Diagnostic Performance of an Artificial Intelligence System in Breast Ultrasound.

2021

Objectives We study the performance of an artificial intelligence (AI) program designed to assist radiologists in the diagnosis of breast cancer, relative to measures obtained from conventional readings by radiologists. Methods A total of 10 radiologists read a curated, anonymized group of 299 breast ultrasound images that contained at least one suspicious lesion and for which a final diagnosis was independently determined. Separately, the AI program was initialized by a lead radiologist and the computed results compared against those of the radiologists. Results The AI program's diagnoses of breast lesions had concordance with the 10 radiologists' readings across a number of BI-RADS descri…

Kutane Manifestationen der essentiellen Thrombozyth�mie Erythromelalgie, isch�mische Akrozyanose, Livedo racemosa*

1995

A case report is presented to illustrate the cutaneous manifestations in essential thrombocythaemia. Knowledge of the related skin lesions may lead to earlier detection of this myeloproliferative disorder. Treatment may prevent severe haemorrhagic or thrombotic complications. Erythromelalgia is causally related to thrombocythaemia; prompt relief of painful symptoms after treatment with aspirin is typical.

Role of virtopsy in the post-mortem diagnosis of drowning.

2014

Purpose: Due to admitted limits of autopsy-based studies in the diagnosis of drowning, virtopsy is considered the new imaging horizon in these post-mortem studies. The aim of our study was to evaluate the role of virtopsy performed through computed tomography (CT) in the forensic diagnosis of drowning. Materials and methods: We retrospectively examined the CT data of four cadavers recovered from sea water and suspected to have died by drowning. Each patient underwent a full-body post-mortem CT scan, and then a traditional autopsy. Conclusion: To date, there are no autopsy findings pathognomonic of drowning. This study proves that virtopsy is a useful tool in the diagnosis of drowning in tha…

Precursors of bipolar disorders: A systematic literature review of prospective studies

2015

Objective To evaluate the presence of affective signs and symptoms as precursors of bipolar disorder in prospective studies, including assessment of their prevalence, duration, and predictive value. Data sources We followed PRISMA guidelines to search PubMed, CINAHL, PsycINFO, EMBASE, SCOPUS, and ISI Web of Science databases to May 31, 2013, using the terms bipolar disorder AND (antecedent* OR predict* OR prodrom* OR prospect*) AND (diagnosis OR development). Hand searching of identified reports led to additional relevant references. Study selection We included only English-language articles containing (1) prospective, longitudinal studies with at least 2 structured clinical assessments (in…

Prepare the smoking cessation in severe mental illness: Early diagnosis and prevention opportunities

Dental considerations in patients with respiratory problems.

2011

Many respiratory disorders can compromise routine dental care and require special treatment for the affected patients. Patients often visit the dental clinic with respiratory problems already diagnosed by other specialists. The dental professional therefore must provide correct dental care in the context of such a diagnosis. The present study offers a literature review of those respiratory disorders which can have implications for dental care. Chronic obstructive pulmonary disease (COPD) and asthma require special measures, such as working with the patient in the vertical position, since some of these subjects do not tolerate decubitus. On the other hand, patients with COPD can suffer infec…

The impact of psychopharmacology on contemporary clinical psychiatry.

2014

Clinical psychiatric evaluations of patients have changed dramatically in recent decades. Both initial assessments and follow-up visits have become brief and superficial, focused on searching for categorical diagnostic criteria from checklists, with limited inquiry into patient-reported symptomatic status and tolerability of treatments. The virtually exclusive therapeutic task has become selecting a plausible psychotropic, usually based on expert consensus guidelines. These guidelines and practice patterns rest mainly on published monotherapy trials that may or may not be applicable to particular patients but are having a profound impact, not only on modern psychiatric practice but also on…

Addressing Delicate and Variable Cancer Morphology in Spectral Histopathology Using Canine Visceral Hemangiosarcoma

2021

Spectral histopathology has shown promise for the classification and diagnosis of tumors with defined morphology, but application in tumors with variable or diffuse morphologies is yet to be investigated. To address this gap, we evaluated the application of Fourier transform infrared (FTIR) imaging as an accessory diagnostic tool for canine hemangiosarcoma (HSA), a vascular endothelial cell cancer that is difficult to diagnose. To preserve the delicate vascular tumor tissue structure, and potential classification of single endothelial cells, paraffin removal was not performed, and a partial least square discrimination analysis (PLSDA) and Random Forest (RF) models to classify different tiss…

Hepatocellular carcinoma with macrovascular invasion: multimodality imaging features for the diagnosis

2020

Hepatocellular carcinoma (HCC) is frequently associated with macrovascular invasion of the portal vein or hepatic veins in advanced stages. The accurate diagnosis of macrovascular invasion and the differentiation from bland non-tumoral thrombus has significant clinical and management implications, since it narrows the therapeutic options and it represents a mandatory con-traindication for liver resection or transplantation. The imaging diagnosis remains particularly challenging since the imaging features of HCC with macrovascular invasion may be subtle, espe-cially in lesions showing infiltrative appearance. However, each radiologic imaging modality may provide findings suggesting the prese…

"Pure" large cell neuroendocrine carcinoma of the gallbladder. Report of a case and review of the literature

2016

Primary Neuroendocrine Tumours (NETs) of the gallbladder are rare. Among all NETs of the gallbladder, large cell neuroendocrine carcinoma (LCNEC) is exceedingly rare. In most of the cases LCNECs are combined with other histological components. We reviewed clinical presentation and management of all patients with "pure" LCNEC from published literature since the first case was published in 2000, as well as one patient from our experience. Only 7 cases of "pure" LCNEC has been described in the last 15 years, our case is the eighth. The diagnosis of gallbladder NETs is rarely made preoperatively since the presentation generally consists of non-specific symptoms including upper abdominal pain, d…
