These muscles are functionally important for artery which supplies blood by mesenteric arterial arcades peristalsis medicine for constipation purchase prasugrel 10mg mastercard. The main functions of the small intestine are digestion and absorption so that ultimately nutrients passing into the 3 symptoms jaw cancer prasugrel 10 mg without a prescription. The submucosa is composed of loose fibrous tissue with bloodstream are utilised by the cells in metabolism medicine 72 discount prasugrel online master card. It contains a gangliated mucosal layer of the small intestine has remarkable capacity plexus medicine 2 cheap prasugrel 10 mg, Meissner’s plexus, having fewer and smaller cells for regeneration and new lining is laid every 3-4 days. It is Intestinal atresia is congenital absence of lumen, most supported externally by thin layer of smooth muscle fibres, commonly affecting the ileum or duodenum. The mucous membrane is thrown into segment has a blind end which is separated from distal folds or plicae which are more in the jejunum and less in the segment freely, or the two segments are joined by a fibrous ileum, thus increasing the absorptive surface enormously. The condition must be recognised early and treated the absorptive surface is further increased by the intestinal surgically, as otherwise it is incompatible with life. Villi are finger-like or leaf-like projections which contain 3 types of cells: Intestinal stenosis is congenital narrowing of the lumen i) Simple columnar cells. Intestinal segment due to the presence of brush border consisting of large above the level of obstruction is dilated and that below it is number of microvilli. These are mucus-secreting cells and are Meckel’s Diverticulum interspersed between the columnar cells. These are scattered in the villi as well as Meckel’s diverticulum is the most common congenital are widely distributed throughout the gastrointestinal tract. It is almost always lined by small cells, on the other hand, require the addition of exogenous intestinal type of epithelium; rarely it may contain islands of reducing substance for staining). These are commonly multiple (diverticulosis), frequently located on the hypothalamus, pituitary and sympathetic ganglia. Intestinal Malrotation the duodenum contains distinctively branched Brunner’s Malrotation is a developmental abnormality of the midgut glands present in the submucosa and going up to muscularis. The deeper layer of the mucosa of the small flexure and the middle of transverse colon). Due to failure of intestine elsewhere contains intestinal glands or crypts of normal rotation of midgut, the following consequences can Lieberkuhn. They are lined by columnar cells, goblet cells, occur: endocrine cells and Paneth cells. B, Resected segment of the small intestine shows an outpouching which on section is seen communicating with the intestinal lumen. The causes of intestinal obstruction can be fibrous adhesions and bands may be without any preceding classified under the following 3 broad groups: peritoneal inflammation and are of congenital origin. It can occur as a result of the complete intestinal obstruction by outside pressure on the following causes: bowel wall. Crohn’s disease) Hernias Congenital stenosis, atresia, imperforate anus Hernia is protrusion of portion of a viscus through an Tumours abnormal opening in the wall of its natural cavity. Meconium in mucoviscidosis External hernia is the protrusion of the bowel through a Roundworms defect or weakness in the peritoneum. Gallstones, faecoliths, foreign bodies Internal hernia is the term applied for herniation that Ulceration induced by potassium chloride tablets does not present on the external surface. Two major factors involved in the formation of a hernia ii) External compression: are as under: Peritoneal adhesions and bands i) Local weakness which may be congenital. Volvulus ii) Increased intra-abdominal pressure that is produced by Intra-abdominal tumour. Obstruction of the superior mesen Direct when hernia passes medial to the inferior teric artery or its branches may result in infarction causing epigastric artery and it appears through the external paralysis. Thrombosis Indirect when it follows the inguinal canal lateral to the Embolism inferior epigastric artery. When the contents of hernia such as loop of intestine can Out of the various causes listed above, conditions be returned to the abdominal cavity, it is called reducible. Some or due to adhesions in the hernial sac, it is referred to as of these are described below. In either case, the cause of 563 ischaemia is compromised mesenteric circulation, while ischaemic effect is less likely to occur in the stomach, duodenum and rectum due to abundant collateral blood supply. Depending upon the extent and severity of ischaemia, 3 patterns of pathologic lesions can occur (Fig. The ischaemic effect in mural infarction is limited to mucosa, submucosa and superficial muscularis, while mucosal infarction is confined to mucosal layers superficial to muscularis mucosae. Ischaemic colitis, due to chronic colonic ischaemia causing fibrotic narrowing of the affected bowel. When the blood flow in the hernial sac is obstructed, it these pathologic patterns are described below: results in strangulated hernia. Obstruction to the venous drainage and arterial supply may result in infarction or Transmural Infarction gangrene of the affected loop of intestine. The gross and Ischaemic necrosis of the full-thickness of the bowel wall is microscopic appearance of strangulated intestine is the same more common in the small intestine than the large intestine. The common causes of transmural Intussusception infarction of small bowel are as under: i) Mesenteric arterial thrombosis such as due to the following: Intussusception is the telescoping of a segment of intestine Atherosclerosis (most common) into the segment below due to peristalsis. The telescoped Aortic aneurysm segment is called the intussusceptum and lower receiving segment is called the intussuscipiens. The condition occurs Vasospasm more commonly in infants and young children, more often Fibromuscular hyperplasia in the ileocaecal region when the portion of ileum invaginates Invasion by the tumour into the ascending colon without affecting the position of Use of oral contraceptives the ileocaecal valve (Fig. Less common forms are ileo Arteritis of various types ileal and colo-colic intussusception. In the case of adults, the usual Endocarditis (infective and nonbacterial thrombotic) causes are foreign bodies and tumours. Atherosclerotic plaques the main complications of intussusception are intestinal Atrial myxoma obstruction, infarction, gangrene, perforation and peritonitis. The causes are as under: Volvulus is the twisting of loop of intestine upon itself through 180° or more. This leads to obstruction of the intestine as well as cutting off of the blood supply to the affected loop. The usual causes are bands and adhesions (congenital or acquired) and long mesenteric attachment. The condition is also referred to as haemorrhagic gastroenteropathy, and in the case of colon as Torsion membranous colitis. Grossly, irrespective of results from conditions causing non-occlusive hypoperfusion the underlying etiology, infarction of the bowel is (compared from transmural infarction which occurs from haemorrhagic (red) type (page 126). In the case of colonic Shock infarction, the distribution area of superior and inferior Cardiac failure mesenteric arteries. The affected areas become dark purple and Intake of drugs causing vasoconstriction. The affected segment of the of demarcation between the infarcted bowel and the bowel is red or purple but without haemorrhage and normal intestine, whereas in venous occlusion the exudation on the serosal surface. The mucosa is infarcted area merges imperceptibly into the normal bowel oedematous at places, sloughed and ulcerated at other (Fig. Microscopically, there is coagulative necrosis and ulcera Microscopically, there is patchy ischaemic necrosis of tion of the mucosa and there are extensive submucosal mucosa, vascular congestion, haemorrhages and haemorrhages. Subsequently, inflammatory cell infiltration superficial muscularis but deeper layer of muscularis and and secondary infection occur, leading to gangrene of the serosa are spared. The condition is clinically characterised by ‘abdominal angina’ in which the patient has acute abdominal pain, Clinically, as in transmural infarction, the features of nausea, vomiting, and sometimes diarrhoea. The disease is abdominal pain, nausea, vomiting and diarrhoea are present, rapidly fatal, with 50-70% mortality rate. With adequate therapy, normal morphology is completely restored in In healed cases, stricture formation, malabsorption and 565 superficial lesions, while deeper lesions may heal by fibrosis short bowel syndrome are the usual complications. Ischaemic having many similarities but the conditions usually have colitis is characterised by chronic segmental colonic distinctive morphological appearance. These 2 conditions are ischaemia followed by chronic inflammation and healing by Crohn’s disease (regional enteritis) and ulcerative colitis: fibrosis and scarring causing obstruction (ischaemic stricture). Ischaemic colitis passes through 3 commonly the segment of terminal ileum and/or colon, stages: infarct, transient ischaemia and ischaemic stricture. External surface of the affected chronic ulcero-inflammatory colitis affecting chiefly the area is fusiform or saccular.

Wagner, the difference between the two is merely gradual and whether Institute for differentiation reflects differing pathogenesis remains unan Pathology, Augsburg swered. Angiodysplasia (Telangiectasia) Epidemiology and Pathogenesis the pathogenesis of angiodysplasia is not entirely clear. Based on pathological studies, Hemorrhage is uncommon (12, 29, 30), and an incidental finding Boley et al. Hypertrophy constricts the points of entry nal bleeding which can be related to substantial morbidity of the veins in the muscle layer, obstructing blood flow. This pathogenesis would also explain why 60–90% of an Angiectasias appear endoscopically as red, circum giodysplasias are found in the right hemicolon (12, 29) where scribed mucosal lesions with a diameter of one mil the wider lumen leads to greater wall tension (according to limeter to a few centimeters ( 14. About half of the Laplace law) and thus increased obstruction of venous the lesions are smaller than 5 mm (31, 38). The number of angiodysplasias per patient can vary and the number of patients with solitary Histology angiodysplasias is about equal to the number of those with multiple lesions (31, 38). One endoscopic study reported Early-stage angiectasias present histologically as dilated, tortu an average of 1. The patient was taking anticoagulants due to mitral valve in an older man undergoing colonoscopy endoprosthesis and had had several gastrointestinal bleeding episodes. Dilated and branchlike capillaries that are clearly related to discretely colon with dilated vein and two dilated as well as a dilated vein are readily vis dilated veins. Clinical picture involves attack in various organs, primarily the brain, lungs, skin, nose, liver and gastrointestinal tract. Lesions can become symptomatic as a result of acute lower Localization can sometimes provide a clue: a circumscribed red gastrointestinal bleeding or due to anemia from chronic bleed patch in the sigmoid colon, for example, is more likely to be an ing. Endoscopic intervention promises little long-term success artifact than a vascular malformation. Despite typical colonoscopic appearances, pathologists in two separate studies observed classic histologi Angiodysplasias can also be detected in the cal appearances (Fig. Prevalence reported in the literature biopsy, causing vessel collapse, or by compression of the vessels ranges between 12–89% (5, 9, 13, 14, 19, 34, 37).

Larger vascular malformations should cases, and can only be controlled by means of a transjugular in not be biopsied, given the risk of bleeding. Patients with portal hypertension often also have dilated veins (varices), primarily in the rectum (Fig. Prevalence re lated to portal hypertension reported in the literature ranges from 8–89% (8–10, 13–15, 34, 37, 40).

Colonic volvulus is a rotation of the colon around an often elongated mesocolon (Fig. The sigmoid colon is most often affected (70%); the cecum and transverse colon are markedly less often affected. Colonic volvulus is a common cause of colonic obstruction in developing countries; elongation of the sigmoid due to the fiber-rich diet is thought to play a role etiopathogenically. In the western world, colonic volvulus is often associated with neurological diseases (Parkinson disease, multiple sclerosis, diseases of the spinal cord) and psychiatric disorders. In psychiatric disorders, it is the administration of psychopharmaceuticals with negative side effects on colonic motility that is blamed.

Nail Embryology Development the development of nail apparatus begins during the eighth week of gestation and is completed by the ffth month (20 weeks) of intrauterine development. The nail bed on the dorsal digit is the frst skin structure to keratinize at around 11 weeks. Keratinization begins distally and then continues over the nail bed toward the proximal nail fold. After 12 weeks, the presumptive nail matrix cells, which will later produce the differentiated nail plate, are found ventral to the proximal nail fold. In the skin, p63 is required for the cross talk between the developing epidermis and dermis. Mucoepithelial dysplasia is a rare autosomal dominant disorder char acterized by ocular and cutaneous involvement. Genetic Diseases Involving the Nail and Other Organs Most of the genodermatoses belong to this group. The radius head is small that can cause limitation in elbow motion or subluxation. Heterochromia of the iris with hyperpigmentation of the papillary margin is a helpful key feature for diagnosis.
