage of human resources in dealing with the pandemic's initial onslaught and changes in help-seeking behavior could explain increased complicated infections.

When Uncontrolled Diabetes Mellitus and Severe COVID-19 Converge: The Perfect Storm for Mucormycosis.

Mucormycosis (MCR) has been increasingly described in patients with coronavirus disease 2019 (COVID-19) but the epidemiological factors, presentation, diagnostic certainty, and outcome of such patients are not well described. We review the published COVID-19-associated mucormycosis (CAMCR) cases (total 41) to identify risk factors, clinical features, and outcomes. CAMCR was typically seen in patients with diabetes mellitus (DM) (94%) especially the ones with poorly controlled DM (67%) and severe or critical COVID-19 (95%). Its presentation was typical of MCR seen in diabetic patients (mostly rhino-orbital and rhino-orbital-cerebral presentation). In sharp contrast to reported COVID-associated aspergillosis (CAPA) cases, nearly all CAMCR infections were proven (93%). Treating physicians should have a high suspicion for CAMCR in patients with uncontrolled diabetes mellitus and severe COVID-19 presenting with rhino-orbital or rhino-cerebral syndromes. CAMR is the convergence of two storms, one of DM and the other of COVID-19.

Post COVID-19 tuberculosis: An emerging threat of pandemic.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) pandemic has hit the world hard. Millions of people have died due to the infection and several have suffered with what are now known as post COVID-19 squeal. Among these squeals one is immunosuppression which leaves patients prone to severe opportunistic infection. We here report a case of young female who was infected by COVID-19 and later developed cavitary pneumonia which upon investigation turned out to be due to mycobacterium tuberculosis.  Through this report we aim to highlight the importance of high index of suspicion for infection like Mycobacterium tuberculosis after COVID-19 infection which developed in a healthy immunocompetent patient.
