Although gastroesophageal damage is commonly induced by accidental drinking of a strong acid or alkali, damage due to the consumption of a vinegar beverage is not well known. We report a case of corrosive esophageal ulcer found in an adolescent consuming a vinegar drink daily. A 15-year-old male visited the emergency room presenting with hematemesis and severe epigastric pain. Multiple longitudinal ulcers, concurrent mucosal hemorrhage, and denuded mucosa were noted in the whole of the esophagus via an endoscopic examination. He had been drinking a vinegar beverage daily without sufficient dilution. The patient was treated with corticosteroid, antibiotic therapy, and mucosa protecting alginate medication and was asked to fast for a week. The follow-up endoscopy showed improvement of the esophageal injuries. Overall, continuous consumption of a vinegar beverage can result in acidic burns and destruction of the surface of the upper gastrointestinal tract. Therefore, vinegar beverages should be considered as corrosive agents.

BACKGROUND:
Angiogenesis plays an important role in determining the fat graft survival. However, clinical preconditioning techniques that target angiogenesis during fat grafting have not been established so far. Adenosine has emerged as a regulator of angiogenesis under hypoxic conditions; therefore, the aim of this study was to investigate the effects and underlying mechanisms of adenosine prefabrication on fat graft survival.
METHODS:
In the first animal study, a total of 32 mice were transplanted with fat prefabricated with vehicle (Control, N = 16) or adenosine (Adenosine, N = 16). In the second animal study, 24 mice were divided into three groups based on the type of fat graft: Control (N = 8), Adenosine (N = 8), and Axitinib (cotreatment of adenosine with axitinib, N = 8). At 1- and 4-weeks post-transplantation, grafts were evaluated by histopathological and biochemical assessment. Adenosineinduced vascular endothelial growth factor (VEGF) production and angiogenesis were determined using cell cultures.
RESULTS:
The retention volumes of fat grafts in the adenosine group were significantly increased until 4 weeks. Fat grafts from the adenosine group exhibited greater structural integrity, reduced fibrosis, and increased blood vessels. The expression levels of angiogenesis-related genes, Vegfa, Vegfr1, Vegfr2, and Vwf, were elevated in the adenosine group. Furthermore, adenosine upregulated VEGF production in preadipocytes, thereby enhancing the migration of endothelial cells. Treatment with the axitinib, VEGF receptor inhibitor, abrogated the adenosine-induced angiogenesis in the fat grafts.
CONCLUSION
Adenosine prefabrication in fat improved the graft survival by enhancing angiogenesis through the VEGF/VEGFR axis in the preadipocytes and endothelial cells. Therefore, this method may be used as a novel strategy to increase the retention rate in fat grafts.

We report a case of cardiac lymphoma in a 40-year-old man, who had a mediastinal mass which was diagnosed as sclerosing mediastinitis pathologically. The mediastinal mass caused right pulmonary arterial stenosis. The patient developed myocardial hypertrophy and echocardiography showed restrictive physiology and severely decreased left ventricle ejection fraction, 6 months later. MRI showed global left ventricular myocardial hypertrophy and diffuse late gadolinium hyperenhancement after administration of contrast material. Thus, non-ischemic cardiomyopathy was suspected on MRI. However, pathology confirmed the myocardial abnormality as lymphoma after myocardial biopsy. Because a basal part of the left ventricle and global subendocardial myocardium were not involved on contrast-enhanced delayed MRI, the MRI abnormalities could be differentiated from amyloidosis and other myocardial diseases. The peculiar non-mass forming diffuse hypertrophy pattern of cardiac lymphoma has not been known in the MRI literature.

Cryptococcus neoformans is a fungus that primarily causes opportunistic infections in immunocompromised hosts. It can also cause various infections in immunocompetent patients. Pulmonary cryptococcosis involving the lymph node is relatively rare in immunocompetent patients. In this report, a previously healthy 17-year-old girl presented with high-grade fever and persistent cough. Chest X-ray and computed tomography (CT) scan revealed an anterior mediastinal conglomerate mass that expanded to the right supraclavicular area. Ultrasound-guided gun biopsy revealed histological evidence of cryptococcosis. Immunological screening tests did not identify immunodeficiency. She recovered completely with a combination therapy of amphotericin B and flucytosine for 2 weeks, followed by fluconazole for 8 months. The characteristics of cryptococcosis involving the mediastinal lymph node and the lung should be understood, and the possibility of cryptococcosis even in immunocompetent hosts should be considered.

Most solitary gastrointestinal (GI) polyps in children are either inflammatory or hamartomatous. Solitary hyperplastic polyp, sentinel polyp and solitary adenomatous polyp have been occasionally diagnosed in adults, but very rarely reported in Korean children. We recently came across a case with adenomatous polyp in the colon, a case with hyperplastic polyp beneath the gastroesophageal junction, a case with hyperplastic polyp in the prepyloric area, and a case with sentinel polyp in the distal esophagus, which are unusual pathologic types in children. These mucosal lesions were diagnosed incidentally during elective endoscopic examinations for GI symptoms. Most polyps do not cause significant symptoms, so the diagnosis might be delayed, especially in children, in whom GI endoscopy is not commonly performed for screening purpose as in the adults.

Purpose:
Patients experience severe physical trauma every year. However, studies on survivors’ experiences after severe injury are limited. Previous studies have mainly focused on time spans of trauma treatment. This study aimed to comprehensively explore survivors’ experiences to improve the current quality of trauma treatment and highlight the importance of patient-centered care.
Materials and Methods:
Structured, face-to-face interviews with six domains were conducted on survivors aged ≥18 years who were previously hospitalized in an intensive care unit due to traumatic injuries. Self-reported questionnaires were administered for a multidimensional assessment of participants’ conditions. Transcripts of each narrative were analyzed per grounded theory.
Results:
Fourteen participants were assessed. The median injury severity score was 25.5. The median elapsed time from injury to interview was 17.3 months. The physical and psychiatric difficulties of the participants remained unresolved even after completing rehabilitation. The main theme derived from the narratives were struggle with injury, consequences, and contributing factors, with the following subthemes: 1) suffering from injury and treatment, 2) psychological adaptation to the changed self and life after the accident, 3) significant family support, 4) gratitude to medical staff despite inadequacies in the healthcare system, and 5) legal and economic issues that impede recovery.
Conclusion
Increased efforts focusing on enabling survivors of severe injury to return to society and improve their quality of life are needed, including the establishment of patient-centered care in the trauma field, extended care for the survivors’ families, multidisciplinary treatment, and the collection of quantitative post-discharge data.
