Background/Aims: Recently classified as an epidemic by the WHO, obesity (as well as the state of being overweight) clearly affects significant populations across all ages. The relationship between obesity and some diseases (e.g. cardiovascular ones) is known, although many paradoxes remain to be explained. Very little information is available, however, regarding its impact on skin physiology and skin disease. This study aims to examine the influence of excessive weight on epidermal hydration and transepidermal water loss, key variables of skin water balance and skin biomechanics. Methods: A convenience sample of 89 healthy female volunteers was selected and divided into 4 groups, according to their BMI (body mass index), as normal (control), overweight, obese (I and II), and morbid. Skin physiology was quantitatively assessed in all individuals in 4 anatomical areas using non-invasive biometrical analysis by reference instrumentation. Descriptive and comparative statistics were applied, adopting a confidence level of 95%. Results: A non-linear alteration for all variables was detected as a function of BMI. Conclusion: Results suggest that excessive weight might favour skin performance within certain limits, reflecting a particular adaptation of the skin to the weight gain and body contour. © 2017 S.

Objective: To analyze a case series of patients who underwent injection of industrial liquid silicone in a clandestine manner and by unauthorized persons. Methods: We conducted a retrospective analysis of medical records of patients treated between September 2003 and December 2010. Data regarding gender, age, location and volume of silicone injected, time between application and clinical manifestations, complications, treatment and outcome were collected. Early manifestations were defined as occurring within 30 days of injection and late manifestations, the ones arising after this period. Results: We treated 12 patients, eight were male, seven transsexuals. The volume injected ranged from 5ml to 2000ml, being unknown in three cases. The most often used injected sites were the thighs and buttocks. Eight patients had early manifestations, with inflammation and/ or infection. Surgical debridement was necessary in five cases. Three patients with a history of injection in the breast region underwent adenomastectomy. There was one death due to refractory septic shock. Conclusion: The use of industrial liquid silicone should be completely contraindicated as a filling material and modification of body contouring, and may have serious complications, even death.

To determine if the use of botulinum toxin during cheiloplasty could help in the management of tension at the surgical wound level.Five children younger than six months of age, who were born with complete cleft lip and palate, were treated with a dose of 10 units of botulinum toxin injected into the upper lip during surgery. Before the surgery, an electromyographic study was carried out on the patients upper lips. A Millard-type cheiloplasty was performed and 10 days later, a second electromyographic study was performed on the upper lips of all the patients.There was a significant change (P<0.039) in the electromyographic tracing obtained after the application of botulinum toxin, especially during rest.As confirmed by electromyography, botulinum toxin effectively inhibits the action of the orbicularis oris muscle, especially when at rest; consequently, the tension is decreased at the level of the surgical wound.

Liposuction is a highly sought after surgical procedure. Despite its popularity, not all of the factors associated with its execution are well understood. No well-established guidelines exist for plastic surgeons regarding the subcutaneous infiltration of fluid and, thus, the procedure is often performed subjectively.To establish the usefulness of the Quito formula (infiltrate volume = weight [kg] percentage of body surface to be liposuctioned 2.4 [mL]) for calculating the volume of fluid to be infiltrated subcutaneously during small-volume liposuction performed under epidural anesthesia.A prospective study was conducted on a group of 50 patients who were candidates for liposuction on multiple body parts between November 2004 and February 2010.The maximum volume of infiltrate was 5000 mL and the maximum volume of aspirate was 4500 mL, with a 30% total aspirated area. No patient required blood transfusion, and there were no major complications. However, one patient presented with a small local infection, another with a sacral seroma and two patients had postdural puncture headaches. No patient showed clinical signs consistent with overhydration, dehydration, pulmonary embolism, fat embolism or lidocaine intoxication.When performing small-volume liposuction, subcutaneous infiltration using the Quito formula to calculate the volume of infiltrate proved to be useful, safe and objective.
