Bronchiolitis obliterans (BO) is the main pulmonary involvement resulting from sulfur mustard (SM) gas exposure that was used against Iranian civilians and military forces during the Iran-Iraq war. The present study aimed to investigate the prevalence of gastro-esophageal reflux (GER) and gastric micro-aspiration in SM gas injured patients with chronic pulmonary diseases and recurrent episodes of exacerbations. ⋯ Most of BO patients after exposure to SM suffer GER, while none the etiologic factors of GER in post lung transplant BO are present. It would be hypothesized that GER per se could be considered as an aggregative factor for exacerbations in patients. Further studies will provide more advances to better understanding of pathophysiological mechanism regarding GER and BO and treatment.

Postoperative nausea and vomiting are some of the important and common side effects of anesthesia after surgery occurring in almost 20-30% of patients and is the second factor of a patient's complaint and inconvenience after pain. This study compares the effect of oral cetirizine and ondansetron in the prevention of postoperative nausea and vomiting in adults. ⋯ The PONV rate in cetirizine and ondansetron groups was less than the placebo group.

Clonidine, an alpha-2 adrenergic agonist, increases the quality of perioperative sedation and analgesia with a few side effects. This study was designed to assess the effect of clonidine premedication on the anesthesics used for elective below knee surgeries in opium abusers and non-abusers. ⋯ Adding clonidine as a preoperative medication decreases the patient's anesthetic needs; this decrease was even more considerable on the anesthetic needs than the effect of opium abuse history on anesthetic dose.

Although nursing education in Iran has a positive trend in growth; it is still facing with multifaceted challenges. This study aims to explore the challenges for effective evaluation of nursing education perceived by academic managers. ⋯ The results emphasize the need for educational evaluation development in nursing, including systematic and regular educational evaluation planning focusing on efficient feedback system and regard to excellence models. The comprehensive educational evaluation requires participation, involvement, and collaboration among the Nursing Board, Nursing ministerial office, faculties of nursing, and Nursing Organization. Thus, it is necessary to better designate current educational evaluation systems, policies, approaches, methods, and procedures.

Obstructive sleep apnea (OSA) syndrome is predisposed to the development of upper airway obstruction during sleep, and it poses considerable problem for anesthetic management. Difficult intubation (DI) is an important problem for management of anesthesia. In this clinical research, we aim to investigate the relationship between DI and prediction criteria of DI in cases with OSA. ⋯ OSA patient's DI ratio is higher than that of non-OSA patients. BMI Mallampati grading, Wilson weight scores, Laryngoscopic grading, sternomental distance, and tyromental distance evaluation might be predictors for DI in patients with OSA.
