Cervical oesophagus: It extends from cricopharyngeus which is the horizontal part of inferior constrictor muscle antibiotics with penicillin oraminax 1000 mg discount. In lower third it deviates towards the left and continues as abdominal oesophagus infection wisdom tooth extraction cheap oraminax 1000mg mastercard. It is related to antimicrobial spray purchase oraminax 375mg with amex azygos vein antibiotic 100 mg order oraminax 375 mg on-line, thoracic duct (which crosses the oesophagus posteriorly from right to left), aorta, pleura and pericardium. Lower end is 40 cm from the upper incisors (Upper jaw is fixed and so is used as the land mark to measure, but not the lower jaw which is mobile). It lacks serosal layer but is surrounded by a layer of loose fibroareolar adventitia. Bronchoaortic constriction-Located at the level of T4 ­ 25 cm from upper incisor ­ site of endoscopic perforation 3. Diaphragmatic constriction-Occurs where oesophagus traverses the diaphragm (Level of T10) ­ 40 cm from upper incisor Arterial supply of oesophagus By inferior thyroid artery, oesophageal branches of the aorta, gastric arteries and inferior phrenic arteries. Venous drainage of oesophagus By inferior thyroid vein, brachiocephalic vein, left hemiazygos vein, azygos vein, coronary vein, splenic vein and inferior phrenic vein. Veins are longitudinal and they lie in submucosal plane in lower third and in muscular plane above. Lymphatic drainage Lymphatic arrangement in oesophagus is longitudinal and so spread of carcinoma to distant lymph nodes occurs early. Lymph nodes are: ­ Paraoesophageal groups located in the wall of the oesophagus and are cervical, thoracic, paraoesophageal and paracardial nodes. Lateral oesophageal groups receive lymph from para and perioesophageal lymph nodes. At late stage laryngeal carcinoma also can cause dysphagia along with hoarseness of voice. Dysphagia due to problem in oesophageal involuntary phase of swallowing is specified by food getting stuck in the pathway. It is due to disappearance of proximal right 4th aortic arch instead of distal portion. All patients having this anomaly (dysphagia lusoria) have got an aberrant right subclavian artery in a transposed position arising from descending aorta that courses posterior to oesophagus. It is categorised based on their specific subclavian anomaly ­ depends on presence of aneurysm, occlusive disease and compression. Presentations may be dysphagia, chest pain, stridor, wheeze, recurrent respiratory infection (usually presents after the age of 40). Treatment is reconstruction or ligation of aberrant right subclavian artery by sternotomy/by neck approach. Large malignant thyroid or anaplastic thyroid can cause dysphagia with dyspnoea or stridor. Endoscopy shows whitish curd like plaques in the oesophageal mucosa which can not be moved (whereas food particles can be moved). Rare causes­ · Diffuse oesophageal spasm: They are incoordinated contractions of oesophagus causing chest pain or dysphagia. Hypertrophy of circular muscle fibres with very high persistent pressure of 400-500 mm Hg is specific. Treatment is calcium channel blockers, vasodilators, endoscopic dilatation and extended oesophageal surgical myotomy up to the aortic arch (very useful especially for dysphagia; not much for chest pain). Aortic arch anomalies are ­ double arch Evaluation of a Patient with Dysphagia · Proper history. Biopsy from lesions, endotherapy if needed should be carried out (like F/B removal; stricture dilatation; sclerotherapy). A pH less than 4 for more than 4% of total 24 hours period (more than near to one hour in toto in 24 hours) is pathological reflux. Barium swallow · Dysphagia due to motility disorder like achalasia cardia, diffuse oesophageal spasm. Therapeutic · To remove foreign body · To dilate stricture · To place endostents for inoperable carcinoma oesophagus · To inject sclerosants for varices Types 1. Head is extended and head end of the table is tilted upwards, scope is passed behind the epiglottis and cricoid through the cricopharyngeal opening. It shows all layers clearly and distinctly and so invasion can be better made out and operability can be decided.

Immunosuppression: By cyclosporine infection by fingernail purchase 375mg oraminax with visa, azathioprine virus morphology buy oraminax 375 mg lowest price, prednisolone bacteria zinc cheap 375 mg oraminax amex, antithymocytic globulin and antilymphocytic serum 0x0000007b virus oraminax 1000 mg on line. Rejection (Rejection is identified by radioisotope study and percutaneous kidney biopsy). Infection by unusual organisms like cytome galovirus, herpes, pneumocystis carnii, varicella and other bacterial infections, candidial infection. Tissue typing and cross matching are not that necessary and do not influence the results. If the transplantation is done at the same site after doing hepatectomy, it is called as orthotopic liver transplantation. If it is placed in a different site it is called as ectopic or heterotopic liver transplantation. Complications Graft pancreatitis, pancreatic leak, bleeding, urinary infections like cystitis, failure. Islet cell rejection is prevented by covering them with semipermeable membrane which prevents antibodies reaching islet cells but allowing insulin to get secreted. Exocrine function is achieved immediately; endocrine (insulin) function is achieved after few days. Isolated Pancreatic Islet Transplantation Islets of Langerhans are obtained by mechanical disruption of pancreas by injecting collagenase into the pancreatic duct. Hyperacute rejection is due to antibody reaction which occurs within minutes of vascularization of the graft 2. Acute rejection results due to cell mediated immunity, occurring in a few days to first 3 months of transplant. It is common type If there were no obstacles, there would have been no achievements. Here dialysis occurs in a dialysing machine across a semipermeable membrane (usually cellulose membrane). It is technique for the removal of waste product of metabolism, normalisation of plasma electrolytes and removal of plasma water. Insertion of Catheter A rigid plastic catheter is inserted through the abdominal wall into the peritoneal cavity using a trocar through a small cut made in the skin under L/A. Dialysis is done using sterile dialysate solution instilled into and drained out of abdomen. Haemodialysis requires access to circulation which is achieved by creating a fistula between the radial artery. Patient should be given erythropoietin injection 3,000 units twice weekly to prevent repeated blood transfusions. Usually at wrist, radial artery is anastomosed to cephalic vein side-to-side and a created good fistula shows continuous thrill and bruit, with increased venous engorgement along with hyperdynamic circulation. At the ankle, often fistula is created between posterior 295 tibial artery and saphenous vein; in the thigh between femoral artery and long saphenous vein. It causes renal failure, pulmonary oedema, cardiac complications and neurological problems. Monitoring by regular checking of blood urea, serum creatinine and bleeding and clotting time. So heparin is given as 10,000 to 15,000 units loading dose and later 5,000 units as maintenance dose 8th hourly. Brown Spider Bite · It releases sphingomyelinase-D which causes necrosis of the skin and haemolysis. Reasons to control postoperative pain/acute pain · Uncontrolled pain causes tachycardia, hypertension and vasoconstriction · Abdominal (upper abdominal mainly) and thoracic wound pain restricts the respiration causing tachypnoea, altered respiration, coughing, chest infection, pneumonia · Persisting pain causes restricted movements, deep venous thrombosis and its problems, bed sores · Pain delays the recovery and also causes psychological trauma to the patient Management of Pain · Correct the cause like removal of renal stone, cholecystectomy for gallstones. It is better than X-ray mandible lateral view as it highlights proper dentition, inner and outer plates of mandible and joints. Any change in the development or fusion of these arches leads to formation of different types of cleft lip or cleft palate. Proper postoperative management like control of infection, training for sucking, swallowing and speech. For Cleft palate alone involving only soft palate, in one stage surgery is done in 6 months. Cleft palate alone but involving both soft and hard palates ­ soft palate in 6 months; hard palate in 18 months. In combined cleft lip and palate, unilateral or bilateral, in two stages ­ cleft lip and soft palate in 6 months; hard palate in 18 months.

The effect on granulocytes bacteria reproduce by binary fission buy 375 mg oraminax with visa, and especially the platelet count antimicrobial xylitol order 375 mg oraminax otc, is less impressive bacteria ua generic 375mg oraminax otc. Marrow replacement may occur as a result of leukemia antibiotic resistance evolves in bacteria because buy 375 mg oraminax free shipping, solid tumors (especially neuroblastoma), storage diseases, osteopetrosis in infants, and myelofibrosis, which is rare in childhood. In a child with aplastic anemia, pancytopenia evolves as the hematopoietic elements of the bone marrow disappear and the marrow is replaced by fat. The disorder may be induced by drugs such as chloramphenicol and felbamate or by toxins such as benzene. Aplastic anemia also may follow infections, particularly hepatitis and infectious mononucleosis (see Table 150-6). Immunosuppression of hematopoiesis is postulated to be an important mechanism in patients with postinfectious and idiopathic aplastic anemia. Bone marrow aspirate and biopsy are needed for precise diagnosis of the etiology of marrow synthetic failure. Pancytopenia resulting from destruction of cells may be caused by intramedullary destruction of hematopoietic elements (myeloproliferative disorders, deficiencies of folic acid and vitamin B12) or by the peripheral destruction of mature cells. The usual site of peripheral destruction of blood cells is the spleen, although the liver and other parts of the reticuloendothelial system may participate. Hypersplenism may be the result of anatomic causes (portal hypertension or splenic hypertrophy from thalassemia); infections (including malaria); or storage diseases (Gaucher disease, lymphomas, or histiocytosis). Hemolytic Anemias Major Hemoglobinopathies Decision-Making Algorithms Available @ StudentConsult. Because alpha chains are needed for fetal erythropoiesis and production of hemoglobin F (22), alpha chain hemoglobinopathies are present in utero. Single gene deletions produce no disorder (silent carrier state), but can be detected by measuring the rates of and synthesis or by using molecular biologic techniques. Deletion of two genes produces -thalassemia minor with mild or no anemia and microcytosis. In individuals of African origin, the gene deletions occur on different chromosomes (trans), and the disorder is benign. In the Asian population, deletions may occur on the same chromosome (cis), and infants may inherit two number 16 chromosomes lacking three or even four genes. Deletion of all four genes leads to hydrops fetalis, severe intrauterine anemia, and death, unless intrauterine transfusions are administered. Deletion of three genes produces moderate hemolytic anemia with 4 tetramers (Bart hemoglobin) in the fetus and 4 tetramers (hemoglobin H) in older children and adults (see Table 150-5). Beta chain hemoglobinopathies in the United States are more prevalent than alpha chain disorders, possibly because these abnormalities are not symptomatic in utero. The major beta hemoglobinopathies include those that alter hemoglobin function, including hemoglobins S, C, E, and D, and those that alter beta chain production, the -thalassemias. By convention, when describing -thalassemia genes, 0 indicates a thalassemic gene resulting in absent beta chain synthesis, whereas + indicates a thalassemic gene that permits reduced but not absent synthesis of normal chains. Signs and symptoms of thalassemia major result from the combination of chronic hemolytic disease, decreased or absent production of normal hemoglobin A, and ineffective erythropoiesis. Ineffective erythropoiesis causes increased expenditure of energy and expansion of the bone marrow cavities of all bones, leading to osteopenia, pathologic fractures, extramedullary erythropoiesis with resultant hepatosplenomegaly, and an increase in the rate of iron absorption. This suppression permits the bones to heal, decreases metabolic expenditures, increases growth, and limits dietary iron absorption. Splenectomy may reduce the transfusion volume, but it adds to the risk of serious infection. Chelation therapy with deferoxamine or deferasirox should start when laboratory evidence of iron overload (hemochromatosis) is present and before there are clinical signs of iron overload (nonimmune diabetes mellitus, cirrhosis, heart failure, bronzing of the skin, and multiple endocrine abnormalities). Hematopoietic stem cell transplantation in childhood, before organ dysfunction induced by iron overload, has had a high success rate in -thalassemia major and is the treatment of choice. The specific hemoglobin phenotype must be identified because the clinical complications differ in frequency, type, and severity. As the oxygen is extracted and saturation declines, sickling may occur, occluding the microvasculature.

First-generation antihistamines antibiotics joke buy cheap oraminax 625 mg on line, such as diphenhydramine and hydroxyzine antibiotics japan over counter cheap oraminax 625mg line, easily cross the blood-brain barrier infection x ray purchase 375mg oraminax free shipping, with sedation as the most common reported adverse effect antibiotic drops for pink eye discount 625 mg oraminax visa. Use of first-generation antihistamines in children has an adverse effect on cognitive and academic function. In very young children, a paradoxical stimulatory central nervous system effect, resulting in irritability and restlessness, has been noted. Other adverse effects of first-generation antihistamines include anticholinergic effects, such as blurred vision, urinary retention, dry mouth, tachycardia, and constipation. Second-generation antihistamines, such as cetirizine, loratadine, desloratadine, fexofenadine and levocetirizine, are less likely to cross the blood-brain barrier, resulting in less sedation. Azelastine and olopatadine, topical nasal antihistamine sprays, are approved for children older than 5 years and older than 6 years, respectively. Decongestants, taken orally or intranasally, may be used to relieve nasal congestion. Oral medications, such as pseudoephedrine and phenylephrine, are available either alone or in combination with antihistamines. Adverse effects of oral decongestants include insomnia, nervousness, irritability, tachycardia, tremors, and palpitations. For older children participating in sports, oral decongestant use may be restricted. Topical nasal decongestant sprays are effective for immediate relief of nasal obstruction but should be used for less than 5 to 7 days to prevent rebound nasal congestion (rhinitis medicamentosa). Topical ipratropium bromide, an anticholinergic nasal spray, is used primarily for nonallergic rhinitis and rhinitis associated with viral upper respiratory infection. Rhinitis medicamentosa, which is due primarily to overuse of topical nasal decongestants, such as oxymetazoline, phenylephrine, or cocaine, is not a common condition in younger children. Adolescents or young adults may become dependent on these over-the-counter medications. Treatment requires discontinuation of the offending decongestant spray, topical corticosteroids, and, frequently, a short course of oral corticosteroids. The most common anatomic problem seen in young children is obstruction secondary to adenoidal hypertrophy, which can be suspected from symptoms such as mouth breathing, snoring, hyponasal speech, and persistent rhinitis with or without chronic otitis media. Infection of the nasopharynx may be secondary to infected hypertrophied adenoid tissue. Choanal atresia is the most common congenital anomaly of the nose and consists of a bony or membranous septum between the nose and pharynx, either unilateral or bilateral. Bilateral choanal atresia classically presents in neonates as cyclic cyanosis because neonates are preferential nose breathers. Airway obstruction and cyanosis are relieved when the mouth is opened to cry and recurs when the calming infant reattempts to breathe through the nose. Unilateral choanal atresia may go undiagnosed until later in life and presents with symptoms of unilateral nasal obstruction and discharge. Nasal polyps typically appear as bilateral, gray, glistening sacs originating from the ethmoid sinuses and may be associated with clear or purulent nasal discharge. Nasal polyps are rare in children younger than 10 years of age but, if present, warrant evaluation for an underlying disease process, such as cystic fibrosis or primary ciliary dyskinesia. Triad asthma is asthma, aspirin sensitivity, and nasal polyps with chronic or recurrent sinusitis. Foreign bodies are seen more commonly in young children who place food, small toys, stones, or other things in their nose. The index of suspicion should be raised by a history of unilateral, purulent nasal discharge, or foul odor. Treatment modalities include allergen avoidance, pharmacologic therapy, and immunotherapy. Environmental control and steps to minimize allergen exposure, similar to preventive steps for asthma, should be implemented whenever possible (see Table 78-3). Immunotherapy Pharmacotherapy Intranasal corticosteroids are the most potent pharmacologic therapy for treatment of allergic and nonallergic rhinitis.

It is guided manually by compression and release to visualise entire mucosa of small bowel. Blood Supply · Iliocolic, right colic, and middle colic arteries which are branches of superior mesenteric artery supply the colon from caecum to splenic flexure. Lymphatic Drainage · Mucosa contains no lymph channels, so mucosal cancers rarely metastasize. Nerve Supply · Colonic motility is under control of autonomic nervous system; parasympathetic via vagi and pelvic nerves, sympathetic via superior and inferior mesenteric ganglia. Starting from 2 cm above the dentate line, a full thickness rectal biopsy is ideal. Proximal, middle transitional zone of about 1-5 cm length with less, sparse number of ganglions (cone). A still more proximal, hypertrophied dilated segment is actually the normal ganglionic area. After introducing finger into the rectum, child passes toothpaste like stool, with evidence of straining. Constipation, with history of passing stools once in 3-4 days with straining is seen throughout the childhood and also in adolescent period. Common procedures done are: · Modified Duhamel Operation-resection of upper part of the rectum and a part of colon; anastomosis of colon to posterior part of the lower rectum and crushing the spurs to create the rectal pouch. New pouch is created by anterior part of the aganglionic rectum and by ganglionic proximal pulled down colon. Biopsy should be taken from proximal pulled down colon to look for evidence of ganglions. Pulled down proximal colon is sutured to full thickness posterior anal canal just above the dentate line. A strip of muscularis with part of internal sphincter is excised with both muscle layers of the rectum for about 6-10 cm length. Normal colon is brought behind the aganglionic rectum and anastomosed just above the dentate line. Large Intestine 821 Types · Diverticulosis is the initial primary stage of the disease, wherein there is hypertrophy, muscular incoordination leading to increased segmentation and increased intraluminal pressure. At this stage they are asymptomatic, but often get severe spasmodic pain due to colonic segmentation called as painful diverticular disease. It presents with persistent pain in left iliac fossa, fever, loose stool, recurrent constipation, tenderness in right iliac fossa, palpable and thickened sigmoid colon. Pathology There is hypertrophy and thickening of the muscle layer with progressive colonic narrowing and segmentation with raised intraluminal pressure causing pulsion diverticula of only mucosa adjacent to taenia in antimesentric region. Features of Diverticular Disease · In western countries 50% risk to develop diverticular disease for an individual is at the age of 60 yrs. Abscess can be commonly pericolic and pelvic, rarely in buttock and ischiorectal fossa. It causes passage of gas in the urine (pneumaturia) commonly and occasionally feces. Complications of diverticulitis · · · · Perforation and pericolic abscess or peritonitis Progressive stenosis and intestinal obstruction Profuse colonic haemorrhage (17-20%) Fistula formation (5%)-vesicocolic, vaginocolic, enterocolic, colocutaneous. Less fibre diet increases the stool transit time, reduces the stool weight, reduces the bulkiness of stool which increases the intraluminal pressure and muscle hypertrophy. It is more common in individuals with steroid therapy or immunocompromised people. Champagne glass sign-Partial filling of diverticula by barium with stercolith inside- seen in sigmoid diverticula. Once acute stage subsides, barium enema, sigmoidoscopy, colonoscopy can be done (To rule out associated malignancy).
