OBJECTIVES:
This study aimed to compare the effectiveness of ultrasound and acoustic and laser cleaning of curved root canals.
METHODS:
A total of 92 molars with independent root canals with a curvature of 20°-40° were prepared and standardized at 04 25# and stained with gentian violet solution for 72 h. Among them, 52 were randomly divi-ded into four groups for final rinsing (n=13): NI group, PUI group, EDDY group, and PIPS group. Ten samples in each group were cut horizontally along the long axis perpendicular to the root and divided into curved upper, curved, and apical segments. Images were taken with a stereomicroscope and Image J measurements were taken to calculate the depth of rinse penetration. The remaining three samples from each group were split along the long axis of the dentin, photographed by scanning electron microscope to record the dentin tubule exposure and staining layer, and scored for staining layer by double-blind method. SPSS 26.0 software was used to perform statistical analysis and select the best flushing method. An extra 40 samples were randomly divided into four groups for detection of flushing fluid penetration depth (n=10): 10, 20, 30, and 40 s.
RESULTS:
In the upper part, the mean depth of infiltration was not significantly different between the experimental and control groups (P>0.05). The PIPS group had a significantly lower smear layer score than the control group and the EDDY group (P<0.01). In the curved segment, the mean depth of infiltration was significantly greater in the PUI group than in the control group (P<0.05); the tarnish layer score was lower in each experimental group than in the control group. At the top, the mean depth of infiltration was greater in the PUI and PIPS groups than in the control group (P<0.05), and the smear layer score was lower in the PIPS group than in the other groups (P<0.05). After the time was changed, the depth of infiltration of PUI increased only in the apical segment as the flushing time increased.
CONCLUSIONS
The PUI and PIPS methods facilitate the penetration of irrigation solution into the dentin canal in curved root canals, especially in the apical segment. The PIPS technique is effective in removing the smear layer in curved root canals.

3.Optimal Laxatives for Oral Colonoscopy Bowel Preparation: from High-volume to Novel Low-volume Solutions
The Korean Journal of Gastroenterology 2020;75(2):65-73
Optimal bowel preparation is essential for a more accurate, comfortable, and safe colonoscopy. The majority of postcolonoscopy colorectal cancers can be explained by procedural factors, mainly missed polyps or inadequate examination. Therefore the most important goal of optimal bowel preparation is to reduce the incidence of colorectal cancer. Although adequate preparation should be achieved in 85–90% or more of all colonoscopy as a quality indicator, unfortunately 20–30% shows inadequate preparation. Laxatives for oral colonoscopy bowel preparation can be classified into polyethylene glycol (PEG)-electrolyte lavage solution, osmotic laxatives, stimulant laxatives, and divided into high-volume solution (≥3 L) and low-volume solution (<3 L). The updated 2019 European Society of Gastrointestinal Endoscopy (ESGE) guideline is broadly similar to the 2014 American Society for Gastrointestinal Endoscopy (ASGE) recommendations and reaffirms the importance of split-dosing. However, new ESGE guideline, unlike the 2014 ASGE recommendation, suggests the use of high volume or low volume PEG-based regimens as well as that of non-PEG based agents that have been clinically validated for most outpatient scenarios. For effective, safe, and highly adherent bowel preparation, physicians who prescribe and implement colonoscopy should properly know the advantages and limitations, the dosing, and the timing of regimens. Recently many studies have attempted to find the most ideal regimens, and more convenient, effective, and safe regimens have been developed by reducing the dosing volume and improving the taste. The high tolerability and acceptability of the new low-volume regimens suggest us how we should use it to increase the participation of the national colorectal cancer screening program.

Lateral epicondylopathy represents pain in the lateral (radial aspect) of the elbow caused by degeneration in the common extensor tendon. Calcium deposit frequently developes in lateral epicondylopathy, with the prevalence up to 46%. There are considerable debates on its treatment protocols for lateral epicondylopathy so far, likewise, the effective treatment method for calcific lateral epicondylopathy has not been established. We report here a case of chronic intractable calcific lateral epicondylopathy treated with ultrasound-guided barbotage and focused type extracorporeal shock wave therapy (ESWT). To our knowledge, this is the first report of calcific lateral epicondylopathy treated by ultrasound-guided barbotage combined with ESWT.

OBJECTIVES: This study aimed to evaluate the effect of clinical factors on the outcome of arthrocentesis in the treatment of temporomandibular joint (TMJ) internal derangement. MATERIALS AND METHODS: Fifty patients with TMJ internal derangement underwent arthrocentesis using ringer's lactate. The present study evaluated the contribution of the clinical variables of age, time since onset, visual analogue scale (VAS) pain level, and range of motion (ROM) on the outcomes of TMJ arthrocentesis: age (≤25 years, >25 and ≤40 years, >40 and ≤60 years), VAS pain level (≤5, >5 and ≤7, >7 and ≤10), and ROM ( < 25 and ≥25 mm). Odds ratios (ORs) were used to describe the proportional benefit of each variable the on successful outcome of arthrocentesis. For the OR to be clinically relevant or even clinically noticeable, we assumed that the OR would need to be larger than 2. RESULTS: Mean preoperative pain score was 6.49±1.560 and at 6 months postoperative was 0.46±1.147 with an average decrease of pain score 6 (P < 0.001). The mean preoperactive maximum mouth opening was 26.14±4.969 mm and mean maximum mouth opening at 6-month inerval was 38.92±3.392 mm. The mean increase in the mouth opening was a mean difference of 12.78 mm (P < 0.001). Logistic regression showed that the maximum benefit occurred in patients aged < 25 years (OR, 12.01; P=0.012), a VAS pain level of >7 (OR, 11.25; P=0.039), and a maximum vertical opening of < 25 mm (OR, 7.70; P=0.038). CONCLUSION: Lavage of the superior joint space with ringer's lactate resulted in significant reduction in pain and improvement in mouth opening. Patients with a greater inflammatory component and younger patients benefitted more from arthrocentesis. Evaluation of these clinical variables helped in predictive modelling, which may provide clinicians with the opportunity to identify “at-benefit” patients early and initiate specific treatment.

The principles of open fracture management are to manage the overall injury and specifically prevent primary contamination becoming frank infection. The surgical management of these complex injuries includes debridement & lavage of the open wound with combined bony and soft tissue reconstruction. Good results depend on early high quality definitive surgery usually with early stable internal fixation and associated soft tissue repair. While all elements of the surgical principles are very important and depend on each other for overall success the most critical element appears to be achieving very early healthy soft tissue cover. As the injuries become more complex this involves progressively more complex soft tissue reconstruction and may even requiring urgent free tissue transfer requiring close co-operative care between orthopaedic and plastic surgeons. Data suggests that the best results are obtained when the whole surgical reconstruction is completed within 48-72 h.

PURPOSE: To report a case of toxic optic neuropathy caused by chlorfenapyr ingestion accompanied by central nervous system involvement. CASE SUMMARY: A 44-year-old female visited our clinic complaining of reduced visual acuity in both eyes for 7 days. She had ingested a mouthful of chlorfenapyr for a suicide attempt 2 weeks prior to the visit. Gastric lavage was performed immediately after ingestion at the other hospital. Her best-corrected visual acuity was finger count 30 cm in the right eye and hand motion in the left eye. Both pupils were dilated by 5.0 mm and the response to light was sluggish in both eyes. A relative afferent pupillary defect was detected in her left eye. Funduscopy revealed optic disc swelling in both eyes. Magnetic resonance imaging of the brain showed a symmetric hyper-intense signal in the white matter tract including the internal capsule, corpus callosum, middle cerebellar peduncle, and brainstem. The patient was diagnosed with toxic optic neuropathy induced by chlorfenapyr ingestion, and underwent high-dose intravenous corticosteroid pulse therapy. Three days later, the best-corrected visual acuity was no light perception in both eyes. Three months later, optic atrophy was observed in both eyes. Optical coherence tomography revealed a reduction in the thicknesses of the retinal nerve fiber layer and ganglion cell and inner plexiform layer in the macular area. CONCLUSIONS: Ingestion of even a small amount of chlorfenapyr can cause severe optic nerve damage through the latent period, despite prompt lavage and high-dose steroid treatment.

ObjectiveTo evaluate the effectiveness and safety of low-concentration hydrogen peroxide solution (HPS) for continuous bladder irrigation after transurethral resection of the prostate (TURP).
METHODSWe retrospectively analyzed the clinical data about 148 cases of benign prostatic hyperplasia (BPH) treated by TURP from January 2013 to January 2016. Seventy-six of the patients received postoperative continuous bladder irrigation with 0.15% HPS (group A) and the other 72 with normal saline (group B). We compared the two groups of patients in their postoperative hemoglobin (Hb) levels, duration of bladder irrigation, frequency of catheter blockage, time of catheterization, and length of hospital stay.
RESULTSThere were no statistically significant differences between the two groups of patients preoperatively in the prostate volume, International Prostate Symptoms Score, maximum urinary flow rate, postvoid residual urine, or levels of serum PSA and Hb (P > 0.05). At 48 hours after operation, a significantly less reduction was observed in the Hb level in group A than in group B ([3.38 ± 2.56] vs [7.29 ± 6.58] g/L, P < 0.01). The patients of group A, in comparison with those of group B, also showed remarkably shorter duration of postoperative bladder irrigation ([32.57 ± 5.99] vs [46.10 ± 8.79] h, P < 0.01), lower rate of catheter blockage (3.3% vs 11.8%, P < 0.01), shorter time of catheterization ([3.74 ± 0.79] vs [4.79 ± 0.93] d, P < 0.01), and fewer days of postoperative hospital stay ([4.22 ± 0.81] vs [4.67 ± 0.88] d, P < 0.01).
CONCLUSIONSLow-concentration HPS for continuous bladder irrigation after TURP can reduce blood loss, catheter blockage, bladder irrigation duration, catheterization time, and hospital stay, and therefore deserves a wide clinical application.

BACKGROUND/AIMS: Syndecan-2 (SDC2) methylation was previously reported as a sensitive serologic biomarker for the early detection of colorectal cancer (CRC). The purpose of this study was to investigate whether SDC2 methylation is detectable in precancerous lesions and to determine the feasibility of using SDC2 methylation for the detection of CRC and precancerous lesions in bowel lavage fluid (BLF). METHODS: A total of 190 BLF samples were collected from the rectum at the beginning of colonoscopy from patients with colorectal neoplasm and healthy normal individuals. Fourteen polypectomy specimens were obtained during colonoscopy. A bisulfite pyrosequencing assay and quantitative methylation-specific polymerase chain reaction were conducted to measure SDC2 methylation in tissues and BLF DNA. RESULTS: SDC2 methylation was positive in 100% of villous adenoma (VA) and high-grade dysplasia, and hyperplastic polyp samples; 88.9% of tubular adenoma samples; and 0% of normal mucosa samples. In the BLF DNA test forSDC2 methylation, the sensitivity for detecting CRC and VA was 80.0% and 64.7%, respectively, at a specificity of 88.9%. The BLF of patients with multiple tubular adenomas, single tubular adenoma and hyperplastic polyps showed 62.8%, 26.7% and 28.6% rates of methylation-positive SDC2, respectively. CONCLUSIONS: Our results demonstrated that SDC2 methylation was a frequent event in precancerous lesions and showed high potential in BLF for detecting patients with colorectal neoplasm.
