Evaluation of the relationship between COVID-19 pneumonia severity and pulmonary artery diameter measurement.

The goal of the present work was to examine associations between COVID-19 pneumonia severity and pulmonary artery diameter. A total of 101 patients with COVID-19 were included in this retrospective observational study. The patients were divided into three groups based on the CT images: 41 patients with mild pneumonia, group 2 had 39 patients with moderate pneumonia, and group 3 had 21 patients with severe pneumonia.

Hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformations.

Pulmonary arteriovenous malformations (PAVM) are generally congenital lesions caused by abnormal capillary development. Lesions can be in the form of isolated anomaly or as part of autosomal dominantly inherited hereditary hemorrhagic telengiectasia (HHT). HHT is the most common hereditary vascular disease characterized by mocucutaneuos telengiectasia and visceral arteriovenous malformations.

Review of Hydatid Cyst with Focus on Cases with Unusual Locations.

Objective: This study has been conducted so as to contribute to health statistics of hydatid cyst by the data obtained from our clinic, and to discuss hydatid cysts in unusual locations.

Material And Method: Cases diagnosed as hydatid cyst at Dr. Lutfi Kirdar Kartal Research and Education Hospital Pathology Clinic between 2007 and 2015 have been evaluated based on criteria such as age, sex and location.

Association of endogenous melatonin with uric acid and traditional cardiovascular risk factors in healthy young male.

Background: Uric acid may act as an antioxidant; high serum uric acid levels are often associated with cardiovascular disease, such as coronary artery disease. Melatonin plays a role as a direct free radical scavenger and indirect antioxidant. No study has examined the relationships between endogenous melatonin and uric acid in order to predict the risk of future cardiovascular disease in males so far.

Assessment of carotid body tumor and its association with tetralogy of fallot: effect of the chronic hypoxia.

This is a rare combined presentation of Tetralogy of Fallot and carotid body tumor (CBT). Hypotheses and further discussion provides data for the development of CBT as a response to chronic hypoxemia. This present study demonstrates and discusses such an occurrence.

Association of Mitral Annular Calcification with Left Ventricular Mechanics: A Speckle Tracking Study.

Background: Mitral annular calcification (MAC) is a common echocardiographic finding in clinical practice and is associated with cardiovascular risk factors and atherosclerosis. However, data regarding left ventricular (LV) functions are lacking. We aimed to evaluate the relationship between MAC and LV mechanical functions with the utility of two-dimensional speckle tracking echocardiography (2DSTE).

Acute effects of ultrafiltration on aortic mechanical properties determined by measurement of pulse wave velocity and pulse propagation time in hemodialysis patients.

Objective: The effects of acute hemodialysis session on pulse wave velocity are conflicting. The aim of the current study was to assess the acute effects of ultrafiltration on the aortic mechanical properties using carotid-femoral (aortic) pulse wave velocity and pulse propagation time.

Methods: A total of 26 (12 women, 14 men) consecutive patients on maintenance hemodialysis (mean dialysis duration: 40.

Primary cutaneous angiosarcoma on the nose in a patient with multiple nonmelanoma skin cancers.

Cutaneous angiosarcoma is an uncommon, potentially metastatic and highly aggressive vascular tumor that may arise as de novo or be associated with previous radiotherapy. A 70-year-old female with a solitary lesion on the nose was initially diagnosed as actinic keratosis. However, when the recurring lesion at the same region within 6 months was reexcised, the histological diagnosis was definitively established as well-differentiated angiosarcoma.

Triple antiplatelet therapy after PCI--should or could it be done?

In case of coronary stenting in patients taking long-term oral anticoagulants (OAC), addition of both aspirin and clopidogrel in the drug regimen (so-called triple antiplatelet therapy) is recommended. However such triple therapy increases the risk of serious bleeding events. Comparative data on the efficacy and safety of the triple therapy versus therapy with a single antiplatelet agent and oral anticoagulants in case of coronary stenting are very rare.

Necrotizing fasciitis of the perineum.

Background: Necrotizing fasciitis is a severe soft tissue infection characterized by rapidly progressing necrosis, involving subcutaneous tissues. This rare condition carries a high mortality rate and requires prompt diagnosis and urgent treatment with radical debridement and antibiotics; but early diagnosis, which is essential to successful treatment, remains a challenge.

Methods: Physical examination findings, preoperative and operative findings, histopathological results of the structure, and follow-up results of the patient are discussed with related reports.

The relationship of COX-2 expression with estrogen receptor, progesterone receptor and prognostic parameters in endometrial carcinomas.

Aim: Endometrial cancer (EC), which is the most common gynecologic cancer, develops as a result of disruption of the delicate balance between cell proliferation and cell loss, or apoptosis through activation of oncogenesis, or loss of tumor suppressor genes. Among the biochemical factors proposed to give a more detailed characterization of EC biology, estrogen receptors (ER) and progesterone receptors (PR) play a major role. Most of the studies in the literature have shown increased expression of cyclooxygenase-2 (COX-2) in EC.

The relationship of cerb B 2 expression with estrogen receptor and progesterone receptor and prognostic parameters in endometrial carcinomas.

Background: Endometrial carcinoma (EC) is the most common malignancy of the female genital tract. Gene alterations and overexpression of various oncogenes are important in tumor development. The human HER 2 neu (c-erbB-2) gene product is a transmembrane receptor with an intracellular tyrosine kinase that plays an important role in coordinating the endometrial growth factor receptor signaling network.

Arterial distensibility in Wegener's granulomatosis: a carotid-femoral pulse wave velocity study.

Objective: The purpose of this study was to test the hypothesis; that chronic inflammation may impair vascular function and lead to an increase of arterial pulse wave velocity (PWV) in patients with Wegener's granulomatosis (WG).

Methods: We recruited 5 patients with WG and 5 healthy age and sex matched controls in this cross-sectional case-controlled study. Aortic PWV was determined by using an automatic device (Complior Colson, France), which allowed on-line pulse wave recording and automatic calculation of PWV.
