Eriocaulon sieboldianum (ES) is used in traditional oriental medicine for various medicinal purposes including headache, toothache, and inflammation. However, the anti-cancer effect of the ES is still not fully understood. In the present study, the human leukemia cell line HL-60 was used to characterize the apoptotic effects of ES. ES induced cytotoxicity of HL-60 cells in a dose- and time-dependent manner. ES induced the generation of reactive oxygen species, and the release of cytochrome c in a dose-dependent manner. In addition, we showed that ES-induced apoptosis was accompanied by activation of caspase-3. Taken together, our results demonstrate that ES possesses anti-cancer activity in HL-60 cells.

Transfusion related acute lung injury (TRALI) is a serious, potentially life-threatening complication of transfusion therapy that is sometimes under diagnosed and under reported. Patients with TRALI present with dyspnea/respiratory distress and fever. The symptoms, signs and chest radiological findings in TRALI are similar to transfusion associated circulatory overload, which makes it is difficult to distinguish it from circulatory overload. Although the mortality rate in cases of TRALI is relatively low, TRALI is the third most common cause of fatal transfusion reactions next to ABO blood type incompatibility and hepatitis. Mild-to-moderate cases of TRALI may be misdiagnosed as volume overload. Recently, we encountered two cases where the patients suffered from dyspnea and fever after a transfusion. and review of the relevant literature.

Nocardia farcinia, an aerobic, gram-positive bacilli actinomycetes of the genus Nocardia, is an uncommon pathogen found in humans. The most common Nocardia infection sites are the lung, central nervous system, and skin. Even though hematogenous dissemination can occur, isolation of the organism from blood cultures is very rare. We report a case of Nocardia infection that was isolated on blood cultures. A 59-year-old male with a medical history that includes a liver transplantation 6-years prior due to hepatocellular carcinoma secondary to chronic hepatitis B, developed pneumonia and was transferred to Severance Hospital. At the time of admission, the patient's initial exam showed hypothermia, tachypnea, and hypotension. His chest radiograph showed severe pneumonia and a large abscess on left upper lobe. Under the presumptive diagnosis of bacterial pneumonia or other opportunistic infection, we started broad spectrum antibiotics. However, he developed Nocardia sepsis, rapidly deteriorated, and subsequently died.

Invasive pulmonary aspergillosis (IPA) is rarely reported in patients who have normal immune function. Recently, IPA risk was reported in nonimmunocompromised hosts, such as patients with chronic obstructive pulmonary disease and critically ill patients in intensive care units. Moreover, influenza infection is also believed to be associated with IPA among immunocompetent patients. However, most reports on IPA with influenza A infection, including pandemic influenza H1N1, and IPA associated with influenza B infection were scarcely reported. Here, we report probable IPA with a fatal clinical course in an immunocompetent patient with influenza B infection. We demonstrate IPA as a possible complication in immunocompetent patients with influenza B infection. Early clinical suspicion of IPA and timely antifungal therapy are required for better outcomes in such cases.

Central diabetes insipidus (DI) is a syndrome characterized by thirst, polydipsia and polyuria. Langerhans cell histiocytosis is one of the etiologies of DI. Recently we experienced a central DI associated with Langerhans cell histiocytosis. The 44 years old female patient complained right hip pain, polydipsia and polyuria. We carried out water deprivation test. After vasopressin injection, urine osmotic pressure was increased from 109 mOsmol/kg to 327 mOsmol/kg (300%). Brain MRI showed a thickened pituitary stalk and air bubble like lesions sized with 5cm, 7cm was shown on fifth L-spine and right hip bone at hip bone CT. CT guided biopsy revealed abnormal histiocytes proliferation and abundant lymphocytes. The final diagnosis was central DI associated with systemic Langerhans cell histiocytosis invading hip bone, L-spine and pituitary stalk. Desmopressin and etoposide chemotherapy were performed to the patient.
