Injection of soft tissue fillers plays an important role in facial reconstruction and esthetic treatments such as cosmetic surgery for lip augmentation and wrinkle smoothening. Adverse events are an increasing problem, and recently, it has been suggested that bacteria are the cause of a vast fraction these.
We developed a novel mouse model and evaluated hyaluronic acid gel, calcium hydroxyl apatite microspheres, and polyacrylamide hydrogel for their potential for sustaining bacterial infections and their possible treatments. We were able to culture Pseudomonas aeruginosa, Staphylococcus epidermidisand Probionibacterium acnes in all three gels. When contaminated gels were left for 7 days in a mouse model, we found sustainment of bacterial infection with the permanent gel, less with the semi-permanent gel, and no growth within the temporary gel.
Evaluation of treatment strategies showed that once the bacteria had settled into biofilms within the gels, even successive treatments with high concentrations of relevant antibiotics were not effective.
Our data substantiate bacteria as a cause of adverse reactions reported when using tissue fillers, and the sustainability of these infections appears to depend on longevity of the gel. Most importantly, the infections are resistant to antibiotics once established but can be prevented using prophylactic antibiotics.
The gels can be classified according to their biodegradability into temporary, semi-permanent, or permanent fillers, the latter referring to the lack of degradation of the gel inside the body over time. Biologic materials such as collagen and hyaluronic acid HA gels are easily degraded hydrogels known as temporary fillers.
Fillers consisting of an easily degradable carrier gel and slowly degradable microparticles are classified as semi-permanent fillers. The filling effect stems partially from the degrading poly-L-lactic acid, calcium hydroxylapatite CaHAor dextran microparticles and partially from the growing tissue response, which these microparticles elicit Morhenn et al.
Permanent fillers such as liquid injectable silicone oil, polyacrylamide hydrogel PAAGand polymethylmethacrylate PMMAa combination of nondegradable microspheres suspended in a degradable collagen gel, are nondegradable.
The silicone oil and the polyacrylamide hydrogel contribute to the filling effect by their volume, whereas the nondegradable PMMA microspheres contribute permanently to the filling effect along with the foreign body tissue response, they elicit Morhenn et al.
Adverse events AE to the different filler types have been reported, but their origin has been debated Alijotas-Reig et al. Some have presumed the events to be due to a hypersensitivity inflammatory response to the fillers, whereas others have demonstrated that bacterial infection is the cause of AEs, at least to polyacrylamide gels Christensen et al.
Aggregating bacteria including so-called biofilms have recently received considerable attention. In persistent infections, these play an important role, which can be explained by their increased tolerance toward cells of the immune system and antibiotics Alhede et al. To investigate the role of bacteria — and possible aggregates of these — for the onset of adverse events, we tested three popular fillers, one from each class, in vitro and in vivo. We developed a novel mouse model to test whether low numbers of bacteria could initiate an infection, whether the gels could sustain a bacterial infection, and whether such an infection could be treated with relevant antibiotics.
The bacterial strains used in these studies were tagged with green fluorescence protein GFP. Pseudomonas aeruginosa PAO1; Bjarnsholt et al. A stack of silicone sheets attached to an object glass was used as cultivation chambers for bacteria and gels Table 1. Staphylococcus epidermidis and P. Pseudomonas aeruginosa was not stained as it carries a GFP-tag.
To investigate the bacterial growth and the possible development of biofilms within the soft tissue fillers and their sensitivity to antibiotics, the following three experiments were performed in vitro :.
For the gels meant for late treatment presumed mature biofilms IInew media were added every 24 h. After 72 h, antibiotics or saline The national animal ethics committee, Denmark, approved and authorized all experiments The animal experiments inspectorate, www.
The mice were kept on standard mouse feed and water ad libitum in individually ventilated cage IVC systems Biocenter, Copenhagen, Denmark for at least a week before initiation of the experiments.
The mice were anesthetized by subcutaneous s. Postsurgical the mice were handled as previously described Van Gennip et al. Mice were euthanized with intraperitoneal i. The gel was removed and placed into a sterile 15 mL tube with 2 mL of saline and stored on ice until homogenization with a Silent Crusher M Heidolph, Germany. Homogenization of the samples was carried out for 30—60 s at The homogenization was followed by 5 min of degassing and 5 min of sonication in an ultrasonic bath Branson for disruption of possible bacterial aggregates.
After 6 days of treatment, the mice were euthanized and the gel implants were evaluated for CFUs.

Statistical significance was evaluated by Mann—Whitney test for nonparametric data and one-way analysis of variance anova test with post-test for linear trend for parametric data. If no total clearance was seen in the treatment group, a Wilcoxon signed-rank test nontreated median vs.
The tests were carried out using with prism GraphPad Software.Fillers are commonly used in several aesthetic indications. Though considered safe, several side effects have been reported. The role of biofilms in the causation of some of these side effects has been elucidated only recently and this article presents a short review of the subject.
The concept of biofilm is relatively new to dermatology, though it is a well-established concept in other fields. Recently, it has gained importance as it is often encountered in patients who have received long-term filler implants for aesthetic improvement. This article outlines this concept and its relevance to dermatosurgeons. They are widely distributed in nature. Biofilms can form in different situations in the human body, such as attachment on a surface, or after exposure to sublethal doses of antibiotics.
A biofilm may also form around an infective focus, particularly when a patient is administered inadequate doses of antibiotics.Jansport warranty philippines
While biofilms can contain many different types of microorganisms, e. The various stages during the development of a biofilm have been elucidated and they include,[ 2 ]. The formation of a biofilm begins with the localization, concentration and attachment of free-floating bacteria around a surface which is usually in and around an infective focus.
Biofilms: Their Role in Dermal Fillers
The bacteria get trapped along with cells leucocytes in the EPS, forming microcolonies, which makes them unsusceptible for being attacked by the antibiotics. This matrix protects the cells within it and also facilitates communication among them through biochemical signals.La Era del Biofilm en Odontología Pediátrica, ¿hasta dónde conocemos a nuestros pacientes?
These chemical signals facilitate the distribution of nutrients to the growing bacteria in the biofilm. The final stage of biofilm formation is known as the development phase, in which the biofilm is fully established and may only change in shape and size. Such fully developed bacterial colony ies tends to be antibiotic resistant.
They also secrete bioactive substances which are not produced by the non-aggregated bacteria of the same species. The dispersion of the biofilm may lead to the spread and formation of new colonies. The biofilm can either be dormant or active depending upon the external triggering factor. When the cell metabolism shuts down, it becomes dormant persister. Thus it gets out of reach for antibiotics and also becomes difficult to culture in vitro.
It becomes active following any disturbance in its local environment, such as trauma, injection, manipulation, resulting in manifestations such as local low-grade infection, abscess, local lumps, foreign body granuloma, nodule or systemic infection. The importance of the biofilms to the clinician lies in the fact that they have been implicated in several common infectious processes, such as urinary tract infections, catheter infections, middle-ear infections, formation of dental plaque, gingivitis,[ 5 ] coating contact lenses[ 6 ] and intrauterine devices.
The importance of biofilms to the cutaneous surgeon has been realized only recently. It has been shown that bacterial biofilms may impair cutaneous wound healing and reduce topical antibacterial efficiency in healing or treating infected skin wounds.
The role of biofilms in filler-induced adverse reactions has received increasing attention. Many adverse reactions have been reported after the administration of fillers, such as nodules, abscesses, sinuses, delayed reactions, etc.
Such reactions, though uncommon, may occur, particularly with long acting fillers. They develop within weeks after the administration of the filler, and present as erythematous, mildly tender nodules.
They often persist for months and cause great anxiety to the patient. They are usually culture negative and hence they were previously thought to be due to an allergic or a foreign body reaction to the filler substance. However, supporting data for such an allergic hypothesis have been lacking. These reactions are always small, localized and have no associated antibody formation. Further, many of them resolve with the use of antibiotics.Do you have patients with infections that subside for awhile but then reappear?
Bacterial and fungal biofilms might be to blame. Read on to learn about biofilms and how to treat them. The popular image of bacteria depicts single cells floating around, releasing toxins and damaging the host. However, most bacteria do not exist in this planktonic form in the human body, but rather in sessile communities called biofilms. To form a biofilm, bacteria first adhere to a surface and then generate a polysaccharide matrix that also sequesters calcium, magnesium, iron, or whatever minerals are available.
Since it requires less oxygen and fewer nutrients and alters the pH at the core, the biofilm is a hostile community for most antibiotics. In addition, the biofilm forms a physical barrier that keeps most immune cells from detecting the pathogenic bacteria 12. The current model of care usually assumes acute infections caused by planktonic bacteria.
However, since the vast majority of bacteria are hidden in biofilms, healthcare providers are treating most illnesses ineffectively. According to the NIH, more than 80 percent of human bacterial infections are associated with bacterial biofilm 3.
While planktonic bacteria can become antibiotic resistant through gene mutations, a biofilm is often antibiotic resistant for many reasons—physical, chemical, and genetic. Treating illnesses associated with biofilms using antibiotics is an uphill battle. Biofilms are well-known problems associated with endoscopic procedures, vascular grafts, medical implants, dental prosthetics, and severe dermal wounds.
Biofilms found along the epithelial lining of the nasal passageways and GI tract are less understood. The GI tract is an ideal environment for bacteria, fungi, and associated biofilms because of its huge surface area and constant influx of nutrients 4.
For protection, the GI epithelium is lined with viscoelastic mucus, but it can be damaged in patients with excessive inflammation, IBD, and other conditions. This creates an opportunity for bacteria to attach to the surface and begin their biofilm construction. The epithelium to which it is attached is altered and often damaged 56. Although a culture might come back negative, the microbes in a biofilm could still be pumping out toxins that cause illness.
Some clinicians look for mycotoxins in the urine to identify biofilms 8but I am not impressed by the research behind it yet. Because the bacteria sequester minerals from the host, mineral deficiency is probably associated with the presence of biofilms, although mineral deficiencies are all too common in the general population to use this alone as a diagnostic criterion.
The medical community is increasingly dealing with antibacterial-resistant infections, with evidence of a biofilm at work behind the scenes:. Biofilms have also been implicated in chronic ear infections, chronic fatigue syndrome, multiple sclerosis, and acid reflux 419 Peta Cohena pioneer in treating autism with a biomedical and nutritional approach, has found evidence of biofilms in autistic patients. Autistic individuals often have elevated mercury and lead levels Check out my podcast here for what I believe are underlying causes of autism.
Antibiotic after antibiotic for IBD. Corticosteroids for CRS.One of the most popular procedures of facial fillers in recent years has become the use of hyaluronic acid HA. However, this method may be associated with local side effects of different severity.Psykologisk thriller
Many of them are not due to allergies, as previously believed, but to the formation of biofilm. We review the current knowledge on biofilm after HA. Local infections were reported: 13 cases are attributable to the activation of the biofilm. Clinical evolution is generally mild. Therapy should avoid NSAID and is based on the administration of antibiotics, oral corticosteroids, or 5-Flourouracil. Removal of HA with hyaluronidase has also been proposed. The use of HA in cosmetic procedures might be accompanied by local adverse effects attributable to biofilm formation.
This usually has a mild evolution, but in special cases requires specific therapy. The hyalouronic acid HA became one of the most popular cosmetic procedures, after its approval by FDA in It is used for lip augmentation, scars treatment including acne scars [ 1 ], nasolabial, glabellar, marionette, neck [ 2 ] wrinkles or even in improving the presentation of atopic dermatitis [ 3 ].
HA itself is an important component of the connective tissue that decreases during the aging process. In its natural form, the injectable HA lasts only 24—48 hours, thus the cosmetic product has to be stabilized through biochemical modifications [ 4 ]. This impressive number shows the importance for doctors to know both the benefits and the side effects entailed by cosmetic HA gel, and to increase the awareness of their patients on the potential risks of these injections [ 56 ].
There are several reports on the adverse events of this procedure in the literature, although most of them are minor and temporary. However, some complications can be devastating [ 7 ]. The most common complications include hematoma, allergies, asymmetries, skin necrosis or infections [ 4 ]. A new concept considers that many HA complications are due to biofilms and not due to allergies or other inflammatory response. The biofilms are groups of microorganisms in which cells stick to each other in a three-dimensional structure, on a given surface.
Usually the biofilm is covered by a polymeric substance which offers antibiotic resistance. The biofilms live in dormant state low-grade infectionbut an active infection can be triggered by trauma, hematogenic infection or iatrogenic manipulation.
Because the biofilms are hard to culture and to detect, many HA complications were not correctly diagnosed and were attributed to allergies. The aim of this paper is to review available evidence on the diagnosis and treatment of biofilm formation after HA filler injections. A PubMed database search was performed; cosmetic surgery books were also screened.
The cited references of each article were searched, and those considered relevant were reviewed. Nine different items were followed: etiology, pathophysiology, clinical presentation, diagnostic, differential diagnosis, prognosis, prevention and future directions.
The evidence was not large enough to undertake a systematic review of this issue.Read on!
What are Bacterial Biofilm in Skin Infections?
If you think of bacteria as individual houses, biofilm is the subdivision they build when they want to create a community to make themselves more resilient and likely to survive. They do this by creating an extracellular substance slime made of sugar units that increases their chance of survival against intrusion. Biofilm grows on surfaces like those found in showers and gyms and on objects like kitchen utensils, animal, plant, or human tissue—and even medical devices like pacemakers and joint implants.Www xns tamil sex
However, biofilm can also be invisible to the human eye. Your skin naturally protects you from infection when it is intact. But skin becomes susceptible when an accident or irritation turns into a wound.
Treating Seborrheic Dermatitis Biofilms
Biofilm can cause acne and Staph infections to become chronic issues rather than temporary annoyances. Patients with a severe infection will likely need ongoing antibiotics and other treatments that may take significant time to be effective. If you deal with frequent skin irritations, arm yourself with the knowledge around how to prevent biofilm buildup.
The below three audiences, in particular, should take special care. Athletes If you play a contact sport or any sport that makes you work up a good sweat, thorough hygiene practices are important to protect your skin from infection. Shower within one hour of a workout and keep your clothes and gear clean and dry. If one waits to shower, the small number of bacteria present after a workout can grow from single units to colonies of bacteria that are shielded by a protective slime layer.
Thereafter, they become much harder to remove and can be a breeding ground for bacteria to multiply rapidly. Teenagers and Adults with Oily Skin If you have oily skin, you are more prone to an infection at the hair follicle. Continue with your prescribed plan and arm yourself with effective cleansers, such as CLn BodyWash.Jbl e45bt power button
Also, try as hard as possible not to scratch flares. Resulting abrasions are like throwing the doors wide open at a house party for biofilm. The best course of action for biofilm infection prevention lies in keeping your skin clean and dry.
Look for a cleanser like CLn BodyWash that is tough on microbes, but gentle on skin. CLn BodyWash is a sodium hypochlorite wash created in partnership with dermatologists especially for skin prone to irritations, rashes and infection. CLn SportWash is also recommended for use post-workout even for those without active breaks in the skin.
Another wise move is to think before you share.Late bacterial infections LBIs after esthetic facial augmentation using hyaluronic acid HA fillers are relatively rare yet severe complications that are difficult to treat. No adequate treatment standards have hitherto been formulated. We have bridged this gap by formulating a treatment scheme based on the principles of treating foreign-body implantation-related infections and treating bacterial growth in the form of biofilm.
The objective of this study was to evaluate the efficacy of a comprehensive scheme for treating LBI complications after facial augmentation using cross-linked HA fillers.
A total of 22 patients with LBI symptoms at a site of cross-linked HA injection underwent treatment and observation. To treat LBI at a site of cross-linked HA administration, the principles applicable to infections resulting from implantation of a foreign body must be followed. The treatment period should be sufficiently long for complete resolution of symptoms. The efficacy of treatment is considered proven if 2 months have elapsed without recurrence since the symptoms resolved.
Aesthetic medical procedures involving facial augmentation using hyaluronic acid HA fillers are commonplace and their number is steadily increasing. In the US, the use of fillers soared from 1. Inflammatory swelling or nodules usually emerge several weeks to several years after the procedure.
Treating infections of this kind poses a serious challenge.Wow brownies 300 mg
If appropriate treatment is not provided at the initial stage of infection induration, inflammation, and painfistulae can form, through which pus and degraded filler pour out. In cases of culture-negative pus, some medical practitioners consider the aforementioned symptoms to represent an allergic reaction. Infections complicating procedures involving tissue fillers were included in the scope of the guidelines.
A biofilm is an aggregation of bacterial cells attached to an artificial surface, embedded in a matrix of extracellular bacterial macromolecules. A biofilm, or sedentary microbial amalgam, may consist of one or many strains.
Bacterial cells in a biofilm differ physiologically from planktonic cells free-floating single cells3 including having a significantly lower metabolic rate. The eradication of a biofilm from a solid surface is difficult. The matrix protects the microbes from many externally applied factors, such as bactericides. Its branched system of tubules ensures nutrient transport and communication among microbes via chemical and physical signaling quorum sensing. Bacterial cells in a developed biofilm have a shared set of defensive mechanisms that allow the microbial amalgams to function in conditions in which separate cells would likely die.
Cultivation and identification of bacterial cultures in so altered a state are very difficult.Do you ever use a dandruff shampoo which works perfectly for a period of time? And then it just seems to stop working?
Over the last couple of decades, research has shown that there are fungal conditions that build a tolerance to antifungal treatments over time. Biofilms help to explain why skin conditions such as seborrheic dermatitis are difficult to treat with antibiotics and can persist for months to years.
Research is currently being undertaken to find novel strategies for disrupting biofilms, with a range of promising molecules already identified. Biofilms are complex biological systems, but the idea is relatively simple — that there are evolutionary benefits for microorganisms that grow in communities.
These microorganisms adhere to a surface and produce an extracellular matrix — comprising mostly of carbohydrate polymers — physically protecting against external stressors better than individual cell walls :. Interestingly, microorganisms within a biofilm have been shown to share and express unique genes .
This poses a significant problem for antibiotic therapy, as resistance can quickly transfer within a biofilm — a colony that is already difficult to treat due to the physical protection of the extracellular matrix. While substantial research has been conducted into the biological mechanisms of biofilm formation, resistance, and disruption, many of these studies have been with:.
These studies cannot reliably be extrapolated because the microorganisms are not commonly associated with chronic skin conditions, and the characteristics of a biofilm depend strongly on the species . Although we are at early stages of research in this area, several studies have attempted to evaluate biofilms in dermatitis skin conditions.
A study found that applying a 0. We also know that Malassezia can form biofilms . Some researchers have hypothesized that biofilms. There have been very few studies examining the ability of Malassezia yeasts to form biofilms although this has been demonstrated in some yeasts, particularly Candida. In studies evaluating Malassezia biofilms, no results have yet been of any direct clinical significance. A study showed that Malassezia biofilms exhibit significantly higher resistance to common antifungals e.
In addition, we also know that selenium sulfide is a very effective biofilm-dispersing agent . There have been no clinical trials to date evaluating the effectiveness of different molecules, concentrations, and formulations on the treatment of biofilms associated with skin conditions.
Research into biofilm disruption has identified several promising molecules, worthy of further testing in clinical trials:. Selenium Sulfide, in 2. All are known to disrupt Streptococci, Candida, and P. Erythritol has also been shown to synergistically work with antifungals, better than sorbitol or xylitol [4, 5]. Xylitol is a common additive in chewing gums to help reduce dental plaque the most recognizable biofilm. Wound healing is an important aspect of biofilm research.
Lactoferricin can disrupt biofilms and promote wound healing . When combined with xylitol the antibiotic effects are amplified — with a patent formulating the combination into a petroleum-based cream e.
Aquaphor . Acetic acid and honey are both effective wound dressings, and their effectiveness is possibly in part due to biofilm disruption [9, 10].
Farnesol is used by certain microorganisms to limit the expansion of the extracellular matrix in dense populations. A study showed that when combined with an antibiotic, farnesol was an effective treatment for methicillin-resistant S. Cranberry is known to disrupt the biofilm of E.
Taurolidine is known to eradicate fungal biofilms. A pivotal clinical trial of 51 participants, with long-term intravenous catheters, showed a significant reduction in blood infections when the molecule was used in the locking mechanism — a method now widely adopted .
