Medial canthus single injection a comparative study between articaine and prilocaine

To compare the efficacy of 4% articaine with 4% prilocaine for peribulbar anesthesia in ocular surgery using single medial canthus injection technique. One hundred patients scheduled for elective ocular surgery were randomly selected to receive 8ml of articaine 4% with 1:200,000 adrenaline [ultracaine D-S], or to receive 8ml of prilocaine 4% with 1:200,000 adrenaline [citanest fort]. Hyaluronidase 20IU/ml was added to both solutions. The end results were evaluated. Articaine had a more rapid onset of action as regards extra-ocular muscle paralysis, similar potency and less incidence of restoring to supplementary anesthesia. In comparison to prilocaine in single medial canthus peribulbar anesthesia. 4% articane is a good competitor to 4% prilocaine in peribulbar anesthesia

Bone mass of healthy newborns in relation to their maternal and cord blood long-chain polyunsaturated fatty acids

The objective of this study was to establish that long chain polyunsaturated fatty acids [LC PUFA] status is associated with or related to bone mass in healthy infants. Twenty- eight mother-infant pairs were studied for LC PUFA status by measuring maternal and cord blood red blood cells [RBC] for arachidonic acid [AA], eicosapentenoic acid [EPA] and docosahexenoic acid [DHA]. Infant anthropometry and lumbar spine 1-4 femur and whole body bone mineral content [BMC] were measured within two weeks of delivery. Maternal and infant LC PUFA were tested for their relationship to BMC using Pearson correlation and regression analysis. At birth, the average gestational age was 38.5 +/- 1.5 wk and body weight was 3.29 +/- 0.723 kg. Cord blood AA was positively correlated with whole body BMC, AA:EPA positively correlated with lumber spine 1-4 BMC and femur BMC. Maternal RBC AA was positively correlated with whole body BMC. After accounting for infant weight using regression, whole-body BMC was positively predicted by cord RBC AA but none of the maternal LC PUFA. Lumber spine 1-4 BMC was positively predicted by cord RBC AA: EPA ratio. Both femur and lumber spine 1-4 BMC were negatively predicted by maternal DHA. Imbalances among the n-6 and n-3 LC PUFA by term gestation may be related to decreased bone mass, suggesting that the maternal diet should be balanced in in-6 and n-3 LC PUFA
