RESUMEN
We report a case of a primary cardiac spindle cell neoplasm with concerning histological features and a rare PDGFRA::USP8 gene fusion in a 3 year old boy. The patient presented with a large cardiac mass predominantly in the right ventricle, originating from the ventricular septum. The mass was resected with grossly negative margins. Pathology revealed an unclassified spindle cell neoplasm with a PDGFRA::USP8 gene fusion. This gene fusion has only been previously reported twice in the medical literature, one in a pediatric cardiac sarcoma and the other in an abdominal soft tissue tumor in an adult woman. The patient is alive and well with no evidence of recurrence 11 months after excision.
RESUMEN
INTRODUCTION: In recent decades, serious changes have been observed in social gender roles. More and more publications have been published regarding the connection between masculinity and mental disorders. Most of the professional guidelines related to major depression have not been adapted yet to social changes in gender roles, or only to a small extent. OBJECTIVE: The authors of the article present the possible influence of masculinity on psychotherapies, focusing on clients suffering from major depressive disorder. METHOD: In our manuscript, we first summarize the psychosocial changes that affect the male gender role in Western societies. After that, we review the possible impact of this transformation on psychotherapies. We mainly deal with the relationship between the onset of major depressive disorder and the male gender role. At the end of our publication, we make recommendations on how to integrate our knowledge of masculinity into the context of therapy. RESULTS: Individual socialization differences related to the male gender role and social expectations can greatly influence the appearance of mental illnesses. Internalized and externalized symptoms should also be taken into account in the recognition and treatment of major depressive disorder. Positive masculinity as a therapeutic framework can be successfully combined with specific psychotherapies in order to personalize the healing process. CONCLUSIONS: In recent years, mental health care sensitive to gender roles has gained more and more space. Although we already have more and more information about how masculinization affects the clinical picture of mental illness, such as major depressive disorder, further studies are needed for more effective diagnosis and therapy.

BACKGROUND: Prenatal or postnatal lung inflammation and oxidative stress disrupt alveolo-vascular development leading to bronchopulmonary dysplasia (BPD) with and without pulmonary hypertension. L-citrulline (L-CIT), a nonessential amino acid, alleviates inflammatory and hyperoxic lung injury in preclinical models of BPD. L-CIT modulates signaling pathways mediating inflammation, oxidative stress, and mitochondrial biogenesis-processes operative in the development of BPD. We hypothesize that L-CIT will attenuate lipopolysaccharide (LPS)-induced inflammation and oxidative stress in our rat model of neonatal lung injury. METHODS: Newborn rats during the saccular stage of lung development were used to investigate the effect of L-CIT on LPS-induced lung histopathology and pathways involved in inflammatory, antioxidative processes, and mitochondrial biogenesis in lungs in vivo, and in primary culture of pulmonary artery smooth muscle cells, in vitro. RESULTS: L-CIT protected the newborn rat lung from LPS-induced: lung histopathology, ROS production, NFκB nuclear translocation, and upregulation of gene and protein expression of inflammatory cytokines (IL-1ß, IL-8, MCP-1α, and TNF-α). L-CIT maintained mitochondrial morphology, increased protein levels of PGC-1α, NRF1, and TFAM (transcription factors involved in mitochondrial biogenesis), and induced SIRT1, SIRT3, and superoxide dismutases protein expression. CONCLUSION: L-CIT may be efficacious in decreasing early lung inflammation and oxidative stress mitigating progression to BPD. IMPACT: The nonessential amino acid L-citrulline (L-CIT) mitigated lipopolysaccharide (LPS)-induced lung injury in the early stage of lung development in the newborn rat. This is the first study describing the effect of L-CIT on the signaling pathways operative in bronchopulmonary dysplasia (BPD) in a preclinical inflammatory model of newborn lung injury. If our findings translate to premature infants, L-CIT could decrease inflammation, oxidative stress and preserve mitochondrial health in the lung of premature infants at risk for BPD.

Background and purpose – Interdiscipli nary researches demonstrate that patients’ fears and anxieties about surgery play a key role in the success of postoperative recovery. Psychoeducation is a professional information transfer method that aims to increase patients’ knowledge about their dis ease, and how to cope with it, and to emo tionally process the problems associated with the disease. If patients feel competent in their own healing process after surgery, they will experience less pain and become selfsufficient sooner, thereby the number of nursing days spent in the clinic reduces.
Methods – In this study the effect of psycho-education before spinal surgery on the use of postoperative analgetics was investigated. Results – The drug consumption of the study group who had been previously administered patient education is significantly reduced in comparison the control group.
Conclusion – Cooperation of a psychologist in surgical therapy promotes early recovery of patients in physical and mental wellbeing and reduces the costs of rehabilitation as well.
RESUMEN
Progressive transformation of the germinal center (PTGC) is a common and underrecognized cause of pediatric lymphadenopathy. PTGC may be associated with numerous systemic medical conditions that require further workup and management, including malignancy, autoimmune conditions, lymphoproliferative conditions, immunodeficiency, and infection. Given the breadth and rarity of the associated conditions, workup should be tailored to the individual patient and occur in a tiered approach. Patients with PTGC require ongoing follow-up, given their long-term risk of malignancy and recurrent PTGC.

PURPOSE AND CONTEXT: Streptococcal Infection (SI) is an important cause of pediatric death in children, yet limited reports exist on autopsy findings in fatal SI cases. METHOD: Case records (1997-2019) of SI with no pre-existing risk factors were reviewed and selected. Their clinical and pathological findings in the autopsy reports were analyzed. RESULTS: In our cohort of 38 cases based on bacterial culture results, SI was most commonly caused by Streptococcus pneumoniae (SPn; 45%) and Streptococcus pyogenes (SPy; 37%). 92% of decedents had some prodromal symptoms prior to terminal presentation. The clinical course was often rapid, with 89% found unresponsive, suddenly collapsing, or dying within 24 hours of hospital admission. 64% of deaths were attributed to sepsis, more frequently diagnosed in the SPy group than in the SPn group (71% vs 48%). Pneumonia was found in both SPn and SPy groups, whereas meningitis was exclusively associated with SPn. CONCLUSION: Our study shows fatal SI is most commonly caused by either SPn or SPy, both of which are frequently associated with prodromal symptoms, rapid terminal clinical course, and evidence of sepsis. Postmortem diagnosis of sepsis is challenging and should be correlated with clinical features, bacterial culture results, and autopsy findings.

INTRODUCTION: The study is focusing on the relationships between several different, widely researched topics - such as satisfaction with relationship and life, well-being and the development of family structure - and examining them from different perspectives. In general, satisfaction with life, just as the subjective well-being displays high correlation with relationship satisfaction, which has effect on the development of the family structure as well. According to our assumption, those people who live in a happy and balanced relationship/marriage are happier and more satisfied with their lives. All of this is substantially influenced by one of the most important issues in people's lives/relationships, that is childbearing. This is also considerable for the development of life satisfaction and well-being. Moreover, a more balanced relationship is supposed to have a positive relationship with family cohesion, flexibility and communication within the family. METHOD: In the present study, we examined on our entire database the relationship between life satisfaction, well-being, relationship satisfaction and the possible changes in all of these relationships depending on the changes in the family structure. In our analysis, we also examined the effect of children's presence in the family in relation with relationship satisfaction. 192 people participated in the present study. RESULTS: According to the results, life satisfaction and the optimal communication within the family have a positive effect on relationship satisfaction. Satisfaction with family communication proved to be the strongest predictor. Despite our hypothesis, the number and age of children - more children and younger age - did not show a negative correlation with relatinship satisfaction. CONCLUSION: Not just during a crisis, under optimal circumstances, several factors affect relationship satisfaction, but the main influencing aspect is an optimal family structure. In a well-functioning family, the optimal level of communication has a positive effect on the development of the relationship, whereas disintegration and inadequate communication can lead to severe dysfunction both in terms of the relationship and the family unit. The results from the analysis show important conclusions and reveal new research directions, which should be examined in a larger sample in the future.

INTRODUCTION: Several studies have investigated the relationship between personality and psychoactive substance use. Researches of personality and marijuana use suggests that certain personality traits differentiate between occasional and regular marijuana consumers. Understanding the relationship between individual persona - lity traits and marijuana use is a key step in the development of prevention and treatment methods. In the current study, we present the development of emotion regulation difficulties, coping with stress, impulsivity, external-internal control and sensation seeking in occasional and regular marijuana users. METHODS: 322 people participated in our study, within this 51 occasional and 56 regular marijuana users and 215 non-marijuana users who formed the control group. The examined personality traits were measured with the Diffi - culties in Emotion Regulation Scale, the Coping Inventory for Stressful Situations, the Barratt Impulsiveness Scale, the Internal-External Locus of Control Scale and the Sensation Seeking Scale. RESULTS: Varying levels of marijuana use increased difficulty in emotion regulation as well as impulsivity. Addi tio nally, the use of emotion-oriented coping strategies were most common in occasional and regular marijuana use. Regular marijuana users were more likely to have external control than occasional users. Non-marijuana users were less sen - sation seekers that the two groups of marijuana users, however, we did not find significant difference between occasio nal and regular users.

BACKGROUND: Post-transplant malignancies, that is, lymphomas, are a recognized complication in intestinal transplant recipients but are mostly secondary to EBV infection. There is an increased risk for malignancies in unusual sites in intestinal transplant recipients as compared to other solid organ transplants and the general population. OBJECTIVE: To evaluate the incidence, course, and outcome of unusual malignancies in children after ITx. METHODS: Retrospective analysis of children who underwent ITx for primary digestive disorders at Birmingham Children's Hospital between January 1989 and December 2017. RESULTS: Ninety-eight intestinal transplants were performed in 90 children (49 males and 41 females) with an underlying primary digestive disorder. Median age was 2.7 years (0.6-16.2), and median weight was 14.5 kg (5.7-53.2) at the time of transplant. Within this cohort, we identified four cases of unusual malignancies at rare sites of presentation. One patient developed cerebral PTLD, two patients were diagnosed with SMT, located at the stomal orifice and in cervicothoracic paravertebral area, respectively, and the last patient developed a retroperitoneal angiosarcoma. Unfortunately, the overall patient outcome was poor in all but one child with SMT, who currently survives with cytotoxic T-cell therapy. CONCLUSION: Unusual malignancies can occur in approximately 5% of children following ITx. A high index of suspicion is required for a timely diagnosis and adequate treatment.

Cutaneous lymphadenoma is an uncommon benign neoplasm often considered to be an adamantinoid variant of trichoblastoma. Lesions present in both sexes, between 14 and 87 years of age, and are mainly located on the head and neck. Cases in children are rare and there is only 1 previous case of a congenital lymphadenoma. An 8-year-old Asian girl presented with a congenital lesion on her forehead comprising 4 pink papules, the largest 5 mm in diameter. Microscopy revealed a well-circumscribed tumor within the dermis and subcutis comprising well-demarcated epithelial lobules of basaloid and clear cells with subtle peripheral palisading, growing in a collagenous stroma but lacking retraction artefact. A relatively dense accompanying predominantly lymphocytic inflammatory cell infiltrate including both T-cells (CD3+) and B-cells (CD20+) permeated the nodules and spilled into the stroma. CD68+ histiocytes and CD1a+ Langerhans cells were moderately numerous. This is the second case of congenital lymphadenoma which-in spite of its rarity in childhood-widens the diagnostic possibilities of cutaneous lymphoepithelial tumors in children.

INTRODUCTION: The purpose of the study is to investigate dispositional procrastination, procrastination types, and an operative measurement of this behavior in academic environment. Procrastination is a common and problematic phenomenon that explains the need for a comprehensive and complex approach of this behavior. The main focus of the study was to investigate the incidence and incidence of the different types of procrastination. Furthermore, we aimed to test the correspondence between dispositional procrastination and the operative measurement. METHODS: The sample consisted of 131 participants. Lay's Procrastination Scale was used to measure dispositional procrastination and the Types of procrastination questionnaire was applied to assess the frequency of its different types. Furthermore an operative measurement was gained by assigning a deadline for returning the paper and pensil form of the questionnaire. Participants received a message informing them that the deadline had been extended by three more days on the last night before the deadline. RESULTS: Based on the empirical results 63% of the participants can be classified as procrastinator. In regards of the different types of procrastination, "perfectionist" and "crisis-maker" types were the most frequent. A positive correlation was found between dispositional procrastination and the operative measurement of procrastination. CONCLUSIONS: The results proved the common presence of procrastination, as well as the close connection between its dispositional and operative measure. Besides, they raise attention to the perfectionist and crisis-maker types of procrastination.

Patients with chronic rhinosinusitis (CRS) that is refractory to maximal medical and surgical therapy should be evaluated for other primary conditions. Cystic fibrosis (CF), primary immunodeficiency (PID), and primary ciliary dyskinesia (PCD) are potential risk factors for refractory CRS. These conditions present with variable disease severity and diagnosis may be delayed into adulthood. We report a case of a mother-daughter pair with CRS refractory to maximal medical management. The patients were further evaluated and found to have features consistent with CF, PID, and PCD. All 3 are rare disorders and thought to cause CRS in isolation. Patients with refractory CRS should be further evaluated to identify alternative diagnoses and ensure proper management. Refractory CRS may be multifactorial, with different risk factors simultaneously contributing to its persistence.
RESUMEN
BACKGROUND: The family, as the basic socialization environment, is a complex dynamic system that - as a whole and through its subsystems - is in relationships with other social systems (Bagdy in Family socialization and personality disorders. Nemzeti Tankönyvkiadó, Budapest, 2002; Lakatos et al. in Mentálhigiéné és Pszichoszomatika 21(1):56-85, 2020). The system with which the family system has long-term relationships is the work system/environment. Creating and maintaining a work-life balance has become a central issue in our societies, as they are two of the most organising forces, and reconciling them is a very difficult task due to the demands and expectations coming from both directions, often simultaneously (Makra et al. in Magyar Pszichológiai Szemle 67(3):491-518, 2012). This kind of "double burden" primarily affects women, but their increasing role in the labour market is not necessarily followed by an equal sharing of work within family life (Engler et al. in Work-life balance in women's careers. In: Tardos K, Paksi V, Fábri Gy (eds) Scientific careers in the early 21st century. Belvedere Meridionale, Szeged, pp 114-126, 2021). We hypothesise that involvement in work negatively correlates with work-life balance, making it more difficult to integrate into the family. It was expected that the relationship between the number of children and mothers' professional involvement would be negative. A positive correlation was expected between the age of the youngest child and the mothers' work involvement. On the other hand, a family united by cohesion and resilience leads to higher job satisfaction. METHODS: For the present analysis, we analysed the relationships between work-family conflict and family structure in working mothers with children in a sample of 273 participants. The self-reported questionnaire included demographic data and 2 standard questionnaires: the Work-Family Conflict Questionnaire and the Olson-Family Test (FACES-IV.). The study was conducted in Hungary. RESULTS: No significant relationship was found between work involvement and work-family conflict. A negative relationship was observed between work involvement and family involvement. Similiarily, no significant relationship was found between the number of children, the age of the youngest child and work involvement, contrary to expectations. The findings indicate a positive relationship between good family cohesion, flexibility and job satisfaction. CONCLUSION: Striking a work-family balance is a challenging process for families with young children, especially working mothers. A mutually negative relationship between work and family involvement has been shown. The importance of a well-functioning family, with adequate cohesion and flexibility, is reflected in family and job satisfaction. The relationship between work-to-family conflict and job involvement is moderated significantly only when family flexibility is low. The results from the present pilot study indicate important relationships between variables and point to further research directions worth investigating in a larger sample in the future.

BACKGROUND: Ex vivo heart perfusion (EVHP) of donation after circulatory death (DCD) hearts has become an effective strategy in adults; however, the small circulating volume in pediatrics poses the challenge of a low-hemoglobin (Hb) perfusate. We aimed to determine the impact of perfusate Hb levels during EVHP on DCD hearts using a juvenile porcine model. METHODS: Sixteen DCD piglet hearts (11-14 kg) were reperfused for 4 h in unloaded mode followed by working mode. Metabolism, cardiac function, and cell damage were compared between the low-Hb (Hb, 5.0-5.9 g/dL; n = 8) and control (Hb, 7.5-8.4 g/dL; n = 8) groups. Between-group differences were evaluated using 2-sample t-tests or Fisher's Exact tests. RESULTS: During unloaded mode, the low-Hb group showed lower myocardial oxygen consumption (P < 0.001), a higher arterial lactate level (P = 0.001), and worse systolic ventricular function (P < 0.001). During working mode, the low-Hb group had a lower cardiac output (mean, 71% versus 106% of normal cardiac output, P = 0.010) and a higher arterial lactate level (P = 0.031). Adjusted cardiac troponin-I (P = 0.112) did not differ between the groups. Morphological myocyte injury in the left ventricle was more severe in the low-Hb group (P = 0.028). CONCLUSIONS: Low-Hb perfusate with inadequate oxygen delivery induced anaerobic metabolism, resulting in suboptimal DCD heart recovery and declined cardiac function. Arranging an optimal perfusate is crucial to organ protection, and further endeavors to refine the priming volume of EVHP or the transfusion strategy are required.
RESUMEN
Background: Cystic echinococcosis (CE) or hydatid disease caused by the cestode Echinococcus granulosus sensu lato is an uncommon infection in Canada especially among children. There are limited reports describing the clinical presentation and management in Canadian children. Methods: The medical records of all children diagnosed with CE at a quaternary paediatric centre in Ontario between January 1988 and August 2021 were retrospectively reviewed. The clinical course, management, and outcomes of each case were summarized. Results: We report two paediatric cases of cystic echinococcosis (CE) in detail and review four additional cases seen at our institution over 33.5 years. The first case was a previously healthy 12-year-old boy with pulmonary CE resulting in unilateral lung collapse and mediastinal shift, who was presumedly infected while living in the Middle East. The second case was a previously healthy 3-year-old girl with pulmonary CE acquired locally in southern Ontario. Four other cases of CE with hepatic involvement (median age 12.5 years) were identified during the study period. Five out of six patients received both surgical and medical therapy. Conclusion: CE is a rare but serious disease seen in southern Canada that has historically been associated with travel or migration. Due to changes in urban wildlife landscapes and increased global migration, CE may become more prevalent in Canadian children. We describe the first locally acquired case in rural southern Ontario diagnosed at our centre. Prompt recognition of this infection in children by health care providers is important to prevent morbidity and mortality.
Historique: L'échinococcose kystique (ÉK), ou hydatidose, causée par le cestode Echinococcus granulosus sensu lato, est une infection peu courante au Canada, particulièrement chez les enfants. Peu de rapports en décrivent la présentation clinique et la prise en charge chez les enfants canadiens. Méthodologie: Les auteurs ont procédé à l'analyse rétrospective des dossiers médicaux de tous les enfants ayant reçu un diagnostic d'ÉK dans un centre pédiatrique de soins quaternaires ontarien entre janvier 1988 et août 2021. Ils ont résumé l'évolution clinique, la prise en charge et le résultat clinique de chaque cas. Résultats: Les auteurs font un compte rendu détaillé de deux cas pédiatriques d'ÉK et analysent quatre autres cas observés à leur établissement sur une période de 33,5 ans. Le premier cas d'ÉK pulmonaire a touché un garçon de 12 ans auparavant en santé, probablement infecté alors qu'il habitait au Moyen-Orient, et a entraîné un collapsus pulmonaire unilatéral et une déviation médiastinale. Le deuxième cas d'ÉK pulmonaire a été observé chez une fillette de trois ans auparavant en santé qui a été infectée dans le sud de l'Ontario. Les auteurs ont relevé quatre autres cas d'ÉK comportant une atteinte hépatique (âge médian de 12,5 ans) pendant la période de l'étude. Cinq des six patients ont reçu à la fois un traitement chirurgical et médical. Conclusion: L'ÉK est une maladie rare, mais grave dans le sud du Canada. Elle était auparavant associée à un voyage ou une migration. En raison des changements aux paysages fauniques urbains et de la migration mondiale accrue, elle pourrait devenir plus prévalente chez les enfants canadiens. Les auteurs décrivent les premiers cas d'acquisition dans les régions rurales du sud de l'Ontario, diagnostiqués à leur centre. Il est important que les dispensateurs de soins dépistent cette infection rapidement chez les enfants pour éviter la morbidité et la mortalité.
RESUMEN
BACKGROUND: Dementia is a significant health issue worldwide. Mild cognitive impairment (MCI) can transform into dementia over time. General practitioners (GPs) may be the first to notice the cognitive deficit; therefore, it is crucial for them to have access to a screening test that can be administered quickly and efficiently. We explored the Hungarian version of the Test Your Memory self-administered dementia screening test in general practice for the early detection of dementia and cognitive impairment. METHODS: In the four Hungarian cities with medical universities, 368 patients over the age of 50 attending GPs filled out the questionnaire within the framework of our cross-sectional study. RESULTS: The total scores of the test showed a significant correlation with education and type of occupation and a significant negative correlation with age. The results of this research showed that the clock drawing and recall subtest scores deteriorate at the earliest age. CONCLUSION: The test can be filled out in a GP's office easily and two of its subtests can raise the possibility that patients may need further assessment, especially if they have symptoms, at an earlier age than the other subtests.
RESUMEN
Background Heart transplantation with a donation after circulatory death (DCD) heart is complicated by substantial organ ischemia and ischemia-reperfusion injury. Exenatide, a glucagon-like peptide-1 receptor agonist, manifests protection against cardiac ischemia-reperfusion injury in other settings. Here we evaluate the effects of exenatide on DCD hearts in juvenile pigs. Methods and Results DCD hearts with 15-minutes of global warm ischemia after circulatory arrest were reperfused ex vivo and switched to working mode. Treatment with concentration 5-nmol exenatide was given during reperfusion. DCD hearts treated with exenatide showed higher myocardial oxygen consumption (exenatide [n=7] versus controls [n=7], over 60-120 minutes of reperfusion, P<0.001) and lower cardiac troponin-I release (27.94±11.17 versus 42.25±11.80 mmol/L, P=0.04) during reperfusion compared with controls. In working mode, exenatide-treated hearts showed better diastolic function (dp/dt min: -3644±620 versus -2193±610 mm Hg/s, P<0.001; Tau: 15.62±1.78 versus 24.59±7.35 milliseconds, P=0.02; lateral e' velocity: 11.27 ± 1.46 versus 7.19±2.96, P=0.01), as well as lower venous lactate levels (3.17±0.75 versus 5.17±1.44 mmol/L, P=0.01) compared with controls. Higher levels of activated endothelial nitric oxide synthase (phosphorylated to total endothelial nitric oxide synthase levels: 2.71±1.16 versus 1.37±0.35, P=0.02) with less histological evidence of endothelial damage (von Willebrand factor expression: 0.024±0.007 versus 0.331±0.302, pixel/µm, P=0.04) was also observed with exenatide treatment versus controls. Conclusions Acute treatment of DCD hearts with exenatide limits myocardial and endothelial injury and improves donor cardiac function.

BACKGROUND: Our study aimed to assess the differences between domestic and international students in terms of social support, vital exhaustion, and depression during the period of COVID-19 and to examine the relationships and potential effects of these factors on each other. METHODS: The online cross-sectional survey was conducted via Google Forms® at three time intervals during the pandemic. RESULTS: Here, 1320, 246, and 139 students completed our questionnaires in the different time intervals. The international students reported significantly lower values in terms of perceived social support. Concerning depression, the international female students reported higher values than the domestic female students. Significant correlations were found in both samples between vital exhaustion and depression, as well as between perceived social support and depression. CONCLUSION: In this study, the international students reported lower levels of perceived social support and higher levels of depression, particularly among females. The correlations between depression, social support, and vital exhaustion might highlight protective and risk factors. These findings emphasize the importance of addressing social support and mental health among university students, especially among international students who have a difficult time finding social support during times of stress, such as during the COVID-19 pandemic.

BACKGROUND: Our study aimed to examine whether health anxiety, social support, and ways of coping relate to dissociation directly or only through the mediation of perceived stress, moderated by the time of measurement (lockdown). We investigated the effect of perceived stress on different forms (sub-scales) of dissociation. METHODS: A cross-sectional survey was conducted by an online form at two points in time: the beginning and the later stage of the COVID-19 pandemic. RESULTS: We received a total of 1711 responses. Perceived stress moderately correlated with dissociation in both international and Hungarian samples. Health anxiety showed a strong direct and indirect correlation with dissociation. Regarding social support, the support of family significantly decreased the dissociative experiences in the Hungarian sample mediated by perceived and direct stress. In the international sample, goal-oriented coping strategies strongly decreased all dissociation scales in the first measurement, through the mediation of perceived stress. As for the Hungarian sample, positive thinking was found to decrease dissociation by decreasing perceived stress. CONCLUSION: health anxiety, coping, and social support appeared to influence dissociation directly and through the mediation of perceived stress. Social support, mainly support of the family and problem-focused coping strategies may decrease the level of stress, this way decreasing dissociative behavior.

AIMS: The aim of the present study was to determine the clinical significance of an incidental finding of eosinophilia (EOS) and chronic inflammatory infiltrate (CINF) in rectal biopsies of children investigated for suspected Hirschsprung disease (HSCR). METHODS: A retrospective study (2000-2010) of children incidentally found to have EOS and CINF was performed. HSCR cases were excluded. Presence of gastrointestinal (GI) symptoms and nutritional status (weight-for-age z score) were investigated and compared with a matched cohort with normal biopsy. RESULTS: Of 364 children undergoing rectal biopsy for suspected HSCR, 109 had confirmed HSCR, whereas 255 children had normal ganglia. Forty-four of 255 (17%) children had EOS and/or CINF incidentally reported and are the subject of the present study. In 13 of 44 (29%) children, the biopsy was performed neonatally. At follow-up (4.6 months [1-22]), 21 (48%) had food and/or milk allergy, 30 (68%) had constipation and/or other GI symptoms. There was no change in weight-for-age z score (Pâ=â0.85) at follow-up and 8 (20%) had failure to thrive. Only 10 of 44 (Pâ=â0.0001 vs patients with EOS and/or CINF) children with normal biopsy had persistent constipation at follow-up (9.7 months [0.5-84.7]) and 1 patient had atopy. Patients with normal biopsy exhibited an increase in weight-for-age z score at follow-up (Pâ=â0.003) and only 3 patients (7%) had failure to thrive. CONCLUSIONS: EOS and CINF are found in 17% of children who had rectal biopsies negative for HSCR. Half of these children will need further medical input for the presence of persisting GI symptoms, food/milk allergy and failure to thrive, and the possibility to develop inflammatory bowel disease later in life.
