Background Deep, high-grade bursal-sided supraspinatus tendon tears are sometimes preoperatively misinterpreted as full-thickness tears on shoulder magnetic resonance imaging (MRI). Purpose To determine the usefulness of disproportionate fluid sign for differentiating high-grade bursal-sided partial-thickness tears from full-thickness tears on conventional MRI. Material and Methods Preoperative MRIs of 198 patients with arthroscopically confirmed high-grade bursal-sided partial-thickness tears and full-thickness tears were independently reviewed by two readers on two occasions. The presence of high-grade bursal-sided partial-thickness tears with a confidence level using a five-point grading scale was assessed based on tear depth alone and also in combination with disproportionate fluid sign, defined as a prominent subdeltoid or subacromial-subdeltoid bursal fluid distension with a relative paucity of effusion in the glenohumeral joint. The sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve (AUC) were calculated, as well as inter-observer reliability. Results The disproportionate fluid sign was identified in 60/74 (81.2%) bursal-sided partial-thickness tears and 9/124 (7.5%) full-thickness tears. The sensitivity and accuracy of the diagnosis of bursal-sided tear were higher when disproportionate fluid sign was used in conjunction with the tear depth, compared with tear depth alone ( P < 0.001). There was excellent inter-observer agreement for disproportionate fluid sign and deep bursal-sided tear. The AUCs were significantly higher in combination with disproportionate fluid sign. Conclusion The disproportionate fluid sign indicates the presence of a deep, high-grade bursal-sided partial-thickness tear, which can be misinterpreted as a full-thickness tear. Thus, it can provide greater diagnostic assistance to less-experienced radiologists and clinicians.

Abstract Background Objectives: To comparatively evaluate the role of ultrasound and MRI in rotator cuff and biceps tendon pathologies and to establish ultrasound as a consistently reproducible, quick and accurate primary investigation modality sufficient to triage patients requiring surgical correction of full thickness rotator cuff tears. Methods: Fifty patients, clinically suspected to have rotator cuff and/or biceps tendon pathologies, with no contraindications to MRI, were evaluated by US and MRI, in a prospective cross-sectional observational study. US was done with high-frequency linear probe, and MRI was done on a 1.5-T scanner using T1 oblique sagittal, proton density (PD)/T2 fat-suppressed (FS) oblique sagittal, T1 axial, PD/T2 FS axial, T1 oblique coronal, T2 oblique coronal and PD FS oblique coronal sequences. Statistical testing was conducted with the statistical package for the social science system version SPSS 17.0. The sensitivity, specificity, PPV, NPV and accuracy were also calculated to analyze the diagnostic accuracy of US findings correlating with MRI findings. A p value less than 0.05 was taken to indicate a significant difference. Results Mean age was 45 years; 74% patients were males; 77% females and 60% males had tears. Majority of patients with rotator cuff tears were in the sixth decade of life. The frequency of tears was higher among older patients. Fourteen percent of patients had full thickness tears while 64% had partial thickness tears. US was comparable to MRI for detection of full thickness tears with overall sensitivity, specificity, PPV and accuracy of 93.8%, 100%, 100% and 98.2%, respectively (p value < 0.001). For partial thickness tears, US had overall sensitivity, specificity, PPV and accuracy of 75.6%, 82.6%, 89.5% and 78%, respectively (p value < 0.001), as compared to MRI. Subacromial-subdeltoid bursal effusion and long head of biceps tendon sheath effusion were common associated, though, non-specific findings. Conclusion Ultrasound findings in our study were found to be in significant correlation with findings on MRI in detection of rotator cuff tears. US was equivalent to MRI in detection of full thickness tears and fairly accurate for partial thickness tears. Therefore, US should be considered as the first line of investigation for rotator cuff pathologies.

Abstract Objective Burn wound progression is an inflammation driven process where an initial partial-thickness thermal burn wound can evolve over time to a full-thickness injury. We have developed an oil-in-water nanoemulsion formulation (NB-201) containing benzalkonium chloride for use in burn wounds that is antimicrobial and potentially inhibits burn wound progression. We used a porcine burn injury model to evaluate the effect of topical nanoemulsion treatment on burn wound conversion and healing. Methods Anesthetized swine received thermal burn wounds using a 25cm 2 surface area copper bar heated to 80 oC. Three different concentrations of NB-201 (10%, 20%, or 40% nanoemulsion), silver sulfadiazine cream or saline were applied to burned skin immediately after injury and on days 1, 2, 4, 7, 10, 14, and 18 post-injury. Digital images and skin biopsies were taken at each dressing change. Skin biopsy samples were stained for histological evaluation and graded. Skin tissue samples were also assayed for mediators of inflammation. Results Dermal treatment with NB-201 diminished thermal burn wound conversion to a full-thickness injury as determined by both histological and visual evaluation. Comparison of epithelial restoration on day 21 showed that 77.8% of the nanoemulsion treated wounds had an epidermal injury score of 0 compared to 16.7% of the silver sulfadiazine treated burns (p=0.01). Silver sulfadiazine cream and saline treated wounds (controls) converted to full-thickness burns by day 4. Histological evaluation revealed reduced inflammation and evidence of skin injury in NB-201 treated sites compared to control wounds. The nanoemulsion treated wounds often healed with complete regrowth of epithelium and no loss of hair follicles (NB-201: 4.8±2.1, saline: 0±0, silver sulfadiazine: 0±0 hair follicles per 4mm biopsy section, p&lt;0.05). Production of inflammatory mediators and sequestration of neutrophils were also inhibited by NB-201. Conclusions Topically applied NB-201 prevented the progression of a partial-thickness burn wound to full-thickness injury and was associated with a concurrent decrease in dermal inflammation.

Partial Thickness Burns

Abstract Burns to the face affect a part of the body that cannot be hidden and thus exposes potentially major changes in appearance to society. Therefore, it is incumbent upon the caregiver to optimize healing and minimize scarring. The goal for partial-thickness burns is to have them heal within 2–3 weeks to minimize healing time. For full-thickness burns there needs to be strategies to optimize the outcomes for skin grafting and minimize scarring. The goal of this review is to discuss the best way to improve the outcomes of these devastating injuries.

Hand Burns

We studied the efficacy of the glove-gauze regimen in treating superficial, partial-thickness and small full-thickness hand burns. Outcome measures included healing time, need for surgical intervention, need for formal physical therapy, restoration of range of motion, return to function and incidence of infection. All patients ( n = 123) successfully completed the regimen with an average healing time of 3.7 weeks. None required surgical debridement and seven (6%) required formal physical therapy. One hundred and eighteen patients (96%) regained full range of motion and 122 (99%) returned to their previous level of work. We believe that the glove-gauze regimen provides a simplified and effective means of managing hand burns. We conclude from our patients that the glove-gauze regimen is an effective treatment that can ensure uneventful healing of superficial, partial-thickness and small full-thickness burns. A majority of our patients healed with full range of motion and function without formal physical therapy. Level of evidence: IV

Dressing Change

Abstract Introduction Postoperative dressing and wound care are essential to optimize graft survival through imbibition, inosculation, and neovascularization. Autologous skin cell suspension (ASCS) using extended-wear dressings (EWD) as a primary or secondary has not been previously described in the literature. The goal of our study was to assess the feasibility of new dressing protocol for ASCS at reducing dressing changes without increasing reoperation rates for failure to close or mortality. Methods The study was an IRB approved, single-center, retrospective review of admissions between April 2018 to August 2019. Patients included in the study were &gt;14 years of age with &gt;3%TBSA partial-thickness and full-thickness burns undergoing excision and ASCS. EWD included a controlled-release silver antimicrobial dressing with active fluid management. Standard of Care (SoC) primary dressing with fine-pore, non-adherent polyethylene film followed by petroleum gauze, layered gauze, and compressive dressings. Data included age, gender, %TBSA, mortality, primary and secondary dressing, dressings changes prior to primary dressing change (DC), and failure to close (FTC) requiring reoperation. Fisher’s exact test was used to compare the two populations. Results A total of 53 ASCS cases were performed with 33 receiving standard of care (SOC) and 20 EWD post-operatively. The median age was 48 (range 14–85) with 26% of the patients being female. The median TBSA was 17% (range 3–72%). Median age for SoC was 57 and for EWD was 33 (p-value= 0.0289). Median %TBSA for SoC was 20% and for EWD was 15% (p-value= 0.0182). 1 SoC patient required reoperation from both groups (p-value= 0.5210). No EWD patients required reoperation. 1 patient expired (SoC) in the study secondary to decompensated cirrhosis. EWD required median 1 DC versus 3 in the SoC group (p-value= 0.0164). Conclusions EWD with ASCS reduced the total number of dressing changes and did not result in increased mortality or reoperation for FTC in our feasibility trial with partial-thickness and full-thickness burn injuries. Optimizing postoperative care with EWD in ASCS may serve to reduce dressing change costs and patient discomfort as well as to shorten hospital length of stay. Applicability of Research to Practice Reduced wound care following autologous skin cell suspension.
