Surgical treatment algorithm for breast cancer lymphedema-a systematic review.

Background: Various surgical treatments are increasingly adopted and gaining popularity for lymphedema treatment. However, challenges persist in selecting appropriate treatment modalities targeted for individual patients and achieving consensus on choice of treatment as well as outcomes. The systematic review aimed to create a treatment algorithm incorporating the latest scientific knowledge, to provide healthcare professionals and patients with a tool for informed decision-making, when selecting between treatments or combining them in a relevant manner. This systematic review evaluated and synthesized the evidence on the effectiveness of three surgical treatments for breast cancer-related lymphedema (BCRL): lymphovenous anastomosis (LVA), vascularized lymph node transfer (VLNT), and liposuction. Methods: We conducted a systematic search of electronic databases on 18 June 2023, including Medline, Embase, Cochrane Library, Google Scholar, and ClinicalTrials.org. Eligible studies were randomized controlled trials, non-randomized comparative studies, and observational studies that assessed the outcomes of LVA, VLNT, or liposuction in managing BCRL. The primary results of interest were changes in arm volume, lymphatic flow, and quality of life. Two independent reviewers performed the study selection and data extraction. Following this, we systematically reviewed and conducted a risk of bias assessment. Results were qualitatively presented, and a treatment algorithm was developed based on the available data. Results: We identified 16,593 papers, after removal of duplicates. Following assessment of studies, 73 articles met the inclusion criteria, including 2,373 patients. We were not able to conduct a meta-analysis due to considerable heterogeneity in the methodologies and outcome measures across the studies. Liposuction appears effective for patients presenting with non-pitting lymphedema. LVA indicates variable success rate, with some evidence indicating a reduction in limb volume and symptomatic relief amongst early stages of lymphedema. VLNT showed promising results for limb volume reduction and symptom improvement in patients presenting with mild and moderate lymphedema. Conclusions: Liposuction, LVA, and VLNT seem to be effective treatments for BCRL, when targeted for the appropriate patient. Well-conducted high evidence clinical studies in the field are still lacking to uncover the efficacy of surgical treatment for BCRL.

Robot-assisted lymphovenous anastomosis surgery for lymphocele in the groin.

We present the first-in-human robot-assisted microsurgery on a lymphocele in the groin involving a man in his late 60s who had been coping with the condition for 12 months. Despite numerous efforts at conservative treatment and surgical intervention, the lymphocele persisted, leading to a referral to our clinic.Diagnostic techniques, including indocyanine green lymphography and ultrasound, identified one lymphatic vessel draining into the lymphocele. The surgical intervention, conducted with the assistance of a robot and facilitated by the Symani Surgical System (Medical Microinstruments, Calci, Italy), involved a lymphovenous anastomosis and excision of the lymphocele. An end-to-end anastomosis was performed between the lymphatic and venous vessels measuring 1 mm in diameter, using an Ethilon 10-0 suture.The surgery was successful, with no postoperative complications and a prompt recovery. The patient was discharged 3 days postoperatively and exhibited complete recovery at the 14-day follow-up. This case marks the first use of robot-assisted microsurgical lymphovenous anastomosis to address a groin lymphocele, highlighting the benefit of advanced robotic technology in complex lymphatic surgeries.

Further psychometric evaluation of the WOUND-Q: A responsiveness study.

The WOUND-Q is a modular patient-reported outcome measure (PROM) with 13 scales measuring constructs across 4 domains (i.e., wound characteristics, health related quality of life, experience of care and wound treatment). The psychometrics of the WOUND-Q were previously assessed and the 13 scales evidenced good validity and reliability. However, the responsiveness (i.e., ability to detect clinical change) of the WOUND-Q has yet to be assessed. The objective of this study was to evaluate responsiveness for 9 WOUND-Q scales that assess outcomes, in a sample of people 18 years of age or older with chronic wounds that were present for at least 3 months. This study conducted a 4 month follow-up of 421 participants who completed the WOUND-Q as part of a previous psychometric study. Participants completed an online survey answering questions about their current wound state (e.g., number, type, size, smell, drainage), anchor questions about change, as well as the WOUND-Q scales that they had completed in their initial assessment. Pre-defined hypotheses were tested with a 75% acceptance threshold indicating sufficient evidence of responsiveness. Minimally important differences (MIDs) were also calculated using both anchor-based and distribution-based methods. Of 390 invited participants, 320 provided responses, ranging in age from 19 to 84 years. Acceptance of hypotheses ranged from 60% to 100%, with only the Symptom scale not meeting the 75% threshold. The findings of this study provide evidence that the WOUND-Q can validly measure clinical change in patients with chronic wounds.

From static to dynamic: The influence of mechanotransduction on skin equivalents analyzed by bioimaging and RNAseq.

In this study, we explore the impact of mechanical stimuli on skin models using an innovative skin-on-a-chip platform, addressing the limitations of conventional transwell-cultured skin equivalents. This platform facilitates cyclic mechanical stimulation through compression and stretching, combined with automated media perfusion. Our findings, using bioimaging and bulk RNA sequencing, reveal increased expression of Keratin 10 and Keratin 14, indicating enhanced skin differentiation and mechanical integrity. The increase in desmosomes and tight junctions, observed through Claudin-1 and Desmoplakin 1 & 2 analysis, suggests improved keratinocyte differentiation due to mechanical stimulation. Gene expression analyses reveal a nuanced regulatory response, suggesting a potential connection to the Hippo pathway, indicative of a significant cellular reaction to mechanical stimuli. The results show the important influence of mechanical stimulation on skin model integrity and differentiation, demonstrating the potential of our microfluidic platform in advancing skin biology research and pharmaceutical testing.

Identifying health-related quality of life concepts to inform the development of the WOUND-Q.

OBJECTIVE: The impact of hard-to-heal wounds extends beyond traditional clinical metrics, negatively affecting a patient's health-related quality of life (HRQoL). Yet treatment outcomes are seldom measured from the patient's perspective. The purpose of the present study was to perform in-depth qualitative interviews with patients diagnosed with varying types of hard-to-heal wounds to identify outcomes important to them. METHOD: Participants were recruited from wound care clinics in Canada, Denmark, the Netherlands and the US, and were included if they had a hard-to-heal wound (i.e., lasting ≥3 months), were aged ≥18 years, and fluent in English, Dutch or Danish. Qualitative interviews took place between January 2016 and March 2017. An interpretive description qualitative approach guided the data analysis. Interviews were audio-recorded, transcribed and coded line-by-line. Codes were categorised into top-level domains and themes that formed the final conceptual framework. RESULTS: We performed 60 in-depth interviews with patients with a range of wound types in different anatomic locations that had lasted from three months to 25 years. Participants described outcomes that related to three top-level domains and 13 major themes: wound (characteristics, healing); HRQoL (physical, psychological, social); and treatment (cleaning, compression stocking, debridement, dressing, hyperbaric oxygen, medication, suction device, surgery). CONCLUSION: The conceptual framework developed as part of this study represents the outcome domains that mattered the most to the patients with hard-to-heal wounds. Interview quotes were used to generate items that formed the WOUND-Q scales, a patient-reported outcome measure for patients with hard-to-heal wounds.

Further psychometric validation and test-retest reproducibility of the WOUND-Q.

WOUND-Q is a condition-specific patient-reported outcome measure developed for all types of chronic wounds, located anywhere on the body. To establish reliability and validity of a patient-reported outcome measure, multiple pieces of evidence are required. The purpose of this study was to examine the measurement properties of 9 of the 13 WOUND-Q scales and perform a test-retest reproducibility study in an international sample. In August 2022, we invited members of an international online community (Prolific.com) with any type of chronic wound to complete a survey containing the WOUND-Q scales, the Wound-QoL and EQ-5D. A test-retest survey was performed 7 days after the first survey. It was possible to examine the reliability and validity of eight of the nine WOUND-Q scales by Rasch Measurement Theory (RMT). To examine test-retest reproducibility intraclass correlation coefficients (ICCs), the standard error of the measurement and the smallest detectable change were calculated. In total, 421 patients from 22 different countries with 11 different types of chronic wounds took part in this study. Our analyses provided further evidence of the reliability and validity of the scales measuring wound characteristics (assessment, drainage, smell), health-related quality of life (life impact, psychological, sleep, social) and wound treatment (dressing).

"I am just trying to live a life!" -a qualitative study of the lived experience of pressure ulcers in people with spinal cord injuries.

BACKGROUND: Pressure ulcers (PUs) are frequently reported in people with spinal cord injuries (SCI). Wound management in people with SCI involves relieving pressure on the affected area by means of immobilisation and bed rest. The healing time of a PU can vary, but often takes several months or even years, causing people to stay in bed for prolonged periods of time. OBJECTIVE: This study aims to explore the perspectives and lived experiences of people with SCI who are affected by PUs. DESIGN: and method: This study is a qualitative explorative study that employs individual semi-structured in-depth interviews to obtain the narratives of people with SCI and a pressure ulcer. We used a phenomenological-hermeneutic approach that was inspired by Ricoeur's theory of interpretation. The analysis was performed in three levels: Naïve reading, structural analysis and critical interpretation and discussion. PARTICIPANTS: and setting: Ten people with SCI who were being treated in the Danish healthcare system for their PU participated in this study: six participants had experienced a complete traumatic SCI, three had an incomplete traumatic SCI, and one had a non-traumatic complete SCI. The study included nine men and one woman, aged 49-81 years (mean 64). Nine had a PU in the seating area, while one had the ulcer on the leg. RESULTS: The analysis revealed three themes: 1. Struggling to balance prevention with an active, meaningful life, 2. Challenges and consequences of pressure relief protocols and bed rest, 3. Experiencing prolonged and incoherent treatment with varying levels of staff engagement and competencies. CONCLUSIONS: People with SCI and a PU have difficulty balancing their active, redefined lives when subjected to a strict pressure relief protocol. The consequences of immobility caused by pressure relief include reduced social and community participation and decreased quality of life. PU treatment is experienced as incoherent and unnecessarily lengthy, leading to a deterioration in the wounds. Improving PU treatment for people with SCI is of utmost importance and has the potential to benefit not only the people with SCI but also the healthcare system and the economy.

Novel Chip for Applying Mechanical Forces on Human Skin Models Under Dynamic Culture Conditions.

In recent years the need for in vitro skin models as a replacement for animal studies has resulted in significant progress in the development of skin-on-a-chip models. These devices allow the fine control of the microenvironment of the model and the incorporation of chemical and physical stimuli. In this study, we describe the development of an easy and low-budget open-top dynamic microfluidic device for skin-on-a-chip experiments using polydimethylsiloxane and a porous polyethylene terephthalate membrane. The chip allows the incorporation of compressive stimuli during the cultivation period by the use of syringe pumps. Proof-of-concept results show the successful differentiation of the cells and establishment of the skin structure in the chip. The microfluidic skin-on-a-chip models presented in this study can serve as a platform for future drug and feasibility studies.

Surgical lymphedema models in the mice hindlimb-A systematic review and quality assessment.

BACKGROUND: Lymphedema constitutes a major unsolved problem in plastic surgery. To identify novel lymphedema treatments, preclinical studies are vital. The surgical mouse lymphedema model is popular and cost-effective; nonetheless, a synthesis and overview of the literature with evidence-based guidelines is needed. The aim of this review was to perform a systematic review to establish best practice and support future high-quality animal studies exploring lymphedema treatments. METHODS: We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching four databases (PubMed, Embase, Web of Science, and Scopus) from inception-September 2022. The Animals in Research Reporting In Vivo Experiments 2.0 (ARRIVE 2.0) guidelines were used to evaluate reporting quality. Studies claiming to surgically induce lymphedema in the hindlimb of mice were included. RESULTS: Thirty-seven studies were included. Four main models were used. (1) Irradiation+surgery. (2) A variation of the surgery used by (1) + irradiation. (3) Surgery only (SPDF-model). (4) Surgery only (PLND-model). Remaining studies used other techniques. The most common measurement modality was the caliper. Mean quality coefficient was 0.57. Eighteen studies (49%) successfully induced sustained lymphedema. Combination of methods seemed to yield the best results, with an overrepresentation of irradiation, the removal of two lymph nodes, and the disruption of both the deep and superficial lymph vessels in the 18 studies. CONCLUSION: Surgical mouse hindlimb lymphedema models are challenged by two related problems: (1) retaining lymphedema for an extended period, that is, establishing a (chronic) lymphedema model (2) distinguishing lymphedema from post-operative edema. Most studies failed to induce lymphedema and used error-prone measurements. We provide an overview of studies claiming to induce lymphedema and advocate improved research via five evidence-based recommendations to use: (1) a proven lymphedema model; (2) sufficient follow-up time, (3) validated measurement methods; (4) ARRIVE-guidelines; (5) contralateral hindlimb as control.

Diagnostic Accuracy of Up-Front PET/CT and MRI for Detecting Cervical Lymph Node Metastases in T1-T2 Oral Cavity Cancer-A Prospective Cohort Study.

The diagnostic accuracy of up-front 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) for detecting cervical lymph node metastases in patients with T1-T2 oral squamous cell carcinoma is reported with large discrepancies across the literature. We investigated the sensitivity, specificity, positive and negative predictive value, and accuracy of up-front PET/CT for detecting cervical lymph node metastases in this patient group and compared the performance to magnetic resonance imaging (MRI). In this prospective cohort study, 76 patients with T1-T2 oral squamous cell carcinoma underwent an up-front PET/CT and MRI at the Odense University Hospital from September 2013 to February 2016. Sentinel node biopsy and elective neck dissection were used for histopathological verification of the imaging modalities. Up-front PET/CT was significantly more sensitive than neck MRI (74% vs. 27%, p = 0.0001), but less specific (60% vs. 88%, p = 0.001). The accuracy of PET/CT and neck MRI was comparable (66% vs. 63%, p = 0.85), the PPV was slightly in favor of neck MRI (56% vs. 62%, p = 0.73), the NPV was slightly in favor of PET/CT (77% vs. 63%, p = 0.16). Neither PET/CT nor neck MRI should stand alone for N-staging T1-T2 oral cavity cancer.

CD31 defines a subpopulation of human adipose-derived regenerative cells with potent angiogenic effects.

Cellular heterogeneity represents a major challenge for regenerative treatment using freshly isolated Adipose Derived Regenerative Cells (ADRCs). Emerging data suggest superior efficacy of ADRCs as compared to the ex vivo expanded and more homogeneous ADRCs (= ASCs) for indications involving (micro)vascular deficiency, however, it remains unknown which ADRC cell subtypes account for the improvement. Surprisingly, we found regarding erectile dysfunction (ED) that the number of injected CD31+ ADRCs correlated positively with erectile function 12 months after one bolus of autologous ADRCs. Comprehensive in vitro and ex vivo analyses confirmed superior pro-angiogenic and paracrine effects of human CD31+ enriched ADRCs compared to the corresponding CD31- and parent ADRCs. When CD31+, CD31- and ADRCs were co-cultured in aortic ring- and corpus cavernous tube formation assays, the CD31+ ADRCs induced significantly higher tube development. This effect was corroborated using conditioned medium (CM), while quantitative mass spectrometric analysis suggested that this is likely explained by secretory pro-angiogenic proteins including DKK3, ANGPT2, ANAX2 and VIM, all enriched in CD31+ ADRC CM. Single-cell RNA sequencing showed that transcripts of the upregulated and secreted proteins were present in 9 endothelial ADRC subsets including endothelial progenitor cells in the heterogenous non-cultured ADRCs. Our data suggest that the vascular benefit of using ADRCs in regenerative medicine is dictated by CD31+ ADRCs.

Danish Linguistic Validation and Cultural Adaptation of the LIMB-Q Kids.

(1) Background: Lower Limb deformities include many conditions where pain and physical limitations negatively impact the health-related quality of life (HRQL) of children. The ideal way to assess this impact is by using a Patient Reported Outcome Measure (PROM). Such a condition-specific PROM is under development, called LIMB-Q Kids. This study aimed to perform a translation and cultural adaption (TCA) of the LIMB-Q Kids for use in Danish-speaking children. (2) Methods: TCA guidelines established by the World Health Organization (WHO) and the Professional Society for Health Economics and Outcomes Research (ISPOR) were followed. This process consisted of two independent forward translations, a reconciliation meeting, a backward translation with an assessment, an expert meeting, cognitive interviews with patients, editing based on the interviews, and proofreading. (3) Results: The TCA process contributed to the Danish version of LIMB-Q Kids. The reconciliation meeting resulted in a reconciled Danish version. The revision of the backward translation led to 16 corrections, and after the expert panel meeting, 26 changes were made. Twelve cognitive interviews led to nine changes, which were validated by two further interviews. Proofreading led to no further comments. (4) Conclusions: The TCA process led to a linguistically validated and culturally adapted Danish version of LIMB-Q Kids. This version is being used in the international field test study.

Missed cancer in the Danish head and neck cancer fast-track program: results from a tertiary cancer center.

BACKGROUND: The Danish head and neck cancer fast-track program is a national standardized pathway aiming to reduce waiting time and improve survival for patients suspected of cancer in the head and neck (HNC). Until now, the frequency of missed cancer in the fast-track program has not been addressed. A missed cancer leads to treatment delay and may cause disease progression and worsening of prognosis. The study objective was to estimate the frequency of patients with missed cancers in the Danish HNC fast-track program and to evaluate the accuracy of the program. MATERIALS AND METHODS: Patients who were rejected from the HNC fast-track program because cancer was not found between 1 July 2012 and 31 December 2018 at Odense University Hospital, Denmark were included and followed for three years. Patients were categorized into groups depending on the diagnostic evaluation. Group 1 included patients evaluated with standard clinical work-up without imaging and biopsy. Group 2 included patients evaluated with imaging and/or biopsy in addition to the standard clinical work-up. The local cancer database and electronic patient records were reviewed to determine if a missed cancer had occurred within the follow-up period. RESULTS: A total of 8345 HNC fast-track courses were initiated during the study period. 1499 were patients suspected of recurrent cancer and were excluded leaving 6846 patients to be assessed for eligibility. Of these, 3752 patients were rejected because cancer was not found. Ten patients were subsequently diagnosed with cancer within the follow-up period resulting in an overall frequency of 0.15%. For group 1 and 2, the frequency was 0.04% and 0.10%, respectively. The sensitivity of the fast-track program was 99.67% and the negative predictive value was 99.73%. CONCLUSION: The frequency of missed cancer in a tertiary HNC center following the Danish fast track program is low.

Short term treatment of secondary lymphedema with hyaluronidase injections reduces mouse hindlimb lymphedema.

Lymphedema is a common complication following breast cancer treatment with axillary lymphadenectomy and radiotherapy. Currently, there is no curative treatment for this disease, hence there is a need for new therapeutic suggestions. The aim of this study was to investigate the effect of hyaluronidase (HYAL) injections after inducing hindlimb lymphedema in 36 female C57BL/6 mice. HYAL injections were administered every second day for 14 days in three groups: (1) HYAL for 1 week followed by saline for 1 week, (2) HYAL for 2 weeks, and (3) saline injections for 2 weeks. Volume of the lymphedema limb was weekly assessed with micro-computed tomography (µ-CT) scans for a total course of 6 weeks. Lymph vessel morphometry was assessed in the end of the study after staining cross-sections of the hindlimb for anti-LYVE-1 blindly. Lymphatic function was assessed by lymphoscintigraphy to assess lymphatic clearance. There was a significant reduction of the volume of lymphedema in mice treated with HYAL-7 compared with mice treated with HYAL-14 (p < 0.05) and saline (p < 0.05). No differences were detected in lymph vessel morphometry and the lymphoscintigraphy between groups. Short-term treatment with HYAL-7 might be a potential therapeutic suggestion for secondary lymphedema induced in mouse hindlimbs. In the future, clinical studies are needed to investigate the potential of HYAL treatment in human beings.

Arm and thigh plasty after massive weight loss.

Massive weight loss patients are often left with significant excess skin, which is associated with reduced quality of life and physical limitations due to the symptoms from the excess skin including pendulation, skin maceration, wounding, pain, and infection. The arm and thigh plasty are procedures that reduce the patient's physical symptoms and increase the quality of life by removing excess skin and shaping the remaining tissue. The aim of this review is to describe patient selection for the arm and thigh plasty, discuss indications, surgical principles, and common complications.

Treatment of Breast Cancer-Related Lymphedema With Topical Tacrolimus: A Prospective, Open-Label, Single-Arm, Phase II Pilot Trial.

PURPOSE: Breast cancer-related lymphedema (BCRL) is a chronic, progressive side effect of breast cancer treatment, occurring in one-third of patients treated with axillary lymph node dissection and nodal radiotherapy. Cluster of differentiation 4-positive (CD4+) cells plays a key role in BCRL by facilitating inflammation and inhibiting lymphangiogenesis. Tacrolimus is an anti-inflammatory and immunosuppressive macrolide that targets CD4+ cells. Treatment of lymphedema with topical tacrolimus has revealed promising results in preclinical trials. This clinical trial was aimed at evaluating the feasibility, safety, and effect of tacrolimus in women with stage I or II BCRL, according to the International Society of Lymphology. METHODS: We conducted this open-label, single-arm, phase II pilot trial from September 2020 to April 2021. Eighteen women with BCRL stage I or II BCRL were treated with topical tacrolimus for 6 months and followed up at 3 and 6 months. The primary outcome was arm volume, and secondary outcomes were the lymphedema index (L-Dex), health-related quality of life (HRQoL), lymph flow and function, and safety and feasibility of the trial design. RESULTS: The mean lymphedema arm volume and L-Dex reduced significantly by 130.44 ± 210.13 mL (p < 0.05; relative reduction: 3.6%) and 3.54 ± 4.98 (p < 0.05), respectively, and health-related quality of life scores was improved significantly (p < 0.05). According to the MD Anderson scale, in terms of lymph flow and function, three patients (16.7%) showed improvement, while none showed worsening. Lymph flow or function showed no change according to the Arm Dermal Backflow scale. CONCLUSION: In this trial, treatment with tacrolimus was safe and feasible in women with stage I or II BCRL. Tacrolimus alleviated BCRL in terms of improved arm volume, L-Dex, and HRQoL. Assessments of lymph flow and function were positive, although inconclusive. Larger randomized controlled trials are required to verify these findings. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04541290.

Body Contouring Surgery Improves Long-Term Satisfaction with Appearance and Health-Related Quality of Life after Bariatric Surgery.

BACKGROUND: Patient-reported outcomes are crucial in bariatric surgery (BaS) and body contouring surgery (BC) because patients' goals include improvement in appearance and health-related quality of life (HR-QOL). The BODY-Q is a patient-reported outcome measure developed to measure change in satisfaction with appearance and HR-QOL in BaS and BC patients. The aim of this study was to examine BODY-Q scores over the entire weight loss journey, and to investigate the impact of BC after BaS. METHODS: Patients completed the BODY-Q before and after BaS and BC at four hospital departments in Denmark between 2015 and 2019. Cross-sectional scores were analyzed by phase of weight loss journey using one-way analysis of variance. Scores for patients who provided longitudinal assessments were analyzed using repeated measures analysis of variance and paired t test. The impact of BC was examined over time after BaS, using an independent t test from before BaS through more than 7 years after BaS. RESULTS: The study included 1527 patients who provided 2285 BODY-Q assessments. The cross-sectional analysis by phase of weight loss journey showed higher scores after BaS, lower scores before BC, and highest-level scores after BC. The longitudinal analysis showed higher postoperative mean scores compared with preoperative scores for both BaS and BC. The analysis over time after BaS revealed lower mean scores in patients who did not receive BC. CONCLUSION: The authors' results provide evidence of the positive impact of BaS and BC on patients' lives and emphasize the importance of considering BC to finalize the weight loss journey, as it helps to maintain improvements in appearance and HR-QOL. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Microsurgical replantation of a traumatic total scalp avulsion.

We present a rare case of microsurgical replantation of a total scalp avulsion. A woman in her mid-60s was renovating a tractor when her hair was caught in a column drill resulting in traumatic scalp avulsion. The avulsed scalp involved the eyebrows and the entire hair-covered part of the scalp. The prehospital management and the conservation packing of the scalp was very effective. Microsurgical replantation was achieved with anastomoses of the left superficial temporal artery and one temporal vein on each side. The combination of the prehospital treatment and our university hospital setup made it possible to reattach the scalp with an ischaemia time of approximately 5 hours. A functional and aesthetically pleasing outcome was achieved, and the patient was discharged 6 days postoperatively with a vital scalp and no complaints. Five months postoperatively, she has no sign of alopecia and is regaining sensation and function of the scalp.A woman in her mid-60s was renovating a tractor when her hair was caught in a column drill resulting in traumatic scalp avulsion. The avulsed scalp involved the eyebrows and the entire hair-covered part of the scalp. The prehospital management and the conservation packing of the scalp was very effective.
