3% in LCP group (p = 0.40). Moreover, older age, fracture comminution and compression plate fixation predispose to neck shortening. Conclusion Dynamic limited axial compression by SMBP or LCP fixation was effective to improve the functional outcome of patients with Pauwels type-3 femoral neck fractures.Background and objectives Sugammadex is a modified gamma-cyclodextrin that reverses the effects of aminosteroidal neuromuscular blocking agents. Tanzisertib molecular weight Likewise, some steroid molecules, such as toremifene, fusidic acid, and flucloxacillin, can also be encapsulated by sugammadex. Methylprednisolone, which is a synthetic steroid used commonly for airway oedema prophylaxis, can also be encapsulated by sugammadex. The objective of this study was to compare the recovery times of sugammadex for reversing rocuronium-induced moderate neuromuscular blockade in those who received intraoperative 1 mg.kg-1 methylprednisolone or saline. Method This single-centered, randomized, controlled, prospective study included 162 adult patients undergoing elective ear-nose-throat procedures (aged from 18-65, an ASA physical status I-II, a BMI less than 30 kg.m-2, and not taking steroid drug medication) with propofol, remifentanyl, rocuronium and sevoflurane. Neuromuscular monitoring was performed using calibrated acceleromyography. The Control Group (Group C) received 5 mL of saline, while the Methylprednisolone Group (Group M) received 1 mg.kg-1 of methylprednisolone in 5mL of saline just after induction. After the completion of surgery, regarding the TOF count, two reappeared spontaneously and 2 mg.kg-1 sugammadex was administered to all patients. Recovery of the TOF ratio to 0.9 was recorded for both groups, and the estimated recovery time to reach a TOF ratio (TOFr) of 0.9 was the primary outcome of the study. Results Median time to TOFr = 0.9 was for 130.00 s (range of 29-330) for Group C and 181.00 s (100-420) for Group M (p less then 0.001). The differences between the two groups were statistically significant. Conclusion When using 2 mg.kg-1 of sugammadex to reverse rocuronium-induced neuromuscular blockade in patients who received 1 mg.kg-1 of intraoperative methylprednisolone, demonstrated delayed recovery times.Background and objectives The lumbar plexus block (LPB) is a key technique for lower limb surgery. All approaches to the LPB involve a number of complications. We hypothesized that Chayen's approach, which involves a more caudal and more lateral needle entry point than the major techniques described in the literature, would be associated with a lower rate of epidural spread. Method We reviewed the electronic medical records and chart of all adult patients who underwent orthopedic surgery for total hip arthroplasty (THA) and hip hemiarthroplasty due to osteoarthritis and femoral neck fracture with LPB and sciatic nerve block (SNB) between January 1, 2002, and December 31, 2017, in our institute. The LPB was performed according to Chayen's technique using a mixture of mepivacaine and levobupivacaine (total volume, 25 mL) and a SNB by the parasacral approach. The sensory and motor block was evaluated bilaterally during intraoperative and postoperative period. Results A total number of 700 patients with American Society of Anesthesiologists (ASA) physical status I to IV who underwent LPB met the inclusion criteria. The LPB and SNB was successfully performed in all patients. Epidural spread was reported in a single patient (0.14%; p less then 0.05), accounting for an 8.30% reduction compared with the other approaches described in the literature. No other complications were recorded. Conclusions This retrospective study indicates that more caudal and more lateral approach to the LPB, such as the Chayen's approach, is characterized by a lower epidural spread than the other approach to the LPB.Objectives Dental plaque build-up on the cervical area adjacent to gingival margins is a trigger factor for secondary caries around restored root caries lesions. Dimethylaminohexadecyl methacrylate (DMAHDM) and amorphous calcium phosphate nanoparticles (NACP) impart anti-caries effect by reducing the bacterial growth and releasing high concentrations of calcium and phosphate ions, respectively. The present study explored the optimization and formulation of dental composite with increased concentration of DMAHDM combined with NACP and its effect on mechanical behavior and antibacterial response. Methods DMAHDM was incorporated into dental composite formulation at 3% and 5% with 20% NACP fillers. Mechanical properties were assessed by flexural strength and elastic modulus. The cationic charge density of the samples was determined using fluorescein staining assay. A human saliva-derived microcosm biofilm model was used to assess antibacterial response via colony-forming units, metabolic activities, lactic acid pdary caries around the restored root caries lesions.Chagas disease is a neglected parasitosis caused by the protozoan parasite Trypanosoma cruzi. This infection is present in most Latin American countries, although, due to migratory movements, it is a growing cause for concern in non-endemic countries. The only two drugs currently available for its treatment-benznidazole and nifurtimox-were marketed 50 years ago. While they are very effective for acute and recent infection, and for the prevention of maternofoetal transmission, their efficacy declines in people who have chronic infection, especially those older than 18 years of age. In the presence of visceral involvement, parasiticidal treatment is of little or no value. The safety profile of both drugs is far from ideal, with frequent adverse events and high rates of drug discontinuation, mainly in adults. So far, new drugs and new strategies have not been shown to improve the results of the current nitroimidazoles, although the results are promising. In this review, we focus on the aspects that allow clinicians to make the best use of currently available drugs. In addition, we discuss new therapeutic options and ongoing research in the field.Objective To evaluate the treatment outcomes of an alternative retrograde superselective ophthalmic artery catheterization (intra-arterial chemotherapy [IAC]), while treating retinoblastoma patients. Methods A retrospective review of IAC for 21 treatment-naïve eyes (21 patients, primary group) and 10 eyes of previously treated 9 patients (secondary group). Statistical analysis was performed using Number Cruncher Statistical System 2007, Kaplan-Meier survival analysis, and Fisher's exact test. Results Total fluoroscopy time ranged from 3 to 12 minutes. Globe salvage was 71.4% (15/21 eyes) and 80% (8/10 eyes) in the primary and secondary groups, respectively. Globe salvage rates were recorded as 100%, 100%, 70%, and 0% for group B, C, D, and E patients, respectively. Conclusions Retrograde IAC is effective in tumour control with shorter fluoroscopy time and acceptable complication rates both for naïve and treated patients. Furthermore, controlling retinoblastoma in advanced group D eyes was efficacious.
