Histamine2 receptor antagonists like ranitidine decrease acid secretion by inhibiting receptors on gastric parietal cells. The cartilaginous type occurs in distal esophagus and should be differentiated from achalasia and peptic stricture. Children with this type of congenital stenosis have high risk of perforation on endoscopic dilatation and should be treated surgically. Sometimes the ingestion is unwitnessed and the foreign body is completely asymptomatic initially, presenting days to weeks later with complications like abscess, fistula or bleed. Guidelines for management recommend that no foreign body should be left in esophagus for more than 24 hr. Children present with dysphagia, vomiting, weight loss, respiratory symptoms and slow eating whereas toddlers present with coughing and feeding aversion with failure to thrive. The onset is gradual and the average age at diagnosis in children is around 8-9 yr. The esophagus is dilated and the scope passes through the gastroesophageal junction with some gentle pressure. Botulinum toxin injection has been tried but due to short duration of action (a few months) and limited experience, it cannot be recommended as a first line of treatment in children. Diagnosis is based Dysphaga i Dysphagia refers to a sensation of food being hindered in its passage from the mouth to the stomach, i. Odynophagia is painful swallowing and globus is the sensation of a lump in the throat. Dysphagia can be divided into two distinct groups: Oropharyngeal or transfer dysphagia. Presence of drooling, choking, coughing and nasal regurgitation suggests oropharyngeal dysphagia. Disorders involving chewing, oral transfer or pharyngeal phase of swallowing cause this. The main causes are cerebral palsy, bulbar poliomyelitis, muscular dystrophy, brainstem tumors and neuropathy. Etiology of esophageal dysphagia can be broadly divided into two groups: motor causes. Differential Diagnosis and Evaluation the important causes of dysphagia and their evaluation are shown in Table 11. This may be of three types: web or diaphragm, fibromuscular stenosis and stenosis due to cartilaginous tracheobronchial remnants. Eosino philic esophagitis in children and adults: a systematic review and con sensus recommendations for diagnosis and treatment. It is increasingly being recognized as a very common problem in children and is associated with both physical and psychological morbidity and a poor quality of life. The normal stool frequency decreases from 4 or more per day during infancy to once per day at 4 yr of age. Treatment options include the use of elemental formula, elimination diets, or topical corticosteroids. Resolution of the condition with food elimination diets provides evidence that it is a food-antigen driven process. A detailed history and physical examination is the most useful tool for making a diagnosis of constipation. A predominantly liquid and low fiber diet (milk based) is common and contributes to constipation. Examination for features of spina bifida (pigmentation or tuft of hair on lower back), power in lower limbs, perianal sensation, voluntary contraction and tone of anal sphincter and amount and consistency of stool in rectum on per rectal examination are extremely useful for diagnosis. Functional Constipation the increase in intake of low residue diet and sedentary lifestyle is responsible for the increase in functional consti pation in children. Children with functional constipation pass large or hard stools and display stool withholding behavior, charac terized by stiffening of whole bodyand screaming in infants, to walking on tiptoes or tightening of buttocks in older children. Often an acute illness, chang in diet, coercive toilet training or nonavailability of clean toilet leads to nonpassage of stools. The stools become hard and cause pain on passage which leads to association of defecation with pain and withholding. This further increases stool size and hardness with more pain on defecation and a vicious cycle of constipation is initiated. However, an X-ray abdomen may be done to document impaction in select situations. Rectal impaction is responsible for progressive dilatation of the rectum over time and increased threshold volume for rectal sensation and defecation. In young children, this should be done using a nasogastric tube and in hospital under supervision. Intravenous fluids may be required in small children during this period to maintain adequate hydration. The aim of the maintenance phase is to promote regular stooling and prevent reimpaction. Success of this therapy is defined as passage of 1-2 soft stools per day and no soiling. Behavioral training involves establishing a positive routine of sitting on toilet for passing stools after meals regularly (2-3 times per day for 5-10 min) and docu menting all stool passage. A short trial of milk and milk product free diet may be done in cases suspected to have milk allergy.
During this phase antibiotics via iv discount colchicina online mastercard, additional food or fluid is not required as breast milk is nutritionally complete for Box 6 antimicrobial wall panels order colchicina 0.5mg fast delivery. Complementary Feeding After six months of age antibiotics resistance buy colchicina once a day, breast milk alone is not enough to make an infant grow well antibiotic resistance horizontal gene transfer purchase generic colchicina canada. Complementary feeding refers to food which complements breast milk and ensures that the child continues to have enough energy, protein and other nutrients to grow normally. Complementary feeding is started at six months of age, while continuing breastfeeding, Breastfeeding is encouraged up to two years of age in addition to normal food. Key recommendations for breastfeeding and complementary feeding are given in Table 6. Balanced Diet Balanced diet is defined as nutritionally adequate and appropriate intake of food items that provide all the nutrients in required amounts and proper proportions. Even at 9 months, infants need small portions of a mix of food groups to be included in their diet to ensure intakes of all macronutrients and micronutrients. A balanced diet should be consumed by children and adolescents to ensure proper growth and development and to stay healthy and disease free. Cereals, millets and pulses are the major source of most nutrients in Indian diets. Milk provides good quality protein and calcium and hence, is an essential item of our diet. Eggs, flesh foods and fish enhance the quality of diet but Indians are predominantly a vegetarian society and most of our nutrients are derived from cereals, pulse and milk based diets. Oils and nuts are calorie rich foods and are useful in increasing the calorie density. Vegetables and fruits provide protective substances such as vitamins, minerals, fiber and antioxidants.

Contents of some miscellaneous food items have been standardized at All India Institute of Medical Sciences, New Delhi. Most of our traditional foods are bulky and a child cannot eat large quantities at a time. Hence, it is important to give small energy dense feeds at frequent intervals to ensure adequate energy intakes by the child. Energy density of foods given to infants and young children can be increased without increasing the bulk by adding a teaspoon of oil or ghee in every feed. Fat is a concentrated source of energy and increases energy content of food without increasing the bulk. Amylase rich foods such as malted foods reduce the viscosity of the foods and therefore, the child can eat more quantities at a time (malting is germinating whole grain cereal or pulse, drying and then grinding). At 6 months of age, feed should be started with small amount as much as 1-2 teaspoons and the quantity is increased gradually as the child gets older and starts to accept food better. Child should be given time to adapt gradually to larger quantities from teaspoon to tablespoon and then to a katori. By 8 months, most infants can also eat finger foods (snacks that can be eaten by children alone). By 12 months, most children can eat the same types of foods as consumed by the rest of the family. As the child grows older, he should be shifted to more appropriate foods suitable for his age. For small children, the food should not contain particulate matter that may trigger gag reflex or vomiting. An average healthy breastfed infant needs complementary foods 2-3 times per day at 6-8 months of age and 3-4 times per day at 9-24 months. For children 12-24 months of age, additional nutritious snacks such as a piece of fruit should also be offered 1-2 times per day. Snacks are defined as foods eaten between meals that are convenient and easy to prepare. If energy density or amount of food per meal is low, or the child is no longer breastfed, more frequent meals should be provided. Good hygiene and proper food handling should be practiced to prevent children from infections and malnutrition. Simple practices include: (i) washing hands before food preparation and eating, (ii) serving freshly cooked foods (cooked food should not be kept for more than 2-3 hr), (iii) using clean utensils, (iv) covering food properly, and (v) avoiding use of feeding bottles. Feeding the infants and children should be an active, engaging and interactive affair. Parents should actively engage with the child in feeding, making the child sit in the lap and feeding him affectionately in small portions with spoon or with small morsels. Overnutrition is caused by overindulgence or excessive intake of specific nutrients. They are more susceptible to infections, especially sepsis, pneumonia and gastro enteritis. Vitamin deficiencies and deficiencies of minerals and trace elements can also be seen. Malnutrition in young children is conventionally determined through measurement of height, weight, skinfold thickness (or subcutaneous fat) and age. There has been a slow reduction in undernutrition in the country over the years, but we continue to have the highest burden of childhood undernutrition in the world. Low birthweight and undernutrition in childhood are risk factors for diabetes, hypertension and dyslipidemias in adulthood. Wasting on the other hand means low weight-for-height indicating acute undernutrition.

Gastrinomas are diagnosed by finding a markedly elevated serum gastrin level or a prominent increase in gastrin after intravenous secretin administration in a patient with significant gastric acidity virus 7 band order discount colchicina line. Gastrinomas are treated by surgical resection hpv virus 0.5 mg colchicina with visa, if possible antibiotics for uti uk buy cheap colchicina 0.5mg on line, or by reduction of gastric acid production by high-dose proton pump inhibitors bacteria 600 nm buy colchicina online pills, somatostatin analogs, or gastrectomy, if necessary. When surgery is not possible, the same treatment options as discussed earlier for gastrinomas should be considered. Radiation therapy and chemotherapy also may effectively decrease diarrhea and tumor size. Localization procedures and treatments are similar to those described earlier for other pancreatic endocrine tumors. They are classified according to their site of origin as foregut (bronchus, stomach, duodenum, bile ducts, pancreas), midgut (jejunum, ileum, appendix, ascending colon), or hindgut (transverse and descending colon, rectum) carcinoids. They also develop in the ovaries, testes, prostate, kidney, breast, thymus, or skin. Carcinoid syndrome is a humorally mediated disorder consisting of cutaneous flushing (90%), diarrhea (75%), bronchospasm (20%), endocardial fibrosis (33%), right-sided heart valvular lesions, and occasionally pleural, peritoneal, or retroperitoneal fibrosis. Diarrhea and fibrous tissue formation may be caused by serotonin, whereas flushing and wheezing are likely the result of histamine, prostaglandins, or kinins. Solitary intestinal carcinoids secrete mediators into the portal circulation, where they are almost totally Flushing Prostaglandins Wheezing Kinins Histamine Liver Serotonin Diarrhea Figure 54-1. Carcinoid syndrome does not usually occur with these tumors unless the patient has hepatic metastases that impair mediator metabolism or that secrete mediators directly into the hepatic vein. Extraintestinal carcinoids, however, may cause carcinoid syndrome in the absence of metastases because they secrete mediators into venous systems that do not first pass through the liver. These syndromes have been reported mainly with bronchial and pancreatic carcinoid tumors. Carcinoid syndrome results from tumor production of humoral mediators that cause flushing, diarrhea, bronchospasm, and fibrous tissue formation. Most patients with carcinoid syndrome have extensive liver metastases that either impair the metabolic clearance of mediators secreted by the primary tumor or secrete the mediators directly into the hepatic vein. The treatment for carcinoid syndrome is surgery, when possible, or palliation of symptoms by giving medications that reduce secretion of the humoral mediators or antagonize their effects. A carcinoid crisis is best treated with intravenous octreotide and hydrocortisone and avoidance of adrenergic and sympathomimetic agents. Chromogranin A, a sensitive but nonspecific marker of neuroendocrine tumors, is a good alternative test. Mild elevations may occur in many conditions (Table 54-2), but values greater than 31 U/L have 75% sensitivity and 84% specificity for diagnosing carcinoid syndrome. However, approximately 90% of patients with carcinoid syndrome have extensive metastases at the time of diagnosis. The usual goals of therapy are therefore is to provide palliation and to prolong survival. Somatostatin analogs (octreotide, lanreotide) are often highly effective in controlling carcinoid symptoms. Other antiflushing and antidiarrheal strategies can be added if symptom control is inadequate. Other options include hepatic artery embolization, chemoembolization, 90-Y microsphere radioembolization, radiolabeled somatostatin analog therapy, and alpha-interferon. Cytotoxic chemotherapy has produced disappointing results in patients with carcinoid syndrome. Etoposide and cisplatin combination therapy is the most commonly used regimen for poorly differentiated carcinoid tumors. Other agents that have been used with limited success include streptozotocin, 5-fluorouracil, lomustine, doxorubicin, and dacarbazine. Carcinoid crisis is a life-threatening episode of hypotension, flushing, and bronchospasm that is triggered most often by tumor manipulation or anesthesia and less commonly by chemotherapy, hepatic artery embolization, or radionuclide therapy. When these patients undergo surgery or hepatic artery embolization for their tumor or metastases, they should be pretreated with octreotide (Sandostatin), 300 to 500 mg subcutaneously or intravenously, 30 to 60 minutes before the procedure. Anesthesiologists should be specifically notified that the patient has carcinoid syndrome. Patients with carcinoid tumors who have not developed carcinoid syndrome can be tested for their potential to have a carcinoid crisis. A positive response consists of flushing or a blood pressure drop of 20 mm Hg systolic or 10 mm Hg diastolic 45 to 120 minutes after an injection. If this does not abort the episode, additional options include methotrimeprazine (an antiserotonin agent), methoxamine (a direct vasoconstrictor), phentolamine (an alpha-adrenergic blocker), ondansetron (a serotonin receptor antagonist), and glucagon. It is critical to avoid the use of adrenergic and sympathomimetic agents in patients with suspected carcinoid crisis because these drugs can significantly worsen the condition.

However, it may not be sufficiently sensitive to detect thrombosis in vessels such as subclavian veins, superior vena cava or brachiocephalic veins. Echocardiography is useful for vena caval and proximal subclavian vein thrombosis. Chest radiography may reveal findings of pulmonary embolism which include small pleural effusions with wedge shaped pleural-based opacity of pulmonary infarction, but has poor sensitivity. Management Screening tests for hypercoagulable state should ideally be sent prior to initiating anticoagulation. Patients with respiratory distress or neurological problems should be managed in an intensive care unit. Initial therapy requires heparin (unfractionated or low molecular weight) followed by oral warfarin. The duration of therapy depends on the risk of recurrence, which can be assessed by testing for thrombophilic states. The evaluation is best done after 3 months of the event and after stopping anticoagulants. Children with lower limb deep vein thrombosis should be fitted for compression stockings. Recurrent Thrombosis Recurrent thrombosis may occur due to inadequate anticoagulation therapy. The morphology of cells may reveal abnormal size, immaturity, change in nuclear-cytoplasmic ratio, inclusions and abnormal granules. Howell Jolly bodies are found with absent splenic function (asplenia, post splenec tomy) and toxic granulations and shift to the left suggest sepsis. Epstein-Barr virus infection results in large monocytoid cells which can be confused for blasts on peripheral smear. Leukocytosis the onset and duration of illness, history of intake of medications and prior hospitalization may provide a clue to the diagnosis. Monocytosis Monocytes, the circulating tissue macrophage precursors, are important for ingestion and killing of pathogenic bacteria. Abnormality of macrophage activation may cause disorders like familial hemophagocytic syndrome. Eosinophilia Eosinophilia is noted in many allergic disorders systemic inflammatory conditions and malignancies (Table 12. Neutropenia Neutropenia may occur due to increased destruction or decreased production of neutrophils, and is usually acquired (Table 12. It may also occur after anti thymocyte globulin treatment for aplastic anemia, use of corticosteroids, systemic lupus erythematosus and protein losing enteropathy. Qualitative Defects Qualititave defects in leukocytes may give rise to immuno deficiencies. The work up of most immunodeficiencies needs specialized tests for estimate of immunoglobulins, T and B lymphocyte subsets and complement and functional assays. This causes delayed umbilical cord separation in the newborn and leads to repeated, severe infections and periodontitis later in life. Many other primary immunodeficiencies have quantitative defects in T, B or both lymphocyte subsets with maturation or functional defects, which lead to life threatening infections. Cl1ediak-Higaslzi syndrome is identified by its characteristic morphology showing giant lysosomes in the granulocytes and oculocutaneous albinism. Anatomic features that make young children particularly susceptible to ear infections include shorter, more horizontal and compliant eustachian tubes and bacterial carriage in the adenoids. Other risk factors include expo sure to cigarette smoke, overcrowding, bottlefeeding, cleft palate, Down syndrome, allergy and immune dysfunction. These risk factors contribute to the pathophysiology of the two common varieties of otitis media, acute otitis media and otitis media with effusion. Otoscopic examination reveals a red and bulging tympanic membrane with redu ced mobility as measured by either tympanometry or insufflation through the otoscope (pneumatic otoscopy). Rupture of the drum with ear discharge (suppuration) may have already occurred, in which case the ear canal contains an opaque yellow-green or reddish-brown fluid. Cleaning of this fluid usually reveals an intact drum, as the rupture is small and closes promptly after spontaneous perforation. Antihistaminic agents, which contribute little to the resolution of otitis media and may precipitate sinus infections due to their drying effect on mucosal secretions, are also not recommended. If a child requires a second set of tympanostomy tubes, concurrent adenoidectomy is considered. Reduced tympanic membrane mobility on either pneumatic otoscopy or type B pattern on tympanometry confirms the diagnosis. The benefit of corticosteroid administration has not been proven but a brief trial of steroids is commonly used. Insertion of longterm tubes (of T-tube design) or adenoidectomy may be considered in patients with recurrent or persistent symptomatic effusion. Earplugs are recommended while the tubes are in place to avoid entry of water into the middle ear space. It most often occurs in the first five years of life as eustachian tube dysfunction plays a central role in the pathophysiology. Clwlesteatoma, a sac of squamous epithelium extending from the tympanic membrane into the middle ear, also.
