Helicobacter pylori (H. pylori) infection involves the development of gastric cancer and may be associated with laryngeal cancer. However, laryngeal H. pylori infection in Taiwanese patients with newly diagnosed laryngeal cancer has not been reported. This study was aimed to investigate the possible association between laryngeal H. pylori infection and laryngeal cancer in Taiwan and perform a systematic review of previous reports in other countries. An analysis of 105 patients with laryngeal lesions found the positive rates of H. pylori DNA (determined by polymerase chain reaction) and antigen (determined by immunohistochemistry) of the laryngeal lesions were relatively low (vocal polyps: 3% and 3%; vocal fold leukoplakia: 0% and 0%; laryngeal cancers: 0% and 2%). Furthermore, H. pylori-associated laryngopharyngeal reflux and the expression of E-cadherin and CD1d (determined by immunohistochemistry) were comparable among the three subgroups. Fifteen studies were involved in the systematic review of the digital literature database, distributed to February 2021. The data of patients with laryngeal cancer and controls showed that the laryngeal H. pylori infection rates were 29.4% and 16.7%, respectively. Although current evidence supported that laryngeal H. pylori infection was associated with laryngeal cancer globally, it might not play a role in the development of laryngeal cancer in Taiwan.

We conducted a study to determine the presence or absence of Helicobacter pylori and laryngopharyngeal reflux (LPR) in 43 previously untreated patients who had presented with a laryngeal lesion. Our aim was to determine if there was any association among H pylori, LPR, and laryngeal lesions. H pylori status was determined by real-time polymerase chain reaction (PCR) assays of biopsy tissue obtained during direct laryngoscopy. The presence or absence of LPR was determined on the basis of patients’ reflux symptom index (RSI) and reflux finding score (RFS), which were based on their questionnaire responses and findings on endoscopic examination of the larynx, respectively. Patients with an RSI of 14 or more and/or an RFS of 8 or more were considered to have LPR. H pylori was present in 24 patients (55.8%) and absent in 19 (44.2%)—not a statistically significant difference. The prevalence of LPR was higher than the prevalence of H pylori; it was present in 30 patients (69.8%) and absent in 13 (30.2%). The difference was statistically significant (p = 0.01). We found no association between H pylori status and LPR status. Additionally, we analyzed two subgroups based on whether their lesions were benign or malignant/premalignant and found a significant relationship between LPR positivity and the presence of malignant/premalignant laryngeal lesions (p = 0.03). We found no association between H pylori status and either of the two subgroup categories.

Abstract Background Due to improved imaging sensitivity, the term “oligometastatic” prostate cancer disease is diagnosed more often, leading to an increasing interest in metastasis-directed therapy (MDT). There are two types of radiation based MDT applied when treating oligometastatic disease: (1) stereotactic body radiation therapy (SBRT) generally used for bone metastases; or (2) SBRT for isolated nodal oligometastases combined with prophylactic elective nodal radiotherapy. This review aims to summarize current evidence data, which may shed light on the optimal management of this heterogeneous group of patients. Methods A systematic review of the Medline database through PubMed was performed according to PRISMA guidelines. All relevant studies published up to November 2020 were identified and screened. Fifty-six titles were included. Besides outcome parameters, different prognostic and predictive factors were assessed, including site of metastases, time between primary treatment and MDT, use of systemic therapies, hormone sensitivity, as well as pattern of recurrence. Findings Evidence consists largely of retrospective case series and no consistent precise definition of oligometastasis exists, however, most investigators seem to acknowledge the need to distinguish between patients presenting with what is frequently called “synchronous” versus “metachronous” oligometastatic disease. Available data on radiotherapy as MDT demonstrate high local control rates and a small but relevant proportion of patients without progressive disease after 2 years. This holds true for both hormone sensitive and castration resistant prostate cancer diseases. The use of 68Ga-PSMA PET/CT for staging increased dramatically. Radiation doses and field sizes varied considerably among the studies. The search for relevant prognostic and predictive factors is ongoing. Conclusions To our best knowledge this review on oligometastatic prostate cancer included the largest number of original articles. It demonstrates the therapeutic potential and challenges of MDT for oligometastatic prostate cancer. Prospective studies are under way and will provide further high-level evidence.

Aim: Helicobacter pylori (H. pylori) infection and periodontitis have considerable worldwide prevalence once they both present systemic alterations with a possible association between them. Therefore, we have performed this meta-analysis to assess the possible association between H. pylori infection and periodontitis. Material and Methods: A systematic search in the literature was performed for studies published before December 2, 2019 in diverse scientific and educational databases. The data was extracted by two investigators and the statistical analysis was performed by Review Manager statistical program with heterogeneity and Odds Ratio (OR) with 95% of Confidence Intervals (CI) calculations as well as a sensitive analysis to assess the accuracy of the results. The value of P<0.05 was considered as significant. In addition, we performed the analysis of the quality of included studies as well as the evaluation for risk of bias. Results: In overall analysis, H. pylori infection was associated with the risk of periodontitis development (OR = 1.72, CI: 1.47, 2.02, P<0.00001) and the periodontitis was considered as a risk factor for H. pylori infection (OR = 3.21, CI: 2.31, 4.47, P<0.00001). Moreover, the evaluation of dental plaque from patients with periodontitis reveled increased risk of H. pylori infection (OR = 3.46, CI: 2.39, 5.01, P<0.00001). Conclusions: This current systematic review and meta-analysis composed by 12 studies in 7,059 participants showed that H. pylori infection increased significantly the risk of the development of periodontitis and the periodontitis may be a risk for this bacterial infection.

Background: Helicobacter pylorus is one of the most harmful human pathogens & carcinogen. Of the world's population, more than 50% has H. pylori in their upper gastrointestinal tracts. It has been linked to a variety of extra gastric disorders. In correlation to hepatobiliary diseases; recently, the bacterium has been implicated as a risk factor for various diseases ranging from chronic cholecystitis and primary biliary sclerosing cholangitis to gall bladder cancer and primary hepatic carcinomas. However, the association between Helicobacter pylori (H. pylori) and gallbladder diseases is still vague and is controversial. Aim of study: To elucidate the association of H pylori and gallbladder diseases (calculus, acalculous, polyp), the feasibility of using rapid urease test in post-operative diagnosis, and many factors related bacterium. Subjects & methods: This case series study was conducted in Al-Kindy Teaching hospital - surgical unit during a period extended for 2 years from September 2016 to September 2018, where patients suffered from signs and symptoms of gallbladder disease were interviewed using a predesigned questionnaire including age, gender, occupation, residency and whether the drinking water was safe (purified) or not. Physical examination was done including weight status, BMI was calculated (BMI=wt. (kg)/ height (M) [2]. Provisional diagnosis of gallbladder disease was confirmed by examination, necessary laboratory investigations (Hematology, Biochemistry, and radiology). Cholecystectomy was done by using Laparoscopic cholecystectomy or open surgery. The presence of H.pylori in the mucosa of excised gallbladder was studied by using: 1) Rapid urease kit (HNAN C., LTD) 2) Histopathology & chemical analysis of associated gallstone Results: Seventy-eight patients undergoing cholecystectomy for symptomatic gallbladder disease, the gallbladder mucosa of 30 patients were tested positive for H. pylori with any one of the tests used in this study. The rapid urease test was sensitive 57.1% and specific 58.3 % of the cholecystectomies performed in our study. The mean age of studied patients was (34 ± 4 years). Females constitute 73.1% (57 out of the total 78 of patients). Of the studied cases; 26 patients (33.3%) were obese. Employee patients constitute 43 (55.1%) of patients, and 53 patients (67.9%) lived in urban areas. Purified water consumed by 61 (78.2%) of the studied population. Gallstones were detected in 56 (71.8%) of studied cases, acalculus chronically inflamed gallbladder was found in 20 (25.64%), and 2 cases (2.56%). were found to have gallbladder polyp. pylori infection was diagnosed in 30 (38.5%) of total cases (of the 56 calculus confirmed cases 48.2% were H.pylori positive, and of the 22 acalculus cases 13.6% H.pylori positive). Conclusion: Significant association is found between chronic calculus cholecystitis and H.pylori infection. While no significant association was found in correlation with acalculus cholecystitis and other gallbladder pathology. In regard to feasibility of using urease kit test, it is found that this test is sensitive 57.1%, and specific 58.3%, as such it is less accurate than histopathology study. Significant correlation was found between age, gender, weight status, and non-purified water source with H.pylori infection..

Abstract Background Conflicting results of recent studies on the association between Helicobacter pylori (H. pylori) infection and the risk of insulin resistance and metabolic syndrome explored the need for updated meta-analysis on this issue. Therefore, this systematic review aimed to estimate the pooled effect of H. pylori infection on the risk of insulin resistance and metabolic syndrome. Methods To identify case-control studies and cohort studies evaluating the association of H. pylori infection with insulin resistance and metabolic syndrome, a comprehensive literature search was performed from international databases including Medline (PubMed), Web of Sciences, Scopus, EMBASE, and CINHAL from January 1990 until January 2021. We used odds ratio with its 95% confidence interval (95%CI) to quantify the effect of case-control studies and risk ratio with its 95%CI for the effect of cohort studies. Results 22 studies with 206911 participants were included for meta-analysis. The pooled estimate of odds ratio between H. pylori infection and metabolic syndrome in case-control studies was 1.19 (95%CI: 1.05, 1.35; I2 = 0%), and in cohort studies, the pooled risk ratio was 1.31 (95%CI: 1.13, 1.51; I2 = 0%). Besides, case-control studies showed the pooled odds ratio of 1.54 (95%CI: 1.19, 1.98; I2 = 6.88%) for the association between H. pylori infection and insulin resistance. Conclusion A positive association was found between H. pylori infection and insulin resistance as well as metabolic syndrome, so planning to eliminate or eradicate H. pylori infection could be an effective solution to improve metabolic syndrome or insulin resistance, and vice versa.

Objectives: This systematic review compared platelet concentrates (PCs) versus hyaluronic acid (HA) or saline/Ringer’s solution injections as treatments of temporomandibular osteoarthritis and disc displacement in terms of pain and maximum mouth opening (MMO). Methods: PubMed, Cochrane, and Scopus were searched up to March 6, 2020. Inclusion criteria were randomized clinical trials (RCTs). Exclusion criteria were case series, observational studies, animal studies, and reviews. The Effective Public Health Practice Project (EPHPP) quality assessment tool was used to assess the risk of bias in the included studies. The weighted mean difference was used to compare the results. Results: Nine RCTs were included with a total of 407 patients. The numbers of joints treated were 262, 112, and 112 in the PC, HA, and saline groups, respectively. The quality of studies was rated as strong in 4 studies, moderate in 4 studies, and weak in 1 study. The meta-analysis revealed that PCs decreased pain visual analogue scale (VAS) scores compared to HA by an average of −1.11 (CI, −1.62 to −0.60; P < 0.0001) and −0.57 (CI, −1.55 to 0.41; P = 0.26) at 3 and 12 mo follow-up respectively. Also, the average decrease in pain scores with PC compared to saline was −1.33 (CI, −2.61 to −0.06; P = 0.04), −2.07 (CI, −3.46 to −0.69; P = 0.003), and −2.71 (CI, −4.69 to −0.72; P = 0.008) at 3, 6, and 12 mo, respectively. Regarding MMO measurements, PC was comparable to HA, but it was significantly better than saline after 3 and 6 mo [2.9 mm (CI,1.47 to 4.3; P < 0.0001), and 1.69 mm (CI, 0.13 to 3.25; P = 0.03) respectively]. Conclusion: PC reduces pain VAS scores compared to HA during the first 3 m after treatment, and when compared to saline, it reduces pain and increases MMO for longer durations. However, due to differences between groups regarding PC preparation protocols and study heterogeneity, further standardized RCTs are required. Knowledge Transfer Statement: This study provides researchers and clinicians with quantitative and qualitative analyses of the current evidence regarding the clinical outcomes of platelet concentrate injections in the treatment of temporomandibular joint osteoarthritis and disc displacement in terms of pain control and maximum mouth opening.

Clinical Complications

Background: It is estimated that between 50 and 89% of non-gonococcal urethritis is not caused by Chlamydia trachomatis. Associations between non-chlamydial non-gonococcal urethritis (NCNGU) with balanoposthitis, epididymo-orchitis and reactive arthritis have been suggested, but evidence to support these often-theoretical relationships is sparse and further investigation is called for. Concerns over increasing antimicrobial resistance has rendered the need for clarity over this question ever more pressing in recent years. A review of the current evidence on the complications of NCNGU in men is therefore urgently warranted. Objective: This systematic review summarizes and evaluates the available evidence that NCNGU, whether symptomatic or asymptomatic, causes the significant complications that are already well-recognized to be associated with non-gonococcal urethritis. These significant complications are epididymo-orchitis, balanoposthitis, and sexually-acquired reactive arthritis (Reiter's syndrome) including arthritis or conjunctivitis. Summary: We conducted a systematic review and qualitative synthesis using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. Five databases (PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and British Nursing Index) were searched. We included studies that measured clinical outcome after diagnosis of NCNGU in men. Bias was assessed using variations of the Newcastle-Ottawa scale. Data were extracted and entered into a pre-written data abstraction proforma. Seven peer-review studies were included. This included 2 retrospective cohort studies, 1 case series, 2 case reports and 2 cross-sectional studies. The studies described and analyzed 3 types of complication: balanitis, posthitis and/or meatitis; reactive arthritis and/or conjunctivitis; and epididymitis. All studies reported one or more complications. Key Messages: This review identifies an important avenue for future research: while the available evidence suggests that NCNGU has the potential to cause significant complications in men, with the strongest evidence existing for balanitis, posthitis and/or meatitis, the nature and significance of these relationships is far from clear. The findings of this review suggest that prospective, adequately powered research into whether there is a causal link between NCNGU and significant clinical complications in men would be highly worthwhile. The findings of this review raise important questions about the utility of the term NCNGU in research and clinical practice.

Background: The recent introduction of 445 nm blue laser to office-based laryngology presents potential advantages. These include a desirable combination of cutting and photoangiolytic qualities and a lightweight, shock-resistant design. Despite its increasing use, current evidence is limited to experimental data and case reports. Objectives: The authors present a case series and overview of office blue laser transnasal flexible laser surgery (TNFLS), considering indications, patient selection, safety, technique, and surgical outcomes. We also review the safety and relevance of TNFLS to the ongoing coronavirus pandemic. Methods: Retrospective case series and narrative review. Our primary outcome measure was preoperative and postoperative Voice Handicap Index (VHI-10) score. Complications were documented by nature and severity. Results: Thirty-six cases of office blue laser TNFLS were performed. A statistically significant improvement in VHI-10 score was demonstrated in cases of recurrent respiratory papillomatosis (RRP) and benign laryngeal lesions causing dysphonia ( P < 0.01 and 0.045). Blue laser also proved effective in assisting office biopsy procedures. A minor and self-limiting complication was reported. Conclusions: Office blue laser TNFLS is safe and effective in the treatment of RRP and a range of benign laryngeal lesions. Future research should compare the efficacy and safety of blue laser with potassium titanyl phosphate laser in office-based treatment of these conditions. Further assessment of the cutting qualities of blue laser, initially in the theater environment, is necessary to refine our understanding of future applications.

Helicobacter Pylori Eradication Therapy

Evidence relating to the efficacy of Helicobacter pylori eradication therapy for chronic immune thrombocytopenic purpura (cITP) in childhood is inadequate. The aim of this retrospective study was to determine the efficacy of H. pylori eradication therapy for platelet response in pediatric patients with cITP in our hospital, and to perform a systematic review of previous reports about pediatric patients with cITP who were positive for H. pylori infection and were treated with H. pylori eradication therapy. Analysis of the data of pediatric patients with cITP in our hospital and a systematic review of digital literature databases of studies in pediatric patients with cITP were performed. Data of 33 pediatric patients with cITP from our hospital records showed that the prevalence of H. pylori infection and the rate of response to platelet therapy were 15% and 33.3%, respectively. Data of 706 pediatric patients from 18 previous reports showed that the prevalence of H. pylori infection and rate of platelet response were 23% and 43.8%, respectively. Eradication therapy for H. pylori infection in pediatric cITP patients can be expected to result in a response equivalent to that in the adult population, with fewer adverse effects than other treatments for cITP.
