BACKGROUND One of the measures of the pulmonary function is the peak expiratory flow (PEF) that can be defined as the major flow obtained in an expiratory pressure after a complete inspiration to the level of the total lung capacity. This measure depends on the effort and strength of expiratory muscles, the airway diameter and the lung volume. OBJECTIVE To compare the results of the peak expi...

BACKGROUND Atelectasis is a common finding in mechanically ventilated children with healthy lungs. This lung collapse cannot be overcome using standard levels of positive end-expiratory pressure (PEEP) and thus for only individualized lung recruitment maneuvers lead to satisfactory therapeutic results. In this short communication, we demonstrate by lung ultrasound images (LUS) the effect of a p...

This article reports a clinical case of a 13-year-old girl, who was referred with chief complaint of a non-esthetic maxillary central incisors position. Five years ago, her maxillary right and left central incisors and left lateral incisor intruded into the maxilla. The intruded teeth were splinted for a month. After splint removal, the patient lost follow up. The aim of this work is to report ...

A 20-year-old woman was admitted to a Gynecology Hospital in her 6th month of pregnancy for high blood pressure and tonic-clonic seizure. Primary diagnosis was eclampsia, and for that reason she underwent cesarean section. She also had headache on frontal and parietal areas without nausea or vomiting. There was not a focal neurological sign. Rheumatology consultation was requested. Systemic lup...

introduction: analysis of smile is one of the esthetic evaluations in dentistry. in the present study, gla, lid, the long axis position and the oblique axial angle of each tooth were evaluated. materials and methods: in this cross-sectional analytical study, 80 subjects with properly-aligned teeth and healthy periodontium were selected. a digital camera was to take photos of lip areas in unifor...

BACKGROUND Recent data suggest that during mechanical ventilation the lateral-horizontal patient position (in which the endotracheal tube is horizontal) decreases the risk of ventilator-associated pneumonia, compared to the recommended semi-recumbent position (in which the endotracheal tube slopes downward into the trachea). We tested the feasibility of the lateral-horizontal patient position, ...

A 45-year-old man attended neurosurgery department for right lower limb burning pain of three months duration. The pain was intermittent, exacerbated by sitting position, and radiated from the proximal posterior part of the right lower limb to the lateral area of the leg, and the dorsal aspect of the foot. The pain was not severe enough to disturb sleep, or to hinder physical activities. The de...

Identical location of accessory pathways in family members with Wolff-Parkinson-White syndrome, although theoretically possible, has never been described. A 37-year-old woman and her 18-year-old son were referred for electrophysiological study due to fast rate palpitations and pre-excitation on baseline electrocardiogram. After mapping during pre-excitation, successful radiofrequency applicatio...

Classifications of (α,β )-fuzzy left (right and lateral) ideals of ternary semigroups are discussed. Relations between (∈,∈ ∨q)-fuzzy left (right and lateral) ideals and (q,∈∨q)-fuzzy left (right and lateral) ideals are established. Given special sets, so called t-q-set and t-∈∨q-set, conditions for the t-q-set and t-∈∨q-set to be left (right and lateral) ideals are considered. Conditions for a...
