Chronic Pain and Depression in the Quality of Life of Women With Migraine - A Controlled Study

Background. Migraine is comorbid to depression and widespread chronic pain (WCP), but the influence of these conditions on the health-related quality of life (HRQoL) of individuals with episodic (EM) and chronic migraine (CM) is poorly understood. Objective.-To assess the prevalence of depressive symptoms and WCP in individuals with EM and CM, as well as to estimate the joint impact of these conditions on the HRQoL of these individuals. Methods.-All women aged 18 to 65 years with a first diagnosis of EM or CM from September of 2006 to September of 2008 seen in an outpatient headache service were invited to participate. They were asked to attend a separate appointment in the service, and to bring another woman of similar age that also agreed to participate. Depressive symptoms were assessed using the Beck Depression Inventory. Questions about WCP followed the protocol of the American College of Rheumatology. HRQoL was assessed using the Short-Form 36 (SF-36). Multivariate analysis modeled HRQoL as a function of headache status, depressive symptoms, and pain, using quantile regression. Results.-Sample consisted of 179 women, 53 in the EM group, 37 in the CM group and 89 in control group. Groups did not differ by demographics. Mean scores of SF-36 were 53.6 (standard deviation [SD] = 23.5) for EM, 44.2 (SD = 18.5) for CM and 61.8 (SD = 21.5) for controls. In multivariate analysis, SF-36 scores were predicted by a CM status (P =.02; -10.05 [95% CI -18.52; -1.58]) and by a Beck Depression Inventory score (P <.01; -1.27 [95% CI -1.55; -0.99]). The influence of WCP in the SF-36 scores approached significance (P =.08; -0.78 [95% CI -1.64; 0.88]). Age did not contribute to the model. Conclusion.-Women with migraine are at an increased chance of WCP, and the chance increases as a function of headache frequency. Both depressive symptoms and CM independently predict HRQoL status.

Lupus erythematosus panniculitis in children and adolescents

Introduction: Lupus erythematosus panniculitis (LEP) or lupus erythematosus profundus is a rare form of chronic cutaneous manifestation affecting both adults and pediatric patients. The prevalence of this manifestation was seldom reported in juvenile systemic lupus erythematosus (JSLE). Case reports: From January 1983 to December 2010, 5,506 patients were followed at the Pediatric Rheumatology Unit of our University Hospital and 278 (5%) of them met the American College of Rheumatology classification criteria for JSLE. Two (0.7%) of them had LEP at JSLE onset. These two cases had tender deep inflammatory subcutaneous nodules or plaques at the time of diagnosis, and the histopathologic pattern evidenced lobular or mixed panniculitis with lymphocytic inflammatory cells of the fat lobule. Treatments for LEP included mainly antimalarials, systemic corticosteroids and sunscreen protection. One male patient required thalidomide and immunosuppressive drugs, including mycophenolate mofetil, cyclosporin and intravenous cyclophosphamide. However, skin lesions improved only after rituximab treatment. Discussion: LEP was rarely observed in our cohort of JSLE patients as the first lupus manifestation. Anti-CD20 monoclonal antibody therapy may be an option for refractory LEP treatment in children.

Invasive aspergillosis: a severe infection in juvenile systemic lupus erythematosus patients

Infections are an important cause of morbidity and mortality in juvenile systemic lupus erythematosus (JSLE). Among them, invasive aspergillosis (IA), which is usually related to immunosuppressed patients, has been rarely reported in JSLE. From 1983 to 2011, 5604 patients were followed at our institution and 283 (5%) met the American College of Rheumatology (ACR) classification criteria for SLE. Six (2.1%) of our JSLE patients had IA. One of them was previously reported and five will be described herein. Four of them were female. The median age at JSLE diagnosis was 12 years (8-16) and the median interval between diagnosis of JSLE and IA was 6 months (1-38). All had pulmonary involvement and three of them had systemic involvement. The median Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) was 19 (7-22). Diagnosis of IA was performed by isolation of Aspergillus spp., two in bronchoalveolar lavage culture and by way of autopsy in the others. All of them were treated with corticosteroids and/or immunosuppressive drugs at IA diagnosis (azathioprine and/or intravenous cyclophosphamide). They all required treatment in the pediatric intensive care unit with mechanical ventilation and antifungal therapy (fluconazole, amphotericin B, itraconazole and/or voriconazole); nonetheless, none of them survived. In conclusion, this was the first report that evaluated the prevalence of IA in a large population of JSLE patients from a tertiary pediatric hospital, and clearly showed the severity of the outcome, especially in patients with active disease and treated with immunosuppressive agents. This study reinforces the importance of early diagnosis and treatment with certain antifungals, especially in critically ill patients. Lupus (2012) 21, 1011-1016.

Genetic analysis of kernel oil content in tropical maize with design III and QTL mapping

Oil content and grain yield in maize are negatively correlated, and so far the development of high-oil high-yielding hybrids has not been accomplished. Then a fully understand of the inheritance of the kernel oil content is necessary to implement a breeding program to improve both traits simultaneously. Conventional and molecular marker analyses of the design III were carried out from a reference population developed from two tropical inbred lines divergent for kernel oil content. The results showed that additive variance was quite larger than the dominance variance, and the heritability coefficient was very high. Sixteen QTL were mapped, they were not evenly distributed along the chromosomes, and accounted for 30.91% of the genetic variance. The average level of dominance computed from both conventional and QTL analysis was partial dominance. The overall results indicated that the additive effects were more important than the dominance effects, the latter were not unidirectional and then heterosis could not be exploited in crosses. Most of the favorable alleles of the QTL were in the high-oil parental inbred, which could be transferred to other inbreds via marker-assisted backcross selection. Our results coupled with reported information indicated that the development of high-oil hybrids with acceptable yields could be accomplished by using marker-assisted selection involving oil content, grain yield and its components. Finally, to exploit the xenia effect to increase even more the oil content, these hybrids should be used in the Top Cross((TM)) procedure.

Persistent Periodontal Disease Hampers Anti-Tumor Necrosis Factor Treatment Response in Rheumatoid Arthritis

Objective: This study aimed to evaluate prospectively the influence and the evolution of periodontal disease (PD) in rheumatoid arthritis (RA) patients submitted to anti-tumor necrosis factor (TNF) therapy. Methods: Eighteen patients with RA (according to the American College of Rheumatology criteria) were assessed for PD before (BL) and after 6 months (6M) of anti-TNF treatment: 15 infliximab, 2 adalimumab, and 1 etanercept. Periodontal assessment included plaque and gingival bleeding indices, probing pocket depth, cementoenamel junction, and clinical attachment level. Rheumatologic evaluation was performed blinded to the dentist's assessment: demographic data, clinical manifestations, and disease activity (Disease Activity Score using 28 joints [DAS28], erythrocyte sedimentation rate [ESR], and C-reactive protein [CRP]). Results: The median age and disease duration of patients with RA were 50 years (25-71 y) and 94% were female. Periodontal disease was diagnosed in 8 patients (44.4%). Comparing BL to 6M, periodontal parameters in the entire group remained stable (P > 0.05) throughout the study (plaque and gingival bleeding indices, probing pocket depth, cementoenamel junction, and clinical attachment level), whereas an improvement in most analyzed RA parameters was observed in the same period: DAS28 (5.5 vs. 3.9, P = 0.02), ESR (21 vs. 12.5 mm/first hour, P = 0.07), and CRP (7.8 vs. 2.8 mg/dL, P = 0.25). Further analysis revealed that this improvement was restricted to the group of patients without PD (DAS28 [5.5 vs. 3.6, P = 0.04], ESR [23.0 vs. 11.5 mm/first hour, P = 0.008], and CRP [7.4 vs. 2.1, P = 0.01]). In contrast, patients with PD had lack of response, with no significant differences in disease activity parameters between BL and 6M: DAS28 (5.2 vs. 4.4, P = 0.11), ESR (17.0 vs. 21.0, P = 0.56), and CRP (9.0 vs. 8.8, P = 0.55). Conclusions: This study supports the notion that PD may affect TNF blocker efficacy in patients with RA. The possibility that a sustained gingival inflammatory state may hamper treatment response in this disease has high clinical interest because this is a treatable condition.

Dangerous waters: outbreak of eye lesions caused by fresh water sponge spicules

Purpose To describe an extremely uncommon outbreak of eye lesions in a specific area of the Brazilian Amazonia. Methods Prospective noncomparative case series. Fifty-nine patients who developed eye lesions after swimming in the Araguaia river of Tocantins state in Brazil were examined. A team of ophthalmologists equipped with a slit-lamp, gonioscopic lenses, and indirect ophthalmoscopy performed full eye examination. Analysis of the flora and fauna of the river water was undertaken by a group of experts. Results and Conclusions Eighty-three eyes were affected. The most common lesions were corneal opacities seen in 34 eyes and conjunctival nodules diagnosed in 12 eyes. Severe visual acuity loss was detected in seven children with unilateral anterior chamber lesions. Spicules of the sponge species Drulia uruguayensis and Drulia ctenosclera were found inside three blind eyes that have been enucleated for diagnostic purposes. All eye lesions could be attributed to an outbreak of foreign bodies from fresh water sponges. Organic enrichment of the water resulting from the absence of sanitation probably was the key factor, which initiated a cycle of ecological imbalance that provoked human disease.
