title: Clinical time and postoperative sensitivity after use of bulk-fill (syringe and capsule) vs. incremental filling composites: a randomized clinical trial

description: Abstract The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or capsules). A total of 295 posterior restorations were placed according to the following groups: SETB – self-etch/bulk-fill in syringe; SETC – self-etch/bulk-fill in capsules; SETI – self-etch/incremental; SEEB – selective enamel-etching/bulk-fill in syringe; SEEC – selective enamel-etching/bulk-fill in capsules; and SEEI – selective enamel-etching/incremental. Clinical time was assessed by a reason (s/mm3) between the total volume of resin inserted and the total time required to perform the restorations. Postoperative sensitivity was evaluated using two scales (Numeric Rating Scale and Visual Analogue Scale). Mean clinical time results, analyzed by Wald’s Chi-square, showed significant statistical differences among all groups (p&lt;0.001), indicating that the restorative strategy affected the time required for the restoration. A generalized estimating equation model statistical analysis, performed to compare postoperative sensitivity, showed that neither the restorative technique, the adhesive strategy nor the presentation mode of the bulk-fill composite affected the overall risk of postoperative sensitivity (4.06 [2.22–6.81]). The use of bulk-fill composite, presented in capsules or syringes, is less time consuming and does not increase the risk or intensity of postoperative sensitivity relative to the traditional incremental technique.

title: Post-laser in situ keratomileusis interface Arthrographis kalrae keratitis

description: ABSTRACT We describe a case of keratomycosis caused by Arthographis kalrae after excimer laser keratomileusis. A 38-year-old female developed stromal keratitis eight weeks after refractive surgery. She developed severe corneal stromal infiltration and mild anterior segment inflammation, which could not be treated with topical voriconazole 1%, but topical natamycin 5% ameliorated her condition. A reactivation of keratomycosis symptoms was observed; therefore, longer treatment was administered to the patient. It has been reported that A. kalrae keratomycosis is associated with exposure to soil and contact lens usage. However, the patient, who lived in a rural location, was neither involved in gardening activities nor had a history of wearing contact lenses. This is the first case of post-refractive A. kalrae keratomycosis.

title: Upper eyelid contour symmetry measurement with Bézier curves

description: ABSTRACT Purpose: The purpose of the present work is to measure the interocular upper lid contour symmetry using a new method of lid contour quantification. Methods: The Bézier curve tool of the Image J software was used to extract the right and left upper eyelid contours of 75 normal subjects. Inter-observer variability of 29 right lid contours obtained by two independent observers was estimated using the coefficient of overlap of two curves and an analysis of the differences of the contour peak location. A two-way analysis of variance was used to test the mean value of the coefficient of overlap of the right and left contours in males and females and lid segments. The same analysis was performed to compare the location of the contour peak of the right and left contours. Results: The coefficient of contour overlap obtained by independent observers ranged from 93.5% to 98.8%, with a mean of 96.1% ± 1.6 SD. There was a mean difference of 0.02 mm in the location of the contour peak. Right and left contour symmetry did not differ between females and males and was within the range of the method variability for contour overlap and location of the contour peak. Conclusions: The upper eyelid contour is highly symmetrical. Bézier lines allow a quick and fast quantification of the lid contour, with a mean inter-observer variability of 3.9%.

title: Fifteen years of experience with frontalis suspension using polytetrafluoroethylene (Gore-Tex®) suture in blepharoptosis repair

description: ABSTRACT Purpose: To review the outcomes of frontalis suspension surgeries with the use of polytetrafluoroethylene in patients with blepharoptosis. Methods: A retrospective observational study analyzed the outcomes of frontalis suspension surgeries performed in a single institution from 2003 to 2018. All procedures were performed with closed incision and single pentagon techniques. Outcomes were classified as satisfactory or unsatisfactory, with satisfactory defined as a margin reflex distance of &gt;3 mm and &lt;1 mm between eyelids and unsatisfactory as hypocorrection, surgical complications, and asymmetry. Results: We included a total of 76 eyelids from 52 patients in our study. Within a mean postoperative follow-up of 16.8 ± 18.5 months (range, 3-95), 59 (77.6%) eyelids had a satisfactory outcome, and 17 (22.4%) were unsatisfactory (8 cases of asymmetry, 3 granulomas, 3 suture extrusions, 2 abscesses, and 1 case of cellulitis). Nine eyelids from the unsatisfactory group required reoperation. Among the patients with a follow-up of ³12 months (38 surgeries), lasting results were observed in most eyelids, except for 2 late-onset suture extrusions. Conclusion: The use of polytetrafluoroethylene in frontalis suspension surgery was shown to be predictable, safe, and lasting. Our findings support previous studies that have shown adequate functional results and low complication rates.

title: Prosthesis-socket volume imbalance and dermofat graft rehabilitation in patients with an anophthalmic socket

description: ABSTRACT Purposes: To identify problems caused by prosthesis-socket volume imbalances in anophthalmic sockets; and to evaluate rehabilitation with dermofat graft as a solution. Methods: We retrospectively reviewed medical records of patients operated in our clinic (between May 2011 and June 2016) with dermofat grafts to treat anophthalmic socket-related problems. During the preoperative examinations, ophthalmologists recorded the presence of eyelid problems due to the socket volume deficit, upper and lower fornix deficiency, deepening in the upper eyelid sulcus, epiphora and secretion, lower eyelid laxity, ptosis, entropion, and ectropion. Following the surgical repair, new prosthesis suitable for the resulting socket area were implemented for all the patients. The mean follow-up period was 27.42±16 months (ranging from 10-62 months). On the last control examinations, ophthalmologists recorded solved and unsolved socket problems that were present preoperatively. Results: We included 16 men and 5 women in this study. The mean age was 38.3 ± 18.4 years (range, 5-75 years). The mean duration of preoperative prosthesis use was 9.4 ± 6.8 years (range, 1-30 years). Preoperatively, 7 patients had only orbital volume deficits, and 14 had socket volume displacements in addition to the volume deficits. After the dermofat graft implantations, the remaining deficits were corrected during another surgical session: 6 patients underwent ptosis corrections, 5 lateral canthal suspensions, 5 lower fornix with mucosal graft formations, and 2 upper fornix formations with mucosal grafts. All patients were able to use prosthesis postoperatively. Conclusion: The use of dermofat grafts to correct anophthalmic socket problems caused by orbital volume deficits or volume displacements is an effective, reliable, and reproducible surgical method.

title: Morphological and molecular characterization of Puccinia kuehnii, the causal agent of sugarcane orange rust, in Cub

description: ABSTRACT Sugarcane orange rust caused by Puccinia kuehnii has recently become an important disease in sugarcane crops and its spread is causing great concern to growers. In this study, we analyzed spores from symptomatic orange rust sugarcane leaves collected in multiple locations in Cuba in a 4-year-period in order to characterize morphological traits of P. kuehnii, establish an adequate molecular technique to characterize it, and determine its infection court in sugarcane. Orange rust caused by P. kuehnii was confirmed by polymerase chain reaction (PCR) and morphological characterization. AFLP markers detected high diversity in P. kuenhnii samples. Sequencing of rDNA regions, as expected, did not reveal differences and SSR markers designed for P. melanocephala could not be transferred to P. kuehnii. In addition to stomata, entry through prickles was also detected as a new infection court in sugarcane. Although the presence of pustules on the adaxial leaf surface was frequently detected, no clear correlation between this presence and density of stomata and/or prickles was found.

title: Effect of surface roughness and lubrication on the friction coefficient in deep drawing processes of aluminum alloy aa1100 with fem analysis

description: ABSTRACT Friction between the interface workpiece and tooling has considerable importance in sheet metal forming operations; an accurate description of the friction is necessary to analyze and design new workpieces and tooling. This work suggests a methodology to determine and evaluate the mean coefficient of friction (COF) using the Finite Element Method (FEM) through Dynaform for the aluminum alloy AA1100. The results indicate that this methodology is consistent with reality. It is also observed that the software tends to diverge from the measured results because the software considers the COF to be constant along the process. Despite this trend, the greatest distance between the maximum drawing force given by the measurement and the numeric simulation was not high: it was approximately 6%. Workpiece strain measurements were collected to compare with the numerical simulation results, and it was observed that they are generally in agreement.

title: Carnitine analysis in pterygium

description: ABSTRACT Purpose: The aim of the present study was to measure the free carnitine and acylcarnitine levels in pterygium tissue and normal conjunctival tissue at the metabolomics level using tandem mass spectrometry. Methods: In this prospective, clinical randomized study, pterygium tissues and normal conjunctival tissues taken during pterygium excision with autograft were compared regarding their free carnitine and acylcarnitine profiles. After tissue homogenization, carnitine levels were measured using tandem mass spectrometry. The data were statistically analyzed with the Wilcoxon signed-rank test. Results: Pterygium and normal conjunctival tissue samples from a single eye of 29 patients (16 females, 13 males; mean age, 54.75 ± 11.25 years [range, 21-78 years]) were evaluated. While the free carnitine (C0) level was significantly high in the pterygium tissue (p&lt;0.001), acylcarnitine levels were significantly high in some esterized derivatives (C2, C5, C5:1, C5DC, C16:1, C18, methylglutarylcarnitine) (p&lt;0.05). No statistically significant difference was determined for the other esterized derivatives (p&gt;0.05). Conclusion: That the carnitine levels in pterygium tissue were higher suggests that acceleration of cell metabolism developed secondary to chronic inflammation and the premalignant characteristics of pterygium tissue. High carnitine levels may also effectively suppress the apoptosis process. The data reported in our study indicate that further, more extensive studies of the carnitine profile could help clarify the pathogenesis of pterygium.

title: Influence of shielding gas composition on the residual stresses of DP600 steel joints welded by GMAW process

description: ABSTRACT The automotive industry has been investing in new manufacturing processes that improve productivity without loss of quality. However, the presence of residual stress (RS), generated in all manufacturing processes, is one of the major problems encountered in the metalworking industry, since these can add up to external loading stresses and cause catastrophic failures in equipment and components. Since welding is one of the most widely used manufacturing processes, it is necessary to know how the welding parameters impact on the nature and magnitude of the residual stresses generated. The shielding gases are used in some welding processes and can be influence the conductivity of the electric arc, which can be affected the residual stresses behavior in the welded joints. In this work an experimental study was carried out about the influence of the percentage of CO2 on the argon-based shielding gases in the residual stresses generated on joints of high strength steel DP600 welded by GMAW process (widely used in the automotive industry). The residual stresses were measured by X-ray diffraction by the sin2ψ method. An assessment of the microstructural morphology by optical microscope (OM) was made. The results showed that the residual stresses have a tensile nature, of the order of 120 MPa, in all samples, which used shielding gas with a lower percentage of CO2.
