The Long-Term Sequelae of Traumatic Brain Injury Over 10 Years of Follow-Up—A Matched Cohort Study Based on Routine Data of a Statutory Health Insurance Carrier.

Background: The acute effects of traumatic brain injury (TBI) are well documented, but there is no systematic quantification of its long-term sequelae in Germanlanguage literature. The purpose of this article is to compare the frequency of conditions linked to prior TBI with their frequency in the non-brain-injured population.

Methods: A matched cohort study was carried out on the basis of routine data from the BARMER statutory health insurance carrier.

Health-related quality of life after spontaneous subarachnoid hemorrhage measured in a recent patient population.

Objective: This study sought to determine the impact of spontaneous subarachnoid hemorrhage (SAH) on health-related quality of life (HRQOL).

Methods: Data were taken retrospectively from 601 patients (219 male, 382 female) treated between 1998 and 2008. Questionnaires concerning HRQOL were circulated prospectively, and the responses from 253 patients (81 male, 172 female) were analyzed.

Stationarity in neuromonitoring data.

Purpose: Signals reflecting the metabolic and circulatory status of an injured central nervous system are normally corrupted systematically. The patient is part of a therapeutic control-loop and the signals acquired are rather determined by the quality of control (stationarity of signals) than by the underlying pathological process.

Methods: To verify the control-loop hypothesis, neuromonitoring data from 12 randomly selected severely head injured patients (initial GCS ≤ 8, 7 men, 5 women) were analysed for circulatory (blood pressure, intracranial pressure [ICP], cerebral perfusion pressure [CPP]) and metabolic (arterial blood gases, jugular bulb oxygenation [SjvO(2)], brain tissue oxygen partial pressure [ptiO(2)]) variables (n = 10).

Analysis of intracranial pressure time series using wavelets (Haar basis functions).

Purpose: Transforming intracranial pressure (ICP) into frequency domain commenced in the early 1980s, arriving at the conclusion that cerebrospinal dynamics were mapped by ICP spectral composition. Classical analysis tools were not suitable for handling intrinsic signal non-stationarity. To overcome inherent obstacles we introduce a novel approach based upon wavelets.

Head injury in Germany: A population-based prospective study on epidemiology, causes, treatment and outcome of all degrees of head-injury severity in two distinct areas.

Introduction: Little is known about the ratio of mild traumatic brain injury (TBI) to moderate and severe TBI, about the time that elapses until primary care is given, about the number of patients requiring immediate surgery and about the early outcome and the costs.

Method: In a prospective study two regions taken as model examples were investigated: the City of Hanover with its surrounding catchment area and Münster with its regions.

Results: From 1 March 2000 until 28 February 2001 all patients were recruited who were admitted to a hospital emergency department due to a TBI; 6783 patients (58.

Head trauma in children, part 3: clinical and psychosocial outcome after head trauma in children.

With the aim of determining long-term outcome, the authors approached 38 families (average 2.1 years after trauma) with a questionnaire, following the acute-clinical treatment of head trauma of their children. Long-term damage was restricted almost exclusively to patients presenting with a Glasgow Coma Score < or =8.

Head trauma in children, part 1: admission, diagnostics, and findings.

The objective of this study is to describe and to determine the preclinical situation and early in-clinical situation, diagnostic findings, and factors influencing the outcome of severe head trauma in children. Records of 48 children (0-16 years) were analyzed during a 3-year interval. Correlations with the outcome (Glasgow Outcome Scale) were determined by focusing on different scales, clinical findings, biochemistry, and clinical course features.

Head trauma in children, part 2: course and discharge with outcome.

To minimize the secondary brain damage, we analyzed the effect of cerebral perfusion pressure-orientated management and tried to find factors of clinical management and biochemical findings that influence clinical, cognitive, and psychosocial outcome. Management at intensive care unit was standardized. A standardized (short form 36 health survey) and nonstandardized split questionnaire explored long-term outcome.

The use of recombinant activated factor VII in neurosurgery.

Background: Bleeding complications in neurosurgery often take alarming proportions without major hemodynamic effect or impairment of coagulation physiology because severe neurologic deficits are to be expected. Any measures used to stabilize or normalize coagulation are therefore of great interest. Administration of packed red cells, fresh frozen plasma, and platelet concentrates is associated with volume loading, which is suspected to multiply the secondary brain damage, for example, by the development of an edema.

Fracture of the occipital condyle caused by minor trauma in child.

We report a case of fractured occipital condyle caused by minor trauma accompanied by light pain on palpation at the lateral cervical trigonum. A 15-year-old boy complained of nuchal pain, particularly pain on palpation at the left lateral cervical trigonum in the absence of neurologic deficits after head deceleration trauma. Computed tomography demonstrated a unilateral nonluxated fracture of the occipital condyle.
