The efficacy of hyaluronic acid fragments with amino acid in combating facial skin aging: an ultrasound and histological study.

BACKGROUND: Various techniques have been employed in aesthetic medicine to combat skin aging, in particular that of the facial region. Hyaluronic acid is utilized to enhance moisture levels and extracellular matrix molecules. This study aims to histologically assess the effects of low molecular weight hyaluronic acid fragments combined with amino acids (HAAM) on facial skin rejuvenation through intradermal microinjections. METHODS: A total of twenty women, with an average age of 45 and ranging from 35 to 64 years old, participated in the study, including 8 in menopause and 12 in the childbearing age group. Mesotherapy was used to administer HAAM to the patients. Prior to and three months after the treatment, each patient underwent small circular punch biopsies. Ultrasound examinations were conducted using B-mode, capturing 2D images in longitudinal or transverse orientations with frequencies ranging from 5 to 13 Mega-hertz (MY LAB X8, ESAOTE, Genova, Italy). A total of 60 ultrasound examinations were taken, with 30 collected before treatment and 30 after treatment. RESULTS: The histological analysis demonstrates an increase in fibroblast activity resulting in the production of Type III reticular collagen, as well as an increased number of blood vessels and epidermal thickness. However, the analysis of ultrasound data before and after treatment showed no statistical difference in skin thickness in malar area, chin and mandibular angle. CONCLUSIONS: Histological assessments indicate that subcutaneous infiltration of HAAM has a substantial impact on the dermis of facial skin.

Reduction of double chin without surgery using ascorbic acid and ascorbyl-palmitate solution: a clinical study.

OBJECTIVE: The purpose of the present clinical study is to assess the effectiveness of a lipolytic solution containing sodium salt of ascorbic acid at 0.24% and a surfactant agent at 0.020% ascorbyl-palmitate (SAP) for the treatment of double chin. PATIENTS AND METHODS: A total of 10 healthy adult subjects affected by double chin (8 female and 2 male) were evaluated in the present investigation. The patients were admitted to a total of 4 sessions, with biweekly procedures, without no other active agents addiction. RESULTS: In all the subjects a reduction of the convexity of the chin after the treatment with SAP was observed. Improvement in submental appearance was achieved in 90% (9/10) of the patients. One patient did not see any improvement in submental appearance after two section treatments and withdrew from the treatment. CONCLUSIONS: In conclusion, in the present study, a new adipocytolytic solution consisting of sodium ascorbate mixed with ascorbyl-palmitate was used with success as a surfactant agent for the treatment of double chin.

Chronic lip edema and pain secondary to lip augmentation procedure: histological, scanning electron microscopy and X-ray microanalysis evaluation.

BACKGROUND: In parallel with the increase in requests for filler injections, reported complications (immediate or delayed and transient or permanent) increased too. CASE REPORT: In the presented case report, a patient reported a delayed complication of filler injection. The complaints of the patient and the objective evaluation revealed the presence of multiple lip nodules, that were painful both spontaneously and at the touch, after 10 years from a lip filler injection. The surgical excision of the neoformations permitted the complete healing of the lesions. The histological analysis showed a not specific pattern, showing a material encapsulated by a tissue reaction, confirming that the possible cause of the multiple injuries could be attributable to the injection received years earlier. CONCLUSIONS: The professional who intends to perform filler injections needs a complete training process, both from a theoretical and practical point of view. Also, the patients must be informed of the possible risks associated with each product.

Histological aspects of cellulite: shedding light on 100 years of uncertainties.

Cellulite is a common topographic condition of the skin manifested as lumpy, dimpled flesh resembling an orange peel on some zones such as the thighs, hips, buttocks and abdomen. The aetiology of this cosmetic issue is multifactorial, with hormonal, anatomical, environmental and genetic factors influencing its origin, although the exact mechanisms which cause this condition are still unknown. In the present work, a bibliographic analysis of the cellulite etiology has been updated and exposed, as well as the multiple classification grade scales established over the decades. In addition, a new method to classify cellulite severity, in which the clinical manifestations are correlated to the histological aspects more frequently found in the patients, has been presented. Several theories regarding its appearance, structure and clinical aspects have arisen with the aim of developing and establishing a valuable therapeutic approach. However, the lack of a consensus regarding the classification of cellulite severity has complicated the developments within this field.

Evaluation of the efficacy and safety of hyaluronic acid and supplemented with amino acids, and glutathione or colin, for the prevention and treatment of wrinkles on the face, neck, décolleté and hands.

OBJECTIVE: Hyaluronic acid has been used for a long time as a biorevitalizer to treat skin aging both in single formulation and in association with other compounds such as amino acids or vitamins. The purpose of this study was to evaluate the efficacy and safety of class III medical devices SKIN B, SKIN R, SKIN OX, SKIN COLIN, for the treatment of wrinkles on the face, neck, décolleté and hands. These medical devices are all based on hyaluronic acid and supplemented with amino acids (SKIN B and SKIN R) and glutathione (SKIN OX) or colin (SKIN COLIN). This gives broader possibilities to the aesthetic surgeon for personalization and pharmacological diversification based on the patient's deficits to treat. PATIENTS AND METHODS: A total of 60 subjects affected by skin damage such as rhytidids, dehydration, reduced sebum production and skin hypoxia were enrolled. The patients were treated with a session of mesotherapy every 7 days for 30 days, followed by other 2 sessions every 15 days for 30 days and the follow-up on day 90. The primary efficacy endpoint was evaluated by means of a 0-10 visual analog scale at day 60; the secondary efficacy endpoint was evaluated by means of a 0-10 visual analog scale at day 90. RESULTS: All patients completed the 3-month follow-up. Treatment with SKIN B, SKIN OX, SKIN COLIN and SKIN R medical devices for the prevention and treatment of wrinkles on the face, neck, décolleté and hands were associated with favorable and positive results. A clear reduction of wrinkles has been clinically observed with improvement in the texture, brightness, and turgor of the skin. No adverse events were reported. CONCLUSIONS: The medical devices SKIN B, SKIN SKIN OX, SKIN COLIN produce an aesthetic improvement in patients affected by skin defects, when administered by mesotherapy technique. This study confirms the safety and efficacy of the medical devices based on hyaluronic acid supplemented with amino acids and glutathione or colin.

Malar augmentation with Hyaluronic acid enriched with glycine and proline: a clinical evaluation.

The aging process causes skin modification and wrinkle formation with an alteration of the face harmony and imperfections. The aim of the present investigation was to evaluate a cross-linked hyaluronic acid enriched with glycine and proline for zygomatic malar region infiltrations. A total of twenty healthy female patients were treated for zygomatic hypotonia. The level of patients and surgeon satisfaction was evaluated by global aesthetic improvement scale (GAIS) at baseline, immediately after the procedure and at 6 months from the treatment. The healing phase was uneventful, and no complications were reported in the perioperative and follow-up periods. No significant differences were reported between patients and surgeon GAIS score (p<0.05). A significant difference of GAIS score was reported immediately after the procedure and at 6 months if compared to the baseline (p<0.05). The cross-linked hyaluronic acid enriched with glycine and proline is a useful biomaterial for zygomatic- malar augmentation with no significant local complications and a high stability and satisfaction level of the procedure.

Clinical evaluation of efficacy and tolerance of a skin reconditioning compound for anti-aging.

Facial aging involves all facial structures located at different levels: bones soft tissues and skin with a reduction of the extracellular matrix. The aim of the study was to evaluate the efficacy of the injectable solution antiaging complex composed by non-reticulated hyaluronic acid (HA) and amino acids vitamins and antioxidants conveyed with mesotherapy technique in subjects with different expressions of aging. 114 patients with different expressions of aging were enrolled in this study with mean age (49±6). HA and amino acids vitamins and antioxidants complex solution Neofound (Love Cosmedical, Castagneto, Italy) was injected on the dermal plane or superficial subdermal plane. Among the various imperfections, fine roughness surface irregularities skin firmness brightness/discoloration cutaneous hydration were those with the greatest response to therapy. The clinical data showed that the medical device Neofound is effective and safe to treat various skin signs of chrono and photoaging thanks to its ability to protect tissues from oxidative stress and hydrate the skin.

Hyaluronic acid fillers in lip augmentation procedure: a clinical and histological study.

Several approaches have been proposed for soft tissue augmentation using injectable materials for lip and soft-tissue augmentation due to their physical and biological properties. Hyaluronic acid represents a natural component of the connective tissues, related to wound healing and skin regeneration. The aim of this research was to investigate the clinical and histological effectiveness of cross-linked hyaluronic acid for lip augmentation. A total of 8 patients were treated for lip augmentation with a clinical follow up of 60 days. After this period a histological evaluation was performed to evaluate the healing of the treated regions. The healing phase reported no inflammatory response, tissue contractions and no local flogistic evidence in the treated areas, where the filling volume appeared maintained. The 60 days histological evaluation showed evidence of filler resorption with few infiltrated inflammatory cells. The clinical and histological findings suggested that cross-linked hyaluronic acid represents a safe and effective tool for lip augmentation.

Cortical bone lamina approach for mandibular large cystic defect: a case report.

This study evaluated the bone healing of the residual cavity after enucleation of mandibular inflammatory cyst by using only a coverage with cortical bone barrier. This study was conducted at the dental clinic of the Medical, Oral and Biotechnology Sciences Department of Chieti in February 2015. A 36-year-old male patient, D.G.M., had a mandibular inflammatory cyst (with a diameter of about 33.9x20.3mm) treated by surgical enucleation, subsequent apicectomy of the elements involved (4.1, 3.1, 3.2, 3.3, 3.4) and coverage of residual defect with a porcine cortical bone barrier (Bone Lamina). Postoperative clinical and radiographic examinations were performed at 3 and 9 months (panoramic radiographs) and at 12 and 24 months (CBCT Dental scan) respectively after cystic enucleation surgery. Uneventful healing and filling of the residual cavity was carried out. The computed analysis of the postoperative radiographs showed bone regeneration of cortical in terms of thickness increase at 12 and 24 months and showed mean values of reduction in size of the residual cavity of 92.1% after 12 months and 96.53% after 24 months. The volume of residual cavity (3123 mm3 in 2015) was seen to decrease (243.6mm3 at 12 months and 108.5 mm3 at 24 months). In this case report the Bone Lamina prevented tissue collapse within the defect and could maintain structural integrity throughout the period required for bone regeneration; it also has the advantage of resorbable membranes, avoiding a second surgery for its removal.

Evaluation of the effectiveness and safety of peppermint peel (PMP) soft peeling for skin ageing.

Turning to peeling in a dermatological sphere is extensively common and has been used for a long time. From the use of single acids moving on to the so-called compound peelings (associations of more than one substance in the same product) and the combined peelings which take advantage of the action of different substances in a synergistic manner (different products are applied sequentially) in order to best guarantee a greater effectiveness of the treatment for the recommended target. Superficial peelings, combined and not, have led to a drastic reduction in the percentage of incidence of adverse events typical of medium and deep peels. Nevertheless, it has been demonstrated that superficial peels bring about a rejuvenating effect through the mechanical stimulation of the Skin Stress Response System (SSRS), system designated to repairing the damaged tissue and restoring of the normal homeostasis. Clinical trials aims to evaluate the effectiveness and safety of the peppermint peel (PMP) medical device in subjects with different ageing expressions both in qualitative terms (different blemishes such as discolouration, fine wrinkles, elastosis, atony and skin inelasticity, laxity, scarce superficial hydration) and in quantitative terms (degree, extension and number of lesions). A non-controlled multi-centric clinical trial was done in 121 subjects. The use protocol calls for a session every 2 weeks for a total of 4 sessions. Subjects were evaluated before each subsequent session at the first and at 2-4-8 weeks of the fourth and last treatment. During the study there were no adverse events. Only a minimal scurfy flaking and a very slight redness were reported. From an effectiveness point of view, the percentage of therapeutic failure, judged with a score equal to or greater than 4 or 5 in Global Aesthetic Improvement Scale (GAIS) scale was 0%. Best score was obtained in subjects ranging in ages between 38 and 57 (2.02) and in women (2.02) years, while the less satisfactory one was obtained in males (2.14). The study has demonstrated that PMP and the proposed protocol are effective and safe to treat subject with skin signs of chrono and photo ageing, thanks to its capabilities of carrying out a mechanic action indicated as a coadjuvant in the treatment of the dermoepidermic revitalisation through chemical exfoliation and hydration.

Non-surgical treatment of lower eyelid fat pads with an injectable solution acid deoxycholic based.

The use of sodium deoxycholate (DC) in aesthetic medicine for reducing unwanted localized fat deposits is a procedure in use for over 30 years. Lower eyelid fat pads are one of the main imperfections of the middle third of the face. The purpose of the study is to assess the effectiveness and the safety of a second-generation injectable solution containing sodium deoxycholate 1.25% (DB125) for the treatment of lower eyelid fat pads. A multi-centre observational prospective study was carried out between May and October 2017. Patients presented various forms and degrees of lower eyelid fat pads. They were treated montly apart until the clinical result was obtained. The technique was explained. The study treated 120 patients for a total of 306 infiltration sessions (average 2.55 per patient). Patients gave the effectiveness of the treatment an average score of 7.125 (7.28 in men and 7.03 in women). The greatest successes were in patients under the age of 40. The medical evaluation showed therapeutic success in 85.83%. Adverse events were reported. The results of the study are encouraging since they have shown a therapeutic success from both the viewpoint of specialist medical assessment and from the personal, subjective view of the patients treated. This success did not show any significant differences between sex. On the other hand, outcome has been better in the younger age groups. The high degree of effectiveness shown in the study was associated with a minimal occurrence of adverse events. Therefore DB125, used with the right technique and dosage, is effective and safe to treat lower eyelid fat pads.

[Primary lymphoma of the breast. Three cases of non-Hodgkin lymphoma]. / Il linfoma primitivo della mammella. A proposito di 3 casi di linfoma non-Hodgkin.

Primary and sole breast lymphoma is a very rare disease. With the review of our series of 616 cases operated on for breast cancer, only 3 cases (0.48%) of primary breast non-Hodgkin lymphoma (LNH) have been observed. The authors outline the problems concerning diagnosis and therapy of this rare disease: pathological and immunohistochemical aspects are discussed. They stress the importance of staging in order to plan a correct multidisciplinary approach.

[Our experience in the surgical treatment of early breast cancer. Results of a prospective study of 204 cases]. / La nostra esperienza nel trattamento chirurgico del carcinoma mammario iniziale. Risultati di uno studio prospettico su 204 casi.

The authors report the results of a prospective study on 204 patients (1980-1993) affected by early infiltrating breast cancer (size pounds 2 cm) as a part of a surgical series of 608 cases. 53 cases who underwent QUART (25.9%) and 151 cases (74.1%) who underwent mastectomy modified according to Patey have been collected. 10 years actuarial survival has been respectively 79% after extensive surgery and 78% after conservative treatment. Local recurrences have been observed in 9 cases after meticulous follow-up (median 74.8 months, range 12-178): 3 (5.66%) patients after QUART and 6 (3.97%) after mastectomy; furthermore 1 patients after a conservative treatment (1.88%) has developed a second tumor at the same side probably dependent on the presence in the primary tumor of an extensive intraductal component. No correlations between histological features, grading, positive nodes, receptor status and local recurrences have been found. Only the age of patients looks significantly correlated with frequency of recurrences: 44.45% of local recurrences have been observed in patients less than 45 years old. Local recurrences after QUART have obliged, in all cases, to a radical mastectomy. Furthermore, frequency of distant metastases has been considered: after QUART percentage is lower (9.43%) than after radical mastectomy (13.9%). This consideration looks correlated with the longer follow-up of the later group. A multidisciplinary approach is advised but the most important role is played by surgery. In conclusion it is outlined that conservative surgery is addressed to selection and consenting patients.

[Natural history of breast cancer: lobular carcinoma versus ductal carcinoma in our experience]. / A proposito della storia naturale del cancro della mammella: carcinoma lobulare versus carcinoma duttale nella nostra esperienza.

Aim of the study is to evaluate the biology, the clinical evolution and the prognosis of lobular carcinoma of the breast. We retrospectively evaluated the patients treated in our institution during the last 13 years. 117 patients with lobular carcinoma of the breast and 117 patients, randomized out of 397 patients with 'classical' pattern of ductal carcinoma were compared. Age distribution, type of surgery, tumor size, TNM stage, axillary lymph node involvement, multifocality, multiple breast cancers, local and distant recurrences, overall survival and disease-free survival have been evaluated. There was not a significant difference in tumor size, lymph node involvement, stage distribution, estrogens and progesterone receptors status, local and distant recurrences. The only significant differences were found in multifocality and multiple breast cancers. The said difference does not seem to modify the overall survival and the disease-free survival that are the same in the two groups. Our research shows that tumor size and axillary lymph node status are the only elements that have to be considered in the choice of the surgical treatment and prognosis. It seems that the difference in distant metastatic pattern between lobular and ductal carcinoma is the distinctive feature in the follow-up of these patients.
