Facial and bodily emotion recognition in multiple sclerosis: the role of alexithymia and other characteristics of the disease.

Multiple sclerosis (MS) may be associated with impaired perception of facial emotions. However, emotion recognition mediated by bodily postures has never been examined in these patients. Moreover, several studies have suggested a relation between emotion recognition impairments and alexithymia. This is in line with the idea that the ability to recognize emotions requires the individuals to be able to understand their own emotions. Despite a deficit in emotion recognition has been observed in MS patients, the association between impaired emotion recognition and alexithymia has received little attention. The aim of this study was, first, to investigate MS patient's abilities to recognize emotions mediated by both facial and bodily expressions and, second, to examine whether any observed deficits in emotions recognition could be explained by the presence of alexithymia. Thirty patients with MS and 30 healthy matched controls performed experimental tasks assessing emotion discrimination and recognition of facial expressions and bodily postures. Moreover, they completed questionnaires evaluating alexithymia, depression, and fatigue. First, facial emotion recognition and, to a lesser extent, bodily emotion recognition can be impaired in MS patients. In particular, patients with higher disability showed an impairment in emotion recognition compared with patients with lower disability and controls. Second, their deficit in emotion recognition was not predicted by alexithymia. Instead, the disease's characteristics and the performance on some cognitive tasks significantly correlated with emotion recognition. Impaired facial emotion recognition is a cognitive signature of MS that is not dependent on alexithymia.

Accuracy of the spot sign on computed tomography angiography as a predictor of haematoma enlargement after acute spontaneous intracerebral haemorrhage: a systematic review.

BACKGROUND: A common early complication of intracerebral haemorrhage (ICH) is haematoma enlargement (HE), a strong independent predictor of a poor outcome. Therapeutic options to limit haematoma progression are currently scarce. Haemostatic therapy may be effective in patients with ICH, but it carries the risk of thromboembolic events in unselected patients. Accurate patient selection would, therefore, be of key importance for delivering potentially successful therapeutic strategies. Currently, there is no gold standard to accurately predict HE. The presence of contrast extravasation within the haematoma on computed tomography angiography (CTA), the 'spot sign', has been reported in several studies and seems a particularly promising marker but lacks a standardised evaluation so far. SUMMARY: We conducted a systematic review of published data to address the research question: In adults with acute spontaneous ICH, how accurately does the spot sign predict HE on follow-up imaging and thus poor functional outcome or mortality? We searched PubMed and Embase databases (from 1980 to May 2012), using a highly sensitive search strategy and including all studies involving adult patients with spontaneous ICH evaluated with CTA and follow-up CT scans, reporting any measure of clinical outcome, and reporting or allowing calculation of accuracy measures of the spot sign in predicting HE and clinical outcome. Baseline characteristics, accuracy measures and effect measures, as well as bias assessment, were reported according to PRISMA recommendations. The quality of the studies was appraised using an adapted version of the REMARK reporting recommendations. From 259 potentially relevant studies, we finally selected 6 studies (1 of them was a multicentre cohort study) covering a total of 709 patients. Studies varied substantially in terms of size, methodological quality, definitions of terms, outcomes selected and results. In particular, definition of the spot sign was not consistent in all studies. Furthermore, the only outcome measure consistently available was HE, while definitions and analyses of clinical outcomes seemed not adequate. Lastly, the choice of candidate variables for univariate and multivariate analyses did not include all determinants of HE and poor functional outcome. High heterogeneity was demonstrated (I(2): 94% for HE) with substantial potential of bias. KEY MESSAGES: Studies of the spot sign are diverse and therefore complex to interpret. Our research question could not be answered due to heterogeneity and potential of bias in the selected studies. Further appropriately powered studies using standardised definitions and taking all predictors of HE and poor clinical outcome into account are required for a proper clinical implementation.

The incidence of amyotrophic lateral sclerosis in Friuli Venezia Giulia, Italy, from 2002 to 2009: a retrospective population-based study.

BACKGROUND: We conducted a retrospective population-based study to estimate the incidence of amyotrophic lateral sclerosis (ALS) in Friuli Venezia Giulia, Italy, from 2001 to 2009. METHODS: Multiple sources were used for case ascertainment: Health databases, archives of the neurology departments and of the regional chapter of the Italian ALS Association. The diagnosis was validated through clinical documentation review. Crude and standardized incidence rates (IRs) per 100,000 person-years were calculated. RESULTS: We identified 262 incident ALS cases, 50.4% men, 4.2% familial. Half of the patients had spinal onset (56.8% in men) and 25.2% bulbar (29% in women). Bulbar onset had a similar frequency in women (31.7%) and men (31.5%) aged 67 or above at diagnosis. The crude IR was 2.72 (95% confidence interval, 95% CI, 2.39-3.05) and the male:female ratio 1.08. The IR peaked in the 65-74 age group, with a second increase in men 85 years and older. The IR standardized to the 2001 Italian population was 2.38 (95% CI 2.13-2.63) and to the 2000 European population 2.58 (95% CI 2.34-2.81). CONCLUSIONS: This retrospective study found IRs of ALS in the range of Italian and European prospective population-based registries, suggesting an almost complete case ascertainment.

Tobacco withdrawal in women and menstrual cycle phase.

Because negative mood is a characteristic of both tobacco withdrawal and menstrual discomfort, withdrawal may vary by menstrual cycle phase. Tobacco withdrawal, mood, and menstrual discomfort were assessed in premenopausal women who quit smoking during either the follicular (Days 1-14 postmenstrual onset; n = 41) or luteal (Day 15 or longer postmenstrual onset; n = 37) phase of the menstrual cycle and maintained biochemically verified smoking abstinence during the postquit week. Women quitting during the luteal phase reported significantly greater increases in tobacco withdrawal and self-reported depressive symptoms than women quitting during the follicular phase. These results indicate that selecting a quit-smoking day early in the follicular phase may attenuate withdrawal and negative affect in premenopausal female smokers.
