Transforaminal Epiduroscopic Basivertebral Nerve Laser Ablation for Chronic Low Back Pain Associated with Modic Changes: A Preliminary Open-Label Study.

Background: Chronic low back pain (CLBP) arising from degenerative disc disease continues to be a challenging clinical and diagnostic problem whether treated with nonsurgical, pain intervention, or motion-preserving stabilization and arthrodesis.

Methods: Fourteen patients with CLBP, greater than 6 months, unresponsive to at least 4 months of conservative care were enrolled. All patients were treated successfully following screening using MRI findings of Modic type I or II changes and positive confirmatory provocative discography to determine the affected levels.

Full Endoscopic Lumbar Discectomy using the Calcification Floating Technique for Symptomatic Partially Calcified Lumbar Herniated Nucleus Pulposus.

Background: Partially calcified lumbar herniated nucleus pulposus (HNP) can cause severe radiating pain and neurologic symptoms requiring surgical treatment. As it is not safe to enforce conventional endoscopic lumbar discectomy using trephine or burr to remove the partially calcified disc, we report a calcification floating technique using a working channel for the treatment of these cases.

Methods: We retrospectively analyzed 31 patients who underwent full endoscopic discectomy using this technique for partially calcified lumbar HNP between April 2009 and June 2013.

Percutaneous Endoscopic Interlaminar Unilateral Ventral Dural Approach for Symptomatic Bilateral L5-S1 Herniated Nucleus Pulposus: Technical Note.

Background:  Percutaneous endoscopic lumbar diskectomy is a good treatment modality for lumbar disk herniation. However, when a patient complains of bilateral lower limb radicular pain with severe disk protrusion at the L5-S1 level, the transforaminal approach is often unable to resolve both lesions owing to anatomical limitations. It is also very difficult to resolve both lesions in an ipsilateral direction using the percutaneous interlaminar approach.

Suprapedicular Circumferential Opening Technique of Percutaneous Endoscopic Transforaminal Lumbar Discectomy for High Grade Inferiorly Migrated Lumbar Disc Herniation.

Purpose: To evaluate the efficacy of suprapedicular circumferential opening technique (SCOT) of percutaneous endoscopic transforaminal lumbar discectomy (PETLD) for high grade inferiorly migrated lumbar disc herniation.

Material And Methods: Eighteen consecutive patients who presented with back and leg pain with a single-level high grade inferiorly migrated lumbar disc herniation were included. High grade inferiorly migrated disc was removed by the SCOT through PETLD approach.

Lumbar chronic subdural hematoma mimicking an intradural extramedullary tumor: A case report.

Background: Chronic spinal subdural hematomas are extremely rare with only 28 cases reported in the literature. Nevertheless, they should be considered among the differential diagnoses for spinal intradural/extramedullary lesions.

Case Report: A 65-year-old male presented with progressive back pain and right S1 radiculopathy.

Analysis of Clinical Results of Three Different Routes of Percutaneous Endoscopic Transforaminal Lumbar Discectomy for Lumbar Herniated Disk.

Objective: Percutaneous endoscopic transforaminal lumbar discectomy (PETLD) can be performed by using foraminal, intervertebral, and suprapedicular routes. The aim of this study was to assess clinical results of three different routes of PETLD.

Methods: One hundred eleven patients who underwent PETLD between January 2016 and October 2016 were included in this study.

Percutaneous Full Endoscopic Treatment of Bertolotti Syndrome: A Report of Three Cases with Technical Note.

 Bertolotti syndrome is characterized by an abnormal enlargement of the transverse process of the most caudal lumbar vertebra. Most of the time it is asymptomatic, but when it is symptomatic it is associated with low back pain, radiating leg pain, or both. There is no consensus regarding management of this pathology.

Mutan: A mixed linkage α-[(1,3)- and (1,6)]-d-glucan from Streptococcus mutans, that induces osteoclast differentiation and promotes alveolar bone loss.

Mutan is an extracellular polysaccharide of Streptococcus mutans (S. mutans) that consists of α-(1,3)-linked glucose residues in main chains and α-(1,6) bonds in side chains. In the present study, mutan was isolated from S.

Lactobacillus plantarum lipoteichoic acid alleviates TNF-α-induced inflammation in the HT-29 intestinal epithelial cell line.

We recently observed that lipoteichoic acid (LTA) isolated from Lactobacillus plantarum inhibited endotoxin-mediated inflammation of the immune cells and septic shock in a mouse model. Here, we examined the inhibitory role of L. plantarum LTA (pLTA) on the inflammatory responses of intestinal epithelial cells (IEC).

Capillary hemangioma of the thoracic spinal cord.

Capillary hemangiomas are common soft tissue tumors on the skin or mucosa of the head and neck in the early childhood, but very rare in the neuraxis. A 47-year-old man presented with one month history of back pain on the lower thoracic area, radiating pain to both legs, and hypesthesia below T7 dermatome. Thoracic spine MRI showed 1×1.

Inhibitory effects of Lactobacillus plantarum lipoteichoic acid (LTA) on Staphylococcus aureus LTA-induced tumor necrosis factor-alpha production.

Staphylococcus aureus is a common etiologic agent for Gram-positive sepsis, and its lipoteichoic acid (LTA) may be important in causing Gram-positive bacterial septic shock. Here, we demonstrate that highly purified LTA (pLTA) isolated from Lactobacillus plantarum inhibited aureus LTA (aLTA)-induced TNF-alpha production in THP- cells. Whereas pLTA scarcely induced TNF-alpha production, aLTA induced excessive TNF-alpha production.

Development of a monitoring vector for Leuconostoc mesenteroides using the green fluorescent protein gene.

The vector pCW5 with plasmid pC7, originally isolated in Lactobacillus paraplantarum C7 derived from kimchi, was constructed using a p32 strong promoter, the pC7 replicon, and green fluorescent protein (GFP) as the reporter. The constructed vector was transformed into E. coli and Leuconostoc mesenteroides, and GFP expression detected using a Western blot analysis.

Construction of a pTOC-T vector using GST-ParE toxin for direct cloning and selection of PCR products.

Using linker insertion mutations, we determined the most stable region of the parE gene which encodes a toxic protein (ParE) that inhibits growth of Escherichia coli. The toxicity of ParE was sustained until a 144 bp linker was inserted into this region. We have developed a 3' T-overhang vector based on these characteristics of the GST-ParE toxin, and named pTOC-T.

New integration vector using a cellulase gene as a screening marker for Lactobacillus.

The new integration vector for Lactobacillus, pJC4, was developed using the extracellular endoglucanase A gene (celA) of Clostridium thermocellum as a screening marker. pJC4 was transformed into four Lactobacillus species, Lb. johnsonii, Lb.
