Polycystic ovary syndrome represents 80% of anovulatory infertility cases. Treatment initially includes preconception guidelines, such as lifestyle changes (weight loss), folic acid therapy to prevent the risk of fetal neural tube defects and halting the consumption of tobacco and alcohol. The first-line pharmacological treatment for inducing ovulation consists of a clomiphene citrate treatment for timed intercourse. The second-line pharmacological treatment includes the administration of exogenous gonadotropins or laparoscopic ovarian surgery (ovarian drilling). Ovulation induction using clomiphene citrate or gonadotropins is effective with cumulative live birth rates of approximately 70%. Ovarian drilling should be performed when laparoscopy is indicated; this procedure is typically effective in approximately 50% of cases. Finally, a high-complexity reproduction treatment (in vitro fertilization or intracytoplasmic sperm injection) is the third-line treatment and is recommended when the previous interventions fail. This option is also the first choice in cases of bilateral tubal occlusion or semen alterations that impair the occurrence of natural pregnancy. Evidence for the routine use of metformin in infertility treatment of anovulatory women with polycystic ovary syndrome is not available. Aromatase inhibitors are promising and longer term studies are necessary to prove their safety.  相似文献

The large number of pharmacological agents available to treat type 2 diabetes (T2D) makes choosing the optimal drug for any given patient a complex task. Because newer agents offer several advantages, whether and when sulphonylureas (SUs) should still be used to treat T2D is controversial. Published treatment guidelines and recommendations should govern the general approach to diabetes management. However, expert opinions can aid in better understanding local practices and in formulating individual choices. The current consensus paper aims to provide additional guidance on the use of SUs in T2D. We summarize current local treatment guidelines in European countries, showing that SUs are still widely proposed as second-line treatment after metformin and are often ranked at the same level as newer glucose-lowering medications. Strong evidence now shows that sodium-glucose co-transporter-2 inhibitors (SGLT-2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) are associated with low hypoglycaemia risk, promote weight loss, and exert a positive impact on vascular, cardiac and renal endpoints. Thus, using SUs in place of SGLT-2is and GLP-1RAs may deprive patients of key advantages and potentially important cardiorenal benefits. In subjects with ascertained cardiovascular disease or at very high cardiovascular risk, SGLT-2is and/or GLP-1RAs should be used as part of diabetes management, in the absence of contraindications. Routine utilization of SUs as second-line agents continues to be acceptable in resource-constrained settings.  相似文献

We reviewed the records of 151 patients diagnosed with American cutaneous leishmaniasis (ACL) from 1993 to 2009 in the municipality of Japura, Paraná, Brazil. Gender, age, occupation, place of residence, location of lesions, type and number of lesions were analyzed. The prevalence rate of ACL was 11.5/10,000 hab, of which 84.7% were male, 58.3% lived in rural area and 49.0% were farmers. The most frequent age group was between 30 to 39 years (26.6%). Skin lesions occurred in 92.7% of the patients with predominance in the lower limbs (23.9%) and 49.1% of the records did not include the number of lesions location due to incomplete filling. A single ulceration was present in 44.4%. Japurá is an endemic area for ACL, requiring public actions and preventive education.  相似文献

ABSTRACT: Fibrous dysplasia is a benign fibro-osseous disease that affects 1 or more bones. Deformities leading to aesthetic and functional disorders are observed in almost all cases. Plastic surgery is often recommended when the jaws are involved. Monostotic fibrous dysplasia of the mandible is an unusual manifestation of the disease that is usually benign, occurs in young individuals, and is managed by conservative curettage or debridement, such as surgical sculpting. The authors report a case of a 15-year-old patient with a large monostotic fibrous dysplasia located in the right mandible, which was treated by contouring bone. The lesion did not recur on follow-up for 4 years after the surgical procedure.  相似文献
