RESUMEN
Hemophagocytic lymphohistiocytosis (HLH) is a rare, albeit potentially fatal, condition in which fever, hepatosplenomegaly, and cytopenia predominate the clinical picture. Although it may be primary, it may also develop secondary to various etiologies. Herein, we aimed to report a patient who was diagnosed with pulmonary tuberculosis, developed fever and cytopenia during follow-up, and received immunomodulatory therapy together with antituberculosis therapy for the diagnosis of HLH. Sequencing of PRF1 showed heterozygous mutation. Although primary HLH has been detected in infants and children, genetic mutation of genes should be considered a differential diagnosis of HLH even in the adolescent.

RESUMEN
Although various modalities are currently in use to define pediatric aortic arch hypoplasia (AAH), there is little uniformity among them. We aimed to determine the inter-rater strength of agreement of the nomograms in a survey of patients less than 1 year old, who had undergone coarctation of the aorta (CoA) repair with or without AAH. This retrospectively designed study comprised of 105 patients with CoA, who had been evaluated between 2008 and 2018 by means of a computed tomography angiogram. Through re-estimation of the aortic arch segmental diameters, the z scores were calculated using three nomograms (Cantinotti, Pettersen, Lopez). Along with a t test and Pearson's correlation coefficient, a linear regression analysis, Bland-Altman plots, and Cohen's kappa k value were used to evaluate inter-rater strength of agreement. The mean age and weight of the cohort was 73.3 ± 81.2 days and 4.2 ± 1.6 kg, respectively. Sixty-four (61%) patients were neonates. The z scores of the nomograms for each aortic arch segment were significantly different. Although there was a significantly positive correlation between the nomograms with their related aortic arch diameter, the differences in z scores revealed considerable deviations in the scatter plot diagrams. The mean difference of z scores was significantly different from the testing value of zero, which was also presented in Bland-Altman plots. None of the comparisons reached a kappa k value of > 0.9. The current nomograms do not reveal an acceptable level of agreement for the definition of the AAH. The question is which modality to rely on when deciding on the surgical approach and technique of CoA repair to address the hypoplastic aortic arch segment. Decisions about the surgical approach and the technique of repair warrant a reliable definition of AAH. It is high time that a consensus is reached in this regard.

Adrenocortical tumor (ACT) is a rare malignant tumor which usually present with Cushing syndrome and virilization. Paraneoplastic syndromes (PNS) due to neoplasms can occur with peptides or cytokines secreted by the tumor. Here, we report a 13-month-old-male presented with severe masculinization. He had signs of precocious puberty with enlarged testicles, very high testosterone levels but low levels of gonadotrophins, and elevated ß-hCG. He underwent a left nephrectomy. The histopathological evaluation revealed a diagnosis of adrenocortical neoplasm. The levels of androgens and ß-hCG normalized after the resection of tumor, and the clinical findings improved within few months. We report the first pediatric patient with peripheral precocious puberty due to an ACT that secretes ß-hCG as PNS. A ß-hCG secreting ACT can cause severe virilization due to increased gonadal androgens stimulated by ß-hCG as well as due to increased adrenal androgens from the tumor.

Takayasu's arteritis (TA) is a rare chronic granulomatous vasculitis characterized by large-vessel involvement. The aorta and its main branches are most commonly involved. Although pulmonary artery involvement is common, hemoptysis or respiratory findings are rarely seen. Herein, we present a case of TA who developed anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis with diffuse alveolar hemorrhage after coronavirus disease 2019 (COVID-19) infection. A 17-year-old female patient with the diagnosis of TA presented with cough, bloody vomiting, and diarrhea. In follow-up, she developed tachypnea and dyspnea and was transferred to the pediatric intensive care unit. The findings on the chest computed tomography were compatible with acute COVID-19 infection, but the SARS-CoV2 reverse transcription-polymerase chain reaction test was negative, but SARS-CoV2 immunoglobulin (Ig) G and IgM antibody tests were positive. The patient was not vaccinated against COVID-19. The bronchoscopy showed bronchial mucosal fragility, bleeding foci, and mucosal bleeding. The broncoalveolar lavage hemosiderin-laden macrophages were seen in the histopathologic examination. The indirect immunofluorescence assay-ANCA test became 3 (+) with myeloperoxidase (MPO)-ANCA of 125 RU/ml (normal: <20). Cyclophosphamide and pulse steroid treatment were started. After immunosuppressive therapy, the patient condition improved and did not have hemoptysis again. The successful response was obtained by applying balloon angioplasty to the patient with bilateral renal artery stenosis. Types of post-COVID vasculitis include thromboembolic events, cutaneous vasculitis, Kawasaki-like vasculitis, myopericarditis, and ANCA-associated vasculitis. It is thought that COVID-19 may impair immune tolerance and trigger autoimmunity with cross-reaction. To the best of our knowledge, the third pediatric case was reported with MPO-ANCA-positive COVID-associated ANCA vasculitis.
RESUMEN
Hematologic disorders and malignancies are commonly encountered in children. The central nervous system is affected by many benign and malignant hematological diseases. Neurologic findings may occur due to central involvement of hematological disease or neurotoxic effects of treatment during the disease. At all these stages, radiological imaging and evaluation have a critical role. In this review article, we aim to describe the imaging findings of central nervous system involvement in pediatric hematologic diseases. This review was prepared based on the latest literature available in the PubMed database in the English language from inception to March 2022. The radiological images of the patients in our archive were obtained from the PACS (Picture Archiving and Communication Systems) to set an example for the diseases described in the text.
RESUMEN
OBJECTIVE: To retrospectively evaluate the imaging and clinical findings of patients diagnosed with multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19. METHODS: The clinical, laboratory and radiological data of 110 patients (74 male and 36 female) diagnosed with COVID-19-related MIS-C between June 2020 and November 2021 were evaluated retrospectively. Cases with a diagnosis of MIS-C based on a positive real time polymerase chain reaction (RT-PCR) test or serology results according to the WHO criteria were included in the study. All the radiological data were evaluated by a pediatric radiologist with 14 years of radiology experience. RESULTS: Peribronchial thickening and hyperinflation were the most common findings on chest X-ray, while atelectasis and pleural effusion were often present in thoracic CT. Cardiac involvement was detected in 30% of the patients, mainly with valve insufficiency and systolic dysfunction, and 7.2% of these patients had sequalae findings. The most common abdominal findings were hepatosplenomegaly, mesenteric inflammation, lymphadenomegaly, thickening of the intestinal walls and free fluid. 23 of the patients had comorbidities. Neurological radiological findings observed in a total of six patients were reversible splenial lesion syndrome, posterior reversible encephalopathy syndrome, meningitis, and cerebral edema. 37 patients were followed up in the intensive care unit and 2 of them died. CONCLUSION: Radiological findings seen in MIS-C vary according to the affected system. There is no specific radiologic finding for this disease, but radiological findings can assist in the evaluation of affected systems and guide treatment. ADVANCES IN KNOWLEDGE: Since there are few studies with a limited number of patients in the literature, data on this subject are limited. We aimed to contribute to the literature with our large patient data.

Objective: Sacroiliitis (SI), an inflammatory arthropathy, may accompany pediatric inflammatory bowel diseases (IBDs), present with non- specific back pain, hence might be unnoticed. The aims of this study were to assess the frequency of the SI in children with IBD and determine the characteristics of the association of SI with the clinical hallmarks of the IBD. Methods: In this prospective, cross sectional study, twenty-seven children with IBD, 7-18 years of age were evaluated. Patients with low back pain or stiffness, alternating buttock pain, or hip pain were examined for the presence of SI. The radiologic manifestations on X-ray suggesting sacroilitis were confirmed with Magnetic resonance imaging (MRI). Results: Twenty-seven children (16 girls, female/male=1.45), with mean age of 12.55±3.6 years, of which 52% had ulcerative colitis (UC), 41% had Crohn's disease (CD), and two had indeterminate colitis (IC). The median time from IBD diagnosis was 6.0 (18.0) months for patients with SI and 12.0 (13.5) months for patients without SI. Low back pain or stiffness was observed in 13 patients (48%). SI was present in eight (30%) of the children with IBD. The patients with CD were more prone to SI (45% of CD vs. 21% of UC patients). All patients with SI were negative for HLA-B27 genotyping. The disease activity and gender were not associated with increased risk for SI. MRI was remarkable for bone marrow edema in all of the patient, followed by erosions in six of them (75%), synovial enhancement observed in five (63%), and erosion associated enthesitis of the pelvic region was observed in two (25%) of the patients. Conclusion: SI may remain obscured in children with IBD. Children with CD are more prone to SI than those with UC. Pediatric rheumatology-pediatric gastroenterology collaboration might augment screening in at-risk patients.
RESUMEN
Immunoglobulin G4-related disease (IgG4-RD) is an inflammatory disease characterized by a tumor-like infiltration of IgG4 positive plasma cells and fibrosis in various organs. The exact pathogenesis remains unknown. In this article, we discuss the diagnostic management of IgG4-RD with reference to clinical, serologic, pathological and radiological data on a 17-year-old male patient with lumbar vertebral involvement.
RESUMEN
OBJECTIVE: The objective of the study was to describe the findings of pediatric patients diagnosed with COVID-19 in computed tomography (CT) and chest X-ray (CXR) images. Therefore, the aim of this study is to show protecting the children from radiation as much as possible while guiding the diagnosis. METHODS: Between March and June 2020, 148 pediatric patients examined who underwent CT due to suspicion of COVID-19. Fifty patients of 148 with normal thorax CT and negative reverse transcription polymerase chain reaction (RT-PCR) were excluded from the study. Of the remaining 98 patients were evaluated retrospectively by two pediatric radiologists with 15 years of experience. RESULTS: The demographic, clinical, and laboratory data were evaluated for 52 RT-PCR-positive patients. CT finding of 23 RT-PCR positive and 12 negative patients was classified. According to our study, unilateral (61-67%), multifocal (50-52%), and peripheral (83-91%) involvement were higher in all groups. Lower lobe involvement was frequently detected (58-65%). The most frequently detected parenchymal lesion was ground-glass opacity followed by consolidated areas accompanying ground-grass opacities. Halo sign and vascular enlargement signs were the common signs of lung lesions (35%). In addition, some rare findings not previously described in this disease in children were mentioned in this study. The clinical course of all our patients was mild and control radiological imaging checked by CXR. CONCLUSION: Most pediatric patients have a mild course. Hence, a balance between the risk of radiation and necessity for chest CT is very important. Low-dose CT scan is more suitable for pediatric patients but still it should be used cautiously.
RESUMEN
Subcutaneous cervicofacial emphysema is a rare and life-threatening condition that results from various causes. In this report, we documented a case of a patient with severe subcutaneous cervicofacial emphysema a condition that falls under the umbrella of Munchausen's syndrome and discussed the workup of this patient. Thorough diagnostic investigations seeking the etiology of the condition proved unsuccessful. When faced with cases of recurring subcutaneous cervicofacial emphysema, where the root cause remains ambiguous a diagnosis of Munchausen's Syndrome should be considered.
RESUMEN
OBJECTIVES: In this study, we present our clinical severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) experience in patients with childhood rheumatic disease during novel coronavirus-2019 (COVID-19) pandemic. PATIENTS AND METHODS: A total of 87 patients (50 males, 37 females; median age: 12 years; range, 6.6 to 16 years) suspected of having COVID-19 at our pediatric rheumatology clinic between March 11th and October 15th 2020 were retrospectively analyzed. Demographic and clinical features, treatments, laboratory results, imaging findings, and clinical outcomes of the patients diagnosed with COVID-19 and/or multisystem inflammatory syndrome in children (MIS-C) were retrieved from the medical records. The diagnosis of SARS-CoV-2 infection was made based on the reverse transcriptase-polymerase chain reaction test. RESULTS: The most common rheumatic diseases were juvenile idiopathic arthritis and familial Mediterranean fever (35.6% and 34.5%, respectively). Twenty-six of these patients were treated with biological disease-modifying anti-rheumatic drugs. SARS-CoV-2 infection was tested as positive in 84 (96.5%) patients. Also, 51 (58.6%) patients had an epidemiological contact to a person with COVID-19. Eighteen patients met the clinical criteria and diagnosed with MIS-C. The COVID-19 outbreak also caused exacerbation of systemic disease in 56 children due to medication cessation, postponed drug switch, or recurrent viral infection. CONCLUSION: Children with rheumatic disease do not appear to present a higher risk of severe COVID-19. The immunosuppressive treatments can be adjusted in case of infection; otherwise, it is not recommended to interrupt the treatments. Physicians should be cautious about the hyperinflammatory syndrome associated with COVID-19 in rheumatic children, which may be severe in this group of patients and may be confused with primary diseases.
RESUMEN
OBJECTIVES: Cytotoxic lesions of the corpus callosum (CLOCCs) are secondary lesions associated with entities like infection manifested by restricted diffusion on diffusion-weighted cranial magnetic resonance imaging. Our objectives are to evaluate the clinic-radiological spectrum of pediatric patients with cytotoxic lesions of the corpus callosum (CC). METHODS: Children (0-18 years) admitted between February 2017 and May 2020 with splenial lesions showing diffusion restriction on MRI, either isolated or within involvement of other parts of the brain, were included retrospectively. The primary lesions of the CC (e.g. acute disseminated encephalomyelitis, acute ischemic infarction, and glioblastoma multiforme) were excluded. CLOCCs were divided into infection-associated, metabolic disorder-associated, and trauma-associated lesions, as well as CLOCCs involving other entities. Data were collected from the medical databases. RESULTS: Forty-one patients were determined to have CLOCCs. Twenty-five (61%) were infection-associated, nine (22%) were trauma-associated, and three (7%) were metabolic disorder-associated cases, including 2 inherited disorders of metabolism. There were four (10%) patients with other entities, three with epilepsy, and one had an apparent life-threatening event. Six patients had a known etiology among the infection-associated group; one had multisystem inflammatory syndrome caused by COVID-19 and one had been infected by COVID-19 without any complications. All the infection-associated patients with isolated splenial lesions recovered totally, although six patients required intensive care hospitalization. Four trauma-associated patients had sequela lesions. CONCLUSIONS: CLOCCs are associated with a spectrum of diseases, including the new coronavirus, COVID-19 infection. Infection-associated CLOCCs has the best prognosis, although severe cases may occur. Sequelae are possible based on the etiology.

Lipoma arborescens (LA) is a chronic, slowly progressive intra-articular lesion characterized by villous lipomatous proliferation of the synovium. Most cases have been described in elderly patients with degenerative or post-traumatic joint disease, but in several case reports, it has been considered to be related to inflammatory joint diseases. Here, we report a case of 17 years old female firstly presenting with bilateral swelling in both knees of five years duration, followed by the development of wide spread lipoma arborescens associated with the uncontrolled treatment of juvenile idiopathic arthritis.
RESUMEN
INTRODUCTION: Bronchiolitis obliterans (BO) is mainly caused by infections and hematopoietic stem cell transplantation (HSCT). This study aimed to investigate the health-related quality of life (HRQOL) of children with BO compared to the healthy children and also to assess the HRQOL according to the etiology. METHODS: Postinfectious (group 1) and post-HSCT BO (group 2) patients and healthy children were included in the study. HRQOL was assessed by the Short Form-36 (SF-36) and St George's Respiratory Questionnaire (SGRQ). Correlations between demographic and clinical characteristics, pulmonary function tests, high-resolution chest tomography scores, and HRQOL were assessed. RESULTS: Thirty-seven postinfectious and post-HSCT BO patients and 34 healthy children were included in the study. Mean age was 13.8 ± 0.7 years. Mean forced vital capacity and forced expiratory volume1 were 60.7 ± 2.7% predicted, and 49.8 ± 3.1% predicted, respectively. The SF-36 scores were lower in BO patients compared to healthy children (P < .01). Patients with better lung functions had higher SF-36 scores, but lower SGRQ. The number of inhaled therapies, acute exacerbations, hospitalizations were inversely correlated with SF-36. A positive correlation was found between these parameters and total SGRQ scores (r = .507, P = .02; r = .409, P = .12; r = .326, P = .049, respectively). SF-36 scores were better in group 1 for subscales of physical role functioning and social role functioning compared to group 2. (P = .01, P = .01, respectively). CONCLUSION: The HRQOL of patients with BO measured by SF-36 was low compared to healthy children. SF-36 scores were more affected in post-HSCT BO patients. HRQOL of children with chronic lung disease should be taken into consideration in the management of these patients.

Respiratory syncytial virus (RSV) is one of the most common causes of acute respiratory tract infections among children. 1%-2% of RSV infections require hospitalization. In addition to the respiratory system, cardiovascular system may be also affected by the RSV infection. A 7-year-old, previously healthy, female patient presenting with respiratory difficulties was admitted to the paediatric intensive care unit. The patient was intubated and connected to a mechanical ventilator because of acute respiratory failure. Her tracheal aspirate was studied for viral multiplex polymerase chain reaction (PCR), and RSV positivity was detected. Her echocardiogram revealed left ventricular dysfunction. She was put on fluid restriction, intravenous furosemide, and inotropic support. Her cranial magnetic resonance examination showed the signs of acute haemorrhagic encephalopathy. She underwent five sessions of therapeutic plasma exchange with fresh frozen plasma. She was extubated on the 18th day of admission and provided with respiratory support with high-flow oxygen therapy thereafter. On the 23rd day, when her clinical status remained stable, she was transferred to the paediatrics ward. An RSV infection should be considered in cases with acute necrotising encephalitis and myocarditis.
RESUMEN
Background Diabetes and hepatosteatosis are dramatically increasing in childhood. Non-alcoholic fatty liver disease (NAFLD) is defined as a common disorder in adulthood, especially with type-2 diabetes and metabolic syndrome, while very few studies are available on liver health in children with type-1 diabetes. Patients and methods One hundred and ten (52 males and 58 females) patients with type-1 diabetes aged between 8 and 18 years were examined. The lipid profile, liver enzymes and hepatobiliary ultrasound findings of patients were investigated in terms of hepatopathies. Patients diagnosed with fatty liver were evaluated by pediatric gastroenterology specialists for the differential diagnosis and exclusion of other etiologies. The relationships between hepatopathy and age, pubertal status, the duration of diabetes and glycemic control were evaluated. Results Hepatopathy was found in 17 (15.5%) patients. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were normal and did not correlate with the ultrasonography (USG) findings. Hyperechogenicity detected by USG, whether it is true fat or glycogen hepatopathy, was found to be associated with "poor glycemic control" independently of age, puberty status and the duration of diabetes. Conclusions This study contributes to the literature in terms of the relationship between liver health and glycemic control in pediatric type-1 diabetes. Hepatopathies were releated with poor glycemic control independently of the duration of diabetes. This suggested that liver disorders should be considered as one of the subacute complications of diabetes. It was concluded that routine screening for comorbidities and complications in type-1 diabetes should also include hepatobiliary USG, as liver enzymes alone are inadequate for detecting hepatopathies.

Generalized arterial calcification of infancy (GACI) is a rare autosomal-recessive disorder, characterized by calcification of the internal elastic lamina, fibrotic myointimal proliferation of muscular arteries and resultant arterial stenosis. Treatment with bisphosphonates has been proposed as a means of reducing arterial calcifications in GACI patients, although there is no formalized treatment approach. The case reported here was a patient with severe GACI diagnosed at three months of age who had no response to bisphosphonate treatment, but clinically improved after the initiation of magnesium and anti-phosphate (using calcium carbonate) treatments. In patients unresponsive to bisphosphonate, magnesium and anti-phosphate treatment may be attempted.
