L Li, M Wu
Evaluation of the vaginal bleeding of postmenopausal women is crucial to diagnose endometrial lesions. Endometrial thickness measured by transvaginal ultrasonography provides an important reference for diagnosis. Currently, no specific cut-off value of endometrial thickness has been identified to predict the malignant risk for endometrial thickening and postmenopausal women without any symptoms. Most of resected endometrial specimens from postmenopausal women without any symptoms are diagnosed as benign or normal tissues...

Autoamputation of the appendix has previously been reported in the literature, but it is likely an unusual event. We report a 2-year-old male child who had previously undergone laparotomy and bowel resection for necrotizing enterocolitis. Two years later a calcified intra-abdominal mass was identified on abdominal radiography and ultrasonography. Eventual laparotomy revealed a densely calcified mass within the transverse mesocolon. The mass was uneventfully resected. Pathologic evaluation showed appendiceal tissue, consistent with prior autoamputation of the vermiform appendix...

Microsurgical subinguinal varicocelectomy (MSV) is generally considered the gold standard nowadays in view of the lower risk of complications and recurrence. To achieve complete ligation of veins while preserving testicular artery (TA) during the procedure remains challenging despite the application of high power optical magnification and micro-Doppler ultrasonography. The use of intraoperative indocyanine green angiography (ICGA) with infrared fluorescence operative micro-scope in MSV potentially lowers the incidence of TA injury and shortens the learning curve of nov-ice surgeons...

Urethral stones can become impacted in the posterior urethra, typically presenting with varying degrees of acute urinary retention and lower urinary tract symptoms. These are traditionally treated in the inpatient setting, with external urethrotomy or endoscopic push-back of the calculus into the urinary bladder followed by cystolitholapaxy or cystolithotripsy. However, these methods are invasive, involve general anesthesia, and require radiation. In this report, we describe a simple, minimally invasive, and safe alternative technique to visualize and remove impacted prostatic urethral stones under the real-time guidance of transrectal ultrasonography (TRUS)...

Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...

Muscle fascicles lengthen in response to chronic passive stretch through in-series sarcomere addition in order to maintain an optimum sarcomere length. In turn, the muscles' force generating capacity, maximum excursion, and contraction velocity is enhanced. Thus, longer fascicles suggest a greater capacity to develop joint power and work. However, static fascicle length measurements may not be taking sarcomere length differences into account. Thus, we considered relative fascicle excursions through passive ankle dorsiflexion may better correlate with the capacity to generate joint power and work than fascicle length...

Previous studies have supported the theory that there is a positive association between ferritin and carotid atherosclerosis in Western people. Diet plays an important role in determining serum ferritin concentration. Asian dietary patterns are different from Western dietary patterns, implying that there may be a difference in the association of ferritin with carotid atherosclerosis between Asian and Western people. However, few studies focus on the association between ferritin and carotid atherosclerosis among Asians...

The objective of this study was to evaluate the changes in uterine blood flow (UBF) based on the resistance index (RI) and the pulsatility index (PI) by Doppler ultrasonography throughout the estrous cycle in lactating Sahiwal cows (n=9). Cows were randomly selected during their spontaneous estrus. UBF was examined on alternate days in all cows during the estrous cycle. The results revealed that the mean RI values were higher (P<0.05) on day -1 (estrus) than on day 0 (ovulation). The mean RI values followed a consistent pattern on days 2, 4, 6, and 8 (metestrus to early diestrus) and were lower (P<0...
