Thoracoabdominal computed tomography neoplasia detection in patients with paraneoplastic pemphigus: the importance of collaboration between specialists.

INTRODUCTION: Paraneoplastic pemphigus (PNP) is an autoimmune disorder that is almost always linked to an underlying neoplasia. General radiologists are usually not aware of what kind of neoplasia can be associated with PNP. Therefore, this study evaluates the effect of a dermatology lecture on radiologists' neoplasia diagnosis performance. METHODS: Two radiologists evaluated thoracoabdominal computed tomography (CT) examination images of 43 patients with PNP in separate reading sessions blinded to each other's assessments. Six months after the first CT image evaluation session, the two radiologists attended a lecture by two dermatologists about PNP, and 6 months later the two radiologists assessed the same CT examinations again. RESULTS: Statistical analysis showed statistically significant differences in CT sensitivity between the first and the second round of image evaluation for both radiologists (reader 1: p = 0.0313; reader 2: p = 0.0156). CONCLUSIONS: This is the first study to evaluate the effectiveness of a dermatology lecture on diagnostic performance. It is very important for radiologists to be familiar with the particular neoplasms that can be associated with PNP because this can have a direct clinical impact on diagnostic performance.

Low diffusion level within a fibroadenoma as the sole sign of ductal carcinoma in situ: A case report.

We present a case of ductal carcinoma in situ within a fibroadenoma. Breast cancer arising within fibroadenoma incidence ranges from 0.125% to 0.02%, and ductal carcinoma in situ is not the most frequent malignancy that can be found within a fibroadenoma. Dynamic contrast-enhanced magnetic resonance imaging showed an oval mass with circumscribed margins and dark internal septations, suspicious for fibroadenoma. According to European Society of Breast Radiology diffusion-weighted imaging consensus, mean apparent diffusion coefficient value obtained by drawing a small region of interest on the lesion apparent diffusion coefficient map showed a low diffusion level. Therefore, ductal carcinoma in situ within a fibroadenoma was diagnosed at final pathology after surgical excision.

Alexithymia, Suicide Ideation and Homocysteine Levels in Drug Naïve Patients with Major Depression: A Study in the "Real World" Clinical Practice

Objective: : This study was performed to elucidate relationships between alexithymia, suicide ideation and homocysteine levels in drug-naïve outpatients with major depressive disorder (MDD). Methods: : Sixty seven outpatients with MDD with melancholic features were evaluated by the means of the Hamilton Depression Rating Scale, the Toronto Alexithymia Scale (TAS-20), the Scale of Suicide Ideation, and homocysteine levels. Results: : Alexithymic subjects showed higher scores on all scales and higher homocysteine levels. Regression analysis shown higher homocysteine levels and TAS-20' "Difficulty in Describing Feelings" dimension, in turn being associated with higher suicide ideation. Conclusion: : In conclusion, alexithymic MDD outpatients may characterize for homocysteine dysregulation that may be linked to suicide ideation, regardless depression' severity. However, study limitations are discussed and must be considered.

Agomelatine Increases BDNF Serum Levels in Depressed Patients in Correlation with the Improvement of Depressive Symptoms.

BACKGROUND: Agomelatine modulates brain-derived neurotrophic factor expression via its interaction with melatonergic and serotonergic receptors and has shown promising results in terms of brain-derived neurotrophic factor increase in animal models. METHODS: Twenty-seven patients were started on agomelatine (25mg/d). Venous blood was collected and brain-derived neurotrophic factor serum levels were measured at baseline and after 2 and 8 weeks along with a clinical assessment, including Hamilton Depression Rating Scale and Snaith-Hamilton Pleasure Scale. RESULTS: Brain-derived neurotrophic factor serum concentration increased after agomelatine treatment. Responders showed a significant increase in brain-derived neurotrophic factor levels after 2 weeks of agomelatine treatment; no difference was observed in nonresponders. Linear regression analysis showed that more prominent brain-derived neurotrophic factor level variation was associated with lower baseline BDNF levels and greater anhedonic features at baseline. CONCLUSIONS: Patients affected by depressive disorders showed an increase of brain-derived neurotrophic factor serum concentration after a 2-week treatment with agomelatine. The increase of brain-derived neurotrophic factor levels was found to be greater in patients with lower brain-derived neurotrophic factor levels and marked anhedonia at baseline.
