Cellulite Pathophysiology and Psychosocial Implications

BACKGROUND

Cellulite is a highly prevalent aesthetic condition in postpubertal women.

OBJECTIVE

The objective of this article was to describe the latest data on the pathophysiology of cellulite and to highlight the psychosocial aspects that should be considered when treating cellulite.

METHODS

A roundtable meeting was convened to discuss and share views on the latest data on the pathophysiology and psychosocial aspects of cellulite. The participants' experience helped guide a narrative review on this topic.

RESULTS

The pathophysiology of cellulite primarily involves fibrous septal changes. Strategies targeting the fibrous septa have shown the most consistent efficacy, while showing inconsistent or short-term results when targeting the other components of cellulite, such as decreased dermal thickness, vascular alterations, and inflammation. Female sex, increased age, and high body mass index contribute to cellulite pathophysiology.

CONCLUSION

Patients seeking treatment for cellulite are willing to endure numerous treatments, high cost, temporary and/or delayed results, and invasive procedures with potential adverse effects. Psychological discomfort has been reported among patients with cellulite, and understanding their behaviors and psychological characteristics can help clinicians provide better care to these patients seeking treatment.

Shock Wave Therapy in Plastic Surgery: A Review of the Current Indications

BACKGROUND

Extracorporeal shock wave therapy (ESWT) represents a promising, non-invasive management strategy supporting the treatment of a variety of conditions related to plastic surgery.

OBJECTIVES

This literature review aimed to give a systematic overview of current applications, its mechanism of action, and its potential to provide tangible therapies in plastic surgery.

METHODS

The databases PubMed (National Institute of Health, Bethesda, MD), Embase (via Ovid [Elsevier, Amsterdam, the Netherlands]), and the Cochrane Library (Cochrane, London, UK) were searched for articles published up to June 1, 2021. Clinical studies of any design including ESWT in the context of plastic surgery were included. Two reviewers extracted data, and 46 articles were analyzed after application of the inclusion and exclusion criteria.

RESULTS

Forty-six included studies (n = 1496) were categorized into the following broad themes: cellulite/body contouring/skin rejuvenation, burns/scar treatment, diabetic foot ulcers/chronic wound, and future perspectives of ESWT. Overall, applications of ESWT were heterogenous, and the majority of studies reported effectiveness of ESWT as an alternative treatment technique. Flawed methodology and differences in technical standards limit the outcome and conclusion of this review.

CONCLUSIONS

There is yet insufficient evidence to support the effectiveness of any specific intervention included in this review; however, all included studies reported improvements in key outcomes. Where reported, ESWT displayed a good safety profile with no serious adverse events. Further research is needed to provide more evidence to delineate the indications of ESWT in plastic surgery.

Effect of Extracorporeal Shock Waves on Induced Neocollagenesis of Integumentary Tissue

BACKGROUND

Obesity became a worldwide public health problem and its treatment presents a strict relationship with skin flaccidity, for which the development of non-invasive therapies is an emerging field.

OBJECTIVE

This study aims to evaluate the physiological response of the skin tissue of individuals with obesity with flaccidity to the physiological stimulus of shockwave therapy (ESWT).

METHODS

This is a comparative intervention study based on histological and immunohistochemical analyses of a set of samples of skin tissue of women with Grade II obesity who achieved a 10 percent preoperative weight loss before bariatric surgery and complaints of skin flaccidity, subjected to the ESWT treatment. A total of seven sessions were carried out in the abdominal region on the left side, and the collateral side was used as control; the biological material was collected at the moment of the bariatric surgery. Hematoxylin and Eosin, Masson's trichrome, Picrosirius Red and the markers for immunohistochemical were used for the morphological evaluation.

RESULTS

Fourteen women were included in the research. The results demonstrated that the tissue which underwent the ESWT intervention presented significant increases of fibroblast cells (p<0.0001) and collagen fibers Type I and II (p<0.0002). In the significant expressions of the markers FGF1, FGF2, FGFR1 were identified in the exposed side (p<0.0002, 0.0017, <0.0001, respectively) as well as a significantly higher expression of Ki67 marker of cell proliferation (p<0.0002).

CONCLUSION

ESWT was associated with a significant increase of cell proliferation and collagen expression in flaccid skin of individuals who achieved weight loss before bariatric surgery.

Effects of LED photobiomodulation therapy on the subcutaneous fatty tissue of obese individuals - histological and immunohistochemical analysis

Photobiomodulation therapy (PBMT) has become an adjuvant therapeutic possibility in body remodeling procedures. Given this scenario, this study was proposed with the aim of evaluating the effects of PBMT to Light Emitting Diode (LED) associating the red (630 nm) and infrared (850 nm) wavelengths in the subcutaneous fatty tissue. This controlled study of comparative intervention that evaluated a sample of subcutaneous fatty tissue from women with grade II obesity. The participants received the LED PBMT treatment with associated red and infrared wavelengths sequentially on the left side of the abdomen and the right side was considered as control, with the collection of biological material performed at the time of bariatric surgery. For histological and immunohistochemical evaluation, Caspase 3, Cleaved Caspase 3, CD68+, HSL and adipophilin markers were used. The participants showed positivity in the expression of Caspase 3 and Cleaved Caspase (p < .0001), CD68+ macrophages (p < .0001), HSL (p < .0001) and adipophilin (p < .0013) in the intervention sample when compared to the control. PBMT and LED associating red and infrared wavelengths were able to promote autophagic lipolysis induced by adipocyte cell apoptosis in the subcutaneous tissue of obese individuals.

Microwave Therapy for Cellulite: An Effective Non-Invasive Treatment

Background: Cellulite represents a common cosmetic problem that affects nearly all women. This study aimed to evaluate microwave therapy’s effectiveness for cellulite treatment. Methods: In this study, 26 women showing severe or moderate cellulite underwent four sessions of microwave therapy on the buttocks and posterior thighs. The following assessments were performed at baseline and the three-month follow-up after the last treatment: the Cellulite Severity Scale (CSS), Nürnberger–Müller classification scale, photographic evaluation, and buttocks/posterior thighs circumference measurements. A Likert scale questionnaire was used to assess patient satisfaction at the 3-month follow-up. Results: The treatment positively affected the cellulite severity as confirmed by the Cellulite Severity Scale (CSS) and Nürnberger–Müller classification scale results. CSS showed a significant amelioration in cellulite severity between the initial assessment and the 3-month follow-up for the buttocks and posterior thighs, with total average scores that ranged from 10.7 ± 3.1 to 4.5 ± 1.8 (p < 0.01). The treatment also resulted in a remarkable improvement in comfort/satisfaction and a buttocks and posterior thighs circumference reduction. No serious adverse events were observed. Conclusions: Microwave therapy has proven to be a safe treatment for improving cellulite appearance and reducing body circumferences.

Effect of extracorporeal shock waves on inflammation and angiogenesis of integumentary tissue in obese individuals: stimulating repair and regeneration

The technology of extracorporeal shock wave therapy (ESWT) has been studied around the world for its possible benefits in the treatment and rehabilitation of aesthetic disorders. To better elucidate its real physiological effect on the integumentary tissue, this study was proposed aimed at evaluating whether ESWT can act to stimulate the inflammatory process and angiogenesis in the dermis and epidermis of obese individuals. This is an immunohistological study that evaluated a set of samples of the integumentary tissue of women with grade II obesity with weight loss of 10% of the initial weight undergoing ESWT treatment; the collection of biological material was performed at the time of surgery of bariatric surgery. For immunohistochemical evaluation, the markers to assess the presence and distribution of inflammatory cells, anti-COX-2, CD3, CD20, CD163, and NK were used. For physiological stimulus pathways for blood vessel angiogenesis, markers CD 34, CD 105 and VEGF were used. Fourteen obese women were included in the study. Positivity was evidenced in the epidermal expression of markers of the inflammatory process COX-2, CD3, CD20, NK cells, CD68, and CD163 (p < 0.0001) in the intervention sample when compared to controls. There was a positive expression for the angiogenesis markers CD105 and VEGF (p < 0.0001) when comparing the intervention group with the control group. It was concluded that ESWT can stimulate a local inflammatory process, mediating and modulating important growth factors to act in the repair process and skin tissue regeneration, being considered a promising treatment for skin diseases related to weight gain or loss.

The BODY-Q Cellulite Scale: A Development and Validation Study

BACKGROUND

Cellulite is a localized metabolic disorder of the subcutaneous tissue. To measure the impact of cellulite and its treatment(s) on patients' health-related quality of life, a psychometrically sound patient-reported outcome measure is needed.

OBJECTIVES

The authors sought to develop and field test a new BODY-Q cellulite scale to measure the appearance of cellulite.

METHODS

Appearance-related codes from the original BODY-Q qualitative interviews were reexamined, and a set of cellulite-specific items was developed and refined through cognitive patient interviews (n = 10) and expert input (n = 17). This scale was field-tested in adults with cellulite through 2 crowdworking platforms. Rasch Measurement Theory analysis was employed to refine the scale and examine its psychometric properties.

RESULTS

The field-test sample included 2129 participants. The 15-item scale was reduced in length to 11 items. Data from the sample fit the Rasch model (X2 [99] = 21.32, P = 0.06). All items had ordered thresholds and mapped out a targeted clinical hierarchy. The reliability statistics for the person separation index was 0.94 and for Cronbach's alpha was 0.97. In terms of validity, worse scores on the cellulite scale were associated with being more bothered by how the cellulite looked overall, having more severe cellulite on the Patient-Reported Photo-numeric Cellulite Severity Scale, and having more self-reported cellulite and more areas of the body with cellulite.

CONCLUSIONS

The BODY-Q cellulite scale can be utilized to measure appearance of cellulite and provides a solid basis for future studies evaluating the impact of cellulite and its treatment.
