Autonomic system disturbances in patients with increased intracranial pressure caused by brain tumors evaluated by heart rate variability.

Most of the disturbances of autonomic system (AS) activity seen in clinical practice result from head injury are due to development of increased intracranial pressure (ICP). It has been described that cerebral lesions produce hypersympathetic states mediated mostly by sympatho-adrenal discharge. Aim of the study was to evaluate effects of ICP on heart rate variability (HRV) in patients with brain tumors.

Myoelectric and autonomic nervous system activity in patients with irritable bowel syndrome.

Explanation of the main causes of symptoms and dysfunctions in the FGIDs is focused on visceral hypersensitivity. Sympathetic stimulation increases sensitivity of visceral receptors. Thus overall influences of the autonomic nervous system are important not only in regulation of secretion and motility of the gastrointestinal tract but also in visceral sensation.

[Gastric myoelectrical dysfunction in patients with hematoma of the posterior cranial fossa].

Demonstrated disturbances of gastric myoelectrical activity in 10 patients with hematoma of the posterior cranial fossa. Tachygastria amounts 40% of the recording time.

[Early disturbances of gastric myoelectrical activity in a patient with brainstem hematoma. Case report].

Described early disturbances of gastric myoelectrical activity in 18-years old patient, which appeared immediately after craniocerebral trauma. Brain MRI in a patient showed brainstem hematoma. Bradygastria amounts to 53.

[Cerebral hemorrhagic stroke and gastric myoelectric activity. Case report].

We showed case of subarachnoid hemorrhage with massive intracerebral hematoma of the left hemisphere and associating gastric myoelectrical disturbances. The cerebral angiography did not show vascular malformation. The electrogastrogram (EGG) at 2 days after the onset of neurological symptoms revealed tachygastria up to 66.

[Effects of intracranial hypertension on gastric myoelectrical activity evaluated by using clinical and radiological symptoms].

Background And Purpose: Acute and chronic increases in intracranial pressure (ICP) cause a dramatic autonomic dysfunction. The aim of the study is to evaluate effects of acute and chronic ICP on gastric myoelectrical activity.

Material And Methods: We studied 80 patients hospitalized in the Department of Neurotraumatology of the Jagiellonian University Medical College.

[Gastric myoelectric activity disturbance in patients with traumatic lesions of the brain stem].

The aim of the study was to evaluate effects of cranio-cerebral trauma on gastric myoelectric activity. Twenty four patients hospitalized in the Department of Neurotraumatology, Collegium Medicum of the Jagiellonian University were compared with a control group of 16 healthy volunteers matched for gender and age. Their gastric myoelectric activity was measured using standard cutaneous electrodes with Synectics, a Swedish system of data storage and analysis.

Gastric myoelectrical activity and intracranial hypertension.

Background: The aim of the study was to evaluate altered patterns of gastric myoelectrical activity in patients with high intracranial pressure due to severe craniocerebral injury producing intracranial hematomas, or to neoplastic processes in the central nervous system.

Material/methods: The study population consisted of 50 patients admitted to the Department of Neurotraumatology, Jagiellonian University College of Medicine. The controls were 16 healthy volunteers matched for gender and age.

Gastric myoelectric activity in patients with closed head brain injury.

Background: Traumatic brain injury (TBI) constitutes a major public health problem. Most of the acute disturbances of autonomic nervous system activity seen in clinical practice resulting from head injury are due to increased intracranial pressure (ICP), which precipitates a complex set of changes causing lack of food tolerance. The aim of our study was to evaluate the effects of TBI on gastric myoelectric activity in coma patients.
