Clinical Reflections of Acinetobacter Infections in Children in a Quaternary-Care Hospital: A Five-Year Single-Center Experience.

OBJECTIVE: This study aimed to determine the epidemiology of Acinetobacter species in the last 5 years, the clinical diseases caused by the pathogen, the possible risk factors for infection, and the resistance pattern of the microorganism in our quaternary-care hospital. MATERIALS AND METHODS: In this retrospective cohort study, 67 pediatric cases infected with Acinetobacter species in our hospital between January 2017 and December 2021 were analyzed. Demographic characteristics and clinical and laboratory findings were analyzed. RESULTS: In pediatric patients infected with Acinetobacter spp., the median age was 36 (7-114) months, and 64.2% (n = 43) were female. Acinetobacter baumannii was grown in the cultures of 31 (46.3%) cases. When the type of infection was examined, 31 (46.3%) cases were urinary tract infections, and 29 (43.3%) cases were bloodstream infections. Extensively drug-resistant, pandrug-resistant, and multidrug-resistant A. baumannii were found in 10 (14.9%), 3 (4.5%), and 2 (3%) cases, respectively. Health-care-associated infections were found to have a significant rate of Acinetobacter resistance (P = .002). Significant antimicrobial resistance was detected in Acinetobacter-infected cases with intensive care hospitalization within the last month and carbapenem use in the previous 3 months (P < .001, both). CONCLUSION: It is necessary to act in accordance with the infection prevention and control program to reduce the incidence of health-care-associated infections with Acinetobacter species and to prevent infection with highly resistant strains. Due to health-care-associated infections and factors contributing to the increase in Acinetobacter resistance, we believe this study will help clinicians to be more cautious in the use of carbapenems.

Evaluation of 601 children with multisystem inflammatory syndrome (Turk MISC study).

PURPOSE: Due to its link with the 2019 coronavirus, the multisystem inflammatory syndrome in children (MISC) has garnered considerable international interest. The aim of this study, in which MISC patients were evaluated multicenter, and the data of the third period of the Turk-MISC study group, to compare the clinical and laboratory characteristics and outcomes of MISC patients who did and did not require admission to an intensive care unit (ICU). METHODS: This retrospective multicenter observational study was carried out between June 11, 2021, and January 01, 2022. The demographics, complaints, laboratory results, system involvements, and outcomes of the patients were documented. RESULTS: A total of 601 patients were enrolled; 157 patients (26.1%) required hospitalization in the intensive care unit (ICU). Median age was 8 years (interquartile range (IQR) 4.5-11.3 years. The proportion of Kawasaki disease-like features in the ICU group was significantly higher than in the non-ICU group (56.1% vs. 43.2% p = 0.006). The ICU group had considerably lower counts of both lymphocytes and platelets (lymphocyte count 900 vs. 1280 cells × µL, platelet count 153 vs. 212 cells × 103/ µL, all for p< 0.001). C-reactive protein, procalcitonin, and ferritin levels were significantly higher in the ICU group (CRP 164 vs. 129 mg/L, procalcitonin 9.2 vs. 2.2 µg/L, ferritin 644 vs. 334 µg/L, all for p< 0.001). Being between ages 5-12 and older than 12 increased the likelihood of hospitalization in the ICU by four [95% confidence intervals (CI)1.971-8.627] and six times (95% CI 2.575-14.654), respectively, compared to being between the ages 0-5. A one-unit increase in log D-dimer (µg/L) and log troponin (ng/L) was also demonstrated to increase the need for intensive care by 1.8 (95% CI 1.079-3.233) and 1.4 times (95% CI 1.133-1.789), respectively.     Conclusion: By comparing this study to our other studies, we found that the median age of MISC patients has been rising. Patients requiring an ICU stay had considerably higher levels of procalcitonin, CRP, and ferritin but significantly lower levels of lymphocyte and thrombocyte. In particular, high levels of procalcitonin in the serum might serve as a valuable laboratory marker for anticipating the need for intensive care. WHAT IS KNOWN: • Lymphopenia and thrombocytopenia were an independent predictor factors in patients with MISC who needed to stay in intensive care unit. • The possibility of the need to stay in the intensive care unit in patients with MISC who had Kawasaki disease-like findings was controversial compared with those who did not. WHAT IS NEW: • A one-unit increase log D dimer and log troponin was demonstrated to require for intensive care unit by 1.8 and 1.4 times, respectively. • Serum procalcitonin levels had the best performance to predict stay in the intensive care unit stay.

Evaluation of ischemia-modified albumin in the diagnosis and the clinical severity of COVID-19 in children.

BACKGROUND: There is no specific biomarker used in the diagnosis of COVID-19 and predicting its clinical severity. This study aimed to investigate the utility of ischemia-modified albumin (IMA) in diagnosing and predicting clinical severity in children with COVID-19. METHODS: Between October 2020 and March 2021, 41 cases constituted the COVID-19 group and 41 cases constituted the healthy control group. IMA levels were measured at admission (IMA-1) and 48-72 hours (IMA- 2) in the COVID-19 group. In the control group, it was measured at admission. COVID-19 clinical severity was classified as asymptomatic infection, mild, moderate, severe, or critical disease. Patients were divided into two groups (asymptomatic/mild and moderate/severe) to evaluate IMA levels in terms of clinical severity. RESULTS: In the COVID-19 group, the mean IMA-1 level was 0.901±0.099, and the mean IMA-2 level was 0.866±0.090. The mean level of IMA-1 in the control group was 0.787±0.051. When IMA-1 levels of COVID-19 and control cases were compared, the difference was statistically significant (p < 0.001). When clinical severity and laboratory data are compared, C-reactive protein, ferritin and ischemia-modified albumin ratio (IMAR) were statistically significantly higher in moderate-severe clinical cases (p=0.034, p=0.034, p=0.037 respectively). However, IMA-1 and IMA-2 levels were similar between the groups (p=0.134, p=0.922, respectively). CONCLUSIONS: To date, no study has been conducted on IMA levels in children with COVID-19. The IMA level may be a new marker for the diagnosis of COVID-19 in children. Studies with a larger number of cases are needed to predict clinical severity.

Parental Attitudes About Lumbar Puncture in Children With Suspected Central Nervous System Infection.

OBJECTIVES: This study aimed to evaluate parents' attitudes toward lumbar puncture (LP) for their children with suspected central nervous system infection to determine the reasons for rejection and related factors. METHODS: The survey was provided to parents of children (1 month to 18 years old) for whom LP was recommended because of a concern for central nervous system infection. Sociodemographic characteristics and other related factors of parents who did and did not approve of LP were compared statistically. The reasons for the disapproval of parents who refused LP were revealed. RESULTS: A total of 100 parents were included in the study. Eighty-two percent of the participating parents were mothers, and the median age of the mothers was 31 years (min: 17 years; max: 70 years). The median age of the fathers was 37 years (min: 22 years; max: 60 years). Among the parents, 34% did not give consent for LP. The most common reason for the participants to refuse LP was fear of paralysis of their children due to the procedure (82.3%). There was a statistical difference between the approval of the LP procedure and the person who informed the parents about the LP procedure and read the informed consent form ( P = 0.004 and P = 0.038, respectively).As a result of the binary logistic regression analysis, it was seen that the rate of acceptance of the LP procedure by the parents informed by the specialist doctors was 7.1-fold ( P = 0.02; 95% confidence interval, 1.3-37.6) higher than the parents informed by the resident physicians. CONCLUSION: The informed consent process mainly influenced parents' attitudes toward LP. To increase the acceptance rates of LP, we should standardize the informed consent process so that it is not affected by factors such as seniority of the physician.

Association between mannose binding lectin gene polymorphisms and clinical severity of COVID-19 in children.

BACKGROUND: Mannose-binding lectin (MBL) is a member of innate immunity and acts with MASP (MBL-associated serine protease) to activate the lectin pathway of the complement system. MBL gene polymorphisms are associated with susceptibility to infectious diseases. This study investigated whether MBL2 genotype, serum MBL levels, and serum MASP-2 levels affect the course of SARS-CoV-2 infection. METHODS AND RESULTS: Pediatric patients diagnosed with COVID-19 by positive real-time polymerase chain reaction (PCR) were included in the study. Single nucleotide polymorphisms in the promoter and exon 1 in the MBL2 gene (rs11003125, rs7096206, rs1800450, rs1800451, rs5030737) were identified by a PCR and restriction fragment length polymorphisms analysis. Serum MBL and MASP-2 levels were measured by ELISA. COVID-19 patients were divided into asymptomatic and symptomatic. Variables were compared between these two groups. A total of 100 children were included in the study. The mean age of the patients was 130 ± 67.2 months. Of the patients, 68 (68%) were symptomatic, and 32 (32%) were asymptomatic. The polymorphisms in the - 221nt and - 550nt promoter regions did not differ between groups (p > 0.05). All codon 52 and codon 57 genotypes were determined as wild-type AA. AB genotypes were found 45.6% in symptomatic patients while 23.5% in asymptomatics. Moreover, BB genotype was detected 9.4% in symptomatic and 6.3% in asymptomatic patients (p < 0.001). B allele was more frequent in symptomatic patients (46.3%) compared to asymptomatic patients (10.9%). (p < 0.001). Serum MBL and MASP-2 levels did not differ statistically between the groups (p = 0.295, p = 0.073). CONCLUSION: These findings suggest that codon 54 polymorphism in the MBL2 gene exon-1 region can be associated with the symptomatic course of COVID-19.

Attitudes of parents with children aged 12-18 to COVID-19 vaccines for themselves and their children.

BACKGROUND: The incidence of vaccine hesitancy is increasing in many countries. This study aims to determine parents` attitudes and related factors regarding COVID-19 vaccine acceptance for themselves and their children aged 12-18. METHODS: A cross-sectional survey was conducted on parents between 16th November and 31st December 2021, after COVID-19 vaccines were initiated for children in Türkiye. In the survey, the sociodemographic characteristics of the parents, whether they and their children were vaccinated against COVID-19, and if not, the reasons for this were asked. Multivariate binary logistic regression analysis was used to evaluate the factors affecting parents` refusal to vaccinate their children for COVID-19. RESULTS: Three hundred and ninety-six mothers and fathers were included in the final analysis. Overall, 41.7% of parents reported vaccine refusal for their children. COVID-19 vaccine refusal was higher in mothers younger than 35 (ß = 6.5, p = 0.002, 95% CI: 2.0-23.1), children aged 15 and younger (ß = 2.3, p = 0.001, 95% CI: 1.4-3.7). Concerns about the side effects of the COVID-19 vaccine (29.7%) and their children not wanting to be vaccinated (29.0%) were the most common causes of COVID-19 vaccine refusal. CONCLUSIONS: In the present study, the rate of children not vaccinated due to COVID-19 vaccine refusal was relatively high. Parents` concerns about vaccine side effects, as well as their children`s unwillingness to be vaccinated, suggest that both parents and adolescents should be informed about the importance of COVID-19 vaccines.

A prospective long-term evaluation of the ocular findings of children followed with the diagnosis of multisystem inflammatory syndrome (long-term evaluation of ocular findings following MIS-C).

BACKGROUND/OBJECTIVES: The most frequently reported ocular finding in the acute phase of the multisystem inflammatory syndrome in children (MIS-C), is conjunctivitis. More rarely, punctuate epitheliopathy, anterior uveitis and optic disc oedema can be seen. We aimed to investigate the acute and long-term ocular effects of MIS-C. SUBJECTS/METHODS: Cases aged 1 month to 18 years who were diagnosed with MIS-C between January 2022 and June 2022 in the Department of Pediatric Infectious Diseases in our hospital were included in the study. Ophthalmological examinations were performed immediately after diagnosis, at one month, three months, and six months. RESULTS: Males consisted of 64.7% of the 34 cases included in the study and the mean age was 8.68 ± 4.32 years (min-max:2-17). In the first examination, conjunctivitis was observed in 6 (17.6%), punctuate epitheliopathy in 4 (11.7%), and subconjunctival haemorrhage in 3 (8.8%) patients. Two patients (5.8%) had optic disc oedema. No pathological anterior or posterior segment findings were observed in the sixth-month examination. The relationship between subconjunctival haemorrhage and intensive care hospitalisation was statistically significant (p = 0.014). Also, all patients with subconjunctival haemorrhage were clinically classified as severe MIS-C (p = 0.002). CONCLUSION: Although pathological ocular findings were observed in the acute phase of the disease, all of them were found to be improved at the sixth-month follow-up. The most striking finding of our study is that cases with subconjunctival haemorrhage were clinically more severe, and all patients needed intensive care. This study may be informative in establishing ocular follow-up protocols that are expected to be carried out in the acute period and in the follow-up of these patients.

The diversity in the clinical features of children hospitalized with COVID-19 during the nonvariant, Alpha (B.1.1.7), Delta (B.1.617.2), and Omicron (B.1.1.529) variant periods of SARS CoV-2: Caution for neurological symptoms in Omicron variant.

Since the COVID-19 pandemic began, various severe acute respiratory syndrome coronavirus 2 variants have been identified with different characteristics than the nonvariant strain. We retrospectively evaluated the demographic and clinical differences in the cohort of hospitalized COVID-19 children (1 month-18 years old) between March 11, 2020, and September 31, 2022, by the time the variants identified in our country predominate. Bonferroni post hoc analysis was performed to compare the differences between the periods. Of the 283 children in this study, 142 (50.2%) were females. The median age was 36 (interquartile range [IQR]: 7-132) months. Sixty-three (22.2%) patients were hospitalized in the nonvariant period, 24 (8.5%) in the Alpha period, 93 (32.9%) in the Delta period, and 103 (36.4%) in the Omicron period. Fever was the most common symptom in all groups, with no statistically significant differences (p = 0.25). In the Omicron period, respiratory and gastrointestinal symptoms decreased, and neurological symptoms increased significantly compared to other periods: [respiratory symptoms; nonvariant (65.1%) vs. Omicron (41.7%), (p = 0.024)], [gastrointestinal symptoms; Delta (41.9%) vs. Omicron (22.3%), (p = 0.018), [neurological symptoms; Delta (14.5%) vs. Omicron (31.1%), (p = 0.03]. Altered mental status and seizures were more common during the Omicron period compared to the pre-Omicron (nonvariant, Alpha, and Delta) period (p = 0.017 and p = 0.005, respectively). Although the main symptoms in children with COVID-19 were fever and respiratory symptoms, an increase in severe neurological manifestations was seen throughout the Omicron variant period.

Serum Amyloid A Levels and Severity of COVID-19 in Children.

OBJECTIVE: The aim of this study was to determine the availability of serum amyloid A (SAA) in the diagnosis of coronavirus disease 2019 (COVID-19), to asses disease severity and to predict hospitalization status. METHODS: Between March, 2020 and March, 2021, a total of 80 children (40 cases with COVID-19 and 40 cases in healthy group) were included in this study. Patients were divided into two groups (mild and moderate/severe) to evaluate SAA levels in terms of clinical severity and also hospitalization status. RESULTS: Comparisons between the two groups revealed that median SAA values were significantly higher in children with COVID-19 than in their healthy peers (21.45vs3.05 mg/L, P=0.002). There was no significant difference in the median serum SAA levels between mild and moderate/severe clinical disease (P=0.837). The SAA difference between the two groups with regards to hospitalization was not statistically significant (P=0.098). CONCLUSIONS: Although SAA level was found to be higher in children with COVID 19 compared to healthy controls, the sensitivity of SAA for the disease was found to be low. In addition, there was no difference between the groups in terms of clinical severity.

Differentiating abdominal pain due to COVID-19 associated multisystem inflammatory syndrome from children with acute appendicitis: a score system.

PURPOSE: Differentiating abdominal pain due to coronavirus disease (COVID-19)-associated multisystem inflammatory syndrome (MIS-C) in children with acute appendicitis (AA) can cause diagnostic dilemmas. This study aimed to evaluate the efficacy of a previously described scoring system and improve its diagnostic ability in differentiating between these diseases. METHODS: This study was conducted between March 2020 and January 2022. Patients who had MIS-C with gastrointestinal system (GIS) involvement and patients who underwent surgery for appendicitis were included. First, all patients were evaluated using the new scoring system (NSS). The groups were compared by adding new MISC-specific parameters to NSS. The scoring system was evaluated using propensity score matching (PSM). RESULTS: A total of 35 patients with abdominal pain due to GIS involvement in MIS-C (group A) and 37 patients with AA who had ALT, PRC, and D-dimer results at their first admission (group B) were included in the study. The mean age of patients in group A was lower than that of patients in group B (p < 0.001). False NSS positivity was found in 45.7% of the patients with MIS-C. Lymphocyte (p = 0.021) and platelet counts (p = 0.036) were significantly lower in the blood count and serum D-dimer (p = 0.034), C-reactive protein (CRP) (p < 0.001), and procalcitonin (p < 0.001) were significantly higher in the MIS-C group. We created a scoring system called the Appendicitis-MISC Score (AMS) using the NSS and new parameters. The sensitivity and specificity of AMS diagnostic scores were 91.9% and 80%, respectively. CONCLUSION: MIS-C with GIS involvement may present as acute abdomen. It is difficult to differentiate this condition from acute appendicitis. AMS has been shown to be useful for this differentiation.

Evaluation of possible COVID-19 reinfection in children: A multicenter clinical study.

BACKGROUND: Although it was originally unknown whether there would be cases of reinfection of coronavirus disease 2019 (COVID-19) as seen with other coronaviruses, cases of reinfection were reported from various regions recently. However, there is little information about reinfection in children. METHODS: In this study, we aimed to investigate the incidence and clinical findings of reinfection in pediatric patients who had recovered from COVID-19. We retrospectively evaluated all patients under 18 years of age with COVID-19 infection from a total of eight healthcare facilities in Turkey, between March 2020 and July 2021. Possible reinfection was defined as a record of confirmed COVID-19 infection based on positive reverse transcription-polymerase chain reaction (RT-PCR) test results at least 3 months apart. RESULTS: A possible reinfection was detected in 11 out of 8840 children, which yielded an incidence of 0.12%. The median duration between two episodes of COVID-19 was 196 (92-483) days. When initial and second episodes were compared, the rates of symptomatic and asymptomatic disease were similar for both, as was the severity of the disease (p = 1.000). Also, there was no significant difference in duration of symptoms (p = 0.498) or in hospitalization rates (p = 1.000). Only one patient died 15 days after PCR positivity, which resulted in a 9.1% mortality rate for cases of reinfection in pediatric patients. CONCLUSION: We observed that children with COVID-19 were less likely to be exposed to reinfection when compared with adults. Although the clinical spectrum of reinfection was mostly similar to the first episode, we reported death of a healthy child during the reinfection.

Does the Thymus Index Predict COVID-19 Severity?

BACKGROUND: The COVID-19 (coronavirus disease 2019) pandemic is a global health emergency that is straining health care resources. Identifying patients likely to experience severe illness would allow more targeted use of resources. This study aimed to investigate the association between the thymus index (TI) on thorax computed tomography (CT) and prognosis in patients with COVID-19. METHODS: A multicenter, cross-sectional, retrospective study was conducted between March 17 and June 30, 2020, in patients with confirmed COVID-19. The patients' clinical history and laboratory data were collected after receiving a signed consent form. Four experienced radiologists who were blinded to each other and patient data performed image evaluation. The appearance of the thymus was assessed in each patient using 2 published systems, including the TI and thymic morphology. Exclusion criteria were lack of initial diagnostic thoracic CT, previous sternotomy, pregnancy, and inappropriate images for thymic evaluation. A total of 2588 patients with confirmed COVID-19 and 1231 of these with appropriate thoracic CT imaging were included. Multivariable analysis was performed to predict the risk of severe disease and mortality. RESULTS: The median age was 45 (interquartile range, 33-58) years; 52.2% were male. Two hundred forty-nine (20.2%) patients had severe disease, and 60 (4.9%) patients died. Thymus index was significantly associated with mortality and severe disease (odds ratios, 0.289 [95% confidence interval, 0.141-0.588; P = 0.001]; and 0.266 [95% confidence interval, 0.075-0.932; P = 0.038]), respectively. Perithymic lymphadenopathy on CT imaging had a significantly strong association with grades of TI in patients with severe disease and death ( V = 0.413 P = 0.017; and V = 0.261 P = 0.002, respectively). A morphologically assessable thymus increased the probability of survival by 17-fold and the absence of severe disease by 12-fold. CONCLUSION: Assessment of the thymus in patients with COVID-19 may provide useful prognostic data for both disease severity and mortality.

Can Serum 25-Hydroxy Vitamin D Levels Predict the Severity of Multisystem Inflammatory Syndrome in Children and COVID-19?

Objective: To determine the clinical significance of serum 25-hydroxy (OH) vitamin D levels in pediatric patients with multisystem inflammatory syndrome in children (MIS-C) and compare the vitamin D levels of these patients with those patients with Coronavirus disease-2019 (COVID-19) and healthy controls. Methods: This study was designed for pediatric patients aged 1 month to 18 years and conducted between July 14 and December 25, 2021. Fifty-one patients with MIS-C, 57 who were hospitalized with COVID-19, and 60 controls were enrolled in the study. Vitamin D insufficiency was defined as a serum 25 (OH) vitamin D level of less than 20 ng/mL. Severe MIS-C was classified as necessitating intensive care due to cardiovascular instability, the necessity for non-invasive or invasive mechanical ventilation, and/or a diminishing Glasgow coma scale. World Health Organization definition criteria were used to describe the clinical stages of COVID-19 in children and patients were divided into four groups according to the clinical severity of COVID-19: asymptomatic, mild, moderate, and severe/critical. Results: The median serum 25 (OH) vitamin D was 14.6 ng/mL in patients with MIS-C, 16 ng/mL in patients with COVID-19, and 21.1 ng/mL in the control group (p<0.001). Vitamin D insufficiency was present in 74.5% (n=38) of patients with MIS-C, 66.7% (n=38) of patients with COVID-19, and 41.7% (n=25) of the controls (p=0.001). The percentage of four or more affected organ systems was 39.2% in patients with MIS-C. The correlation between the number of affected organ systems and serum 25 (OH) vitamin D levels was evaluated in patients with MIS-C and there was a moderate negative correlation (r=-0.310; p=0.027). A weak negative correlation was found between the severity of COVID-19 and serum 25 (OH) vitamin D (r=-0.320, p=0.015). Conclusion: Vitamin D levels were insufficient in both the MIS-C and COVID groups. Furthermore, vitamin D levels correlated with the number of affected organ systems in MIS-C and the severity of COVID-19.

Colistin Treatment for Multidrug-Resistant Gram-Negative Infections in Children: Caution Required for Nephrotoxicity.

Objectives: Colistin has come to the fore as a treatment option, especially with the occurrence of multidrug-resistant Gram-negative infections across the world. However, the high nephrotoxic effects of colistin should be taken into consideration in children. The study's primary outcome was to determine the clinical success of the colistin treatment, and the secondary outcome was to detect the side effects related to colistin. Methods: The patients who received intravenous colistin in our hospital's last 5 years were included in the study. In addition to the patients' demographic and clinical characteristics, the clinical success of the colistin treatment, 28-day infection-related mortality of the patients, and side effects of colistin were recorded. Results: A total of 37 patients received colistin therapy during 2015-2019. Four of these patients had colistin treatment twice a year, so we accepted them as separate cases in each infection attack. Therefore, 41 cases were included in the study. The median age of the cases was 26 months (IQR: 4.50-144.50) and 27 (65.9%) were male. Twenty-seven cases (65.9%) had sepsis. The median dose of colistin was 4.2 (IQR: 3-5) mg/kg/day. Among 44 cultures obtained from the patients, the most common microorganism was Acinetobacter baumannii, with 58.5%. The clinical success was detected in 18 patients (43.9%). While overall nephrotoxicity developed in 14 (34.1%) patients, only two of them needed dialysis. Conclusion: Colistin should not be considered the first choice in treating Gram-negative infections but should be kept as salvage therapy in multidrug-resistant Gram-negative infections across the world. During the treatment process, close monitoring of renal function tests and urinary output were recommended due to the risk of developing nephrotoxicity.

Hydatid Disease in Children from Diagnosis to Treatment: A 10-year Single Center Experience

Objective: Hydatid disease caused by Echinococcus granulosus is a parasitic zoonosis and is endemic in Turkey. Clinical manifestations vary and are related to the anatomical location. In this report, we shared the diagnosis, treatment and follow-up of hydatid disease in children with a 10-year experience. Methods: A total of fifty-seven children diagnosed with hydatid disease were analyzed retrospectively from hospital records. Diagnosis was based on clinical, serological and radiological findings. Treatment response was evaluated with clinical, radiological and serological findings. Results: The male/female ratio of 57 cases was 2.4:1 and the mean age was 113.6±45.9 months. The most common presenting complaint was abdominal pain (42.1%). While 22 (38.6%) of the cases had eosinophilia; indirect hemagglutination test positivity was detected in 27 cases (47.4%). Multiple organ involvement was present in 18 cases (31.6%). In patients with multiple organ involvement, the possibility of cysts being located in the abdomen was higher (p=0.005). Of the 50 cases (87.7%), 45 (78.9%) were operated with open surgery and 5 (8.8%) with percutaneous aspiration-injection-reaspiration method for treatment. There were 52 (91.2%) patients who were given albendazole in conservative treatment and the mean duration of treatment was 15.5±17.2 months. There were 10 cases (17.5%) who developed cyst rupture and the symptom duration was shorter than the cases without cyst rupture (p=0.017). Cyst rupture was more common in cases with dyspnea and fluid discharge from the mouth called rock water (p=0.001, p=0.005, respectively). Recurrence was observed in five cases (8.8%) during follow-up. Conclusion: In areas where the disease is endemic, despite prevention and control programs consisting of personal habits and health education, active transmission of hydatid disease is seen in children and continues to be an important public health problem. Hydatid disease should definitely be considered in the presence of suspicious radiological and clinical findings in endemic areas. Controlled clinical studies are required for diagnosis and treatment procedures.

Seasonal coronaviruses infections in children: do they always cause mild illness?

BACKGROUND: Human coronaviruses (HCoVs) cause a comprehensive clinic ranging from asymptomatic course to pneumonia. We aimed to describe the HCoV infections in children to determine the clinical status and coinfection effects in a five-year retrospective surveillance study. The primary outcome was admission to the intensive care unit (ICU) and the secondary outcome was the need of high oxygen support. METHODS: Between September 2015 and November 2020, all patients whose reverse transcription polymerase chain reaction (RT-PCR) tests were positive were determined and patients with HCoVs were included in the study. Demographical characteristics, underlying chronic diseases, clinical diagnosis, laboratory data, subtypes of HCoVs, radiological findings, treatments, hospitalization, and ICU admission were analyzed. RESULTS: Of the 2606 children, the overall respiratory tract virus detection rate was 82.4%. Among these, 98 cases were HCoVs positive and of these 80 (81.6%) were under five years of age and most of the patients were admitted to the hospital in spring and 70% were a mixed infection with other respiratory viruses. Since lower respiratory tract infections are more common in HCoV coinfections, a significant difference was found in clinical diagnosis (p < 0.001). The presence of hypoxia (p=0.003) and underlying disease (p=0.004) were found to be significantly more common in patients admitted to the ICU. The presence of hypoxia, infiltration on chest X-ray, and elevated C-reactive protein levels were more frequently determined in patients who received high oxygen support (p=0.001, p=0.036, p=0.004, respectively). CONCLUSIONS: Clinical findings may be more severe if HCoVs, which generally cause mild respiratory disease, are coinfected with another viral agent.

Evaluation of Depression, Anxiety, and Sleep Quality in Children Diagnosed With COVID-19.

ABSTRACT: COVID-19 has affected individuals of all age groups, both physically and mentally. We aimed to determine anxiety and depression in children diagnosed with COVID-19. Fifty children aged 8 to 18 years diagnosed with COVID-19 were included in the study. The children were evaluated the revised Child Anxiety and Depression Scale, STAI form TX-I (state anxiety inventory), and STAI form TX-II (trait anxiety inventory). Child Sleep Habits Questionnaire was applied for one of the parents according to three different periods. The periods were established as before the pandemic, during the illness-quarantine process, and after the quarantine. We observed the highest scores for depression-anxiety and the poorest sleep quality during the quarantine period. The scores for depression-anxiety were lower, and sleep quality scores were higher in the prepandemic period compared with after the quarantine period. Measures should be taken to protect mental health for children with COVID-19.
