Studies on epidemiology of female sexual problems consistently indicate high prevalence rates worldwide, suggesting that this clinical presentation should be considered as a public health concern. However, there are no published studies on prevalence of sexual problems in Portugal. The present study investigated the prevalence, severity, and comorbidity of female sexual problems in a Portuguese community sample. In addition, the authors assessed the role of sociodemographic predictors of women's sexual difficulties. The authors recruited 500 women using quota methods to resemble the Portuguese population according to its demographic characteristics. Participants answered to the Female Sexual Function Index and to a sociodemographic questionnaire. Findings indicated that 37.9% of the Portuguese women reported symptoms of sexual problems. Symptoms of lack of sexual desire was the most frequent sexual difficulty with 25.4% of the women reporting low desire most times or always, followed by symptoms of orgasmic (16.8%), sexual arousal (15.1%), and lubrication difficulties (12.9%), dyspareunia (9.8%), and vaginismus (6.6%). Results indicated that age was a significant predictor of female sexual problems. Results also indicated that symptoms of female sexual problems are a significant health concern in Portugal, suggesting that public policies should be developed to promote sexual health.

A functional polymorphism within butyrophilin-like 2 (BTNL2) gene has been described as a potential risk factor for sarcoidosis. The association between chronicity and the rs2076530 SNP A allele has also been reported. This study evaluates the BTNL2 rs2076530 G/A allele associations with sarcoidosis susceptibility and disease evolution in a Portuguese cohort of patients. A case-control study of 151 patients and 150 controls was performed. Allele frequencies were compared with Chi-square test in a univariate analysis and with logistic regression in a multivariate analysis. BTNL2 rs206530 A allele frequencies were significantly higher in sarcoidosis with no linkage disequilibrium with HLA-DRB1 alleles, except in the subgroup of patients with Löfgren syndrome where the determinant allele was HLA-DRB1*03. The A allele was also increased in those with isolated thoracic disease, with no differences regarding radiological stages or disease evolution. HLA-DRB1*03, besides the association with Löfgren syndrome was significantly related with disease resolution. Our data confirms the association of BTNL2 rs2076530 A allele with sarcoidosis susceptibility in a Portuguese population. We found independent genetic risk factors in clinically distinct disease phenotypes: BTNL2 rs2076530 A allele in patients without Löfgren syndrome or with isolated thoracic disease, and HLA-DRB1*03 in Löfgren syndrome or disease resolution.

Introduction Conservative and dysfunctional sexual beliefs are commonly associated with sexual problems among heterosexual men and women. However, little is known about the role of sexual beliefs in sexual problems in gay men and lesbians. Aim The present study aimed at analyzing the role of sexual beliefs in sexual dysfunction in a sample of heterosexual and homosexual men and women. Main Outcome Measures Participants answered questions about self-perceived sexual problems and completed the Sexual Dysfunctional Beliefs Questionnaire. Methods Two hundred twelve men (106 gay) and 192 women (96 lesbian) completed a Web survey. Results Findings indicated that men with sexual dysfunction (regardless of sexual orientation) reported significantly more conservative beliefs and more erroneous beliefs related to partner's sexual satisfaction compared with sexually healthy men. Also, gay men with sexual dysfunction (but not heterosexual men) scored higher on belief in sex as an abuse of men's power compared with healthy controls. In addition, heterosexual men scored higher on “macho” beliefs, beliefs regarding partner's sexual satisfaction, and partner's power, compared with gay men. For women, a main effect was found for sexual orientation, with lesbian women scoring higher on sexual desire as a sin, age-related beliefs, and affection primacy and lower on beliefs related to motherhood primacy. Conclusions Overall, findings suggest that dysfunctional sexual beliefs may play a role as vulnerability factors for sexual dysfunction regardless of sexual orientation, particularly in men.

Objective. Twelve families that were multiply affected with diffuse idiopathic skeletal hyperostosis (DISH) and/or chondrocalcinosis, were identified on the island of Terceira, The Azores, potentially supporting the hypothesis that the 2 disorders share common etiopathogenic factors. The present study was undertaken to investigate this hypothesis.Methods. One hundred three individuals from 12 unrelated families were assessed. Probands were identified from patients attending the Rheumatic Diseases Clinic, Hospital de Santo Espírito, in The Azores. Family members were assessed by rheumatologists and radiologists. Radiographs of all family members were obtained, including radiographs of the dorsolumbar spine, pelvis, knees, elbows, and wrists, and all cases were screened for known features of chondrocalcinosis.Results. Ectopic calcifications were identified in 70 patients. The most frequent symptoms or findings were as follows: axial pain, elbow, knee and metacarpophalangeal (MCP) joint pain, swelling, and/or deformity, and radiographic enthesopathic changes. Elbow and MCP joint periarticular calcifications were observed in 35 and 5 patients, respectively, and chondrocalcinosis was identified in 12 patients. Fifteen patients had sacroiliac disease (ankylosis or sclerosis) on computed tomography scans. Fifty-two patients could be classified as having definite (17%), probable (26%), or possible (31%) DISH. Concomitant DISH and chondrocalcinosis was diagnosed in 12 patients. Pyrophosphate crystals were identified from knee effusions in 13 patients. The pattern of disease transmission was compatible with an autosomal-dominant monogenic disease. The mean age at which symptoms developed was 38 years.Conclusion. These families may represent a familial type of pyrophosphate arthropathy with a phenotype that includes peripheral and axial enthesopathic calcifications. The concurrence of DISH and chondrocalcinosis suggests a shared pathogenic mechanism in the 2 conditions.

A recent genome-wide association study detected a protective effect for the annexin A11 rs1049550*T allele (R230Cvariant) in susceptibility to sarcoidosis. We evaluated the association between rs1049550 C/T and sarcoidosis susceptibility, distinct disease phenotypes and evolution in a Portuguese population. We performed a case-control study of 208 patients and 197 healthy controls. Samples were genotyped for rs1049550 C/T using real-time polymerase chain reaction. The frequency of the annexin A11 rs1049550*T allele was significantly lower in patients than in controls (33.2 vs 44.9%, P < 0.001). Odds ratio of 0.52 and 0.44 were obtained, respectively for carriers of one (CT) and two (TT) copies normalized to the CC wild-type genotype (P < 0.001). There were no significant differences in patients with and without Löfgren syndrome. A significant increase in the frequency of the T allele was observed in patients with bronchoalveolar lavage (BAL) fluid neutrophilia (P = 0.04). No significant associations were seen for lung function pattern, radiological stages or different forms of disease evolution. Our study confirms that rs1049550*T allele exerts a significant protective effect on sarcoidosis susceptibility. Given the role of annexin A11 in cell division, apoptosis and neutrophil function, this polymorphism may affect key elements of granulomatous and interstitial inflammation in sarcoidosis.

Personality traits, namely neuroticism, have been suggested as vulnerability factors for the development and maintenance of sexual dysfunction in heterosexual samples. However, no evidence was found regarding homosexual samples. This study aimed to analyze the differences on personality traits between heterosexual and homosexual men and women with and without sexual problems. Participants were 285 individuals (142 men, 143 women) who completed a web-based survey. Participants answered the NEO Five-Factor Inventory, the Brief Symptomatology Inventory, and questions regarding sexual problems. The groups of men and women with and without sexual problems were matched for sociodemographic variables. A 2 (Group) × 2 (Sexual Orientation) multivariate analysis of covariance was conducted separately for each gender. Results indicated a significant main effect for group and for sexual orientation in male and female samples. Men with sexual problems scored higher on neuroticism, whereas women with sexual problems scored higher on neuroticism and lower on extraversion when compared with healthy controls, regardless of sexual orientation. In addition, gay men scored higher on neuroticism and lesbian women scored higher on conscientiousness compared with the heterosexual groups. The present findings emphasize the central role of neuroticism on sexual problems in both men and women regardless of sexual orientation.
