Schlemm's canal stent insertion is a procedure for controlling the intraocular pressure by inserting a stent in the anterior chamber in patients with open-angle glaucoma. The objective of this review is to evaluate the safety and effectiveness of Schlemm's canal stent insertion for glaucoma. Searches of key databases, including 8 Korean databases, Medline, Embase, and Cochrane Library, were searched. Among 249 articles located in the search, a total of 14 studies (4 randomized controlled trials and 10 case series) were included in this review. Two review authors independently selected the studies and assessed their quality. On the basis of current data, we recommend that Schlemm's canal stent insertion is safe and effective for reducing intraocular pressure and the number of anti-glaucoma medications being administered for patients with open angle glaucoma.

Colonic arteriovenous malformation (AVM) is one of the causes of lower gastrointestinal bleeding. Unlike small vascular ectasia or angiodysplasia, colonic AVM tends to be solitary, large in size, and identified endoscopically as flat or elevated bright red lesion. Herein, we report a case of non-solitary and small cecal AVMs which were removed by endoscopic biopsy. A 66-yr-old woman was referred for routine gastrointestinal cancer screening. She was suffering from diabetes, hypertension, end-stage renal disease, and anemia of chronic disease. On colonoscopic finding, three semi-pedunculated polyps, less than 5 mm in size, were noticed near to the appendiceal orifice. Since the lesions revealed normal-looking epithelium with converging folds on the cecal base, lesions were diagnosed as inflammatory polyps on gross finding. Three biopsies were taken from each lesion. Bleeding from the biopsied site ceased spontaneously. Histopathologic evaluation demonstrated intramucosal hemorrhage and dilated submucosal vessels which were consistent with polypoid colonic AVMs.

The recovery of quadriceps muscle strength and knee function after knee surgery is important. Recently, neuro-muscular electrical stimulation (NMES), which is a method in which an electrical current is applied to the surrounding targeted muscle, has been incorporated into muscle-strengthening programs. The objective of this review was to evaluate the safety and effectiveness of NMES in patients who have undergone knee surgery. A database search was performed in 8 Korean databases, Medline, Embase, and the Cochrane Library. Article selection and quality assessment were performed by 2 reviewers. Of the 580 articles selected, 14 papers (randomized controlled trials) were included in the final assessment. In the results of the meta-analysis, NMES combined with rehabilitation demonstrated a significant improvement in the enhancement of quadriceps muscle strength after anterior cruciate ligament reconstruction. On the basis of the currently available data, NMES with rehabilitation is associated with favorable outcomes, and should be considered a safe and effective procedure for enhancing quadriceps muscle strength.

Background: Hearing loss (HL) is the most common chronic disease and has been linked to negative health outcomes. Hearing aids (HAs) are regarded as the gold standard for HL management, however, the adoption rate of HAs is relatively low for various reasons. With this background, hearing devices, such as personal sound amplification products (PSAPs) received significant attention as an alternative to conventional HAs. This study aimed to evaluate the clinical efficacy of PSAPs in patients with mild to moderately severe HL. Methods: Nineteen patients with mild hearing loss (MHL), 23 with moderate hearing loss (MDHL), and 15 with moderately severe hearing loss (MSHL) participated in the study.Electroacoustic analysis, simulated real-ear measurements (REMs), and three clinical evaluations were implemented. Results: All devices satisfied the electroacoustic tolerances. All devices provided sufficient gain for MHL and MDHL audiograms. However, in MSHL audiogram, the gains of PSAPs were insufficient, especially for high frequencies. In terms of clinical evaluations, soundfield audiometry showed significant improvements between aided and unaided thresholds in all groups for all devices (P < 0.001). Significant improvements of word recognition scores were only shown for HAs between aided and unaided conditions. The Korean version of the Hearing In Noise Test did not show any consistent findings for all devices and groups. Conclusion Certain PSAPs are beneficial for improving hearing and speech perception in patients with HL. Well-chosen PSAPs could be an alternative hearing rehabilitation option for these patients.

Objectives: This study aims to assess the effectiveness of early interventions in preventing psychosis transition, promoting remission, and reducing hospitalization rates in individuals at high risk for psychosis and those with recent onset psychosis (ROP). Methods: A systematic review and meta-analysis were conducted, comparing early intervention strategies such as cognitive-behavioral therapy and psychosocial support to no intervention. The study focused on outcomes related to psychosis transition, remission rates, and prevention of psychiatric hospitalization. Results: Although only a subset of clinical high risk (CHR) individuals transition to full psychosis, non-pharmacological treatments like cognitive-behavioral therapy are generally recommended as a first-line approach. In ROP patients, early pharmacological treatment reduces relapse rates, while psychosocial interventions aim to improve various functional outcomes. The meta-analysis results of this study did not show a significant reduction in psychosis transition rates with specialized interventions for CHR patients. For ROP patients, early interventions initially reduced hospitalization rates, but this effect was not sustained in mid-term follow-up results. Conclusion While early interventions offer short-term benefits in reducing psychosis transition and hospitalization, additional research is needed to determine their long-term effectiveness in functional recovery and overall patient outcomes.

Endoscopic hemostasis is the first-line treatment for upper gastrointestinal bleeding (UGIB). Although several factors are known to be risk factors for rebleeding, little is known about the use of antithrombotics. We tried to verify whether the use of antithrombotics affects rebleeding rate after a successful endoscopic hemostasis for peptic ulcer disease (PUD). UGIB patients who underwent successful endoscopic hemostasis were included. Rebleeding was diagnosed when the previously treated lesion bled again within 30 days of the initial episode. Of 522 UGIB patients with PUD, rebleeding occurred in 93 patients (17.8%). The rate of rebleeding was higher with aspirin medication (P=0.006) and after a long endoscopic hemostasis (P<0.001). Of all significant variables, procedure time longer than 13.5 min was related to the rate of rebleeding (OR, 2.899; 95% CI, 1.768-4.754; P<0.001) on the logistic regression analysis. The rate of rebleeding after endoscopic hemostasis for PUD is higher in the patients after a long endoscopic hemostasis. Endoscopic hemostasis longer than 13.5 min is related to rebleeding after a successful endoscopic hemostasis for PUD.

BACKGROUND/AIMS: Improvements in the endoscopic evaluation and management of gastric cancer have made it possible to determine the depth of invasion during endoscopic examination. The aim of this study was to elucidate the differences between early gastric cancer (EGC) that resembles advanced gastric cancer (AGC) and AGC that resembles EGC. METHODS: We retrieved cases of EGC-like AGC and AGC-like EGC from consecutive gastric cancers that had been completely resected. The endoscopic diagnoses and clinicopathological findings were analyzed. RESULTS: AGC-like EGCs were located mainly in the distal part of the stomach, whereas EGC-like AGCs were located mainly in the proximal part of the stomach (p<0.001). Sixty percent of AGC-like EGCs were moderately differentiated adenocarcinomas, while 64% of EGC-like AGCs were poorly differentiated adenocarcinomas (p=0.015). According to Lauren's classification, 68% of AGC-like EGCs were intestinal type, whereas 71% of EGC-like AGCs were diffuse type (p=0.020). CONCLUSIONS: AGC-like EGCs predominate in the distal part of the stomach, while EGC-like AGCs predominate in the proximal part. When evaluating the depth of a gastric cancer, care should be taken not to underestimate measurements in proximal gastric cancers since they tend to be poorly-differentiated adenocarcinomas, in Lauren's diffuse type, and invade deeper than their endoscopic appearance might suggest.
