Traumatic brain injury(TBI) used to be developed after a severe traumatic event. Therefore TBI usually induces acute or chronic stress reaction. I reviewed the concept, epidemiology, biological or psychosocial etiology, diagnosis and treatment of post-traumatic stress disorder (PTSD), and discussed about PTSD or stress reaction after TBI. Early evaluation and management of stress reaction after TBI are important.

In this article, we review the efficacy of early interventions after traumatic incidents and during acute stress disorder (ASD). There are some evidences that psychopharmacological medications such as propronolol, morphine, and hydrocortisone are effective in the prevention of posttraumatic stress disorder (PTSD). Considering the role of selective serotonin reuptake inhibitors in hippocampal neurogenesis and an animal model of PTSD, early administration of selective serotonin reuptake inhibitors is also fairly promising. Other pharmacological treatments including benzodiazepines did not treat ASD nor prevent PTSD. There are good evidences that cognitive behavioral therapy including cognitive therapy and prolonged exposure is a valuable intervention for ASD and the most effective prevention for PTSD. No contolled researches on eye movement desensitization&reprocessing, psychodynamic psychotherapy and hypnotherapy have performed. Recent randomized controlled studies using psychological debriefing did not prove as a useful intervention for the prevention of PTSD until now, although the efficacy of debriefing has been at the centre of controversy.

An epidemiologic investigation was carried out to determine the prevalence of symptoms of temporomandibular disorders in college students that aged 19-31 years. 460 students were investigated with a questionnaire from September to December 2006. The obtained results were as follows : 1. The prevalence of symptoms of temporomandibular disorders was 80.6%. 2. The most frequently complained symptom was headache and joint sound was the next one without distinct difference between men and women. 3. While the rate of occurrence of symptom of acute malocclusion decreased with age in men, that of TMJ pain during chewing or speech increased with age in women. 4. Symptoms including TMJ pain during mouth opening, chewing or speech, TMJ fatigue and acute malocclusion occurred significantly more frequently in women than in men. Contributing factors including resting cheeks on hands, stressful state, gum chewing, insomnia and clenching occurred significantly more frequently in women than in men. 5. There was a highly significant relationship between symptoms and contributing factors including resting cheeks on hands, stressful state, unilateral chewing, insomnia and clenching. 6. There was a highly significant relationship between symptoms and general personality.

Abnormal illness behavior in patients with somatoform disorders were known formed by their traditional disease concepts and somatization-prone socio-cultural factors. The authors evaluated the characteristics of abnormal illness behavior in patients with somatoform disorders(who had somatization) by using abnormal illness behavior questionnaire. Methods : 29 somatoform disorders(SD) and 57 disease controls were compared by clinical characteristics, severity of pain, state anxiety(by Spielberger's State & Trait Anxiety Inventory), depression(by Beck's Depression Inventory) and level of psychosocial stess(by DSM-III-R). The illness behavior was measured by illness Behavior Questionnaire(IBQ). Results SD group had longer period of somatic symptoms with less severity in pain. The degree of anxiety and depression were higher in SB compared with controls. However, the degree of psychosocial stress was almost same between both groups. In IBQ, SD showed higher scores in general hypochondriasis, disease conviction, and affective disturbance subscales compared to control group. Conclusion: High disease conviction and hypochondriacal nature revealed by IBQ seemed to be a role in making somatization by way of somatic focusing and hypervigilance. And those tended to lead patients visit hospital frequently and report various somatic complaints. Evaluating abnormal illness behavior in somatoform disorders would be not only helpful in understanding the natures of somatoform disorders but also useful differentiating SD with other psychiatric conditions.

Airborne particulate matter (PM) is an environmentally hazardous pollutant that originates from various sources. PM is comprised of solid particles and liquid droplets of diverse composition and size. Hazardous chemical compositions of PM include elemental and organic carbon, organic compounds, biological compounds and metals. Upon acute and chronic PM exposure, toxic contaminants enter and accumulate within physiological systems and prompt cell structure changes accompanied with intracellular endoplasmic reticulum stress, mitochondrial dysfunction, oxidative stress, inflammation, lipid accumulation, and cell cycle arrest. Ultimately, these cellular response leads to the development of key characteristics of aging. In addition, PM internalization enhances autophagy reflux and lysosomal dysfunction, which is involved in cell aging. Previous studies have emphasized a positive association between PM and increased mortality or decreased lifespan, although these are evidenced mostly by observational studies. Direct evidence of the link between PM and aging is still limited. This review evaluates the evidence from not only observational studies but also in vitro and in vivo evidence of PM on aging progression and age-related diseases development. This evidence is based on age-associated cellular changes including endoplasmic reticulum stress, mitochondrial dysfunction, oxidative stress, inflammation, adipose accumulation, autophagy, which strengthen the association between PM exposure and aging. Understanding the underlying cellular responses under PM may allow for the development of new therapeutic targets for PM-induced aging.

목장 경영의 성공과 실패에는 여러 가지 요인이 작용하지만 연중 얼마나 적은 소가 도태되는가 하는 것 또한 아주 중요하게 생각해 보아야 할 사항이다. 낙농에 있어 거의 대부분의 질병이 산욕기에 발병하는데 산욕기(産褥期)란 분만으로 인한 상처가 완전히 낫고, 자궁이 평상시 상태가 되며 신체의 각기관이 임신 전의 상태로 회복되기까지의 기간으로 대개 분만 후 6~8주간을 말한다. 산욕기에 주로 발생할 수 있는 다양한 질병(산욕기 부전마비, 난산, 급성유방염, 제4위 전위증 등)들이 조기에 발견되어 적절히 치료되지 못하고 만성화되면서 전해질불균형, 에너지와 단백질의 섭취부족에 의한 영양장애로 허약과 지방간 및 케토시스 등으로 진행되어 결국 도태됨으로서 목장 경영에 있어 막대한 영향을 끼치는 것이다. 이러한 산욕기 질병의 주 원인은 건유기 사양관리에 있다. 건유기간 동안 체점수(BCS)의 변화를 최대한 줄이면서 분만전의 스트레스를 얼마만큼 줄일 수 있도록 관리하는가에 달려있다. 다시말해 분만 전 마지막 한달간에 건유에서 분만으로의 이행과정을 얼마나 매끄럽게 연결 지어주는가에 따라 산욕기 질병의 발생률이 결정되는 것이다. 본 고에서는 건유기 사양관리 소홀로 발생되는 산욕기 부전마비에 관해서 자세히 설명해 보고자 한다.

This study investigated the responses of the autonomic nervous system of individuals with Type D personality during an acute stressful situation. Twenty-three female students of Type D personality and 23 female students with non-Type D personality. Stroop Color-Word Task was used to induce a stressful situation, heart rate variability (HRV) was used to measure the responses of the autonomic nervous system during the baseline, acute stress, recovery periods. To analyze the data, the repeated measures analysis of variance was used to compare the autonomic nervous system of the Type D group to that of the non-Type D group. Regression analysis is used to determine if the Type D scale and stress vulnerability predicted the activities of the autonomic nervous system during the baseline period. The results of this study demonstrated that the Type D group's normalized low frequency (LF norm) and ratio of low frequency to high frequency (LF/HF ratio) were higher than those for the non-Type D group, while its normalized high frequency (HF norm) was lower than that for the non-Type D group in all three periods. There were no statistically significant differences among the three periods in terms of LF norm, HF norm, and LF/HF ratio in the Type D group. The study demonstrated that the total scores of the Type DS-14 and scores of social inhibition and negative affect were independent predictors of LF norm and HF norm during the baseline. The Type D group showed increased activation of the sympathetic nervous system and/or decreased activation of the parasympathetic nervous system. These results support the hypothesis that the Type D personality is vulnerable to the stress. Also, the highly activated sympathetic and/or lowly activated parasympathetic nervous systems, which were observed in the Type D group during the baseline, indicated that the Type D individual is susceptible to psychosomatic disorders.

The psychological problems following the experiences of school-violence could be more important than the physical problems. Victims could suffer from fear, depression, anger, lowered self-esteem, suicidal thought, and personality changes. To study the risk factors for school violence and the psychiatric problems after the experiences to school-violence provide us important informations to prevent and solve the problems of school violence. We examined clinical characteristics and psychosocial backgrounds of 13 adolescents who visited the psychiatric clinic after exposures to school violence from September, 1996 to May, 1997. The clinical data included intensity, motivations, durations, and methods of violence, psychiatric symptoms following exposure, findings of psychological test, and treatment course. The socioeconomic data included developmental characteristics of subjects, family characteristics, school life, and peer relationships. Of the 13 adolescents who experienced exposure to violence, 8 have experienced chronic psychiatric disturbances, 5 experienced transient psychiatric symptoms such as anxiety, depression, suicidal attempt who eventually returned to home and school life. Of the 8 adolescents who experienced chronic psychiatric disturbances, 4 experienced PTSD and depression lasting 3-6 months more, otherwise 4 showed converted features, such as aggressive behavioral disorder or perpetrator by strong compensatory effects after psychological shock. The subjects who have experienced chronic psychiatric disturbance have clinical characteristics such as physical or emotional abuse, physical illness or handicap, defects of ego functionings, and lack of family support. In summary, victims by school-violence manifested serious psychiatric disturbances, and they had clinically significant risk factors and some of them became perpetrators of school-violence.

Objectives: The purpose of this case report was to propose Yangshimtang-Gamibang on three patients diagnosed with acute stress disorder. Methods: Yangshimtang-Gamibang was treated on three patients diagnosed with acute stress disorder after experiencing a traffic accident. The effects of Yangshimtang-Gamibang were evaluated through BAI (Beck Anxiety Inventory), NRS (Numerical rating scale), NDI (Neck Disability Index), ODI (Oswestry Disability Index), respectively, and quality of sleep was assessed with total sleep time and number of times waking up during sleep. Results: After the treatment, there was significant decrease in the value of BAI score, a measurement of anxiety, as well as the value of NRS, NDI, ODI, a measure of pain. Also, the sleep quality of three patients improved. Conclusions: The results indicate that Yangshimtang-Gamibang may have an effect on people with acute stress disorder who recently experienced a traffic accident.
