Older patients with back pain usually respond to a back-strengthening exercise program arthritis in dogs hip joints 400mg etodolac otc. Patients with unacceptable deformity who are too old for brace treatment require surgical correction arthritis cramps in feet purchase etodolac 400mg without prescription. Often this requires a combination of anterior release and posterior spinal instrumentation and fusion osteoporosis arthritis in feet purchase discount etodolac line. He now has a markedly improved appearance and no further progression of the kyphosis arthritis medication during pregnancy purchase etodolac 400mg online. Lateral radiographs of the midthoracic spine in an asymptomatic 16-year-old male with moderately severe kyphosis arthritis pain relief medication for dogs generic etodolac 200 mg. There is severe wedging rheumatoid arthritis zija discount etodolac 200mg on line, loss of vertebral height, and end plate irregularity present on these films. If further collapse was to develop and the kyphosis became more severe, surgical intervention would be necessary. In rare cases, adolescents may develop a lesion that is a fracture of the posterior vertebral apophysis, which displaces posteriorly into the spinal canal and acts like a herniated disk. When a patient has severe symptoms, treatment should begin with bed rest, analgesics, and antiinflammatory agents. When the symptoms have begun to abate, physical therapy for lumbar and paraspinal strengthening is helpful. Patients who present with progressive neurologic deficits require early surgical excision. Similarly, patients who fail to respond to a significant period of nonoperative management also require disk surgery. Spinal fusion is not required unless the patient shows evidence of instability, which is quite rare. A B Scoliosis Idiopathic scoliosis, a combination of lateral deviation and rotation of vertebral bodies, does not always produce back pain. When painful scoliosis is present, a careful search for the cause of the symptoms must be undertaken. Infection, tumor, a spinal cord syringomyelia or diastematomyelia (more common with left thoracic curves), and occult fractures may produce clinical findings that resemble idiopathic scoliosis but, in contrast to idiopathic scoliosis, cause significant chronic pain as well. Any patient with painful scoliosis should have a careful evaluation for other spinal anomalies causing the pain. Kyphosis that results from congenital vertebral deformities is often obvious early in life and may be rapidly progressive. The spinal cord may become tented over the apex of the deformity, producing symptoms and signs of spasticity in the lower extremity and bladder. Progression of deformity is dangerous; congenital kyphosis is the spinal deformity most often associated with paraplegia. Etiology Idiopathic scoliosis begins in the immature spine, although progression of preexisting curvatures may occur in adult life. Hormonal factors appear to play a role in curve progression, inasmuch as severe curves occur much more often in girls. Some studies have demonstrated abnormalities of proprioception and vibratory sensation in affected patients, which suggests that abnormalities of posterior column function may contribute to the development of curvature. Other investigators have implicated cerebellar or muscular (myopathy) dysfunction as a possible cause of spinal imbalance. Curves occur more frequently in individuals with affected 1st-degree relatives, but transmission is not Mendelian. Although curvature is more likely to develop in the daughters of affected mothers than in other children, the magnitude of curvature in an affected individual is not related to the magnitude of curvature in relatives. It appears likely that a combination of genetic predisposition and other undefined factors is responsible for development and progression of idiopathic scoliosis. Intervertebral Disk Herniation Intervertebral disk rupture is much less common in children than in adults. Because most such patients are treated nonoperatively, the absolute incidence of the disorder is not known. In the United States, fewer than 1% of patients undergoing diskectomy are younger than 16 years. The frequency of symptomatic intervertebral disk herniation may be more common in Asian persons than in white persons, perhaps because of the smaller size of the spinal canal. In other patients, congenital anomalies of the lumbar spine, such as transitional vertebra or spina bifida occulta, are noted. The symptoms of a herniated lumbar disk in adolescents differ somewhat from those in adults; this may delay recognition. The initial complaint in adolescents is significant low back discomfort; it is only months later that the symptoms of leg discomfort become more noticeable or prominent. The affected adolescent has poor back mobility, often with paravertebral muscle spasm. Neurologic signs are less likely to be prominent in the adolescent with herniated disk than in the affected adult. Clues to suggest a lumbosacral radiculopathy include abnormal straight leg or cross Classification Idiopathic curves are grouped into infantile (birth-3 years), juvenile (4-10 years), and adolescent categories on the basis of age at onset of curvature. The infantile form differs enough from the other varieties to be considered a distinct entity. Infantile idiopathic scoliosis is rare in the United States, probably accounting for fewer than 1% of new cases of idiopathic scoliosis. The majority of patients are males, and most curves are convex toward the left rather than the right, as in the other varieties of idiopathic scoliosis. The diagnosis of idiopathic deformity is appropriate only when radiographic studies show no evidence of congenital vertebral anomalies. Although many infantile curves resolve spontaneously, others progress relentlessly and are very difficult to treat effectively. Observation is appropriate until 6 months of age in infants with mild idiopathic scoliosis, but prompt referral should be made if curves persist or increase during the period of observation. Others, particularly those that occur in older children, may be early manifestations of adolescent idiopathic scoliosis. Others remain stable until the onset of the growth spurt and then progress unless treated. There is no reliable method of predicting the behavior of juvenile curves at the time of diagnosis, but, in general, high-magnitude curves in young patients are more likely to increase with growth than are smaller curves in older children. The majority of patients with juvenile curves greater than 25 degrees at the time of diagnosis require some form of active treatment. Treatment must begin at the time progression is first documented if severe deformity is to be prevented. Most cases of idiopathic scoliosis in North America develop around the time of the adolescent growth spurt. Often parents and children are unaware of the presence of curvature at the outset. Nerve root impingement, intervertebral disk disease, and spinal cord compression are uncommon in young patients with idiopathic scoliosis. Pain is so rare that children and adolescents with painful curves must be carefully studied in order to exclude neoplastic and inflammatory processes of the spinal column or neural canal. Idiopathic scoliosis is usually a painless disorder during childhood and adolescence. Severe structural curves may cause no pain until degenerative changes develop in adulthood. Most programs concentrate on children in the late juvenile and early adolescent periods. The most common screening method employed is the forward-bend test, based anatomically on the vertebral rotation that accompanies lateral spinal deviation. Associated clinical findings include shoulder asymmetry, unequal distances between the medial borders of the elbows and the flanks, and apparent leg length inequality or pelvic tilt. Breast asymmetry, caused by forward rotation of the chest wall on the side of the curve concavity and backward displacement of the chest wall on the convex side of the curve, is often present in affected girls. The threshold for "identification" on screening examination is subjective, and it is not surprising that the incidence of spine asymmetry detected by school screening programs varies with the method of screening and the experience of the examiner. Follow-up radiographic studies of children thought to have abnormal curvatures on school screening examinations indicate an incidence of scoliosis in screened children of less than 15% (range, 0. The incidence of curves greater than 20 degrees at the time of primary screening is probably less than 0. Simple devices such as the scoliometer determine spine asymmetry by measuring the angle of trunk rotation at the apex of the rib hump. The 1st response to a positive school screening examination should be a repeated physical examination. If asymmetry is confirmed, a single standing posteroanterior spine film, including vertebral levels T1 to S1, should be obtained. Referral is appropriate for skeletally immature children or adolescents with curves greater than 20 degrees. Natural History the natural history of curvature in patients with spine asymmetry is highly variable. Factors that appear to be associated with risk of progression include the magnitude of curvature at the time of detection, the chronological and skeletal age of the patient, the pattern of curvature, and the menarcheal status. Immature patients with largemagnitude curves are far more likely to experience progression than are more mature patients with small curves. Progression of curves after skeletal growth is uncommon in idiopathic thoracic curves of less than 30 degrees at the end of growth but is likely to occur in patients with curves greater than 50 degrees at maturity. Unacceptable deformity, back pain, chronic fatigue, and decreased work capacity are common. Premature degenerative arthritis and nerve root impingement caused by deformity and osteophytic spurring occur in patients with lumbar curves or double thoraciclumbar curves. Technetium bone scanning shows increased uptake in the T10 vertebral body in a 15-year-old boy. The condition did not respond to antiinflammatory medications, and surgical excision was necessary. The patient, a 13-yearold girl, had a severe double-curve pattern with significant accompanying deformity but no pain. Surgical treatment was warranted to halt progression and restore spinal alignment. Return to school is usually possible within 3 weeks; most activities of normal life, including sports, can be resumed within 6 months. In many instances, no postoperative immobilization is required; in other cases, a removable lightweight plastic orthosis can be employed. Treatment the goal of treatment in idiopathic scoliosis is to bring a patient to skeletal maturity with a cosmetically acceptable, balanced, and stable curve that is unlikely to progress in adult life. Mature adolescents with curves less than 30 degrees need no treatment beyond initial evaluation. Patients with juvenile scoliosis and less mature adolescents with curves between 10 and 20 degrees should be monitored at 6-month intervals with single standing posteroanterior spine radiographs. Active treatment is indicated for growing patients with curves greater than 30 degrees. Brace treatment remains the standard method of nonoperative treatment of idiopathic curvature. Surgical treatment is appropriate for patients with curves too severe for brace treatment. Documented progression in spite of nonoperative treatment is another indication for surgical intervention. Improved instrumentation and internal fixation devices, intraoperative monitoring of spinal cord function, and autologous transfusion have improved the safety and efficacy of surgical correction. In most Tumors of the Spinal Column Persistent back pain, muscle spasm, and abnormal trunk posture are ominous findings in children. Neoplastic disease must be considered in patients with no other obvious source of pain (see Table 35. Primary Lesions of Bone the most common primary bone tumors affecting the spinal column in children are osteoid osteomas. Although benign, these lesions may cause considerable back pain and local bone destruction. Osteogenic sarcoma, a malignant lesion of bone, occurs less commonly in the spine than in the long bones of children. Unexplained pain is the hallmark of spinal neoplasia and is usually the presenting complaint. In other instances, as in osteoid osteoma, the relief of symptoms that occurs with nonsteroidal antiinflammatory agents is so characteristic that it is considered a diagnostic finding. Paraspinal muscle spasm, tenderness in the soft tissues on the side of the spinal column, and alterations in spinal configuration are common. Scoliosis, loss of lumbar lordosis, or accentuations of thoracic kyphosis may be present. Children with back pain should be suspected of having a tumor of the spine or spinal cord until it is proven otherwise. Note the destruction of the disk space and vertebral bodies with the beginning of anterior ossification. In this patient, fusion occurred spontaneously, and the patient is now asymptomatic. These may not show small lesions hidden in vertebral pedicles or posterior elements; other studies are often necessary. The success of treatment depends in large part on early discovery and intervention. Tumors of Neural Elements Back pain, lower extremity weakness, and sphincter disturbances are common manifestations of neoplasms of the spinal cord. Although such lesions are rare, they must be suspected in children with unexplained back or leg pain, weakness, sensory or reflex abnormalities, bowel or bladder incontinence, or unexplained gait abnormalities.

In some instances rheumatoid arthritis qof discount 200mg etodolac fast delivery, the limitations are directly related to discomfort or disability from arthritis rheumatoid arthritis in upper back purchase etodolac pills in toronto, but school absences and the discontinuation of sports and social activities may also be secondary to depression or psychogenic pain arthritis lyme order generic etodolac pills. Chronic pain syndromes in children are frequently associated with a history of psychosocial stress as well as depression arthritis car show order 400 mg etodolac amex. Travel history is important in considering Lyme disease because the causative agent rheumatoid arthritis specialist new zealand cheap etodolac 400mg otc, the spirochete Borrelia burgdorferi arthritis prognosis cheap etodolac master card, is transmitted by the bite of a deer tick that has a restricted geographical distribution. Lyme arthritis characteristically causes episodic joint effusions in 1 or several large joints, most commonly the knee. In the United States, endemic regions include the northeast (Connecticut, Rhode Island, and Massachusetts), mid-Atlantic (Long Island, New York City suburbs, New Jersey, southeastern Pennsylvania, Delaware, and Maryland), and the upper Midwest (parts of Minnesota and Wisconsin). Although these endemic areas may be gradually expanding, a child who has not traveled to these areas is unlikely to have Lyme disease. Arthritis may be the only symptom of Lyme disease, and may not appear until up to 2 years after the tick bite; a history of the classic rash (erythema migrans) is helpful but not necessary for a diagnosis of Lyme disease. Review of Systems Constitutional Symptoms Some rheumatic diseases, including several forms of childhood arthritis, are systemic illnesses and cause fevers, poor appetite, weight loss, and fatigue. The absence of these symptoms helps eliminate specific illnesses as diagnostic possibilities. A decline in appetite is common in many arthritides, though when associated with documented weight loss may indicate more severe or systemic illness. Children with Crohn disease or ulcerative colitis, both of which are often accompanied by abdominal pain and diarrhea, may demonstrate poor appetite and failure to thrive. An increase in weight should raise the suspicion of hypothyroidism or fluid retention. The clinician should attempt to Family History For some diseases, a positive family history increases the likelihood that other individuals in the family have that disease, but the genetics of the rheumatic diseases are complex, and none of the genetic associations are strong enough to confirm or eliminate a diagnosis solely on the basis of the family history. Within the rheumatic diseases, the family history is most helpful when diagnostic possibilities include enthesitisrelated arthritis, psoriatic arthritis, or lupus. Approximately 30% of patients with lupus will have a 1st-degree relative affected by lupus. Less common familial illnesses that may cause rheumatic complaints include familial Mediterranean fever, mucopolysaccharidoses, hemophilia, and muscular dystrophies. Social History Determining the extent to which the problem has limited usual activities helps to gauge the severity of the problem. The presence of proximal muscle weakness, often associated with fatigue and poor endurance, is characteristic of polymyositis and dermatomyositis. The macules are usually not pruritic, appear with the fever spikes, and may resolve completely when the fever is absent. Acute rheumatic fever is associated with a specific rash, erythema marginatum, in only approximately 5% of cases. Erythema marginatum is also a fleeting rash, changing in distribution over time, and consists of erythematous patches with serpiginous borders that tend to migrate, usually over the trunk and proximal extremities. Because of their changes in distribution, families often confuse both of these rashes with urticaria. The characteristic skin lesions in dermatomyositis are pathognomonic: a heliotrope rash is a purpuric discoloration of the upper eyelid, often accompanied by edema. These are sometimes scaly and can be confused with psoriasis or eczema, were it not for the distribution. Lesions similar to the Gottron papules occasionally also appear on the extensor surfaces of the elbows and knees and over the medial malleoli at the ankle. Erythema migrans occurs in up to 80% of cases of Lyme disease, days to weeks after the tick bite. The lesion expands, beginning as a small papule and then forming a large erythematous, circular patch, usually at least 5 cm in diameter and often with some clearing in the center to produce a target-like appearance. If Lyme disease is left untreated, the lesion usually lasts for several weeks and then gradually resolves. If dissemination occurs, some individuals develop multiple secondary lesions that appear similar to the primary lesion. Scleroderma causes tightening, thickening, and the development of a waxy texture to the skin, and it frequently begins on the hands, feet, and face. Acute anterior uveitis (involving the iris and/or ciliary body) can be seen with reactive arthritis and enthesitisrelated arthritis. Sarcoidosis in children is usually associated with posterior uveitis, although anterior uveitis also occurs. Dysphagia suggests esophageal dysmotility, which may occur with inflammatory myopathies and scleroderma. Asking whether the child needs to cut food into small pieces, needs to drink an unusual amount of fluid with meals, or takes a long time to complete a meal are helpful ways of assessing dysphagia. Particularly with young, fearful children, this period of observation may give a better sense of the range of motion or the degree of discomfort in the joints than the formal examination, when the child may be uncooperative. Fever, especially in the child with arthritis or localized extremity pain, may suggest an infectious process. Tachypnea suggests the presence of cardiac or pulmonary disease and hypertension increases the suspicion of renal disease. In any child with joint complaints, it is important to examine all of the joints because arthritis may be detected in joints that have not had symptoms. The neck and the joints of the upper extremities are best examined with the child in a sitting position. Children with inflammation in the joints of the cervical spine usually have limitations in extension, lateral flexion, and rotation. This is tested by asking the child to look up at the ceiling, touch each ear to the ipsilateral shoulder, and touch the chin to each shoulder. Children with chronic arthritis of these joints develop micrognathia and often retrognathia as a result of delayed mandibular growth. The oral opening is often decreased, and there may be pain with opening and closing of the jaw, and tenderness to palpation directly over the joint. Shoulder arthritis is identified by detecting limited range of motion and pain with motion. With the upper arm abducted to 90 degrees and the elbow flexed to 90 degrees, the clinician can then rotate the upper arm superiorly and inferiorly (external and internal rotation of the humerus, respectively), noting any limitation or pain. Alternatively, the patient can be asked to abduct and extend the arm, reaching behind the head to touch the contralateral scapula, and then to adduct and extend the arm, reaching behind the back and upward, again touching the contralateral scapula. The acromioclavicular joints and the sternoclavicular joints are occasionally affected by arthritis and should be palpated, noting any swelling or tenderness. Elbow extension and flexion should also be tested, along with supination of the forearm and hand. Many children can normally hyperextend their elbows, and the degree of extension is variable; therefore, it is helpful to compare the range of motion of each elbow to the contralateral side. Many children with wrist arthritis develop swelling on the dorsal aspect of the wrist that may be fairly large but is usually nontender. Extension tends to be more limited than flexion in wrist arthritis, and radial deviation tends to be more limited than ulnar deviation. Children with arthritis frequently complain of pain or withdraw their arm with maneuvers to test flexion and extension of the wrist. Arthritis of the wrist or any of the small joints of the hand decreases grip strength. Each hip is taken through its range of motion, beginning with flexion by trying to bring the knee as close to the chest as possible. With the hip and knee each flexed to 90 degrees, internal and external rotation are tested by keeping the knee in a fixed position and turning the lower leg laterally and medially, thereby rotating the femur. The hip and knee are extended back to a neutral supine position and abduction is tested. Hip arthritis most often causes limitations with internal rotation and extension, usually in association with pain in the inguinal area. Palpation of the knee assesses for warmth, a common finding in knee arthritis, synovial swelling, or an effusion. Applying pressure in the suprapatellar area with 1 hand while palpating on either side of the patella with the other allows for the detection of effusions more readily because this forces excessive joint fluid that has accumulated in the suprapatellar area into the synovial space. This is done by milking the medial and lateral depressions around the patella superiorly in an effort to push the fluid into the suprapatellar space and then gently pushing either medially or laterally just superior to the patella. This releases the fluid back into the synovial space, causing the area medial to the patella to bulge out. The popliteal fossa should be palpated, because fluid within the knee joint tends to track posteriorly as it accumulates, producing fullness in the popliteal fossa and sometimes a frank cyst, identical to the Baker cysts seen in adults with rheumatoid arthritis. Palpating around the edges of the patella causes pain in many adolescents with patellofemoral syndrome (also known as chondromalacia patellae), a common cause of knee pain in active adolescents. In another maneuver that elicits pain in this syndrome, the patient relaxes the quadriceps muscles while the examiner pushes the patella inferiorly. While the examiner maintains pressure on the patella, the patient contracts the quadriceps. The tibial tubercle and patellar tendon should be inspected and palpated for swelling and tenderness associated with Osgood-Schlatter disease and patellar tendonitis, respectively. Most young children can touch their heel to their buttocks and hyperextend the knee. The examiner can detect subtle limitations in extension by standing at the foot of the table and lifting the heels of the child off the table as the child holds his or her legs fully extended. If 1 knee is limited with extension, the patella on that side may be slightly more elevated. Swelling in the ankles is often best seen when inspecting and palpating the posterior aspect of the ankle, where fullness on either side of the Achilles tendon may be appreciated between the tendon and the malleoli. Testing range of motion in the ankle should include both the tibiotalar ankle joint and the subtalar talocalcaneal joint. Cupping the heel with 1 hand and using the other hand to grasp the forefoot allows the examiner to move the forefoot superiorly (dorsiflexion) and inferiorly (plantar flexion). The hand cupping the heel is rocked laterally and medially to check inversion and eversion associated with motion at the subtalar joint. Holding the heel firmly with a cupped hand and gently rotating the forefoot with the other hand tests the joints of the midfoot. The plantar fascia and the Achilles tendon are palpated, and any tenderness or swelling is noted. The sacroiliac joints are palpated, any tenderness is noted, and the child is asked to keep the knees extended and bend forward, touching the hands to the ground if possible. The modified Schober measurement, which reveals whether the lumbar spine flexes normally, is done by marking the lumbar spine at a point where a horizontal line connecting the dimples of Venus intersects the spine. Then the examiner measures 10 cm above and 5 cm below that spot while the child is standing. When the child bends forward, the distance between the top and bottom marks should increase to at least 21 cm as the vertebral bodies separate during flexion. A shorter distance suggests limitation in mobility of the spine and potential spondylitis. Scoliosis is detected by noting any asymmetric elevation of the shoulder and upper back while the child bends forward. Hypermobility is a very common cause of pain associated with sports and other activities; it tends to improve with rest. Hypermobility, patellofemoral syndrome, frequent ankle sprains, and pes planus are frequently seen together. Myofascial pain syndromes are associated with the presence of trigger points, exquisitely tender, well-localized points often detected in the following locations: the occiput, trapezius muscles, medial borders of the scapula, upper outer quadrant of the buttocks, the 2nd cervical space anteriorly, the 2nd costochondral space just distal to the lateral epicondyle on the forearm, the greater trochanter in the proximal leg, and the medial aspects of the knees. Their presence in the older child with diffuse pain, fatigue, and difficulty sleeping is highly suggestive of a myofascial pain syndrome. Neck flexor weakness is common in dermatomyositis and polymyositis and is tested by having the child lie supine and lift only his or her head. To test proximal leg strength, the child rises from a sitting position on the floor. Chronic knee arthritis or hip disease leads to atrophy of the ipsilateral quadriceps. Similarly, ankle arthritis causes the gastrocnemius to atrophy; wrist arthritis leads to wasting of the forearm muscles; and elbow contractures cause atrophy of the triceps muscle. Atrophy is easily overlooked, and it is sometimes helpful to measure the circumference of the thigh, calf, or upper arm to detect asymmetry. The skin and mucous membranes should be examined carefully, as there may be clues to the presence of systemic disease (Table 33. Thickening and tightening of the skin, particularly over the distal extremities and face, are often present in scleroderma. It is not sensitive enough or specific enough to be diagnostically helpful for other diseases. The presence of peripheral or periorbital edema increases the suspicion of glomerulonephritis. Laboratory Studies Laboratory testing should be considered when the diagnosis is unclear or when there is a suspicion of life- or limb-threatening disease such as leukemia, septic arthritis, or osteomyelitis. However, if arthritis is detected on physical examination, laboratory testing aids in classifying the specific type of arthritis that is present.

Complement deficiency may be found in 40% of patients presenting with recurrent neisserial infections arthritis pain groin cheap etodolac 200mg on-line, particularly with meningococcal disease caused by uncommon serogroups (see Table 41 arthritis patient diet chart discount etodolac 400mg with visa. C1 inhibitor deficiency causes hereditary angioedema arthritis drugs etodolac 400 mg sale, an autosomal dominant disorder that results in dysregulation of the classical complement pathway. After minor trauma, affected patients develop local angioedema without urticaria, pain, or erythema. The angioedema may be severe and untreated leads to significant morbidity and mortality. Angioedema involving the larynx or upper airways can be life-threatening, and involvement of the bowel leads to abdominal pain, vomiting, and diarrhea. Lack of inhibition of plasma kallikrein by C1 inhibitor and dysregulated production of bradykinin is the cause of the angioedema. Treatment of hereditary angioedema includes administration of C1 inhibitor, administration of a pharmacologic inhibitor of plasma kallikrein (ecallantide), or administration of a bradykinin 2-antagonist (icatibant). During the critical 1st 2-4 hours after tissue invasion by pathogenic organisms, the arrival of phagocytic cells at the site of infection is crucial for the containment of the infection, limiting the size of the local lesion, and preventing dissemination. Neutrophils develop in the bone marrow from hematopoietic stem cells, and upon leaving the bone marrow mature neutrophils are found in the circulation or roll along the endothelium (known as the marginating pool). Adhesion molecules are necessary for neutrophils to roll and adhere to vascular endothelium and extravasate from the blood into sites of infection, where they phagocytose and kill pathogens, especially those coated by complement or antibodies. Once in tissues these cells ingest the offending organisms (phagocytosis), and activate biochemical pathways important in intracellular microbial killing (degranulation and oxidative metabolism). The respiratory burst consists of the de novo synthesis of highly toxic and often unstable derivatives of molecular oxygen. Degranulation is the process by which lysosomal granules, containing preformed polypeptide antibiotics and proteases, fuse with the phagocytic vacuoles containing the ingested microbes. Patients with neutrophil disorders are susceptible to a variety of bacterial infections and certain fungi. Infections associated with neutrophil disorders include infections of mucosal surfaces. Abnormal results of both tests indicate a deficiency in a terminal component common to both pathways (C3, C5-C9). Determination of C1 inhibitor levels and/or function is needed to definitively diagnose hereditary angioedema. At these levels, localized infections are more common than generalized bacteremia. In the cyclic form of neutropenia, there are periodic episodes of profound neutropenia (absolute neutrophil counts <200 cells/mm3), generally lasting 3-6 days and occurring in 21-day cycles (see Table 41. During the episodes of neutropenia, individuals develop aphthous ulcers, gingivitis, stomatitis, and cellulitis. Death from overwhelming infection with Clostridium perfringens occurs in about 10% of patients. Severe congenital neutropenia, which may be either persistent or cyclic, is also seen in Shwachman-Diamond syndrome, an autosomal recessive syndrome of pancreatic insufficiency accompanying bone marrow dysfunction. A gain-of-function mutation in the Wiskott-Aldrich syndrome protein has also been associated with an X-linked form of severe congenital neutropenia. Approximately 10% of patients with the diagnosis of severe congenital neutropenia and Shwachman-Diamond syndrome develop myelodysplasia/acute myelogenous leukemia. No cases of malignant transformations have been observed in patients with either cyclic or idiopathic neutropenia. Cutaneous, respiratory, gingival, and mucosal infections are common, and sepsis may lead to death in early childhood. Due to a failure of neutrophils to adhere normally to vascular endothelium (marginate), absolute neutrophil counts are usually greater than 20,000/mm3 even when patients are not infected. Depressed neutrophil chemotaxis has been observed in a wide variety of clinical conditions (see Table 41. Affected patients may have recurrent lymphadenitis, bacterial hepatic abscesses, or osteomyelitis. Infections also occur in the lungs, the middle ear, gastrointestinal tract, skin, and urinary tract. Patients characteristically exhibit lymphadenopathy, hypergammaglobulinemia, hepatosplenomegaly, dermatitis, failure to thrive, anemia, chronic diarrhea, and abscesses. Granulomas are prominent and may obstruct the pylorus or ureters or lead to inflammatory bowel disease. The mother produces antibodies to specific neutrophil antigens on the surface of fetal leukocytes that are inherited from the father and are not present on maternal cells. Isoimmune neonatal neutropenia, similar to isoimmune anemia and thrombocytopenia, is a transient process that resolves as maternal antibodies wane. Early treatment of infection while the infant is neutropenic is the major goal of therapy. Diminished or absent surface expression of these proteins accounts for a profound impairment of neutrophil and monocyte cell migration and phagocytosis. Steroids and antibiotics are used to treat granulomatous complications of the gastrointestinal, urinary, and respiratory tracts. Large azurophilic lysosomal granules are present in all granule-bearing cells including neutrophils and melanocytes. Recurrent infections affect the skin, respiratory tract, and mucous membranes and are caused by both gram-positive and gram-negative bacteria as well as by fungi. Most patients progress to an accelerated phase associated with EpsteinBarr virus infection and characterized by a lymphoproliferative syndrome with generalized lymphohistiocytic infiltrates, fever, jaundice, hepatomegaly, lymphadenopathy, and pancytopenia (see Table 41. Unexpectedly, these patients are also susceptible to skin and, rarely, invasive infections with Candida albicans. The arthritis is typically monoarticular, and aspirates of affected joints are sterile with a predominance of neutrophils. Daily colchicine prophylaxis prevents many of the long-term complications of this disorder. The spleen is also an important location for the phagocytosis of complement and antibody opsonized bacteria, and a key location for the production of antibodies. Functional asplenia occurs in children with sickle cell disease, initially as a result of vascular occlusion by the sickle cells in the splenic circulation. Congenital absence of the spleen may occur alone or as part of an asplenia syndrome with congenital heart disease. Individuals without spleens (anatomic or functional) are subject to a severe form of sepsis that is rapid in onset and can lead to sudden death if it is not recognized and treated promptly. Pneumococci are responsible for more than 50% of such infections; infections with H. The diagnosis of anatomic or functional asplenia is suggested by the presence of red blood cell inclusions, particularly Howell-Jolly bodies on peripheral blood smear. Lack of a spleen by ultrasonography of the abdomen is suggestive of asplenia, but accessory splenic tissue may still be present. The risk of fulminant infection in patients who have undergone splenectomy (from surgery or trauma), or in those with functional asplenia or congenital asplenia is highest in the 1st few years. The risk is lower in older children and in adults, probably because they have developed opsonizing antibodies through previous exposure. When splenectomy becomes necessary, partial protection against life-threatening infections can be obtained by immunizing patients with conjugated and polyvalent pneumococcal, H. Prophylactic antibiotics may be given continuously in a single daily dose for 1-3 years or up to the age of 16 years (some authorities suggest longer periods or even for life) after splenectomy. Parents of older asplenic children are advised to have their children seen by a physician or to administer the antibiotics at the 1st sign of a febrile illness. The episodes of arthritis are the most common presentation, start in early childhood, and typically affect 1-3 joints at a time. Treatment of the arthritis with surgical drainage, or treatment with intraarticular or systemic steroids has shown benefit in resolving arthritis. Although the rash can have some visual features of urticaria, it lacks angioedema or signs of mast cell degranulation, and is histologically characterized by a neutrophilic infiltrate. Neurologic symptoms, such as aseptic meningitis, headache, cerebral atrophy, uveitis, hearing loss, and intellectual disability, are common and severe. Autoinflammatory disorders present with spontaneous, episodic, or persistent inflammation, but without the development of autoantibodies or autoreactive lymphocytes. Autoinflammatory disorders were formerly known as periodic fever syndromes, but this term has fallen out of favor since fever is a frequent but not universal finding. Laboratory abnormalities typically normalize in days, and the rash responds rapidly. These episodes may last 4-7 days and are often triggered by stress, trauma, or vaccination. The lacunar strokes begin before the age of 5 years and typically occur during inflammatory episodes. A livedo-like rash is a prominent feature with biopsies showing a predominance of neutrophils and macrophages as well as vasculitis in medium-sized vessels. Blau syndrome was originally described as a granulomatous disease affecting the skin, joints, and uveal tract, and should be considered in any individual presenting with early-onset sarcoidosis. Blau syndrome presents with a boggy synovitis of large joints, particularly the wrist and ankles, and an erythematous papular rash similar to erythema nodosum. Unlike sarcoidosis, respiratory involvement and hilar adenopathy are rare, although granulomatous liver disease, cranial neuropathies, and large vessel vasculitis can occur. Most patients with Blau syndrome have been treated with corticosteroids, although limited reports have shown effectiveness of infliximab, thalidomide, and possibly anakinra. All patients develop cutaneous pustulosis, and biopsies of the skin lesions revealed a neutrophilic predominance. Respiratory distress, aphthous ulcers, hepatomegaly, and failure to thrive occurred, with approximately one-third of infants expiring prior to effective treatment. Bone is prominently involved, with osteopenia, multiple osteolytic lesions, and rib widening. A migratory rash with underlying fascial inflammation and myalgia can be seen, as well as conjunctivitis and periorbital edema. Abnormalities of immune regulation are frequently important components of the clinical manifestations in patients with primary immune deficiencies, which have been described previously in this chapter. Unlike autoinflammatory disorders, these disorders are not episodic and are associated with autoimmune manifestations. Additionally, the clinical phenotype includes varying degrees of susceptibility to infection. This disorder is fatal if not treated aggressively with combined immunosuppressive medications and chemotherapy. These infants also suffer from autoimmune diseases such as autoimmune thrombocytopenia and hemolytic anemia, eczema, and arthritis. Null mutations or point mutations that encode a nonfunctional protein can result in haploinsufficiency. The most common clinical manifestations include enteropathy; granulomatous and lymphocytic lung infiltration; lymphocytic infiltration of the bone marrow, brain, kidney, or liver; respiratory tract infections; splenomegaly; lymphadenopathy; and immune cytopenias. Patients frequently have hypogammaglobulinemia, which explains their propensity to infection. Hypomorphic mutations in Foxp3 that encode a protein with residual functional activity lead to a later onset and milder clinical phenotoype, but allergic disease and failure to thrive are common. Patients with this disorder are aggressively immunosuppressed to be stabilized, but bone marrow transplantation is the only curative therapy. Other autoimmune disorders, such as vitiligo, thyroiditis, and pernicious anemia may occur. The insidious and variable onset of the endocrinopathies requires the need for frequent evaluation for autoimmune endocrine disorders. The child continues to grow and develop normally, and his or her activities are not restricted. Red flags to consider disorders of the immune system include absent lymphoid tissue, failure to thrive, digital clubbing, chronic diarrhea, prolonged infections, infections with unusual organisms, repeated serious infections, eczematous dermatitis, a family history of early childhood deaths (presumably from infection), and other diseases associated with increased risks for infection (sickle cell anemia, malignancy, asplenia). In these cases, immunologic workup, genetic testing, and consultation with a clinical immunologist can lead to a diagnosis and definitive treatment.

Granulomatous-lymphocytic lung disease shortens survival in common variable immunodeficiency. The interleukin-12/interleukin12-receptor system: Role in normal and pathologic immune responses. Phosphoinositide 3-kinase delta gene mutation predisposes to respiratory infection and airway damage. Puberty is the time when there is an increase in sex steroid production, resulting in physical changes such as breast development in girls and testicular enlargement in boys, as well as maturation of processes required for future fertility. Puberty, also known as adolescence, is the time when children make the transition to adult patterns of behavior, which involve maturity, responsibility, and sexuality. Sex steroids also exert a negative feedback effect on the pituitary gland and hypothalamus. Physiology Perinatal Period and Infancy Maternal estrogens stimulate breast development in both male and female fetuses. Maternal estrogens also stimulate uterine developmental and endometrial growth; at birth, withdrawal of the high levels of maternal estrogen and placental progesterone causes the infant endometrium to regress or even slough and manifests as vaginal bleeding. Estrogen-induced vaginal cornification is generally evident as abundant vaginal discharge at birth and is maintained as long as estrogens are produced. Bone age refers to the degree of epiphyseal calcification, width, and proximity to adjacent metaphyses and is a marker of physical maturity that normally corresponds to chronologic age.
