The Effect of Vitamin D Supplement on the Relapsing Incidence of Rhinosinusitis with Nasal Polyposis after Fuctional Endoscpoic Sinus Surgery.

Background: Nasal polyp (NP) is the most common benign tumor that can cause nasal obstruction and more annoying problems in patients. Recently, investigators have been focusing on complementary therapies alone or in conjunction with endoscopic nasal and sinus surgery. However, given the association of Vitamin D (VD) deficiency and chronic rhinosinusitis with nasal polyposis (CRSwNP) in previous studies, it may be possible to prevent the recurrence of NP and the development of rhinosinusitis by controlling serum levels of VD and maintaining it at a normal level.

Patient's Dignity: Viewpoints of Patients and Nurses in Hospitals.

Much of the available research on perceptions of patient dignity either is qualitative in type or explores them in specific patient groups, such as elderly patients, cancer patients, terminally-ill patients, and adolescent patients. The present study addresses nurses' and adult patients' views on patient dignity. A total of 400 individuals (200 nurses and 200 patients) from 39 internal and surgical units from four hospitals affiliated to Shiraz University of Medical Sciences participated in the study.

Exploration, antifungal and antiaflatoxigenic activity of halophilic bacteria communities from saline soils of Howze-Soltan playa in Iran.

In the present study, halophilic bacteria communities were explored in saline soils of Howze-Soltan playa in Iran with special attention to their biological activity against an aflatoxigenic Aspergillus parasiticus NRRL 2999. Halophilic bacteria were isolated from a total of 20 saline soils using specific culture media and identified by 16S rRNA sequencing in neighbor-joining tree analysis. Antifungal and antiaflatoxigenic activities of the bacteria were screened by a nor-mutant A.

Classification of pulmonary system diseases patterns using flow-volume curve.

Spirometry is the most common pulmonary function test. It provides useful information for early detection of respiratory system abnormalities. While decision support systems use normally calculated parameters such as FEV1, FVC, and FEV1% to diagnose the pattern of respiratory system diseases, expert physicians pay close attention to the pattern of the flow-volume curve as well.
