Vitamin D: An Overlooked Parameter in Studies of Depression Using Optic Coherence Tomography.

Introduction: The relationship between depression and inflammation and the resulting vascular/neuronal damage have been demonstrated in recent studies. In this study we aimed to investigate inflammation and the possible degeneration that can be caused by depression and accompanying vitamin D deficiency using a non-invasive imaging method of optical coherence tomography (OCT). Methods: Twenty-four healthy controls and 42 drug free major depressive patients matched for age, sex and eye measurements were compared in terms of vitamin D, C Reactive Protein (CRP) and OCT parameters. The Hamilton Depression Rating Scale (HAM-D), The Clinical Global Impressions Scale (CGI) and Global Assessment of Functioning Scale (GAF) were used to assess disease severity. Results: CRP level and choroidal thickness in the major depression group were significantly higher than the healthy controls. Vitamin D level and the ganglion cell layer (GCL) volume was significantly lower in the major depression group compared to healthy controls. Positive correlation was found between HAM-D and CRP in major depressive patients; a negative correlation was found between current attack duration and GCL volume. CGI was positively correlated with CRP and HAM-D. GAS was negatively correlated with CRP and HAM-D. Conclusion: It has been shown that major depression might be an inflammatory disorder with possible degenerative processes observed with OCT and CRP measurements. But longitudinal follow up studies are needed to demonstrate a cause and effect relationship.

Temperament and Character Profiles of Ankylosing Spondylitis Patients Compared With Major Depression Patients and Healthy Controls.

BACKGROUND/OBJECTIVE: Depressive disorder is common in patients with ankylosing spondylitis (AS), who exhibit specific brain imaging abnormalities resembling those in major depression (MD). We compared temperament and character profiles between patients with AS and MD. METHODS: The study involved 36 patients with AS, 40 with MD, and 36 healthy controls (HCs). The participants were age-, sex-, and education-matched. Depression, anxiety, temperament, and character were evaluated using the Temperament and Character Inventory and physician-rated Hamilton Depression and Anxiety Scales. Disease severity was assessed using the Bath Ankylosing Spondylitis Disease Activity, Radiology, Metrology, and Functionality Indexes; erythrocyte sedimentation rate; and C-reactive protein. RESULTS: Depression and anxiety scores were highest in MD, lowest in HCs, and intermediate in AS (p < 0.001). Harm avoidance was significantly higher in MD and AS than HCs (p = 0.01). Reward dependency was lower (p = 0.011) and self-transcendence higher in AS only (p = 0.034). Bath Ankylosing Spondylitis Radiology Index was negatively correlated with depression (p = 0.020). Bath Ankylosing Spondylitis Radiology Index and Bath Ankylosing Spondylitis Metrology Index were negatively correlated with harm avoidance (p < 0.05). Disease duration was negatively correlated with self-transcendence (p = 0.027). Harm avoidance was correlated with depression score (p = 0.029). Patients under tumor necrosis factor α inhibitor treatment had lower cooperativeness score (p = 0.022). CONCLUSIONS: Patients with AS had a specific Temperament and Character Inventory pattern. Harm avoidance was common in both AS and MD. In AS, harm avoidance and depression decreased in patients with progression, probably because progressive fusion of the spinal segments causes decrease in pain. Harm avoidance (fear of pain) seemed to be an acting factor for occurrence of depressive symptoms in AS.

Stress and psychopathology and its impact on quality of life in chronic anal fissure (CAF) patients.

BACKGROUND: Chronic anal fissure (CAF) onset, exacerbation, and impact on quality of life are influenced by a host of psychological, physiological, and social factors. We aimed to investigate the difference in psychopathology and stress between normal and CAF groups. METHODS: Thirty CAF patients and 20 age-sex matched healthy controls were evaluated for Axis I psychopathology, depression, anxiety, and stress with Hamilton and Hospital Depression-Anxiety Scales, Perceived Stress Scale, and SF-36. RESULTS: With a mean age of 39.47, 83.3% of CAF patients were female. Anxiety-depression and stress scores were all significantly higher and functionality was lower in the CAF group compared to controls (p < 0.001); 36.7% of the patients had a triggering stress factor and 56.6% had an exacerbating stress factor; 56.7% of the patients had an ongoing Axis I psychopathology while 50% had a previous psychopathology. Pain (96.7% had pain (VAS = 6.55)) and bleeding (83.3% had bleeding (VAS = 4.14)) severity showed a negative impact on bodily pain and role limitations emotional subscales of SF36. CONCLUSION: There is a high comorbidity of psychopathology in the CAF patients and depression and anxiety severities show a negative impact on the quality of life. Stress acts as both a triggering and an exacerbating factor in CAF.

The comorbidity of reduplicative paramnesia, intermetamorphosis, reverse-intermetamorphosis, misidentification of reflection, and capgras syndrome in an adolescent patient.

Delusional misidentification syndromes may be superimposed on neurological or psychiatric disorders and include delusional beliefs that the people, objects, or places around the patient change or are made to change with one another. In this paper, an adolescent patient displaying Capgras syndrome, metamorphosis, reverse-intermetamorphosis, misidentification of reflection, and reduplicative paramnesia was presented. The findings that our patient struggled with visuospatial tests applied in the acute phase as well as the observation that she refused to meet her family face-to-face while accepting to speak on the phone may support the role of right hemisphere and visuospatial functions in the development of those syndromes. Further studies or case series evaluated more extensively are needed to reveal the relationship between right hemisphere functions and delusional misidentification syndromes.

The relationship of cognitive impairment with neurological and psychiatric variables in multiple sclerosis patients.

OBJECTIVE: Cognitive impairment (CI) in multiple sclerosis (MS) can develop any time. CI is associated with the degree of neuronal loss, but disease duration, fatigue, comorbid affective disorder, and drug dose may also affect cognition. Our aim was to assess which cognitive domain was disturbed primarily in mild MS patients and to see whether CI was related with clinical and psychiatric features. METHOD: Neurological and psychiatric evaluation of 31 MS patients and 31 age, sex, and education-matched healthy controls were made with Structured Clinical Interview for Axis I Disorders (SCID-I). Depression, anxiety, functionality, fatigue, and disability scoring were determined with Hamilton Depression-Anxiety scales, Global Assessment of Functionality, Fatigue Severity and Expanded Disability Status Scales. Cognitive functions were assessed using Mini Mental, Serial Digit Learning, Verbal and Nonverbal Cancellation, Stroop and Rey Auditory Verbal Learning tests. RESULTS: Retrieval from long-term memory and psychomotor speed were significantly worse in MS group. CI was correlated with disease duration, number of attacks, and physical disability but not with depression and anxiety severity. Disease duration predicted disturbances in recall and psychomotor speed, whereas fatigue and disability predicted depression. CONCLUSION: Psychomotor speed and memory were primarily impaired in MS patients, and CI was closely associated with clinical aspects of MS rather than with depression and anxiety.

Transcutaneous electrical posterior tibial nerve stimulation for chronic anal fissure: a preliminary study.

PURPOSE: Recent studies showed that sacral nerve stimulation might be an effective treatment option for chronic anal fissure. We aimed to evaluate the efficacy of transcutaneous electrical nerve stimulation as a noninvasive alternative treatment for chronic anal fissure by stimulating the sacral nerve in the ankle via the posterior tibial nerve. METHOD: In this prospective study, transcutaneous electrical nerve stimulation was applied for 10 days in addition to conventional medical treatment in ten patients. Wexner's constipation score, visual analog scale for pain, quality of life (Short Form-36), Hamilton anxiety and depression scores, symptom relief, compliance, fissure healing, and side effects were evaluated before and after treatment (days 0, 5, and 10). RESULTS: Ten patients (eight females/two males) with a mean age of 50.7 ± 18.5 years were enrolled in the study. Pain and bleeding resolved in all patients 2 days after the treatment, and mucosal healing was observed in six patients 10 days after the treatment. Wexner's constipation and visual analog scale scores for pain decreased significantly (p = 0.001 and p = 0.002, respectively). Hamilton anxiety and depression scores decreased as well (p = 0.001 and p = 0.01, respectively). Among Short Form-36 subscales, only mental health score increased significantly (p = 0.003). One patient underwent surgery at follow-up due to recurrence of symptoms, and rubber band ligation was applied to another patient who had internal hemorrhoidal rectal bleeding at the end of 10 days. CONCLUSIONS: Transcutaneous electrical nerve stimulation application to the posterior tibial nerve has the potential to be an alternative treatment option for chronic anal fissure patients who seek noninvasive treatment modality.

The effect of TNF-alpha blockers on psychometric measures in ankylosing spondylitis patients: a preliminary observation.

There is a high co-morbidity between chronic inflammatory disorders and depression. Proinflammatory cytokines like TNF-α seem to play a central role in the pathogenesis of these disorders, and its neutralization provides a potent treatment for inflammatory disorders. Few studies showed that TNF-α blockers also caused an improvement in depressive symptoms associated with these chronic inflammatory disorders. To evaluate the effectiveness of TNF-α blockers on symptoms of ankylosing spondylitis (AS), depression, anxiety and quality of life, 9 AS patients resistant to classical therapy were enrolled and followed-up at 2nd and 6th weeks after a TNF-α blocker was started. Hamilton Depression and Anxiety Scales (HAM-D, HAM-A), Hospital Depression and Anxiety Questionnaire (HAD), Quality of Life Scale (SF36) and AS severity index (BASDAI) were applied to the patients at weeks 0, 2 and 6. ESR and CRP were evaluated to monitor biological disease activity. There was a significant reduction in HAM-D (p = 0.00), HAM-A (p = 0.00), HAD anxiety scores (p = 0.02) and a significant improvement in SF36 physical function (p = 0.00), physical role limitations (p = 0.00), bodily pain (p = 0.05), general health (p = 0.01), vitality (p = 0.03) and emotional role limitations (p = 0.00) subscales, BASDAI scores (p = 0.00), ESR (p = 0.00) and CRP (p = 0.00). Change in clinical disease activity (BASDAI) was not correlated with change in depression-anxiety scores, while change in biological disease activity (CRP) was correlated with change in depression-anxiety scores. TNFα blockers may have a potential antidepressant effect besides its anti-inflammatory effect that seems to be independent of its clinical effect.

[Genetic studies of bipolar disorder: a review]. / Bipolar Bozuklukla Ilgili Genetik Arastirmalar: Bir Gözden Geçirme.

Bipolar disorder is a severe mental illness that afflicts approximately 1% of the world's population, and is characterized by mood swings from elation to depression. Although the etiology of bipolar disorder remains unclear, heritable factors have been shown to be involved. Family, twin, and adoption studies suggest a genetic etiology. Molecular genetic studies also support a genetic component. Many chromosomal regions have been implicated by these molecular genetic studies, but no single susceptibility gene has been identified. These findings show that bipolar disorder has a complex genetic etiology in which multiple unidentified genes and environmental factors play an important role in its pathogenesis. Herein, molecular genetic studies of bipolar disorder are reviewed based on a search of Medline using the key words, bipolar, genetic, and chromosome. Studies with positive results for bipolar disorder were selected first. The findings from these molecular genetic studies are reviewed systematically, chromosome by chromosome. Causes of the differences between the reported findings and of non-replication are discussed. Finally, important factors for designing a genetic study of bipolar disorder are examined.
