Clinical Features and Natural History of AMD on OCT
2009
Despite recent progress, age-related macular degeneration (AMD) remains the leading cause of vision loss in high-income countries, and its incidence appears to be increasing, probably due to longer life span and improved methods of detection.
Classic Choroidal Neovascularization
2009
Since Donald Gass’s pioneering work in 1967, which demonstrated the role of choroidal neovascularization (CNV) in wet (exudative) AMD, visible (classic) CNV, well demarcated and well-defined on fluorescein angiography, has become the most characteristic form of AMD.
Abduction saccades in unilateral internuclear ophthalmoplegia
1990
Horizontal eye movements were investigated in 60 consecutive patients with unilateral internuclear ophthalmoplegia utilizing direct current electrooculography. In nine patients additional conjugated slowing of ipsiversive saccades indicated the diagnosis of a one-and-a-half syndrome. Slowing of abduction saccades was bilateral in two patients and unilateral in 20 (ipsilateral to the MLF lesion in 17 patients and contralateral in three). Slowing of abduction saccades was attributed to impaired inhibition of the tonic resting activity of the antagonistic medial rectus muscle. On the eye contralateral to the lesion 70% of the patients had abduction nystagmus and 66.7% hy permetric abduction sa…
Zum Einsatz des Ultraschalls in der Diagnostik von Nase und Nasennebenhöhlen
2005
Ultrasound is commonly performed to diagnose pathological processes of the neck and the salivary glands. In contrast, pathological changes of the sinuses and the bony structures of the face are only rarely examined sonographically. This paper deals with the diagnostic scope of ultrasound in the case of orbital and nasal fractures as well as for cases of sinus pathology excluding acute sinusitis. 51 patients with different diseases of this area were examined using US and X-ray or CT scan. Fractures of the nose could all be diagnosed correctly by ultrasound, which is of clinical importance if children or pregnant patients are examined. Blow-out fractures of the orbit were not detected. In con…
Clinical Features and Natural History of AMD
2009
Over recent years, OCT has become an essential part of the examination in routine follow up for AMD to guide clinical practice and analyze the response to treatment. OCT examinations can clearly demonstrate the efficacy of treatment by showing regression or persistence of leakage. Moreover, alterations of the outer retinal layers can also be analyzed.
Laparoendoscopic single-site surgery for the treatment of benign adnexal disease: a prospective trial.
2010
Background. To validate feasibility, efficacy, and safeness of laparoscopic treatment of benign adnexal diseases through a single transumbilical access (LESS) in a prospective series of patients. Methods. A prospective clinical trial including 30 women has been conducted at the Division of Gynecology of Catholic University of Sacred Hearth of Rome. Patients underwent different laparoscopic procedures by LESS utilizing a multiport trocar and conventional straight laparoscopic instrumentation. Intra and perioperative outcome has been reported. Results. Ten mono/bilateral adnexectomies and 20 cystectomies have been performed by LESS approach. Laparoscopic procedures were completed through a si…
Intradiverticular Ampulla of Vater: Personal Experience at ERCP
2013
Introduction. Conflicting results have been reported about the true impact of intradiverticula ampulla (IA) on the technical success and complication rate of endoscopic retrograde cholangiopancreatography (ERCP). Patients. A total of 500 patients who underwent ERCP were divided into two groups according to the presence (group A, 81 patients) or absence (group B, 419 patients) of IA. Success rate, difficulty at cannulation, findings at ERCP, and procedure-related complications were retrospectively reviewed. Results. Successful cannulation was achieved in 100% of group A patients compared to 98% of group B patients (P = ns). There was a significant difference in the type of cannulation that w…
Detection of liver metastases in cancer patients with geographic fatty infiltration of the liver: the added value of contrast-enhanced sonography
2017
Purpose The aim of this study is to assess the role of contrast-enhanced ultrasonography (CEUS) in the detection of liver metastases in cancer patients with geographic liver fatty deposition on greyscale ultrasonography (US). Methods Thirty-seven consecutive cancer patients (24 women and 13 men; age, 33 to 80 years; mean, 58.1 years) with geographic liver fatty deposition, but without any detectable focal liver lesion on greyscale US, underwent sulphur hexafluoride-enhanced US. Two readers reported by consensus the presence, size, and location of any detected lesion. All patients underwent magnetic resonance imaging (MRI) as a confirmatory study. Sensitivity, specificity, positive and negat…
Oropharyngeal Hairy Polyp: A Case of Respiratory Failure in a Newborn
2020
Hairy polyps, also known as dermoid polyps (DPs), are rare benign cystic lesions of bigerminal origin that may occur in several head and neck regions, including the oropharynx. Despite their benign histopathological nature, DPs may be life threatening, due to their upper airway location, and DPs represent one of the most unusual causes of respiratory distress during the neonatal period. In this paper, we describe a case of respiratory failure in a newborn with an oropharyngeal mass that was accidentally found during difficult intubation. Magnetic resonance imaging (MRI) detected a well-defined soft tissue pedunculated mass, arising from the left oropharynx wall, consistent with an oropharyn…
Advances in detection and characterization of atherosclerosis using contrast agents targeting the macrophage
2006
With advances in imaging technology and our understanding of the role of inflammation in atherosclerosis, the macrophage appears to be an excellent target for imaging the progression of disease. In addition to imaging the macrophage with only 1 modality, contrast agents can be created that can be imaged with multiple modalities. This seems extremely attractive, as lesion morphology and characteristics can be determined with modalities that provide high picture resolution, such as CT or MRI, whereas macrophage quantity can be accurately determined through the creation of a radiolabeled contrast agent such as FDG via PET. Although this combination of imaging technologies may yield clinically …
