Background/AimsEosinophilia has numerous diverse causes, and in many patients, it is not possible to establish the cause of eosinophilia. Recently, toxocariasis was introduced as one cause of eosinophilia. The aims of this study were to evaluate the prevalence of toxocariasis and the clinical impact of albendazole treatment for toxocariasis in patients suspected of eosinophilia of unknown origin.MethodsWe performed a retrospective chart review. After evaluation of cause of eosinophilia, the patients suspected of eosinophilia of unknown origin performed immunoglobulin G antibody specific assay for the Toxocara canis larval antigen by enzyme-linked immunosorbent assay.ResultsThis study evaluated 113 patients, 69 patients (61%) were suspected of eosinophilia of unknown origin. Among these 69 patients, the frequency of T. canis infection was very high (45 patients, 65.2%), and albendazole treatment for 45 eosinophilia with toxocariasis was highly effective for a cure of eosinophilia than no albendazole group regardless of steroid (82.3%, p = 0.007). Furthermore, among the nonsteroid treated small group (19 patients), albendazole treatment for eosinophilia were more effective than no albendazole group, too (83.3% vs. 28.6 %, p = 0.045).ConclusionsThe prevalence of toxocariasis was high among patients suspected of eosinophilia of unknown origin; therefore, evaluation for T. canis infection is recommended for patients with eosinophilia of unknown origin. Furthermore, for patients suspected of eosinophilia of unknown origin who have positive results for T. canis, albendazole treatment may be considered a valuable treatment option.

Objective: The purpose of this study was to investigate the quality of life among cancer survivors compared with individuals without a history of cancer (noncancer controls) using the Korea National Health and Nutrition Examination Survey. Methods: The study subjects were 783 adult cancer survivors and 36 456 noncancer controls who participated in the third, fourth and fifth Korea National Health and Nutrition Examination Survey. Demographic factors, health-related behavior, clinical characteristics and healthrelated quality of life were assessed with self-reported questionnaires. The EuroQoL5Dimension was used to evaluate health-related quality of life. Descriptive statistics and multiple regression analysis were used to compare health-related quality of life between cancer survivors and noncancer controls. Results: About 67% were women and the mean age of the cancer survivors was 60.9 + 12.4 years. About 52% of survivors were diagnosed with cancer between 45 and 64 years, and more than half of cancer survivors were diagnosed 5 years or less before the interview. The pain/discomfort dimension was the highest reported problem: 43.6% for cancer survivors. The proportion of any reported problem was significantly higher among cancer survivors compared with noncancer controls in terms of mobility (adjusted odds ratio (aOR), 1.56, 95% confidence interval, 1.24 -1.97), usual activities (aOR, 1.45, 95% confidence interval, 1.11 -1.89), pain/ discomfort (aOR, 1.26, 95% confidence interval, 1.04 -1.52) and anxiety/depression (aOR, 1.61, 95% confidence interval, 1.29 -2.01). Conclusions: Cancer survivors had a significantly lower quality of life compared with noncancer controls. The pain/discomfort dimension was the highest reported problem in cancer survivors.

BackgroundMucormycosis is a rare and life-threatening invasive fungal infection. Pulmonary mucormycosis commonly occurs in patients with severe neutropenia. Typically, pulmonary mucormycosis causes tissue necrosis resulting from angioinvasion and subsequent thrombosis, so most cases can occur with necrotizing pneumonia and/or hemoptysis. Some complex cases may invade adjacent organs, such as the mediastinum, pericardium, and chest wall. However, to the best our knowledge there is little known regarding bronchoesophageal fistula due to pulmonary mucormycosis after induction chemotherapy for acute myeloid leukemia. We present a case report about this unusual presentation.Case presentationA 51-year-old Korean man was diagnosed as having acute myeloid leukemia and received induction chemotherapy. After prolonged severe neutropenia, he complained of coughing with aspiration. Imaging showed a bronchoesophageal fistula with extensive necrotizing pneumonia in the middle and lower lobes of his right lung. Bronchoscopy showed near total tissue necrosis in the middle lobe of his right lung, creating an orifice. A bronchial scope was passed through and was able to be connected with his esophagus; a bronchial wall biopsy was performed. Esophagoscopy revealed a large linear defect of his esophageal wall 30 cm from the incision that may have connected with the bronchus. A bronchial biopsy showed typical hyphae with necrotic tissue, indicating pulmonary mucormycosis. He was given amphotericin B, and a wide excision of lung and esophagus was planned. However, he suddenly died due to massive hemoptysis.ConclusionHere we present an extremely rare case of bronchoesophageal fistula with severe necrotizing pneumonia due to pulmonary mucormycosis.
