Anatomy and physiology of cisternostomy
2016
Cisternostomy is defined as opening the basal cisterns to atmospheric pressure. This technique helps to reduce the intracranial pressure in severe head trauma as well as other conditions when the so-called sudden “brain swelling” troubles the surgeon. We elaborated the surgical anatomy of this procedure as well as the proposed physiology of how cisternostomy works. This novel technique may change the current trends in neurosurgery.
Conservative vs. Surgical Management of Post-Traumatic Epidural Hematoma: A Case and Review of Literature
2015
Patient: Male, 30 Final Diagnosis: Acute epidural hematoma Symptoms: — Medication: — Clinical Procedure: Observation Specialty: Neurosurgery Objective: Unusual clinical course Background: Trauma is the leading cause of death in people younger than 45 years and head injury is the main cause of trauma mortality. Although epidural hematomas are relatively uncommon (less than 1% of all patients with head injuries and fewer than 10% of those who are comatose), they should always be considered in evaluation of a serious head injury. Patients with epidural hematomas who meet surgical criteria and receive prompt surgical intervention can have an excellent prognosis, presumably owing to limited unde…
Blunt force trauma: an exceptional example of an ancient Egyptian mummy head
2019
In the course of a scientific cooperation between the German Mummy Project at the Reiss-Engelhorn-Museen, Mannheim (Germany) and the Musée National d'Histoire et d'Art Luxembourg (Luxembourg), an ancient Egyptian mummy head was analyzed using a multidisciplinary approach including radiocarbon dating, ultra-high resolution computed tomography, physical anthropology, forensic medicine and Egyptology. Dated to the Roman Period, the mummy head belonged to an upper-class woman between 25 and 35 years of age. Computed tomography revealed a lethal blunt force trauma affecting the dorsal parts of the parietal bones, below the intact overlaying soft tissue. Moreover, ancient medical treatment was ev…
Traumatic lesion of the extracranial vertebral artery--a note-worthy potentially lethal injury.
1994
The autopsy findings from routine neuropathological investigations of the cervical spine after any history of trauma emphasized the vulnerability of the extracranial vertebral arteries. In 21 cases with trauma to the head and neck, normal autopsy procedures did not succeed in revealing an obvious cause of death. Traumatic lesions of the spinal cord such as contusion or neurorrhexis were seen in 10 cases. In 15 cases we observed different degrees and stages of traumatic lesions of the extracranial vertebral arteries. Sudden death due to acute brain stem ischemia might be considered as an explanation in some of these cases. Six case reports with traumatic vertebral artery (VA) lesions after s…
Fatal and non-fatal injuries caused by crossbows
2002
Today in modern times, traumatic injuries caused by crossbows are a rarity. The largest collection of cases so far is presented in this study, consisting of four fatalities (two homicides and two suicides) and two non-fatal injuries (grievous bodily harm and an accident). All the victims were male having an age between 31 and 54. The weapons, which were used, were mainly high-performance precision crossbows with telescopic sights and hunting bolts. The parts of the body involved were the facial/head area in three of the cases and the thorax in three of them. There were either deep or total penetration injuries to the cranium and thorax with the bolt remaining in the wound in four out of six…
Guidelines for the Treatment of Head Injury in Adults
2017
AbstractThe workshop of scientific medical faculties (Arbeitsgemeinschaft wissenschaftlicher medizinischer Fakultäten [AWMF]) of Germany has asked societies of specific medical disciplines to jointly publish guidelines on the treatment of diseases and injuries. On behalf of the Deutsche Gesellschaft für Neurochirurgie, its commission on guidelines initiated an interdisciplinary approach to publish guidelines on the treatment of head injury in adults. These guidelines were published in German by the AWMF in late 2015. Because these guidelines have received widespread attention in Germany and became fundamental for research in head injuries, we have translated the German version into English …
False-Positive LSD Drug Screening Induced by a Mucolytic Medication
1998
Since the early 1990s, the ingestion of lysergic acid diethylamide (LSD) as an inexpensive alternative to amphetamine derivatives has once again become widespread (1)(2). Consequently, screening of LSD has gained importance in clinical routine. The drug screening of a patient with a severe craniocerebral trauma showed a positive LSD screening by the homogeneous immunoassay CEDIA® DAU LSD (Boehringer Mannheim). In spite of the 3-h half-life of LSD in plasma (3), the drug screening remained positive for several days. These samples …
The consequences of regulation of desat1 expression for pheromone emission and detection in Drosophila melanogaster.
2010
AbstractSensory communication depends on the precise matching between the emission and the perception of sex- and species-specific signals; understanding both the coevolutionary process and the genes involved in both production and detection is a major challenge. desat1 determines both aspects of communication—a mutation in desat1 simultaneously alters both sex pheromone emission and perception in Drosophila melanogaster flies. We investigated whether the alteration of pheromonal perception is a consequence of the altered production of pheromones or if the two phenotypes are independently controlled by the same locus. Using several genetic tools, we were able to separately manipulate the tw…
Besondere Kreislaufreaktionen im akuten Stadium der Sch�del-Hirnsch�digungen
1963
Die Kreislaufanalyse bei 1639 Schadel-Hirnverletzten im akuten Stadium hat ergeben, das echte Schocksyndrome mit schwerem Kreislaufkollaps auffallend selten zur Beobachtung gelangen und vorwiegend nur dann, wenn erheblichere Nebenverletzungen (abdominal, thoracal, Extremitaten) bestehen. Sehr viel haufiger ist dagegen eine sogenannte hypertonische Kreislaufreaktion im akuten Stadium zu sehen, insbesondere in Fallen mit einer alleinigen Schadel-Hirnschadigung (ohne anderweitige Nebenverletzungen). Der Schweregrad der hypertonischen Reaktion scheint in manchen Fallen der Schwere der Verletzung zu entsprechen, da systolische Druckanstiege um 200 mg Hg und mehr fast ausschlieslich in Fallen mit…
Time sequence and site of fluid accumulation in experimental neurogenic pulmonary edema.
1976
The initial phase of pulmonary edema development following intracranial pressure elevation was studied by means of transmission electron microscopy. Using perfusion fixation and application of a blood tracer (HRP horseradish peroxidase) the time sequence and site of fluid leakage out of pulmonary vessels was demonstrated: - passage of edema fluid through intercellular clefts of alveolar capillary endothelium - edema accumulation in alveolar interstitial tissue - draining of edema fluid from the alveolar septum to the interstitium of terminal bronchioli and to lymphatic vessels. An early interepithelial fluid leakage out of the alveolar wall remains questionable.
