SARS-CoV-2 infection showing signs of cerebral sinus vein thrombosis in the infantile period.

The clinical manifestations of SARS-CoV-2 infection mainly involve the respiratory system. However, there is increasing evidence that this virus can affect other organs, causing a wide range of clinical symptoms. This is the report of a 40-day-old patient who presented with sepsis and had no risk factors other than SARS-CoV-2 infection, whose radiological findings were compatible with cerebral sinus vein thrombosis.

An indirect effect of COVID-19 pandemic: Increased pediatric perforated appendicitis rate due to delayed admission.

Objectives: Appendicitis is a common surgical emergency among children. The coronavirus pandemic affected the system of hospitals more than any other field, and great amount of people were concerned about visiting the hospitals for any reason. In this study, it was aimed to evaluate the profile of appendicitis by emphasizing perforated and acute appendicitis in the pandemic period and to compare the rates with previous three years. Material and Methods: Charts of the children who underwent laparoscopic appendectomy due to appendicitis between March 11-September 30 between 2017-2020 were retrospectively analyzed in terms of demographic data, duration of symptoms, duration between hospital admission and surgery, radiologic imaging and perioperative outcomes. Results: This study includes 467 children who underwent laparoscopic appendectomy. There were 97 procedures in 2020, 111 in 2019, 146 in 2018 and 113 in 2017. Multiple comparison tests revealed that age did not show difference; but onset of symptoms in admission (p= 0.004), hospitalization time before surgery (p <0.001), total hospitalization time (p <0.001) showed statistically significant difference between years. Pairwise comparisons showed that these parameters were increased in 2020 compared to other years. Perforated appendicitis rate was significantly increased in 2020 when compared to previous years. Conclusion: Although there is no direct relation between appendicitis and COVID-19 infection in the current knowledge, perforated appendicitis was found to be increased in children during the COVID pandemic. Reason of the higher rate of perforated appendicitis may be multifactorial; however, the pandemic appears to have a role in increased morbidity in children with appendicitis indirectly due to delay of hospital admissions.

The role and efficacy of routine high-sensitivity troponin T screening in paediatric COVID-19.

OBJECTIVE: We aimed to evaluate the efficacy and role of high-sensitivity troponin T in children with a confirmed SARS-CoV-2 infection and also the correlation of troponin T levels with symptoms, and echocardiographic findings were analysed. METHODS: Two hundred and fourteen patients with a confirmed SARS-CoV-2 infection between the dates of 28 March and 15 August 12020 were enrolled in this retrospective single-centre study. Patients with comorbidities and diagnosed as multisystem inflammatory syndrome in children were excluded. Demographic data, clinical and laboratory parameters were evaluated. The patients were classified and compared according to the troponin positivity. The correlation of troponin T with symptoms and echocardiographic findings was analysed. RESULTS: The most common symptoms in the whole study group were fever (53.3%) and cough (24.8%). Troponin T levels were elevated in 15 (7%) patients. The most common symptom in patients with troponin positivity was also fever (73.3%). Troponin T positivity was significantly higher in patients under the age of 12 months and troponin T levels were negatively correlated with age. C-reactive protein levels were elevated in 77 (36%) of the patients in the whole group and 7 (46.7%) of 15 patients with troponin positivity. C-reactive protein levels were similar between groups. CONCLUSION: Routine troponin screening does not yield much information in previously healthy paediatric COVID-19 patients without any sign of myocardial dysfunction. Elevated troponin levels may be observed but it is mostly a sign of myocardial injury without detectable myocardial dysfunction in this group of patients.

Multisystem Inflammatory Syndrome in Children Admitted to a Tertiary Pediatric Intensive Care Unit.

Background Multisystem inflammatory syndrome in children (MIS-C) is characterized by persistent fever, abdominal pain, vomiting, diarrhea, rash, conjunctivitis, headaches, and mucocutaneous manifestations and it can cause circulatory dysfunction, resulting in hypotension, shock, and end-organ injury in the heart and other organs and possibly death. In this study, we aimed to analyze the clinical spectrum, treatment options and outcomes of children with MIS-C who were admitted to our pediatric intensive care (PICU). Materials and Methods Clinical and laboratory findings and treatment of the patients admitted to the PICU with MIS-C between April 2020 and January 2021 were recorded, and their outcomes were evaluated. Results Nineteen patients with a median age of 12.5 years (interquartile range (IQR): 5.8-14.0 years) were admitted. Eleven (57.8%) were males. The most frequent clinical and laboratory features were fever (100%), abdominal pain (94.7%), rash (63.1%), headache (68.4%), diarrhea (47.3%), seizure (10.5%), cardiac dysfunction (52.6%), acute kidney injury (26.3%), lymphopenia (84.2%), and thrombocytopenia (36.8%). However, 8 patients needed mechanical respiratory support, 11 patients needed inotropes, 2 patients needed plasma exchange, and 1 patient needed continuous renal replacement therapy. All patients received corticosteroids, 17 patients (89.2%) received intravenous immunoglobulin, 2 patients received anakinra, 10 patients received acetylsalicylic acid, and 6 patients received enoxaparin. Median PICU length of stay was 3 days (IQR: 2-5) and only one patient died. Conclusion In conclusion, MIS-C may present with a variety of clinical manifestations, and it can lead to life-threatening critical illness. Most children need intensive care and the response to immunomodulation is usually favorable.

Epidemiological, Clinical, and Laboratory Features of Children With COVID-19 in Turkey.

Objectives: The aim of this study is to identify the epidemiological, clinical, and laboratory features of coronavirus disease 2019 (COVID-19) in children. Methods: A retrospective study was conducted by pediatric infectious disease specialists from 32 different hospitals from all over Turkey by case record forms. Pediatric cases who were diagnosed as COVID-19 between March 16, 2020, and June 15, 2020 were included. Case characteristics including age, sex, dates of disease onset and diagnosis, family, and contact information were recorded. Clinical data, including the duration and severity of symptoms, were also collected. Laboratory parameters like biochemical tests and complete blood count, chest X-ray, and chest computed tomography (CT) were determined. Results: There were 1,156 confirmed pediatric COVID-19 cases. In total, male cases constituted 50.3% (n = 582) and females constituted 49.7% (n = 574). The median age of the confirmed cases was 10.75 years (4.5-14.6). Of the total cases, 90 were younger than 1 year of age (7.8%), 108 were 1-3 years of age (9.3%), 148 were 3-6 years of age (12.8%), 298 were 6-12 years of age (25.8%), 233 were 12-15 years of age (20.2%), and 268 cases were older than 15 years of age (23.2%). The most common symptom of the patients at the first visit was fever (50.4%) (n = 583) for a median of 2 days (IQR: 1-3 days). Fever was median at 38.4°C (38.0-38.7°C). The second most common symptom was cough (n = 543, 46.9%). The other common symptoms were sore throat (n = 143, 12.4%), myalgia (n = 141, 12.2%), dyspnea (n = 118, 10.2%), diarrhea (n = 112, 9.7%), stomachache (n = 71, 6.1%), and nasal discharge (n = 63, 5.4%). When patients were classified according to disease severity, 263 (22.7%) patients were asymptomatic, 668 (57.7%) patients had mild disease, 209 (18.1%) had moderate disease, and 16 (1.5%) cases had severe disease. One hundred and forty-nine (12.9%) cases had underlying diseases among the total cases; 56% of the patients who had severe disease had an underlying condition (p < 0.01). The need for hospitalization did not differ between patients who had an underlying condition and those who do not have (p = 0.38), but the need for intensive care was higher in patients who had an underlying condition (p < 0.01). Forty-seven (31.5%) of the cases having underlying conditions had asthma or lung disease (38 of them had asthma). Conclusions: To the best of our knowledge, this is one of the largest pediatric data about confirmed COVID-19 cases. Children from all ages appear to be susceptible to COVID-19, and there is a significant difference in symptomatology and laboratory findings by means of age distribution.

The incidence and clinical effects of Bordetella pertussis in children hospitalized with acute bronchiolitis.

BACKGROUND: Pertussis is a disease leading to high morbidity and mortality in neonates and infants. Bronchiolitis is the most common cause of hospitalization especially in children < 2 year-old. Although the clinical findings are different in these two diseases, it is sometimes difficult to make this distinction in partially or fully vaccinated children. This study aimed to identify the incidence, clinical and laboratory effects of B. pertussis as a causative agent in hospitalized children with acute bronchiolitis. METHODS: The study included patients diagnosed with acute bronchiolitis and admitted to the Division of Pediatric Infectious Diseases from January 2012 to December 2015, aged 24 months or younger, evaluated for viruses and bacteria with polymerase chain reaction in respiratory tract secretions. RESULTS: The study included 380 patients hospitalized with acute bronchiolitis. Of these patients, 85.8% were identified to be positive for at least one respiratory pathogen. The most commonly identified pathogens were respiratory syncytial virus (RSV) A/B, rhinovirus, parainfluenza virus, adenovirus, bocavirus and metapneumovirus A/B. B. pertussis was only detected in 5 patients (1.5%). In the patients with B. pertussis identified, coinfection with another virus was observed including rhinovirus (n= 2), influenza A virus (n= 1), coronavirus OC43 (n= 1) and RSV A/B (n= 1). The presence of B. pertussis did not appear to cause any significant clinical or laboratory differences in patients. CONCLUSIONS: B. pertussis is a rare pathogen in patients admitted to hospital for acute bronchiolitis. However, in patients who do not respond to standard bronchiolitis treatment, B. pertussis should be considered as a causative agent. Early identification of this pathogen is important in terms of quarantining the patient, administering appropriate antimicrobial treatment, and prophylactic treatment to household and other close contacts.
