Outcomes of the Subsequent Periprosthetic Joint Infection Revisions after a Failed Debridement, Antibiotics and Implant Retention: A Multicentric Study of 197 Patients.

The impact of prior unsuccessful debridement, antibiotics, and implant retention (DAIR) procedures on subsequent revisions is uncertain, with conflicting evidence. Despite 85% consensus against the second DAIR procedure following the 2018 International Consensus Meeting, a 2020 study reported high success rates for the aforementioned second DAIR procedure. We conducted a multicenter observational study reviewing data from patients with failed DAIR procedures between 2005 and 2021.

A combined debridement, antibiotics, and implant retention (DAIR) procedure with flap coverage for acute soft tissue defects following total knee arthroplasty: a retrospective study.

Acute soft tissue defects, such as persistent drainage, wound dehiscence, or necrosis, following total knee arthroplasty (TKA) can lead to the devastating complication of deep infection. Typically, when a medium-sized defect is present, a gastrocnemius flap is widely employed for soft tissue reconstruction due to its low morbidity and favourable functional outcomes. When facing this situation, we should consider associating the coverage treatment with a debridement, antibiotics, and implant retention (DAIR) surgery procedure, in order to treat a possible acute infection, even when the diagnosis of infection is not clear.

Adjusting the Crystallization of Tin Perovskites through Thiophene Additives for Improved Photovoltaic Stability.

Tin-based perovskites (Sn-PVK) are promising lead-free alternatives for efficient photovoltaic technology, but they face challenges related to bulk and surface defects due to suboptimal crystallization and Sn oxidation. Introducing thiophene-2-ethylammonium halides (TEAX, where X = I, Br, Cl) improves FASnI crystallization and reduces Sn formation. This is achieved by adjusting the crystallization dynamics through the formation of a complex between S and Sn during the preparation of the precursor solution, which also inhibits Sn oxidation in the resulting films.

Prevalence and Impact of Unexpected Positive Intraoperative Cultures in Total Hip or Knee Revision Surgery.

Background: Our aim was to evaluate the prevalence and impact of unexpected positive intraoperative cultures (UPICs) on the outcome of presumed aseptic total knee and hip revision surgery.

Methods: Data regarding patients who underwent elective total hip or knee revision surgery from January 2003 to July 2017 due to preoperatively presumed aseptic reasons was retrospectively reviewed. Partial revisions and patients who had follow-ups below 60 months were excluded from the study.
