PURPOSE: To analyze the maxillary sinus anatomy over edentulous ridges in the bilateral posterior maxillary area in Taiwanese patients using cone-beam computed tomography (CBCT). METHODS: In total, 101 anatomical sites from 61 patients, including 32 premolar and 69 molar regions, were analyzed using CBCT. Measurements were made of the width and height of edentulous ridges, the thickness of the lateral wall of the maxillary sinus, and the presence of a sinus septum and the posterior superior alveolar artery (PSAA). A statistical analysis of the measurements was performed, and correlations among the measurements were assessed. RESULTS: The average ridge width was 10.26±3.16 mm, with a significantly greater ridge width in the second molar region than in the premolar region. The mean residual ridge height was 8.55±4.09 mm, and ridge height showed an opposite trend from ridge width for the premolar and molar regions. A sinus septum was present at 5.9% of the sites, and the PSAA was observed in 24.5%. The average thickness of the lateral wall of the maxillary sinus was 2.08±0.94 mm, with no significant difference between the tooth position and lateral wall thickness. CONCLUSIONS: This study presents the anatomical features of the maxillary sinus, which should be considered in sinus lift procedures for implant placement, in the Taiwanese population. The use of CBCT is recommended to avoid intraoperative complications.

OBJECTIVETo evaluate the ability of lactic acid bacteria (LAB) strains isolated from fermented mustard to lower the cholesterol in vitro.
METHODSThe ability of 50 LAB strains isolated from fermented mustard on lowering cholesterol in vitro was determined by modified o-phtshalaldehyde method. The LAB isolates were analyzed for their resistance to acid and bile salt. Strains with lowering cholesterol activity, were determined adherence to Caco-2 cells.
RESULTSStrain B0007, B0006 and B0022 assimilated more cholesterol than BCRC10474 and BCRC 17010. The isolated strains showed tolerance to pH 3.0 for 3 h despite variations in the degree of viability and bile-tolerant strains, with more than 10(8) CFU/mL after incubation for 24 h at 1% oxigall in MRS. In addition, strain B0007 and B0022 identified as Lactobacillus plantarum with 16S rDNA sequences were able to adhere to the Caco-2 cell lines.
CONCLUSIONSThese strains B0007 and B0022 may be potential functional sources for cholesterol-lowering activities as well as adhering to Caco-2 cell lines.

A 28-year-old female with a 1-year history of ketamine abuse developed ketamine-associated urinary symptoms that were refractory to conservative treatment after the complete cessation of ketamine use. Smooth voiding with increased bladder capacity and minimal postvoid residual urine volume were achieved by performing an augmentation enterocystoplasty. An uneventful pregnancy with the vaginal delivery of a healthy baby occurred postoperatively.

Inflammatory bowel diseases are idiopathic inflammatory diseases of two main types, Crohn's disease and ulcerative colitis. Crohn's disease can affect the entire gastrointestinal tract, and the distal ileum is involved in up to 70% of patients. Moreover, Crohn's disease in one-quarter to one-third of patients involves isolation of the small bowel. Due to the nonspecific symptoms and anatomical location of the disease, small bowel Crohn's disease is a phenotype that is particularly difficult to manage. Since the introduction of capsule endoscopy in 2000 and balloon-assisted enteroscopy in the 21st century, it is now possible to directly inspect for small bowel Crohn's disease. However, the new modalities still have limitations, such as capsule retention and invasiveness of balloon-assisted enteroscopy. The diagnostic yields of both capsule endoscopy and balloon-assisted enteroscopy are high for patients with suspected small bowel Crohn's disease. Therefore, earlier use of capsule endoscopy or balloon-assisted enteroscopy can help with the diagnosis and earlier treatment of these patients to avert possible disastrous outcomes.

Although agomelatine may be associated with an increased risk of hepatotoxicity, the incidence rate of acute hepatitis seemed divergent between clinical trials and daily practice. Whether aging or gender is a risk factor in developing hepatotoxicity due to agomelatine is not clear. We present 3 older female cases with acute hepatitis occurring due to highly probable idiosyncratic drug-induced liver injury caused by agomelatine. From these cases, regular surveillance on liver function in the older women taking antidepressants would be of benefits.

Alzheimer’s disease (AD) is a neurodegenerative disease with progressive memory loss and the cognitive decline. AD is mainly caused by abnormal accumulation of misfolded amyloid β (Aβ), which leads to neurodegeneration via a number of possible mechanisms such as down-regulation of brain-derived neurotrophic factor-tropomyosin-related kinase B (BDNF-TRKB) signaling pathway. 7 ,8-Dihydroxyflavone (7,8-DHF), a TRKB agonist, has demonstrated potential to enhance BDNF-TRKB pathway in various neurodegenerative diseases. T o expand the capacity of flavones as TRKB agonists, two natural flavones quercetin and apigenin, were evaluated. With tryptophan fluorescence quenching assay, we illustrated the direct interaction between quercetin/ apigenin and TRKB extracellular domain. Employing Aβ folding reporter SH-SY5Y cells, we showed that quercetin and apigenin reduced Aβ-aggregation, oxidative stress, caspase-1 and acetylcholinesterase activities, as well as improved the neurite outgrowth. Treatments with quercetin and apigenin increased TRKB Tyr516 and Tyr817 and downstream cAMP-response-element binding protein (CREB) Ser133 to activate transcription of BDNF and BCL2 apoptosis regulator (BCL2), as well as reduced the expression of pro-apoptotic BCL2 associated X protein (BAX). Knockdown of TRKB counteracted the improvement of neurite outgrowth by quercetin and apigenin. Our results demonstrate that quercetin and apigenin are to work likely as a direct agonist on TRKB for their neuroprotective action, strengthening the therapeutic potential of quercetin and apigenin in treating AD.

BACKGROUND/AIMS: Only moderate to severe Crohn's Disease (CD) patients without a satisfactory conventional therapy effect are eligible to get reimbursement from the National Health Insurance of Taiwan for using adalimumab. These are more stringent criteria than in many Western countries and Japan and Korea. We aim to explore the efficacy of using adalimumab in CD patients under such stringent criteria. METHODS: A retrospective analysis was conducted in nine medical centers in Taiwan and we collected the results of CD patients receiving adalimumab from Sep 2009 to Mar 2014. The clinical characteristics, response measured by CDAI (Crohn's Disease Activity Index), adverse events and survival status were recorded and analyzed. CR-70, CR-100, and CR-150 were defined as attaining a CDAI decrease of 70, 100 or 150 points compared with baseline. RESULTS: A total of 103 CD patient records were used in this study. Sixty percent of these patients received combination therapy of adalimumab together with immunomodulators. CR-70 was 68.7%, 74.5% and 88.4% after week 4, 8 and 12 of treatment, respectively. The steroid-free rate, complications and survival were 47.6%, 9.7% and 99% of patients, respectively. In considering the mucosal healing, only 25% patients achieve mucosal healing after treatment for 6 to12 months. Surgery was still needed in 16.5% of patients. Combination treatment of adalimumab with immunomodulators further decreased the level of CDAI at week 8 when compared with the monotherapy. CONCLUSIONS: Even under the stringent criteria for using adalimumab, the response rate was comparable to those without stringent criteria.

BACKGROUND AND OBJECTIVES: The aim of this study was to identify clinical, lesional, and procedural predictors for adverse outcomes of coronary angioplasty and stenting in coronary bypass candidates. SUBJECTS AND METHODS: This cohort study included 107 consecutive candidates for coronary artery bypass surgery who underwent percutaneous coronary intervention with multiple coronary stents between Jan 2004 and Dec 2011. The study endpoint was major adverse cardiovascular events (MACEs) including all-cause mortality, nonfatal myocardial infarction, repeat revascularization, and stent thrombosis. Follow up was from the date of index percutaneous coronary intervention to the date of the first MACE, date of death, or December 31, 2015, whichever came first. RESULTS: In this study (age 62.3±11.2 years, 86% male), 38 patients (36%) had MACE. Among baseline, angiographic, and procedural parameters, there were significant differences in lower left ventricular ejection fraction (LVEF) and worse renal function. In a Cox regression model, LVEF and chronic kidney disease (CKD) were significant predictors for MACE. After a multivariate adjustment, CKD remained a significant predictor of MACEs (hazard ratio: 2.97, 95% confidence interval: 1.50-5.90). CONCLUSIONS: For coronary bypass candidates who were treated with coronary angioplasty and stenting, CKD seems to be the strongest predictor for adverse outcomes compared with other traditional factors.

Objective:
Tardive syndrome (TS) is an umbrella term used to describe a group of abnormal movement disorders caused by chronic exposure to dopamine receptor blocking agents. Few follow-up studies have been performed on the outcome of TS in patients using antipsychotics. The purpose of our study was to investigate the prevalence, incidence, remission rate, and factors associated with remission in patients using antipsychotics.
Methods:
This retrospective cohort study consisted of 123 patients who received continuous treatment of antipsychotics in a medical center in Taiwan, from April 1, 2011 to May 31, 2021. We assessed the demographic and clinical characteristics, prevalence, incidence, remission rate, and factors associated with remission in patients using antipsychotics.TS remission was defined as a Visual Analogue Scale score ≤ 3.
Results:
Of the 92 patients who completed the 10-year follow-up, 39 (42.4%) were found to have at least one episode of TS, with tardive dyskinesia (TD) being the most prevalent subtype (51.3%). With regard to concurrent physical illness, a history of extrapyramidal symptoms were significant risk factors for TS. During the 10-year follow-up period, the remission rate of TS was 74.3%. The use of antioxidants including vitamin B6 and piracetam was related to the remission of TS. Patients with tardive dystonia had a higher remission rate (87.5%) compared to TD (70%).
Conclusion
Our study suggests that TS may be a treatable condition, and the key to a better outcome is early detection and prompt intervention, including closely monitoring antipsychotics-related TS symptoms and using antioxidants.
