Пациенты пожилого и старческого возраста в силу физиологических причин и коморбидной патологии имеют высокий риск развития запора. Причиной запора чаще всего являются алиментарные факторы и возраст-ассоциированные заболевания и повреждения толстой кишки (дивертикулярная болезнь, ишемия толстой кишки, ректоцеле, геморрой и другие); метаболические, эндокринные расстройства и неврологические заболевания. Возрастные анатомические, структурные и функциональные изменения пищеварительной системы вносят свой вклад в развитие запоров у пожилых. У пациентов «серебряного возраста» отмечено увеличение длины желудочно-кишечного тракта, прогрессирование атрофических, склеротических изменений слизистой и подслизистой оболочки, снижение количества секреторных клеток, замещение мышечных волокон соединительной тканью и др. Все это способствует замедлению транзита по желудочно-кишечному тракту и нарушению акта дефекации. Образ жизни пожилых людей также может способствовать развитию запора. Низкое содержание в рационе клетчатки, употребление преимущественно термически обработанной пищи, нарушение ритма питания (прием пищи 1-2 раза в день) являются одной из причин возникновения запоров у пожилых, чему способствуют трудности при жевании вследствие стоматологических проблем. Колоноскопия показана всем пациентам пожилого и старческого возраста с запором, а выявление «симптомов тревоги» необходимо проводить при каждом визите пациента. Вне зависимости от причины вторичного запора, все пациенты должны осуществлять ряд мер немедикаментозного характера, включающих изменение образа жизни, диету с включением достаточного количества клетчатки и потребление жидкости. Физические методы лечения могут включать лечебную гимнастику, массаж толстой кишки для стимуляции моторной активности кишечника в определенное время. При неэффективности немедикаментозных мероприятий рекомендуется использование осмотических слабительных, а также средств, увеличивающих объем каловых масс. Высокая эффективность и безопасность псиллиума позволяет рекомендовать его в лечении хронического запора у пожилых пациентов. Elderly and senile patients, due to physiological reasons and comorbid pathology, have a high risk of constipation. The causes of constipation are more often nutritional factors and age-associated diseases and damage to the colon (diverticular disease, colon ischemia, rectocele, hemorrhoids, and others); metabolic, endocrine disorders and neurological diseases. Age-related anatomical, structural and functional changes in the digestive system contribute to the development of constipation in the elderly. In patients of «silver age», there was an increase in the length of the gastrointestinal tract, the progression of atrophic, sclerotic changes in the mucous and submucosa, a decrease in the number of secretory cells, replacement of muscle fibers with connective tissue, etc. All this contributes to the slowing down of transit through the gastrointestinal tract and the violation of the act of defecation. Elderly lifestyles can also contribute to constipation. The low fiber content in the diet, the use of mainly thermally processed food, the violation of the rhythm of the diet (eating 1-2 times a day) are one of the causes of constipation in the elderly, which is facilitated by difficulty in chewing due to dental problems. Colonoscopy is ordered for all elderly and senile patients with constipation, and the identification of «anxiety symptoms» should be carried out at each patient visit. Regardless of the cause of secondary constipation, all patients should take a number of non-pharmacological measures, including lifestyle changes, a diet with adequate fiber, and fluid intake. Physical therapies may include medical gymnastics, colon massage to stimulate bowel movement at specific times. If non-drug measures are ineffective, it is recommended to use osmotic laxatives, as well as agents that increase the volume of feces. Psyllium supplementation is recommended for treatment of chronic constipation in elderly patients due to its high efficacy and safety.

Aim. To estimate dynamics of secretory and motor-evacuational functions of the stomach in patients with type 1 diabetes mellitus and gastrointestinalform of diabetic neuropathy. Materials and methods. 32 patients with DM1 without gastrointestinal pathology allocated to different groups depending on DM duration (gr. 1 lessthan 10 yr, gr. 2 over 10 yr). Vegetative equilibrium was estimated from the Kerdo index, rehabilitative potential from its basic constituent (morphophysiologicalindex). The motor-evacuational function of the stomach was studied with the use of a scintillation gamma-chamber, the gastric secretoryfunction by pH measurements. Results. Half of the patients in gr 2 presented with hypersympathicotony. The frequency of hypertonic form of gastric tone increased with durationof DM while the acid-producing and evacuational functions of the stomach decreased (as estimated by pH-measurement and gastroscintiographyrespectively). The propulsive function most significantly decreased in the pyloric part. The efficacy of rehabilitation of diabetic patients with gastrointestinalform of diabetic neuropathy was much lower than in those with preserved vegetative function of the stomach. Conclusion. Impairment of evacuational function of the stomach and duodenum with DM1 duration may be a cause of unstable blood glucose level.Hypomotor dyskinesia of the upper gastrointestinal tract due to DM1 and deficit of parasympathetic innervation occurs more frequently in patientswith low rehabilitative potential. Functional changes in the gastrointestinal tract of DM1 patients do not depend on the quality of compensation ofmetabolic disorders but correlate (r=-0.39) with DM duration. It is concluded that the gastrointestinal form of diabetic neuropathy impairs rehabilitativepotential of fhe patients.

The detrusor smooth muscle is the main muscle component of the urinary bladder wall. Its ability to contract over a large length interval and to relax determines the bladder function during filling and micturition. These processes are regulated by several external nervous and hormonal control systems, and the detrusor contains multiple receptors and signaling pathways. Functional changes of the detrusor can be found in several clinically important conditions, e.g., lower urinary tract symptoms (LUTS) and bladder outlet obstruction. The aim of this review is to summarize and synthesize basic information and recent advances in the understanding of the properties of the detrusor smooth muscle, its contractile system, cellular signaling, membrane properties, and cellular receptors. Alterations in these systems in pathological conditions of the bladder wall are described, and some areas for future research are suggested.
