Table 1 Acyclovir for treatment of varicella in immunocompetent children Age group Neonates Infants(01year) Children (113 years) Adolescents(>13years) Uncomplicated Complicated* Intravenousacyclovir(10mg/kg/dose),thriceaday. Indian tick typhus has various names in the local language: Kan Kapaya disease (gangrene of earlobe), Motha Govar, Ghodya Govar and Bibtya. A broad guideline only is given and for detailed protocol for echocardiography the interested reader may refer to the suggested references. The common causes of death are heart failure, multiple organ failure, hepatitis and encephalitis. Violent bouts of cough can cause syncope, rib fractures, subconjunctival hemorrhage, prolapse, hernia and alterations in intracranial pressures. Other preventive measures include sterilization of night soil before being used as fertilizer and avoiding defecation near ponds or lakes. The transfer may take longer and unable to get completed by the end of its transit time if the capillary membrane gets thickened. The treatment is largely empirical as no specific drug therapy has been found useful. Drug-induced liver injury is classified based on the histopathological features in liver biopsy. The clinical manifestations of atrial, ventricular or aortopulmonary communication therefore, show rapid changes in the first few weeks or months of life. Herpes simplex virus infection is acquired in utero, perinatal period (85%), or postnatal period. Majority of congenital malformations of the lower respiratory tract may present as a respiratory infection or a pneumonia mimicker during any time in childhood, usually in the early months of life. The humoral antibody response is the major pathway that is responsible for virus clearance and subsequent protection from disease. A viral prodrome with infection of the upper respiratory tract with influenza virus (90%) or chickenpox (57%) precedes encephalopathy. Even in these children allergen avoidance would reduce the drugs required to achieve good control. Development and psychological history (interaction with siblings and peers, temperament, any disruption of family life) helps in identifying underlying cause. This leads to a small clot following thrombin generation, which is insufficient for maintaining homeostasis. IgM antibody appears early in disease course, requires single sample and is less cross-reactive to other flaviviruses. Dupuytren contracture, gynecomastia, testicular atrophy and feminization are rarely seen in childhood. If specific diagnosis is not possible at the point of evaluation, a diagnosis of nonspecific cough is made. Nonviral Infections Leptospirosis is a frequent cause of acute febrile hepatitis in India. In case of reinfection, IgM antibody may not appear, and the level of IgG antibody titer may rise quickly within 12 weeks of infection. The cells that are produced have immature nuclei compared with the degree of maturation of the cytoplasm due to arrest of nuclear maturity. Rickettsia typhi (causative agent of murine typhus) shares similar genomes and clinical characteristics with R. European Society for Pediatric Gastroenterology, Hepatology, and Nutrition guidelines for the diagnosis of coeliac disease. History of choking, especially with associated coughing or shortness of breath, suggests foreign body aspiration, even if it does not immediately precede onset of wheezing symptoms. If culture of sputum, blood or aspirated pus comes positive, then antibiotics should be modified accordingly. Testis histopathology in boys with cryptorchidism correlates with future fertility potential. If necessary, blood transfusion may be started along with broad-spectrum and antianaerobic antibiotics. The most familiar scoring used for assessing severity of croup is the Westley Croup Score.

The classical clinical manifestation is steatorrhea described as the passage of large volume, foul smelling and greasy stools. However, when symptoms are severe or frequent, initiating preventive treatment will reduce symptoms and improve quality of life. Specimen produced by cough and containing excess squamous rather than epithelial cells indicates an upper tract origin. Myringotomy refers to a therapeutic incision usually given in anterior lower quadrant of the tympanic membrane. In iron overloaded patients cardiac failure and acute pericardial tamponade can occur. Intravaginal torsion is more common due to high investment of the spermatic cord by the tunica vaginalis. The left ventricular diastolic pressure also tends to rise and increases the left atrial pressure. The thrombocytopenia ranges from a mild to severe state and it has been covered in detail in other section. Subsequently voluntary defecation is initiated by relaxation of the external anal sphincter with expulsion of the rectal contents. A generalized inflammation of the pharyngeal structures, including tonsils, is known as pharyngotonsillitis. This is associated with drug, chronic hepatitis, chronic venous obstruction, hemochromatosis and chronic biliary disease; and (b) Macronodular cirrhosis (> 3 mm nodules)-where the liver is almost always shrunken with large bulging nodules. Hence it is important to evaluate the child and see if this is a local problem or more sinister. However, any child with cutaneous hemangioma needs evaluation for any deep seated visceral hemangioma. Anticoagulant Action Endothelial cells use three important mechanisms to inhibit thrombin generation and limit coagulation. Disease is prevalent throughout India in most of the metropolitan cities and towns. Normal adult hemoglobin (HbA) is comprised of nearly 9095% of total and minor component HbA2 accounts for 23%. They must be very cautious that they are not accidentally bitten or the saliva of the patient does not come in contact with any fresh cut, abrasions or mucous membranes of their body. Open pancreatic necrosectomy in the multidisciplinary management of postinflammatory necrosis. Physical examination should concentrate on hemodynamic assessment, so as to determine the presence and extent of shock, confirming or detecting the warning signs; and checking for bleeding manifestations, abdominal tenderness, mental state and hydration. Anemia can also be classified based on its onset into acute anemia which develops over days to weeks and chronic anemia which develops over months. Reactivation lesions are usually asymptomatic, but the most commonly affected sites being outer edge of vermillion border of the lip and ophthalmic division of trigeminal nerve. Intractable constipation Constipation not responding to optimal conventional management given for 3 months. While spirometry is useful for determining the severity of asthma, monitoring and guiding treatment, normal spirometry does not necessarily infer normal lung function. Focal proliferation of monocytes and polymorphs leads to occlusive end-arteritis or microvasculitis. Bilateral vocal cord paralysis is usually associated with congenital lesions of the central nervous system like hydrocephalus, myelomeningocele, and Arnold-Chiari malformation. The infection occurs through the bite of infected larval stage of the trombiculid mite called chiggers. The retained stools become harder and difficult to pass causing painful defecation and development of anal fissure. On a cellulose acetate strip, HbA migrates the most towards the anode followed by HbF, HbS, and HbC. Maroon-colored blood suggests significant bleeding in the distal small bowel and currant jelly stools are indicative of ischemic bowel lesion as in intussusception or volvulus. A prolonged treatment with low dose vancomycin is preferred for the repeated recurrences. This could be due to lesser vertical transmission of cariogenic microorganisms or due to the resistant structure of enamel, and quantity and quality of salivary factors acquired from the parents. Lung abscess looks like a radiolucent lesion with irregular and well defined thick margins that makes an acute angle with pleural chest wall (egg on the carpet appearance), whereas loculated empyema forms an obtuse angle with chest wall (egg under the carpet appearance).

The available evidence does not support the use of proprietary formulas or specialized ingredients over the use of locally produced and readily available foods. They are divided into four types: (1) Perimembranous, (2) Muscular, (3) Outlet and (4) Inlet defects Table 1). This guideline describes two algorithms-one for symptomatic and another for high-risk asymptomatic groups. In acute stage children with isolated limb/limbs paralysis should be advised complete rest, proper positioning of the affected limb and passive range of movement at the joints. Infections with yellow fever are usually mild; however, patients may develop severe illness with fulminant hepatitis, coagulopathy and overt bleeding. Recently, apoptosis has been shown in vitro in different cell lines for various arboviruses. It may be a serious threat in disaster struck areas of the world, where unhealthy living conditions and social disturbances prevail and the population is prone for louse infestations. Another area of special significance is poor endurance and physical fitness even with mild anemia, probably due to lower myoglobin production. In India, it is endemic in Northeast states, as in some parts of Arunachal Pradesh. These hosts have significant viremia and therefore are able to harbor, amplify and transmit the virus without developing illness, although the cycle may get aborted in pigs. Embryonicstage(36weeks):A ventral outpouching from the endodermal epithelium of primitive foregut (bronchial bud) interacts with the tissue of mesodermal origin. They more frequently present with signs and symptoms of croup, bronchiolitis or sepsis (with high temperatures). Adverse effects are less common (seen in < 10% cases) and include nasal irritation, sore throat and nasal bleeding. Acute Splenic Sequestration Crisis the event is characterized by sudden trapping of large amount of red cell mass in spleen or less commonly in liver and sudden, rapid, massive, enlargement of spleen. Mothers of one son with hemophilia and who have a family member who is a known carrier of the hemophilia gene (a mother, sister, maternal grandmother, aunt, niece, or cousin); 4. It is a rare disease usually of infants in which vascular tumor leads to decreased platelet count often presenting at birth. Catheter is removed when there is reduction of size of abscess cavity and drain output is less than 10 mL for three consecutive days. Dry Powder Inhalers Dry powder inhalers produce a fine powder of medication usually from scraping a reservoir or having individual doses encapsulated and punctured before inhalation. Idiopathic pulmonary hemosiderosis: clinical profile and follow-up of 26 children. The support should also be given on lateral sides of limb/limbs to prevent external rotation. Paroxysmal Cold Hemoglobinuria Paroxysmal cold hemoglobinuria is otherwise called DonathLandsteiner syndrome because the antibody in question is a polyclonal IgG antibody, which is a biphasic hemolysin. From the few studies that used bronchial biopsies or bronchoalveolar lavage, it is clear that the inflammatory reactions in preschool children with wheeze differ from those in older children with established asthma. The lesions are whitish, pustular associated with erythema and pruritus, and found over glans. Detectable levels of B19-specific IgM can be found within 710 days of virus exposure and remain measurable for several months before diminishing. Surgery is a day care procedure except in premature infants who are prone for apneic spells. They may enter the skin through the bite of an arthropod vector, such as a mosquito, tick or sandfly. Natural protection against a subsequent infection with rotavirus has been reported only in 40% children after a single natural infection. In these endemic regions, at any given time around 3% of population might be infected. Though most cases occur following maternal varicella, a small proportion is reported after maternal herpes-zoster infection. The principles of management include: (a) confirmation of diagnosis,(b)tomaintainhemoglobinat10g/dLbyrepeated pack cell transfusions, (c) to maintain serum ferritin are around 1,000ng/mLbychelationtherapy. The simple tubular glands of intestine (crypts of Lieberkьhn) open between the villi.

Following an incubation period of 37 days, the illness is characterized by three distinct phases: (1) febrile phase, (2) critical phase, and (3) phase of recovery. Conjunctiva is a rare route of entry for some adenoviruses and a few enteroviruses. Dactylitis requires pain medications such as acetaminophen with codeine, whereas osteomyelitis requires at least 6 weeks of antibiotics. He must avoid contact sports with significant risk of trauma such as football, cricket and high impact activities such as jumping on a trampoline. Host and Genetic Predisposing Factors Apart from gender and duration of exposure, ethnicity and host genetic factors are likely to influence disease progression and prognosis. These tests are very sensitive and a faulty sample collection will result in false results. Scratches by rabid animals are also considered another mode of transmission, which allow virus entry. A more recent study followed 1,682 children for a minimum of 6 months and determined that only 3 (0. Patients with methylmalonic aciduria with defects in the synthesis of Cbl coenzymes are likely to benefit from massive doses of vitamin B12. Routine transfusion of platelets is not required as transfused platelets are also destroyed by circulating antiplatelet antibodies. However, patients with a history of recurrent Parapharyngeal Abscess Infection of the tonsils can spread into the parapharyngeal space, resulting in high-grade fever with pain and stiffness of the neck along with swelling of the lateral pharyngeal wall. Either of paromomycin, diloxanide furoate or iodoquinol may be used to treat asymptomatic carriers, given in the regimen same as for invasive disease. Liver enzymes are commonly used in the evaluation of patients with a range of liver diseases, but they lack sensitivity and the specificity. Presence of red flag signs and symptoms requires thorough evaluation and urgent attention. Recommended doses of vitamin E are 50 mg for children below 1 year of age, 100 mg for children between 1 year and 10 years and 200 mg thereafter. Stem cell niche provides the optimal microenvironment for the growth and differentiation of hematopoietic stem cells. This complication Sickle Cell Crisis the term sickle cell crisis was defined by Diggs as any new syndrome that develops rapidly in patients with sickle disease due to inherited abnormality. The incidence varies with the associated visceroatrial situs; isolated levocardia and isolated dextrocardia have the highest frequency. The cysticercosis may involve skin or subcutaneous tissue or less commonly eyes, lungs, liver and spinal cord, etc. Trichomonas vaginalis, Entamoeba histolytica Inflammation An acute inflammatory reaction occurs in various muscular tissues, around the larvae of Trichinella. The second phase may be characterized by aseptic meningitis, myalgia, nausea and vomiting. Hemichorea and acute cerebellar ataxia have been reported in infants and toddlers with coxsackie A viral encephalitis. Vascular Access Establishing access to the vascular system-venous, arterial or both-is the first step in cardiac catheterization. Leaving behind such a testis is to see if they will recover any hormonal function. Though various surgical techniques are reported, conservative management is preferred especially in minor variants of tracheal stenosis as the tracheal lumen may widen along with the age. The hernia follows the umbilical canal along the umbilical vein, the linea alba anteriorly, and a thin layer of preperitoneal fascia in a posterior direction. They have been isolated from soil, dust, biofilms and water- both natural as well as drinking water; the species, however, may differ from one geographical area to another. Therefore knowledge of local sensitivity pattern and regular monitoring of drug resistance is critical for effective management of shigellosis. The proximal small bowel is also important in the absorption of proteins, fat, and certain micronutrients, including copper. Lymphatic drainage of the lung is complex and varies from individual to individual.

Chronic diarrhea needs to be differentiated from fecal soiling, pseudodiarrhea, encopresis, and fecal incontinence where there is uncontrolled passage of the stool in the clothes leading to embarrassing situation for the child and parents. Tracheomalacia Primary tracheomalacia is thought to be caused by congenital immaturity of the tracheal cartilage. One species of Chlamydia and two of Chlamydophila are important in causing disease in humans. Thus, cells are present in good number in thalassemia, homozygous hemoglobinopathies, following splenectomy and in obstructive jaundice. Serum alpha-fetoprotein is high (average: 160,000 µg/mL; normal full-term neonates: 84,0000 µg/mL). Radiographic findings of pneumothorax on an erect film include a thin white line of visceral pleura, usually seen in the apex of the lung, absence of lung markings beyond this white pleural line. Besides the skin, ulcerative lesions can appear on the mucosa of the nose, mouth and throat. In cases where no warning signs are present, patients should be started on maintenance fluids with isotonic fluid. Bleeding manifestations become evident in the form of petechial hemorrhages in the skin, ecchymoses or a more severe generalized bleeding. Each pediatric center should have own manual or standard operating procedures for guiding clinical practice. Treatment During an acute attack, taking care of hydration and electrolytes is essential to prevent dehydration as well as in decreasing the duration of the acute illness. Infants who are exclusively breastfed normally pass several soft or semiliquid stools each day; for them, it is practical to define diarrhea as an increase in stool frequency or liquidity that is considered abnormal by mother. Acute otitis media should be treated with antibiotics while effusion should be managed conservatively with regular audiometry monitoring. Children with signs of early organ dysfunction may deteriorate rapidly, and need to be cared for in an intensive care setting. Specimens with more than 25 squamous cells per low-power field are not considered adequate. Upper gastrointestinal endoscopy and duodenal biopsy are the mainstay of confirmatory diagnosis of malabsorption Table 2). The American Society of Clinical Pathologists has concluded that this is not a good screening test and its usage has been abandoned. Empyema may occur due to thoracocentesis, intervention for primary spontaneous pneumothorax and abdominal sepsis or spontaneous bacterial peritonitis in 2%, 2% and 1% cases, respectively. Even with early aggressive therapy the prognosis is poor and amputation of affected limbs may be required. Viremia usually does not occur during typical common cold, infection being restricted to epithelia of upper respiratory tract. In zoster, in addition to above, an inflammatory infiltrate is present in dorsal root ganglion of the affected dermatome. Intestinal transit time is decreased, the time allowed for absorption is minimized, and fluid is retained within the lumen. Factor replacement along with physiotherapy will ensure that debilitating joint deformities are avoided as also fatal bleeds. Younger infants recover more slowly from fructose exposure than older infants and children. Pregnant women should avoid contact with people suspected to have enteroviral illness. The major switch in human hemoglobin happens perinatally, with decrease in HbF and formation of adult hemoglobin (D2E2). Other causes include, but not limited to lung abscess, cystic fibrosis, asthma, interstitial lung disease, Pneumocystis jirovecii pneumonia, histiocytosis, sarcoidosis, lung infarct, congenital malformations like cystic adenomatoid malformation, lobar emphysema, and rare tumors Table 1). In blood collected with anticoagulants films should be prepared within 2 hours for best results. It consists of a nonfunctioning mass of lung tissue that lacks normal communication with the tracheobronchial tree but demonstrates blood supply originating from the systemic artery system.

Factitious hemoptysis is another condition associated with unusual symptoms and a negative evaluation. Dengue has also been noticed in temperate regions of North America, Africa, and Mediterranean Europe. Stool microscopy will show plenty of fecal leukocytes, red blood cells and macrophage. This forms the basis for prescribing a formula rich in median chain triglycerides for young infants with cholestasis. This unconjugated bilirubin binds to albumin by noncovalent bond and is then transported to liver. The direction of flow of anterior abdominal wall veins is cephalad both above and below umbilicus. Recurrent mild bleeding from the anterior part of the nose is usually due to excessive drying, trauma from nose picking, and allergic rhinitis. At least three stool specimens taken on consecutive days should be examined to exclude amebic infection of the intestines since excretion of cysts may be intermittent. Some of these viruses cause relatively mild illnesses, but in most cases the disease is fatal. The most concerning adverse effect is bleeding, the incidence of which is around 0. There should be facility based delivery by trained skilled birth attendants and unnecessary instrumentation or premature rupture of membranes should be avoided. Heme iron present in meat is not only better absorbed, but increases absorption of nonheme iron of vegetable foods. Thrombocytopenia may manifest as easy bruising or petechiae or occasionally as epistaxis or menorrhagia. Eradication of esophageal varices to prevent rebleeding is called secondary prophylaxis. The abscess wall is ragged, and its lining contains three layers: inner most composed of necrosis and occasional ameba, next layer of granulation tissue and fibrosis with few inflammatory cells, and the outer most layer of compressed normal liver tissue. Seroprevalence of IgG antibodies to herpes simplex virus type-1 in Nigerian children. Feeding Problems Normal feeding requires the creation of suction by velopharyngeal closure and compression by the orbicularis oris muscle and tongue. The presence of rubella-specific IgG antibody in a properly performed test at the time of exposure indicates that the person most likely is immune. While delayed passage of meconium, symptoms since first month of life and abdominal distension are more common in children with organic cause, fecal impaction is more in functional group. Alveolar consolidative pneumonias can be further subclassified into two groups-airspace pneumonia and bronchopneumonia. Bleeding and bruising may rarely be observed due to thrombocytopenia associated with vitamin B12 deficiency; these symptoms should also raise suspicion of leukemia or other marrow replacement disorders. Serial examination by the same examiner is the safest and the most accurate diagnostic tool. Infection In the initial period following transplantation, profound neutropenia, disruption of anatomic barriers secondary to mucositis and presence of central venous catheters are the most important risk factors resulting in bacterial and disseminated fungal infections with Aspergillus and Candida. Unilateral disease may be supported by pre-existing abnormality before the onset of clinical symptoms. A very small percentage of children tend to form biofilms in the middle ear cleft. Also in a sick child with severe anemia, which is acute in onset the treatment, gets priority rather than wasting time in elaborate investigations. Central congenital hypoventilation syndrome: changing face of a less mysterious but more complex genetic disorder. H Symptoms and signs of both conditions are nonspecific; children with bacterial pneumonia may be more ill-appearing.

Colonic histology shows cryptitis and crypt abscess along with signs of chronicity, i. The amino acid substitution in this variant was at the interface between - and -globin chains, giving rise to variants with a relatively low-oxygen affinity. These are uncorrectable coagulopathy, hypoglycemia, ascites, family history of early infantile sib deaths, maternal history of stillbirths, abortions, associated fever, anemia or respiratory distress. The illness is usually preceded or associated with fever and extrahepatic manifestations like rash and lymphadenopathy. In children, it is considered benign and self-resolving, whereas in adults it can be an acquired premalignant condition. Over a period of months to years the host response may lead to either resolution or calcification of these cysticerci. It is normally heard in infancy, childhood and adolescence and is abnormal beyond 40 years. Few children will remain symptomatic and continue to have cardiac enlargement beyond the 2nd year of life due to large leftto-right shunt despite the normal pulmonary arterial pressure. The gold standard modality: pulmonary angiography is restricted to cases where intervention is being planned. Patients who develop inhibitors no longer respond to pharmacological doses of factor concentrate therapy. Appropriate antibiotic therapy (for 46 weeks) with chest tube drainage is the mainstay of therapy. Recommendations of the Advisory Committee on Immunization Practices-United States, 2013-2014. All objects that may collect water (old tyres, broken jars, empty tins and bottles) should be disposed off. Blood transfusion needs in pediatric group especially for infants are different due to small volume of patients and immature organs which necessitate special approaches to component therapy. These may result in increased morbidity and mortality as evident by a 2-3fold increase in length of hospital stay, a 6-fold increase in the risk of mortality, and the need for colectomy (approximately 2%). During migration it may enter the glottis, causing laryngospasm and death due to suffocation. They are easily destroyed by most disinfectants and by heating to 55°C but may survive chlorination of water and in water at low temperature. Iron in the liver is deposited in parenchymal and reticuloendothelial cells of liver leading to development of progressive liver fibrosis, cirrhosis and eventually carcinoma of liver. Pharmacokinetics Pyrazinamide is readily absorbed through the gastrointestinal tract and is distributed widely throughout the body. Urgent control of the bleeding by a posterior nasal pack and protection of the airway is vital. Central Nervous System Infections Anaerobic organisms are frequently isolated from brain abscess. In clinical settings we need to decide on the following parameters: · Which group of children should be started on antibiotics at diagnosis? Neonates clear amphotericin B most rapidly thus protecting them from nephrotoxicity which is further reduced by sodium loading. The pharyngitis is often associated with whitish or gray-green exudates having an offensive odor. Ultrasonography of lymphatic vessels may reveal motile adult worms termed the filarial dance sign. Simple, age-related tasks are useful tools for the day-to-day assessment of inattentiveness and apraxia. Hence, it is logical to define chronic cough as daily cough lasting more than 4 weeks. Also a small fraction (< 1%) of a large oral dose gets absorbed passively from the oral, gastric and small intestinal mucosa. The origin is usually believed to be from the tonsillar crypts into the peritonsillar space through the tonsillar capsule, though another theory postulates its origin from supratonsillar fossa from an abscess in the salivary glands. The diagnosis can also be made by demonstration of budding yeasts on cytopathology or histology of affected tissue. A recent Cochrane review (2014) assessed the risk of publication bias by obtaining all relevant full clinical study reports relating to studies in oseltamivir and found that the use of the drug in children reduced symptom duration (but not in asthmatic children); did not affect rates of hospital admission; did not affect incidence of pneumonia; and reduced symptomatic influenza when used prophylactically. Modern tissue culture vaccines are effective in postexposure and pre-exposure rabies prevention.

Larger better quality trials are required to evaluate the new broad spectrum antimicrobials in children with persistent diarrhea; assessing effects on both the clinical and the nutritional outcomes. This prevents further extension of the thrombus and embolism, and allows the intrinsic fibrinolytic system to dissolve the thrombus over time. Studies in children aged 217 years showed that a weightadjusted dose of 1 mg/kg/day offered suboptimal exposure. Murine typhus in Greece: epidemiological, clinical and therapeutic data from 83 cases. The symptoms stop after withdrawal of milk and recur within 48 hours of milk intake. These compounds target enzymes required for synthesis of arabinans, which are essential parts of the cell wall. The aganglionic segment is recognized by absence of ganglion cells in submucosa and the presence of hyperplastic nerve trunks. The choice of blood tests depends on the clinical context; options are listed in Table 2. Instead the child may be asked to draw simple shapes that are fine motor developmental age-appropriate. This leads to further Antirabies Vaccines the use of nerve tissue vaccines is now abandoned in India after the Supreme Court ruling. Metronidazole has failed to produce desired results despite of good anaerobic spectrum. However, pancreatitis being a mild disease in children unlike adults, the diagnosis may be easily missed, if the pediatrician is not aware of the problem. Patients have severe metabolic acidosis and large amounts of methylmalonic acid in urine, cerebrospinal fluid and blood. They are often difficult to diagnose in the initial few days of the illness because they present with nonspecific viral prodromal features. Frequent burping during feeds as well as keeping infants in an upright position after feeding is recommended. Rupture of hydatid cyst can result in dissemination of protoscolices leading to multiple secondary echinococcosis. Investigations for Aspiration Investigations for small volume aspiration are generally low on sensitivity and specificity. Compound heterozygosity for HbE/-thalassemia causes a moderate to severe anemia similar to thalassemia. If the stenosis is severe and congenital, the baby will present with respiratory distress at birth. Reduction or elimination of problematic environmental exposures is the key in asthma control. Usually the choice of a third generation oral cephalosporin like cefpodoxime or cefdinir is acceptable. Vitamin C deficiencies have been reported to be associated with folate deficiency. This chapter discusses important genetic aspects of both congenital and acquired heart diseases and the developments in diagnostic and therapeutics of heart diseases in children. Presently, it has been mostly discontinued in clinical practice and is replaced by other simpler screening tests. Differential Diagnosis Allergic Rhinitis Allergic rhinitis should be distinguished from infectious rhinitis in a child with recurrent colds. Pharmacokinetics Rifampicin is readily absorbed from the gastrointestinal tract; maximal concentrations of about 7 µg/mL are attained at 24 hours after intake of 600 mg per dose. Drooling of saliva suggests epiglottitis or retropharyngeal and peritonsillar abscess. The lymph nodes are enlarged, symmetrical, may or may not be tender and are neither matted nor fixed.

Finally, cercariae escape from snail into water to encyst as metacercariae on aquatic plants. Period of infectivity ranges from 48 hours prior and up to 37 days after the rash appears. The vast majority of cases occur in developing countries among children aged less than 5 years. However, a clear etiologic role of reflux causing dental, ear, nose, throat and respiratory complications is not confirmed. Homocysteinemia Elevated plasma level of homocysteine is a strong independent risk factor for heart failure in addition to atherosclerotic disease. However, a Cochrane review concluded that steam inhalation does not offer consistent benefit. This area is copiously supplied by blood vessels (Kiesselbach plexus) and is one of the most common sites of bleeds. The cause of luminal obstruction may be an inspissated and calcified fecal mater (fecalith). Adverse effects are very common include infusion reactions like high fever with rigor and chills, nausea, vomiting, thrombophlebitis. Extraintestinal Complications They arise from spread of infection through portal circulation. Blood film shows an abundance of target cells, occasional microspherocytes, and HbC crystals especially in splenectomized patients. Such lesions represent sites of extramedullary hematopoiesis, and can be associated with several different congenital viral infections and hematologic diseases. Infectious Diseases India India alone accounted for almost 34% of global dengue burden by 2010. Enterococcus faecalis, Escherichia coli, Klebsiella, Acinetobacter baumannii and Enterobacter species are responsible for the remaining cases. It can be aggravated by exercise, as the blood may not have adequate time to get saturated as it moves more quickly through the lungs. A mixture of verrucous lesions, ulcers, nodules and papules may be seen in primary cutaneous blastomycosis. Arthralgia and/or arthritis are more common in adult females compared to adult males or children. Parents need proper counseling and advice in order to comply with giving drugs to an otherwise well child. It is primarily a disease of children of 515 years age and young adults, incidence being 110 per 10,000 in affected areas. Strongyloid has the unique ability of autoinfection and reinfecting host causing the parasite to remain in the host for decades or even life unnoticed. With progressive stool accumulation over a period of time, the rectum dilates leading to loss of sensation and effective propulsive movements required for evacuation. Sudden eosinopenia may develop secondary to inflammation or due to secondary bacterial infection and is considered a poor prognostic sign. It contributes to the distal part of internal carotid artery by joining with the dorsal aorta. Symptoms are related to the complications of heavy infections causing iron/ protein deficiency. The child becomes apathetic and lethargic that progresses rapidly to obtundation, hypotension, renal failure and shock. Flow cytometry is the most sensitive of these tests and can detect even up to 35 IgG molecules per red cell. Debridement of necrotic tissue and drainage of pus is a useful adjunct along with antibiotics to curtail local proliferation. In nature Coccidioides exist in saprobic form as soil molds while in animal hosts take a parasitic yeast-like form. The string test seems promising, although administration is difficult in young children who are unable to swallow the string containing capsule.

Murine typhus often follows a seasonal distribution and transmission rate correlates closely with population of rat fleas. The common causes of dysentery in south Asia are shigellosis, amebic dysentery, Campylobacter spp. Trivalent vaccine is used for routine immunization of infants as well as most of the pulse polio immunization rounds. If untreated, rapid downhill course may result in progressive liver disease, cirrhosis, and death. The tissue factor initiated extrinsic pathway and the surface dependent intrinsic pathway converge to produce thrombin from prothrombin. Adult-type disease is common during adolescence, but can occur from 8 years onward. Accordingly, the Howell-Jolly and Heinz bodies in the peripheral blood smear are not as useful in the diagnosis of asplenia in the neonate as once believed. Several scores have been developed to assess the clinical severity of bronchiolitis in research settings, but these measures in clinical practice are limited by substantial variability in severity assessment between observers. Relapse or resistant tumors: Other chemotherapeutic agents like irinotecan, topotecan, ifosfamide, etoposide, and certain newer drugs like ixabepilone, gemcitabine and bevacizumab are being tried in relapsing or recurrent tumors. But it is possible to administer pre-exposure vaccination to protect individuals at risk of rabies even before the exposure has occurred, namely, to the veterinary doctors, municipal workers, postmen and women, taxidermists, laboratory and research workers in the field of rabies, dog handlers, etc. The other common arterial thrombotic event is ischemic arterial stroke involving the cerebral vasculature, which manifests as seizures, apnea and poor feeding in newborns, and focal neurological deficit in older children. Counseling should include micro- or macronutrient deficiency, selection of locally available good foods, vitamin A supplementation and information regarding food and water hygiene. Even though liver biopsy is not warranted and never done for the condition itself, biopsy might show necrosis, especially centrilobular. In the absence of bacteremia, or in children with bacteremia in whom secondary foci of infection have not been found, transition to oral therapy can take place as soon as the patient is stable and able to take orally, which may be as early as 23 days after the start of parenteral therapy. These defects in turn cause impaired methylmalonyl-CoA mutase activity resulting in to methylmalonic acidemia. It is this clinical presentation of a febrile stage followed by a characteristic rash which is known as Roseola Infantum or Exanthem Subitum (Subitum refers to rapid in Latin language). Children with even moderately severe recurrent tonsillitis (except those meeting the Paradise criteria) may benefit from watchful waiting for a period of 1 year. Vectors must survive longer than the sum of the initial nonfeeding period after birth (usually 2 days) and the extrinsic incubation period to be able to infect another human. These factors increase the risk of obstruction and may manifest as cough, wheeze, chest tightness, shortness of breath, or tachypnea. Detection of etiologic agent, although difficult, may be helpful to curtail empiric therapy in lung abscess. Small bore chest catheters are equally comparable to large bore catheters in effectively evacuating the intrapleural air. Bile capillaries (canaliculi) are formed between adjacent hepatic cells, which drain toward the periphery of the hepatic lobule into a bile ductule in the portal canal. Monitoring the Response to Treatment Most children will lose weight in the initial 12 days, and then show steady weight gain as associated infections are treated and diarrhea subsides. A recent study done in infants with moderate and severe laryngomalacia reported a high incidence of associated lower airway malacias (48%) of which tracheomalacia was the most common associated lower airway anomaly (29%). First generation cephalosporins can also be used in penicillin allergic individuals who do not exhibit immediate hypersensitivity. Course of -thalassemia in these cases is usually less severe and is variable depending upon the interaction of gene and whether it associated with °/+ inheritance. Patients with single or double chain deletion will have milder clinical phenotype while patients with triple chain deletion will have clinical picture of thalassemia intermedia. Other less commonly involved organisms include Staphylococcus aureus, Clostridium perfringens, Klebsiella oxytoca and Candida. Table 4 Dummy table for recording all data for children presenting with any recurrent respiratory problem Date Duration Age Symptoms and Key Chest radiograph Treatment received Response to treatment on signs (as recorded) investigations findings follow-up Possible diagnosis for the episode 1878 Clinical History and Examination Detailed history includes information regarding the age of onset, frequency, duration and severity of symptoms along with neonatal course, subsequent hospitalizations and operations. Treatment consists of (1) management of pruritus, (2) supplementation of multivitamins, vitamin D and calcium, and (3) biliary diversion in those with refractory pruritus and disfiguring xanthomas. Following the amplification of measles virus in regional lymph nodes, a predominantly cell-associated viremia disseminates the virus to various organs by secondary viremia (day 57) resulting in systemic symptoms prior to the appearance of rash. Look for skin changes like dry, scaly skin, phrynoderma, dermatosis, and recurrent bacterial or fungal skin infections.
