Utilization of Topical Polysporin and Triamcinolone for the Treatment of Hypergranulation Tissue.

Hypergranulation is the abnormal accumulation of granulation tissue in a wound and is commonly seen in burns. It impairs wound healing and can predispose patients to infection. There is no gold standard treatment for hypergranulation tissue, but some options include surgical debridement, chemical cautery with silver nitrate, and topical steroids. Silver nitrate treatment is painful and can lead to scarring, so topical steroid use is on the rise. A retrospective review, between January 1, 2017 and August 30, 2021, at a tertiary burn center was performed to analyze outcomes of hypergranulation tissue after treatment with a topical 50/50 mixture of triamcinolone (Perrigo, Dublin, Ireland) and Polysporin (Johnson & Johnson, New Brunswick, NJ). One hundred and sixteen patients were treated with triamcinolone and Polysporin for hypergranulation tissue, although 24 did not meet inclusion criteria. Eighty-eight out of 92 patients were successfully treated until hypergranulation resolution, while 4/92(4.3%) required silver nitrate or surgery despite the topical cream to achieve resolution. In the 88 patients successfully treated until hypergranulation resolution, 99 areas of hypergranulation were treated. Forty-one of 99 (41.4%) hypergranulation areas resolved within 2 weeks. The average time to hypergranulation resolution was 27.5 ± 2.5 days. We found that a novel 50/50 mixture of triamcinolone and Polysporin topical ointment is an effective and safe treatment for hypergranulation tissue in burn wounds. Further prospective studies are needed to determine its efficacy and safety profile.

Risk Factors for Adjacent Segment Disease in Short Segment Lumbar Interbody Fusion-A Case Series.

BACKGROUND: Adjacent segment disease (ASD) is a common problem after lumbar spinal fusions. Ways to reduce the rates of ASD are highly sought after to reduce the need for reoperation. OBJECTIVE: To find predisposing factors of ASD after lumbar interbody fusions, especially in mismatch of pelvic incidence and lumbar lordosis (PI-LL). METHODS: We conducted a retrospective cohort study of all patients undergoing lumbar interbody fusions of less than 4 levels from June 2015 to July 2020 with at least 1 year of follow-up and in those who had obtained postoperative standing X-rays. RESULTS: We found 243 patients who fit inclusion and exclusion criteria. Fourteen patients (5.8%) developed ASD, at a median of 24 months. Postoperative lumbar lordosis was significantly higher in the non-ASD cohort (median 46.4° ± 1.4° vs 36.9° ± 3.6°, P < .001), pelvic tilt was significantly lower in the non-ASD cohort (16.0° ± 0.66° vs 20.3° ± 2.4°, P = .002), PI-LL mismatch was significantly lower in the non-ASD cohort (5.28° ± 1.0° vs 17.1° ± 2.0°, P < .001), and age-appropriate PI-LL mismatch was less common in the non-ASD cohort (34 patients [14.8%] vs 13 [92.9%] of patients with high mismatch, P < .001). Using multivariate analysis, greater PI-LL mismatch was predictive of ASD (95% odds ratio CI = 1.393-2.458, P < .001) and age-appropriate PI-LL mismatch was predictive of ASD (95% odds ratio CI = 10.8-970.4, P < .001). CONCLUSION: Higher PI-LL mismatch, both age-independent and when adjusted for age, after lumbar interbody fusion was predictive for developing ASD. In lumbar degenerative disease, correction of spinopelvic parameters should be a main goal of surgical correction.

Changes in Perioperative Outcomes after Robotic-Assisted Pulmonary Lobectomy during the COVID-19 Era.

Background: The COVID-19 pandemic presented patients with barriers to receiving healthcare. We sought to determine whether changes in healthcare access and practice during the pandemic affected perioperative outcomes after robotic-assisted pulmonary lobectomy (RAPL). Methods: We retrospectively analyzed 721 consecutive patients who underwent RAPL. With March 1st, 2020, defining the start of the COVID-19 pandemic, we grouped 638 patients as "PreCOVID-19" and 83 patients as "COVID-19-Era" based on surgical date. Demographics, comorbidities, tumor characteristics, intraoperative complications, morbidity, and mortality were analyzed. Variables were compared utilizing Student's t-test, Wilcoxon rank-sum test, and Chi-square (or Fisher's exact) test, with significance at p ≤ 0.05 . Multivariable generalized linear regression was used to investigate predictors of postoperative complication. Results: COVID-19-Era patients had significantly higher preoperative FEV1%, lower cumulative smoking history and higher incidences of preoperative atrial fibrillation, peripheral vascular disease (PVD), and bleeding disorders compared to PreCOVID-19 patients. COVID-19-Era patients had lower intraoperative estimated blood loss (EBL), reduced incidence of new-onset postoperative atrial fibrillation (POAF), but higher incidence of effusion or empyema postoperatively. Overall postoperative complication rates between the groups were similar. Older age, increased EBL, lower preoperative FEV1%, and preoperative COPD are all predictive of an increased risk for postoperative complication. Conclusions: COVID-19-Era patients having lower EBL and less new-onset POAF, despite greater incidences of multiple preoperative comorbidities, demonstrates that RAPL is safe during the COVID-19 era. Risk factors for development of postoperative effusion should be determined to minimize risk of empyema in COVID-19-Era patients. Age, preoperative FEV1%, COPD, and EBL should all be considered when planning for complication risk.

A High Preoperative Blood Urea Nitrogen to Serum Albumin Ratio Does Not Predict Worse Outcomes Following the Robotic-Assisted Pulmonary Lobectomy for Lung Cancer.

BACKGROUND:  The blood urea nitrogen to serum albumin ratio (BAR) is an emerging prognostic parameter of interest. The utility of BAR as a prognostic factor has not been analyzed in lung cancer patients undergoing pulmonary lobectomy. We evaluated the ability of High BAR to predict worse outcomes after robotic-assisted pulmonary lobectomy (RAPL) for lung cancer. METHODS:  We retrospectively analyzed 400 patients who underwent RAPL from September 2010 to March 2022 by one surgeon. Patients were stratified by Low BAR (<6.25 mg/g) and High BAR (≥6.25 mg/g). Patients' demographics, tumor characteristics, comorbidities, surgical complications, outcomes, and survival were collected and compared by High and Low BAR groups. The primary outcome of interest was 30-day mortality. RESULTS:  Receiver operator curves (ROC) confirmed that 6.25 was an optimal threshold for estimating mortality based on Low and High BAR. There were no differences in surgical complications or outcomes between the Low and High BAR groups. The ability of BAR to predict 30-day mortality was evaluated with the area under the curve (AUC) analysis, which showed that higher BAR could not predict mortality (AUC=0.655; 95% CI, 0.435-0.875; p=0.166). Similarly, survival analysis revealed no difference in five-year overall survival between the Low and High BAR groups (p=0.079). CONCLUSION:  High BAR did not predict worse outcomes after RAPL for lung cancer in our study. Further studies are needed to better determine the prognostic ability of BAR in lower-risk populations.
