Te on the dissociation of botulinum neurotoxin type A complexes, 555–65, Copyright 2011, with permission from Elsevier. In contrast, the physical term difusion indicates the passive movement of botulinum toxin along a concentra- tion gradient within a fuid. This suggests that the complex with the high molecular weight of 900 kD would have a reduced tendency to leave the mus- cle compared with the markedly smaller non-complexed botulinum toxin, and one would expect a lower rate of of-target efects.

Due to this fibrosis and transverse disposition single or multiple strictures of the ileum are not infrequent purchase ampicillin 250mg free shipping antibiotic xifaxan colitis. Barium meal examination fails to detect any abnormality in the lower ileum as the meal passes quickly through this segment due to hypermotility of the affected segment of the ileum cheap ampicillin 250mg visa antibiotic resistance for dummies.

Difference between hyperplastic ileocaecal tuberculosis and ulcerative tuberculosis are as follows :— Hyperplastic ileo-caecal tuberculosis Ulcerative tuberculosis 1.

It is almost always caused by human strain of though in eastern countries human strain may tubercle bacillus. It occurs in patients with low resistance so cas­ immunity against tuberculosis, that is why the eation and breakdown of tissues are quite co­ response is excess fibrous tissue formation. Usually longer part of the terminal ileum is af­ nal 2 inches of ileum and caecum are affected. Barium meal X-ray is not very suggestive as tant investigation and is diagnostic in majority the barium meal passes quickly through the af­ of cases. Chest X-ray often reveals pulmonary tubercu­ losis as this condition is usually secondary to pulmonary tuberculosis. Stool examination is important as it often con­ sometimes it may contain mucus or even blood tains pus, occult blood and even tubercle bac­ illi. Gradually it was recognised that the disease, though most frequent in the terminal ileum, may affect any part of the intestine and hence the term ‘regional ileitis’ is used. It is now universally accepted that the disease also involves colon, infact it may involve any portion of the G. Two commonest sites which are involved, are the terminal ileum and the anal canal. The particular predisposing factors at these sites are not known with certainty, but could be related to the distribution of excessive lymphoid tissue at these sites or to relative stasis of the bowel contents that could occur in these sites. Cell-mediated immune function seems to be defective in patients with Crohn’s disease. Presence of granulomas and systemic manifestations such as elevation of gamma globulin, erythema nodosum, iritis, eczema etc. Moreover favourable response to corticosteroids and azathioprine also supports this theory. Above all, Crohn’s statement that ‘the actual aetiology is completely unknown’ is still very much true even today. Remainders are seen with ileal disease alone or more proximal small bowel involvement. It must be remembered that though Crohn’s disease is uncommon in oesophagus, stomach and duodenum, anal lesions are quite common. Diseased segments are dull purple-red thickened two or three times normal diameter and covered with strands and patches of thick greyish white exudate. The lumen becomes narrow and the diseased portion of the bowel is thickened by fibrosis, oedema and cellular infiltration. Mesenteric fat tends to grow over the serosa so that it nearly encompasses the bowel. The thick mesentery nursing and draining the diseased bowel contains numerous enlarged lymph nodes. Due to this intense serosal reaction affected loops adhere to the neighbouring structures. Abscesses develop in between the loops and fistulas may originate with the diseased bowei to penetrate into any organ within the abdominal cavity (internal fistula) or may open outside on the abdominal wall (external fistula). The most characteristic feature is that the segments of diseased bowel are separated by apparently normal bowel to form characteristic ‘skip lesions’. The mucosal surface may vary from grossly normal to slightly oedematous and hyperaemic. Long ‘snail-track’ ulcers may be produced from coalescence of the previous ulcers. These transverse ulcers intensify ‘cobblestone’ appearance of the mucosa as these ulcers intervene between the elevated mucosa caused by submucosal thickening. These ulcers penetrate deep into the muscle layers of the gut distinguishing Crohn’s disease from other inflammatory diseases of the bowel such as ulcerative colitis or ischaemic colitis. Infection gains access to the muscle layers through these ulcers and transmural inflammatory reaction sets in. This gives rise to characteristic thickening of the wall of the gut and later fibrotic stenosis. It is the ulceration penetrating through the muscle to the serosal layer of the gut that is responsible for the complications of perforation, abscess and fistula. Fissures may develop from the mucosal ulcers and extend a variable distance into the bowel wall. The anal lesions consist of fissures, fistulas, perianal abscesses and/or spreading superficial ulcerations. Mucosa is essentially normal except for an increase in the proportion of goblet cells. In the intermediate p/iasethickening of the bowel is more attributable to fibrosis of submucosa and subserosa. Small focal ulcers that rarely penetrate the muscularis mucosa develop numerous in the mucosa. The lamina propria is infiltrated with lymphocytes, plasma cells and variable number of eosinophils. In the later stage, in the submucosa, the extensive fibrosis is accompanied by diffuse infiltration of mononuclear cells and prominent hypertrophy and hyperplasia of lymphoid follicles. They resemble the epithelioid giant cell granulomas of tuberculosis but do not caseate and do not contain tubercle bacilli. There is midabdominal or right lower quadrant pain, low grade fever, leucocytosis, often nausea and vomiting and occasionally diarrhoea. Diagnosis is extremely difficult, but probably diarrhoea from the very beginning of the disease gives a clue to distinguish this condition from acute appendicitis where constipation is more common in the early stage. Very rarely there can be free perforation of the small intestine resulting in a local or diffuse peritonitis. Similarly in colon there may be toxic megacolon, but is much less common than in ulcerative colitis. This is due to partial obstruction of the lumen and increase in motility proximal to the site of obstruction. The frequency of stool is not so great as compared to ulcerative colitis and the stools rarely contain mucus, pus or blood as in ulcerative colitis. Frothy and foul smelling stools characteristic of steatorrhoea represent an advance stage of illness. Fever can reflect the development of intramural or abdominal abscesses or may be a systemic sign produced by unknown toxins. Malnutrition manifested by weight loss, anaemia, hypoproteinaemia and vitamins and mineral deficiencies is quite common.

The tumours which are above the reach of sigmoidoscopy generic 500mg ampicillin amex antibiotic quick reference guide, barium enema is the diagnostic tool available discount 500 mg ampicillin with visa antibiotics for genital acne. All polypoid lesions greater than 1 cm diameter should be removed totally and submitted for histologic examination buy ampicillin 500 mg on-line antibiotic resistance vaccines, (ii) Large tumours with invasive malignancy located above 7 cheap ampicillin 250 mg visa antimicrobial zinc gel. If invasive malignancy is detected, immediate abdominoperineal resection should be carried out. It is always advisable to do follow-up proctoscopy at regular intervals, as recurrence is common even though the lesion is histologically benign. Carcinoma of the colorectuni will develop in essentially 100% of patients with familial polyposis unless treated or death from another cause supervenes. These usually start at the age of about 13 years in the distal segments ofthe colon and rectum. Though potentiality of single polyp to develop into cancer is negligible, yet conglomeration of thousands of polyps increase potentiality to transform into carcinoma to a great extent. The smallproduce prominent symptoms so that the disease can be tumours are early adenomatous polyps. The symptoms may be absent or slight intermittent abdominal discomfort may be the only symptom present. Passage of loose stool, blood-stained stool with mucus and frequent bouts of abdominal pain are quite common. Occasionally large polyps may prolapse through the anus or cause intestinal obstruction by initiating intussusception. Any lesion, particularly in the distal colon and rectum, suspected to be malignant should also be biopsied. This is the only way to get rid of all polyps and discard any chance of malignant transformation. To avoid ileostomy some surgeons would prefer to do a subtotal colectomy with an ileorectal anastomosis. There remains a chance of developing cancer in the retained rectum, which is claimed as 5% in 5 years. Obviously regular follow-up proctoscopy should be performed to assess such condition ill early stage. There are also reports of spontaneous regression of rectal polyps after ileoproctostomy. So if close follow-up is performed this procedure can be adopted in patients who have no polyp in the rectum. In this technique the neoplasia-borne rectal mucosa is removed and the ileum is anastomosed with the anal canal through the rectum. Multiple polyposis is not similar as familiar polyposis coli in the sense that (i) polyps are also present in the small bowel (duodenum, jejunum and ileum), (ii) polyps do not appear before the age of 30 or even 40 years and (iii) colorectal cancer is found in */ rd of cases. There is another syndrome known as Turcot syndrome which includes polyposis coli and central nervous system tumours. The distribution of colorectal cancer is such that rectum is the most affected part, next comes sigmoid colon and after that is the caecum. Ascending, transverse and descending colons are after caecum in order of frequency, while hepatic and splenic flexures are the last to be involved by this disease. These are (i) villous adenoma, (ii) familial polyposis, (iii) Gardner’s syndrome and (iv) chronic ulcerative colitis. Those who eat a diet of raw fruits and vegetables and unrefined grains and produce large bulky stools with a rapid transit time are much less affected by this cancer, polyps and diverticulosis. The rate of colonic cancer is directly proportional to the level of animal fat, particularly beef, in the diet. High fat diet changes the composition of intestinal flora, with an increase in the species able to chemically alterprimary bile acids and sterols. Primary bile acids are converted to secondary bile acids such as deoxycholic and lithocholic acids, a step in the formation of carcinogenic polycyclic aromatic compounds. Absence of gallbladder will lead to continuous flow of bile salts and prolonged exposure of bile acids to intestinal flora which will change the primary bile acid to secondary bile acids. But gradually there is a shift to the right colon and now only 40% are claimed to be within the reach of sigmoidoscope and nearing 30% are seen in the caecum and ascending colon. The annular variety which is more often seen in the sigmoid colon and rectum carries a relatively better prognosis, not because the growth is of low-grade malignancy, but because it gives rise to early obstructive symptoms and is extirpated early before it metastasises. In well differentiated tumours the cells are grouped inacinar clusters simulatingnormal glands. In poorly differentia ted or anaplastic tumours, cells are dispersed in irregularsheetsor cords with no suggestion of gland formation. Malignant cells are characterised by pleomorphism, hyperchromatism, large vesicular nuclei of various sizes and shape with frequent mitoses. Broder ’s classification grading system indicates whether the tumour is a well differentiated type or anaplastic type to predict biologic behaviour of the tumour. It first spreads circularly round the intestinal wall and to certain extent longitudinally. So it can cause intestinal obstruction early before penetrating into adjacent structures. Only in case of ulcerative variety there is more penetration into the bowel wall and to the serous coat, ultimately adjacent structures are invaded. Regional lymph node involvement is the most common form of metastasis in colorectal carcinoma. Even when the lesion is confined to the bowel wall, incidence of positive nodes is about 45%. To perform radical excision of colon, the affected lymph nodes should be removed en masse and to perform this, the arteries alongwith the lymph nodes are clamped and a long segment of bowel has to be excised. Lungs and bones are the next common sites and the cells reach there by passage through the liver into the inferior vena cava or by extension of the tumour into the tissues drained by systemic veins. Early sites of involvement are the omentum and rectovesical or rectouterine pouch. Another frequent site is the ovary resulting in large bilateral Krukenberg’s tumour and bilateral oophorectomy may be needed unless there is definite contraindication. Sometimes the patient will complain of above symptoms only and on careful palpation the mass may be discovered, (vi) Severe symptoms such as cachexia, jaundice and hepatomegaly will obviously group this tumour as an advanced one. The patient often states that he is facing difficulty in getting the bowels to move, so he has to take increasing doses of purgatives. Because of drastic purgation and irritation by the scybala above the neoplasm, excessive mucus is secreted and diarrhoea follows. So constipation followed by diarrhoea is a very suggestive symptom, (ii) Pain may be of constant ache, which suggests pericolitis or cramping type due to obstruction, (iii) Palpable lump is often not the growth but impacted faeces above it.
