OBJECTIVES: The aim of this study was to investigate the influences of affect states and mood congruent/incongruent variables in psychosis-proneness. METHODS: Five hundred and two undergraduate students completed the SPQ and other scales. Psychosis-proneness was measured by Schizotypal Personality Questionnaire (SPQ), and affect states were measured by Positive Affect and Negative Affect Schedule (PANAS). Mood congruent variables were measured by Mood reactivity in Mood Survey and Affect Intensity Measure (AIM), and mood incongruent variables were measured by Trait Meta-Mood Scale (TMMS), Emotional Inhibition and Aggression Control in Emotional Control Questionnaire (ECQ). RESULTS: By hierachical regression analysis, total 39.1% of SPQ total score variance was explained by emotion related variables. In detail, negative and positive affect states explained 26% of variance, and affect intensity and mood reactivity of mood-congruent variables added 7.7% and mood aware, emotional inhibition & aggression control among mood-incongruent variables added 5.5%. And emotion related variables explained 43.8% of negative symptom, 27.6% of positive symptom and 23.6% of disorganization score. CONCLUSION: Negative affect was revealed as important factor for psychosis-proneness, and positive affect acted as the reversed role. Mood reactivity and affect intensity acted as mood congruent variables which amplified and reinforced the influence of negative affect on psychosis-proneness. Mood aware, repair and aggression control acted as mood incongruent variables which modulated and reduce the influence of negative affect, while mood attention and emotional inhibition acted as mood congruent variables in contrast with the prediction.

BACKGROUND: Left ventricular hypertrophy(LVH) is a powerful indepedent risk factor of ventricular tachycardia and sudden death. Even though it is not clear the mechanism of sudden death in patients with LVH, inhomogenous ventricular repolarization is highly suggested. QT dispersion which reflecting regional inhomogeneity of repolarization is defined as interlead variation in QT intervals of 12 leads ECG. The purpose of this study was to assess whether QT dispersion is associated with LVH in hypertensive patients. METHODS: We assessed 23 untreated hypertensives with echocardiographic LVH and normal left ventricular systolic function. The criteria of 5th Joint National Committee stage I-III was used to define hypertension. Thirty four normotensives was assessed as controls. On a standard 12 lead ECG, the intervals between onset of QRS to end of T wave were measured(QT intervals) and corrected by heart rate(QTc). QT dispersion was calculated by the difference of maximal and minimal QTc. Left ventricular mass(LVM) was calculated from Devereux's formula using the parameters measured by the recommendation of American Society of Echocardiography. LVH was defined by LVM indices over 130 g/m2. RESULTS: LVM indices of hypertensive group were significantly greater than those of controls (162.2+/-39.3 g/m2 vs 84.2+/-16.1 g/m2, p<0.001). Maximal QT and QTc of hypertensive group were significantly prolonged than those of controls(maximal QT=401+/-31 ms vs 380+/-35 ms, p<0.05 ; maximal QTc=432+/-19 ms vs 414+/-17 ms, p<0.001). QT dispersions were significantly greater in hypertensive group than in controls(60.2+/-15.7 ms vs 33.2+/-11.7 ms, p<0.001). In hypertensive group, there was significant association between LVM index and QT dispersion(r=0.492, p=0.017). CONCLUSIONS: Hypertensives with LVH have a prolonged QT and QTc and increased QT dispersion in comparision with controls. QT dispersion in these patients correlates with degree of LVH.

Heterotopic pregnancy with coexistiong intrauterine and extrauterine pregnancy, is a rare event in natural pregnancy. However, in recent years, the increase in the incidence of pelvic inflammatory disease and use of assisted reproductive technology had led to an increase in the frequency of heterotopic pregnancy. When the diagnosis of heterotopic pregnancy is delayed, maternal mortality and morbidity may be increased, and unwanted loss of intrauterine pregnancy may occur. Therefore, the early diagnosis of heterotopic pregnancy is clinically important, and clinicians have to consider the possibility of heterotopic pregnancy and conduct careful and thorough evaluation if suspected. We experienced a case of heterotopic pregnancy in a woman in the absence of the known risk factors. She underwent underwent spontaneous abortion of intrauterine pregnancy at postoperative 4th day, after laparoscopic salpingectomy for left tubal pregnancy. We report this case with brief review of literature.

Data from clinical studies are needed for psychiatrists to make quick and scientific decisions based on the best available evidence in clinical settings. Various methods of clinical studies are useful for clinicians to have reliable answers to unmet clinical needs. Although randomized controlled trials may provide high-quality information about major issues, well-designed, naturalistic and observational studies often give us unbiased explanation for real-world phenomena. Adequate selection of clinical variables and appropriate number of participants are key factors of well-designed clinical studies. Statistical methods can add an extra dimension to initial design of clinical studies. Given ethical issues in clinical studies on psychiatric disorders, special regards should be paid to participants' ability to provide informed consents. New strategies of clinical studies need to be developed to meet clinical needs and protect the rights and welfare of study participants.

OBJECTIVES: This study investigated the patterns of psychotropic medications prescribed to patients admitted to an open psychiatric ward. METHODS: We reviewed 4282 medical records of patients who were discharged from an open psychiatric ward from May 2003 through April 2014. Data were collected on each patient's age, sex, length of hospital stay, number of past admissions, discharge diagnosis, and kinds and dosages of psychotropic medications at discharge. RESULTS: Among the 1384 male and 2898 female patients, 3.56 psychotropic medications were prescribed on average, with the number increasing across years, from 3.30 in 2003-2008 to 3.76 in 2009-2014. Prescription rates of antipsychotics, anxiolytics, and hypnotics significantly increased in patients with depressive disorders, bipolar disorders, anxiety disorders, delirium, dementia, and amnestic and other cognitive disorders. Only lithium prescription rates decreased significantly. Prescriptions for two or more anxiolytics and antipsychotics increased during the survey years, while antidepressant polypharmacy rates decreased. CONCLUSIONS: Recently, there has been a significant increase in the number of psychotropic medications prescribed, including antipsychotics, anxiolytics, and hypnotics. Caution should be exercised when prescribing medications to avoid cost increases and the risk of side effects, with uncertain gains in the quality of care.

BACKGROUND: The radial forearm flap is a versatile, widely used flap. However, the possibility of donor site complications has led to concern over its use. Some surgeons prefer using other flaps whose donor sites can be closed primarily with less morbidity, including avoiding unpleasant scarring. However, in our experience, donor site stability of the radial forearm flap can be reliably achieved by using well-implemented specific procedures. Here, we present a collection of donor site cases of the radial forearm flap and investigate factors that affect the aesthetic results as the basis for a reference for selecting a radial forearm flap. METHODS: In this retrospective study, we reviewed 171 cases in which a radial forearm flap was used for free tissue transfer after resecting head and neck cancer. We focused on donor site morbidity rates. Each operation involved a detailed procedure designed to minimize donor site morbidity. Moreover, statistical investigations were conducted for 22 cases to determine factors affecting the scar appearance. RESULTS: Only one case developed total skin graft necrosis as a major complication. Scar-related aesthetic results were acceptable, and the body-mass index, body weight, diabetes, and cardiac problems were significant factors related to the appearance of scars. CONCLUSIONS: Performing the radial forearm flap using a well-implemented detailed technique helps achieve acceptable donor site morbidity results. The aesthetic results were more promising for patients without excess body weight, diabetes, or cardiac problems. Therefore, anxiety about donor site morbidity should not be a reason to avoid selecting the radial forearm flap in suitable patients.
