Children aged 2 years in the micafungin treatment arm experienced a smaller mean peak decrease in the estimated glomerular fltration rate than those in the L-amB arm zombie infection nokia 5228 discount cephalexin 500 mg amex. Fever was observed in one patient with a National Cancer Institute toxicity grade of 3 antibiotic resistance vertical horizontal cephalexin 250 mg discount, and facial erythema was observed in another patient, which resolved after the infusion rate was decreased. Invasive candidiasis associated with neutropenia in patients undergoing bone marrow transplantation has been treated successfully with this class of antifungals. These agents should be considered as frst-line treatment of invasive candidiasis in neutropenic or critically-ill children (strong, moderate). Although lipid amphotericin B formulations appear to be at least as effective as conventional amphotericin B for treating serious fungal infections,73,74 the drugs are considerably more expensive than conventional amphotericin B. Two lipid formulations are used: amphotericin B lipid complex and liposomal amphotericin B lipid complex. However, when recurrences are frequent and severe, secondary prophylaxis may be considered on a case-by-case scenario. Discontinuing Secondary Prophylaxis In situations when secondary prophylaxis is instituted, no data exist on which to base a recommendation regarding discontinuation. In less severely ill children who have not had previous azole therapy, fuconazole is recommended (strong, moderate).

Infection usually results from inhalation of spores (arthroconidia) produced by the mycelial form which grows in arid, windy environments with hot summers preceded by rainy seasons. Increased infection rates have been attributed to population shifts to endemic regions, climatic conditions, and better recognition. Clinical Manifestations Coccidioidal infection can range from a mild, self-limited, flu-like illness to more severe, focal or disseminated illness, including pneumonia, bone and joint infection and meningitis. Immunocompromised individuals and previously healthy blacks, Hispanics, and Filipinos with coccidioidomycosis are at increased risk of dissemination, as are pregnant women who acquire coccidioidal infection during the second or third trimester22 or the postpartum period. Children with meningitis may present with headaches, altered sensorium, vomiting, and/or focal neurologic deficits. Diagnosis Because signs and symptoms are non-specific, the diagnosis of coccidioidomycosis should be among those considered in patients who reside in or have visited endemic areas. The observation of distinctive spherules containing endospores in histopathologic tissue37 or other clinical specimens is diagnostic. Pyogranulomatous inflammation with endosporulating spherules is seen in affected tissue specimens with haematoxylin and eosin. Spherules can also be observed using Papanicolaou, Gomori methenamine silver nitrate, and periodic acid-Schiff stains. The laboratory should be alerted to clinical suspicion of coccidioidal infection so that specimens can be handled in secure and contained fashion to minimize hazards to laboratory personnel. Presence of IgM-specific coccidioidal antibody suggests active or recent infection although, in instances in which IgG-specific antibody is absent, data are conflicting about potential false positives. IgG-specific antibody titers often become undetectable in several months if the infection resolves. Serial testing36 following at least a 2 week interval may be needed to demonstrate this. Dissociation of immune complexes has increased the sensitivity of detection of coccidioidal antigen in serum. These include disturbing contaminated soil, archaeological excavation, and being outdoors during dust storms. If such activities are unavoidable, use of high-efficiency respiratory filtration devices should be considered. Physicians who infrequently treat children with coccidioidomycosis should consider consulting with experts. Management should also include education directed at reducing the probability of re-exposure to coccidioidal spores. In a randomized, double-blind trial in adults, fluconazole and itraconazole were equivalent for treating non-meningeal coccidioidomycosis. The length of amphotericin B therapy is governed by both the severity of initial symptoms and the pace of the clinical improvement. An effective dose of fluconazole in adults is 400 mg/day, but some experts begin therapy with 800 to 1000 mg/day. If therapy is succeeding, titers should decrease progressively; a rise in titers suggests recurrence of clinical disease. However, if serologic tests initially were negative, titers during effective therapy may increase briefly and then decrease. Adverse effects of amphotericin B are primarily those associated with nephrotoxicity. Infusion-related fevers, chills, nausea, and vomiting also can occur, although they are less frequent in children than in adults. Hepatic toxicity, thrombophlebitis, anemia, and rarely neurotoxicity (manifested as confusion or delirium, hearing loss, blurred vision, or seizures) also can occur (see discussion on monitoring and adverse events in Candida infection). Skin rash and pruritus may be observed, and cases of Stevens-Johnson syndrome have been reported. Asymptomatic increases in transaminases occur in 1% to 13% of patients receiving azole drugs. In instances in which patients with coccidioidal meningitis fail to respond to treatment with azoles, both systemic amphotericin B and direct instillation of amphotericin B into the intrathecal, ventricular, or intracisternal spaces, with or without concomitant azole treatment, have been used successfully. Thus, development of hydrocephalus in coccidioidal meningitis does not necessarily indicate treatment failure. Relapse after cessation of therapy is common, occurring in as many as 80% of patients. Preventing Recurrence Lifelong suppression (secondary prophylaxis) is recommended for patients following successful treatment of meningitis.

Some reside in the lymphatic tissues that are primarily concentrated in lymph nodes medicine for uti while pregnant buy cephalexin uk, thymus antimicrobial iphone 4 case discount 500mg cephalexin with visa, spleen antibiotic resistance in agriculture effective cephalexin 250mg, and in most of our major organ systems antibiotics yellow tongue cheap 500 mg cephalexin. Leukemia infection pus order cephalexin 250 mg otc, lymphoma infection with red streak cheap cephalexin 250mg amex, and multiple myeloma are all cancers of the blood-forming organs, or hematopoietic neoplasms. Nearly every stage of the hematopoietic process can give rise to a distinct type of cancer. Historically, scientists and physicians have classified these diseases by their locations in the body, the appearance of affected cells under the microscope, and the natural progression of the diseases. In leukemia, the cancerous cells are discovered circulating in the blood and bone marrow, while in lymphoma, the cells tend to aggregate and form masses, or tumors, in lymphatic tissues. Myeloma is a tumor of the bone marrow, and involves a specific subset of white blood cells that produce a distinctive protein. Leukemia can arise in either of two main groups of white blood cell types -lymphocytes or myelocytes. Either type of leukemia can be acute, a rapidly progressing form of the disease in which the affected cells are very immature and unable to serve their proper purpose, or chronic, which progresses more slowly and is distinguished by cells that are relatively well differentiated but still function poorly. Leukemias, lymphomas, and myelomas share some common features, but there are major differences among them and there are similarities and differences within each disease group. These cancers actually represent a large number of diseases that vary significantly in their causes, molecular profiles, and natural progression. In the past decade we have a experienced a revolution in the field of molecular biology that has brought new tools that are helping us refine cancer classification in terms of the molecular changes that distinguish a normal cell from a cancerous one, and draw differences between cancerous cells of different types. These profiles will be used to define more informative, and clinically predictive, molecular classification schemes for human cancers. This genetic characterization can help explain why patients diagnosed with the same cancer differ dramatically in their responses to treatment. For 40 percent of patients with this diagnosis, standard multi-agent chemotherapy is curative. A compelling clinical problem is to understand why the remaining 60 percent of patients succumb to this disease despite chemotherapy. This new technology is capable of measuring the activity of tens of thousands of genes at the same time, thus creating a molecular portrait of the cells being studied. Lymphochip microarray analysis of gene expression in diffuse large B-cell lymphoma samples revealed that this single diagnosis actually combines two distinct diseases that differ in the expression of hundreds of genes. The two types of diffuse large B-cell lymphoma that were discovered each resemble a different type of normal B lymphocyte, suggesting that these cancers have distinct cellular origins. Clinically, patients with these two types of diffuse large B-cell lymphoma had strikingly different responses to chemotherapy. Patients with one lymphoma subtype, termed germinal center B-like diffuse large B-cell lymphoma, had a favorable prognosis: 75 percent of these patients were cured by chemotherapy. Patients with the other lymphoma subtype, termed activated B-like diffuse large B-cell lymphoma, had a poor response to chemotherapy with less than one quarter of these patients achieving a long-term remission. This study provides a clear demonstration that genomic-scale gene expression analysis can define clinically important subtypes of human cancer. This powerful new technology is now being used to study many different types of cancers, including leukemia and multiple myeloma, in an attempt to identify disease subgroups. For example, a new project, "Molecular Taxonomy of Pediatric and Adult Acute Leukemia," will attempt to correlate the expression pattern of over 30,000 genes with treatment outcome and with cytogenetic abnormalities for both acute lymphocytic leukemia and acute myeloid leukemia. In the future, such gene expression profiling of cancer cells will be used to guide patients towards therapies that are tailored for their particular diseases. Leukemiathe leukemias are very heterogeneous, with patterns of occurrence differing by age, sex, and racial and ethnic group. The causes of leukemia in children and adults are largely unknown, but increased or decreased risks for developing leukemia have been associated with several factors. Occupational exposures to ionizing radiation and certain chemicals such as benzene have also been linked with increased risk of acute leukemia. In addition, cigarette smoking has been associated with modest increases in acute leukemia but the evidence is not yet conclusive. Over the last ten years, researchers have studied the histologic types of lymphoma that are on the rise; illnesses, including other cancers, associated with lymphoma; occupational groups that may be at increased risks; and the role of genetic susceptibility. Recent research has identified several possible candidates for increasing risk including pesticides, organochlorine compounds, solvents, drinking water nitrates, and hair dyes. There has been considerable research on the association between infectious agents and cancer. The international consortium of collaborators will examine pathology, infectious agents, family history data, genetic factors, and methodologies needed to accurately assess possible links with the development of lymphoma. Multiple Myelomathe median age for diagnosis of multiple myeloma is 71 years of age. The incidence of multiple myeloma is much higher in blacks than whites, and is higher among males. Similar to incidence rates, the death rates are higher among males than females and higher among blacks than whites. This is one of the few cancer sites in which the survival rate is higher for blacks than for whites. The causes of multiple myeloma and the reasons for the racial disparity in incidence are unclear. Some studies have suggested the role of ionizing radiation, certain organic solvents and chemicals, as well as employment in farming and agricultural occupations. Recent attention has also focused on viruses and other infectious agents, but their role in the etiology of myeloma remains unclear. There is growing evidence that certain cytokines and chromosomal abnormalities may be involved in the pathogenesis of multiple myeloma. These laboratory-based genetic measures need to be incorporated into future epidemiologic studies to better understand the complex relationships between genetic and environmental factors in the development of this disease. The rarity of this cancer makes it difficult to adequately investigate in a single study, so that collaborative efforts involving a variety of hematopoietic malignancies are being pursued. In the last decade, there has been an enormous investment in defining molecularly targeted agents in cancer chemotherapy. Recently we have seen some inspiring success stories, all of them direct results of this new approach. Additional trials are assessing the potential benefits of combining Gleevec with other chemotherapeutic agents. Molecular analyses of other types of leukemia have now produced the identification of more than 100 additional oncogene targets that may be accessible to similar drug development strategies. Currently, for both children and adults, rituximab is under study in combination with other therapies, including other monoclonal antibodies, attempting to attack multiple targets on a single cell type. Generally, leukemias, lymphomas, and multiple myelomas are derived from cells of the immune system and therefore frequently express antigens that are present on normal immune cells such as B-cells or T-cells. Since these proteins are not present on other human cells and are not present on the stem cells that give rise to normal B-cells and the T-cells, the antigens are excellent targets for cancer therapy. Remarkable anti-tumor activity has been observed in patients with hairy cell leukemia. Other antibodies under investigation are coupled to other potent anti-tumor substances, like radioactive molecules or anti-tumor antibiotics, and have the potential advantage of being able to deliver this tumor killing substance directly to the tumor site, where they attack antigen-positive tumor cells that other therapeutic agents might not penetrate well. Immunotherapeutic approaches for treatment of multiple myeloma are also being evaluated. Investigators are examining the potential for immunization strategies in which a normal donor is vaccinated with the myeloma protein. The normal donor forms antibodies, called idiotype antibodies, and these are used to treat the patient. Preclinical studies of idiotype immunization demonstrate that this approach can induce an immune response that prevents tumor relapse or progression in myeloma models. Basic research findings have identified a plethora of potential therapeutic targets for further exploitation. There is an ever lengthening list of promising agents that affect cell cycle regulation, gene expression, apoptosis (programmed cell death), and other cell functions, currently undergoing or awaiting investigation in clinical trials. Finding effective treatments for multiple myeloma has proven extremely challenging for cancer researchers. Thalidomide effectively arrests tumor growth by stimulating anti tumor immune response, interfering with communication between tumor cells and the surrounding tissue, and inhibiting the growth of new blood vessels (angiogenesis) near the tumor. Astute researchers theorized that the same feature could prove useful in restricting the blood supply to tumors. New trials are seeking to optimize the role of this agent, and some other antiangiogenic agents are being evaluated, as well. Because anti-angiogenic drugs have the potential to cause defects in a developing fetus, pregnant woman are excluded from participating in clinical research on these drugs. Sometimes cancers become resistant to treatment with radiation therapy or chemotherapy. Because the high doses of chemotherapy can destroy the bone marrow, marrow is taken from the bones before treatment. The marrow is then frozen, and the patient is given high-dose chemotherapy with or without radiation therapy to treat the cancer. The marrow is then thawed and given back to the patient to replace the marrow that was destroyed. If the marrow is taken from another person, the transplant is called an allogeneic transplant. Another type of autologous transplant is called a peripheral blood stem cell transplant. Autologous stem cell transplantation clearly benefits patients in a chemotherapy sensitive relapse of their disease, but its role as initial treatment is undefined. A national trial is comparing the efficacy of initial transplantation with transplantation at the time of first relapse. Other studies are evaluating the role of biological therapies such as interleukin-2, and immune response stimulator, and rituximab for their effectiveness in enhancing the benefit of transplantation. Many patients do not benefit from stem cell transplantation, and major efforts are directed at identifying the reasons and to develop methods to improve on these results. Moreover, age restrictions limit the number of patients who might be eligible for this procedure. Recently, investigators have described their experience with patients over the age of 55 years. As a consequence, the notion that more intensive treatment is better is being challenged, and the role of the immune system in cancer progression is being better delineated. Data are provided from more than 400 centers and there are now data for more than 65,000 transplants worldwide. The information collected is used for determining transplant regimens for specific clinical situations, identifying prognostic factors, comparing transplant regimens, comparing transplant with non-transplant approaches, evaluating cost and cost-effectiveness, planning clinical trials, and developing approaches to evaluate outcomes. Our clinical trials program is the place where promising new strategies discovered at the laboratory bench are applied to real human problems at the bedside. Clinical trials offer cancer patients access to state-of-the-art care, and provide us the opportunity to learn something from every patient that may help someone else. Our rapid pace of discovery in the basic biology of cancer is refining our knowledge of how to intervene in cancer development, and clinical trials are the crucial final step in bringing these discoveries to people who are battling cancer. Conclusion Progress in our understanding of cancer and our ability to detect and treat it have led to a real and continuing decline in the cancer incidence and death rates. However, our excitement over important scientific progress and the very real human gains that result is tempered by the knowledge that far too many Americans continue to suffer and die from cancer each day. Moreover, all groups of people are not benefiting equally from our advances against cancer. Plans call for increasing fundamental research into the social causes of health disparities, the psychosocial factors that mediate them, and the biologic pathways that can explain their impact. In addition, we will expand our cancer control intervention and population research on disparities, better define and monitor cancer-related health disparities, and strengthen training and education in this research area. Effective communication empowers people to make informed cancer-related decisions and to engage in behaviors that will improve their health. Few other initiatives have the potential to simultaneously improve health outcomes, decrease health care costs, and enhance community satisfaction. Our intent is to learn how to help people distinguish important from insignificant health risks and deal with contradictory or inaccurate health messages so they can make informed choices. Too many Americans, for a host of reasons, lack access to high quality, cutting-edge cancer treatment and care. Our goal is to enhance the state of the science for defining, monitoring, and improving the quality of cancer care and inform Federal decision making on cancer care delivery, coverage, and regulation. We have learned the value of including as broad a constituency as possible in our review, advisory, and planning activities, and we have forged new relationships with patients, practitioners, scientists in different fields of research and medicine, other government agencies, private sector companies, innovators in technology, and many other partners where such alliances were rare or non-existent only a few years ago. Our goal is to eradicate cancer and save the lives of those who would otherwise be lost to us. Chairman, for giving me this opportunity to share with you our progress against hematologic cancers. Furthermore, the tumor growth affected by miR 222-3p was further investigated based on animal experiment. A previous study indicates that the intestinal 12 inflammation can be aggravated by up-regulation of miR-222 during the disease progression. Finally, the tumor growth affected by miR-222 was investigated based on animal experiment. No previous chemotherapy, radiation or other biological treatments were considered as the inclusion criteria. Moreover, a total of 26 patients with pathological diagnosis of reactive lymphoid hyperplasia were selected as controls.

Animals exposed to stress early in life have a decrease in branching of the neurons in this part of the brain. If there is something that looks like it might be scary, but isnt really, this brain area shuts off the fear reaction from the amygdala. We think this brain problem is the reason they have fear reactions all the time, even if there isnt something that is a real danger to them. The Stress Response Gone Haywire With repeated stress and traumas over time, the parts of our body responsible for our survival start to go haywire. The cortisol and adrenaline hormones that help us run away or fight back get out of whack, the hippocampus that helps us remember past threats gets damaged, the amygdala that activates the fear response over-reacts, and the frontal cortex that turns off the fear response doesnt work the way it used to . How to Start to Move On From Psychological Traumathe first step on the pathway to recovery from psychological trauma is to identify the invisible barriers blocking you. You then must educate yourself about what trauma is and the corrosive and subtle ways it can affect you. These barriers can take many forms, and arent always easy to identify right away. As we discussed in the last chapter, if not dealt with correctly, trauma leads to changes in the brain that make the painful memories keep coming back when they are least expected. To get rid of these painful memories and the emotions that flood the body, people initiate evasive maneuvers. They drink or take drugs to dampen down the feelings, to eliminate the stress hormone responses and to blot out the painful memories. But these behaviors can become barriers in your path toward recovery from psychological trauma. Research has shown that alcohol and drugs, like heroin, or related pain killers, like oxycodone, sedating benzodiazepine drugs (Xanax, Valium), and marijuana, actually reduce the stress hormones and make stress systems betterin the short term. Some people may work all the time, or lose themselves in endless affairs, or find other activities to distract their minds from their traumas. These people go to extraordinary ends to avoid their memories, but they are fighting against the tide, because trauma has changed their neurological systems. All of these ways to try and get away from the trauma are ultimately barriers to your recovery. My brother dropped out of his first year of college when he was eighteen and I was twelve. During that time, he drifted around the country, working odd jobs, often without a permanent address, and finally enlisted in the Air Force, where he later obtained a higher education and went through officers training school. As I explained in Chapter One, after the death of my mother, I felt sadness, guilt, and insecurity. In a variety of ways, I was told to get over it, and I felt if I were a stronger, better person I could do just that. Because I couldnt move beyond it, because I was haunted by the memory of the loss, I felt inadequate and thus insecure. Later in life, I poured my energies into achieving good marks in school, got into medical school, and developed a successful career. I thought I had finally moved on, gotten over the past, but the demons from my past were always there, and sooner or later I would have to deal with them. I describe how my demons finally caught up with me forty years after my personal trauma, and what happened next, in my bookthe Goose That Laid the Golden Egg, published in 2011. The Desperate Need to Escape from Traumathe desire to suppress the memories of the traumatic event can result in long-term harm to the psyche and/or in self-destructive behaviors we use to distance ourselves from the initial trauma. These responses, a natural by-product for some reason of psychological trauma, are compounded by the feeling of futility and inadequacy that comes with the realization that you cant just snap out of it. Most people blindly forge on with self-destructive behaviors, with no clue about the root cause. Self-Medication of Trauma Often people go down the road of alcohol or substance abuse, not knowing that their psychological trauma was directly responsible for their problems. No one will ever bring up the possibility that you have relapses when you are exposed to reminders of your trauma. We all know that smoking cigarettes causes lung cancer, but did we know that childhood abuse causes drug addiction Well, it turns out that some drugs, heroin being the most effective, shut off the activity of the adrenaline center in the brain located in the brain stem, called the locus coeruleus. The problem is that sooner or later the consequences of drug usage catch up with them. Do you go to an addiction center that ignores trauma, and tries to feed you their canned program You can do this if you want to and you have a lot of money, but I dont think it will help you. You are probably reading this book because you think there might be something more, or because you have run out of options. Trauma victims dont make the connection between the trauma in their lives and their behavior in many ways. With the tools we provide in this book, you can start to overcome those barriers, and make progress on your path toward a real recovery from psychological trauma. The first step is to educate yourself about what effects psychological trauma has had upon you and your behavior. She left that job to work for an insurance company, but she continued to have problems, feeling overwhelmed and physically exhausted throughout the day. She would sleep the entire weekend to recuperate enough to go back to work, and was unable to be intimate with her husband. I met with her once a week in my home office in New Haven, Connecticut, when I was an Assistant Professor of Psychiatry at the Yale University School of Medicine. Since then, however, due to the efforts of renovation-minded urban pioneers such as ourselves, the neighborhood was making a comeback. However, one night, as the daylight filtered through the window and the darkness of late autumn entered my office, she recalled a previously suppressed memory of something bad that happened in childhood. She didnt have the opportunity to deal with her trauma earlier because she didnt have the right forum to discuss her feelings. She felt a conflict about revealing the abuse perpetrated by her grandfather to her parents. It is also possible that her own parents were not willing to hear terrible news about their daughters abuse by their own parent. The chronic stress of the trauma and keeping the secret led to long-term changes in her stress hormone systems. Repeated increases in cortisol caused by events that would remind her of the trauma led to thinning of the lining of the stomach resulting in her gastric ulcers. Only when she faced another traumatic stressor (the assault) did her defenses become so weak that she could no longer suppress the memories of the sexual abuse she experienced as a child. With time, we were able to go back and re-write her history, to incorporate what happened to her, so that she no longer needed to invest so much energy in walling off parts of her memories. As the above story illustrates, victims are often able to contain their traumatic memories until a further stressor weakens their defense systems. The Stress of Duke Medical School I was a twenty-five-year-old student at Duke University School of Medicine, in Durham, North Carolina, and I was coming unglued. Under the enormous stress and competition of med school, all my insecurities and never resolved hurt could no longer be contained. Like many trauma victims, rather than deal directly with the pain of my mothers death, I tried just not to think about it, to get over it. For years, I pushed the bad feelings and memories away, until stress dissolved my defenses. Now that I was under the maximum stress of Duke Med, I couldnt do that any longer. By the third year, I was so burned out that I felt I had to go home, back to my native Washington state, to recharge my batteries. It was like the title of the book by the novelist, Thomas Wolfe, You Cant Go Home Again. Where we come from, our core moral values, our family history, give us our identity, our sense of security and peace. As a result of my traumatic past, the core of myself, the collection of memories of my childhood, were painful and distorted. I couldnt move forward because I could no longer stand the pressure, but I was afraid to go back because of the pain associated with the past. Something in me knew, however, that if I didnt go back and look at the past, there was no way I could move forward. Facing the Past So for the first time, instead of running away from my memories, I faced them. I faced them literally when I came upon a box in the basement of my childhood home. I opened it and saw a picture of my parents, very young, dressed in white, together holding a knife used to cut a wedding cake. Another photo showed my parents sitting on the hood of a 56 Chevy with tall Washington State Douglas Firs behind them, drinking together out of a milk carton. I found yet another picture of my mother in a plain dress holding a baby (my sister) with the solid gold wheat fields of the Dakota prairie as a background. The image I had of my mother was that of a difficult woman who was messy and who didnt clean up after herself or her children, but here I saw a beautiful woman in her prime who looked as if she loved her children and who took great care of herself and them. It dawned on me then that perhaps I had the wrong image of my mother all this time, and that if the memory of my mother was distorted, perhaps other memories were equally inaccurate. I began the process by getting information from photographs, relatives, and friends. This information helped me to modify the beliefs I had wrongly held about the events and about myself. The information also helped me to come to terms, for the first time, with the painful memories and feelings I had been pushing away for years. I later re-wrote the history of my own history (including the background story) in my bookthe Goose That Laid the Golden Egg, originally published in 2011 and released in a 2nd edition in 2014. Betsy Re-Writes the Past Traumatic memories are often not only distorted, but also supercharged with emotion. Betsy was raped as a teenager, and after that, every time she had physical contact with a man, she felt intense fear and anxiety. But since she wanted to have the intimate relationship that comes with sexual relations, she would force herself to go through with intercourse. This woman was suffering from an inability to turn off the fear response, even when there was no true threat. As we indicated in Chapter 2, the fear memory is stored in a part of the brain called the amygdala. Another part of the brain, called the frontal cortex, is responsible for extinction of fear. In time, when it becomes clear there is no true threat associated with the experience, the frontal cortex will inhibit the fear responses coming from the amygdala. But in some trauma victims, the frontal cortex doesnt turn on properly, and the fear response keeps coming from the amygdala, again and again. For Betsy to move beyond her predicament, she had to re-write her memories related to intimacy with men. Her treatment involved a detailed exploration through psychotherapy of all of the thoughts, feelings, and ideas in her mind at the time of the original rape. We explored her intense fear, the physical sensations that accompanied the rape, some of the thoughts that were going through her mind. It was necessary for her to learn as much as possible about what had actually happened, to re-visit issues about whether there was anything she could have done to avoid the rape. Re-writing the memory also involved re-exposing herself to being touched by a man, and in essence replacing the fear-memory associated with the rape with the positive memory associated with being with a man who was bringing pleasure instead of victimization. Trauma Spectrum Disorders Trauma can have a number of effects on the individual; in more extreme versions the effects can rise to the level of a mental disorder. These disorders were described as trauma-spectrum disorders in the book Does Stress Damage the Brain This demonstrates that trauma-related mental disorders are not discrete disorders, but rather a spectrum of symptoms with some traumatized persons exhibiting more of one core of symptoms than another. Major Depression Psychological trauma can lead to a mental disorder called major depression. Depression is very common, affecting 15% of people at some time in their lives (Kessler, R. Less than a third of these people, however, are being treated for their depression. Symptoms of Major Depression If you feel depressed most of the day every day or have trouble concentrating or focusing, you may suffer from depression. This may be associated with thoughts that you would be better off dead, or active plans to kill yourself, a loss of energy, appetite, and interest in things. You may have a loss of interest in sex, or in doing things that you used to like to do.
