Clinicopathologic conference: Multiquadrant expansile fibro-osseous lesion in a juvenile
2011
This paper intends to present clinical, radiologic, and histopathologic features of a case of gigantiform cementoma manifesting in a 14-year-old boy, without any familial involvement. He has been followed for 3 years. Further cases from the literature have been reviewed that confirm a similar clinicopathologic picture. This is the first case report that describes "non-familial gigantiform cementoma" after the World Health Organisation's classification of 2005.
Matrical carcinoma with prominent melanocytic hyperplasia (malignant melanocytic matricoma?) A report of two cases.
2003
Melanocytic matricoma is a recently described lesion characterized by well-circumscribed nodules composed of matrical and supramatrical cells with clustered ghost cells, and admixed pigmented dendritic melanocytes, with no cyst formation or connection to the epidermis or pre-existing hair follicles. Although variable cytologic atypia and frequent mitoses in the epithelial component may be present, given the well-defined margins and absence of tumor recurrences, these lesions were initially considered benign neoplasms, and not matrical carcinoma. Theoretically, the detection of numerous melanocytes in matrical carcinoma should not be surprising, but is in fact a very unusual feature. A case …
How to treat tumefactive demyelinating disease?
2013
Glioma-like inflammatory demyelinating lesions can be found in patients with pre-diagnosed multiple sclerosis, but they have also been described as an isolated disease entity. The initial diagnostic work-up usually includes a biopsy for histopathological analysis. However, even after unambiguous histopathologic classification, tumefactive lesions pose a therapeutic challenge. Until now, there have been no guidelines on how to treat patients with these rare and extreme lesion phenotypes. Here we report a patient with a relapsing unifocal tumefactive demyelinating lesion. The patient initially showed a good response to steroid treatment, with full clinical recovery. However, after relapse of…
Impact of oral mucosa lesions on the quality of life related to oral health. An etiopathogenic study
2016
Background To assess the impact of oral mucosa lesions on quality of life related to oral health (QLROH) and additionally to establish whether the etiopathogenicy of oral lesion is associated to the degree of QLROH impact. Material and Methods In this cross-sectional study performed on a non-probability sample of 247 consecutively patients attending the oral medicine and pathology clinic the Spanish version of Oral Health Impact Profile-49 questionnaire (OHIP-49-mx) was applied. Responses were recorded on Likert-type scale whose values ranged from 0 (never) to 4 (always). Values greater than the 50 percentile (median) were considered as indicative of poor quality of life. All patients were …
Influence of vessel dilatation on restenosis after successful percutaneous transluminal coronary angioplasty.
1996
The aim of this study was to evaluate the influence of vessel dilation on restenosis after successful percutaneous transluminal coronary angioplasty (PTCA) on the basis of quantitative angiographic analysis. To have the best comparison possible, we restrospectively studied a homogenous series of patients from the early 1980s treated according to a standardized PTCA procedure. The study group consisted of 86 patients with stable angina pectoris and single-vessel disease, all of whom underwent successful PTCA for a short concentric lesion in proximal vessel parts. The overall restenosis rate was 27%. Angiographically measured balloon size remained below specifications. The size of the inflate…
A novel 3-d reconstruction system for the assessment of bifurcation lesions treated by the mini-crush technique.
2010
Background: Conventional two-dimensional angiography lacks the ability to properly image the true bifurcation geometry, and its percutaneous coronary intervention-induced changes in the clinical setting. Methods and Results: A novel three-dimensional reconstruction system was investigated by retrospectively analyzing 39 lesions in 35 consecutive patients with coronary bifurcation disease treated with the mini-crush technique. At baseline, significant correlations were proved between two- and three-dimensional systems in terms of either reference vessel diameter (R 2 = 0.68 and 0.29 for main and side branches, respectively), minimum lumen diameter (R 2 = 0.73 and 0.36), stenosis diameter (R …
Percutaneous angioplasty and stenting of left subclavian artery lesions for the treatment of patients with concomitant vertebral and coronary subclav…
2006
bjective: To evaluate the efficacy of subclavian stenosis percutaneous transfemoral angioplasty (PTA)-treatment in patients with intermittent or complete subclavian steal syndrome (SSS), and coronary-subclavian steal syndrome (C-SSS) after left internal mammary artery-interventricular anterior artery (LIMA-IVA) by pass graft. Methods: We studied 42 patients with coronary subclavian steal syndrome subdivided in two groups; the first group consisted of 15 patients who presented an intermittent vertebral-subclavian steal, while the second group consisted of 27 patients with a complete vertebral-subclavian steal. All patients were treated with angioplasty and stent application and were followed…
Running-induced muscle injury and myocellular enzyme release in rats
1994
The relationships and time course of exercise-induced muscle damage, estimated by beta-glucuronidase activity and microscopy, to muscle swelling, estimated by muscle water content and microscopy, and to the serum activity of creatine kinase (CK) and the concentration of carbonic anhydrase III were studied in rats 2, 12, 48, and 96 h after 90 min of intermittent running uphill (+13.5 degrees) or downhill (-13.5 degrees) at a speed of 17 m/min. The injury was more pronounced in soleus after uphill running and in the red parts of quadriceps femoris and in the white part of vastus lateralis after downhill running, whereas triceps brachii was not damaged. Increase in muscle water content preced…
Cyberknife radiosurgery for cranial plasma cell tumor
2014
Cranial and intracranial involvement by myelomatous disease is relatively uncommon. Furthermore, systemic manifestations of multiple myeloma are present in the majority of these cases at the time of symptom onset. The authors report the case of a patient with serial appearance of multiple intracranial plasma cell tumor localizations as the first manifestations of a multiple myeloma. The patient was treated with CyberKnife radiosurgery for a lesion localized at the clivus and sella turcica with complete local control. With such a technique, based on high-dose conformality, the tumor was centered with an ablative dose of radiation and, at the same time, with a low dose spreading to the surrou…
Plasma sublimation for the treatment of xanthelasma palpebrarum
2020
Introduction Xanthelasma palpebrarum (XP) is a common xanthomatous lesion of the eyelid and periorbital skin. Several methods of treatment have been reported in the literature, each having its own indications and risks. We present a new treatment method for removing XP using a plasma exeresis device (Plexr®, GMV, Italy). Methods Fifteen patients with a total of 27 treated XPs were assessed and clinically identified by the treating dermatologist. Patients were photographed and assessed by a dermatologist prior to and immediately after treatment. A patient survey was conducted 12 months after the procedure, which assessed the outcome of the procedure (redness, pigmentation disorders, and scar…
