The COVID-19 pandemic presented a unique challenge for Medical systems worldwide. Initial response to the crisis situation for the pandemic closely mirrored plans for a mass casualty event. By leveraging resources including human and physical, and by dividing our surgeon workforce into micro teams we were able to create a flexible and responsive infrastructure to address the crisis as it unfolded. By adoption of virtual platforms and equal division of labor, surgical resident education was continued. Specific adjustments to the schedule and curriculum for medical students allowed them to continue their studies safely and on schedule. Our model serves as an example by which hospital systems of similar size may utilize principles of mass casualty preparedness to craft their own plan for a future contagion response strategy.

Background There is an opioid epidemic in the United States. With the increased concern of over-prescribing opioids, physicians are seeking alternative pain management strategies. The purpose of this study is to review the impact of instituting a multimodal analgesia (MMA) guideline on decreasing opioid use in trauma patients at a Level 1 trauma center. Methods In 2017, an MMA guideline was developed and included anti-inflammatories, muscle relaxants, neuropathic agents, and local analgesics in addition to opioids. Staff were educated and the guideline was implemented. A retrospective review of medications prescribed to patients admitted from 2016 through 2018 was performed. Patients admitted in 2016 served as the control group (before MMA). In 2018, all patients received multimodal pain therapy as standard practice, and served as the comparison group. Results A total of 10 340 patients were admitted to the trauma service from 2016 through 2018. There were 3013 and 3249 patients for review in 2016 and 2018, respectively. Total morphine milligram equivalents were 2 402 329 and 1 975 935 in 2016 and 2018, respectively, a 17.7% decrease ( P < .001). Concurrently, there was a statistically significant increase in the use of multimodal pain medications. A secondary endpoint was studied to evaluate for changes in acute kidney injury; there was not a statistically significant increase (0.56% versus 0.68%, P = .55). Discussion Implementation of an MMA guideline significantly reduced opioid use in trauma patients. The use of nonopioid MMA medications increased without an increased incidence of acute kidney injury.

Background Coronavirus patients demonstrate varying degrees of respiratory insufficiency; many will progress to respiratory failure with a severe version of acute respiratory distress syndrome refractory to traditional supportive strategies. Providers must consider alternative therapies to deter or prevent the cascade of decompensation to fulminant respiratory failure. Methods This is a case-series of five COVID-19 positive patients who demonstrated severe hypoxemia, declining respiratory performance, and escalating oxygen requirements. Patients met the following criteria: COVID-19 positivity, worsening respiratory performance, severe hypoxemia (PaO2 ≤ 80) despite traditional supportive measures, escalating supplemental oxygen requirements, and D-dimer greater than 1.5 μg/mL. All patients received protocol directed thrombolytic therapy with tissue plasminogen activator (tPA). Results All five patients improved without deleterious effects of thrombolytic therapy. Patient one was on maximum ventilator support, paralytics, and prone positioning without improvement. During tPA administration his PaO2/FIO2 ratio improved from 69 to 127. Ventilator support was weaned immediately on posttreatment day 1, and he was extubated on posttreatment day 12. Our second through fifth patients were not intubated at time of initiation of tPA therapy. These patients each required significant oxygen supplementation trending toward intubation. After tPA therapy, all patients demonstrated a noticeable increase in PaO2 values overtime. Three of these patients avoided intubation due to COVID-19-associated respiratory failure. Conclusion Administration of thrombolytics was followed by overall improvement in patients' oxygen requirements, and in three cases, prevented progression to mechanical ventilation, without deleterious effects. Clinical trials of thrombolytic therapy would further serve to underscore the efficacy and utility of this therapy. Level of evidence Case series of therapeutic effect, Level V.

Background The practice of utilizing gene expression profile (GEP) for the evaluation and treatment of cutaneous melanomas has been found to predict the risk of sentinel-node metastasis and recurrence. Information obtained from this assay has been used to determine clinical decision-making, including serving as an indication for sentinel lymph node biopsy and also for the intensity of screening measures. Methods Herein we present our early experience in utilizing 31-GEP in intermediate melanomas and its effect on clinical management. A retrospective review was conducted of patients who had undergone treatment for melanoma whose tumors had been subjected to 31-GEP. Additionally, patient characteristics, attributes of the original tumor biopsied, findings on final pathology, and procedures performed were evaluated. Results 31-GEP stratified patients into 4 groups; groups 1A and 1B are considered low risk of metastasis or recurrence, while 2A and 2B are considered high risk. Over the study period, 31-GEP was conducted on 26 cutaneous melanoma patients. Testing and treatment data are available for 23 of these patients. Eleven patients were found to be low risk (9 as 1A, 2 as 1B), 12 were found to be high risk (4 as 2A, 8 as 2B). Decision-making was altered such that sentinel lymph node biopsy was omitted in 2 cases in which the patients were found to be low risk with age >65 years. Discussion In 8 cases of node-negative disease in genetically high-risk patients, surveillance measures were augmented with positron emission tomography/computed tomography. Utilization of 31-GEP is ongoing at our institution.

The effect of mammographic screening on the natural history and evolution of breast cancer treatment cannot be overstated; however, despite intensive and resource consuming screening, advanced breast cancer is still diagnosed frequently. The development of three-dimensional mammography or digital breast tomosynthesis (DBT) has already demonstrated greater sensitivity in the diagnosis of breast pathology and effectiveness in identifying early breast cancers. In addition to being a more sensitive screening tool, other studies indicate DBT has a lower call-back rate when compared with traditional DM. This study compares call-back rates between these two screening tools. A single institution, retrospective review was conducted of almost 20,000 patient records who underwent digital mammography or DBT in the years 2016 to 2018. These charts were analyzed for documentation of imaging type, Breast Imaging Reporting and Data System 0 status, call-back status, and type of further imaging that was required. Charts for 19,863 patients were reviewed, 17,899 digital mammography examinations were conducted compared with 11,331 DBT examinations resulting in 1,066 and 689 Breast Imaging Reporting and Data System 0 studies, respectively. Of the DM call-backs, 82.08 per cent were recommended for additional radiographic imaging and 17.82 per cent for ultrasound imaging. In the DBT group, only 39.77 per cent of call-backs were recommended for additional radiographic imaging and 60.09 per cent for ultrasound imaging. Our data suggest that DBT results in less call-back for additional mammographic images as compared with digital mammography. DBT may offer benefits over DM, including less imaging before biopsy, less time before biopsy, quicker diagnosis, and improved patient satisfaction.

Accelerated partial breast irradiation (APBI) using the implanted brachytherapy device MammoSite® was approved for routine use by the Food and Drug Administration in 2002. The American Society of Breast Surgeons MammoSite® Breast Brachytherapy Registry served as a guideline for our institution to begin offering this treatment in 2005. This report reviews our available data to provide an analysis of patient outcomes over 12 years of use at a single institution. A retrospective review was conducted of records of 150 patients who underwent APBI or attempted APBI after breast-sparing surgeries between 2006 and 2017. These charts were analyzed for documentation of patient age, cancer stage, incidence of recurrence, and posttreatment complications. Of the patients evaluated, 99 per cent (149/150) completed treatment. The median time since treatment completion is now 8.9 years. One hundred eleven patients (74%) are now greater than five years posttreatment. Ipsilateral breast recurrence was found in 2.7 per cent of patients (4/149), and 1.3 per cent of patients (2/149) developed new primary breast tumors. Acute complications, mostly skin erythema (21%), were uncommon and self-limited. Subacute effects were generally fibrosis (13%) and mild local pain (9.4%). APBI for breast cancer after breast-conserving surgery continues to be used at our institution for select patients with good outcomes. Local control and toxicity are similar to that reported in the literature. Five-year local recurrence rates compare favorably with national trials. Occasional complications included fibrosis, persistent pain, and skin irritation.

This is a 10-year retrospective chart review evaluating the potential impact of the most recent American Cancer Society mammography screening guidelines which excludes female patients aged 40 to 44 years from routine annual screening mammography. Instead they recommend screening mammography starting at age 45 with the option to begin screening earlier if the patient desires. The institutional cancer registry was systematically searched to identify all women aged 40 to 44 years treated for breast cancer over a 10-year period. These women were separated into two cohorts: screening mammography detected cancer (SMDC) and nonscreening mammography detected cancer (NSMDC). Statistical analysis of the cohorts was performed for lymph node status (SLN), five-year disease-free survival, and five-year overall survival. Women with SMDC had a significantly lower incidence of SLN positive cancer than the NSMDC group, 9 of 63 (14.3%) versus 36 of 81 (44 %; P < 0.001). The five-year disease-free survival for both groups was 84 per cent for SMDC and 80 per cent for NSMDC; this was not statistically significant. The five-year overall survival was statistically significant at 94 per cent for the SMDC group and 80 per cent for the NSMDC group (P < 0.05). This review demonstrates the significance of mammographic screening for early detection and treatment of breast cancer. Mammographic screening in women aged 40 to 44 detected tumors with fewer nodal metastases, resulting in improved survival and reaffirming the need for annual mammographic screening in this age group.
