Abstract PDF PubReader ePub: A 74-year-old male patient presented to our hospital for treatment of gastric cancer in 2021. He had previously visited our institution in 2011 for assessment of a gastric subepithelial lesion (SEL), which was discovered incidentally during a health screening esophagogastroduodenoscopy (EGD). Endoscopic ultrasonography and abdominal computed tomography were conducted for evaluation of the gastric SEL, revealing an approximately 1 cm lesion arising from the muscularis propria. The lesion was initially thought to represent a mesenchymal tumor such as leiomyoma or gastrointestinal stromal tumor. Owing to its small size and absence of symptoms, no immediate intervention was undertaken, and the patient underwent regular surveillance only. Follow-up was maintained until 2018 and no notable changes in the gastric SEL were detected. The patient then voluntarily discontinued further follow-up. In 2021, a routine health screening EGD identified changes in the gastric SEL, and histopathological analysis confirmed adenocarcinoma. The patient subsequently underwent radical total gastrectomy utilizing the Roux-en-Y technique, with the final pathological diagnosis being stage I (pT2N0M0) gastric cancer with lymphoid stroma (GCLS). As of April 2025, there has been no evidence of cancer recurrence. This case illustrates a lesion initially diagnosed as SEL that later was identified as GCLS after a 10-year interval. Therefore, during EGD, clinicians should consider the potential for SEL-like gastric cancer if an SEL is observed. This report highlights the importance of close monitoring and a thorough diagnostic evaluation.

Background
To address the public’s fear of coronavirus disease 2019 (COVID-19), understanding the clinical features of the disease is essential. However, research on the clinical features of COVID-19, including illness duration and post-acute COVID-19, in Korean pediatric patients has been limited. Therefore, this study investigated the clinical features of COVID-19 based on the medical records of pediatric patients with a history of COVID-19 who visited a single center.
Methods
In total, 311 patients were included in this study. The presence and duration of 19 symptoms were examined. Additionally, clinical features were investigated by dividing the patients into different age ranges. Patients aged 6 and above were further categorized according to the presence of asthma, while adolescent patients were divided into vaccinated and unvaccinated groups.
Results
Fever and cough were the most common symptoms. The mean illness duration was 2–4 days. Only 3.5% of the patients were asymptomatic. Post-acute COVID-19 was observed in 13.2% of the patients. The incidence of most symptoms tended to increase with age. Post-acute COVID-19 was observed more frequently in patients with asthma than in those without asthma. Vaccinated patients experienced less fever, vomiting, and fatigue than unvaccinated patients.
Conclusions
Our data suggest that most patients had mild disease lasting less than a week, and the clinical course may differ depending on the presence of asthma. The findings also indicate that vaccination may alleviate the symptoms of COVID-19 in breakthrough infections.

Background
Acute pulmonary thromboembolism (APTE) is often confused with myocardial infarction. Previous studies have shown that patients with APTE exhibit lower initial and peak cardiac troponin I (CTI) levels, but higher D-dimer (DD) levels, than patients with myocardial infarction. The present study aimed to reaffirm the tree model algorithm using an entirely new set of data.
Methods
We reviewed retrospective clinical and laboratory data from patients who were diagnosed with APTE or non-ST-elevation myocardial infarction (NSTEMI) between 2015 and 2016. Subjects who were not classified with a diagnosis or did not have their CTI or DD levels assessed were excluded. We categorized patients according to the previous algorithm and compared the outcomes with the previous test dataset.
Results
The analysis involved data from 156 patients with APTE and 363 patients with NSTEMI. In the validation data set, the APTE group showed higher initial DD levels (9.80±10.84 μg/mL) and lower initial CTI levels (0.17±0.54 μg/mL) than the NSTEMI group. The accuracy rate for the test dataset and the validation set were similar. The test set accuracy rate was 91.0%, while the accuracy rate in the validation set improved to 88.6%.
Conclusions
Patients with APTE exhibited lower initial and peak CTI levels, but higher DD levels than NSTEMI patients. The accuracy rate estimates were similar between the test set obtained from the tree model algorithm and the validation set. The study findings demonstrate that the assessment of cardiac biomarkers can be useful for differentiating between APTE and NSTEMI.

Abstract PDF PubReader ePub

The gut microbiota comprises a collection of microorganisms residing in the human digestive system, including bacteria, viruses, and fungi. These microbes have critical roles in food breakdown, immune system regulation, and the production of essential nutrients. Several lower gastrointestinal (GI) diseases, including inflammatory bowel disease, irritable bowel syndrome, and colorectal cancer, have been associated with dysbiosis, which refers to an imbalance in the gut microbiota. Additionally, the gut microbiome and its microbial compounds affect disease development and the host’s immune response. Alterations in the gut-brain axis microbiome are also implicated in lower GI diseases. Therefore, microbiome-based therapies that regulate the gut microbiota (e.g., fecal microbiota transplantation and probiotics) are essential for the prevention and treatment of these diseases. This review aims to highlight the significance of gut microbiota and microbiome-based therapies in managing lower GI diseases.

Background
Radiotherapy improves overall survival in patients with abdominopelvic malignancies. However, the toxic effects of radiation restrict the maximum dose that can be given, and there are no well-established preventive or therapeutic strategies. This study was conducted to evaluate whether rebamipide, sucralfate, and rifaximin have a suppressive effect on acute ionizing radiation (IR)-induced inflammation in the intestines of mice.
Methods
Thirty-six ICR mice were divided into a vehicle-treated group with sham irradiation; a vehicle-treated group with irradiation; rebamipide, sucralfate, or rifaximin-treated groups with irradiation; and a rebamipide-treated group with sham irradiation. The expression of proinflammatory, anti-inflammatory, proapoptotic, and antiapoptotic factors was investigated.
Results
The downregulated expression of nicotinamide phosphoribosyltransferase by IR was attenuated by all drugs (p<0.05). All drugs suppressed the IR-induced activation of NF-κB and phosphorylation of MAPKs (p<0.05) and attenuated the production of TNF-α, IL-1β, and IL-6 in response to IR (p<0.05). The administration of all drugs markedly attenuated IR-induced increases in iNOS, COX-2, and PGE2 (p<0.05), as well as [Ca2+] oscillations that were increased by IR. The expression of proapoptotic genes and antiapoptotic genes was suppressed and induced, respectively, by all drugs. IR treatment increased the release of cytochrome C, which was attenuated by all drugs (p<0.05). All drug treatments resulted in a significant decrease in the expression of caspase-3 and caspase-7 (p<0.05), which were both upregulated following IR treatment.
Conclusions
The administration of rebamipide, sucralfate, or rifaximin prior to radiation therapy may prevent or attenuate acute radiation-induced enterocolitis.

Background
Benign esophageal strictures are treated endoscopically, often with balloon dilatation (BD) or bougie dilators. However, recurrent esophageal strictures have been reported after BD, and severe complications sometimes occur. The aim of this study was to compare the efficacy and complications of endoscopic incisional therapy (EIT) and BD for benign esophageal strictures.
Methods
We retrospectively reviewed patients who underwent BD or EIT as primary treatment for benign esophageal strictures between July 2014 and June 2021. Technical success was defined as restoration of the lumen diameter with <30% residual stenosis. Clinical success was defined as no recurrence of dysphagia within 1 month after BD or EIT and an increase of 1 grade or more on the Functional Oral Intake Scale.
Results
Thirty patients with benign esophageal stricture were enrolled. There were 16 patients in the BD group and 14 patients in the EIT group. No significant differences in technical and clinical success rates were found between the two groups. Furthermore, no significant differences in the re-stricture rate were observed between the groups. There was one complication in the EIT group and three complications in the BD group. Three patients who underwent BD had re-stricture and underwent EIT thereafter, and we regrouped patients who underwent EIT at least once. The clinical success rate was significantly higher in patients regrouped to the EIT group than in patients who underwent BD only.
Conclusions
EIT is not inferior to BD as the primary treatment for benign esophageal strictures, especially for recurrent cases.

Abstract PDF PubReader ePub

Parathyroid carcinoma (PC) in cases of secondary or tertiary hyperparathyroidism is relatively uncommon, and only a few case reports have described this entity. Although some papers have reported patients with one or two parathyroid malignancies, multiple PC–especially three or more–have been even more rarely reported. Herein, we report a case of secondary hyperparathyroidism due to multiple PCs in a chronic hemodialysis patient. A 54-year-old man with end-stage kidney disease was referred for hyperparathyroidism. He had been diagnosed with chronic kidney disease in 2001 and had begun hemodialysis in 2009. In laboratory tests, intact parathyroid hormone (iPTH) was markedly elevated to 1,144.1 pg/mL (normal range: 15.0–68.3 pg/mL) and serum calcium was mildly elevated to 10.56 mg/dL (normal range: 8.5–10.3 mg/dL). Ultrasonography showed hypoechoic nodules in the posterior part of both thyroid glands. All three nodules showed increased uptake on a 99mTc sestamibi scan. The patient underwent total parathyroidectomy with autotransplantation to the right forearm. Histopathology findings showed three PCs with capsular invasion and one parathyroid hyperplasia. In the immediate postoperative period, the iPTH level dropped from 1,446.8 to 82.4 pg/dL and, after 1 month, to 4.0 pg/dL. This patient needed oral calcium carbonate and active vitamin D to maintain appropriate serum calcium levels. Although multiple PCs are rare, they can cause secondary hyperparathyroidism. Therefore, clinicians should suspect multiple PCs when patients’ serum iPTH levels are exceptionally high. Additionally, since PCs could occur in multiple glands, autotransplantation of the parathyroid gland after parathyroidectomy should be done carefully.

Abstract PDF PubReader ePub: Background
Nonalcoholic fatty liver disease dramatically improves after bariatric surgery, primarily due to improvements in hepatic insulin sensitivity. Since the procedure for gastric cancer surgery is very similar to that for bariatric surgery, we investigated changes in fatty liver following gastrectomy for gastric cancer according to the type of surgery.
Methods
We evaluated hepatic steatosis in 212 early gastric cancer patients using Hounsfield units (HUs) on non-contrast computed tomography preoperatively and 6, 12, and 24 months after surgery. We compared the preoperative and postoperative liver-to-spleen HU ratio according to the type of surgery: Billroth I, Billroth II, and total gastrectomy with Roux-en-Y reconstruction.
Results
The initial results (liver/spleen HUs and the liver-to-spleen HU ratio) did not significantly differ according to surgical group. After surgery, only patients who underwent total gastrectomy with Roux-en-Y exhibited significant changes in the liver-to-spleen HU ratio at 6 months. In 26 patients who had higher initial HU levels of the spleen than the liver, the liver-to-spleen HU ratio significantly increased from 0.836 to 1.115 at 6 months, 1.109 at 12 months, and 1.102 at 24 months (P<0.01).
Conclusion
Significant changes in hepatic steatosis were found in even normal patients (with higher liver than spleen HU values) who underwent total gastrectomy with Roux-en-Y. Patients who initially had fatty liver also showed a significant increase in the liver-to-spleen HU ratio. These results suggest that total gastrectomy with Roux-en-Y reconstruction can have a positive effect on the improvement of hepatic steatosis.

Comparison of the radiation dose between dual-acquisition coronary computed tomography angiography and coronary angiography for coronary spasm: Soo-Jin Kim, Moo Hyun Kim, Eun-Ju Kang; Kosin Med J. 2022;37(1):46-51. Published online March 16, 2022; DOI: https://doi.org/10.7180/kmj.21.035

Abstract PDF PubReader ePub: Background
Coronary computed tomography angiography (CCTA) is an imaging technique that can be used to evaluate and diagnose coronary artery stenosis. Dual-acquisition CCTA (DA-CCTA) with additional nitrate infusion is a promising alternative noninvasive diagnostic tool, as conventional CCTA has limitations in the diagnosis of variant angina compared to conventional angiographic coronary spasm tests. However, DA-CCTA may pose a potential risk due to radiation exposure. We compared the radiation dose between DA-CCTA and the coronary angiographic spasm provocation test.
Methods
Patients with clinically suspected variant angina at a single hospital between March 2013 and October 2018 were screened and underwent DA-CCTA or a coronary angiographic spasm provocation test. The effective radiation dose required for each approach was compared.
Results
In total, 211 suspected variant angina patients underwent DA-CCTA or the coronary angiographic spasm provocation test. Of these, 49 patients (mean age, 59.8 years; 67.3% men) received DA-CCTA and 162 patients (mean age, 60.5 years; 66.2% men) received a coronary angiographic spasm provocation test. There was a significant difference in the effective radiation dose, with a median dose of 5.1 mSv (interquartile range [IQR], 4.1–9.2 mSv) required for DA-CCTA and a median dose of 10.9 mSv (IQR, 8.4–15.2 mSv) for the coronary angiographic spasm provocation test (p<0.001).
Conclusion
DA-CCTA showed a significantly lower effective radiation dose than the coronary angiographic spasm provocation test required to diagnose variant angina.

Objectives

It is well known that type 2 diabetes (T2DM) is dramatically improved after bariatric surgery, although the mechanisms have not been clearly identified. The skill required for gastric surgery for gastric cancer is very similar to that needed in bariatric surgery. In this study, we evaluated the immediate improvement of T2DM after gastrectomy for gastric cancer.

Methods

A total of nine patients who were diagnosed with early gastric cancer (EGC) and already had T2DM underwent a 75 g oral glucose tolerance test (OGTT) before surgery and within two weeks after gastrectomy. Glucose, insulin, and c-peptide were measured before, and 30 and 60 minutes after ingesting 75 g of glucose. From these trials, we calculated the HOMA-IR, insulinogenic index, Matsuda index, and area under the curve (AUC).

Results

The mean age of participants was 57.23 ± 11.08 years and eight of them were men. HOMA-IR (4.2 vs. 2.3, P = 0.012) levels were decreased after surgery. There were no significant differences of insulinogenic index, fasting blood sugar before and after surgery. The Matsuda index (3.3 vs. 8.3, P = 0.002) was significantly increased and AUC (512.9 vs. 388.7 mg-hr/dL, P > 0.001) upon 75 g OGTT was significantly decreased after surgery.

Conclusions

Insulin sensitivity was immediately improved after gastrectomy for early gastric cancer in patients with T2DM.

Objectives

The FOURIER trial reported that inhibition of PCSK9 with evolocumab on a background of statin therapy lowered low-density lipoprotein (LDL) cholesterol levels to a median of 30 mg per deciliter (0.78 mmol per liter) and reduced the risk of cardiovascular events. Here, we report data from a single center focusing on the effect of a PCSK9 inhibitor antibody on hyperlipidemia.

Methods

We enrolled 29 hypercholesterolemia patients who had LDL cholesterol levels ≥ 70 mg per deciliter or non-HDL cholesterol ≥ 100 mg per deciliter and were divided into two groups (placebo n = 14, evolocumab n = 15), and participated in a 72 – 96 week, randomized, double-blind, placebo-controlled trial with statin therapy. Patients were randomly assigned to receive evolocumab (140 mg every 2 weeks or 420 mg monthly) or matched placebo via subcutaneous injection. Lipid changes during follow-up were analyzed.

Results

The median LDL cholesterol level at baseline was 88 mg per deciliter, and the average LDL cholesterol level was 101.8 ± 20.0 mg per deciliter. At 4 weeks, the median LDL cholesterol level was 39 mg per deciliter, and the average LDL cholesterol level was 34.8 ± 51.8 mg per deciliter. Compared to placebo group, the LDL cholesterol levels were significantly reduced after treatment (P < 0.001), as well as total cholesterol, ApoB, and ApoB/ApoA1 levels. During follow-up, no discomfort was reported at local injection sites, and no cases of abnormal liver function were observed.

Conclusions

Evolocumab significantly reduced LDL cholesterol levels and was well tolerated.

Objectives

: Since endoscopic findings of primary gastric lymphoma are ambiguous and diverse, it is not easy to distinguish them from gastric adenocarcinoma or secondary gastric lymphoma. The aim of this study was to investigate the difference in clinical and endoscopic features between primary gastric lymphoma and gastric involvement of lymphoma.

Methods

: Forty-eight patients were enrolled in this retrospective study between June 2008 and February 2017. The patients were divided into primary gastric lymphoma group (primary group, n = 18) and gastric involvement group (secondary group, n = 30) based on whether or not they carried gastric lesions alone. Patients’ clinical characteristics, endoscopic findings and pathologic data were retrospectively reviewed based on electronic medical records.

Results

: The mean age of patients was 63.3 ± 13.1 years and 29 patients were female (60.4%). Diffuse large B-cell lymphoma pathology (81.3%), gastric body involvement (47.9%) and ulceroinfiltrative morphology on endoscopy (43.8%) were common features. Regardless of the two groups, the initial endoscopic diagnosis was considered as lymphoma only in 41.7%. Compared with the primary group, fundus (P = 0.035) and regional lymph node (P < 0.001) were significantly associated with the secondary group. However, there was no significant difference in endoscopic findings including location, size, number, and morphology of lesion.

Conclusions

: Endoscopic diagnosis of gastric lymphoma is a challenge. There is no difference in endoscopic findings between the primary and secondary groups even when confirmed separately. However, when the lesion is present in the fundus, we keep in mind the possibility of secondary gastric lymphoma.

Abstract PDF PubReader ePub: We report a case of difficult endotracheal intubation in a patient with tracheobronchopathia osteochondroplastica. A 65-year-old man was scheduled to undergo ulnar nerve decompression and ganglion excisional biopsy under general anesthesia. During induction of general anesthesia, an endotracheal tube could not be advanced through the vocal cords due to resistance. A large number of nodules were identified below the vocal cords using a Glidescope® video-laryngoscopy, and fiberoptic bronchoscopy revealed irregular nodules on the surface of the entire trachea and the main bronchus below the vocal cords. Use of a small endotracheal tube was attempted and failed. a laryngeal mask airway (LMA Supreme ™) rather than further intubation was successfully used to maintain the airway.
