ABSTRACT

BACKGROUND/AIMS: We applied a back light system (BLS) with a magnifying glass to improve the ability to assess the adequacy of specimen sampling using endosonography. We conducted this study to evaluate the efficacy of the BLS in sampling of specimens by endoscopic ultrasound-guided fine needle aspiration of solid pancreatic masses. METHODS: This was a prospective, randomized, crossover, single-center clinical trial. An endosonographer evaluated adequacy on gross visual inspection and identified whitish specimen sampling sites with and without the BLS according to a randomization sequence in the first and second passes with a 25-G needle. On cytological evaluation, the presence of well-defined pancreatic ductal epithelium was evaluated by a cytopathologist who was blinded to any clinical information. RESULTS: A total of 80 consecutive patients were eligible during the study period. Adequacy was observed for 52 specimens (65%) with the BLS and 54 (68%) without the BLS (p=0.88). In assessment of specimen adequacy on gross examination, only fair agreement was observed both with and without BLS (kappa score 0.40 and 0.29, respectively). CONCLUSIONS: The BLS did not influence the ability to identify specimen sampling sites or reliable assessment of specimen site adequacy using gross visual inspection.

ABSTRACT

A 2-month-old female Holstein calf and a 5-month-old female Japanese black calf presented with gingival vascular hamartoma located in the interdental space between the second and third mandibular incisors in the right and left mandibles, respectively. On radiographic or computed tomographic images, osteolytic changes appeared within the mandibular bones adjacent to the masses. The masses were removed along with affected mandibular bone by using unilateral rostral mandibulectomy. After surgery, both cases exhibited a normal appetite and grew normally, with no cosmetic changes or recurrences. Unilateral rostral mandibulectomy can be applied for invasive gingival vascular hamartomas associated with osteolytic changes.

ABSTRACT

<p>A 50-year-old man with an extensive thoracic aortic aneurysm underwent staged surgery which consisted of preceding total aortic arch replacement with the frozen elephant trunk technique using J Graft Open Stent Graft<sup>®</sup>, followed by open thoracoabdominal aortic aneurysm repair. During the second operation, the descending aorta was cross clamped along with the preexisting stent graft, and Dacron graft was anastomosed directly to the stent graft using a running 4-0 monofilament suture. The anastomosis site was then covered with a short piece of Dacron graft identical with the stent graft in size to secure hemostasis. We herein discuss our approach in this complex case, focusing on prevention of inadvertent events such as deformation of the preexisting stent graft and unexpected bleeding.</p>

ABSTRACT

<p>Objectives: We developed versions 2 and 3 of the Biological Prognostic Score (BPS) for advanced cancer patients and confirmed the prediction accuracy. Methods: We conducted a parametric survival analysis using blood test data, performance status (PS), clinical symptoms, age, sex, and cancer type as variables for advanced cancer patients who completed or suspended cancer treatment, in the development of BPS2 and BPS3. We then prospectively compared the accuracy between BPS2/BPS3 and the Palliative Prognostic Index (PPI). Results: We developed the BPS2 and BPS3 based on the data from 589 patients in a development cohort. While the former version was calculated based on the cholinesterase, blood urea nitrogen, and white blood cell counts, the latter was calculated based on the BPS2, ECOG PS and edema. For 206 patients in a validation cohort, the overall accuracy in prediction of survival for 3 and 6 weeks using the BPS2 and BPS3 were significantly higher than those for the PPI. Conclusion: The usefulness of BPS2 and BPS3 was suggested.</p>

ABSTRACT

Objective: To develop and confirm the validity of a Biological Prognostic Score using only blood test results for prediction of prognosis in patients with advanced cancer. Methods: We conducted parametric survival time analysis using blood test results, age, sex, and primary diagnosis as independent variables, and event of death as a dependent variable, among patients in a palliative care unit (a development cohort). We then developed the Biological Prognostic Score (BPS). Thereafter, we confirmed the accuracy of the BPS and the Palliative Prognostic Index (PPI) prospectively among patients, who withdrew or withheld further curative or life-prolonging therapies, in other facilities (a validation cohort). Results: We developed the BPS, which consists of cholinesterase, blood urea nitrogen, and total iron-binding capacity, from 122 patients in a development cohort. We then examined 195 patients in a validation cohort and found that the area under the receiver operating characteristic curve for 1-9 week survival prediction was BPS=0.76-0.86 and PPI=0.69-0.73. Discussion: Our results suggest that the BPS was valid. It will be necessary to perform further examinations in multiple facilities and to explore more generalized parameters that could replace total iron-binding capacity in our BPS.

ABSTRACT

Purpose:We evaluated that the current state from which a palliative care unit receives emergency admission of cancer patients at home. Methods:We retrospectively investigated the medical records of 393 cancer patients who hospitalized in our unit between January 2013 and December 2014. The patients were shared with a group of two, schedule admission (schedule group) and emergency admission (emergency group), and it was compared with a result on discharge and with a hospitalization period. We investigated admission process, the date and time of admission, and reason for admission in emergency group. Results:The number of patients was 224 of schedule group and 169 of emergency group. The mortality rates were 81% in schedule group and 78% in emergency group (not significant). An emergency group for an average of 24.3 days was shorter for 9 days than schedule groups in a hospitalization period of dead leaving patients (p<0.05). In emergency group, admission process included 128 completed-interviews with the hospitalization, 11 incompleted-interviews before admission and 30 first visits, and 129 patients (76%) admitted within the weekday daytime. Many patients had a complaint of severe pain, appetite loss and oral absorption difficulty, and so much. Conclusions:An emergency group admitted the various processes and the much symptom. There were a lot of cases of early hospital death, but also admitted return at home, and our unit played the role of emergency admission.

ABSTRACT

<b>Purpose:</b> To investigate the indications for use of the Japanese version of the Liverpool Care Pathway (LCP), we evaluated the conditions of patients using and those not using the LCP. <b>Methods:</b> We retrospectively investigated the medical records of 71 LCP patients and 60 non-LCP patients who died in our palliative care unit between March and December 2013. <b>Results:</b> There was no significant difference in patients’ background between the LCP and non-LCP groups. For patients in the non-LCP group, sudden changes in condition were significantly more frequent and deep continuous sedation was used significantly less than in the LCP group. In the LCP group, the average duration on the LCP was 4.0 days, and the beginning criterion was met by three-point or more of all the patients. The initial assessment was achieved except for one case. In the non-LCP group, reasons for not using the LCP were a sudden change in condition (35 patients), a rapid change in medical condition (14), and a risk of falling (4). <b>Conclusions:</b> The LCP met the beginning criterion and was started at suitable time in the LCP group. The LCP is not useful for all patients; it cannot be used for a patient with sudden or rapid changes in condition, or at a risk of falling.

ABSTRACT

<b>Purpose</b>: We evaluated the significance of support for leaving the palliative care unit temporarily in end-stage terminally ill cancer patients. <b>Methods</b>: We retrospectively investigated the medical records of 27 terminally ill cancer patients who died within 15 days after leaving our palliative care unit temporarily, between January 2011 and December 2012, and distributed a questionnaire to their bereaved family. <b>Results</b>: The age of the patients ranged from 29 to 91 years. Ten patients left the unit without stay and 17 left overnight. The destination of 24 patients was their home, while three had other destinations. For 11 patients, the main purpose of leaving the unit was to finish business, and for 9, was to see their houses once again. After returning to the hospital, the comments of 15 patients were affirmative, and those of 6 were negative. Questionnaire responses were obtained from 18 persons. Families reported anxiety regarding and difficulty with adaptation to the sudden change when the patients left the unit, apparatus support, patient transfer, and patient care. <b>Conclusions</b>: It was useful for the terminally ill cancer patients and their families to receive support when leaving the palliative care unit temporarily. Strategies to cope with the sudden change at the time of leaving the unit could help families feel reassured and secure.

ABSTRACT

<b>Purpose</b>: To investigate the characteristics of sudden abdominal condition change that occur in a palliative care unit, we evaluated the association between these conditions and family acceptance at time of death. <b>Methods</b>: We retrospectively investigated the medical records of 30 terminally ill cancer patients who died of sudden abdominal condition change in our unit between January 2010 and March 2013. We focused particularly on the course of sudden change, symptom relief, explanation of the condition, and family acceptance at time of death. <b>Results</b>: The average time from onset of sudden change in abdominal condition until death was 20.6 hours and the median was 13 hours. Of the 30 total cases, 23 occurred in less than 24 hours. Frequent symptoms during the sudden change were abdominal pain in 28 patients, decreased blood pressure in 21, lowering of consciousness in 12 and disturbed behavior/excitement in 10. Impending symptoms were observed in 18 patients. For patients with good acceptance by family at time of death (21 patients), symptom relief was significantly better, frequency of disturbed behavior/excitement was significantly less, and prior specific explanation was significantly frequent, compared to the poor acceptance group (9 patients). The good acceptance group tended to be have a longer hospital stay, as well as longer time between sudden change and death. <b>Conclusions</b>: Death by sudden abdominal condition change came within 24 hours in a majority of cases. We consider that prior detailed explanation and improving symptom relief helps improve family acceptance.

ABSTRACT

<p><b>BACKGROUND</b>Interferon (IFN) can inhibit human immunodeficiency virus type 1 (HIV-1) replication in vitro and in clinic. However, IFN therapy for HIV infection was limited by its moderate antiviral efficacy and its frequent adverse effects. In the present study we evaluated the anti-HIV efficacy of a novel synthesized superior interferon α (sIFNα).</p><p><b>METHODS</b>We performed in vitro experiments with HIV-1 IIIB infected MT4 cells, and evaluated in vivo anti-HIV efficacy of sIFNα in severe combined immunodeficient (SCID) mice reconstituted with human peripheral blood leukocytes (hu-PBL-SCID mice).</p><p><b>RESULTS</b>We found that the 50% effective concentrations (EC(50)) of sIFNα against the replication of HIV-1 in MT4 cells was 0.06 ng/ml, representing stronger antiviral activity than interferon-α in vitro. In the hu-PBL-SCID mice, a dose-dependent protection pattern was observed: with 0.45 µg and 1.35 µg sIFNα daily treatments, parts of SCID mice were protected from HIV infection, whereas 2.25 µg sIFNα daily treatments resulted in a terminally complete protection.</p><p><b>CONCLUSIONS</b>sIFNα shows good anti-HIV activity both in vitro and in SCID mice, may be a promising anti-HIV agent deserving clinical investigation, especially considering the potential of IFN-α to inhibit HIV replication in patients infected with drug-resistant variants or co-infected with hepatitis C virus (HCV).</p>
