They found an increase in negative selfevaluation emotions medicine youth lyrics buy 100 mg thorazine with visa, such as sadness and anger medicine valley high school buy thorazine 100mg amex, following hair pulling medicine university buy discount thorazine 100 mg line. Though pulling may initially function to relieve negative emotions treatment uveitis purchase cheap thorazine on line, the return of negative emotions resulting from pulling medicine synonym thorazine 50 mg buy with mastercard. Walther However, findings are mixed, as Snorrason, Smári, and Ólafsson (2011) found higher levels of emotionbased impulsivity. Schuck, Keijsers, and Rinck (2012) found that those with skin picking are more likely than controls to distract themselves and avoid contact with photos of skin irregularities. Similarly, Lee, Franklin, Turkel, Goetz, and Woods (2012) compared the performance of individuals with and without hair pulling disorder on the exogenous cueing task, a computer task frequently used to measure reaction times to different stimuli. Participants view a picture cue followed by a target stimulus and are directed to immediately press a key based on where the target stimulus appeared on the screen. Reaction times were interpreted to reflect the degree to which the participant attended to the picture cues. Lee and colleagues (2012) found that adults with hair pulling were more likely than controls to exhibit enhanced attentional disengagement from photos related to hair. Furthermore, those with more severe hair pulling had greater difficulty disengaging attention from hairrelated cues. This is in contrast to patterns seen in anxiety disorders, which suggest that those with heightened anxiety attend to the threat cue and disengage attention quickly. The researchers suggested that these findings may reflect emotion regulation strategies. Attentional bias modification is a rapidly growing area of research that involves computerized paradigms designed to change interpretations about a problematic behavior in order to reduce the frequency of that behavior (Beard & Amir, 2008). Paradigms have recently been tested for anxiety (Steinman & Teachman, 2014), smoking cessation. Many studies have found a significant reduction in the targeted behavior or symptoms at posttreatment.

The behavior is associated with negative physical and psychological consequences and is a risk factor for attempted suicide (Asarnow et al. In addition, the chapter highlights factors to consider in treatment planning with clients engaging in the behavior. The Nature of the Problem Treatments of psychological conditions and behaviors should ideally be based on empirically validated models of their development and maintenance. In addition, existing models have not yet integrated recent research on biological factors that may play a significant role in the etiology of the Treatments for Psychological Problems and Syndromes, First Edition. Research has demonstrated that individuals experience a reduction in negative affect. In turn, the behavior is negatively reinforced as it allows escape from aversive affect. In fact, most research supports models that include affective negative reinforcement as a critical functional component of the behavior. Automatic functions are more frequently supported and endorsed by participants than social functions (Brown, Comtois, & Linehan, 2002; Heath, Ross, Toste, Charlebois, & Nedecheva, 2009; Klonsky & Muehlenkamp, 2007; Turner et al. A smaller, but substantial, proportion of individuals also endorse social functions of the behavior (Nock, 2008). However, findings such as these only provide support for components of the model and are largely correlational in nature. For example, components of the psychodynamically based interpersonal boundaries model, alongside affect regulation models, are fundamental in this developmental model (Yates, 2004). Future prospective longitudinal research may wish to focus on empirical validations of the proposed disrupted mechanisms following childhood trauma and their role as mediators in this association. These vulnerabilities lead to an inability to effectively respond to stressful life events. The behavior is maintained because of its efficacy and immediacy in serving these regulatory functions (Nock, 2009). The intervention, which incorporates cognitive behavioral techniques with a focus on emotion regulation, validation, and acceptance, consists of individual and group therapy, and telephone consultations for clients and case consultations for therapists (Linehan, 1993). Treatment generally lasts for at least one year, although modifications of the intervention have shortened the length of treatment. However, the distinction between suicidal and nonsuicidal selfinjury makes it 334 Emily H. Andover difficult to draw conclusions on one behavior based on analysis of the composite variable. Further, the chain analysis may provide a mechanism for emotional exposure in treatment, which may in turn reduce the shame associated with the behavior (Lynch et al. While a component analysis has not been conducted, the main treatment mechanism has theorized as the differential reinforcement of alternative behaviors. Without dismantling studies accounting for the specific mechanisms of positive treatment response. Therapists should be prepared to assess and to discuss this ambivalence with clients. As suggested by Muehlenkamp (2006), the formation of a Non-suicidal Self-injury 337 collaborative working relationship in which the client and the therapist address selfinjury as a team is paramount to successfully reducing the behavior. Specific therapeutic techniques may enhance or reduce the alliance between the client and therapist. Not immediately asking the client to stop selfinjuring does not, however, imply an acceptance of the behavior. Common cooccurring disorders include major depressive disorder, dysthymia, depressive disorder not otherwise specified, posttraumatic stress disorder. Further research is necessary to determine whether specific client or treatment characteristics that differentiate response to treatment solely focusing on cooccurring psychopathology can be identified.

These vary from single sclerotic lesions (seen in about half of patients) to > 3 lesions (in one third of patients) 1006 treatment 2014 discount thorazine 50mg visa. The neoplastic plasma cells are of IgG or IgA type medications qt prolongation thorazine 100 mg, and are lambda-re stricted in almost all cases 2d6 medications order 100mg thorazine fast delivery. No significant correla tions between genetic abnormalities and clinical features have been established 1924 treatment centers cheap thorazine 100mg overnight delivery. Patients with localized plasma cell tumours treat ed with radiation therapy fare best medicine hat 50 mg thorazine buy amex, with improvement of the paraneoplastic symp toms and in some instances apparent cure 1003. Several clinical factors are associated with shorter survival, includ ing extravascular fluid overload, finger nail clubbing, respiratory symptoms, and pulmonary hypertension 1003,2300. Skin changes occur in more than two thirds of cases, most commonly hyperpigmentation and hypertrichosis 1003,1006,2300. Other relatively com mon clinical findings include papilloede ma, thrombocytosis, oedema and serous cavity effusions, weight loss, fatigue, fin gernail clubbing, bone pain, and arthral gias. Microscopy the characteristic lesion in bone mar row is a single or multiple osteosclerotic plasmacytoma. The lesion is composed of focally thickened trabecular bone with associated paratrabecular fibrosis containing entrapped plasma cells. The plasma cells may appear elongated due to distortion by small bands of connec tive tissue. In the bone marrow away from the osteosclerotic lesion, plasma cells are usually < 5%, but can be > 50% in patients with disseminated disease 867, 3738. The plasma cells are distributed interstitially or in small or large clusters, de pending on their abundance. Lymphoid aggregates rimmed by monotypic or polytypic plasma cells are found in half of patients. Megakaryocyte hyperplasia in clusters and often with atypical morpho logical features similar to those seen in myeloproliferative neoplasms is frequent ly observed 867. Lymph node biopsies commonly reveal features of the plasma cell variant of Castleman disease 1006. The acronym stands for telangiectasias, elevated erythropoietin and erythrocytosis, monoclonal gammopa thy, perinephric fluid collection, and intrapulmonary shunting. The reported patient age range is 35-58 years, and it occurs in both men and women. The suc cessful results of treatment aimed at ablation of the monoclonal plasma cells suggest that the monoclonal plasma cells and their M protein product play a major role in the pathophysiology of the disease and its paraneoplastic manifes tations 2153,3585. Erythrocytosis seems to be a uniform feature, associated with a steadily progressive in crease in erythropoietin to very high levels exceeding those produced by most other causes of erythrocytosis. Telangiectasia is reported in most cases, prominent on the face, trunk, arms, and hands. These findings appear to precede development of intrapulmonary shunting and hypoxia. The perinephric fluid, which collects between the kidney and its capsule, is clear, serous, and of low protein content. Spontaneous intracranial haemorrhage and venous thrombosis have been re ported in some patients 3858. IgG kappa predominates; both IgG and IgA lambda have been reported in single cases 2153,2684,3402,3858. Mild erythroid and megakaryocytic atypia has been described in one patient, and reactive lymphoid ag gregates were present in another 3402. Most patients have a percentage of bone marrow clonal plasma cells in the range of monoclonal gammopathy of undeter mined significance (< 10%). Two patients have been reported to have had > 10% plasma cells (one diagnosed with smoul dering plasma cell myeloma), but no case reported to date has fulfilled the criteria for the diagnosis of symptomatic plasma cell myeloma. Slight plasma cell atypia is generally present, with promi nent cytoplasmic vacuolization reported in one case 2153,3402. Immunophenotype the monoclonal plasma cell proliferation is most commonly IgG kappa, but both IgG and IgA lambda have also been re ported. There are no detailed descrip tions of the immunophenotype of the monoclonal plasma cells. Recognition of the disease and initiation of treatment before advanced symptoms develop seems key to successful management. Complete or partial resolution of symp toms has been achieved through treat ment with the proteasome inhibitor bortezomib 2153,3585. A significant decrease in erythropoietin level follow ing treatment is one indicator of good therapeutic response 3402. In at least one case, a bortezomib regimen was followed by autologous stem cell trans plantation, with complete remission and resolution of symptoms 3402. The neoplastic cells reside in the marginal zones of reactive B-cell fol licles and extend into the interfollicular region as well as into the follicles (follicu lar colonization). In epithelial tissues, the neoplastic cells typically infiltrate the epi thelium, forming lymphoepithelial lesions 1044,1782. Most cases occur in adults, with a median patient age in the sev enth decade of life. Men and women are about equally affected, although there are site-specific sex differences, with a female predominance reported for cas es in the thyroid and salivary glands 1, 1999. The chronic inflammation may be the result of infection, autoimmunity, or unknown other stimuli. There is great variation in the strength of these associations, which might relate in part to geographi cal diversity 658,2296,3454. A similar role has been proposed for Campylobac ter infection in patients with alpha heavy chain disease. In patients with Hashimoto thyroiditis, the risk of developing lymphoma is 3 times that in the general population, and the risk of thyroid lymphoma 70 times that in the general population, for an overall lymphoma risk of 0. Approximately 90% of thyroid lym phomas have evidence of lymphocytic thyroiditis 957,4265. Other common sites include the eyes and ocular adnexa (affected in 13% of cases), skin (9%), lungs (9%), salivary glands (8%), breasts (3%), and thyroid (2%) 1999. Staging in patients with multiple extranodal lesions may be challenging, because at least some cases constitute multiple clonally unrelated proliferations rather than truly disseminated disease 2081. Generalized nodal involvement is rare (reported in < 10% of cases) 1905,2140,3952. Microscopy the characteristic marginal zone B cells have small to medium-sized, slightly ir regular nuclei with moderately dispersed chromatin and inconspicuous nucleoli, resembling those of centrocytes, and relatively abundant, pale cytoplasm. Alterna tively, the marginal zone cells may more closely resemble small lymphocytes. Large cells resem bling centroblasts or immunoblasts are usually present, but are in the minority. The lymphoma cells sometimes specifically colonize reactive germinal centres; in extreme ex amples, this can lead to a close resem blance to follicular lymphoma. Lymphoepithelial lesions, defined as aggregates of 3 marginal zone cells with distortion or destruction of the epithelium, may be seen in glandular tissues, often together with eosinophilic degeneration (oxyphilic change) of epithelial cells. Discrete aggregates of monocytoid-like B cells may be present in a parafollicular and perisinusoidal distribution. Cytological heterogeneity is still present, and both plasmacytic differentiation and follicular colonization may be seen. The demonstration of light chain restriction is helpful in the differential diagnosis with reactive hyper plasia. A notable exception is cutaneous marginal zone lymphoma, of which two subsets have been described: a more common class-switched subset (accounting for 7585% of cases) with IgG (including many lgG4+ cases) or IgA expression and usually a T-cell-predominant background, and a less com mon (1525% of cases) lgM+ subset that tends to be B-cell-predominant 455, 1080,4137. The frequencies at which the translocations or trisomies occur vary markedly with the primary site of disease. The t(11;18)(q21;q21) translocation is mainly detected in pulmonary and gas tric tumours; t(14;18)(q32;q21) in ocular adnexa, orbit, and salivary gland lesions; and t(3;14)(p14. Similarly, geographical variability in incidence and anatomical site specificity of the translo cations has been noted, suggesting dif ferent environmental influences, such as infectious and other etiological factors 3340,3813. Cutaneous marginal zone lymphomas have a particularly indolent course, with 5-year survival rates approaching 100% 4320. Involvement of multiple extranodal sites and even bone marrow involvement do not appear to confer a worse prognosis 3953,3954. Clinical features Most patients present with asympto matic, localized, or generalized periph eral lymphadenopathy 137,347. Microscopy Lymph nodes demonstrate a small-cell lymphoid proliferation that surrounds re active follicles and expands into the interfollicular areas. In cases with a diffuse pattern, follicle remnants may be de tected with immunohistochemical stains for follicular dendritic cells and germinal centre markers. The neoplastic cells are composed of variable numbers of mar ginal zone (centrocyte-like and monocy toid) B cells, plasma cells in some cases, and scattered transformed B cells 533, 2834,2884,4046. Most cases occur in adults, with a median age of ~ 60 years, and the proportion of males and females affected is similar 106,4123. A significantly increased incidence has been observed among fe males with autoimmune disorders 442. A relationship to hepatitis C virus infec tion has been detected in some studies 137,4503, but not in others 442,4046. Plasma cell differentiation may be prominent, and the differential diagnosis with lymphoplasmacytic lym phoma or even nodal plasmacytoma may be difficult. However, these cells are usually mixed with small cells and may be more common in the colonized germinal centres 2834,4046. Bone marrow involvement is usually inter stitial or nodular, with an intertrabecular or paratrabecular distribution. Prognosis and predictive factors the 5-year overall survival rate is about 6070% 137. Advanced patient age, B symptoms, and advanced disease stage are associated with a worse prog nosis 106. The proportion of scat tered or clustered large cells does not appear to be of prognostic significance 4046. A At low magnification, note the follicular growth pattern, with pale cells that focally surround portions of reactive germinal centres. B the tumour is composed of a prolifera tion of small cells growing between a reactive germinal centre and an attenuated mantle zone. C IgD stain shows the weak positivity of the tumour cells that surround the negative germinal centre, whereas the residual mantle cells are strongly positive. It presents predominantly in males (with a male-to-female ratio of 20:1) with asymp tomatic and localized disease (stage I in 90% of cases), mainly in the head and neck lymph nodes. The coexpression of more than one of these germinal centre markers in interfollicular areas is very unusual and favours the diagnosis of fol licular lymphoma 1071. Light chain restriction can often be demonstrated by immunohistochemistry or flow cytometry 3366. Trisomy 18 may be present in approximately one fifth of cases, and oc casionally trisomy 3 3366. Par ticularly for these reasons, genetic stud ies in paediatric marginal zone lympho mas are strongly recommended 3866. Lymphomas composed of centrocytes and centroblasts with an en tirely diffuse pattern in the sampled tissue may be included in this category, but are relatively rare at presentation. Progression in cytological grade is common during the natural history of the disease. Primary cutaneous follicle centre lym phomas are separately classified 2242, 3848. Any nodal group can be involved, but most patients pre sent with peripheral lymphadenopathy. The most commonly affected extranodal sites include the gastrointes tinal tract (often in association with mes enteric lymph node involvement), soft tissue, breast, and ocular adnexa. Clinical features Most patients have widespread disease at diagnosis, including peripheral and cen tral (abdominal and thoracic) lymphad enopathy and splenomegaly. Staging the stage of the disease is now deter mined using the Lugano classification, a modification of the Ann Arbor staging system 691. Assessment of bone mar row involvement should be accomplished with bone marrow biopsy. Bone marrow aspiration has a lower yield, due to the difficulty is aspirating cells from the paratrabecular lymphoid aggregates. The designation of a case as A or B (asymp tomatic or symptomatic) is no longer re quired for non-Hodgkin lymphoma subtypes, according to the Lugano system. In eastern Europe, Asia, and developing countries, the incidence is much lower 95. It affects predominantly adults, with a median age in the sixth decade of life and a male-to-female ratio of 1:1. Agricultural exposure to pesticides and herbicides has been associated with an increased risk 33,1257,3678. Neoplastic follicles are often poorly defined and usually have attenuated or absent mantle zones. In some cases, follicles may be irregular and serpiginous, but this growth pattern does not constitute progression to a dif fuse growth pattern. Interfollicular in filtration by neoplastic cells is common and does not constitute a diffuse pat tern. The interfollicular neoplastic cells are often centrocytes that are smaller than those in the germinal centres, with a less irregular nuclear contour, and they may show immunophenotypic dif ferences from the cells in the germinal centres 1015. Infrequent cases have a so-called floral growth pattern that re sembles progressively transformed ger minal centres 4004.

Cells coloured in yellow have not encountered antigen, as opposed to antigen-dependent stages shown in violet. Centrocytes usually predominate over centroblasts, and these neoplasms tend to be indolent. Plasma cells produced in the germinal centre en ter the peripheral blood and home to the bone marrow. T cells recognizing self peptides are eliminated via apoptosis, in a process mediated by cortical epithe lial cells and thymic nurse cells. These various stages of T-cell maturation are reflected in T-lymphoblastic leukaemia/lymphoma. Medullary thymocytes have a phenotype similar to that of mature T cells of the pe ripheral lymphoid organs. There are two classes of T cells: alpha beta T cells and gamma delta T cells 3850. The alpha beta and gamma delta chains are each composed of a variable portion and a constant portion. T cells mature in the thymus gland and then leave to occupy peripheral lymphoid tissues. The double red lines on the cell mem brane represent the expressed T-cell receptor complex. Mature T cells include alpha beta and gamma delta T cells, both of which mature in the thymus gland. They function most prominently in innate immune responses, but they also play a role in the adaptive immune system 2284. The lymphomas of the innate immune system are predominantly extranodal in presentation, mirroring the distribu tion of the functional components of this system. Gamma delta T cells account for < 5% of all nor mal T cells and have a restricted distribu tion, being found mainly in the splenic red pulp, intestinal epithelium, and other epi thelial sites. These sites are more com monly affected by gamma delta T-cell lymphomas, which are otherwise rela tively rare 150,1299,3850. Gamma delta T cells have a restricted range of antigen recognition, and serve as a first line of defence against bacterial peptides, such as heat shock proteins 3850. They are often involved in responses to mycobac terial infections and in mucosal immunity. The T cells of the adaptive immune sys tem, which are heterogeneous and func tionally complex, include naive, effector (regulatory and cytotoxic), and memory T cells. T-cell lymphomas of the adap tive immune system present primarily in adults and are mainly nodal in origin, in contrast with the extranodal T-cell lym phomas of the innate immune system 1816. Th1 cells provide help mainly to other T cells and to macrophages, whereas Th2 cells provide help mainly to B cells, in the production of antibodies 1758A. For example, T regulatory (Treg) cells have diverse functions, including suppressing immune responses to cancer and limit ing inflammatory responses in tissues 2403,4350. Recent studies have tried to relate the pathological or clinical manifestations of T-cell lymphomas to cytokine or chemokine expression by the neoplas tic cells or by accompanying accessory cells within the lymph node. Genetics Several mature B-cell neoplasms have characteristic genetic abnormalities that are important in determining their biologi cal features and can be useful in differen tial diagnosis. The number of mature T-cell lymphomas with recurrent genetic aberrations has increased significantly in recent years with the introduction of next-generation sequencing and mutation analysis. Other genetic tools have also been ap plied in the study of mature lymphoid neoplasms. These include comparative genomic hybridization and more sensitive techniques of array-based copy-number profiling, both of which can identify areas of deletion or amplification within the genome. Most recently, studies have begun to explore changes at the epigenetic level that control the expres sion of multiple genes 2352, 3528. Principles of classification the classification of lymphoid neoplasms is based on all available information to define disease entities 1557. Great caution is ad vised when core needle biopsies are used for the primary diagnosis of lymphoma; fine-needle aspiration is generally inad equate for this purpose. Morphology and immunophenotype are sufficient for the diagnosis of most lymphoid neoplasms. However, no one antigenic marker is spe cific for any neoplasm, and a combination of morphological features and a panel of antigenic markers are necessary for cor rect diagnosis. Most B-cell lymphomas have characteristic immunophenotypic profiles that are very helpful in diagnosis. However, immune profiling is somewhat less helpful in the subclassification of Tcell lymphomas. Although certain antigens are commonly associated with specific disease enti ties, these associations are not entirely disease-specific. Within a given disease entity, variation in immunophenotypic features can be seen. For example, most hepatosplenic T-cell lymphomas are of the gamma delta T-cell phenotype, but some cases are of alpha beta T-cell derivation. An aberrant immunophenotype may suggest or help to confirm a diagnosis of malignancy 1815. Although lineage is a defining feature of most lymphoid malignancies, in recent years there has been an increasing ap preciation of lineage plasticity within the haematopoietic system. Lineage switch or demonstration of multiple lineages is most often encountered in immature haematolymphoid neoplasms, but also can be seen rarely in mature lymphomas 772,1172,1536. There are significant differences in the relative frequencies across geographical regions. The borders are further blurred by conditions such as nodular lymphocyte predominant Hodgkin lym phoma, which manifests many clinical and biological characteristics of Hodgkin and non-Hodgkin lymphomas. Epidemiology Precursor lymphoid neoplasms, includ ing B-lymphoblastic leukaemia/lym phoma and T-lymphoblastic leukaemia/ lymphoma, are primarily diseases of children. Approximately 85% of cases presenting as lympho blastic leukaemia are of precursor B-cell type, whereas lymphoblastic malignan cies of precursor T-cell type more often present as lymphoma, with mediastinal masses. A male predominance is seen in lymphoblastic malignancies of both Bcell and T-cell lineages. According to the World Cancer Report 2014 205, there were 566 000 new cases of lymphoma and about 305 000 deaths due to lymphoma in 2012. Mature B-cell neoplasms constitute > 90% of lymphoid neoplasms worldwide 1,148 and ac count for approximately 4% of all new cancer cases each year. They are more common in developed countries, in par ticular in North America, Australia, New Zealand, and northern and western Eu rope. The incidence of lympho mas, in particular B-cell lymphomas, has increased worldwide, but may be plateauing over the past decade. The Inter national Lymphoma Epidemiology (InterLymph) Consortium is examining factors associated with increased lymphoma incidence using a case-control study methodology 2758. Genetic features are playing an increas ingly important role in the classification of lymphoid malignancies. The diagnosis of lymphoid neoplasms should not take place in a vacuum, but rather within the context of a complete clinical history. Lymphoid malignancies range in their clinical behaviour from indolent to aggres sive. Both morphology and immunophenotype often change over time, as the lymphoid neoplasm undergoes clonal evolution with the acquisition of additional genetic changes. Transformation can arise by di vergent evolution from a common precur sor, or by more-direct linear transforma tion, and examples of both patterns have been shown 1434. In addition, evolution over time does not necessarily lead to the development of a more aggressive lymphoma. The indi vidual B-cell neoplasms vary in their relative frequency in various parts of the world. It was their shared clinical features that first prompted consideration that these lymphomas might be related 3412,3538,4047. One known major risk factor for mature B-cell neoplasia appears to be an abnor mality of the immune system, either im munodeficiency or autoimmune disease. Some autoimmune diseases are also associ ated with an increased risk of lymphoma 4252; for example, patients with Sjgren syndrome or Hashimoto thyroiditis have a particularly high risk of developing B-cell lymphomas 1953,1959. Mutations in genes controlling lymphocyte apoptosis have been linked to increased risk of both autoimmune diseases and lymphomas (mainly B-cell types). In general, T-cell lymphomas are relatively more common in Asia 4217, due to both a higher incidence of some subtypes and a lower relative frequency of some B-cell lymphomas, such as fol licular lymphoma. Differences in viral strain may also affect the incidence of the disease 796, 3869. Other populations at increased risk for this disease are in dividuals of Native American descent in Central and South America and Mexico 275,780,3266,3269, who are geneti cally related to Asians 3280A. The risk appears to be in creased by the combination of two fac tors: immunosuppression and chronic antigenic stimulation. Hepatosplenic Tcell lymphomas are most common, but primary cutaneous and mucosa-associ ated T-cell lymphomas have also been reported 150. Risk factors may include either a high viral load at presen tation or a defective immune response to the infection 3269. The role of the virus in tumour initiation is unclear; however, it does not directly infect neoplastic B cells, and appears to influence lymphoma de velopment through activation of a B-cell immune response. Environmental exposures have also been linked to a risk of developing B-cell lym phoma. Exposure to hair dyes was identified as a risk factor in some older studies, but potential carcino gens have been removed from newer dye formulations 4485. It is highly reproducible and im proves the interpretation of clinical and translational studies. Accurate and pre cise classification of disease entities also facilitates the determination of the mole cular basis of lymphoid neoplasms in the basic science laboratory 1,1815,2759. By convention, the term lymphoma is used when the pro cess is confined to a mass lesion with no or minimal evidence of blood and mar row involvement. If a patient presents with a mass lesion and lymphoblasts in the marrow, the distinction between leukae mia and lymphoma is arbitrary 2792. In many treatment protocols, a value of > 25% marrow blasts is used to define leukaemia. In one literature review, approximately 64% of 98 reported cases were in patients aged < 18 years 2448. A Bone marrow smears showing several lymphoblasts with a high nucleancytoplasmic ratio and variably condensed nuclear chromatin. B Bone marrow aspirate smear with increased haematogones, from an 8-year-old boy, shows lymphoid cells with a high nucleancytoplasmic ratio and homogeneous nuclear chromatin; nucleoli are not observed or are indistinct. B Higher magnification of the same case shows lymphoblasts surrounding a blood vessel. However, these findings are thought to reflect somatic mutations occurring in one twin and shared via in utero circulation rather than constitutional genetic lesions. Marrow and blood involvement may be present, but by definition the pro portion of lymphoblasts in the marrow is < 25% 2345,2448. Coarse azurophilic granules are pres ent in some lymphoblasts in approxi mately 10% of cases. Normal B-cell precursors (haematogones) can mimic lymphoblasts, but they typically have even higher nuclear:cytoplasmic ratios, more-homogeneous chromatin, and no discernible nucleoli. Mitotic figures are usually numer ous, and in some cases there may be a focal so-called starry-sky pattern. The morphological features of B-lymphoblas tic and T-lymphoblastic proliferations are indistinguishable. Granules, if present, may stain light grey with Sudan Black B but are less intense than myeloblasts. They may react with non specific esterase, with a multifocal punc tate or Golgi region pattern that shows variable inhibition with sodium fluoride. The degree of differentiation of precur sor B-lineage lymphoblasts has clinical and genetic correlates. Haematogones show a continuum of ex pression of markers of B-cell maturation, including surface immunoglobulin light chain, and display a reproducible pattern of acquisition and loss of normal antigens 2600. These differences can be very useful in the evaluation of follow-up marrow speci mens for minimal residual disease. Postulated normal counterpart Either a haematopoietic stem cell or a B-cell progenitor Genetic profile but these do not have an impact on prognosis. However, it is likely that some genetic lesions are prognostically impor tant, although there is not yet sufficient evidence to considering these as dis tinct entities. Although they are not strictly part of the definition of genetic entities, they do tend to be associated with particular types. The overall complete remission rate is > 95% in children, versus 60-85% in adults. More-intensive therapy improves cure rates, and there is some evidence that, at least in younger adults, therapy with more-intensive so-called paediatric-type regimens is associated with better outcome 408,1521.

At the time of her intake interview, she reported eating an objectively large amount of food with associated loss of control approximately one to two times per week, followed by purging via self induced vomiting. Molly also reported restriction of eating, in that she attempted to eat fewer than 1,200 calories per day, and to "stay away" from carbohydratebased foods such as breads and desserts. She exercised regularly, but also reported several episodes a week of compensatory exercise-meaning that she exercised specifically to rid herself of calories that she had previously eaten or to compensate for lapses in her restriction of food. For example, she believed that being thin was a reflection of her selfcontrol and willpower, and that if she did not vigilantly maintain her thinness she was "lazy. Standardized assessments of drinking behavior completed during her intake revealed that she consumed more alcohol during the week than 95% of women her age. For example, on nights when she had plans to go out and drink, she often ate only vegetables during the day so that she could "save the calories" for alcohol, and maintain her 1,500calorie limit. Therefore, she often experienced negative consequences for drinking, such as blacking out or vomiting. However, she reported that her symptoms then dramatically improved during a study abroad trip to Spain for a full semester during her second year. She stated that "for some reason" she did not care as much about being thin and what she was eating while in Spain, and she allowed herself the freedom to eat whatever she wanted. She reported that during that time she had very few episodes of binge eating, purging, and compensatory exercise. On her return to the United States, she described suddenly "feeling fat-how did I let myself gain this much weight Despite dieting and exercising, she made conscious efforts to refrain from binge eating and purging, stating that she wanted to maintain the gains that she had made while abroad. However, several months prior to her intake, she was sexually assaulted by an acquaintance. Her friends were dismissive of her concerns about the sexual assault, telling her that she "hooked up with X" while she was drunk and that it was "not a big deal. Bulimia Nervosa 219 her binge eating and purging symptoms resurfaced, and she began increasing her restriction as a result. She stated that she wanted help with binge eating and purging, as well as expressed feelings of depression and anxiety. Objective binge eating consists of eating what other people would consider an unusually large amount of food, coupled with a sense of loss of control over the eating episode. Inappropriate compensatory behaviors include selfinduced vomiting, laxative use, fasting, or excessive exercise (American Psychiatric Association, 2013). Thus, most cases occur during or after puberty, although some rare prepubertal cases have been documented (Stein, Chalhoub, & Hodes, 1998). Importantly, the age of onset for men may be later, with a peak risk period occurring between the early and midtwenties (Harvey & Robinson, 2003). Notably, there is also evidence that disordered eating behaviors typically develop separately. Binge eating and dietary restriction typically have an earlier onset than purging behaviors (Stice, Killen, Hayward, & Taylor, 1998). Data from community samples of adolescents suggest that binge eating begins closer to 16 years of age, while purging behaviors may be delayed until almost 18 years of age (Stice et al. Additionally, some studies report that bulimic behaviors are developing in younger adolescents (Currin, Schmidt, Treasure, & Jick, 2005) and that earlyonset of disordered eating behaviors may be related to more deleterious outcomes (Kotler, Cohen, Davies, Pine, & Walsh, 2001). It is clear that adolescence and young adulthood represent highrisk periods for the development of bulimic behaviors. Individuals with bulimia generally report high functional impairment and are at elevated risk for deliberate selfharm and suicidality (Keel, Brown, HolmDenoma, & Bodell, 2011; Stice et al. According to data from the World Health Organization World Mental Health Survey Initiative, 84. Common cooccurring diagnoses include personality 220 Sarah Fischer, Kendra Davis, and Lauren Breithaupt disorders (especially borderline personality disorder), mood disorders, impulse disorders, posttraumatic stress disorder, all other anxiety disorders, and, as in the case of Molly, substance use disorders. The myriad of medical complications associated with bulimia are primarily attributed to purging behaviors and range in severity. Selfinduced vomiting may cause dental cavities, periodontal disease, enamel destruction, esophagitis, esophageal tears and bleeding, esophageal ulcers, and, more rarely, esophageal rupture (Mehler, 2011; Mehler, Crews, & Weiner, 2004). Individuals who use ipecac syrup to induce vomiting may suffer from muscle weakness and pain, irreversible cardiomyopathy, congestive heart failure, ventricular arrhythmias, and even death (Mehler, 2011; Mehler et al. Inappropriate longterm laxative use may result in neuromuscular damage to the colon such that passing fecal matter is slow and incomplete without the continued use of stimulant laxatives. Extreme cases of constipation, resulting from cathartic colon syndrome, may require a colectomy and the insertion of an ostomy bag (Mehler, 2011; Mehler et al. Electrolyte imbalances due to selfinduced vomiting, laxative use, and/or diuretic use, while somewhat rare, include hypokalemia, hypochloremia, elevated serum bicarbonate, and hyponatremia (Mehler, 2011; Mehler et al. Even though medical treatment and the cessation of purging behaviors can reverse many of these conditions, some are irreversible (Mehler, 2011; Mehler et al. Therefore these complications highlight the severity of bulimia and the importance of early detection and treatment. The first stage of treatment focuses primarily on the normalization of eating patterns and the reduction of binge eating and purging. During this stage, therapists assist clients with eating three scheduled meals and two scheduled snacks per day, problem solve triggers for binge eating, and provide psychoeducation regarding the ineffectiveness of dieting and purging. Daily recorded monitoring of eating behaviors is also initiated during the first few sessions. Finally, clients are asked to stop weighing themselves outside of the session and to start weighins in the session with the clinician. Activities in this stage of treatment are focused on the identification and restructuring of distorted thoughts surrounding shape and weight. Strategies often used in this stage of treatment include creating an exposure hierarchy of feared and avoided foods, behavioral experiments designed to test thoughts about the importance of thinness, as well as traditional cognitive restructuring. Individuals begin restrictive eating regimens, which are extremely difficult to maintain. Negative affect Dietary restriction Binge eating Compensatory behaviors vulnerability to binge eating. Binge eating is then followed by purging, in the hope that it will counteract the effects of the binge. Following binge and purge episodes, individuals often feel worse about themselves, experience exacerbated concerns about shape and weight, and reinitiate restrictive eating patterns. Negative emotions both are a result of binge and purge episodes and may trigger them. First, very few studies have the methodological rigor necessary to actually answer questions about the specificity of selfesteem to eating disorders or how important this concept is in the maintenance of symptoms. The majority of studies that assess selfesteem and eating disorder symptoms are crosssectional or utilize retrospective recall (Jacobi, Hayward, de Zwaan, Kraemer, & Agras, 2004). Thus, it is very difficult to determine if low selfesteem actually precedes the development of an eating disorder, and is in turn significantly linked to its onset. Additionally, several studies which utilize prospective designs and assess concepts similar to selfesteem have folded selfesteem into the broader construct of negative emotionality or trait negative affect (Jacobi et al. One longitudinal study of eating disorder onset found that negative self evaluation as a component of negative emotionality increased risk for the development of disorder eating symptoms (Leon, Fulkerson, Perry, Keel, & Klump, 1999). Another fiveyear 222 Sarah Fischer, Kendra Davis, and Lauren Breithaupt longitudinal study using a large population based sample found that depression and low selfesteem were associated with the onset of binge eating (Goldschmidt, Wall, Loth, le Grange, & NeumarkSztainer, 2012). However, low selfesteem is also associated with several forms of psychopathology, not just eating disorders. For example, low selfesteem figures prominently in vulnerability models of the development of depression. And low selfesteem is significantly associated with both depression and anxiety disorders (Sowislo & Orth, 2013). Thus, it is doubtful that low selfesteem is specific to the development of eating disorders, even though the majority of individuals with eating disorders may present to treatment with low selfesteem. The authors did not find evidence of any reliable change in selfesteem in their data analysis (Lundgren et al. This risk factor is often a significant predictor of later disordered eating in longitudinal multivariate analyses, when many other potential risk factors are added to the models (Jacobi et al. Finally, prevention programs which specifically attempt to alter thin ideal internalization and to target women with elevated weight and shape concerns have the most success in the prevention of eating disorders (Stice, Shaw, & Marti, 2007). Dieting Weight and shape concerns have been defined in several different ways across studies. Weight and shape concerns can include fear of weight gain, negative body image, internalization of the thin ideal, and body dissatisfaction (Jacobi et al. For the purpose of this chapter, the term "weight and shape concerns" includes all of these constructs. Internalization of the thin ideal refers to an individual having an awareness of the "ideal" appearance and figure (slender) that is promoted in Western media and of its social meaning, and incorporating this ideal into schemas for selfevaluation (Thompson & Stice, 2001). Body dissatisfaction arises from thin ideal internalization and the resulting social comparison to peers or celebrities who have this idealized appearance. It is targeted directly in the first stage of treatment with psychoeducation, food monitoring, and the implementation of scheduled meals and snacks. It is targeted in the second stage of treatment via exposure to "highrisk" foods and behavioral experiments designed to break food rules. Dieting has been defined as intentional behavioral efforts at restricting food intake for the purpose of losing weight or altering shape (Lowe & Kral, 2006). Some authors distinguish dieting from restrained eating (Lowe & Kral, 2006; Lowe, Witt, & Grossman, 2013).
