RESUMO
OBJECTIVE: Identify the frequency and types of mistreatment experienced by residents from patients and their families (P&F) and determine whether the types and frequency varied based on resident gender. DESIGN: An anonymous survey was distributed to residents to assess the types of P&F mistreatment toward residents and the association with resident gender. SETTING: The survey was distributed to the general surgery and urology programs at a large academic medical center in the mid-Atlantic. Participants: 23 of 53 residents (43% response rate) participated in the anonymous survey. Residents: 15 male residents (65%), 8 female residents (35%). Results: 12 of 23 responding residents (52%) indicated they experienced at least one form of mistreatment from P&F. Women were more likely to experience mistreatment (88% vs. 33%), with verbal assault was the most frequent (50% for female residents, 33% for male residents). Patients were more often the source than families (52% vs. 41%); verbal assault or threats of physical harm were the most common (50% for female residents, 33% for male residents). CONCLUSIONS: Residents experience mistreatment from multiple sources. This paper provides insight into the experiences of surgical residents with mistreatment from their P&F, with differences in frequency of behaviors dependent upon the perpetrator group and resident gender. Patients and their family mistreatments are likely underreported and may be more difficult to prevent. It is important to identify mitigation strategies and ensure resources are available for those residents experiencing mistreatment. A strong culture against mistreatment and providing specific resources may minimize the experience and negative effects of mistreatment.

Importance: Various surgical approaches for hidradenitis suppurativa (HS) have been described in the literature, but the nomenclature is inconsistent. Excisions have been described as wide, local, radical, and regional with variable descriptions of margins. Deroofing procedures have been described with various approaches though descriptions of the approach are generally more uniform. No international consensus has been formed to globally standardize terminology for HS surgical procedures. Lack of such agreement may contribute to misunderstanding or misclassification in HS procedural research studies and impair clear communication among clinicians or between clinicians and patients. Objective: To create a set of standard definitions for HS surgical procedures. Design, Setting, and Participants: This consensus agreement study was conducted from January to May 2021 using the modified Delphi consensus method to reach agreement among a group of international HS experts regarding standardized definitions for an initial set of HS surgical terms, including "incision and drainage," "deroofing/unroofing," "excision," "lesional excision," and "regional excision," ultimately expanded to 10 terms. Provisional definitions were drafted based on existing literature and discussion among an expert 8-member steering committee. Online surveys were disseminated to members of the HS Foundation, direct contacts of the expert panel, and the HSPlace listserv to reach physicians with considerable experience with HS surgery. Consensus was defined as greater than 70% agreement to accept a definition. Results: In the first and second modified Delphi round, 50 and 33 experts participated, respectively. Ten surgical procedural terms and definitions reached consensus with greater than 80% agreement. Overall, the term "local" excision was abandoned and replaced with the descriptors "lesional" or "regional" excision. Of note, "regional" replaced the terms "wide" and "radical" excision. Furthermore, modifiers such as "partial" vs "complete" should also be included when describing surgical procedures. A combination of these terms helped formulate the final glossary of HS surgical procedural definitions. Conclusion and Relevance: An international group of HS experts agreed on a set of definitions describing surgical procedures frequently used by clinicians and in the literature. The standardization and application of such definitions are vital to allow for accurate communication, reporting consistency, and uniform data collection and study design in the future.

BACKGROUND: Hidradenitis suppurativa (HS) is a debilitating inflammatory skin disease characterized by painful nodules, drainage and scarring in skin folds. Injectable adalimumab is the only drug approved by the US Food and Drug Administration for the treatment of HS. Although systemic Janus kinase (JAK) inhibitors show promise, serious side-effects have been reported. There are no highly effective topical treatments for HS; furthermore, the contribution of epidermal keratinocytes to the intense inflammation has largely been unexplored. OBJECTIVES: We investigated the role of keratinocytes and epidermal immune cells in HS inflammation at all Hurley stages of disease severity. We aimed to determine whether ruxolitinib can mitigate inflammation from keratinocytes and to develop a better understanding of how topical therapeutics might benefit patients with HS. METHODS: We used skin samples from 87 patients with HS (Hurley stages I-III) and 39 healthy controls to compare keratinocyte- and immune cell-driven epidermal inflammation, in addition to the response of lesional HS keratinocytes to treatment with interferon (IFN)-γ and ruxolitinib. We used haematoxylin and eosin staining, immunohistochemistry, immunoblotting and quantitative reverse-transcription polymerase chain reaction assessments in whole skin, isolated epidermis, and cultured keratinocytes from healthy controls and both nonlesional and lesional HS skin to identify and define epidermal and keratinocyte-mediated inflammation in HS and how this may be targeted by therapeutics. RESULTS: HS lesional keratinocytes autonomously secreted high levels of chemokines, such as CCL2, CCL3 and CXCL3, which recruited neutrophils, CD8 T cells, and natural killer cells to the epidermis. Keratinocytes were the dominant source of tumour necrosis factor-α and interleukin (IL)-6 in HS lesions with little to no contribution from underlying dermal immune cells. In the presence of IFN-γ, which is dependent on immune cell infiltrate in vivo, keratinocytes expressed increased levels of additional cytokines including IL-1ß, IL-12, IL-23 and IL-36γ. The JAK inhibitor ruxolitinib mitigated the expression of inflammatory cytokines and chemokines in HS lesional keratinocytes, thus providing a rationale for future study as a topical treatment for HS. CONCLUSIONS: This study demonstrates that keratinocytes actively recruit immune cells to HS epidermis and interactions between these cells drive a broad inflammatory profile in HS epidermis. Targeting epidermal inflammation in HS with novel topical formulations may be highly efficacious with reduced systemic side-effects.

BACKGROUND: Medication management, a complex yet essential part of patient care, requires that clinicians and patients understand indication, dosage, frequency, and adverse effects in order to maximize benefits and minimize errors, as well as to transition patients from hospital to home. Clinical pharmacists improve care transitions and safety by interacting with patients, prescribers, and nurses on medication management and self-care. However, little is known on the use of clinical pharmacists on interdisciplinary teams at the unit level within orthopedics. QUESTIONS/PURPOSES: This study sought to measure the impact of unit-based clinical pharmacists on patient perceptions of communication specific to medication during hospitalization at an orthopedic specialty hospital and on the frequency of medication errors. METHODS: A retrospective, quasi-experimental, two-group evaluative design with nonequivalent controls was used. Consumer Assessment of Healthcare Providers and Systems (HCAHPS) data on six inpatient units was analyzed 6 months before and 6 months after assignment of clinical pharmacists to half these units. Data specific to questions that measure quality of communication as well as medication understanding were analyzed. Additionally, data on medication error frequency were collected and compared between units with and without clinical pharmacists. RESULTS: A total of 2022 surveys were analyzed. The percentage of patients who reported receipt of medication information and medication understanding increased significantly after the implementation of unit-based clinical pharmacists. Comparison of intervention and non-intervention groups showed no statistically significant difference in the frequency of medication errors. CONCLUSION: Results suggest that a clinical pharmacist assigned to an inpatient unit in orthopedics significantly influences patient perceptions of communication about and understanding of their medications.
RESUMO
BACKGROUND: Mistreatment has been correlated with burnout and poor well-being in medical students, but data regarding residents and faculty are limited. The objective was to investigate the prevalence of mistreatment towards surgical housestaff and faculty and characterize such experiences. METHODS: In 2018, the Department of Surgery surveyed housestaff and faculty on incidents of mistreatment. RESULTS: Clinical faculty (63%) and residents (72%) completed the mistreatment survey. Excluding public embarrassment, 48% of residents and 29% of clinical faculty experienced mistreatment. Residents experienced public embarrassment and public humiliation more frequently than faculty, however faculty were subjected to racially or ethnically offensive remarks/names more frequently than residents (p < .05). Faculty within and external to their department were most cited as instigators of mistreatment. Residents experienced mistreatment most often by faculty, co-residents, and nurses. Reporting of the behaviors was low. CONCLUSIONS: Incidents of mistreatment are frequently occurring for surgical residents and faculty.

BACKGROUND: Accurate medication reconciliation in trauma patients is essential but difficult. Currently, there is no established clinical method of detecting direct oral anticoagulants (DOACs) in trauma patients. We hypothesized that a liquid chromatography-mass spectrometry (LCMS)-based assay can be used to accurately detect DOACs in trauma patients upon hospital arrival. METHODS: Plasma samples were collected from 356 patients who provided informed consent including 10 healthy controls, 19 known positive or negative controls, and 327 trauma patients older than 65 years who were evaluated at our large, urban level 1 trauma center. The assay methodology was developed in healthy and known controls to detect apixaban, rivaroxaban, and dabigatran using LCMS and then applied to 327 samples from trauma patients. Standard medication reconciliation processes in the electronic medical record documenting DOAC usage were compared with LCMS results to determine overall accuracy, sensitivity, specificity, and positive and negative predictive values (PPV, NPV) of the assay. RESULTS: Of 356 patients, 39 (10.96%) were on DOACs: 21 were on apixaban, 14 on rivaroxaban, and 4 on dabigatran. The overall accuracy of the assay for detecting any DOAC was 98.60%, with a sensitivity of 94.87% and specificity of 99.05% (PPV, 92.50%; NPV, 99.37%). The assay detected apixaban with a sensitivity of 90.48% and specificity of 99.10% (PPV, 86.36%; NPV 99.40%). There were three false-positive results and two false-negative LCMS results for apixaban. Dabigatran and rivaroxaban were detected with 100% sensitivity and specificity. CONCLUSION: This LCMS-based assay was highly accurate in detecting DOACs in trauma patients. Further studies need to confirm the clinical efficacy of this LCMS assay and its value for medication reconciliation in trauma patients. LEVEL OF EVIDENCE: Diagnostic Test, level III.

Background: Medication errors account for the most common adverse events and a significant cause of mortality in the USA. The Joint Commission has required medication reconciliation since 2006. We aimed to survey the literature and determine the challenges and effectiveness of medication reconciliation in the trauma patient population. Materials and methods: We conducted a systematic review of the literature to determine the effectiveness of medication reconciliation in trauma patients. English language articles were retrieved from PubMed/Medline, CINAHL, and Cochrane Review databases with search terms "trauma OR injury, AND medication reconciliation OR med rec OR med rek, AND effectiveness OR errors OR intervention OR improvements." Results: The search resulted in 82 articles. After screening for relevance and duplicates, the 43 remaining were further reviewed, and only four articles, which presented results on medication reconciliation in 3041 trauma patients, were included. Two were retrospective and two were prospective. Two showed only 4% accuracy at time of admission with 48% of medication reconciliations having at least one medication discrepancy. There were major differences across the studies prohibiting comparative statistical analysis. Conclusions: Trauma medication reconciliation is important because of the potential for adverse outcomes given the emergent nature of the illness. The few articles published at this time on medication reconciliation in trauma suggest poor accuracy. Numerous strategies have been implemented in general medicine to improve its accuracy, but these have not yet been studied in trauma. This topic is an important but unrecognized area of research in this field.

BACKGROUND: The management of penetrating colon injuries in civilians has evolved over the last four decades. The objectives of this meta-analysis are to evaluate the current treatment regimens available for penetrating colon injuries and assess the role of anastomosis in damage control surgery to develop a practice management guideline for surgeons. METHODS: Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, a subcommittee of the Practice Management Guidelines section of EAST conducted a systematic review using MEDLINE and EMBASE articles from 1980 through 2017. We developed three relevant problem, intervention, comparison, and outcome (PICO) questions regarding penetrating colon injuries. Outcomes of interest included mortality and infectious abdominal complications. RESULTS: Thirty-seven studies were identified for analysis, of which 16 met criteria for quantitative meta-analysis and included 705 patients considered low-risk in six prospective randomized studies. Seven hundred thirty-eight patients in 10 studies undergoing damage control laparotomy and repair or resection and anastomosis (R&A) were included in a separate meta-analysis. Meta-analysis of high-risk patients undergoing repair or R&A was not feasible due to inadequate data. CONCLUSIONS: In adult civilian patients sustaining penetrating colon injury without signs of shock, significant hemorrhage, severe contamination, or delay to surgical intervention we recommend that colon repair or R&A be performed rather than routine colostomy. In adult high-risk civilian trauma patients sustaining penetrating colon injury, we conditionally recommend that colon repair or R&A be performed rather than routine colostomy. In adult civilian trauma patients sustaining penetrating colon injury who had damage control laparotomy, we conditionally recommend that routine colostomy not be performed; instead, definitive repair or delayed R&A or anastomosis at initial operation should be performed rather than routine colostomy. LEVEL OF EVIDENCE: Systematic review/meta-analysis, level III.

BACKGROUND: Over 50,000 homicides and suicides occur each year. An estimated half of all US households are believed to have a firearm present, making them one of the most ubiquitous consumer products. Our goal was to determine if the manner of storage of a firearm in a home could potentially make a difference in the outcomes of intentional and unintentional injuries involving a firearm; specifically addressing the use of gun safes and devices that block/disable firearm function (trigger locks, cable locks, etc.). METHODS: A comprehensive review of the literature was performed. We used Grading of Recommendations Assessment, Development, and Evaluation methodology to assess the breadth and quality of the data specific to our Population, Intervention, Comparator, Outcomes (PICO) questions. RESULTS: A total of 176 studies were initially identified, then, 120 more added after a subsequent literature review, with 97 removed as duplicates. One hundred ninety-one case reports, case series, and reviews were removed because they did not focus on prevention or did not address our comparators of interest. This left a total of two studies which merited inclusion for PICO 1, should gun locks be used to prevent firearm injuries and six studies which merited inclusion for PICO 2, should safe storage for guns be used to prevent firearm injuries. CONCLUSION: PICO 1: We conditionally recommend that gun locks be used to prevent unintentional firearm injury. PICO 2: Because of the large effect size and the reasonable quality of available evidence with safe storage of firearms, we recommend safe storage prevent firearm-related injuries. LEVEL OF EVIDENCE: Systematic review, level III.

BACKGROUND: In the past decade, more than 300,000 people in the United States have died from firearm injuries. Our goal was to assess the effectiveness of two particular prevention strategies, restrictive licensing of firearms and concealed carry laws, on firearm-related injuries in the US Restrictive Licensing was defined to include denials of ownership for various offenses, such as performing background checks for domestic violence and felony convictions. Concealed carry laws allow licensed individuals to carry concealed weapons. METHODS: A comprehensive review of the literature was performed. We used Grading of Recommendations Assessment, Development, and Evaluation methodology to assess the breadth and quality of the data specific to our Population, Intervention, Comparator, Outcomes (PICO) questions. RESULTS: A total of 4673 studies were initially identified, then seven more added after two subsequent, additional literature reviews. Of these, 3,623 remained after removing duplicates; 225 case reports, case series, and reviews were excluded, and 3,379 studies were removed because they did not focus on prevention or did not address our comparators of interest. This left a total of 14 studies which merited inclusion for PICO 1 and 13 studies which merited inclusion for PICO 2. CONCLUSION: PICO 1: We recommend the use of restrictive licensing to reduce firearm-related injuries.PICO 2: We recommend against the use of concealed carry laws to reduce firearm-related injuries.This committee found an association between more restrictive licensing and lower firearm injury rates. All 14 studies were population-based, longitudinal, used modeling to control for covariates, and 11 of the 14 were multi-state. Twelve of the studies reported reductions in firearm injuries, from 7% to 40%. We found no consistent effect of concealed carry laws. Of note, the varied quality of the available data demonstrates a significant information gap, and this committee recommends that we as a society foster a nurturing and encouraging environment that can strengthen future evidence based guidelines. LEVEL OF EVIDENCE: Systematic review, level III.

BACKGROUND: Venous Thrombo-embolism (VTE--Deep venous thrombosis (DVT) and/or pulmonary embolism (PE)--in traumatized patients causes significant morbidity and mortality. The current study evaluates the effectiveness of DVT surveillance in reducing PE, and performs a cost-effectiveness analysis. METHODS: All traumatized patients admitted to the adult ICU underwent twice weekly DVT surveillance by bilateral lower extremity venous Duplex examination (48-month surveillance period--SP). The rates of DVT and PE were recorded and compared to the rates observed in the 36-month pre-surveillance period (PSP). All patients in both periods received mechanical and pharmacologic prophylaxis unless contraindicated. Total costs--diagnostic, therapeutic and surveillance--for both periods were recorded and the incremental cost for each Quality Adjusted Life Year (QALY) gained was calculated. RESULTS: 4234 patients were eligible (PSP--1422 and SP--2812). Rate of DVT in SP (2.8%) was significantly higher than in PSP (1.3%) - p<0.05, and rate of PE in SP (0.7%) was significantly lower than that in PSP (1.5%) - p<0.05. Logistic regression demonstrated that surveillance was an independent predictor of increased DVT detection (OR: 2.53 - CI: 1.462-4.378) and decreased PE incidence (OR: 0.487 - CI: 0.262-0.904). The incremental cost was $509,091/life saved in the base case, translating to $29,102/QALY gained. A sensitivity analysis over four of the parameters used in the model indicated that the incremental cost ranged from $18,661 to $48,821/QALY gained. CONCLUSIONS: Surveillance of traumatized ICU patients increases DVT detection and reduces PE incidence. Costs in terms of QALY gained compares favorably with other interventions accepted by society.

BACKGROUND: Early (<8 hours) operative debridement and irrigation (D&I) of open fractures are considered essential to reduce the risk of deep infection. With the advent of powerful antimicrobials, this axiom has been challenged. The current study evaluates the rates of deep infections of open fractures in relation to the time to the first D&I. METHODS: A list of all blunt open fractures during a 6-year period was obtained from the trauma registry. Patients were evaluated for age, Injury Severity Score (ISS), physiologic derangement (systolic blood pressure, lactate, Revised Trauma Score [RTS]), and fracture type (Gustilo). Time to the first D&I was calculated. All patients received appropriate prophylactic antimicrobials. Infection rates were calculated and correlated to the time to the first D&I (<8 hours vs. >8 hours). Regression analysis was performed to identify independent predictors of infection. RESULTS: During the 72-month study period, 404 patients met entry criteria, with 415 open extremity fractures (upper, 129; lower, 287). Early (<8 hours) and delayed (>8 hours) groups were well matched, although the age was lower and ISS was higher in the group with greater than 8 hours. The rates of infection were 35 (11%) of 328 (<8 hour) and 17 (19%) of 87 (>8 hours) (p < 0.05). When fractures were subgrouped by extremity, for the lower extremity, both a delay of greater than 8 hours and higher Gustilo type correlated with the development of infection. In the upper extremity, only higher Gustilo type correlated, and a delay to the first D&I did not increase the incidence of infection. Regression analysis revealed that higher ISS (odd ratio [OR], 1.052; 95% confidence interval [CI], 1.019-1.086), Gustilo grade, and a delay of greater than 8 hours (OR, 2.035; 95% CI, 1.022-4.054) were independent predictors of infection for the all-extremity model. Separate models for upper and lower extremities showed that the same three parameters were independent predictors for the lower extremity (ISS: OR, 1.045; 95% CI, 1.004-1.087; Gustilo type and >8-hour delay: OR, 3.006; 95% CI, 1.280-7.059), but none for the upper extremity. CONCLUSION: Delay of greater than 8 hours to the first D&I for open fractures of the lower extremity increases the likelihood of infection but not for the upper extremity. Higher Gustilo type open fractures have a higher incidence of infection for both upper and lower extremities. The results have important implications in an era of decreasing surgeon availability, especially in off hours. LEVEL OF EVIDENCE: Therapeutic study, level IV.

BACKGROUND: We hypothesize that limited transthoracic echocardiogram (LTTE) is a useful tool to guide therapy during the initial phase of resuscitation in trauma patients. METHODS: All highest-level alert patients with at least one measurement of systolic blood pressure less than 100 mm Hg, a mean arterial pressure less than 60 mm Hg, and/or a heart rate greater than 120 beats per minute who arrived to the trauma bay (TB) were randomized to have either LTTE performed (LTTEp) or not performed (non-LTTE) as part of their initial evaluation. Images were stored, and results were reported regarding contractility (good vs. poor), fluid status (empty inferior vena cava [hypovolemic] vs. full inferior vena cava [not hypovolemic]), and pericardial effusion (present vs. absent). Time from TB to operating room, intravenous fluid administration, blood product requirement, intensive care unit admission, and mortality were examined in both groups. RESULTS: A total of 240 patients were randomized. Twenty-five patients were excluded since they died upon arrival to the TB, leaving 215 patients in the study. Ninety-two patients were in the LTTEp group with 123 patients in the non-LTTE group. The LTTEp and non-LTTE groups were similar in age (38 years vs. 38.8 years, p = 0.75), Injury Severity Score (ISS) (19.2 vs. 19.0, p = 0.94), Revised Trauma Score (RTS) (5.5 vs. 6.0, p = 0.09), lactate (4.2 vs. 3.6, p = 0.14), and mechanism of injury (p = 0.44). Strikingly, LTTEp had significantly less intravenous fluid than non-LTTE patients (1.5 L vs. 2.5 L, p < 0.0001), less time from TB to operating room (35.6 minutes vs. 79.1 min, p = 0.0006), higher rate of intensive care unit admission (80.4% vs. 67.2%, p = 0.04), and a lower mortality rate (11% vs. 19.5%, p = 0.09). Mortality differences were particularly evident in the traumatic brain injury patients (14.7% in LTTEp vs. 39.5% in non-LTTE, p = 0.03). CONCLUSION: LTTE is a useful guide for therapy in hypotensive trauma patients during the early phase of resuscitation. LEVEL OF EVIDENCE: Therapeutic study, level II.

BACKGROUND: The use of prophylactic antibiotics in penetrating abdominal trauma has resulted in decreased infection rates. The Eastern Association for the Surgery of Trauma (EAST) first published its practice management guidelines (PMGs) for the use of prophylactic antibiotics in penetrating abdominal trauma in 1998. During the next decade, several new prospective studies were published on this topic. In addition, the practice of damage control laparotomy became widely used, and additional questions arose as to the role of prophylactic antibiotics in this setting. Thus, the EAST Practice Management Guidelines Committee set out to update the original PMG. METHODS: A search of the National Library of Medicine and the National Institutes of Health MEDLINE databases was performed using PubMed (www.pubmed.gov) and specific key words. The search retrieved English language articles regarding the use of antibiotics in penetrating abdominal trauma published from 1973 to 2011. The topics investigated were the need for perioperative antibiotics, the duration of antibiotic therapy, the dose of antibiotics in patients presenting in hemorrhagic shock, and the appropriate duration of antibiotic therapy in the setting of damage control laparotomy. RESULTS: Forty-four articles were identified for inclusion in this review. CONCLUSION: There is evidence to support a Level I recommendation that prophylactic antibiotics should only be administered for 24 hours in the presence of a hollow viscus injury. In addition, there are no data to support continuing prophylactic antibiotics longer than 24 hours in damage control laparotomy.

BACKGROUND: Health care-associated infections (HAI) result in 100,000 deaths/year. Alcohol use disorders (AUD) increase the risk of community-acquired infections and HAI. Small studies have shown that AUD increase the risk of HAI and surgical site infections (SSI). We sought to determine the risk of HAI and SSI in surgical patients undergoing elective inpatient joint replacement, coronary artery bypass grafting, laparoscopic cholecystectomy, colectomy, and hernia repair. STUDY DESIGN: The Nationwide Inpatient Sample was analyzed (years 2007 and 2008). HAI were defined as health care-associated pneumonia, sepsis, SSI, and urinary tract infection. Primary outcomes were risk of HAI and SSI in patients with AUD. Secondary outcomes were mortality and hospital length of stay in patients with HAI and SSI, alpha = 10(-6). RESULTS: There were 1,275,034 inpatient admissions analyzed; 38,335 (3.0%) cases of HAI were documented, and 5,756 (0.5%) cases of SSI were identified. AUD was diagnosed in 11,640 (0.9%) of cases. Multivariable analysis demonstrated that AUD was an independent predictor of developing HAI: odds ratio (OR) 1.70, p < 10(-6), and this risk was independent of type of surgery. By multivariable analysis, the risk of SSI in patients with AUD was also higher: OR 2.73, p < 10(-6). Hospital mortality in patients with HAI or SSI was not affected by AUD. However, hospital length of stay was longer in patients with HAI who had AUD (multivariable analysis 2.4 days longer, p < 10(-6)). Among patients with SSI, those with AUD did not have longer hospital length of stay. CONCLUSIONS: Patients with AUD who undergo a variety of elective operations have an increased risk of infectious postoperative morbidity.

Modulation of Rho GTPases Rac1 and Rac2 impacts bone development, remodeling, and disease. In addition, GTPases are considered treatment targets for dysplastic and erosive bone diseases including Neurofibromatosis type 1. While it is important to understand the effects of Rac modulation on osteoclast function, two-dimensional resorption pit area measurements fall short in elucidating the volume aspect of bone resorption activity. Bone marrow from wild-type, Rac1 and Rac2 null mice was isolated from femora. Osteoclastogenesis was induced by adding M-CSF and RANKL in culture plates containing dentin slices and later stained with Picro Sirius Red to image resorption lacunae. Osteoclasts were also plated on glass cover slips and stained with phalloidin and DAPI to measure their surface area and the number of nuclei. Volumetric images were collected on a laser-scanning confocal system. Sirius Red confocal imaging provided an unambiguous, continuous definition of the pit boundary compared to reflected and transmitted light imaging. Rac1- and Rac2-deficient osteoclasts had fewer nuclei in comparison to wild-type counterparts. Rac1-deficient osteoclasts showed reduced resorption pit volume and surface area. Lacunae made by single Rac2 null osteoclasts had reduced volume but surprisingly surface area was unaffected. Surface area measures are deceiving since volume changed independently in resorption pits made by individual Rac2 null osteoclasts. Our innovative confocal imaging technique allows us to derive novel conclusions about Rac1 and Rac2 in osteoclast function. The data and method can be applied to study effects of genes and drugs including Rho GTPase modulators on osteoclast function and to develop pharmacotherapeutics to treat bone lytic disorders.

Diffuse dermal angiomatosis is a rare disorder, considered to be a variant of reactive cutaneous angioendotheliomatosis. The patients commonly present with severe intractable breast pain and characteristic reticular violaceous erythematous plaques with central ulcerations. Histologically, there is infiltration of the recticular dermis by endothelial cells due to excess vascular proliferation. Herein, we report a patient who presented with unbearable bilateral breast pain with characteristic "reticular vascular marking" of her breasts, who was diagnosed with diffuse dermal angiomatosis. We were able to successfully treat our patient with a tapered isoretinoin regimen.
