Focal nodular hyperplasia-like lesions in patients with cavernous transformation of the portal vein: prevalence, MR findings and natural history.
2011
PURPOSE: To retrospectively investigate the prevalence, MR findings, natural history, and association with other hepatic lesions of focal nodular hyperplasia (FNH)-like lesions in a cohort of consecutive patients with cavernous transformation of the portal vein (CTPV). MATERIALS AND METHODS: This retrospective IRB-approved study comprised 58 patients (32 men, 26 women; average age, 50 years) with CTPV who underwent liver MR imaging between 2000 and 2008. MR images were assessed by two radiologists in consensus for the presence of (a) FNH-like lesions and other liver lesions, and (b) other imaging findings. Patients were assigned to a stable or progressive clinical course based on lesion cha…
Benign paroxysmal positional vertigo following whiplash injury: a myth or a reality?
2011
Abstract Objective The aim of the study was to evaluate the true incidence, diagnosis, and treatment of benign paroxysmal positional vertigo (BPPV) arising after whiplash injury and to distinguish this type of posttraumatic vertigo from other types of dizziness complained after trauma. Methods This was a retrospective study comprising patients referred to our center after whiplash injury. The patients were evaluated with neurotologic examination including bedside and instrumental tests. A Dizziness Handicap Inventory evaluating the symptoms of patients was submitted before and after treatment and was evaluated. The BPPV patients were separately evaluated from those with cervicogenic vertigo…
Are postural restrictions necessary for management of posterior canal benign paroxysmal positional vertigo?
2011
Objectives: An important component of management of benign paroxysmal positional vertigo (BPPV) has been the application of postural restrictions after use of a canalith repositioning maneuver (CRM) to prevent the return of otolithic debris into the posterior semicircular canal (PSC). This study was designed to explore the effectiveness of postural restrictions in patients with BPPV caused by otolithic debris in the PSC. Methods: Seventy-four adult patients with unilateral PSC BPPV were enrolled into this study. All patients were managed with a CRM — Either the modified Epley maneuver or the Semont maneuver. The patients were divided randomly into 2 groups: Group A, with postural restrictio…
Management of benign paroxysmal positional vertigo of lateral semicircular canal by Gufoni's manoeuvre
2009
Abstract Benign paroxysmal positional vertigo (BPPV) of lateral semicircular canal (LSC) is one of the rarer forms of BPPV as compared to posterior semicircular canal BPPV. Various particle repositioning manoeuvres have been described in the literature as a mode of treating this condition. Purpose Evaluation and discussion of the procedure of the Gufoni's manoeuvre and its advantages in the treatment of BPPV of LSC. Material and methods Prospective study of 58 patients affected by LSC BPPV who were office-treated with Gufoni's manoeuvre. Results Seventy-nine percent of the patients so treated had complete resolution of symptoms, and 6.9% did not show any improvement in their symptoms. The r…
Comparison of repositioning maneuvers for benign paroxysmal positional vertigo of posterior semicircular canal: advantages of hybrid maneuver.
2012
Objective: The prevalence of benign paroxysmal positional vertigo (BPPV) is becoming more frequent in elderly population. The presence of comorbid factors has to be considered before assessment as well as before commencing any repositioning treatment. Our aims were evaluation of the maneuvers efficacy and evaluation of the applicability of hybrid maneuver (HM) in patients with physical limitation. Study design and setting: This is a randomized study in 2 tertiary referral centers. Intervention: This is a therapeutic intervention. Patients: All consecutive patients with diagnosis of BPPV of posterior canal matching the inclusion criteria were enrolled. Patients underwent treatment soon after…
Granular cell tumor of the oral cavity; a case series including a case of metachronous occurrence in the tongue and the lung
2014
The granular cell tumor (GCT) is a rare, benign tumor that most commonly occurs in the oral cavity, particularly in the anterior part of the tongue. In this study the experience with 16 patients with a GCT observed in a single Institution will be discussed. Although no radicality has been obtained in most cases, recurrences are rare. In one patient, a recurrence was noted four years after excision of the primary. In the same patient a pulmonary lesion occurred five years after excision of the recurrence in the oral cavity, most likely representing an example of metachronous occurrence and not a distant metastasis. Since recurrences and metachronous lesions are rare, as are distant metastase…
Benign and Atypical Meningioma Metabolic Signatures by High-Resolution Magic-Angle Spinning Molecular Profiling
2008
Meningiomas are neoplasms that arise from the leptomeningeal covering of the brain and spinal cord, accounting for 15%-20% of CNS tumors. The WHO classifies meningiomas into three histological grades: benign, atypical, and anaplasic in accordance with the clinical prognosis. Atypical and anaplasic meningiomas tend to recur. Sometimes, meningiomas with histological diagnosis of benign meningioma show clinical characteristics of atypical meningioma. In this context, high-resolution magic-angle spinning (HR-MAS) spectroscopy of intact tissue from brain tumor biopsies has shown great potential as a support diagnostic tool. In this work, we show differences between benign and atypical meningioma…
Benign paroxysmal positioning vertigo: diagnosis and therapy using video-oculographic control.
2003
In this prospective study, 82 patients (40 males, 42 females, aged between 15 and 80 years) with benign paroxysmal positioning vertigo (BPPV) were treated with different positioning manoeuvres using video-oculographic control. The maximum age for females and males was 31 and 40 years respectively. After an interview about the special history related to vertigo imbalance symptoms and using video-oculographic control, we diagnosed 79 patients with BPPV of the posterior semicircular canal and 3 of the horizontal semicircular canal. The Dix-Hallpike and Cawthorne manoeuvres were used for the diagnosis of BPPV of the posterior semicircular canal and the McClure manoeuvre for the diagnosis of BPP…
CEUS in the differential diagnosis between biliary sludge, benign lesions and malignant lesions
2017
Abstract PURPOSE: Conventional grayscale ultrasound (US) is accurate in the diagnosis of gallbladder disease (GD), but in some cases, it is not decisive. Contrast-enhanced ultrasound (CEUS) improves the diagnostic accuracy of US. The primary objective of this study is to assess the reliability of CEUS in the diagnosis of sludge; the secondary objective is to assess the ability of CEUS to diagnose cancer. METHODS: We retrospectively reviewed the US of 4137 patients positive for GD. In 43/4137 (1.04%), the use of could not discriminate between sludge and neoplasms. Then, we evaluated CEUS in only 39 of these patients, and in 4/43 (9%) cases it was not performable. After CEUS, the absence of e…
