[Hydrocephalus as a sequel of hemorrhage from ruptured cerebral aneurysm in light of CT investigations].

In the years 1985-1987 CT studies were carried out in 182 patients after haemorrhage from ruptured intracranial aneurysm. The study was carried out before surgery or the patients were not operated on for various reasons. Hydrocephalus was found in 33 cases, that is 18.2%. The patients were divided into subgroups depending on the time of CT after haemorrhage and on the state according the Hunt-Hess classification. Since only a small per cent of cases fell into the I and II categories of the classification, one may state that posthaemorrhagic hydrocephalus is connected usually with worse condition of the patient. Early hydrocephalus was relatively rare. In only a part of the cases CT was done on the first day after haemorrhage and it was difficult to say whether the presence and amount of blood in the basal cisterns and over the convexity contributed significantly to the development of hydrocephalus. However, in half the cases with intraventricular bleeding hydrocephalus was present.

[Subarachnoid hemorrhage of unknown etiology].

A group of 73 patients is described in whom diagnostic procedures failed to demonstrate the source of haemorrhage. In this group 92% of patients were in good clinical condition after the episode (I and II clinical group). In only one patient with angiographically demonstrated diffuse vasospasm in one cerebral hemisphere signs of focal brain damage developed leading to death. The remaining 95.9% of patients left the hospital in good condition, without focal signs. During follow-up in two (3.2%) out of 62 patients with known condition a recurrence of subarachnoid haemorrhage developed. Most patients were in good condition, fully fit up to 3 years after the haemorrhage. In summary, the authors stress a mild course of subarachnoid haemorrhage of unknown aetiology, good prognosis as to return of full fitness, and relatively low risk of development of focal brain damage or death from haemorrhage.

Relationship between G band number and chromosome length from prophase to metaphase.

The statistical analysis of the distribution of human chromosomes length served as a basis for their classification according to the suggestions of the Denver Conference (1960). Standards of metaphasal chromosome length were used for programmes of computer-assisted classification. The introduction of banded chromosomes in the study provided a new measurable feature which was used for classification standards accepted at the Paris Conference (1971). The measurements of these two features have been used also in the mathematical models of computer analysis and classification of chromosomes. In the present study the relationship between the number of bands and the length of chromosomes was studied in the period of cell division from prophase to metaphase in the cultures of leucocytes of healthy people. This relationship is strongly correlated and can be approximated in description to simple regression in the period from prophase to metaphase. The relationship will facilitate the construction of dynamic patterns for the needs of computer-assisted classification of chromosomes and detection of structural aberrations.

[Antigravity suit used for neurosurgical operations in sitting position].

The aviator's antigravity suit (G-suit) was used for 40 operations on neurosurgical patients operated on in sitting position. The G-suit was filled with air to 0.2 atmosphere (20 kPa) pressure in 26 cases, and 0.3 atm. (30 kPa) in 14 cases. In all cases G-suit filling was followed by central venous pressure rise and mean arterial pressure rise. Venous air embolism was found in 5 (12.5%) patients. No other complications connected with the use of G-suit were observed.

[Non-traumatic nasal cerebrospinal rhinorrhea].

Non-traumatic rhinorrhoea of CSF occurs much less frequently than traumatic ones. The most frequent causes of this rhinorrhoea are congenital abnormalities of the cranial bass. Non-traumatic rhinorrhoea with normal cerebrospinal fluid pressure and those with raised CSF pressure are known. In the latter rhinorrhoea is one of the signs of a disease causing CSF pressure rise. In view of the rare occurrence of nontraumatic rhinorrhoea 6 cases are reported which were treated in the years 1986-1993 in the Neurosurgery Department, Medical Academy in Warsaw.
