RESUMEN

Atopic dermatitis (AD) is a highly prevalent chronic inflammatory skin disease representing a major source of global disability burden. Disease-modifying therapies are showing promise in chronic inflammatory disorders such as rheumatoid arthritis and Crohn's disease with method and timing of initial treatment impacting long-term disease outcomes. Whether disease-modifying therapies, specifically those used as an early interventional approach, impacts disease course and comorbidity development in AD is not well-understood. We reviewed the progress in disease modification strategies, emphasizing early intervention approaches in common (or proto-typical) inflammatory diseases. Although more common in other fields, disease modification approaches are becoming increasingly investigated in dermatology, though studies in AD are lacking. Despite significant limitations in ongoing and completed studies, early data are promising and suggest that both the choice and timing of early intervention approach can affect long-term disease course and comorbidity development. To best improve AD patient outcomes, more research is needed to further explore the impact of early disease-modifying therapies. Future studies should focus on identifying the most effective approaches and extend the early results to a more inclusive set of comorbidities and longer-term outcomes.

RESUMEN

The Harmonising Outcome Measures for Eczema (HOME) initiative established a core outcome set (COS) for atopic eczema (AE) clinical trials in 2019. This set encompasses four core outcome domains and corresponding measurement instruments: clinical signs (EASI), patient-reported symptoms (POEM and NRS 11 point for worst itch over the last 24 h), quality of life (DLQI/CDLQI/IDQoLI), and long-term control (Recap or ADCT). Following its roadmap, the HOME initiative is now focused on supporting implementation of the COS. To identify barriers and facilitators to implementation of the COS, and to guide the effort to promote COS uptake, a virtual consensus meeting was held over 2 days (September 25-26, 2021) attended by 55 participants (26 healthcare professionals, 16 methodologists, 5 patients, 4 industry representatives, and 4 students). Implementation themes were identified by a pre-meeting survey distributed to HOME members, presentations, and whole-group discussion. Participants were divided into five multi-professional small groups which ranked their top 3 most important themes, followed by whole-group discussion and anonymous consensus voting (consensus criteria: < 30% disagreement). Three most important implementation themes were identified and agreed upon: (1) awareness and stakeholder engagement, (2) universal applicability of the COS, and (3) ensuring minimum administrative burden. Working groups to address these issues are now a priority for the HOME initiative. The results from this meeting will inform the development of a HOME Implementation Roadmap in an effort to support other COS groups planning for effective implementation of their core sets.

RESUMEN

Twenty-seven operations for Cushing's syndrome were reviewed. Included were five cases of adenoma and 22 of adrenal cortical hyperplasia. Preoperative laboratory data, particularly the metyrapone test, were highly accurate in distinguishing adenoma from hyperplasia. Bilateral flank incisions are preferable to the transabdominal approach, with fewer complications, less postoperative ileus, and shorter hospital stays. The inability to inspect both glands simultaneously is of little consequence because biochemical testing data are sufficiently accurate to obviate the need for gross evaluation. The use of perioperative prophylaxis seems to be of importance for preventing thromboembolism in these hypercoagulable patients. The preoperative use of adrenal cortical blocking agents has not proved to yield significant advantages.

RESUMEN

"Algorithms for a stochastic population process, based on assumptions underlying general age-dependent branching processes in discrete time with time inhomogeneous laws of evolution, are developed through the use of a new representation of basic random functions involving birth cohorts and random sums of random variables. New algorithms provide a capability for computing the mean age structure of the process as well as variances and covariances, measuring variation about means. Four exploratory population projections, testing the implications of the algorithms for the case of time-homogeneous laws of evolution, are presented. Formulas extending mean and variance functions for unit population projections...are also presented. These formulas show that, in population processes with non-random laws of evolution, stochastic fluctuations about the mean function are negligible when initial population size is large. Further extensions of these formulas to the case of randomized laws of evolution suggest that stochastic fluctuations about the mean function can be significant even for large initial populations."

RESUMEN

Adjustable sutures allow eye muscle positions to be changed following strabismus surgery, when the patient is awake and able to cooperate in muscle balance testing. Bow-tie-knot and sliding-handle sutures can be adjusted within 24 hours after surgery. Scleral traction sutures, which can be used to fix the globe to periorbital tissues during postoperative healing, can be adjusted for up to 14 days after surgery. We describe these techniques as well as an adjustable loop suture for conjunctival closure.

RESUMEN

A parametric algorithm was developed for computing model cohort and period survival functions used in making projections of human populations. Two levels of parameters were used in developing the algorithm. The algorithm provides a method for calculating model period survival functions as a function of an expectation of life at birth; model cohort survival functions are calculated as a function of a time series of period expectations of life at birth. Expectations of life at birth ranging from about 35 to 110 years in both sexes may be accommodated by the algorithm.

RESUMEN

Ammonium production in the presence of specific inhibitors of sulfate reduction and methanogenesis was investigated in six marine sediments which differed in bulk properties and organic matter input. In all cases, little effect of the inhibitors on ammonium production was observed, although sulfate reduction was suppressed by molybdate. This gives evidence that the processes of fermentation and hydrolysis are of primary importance in ammonium generation at the sites studied. Although sulfate reduction rates may appear to be coupled to ammonium production rates, sulfate reduction does not necessarily contribute directly to generation of ammonium in marine environments.

RESUMEN

An ovarian lipid cell tumor without Reinke's crystalloids in a woman with secondary amenorrhea, minimal hirsutism, and elevated 17-ketosteroid excretion was studied by light and electron microscopy. Tumor cells were found in small clumps or scattered singly within a collagenous matrix. The cytoplasm of the tumor cells contained abundant smooth endoplasmic reticula, numerous mitochondria with tubular cristae, lipid droplets, lysosomal dense bodies, and concentric membranous whorls, characteristic of steroidogenic cells. In addition, "peripheral canalicular systems" were found at the outer margins of the nests of the tumor cells. These "peripheral canalicular systems" were bordered by the cell membranes and the surrounding collagenous stroma into which microvilli projected. Since the intercellular canalicular system present between the tumor cells was continuous with the "peripheral canalicular system," both systems probably have a common function related to steroid metabolism. The intercellular and "peripheral" canalicular systems and cytoplasmic microfilaments found in this tumor suggest that this ovarian lipid cell tumor was derived from the ovarian stroma.

RESUMEN

The University Group Diabetes Program is a long-term prospective clinical trial designed to evaluate the effects of various hypoglycemic agents on vascular complications in patients with asymptomatic adult-onset diabetes. Mortality and blood glucose levels were determined as well as certain nonfatal events for patients assigned to diet alone or to either of two insulin treatment regimens. Lower levels of blood glucose with mean values close to normoglycemia were achieved in the treatment group in which the insulin dosage was adjusted to achieve normoglycemia compared with the levels achieved in patients treated with diet alone or with a fixed dose of insulin. In spite of differences in blood glucose levels among the treatment groups, there were only minor differences in the occurrence of fatal or nonfatal events.
