Wound Healing Society 2023 update on guidelines for arterial ulcers.

The Wound Healing Society guidelines for the treatment of arterial insufficiency ulcers were originally published in 2006, with the last update in 2014. These guidelines provided recommendations, along with their respective levels of evidence, on seven categories: diagnosis, surgery, infection control, wound bed preparation, dressings, adjuvant therapy and long-term maintenance. Over the last 9 years, additional literature regarding these aspects of arterial ulcer management has been published. An advisory panel comprised of academicians, clinicians and researchers was chosen to update the 2014 guidelines. Members included vascular surgeons, internists, plastic surgeons, anaesthesiologists, emergency medicine physicians and dermatologists, all with expertise in wound healing. The goal of this article is to evaluate relevant new findings upon which an updated version of the guidelines will be based.

Stethoscope hygiene: Using cultures and real-time feedback with bioluminescence-based adenosine triphosphate technology to change behavior.

BACKGROUND: Stethoscope hygiene is rarely done despite guideline recommendations. We wanted to determine whether demonstrating what is growing on the stethoscopes of providers via culture or bioluminescence technology alters perceptions and improves compliance. METHODS: Providers were given the opportunity to (1) culture their stethoscopes before and after disinfection with alcohol pads, alcohol-based hand rub, or hydrogen peroxide disinfectant wipes and (2) swab stethoscopes for bioluminescence-based adenosine triphosphate testing before and after disinfection. Outcomes were observed for hand and stethoscope hygiene rates and before and after intervention survey responses. The bacteria that were isolated, colony-forming units (CFU), and bioluminescence scores were tracked. RESULTS: A total of 1,245 observed hand hygiene opportunities showed that compliance improved from 72.5%-82.3% (P < .001). In addition, 590 observed patient-provider encounters revealed no significant change in stethoscope hygiene rates of 10% initially and 5% afterward (P = .08), although self-reported rates trended from 56%- 67% postintervention (P = .06). Perceptions regarding stethoscope hygiene importance improved (8.5/10 to 9.3/10; P = .04). Disinfection with alcohol pads, alcohol-based hand rub, and hydrogen peroxide disinfectant wipes were equivalent in CFU reduction (P = .21). CONCLUSIONS: Showing providers what is growing on their stethoscopes via cultures and bioluminescence technology before and after disinfection improved "buy in" regarding stethoscope hygiene importance. Both methods were rated as having an equal impact, however, objective observations failed to show improvement.

Auricular Acupuncture and Skin-Cancer Detection: An Opportunity.

Background: Auricular acupuncture is effective for many patients with pain. Many skin malignancies and precancerous lesions are found on the head and neck. Practitioners of acupuncture are in a unique situation to detect cutaneous malignancy at an early state. Case: An 83-year-old man referred for Battlefield Acupuncture was found to have a scalp lesion suspicious for malignancy as well as several precancerous lesions. Results: Referral to a dermatologist led to excision of a basal-cell cancer and treatment of actinic keratoses. Conclusions: Practitioners of auricular acupuncture should be familiar with common skin cancers and precancerous lesions; these practitioners are in a unique situation to detect these common skin lesions.

A rare 'incidentaloma' found on low-dose CT screening for lung cancer: 'scanner beware'.

Screening for lung cancer with low-dose computed tomography (LDCT) has been shown to reduce mortality and has been recommended by the U.S. Preventive Services Task Force for adults 55 to 80 years of age with a 30 pack-year smoking history who are either current smokers or those that quit within 15 years. However, the overwhelming majority of abnormalities detected are not from malignancy. We report a case of pulmonary Langerhans' cell histiocytosis, here-to-fore thought of as extremely uncommon, and make readers aware that this may be increasingly found as LDCT is more widely adopted.

Now you see/C it.

Bleeding disorders are common. In addition to thinking about disorders relating to abnormal platelets or clotting factors, clinicians should consider disorders of vascular integrity in their differential diagnosis. We present a patient with atypical, spontaneous bleeding that was due to scurvy, an often overlooked cause. Clinicians should be aware of the risk factors for the development of scurvy, such as poor dietary intake, male gender, smoking, alcohol abuse, as well as its classic manifestations, including gingival bleeding, spontaneous bruising, corkscrew hairs, and poor wound healing, A heightened awareness may lead to earlier diagnosis and treatment.

Treatment of Basal Cell Carcinoma in the Elderly: What Nondermatologists Need to Know.

As the population ages and incidence of basal cell carcinoma continues to increase, we will be faced more frequently with difficult treatment decisions for basal cell carcinoma in the elderly. Different treatment options, including surgical excision, electrodessication and curettage, cryosurgery, imiquimod, photodynamic therapy, 5-fluorouracil, radiation therapy, vismodegib, combination therapy, and observation, may be considered on the basis of tumor characteristics. Given the wide range of therapeutic options, treatments can be tailored to achieve patients' goals of care within their anticipated life expectancy.

Systemic Inflammatory Disease and Its Association With Type II Endoleak and Late Interventions After Endovascular Aneurysm Repair.

IMPORTANCE: Abdominal aortic aneurysms are associated with chronic inflammation within the aortic wall, and previous studies have suggested that chronic inflammation may be a consequence of a dysregulated and persistent autoimmune response. Persistent aortic remodeling after aneurysm repair could place the patient at risk for endoleak or sac rupture. OBJECTIVE: To determine whether patients with systemic inflammatory disease and large aneurysms have persistent aortic remodeling after endovascular aneurysm repair (EVAR). DESIGN, SETTING, AND PARTICIPANTS: The records of all patients who underwent EVAR between July 2002 and June 2011 at the Veterans Affairs Connecticut Healthcare System were included in this retrospective review. Patients were considered to have a systemic inflammatory disease when confirmed by a referring specialist. Post-EVAR surveillance was performed by yearly imaging. INTERVENTION: Endovascular aneurysm repair. MAIN OUTCOMES AND MEASURES: Significant endoleak, defined as endoleak and sac diameter increase of 0.5 cm or greater. RESULTS: A total of 51 of 79 patients (65%) had a systemic inflammatory disease. These patients had similar comorbid conditions compared with patients without inflammation but significantly greater numbers of major postoperative complications after EVAR (23.5% vs 3.6%; P = .02) and overall postoperative complications after EVAR (27.5% vs 7.1%; P = .03). Patients with a history of systemic inflammatory disease developed more endoleaks (45.1% vs 17.9%; P = .02) and late sac expansion (51.0% vs 21.4%; P = .01) and required more interventions (21.6% vs 3.6%; P = .03) during long-term follow-up. Systemic inflammatory disease was significantly associated with significant endoleak (odds ratio, 5.18; 95% CI, 1.56-17.16; P = .007). CONCLUSIONS AND RELEVANCE: Patients with systemic inflammatory disease are at high risk for postoperative complications, type II endoleak, sac expansion, and additional interventions after EVAR. Additional strategies for improving the efficacy of EVAR in these patients may be warranted.

Advanced, neglected basal cell carcinoma.

Although basal cell carcinoma (BCC) rarely metastasizes and has a cure rate >95% when diagnosed early in its course, BCC causes significant morbidity and presents an enormous burden to the healthcare system worldwide. Patients who present late in the course of their disease are particularly challenging in that their treatment can be more complicated and less likely to be effective than had they presented earlier. Given the high prevalence of this malignancy and the morbidity associated with a late presentation, healthcare professionals should be familiar with the consequences of neglected BCCs, as well as their management after presentation. Knowledge of patient risk characteristics may allow earlier engagement and diagnosis of patients, before more significant morbidity occurs.

Screening for prostate cancer: are digital rectal examinations being performed?

OBJECTIVE: Prostate cancer is common and prostate cancer screening is controversial; this retrospective observational study was conducted to determine the prevalence of digital rectal examination (DRE) in those in whom a prostate-specific antigen (PSA) test was performed. METHODS: A manual review was performed of the electronic medical record for male veterans in the VA Connecticut Healthcare System without a history of known prostate cancer aged between 50 and 74 years who underwent PSA testing. MAIN OUTCOMES: Documentation of DRE (or refusal) within 12 months before or after the performance of a PSA test. RESULTS: Less than half (47.6%) of patients underwent DRE. An additional 6.9% were offered DRE and refused. Although the provider gender was not associated with DRE, resident physicians were less likely to perform DRE than nonresidents; P = 0.01. Patients whose PSA was > 4.0 ng/mL were more likely to undergo DRE than those whose PSA was ≤ 4.0 ng/mL; P = 0.002. Those with body mass index (BMI) > 40 kg/m 2 were less likely to undergo DRE than those with BMI < 30 kg/m 2 ; P = 0.04. CONCLUSIONS: Screening for prostate cancer remains controversial. We found a low rate of DRE among veterans in whom prostate cancer screening was entertained. Although the provider gender does not seem to influence DRE, resident physicians were less likely to perform DRE than other providers. Our finding that BMI > 40 kg/m 2 is associated with a lower rate of DRE than those with BMI < 30 kg/m 2 is consistent with screening for other cancers and should be explored further.

Gynecomastia: etiologies, clinical presentations, diagnosis, and management.

Gynecomastia is a common finding that is present in up to 57% of men. It is caused by proliferation of the mammary glands, which leads to the development of dense subareolar tissue. The condition results from both physiologic (eg, hypogonadism, altered estrogen-to-androgen ratio) and nonphysiologic (eg, drugs, herbal products) causes. Most cases are benign and resolve spontaneously. Treatment is usually unnecessary, although there are specific signs and symptoms that warrant further workup. Psychosocial effects also are of concern, particularly among adolescents. Knowledge of the possible causes of gynecomastia and a thoughtful approach to the patient presenting with this condition can lead to improved outcomes and patient satisfaction. This concise review of the common presentation, etiologies, diagnosis, and treatment of gynecomastia should aid healthcare professionals who may encounter these patients in their practices.

Skin cancer screening and primary prevention: facts and controversies.

Skin cancer is both common and responsible for significant morbidity and mortality. Opportunities for both primary and secondary prevention are available to both dermatologists and non-dermatologists. Counseling selected patients about ultraviolet avoidance and proper use of sunscreens is recommended. Due to technical and financial barriers, no study has conclusively confirmed the benefits of skin cancer screening. Both dermatologists and non-dermatologists often do not perform total body skin examinations during clinical encounters, despite high acceptance rates by patients. Many non-dermatologists would benefit from additional education pertaining to the diagnosis of cutaneous malignancy. Teledermatology may have a role in areas with poor access to dermatologists. There are ample opportunities for more to be learned in the future.
