Objective The objective of the present research is to formulate solid lipid nanoparticles (SLN) of CH to improve its oral bioavailability.Methods Cinnacalcet hydrochloride (CH) exhibits poor oral bioavailability of 20 to 25% because of low aqueous solubility and first pass metabolism. The SLN formulations were optimized using Box-Behnken Design. SLN formulation was prepared using hot homogenization technique followed by ultra-sonication and evaluated. The optimized SLN formulation was lyophilized to improve the stability of the formulation further.Results Compritol 888 ATO (COM), Soya lecithin (SL) and poloxamer 188 (POL) were selected as lipid, surfactant and co-surfactant respectively. For optimistaion, the desirable goal was fixed for variour responses vis-a-vis entrapment efficiency (EE), particle size (PS) and (time taken for diffusion of 85% drug) T85%. The optimized single dose of SLN obtained using BBD consisting of 30 mg of CH, 100 mg of COM, 150 mg of SL and 0.1% w/v of POL. The pharmacokinetic study revealed that optimized SLN and lyophilized SLN were found to increase the oral bioavailability nearly two times compared to an aqueous suspension of pure drug.Conclusion Thus lyophilized SLN formulation explicated the potential of lipid-based nanoparticles as a potential carrier in improving the oral delivery and stability of CH.Background There is a paucity of literature exploring the impact of smoking on short-term complications, readmissions, and reoperations after elective upper extremity surgery using a large multicenter national database. We hypothesized that smokers will have an increased rate of complications, readmissions, and reoperations compared with a cohort of nonsmokers undergoing elective upper extremity surgery. Methods Patient data were collected from the American College of Surgeons National Surgical Quality Improvement Program database between the years 2012 and 2017. Patients were included if they underwent elective surgery of the upper extremity using 338 predetermined Current Procedural Terminology codes. The data collected were divided into patient demographics, comorbidities, perioperative variables, and 30-day complications. Current smoking status was defined as smoking within 1 year prior to surgery. The incidence of surgical complications, reoperations, and readmissions was compared between the 2 cohorts uropriately counsel patients on outcomes and complications given the elective nature of upper extremity surgery.Background Osteochondral lesions of the talus (OLT) often require advanced imaging if they prove to be refractory to preliminary microfracture. Orthopedic surgeons may misinterpret the size and morphology of the OLT when evaluating through conventional methods. learn more The purpose of this study was to evaluate MRI as a modality for calculating true-volumes and compare its utility to that of CT true-volume and conventional methods of measuring lesion size. Methods With IRB approval, an institutional radiology database was queried for patients with cystic OLT that had undergone and failed microfracture and had compatible CT and MR scans between 2011 and 2016. Five lesions, previously analyzed and described in the literature using CT true-volume, were selected. 10 orthopedic surgeons independently estimated the volume of these 5 OLT via standard MRI. Next, 3D reconstructions were created and morphometric true-volume (MTV) analysis measurements of each OLT were generated. The percent change in volumes from CT and MR was compared based upon MTVs determined from 3D reconstructive analysis. Results The volume calculated using conventional methods in CT and MR scans grossly overestimated the size by of the OLT by 285-864% and 56-374% respectively when compared to 3D true-volume analysis of those CT and MR scans. Conclusions This study demonstrates that true-volume is more accurate for calculating lesion size than conventional methods. Additionally, when comparing MRI and CT, thin slice CT true-volume is superior to MRI true-volume. True-volume calculation improves accuracy with CT and MRI and should be recommended for use in revision OLT cases. Levels of Evidence Level III Case control study.Neonatal idiopathic Bell's palsy is a very rare diagnosis with only a few previously published case reports of infants responding well to oral corticosteroid use. This trial therapy likely comes from adult data where clinical outcomes are improved following steroid use, although the data in childhood cases are equivocal. In this specific population of infants less then 28 days of age at presentation, the most common causes of Bell's palsy include congenital, birth trauma, and syndromic (likely with no indication for steroid treatment). In those with noncongenital Bell's palsy, infectious and structural causes should first be ruled out. In this article, we present the third known case report of a 16-day-old presenting with acute Bell's palsy with negative infectious workup and normal brain imaging. He was treated with a 7-day course of oral prednisone and had eventual resolution of symptoms.Importance Facial nerve paralysis is an unfortunate, yet relatively common sequela in the treatment of head and neck cancer. Static options for reanimation of the paralyzed midface and oral commissure offer limited quality-of-life improvement and may stretch over time. Reinnervation offers a prolonged recovery and may not be possible among patients with advanced cancer or in salvage situations. Objective To determine the improvement in resting tone and dynamic excursion gained by use of temporalis tendon transfer (TTT) and lengthening temporalis myoplasty (LTM) for facial nerve reanimation among patients undergoing oncologic head and neck cancer surgery. Design, Setting, and Participants We present the largest series of primary and secondary TTT operations with prolonged photographic and video-based data with analysis enabled by FaceGram open-source quantitative methodology. This was achieved using preoperative and postoperative digital photographs of each patient at rest and full smile excursion. Using the Jd oral commissure vertical and horizontal positions at rest, respectively. The average postoperative follow-up was 11.4 months (95% CI 5.6-14.11). In addition, when compared with patients treated with postoperative radiation therapy (9 patients), those who received preoperative radiation (15 patients) had a significant improvement in the resting vertical height of the affected side (mean 5.32 mm (p less then 0.05, 95% CI 0.06-10.57)). Conclusions and Relevance These findings encourage the use of TTT/LTM for facial nerve paralysis in appropriately selected head and neck oncologic patients.
