Comparative Study[Pressure and flow-profile of different spinal needles].
The flow characteristics of four different types of spinal needles were investigated by measuring the infusion pressure during steady state infusion of either saline or an X-ray contrast agent. Two pencilpoint needles, a Whitacre 22Gauge and a Sprotte 24Gauge, possessed flow characteristics similar to a 22Gauge Quincke point needle. Use of pencilpoint needles for spinal anaesthesia results in a lower incidence of postdural puncture headache compared to the Quincke point needle. We therefore recommended the use of pencilpoint needles for myelography.

Case Reports[Nitrogen oxide inhalation in acute pulmonary failure].
Two cases of adult respiratory distress syndrome (ARDS) treated successfully with nitric oxide (NO) inhalation are described. One patient had severe sepsis and the other had trauma induced ARDS. The slow entry criteria for extracorporeal membrane oxygenation (ECMO) was fulfilled in both cases. ⋯ Treatment with NO inhalation was without side effects and easy to administer through the ventilator. Both patients survived without sequelae. We suggest that inhalation with NO should be tried before ECMO treatment is considered in severe ARDS.

[Long-term prognosis of pulmonary sarcoidosis. 1. Prognostic value of lung function and symptoms].
A follow-up of 254 patients with intrathoracic sarcoidosis has been carried out after a median of 27 years from diagnosis. All patients could be traced. No excess mortality was found (80 deaths observed versus 66 expected). ⋯ For overall mortality respiratory symptoms were also significant predictors; this was the case even after adjusting for age, sex, x-ray stage and lung function (FEV1 & TLC) at presentation. In conclusion, no excess mortality was observed after a median of 27 years follow-up. Lung function, respiratory symptoms and to some extent X-ray stage at time of diagnosis influenced long-term mortality in patients with intrathoracic sarcoidosis.
