Objective: We wanted to assess the usefulness of four-dimensional (4D) ultrasonography (US), i.e., real-time three-dimensional US, as an adjunct for performing various US-guided interventional procedures in superficial lesions. Materials and Methods: Thirty-three patients were referred for US-guided interventional procedures for superficial lesions, including core biopsy in 19, fineneedle aspiration in eight, therapeutic drug injection in four and needle puncture in two. The procedures were performed under 4D US guidance. We reviewed the pathologic/cytologic results of the core biopsies or needle aspirations, and also the outcomes of drug injection or needle puncture. Results: For all the patients who underwent 4D US-guided core biopsy, the specimens were adequate for making the pathological diagnosis, and specimens were successfully obtained for those patients who underwent 4D US-guided aspiration. The patients treated with 4D US-guided therapeutic drug injection or needle puncture had a good response. No major procedure-related complications occurred. The procedural times were similar to those procedural times with using two-dimensional US. Conclusion: Combining the two dimensional and 4D US techniques aids the physician when performing US-guided interventional procedures for the superficial lesions.

Lai, Chi-Chun,Wang, Nan-Kai,Wu, Wei-Chi,Yeung, Ling,Hwang, Yih-Shiou,Chen, Kuan-Jen,Chen, Tun-Lu,Chuang, Lan-Hsin Informa Healthcare 2011 Cutaneous and ocular toxicology Vol.30 No.4
<P><I>Purpose</I>: To compare the long-term anatomical and visual outcomes of patients with idiopathic epiretinal membrane (ERM) removed by vitrectomy and membrane peeling with or without the use of intravitreal injection of triamcinolone acetonide (IVTA).</P><P><I>Methods</I>: A retrospective chart review was performed. Subjects who underwent vitrectomy and who were followed over 12 months were included. The study included two groups of patients. In group 1 (71 eyes), the patients underwent vitrectomy and membrane peeling without the use of IVTA. In group 2 (27 eyes), 2 mg of IVTA was given at the end of the surgery. The main outcome measures were best-corrected visual acuity (BCVA), central foveal thickness (CFT) determined by optical coherence tomography (OCT), the number of cataract surgeries, and the use of anti-glaucomatous drugs during the follow-up period.</P><P><I>Results</I>: This study included 98 eyes with ERM from 98 patients. There was no significant difference between the two groups with respect to age, gender, pre- and postoperative lens status, BCVA, CFT, or length of the follow-up period. The mean age for all of the patients was 62.45 ± 10.01 (mean ± SD) years, and the mean follow-up length was 20.58 ± 9.64 (mean ± SD) months. In all cases, the mean best-corrected logarithm of minimum angle of resolution (logMAR) acuity improved from a preoperative value of 0.91 ± 0.32 [Snellen equivalent (SE), 0.16 ± 0.14] to a postoperative value of 0.46 ± 0.36 (SE, 0.46 ± 0.29) (<I>P</I> < 0.0001). The CFT was reduced from a preoperative value of 473.46 ± 96.91 μm to a postoperative value of 302.44 ± 69.80 μm (<I>P</I> < 0.0001). Six patients (22.2%) in group 2 required anti-glaucomatous drugs to control intraocular pressure (IOP) during the follow-up period, and three patients (4.2%) in group 1 required drugs to control IOP (<I>P</I> == 0.012).</P><P><I>Conclusions</I>: The postoperative visual outcomes for patients with idiopathic ERM were favorable, but CFT did not return to a normal level, even in eyes in which 2 mg IVTA was used. The IVTA use after ERM removal produced no significant benefits during long-term follow-up, but IVTA did increase the risk of increased IOP.</P>

Objective: The purpose of this retrospective study was to investigate the relationship between temperature-humidity index (THI), season, and conception rate (CR) of Holstein cows in central Taiwan. Methods: The mean performance and number of observations were statistically evaluated for various parameters, including age at first service, number of days open, gestation length, CR, and calving interval for different parities. Results: The results indicate that the mean age at first service was 493.2 days; the gestation length was similar across all cows of different parities, ranging from 275.1 to 280.7 days. The overall CR of all inseminations was significantly lower in multiparous cows ($47.26%{\pm}0.22%$) than in heifers ($57.14%{\pm}0.11%$) (p<0.05). At THI>72 and during the hot season (from June to November), CRs for multiparous cows were significantly reduced compared to that for heifers, while the ratio remained unchanged among heifers for all seasons. Conclusion: To achieve a high CR, lactating cows should be bred in winter and spring (from December to May) from the start of the seasonal breeding program, whereas the heifer should be allowed to breed in summer and fall under the subtropical climate in Taiwan.

Imaging Spectrum after Pancreas Transplantation with Enteric Drainage
Jian-Ling Chen,Rheun-Chuan Lee,Yi-Ming Shyr,Sing-E Wang,Hsiuo-Shan Tseng,Hsin-Kai Wang,Shan-Su Huang,Cheng-Yen Chang 대한영상의학회 2014 Korean Journal of Radiology Vol.15 No.1
Since the introduction of pancreas transplantation more than 40 years ago, surgical techniques and immunosuppressive regiments have improved and both have contributed to increase the number and success rate of this procedure. However, graft survival corresponds to early diagnosis of organ-related complications. Thus, knowledge of the transplantation procedure and postoperative image anatomy are basic requirements for radiologists. In this article, we demonstrate the imaging spectrum of pancreas transplantation with enteric exocrine drainage.
