Patients with haemophilia are prone to haemophilic arthropathy (HA). For end-stage HA, total knee arthroplasty (TKA) is an effective procedure. However, limited data were available regarding complications of TKA in HA patients.

To provide comprehensive comparisons of TKA complications among patients with osteoarthritis (OA), rheumatoid arthritis (RA) or HA.

The present study was a single-surgeon cohort study including patients who underwent TKAs for OA, HA or RA from January 1997 to December 2017. The information of patients was extracted from medical records and follow-up database. The primary outcome was complications. Potential risk factors of complications in HA patients were also evaluated.

A total of 1515 patients with 2083 TKAs were selected following the criteria. see more The overall complication rate in the HA group was 21.79%, which was much higher than the OA or RA group (7.08% and 8.70%, respectively, P<.05). The dominate complications were prosthetic loosening and wound dehiscence. For HA, more complications occurred in the period more than 1year after TKA when compared with OA (33.33% vs 11.43%, P=.028). Among the potential risk factors, patients with haemophilia B and severe haemophilia had significantly higher complication rates (P<.05 for both).

When compared with OA or RA, HA patients had different characteristics on complications, including the higher complication rate, different complication distribution and later occurring time. In HA patients who underwent TKA, haemophilia B and severe haemophilia were risk factors of complications which should be paid more attention to.

The nascent market of cosmeceutical options provides a potentially safer and efficacious alternative for treating these challenging conditions. These can be used alone or in combination with other established treatments. Many cosmeceutical products are thought to work through inhibition of tyrosinase, a key enzyme of melanogenesis. We discuss the mode of action and provide an up-to-date review of the underlying evidence base for the top 10 cosmeceutical products for hyperpigmentation and melasma. Possible safer and more efficacious cosmeceutical therapies we discuss include thiamidol, kojic acid, vitamin C, arbutin, retinol, nicotinamide, ferulic acid, resorcinol, licorice root extract, and soy.

This study aimed to investigate the effects of alcohol consumption (AC) on maxillofacial fractures caused by falls on a level surface (simple falls).

Patients with maxillofacial fractures caused by falls who visited the Oral and Maxillofacial Surgery Clinic from January 2006 to December 2016 were evaluated. Patients with simple falls were subdivided into those who fell with AC (Falls with AC) and those who fell without AC (Falls without AC).

Of 180 patients with falls with maxillofacial fractures, 155 had simple falls, and 25 patients had falls from a height. Of the simple falls, 52 were Falls with AC, and 102 were Falls without AC. Falls with AC were significantly more frequent in males (p = .0005). The average number of fracture lines in the mandible was significantly higher in Falls with AC (2.13 ± 0.99 [mean ± SD]) than in Falls without AC (1.76 ± 0.91) (p = .011). The average Facial Injury Severity Scale was significantly higher in Falls with AC (3.08 ± 1.43) than in Falls without AC (2.43 ± 1.29) (p = .007).

Falls with AC were associated with more severe maxillofacial fractures than Falls without AC.

Falls with AC were associated with more severe maxillofacial fractures than Falls without AC.A dicationic imidazolium salt is described and investigated towards its application for gene transfer. The polar head group and the long alkyl chains in the backbone contribute to a lipid-like behavior, while an alkyl ammonium group provides the ability for crucial electrostatic interaction for the transfection process. Detailed biophysical studies regarding its impact on biological membrane models and the propensity of vesicle fusion are presented. Fluorescence spectroscopy, atomic force microscopy and confocal fluorescence microscopy show that the imidazolium salt leads to negligible changes in lipid packing, while displaying distinct vesicle fusion properties. Cell culture experiments reveal that mixed liposomes containing the novel imidazolium salt can serve as plasmid DNA delivery vehicles. In contrast, a structurally similar imidazolium salt without a second positive charge showed no ability to support DNA transfection into cultured cells. Thus, we introduce a novel and variable structural motif for cationic lipids, expanding the field of lipofection agents.

Surgical aortic valve replacement (sAVR) is the ultimate therapy for severe aortic stenosis (AS) in suitable patients. Prognostic factors of sAVR are great interest in recent studies. Frontal QRS-T angle (fQRSTa) is a novel marker of ventricular repolarization abnormalities. In this study, we aimed to investigate the prognostic value of fQRSTa in patients with severe symptomatic AS undergoing sAVR.

A total of 372 patients with severe degenerative AS who underwent successful sAVR were included in this retrospective study. Then, patients were divided into two groups patients with narrow fQRSTa (≤90°) as group 1 and wide fQRSTa (>90°) as group 2. Perioperative and postoperative clinical evaluation and time of death were recorded from all subjects.

The incidence of total mortality was higher in patients with wider fQRSTa (13.8% [15]; 4.9% [9], P = .013) compared to patients with narrow fQRSTa. In multivariate logistic regression analysis, advanced age (odds ratio [OR] = 1.054; 95% confidence interval [CI] = 1.
