RESUMEN
BACKGROUND: The optimal duration of regimens for tailored therapy based on genotypic resistance for clarithromycin has yet to be established. AIM: This study was a nationwide, multicenter, randomized trial comparing empirical therapy with tailored therapy based on genotypic resistance for first-line eradication of Helicobacter pylori. We also compared the eradication rates of 7- and 14-day regimens for each group. PATIENTS AND METHODS: Patients with H. pylori infection were first randomized to receive empirical or tailored therapy. Patients in each group were further randomized into 7- or 14-day regimens. Empirical therapy consisted of a triple therapy (TT) regimen (twice-daily doses of pantoprazole 40 mg, amoxicillin 1 g, and clarithromycin 500 mg) for 7 or 14 days. Tailored therapy consisted of TT of 7 or 14 days in patients without genotypic resistance. Patients with genotypic resistance were treated with bismuth quadruple therapy (BQT) regimens (twice-daily doses of pantoprazole 40 mg, three daily doses of metronidazole 500 mg, and four times daily doses of bismuth 300 mg and tetracycline 500 mg) for 7 or 14 days. A 13C-urea breath test assessed eradication rates. The primary outcome was eradication rates of each group. RESULTS: A total of 593 patients were included in the study. The eradication rates were 65.7% (201/306) in the empirical therapy group and 81.9% (235/287) in the tailored therapy group for intention-to-treat analysis (p < 0.001). In the per-protocol analysis, the eradication rates of the empirical therapy and tailored groups were 70.3% (201/286) and 85.5% (235/274) (p < 0.001), respectively. There was no difference in compliance between the two groups. The rate of adverse events was higher in the tailored group compared to the empirical group (p < 0.001). DISCUSSION: Our study confirmed that tailored therapy based on genotypic resistance was more effective than empirical therapy for H. pylori eradication in Korea. However, no significant difference was found between 7- and 14-day regimens for each group. Future studies are needed to determine the optimal duration of therapy for empirical and tailored therapy regimens.

BACKGROUND: The quality-of-life of patients with irritable bowel syndrome is low; incorrect diagnosis/treatment causes economic burden and inappropriate consumption of medical resources. This survey-based study aimed to analyze the current status of irritable bowel syndrome treatment to examine differences in doctors' perceptions of the disease, and treatment patterns. METHODS: From October 2019 to February 2020, the irritable bowel syndrome and Intestinal Function Research Study Group of the Korean Society of Neurogastroenterology and Motility conducted a survey on doctors working in primary, secondary, and tertiary healthcare institutions. The questionnaire included 37 items and was completed anonymously using the NAVER platform (a web-based platform), e-mails, and written forms. RESULTS: A total of 272 doctors responded; respondents reported using the Rome IV diagnostic criteria (amended in 2016) for diagnosing and treating irritable bowel syndrome. Several differences were noted between the primary, secondary, and tertiary physicians' groups. The rate of colonoscopy was high in tertiary healthcare institutions. During a colonoscopy, the necessity of random biopsy was higher among physicians who worked at tertiary institutions. 'The patient did not adhere to the diet' as a reason for ineffectiveness using low-fermentable oligo-, di-, and mono-saccharides, and polyols diet treatment was higher among physicians in primary/secondary institutions, and 'There are individual differences in terms of effectiveness' was higher among physicians in tertiary institutions. In irritable bowel syndrome constipation predominant subtype, the use of serotonin type 3 receptor antagonist (ramosetron) and probiotics was higher in primary/secondary institutions, while serotonin type 4 receptor agonist was used more in tertiary institutions. In irritable bowel syndrome diarrhea predominant subtype, the use of antispasmodics was higher in primary/secondary institutions, while the use of serotonin type 3 receptor antagonist (ramosetron) was higher in tertiary institutions. CONCLUSION: Notable differences were observed between physicians in primary/secondary and tertiary institiutions regarding the rate of colonoscopy, necessity of random biopsy, the reason for the ineffectiveness of low-fermentable oligo-, di-, and mono-saccharides, and polyols diet, and use of drug therapy in irritable bowel syndrome. In South Korea, irritable bowel syndrome is diagnosed and treated according to the Rome IV diagnostic criteria, revised in 2016.

BACKGROUND: Eradication rate of standard triple therapy for H. pylori has declined to unacceptable level, and alternative regimens such as concomitant and sequential therapy have been introduced. We aimed to assess the consistency of eradication rates of concomitant and sequential therapies as for the first-line H. pylori eradication in Korea. METHODS: A nationwide multicenter retrospective study was conducted including 18 medical centers from January 2008 to December 2017. We included 3,800 adults who had test to confirm H. pylori eradication within 1 year after concomitant or sequential therapy. RESULTS: Concomitant and sequential therapy were prescribed for 2508 and 1292 patients, respectively. The overall eradication rate of concomitant therapy was significantly higher than that of sequential therapy (91.8% vs. 86.1%, p < .001). In time trend analysis, the eradication rates of concomitant therapy were 90.2%, 88.2%, 92.1%, 94.3%, 91.1%, and 93.4% for each year from 2012 to 2017 with an increasing trend (p = .0146), while those of ST showed no significant trend (p = .0873). Among 263 patients with second-line therapy, bismuth quadruple therapy showed significantly higher eradication rate than quinolone-based triple therapy (73.9% vs. 51.5% in ITT analysis, p = .001; 82.7% vs. 63.0% in PP analysis, p = .002). CONCLUSION: Concomitant therapy is the best regimen for the first-line H. pylori eradication showing consistently higher eradication rate with an increasing trend for the last 10 years in Korea. Bismuth quadruple therapy should be considered for second-line therapy after eradication failure using non-bismuth quadruple therapy.

BACKGROUND: The clinical pathway (CP) protocols simplified a systematic process from hospitalization to discharge, and were conducted to achieve standardization of the treatment process as well as improve outcomes. Thus, we investigated the optimal procedure-related hospitalization period following gastric endoscopic submucosal dissection (ESD) by comparing the rate of delayed bleeding (DB) and perforation according to CP protocols. METHODS: We retrospectively enrolled 630 patients who underwent ESD for gastric dysplasia or early gastric cancer (EGC); Group A (368 patients) followed Protocol A for a hospital stay of a single night; Group B (262 patients) followed Protocol B for a hospital stay of two nights. RESULTS: The patient characteristics were comparable between the two groups, except for pathologic diagnosis (42.1% in Group A vs. 32.1% in Group B for EGC). DB occurred in 21 patients, and there was no significant difference in the overall DB rates between Group A (12/368 = 3.3%) and Group B (9/262 = 3.4%) (P = 0.904). The DB rates were 2.5% (8/315) and 7.5% (4/53) in Group A, and 2.7% (6/223) and 7.7% (3/39) in Group B, without and with the use of antiplatelets, respectively, and 33.3% (1/3) in Group A and 50.0% (1/2) in Group B with the use of dual antiplatelets. DB developed at various intervals post-discharge from 2 to 17 days, and was successfully controlled by endoscopic hemostasis in most cases. There were no deaths or surgeries required as a result of uncontrolled DB and no postoperative delayed perforation occurred. CONCLUSIONS: The CP protocols with a one-night hospitalization following gastric ESD decreased the hospital stay and did not influence postoperative complications compared to those with two-night hospitalizations.

BACKGROUND: Indigo naturalis is a Chinese herbal medicine that has currently been used to treat various inflammatory diseases, including ulcerative colitis. Recently, there are several reports concerning severe adverse events associated with indigo naturalis. CASE PRESENTATION: We described a case of a 44-year-old female with ulcerative colitis who presented with lower abdominal pain and hematochezia. She stopped taking her medicine for ulcerative colitis and started oral indigo naturalis 3 months before admission. Computed tomography showed segmental edematous wall thickening of the descending and sigmoid colon. Colonoscopy findings revealed erythema, edema, and submucosal hemorrhage, the surface of which presented a dark blue pigmentation. The histologic finding was consistent with ischemic colitis. We therefore considered an ischemic colitis induced by indigo naturalis, and the patient improved after supportive care and withdrawal of indigo naturalis. CONCLUSION: Indigo naturalis has currently been used in the patients with ulcerative colitis as an alternative therapy. However, physicians should be aware of possible severe adverse events such as ischemic colitis.

BACKGROUND: Cholangiocarcinoma (CCA) is from cholangiocytes, and therefore bile is a potentially rich source of biomarkers for CCA. The aim of the study was to identify and validate microRNAs (miRNAs) in bile samples that are differentially expressed between benign biliary disease (BBD) and CCA. METHODS: Bile samples from 106 patients with obstructive biliary disease were allocated consecutively to a discovery set (10 patients with BBD and 11 with CCA) and then a validation set (48 patients with BBD and 37 with CCA). An miRNA microarray platform was used to screen 1209 miRNAs in the discovery set. Quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) was used to validate the profiling results in the discovery and validation sets. In addition, the levels of carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) were determined from patient serum samples. RESULTS: Microarray profiling showed that miR-30d-5p and miR-92a-3p were significantly upregulated in bile from the CCA group compared with those from the BBD group. qRT-PCR results indicated that the expression levels of miR-30d-5p and of miR-92a-3p were significantly upregulated in the CCA group compared to the BBD group, validating the miRNA microarray results. Pathway analysis suggested that putative target genes of miR-30d-5p and of miR-92a-3p were involved in CCA-associated signalling pathways, such as Hippo, Wnt, p53, MAPK, and EGFR. Receiver operating curve analysis revealed that the areas under the curve for bile miR-30d-5p, miR-92a-3p, serum CA19-9, and CEA were 0.730, 0.652, 0.675, and 0.603, respectively, and bile miR-30d-5p showed the best diagnostic performance with a sensitivity of 81.1% and a specificity of 60.5%. CONCLUSIONS: The levels of extracellular miR-30d-5p and miR-92a-3p in bile were significantly higher in patients with CCA than those in patients with BBD. Bile-derived circulating extracellular miR-30d-5p and miR-92a-3p are potential biomarkers for discriminating CCA from BBD.

INTRODUCTION: Signet ring cell carcinoma (SRC) is a poorly differentiated cancer of the stomach. Recent studies imply that early gastric SRC can be well managed by endoscopic resection. Unfortunately, unlike differentiated cancers, the endoscopic features of early gastric SRC have not been well studied. This study evaluated the endoscopic features of early gastric SRC, as well as the risk factors for submucosal (SM) invasion. METHOD: The medical records of patients from 7 tertiary hospitals (Daejeon and Chungcheong province) were reviewed to examine endoscopic findings and clinical data. These patients underwent surgery or endoscopic resection between January 2011 and December 2016 and were divided into 2 groups (derivation group and validation group) in order to develop and validate an endoscopic scoring system for SM invasion. RESULTS: In total, 331 patients (129 in the derivation group and 202 in the validation group) were enrolled in this study. In the derivation group, the risk factors for SM invasion, namely, fold convergence, nodular mucosal change, and deep depression, were identified by logistic regression analysis (ORs 3.4, 5.9, and 6.0, p < 0.05). A depth-prediction score was created by assigning 1 point for fold convergence and 2 points for other factors. When validation lesions of 0.5 point or more were diagnosed as SM invasion, the sensitivity and specificity were 76.8-78.6% and 61.6-74.7% respectively. CONCLUSION: Fold convergence, nodular mucosal change, and deep depression are risk factors for SM invasion in early gastric SRC. Our depth-prediction scoring system may be useful for differentiating SM cancers.

BACKGROUND: Acute cholangitis in old people is a cause of mortality and prolonged hospital stay. We evaluated the effects of methods and timing of biliary drainage on the outcomes of acute cholangitis in elderly and very elderly patients. METHODS: We analyzed 331 patients who were older than 75 years and were diagnosed with acute calculous cholangitis. They were admitted to our hospital from 2009 to 2014. Patients' demographics, severity grading, methods and timing of biliary drainage, mortality, and hospital stay were retrospectively obtained from medical records. Clinical parameters and outcomes were compared between elderly (75-80 years, n=156) and very elderly (≥81 years, n=175) patients. We analyzed the effects of methods [none, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic biliary drainage, or failure] and timing (urgent or early) of biliary drainage on mortality and hospital stay in these patients. RESULTS: Acute cholangitis in older patients manifested as atypical symptoms characterized as infrequent Charcot's triad (4.2%) and comorbidity in one-third of the patients. Patients were graded as mild, moderate, and severe cholangitis in 104 (31.4%), 175 (52.9%), and 52 (15.7%), respectively. Urgent biliary drainage (≤24 hours) was performed for 80.5% (247/307) of patients. Very elderly patients tended to have more severe grades and were treated with sequential procedures of transient biliary drainage and stone removal at different sessions. Hospital stay was related to methods and timing of biliary drainage. Mortality was very low (1.5%) and not related to patient age but rather to the success or failure of biliary drainage and severity grading of the acute cholangitis. CONCLUSIONS: The methods and timing used for biliary drainage and severity of cholangitis are the major determinants of mortality and hospital stay in elderly and very elderly patients with acute cholangitis. Urgent successful ERCP is mandatory for favorable prognosis in these patients.

BACKGROUND: Little is known about disparities in diagnosis and treatment among colorectal cancer (CRC) patients with and without disabilities. AIM: To investigate the patterns of diagnosis, treatment, and survival for people with and without disabilities who had CRC. METHODS: We performed a retrospective analysis using the Korean National Health Insurance Service database, disability registration data, and Korean Central Cancer Registry data. The analysis included 21449 patients with disabilities who were diagnosed with CRC and 86492 control patients diagnosed with CRC. RESULTS: The overall distribution of CRC stage was not affected by disability status. Subjects with disabilities were less likely than those without disabilities to undergo surgery [adjusted odds ratio (aOR): 0.85; 95% confidence interval (95%CI): 0.82-0.88], chemotherapy (aOR: 0.84; 95%CI: 0.81-0.87), or radiotherapy (aOR: 0.90; 95%CI: 0.84-0.95). The rate of no treatment was higher in patients with disabilities than in those without disabilities (aOR: 1.48; 95%CI: 1.41-1.55). The overall mortality rate was higher in patients with disabilities [adjusted hazard ratio (aHR): 1.24; 95%CI: 1.22-1.28], particularly severe disabilities (aHR: 1.57; 95%CI: 1.51-1.63), than in those without disabilities. CONCLUSION: Patients with severe disabilities tended to have a late or unknown diagnosis. Patients with CRC and disabilities had lower rates of treatment with almost all modalities compared with those without disabilities. During the follow-up period, the mortality rate was higher in patients with disabilities than in those without disabilities. The diagnosis and treatment of CRC need improvement in patients with disabilities.
RESUMEN
Ulcerative colitis (UC) poses a contemporary medical challenge, with its exact cause still eluding researchers. This is due to various factors, such as the rising incidence, diagnostic complexities, and difficulties associated with its management. We compared the intestinal microbiome of patients with UC to that of healthy controls to determine the qualitative and quantitative changes associated with UC that occur in the intestinal microbiota. The intestinal bacterial abundance in 40 Korean patients with UC and 25 healthy controls was assayed using via next-generation sequencing. There were five major phyla in both groups: Firmicutes (UC patients: 51.12%; healthy controls: 46.90%), Bacteroidota (UC patients: 37.04%; healthy controls: 40.34%), Proteobacteria (UC patients: 6.01%; healthy controls: 11.05%), Actinobacteriota (UC patients: 5.71%; healthy controls: 1.56%), and Desulfobacteriota (UC patients: 0.13%; healthy controls: 0.14%). Firmicutes was more prevalent in patients with UC (51.12%) compared to that of healthy controls (46.90%). Otherwise, Bacteroidota was more prevalent in healthy controls (40.34%) compared to patients with UC (37.04%). Although there was no significant difference, our results showed a substantially lower gut microbiome diversity in patients with UC (mean: 16.5; 95% confidence interval (CI) = 14.956-18.044) than in healthy controls (mean: 17.84; 95% CI = 15.989-19.691), the beta diversity and the flora structure of the microbiome in patients with UC differed from those in healthy controls. This will be helpful for the development of new treatment options and lay the groundwork for future research on UC. To understand the disease mechanism, it is essential to define the different types of microbes in the guts of patients with UC.
RESUMEN
Biliary hamartomas are tumor-like malformations of the liver. Biliary hamartomas are a type of fibrocystic disorder originating from ductal plate malformation and are typically considered benign, but with the risk of malignant transformation. In this case report, we present a rare occurrence of intrahepatic cholangiocarcinoma (ICC) that developed from biliary hamartomas, along with a literature review. A 76-year-old man with a diagnosis of biliary hamartomas had a history of recurrent cholangitis for 12 years, necessitating cholecystectomy, ERCP, and repeated antibiotic treatments. During his last episode, imaging studies revealed a hypervascular infiltrative mass in the right posterior liver segment. A liver biopsy confirmed adenocarcinoma and subsequent surgical pathology revealed ICC originating from biliary hamartomas. Chronic inflammation in the bile duct associated with biliary hamartomas may serve as a potential trigger for malignant transformation, as observed in this case. Therefore, close surveillance is essential for patients with biliary hamartomas presenting with infectious complications.

We aimed to evaluate the incidence and risk of pancreatic cancer (PC) in pancreatitis. We identified patients with acute pancreatitis (AP) (n = 225,811, 50.0%) and chronic pancreatitis (CP) (n = 225,685, 50.0%) from Korean population-based data and matched them with age- and sex-matched controls (n = 4,514,960). We analyzed the incidence and adjusted hazard ratios (aHRs) of PC among patients followed for more than 2 years or 5 years, and assessed risk changes over time in single episode of AP (SAP), recurrent AP (RAP), CP with AP, and CP without AP groups. We also performed subgroup analysis for both sexes. The incidences (per 104 person-years) and risks (aHR) of PC were higher in the RAP (12.69, 5.00) or CP with AP (12.12, 5.74) groups compared to the SAP (2.31, 1.32) or CP without AP (2.28, 1.57) groups. The risks of PC decreased over time, however, the risk of PC remained elevated in the RAP and CP with AP groups for more than 8 years. Females with RAP, SAP, and CP with AP had higher risks of PC than males. The risk of PC is higher and persists for longer duration in patients with RAP and CP with AP compared to those with SAP or CP without AP.

Background/Aims: Papillary adenocarcinoma is classified to differentiated-type gastric cancer and is indicated for endoscopic submucosal dissection. However, due to its rare nature, there are limited studies on it. The purpose of this study was to determine the outcome of endoscopic submucosal dissection in patients with papillary-type early gastric cancer and to find the risk factors of lymph node metastasis. Methods: Patients diagnosed with papillary-type early gastric cancer at eight medical centers, who underwent endoscopic submucosal dissection or surgical treatment, were retrospectively reviewed. The clinical results and long-term outcomes of post-endoscopic submucosal dissection were evaluated, and the risk factors of lymph node metastasis in the surgery group were analyzed. Results: One-hundred and seventy-six patients with papillary-type early gastric cancer were enrolled: 44.9% (n=79) in the surgery group and 55.1% (n=97) in the endoscopic submucosal dissection group. As a result of endoscopic submucosal dissection, the en bloc resection and curative resection rates were 91.8% and 86.6%, respectively. The procedure-related complication rate was 4.1%, and local recurrence occurred in 3.1% of patients. Submucosal invasion (odds ratio, 3.735; 95% confidence interval, 1.026 to 12.177; p=0.047) and lymphovascular invasion (odds ratio, 7.636; 95% confidence interval, 1.730 to 22.857; p=0.004) were the risk factors of lymph node metastasis in papillary-type early gastric cancer patients. Conclusions: The clinical results of endoscopic submucosal dissection in papillary-type early gastric cancer were relatively favorable, and endoscopic submucosal dissection is considered safe if appropriate indications are confirmed by considering the risk of lymph node metastasis.
RESUMEN
BACKGROUND/AIMS: The number of endoscopic procedures and related adverse events is increasing. We investigated South Korean endoscopists' awareness and experience of endoscopic adverse events. MATERIALS AND METHODS: We used Google Forms to conduct an online questionnaire survey among South Korean endoscopists from December 11 to 29, 2020. The survey comprised 30 questions developed by members of the Quality Management Committee of the Korean Society of Gastrointestinal Endoscopy. RESULTS: In total, 475 endoscopists participated in the survey. Of these, 454 (95.6%) were board-certified gastroenterologists and 255 (53.7%) had >10 years of endoscopy experience. Most participants had experienced serious adverse events requiring hospitalization (80.4%, 382/475); however, only 100 (21.1%) were aware of programs for the prevention and management of adverse endoscopic events in their affiliated endoscopy centers. Most participants (98.5%, 468/475) agreed with the need for education on medical accidents for healthcare workers. Responses were inconsistent regarding the definition of adverse events formulated by the 2010 American Society for Gastrointestinal Endoscopy Workshop. Most participants were not aware of the minimal standard terminology (76.6%, 364/475) and had not used it when writing endoscopy reports (88.8%, 422/475). Responses were inconsistent regarding which events to record in endoscopy records. CONCLUSION: Further discussion on the nationwide adverse-event reporting system and education program for adverse events related to endoscopy is needed to ensure the safety of patients and endoscopists.

Background/Aims: Fexuprazan is a novel potassium-competitive acid blocker that could be of benefit to patients with gastric mucosal injury. The aim of this study was to assess the 2-week efficacy and safety of fexuprazan in patients with acute or chronic gastritis. Methods: In this study, 327 patients with acute or chronic gastritis who had one or more gastric erosions on endoscopy and subjective symptoms were randomized into three groups receiving fexuprazan 20 mg once a day (q.d.), fexuprazan 10 mg twice a day (b.i.d.), or placebo for 2 weeks. The posttreatment assessments were the primary endpoint (erosion improvement rate), secondary endpoints (cure rates of erosion and edema and improvement rates of redness, hemorrhage, and subjective symptoms), and drug-related adverse events. Results: Among the patients, 57.8% (59/102), 65.7% (67/102), and 40.6% (39/96) showed erosion improvement 2 weeks after receiving fexuprazan 20 mg q.d., fexuprazan 10 mg b.i.d., and placebo, respectively. Both fexuprazan 20 mg q.d. and 10 mg b.i.d. showed superior efficacy to the placebo (p=0.017 and p<0.001, respectively). Likewise, both fexuprazan 20 mg q.d. and 10 mg b.i.d. also showed higher erosion healing rates than the placebo (p=0.033 and p=0.010, respectively). No difference was noted in the edema healing rate and the improvement rates for redness, hemorrhage, and subjective symptoms between the fexuprazan and placebo groups. No significant difference was noted in the incidence of adverse drug reactions. Conclusions: Fexuprazan 20 mg q.d. and 10 mg b.i.d. for 2 weeks showed therapeutic efficacy superior to that of placebo in patients with acute or chronic gastritis (ClinicalTrials.gov identifier NCT04341454).

Background/Aims: It remains unclear which maintenance treatment modality is most appropriate for mild gastroesophageal reflux disease (GERD). We aimed to compare on-demand treatment with continuous treatment using a proton pump inhibitor (PPI) in the maintenance treatment for patients with non-erosive GERD or mild erosive esophagitis. Methods: Patients whose GERD symptoms improved after 4 weeks of standard dose PPI treatment were prospectively enrolled at 25 hospitals. Subsequently, the enrolled patients were randomly assigned to either an on-demand or a continuous maintenance treatment group, and followed in an 8-week interval for up to 24 weeks. Results: A total of 304 patients were randomized to maintenance treatment (continuous, n = 151 vs on-demand, n = 153). The primary outcome, the overall proportion of unwillingness to continue the assigned maintenance treatment modality, failed to confirm the non-inferiority of on-demand treatment (45.9%) compared to continuous treatment (36.1%). Compared with the on-demand group, the GERD symptom and health-related quality of life scores significantly more improved and the overall satisfaction score was significantly higher in the continuous treatment group, particularly at week 8 and week 16 of maintenance treatment. Work impairment scores were not different in the 2 groups, but the prescription cost was less in the on-demand group. Serum gastrin levels significantly elevated in the continuous treatment group, but not in the on-demand group. Conclusions: Continuous treatment seems to be more appropriate for the initial maintenance treatment of non-erosive GERD or mild erosive esophagitis than on-demand treatment. Stepping down to on-demand treatment needs to be considered after a sufficient period of continuous treatment.
RESUMEN
Ceftriaxone is widely used in patients for the treatment of serious gram-negative infections. Ceftriaxone can induce some potential side effects, including neurotoxicity, however, nonconvulsive status epilepticus has rarely been reported. We report a case of acute reversible neurotoxicity associated with ceftriaxone. A 65-yr-old woman with chronic kidney disease developed altered consciousness during ceftriaxone treatment for urinary tract infection. The electroencephalogram demonstrated continuous bursts of generalized, high-voltage, 1 to 2 Hz sharp wave activity. Neurologic symptoms disappeared following withdrawal of ceftriaxone. The possibility of ceftriaxone-induced neurotoxicity should be considered in patients developing neurological impairment during ceftriaxone use, and the discontinuation of the drug could lead to complete neurological improvement.

A 91-year-old woman who presented with melena and hypovolemic shock visited the emergency room. She received enteral nutrition by nasogastric tube in a bedridden state due to hip surgery. Gastroscopy initially suggested a simple ulcer that occurred after a nasogastric tube was placed for a long time, but the ulcer was deep, and the amount of instantaneous bleeding was considerable. Therefore, an aortoesophageal fistula was suspected. Angiography was performed instead of endoscopic hemostasis, followed by thoracic endovascular aortic repair (TEVAR). After the TEVAR procedure, the patient recovered without further gastrointestinal bleeding. Prompt judgment and communication between the endoscopist and the interventional physician are important for successful hemostasis in an aortoenteric fistula patient.

Vitamin D is considered to be the main mediator of the beneficial effects of sun exposure. In humans, highest expression of Vitamin D receptors is found in the intestinal tract. In addition, 1α,25-dihydroxyvitamin D3 (or calcitriol), the most active Vitamin D metabolite, plays important homeostatic roles in the intestine, particularly calcium absorption. Vitamin D deficiency is defined as a serum 25-hydroxyvitamin D [25(OH)D] level of < 20 ng/mL. Previous studies show that higher circulating 25(OH)D levels are associated with reduced risk of colorectal cancer (CRC) and improved survival. Most research to date has been conducted in animals, specifically mice. Although human studies have a limited number of participants, one study recruiting a large cohort of patients with advanced or metastatic CRC revealed that higher plasma 25(OH)D levels are associated with improved overall and progression-free survival. However, the effects of Vitamin D supplementation on incidence and mortality of CRC remain inconclusive. Although Vitamin D may help to prevent cancer, there is a paucity of research demonstrating conclusively that Vitamin D alters prognosis after chemotherapy. Here, we review the mechanisms by which Vitamin D affects CRC, as well as the results of clinical, epidemiological, and human intervention studies. We also discuss current perspectives and future directions regarding Vitamin D and CRC.
RESUMEN
The prognosis of early gastric cancer (EGC) with submucosal invasion is favorable; however, several cases of recurrence have been reported even after curative gastrectomy. This study aimed to investigate risk factors and evaluate the clinical significance of the number of retrieved lymph nodes (LNs) in EGC with submucosal invasion. We retrospectively analyzed the data of 443 patients with gastric cancer with submucosal invasion after curative gastrectomy for recurrent risk factors. Recurrence was observed in 22 of the 443 gastric cancer patients with submucosal invasion. In the univariate analysis, the risk factors for recurrence were the number of retrieved LNsâ ≤â 25 and node metastasis. In the multivariate analysis, retrieved LNsâ ≤â 25 (hazard ratio [HR]â =â 5.754, P-valueâ =â .001) and node metastasis (HRâ =â 3.031, P-valueâ =â .029) were independent risk factors for recurrence after curative gastrectomy. Body mass index was related to retrieved LNsâ ≤â 25 in univariate and multivariate analyses (HRâ =â .510, Pâ =â .002). The number of retrieved LNs and node metastases were independent risk factors for EGC with submucosal invasion. For EGC with submucosal invasion, retrieved LNsâ >â 25 are necessary for appropriate diagnosis and treatment.
