RESUMO
Background: Vismodegib is indicated for the treatment of advanced or metastatic basal cell carcinoma (BCC). The predictive factors of response to vismodegib have so far been poorly described. Objectives: The primary objective was to determine the profile of patients responding to vismodegib and the duration of response. Secondary objectives were to assess whether there is a correlation between the duration of treatment and the risk of relapse, and to define factors associated with relapse. Materials & Methods: We included 61 patients with locally advanced BCC (laBCC) or multiple BCC, treated with vismodegib (150 mg per day), from July 2011 to November 2015, in the Oncodermatology Department of Nantes University Hospital in France. Tumour response was assessed using Response Evaluation Criteria in Solid Tumours version 1.1. Results: Thirty-nine patients had advanced BCC (64%) and 22 patients multiple BCC (36%), including 10 patients with Gorlin syndrome. No factor predicted response to vismodegib. The median progression-free survival (PFS) was 69.5 months for the total population. In multivariate analysis, multiple BCC was the only factor associated with an increased risk of relapse (HR: 13.80 [CI95%, 1.93-98.64, p < 0.01]). Treatment duration decreased the risk of relapse (HR 0.95 [CI95%, 0.90-0.99, p = 0.0467]). Among the 20 patients who experienced relapse during follow-up, 15 (75%) were re-treated with vismodegib, with a response rate of 66%. Conclusion: Although we were unable to establish predictive factors for the response to vismodegib, we demonstrate for the first time that increased treatment duration correlates with a decreased risk of relapse.

No recent study has focused on clinical features of subclinical hypothyroidism (SCH), especially in older patients. TSH measurement has remarkably evolved these last 20 years and thus reconsideration is needed. In our prospective multicenter study (2012-2014) including 807 subjects aged <60 years (<60y) and 531 subjects ≥60 years (≥60y), we have monitored 11 hypothyroidism-related clinical signs (hCS) together with TSH, FT4, FT3 and anti-thyroperoxidase antibodies values. hCS expression has been compared in patients with SCH vs euthyroidism in each age group. The number of hCS above 60y of age were found to be more elevated in the euthyroid population (1.9 vs 1.6, p<0.01) than in the SCH population (2.3 vs 2.6, p=0.41) while increase in hCS is limited to SCH subjects in the <60y group (p<0.01). The percentage of subjects with at least 3 signs increased with SCH in the <60y group (42.6% vs 25.0%, p<0.01) but not ≥60y (34.4% vs 33.9%, p=0.96). In older individuals, only three hCS could be related to both SCH and a decreased T3/T4-ratio (0.26 vs 0.27, p<0.01), suggesting either a reduced activity of TSH, or an adaptive response with aging. While hCS are clearly associated with SCH in patients <60y, they are not so informative in older subjects. TSH measurements carried out on the basis of hCS need to be interpreted with caution in aged patients. A reassessment of the TSH reference range in older patients is clearly needed and should be associated to more appropriate monitoring of thyroid dysfunction.
RESUMO
The prevalence of acne in the adult population is increasing, particularly in women. Spironolactone regulates sebaceous gland activity by blocking androgen receptor. To evaluate retrospectively the efficacy of spironolactone in women with acne. Data from 70 women of at least 20 years, treated for their acne between 2010 and 2015 with low-dose spironolactone (≤150 mg/day), were analysed. Remission was defined by the number of retentional lesions inferior or equal to five and inflammatory lesions inferior or equal to two on the face. Variables influencing the response were studied using the Cox model. The mean age was 31.3 years; 39 (56%) women had prior courses of isotretinoin and 53 (76%) had an oral contraception prior to treatment. Remission data from a median treatment period of six months (95% CI: 4-9) were obtained from 47 (71%) women. Markers for a positive response to spironolactone were a high number of inflammatory lesions at inclusion (OR: 1.08; 95% CI: 1.03-1.13; p = 0.001) and relapse with previous isotretinoin (OR: 2.46; 95% CI: 1.09-5.54; p = 0.03). The marker for a negative response was an association with oral contraceptives containing first or second-generation progestin (OR: 2.77; 95% CI: 1.35-5.71; p = 0.005). This retrospective data analysis confirms that the use of low doses of spironolactone is a valuable alternative in women with acne in whom oral isotretinoin has failed. Moreover, the analysis shows that first and second-generation oral contraceptives decrease the efficacy of spironolactone, confirming the interest of using two third or fourth-generation oral contraceptives.

BACKGROUND: Administrative bodies for compensating medical accidents were created in France in 2002. OBJECTIVES: To evaluate the knowledge patients with severe cutaneous adverse reactions (SCARs) have of procedures and to compare the rate of compensation for SCARs for France and for our referral center. METHODS: A questionnaire was sent to 247 patients of our SCARs referral center and 225 patients with Stevens-Johnson syndrome and toxic epidermal necrolysis from the patient association AMALYSTE. We calculated the rate of compensation for France and our center. RESULTS: Among the 123 respondents (26%), 28 (23%) knew the compensation procedure; 13 (11%) had received compensation. The Commission of Conciliation and Compensation had received 63 applications for SCARs since 2002 and proposed compensation for 56%. The estimated rate of compensation for France was 2.6% and 2.5% for our referral center (p = 0.9). CONCLUSIONS: The procedure of compensation for SCARs is misunderstood. Better information should be disseminated for patients with threshold disability conditions.

Attention-deficit/hyperactivity disorder (ADHD) is associated with deficits in spatial and sustained attention processes normally linked to the right parietal and frontal lobes. However, data on lateralization changes in attention processes are sparse. Little research has addressed whether the problems may reflect a more widespread lateralization disorder or whether there are lateralization changes over time. To address these issues, the authors examined several tasks, each using a lateralized process largely localized to a particular lobe and 2 age ranges (11-14 and 18-26 years) of unmedicated ADHD participants and control participants. ADHD children bisected lines significantly more rightward compared with control children, indicating an altered spatial attention process normally localized to the right parietal lobe. This problem was absent in young adults, suggesting a developmental resolution. The authors observed sustained attention decrements at both ages appearing earlier in the left hemisphere during a vigil. Finally, in these preliminary data, ADHD-related problems appeared specific to attention processes.

This preliminary study explored the prevalence of spirituality in family resilience in the adaptation process after the loss of a parent. Twenty-five families who lost a parent between one and six years previously were identified by four postgraduate students in their respective neighborhoods in Cape Town, South Africa. Each of the single parents (M age=48.3 yr., SD=7.7), 19 women and six men, were asked to indicate verbally in what way spirituality or religion had contributed to family adaptation after the death of the spouse. The semistructured interviews supplied evidence that a relationship between spirituality and family resilience does indeed exist.
