Clinico-therapeutic management of osteoradionecrosis: A literature review and update

2010

In the management of head and neck cancer, radiotherapy is usually a coadjuvant to surgery, or is applied on a palliative basis. The most important complication of such radiotherapy is osteoradionecrosis, which manifests as an area of exposed necrotic bone in the maxillae or mandible that fails to heal during at least three months. In most cases osteoradionecrosis gradually progresses, becoming more extensive and painful, and its late manifestations comprise infection and pathological fracture. The present study provides a literature review and update on the risk factors underlying osteoradionecrosis, its clinical and diagnostic particulars, prevention, and most widely accepted treatment op…

Fusion of the 1H NMR data of serum, urine and exhaled breath condensate in order to discriminate chronic obstructive pulmonary disease and obstructiv…

2015

Chronic obstructive pulmonary disease, COPD, affects the condition of the entire human organism and causes multiple comorbidities. Pathological lung changes lead to quantitative changes in the composition of the metabolites in different body fluids. The obstructive sleep apnea syndrome, OSAS, occurs in conjunction with chronic obstructive pulmonary disease in about 10–20 % of individuals who have COPD. Both conditions share the same comorbidities and this makes differentiating them difficult. The aim of this study was to investigate whether it is possible to diagnose a patient with either COPD or the OSA syndrome using a set of selected metabolites and to determine whether the metabolites t…

Metabolomics of chronic obstructive pulmonary disease and obstructive sleep apnea syndrome : response to Maniscalco and Motta

2016

We appreciate Maniscalco and Motta’s comments on our recently published article “Fusion of the 1H NMR data of serum, urine and exhaled breath condensate in order to discriminate chronic obstructive pulmonary disease and obstructive sleep apnea syndrome” (Zabek et al. 2015) and we are grateful for the opportunity to clarify a number of points from our work. We are glad that the authors appreciated our data analysis and interpretation. Fusion of metabolomic data is an outstanding tool for a comprehensive description of patient’s phenotype that combines metabolic profiles acquired in different domains. Such an integrative approach is highly valued in the so-called ‘breathomics’ (Smolinska et a…

Inflammatory mediators as biomarkers in brain disorders.

2013

Neurodegenerative diseases such as Alzheimer, Parkinson, amyotrophic lateral sclerosis, and Huntington are incurable and debilitating conditions that result in progressive death of the neurons. The definite diagnosis of a neurodegenerative disorder is disadvantaged by the difficulty in obtaining biopsies and thereby to validate the clinical diagnosis with pathological results. Biomarkers are valuable indicators for detecting different phases of a disease such as prevention, early onset, treatment, progression, and monitoring the effect of pharmacological responses to a therapeutic intervention. Inflammation occurs in neurodegenerative diseases, and identification and validation of molecules…

The objective of this cross-sectional and retrospective cohort study was (1) to determine the usefulness of intima-media thickness (IMT) in contrast to plaque assessment, (2) to examine the value of additive femoral artery sonography and (3) to identify potential risk factors for atherosclerosis and incident cardiovascular events in systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) patients. In this study, 90 SSc and 100 SLE patients were examined by duplexsonography. IMT was measured in common carotid and common femoral arteries, plaques were assessed in common, internal and external carotid and common, proximal superficial and deep femoral arteries. Different definitions of …

The histology and immunohistochemistry of free buccal mucosa and full-skin grafts after exposure to urine

1999

Objective To investigate the histological and immunohistochemical behaviour of free buccal mucosa and full-skin grafts after exposure to urine. Materials and methods A buccal mucosal graft and a full-skin graft were freely transferred into the bladder of 12 minipigs, after stripping the bladder mucosa. Endoscopic investigations were carried out 2 and 5 months after surgery, and the grafts examined after death at 7 months, both histologically and immunohistochemically. Results Shrinkage of the full-skin graft was apparent endoscopically in five cases. Of the nine full-skin grafts, four showed severe inflammatory reactions, two necrosis and two ulcerations. Conversely, the 10 buccal mucosal g…

Oral pigmented lesions: clinicopathologic features and review of the literature

2012

Diagnosis of pigmented lesions of the oral cavity and perioral tissues is challenging. Even though epidemiology may be of some help in orientating the clinician and even though some lesions may confidently be diagnosed on clinical grounds alone, the definitive diagnosis usually requires histopathologic evaluation. Oral pigmentation can be physiological or pathological, and exogenous or endogenous. Color, location, distribution, and duration as well as drugs use, family history, and change in pattern are important for the differential diagnosis. Dark or black pigmented lesions can be focal, multifocal or diffuse macules, including entities such as racial pigmentation, melanotic macule, melan…

Pathologist’s Findings after PTCA (The Mechanism of Angioplasty)
