The role of cumulative risk and armed conflict exposure in adolescent psychological symptoms in Turkey.

Exposure to risk factors and adversity may cause immediate, and sometimes prolonged, psychological symptoms in adolescents. Identifying universal and specific risk factors in a particular context and examining their cumulative effects is crucial for understanding the mechanisms underlying psychological symptoms and informing about strategies for intervention. Using concurrent measures, the current study aimed to examine the role of armed conflict experiences and cumulation of other risk factors (e.g., maternal psychological symptoms, socioeconomic indicators) in predicting adolescent psychological symptoms in an underresearched community. The sample included 161 adolescents (54.7% female) aged 11-14 years (M = 12.36, SD = 1.27) and their mothers living in the east of Turkey. The cumulative risk index was calculated by summing the standardized scores of the corresponding factors. Hierarchical multiple regression analyses were conducted to predict internalizing and externalizing symptoms among adolescents by introducing demographic variables (age, gender) in the first step, armed conflict experiences and cumulative risk in the second step, and their interaction in the final step. Results showed that the levels of internalizing and externalizing symptoms were predicted by gender, armed conflict experience and cumulative risk. Being a girl was associated with higher levels of internalizing symptoms and lower levels of externalizing symptoms. Higher levels of internalizing and externalizing symptoms were predicted by exposure to armed and cumulative risk. After controlling for other factors, the interaction of armed conflict experience and cumulative risk significantly predicted externalizing, but not internalizing symptoms. These findings suggested that cumulative risk was a stronger predictor of psychological symptoms, and further amplified the strength of the association between armed conflict experiences and externalizing symptoms. These findings can be used in the formulation of intervention strategies and policies to promote psychological well-being in adolescents living in armed conflict zones under multiple risks.

The Role of Socioeconomic Adversity and Armed Conflict in Executive Function, Theory of Mind and Empathy in Children.

This study investigates the role of socioeconomic adversity and armed conflict in executive function (EF), theory of mind (ToM) and empathy in a rarely studied group, children living in eastern Turkey. The data were collected from 115 children (60 girls) aged 39 to 95 months (M = 68.22, SD = 14.62). Results revealed that children's performance was low in the EF and ToM tasks, and high in the empathy task. In path analysis, controlling for age, armed conflict experience predicted lower EF (ß = - 0.15) and higher empathy (ß = 0.21), and socioeconomic adversity predicted lower ToM (ß = 0.20). These findings contribute to our knowledge on cognitive and emotional development of children who live in such disadvantaged contexts.

Cerebral developmental venous anomalies in children with mismatch repair deficiency.

BACKGROUND: Constitutional mismatch repair deficiency (CMMRD) is one of the rare cancer predisposition syndromes. The aim of this study was to evaluate the cerebral developmental venous anomalies in children with central nervous system tumors associated with CMMRD, an area in which there is extremely little experience. METHODS: Data from children diagnosed with medulloblastoma and high grade central nervous sytem tumor were retrospectively collected. According to the European CMMRD criteria, nine patients were diagnosed as CMMRD syndrome and the others consisted of the group without CMMRD. All radiological examinations of these children were retrospectively reviewed. Whole exome sequencing was performed to index cases` germline DNA. RESULTS: Nine children from four families, six females and three males, were studied. The median age at the first tumor diagnosis was 4.5 years (range, 9 months to 14 years). All CMMRD patients had café au lait spots, but none fulfilled the diagnostic criteria for neurofibromatosis. The patients developed high-grade glial tumor (n: 7) and medulloblastoma (n: 2). The affected genes in the three families were MSH6 [c.478C > T (p.Gln160Ter)], MSH6 [c.2871dupC (p.Phe958LeufsTer5)] and MLH1 [c.236G > A(p.Arg79Lys)], respectively. Seven patients had multiple developmental venous anomalies; six patients had leptomeningeal enhancement; and five patients had cavernomas. None of these findings were present in the group without CMMRD. CONCLUSIONS: Constitutional mismatch repair deficiency should be considered when multiple developmental venous anomalies, cavernomas, and leptomeningeal enhancement are detected, especially in patients with café au lait spots.

Familial clustering of nasopharyngeal carcinoma in the family of an adolescent with nasopharyngeal carcinoma.

BACKGROUND: Nasopharyngeal carcinoma (NPC) is one of the rare malignant diseases of childhood, of which only 1% occurs in children. In recent years, genetic factors have attracted attention in NPC. A very limited data have been reported about clustering within families. CASE: Herein, the familial clustering of nasopharyngeal carcinoma in the family of an adolescent with nasopharyngeal carcinoma is presented. CONCLUSIONS: There is familial clustering in nasopharyngeal carcinoma (NPC), but our knowledge on this subject is limited, especially in children or adolescent populations. Therefore, we should be more careful in NPC in childhood, especially in first-degree relatives.

A pediatric bithalamic high grade glioma with concomitant H3K27M and EGFR mutations.

BACKGROUND: Despite many treatment approaches, survival rates in high grade glial tumors are still not at the desired level. One of the cause of this failure might be that although having similar histologic features, they may display different biological behaviors depending on molecular heterogeneity. CASE: A 10-year-old girl presented with sudden onset left sided hemiparesis, headache, and ataxia. Physical examination was normal except for left sided hemiparesis and ataxia. A hyperintense mass lesion involving the bilateral thalamus was detected in the axial T2-weighted and coronal FLAIR sequences on brain MRI. There was no enhancement in axial T1-weighted contrast-enhanced sequences. Due to the size and location of the tumor, the patient was considered inoperable. Intensity modulated radiotherapy was intended for curative treatment to the patient because the radiological findings suggested a low-grade glial tumor. Tumor was unresponsive to radiotherapy but biopsy could be performed. The histopathological examination revealed a diffuse glial tumor with increased cellularity, mild nuclear atypia and rare mitosis. Due to the infiltrative pattern of the tumor, it was accepted as a high grade diffuse glial tumor. A chemotherapy protocol including cisplatin and etoposide in the first cycle, vincristine and cyclophosphamide in the second cycle, and carboplatin and vincristine in the third cycle were instituted to the patient. After the third cycle of chemotherapy, the tumor progressed radiologically. H3.1 K27M c.83A > T (HIST1H3C p.Lys28Met), ATRX c.2169_2170del (p.Glu723AspfsTer9), TP53 c.338T > C (p.Phe113Ser), and EGFR c.2300_2308dup (p.Ala767_va1769dup) were detected in the genetic assessment of tumor tissue. The patient`s treatment was changed to vincristine, temozolomide, and irinotecan. Unfortunately, MRI showed progression after three cycles of second-line chemotherapy. The patient`s family refused any further treatment, and the patient died with progressive disease in a short time. CONCLUSIONS: EGFR mutation along with H3.1 K27M mutation is extremely rare in children to our knowledge. It should be kept in mind that if there is a possibility of targeted therapy, there may be a treatment option in this malignant disease with a poor prognosis.

Impact on the survival of neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and monocyte-lymphocyte ratio on prognosis in children with Hodgkin lymphoma.

OBJECTIVES: To evaluate the clinical utility of the recently described absolute neutrophil counts to absolute lymphocyte counts ratio (NLR), absolute platelet counts to absolute lymphocyte counts ratio (PLR), and absolute monocyte counts to absolute lymphocyte counts ratio (MLR) on prognosis in children with Hodgkin lymphoma (HL). METHODS: We retrospectively evaluated the clinical characteristics, laboratory features (lymphocyte counts, NLR, PLR, and MLR), treatment, and results of 52 children with HL in the Department of Pediatric Hematology and Oncology, Selcuk University, konya, Turkey, from January 2006 until December 2021. RESULTS: The patients included 27 (51.9%) females and 25 (48.1%) males. The age of the patients ranged between 3-17.5 years old (median: 9 years). There were 22 patients in stage II, 24 in stage III, and 6 in stage IV. The most prevalent histopathological subgroup was the nodular sclerosing type (53.8%). The 5-year overall survival rate was 93.7%. The overall survival rate differed based on lymphocyte counts (p<0.0001), NLR (p=0.018), and PLR (p=0.009). However, none of the prognostic factors in the univariate analysis were not prognostic risk factors (p>0.05) in the multivariate analysis. CONCLUSION: Lymphocyte counts, NLR, and PLR may be useful markers for determining the outcomes in children with HL.

Clinical Utility of Total Oxidative Stress and Total Antioxidant Capacity in Childhood Febrile Neutropenia.

The aim is to determine the oxidative status of children with febrile neutropenia (FEN). Blood samples were collected to determine the total antioxidant capacity (TAC) and total oxidative status (TOS) of healthy children (once) and children with FEN after 0, 48, and 96 hours. Eighteen patients with FEN were evaluated. The baseline TAC level of patients was significantly higher than that of the controls (P<0.0001). The TAC levels of patients with FEN with and without antibiotic modification were higher than those of the controls (P=0.002 and 0.02, respectively). The TAC levels of the patients with FEN with antibiotic modification were lower than those of the patients without antibiotic modification (P=0.0224). The oxidative stress index (OSI), calculated TOS/TAS, value of the children with FEN was lower than that of the controls (P<0.0001). The OSI values of the patients with FEN with and without antibiotic modification were lower than those of the control group (P=0.001 and <0.0001, respectively). The TAC values of the patients with antibiotic modification were higher than those of the patients without antibiotic modification (P=0.02). In conclusion, the oxidative status of the children with FEN was affected, and it can give information about the follow-up of FEN.

Clinical Features, Treatment and Outcome of Childhood Glial Tumors.

AIM: To evaluate the clinical features, treatment approaches, and outcomes of glial tumors in children. MATERIAL AND METHODS: Files (2006 to 2020) of children diagnosed with glial tumors and followed-up were reviewed retrospectively. Information regarding demographic and clinical characteristics, treatment approaches, and outcomes were retrieved from the patients? files. RESULTS: Of the total of 180 pediatric patients diagnosed with brain tumors, 73 (40.6%) had glial tumors. The children with astrocytoma were in the age range of 2?18 years (median age: 8.7 years), while the ages of children with ependymoma ranged from three months to 10 years (median age: 3 years). This difference was statistically significant (p < 0.0001). The male to female ratio was 1.6. The most common symptoms or signs were headaches (n=34, 46.6%), abnormal gait or coordination (n=22, 30.2%), vomiting (n=21, 28.8%), and cranial nerve palsies (n=20, 27.4%). The pathological diagnoses were astrocytomas (n=53, 72.6%), oligodendroglial tumors (n=2, 2.7%), ependymoma (n=15, 20.7%), and other glial tumors (n=3, 4.1%). The most common tumor location was supratentorial (n=42, 57.5%), while midline glioma was detected in seven patients. The 5-year overall survival (OS) rate of all glial tumors, astrocytoma, and ependymoma was 42%, 40%, and 55%, respectively. The 5-year OS rate of the tumor Grade I, II, III, and IV was 77.2%, 45%, 32%, and 0%, respectively (p < 0.0001). The 5-year OS rate of supratentorial, infratentorial, and spinal tumors was 25.6%, 63.6%, and 50%, respectively (p=0.021). In Cox regression analysis, it was found that the tumor resection and grade had an effect on the tumor prognosis. CONCLUSION: Treatment results are not satisfactory in high-grade astrocytomas. There is a need for new treatment approaches that would take cognizance of molecular features and adopt multidisciplinary approaches.

Effect of Exenatide Use on Cognitive and Affective Functioning in Obese Patients With Type 2 Diabetes Mellitus: Exenatide Use Mediates Depressive Scores Through Increased Perceived Stress Levels.

PURPOSE/BACKGROUND: Glucagon-like peptide-1 (GLP-1) is a molecule used to treat type 2 diabetes mellitus (T2DM). Given their widespread expression in the nervous system, GLP-1 receptors also play a role in regulating mood and cognitive function. Here, we aimed to compare obese patients with T2DM, with or without exenatide (a GLP-1R agonist) use on cognitive and affective functioning. METHODS/PROCEDURES: A total of 43 patients with T2DM (23 on exenatide and 20 without exenatide) were evaluated with the Snaith-Hamilton Pleasure Scale, Cognitive Failures Questionnaire, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7, Childhood Trauma Questionnaire, Perceived Stress Scale (PSS), and Chronic Stress Scale, in addition to laboratory-based measures of reward learning (the probabilistic reward task) and working memory (Letter-N-Back task). FINDINGS/RESULTS: Patients on exenatide had higher body mass index (BMI) (37.88 ± 5.44 vs 35.29 ± 6.30; P = 0.015), PHQ-9 (9.70 ± 4.92 vs 6.70 ± 4.66; P = 0.026), and PSS (29.39 ± 6.70 vs 23.35 ± 7.69; P = 0.015) scores. Other stress scales (Childhood Trauma Questionnaire and Chronic Stress Scale), Generalized Anxiety Disorder-7 scores, response bias, or discriminability as assessed by probabilistic reward task and self-report (Cognitive Failures Questionnaire) and laboratory-based (Letter-N-Back) cognitive measures were not significantly different between groups (both Ps > 0.05). Multivariate linear regression analyses adding BMI and PSS as covariates revealed that although BMI had no effect (P = 0.5), PSS significantly predicted PHQ-9 scores (P = 0.004). Mediation analysis showed that exenatide users reported higher PSS, with greater PSS associated with higher PHQ-9 levels (b = 0.236). There was no evidence on exenatide directly influencing PHQ-9 independent of PSS (c' = 1.573; P = 0.305; 95% bootstrap confidence interval, -1.487 to 4.634). IMPLICATIONS/CONCLUSIONS: Based on previous research and our findings, exenatide use might be mediating depression scores through disrupting stress responses.

Nasopharyngeal carcinoma in a child with Kartagener`s syndrome.

BACKGROUND: Kartagener`s syndrome, a subgroup of primary ciliary dyskinesia, is characterized by situs inversus totalis, chronic sinusitis and bronchiectasis. To date, the association of malignant diseases and Kartagener`s syndrome has been reported and all cases except angioimmunoblastic T cell lymphoma in a child have been seen in adulthood. CASE: A 10-year-old boy who was followed with the diagnosis of Katagener`s syndrome, presented with a progressive mass in the cervical region for 6 months. Physical examination revealed mental retardation, multiple lymphadenopathies, the largest in the left cervical region (4x4 cm), and pectus carinatum. Also, on cardiovascular examination, apex beat was felt on the right fifth intercostal space along midclavicular line. Magnetic resonance imaging of nasopharynx showed narrowing of the nasopharyngeal airway with an increase in wall thickness up to 2.5 cm on the posterior wall of the nasopharynx. Also, bilateral multiple cervical lymphadenopathies were noted. The pathological examination of the biopsy from cervical lymphadenopathy revealed a diagnosis of undifferentiated nasopharyngeal carcinoma. Chemotherapy was started for nasopharyngeal carcinoma chemotherapy regimen including cisplatin, docetaxel, and 5-fluorouracil. After four cycles of chemotherapy there was a significant regression in nasopharyngeal mass and lymphadenopathies. The patient underwent radiotherapy to the nasopharynx and bilaterally cervical regions. The patient has been in follow-up for 6 years well and tumor free. However, he is still under the supervision of the pediatric immunology and allergy departments due to recurrent respiratory infections and sinusitis. CONCLUSION: We present a case of nasopharyngeal carcinoma which developed in a child with Kartagener`s syndrome. To our knowledge, this is the first report of nasopharyngeal carcinoma in a child with Kartagener`s Syndrome.

A Prolonged Activated Partial Thromboplastin Time in a Child With Hodgkin Lymphoma.

A 3-year-old girl presented with fever and left-sided neck mass that did not resolve despite antibiotic treatment. Physical examination was normal except lymphadenopathy in the left cervical region. Complete blood count was Hb: 8.01 g/dL, leukocyte count: 4034/mm3, platelet count: 286,000/mm3. On preoperative period, coagulation studies revealed a prolonged activated partial thromboplastin time (aPTT, 46.1 s [N: 21 to 36]), corrected mixing test for aPTT. The prothrombin time and international normalized ratio were in normal limits. Factor VIII levels, von Willebrand factor antigen, and ristocetin cofactor were normal. After the patient was given fresh frozen plasma, lymph node excision was performed. As a result of pathologic examination, Hodgkin lymphoma was diagnosed as classic type. The patient was instituted ABVD chemotherapy protocol for Hodgkin lymphoma. The aPTT at the sixth day of treatment was within normal limits. Coagulation test abnormalities are extremely rare in Hodgkin lymphoma. To our knowledge, this is the first report of prolonged aPTT in a child with Hodgkin lymphoma.

Breast complaints in children and the effect of family history.

BACKGROUND: To evaluate the correlation of physical examination, and radiological and pathological findings of children and adolescents with breast-related complaints. METHODS: Children and adolescents with breast complaints between January 2016 and December 2019 were analyzed retrospectively. RESULTS: A total of 118 children and adolescent patients were included. Their ages ranged from 12 to 18 years (median, 16 years). Twenty-one patients had a family history of breast cancer (17.8%). The most common complaints were pain, mass, and nipple discharge. Physical examination revealed mass (41.5%), tenderness (11%), and fullness (8.5%). Thirty-nine patients were classified ultrasonographically with Breast Imaging Reporting and Data System (BIRADS) 3 (39.4%) and four patients were BIRADS 4 (4%). Excision was applied to all patients with BIRADS 4, and 13 of 39 patients with BIRADS 3. Pathological diagnoses of the patients with BIRADS 3 were fibroadenoma (n: 12, 92.3%) and benign phyllodes tumor (n: 1, 7.7%). In patients with BIRADS 4, three patients had fiboradenomas and one patient had a benign phyllodes tumor. No recurrence was observed in any patients who had an excision. Only six of the patients with positive family history had BIRADS 3 lesions, and the others were BIRADS 1. Excision was recommended in two patients and the pathological diagnoses were fibroadenoma. CONCLUSION: In this age group, the most common complaints were pain and mass, while physical examination was normal in nearly half of the patients. All of the pathological diagnoses were benign. While evaluating the patients in this age range, the experience of the clinician and radiologist is important and we think that it is necessary to increase the awareness of the patient and family about physiological breast development and self-breast examination.

Delayed Radiation Myelopathy in a Child With Hodgkin Lymphoma and ARTEMIS Mutation.

The authors present a case of delayed radiation myelopathy in a 12-year-old girl with Hodgkin lymphoma and Artemis mutation. This is the first of such a case presented in the literature.

Pseudoangiomatous Stromal Hyperplasia of Breast in an Adolescent: A Case Report and Review of the Literature.

BACKGROUND: Pseudoangiomatous stromal hyperplasia (PASH) is a rare benign breast lesion that is is extremely rare in children and adolescents. CASE: A 13-year-old girl was admitted to our clinic with a giant mass in the left breast for 3 months. Physical examination findings of the patient were normal except for the mass in the breast. The mass was removed totally, and its pathological diagnosis was pseudoangiomatous stromal hyperplasia. The patient has been followed up for 6 months without disease.

Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis in Children With Non-Hodgkin Lymphoma.

The aim of this study is to evaluate the clinical and laboratory findings of pediatric patients with non-Hodgkin lymphoma (NHL) who developed Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Between 2006 and 2018, the medical records of child patients with NHL who developed SJS and TEN were reviewed retrospectively. SJS/TEN developed in 7 of 70 patients with NHL (10%). The pathologic subgroups of the patients with SJS/TEN were ALK-negative anaplastic large cell lymphoma (n: 3), Burkitt lymphoma (n: 2), lymphoblastic lymphoma (n: 1), and primary mediastinal B-cell lymphoma (n: 1). Five patients had TEN, 1 patient had SJS/TEN, and 1 patient developed only SJS. In 5 patients, both steroids and intravenous immunoglobulin were administered for treatment, and clinical improvement was achieved in 3 of these patients. Only steroid treatment was used for 1 patient, whereas for the other patient, intravenous immunoglobin was preferred. In addition, N-acetylcysteine treatment was administered for these 2 patients. Four patients with acute renal failure died, and it was found that SJS/TEN is observed more frequently in patients with NHL in which intensive treatment protocols with high-dose methotrexate are used more than with other childhood malignant diseases. Early diagnosis and administration of appropriate and supportive treatment approaches may improve the prognosis.

Pediatric Lymphoma and Solid Tumors Associated With Cancer Susceptibility Syndromes.

The aim of this study was to determine cancer susceptibility syndromes (CSSs) in children with lymphoma and solid tumors and to evaluate their effects on overall survival rates. Between 2006 and 2019, the oncologic charts of 672 patients who were followed-up with a diagnosis of lymphoma and solid tumor in our clinic were retrospectively reviewed. CSSs were detected in 42 children (6.25%). The most common CSS was DNA damage repair defects/genetic instability (in 18 of 42 patients with CSSs, 42.8%). In the patients with CSSs, 48 different cancers developed. The most common types of cancer were lymphoma (n: 10, 21%) and high-grade glial tumor (n: 9, 19%). The lymphoma subgroups were very rare childhood lymphomas, such as gray zone lymphoma and marginal zone lymphoma. The overall survival rates for patients with DNA damage repair defects/genetic instability; with CSSs other than DNA damage repair defects/patients with genetic instability syndrome; and without any CSS, were 9.7%, 65.1%, and 68.7%, respectively. The overall survival rate for patients with DNA damage repair defects/patients with genetic instability syndrome was lower than both patients with CSSs other than DNA damage repair defects/genetic instability syndrome (P=0.002) and those without any CSS (P<0.0001). CSSs should be kept in mind in children with cafe au lait spots; syndromic features; a family history of cancer, especially in siblings; and rare childhood cancers.

Bounce Forward: A School-Based Prevention Programme for Building Resilience in a Socioeconomically Disadvantaged Context.

Socioeconomic status is a strong predictor of normative development and well-being in young people. It is well-known that growing up in a socioeconomically disadvantaged context may lead to negative outcomes, both in childhood and in adulthood. Early intervention and prevention programmes are crucial for building resilience and improving health, well-being and equity. Bounce Forward is a school-based prevention programme implemented in Blackpool, a town in the United Kingdom facing multiple challenges. It was part of a whole town resilience approach and nascent global social movement known as the "Resilience Revolution." Between 2017 and 2019, the programme was delivered in all Year 5 classes at every primary school in Blackpool (n school = 36), reaching out to 3,134 students (ages 9-10; 50.4% male). The programme aimed to increase resilience in young people by building knowledge and skills about mental health and resilience through 10 sessions. In the current study, we longitudinally examined a range of protective factors, which are relevant to young people's resilience, as well as their mental health outcomes at three time points: before they participated in Bounce Forward, at the end of the programme, and 3-5 months later, when they started Year 6. The current sample included 441 Year 5 students (54.2% male) from 11 primary schools in Blackpool. Nineteen teaching staff also participated in the study and provided qualitative data regarding the impact of the programme on their students. Results showed improvement in some areas of young people's resilience after taking part in Bounce Forward. We also identified gender differences in several protective factors, indicating that boys may need further support. Teaching staff highlighted improvements in various areas; and also observed that their students have been using the strategies that they learnt from the programme. Altogether, findings suggested that young people benefitted from Bounce Forward. The programme is sustainable, offering a free to download teacher resource pack that allows schools to self-deliver it.

Under poverty and conflict: Well-being of children living in the east of Turkey.

Children living in armed conflict zones are often exposed to political violence and other risk factors that may be caused or exacerbated by the conflict, such as poverty and family violence. If left untreated, these experiences may cause psychological problems throughout life. This study investigated the psychological well-being of children living in the low-intensity armed conflict zone in Turkey in relation to their adverse experiences. We collected data from 409 caregivers for their children (236 girls) aged 5.5 to 18 years (mean [M] = 11.50, standard deviation [SD] = 3.65). Caregivers provided information regarding their children's emotional and behavioral problems (internalizing, externalizing, and total problems; posttraumatic stress symptoms [PTSS]), income, family violence, and armed conflict experiences. Caregivers reported moderate levels of problems among children. The prevalence of borderline/clinical (T ≥ 60) scores was 14.3% for internalizing, 12.6% for externalizing, and 14% for total problems and 7.9% for PTSS. Notably, almost all families resided in extreme poverty. The prevalence of family violence was 36%. Children were frequently exposed to conflict-related events. Hierarchical regressions showed that after controlling for the role of demographic variables and other risk factors, income predicted total problem level (ß = -.10), and family violence (ßs = .17 to .26) and armed conflict (ßs = .13 to .20) experiences predicted internalizing, externalizing, and total problems and PTSS levels. Our findings suggest that family violence and armed conflict pose a significant risk to children's psychological well-being and inform intervention strategies and policy decisions to promote welfare in such disadvantaged contexts.
