Active clinical trials for "Hyperplasia"

The risk of adrenal insufficiency in patients with nonclassical congenital adrenal hyperplasia due to 21-hydroxylase deficiency is not well documented. Indication of cortisol replacement therapy in situation of acute stress or at long term is thus controversial. The mineralocorticoid reserve of these patients has never been evaluated. Hypothesis: The glucocorticoid and mineralocorticoid function of the adrenal glands in women with nonclassical 21-hydroxylase deficiency is comparable with the adrenal functions of healthy age- sexe- and BMI-matched subjects.

Prognostic factor in the patients with benign prostatic hyperplasia (BPH) who undergo holmium laser enucleation of the prostate

The purpose of this study is to advance our knowledge of the factors that contribute to the development of bronchopulmonary dysplasia (BPD), a chronic lung affecting premature infants. Specifically, the investigators will determine the complexity of the gut microbiota, the genera of the bacteria that naturally live in the gut, and determine if the relative diversity of the gut bacteria is a prognostic indicator of BPD. To accomplish this, the investigators propose to characterize the microbiota of human premature newborns with BPD, then validate this potential mechanism in mice. The investigators will enroll very low birthweight premature infants admitted to the neonatal intensive care units (NICU) at Le Bonheur Children's Hospital and Regional One Health that are at high risk to develop BPD. A cohort of well full term newborns will also be enrolled. Non-invasive stool samples will be obtained weekly over the first month of life. Infants that eventually develop BPD will be paired with infants that did not develop BPD. Stool samples from these infants will be sent for analysis. The investigators expect that reduced complexity of the gut microbiome is associated with BPD. The investigators will model the contribution of reduced microbiome complexity to the risk to develop BPD or death, as well as the association with disease severity. The project investigates important factors leading to the development of BPD, and has the potential to directly translate to therapy for the most significant pulmonary complication of prematurity.

Hyponatremic hypovolemia is a frequent complication of transurethral resection of the prostate gland (TURP). Copeptin has been established as is a surrogate marker of vasopressin and is measured useful for thea clinical assessment of various sodium and water disturbances. The aim of our the study was to assess the utility of serum concentration of copeptin (CPP) and brain natriuretic peptide (NT-proBNP) for the prediction of postoperative alterations of serum sodium concentration. Study population comprised 43 patients with benign prostatic hyperplasia (BPH) undergoing transurethral resection of the prostate gland. In a forward stepwise multiple regression only serum copeptin before the surgery and the duration of TURP significantly explained the variation of sodium concentration for 12 hours from the start of the surgery. Serum NT-proBNP before the surgery did not predict hyponatremia 12 hours after TURP.Conclusion Serum copeptin before TURP surgery but not NT-proBNP may be a clinically useful marker of a decrease of serum sodium after TURP surgery.

The aim of this study is to determine that for hepatic dysplastic nodules in patients with chronic hepatitis B, instead of enhanced follow-up, whether early minimally-invasive ablation therapy can reduce the incidence of hepatocellular carcinoma.

The aim of this study is to determine if fungal colonization is associated to severe bronchopulmonary dysplasia in premature infants less than 29 weeks of gestation, and to determine if an association exists between fungal colonization and complications of prematurity and death.

This study compared the performance of different models of multiple b-value DWI in diagnosing prostate cancer.

This retrospective study aims to assess the economic impact of early initiation of 5-alpha-reductase inhibitor (5ARI) therapy in patients with enlarged prostate (EP) receiving 5ARI and alpha-blocker (AB) combination therapy. Both the Integrated Health Care Information Solutions and PharMetrics databases will be utilized for this study (2000-2007).

This retrospective study aims to assess the impact of early vs delayed 5-alpha-reductase inhibitor (5ARI) therapy in patients with BPH on alpha-blocker (AB) therapy and the risk of acute urinary retention (AUR), prostate-related surgery, and emergency surgery (defined as prostate surgery occurring within 30 days of AUR). The MarketScan database will be utilized for this study (2000-2008).

This retrospective study aims to assess the clinical and economic impact of early initiation of 5-alpha-reductase inhibitor (5ARI) therapy in patients with enlarged prostate (EP) receiving 5ARI monotherapy or combination therapy with an alpha-blocker (AB) compared to late initiation of 5ARI therapy in patients receiving combination therapy. The Henry Ford Health System databases will be utilized for this study (2000-2008).
