An 18-year-old woman was evaluated for a chronic productive cough and dyspnea. She was subsequently diagnosed with mediastinal non-Hodgkin lymphoma (NHL). A covered self-expandable metallic stent (SEMS) was implanted to relieve narrowing in for both main bronchi. The NHL went into complete remission after six chemotherapy cycles, but atelectasis developed in the left lower lobe 18 months after SEMS insertion. The left main bronchus was completely occluded by granulation tissue. However, the right main bronchus and intermedius bronchus were patent. Granulation tissue was observed adjacent to the SEMS. The granulation tissue and the SEMS were excised, and a silicone stent was successfully implanted using a rigid bronchoscope. SEMS is advantageous owing to its easy implantation, but there are considerable potential complications such as severe reactive granulation, stent rupture, and ventilation failure in serious cases. Therefore, SEMS should be avoided whenever possible in patients with benign airway disease. This case highlights that SEMS implantation should be avoided even in malignant airway obstruction cases if the underlying malignancy is curable.

On 7 December 2007, the Hebei Spirit ran aground near Taean and released approximately 10,900 tons of oil into the sea. Crude oil on the coastal areas and fumes in the air increased the number of health problems among the local population. We report a case of respiratory failure after the oil spill clean-up work. A 66-year-old female was admitted to hospital with cough, sputum, and dyspnea of 1-month duration after the oil spill clean-up. She was diagnosed with community-acquired pneumonia and treated with empirical antibiotics. However, she had progressive respiratory failure without identification of the pathogen. Respiratory failure due to chronic inhalation of hydrocarbons from the crude oil spill clean-up was suspected. After mechanical ventilation care, she recovered from respiratory failure and was discharged. We report a case of severe respiratory toxic effects after an oil spill clean-up. We concluded that long-term hydrocarbon inhalation during the oil spill clean-up may have induced respiratory failure in this case.

Purpose: Glehnia littoralis has been used to treat ischemic stroke, phlegm, cough, systemic paralysis, antipyretics and neuralgia. The pharmacological mechanisms of Glehnia littoralis include calcium channel block, coumarin derivatives, anticoagulation, anti-convulsive effect, as well as anti-oxidant and anti-inflammatory effects. Alpha-amanitin (${\alpha}$-amanitin) is a major toxin from extremely poisonous Amanita fungi. Oxidative stress, which may contribute to severe hepatotoxicity was induced by ${\alpha}$-amanitin. The aim of this study was to investigate whether Glehnia littoralis ethyl acetate extract (GLEA) has the protective antioxidant effects on ${\alpha}$-amanitin -induced hepatotoxicity. Methods: Human hepatoma cell line HepG2 cells were pretreated in the presence or absence of GLEA (50, 100 and $200{\mu}g/ml$) for 4 hours, then exposed to $60{\mu}mol/L$ of${\alpha}$-amanitin for an additional 4 hours. Cell viability was evaluated using the MTT method. AST, ALT, and LDH production in a culture medium and intracellular MDA, GSH, and SOD levels were determined. Results: GLEA (50, 100 and $200{\mu}g/ml$) significantly increased the relative cell viability by 7.11, 9.87, and 14.39%, respectively, and reduced the level of ALT by 10.39%, 34.27%, and 52.14%, AST by 9.89%, 15.16%, and 32.84%, as well as LDH by 15.86%, 22.98%, and 24.32% in culture medium, respectively. GLEA could also remarkably decrease the level of MDA and increase the content of GSH and SOD in the HepG2 cells. Conclusion: In the in vitro model, Glehnia littoralis was effective in limiting hepatic injury after ${\alpha}$-amanitin poisoning. Its antioxidant effect is attenuated by antidotal therapy.
Rectus sheath hematoma (RSH) is a rare condition caused by hemorrhage into the rectus sheath. It is usually associated with severe cough, abdominal surgery, coagulopathy, and anticoagulation treatment. RSH can be difficult to diagnose and can be misdiagnosed as acute appendicitis, as diverticulitis, or as an ovarian mass. Although RSH usually presents as a benign condition, it can be life threatening, especially in the critically-ill patient. Here, we report a case of fatal RSH due to hypovolemic shock in a critically-ill 73-year-old woman, who had received heparin treatment due to acute myocardial infarction in the intensive care unit and who had been successfully treated by conservative management.

Pulmonary hamartoma is a common benign tumor of the lung, but endobronchial hamartoma is a rare tumor. Although bronchoscopic rcemoval or removal by bronchotomy or sleeve resection with preservation of the lung may be possible, when irreversible lung damage has occurred because of chronic obstruction and pneumonitis, pulmonary resection may be indicated. We herein report a case of endobronchial hamartoma which was treated by left upper lobectomy. A 42-year-old female with 3-week history of cough and left chest pain visited our hospital. Bronchoscopy showed total occlusion of the orifice of the left upper lobe bronchus by a lobulated endobronchial tumor and bronchoscopic biopsy was failed due to bleeding. A left upper lobectomy was performed because of severe consolidation of the left upper lobe by chronic obstruction. The patient was discharged on postoperative 14th day.
Background: As the coronavirus disease 2019 (COVID-19) outbreak continues to evolve, it is crucially important for pediatricians to be aware of the differences in demographic and clinical features between COVID-19 and influenza A and B infections. Purpose: This study analyzed and compared the clinical features and laboratory findings of COVID-19 and influenza A and B infections in children. Methods: This retrospective study evaluated the medical data of 206 pediatric COVID-19 and 411 pediatric seasonal influenza A or B patients. Results: COVID-19 patients were older than seasonal influenza patients (median [interquartile range], 7.75 [2-14] years vs. 4 [2-6] years). The frequency of fever and cough in COVID-19 patients was lower than that of seasonal influenza patients (80.6% vs. 94.4%, P<0.001 and 22.8 % vs. 71.5%, P<0.001, respectively). Ageusia (4.9%) and anosmia (3.4%) were present in only COVID-19 patients. Leukopenia, lymphopenia, and thrombocytopenia were encountered more frequently in influenza patients than in COVID-19 patients (22.1% vs. 8.5%, P=0.029; 17.6% vs. 5.6%, P=0.013; and 13.2% vs. 5.6%, P=0.048, respectively). Both groups showed significantly elevated monocyte levels in the complete blood count (70.4% vs. 69.9%, P=0.511). Major chest x-ray findings in COVID-19 patients included mild diffuse ground-glass opacity and right lower lobe infiltrates. There were no statistically significant intergroup differences in hospitalization or mortality rates; however, the intensive care unit admission rate was higher among COVID-19 patients (2.4% vs. 0.5%, P=0.045). Conclusion: In this study, pediatric COVID-19 patients showed a wide range of clinical presentations ranging from asymptomatic/mild to severe illness. We found no intergroup differences in hospitalization rates, oxygen requirements, or hospital length of stay; however, the intensive care unit admission rate was higher among COVID-19 patients.

Background: Viral load and shedding duration are highly associated with the transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. However, limited studies have reported on viral load or shedding in children and adolescents infected with sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Purpose: This study aimed to investigate the natural course of viral load in asymptomatic or mild pediatric cases. Methods: Thirty-one children (<18 years) with confirmed SARS-CoV-2 infection were hospitalized and enrolled in this study. Viral loads were evaluated in nasopharyngeal swab samples using real-time reverse transcription polymerase chain reaction (E, RdRp, N genes). cycle threshold (Ct) values were measured when patients met the clinical criteria to be released from quarantine. Results: The mean age of the patients was 9.8 years, 18 (58%) had mild disease, and 13 (42%) were asymptomatic. Most children were infected by adult family members, most commonly by their mothers. The most common symptoms were fever and sputum (26%), followed by cough and runny nose. Nine patients (29%) had a high or intermediate viral load (Ct value≤30) when they had no clinical symptoms. Viral load showed no difference between symptomatic and asymptomatic patients. Viral rebounds were found in 15 cases (48%), which contributed to prolonged viral detection. The mean duration of viral detection was 25.6 days. Viral loads were significantly lower in patients with viral rebounds than in those with no rebound (E, P=0.003; RdRp, P=0.01; N, P=0.02). Conclusion: Our study showed that many pediatric patients with coronavirus disease 2019 (COVID-19) experienced viral rebound and showed viral detection for more than 3 weeks. Further studies are needed to investigate the relationship between viral rebound and infectiousness in COVID-19.

Purpose: Children with nephrotic syndrome may experience disease relapse or aggravation triggered by various viral infections. Limited studies on the clinical implications of the coronavirus disease 2019 (COVID-19) pandemic in children with nephrotic syndrome have been published worldwide. Therefore, this study aimed to investigate the effects of COVID-19 on the clinical course of nephrotic syndrome in children. Methods: The medical records of 59 patients with idiopathic nephrotic syndrome who visited our hospital between February and June 2022 were retrospectively analyzed. Results: Twenty of the total 59 patients with nephrotic syndrome were diagnosed with COVID-19 during the study period. The mean age at the time of the diagnosis of nephrotic syndrome and COVID-19 in all 20 patients was 4.6±3.5 and 8.9±3.9 years, respectively. Three patients (15%) were diagnosed with nephrotic syndrome relapse during COVID-19 and the relapse rate was similar to them without COVID-19 (20.5%, 8/39 patients). At the time of the COVID-19 diagnosis, fever (85%) and cough (40%) were the most common symptoms. After the diagnosis of COVID-19, all patients showed improvement with symptomatic treatment, including antipyretic analgesics and cold medicine. None of the critical patients required hospitalization or oral antiviral medications. Conclusions: Despite the use of immunosuppressants, the clinical manifestations of COVID-19 in children with nephrotic syndrome were not severe and are expected to be similar to that in the general population. The relapse rate of nephrotic syndrome in children with COVID-19 was also not different from them without COVID-19.
Objectives This study aims to identify differences in clinical manifestations of COVID-19 between different Sasang constitution. Methods Subjects were recruited from August 29, 2022, to July 11, 2023. COVID-19 clinical symptoms were self-reported via questionnaires. Sasang constitutional diagnosis was performed using the K-PRISM, and Sasang constitutional specialist. Results A total of 66 subjects were recruited for the study, and the Sasang constitutional distribution of the subjects was 19 soyangin, 25 taeeumin, and 22 soeumin. For most of the COVID-19 clinical manifestations, the study found that soyangin experienced symptoms at a higher rate than other constitutions. Among the symptoms observed in the study, sore throat, pantalgia, and cough were severe in all subjects regardless of constitution. Soeumin was more likely to experience abdominal pain, chest pain, and diarrhea, while soyangin was more likely to experience chest pain, nausea/vomiting, diarrhea, and cutaneous symptoms compared to other constitutions. Taeeumin had more sputm, nasal congestion, and skin symptoms, but fewer digestive symptoms. There were differences in the onset and duration of symptoms by constitution. Conclusions This study is an important contribution to our understanding of the differences in response to the COVID-19 virus among different Sasang constitutions. Symptomatic differences between constitutions may have important implications for prevention and treatment strategies for infectious diseases, and personalized treatment and management based on these differences may be needed in the future.

Tuberculosis is an adverse event in patients with Crohn's disease receiving anti-tumor necrosis factor (TNF) therapy. However, tuberculosis presenting as a bronchoesophageal fistula (BEF) is rare. We report a case of tuberculosis and BEF in a patient with Crohn's disease who received anti-TNF therapy. A 33-year-old Korean woman developed fever and cough 2 months after initiation of anti-TNF therapy. And the symptoms persisted for 1 months, so she visited the emergency room. Chest computed tomography was performed upon visiting the emergency room, which showed BEF with aspiration pneumonia. Esophagogastroduodenoscopy with biopsy and endobronchial ultrasound with transbronchial needle aspiration confirmed that the cause of BEF was tuberculosis. Anti-tuberculosis medications were administered, and esophageal stent insertion through endoscopy was performed to manage the BEF. However, the patient's condition did not improve; therefore, fistulectomy with primary closure was performed. After fistulectomy, the anastomosis site healing was delayed due to severe inflammation, a second esophageal stent and gastrostomy tube were inserted. Nine months after the diagnosis, the fistula disappeared without recurrence, and the esophageal stent and gastrostomy tube were removed.
