Infants of mothers with first pregnancies can be affected, and there is a high recurrence risk. Both mother and father should have the common platelet alloantigens typed for incompatibility, and the mother should be tested for IgG antiplatelet antibodies recognizing that difference. Infants should receive washed maternal platelets, antigen-matched platelets, or in exceptionally dire circumstances, untyped platelets. Under investigation is whether prenatal platelet typing is of benefit in prevention of the substantial proportion of cases in first pregnancies. A high platelet count in most children does not appear to be a cause of significant morbidity because it is often transient. In some centers, aspirin in doses of 81 mg daily are administered when the platelet count exceeds 1. The early introduction of aspirin therapy may be more important if the patient has other problems that might contribute to hyperviscosity, such as a high white blood cell count or hemoglobin level. Denton A, Davis P: Extreme thrombocytosis in admissions to paediatric intensive care: no requirement for treatment, Arch Dis Child 92:515–516, 2007. On the b chain, valine is substituted for glutamic acid at position 6 on chromosome 11. As the amount of fetal hemoglobin decreases after age 3 to 6 months, patients with sickle cell disease are increasingly likely to experience their first clinical manifestations. What are the two major pathophysiologic mechanisms in sickle cell anemia that cause the morbidities associated with the disease Long-term hemolysis has been associated with pulmonary hypertension and right-sided heart failure. The adhesion of sickled erythrocytes to inflamed vascular endothelium is a principal pathologic component. Activation of leukocytes and platelets, as well as components of the coagulation protein cascade, is also prominent. This common early manifestation of sickling disorders in infants and young children is characterized by painful swelling of the hands, feet, and proximal fingers and toes caused by symmetrical infarction in the Figure 9-5. It may begin as early as 5 or 6 months of age, and it may precede the presence of Howell-Jolly bodies in the peripheral smear. Clinical experience indicates that the period of increased risk for serious bacterial infection parallels the development of functional asplenia. Consequently, in addition to routine vaccinations, antibiotic prophylaxis with penicillin is recommended beginning at 2 months of age. What are the three main categories of crises in patients with sickle cell disease Splenic dysfunction causes increased susceptibility to meningitis and sepsis (particularly pneumococcal). For outpatients with an acute painful crisis, ibuprofen or acetaminophen and codeine are reasonable choices. Patients with intensely painful crises require day unit or inpatient hospitalization for opioid (including morphine and meperidine) analgesics, ideally given intravenously. Patient-controlled analgesia offers the dual benefit of a constant infusion and intermittent boluses of an analgesic. For severe crises, blood transfusions to reduce the percentage of sickle cells to less than 30% may be beneficial. Jacob E, Miaskowski C, Savedra M, et al: Management of vaso-occlusive pain in children with sickle cell disease, J Pediatr Hematol Oncol 25:307–311, 2003. Acute sequestration crisis represents a true emergency in sickle cell disease and is the second leading cause of death in young children with sickle cell disease. The clinical problem is primarily one of hypovolemic shock as a result of the pooling of blood in the acutely enlarged spleen. The major therapeutic effort should be directed toward volume replacement with whatever fluid is handy. In most instances, normal saline or colloid solutions will be adequate until properly cross-matched blood is available. Acute sequestration crisis is one of the few instances for patients with sickle cell disease in which transfusion with whole blood is appropriate because the problem is one of hypovolemia and anemia rather than anemia alone. Rib and other bone infarcts can also occur, and hypoventilation may result from chest splinting. Pulmonary fat embolism has been seen to occur, particularly in the setting of a preceding bony painful crisis. Priapism is an unwanted, painful erection that is usually unrelated to sexual activity. It is an underappreciated morbidity in adolescents with sickle cell disease, usually occurring at least once by the age of 20 years and typically by the age of 12 years. Most patients are unaware of the term and the consequences; early intervention may prevent irreversible penile fibrosis and impotence. The risk for serious bacterial infection is increased among these patients as a result of functional asplenia. What are the approaches to the prevention of stroke in children with sickle cell disease Children should undergo transcranial Doppler ultrasound measurements of intracranial arterial blood flow velocity. What is the primary mechanism by which hydroxyurea is beneficial for sickle cell disease Hydroxyurea is a cytoxic drug that had been used primarily to treat chronic myelogenous leukemia and polycythemia vera. Increased concentrations of HbF (particularly >20%) is associated with fewer vaso-occlusive painful events, transfusions, and hospitalizations. Heterozygosity for the sickle gene occurs in about 8% of blacks in the United States, 3% of Hispanics in the eastern United States, and a much smaller percentage of individuals of Italian, Greek, Arabic, and Veddah Indian heritage. Portions of the kidney may have physiologically low oxygen concentrations that can interfere with function and lead to an inability to concentrate urine (hyposthenuria) and hematuria (usually microscopic and asymptomatic). This variant is particularly high in the southeast Asian population (especially those of Laotian, Thai, and Cambodian heritage). The most common abnormal findings on a peripheral smear are microcytosis and target cells. The thalassemias are a heterogeneous group of disorders of hereditary anemia due to diminished or absent normal globin chain production. Depending on the number of genes that are deleted, the production of polypeptide chains is diminished. In patients with a-thalassemia, a-globin production is lowered; in patients with b-thalassemia, b-globin production is lowered. When one class of polypeptide chains is diminished, this leads to a relative excess of the other chain. Despite its incidence being highest in the Mediterranean region, b-thalassemia was first described by a hematologist, Dr. Speculation is that the condition was thought to be malaria, endemic to that region and with similar clinical features of hemolysis, anemia, and splenomegaly. Clinical heterogeneity results from variability in the number of gene deletions (particularly in a-thalassemia). A large number of point mutations have been identified in various populations; this can contribute to the phenotypic diversity. Homozygous b-thalassemia is detected by the absence (b0) or reduction (b) of the amount of HbA (a2 b2) relative to HbF (a2 g2 or fetal hemoglobin) on hemoglobin electrophoresis. The carrier state for b-thalassemia is characterized by a low mean cell volume and, in most instances, an increased level of HbA2 (a2 d2) or HbF. The levels of these two hemoglobins are most accurately measured by column chromatography. Estimation or quantitation from electrophoretic patterns is frequently misleading. The a-thalassemia trait remains a diagnosis of exclusion (low mean cell volume in the absence of an identifiable cause) in the clinical laboratory, although the enumeration of missing a genes for the most common deletions in specific ethnic populations is accomplished by molecular techniques. When all four a-globin genes are missing or nonfunctional, this results in severe intrauterine anemia and hydrops fetalis. How can coexistent iron deficiency increase the difficulty of diagnosing b-thalassemia

The esthetic shortcom that the monolateral fixator systems such as »Orthofix« or 566 4. But it is precisely the low mechanical produced by modifying the length of the telescopic rods. If monolateral fixators are to be used, it is more lengthening of the telescopic rods required to correct the appropriate to use those that can readily be dynamized, deformity. An excessively rigid system central control facility where the corrections are calcu prevents new bone formation. Three different types of strategies are possible: Our standard device for lengthening with complex the apparatus is fitted conventionally and then ad corrections is the »Taylor Spatial Frame« [10] ( The basic system consists the apparatus is fitted in the corrected position and of two rings (or part rings) and six telescopic rods with gradually straightened during the continuous correc tion. In order to shorten the application period of the fixator, and thus the associated handicap, we replace the frame after the desired length has been achieved and callus has started to form with a specially produced Tomofix plate. This plate has fixed-angle screws, does not lie completely flush against the periosteum (and does not therefore impair the circulation) and has a relatively high intrinsic elasticity (thereby promoting callus formation). Complications Surgical leg lengthening and deformity correction are pro tracted, unpleasant treatments that are demanding for all involved and full of complications. Parents and child must be fully briefed accordingly before the start of treatment. Reputable studies have shown that every patient suffers one fairly major complication on average [7, 12, 20, 21, 32, 38]. For the femoral orthopaedists like to differentiate between »complications«, lengthening we use a monolateral fixator with a hinge (arrow), which »problems« and »obstacles« [32]. We do not consider these allows continuous axial correction euphemistic terms to be particularly useful and therefore Fig. Photograph of the Taylor Spatial Frame on the lower leg of a 15 year old boy with achondroplasia and varus deformity of the lower leg and excessively long fibula with shortening of the tibia 567 4 4. Major complica tions are those that require an unscheduled operation, whereas minor complications can be solved without an operation. The principal complications are as follows: Superficial infections at the entry points of the Kirsch ner wires or screws. Such infections occur in almost all patients and can be treated by corresponding care, bathing and occasionally by antibiotic administration or a small incision. The entry points must not only be disinfected every day, it is also important that the chil dren take regular baths. Soaking in water helps avoid crust formation and the retention of bacteria with consequent infection. Far from constituting an infec tion hazard, the bath water actually helps avoid infec tions. The nail entry points must also be adequately cleaned mechanically, since the disinfectant on its own is ineffective. If it occurs during lower leg lengthening there is a risk of an increasing equinus foot position. This tendency can be counteracted with physiotherapy, splints and ban dages (Fig. If neighboring joints are particu larly at risk they must be included in the assembly Fig. Angulation corrections also involve cur especially if those joints are at risk, i.
