Towards global consensus on core outcomes for hidradenitis suppurativa research: an update from the HISTORIC consensus meetings I and II

BACKGROUND

A core outcomes set (COS) is an agreed minimum set of outcomes that should be measured and reported in all clinical trials for a specific condition. Hidradenitis suppurativa (HS) has no agreed-upon COS. A central aspect in the COS development process is to identify a set of candidate outcome domains from a long list of items. Our long list had been developed from patient interviews, a systematic review of the literature and a healthcare professional survey, and initial votes had been cast in two e-Delphi surveys. In this manuscript, we describe two in-person consensus meetings of Delphi participants designed to ensure an inclusive approach to generation of domains from related items.

OBJECTIVES

To consider which items from a long list of candidate items to exclude and which to cluster into outcome domains.

METHODS

The study used an international and multistakeholder approach, involving patients, dermatologists, surgeons, the pharmaceutical industry and medical regulators. The study format was a combination of formal presentations, small group work based on nominal group theory and a subsequent online confirmation survey.

RESULTS

Forty-one individuals from 13 countries and four continents participated. Nine items were excluded and there was consensus to propose seven domains: disease course, physical signs, HS-specific quality of life, satisfaction, symptoms, pain and global assessments.

CONCLUSIONS

The HISTORIC consensus meetings I and II will be followed by further e-Delphi rounds to finalize the core domain set, building on the work of the in-person consensus meetings.

Evidence for anti-inflammatory effects of firocoxib administered to mares with experimentally induced placentitis

PROBLEM

Minimal evidence exists supporting therapeutic selections for equine placentitis. The goal of this study was to characterize the anti-inflammatory effects of firocoxib when administered to mares with placentitis.

METHODS

Mares (gestation D270-300) were assigned to: INFECT (n = 6; placentitis, no treatment), FIRO (n = 6; placentitis, firocoxib, 0.1 mg/kg, PO, daily), and NORM (n = 6; no infection/treatment). Allantoic fluid (8 hours, 24 hours, birth) and amniotic fluid (birth) were collected from mares after infection. Concentrations of IL-1β, IL-6, TNF-α, IL-10, PGF_2α , and PGE₂ in fluids were measured by ELISA. mRNA expression of IL-1β, IL-6, TNF-α, IL-8, IL-10, matrix metalloproteinases (MMPs) -1, 3, and 9 in fetal membranes/fetuses was quantified using real-time PCR.

RESULTS

Allantoic TNF-α concentrations were lowest in FIRO at 8 hours and 24 hours post-infection; IL-6 concentrations were lower in FIRO than NORM at 8 hours, lower in FIRO than INFECT at 24 hours post-inoculation, and lower in NORM than FIRO or INFECT at birth. Marginal mean allantoic IL-β and IL-10 concentrations were lower in FIRO and NORM than INFECT. Amniotic fluid cytokines were lowest in NORM with all measurements in that group being below the limit of detection. Allantoic PGF_2α concentrations were lower in FIRO and INFECT than NORM at 8 hours post-inoculation, and lower in FIRO than INFECT or NORM at 24 hours post-inoculation. Allantoic PGE₂ concentrations were lower in FIRO than INFECT. Amniotic PGF_2α and PGE₂ concentrations were lower in NORM than INFECT. In fetal membranes, group differences with respect to IL-1β, IL-6, IL-8, and MMP1 were dependent on tissue type.

CONCLUSIONS

Data suggest a suppressive effect of firocoxib administration on cytokine and prostaglandin production in mares with placentitis.

Dental Trauma and Disease in 34 Professional Athletes

In brief: As part of the preseason general physical examination, 34 football players were given dental examinations. In addition to routine dental caries and gingival inflammation, 18 athletes had dental problems that could potentially interfere with the competitive season: retained root tips, abscessed teeth, pulpally exposed carious teeth, and seriously impacted third molars. Nine players had sustained injuries to the maxillary anterior teeth, many of which could have been prevented by customized mouth guards.

Dental service established with minimum effort

Providing dental care to handicapped patients and children is a natural role for hospitals and one that can be undertaken without the need for lavish expenditures.

Incorporating care for the special patient into general dental practice

The training of general dental practitioners in a program that emphasizes the care of the special patient is described. Each trainee donates one day a week to the Illinois Masonic Medical Center, which pays all practice expenses, and a referral network is being developed among those who have completed the course.

Avoiding patient injury during general anesthesia

Attention to detail when preparing a dental patient for rehabilitation utilizing general anesthesia will prevent a variety of positional and traumatic injuries. The dentist and anesthesiologist must anticipate potential hazards to the unconscious patient.
