However, no study has investigated the long-term safety and effectiveness of FACILLE. Thus, a retrospective study of 14 aesthetic clinics in China was conducted. This was the first large-scale, postmarketing study on FACILLE to evaluate the occurrence of adverse events (AEs) and provide essential information on the satisfaction of patients with FACILLE injections. This study recruited participants aged >18 years. FACILLE was injected into the NLFs on both sides of each participant’s face. The primary endpoint for safety was systemic or severe AEs at an injection site. Effectiveness was assessed on the basis of the participants’ subjective perceptions and satisfaction levels. Safety and effectiveness data were collected on the day of injection and at 2 weeks and 1, 3, 6, 9, 12, 18, 24, 30 and 36 months postinjection. In total, 1552 participants were enrolled (mean age, 29.1 years), and most of them (96.5%) were women. The mean injection volume was 1.39 ± 0.658 mL, and the average number of injections was 2.4 ± 1.68. AEs were reported by 205 participants (13.2%). All AEs occurred at local injection sites. No systemic or severe AEs were observed. Local pain was the most frequently reported AE regardless of the number of injections or the injection volume. Only eight AE cases were correlated with FACILLE administration, with two cases involving local allergic reactions. The participants self-reported that they perceived the procedure to have an effectiveness of ≥90% within 6 months postinjection although this percentage decreased substantially after 9 months. Their satisfaction level was >90% within 1 month postinjection but decreased gradually after 3 months. Our results indicate that the long-term safety of FACILLE injection is adequate. The high self-reported perceived effectiveness and satisfaction levels indicate the considerable potential of FACILLE injections for correcting NLFs.展开更多

The first case was a 66-year-old woman who underwent endoscopic retrograde cholangiopancreatography and endoscopic retrograde papillotomy, and then A. baumannii bacteremia occurred. The second case was a 70-year-old female who underwent endoscopic retrograde biliary drainage due to obstruction of intra-hepatic ducts, and bacteremia occurred due to polymicrobes (Escherichia coli , viridans streptococcus , and A. baumannii ). After a literature review, we suggest that correct gastroendoscopy technique and skill in drainage procedures, as well as antibiotic prophylaxis, are of paramount importance in minimizing the risk of gastroendoscopy-associated bacteremia.展开更多

The treatment of acne is sometimes frustrating due to the emergence of antibiotic resistance, skin irritation and lack of novel therapy. Light and vacuum devices, also known as photopneumatic therapy, have been shown promising as a generally well-tolerated adjunctive treatment of acne vulgaris. We conducted a clinical study using such device to assess the efficacy and safety as an adjunctive treatment of acne in Taiwan Residents patients. Twenty patients received six sequential treatments every one to two weeks in the facial region. A 4 × 4 cm2 area on cheek was chosen as a control area and was not treated with photopneumatic device. Safety parameters and adverse events were recorded. VISIA Complexion Analysis System was used for image analysis on the improvement of four parameters, namely, pigmentation, pore reduction, redness and porphyrin levels. There was an overall improvement in pigmentation, pore size, redness and porphyrin levels on treatment areas. The treatment areas showed statistically significant improvement (p < 0.05) in pigmentation and pore sizes compared with the control areas using paired samples T-test. Mild and self-limiting localized adverse events, mostly focal petechiae or mild irritation, were reported. Our study has demonstrated that photopneumatic therapy is an effective, safe and relatively well-tolerated procedure in Taiwan Residents acne patients.展开更多
