Background Sexualized drug use or “chemsex” in Taiwan commonly incorporates the use of methamphetamine. Our study aimed to assess the extent of severity of dependence of methamphetamine among MSM in Taiwan as well as motivations for engagement in chemsex. Methods Direct messages were sent to users of a large MSM social networking application in Taiwan between November 2018 and January 2019. MSM who had at least one experience of using drugs during sex in the preceding 12 months were invited to complete an online survey that assessed their sexual behavior, substance use and motivations for engaging in chemsex. The Severity of Dependence Scale was used to assess methamphetamine dependency. Multivariable logistic regression was used to determine the factors associated with methamphetamine dependency. Results From a total of 1906 responses, 517 had used methamphetamine in their lifetime and were included in the analysis. The majority (87.2%) used more than one substance when engaging in chemsex in the past six months, while a quarter reported injection of methamphetamine within the last six months. The most commonly reported motivations for participants to engage in chemsex were to have fun, for relaxation, and to increase the intensity of the sexual experience. Nearly half (46.0%) exhibited signs of methamphetamine dependency. Lower monthly income, injection of methamphetamine, ever feeling lonely in the past 3 months and concerns about their substance use expressed by others were significantly associated with methamphetamine dependency. Conclusion A high proportion of MSM population who engaged in chemsex were at risk of developing methamphetamine dependency. While motivations for engaging in chemsex were diverse and suggest potential for enhanced sexual experience for some, community health organization for gay men's health and healthcare providers should be vigilant at identifying the risk of methamphetamine dependency and provide in-time, brief intervention or referrals when needed.

BACKGROUND AND OBJECTIVES Previous studies have revealed that the electroacupuncture or auricular-point pressure as a single treatment approach is beneficial for relieving insomniac symptoms among patients under methadone maintenance treatment (MMT). This study is designed to evaluate the clinical efficacy of combining two treatments. METHODS This study was a randomized, controlled, crossover trial. A total of 50 participants were recruited from the Linsen Chinese Medicine and Kunming Branches of Taipei City Hospital and randomly assigned to Groups A (25 participants) and B (25 participants). In Group A (electroacupuncture at the Hegu point (LI4) and Zusanli point (ST36) and auricular-point pressure on the Shenmen point) and Group B (only auricular-point), the interventions were implemented biweekly for 4 weeks. After a 1-week washout period, a crossover of the groups was performed. Sleep quality, according to the Pittsburgh Sleep Quality Index (PSQI), and daily attendance rate of MMT were evaluated. RESULTS Combined therapy significantly improved sleep quality, especially in the PSQI subscales of subjective sleep quality (60.91% vs 20.93%, P

The switch from methadone to buprenorphine-naloxone for individuals with heroin dependence is associated with several obstacles and challenges. Such patients may experience discomfort from discontinuing methadone, precipitated withdrawal symptoms induced by buprenorphine-naloxone, and poor psychosocial adjustments such as anticipatory anxiety regarding severe opioid withdrawal. We herein describe a 46-year-old man with a history of heroin dependence who underwent Traditional Chinese Medicine (TCM)-facilitated switching from methadone to buprenorphine-naloxone. No precipitated withdrawal was induced by buprenorphine-naloxone. The drug-switching process was successful and smooth. He maintained abstinence from heroin for the following year. In this case, we applied TCM for enhancement of methadone metabolism and detoxification, analgesic effects, and anxiolytic and hypnotic effects during the drug switch. We observed that TCM effectively facilitated the switch from methadone to buprenorphine-naloxone in our case. Further studies regarding TCM-facilitated treatment for heroin dependence should be conducted.

ADHD comorbidity has been associated with delayed diagnosis of ASD, but no study has investigated this association in an Asian country. Children with ASD were included and divided into three groups: ADHD before ASD, ADHD same/after ASD, and ASD only. Timing of ASD and ADHD diagnoses were assessed. The logistic regression model was performed to investigate the likelihood of being diagnosed with ASD after 6 years of age between three groups. ADHD before ASD (OR 10.93) group was more likely to being diagnosed with ASD after 6 years of age compared with ADHD same/after ASD (OR: 1.37) and ASD only groups. ADHD comorbidity would delay the diagnosis of ASD in the general clinical settings in Taiwan.

BackgroundAttention-deficit hyperactivity disorder (ADHD) increases the risk of suicidal behaviours through psychiatric comorbidities; however, a significant direct association has not been observed between ADHD and suicide attempts.AimsTo evaluate the risk of suicide attempt in adolescents and young adults with ADHD.MethodUsing a nationwide, population-based insurance claims database, this longitudinal cohort study enrolled 20 574 adolescents and young adults with ADHD and 61 722 age- and gender-matched controls between 2001 and 2009. Any suicide attempt was identified from enrolment to 31 December 2011. The association between ADHD medications and the likelihood of suicide attempt was assessed.ResultsADHD was an independent risk factor for any suicide attempt (hazard ratio = 3.84, 95% CI = 3.19–4.62) and repeated suicide attempts (hazard ratio = 6.52, 95% CI = 4.46–9.53). Subgroup analyses of men, women, adolescents and young adults demonstrated the same trend. Methylphenidate or atomoxetine treatment did not increase the risk of suicide attempt or repeated suicide attempts. Long-term methylphenidate treatment was associated with a significantly decreased risk of repeated suicide attempts in men (hazard ratio = 0.46, 95% CI = 0.22–0.97).ConclusionADHD was a risk factor for suicide attempt and a stronger predictor of repeated suicide attempts, independent of comorbidities. Further investigation is warranted to explore the mechanism underlying the association between ADHD and suicidal behaviours.Declaration of interestNone.

OBJECTIVE Several cross-sectional studies have reported a relationship between posttraumatic stress disorder (PTSD) and epilepsy. However, the temporal association between PTSD and epilepsy has rarely been investigated. We hypothesized that the risk of developing epilepsy later in life would be higher in patients with PTSD than in those without PTSD. METHODS Using the Taiwan National Health Insurance Research Database, 6425 individuals with PTSD and 24,980 age-/sex-matched controls were enrolled between 2002 and 2009 in our study and followed up to the end of 2011. Those who developed epilepsy during the follow-up period were identified. RESULTS Individuals with PTSD had a higher incidence of developing epilepsy (2.65 versus 0.33 per 1000 person-years, p < .001), with an earlier onset of epilepsy (37.53 years [15.80 years] versus 48.11 years [23.97 years], p = .002) than did the controls. Individuals with PTSD had an elevated risk of developing epilepsy (hazard ratio [HR] = 3.72, 95% confidence interval [CI] = 2.27-6.11) during the follow-up after adjustment for demographic data and medical and psychiatric comorbidities. Sensitivity analyses after excluding the observation in the first year (HR = 2.53, 95% CI = 1.44-4.47) and the first 3 years (HR = 2.14, 95% CI = 1.15-4.01) revealed consistent results. CONCLUSIONS These results supported a temporal association between PTSD and the development of epilepsy. Further studies are warranted to investigate the underlying pathophysiological pathways that explain the longitudinal association of PTSD with subsequent epilepsy.

Objective. To evaluate the clinical efficacy of combining electroacupuncture with auricular point pressing in improving quality of life of individuals with heroin use disorder undergoing methadone maintenance treatment. Design. A randomized controlled crossover trial. Subjects. 50 participants were recruited from Taipei City Hospital, Linsen Chinese Medicine and Kunming branches, and randomly allocated to treatment groups. Method. The 36-Item Short Form Health Survey (SF-36) was used. Group A received electroacupuncture at the Hegu (LI4) and Zusanli (ST36) and auricular point pressing on Ear Shenmen, and Group B received only auricular point pressing on Ear Shenmen biweekly for 4 weeks. After a 1-week washout period, crossover of the groups was performed. Results. The SF-36 mental component scores of the combined treatment group improved relative to the single treatment group (11.09 vs. 10.33, p=0.023). Methadone dosage was reduced in both groups (combined therapy group: 8.58 ± 4.17/7.76 ± 4.11 (baseline/posttreatment) vs. single therapy group: 8.36 ± 4.20/8.30 ± .28, p=0.001). Conclusion. Combined therapy of high-frequency electroacupuncture with auricular point pressing had better efficacy in enhancing quality of life, especially for mental well-being, and in gradually reducing methadone dosage.

BACKGROUND Evidence has shown a significant association between bipolar disorder and prevalence of risky sexual behaviors. However, the relationship between bipolar disorder and risk for sexually transmitted infections (STIs) requires further investigation, as do the effects of bipolar disorder medications on STI risk. METHODS In the present study, data from 26,028 adolescents and young adults with bipolar disorder (ICD-9-CM code 296 except 296.2x, 296.3x, 296.9x, and 296.82) and 104,112 age- and sex-matched non-bipolar-disorder controls from 2001 to 2009 were selected from the Taiwan National Health Insurance Research Database. Patients who contracted any type of STI-including human immunodeficiency virus, syphilis, genital warts, gonorrhea, chlamydial infection, and trichomoniasis-during the follow-up period (from enrollment to the end of 2011) were identified. RESULTS Cox regression analysis with full adjustment for demographic data, psychiatric comorbidities, and bipolar disorder medications showed that bipolar disorder was an independent risk factor (hazard ratio [HR] = 4.11; 95% confidence interval [CI], 3.62-4.66) for contracting an STI. Patients with bipolar disorder and substance and/or alcohol use disorders were at highest risk of STI occurrence. Long-term use of mood stabilizers (HR = 0.54; 95% CI, 0.34-0.86) and atypical antipsychotics (HR = 0.82; 95% CI, 0.71-0.95) was associated with reduced risk for contracting STIs. CONCLUSIONS Adolescents and young adults with bipolar disorder exhibited an increased risk of subsequent STI during the follow-up period compared with those without bipolar disorder. Comorbidity of substance and alcohol use disorders further increased this risk. Long-term use of bipolar disorder medications (mood stabilizers and atypical antipsychotics) may reduce this risk.

Objective To assess the independent or comorbid effect of conduct and mood disorders on the risk of suicide. Study design The Taiwan National Health Insurance Research Database was used to derive data for 3711 adolescents aged 12-17 years with conduct disorder and 14 844 age- and sex-matched controls between 2001 and 2009. The participants were followed up to the end of 2011, and those who attempted suicide during the follow-up period were identified. Results Adolescents with conduct disorder had a higher incidence of suicide (0.9% vs 0.1%; P .001) and attempted suicide at a younger age (17.38 ± 2.04 vs 20.52 ± 1.70 years of age) than did the controls. The Cox proportional hazards regression model, after adjustment for demographic data and psychiatric comorbidities, determined that conduct disorder was an independent risk factor for subsequent suicide attempts (hazard ratio, 5.17; 95% CI, 2.29-11.70). The sensitivity after those with other psychiatric comorbidities were excluded revealed a consistent finding (hazard ratio, 10.32; 95% CI, 3.71-28.71). Discussion Adolescents with conduct disorder had an increased risk of suicide attempts over the next decade. Future studies are required to clarify the underlying pathophysiology and elucidate whether prompt intervention for conduct disorder could reduce this risk.

Background Previous studies have suggested that the unaffected siblings of patients with attention-deficit hyperactivity disorder (ADHD) experience deficits in attention, impulsivity control, and behavior inhibition, which are associated with health-risk behaviors. However, risks to mental and physical health among the unaffected siblings of ADHD probands have rarely been investigated. Methods Using the Taiwan National Health Insurance Research Database, 5128 unaffected siblings of ADHD probands born between 1980 and 2000 were included in our study along with 20,512 age- and sex-matched controls, and they were followed from 1996 or birth until the end of 2011. Mental and physical health risks, including affective disorders, traumatic brain injury (TBI), and sexually transmitted infection were identified during the follow-up period. Results Logistic regression analyses with adjustments for demographic data showed that the unaffected siblings were more likely to develop unipolar depression (odds ratio [OR]: 1.76, 95% confidence interval [CI]: 1.39–2.22), bipolar disorder (OR: 2.10, 95% CI: 1. 09–4.05), and TBI (OR: 1.24, 95% CI: 1.14–1.36) than were the control group. Discussion The unaffected siblings of patients with ADHD were prone to developing unipolar depression, bipolar disorder, and TBI later in life.

Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are both frequently comorbid with other psychiatric disorders, but the comorbid effect of ASD and ADHD relative to the comorbid risk of other psychiatric disorders is still unknown. Using the Taiwan National Health Insurance Research Database, 725 patients with ASD-alone, 5694 with ADHD-alone, 466 with ASD + ADHD, and 27,540 (1:4) age-/gender-matched controls were enrolled in our study. The risk of psychiatric comorbidities was investigated. The ADHD + ASD group had the greatest risk of developing schizophrenia (hazard ratio [HR]: 95.89; HR: 13.73; HR: 174.61), bipolar disorder (HR: 74.93; HR: 19.42; HR: 36.71), depressive disorder (HR: 17.66; HR: 12.29; HR: 9.05), anxiety disorder (HR: 49.49; HR: 50.92; HR: 14.12), disruptive behavior disorder (HR: 113.89; HR: 93.87; HR: 26.50), and tic disorder (HR: 8.95; HR: 7.46; HR: 4.87) compared to the ADHD-alone, ASD-alone, and control groups. Patients with ADHD + ASD were associated with the greatest risk of having comorbid bipolar disorder, depressive disorder, anxiety disorder, disruptive behavior disorder, and tic disorder. The diagnoses of ASD and ADHD preceded the diagnoses of other psychiatric comorbidities. A comprehensive interview scrutinizing the psychiatric comorbidities would be suggested when encountering and following patients with both ASD and ADHD in clinical practice.

Background: Patients with psychiatric disorders have high cigarette smoking-related morbidity and mortality. Varenicline, a α4β2 nicotinic acetylcholine receptor (nAChR) partial agonist, has been approved for smoking cessation, but few studies compared the efficacy between the smokers with and without different psychiatric disorders. Methods: Smokers aged more than 20 years with a daily cigarette consumption of more than 10 cigarettes/ or a Fagerstrom Test for Nicotine Dependence Scale (FTND) score of more than 4 were enrolled. The efficacy of smoking cessation and adverse effects were compared between the smokers with and without psychiatric disorders after 12-week varenicline treatment. Results: In total, 140 smokers were recruited, of whom 94 (67.1%) had psychiatric disorders, including schizophrenia (n=19), bipolar disorder (n= 29), depressive disorder (n=31), or other psychiatric disorders (n =15). Compared with the smokers without psychiatric disorders, those with psychiatric disorders were significantly more likely to be women, younger, have a shorter smoking history and a higher FTND score (all p

Previous studies suggested that patients with attention-deficit hyperactivity disorder (ADHD) were prone to health-risk behaviors and accidents. However, the relationship of ADHD with the risk of traumatic brain injury (TBI) remained uncertain.Using the Taiwan National Health Insurance Research Database, 72,181 children (aged 3-11 years), adolescents (12-17 years), and young adults (18-29 years) with ADHD and 72,181 age-/sex-matched controls were enrolled between 2001 and 2009, and followed up to the end of 2011 in our study. Those who developed any TBI during the follow-up period were identified.Children, adolescents, and young adults with ADHD had a higher incidence of developing any TBI (9.8% vs. 2.2%, p.001), such as skull fracture (.2% vs. .1%, p.001) and concussion (4.3% vs. 1.0%, p.001), than the controls did. Cox regression analysis with the adjustment of demographic data, psychiatric comorbidities, and ADHD medications showed that ADHD was related to an increased risk of subsequent TBI (hazard ratio: 4.57, 95% confidence interval: 4.31-4.85), and indicated that long-term use of ADHD medication was associated with a reduced likelihood of subsequent TBI (hazard ratio: .93, 95% confidence interval: .87-.99).Patients with ADHD had an increased risk of developing any TBI compared with the controls. Long-term use of ADHD medications would reduce this risk. Our findings suggested that the public health government and clinicians should pay more attention to the TBI risk among patients with ADHD, and further indicated the importance of the optimal treatment for ADHD.

Herpes zoster results from reactivation of the endogenous varicella zoster virus infection. Previous studies have shown that herpes zoster and postherpetic neuralgia were associated with anxiety, depression, and insomnia. However, no prospective study has investigated the association between herpes zoster and the development of depressive disorder.Subjects were identified through the Taiwan National Health Insurance Research Database. Patients 18 years or older with a diagnosis of herpes zoster and without a psychiatric history were enrolled in 2000 and compared with age-/sex-matched controls (1:4). These participants were followed up to the end of 2010 for new-onset depressive disorder.A total of 1888 patients with herpes zoster were identified and compared with 7552 age-/sex-matched controls in 2000. Those with herpes zoster had a higher incidence of developing major depression (2.2% versus 1.4%, p = .018) and any depressive disorder (4.3% versus 3.2%, p = .020) than did the control group. The follow-up showed that herpes zoster was an independent risk factor for major depression (hazard ratio = 1.49, 95% confidence interval = 1.04-2.13) and any depressive disorder (hazard ratio = 1.32, 95% confidence interval = 1.03-1.70), after adjusting demographic data and comorbid medical diseases.This is the first study to investigate the temporal association between herpes zoster and depressive disorder. Further studies would be required to clarify the underlying pathophysiology about this association and whether proper treatment of herpes zoster could decrease the long-term risk of depressive disorder.

BACKGROUND Previous studies reported a high prevalence of depression among patients with autism spectrum disorder (ASD) and suggested a relationship between ASD and suicidality. However, whether ASD independently increases the risk of attempted suicide regardless of depression has not been determined. METHODS Using the Taiwan National Health Insurance Research Database, 5,618 adolescents aged 12-17 years and young adults aged 18-29 years with ASD (ICD-9-CM code: 299) and 22,472 age- and sex-matched controls were enrolled between 2001 and 2009 and followed to the end of 2011. Any suicide attempt was identified during the follow-up period. RESULTS Patients with ASD had a higher incidence of suicide attempts (3.9% vs 0.7%, P < .001) than did those without ASD. Both adolescents (HR = 5.79; 95% CI, 3.98-8.41) and young adults (HR = 5.38; 95% CI, 3.58-8.06) with ASD were more likely to attempt suicide in later life after adjusting for demographic data and psychiatric comorbidities. Sensitivity analyses after excluding the first year (HR = 4.52; 95% CI, 3.39-6.03) or first 3 years (HR = 3.36; 95% CI, 2.40-4.70) of observation showed consistent findings. CONCLUSIONS Patients with ASD had an increased risk of suicide attempts compared with those without ASD. ASD was an independent risk factor of attempted suicide. Further studies are needed to clarify the underlying pathophysiology between ASD and suicidality and to elucidate whether prompt intervention for ASD may reduce this risk.

Objectives Previous studies suggested a relationship between posttraumatic stress disorder (PTSD) in the specific population (i.e., war survivors and veterans) and subsequent dementia risk. However, whether patients with PTSD in the general population were at an increased risk for developing dementia in later life remained unclear. Methods The Cox regression analysis was performed using data from the Taiwan National Health Insurance Research Database. The study sample comprised 1750 patients diagnosed with PTSD between 2001 and 2009 and 7000 age-/sex-matched individuals without PTSD. Those who developed dementia during follow-up to the end of 2011 were identified. Results After adjusting for demographic data and medical and psychiatric comorbidities, PTSD was an independent risk factor for the risk for subsequent dementia (hazard ratio [HR]=4.37; 95% confidence interval [CI]: 2.53–7.55). There was a dose-dependent relationship between PTSD severity indicated by the frequency of psychiatric clinics visiting of PTSD (times per year) and the risk of subsequent dementia ( 10: HR: 18.13, 95% CI: 9.13–36.00). Furthermore, patients with depressive disorder and medical comorbidities, such as cerebrovascular diseases, diabetes mellitus, and head injuries, exhibited a higher risk for developing dementia. Discussions Our study suggested a significant dose-dependent association between PTSD and its severity and an increased risk of developing dementia later in life. The importance of mental care for trauma victims would increase in the coming century, and our findings broadened another era for the end result of a widely prevalent psychiatric disorder.

Backgrounds Previous studies have found an increased prevalence of atopic diseases among patients with major depression and bipolar disorder. But the temporal association between atopic diseases in adolescence and the subsequent risk of developing mood disorders has been rarely investigated. Methods Using the Taiwan National Health Insurance Research Databases, 5075 adolescents with atopic diseases (atopic cohort) and 44,729 without (non-atopic cohort) aged between 10 and 17 in 2000 were enrolled into our study and followed to the end of 2010. Subjects who developed major depression or bipolar disorder during the follow-up were identified. Results The atopic cohort had an increased risk of developing major depression (HR: 2.45, 95% CI: 1.93~3.11) and bipolar disorder (HR: 2.51, 95% CI: 1.71~3.67) compared to the non-atopic cohort, with a dose-dependent relationship between having a greater number of atopic comorbidities and a greater likelihood of major depression (1 atopic disease: HR: 1.80, 95% CI: 1.29~2.50; 2 atopic comorbidities: HR: 2.42, 95% CI: 1.93~3.04;≥3 atopic comorbidities: HR: 3.79, 95% CI: 3.05~4.72) and bipolar disorder (HR: 1.40, 95% CI: 0.57~3.44; HR: 2.81, 95% CI: 1.68~4.68; HR: 3.02, 95% CI: 1.69~5.38). Discussion Having atopic diseases in adolescence increased the risk of developing major depression and bipolar disorder in later life. Further studies may be required to clarify the underlying mechanism between atopy and mood disorders, and to investigate whether prompt intervention may decrease the risk of subsequent mood disorders.

LGBT (lesbian, gay, bisexual, transgender) patients suffer from stigma and discrimination when seeking healthcare. A large LGBT healthcare survey revealed that 56% of gay patients and 70% of transgender patients suffered some type of discrimination while seeking healthcare in 2014. The fostering of LGBT-friendly healthcare services is not just an advanced step of gender mainstreaming but also a fulfillment of health equality and equity. Additionally, LGBT-friendly healthcare services are expected to provide new opportunities for healthcare workers. Therefore, proactive government policies, education, research, and clinical practice should all encourage the development of these healthcare services. We look forward to a well-developed LGBT-friendly healthcare system in Taiwan.建構多元性別友善的醫療服務多元性別屬於社會當中的性少數，長期因為污名與歧視的存在，造成了多元性別就醫者在醫療環境中的困擾與不便。美國2014年的大規模調查顯示，56%的同志就醫者以及70%的跨性別就醫者曾在醫療場合中遭受歧視。建構多元性別有善的醫療環境，不但是性別主流化進階的具體實體，更是健康人權的落實。一個能夠落實多元性別友善的社會，更可以反映出社會對於弱勢與少數的包容與接受程度，也代表著尊重與彈性。從日益精緻化的醫療轉型角度來看，隨著多元性別友善的整體氛圍逐漸落實，背後亦充滿了龐大的醫療商機與更為多元的醫療照護型態的轉變。因此，本文由看見多元性別開始，從政策面、空間營造、臨床問診、以及教育研究各面向談起，從台灣本土角度結合許多重要的世界趨勢，探討建構多元性別友善醫療服務以及多元性別友善護理的具體方法。

Introduction. Benzodiazepines (BZDs) and zolpidem, zopiclone, and zaleplon (Z-drugs) are commonly prescribed to HIV-infected patients. We hypothesized that frequent BZD and Z-drug use among these patients may be associated with psychiatric illnesses, particularly in long-term users.Methods. We included 1,081 patients with HIV between 1998 and 2011 from the Taiwan National Health Insurance Research Database and matched them according to age, sex, and comorbidity with uninfected controls to investigate the psychiatric diagnoses and prescriptions of BZDs and Z-drugs. Cumulative defined daily dose (cDDD) was assessed as the indicator of the duration of medication exposure. Patients exhibiting a cDDD exceeding 180 were defined as long-term users.Results. The patients with HIV had an increased risk of any use (odds ratio (OR): 8.70, 95% confidence interval (CI): 6.82–10.97) and long-term use (OR: 5.06, 95% CI: 3.63–7.04) of BZD and Z-drugs compared with those without HIV during the follow-up after demographic data and psychiatric comorbidities were adjusted.Conclusion. A large proportion of the HIV-infected patients received prescriptions of BZDs and Z-drugs. Mood disorders, insomnia, anxiety disorders, HIV infection, and substance use disorder were substantial predictors among the BZD and Z-drug users. These findings suggest that providing psychiatric services for HIV-infected patients is vital.

This study investigated a 51-year-old married man with a history of heroin dependence who underwent methadone maintenance treatment for 7 years. He received traditional Chinese medicine (TCM)-facilitated treatments and switched from methadone to buprenorphine/naloxone. Strong anxiety symptoms were observed during the initial stage; therefore, we prescribed a combination of Chaihu-Shugan-San, Zhi Bai Di Huang and Chin-Gin-Kuan-Ming decoction as the major herbal synergic regimen to relieve the symptoms of opioid withdrawal, anxiety and insomnia. During the treatment course, no precipitating withdrawal syndromes were noted, and the subject was gradually relieved of his anxiety symptoms through continual TCM treatments. In conclusion, TCM is effective in facilitating the switch from methadone to buprenorphine/naloxone and relieving anxiety symptoms. Therefore, focus on TCM-facilitated treatments for heroin dependence should be increased.

Background Online gaming technology has developed rapidly within the past decade, and its related problems have received increasing attention. However, there are few studies on the psychiatric symptoms associated with excessive use of online games. The aim of this study is to investigate the characteristics of online gamers, and the association between online gaming hours, social phobia, and depression using an internet survey. Methods An online questionnaire was designed and posted on a popular online game websites, inviting the online gamers to participate the survey. The content of the questionnaire included demographic data, profiles of internet usage and online gaming, and self-rating scales of Depression and Somatic Symptoms Scale (DSSS), Social Phobia Inventory (SPIN), and Chen Internet Addiction Scale (CIAS). Results A total of 722 online gamers with a mean age of 21.8 ± 4.9 years completed the online survey within one month. 601 (83.2%) participants were male, and 121 (16.8%) were female. The mean weekly online gaming time was 28.2 ± 19.7 hours, which positively associated with history of online gaming (r = 0.245, p Conclusion The online gamers with longer weekly gaming hours tended to have a longer history of online gaming, and more severe depressive, social phobic, and internet addiction symptoms. Female online gamers had fewer weekly online gaming hours and a shorter previous online gaming history, but tended to have more severe somatic, pain, and social phobic symptoms. The predictors for depression were higher social phobic symptom, higher internet addiction symptoms, longer online gaming hours, and female gender.

A previous survey had shown a high level of psychiatric morbidity among human immunodeficiency virus (HIV)-infected individuals, but the number of patients that are actually identified as having a psychiatric disorder in the medical service in Taiwan is unknown. Using the claims data of a nationally representative cohort from the Taiwan National Health Insurance Research Database, the diagnoses of psychiatric disorders among newly diagnosed HIV-infected individuals were investigated from 1998 through 2006. Two hundred and seventy-four (23.8%) of 1153 newly diagnosed HIV-infected patients were identified as having psychiatric disorders, with an average latency of 3.33±2.47 years after HIV infection. Anxiety and depressive disorders were the leading diagnoses. Male patients had lower morbidity (21.0% vs. 25.3%, p=0.056), but a shorter latency to be identified with a psychiatric disorder (2.1±2.13 vs. 3.9±2.40 years, p0.001) than females. This first population-based cohort study showed a high morbidity of psychiatric disorders among HIV-infected individuals, but with a long latency after infection, and a gender effect was noted. Regular psychiatric evaluation and follow-up and prompt intervention are necessary for HIV-infected individuals.

Objectives Tardive dyskinesia (TD) is generally considered the most severe extrapyramidal sequelae of antipsychotic treatments. Method Case report. Results We present a 20-year-old woman with previous treatment of risperidone 6–7 mg daily for approximately 4 years. She developed TD 2 years later after switching to paliperidone 9 mg daily. To the best of our knowledge, she is the first case report of having direct paliperidone-induced TD. Immediate treatments including paliperidone dose reduction to 6 mg daily, clonazepam 1.5 mg daily and trihexyphenidyl 2 mg daily were performed for 1 month, and her symptoms were relieved eventually after switching to clozapine 75 mg daily. Conclusion Although second-generation antipsychotics such as paliperidone are considered to have a lowered risk of developing TD, this case could bring awareness to clinicians of the possibility of TD with the use of any antipsychotics.
