Multisystem inflammatory syndrome in children associated with COVID-19 in 101 cases from Turkey (Turk-MISC study).

AIM: Multisystem inflammatory syndrome in children (MIS-C) may cause shock and even death in children. The aim of this study is to describe the clinical features, laboratory characteristics and outcome of children diagnosed with MIS-C in 25 different hospitals in Turkey. METHODS: The retrospective study was conducted between 8 April and 28 October 2020 in 25 different hospitals from 17 cities. Data were collected from patients' medical records using a standardised form. Clinical and laboratory characteristics and outcomes according to different age groups, gender and body mass index percentiles were compared using multivariate logistic regression analysis. RESULTS: The study comprised 101 patients, median age 7 years (interquartile range (IQR) 4.6-9.3); 51 (50.5%) were boys. Reverse-transcriptase polymerase chain reaction (PCR) assay was positive in 21/100 (21%) patients; 62/83 (74.6%) patients had positive serology for SARS-CoV-2. The predominant complaints were fever (100%), fatigue (n = 90, 89.1%), and gastrointestinal symptoms (n = 81, 80.2%). Serum C-reactive protein (in 101 patients, median 165 mg/L; range 112-228), erythrocyte sedimentation rate (73/84, median 53 mm/s; IQR 30-84) and procalcitonin levels (86/89, median 5 µg/L; IQR 0.58-20.2) were elevated. Thirty-eight patients (37.6%) required admission to intensive care. Kawasaki disease (KD) was diagnosed in 70 (69.3%) patients, 40 of whom had classical KD. Most patients were treated with intravenous immunoglobulin (n = 92, 91%) and glucocorticoids (n = 59, 58.4%). Seven patients (6.9%) died. CONCLUSION: The clinical spectrum of MIS-C is broad, but clinicians should consider MIS-C in the differential diagnosis when persistent fever, fatigue and gastrointestinal symptoms are prominent. Most patients diagnosed with MIS-C were previously healthy. Immunomodulatory treatment and supportive intensive care are important in the management of cases with MIS-C. Glucocorticoids and intravenous immunoglobulins are the most common immunomodulatory treatment options for MIS-C. Prompt diagnosis and prompt treatment are essential for optimal management.

Comparison of clinical and laboratory features in coronavirus disease 2019 and pediatric multisystem inflammatory syndrome patients.

BACKGROUND: The coronavirus disease 2019 (COVID-19) and pediatric multisystem inflammatory syndrome (PIMS) are a major public health issue affecting many people worldwide. Although there are new studies in children, little is known about these two new conditions. The aim of this study was to evaluate and compare the clinical and laboratory features of children with COVID-19 and PIMS. METHODS: We conducted a prospective, single-center study of pediatric COVID-19 and PIMS at a tertiary care hospital in Turkey between November 2020 and March 2021. RESULTS: A total of 115 patients with COVID-19 and PIMS were examined during the study period. The median age was 60 (range, 1-215) months and 64% of the patients were male. The most common clinical symptoms were fever (70%) and cough (43%). Conjunctivitis and skin rash were not seen in PIMS patients. Of all patients, 64% had a history of close contact in household. Lymphopenia was present in 34/115 (30%) patients. Acute phase reactants were significantly higher in PIMS patients. Abnormal chest computed tomography scan findings were detected in 68% of the patients, while 36% had abnormal echocardiographic findings. In multivariate analysis, longer duration of fever, diarrhea, lower thrombocyte and higher neutrophil count were significantly associated with diagnosis of PIMS. The treatment included antibiotics, favipiravir, intravenous immunoglobulin, corticosteroids, interleukin-1 blockade. and supportive therapy. Seven patients (6%) required intensive care support. All patients were discharged without any complications, except one who died. CONCLUSIONS: Longer duration of fever, diarrhea, lower thrombocyte, and higher neutrophil count can warn clinicians for diagnosis of PIMS.

Can we predict risk for cardiac involvement in paediatric inflammatory multi-system syndrome?

INTRODUCTION: Increasing recognition of paediatric inflammatory multi-system syndrome is a cause of concern. This study aimed to evaluate children with paediatric inflammatory multi-system syndrome and compare the clinical and laboratory features of children with and without cardiac involvement. MATERIAL AND METHODS: We conducted a prospective single-centre study including 57 (male 37, 65%) patients with paediatric inflammatory multi-system syndrome at a tertiary care hospital between November, 2020 and March, 2021. The mean age was 8.8 ± 4.5 years (range, 10 months-16.7 years). RESULTS: The most frequent symptoms were fever (100%), abdominal pain (65%) and diarrhoea (42%). SARS-CoV-2 PCR and serology tests were positive in 3 (5%) and 52 (91%) patients, respectively. Eight patients required intensive care support. Nineteen patients (33%) had cardiac involvement (valvular regurgitation in 15, left ventricular systolic dysfunction in 11 and coronary artery dilation in 1). The presence and duration of cough and intensive care admissions were significantly higher in children with cardiac involvement than those without it. The cut-off values of troponin T, pro-brain natriuretic peptide and interleukin 6 for predicting cardiac involvement were 11.65 ng/L (95% confidence interval, 0.63-0.90; sensitivity, 0.63; specificity, 0.84; area under the curve: 0.775, p = 0.009), 849.5 pg/mL (95% CI, 0.54-0.86; sensitivity, 0.63; specificity, 0.63; area under the curve: 0.706, p = 0.009) and 39.8 pg/mL (95% CI, 0.54-0.85; sensitivity, 0.63; specificity, 0.60; area under the curve: 0.698, p = 0.023), respectively. CONCLUSIONS: Cardiac involvement in children with paediatric inflammatory multi-system syndrome is common. The risk of cardiac involvement can be predicted by troponin T, pro-brain natriuretic peptide and interleukin 6 levels.

How safe are children with COVID-19 from cardiac risks? Pediatric risk assesment; insights from echocardiography and electrocardiography

Background/aim: Approximately 40 million individuals worldwide have been infected with SARS-CoV-2, the virus responsible for the novel coronavirus disease-2019 (COVID-19). Despite the current literature about the cardiac effects of COVID-19 in children, more information is required. We aimed to determine both cardiovascular and arrhythmia assessment via electrocardiographic and echocardiographic parameters. Materials and methods: We evaluated seventy children who were hospitalized with COVID-19 infections and seventy children as normal control group through laboratory findings, electrocardiography (ECG), and transthoracic echocardiography (TTE). Results: We observed significantly increased levels of Tp-Te, Tp-Te/QT, and Tp-Te/QTc compared with the control group. Twenty-five of 70 (35.7%) patients had fragmented QRS (fQRS) without increased troponin levels. On the other hand, none of the patients had pathologic corrected QT(QTc) prolongation during the illness or its treatment. On TTE, 20 patients had mild mitral insufficiency, among whom only five had systolic dysfunction (ejection fraction < 55%). There was no significant difference between the patient and control groups, except for isovolumic relaxation time (IVRT) in terms of mean systolic and diastolic function parameters. IVRT of COVID patients was significantly lower than that of control group. Conclusion: Despite all the adult studies, the effects of COVID­19 on myocardial function are not well established in children. The thought that children are less affected by the illness may be a misconception.

Ventriculoperitoneal shunt infections and re-infections in children: a multicentre retrospective study.

PURPOSE: Ventriculoperitoneal shunt (VPS) is the most common treatment modality for hydrocephalus. However, VPS infection is a common and serious complication with high rates of mortality and morbidity. The objective of this study was to investigate causative agents and the management of VPS infections and to identify risk factors for re-infection in children. MATERIALS AND METHODS: Retrospective, multicentre study on patients with VPS infection at paediatric and neurosurgery departments in four tertiary medical centres in Turkey between January 2011 and September 2014. RESULTS: A total of 290 patients with VPS infections were identified during the study period. The aetiology of hydrocephalus was congenital malformations in 190 patients (65.5%). The most common symptom of shunt infection was fever in 108 (37.2%) cases. At least one pathogen was identified in 148 VPS infections (51%). The most commonly isolated pathogen was coagulase-negative staphylococci, which grew in 63 cases (42.5%), followed by Pseudomonas aeruginosa in 22 cases (14.9%), Klebsiella pneumoniae in 15 cases (10.1%), and Staphylococcus aureus in 15 cases (10.1). The median duration of VPS infection was 2 months (range, 15 days to 60 months) after insertion of the shunt, with half (49.8%) occurring during the first month. VPS infection was treated by antibiotics and shunt removal in 211 cases (76.4%) and antibiotics alone without shunt removal in 65 patients (23.5%). Among the risk factors, CSF protein level greater than 100 mg/dL prior to VPS insertion was associated with a potential risk of re-infection (OR, 1.65; p =.01). CONCLUSION: High protein levels (>100 mg/dL) before the re-insertion of a VPS may be a risk factor for VPS re-infection.

IL12Rß1 defect presenting with massive intra-abdominal lymphadenopathy due to Mycobacterium intracellulare infection.

Infections due to non-tuberculous mycobacteria species are problematic for immunodeficient individuals. Mendelian susceptibility to mycobacterial diseases (MSMD) defines a group of genetic defects affecting cellular interactions and the interferon (IFN)-γ pathway. Patients with MSMD may present with a disseminated infection resulting from the Bacillus Calmette-Guerin vaccine, Mycobacterium tuberculosis complex, environmental nontuberculous mycobacteria or Salmonella species. Atypical mycobacterial infections and deficient granuloma or giant cell formation are important indicators for MSMD, especially in patients with a family history of parental consanguineous marriage. Herein we report the case of a boy with an IL-12Rß1 defect who presented with massive intraabdominal lymphadenopathy due to Mycobacterium intracellulare infection. The patient was born to consanguineous parents, both heterozygous for the IL-12Rß1 defect mutation. Debulking surgery was planned in order to decrease the abdominal mass, but could not be performed due to a high risk of fatal outcomes. He has been receiving linezolid, levofloxacin, azithromycin, rifabutin and IFN-γ therapy for the past 14 months. At follow-up, the patient showed significant clinical improvement and weight gain.

The Epidemiological Features and Pathogen Spectrum of Respiratory Tract Infections, Istanbul, Türkiye, from 2021 to 2023.

Respiratory tract infections (RTIs) can lead to both recurrent seasonal epidemic outbreaks and devastating pandemics. The aim of this study was to evaluate the epidemiologic characteristics and pathogen spectrum of RTIs using a multiplex RT-PCR panel. A total of 9354 cases with suspected RTIs between February 2021 and July 2023 were included in this study. A total of 11,048 nasopharyngeal and oropharyngeal samples from these patients were analyzed for 23 respiratory tract pathogens using multiplex RT-PCR. H. influenzae and S. pneumoniae were considered as colonizing bacteria. At least one pathogen was detected in 70.66% of the samples; viral pathogens were detected in 48.41% of the samples, bacterial pathogens were detected in 16.06% of the samples, and viral + bacterial pathogens were detected in 35.53% of the samples. The most frequently detected viral pathogen was rhinovirus/enterovirus (RV/EV) (19.99%). Interestingly, in 2021, respiratory syncytial virus A/B showed atypical activity and replaced RV/EV as the most prevalent pathogen. Human bocavirus, H. influenzae, and S. pneumoniae were detected at higher rates in males (p: 0.038, p: 0.042, and p: 0.035, respectively), while SARS-CoV-2 and B. pertussis were detected at higher rates in females (p < 0.001 and p: 0.033). RTIs were found at higher rates in children (p < 0.001). SARS-CoV-2 and human coronaviruses 229E were detected at higher rates in adults (p < 0.001 and p: 0.001). This comprehensive study with a large sample size investigating RTI pathogens was the first in Türkiye. Understanding the current viral circulation using multiplex RT-PCR panels enables clinicians to predict the most likely pathogens affecting patients and contributes to patient management, in addition to anticipating potential threats.

Predictors of pulmonary involvement in children with COVID-19: How strongly associated is viral load?

The purpose of this study was to identify risk factors for pulmonary involvement by examining the demographic, clinical, and laboratory characteristics of children with COVID-19. We performed a retrospective single-center study of COVID-19 in children treated at a tertiary care hospital in Turkey from December 2020 to June 2021. During the course of the study, 126 patients were evaluated, of whom 70/126 were male. The patients' ages ranged from 1 to 216 (mean, 4.73 ± 81.11) months. Fever (65.9%), cough (52.4%), and shortness of breath (18.3%) were the most common symptoms of COVID-19. Ten patients required noninvasive mechanical ventilation. Sixty-nine patients (54.8%) had pneumonia. Longer duration of fever, hospitalization, and the presence of cough were significantly associated with pulmonary involvement. Children with pneumonia had significantly higher levels of C-reactive protein (CRP), procalcitonin, erythrocyte sedimentation rate (ESR), and viral load, and significantly lower counts of lymphocytes and thrombocytes. The cutoff viral load, CRP, and procalcitonin values for predicting pulmonary involvement were 26.5 cycle threshold (Ct; 95% confidence interval [CI], 0.54-0.74; sensitivity, 0.65; specificity, 0.56; area under curve [AUC]: 0.647, p = 0.005), 7.85 mg/L (95% CI, 0.56-0.75; sensitivity, 0.66; specificity, 0.64; AUC = 0.656; p = 0.003) and 0.105 ng/ml (95% CI, 0.52-0.72; sensitivity, 0.55; specificity, 0.58; AUC = 0.626; p = 0.02), respectively. High CRP, procalcitonin levels, ESR, and viral load, and low lymphocyte and thrombocyte counts can predict pulmonary involvement in children with COVID-19, so better management may be provided for good prognosis.

Delayed diagnosis of homocystinuria presenting with coronavirus disease 2019 in a 17-year-old boy.

Homocystinuria is a treatable autosomal recessive inherited disorder. This condition may cause life-threatening complications such as thromboembolic events. Coronavirus disease 2019 (COVID-19) is associated with an increased risk of venous thromboembolic events. Here, we report a case of late diagnosis of homocystinuria presenting with deep venous thrombosis and COVID-19. This study highlights a sustained high index of suspicion for homocystinuria to prevent severe thromboembolic complications.

Diagnostic challenges of old diseases in the COVID-19 era: a report of two cases of carbamazepine-induced DRESS syndrome.

INTRODUCTION: A new MIS-C that develops after the acute stage of COVID-19 infection has recently been reported worldwide. Drug reaction with eosinophilia and systemic symptoms syndrome is a rare but potentially severe adverse drug-induced reaction most commonly associated with anticonvulsants. Due to variability in clinical presentation involving cutaneous and multiorgan systems, broad differential diagnosis, and lack of definitive diagnostic tests, diagnosis may be delayed. CASE REPORTS: The authors report 2 cases of pediatric patients who presented with fever, diffuse rash, and exposure to COVID-19 infection with suspected MIS-C. Both patients' medical histories revealed carbamazepine treatment for approximately 2 months. The diagnosis of DRESS syndrome was associated with the use of carbamazepine. CONCLUSIONS: Distinguishing between MIS-C and DRESS syndrome may be difficult due to similar clinical and laboratory features and the lack of definitive diagnostic tests for either condition. When encountering cases like the current report, it is important to consider DRESS syndrome for early diagnosis and medical intervention.

Successful Treatment of Fasciola hepatica with Metronidazole in a Child: A Case Report.

Fasciola hepatica is a zoonotic liver trematode that usually causes infection in cattle and sheep, and is transmitted to humans by consuming water and aquatic plants contaminated with metacercaria. The detection of Fasciola eggs in stools, serological evaluation and radiological evaluation are essential for diagnosis. Triclabendazole is the first-line therapy for fascioliasis. However, as triclabendazole is not an easily accessible drug in countries such as Turkey, it reveals a quest for alternative therapies. In this report, we present a 10-year-old boy with fascioliasis successfully treated with a course of metronidazole 1.5 g/day for 3 weeks in 2020. During the follow-up, eosinophilia and radiological findings completely recovered. Here we report a case of pediatric fascioliasis that was cured with metronidazole successfully.

COVID-19 disease characteristics in different pediatric age groups.

INTRODUCTION: Little is known about the COVID-19 disease characteristics and differences between different pediatric age groups. This study aimed to investigate the disease characteristics according to age groups. METHODOLOGY: We conducted a retrospective, single-center study of pediatric COVID-19 in a tertiary care hospital in Turkey. The patients were divided into three groups: 15 days-24 months old (Group 1), 25-144 months old (Group 2), and 145-210 months old (Group 3) according to age. RESULTS: A total of 139 pediatric patients with COVID-19 were examined. Twenty-nine patients (20.9%) were in Group 1, 52 (37.4%) were in Group 2, 58 (41.7%) were in Group 3. Thirty-nine patients (28.1%) were hospitalized. The most common symptoms were cough (55.4%) and fever (51.8%). The median chest X-ray (CXR) score of hospitalized patients was 1 (min 0-max 7), and the median CXR score of outpatients was 1 (min 0-max 6). Fever was significantly more frequent in Group 1, and chest pain was more frequent in Group 3. Group 1 had significantly higher WBC, lymphocyte, thrombocyte counts, AST, LDH, D-dimer, and Troponin T levels but lower hemoglobin, total protein, and albumin levels. The treatment included antibiotics, oseltamivir, hydroxychloroquine, and supportive therapy. Only one patient (0.7%) received non-invasive mechanical ventilatory support. CONCLUSIONS: As we know the clinical course of COVID-19 in children is less severe than in adults. We also found significant differences in both clinical and laboratory findings between different pediatric age groups which supports the theory that disease pathogenesis is highly variable according to age.

Evaluation of infants with HIV-infected mothers and perinatal transmission in Turkey: A single-center experience.

OBJECTIVE: The most common route of HIV infection in children is through perinatal transmission. In this study, we aimed to evaluate the characteristics of infants with HIV-infected mothers and perinatal HIV transmission. METHODS: We conducted a retrospective, single-center study of HIV-exposed infants in between December 2017 and October 2019 in a Marmara University Pendik Training and Research Hospital. RESULTS: A total of 18 infants were examined. All babies were born by cesarean section, and none of them were breastfed. Seventeen mothers were diagnosed with HIV before pregnancy. These mothers had received antiretroviral therapy (ART) during pregnancy, and their viral loads before delivery were negative. An antiretroviral prophylaxis with oral zidovudine was started in all infants within their 1st day of birth and continued for at least 6 weeks. All infants were tested for their HIV viral load within the first 48 h of birth, with negative results, and 12 infants were tested for anti-HIV antibodies at the 18th month, again with negative results. In this study, we determined that none of the infants had been infected with HIV. CONCLUSION: Our findings highlight the importance of initiating ART for all HIV-infected pregnant women and the importance of protection modalities during pregnancy, delivery, and the postnatal period for the prevention of perinatal transmission of HIV.

Cost and length of hospital stay for healthcare facilityonset Clostridioides Difficile infection in pediatric wards: a prospective cohort analysis.

BACKGROUND: Clostridioides difficile (C. difficile) is a well-known causative agent of healthcare associated infection, it increases medical cost besides increasing morbidity and mortality. This study was conducted to determine the incidence, and economic burden of healthcare facility-onset C. difficile infection (HO-CDI) in children. METHODS: Data was acquired with a prospective cohort study conducted in pediatric wards of a tertiary university hospital between August 2015 to August 2016. The HO-CDI was defined as diarrhea that began after 48 hours of admission with a positive cytotoxic stool assay for the presence of toxin A and/or B of C. difficile. RESULTS: In the 3172 admissions in one year, 212 (7%) healthcare associated diarrhea (HAD) episodes were observed, in 25 (12%) of them C. difficile was identified in which 6 (25%) cases < 2-year-old. The incidence of HOCDI was estimated as 8.8/10,000 patient-days. Cases with HO-CDI (n=19) were compared with cases with non- CDI-HAD (n=102); the presence of one of the risk factors for CDI increased the risk for HO-CDI (5,05; 95% Cl: 1.10-23.05; P 0,037), the median length of stay (LOS) attributable HO-CDI was 7 days (IQR,5-10) per admission, whereas for non-CDI-HAD was 2 days (IQR,0-4) (p=0.036). General hospitalization costs in the two groups were similar, specifically estimated costs attributable to HO-CDI and non-CID-HAD were $294.0 and $137.0 per hospitalization respectively (p= < 0.0001). CONCLUSION: Although in children the incidence of HO-CDI is increasing, its clinical manifestation is still milder and effective infection control measures with antibiotic stewardship can limit related morbidly, mortality, LOS, and cost.

Reduction of nosocomial infections in the intensive care unit using an electronic hand hygiene compliance monitoring system.

INTRODUCTION: Healthcare-associated infection is an important cause of mortality and morbidity worldwide. Well-regulated infection control and hand hygiene are the most effective methods for preventing healthcare-associated infections. This study evaluated and compared conventional hand hygiene observation and an electronic hand-hygiene recording and reminder system for preventing healthcare-associated infections. METHODOLOGY: This pre- and post-intervention study, employed an electronic hand-hygiene recording and reminder system for preventing healthcare-associated infections at a tertiary referral center. Healthcare-associated infection surveillance was recorded in an anesthesia and reanimation intensive care unit from April 2016 to August 2016. Hand-hygiene compliance was observed by conventional observation and an electronic recording and reminder system in two consecutive 2-month periods. healthcare-associated infections were calculated as incidence rate ratios. RESULTS: The rate of healthcare-associated infections in the electronic hand- hygiene recording and reminder system period was significantly decreased compared with that in the conventional hand-hygiene observation period (incidence rate ratio = 0.58; 95% confident interval = 0.33-0.98). Additionally, the rate of central line-associated bloodstream infections and the rate of ventilator-associated pneumonia were lower during the electronic hand hygiene recording and reminder system period (incidence rate ratio= 0.41; 95% confident interval = 0.11-1.30 and incidence rate ratio = 0.67; 95% confident interval = 0.30-1.45, respectively). CONCLUSIONS: After implementing the electronic hand hygiene recording and reminder system, we observed a significant decrease in healthcare-associated infections and invasive device-associated infections. These results were encouraging and suggested that electronic hand hygiene reminder and recording systems may reduce some types of healthcare-associated infections in healthcare settings.

Multicenter prospective surveillance study of viral agents causing meningoencephalitis.

The frequency of bacterial factors causing central nervous system infections has decreased as a result of the development of our national immunization program. In this study, it is aimed to obtain the data of our local surveillance by defining the viral etiology in cases diagnosed with meningoencephalitis for 1 year. Previously healhty 186 children, who applied with findings suggesting viral meningoencephalitis to 8 different tertiary health centers between August 2018 and August 2019, in Istanbul, were included. The cerebrospinal fluid (CSF) sample was evaluated by polymerase chain reaction. The M:F ratio was 1.24 in the patient group, whose age ranged from 1 to 216 months (mean 40.2 ± 48.7). Viral factor was detected in 26.8%. Enterovirus was the most common agent (24%) and followed by Adenovirus (22%) and HHV type 6 (22%). In the rest of the samples revealed HHV type 7 (10%), EBV (6%), CMV (6%), HSV type 1 (6%), Parvovirus (4%) and VZV (2%). The most common symptoms were fever (79%) and convulsions (45.7%). Antibiotherapy and antiviral therapy was started 48.6% and 4% respectively. Mortality and sequela rate resulted 0.53% and 3.7%, respectively. This highlights the importance of monitoring trends in encephalitis in Turkey with aview to improving pathogen diagnosis for encephalitis and rapidly identifying novel emerging encephalitis-causing pathogens that demand public health action especially in national immunisation programme.

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.

Knowledge and acceptance of influenza and pertussis vaccinations among pregnant women of low socioeconomic status in Turkey.

Pregnant women and infants are at relatively high risk for influenza- and pertussis-related morbidity and mortality. Vaccination is the most important prevention strategy for both diseases. We evaluated knowledge and acceptance of influenza and pertussis vaccinations among pregnant women. We performed a cross-sectional survey of 465 pregnant women receiving prenatal care at the obstetric outpatient clinic in a tertiary medical center in Turkey between November 2015 and May 2016. We used a questionnaire investigating the knowledge of pertussis and influenza to evaluate potential influences on the acceptance or rejection of pertussis or influenza vaccinations. The acceptance rates of pertussis and influenza vaccinations were 11.2% and 19.8%, respectively. Maternal age, education level, employment status, number of gestations, and gestational age did not affect the rate of acceptance of these vaccinations. On the other hand, pregnant women who had a history of vaccination during their adolescence and in previous pregnancies were significantly more likely to accept pertussis vaccination. Knowledge about the risks of pertussis and influenza diseases for pregnant women and their children has a significant effect on vaccination acceptance. Even in low socioeconomic status groups, a recommendation for vaccinations by the primary obstetrician was significantly predictive of acceptance of both pertussis and influenza vaccination. This study revealed that the acceptance rates of pertussis and influenza vaccination among pregnant women are very low in Turkey. Healthcare worker recommendations and increased awareness about pertussis and influenza morbidity and mortality in pregnant women and infants are essential to improve the rates of vaccination acceptance during pregnancy.

Successful treatment of allergic bronchopulmonary aspergillosis with posaconazole in a child with cystic fibrosis: Case report and review of the literature.

Allergic bronchopulmonary aspergillosis (ABPA) is recognized as a rare, progressive, allergic disorder in patients with cystic fibrosis (CF) and asthma. Treatment of ABPA mainly includes systemic corticosteroids (CSs) and antifungal agents. Here, we report posaconazole treatment in a 9-year-old male child with ABPA and also review the literature on antifungal management of ABPA. The child with CF was admitted to the emergency room with complaints of fever, productive cough, and acute dyspnea. Auscultation of the lungs revealed obvious bilateral fine crackles and bilateral rhonchus. He was started with intravenous meropenem and amikacin for acute exacerbation. The patient was diagnosed with ABPA because of his failure to respond to antibiotherapy, elevated serum immunoglobulin (Ig) E, specific IgE, to Aspergillus fumigatus levels and sputum growth of A. fumigatus. He was successfully treated with posaconazole with marked clinical and laboratory improvement and no adverse effects. CSs and antifungal agents are the mainstay of therapy in patients with ABPA based on observational studies in children. Posaconazole is a useful treatment option for patients with ABPA.
