Background Scorpion sting is a common medical problem and major cause of mortality and morbidity in many countries. The symptoms of envenomation are more severe in the pediatric population. The clinical manifestations of scorpion envenomation appear by activation of sympathetic and parasympathetic nervous system. Envenomation can cause multiorgan dysfunction and death. Case Presentation and Findings In this case report, we present a pediatric patient from Adana, Southeast Anatolia, with severe scorpion envenomation with Leiurus abdullahbayrami which is an especially dangerous species for children. Severe systolic dysfunction was detected by echocardiography. Troponin I levels elevated significantly and rapidly responded to three doses of antivenom therapy. Conclusion Early echocardiographic examination is an important procedure for patients with scorpion envenomation. Troponin I is a significant parameter to monitor the degree of cardiac injury. Antivenom therapy is the only recommended specific therapy for children with severe scorpion envenomation due to Leiurus abdullahbayrami. Abnormal echocardiography findings may require repeated doses of scorpion antivenom.

Background: Aim was to study clinical, socio- demographic and laboratory profile and outcome in children with scorpion envenomation up to 12 years of age. This study conducted to provide better insights in to the socio-demographic, clinical, laboratory profile of scorpion envenomation in rural health setting in India.Methods: This was a hospital based, prospective observational study done in children up to 12 years of age admitted in a tertiary care centre between March 2018 to April 2020 with history of scorpion envenomation, presence of sting mark or scorpion seen in vicinity of child by parents or near family members. Unknown bites or stings and cases were the clinical manifestations are not compatible with scorpion sting were excluded.Results: During the study period, 28 children were admitted for scorpion sting. Maximum number of cases were noted in the age group of 3-6 years and there is equal distribution of cases among males and females .Majority of cases from rural areas, 46.42% of the cases had black scorpion sting, most of the stings occurred during evening time and spring season. The most common sting sites were the distal part of the extremities. Pain at the sting site and local swelling were the most common presenting symptoms. The common signs noted were tachycardia. The most common ECG changes were noted in the present study was sinus tachycardia (46.42%) fallowed by ST segment changes noted in 21.4% of children. Commonest complications noted myocarditis, pulmonary edema, myocardial dysfunction, peripheral circulatory failure. One patient died due to pulmonary edema. Majority of the cases recovered without any sequale.Conclusions: Scorpion envenomation is a preventable emergency among children and closely associated with environmental condition, socioeconomic status and child activities. Supervised outdoor play, early hospitalization, close monitoring of vitals and management of complications and supportive care may reduce the mortality and morbidity.

Abstract The novel coronavirus disease (COVID-19) outbreak, caused by SARS-CoV-2, represents the greatest medical challenge in decades. We provide a comprehensive review of the clinical course of COVID-19, its comorbidities, and mechanistic considerations for future therapies. While COVID-19 primarily affects the lungs, causing interstitial pneumonitis and severe acute respiratory distress syndrome (ARDS), it also affects multiple organs, particularly the cardiovascular system. Risk of severe infection and mortality increase with advancing age and male sex. Mortality is increased by comorbidities: cardiovascular disease, hypertension, diabetes, chronic pulmonary disease, and cancer. The most common complications include arrhythmia (atrial fibrillation, ventricular tachyarrhythmia, and ventricular fibrillation), cardiac injury [elevated highly sensitive troponin I (hs-cTnI) and creatine kinase (CK) levels], fulminant myocarditis, heart failure, pulmonary embolism, and disseminated intravascular coagulation (DIC). Mechanistically, SARS-CoV-2, following proteolytic cleavage of its S protein by a serine protease, binds to the transmembrane angiotensin-converting enzyme 2 (ACE2) —a homologue of ACE—to enter type 2 pneumocytes, macrophages, perivascular pericytes, and cardiomyocytes. This may lead to myocardial dysfunction and damage, endothelial dysfunction, microvascular dysfunction, plaque instability, and myocardial infarction (MI). While ACE2 is essential for viral invasion, there is no evidence that ACE inhibitors or angiotensin receptor blockers (ARBs) worsen prognosis. Hence, patients should not discontinue their use. Moreover, renin–angiotensin–aldosterone system (RAAS) inhibitors might be beneficial in COVID-19. Initial immune and inflammatory responses induce a severe cytokine storm [interleukin (IL)-6, IL-7, IL-22, IL-17, etc.] during the rapid progression phase of COVID-19. Early evaluation and continued monitoring of cardiac damage (cTnI and NT-proBNP) and coagulation (D-dimer) after hospitalization may identify patients with cardiac injury and predict COVID-19 complications. Preventive measures (social distancing and social isolation) also increase cardiovascular risk. Cardiovascular considerations of therapies currently used, including remdesivir, chloroquine, hydroxychloroquine, tocilizumab, ribavirin, interferons, and lopinavir/ritonavir, as well as experimental therapies, such as human recombinant ACE2 (rhACE2), are discussed.

Background: Coronavirus disease 2019 (COVID-19) is associated with cardiac injury and overt myocardial dysfunction. However, whether COVID-19 is associated with subclinical myocardial dysfunction is unknown. Methods: We evaluated patients hospitalized for COVID-19 referred for transthoracic echocardiography (TTE), between March 17 and May 22, 2020, with a left ventricular ejection fraction (LVEF) ≥ 50%. Controls in a 1:1 ratio were selected from patients receiving TTE during the same month. Global longitudinal strain (GLS) was used to assess the association of COVID-19 and subclinical myocardial disease. Results: Among 99 patients (49 cases, 50 controls), average GLS was significantly reduced in cases vs. controls (mean ± SD, -14.8 ± 4.0% vs. -21.1 ± 4.0%, p < 0.0001). A total of 82.8% of cases vs. 7.1% of controls had an average GLS below normal (> 18%; p < 0.0001), which persisted despite multivariable adjustment ( Table ). Among COVID-19 patients with a prior TTE, absolute average GLS decreased 3.2% (p = 0.008) despite no change in LVEF (p = 0.41). Average GLS was reduced in non-survivors compared with survivors (p = 0.04), though only septal wall thickness (p = 0.03) was associated with in-hospital mortality on multivariable analysis. Conclusions: Among hospitalized patients receiving TTE, COVID-19 is independently associated with subclinical left ventricular systolic dysfunction in the vast majority of patients, and subclinical LV dysfunction is associated with survival. The clinical implications of these findings should be evaluated in future longitudinal multicenter studies.

A 12-year-old boy was referred with acute asymmetric pulmonary edema (APE) four-hour after scorpion sting to Emergency department. On admission, the main clinical manifestations were: dyspnea, tachypnea, and tachycardia. Chest x-ray revealed APE predominantly on the right hemithorax. The patient was treated with oxygen, intravenous frusemide and digoxin and discharged on the sixth hospital day in a good condition. This case report emphasizes the occurrence of asymmetric pulmonary edema after severe scorpion envenomation within few hours immediately after the sting.

(1) Background: Myocardial dysfunction in patients with sepsis is not an uncommon phenomenon, yet reported results are conflicting and there is no objective definition. Measurement of troponin may reflect the state of the heart and may correlate with echocardiographically derived data. This study aimed to evaluate the role of admission and peak troponin-I testing for the identification of sepsis-induced myocardial dysfunction (SIMD) by transthoracic echocardiography (TTE). (2) Methods: This was a retrospective cohort study using a prospective registry of septic shock at an Emergency Department from January 2011 and April 2017. All 1,776 consecutive adult septic shock patients treated with protocol-driven resuscitation bundle therapy and tested troponin-I were enrolled. SIMD was defined as left ventricular (LV) systolic/diastolic dysfunction, right ventricular (RV) diastolic dysfunction, or global/regional wall motion abnormalities (WMA). (3) Results: Of 660 (38.4%) septic shock patients with an elevated hs-TnI (≥0.04 ng/mL) at admission, 397 patients underwent TTE and 258 cases (65%) showed SIMD (LV systolic dysfunction (n = 163, 63.2%), LV diastolic dysfunction (n = 104, 40.3%), RV dysfunction (n = 97, 37.6%), and WMA (n = 186, 72.1%)). In multivariate analysis, peak hs-TnI (odds ratio 1.03, 95% confidence interval 1.01–1.06, p = 0.008) and ST-T wave changes in the electrocardiogram (odds ratio 1.82, 95% confidence interval 1.04–2.39, p = 0.013) were associated with SIMD, in contrast to hs-TnI level at admission. The area under the curve of peak hs-TnI was 0.668. When the peak hs-TnI cutoff value was 0.634 ng/mL, the sensitivity and specificity for SIMD were 58.6% and 59.1%, respectively. 4) Conclusions: About two-thirds of patients with an elevated hs-TnI level have various cardiac dysfunctions in terms of TTE. Rather than the initial level, the peak hs-TnI and ST-T change may be considered as a risk factor of SIMD.

Aluminium phosphide (ALP) is widely used as a fumigant pesticide. In case of ALP poisoning, it is responsible for myocardial dysfunction, related to toxic myocarditis, and hemodynamic disorders. We report a case of a 28-year-old female who had intentionally ingested ALP and was admitted with cardiogenic shock. The transthoracic echocardiography (TTE) at the time of admission showed severe global myocardial hypokinesia with the presence of a giant left ventricular thrombus. Cardiovascular magnetic resonance (CMR) revealed extensive toxic myocarditis with a left ventricular systolic dysfunction. All cardiac lesions were reversible after symptomatic treatment, within 6 months. We aim, by reporting this case, to evidence the complete reversibility of cardiac injury due to aluminium phosphide poisoning documented by transthoracic echocardiography and cardiovascular magnetic resonance.

Background. Obesity is a risk factor for cardiovascular disease. Increasing evidence suggests that reduced levels of the adipocyte-derived plasma protein adiponectin are associated with an increased cardiovascular risk. Here, we examined the effects of adiponectin on lipopolysaccharide- (LPS-) induced acute cardiac injuryin vivo.Methods and Results. A single dose of LPS (10 mg/kg) was intraperitoneally injected into wild-type (WT) and adiponectin-knockout (APN-KO) mice. Following LPS administration, APN-KO mice had exacerbation of left ventricular (LV) systolic dysfunction compared with WT mice. Administration of LPS to WT and APN-KO mice led to an increased expression of inflammatory cytokines including TNF-αand IL-6 in the heart, but the magnitude of this induction was greater in APN-KO mice compared to WT mice. Systemic delivery of an adenoviral vector expressing adiponectin (Ad-APN) improved LPS-induced LV dysfunction in APN-KO mice, and this effect was accompanied by the reduced expression of TNF-αand IL-6 in the heart. Administration of etanercept, a soluble TNF receptor abolished the reduced LV contractile function in response to LPS in APN-KO mice.Conclusion. These results suggest that adiponectin protects against LPS-induced acute cardiac injury by suppressing cardiac inflammatory responses, and could represent a potential therapeutic target in sepsis-associated myocardial dysfunction.

ObjectiveSepsis-induced myocardial dysfunction (SIMD) can involve both the left and right ventricles. However, the characteristics and outcomes across various manifestations of SIMD remain unknown.MethodsThis was a retrospective cohort study using a prospective registry of septic shock from January 2011 and April 2017. Patients with clinically presumed cardiac dysfunction underwent echocardiography within 72 hours after admission and were enrolled (n=778). SIMD was classified as left ventricle (LV) systolic/diastolic and right ventricle (RV) dysfunction, which were defined based on the American Society of Echocardiography criteria. The primary outcome was 28-day mortality.ResultsOf the 778 septic shock patients who underwent echocardiography, 270 (34.7%) showed SIMD. The median age was 67.0 years old, and the male was predominant (57.3%). Among them, 67.3% had LV systolic dysfunction, 40.7% had RV dysfunction and 39.3% had LV diastolic dysfunction. Although serum lactate level and sequential organ failure assessment score were not significantly different between groups, SIMD group showed higher troponin I (0.1 vs 0.1 ng/mL; p=0.02) and poor clinical outcomes, including higher 28-day mortality (35.9 vs 26.8%; p<0.01), longer intensive care unit length of stay (5 vs 2 days; p<0.01) and prolonged mechanical ventilation (9 vs 4 days; p<0.01). Multivariate analysis showed that isolated RV dysfunction was an independent risk factor of 28-day mortality (OR 2.26, 95% CI 1.04 to 4.91).ConclusionsOne-third of patients with septic shock showed various myocardial dysfunctions. LV systolic dysfunction was common; however, only RV dysfunction was associated with short-term mortality.

Aims and Objectives: To study an incidence of myocardial dysfunction in neonates admitted with perinatal asphyxia, to find out its correlation with severity of birth asphyxia and its outcome. Methods: This prospective study was conducted among 40 term neonates admitted in NICU of Civil Hospital Ahmedabad who had suffered with perinatal asphyxia (defined by WHO ), resuscitated as per NRP guidelines-2015 including both intramural and extramural admissions and who developed to hypoxic ischemic encephalopathy as defined by Levene staging. Neonates with congenital heart diseases, major central nervous system malformations and neonatal sepsis were excluded. Myocardial involvement was assessed by clinical evaluation, ECG, Creatinine Kinase Total (25-200IU/L), CK-MB (0-25IU/L) and Troponin I (0-0.03ug/L) measurements. Results: Among 40 cases, 10(25%) neonates had moderate birth asphyxia while 30(75%) had severe birth asphyxia. Respiratory distress was observed in 34(77.5%), poor spontaneous respiration 4(10%),shock in 14(35%),CCF 19(47.5%) while ECG was abnormal in 30(76.7%). Serum levels of CPK Total, CPK- MB and Troponin I were raised in 34(85%), 32(80%) and 28 (70%) neonates, respectively.  Conclusion: There was a direct correlation between ECG changes and enzymatic levels which showed increasing abnormalities with increasing with severity of HIE.

Abstract Scorpion envenomation is a leading cause of morbidity and mortality among accidents caused by venomous animals. Major clinical manifestations that precede death after scorpion envenomation include heart failure and pulmonary edema. Here, we demonstrate that cardiac dysfunction and fatal outcomes caused by lethal scorpion envenomation in mice are mediated by a neuro-immune interaction linking IL-1 receptor signaling, prostaglandin E2, and acetylcholine release. IL-1R deficiency, the treatment with a high dose of dexamethasone or blockage of parasympathetic signaling using atropine or vagotomy, abolished heart failure and mortality of envenomed mice. Therefore, we propose the use of dexamethasone administration very early after envenomation, even before antiserum, to inhibit the production of inflammatory mediators and acetylcholine release, and to reduce the risk of death.
