larval debridement

Biosurgery (larval therapy) has been used for centuries. However, in recent times, this treatment has been replaced with the use of antibiotics for the treatment of wounds. Due to increasing antibiotic resistance, larval therapy is once again coming to the fore as an effective and efficient treatment. Due to the increasing ageing population, along with an increase in patients with arterial occlusive disease, diabetes and immobility, the number of patients with hard-to-heal wounds will increase. The stressors associated with wounds, such as pain, limited physical functionality, depression and social withdrawal, have a negative impact on patient quality of life...

(1) Background: Developing and implementing strategies for local wound care focused on improving the quality of life related to health status and reducing treatment costs for this patient group poses a challenge to contemporary healthcare systems. The utilization of Maggot Debridement Therapy (MDT) is one potential form of local therapy for preparing wounds for the healing process. The debridement of the wound bed with medical maggots is highly precise, and the defensins produced by the larvae eliminate bacteria and stimulate tissue regeneration...

Despite numerous studies and recommendations, the acceptance of treatments involving medicinal maggots in many clinics has been slow. Several factors may account for this, including the gender of nurses administering the treatment, their level of work experience, and their perceived level of personal stress. The aim of the study was to assess the impact of selected variables (gender, work experience, stress level) on the readiness of nurses to administer maggot debridement therapy (MDT), which is a form of biodebridement...

Patient-centered care (PCC) is recognized as a standard in healthcare for determining high quality. Honoring patients' values, experiences, needs, and preferences in devising, coordinating, and delivering care underscores the enhancement of the therapeutic rapport between patients and healthcare providers. Wound treatment involves a multi-stage process encompassing diagnostics and local wound dressing, which reduces the risk of infection through a coordinated interdisciplinary team. Within this team, nurses undertake specific professional functions and roles...

Forensic entomological evidence is employed to estimate minimum postmortem interval (PMImin), location, and identification of fly samples or human remains. Traditional forensic DNA analysis (i.e., STR, mitochondrial DNA) has been used for human identification from the larval gut contents. Forensic DNA phenotyping (FDP), predicting human appearance from DNA-based crime scene evidence, has become an established approach in forensic genetics in the past years. In this study, we aimed to recover human DNA from Lucilia sericata (Meigen 1826) (Diptera: Calliphoridae) gut contents and predict the eye and hair color of individuals using the HIrisPlex system...

BACKGROUND: This is the first clinical trial to investigate the effectiveness of maggot debridement therapy (MDT) for full-thickness burn injuries in comparison to conventional silver dressings. METHODS: Thirty-one cases with full-thickness (grade III based on ICD-10 classifications version 2019) burns were assigned into larval therapy (15 cases) and conventional treatment (16 cases) groups. Participants in the MDT group have received loose larvae on days 0, 2, 4, and 6, while controls received a conventional regimen comprised of sharp debridement, silver sulfadiazine, antibiotic therapy, and offloading every day...

Infestation of maggots in humans is uncommon because humans are an accidental host for many dipterous larval species. We present a case of wound myiasis in a homeless person that resulted from a neglected minor insect bite wound.

OBJECTIVE: Maggot therapy (MT) or larval debridement therapy is a recognised, effective but underutilised treatment for the management of hard-to-heal wounds and infected ulcers. It is available on NHS prescription in the UK, where wound management is predominantly nurse-led. Anecdotal reports and published literature suggest that nurses may be reluctant to utilise the therapy. The aim of this study was to evaluate the feelings and opinions of nurses regarding the use of MT. METHOD: The first stage of this mixed-methods study was a focus group held to discuss MT and opinions of specialist nurse clinicians...

Infection is one of the main complications that hinder wound healing. Currently, antibiotic-resistant bacteria, such as Methicilin-resistant Staphylococcus aureus (MRSA), are a concern worldwide for both humans and animals. Maggot therapy is re-emerging as an alternative to intractable wounds and may be an option to the traditional antibiotic treatment. Although the species of choice is Lucilia sericata, reports of clinical use have led us to evaluate the efficacy and safety of using Lucilia cuprina larvae on induced infected wounds in Wistar rats...

BACKGROUND: Chronic wounds are susceptible to colonization with gram-positive and gram-negative bacteria that may be resistant to antimicrobial dressings and systemic antibiotics. In January 2004, the US Food and Drugs Administration approved use of medicinal larvae for use in humans and animals for resistant organisms. Despite use in adults, there is a paucity of evidence evaluating its efficacy and safety in the pediatric population. CASE: T was a 5-year-old boy with several chronic wounds infected with multidrug-resistant Pseudomonas aeruginosa...

Purpose: Wounds with dead tissue, purulent wounds, and gangrene are good options for larval therapy. We aim to investigate the effect of larval therapy on diabetic wounds and compare it with traditional treatment. Methods: The sterile larvae were used in wound treatment and the infection rate, Erythrocyte Sedimentation Rate (ESR), and wound size were measured and compared before and after the treatment. Results: The scars of 40 patients in the larval therapy group were evaluated every 10 days and the mean size of the scar decreased from 38...

Objective: Even for very successful peripheral revascularization therapy, treatment is not complete until the ulcerative, gangrenous, and infected wound is closed. This study was performed and compared the outcomes of vacuum-assisted closure (VAC) and maggot debridement therapy (MDT) following peripheral revascularization to accelerate the wound healing process. Methods: We did a prospective randomized clinical trial between January 1, 2014, and June 21, 2019. This study included 72 patients (63 males and nine females)...

The establishment of low-cost, effective, safe and practical methods is necessary to increase the use of larval therapy in wound care. Although studies on external disinfection of calliphorid eggs have been reported, many studies lack data on the effect of disinfection on egg viability and the microorganisms found before disinfection. Therefore, the main objective of this study was to compare three antiseptic solutions, that is, chlorhexidine (5%), Dakin's solution (0.5% NaOCl) and povidone-iodine (10%), in terms of their ability to disinfect Lucilia sericata eggs...

The common green bottle blow fly Lucilia sericata (family, Calliphoridae) is widely used for maggot debridement therapy, which involves the application of sterile maggots to wounds. The larval excretions and secretions are important for consuming necrotic tissue and inhibiting bacterial growth in wounds of patients. Lucilia sericata is also of importance as a pest of sheep and in forensic studies to estimate a postmortem interval. Here we report the assembly of a 565.3 Mb genome from long read PacBio DNA sequencing of genomic DNA...

BACKGROUND: Maggot debridement therapy (MDT), or the use of maggots in dead tissue removal, has been shown to be beneficial in wound healing. Yet MDT in the US is often only used once conventional debridement methods have failed. METHOD: In this study, nine health professionals, experienced in MDT, were interviewed in order to identify and analyse the perceived societal barriers to MDT acceptance and usage in the US. RESULTS: Through qualitative analysis, using the grounded theory framework, this study found that among those interviewed, insurance reimbursement restrictions and stigmatisation of medicinal maggots were the factors driving resistance to MDT use...

In the present study, the efficiency of two formulations of maggot therapy: free-range larvae on the wounds and larvae in a special bag (larval-bag), was compared for healing diabetic ulcers with Wagner 2 diabetic ulcer. This study was conducted as a parallel randomized clinical trial. Out of 281 patients with Wagner grade 2 diabetic ulcers referred to the wound clinic, 54 patients who met the inclusion criteria were randomly assigned to intervention groups. The disinfected larvae of Lucilia sericata were put on the wounds with 2 methods, free-range larvae and larval-bag...

AIM: To determine the impact of larval therapy on the debridement of venous leg ulcers, in comparison to other debridement methods or no debridement. METHOD: Using systematic review methodology, published quantitative studies focusing on the effect of larval therapy on the debridement of venous leg ulcers were included. The search was conducted in January 2020 and updated in May 2021 using CINAHL, PubMed, Embase, and the Cochrane library, and returned 357 records, of which six studies met the inclusion criteria...

BACKGROUND: The debridement of necrotic and infected tissues, which prolong the wound healing process, is important for the preparation of the wound bed. Therefore, wound-bed preparation and debridement are vital components of venous leg ulcer management. We aimed to present a perspective to evaluate the clinical and microbiological efficacy of Maggot Debridement Therapy (MDT) in the treatment of chronic leg ulcers caused by venous insufficiency. METHODS: Thirty-eight patients with chronic venous leg ulcers who were referred to our unit with an MDT request were included in the study...

Lucilia sericata bottle fly worms can be used to heal infected, chronic, or necrotic wounds, including those associated with ulceration and diabetic foot. The study aimed to evaluate changes in the microflora in patients treated with L sericata larvae due to leg ulcers and diabetic foot. One hundred twenty-nine patients diagnosed with lower limb ulceration and diabetic foot were enrolled in the study, of which 80 of them met the eligibility criteria for maggot debridement therapy (MDT). On the contrary, 49 unqualified patients were offered ozone therapy (22 with leg ulcers; 27 with diabetic foot)...

Lucilia sericata, one of the most common species of the Calliphoridae family, is found in large numbers around droppings, garbage and carcasses. This fly species is important in medicine, forensics and veterinary medicine. The larvae of the parasite are important both in veterinary medicine and in combating of the animal diseases, as they cause significant losses in animal production. Since they are one of the first fly colonies to settle on corpses, they can also be used in determining the time of death in the field of forensic medicine...
