Adult-onset megacolon with focal hypoganglionosis: A detailed phenotyping and prospective cohort study. Neurogastroenterol Motil 2023; 35:e14630. [PMID: 37392417 DOI: 10.1111/nmo.14630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 05/15/2023] [Accepted: 06/05/2023] [Indexed: 07/03/2023]
Abstract
BACKGROUND In this prospective cohort study, we evaluated features of "adult-onset megacolon with focal hypoganglionosis." METHODS We assessed the radiologic, endoscopic, and histopathologic phenotyping and treatment outcomes of 29 patients between 2017 and 2020. Data from community controls, consisting of 19,948 adults undergoing health screenings, were analyzed to identify risk factors. Experts reviewed clinical features and pathological specimens according to the London Classification for gastrointestinal neuromuscular pathology. KEY RESULTS The median age of the patients with adult-onset megacolon with focal hypoganglionosis at symptom onset was 59 years (range, 32.0-74.9 years), with mean symptom onset only 1 year before diagnosis. All patients had focal stenotic regions with proximal bowel dilatation (mean diameter, 78.8 mm; 95% confidence interval [CI], 72-86). The comparison with community controls showed no obvious risk factors. Ten patients underwent surgery, and all exhibited significant hypoganglionosis: 5.4 myenteric ganglion cells/cm (interquartile range [IQR], 3.7-16.4) in the stenotic regions compared to 278 cells/cm (IQR, 190-338) in the proximal and 95 cells/cm (IQR, 45-213) in the distal colon. Hypoganglionosis was associated with CD3+ T cells along the myenteric plexus. Colectomy was associated with significant symptom improvement compared to medical treatment [change in the Global Bowel Satisfaction score, -5.4 points (surgery) vs. -0.3 points (medical treatment); p < 0.001]. CONCLUSIONS AND INFERENCES Adult-onset megacolon with focal hypoganglionosis has distinct features characterized by hypoganglionosis due to inflammation. Bowel resection appears to benefit these patients.

Abstract
A reduced and limited number of myenteric ganglia and low acetylcholinesterase activity in the lamina propria characterizes an unusual form of intestinal innervation disorder known as acquired or adult-onset hypoganglionosis. Only a few cases have been observed in adults, while the majority are diagnosed in infancy or youth. We report a rare case of colonic hypoganglionosis that presented as sigmoid volvulus in a 25-year-old female brought in to the ER. She underwent endoscopic decompression but developed a massive sigmoid volvulus with proximal colon dilatation. It was decided to do a total colectomy with an end ileostomy. The diagnosis was confirmed by histopathology, which revealed acquired hypoganglionosis. In order to prevent delayed or emergency presentation and the development of a stoma, the diagnosis of hypoganglionosis must be confirmed with full-thickness biopsies from all affected parts of the large bowel. Hypoganglionosis is rarely present, so young patients with a history of chronic constipation must be treated with a high index of suspicion.

Abstract
BACKGROUND AND PURPOSE Autonomic dysfunction has been occasionally described in varicella-zoster virus (VZV) infection, while few systematic reviews are available. We systematically review autonomic dysfunction due to VZV infection. METHODS This study followed the PRISMA guideline, and three databases were researched and included cross-sectional studies in full-length publications in the English language using appropriate search keywords. RESULTS A total of 102 articles were identified initially; finally 45 studies were used for review, comprising pupillomotor dysfunction in 4, sudomotor dysfunction in 2, cardiovascular dysfunction in 2, gastrointestinal dysfunction in 14, and urogenital dysfunction in 23. They can be summarized as (1) VZV infection rarely produces orthostatic hypotension, which involves diffuse sympathetic dysfunction by polyneuropathy. (2) In contrast, VZV infection produces dysfunction of the bladder and the bowel, which involves segmental parasympathetic or sympathetic dysfunction by dorsal root ganglionopathy. CONCLUSIONS Awareness of VZV-related autonomic dysfunction is important, because such patients may first visit a gastroenterology or urology clinic. Close collaboration among neurologists, dermatologists, gastroenterologists, and urologists is important to start early antiviral agents and maximize bowel and bladder care in such patients.

Abstract
A 64-year-old woman was admitted to hospital with persistent abdominal pain. She had been hospitalized with similar symptoms on five occasions during a period of 2 years. Computed tomography revealed dilatation and fecal impaction from the ileum to the transverse colon. A barium enema and simultaneous ileus tube radiography showed a narrow segment of descending-sigmoid colon. Colonoscopy showed no mucosal change. Her symptoms did not improve with conservative therapy, so descending and sigmoid colectomy was performed. Histologic examination showed disappearance of ganglion cells; axon of Meissner's plexuses was present, and the number of Auerbach's plexuses was decreased. The definitive diagnosis was segmental hypoganglionosis (SH) of the colon. The postoperative course was uneventful, and the functional result was positive at 1 year postoperatively. SH is extremely rare; however, surgical intervention is expected to be of benefit. Therefore, it is important to keep SH in mind when treating patients with chronic obstruction of the left side of the colon.

Abstract
BACKGROUND Cytomegalovirus (CMV) colitis is usually seen in immunocompromised patients with risk factors such as human immunodeficiency virus infection, solid organ transplant, inflammatory bowel disease, or malignancy. Therefore, many clinicians usually do not consider the possibility of CMV colitis in immunocompetent patients. We reported a rare case of segmental colonic hypoganglionosis associated with CMV colitis in an immunocompetent patient.
CASE SUMMARY A 48-year-old woman with no underlying disease was admitted to our hospital for severe abdominal pain and constipation. Computed tomography of the abdomen showed diffuse dilatation of the small intestine and the entire colon. Initial sigmoidoscopic findings and result of polymerase chain reaction (PCR) for CMV revealed the compatible findings of CMV colitis, the patient was treated with intravenous ganciclovir. After treatment, sigmoidoscopic findings and CMV PCR results improved. However the patient continued to suffered from constipation. Eight months after the initial admission, patient visited the emergency department with severe abdominal pain and imaging revealed aggravation of fecal impaction and bowel dilatation. We performed subtotal colectomy to control patient’s symptom. Histological examination of the resected specimen showed significantly reduced number of mature ganglion cells in the sigmoid colon compared to that in the proximal colon.
CONCLUSION Our case demonstrates that CMV colitis can develop even in patients with no other underlying disease, and that CMV colitis can be one of the causes for developing colonic hypoganglionosis.

Abstract
The enteric nervous system (ENS) is the largest division of the peripheral nervous system and closely resembles components and functions of the central nervous system. Although the central role of the ENS in congenital enteric neuropathic disorders, including Hirschsprung disease and inflammatory and functional bowel diseases, is well acknowledged, its role in systemic diseases is less understood. Evidence of a disordered ENS has accumulated in neurodegenerative diseases ranging from amyotrophic lateral sclerosis, Alzheimer disease and multiple sclerosis to Parkinson disease as well as neurodevelopmental disorders such as autism. The ENS is a key modulator of gut barrier function and a regulator of enteric homeostasis. A 'leaky gut' represents the gateway for bacterial and toxin translocation that might initiate downstream processes. Data indicate that changes in the gut microbiome acting in concert with the individual genetic background can modify the ENS, central nervous system and the immune system, impair barrier function, and contribute to various disorders such as irritable bowel syndrome, inflammatory bowel disease or neurodegeneration. Here, we summarize the current knowledge on the role of the ENS in gastrointestinal and systemic diseases, highlighting its interaction with various key players involved in shaping the phenotypes. Finally, current flaws and pitfalls related to ENS research in addition to future perspectives are also addressed.

Abstract
The gastrointestinal lumen is a rich source of eukaryotic and prokaryotic viruses which, together with bacteria, fungi and other microorganisms comprise the gut microbiota. Pathogenic viruses inhabiting this niche have the potential to induce local as well as systemic complications; among them, the viral ability to disrupt the mucosal barrier is one mechanism associated with the promotion of diarrhea and tissue invasion. This review gathers recent evidence showing the contributing effects of diet, gut microbiota and the enteric nervous system to either support or impair the mucosal barrier in the context of viral attack.

Abstract
Intestinal hypoganglionosis is a rare condition in adults. We report a case of intestinal hypoganglionosis in the mid-distal transverse colon to splenic flexure in a 65-year-old female patient presenting with altered bowel habit and abdominal distension, and reviewed the current literature on this topic. Our patient had a medical history of neurofibromatosis type 1. A preoperative computed tomography (CT) scan demonstrated a grossly dilated transverse colon without obstruction. A laparotomy for subtotal colectomy was performed, with histopathology demonstrating intestinal hypoganglionosis.

Abstract
RATIONALE Intestinal hypoganglionosis most commonly presents in infancy or childhood, with only a few cases reported in adults. Those are mainly diagnosed after elective surgery for long-standing constipation and megacolon. PATIENT CONCERNS We report a case of a 48-year-old female from China who presented with symptoms of discontinuation of bowel movements for 2 months. A hard, round mass could be felt in her right lower abdomen. DIAGNOSIS The following examination methods diagnosed acquired segmental sigmoid hypoganglionosis. An abdominal computed tomography revealed a dilatation of the colon and suspicious wall thickening of the sigmoid colon. Anorectal manometry revealed relaxation of the anal sphincter. Histological examination revealed lower numbers and the degeneration of ganglion cells. INTERVENTIONS Sigmoidectomy and transverse colostomy. OUTCOMES The patient recovered well from surgery. Three months after the surgery, barium enema revealed a recovery in colorectal dilatation. LESSONS This case could help raise awareness of acquired segmental hypoganglionosis. Resection of TZ and enterostomy presents an effective remission strategy for patients at risk of anastomotic leakage due to poor intestinal conditions.

Abstract
Acquired isolated hypoganglionosis is a rare intestinal neurological disease, which presents in adulthood with the clinical symptoms of chronic constipation. A 39-year-old man underwent laparoscopic low anterior resection and covering ileostomy for locally advanced-rectal cancer. A 6-month course of postoperative adjuvant chemotherapy was completed, followed by closure of the ileostoma. After the closure, he developed severe colitis which required 1-month of hospitalization. Mucosal erosions and pseudo-membrane formation were evident on colonoscopy and severe mucosal damage characterized by infiltration of inflammatory cells and crypt degeneration were pathologically confirmed. Even after the remission of the colitis, he suffered from severe constipation and distention. At 4 years after the stoma closure, he decided to undergo laparoscopic total colectomy. Histopathologically, the nerve fibers and ganglion cells became gradually scarcer from the non-dilated to dilated regions. Immunohistochemical staining examination confirmed that the ganglion cells gradually decreased and became degenerated from the normal to dilated region, thereby arriving at the final diagnosis of isolated hypoganglionosis. The patient recovered without any complications and there has been no evidence of any relapse of the symptoms. We present a case of acquired isolated hypoganglionosis-related megacolon, which required laparoscopic total colectomy, due to severe enterocolitis following stoma closure.

Abstract
BACKGROUND Hypoganglionosis is a rare condition that most often presents with abnormal gastrointestinal transit and usually arises in early childhood or adolescence. Two types have been described (Type I and Type II). The adult-onset form (acquired hypoganglionosis) is extremely uncommon and is thought to arise due to cellular remodelling as a result of chronic inflammation. It differs from Hirschprung’s disease in that there is a reduction in ganglion cells in the colonic neural plexuses as opposed to being completely absent.
CASE SUMMARY A 31 year-old male presented to hospital with recurrent abdominal pain and vomiting over thirteen months. Abdominal computed tomography scans demonstrated thickening and stranding affecting the transverse, descending and sigmoid colon. Endoscopic appearances were non-specific but confirmed a mixed picture of mucosal inflammation and necrosis in various stages of healing. Numerous investigations were performed to elucidate an underlying aetiology but neither an infective nor ischaemic cause could be proven. Biopsy features were not typical of inflammatory bowel disease. Due to persistence of his symptoms and failure of medical management, a segmental colectomy was performed. Histological examination of the specimen revealed an unexpected finding of segmental hypoganglionosis. Complete surgical excision of the diseased segment of colon was curative and since his operation the patient has had no recurrence of symptoms requiring hospitalisation.
CONCLUSION Our case serves to raise awareness of acquired hypoganglionosis as a rare condition that can result from chronic colitis.

BACKGROUND Reoperations in Hirschsprung disease (HD) may be required due to pathological problems. We conducted this retrospective study to determine the incidence and outcomes of innervation disorders among HD patients following pull-through operation. MATERIALS AND METHODS We retrospectively reviewed the data of patients who underwent pull-through procedure from 2005 to 2017. Only patients who underwent reoperation due to histological disorders were analyzed. Patients with mechanical obstruction that caused recurrent constipation were excluded. RESULTS There were 836 patients who got treated for HD in our department during the study period, and of these, 72 (8.6%) had redo operation. Thirty-one out of the 72 patients (43.1%) showed abnormal histological findings on full-thickness biopsies. Primary operations included totally transanal endorectal pull-through (18), laparoscopic-assisted Duhamel (5) and Soave (8) techniques. The full-thickness biopsies before the reoperation showed aganglionosis (n = 8, 1 was residual resulted from false-positive intraoperative frozen sections and 7 were acquired aganglionosis), transition-zone (3), intestinal neuronal dysplasia B (IND B, n = 15), and hypoganglionosis (5). The final diagnoses according to the resection specimens of the initial and second operations were HD (11), Hirschsprung-associated IND B (15), and Hirschsprung-associated hypoganglionosis (5). Reoperation consisted of laparoscopic-assisted Duhamel (14) and Soave procedures (17). In these patients, 77.4% had excellent/good bowel function, 16.1% were fair, and 6.5% were poor. CONCLUSIONS Innervation disorders are still the underlying causes of recurrent constipation in almost half of all HD patients requiring redo pull-through operation. Most patients have a satisfactory outcome after redoing laparoscopic-assisted Duhamel or Soave operation.

Abstract
OBJECTIVES To review infectious diseases that may cause autonomic dysfunction. METHODS Review of published papers indexed in medline/embase. RESULTS Autonomic dysfunction has been reported in retrovirus (human immunodeficiency virus (HIV), human T-lymphotropic virus), herpes viruses, flavivirus, enterovirus 71 and lyssavirus infections. Autonomic dysfunction is relatively common in HIV-infected patients and heart rate variability is reduced even in early stages of infection. Orthostatic hypotension, urinary dysfunction and hypohidrosis have been described in tropical spastic paraparesis patients. Varicella zoster reactivation from autonomic ganglia may be involved in visceral disease and chronic intestinal pseudo-obstruction. Autonomic and peripheral nervous system dysfunction may happen in acute tick-borne encephalitis virus infections. Hydrophobia, hypersalivation, dyspnea, photophobia, and piloerection are frequently observed in human rabies. Autonomic dysfunction and vagal denervation is common in Chagas disease. Neuronal depopulation occurs mainly in chagasic heart disease and myenteric plexus, and megacolon, megaesophagus and cardiomyopathy are common complications in the chronic stage of Chagas disease. Parasympathetic autonomic dysfunction precedes left ventricle systolic dysfunction in Chagas disease. A high prevalence of subclinical autonomic neuropathy in leprosy patients has been reported, and autonomic nerve dysfunction may be an early manifestation of the disease. Autonomic dysfunction features in leprosy include anhidrosis, impaired sweating function, localised alopecia ,and reduced heart rate variability. Urinary retention and intestinal pseudo-obstruction have been described in Lyme disease. Diphtheritic polyneuropathy, tetanus and botulism are examples of bacterial infections releasing toxins that affect the autonomic nervous system. CONCLUSIONS Autonomic dysfunction may be responsible for additional morbidity in some infectious diseases.

Immunostaining for Hu C/D and CD56 is useful for a definitive histopathological diagnosis of congenital and acquired isolated hypoganglionosis. Virchows Arch 2017; 470:679-685.

Abstract
Isolated hypoganglionosis (IHG) has been proposed as a distinct entity with two subtypes: congenital IHG (CIHG) and acquired IHG (AIHG). However, due to the rarity of the disease and the lack of defining histological criteria, the concept of IHG is not widely accepted. We studied paraffin-embedded intestinal specimens from 79 patients diagnosed with Hirschsprung's disease (HD) (n = 49), CIHG (n = 25), and AIHG (n = 5) collected between January 1996 and December 2015. Histopathological diagnosis of HD, CIHG, and AIHG was confirmed by hematoxylin and eosin staining and immunohistochemical staining using Hu C/D and CD56. We evaluated (immuno)histopathological findings, counted the number of ganglion cells, and measured the size of Auerbach's plexus. Hu C/D labeled neuronal cell bodies, whereas CD56 was detected in all neuronal components. In HD, all ganglion cells in Auerbach's plexus in the normoganglionic segment (NGS) were immunoreactive for Hu C/D, whereas in the aganglionic segment (AGS), these were replaced by CD56-positive extrinsic nerve fibers and bundles. The number of ganglion cells in AIHG and CIHG was significantly lower than in the NGS of HD (p < 0.05). Auerbach's plexus was significantly smaller in CIHG (p < 0.05) but in AIHG equivalent to the NGS in HD. In summary, immunostaining for Hu C/D and CD56 is useful for definitive histopathological diagnosis of IHG.

Abstract
Intestinal function is primarily controlled by an intrinsic nervous system of the bowel called the enteric nervous system (ENS). The cells of the ENS are neural crest derivatives that migrate into and through the bowel during early stages of organogenesis before differentiating into a wide variety of neurons and glia. Although genetic factors critically underlie ENS development, it is now clear that many non-genetic factors may influence the number of enteric neurons, types of enteric neurons, and ratio of neurons to glia. These non-genetic influences include dietary nutrients and medicines that may impact ENS structure and function before or after birth. This review summarizes current data about gene-environment interactions that affect ENS development and suggests that these factors may contribute to human intestinal motility disorders like Hirschsprung disease or irritable bowel syndrome.

Abstract
The enteric nervous system (ENS) is large, complex and uniquely able to orchestrate gastrointestinal behaviour independently of the central nervous system (CNS). An intact ENS is essential for life and ENS dysfunction is often linked to digestive disorders. The part the ENS plays in neurological disorders, as a portal or participant, has also become increasingly evident. ENS structure and neurochemistry resemble that of the CNS, therefore pathogenic mechanisms that give rise to CNS disorders might also lead to ENS dysfunction, and nerves that interconnect the ENS and CNS can be conduits for disease spread. We review evidence for ENS dysfunction in the aetiopathogenesis of autism spectrum disorder, amyotrophic lateral sclerosis, transmissible spongiform encephalopathies, Parkinson disease and Alzheimer disease. Animal models suggest that common pathophysiological mechanisms account for the frequency of gastrointestinal comorbidity in these conditions. Moreover, the neurotropic pathogen, varicella zoster virus (VZV), unexpectedly establishes latency in enteric and other autonomic neurons that do not innervate skin. VZV reactivation in these neurons produces no rash and is therefore a clandestine cause of gastrointestinal disease, meningitis and strokes. The gut-brain alliance has raised consciousness as a contributor to health, but a gut-brain axis that contributes to disease merits equal attention.

Abstract
Latent wild-type (WT) and vaccine (vOka) varicella zoster virus (VZV) are found in the human enteric nervous system (ENS). VZV also infects guinea pig enteric neurons in vitro, establishes latency and can be reactivated. We therefore determined whether lymphocytes infected in vitro with VZV secrete infectious virions and can transfer infection in vivo to the ENS of recipient guinea pigs. T lymphocytes (CD3-immunoreactive) were preferentially infected following co-culture of guinea pig or human peripheral blood mononuclear cells with VZV-infected HELF. VZV proliferated in the infected T cells and expressed immediate early and late VZV genes. Electron microscopy confirmed that VZV-infected T cells produced encapsulated virions. Extracellular virus, however, was pleomorphic, suggesting degradation occurred prior to release, which was confirmed by the failure of VZV-infected T cells to secrete infectious virions. Intravenous injection of WT- or vOka-infected PBMCs, nevertheless, transmitted VZV to recipient animals (guinea pig > human lymphocytes). Two days post-inoculation, lung and liver, but not gut, contained DNA and transcripts encoding ORFs 4, 40, 66 and 67. Twenty-eight days after infection, gut contained DNA and transcripts encoding ORFs 4 and 66 but neither DNA nor transcripts could any longer be found in lung or liver. In situ hybridization revealed VZV DNA in enteric neurons, which also expressed ORF63p (but not ORF68p) immunoreactivity. Observations suggest that VZV infects T cells, which can transfer VZV to and establish latency in enteric neurons in vivo. Guinea pigs may be useful for studies of VZV pathogenesis in the ENS.

Abstract
AIM: To determine long-term outcomes of surgical treatments for patients with constipation and features of colonic pseudo-obstruction.
METHODS: Consecutive 42 patients who underwent surgery for chronic constipation within the last 13 years were prospectively collected. We identified a subgroup with colonic pseudo-obstruction (CPO) features, with dilatation of the colon proximal to the narrowed transitional zone, in contrast to typical slow-transit constipation (STC), without any dilated colonic segments. The outcomes of surgical treatments for chronic constipation with features of CPO were analyzed and compared with outcomes for STC.
RESULTS: Of the 42 patients who underwent surgery for constipation, 33 patients had CPO with dilatation of the colon proximal to the narrowed transitional zone. There were 16 males and 17 females with a mean age of 51.2 ± 16.1 years. All had symptoms of chronic intestinal obstruction, including abdominal distension, pain, nausea, or vomiting, and the mean duration of symptoms was 67 mo (range: 6-252 mo). Preoperative defecation frequency was 1.5 ± 0.6 times/wk (range: 1-2 times/wk). Thirty-two patients underwent total colectomy, and one patient underwent diverting transverse colostomy. There was no surgery-related mortality. Postoperative histologic examination showed hypoganglionosis or agangliosis in 23 patients and hypoganglionosis combined with visceral neuropathy or myopathy in 10 patients. In contrast, histology of STC group revealed intestinal neuronal dysplasia type B (n = 6) and visceral myopathy (n = 3). Early postoperative complications developed in six patients with CPO; wound infection (n = 3), paralytic ileus (n = 2), and intraabdominal abscess (n = 1). Defecation frequencies 3 mo after surgery improved to 4.2 ± 3.2 times/d (range: 1-15 times/d). Long-term follow-up (median: 39.7 mo) was available in 32 patients; all patients had improvements in constipation symptoms, but two patients needed intermittent medication for management of diarrhea. All 32 patients had distinct improvements in constipation symptoms (with a mean bowel frequency of 3.3 ± 1.3 times/d), social activities, and body mass index (20.5 kg/m2 to 22.1 kg/m2) and were satisfied with the results of their surgical treatment. In comparison with nine patients who underwent colectomy for STC without colon dilatation, those in the CPO group had a lower incidence of small bowel obstructions (0% vs 55.6%, P < 0.01) and less difficulty with long-distance travel (6.7% vs 66.7%, P = 0.007) on long-term follow-up.
CONCLUSION: Chronic constipation patients with features of CPO caused by narrowed transitional zone in the left colon had favorable outcomes after total colectomy.

Abstract
There are subsets of chronic constipation patients showing features of colonic pseudo-obstruction (CPO) with distinct transitional zone (TZ). We intended to analyze the clinicopathologic characteristics and surgical outcomes of these patients. Twenty-five consecutive patients who underwent surgery for constipation over the 9-year period were analyzed. TZ (+) group was defined as patients showing symptoms or signs of large bowel obstruction with dilated proximal and collapsed distal colon around the TZ at the time of operation, but without any evidence of mechanical causes of obstruction. Nineteen (76%) patients had features of CPO with TZ. All TZs were located in the left colon. Pathologically, segmental hypoganglionosis was identified at the TZ in all TZ (+) patients. On the other hand, pathologic diagnosis was intestinal neuronal dysplasia type B in the remaining six (24%) patients having a uniform colon diameter without demonstrable dilatations (TZ (-) group). Among TZ (+) patients, 17 (90%) underwent total colectomy with ileorectal anastomosis and two (10%) underwent enterostomy. Long-term follow-up (median 56 months) showed no recurrence of constipation in this group of patients. All six TZ (-) patients underwent total colectomy with ileorectal anastomosis and two (33%) of them had persistent symptoms of constipation on long-term follow-up (median 60 months). In a subset of adult constipation patients presenting with features of CPO with TZ, segmental hypoganglionosis was the final pathologic diagnosis. Constipation patients with features of CPO with distinct TZ in the left colon are expected to benefit from surgical intervention.

Abstract
BACKGROUND The role of neural regulation in expression and function of intestinal hexose transporters is unknown. The aim of this study is to determine the role of intestinal innervation in gene expression and function of the membrane hexose transporters, SGLT1, GLUT2, and GLUT5 in the enterocyte. We hypothesize that denervation of the small intestine decreases expression of hexose transporters, which leads to decreased glucose absorption. METHODS Six groups of Lewis rats were studied (n = 6 each) as follows: control, 1 week after sham laparotomy, 1 and 8 weeks after syngeneic (no immune rejection) orthotopic small-bowel transplantation (SBT) (SBT1 and SBT8) to induce complete extrinsic denervation, and 1 and 8 weeks after selective disruption of intrinsic neural continuity to jejunoileum by gut transection and reanastomosis (T/A1 and T/A8). All tissue was harvested between 8 AM and 10 AM. In duodenum, jejunum, and ileum, mucosal messenger RNA (mRNA) levels were quantitated by real-time polymerase chain reaction (PCR), protein by Western blotting, and transporter-mediated glucose absorption using the everted sleeve technique. RESULTS Across the 6 groups, the relative gene expression of hexose transporter mRNA and protein levels were unchanged, and no difference in transporter-mediated glucose uptake was evident in any region. The glucose transporter affinity (K(m)) and functional transporter levels (V(max)) calculated for duodenum and jejunum showed no difference among the 6 groups. CONCLUSION Baseline regulation of hexose transporter function is not mediated tonically by intrinsic or extrinsic neural continuity to the jejunoileum.

Abstract
The aim of the present study was to evaluate the expression of innate immunity receptors belonging to the Toll-like family in the neural plexuses of the different tracts of murine intestine, of the human ileum, and in lower dorsal root ganglia (DRGs) from where extrinsic afferents to these plexuses originate. Results obtained by immunohistochemistry and immunofluorescence on paraffin-embedded tissue and whole-mount preparations show that Toll-like receptors (TLRs) -3 and -7, recognizing viral RNA, and TLR4, recognizing lipopolysaccharide (membrane component of Gram-negative bacteria), are expressed in the myenteric and submucous plexuses of murine intestine and human ileum, and in DRGs primary sensory neurons. They also show that TLR4 immunostaining is stronger in murine distal large bowel. In murine tissue, expression of TLRs was present in both neurons and glial cells. These observations indicate that the enteric neural network might be directly activated by bacterial and viral components and is therefore more in the forefront than previously envisaged in defense responses of the intestinal wall and in the cross-talk with intestinal microbiota. They also highlight the presence of a peripheral neural network that by way of hardwired neurotransmission could potentially convey to the central nervous system specific information on our microbial counterpart and invading or potentially invading pathogens.

Abstract
AIM Hypoganglionosis has been associated with fewer intestinal ganglion cells. However, current reports questioned the validity of this clinical entity. The aim of this study is to demonstrate the existence of hypoganglionosis. MATERIALS AND METHODS We have experienced 24 cases of functional intestinal obstruction with abnormalities of the intestinal ganglia. A precise histological examination was performed using quantitative morphometric studies. These results were compared with age-matched controls (n = 13). RESULTS Based on histological examination, disorders in the ganglion cells could be classified into 3 categories: immaturity of ganglia (n = 13), congenital hypoganglionosis (n = 7), and acquired hypoganglionosis (n = 4). In congenital hypoganglionosis, the number as well as the size of ganglion cells are small at birth. The size of ganglion cells tends to increase over time, but their numbers do not increase; as a result, the symptoms of dysmotility do not improve. On the other hand, acquired hypoganglionosis is late onset and characterized as a degeneration of ganglion cells and gliosis histologically. After performing a resection of the affected bowel, the prognosis is usually good. CONCLUSION Congenital and acquired hypoganglionosis are 2 distinct entities. The histological findings as well as the clinical characteristics of these 2 types of hypoganglionosis are different.
