Non-invasive cryolipolysis for fat reduction in flanks in Chinese with a modified applicator

OBJECTIVE: To determine the patient satisfaction and clinical efficacy of a modified applicator with a cryolipolysis device (ZeltiqR) for fat reduction in the flanks in Chinese. METHODS: A total of 15 healthy adult subjects with clearly visible fat in the flanks that wish to have them reduced were recruited. All received a single free treatment. Parameters were pre-set at cooling intensity factor of 41.6 (-73 mW/cm2) for 60 minutes per site. The efficacy is determined by comparing measurements and comparing photographs taken at baseline, and 8 weeks and 12 weeks …published_or_final_versio

Efficiacy of a high-intensity focused ultrasound device for non-invasive body contouring

OBJECTIVE: High-intensity focused ultrasound (HIFU) is a non-invasive technology for body contouring. HIFU is focused within the subcutaneous adipose tissue, causing coagulative necrosis and cell death. The objective of this study was to evaluate the effectiveness of a HIFU device for sculpting of the abdomen. METHODS: The system has a set focal depth of 1.3 cm. Twelve subjects with adipose thickness of no less than 2.5 cm who met the screening criteria were recruited. Each subject received one treatment to the abdomen. The total fluence used per site was 150-165 J/cm2 with a mean of 161 J/cm2. The waist circumference at iliac crest and the point of maximum circumference were recorded at baseline …published_or_final_versio

Electroacupuncture provides a new approach to neuroprotection in rats with induced glaucoma

Objectives: To investigate, using multifocal electroretinogram (mfERG), the effect of electroacupuncture (EA) on retinal function in rats with experimental glaucoma. Design and subjects: Glaucoma was induced in the right eyes of 15 adult female Sprague-Dawley rats by laser photocoagulation for three quarters of the perilimbal and episcleral vessels. The left eye of each rat was used as the control. The animals were divided into 3 groups: no treatment (non-EA control group), 2 Hz EA group, and 100 Hz EA group. EA treatment at different frequencies can produce different levels of analgesia and hence the effect of EA with different frequencies on glaucoma treatment was investigated. Both eyes of each rat in the EA experimental groups received 3 EA treatment sessions each week for 4 weeks. The retinal function was measured using mfERG after 4 weeks of EA treatment. Results: There was no significant difference in the amplitude (both N1 trough and P1 peak) of mfERG first- order kernel response between the treatment and control groups. In determining the waveform characteristics by the ratio of N1 amplitude to P1 amplitude (N/P ratio), obvious differences were found in the N/P ratio between the control eyes and the glaucoma eyes in the non-EA group and the 100 Hz EA treatment group, but similar values in the N/P ratio were observed between the control eyes and the glaucoma eyes in the 2 Hz EA treatment group. The waveform from the eyes with glaucoma was deformed in both the non-EA group and the 100 Hz EA group, but the waveform from the glaucomatous eye was preserved in the 2 Hz EA group. Conclusions: Application of EA at 2 Hz provides neuroprotection by preserving retinal function in rats with experimental glaucoma. Low frequency EA may be an alternative therapy in the treatment of glaucoma. © Mary Ann Liebert, Inc.published_or_final_versio

The efficacy of a microwave device for treating hyperhidrosis in Chinese

OBJECTIVE: Hyperhidrosis affects the quality of lives. A non-invasive, microwave device selectively heats the targeted region where the sweat gland resides. The objective of the study was to assess the efficacy and patient satisfaction after treatment. METHODS: Ten Chinese subjects with skin type III-IV with axillary hyperhidrosis were enrolled. Subjects were required to have a Hyperhidrosis Disease Severity Scale (HDSS) score …published_or_final_versio

Safety and efficacy evaluation of a combined device using infrared light and bipolar radiofrequency and sublative radiofrequency applicators

OBJECTIVE: The combined infrared light and bipolar frequency and sublative radiofrequency dual handpiece device is intended for dermatological procedures requiring ablation and resurfacing of the skin. The objective of this study was to evaluate the safety and efficacy of the combined sublative radiofrequency and sublime applicators for the treatment of wrinkles. METHODS: Twenty subjects were recruited of whom 16 received the treatment and were followed up till 3 months. Each patient was treated once, first with the sublime applicator which used a combination of …published_or_final_versio
