Undertriage of major trauma patients at a university hospital: a retrospective cohort study.

BACKGROUND: Studies show increased mortality among severely injured patients not met by trauma team. Proper triage is important to ensure that all severely injured patients receive vital trauma care. In 2017 a new national trauma plan was implemented in Norway, which recommended the use of a modified version of "Guidelines for Field Triage of Injured Patients" to identify severely injured patients. METHODS: A retrospective study of 30,444 patients admitted to Haukeland University Hospital in 2013, with ICD-10 injury codes upon discharge. The exclusion criteria were department affiliation considered irrelevant when identifying trauma, patients with injuries that resulted in Injury Severity Score < 15, patients that did receive trauma team, and patients admitted > 24 h after time of injury. Information from patient records of every severely injured patient admitted in 2013 was obtained in order to investigate the sensitivity of the new guidelines. RESULTS: Trauma team activation was performed in 369 admissions and 85 patients were identified as major trauma. Ten severely injured patients did not receive trauma team resuscitation, resulting in an undertriage of 10.5%. Nine out of ten patients were men, median age 54 years. Five patients were 60 years or older. All of the undertriaged patients experienced fall from low height (< 4 m). Traumatic brain injury was seen in six patients. Six patients had a Glasgow Coma Scale score ≤ 13. The new trauma activation guidelines had a sensitivity of 95.0% in our 2013 trauma population. The degree of undertriage could have been reduced to 4.0% had the guidelines been implemented and correctly applied. CONCLUSIONS: The rate of undertriage at Haukeland University Hospital in 2013 was above the recommendations of less than 5%. Use of the new trauma guidelines showed increased triage precision in the present trauma population.

Defining recurrence of nonmelanoma skin cancer after Mohs micrographic surgery: Report of the American College of Mohs Surgery Registry and Outcomes Committee.

BACKGROUND: Standardized definitions and methods of surveillance for local recurrence of nonmelanoma skin cancer are critical in determining cure rates attributed to treatment modalities. OBJECTIVE: We sought to offer a standard definition of local recurrence after surgical treatment of nonmelanoma skin cancer and to propose an acceptable surveillance period and tracking methods. METHODS: A literature search was performed for background definitions of local recurrence and tracking methods. The American College of Mohs Surgery (ACMS) Registry and Outcomes Committee then conducted a modified Delphi process to arrive at consensus definitions. RESULTS: We define local recurrence as a tumor with comparable histology, with contiguity to the surgical scar after treatment, and that arises within the area of the previously treated tumor. LIMITATIONS: This project reports the results of a modified Delphi method process involving members of the ACMS. The model described may not be useful for nonexcision type treatments such as topical chemotherapy, electrodessication and curettage, or radiation treatment. CONCLUSIONS: Previous definitions of recurrence and surveillance methods after surgical treatment of nonmelanoma skin cancer are variable and nonstandard. We describe consensus standards for defining and tracking recurrence that should allow for consistent scientific evaluation and development of performance data in skin cancer outcomes registries.

Detection of human papillomavirus DNA in cutaneous squamous cell carcinoma among immunocompetent individuals.

The presence of certain types of human papillomavirus (HPV) is a known risk factor for the development of anogenital squamous cell carcinomas (SCCs). A similar association has been hypothesized for cutaneous SCCs, although, to our knowledge, no studies to date have combined sensitive HPV DNA detection techniques with epidemiologic data controlling for known risk factors to explore the association. We designed a case-control study examining HPV prevalence using highly sensitive PCR-detection assays in tissue samples from 85 immunocompetent patients with histologically confirmed SCCs and 95 age-matched individuals without a prior history of skin cancer. A standardized interview was administered to all study subjects to collect information pertaining to potential confounding variables. The overall detection rate of HPV DNA was high in case lesions (54%) and perilesions (50%) and in both sun-exposed normal tissue (59%) and non-sun-exposed normal tissue (49%) from controls. In comparing case tissue to control tissue, there was no differential detection of HPV DNA across various HPV species. However, HPV DNA from beta-papillomavirus species 2 was more likely to be identified in tumors than in adjacent healthy tissue among cases (paired analysis, odds ratio=4.0, confidence interval=1.3-12.0). The high prevalence of HPV DNA detected among controls suggests that HPV DNA is widely distributed among the general population. However, the differential detection of HPV beta-papillomavirus species in tumors among cases suggests that certain HPV types may be involved in the progression of cutaneous SCCs.

Repair of the philtrum: an illustrative case series.

BACKGROUND: Distortion of the philtrum, which lends considerable symmetry to the midface, leads to a poor esthetic outcome. OBJECTIVE: This case series describes reconstructive approaches to six philtral defects after Mohs micrographic surgery. Reconstructive approaches including advancement flaps, full-thickness skin grafts, and second-intention healing are illustrated. Postoperative complications included graft hypertrophy, irregularity of the graft surface, graft color mismatch, tenderness, and slight eclabium, which improved with dermabrasion or intralesional triamcinolone. CONCLUSION: The reasonable success of full-thickness skin grafts demonstrated here provides an additional approach to philtral repairs, especially when combined with traditional advancement flaps.

Nasalis island pedicle flap in nasal ala reconstruction.

BACKGROUND: Defects of the nasal ala can be difficult to repair in a one-stage procedure. We describe a laterally based nasalis myocutaneous island pedicle flap to repair small but deep defects of the superior nasal ala. OBJECTIVE: To describe a single-stage flap for repair of small defects on the nasal ala that confines the repair to one cosmetic unit. METHODS: We discuss the anatomy of the flap and illustrate the method of placing the flap. RESULTS: We present several case examples and discuss potential applications of the flap. We also discuss the flap's limitations by citing an example of necrosis. CONCLUSIONS: The nasalis myocutaneous island pedicle flap for repair of nasal alar defects is a new application of a one-stage procedure that yields excellent functional and cosmetic results. Knowledge of the limitations and the anatomy of the flap is crucial for a good outcome.

Management of lentigo maligna and lentigo maligna melanoma with staged excision: a 5-year follow-up.

OBJECTIVE: To assess the long-term cure rate for treatment of lentigo maligna (LM) and lentigo maligna melanoma (LMM) by means of a staged, margin-controlled, vertical-edged excision with rush permanent specimens and a radial sectioning technique. DESIGN: Retrospective follow-up study. SETTING: University-affiliated and private-practice dermatologic surgery clinics. PATIENTS: Fifty-nine patients treated for 55 LMs and 7 LMMs between January 1, 1990, and December 31, 2001. INTERVENTIONS: The technique included vertical excision with initial 2- to 3-mm margins examined by rush permanent sections (prepared and read within 24 hours). Further excision took place as guided by histologic findings. Data on patient and lesion characteristics were obtained via a medical chart review. Patients were then contacted and examined for local recurrence. Biopsies were performed on all patients with possible recurrence on clinical examination. MAIN OUTCOME MEASURES: Local recurrence of LM or LMM. RESULTS: After a mean follow-up of 57 months (median, 54 months; 293.8 person-years), 95% of patients were free of recurrence. Three patients had local recurrence and no patients had evidence of metastasis. Two of the 3 local recurrences were of previously excised LM, and 1 was of an LMM. Half (32) of all lesions required 2 or more stages. One required more than 4 stages. The average margin of excision was 0.55 cm. Three of the 58 lesions read as LM on biopsy were found to have invasive disease (LMM) at the time of definitive excision. CONCLUSIONS: The technique described herein for the treatment of LM and LMM provides a long-term disease-free survival of 95%. The cure rate is greater than that reported for standard excision and is similar to that for other margin-control techniques. To our knowledge, this is the largest reported study and has the longest follow-up for this excision method for LM and LMM.
