    No full text
    Study Design: Modified Delphi study. Objective: Adult spinal deformity (ASD) is an increasingly recognized condition, comprising a spectrum of pathologies considerably impacting patients' health and functional status. Patients present with a combination of pain, disability, comorbidities and radiological deformity. The study aims to propose a systematic approach of gathering information on the factors that drive decision-making by developing a patient profile. Methods: The present study comprises of 3 parts. Part 1: Development of prototype of patient profile: The data from the Core Outcome Study on SCOlisis (COSSCO) by Scoliosis Research Society (SRS) was categorized into a conceptual framework. Part 2: Modified Delphi study: Items reaching >70\% agreement were included in a 4 round iterative process with 51 panellists across the globe. Part 3: Pilot testing-feasibility: Content validity and usability were evaluated quantitatively. Results: The profile consisted of 4 domains. 1. General health with demographics and comorbidities, 2.Spine-specific health with spine related health and neurological status, 3. Imaging with radiographic and MRI parameters and 4. Deformity type. Each domain consisted of 1 or 2 components with various factors and their measuring instruments. Profile was found to have an excellent content validity (1-CVIr 0.78-1.00Ave-CVI 0.92) appropriateness, relevance and usefulness. Conclusions: The present study, is first to provide a universally applicable multimodal ASD patient profile to methodically describe patients. Physicians are encouraged to assess ASD patients holistically using this profile and not just based on radiographic findings

    Introduction Interstitial cystitis (IC) is a chronic bladder inflammation with unknown etiologies that impairs the quality of life of patients. We aimed to investigate the efficacy of dimethyl sulphoxide (DMSO) use in the cocktail therapy in IC patients. Material and methods Patients treated with intravesical cocktail therapy which contained a mixture of 10 mL of bupivacaine, 1 mL of heparin, and 9 mL of sodium bicarbonate, was introduced to Group 1, and, 25 mL of DMSO was added to this cocktail and introduced to Group 2. Statistical analyses between groups were assessed by Turkish validated O'Leary Sant score composed of IC Symptom Index (ICSI) and IC Problem Index (ICPI), visual analog scale (VAS) score, and short form-36 (SF-36) questionnaire in the baseline versus post-instillation week 6, month 6, and month 12, comparatively.Results A total of 62 patients (58 women and 4 men) with a median age of 52 (28-76) years were included. Baseline versus post-instillation 6th week of ICSI and ICPI scores were 15 +/- 3.4 vs 7.4 +/- 2.9 and 12.6 +/- 2.8 vs 6.1 +/- 2.7, respectively (p <0.001 and <0.001, respectively). VAS scores of Group 2 were statistically significantly lower than that of Group 1 in the post-instillation month 6 (p = 0.03) whereas, the baseline of VAS scores were similar.Conclusions Intravesical cocktail therapy is an effective and reliable treatment method and can be safely applied with or without DMSO. Adding DMSO to cocktail therapy provides a further decrease in VAS score in the post-instillation month 6

    Purpose The aim of this study is to investigate the correlation between the magnetic resonance imaging (MRI) and intraoperative findings of deep infiltrating endometriosis using the \#ENZIAN score. Methods This retrospective study included 64 patients who underwent surgery for deep infiltrating endometriosis between January 2017 and August 2020. Preoperative abdominopelvic MRI assessment was evaluated and scored using the \#ENZIAN classification. Operative scores were considered the gold standard, and the sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of MRI for each category were calculated. Results MRI has higher sensitivity and specificity in showing the lesions of the compartments O (ovarian lesions), A (rectovaginal septum and posterior vaginal fornix), and B (uterosacral ligaments and parametrium) (100-100\%, 100-100\%, and 97-100\%, respectively, p < 0.001) compared to the other compartments. The lowest sensitivity, specificity, accuracy, and PPV of the MRI was found in compartment P (14\%, 76\%, 70\%, and 7\%, respectively). Conclusion We demonstrated that the \#ENZIAN classification in MRI reports has significant sensitivity and specificity in compartments A, B (uterosacral ligaments and parametrium), and O. Furthermore, the determination of peritoneal lesions via MRI is inadequate.1JAN215-22030

    Hydatid disease of the brain and spine

    No full text
    Hydatid disease of the central nervous system is relatively rare and comprises about 2-3\% of all the hydatid cyst cases reported in the world. Spinal hydatid disease is an even rarer entity. It is endemic in sheep and cattle-raising regions, seen mainly in Mediterranean countries including Turkey and Syria. Pediatric neurosurgeons in non-endemic countries face a challenge when they encounter children with hydatid cysts of the central nervous system, mostly due to lack of awareness and the ensuing diagnostic dilemmas. It is also a significant socioeconomic problem in developing countries, due to improper hygiene and lack of dedicated veterinary practice. The clinical features are largely nonspecific and very according to location and severity of disease. However, with the advent of advances in MR imaging, the diagnostic accuracy of hydatic disease involving the brain and spine has increased. Intact removal of the cyst/s, without causing any spillage, and appropriate antihelminthic therapy is the goal and key to cure and prevention of recurrence. In this manuscript, the current literature on hydatid cyst of the brain and spine is reviewed to better understand the epidemiology, pathophysiology, diagnostic accuracy, and advances in therapeutic options. A heightened clinical suspicion, awareness of MR imaging features, improved surgical strategies, and options for prevention are discussed

    Molecular Profiling in Pancreatic Cancer: Current Role and Its Impact on Primary Surgery

    No full text
    Background: The advent of next-generation sequencing technologies has enabled the identification of molecular subtypes of pancreatic ductal adenocarcinoma (PDAC) with different biological traits and clinically targetable features. Summary: Although current chemotherapy trials are currently exploiting this knowledge, these molecular subtypes have not yet sufficiently caught the attention of surgeons. In fact, integration of these molecular subtypes into the timing of surgery can in theory improve patient outcome. Here, we present the molecular subtypes of PDAC from the surgeon's perspective and a clinically applicable algorithm that integrates the molecular subtyping of PDAC preoperatively into the decision of primary surgery versus neoadjuvant therapy. Furthermore, we point out the potential of ``tailored{''} (in addition to conventional) neoadjuvant treatment for exploiting the molecular subtypes of PDAC. Key Messages: We believe that for surgeons, the preoperative knowledge on the subtype of PDAC can properly guide in deciding between upfront surgery versus neoadjuvant treatment for improving patient outcome

    Sigma metrics in laboratory medicine revisited: We are on the right road with the wrong map

    No full text
    Reliable procedures are needed to quantify the performance of instruments and methods in order to increase the quality in clinical laboratories. The Sigma metrics serves that purpose, and in the present study, the current methods for the calculation of the Sigma metrics are critically evaluated. Although the conventional model based on permissible (or allowable) total error is widely used, it has been shown to be flawed. An alternative method is proposed based on the within-subject biological variation. This model is conceptually similar to the model used in industry to quantify measurement performance, based on the concept of the number of distinct categories and consistent with the Six Sigma methodology. The quality of data produced in clinical laboratories is expected, however, to be higher than the quality of industrial products. It is concluded that this model is consistent with Six Sigma theory, original Sigma metrics equation and with the nature of patients' samples. Therefore, it can be used easily to calculate the performance of measurement methods and instruments used in clinical laboratories.2SI2

    No full text
    Biological variation (BV) data have many applications in laboratory medicine. However, these depend on the availability of relevant and robust BV data fit for purpose. BV data can be obtained through different study designs, both by experimental studies and studies utilizing previously analysed routine results derived from laboratory databases. The different BV applications include using BV data for setting analytical performance specifications, to calculate reference change values, to define the index of individuality and to establish personalized reference intervals. In this review, major achievements in the area of BV from last decade will be presented and discussed. These range from new models and approaches to derive BV data, the delivery of high-quality BV data by the highly powered European Biological Variation Study (EuBIVAS), the Biological Variation Data Critical Appraisal Checklist (BIVAC) and other standards for deriving and reporting BV data, the EFLM Biological Variation Database and new applications of BV data including personalized reference intervals and measurement uncertainty

    No full text
    Polatuzumab vedotin (Pola) with bendamustine and rituximab (BR) is a promising option for patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). We analyzed the data of 71 R/R DLBCL patients who had been treated with Pola-BR in the named patient program from March 2018 to April 2021 from 32 centers in Turkey. All patients received up to six cycles of Pola 1.8 mg/kg, rituximab 375 mg/m(2) on day 1, and bendamustine 90 mg/m(2) on days 1-2 of each cycle. Median age at Pola-BR initiation was 55 (19-84). The overall response rate was 47.9\%, including 32.4\% CR rate when a median of 3 cycles was applied. With a median follow-up of 5 months, the median OS was 5 months. Grade 3-4 neutropenia and thrombocytopenia were the most common hematological toxicities. The real-world data from our cohort showed the Pola-BR is an effective option with a manageable toxicity profile.1JAN133-14010
