The effect of middle and high school students' emotional eating behavior on obesity.

AIM: This study was conducted to determine the effect of middle and high school students' emotional eating behavior on obesity. METHOD: A descriptive, correlational, and cross-sectional study design was used. The sample consisted of 267 students studying in 5th, 6th, 7th, 8th, 9th, 10th, 11th, and 12th grades. Data were collected using a Child Information Form and the Emotional Eating Scale. The researchers measured the students' height and weight and calculated their body mass indices (BMI), and BMI percentiles were evaluated according to age and gender. Percentage calculations, mean scores, Spearman correlation analysis, Pearson's correlation analysis, and multiple regression analysis were used in the analysis of the data. RESULTS: Of the students participating in the study, 54.7% were girl and 45.3% were boy. It was determined that 28.4% of the students were overweight and obese. As a result of multiple regression analysis, it was determined that students' emotional eating behavior explained 25% of obesity (p < 0.001). It was found that anxiety-anger- frustration, one of the subscales of the emotional eating scale, was the only variable that significantly predicted students' obesity status (ß = 0.387). Emotional eating significantly predicted the obesity status of boy and girl students (p < 0.001). CONCLUSION: In this study, it was concluded that students' emotional eating behavior affected obesity. IMPLICATIONS FOR PRACTICE: In line with these results, it is recommended that studies on other variables that may predict the effect of students' emotional eating behavior on obesity should be conducted and that nurses should contact schools to conduct emotional eating behavior screenings and provide emotional eating education for students who exhibit emotional eating behavior.

Characteristics of adverse reactions due to subcutaneous allergen immunotherapy applied between 2011-2021: Single center experience.

Introduction: The aim of this study was to elucidate the incidence of local, large local and systemic reactions after subcutaneus immunotherapy (SCIT) injections in our clinic and to determine the characteristic features of these adverse reactions. Materials and Methods: A total of 6000 SCIT injections administered to 163 patients between January 2011 and December 2021 were retrospectively evaluated. The study population consisted of patients with allergic rhinoconjunctivitis who underwent SCIT due to pollen, house dust mite or cat allergy, or patients who underwent SCIT due to venom allergy. Demographic characteristics of the patients, diagnoses, allergen sensitivities, immunotherapy protocol applied, adverse reactions, and the characteristics of these reactions were recorded. Result: Totally, 163 patients with a mean age of 36.8 ± 12.7 years were enrolled in this research. Sex distribution was as follows: 55.2% (n= 90) were females. During the study, 218 allergic reactions were detected in 83 patients. The incidence of adverse reactions per injection was 3.6%. The probability of developing an adverse reaction in a patient during the entire subcutaneous immunotherapy was 53.9%. Of the adverse reactions that developed, 94 (43.1%, n= 47) were observed locally while 56 (25.7%, n= 40) were large local reactions, and 68 (31.2%, n= 30) were systemic. Incidence of adverse reactions per injection were 1.5%, 0.9%, and 1.1% for local reaction, large local reaction, and systemic reaction, respectively. Conclusions: The results of this analysis elaborated that subcutaneous immunotherapy is a safe and tolerable treatment modality. However, before initiating treatment, the benefits and risks should be evaluated. The risk of systemic reactions is quite low, but fatal anaphylaxis can occur, so physicians need to be aware of the potential risks.

Rapid drug desensitization to taxanes: a descriptive study from Turkey.

AIM: To present the characteristics of drug hypersensitivity reactions (DHRs) among taxane recipients with non-small cell lung carcinoma (NSCLC), and to describe the results of rapid drug desensitization (RDD). METHODS: A retrospective cross-sectional study included 45 patients who were treated with taxane for NSCLC and were found to be hypersensitive to taxane. All patients were administered the standard 3-bag, 12-step RDD protocol following the development of DHR. RDD success was evaluated separately for each cycle, and successful RDD was defined as the completion of the cycle with application of 12 steps of the desensitization protocol and the absence of early and/or late reactions afterwards. RESULTS: Among 45 patients hypersensitive to taxane 43 (95.6%) successfully received taxane cycles with desensitization. Failed RDD occurred in only 2 (4.4%) patients. The total number of desensitization cycles was 183, of which 181 (98.9%) were successful. The mean age of patients with successful desensitization was 59.42 ± 10.48 years and 37 (86.0%) of them were male. CONCLUSION: RDD is a reliable procedure that enables effective administration and completion of first-line taxane treatments in taxane-sensitive patients.

Platin desensitizations in thoracic malignancies and risk factors for breakthrough reactions.

Although platin desensitization is a safe and effective alternative for patients with hypersensitivity reactions (HSRs), sometimes breakthrough reactions (BTRs) can be encountered. However, data about the risk factors for BTRs are limited. The aim of this study is to define the outcomes of desensitization, the characteristics of BTRs, and to identify the risk factors for BTRs with platins in thoracic malignancies. This is a retrospective report of patients with thoracic malignancies who underwent platin desensitization. Patients' demographics, initial HSR characteristics, skin test results, desensitization outcomes, and BTR characteristics were recorded. Thirty-three lung cancer and 14 malignant pleural mesothelioma (MPM) patients were included in the study. The culprit drug was cisplatin in 29 and was carboplatin in 18 patients. Skin test positivity was 43.5% with cisplatin, 50% with carboplatin, and it was found to be higher if the interval between the initial HSR and skin testing (ST) was ˃20 days (p = 0.027). One hundred and five desensitization courses were performed. Twenty-two patients had 33 BTRs. Skin test positivity was higher in the BTR-positive group (p = 0.025). BTRs (18.2%; n = 6) were more severe than initial HSR. In the case of epinephrine administration during initial HSR, epinephrine administration during the first BTR was found to be more (p = 0.036). The target dose was achieved in 92.4% of desensitization courses. The number of previous platin infusions ≥10 was found to be an independent risk factor for BTR development (p = 0.036 OR:17.641, 95% CI: 1.211-256.971). Identification of risk factors for BTR will guide appropriate management and desensitization approaches for platin HSRs.

Successful desensitization under antihistamine suppression in a case with urticaria due to osimertinib.

INTRODUCTION: Osimertinib is an approved therapy for patients with a Thr790met (T790M) mutation diagnosed with non-small cell lung cancer (NSCLC) that progresses during epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy. However, in 7-13% of patients, drug-related side effects lead to discontinuation of osimertinib treatment. In such cases, osimertinib desensitization is a treatment option that can be considered. CASE REPORT: A 59-year-old female patient, who was followed up with the diagnosis of stage 4 NSCLC, was consulted to the allergy clinic because of urticaria. The patient developed urticaria plaques 20 h after the third dose of osimertinib tablet. MANAGEMENT & OUTCOME: With the diagnosis of osimertinib-induced urticaria, desensitization was planned for the patient. Treatment was started with a dose of 0.1 mg/day osimertinib. The procedure was completed in approximately 50 days, and a dose of 80 mg/day was reached with antihistamine suppression. DISCUSSION: Here, a successful osimertinib desensitization in a patient with a history of osimertinib-related type 1 allergic reaction is reported. Osimertinib desensitization is a treatment option that should be considered in cases where treatment has to be ceased due to drug-related side effects.

Impact of antenatal corticosteroid exposure on thymus size in premature infants.

BACKGROUND: This study examined the effect of corticosteroids on the thymic index (TI) and the thymus/weight index (TWI) in infants exposed to antenatal corticosteroids (ACS). METHODS: This prospective study was conducted between August 2014 and October 2018. A thymus ultrasound was performed to assess thymus size on the second day of life. Thymus size was assessed as TI and TWI. RESULTS: In total, 167 neonates (≤34 weeks gestation)  constituted the study population, including 94 ACS-exposed infants and 73 untreated infants. The treatment group exhibited significantly lower birth weight and significantly shorter birth length than the ACS (-) group. Therefore, TI was smaller in the treatment group than in the untreated group (6.96 ± 4.05 cm3 vs. 5.64 ± 3.39 cm3). The TWI was 3.69 ± 1.8 cm3/kg in the ACS (-) group versus 3.32 ± 1.56 cm3/kg in the ACS (+) group. The median anteroposterior diameter of the right lobe was 1.33 cm (range, 0.45-2.40) in the ACS (-) group compared to 1.15 cm (range, 0.47-2.40) in the ACS (+) group. The median anteroposterior diameter of the left lobe was 1.40 cm (range, 0.43-2.20) in the ACS (-) group and 1.19 cm (range, 0.32-2.36) in the ACS (+) group. The median largest sagittal area was 2.64 cm2 (range, 0.5-5.46) in the ACS (-) group versus 2.20 cm2 (range, 0.55-5.90) in the ACS (+) group. CONCLUSION: We found that TWI was not significantly changed by ACS exposure in premature infants.

COVID-19 in patients with severe asthma using biological agents.

As the COVID-19 pandemic continues, case reports have been published where patients with severe asthma using biological agents survived with a mild course of illness and encouraged the continuation of biological therapies in patients with severe asthma. However, contrary to previous information, a more severe course of COVID-19 has recently been reported in severe asthmatics using biological therapy compared to the general population. To evaluate the COVID-19 rate and disease severity in severe asthmatics using biological agents. A retrospective study was conducted in patients with severe asthma treated with biological agents. Data concerning whether the subjects had contracted COVID-19 and the severity of the disease were evaluated. Eihgty-four severe asthmatics using biological agents (omalizumab or mepolizumab) aged 48.3 ± 10.6 years (mean ± standard deviation) with female/male ratio: 53 (63.1%)/31 (36.9%) were included in the study. Among participants 13 (15.5%) had contracted COVID-19. The course of COVID-19 was mild in five (38.5%) and moderate in eight patients (61.5%), while none of the patients had a severe course of COVID-19. Mechanical ventilation or intensive care follow-up was not required in any of the six patients (46.2%) who were treated as inpatients. All participants survived COVID-19 in full recovery and no deaths occurred in the cases. A higher rate of COVID-19 was found in patients with severe asthma using biologics compared to those reported in previous reports. However, all patients with COVID-19 have a mild to moderate disease course.

Real-life adherence to subcutaneous immunotherapy: What has changed in the era of the COVID-19 pandemic.

BACKGROUND: Allergen immunotherapy (AIT) must be continued for 3 years, to achieve a long-term modifying effect. Adherence is a key to ensure effectiveness. The objective of this study was, first of all, to evaluate the adherence with subcutaneous immunotherapy (SCIT) and to identify the main causes of SCIT withdrawal in real-life practice in our clinic. Secondly, we also aimed to investigate to what extent the COVID-19 pandemic altered our SCIT receiving patients' treatment adherence behaviors and the factors that affected their decisions. METHODS: Retrospective analysis of the medical records of patients ages ≥18 years, who had started SCIT in January 2014 or later until September 2020 in our department for the diagnosis of allergic rhinitis, allergic asthma or venom allergy, were included in the study. Adherence was determined as the accomplishment of 3 years of SCIT. RESULTS: A total of 124 patients (72 female [58.1%]; median age, 35 [19-77] years) were included. The adherence rate to SCIT in our tertiary center's real-life setting was 56.25% with a follow-up duration of 3 years before COVID-19 pandemic. Dose modification, defined as reducing patient's planned SCIT dose due to a systemic allergic/large local reaction or missed injection, and its frequency, which is the number of dose adjustments done throughout the SCIT, was found to be the only factor related to nonadherence. But with the pandemic only in 6 months, among 63 patients receiving SCIT, 15 patients (23.81%) dropped out, and the most common reason was fear of being infected with COVID-19 virus during receiving SCIT in hospital (93.33%). The only independent predictor of drop-out during the COVID-19 pandemic was short duration of AIT (p = 0.012). When we compare the dropped-out cases before and after the start of pandemic, AIT duration was significantly shorter in pandemic period (p = 0.005). CONCLUSION: Adherence rate to SCIT in our real-world setting study was 56.25% before the COVID-19 pandemic. Our results indicated that patients requiring dose modification were more prone to be non-adherent. Approximately one quarter of patients dropped-out with the start of pandemic, almost all due to fear of being infected during receiving SCIT in hospital. Since short SCIT follow-up time was found to be the only risk factor for drop-out during the COVID-19 pandemic, we believe that patients who are in the early phases of their treatment should be observed more closely and their concerns should be answered by their doctors.

Psychometric properties of the Turkish version of the Child Three-Factor Eating Questionnaire for primary and secondary school students.

OBJECTIVE: This study aims to evaluate the validity and reliability of the Turkish version of the Child Three-Factor Eating Questionnaire for primary and secondary school students. DESIGN: A methodological, descriptive and correlational study design was adopted. SETTING: The study was conducted in the western and central regions of Turkey. PARTICIPANTS: This methodological-descriptive-correlational study was conducted with 351 children between July 2018 and August 2018. The mean age of children is 10·74 ± 1·79 (8-14). RESULTS: The scale consists of seventeen items and three sub-dimensions (restraint, uncontrolled eating and emotional eating), which explained 52·88 % of the total variance. All the factor loadings were >0·40 in both exploratory factor analysis and confirmatory factor analysis (CFA). In CFA, all of the fit indices were >0·85, and root mean square error of approximation was <0·08. For the whole of the scale, Cronbach's α was 0·81 and it was found that Cronbach's α values of all sub-dimensions were >0·70. CONCLUSIONS: The results of the study show that the Child Three-Factor Eating Questionnaire for primary and secondary school students is a valid and reliable measurement tool for Turkish sampling.

A New Perspective for Infantile Hepatic Hemangioma in the Age of Propranolol: Experience at Baskent University.

Propranolol was first used in 2008 to treat hemangioma; its efficacy and safety have since changed the classical treatment indications. Infantile hepatic hemangioma presents as a spectrum of clinical conditions varying from simple asymptomatic lesions to lethal complications. Tufted hemangioma and Kaposiform hemangioendothelioma are congenital vascular tumors that lead to Kasabach-Merritt syndrome. Hemangiomas, like pure arteriovenous malformations, can cause hyperdynamic heart failure, and diffuse nodular-type hemangiomas can present with hypothyroidism. Respiratory problems and hepatic failure can be associated with diffuse nodular-type liver hemangiomas. There is a spectrum of approaches to management, varying from "watchful waiting" to liver transplant. In the age of propranolol, there has been a prominent change in the infantile hepatic hemangioma treatment algorithm. Our suggestion is early treatment with 3 mg/kg/day propranolol plus 1.0 to1.5 mg/kg/day prednisolone in all patients. This protocol is the most effective strategy for type 3 infantile hepatic hemangioma. Approximately one-third of patients with abdominal compartment syndrome in the era before propranolol treatment required liver transplant; this new treatment obviates transplant for many of these patients.

A different cause for respiratory disorder in children: cases with pulmonary Langerhans cell histiocytosis.

BACKGROUND AND AIMS: In children, complaints of a respiratory disorder are very frequent. Etiology of respiratory illness is a broad spectrum that varies from a simple viral infection to a malignant disorder. Pulmonary Langerhans cell histiocytosis (PLCH) is one of these entities and it is truly rare in children. The aim of this study is to evaluate our patients with PLCH. METHODS: Patients who had been diagnosed with PLCH were retrospectively evaluated. Features of medical history, onset of the complaints, date of the diagnosis, chest X-Ray and computed tomography (CT) findings, histopathology and other laboratory investigations were considered. RESULTS: There were four cases with PLCH. All of them were male, ages were between 5 months and 16 years. In three cases, major complaints were chronic respiratory problems whereas in one of them there was acute respiratory distress beginning with cough and leading to pneumothorax. In all of the cases, multisystemic involvement was prominent. The diagnosis was proven by histopathology in all of the cases. In two children with smaller age, skin involvement was detected. Time from complaint to diagnosis was minimum 3 months and maximum 3 years. CONCLUSION: PLCH is a rare disorder in children. Pulmonary involvement is generally a component of systemic involvement but in many cases it might have been detected with early respiratory complaints. So, children with chronic respiratory problems should be carefully evaluated and should be followed up for rare entities like PLCH.

Spleen Salvaging Treatment Approaches in Non-parasitic Splenic Cysts in Childhood.

The aim of this study was to evaluate our experience with primary non-parasitic splenic cysts (NPSC) which are relatively rare in children and consist almost exclusively of single case reports or small case series in the literature. The medical records of all patients who presented to our clinic with NPSC between 2005 and 2015 were evaluated retrospectively. There were 22 children whose ages ranged from 2 months to 14 years (mean 9.2 ± 4.7 years). The size of the cysts was in the range of 5 to 200 mm (mean 55.4 ± 48.2 mm). Ten patients underwent surgery for splenic cysts. Partial splenectomy (n = 2), total cyst excision (either open n = 4 or laparoscopically n = 1), and total splenectomy (n = 3) were performed. The non-operated patients were asymptomatic and followed with ultrasound (US). The follow-up period in non-operated patients ranged from 6 months to 5 years (mean 2.27 ± 1.29 years). Complete regression was observed in four (33 %) non-operated patients. The regressed cyst measurements were 10, 16, 30, and 40 mm, respectively. Approximately half of the NPSC is diagnosed incidentally. Small (<5 cm) asymptomatic cysts should be under regular follow-up with US/physical examination for regression. If surgery is required, we prefer open cyst excision as it gives excellent results and preserves splenic immune function.

Evaluation of brain perfusion in Alzheimer disease with perfusion computed tomography and comparison to elderly patient without dementia.

BACKGROUND/AIM: The aim of this study was to evaluate perfusion computed tomography (PCT) findings in patients with Alzheimer disease and to compare them with those of patients without dementia. MATERIALS AND METHODS: PCT was performed in 35 patients: 20 with Alzheimer disease (mean age, 69.7 ± 5.5 years) and 15 control subjects (mean age, 67.5 ± 3.5 years). Control subjects were elderly individuals with no cognitive problems who were admitted with headaches. All PCT examinations were performed on a 4-slice CT unit. The PCT analysis software program was used to calculate regional cerebral blood flow (rCBF), regional cerebral blood volume (rCBV), regional time-to-peak (rTTP) values in the bilateral frontal, temporal, and occipital cortices, and bilateral lentiform nucleus. RESULTS: rCBF values in the bilateral frontal and temporal cortices and bilateral lentiform nucleus were significantly lower in the patients with Alzheimer disease than in the control subjects. There were no significant differences in rCBV values between Alzheimer disease and the control group. rTTP values in all cortical areas and bilateral lentiform nucleus were significantly higher in the patients with Alzheimer disease than in the control subjects. CONCLUSION: PCT is a rapid and reliable imaging modality for evaluating brain perfusion in Alzheimer disease.

Intestinal malrotation needs immediate consideration and investigation.

BACKGROUND: The aim of this study was to evaluate clinical presentation, diagnostic studies, and volvulus rate and to describe the unusual clinical clues of intestinal malrotation. METHODS: A retrospective descriptive review was carried out of all patients diagnosed with intestinal malrotation between 2002 and 2014. Patients were divided into two groups: infants (≤1 year, n = 16; group 1); and children (>1 year, n = 12; group 2). Patient demographics, clinical history, symptoms, physical examination, diagnostic work-up, operative findings and early outcome were evaluated. RESULTS: Bilious vomiting was the cardinal complaint in both groups. Unusual symptoms such as respiratory insufficiency, dehydration, afebrile convulsion, and lethargy were prominent symptoms in six patients in group 1, whereas history of frequent hospitalization due to recurrent abdominal pain and feeding intolerance were prominent in six patients in group 2. Midgut volvulus was identified in 15 patients, four of whom were in group 2. Standard Ladd's procedure was done in addition to correction of volvulus. CONCLUSION: Malrotation with or without midgut volvulus is not a rare condition and should be kept in mind for any age group. Specific signs of diagnosis are not easily identified. In the case of unusual clinical presentation, diagnosis may be delayed and can result in catastrophic consequences if intestinal perfusion occurs. Although midgut volvulus is seen most frequently in infants, risk and complication rate are high beyond 1 year of age as well, and can manifest as failure to thrive, food intolerance, and abdominal pain needing recurrent hospitalization. Diagnostic suspicion and interdisciplinary coordination are essential for timely diagnosis and surgical treatment.

Tuberous sclerosis complex; single center experience.

AIM: This study was planned with the aim of retrospectively reviewing the clinical and laboratory findings and therapies of our patients diagnosed with tuberous sclerosis and redefining the patients according to the diagnostic criteria revised by the 2012 International Tuberous Sclerosis Complex Consensus Group and comparing them with the literature. MATERIALS AND METHOD: Twenty patients diagnosed with tuberous sclerosis complex in the Pediatric Neurology Clinic were examined retrospectively in terms of clinical findings and therapies. The diagnoses were compared again according to 1998 and 2012 criteria. RESULTS: It was observed that the complaint at presentation was seizure in 17 of 20 patients and hypopigmented spots on the skin in 3 of 20 patients. On the initial physical examination, findings related with the disease were found in the skin in 17 of the patients, in the eye in 5, in the kidneys in 7 and in the brain with imaging in 17. No cardiac involvement was observed in the patients. Infantile spasm was observed in 7 of the patients who presented because of seizure (n=17), partial seizure was observed in 7 and multiple seizure types were observed in 3. It was found that sirolimus treatment was given to 9 of 20 patients because of different reasons, 7 of these 9 patients had epileptic seizures and sirolimus treatment had no effect on epileptic seizures. According to 2012 diagnostic criteria, no marked change occured in the diagnoses of our patients. CONCLUSIONS: It was observed that the signs and symptoms of our patients were compatible with the literature. Molecular genetic examination was planned for the patients who were being followed up because of probable tuberous sclerosis complex. It was observed that sirolimus treatment had no marked effect on the seizure frequency of our patients.

A Rare Complication Developing After Hematopoietic Stem Cell Transplantation: Wernicke's Encephalopathy.

Thiamine is a water-soluble vitamin. Thiamine deficiency can present as a central nervous system disorder known as Wernicke's encephalopathy, which classically manifests as confusion, ataxia, and ophthalmoplegia. Wernicke's encephalopathy has rarely been reported following hematopoietic stem cell transplantation. Herein, we report Wernicke's encephalopathy in a patient with acute myeloid leukemia who had been receiving prolonged total parenteral nutrition after haploidentical allogeneic hematopoietic stem cell transplantation. To the best of our knowledge, this is the first case reported from Turkey in the literature.

West syndrome associated with a novel chromosomal anomaly; partial trisomy 8P together with partial monosomy 9P, resulting from a familial unbalanced reciprocal translocation.

West syndrome is classified according to the underlying etiology into an acquired West syndrome, a congenital/developmental West syndrome, and West syndrome of unknown etiology. Causes of a congenital/developmental West syndrome are extensive and include chromosomal anomalies. We report on a patient carrying a derivative chromosome originating from the reciprocal unbalanced translocation t (8;9) (p11.2;p22) and presenting with macrocephaly, West syndrome, severe mental motor retardation and hypotonia. As far as we know, this is a new chromosomal anomaly associated with West syndrome.

Diagnostic value of T2*-weighted gradient-echo MRI for segmental evaluation in cerebral venous sinus thrombosis.

OBJECTIVE: We evaluated the diagnostic value of gradient-echo (GRE) imaging in patients with "cerebral venous and sinus thrombosis" (CVST). MATERIALS AND METHODS: In total, 130 thrombosed venous segment signal intensities in 45 patients with CVST were analyzed retrospectively using magnetic resonance imaging and magnetic resonance venography. RESULTS: The T2* GRE sequence had a diagnostic value for detecting acute and subacute superior sagittal sinus (SSS) thrombosis and thrombosis of the deep veins (DVs), and cortical veins (CVs; P<.05). CONCLUSIONS: The T2* GRE sequence had a high diagnostic value for detecting both acute and subacute SSS, DV, and CV thromboses.

Value of sonographic anterior-posterior renal pelvis measurements before and after voiding for predicting vesicoureteral reflux in children.

PURPOSE: Voiding cystourethrography (VCUG) is the gold standard for diagnosing vesicoureteral reflux (VUR), but it is important to minimize the use of VCUG because of the urinary catheterization and radiation exposure required. Ultrasound (US) observations suggest that pelvicalyceal dilatation varies according to the degree of bladder fullness in children with urinary tract infection. The aim of this study was to assess whether anterior-posterior (AP) measurements of the renal pelvis on US before and after voiding can be used as a screening tool while predicting the presence of VUR in children. METHODS: The subjects were toilet-trained children older than 4 years who required VCUG. Two groups were established based on the VCUG results: a VUR group of 40 kidney units (each unit defined as calyces and ureter) that exhibited different severities of reflux, and a control group of 68 kidney units unaffected by VUR. Prior to VCUG, US AP measurements of the renal pelvis of each kidney unit were recorded when the urinary bladder was full and again after bladder emptying. The change in AP measurement from before to after voiding was compared between the two groups. RESULTS: The mean change in AP measurements from before to after voiding in the VUR group was significantly greater than that in the control group (p = 0.003). CONCLUSIONS: Comparing US AP measurements of the renal pelvis before and after voiding is useful for identifying children who are suspected to have VUR and thus require immediate VCUG.
