Thyroid Autoimmune Antibodies and Major Depressive Disorder in Women.

INTRODUCTION: Anti-thyroid antibodies are associated with extra-thyroid diseases such as Graves' ophthalmopathy and Hashimoto's encephalopathy. Some evidence suggests that anti-thyroid antibodies are also associated with depression. Interleukin (IL)-17 appears to play an important role in autoimmune thyroid disease. This study investigated whether specific thyroid autoantibodies and IL-17 distinguished persons with depression from non-depressed controls. MATERIALS AND METHODS: Forty-seven adult females with non-psychotic, current major depressive disorder and 80 healthy female controls participated in this study. Thyroid peroxidase antibodies, thyroglobulin antibodies, thyroid-stimulating hormone (TSH) receptor antibodies, free T3 and T4, TSH and IL-17 were measured from the serum. Measurements were repeated to assess test-retest reliability. Receiver operating characteristic (ROC) curves were used to estimate discriminatory values of the measurements. Differences between groups and associations between the clinical and biochemical assessments were analysed. RESULTS: Median TSH receptor antibody concentration was significantly higher in the depressed than control group (P <0.001). Area under the ROC curve was 0.80 (95% CI, 0.73 to 0.88). Higher TSH receptor antibody titres were associated with greater depression severity scores (r = 0.33, P <0.05). IL-17 levels were not associated with TSH receptor antibody levels or depression severity scores. Thyroid function and other thyroid autoantibodies were not associated with depression severity. CONCLUSION: TSH receptor antibodies might be a biomarker of immune dysfunction in depression.

Hoarding in Singapore.

Hoarding refers to an excessive acquisition of objects and inability to part with apparently valueless possessions. While it can lead to excessive clutter, distress and disability, it is important to note that not all cases of hoarding are pathological. This article aims to suggest how one can make recommendations to patients and families when they encounter someone exhibiting hoarding behaviour. It also introduces the Hoarding Task Force and relevant legislation in Singapore to address the issue of hoarding in the community.

Comprehensive psychological intervention to improve outcome in functional gastrointestinal disorder: a cohort study.

INTRODUCTION: Patients with functional gastrointestinal disorders (FGIDs) have a decreased quality of life (QoL). Psychological illnesses are strongly associated with FGIDs. This study examined the effect of a comprehensive psychological intervention programme designed for refractory FGID patients. METHODS: Refractory FGID patients at a tertiary gastroenterology unit were encouraged to participate in a psychological intervention programme, which included screening for anxiety and depression in patients, educating patients and physicians on FGIDs, and providing early access to psychiatric consultation for patients with significant psychological illnesses. The duration of follow-up was six months. Outcomes were measured using the Irritable Bowel Syndrome-QoL (IBS-QoL) instrument and the EuroQol five dimensions (EQ-5D) questionnaire. RESULTS: A total of 1,189 patients (68% female, 80% Chinese, mean age 48.6 years) participated in the programme. Among these participants, 51% had a significant psychological disorder (Hospital Anxiety and Depression Scale [HADS] anxiety or depression score > 7). These participants had a significantly poorer QoL (IBS-QoL and EQ-5D, both p < 0.0001), and were more likely to be single or English-speaking, as compared to the participants without psychological disorders. Participants who completed ≥ 3 months of follow-up (n = 906) showed significant and durable improvement. High baseline HADS anxiety score predicted improvement (p < 0.001), with participant IBS-QoL and EQ-5D scores decreasing over time. CONCLUSION: The intervention programme was associated with a clinically meaningful improvement in the QoL of patients with refractory FGIDs. High baseline anxiety was predictive of improvement.

Review of sleep studies of patients with chronic insomnia at a sleep disorder unit.

INTRODUCTION: Chronic insomnia is associated with many physical and psychiatric illnesses, and its underlying aetiology needs to be identified in order to achieve safe and effective treatment. Obstructive sleep apnoea (OSA) and periodic limb movement disorder (PLMD) are common primary sleep disorders that can lead to chronic insomnia. Patients with these conditions are evaluated using polysomnography (PSG). METHODS: The PSG records of 106 patients with chronic insomnia who presented to a multidisciplinary sleep clinic in Singapore over a five-year period were reviewed. To examine the utility of PSG in the evaluation of chronic insomnia, the clinical diagnoses of the patients before and after the sleep studies were compared. RESULTS: Among the 106 patients, 69 (65.4%) were suspected to have primary sleep disorders based on clinical history and examination alone. Following PSG evaluation, 42.5% and 4.7% of the study population were diagnosed with OSA and PLMD, respectively. OSA was found in 35.9% of the 39 patients who had underlying psychiatric conditions. CONCLUSION: This study illustrates that many patients with chronic insomnia have underlying primary sleep disorders. It also highlights the danger of attributing chronic insomnia in psychiatric patients to their illness, without giving due consideration to other possible aetiologies. Clinicians should maintain a high index of suspicion for the presence of other aetiologies, and make timely and targeted referrals for sleep studies where appropriate.

Application of low-cost methodologies for mobile phone app development.

BACKGROUND: The usage of mobile phones and mobile phone apps in the recent decade has indeed become more prevalent. Previous research has highlighted a method of using just the Internet browser and a text editor to create an app, but this does not eliminate the challenges faced by clinicians. More recently, two methodologies of app development have been shared, but there has not been any disclosures pertaining to the costs involved. In addition, limitations such as the distribution and dissemination of the apps have not been addressed. OBJECTIVE: The aims of this research article are to: (1) highlight a low-cost methodology that clinicians without technical knowledge could use to develop educational apps; (2) clarify the respective costs involved in the process of development; (3) illustrate how limitations pertaining to dissemination could be addressed; and (4) to report initial utilization data of the apps and to share initial users' self-rated perception of the apps. METHODS: In this study, we will present two techniques of how to create a mobile app using two of the well-established online mobile app building websites. The costs of development are specified and the methodology of dissemination of the apps will be shared. The application of the low-cost methodologies in the creation of the "Mastering Psychiatry" app for undergraduates and "Déjà vu" app for postgraduates will be discussed. A questionnaire survey has been administered to undergraduate students collating their perceptions towards the app. RESULTS: For the Mastering Psychiatry app, a cumulative total of 722 users have used the mobile app since inception, based on our analytics. For the Déjà vu app, there has been a cumulative total of 154 downloads since inception. The utilization data demonstrated the receptiveness towards these apps, and this is reinforced by the positive perceptions undergraduate students (n=185) had towards the low-cost self-developed apps. CONCLUSIONS: This is one of the few studies that have demonstrated the low-cost methodologies of app development; as well as student and trainee receptivity toward self-created Web-based mobile phone apps. The results obtained have demonstrated that these Web-based low-cost apps are applicable in the real life, and suggest that the methodologies shared in this research paper might be of benefit for other specialities and disciplines.

Future Role For Motivational Interviewing In The Treatment Of Insomnia - An Opinion

Objective: This paper aims to explore the possibility of using motivational interviewing (MI) as a therapy for insomnia patients. Methods: We reviewed the current practice guidelines for insomnia, and noted the issues pertaining to types of treatment, notably CBT-I. We also reviewed some studies which seem to suggest that MI treats insomnia. Results: MI is a proven technique for other psychiatric illnesses. There are currently not many studies done evaluating the efficacy of MI on insomnia. Of those published studies, they are either underpowered to draw any firm conclusions, or it is limited to a particular age group. Conclusion: There seems to be promise in the area of MI on insomnia. Given the paucity of data in this area, more research with bigger group of study participants are needed to fully conclude the effectiveness of this treatment.

Evidence-based guidelines on the use of opioids in chronic non-cancer pain--a consensus statement by the Pain Association of Singapore Task Force.

INTRODUCTION: While opioids are effective in carefully selected patients with chronic non-cancer pain (CNCP), they are associated with potential risks. Therefore, treatment recommendations for the safe and effective use of opioids in this patient population are needed. MATERIALS AND METHODS: A multidisciplinary expert panel was convened by the Pain Association of Singapore to develop practical evidence-based recommendations on the use of opioids in the management of CNCP in the local population. This article discusses specific recommendations for various common CNCP conditions. RESULTS: Available data demonstrate weak evidence for the long-term use of opioids. There is moderate evidence for the short-term benefit of opioids in certain CNCP conditions. Patients should be carefully screened and assessed prior to starting opioids. An opioid treatment agreement must be established, and urine drug testing may form part of this agreement. A trial duration of up to 2 months is necessary to determine efficacy, not only in terms of pain relief, but also to document improvement in function and quality of life. Regular reviews are essential with appropriate dose adjustments, if necessary, and routine assessment of analgesic efficacy, aberrant behaviour and adverse effects. The reasons for discontinuation of opioid therapy include side effects, lack of efficacy and aberrant drug behaviour. CONCLUSION: Due to insufficient evidence, the task force does not recommend the use of opioids as first-line treatment for various CNCP. They can be used as secondor third-line treatment, preferably as part of a multimodal approach. Additional studies conducted over extended periods are required.

Qualities of a psychiatric mentor: a quantitative Singaporean survey.

OBJECTIVE: Psychiatric mentors are an important part of the new, seamless training program in Singapore. There is a need to assess the qualities of a good psychiatric mentor vis-à-vis those of a good psychiatrist. METHOD: An anonymous survey was sent out to all psychiatry trainees and psychiatrists in Singapore to assess quantitatively the relative importance of 40 qualities for a good psychiatrist and a good mentor. RESULTS: The response rate was 48.7% (74/152). Factor analysis showed four themes among the qualities assessed (professional, personal values, relationship, academic-executive). A good mentor is defined by professional, relationship, and personal-values qualities. Mentors have significantly higher scores than psychiatrists for two themes (relationship and academic-executive). CONCLUSION: Being a good mentor, in Asia, means being a good psychiatrist first and foremost but also requires additional relationship and academic-executive skills. Mentors should be formally trained in these additional skills that were not part of the psychiatric curriculum.

Electroconvulsive therapy for catatonia in neuropsychiatric systemic lupus erythematosus.

Neuropsychiatric systemic lupus erythematosus encompasses neurological syndromes of the central, peripheral, and autonomic nervous system and a variety of psychiatric syndromes. Neuropsychiatric systemic lupus erythematosus presenting as catatonia is uncommon, and treatment of this condition is not well defined. Here we describe a case of neuropsychiatric systemic lupus erythematosus with catatonia and our treatment approach focusing on electroconvulsive therapy in conjunction with cyclophosphamide. We also discuss the pathophysiological underpinnings of the condition and the basis for treatment.

Efficacy of cognitive behavioural therapy for patients with chronic pain in Singapore.

BACKGROUND: The use of Cognitive Behavioural Therapy (CBT) techniques to manage chronic pain is relatively new and understudied in Singapore. Using data collected from group CBT programmes carried out at the Singapore General Hospital (SGH), we seek to explore the efficacy of the programme on pain intensity, self-efficacy, attitudes towards pain, and emotional factors. We also examined the efficacy of the longer 6- to 9-day group programme versus an abridged 2-day version called the Pacing Programme covering only some aspects of the full group programme. MATERIALS AND METHODS: Twenty-nine adult patients underwent the intensive 6- to 9-day group programme while another 10 patients underwent the abridged 2-day group programme. The more extensive group programme encompassed teaching patients cognitive-behavioural methods of coping with pain, such as setting goals, pacing, cognitive restructuring by thinking in more positively, distraction, problem solving, sleep hygiene, communication skills, ability to cope with changes, and relaxation techniques. The abridged programme focused mainly on developing pacing skills. Patients were required to fill out questionnaires at the beginning of the programme, end of the programme, and at the 1-month and 6-month follow-ups to monitor progress. RESULTS: Preliminary results for the intensive 6- to 9-day group programme indicate decrease in pain and pain distress levels, improvements in management of pain, increased confidence to carry out activities despite pain, increased positive self-statements and decreased negative self-statements, decrease in fear of harm and pathophysiological beliefs, as well as decreases in the levels of depression, anxiety, and stress. The abridged 2-day programme yielded little change in pain and pain distress levels, but a slight increase in confidence to carry out activities despite pain. CONCLUSION: These preliminary results provide some evidence supporting the efficacy of CBT techniques in chronic pain management and contribute to the growing body of evidence for the effectiveness of psychological and behavioural techniques in the management of chronic pain.

Clinical aspects and management of fibromyalgia syndrome.

Fibromyalgia syndrome (FMS) is a chronic and debilitating musculoskeletal pain disorder of unknown aetiology with usual accompanying features of fatigue, sleep disturbances and stiffness. Its place in medical textbooks was controversial with rheumatologists holding the helm of its management for many years. Over the last decade, abnormalities have been identified at multiple levels in the peripheral, central, and sympathetic nervous systems as well as the hypothalomo-pituitary-adrenal axis stress response system. With the elucidation of these pathways of pain, FMS is known more as a central sensitivity syndrome. This led to tremendous increment in interest in both pharmacological and non-pharmacological treatment of FMS. The United States Food and Drug Administration (FDA) has also successively approved 3 drugs for the management of fibromyalgia--pregabalin, duloxetine and milnacipran. Non-pharmacological modalities showed aerobic exercise, patient education and cognitive behavioural therapy to be most effective. Overall, management of FMS requires a multi-disciplinary approach.

Use of antidepressants in the treatment of chronic pain.

There is a high prevalence of chronic pain disorders in the population and the individual and societal costs are large. Antidepressants have been used in the treatment of chronic pain and the pain-relieving effects are independent of the mood-elevating properties. We reviewed randomised-controlled trials, systematic reviews and meta-analyses of antidepressants in the treatment of chronic pain disorders which were identified through searches of MEDLINE and EMBASE. Antidepressants have proved to be effective in the treatment of fibromyalgia, chronic low back pain, diabetic neuropathy, postherpetic neuralgia and chronic headache, in particular tricyclic antidepressants (TCAs). There is emerging evidence that newer dual-action antidepressants are equally efficacious. Antidepressants provide a viable option in the management of chronic pain disorders. Further research into novel antidepressants will aid the pain clinician in optimising treatment for patients.

The media and suicide.

Suicide is a common and preventable event that is often reported by the media when there are sensationalistic elements or if the suicide involves a celebrity. Media reports of suicide can induce a copycat or "Werther effect". There is increasing evidence that sensationalistic reporting of suicides has a direct effect on increasing suicide rates. Responsible reporting guidelines drawn up in consultation with media professionals have been shown to improve reporting of suicides. Local reporting on suicides tends to be sensationalistic but also has a strong educational slant. The media should educate both the public and the medical professional about their role in suicide prevention.

Hypnotherapy for sleep disorders.

Hypnosis can be defined as a procedure during which changes in sensations, perceptions, thoughts, feelings or behaviour are suggested. Hypnosis can be used to amplify whatever it is about therapy that makes it therapeutic. It permits a wide range of choices regarding where and how to intervene in the patient's problems. In this paper, we set out to examine the rationale of using hypnotherapy to manage various types of sleep disorders, and to explore the techniques, strategies and hypnotic scripts employed by various hypnotherapists. We also examine the research data available on the efficacy of hypnosis in the treatment of sleep disorders. Acute and chronic insomnia often respond to relaxation and hypnotherapy approaches, along with sleep hygiene instructions. Hypnotherapy has also helped with nightmares and sleep terrors. There are several reports of successful use of hypnotherapy for parasomnias, specifically for head and body rocking, bedwetting and sleepwalking. Hypnosis is a specialised technique, not a therapy itself, and should be used as an adjunctive intervention within a complete psychological and medical treatment package. Most of the literature is limited to case reports or studies with such a small sample that at times it is very difficult to interpret the results. There is a major placebo effect, so uncontrolled trials are of limited value. It is hard to perform a randomised, double-blind, controlled trial to evaluate hypnotherapy given that cooperation and rapport between patient and therapist is needed to achieve a receptive trance state.
