BACKGROUND: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. METHODS: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index (MEPI). RESULTS: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final follow-up (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. CONCLUSIONS: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

2.Astigmatic Changes and Clinical Outcomes after Scleral Fixation of IOL.
Journal of the Korean Ophthalmological Society 2014;55(10):1452-1459
PURPOSE: To evaluate the clinical outcomes, complications and surgically induced astigmatism (SIA) after scleral fixation in patients with intraocular lens (IOL) or crystalline lens dislocation. METHODS: The present study retrospectively investigated the postoperative best corrected visual acuity (BCVA), refractory change, corneal astigmatism, clinical outcomes, and influencing factors of SIA in 57 eyes of 55 patients with a follow-up of 6 months after the IOL scleral fixation. RESULTS: In comparison of preoperative and postoperative 6 months, BCVA, spherical equivalent and astigmatism were significantly improved but corneal astigmatism was not and SIA (diopter, D) improved from 2.10 +/- 1.88 D to 0.86 +/- 0.73 D (p = 0.002). 4 eyes having redislocation were repositioned and 4 eyes having tilted IOL, 6 eyes having elevated intraocular pressure, 3 eyes having exposure scleral knots, 1 eye having endophthalmitis, and 1 eye showing macular edema were observed. At postoperative 3 months, the SIA of a large incision size (>3 mm) and small incision size (< or =3 mm) was significantly differented (p = 0.041). According to the location of scleral fixation, SIA at postoperative 1 month was significantly different but, was not different at postoperative 6 months. CONCLUSIONS: Surgical management of dislocated IOLs or crystalline lens resulted in significant improvement of visual acuity and absence of influencing SIA factors. However, location of scleral fixation and small incision size influenced corneal astigmatism.

Objective:
The present study aimed to analyze the correlation between platelet-to-lymphocyte ratio (PLR) and platelet-to-neutrophil ratio (PNR) with prognosis of patients who underwent mechanical thrombectomy (MT).
Methods:
A total of 432 patients was included, PLR and PNR were calculated from laboratory data on admission. Prognosis was evaluated with a modified Rankin Scale at 3 months after MT. Using receiver operating characteristic (ROC) analysis, optimal cutoff values of PLR and PNR were identified to predict the prognosis after MT. Multivariate analyses were performed to identify the relationship of PLR and PLR with prognosis of MT.
Results:
Patients with favorable outcomes had a lower mean PLR (135.0, standard deviation [SD] 120.3) with a higher mean PNR (47.1 [SD] 24.6) compared with patients with unfavorable outcomes (167.6 [SD] 139.3 and 35.4 [SD] 22.4) (p<0.001 and <0.001, respectively). In ROC analyses, the optimal cutoff value of PLR and PNR to predict the 3 months prognosis were 145 and 41, respectively (p=<0.001 and p=0.006). In multivariate analysis, PLR less than 145 (odds ratio [OR] 1.29, 95% confidence interval [CI] 1.06–2.06; p=0.016) and PNR greater than 41 (OR 1.22, 95% CI 1.10–1.62; p=0.022) were predictors of favorable outcome at 3 months.
Conclusions
In patients with MT, PLR and PNR on admission could be predictive factors of prognosis and mortality at 3 months. Decreased PLR and increased PNR were associated with favorable clinical outcome 3 months after MT.
