Tar Trap: No Evidence of Domestic Dog Burial with âLa Brea Womanâ
We radiocarbon dated the domestic dog found associated with La Brea Woman at the Rancho La Brea tar pits (Los Angeles, CA) to determine the validity of this humanâdog connection. The domestic dog yielded a radiocarbon age of 3125 ± 25 14C yr BP (3250â3400 cal yr BP) and La Brea Woman had a re-dated age of 9080 ± 15 14C yr BP (10,220â10,250 cal yr BP). This âŒ7000-year offset dispels the hypothesis this was an intentional and ceremonial humanâdog burial
Effect of triclosan-coated sutures on surgical site infections in pilonidal disease: prospective randomized study
Common surgical procedures in pilonidal sinus disease: A meta-analysis, merged data analysis, and comprehensive study on recurrence
Abstract We systematically searched available databases. We reviewed 6,143 studies published from 1833 to 2017. Reports in English, French, German, Italian, and Spanish were considered, as were publications in other languages if definitive treatment and recurrence at specific follow-up times were described in an English abstract. We assessed data in the manner of a meta-analysis of RCTs; further we assessed non-RCTs in the manner of a merged data analysis. In the RCT analysis including 11,730 patients, Limberg & Dufourmentel operations were associated with low recurrence of 0.6% (95%CI 0.3â0.9%) 12 months and 1.8% (95%CI 1.1â2.4%) respectively 24 months postoperatively. Analysing 89,583 patients from RCTs and non-RCTs, the Karydakis & Bascom approaches were associated with recurrence of only 0.2% (95%CI 0.1â0.3%) 12 months and 0.6% (95%CI 0.5â0.8%) 24 months postoperatively. Primary midline closure exhibited long-term recurrence up to 67.9% (95%CI 53.3â82.4%) 240 months post-surgery. For most procedures, only a few RCTs without long term follow up data exist, but substitute data from numerous non-RCTs are available. Recurrence in PSD is highly dependent on surgical procedure and by follow-up time; both must be considered when drawing conclusions regarding the efficacy of a procedure
