Article Multi-Level Cervical Disc Degeneration and Vertigo(Georg Thieme verlag Kg, 2022) Ercan, Serdar; Baloglu, MuratObjective While complaints of pain, loss of strength, and numbness radiating to the neck and arm are common in patients due to cervical disc degeneration, vertigo is a rare symptom. The articles previously published on the subject focus on single-level disk degeneration and its correlation with vertigo. However, in the case of multilevel cervical discopathy, its effect on the severity of vertigo and its response to surgical treatment has not been clarified. Therefore, the objective of the present study is to shed light on the topic. Methods Patients with vertigo complaints in whom all known etiological causes of vertigo had been excluded, but with cervical disc degeneration, were included in the study. The scores on the Visual Analog Scale (VAS) and Cervical Vertigo Evaluation Scale (CVES) were analyzed in terms of numbers of discopathy, spine levels, and differences regarding the preoperative and postoperative status. Results A total of 24 patients (14 with single-level and 10 with multi-level disc degeneration) underwent anterior cervical discectomy. The preoperative CVES score was significantly decreased after surgery. Multi-level disc degeneration causes fewer vertigo symptoms than the single-level kind. No significant correlation between the severity of pain and vertigo was observed. Conclusion Multi-level disc degeneration causes fewer vertigo symptoms. These symptoms decreased after anterior cervical discectomy in cases of single-level disk herniation at upper segments. The surgical intervention could be a favorable choice of treatment. However, the mechanism and treatment approach to cervical vertigo is still a controversial issue.Article Citation - WoS: 1Citation - Scopus: 2A Pilot Study of a Novel Fixation Technique for Fixation of Comminuted Patellar Fractures: Arthroscopic-Controlled Reduction and Circular External Fixation(Georg Thieme verlag Kg, 2020) Neyisci, Cagri; Erdem, Yusuf; Kilic, Erden; Arsenishvili, Arsen; Kurklu, MustafaPatella fractures represent for 0.5 to 1.5% of all bony injuries in adults. Open reduction and the modified tension-band technique is the most common surgical technique used for patellar fractures. The purpose of this study is to present the outcomes of 26 comminuted patellar fractures treated with circular external fixator (CEF) under arthroscopic control and discuss its potential advantages over conventional surgical methods. This retrospective study included 26 patients who had closed comminuted patellar fractures and treated by CEF under arthroscopic control between January 2002 and March 2016. All patients treated with this technique were involved to the study as a consecutive series. Patients with noncomminuted transverse fractures were excluded, because they were treated with a different technique. Of the 26 patients 22 were male, 4 were female with the mean age of 33.5 years (range, 16-56 years). Patients were followed for 20 to 28 months (mean, 22 months). The mean time to union and the duration of fixation with the CEF ring was 12 weeks (range, 6-15 weeks). The mean Lysholm's score was 45 (range, 35-58) at the 10th postoperative day, which increased to 51 (range, 40-68) at the end of the first postoperative month and increased to 95 (range, 90-100) 1 month after CEF ring removal. Minor pin tract infection by pin-skin irritation was observed in nine patients. In one patient, refracture occurred due to a fall 19 days after CEF removal. CEF appears to be a safe and effective treatment for comminuted patellar fractures with a high union rate and minimal complications. It is safe and effective, as it allows short hospital stay and avoids a second surgery for removal of the instrument. Early rehabilitation with full weight-bearing promotes rapid recovery and quick return to work. Patients do not have a large unaesthetic scar on the anterior of the knee.Article Citation - WoS: 19Citation - Scopus: 19Poly(3,4-Alkylenedioxyselenophene)s: Past, Present, and Future(Georg Thieme verlag Kg, 2015) Cihaner, AtillaBecause of their optical and electronic properties, polythiophenes and their derivatives, especially poly(3,4-alkylenedioxythiophene)s, are among the most promising materials in the field of electrochromic polymers. The properties of these polymers can be tuned by replacing the sulfur atom of the thiophene moiety with a selenium atom, because selenium has a lower electronegativity, a higher metallic character, a larger atomic size, and greater polarizability than sulfur. This approach has opened the door to a new and vibrant class of conjugated polymers. Today 3,4-alkylenedioxyselenophenes are thought as powerful competitors to 3,4-alkylenedioxythiophenes. Here, an overview is presented of poly(3,4-alkylenedioxyselenophene)s, as one of the most attractive groups of conjugated polymers. The design, synthesis, and applications of poly(3,4-alkylenedioxyselenophene)s and their derivatives are discussed in detail and compared with the corresponding features of their thiophene analogues. The electrochemical and electrochromic properties and band gaps of poly(3,4-alkylenedioxyselenophene) s are also discussed in relation to their chemical structures. 1 Introduction 2 Polyselenophenes 3 Poly(3,4-ethylenedioxyselenophene)s 4 Poly(3,4-propylenedioxyselenophene)s 5 ConclusionsReview Citation - WoS: 16Citation - Scopus: 20Assessing the Coverage of E-Health Services in Sub-Saharan Africa a Systematic Review and Analysis(Georg Thieme verlag Kg, 2017) Adeloye, Davies; Adigun, Taiwo; Misra, Sanjay; Omoregbe, NicholasBackground: E-Health has attracted growing interests globally. The relative lack of facilities, skills, funds and information on existing e-Health initiatives has affected progress on e-Health in Africa. Objectives: To review publicly available literature on e-Health in sub-Saharan Africa (sSA) towards providing information on existing and ongoing e-Health initiatives in the region. Methods: Searches of relevant literature were conducted on Medline, EMBASE and Global Health, with search dates set from 1990 to 2016. We included studies on e-Health initiatives (prototypes, designs, or completed projects) targeting population groups in sSA. Results: Our search returned 2322 hits, with 26 studies retained. Included studies were conducted in 14 countries across the four sub-regions in sSA (Central, East, South and West) and spreading over a 12-year period, 2002-2014. Six types of e-Health interventions were reported, with 17 studies (65%) based on telemedicine, followed by mHealth with 5 studies (19%). Other e-Health types include expert system, electronic medical records, e-mails, and online health module. Specific medical specialties covered include dermatology (19%), pathology (12%) and radiology (8%). Successes were 'widely reported' (representing 50% overall acceptance or positive feedbacks in a study) in 10 studies (38%). The prominent challenges reported were technical problems, poor inter net and connectivity, participants' selection biases, contextual issues, and lack of funds. Conclusion: E-Health is evolving in sSA, but with poorly published evidence. While we call for more quality research in the region, it is also important that population-wide policies and on-going e-Health initiatives are contextually feasible, acceptable, and sustainable.
