Recurrent and More Severe COVID-19 Infection: Two Elderly Case Reports.

Although the sensitivity of reverse transcriptase-polymerase chain reaction (RT-PCR) is low in the diagnosis of coronavirus disease 2019 (COVID-19), it is the gold standard. Clinical improvement is prioritized in the follow-up of patients with COVID-19 who are followed as possible or definitive cases. Although the priority in the discharge decision is the resolution of complaints, it is also important to see radiological improvement and RT-PCR negativity.

A retrospective evaluation of the pulmonary function tests and quality of life assessment surveys of emphysema patients subject to coil treatment.

Introduction: Bronchoscopic volume reduction treatments are among the important alternatives for selected emphysema patients with a dyspneic course despite optimal medical treatment. Our aim was to carry out a retrospective scan of the data for COPD patients subject to coil treatment at our center for assessing whether coil procedure has an impact on the respiratory symptom and pulmonary function tests in COPD patients.

Materials And Methods: The data of 41 patients with severe emphysema and treated with coils between 2017-2020 were evaluated retrospectively.

The Effects of Endobronchial Coil Therapy on Right Ventricular Functions.

Lung hyperinflation is an important therapeutic target in symptomatic emphysema patients. Endobronchial therapies that reduce end-expiratory lung volume are increasingly being used in advanced cases. However, there is paucity of data regarding the effects of these therapies on the heart functions.

Evaluation of disease severity with quantitative chest CT in COVID-19 patients.

Purpose: We aimed to assess the severity of coronavirus disease 2019 (COVID-19) pneumonia on computed tomography (CT) using quantitative (QCT) and semiquantitative (SCT) assessments and compare with the clinical findings.

Methods: Two observers independently examined the CT images of COVID-19 patients, and the SCT severity score was calculated. The SCT score was calculated as the sum of values ranging from 0 to 4, according to the volumetric rate of involvement for each lung lobe.

Benign Paroxysmal Positional Vertigo in Pregnancy.

Benign paroxysmal positional vertigo (BPPV) is a clinical entity characterized by acute, brief paroxysmal attacks of rotational vertigo induced by head position changes. It is the most common peripheral vestibular pathology and is seen more frequently in women. However, to our knowledge, there is very limited data on the association between BPPV and pregnancy in both English and Turkish literature.

Breast cancer and cyclin D1 gene polymorphism in Turkish women.

Background: Cyclin D1 protein plays an important part in regulating the progress of the cell during the G(1) phase of the cell cycle. It has been suggested that G870A polymorphism at the exon4/intron4 splicing region of the CCND1 gene may play a role in tumorigenesis and invasiveness.

Patients And Methods: A case-control study was performed to test the association between G870A polymorphisms in the CCND1 gene and breast cancer risk and cancer progression.

ARE-I polymorphism on PSA gene in prostate cancer patients of a Turkish population.

Background: The gene for kallikrein-like serin protease, prostate-specific antigen (PSA), has been a candidate gene in several studies. It is known that androgens are important in the proliferation and development of prostate gland and they are the main regulators of PSA expression. The polymorphism of the ARE-I locus on the PSA gene was studied in prostate cancer patients to determine a possible relationship of that locus to prostate cancer risk.
