Clinics (Sao Paulo) 2023; 78:100198. [PMID: 37075514 PMCID: PMC10126911 DOI: 10.1016/j.clinsp.2023.100198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 01/31/2023] [Accepted: 03/28/2023] [Indexed: 04/21/2023] Open
Abstract
BACKGROUND Hirschsprung's Disease (HD) is characterized by intestinal sub-occlusion and the absence of enteric ganglion cells. A rectal biopsy examination is performed to confirm the diagnosis. In a recent study, we demonstrated that the analysis of 60 sections of rectal mucosa and submucosa stained by H&E may ensure a 90% diagnostic accuracy. Although the need to analyze so many sections makes the process of reading the slides more time-consuming, this encouraged us to study their distribution in the healthy rectal submucosa, to simplify the diagnosis. OBJECTIVES To develop a method that facilitates HD diagnosis by studying the distribution of ganglion cells in the submucosal plexus. METHODS Using the calretinin technique, we studied the distribution of plexuses in 60 fragments of rectal submucosa from 19 cadavers. After the study, the reading method created was used for diagnosis in 47 cases of suspected HD, using H&E staining. The accuracy was verified by comparing the results obtained with H&E to those obtained with the acetylcholinesterase technique, the golden standard in our laboratory. RESULTS The study of submucosal plexus distribution showed that just by examining the submucosal region every 20 µm, approximately, it is possible to locate a ganglionic plexus, and we have already been able to diagnose HD with 93% accuracy. CONCLUSION The study of ganglion cell distribution enabled the creation of a simplified method for reading the slides. The method applied achieved good accuracy and it can be used as an alternative method in HD diagnosis.

Abstract
BACKGROUND Hirschsprung's disease (HD) is a congenital disorder affecting neonates that presents with distal intestinal obstruction. It is the most common type of anorectal malformation. Treatment of HD consists of surgical removal of the distal colon including the most distal aganglionic segment, the transitional zone, and a prudent length of proximal colon that is determined during the surgical procedure to be normally ganglionated by intraoperative demonstration of normal ganglion cells up to and including the surgical resection margin. METHODS In a retrospective study of formalin-fixed paraffin-embedded colon tissue from the proximal resection margin (PRM) of 209 HD patients, we made morphometric measures and detected immature ganglion cells defined as dysmorphic by immunohistochemical demonstration of cytoplasmic neurofilament (NF). RESULTS The majority of NF-positive ganglion cells in HD patients appeared immature, with less cytoplasm. Occasional positive ganglion cells in the same patients appeared mature with abundant eosinophilic cytoplasm, Nissl bodies, prominent nucleoli, and adjacent glial cells. Patients with NF-positive ganglion cells in the myenteric plexuses at the PRM may have poor postoperative recovery. CONCLUSION We propose that NF expression in dysmorphic ganglion cells at the PRM may predict poor outcome after pull-through surgery for HD.

Pathogenesis of chronic constipation in a Polish group of paediatric patients - an attempt to create the optimal histopathological diagnostic protocol. GASTROENTEROLOGY REVIEW 2019; 14:109-111. [PMID: 31616524 PMCID: PMC6791142 DOI: 10.5114/pg.2019.85894] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Accepted: 11/19/2018] [Indexed: 01/25/2023]
Abstract
Introduction Histopathological diagnosis of chronic constipation in children is difficult and time-consuming because the aetiology of the problem is heterogenous. Aim To create the optimal immunohistochemical (IHC) and histological diagnostic protocol using novel antibodies and assessing precisely their patterns. Material and methods Twenty-eight paediatric patients were enrolled to the study. The study group consisted of the following: 9 patients with confirmed Hirschsprung’s disease (HD), 11 patients with desmosis of the colon (DC) (3) or with chronic constipation of unknown aetiology (3), and eight children operated on due to other problems. Retrospective analysis of full-thickness material from the large intestine was performed. In each specimen the number of ganglion cells was estimated per square millimetre as well as the number of submucosal and intramuscular ganglion cells per ganglion. The following IHC and histological stains were also performed: calretinin, CD117, picrosirius, and trichrome gomori. Patterns (nuclear vs. cytoplasmic vs. membranous) and intensity (strong vs. faint) of the stainings were analysed. Results There was no statistically significant difference between groups while comparing the intensity and pattern of each staining, except HD (no staining due to lack of ganglion cells), p > 0.001. Calretinin was positive in each patient with ganglion cells; however, it did not unequivocally stain all cells identified in routine haematoxylin and eosin staining. Conclusions Calretinin is helpful in identifying ganglion cells; however, it cannot replace an experienced paediatric pathologist. In children with chronic constipation it is worth obtaining a full thickness intestinal biopsy in order to perform additional histological and immunohistochemical stains starting with picrosirius red.

Abstract
We present the case of a 14-year-old male with a history of small bowel transplantation for long segment Hirschsprung's disease who underwent Duhamel ileorectal pull-through procedure. In post-transplant, the patient had no restrictions and was not TPN-dependent. To improve his quality of life, he and his family were interested in closing the ileostomy and undergoing pull-through surgery. The complexity of the case includes the presence of an aganglionic rectal segment-a short root of the mesentery due to the small bowel transplant-and significant immunosuppression. At the moment, he is continent, doing well, and has not had any remarkable complications.

Abstract
RATIONALE All the enteric ganglion cells are fully mature by 2 to 5 years of age in human. No one had reported the presentation of immature enteric ganglion cells in elder ones. Colorectal carcinoma is also rare in the adolescent population. The coincidence of these 2 rare events in a 13-year-old boy has never been reported elsewhere, which may suggest some linkage between them. PATIENT CONCERN A 13-year-old boy presented with progressive abdominal pain and melena for 3 months. Computed tomography (CT) scan and endoscopic ultrasonography showed significant abnormality in the transverse colon characteristic of marked mural thickening. The biopsy results indicated signet ring cell carcinoma. DIAGNOSES A 13-year-old male patient with advanced colon signet ring cell carcinoma. In addition, immature but not mature ganglion cells could be observed in almost all of the slices of the resected nontumorous area of the specimen. INTERVENTIONS The transverse colon tumor was resected and the subsequent histopathological examination confirmed the diagnosis of primary colon signet ring cell carcinoma. Then the patient received adjuvant chemotherapy and biological target therapies subsequently. OUTCOMES After 6 cycles of adjuvant chemotherapy and biological target therapies, metastasis was however detected within a year. LESSONS In this case, a 13-year-old male patient with advanced colon signet ring cell carcinoma were presented. Unexpectedly, immature ganglion cells could be observed in almost all of the slices of the resected nontumorous area of the specimen. It is critical to raise medical awareness and improve the diagnosis and treatment of the signet ring cell carcinoma. This malignancy and the immature ganglion cells may be associated, possibly caused by some unidentified genetic defects. Genome sequencing, histopathological examination, and long-term follow-up of young patients with related diseases, would help further reveal the potential relationship between tumorigenesis and ganglion cells' immaturity, contributing to understanding the molecular mechanisms.

Abstract
On the occasion of the 100th anniversary of Dr. Harald Hirschsprung's death, there is a worldwide significant research effort toward identifying and understanding the role of genes and biochemical pathways involved in the pathogenesis as well as the use of new therapies for the disease harboring his name (Hirschsprung disease, HSCR). HSCR (aganglionic megacolon) is a frequent diagnostic and clinical challenge in perinatology and pediatric surgery, and a major cause of neonatal intestinal obstruction. HSCR is characterized by the absence of ganglia of the enteric nervous system, mostly in the distal gastrointestinal tract. This review focuses on current understanding of genes and pathways associated with HSCR and summarizes recent knowledge related to micro RNAs (miRNAs) and HSCR pathogenesis. While commonly sporadic, Mendelian patterns of inheritance have been described in syndromic cases with HSCR. Although only half of the patients with HSCR have mutations in specific genes related to early embryonic development, recent pathway-based analysis suggests that gene modules with common functions may be associated with HSCR in different populations. This comprehensive profile of functional gene modules may serve as a useful resource for future developmental, biochemical, and genetic studies providing insights into the complex nature of HSCR.
