2011 Chinese Optics Letters (COL)  
We investigate the computer-generated hologram with full parallax and which can be reconstructed with white light. The object of the hologram is processed from three-dimensional computer graphics polygon data and has shaded surface for hidden surface removal. The optically reconstructed image from the printed hologram is evaluated.

We reviewed the case of 40 patients with parotid tumor who underwent an operation in the past five years. Results:The patients included 23 (57.5 %) males and 17 (42.5 %) females. The average age was 53.4 years old with a range of 19 to 71 years. Thirty eight (95.0%) had benign tumor, and 2 (5.0%) had malignant tumor. Tc scintigraphy was performed in 37 out of the 40 patients, and 9 patients showed positive results. Six patients had warthin's tumor, and 3 had pleomorphic adenoma. In other words,

None of the cases had permanent facial palsy as a postoperative complication. Transient facial palsy was exhibited by 13 patients (32.5 %), but they all improved 2 weeks to 6 months. In addition, we experienced 1 case of salivary fistula. Discussion:Pleomorphic adenoma was noted in 63.2%, and warthin's tumor in 23.7%. There was no gender difference for pleomorphic adenoma, but 8 out of the 9 patients with warthin's tumor were men. The average age was 47.0 for pleomorphic adenoma and 58.7 for warthin's tumor which was in accordance with conventional reports. The Tc scintigraphy positive rate of warthin's tumor was low, 66.7 %, in comparison with that in conventional reports. In addition, 90% of the tumors that showed positive results in Ga scintigraphy were preoperatively positive tumors, indicating the diagnostic usefulness of this. Transient facial palsy was a complication in 32.5% of the patients, which was similar to the rate in the conventional report. We experienced 1 case salivary fistula, which did not improve with conservative treatment. We opened the wounded area, and drained it by pressing.

Spontaneous Tonsillar Hemorrhage
Spontaneous Tonsillar Hemorrhageの原因

2003 Practica Oto-Rhino-Laryngologica  
Eleven patients diagnosed with spontaneous tonsillar hemorrhage (STH) of noniatrogenic/nontraumatic causes are reported and discussed. Patients ranged from 4 to 63 years old (29.6 on average), consisting of six males and five females. Eight of the eleven STHs were secondary to acute tonsillitis without any hematologic disorders. Two cases of STH were observed in patients with idiopathic thrombocytopenic purpura;one case involved acute tonsillitis. In an elderly female patient, there was diffuse

In ten patients, the bleeding stopped spontaneously;in one patient, oxidized cellulose application by local pressure was used for hemostasis. STH is not a disease, but symptomatic bleeding from the tonsil, mainly associated with acute tonsillitis, and it may be frequently overlooked without recognition of this rare entity.

2021 Open Heart  
There is a high prevalence of left ventricular diastolic dysfunction (LVDD) in systemic sclerosis (SSc) which is associated with high mortality. Thus, early detection of LVDD could be important in management of SSc. We hypothesised that exercise echocardiography in SSc patients with normal resting haemodynamics may expose early phase LVDD, which could affect its prognosis, defined as cardiovascular death and unplanned hospitalisation for heart failure. Between January 2014 and December 2018, we
more » ... prospectively enrolled 140 patients with SSc who underwent 6-minute walk (6MW) stress echocardiographic studies with normal range of estimated mean pulmonary arterial pressure (mPAP) (<25 mm Hg) and mean pulmonary artery wedge pressure (mPAWP) (<15 mm Hg) at rest. We used ΔmPAP/Δcardiac output (CO) to assess pulmonary vascular reserve and ΔmPAWP/ΔCO to assess LV cardiac reserve between resting and post-6MW. During a median period of 3.6 years (IQR 2.0-5.1 years), 25 patients (18%) reached the composite outcome. Both ΔmPAP/ΔCO and ΔmPAWP/ΔCO in patients with events were significantly greater than in those without events (8.9±3.8 mm Hg/L/min vs 3.0±1.7 mm Hg/L/min; p=0.002, and 2.2±0.9 mm Hg/L/min vs 0.9±0.5 mm Hg/L/min; p<0.001, respectively). Patients with both impaired LV cardiac reserve (ΔmPAWP/ΔCO>1.4 mm Hg/L/min) and impaired pulmonary vascular reserve (ΔmPAP/ΔCO>3.0 mm Hg/L/min) had worse outcomes compared with those without these abnormalities (p<0.001). The 6MW stress echocardiography revealed impaired LV cardiac reserve in SSc patients with normal resting haemodynamics. Furthermore, LV cardiac reserve independently associates with clinical worsening in SSc, providing incremental prognostic utility, in addition to pulmonary vascular parameters.

High Resolution Computer-Generated Rainbow Hologram

Takeshi Yamaguchi, Hiroshi Yoshikawa
2018 Applied Sciences  
We have developed an output device for a computer-generated hologram (CGH) named a fringe printer, which can output a 0.35- μ m plane-type hologram. We also proposed several CGH with a fringe printer. A computer-generated rainbow hologram (CGRH), which can reconstruct a full color 3D image, is one of our proposed CGH. The resolution of CGRH becomes huge (over 50 Gpixels) due to improvement of the fringe printer. In the calculation, it is difficult to calculate the whole fringe pattern of CGRH

Furthermore, since the fine pixel pitch provides a wide viewing angle in CGRH, object data, which are used in fringe calculation, should be created from many viewpoints to provide a proper hidden surface removal process. The fringe pattern of CGRH is calculated in each horizontal block. Therefore, the object data from several view points should be organized for efficient computation. This paper describes the calculation algorithm for huge resolution CGRH and its output results.
