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

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

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

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

The Efficacy of Energy-Restricted Diets in Achieving Preoperative Weight Loss for bariatric Pateints: A Systematic Review

The final publication is available at Springer via https://doi.org/10.1007/s11695-018-3451-1In bariatric practice, a preoperative weight loss of at least 5% is recommended. However, the hypocaloric diets prescribed vary and no consensus exists. This study examined the efficacy of preoperative diets in achieving 5% weight loss. From a systematic literature search, eight randomised controlled trials (n = 862) were identified. Half of the trials used a Bvery-low-calorie diet^ whilst the rest employed a Blow-calorie diet^. Only five diets achieved ≥ 5% weight loss over varying durations and energy intakes. By inference, compliance with a 700–1050 kcal (2929–4393 kJ) diet, consisting of moderate carbohydrate, high protein and low/moderate fat, for 3 weeks is likely to achieve 5% weight loss. A low-carbohydrate diet (< 20 g/day) may achieve this target within a shorter duration. Additional research is required to validate these conclusions
