Potential application of foveal structural measurements in treatment decision for retinopathy of prematurity: an OCT-based study.

Purpose: To investigate foveal changes in infants with ROP not requiring treatment(nROP) and ROP infants needing treatment (tROP) using a handheld SD-OCT device.

Method: We performed horizontal SD-OCT scans through the fovea in 156 eyes of 81 infants diagnosed with ROP. Foveal immaturity indices including the presence of inner retinal layers (IRL), absence of foveal outer nuclear layers widening (ONL) and attenuation of hyperreflective outer segment layers (OS), presence and type of cystoid macular edema (CME), epiretinal membrane (ERM), foveal pit depth (FPD), foveal pit width (FPW) and central foveal thickness (CFT) were calculated.

Comparison of the Laryngoscopic View using Macintosh and Miller Blades in Children Less than Four Years Old.

This study aimed to compare Miller and Macintosh laryngoscopes in zero to 4-year-old children. A total of 72 children with a score of I and II, according to the American Society of Anesthesiologists (ASA) physical status classification, who were candidates for elective surgery with general anesthesia and tracheal intubation were enrolled in the study. The children were divided into two equal groups (36 persons) according to used laryngoscope: Miller laryngoscope (group 1) and Macintosh laryngoscope (group 2).

Novel evaluation of sevoflurane anesthetic exposure on the testicular germ cells of neonatal male mice.

: Inhalatory anesthetics may impact spermatogenesis and sexual behavior. Comprehensive evaluation should be conducted to screen the effect of inhalatory anesthetics on the sperm and semen quality. This experimental research was organized to assess the impacts of sevoflurane during the period of neonatal spermatogenesis.

[Effects of repeated exposure to different concentrations of sevoflurane on the neonatal mouse hippocampus].

Background And Objectives: Developing brain is more vulnerable to environmental risk than is the developed brain. We evaluated the effects of repeated exposure to different concentrations of sevoflurane on the neonatal mouse hippocampus using stereological methods.

Methods: Eighteen neonatal male mice were randomly divided into three groups.

Exposure of neonatal mice to Sevoflurane may induce male germ cell apoptosis in testicular tissue after puberty.

Background: common use of sevoflurane in congenital defects during repeated surgeries may have detrimental effects on spermatogenesis after puberty.

Objective: This study investigated sevoflurane effects on spermatogenesis process in male mature mice after exposure in prepubertal time.

Materials And Methods: 24 neonatal NMRI male mice were randomly classified in three groups.

Ondansetron pretreatment reduces pain on injection of propofol.

Unlabelled: To assess the effectiveness of ondansetron pretreatment in alleviating propofol injection pain, 135 patients were randomly assigned to one of following three groups. Group 1 who received up to 2 mL pretreatment 50 mg tramadol in the saline, group 2 cases who received up to 2 mL pretreatment 4 mg ondansetron in saline, and group 3 who received up to 2 mL solution saline. A 20 gauge cannula was placed into the largest vein on the dorsum of the hand.

A comparison of the upper lip bite test with hyomental/thyrosternal distances and mandible length in predicting difficulty in intubation: A prospective study.

The incidence of difficulty in tracheal intubation has been reported to range from 0.5 to 18% in patients undergoing surgery. We aimed to elucidate the role of upper lip bite test (ULBT) with other prevailing tests, hyomental/thyrosternal distances (HMD/TSD), and the mandible length (ML) and their possible correlation in predicting difficulty in intubation.
