SELD

Conventional organic light-emitting devices without an encapsulation layer are susceptible to degradation when exposed to air, so realization of air-stable intrinsically-stretchable display is a great challenge because the protection of the devices against penetration of moisture and oxygen is even more difficult under stretching. An air-stable intrinsically-stretchable display that is composed of an intrinsically-stretchable electroluminescent device (SELD) integrated with a stretchable color-conversion layer (SCCL) that contains perovskite nanocrystals (PeNCs) is proposed...

Objective: Nowadays, trans-sacral epiduroscopic laser decompression (SELD) using slender epiduroscopy and laser is one of the preferred options for minimally invasive treatment in lumbar disc diseases. However, SELD is still in the initial stages of the global field of spine surgery, and the clinical outcomes in patients with lumbar disc herniation are not established yet. Therefore, the authors investigated patients undergoing SELD to report the clinical results. Methods: Between November 2015 and November 2018, a total of 82 patients who underwent single-level SELD for lumbar disc herniation with a minimum follow-up of 6...

The selenocysteine (Sec) incorporation is a co-translational event taking place at an in-frame UGA-codon and dependent on an organized molecular machinery. Selenium delivery requires mainly two enzymes, the selenocysteine lyase (CsdB) is essential for Sec recycling and conversion to selenide, further used by the selenophosphate synthetase (SelD), responsible for the conversion of selenide in selenophosphate. Therefore, understanding the catalytic mechanism involved in selenium compounds delivery, such as the interaction between SelD and CsdB (EcCsdB...

Objective: In this study, we report a patient who developed lumbar epidural hematoma after trans-sacral epiduroscopic laser decompression (SELD). Background: SELD is a nonoperative minimally invasive spinal procedure, in which a herniated lumbar disk can be ablated by laser. Because of the rich epidural venous plexus, the procedure might have a risk of epidural hematoma. Materials and methods: A 57-year-old woman underwent the SELD procedure for the treatment of lower back and right buttock pain due to disk protrusion at L5-S1...

PURPOSE: To determine the degree of correlation of radiographic measurements, degree of correlation of intraoperative pathology, and difference in outcomes between sides of patients requiring staged bilateral hip arthroscopy. METHODS: Two high-volume hip preservation centers retrospectively reviewed hip preservation databases for staged bilateral hip arthroscopies conducted between 2008 and 2015. Patients were separated into those who presented with bilateral hip pain and those that presented with unilateral pain and developed contralateral pain >2 years later...

Percutaneous epidural neuroplasty (PEN) is an effective and safe procedure for herniated lumbar disc (HLD). Although PEN has an advantage of adhesiolysis, this procedure cannot decompress the protruded disc. Recently, trans-sacral epiduroscopic laser decompression (SELD) for HLD has been introduced as a promising alternative methodology. This study evaluated the clinical efficacy and safety of SELD compared to PEN, as well as the change in protruded disc volume after SELD through pre- and postoperative magnetic resonance imaging (MRI), in patients with HLD...

OBJECTIVE: Evaluate interobserver and intraobserver reliability of hip arthroscopic classifications for labral tears. DESIGN: Retrospective diagnostic study of nonconsecutive patients. SETTING: Institutional study. PATIENTS: From a database of 278 hip arthroscopy videos for treatment of femoroacetabular impingement, 70 videos were chosen by simple random sampling. Exclusion criteria included presence of radiological arthrosis (Tonnis > 2), previous hip surgery, inadequate lesion palpation, poor image quality, and refusal to participate in the study...

BACKGROUND: Revision hip arthroscopy is increasingly common and often addresses acetabular labrum pathology. There is a lack of consensus on indications or outcomes of revision labral repair versus reconstruction. PURPOSE: To report clinical outcomes of labral reconstruction during revision hip arthroscopy at minimum 2-year follow-up as compared with pair-matched labral repair during revision hip arthroscopy (control group) and to suggest a decision-making algorithm for labral treatment in revision hip arthroscopy...

PURPOSE: This study sought to investigate the association between tomographic femoroacetabular impingement (FAI) angles and histologically evaluated labral tears. The authors hypothesized that cadavers presenting with cam and pincer morphologies would present a higher prevalence of acetabular labral tears. METHODS: Twenty fresh cadavers were submitted to computed tomography. Standard FAI angles were measured, including the alpha angle, femoral version, acetabular version, Tonnis angle and center-edge angle...

OBJECTIVES: The aim of this study was to contribute to the knowledge of pre-Hispanic Andean mitochondrial diversity by analyzing an individual from the archaeological site Pukara de La Cueva (North-western Argentina). The date of the discovery context (540 ± 60 BP) corresponds to the Regional Developments II period. METHODS: Two separate DNA extractions were performed from dentin powder of one tooth. HVR I was amplified by PCR from each extract in three overlapping fragments and the haplotype was determined by consensus among all obtained sequences...

RATIONALE: CRPS after a lumbar surgery has symptoms that are similar to PSSS. However, standard criteria for distinguishing CRPS from PSSS do not exist. We present a case report of a 31-year-old female with CRPS symptoms after lumbar spinal surgery treated by performing SELD. PATIENT CONCERNS: This patient was referred to our pain clinic for left ankle pain. She received a lumbar discectomy for a herniated lumbar disc (L5/S1) but the pain was aggravated after surgery...

OBJECTIVES: The main aim of this work was to contribute to the knowledge of pre-Hispanic genetic variation and population structure among the South-central Andes Area by studying individuals from Quebrada de Humahuaca, North-western (NW) Argentina. MATERIALS AND METHODS: We analyzed 15 autosomal STRs in 19 individuals from several archaeological sites in Quebrada de Humahuaca, belonging to the Regional Developments Period (900-1430 AD). Compiling autosomal, mitochondrial, and Y-chromosome data, we evaluated population structure and differentiation among eight South-central Andean groups from the current territories of NW Argentina and Peru...

CONTEXT/OBJECTIVE: Trans-sacral epiduroscopic laser decompression (SELD) is an alternative to microscopic open lumbar discectomy (OLD). SELD and OLD for L5-S1 lumbar disc herniation (LDH) have not been compared. We compared clinical results, including pain control, between SELD and OLD. DESIGN: Retrospective analysis. SETTING: Korean hospital. PARTICIPANTS: Eighty patients treated with SELD (n = 40) or microscopic OLD (n = 40) for L5-S1 LDH...

Background: Hip arthroscopic surgery is intended to treat multiple abnormalities in an effort to delay the progression to osteoarthritis, especially in young patients. However, the length of time in which patients experience joint pain before seeking a specialist for a diagnosis can delay hip preservation surgery and influence clinical outcomes. Purpose: To investigate the relationship between age at symptom onset and findings during hip arthroscopic surgery as well as outcomes after 2 years of clinical follow-up...

BACKGROUND: Trans-sacral epiduroscopic lumbar decompression (SELD) is an emerging procedure for the treatment of lumbar disc herniation (LDH), with favorable outcomes having been reported. However, the complications associated with SELD have not been comprehensively evaluated to date. Therefore, the aim of our study was to describe the incidence rate, types, and characteristics of complications following SELD and management outcomes. METHODS: Retrospective analysis of the surgical and clinical outcomes for 127 patients (average age, 42...

BACKGROUND: Arthroscopic labral debridement in the hip can be an effective treatment for labral tears but has demonstrated inferior outcomes compared with labral repair. Thus, the role for labral debridement has become unclear. Hypothesis/Purpose: The purpose was to evaluate the outcomes of a selective debridement with labral preservation (SDLP) group with a minimum 5-year follow-up. It was hypothesized that, with narrow indications, SDLP would produce statistically improved patient-reported outcome (PRO) scores, comparable with those of a matched-pair labral repair control group...

Clostridium difficile is a significant concern as a nosocomial pathogen, and genetic tools are important when analyzing the physiology of such organisms so that the underlying physiology/pathogenesis of the organisms can be studied. Here, we used TargeTron to investigate the role of selenoproteins in C. difficile Stickland metabolism and found that a TargeTron insertion into selD, encoding the selenophosphate synthetase that is essential for the specific incorporation of selenium into selenoproteins, results in a significant growth defect and a global loss of selenium incorporation...

RATIONALE: Trans-sacral epiduroscopic laser decompression (SELD) is reported to have strong positive short-term effects in controlling lower back pain (LBP) or radicular leg pain following herniated lumbar disc (HLD). However, little is known about the possible complications following SELD. PATIENT CONCERNS: A 36-year-old man received SELD with YAG laser for controlling LBP and radicular pain due to HLD on L5-S1. However, after SELD, voiding and defecation difficulties and sensory deficits on the S3-5 dermatome were presented...

BACKGROUND: Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is an example of an abnormality requiring osseous correction with a technically challenging access point. PURPOSE: To report on the patterns of clinical presentation and intra-articular derangements, radiological associations, and minimum 2-year outcomes after hip arthroscopic surgery in patients with a lateral center edge angle (LCEA) >40° and profunda acetabulae in comparison with matched controls with normal acetabular coverage...
