A 47-year-old man with myasthenia gravis (MG) was admitted for a lung transplant. He had bronchiolitis obliterans after allogeneic hematopoietic stem cell transplantation due to acute myeloid leukemia. MG developed after stem cell transplantation. Bilateral sequential lung transplantations and a total thymectomy were performed. The patient underwent right diaphragmatic plication simultaneously due to preoperatively diagnosed right diaphragmatic paralysis. A tracheostomy was performed and bilevel positive airway pressure (BiPAP) was applied on postoperative days 8 and 9, respectively. The patient was transferred to the general ward on postoperative day 12, successfully weaned off BiPAP on postoperative day 18, and finally discharged on postoperative day 62.

Scabies is a highly contagious skin infestation caused by the mite, Sarcoptes scabiei var. hominis. Complex responses to scabies mites in the innate, humoral, and cellular immune systems can cause skin inflammation and pruritus. Diagnosis can be challenging because scabies resembles other common skin conditions. We report the first Korean case of scabies in a hematopoietic cell transplant (HCT) recipient, initially suspected of skin graft versus host disease (GVHD). A T-cell acute lymphocytic leukemia patient underwent a sibling-matched allogeneic HCT and developed pruritus after cell engraftment. Treatment for GVHD did not improve the symptoms. He was diagnosed with scabies 30 days after the onset of symptoms.

Burkholderia cepacia, a widespread gram-negative environmental bacillus associated with nosocomial infection, is considered to be of relatively low virulence and rarely to cause invasive disease in immunocompromised patients. Nosocomial infections resulting from the use of contaminted medication, antiseptics and instruments have also been reported in otherwise healthy hosts. We experienced two cases of B. cepacia sepsis in 10 year-old male who was medicated with the anticancer drugs for the treatment of acute lymphoblastic leukemia(ALL) and in 15 day-old newborn who was examined with voiding vesicourethrography(VCUG) for the evaluation of congenital hydronephrosis. The organism isolated from serial blood culture in ALL patient and from serial blood culture and urine culture in newborn examined with VCUG. The former ALL patient improved after antibacterial medication of imipenem and the latter newborn improved after treatment with imipenem and trimethoprim-sulfamethoxazole.

Objectives : We investigated whether the components of Ailanthus altissima induced apoptotic cell death in Jurkat acute lymphoblastic leukemia (ALL) cells. Methods : Regulation of cell proliferation is a complex process involving the regulated expression and/or modification of discrete gene products, which control transition between different stages of the cell cycle. Results : Upon treatments with Ailanthus altissima, the concentration-dependent inhibitions of cell viability were observed as compared to untreated control group. The capability of Ailanthus altissima to induce apoptosis was associated with proteolytic cleavage of specific target proteins such as poly(ADP-ribose)polymerase (PARP) and beta-catenin proteins suggesting the possible involvement of caspases. Ailanthus altissima also caused apoptosis as measured by cell morphology and DNA fragmentation. Conclusions : These results indicate that the increase of apoptotic cell death by Ailanthus altissima may be due to the inhibition of cell cycle in human Jurkat lymphocytes. Conclusively, these current and further findings will provide novel approaches to understanding and treating major diseases.

Herpes zoster (HZ) is an acute infection of the unilateral sensory dermatome caused by varicella-zoster virus (VZV) and is characterized by vesicular eruption and unilateral pain along the involved dermatome. Although the pathogenesis of HZ is incompletely understood, it is thought that when cell-mediated immunity falls below a critical level, dormant VZV within cells of the sensory ganglia are allowed to replicate and infect the host with the resultant clinical presentation of HZ. It has been associated with immunosuppressed states, such as advanced age, leukemia, lymphoma, chemotherapy and/or radiation treatment. We present a case of a 62-year-old female patient with malignant lymphoma suffering herpes zoster ophthalmicus who did not respond to conventional treatment, and in whom the application of various nerve blocks and patient-controlled analgesia produced moderate pain relief. The patient died twenty days later due to cardiopulmonary failure.

Ailanthus altissima has been used to settle an upset stomach, to alleviate a fever and as an insecticide. We reported that the water extract of A. altissima induced apoptotic cell death in Jurkat T-acute Iymphoblastic leukemia cells. Here, we showed the dose-dependent inhibitions of cell viability by the extract, as measured by cell morphology. The cell cycle control genes are considered to play important roles in tumorigenesis. The purpose of the present study is also to investigate the effect of A. altissima on cell cycle progression and its molecular mechanism in the cells. The level of p21 protein was increased after treatment of the extract, whereas both Bcl-2 and Bax protein levels were not changed. These results suggest that A. altissima induces apoptotic cell death via p21-dependent signaling pathway in Jurkat cells which delete wild type p53. Gl checkpoint related gene products tested (cyclin D3, cyclin dependent kinase 4, retinoblastoma, E2Fl) were decreased in their protein levels in a dose-dependent manner after treatment of the extract Taken together, these results indicate that the increase of apoptotic cell death by A. altissima may be due to the inhibition of cell cycle in Jurkat cells.

Myelodysplastic syndromes (MDS) represent a heterogeneous group of clonal hematologic neoplasms characterized by morphologic dysplasia, aberrant hematopoiesis and peripheral blood refractory cytopenias. MDS is recognized to be associated with an increased risk of symptomatic anemia, infectious complications and bleeding diathesis, as well as a risk of progression to acute myeloid leukemia, particularly in patients with a high IPSS score. The advent of use of hematopoietic growth factors such as granulocyte colony-stimulating factor (G-CSF) and recombinant erythropoietin (EPO) has improved symptoms in MDS patients in addition to some data that suggest there might be an improvement in survival. G-CSF is an effective therapeutic option in MDS patients, and it should be considered for the management of refractory symptomatic cytopenias. G-CSF and EPO in combination can improve outcomes in appropriate MDS patients such as those with lower-risk MDS and refractory anemia with ring sideroblasts (RARS). This article reviews use of growth factors for lower-risk MDS patients, and examines the data for G-CSF, EPO and thrombopietic growth factors (TPO) that are available or being developed as therapeutic modalities for this challenging disease.

Proteasome, a multicatalytic protease complex, has been validated as a promising therapeutic target in oncology. Carfilzomib (Kyprolis$^{(R)}$), a tetrapeptide epoxyketone, irreversibly inhibits the chymotrypsin-like (CT-L) activity of the proteasome and has been recently approved for multiple myeloma treatment by FDA. A chemistry effort was initiated to discover the compounds that are reversibly inhibit the proteasome by replacing the epoxyketone moiety of carfilzomib with a variety of ketones as reversible and covalent warheads at the C-terminus. The newly synthesized compounds exhibited significant inhibitory activity against CT-L activity of the human 20S proteasome. When the compounds were tested for cancer cell viability, 14-8 was found to be most potent in inhibiting Molt-4 acute lymphoblastic leukemia cell line with a $GI_{50}$ of $4.4{\mu}M$. Cytotoxic effects of 14-8 were further evaluated by cell cycle analysis and Western blotting, demonstrating activation of apoptotic pathways.
