OBJECT: Primary steps in the cavernous angiomas (CAs) surgery are a precise lesion identification and an optimal trajectory definition. Doing so, navigation techniques allow better results compared to microsurgery alone. In this paper we define the benefits of Intra-Operative Ultra-Sound (IOUS) use in addition to standard localization systems. METHODS: We retrospectively analyzed 59 CAs comparing two groups: 34 cases of frame-based and frameless navigation-assisted microsurgery (no-IOUS group) versus 25 cases of IOUS-guided microsurgery associated with these techniques (IOUS group)...

Pregnancy-associated uterine artery pseudoaneurysm (UAP) usually requires transarterial embolization (TAE) irrespective of the presence/absence of current bleeding. Some UAP cases spontaneously resolve without TAE; however, such UAP is not well characterized. Here, we suggest that Pulse Wave Doppler may become an addition to predict its spontaneous resolution. A woman underwent 1st-trimester vaginal termination. Vaginal bleeding repeated and, 36 days later, an intrauterine low-echoic mass (24 mm) with swirling blood flow and arterial waveforms (Pulse Wave Doppler) and an enhanced intrauterine sac-like structure without current extravasation were observed, leading to the diagnosis of UAP...

The reported frequency of malignant diseases in unilocular cysts varies in different studies, giving conflicting results. To quantify the risk of malignancies among echoic and anechoic unilocular adnexal cysts, in premenopausal and postmenopausal women, we performed a PubMed/MEDLINE search of papers published in English evaluating the histopathological diagnoses of removed ovarian cysts diagnosed as simple unilocular cysts at pre-operative ultrasound examination. From 34 selected publications, we extracted data on ovarian malignancy in the total series, and separately for premenopausal and postmenopausal women, and women with cysts < 5 cm and  ≥5 cm in diameter...

Onco-testicular sperm extraction is used to preserve fertility in patients with bilateral testicular tumors and azoospermia. We report the case of a testicular tumor in the solitary testis of a patient who had previously undergone successful contralateral orchiectomy and whose sperm was preserved by onco-testicular sperm extraction. A 35-year-old patient presented with swelling of his right scrotum that had lasted for 1 month. His medical history included a contralateral orchiectomy during childhood. Ultrasonography revealed a mosaic echoic area in his scrotum, suggesting a testicular tumor...

In the present study, we examined whether rosmarinic acid (RA) reverses amyloid β (Aβ) induced reductions in antioxidant defense, lipid peroxidation, cholinergic damage as well as the central auditory deficits. For this purpose, Wistar rats were randomly divided into four groups; Sham(S), Sham + RA (SR), Aβ42 peptide (Aβ) and Aβ42 peptide + RA (AβR) groups. Rat model of Alzheimer was established by bilateral injection of Aβ42 peptide (2,2 nmol/10 μl) into the lateral ventricles. RA (50 mg/kg, daily) was administered orally by gavage for 14 days after intracerebroventricular injection...

Speech perception behavioral research suggests that rates of sensory memory decay are dependent on stimulus properties at more than one level (e.g., acoustic level, phonemic level). The neurophysiology of sensory memory decay rate has rarely been examined in the context of speech processing. In a lexical tone study, we showed that long-term memory representation of lexical tone slows the decay rate of sensory memory for these tones. Here, we tested the hypothesis that long-term memory representation of vowels slows the rate of auditory sensory memory decay in a similar way to that of lexical tone...

As ultrasound is commonly used these days, more and more lesions are found incidentally, including simple cysts, isoechoic nodules, and hypoechoic nodules, such as ectopic thymus. We here report the prevalence of ectopic thymus and its natural course.We retrospectively reviewed the charts of 690 subjects (342 males, 348 females) who were under 18 years old and had undergone neck or thyroid ultrasound at Hallym University Sacred Heart Hospital from January 2014 to June 2017. Ectopic thymus was defined when the incidental lesion was hypo- to iso-echoic compared to adjacent muscles with vascularity and did not have a connection to the thymus in the mediastinum...

Background: There is relatively little literature on elbow disease in the horse. The only published reports on soft tissue conditions describe collateral ligament and biceps brachii injuries. Case presentation: A three-year old Thoroughbred gelding presented with a history of acute onset right forelimb lameness of less than one week duration, one month after commencing training in a National Hunt racing yard. Physical examination and peri-neural anaesthesia failed to localise the lesion...

PURPOSE: To assess the prevalence of ectopic thyroidal thymus tissue detected by sonography (US) in children and to analyze the US features. METHODS: We retrospectively reviewed images of 216 children who had undergone a thyroid or neck US examination from February 2015 to June 2015. Lesions within or adjacent to the thyroid gland that showed echopatterns consistent with thymic tissue were diagnosed as ectopic thyroidal thymus tissue. Lesions were reviewed according to their side, location, level, size, shape, echo pattern, internal content, and vascularization...

Humans remember the past and use that information to plan future actions. Lab experiments that test memory for the location of food show that animals have a similar capability to act in anticipation of future needs, but less work has been done on animals foraging in the wild. We hypothesized that planning abilities are critical and common in breath-hold divers who adjust each dive to forage on prey varying in quality, location and predictability within constraints of limited oxygen availability. We equipped Risso's dolphins with sound-and-motion recording tags to reveal where they focus their attention through their externally observable echolocation and how they fine tune search strategies in response to expected and observed prey distribution...

The use of ultrasound in differentiation of benign and malignant solid hypo-echoic thyroid nodules is a dilemma in clinical practice. The aim of this study was to investigate the revised value of contrast-enhanced ultrasound (CEUS) for differentiating solid hypo-echoic thyroid nodules using the Thyroid Imaging Reporting and Data System (TI-RADS).The study included 135 patients with 135 nodules confirmed by fine-needle aspiration and/or surgery. Every nodule underwent both conventional US and CEUS. Binary logistic regression analysis for conventional US features revealed that irregular shape, microcalcification and height greater than width were significant malignant predictive features...

Acute funisitis is characterized by the infiltration of fetal neutrophils from the umbilical vessels into Wharton's jelly and presents as fetal inflammation. However, no reports about its prenatal diagnosis using ultrasonography have been published. We encountered one case of oligohydramnios at 26 weeks and another case of threatened premature delivery at 27 weeks of gestation with ultrasonographic findings of non-uniform thickening of Wharton's jelly, a heterogeneous internal echo, and a high echoic line of the umbilical vessel wall...

Tumor cell displacement is occasionally observed in surgical specimens after core needle biopsy. We report a case involving a 58-year-old woman in whom a microlobulated mass was detected on mammography, after which she underwent an ultrasonography- guided core needle biopsy. Thirty-six days later, a new low-echoic lesion was detected on ultrasonography, located from the original mass to the subcutaneous insertion site of the needle biopsy. Fifty days after the biopsy, breast-conserving surgery was performed...
