Table 1 Factors implicated for the increase in incidence of bacterial endocarditis 1. Expansion of the cerebritis and formation of central necrotic focus Formation of a ring enhancing dense collagenous and vascularized abscess capsule with peripheral gliosis and fibrosis Thickening of abscess capsule. The amount of pulmonary blood flow mainly determines the clinical features and the age of presentation. If the metastases persist, metastatectomy is performed if feasible otherwise the chemotherapy is changed to alternating etoposide/carboplatin and ifosfamide/doxorubicin. Long-term outcome and prognostic factors of juvenile dermatomyositis: a multinational, multicenter study of 490 patients. Naxos disease with mutations in plakoglobin (palmoplantar keratoderma and woolly hair) and Carvajal syndrome (mutation in desmoplakin,) are two recessive forms with this type of cardiomyopathy. Treatment High-dose supplementation of vitamin E has a beneficial effect on neurologic symptoms and other fat-soluble vitamins (D, A, K) must be supplemented to correct secondary deficiency related to the malabsorptive state. Fructosamine testing may be used as a target for metabolic control rather than HbA1c since it relies on a normal structure of hemoglobin. Systolic click from truncal valve abnormalities or dilatation of the common arterial trunk may be present. The favorable environment withers and an inflammatory response is generated once the parasite is dead. Historically, all modalities of treatment in oncology including surgery, radiation and chemotherapy have been used. Vitamin D generated by the action of sunlight or consumed in the diet is hydroxylated in the liver to 25-hydroxyvitamin D. Bone age evaluation also helps to track the progression and assess the growth potential. Abdominal migraine is characteristically not accompanied by headache during the episode, and a diligent search for a gastrointestinal disorder is necessary before making this diagnosis. They are associated with a premonitory feeling that is relieved by performing the tic, are aggravated by excitement and stress, and disappear during sleep. However, the treatment of high-risk neuroblastoma remains a challenge in the best of centers. Admixture lesions are fairly important subgroup and their hemodynamic gets governed by pulmonary blood flow in classical lesions and also gets influenced by streaming, degree of obstruction to mixing and associated lesions. Assessment for other organ anomalies and developmental delay to rule out syndromic associations Table 8). As the thyroid gland descends, it remains connected to the foramen cecum by the thyroglossal duct which later becomes obliterated by the 7­10 gestational week. If not available or uninformative, indirect testing using linkage analysis can be used in familial retinoblastoma. Seizures which occur in 75­85% of patients are related to the leptomeningeal angioma. Water and sodium are controlled in a precise way, with complex interplay of various mechanisms. Apart from emergency and definitive care, supportive care is of utmost importance as a determinant of outcome in these children. Steroid responsiveness is the chief prognostic factor that determines long-term outcomes. Holistic management of primary headache should address lifestyle changes and avoidance of triggers, in addition to pharmacotherapy. Oxygen is best avoided if the lungs are normal and the neonate should be managed in room air. Patients with confirmed hypertension should be evaluated carefully to identify the underlying etiology, determine comorbidities and detect target-organ damage. Infections Common infections include peritonitis and cellulitis, which should be treated using appropriate antibiotics. The majority of cases are attributable to static structural brain lesions such as focal cortical dysplasia, hemimegalencephaly, and Aicardi syndrome. Depending upon location and size of mediastinal mass, some patients may present with symptoms and signs of dysphagia, airway obstruction (dyspnea, cough, stridor, and hypoxia) or the superior vena cava syndrome. Since there is significant ventricular dysfunction associated with the tachycardia it may not be possible to give E-blockers.

Cysticercal meningitis/encephalitis has to be differentiated from other possible etiologies of chronic meningitis such as tubercular and fungal meningitis. Vocal tics may be simple such as sniffing, throat clearing, grunting, tongue clicking, sighing, chirping, barking, or cough. It also helps to determine the timing of pulmonary valve replacement in these patients. Arrhythmias should be treated only if, they are causing symptoms or leading to hemodynamic problems such as hypotension, congestive heart failure, syncope, etc. Keratoglobus It is a bilateral generalized, noninflammatory thinning and anterior protrusion of the entire cornea from limbus to limbus. Diagnosis of defect in cobalamin metabolism requires levels of plasma and urine homocysteine and methylmalonic acid. Compare it with the normal looking seventh eight nerve complex on the left which on the postgadolinium image (B) shows an enhancing lesion also suggestive of a schwannoma. The spasms involve hands characterized by adduction of the thumb and flexion of the fingers (carpopedal spasms) and feet and occasionally laryngospasm. Examination of renal histology is advised in patients receiving prolonged therapy (2­3 years) with calcineurin inhibitors. There are significant changes in the hypothalamic-pituitary-thyroid axis and the syndrome 2496 Chapter 44. Management of retinoblastoma requires a collaboration between several specialties, viz. International Pediatric Multiple Sclerosis Study Group criteria for pediatric multiple sclerosis and immune-mediated central nervous system demyelinating disorders: revisions to the 2007 definitions. These episodes are usually noticed by others (parents, siblings, peers and teachers) but the patient himself is not aware. Table 1 History in comatose child Events leading to onset Fever, headache, vomiting Seizures at onset Sudden onset suggests trauma, seizure, stroke or poisoning Intracranial infection (meningitis/ encephalitis) Convulsive or nonconvulsive status epilepticus, poisoning (carbon monoxide, organophosphates, camphor, etc. Takayasu arteritis: utility and limitations of magnetic resonance imaging in diagnosis and treatment. Almost 10% patients either do not respond to initial treatment with prednisolone, or do so transiently and later cease to respond (steroid resistant). This error ensues as a consequence of a large globe (axial myopia) or increase curvature of refractive medium (steep cornea, curvatural myopia). Because neuroblastoma arises from the developing sympathetic nervous system, the majority of tumors express norepinephrine receptors on their cell surface. Functional difficulties Identify factors that worsen or help the primary symptoms. Group A: Decreased pulmonary vascular markings Group B: Increased pulmonary vascular markings and Group C: Transition from increased to decreased pulmonary vascular markings. It also helps prevent secondary hyperparathyroidism, which occurs if phosphate therapy is used alone. Rupture into the subarachnoid space or into the ventricular space leads to meningitis. A child presenting with an explosive onset of seizures recurring in clusters over a short period of time or as status epilepticus needs immediate treatment to stabilize and break the vicious pattern of recurring seizures. All good results depend on care taken in collecting the right sample at the right time, performing the right test in the right way and appropriate interpretation of the results. Pediatricians being the first point of contact for these children should be alert in identifying the problem and refer in time to the ophthalmologist. At first presentation, lacrimal massage is performed in office, in children below 1 year. Bosentan is metabolized in the liver and hence assessment of liver functions baseline and periodically every 4­6 weeks is mandatory. Asymptomatic infants with 4S disease have been reported to have 100% survival with supportive care only. Frequently examination of family members for subtle signs of facial weakness or scapular winging gives immediate diagnostic clue. Movement Disorders Extrapyramidal movement disorders in patients with inborn errors of metabolism are almost always associated with neurologic signs referable to other parts of the nervous system. Finally, fibrin and platelet deposition over the infected vegetation results in formation of a protective sheath that isolates the organisms from host defenses and permits rapid proliferation of the infectious agent. Children with malignancies can present with emergencies associated with various organ systems and the early recognition and appropriate management of these emergencies will save lives.

Postmortem examination of brain showed diffuse cerebral edema, perivascular myelin loss and sometimes hemorrhagic leukoencephalopathy. Resolution of the lesions occurs with continued treatment and steroid therapy probably has a preventive role. No cardiac intervention is a zero risk procedure and therefore the referring pediatrician has to be aware of those before deciding for it. Ophthalmological and ocular examinations help in differentiating from Alport disease. Ultrasound helps to rule out structural pathologies, such as obstruction, tumor and calculi. They are a panacea for children involved in sport activities where spectacle handling can be difficult. Despite improved surgical techniques, the incidence of glaucoma following successful cataract removal remains high. Shunting should not be routine and seeding of metastasis and postsurgical infection are two complications best avoided. Depending on the clinical presentation, neuroimaging either of the brain or spinal cord will help identify the tumor. The vertebral column develops around the central notochord which develops from the notochordal plate. Treatment of constipation, medications for an overactive bladder and reinstitution of a regular voiding pattern are key components of management. Electron microscopy shows initial thinning of the glomerular basement membrane, that later changes to basket weaving and lamellation. Clinical studies from endemic regions suggest that most of the parenchymal cysts are asymptomatic or are either found incidentally or are never diagnosed. Classic signs of a sensory level with or without a Brown-Sequard syndrome are rarely encountered. Ocular Toxocariasis It is another common cause of posterior uveitis among the pediatric population. Functional neuroimaging techniques can depict the activity of brain during cognitive tasks, thus enabling neuroscientists to study differences in pediatric and adult population that can further help to design treatments tailored to patients in the pediatric age group. In lowgrade gliomas, if residual disease remains after excision then chemotherapy has been used to good effect. In the family history, enquire if any of family members use wheelchair, has spinal or skeletal deformity or has any functional limitations. To mimic the circadian secretion of cortisol, hydrocortisone can be given in three doses with one-half to two-thirds of the total dose in the morning. Severe cases have structural brain defects similar to those in Walker-Warburg syndrome or muscle-eye-brain disease. Neurophysiologic tests have an important role in the diagnostic evaluation and management of the infant or child with neurological dysfunction. Oral tablets are also effective but the dosing is highly variable between 100 mg/day and 1,000 mg/day. Cornea A corneal diameter of more than 12 mm or asymmetry in corneal diameter between two corneas in the first year of life is a highly suspect finding. A short course of oral prednisolone at 1­2 mg/kg/day for 5­7 days is usually used. The supravalvar stenosis is usually suspected when child has certain dysmorphic facial features suggestive of William syndrome. Table 6 provides dosages of the drugs (other than digitalis) used to treat heart failure in children. With subsequent refinement in therapy with an aim in maximizing cure and reducing morbidity, there are now precise indications for adjuvant radiotherapy. It can identify pericarditis with pericardial effusion, myocarditis, enlargement of cardiac chambers and involvement of mitral valves, aortic valves, and right sided valves which may manifest as regurgitation. Studies have shown that intermittent clobazam therapy and diazepam prophylaxis had similar efficacy but adverse effects including drowsiness and sedation were lower in children receiving clobazam.

If pulmonary artery banding is not performed, periodic estimation of pulmonary artery pressure should be undertaken in order to prevent pulmonary vascular obstructive disease. Hormones serve as a major form of communication between different organs and tissues. Careful follow-up every 1­2 years with measurement of blood pressures and kidney function tests is recommended. The medium sized arteries are the first level branches of aorta, namely the mesenteric, renal, splenic, and coronaries, etc. It is important to rule out posterior fossa tumors, seizures and vestibular disorders before making a diagnosis of benign paroxysmal vertigo. Systemic infection is referred to as visceral larva migrans and may present as fever, cough, anorexia, malaise, seizures. Fusion anomalies seldom ascend normally and are typically located at L4-L5 lumbar vertebrae or in the pelvis. Diuretics may increase the urine output thereby allowing easier management of fluid balance. Treatment regimes start with intravenous steroids followed by intravenous immunoglobulins. It also is important to maximize muscle function and minimize secondary crippling anatomic deformities. Severe epilepsy is the rule in surviving children and is treated by conventional antiepileptic drugs. Maternal diabetes, fetal exposure to alcohol and retinoic acid have the strongest association. Intraventricular neurocysticercosis: a review of current status and management issues. Organ-specific ischemic features may be seen like stroke, seizures in central nervous system, and visual disturbances in eye. Optic neuritis is defined by acute or subacute visual loss, restricted visual fields and pain with ocular movement. The study of etiologic and demographic characteristics of intracranial brain abscess: a consecutive case series study from Pakistan. The spinous processes must be felt, any kyphosis, lordosis, or scoliosis looked for. Some of the problems envisaged include new malignancy risk, cardiotoxicity, endocrinopathies, and issues related to neurocognition and poor quality of life. It is a good clinical test to see the treatment response during follow-up assessment. Chemotherapy regimens with early use of local radiotherapy are being considered at various centers. The incidence of acquired demyelinating diseases in population-based studies range between 0. Depending upon the extent of the fold, it is referred to as epicanthus supraciliaris (eyebrow to lacrimal sac), epicanthus palpebralis (upper eyelid to inferior orbital margin), epicanthus tarsalis (upper eyelid tarsal region to medial canthus), and epicanthus inversus (from lower eyelid to medial canthus). General Physical Examination the examination should begin with assessment of vital signs Table 2). Primary testicular failure is also caused by infection, chemotherapy, and radiation damage, among others. New insights into the pathogenesis of renal tubular acidosis-from functional to molecular studies. The important etiologies for isolated micropenis are hypogonadotropic hypogonadism (either isolated or as a part of multiple pituitary hormone deficiency) and Klinefelter syndrome. Intubation with assisted ventilation under sedation with or without paralysis to improve oxygenation and limit metabolic demands. In normal healthy patient and in children with lipid storage disorder, lactate levels increase initially for first two readings followed by decline. Presence of areflexia with tongue fasciculation indicates anterior horn cell involvement (neuronopathy). Disruptions in the skin and mucosa in these patients is multifactorial in origin and can be caused by chemotherapy (leading to mucositis), surgery and radiotherapy.

Kussmaul sign, which is failure of the venous pressure to decrease with inspiration, though not specific, is commonly seen. Similarly congenital or acquired defects causing right or left ventricular pressure overload lead to ventricular hypertrophy which is associated with diastolic dysfunction. Recent studies have examined the role of biologic medications and plasmapheresis as adjunct therapy. Frequent blood tests, infections, hemolysis, underlying iron deficiency, impaired utilization of body iron and low erythropoietin levels all contribute to anemia, which then mimics the anemia of chronic disease. Cerebrospinal fluid findings are usually abnormal showing a moderate pleocytosis with elevated protein content. History for presence of rash, joint pain should be elicited to look for connective tissue disorders. They may present at any age group and are asymptomatic until serous retinal detachment develops, in which case they will present as reduced vision. This largely arises due to longer pre-pubertal and pubertal period of growth in boys than in girls. Sodium diuresis can be enhanced with a loop diuretic (furosemide 1 mg/kg 12 hourly). There is data from several centers in India, which includes approximately 700 patients. Pharmacological Agents Legislative initiatives in the United States and European Union have resulted in increased number of trials on pediatric antihypertensive agents and approval for their use Table 7). If these symptoms do not develop early, the clinician should suspect premature development of pulmonary vascular obstructive disease. Major collateral circulations between the aortic segments proximal and distal to the coarctation comprise of the internal mammary artery; arteries arising from the subclavian artery by way of the intercostal arteries and the anterior spinal artery. Febrile Neutropenia Febrile neutropenia is of great importance in the pediatric oncology unit because of its commonality and the need for early recognition and aggressive management. The disadvantages are that the algorithms used by companies are proprietary and differ among devices; this can result in variations and lack of comparability. Similar changes may be present in the brain, heart, lungs, pancreas and the gastrointestinal tract. Investigations will need to be carried out at regular intervals to monitor the disease and during episodes of acute illness. The juvenile form often has no macrocephaly but bulbar and pseudobulbar signs of swallowing and/or speech difficulty occur frequently. Hypothermia Evidence from carefully conducted studies in adults and children do not show any improvement in the neurologic outcome in head injured patients with the use of therapeutic hypothermia. However, about one-third of patients present with abdominal pain, anorexia, vomiting, malaise, or a combination of these symptoms. Currently, there is convincing evidence that an adverse periconceptual/fetal/neonatal environment may predispose individuals to developing later adult diseases. These patients come with long complicated histories and big files containing lot of investigations. Peripheral granuloma: A yellowish white elevated lesion is seen in the peripheral part of retina. Takayasu arteritis is a granulomatous large vessel arteritis of unknown etiology with stenosis or occlusion of aorta and/or its major branches. These giant cysticerci may cause mass effect, hydrocephalus, secondary infarcts and focal neurological deficits. With current technology such children require conduit change several times in their life time. The serious eye manifestations of vitamin A deficiency leading to corneal destruction and blindness, i. Children have larger proportions of body water and have higher liquid intake during the early years of their lives. Adult survival rates of 94­97% at 10­15 years have been achieved with immunosuppression and revascularization procedures.

Contraindication for Closure Irreversible pulmonary hypertension with right-to-left shunt. Sudden worsening of sensorium, high-grade fever, severe headache and meningismus may suggest rupture of abscess into the ventricular cavity. Thus, cataract at fetal nucleus or embryonic nucleus echoes the insult to growing fetus at the respective gestational age. The incidence peaks around the ages of 15­19 years and there appears to be a female predominance. The differentiation whether the hypotonia is static or progressive, helps in deciding if we are looking at a neurodegenerative disorder. Histologically they are lined by conjunctival epithelium and the subepithelial tissue contains adipose tissue admixed with collagenous tissue. Apart from muscle, connective tissue and brain, heart and eye are the other organs which are often involved in this disorder. Endocrinopathies Hypothyroidism One of the early and more prominent sign of acquired hypothyroidism is poor growth velocity and relative short stature. The epidemiology of intermittent and chronic ataxia in children in Manitoba, Canada. Adequacy of inter circulatory mixing is dictated by the location and size of communications, further modified by the pressure gradients and vascular resistances in the respective circuits. Cardiac involvement starts early and subclinical disease is seen in onefourth of patients under 6 years of age. Thus milk and egg along with other animal sources enriched the diet with cholesterol and cholesterol generators. Rarely, the predominant obstruction may be at the pulmonary valve level, and in such babies, balloon pulmonary valvuloplasty may help increase pulmonary blood flow. Prednisolone may be discontinued if the child is in sustained complete remission for 6­12 months. Unrelated transplants, as of today are very costly and risky, and need more research to make them easy to perform and safe to exercise. Severe vitamin D deficiency has been described to cause dilated cardiomyopathy which may be life-threatening. Attention to electrolyte balance, sensorium and the presence of infection are important. The traditional neurological examination can be done in older children and adolescents, however, the scheme and detail of examination needs to be modified for infants and young children. Compare the two eyes; they may differ in size of oscillation (dissociated) or in direction (disconjugate). The triggering cause such as leukemia or infection, would need to be treated simultaneously, making the entire management very complex and can usually be carried out only in centers with the requisite expertise. A few children may actually be able to maintain reasonably good control without any insulin though it is advisable not to omit insulin altogether. Periodic monitoring of growth and development and advice regarding calcium-rich diet and exercise to improve bone strength needs to be conveyed to the shared care pediatrician. It generally regresses within 18 months but complete regression may not be seen in those whose onset was after 2 years of age or with Tanner stage 3. Corticosteroids (prednisolone 1 mg/kg/day) may be given for initial 2 months and benefits by reducing morbidity and mortality, but definitive data regarding lack of progression to constrictive pericarditis is lacking. Calcium deficiency rickets includes nutritional, malabsorption, vitamin D dependent and renal rickets. Osteoporosis-pseudoglioma Syndrome this is a rare autosomal recessive inherited condition characterized by fragility fractures of long bones and vertebrae, blindness and learning difficulties. Maintenance of Fluid Balance Fluid and electrolyte prescription depends on the volume status of the patient. Magnetic resonance imaging of brain with gadolinium is the imaging modality of choice for diagnosing brain abscess. Malignancies A 2-year-old boy was brought with complaints of inability to bear weight and walk since past one month. Table 1 Definitions: quantification of proteinuria Terminology Proteinuria Nonnephrotic range proteinuria Nephrotic range proteinuria Protein (mg/m2/hour) >4 > 4 ­ < 40 > 40 Protein: creatinine ratio (mg/mg) > 0.

Antiplatelet agents are given as a routine to avoid thrombosis in stenosed vessels. Neurofibromatosis (von Recklinghausens Disease) It is characterized by neurofibromas of skin, central and peripheral nervous system, iris, viscera, bony defects, specific pigmented skin lesions, the cafe-au-lait spots in the peripheral variant and bilateral acoustic schwannomas; the ocular features consist of yellow brown iris hamartomas (Lisch nodules). Ask for maternal intake of antiepileptic drugs such as valproate, carbamazepine and other teratogens. Latex agglutination test: an adjunct to the laboratory diagnosis of pyogenic bacterial meningitis. Early intervention for hypertension, microalbuminuria, retinopathy and surveillance for foot care and neuropathy are helpful in delaying or minimizing progression. In infants and children, the most common emergency is hypercyanotic spell (Tet spells). It causes distal leg paresis and sensory loss in and around the perineum and anus (saddle anesthesia), as well as bladder, bowel, and pudendal dysfunction. Staging the first step in staging is to determine whether the disease is intraocular or extraocular. Duration can however be shortened in case of single antibody positivity and a provoked thromboembolism. In centers where facility for cardiac surgery is not available, intrapericardial instillation of streptokinase by dissolving the fibrinous components of the exudates is thought to be helpful. Experiments have shown that reflux of infected urine can cause renal parenchymal inflammation and scarring. Local control Surgical resection of primary tumor site is done after induction chemotherapy. Pediatricians, however, must remember that the two forms may simultaneously or sequentially present in a single patient. Others Thallium 201 scintigraphy shows cold areas in affected myocardium, but is nonspecific and can occur in cardiomyopathy. Hereditary motor and sensory neuropathy is a genetic disorder involving the motor and sensory nerves. The titration of mercaptopurine to allow absolute neutrophil count values between 750/mm3 and 1500/mm3 has shown to improve outcome. Recurrence of infection can occur and the reactivation occurs at the edge of a previously healed lesion. Therefore, these defects arise from an interplay of a number of genes along with gene-environmental interactions. In resistance or inability to wean systemic corticosteroids, oral mycophenolate mofetil has been found to be successful. Human ability to see colored products is to prioritize colored fruits and vegetables in the healthy diet plate to minimize this oxidant stress. The most common microorganisms causing brain abscess in children worldwide are aerobic and anaerobic streptococci. It typically is a panarteritis involving all the three layers of vessel wall producing a typical pathology characterized by stenosis, occlusions, aneurysms and rarely rupture. Febrile seizures are the most common convulsive event in children between 6 months and 60 months. Increased levels of an intermediate sulfoxide metabolite of albendazole when a combination therapy is instituted contribute to heightened cysticidal activity. Blood cultures are often sterile unless hematogenous spread of infection has occurred. It represents the most common type of developmental cataract in a normal-sized eye. Therapy with corticosteroids results in remission of proteinuria, usually by 10­14 days, diuresis and loss of edema. Due to the location of the ureteric orifice in relation to the urethral sphincter, girls, but not boys, have incontinence.

Hepatic ductular hypoplasia

A progression-free survival of 98% at the end of 2 years has been achieved in children. Patients who respond to treatment do so within 3­6 months; those that fail therapy with one regimen may respond to different agents. Clinical Features Neuromyelitis optica is an inflammatory disease of the central nervous system that preferentially affects the optic nerves and spinal cord. Treatment with retinoic acid has been associated with remissions in a small number of patients. Only prednisolone and prednisone are of proven benefit in the treatment of proteinuria. Adenohypophysis has five cell types (somatotropes, lactotropes, corticotropes, thyrotropes and gonadotropes) secreting six hormones Table 1). While in early stages light microscopy may be normal, IgG deposits are seen on immunofluorescence and in the subepithelial region on electron microscopy. It is balanced by decreased aqueous secretion due to ciliary body damage versus continued conjunctival scarring/shrinkage attributed to obstructed outflow pathway. The hydrogen nuclei (protons) present in various tissues of the body are used to generate signals from the body which are detected and processed by the equipment to generate useful images. Rupture of the cloacal membrane results in herniation of lower abdominal components to the wall and characteristic features. Clinical features of Bartter syndrome include polyuria, polydipsia, salt-craving, muscle cramps and failure to thrive. Definitions are based on blood pressure taken on greater than or equal to three separate occasions. The number of rods and percentage of fibers with rods do not correlate with disease severity, and a variety of abnormalities of contractile function (including altered thin filament length and abnormal calcium utilization) and variable degrees of myofiber smallness (hypotrophy) have been found in muscles harboring nemaline myopathy. Cardiovascular Disorders Noninfectious Pericarditis Pericarditis may be present in any connective tissue disorder and presents as acute or chronic pericarditis with or without effusion. Systemic symptoms classified as B symptoms that are considered important in staging include fever greater than 39єC for more than 3 days, weight loss greater than 10% over 6 months, or drenching night sweats. Subcutaneous fat necrosis It is thought that the ectopic 1,25-dihydroxyvitamin D produced by inflammatory, mononuclear cell infiltrates in these lesions increases gastrointestinal calcium absorption. Most are asymptomatic, but some may interfere with vision or cause hypothalamic disturbance such as precocious puberty, or other neurological symptoms. A recent meta-analysis concluded that antihelminthic therapy was associated with increased rate of seizure control and resolution of lesion in cases with single lesion. A classification based on age of onset of these nonepileptic disorders is given in Table 1 and some of the more common nonepileptic disorders occurring in different age groups are reviewed. The presenting symptoms are generally related to an enlarging primary tumor in the posterior fossa and that of metastatic dissemination in a progressed disease Table 9). Initially, the disorder presents as a cerebellar ataxia, followed in a few years by oculomotor apraxia 2370 Indian context Agarwal ethnic background. Compensatory neurohumoral activation mechanisms are able to restore cardiovascular function to a normal homeostatic range for a short period of time. Resection of all metastatic lesions, if possible is included in the local therapy. The course, typically, is fluctuating in childhood with periods (days to weeks) of worsening interrupted by periods (days to weeks) of improvement. Examination A thorough top to toe examination is needed for all patients with an emphasis on growth, detailed systems review and joint examination. Rarely, emergent decompressive craniectomy may be needed in cases with malignant cerebral edema not responding to medical measures and with impending risk of herniation. As mentioned previously, there is a paucity of long-term studies looking at effects of pediatric hypertension and hence definitions are just based on normative distribution of systolic and diastolic blood pressure in healthy children Table 1). Other conduction abnormalities such bundle branch block and heart block may be present secondary to involvement of Purkinje system. Azathioprine is started at 1 mg/kg/day and increased slowly to reach a maximum of 2. It may predispose to renal parenchymal infection by allowing ascent of bacteria from bladder to the upper urinary tract.

Matthew Wood syndrome

Ulcerative lesions in crevices and creases such as the groin and perianal region, behind the ears and under the breasts mimic bacterial or fungal infections. Pendred syndrome is caused by a mutation in the pendrin gene affecting the transport of ions in the follicular cell as well as in the inner ear resulting in hypothyroidism, goiter and sensory neural deafness. This class does not require specific treatment and generally has a good prognosis. The ultimate goal of clinical evaluation and investigations is to offer preventive diagnosis for future children and possibly identify and treat pre or pauci symptomatic individuals in the family. Hypothalamic disturbances can lead to precocious Vasculitis Corticosteroids may be beneficial because of their antiinflammatory effect. The white matter, consisting of longitudinal bundles of nerve fibers, is regarded as being divided into three columns. Localized hypertrophy of the infundibular region develops in some producing subvalvar obstruction. Patients with idiopathic hypercalciuria represent a complex interaction between genetic and environmental factors. Dipsticks are commercially available, chemically impregnated reagent strips that employ a colorimetric change for pH, specific gravity, protein, blood, glucose, ketone, leukocytes, and nitrites in the urine. Depending on the presentation relevant family history could include history of epilepsy, sibling deaths, muscular dystrophy, degenerative disorders, migraine, early cardiac deaths or cerebrovascular disease, etc. Sometimes learning the use of gestures also helps in improving communication and quality of life. It is better to keep the pupil mobile, by using homatropine rather than keeping it fully dilated with atropine. As the degeneration progresses, the cyst content changes from hyperintense to hypointense on T2 images and the cyst wall changes from hypointense to hyperintense appearance. The addition of Doppler imaging has further provided an impetus to the role of ultrasound in evaluation of the pathological processes involving the brain. Respiratory aids are provided to those with respiratory insufficiency and these include assisted cough and hyperinsufflation devices, Percussionaire, noninvasive ventilatory support, or mechanical ventilation via tracheostomy and chest physiotherapy. Healthy children on salt restriction can reabsorb 99% of the sodium from the nephron with only 1% being excreted. The use of multiple daily doses is advised as serum phosphate levels return to low baseline values within a few hours of phosphate supplementation. Puberty is considered precocious, if its onset occurs before 8 years in girls and 9 years in boys. Majority of recurrences occur within 3 years of diagnosis and are extremely rare after 5-years of age. Edema that does not respond to maximal doses of oral furosemide requires coadministration of thiazides. The likely etiology is degenerative and metabolic disorders; rarely this may be the presentation with slowly growing neoplastic lesions and toxin exposure. They have autosomal dominant, autosomal recessive or X-linked inheritance patterns. Polyuria is caused by osmotic diuresis due to presence of excessive solutes in the tubules and impaired urinary concentration due to persistent hypokalemia. Color Doppler echocardiography adds to the information by exactly locating the origin of flow turbulence, whether valvar, subvalvar or supravalvar. In the first circuit, oxygenated blood flows from the lungs to the left heart only to get pumped back into the pulmonary circulation (through the pulmonary artery arising from the left ventricle). Systemic Disorders Ambulatory Blood Pressure Monitoring Blood pressure demonstrates a circadian rhythm and is affected by sleep/wake cycle and activity. Vitamin dependency states result due to mutations in the enzyme protein that affects utilization or binding of the vitamin or mineral co-factor. Tumors of the axial skeleton may have varied clinical presentations based on the site of occurrence. Combinations of two analgesics or codeine with paracetamol are available and used in adults, but not much information is available for children. The murmur has typical systolic ejection qualities and is best heard over the upper left sternal border with radiation to the lung fields. The symptoms are minimal as long as the myocardial hypertrophy compensates for the volume overload without undue increase of left ventricular end diastolic pressures. The clinical features are progressive hydrocephalus, secondary brainstem dysfunction, feeding and respiratory complaints including apnea.

Ventriculoperitoneal shunt or endoscopic third ventriculotomy for hydrocephalus if indicated b. Nitrate reductase It is based on reduction of nitrate to nitrite by nitrate reductase enzyme present in most coliforms. Search for Source of Infection A thorough and extensive search for the source of primary infection should be done in all cases. Primary deviation: Deviation of the paretic eye measured with the normal eye fixing. All these cardiac defects tend to decrease the antegrade aortic blood flow in utero. The onset and progression of puberty and eventual height are normal in these children. X-ray of the knees 6 months after starting treatment helps to monitor healing and progress. Similar decline per capita salt consumption and tobacco use and increasing physical activity were major achievements. Most of the tumors secrete both epinephrine and norepinephrine with epinephrine predominating in adrenal tumors. Identifying the different organ systems involved and assessing the severity at the time of diagnosis enable one to select the appropriate treatment regimen, prognosticate the disease course and guide the follow-up of these patients. Slowly progressive resulting in severe respiratory insufficiency in the first decade: i. Other reported risk factors such as hypocholesteremia, viruses, toxins and medications have also been reported. This is exemplified by the fact that children who turn out with a poor epilepsy outcome do not begin so at start of epilepsy. They are the second most common form of pediatric cancer, exceeded only by leukemias. Skin Biopsy It is a simple and less traumatic procedure which requires minimal sedation. Symptoms of patients who relapse on corticosteroid taper may be controlled with weekly infusions of methylprednisolone (30 mg/kg, not to exceed 1 g/week). Information from prospective series show that fluid overload in critically ill children is an independent predictor of mortality. During the testing, the child is deprived of water to cause dehydration up to 5% of baseline weight or till serum osmolality goes above 300 mOsm/kg. Epidemiological studies in India have identified vitamin A, vitamin C and vitamin D deficiency to the order of 75% in various segments of the population including children. In order to ensure that no case is missed, it is mandatory to report cases of acute encephalitic syndrome. If there is no focal lesion, the biopsy is taken from the nondominant frontal lobe. Most experts would administer a second dose of vitamin D at 4 weeks if healing of rickets does not occur after first dose, and make a diagnosis of refractory rickets if no healing is observed even after second dose, i. Complications and limitations include residual left to right shunt, incomplete closure, hemolysis, distal embolization, and endocarditis. There is wide variation in the way the disease manifests and hence demands individualized modifications to the treatment delivered. The ratio of intracranial/intraspinal neoplasms in children depends on the histology of the tumor. The hemodynamic advantages associated with the bidirectional Glenn are improved effective pulmonary flow, reduced total pulmonary flow, and less left ventricular volume overloading. In addition children may differ in their innate capacity for myelin repair leading to fundamental differences in the appearance of white matter lesions. Mechanistically, it represents failure of intrinsic homeostatic mechanisms to terminate a seizure after onset, such that it would not resolve without extraneous intervention.
