Hide Abstract
For the preparation of pandemic influenza, Japans government requested to set up a high-fever consultation center at each prefectural and city government. During the initial period of pandemic influenza A (H1N1) outbreak in Japan, high-fever consultation centers received a great number of calls. The effectiveness of this system, however, has not been fully evaluated. This study reports the result of a qualitative study, which explored officers who provided the high-fever consultation center during influenza outbreak.

Show Abstract
Hide Abstract
We describe a high-speed long-depth range optical frequency domain imaging (OFDI) system employing a long-coherence length tunable source and demonstrate dynamic full-range imaging of the anterior segment of the eye including from the cornea surface to the posterior capsule of the crystalline lens with a depth range of 12 mm without removing complex conjugate image ambiguity. The tunable source spanned from 1260 to 1360 nm with an average output power of 15.8 mW. The fast A-scan rate of 20,000 per second provided dynamic OFDI and dependence of the whole anterior segment change on time following abrupt relaxation from the accommodated to the relaxed status, which was measured for a healthy eye and that with an intraocular lens.

Hide Abstract
An 80-year-old man was admitted to our hospital because of exacerbation of preexisting chronic kidney disease (CKD). On admission, he showed elevated levels of serum creatinine (6.37 mg/dL) and corrected calcium (13.7 mg/dL). Although the serum levels of intact parathyroid hormone (I-PTH) and parathyroid hormone-related peptide(PTITH-rP)were low, the serum 1,25-dihydroxyvitamin D3 (1,25 (OH)2D3)levels were high. Computed tomography (CT) revealed ascites, and the ascitic fluid was exudative and serous with predominance of lymphocytes. The levels of adenosine deaminase (ADA) in the ascitic fluid were also elevated, and the results of QuantiFERON-TB2G (QFT-2G)assay were positive, indicating tuberculous peritonitits. Ascites resolved rapidly after initiation of the antituberculosis therapy. The elevated levels of serum calcium and 1,25 (OH) 2D3 returned to below-normal levels; however, serum i-PTH levels increased from 8.9 pg/ mL to 432 pg/mL. Diagnosis of extrapulmonary tuberculosis is often difficult in CKD patients. CKD patients show abnormal vitamin D activation, so these patients usually have low levels of serum 1,25(OH)2D3. On the other hand, in our patient, 1,25(OH)2D3 was extrarenally produced from tuberculous granuloma and therefore, he showed high levels of serum 1,25(OH)2D3 and correspondingly, low levels of serum i-PTH. We observed that the ratio of 1,25 (OH) 2D3:i-PTH decreased due to antituberculosis therapy. This ratio facilitated the diagnosis and evaluation of treatment for this condition.

Hide Abstract
Treatment with cyclophosphamide and steroids for idiopathic membranous nephropathy (IMN) is effective in Caucasian patients, but the cumulative cyclophosphamide dosage exceeds 10 g and includes steroid pulse therapy. Adverse effects and difficulties with repeating treatment are major limitations. We studied the long-term outcomes of low-dose cyclophosphamide and prednisolone therapy in Japanese patients, who were thought to have relatively benign IMN compared with Caucasian patients.

Hide Abstract
We encountered a rare case of lymphocytic interstitial pneumonia (LIP) complicated with primary Sjögrens syndrome (SjS), followed by chest CT scanning for a long period of time. A 54-year-old man with hemoptysis was admitted to our hospital in December, 2001. A diagnosis of SjS was made based on elevation of anti-SS-B/La antibody titer in serum in combination with diagnosis of keratoconjunctivitis sicca and xerostomia on a Schirmer test and a lip biopsy, respectively. Subsequent histopathological diagnosis by open lung biopsy showed LIP. Chest CT in September, 1995 at previous hospital revealed ground-glassed opacity (GGO), small nodules, thickened bronchovascular bundles and cyst formation in lungs. Chest CT was performed every year until 2008, when remarkable progression from thickened bronchovascular bundles accompanied by nodular opacities to an air-space consolidation in the right lower lobe was observed. Also, appearance of cyst formation in the right middle lobe, nodular lesions and GGO in the left lower lobe were noticed. Although the nodular opacities and GGO improved after an administration of corticosteroid (PSL 0.5 mg/kg/day), little improvement in the consolidations and cyst formation was demonstrated. In conclusion, it was suggested that differences among CT findings of LIP may be important for evaluating of efficacy of treatment by steroid agents for LIP associated with SjS.

Show Abstract
Hide Abstract
We analyzed the efficacy of both the Streptococcus pneumoniae urine antigen test as a quick diagnostic tool and the administration of high-dose penicillin in response to a positive S. pneumoniae urine antigen test. We conducted a retrospective analysis of 48 cases of pneumococcal pneumonia, in which the patients were treated with high-dose penicillin. All the cases were diagnosed by a positive urine antigen test. Treatment with high-dose penicillin was effective in 43 of the 48 patients. This treatment was also effective in 12 of 16 culture-confirmed cases with low susceptibility to penicillin. Eleven patients who were positive for the S. pneumoniae urine antigen test but culture-negative showed clinical improvement with high-dose penicillin. Pneumonia caused by S. pneumoniae appeared to be treated safely and effectively with high-dose penicillin based on positive results of the urine antigen test, as penicillin resistance was unlikely to be a problem.

Spectral domain optical coherence tomography of multi-MHz A-scan rates at 1310 nm range and real-time 4D-display up to 41 volumes/second.
Biomed Opt Express
Show Abstract
Hide Abstract
An ultrafast frequency domain optical coherence tomography system was developed at A-scan rates between 2.5 and 10 MHz, a B-scan rate of 4 or 8 kHz, and volume-rates between 12 and 41 volumes/second. In the case of the worst duty ratio of 10%, the averaged A-scan rate was 1 MHz. Two optical demultiplexers at a center wavelength of 1310 nm were used for linear-k spectral dispersion and simultaneous differential signal detection at 320 wavelengths. The depth-range, sensitivity, sensitivity roll-off by 6 dB, and axial resolution were 4 mm, 97 dB, 6 mm, and 23 ?m, respectively. Using FPGAs for FFT and a GPU for volume rendering, a real-time 4D display was demonstrated at a rate up to 41 volumes/second for an image size of 256 (axial) × 128 × 128 (lateral) voxels.

Hospital-acquired pneumonia in Japan may have a better mortality profile than HAP in the United States: a retrospective study.
J. Infect. Chemother.
Show Abstract
Hide Abstract
The characteristics of hospital-acquired pneumonia (HAP) are not well documented. In the present study we investigated the severity and mortality, microbiological profile, and the value of Gram staining in culture-confirmed HAP in a Japanese hospital by retrospective review conducted at a Japanese university hospital. Only culture-confirmed cases with good specimen quality were included in the analysis. The clinical characteristics of HAP, as well as the causative organisms, were investigated. Furthermore, the prognostic ability of existing prediction rules were evaluated for prediction of overall mortality. Forty-two cases were enrolled in this analysis. The majority of patients were admitted to the ICU (61.9 %), and 40.5 % had ventilator-associated pneumonia (VAP). The 30-day mortality was 23.8 %, which is less than that reported in the United States. Factors commonly known to be associated with worse outcome in the USA did not appear to influence the mortality from HAP in Japan. The most frequent causative organisms were methicillin-resistant Staphylococcus aureus (MRSA), followed by Pseudomonas spp. Sensitivity and negative predictive value of Gram staining were 89.4 and 85.7 %, respectively. SMART-COP predicted 30-day mortality with an area under the ROC curve (AUC) >0.7. The characteristics of HAP in Japan differ from HAP reported in the USA. In addition to lower mortality, we found both fewer ICU cases and VAP. Gram staining of good-quality specimens demonstrated promising sensitivity to predict the causative organisms. SMART-COP predicted mortality with appropriate ROC curve (AUC).

Coincidence of HPV11-Positive Urethral Condyloma Acuminatum and HPV-Negative Multiple Bladder Papillomas in a Female.
Case Rep Med
Show Abstract
Hide Abstract
Human papillomaviruses (HPVs) are associated with proliferative lesions in a variety of human epithelial types. A 38-year-old female presented with a diagnosis of urethral condyloma acuminatum. She underwent transurethral resection of the urethral condyloma. At that time, multiple (five) bladder tumors were simultaneously found and also removed by transurethral resection. Four of the bladder tumors were diagnosed as squamous papilloma, and the other was urothelial inverted papilloma. Postoperative course was uneventful. Genomic DNA was extracted from 10??m thick sections of each bladder tumor as well as urethral condyloma. Then, 16 types of HPV DNA sequences were assessed with the PapiPlex method using genomic DNA samples extracted from each bladder tumor as well as urethral condyloma. HPV-11 was detected in DNA extracted from the urethral condyloma, while no HPV DNA sequences were positive in any of the genomic DNA samples extracted from the bladder tumors.

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.
