The mutations identified in one or more of the four HCN channel subunits are found to be contributing to different epileptic phenotypes. S126L, S632W, V246M and E515K are four different mutations affecting the HCN2 subunit and have been reported in febrile seizures and partial/generalised idiopathic epilepsies.

We examined illness perceptions using the Revised Illness Perceptions Questionnaire in 55 patients with chronic hepatitis C virus infection, due to receive interferon-alpha. The Hospital Anxiety and Depression Scale was used to assess the development of symptoms.

This study aimed to assess iron deposition qualitatively and quantitatively by using SWI and microstructural changes in the corticospinal tract by using DTI in patients with amyotrophic lateral sclerosis.
Materials And Methods: Seventeen patients with amyotrophic lateral sclerosis and 15 age- and sex-matched controls underwent brain MR imaging with SWI and DTI.
Context: With the advent of new imaging modalities, radiologists are faced with handling increasing volumes of data for diagnosis and treatment planning. The use of automated and intelligent systems is becoming essential in such a scenario. Machine learning, a branch of artificial intelligence, is increasingly being used in medical image analysis applications such as image segmentation, registration and computer-aided diagnosis and detection.

Methods: A toxicology database was used to identify patients presenting with a history suggestive of withdrawal from GHB and analogues. Electronic and paper medical records were searched for demographic features, neuropsychiatric symptoms, psychiatric management while in hospital and overall outcome.
Background: Hepatitis C virus (HCV) affects 170 million worldwide. Currently, around 30% of patients receiving interferon-alpha (IFN-α) treatment for HCV experience clinically significant depression. Effective and timely detection of depression is crucial to ensuring appropriate treatment and support.

Methods: Semistructured face-to-face interviews with consultants and senior nurses were taped, transcribed and analyzed manually using the framework method of analysis.
Results: Twenty-five referrers were interviewed.
There is a tradition of using films to teach various aspects of psychiatry and we feel that Malayalam cinema can also be used suitably to teach effectively. These films can be an invaluable resource in cultural competency training as they depict the effects of culture on psychopathology and cultural and regional influences on attitudes to mental illness and stigma. We also note that the portrayal is often far from reality but this is not a barrier for using the films as an effective alternative to traditional and didactic teaching methods.

View Article and Find Full Text PDFDepression and fatigue are frequent side effects of interferon-alpha (IFN-alpha) treatment, and there is compelling evidence that the inflammatory response system (including interleukin-6, IL-6) and the serotonergic system is important in the pathophysiology of such symptoms. Functional polymorphisms in the promoter region of the IL-6 gene (rs1800795) and serotonin transporter gene (5-HTTLPR) have been identified as regulating these systems. The present study aimed to determine if these polymorphisms were associated with the development of depression and fatigue during IFN-alpha and ribavirin treatment.
View Article and Find Full Text PDFAs emotional distress is often seen as an understandable reaction to a severe or life-threatening illness, clinicians are reluctant to make a diagnosis of depression and resort to alternative diagnoses such as adjustment disorder (AD) or demoralisation. This paper introduces these concepts and critically examines their clinical utility. It concludes that neither AD nor demoralisation can be clearly distinguished from depression on variables such as clinical symptoms, outcome or treatment response.

Dhat syndrome is a widely recognized condition from the Indian subcontinent with fatigue and preoccupation with semen loss as the main presenting symptoms. This condition has been considered to be a culture-bound syndrome, but little is known about its illness characteristics and similarities with other conditions with medically unexplained symptoms. In this paper we review the current research on dhat syndrome, discuss its similarities and differences with other functional somatic syndromes, and propose an integrated model that incorporates both psychological and sociocultural factors.

Objective: To study the illness characteristics of Dhat syndrome, which has been widely regarded as a culture-bound syndrome.
Methods: The sample was selected from a general hospital and included 29 patients with Dhat syndrome and 32 medical controls. Somatization Screening Index (SSI), Illness Behaviour Questionnaire (SIBQ), Somatosensory Amplification Scale (SAS), Whitley Index (WI) and Chalder Fatigue Scale were administered to both groups.
Background: Chronic fatigue syndrome (CFS) is a controversial disorder with different case definitions, aetiological models and proposed treatments. An epidemiological approach is likely to bring some clarity to the field.
Aim: The aim of this article is to review the literature on the epidemiology of fatigue, chronic fatigue and CFS.
Background: The Social Adaptation Self-Evaluation Scale (SASS) is an instrument for measuring drive-based aspects of social functioning and has been used in trials of antidepressants. It has been suggested that social adaptation may be akin to a personality trait. We investigated the personality dimensions of neuroticism and extraversion as determinants of social functioning measured by SASS in patients with depression.
