Vitamin D status and blood group among severe COVID-19 patients.

Objective: Prognosis of COVID-19 infection has been indicated to be associated with vitamin D status and ABO blood group. However, owing to discrepancies and an increased number of cases globally, the findings remain unclear. This study aimed to evaluate the association between vitamin D and ABO blood group systems in patients with severe COVID-19.

Paracetamol versus Paracetamol Plus Ondansetron on Acute Postoperative Pain.

This study was performed to determine the comparative efficacy of paracetamol alone versus paracetamol plus ondansetron on acute postoperative pain after abdominal surgeries in Azad University hospitals in 2017 and 2019. In this randomized clinical trial, 62 consecutive patients under abdominal surgeries, were randomly divided into two groups, group 1 patient who received paracetamol alone 1 gram and group 2 patient who received paracetamol 1 gram plus 4 mg ondansetron and the pain severities were determined and compared between groups at recovery and after 4 and 24 hours. The results of this study revealed that there were no statistically significant differences between two groups for the postoperative pain severity and analgesic use ( > 0.

Effect of caffeine on postoperative bowel movement and defecation after cesarean section.

Coffee is reported to have beneficial effects on bowel motility after the surgery. This study is designed to evaluate the effects of coffee on bowel movement and defecation following C-section.

A prospective study on the incidence of sore throat after use of laryngeal mask airway during general anesthesia.

Background: Laryngeal mask airway (LMA) is a useful alternative to intubation of the trachea to maintain the airways. The aim of this study was to evaluate the incidence of sore throat after LMA during general anesthesia in short-duration elective surgery.

Method: In this prospective study, 76 patients undergoing surgery with general anesthesia in (XXX) during 2018 and 2019 were selected and their demographic information were entered into the data collection form.

Surgical complications in colorectal cancer patients.

Background: Advancements in diagnostic and therapeutic sciences have allowed early diagnosis and treatment of cancer. Colorectal cancer is one of the most commonly reported cancers, particularly in elderly patients.

Methods: Open and laparoscopic surgeries are used for the removal of the tumor, along with chemotherapy, depending on the stage of cancer.

The Effect of Calcium Hydroxide and Nano-calcium Hydroxide on Microhardness and Superficial Chemical Structure of Root Canal Dentin: An Ex Vivo Study.

Introduction: Calcium hydroxide (CH) and nano-calcium hydroxide (NCH) as intracanal medicaments may affect the physical and chemical properties of dentin. The aim of this investigation was to evaluate the effects of CH and NCH on the microhardness and superficial chemical structure of radicular dentin.

Methods: In this in vitro trial, 80 dentin discs were randomly assigned into 2 control and 2 treatment groups (n = 20).

The Effect of Betamethasone Gel and Lidocaine Jelly Applied Over Tracheal Tube Cuff on Postoperative Sore Throat, Cough, and Hoarseness.

Purpose: The purpose of the study was to investigate the effect of betamethasone gel and lidocaine jelly (over tracheal tube cuff) compared with distilled water on the postextubation syndrome incidence (sore throat, cough, and hoarseness).

Design: Double-blind randomized clinical trial study was used.

Methods: Ninety-nine patients of either sex undergoing elective surgery, under general anesthesia with endotracheal intubation, were recruited.
