A randomized, evaluator-blind, multicenter comparison of the efficacy and tolerability of Perlane versus Zyplast in the correction of nasolabial folds.
Bovine collagen is widely used as a dermal filler for facial soft-tissue augmentation, but it provides only temporary cosmetic improvement. Nonanimal stabilized hyaluronic acid has reduced potential for immunogenicity and hypersensitivity a…
- The use of hyaluronidase to reverse the effects of hyaluronic acid filler.

[Aesthetic dermatology. Botulinumtoxin A and soft tissue augmentation].
Younger and younger patients are undergoing aesthetic procedures to achieve "wrinkle-free" aging. This has had great impact on the field of aesthetic dermatology. The rapid development of new indications and filler materials requires a crit…

Hylaform: a new hyaluronic acid filler.
Hylaform is a new facial filler composed of hyaluronic acid. Hylaform is derived from an avian source, and is a clear gel substance. Skin testing is not necessary, although rare allergic reactions can occur form the avian protein content. H…

Migration studies and histology of injectable microspheres of different sizes in mice.
Injectable dermal filler materials consist of either fluids, biological fragments, or suspensions of particles or microspheres. Particles and microspheres are said to "migrate," but migration can occur only when they are injected into blood…

Soft tissue augmentation--use of hyaluronic acid as dermal filler.
Soft tissue augmentation has revolutionized the treatment of the aging face. It is a technique in which a substance is injected under the skin. The concept of utilizing materials for soft tissue augmentation actually began around 1950 with …

Advantages of the presence of living dermal fibroblasts within restylane for soft tissue augmentation.
For the elimination of facial wrinkles and skin contour defects, injectable filler substances composed of commercially prepared nonanimal stabilized hyaluronic acid (Restylane) are now widely used. Although this method of suspension has bee…

Infection and chemotherapy: recent experiences, proposed strategies and perspectives in plastic and reconstructive surgery.
In plastic surgery the necessity of avoiding as much septic complication as possible is caused by major technical peculiarities. On the one hand the use of autologous grafts (skin, cartilage, bone, microsurgical flaps, etc.) makes the surgi…

Pathways of heterocyclic amine activation in the breast: DNA adducts of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) formed by peroxidases and in human mammary epithelial cells and fibroblasts.
Most human mammary carcinomas originate in the epithelial cells of the breast ducts. A potential role of heterocyclic amines (HAs) in the aetiology of this disease has led us to investigate peroxidase-catalysed and stromal (non-epithelial) …

Restoration of the anophthalmic socket with secondary implantation of a coralline hydroxyapatite sphere.
[BACKGROUND AND OBJECTIVE] Restoration of the anophthalmic socket to improve the aesthetic result on the face. [PATIENTS AND METHODS] The authors describe variations in the technique of secondary orbital implantation in 10 patients using t…

[The combined use of hydroxyapatite-based ceramic implants and fixation devices made of titanium in reconstructive operations on the maxillofacial area].
Discusses the possibility of using dense unresorbable hydroxyapatite (HA) ceramics as synthetic osteoplastic material. Analyzes the results of follow-up of 11 patients with congenital and posttraumatic deformations of the facial skull. Inte…

Local increase in hyaluronic acid and interleukin-2 in the capsules surrounding silicone breast implants.
Connective tissue disease-like illness has been associated with silicone breast implants. However, no data are currently available on the immunopathology of the capsule surrounding the breast implants. Sera from women with breast implants w…

Clinical, histopathological, immunological and fibroblast studies in 30 patients with subcutaneous injections of modelants including silicone and mineral oils.
[OBJECTIVE] To study patients with side effects secondary to the injection of modelants. [METHODS] We studied their clinical, serological, histopathological, radiographic, immunoregulatory and fibroblast culture features by standard method…

Upregulation of estradiol C16 alpha-hydroxylation in human breast tissue: a potential biomarker of breast cancer risk.
[BACKGROUND] The biotransformation of the natural estrogen 17 beta-estradiol (E2) via the C16 alpha-hydroxylation pathway is elevated in patients with breast cancer, in subjects at increased risk for developing breast cancer, and in c-Ha-ra…

The use of particulate hydroxyapatite and plaster of Paris in aesthetic and reconstructive surgery.
The authors describe their early investigative results of using a mixture of hydroxyapatite (HA) and plaster of Paris (PP) in skull and frontal sinus defects in a large series of cats. Histologically, bone was found to form and infiltrate t…

Subperiosteal versus epiperiosteal forehead augmentation with hydroxylapatite for aesthetic facial contouring: experimental animal investigation and clinical application.
The difference between periosteal and subperiosteal application of hydroxylapatite (HA) in aesthetic forehead augmentation in the subimplant bed was investigated in six adult Göttingen minipigs. These results were then transferred to clinic…

Expression of c-myc, c-Ha-ras1, and c-erbB-2 proto-oncogenes in normal and malignant human breast epithelial cells.
Short-term cultures of normal human mammary epithelial cells were used to determine the extent to which c-myc, c-Ha-ras1, and c-erbB-2 proto-oncogenes were expressed in proliferating normal cells. This level of expression was compared with …

Transforming growth factor alpha production and epidermal growth factor receptor expression in normal and oncogene transformed human mammary epithelial cells.
We have characterized the expression of transforming growth factor alpha (TGF alpha) and its receptor, the epidermal growth factor receptor (EGF-R), in normal and malignantly transformed human mammary epithelial cells. Human mammary epithel…

Hydroxylapatite as a bone graft substitute in orthognathic surgery: histologic and histometric findings.
The use of porous hydroxylapatite (HA) as a substitute for bone in grafting associated with orthognathic surgical procedures was studied histologically and histometrically. The surgical procedures included maxillary downgrafting, advancemen…
