[Elevation of the diaphragma after cardiac surgery].

Phrenic nerve injury and diaphragmatic dysfunction can be induced by cardiac operation. We evaluated nonconsecutive 34 patients (pts) with elevation of the diaphragma after cardiac operation. 27 pts have coronary artery bypass grafting, 7 pts have prosthetic valve implantation. We have impression that ice/saline slush used along with cold cardioplegia for heart arrest can cause hypothermic damage of phrenic nerve. Palsy of that nerve results in raised hemidiaphragm and delayed recovery of the pts. In our pts normalisation of the diaphragm we observed 6 months after operation in 41% pts and 12 month after in 93% pts. We suggest that results depends on early and well rehabilitation.

[Results of the treatment of idiopathic hydrocephalus by shunt implantation after computerized cisternography].

A retrospective study was reported of 19 patients (10 males and 9 females aged from 11 to 65 years) with idiopathic hydrocephalus treated by shunt implantation after qualification for this treatment based on computed tomocisternography. Clinical improvement was noted in 16 patients (84%), and after 2 months the therapeutic results by Black's scale were good in 13 patients (65%).

The respiratory response to magnetic stimulation of the cortex in the unanaesthetized baboon.

Transcranial magnetic stimulation has been used to study cortical input to the respiratory system in unanaesthetized baboons. Single magnetic pulse caused usually a short-latency excitation with subsequent inhibition in stimulated inspiratory phase and change in the amplitude and timing of the respiratory cycle. The results suggest that cortical information is processed by the medullary pattern generator.

Grave cranio-cerebral trauma 30 years ago as cause of the brain glioma at the locus of the trauma particulars of the case.

A glioblastoma multiforma developed 30 years after a penetrating craniocerebral injury in the left parietal region caused by fragments of an artillery projectile. The 3 cm large bone defect was located directly above the tumour. There were close scarry connections between dura, brain and tumour. Partial removal could not prevent the lethal exitus. Causal connection with the accident is assumed to exist.

Studies on reflex control of breathing in pigs and baboons.

In 8 pigs and 4 baboons, spontaneously breathing, anaesthetized with halothane, Hering-Breuer reflex was tested by means of a total obstruction of the airway preventing either inspiration or expiration. Subsequently animals were paralysed and maintained on phrenic nerve driven servo-respirator. The response of phrenic motoneurone output to various degree of lung inflation, introduced for one breath only, was then carefully studied. This was achieved by varying the gain of servorespirator. Additionally in baboons, identical series of gain manoeuvres was performed against a background of different levels of the initial gain setting. Changes in both inspiratory time and peak amplitude of phrenic signal were monoexponentially dependent on gain of servorespirator and linearly dependent on tidal volume (all negatively correlated). The relationship between inspiratory time T(1) and subsequent expiratory duration T(E )existed only within a range of growing T(1). Vagal positive feedback phenomenon was apparent in pigs and negligible in baboons. It is postulated that inspiratory cut-off mechanism terminates inspiration when excitatory function are outbalanced by their integral.

[Spontaneous acute subdural hematoma].

A rare case of spontaneous acute subdural haematoma is reported. Causes of non-traumatic subdural haematomas are discussed stressing the necessity of rapid surgical intervention.
