[Hyperventilation in military aviation and diving]

The most important risk of aviation [in altitude over 10 thousand feet] and sub aquatic seafaring [in depth exceed over 30 meters] is hyperventilation. The problems manifested itself at first and especially second world war when pilots flew at altitude over 10 thousand feet. Those pilots had some signs and symptoms while faced mental and physical stresses that eventuated in aircraft crash. This study collected related data from several books, articles and knowledge about military and civil aviation. Etiology of hyperventilation is related to stressing [mental and physical problems] such as ambient changes [temperature, pressure and, etc], face to emergency situations, physiological and mental changes and, etc. Signs and symptoms were different in everyone this manifestations cause from motor and sensory impairment, psychomotor, cognitive, neuromuscular, consciousness and death. These risks are more important in military aviation due to highest performance and in seafaring because stresses in the work. The astronauts, air crews, sea crews and athletics always have consciousness and higher performance. Thus informing them about hyperventilation and its complications, prevention and treatment for population are necessary

[Role of Staphylococcus coagulase negative in neonatal sepsis in patients admitted at Ghods hospital [Ghazvin-autumn 2006]]

According to the high prevalence of neonatal infection and reduce of NMR [neonatal mortality rate] as one of the health and treatment program in our country, study about prevalence of blood infection germs and predisposing factors seem necessary. In this cohort study, 118 neonat that admitted in neonatal ward and NICU of ghods hospital along 3 month evaluated based on many items such as: BC [blood culture] /sex/age/admission date/ weight/type of birth/admission ward/clinical findings/predisposing factors. All of this informations acquired from patients profil. Evaluation results of 118 neonat that admitted along 3 month at ghods hospital neonatal ward and NICU that shown 26 patient [%22] have positive BC and 92 patients [%78] have negative BC. Based on result of this study found that:%22 neonat have positive BC and%78 have negative BC. responsible of%34.6 positive BC was Staphylococcus cougulas negative and%65.4 was other germs. Most common predisposing factor was pretermity [%10.2] and most common clinical finding was fever [%66.9]
