Abstract Because of the increasing use of 17‐hydroxyprogesterone (17OHP) levels with the short adrenocorticotrophic hormone (ACTH) test in the detection of 21‐hydroxylase deficiency, the diagnostic efficiency of the test was evaluated in patient and family studies of congenital adrenal hyperplasia due to 21‐hydroxylase... |
PURPOSE |
To determine whether excimer laser transepithelial photoablation can reduce the initial keratocyte loss seen after manual epithelial debridement. Second, to establish the relationship between initial depth of keratocyte and stromal loss and the subsequent development of corneal haze. |
METHODS |
Five rabbits received a 5-mm diameter monocular epithelial debridement by manual scraping. An additional five rabbits received a 5-mm diameter excimer laser transepithelial photoablation to a preset (intended) depth of 60 microns to ensure complete epithelial removal and to generate a superficial stromal keratectomy in... |
RESULTS |
Manual epithelial debridement was associated with an initial loss of anterior stromal keratocytes to a depth of 108 +/- 14 microns that was followed by repopulation with migratory keratocytes. These cells showed increased reflectivity producing significant backscattering of light equivalent to clinical haze grade 1-2 (... |
CONCLUSIONS |
Excimer laser transepithelial photoablation induced significantly less keratocyte loss than manual epithelial debridement; however, photoablation was followed by a more intense inflammatory response and a greater increase in backscattering of light (haze) that was associated with increased keratocyte activation and myo... |
BACKGROUND |
Persistent pain extending beyond 6 months after breast cancer surgery when adjuvant therapies have ended is a recognised phenomenon. The evolution of postsurgery pain is therefore of interest for future patient management in terms of possible prognoses for distinct groups of patients to enable better patient informatio... |
OBJECTIVE(S) |
An analysis aimed to identify subgroups of patients who share similar time courses of postoperative persistent pain. |
DESIGN |
Prospective cohort study. |
SETTING |
Helsinki University Hospital, Finland, between 2006 and 2010. |
PATIENTS |
A total of 763 women treated for breast cancer at the Helsinki University Hospital. |
INTERVENTIONS |
Employing a data science approach in a nonredundant reanalysis of data published previously, pain ratings acquired at 6, 12, 24 and 36 months after breast cancer surgery, were analysed for a group structure of the temporal courses of pain. Unsupervised automated evolutionary (genetic) algorithms were used for patient c... |
MAIN OUTCOME MEASURES |
Clusters or groups of patients sharing patterns in the time courses of pain between 6 and 36 months after breast cancer surgery. |
RESULTS |
Three groups of patients with distinct time courses of pain were identified as the best solutions for both clustering of the pain ratings and multimodal modelling of the slopes of their temporal trends. In two clusters/groups, pain decreased or remained stable and the two approaches suggested/identified similar subgrou... |
CONCLUSION |
In the majority of patients, pain after breast cancer surgery decreased rapidly and disappeared or the intensity decreased over 3 years. However, in about a tenth of patients, moderate-to-severe pain tended to increase during the 3-year follow-up. |

OBJECTIVE |
To determine the scope, impact, and health care limitations relative to cardiovascular disease (CVD) in the Latino-Hispanic population. |
METHODS |
We reviewed MEDLINE and PubMed for studies published from January 1995 to June 2005 using a combination of search terms (epidemiology, Hispanic, CVD) and chose articles for review on the basis of direct informational relevance to the current status of preventive treatment and barriers to health care for CVD among the L... |
RESULTS |
For proactive reduction of rates of CVD among the Latino-Hispanic population in the United States, preventive interventions should be targeted. Several barriers exist to providing effective preventive care to the Latino-Hispanic community. Medical research involving the Latino-Hispanic population is sparse, many Latino... |
CONCLUSION |
The prevalence and growth of CVD in the US Latino-Hispanic community provide a clear warning that the public health problem presented by CVD in the Latino-Hispanic population is already substantial and will become much more severe in the coming decades. Actions to manage and minimize this problem are urgently needed.Op... |
The problem of space-constrained absorbers in the low frequency range constitutes an area of continuous research. Micro-perforated panels are advantageous because they can be tuned by a proper selection of their constitutive physical parameters including the diameter of the perforations |
and their separation distance, their thickness and the length of the backing cavity. However, such optimal selection is not straightforward, especially when considering multi-layer partitions. Current optimization algorithms are based on the maximization of the total absorption coefficient |
averaged over a frequency band, that requires a compromise between the bandwidth and the thickness of the control device. In this work, the problem is analysed on the basis of a causality criterion. This principle is generalized from its formulation in the field of electromagnetism to obtain |
a relation that correlates the thickness-to-bandwidth performance of a micro-perforated absorber to its total absorption coefficient. Using this relation, an optimization procedure is presented for the sequential selection of the optimal physical parameters for single-layer partitions. An |
excellent agreement has been found between the optimal values obtained by the causality criterion and those achieved by critical coupling conditions.Experimental characterization of the probability density function of the operating loads supported by urban buses in Madrid, Spain |
