Aim: We aimed to determine the potential of CD10 as a marker for the early diagnosis of adenocarcinoma of the colon.

Background: Adenocarcinoma is diagnosed in one out of 20 individuals in the USA and western European countries. Its prognosis and treatment depend largely on the severity of the disease at the time of diagnosis.

Immunogenetic, Molecular and Microbiotic Determinants of Eosinophilic Esophagitis and Clinical Practice-A New Perspective of an Old Disease.

Eosinophilic oesophagitis (EoE) is a chronic, allergic disease associated with a T-lymphocyte response inducing esophageal eosinophilic infiltration in the esophagus. Inflammation and tissue fibrosis are responsible for the main clinical symptoms such as food impaction and dysphagia. The etiopathogenesis is multifactorial in which genetic and environmental factors coexist.

Home parenteral nutrition a life-saving therapy in a primary intestinal lymphangiectasia patient affecting the entire GI tract - 3 year follow-up case report.

Introduction And Importance: Primary intestinal lymphangiectasia (PIL) is a rare protein-losing gastroenteropathy of unknown etiology, characterized by impaired lymphatic vessels drainage. The pathological changes in PIL result in usually localized or diffuse dilatation of intestinal lacteals, leading to leakage of lymphatic fluid rich of proteins, lymphocytes, and immunoglobulins into the intestinal lumen. PIL may be asymptomatic or mildly symptomatic in moderate forms of the disease.

Peripheral T-Cell Lymphoma Possibly Due to Unrecognized Celiac Disease in an Elderly Patient: A Case Report.

Celiac disease (CD) is widely perceived as a childhood disorder. However, it has been demonstrated that 19-34% of new CD cases are diagnosed in patients over 60 years of age and lack the typical presentation. A 76-year-old female was admitted to the clinic due to a recurrent fever that had lasted over a year accompanied by progressive weakness, weight loss of about 10 kg, dehydration, and malnutrition.

Skull base trauma: Masking, stimulating or neutral factor for the insidious development of angiosarcoma in a 19-year-old.

Angiosarcoma is a malignancy of endothelial tumor and represents 1-2% of all soft tissue sarcomas, uncommonly found in the head and neck region. The etiology is not clear but there are definite risk factors including chronic lymphoedema, history of radiation, environmental carcinogens and certain familial syndromes. Presented here is a case of a patient treated due to the skull base trauma and diagnosed with this type of tumor.

Usefulness of rebiopsy in the case of mesangial pathology.

Immunologically different types of glomerulopathies show varied symptoms and clinical courses. Unlike in lupus nephritis, repeated biopsy is rarely performed in cases of mesangial glomerulonephritis. We reviewed 200 cases wherein rebiopsy was performed in patients with diagnosed mesangial glomerular pathology over a 30-year period and analyzed the symptoms follow-up in these cases.

Transcriptomic Profile of Genes Encoding Proteins Involved in Pathogenesis of Sjögren's Syndrome Related Xerostomia-Molecular and Clinical Trial.

Sjögren's syndrome (SS) is characterized by xerostomia. We aimed to investigate and compare gene expressions in the labial salivary glands of SS patients with xerostomia SS (sicca) and without xerostomia SS (non-sicca) and of healthy subjects (HS) by means of microarray analysis, and to find genes involved in xerostomia. The study group comprised 11 SS patients (3 SS (sicca) and 8 SS (non-sicca)) and 9 HS.

Common sense and tumor treatment. A case of pilomatrical carcinoma in a 21-year-old patient with surprisingly rapid tumor progression.

Pilomatrical carcinoma is a rare tumor originating from skin appendages, usually occurring between the 5th and 7th decade of life. We present a case of an exceptionally young, 21-year-old patient with surprisingly rapid tumor progression and answer the question, what was the reason for such uncontrolled tumor growth. The main concern is the diagnostic challenge and a peculiar, one week race against time and tumor progression so that the least disfiguring surgery could be done.

Early presentation of sympathetic ophthalmia in optical coherence tomography studies: A case report.

Sympathetic ophthalmia (SO) is often diagnosed when an inflammatory process appears to be advanced. Herein, the authors present the prospective optical coherence tomography (OCT) study of the onset of SO in the sympathizing eye. Prior to any signs of uveitis, we noted the mild disintegration of the retinal pigment epithelium (RPE) layer, the interdigitation zone (IZ), and the ellipsoid zone (EZ).

Morphological assessment of thin basement membrane disease.

Thin basement membrane disease is more common than IgA nephropathy or Alport syndrome, which are also associated with the presence of erythrocyturia. Very few reports on the disorder are available in the Polish literature. The objective of this work was to analyze the results from 83 patients with thin basement membrane syndrome as well as to formulate a proposal of strict morphological assessment criteria for the disorder.

The study aimed to assess the influence of anti-tumour necrosis factor (anti-TNF) therapy on the angiogenesis in relation to microscopic and endoscopic healing in CD patients.

Material And Methods: Colonic tissue samples from 17 CD patients were taken during colonoscopy before and after anti-TNF therapy.

Usefulness of Endoscopic Indices in Determination of Disease Activity in Patients with Crohn's Disease.

Background. Assessment of endoscopic activity of Crohn's disease (CD) is of growing importance both in clinical practice and in clinical trials. The study aimed to assess which of the endoscopic indices used for evaluation of mucosal changes correlates with the currently used clinical indices for determination of disease activity and with the results of histopathological examination.

Integrated genomic DNA/RNA profiling of hematologic malignancies in the clinical setting.

The spectrum of somatic alterations in hematologic malignancies includes substitutions, insertions/deletions (indels), copy number alterations (CNAs), and a wide range of gene fusions; no current clinically available single assay captures the different types of alterations. We developed a novel next-generation sequencing-based assay to identify all classes of genomic alterations using archived formalin-fixed paraffin-embedded blood and bone marrow samples with high accuracy in a clinically relevant time frame, which is performed in our Clinical Laboratory Improvement Amendments-certified College of American Pathologists-accredited laboratory. Targeted capture of DNA/RNA and next-generation sequencing reliably identifies substitutions, indels, CNAs, and gene fusions, with similar accuracy to lower-throughput assays that focus on specific genes and types of genomic alterations.

Applicability of endoscopic indices in the determination of disease activity in patients with ulcerative colitis.

Objective: The combination of clinical remission and mucosal healing represents a major goal of different treatment strategies for ulcerative colitis (UC). This study aimed to assess which of the endoscopic indices used to evaluate mucosal changes in UC are correlated with clinical indices currently used to determine disease activity, as well as which of the endoscopic indices are correlated with the Geboes Index used for histological evaluation. It also aimed to find correlations between the currently used clinical activity indices and the histological Geboes Index.

Squamous cell lung cancer in a male with pulmonary tuberculosis.

Lung cancer and pulmonary tuberculosis (TB) are highly prevalent and representing major public health issues. They share common risk factors and clinical manifestations. It is also suggested that TB predicts raised lung cancer risk likely related to chronic inflammation in the lungs.

Supplementary chromium(III) propionate complex does not protect against insulin resistance in high-fat-fed rats.

Improper eating habits such as high-fat or high-carbohydrate diets are responsible for metabolic changes resulting in impaired glucose tolerance, hyperinsulinemia, insulin resistance, and ultimately diabetes. Although the essentiality of trivalent chromium for humans has been recently questioned by researchers, pharmacological dosages of this element can improve insulin sensitivity in experimental animals and diabetic subjects. The aim of the study was to assess the preventive potential of the supplementary chromium(III) propionate complex (CrProp) in rats fed a high-fat diet.

Anti-TNF antibodies do not induce the apoptosis of lamina propria mononuclear cells in uninflamed intestinal tissue in patients with Crohn's disease.

It is not known if anti-tumor necrosis factor (anti-TNF) agents provoke only apoptosis of lamina propria mononuclear cells (LPMC) engaged in inflammatory processes or whether it's a general phenomenon concerning all LPMC. In this study we carried out an immunohistochemical analysis of the expression of several apoptosis-related proteins (active caspase-3, Bax, Bcl-2, Fas, TNFR1, CD4, and CD8) in uninflamed mucosa in Crohn's disease (CD) patients treated with anti-TNF agents. 16 CD patients (mean age 34 ± 11, mean disease duration 7 ± 5 years) were included in the study.

Development and validation of a clinical cancer genomic profiling test based on massively parallel DNA sequencing.

As more clinically relevant cancer genes are identified, comprehensive diagnostic approaches are needed to match patients to therapies, raising the challenge of optimization and analytical validation of assays that interrogate millions of bases of cancer genomes altered by multiple mechanisms. Here we describe a test based on massively parallel DNA sequencing to characterize base substitutions, short insertions and deletions (indels), copy number alterations and selected fusions across 287 cancer-related genes from routine formalin-fixed and paraffin-embedded (FFPE) clinical specimens. We implemented a practical validation strategy with reference samples of pooled cell lines that model key determinants of accuracy, including mutant allele frequency, indel length and amplitude of copy change.

Ki-67 and p53 expression in ileal pouches.

Development of dysplastic lesions that may potentially lead to cancer is sometimes reported within the ileal pouches. Dysplasia is in turn associated with increased expression of proliferation indices. The goal of this study was to evaluate the mitotic activity and possible expression of p53 in the epithelium within the ileal pouches in patients with chronic ulcerative colitis.
