Diabetes mellitus is a chronic disease characterized by high social, economic and health burden, mostly due to the high incidence and morbidity of diabetes complications. Numerous studies have shown that optimizing metabolic control may reduce the risk of micro and macrovascular complications related to the disease, and the algorithms suggest that an appropriate and timely step of care intensification should be proposed after 3 months from the failure to achieve metabolic goals. Nonetheless, many population studies show that glycemic control in diabetic patients is often inadequate. The phenomenon of clinical inertia in diabetology, defined as the failure to start a therapy or its intensification/de-intensification when appropriate, has been studied for almost 20 years, and it is not limited to diabetes care, but also affects other specialties. In the present manuscript, we have documented the issue of inertia in its complexity, assessing its dimensions, its epidemiological weight, and its burden over the effectiveness of care. Our main goal is the identification of the causes of clinical inertia in diabetology, and the quantification of its social and health-related consequences through the adoption of appropriate indicators, in an effort to advance possible solutions and proposals to fight and possibly overcome clinical inertia, thus improving health outcomes and quality of care.
Adherence to prescribed medication is important to the management of all diseases, especially those of chronic nature. Drug effectiveness is substantially compromised by therapy nonadherence. We reviewed the available evidences on the impact of patient preferences for therapy on adherence to a prescribed treatment in chronic diseases requiring long-term treatment. A search on PubMed retrieved 699 publications, leading to a selection of 12 publications: 6 on osteoporosis, 2 on moderate-to-severe asthma, 1 on type 1 diabetes, 1 on type 2 diabetes, 1 on kidney transplantation, and 1 on atrial fibrillation. Overall, 8 studies found a positive association between patient preference and adherence to therapy, while the others found no association. In general, overall adherence was considered to be high in the published studies. The reasons for a positive association included reduced dosing frequency, route of administration, lower costs, and favorable safety profile, which is related to the diverse nature of the pathology and its type and duration of treatment. A literature review suggests that achieving good adherence and persistence to therapy requires evaluation of patient preferences. In a period of increasingly limited resources, more effort is warranted to promote better adherence to therapy, especially when patients must self-manage their disease in the long term. Our results further highlight that insufficient attention has been given to the relationship between patient preference and adherence and point out the complex nature of adherence and the need for adequate patient education. More efforts are also needed to better understand the entity of cost savings for payers for specific treatments and the link with patient preference.
We report a case of a 66-yr-old woman with progressive hair balding, hirsutism and virilization. Gonadotropins and estradiol levels were in the postmenopausal range; total testosterone (TT), free testosterone (FT) and 17-hydroxyprogesterone (17-OHP) were elevated with dehydroepiandrosterone sulphate, androstendione and cortisol serum levels in the normal range, as 24-hr free urinary cortisol. TT, FT and 17-OHP were normalized, and FSH and LH fell to premenopausal levels on 18th day after a single i.m. injection of the GnRH analogue (GnRHa), triptorelin. Then, a diagnosis of hyperandrogenism of ovarian origin was made and bilateral ovariectomy was performed. Histological study of gonadal tissue revealed diffuse stromal hyperplasia of both ovaries with occasional nests of luteinized cells. With immunoperoxidase techniques these cells stained positively for testosterone and progesterone. One month after surgery, androgen levels were normalized together with regression of most of the clinical signs of virilization. In conclusion, our patient showed a severe virilization developed after menopause; hormonal investigations suggested a gonadotropin dependent ovarian hyperandrogenism, confirmed by histological examination; the presence of luteinized cells in the ovarian stroma was responsible for hyperandrogenism, as confirmed by the immunoperoxidase technique.
Varicocele is a common cause of male infertility; it can be treated by percutaneous retrograde embolization of the internal spermatic vein in order to improve sperm parameters and male fertility. The aim of this study was to verify the improvement of semen parameters after varicocele retrograde sclerotherapy. We evaluated 223 patients with left (206) or bilateral (17) varicocele (mean age +/- SD, 27.3 +/- 4.7 yr, range 18-37) by clinical, Doppler and seminal examinations; all the patients underwent phlebography, using 5F Cobra catheter from the right femoral vein access to the internal spermatic vein and varicocele sclerosing with Hydroxy-polyaethoxydodecanol. Doppler and seminal examinations 6 months after sclerotherapy were requested for the follow-up. Sixty-seven patients with left or bilateral varicocele who did not undergo sclerotherapy were studied as controls. Six months after sclerotherapy, a complete resolution of left varicocele was present in 172 patients (77.1%), while a partial improvement was obtained in 34 patients (15.3%). In these 206 patients seminal examination showed a significant improvement of sperm concentration (mean +/- SEM, 52.1 +/- 4.1 vs 44.2 +/- 3.6 million/ml, p = 0.002) and progressive motility (40.5 +/- 2.2 vs 33.3 +/- 2.0%, p = 0.0001), but not of normal sperm morphology (38.9 +/- 2.3 vs 37.4 +/- 2.1%, ns). In the control group no significant variations of seminal parameters were observed 6 months after the basal examination. In conclusion, varicocele retrograde sclerotherapy is a well-tolerated technique with a low cost-benefit ratio, able to improve semen parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
