Comparative thermographic analysis at pre- and postcryolipolysis treatment: Clinical case report

Cryolipolysis Does not Modify the Behavior and Recovery of Cardiac Autonomic Modulation

The desire to reduce and remodel undesirable fatty deposits has increased the popularity and use of aesthetic procedures, among them, cryolipolysis. However, repercussions on the autonomic nervous system must be considered, since the decrease in cutaneous body temperature can have repercussions on sympathetic and parasympathetic components. The aim was to evaluate the behavior of cardiac autonomic modulation during and after a single application of cryolipolysis. A single-arm, prospective interventional study evaluated data from 13 women with a mean age of 22.38 ± 2.95 years, who had an accumulation of abdominal fat of at least 1.5 mm, were using oral contraceptives, and were sedentary. A professional applied cryolipolysis in a single 40-min session. RR intervals were collected by means of a cardiofrequency meter, at rest prior to the technique for 10 min, during the performance of the technique, and immediately after the end of the technique for a period of 50 min. Heart rate variability (HRV) analysis was performed using time, frequency, and Poincaré plot indices. For the mean RR, SDNN, rMSSD, SD1, SD2, and LF [ms²] indices, the values increased during the execution of cryolipolysis when compared to rest. In the recovery period, increases in the mean values of the RR, SDNN, rMSSD, SD1, SD2, HF [ms²], LF [nu], and HF [nu] indices were also observed when compared to the baseline moment. Both during the technique and in the recovery period, there were changes in the behavior of HRV characterized by an increase in global and vagal indices.

Evaluation of skin using infrared thermal imaging for dermatology and aesthetic applications

INTRODUCTION

The use of thermography in the medical field has been experiencing a renaissance due to advances in the infrared thermographic imaging technology, which improves thermographic equipment and promises cost saving and increased safety. Dermatology is one of the most promising fields of application among the medical areas with potential for the use of thermography.

OBJECTIVE

To review the findings on this subject and to describe the use of such technique for dermatology and aesthetic applications.

METHODS

A bibliographic survey was carried out, selecting relevant publications and guidelines, focused on monitoring medical diagnostic applications and benefits of thermography for dermatology, inflammatory skin diseases, and aesthetic applications.

RESULTS

Inflammatory skin diseases lead to changes of the IRT image. A quantification of treatment effects and monitoring changes on skin can be possible by repeated measurements over time.

CONCLUSION

Infrared imaging is a noninvasive, powerful tool in the diagnosis and clinical management of skin conditions and monitoring of aesthetic procedures.

Cryolipolysis (CLL) for Reduction of Localized Subcutaneous Fat: Review of the Literature and an Evidence-Based Analysis

INTRODUCTION

In recent years, cryolipolysis (CLL), a noninvasive approach based upon the inherent sensitivity of adipocytes to cold injury, has emerged. However, it is not clear whether available evidence to date about its efficacy justifies aggressive marketing and extensive widespread application by many practitioners without well-defined indications or objectives of treatment. The current review is intended to evaluate available evidence regarding CLL mechanisms of action and its efficacy not only in fat reducing but also in its ability to result in an aesthetically optimal outcome.

MATERIALS AND METHODS

A systematic search of PubMed and Scopus computerized medical bibliographic database was conducted with the search terms "cryolipolysis," "lipocryolysis," and "cool sculpting." Selection criteria included all matched reports with the search terms in their titles.

RESULTS

Thirty-two reports matched the inclusion criteria of this review. Five experimental studies were identified and included to further supplement the discussion.

CONCLUSION

Most reports about CLL included in this review lacked rigorous scientific methodology in study design or in outcome measurement. Serious concerns about integrity of many of these reports, particularly with respect to validity of photographic outcome documentation in addition to objectivity, conflict of interest issues, and commercial bias, have been expressed. Further research should be encouraged to prove with methodological rigor positive effects of this treatment modality and to determine categories of patients in whom most favorable outcomes might be expected.

Systemic Effects of Cryolipolysis in Central Obese Women: A Randomized Controlled Trial

BACKGROUND AND OBJECTIVES

To investigate the adding effect of Cryolipolysis to a low-calorie diet program on lipid profile, liver enzymes, body mass index, waist-to-hip ratio, and volume reduction of subcutaneous fat tissue in central obese women.

STUDY DESIGN/MATERIALS AND METHODS

Sixty central obese women were randomly divided into two equal groups. Women in the control group received prescribed low-calorie diet regimen only, while women in the study group received three Cryolipolysis sessions plus the same dietary regimen for 3 months. Assessment of women in each group for weight, height to obtain the body mass index, waist-to-hip ratio, and abdominal subcutaneous fat thickness as well as evaluation of lipid profile and liver enzymes was done just before starting the treatment procedures and immediately after ending the study duration.

RESULTS

There were statistically significant improvements of waist-to-hip ratio, body mass index, total cholesterol, triglycerides, low- and high-density lipoprotein, as well as liver enzymes in favor of the study group (P < 0.001).

CONCLUSION

Women who underwent Cryolipolysis and diet program had better improvement in components of lipid profile and liver enzymes than women who were maintained over diet program alone. Measures to decrease waist circumference, associated with abdominal subcutaneous fat reduction, enhanced the systemic effects of Cryolipolysis. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.
