RESUMEN

BACKGROUND: Patient and clinician reminders were implemented as part of an adherence improvement project at University of Florida (UF) Internal Medicine Clinics. We sought to assess colorectal cancer (CRC) screening completion rates among patients not up-to-date with screening following distribution of reminders and to identify characteristics correlated with screening outcomes. METHODS: Retrospective chart review was performed for patients not up-to-date with CRC screening for whom at least one reminder (patient and/or clinician) was issued in June 2018. The primary endpoint, the completion of a CRC screening test, is characterized as the ratio of completed screening tests to the number of patients not up-to-date with screening. All analyses were performed using R 4.0 software. RESULTS: Of the 926 patients included, 403 (44%; 95% CI, 0.40-0.47) completed a CRC screening test within 24 months following a reminder. Family history of CRC (relative risk (RR) 1.33; P = 0.007), flu immunization within two years of the reminder (RR 1.23; P = 0.019), and receiving a patient reminder either alone (RR 1.62; P < 0.001) or in combination with a clinician reminder (RR 1.55; P = 0.006) were positively associated with CRC screening completion. Reporting being divorced, separated, or widowed was negatively associated with screening completion (RR 0.70; P = 0.004). CONCLUSION: Reminders, in particular patient reminders, seem to be an effective method to enhance screening among patients not up-to-date with CRC screening. This study suggests that reminder efforts should be focused at the level of the patients and provides insight on target populations for practical interventions to further increase CRC screening adherence.

RESUMEN

We report the design and characterization of UNC3866, a potent antagonist of the methyllysine (Kme) reading function of the Polycomb CBX and CDY families of chromodomains. Polycomb CBX proteins regulate gene expression by targeting Polycomb repressive complex 1 (PRC1) to sites of H3K27me3 via their chromodomains. UNC3866 binds the chromodomains of CBX4 and CBX7 most potently, with a K(d) of ∼100 nM for each, and is 6- to 18-fold selective as compared to seven other CBX and CDY chromodomains while being highly selective over >250 other protein targets. X-ray crystallography revealed that UNC3866's interactions with the CBX chromodomains closely mimic those of the methylated H3 tail. UNC4195, a biotinylated derivative of UNC3866, was used to demonstrate that UNC3866 engages intact PRC1 and that EED incorporation into PRC1 is isoform dependent in PC3 prostate cancer cells. Finally, UNC3866 inhibits PC3 cell proliferation, consistent with the known ability of CBX7 overexpression to confer a growth advantage, whereas UNC4219, a methylated negative control compound, has negligible effects.

RESUMEN

Mastectomies for both cancer resection and risk reduction are becoming more common. Existing chest wall irregularities are found in these women presenting for breast reconstruction after mastectomy and can pose reconstructive challenges. Women who desired breast reconstruction after mastectomy were evaluated preoperatively for existing chest wall irregularities. Case reports were selected to highlight common irregularities and methods for improving cosmetic outcome concurrently with breast reconstruction procedures. Muscular anomalies, pectus excavatum, scoliosis, polythelia case reports are discussed. Relevant data from the literature are presented. Chest wall irregularities are occasionally encountered in women who request breast reconstruction. Correction of these deformities is possible and safe during breast reconstruction and can lead to improved cosmetic outcome and patient satisfaction.

RESUMEN

BACKGROUND: The pedicled transverse rectus abdominis myocutaneous (TRAM) flap is a reliable reconstructive option in breast cancer patients; however, it carries known risk of donor site hernia formation. Some hormonal therapy drugs have been associated with hernia formation in animal models. Minimal data exist concerning impact of hormonal therapy for breast cancer on abdominal donor site complications after breast reconstruction. METHODS: Patients who underwent TRAM flap for breast cancer or high-risk status at a single institution by the senior author from 2003 to 2015 were identified. Charts were reviewed. Patient demographics, comorbidities, treatments, and abdominal complications were recorded. Patients were divided into groups based on use of hormonal therapy as well as exposure to specific drugs. Statistical analyses were performed. RESULTS: A total of 358 patients were included. Overall hernia rate was 5.9%. About 231 (64.5%) patients had hormonal therapy, whereas 127 (35.5%) did not. Difference in hernia formation was not statistically significant between the hormonal therapy group (6.9%) and the no hormonal therapy group (3.9%; P = 0.359). Patients exposed to tamoxifen and those exposed to anastrozole had no significant difference in complication rates compared with the no hormonal therapy group, whereas patients exposed to letrozole had increased rate of hernia (13.5%; P = 0.037) and infection (21.6%; P = 0.013) compared with the no hormonal therapy group (3.9% and 7.1%, respectively). CONCLUSIONS: Hormonal therapy is a useful adjunct for chemoprevention in breast cancer; however, use of letrozole in patients undergoing reconstruction with pedicled TRAM can lead to increase in certain complication rates.

RESUMEN

OBJECTIVE: Considerable attention has been given to patient-reported outcomes in breast reconstruction. The objective of this study is to evaluate the effect of postreconstruction change in breast volume on validated patient satisfaction survey scores. METHODS: Patients undergoing skin-sparing mastectomy followed by tissue expander/implant reconstruction between July 2010 and July 2014 by a single surgeon were given postoperative patient-reported satisfaction surveys (BREAST-Q). Retrospective chart review of patients with completed surveys was undertaken to record patient characteristics and compare preoperative breast volume (extrapolated from mastectomy mass) with postoperative implant volume, and percent change in volume was calculated. Regressions were utilized to correlate percent change with satisfaction in each category. RESULTS: A total of 160 patient surveys were included. Sixty-five percent of breasts analyzed had increased volume after reconstruction, whereas 35% had decreased volume. The increased volume group had significantly lower body mass index (P = 0.0001) and was significantly younger (P = 0.009) than the decreased volume group. Patients who experienced increase in breast volume reported statistically greater satisfaction with breasts (P = 0.019), overall outcome (P = 0.012), sexual well-being (P = 0.002), and information (P = 0.042) compared with the decreased volume group. Moreover, linear regression revealed that as percent change increased, so did satisfaction with outcome (P = 0.02), sexual well-being (P = 0.005), information (P = 0.018), and surgeon (P = 0.036). Notably, there was not a significant difference in complication rate (P = 0.146) or tumor margin (0.914) between the groups. CONCLUSION: Patients who undergo tissue expander/implant breast reconstruction with final implants that are larger in volume than their native breasts have increased patient satisfaction scores in several categories without increase in complication rate or difference in tumor margin. There is a positive linear relationship between percent change and patient satisfaction.

RESUMEN

OBJECTIVE: Assess the prevalence of nonalcoholic fatty liver disease (NAFLD) and of liver fibrosis associated with nonalcoholic steatohepatitis in unselected patients with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS: A total of 561 patients with T2DM (age: 60 ± 11 years; BMI: 33.4 ± 6.2 kg/m2; and HbA1c: 7.5 ± 1.8%) attending primary care or endocrinology outpatient clinics and unaware of having NAFLD were recruited. At the visit, volunteers were invited to be screened by elastography for steatosis and fibrosis by controlled attenuation parameter (≥274 dB/m) and liver stiffness measurement (LSM; ≥7.0 kPa), respectively. Secondary causes of liver disease were ruled out. Diagnostic panels for prediction of advanced fibrosis, such as AST-to-platelet ratio index (APRI) and Fibrosis-4 (FIB-4) index, were also measured. A liver biopsy was performed if results were suggestive of fibrosis. RESULTS: The prevalence of steatosis was 70% and of fibrosis 21% (LSM ≥7.0 kPa). Moderate fibrosis (F2: LSM ≥8.2 kPa) was present in 6% and severe fibrosis or cirrhosis (F3-4: LSM ≥9.7 kPa) in 9%, similar to that estimated by FIB-4 and APRI panels. Noninvasive testing was consistent with liver biopsy results. Elevated AST or ALT ≥40 units/L was present in a minority of patients with steatosis (8% and 13%, respectively) or with liver fibrosis (18% and 28%, respectively). This suggests that AST/ALT alone are insufficient as initial screening. However, performance may be enhanced by imaging (e.g., transient elastography) and plasma diagnostic panels (e.g., FIB-4 and APRI). CONCLUSIONS: Moderate-to-advanced fibrosis (F2 or higher), an established risk factor for cirrhosis and overall mortality, affects at least one out of six (15%) patients with T2DM. These results support the American Diabetes Association guidelines to screen for clinically significant fibrosis in patients with T2DM with steatosis or elevated ALT.

RESUMEN

This article was migrated. The article was marked as recommended. Self-promotion can be challenging for physicians who are looking to advance their careers. While they want to make their successes in the workplace known, they are afraid of coming off as aggressive and turning off the people that they are trying to impress with their accomplishments. This dilemma led to the coining of the term "graceful self-promotion" (GSP), a method of making one's accomplishments and abilities visible with tact and humility. The Division of General Internal Medicine at the University of Florida undertook a faculty development session focusing on GSP skills. The session started with participants interacting with each other using Bingo cards which listed GSP strategies in order to facilitate discussion. This was followed by an interactive discussion on barriers to career advancement and strategies to practice GSP. Changes in physician knowledge regarding self-promotion techniques and attitudes towards its importance were assessed using statistical tests from responses to pre- and post-surveys. We measured a positive change in physician attitudes towards their ability to self-promote following the information session (p-value < 0.005). Perceptions about the importance of self-promotion activities improved as well (p-value < 0.005). Participants comments revealed greater understanding of need for networking, developing a spirit of generativity, and having a prepared Elevator Speech. In this era where pressure to generate clinical revenue allows for limited faculty development time even a short 1-hour session can create awareness about importance of GSP for academic advancement, strategies for participants to use, and awareness of barriers to GSP.

RESUMEN

Pharmacogenetic testing (PGT) is increasingly being used as a tool to guide clinical decisions. This article describes the development of an outpatient, pharmacist-led, pharmacogenetics consult clinic within internal medicine, its workflow, and early results, along with successes and challenges. A pharmacogenetics-trained pharmacist encouraged primary care physicians (PCPs) to refer patients who were experiencing side effects/ineffectiveness from certain antidepressants, opioids, and/or proton pump inhibitors. In clinic, the pharmacist confirmed the need for and ordered CYP2C19 and/or CYP2D6 testing, provided evidence-based pharmacogenetic recommendations to PCPs, and educated PCPs and patients on the results. Operational and clinical metrics were analyzed. In two years, 91 referred patients were seen in clinic (mean age 57, 67% women, 91% European-American). Of patients who received PGT, 77% had at least one CYP2C19 and/or CYP2D6 phenotype that would make conventional prescribing unfavorable. Recommendations suggested that physicians change a medication/dose for 59% of patients; excluding two patients lost to follow-up, 87% of recommendations were accepted. Challenges included PGT reimbursement and referral maintenance. High frequency of actionable results suggests physician education on who to refer was successful and illustrates the potential to reduce trial-and-error prescribing. High recommendation acceptance rate demonstrates the pharmacist's effectiveness in providing genotype-guided recommendations, emphasizing a successful pharmacist-physician collaboration.

RESUMEN

BACKGROUND: Direct oral anticoagulants (DOACs) are high risk medications with short half-lives making adherence vitally important. Global measures for adherence have been described; however, there is a lack of patient-level data on adherence. METHODS: This prospective, single-center study in an interdisciplinary internal medicine clinic included patients referred by their primary care physician for DOAC therapy evaluation. Patients were interviewed by a clinical pharmacist who confirmed dose and indication. Adherence was evaluated by asking how it was taken, at what time(s) of the day, and how many doses of their DOAC were missed. Labs and concomitant drugs were evaluated and patients received medication counseling. If any issues arose, the pharmacist would work together with the physician to resolve them. FINDINGS: Of 116 visits from 72 patients, an intervention was needed in 79 visits (68·1%). The most common problem identified was related to adherence: non-adherence to timing of dosing (n = 30), non-adherence to frequency of dosing (n = 5), and non-adherence to administration with food when indicated (n = 11). Adherence issues were present in 11 (61·1%) visits in patients taking rivaroxaban and 31 (33·0%) visits in patients taking apixaban. INTERPRETATION: An interdisciplinary DOAC service provided interventions for the majority of patients referred for DOAC therapy evaluation. The most frequent problem was non-adherence, with more than a third of patients found to be non-adherent to the timing of their medication administration.

RESUMEN

A 28-year-old man presented to our clinic over the course of 3 weeks with symptoms that progressed from mild headaches to fever, fatigue, myalgia and an enlarged right preauricular lymph node with ipsilateral conjunctivitis and upper eyelid weakness. Our differential included Epstein Barr Virus/Cytomegalovirus mononucleosis, bacterial conjunctivitis and lymphoma. We evaluated with CBC, EBV IgM Ab, lactate dehydrogenase level and a CMV IgG Ab which were all within normal limits. During his third visit, we discovered our patient had been scratched by two stray kittens he had adopted 2 months prior. We confirmed the diagnosis with a positive Bartonella henselae IgG level and diagnosed him with cat scratch disease presenting as Parinaud's oculoglandular syndrome. He was treated with a 5-day course of Azithromycin 250 mg with definitive improvement.

RESUMEN

Tracheocutaneous fistula (TCF) is a complication occurring after decannulation of a long-term tracheostomy and can lead to significant morbidity. We describe a case of a TCF in a burn patient treated without surgery. No previous cases have been described. A 65-year-old woman presented with symptomatic hypertrophic burn scar contractures of the anterior neck 6 months after undergoing excision and grafting of full-thickness burns to the neck and chest. She had a history of tracheostomy placement at the time of burn. Two months later, she was decannulated with no evidence of TCF. She subsequently underwent excision of hypertrophic burn scar contractures of the neck with placement of bilayer wound matrix followed by split-thickness skin grafting. Postoperatively she was noted to have a TCF with subgraft emphysema and difficulty in phonation and respiration. With local wound care, the TCF closed spontaneously and a new skin graft was placed uneventfully. At 18 months postoperatively, fistula closure was maintained with good functional and aesthetic outcome. Conservative management of an iatrogenic TCF in a burn patient may result in adequate soft-tissue coverage and allow for subsequent successful skin grafting. This method affords minimal morbidity to the patient and is a viable alternative to more elaborate flap reconstruction.

RESUMEN

The ruptured hypogastric artery aneurysm (RHAA) is a rare clinical entity with an evolving and dynamic therapeutic armamentarium. The anatomical location and varied clinical presentation can pose a challenge for successful repair. Recently, endovascular and hybrid operative repairs have significantly improved the historically high-operative mortality rate. We present an illustrative case and contemporary review of the literature with respect to RHAA.

RESUMEN

BACKGROUND: Recent studies have suggested that sentinel lymph node (SLN) biopsy is of limited value in desmoplastic melanoma. This study was performed to compare the rate of positive SLN biopsy in the Surveillance, Epidemiology, and End Results (SEER) database with that of a multi-institutional clinical trial and to investigate relevant prognostic factors in desmoplastic melanoma. STUDY DESIGN: Patients with desmoplastic melanoma ≥1.0 mm Breslow thickness, who underwent SLN biopsy in a multi-institutional prospective clinical trial, were combined with a single institution melanoma database (combined database) and compared with patients from the SEER database (1998 to 2009). Disease-free survival (DFS) and overall survival (OS) were summarized using Kaplan-Meier curves and compared using Cox proportional hazard models. RESULTS: The rate of positive SLN in the combined database was 17.0% (8 of 47). By comparison, the rate of positive SLN in SEER was lower: 2.5% (15 of 594). On multivariable analysis, Breslow thickness ≥2.6 mm (hazard ratio 8.17, 95% CI 1.26 to 160.1; p = 0.0259) and an interaction between SLN status and ulceration (p = 0.0013) were independent risk factors for worse OS in the combined database; patients with ulceration and a positive SLN had significantly worse OS. In the combined database on multivariable analysis, SLN positivity (p = 0.0161) and ulceration (p = 0.0004) were independent risk factors for worse DFS. CONCLUSIONS: The rate of positive SLN in desmoplastic melanoma may be higher than that reported in the SEER database. Sentinel lymph node biopsy may be considered as part of the comprehensive staging of desmoplastic melanoma ≥1.0 mm Breslow thickness.

RESUMEN

INTRODUCTION: Many case reports have described anatomical variants of the pectoralis muscles. However, there is a paucity of published literature on the consequence of such presentations in reconstructive breast surgery. METHODS: A 45-year-old female patient with breast cancer presented for left mastectomy and immediate reconstruction with tissue expander. During mastectomy, she was noted to have an extra muscle anterior to her pectoralis major muscle. This variant had not previously been described in the literature and was therefore named the oblique pectoralis anterior. After inspection of the aberrant musculature, the decision was made to release the inferolateral insertion of the accessory muscle with the inferior edge of pectoralis major. An adequate pocket for the expander was created. RESULTS: After routine expansion and implant exchange, muscular coverage of the implant from pectoralis major and the oblique pectoralis anterior muscle approximated 70%. The patient was left with good symmetry and a cosmetic result, despite the challenges presented by her anomalous chest wall musculature. DISCUSSION: Prior knowledge of the various anatomic aberrations described in the literature can prepare a surgeon to properly incorporate and utilize the variant anatomy, should it be encountered, to benefit the outcome of the operation.

RESUMEN

Locking reconstruction plates have led to significant improvement in osteosynthesis and graft anchorage in mandibular reconstruction following the free fibula osteocutaneous flap. Plate extrusion is the most common complication associated with mandibular reconstruction, occurring in approximately 20% to 48% of cases; often necessitating plate removal once the bone flap has united to the mandible. Radiation therapy is a known risk factor to the development of such a complication and it presents further challenges to the successful removal of the reconstruction plate. Several reports have been published regarding plate removal in the setting of orthopedics that describe the management of jammed or stripped locking screws, but few in the setting of mandibular reconstruction. In this case, we report the successful removal of an exposed titanium mandibular reconstruction plate from a 41-year-old woman 12 months after her initial reconstruction with a free fibula osteocutaneous flap and radiation therapy. The approach was selected because the chin and neck skin could not be expected to be raised for full plate exposure secondary to radiation-induced skin changes (thinning and friability). We also discuss the use of previously employed methods of plate removal in various settings as well as their inherent strengths and weaknesses.

RESUMEN

No report to date describes the added risk traumatic, degloving injuries of the oral cavity may pose when treating fractures of the mandible. The authors describe the oral degloving injury, characterized by separation of periosteum and soft tissue of the anterior floor of the mouth from the inner cortex of the anterior segment. Vascular anatomy of the floor of the mouth is reviewed as a prelude to a description of pathomechanics of the injury and a case report. The higher incidence of oral degloving in youth and in young adulthood and parallels in elective, orthognathic surgery are identified. When this unusual clinical presentation occurs, and when open reduction of fractures of the anterior segment is chosen, a vestibular incision is best avoided. Instead, a submental or upper neck incision is chosen for sufficient exposure to allow reduction and the application of appliances. Meticulous closure of the intraoral void is achieved using one of two techniques, depending on the level of degloving.
