PURPOSE: The purpose of this study was to assess pain, sleep disturbance, fatigue, and the quality of life and to identify the impact of pain, sleep disturbance and fatigue on the quality of life in patients with pancreatic cancer undergoing chemotherapy. METHODS: Data were collected from June to July, 2010. Participants were recruited from Y university hospital in Seoul. Research instruments included numeric rating scale for pain, Functional Assessment Chronic Illness Therapy-Functional Well-Being (FACIT-FWB): General Factor 5 (GF5) for sleep disturbance, Functional Assessment of Cancer Therapy-General (FACT-G) for quality of life, and FACT-Fatigue for fatigue. RESULTS: The quality of life for cancer patients had a significant relationship with pain, sleep disturbance, and fatigue. The significant factors influencing quality of life were pain, sleep disturbance, and fatigue that explained 52.6% of the variance. CONCLUSION: Patients with pancreatic cancer undergoing chemotherapy experienced pain, fatigue, and sleep disturbance which led to a negative effect on quality of life. The results suggest that intervention program to improve quality of life could reduce pain, fatigue, and sleep disturbance of pancreatic cancer patients undergoing chemotherapy.

PURPOSE: This study was conducted to test whether sleep disturbance mediates the effect of pain on fatigue, whether fatigue mediates the effect of pain on depression, and whether fatigue mediates the effect of sleep disturbance on depression. METHODS: This study was conducted from September 12th to December 20th, 2011. One hundred eighty-eight breast cancer patients were recruited from D city and S city in Korea. The instruments used in this study were the pain, sleep disturbance, fatigue, and depression scales. Data were analyzed using descriptive statistics, Pearson correlation coefficients, and mediation pathway with the SPSS 12.0 and AMOS 20.0 programs. RESULTS: There was correlation among pain, fatigue, sleep disturbance, and depression. Mediation analyses indicated that pain influences fatigue. sleep disturbance, and depression directly as well as indirectly. Sleep disturbance influences fatigue and depression directly, also fatigue influences depression directly. But sleep disturbance had no direct effect on depression. CONCLUSION: Significant correlations among the four symptoms supported the existence of the symptom cluster. Effects of pain on fatigue was partially mediated by sleep disturbance, also effects of pain on depression was partially mediated by fatigue. However, the effects of sleep disturbance on depression was fully mediated by fatigue.

Background: Due to the importance of the cold chain related to vaccine transportation, it is necessary to establish a blood cold chain operation strategy by checking the status of blood transportation from blood donation to transfusion. Methods: The blood transportation system and blood storage facilities were checked by inspecting the Korean Red Cross (KRC) Blood Centers and its affiliated supplier and Hanmaeum Blood Center. The status of the cold chain was evaluated through an interview with the quality control manager or blood supply team leader. For the hospital, the status was investigated from the perspective of the 30-min rule. A questionnaire survey was conducted for medical technicians and nurses working at the hospital. Results: Data on temperature during transport of blood components were computerized, and all standards were met. A nationwide network that could supply blood from the blood supply center to the hospitals within 2 hours was established. The frequency of temperature monitoring in the blood transport box and constant temperature check in the transport box during long-distance transport were evaluated. Conclusion This study confirmed that blood storage and transportation in Korea complied with the cold chain standards of high-income countries or higher. The evaluation of the cold chain is a constantly evolving process requiring continuous attention. When standards for storage and transportation of blood products are established, strict regulations and examinations will be required.

There are some clinical evidences that hepatitis B virus(HBV) infection may cause IgA nephropathy. To evaluate clinical significances and pathogenetic roles of HBV infection in patients with IgA nephropathy, we studied that varius clinical and lab- oratory findings in 172 patients with IgA nephrop-athy as serum hepatitis B surface antigen (HBsAg) positive (19 cases) and negative group (153 cases). The result was as following: 1) The incidence of positive serum HRsAg was 11.0%(19/172 cases) in patients with IgA nephropathy and it was higher than that of the randomized age-sex matched general population(4.1%) but has no significance statistically. 2) There was no significant differences in incidence of hypertension, serum levels of IgA, C3, SGOT, SGFf between HBsAg postive and negative group. 3) The cases of nephrotic range proteinuria (3.5g/ day) was more prevalent in HBsAg positive group (31.6%) than that in negative group(7.2%). significantly (p<0.05). 4) The cases of impaired renal function (serum creatinine more than 1.4mg/dL) were more frequent in HBsAg positive group (42.19%) than that in neg-ative group (13.1%) significantly(p<0.05).

Leukocytoclastic vasculitis (LV) is a systemic inflammatory disorder involving the small vessels. The exact cause of LV remains unknown, yet malignancy has been considered as a causative factor for LV. We experienced a 60-year-old male with purpura on his extremities. Computed tomography of the chest showed a mass lesion that was suspected to be a non-small-cell lung cancer and the biopsy revealed an adenosquamous carcinoma. There has been no report of LV associated with adenosquamous carcinoma of the lung in Korea. Thus, we report here on this case along with a review of the relevant articles.

BACKGROUND: Autologous peripheral blood-stem cell transplantation (autoPBSCT) is the treatment of choice for hematologic malignancy, because the technique requires neither general anesthesia nor surgical intervention, amongst many other advantages. Despite these benefits, the risk of hematologic malignancy, as well as the effect of patient age and sex on the prediction of successful collection of autoPBSCT are still unclear. The purpose of this study was to examine whether the hematologic diagnosis of the disease, and age or sex affect the mobilization of CD34+ cells and mononuclear cells. METHODS: We retrospectively investigated 30 (6 multiple myeloma, 11 diffuse large B-cell lymphoma, 8 acute myeloid leukemia, 2 acute lymphoid leukemia, and 3 T-cell lymphoma) patients who underwent autoPBSCT between 2008 and 2011 at Daegu Catholic University Hospital. RESULTS: Patients with multiple myeloma had the highest average of both mononuclear cell (MNC) (2.07+/-0.67x10(8) cells/kg) and CD34+ cell (1.28+/-0.58x10(6) cells/kg) counts. Patients with T-cell lymphoma had both the lowest MNC (1.23+/-0.49x10(8) cells/kg) and CD34+ cell (0.20+/-0.6x10(6) cells/kg) counts. Male patients showed greater collected CD34+ cell counts (0.96+/-1.38x10(6) cells/kg) and MNC counts (1.71+/-0.76x10(8) cells/kg) than the female patients. Patients under the age of 44 had higher collected CD34+ cell counts (0.96+/-1.37x10(6) cells/kg) but lower counts of MNC (1.49+/-0.74x10(8) cells/kg). CONCLUSIONS: The collected MNC and CD34+ cell counts varied between the types of malignancies, and with respect to sex and age. However, only collected MNC counts were significantly different (P<0.05) among the different types of malignancies.
