RESUMO
BACKGROUND: Mean platelet volume (MPV), which is regarded as a marker of thrombocyte function and activation, is related to increased morbidity and mortality. In critically ill patients, the ratio of MPV to platelets can independently predict adverse outcomes. This study aimed to investigate the prognostic value of the mean platelet volume/platelet count ratio (MPR) for mortality in children with acute kidney injury (AKI). METHODS: In this retrospective study, patients hospitalized in the pediatric intensive care unit (PICU) between March 2020 and June 2022 were evaluated. Patients between 1 month and 18 years of age with AKI were enrolled. Clinical and laboratory data were compared between survivors and non-survivors. The MPR ratio was calculated on the first and third days of admission to the intensive care unit. A multiple logistic regression analysis was used to determine the association between MPR and mortality. ROC curves were used for the prediction performance of the logistic regression models and cut-off values of the thrombocyte indices. RESULTS: Sixty-three children with AKI were included in the study. The total mortality rate was 34.9% (n=22). MPR ratios were significantly higher in the non-survivors at admission (p=0.042) and at the 72nd hour (p=0.003). In the multiple logistic regression analysis, thrombocyte counts and MPR72h ratio were found to be independent risk parameters for adverse outcomes in children with AKI. CONCLUSIONS: MPR is an inexpensive and practical marker that may predict the outcome of children with AKI.

The aim of this study was to compare scoring systems for mortality prediction and determine the threshold values of these scoring systems in pediatric multitrauma patients. A total of 57 multitrauma patients referred to the pediatric intensive care unit from January 2020 to August 2021 were included. The pediatric trauma score (PTS), injury severity score (ISS), base deficit (B), international normalized ratio (I), Glasgow coma scale (G) (BIG) score, and pediatric risk of mortality 3 (PRISM 3) score were analyzed for all patients. Of the study group, 35% were female and 65% were male with a mean age of 72 months (interquartile range: 140). All groups' mortality ratio was 12.2%. All risk scores based on mortality prediction were statistically significant. Cutoff value for PTS was 3.5 with 96% sensitivity and 62% specificity; for the ISS, it was 20.5 with 92% sensitivity and 43% specificity; threshold of the BIG score was 17.75 with 85.7% sensitivity and 34% specificity; and 12.5 for PRISM 3 score with 87.6% sensitivity and 28% specificity. PTS, ISS, BIG score, and PRISM 3 score were accurate risk predictors for mortality in pediatric multitrauma patients. ISS was superior to PTS, PRISM 3 score, and BIG score for discrimination between survivors and nonsurvivors.

RESUMO
Background/aim: Congenital anomalies of the kidney and urinary tract(CAKUT) are the leading causes of childhood chronic kidney disease (CKD). The etiology of most of the cases is thought to be multifactorial. In this study, risk factors for CAKUT and the effect of mobile phone-related electromagnetic field (EMF) exposure during pregnancy were investigated. Materials and methods: Fifty-seven cases and 57 healthy controls under 2 years of age were included and their mothers were subjected to a questionnaire. Groups were compared for parents' demographics, pregestational (chronic disease, body mass index, use of the folic acid supplements) and antenatal variables (gestational disease, weight gain during pregnancy,) and exposures during pregnancy. To assess mobile phone-related radiation exposure, all participants were asked about their daily call time, the proximity of the phone when not in use, and the models of their mobile phones. The specific absorption rate (SAR) of the mobile phones and the effective SAR value (SAR × call time) as an indicator of EMF exposure were recorded. Results: Excess weight gain according to BMI during pregnancy was related to an increased risk of CAKUT (p=0.012). Folic acid use before pregnancy was protective for CAKUT (p = 0.028). The call time of mothers of the CAKUT group was significantly longer than the control (p = 0.001). An association was observed between higher effective SAR values and increased risk of CAKUT (p = 0.03). However the proximity of the mobile phone to the mother's body when not in use was not found as a risk factor. Conclusion: The etiology of CAKUT is multifactorial. Our results suggest that prolonged phone call and higher EMF exposure during pregnancy increases the risk of CAKUT in the offspring.

BACKGROUND: Hyperchloremia is often encountered due to the frequent administration of intravenous fluids in critically ill patients with conditions such as shock or hypotension in the pediatric intensive care unit, and high serum levels of chloride are associated with poor clinical outcomes. OBJECTIVES: This study aimed to determine the association between hyperchloremia and in-hospital mortality in pediatric patients with major trauma. DESIGN AND SETTING: This retrospective cohort study was conducted at a tertiary university hospital in Turkey. METHODS: Data were collected between March 2020 and April 2022. Patients aged 1 month to 18 years with major trauma who received intravenous fluids with a concentration > 0.9% sodium chloride were enrolled. Hyperchloremia was defined as a serum chloride level > 110 mmol/L. Clinical and laboratory data were compared between the survivors and nonsurvivors. RESULTS: The mortality rate was 23% (n = 20). The incidence of hyperchloremia was significantly higher in nonsurvivors than in survivors (P = 0.05). In multivariate logistic analysis, hyperchloremia at 48 h was found to be an independent risk factor for mortality in pediatric patients with major trauma. CONCLUSIONS: In pediatric patients with major trauma, hyperchloremia at 48-h postadmission was associated with 28-day mortality. This parameter might be a beneficial prognostic indicator.

OBJECTIVE: The number of admissions for severe diabetic ketoacidosis (DKA) in children with newly diagnosed type 1 diabetes (T1D) increased during the coronavirus disease 2019 pandemic. We aimed to investigate whether there has been a change in this situation in recent years. MATERIALS AND METHODS: All children with T1D who were diagnosed in our tertiary hospital between 2019 and 2023 were included. Plasma insulin, C-peptide, hemoglobin A1c (HbA1c), and antibodies against thyroid peroxidase, thyroglobulin, insulin, islet cell, glutamic acid decarboxylase, tissue transglutaminase IgA, and endomysium IgA were measured. RESULTS: The frequency of moderate-severe acidosis at admission, which increased after pandemic period compared to the pre-pandemic period, returns to its previous levels over time but still shows a statistical difference compared to the pre-pandemic period (P = .012). Age, blood gas pH and HCO3 level, C-peptide, HbA1c, and length of stay of children at the time of admission were compared year by year (years 2019-2023). No statistical differences were observed (P = .509, P = .181, P = .069, P = .469, P = .346, P = .946), respectively. A significant difference was observed in venous glucose (P .001) and insulin (P = .001) according to years. Also, no significant difference was found about the degree of acidosis according to age (P = .334). CONCLUSION: Although the frequency of DKA in children with newly-diagnosed T1D increased in the first years of the pandemic, it has been decreasing over t.
RESUMO
Introduction: Malnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies. Material and Method: In this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined. Results: Of the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48â h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48â h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024). Conclusion: Timely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48â h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score.
RESUMO
OBJECTIVE: A few pediatric studies were present which focused on renal replacement therapy used for critically ill children. This research aimed to determine the ratio of utilization of intermittent hemodialysis, continuous renal replacement therapy, and peritoneal dialysis, and to study the properties and outcomes of critically ill pediatric patients who underwent renal replacement therapy. METHODS: Critically ill children admitted to the intensive care unit and received renal replacement therapy from February 2020 to May 2022 were included. The children were divided into three groups: hemodialysis, continuous renal replacement therapy, and peritoneal dialysis. RESULTS: A total of 37 patients (22 boys and 15 girls) who received renal replacement therapy met the criteria for this study. Continuous renal replacement therapy was used in 43%, hemodialysis in 38%, and peritoneal dialysis in 19%. In all, 28 (73%) children survived and 9 (27%) died in intensive care unit. The mean systolic blood pressure was significantly lower among children who received continuous renal replacement therapy (p<0.001). The need for inotropic medications and a higher PRISM III score were found to be the greatest indicators of mortality. CONCLUSION: The outcome of children receiving renal replacement therapy seems to be related to their needs for vasoactive drugs and the severity of the underlying disease in the continuous renal replacement therapy group relative to the other groups.

BACKGROUND: This study evaluated of clinical characteristics, outcomes, and mortality risk factors of a severe multisystem inflammatory syndrome in children admitted to a the pediatric intensive care unit. METHODS: A retrospective multicenter cohort study was conducted between March 2020 and April 2021 at 41 PICUs in Turkey. The study population comprised 322 children diagnosed with multisystem inflammatory syndrome. RESULTS: The organ systems most commonly involved were the cardiovascular and hematological systems. Intravenous immunoglobulin was used in 294 (91.3%) patients and corticosteroids in 266 (82.6%). Seventy-five (23.3%) children received therapeutic plasma exchange treatment. Patients with a longer duration of the PICU stay had more frequent respiratory, hematological, or renal involvement, and also had higher D-dimer, CK-MB, and procalcitonin levels. A total of 16 patients died, with mortality higher in patients with renal, respiratory, or neurological involvement, with severe cardiac impairment or shock. The non-surviving group also had higher leukocyte counts, lactate and ferritin levels, and a need for mechanical ventilation. CONCLUSIONS: In cases of MIS-C, high levels of D-dimer and CK-MB are associated with a longer duration of PICU stay. Non-survival correlates with elevated leukocyte counts and lactate and ferritin levels. We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality. IMPACT: MIS-C is a life-threatening condition. Patients need to be followed up in the intensive care unit. Early detection of factors associated with mortality can improve outcomes. Determining the factors associated with mortality and length of stay will help clinicians in patient management. High D-dimer and CK-MB levels were associated with longer PICU stay, and higher leukocyte counts, ferritin and lactate levels, and mechanical ventilation were associated with mortality in MIS-C patients. We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality.

BACKGROUND: Acute kidney injury (AKI) is a serious clinical condition in critically ill children and is associated with worse outcomes. A few pediatric studies focused on the risk factors of AKI. We aimed to identify the incidence, risk factors, and outcomes of AKI in the pediatric intensive care unit (PICU). PATIENTS AND METHODS: All the patients admitted to PICU over a period of 20 months were included. We compared both groups the risk factors between AKI and non-AKI. RESULTS: A total of 63 patients (17.5%) of the 360 patients developed AKI during PICU stay. The presence of comorbidity, diagnosis of sepsis, increased PRISM III score, and positive renal angina index were found to be risk factors for AKI on admission. Thrombocytopenia, multiple organ failure syndrome, the requirement of mechanical ventilation, use of inotropic drugs, intravenous iodinated contrast media, and exposure to an increased number of nephrotoxic drugs were independent risk factors during the hospital stay. The patients with AKI had a lower renal function on discharge and had worse overall survival. CONCLUSIONS: AKI is prevalent and multifactorial in critically sick children. The risk factors of AKI may be present on admission and during the hospital stay. AKI is related to prolonged mechanical ventilation days, longer PICU stays, and a higher mortality rate. Based on the presented results early prediction of AKI and consequent modification of nephrotoxic medication may generate positive effects on the outcome of critically ill children.
RESUMO
Background While lactate clearance (LC) has already been shown as a prognostic indicator in clinical studies, its certain character needs to be defined in pediatric trauma. This research aimed to evaluate the correlation between early lactate clearance and mortality in pediatric trauma.Patients and methods A retrospective cohort study was conducted in a university hospital. Repeated LC was measured at admission, at the 2nd, 6th, and 12th hours post-admission. The association of lactate clearance with mortality was analyzed and using receiver operating characteristic (ROC) to determine the threshold levels of lactate clearance and also logistic regression analysis was performed to determine whether LC was an independent risk factor.Results Seventy-eight patients were included and overall mortality was 13%. LC values of the non-survivors was significantly lower than survivors for LC0-2 h (28.60±14.26 vs 4.64±15.90), LC0-6 h (46.63±15.23 vs 3.33±18.07), LC0-12 h (56.97±15.53 vs 4.82±22.59) (p:<0.001, p:<0.001 and p:<0.001, respectively). Areas under the curve of lactate clearance at the 2nd, 6th, and 12th hours after therapy start were a significant predictor for mortality (p:<0.001, p:<0.001, and p:<0.001, respectively). Threshold values of LC were 12.9, 19.5 and 29.3%, respectively.Conclusion Lactate clearance was a beneficial tool to estimate outcomes of pediatric trauma. Poor lactate clearance was a significant marker for poor prognosis.

BACKGROUND: A significant number of children are injured by or die from firearm-related incidents every year, although there is a lack of global data on the number of children admitted to pediatric emergency departments (PEDs) and pediatric intensive care units (PICU) with firearm injuries. This study is the most comprehensive analysis of firearm injuries sustained by children in Turkey to date. METHODS: This multicenter, retrospective, cohort study was conducted between 2010 and 2020 with the contributions of the PEDs, PICUs, intensive care units, and surgery departments of university hospitals and research hospitals. RESULTS: A total of 508 children were admitted to hospital with firearm-related injuries in the research period, although the medical records of only 489 could be obtained. Of the total admissions to hospitals, 55.0% were identified as unintentional, 8.2% as homicide, 4.5% as self-harm, and 32.3% as undetermined. The Glasgow Coma Scale (GCS) and ventilation support were found to be the most significant predictors of mortality, while head/neck injury, length of stay (LOS) in the hospital and surgical interventions were found to be the most significant predictors of disability. The overall mortality of firearm-related injuries was 6.3%, and the mortality for children admitted to the PICU was 19.8%. The probability of disability was calculated as 96.0% for children hospitalized with firearm injuries for longer than 75 days. CONCLUSIONS: Head/neck injury, LOS in the hospital, and surgical interventions were found to be the most significant parameters for the prediction of disability. Hospitalization exceeding 6 days was found to be related to disability.

BACKGROUND: Thrombocytopenia-associated multiple organ failure (TAMOF) causes a high ratio of mortality in pediatric patients. Only anticoagulants and profibrinolytic molecules can be replaced with plasma infusion (PI), while therapeutic plasma exchange (TPE) eliminates antifibrinolytic and thrombogenic molecules and charges inadequate anticoagulants and profibrinolytic molecules. This study aims to compare the efficacy of plasma exchange to plasma infusion in pediatric TAMOF patients. METHODS: Twenty-seven patients with TAMOF were included and the efficacy of PI and TPE was compared. The demographic data, admission laboratory values, Pediatric Logistic Organ Dysfunction (PELOD) scores before the beginning of treatment and PELOD at the end of treatment, and outcomes of groups were compared. RESULTS: Sixteen children were in the plasma infusion group, eleven children were in the plasma exchange group. The total mortality rate of all patients was 37%. The PELOD scores were significantly reduced on the 5th day of treatment in both groups and also PELOD scores were significantly higher on the 5th day of study in the non-survivor group (p: < 0.001). The fifth day of PELOD scores and ferritin had a significant effect on mortality (OR: 1.85, 95% CI: 1.02-2.69; p: 0.04, OR: 1.43, 95% CI: 0.97-2.03; p: 0.05). The overall mortality ratio was not different between TPE and PI groups (p: 0.12). CONCLUSIONS: Although there was no difference in mortality rates in children who received plasma exchange compared to children who received plasma infusion, mechanical ventilation and length of pediatric intensive care unit (PICU) day were shorter in the TPE group. The small patient population may be the major cause for the lack of significant statistical difference.

BACKGROUND: The main goal of septic shock therapy is to keep hemodynamic parameters in the normal range for adequate tissue perfusion. Persistent lactic acidemia has increased mortality. We evaluate the association between vasoactive-inotropic score (VIS) and lactate clearance (LC) to predict mortality of septic shock in children. METHODS: This is a retrospective study of consecutive septic shock in children admitted to the pediatric intensive care unit. Vital signs, laboratory values, and VIS were obtained at admission and the 6th hour of hospitalization. LC was calculated at the 6th hour. The associations between LC and VIS were evaluated using univariate and multivariate analysis. Receiver operating characteristic analysis was used to describe the cutoff values of LC and VIS. RESULTS: Eighty-two children, age 82.3 ± 59.8 months, were included, with an overall lactate clearance of 29 ± 26%, and a mortality rate of 25.6%. The optimal cutoff value of LC was 20%. Children with LC ≥ 20% compared with LC < 20% had a lower VIS [(21.41 ± 8.36) vs. (27.48 ± 10.11) (p: 0.009)]. In multivariate comparison, PELOD score and VIS were significantly associated with 6-hour lactate clearance < 20% but VIS at 6 hours had a significant inverse relationship with LC < 20%. The cutoff for VIS was ≥ 16.2 for prognosticating the 6-hour LC and the high VIS group had a significantly lower LC and higher mortality ratio than the low VIS group. CONCLUSIONS: High VIS was associated with lower lactate clearance and has been described as a predictor of greater mortality among septic shock in children.

BACKGROUND: The aim was to evaluate the epidemiological, clinical, laboratory, and radiologic data of children with SARS-CoV-2 positivity by polymerase chain reaction (PCR) together with treatment strategies and clinical outcomes and to evaluate cases of multisystem inflammatory syndrome in children (MIS-C) in this population. METHODS: This was a multicenter retrospective observational cohort study performed in the pediatric emergency departments of 19 tertiary hospitals. From March 11, 2020, to May 31, 2021, children who were diagnosed with confirmed nasopharyngeal/tracheal specimen SARS-CoV-2 PCR positivity or positivity for serum-specific antibodies against SARS-CoV-2 were included. Demographics, presence of chronic illness, symptoms, history of contact with SARS-CoV-2 PCR-positive individuals, laboratory and radiologic investigations, clinical severity, hospital admissions, and prognosis were recorded. RESULTS: A total of 8886 cases were included. While 8799 (99.0%) cases resulted in a diagnosis of SARS-CoV-2 with PCR positivity, 87 (1.0%) patients were diagnosed with MIS-C. Among SARS-CoV-2 PCR-positive patients, 51.0% were male and 8.5% had chronic illnesses. The median age was 11.6 years (IQR: 5.0-15.4) and 737 (8.4%) patients were aged <1 year. Of the patients, 15.5% were asymptomatic. The most common symptoms were fever (48.5%) and cough (30.7%) for all age groups. There was a decrease in the rate of fever as age increased (p < 0.001); the most common age group for this symptom was <1 year with the rate of 69.6%. There was known contact with a SARS-CoV-2 PCR-positive individual in 67.3% of the cases, with household contacts in 71.3% of those cases. In terms of clinical severity, 83 (0.9%) patients were in the severe-critical group. There was hospital admission in 1269 (14.4%) cases, with 106 (1.2%) of those patients being admitted to the pediatric intensive care unit (PICU). Among patients with MIS-C, 60.9% were male and the median age was 6.4 years (IQR: 3.9-10.4). Twelve (13.7%) patients presented with shock. There was hospital admission in 89.7% of these cases, with 29.9% of the patients with MIS-C being admitted to the PICU. CONCLUSION: Most SARS-CoV-2 PCR-positive patients presented with a mild clinical course. Although rare, MIS-C emerges as a serious consequence with frequent PICU admission. Further understanding of the characteristics of COVID-19 disease could provide insights and guide the development of therapeutic strategies for target groups.

OBJECTIVES: The aim of the present study was to determine the prognostic value of thrombocytopenia, platelet indices (MPV/PLT and PDW/PLT) in children with septic shock. BACKGROUND: Septic shock is one of the major causes of mortality among children worldwide. METHODS: A retrospective analysis was made of children admitted to the pediatric intensive care unit between November 2010 and December 2019. Two hundred four children were included; they were diagnosed with septic shock according to the international pediatric sepsis consensus conference criteria. The MPV/platelet ratio and PDW/platelet ratios were estimated as the MPV and PDW values divided by the platelet count on the first three days of hospitalization. The clinical outcome was 28-day mortality. RESULTS: MPV/PLT and PDW/PLT ratios were found to be significantly higher in the non-survivors than survivor (p≤0.001). In the multivariate logistic regression analysis, higher MPV/platelet ratios at 72h (OR: 7.41; 95% CI: 1.25-43.7; p=0.027) and PDW/platelet ratios at 72h (OR: 2.9; 95% CI: 1.13-7.50; p=0.027) were significant risk factors for mortality. CONCLUSIONS: Platelet indices are useful laboratory parameters in septic shock. MPV/PLT and PDW/PLT ratios can be promising reliable markers for 28-day mortality in children with septic shock (Tab. 4, Fig. 1, Ref. 29).

OBJECTIVE: This study aims to investigate modes of transmission and clinical features of coronavirus disease 2019 in healthcare workers in pediatric intensive care units. MATERIALS AND METHODS: This multicenter descriptive study was conducted between March and November 2020. Patient demographics, clinical characteristics, origin of coronavirus disease 2019, treatment modalities, and loss of workdays were recorded. RESULTS: Seven hundred and sixty-eight healthcare workers from 16 pediatric intensive care units were enrolled and 114 (14.8%) healthcare workers with a mean age of 29.7 ± 6.7 years became coronavirus disease 2019 patients. Seventy-six (66.7%) patients were female. Approximately half (54.3%) of the patients were physicians, 34.2% were nurses, and 11.4% were ancillary staff. Transmission was deemed to occur through patient contact in 54.3% of the patients. Comorbid illness was present 10.5% of the patients. Transmission occurred during endotracheal intubation in 21%, cardiopulmonary resuscitation in 9.6%, and non-invasive ventilation in 12.2% of patients, while transmission was a result of multiple possible procedures in 43.8%. Intensive care admission was needed for 13.1% of the patients. Five patients needed oxygen by cannula, 7 needed oxygen with a non-rebreathing mask, 5 needed high-flow nasal cannula support, 5 needed non-invasive ventilation, and 3 needed invasive mechanical ventilation. Fortunately, no infected healthcare workers died. CONCLUSION: Coronavirus disease 2019 in healthcare workers is a significant problem in pediatric intensive care units. Transmission seems to occur particularly frequently during patient care procedures such as intubation, ventilation and aerosol therapy, which highlights the importance of proper use of full sets of personal protective equipment during all procedures during care of coronavirus disease 2019 patients.
RESUMO
OBJECTIVE: The aim of this study is to compare the screen time and digital gaming habits of Turkish children before and during the coronavirus disease 2019 (COVID-19) pandemic. MATERIAL AND METHODS: This cross-sectional descriptive study was carried out in a university hospital between May 7, 2020 and June 27, 2020. Healthy children aged 3-10 years who applied to the pediatrics clinics for outpatient care were included in the study. A structured survey was applied to the parents who agreed to participate. RESULTS: A total of 253 children were included in the study. It was found that the ratio of children with screen time of ≥1 hour during the pandemic was significantly higher than before the pandemic (p<0.001). It was determined that the ratio of children watching both adult and children's programs increased during the pandemic (p<0.001). The ratio of children playing digital games during the pandemic was also found to be increased significantly compared with that before the pandemic (p<0.001). CONCLUSION: This study demonstrated that screen and digital gaming time increased independently of sociodemographic characteristics during the COVID-19 pandemic compared with before the pandemic.
RESUMO
Doksöz Ö, Nacaroglu HT, Ceylan G, Çelegen M, Asik-Nacaroglu S, Can D, Mese T, Ünal N. The evaluation of right and left ventricular functions in children with episodic wheezing exposed to environmental tobacco smoke. Turk J Pediatr 2017; 59: 42-48. The objective of this study is to examine the right and left ventricular functions in children with episodic wheezing at the ages of 1-3 exposed to environmental tobacco smoke (ETS). Thirty-two children monitored at the Pediatric Allergy and Immunology Department of a Research and Training Hospital with the diagnosis of episodic wheezing were included. The prospective assessment of the patients was performed between May 2013 and February 2014. Twenty-five children with episodic wheezing not exposed to ETS formed the control group. The two groups were compared by conducting transthoracic two-dimensional and tissue Doppler echocardiography (TDE) examination in all of the cases. The average age of the study group (24 boys, 8 girls) was 33.1 ± 8.8 months, the average age of the control group (18 boys, 7 girls) was 31.9 ± 11.9 months. There was no statistically significant difference between the two groups in terms of age, gender, weight, height, and body mass index values. There was no statistically significant difference between the two groups for the right and left ventricular systolic and diastolic functions in the conventional echocardiographic measurements, and for the measurements of TDE. Limited number of patients is a major limitation of the study. These results should be supported by more comprehensive studies.

OBJECTIVE: Our primary aim was to determine the short-term effects of a ketogenic diet on cardiac ventricular function in patients with refractory epilepsy. METHODS: Thirty-eight drug-resistant epileptic patients who were treated with a ketogenic diet were enrolled in this prospective study. Echocardiography was performed on all patients before beginning the ketogenic diet and after the sixth month of therapy. Two-dimensional, M-mode, color flow, spectral Doppler, and pulsed-wave tissue Doppler imaging measurements were performed on all patients. RESULTS: The median age of the 32 patients was 45.5 months, and 22 (57.8%) of them were male. Body weight, height, and body mass index increased significantly at the sixth month of therapy when compared with baseline values (P < 0.05). Baseline variables assessed by conventional M-mode echocardiography showed no significant difference at month 6 (P > 0.05). Doppler flow indices of mitral annulus and tricuspid annulus velocity of patients at baseline and month 6 showed no significant differences (P > 0.05). Tricuspid annular E/A ratio was lower at month 6 (P < 0.05). Although mitral annulus tissue Doppler imaging studies showed no significant difference (P > 0.05), there was a decrease in Ea velocity and Ea/Aa ratio gathered from tricuspid annulus at month 6 compared with baseline (P < 0.05). CONCLUSION: A 6-month duration ketogenic diet does not impair left ventricular functions in children with refractory epilepsy; however, it may be associated with a right ventricular diastolic dysfunction.
