Epidemiological Characteristics of Shiga Toxin-Producing Responsible for Infections in the Polish Pediatric Population.

Shiga toxin-producing (STEC) are zoonotic pathogens causing hemorrhagic colitis and hemolytic uremic syndrome (HUS) in children and the elderly. Stool samples were collected from 180 children hospitalized in five pediatric centers in Poland in 2018-2022. Direct / gene detection by PCR in feces and isolates was performed.

[Leukapheresis in children with chronic myeloid leukemia and pulmonary leukostasis].

We present two patients with chronic myeloid leukemia and hyperleukocytosis above 350 x 10(9)/l causing the symptoms of pulmonary leukostasis. Therapeutic leukapheresis procedures with concomitant chemotherapy were initiated within 12 hours from the diagnosis. After the therapy commencement the general condition of the patients systematically improved and leukocytosis gradually decreased from the second day of treatment with disappearance of pulmonary leukostasis symptoms.

[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.

Medical and surgical treatment of intracerebellar haematomas.

15 cases of intracerebellar haematomas [11 spontaneous, 2 traumatic and 2 unclear] were presented. Hypertension was thought to be a main risk factor in 91% in 11 of the spontaneous cases. 11 cases were treated medically.

[Erdheim's tumors in adults--diagnosis, treatment and therapeutic results].

The authors present a group of 27 adult patients aged over 25 years treated in the Department of Neurosurgery, Medical Academy in Warsaw in the years 1960-1985 for Erdheim's tumours. In most cases the first signs were visual disturbances and signs of raised intracranial pressure, and in only 48% of cases endocrine disturbances were additionally found. The basic diagnostic method in these cases was computerized tomography which indicates precisely the location of the lesion, its consistency and width of ventricles.

[Conservative treatment of intracranial hematomas and the dynamics of their resorption].

In 10 out of 63 patients with intracerebral haematomas treated conservatively the authors measured approximately the volume of haematomas by means of serial CT examinations during observation of their resorption. These were large and medium-size haematomas, from 20 to 70 ml in volume. The mean rate of resorption was from 0.

[Clinical, electroencephalographic and cerebral computerized-tomographic findings in patients with ischemic stroke].

The clinical findings, EEG and CT examinations of the brain were compared at three time intervals in patients with ischaemic stroke. No evident correlation was found between the intensity of clinical signs, the intensity of EEG changes and the size of the ischaemic focus in the CT. It was observed that with increasing time interval after the onset of the disease the clinical state and EEG changes improved while the CT image was not changed or even became worse.

Cytostatics for acromegaly. Marked improvement in a patient with an invasive pituitary tumour.

A 21-year-old woman suffering from acromegaly was treated with transsphenoidal subtotal hypophysectomy (microscopy: acidophilic adenoma), followed by x-ray and bromocriptine therapy. Seven years later she was re-operated because of a partial bitemporal loss of vision, intracranial hypertension, and regrowth of the pituitary tumour seen on CT-scan. A large part of the invasive suprasellar tumour was then removed by transcranial approach.

[Conservative treatment of selected cases of chronic paracerebral hematoma].

The authors report an analysis of the course of 16 cases treated conservatively for paracerebral haematomas. The diagnosis was based on angiographic findings of computerized tomography (CT). Haematoma resorption was confirmed by CT.

[A case of conservatively treated multiple brain abscesses].

A patient is reported with multiple brain abscesses in whom conservative treatment gave a good result. Attention is called to the small number of such cases described as yet. In accordance with the observations of other authors it is stressed that this treatment is possible only if repeated CT control examinations are available, and only if no raised intracranial pressure is present.

Encephalomalacia in the distribution of the posterior cerebral and superior cerebellar arteries: the CT and radionuclide examination.

The case described concerns the clinical diagnosis of a vascular focus in the distribution of the posterior cerebral and superior cerebellar arteries. Up to now both carotid and vertebral angiography were required. Nontraumatic CT and radionuclide studies have allowed demonstration of the etiology of the disease in the occipital and cerebellar region without further neuroradiology examinations with contrast.

[Value of axial computerized tomography for the evaluation of the effectiveness of the ventriculo-atrial shunt].

The authors describe 32 cases of hydrocephalus of different aetiology in which the effectiveness of the ventriculoatrial shunt was evaluated by means of repeated computerized axial tomographic (CT) investigations. This investigation made it possible to demonstrate in a way not exposing the patients to any complications that the shunt was effective in 87.4% of cases with reduction of the size of the ventricular system of significant and moderate degree.

[Neuroradiological studies in syringomyelia].

In the years 1973--1975 20 patients with syringomyelia were treated surgically. The surgical interventions were preceded by careful radiological examinations which was often indispensable for confirmation of diagnosis, establishing of indications to operation and choice of surgical method. On plain radiograms in 16 cases cervicothoracic scoliosis was found, in 11 cases the vertebral canal was dilated in its cervical part, in 6 cases atlanto-occipital malformations were disclosed.
