Introduction Breast Adenomyoepithelioma is a benign neoplasm, resembling adenomyoepithelioma of salivary glands. Uncommon, mean age 60 years. Considered a variant of intraductal papilloma. It usually presents as a palpable mass. Treatment Complete local excision. The average age for developing an adenomyoepithelioma of the breast is about 60 years. Some physicians consider a breast adenomyoepithelioma to be a variant of an intraductal papilloma. It also seems to be closely related to a clear cell hidradenoma of the breast. Most breast cancers arise in the breast ducts, which are primarily made of epithelial cells. Epithelial cells are normally associated with tissues such as skin and membranes, while myoepithelial cells tend to be associated with muscle tissue. One would have to say that for an adenomyoepithelioma of the breast, there is a spectrum of possibly disease behaviours.
Discussion: Adenomyoepithelioma was first reported by Hamperl in 1970 as an uncommon biphasic tumor composed of epithelial and myoepithelial cells (3). Adenomyoepitheliomas usually present as a single circumscribed mammary nodule. The fine needle aspiration findings in adenomyoepitheliomas have been described in only a few reports (1, 2, 4-11). It is important to recognize this entity as the radiologic and cytologic features can mimic malignancy. On cytology single enlarged atypical epithelial cells, presumed to be of myoepithelial origin due to staining with S-100 protein have been noted and led to the erroneous diagnosis of carcinoma (6). Only rarely can this diagnosis be made definitively on fine-needle aspiration biopsy (7). Histologic patterns include the tubular, lobulated and spindle cell variants (12). Biphasic pattern consists of tubules lined by cuboidal or columnar shaped epithelial cells surrounded by myoepithelial cell layer, Malignant adenomyoepitheliomas are usually characterized ...

Results The mean age was 51.1±11 years, median disease duration of 6.1 years, 92.8% were females and 92.8% had oral symptoms. The global B-mode score was 22.2 points (13-44) and the RTS global score 2.5 (1.64-3.28) m/seg. We found a correlation between the RTS global score and the global B-mode score (t=0.53, p=0.001), the RTS global score between both parotids (t=0.58, p=0.0001) and both submandibulars (t=0.50, p=0.0001); but not between parotids and submandibular glands. The RTS global score correlated with the NSWSF (t=-0.53, p=0.001), ESSDAI (t=0.31, p=0.03), glandular ESDDAI domain (t=0.36, p=0.02), C4 levels (t=-0.32, p=0.04), but not with the rest of serological variables, chemokines and cytokines levels.. We found fibrosis in 7 patients (26.9%), and these patients were not different when compared to the group without it, regarding the RTS global score, B-mode global score, age and chemokine and cytokines levels, but tended to have a longer disease duration. At the linear regression ...

Acta méd. peruana [online]. 2012, vol.29, n.2, pp.79-84. ISSN 1728-5917.. Objective: The main purpose of this study was to measure the thickness of the flexor tendons using ultrasonography of the hands in type 2 diabetic patients with limited joint mobility in Almanzor Aguinaga- Asenjo Hospital, and to compare these measurements with those recorded in type 2 diabetic patients with no limited joint mobility. Material y Method: Forty-four volunteer patients were recruited in our hospital between December 2009 and March 2010, and they were divided in two groups: those with limited joint mobility and those without this feature. The praying hand maneuver was performed in every patient, afterwards, the painted hand test was performed, in order to assess the degree of functional limitation, and then the ...
Neovascularization contributes to the development of sustained synovial inflammation in the early stages of Rheumatoid Arthritis. Ultrasound (US) provides an indirect method of assessing synovial blood flow and has been shown to correlate with clinical disease activity in patients with Rheumatoid Arthritis. This study examines the relationship of US determined synovitis with synovial vascularity, angiogenic / lymphangiogenic factors and cellular mediators of inflammation in a cohort of patients with early Rheumatoid Arthritis (RA) patients prior to therapeutic intervention with disease modifying therapy or corticosteroids. An ultrasound guided synovial biopsy of the supra-patella pouch was performed in 12 patients with early RA prior to treatment. Clinical, US and biochemical assessments were undertaken prior to the procedure. Ultrasound images and histological samples were obtained from the supra-patella pouch. Histological samples were stained for Factor VIII and a-SMA (a-smooth muscle actin). Using
A detailed abdominal ultrasound examination was performed in five normal horses, repeated on five occasions (total of 25 examinations). The abdomen was divided into ten different imaging sites, and structures identified in each site were recorded. Five imaging sites were then selected for a single focused ultrasound examination in 20 normal horses. Limited patient preparation was performed. Structures were recorded as identified if ultrasonographic features could be distinguished. The location of organs and their frequency of identification were recorded. Data from both phases were analysed to determine repeatability of identification of structures in each examination (irrespective of imaging site), and for each imaging site ...
Background/Purpose: Salivary gland ultrasonography is a highly specific tool for the diagnosis of primary Sjögren´s syndrome (PSS). Real time sonoelastography (RTS) is a novel imaging option involving tissue stiffness assessment. Previous works have reported higher RTS values in PSS vs healthy and sicca controls. Herein we evaluated the stiffness of parotid and submandibular glands using RTS and correlated it with a multiparametric approach including morphologic ultrasonographic parameters, profibrotic chemokines and cytokines levels, serology and the presence of minor salivary gland fibrosis. Methods: We included 26 patients with PSS according to the AECG criteria, who had a salivary gland biopsy with no more than 5 years previous the ultrasonographic evaluation. B-Mode ultrasonography and RTS (ARFI methodology) were performed by a trained radiologist. Parotid and submandibular glands were individually rated for parenchymal echogenicity, homogeneity, hypo-echogenic areas, hyper-echogenic ...
Tumors in the salivary glands or surrounding areas may be investigated by a variety of techniques, including CT, MRI, and US. The selection of specific examinations should be made in consultation with a radiologist. In many institutions, CT is the procedure of choice for evaluating the salivary glands and particularly the extent of a mass since glandular tissue usually can be readily distinguished from surrounding fat and muscle. MRI, however, may better delineate the internal structure of the tumor and demonstrate extension into adjacent tissues. Ultrasonography has typically been used to differentiate solid lesions from cystic lesions in the salivary glands, but recent studies have begun to look more closely at the ultrasonographic features of various salivary tumors in an effort to aid the differential diagnosis by using a noninvasive and relatively inexpensive technique.For many years, sialography has been considered the gold standard for evaluating the salivary component of autoimmune ...
In this presentation, disorders such as intussusception, mechanical ileus, inflammatory bowel conditions, ulceration, and dehiscence are described. All these conditions along with the differential diagnoses are discussed in light of the clinical context and other available imaging modalities.. Intussusception. The main ultrasonographic feature of an intussusception is the multilayered appearance of the wall (concentric rings) representing the wall layers of the intussusceptum and intussuscipiens. The pattern varies somewhat with the length of the bowel segment involved, the duration of the process and the orientation of the scan plane relative to the axis of the intussusception. The intussuscipiens (outer bowel segment) is often edematous and hypoechoic, whereas the intussusceptum may appear normal in thickness and layering. The invaginated bowel can also be associated with invaginated mesenteric fat, inflammatory pseudocysts, enlarged lymph nodes or occasionally tumors in older ...

the mainstay of treatment of polymyalgia rheumatica (PMR) is oral glucocorticoids, but randomized controlled trials of treatment are lacking. As a result, there is no evidence from controlled studies on the efficacy of different initial doses or glucocorticoid tapering. The aim of this study is to test if 12.5 mg prednisone/day is an adequate starting dose in PMR and to evaluate clinical predictors of drug response. 60 consecutive PMR patients were treated with a starting dose of 12,5 mg/day prednisone. Clinical, laboratory, and, in a subset of 25 patients, ultrasonographic features were recorded as possible predictors of response to prednisone. Remission was defined as disappearance of at least 75% of the signs and symptoms of PMR and normalization of ESR and CRP within the first month, a scenario allowing steroid tapering. 47/60 (78.3%) patients responded to 12.5 mg of prednisone after a mean interval of 6.6 ± 5.2 days. In univariate analysis, body weight and gender discriminated the two groups. In
A progressive decline in circulating androgens was observed with advancing age. Patients 21-30 years old had lower plasma glucose and insulin levels, lower area under the oral glucose tolerance test curve and lower homeostasis model assessment of insulin resistance index, and higher glucose/insulin and quantitative insulin sensitivity check index than patients 31-39 years old. The prevalence of PCOS phenotypes changed with age. More specifically, the distribution of the phenotypes did not differ substantially between patients ≤20 years old and patients 21-30 years old. However, a decline in the prevalence of phenotype 1 (characterized by anovulation, hyperandrogenemia, and polycystic ovaries) and an increase in the prevalence of phenotype 4 (characterized by anovulation and polycystic ovaries without hyperandrogenemia) were observed in patients 31-39 years old..
