Girls were found to have a larger capacity than boys blood pressure chart pictures purchase lanoxin no prescription, but the rate of increase with age was not significantly different between them. Data obtained from the International Reflux Study indicate that there is not a linear relation between age and capacity and that there is a huge variability (Figure 3). Kaefer and co-workers demonstrated that a non-linear model was the most accurate for the relation between By age 12, the daily pattern of voiding includes 4-6 age and bladder capacity, and they determined two voids per day [17]. Grade of recommendation: B As in adults, flow rates are clearly dependent upon voided volume, and normal values can only be applied Many signs and symptoms related to voiding and to flow rates that have been registered when voiding wetting are new to the parents, and they should be at a bladder volume approximating the normal capacity specifically asked for, using the questionnaire as for age [18,21]. If possible the child should be addressed as the patient and questioned directly, as the symptoms prompting the parents to seek consultation may be different from those are problematic for the child. Checklists and frequency volume chart can be filled out at home, Even with clear definitions, the approach to historyand checked at the first visit to the clinics. Also, the general history-taking should include questions sociocultural aspects and psychomotor development relevant to familial disorders, neurological and will distort the presentation. Validated questionnaires congenital abnormalities, as well as information on are very helpful in structuring the history-taking; they previous urinary infections, relevant surgery and at least provide checklists [1]. Information should be obtained on monosymptomatic nocturnal enuresis can be made medication with known or possible effects on the lower with confidence. This is important in view of the potential these conditions have to cause irreversible loss of kidney Level of evidence: 4. Asymmetry of buttocks, legs or feet, as well In order to be comprehensive, physical examination as other signs of occult neurospinal dysraphism in should include urinalysis to identify patients with the lumbosacral area (subcutaneous lipoma, skin urinary tract infection, diabetes mellitus, diabetes discoloration, hair growth and abnormal gait) should insipidus and hypercalciuria if indicated [9]. In pelvic floor relaxation and obstructing the free flow of order to obtain a complete picture, defecation urine [8] (Figure 4). Grade of recommendation: D Then, this becomes termed as bladder-bowel diary due to its complexity. Whenever possible, filling out the chart is the responsibility of the child: the parents provide assistance and support. Ideally the chart should cover 3 complete days, but in reality completion over a weekend restricts the record to 2 days. The frequency volume chart is a reliable non-invasive measure of maximum bladder storage capacity and can be used as an outcome measure in children with bladder dysfunction if care is taken to minimise confounding factors and sources of error during chart completion [10]. Children with bladder symptoms void smaller volumes of urine than may be expected from traditional estimates [10]. Figure 4: Improper position for voiding: the feet are this is unrelated to either gender, type of presenting not supported (unbalanced position) and the body is bent forward. Support of the feet will correct this incontinence or a positive family history of bladder and will allow the pelvic floor muscles to relax dysfunction. Data in normal children and children without constipation the mean diameter was in children with different categories of incontinence are 2,4 and 2,1 cm in two different studies respectively [23available for comparison [10-12]. In children with constipation the rectal diameter was on average 3,4 cm in one and 4,9 in the second In order to obtain a complete picture it is better to ask study. Both studies do not mention specificity nor for a bladder diary: fluid intake as well as voiding sensitivity. Finding a dilated and filled rectum on frequency, voided volumes, incontinence episodes ultrasound while the child feels no need to defecate and defecation frequency and/or soiling are recorded. Test/retest evaluation is not available; trend analyses Overt constipation should be dealt with before of frequency/volume charts can be extracted from embarking on treatment of incontinence or detrusor currently available data. For objective children with the exception of monosymptomatic grading, 12-hour pad test and frequency/volume charts bedwetting where voiding, as far as we know, is are validated instruments [12-14]. In children, the 12-hour pad test should also give Graphic registration of the urinary flow rate during information about fluid intake. Flow patterns complementary to the bladder diary, which denotes and rates should be repeated to allow for evaluation, more the frequency of incontinence and the distribution and several recordings are needed to obtain of wetting episodes than the quantities of urine lost. The amount of urine lost during sleep can be deterApproximately 1% of school children have a voiding mined by weighing diapers or absorbent pads, before that can be labelled abnormal with flattened or and after sleep. The remaining 99% have a nocturnal urine output, the volume of the early-morning bell-shaped flow curve [27]. It should be noted that a voiding should be added to the amount lost during normal flow does not exclude a voiding disturbance, sleep. Specific scores correlated with lower urinary tract dysfunction with a Flow recordings with a voided volume of less than specificity and sensitivity of about 90% [15,16]. If the bladder is still nearly empty the child should be asked to drink some water until the bladder Level of evidence: 3. An intermittent flow pattern [17-19] Reproducibility seems to be best using the shows a interrupted flow, whereas in fluctuating voiding method described by Leech [20-22]. A better way to match clues from the medical history with signs and symptoms is the measurement of Measurement of urinary flow is performed as a solitary colonic transit time. In measuring flow time, the time intervals In most clinical settings, ultrasound-imaging techniques between flow episodes are disregarded. Grade of recommendation: B can be readily detected, but detection of the more subtle expressions of these abnormalities require urological expertise on the part of the ultrasound operator [33]. Lower urinary tract abnormalities are even more difficult to assess for the inexperienced, aside from bladder wall thickness: a bladder wall cross-section of more than 3-4 millimetres, measured at 50% of expected bladder capacity, is suspicious of detrusor overactivity [34,35]. Because only a few studies have been conducted to compare bladder wall thickness in normal children without complaints and in children with lower urinary tract dysfunction, more studies need to be performed to validate these non-invasive techniques [36, 37]. Another possibility is to assess bladder volume and bladder wall thickness to calculate the Bladder Volume / Bladder Wall Thickness index. In children with nocturnal enuresis this index correlated well with response to treatment [38]. The identification or exclusion of post-void residual is therefore an integral part of the study of micturition. However, an uneasy child voiding in unfamiliar Figure 6: flow curve of 2 children with a static, Figure 7: intermittent flow curve in a child with anatomic obstruction; the curve is continuous but disco-ordination between detrusor contraction the flow is lower than normal and extended in time. Urinary flow may voiding on command with a partially filled or registration will detect the plateau-shaped flow curve overfilled bladder. This is of particular importance if the patient A clinically significant post-void residual on repeated is in a diuretic phase. In patients with gross occasions clearly points to incomplete bladder vesicoureteral reflux, urine from the ureters may enter emptying. The pad test will detect the cases with the bladder immediately after micturition and may obvious stress and urgency incontinence, or falsely be interpreted as residual urine. Ultrasound imaging will raise of residual urine is an observation of clinical value, but suspicion of an ectopic ureter. An In short, invasive diagnostics are indicated when the isolated finding of residual urine requires confirmation non-invasive testing raises suspicion of neurogenic before being considered significant, especially in detrusor-sphincter dysfunction (occult spinal infants and young children. With ultrasound, bladder filling is assessed and when the To diagnose the complex of non-neurogenic bladder capacity is equal to the functional or expected detrusor-sphincter dysfunction, recurrent urinary bladder capacity for age, the child is asked to void into tract infections and vesicoureteral reflux, urodythe flowmeter.

If the shift between men and the other Non-pregnant women <120 g/L groups is bigger than in a standard reference group it indicates that the iron supply is not enough for Pregnant women <110 g/L young children and women, who have a relative higher requirement than men (2). Another solution is Currently the most important indicator for the to measure an indicator like sTfR, which is less iron status is the measurement of ferritin. Until now there are no plasma content correlates well with the iron clear cut off values for ferritin but they usually stores, and in the first stage of iron deficiency the range between 10 and 30 mg/L. A ferritin value concentration of ferritin already decreases, which below 10 mg/L certainly shows iron deficiency. Low ferBecause of its common use the cost for ferritin ritin always indicates storage iron depletion. The cost of the chemicals for immunovalue is not inevitably a sign of a good iron status. By including a standard parameters for acute and chronic infection, to disclinical chemistry control, which usually has valcover subjects in which the ferritin concentration ues for ferritin in different concentrations, it is might be increased by infection.

The lowest ferritin concenthe hematocrit usually correlates well with Hb, tration in the clinical controls is also mostly relabut is even less sensitive for iron deficiency than tively high (around five times more than the cut Hb. Therefore it is not a very helpful indicator in off value) which can make the calculation of the diagnosis of nutritional anemia. The sTfR is released from the cells into the and a reduced size of the erythrocytes indicate iron blood stream depending on the iron requirements. A large number of clinical disorders affect of iron deficiency, after the iron stores are exthe transferrin saturation (1) and plasma iron has a hausted and the Hb concentration is still above the marked diurnal variation. Therefore ferritin/sTfR are usually the correlate very well it is relatively easy to get the more useful indicators under these circumstances. It is a very simthe calculation of the iron stores in mg/kg body ple and robust measurement and can be useful in weight similar to the results of bone marrow screening for iron deficiency (5). If this is not corrected it can have significant influence on the detection of anemia prevalence (8), especially when a large number of subjects Dried blood spots have Hb values around the cut off value. The best solution would is to centrifuge the sample and to measure ferritin be to have a robust method in the field to measure in dried plasma spots (9, 10). Therefore strict ples on filter paper can be an alternative rules have to be followed (good drying overnight (Figures 4.

It is characterized by idiosyncratic response, with nocturia of equivalent severity producing very different effects on quality of life for different people. Speed of progression of nocturia is likely to influence propensity to present for medical consultation; implicitly, slower progression will enable coping adaptations that ameliorate bother, the latter being the ultimate arbiter of whether medical opinion is sought. Speed of progression is difficult to capture, as are other crucial influences, such as contextual environmental influence, personality trait, and coping strategies, and thus the complex interplay between severity and bother remains unclear. Day-by-day variation, habitual differences between work and non-work days, and temporal fluctuation over extended time periods hamper the reliable capture of a severity score. The terminology needs to not only be straightforward and manageable, but also deal with varied circumstances, such as shift workers (for whom nocturia may be a daytime event). Furthermore, the medical priority accorded to nocturia does not reflect the potential seriousness of possible underlying conditions. Many physicians disregard nocturia occurring on average once per night, stating that it does not bother the patient or represent a health risk. This is probably a mistake, as it is a state that has progressed from no nocturia, and may continue to progress to bother the patient subsequently. Thus, nocturia once per night might represent an opportunity for screening and instigation of measures to prevent progression to bothersome nocturia. There is merit to ascertaining severity thresholds above which nocturia becomes clinically significant or below Nocturia 139 which adequate therapeutic benefit can be claimed. However, it is essential that these are defined for specific populations and not extrapolated to all patients. For example, a threshold value for a healthy working person is likely to differ from that of a healthy older person or someone with neurological disease where multiple causes of sleep disturbance may be present. Even with the greater strength of proper assessment, inability to capture the issues alluded to above mandates caution in interpreting results. The extensive evidence base concerning nocturia is reflected in this chapter, but much of it fails to meet contemporary standards for high-quality evidence. When some of the interventions are potentially morbid, a strong case for their use is needed; without scientifically rigorous evaluation, such interventions should be avoided. The symptom of nocturia is the complaint that the individual has to wake at night one or more times to void. This definition does not include any reference to bother; many physicians regard nocturia once per night as not being clinically significant. However, some people can be substantially bothered by nocturia once per night, and the potential for symptom progression or a serious underlying medical condition means that a single episode of nocturia per night may have more importance than it is often given credit for. Nocturnal enuresis signifies voiding while remaining asleep and, technically, should be considered part of the nocturnal voided volume, though difficult to quantify in practice. The terminology in current use necessarily involves some compromise (8,9), and the area is one in which debate and consensus is ongoing. In general, the definition of a condition is a crucial factor in the evaluation of its epidemiology; nocturia is no exception (13). However, it has been suggested that if the definition needs to address the issue of sleep following the void, it may be the intention of going back to sleep after voiding which might be more clinically relevant (16).

Executive summary of recommendations Prepregnancy counselling Women with red cell antibodies, particularly if there is a risk of fetal anaemia or if compatible donor red cells for transfusion may be difficult to obtain, should attend for prepregnancy counselling with a P clinician with knowledge and expertise of this condition. Red cell antibodies in pregnancy What red cell antibodies are clinically significant (maternal and fetal) during pregnancyfi All women should have their blood group and antibody status determined at booking and at 28 weeks D of gestation (Appendix 2). Clinicians should be aware that severe fetal anaemia can result in hydrops which significantly worsens D the perinatal outcome. Non-invasive fetal genotyping using maternal blood is now possible for D, C, c, E, e and K antigens. This C should be performed in the first instance for the relevant antigen when maternal red cell antibodies are present. P Anti-D prophylaxis should be given to cover invasive testing if the mother is rhesus D (RhD) negative D and is not sensitised. If the fetus is at risk of anaemia, when should referral to a fetal medicine specialist take placefi What thresholds should be used for the various antibodies that could cause fetal anaemia to trigger referral for further investigation or monitoringfi Referral for a fetal medicine opinion should therefore be made once anti-D levels are > 4 iu/ml. Referral for a fetal medicine opinion should therefore be made once anti-c levels are > 7. For anti-K antibodies, referral should take place once detected, as severe fetal anaemia can occur even with low titres. Anti-D and anti-c levels should be measured every 4 weeks up to 28 weeks of gestation and then every D 2 weeks until delivery. Although anti-K titres do not correlate well with either the development or severity of fetal anaemia, D titres should nevertheless be measured every 4 weeks up to 28 weeks of gestation, then every 2 weeks until delivery. For antibodies that could potentially cause problems with cross-matching or issues with the availability of appropriate blood, discussion with the blood transfusion service is required regarding the frequency P of antenatal testing. This may depend on the type of antibody as well as the likelihood of requiring blood at short notice. P If the fetus carries the corresponding antigen for a maternal antibody which is capable of causing fetal B anaemia and if the antibody levels/titres rise beyond the levels detailed in section 6. For antibodies other than anti-D, anti-c, anti-C, anti-E or anti-K, maternity staff should liaise with their local transfusion laboratory to assess and plan for any possible transfusion requirements, as obtaining P the relevant blood may take longer. How often should pregnant women with red cell antibodies who are at high risk of requiring a transfusion (placenta praevia, sickle cell disease etc. Pregnant women with red cell antibodies, who are assessed as being at high risk of requiring a blood transfusion, should have a cross-match sample taken at least every week. P If maternal transfusion is required, what type of donor blood or blood components should be usedfi Should RhD-negative women who have anti-D or non-anti-D antibodies receive routine antenatal or postnatal prophylaxisfi Anti-D immunoglobulin should be given to RhD-negative women with non-anti-D antibodies for routine B antenatal prophylaxis, for potential antenatal sensitising events and postnatal prophylaxis. D Discussion and liaison with the transfusion laboratory are essential in determining whether anti-D D antibodies are immune or passive in women who have previously received anti-D prophylaxis. Requirements for blood What are the logistics of obtaining blood or blood components for the woman, fetus or neonatefi Close collaboration between the maternity, neonatology and haematology staff is essential. P When blood is required for women with multiple antibodies or antibodies against high prevalence antigens, planning is required as rare blood donors may need to be called up to donate, or frozen blood P may need to be obtained from the National Frozen Blood Bank in Liverpool. What blood or blood components can be administered in the emergency situation to a woman known to have red cell antibodiesfi Timing of delivery for women with red cell antibodies that can cause fetal anaemia will depend on the antibody levels/titres, rate of rise as well as if any fetal therapy has been required. The mode, timing P and place of delivery are otherwise dependent on standard obstetric grounds. This depends on the risk of haemolysis or anaemia conferred by the relevant red cell antibody. The C neonate should have regular clinical assessment of its neurobehavioural state and be observed for the development of jaundice and/or anaemia. P the mother should be encouraged to feed the baby regularly to guard against dehydration, since dehydration can increase the severity of jaundice. P Clinicians should be aware that if bilirubin levels rise rapidly or above the interventional threshold, C phototherapy and/or exchange transfusion may be required. Pregnancies complicated by red cell alloimmunisation with a minimal or no risk of fetal or neonatal anaemia require no specific treatment. P Long-term consequences of red cell antibodies to women and their offspring What are the long-term health consequences for the womanfi P What are the long-term health concerns for the children of women with red cell antibodies during pregnancyfi Purpose and scope the purpose of this guideline is to provide guidance on the management of pregnant women with red cell antibodies predating the pregnancy or those developing antibodies during pregnancy. The guideline also includes the management of fetal anaemia caused by red cell antibodies, as well as the early management of the neonate at risk of anaemia and/or hyperbilirubinaemia. It does not address the management of the pregnant woman with anti-platelet antibodies or other autoimmune or alloimmune antibodies. Introduction and background epidemiology the presence of maternal red cell antibodies during pregnancy is a relatively common finding and requires close collaboration between the blood transfusion laboratory, obstetric and neonatal care providers. A population study from the Netherlands found that red cell antibodies were detected in 1. Some antibodies (including anti-D, anti-K (-Kell) and anti-c) confer significant fetal and neonatal risks such as anaemia requiring intrauterine or neonatal transfusion, jaundice or perinatal loss. There are many antibodies that are unlikely to significantly affect the fetus but can cause neonatal anaemia and hyperbilirubinaemia, while others may cause problems for the screening and provision of appropriate blood or blood components to the mother or fetus/neonate when required (Appendix 1).

Adapted from Skarin, Dana-Farber Cancer Institute Atlas of Diagnostic Oncology, 1991. Since Hodgkin lymphoma spreads in a nonrandom fashion, and since treatment is designed according to extent of disease, it is most important to know the extent of disease. Radiotherapy is delivered to known areas of disease and immediately adjacent nodebearing tissue, taking into account the tendency for contiguous spread of the disease. More advanced disease is treated with repeated cycles of combination chemotherapy. Children do as well as adults, although the disease is rare under 10 years of age. With the improvement in prognosis, less aggressive treatment regimens are now being studied in an attempt to decrease the amount of therapy given to patients with favorable prognosis and thereby avoid some of the long-term side effects of therapy. Classification the classification of lymphoma has changed over the years with a better understanding of the underlying biology of the disease. Some forms of low grade lymphoma exhibit such indolent behavior that patients are not typically treated unless the disease is causing symptoms. They generally exhibit relentless (and in some cases very rapid) progression and are fatal if untreated. However, in contrast to low grade lymphomas, many patients can be cured with treatment. Most high grade lymphomas occur in middle age or later, but some (Burkitt lymphoma, for example) occur with appreciable frequency in children and young adults. The most common indolent lymphoma is follicular lymphoma (a B-cell lymphoma) and the most common aggressive lymphoma is diffuse large B cell lymphoma. Pathogenesis When a B cell passes through the germinal center of a lymph node and undergoes somatic hypermutation and class switching, it is particularly vulnerable to malignant transformation. Many lymphomas are the result of chromosomal translocations involving various oncogenes and the promoter for the IgH gene on chromosome 14. The result is a rather indolent lymphoma characterized by slow accumulation of malignant cells in lymph nodes resulting in lymph node enlargement. The t(8;14) that characterizes Burkitt lymphoma places the c-myc oncogene (chromosome 8) under the control of the IgH promoter (Figure 9. Overexpression of cmyc creates a strong proliferation signal and so Burkitt lymphoma is a very aggressive malignancy with an extraordinary growth rate (tumor nodules may double in size in one day). The common t(8;14) and variant t(2;8) and t(8;22) chromosomes in Burkitt lymphoma. The normal chromosomes are illustrated on the left and the abnormal c-myc-bearing chromosomes on the right. The second abnormal chromosome produced by each translocation (which may contain nonfunctional fragments of c-myc or immunoglobulin genes) is not represented, nor is the normal chromosome of each pair, which does not participate in the translocation. New genetics of Burkitt lymphoma and other nonHodgkin lymphomas, Am J Med 77:1083). Other factors that may contribute to the pathogenesis of lymphomas in humans include chronic infection and immunosuppression. Individuals may also present with B symptoms, pain, organ failure, or a variety of other symptoms, depending upon the kind of lymphoma and the sites of involvement. Patients with indolent lymphoma are more likely to be asymptomatic at diagnosis than patients with aggressive lymphomas. More than two thirds of patients with B-cell lymphoma have disseminated disease at diagnosis. Many have extranodal disease, especially in the bone marrow and gastrointestinal tract. These abnormalities include Coombs-positive hemolytic anemia, immunoglobulin deficiency and monoclonal gammopathy. Diagnosis and staging An adequate sample of tissue is essential to establish the correct diagnosis. Distinguishing one lymphoma subtype from another requires a skilled pathologist using a combination of morphology, immunophenotyping, and occasionally molecular diagnostics. Fine needle aspiration may help distinguish lymph nodes enlarged by lymphoma versus metastatic carcinoma or reactive processes, but accurate subtyping and characterization of lymphomas requires excisional biopsy. Within this broad category, subclassification of the different types of B cell lymphoma relies on the morphology, architectural organization, immunophenotype, and in some cases, the specific genetic aberrations of the malignant cells. Previous pathologic classification schemes relied primarily on the size and shape of the malignant cells and the architecture of the infiltrate. Some B cell lymphomas are named for the resemblance between the malignant clonal cells and a normal counterpart (geographic locale in the lymph node, immunophenotype, or morphology), as in mantle cell lymphoma and marginal zone lymphoma. Generally speaking, the hematopathologist is assessing whether there are significant abnormalities in lymph node architecture (loss of the typical B and T cell zone pattern), aberrant locations or accumulations of B cells or T cells, or the presence of cells with atypical morphology. In some cases, it can be difficult to distinguish reactive and malignant conditions. As this rearrangement and use of specific V, D, and J cassettes is unique for every lymphocyte, a malignant lymphocyte population will show an aberrant monoclonality in this regard. Stage has a more important role in determining prognosis and treatment in Hodgkin lymphoma than in non-Hodgkin lymphoma. In some forms of indolent lymphoma, therapy can be postponed until the patient becomes symptomatic. Radiotherapy, either alone or in combination with chemotherapy, may help to palliate localized symptomatic disease. Non-Hodgkin lymphomas in children are typically aggressive cancers that have many features in common with acute lymphoblastic leukemia (discussed in chapter 8). An aggressive approach to the therapy of high grade lymphomas in children, using central nervous system treatment along with combination chemotherapy, has resulted in a remarkable improvement in the survival. Specific Diseases and Their Diagnosis In this final section, we will discuss a few representative lymphoid malignancies, and describe their presenting features and diagnostic strategies that separate them from benign/reactive conditions. Neoplastic In Chapters 1 and 8, we addressed the approach to high and low peripheral blood counts in the myeloid and erythroid lineages. One of the more common causes of reactive lymphocytosis conditions is acute infection with Epstein-Barr virus (infectious mononucleosis). Infectious mononucleosis presents with impressive symptoms and signs in young adults: fever, sore throat, profound fatigue, enlarged lymph nodes in the neck and axillae, rash, splenomegaly and, less often, hepatomegaly. Some of these clinical features also may be found in patients with cytomegalovirus and toxoplasma infections. More complicated manifestations such as splenic rupture, aseptic meningitis, respiratory distress as a result of enlarged tonsils, and severe hepatitis can be seen but are rare. Lymphocytosis with a preponderance of atypical lymphocytes is most frequently seen several days into the clinical illness. Elevation in liver enzymes is found in 80% of the cases, indicating mild hepatitis. In contrast, patients whose malignant clone shows little or no evidence of somatic hypermutation, presumably reflecting origin from a naive B cell, have a worse prognosis, with median survival in the 5-7 year range. By staining the blood, bone marrow, or lymph node sample with cocktails of antibodies against specific surface proteins that have different fluorescent dyes attached, the flow 186 cytometer can detect even relatively small clones with aberrant phenotypes. It can be confusing that in a disease we call chronic lymphocytic leukemia, patients very often exhibit lymphadenopathy and splenomegaly due to infiltration by leukemia cells. As is the case with other indolent lymphomas (particularly follicular center cell lymphoma), in a minority of cases transformation to a much more aggressive (and rarely curable) large cell lymphoma may occur. The presence of immature (blastic) lymphoid cells in the peripheral blood indicates acute lymphoblastic leukemia/lymphoma (Chapter 8), which can be confirmed and further subtyped as B cell or T cell type by flow cytometry.
