2Neurogenic bowel dysfunction in patients with spinal cord injury, myelomeningocele, multiple sclerosis and Parkinson’s disease显示文摘Exciting new features have been described concerning neurogenic bowel dysfunction,including interactions between the central nervous system,the enteric nervous system,axonal injury,neuronal loss,neurotransmission of noxious and non-noxious stimuli,and the fields of gastroenterology and neurology.Patients with spinal cord injury,myelomeningocele,multiple sclerosis and Parkinson's disease present with serious upper and lower bowel dysfunctions characterized by constipation,incontinence,gastrointestinal motor dysfunction and altered visceral sensitivity.Spinal cord injury is associated with severe autonomic dysfunction,and bowel dysfunction is a major physical and psychological burden for these patients.An adult myelomeningocele patient commonly has multiple problems reflecting the multisystemic nature of the disease.Multiple sclerosis is a neurodegenerative disorder in which axonal injury,neuronal loss,and atrophy of the central nervous system can lead to permanent neurological damage and clinical disability.Parkinson's disease is a multisystem disorder involving dopaminergic,noradrenergic,serotoninergic and cholinergic systems,characterizedby motor and non-motor symptoms.Parkinson's disease affects several neuronal structures outside the substantia nigra,among which is the enteric nervous system.Recent reports have shown that the lesions in the enteric nervous system occur in very early stages of the disease,even before the involvement of the central nervous system.This has led to the postulation that the enteric nervous system could be critical in the pathophysiology of Parkinson's disease,as it could represent the point of entry for a putative environmental factor to initiate the pathological process.This review covers the data related to the etiology,epidemiology,clinical expression,pathophysiology,genetic aspects,gastrointestinal motor dysfunction,visceral sensitivity,management,prevention and prognosis of neurogenic bowel dysfunction patients with these neurological diseases.Embryological,morphological and experimental studies on animal models and humans are also taken into account.Richard A Awad 2011World Journal of Gastroenterology2011,17,46:20
3Sclerostin activity plays a key role in the negative effect of glucocorticoid signaling on osteoblast function in mice显示文摘Stress during prenatal development is correlated with detrimental cognitive and behavioral outcomes in offspring. However, the long-term impact of prenatal stress(PS) and disrupted glucocorticoid signaling on bone mass and strength is not understood. In contrast, the detrimental effect of lead(Pb) on skeletal health is well documented. As stress and Pb act on common biological targets via glucocorticoid signaling pathways and co-occur in the environment, this study first sought to assess the combined effect of stress and Pb on bone quality in association with alterations in glucocorticoid signaling. Bone parameters were evaluated using microCT, histomorphometry, and strength determination in 8-month-old male mouse offspring subjected to PS on gestational days 16 and 17, lifetime Pb exposure(100 p.p.m. Pb in drinking water), or to both. Pb reduced trabecular bone mass and, when combined with PS, Pb unmasked an exaggerated decrement in bone mass and tensile strength. Next, to characterize a mechanism of glucocorticoid effect on bone, prednisolone was implanted subcutaneously(controlled-release pellet, 5 mg·kg^(-1) per day) in 5-month-old mice that decreased osteoblastic activity and increased sclerostin and leptin levels. Furthermore, the synthetic glucocorticoid dexamethasone alters the anabolic Wnt signaling pathway. The Wnt pathway inhibitor sclerostin has several glucocorticoid response elements, and dexamethasone administration to osteoblastic cells induces sclerostin expression. Dexamethasone treatment of isolated bone marrow cells decreased bone nodule formation, whereas removal of sclerostin protected against this decrement in mineralization.Collectively, these findings suggest that bone loss associated with steroid-induced osteoporosis is a consequence of sclerostin-mediated restriction of Wnt signaling, which may mechanistically facilitate glucocorticoid toxicity in bone.Eric E Beier Tzong-Jen Sheu Emily A Resseguie Masahiko Takahata Hani A Awad Deborah A Cory-Slechta J Edward Puzas 2017Bone Research2017,5,2:3
4Rectal tone and compliance affected in patients with fecal incontinence after fistulotomy显示文摘AIM: To investigate the anal sphincter and rectal factors that may be involved in fecal incontinence that develops following fistulotomy(FIAF).METHODS: Eleven patients with FIAF were compared with 11 patients with idiopathic fecal incontinence and with 11 asymptomatic healthy subjects(HS). All of the study participants underwent anorectal manometry and a barostat study(rectal sensitivity, tone, compliance and capacity). The mean time since surgery was 28 ± 26 mo. The postoperative continence score was 14 ± 2.5(95%CI: 12.4-15.5, St Mark's fecal incontinence grading system).RESULTS: Compared with the HS, the FIAF patients showed increased rectal tone(42.63 ± 27.69 vs 103.5 ± 51.13, P = 0.002) and less rectal compliance(4.95 ± 3.43 vs 11.77 ± 6.9, P = 0.009). No significant differences were found between the FIAF patients and the HS with respect to the rectal capacity; thresholds for the non-noxious stimuli of first sensation, gas sensation and urge-to-defecate sensation or the noxious stimulus of pain; anal resting pressure or squeeze pressure; or the frequency or percentage of relaxation of the rectoanal inhibitory reflex. No significant differences were found between the FIAF patients and the patients with idiopathic fecal incontinence.CONCLUSION: In patients with FIAF, normal motor anal sphincter function and rectal sensitivity are preserved, but rectal tone and compliance are impaired. The results suggest that FIAF is not due to alterations in rectal sensitivity and that the rectum is more involved than the anal sphincters in the genesis of FIAF.Richard Alexander Awad Santiago Camacho Francisco Flores Evelyn Altamirano Mario Antonio García 2015World Journal of Gastroenterology2015,21,13:3
5In vitro and in vivo effects of ferulic acid on gastrointestinal motility:Inhibition of cisplatin-induced delay in gastric emptying in rats显示文摘AIM: To study the effects of ferulic acid on gastrointe-stinal motility both in vitro and in vivo.METHODS: Ferulic acid induced concentration-dependent stimulation of the basal tone of isolated guinea pig ileum (2-20 μmol/L) and isolated rat fundus (0.05-0.4 mmol/L). RESULTS: Ferulic acid significantly accelerated the gastrointestinal transit and gastric emptying in rats in a dose-dependent manner (50-200 mg/kg, po). Cisplatin (2.5-20 mg/kg, ip) induced a dose-dependent delay in gastric emptying in rats. Pretreatment with ferulic acid dose-dependently, significantly reversed the cisplatin-induced delay in gastric emptying. CONCLUSION: The endogenous prostaglandins (PGs) are involved in mediating the stimulant effects of ferulic acid. This effect of dietary ferulic acid may help improve other accompanying gastrointestinal symptoms such as abdominal discomfort and also may protect against emesis induced by cytotoxic drugs.Osama A Badary Azza S Awad Mohey A Sherief Farid MA Hamada 2006World Journal of Gastroenterology2006,12,33:2
