An adverse reaction after hyaluronic acid filler application: a case report.

Among several skin fillers developed in recent decades, hyaluronic acid (HA) fillers have become the material of choice. They are safe, long-lasting, not immunogenic, and cost effective, and they can be removed with hyaluronidase. Unfortunately, early and delayed complications can also occur following HA filler injection. Here we report the case of a hyaluronic filler-related complication in a 50-year-old female patient. The locations affected were the forehead, glabella, and nose. Three days after HA fille...

Necrosis of the Glabella After Injection With Hyaluronic Acid Into the Forehead.

Skin necrosis is a rare but severe potential complication after injection of hyaluronic acid (HA). Based on the understanding of the causes and mechanisms of this complication, many precautions have been proposed. Still, this adverse reaction happened from time to time. Here, the authors present a patient with glabellar skin necrosis following an injection into the forehead using HA filler. Although not uncommon, this patient might suggest an alternative cause or mechanism of tissue necrosis following HA in...

Mixing of Injectable Fillers: A National Survey.

The mixing of hyaluronic acid or calcium hydroxylapatite fillers with normal saline, plain lidocaine, or lidocaine with epinephrine before injection is a familiar practice among dermatologists. However, the frequency of this practice and rationale behind it has not been well studied.

Nasolacrimal Duct Obstruction Following Hyaluronic Acid Rejuvenation of the Tear Trough.

Although generally safe, hyaluronic acid rejuvenation of periorbital tissue has been reported to cause minor and major adverse events. The authors document a case of nasolacrimal duct obstruction due to hyaluronic acid rejuvenation of the tear trough. Nasolacrimal duct obstruction immediately resolved following irrigation of hyaluronidase into the affected lacrimal system. To the authors' knowledge, this is the first reported case of nasolacrimal duct obstruction due to filler injection.

Evaluation of the In Vivo Kinetics and Biostimulatory Effects of Subcutaneously Injected Hyaluronic Acid Filler.

Expanding Treatment Options for Injectable Agents.

Loss of facial volume and soft-tissue support are common to types of facial aging. Restoration of a youthful appearance relies upon correction of this loss, and can be achieved in various capacities through use of biostimulatory or hyaluronic acids (HA) injectable fillers. Here, the authors discuss the versatility of calcium hydroxylapatite (CaHA) in volume replacement and the applications and facial regions for which CaHA, poly-L-lactic acid (PLLA), and HA fillers are best suited.

Full-face augmentation using Tissuefill mixed with platelet-rich plasma: "Q.O.Fill".

Hyaluronic acid fillers have become popular soft tissue filler augmentation agents over the past several years. Q.O.Fill (JW Pharmaceutical Co., Ltd., Seoul, Korea) is a newly developed soft tissue augmentation agent using Tissuefill (hyaluronic acid derivatives) mixed with platelet-rich plasma (PRP). The purposes of this study were to describe the Q.O.Fill method and evaluate the outcome of face augmentation.

Evaluation of remineralization potential and mechanical properties of pit and fissure sealants fortified with nano-hydroxyapatite and nano-amorphous calcium phosphate fillers: An study.

The aim of this study was: (i) to formulate pit and fissure sealants (PFS) containing nano-hydroxyapatite (nHAP) filler; nHAP filler and silica co-filler; nHAP and nano-Amorphous Calcium Phosphate (nACP) co-filler, (ii) to evaluate physical properties; degree of conversion (DOC), curing depth (CD) and mechanical properties; microshear bond strength (MBS) of fortified PFS, and (iii) to assess remineralization potential and release of Ca and PO ions from newly synthesized sealants.

A high crosslinking grade of hyaluronic acid found in a dermal filler causing adverse effects.

Facial treatments with dermal fillers for medical or esthetic purposes occasionally give rise to adverse effects, ranging from temporary effects such as reddening of the skin, to long term effects such as hardening of tissue. There appears to be a relationship between the lifetime of the filler product and the risk for adverse effects. The lifetime of hyaluronic acid-based fillers is dependent on the presence and amount of crosslinking agents such as 1,4-butanediol diglycidyl ether (BDDE). It would therefor...

Commentary on: Detailed Sonographic Anatomy of Dorsal Hand Augmentation With Hyaluronic Acid and Calcium Hydroxyapatite Fillers.

Hyaluronic acid-induced capacitation involves protein kinase C and tyrosine kinase activity modulation with a lower oxidative metabolism in cryopreserved bull sperm.

Hyaluronic acid is a glycosaminoglycan present in uterine and oviductal fluids in female ruminants, which has been used as a sperm capacitation inducer prior to in vitro fertilization in several species. CD44 is a specific hyaluronic acid receptor, present in the sperm plasma membrane, but its signaling transduction system has not been elucidated yet. Our aim was to study protein kinase C and tyrosine kinase participation in intracellular signaling and oxidative metabolism in hyaluronic acid-induced capaci...

Lower-Extremity Osteomyelitis Treatment Using Calcium Sulfate/Hydroxyapatite Bone Void Filler with Antibiotics .

Over a 74-month period (∼6 years), 143 lower-extremity osteomyelitis locations in 125 patients were treated with a calcium sulfate/hydroxyapatite liquid bone void filler with antibiotic(s).

Hyaluronic acid surface modified liposomes prepared via orthogonal aminoxy coupling: synthesis of nontoxic aminoxylipids based on symmetrically α-branched fatty acids, preparation of liposomes by microfluidic mixing and targeting to cancer cells expressing CD44.

New synthetic aminoxy lipids are designed and synthesized as building blocks for the formulation of functionalised nanoliposomes by microfluidisation using a NanoAssemblr®. Orthogonal binding of hyaluronic acid onto the outer surface of functionalised nanoliposomes via aminoxy coupling (N-oxy ligation) is achieved at hemiacetal function of hyaluronic acid and the structure of hyaluronic acid-liposomes is visualised by transmission electron microscopy and cryo- transmission electron microscopy. Observed str...

Detailed Sonographic Anatomy of Dorsal Hand Augmentation With Hyaluronidase and Calcium Hydroxyapatite Fillers.

Volume restoration using filler in the dorsum of the hand is a simple and effective procedure to improve wrinkles and to hide veins and tendons. Currently, Calcium-Hydroxyapatite (CaHA)-filler is the only FDA-accepted material to use in the hand dorsum. However, it is not easy to inject due to swelling and redness. In addition, hand anatomy through sonography is wrongly described in PRS. Through incorrect anatomy, physicians will make erroneous surgeries.

Ocular and cerebral infarction from periocular filler injection.

A 20-year-old woman presented with loss of vision in her right eye and a "black nose" after receiving hyaluronic acid filler injections in her right glabella 1 month prior. Her vision was no light perception, and external examination revealed resolving skin necrosis at the nasal tip. A dilated fundus exam showed a fibrotic membrane emanating from a pale optic nerve and a diffusely atrophic retina with sclerotic vessels. An MRI demonstrated scattered right-sided parietal lobe infarcts. These findings were c...

Hyaluronic acid (HA) injection is a popular nonsurgical, facial rejuvenating procedure. Due to the rapidly expanding use of HA injections, significant potential complications have also increased in frequency. Among these complications, the rare but most devastating one is arterial occlusion, which can result in skin necrosis or blindness. To describe the mechanisms behind vision loss secondary to hyaluronic acid injection and the efficacy of treatments to restore vision and associated ocular functionality. ...

Modification of cysteine 179 in IKKβ by ursolic acid inhibits titanium wear particles-induced inflammation, osteoclastogenesis and hydroxylapatite resorption.

Aseptic loosening of artificial joint mainly accounts for the failure of arthroplasty. We previously reported that ursolic acid inhibited titanium particle-induced osteolysis via suppression of NF-kB signaling. In this study, we demonstrated that the inhibitory effect of UA on Ti particle-induced inflammation and osteoclastogenesis targets on IKKβ cys-179. A retrovirus packaged IKKβC179A plasmid with mutation of Cys-179 replaced by Ala was constructed. RT-PCR, western blot, and Immunofluorescence were per...
