Short-term azithromycin use is associated with QTc interval prolongation in children with cystic fibrosis. Arch Pediatr 2024:S0929-693X(24)00060-5. [PMID: 38637249 DOI: 10.1016/j.arcped.2024.02.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 02/07/2024] [Accepted: 02/17/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND Azithromycin is used for children with cystic fibrosis (CF) for its immunomodulatory and anti-inflammatory action. This study investigated the short-term alterations in QTc interval associated with azithromycin prophylaxis in pediatric patients with CF. METHODS This study included 121 patients with mild CF, of whom 76 received azithromycin (patient group) and 45 did not receive azithromycin (control group). The patient and control groups were categorized according to age as under 12 years of age and over 12 years of age. The first presentation measured all the patient and control groups at basic QTc time intervals. The QTc intervals of all patients were then remeasured systemically at 1, 3, and 6 months. Age categories and QTc intervals that were calculated at each month in the patient and control groups were compared statistically. RESULTS A statistically significant difference was detected in the patient group between the initial QTc interval time and the electrocardiogram (ECG) findings in the first and third months after prophylaxis treatment (p < 0.001; p = 0.01). However, no statistically significant difference was detected in the sixth month (p > 0.05) in all groups. Almost all of the children's QTc intervals were within normal range and within the safety zone (under 0.44 s). No statistically significant difference was detected in the control group between the initial ECG and the QTc intervals measured at 1, 3, and 6 months. CONCLUSION Short-term use of azithromycin prophylaxis in pediatric patients with mild CF slightly increased the QTc interval in the first and third months of follow-up. Nevertheless, all QTc interval changes fell within the safety zone. Notably, 1 month of follow-up treatment should be performed to check for any alteration in the QTc interval. If increased QTc interval duration is not detected in the first month, azithromycin prophylaxis can be safely prescribed.

Abstract
BACKGROUND Isolated agenesis of ductus venosus (ADV) is usually a benign condition, but it may be associated with cardiovascular defects, hydrops, growth restriction, and chromosomal abnormalities. Additionally, persistent left superior vena cava (PLSVC) and bovine aortic arch are relatively common fetal anomalies. To the author's knowledge, this is the first report of prenatal detection of DV agenesis and PLSVC associated with the postnatal bovine aortic arch with a hypoplastic transverse aortic arch. CASE A 25-year-old, G2P1 woman was referred to our department at 31 weeks due to fetal growth restriction and short femur. On fetal echocardiography, DV could not be viewed via two-dimensional (2D) and Doppler ultrasound (US) imaging; there was also evidence of the co-occurrence of PLSVC and an aortic arch anomaly. We revealed the intrahepatic continuation of the umbilical vein. A weekly follow-up program was scheduled for the patient and the rest of the pregnancy was uneventful. Postnatal, thorax computer tomography and transthoracic echocardiography (TTE) demonstrated PLSVC and bovine aortic arch associated with hypoplastic transverse aortic arch. Routine echocardiographic examinations revealed that the blood flow of the aortic arch had increased gradually, and the male infant's aortic arch had significantly widened and reached the normal range until the baby was discharged from the hospital. CONCLUSION DV agenesis and PLSVC are usually benign conditions but underlying serious heart diseases may accompany them. Therefore, in situations like ours, a prenatal aortic arch evaluation is of capital importance. Postnatal hemodynamic changes should be taken into consideration in the management of these cases. This is the first example in the literature that these abnormalities co-existed in one case.

Abstract
AIM This study aimed to assess the effect of tobacco exposure on maternal thyroid function and investigate its relationship to subclinical hypothyroidism in pregnant women during the first trimester. SUBJECTS AND METHOD A comparison of maternal thyroid function was made on 45 smokers, who composed the study group, and 72 non-smokers, pregnant women, who constituted the control group. After determining smokers by questionnaire, carbon monoxide (CO) levels in the expiratory air of the participants in both groups were measured and recorded, and the smokers' exposure was objectively confirmed. RESULTS Smoking and non-smoking pregnant women were similar regarding body mass index (BMI). While the TSH and fT4 levels were respectively 1.48 mlU/L and 11.43 pmol/L in pregnant women who smoked, that ratio changed to 1.72 mlU/L and 11.17 pmol/L in the non-smokers' group. But the differences between the groups were not statistically significant (p=0.239, p=0.179). Even though the rate of subclinical hypothyroidism was 8.9% in the smoking group, it was approximately 19.4% in the non-smoker group; the difference was not statistically significant (p=0.187). CONCLUSION This study proved that there is no statistically significant difference between maternal serum TSH and fT4 levels and the rate of subclinical hypothyroidism in smokers during pregnancy in the first trimester.

Abstract
BACKGROUND This study aimed to assess the ventricular anatomy, function of the right ventricle, and the haemodynamic findings of pulmonary artery in children with cystic fibrosis using cardiac MRI. PATIENTS This prospective study consisted of 32 children with mild cystic fibrosis and 30 age-matched healthy control participants. METHODS Cardiac MRI was used to assess right ventricular volumes, anatomy, and function and to assessment of haemodynamic findings of pulmonary artery in the control and study groups. Haemodynamic findings of pulmonary arteries were determined using pulmonary arteries peak velocity (cm/s), and pulmonary arteries time-to-peak velocity (ms) and pulmonary artery systolic pressure. All data of children with mild cystic fibrosis were compared with those of 30 age-matched healthy control group participants. RESULTS Our patients and their age-matched controls were aged from 6 to 17 years and from 7 to 15 years, respectively. We found that ejection fraction (%), cardiac output (L/ml), cardiac output (L/ml/m2), and systolic volume (ml/m2) were significantly lower in children with cystic fibrosis (p < 0.01). Right ventricular anterior wall thickness (mm) was significantly higher in children with cystic fibrosis (p = 0.01). No significant difference was observed between the haemodynamic parameters of pulmonary artery in the patient group. CONCLUSION In our study, cardiac MRI was used to investigate whether the right ventricle was affected functionally and anatomically in children with mild cystic fibrosis. We detected a significant decrease in right ventricular systolic functions and notable alterations in the right ventricular geometry of children with mild cystic fibrosis. These alterations usually manifest themselves as hypertrophy of the right ventricle. Our study's results demonstrate no relationship between the development of pulmonary hypertension in mild cystic fibrosis children.

Abstract
BACKGROUND Acute rheumatic fever (ARF) is a multisystemic inflammatory disease in children and young adults. The most notable complications of ARF are rheumatic heart disease (RHD) and Sydenham's chorea (SC). There have been many reports about executive dysfunctions with children who have SC. "Executive function" is an umbrella term that is used to describe higher level cognitive functions. The aim of this study is to determine the executive functions of children with RHD. We evaluated executive functions in healthy children with the same sociodemographic characteristics as children with RHD. METHODS Our study was designed as a cross-sectional randomized study, including children with RHD aged between 12 and 18, and healthy controls. The difference between the patient and control group participants in terms of age, gender, education level, education level of the parents, family income level, and executive functions were investigated. Executive functions composed of Digit Sequence Test, Verbal Fluency Test, Trail-Making Test, Stroop Test, Wisconsin Card Sorting Test. RESULTS In our study, a total of 30 children with RHD were followed up at the pediatric cardiology outpatient clinic of Bezmialem Vakif University Hospital composed the patient group. The control group was made up of 30 healthy children of the same sex and age group as the patient group. The mean age of the case group was 14.73 ± 1.84 years. The Digit Span Test, Verbal Fluency Test, Trail-Making Test, Wisconsin Card Sorting Test, and Stroop Test produced no statistically significant differences between the RHD patients and the controls. CONCLUSIONS No statistically significant difference was found between the RHD patients and control patients in any executive function test. It was suggested that executive dysfunction might not develop in RHD patients before developing SC.

Abstract
BACKGROUND Research into new markers has been intensified for early diagnosis, prognosis, and differentiation of SIRS, sepsis, and septic shock in recent years. This study aimed to investigate the role of soluble triggering receptor expressed in myeloid cells-1 (sTREM-1) and interleukin (IL)-6 in distinguishing between systemic inflammatory response syndrome (SIRS), sepsis, and septic shock in pediatric intensive care unit (PICU) patients. METHODS Between June 2014 and July 2015, 90 consecutive patients who were treated in the PICU were included in this prospective observational study. Patients were divided into four groups: control (n = 23), SIRS (n = 22), sepsis (n = 23), and septic shock (n = 22). All patients were evaluated for white blood cell (WBC), serum C-reactive protein (CRP), procalcitonin (PCT), IL-6, and sTREM-1 levels at 0, 24, and 72 h of admission. The prognostic evaluations were made using the Pediatric Risk of Mortality III (PRISM III) and Pediatric Logistic Organ Dysfunction (PELOD) scores. Patients were evaluated in terms of age, gender, prognosis, pathogen growth in culture, PRISM III and PELOD score, WBC, CRP, PCT, IL-6, and sTREM-1 levels and a comparison was made between groups. RESULTS There was no significant difference between all groups in terms of the 0-, 24-, and 72-h sTREM-1 values (p = 0.761, p = 0.360, and p = 0.822, respectively). CRP and PCT values did not differ between the septic shock, sepsis, and SIRS groups at 0, 24, and 72 h. In the septic shock group, the 0-h IL-6 value was significantly higher than that of the SIRS group (p = 0.025). The 24-h IL-6 value in the septic shock group was significantly higher than the values of the sepsis and SIRS groups (p = 0.048 and p = 0.043, respectively). No significant difference was detected between the septic shock, sepsis, and SIRS groups in terms of IL-6 values at 72 h. CONCLUSION sTREM-1 is not useful for the diagnosis of infection and for distinguishing between sepsis, septic shock, and SIRS since it does not offer a clear diagnostic value for PICU patients, unlike other reliable markers such as WBC, CRP, and PCT. Elevated IL-6 levels may indicate septic shock in PICU patients. More research on sTREM-1 is needed in this setting.

Abstract
BACKGROUND Tuberous sclerosis (TS) is an autosomal dominant and hereditary disorder. Cardiac rhabdomyoma and arrhythmias are the most deleterious risk factors linked to TS. Although arrhythmias in pediatric patients with TS who have cardiac rhabdomyoma have been frequently reported, arrhythmia in patients who have TS without rhabdomyoma is rarely reported in the literature. The study aimed to assess the susceptibility of pediatric patients who have TS without cardiac rhabdomyoma to cardiac arrhythmia using electrocardiographic (ECG) markers. METHODS This prospective study included 10 patients who had TS without cardiac rhabdomyoma. The control group was made up of 30 healthy children of the same age and sex as the patient group. P wave, P wave dispersion, QT dispersion, QTc dispersion, TP-e interval, and TP-e interval dispersion were calculated on 12-lead surface ECGs for each patient in both groups and compared. RESULTS P wave, P wave dispersion, QT dispersion, and QTc dispersion were found to be significantly higher in the patient group (P<0.001). Furthermore, patients had a greater Tp-e interval and Tp-e interval dispersion than healthy children (P<0.001). CONCLUSION Pediatric patients with TS without cardiac rhabdomyoma might be prone to atrial and ventricular arrhythmias according to their prolonged ECG markers. Our findings suggest that patients with TS without cardiac rhabdomyoma need close monitoring for atrial and ventricular arrhythmias.

Abstract
BACKGROUND Cystic fibrosis (CF) is a multisystemic disease that prevalently involves the lungs. Hypoxemia occurs due to the existing of progressive damage to the pulmonary parenchyma and pulmonary vessels. The condition may cause systolic and diastolic dysfunction to the right ventricle due to the effects of high pulmonary artery systolic pressure (PASP). The study aimed to determine echocardiographic alterations in PASP, right ventricle (RV) anatomy, and functions in mild CF children. MATERIALS AND METHODS RV anatomy, systolic, and diastolic functions were evaluated with conventional echocardiographic measurements. Estimated PASP was used measured with new echocardiographic modalities, including pulmonary artery acceleration time (PAAT), right ventricular ejection time (RVET), and their ratio (PAAT/RVET). The obtained echocardiographic data were statistically compared between the patient group and the control group. RESULTS The study consisted of 30 pediatric patients with mild CF and 30 healthy children with similar demographics. In patient group, conventional parameters disclosed differences in RV anatomy, both systolic and diastolic functions of RV compared with the healthy group. We did not compare the patient group with published standard data because of the wide range variability. However, new echocardiographic parameters showed notable increase in pulmonary artery pressure compared with values of control group and published standard data (p<0.001). CONCLUSION Elevated PASP, RV failure, and Cor pulmonale usually begin early in children with mild CF. In addition to routine echocardiographic measurements to evaluate RV, we recommend the use of new echocardiographic modalities for routine examinations and in the follow up of children with mild CF.

Abstract
Brucellosis is one of the most common zoonosis worldwide. It is still endemic in many regions of the world. A 6-year-old female was admitted to the emergency department (ED) due to a sudden change in consciousness, urinary incontinence, vomiting, and difficulty in walking. Neurological examination demonstrated abducens nerve paralysis, mild-to-moderate motor deficit in hemiparesis in the left arm. Brain magnetic resonance imaging showed a hemorrhagic focus at the right frontal lobe and thrombosis in the superior sagittal sinus of the brain. The diagnosis of neurobrucellosis was confirmed by identifying Brucella spp. in the blood culture on the day 6 of pediatric intensive care unit admission; thus, trimethoprim-sulfamethoxazole and rifampicin, and ceftriaxone were promptly initiated. Despite neuroprotective management and acetazolamide, the patient's neurological problems and high intracranial pressure (ICP) persisted. An external ventricular drainage tube and a Codman ICP monitor were placed to be on the consent vigilance of the patient's neurological condition. The patient's ICP continued to increase despite the current treatment regimen; therefore, a decompressive bitemporal craniectomy was performed. The ICP level of the patient returned to its normal range immediately after the craniectomy. The patient did not have any notable neurologic sequelae at the first-year follow-up. Neurobrucellosis is a rare complication of systemic brucellosis and may present as meningitis, encephalitis, myelitis, radiculitis, and/or neuritis. Herein, we describe a six-year-old girl with brucellosis complicated with cerebral vein thrombosis. This case illustrates the need for close monitoring of patients with unexplained neurological signs or symptoms for brucellosis in endemic areas.

Abstract
AIM Reports describing coronavirus disease 2019 (Covid-19) in children are fewer than adult studies due to milder clinical picture. We aimed to share our experience at a single center with an emphasis on collective decision making. MATERIALS AND METHODS A suspected case was defined as the presence of symptoms suggestive of COVID-19 and/or positive contact history. SARS-CoV-2 PCR positive patients were defined as confirmed COVID-19. Between March 12, 2020, and May 15, 2020, all children presenting with fever, cough, or respiratory difficulty were investigated for COVID-19. A total of 719 children were examined at outpatient clinics, and 495 were tested with polymerase chain reaction (PCR) for suspicion of COVID-19. A team was organized for monitoring and treating patients either as outpatients or hospitalization. Patients were evaluated in terms of age, gender, travel history, epidemiological history, clinical symptoms and signs, laboratory and radiological findings, treatment, and outcome. RESULTS Sixty patients were hospitalized for suspicion of COVID-19. Forty-three patients were diagnosed as probable or confirmed COVID-19. 21 of 43 patients (48.8%) were PCR confirmed. The remaining 22 were diagnosed by epidemiologic history, clinical assessment, and computerized thorax tomography (CT) findings. The median age was 126 and 78.5 months in PCR positives and PCR negatives, respectively and the youngest patient was a 28 days old baby. Nineteen of the patients had an upper respiratory infection (44.1%). Although five patients had no clinical signs, chest X-ray, or CT revealed pneumonia. CONCLUSIONS As previously reported, the clinical manifestations of COVID-19 in children are mostly mild. Even very young kids can become infected following exposure to sick family members. International and local guidelines are valuable for decision making since it is a new disease. A combination of chest disease, infectious diseases, and emergency care physicians approach will aid the appropriate management of cases.

Abstract
AbstractSudden cardiac arrest (SCA) is the sudden cessation of regular cardiac activity so that the victim becomes unresponsive, with no signs of circulation and no normal breathing. Asystole, ventricular tachycardia (VT), ventricular fibrillation (VF), and pulseless electrical activity are the underlying rhythm disturbances in the pediatric age group. If appropriate interventions (cardiopulmonary resuscitation-CPR and/or defibrillation or cardioversion) are not performed rapidly, this condition progresses to sudden death. There have not been many reported cases of the approach and treatment of cardiac arrhythmias after SCA. Herein, we would like to report a case of a 15-year-old female patient with dilated cardiomyopathy (DCM) who was admitted to our clinic a year ago, and while her left ventricular systolic functions were improved, SCA suddenly occurred. Since the SCA event occurred in another city, intravenous treatment of amiodarone was done immediately and was switch to continuous infusion dose of amiodarone until the patient arrived at our institution's pediatric intensive care unit (PICU) 3 hours later. During the patient's 20-day PICU hospitalization, she developed pulseless VT and VF from time to time. The patient's pulseless VT and VF attacks were brought under control by the use of a defibrillator and added antiarrhythmic drugs (amiodarone, flecainide, esmolol, and propafenone). Intriguingly, therapy-resistance bigeminy with premature ventricular contractions (PVCs) continued despite all these treatments. The patient did not have adequate blood pressure measured by invasive arterial blood pressure monitoring while having bigeminy PVCs. The intermittent bigeminy PVCs ameliorated rapidly after intermittent boluses of lidocaine. In the end, multiple antiarrhythmic therapies and intermittent bolus lidocaine doses were enough to bring her cardiac arrhythmias after SCA under control. This case illustrates that malign PVC's should be taken very seriously, since they may predispose to the development of VT or VF. Also, this case highlights the importance of close vigilance of arterial pressure tracings of patients with bigeminy PVCs which develop after SCA and should not be accepted as normal.

Abstract
Cardiovascular involvement is uncommon in pediatric patients with hemolytic uremic syndrome associated with Shiga toxin-producing Escherichia coli (STEC-HUS). In this case report we presented a case of 17-month-old toddler who had a sporadic type of STEC-HUS complicated by acute myocarditis. The patient was successfully treated by a single dose of eculizumab after six doses of therapeutic plasma exchange (TPE) were inefficient to prevent the cardiac complication. Hepatotoxicity was observed after a single dose of eculizumab. Hepatic and cholestatic enzyme levels slowly returned to normal within 6 months. To the best of our knowledge, this is the first case of myocarditis/cardiomyopathy treated with eculizumab in STEC-HUS. This case illustrates the need for vigilance regarding myocardial involvement and eculizumab-induced hepatotoxicity in STEC-HUS.

Short-term efficacy of ORS formulation and propranolol regimen in children with POTS. Arch Pediatr 2020; 27:328-332. [PMID: 32651146 DOI: 10.1016/j.arcped.2020.06.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 04/09/2020] [Accepted: 06/01/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND To evaluate the short-term effectiveness of reduced-osmolarity oral rehydration salt formulation (ORS) and propranolol in children diagnosed with postural orthostatic tachycardia syndrome (POTS) in head-up tilt testing (HUTT). METHODS Children were admitted with symptoms of orthostatic intolerance (OI) occurring in a standing position and disappearing in the supine position. Patients with heart rate increments of ≥40bpm and symptoms of OI constituted the pediatric POTS group in HUTT. A total of 70 pediatric patients with POTS were included in the study. POTS patients were divided into two groups based on whether they were prescribed reduced-osmolarity ORS and propranolol or not. The study group comprised patients on a regimen of reduced-osmolarity ORS and propranolol (n=34), while the control group comprised patients who were not prescribed any medication (n=36). The frequency of symptoms and standardized symptom scores were analyzed before and after 3 months of treatment in both groups. RESULTS The post-treatment frequency of syncopal attacks was significantly reduced in both groups (P<0.01 for both groups), but the post-treatment standardized symptom scores were significantly reduced in the pediatric study group compared with the control group (P<0.01). CONCLUSION The frequency of syncopal attacks was significantly reduced and the symptom scores for OI were improved in the study group. The improvement in OI symptom scores was better in the treatment group than in the control group. The control group symptoms persisted and caused extreme difficulty in their daily activities. In view of its clinical efficacy, we strongly advocate the use of combined treatment of reduced-osmolarity ORS and low-dose propranolol in pediatric patients with POTS.

Lifesaving Treatment of Aortic Valve Staphylococcus aureus Endocarditis: Daptomycin and Early Surgical Therapy. J Pediatr Intensive Care 2020; 10:298-302. [PMID: 34745704 DOI: 10.1055/s-0040-1713614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 05/13/2020] [Indexed: 10/23/2022] Open
Abstract
Infective endocarditis (IE) is an uncommon infection in children. The recommended treatment for native valve endocarditis secondary to methicillin-susceptible Staphylococcus aureus infection is antistaphylococcal penicillins such as nafcillin or oxacillin. If the initial therapy fails in IE, it can lead to catastrophic results. Nowadays, daptomycin is the best alternative antimicrobial agent to treat children with severe infections, when standard antimicrobial therapy does not yield a result. Herein, in this article, we described a case of a 16-year-old boy who had aortic valve S. aureus endocarditis with septic embolization and stroke. The patient was successfully treated only with daptomycin as well as surgical therapy in the early phase of the infection.

Abstract
Double aortic arch (DAA) is a common form of complete vascular ring. The condition leads to airway obstruction and compression of the esophagus. A balanced type of DAA is an extremely rare anomaly. The anatomical aberration cannot be easily distinguished by transthoracic echocardiography when an infant has chronic respiratory distress. Herein we presented a case of an 11-month-old infant who had chronic respiratory distress and a balanced type of DAA.

Abstract
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) accounts for 0.023% of all cases reported in pediatric patients. According to literature, only a handful of ALCAPA patients are able to reach adulthood. Clinical manifestations of ALCAPA range from fatigue during exercise to sudden death in adulthood. Herein, we described a 12-year-old symptomatic patient with ALCAPA who had severe chest pain after using salbutamol treatment for presumed asthma. ALCAPA is one of the curable versions of myocardial ischemia and infarction in childhood. Due to clinical findings in conjunction with electrocardiogram and echocardiography, a computed tomography scan with coronary angiography was performed and the diagnosis of ALCAPA was confirmed. We presented this case because ALCAPA-related myocardial ischemia and infarction in children are rare with only sporadic cases reported. This case illustrated the need for close monitoring and surgery as the best treatment for ALCAPA associated with myocardial infarction.

Sudden Cardiac Arrest and Malignant Ventricular Tachycardia in an 8-Year-Old Pediatric Patient Who Has Hemolytic Uremic Syndrome Associated with Shiga Toxin-Producing Escherichia coli. J Pediatr Intensive Care 2020; 9:290-294.

Abstract
Gastrointestinal, neurological, pancreatic, hepatic, and cardiac dysfunction are extrarenal manifestations of hemolytic uremic syndrome associated with Shiga toxin-producing Escherichia coli (STEC-HUS). The most frequent cause of death for STEC-HUS is related to the central nervous system and cardiovascular system. Cardiac-origin deaths are predominantly related to thrombotic microangiopathy-induced ischemia and the immediate development of circulatory collapse. STEC-HUS cardiac related deaths in children are rare with only sporadic cases reported. In our literature search, we did not come across any pediatric case report about STEC-HUS causing sudden cardiac arrest and malignant ventricular tachycardia (VT). Herein, we report the case of an 8-year-old female child with a typical clinical manifestation of STEC-HUS. On the seventh day of pediatric intensive care unit admission, the patient had a sudden cardiac arrest, requiring resuscitation for 10 minutes. The patient had return of spontaneous circulation with severe monomorphic pulsed malignant VT. Intravenous treatment with lidocaine, amiodarone and magnesium sulfate were promptly initiated, and we administered multiple synchronized cardioversions, but VT persisted. Furthermore, we were not able to ameliorate her refractory circulation insufficiency by advanced cardiopulmonary resuscitation. Thus, inevitably, the patient lost her life. This case illustrates the need for aggressive management and the dilemma that pediatric critical care specialists, cardiologists, and nephrologists have to face when dealing with STEC-HUS that is worsened by a sudden cardiac arrest accompanied with VT.

Double Aortic Arch Mimics the Clinical Characteristics of Severe Reactive Airway Disease in a Pediatric Patient. J Pediatr Intensive Care 2020; 9:141-144.

Abstract
Reactive airway disease is a prevalent condition that can be detected in the early infancy period. The condition might also deteriorate into asthma in some cases. If infants do not respond to the treatment of persistent wheeze and coughing, other rare causes should be investigated. The complete form of vascular ring is an extremely uncommon congenital cardiovascular abnormality. Double aortic arch constitutes the most significant portion of the complete vascular ring anomalies. Clinical manifestations of the anomaly are mainly respiratory due to the tracheal compression and mimicking the conditions of asthma. There have not been many reports about the clinical presentations of double aortic arch being remarkably similar to the same clinical manifestations of asthma in the literature. As far as we can be sure, there have not been any reported cases about severe reactive airway disease that caused a patient to have a life-threatening condition in the pediatric intensive care unit. Herein, we present a 5-month-old girl who had double aortic arch. Her anatomical aberration was diagnosed by three-dimensional computed tomography angiography of thorax, and the anomaly mimicked the clinical characteristics of life-threatening severe reactive airway disease.

Abstract
Cardiogenic pulmonary edema (CPE) is a rare clinical condition of acute rheumatic fever (ARF) in the early stage. Generally, CPE can be convalesced by steroid and anticongestive treatment. Herein, we describe a case of a 14-year-old boy with ARF presenting with bilateral pulmonary edema secondary to acute mitral and aortic insufficiency. In this case, the pulmonary edema of ARF was successfully managed by combined surgical replacements of both valves.

Abstract
We report a 13-year-old boy who (initially) had symptoms of toxic shock-like syndrome and mumps. Then, the patient was hospitalized in the pediatric intensive care unit (PICU) because of his ongoing hemodynamic instability (low blood pressure of 70/30 mm Hg and capillary refill time of > 4 seconds). During his stay in the PICU, the patient was treated with fluid resuscitation and vasoactive infusion and at the same time was diagnosed with Kawasaki disease shock syndrome (KDSS), when giant right coronary artery aneurysms were detected on echocardiographic examination. This case illustrates the risk of KDSS in patient who carries both parotitis and toxic shock-like syndrome. The clinicians should be cautious about detecting any types of coronary artery aneurysms in such patients. This is the first case of KDSS associated with parotitis reported in the literature.
