New trends in breast reconstructive surgery: "Florentine Lily" reductive mastoplasty

BACKGROUND

To describe a mammoplasty technique that we called "Florentine Lily" because of the shape of the pre-operative drawings similarity with the symbol lily Florentine.

METHODS

In a group of 190 women who underwent reductive mammoplasty, 23 women affected by severe enlarged breasts were selected. Main selection requirements were: 18-30 cm rising of the Areola-Nipple Complex (NAC).

RESULTS

to obtain a functional and cosmetic result; preservation of mammary gland function; vitality of the areola-nipple complex and its sensitivity. We describe the case of 35 years old woman affected by severe enlargement of the breast and no pathologies.

CONCLUSION

We didn't observe necrosis of the skin flaps and NAC in any case. In one case (rising of Nipple-Areola Complex >25 cm) NAC showed NAC 2 days post-surgery, which spontaneously resolved. Minor complications (edema and ematoma) developed in 20 cases. No infections were observed.

Mechanical Purification of Lipofilling: The Relationship Between Cell Yield, Cell Growth, and Fat Volume Maintenance

BACKGROUND

The mechanical manipulations of fat tissue represented from centrifugation, filtration, washing, and fragmentation were considered the most effective strategies aiming to obtain purified lipofilling with different impacts both in terms of adipose-derived stem cells amount contained in stromal vascular fraction, and fat volume maintenance.

OBJECTIVES

The present work aimed to report results in fat volume maintenance obtained by lipofilling purification based on the combined use of washing and filtration, in a clinical study, and to deeply investigate the adipose-derived stem cells yield and growth capacity of the different stromal vascular fraction extraction techniques with an in vitro approach.

METHODS

A preliminary prospective, case-control study was conducted. 20 patients affected by face and breast soft tissue defects were treated with lipofilling and divided into two groups: n = 10 patients (study group) were treated with lipofilling obtained by washing and filtration procedures, while n = 10 (control group) were treated with lipofilling obtained by centrifugation according to the Coleman technique. 6 months after the lipofilling, the volume maintenance percentage was analyzed by clinical picture and magnetic resonance imaging comparisons. Additionally, extracted stromal vascular fraction cells were also in vitro analyzed in terms of adipose-derived stem cell yield and growth capacity.

RESULTS

A 69% ± 5.0% maintenance of fat volume after 6 months was observed in the study group, compared with 44% ± 5.5% in the control group. Moreover, the cellular yield of the control group resulted in 267,000 ± 94,107 adipose-derived stem cells/mL, while the study group resulted in 528,895 ± 115,853 adipose-derived stem cells /mL, with a p-value = 0.1805. Interestingly, the study group showed a fold increase in cell growth of 6758 ± 0.7122, while the control group resulted in 3888 ± 0.3078, with a p < 0.05 (p = 0.0122).

CONCLUSIONS

The comparison of both groups indicated that washing and filtration were a better efficient system in lipofilling preparation, compared to centrifugation, both in terms of volume maintenance and adipose-derived stem cell growth ability.

Use of Platelet Rich Plasma and Hyaluronic Acid in the Treatment of Complications of Achilles Tendon Reconstruction

BACKGROUND

The platelet-rich plasma (PRP) and hyaluronic acid (HA) constitute a system of tissue growth that can regenerate damaged tissue. This study was performed to evaluate the effect of PRP and HA in treatment of complications of Achilles tendon reconstruction.

METHODS

We selected ten patients affected by Achilles tendon injuries resulting from post-surgical complications subsequent to tenorrhaphy and have treated them with autologous PRP in combination with HA to evaluate the improvement of lesions with wound closure.

RESULTS

The treatment with PRP and HA for post-surgical complications of Achilles tendon was effective in healing and regeneration of soft and hard tissues. The healing time was shortened, and the treated area preserved a satisfying strength in plantar flexion and extension of the ankle, denoting to a decisive improvement in texture and a more rapid healing and a good cutaneous elasticity, with a significant reduction of the costs of hospitalization and the pain already the immediate postoperatively. The functional rehabilitation in terms of deambulation and joint mobility was complete.

CONCLUSION

The treatment we proposed allowed an easier and more rapid wound closure with excellent aesthetic improvement. Furthermore, the minimally invasive technique is well tolerated by patients.

Hair regrowth treatment efficacy and resistance in androgenetic alopecia: A systematic review and continuous Bayesian network meta-analysis

BACKGROUND

Androgenetic alopecia (AGA) affects almost half the population, and several treatments intending to regenerate a normal scalp hair phenotype are used. This is the first study comparing treatment efficacy response and resistance using standardized continuous outcomes.

OBJECTIVE

To systematically compare the relative efficacy of treatments used for terminal hair (TH) regrowth in women and men with AGA.

METHODS

A systematic literature review was conducted (from inception to August 11, 2021) to identify randomized, Placebo-controlled trials with ≥ 20 patients and reporting changes in TH density after 24 weeks. Efficacy was analyzed by sex at 12 and 24 weeks using Bayesian network meta-analysis (B-NMA) and compared to frequentist and continuous outcomes profiles.

RESULTS

The search identified 2,314 unique articles. Ninety-eight were included for full-text review, and 17 articles met the inclusion criteria for data extraction and analyses. Eligible treatments included ALRV5XR, Dutasteride 0.5 mg/day, Finasteride 1 mg/day, low-level laser comb treatment (LLLT), Minoxidil 2% and 5%, Nutrafol, and Viviscal. At 24 weeks, the B-NMA regrowth efficacy in TH/cm2 and significance (**) in women were ALRV5XR: 30.09**, LLLT: 16.62**, Minoxidil 2%: 12.13**, Minoxidil 5%: 10.82**, and Nutrafol: 7.32**, and in men; ALRV5XR: 21.03**, LLLT: 18.75**, Dutasteride: 18.37**, Viviscal: 13.23, Minoxidil 5%: 13.13**, Finasteride: 12.38, and Minoxidil 2%: 10.54. Two distinct TH regrowth response profiles were found; Continuous: ALRV5XR regrowth rates were linear in men and accelerated in women; Resistant: after 12 weeks, LLLT, Nutrafol, and Viviscal regrowth rates attenuated while Dutasteride and Finasteride plateaued; Minoxidil 2% and 5% lost some regrowth. There were no statistical differences for the same treatment between women and men. B-NMA provided more accurate, statistically relevant, and conservative results than the frequentist-NMA.

CONCLUSION

Some TH regrowth can be expected from most AGA treatments with less variability in women than men. Responses to drug treatments were rapid, showing strong early efficacy followed by the greatest resistance effects from flatlining to loss of regrowth after 12-16 weeks. Finasteride, Minoxidil 2% and Viviscal in men were not statistically different from Placebo. LLLT appeared more efficacious than pharmaceuticals. The natural product formulation ALRV5XR showed better efficacy in all tested parameters without signs of treatment resistance (see Graphical abstract).

AI-enhanced "Two-thirds Guidelines" for Lipolifting: Addressing Multiple Hallmarks of Facial Aging

BACKGROUND

Facial aging involves complex changes such as volume loss, ligament weakening, and skin quality alterations. The "two-thirds guidelines" emerge as a novel strategy to combat these aging signs, drawing from an extensive analysis of 2800 facial fat grafting procedures conducted over two decades.

METHODS

Guided by facial lipolifting data, including patient age, fat type (microfat and nanofat), and injection depth, this study devises a systematic framework for multilayer fat rejuvenation and ligament restoration. The two-thirds guidelines advocate injecting two-thirds of the patient's age for microfat and one-third for nanofat, with specific injection codes for lower, middle, and upper facial regions.

RESULTS

A prospective study involving 400 patients confirms the efficacy of the two-thirds guidelines. However, applicability may vary for patients outside SD ranges, particularly concerning facial proportions and body mass index. Patients within the golden ratio range (1.4-1.9) report high satisfaction rates and a 50% fat graft uptake, with minimal complications. For patients outside this range, an artificial intelligence (AI) program was implemented.

CONCLUSIONS

The two-thirds guidelines offer a comprehensive approach to facial rejuvenation, addressing volume loss, ligament weakening, and skin quality. They are applicable in early aging stages, promising enduring and natural outcomes while mitigating effects of weight fluctuations. These guidelines provide a safe, replicable, and adaptable approach to facial fat grafting, either standalone or in combination with facelift techniques, with minimized overfilling risks. A dataset obtained from 2800 patients serves as the foundation for developing an AI program tailored to aid doctors in diagnosing and treating similar cases.

Ultrapulsed fractional CO2 laser for the treatment of post-traumatic and pathological scars

BACKGROUND AND OBJECTIVE

Scar management is a long-term process. A variety of modalities have been employed and, depending on scar type, treatment may be invasive and/or conservative. The purpose of this study was to evaluate a new CO2 laser resurfacing for post-traumatic and pathological scars and to compare this device with classic dermabrasion. The new fractionated ultrapulsed CO2 laser (Ultrapulse Encore, Lumenis Ltd., Santa Clara, CA) is equipped with two types of scanners: the first, ActiveFX, is non-sequential while the second, DeepFX, is sequential and produces microspot.

MATERIALS AND METHODS

From September 2008 to November 2008, a study on 60 patients was performed. The patients (average age 47.3 years) enrolled in this study had severely scarred skin and were divided into two groups of 30 people. All patients were Caucasian with skin type II or III. Each scar was photographed and scored by the authors using the Manchester Scar Scale (MSS). Follow-up ranged from 12-15 months.

RESULTS

Sixty patients were analyzed in two homogeneous groups. Significant improvement in skin tone, texture and appearance of skin was noted in all patients treated with CO2 laser, lower improvement resulted with dermabrasion. Both subjects and investigators noted similar aesthetic improvement. No major complications were found for both groups and minor complications included transient erythema and edema.

CONCLUSION

Fractional ultrapulsed CO2 laser resurfacing has proven to be both safe and effective. The efficacy and favorable side effects profile for this technology, with low incidence of pigmentary changes, make it a viable alternative for the treatment of moderate-to-severe scars.

Modified peri-areolar mastopexy and fat grafting in complex breast ptosis: A randomized open-label controlled trial

BACKGROUND

Complex breast ptosis may be caused by moderate to severe degrees of skin and glandular sagging associated with breast and nipple-areola complex (NAC) asymmetries and deformities. The use of traditional peri-areolar mastopexy (t-PM) with or without implants is limited only to mild or moderate breast ptosis.

OBJECTIVES

This study aimed to report the safety and efficacy of the modified peri-areolar mastopexy (m-PM) characterized by a vertical shift of the classical pattern with implants and fat grafting (FG) in complex breast ptosis and to evaluate the influence of breast and NAC asymmetries, breast, and chest deformities on aesthetics outcomes.

METHODS

An open-label randomized controlled trial was performed. Forty women (study group - SG) affected by breast ptosis (moderate and severe), asymmetries, and deformities were treated with m-PM, implants, and FG, and their outcomes were compared with those in a control group (CG) (n = 35) treated with t-PM and implants. Aesthetic outcomes were evaluated using the patient's satisfaction grade, physician's assessment score, and visual Analog Scale (VAS).

RESULTS

Overall, 75% (n = 30) of SG patients reported excellent results in terms of breast lift, shape, volume, NAC position, and scar quality after 12 months, whereas the CG reported the same outcomes in 60% (n = 21) of the cases. SG patients showed a vertical NAC shift and a satisfaction degree higher than that in the CG (p < 0.001 vs. CG).

CONCLUSIONS

The m-PM with implants and FG was found to be safe and effective in this trial.

Autologous Micrografts Containing Nanovesicles, Exosomes, and Follicle Stem Cells in Androgenetic Alopecia: In Vitro and In Vivo Analysis Through a Multicentric, Observational, Evaluator-Blinded Study

BACKGROUND

The use of micrografts (MCGs) containing human follicle mesenchymal stem cells (HF-MSCs) is a hair loss (HL) treatment that needs to be standardized as seems to have promising effects on hair regrowth (HR-G) also thanks to the presence of extracellular vesicles (EVs).

OBJECTIVES

The study aims to report both the in vivo results, obtained in patients affected by androgenic alopecia (AGA) treated using MCGs, and in vitro analysis characterizing the EVs.

METHODS

A multicentric, retrospective, observational, evaluator-blinded study was conducted. Eighty-three AGA patients were initially enrolled [52 suffering from male pattern hair loss (MPHL) at stages I-III vertex by the Norwood-Hamilton scale and 31 suffering from female PHL (FPHL) at stages I-II by the Ludwig scale]. Sixty patients (20 females and 40 males) were treated and analyzed after exclusion and inclusion criteria assessment. The in vivo HR-G was evaluated through photography, physician's, and patient's global assessment scales, in addition to standardized photo-trichograms, during a follow-up for 1 year, while the in vitro analysis was performed through a quantitative, morphological, and dimensional characterization of the EVs population using transmission electron microscopy (TEM) and fluorescent microscopy.

RESULTS

A hair density (HD) increase of 28 ± 4 hairs/cm2 at T4 after 12 months in the targeted area (TA) of FPHL, compared with the baseline, was observed using computerized trichograms with a statistically significant difference (SSD) in hair regrowth (HR-G) (p = 0.0429). Regarding MPHL, an HD increase of 30 ± 5 hairs/cm2 at T4 after 12 months in the TA was observed with an SSD in HR-G (p = 0.0012). The presence of EVs and their interaction with the surrounding cellular population were demonstrated.

CONCLUSIONS

MCGs containing HF-MSCs and exosomes may fill in as a safe and viable alternative treatment against HL in mild and moderate degrees of AGA both in MPHL and in FPHL.

Comparison of commercial fibrin sealants in facelift surgery: a prospective study

BACKGROUND

The aim of this study was to compare the effects of two types of fibrin glue in patients undergoing facelift surgery.

METHODS

A prospective, controlled "right-left side" study was carried out in 20 patients. The two fibrin sealants used were Quixil® and Tissucol®. The two sealants were used at the same time, ie, one on one side of the face and the other on the contralateral side. Comparisons were made with regard to rates of hematoma and seroma, degree of induration, edema, ecchymosis, pain levels, and patient satisfaction.

RESULTS

The results were almost equivalent. The only exception was a significant (40 mL) hematoma in a patient treated with Quixil. Bleeding was most likely due to a sudden rise in blood pressure during the immediate postoperative period. However, it must be emphasized that, while Tissucol actually seals the undermined area, thus virtually eliminating the dead space, Quixil acts differently, in that its effectiveness in preventing hematoma is linked mainly to its hemostatic effect.

CONCLUSION

The two fibrin sealants used were nearly identical with regard to patient safety and quality of the result. Nevertheless, it is noted that, while Tissucol has both hemostatic and "gluing" effects, Quixil is mainly effective in securing hemostasis.

Photobiostimulation Therapy (PBST) and Pulsed Electromagnetic Field Therapy (PEMF) in Hair Loss Treatment: Multicentric, Retrospective, Case-Control Study

BACKGROUND

The combined use of micro-needling (MND), growth factors (GFs), and low-level light/laser therapy (LLLT), here identified as photobiostimulation therapy (PBST) and pulsed electromagnetic field therapy (PEMF), is a hair loss (HL) treatment that needs to be standardized as it seems to have promising effects on hair regrowth (HR-G).

OBJECTIVES

The study compared the clinical and instrumental results obtained in patients affected by androgenic alopecia (AGA) and HL related to COVID-19 treated using PEMF combined with PBST with those obtained by only PBST.

METHODS

A multicentric, retrospective, observational, case-control study was conducted. Fifty-three patients were initially enrolled (30 males classified as stages I-III vertex by the Norwood-Hamilton scale, while 23 females classified in stages I-II by the Ludwig scale). Forty patients (20 females and 20 males) were analyzed after exclusion and inclusion criteria assessment. Twenty patients were treated with the combined use of PEMF and PBST (study group - SG) while 20 patients were treated with PBST (control group -CG). The HR-G was evaluated through photography, physician's, and patient's global assessment scales, in addition to standardized phototrichograms, during a short follow-up at T0-baseline, T1-16 weeks.

RESULTS

The promising results in SG patients, represented by a hair count (HC) increase of 14 hairs/0.65 cm2 at T1 after 16 weeks in the targeted area, compared with the baseline results (41 ± 2 hairs/0.65 cm2 at T1 versus 27 ± 2 hairs/0.65 cm2 at baseline), were observed using computerized trichograms. There was a statistically significant difference in HR-G (p = 0.0325) compared with an HC increase of 11 ± 2 hairs/0.65 cm2 in the CG.

CONCLUSIONS

The comparison between SG and CG indicated that PEMF combined with PBST was a more efficient strategy in HR-G in terms of HC improvement than PBST alone.
