Objective : Hyperhidrosis is a condition characterized by excessive sweating. Some studies suggest that hyperhidrosis is associated with autonomic nervous system dysfunction. Hyperhidrosis is often accompanied by hypersensitivity, tension, irritability, heat flashes, fatigue, etc. This study was designed to evaluate the correlation between Oriental Medicine diagnosis and the autonomic nervous system function in patients with hyperhidrosis using Heart Rate Variability (HRV) analysis. Methods : 23 palmar and plantar hyperhidrosis patients and 10 systemic hyperhidrosis patients were recruited and evaluated by Oriental Medicine diagnostic questionnaire and HRV analysis. The Oriental Medicine diagnostic questionnaire used a three-dimensional diagnosis that classified patients into Cold or Heat Syndrome, Yin or Yang Syndrome, and Deficiency or Excess Syndrome. Measured indices of HRV used the frequency domain analysis(i.e. TP, VLF, LF, HF and LF/HF ratio). Also, measure indices of HRV adjusted for aging effects were evaluated. Results : Cold/Heat Syndrome was not associated with hyperhidrosis prevalence nor the HRV analysis in hyperhidrosis patients. The Yang Syndrome group(78.8%) was more strongly correlated than the Yin Syndrome group(21.2%), and character of Yang was correlated with the adjusted TP and adjusted LF. The LF/HF ratio in the Excess Syndrome group was significantly higher than the LF/HF ratio in the Deficiency Syndrome group. Conclusion : Hyperhidrosis was not associated with the Cold/Heat Syndrome, but was found to be closely associated with the Yang Syndrome. The LF/HF ratio was significantly higher in the Excess Syndrome group than in the Deficiency Syndrome group in hyperhidrosis patients.

A 73-year-old man with progressive quadriparesis was diagnosed as Guillain-Barr$\acute{e}$ syndrome. On the 6th hospital day, the patient complained of sudden chest discomfort. The blood test and echocardiography suggested myocardial injury, and acute myocardial infarction was considered. However, coronary angiography displayed no vascular lesion, and the electrocardiography and echocardiogram showed marked improvement 14 days later. We concluded the patient had a reversible cardiomyopathy which is a rare complication of Guillain-Barr$\acute{e}$ syndrome.

Postural orthostatic tachycardia syndrome (POTS) refers to the presence of orthostatic intolerance with a heart rate (HR) increment of 30 beats per minute (bpm) or an absolute HR of 120 bpm or more. There are sporadic reports of the autonomic nervous system dysfunction in migraine and fibromyalgia. We report a case of POTS associated with migraine and fibromyalgia. The patient was managed with multidisciplinary therapies involving medication, education, and exercise which resulted in symptomatic improvement. We also review the literature on the association between POTS, migraine, and fibromyalgia.

Neuroleptic malignant syndrome (NMS) is an uncommon but potentially fatal idiosyncratic reaction to neuroleptics, characterized by muscular rigidity, fever, autonomic dysfunction, and altered consciousness. The major theories to explain NMS is central dopaminergic blockade, but it is unclear. Risperidone is a new antipsychotic drug, a benzisoxazole derivative that blocks dopamine $D_2$ receptor and serotonin type 2 receptor. The comparatively greater serotonin-blocking activity is believed to give risperidone the specific property of not causing any more extrapyramidal side effects than conventional antipsychotics at the optimal dose of 4-8mg/day. It is postulated that risperidone is unlikely to cause NMS. Here, we report a case of risperidone induced neuroleptic malignant syndrome.

Harlequin syndrome is a rare disorder of the sympathetic nervous system characterized by unilateral facial flushing and sweating. Although its etiology is unknown, this syndrome appears to be a dysfunction of the autonomic nervous system. To the best of our knowledge, thus far, very few reports on perioperative Harlequin syndrome after thoracic surgery have been published in the thoracic surgical literature. Here, we present the case of a 6-year-old patient who developed this unusual syndrome following the resection of a posterior mediastinal mass.

Chronic recurrent abdominal pain is a common manifestation in children. Functional abdominal pain is the most common cause of chronic abdominal pain and can be diagnosed properly by the physician without the requirement of specific evaluation when there are no alarm symptoms or signs. Functional abdominal pain is categorized as functional dyspepsia, irritable bowel syndrome, functional abdominal pain, abdominal migraine, and aerophagia, according to the Rome II criteria for pediatric functional gastrointestinal disorders. New concepts on the pathogenesis of functional abdominal pain include brain-gut interaction, visceral hypersensitivity, gastrointestinal dysmotility, inflammation, autonomic dysfunction, genetic predisposition, and triggering factors including psycho-social stress.

We describe a 44-year-old woman with paresthesia, fatigue, and palpitation, 10 days after human papillomavirus (HPV) vaccination. The quantitative sensory test showed abnormal detection threshold in her foot. Tilt test result indicated postural orthostatic tachycardia syndrome. Symptoms were improved after immunomodulating therapy, pain control drug, and oral beta blocker medication. This is first case report for small fiber neuropathy and autonomic dysfunction after HPV vaccination in Korea.

Complex regional pain syndrome (CRPS) is a chronic regional pain disorder that most frequently affects the limbs. It is characterized by hyperalgesia, allodynia, edema, motor disturbance, and vasomotor instability, and typically occurs following surgery or trauma. In type-I CRPS there is no confirmed nerve injury, while peripheral nerve injury is present in type-II CRPS. The multifactorial pathophysiological etiology of CRPS includes inflammation, autoimmune responses, abnormal cytokine production, autonomic dysfunction, altered blood flow, psychological factors, and central cortical reorganization. There are no specific laboratory diagnostic tools for CRPS, and so it is diagnosed clinically. The Budapest criteria are currently the most-accepted diagnostic criteria.

Occupational neurotoxic diseases have become increasingly common in Taiwan due to industrialization. Over the past 40 years, Taiwan has transformed from an agricultural society to an industrial society. The most common neurotoxic diseases also changed from organophosphate poisoning to heavy metal intoxication, and then to organic solvent and semiconductor agent poisoning. The nervous system is particularly vulnerable to toxic agents because of its high metabolic rate. Neurological manifestations may be transient or permanent, and may range from cognitive dysfunction, cerebellar ataxia, Parkinsonism, sensorimotor neuropathy and autonomic dysfunction to neuromuscular junction disorders. This study attempts to provide a review of the major outbreaks of occupational neurotoxins from 1968 to 2012. A total of 16 occupational neurotoxins, including organophosphates, toxic gases, heavy metals, organic solvents, and other toxic chemicals, were reviewed. Peer-reviewed articles related to the electrophysiology, neuroimaging, treatment and long-term follow up of these neurotoxic diseases were also obtained. The heavy metals involved consisted of lead, manganese, organic tin, mercury, arsenic, and thallium. The organic solvents included n-hexane, toluene, mixed solvents and carbon disulfide. Toxic gases such as carbon monoxide, and hydrogen sulfide were also included, along with toxic chemicals including polychlorinated biphenyls, tetramethylammonium hydroxide, organophosphates, and dimethylamine borane. In addition we attempted to correlate these events to the timeline of industrial development in Taiwan. By researching this topic, the hope is that it may help other developing countries to improve industrial hygiene and promote occupational safety and health care during the process of industrialization.

This study was performed to evaluate the effect of Kami-bun-sim-ki-eum on irritable bowel syndrome and to find the factors valuable to diagnosis of symptom-complex of them. Four major sympoms were classified in all 31 paients(female 17, male 14), which was index of abdominal, fecal, autonomic dysfunction, and gastric dysfucton and pain severity score method was used in monitoring with the effect of Kamibun-sim-ki-eum on irritable bowel syndrome before and after adminstration of 2 packs I day for 10 days. We have found that Kami-bun-sim-ki-eum was effective only in female group ,but not in male and only sex factor was recognized significantly among factors to have influenced the effect of Kami-bun-sim-ki-eum. Rate of improvement was mean 61% in female, accompanied with improvement of each symptom after administration. Therefore, we have concluded that Kami-bun-sim-ki-eum can be applyed as one of an choice medicines in treating female irritable bowel syndrone.
