The electrical discharge of neurons associated with seizure activity stimulates a marked rise in cerebral metabolic activity. Estimates from animal experiments indicate that energy utilization during seizures increases by more than 200", while tissue adenosine triphosphate (ATP) levels remain at more than 95" of control, even during prolonged status epilepticus. The brain generally withstands the metabolic challenge of seizures quite well because enhanced cerebral blood flow delivers additional oxygen and glucose. Mild to moderate degrees of hypoxemia that commonly accompany seizures are usually harmless. However, severe seizures and status epilepticus can sometimes produce an imbalance between metabolic demands and cerebral perfusion, especially if severe hypotension or hypoglycemia is present. A marked increase in glutamate release, which occurs during a prolonged seizure, is likely to result in the activation of all types of glutamate receptors. Although kainic acid produces seizures in the immature brain, it produces little cytotoxicity.

This chapter demonstrates how social work ethics apply to ethical and legal decision making in forensic social work practice. It discusses the context of social work practice in legal systems. The chapter also details the basic structures of the United States (U.S.) civil and criminal legal systems. It lays the foundation for the criminal and civil court processes in the United States and introduces basic terminology and a description of associated activities and progression through these systems. The chapter focuses on providing an introductory, and overarching, picture of both civil and criminal law in the U.S. and introduces the roles social workers play in these systems. It focuses on the ETHICA model of ethical decision making as a resource and tool that can be used to help forensic social workers process difficult and complex situations across multiple systems.
This chapter explains the theoretical basis for motivational interviewing (MI). It reviews the empirical evidence for the use of MI with diverse populations in forensic settings. MI involves attention to the language of change, and is designed to strengthen personal motivation and commitment to a specific goal by eliciting and exploring the person’s own reasons for change within an atmosphere of acceptance and compassion. It is now internationally recognized as an evidence-based practice intervention for alcohol and drug problems. MI involves an underlying spirit made up of partnership, acceptance, compassion, and evocation. The chapter discusses four key processes involved in MI: engaging, focusing, evoking, and planning. It also describes five key communication microskills used throughout MI: asking open-ended questions, providing affirmations, offering summarizing statements, providing information and advice with permission, and reflective statements.
Recent advancements in molecular genetics have expanded our understanding of the etiology of many neurological diseases and neurodevelopmental abnormalities. Having a comprehensive understanding of genetics is essential in treating patients with metabolic epilepsies. Genetic counseling has been defined as a process of helping people understand and adapt to the medical, psychological, and familial implications of genetic contributions to disease. Some of the components of a genetic counseling interaction include interpretation of family and medical histories to assess the chance of disease occurrence or recurrence; education about inheritance, testing, management, prevention, resources, and research; and counseling to promote informed choices and adaptation to the risk or condition. The genetic counselor may also educate patients and their families about the underlying genetics of their epilepsy and the relevance of a genetic cause of epilepsy for family members, including recurrence risk, reproductive options and the possible teratogenic effect of antiepileptic drugs.Source:
This chapter presents a brief review of the enzymes, transporters, and cofactor producers of the urea cycle. Seizures have long been associated with urea cycle disorders (UCDs), thought to be caused by high levels of ammonia. Furthermore, the brain damage obtained during metabolic crisis has been thought to damage critical structures, leading to epilepsy after the conclusion of the crisis. The first and most critical step of successful treatment of UCDs is recognition. Neurologic monitoring is an essential part of the emergency management of UCDs. The neurological abnormalities observed in patients with urea cycle defects are vast. Controlling ammonia levels by dialysis and complementary medication are needed. EEG monitoring should be initiated early, as this may be very useful for clinical management and indication of untreated metabolic crises. Furthermore, aggressive treatment of clinical and subclinical seizure activity may be helpful in optimizing outcomes for these patients.Source:
This chapter explores recent insights from preclinical and clinical studies of cancer induced bone pain (CIBP). There are various neuropathic, nociceptive, and inflammatory pain mechanisms that contribute to CIBP. Neuropathic pain can be induced as tumor cell growth injures distal nerve fibers that innervate bone and pathological sprouting of both sensory and sympathetic nerve fibers. These changes in the peripheral sensory neurons result in the generation and maintenance of tumor induced pain. CIBP is usually described as dull in character, constant in presentation, and gradually increasing in intensity with time. A component of bone cancer pain appears to be neuropathic in origin as tumor cells induce injury or remodeling of the primary afferent nerve fibers that normally innervate the tumor bearing bone. The treatment of pain from bone metastases involves the use of multiple complementary approaches including radiotherapy, chemotherapy, surgery, bisphosphonates, and analgesics.
Cancer can affect the autonomic nervous system in a variety of ways: direct tumor compression or infiltration, treatment effects (irradiation, chemotherapy), indirect effects (e.g., malabsorption, malnutrition, organ failure, and metabolic abnormalities), and paraneoplastic/autoimmune effects. This chapter focuses on a diagnostic approach and treatment of cancer patients with dysautonomia, with an emphasis on immune-mediated autonomic dysfunction, a rare but potentially highly treatable cause of dysautonomia. Autonomic dysfunction can be divided into nonneurogenic (medical) and neurogenic (primary or secondary) causes. Orthostatic hypotension is a cardinal symptom of dysautonomia. The autonomic testing battery includes sudomotor, vasomotor, and cardiovagal function testing and defines the severity and extent of dysautonomia. Conditions encountered in the cancer setting that are associated with autonomic dysfunction include Lambert-Eaton Myasthenic Syndrome, anti-Hu antibody syndrome, collapsin response-mediator protein 5, subacute autonomic neuropathy, neuromyotonia (Isaacs’ syndrome), and intestinal pseudo-obstruction. The chapter describes various pharmacologic and nonpharmacologic therapies for treatment of orthostatic hypotension.
Despite treatment advances in the world of oncology, problems with sexuality, intimacy, and fertility persist for many women and men treated for cancer. Life expectancy of cancer patients, both young and old, has significantly increased due to advances in treatments of malignant diseases. Consequently, medical attention has expanded its focus to improving the quality of life of patients who have undergone cancer treatment. Sexual function and feeling healthy enough to be a parent represent two of the strongest predictors of emotional well-being in cancer survivors, and parenthood can represent a return to normalcy, contributing happiness and life-fulfillment. Often, cancer survivors fear that their disease or treatment history may adversely affect offspring conceived posttreatment, contributing risk for congenital anomalies, impaired growth and development, or even for malignancy. This chapter provides physical psychosocial spiritual dimensions of the fertility issues or symptom followed by its nonpharmacological and pharmacological treatment.
In human cancer, the role of genetic mutations, epigenetic alterations, and cellular repair mechanisms are becoming increasingly apparent. Recent studies have elucidated significant variations of the genetic codes that underpin cancer development in a variety of cancer subtypes. Genetic variations provide a backbone upon which cancer cells can adapt to overcome both intrinsic and extrinsic mechanisms designed to limit the growth of abnormal cells. This chapter provides an overview of the types of mutations, various epigenetic modifications, DNA repair mechanisms, and their relationship to the development of cancer, as well as various techniques utilized for the detection of these genetic alterations in cancer. With the development of new, advanced, and sensitive molecular techniques like next-generation sequencing and digital droplet polymerase chain reaction, our understanding of cancer biology is rapidly developing, and a critical appreciation and knowledge of these cancer-associated changes will likely lead to continued development of more effective therapies.
