Gilles de la Tourette syndrome is a chronic motor and vocal tic disorder of childhood onset. Abnornmalities in basal ganglia-thalamo-cortical circuits may play an important role in the pathophysiology underlying the involuntary tics. It is often complicated by comorbid attention-deficit/hyperactivity disorder or obsessive-compulsive disorder. Transcranial magnetic stimulation(TMS) is a neurophysiologic technique with research ap-plication. As there is good evidence that this technique can modify cortical activity, repetitive TMS is also used for treatment to change the cortical excitability and therefore affect underlying interconnected cortical-sub-cortical loop. We reviewed the neurophysiologic parameters and the clinical applicability of TMS and rTMS.

Pre-eclampsia is a major cause of maternal and perinatal mortality and morbidity worldwide, but remains unclear about the underlying disease mechanisms. Pre-eclampsia is currently believed to be a two-stage disease. The first stage involves shallow cytotrophoblast invasion of maternal spiral arteriole, resulting in placental insufficiency. The hypoxic placenta release soluble factors, cytokines, and trophoblastic debris into maternal circulation, which induce systemic endothelial damage and dysfunction. This cause the second stage of the disease: maternal syndrome. Epidemiological research has consistently demonstrated a familial predisposition to pre-eclampsia. Intensive research efforts have been made to discover susceptibility genes that will inform our understanding of the pathophysiology of preeclampsia and that may provide direction for therapeutic or preventative strategies. In this review, we summarize the current understanding of the role of genetic factors in the pathophysiology of pre-eclampsia and explain the molecular approach to search for genetic clues in pre-eclampsia.

Purpose: Irritable bowel syndrome (IBS) is frequently yet little understood disease. Review was performed to promote understanding on the characteristics, pathophysiology, and risk factors of IBS. Content: IBS is characterized by abdominal discomfort associated with pain and altered bowel function; structural and biochemical abnormalities are absent. Generally IBS is more prevalent in women and people with higher educational and social background, but there are some controversies. IBS is diagnosed by the Rome II or Manning criteria after excluding organic gastrointestinal diseases. The pathophysioloy is explained by abnormal control mechanism of central and enteric nervous system. Mucosal immunity, secretions, and neurotransmitter are also associated with the hypersensitivity and motility change of bowel function. Stress is known as a major triggering factor and contributed to symptoms. Other risk factors are genetic elements, childhood experiences, inflammation, anxiety, depression, diet, and sleep disorders.

The clinical concept of coronary artery disease (CAD) has seen a paradigm shift over the last decade. CAD is mostly a progressive disease, and patients with CAD can develop acute coronary syndromes at any point in disease progression. In this clinical context, a new term, "chronic coronary syndrome," was published in the 2019 European Society of Cardiology guidelines, reflecting the importance of early diagnosis and active management. Recent advances have been made in the evaluation of CAD using coronary CT angiography (CCTA). The clinical usefulness of CCTA in patients with stable angina or chronic coronary syndrome begins with the detection of early asymptomatic CAD. The characterization of atherosclerotic plaque and its role in determining treatment strategies for CAD have been demonstrated for all stages of the disease. This review describes the pathophysiology of stable angina to aid in the understanding of the clinical applications of CCTA.

Burning mouth syndrome(BMS) is a chronic oral pain and a symptom complex disorder usually unaccomplished by mucosal lesion or other clinical and laboratory signs of organic disease. BMS is characterized by a spontaneous burning sensation that mainly affects middle-aged and postmenopausal women. The etiology of BMS is poorly understood even though evidence for a possible neuropathic pathogenesis. BMS cause from various local or systemic factor, including nutritional deficiencies, hormonal change, local infection, dental procedure, dry mouth, medication and systemic disease including diabetes mellitus. Many studies suggest peripheral alteration in sensory of trigeminal nerve system. BMS patients with supertaster indicates pathologies of central and peripheral nerve system induced by an alteration in the taste system at the level of chorda tympani and glossopharyngeal nerve. The author discuss our current understanding of etiology and pathogenesis of BMS that refered chronic oral pain.

Although obsessive-compulsive disorder(OCD) affects children, adolescents, and adults whether its juvenile(dhild and adolescent) and adult forms are different subtype of a disorder remains unknown. But there are increasing findings that suggest that juvenile OCD may be unique subtype of the disorder. One proposed subtype is the childhood OCD associated with high comorbidity of tic disorder and increased familial loading for OCD or tic disorder. The other proposed subtype is the childhood OCD and/or tic disorder occuring in association with streptococcal infection(PANDAS). These two subtypes of OCD are unlikely to respond to SSRI due to possible different pathphysiological mechanism. So this paper reviews the characteristics of OCD and therapeutic approaches for treatment resistant OCD in childhood and adolescence. Considering the likely heterogeneity of OCD, the possibility that juvenild OCD may be a variant of the disorder can have important clinical and scientific implications because it may further our understanding of this disorder, its etiology, and perhaps its treatment.

Hepatitis B virus (HBV)는 전 세계적으로 약 3억 5천만 명이 만성적으로 보균하고 있으며, 한국에서도 보건의학적으로 가장 중요하여 높은 간암의 발병율과도 밀접한 관련이 있다. 최근에 와서 HBV가 유도하는 임상적 위험질환의 병태생리에 대해서 면역학적 지식의 발전을 바탕으로 이해가 깊어졌는데, 바이러스 자체보다는 인체의 다양한 면역반응이 질병의 경과에 더욱 중요하다. 이러한 사실로 한의학적 치료법의 과학적 연구는 만성 HBV 보균자들에게 효과적인 치료방법으로 적용될 것으로 기대될 수 있는데, 우선 여기서는 전형적으로 HBV와 관련해서 의학적 문제를 모두 가지고 있는 한 가족을 통해서 HBV에 대한 폭넓은 이해에 도움을 얻고자한다.

The chronic fatigue immune dysfunction syndrome (abbreviated CFIDS or CFS) is a disorder characterized by debilitating fatigue(over 6 months.), along with cognitive, musculoskeletal, and sleep abnormalities. The etiology of this illness is unlikely to be a single agent. Findings to date suggest that physiological and psychological factors work together to predispose and perpetuate the illness. Diagnosis is made difficult by the nonspecific clinical findings and no available diagnostic testing. With no known cause or cure for the chronic fatigue and immune dysfunction syndrome, treatment is based on relieving symptoms and improving the quality of life of affected patients. There is emerging evidence that chronic fatigue syndrome may be familial. In the future, studies will examine the extent to which genetic and environmental factors play a role in the development of chronic fatigue syndrome. Most patients with CFS have psychiatric problems such as a generalized anxiety disorder, or major or minor depression, therefore, these mental health disorders may be correlated with the pathophysiology of the CFS. The treatment for CFS must be individualized, due to the heterogeneity of the CFS population. Also the treatment of CFS is built on a foundation of patient-physician relationship, respect and advocacy.

Purpose: The purpose of this study was to investigate and compare the level of importance, difficulty, satisfaction, and needs of biological nursing science courses-pathophysiology and pharmacology- among students of Advanced Practice Nursing Programs. Methods: A cross-sectional descriptive study using a self-report questionnaire has been adopted. Participants in this survey were 436 graduate students enrolled in an Advanced Practice Nursing Program. Using SPSS WIN 18.0 program, descriptive statistics, chi-square test, and t-test were conducted. Results: In a pathophysiology course, the students taught by nurse lecturers presented a higher level of importance and satisfaction than those were taught by non-nurse lecturers, but the difference was not significant statistically. In a pharmacology course, the students were taught by nurse lecturers expressed a higher level of satisfaction than those were taught by non-nurse lecturers, but the difference was not significant statistically. The students wanted to improve the quality of courses. Conclusion: According to the findings of this study, we should try to improve the quality of classes and to increase the number of courses taught by nurse-lecturers.
