The role of US examination in the management of acute abdomen.

2013

Acute abdomen is a medical emergency, in which there is sudden and severe pain in abdomen of recent onset with accompanying signs and symptoms that focus on an abdominal involvement. It can represent a wide spectrum of conditions, ranging from a benign and self-limiting disease to a surgical emergency. Nevertheless, only one quarter of patients who have previously been classified with an acute abdomen actually receive surgical treatment, so the clinical dilemma is if the patients need surgical treatment or not and, furthermore, in which cases the surgical option needs to be urgently adopted. Due to this reason a thorough and logical approach to the diagnosis of abdominal pain is necessary. …

Lymphatic Mesenteric Cyst, a Rare Cause of Surgical Abdominal Pain: Case Report and Review of the Literature

2020

A lymphatic mesenteric cyst (LMC) is a rare clinical entity, of unclear etiopathogenesis, which can arise in the abdominal cavity or retroperitoneum without a clear origin. We describe a case of a 74-year-old male presenting with abdominal pain that was non-specific and non-responsive to medical therapy. Laboratory tests clinical examination were inconclusive while the abdominal computed tomography (CT) scan showed a cystic lesion of the ileal mesentery. We performed an open surgical excision of the lesion with the resolution of clinical symptoms. The lesion resulted to be an LMC at the histological examination. At the five-year CT scan follow-up, we did not record any recurrences. LMCs pre…

Current advances and novel research on minimal invasive techniques for musculoskeletal disorders.

2021

Abstract The present review summarized the current advances and novel research on minimal invasive techniques for musculoskeletal disorders. Different invasive approaches were proposed in the physical therapy field for the management of musculoskeletal disorders, such as ultrasound-guided percutaneous needle electrolysis, dry needling, acupuncture and other invasive therapy techniques, discussing about their worldwide status, safety and interventional ultrasound imaging. Indeed, dry needling may be one of the most useful and studies invasive physical therapy applications in musculoskeletal disorders of different body regions, such as back, upper limb, shoulder, arm, hand, pelvis, lower limb…

“Ultra-sensitive” cardiac troponins: Requirements for effective implementation in clinical practice

2018

The measurement of cardiac troponins, either cardiac troponin I or T, has become the culprit of clinical decision making in patients with suspected acute coronary syndrome (ACS), especially in those with non-ST elevation myocardial infarction (NSTEMI). The leading analytical mainstays of cardiac troponin immunoassays include the limit of blank (LoB), limit of detection (LoD), functional sensitivity, the 99th percentile of a healthy reference population, along with the percentage of “ostensibly healthy” subjects displaying measurable values 50% in the general healthy population. The very recent commercialization of methods with further improved analytical sensitivity (i.e., “ultra-sensitive”…

The Association Between Quantitative Flow Ratio and Intravascular Imaging-defined Vulnerable Plaque Characteristics in Patients With Stable Angina an…

2021

Background: This study aimed to examine whether quantitative flow ratio (QFR), an angiography-based computation of fractional flow reserve, was associated with intravascular imaging-defined vulnerable plaque features, such as thin cap fibroatheroma (TCFA) in patients with stable angina, and non-ST-segment elevation acute coronary syndrome.Methods: Patients undergoing optical coherence tomography (OCT) or intravascular ultrasound (IVUS) examinations were identified from two prospective studies and their interrogated vessels were assessed with QFR. Lesions in the OCT cohort were classified into tertiles: QFR-T1 (QFR ≤ 0.85), QFR-T2 (0.85 < QFR ≤ 0.93), and QFR-T3 (QFR > 0.93). L…

Speckle tracking analysis in intensive care unit: A toy or a tool?

2018

The use of conventional echocardiography in the intensive care unit (ICU) is today established to assess left and right ventricular systolic function, for preload determination and procedural guidance. Next step in ICU echocardiography could be the use of novel ultrasound techniques such as strain echocardiography to assist in the management of patients with acute coronary syndrome, heart failure, or pulmonary embolism. This review has gathered the available evidence supporting the incremental value of strain in the diagnostic workup of cardiac diseases treated in ICU.

Parameters for coronary plaque vulnerability assessed with multidetector computed tomography and intracoronary ultrasound correlation

2009

In the absence of a fixed relationship between plaque vulnerability and flow-limiting stenosis, alternative morphological expressions exist that could predict the liability of coronary lesions to rapidly progress or rupture, causing acute coronary syndromes. Modern multidetector computed tomography technology is capable of noninvasively detecting lesion location, attenuation, remodeling and calcification pattern, which may be considered as surrogate morphological markers of vulnerability and could contribute to increase the prognostic value of individual coronary plaque burden.

Endoluminal ultrasonic examination of sessile polyps and early carcinomas of the rectum

1989

The results of conventional endosonographic techniques in the assessment of early carcinomas and sessile polyps of the rectum have been unsatisfactory. We therefore developed a new technique in which the rectal cavity is filled directly with water. Using this technique, the anatomy of small rectal tumors is preserved and the layers of the rectal wall are easier to differentiate, especially with a 10-MHz scanner. The clinical results in 66 patients demonstrate that this new technique is very accurate in the preoperative staging of adenomas and T1-carcinomas of the rectum.

Endoscopic management of a case of 'complete septate uterus with unilateral haematometra'

1995

Endoscopy and ultrasound was used to diagnose a 13 year old virgin girl who presented with dysmenorrhoea and suspected right side adnexal tumescence. The girl was found to have a complete septate uterus with non-communicating right hemicavity and haematometra, an exceptional type of Mullerian anomaly. After pretreatment with buserelin, hysteroscopic metroplasty was successfully performed.
