Endometrial response to concurrent treatment with vaginal progesterone and transdermal estradiol.
2012
ABSTRACT Objective To describe the effect of the intermittent administration of vaginal progesterone and a low-dose estradiol patch on endometrial stability, as assessed by the rate of amenorrhea and endometrial stimulation. Methods This was an open study in which 64 moderately symptomatic, postmenopausal women were treated in the outpatient clinic of our University Hospital for different intervals up to 1 year. The treatment consisted of a combination of patches delivering 25 µg/day estradiol and intravaginal pills containing 100 mg of micronized progesterone. Patches and pills were administered concomitantly in a twice-a-week protocol. The endometrial response was assessed by endovaginal …
EFSUMB Guidelines 2011: Comment on Emergent Indications and Visions
2012
The focus of this article is the emergent and potential indications of contrast-enhanced ultrasound (CEUS). Emergent applications of CEUS techniques include extravascular and intracavitary contrast-enhanced ultrasound, quantitative assessment of microvascular circulation for tumor response assessment, and tumor characterization using dynamic contrast-enhanced ultrasound (DCE-US). Potential indications for microbubble agents include novel molecular imaging and drug and gene delivery techniques, which have been successfully tested in animal models.

Association between low-frequency ultrasound and hip fractures - comparison with DXA-based BMD
2013
Background New methods for diagnosing osteoporosis and evaluating fracture risk are being developed. We aim to study the association between low-frequency (LF) axial transmission ultrasound and hip fracture risk in a population-based sample of older women. Methods The study population consisted of 490 community-dwelling women (78–82 years). Ultrasound velocity (VLF) at mid-tibia was measured in 2006 using a low-frequency scanning axial transmission device. Bone mineral density (BMD) at proximal femur measured using dual-energy x-ray absorptiometry (DXA) was used as the reference method. The fracture history of the participants was collected from December 1997 until the end of 2010. Lifestyl…
Fisurectomy and anoplasty with botulinum toxin injection in patients with chronic anal posterior fissure with hypertonia: a long-term evaluation.
2020
AbstractChronic anal fissure’s (CAF) etiopathogenesis remain unclear. CAF of the posterior commissure (CAPF) are often characterized by internal anal sphincter (IAS) hypertonia. The treatment of this disease aimed to reduce IAS hypertonia. Due to the high rate of anal incontinence after LIS, the employment of sphincter preserving surgical techniques associated to pharmacological sphincterotomy appears more sensible. The aim of our study is to evaluate the long-term results of fissurectomy and anoplasty with V–Y cutaneous flap advancement associated to 30 UI of botulinum toxin injection for CAPF with IAS hypertonia. We enrolled 45 patients undergone to fissurectomy and anoplasty with V–Y cut…
New Hope in Brain Glioma Surgery: The Role of Intraoperative Ultrasound. A Review
2018
Maximal safe resection represents the gold standard for surgery of malignant brain tumors. As regards gross-total resection, accurate localization and precise delineation of the tumor margins are required. Intraoperative diagnostic imaging (Intra-Operative Magnetic Resonance-IOMR, Intra-Operative Computed Tomography-IOCT, Intra-Operative Ultrasound-IOUS) and dyes (fluorescence) have become relevant in brain tumor surgery, allowing for a more radical and safer tumor resection. IOUS guidance for brain tumor surgery is accurate in distinguishing tumor from normal parenchyma, and it allows a real-time intraoperative visualization. We aim to evaluate the role of IOUS in gliomas surgery and to ou…
Aszites und vermeintliches akutes Abdomen bei hereditärem Angioödem durch C1-Inhibitor-Mangel
2008
HISTORY AND CLINICAL FINDINGS A 35-year-old man, for 8 years known to have hereditary angio-oedema with recurrent cutaneous swellings and occasional attacks of gastrointestinal pain, developed very painful, colic-like upper abdominal symptoms and frequent vomiting. INVESTIGATIONS Routine laboratory tests were normal, except for leucocytosis of 18,200 WBC/microliter. The plasma concentrations of C1-esterase inhibitor (5.6 mg/dl) and of complement factor C4 (10.0 mg/dl) were reduced. Computed tomography revealed about 500 ml free fluid, a perihepatic effusion and definite oedematous thickening of the ileal wall. TREATMENT AND COURSE During conservative treatment with infusions and no food by …
Hardwiring the Brain: Endocannabinoids Shape Neuronal Connectivity
2007
The roles of endocannabinoid signaling during central nervous system development are unknown. We report that CB 1 cannabinoid receptors (CB 1 Rs) are enriched in the axonal growth cones of γ-aminobutyric acid–containing (GABAergic) interneurons in the rodent cortex during late gestation. Endocannabinoids trigger CB 1 R internalization and elimination from filopodia and induce chemorepulsion and collapse of axonal growth cones of these GABAergic interneurons by activating RhoA. Similarly, endocannabinoids diminish the galvanotropism of Xenopus laevis spinal neurons. These findings, together with the impaired target selection of cortical GABAergic interneurons lacking CB 1 Rs, identify endoc…
Noninvasive diagnostic techniques of port wine stain.
2021
Port-wine stain (PWS) is a benign capillary malformation that most commonly occurs in the head and neck. It is present at birth and progresses over time. It is formed by progressive dilatation of post-capillary venules and is associated with hypertrophy and nodularity with increasing age, leading to cosmetic disfigurement and psychological aggravation. It is caused by genetic mosaicism in GNAQ and GNA11 genes. Histopathology is the gold standard for assessment of PWS but it is invasive and may cause scarring. Inadequate characterization of the lesions may predispose to inadequate treatment protocols as well as higher treatment dosages. Clinical evaluation of treatment efficacy is subjective…
Computerized analysis of normal fetal heart rate pattern throughout gestation.
2009
Objective To analyze the evolution of computerized cardiotocography (cCTG) parameters throughout gestation in a large archive of traces from healthy fetuses. Methods This was a cross-sectional study of the first cCTG record from 4412 singleton fetuses with good pregnancy outcome. Normal ranges of cCTG parameters for 25 to 42 weeks were derived from analysis of only one cCTG record per fetus, and the relationship between the parameters and gestational age was investigated. Results Fetal heart rate (FHR) accelerations, short- and long-term variation overall, duration of episodes of high and low variation and variation in high episodes increased with advancing gestation. In contrast, maternal …
Sonographic examination of epiaortic vessels in patients with peripheral vertigo
2010
To evaluate the utility of echo-color-Doppler ultrasonography (CDU) of extracranial brain-supplying vessels in patients with peripheral vertigo of unknown origin.One-hundred-fifty-six patients (study group; 42 male and 114 female; mean age 61.86 ± 14.14) and 161 patients (control group; 80 male and 81 female; mean age 62.31 ± 13.69) were prospectively evaluated with CDU of extracranial brain-supplying vessels. Plaques in common and/or internal carotid artery (CA), arterial wall intima-media thickness (IMT) of common CA and peak systolic velocity (PSV) and resistive index (RI) of vertebral arteries (VA) were evaluated. Parametric (t-test) and non-parametric (Mann-Whitney U-test and Kolmogoro…
