Giant Intrathoracic Mass in a Young Woman With Acute Kidney Injury.

CASE PRESENTATION: A 35-year-old woman without past medical history sought treatment for fatigue and dry cough of 3 weeks' duration. Basic laboratory tests revealed severe anemia. She had no history of bleeding, hemoptysis, dyspnea, or fever. The patient was admitted for RBC transfusion and more extensive diagnostics.

The impact of stress, anxiety and depression on stomatognathic system of physiotherapy and dentistry first-year students.

INTRODUCTION: It is well proven that psychoemotional factors play causative role in development of many civilization diseases. Psychosocial stress is effecting with development of certain oral parafunctions like teeth grinding, bruxism, or cheeks biting. Eventually, all of those parafunctional activities may cause increase of masticatory muscles tone and provoke its intensification. Literature indicates that students must cope with greater level of stressful situations than the average representative of the society. METHODS: The research group comprised Ist-year physiotherapy and dentistry students from University School of Physical Education in Wroclaw and Wroclaw Medical University. The study consisted the following: psychological and health questionnaires, and stomatological examination with masseter muscles' electromyography. RESULTS: In intraoral examination, symptoms of parafunctions were more frequently observed in physiotherapy students. The mean tone of masseters was higher also among physiotherapy students. The level of perceived stress was high in both groups, and the experienced borderline and incorrect results in Hospital Anxiety and Depression Scale were more frequently observed in dentistry students. The mean tone of masseter muscle was rising with the level of anxiety in physiotherapy group. Among dentistry, the tendency for rise of masseter muscle tone together with level of anxiety and depression was observed. CONCLUSIONS: Physiotherapy and dentistry beginners differ between each other's by prevalence of temporomandibular disorders (TMD) and oral parafunction symptoms. The level of perceived stress is high in both groups. The level of experienced anxiety and depression is higher in dentistry group. In both study groups, there is significant growth and tendency for simultaneous rise of masseter muscle tone accordingly to stress, anxiety, and depression indicators.

Cytoplasmic HAX1 Is an Independent Risk Factor for Breast Cancer Metastasis.

HAX1 is an antiapoptotic factor involved in the regulation of cell migration and calcium homeostasis, overexpressed in several cancers, including breast cancer. It has been suggested that HAX1 is also implicated in metastasis. Herein we report the results of meta-analysis of HAX1 expression, based on publicly available data, which confirms its significant overexpression in breast cancer and demonstrates copy number gain and prognostic value of HAX1 overexpression for metastatic relapse in ER+ tumors. IHC analysis reported here also reveals its significant overexpression in breast cancer samples from primary tumors, indicating significantly higher HAX1 protein levels in a group of patients who developed distant metastases in a disease course. Moreover, we demonstrate that HAX1 localization is important for the prediction of metastatic relapse and that cytoplasmic but not nuclear HAX1 is an independent risk factor for breast cancer metastasis.

Psychopathological profile and quality of life of patients with oral lichen planus.

Oral lichen planus (OLP) is a chronic, multifocal, sometimes painful, inflammatory disease of the oral mucosa. OLP can predispose development of psycho-emotional disorders. Until now, the relationship between the severity of lichen planus and the psychological profile of patients (psychological well-being, perceived stress and pain coping strategies) has never been studied. Study was conducted on 42 OLP patients. Number of sites involved, severity and activity score of OLP were evaluated. Psychological tests were used to evaluate patients' psycho-emotional condition. The mean duration time of symptomatic OLP was 43 months. We detected that the longer the duration of subjective symptoms, the poorer the quality of life and the higher the level of perceived stress (PSS). Also, the higher the PSS results, the greater the anxiety and depression on Hospital Anxiety and Depression Scale (HADS). Likewise, higher level of depression in HADS was strongly correlated with worse quality of life. (p≤0.05). In this study, we detected a relationship between duration of the disease, level of perceived stress and quality of life. The longer the disease lasts, the higher it tends to catastrophize. This may influence development or increase of the anxiety and depression and may decrease patients' quality of life.

Psychopathological profile and quality of life of patients with oral lichen planus

Abstract Objectives Oral lichen planus (OLP) is a chronic, multifocal, sometimes painful, inflammatory disease of the oral mucosa. OLP can predispose development of psycho-emotional disorders. Until now, the relationship between the severity of lichen planus and the psychological profile of patients (psychological well-being, perceived stress and pain coping strategies) has never been studied. Material and Methods Study was conducted on 42 OLP patients. Number of sites involved, severity and activity score of OLP were evaluated. Psychological tests were used to evaluate patients' psycho-emotional condition. The mean duration time of symptomatic OLP was 43 months. Results We detected that the longer the duration of subjective symptoms, the poorer the quality of life and the higher the level of perceived stress (PSS). Also, the higher the PSS results, the greater the anxiety and depression on Hospital Anxiety and Depression Scale (HADS). Likewise, higher level of depression in HADS was strongly correlated with worse quality of life. (p≤0.05). Conclusions In this study, we detected a relationship between duration of the disease, level of perceived stress and quality of life. The longer the disease lasts, the higher it tends to catastrophize. This may influence development or increase of the anxiety and depression and may decrease patients' quality of life.

Changes in plasma miR-9, miR-16, miR-205 and miR-486 levels after non-small cell lung cancer resection.

PURPOSE: The majority of non-small cell lung cancer (NSCLC) patients presents with an advanced-stage disease and, consequently, exhibits a poor overall survival rate. We aimed to assess changes in plasma miR-9, miR-16, miR-205 and miR-486 levels and their potential as biomarkers for the diagnosis and monitoring of NSCLC patients. METHODS: Plasma was collected from 50 healthy donors and from NSCLC patients before surgery (n = 61), 1 month after surgery (n = 37) and 1 year after surgery (n = 14). microRNA levels were quantified using qRT-PCR. RESULTS: We found in NSCLC patients before treatment, both with squamous cell carcinoma (SQCC) and adenocarcinoma (ADC), significantly higher plasma miR-16 and miR-486 levels than in healthy individuals. Pre-treatment miR-205 concentrations were found to be significantly higher in SQCC than in ADC patients, and only SQCC patients presented significantly higher circulating miR-205 levels than healthy donors. SQCC plasma miR-9 levels were not different from normal control levels, but in ADC they were found to be significantly decreased. A combination of plasma miR-16, miR-205 and miR-486 measurements was found to discriminate NSCLC patients from healthy persons, with a specificity of 95% and a sensitivity of 80%. Following tumor resection, we found that the miR-9 and miR-205 levels significantly decreased, even below the normal level, whereas the increased miR-486 level persisted up to one year after surgery, and the miR-16 level decreased to normal. After tumor resection, none of the miR levels tested was found to relate to recurrence. CONCLUSIONS: Our data indicate that miR-9, miR-16, miR-205 and miR-486 may serve as NSCLC biomarkers. The observed cancer-related pre- and post-operative changes in their plasma levels may not only reflect the presence of a primary cancer, but also of a systemic response to cancer.

Epidermal growth factor receptor (EGFR) status in chordoma.

Chordoma is a rare tumour arising from the embryonal remnants of a notochord occurring most commonly in the sacrococcygeal as well as head and neck locations. Current treatment includes surgery and/or proton beam radiotherapy. In several cases especially in the head and neck location, surgery is not advised. Proton beam therapy is not always effective enough to eradicate the tumour. Additional modes of therapy are needed. One of the current therapeutic approaches in various tumours is targeted therapy and one of the targets is EGFR. The aim of this study was to evaluate EGFR expression and EGFR gene status of chordoma. Twenty-one cases of chordoma were retrieved from the in-house and consultation files of the Maria Sklodowska-Curie Memorial Cancer Centre and Institute of Oncology in Warsaw. Immunohistochemistry with an anti-EGFR antibody and FISH was performed on slides obtained from representative archival paraffin blocks. In our study 81% of cases of chordoma showed low to high EGFR expression in immunohistochemistry. In six cases (26.6%) the FISH results for EGFR were classified as positive (an average EGFR copy number > or = 4 per cell). There was one case of chromosome 7 aneuploidy reported.
