Case ReportsPostpartum headache, seizures and bloodstained C.S.F.: a possible complication of dural puncture?
A 32-year-old parturient developed severe headache with subsequent convulsions on the third day after the delivery under epidural anesthesia. Neuroradiological investigations were negative. All complaints disappeared promptly after the performance of an epidural blood patch.

Audit of intensive care: a 30 month experience using the Apache II severity of disease classification system.
608 patients admitted to a general Intensive Care Unit (ICU) over a 30 month period were analyzed according to the Apache II Severity of Disease Classification System on day one of admission. Hospital outcome details were available on 583 patients in the series. ⋯ Our higher than predicted mortality (mortality ratio 1.2) in comparison with centres in the United States of America (US) may be partly explained by the high proportion of our population from these unfavourable groups, by our use of the best Glasgow Coma Scale in the first 24 h following admission, and the major differences between our patient population and that of the US upon which the Apache II was based. The presence of these large unfavourable groups indicates a change in our admission policy is warranted.

Case ReportsMiliary tuberculosis presenting as adult respiratory distress syndrome.
We report the history of a 27-year-old Caucasian girl who died of adult respiratory distress syndrome secondary to miliary tuberculosis (MTB), after treatment with antibiotics to which the organism was sensitive, and a long period of ventilation. This case emphasises the importance of considering MTB as the cause of respiratory failure when another aetiology is not apparent.

Comparative StudyTotal inspiratory work with modern demand valve devices compared to continuous flow CPAP.
The inspiratory work exerted by an electromechanical lung model in drawing a 500 ml breath, was assessed by planimetry of pressure/volume loops for six commercial demand valve CPAP devices (Servo B and C from Siemens, EV-A and UV-2 from Dräger, the Puritan Bennett 7200 and the Engström ERICA) and compared to the loading of a conventional high flow CPAP system. The effect of trigger sensitivity and inspiratory pressure support on inspiratory work was also investigated in some cases. The lung model allowed for calibrated changes in compliance and airway resistance. ⋯ Halving compliance doubled the work and exchanging a 7 for a 9 mm i.d. endotracheal tube in the circuit increased work by about 3% regardless of machine. Decreasing trigger sensitivity from 0 to 2 cm H2O for the Servo B increased work by up to 24%. Using 5 cm H2O of inspiratory pressure support decreased work for all machines up to 36% maximally.(ABSTRACT TRUNCATED AT 250 WORDS)
