We report an 85-year-old woman with an L3 vertebral body fracture who presented with back pain, bilateral leg pain, and weakness after four months of conservative treatment. Because of unstable pseudoarthrosis, the L3 vertebral body collapsed in the standing position and the L3 nerve root was compressed. The indicated surgery decompressed the L3-L4 foramen and fused the unstable segment. The ba...

A 1-D and 2-D cylindrical flow stability is investigated in this paper. A typical velocity profile in a shear layer with infection point is studied first. The fluid motion is decomposed to two parts: the rotational part and shear part. Linear stability analysis shows the rotational part (like rigid body) is stable but the shear part is unstable. Of course, the shear layer with inflection point ...

A consensus statement from the International Cerebral Palsy Task Force outlined essential criteria to define an acute perinatal hypoxic event; criteria included evidence of a metabolic acidosis in fetal umbilical arterial cord blood or in very early neonatal blood samples (pH < 7 and base deficit >12 mmol/l). Pathological fetal acidaemia may be correlated with an increased risk of neurological ...

Daily counts of germinated seeds of white saxaul (Haloxylon persicum) incubated at 35 different hydrothermal environments (10-25?C and 0 to -3 MPa) were carried out under controlled laboratory conditions. The seeds were then buried in sand at 4 different depths in well drained pots constantly moisturized for three weeks. In all these hydrothermal conditions, the courses of germination were comp...

conclusions an extremely rare condition, a spontaneous intracranial pneumocephalus with skull base defect origin could be considered as a possible diagnosis in patients with sudden and severe headache. we can safely conclude that medical treatment and close follow-up is an effective mode of therapy in this patient. introduction spontaneous pneumocephalus without any pathological condition is ve...

BACKGROUND This case series report discusses patients presenting with hemorrhage and hemodymanic compromise due to severe pelvic fractures and undergoing intraoperative angioembolization (IAE) with other resuscitative procedures. METHODS We used portable digital subtraction fluoroscopy units for IAE in patients with severe pelvic hemorrhage and hemodynamic instability (5/03-4/09). Data was co...

The current survival sepsis guideline proposes the use of vasopressors and fluid resuscitation to maintain the mean arterial pressure (MAP) ≥ 65 mmHg. Titrating catecholamine infusion to achieve higher MAP has been demonstrated to improve tissue oxygenation, microcirculation, renal function and overall outcome of the patient in some studies and literature on actual hemodynamic goals is scarce. ...

There is no established method for accurately predicting how much blood loss has occurred during hemorrhage. In the present study, we examine whether a genetic algorithm neural network (GANN) can predict volume of hemorrhage in an experimental model in rats and we compare its accuracy to stepwise linear regression (SLR). Serial measurements of heart period; diastolic, systolic, and mean blood p...

introduction: drought is a natural and recurrent feature of climate. the characterizations of it may change under the effect of climate change in future periods. during the last few decades a number of different indices have been developed to quantify drought probabilities. droughts are caused by disruptions to an expected precipitation pattern and can be intensified by unusually high temperatu...
