    Abstract A best evidence topic in general surgery was written according to a structured protocol. The clinical question addressed was: in adult patients with splanchnic vein thrombosis in acute pancreatitis, would administration of therapeutic anticoagulation be advisable considering the rates of vessel recanalization and bleeding complications? Four hundred twenty-four papers were found on Ovid Embase and Medline whilst 222 were found on PubMed using the reported literature search. From these, five articles represented the best evidence to the clinical question. The authors, publication dates, countries, patient groups, study outcomes, and results of these papers were tabulated. There were three systematic reviews with meta-analyses, one systematic review without meta-analysis and one randomized, retrospective study. The authors conclude that among patients with splanchnic vein thrombosis in the context of acute pancreatitis, therapeutic anticoagulation improved the rates of recanalization without increasing the risk of bleeding complications. However, there remains a need for randomized studies to address this clinical dilemma to further increase the quality of available evidence.

    Abstract Four contact models including Hertz, Jamari, Jeng-Wang and Weng-Tang-Zhou-Zhu were considered. To verify the results of contact mechanics, the indentation depth has been compared with spherical geometry. According to the obtained results, by comparing the spherical and elliptical geometries, the indentation depth for spherical geometry is higher than for the ellipsoidal geometry, due to the existence of eccentricity in elliptical contact models which does not exist in spherical geometry. Among the models, the Jeng-Wang and Weng-Tang-Zhou-Zhu are models that are based on the contact of a particle with the substrate. Based on the existing experimental work, Jeng-Wang is the most suitable model for being applied in particle-substrate contact point. The Hertz model has been developed from crowned cylinder equations in order to be implemented for ellipsoidal geometry, moreover the Jamari model investigates two ellipses in contact with each other. By comparing Jeng-Wang and Weng-Tang-Zhou-Zhu models it is obvious that Jeng-Wang has the highest indentation depth while for the Weng-Tang-Zhou-Zhu model it is the lowest. These trends happen for two contact points. Also four materials are compared, among which graphite and chromium have the highest and the lowest indentation depths, respectively. Finally based on the obtained results Jeng-Wang and Jamari are the most suitable contact models that can be implemented in the manipulation of ellipsoidal nanoparticles.

    Abstract A best evidence topic in general surgery was written according to a structured protocol, to address the question: in adult patients with perianal abscesses, should postoperative wound packing be undertaken considering the rates of pain experienced, wound healing and abscess recurrence? The literature search identified 159 papers on Ovid, Embase and Medline and 48 on PubMed. These were independently screened, and three articles were included in this review as these offered the best information to answer the question. One was a systematic review without meta-analysis, one was a randomised controlled trial and one was a multicentre observational study. Review of these articles led the authors to conclude that routine postoperative packing of perianal abscesses following incision and drainage is costly, associated with increased pain and confers no protection against recurrence of abscesses or formation of fistulae.

    Abstract Introduction: Arteriovenous malformation (AVM) leads to a direct connection between arterial and venous networks, in which capillary branches are not involved. Pelvic AVM is a benign and rare condition causing severe pain, hematuria, and rectal or vaginal bleeding.
    Case presentation: A 36-year-old woman presented with five months history of hematuria. Her medical history was unremarkable, and laboratory findings were all within normal ranges. Abdominopelvic computed tomography (CT) scan revealed a vascular mass in the left lateral pelvis that extended to the bladder neck and was suggestive of an AVM. The patient underwent a laparotomy for the resection of AVM. The first angiography revealed an AVM in the left internal iliac artery. The patient underwent embolization with coil and gel foam. The second angiography revealed complete obstruction of the left internal iliac artery due to multiple coils and AVM of the right internal iliac artery (RIIA), embolized with glue and lipiodol. A week later, venography revealed another left iliac vein malformation embolized with foam sclerotherapy. Forty days later, the third angiography revealed another AVM in the right iliac artery, embolized with three vials of polyvinyl alcohol (PVA). Following two months of follow-up, the symptoms did not return.
    Discussion: The present study reported a rare case of recurrent pelvic AVM causing painless hematuria in a female patient. The lesion was treated with several angioembolization sessions.
    Conclusion: Angioembolization is one of the main therapeutic options for AVM. Appropriate material should be precisely chosen for AVM embolization regarding the AVM's location, size, and condition.

    Abstract Background: Endophthalmitis, a potentially sight-threatening condition, remains a challenge for ophthalmologists worldwide. The endophthalmitis vitrectomy study (EVS) conducted in 1995 compared vitrectomy and intravitreal antibiotic injections to intravitreal antibiotic injections alone for acute post-cataract surgery and secondary intraocular lens endophthalmitis, setting treatment guidelines. However, the landscape of clinical practice has evolved considerably since then, raising questions about the applicability of EVS recommendations today.
    Summary: Recent studies have proposed that early and complete vitrectomy (CEVE) could potentially be an effective approach for managing endophthalmitis cases, irrespective of the initial visual acuity. However, it is important to note that the level of rigor in these recent studies may not match that of the EVS study, and as such, this assertion should be considered with caution. Furthermore, the EVS study exclusively focused on post-cataract surgery cases, leaving other endophthalmitis types, like post-intravitreal injection and post-traumatic endophthalmitis, without standardized treatment guidelines. Research exploring the role of early vitrectomy in these contexts yields mixed results, emphasizing the need for further investigation and well-designed prospective trials. Endogenous endophthalmitis, originating from systemic infections, adds complexity to the scenario. While early vitrectomy shows promise in specific cases, conflicting evidence necessitates comprehensive research.
    Key messages: This review underscores the necessity for tailored treatment strategies, supporting early vitrectomy when clinically indicated, and advocating for prospective trials to clarify its role in diverse endophthalmitis scenarios. As surgical techniques and antimicrobial therapies continue to advance, reevaluating treatment paradigms becomes crucial to enhance patient outcomes and protect ocular health.

    Abstract Purpose: To evaluate the repeatability of biometry and intraocular lens (IOL) power using Galilei G6 and to determine the agreement of its measurements with those of IOL Master 700 and IOL Master 500.
    Methods: Hundred mature cataract eyes were examined twice with Galilei G6 and the results were compared with those of other two devices. Axial length (AL), minimum (K1), maximum (K2), and mean keratometry, anterior chamber depth (ACD), white-to-white (WTW) diameter, lens thickness (LT), and the calculated IOL power were the studied parameters. The correlation coefficient, within-subject standard deviation (Sw), Bland-Altman method, and 95% limits of agreement (LoA) were used for statistical analysis.
    Results: The intraclass correlation coefficient (ICC) was above 0.9 for all indices, and the LoA ranged from a minimum of 0.08 mm for AL to a maximum of 0.50 D for K1. Sw also ranged between a minimum of 0.02 for AL, ACD, and WTW and a maximum of 0.13 for K1. In the Galilei G6-IOL Master 700 pair, the narrowest and widest LoA were calculated for AL (0.07 mm) and K2 (0.49 D), respectively. In the Galilei G6-IOL Master 500 pair, the narrowest and widest widths of LoA were calculated for AL (0.17 mm) and K2 (0.92 D), respectively. In the first pair, the LoA of IOL power (0.57 D) were the best for Haigis formula and in the second pair, the best agreement (LoA: 0.35 D) was observed for Holladay-1.
    Conclusion: Galilei G6 provided repeatable biometric measurements. The agreement between biometry and IOL power calculation was better in the Galilei G6-IOL Master 700 pair compared to the Galilei G6-IOL Master 500.

    Abstract Digoxin is cardiac glycosylated steroid like drug which is the fifth most commonly prescribed in US. Since the health of human population is largely determined by pharmacy they utilized, toxicity and side effects of pharmaceutics can put the safety of people in jeopardy and lead to some devastating impacts. Therefore, it is essential to detect and monitor small molecules like digoxin more meticulously. Although digoxin has positive inotropic and batmotropic impact on heart muscle, it has also negative chronotropic and dromotropic effect. The prescription dose of this drug is 1-2 ng/ml and more than 2.8 ng/ml of this medication cause toxicity. Hence, there is small variation between therapeutic and toxic dosage of digoxin. Abundant conventional methods have been introduced for digoxin monitoring such Liquid chromatography (LC), LC-MS, HPLC. However, they suffer expensive equipment, long lasting procedure and high limit of detection. Hence, various advance immunosorbent, biosensors and aptasensors have been introduced. The purpose of this review is limited to pointing convention methods drawbacks and introducing novel digoxin enzyme-linked or non-enzymatic immunosorbent assays, and biosensors paying special attention to their basic strategies and detection abilities. Future trends in Bio and immune sensors used for onset monitoring and detection of digoxin are also highlighted.

    Abstract Introduction: To investigate the long-term results of laser in situ keratomileusis (LASIK) in patients with one or more topographic indices outside the suggested range preoperatively.
    Methods: Patients who had conventional or femtosecond laser-assisted LASIK for myopia correction between 2011 and 2015, and had at least one preoperative corneal topographic index outside the suggested range were contacted for a follow-up examination. Ranges were based on the cutoffs suggested for subclinical keratoconus: thinnest pachymetry (TP) < 497.50 µm, maximum keratometry (Kmax) > 47.20 D, maximum 8 mm best-fit-sphere anterior elevation (MaxAE) > 9.50 µm, maximum 8 mm best-fit-sphere posterior elevation (MaxPE) > 20.50 µm, and Belin/Ambrósio enhanced ectasia display-total deviation (BAD-D) > 1.60.
    Results: Two hundred thirty patients (377 eyes) were enrolled; their mean age at baseline and at follow-up was 30.78 ± 8.16 and 9.06 ± 1.91 years, respectively. Mean ± SD was 484.36 ± 11.49 for TP (n = 133), 48.17 ± 0.83 for Kmax (n = 133), 16.33 ± 5.39 for MaxAE (n = 35), 27.87 ± 7.86 for MaxPE (n = 34), and 1.97 ± 0.36 for BAD-D (n = 162). Post-LASIK and suspected ectasia was found in one (0.26%) and two (0.53%) eyes, respectively. In the remaining 374, the efficacy and safety indices were 0.96 ± 0.14 and 1.01 ± 0.08, respectively. Uncorrected distance visual acuity (UDVA) was not reduced in any eyes, and corrected distance visual acuity (CDVA) was reduced one line in 1.9% of the cases; 79.9% of the cases were emmetropic. The long-term changes in UDVA, CDVA, and spherical equivalent were not different between groups with one, two, or three out-of-range topographic indices (all P > 0.05).
    Conclusion: A single out-of-range topographic index is not a strong predictor for postoperative complications, and one should consider the combination of topographic and clinical findings, or the pattern they create in tandem. Developing a scoring system that would take a combination of indices and topographic patterns may help improve the predictive accuracy of these indices.
