Fibromyalgia is a syndrome characterized by chronic pain related to the musculoskeletal system. Patients feel incapable and show catastrophic thoughts (exaggeration of the sensations) related to painful events. This study aimed to compare catastrophic thoughts of pain between daughters of women with fibromyalgia and daughters of women without fibromyalgia, no daughter having the syndrome. It was a case-control study in which 76 women were included: 38 daughters of women diagnosed with fibromyalgia (case group), and 38 daughters of women without fibromyalgia (control group). The Brazilian versions of the Profile of Chronic Pain: Screen, the Pittsburgh Sleep Quality Index, the Pain Catastrophizing Scale, Resilience Scale, Beck Depression Inventory-II, and the State-Trait Anxiety Inventory were used. Data were tabulated and analyzed using SPSS 20.0. Continuous variables were compared between the groups using the Mann-Whitney U test or Student\'s t-test for independent samples. A significant difference was considered at p < 0.05. Regarding catastrophism, the case group had higher total catastrophism compared to the control group (p = 0.025). Daughters of patients with fibromyalgia showed higher rumination and magnification levels related to pain (p = 0.028 and p = 0.007, respectively) but did not show hopelessness. This study concludes that daughters of women with fibromyalgia are more likely to have symptoms of fibromyalgia due to their visualization of the syndrome. This indicates that emotional aspects may induce changes, and additional research on an individual basis is necessary.

Recent studies have shown that the brain of patients with gastrointestinal disease differ both structurally and functionally from that of controls. Highly somatizing diverticular disease (HSDD) patients were also shown to differ from low somatizing (LSDD) patients functionally. This study aimed to investigate how they differed structurally.
Four diseases subgroups were studied in a cross-sectional design: 20 patients with asymptomatic diverticular disease (ADD), 18 LSDD, 16 HSDD, and 18 with irritable bowel syndrome. We divided DD patients into LSDD and HSDD using a cutoff of 6 on the Patient Health Questionnaire 12 Somatic Symptom (PHQ12-SS) scale. All patients underwent a 1-mm isotropic structural brain MRI scan and were assessed for somatization, hospital anxiety, depression, and pain catastrophizing. Whole brain volumetry, cortical thickness analysis and voxel-based morphometry were carried out using Freesurfer and SPM.
We observed decreases in gray matter density in the left and right dorsolateral prefrontal cortex (dlPFC), and in the mid-cingulate and motor cortex, and increases in the left (19, 20) and right (19, 38) Brodmann Areas. The average cortical thickness differed overall across groups (P = .002) and regionally: HSDD > ADD in the posterior cingulate cortex (P = .03), HSDD > LSDD in the dlPFC (P = .03) and in the ventrolateral PFC (P < .001). The thickness of the anterior cingulate cortex and of the mid-prefrontal cortex were also found to correlate with Pain Catastrophizing (Spearman\'s ρ = 0.24, P = .043 uncorrected and Spearman\'s ρ = 0.25, P = .03 uncorrected).
This is the first study of structural gray matter abnormalities in diverticular disease patients. The data show brain differences in the pain network.

Catastrophizing is known to be associated with lower analgesia and results in total knee arthroplasty justifying its evaluation. The aim of this study is to evaluate the correlation between the functional status and the catastrophizing in patients with knee osteoarthritis.
We included patients consulting for knee osteoarthritis one of the three general practitioners participating in the study or a rheumatologist at University Hospital of Besançon. We excluded those with surgical indication. For each patient we registered the epidemiological data, the radiographic stage, the Lequesne index and the Pain Catastrophizing Score (PCS). The correlation between the different scores was assessed with a Spearman test.
Hundred patients were included, 50 patients consulting a general practitioner and 50 consulting a rheumatologist, between November 2015 and April 2016. There were mainly women (57%) with a mean age of 64.8±1.17 years old. The mean radiographic stage was 2.66±0.11 on the Kellgren and Lawrence scale. The Mean PCS was 12.98±1.18 and the mean Lequesne index was 10.46±0.47. Patients seen by rheumatologists had a more important PCS score than those seen by general practitioners, although these patients had statistically equivalent radiographic scale and Lequesne index. There was a weak correlation (r=0.3, P=0.006) between the Lequesne index and the radiographic scale but no correlation between the PCS and the radiographic scale. However, the correlation between the PCS and the Lequesne index was moderate (r=0.47; P<0.0001).
Psychological factors like catastrophizing correlated with Lequesne index.
