Posterior Extensive Circumferential Decompressive Reconstructive Technique in surgical treatment of Upper Thoracic Spine Compressive Lesions.

World Neurosurg 2018 Dec 3. Epub 2018 Dec 3.

Department of Orthopedic Surgery and Traumatology and Minia University Hospital, Mohammed Badway str., 61111, El-Minia, Egypt; Minia University Spine Unit (MUSU), Faculty of Medicine, Minia University. Minia University Hospital, Mohammed Badway str., 61111, El-Minia, Egypt. Electronic address:

Background Data: Complexity in ventral surgical exposure, presence of scapula and large para-scapular musculature during posterior surgery are the main obstacles in operative treatment of Upper Thoracic Spine Compressive Lesions (UTSCL) like trauma, tuberculosis and neoplasm. Recently, the advantages of combined ventro-dorsal surgery could be successfully gained using 1-stage posterior salvage technique with enough accessibility to all three spinal columns.

Purpose: Retrospective evaluation of 35 patients with UTSCL treated by Posterior Extensive Circumferential Decompressive Reconstructive (PECDR) procedure. Read More

Special features of monolayer characteristics of N-alkanoyl substituted threonine amphiphiles.

Phys Chem Chem Phys 2018 Dec 6. Epub 2018 Dec 6.

Max Planck Institute of Colloids and Interfaces, D-14424 Potsdam/Golm, Germany.

The monolayers of N-alkanoyl substituted threonine amphiphiles, similar to those of other N-alkanoyl-substituted amino acid amphiphiles, point to substantial differences in the main characteristics compared to usual amphiphilic monolayers. π-A measurements of the enantiomeric and racemic forms of N-alkanoyl-substituted threonine monolayers with C16 and C18 chain lengths reveal that, independent of the alkyl chain length, all compression curves are located above the corresponding decompression curves. A theoretical model developed for the kinetics of two-dimensional condensation of Langmuir monolayers can describe this behavior concluding the attachment of monomers to large aggregates. Read More

Unilateral Biportal Endoscopic Spinal Surgery Using a 30° Arthroscope for L5-S1 Foraminal Decompression.

Clin Orthop Surg 2018 Dec 21;10(4):508-512. Epub 2018 Nov 21.

Department of Spine Surgery, Barun Hospital, Jinju, Korea.

Foraminal decompression using a minimally invasive technique to preserve facet joint stability and function without fusion reportedly improves the radicular symptoms in approximately 80% of patients and is considered one of the good surgical treatment choices for lumbar foraminal or extraforaminal stenosis. However, proper decompression was not possible because of the inability to access the foramen at the L5-S1 level due to prominence of the iliac crest. To overcome this challenge, endoscopy-based minimally invasive spine surgery has recently gained attention. Read More

Ring graft technique for microvascular decompression.

Neurol India 2018 Nov-Dec;66(6):1687-1691

Department of Neurosurgery, GIPMER and Maulana Azad Medical College, New Delhi, India.

Introduction: Various nerve compression syndromes, such as trigeminal neuralgia (TN), glossopharyngeal neuralgia (GN), and hemifacial spasm (HFS), are caused by compression of the concerned nerve by the adjacent vessel. Patients who do not respond to medical management are usually treated by "microvascular decompression (MVD) of the nerve." Teflon patch graft is the most commonly used material for MVD. Read More

A Significant Proportion of Small Bowel Obstructions Require >48 Hours to Resolve After Gastrografin.

J Surg Res 2019 Jan 18;233:408-412. Epub 2018 Sep 18.

Division of Surgery, Trauma and Surgical Critical Care, Dewitt-Daughtry Family Department of Surgery, University of Miami Miller School of Medicine and Ryder Trauma Center, Miami, Florida.

Background: Gastrografin (GG)-based nonoperative approach is both diagnostic and therapeutic for partial small bowel obstruction (SBO). Absence of X-ray evidence of GG in the colon after 8 h is predictive of the need for operation, and a recent trial used 48 h to prompt operation. We hypothesize that a significant number of patients receiving the GG challenge require >48 h before an effect is seen. Read More

Yoshiharu Suzuki

J Chem Phys 2018 Nov;149(20):204501

Research Center for Advanced Measurement and Characterization, National Institute for Materials Science (NIMS), Namiki 1-1, Tsukuba, Ibaraki 305-0044, Japan.

To solve a mystery of low-temperature liquid water, a liquid-liquid critical point (LLCP) hypothesis that the two kinds of waters, low-density and high-density liquids (LDL and HDL), and a critical point relating to the two waters exist is thought to be the most realistic idea. However, there is no conclusive evidence showing the existence of LLCP. I measured the polyamorphic volume changes of the glassy dilute polyol (ethylene glycol, glycerol, -erythritol, xylitol, and D-sorbitol) aqueous solutions during the compression and decompression processes and estimated the location of LLCP for the polyol aqueous solution by a new analysis of the concentration dependence of polyamorphic transition.

Diving Hyperb Med 2018 Dec;48(4):252-258

Washington DC, USA.

Introduction: Whilst the US Navy has been very systematic about validating Navy dive computer algorithms, there has been little documented or published evidence of rigorous testing of the algorithms in commercial off-the-shelf dive computers. This paper reports the evaluation of four algorithms used in these - Bühlmann ZHL-16C; VPM-B; Suunto-RGBM; EMC-20H - by comparison with US Navy experimental dives with known decompression sickness outcomes.

Methods: Three specific tests were developed to test the algorithms' ability to mitigate decompression sickness: Total decompression time; no stop times and first stop depth. Read More

UAB Faculty Office Tower #960, 510 20th Street South, Birmingham, AL 35233, USA.

Traumatic lumbosacral dislocation is a rare, high-energy mechanism injury characterized by displacement of the fifth lumbar vertebra in relation to the sacrum. Due to the violent trauma typically associated with this lesion, there are often severe, coexisting injuries. High-quality radiographic studies, in addition to appropriate utilization of CT scan and MRI, are essential for proper evaluation and diagnosis. Read More

Department of Anesthesiology and Pain Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea.

Background: When conventional interventional procedures fail, percutaneous epidural adhesiolysis (PEA), which has moderate evidence for successful treatment of lumbar spinal stenosis (LSS), has been recommended over surgical treatments. In a previous study, we demonstrated the efficacy of a newly developed inflatable balloon catheter for overcoming the access limitations of pre-existing catheters for patients with severe stenosis or adhesions.

Objectives: This study compared the treatment response of combined PEA with balloon decompression and PEA only in patients with central LSS over 6 months of follow-up. Read More

Predictors of Unplanned Returns to the Operating Room within 30 Days in Neurosurgery: Insights from a National Surgical Registry.

World Neurosurg 2018 Nov 27. Epub 2018 Nov 27.

Mayo Clinic Neuro-Informatics Laboratory, Mayo Clinic College of Medicine and Science, Rochester, MN. Electronic address:

Background: In the modern, increasingly pay-for-performance era, unplanned ROR is gaining attention as a surgical quality metric. However, large-scale data on the appropriateness and utility of this measure in neurosurgery are scarce.

Objective: To provide a comprehensive description of all unplanned returns to the operating room (RORs) after neurosurgical procedures in a national surgical registry and identify factors associated with ROR. Read More

Recurrence of nonsyndromic odontogenic keratocyst after marsupialization and delayed enucleation vs. enucleation alone: a systematic review and meta-analysis.

Oral Maxillofac Surg 2018 Nov 29. Epub 2018 Nov 29.

Department of Oral and Maxillofacial Surgery, Traumatology and Prosthesis, Faculty of Dentistry of the University of São Paulo, Av Prof. Lineu Prestes 2227 Butantã, São Paulo, 05508-000, Brazil.

Purpose: This study was conducted in order to determine whether marsupialization before definitive enucleation of nonsyndromic odontogenic keratocysts (OKCs) is capable of decreasing the recurrence rate more effectively than just enucleation.

Methods: We searched MEDLINE, Web of Science, Scopus, and Cochrane Library, until August 5th of 2017 for original studies reporting on the treatment of OKCs with and without previous marsupialization and the related recurrence rate. All records and data were independently assessed, meta-analysis was performed, and the odds ratio of recurrence was the effect measure; P value for the summary effect of < 0. Read More
