Abstract
PURPOSE Multiple endocrine neoplasia Type 2A (MEN2A) can occur with Hirschsprung disease (HD) due to mutation in the RET proto-oncogene, with the majority developing medullary thyroid carcinoma (MTC). Given the comorbidity, many parents have contacted us to share concerns and unfortunate experiences about the prevalence rates of MEN2A/MTC in patients with HD. The aim is to determine the prevalence rate of patients with HD and MEN2A or medullary thyroid carcinoma, respectively. METHODS This is a cross-sectional study of the COSMOS database from January 01, 2017, to March 08, 2023. The database was searched for patients diagnosed with MEN2A, MTC, and HD. IRB exemption was provided (COMIRB #23-0526). RESULTS The database contained 183,993,122 patients from 198 contributing organizations. The prevalence of HD and MEN2A was 0.00002%, and for HD and MTC was 0.000009%. One in 66 patients (1.5%) with MEN2A also had HD. One in 319 patients (0.3%) in the HD group had MEN2A. One in 839 patients (0.1%) within the HD population had MTC. CONCLUSION The prevalence of MTC and HD or MEN2A and HD in the study population was low. Considering that almost all MEN2A patients have a positive family history, this data does not support the general genetic testing of HD patients.

Abstract
This article describes the common methods to study long-term outcomes in patients who have undergone major surgery in newborn period. It also sums up today's knowledge on the long-term outcome of some classic newborn surgical conditions. The analysis of long-term outcomes is important to pediatric surgeons. Knowledge of long-term outcome can guide the patient's management and principles of the follow-up throughout the patient's childhood. It also aims to give the parents of the patient a realistic picture on the development of their child. Recent data have shown that many patients who have undergone major surgery during early childhood have significant functional aberrations at adult age. Some of these have a profound influence on the quality of life of these patients.

Abstract
PURPOSE Hirschsprung disease (HSCR) has previously been associated with increased risk of medullary thyroid cancer. The aim of this study was to assess the overall risk of malignancies in patients with Hirschsprung disease in a population-based cohort. METHODS This was a nationwide, population-based cohort study. The study exposure was HSCR and the study outcome was malignancy. The cohort included all individuals with HSCR registered in the Swedish National Patient Register between 1964 and 2013 and ten age- and sex-matched controls per patient, randomly selected from the Population Register. Data were linked with the Swedish National Cancer Register to identify individuals with malignancy diagnosis. RESULTS The cohort comprised 739 individuals with HSCR (565 male) and 7390 controls (5650 male). Median age of the cohort was 19 years (range 2-49). In total nine (1.2%) individuals in the exposed cohort were diagnosed with malignancies compared to 57 (0.8%) in the non-exposed cohort (p = 0.195). Median age at malignancy diagnosis was 3 years (range 0-46) in the exposed group, compared to 23 (range 0-42), p = 0.132. No cases with medullary carcinoma of the thyroid were found in this cohort. CONCLUSIONS There was no significant difference in risk of malignancies in the exposed group compared to the unexposed group.

Abstract
The objective of this study was to assess the occurrence of thyroid cancer and co-occurring RET mutations in a population-based cohort of adult Hirschsprung disease (HD) patients. All 156 patients operated for HD in a tertiary center during 1950-1986 were followed for thyroid malignancies up to 2010 through the nationwide Finnish Cancer Registry. Ninety-one individuals participated in clinical and genetic screening, which included serum calcitonin and thyroid ultrasound (US) with cytology. Exons 10, 11, 13, and 16 were sequenced in all, and all exons of RET in 43 of the subjects, including those with thyroid cancer, RET mutations, suspicious clinical findings, and familial or long-segment disease. Through the cancer registry, two cases (aged 35 and 37 years) of medullary thyroid cancer (MTC) were observed; the incidence for MTC was 340-fold (95% CI 52-1600) compared with average population. These individuals had C611R and C620R mutations in exon 10. One papillary thyroid cancer without RET mutations was detected by clinical screening. Four subjects (aged 31-50 years) with co-occurring RET mutations in exons 10 (C609R; n=1) and 13 (Y791F, n=3) had sporadic short-segment HD with normal thyroid US and serum calcitonin. Three novel mutations and five single-nucleotide polymorphisms were found outside exons 10 and 13 without associated signs of thyroid cancer. MTC-associated RET mutations were restricted to exons 10 and 13 affecting ∼5% of unselected adults with HD. Clinical thyroid assessment did not improve accuracy of genetic screening, which should not be limited to patients with familial or long-segment disease.

Abstract
Despite significant developments in the understanding of the pathologic anatomy and physiology of Hirschsprung's disease (HD), the results of surgical therapy remain far from perfect. The functional defects and psychosocial difficulties that occur commonly in children with HD are passed on to adulthood in a significant proportion of patients. Recent prospective and adequately controlled cross-sectional studies reveal that constipation and fecal soiling are common late sequelae in adulthood. HD patients show uniformly lower scores of overall bowel function than healthy control subjects. Functional outcome and quality of life may be interrelated and deteriorate with increasing age. Despite these shortcomings, at adult age, most of the HD patients appear to be able to function as normal members of the society in terms of psychosocial, occupational, and recreational activities. Patients are at risk of developing related conditions, such as cancer, that require planning of specific screening programs. Many of the long-term problems that these patients experience are specific to HD. The follow-up of HD patients should be performed by medical personnel familiar with the disease, preferably in a specialized referral center, and the follow-up should continue beyond childhood.

Abstract
PURPOSE Inactivating germline mutations in the RET proto-oncogene are the major genetic cause of Hirschsprung's disease (HD). In some cases, HD can be associated with medullary thyroid carcinoma (MTC) that is commonly caused by activating RET mutations. METHODS The retrospective and prospective genetic analyses of 157 patients with HD operated on between December 1979 and June 2011 were carried out. DNA was isolated from peripheral leukocytes. HD patients and family members were tested for RET mutations by direct sequencing and single-strand conformation polymorphism methods. RESULTS RET mutations were detected in 16 patients (10%). Association with MTC was found in two families, other eight families had a mutation with potentially high risk of MTC development and four novel mutations were detected. Total colonic aganglionosis was noted to have a high mutation detection rate (40%). Three patients underwent total thyroidectomy (two had clinical manifestation of MTC, one C-cell hyperplasia). CONCLUSION Results show the benefit of systematic RET mutation screening in HD patients in order to identify the risk of MTC in the preclinical stage of the disease. All patients should be tested for RET mutations at least in exon 10, and now additionally in exon 11 and 13, as well.

Abstract
BACKGROUND RET germline mutations predispose to the development of inherited cancer syndrome multiple endocrine neoplasia type 2 (MEN2). Several variants of the RET proto-oncogene including G691S and S904S have been suggested to act as genetic modifiers at the age of onset ofMEN2. AIM The aim of this study is to characterize clinically and molecularly 7 Cypriot patients with familial medullary thyroid carcinoma (FMTC) and 1 with MEN2A and also to determine the allelic frequencies of the RET variants G691S and S904S. SUBJECTS AND METHODS Seven probands from FMTC families and 1 from MEN2A were screened for the presence of RET mutations and the G691S and S904S variants. Additionally, 226 healthy Cypriots, who served as controls were analysed in an attempt to compare the frequencies of G691S and S904S RET variants to those observed in the 8 patients. RESULTS The clinical diagnosis of the probands was based on clinical presentation and supported with biochemical findings. The germline C618R mutation of exon 10 was identified in all 8 probands and in 15 relatives from 7 different families. No significant difference in the G691S/S904S variants allele frequencies between patients (4/16 or 25%) and controls (124/452 or 27.4%) was found. CONCLUSIONS Mutational screening of the RET gene identified a common mutation (C618R) in all 8 (7 FMTC and 1 MEN2A) unrelated Cypriot patients which may be explained by a founder effect. Additionally, no association of the G691S/S904S variants was linked with the disease.

Abstract
Anorectal malformations (ARMs) and Hirschsprung disease (HD) are the most common congenital colorectal defects in the newborn. The outcomes of HD and ARMs have improved significantly because of improved understanding of the pathologic anatomy and physiology of these defects and of the modern surgical techniques. Still, many patients suffer from defective bowel control even as adults. Some of these also have problems with urinary control and sexual functions. The functional problems are more pronounced in patients with ARMs. Compared with healthy people, both patients with ARMs and those with HD have limitations in their quality of life. Inferior quality of life is more common in patients with ARMs. There are very few published data on long-term outcome of adults with ARMs and HD. The effect of aging on the functional outcome and quality of life remains unclear, although some preliminary data suggest that the bowel function and quality of life may deteriorate with aging.

Abstract
Hirschsprung disease (HD) and anorectal malformations (ARMs) result from alterations in hindgut development. It has long been recognized that both recur in families and thus result, at least in part, from genetic factors. Progress in the understanding of the genetic basis of HD has been made by the application of findings from genetic animal models of altered enteric nervous system development to human beings. Several genes have been shown to be important for human enteric nervous system development, and current work is progressing to identify genetic interactions that may explain the variable phenotype of HD. By contrast, understanding of the genetic factors underlying ARMs is much less developed. We and others have shown that genetic factors play an important role in the pathogenesis of ARMs, and many mouse genetic models suggest molecular pathways that may be altered in ARMs.

Abstract
Multiple endocrine neoplasia (MEN) type 2 syndromes are autosomal dominant clinical associations characterized by a common clinical feature, medullary thyroid carcinoma (MTC). The ability to accurately predict the risk by genetic RET proto-oncogene analysis has resulted in the active follow-up of children at risk for developing early metastatic tumours and which can be prevented by prophylactic thyroidectomy. The C634 and M918T mutations (associated with MEN2A and MEN2B, respectively) are particularly associated with early aggressive behavior and distant metastatic spread requiring early intervention. RET is known to be involved in cellular signalling processes during development and controls the survival, proliferation, differentiation and migration of the enteric nervous system (ENS) progenitor cells, as well as the survival and regeneration of sympathetic neural and kidney cells. The centrality of RET in the etiology of both MEN2 and HSCR is now well established with fairly consistent associations existing between RET genotype and phenotype in MEN2. The relationship between Hirschsprung's disease (HSCR) MEN2 syndromes appears to be a highly significant one, sharing a common etiological factor in the RET proto-oncogene. It is now well accepted that most HSCR arises from loss of function, RET mutations, RET haploinsufficiency or RET polymorphisms and haplotypes of the RET promotor region. MEN2 syndromes result from gene up regulation due to germline activating mutations in the RET proto-oncogene (1:500,000). MTC is mostly associated with variations in the 5 cysteine RET radicals and codon-risk management protocols are of considerable value but not infallible. Oncogenic RET mutations may, however, vary between specific population groups. RET analysis in MEN has revolutionized the management of children of MEN2 and allowed surgical prediction and prophylaxis to take place. We discuss the role of genetic testing and possible guidelines for the management of patients from MTC families. The future appears full of promise and the current evaluation of RET-targeting tyrosine kinase and other inhibitors are of considerable interest in the management of these conditions.

Abstract
Hirschsprung's disease (HD) can be associated with the development of neuroendocrine tumours such as medullary thyroid carcinoma (MTC). The RET proto-oncogene is the major gene responsible for both HD and MTC. Mutations in exon 10 (codons 609, 611, 618, 620) were found in patients with co-occurrence of HD and MTC. The aim of the study was to screen the MTC risk in patients with HD. The prospective and retrospective genetic analyses comprised 56 HD patients (41 males, 15 females, aged 0-47). The prospective subgroup of patients consisted of 34 patients (25 boys, 9 girls) operated on between June 2003 and December 2005. The retrospective subgroup comprised 22 patients (16 boys, 6 girls) of 194 patients who were operated on between December 1979 and May 2003, non-systematically chosen preferably for total colonic aganglionosis (TCA). DNAs were isolated from blood and resected segments of aganglionic bowel. The HD patients and nine available family members (2 HD) were tested for RET mutations in exons 10, 11, 13, 14, 15 and 16. Direct double-stranded fluorescent sequencing revealed typical germline heterozygous MTC risk RET mutations in 3/56 (5.4%) female HD patients: Cys609Tyr, Cys620Arg (both exon 10) and Tyr791Phe (exon 13). Two of these patients had TCA and one patient had classical type of HD. One TCA patient developed clinical stage of MTC and underwent total thyroidectomy (TTE). The other two RET positive HD patients (aged 7 and 25 years) are screened for calcitonin level and they are without TTE till now. Two family members (mothers of TCA patients) with detected RET mutation underwent prophylactic TTE with MTC finding. Results showed the benefit of systematic RET mutation screening in HD patients in order to identify the risk of MTC in preclinical stage of the disease in patients with HD and their family members. We recommend to investigate not only exon 10 but also exon 13.
