German Physicians and Medical Students Do Not Represent the Population They Serve.

Medical professionals who represent the communities they serve are in a better position to understand patients' social circumstances and communicate in a more patient-centered way. International studies show limited diversity and underrepresentation of certain social groups in the population of physicians and medical students. We designed an observational study to investigate the cultural and socio-economic diversity of physicians and medical applicants in comparison to the general population in Germany.

Operative versus non-operative treatment of traumatic brain injuries in patients 80 years of age or older.

Traumatic brain injury (TBI) in older adults is an increasing issue in modern medicine. Nevertheless, it remains unclear which patients presenting with TBI and 80 years of age or older benefit from an operative treatment. The aim of this study was to explore the effect of an operative treatment in isolated TBI patients ≥ 80 years of age.

Predictive factors associated with ventriculoperitoneal shunting after posterior fossa tumor surgery in children.

Purpose: The aim of the study was to evaluate established risk factors and define new inflammation-associated factors associated with postoperative ventriculoperitoneal shunt placement.

Methods: The electronic medical records of children who underwent surgery for a tumor in the posterior fossa between January 2009 and January 2018 were retrospectively analyzed. Factors evaluated include age, clinical symptoms, tumor type, extent of surgical tumor resection, treatment with EVD and/or ETV, radiological findings, postoperative serum CRP, and leucocyte levels.

Cost Comparison of Surgical Clipping and Endovascular Coiling of Unruptured Intracranial Aneurysms: A Systematic Review.

Objectives: Rupture of unruptured intracranial aneurysms (UIA) is the main cause for subarachnoid hemorrhage. UIA are widespread among the population. Advanced technology enables us to diagnose UIAs with increasing reliability and subsequently treat them.

Observed versus expected mortality in pediatric patients intubated in the field with Glasgow Coma Scale scores < 9.

Purpose: A Glasgow Coma Scale (GCS) score of 8 or less in patients suffering from severe traumatic brain injury (TBI) represents a decision-making marker in terms of intubation. This study evaluated the impact of prehospital intubation on the mortality of these TBI cases among different age groups.

Methods: This study included the data from patients predominantly suffering from severe TBI [Abbreviated Injury Scale (AIS) of the head ≥ 3, GCS score < 9, Injury Severity Score (ISS) > 9] who were registered in TraumaRegister DGU from 2002 to 2013.

Repair of Occipital Bone Defects in Neurofibromatosis Type 1 by Means of CAD/CAM Prefabricated Titanium Plates.

Certain skeletal defects may develop in neurofibromatosis type 1 (NF1), a common tumor-suppressor syndrome, such as cranial lesions confined to the lambdoid suture region. Here, we report on the repair of osseous defects of occipital bone in a NF1 patient with history of skull trauma and tumorous hemorrhage. Computer-aided design and computer-aided manufacturing (CAD/CAM)-assisted devices were applied to safely close the bone defects.

Tectal gliomas: assessment of malignant progression, clinical management, and quality of life in a supposedly benign neoplasm.

OBJECTIVE Tectal gliomas constitute a rare and inhomogeneous group of lesions with an uncertain clinical course. Because these supposedly benign tumors are frequently followed up by observation over many years, the authors undertook this analysis of their own case series in an effort to demonstrate that the clinical course is highly variable and that there is a potential for a progressive biology. METHODS Clinical data analysis of 23 cases of tectal glioma (involving 9 children and 14 adults) was performed retrospectively.

Sport-Related Traumatic Brain Injury with and without Helmets in Children.

Background: Soccer, bicycling, and horseback riding are sports most commonly associated with traumatic brain injury (TBI) in Germany. The latter 2 sports activities are commonly practiced with helmets, and data on helmet use and usefulness vary widely.

Methods: On Ethics Committee approval, a retrospective analysis was performed for patients age 5-17 between January 2009 and August 2014 based on a diagnosis of TBI, using the electronic patient file for 2 university hospital locations.

Body Mass Index >35 as Independent Predictor of Mortality in Severe Traumatic Brain Injury.

Objective: Severe traumatic brain injury (TBI) has a major influence on polytrauma outcome. The aim of this study was to evaluate the impact of body mass index (BMI) on mortality and early neurologic outcome in patients suffering from severe TBI with a special focus on obesity classes II and III (BMI ≥35).

Methods: A retrospective cohort analysis of patients suffering from a leading, at least severe TBI and registered in the TraumaRegister DGU was conducted.

Secretory Meningiomas: Increased Prevalence of Seizures Secondary to Edema Formation in a Rare Histologic Subtype.

Objective: Secretory meningioma (SM) is a rare histologic subtype known to cause disproportional peritumoral brain edema. Although meningiomas are defined by slow growth and mostly manifest with benign clinical symptoms, SMs can cause life-threatening deterioration. The aim of this study was to characterize the potential pitfalls in treatment of SMs by illustrating their characteristic clinical features.

Meninigiomas of the Craniocervical Junction--A Distinctive Subgroup of Meningiomas.

Objective: Meningioma of the cranio-cervical junction is a rare diagnosis and demand a thorough surgical planning as radical excision of these tumors is difficult. In this context recurrence is most likely due to regrowth of residual tumor. The aim of this study was to evaluate the clinical course of patients operated for craniocervical meningioma (CCM) and to investigate the histological features of these tumors and their impact on recurrence rate.

Impact of Glasgow Coma Scale score and pupil parameters on mortality rate and outcome in pediatric and adult severe traumatic brain injury: a retrospective, multicenter cohort study.

OBJECTIVE Prediction of death and functional outcome is essential for determining treatment strategies and allocation of resources for patients with severe traumatic brain injury (TBI). The aim of this study was to evaluate, by using pupillary status and Glasgow Coma Scale (GCS) score, if patients with severe TBI who are ≤ 15 years old have a lower mortality rate and better outcome than adults with severe TBI. METHODS A retrospective cohort analysis of patients suffering from severe TBI registered in the Trauma Registry of the German Society for Trauma Surgery between 2002 and 2013 was undertaken.

Secretory Meningiomas: Characteristic Features and Clinical Management of a Unique Subgroup.

Secretory meningiomas (SM) represent a rare variant of the most common benign intracranial brain tumor. Defined by the histologic appearance of eosinophilic glandular formations and periodic-acidic Schiff-positive pseudopsammoma bodies, SM are characterized by unique molecular alterations, a disproportional occurrence of reactive peritumoral brain edema, and a clinical course that demands for increased awareness for perioperative complications. The frequent presence of extensive peritumoral edema has become a hallmark of SM and can be associated with life-threatening complications.

Pineal lesions: a multidisciplinary challenge.

The pineal region is a complex anatomical compartment, harbouring the pineal gland surrounded by the quadrigeminal plate and the confluents of the internal cerebral veins to form the vein of Galen. The complexity of lesions in that region, however, goes far beyond the pineal parenchyma proper. Originating in the pineal gland, there are not only benign cysts but also numerous different tumour types.

Case report: surviving a tiger attack.

Attacks on humans by large predators are rare, especially in Northern Europe. In cases of involvement of the craniocervical compartment, most of the attacks are not survived. We report on a case where the patient survived a tiger attack despite severe head trauma and discuss the circumstances leading to the patient's survival and excellent outcome.

Secretory meningiomas: a benign subgroup causing life-threatening complications.

While meningiomas are known as slow-growing extracerebral neoplasms, the subgroup of secretory meningiomas with histologically benign characteristics tend to cause disproportional peritumoral edema, frequently leading to severe medical and neurological complications in postoperative management. Among 1,484 meningiomas that were resected at our institution between 1990 and 2007, 44 (3%) patients were found to have the histological diagnosis of a secretory meningioma. The clinical course, radiological appearance, and histopathological features were retrospectively analyzed to examine the specifics of these benign lesions.

The translaminar approach to lumbar disc herniations impinging the exiting root.

Objective: We undertook a prospective, non-randomized study on the translaminar approach for the treatment of cephalad extruded disc fragments impinging the exiting root.

Methods: Between May 2000 and July 2004, 104 patients (59 men)-presenting with upper lumbar root compression in 74% of the cases -underwent a translaminar approach. The mean age was 57 years (range, 27-80 yr).
