The significance of the measurement of anti-p53 antibodies in serum remains undisclosed. The aim of this study was to assess anti-p53 antibodies in the serum of patients with breast cancer, and correlate these results with various clinicopathologic parameters.
The aim of this paper is to reveal the causes of death and to verify sudden death of Parkinson's disease (PD) in an autopsy study. We reviewed the clinical data and the causes of death in 16 PD patients who had postmortem examinations. Prior to autopsy, nine patients died of known causes: five patients died of aspiration pneumonia, two of myocardial infarction, one of asphyxia, and one of dilated cardiomyopathy. Autopsy confirmed that the putative causes of death were compatible with the pathological ones. The remaining seven patients died suddenly of unknown causes. Autopsy revealed that the causes of death were asphyxia in two patients and perforation of a duodenal ulcer in one patient. Autopsy did not determine the causes of unknown death in the remaining four patients. Consequently, autopsy revealed that eight patients died of swallowing problems such as aspiration pneumonia and asphyxia, four of sudden death, three of cardiac problems, and one of a gastrointestinal problem. Although there was a bias that all patients had a postmortem examination, our study revealed that several PD patients died of sudden death without any satisfactory causes of death determined even by autopsy. Therefore, we propose that a non-negligible number of PD patients die of sudden death.
Prostate-specific antigen screening has significantly increased the percentage of men who are diagnosed with low-risk prostate cancer. All men undergoing retropubic radical prostatectomy for primary treatment of prostate cancer from April 2004 to September 2010 in our hospital were examined in order to determine whether active surveillance criteria could be applied to Japanese men. From pathological data of prostate biopsies, whether these men met five published criteria for active surveillance (Johns Hopkins Medical Institution, Prostate Cancer Research International: Active Surveillance Study, University of California, San Francisco, Toronto and Kakehi criteria) was evaluated. Men who met any of the criteria had a statistically significant lower extracapsular extension rate and organ-confinement rate. From the view of the possibility of Gleason upgrading and organ-confinement rate, the Johns Hopkins Medical Institution and Prostate Cancer Research International: Active Surveillance Study criteria showed to be appropriate for Japanese patients. However, the present study had limitations of selection bias and a limited number of cases.
A 50-year-old woman was admitted because of chest pain and lumbago. A chest X-ray film showed a 4-cm mass in the left lower lung field. Computed tomography scans revealed a nodule with spicule formation in the left lower lobe, and therefore we strongly suspected lung cancer. Fiberoptic bronchoscopy yielded a diagnosis of adenocarcinoma. However, since she had metrorrhagia we performed an endometrial biopsy. Histologically, the endometrium was similar to the lung lesion, with positive staining for thyroid transcription factor-1 (TTF-1), and lung cancer with endometrial metastasis was therefore diagnosed. Although lung cancer with endometrial metastasis is rare, it should be included in the differential diagnosis in patients with gynecological symptoms such as metrorrhagia.
The prognosis of metastatic or recurrent gastrointestinal stromal tumors (GISTs) accompanied by multiple hepatic metastases and peritoneal dissemination is very poor. We encountered a case of stage IV small intestinal GIST with multiple hepatic metastases and peritoneal dissemination that were observed after resection of the primary lesion. Multidisciplinary treatments were performed over time, including hepatic resection, radiotherapy, imatinib therapy, sunitinib therapy, and transcatheter arterial chemoembolization, and the disease had been brought under control following resection of a primary lesion 14 years ago. The patient was a 49-year-old woman diagnosed with hemorrhagic stool in July 1998, when a computed tomography scan revealed an 8-cm-diameter tumor in her small bowel. Partial resection of her small bowel was performed and the pathological diagnosis was a high-risk GIST showing 15 mitoses per 50 high power fields. Several metastases developed in the S4 and S5 segments of the patients liver 3 years after resection of the primary lesion, and a central two-segmental resection of the liver was performed. Furthermore, 1 year after this procedure, peritoneal dissemination developed near the pancreas, for which radiotherapy was performed. Four months later, the patient again developed multiple liver metastases and was started on treatment with 400 mg imatinib per day, achieving a partial response(PR). Five years and 6 months after imatinib initiation, resistance emerged in one of the liver metastases. The patient was switched to sunitinib(50 mg per day), but was diagnosed with progressive disease at the end of the second course and the procedure was discontinued. Treatment with 400 mg of imatinib per day was resumed, and transcatheter arterial chemoembolization was performed twice over a 17-month period for the resistant hepatic region and a PR was achieved each time. We were able to maintain a PR in this patient; other metastases indicated the effectiveness of imatinib therapy. Therefore, a multidisciplinary team approach can be effective in achieving long-term disease control in patients with metastatic or recurrent GIST.
We report a middle-aged Japanese man who had a past history of malignant lymphoma with tubulointerstitial nephritis (TIN) presenting a high serum immunoglobulin G4 (IgG4) concentration and bilateral kidney enlargement and swelling of many lymph nodes. Although lymph node biopsy was not evident of a recurrence of lymphoma, kidney biopsy showed prominent infiltration of IgG4-positive plasma cells in a tubulointerstitial lesion but not in glomeruli. We made a diagnosis of IgG4-related TIN and lymphadenopathy; administration of oral prednisolone improved his physical and laboratory parameters. This is the first report of a case of IgG4-related TIN and lymphadenopathy after therapy for malignant lymphoma.

What is Visualize?
JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.
How does it work?
We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.
Video X seems to be unrelated to Abstract Y...
In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
