Methods: It consists of a small portable device to stimulate sweating, running a 9-volt battery. The drops of sweat produced are monitored and can be photographed sequentially or continuously recorded on digital video by camera positioned at some distance from the skin. The images are then analyzed by software able of counting the drops at specific time, being able to monitor their development to its confluence. Conclusion: The small size and weight make it easily transportable. It is thus possible to record continuous and dynamic analysis of sweating, using a national method, simple, cheap and not very laborious.

This is a rare injury that may be challenging to diagnose, and necessitates early identification and treatment to achieve the best outcomes. We report the case of a 45-year-old male patient who was referred to our institution for large wound closure after undergoing debridement of a misdiagnosed MLL that became complicated by infection and sepsis. The patient was retrospectively diagnosed with a Stage VI MLL and had to undergo 4 operations with skin grafting and vacuum-assisted closure therapy playing an essential role in achieving tissue closure. This case was presented as a reminder of this rare diagnosis, and the importance of considering it when faced with a patient presenting with a relevant clinical picture post trauma. An early diagnosis is important because early intervention can preve...

Optimal staining and fixation techniques of the surgical piece are essential. In a previous study investigating myofibroblasts and contraction in split skingraft donor sites, a low density of myofibroblasts was observed, as opposed to studies in granulation studies. To investigate the causes for this finding and based on a specific manuscript on the efficacy of immunohistochemi cal visualization using different tissue fixation methods, we compared the efficacy of fixation in 10% formaldehyde and 70% alcohol for the visualiza tion of myofibroblasts in granulation tissues of chronic ulcers in 21 patients. Method: Forty-two samples were studied by immunohistochemistry, using the anti-Smooth Muscle Actin antibody, and myofibroblasts were counted in 10 fields with a magnification of 400X. Results: Better qualitative and quantitative results were o...

This entails the use of surgical instruments that need to be autoclaved and to have a power source, which usually requires an OR facility. The minced skin technique uses single use, presterilized instruments and the procedure can be done under local anesthesia, by a wound care practitioner, in a wound clinic, a physician's office or even at the bedside. The current study was designed to determine if the results from micrografting were non inferior to conventional mesh grafting.MethodsIn a prospective non inferiority study, 26 chronic ulcers were treated with micrografting (MSG) and 24 with conventional mesh grafts 1:3 (control group‐CG) in a total of 21 patients, 10 male and 11 female. The donor site areas in the MSG group were predetermined to 2.5 × 5 cm and the mesh grafts expansion was set at 1:3.ResultsIn th...
