In another patient, medial suture ruptures occurred 4 months after surgery with type II acromioclavicular joint dislocation recurrence but with scarce symptoms and full recovery to sport activity. Clavicle osteolysis was observed in four patients. Cosmetics of the arm were judged as excellent in 39/41. All patients, except two, were satisfied with the final result. CONCLUSIONS The kite technique is a safe and reproducible arthroscopic procedure to treat acute ACJD. In daily clinical practice, due to the excellent results and the low complication rate, this technique might be considered by surgeons when operative treatment of an acute acromioclavicular joint dislocation is planned. LEVEL OF EVIDENCE IV.PURPOSE To evaluate tunnel widening and its relationship in loss of reduction and clinical outcomes in patients undergoing anatomic coracoclavicular ligament reconstruction (ACCR) using free tendon grafts for chronic acromioclavicular (AC) joint injuries. METHODS A retrospective chart review was performed on patients undergoing ACCR for type III-VI AC joint injuries between January 2003 and December 2017. For radiographic analysis, pre- and post-operative coracoclavicular distance (CCD) and tunnel width of the medial and lateral clavicular bone tunnel were measured at the earliest (EPO) and latest postoperative follow-up (LPO). To determine the clinical relevance of improvement in clinical outcome score (American Shoulder and Elbow Surgeons score) substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) thresholds were used. RESULTS Twenty-four patients with a mean clinical follow-up of 37 ± 35 months (mean age 44.7 ± 13.4) were included in the study. Both the medial (5.6 ± 0.2 mmEPO-6.6 ± 0.7 mmLPO;p less then 0.001) and lateral (5.6 ± 0.5 mmEPO-6.8 ± 1 mmLPO; p less then 0.001) clavicular bone tunnel showed significant widening from EPO to LPO. There was a significant loss of reduction at LPO (CCDLPO 10.1 ± 4 mm) compared to EPO (CCDEPO 6.2 ± 3.8 mm) (p less then 0.001). No significant correlation between loss of reduction and medial (p = 0.45; r = - 0.06) or lateral (p = 0.69; r = - 0.06) tunnel widening was found. Alterations in tunnel width were shown having no influence on clinical outcomes. CONCLUSION Patients who underwent ACCR using a free tendon graft for the treatment of chronic type III-VI ACJ injuries showed significant clavicular bone tunnel widening during the postoperative course. No correlation between tunnel widening and loss of reduction was shown with radiographic findings having no influence on clinical benefit and satisfaction. STUDY DESIGN Case Series; Level of evidence, IV.OBJECTIVE End-stage renal disease patients with vein diameter of ≤2.2 mm can undergo autogenous arteriovenous fistula (AVF) formation with the acceptable results. METHODS This observational retrospective study of prospectively collected data analyzed end-stage renal disease patients with a vein diameter of ≤ 2.2 mm, who underwent AVF formation at Shifa International Hospital Islamabad from January 2009 to December 2017. The fistulae were observed for immediate success and maturity at 3 months. The chi-square test was used to determine the effect of vein diameter on final maturity. All data were analyzed using SPSS. RESULTS The total number of patients with vein diameter of ≤2.2 mm was 38, with a mean age of 46.76 ± 12.790 years. Vein diameters ranged from 1.6 to 2.2 mm. Immediate success was observed in 35 (92.1%) cases. Veins of 31 (81.6%) patients showing maturity at 3 months and were used for hemodialysis. The overall success rate for the small caliber veins was 82%. CONCLUSION Although end-stage renal disease patients present late with very small diameter veins, these veins should still be accommodated for permanent vascular access, because their maturity rates are still acceptable, even though these are lower than those of patients with adequate sized veins.In this study, the photodegradation of organophosphorus (OPs) pesticides in the honey medium was evaluated under sunlight irradiation. Some of the 22 samples collected at different sites contained OPs pesticides (Methyl parathion, Coumaphos and Fenitrothion) with an average of 8 ng/g. Moreover, three samples were found with pesticide residue levels exceeding the maximum residue limits (MRL ≥ 50 ng/g) imposed by the standard water (WHO). Gas chromatography (GC) combined with a tritium electron capture detector system was used for the analysis of OPs pesticides in honey. Total degradation of the Methyl parathion was obtained in less than 60 min of irradiation. Moreover, the elimination of the other OPs found in the samples was also effective with a rate of 85% for Coumaphos and Fenitrothion after 50 min of sunlight irradiation. The kinetics of the photodegradation reaction of all OPs pesticides studied followed a pseudo-first order model.BACKGROUND Currently, there are no recommendations regarding the minimum duration of in-hospital monitoring after transfemoral (TF) transcatheter aortic valve replacement (TAVR) and practices are extremely heterogeneous. selleck chemicals llc We, therefore, aimed to evaluate length of stay (LOS) and predictive factors for late discharge after TF TAVR using data from the FRANCE TAVI registry. METHODS TAVR was performed in 12,804 patients in 48 French centers between 2013 and 2015. LOS was evaluated in 5857 TF patients discharged home. LOS was calculated from TAVR procedure (day 0) to discharge. The study population was divided into three groups based on LOS values. Patients discharged within 3 days constituted the "very early" discharge group, patients with a LOS between 3 and 6 days constituted the "early" discharge group, and patients with a length of stay > 6 days constituted the "late" discharge group. RESULTS The median LOS was 7 (5-9) days and was extremely variable among centers. The proportion of patients discharged very early, early, and late was 4.4% (n = 256), 33.7% (n = 1997), and 61.9% (n = 3624) respectively. Variables associated with late discharge were female sex, co-morbidities, major complications, self-expandable valve, general anesthesia, and a significant center effect. In contrast, history of previous pacemaker was a protective factor. The composite of death and re-admission in the very early and early versus late discharge groups was similar at 30 days (3.3% vs. 3.5%, p = 0.66). CONCLUSIONS LOS is extremely variable after TF TAVR in France. Co-morbidities and complications were predictive factors of late discharge after TAVI. Interestingly, the use of self-expandable prosthesis and general anesthesia may also contribute to late discharge. Our results confirm that early discharge is safe.
