L Benzekri, Y Gauthier
The current methods for melanocyte delivery to depigmented skin are invasive and often require sophisticated approaches. Here we describe a promising simple and minimally invasive technique based on the dermarolling system. The technique involves preparation of a keratinocyte/melanocyte suspension prepared by trypsinization from a non-lesioned part of a patient's scalp skin and transepidermal delivery using a dermaroller equipped with 0.2 mm needles. Dermarolling leads to epidermal microinjuries without, however, causing pain or inflammation...

BACKGROUND: Optimal control of minimally invasive interventions by hyperthermia requires dynamic temperature mapping at high temporal resolution. METHODS: Based on the temperature-dependent shift of the proton resonance frequency (PRF), this work developed a method for real-time MRI thermometry which relies on highly undersampled radial FLASH MRI sequences with iterative image reconstruction by regularized nonlinear inversion (NLINV). As a first step, the method was validated with use of a temperature phantom and ex vivo organs (swine kidney) subjected to heating by warm water or a pulsed laser source...

Functionalized multi-walled carbon nanotube (fMWCNT) development has intensified to improve their surface activity for numerous applications, and potentially reduce toxic effects. Although MWCNT exposures are associated with lung tumorigenesis in vivo, adverse responses associated with exposure to different fMWCNTs in human lung epithelium are presently unknown. This study hypothesized that different plasma coating functional groups determine MWCNT neoplastic transformation potential. Using our established model, human primary small airway epithelial cells (pSAECs) were continuously exposed for 8 and 12 weeks at 0...

Laparoscopic pancreaticoduodenectomy (LPD) is a minimally invasive approach for Whipple by total or assistant laparoscopic techniques. The results of feasibility, safety, short and long outcomes have slowly been gaining acceptance over the past decade. Aim to further adapt to the development trend, improve the safety and oncologic outcomes, promote the standardized development of LPD in China, four pancreas surgery groups in China wrote this LPD consensus. The consensus includes seven sections: operator request, indications and contraindications, preoperative preparation and anesthesia, equipment and instruments, positioning of patient and trocars, abdominal pressure, indications of conversion to laparotomy, postoperative observation and treatment...

INTRODUCTION: After laparoscopic cholecystectomy, laparoscopic fundoplication has become another gold standard of minimal invasive surgery. The level of satisfaction of patients undergoing endoscopic surgery is almost 90%. Laparoscopic fundoplication, like other surgery methods, can also be burdened with grave complications, which could result in a fatal outcome even if the surgery is performed by a skilled surgeon. Even the authors themselves encounter complications despite their rich experience (more than 3,500 laparoscopic operations in the diaphragmatic hiatus area in more than 20 years)...

The aim of this study was the development of novel fluorescent microspheres as embolic agent for transarterial embolization (TAE) of advanced stages of hepatocellular carcinoma (HCC). TAE is a minimally invasive procedure that induces tumour regression blocking the blood flow by injection of microparticles. The microspheres currently used in clinical application cannot be visualized in vivo. Surgeon could exploit the intraoperative detection of embolic agents during resection of the malignant mass. Biocompatible indocyanine green (ICG)-loaded microspheres (CAB-CS-ICG) were prepared using a multi-step method...

Nanoparticles (NPs) are potential drug delivery vehicles for treatment of a broad range of diseases. Intravenous (IV) administration, the most common form of delivery, is relatively non-invasive and provides (in theory) access throughout the circulatory system. However, in practice, many IV injected NPs are quickly eliminated by specialized phagocytes in the liver and spleen. Consequently, new materials have been developed with the capacity to significantly extend the circulating half-life of IV administered NPs...

BACKGROUND: The use of dermal fillers in minimally invasive facial aesthetic procedures has become increasingly popular of late, yet as the indications and the number of procedures performed increase, the number of complications is also likely to increase. Paying special attention to specific patient characteristics and to the technique used can do much to avoid these complications. Indeed, a well-trained physician can also minimize the impact of such problems when they do occur. METHODS: A multidisciplinary group of experts in aesthetic treatments reviewed the main factors associated with the complications that arise when using dermal fillers...

The aim of this study was to evaluate the accuracy of bone sounding (BS) in assessing the facial osseous-gingival tissue relationship (FOGTR) of failing maxillary anterior teeth. Dental records of patients who received immediate implant placement (IIP) at the maxillary anterior area were screened. Mid-FOGTR prior to extraction (BS), and immediately after flapless extraction (direct bone level [DBL] measurement) were analyzed. A total of 160 patients with 190 maxillary anterior teeth were included. The mean FOGTR obtained from BS and DBL were 3...

BACKGROUND: People with heart failure and preserved ejection fraction develop increases in left ventricular (LV) end-diastolic pressures during exercise that contribute to dyspnea. In normal open-chest animal preparations, the pericardium restrains LV filling when central blood volume increases. We hypothesized that resection of the pericardium using a minimally invasive epicardial approach would mitigate the increase in LV end-diastolic pressure that develops during volume loading in normal and diseased hearts with the chest intact...

BACKGROUND: Noninvasive external volume expansion device has been applied to stimulate nonsurgical breast enlargement in clinical settings. Although previous results demonstrate the capacity of external volume expansion to increase the number of adipocytes, this strategy alone is insufficient to reconstruct soft-tissue defects or increase breast mass. The authors combined a minimally invasive tissue dissection method with external volume expansion to generate large volumes of adipose tissue...

Ultrathin veneer is a new therapeutic technology developed from minimally invasive theories. Ultrathin veneer alters the unwanted shape and color of a tooth through minimal or lack of preparation. The color of tooth after restoration is mixed with the natural color of tooth, the original color of veneer, and the color of bonding material because of ultrathin (approximately 0.2 mm) veneer. Thus, the color is affected by numerous variations. Full considerations are required for creating designs. The author summarizes clinical points and provides suggestions for ultrathin veneer in color...
