Case Report: Skeletal Muscle Lymphoma as a Result of Slow Centrifugal Migration of Untreated Primary Neurolymphomatosis?

Introduction: Fludeoxyglucose (F) (FDG) hybrid positron emission tomography/computed tomography (PET/CT) is currently a well-documented tool for diagnosis, staging, and therapeutic follow-up of lymphoma with significant impact on therapeutic decisions.

Patient Concerns And Interventions: We reported a case of a 71-year-old woman with diffuse large B-cell lymphoma (DLBCL) of the left gluteal muscles as a possible result of slow centrifugal migration of untreated neurolymphomatosis (NL) of the lumbosacral plexus suggested on FDG PET/CT 4 years ago, when the patient was complaining for weakness and numbness of the left leg, but the proposed biopsy of peripheral nerve was not performed. Four years later, no pathological FDG uptake was present in nerves and lymph nodes, but PET/CT detected multiple FDG-positive infiltrates in the left gluteal muscles, appearing as a continuation of previously involved nerves.

Interference of Known or Suspected Endometriosis in Reporting FDG PET/CT Performed in Another Indication.

Introduction: Endometriosis is a common gynecologic condition that may be visualized on 18F-FDG PET/CT and mimic lesions of malignancy. We analyzed the interference of known or suspected endometriosis in reporting 18F-FDG PET/CT performed in another indication.

Results: The PET/CT images of 18 women with known (n = 15) or suspected (n = 3) endometriosis were analyzed.

Identification of Whole-Serum Glycobiomarkers for Colorectal Carcinoma Using Reverse-Phase Lectin Microarray.

Colorectal cancer (CRC) is one of the most common types of cancer among men and women worldwide. Efforts are currently underway to find novel and more cancer-specific biomarkers that could be detected in a non-invasive way. The analysis of aberrant glycosylation of serum glycoproteins is a way to discover novel diagnostic and prognostic CRC biomarkers.

Diagnostic reliability of nested PCR depends on the primer design and threshold abundance of Helicobacter pylori in biopsy, stool, and saliva samples.

Background: The aim of this work was to find a reliable nested PCR for the detection of Helicobacter pylori in biopsy, stool, and saliva specimens.

Materials And Methods: Novel nested PCR was elaborated and validated on 81 clinical biopsy, stool, and saliva samples from the same individual and compared to available H pylori assays: histology, rapid urease test (RUT), stool antigen test (SAT), C-urea breath test (UBT).

Results: The efficiency and selectivity of 17 published nested polymerase chain reactions (PCR) available for Helicobacter pylori detection were re-evaluated.

[Mesenterointestinocolonovascular arterial ischemic disease: guidelines of the angiology section of Slovak Medical Chamber (AS SMC, 2013)].

Organovascular arterial ischemic diseases (cardiovascular, cerebrovascular, extremitovascular, renovascular, genitovascular, pulmovascular, mesenterovascular, dermovascular, oculovascular, otovascular, stomatovascular etc.) are an important manifestations of systemic atherosclerosis and other arterial diseases of vascular system (arteriolosclerosis/arteriolonecrosis; diabetic macroangiopathy; diabetic microangiopathy; Mönckeberg´s mediosclerosis/mediocalcinosis; arteritis - vasculitis; syndromes of arterial compression; fibromuscular dysplasia; cystic adventitial degeneration; arterial thrombosis; arterial embolism/thromboembolism; traumatic and posttraumatic arteriopathies; physical arteriopathies; chemical and toxic arteriopathies; iatrogenic arterial occlusions; dissection of aorta and of arteries; coiling; kinking; complicated arterial aneurysms; arteriovenous fistula, rare vascular diseases). Key clinical-etiology-anatomy-pathophysiology (CEAP) aspects of the mesenteriovascular arterial ischemic diseases are discussed in this article (project Vessels).

Novel MLH1 and MSH2 germline mutations in the first HNPCC families identified in Slovakia.

Hereditary nonpolyposis colorectal cancer (HNPCC) is a dominantly-inherited cancer predisposition syndrome, in which the susceptibility to cancer of the colon, endometrium and ovary is linked to germline mutations in DNA mismatch repair (MMR) genes. We have recently initiated a cancer prevention program in suspected HNPCC families in the Slovak Republic. The first ten families fulfilling Amsterdam criteria or Bethesda guidelines were screened for germline mutations in MLH1 and MSH2, two MMR genes most frequently mutated in HNPCC families.

Collagen type IV in epithelial tumours of colon.

Collagen type IV in the lamina propria mucosae is one of the main components of the basement membrane of normal and transitional colon mucosa. The aim of the present study was to assess the use of anti-collagen type IV antibodies in the evaluation of biological activity of epithelial tumours of the colon. Formalin-fixed and paraffin-embedded specimens of polyps and carcinomas of the colon from 14 patients were analyzed.
