1/136. Post-traumatic pituitary apoplexy--two case reports.A 60-year-old female and a 66-year-old male presented with post-traumatic pituitary apoplexy associated with clinically asymptomatic pituitary macroadenoma manifesting as severe visual disturbance that had not developed immediately after the head injury. skull radiography showed a unilateral linear occipital fracture. magnetic resonance imaging revealed pituitary tumor with dumbbell-shaped suprasellar extension and fresh intratumoral hemorrhage. Transsphenoidal surgery was performed in the first patient, and the visual disturbance subsided. decompressive craniectomy was performed in the second patient to treat brain contusion and part of the tumor was removed to decompress the optic nerves. The mechanism of post-traumatic pituitary apoplexy may occur as follows. The intrasellar part of the tumor is fixed by the bony structure forming the sella, and the suprasellar part is free to move, so a rotational force acting on the occipital region on one side will create a shearing strain between the intra- and suprasellar part of the tumor, resulting in pituitary apoplexy. Recovery of visual function, no matter how severely impaired, can be expected if an emergency operation is performed to decompress the optic nerves. Transsphenoidal surgery is the most advantageous procedure, as even partial removal of the tumor may be adequate to decompress the optic nerves in the acute stage. Staged transsphenoidal surgery is indicated to achieve total removal later.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/136. Human hypersensitivity angiitis: an uncommon cause of death after trauma.INTRODUCTION: The article demonstrates, using a case report, that death following an accident may have rarely encountered causes that are not a direct result of trauma and that can only be detected by autopsy. CASE: An unconscious woman aged 57 years was admitted to hospital. Despite immediate surgery for intracranial haemorrhage diagnosed by means of cranial computed tomography, the patient died showing clinical symptoms of circulatory depression after a brief period of stabilisation. The autopsy established myocardial infarction with hypersensitivity angiitis as the cause of death. CONCLUSION: In this case, the authors hold the opinion that the intravenous application of antibiotics during the patient's stay in hospital resulted in hypersensitivity angiitis. The factors causing hypersensitivity angiitis, the morphological picture (clinical, histological) and therapeutic measures are described.- - - - - - - - - - ranking = 41.842464535531keywords = intracranial haemorrhage, haemorrhage (Clic here for more details about this article) |
3/136. Phenoprocoumon, head trauma and delayed intracerebral haemorrhage.Delayed traumatic intracerebral haemorrhage (DTICH) constitutes a serious complication of head injury, and several studies have set out to identify predisposing clinical variables and appropriate management strategies.

4/136. The use of nasal endoscopy to control profuse epistaxis from a fracture of the basi-sphenoid in a seven-year-old child.A seven-year-old child sustained a fracture of her basisphenoid resulting in profuse, life-threatening haemorrhage which could not be controlled with a post-nasal pack. The fracture site was identified using rigid endoscopy and packed with oxidized cellulose, resulting in immediate control of the haemorrhage. The use of the nasal endoscope in the management of posterior epistaxis is discussed.- - - - - - - - - - ranking = 40.170226286478keywords = haemorrhage (Clic here for more details about this article) |

6/136. Management of severe postnasal haemorrhage: the Kingsley splint revisited.Postnasal haemorrhage accompanying severe craniofacial trauma may have catastrophic consequences if not arrested promptly. The airway has usually been secured and the cervical spine stabilized, but apart from fluid replacement, other attempts to control haemorrhage in the resuscitation room of the accident and emergency department may be to no avail. We wish to draw attention to a simple device that was introduced over 100 years ago and which may rapidly aid haemostasis and prevent the onset of hypovolaemic shock.- - - - - - - - - - ranking = 120.51067885943keywords = haemorrhage (Clic here for more details about this article) |
7/136. Head injury monitoring using cerebral microdialysis and Paratrend multiparameter sensors.INTRODUCTION: Following head injury complex pathophysiological changes occur in brain metabolism. The objective of the study was to monitor brain metabolism using the Paratrend multiparameter sensor and microdialysis catheters. patients, MATERIAL AND methods: Following approval by the Local ethics Committee and consent from the relatives, patients with severe head injury were studied using a triple bolt inserted into the frontal region, transmitting an intracranial pressure monitor, microdialysis (10 mm or 30 mm membrane; glucose, lactate, pyruvate, glutamate) catheter and Paratrend multiparameter (oxygen, carbon dioxide, pH and temperature) sensor. A Paratrend sensor was also inserted into the femoral artery for continuous blood gas analysis. RESULTS: 21 patients were studied with cerebral microdialysis for a total of 91 monitoring days (range 19 hours to 12 days). Of these, 14 patients were also studied with cerebral and arterial Paratrend sensors. The mean ( /- 95% confidence intervals) arterial and cerebral oxygen levels were 123 /- 10.9 mmHg and 27.9 /- 5.71 mmHg respectively. The arterial and cerebral carbon dioxide levels were 34.3 /- 2.35 mmHg and 45.3 /- 3.07 mmHg respectively. Episodes of systemic hypoxia and hypotension resulting in falls in cerebral oxygen and rises in cerebral carbon dioxide were rapidly detected by the arterial and cerebral Paratrend sensors. Systemic pyrexia was reflected in the brain with the cerebral Paratrend sensor reading 0.17 degree C (mean) higher than the arterial sensor. Elevations of cerebral glucose were detected, but the overall cerebral glucose was low (mean 1.57 /- 0.53 mM 10 mm membrane; mean 1.95 /- 0.68 mM 30 mm membrane) with periods of undetectable glucose in 6 patients. Lactate concentrations (mean 5.08 /- 0.73 mM 10 mm membrane; mean 8.27 /- 1.31 mM 30 mm membrane) were higher than glucose concentrations in all patients. The lactate/pyruvate ratio was 32.1 /- 5.16 for the 10 mm membrane and 30.6 /- 2.17 for the 30 mm membrane. Glutamate concentrations varied between patients (mean 15.0 /- 10.5 microM 10 mm membrane; mean 28.8 /- 17.8 microM 30 mm membrane). CONCLUSION: The combination of microdialysis catheters and Paratrend sensors enabling the monitoring of substrate delivery and brain metabolism, and the detection of secondary metabolic insults has the potential to assist in the management of head-injured patients.- - - - - - - - - - ranking = 4keywords = brain (Clic here for more details about this article) |
8/136. Traumatic occipital condyle fractures.Trauma to the brain or calvaria may cause some cranial nerve damage. This may be transitory or permanent. Occipital condyle fracture (OCF) is a rarely encountered pathology not easily diagnosed by routine clinical and radiological evaluation and one of the causes of lower cranial nerve disability. Frequently, the hypoglossal nerve is involved. Here we present two cases of OCF caused by motor vehicle accidents. Both of the patients complained of dysphagia and voice disturbance. After detailed neurologic and radiologic evaluation, they were diagnosed with OCF. They were both treated conservatively. OCF as a cause of lower cranial nerve damage is rarely reported. Since it is hard to diagnose OCF by routine cranial and cervical evaluation, detailed radiological study in suspected cases is a must. Since one of our patients was admitted 6 years after the trauma, this article is also noteworthy as a report on radiological changes of the OCF.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
9/136. Multiple growing fractures and cerebral venous anomaly after penetrating injuries: delayed diagnosis in a battered child.A growing fracture usually results from a skull fracture with dural tear after blunt head trauma during infancy. We present a case of child abuse with multiple growing fractures resulting from penetrating head trauma by scissors. MR imaging confirmed the presence of growing fractures and revealed a presumably post-traumatic venous anomaly (occluded left cavernous sinus and aberrant posterior venous drainage via the internal cerebral veins). Diagnosis of the growing fractures and venous anomaly was delayed until the age of 15 years. Medical expertise should be more readily available to battered children, and MR imaging is advocated in growing skull fracture to exclude associated post-traumatic brain lesions.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
10/136. titanium mesh repair of the severely comminuted frontal sinus fracture.BACKGROUND: Severely comminuted frontal sinus fractures are difficult to contour and immobilize. Frequently, plates or wires are inadequate in fixating all fragments together, resulting in less than optimal outcomes. Advancements in the development of biomaterials have now made titanium mesh a new option for the repair of severely comminuted fractures. methods: Fourteen patients with severely comminuted frontal sinus fractures were treated with titanium mesh from 1994 to 1999. The fractures were reduced and immobilized using a simple algorithm: (1) Isolated anterior table fractures were repaired with reduced bony fragments attached to titanium mesh. (2) Anterior table fractures with nasofrontal duct involvement were repaired by sinus obliteration and anterior wall reconstruction with reduced bony fragments attached to titanium mesh. (3) Anterior and posterior table fractures with cerebrospinal fluid leak or displacement were treated with the cranialization of the sinus and anterior wall reconstruction with reduced bony fragments attached to titanium mesh. RESULTS: Of the 14 patients treated, 12 were available for postoperative evaluation. Parameters such as nasal function, cranial nerve V and VII function, cosmesis, and complications (hardware extrusions, sinusitis, meningitis, osteomyelitis, mucopyocele, brain abscess, pneumocephalus, and cerebrospinal fluid leak) were evaluated. All patients had good function of the superior division of cranial nerves V and VII. Two patients (16%) had minor wound infections, which resolved under treatment with antibiotics. All had excellent cosmetic results as measured by postreduction radiographs and personal and family perceptions of forehead contour. CONCLUSION: titanium mesh reconstruction of severely comminuted frontal sinus fractures has few complications while providing excellent forehead contour and cosmesis.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
