    2011-01-01

    Full Text Available We present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture. Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts. In this paper, we describe the clinical and pathological findings. A brief review of published information on extramedullary hematopoiesis in subdural hematoma and the mechanisms of pathogenesis are also discussed. While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature. Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.

  2. Spontaneous subdural hematoma associated to Duret hemorrhage

    Full Text Available Subdural hematoma (SH is a neurosurgical emergency, usually caused by head trauma. Non-traumatic causes include aneurysm or arterial–venous malformation rupture, coagulopathy and others. We report the case of a 66 year-old man who developed apparently unprovoked signs of increased intracranial pressure. Brain computed tomography scan showed an acute spontaneous SH, surgically treated. Throughout surgery, a ruptured cortical artery with intensive bleeding appeared and was cauterized. After surgery, patient remained comatose and a new CT demonstrated Duret hemorrhage at the brainstem. Acute spontaneous SH of arterial origin is rare and highly lethal, in which a good prognosis relies on early diagnosis and treatment.

  3. Coexistent Intracerebral and Subdural Hemorrhage : A case Report

    Full Text Available Subdural and Intracerebral Hemorrhage, occuring simultaneously in a patient is a very rare condition. The few case reports found in literature occurred in situations of trauma, coagulopathy, CNS malignancy and in dialysis dependant patients. We report one such case where both conditions coexisted, in the background of poorly controlled hypertension. The possible pathogenesis in this case is discussed.

    Although urgent surgical hematoma evacuation is necessary for most patients with subdural hematoma (SDH), well-orchestrated, evidenced-based, multidisciplinary, postoperative critical care is essential to achieve the best possible outcome. Acute SDH complicates approximately 11% of mild to moderate traumatic brain injuries (TBIs) that require hospitalization, and approximately 20% of severe TBIs. Acute SDH usually is related to a clear traumatic event, but in some cases can occur spontaneously. Management of SDH in the setting of TBI typically conforms to the Advanced Trauma Life Support protocol with airway taking priority, and management breathing and circulation occurring in parallel rather than sequence.

    Full Text Available Spinal (subarachnoid anesthesia (SA is a widely used general-purpose anesthesia. Postdural Puncture Headaches (PDPHs represent one of the principal complications of spinal anesthesia. A 21-year-old man underwent inguinal herniorrhaphy and orchiectomy using spinal anesthesia. Postoperatively, our patient started to have a headache with nausea. The patient received symptomatic therapy, but the severe headache persisted even in the supine position, with his vital signs and neurological examination being normal. Cranial MRI showed a bilateral subdural hematoma from his frontal to temporal region. A postdural puncture headache is a frequent complication after spinal anesthesia. However, serious complications, such as an intracranial subdural hemorrhage, can rarely occur. [Arch Clin Exp Surg 2015; 4(1.000: 54-56

  6. Retroocular and Subdural Hemorrhage or Hemosiderin Deposits in Pediatric Autopsies.

    Del Bigio, Marc R; Phillips, Susan M

    2017-04-01

    The presence of hemosiderin in the optic nerve sheath and/or retina is sometimes used to estimate the timing of injury in infants or children with suspected non-accidental head trauma. To determine the prevalence of hemosiderin in deaths not associated with trauma, we performed a prospective study of retroocular orbital tissue, cranial convexity, and cervical spinal cord dura mater in infants and children hemosiderin within the orbital fat, ocular muscles, and parasagittal cranial and/or cervical spinal subdural compartment. This bleeding is likely a consequence of the birth process. None had evidence of hemorrhage within the optic nerve sheath. Premature birth was less likely associated with orbital tissue hemorrhage. Caesarean section birth (mainly nonelective) was not associated with lower prevalence. Residual hemosiderin was identifiable up to 36 weeks postnatal age, suggesting gradual disappearance after birth. Cardiopulmonary resuscitation (performed in the majority of cases) was not associated with acute hemorrhage. In 9 traumatic deaths, 6 had blood and/or hemosiderin within the optic nerve sheath. Knowledge of the potential presence and resolution of hemosiderin in these locations is important for medicolegal interpretation of childhood deaths associated with head or brain injury. © 2017 American Association of Neuropathologists, Inc.

    2013-01-01

    Full Text Available The aim of this study is to report a case of spontaneous intracranial hypotension complicated by bilateral subdural hemorrhage that resolved with conservative management. A young male presented with severe orthostatic headache associated with dizziness, neck pain and diplopia. Brain imaging revealed characteristic pachymeningeal enhancement and bilateral subdural hemorrhage. Radionuclide cisternography confirmed the Cerebrospinal fluid leak at the cervical 5 and cervical 6 vertebral level. He had clinical and radiological resolution with bed rest, hydration and analgesics and has remained symptom free since then. Spontaneous intracranial hypotension may be complicated by bilateral subdural hemorrhage. A conservative treatment approach is a viable option, as it may help improve the clinical and radiological outcome, especially when interventional facilities are not available.

  8. Subdural hemorrhage: A unique case involving secondary vitamin K deficiency bleeding due to biliary atresia.

    Extrahepatic biliary atresia (EHBA) is a rare disease characterized by progressive and obliterative cholangiopathy in infants and is one of the major causes of secondary vitamin K deficiency bleeding (VKDB) due to cholestasis-induced fat malabsorption. Breast feeding increases the tendency of bleeding in EHBA patients because breast milk contains low amounts of vitamin K. A 2-month-old female infant unexpectedly died, with symptoms of vomiting and jaundice prior to death. She had been born by uncomplicated vaginal delivery and exhibited normal growth and development with breastfeeding. There was no history of trauma. She received vitamin K prophylaxis orally. In an emergency hospital, a CT scan showed a right intracranial hematoma and mass effect with midline shift to the left. In the postmortem examination, severe atresia was observed in the whole extrahepatic bile duct. Histologically, cholestasis, periductal fibrosis, and distorted bile ductules were noted. The gallbladder was not identified. A subdural hematoma and cerebellar tonsillar herniation were found; however, no traumatic injury in any part of the body was observed. Together, these findings suggest that the subdural hemorrhage was caused by secondary vitamin K deficiency resulting from a combination of cholestasis-induced fat malabsorption and breastfeeding. Subdural hemorrhage by secondary VKDB sometimes occurs even when vitamin K prophylaxis is continued. This case demonstrated that intrinsic factors, such as secondary VKDB (e.g., EHBA, neonatal hepatitis, chronic diarrhea), should also be considered in infant autopsy cases presenting with subdural hemorrhage.

    2012-03-01

    Full Text Available Abstract Introduction Spinal anesthesia is a widely used general purpose anesthesia. However, serious complications, such as intracranial subdural hemorrhage, can rarely occur. Case presentation We report the case of a 73-year-old Japanese woman who had acute onset of intracranial subdural hemorrhage five days after spinal anesthesia for knee arthroscopic surgery. Conclusion This case highlights the need to pay attention to acute intracranial subdural hemorrhage as a complication after spinal anesthesia. If the headache persists even in a supine position or nausea occurs abruptly, computed tomography or magnetic resonance imaging of the brain should be conducted. An intracranial subdural hematoma may have a serious outcome and is an important differential diagnosis for headache after spinal anesthesia.

    Intradural extramedullary cavernous angiomas of the central nervous system are a rare type of cavernous angioma, but they can cause fatal subarachnoid hemorrhage. The efficacy of resection for this type of cavernous malformations remains uncertain. This is the first report to recommend surgical resection of these types of lesions regardless of the fatal condition. Our patient was a 70-year-old Japanese man who experienced a sudden onset of an occipital headache, followed by bilateral abducens nerve palsy. Magnetic resonance imaging revealed a small amount of hemorrhage in both of the lateral ventricles and an intradural extramedullary mass lesion in the left side of his foramen magnum. Two weeks after the appearance of initial symptoms, he became comatose. A computed tomography scan showed an increase in the subarachnoid intraventricular hemorrhaging and of the acute hydrocephalus. Following ventricular drainage, total tumor resection was performed using the lateral suboccipital transcondylar approach in conjunction with a first cervical hemilaminectomy. We observed a grape-like vascular-rich tumor with calcification that was adhering tightly to the wall of his left vertebral artery. A histopathological examination of the surgery specimen identified it as a cavernous angioma. After placement of a ventriculoperitoneal shunt and 2 months of rehabilitation, he recovered completely. An intradural extramedullary foramen magnum cavernous malformation is quite rare. The fragile surface of our patient's lesion was causing repeated subarachnoid hemorrhage and consequently progressive fatal neurological deterioration. Surgical resection of the lesion to prevent repeated hemorrhage was performed and he recovered fully. Therefore, we recommend surgical resection of the lesion regardless of the potentially fatal condition.

    The risk of sport-related concussion (SRC) has emerged as a major public health concern. In rare instances, sport-related head injuries can be even more severe, such as subdural hemorrhage, epidural hemorrhage, or malignant cerebral edema. Unlike SRCs, sport-related structural brain injury (SRSBI) is rare, may require neurosurgical intervention, and can lead to permanent neurologic deficit or death. Data characterizing SRSBI are limited, and many have recognized the need to better understand these catastrophic brain injuries. The goal of the current series is to describe, in detail, the presentation, management, and outcomes of examples of these rare injuries. During the fall of 2015, three high school football players presented with acute subdural hemorrhages following in-game collisions and were treated at our institution within a span of 2 months. For the 2 athletes who required surgical intervention, a previous SRC was sustained within 4 weeks before the catastrophic event. One year after injury, 2 players have returned to school, though with persistent deficits. One patient remains nonverbal and wheelchair bound. None of the athletes has returned to sports. Acute subdural hemorrhage resultant from an in-game football collision is rare. The temporal proximity of the reported SRSBIs to recent SRCs emphasizes the importance of return-to-play protocols and raises questions regarding the possibility of second impact syndrome. Although epidemiologic conclusions cannot be drawn from this small sample, these cases provide a unique opportunity to demonstrate the presentation, management, and long-term outcomes of SRSBI in American high school football.

  12. Challenging the Pathophysiologic Connection between Subdural Hematoma, Retinal Hemorrhage and Shaken Baby Syndrome

    Directory of Open Access Journals (Sweden)

    Gabaeff, Steven C

    2011-05-01

    Full Text Available Child abuse experts use diagnostic findings of subdural hematoma and retinal hemorrhages as near-pathognomonic findings to diagnose shaken baby syndrome. This article reviews the origin of this link and casts serious doubt on the specificity of the pathophysiologic connection. The forces required to cause brain injury were derived from an experiment of high velocity impacts on monkeys, that generated forces far above those which might occur with a shaking mechanism. These forces, if present, would invariably cause neck trauma, which is conspicuously absent in most babies allegedly injured by shaking. Subdural hematoma may also be the result of common birth trauma, complicated by prenatal vitamin D deficiency, which also contributes to the appearance of long bone fractures commonly associated with child abuse. Retinal hemorrhage is a non-specific finding that occurs with many causes of increased intracranial pressure, including infection and hypoxic brain injury. The evidence challenging these connections should prompt emergency physicians and others who care for children to consider a broad differential diagnosis before settling on occult shaking as the de-facto cause. While childhood non-accidental trauma is certainly a serious problem, the wide exposure of this information may have the potential to exonerate some innocent care-givers who have been convicted, or may be accused, of child abuse.

    2012-10-01

    Bilateral congenital vocal fold paralysis (BVFP) may result from multiple etiologies or remain idiopathic when no real cause can be identified. If obstructive dyspnea is significant and requires urgent stabilization of the airway, then intubation is performed first and an MRI of the brain is conducted to rule out an Arnold-Chiari malformation that can benefit from a shunt procedure and thus alleviate the need for a tracheostomy. Clinically silent subdural hemorrhage without any birth trauma represents another cause of neonatal BVFP that resolves spontaneously within a month. It is of clinical relevance to recognize this potential cause of BVFP as its short duration may alleviate the need for a tracheostomy. In this article, we present such a case and review the literature to draw the otolaryngologist's attention to this possible etiology. Copyright © 2012. Published by Elsevier Ireland Ltd.

  14. MRI Findings of Early-Stage Hyperacute Hemorrhage Causing Extramedullary Compression of the Cervical Spinal Cord in a Dog with Suspected Steroid-Responsive Meningitis-Arteritis

    2017-09-01

    Full Text Available A 9-month-old female Weimaraner was presented to the emergency service due to episodes of fever and neck pain. Physical examination revealed a stiff neck posture and elevated body temperature. Shortly after clinical examination was performed, the dog developed peracute onset of non-ambulatory tetraparesis compatible with a C1–C5 spinal cord (SC lesion. Immediately thereafter (<1 h, MRI of the cervical SC was performed with a 3-T scanner. A left ventrolateral intradural-extramedullary SC compression caused by a round-shaped structure at the level of C3––C4 was evidenced. The structure was iso- to slightly hyperintense in T1-weighted (T1W sequences compared to SC parenchyma and hyperintense in T2-weighted, gradient echo, and fluid-attenuated inversion recovery. Moreover, the structure showed a strong homogeneous contrast uptake in T1W sequences. Cerebrospinal fluid (CSF analysis revealed a mixed pleocytosis, as well as elevated protein and erythrocyte count. Early-stage hyperacute extramedullary hemorrhage was suspected due to immune mediated vasculitis. The dog was maintained under general anesthesia and artificial ventilation for 24 h and long-term therapy with corticosteroids and physiotherapy was initiated. Eight weeks after initial presentation, the dog was ambulatory, slightly tetraparetic. Follow-up MRI showed a regression of the round-shaped structure and pleocytosis was not evident in CSF analysis. This report describes an early-stage hyperacute extramedullary hemorrhage, a condition rarely recorded in dogs even in experimental settings.

  15. Acute Subdural Hematoma and Subarachnoid Hemorrhage Caused by Ruptured Cortical Artery Aneurysm: Case Report and Review of Literature

    Ahmad Shekarchizadeh

    2017-01-01

    Full Text Available The present report describes an acute subdural hematoma (ASDH associated with subarachnoid hemorrhage (SAH, due to ruptured cortical aneurysm. To our knowledge, extremely rare cases of this sort have been reported so far. A 23-year-old male patient without previous trauma presented with severe headache and rapidly decreasing level of consciousness to decerebrate status. Computed tomography (CT scan has demonstrated an ASDH together with SAH. Hematoma has immediately been evacuated without any evaluation by angiography. After evacuation of the thick subdural clot, a 10-mm aneurysm was revealed on a precentral artery of frontal cortex, which was ligated. However, after 35 days the patient discharged with left side hemiparesis and dysphasia, and just after several months of admission he got symptom free. Ruptured cortical aneurysm should be considered as one of the causes of spontaneous ASDH. Vascular anomaly investigations are suggested for these cases, thus CT angiography or digital subtraction angiography has to be considered if clinical condition allows.

    Full Text Available Chronic subdural hematoma of the posterior fossa is an uncommon entity, and spontaneous lesions are very rarely described, occurring mostly during anticoagulation therapy. The association of the posterior fossa chronic subdural hematoma with spontaneous parenchymal hemorrhage without anticoagulation therapy was never related in the literature, to our knowledge. We describe a case of a 64 year-old woman who suffered a spontaneous cerebellar hemorrhage, treated conservatively, and presented 1 month later with a chronic subdural posterior fossa hematoma.Hematomas subdurais da fossa posterior são lesões raras, mais comumente relacionadas com traumas graves. A ocorrência de hematomas subdurais crônicos na fossa posterior é muito rara, sendo descritos 15 casos até o momento, boa parte relacionada ao uso de anticoagulantes. Em nossa revisão da literatura, não pudemos encontrar nenhum relato da associação entre hematoma subdural crônico da fossa posterior e hemorragia cerebelar espontânea. Relatamos o caso de paciente de 64 anos com hematoma intraparenquimatoso cerebelar tratado conservadoramente e hematoma subdural crônico, tratado cirurgicamente, cerca de 1 mês após o acidente vascular cerebelar.

    In addition to rostrocaudal spreading of bloody components in the subdural space, rupture of the hematoma into the subarachnoid space must have released pressure, compressing the spinal cord. In this case report, we also describe the serial MRI studies and note the limitations of the resolution of spinal MRI in the acute phase.

    2017-11-03

    OBJECTIVE Children who have subdural hematomas (SDHs) with no or minimal neurological symptoms (SDH-mild symptoms) often present a forensic challenge. Nonabusive causes of SDH, including birth-related SDH, benign enlargement of the subarachnoid spaces (BESS), and other proposed causes have been offered as etiologies. These alternative causes do not provide explanations for concomitant suspicious injuries (CSIs). If SDH with mild symptoms in young children are frequently caused by these alternative causes, children with SDH-mild symptoms should be more likely to have no other CSIs than those who have SDH with severe symptoms (SDH-severe symptoms). Additionally, if SDH with mild symptoms is caused by something other than abuse, the location and distribution of the SDH may be different than an SDH caused by abuse. The objectives of this study were to determine the prevalence of other CSIs in patients who present with SDH-mild symptoms and to compare that prevalence to patients with SDH-severe symptoms. Additionally, this study sought to compare the locations and distributions of SDH between the two groups. Finally, given the data supporting BESS as a potential cause of SDH in young children, the authors sought to evaluate the associations of BESS with SDH-mild symptoms and with other CSIs. METHODS The authors performed a 5-year retrospective case-control study of patients younger than 2 years of age with SDH evaluated by a Child Abuse Pediatrics program. Patients were classified as having SDH-mild symptoms (cases) or SDH-severe symptoms (controls). The two groups were compared for the prevalence of other CSIs. Additionally, the locations and distribution of SDH were compared between the two groups. The presence of BESS was evaluated for associations with symptoms and other CSIs. RESULTS Of 149 patients, 43 presented with SDH-mild symptoms and 106 with SDH-severe symptoms. Patients with SDH-mild symptoms were less likely to have other CSIs (odds ratio [OR] 0.2, 95

  1. Nasal septum extramedullary plasmacytoma

    Full Text Available Introduction. Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone - solitary osseous plasmacytoma, or in soft tissue - extramedullary plasmacytoma (EMP. EMP represents less than 1% of all head and neck malignancies. Case report. We presented a case of EMP of the nasal septum in a 44-year-old male who had progressive difficulty in breathing through the nose and frequent heavy epistaxis on the right side. Nasal endoscopy showed dark red, soft, polypoid tumor in the last third of the right nasal cavity arising from the nasal septum. The biopsy showed that it was plasmacytoma. Bence Jones protein in the urine, serum electrophoresis, bone marrow biopsy, skeletal survey and other screening tests failed to detect multiple myeloma. This confirmed the diagnosis of EMP. The mass was completely removed via an endoscopic approach, and then, 4 week later, radiotherapy was conducted with a radiation dose of 50 Gray. No recurrence was noted in a 3-year follow- up period. Conclusion. EMP of the nasal cavity, being rare and having long natural history, represents a diagnostic and therapeutic challenge for any ear, nose and throat surgeon. Depending on the resectability of the lesion, a combined therapy is the accepted treatment.

    Subdural empyema is a known disease entity; however, calcified subdural empyema is uncommon. The authors present a case of an 11-year-old boy in whom there was diagnosed a chronic calcified subdural empyema 10 years after an attack of meningitis. The patient had suffered from generalized tonic clonic seizures occurring 2-6 times in a month. A large fronto-temporo-parietal craniotomy was carried out and the subdural empyema filled with numerous uncharacteristic tissue fragments with thick pus together with the partially calcified and ossified capsule was removed. The empyema mass was found to be sterile for bacteria. After the operation, no epileptic seizure occurred and the boy is on sodium valporate. We must emphasize the unusual occurrence of the chronic subdural empyema presenting with calcification-ossification and large size as observed in our case.

    Full Text Available Extramedullary plasmacytoma (EMP is a rare plasma cell neoplasm of soft tissue without bone marrow involvement or other systemic characteristics of multiple myeloma. It accounts for 3% of all plasma cell tumors. Multiple extramedullary plasmacytoma is defined when there is more than one extramedullary tumor of clonal plasma cells and such presentation has not been described earlier. We report such rare case of multiple extramedullary plasmacytoma involving multiple soft tissues in chest, abdomen, mandible, maxilla, and gingiva.

    Full Text Available History of present illness: A 21-year-old female with no past medical history presented to the ED after multiple tonic-clonic seizures over the previous 12 hours, the longest lasting 20 seconds. She returned to baseline after each seizure, had no obvious signs of trauma, and did not exhibit any focal neurologic deficits. She denied illicit drugs or new medications. A family member noted that she had fallen from her bed (approximately 3 feet high 2 days ago. Significant findings: Non-contrast Computed Tomography (CT of the Head showed a dense extra-axial collection along the left frontal and parietal regions, extending superior to the vertex with mild mass effect, but no midline shift. Discussion: Intracranial hemorrhage (ICH is a term to describe any abnormal bleeding within the bony confines of the skull. Most commonly, subdural hemorrhages (SDH result from injury to the bridging veins that lead to bleeding between the dura and arachnoid maters. However, in 20%-30% of cases an arterial source of bleeding can be found.1 For adults, motor vehicle collisions and other unintentional head trauma are typically the provoking factors in developing SDH. Falls in the elderly are a common cause of SDH since diffuse cerebral atrophy leads to increased shear forces upon vasculature structures during the fall. The risk of SDH increases with the use of anti-thrombotic agents.2 Clinical presentation varies from asymptomatic to coma (in 50 percent of acute SDH. Chronic SDH may present with headaches, light-headedness, cognitive impairment, and seizures.1 The risk of posttraumatic epileptic seizures (PTS is higher in acute SDH. Risk factors for acute SDH PTS include low Glasgow Coma Score and craniotomy, whereas risk factors for PTS in chronic SDH include alcohol abuse, change in mental status, previous stroke, and hematoma density on CT.3 CT is the most widely used imaging modality for identifying ICH. Acute SDH (within 1-2 days are visualized as hyperdense

    2014-08-01

    To (1) synthesize the terminology used to classify extramedullary spinal cysts in dogs to clarify some of the commonly reported misconceptions, and (2) propose a classification scheme to limit confusion with terminology. Literature review. An online bibliographic search was performed in January 2013 for articles relating to extramedullary spinal cysts in dogs using PubMed (http://www.pubmed.gov/) and Google Scholar (http://scholar.google.com/) databases. Only peer-reviewed clinical literature describing cystic lesions pertaining to the spinal cord and associated structures was included. From 1962 to 2013, 42 articles were identified; 25 (95 dogs) reported meningeal cysts, 10 (24 dogs) described 60 extradural cysts, 3 reports (18 dogs) described discal cysts or acute compressive hydrated nucleus pulposus extrusions (HNPE). Spinal cysts were categorized by location based on cross-sectional imaging as meningeal or extradural non-meningeal. Sub-classification was then performed based on surgical findings and pathology. Meningeal cysts included arachnoid diverticulae and Tarlov (perineural) cysts. Extradural non-meningeal cysts included intraspinal cysts of the vertebral joints, ligaments and discs. Discal cysts also fit this category and have been reported extensively in humans but appear rare in dogs. Extramedullary spinal cysts should be first classified according to location with a sub-classification according to pathologic and surgical findings. Previous canine cases of discal cysts appear to represent a different disease entity and the term acute compressive HNPE is therefore preferred. © Copyright 2014 by The American College of Veterinary Surgeons.

    Extramedullary plasmacytoma (EMP) is a rare entity that belongs to the category of non-Hodgkin lymphoma. EMP make up 4% of all plasma cell tumors and occur mainly in the upper aerodigestive tract. Primary plasmacytoma involving the orbit is rare. There is a relation between solitary plasmacytoma and subsequent development of multiple myeloma. As no predictors of progression have been identified patients need indefinite follow-up. The authors report a case of EMP involving the eyelid in an otherwise healthy adult female.

    Capillary hemangiomas are common benign vascular tumors on skin and soft tissues, but developing as an intradural and extramedullary (IDEM) tumor in spine is extremely rare. In this report, we present IDEM tumor compressing thoracic cord in T2-3 level with extensive arachnoiditis below the tumor level in a 60-year-old man. The lesion was removed and histological diagnosis was capillary hemangioma. Prompt diagnosis and resection are important to avoid neurological deterioration from acute hemorrhagic condition. Simultaneous arachnoiditis may be originated from old subarachnoid hemorrhage associated tumor before diagnosis, and we suggest it as a helpful diagnostic feature to suspect vascular tumors such as capillary hemangioma.

    The labour course, treatment, and prognoses were discussed concerning four mature newborn infants with intracranial hemorrhage diagnosed by CT. Of intracranial hemorrhage, 70.7% was small hemorrhage along the cerebellar tentorium and the falx cerebri, 12.2% subdural hemorrhage in the posterior cranial fossa, and 9.8% subdural hemorrhage in the fornex. Intraventricular or extradural hemorrhage was rarely found. The prognosis is determined by the severity of neurotic symptoms due to cerebral hypoxia. Subdural hemorrhage of the posterior cranial fossa resulted in cerebral palsy in one fifth of the cases, and in slight enlargement of the ventricle in three fifths. Subdural hematoma left porencephaly in one fourth of the patients, but the remaining recovered to normal.

    Full Text Available Acute posterior fossa subdural hematomas are rare and most of them are trauma-related. Non-traumatic ones have been reported in patients who had idiopathic thrombocytopenic purpura or those who had been receiving anticoagulant therapy. We report on the case of 57-year-old Iranian man who developed sudden severe occipital headache, drowsiness, repeated vomiting, and instability of stance and gait. He was neither hypertensive nor diabetic. No history of head trauma was obtained and he denied illicit drug or alcohol ingestion. A preliminary diagnosis of acute intra-cerebellar hemorrhage was made. His CT brain scan revealed an acute right-sided, extra-axial, crescent-shaped hyperdense area at the posterior fossa. His routine blood tests, platelets count, bleeding time, and coagulation profile were unremarkable. The patient had spontaneous acute infratentorial subdural hematoma. He was treated conservatively and discharged home well after 5 days. Since then, we could not follow-up him, clinically and radiologically because he went back to Iran. Our patient’s presentation, clinical course, and imaging study have called for conservative management, as the overall presentation was relatively benign. Unless the diagnosis is entertained and the CT brain scan is well-interpreted, the diagnosis may easily escape detection.

    Acute subdural hematoma (ASDH) is a frequent complication of severe head injury, whose secondary ischemic lesions are often responsible for the severity of the disease. We focused on the differences of secondary ischemic lesions caused by the components, 0.4ml venous- or arterial-blood, or saline, infused in the subdural space, evaluating the differences in vivo model, using rats. The saline infused rats are made for elderly atrophic brain with subdural effusion (SDE) model. Our data showed that subdural blood, both venous- and arterial-blood, aggravate brain edema and lesion development more than SDE. This study is the first study, in which different fluids in rats' subdural space, ASDH or SDE are compared with the extension of early and delayed brain damage by measuring brain edema and histological lesion volume. Blood constituents started to affect the degree of ischemia underneath the subdural hemorrhage, leading to more pronounced breakdown of the blood-brain barrier and brain damage. This indicates that further strategies to treat blood-dependent effects more efficiently are in view for patients with ASDH. Copyright © 2017 Elsevier B.V. All rights reserved.

    To report the imaging appearances of mass-like extramedullary hematopoiesis (EMH), to identify those features that are sufficiently characteristic to allow a confident diagnosis, and to recognize the clinical conditions associated with EMH and the relative incidence of mass-like disease. We retrospectively identified 44 patients with EMH; 12 of which (27%) had focal mass-like lesions and formed the study group. The study group consisted of 6 male and 6 female subjects with a mean age of 58 years (range 13-80 years). All 12 patients underwent CT imaging and 3 of the 12 patients had undergone additional MR imaging. The imaging characteristics of the extramedullary hematopoiesis lesions in the study group were analyzed and recorded. The patient's clinical presentation, including any condition associated with extramedullary hematopoiesis, was also recorded. Ten of the 12 (83%) patients had one or more masses located along the axial skeleton. Of the 10 patients with axial masses, 9 (90%) had multiple masses and 7 (70%) demonstrated internal fat. Eight patients (80%) had paraspinal masses and 4 patients (40%) had presacral masses. Seven patients (70%) had splenomegaly. Eleven of the 12 patients had a clinical history available for review. A predisposing condition for extramedullary hematopoiesis was present in 10 patients and included various anemias (5 cases; 45%), myelofibrosis/myelodysplastic syndrome (4 cases; 36%), and marrow proliferative disorder (1 case; 9%). One patient had no known predisposing condition. Mass-like extramedullary hematopoiesis most commonly presents as multiple, fat-containing lesions localized to the axial skeleton. When these imaging features are identified, extramedullary hematopoiesis should be strongly considered, particularly when occurring in the setting of a predisposing medical condition. (orig.)

  17. Extramedullary hematopoiesis in murine schistosomiasis mansoni

    Directory of Open Access Journals (Sweden)

    H. L. Lenzi

    1995-04-01

    Full Text Available During Schistosoma mansoni infection, there is morphological evidence of involvement of various hematopoietic growth factors, which cause eosinophil, neutrophil, megakaryocytic and erythroid extramedullary foci in the liver, lymph nodes and omental and mesenteric milky spots. While the eosinophil metaplasia in the periphery of hepatic granulomas roughly reproduced the intensity of the medullary eosinopoiesis, the neutrophil metaplasia, on the contrary, was more intense during the period of neutrophil depression in the bone marrow. This fact suggests that extramedullary hematopoietic foci are locally regulated, and amplify and/or compensate the systemic hematopoietic response during the infection.

    Full Text Available Hereditary spherocytosis (HS is a common inherited hemolytic anemia due to red cell membrane defects. Extramedullary hematopoiesis is a compensatory response to insufficient bone marrow blood cell production. The preferred sites of extramedullary hematopoietic involvement are the spleen, liver and lymph nodes; but in HS, the posterior paravertebral mediastinum is also commonly involved. We report a case of a 50-year-old male who presented to us in respiratory distress and with bilateral paravertebral posterior mediastinal masses, which on trucut biopsy were found to be extra-hematopoietic masses; and the patient was found to have hereditary spherocytosis.

  20. Mozart's chronic subdural hematoma.

    Science.gov (United States)

    Drake, M E

    1993-11-01

    No commemoration of the bicentennial of Mozart's death would be complete without some consideration of that premature yet predictable demise. Mozart's premonitions of death are well known and apparently played a role in the composition of the K.626 Requiem and perhaps other works. His death has traditionally been ascribed to infectious causes, chiefly rheumatic fever or post-streptococcal glomerulonephritis, exacerbated by intemperance and chronic penury. Pathology has been difficult because of his supposed burial in a pauper's grave, the location and contents of which were later supposedly lost. Mozart's burial place in St. Mark's Cemetery in Vienna was known and, in the parlance of the day, "reorganized" a decade later, as the occupants of plots were disinterred to make room for the more recently decreased. A skull believed to the Mozart's was saved by the successor of the gravedigger who had supervised Mozart's burial, and then passed into the collections of the anatomist Josef Hyrtl, the municipality of Salzburg, and the Mozarteum museum (Salzburg). Forensic reconstruction of soft tissues related to this skull reveals substantial concordance with Mozart's portraits. The skull suggests premature closure of the metopic suture, which has been suggested on the basis of his physiognomy. A left temporal fracture and concomitant erosions raise the question of chronic subdural hematoma, which would be consistent with several falls in 1789 and 1790 and could have caused the weakness, headaches, and fainting he experienced in 1790 and 1791. Aggressive bloodletting to treat suspected rheumatic fever could have decompensated such a lesion to produce his death on December 5, 1791.

    We present a comparative CT and MRI study of the paraspinal extramedullary hematopoiesis in 32 thalassemic patients. The patients were classified into four groups according to the MRI and CT imaging findings. Active recent extramedullary paraspinal hematopoietic masses show soft tissue behavior in both CT and MRI. Older inactive masses reveal iron deposition or fatty replacement. Combined imaging findings of paraspinal extramedullary hematopoiesis revealed the phase of its evolution and the correct diagnosis.

    Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein, we report the imaging findings of beta-thalassemia in a 13-year-old boy complaining of weakness of left side of the body and gait disturbance; CT and MRI revealed an extradural mass in the right temporoparietal region.

    The dura is traditionally viewed as a supportive fibrous covering of the brain containing the dural venous sinuses but otherwise devoid of vessels and lacking any specific function. However, review of the embryology and anatomy reveals the dura to be a complex, vascularized and innervated structure, not a simple fibrous covering. The dura contains an inner vascular plexus that is larger in the infant than in the adult, and this plexus likely plays a role in CSF absorption. This role could be particularly important in the infant whose arachnoid granulations are not completely developed. Although subdural hemorrhage is frequently traumatic, there are nontraumatic conditions associated with subdural hemorrhage, and the inner dural plexus is a likely source of bleeding in these nontraumatic circumstances. This review outlines the development and age-specific vascularity of the dura and offers an alternative perspective on the role of the dura in homeostasis of the central nervous system. (orig.)

    To determine the role of fine needle aspiration cytology in the diagnosis of extramedullary plasmacytoma. The study group consisted of 13 patients with palpable masses at various sites. The tumors were aspirated for cytologic study. The smears revealed groups of mature and immature plasma cells at various stages of maturation. Mature plasma cells showed an eccentric nucleus and abundant, deep, basophilic cytoplasm with a paranuclear halo. Plasmablasts (immature plasma cells) showed a prominent, eccentric nucleus with single, large nucleolus and abundant, deep, basophilic cytoplasm with no paranuclear halo. Binucleate and multinucleate forms were also seen quite often. The tumors were excised, and the histologic sections confirmed the cytologic diagnosis. All the patients received radiotherapy. One patient (18 years old) developed recurrence and died due to extensive infiltration into the maxilla and mandible. Two patients (57 and 62 years) developed multiple myeloma one to two years after the excision of tumors, and both died two to three months later. The remaining 10 patients were alive and well at this writing. The smears from all 13 patients were diagnosed as extramedullary plasmacytomas by fine needle aspiration cytology.

    Calcified or ossified chronic subdural hematoma is a rare entity that usually presents as a space-occupying lesion over the cerebral convexity. We report a case of calcified and ossified chronic subdural hematoma in an unusual location that has not been previously reported. A 24-year-old man with a history of tonic-clonic convulsions since 7 months of age was admitted because of increasing frequency and duration of seizures. Computed tomography and magnetic resonance imaging demonstrated a fusiform extra-axial lesion just above the tentorium and adjacent to the cerebral falx. A calcified and ossified chronic subdural hematoma was noted and was almost completely removed by craniotomy. Better seizure control was achieved by removal of the calcified chronic subdural hematoma. Calcified subdural hematoma, calcified epidural hematoma, calcified empyema, meningioma, calcified arachnoid cyst, and calcified convexity of the dura mater with acute epidural hematoma should be considered for the differential diagnosis of an extra-axial calcified lesion.

    To review the histories of extramedullary plasmacytoma patients diagnosed in Slovenia between 1969 and 1999, to determine the relationship between radiotherapy (XRT) dose and local tumor control, and to clarify the role of elective nodal XRT and the prognostic value of Bartl's histologic grading criteria (originally devised for multiple myeloma [MM]). The database of the Cancer Registry of Slovenia was used for the identification of patients. The inclusion criteria were as follows: bone marrow biopsy showing less than 10% plasma cells, normal skeletal survey, and immunohistochemically determined tumor monoclonality. Simulation/portal films were reviewed to assess the extent of elective nodal XRT. Twenty-six patients with 31 tumors fulfilled the inclusion criteria. In 4 patients, nine metachronously appearing solitary tumors were diagnosed. The head-and-neck region and other body sites were the sites of origin of primary tumors in 84% and 16% of patients, respectively, whereas in the two regions, regional disease was seen in 15% and 60% of patients, respectively. Therapy was as follows: XRT, 12 patients; surgery and postoperative XRT, 15 patients; and surgery, 4 patients. Ultimate local and regional control rates were 90% and 97%, respectively, and MM developed in 2 (8%) patients. The 10-year disease-specific and overall survival rates were 87% and 61%, respectively. The analysis of the dose-effect relationship showed that more conservative treatment is justified: for macroscopic disease, 40-50 Gy (2 Gy/day), adjusted to the bulk of disease; for microscopic disease, 36-40 Gy; after R0 surgery, no XRT is required, but close observation is needed. No attempts should be made to treat uninvolved nodal regions. Using Bartl's histologic grading criteria, trends were detected in patients with higher tumor grades: regional lymph node involvement (p = 0.04) and shorter disease-specific survival (p = 0.08). Extramedullary plasmacytoma is a highly curable disease when XRT is

The incidence of SDH in infants is between 12 and 25 cases per 100 000 children and most detected SDH are due to physical abuse. In the infant brain, SDH are caused by tearing of the bridging veins in the subdural space and may result in significant brain injury.

    Pediatric patients bridged to heart transplant with LVADs require chronic anticoagulation and are at increased risk of hemorrhagic complications, including intracranial hemorrhage. In this population, intracranial hemorrhage is often fatal. We report a case of successful management of a five-yr-old-boy with DCM on an LVAD who developed a subdural hematoma. We initially chose medical management, weighing the patient's high risk of thromboembolism from anticoagulation reversal against the risk of his chronic subdural hematoma. When head CT showed expansion of the hemorrhage with increasing midline shift, we chose prompt surgical evacuation of the hematoma with partial reversal of anticoagulation, given the increased risk of acute deterioration. The patient ultimately received an orthotopic heart transplant and was discharged with no permanent neurological complications. This represents a case of a pediatric patient on an LVAD who survived a potentially fatal subdural hematoma and was successfully bridged to cardiac transplantation. © 2012 John Wiley & Sons A/S.

    Retinal hemorrhage is a well-recognized manifestation of child abuse found in many babies with shaken baby syndrome. The presence of retinal hemorrhage is generally associated with more severe neurological damage and a worse clinical outcome. MR imaging findings of retinal hemorrhages are not well described in the pediatric literature. We present a 6-month-old boy with new-onset seizures, subdural hemorrhage and bilateral retinal hemorrhages that were detected by MRI and confirmed by indirect ophthalmoscopy. This case demonstrates the MR imaging findings of retinal hemorrhages and the importance of radiologists being able to recognize these specific imaging features. (orig.)

    Full Text Available Cerebellar hemorrhage following a spinal surgery is extremely rare; however, considering the localization, it can cause major clinical manifestations. While it is considered that these types of bleedings occur secondary to a venous infarct, the pathogenesis is still unclear. A 57-year-old male patient who underwent a laminectomy by exposing T12-L5 and had pedicle screws placed for ankylosing spondylitis developed a CSF leak due to a 2 mm dural tear. A hemorrhage with parallel streaks on the left cerebellar hemisphere was seen in CT scan, and a thin subdural hematoma at right frontotemporal region was seen on cranial MRI, performed after the patient developed intense headache, nausea, vomiting, and stiff neck in the early postoperative period. In this paper, a case of cerebellar and subdural hematomas following a spinal surgery is discussed with its clinical and radiologic findings.

    Spontaneous spinal subdural hematomas are rare. Their occurrence in a child with congenital von Willebrand disease and the complication of their surgery by a large secondary syringomyelia have never been previously reported. A 13-year-old girl with congenital von Willebrand disease presented to our emergency department in January 2011 for sudden onset of severe back pain centered in her thoracic spine rapidly aggravated by signs of acute myelopathy without any precipitating factor. MRI scan revealed a thoracic subdural collection anterior to the spinal cord at the T7-T9 level, hyperintense on T1- and T2-weighted sequences consistent with an acute spinal subdural hemorrhage. Evacuation of the subdural hematoma was realized immediately after hemostasis parameter correction, and post-operative course was uneventful with full functional recovery. One year later, the patient presented once again but with progressive and more severe myelopathy caused by a large syringomyelia extending from the T5 level to the conus medullaris. A syringopleural shunting was performed and the patient was unrolled under an intensive care and rehabilitation program. Her condition remarkably improved and she became able to walk independently within 2 weeks post-operatively. von Willebrand disease should be included as a possible factor of spontaneous spinal subdural hemorrhage. Surgery is advised in emergency and can be associated with remarkable recovery especially in children. Delayed syringomyelia can complicate the post-operative course and can be successfully addressed by syringopleural shunting. Long-term clinical and radiological follow-up is advocated.

    Full Text Available Cerebral amyloid angiopathy (CAA usually manifests as cerebral hemorrhage, especially as nontraumatic hemorrhages in normotensive elderly patients. Other manifestations are subarachnoid (SAH, subdural, intraventricular hemorrhage (IVH and superficial hemosiderosis. A 52-year-old hypertensive woman presented with recurrent neurological deficits over a period of 2 years. Her serial brain magnetic resonance imaging and computed tomography scans showed recurrent SAH hemorrhage, and also intracerebral, IVH and spinal hemorrhage, with superficial siderosis. Cerebral angiograms were normal. Right frontal lobe biopsy showed features of CAA. CAA can present with unexplained recurrent SAH hemorrhage, and may be the initial and prominent finding in the course of disease in addition to superficial cortical siderosis and intracerebal and spinal hemorrhages.

    Terson syndrome was originally used to describe a vitreous hemorrhage arising from aneurysmal subrarachnoid hemorrhage. Terson syndrome can be caused by intracranial hemorrhage, subdural or epidural hematoma and severe brain injury but is extremely rare in intraventricular hemorrhage associated with moyamoya disease. A 41-year-old man presented with left visual disturbance. He had a history of intraventicular hemorrhage associated with moyamoya disease three months prior to admission. At that time he was in comatose mentality. Ophthalmologic examination at our hospital detected a vitreous hemorrhage in his left eye, with right eye remaining normal. Vitrectomy with epiretinal membrane removal was performed. After operation his left visual acuity was recovered. Careful ophthalmologic examination is mandatory in patients with hemorrhagic moyamoya disease.

    Full Text Available Secondary parkinsonism is attributable to a wide variety of causes including supratentorial mass lesions. While tumors are known to present with parkinsonism, chronic subdural hematoma is rarely seen presenting as rapidly deteriorating parkinsonian features with complete disappearance following evacuation of hematoma. The authors present two such patients-70- and 78-year-old males who presented with sudden onset of parkinsonism features. Both failed to recollect any significant head injury. Imaging diagnosed the presence of chronic subdural hematomas, being unilateral in one and bilateral in other. Surgical evacuation resulted in complete resolution of parkinsonian symptoms. These cases reinforce earlier studies for chronic subdural hematoma to be one of the causes of reversible parkinsonism apparently from distortion of basal ganglia mechanically and bringing changes in dopaminergic function, harming the susceptible aging brain.

    Full Text Available Treatment of subdural cronic hematoma in all ages is a therapeutic challenge. Chronic subdural hematoma is a disease that can be fatal without surgical treatment. A variety of treatment options like subdural tapping, endoscopic washout, shunting and craniotomy have been discussed. In chronic subdural hematoma, spontaneous resolution with conservative treatment is not an common therapeutic method because it has causes high mortality, requires long periods of time, and finally, many patients need surgical treatment. The etiology, physiopathology and surgical alternatives in the treatment of subdural chronic hematoma is discussed.

  5. An unusual presentation of subdural empyema caused by Porphyromonas gingivalis

    2013-01-01

    Full Text Available Subdural empyema is an uncommon clinical entity. The first case of Porphyromonas gingivalis subdural empyema is reported. We report a case of 34-year-old male who presented with subdural empyema and sinusitis. Through the utilization of polymerase chain reaction (PCR tests on subdural pus, we were able to confirm the diagnosis and institute appropriate treatment. Early surgical intervention and intravenous antibiotics meant that the patient recovered fully. Infections caused by P. gingivalis should be considered in differential diagnoses of central nervous system (CNS abscesses or subdural empyema especially in patients with precedent periodontal diseases and sinusitis.

    Ependymoma is a glial tumor that occurs in the central nervous system. The intradural extramedullary location of this neoplasm is very rare. The authors report a case of spinal intradural extramedullary ependymoma in a male and discuss its pathogenesis as well as its clinical, radiological, and therapeutical features. A 31-year-old man was admitted at the author's institution. The patient has had 1-year history of cervical pain, progressive quadriplegia, and bladder disturbances. Magnetic resonance imaging revealed an enhanced cervical intradural extramedullary tumor extending from the bulbomedullary junction to the C3 level, with severe spinal cord compression. Emergency surgical resection was performed, and a total removal of the lesion was accomplished. One year and half later, a local recurrence associated to a small cerebellar lesion was noticed justifying a second spinal intervention. Both surgical interventions demonstrated an intradural extramedullary ependymoma without attachment to the spinal cord or to the dura mater. Adjuvant craniospinal radiotherapy was recommended to the patient. The insufficiency of hormonal theory to explain solely the pathogenesis of this tumor might reveal other potential factors that have not been discussed in earlier literature.

  12. Risk of Ischemic Stroke after Intracranial Hemorrhage in Patients with Atrial Fibrillation.

    Directory of Open Access Journals (Sweden)

    Michael P Lerario

    Full Text Available We aimed to estimate the risk of ischemic stroke after intracranial hemorrhage in patients with atrial fibrillation.Using discharge data from all nonfederal acute care hospitals and emergency departments in California, Florida, and New York from 2005 to 2012, we identified patients at the time of a first-recorded encounter with a diagnosis of atrial fibrillation. Ischemic stroke and intracranial hemorrhage were identified using validated diagnosis codes. Kaplan-Meier survival statistics and Cox proportional hazard analyses were used to evaluate cumulative rates of ischemic stroke and the relationship between incident intracranial hemorrhage and subsequent stroke.Among 2,084,735 patients with atrial fibrillation, 50,468 (2.4% developed intracranial hemorrhage and 89,594 (4.3% developed ischemic stroke during a mean follow-up period of 3.2 years. The 1-year cumulative rate of stroke was 8.1% (95% CI, 7.5-8.7% after intracerebral hemorrhage, 3.9% (95% CI, 3.5-4.3% after subdural hemorrhage, and 2.0% (95% CI, 2.0-2.1% in those without intracranial hemorrhage. After adjustment for the CHA2DS2-VASc score, stroke risk was elevated after both intracerebral hemorrhage (hazard ratio [HR], 2.8; 95% CI, 2.6-2.9 and subdural hemorrhage (HR, 1.6; 95% CI, 1.5-1.7. Cumulative 1-year rates of stroke ranged from 0.9% in those with subdural hemorrhage and a CHA2DS2-VASc score of 0, to 33.3% in those with intracerebral hemorrhage and a CHA2DS2-VASc score of 9.In a large, heterogeneous cohort, patients with atrial fibrillation faced a substantially heightened risk of ischemic stroke after intracranial hemorrhage. The risk was most marked in those with intracerebral hemorrhage and high CHA2DS2-VASc scores.

  13. A case of atypical chronic subdural hematoma: a spontaneous rupture of dural lymphoma nodule.

    2014-02-01

    In forensic medicine, a chronic subdural hematoma (SDH) usually results from trauma, sometimes minimal for elderly people. The case reported here is a forensic medical description of an atypical chronic subdural hematoma. A woman aged of 40-year-old died following a coma. The autopsy and histological analyses revealed the hemorrhagic disintegration of a lymphoid nodule, a metastasis from generalized lymphoma. The combination of chronic symptomatic SDH and a tumor of the dura mater have been described, but are very rare. The possibility of trauma, even minimal, has never been excluded in these cases. In fact, the clinical picture of these patients suggested a significant movement of the brain within the cranial cavity due to the physiological decrease in brain volume. In the reported case, this particular process was excluded since the spontaneous hemorrhagic effusion produced by the meningeal lymphoid nodule was the cause of the chronic SDH. This pathophysiological explanation was possible because the entire brain and meninges were removed for histological analysis. Trauma, even minimal trauma, is not always involved in the formation of a chronic SDH. Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    Full Text Available Background Context. Up to date, only four cases of primary intradural extramedullary spinal cord melanoma (PIEM have been reported. No previous reports have described a case of PIEM located in the lower thoracic spine with long-term follow-up. Purpose. Demonstrating an unusual, extremely rare case of melanoma manifestation. Study Design. Case report. Methods. We report a case of a 57-year-old female suffering from increasing lower extremity pain, left-sided paresis, and paraesthesia due to spinal cord compression caused by PIEM in the lower thoracic spine. Results. Extensive investigation excluded other possible primary melanoma sites and metastases. For spinal cord decompression, the tumor at level T12 was resected, yet incompletely. Adjuvant radiotherapy was administered two weeks after surgery. The patient was recurrence-free at 104 weeks after radiotherapy but presents with unchanged neurological symptoms. Conclusion. Primary intradural extramedullary melanoma (PIEM is extremely rare and its clinical course is unpredictable.

    Full Text Available We herewith report a case of extramedullary myeloid cell tumour presenting as leukaemia cutis for its rarity. It occurred in a 50 year old male patient who presented to us with a 40 days history of painless raised solid skin swellings over the trunk. Histopathological examination of the skin biopsy and bone marrow biopsy showed features suggestive of non-Hodgkin’s lymphoma. Immunophenotyping on skin biopsy specimens and bone marrow biopsy found tumour cells expressing CD43 and Tdt but were negative for CD3 and CD20. These features were consistent with extramedullary myeloid cell tumour involving skin and subcutis (cutaneous manifestation of acute myeloid leukaemia.

    The category of extramedullary intradural tumors includes a variety of lesions ranging from meningiomas originating from meningeal cells and nerve sheath tumors (neurofibromas, schwannomas) to less common primary tumors, such as lipomas, ependymomas, hemangiopericytomas, epidermoid cysts and dermoid cysts. Extramedullary metastases can occur as transcoelomic metastases in tumors of the central nervous system (CNS) or metastasization from other tumors. Magnetic resonance imaging (MRI) is the method of choice for localization and characterization of these lesions before treatment. (orig.) [German] Die Kategorie der extramedullaeren intraduralen Tumoren enthaelt Laesionen, die von den Nervenhuellen (Schwannome und Neurofibrome) oder von den meningealen Zellen ausgehen (Meningeome). Ependymome, Lipome, Haemangioperizytome, Epidermoidzysten und Dermoidzysten entsprechen selteneren primaeren Tumoren. Extramedullaere Metastasen koennen als Abtropfmetastasen bei ZNS-Tumoren oder als Metastasierung anderer Karzinomerkrankungen auftreten. Die Magnetresonanztomographie (MRT) ist die Methode der Wahl zur Abklaerung einer intraduralen Raumforderung. (orig.)

    Full Text Available Thalassemia is a hematologic disorder that causes ineffective hematopoiesis and is related to severe anemia, iron overload, extramedullary hematopoiesis, and hepatomegaly. Hepatomegaly is related to significant extramedullary hematopoiesis. The other sites that are involved in extramedullary hematopoiesis are spleen, lymph nodes, paraspinal regions, kidney, pleura, and intestine, but intracranial involvement is a rare presentation. We discuss about a case with intracranial medullary hematopoiesis in a thalassemic patient.

    The main skeletal abnormalities in ..beta..-thalassemia are widening of medullary spaces, rarefaction of bone trabeculae, thinning of cortical bone, and perpendicular periosteal spiculation. Premature epiphyseal fusion (PEF) and extramedullary hematopoiesis (EH) are found, though more rarely. The incidence of PEF and EH in 64 patients affected by ..beta..-thalassemia is reported. The different incidence of such complications in thalassemia major and intermedia is reported, and a possible correlation with transfusion regimen is also considered.

    Full Text Available Acute spontaneous subdural hematoma in a patient of multiple myeloma receiving chemotherapy is an unknown event, needing an urgent neurosurgical management. We report this patient who presented with progressive neurological deterioration and a low platelet count. She was successfully managed by craniotomy and evacuation of subdural hematoma with intraoperative transfusion of platelets. The acute spontaneous subdural hematoma in her was probably related to the bleeding diathesis due to thrombocytopenia associated with chemotherapy.

    Multiple myeloma is a plasma cell tumor that homes to and expands in the bone marrow and that, despite the new available drugs, remains incurable. Extramedullary plasmacytoma is a not frequent manifestation during the natural history of multiple myeloma and is frequently associated with plasma cell bone marrow infiltration. The most common locations for an EMP include the gastrointestinal tract, pleura, testis, skin, peritoneum, liver, endocrine glands, and lymph nodes. Primary involvement of the gallbladder fossa is exceedingly rare. In this report, we describe a patient with multiple myeloma who achieved a clinical and serological remission after autologous transplant but progressed rapidly at extramedullary site mimicking a second cancer (i.e., pancreatic or biliary cancer). In this case, the extramedullary localization was refractory to standard therapy, differently from bone marrow localization, but responded to lymphoma-like therapy. In this patient (i) the particular site of developing plasmacytoma is the gallbladder fossa, (ii) the timing of onset of this neoplasm is immediately after autologous transplant, and (iii) its disjunction from primary myeloma is that it appears in clinical and serological remission phase which may be confounding during the diagnostic approach simulating a different tumor (solid tumor).

    Extramedullary blast crisis of chronic myelogenous leukemia (CML) is defined as the development of extramedullary disease caused by the infiltration of blasts regardless of proliferation of blasts in the bone marrow. The onset of extramedullary blast crisis in the newly diagnosed patients is known to be extremely rare. Here, we present a case of extramedullary blast crisis of CML as an initial presentation in a 17-year-old female presenting with pain in the left femur tumor. This case was treated successfully with dasatinib and allogeneic hematopoietic stem cell transplantation, with achievement of long-term remission. PMID:24371785

    We highlight the orbital manifestations of acute myeloid leukemia and the role of peripheral blood smear in the diagnosis of these cases. A total of 12 patients who presented with proptosis and were subsequently diagnosed to have acute myeloid leukemia based on incision biopsy or peripheral blood smear were included in the study. A retrospective review of all cases of acute myeloid leukemia presenting to the Orbital clinic was performed. The age at presentation, gender, presenting features, duration of symptoms and fundus features were noted. In addition the temporal relationship of the orbital disease to the diagnosis of leukemia, laterality, location of the orbital mass, imaging features and the diagnostic tools used to diagnose leukemia were noted. The median age at presentation was 6 years. The male: female ratio was 0.7:1. None of these patients had been diagnosed earlier as having acute myeloid leukemia. The presenting features included proptosis in all patients, orbital mass in 5 (41.7%), visual symptoms in 2 (16.7%) and subconjunctival hemorrhage in one patient (8.3%). A diagnosis of acute myeloid leukemia was established by incision biopsy in 4 patients, subsequently confirmed by peripheral blood smear testing and bone marrow biopsy in 2 patients which revealed the presence of systemic involvement. Imprint smears of the biopsy identified blasts in 2 of 4 cases. In 8 patients presenting with ocular manifestations, diagnosis was established by peripheral blood smear examination alone which revealed a diagnosis of acute myeloid leukemia. A peripheral blood smear should be performed in all cases of sudden onset proptosis or an orbital mass in children and young adults along with an orbital biopsy. It can always be complemented with a bone marrow biopsy especially in cases of aleukemic leukemia or when the blood smear is inconclusive.

    Nermin Görkem Sirin

    2010-05-01

    Full Text Available Spinal subdural hematoma (SDH is a rare condition and can be caused by several factors. Concomitant cranial and spinal SDH is even much less common. We present a 77-year-old male patient with lower back pain, paraparesis, and urinary retention following a sudden onset headache. Imaging revealed concomitant cranial and spinal SDH related to cerebral venous thrombosis (CVT associated with hemorrhagic venous infarct. Laboratory examinations were consistent with polycythemia vera. There was no history of trauma and previous cranial surgery. Brain angiography did not reveal any evidence of arteriovenous fistula or vascular malformation. Since lower back pain occurred shortly after the headache and there was no other reasonable explanation for spinal hemorrhage, we suppose that the mechanism of spinal SDH is the migration of blood from the intracranial compartment. Therefore, this is the first report of concomitant spinal SDH and cerebral hemorrhage associated with CVT in a patient with myeloproliferative disease.

    Full Text Available The Shaken Baby Syndrome (SBS is characterized by subdural hematomas (SH, retinal hemorrhages (RH, and multiple fractures of long bones without external evidence of head trauma. Subinternal limiting membrane (ILM hemorrhage, also known as macular schisis, is a characteristic finding of this entity. There is no guideline on the right time to indicate surgical treatment. This report describes an abused child with massive sub-ILM hemorrhage, which showed spontaneous absorption after less than two months of follow-up. Due to the possible spontaneous resolution, we suggest an initial conservative treatment in cases of sub-ILM hemorrhage related to SBS.

    Full Text Available Arachnoid cysts (AC are extra-cerebral cerebrospinal fluid collections of unknown origin. They correspond to 1% of all intracranial nontraumatic space-occupying lesions and appear more frequently in the middle fossa (50%. More than 25% of these cysts are incidental findings and the majority of patients are asymptomatic. Seizures, intracranial hypertension signs, neurological deficits, macrocrania, developmental delay and bulging of the skull are the main signs and symptoms of the lesion. AC rupture and bleeding are rare, usually occurring in young adults and associated with trauma. The risk of hemorrhage does not exceed 0.04% / year. We describe the case of a ten-year-old boy who presented with acute signs of intracranial hypertension secondary to a spontaneous acute subdural hematoma, contralateral to an AC of the middle fossa. Three factors were significant in this case: signs and symptoms occurred spontaneously; the presence of an acute subdural hematoma exclusively contralateral to the AC; successful outcome of the conservative treatment.Os cistos aracnóideos (CA são coleções liquóricas extra-cerebrais e intra-aracnóideas de origem desconhecida. Correspondem a 1% de todas as lesões expansivas intracranianas não traumáticas e têm nítido predomínio na fossa média (50%. Até 25% destes cistos são achados incidentais sendo que a maioria dos pacientes é assintomática. Crises epilépticas, sinais de hipertensão intracraniana, déficits neurológicos focais, macrocrania, atraso no desenvolvimento e abaulamento da calota craniana são os principais sinais e sintomas da lesão. A ruptura dos CA, assim como seu sangramento, são situações raras, geralmente associadas a traumas e acometem adultos jovens. O risco de hemorragia em pacientes com CA não excede 0,04% ao ano.

    "Headbanging" is the slang term used to denote violent shaking of one's head in time with the music. This abrupt flexion-extension movement of the head to rock music extremely rarely causes a subdural hematoma. A 24-year-old female was admitted to our department because of right sided partial seizure and acute or subacute subdural hematoma over the left cerebral convexity. She had no history of recent head trauma but performed headbanging at a punk rock concert at 3 days before admission. Since, she had a previous acute subdural hematoma on the same side after an accidental fall from a baby buggy when she was 11 months old, the present was recurrent subdural hematoma probably due to headbanging. Headbanging has the hazardous potential to cause a subdural hematoma.

    Heyde syndrome is known as a triad of calcific aortic stenosis, anemia due to gastrointestinal bleeding from angiodysplasia, and acquired type 2A von Willebrand disease. This acquired hemorrhagic disorder is characterized by the loss of the large von Willebrand factor multimers due to the shear stress across the diseased aortic valve. The most frequently observed type of bleeding in these patients is mucosal or skin bleeding, such as epistaxis, followed by gastrointestinal bleeding. On the other hand, intracranial hemorrhage complicating Heyde syndrome is extremely rare. A 77-year-old woman presented to our hospital with severe aortic stenosis and severe anemia due to gastrointestinal bleeding and was diagnosed with Heyde syndrome. Although aortic valve replacement was performed without recurrent gastrointestinal bleeding, postoperative life-threatening acute subdural hematoma occurred with a marked midline shift. Despite prompt surgical evacuation of the hematoma, she did not recover consciousness and she died 1 month after the operation. Postoperative subdural hematoma is rare, but it should be kept in mind as a devastating hemorrhagic complication, especially in patients with Heyde syndrome.

  19. Triple manifestation of extramedullary plasmacytoma in the upper airway: an unusual clinical entity.

    OBJECTIVE: We report an extremely rare case of extramedullary plasmacytoma. METHOD: Case report and review of the English-literature concerning extramedullary plasmacytoma and multiple myeloma. RESULT: We present an unusual case of multiple extramedullary plasmacytomas, which, over a protracted course of 30 years, presented on different occasions at three separate sites in the head and neck. The patient was managed surgically on all occasions, and was disease-free at the time of writing. CONCLUSION: Following review of the literature, we believe this to be the only case with this extremely unusual presentation. This case is noteworthy, not only because of the rarity of extramedullary plasmacytoma, but also because it highlights a number of important clinical issues. The diagnosis and management of extramedullary plasmacytoma require close cooperation between multiple disciplines.

    An 8-year-old spayed female cross-breed dog was evaluated following a 2-month history of thoracic limb weakness. Neurological examination revealed a spinal cord lesion between C1 and C5 segments. Magnetic resonance imaging (MRI) revealed that almost 70% of the spinal canal between C1 and C2 was occupied by an intradural extramedullary mass that was connected to a paraspinal mass from the cranial aspect of C2 to the cranial aspect of C3. The dog was anaesthetised and a dorsal, right-sided hemilaminectomy was performed. A durotomy was performed to expose a multilobular mass located principally along the right dorsal-lateral aspect of the spinal cord. The mass did not appear to infiltrate the cord parenchyma. The abnormal tissue was removed as completely as possible using gentle dissection and submitted for histological evaluation. The histological findings were consistent with an intradural-extramedullary haemangioblastoma with paraspinal extension. Following surgery, no neurological deterioration was detected. A metronomic-dosing chemotherapy protocol was administered to prevent progression or recurrence of the tumour. Follow-up MRI studies were performed 3, 6 and 12 months after the surgery, confirming complete tumour removal and the absence of recurrence. Haemangioblastoma is an extremely rare neoplasm in animals and only two cases of this tumour have been reported, but in other anatomical locations. Haemangioblastomas in human patients are more commonly located in the cerebellum and intradural-extramedullary growth is extremely rare. The dog in this study responded favourably to combined surgery and metronomic chemotherapy and was clinically normal 1 year after surgery. © 2015 Australian Veterinary Association.

    Symptomatic chronic subdural hematoma (scSDH) is one of the most frequent diseases in neurosurgical practice, and its incidence is increasing. However, treatment modalities are still controversial. The aim of this retrospective single-center study is to compare for the first time two surgical methods in the treatment of subdural hematoma that have been proven to be efficient in previous studies in a direct comparison. We analyzed the data of 143 scSDHs in 113 patients undergoing surgery for subdural hematoma with placement of subperiosteal or subdural drainage after double burr-hole trepanation for hematoma evacuation. Overall, there were no statistically significant differences regarding general patient characteristics, preoperative and postoperative symptoms, postoperative hematoma remnant, rates of recurrences, mortality, complications, and outcome at discharge and at 3-month follow up between the groups. There was a close to significant tendency of lower mortality after placement of subperiosteal drainage system and a tendency towards lower rate of recurrent hematoma after placement of subdural drainage system. Our study shows for the first time a direct comparison of two mainly used surgical techniques in the treatment of scSDH. Both methods proved to be highly effective, and general patient data, complications, outcome and mortality of both groups are equal or superior compared with previously published series. Because there is a clear tendency to less mortality and fewer serious complications, treatment with double burr-hole trepanation, irrigation, and placement of subperiosteal drainage is our treatment of choice in patients with predictable high risk of complications.

    Subdural-peritoneal (SP) shunting is a simple procedure to treat subdural hygromas; however, several rare complications such as shunt migration exist. A 15-year-old boy presented with headache, nausea, and vomiting, and underwent SP shunting for left frontoparietal chronic subdural effusion. Six weeks later, radiographic examinations revealed total migration of the shunt through the pelvic inlet. The migrated shunt was replaced with a new SP shunt. Four weeks later, radiographic examinations revealed shunt migration into the subdural space. The shunt catheter was removed and the subdural effusion was evacuated. Shunt migration may result from pressure differences between the abdomen and the cranium or from head movement, and insufficient fixation and/or large burr holes can facilitate shunt migration. Double firm anchoring and small-sized burr holes can prevent this complication. SP shunt is a simple procedure, and its assumed complications can be prevented through precaution.

    Full Text Available Solitary plasmacytoma (SP is an extremely rare form of hematologic malignancy that can be classified as solitary bone plasmacytoma or solitary extramedullary plasmacytoma. Here, we report a patient who presented with progressive shortness of breath and foreign body sensation in his throat. Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT demonstrated an abnormal FDG-avid soft tissue mass arising from the larynx involving the cricoid cartilage without additional suspicious lesions. Histology revealed an abundance of plasma cells; immunohistochemistry was positive for CD138 expression and lambda chains, and negative for CD20. Comprehensive imaging studies and panendoscopy of the ENT tract confirmed solitary disease involvement. Following additional systemic work-up, a diagnosis of extramedullary plasmacytoma was rendered. The patient underwent definitive radiotherapy using intensity-modulated radiation therapy (total dose of 46 Gy, divided in 23 fractions of 200 cGy. Serial PET/CT showed the stepwise resolution of abnormal FDG uptake and resolution of the cricoid cartilage lesion. With 22 months of follow-up, the patient remains free of disease. We describe the rare case of SP presenting as a FDG-avid hypermetabolic soft tissue mass in the cricoid cartilage, which should be considered in the differential diagnosis of laryngeal tumors. Of note, SP is radiosensitive; favorable outcome can be expected once treated with doses of 40–50 Gy. FDG PET/CT is helpful in diagnosis and response assessment for this disease.

    Full Text Available Victoria Cui,1 Timur Kouliev2 1Washington University School of Medicine, St Louis, MO, USA; 2Emergency Department, Beijing United Family Hospital, Beijing, China Abstract: Acute subdural hematoma (SDH resulting from head trauma is a potentially life-threatening condition that requires expedient diagnosis and intervention to ensure optimal patient outcomes. Rapidly expanding or large hematomas, elevated intracranial pressure, and associated complications of brain herniation are associated with high mortality rates and poor recovery of neurological function. However, smaller bleeds (clot thickness <10 mm or hematomas occurring in infrequent locations, such as the tentorium cerebelli, may be difficult to recognize and patients may present with unusual or subtle signs and symptoms, including isolated cranial nerve palsies. Knowledge of neuroanatomy supported by modern neuroimaging can greatly aid in recognition and diagnosis of such lesions. In this report, we present a case of isolated oculomotor nerve palsy resulting from compressive tentorial SDH following blunt head trauma, review the literature concerning similar cases, and make recommendations regarding the diagnosis of SDH in patients presenting with isolated cranial nerve palsies.

    Full Text Available A 49-year-old man with end-stage renal disease was admitted to the hospital with a severe headache and vomiting. On neurological examination the Glasgow Coma Scale (GCS score was 15 and his brain CT showed acute subdural hematoma over the right cerebral convexity with approximately 11-mm thickness and 9-mm midline shift. We chose a conservative treatment of scheduled neurological examination, anticonvulsant medication, serial brain CT scanning, and scheduled hemodialysis (three times per week without using heparin. Ten days after admission, he complained of severe headache and a brain CT showed an increased amount of hemorrhage and midline shift. Emergency burr hole trephination and removal of the hematoma were performed, after which symptoms improved. However, nine days after the operation a sudden onset of general tonic-clonic seizure developed and a brain CT demonstrated an increased amount of subdural hematoma. Under the impression of persistent increased intracranial pressure, the patient was transferred to the intensive care unit (ICU in order to control intracranial pressure. Management at the ICU consisted of regular intravenous mannitol infusion assisted with continuous renal replacement therapy. He stayed in the ICU for four days. Twenty days after the operation he was discharged without specific neurological deficits.

    Full Text Available Conservative management of subdural haematoma with antioedema measures in second gravida with idiopathic thrombocytopenic purpura (ITP resulted in resolution of haematoma. We present a case of second gravida with ITP who developed subdural haematoma following normal vaginal delivery. She was put on mechanical ventilation and managed conservatively with platelet transfusion, Mannitol 1g/kg, Dexamethasone 1mg/kg and Glycerol 10ml TDS. She regained consciousness and was extubated after 48 hrs. Repeat CT after 10 days showed no mass effect with resolving haematoma which resolved completely after 15 days. Trial of conservative management is safe in pregnant patient with ITP who develops subdural haematoma.

    2017-02-01

    Full Text Available Background: Chronic subdural hematomas (CSDH tend to occur most commonly in the elderly population, usually resulting from minor or insignificant head trauma. The pathophysiology behind CSDH is often directly associated with cerebral atrophy, and other causes of cerebral atrophy such as alcoholism or dementia. Other predisposing factors include diabetes, coagulopathy, use of anticoagulants (including aspirin, seizure disorders, and CSF shunts. Considerable evidence supporting the use of external drainage after evacuation of primary CSDH is readily available in the literature. Case report: We report the case of a 72 year-old male with a history of recurrent left subdural hematoma presenting to the neurosurgical clinic with a two-day history of personality changes, difficulty speaking, urinary incontinence, and headaches. Burr hole evacuation was performed with the placement of a subdural peritoneal shunt. At the one-month follow-up appointment, the patient had complete resolution of symptoms and CT scan showed no new recurrence of the subdural hematoma. Conclusions: Although several treatment options are available for the management of CSDH, recurrence of hematoma is a major and very common complication that may result in re-injury due to mass effect caused by chronic hematoma. However, placement of subdural peritoneal shunt for the treatment of CSDH can reduce the recurrence rate of CSDH and therefore, reduce the risk of brain re-injury.

    Multiple myeloma is a common hematological malignancy. Aggressive myeloma invades the organs outside the bone marrow, lymph, or reticuloendothelial systems. Among the extramedullary involvements of multiple myeloma, myelomatous ascites are extremely rare and are associated with a poor prognosis. We describe a case of myelomatous ascites as an initial manifestation of extramedullary involvement of multiple myeloma in 39-year-old patient. The patient was treated with high-dose chemotherapy, but extensive extramedullary involvement progressed, and the patient expired approximately five months after the initial detection of ascites.

    Spectrophotometric examinations were performed on cerebrospinal and subdural fluids in subacute (five patients) and chronic (20 patients) subdural haematomas, with special reference to the diagnostic aid of CSF spectrophotometry. Spectrophotometric xanthochromia of haemorrhagic origin was found in all CSFs examined, while definite visible xanthochromia was observed in only 28% and the CSF was judged as colourless in 52% of those cases. Characteristic bleeding patterns were found spectrophotometrically in all the 20 CSFs examined within 24 hours after lumbar puncture, haematoma patterns being detected in 90-95% of the cases. In many cases the electrophoretically separated protein fractions of CSF and subdural fluids were spectrophotometrically examined. In conclusion, CSF spectrophotometry is a simple, fast, and extremely sensitive method, which in our opinion should be used routinely in the diagnosis of suspected subdural haematomas, if lumbar puncture is not contraindicated.

    Extramedullary plasmacytomas are plasma cell tumors that arise outside of the bone marrow. They account for approximately 3% of plasma cell neoplasms and are most frequently located in the head and neck region. Five months after undergoing cholecystectomy, a 69-year-old patient presented with the pain under the right costal margin and a 12 kg weight loss. Computed tomography of the abdomen demonstrated irregular, vascular mass in the gallbladder fossa that dents towards the duodenum and the pylorus and lowers caudally to the hepatic flexure. His laboratory tests indicated normocytic anemia and showed elevated sedimentation rate. During operative procedure, a tumorous mass in the gallbladder fossa was found, inseparable of the peritoneum of the hepatoduodenal ligament and the IVb liver segment. Histopathological examination and immunohistochemical staining determined the diagnosis of the plasmacytoma. Total resection of the tumor was achieved and after 24-month follow-up patient showed no signs of local recurrence or dissemination of the disease.

    BACKGROUND: The prognostic significance of extramedullary leukemia (EML) in childhood acute myeloid leukemia is not clarified. PROCEDURE: This population-based study included 315 children from the NOPHO-AML 2004 trial. RESULTS: At diagnosis, 73 (23%) patients had EML: 39 (12%) had myeloid sarcoma......, 22 (7%) had central nervous system disease, and 12 (4%) had both. EML was associated with young age (median age: 2.6 years), a high white blood cell count (median: 40 × 109 /l), M5 morphology (40%), and 11q23/MLL (KMT2A) rearrangements (34%). No patient received involved field radiotherapy. Five......-year event-free survival did not differ significantly between the EML and the non-EML patients (54% vs. 45%, P = 0.57), whereas 5-year overall survival (OS) was significantly lower in the EML group (64% vs. 73%, P = 0.04). The risk of induction death was significantly higher for EML patients (8% vs. 1%, P...

    Spinal teratomas are extremely rare; they constitute meningitis. A 7-year-old boy presented with paroxysmal abdominal pain and a history of recurrent aseptic meningitis. Kernig and Brudzinski signs were present. Lumber puncture revealed pleocytosis with no evidence of bacteria growth. Imaging of the spine revealed a cystic lesion in spinal cord at thoracic level 9-11. Endoscopic excision of the cyst was successfully performed. Surgical and histopathological findings confirmed extramedullary matured teratoma. As the symptomatic attacks of spontaneous rupture of spinal teratoma resemble presentations of Mollaret meningitis, spinal teratoma should be considered in the differential diagnosis of Mollaret meningitis. We describe a rare example of spinal teratoma causing recurrent meningitis. Spine imaging should be considered in individuals with recurrent aseptic meningitis as this promotes earlier diagnosis, more appropriate treatment, and improved neurological outcome.

    Full Text Available Abstract Background In a standard total knee replacement, tibial component alignment is a key factor for the long term success of the surgery. The purpose of this study is to compare the accuracy of extramedullary and intramedullary tibial cutting guides used in indigenous and imported implants respectively, in positioning of the tibial components in megaprosthetic knee replacements. Methods A comparative study of the accuracy of extramedullary and intramedullary tibial cutting guides was carried out in 92 megaprosthetic knee replacements for distal femoral tumors. For the proximal tibia cut for tibial component placement, an extramedullary guide was used in 65 patients and an intramedullary guide was used in 27 patients. Tibial component alignment angles were measured in postoperative X-rays with the help of CAD software. Results There was more varus placement in coronal plane with extramedullary cutting guide (−1.18 +/− 2.4 degrees than the intramedullary guide (−0.34 +/− 2.31 degrees but this did not reach statistical significance. The goal of 90 +/− 2 degrees alignment of tibial component was achieved in 54% of patients in the extramedullary group versus 67% in the intramedullary group. In terms of sagittal plane alignment, extramedullary guide showed less accurate results (2.09 +/− 2.4 degrees than intramedullary guide (0.50 +/− 3.80 degrees for tibial component alignment, though 78% of patients were aligned within the goal of 0–5 degrees of tibial slope angle in extramedullary group versus 63% in intramedullary group. The mean error in the measurements due to rotation of the knee during taking the X-rays was less than 0.1 degrees and distribution of the X-rays with the rotation of knee was similar in both the groups. Conclusions Overall, in megaprosthetic knee replacement intramedullary guides gave more accurate results in sagittal plane and exhibited similar variability as of extramedullary guides in coronal plane.

    Extramedullary haematopoiesis is a physiological response to chronic anemia, observed frequently during homozygous thalassemia. It is usually asymptomatic but can be manifested by compression of adjacent organs, particularly the spinal cord. A 44-year-old woman diagnosed with thalassaemia intermedia, was admitted for difficulties to walk and sphincter disturbances. Neurologic examination suggested spinal cord compression, which is confirmed by dorso-lumbar resonance magnetic imaging. The histology obtained by laminectomy led to the diagnosis of extramedullary hematopoiesis related to thalassemia. A radiotherapy enabled with good outcome. Spinal cord compressions by extramedullary hematopoiesis during thalassemia are uncommon (75 cases in the literature) but can induce severe sequelae if the diagnostic is not rapidly obtained. Magnetic resonance imaging is the gold standard allowing precise diagnosis and spreading of extramedullary hematopoiesis. Radiotherapy and more recently hydroxyurea are the first line treatment. This observation recalls that extramedullary hematopoiesis is a differential diagnostic of spinal cord compression in patients with thalassemia. A screening of paravertebral localization of extramedullary hematopoiesis should be performed in high risk thalassemic patients.

    2012-01-01

    Full Text Available Background. Extramedullary hematopoiesis is most often seen in reticuloendothelial organs specially spleen, liver, or lymph nodes, and it is rarely seen in lung parenchyma. Almost all reported cases of pulmonary extramedullary hematopoiesis occurred following myeloproliferative disorders specially myelofibrosis. Other less common underlying causes are thalassemia syndromes and other hemoglobinopathies. There was not any reported case of pulmonary extramedullary hematopoiesis in asthmatic patients in the medical literature. Case. Here we reported a 65-year-old lady who was a known case of bronchial asthma with recent developed right lower lobe lung mass. Chest X-ray and CT studies showed an infiltrating mass resembling malignancy. Fine needle aspiration cytology of mass revealed pulmonary extramedullary hematopoiesis. The patient followed for 10 months with serial physical examination and laboratory evaluations which were unremarkable. Conclusion. Extramedullary hematopoiesis of lung parenchyma can be mistaken for lung cancer radiologically. Although previous reported cases occurred with myelofibrosis or hemoglobinopathies, we are reporting the first case of asthma-associated extramedullary hematopoiesis.

    Full Text Available Solitary plasmacytoma (SP is characterized by a mass of neoplastic monoclonal plasma cells in either bone (SBP or soft tissue without evidence of systemic disease attributing to myeloma. Biopsy confirmation of a monoclonal plasma cell infiltration from a single site is required for diagnosis. The common presentation of SBP is in the axial skeleton, whereas the extramedullary plasmacytoma (EMP is usually seen in the head and neck. The ratio of SP seen at males to females is 2 : 1 and the median age of patients is 55 years. The incidence rate of SP in black race is approximately 30% higher than the white race. Incidence rate increases exponentially by advancing age. SBP has a significant higher risk for progression to myeloma, and the choice of treatment is radiotherapy (RT that is applied with curative intent at min. 4000 cGy. By only RT application, long-term disease-free survival (DFS is possible for approximately 30% of patients with SBP and 65% of patients with EMP.

A 29-year-old nulliparous female presented with heavy vaginal bleeding and a hematocrit of 22%. No bone marrow biopsy has been performed. She had a history of uterine leiomyomata and menorrhagia for a year. A transvaginal ultrasound confirmed the presence of a uterine leiomyoma. The patient was treated conservatively with oral contraceptive pills due to desire for fertility. However, she continued to have heavy vaginal bleeding and developed bilateral upper extremity deep vein thrombosis and multiple superficial vein thromboses after two months. An exploratory laparotomy with uterine myomectomy was performed. Gross examination of the specimen revealed a single nodular mass measuring 10.0×9.5×7.5 cm with a white-tan swirling cut surface. Microscopic examination revealed benign smooth muscle consistent with leiomyoma and numerous intravascular thrombi both with areas of EMH. Immunohistochemical stains confirmed the presence of all three benign lineages of hematopoietic cells. Occurrence of EMH in uterine leiomyoma and intravascular thrombi is very rare. It may be related to systemic hematopoietic stimulation due to severe chronic anemia and local presence of hematopoietic growth factors and/or cytokines.

    Extramedullary plasmacytoma of the head and neck region (EMPHN) is an uncommon malignant plasma cell neoplasm. In this study we conducted a retrospective analysis of our experience of EMPHN with particular emphasis on the role of definitive radiotherapy. From 1982 to 2001, 10 patients (6 males, 4 females) with EMPHN were treated in our institution. Of nine patients treated at initial diagnosis, all received definitive radiotherapy. One patient treated at relapse underwent surgical resection followed by post-operative radiotherapy. The median age at diagnosis was 55 years (range 35-84 years). The disease was most frequently localized in the paranasal sinuses (50%). All nine patients who received definitive radiotherapy at a dose of 40-50 Gy achieved a complete response. The median follow up period was 29 months (range 7-67 months). Four patients (40%) relapsed, three have died of their disease. Two patients (20%) with paranasal sinus disease subsequently relapsed with multiple myeloma at 10 months and 24 months, respectively. Our results indicate that treatment of EMPHN with radiotherapy achieves excellent rates of local control. The relapse rate in neck nodes of 10% does not justify elective irradiation of the uninvolved neck.

Because chronic implantation of intracranial electrodes carries a risk of infection, hemorrhage, and edema, it is best to limit the number of electrodes used without compromising the ability to localize the epileptogenic zone (EZ. There is always a risk that an intracranial study may fail to identify the EZ because of suboptimal coverage. We present a new subdural electrode design that will allow better sampling of suspected areas of epileptogenicity with lower risk to patients. Method: Impedance of the proposed electrodes was characterized in vitro using electrochemical impedance spectroscopy. The appearance of the novel electrodes on magnetic resonance imaging (MRI was tested by placing the electrodes into a gel solution (0.9% NaCl with 14 g gelatin. In vivo neural recordings were performed in male Sprague Dawley rats. Performance comparisons were made using microelectrode recordings from rat cortex and subdural/depth recordings from epileptic patients. Histological examinations of rat brain after 3-week icEEG intracerebral electroencephalography (icEEG recordings were performed. Results: The in vitro results showed minimum impedances for optimum choice of pure gold materials for electrode contacts and wire. Different attributes of the new electrodes were identified on MRI.

    Infection of a subdural hematoma is an unusual cause of subdural empyema, with fewer than 50 cases reported in the literature. The appropriate surgical option for this entity has not been determined because of its rarity. We present a case report of a post-traumatic subdural hematoma infected with Escherichia coli that was successfully treated with craniotomy. In addition, we performed a PubMed search to comprehensively illustrate the causative organism, source of infection, clinical picture, surgical treatment, and outcome for this condition. This article presents an update on the condition. A 55-year-old man was admitted to our hospital complaining of headache, seizure, and urinary incontinence. He had a history of alcoholism and several hospitalizations for mild head trauma. Neuroimaging studies revealed a chronic hematic collection in the left frontal-parietal region. Laboratory tests showed increased C-reactive protein levels. In addition, surgical results revealed an infected subdural hematoma. A bacterial culture of the purulent specimen identified E. coli. In view of the urinary complaint and leukocyturia, the cause of the infected subdural hematoma was postulated as a urinary tract infection. Infected subdural hematoma is an unusual disorder. We must keep in mind the possibility of this complication when seeing a patient who presents with any of the 3 most common symptoms in this review. In these patients, craniotomy should be the method of surgical drainage, especially in adults. It ensures maximal drainage of the loculated pus and allows the total removal of the infected hematoma capsule. Copyright © 2016 Elsevier Inc. All rights reserved.

    Spontaneous chronic spinal subdural hematoma is rare. We describe a case of spontaneous chronic spinal subdural hematoma associated with arachnoiditis and syringomyelia in a 76-year old woman who presented with a 14-year history of progressive myelopathy. MRI scan revealed a thoraco-lumbar subdural cystic lesion and a thoracic syrinx. The patient underwent thoracic laminectomy and decompression of the lesion, which was a subdural hematoma. A myelotomy was performed to drain the syrinx. Pathological examination revealed features consistent with chronic subdural membrane. This report attempts to elucidate the pathogenesis of chronic spinal subdural hematoma. We discuss possible etiological factors in light of the current literature and pathogenesis of both spinal subdural hematoma and syrinx formation.

    For chronic subdural hematoma, placement of a Blake drain with a two-burr-hole craniotomy is often preferred. However, the placement of such drains carries the risk of penetrating the brain surface or damaging superficial venous structures. To describe the use of a Nelaton catheter for the placement of a subdural drain in two-burr-hole trephination for chronic subdural hematoma. A Nelaton catheter was used to guide placement of a Blake drain into the subdural hematoma cavity and provide irrigation of the hematoma cavity. With the two-burr-hole method, the Nelaton catheter could be removed easily via the frontal burr hole after the Blake drain was in place. We used the Nelaton catheters in many surgical procedures and found it a safe and easy technique. This method allows the surgeon to safely direct the catheter into the correct position in the subdural space. This tool has two advantages. First, the use of a small and flexible Nelaton catheter is a safe method for irrigation of a chronic subdural hematoma cavity. Second, in comparison with insertion of subdural drainage alone through a burr hole, the placement of the Nelaton catheter in subdural space is easier and the risk of damaging relevant structures such as cortical tissue or bridging veins is lower. Thus this technique may help to avoid complications when placing a subdural drain. Georg Thieme Verlag KG Stuttgart · New York.

    Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Relapse of ALL occurs in 15%-20% of patients, with 2%-6% occurring exclusively in extramedullary sites. Relapse of ALL in gynecologic organs is extremely rare. We present a case of a 12-year-old girl with a history of ALL who was referred to the pediatric gynecology clinic with abnormal uterine bleeding. She was determined to have an extramedullary uterine relapse of her ALL. Abnormal uterine bleeding in the setting of childhood malignancy is a frequent reason for consultation to pediatric and adolescent gynecology services. This bleeding is commonly attributed to thrombocytopenia due to bone marrow suppressive chemotherapeutic agents. However, as shown in this report, abnormal uterine bleeding might be a manifestation of an extramedullary relapse. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

    2008-04-01

    Most of the recent evidence suggests that extramedullary plasmacytoma should be treated initially with radiation, as response rates have exceeded 90% in many studies. Surgery is not considered a primary treatment modality for such tumors. We report the case of a chronically immunosuppressed 43-year-old man with bilateral extramedullary plasmacytomas of the nasal cavities. The right-sided mass was surgically excised, while the left-sided mass was initially treated with radiation. However, the left mass proved to be radioresistant, and it was subsequently excised surgically The patient showed no evidence of recurrence of either mass at 42 months of follow-up. We believe that the particulars of this case, combined with the results of some recent studies, provide good evidence that surgery should be considered in the treatment of certain cases of extramedullary plasmacytoma.

    Extramedullary plasmacytomas are localized tumours formed of monoclonal plasma cells in an extra-skeletal area. They constitute approximately 3% of all neoplasms originating from plasma cells. They generally display a destructive course. When the literature in English was reviewed, only 19 cases with the primary disease localized in the sphenoid sinus were found. We present the case of a 50-year-old male patient who presented with gradually increasing visual loss over 6 weeks, whose radiological tests revealed a formation of mass in the sphenoid sinus pressing against the optic nerve and internal carotid artery. A biopsy obtained by endoscopic sinus surgery was reported to be a plasmacytoma. A diagnosis of extramedullary plasmacytoma was made after investigations for other neoplastic plasma cell conditions proved negative. Extramedullary plasmacytomas were assessed by reviewing the literature. Copyright © 2012 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

    Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells. Most lesions occur in the head and neck, primarily in the upper aerodigestive tract. The nasal cavity and nasal septum are the most common sites of occurrence. In this report, three patients admitted in our clinic with history of nasal obstruction and/or epistaxis. Patients were diagnosed with extramedullary plasmacytoma and mass were completely excised. This entity usually occurred in 5th-6th decade of life. One of our patients, a young man, was completely asymptomatic and following a paroxysm of coughing, a polypoid mass was expectorated. The clinical and histopathologic findings of plasmacytoma are discussed. In order to exclude systemic involvement, systematic approach using clinical, laboratory, and radiologic investigations was performed. Extramedullary plasmacytoma of the nasal cavity is rare and should be considered in the differential diagnosis of nasal cavity masses especially in young age group. PMID:24083014

    Intracerebral Hemorrhage (IH) is an important cause of secondary brain injury in neurosurgical patients. Early identification and treatment improve neurologic outcome. We have tested Near Infrared Spectroscopy (NIRS) as an alternative noninvasive diagnostic tool compared to CT-Scans to detect IH. We prospectively studied 212 patients with neurologic symptoms associated with intracranial pathology before performing a CT-scan. NIRS signals indicated pathologies in 181 cases (sensitivity 0.96; specificity 0.29). In a subgroup of subdural hematomas NIRS detected 45 of 46 hematomas (sensitivity 0.96; specificity 0.79). Identification of intracerebral hemorrhage using NIRS has the potential to allow early treatment, thus possibly avoiding further injury.

    Subdural hematomas (SDHs) in full-term infants have the potential to cause death or lifelong disability. We report management and outcomes of eight cases of newborn with large SDH treated by streptokinase (SK) lavage and drainage. Between 2003 and 2006, eight infants with large acute SDH with focal or diffuse hypodensity showing signs and symptoms of neurological deterioration were treated by drainage and subdural SK lavage. There were eight full-term infants, five boys and three girls, with ages between 10 days and 2 months. Head injuries were shaken baby syndrome in three cases, fall from height in three cases, caused by traffic accident in one case, and reportedly not due to trauma in one case. In all patients, SDHs were unilateral. We used a new surgical approach, SDH evacuation, involving the subdural instillation of SK for lysis and after drainage of acute SDH in infants. Follow-up in the series ranged from 1 to 42 months (average 30 months). There was no mortality in this series, neither in the early postoperative period nor in the follow-up period. Five patients of this series lead a normal life; two children were mildly neurodevelopmentally delayed. Subdural infusion of SK followed by drainage may be as safe and effective for treatment of acute SDHs in infants as other reported methods.

    An 86-year-old woman was admitted to the intensive care unit with a chronic subdural hematoma (CSDH) and rapid onset of worsening neurological symptoms. She was taken to the operating room for a mini-craniotomy for evacuation of the CSDH including excision of the dura and CSDH membrane. Postoperatively, a subdural evacuation port system (SEPS) was integrated into the craniotomy site and left in place rather than a traditional subdural catheter drain to evacuate the subdural space postoperatively. The patient had a good recovery and improvement of symptoms after evacuation and remained clinically well after the SEPS was removed. We offer the technique of dura and CSDH membrane excision plus SEPS drain as an effective postoperative alternative to the standard craniotomy leaving the native dura intact with traditional subdural drain that overlies the cortical surface of the brain in treating patients with CSDH.

    65 newborns or low-birthweight infants with suspicion of intracranial hemorrhage were examined with B-mode small part scanners. In 12 cases the diagnosis made by ultrasound could be compared with CT. There was a similar accuracy of both methods in case of intraventricular (IVH) and subependymal (SEH) hemorrhage. SEH seems to be easier detected by US. On the other hand there are problems in diagnosing subdural (SDH) and intracerebral (IHC) hemorrhages by US. These problems are caused by the adjacent skull, but does not exist for CT. B-mode-Echoencephalography is the method of choice for examination of high risk infants and for the follow up, because US is a cribside method and of high diagnostic accuracy. CT-studies should be done in case of hemorrhage adjacent to the skull and if the US-diagnosis seems not to be reliable.

    Thromboembolic events and anticoagulation-associated bleeding events represent frequent complications following cardiac mechanical valve replacement. Management guidelines regarding the timing for resuming anticoagulation therapy following a surgically treated subdural hematoma (SDH) in patients with mechanical valves remains to be determined. To determine optimal anticoagulation management in patients with mechanical heart valves following treatment of SDH. Outcomes were retrospectively reviewed for 12 patients on anticoagulation therapy for thromboembolic prophylaxis for mechanical cardiac valves who underwent surgical intervention for a SDH at the Johns Hopkins Hospital between 1995 and 2010. The mean age at admission was 71 years. All patients had St. Jude's mechanical heart valves and were receiving anticoagulation therapy. All patients had their anticoagulation reversed with vitamin K and fresh frozen plasma and underwent surgical evacuation. Anticoagulation was withheld for a mean of 14 days upon admission and a mean of 9 days postoperatively. The average length of stay was 19 days. No deaths or thromboembolic events occurred during the hospitalization. Average follow-up time was 50 months, during which two patients had a recurrent SDH. No other associated morbidities occurred during follow-up. Interruptions in anticoagulation therapy for up to 3 weeks pose minimal thromboembolic risk in patients with mechanical heart valves. Close follow-up after discharge is highly recommended, as recurrent hemorrhages can occur several weeks after the resumption of anticoagulation.

    Summary Subdural haemorrhage from a ruptured intracranial aneurysm is a well-known entity when associated with subarachnoid haemorrhage. However, haemorrhage confined only to the subdural space is rare because there are limited anatomical sites where extravasation can be purely subdural. We report the rare case of a patient who suffered pure subdural haematoma after the rupture of a left superior hypophyseal artery aneurysm located within the sella turcica. The patient was treated with endovascular coil embolization of the aneurysm. Angiography immediately after treatment and one month later revealed complete obliteration of the aneurysm. Six months after treatment, the patient remained symptom free. PMID:20587264

    Full Text Available We report the case of a 25-year-old woman, who received epidural analgesia for labor pain and subsequently presented post-dural puncture headache. Conservative treatment was applied and epidural blood patch was performed. In the absence of clinical improvement and due to changes in the postural component of the headache, a brain imaging test was performed showing a bilateral subdural hematoma. The post-dural puncture headache is relatively common, but the lack of response to established medical treatment as well as the change in its characteristics and the presence of neurological deficit, should raise the suspicion of a subdural hematoma, which although is rare, can be lethal if not diagnosed and treated at the right time.

    To report one case of prostatic abscess and subdural empyema by Staphylococcus aureus. We describe the case of a 51 year old male patient who was diagnosed of prostatic abscess and subdural empyema by Staphilococcus aureus. We use clinical presentation and physical exploration based on rectal digital examination, as diagnostic approach method. And computerized axial tomography and transrectal ultrasonography, which allows the guided needle drainage of the abscess, as diagnostic confirmation methods. The clinical picture resolved with the transrectal ultrasonography guided needle aspiration of the abscess and conservative treatment with antibiotics and urinary diversion. Prostatic abscess is an uncommon entity nowadays. Provided the great variety of symptoms, a great degree of clinical suspicion is needed for the diagnosis, and once it is got it, immediate aggressive treatment must be initiated. Transrectal ultrasonography allows not only the diagnosis, but also the drainage of the abscess. The culture of the obtained material identifies the etiological agent and the most specific antibiotic therapy.

    Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [German] Spinale subdurale Haematome sind im Vergleich zu epiduralen Haematomen selten, chronische Verlaufsformen noch seltener. Ursaechlich sind neben Lumbalpunktionen und traumatischen Verletzungen auch Blutgerinnungsstoerungen, Gefaessmalformationen und Tumoren. Aufgrund der Kompression von Myelon und Cauda equina kommt es zu zunehmenden Ruecken- oder radikulaeren Schmerzen mit anschliessender Paraparese sowie einer Darm- und Blasenstoerung, weshalb in den meisten Faellen eine operative Entlastung durchgefuehrt wird. Magnetresonanztomographisch stellen sich die Haematome meist als thorakale bzw. lumbale subdurale Raumforderungen dar, die Signalintensitaet variiert mit dem Blutungsalter. Wir berichten ueber den klinischen Verlauf und die bildgebende Diagnostik von 3 Patienten mit spinalen chronischen subduralen Haematomen. (orig.)

    This retrospective comparative cohort study was aimed at discovering the risk factors associated with subdural hygroma (SDG) following decompressive craniectomy (DC) to relieve intracranial hypertension in severe head injury. Sixty-eight of 104 patients who had undergone DC during a 48-month period and survived > 30 days were eligible for this study. To assess the dynamics of subdural fluid collections, the authors compared CT scanning data from and the characteristics of 39 patients who had SDGs with the data in 29 patients who did not have hygromas. Variables significant in the appearance, evolution, and resolution of this complication were analyzed in a 36-week longitudinal study. The earliest imaging evidence of SDG was seen during the 1st week after DC. The SDG volume peaked between Weeks 3 and 4 post-DC and was gradually resolved by the 17th week. Among the mechanisms of injury, motor vehicle accidents were most often linked to the development of an SDG after DC (p SDGs were ipsilateral to the side of the craniectomy, and 3 (8%) of 39 SDGs showed evidence of internal bleeding at approximately 8 weeks postinjury. Surgical evacuation was needed in 4 patients with SDGs. High dynamic accidents and patients with diffuse injury were more prone to SDGs. Close to 8% of SDGs converted themselves into subdural hematomas at approximately 2 months postinjury. Although SDGs developed in 39 (approximately 60%) of 68 post-DC patients, surgical evacuation was needed in only 4.

    Rapid MRI with ultrafast T2 sequences can be performed without sedation and is often used in place of computed tomography (CT) to evaluate pediatric patients for indications such as hydrocephalus. This study investigated the sensitivity of rapid magnetic resonance imaging (MRI) for detection and follow-up of acute intracranial hemorrhage in comparison to CT, which is commonly the first-line imaging. Patients presenting to a pediatric hospital with acute intracranial hemorrhage on CT and follow-up rapid MRI within 48 h were included. Rapid MRI studies consisted of three plane ultrafast T2 sequences either with or without axial gradient echo (GRE) sequences. Identification of hemorrhage on rapid MRI was assessed by readers both blinded and unblinded to prior CT results. One hundred two acute hemorrhages in 61 patients were identified by CT. Rapid MRI detection of subdural and epidural hemorrhages was modest in the absence of prior CT for comparison (sensitivity 61-74 %), but increased with review of the prior CT (sensitivity 80-86 %). Hemorrhage size was a significant predictor of detection (p < 0.0001). Three plane fast T2 images alone without GRE sequences were poor at detecting subarachnoid hemorrhage (sensitivity 10-25 %); rapid MRI with GRE sequences identified the majority of subarachnoid hemorrhage (sensitivity 71-93 %). GRE modestly increased detection of other extra-axial hemorrhages. Rapid MRI with GRE sequences is sensitive for most acute intracranial hemorrhages only when a prior CT is available for review. Rapid MRI is not adequate to replace CT in initial evaluation of intracranial hemorrhages but may be helpful in follow-up of known hemorrhages. (orig.)

    Full Text Available Multiple myeloma is a neoplastic plasma cell disorder. It is characterized by collections of abnormal plasma cells accumulating in the bone marrow, where they interfere with the production of normal blood cells. It usually presents as a multisystemic involvement, whose symptoms and signs vary greatly. Some patients have slowly progressive disease while others have aggressive clinical behavior by extramedullary involvement. In addition to renal failure, anemia, hypercalcemia, lytic bone lesions, and immunodeficiency, it also affects multiple organ system, such as pancreas, adrenal glands, kidney, skin, lung, liver, spleen, lymph nodes, and bone. To raise awareness of the variable presentations of this disease, we report a 53-year-old male patient, with multiple myeloma in his first remission who relapsed with extramedullary plasmacytomas (EMPs involving multiple organs, such as pancreas, adrenal glands, kidney, skin, lung, liver, spleen, and lymph nodes.

    Extramedullary relapses of acute lymphoblastic leukemia (ALL) are rare and usually localized in the central nervous system. We describe such an uncommon case of extramedullary relapse of ALL in the breast of a 44 year old female. The patient, who had been diagnosed with precursor B cell, Philadelphia positive (Ph+) acute lymphoblastic leukemia (ALL) 5 years before and had been in complete molecular remission for the last 19 months, was admitted to the hospital for investigation of a hard, non-tender lump in her right breast. Mammography detected a dense, ill-defined mass, whereas on grey-scale and power Doppler sonography, the appearance of the lesion was consistent with malignancy. Histopathologic and immunohistochemical examination of the specimen demonstrated a similar immunophenotype (CD20+, CD10+, Tdt+, CD3-) as this of the onset ALL cell population in the bone marrow.

    Abstract Background Long term survivorship in total knee arthroplasty is significantly dependant on prosthesis alignment. Our aim was determine which alignment guide was more accurate in positioning of the tibial component in total knee arthroplasty. We also aimed to assess whether there was any difference in short term patient outcome. Method A comparison of intramedullary versus extramedullary alignment jig was performed. Radiological alignment of tibial components and patient outcomes of 103 Triathlon total knee arthroplasties were analysed. Results Use of the intramedullary was found to be significantly more accurate in determining coronal alignment (p = 0.02) while use of the extramedullary jig was found to give more accurate results in sagittal alignment (p = 0.04). There was no significant difference in WOMAC or SF-36 at six months. Conclusion Use of an intramedullary jig is preferable for positioning of the tibial component using this knee system.

    Subdural haematomas are thought to be uncommon in babies born at term. This view is mainly based on findings in symptomatic neonates and babies in whom subdural haemorrhages are detected fortuitously. We aimed to establish the frequency of subdural haemorrhages in asymptomatic term neonates; to study the natural history of such subdural haematomas; and to ascertain which obstetric factors, if any, are associated with presence of subdural haematoma. We did a prospective study in babies who were born in the Jessop wing of the Central Sheffield University Hospitals between March, 2001, and November, 2002. We scanned neonates with a 0.2 T magnetic resonance machine. 111 babies underwent MRI in this study. 49 were born by normal vertex delivery without instrumentation, 25 by caesarean section, four with forceps, 13 ventouse, 18 failed ventouse leading to forceps, one failed ventouse leading to caesarean section, and one failed forceps leading to caesarean section. Nine babies had subdural haemorrhages: three were normal vaginal deliveries (risk 6.1%), five were delivered by forceps after an attempted ventouse delivery (27.8%), and one had a traumatic ventouse delivery (7.7%). All babies with subdural haemorrhage were assessed clinically but no intervention was needed. All were rescanned at 4 weeks and haematomas had completely resolved. Presence of unilateral and bilateral subdural haemorrhage is not necessarily indicative of excessive birth trauma.

    Extramedullary haematopoiesis is sometimes encountered in serve anaemia. Rarely, it may cause neurological symptoms, leading to spinal cord or cauda equina compression. Three patients with thalassaemia intermedia, who developed neurological complications, are described. The diagnoses were based on the clinical findings, computed tomography and magnetic resonance imaging. Small doses of radiotherapy (10-20 Gy in 5-10 fractions) relieved symptoms in all of these patients. Our experience supports the role of radiation therapy as a treatment for this complication.

    Since the first resections of intradural extramedullary neoplasms, neurosurgeons have tended to preserve as much of the integrity of the spine as possible while ensuring a safe corridor to resect these lesions. A dimensional analysis of intradural lesions superimposed on a dimensional analysis of the thoracic canal would provide the anatomical basis for a minimal access approach. The authors report the results of such an analysis on a series of patients with intradural extramedullary lesions. A retrospective analysis was undertaken of 26 thoracic intradural extramedullary lesions managed with open or minimally invasive resection. The size of each lesion was measured in the rostrocaudal, lateral, and anteroposterior dimensions then averaged and compared to reported dimensions of the thoracic spinal canal. The mean (range) dimensions of the surgically resected thoracic lesions were 18.6 mm (10-25 mm) for rostrocaudal, 13.0 mm (7-18 mm) for lateral, and 13.6 mm (9-17 mm) for anteroposterior. No patient had any evidence of thoracic canal remodeling. Thoracic intradural extramedullary lesions become symptomatic as they approach the limits of the thoracic canal, resulting in an inherent dimensional limitation in the rostrocaudal, lateral, and anteroposterior dimensions. Displacement of the spinal cord by the lesion to one side further favors a minimally invasive unilateral approach. A paraspinal unilateral hemilaminectomy approach with a 35×20-mm exposure centered over the lesion offers a safe surgical corridor for resection while preserving the posterior tension band, facet complexes, and paraspinal musculature.

    Full Text Available Extramedullary hematopoiesis (EMH occasionally occurs in patients exhibiting hematological disorders with decreased hematopoietic efficacy. EMH is rarely observed in the spinal epidural space and patients are usually asymptomatic. In particular, in the patients with polycythemia vera, spinal cord compression due to EMH is extremely rare. We report a case of polycythemia vera, in which operative therapy proved to be an effective treatment for myelopathy caused by spinal EMH.

    Full Text Available Abstract Introduction Though uncommon, extramedullary plasmacytoma of the pancreas should be considered in the differential diagnosis of obstructive jaundice and pancreatic neoplasms. This report highlights a case of obstructive jaundice in a 46-year-old West Indian man that resulted from an extramedullary plasmacytoma. Case presentation A 46-year-old West Indian man presented to our hospital with evidence of a significant upper gastrointestinal bleed. He gave a recent history of jaundice, constitutional symptoms and back pain. Ultrasonography revealed a mass in the head of the pancreas with resultant common bile duct dilatation. The patient required urgent surgical intervention for ongoing bleeding at which time a biopsy of the pancreas was taken. Histological analysis revealed a plasmacytoma of the pancreas. A blood film showing rouleaux formation and a skeletal survey demonstrating multiple lytic lesions confirmed multiple myeloma. Before further evaluation or treatment was carried out, the patient defaulted from follow-up and died from his illness seven months later. Conclusion This case represents an example of multiple myeloma with visceral involvement, brought to clinical attention through involvement of the pancreas. The report serves to reaffirm knowledge of the various presentations, the optimal diagnostic tools and the current proposed treatment strategies for extramedullary plasmacytomas of the pancreas.

    Spontaneous acute subdural hematoma is rare and limited to sporadic case reports, associated with neoplasm, aneurysm, arteriovenous malformation and cocaine use. Subdural hematoma has also been reported in association with leukemic malignancies, either during therapy or after diagnosis. However, there are no reports of spontaneous acute subdural hematoma as the primary initial presenting manifestation of a chronic myeloid leukemia. Here we describe one case of a 53-year-old male that presented with severe right-sided headache and intermittent left-sided paresthesias. CT scan showed non-traumatic right-sided acute subdural hematoma. Further evaluation revealed that the patient had chronic myeloid leukemia. His peripheral white blood count normalized after Gleevec and hydroxyurea chemotherapy. Furthermore, he had no neurological deficits after his subdural collection was adequately evacuated.

    Acute subdural hematomas (aSDH) secondary to intracranial aneurysm rupture are rare. Most patients present with coma and their functional prognosis has been classically considered to be very poor. Previous studies mixed good-grade and poor-grade patients and reported variable outcomes. We reviewed our experience by focusing on patients in coma only and hypothesized that aSDH might worsen initial mortality but not long-term functional outcome. Between 2005 and 2013, 440 subarachnoid hemorrhage (SAH) patients were admitted to our center. Nineteen (4.3%) were found to have an associated aSDH and 13 (2.9%) of these presented with coma. Their prospectively collected clinical and outcome data were reviewed and compared with that of 104 SAH patients without aSDH who presented with coma during the same period. Median aSDH thickness was 10mm. Four patients presented with an associated aneurysmal cortical laceration and only one had good recovery. Overall, we observed good long-term outcomes in both SAH patients in coma with aSDH and those without aSDH (38.5% versus 26.4%). Associated aSDH does not appear to indicate a poorer long-term functional prognosis in SAH patients presenting with coma. Anisocoria and brain herniation are observed in patients with aSDH thicknesses that are smaller than those observed in trauma patients. Despite a high initial mortality, early surgery to remove the aSDH results in a good outcome in over 60% of survivors. Aneurysmal cortical laceration appears to be an independent entity which shows a poorer prognosis than other types of aneurysmal aSDH. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The present study aims to investigate 1) the risk factors for hydrocephalus and subdural hygroma (SDG) occurring after decompressive craniectomy (DC), and 2) the association between the type of SDG and hydrocephalus. We retrospectively reviewed the clinical and radiological features of 92 patients who underwent DC procedures after severe head injuries. The risk factors for developing post-traumatic hydrocephalus (PTH) and SDG were analyzed. Types of SDGs were classified according to location and their relationship with hydrocephalus was investigated. Ultimately, 26.09% (24/92) of these patients developed PTH. In the univariate analyses, hydrocephalus was statically associated with large bone flap diameter, large craniectomy area, bilateral craniectomy, intraventricular hemorrhage, contralateral or interhemisheric SDGs, and delayed cranioplasty. However, in the multivariate analysis, only large craniectomy area (adjusted OR=4.66; p=0.0239) and contralateral SDG (adjusted OR=6.62; p=0.0105) were significant independent risk factors for developing hydrocephalus after DC. The incidence of overall SDGs after DC was 55.43% (51/92). Subgroup analysis results were separated by SDG types. Statistically significant associations between hydrocephalus were found in multivariate analysis in the contralateral (adjusted OR=5.58; p=0.0074) and interhemispheric (adjusted OR=17.63; p=0.0113) types. For patients who are subjected to DC following severe head trauma, hydrocephalus is associated with a large craniectomy area and contralateral SDG. For SDGs after DC that occur on the interhemispherical or controlateral side of the craniectomy, careful follow-up monitoring for the potential progression into hydrocephalus is needed.

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012. Univariate and multivariate analyses were performed to determine the relationship between retreatment of bCSDH and clinical, radiological, and surgical variables. RESULTS Two hundred ninety-one patients with bCSDH were identified, and 264 of them underwent unilateral (136 patients) or bilateral (128 patients) surgery. The overall retreatment rate was 21.6% (57 of 264 patients). Cases treated with unilateral surgery had twice the risk of retreatment compared with cases undergoing bilateral surgery (28.7% vs 14.1%, respectively, p = 0.002). In accordance with previous studies, the data also showed that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical procedure.

    Placement of a subdural drain after drainage of chronic subdural haematoma (CSDH) has been shown to reduce the rate of recurrence in several randomised controlled trials (RCT). The most recently published RCT was from Cambridge, UK, in 2009. Despite class I evidence for the use of subdural drains, it is unclear whether these results have been translated into clinical practice. In this clinical audit we review the use of subdural drains in our institution before and after the publication of the 2009 RCT results. A longitudinal retrospective study was performed on all adults having burr holes for CSDH between January 2009 and January 2014. Case notes were analysed to determine subdural drain use, re-operation for CSDH recurrence and post-operative complications. The audit loop was closed with data collected from August 2015 to January 2016. Thirty-one per cent of patients had subdural drains placed at operation. Drain placement was associated with lower reoperation rates (8% vs. 17%, p = 0.021) without increasing complication rates. Drain usage doubled after publication of the Santarius et al. (2009) trial but we observed persisting and significant variability in drain utilisation by supervising consultants. The use of drains in the department increased from 35% to 75% of all cases after presentation of these results. The use of subdural drains in our unit reduced recurrence rates following drainage of CSDH and reproduced the results of a 2009 clinical trial. Although the use of subdural drains doubled in the post-trial epoch, significant variability remains in practice. Clinical audit provided an effective tool necessary to drive the implementation of subdural drain placement in our unit.

    Full Text Available In total knee arthroplasty, mechanical alignment guides have improved the accuracy of implant alignment, but errors are not uncommon. In the present study, an image-free computer-assisted navigation system was used to analyse the accuracy of an extramedullary (tibial alignment system, which is based on predetermined, fixed anatomical landmarks. Comparisons were made between two surgeons, with different levels of competency in order to determine if experience affected the accuracy of extramedullary tibial jig placement, in either the coronal and sagittal planes or both planes. The results showed that the accuracy of the extramedullary tibial alignment system, in the coronal plane (in up to 80-87% of cases was much better than for posterior slope, and sagittal plane. Surgeon experience was not a significant factor.

    Full Text Available Objective: The treatment of subtrochanteric fractures is challenging and treatment modalities and implants are constantly evolving. This study attempts to revisit and compare extramedullary vs. intramedullary devices in relatively young population. Methods: Thirty patients with subtrochanteric fractures were enrolled and treated with extramedullary or intramedullary devices and follow-up continued one year for clinico-radiological assessment. Results: The mean age of patients was 37.53 years. Most were males between 21-40 years old. The dominant mode of injury was traffic accidents (66%. Fractures were classifi ed according to Russell-Taylor classifi cation. Forty percent were Russell-Taylor type IA, 37% type IB and 23% type IIA. Average time to surgery was 3.6 days from the time of admission to hospital. Mean duration of surgery was 45 minutes for intramedullary device (group A and 105 minutes for extramedullary device (group B. Average blood loss was 100 ml in group A and 200 ml in group B. Mean duration of radiation exposure was 130 seconds and 140 seconds for groups A and B, while average duration of hospital stay was 12 days and 16 days respectively. Excellent results were seen in 47% of cases in group A and 33% of cases in group B. Conclusion: Intramedullary device is a reliable implant for subtrochanteric fractures. It has high rates of union with minimal soft-tissue damage. Intramedullary fixation has biological and biomechanical advantages, but surgery is technically demanding. Gradual learning and patience is needed to make this method truly rewarding. Key words: Subtrochanteric fractures; Intramedullary; Dynamic hip screw

    Full Text Available Extramedullary hematopoiesis (EMH is the production of hematopoietic precursors outside the bone marrow cavity, and it causes mass effects according to its localization. Magnetic resonance imaging (MRI and/or computed tomography (CT scans are used most commonly to detect EMH foci. We report herein a case with thalassemia intermedia causing paravertebral mass associated with EMH detected by CT scan. We further evaluated the case with positron emission tomography (PET CT, and lung cancer, which was not revealed in the CT scan, was detected coincidentally.

    Full Text Available Introduction Extramedullary hematopoiesis (EMH commonly occurs in the spleen, liver and lymph nodes. Rare cases of EMH in the adrenal gland have been reported. Case Presentation We report the case of a 33-year-old man from the South of Iran suffering from major β-thalassemia, who underwent open left adrenalectomy and the histopathology revealed EMH. Conclusions In patients in which a history of hematologic disorders exists, careful imaging and hormonal assay should be done to certify a diagnosis of EMH. However, the surgical management becomes inevitable in certain cases.

    Intracranial involvement in extramedullary hematopoiesis (EMH) is rare, but it should be suspected in patients with myelofibrosis presenting with chronic severe headache. We present a 9-year-old girl with known myelofibrosis whose headaches were unresponsive to routine treatment. CT and MRI studies of the brain showed diffuse pachymeningeal thickening. CT examinations of the chest and abdomen had demonstrated bilateral thoracic paraspinal masses caused by EMH, suggesting the possibility that the intracranial involvement might also be related to EMH. The diagnosis was confirmed by sulfur colloid isotope scan. (orig.)

    Metastases to the spinal cord from glioblastoma multiforme (GBM) are uncommon, but important to have in mind when patients with a history of GBM present with symptoms that do not correlate with the primary disease pattern. We report a rare case, where a male with GBM, six months after tumour excision followed by concomitant radio- and chemotherapy, presented with gait disturbance and unspecific neurological symptoms of the lower right limb. Magnetic resonance imaging of columna totalis revealed both intra- and extramedullary metastases in the spinal cord. The patient died one month later.

    Extramedullary hematopoiesis (EMH) is a compensatory mechanism occurring in patients with chronic anemia. Liver, spleen, and lymph nodes are frequently involved. However, EMH may also develop in several sites such as thymus, kidneys, retroperitoneum, paravertebral areas of the thorax, lungs, bowel and others. Rarely symptomatic, it often shows a variety of clinical features. This condition, frequently, may be fatal. A correct early diagnosis of EHM might avoid, if possible, a bad prognosis. The Authors report a case where bone marrow cells were identified in centrifuge cerebrospinal fluid of a patient suffering from non-Hodgkin lymphoma.

  1. Gamma and other cephalocondylic intramedullary nails versus extramedullary implants for extracapsular hip fractures in adults.

    Two types of implants used for the surgical fixation of extracapsular hip fractures are cephalocondylic intramedullary nails, which are inserted into the femoral canal proximally to distally across the fracture, and extramedullary implants (e.g. the sliding hip screw). To compare cephalocondylic intramedullary nails with extramedullary implants for extracapsular hip fractures in adults. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (June 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 2), MEDLINE (1966 to June week 3 2007), EMBASE (1988 to 2007 Week 27), the UK National Research Register, orthopaedic journals, conference proceedings and reference lists of articles. All randomised and quasi-randomised controlled trials comparing cephalocondylic nails with extramedullary implants for extracapsular hip fractures. Both authors independently assessed trial quality and extracted data. Wherever appropriate, results were pooled. Predominantly older people with mainly trochanteric fractures were treated in the 36 included trials.Twenty-two trials (3871 participants) compared the Gamma nail with the sliding hip screw (SHS). The Gamma nail was associated with an increased risk of operative and later fracture of the femur and an increased reoperation rate. There were no major differences between implants in the wound infection, mortality or medical complications.Five trials (623 participants) compared the intramedullary hip screw (IMHS) with the SHS. Fracture fixation complications were more common in the IMHS group; all cases of operative and later fracture of the femur occurred in this group. Results for post-operative complications, mortality and functional outcomes were similar in the two groups. Three trials (394 participants) showed no difference in fracture fixation complications, reoperation, wound infection and length of hospital stay for proximal femoral nail (PFN) compared with the SHS

    1988-10-01

    Osteomyelitis and intracranial abscess are among the most serious complications that have been reported in association with the use of the halo device. The cases of five patients who had formation of an intracranial abscess related to the use of a halo cervical immobilizer are described. All of the infections resolved after drainage of the abscess, débridement, and parenteral administration of antibiotics. Meticulous care of the pin sites is essential to avoid this serious complication. Additionally, since all of the infections were associated with prolonged halo-skeletal traction, this technique should be used with caution and with an awareness of the possible increased risks of pin-site infection and of formation of a subdural abscess.

    PURPOSE: This study aimed to assess the usefulness of Danish patient registers for epidemiological studies of subdural hematoma (SDH) and to describe clinical characteristics of validated cases. METHODS: Using a patient register covering a geographically defined area in Denmark, we retrieved...... hospital contacts recorded under SDH International Classification of Diseases version 10 codes S065 and I620 in 2000-2012. Neurosurgeons reviewed medical records of all potential cases. Based on brain scan results, verified cases were classified by SDH type (chronic SDH (cSDH) or acute SDH (aSDH)). Thirty......-day mortality and preadmission antithrombotic drug use were established through linkage to population-based registers. We calculated the positive predictive value of the SDH code and compared mortality and preadmission antithrombotic drug use of cSDH with those of aSDH (age-adjusted and sex-adjusted odds ratio...

    A 52-year-old woman treated for acute myeloproliferative disease developed progressive stupor. CT showed obstructive hydrocephalus resulting from unexplained mass effect on the fourth ventricle. MRI revealed bilateral extra-axial collections in the posterior cranial fossa, giving high signal on T1- and T2-weighted images, suggesting subacute subdural haematomas. Subdural haematomas can be suspected on CT when there is unexplained mass effect. MRI may be essential to confirm the diagnosis and plan appropriate treatment. (orig.)

    2011-03-01

    The purpose of this study was to assess for peri-operative factors associated with brain shift following craniotomy for subdural grid electrode placement. A retrospective analysis of cases operated at a single institution was undertaken, examining 63 consecutive patients undergoing craniotomy for subdural grid placement for seizure monitoring between 2001 and 2007. Peri-operative records were reviewed in order to assess for intraoperative employment of osmotic duiresis. Postoperative MRI scans were analyzed for shift of the midline and brain displacement. One patient was excluded due to gross hemispheric atrophy confounding the midline, and four patients were excluded due to lack of available imaging. Hence 58 patients were radiographically reviewed. The employment of osmotic diuresis during grid placement appeared to be the most significant peri-operative factor influencing brain shift. Osmotic diuresis was administered in only 14 patients. Midline shift of the third ventricle was greater in the osmotic diuresis group (2.3 ± 0.3 mm vs. 1.5 ± 0.2 mm, p = 0.037). Moreover, the volume of shifted brain was significantly higher in the osmotic diuresis group (7.9 ± 0.5 cm(3) vs. 4.7 ± 0.5 cm(3), p = 0.003). There was no significant difference in the rates of neurological complications between patients who received osmotic diuresis and those who did not. Employment of osmotic diuresis during grid placement appears to be associated with a paradoxical increase in the volume of shifted brain. This may be due to a combination of the resultant "sagging" of the brain and the pressure exerted by the grid, suggesting that osmotic diuresis might not improve mass effect as intended when employed within this context.

    2001-09-01

    In Junwakai Memorial Hospital, from May, 2000 to April, 2001, 1042 patients underwent MRI examination to detect intracerebral microbleed (MB). This series included 481 hypertensive cases and 109 intra-cerebral and cerebellar hemorrhage patients. MB was identified by MRI GRASS image that detects hemosiderin with high sensitivity. The occurrence of MB is high in men and increased with the age. The hypertensive patients showed increased frequency of MB in proportion to the duration of hypertension. Almost all of the symptomatic cerebral and cerebellar hemorrhage cases showed multiple MBs except for massive hemorrhagic lesions. Therefore, MB can be an antecedant feature of the inpending symptomatic intracerebral and cerebellar hemorrhages. (author)

    Accumulating evidence indicates that enhancer of zeste homolog 2 (EZH2) promotes the metastatic ability of solid tumors, but the role of EZH2 in extramedullary infiltration (EMI) in acute myeloid leukemia (AML) has not been thoroughly explored. In the present study, we investigated the possible association between EZH2 and EMI. We found that the messenger RNA (mRNA) and protein expression levels of EZH2 in AML patients were both significantly higher than in idiopathic thrombocytopenic purpura (ITP) patients. Furthermore, a positive correlation between EZH2 mRNA expression and percentage of peripheral blood blasts wa s found in AML patients (r = 0.404, p = 0.009). The migratory capacities of Kasumi-1 and HL-60, which both show a high level of EZH2 expression, were markedly higher than those of U937 and KG-1α. In contrast, silencing of EZH2 resulted in reduction in proliferation and migration ability and an increase in apoptosis. The latter observation was accompanied by reduced expression of associated proteins p-ERK, p-cmyc, and matrix metalloproteinase 2 (MMP-2) and an increase in epithelial cadherin (E-cadherin). These data suggest that higher expression of EZH2 may be associated with extramedullary infiltration in acute myeloid leukemia and affect pathogenesis via activation of the p-ERK/p-cmyc/MMP-2 and E-cadherin signaling pathways.

    Full Text Available Objective and Importance: Malignant pleural effusions occur in the setting of both solid and hematologic malignancies. Pleural effusion caused by leukemic infiltration is an unusual extramedullary manifestation of acute myeloid leukemia (AML with fewer than 20 cases reported.1-11 We report a case of pericardial and pleural effusions in a patient with AML and review the literature. Clinical presentation: In this case, a 55 year old man with previous history of myeloproliferative neoplasm (MPN experienced transformation AML, heralded by appearance of leukemic pleural effusions. The patient was identified to have leukemic pleural effusion based upon extended cytogenetic analysis of the pleural fluid, as morphologic analysis alone was insufficient. Intervention: The patient was treated with hypomethylator-based and intensive chemotherapy strategies, both of which maintained resolution of the effusions in the remission setting. Conclusion: Due to the rarity of diagnosis of leukemic pleural effusions, both cytogenetic and fluorescence in situ hybridization (FISH testing are recommended. Futhermore, systemic chemotherapy directed at the AML can lead to complete resolution of leukemic pleural effusions. Objective and ImportancePleural effusion caused by leukemic infiltration is an unusual extramedullary manifestation of acute myeloid leukemia (AML, but may be more common than previously thought. Fewer than 20 cases have been reported.1-11 We report a case of pericardial and pleural effusions in a patient with AML and review the literature.

    Patient: Male, 41 Final Diagnosis: Healty Symptoms: Headache Medication: — Clinical Procedure: Chronic subdural hematoma Specialty: Neurosurgery Objective: Diagnostic/therapeutic accidents Background: Chronic subdural hematoma generally occurs in the elderly. After chronic subdural hematoma evacuation surgery, the development of epidural hematoma is a very rare entity. Case Report: We report the case of a 41-year-old man with an epidural hematoma complication after chronic subdural hematoma evacuation. Under general anesthesia, the patient underwent a large craniotomy with closed system drainage performed to treat the chronic subdural hematoma. After chronic subdural hematoma evacuation, there was epidural leakage on the following day. Conclusions: Although trauma is the most common risk factor in young CSDH patients, some other predisposing factors may exist. Intracranial hypotension can cause EDH. Craniotomy and drainage surgery can usually resolve the problem. Because of rapid dynamic intracranial changes, epidural leakages can occur. A large craniotomy flap and silicone drainage in the operation area are key safety points for neurosurgeons and hydration is essential. PMID:26147957

    Anti-CD19 chimeric antigen receptor (CAR) T cells have shown promise in the treatment of B cell acute lymphocytic leukemia (B-ALL). However, its efficacy in B-ALL patients with extramedullary involvement is limited due to poor responses and neurotoxicity. Here, we utilized a third generation of CAR T cell vector, which contains the Toll/interleukin-1 receptor (ITR) domain of Toll-like receptor 2 (TLR2), to generate 1928zT2 T cells targeting CD19, and evaluated the efficacy of 1928zT2 T cells in relapse or refractory B-ALL patients with extramedullary involvement. 1928zT2 T cells were generated by 19-28z-TLR2 lentiviral vector transfection into primary human T lymphocytes. The anti-leukemia effect of 1928zT2 T cells were determined by killing assays and in xenografts. Three patients diagnosed as relapse or refractory ALL with extramedullary involvement were infused with 1928zT2 T cells, and the clinical responses were evaluated by BM smear, B-ultrasonography, PET/CT, histology, flow cytometry, qPCR, ELISA, and luminex assay. 1928zT2 T cells exhibited enhanced effector function against CD19+ leukemic cells in vitro and in a xenograft model of human extramedullary leukemia. Notably, the 1928zT2 T cells eradicated extramedullary leukemia and induced complete remission in the three relapse and refractory ALL patients without serious adverse effects. 1928zT2 T cells expanded robustly in the circulation of these three patients and were detected in the cerebrospinal fluid of patient 3. These three patients experienced cytokine release syndrome (CRS) with grade 2 or 3, which remitted spontaneously or after tocilizumab treatment. None of the three patients suffered neurotoxicity or needed further intensive care. Our results demonstrate that 1928zT2 T cells with TLR2 incorporation augment anti-leukemic effects, particularly for eradicating extramedullary leukemia cells, and suggest that the infusion of 1928zT2 T cells is an encouraging treatment for relapsed/refractory ALL

    2013-01-01

    Full Text Available Aim: To evaluate the utility of a mobile device to detect and assess intracranial hemorrhage (ICH on head computed tomographys (CT performed in the emergency setting. Materials and Methods: 100 head CT scans were randomly selected from our emergency radiology database and anonymized for patient demographics and clinical history. The studies were independently interpreted by two experienced radiologists in a blinded manner, initially on a mobile device (iPad, Apple computers and subsequently, at an interval of one week, on a regular desktop workstation. Evaluation was directed towards detection, localization and characterization of hemorrhage. The results were assessed for accuracy, sensitivity, specificity and positive predictive value. Statistical significance was ascertained using Fisher′s exact test. Results: 27 of the examinations were positive for ICH, of which 11 had multiple hemorrhages. Of these there were 17 subdural, 18 intraparenchymal, 8 subarachnoid, 4 intraventricular and 2 extradural hemorrhages. In 96 of the studies there was complete concurrence between the iPad and desktop interpretations for both radiologists. Of 49 hemorrhages, 48 were accurately detected on the iPad by one of the radiologists. In the remaining case, a tiny intraventricular hemorrhage was missed by both radiologists on the iPad as well as on the workstation, indicating that the miss was more likely related to the very small size of the hemorrhage than the viewer used. Conclusion: We conclude that in the emergency setting, a mobile device with appropriate web-based pictue archiving and communication system (PACS is effective in the detection of intracranial hemorrhage present on head CT.

    Metrizamide CT cisternograms (CTC) were performed in order to examine the CSF passage to subarachnoid space, cerebral sulci and Sylvian fissure. The old aged 20 patients (from 63 to 88 years old) with the layer of low density area around bilateral frontal lobe (bi-frontal LDA) in plain CT finding were selected from 2000 aged patients hospitalized in Hanwa-Senboku Hospital. In these 20 patients, it was difficult to differentiate frontal lobe atrophy from the chronic subdural hematoma and subdural hygroma. Conservative therapy was applied in 19 patients for their old age or their complicated diseases. Only 1 patient was operated for subdural hygroma. The 20 patients were investigated in EEGs, severity of dementia, disturbance of consciousness, activity of daily life, their clinical course and prognosis. Only 2 of the 11 patients with type 1 CTC findings (cerebral sulci, Sylvian fissure and bi-frontal LDA were simultaneously enhanced by metrizamide) showed disturbance of consciousness and/or delirium for their serious somatic disorders. All of 6 patients with type 3 CTC findings (only bi-frontal LDA was not enhanced by metrizamide) showed disturbance of consciousness. Three patients with type 2 CTC findings (atypical findings) were reported independently. Subdural disorder elevating intracranial pressure were clarified in the cases with type 3 CTC findings.

    Myeloproliferative neoplasia (MPN)-associated pulmonary hypertension (PH) is included in group five of the most recent clinical classification of PH.(1) The MPNs are a heterogeneous group of disorders that includes disorders with primary expression of a myeloid phenotype and disorders characterized by expression of the Janus Kinase 2 (JAK2) mutation, p.V617F. The latter includes essential thrombocytosis, polycythemia vera, and idiopathic myelofibrosis.(2) Pulmonary extra-medullary hematopoiesis (EMH) refers to the presence of hematopoietic precursor cells in the lung. It is a rare complication associated with myelofibrosis. Here we present a case series highlighting the clinical-pathological-radiological features of pulmonary EMH and PH from underlying polycythemia vera.

    Splenic erythropoiesis was demonstrated by surface counting of {sup 59}Fe in 129 of 1,350 ferrokinetic studies performed over a 15 year period. These 129 studies were carried out in 108 patients, including 40 with chronic myelogenous leukemia (CML), 24 with agnogenic myeloid metaplasia (AMM), 18 with polycythemia vera (PV), six with a myelodysplastic syndrome, five with acute leukemia, three with prostate or breast carcinoma, two each with aplastic anemia or Hodgkin's disease, and one each with idiopathic thrombocythemia, multiple myeloma, chronic renal failure, or treated hypopituitarism. Splenomegaly was present in 83% of the studies and hepatomegaly in 72%. Grade II-III myelofibrosis was demonstrated in 62% of the cases. Hepatic erythropoiesis was present in 77% of the studies (only 38% in PV), and marrow erythropoiesis was undetectable in 33%. Total erythropoiesis was about twice normal (range 0.2 to 8 times normal) but was ineffective to varying degrees in 86% of the studies. Relationships between organomegaly, myelofibrosis, and extramedullary erythropoiesis, as well as differences among clinical disorders, are discussed. Differences observed between CML in chronic or blastic phase suggested that the erythroid cell line was involved in the proliferative process. It is concluded that splenic erythropoiesis (1) is encountered in a variety of clinical conditions; (2) is not necessarily associated with splenomegaly or myelofibrosis, even in the myeloproliferative disorders; (3) is part of a predominantly extramedullary (in the liver as well as in the spleen), expanded, and largely inefficient total erythropoiesis; and (4) can be evaluated in a semiquantitative manner by surface counting.

    C-X-C-motif chemokine receptor 4 (CXCR4) is a key factor for tumor growth and metastasis in several types of human cancer. We have recently reported promising first-in-man experience with CXCR4-directed endoradiotherapy (ERT) in multiple myeloma (MM). Eight heavily pretreated MM patients underwent a total of 10 ERT cycles (7 patients with 1 cycle and a single patient with 3 cycles). ERT was administered in combination with chemotherapy and autologous stem cell support. End points were occurrence and timing of adverse events, progression-free and overall survival. ERT was overall well tolerated without any unexpected acute adverse events or changes in vital signs. With absorbed tumor doses >30-70 Gy in intra- or extramedullary lesions, significant anti-myeloma activity was observed with 1 patient achieving complete remission and 5/8 partial remission. Directly after ERT major infectious complications were seen in one patient who died from sepsis 22 days after ERT, another patient with high tumor burden experienced lethal tumor lysis syndrome. Median progression-free survival was 54 days (range, 13-175), median overall survival was 223 days (range, 13-313). During follow-up (6 patients available), one patient died from infectious complications, 2/8 from disease progression, the remaining 3/8 patients are still alive. CXCR4-directed ERT was well-tolerated and exerted anti-myeloma activity even at very advanced stage MM with presence of extramedullary disease. Further assessment of this novel treatment option is highly warranted.

    Full Text Available Background. Large craniotomy for acute subdural hematoma is sometimes too invasive. We report good outcomes for two cases of neuroendoscopic evacuation of hematoma and contusion by 1 burr hole surgery. Case Presentation. Both patients arrived by ambulance at our hospital with disturbed consciousness after falling. Case 1 was an 81-year-old man who took antiplatelet drugs for brain infarction. Case 2 was a 73-year-old alcoholic woman. CT scanning showed acute subdural hematoma and frontal contusion in both cases. In the acute stage, glycerol was administered to reduce edema; CTs after 48 and 72 hours showed an increase of subdural hematoma and massive contusion of the frontal lobe. Disturbed consciousness steadily deteriorated. The subdural hematoma and contusion were removed as soon as possible by neuroendoscopy under local anesthesia, because neither patient was a good candidate for large craniotomy considering age and past history. 40%~70% of the hematoma was removed, and the consciousness level improved. Conclusion. Neuroendoscopic removal of acute subdural hematoma and contusion has advantages and disadvantages. For patients with underlying medical issues or other risk factors, it is likely to be effective.

    Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment.

    The aim of the present study was to explore the clinical effects, including the prevention of complications, of the treatment of chronic subdural hematoma with double needle aspiration. The clinical data of 31 patients with chronic subdural hematoma treated by double YL-1 needle double skull drilling and 31 controls treated by traditional drilling and drainage were analyzed retrospectively. In the YL-1 needle group, only 1 patient was with hematoma recurrence, 1 patient was with intracranial pneumocephalus, and the remaining patients who were followed up for 3 months achieved a clinical cure. In the traditional drilling and drainage group, 13 patients were with hematoma recurrence within 3 months after the operation and 7 patients were with postoperative intracranial pneumocephalus. The method of double YL-1 needle is better than the traditional drilling and drainage method for the treatment of chronic subdural hematoma because it reduces the postoperative recurrence rate and complications.

    2014-03-08

    Acquired hemophilia A (AHA) is a rare coagulopathy linked to a variety of etiologies including autoimmune diseases, neoplasms, diabetes, respiratory diseases, and the post-partum state. While bleeding in AHA is often seen in mucocutaneous or intramuscular locations, intracranial and intraspinal bleeds are exceedingly rare. We report an unusual case of spontaneous multifocal subdural hematomas in a 25 year old Asian woman with lupus who presented with headache and backache, and was found to have an elevated partial thromboplastin time (PTT) level and new diagnosis of AHA. Subdural hematomas as the initial sign of AHA are all but unknown in the medical literature. We bring this entity to the attention of the neurology community because lumbar puncture and/or conventional angiogram are often indicated in the work-up of idiopathic multifocal subdural hematomas, but may be dangerous in patients with AHA.

  9. Recurrence of Subdural Haematoma in a Population-Based Cohort - Risks and Predictive Factors.

    Full Text Available To estimate the risks of and identify predictors for recurrent subdural haematoma in surgically and conservatively treated patients.The cohort comprised all individuals diagnosed with a first-time subdural hematoma in Denmark 1996-2011. Information on potential predictors was retrieved from the Danish health registers. Cumulative recurrence risks were estimated using the Aalen-Johansen estimator. Rate ratios (RR were estimated using Poisson regression.Among 10,158 individuals with a subdural hematoma, 1,555 had a recurrent event. The cumulative risk of recurrent subdural hematoma was 9% at 4 weeks after the primary bleeding, increasing to and stabilising at 14% after one year. Predictors associated with recurrence were: Male sex (RR 1.60, 95% CI:1.43-1.80, older age (>70 years compared to 20-49 years; RR 1.41, 95% CI: 1.21-1.65, alcohol addiction (RR 1.20, 95% CI:1.04-1.37, surgical treatment (RR 1.76, 95% CI:1.58-1.96, trauma diagnoses (RR 1.14, 95% CI:1.03-1.27, and diabetes mellitus (RR 1.40, 95% CI:1.11-1.74. Out of a selected combination of risk factors, the highest cumulative 1-year recurrence risks for subdural hematoma of 25% (compared to 14% for all patients was found in surgically treated males with diabetes mellitus.The recurrence risk of subdural hematoma is largely limited to the first year. Patient characteristics including co-morbidities greatly influence the recurrence risk of SDH, suggesting that individualized prognostic guidance and follow-up is needed.

    A long-term follow-up of a patient with beta thalassaemia with intra- and extraspinal extramedullary haematopoietic tissue compressing the spinal cord is presented. Extramedullary haematopoietic nodules are a rare cause of spinal cord compression and should be included in the differential diagnosis, especially in patients from Mediterranean countries. Treatment with radiation therapy solely failed, giving rise to the need of surgical intervention. Surgical decompression of the spine and the removal of the culprit lesion compressing the spine were performed. Postinterventional radiation therapy was applied to the spine. A relapse had to be treated again by surgical means combined with postinterventional radiation therapy. A complete relief of the symptoms and control of the lesion could be obtained.

    2011-01-01

    Full Text Available Extramedullary deposits may be the presenting feature of acute myeloid leukemia. An early and accurate diagnosis on cytology will aid in correct patient management. This is especially true for patients with acute megakaryoblastic leukemia (AML M7, where bone marrow aspiration may yield only a dry tap. While cytomorphological features of myeloid sarcoma of other types are well recognized due to its rarity, there are only two case reports discussing the morphological details of megakaryoblastic differentiation on aspiration cytology. We present the case of a 25-year-old patient with extramedullary involvement of lymph node and cerebrospinal fluid by AML M7, describing in detail, the morphological features on aspiration as well as exfoliative cytology.

    T-cell acute lymphoblastic leukemia is a hematologic malignancy with propensity to involve extramedullary organs including the eyes. Optic nerve infiltration is relatively rare. This is the case study of a 25-year-old- man who was in full remission following treatment for T-cell acute lymphoblastic leukemia and presented with bilateral leukemic optic nerve infiltration as the first manifestation of extramedullary relapse. The patient was treated with urgent radiotherapy and systemic dexamethasone. Over the following period, gradual resolution of optic disc swelling was noted in both eyes with marked improvement in vision in the right eye. Unfortunately, a few weeks later, a full blown hematological relapse was diagnosed. Salvage chemotherapy was instituted but was complicated by tumor lysis syndrome and septicemia that proved to be fatal. Ophthalmic assessment is essential in patients with hematological malignancies in order to diagnose ocular involvement as a result of malignant infiltration, hematological disturbances or as a complication of systemic therapy.

    Full Text Available Spinal subdural hematoma is a rare disorder and can be caused by abnormalities of coagulation, blood dyscrasias, lumbar puncture, trauma, underlying neoplasm, and arteriovenous malformation. We discuss an unusual case of an elderly woman who presented with spontaneous spinal subdural hematoma and developed massive rebleeding on the third day following initial evacuation of hematoma. This case illustrates that a patient with routine normal coagulation profile and adequate hemostasis can still harbor platelet dysfunction (in present case due to polycythemia and later on can manifest as rebleeding and neurological deterioration.

    Full Text Available An 80-year-old man was admitted for acute subdural hematoma caused by a mild brain injury. His coagulation test showed an isolated prolongation of activated partial thromboplastin time (aPTT. Though the subdural hematoma did not progress, oozing bleed from the wound of tracheostomy continued. Failure of correction on aPTT mixing test supported the presence of an inhibitor to a coagulation factor. Once the diagnosis of acquired hemophilia A (AHA was made, steroid therapy was performed, which leads him to complete remission of AHA. Isolated prolongation of aPTT can be the key to diagnose a rare coagulopathy, such as AHA.

    Although the incidence of subdural hematoma (SDH) has increased in the US in the last decade, limited prospective data exist examining risk factors for poor outcome. A prospective, observational study of consecutive SDH patients was conducted from 7/2008 to 11/2011. Baseline clinical data, hospital and surgical course, complications, and imaging data were compared between those with good versus poor 3-month outcomes (modified Rankin Scores [mRS] 0-3 vs. 4-6). A multivariable logistic regression model was constructed to identify independent predictors of poor outcome. 116 SDH patients (18 acute, 56 mixed acute/subacute/chronic, 42 subacute/chronic) were included. At 3 months, 61 (53 %) patients had good outcomes (mRS 0-3) while 55 (47 %) were severely disabled or dead (mRS 4-6). Of those who underwent surgical evacuation, 54/94 (57 %) had good outcomes compared to 7/22 (32 %) who did not (p = 0.030). Patients with mixed acuity or subacute/chronic SDH had significantly better 3-month mRS with surgery (median mRS 1 versus 5 without surgery, p = 0.002) compared to those with only acute SDH (p = 0.494). In multivariable analysis, premorbid mRS, age, admission Glasgow Coma Score, history of smoking, and fever were independent predictors of poor 3-month outcome (all p SDH evacuation tended to improve outcomes (adjusted OR 3.90, 95 % CI 0.96-18.9, p = 0.057). Nearly 50 % of SDH patients were dead or moderate-severely disabled at 3 months. Older age, poor baseline, poor admission neurological status, history of smoking, and fever during hospitalization predicted poor outcomes, while surgical evacuation was associated with improved outcomes among those with mixed acuity or chronic/subacute SDH.

    Vasospasm is the most common cause of complication after a subarachnoid hemorrhage and tremendous efforts have been made to prevent it. A subarachnoid clot is the cause of the vasospasm and dissolving and washing it out is considered to be the best practice. Cisternal irrigation with urokinase and ascorbic acid has been widely used due to its proven effect. A 60-year-old Japanese male presented with a severe headache was diagnosed with a subarachnoid hemorrhage and an immediate surgical obliteration was successfully performed. After clipping the aneurysm, a cisternal drainage tube was placed in the chiasmatic cistern. In order to clear the thick subarachnoid hemorrhage, a cisternal irrigation was performed. However, his consciousness deteriorated and his left pupil became dilated on the next day. A T1 sagittal magnetic resonance imaging scan showed an evidence of marked brain sagging with mild tonsillar descent. We continued intensive hydration and head-down positioning and the brain sagging was shown to have improved in the follow-up magnetic resonance imaging scan. We present a case in which our patient experienced brain sagging after a cisternal irrigation of a subarachnoid hemorrhage. A subdural hematoma and low intracranial pressure suggested intracranial hypotension. Sagittal magnetic resonance imaging images are useful to evaluate brain sagging and are shown sequentially here in our case report.

    We present the case of a 42-year-old man with a painful mass lesion in the right shoulder that was detected by contrast-enhanced computed tomography (CT) and {sup 18}F-fluoro-2-deoxyglucose ({sup 18}F-FDG) positron emission tomography (PET)/CT. Excisional biopsy revealed infiltration of plasma cells with anaplastic features, consistent with solitary plasmacytoma (PC). Serum analysis showed elevation of serum free lambda light chain levels (27.78 mg/l), with an abnormally high kappa:lambda ratio (2.33) and high total proteins (10.4 g/dl). Serum protein electrophoresis revealed an M spike in the gamma-globulin region (56.1 %=5.8 g/dl). Subsequently, {sup 18}F-FDG PET/CT revealed another hypermetabolic mass in the right lobe of the liver. CT-guided biopsy of the liver lesion revealed plasma cell myeloma, consistent with multiple myeloma. Multiple myeloma presenting as nodular liver masses is very rare in clinical practice. In a retrospective review of more than 2,000 patients, Talamo et al. reported only nine cases where there was nodular involvement of the liver by multiple myeloma. The organ most commonly involved was the liver, followed by pancreas, stomach, peritoneum with malignant ascites, colon, rectum, duodenum and ileum. Therefore, the literature published thus far has been limited to a few reports and case series. Among these reports, some had demonstrated the PET or PET/CT findings of nodular liver involvement of multiple myeloma. About 10 % of the solitary myelomas appeared as extramedullary PC or solitary PC of bone. In spite of the advances in therapy, the treatment of multiple myeloma is still palliative. However, solitary PC could be cured by resection or radiation therapy. Thus, differentiation between PC and multiple myeloma is essential in making a decision for the appropriate therapeutic regimen. {sup 18}F-FDG PET/CT has the unique ability to detect and characterize malignant lesions in one single examination.

    Viral hemorrhagic septicemia (VHS) is one of the most important viral diseases of finfish worldwide. In the past, VHS was thought to affect mainly rainbow trout Oncorhynchus mykiss reared at freshwater facilities in Western Europe where it was known by various names including Egtved disease and infectious kidney swelling and liver degeneration (Wolf 1988). Today, VHS is known as an important source of mortality for cultured and wild fish in freshwater and marine environments in several regions of the northern hemisphere (Dixon 1999; Gagné et al. 2007; Kim and Faisal 2011; Lumsden et al. 2007; Marty et al. 1998, 2003; Meyers and Winton 1995; Skall et al. 2005b; Smail 1999; Takano et al. 2001).

  6. The subdural space of the spine: A lymphatic sink? Myodil's last message.

    Hugh, Alan E

    2010-10-01

    Following the radiological study of a large number of myelograms, starting over 50 years ago when the only clinical contrast medium available to show the contents of the spinal canal was an iodized oil, the author has collected a number of examples where the oil was inadvertently injected into the subdural area, rather than the intended subarachnoid space. By taking follow-up films at various intervals following the inadvertent injection, it has been possible to study the extent to which the subdural space could become visualized from a lumbar injection, the contrast medium sometimes passing to the top of the cervical region and the lower part of the sacrum. Also, the contrast passed outward along the peri-neural lymphatic sheaths or spaces of the issuing spinal nerves, where it might remain for months, and under the influence of gravity it could extend for a considerable way. It also passed into abdominal and thoracic lymph vessels and nodes. Considering the morphology, predictability, and ease with which the demonstrated subdural space fills, the author concludes that the subdural region is a true and functionally significant "space," and an important conduit or functional part of the body's lymphatic system. He also considers that it has implications for the spread or dissemination of various organisms, substances or pathological conditions, as well as being part of the normal conduit for reabsorption of CSF with implications for hydrocephalus, and with potential for misplacement of spinal anaesthetic agents.

    Chronic subdural hematoma pathophysiology has been extensively studied and discussed. In the last decades, optic and electron microscope observations have successfully described its histopathology and the ultrastructure of internal membranes. Moreover, recent biochemical studies have identified a number of important pathways involved in its development and evolution. Our aim was to review recent literature regarding histopathology, ultrastructure and biochemichal pathways and supply a unifying theory about chronic subdural hematoma pathophysiology. The starting point of chronic subdural hematoma is a mechanical injury. The evolution of the pathology is due to the exclusive anatomy of the dura-arachnoid interface. This is a mechanically weak layer. Fibroblasts contained in this region produce an inflammatory reaction with neoangiogenesis and fibrinolysis. Biochemical pathways involved in these reactions is complex and could contain a number of pharmacological targets. The hematoma evolves in different stages thus recent outlooks consider chronic subdural hematoma as a dynamic process. One of the key points for a good outcome and a low recurrence rate may be the timing of the surgical treatment in relation of hematoma natural history. Surgery performed during active inflammatory stages may be less effective in terms of clinical outcome and recurrence rate.

    Water-tight closure of the dura in extracranial-intracranial (EC-IC) bypass is impossible because the superficial temporal artery (STA) must run through the dural defect. Consequently, subdural hygroma and subcutaneous cerebrospinal fluid (CSF) collection frequently occur postoperatively. To reduce these complications, we prospectively performed suturing of the arachnoid membrane after STA-middle cerebral artery (STA-MCA) and evaluated the clinical usefulness. Between Mar. 2005 and Oct. 2010, extracranial-intracranial arterial bypass (EIAB) with/without encephalo-myo-synangiosis was performed in 88 cases (male : female = 53 : 35). As a control group, 51 patients (57 sides) underwent conventional bypass surgery without closure of the arachnoid membrane. Postoperative computed tomography (CT) scan was performed twice in three days and seven days later, respectively, for evaluation of the presence of subdural fluid collection and other mass lesions. The surgical result was excellent, with no newly developing ischemic event until recent follow-up. The additional time needed for arachnoid suture was five to ten minutes, when three to eight sutures were required. Post-operative subdural fluid collection was not seen on follow-up computed tomography scans in all patients. Arachnoid suturing is simple, safe, and effective for prevention of subdural fluid collection in EC-IC bypass surgery, especially the vulnerable ischemic hemisphere.

    Ebola hemorrhagic fever is an often-fatal disease caused by a virus of the Filoviridae family, genus Ebolavirus. Initial signs and symptoms of the disease are nonspecific, often progressing on to a severe hemorrhagic illness. Special Operations Forces Medical Providers should be aware of this disease, which occurs in sporadic outbreaks throughout Africa. Treatment at the present time is mainly supportive. Special care should be taken to prevent contact with bodily fluids of those infected, which can transmit the virus to caregivers. 2014.

    The vast majority of cases of infectious cystitis are easily treated, and most patients have no long-term complications. However, hemorrhagic cystitis is a potentially deadly complication associated with pelvic radiation therapy, chemotherapy, and stem-cell transplant therapy. The focus of current understanding, and hence therapy, is directed toward urothelial cell death. However, the primary functional ramification of inflammatory bladder disease is the loss of compliance due to muscular expansion. Recent studies on smooth muscle response in models of bladder inflammation demonstrate a process of pyroptotic cell death that potentiates further muscle hyperplasia. These findings may support alternative interventions for subjects with hemorrhagic cystitis refractive to current therapy. PMID:25374922

  13. A RARE CASE OF EXTRAMEDULLARY PLASMACYTOMA MASQUERADING AS JUVENILE NASOPHARYNGEAL ANGIOFIBROMA

    Full Text Available BACKGROUND Plasmacytomas are rare plasma cell tumours occurring consequent to monoclonal proliferation of plasma cells. They are divided into Solitary bone plasmacytoma, Extramedullary plasmacytoma (EMP and Multiple myeloma. EMPs are commonly housed in the head and neck region with a predilection to the mucosa associated lymphoid tissue in the aerodigestive tract. The nasal cavity, paranasal sinuses, and nasopharynx are the most common sites. OBJECTIVE We describe our experience with this tumour owing to its clinical rarity and a different way of presentation. METHODS After complete surgical excision of a nasal mass presenting in a young male with features masquerading that of Juvenile Nasopharyngeal Angiofibroma, a diagnosis of plasma cell tumour was made on histopathological analysis which was confirmed using immunohistochemistry. Serum electrophoresis, urine Bence Jones proteins, complete skeletal survey were done to rule out any progression into multiple myeloma. Radiation therapy was given with 45 Gy in 25 fractions at 1.8 Gy per day, 5 days a week. RESULTS Followup after 2 years showed no recurrence locally as well as in regional nodes. CONCLUSION Given to the rarity of the tumour, undefined manner of presentation and a predominant prevalence in the head and neck region, every otolaryngologist should keep EMP in mind while considering sinonasal masses. A multidisciplinary approach with a combination of surgery and radiotherapy is found to benefit the patient significantly. A long term watch out for progression to MM is mandatory to commence early treatment and thus prolonged disease-free survival from the same.

    Full Text Available Extramedullary plasmacytoma (EMP is a rare neoplasm of plasma cells, described in soft tissue outside the bone marrow. EMP of the larynx represents 0.04 to 0.45% of malignant tumors of the larynx. A male of 57 years old presented with hoarseness, dyspnea, and biphasic stridor of 2 months. The indirect laryngoscopy (IL revealed severe edema of the posterior commissure and a polypoid mass in the right posterior lateral subglottic wall. A biopsy of the subglottic mass was performed by a direct laryngoscopy (DL. The histopathologic diagnosis was EMP CD138+, therefore radiotherapy was given at 54 Gy in 30 sessions. The patient had an adequate postoperative clinical course and a new biopsy was performed having tumor-free margins. All laryngeal lesions should be biopsied prior to treatment to determine an accurate diagnosis to guide a proper management of the condition. Radiation therapy to the EMP is considered the treatment of choice, having local control rates of 80% to 100%. The subglottis is the least accessible area of view and the least frequent location of a laryngeal mass, nevertheless the otolaryngologist should always do a complete and systematic exam of the larynx when a tumor is suspected, to detect diagnoses such as a subglottic plasmacytoma.

    Full Text Available Multiple myeloma and other plasma cell disorders are characterized by production of a large number of plasma cells in the bone marrow. On the other hand, plasmacytoma results from proliferation of abnormal plasma cells in the soft tissue or skeletal system. Neurological complications are frequently observed in these diseases. The most commonly known complications among those complications are spine fractures, spinal cord compressions, and peripheral neuropathies. Although neurological involvements are common in plasmacytomas, extramedullary spinal epidural localizations have been reported very rarely. In this case report, we aimed to present a plasmacytoma case that presented with acute onset of upper extremity monoparesis. A 40-year-old woman was admitted to our clinic with complaints of sudden weakness and numbness in her left arm following neck and left arm pain. Emergency cervical magnetic resonance imaging (MRI revealed an epidural mass and the patient underwent emergency surgery. The patient showed improvement post-operatively and the pathology was reported as plasmacytoma. Following hematology consultation, systemic chemotherapy was initiated and radiotherapy was planned after wound healing.

    Objective and Importance: Malignant pleural effusions occur in the setting of both solid and hematologic malignancies. Pleural effusion caused by leukemic infiltration is an unusual extramedullary manifestation of acute myeloid leukemia (AML) with fewer than 20 cases reported (1–11). We report a case of pericardial and pleural effusions in a patient with AML and review the literature. Clinical Presentation: In this case, a 55-year-old man with previous history of myeloproliferative neoplasm experienced transformation AML, heralded by appearance of leukemic pleural effusions. The patient was identified to have leukemic pleural effusion based on the extended cytogenetic analysis of the pleural fluid, as morphologic analysis alone was insufficient. Intervention: The patient was treated with hypomethylator-based and intensive chemotherapy strategies, both of which maintained resolution of the effusions in the remission setting. Conclusion: Due to the rarity of diagnosis of leukemic pleural effusions, both cytogenetic and fluorescence in situ hybridization testing are recommended. Furthermore, systemic chemotherapy directed at the AML can lead to complete resolution of leukemic pleural effusions. PMID:24918086

    Full Text Available Extramedullary hematopoiesis (EMH is a compensatory response to many chronic anemic disorders. Intrathoracic EMH, usually presenting as paravertebral masses over the posterior mediastinum, is a rare entity and is usually asymptomatic. Hemothorax is a rare but possibly fatal complication. Local radiation for intrathoracic EMH is considered effective in preventing its recurrence. Here we describe a patient who had had α-thalassemia for many years and developed a spontaneous left-sided hemothorax from EMH. A chest film and a chest computed tomography (CT scan had showed multiple paravertebral masses over the lower thoracic spine with left-sided pleural effusion. A pathological diagnosis of EMH was made by video-assisted thoracoscopic surgery. The patient had not received preventive local chest radiation. Ten years later, he suffered from a life-threatening hemothorax complicated by acute respiratory failure without traumatic history. A CT scan showed posterior mediastinal masses over the lower thoracic spine with right-sided pleural effusion. Thoracoscopy was performed to remove the blood clot in the pleural space for successful weaning from mechanical ventilation. This is the first case of intrathoracic EMH to have recurrent hemothorax associated with acute respiratory failure.

    To investigate whether, after the publication of grade I evidence that it reduces recurrence rates, the practice of drain insertion after burr-hole drainage of chronic subdural hematoma has changed. Further, we aimed to document various practice modalities concerning the insertion of a drain adopted by neurosurgeons internationally. We administered a survey to neurosurgeons worldwide with questions relating to the surgical treatment of chronic subdural hematoma, with an emphasis on their practices concerning the use of a drain. The preferred surgical technique was burr-hole drainage (89%). Most surgeons prefer to place a drain (80%), whereas in 56% of the cases the reason for not placing a drain was brain expansion after evacuation. Subdural drains are placed by 50% and subperiosteal drains by 27% of the responders, whereas 23% place primarily a subdural drain if possible and otherwise a subperiosteal drain. Three quarters of the responders leave the drain for 48 hours and give prophylactic antibiotic treatment, mostly a single-shot dose intraoperatively (70%). Routine postoperative computed tomography is done by 59% mostly within 24-48 hours after surgery (94%). Adjunct treatment to surgery rarely is used (4%). The publication of grade I evidence in favor of drain use influenced positively this practice worldwide. Some surgeons are still reluctant to insert a drain, especially when the subdural space is narrow after drainage of the hematoma. The insertion of a subperiosteal drain could be a good alternative solution. However, its outcome and efficacy must be evaluated in larger studies. Copyright © 2017 Elsevier Inc.

    To better understand the mechanism of radiation-induced hemorrhagic cystitis and the advantages and disadvantages of available treatment options for bladder hemorrhage as well as preventive measures. There have been several attempts recently to manage hemorrhagic cystitis with hyperbaric oxygen therapy, transurethral coagulation using Greenlight potassium-titanyl-phosphate laser and other different treatment modalities, but we still need more investigation on larger cohort studies. Hemorrhagic cystitis is an uncommon urological problem. It is most often caused by radiation therapy and cyclophosphamide, but can be associated with other contributing factors. Technological advances in radiation therapy have resulted in greater treatment efficacy, with significant reduction in side-effects such as hemorrhagic cystitis. Higher dose radiation treatment, however, is more often associated with problematic hemorrhagic cystitis. Treatment of hemorrhagic cystitis is multifactorial and can range from simple bladder irrigation to cystectomy with urinary diversion.

    Intramedullary neuroepithelial cysts are extremely rare and only 15 cases have been reported in the literature. Clinico-radiological features are not indicative of a specific diagnosis; for this reason, diagnosis is based mainly on the histological features. In the literature, total surgical removal is considered the treatment of choice. The risk of recurrence is higher after partial removal and in cases of occlusion of intra-extramedullary shunt. For this reason, a surgical strategy that ensures the shunt patency in case of incomplete removal of the cyst becomes a very safe option for treatment of this pathology. We report the case of a 51-year-old woman who was found to have a dorsal (D9) intramedullary neuroepithelial cyst. She underwent surgical treatment with partial removal and placement of a Nelaton drainage device (8 French) inside the intra-extramedullary shunt. The patient experienced a complete regression of preoperative symptoms and magnetic resonance imaging (MRI) follow-up showed no radiological evidence of recurrence 24 months after surgical treatment. Spinal ependymal cysts show a high frequency of recurrence, especially in cases of partial removal of the cyst wall. Unfortunately, the cyst walls are often closely adherent to the spinal cord, making total removal impossible. Intra-extramedullary shunting is a viable option, although there is a high frequency of recurrence in cases of obstruction of the shunt. Placing an 8 Ch Nelaton drain between the dorsal columns is a reliable technique, especially in cases of partial removal. In fact, it allows continuous drainage of cyst fluid and subsequent resolution of symptoms, and it decreases the incidence of recurrences due to obstruction of the shunt.

    Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph node chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.

    OBJECT Patients with symptomatic intradural-extramedullary (ID-EM) tumors may be successfully treated with resection of the lesion and decompression of associated neural structures. Studies of patients undergoing open resection of these tumors have reported high rates of gross-total resection (GTR) with minimal long-term neurological deficit. Case reports and small case series have suggested that these patients may be successfully treated with minimally invasive surgery (MIS). These studies have been limited by small patient populations. Moreover, there are no studies directly comparing perioperative outcomes between patients treated with open resection and MIS. The objective of this study was to compare perioperative outcomes in patients with ID-EM tumors treated using open resection or MIS. METHODS A retrospective review was performed using data collected from 45 consecutive patients treated by open resection or MIS for ID-EM spine tumors. These patients were treated over a 9-year period between April 2003 and October 2012 at Northwestern University and the University of Chicago. Statistical analysis was performed to compare perioperative outcomes between the two groups. RESULTS Of the 45 patients in the study, 27 were treated with the MIS approach and 18 were treated with the open approach. Operative time was similar between the two groups: 256.3 minutes in the MIS group versus 241.1 minutes in the open group (p = 0.55). Estimated blood loss was significantly lower in the MIS group (133.7 ml) compared with the open group (558.8 ml) (p spine tumors (OR 15, p = 0.05). CONCLUSIONS Thoracolumbar ID-EM tumors may be safely and effectively treated with either the open approach or an MIS approach, with an equivalent rate of GTR, perioperative complication rate, and operative time. Patients treated with an MIS approach may benefit from a decrease in operative blood loss and shorter hospital stays.

    2016-07-11

    BACKGROUND Myelomatous pleural effusion (MPE) is a rare occurrence in patients with multiple myeloma (MM). Fewer than 20 cases of MPE have been reported as an initial manifestation of MM. Extramedullary plasmacytoma (EMP) occurs in fewer than 5% patients with MM, and mediastinal EMP is even rarer, with only about 80 cases reported in the literature. We present a case study involving a patient with concurrent MPE and mediastinal EMP as an initial manifestation of MM. CASE REPORT The patient was a 74-year-old nonsmoking female with a 3-month history of exertional dyspnea and back pain. On exam, the patient was afebrile (temperature 37.2°C), blood pressure was 160/74 mm Hg, heart rate was 92 bpm, respiratory rate was 22/min, and oxygen saturation was 87% on room air. Patient was in mild distress and had decreased breath sounds over right lung fields about halfway up with dullness to percussion. Computed tomography of the chest showed a moderate-sized right pleural effusion and an anterior mediastinal mass. Thoracentesis showed a lymphocyte-predominant exudate. Cytology showed numerous plasma cells including immature forms. Stains for CD138 were positive, confirming plasma cell origin of cells. The anterior mediastinal mass was also biopsied and showed diffuse infiltrate of lymphocytes with plasma cell features that were also positive for CD138. Systemic protein electrophoresis showed a monoclonal immunoglobulin G kappa spike, and bone marrow biopsy was consistent with MM. CONCLUSIONS MPE and EMP are extremely rare manifestations in MM. In addition, it is extremely rare for these to be the presenting features of MM. We report concurrently occurring MPE and EMP in a patient as her initial manifestation of MM.

    To investigate potential prognostic factors affecting patient outcomes and to evaluate the optimal methods and effects of radiotherapy (RT) in the management of extramedullary plasmacytoma (EMP). Data from 55 patients with EMP between November 1999 and August 2015 were collected. The median age was 51 (range, 22-77) years. The median tumor size was 3.5 (range, 1.0-15.0) cm. The median applied dose was 50.0 (range, 30.0-70.0) Gy. Thirty-nine patients (70.9%) presented with disease in the head or neck region. Twelve patients received RT alone, 9 received surgery (S) alone, 3 received chemotherapy (CT) alone, and 3 patients did not receive any treatment. Combination therapies were applied in 28 patients. The median follow-up duration was 56 months. The 5-year local recurrence-free survival (LRFS), multiple myeloma-free survival (MMFS), progression-free survival (PFS) and overall survival (OS) rates were 79.8%, 78.6%, 65.2% and 76.0%, respectively. Univariate analysis revealed that RT was a favourable factor for all examined endpoints. Furthermore, head and neck EMPs were associated with superior LRFS, MMFS and PFS. Tumor size <4 cm was associated with superior MMFS, PFS and OS; serum M protein negativity was associated with superior MMFS and PFS; age ≥50 years and local recurrence were associated with poor MMFS. The dose ≥45 Gy group exhibited superior 5-year LRFS, MMFS and PFS rates (94.7%, 94.4%, 90.0%, respectively), while the corresponding values for the dose <45 Gy group were 62.5% (P=0.008), 53.3% (P=0.036) and 41.7% (P<0.001). Involved-site RT of at least 45 Gy should be considered for EMP. Furthermore, patients with head and neck EMP, tumor size <4 cm, age <50 years and serum M protein negativity had better outcomes.

    Background: Subacute subdural hematoma (SASDH) is an entity which is yet to capture the popular imagination among the neurosurgeons. Its management is often equated clinically to that of the chronic subdural hematoma (CSDH). However, their neurological deterioration is usually rapid, which seems to align them with acute subdural hematoma (ASDH). We proceed for their epidemiological evaluation. The advantages of a novel "double barrel technique (DbT)" over the conventional burrhole drainage ar...

    Bacterial diarrhea can be classified into two clinical entities, noninflammatory diarrhea and inflammatory diarrhea syndromes. The latter type of diarrhea is characterized by bloody and puruloid mucus stool, and is often accompanied by fever, tenesmus, and severe abdominal pain. Pathogenic bacteria causing the inflammatory diarrhea syndrome include Salmonella, Vibrio, Shigella, enteroinvasive and enterohemorrhagic Escherichia coli, Campylobacter, Yersinia, Chlamydia, and Clostridium difficile. The pathologic changes in the inflammatory diarrhea syndrome range from a superficial exudative enterocolitis to a transmural enterocolitis with overt ulceration. This syndrome is also designated as bacterial hemorrhagic enterocolitis because of its usual manifestation by bloody diarrhea. The diagnostic approach needs information on the patient's age, travel history, epidemiological associations, sexual practice, and medical history, including usage of antibiotics. Bacterial information can be obtained by microscopic study, culture, and the identification of specific bacterial toxins. Flexible colonoscopy with biopsy is useful for the differentiation of bacterial hemorrhagic enterocolitis from idiopathic ulcerative colitis and ischemic colitis. Physicians should be familiar with the diagnostic modalities used to detect the specific pathogens causing hemorrhagic bacterial enterocolitis; namely, bacterial culture, serology, histology, and nucleic acid technologies.

    We investigated the prevalence of intracranial hemorrhage (ICH) before and after neonatal heart surgery. We carried out pre- and postoperative MRI looking for brain lesions in 24 full-term new-borns with known congenital heart disease. They underwent heart surgery with cardiopulmonary bypass (CPB), usually with deep hypothermic circulatory arrest (DHCA). The first MRI was 1-22 days after birth. There were 21 children born after uncomplicated vaginal delivery and three delivered by cesarean section (CS). ICH was seen in 13 (62%) of the vaginal delivery group but in none of the CS group. We saw subdural bleeding along the inferior surface of the tentorium in 11 (52%) and supratentorially in six (29%) of the 21 children with ICH. Small hemorrhages were present in the choroid plexus in seven (33%), in the parenchyma in one (5%) and in the occipital horn in one (5%). There were 26 foci of bleeding in these 21 patients (1.2 per patient). None was judged by formal neurologic examination to be symptomatic from the hemorrhage. Follow-up MRI after cardiac surgery was obtained in 23 children, showing 37 foci of ICH (1.6 per patient), but all appeared asymptomatic. Postoperatively, ICH had increased in 10 children (43%), was unchanged in seven (30%) and was less extensive in six (26%). (orig.)

    Full Text Available Cerebral venous thrombosis is a rare but a serious complication of spinal anesthesia. It usually occurs in the presence of predisposing factors such as pregnancy, puerperium, use of oral contraceptive drugs, malignancies, thrombocytopenia and the most frequent symptom is headache. Twenty-two years of age, pregnant woman had a complaint of headache after spinal anesthesia for caesarean section and diagnosed as post-dural puncture headache, the treatment was begun. After detecting responsiveness to treatment, radiological imaging procedures were performed and subdural hematoma and transverse sinus thrombosis were detected. In this case report, it was concluded under current literatures that the subdural hematoma and transverse sinus thrombosis should be kept in mind during the diagnosis of post-dural puncture headache.

    Full Text Available A 55-year-old male presented with fever, stupor, aphasia, and left hemiparesis. A history of head trauma 3 months before was also reported. Cranial magnetic resonance imaging revealed slight contrast enhancement of lesions under the right frontal skull plate and right frontal lobe. Because of deterioration in nutritional status and intracranial hypertension, the patient was prepared for burr hole surgery. A subdural empyema (SDE recurred after simple drainage. After detection of Brucella species in SDE, craniotomy combined with antibiotic treatment was undertaken. The patient received antibiotic therapy for 6 months (two doses of 2 g ceftriaxone, two doses of 100 mg doxycycline, and 700 mg rifapentine for 6 months that resulted in complete cure of the infection. Thus, it was speculated that the preexisting subdural hematoma was formed after head trauma, which was followed by a hematogenous infection caused by Brucella species.

    Bone-anchored hearing aids (BAHA) are bone conduction hearing aids commonly implantated by Ear, Nose, and Throat surgeons. We present the first documented case of a subdural hematoma secondary to primary fixation of a BAHA. We present a 65-year-old male patient undergoing a left sided BAHA for bilateral chronic ear infections and difficulty wearing conventional hearing aids. The procedure was uneventful, however, the patient developed a postoperative large acute left temporoparietal intracerebral hematoma associated with an ipsilateral acute subdural hematoma. This required emergency transfer to the local tertiary neurosurgical center for a left decompressive craniotomy and evacuation of the hematoma. The patient required a prolonged stay on an intensive care unit and was eventually discharged to the community for on-going neurological rehabilitation. This is a rare and devastating complication BAHA surgery. Otologist, general ENT surgeons, and neurosurgeons should be aware of this life-threatening complication of BAHA surgery.

    Complication of dental infections might be various and heterogeneous. The most common complications are represented by maxilar celulitis, canine space celulitis, infratemporal space celulitis, temporal celulitis and bacteremia. Among rarest complications we found: sepsis, bacterial endocarditis, mediastinitis, intracranial complications, osteomyelitis, etc. Although dental infections are often considered trivial entities, sometimes they can reach an impressive gravity. In this regard, the present study describes a case of dental infection complicated by meningitis, subdural empiema and cerebral vasculitis. Furthermore, we observed other neurological complications, like thalamic ischemic infarction, during the disease evolution. Noteworthy, these entities were not presented when the patient was admitted to hospital. Therefore, the main aim of this report is to highlight the serious consequences that an infection of dental origin could cause. Key words: Meningitis, subdural empyema, odontogenic infections.

    2009-09-01

    Acute subdural haematoma (ASDH) is one of the conditions most strongly associated with severe brain injury. Reports prior to 1980 describe overall mortality rates for acute subdural haematomas (SDH\\'s) ranging from 40% to 90% with poor outcomes observed in all age groups. Recently, improved results have been reported with rapid diagnosis and surgical treatment. The elderly are predisposed to bleeding due to normal cerebral atrophy related to aging, stretching the bridging veins from the dura. Prognosis in ASDH is associated with age, time from injury to treatment, presence of pupillary abnormalities, Glasgow Coma Score (GCS) or motor score on admission, immediate coma or lucid interval, computerized tomography findings (haematoma volume, degree of midline shift, associated intradural lesion, compression of basal cisterns), post-operative intracranial pressure and type of surgery. Advancing age is known to be a determinant of outcome in head injury. We present the results of a retrospective study carried out in Beaumont Hospital, Dublin, Ireland\\'s national neurosurgical centre. The aim of our study was to examine the impact of age on outcome in patients with ASDH following severe head injury. Only cases with acute subdural haematoma requiring surgical evacuation were recruited. Mortality was significantly higher in older patients (50% above 70 years, 25.6% between 40 and 70 years and 26% below 40 years). Overall poor outcome (defined as Glasgow outcome scores 3-5) was also higher in older patients; 74.1% above 70 years, 48% between 40 and 70 years and 30% below 40 years. Poor outcome in traumatic acute subdural haematoma is higher in elderly patients even after surgical intervention.

  2. A STUDY ON MANAGEMENT OF CHRONIC SUBDURAL HAEMATOMA- BURR HOLE EVACUATION AND MINI CRANIOTOMY

    Full Text Available BACKGROUND Chronic SDH is one of the common neurosurgical conditions requiring surgical treatment. The incidence of chronic SDH is 1.7- 18 per 1,00,000 population. The incidence is higher in the elderly patients, i.e. 58 per 1,00,000. Various treatment modalities available for the treatment of chronic SDH indicate that there is no gold standard for the treatment of chronic SDH. Recurrence is the major problem following treatment and can be as high as 30%. Mini craniotomy is one of the surgical options that can offer better view of the subdural space and may allow us to efficiently clear the loculations and haematoma fluid and thereby decreasing the incidence of recurrences and the need for reoperations. Small craniotomies have not been studied well in the literature except for a few publications. In this study, we are comparing mini craniotomy and burr hole evacuation for the treatment of chronic SDH. MATERIALS AND METHODS All the patients with chronic subdural haematoma operated between August 2013 and January 2016. Patients with recurrent SDH on the same side and patients who underwent different procedures on either side (in case of bilateral haematomas were excluded from the study. The patients were operated by two senior surgeons with one surgeon doing burr hole evacuation and another doing mini craniotomy. Preoperative status and postoperative status was analysed. RESULTS All the patients were analysed both preoperatively and postoperatively. In both the groups, most of the patients shown improvement following surgery, but recurrences are more in burr hole group when compared to mini craniotomy. CONCLUSION Mini craniotomy allows better view of the subdural space and better evacuation of chronic subdural haematoma. Cure rate is higher with mini craniotomy compared to burr hole evacuation.

    A subdural haematoma is described in which a definite computed tomographic (CT) scan diagnosis was made only after contrast enhancement had been achieved by the inhalation of xenon. The different types of enhancement obtained with iodide containing contrast media and with xenon are discussed. The use of xenon to obtain further information in conditions which are inadequately elucidated by conventional CT must be balanced against its anaesthetic effects and relatively high cost.

    A case report. To report a rare complication associated with lumbar decompression surgery. Decompression surgery for lumbar degenerative canal stenosis is one of the most commonly performed spinal procedures. A dural tear is a common troublesome complication of the surgery. Occasionally, dural tear can lead to cerebrospinal fluid (CSF) fistula. However, there is no report of a CSF fistula between the subdural space and a facet joint. A 79-year-old woman underwent lumbar decompression surgery at L3-L5 level. During the surgery, a minimal dural tear was detected although the arachnoid membrane was intact. Because of the absence of CSF leakage and small size of the torn area, repair was not performed. After surgery, she complained of intermittent left buttock pain after ambulation. Her magnetic resonance imaging showed enlarged subdural space and tethering of the dura at L3-L4. CSF aspiration from subdural space was conducted during myelography. However, pain relief was only temporary. CSF fistula between subdural space and facet joint was detected on computed tomographic myelography (CTM). She subsequently underwent second surgery. After separation of the adhesion between the dural tear and the facet joint, CSF leakage was observed. Water-tight sutures, free fat graft, and fibrin glue were applied for repair. She demonstrated complete resolution of her preoperative symptoms at 1 year after surgery. Follow-up magnetic resonance imaging showed no recurrence of the fistula and an adequately decompressed lumbar canal. Computed tomographic myelography was essential to diagnose the rare complication after dural tear. Even in cases of minimal dural tears without arachnoid tear, we suggest repair in order to prevent the rare case of fistula formation.

    A 9-year-old boy had been diagnosed at the age of 9 months as having a cerebellar medulloblastoma and had received 40 Gy of radiation therapy to the brain after removal of the tumor. Cerebral angiography at the time of initial diagnosis did not show any evidence of occlusive disease involving the internal carotid circulation. At the age of 6 years, the patient developed generalized seizures. On examination, he was drowsy and had right hemiparesis. CT scan demonstrated a low-density area in the left frontal lobe. Cerebral angiography showed a marked narrowing of the bilateral internal carotid arteries with moyamoya vessels. The patient was treated medically with aspirin (100 mg/day) and anticonvulsants. His neurological deficits improved gradually. At the age of 8 years, there was no recurrence of the tumor although a slight left subdural hematoma was seen on CT scan. On August 10, 1993, at the age of 9 years, he was admitted for treatment of a developing subdural hematoma. MRI showed a chronic subdural hematoma with thick outer and inner membranes. Cerebral angiography showed occlusion of the left internal carotid artery which fed the right frontal lobe through moyamoya vessels, marked narrowing of the right internal carotid artery distal to the ophthalmic artery, moyamoya vessels at the base, and cortical revascularization througth the ophthalmic, posterior cerebral and middle meningeal arteries. Trepanation and aspiration of the hematoma were performed. The outer membrane of the hematoma was about 2 mm thick and the hematoma cavity was filled with a partially organized hematoma. In this case, we speculate that development of the chronic subdural hematoma involved the following factors: (1) transdural external-internal carotid anastomosis after radiation-induced cerebrovasculopathy; (2) repeated mild head trauma due to gait disturbance after removal of the cerebellar tumor; and (3) administration of acetylsalicylic acid.

    A 73-year-old woman was admitted to hospital due to anaemia. She suffered a minor head trauma and deteriorated to deep unconsciousness. A CT revealed an acute subdural haematoma (ASDH). Initially, she was not found to be a candidate for neurosurgical intervention, but within 24 hours her level of consciousness improved dramatically, and a renewed CT showed resolution of the ASDH. She underwent acute craniotomy with good outcome. This illustrates the importance of re-evaluation of patients with intracranial haemorrhage.

    Full Text Available Background: Subdural hematoma (SDH is a common disease entity treated by neurosurgical intervention. Although the incidence increases in the elderly population, there is a paucity of studies examining their surgical outcomes. Objectives: To determine the neurological and functional outcomes of patients over 70 years of age undergoing surgical decompression for subdural hematoma. Materials and Methods: We retrospectively reviewed data on 45 patients above 70 years who underwent craniotomy or burr holes for acute, chronic or mixed subdural hematomas. We analyzed both neurological and functional status before and after surgery. Results: Forty-five patients 70 years of age or older were treated in our department during the study period. There was a significant improvement in the neurological status of patients from admission to follow up as assessed using the Markwalder grading scale (1.98 vs. 1.39; P =0.005, yet no improvement in functional outcome was observed as assessed by Glasgow Outcome Score. Forty-one patients were admitted from home, however only 20 patients (44% were discharged home, 16 (36% discharged to nursing home or rehab, 6 (13% to hospice and 3 (7% died in the postoperative period. Neurological function improved in patients who were older, had a worse pre-operative neurological status, were on anticoagulation and had chronic or mixed acute and chronic hematoma. However, no improvement in functional status was observed. Conclusion: Surgical management of SDH in patients over 70 years of age provides significant improvement in neurological status, but does not change functional status.

    Full Text Available Hematological abnormalities including thrombocytopenia are common in patients living with HIV infection. Patients with HIV infection related thrombocytopenia present generally with only minor bleeding problems. But cases of subdural hematoma are very rare. A 61-year-old female with a history of HIV infection of 9 years’ duration presented with a 3-month history of generalized headache associated with visual blurring and anterograde amnesia. There was no history of trauma or fever. She was treated empirically for cerebral toxoplasmosis for 6 weeks without any improvement of the symptoms. One week prior to admission, she developed weakness of the left side of the body. Clinical examination revealed left-sided hemiparesis. Computed tomography scan of the brain showed a 25 mm chronic right frontoparietotemporal subdural hematoma compressing the lateral ventricle with midline shift. There was no appreciable cerebral atrophy. A complete blood count showed leucopenia and thrombocytopenia at 92,000 cells/mm3. Her CD4-positive cell count was 48 cells/mm3 despite receiving combination antiretroviral therapy for 9 years. A complete blood count analysis suggestive of thrombocytopenia should raise suspicion of possibilities of noninfectious focal brain lesions like subdural hematoma amongst HIV infected patients presenting with nonspecific neurological symptoms. This will enable prompt diagnosis and allow early appropriate intervention.

    Mycoplasma hominis is a commensal of the genitourinary tract, which is infrequently associated with urogenital infections. Extra-urogenital infections due to M. hominis are rare. Here, we report an unusual case of M. hominis subdural empyema in a woman occurring shortly after delivery. The patient presented with symptoms suggestive of bacterial meningitis. Spinal imaging revealed a subdural empyema that required neurosurgical intervention. Cultures from intraoperatively obtained biopsies identified M. hominis as the causative pathogen. The patient was treated with oral moxifloxacin for 4 weeks resulting in the resolution of the spinal lesion. The subdural empyema was presumably caused by a contaminated epidural blood patch performed with the patient's own blood during an episode of transient M. hominis bacteremia after delivery. The blood patch was indicated for the treatment of cerebrospinal fluid leakage, which had occurred after epidural anesthesia. Our findings highlight the significance of transient M. hominis bacteremia after delivery and implicate that M. hominis should be considered as a causative agent of extra-genitourinary tract infections particularly during the postpartum period or after genitourinary manipulation.

    2014-01-01

    Introduction To date intracranial complication caused by tooth extractions are extremely rare. In particular parietal subdural empyema of odontogenic origin has not been described. A literature review is presented here to emphasize the extreme rarity of this clinical entity. Case presentation An 18-year-old Caucasian man with a history of dental extraction developed dysarthria, lethargy, purulent rhinorrhea, and fever. A computed tomography scan demonstrated extensive sinusitis involving maxillary sinus, anterior ethmoid and frontal sinus on the left side and a subdural fluid collection in the temporal-parietal site on the same side. He underwent vancomycin, metronidazole and meropenem therapy, and subsequently left maxillary antrostomy, and frontal and maxillary sinuses toilette by an open approach. The last clinical control done after 3 months showed a regression of all symptoms. Conclusions The occurrence of subdural empyema is an uncommon but possible sequela of a complicated tooth extraction. A multidisciplinary approach involving otolaryngologist, neurosurgeons, clinical microbiologist, and neuroradiologist is essential. Antibiotic therapy with surgical approach is the gold standard treatment. PMID:25146384

    Full Text Available Introduction. Otitic complications arise from expansion of the middle ear infection. Subdural empyema is a rare otitic complication, and both retropharyngeal and parapharyngeal abscesses have been described in just a few cases. Case report. A 30-year-old male was, admitted as an emergency case because of breathing difficulties, secretion from the ear, and fever. Clinical examination had shown a purulent, fetid secretion from the ear, swelling on the roof of epipharynx, left tonsil pushed medialy, immobile epiglottis, reduced breathing space. Computed tomography revealed thick hypodense content filling cavity, mastoid entering the posterior cranial fossa, descending down throw the parapharyngeal space to the mesopharynx. On the roof and posterior wall of the epipharynx hypodense collection was also present. Tracheotomy was conducted, and incision of the parapharyngeal and retropharyngeal abscess and radical tympanomastoidectomy were performed. The patient’s state deteriorated on the tenth postoperative day with hemiparesis and consciousness disorder. Magnetic resonance imaging was done. It showed subdural empyema of the left frontoparietal region and next to the falx, so craniotomy and abscess drainage were conducted. Conclusion. Parapharyngeal, retropharyngeal abscess and subdural empyema are rare otitic complications. Adequate antibiotic therapy and radical surgical treatment make possible an outcome with survival.

    Full Text Available Abstract Backgroud Extramedullary hematopoiesis (EMH is defined as the presence of hematopoietic stem cells such as erythroid and myeloid lineage plus megakaryocytes in extramedullary sites like liver, spleen and lymph nodes and is usually associated with either bone marrow or hematological disorders. Mammary EMH is a rare condition either in human and veterinary medicine and can be associated with benign mixed mammary tumors, similarly to that described in this case. Case presentation Hematopoietic stem cells were found in a benign mixed mammary tumor of a 7-year-old female mongrel dog that presents a nodule in the left inguinal mammary gland. The patient did not have any hematological abnormalities. Cytological evaluation demonstrated two distinct cell populations, composed of either epithelial or mesenchymal cells, sometimes associated with a fibrillar acidophilic matrix, apart from megakaryocytes, osteoclasts, metarubricytes, prorubricytes, rubricytes, rubriblasts, promyelocytes, myeloblasts. Histological examination confirmed the presence of an active hematopoietic bone marrow within the bone tissue of a benign mammary mixed tumor. Conclusions EMH is a rare condition described in veterinary medicine that can be associated with mammary mixed tumors. It's detection can be associated with several neoplastic and non-neoplastic mammary lesions, i.e. osteosarcomas, mixed tumors and bone metaplasia.

    Full Text Available OBJECTIVES: The onset of chronic subdural hematoma may be associated with direct or indirect minor injuries to the head or a poorly repaired vascular injury. Endothelial progenitor cells happen to be one of the key factors involved in hemostasis and vascular repair. This study was designed to observe the levels of endothelial progenitor cells, white blood cells, platelets, and other indicators in the peripheral blood of patients diagnosed with chronic subdural hematoma to determine the possible relationship between the endothelial progenitor cells and the occurrence, development, and outcomes of chronic subdural hematoma. METHOD: We enrolled 30 patients with diagnosed chronic subdural hematoma by computer tomography scanning and operating procedure at Tianjin Medical University General Hospital from July 2009 to July 2011. Meanwhile, we collected 30 cases of peripheral blood samples from healthy volunteers over the age of 50. Approximately 2 ml of blood was taken from veins of the elbow to test the peripheral blood routine and coagulation function. The content of endothelial progenitor cells in peripheral blood mononuclear cells was determined by flow cytometry. RESULTS: The level of endothelial progenitor cells in peripheral blood was significantly lower in preoperational patients with chronic subdural hematomas than in controls. There were no significant differences between the two groups regarding the blood routine and coagulation function. However, the levels of circulating endothelial progenitor cells were significantly different between the recurrent group and the non-recurrent group. CONCLUSIONS: The level of circulating endothelial progenitor cells in chronic subdural hematoma patients was significantly lower than the level in healthy controls. Meanwhile, the level of endothelial progenitor cells in recurrent patients was significantly lower than the level in patients without recurrence. Endothelial progenitor cells may be related to the

    The optimal management of persistent hemorrhagic radiation cystitis is ill-defined. Various options are available and include oral agents (ie, sodium pentosan polysulfate), intravenous drugs (ie, WF10), topical agents (ie, formalin), hyperbaric oxygen, and endoscopic procedures (ie, electrical cautery, argon plasma coagulation, laser coagulation). In general, it is best to manage patients conservatively and intervene only when necessary with the option least likely to exacerbate the cystitis. More aggressive measures should be employed only when more conservative approaches fail. Bladder biopsies should be avoided, unless findings suggest a bladder tumor, because they may precipitate a complication.

    Post-tonsillectomy hemorrhage (PTH) is a relatively common and potentially life-threatening complication. The objective of this study was to examine the rate of PTH and identify risk factors. A retrospective cohort study was carried out including all tonsillectomies (430 patients) performed...... at Odense University Hospital (OUH) or Svendborg Hospital (SH), Denmark. PTH occurred in 52 patients (12.1%). Of the 180 patients treated with coblation technique, 41 (22.7%) had PTH. There were no fatal bleeding episodes. Multiple regression analysis resulted in three significant covariates: "Coblation...

  16. Solitary Extramedullary Plasmacytoma of the Maxillary Sinus, Progressing to Smoldering Multiple Myeloma with Multifocal Skeletal Involvement, which Resolved Completely Following Chemotherapy Alone.

    Plasmacytoma is an uncommon malignant tumor originating either from plasma cells located in the bone marrow also known as the solitary bone plasmacytoma, or from plasma cells located outside the bone, for e.g. in mucosal surfaces, referred to as the extramedullary plasmacytoma also called the solitary extramedullary plasmacytoma. Both, solitary as well as extramedullary bone plasmacytomas may, particularly in later stages, be accompanied by other osteolytic bone lesions (multifocal bone involvement) and features such as anemia, hypercalcemia, or renal impairment attributable to and indicative of progression to multiple myeloma. These three distinct disorders together comprise the plasma cell neoplasms and essentially represent a continuum of related disease processes. Extramedullary and solitary bone plasmacytomas of the head and neck region are extremely uncommon, and amongst them plasmacytoma of the maxilla is extremely rare. Such a case is being reported here for its rarity. Also, it was associated with multifocal skeletal involvement, making a correct categorization difficult as well as imperative in order to institute the correct treatment. Radiotherapy is considered to be the treatment of choice of plasmacytoma, with adjuvant chemotherapy for multi focal involvement. Surgery is usually limited to biopsy and excision of any residual disease following radiotherapy. The case presented responded extremely well to chemotherapy alone, with a complete resolution of the maxillary tumor, obviating the need for radiotherapy.

  18. Intracerebral Hemorrhage in Eclampsia

    2008-01-01

    Full Text Available The classical triad of symptoms is a basis for making the diagnosis of eclampsia. Nevertheless, none pregnancy complication fails to differ in clinical manifestations, the uncertainty and ambiguity of maternal and fetal prognosis, and in the direct causes of fatal outcomes. The authors present an account of a case of maternal mortality. A 17-year-old primigravida with a history of arterial hypertension at gestational weeks 31—32 developed a series of seizures and lost consciousness. She was diagnosed as having eclampsia complicated by acute ischemic attack. Emergency cesarean delivery was made. Postoperatively, the puerpera was transferred to the neurosurgery unit to be examined and treated. Computed tomography revealed intracerebral hemorrhage, with blood entering the brain ventricles, and occlusive hydrocephalus from the fourth ventricular level. Ventricular drainage was made as described by Arendt. The prognosis was poor. The patient’s death was stated on postpartum day 5. The authors consider that the publication and discussion of such cases should give a better insight into the development of eclampsia and its life-threatening complications. Fortunately, eclampsia is rare, the incidence of its complications is even less. But each such a case deserves a detailed and thoughtful discussion. Key words: eclampsia, intracerebral hemorrhage.

  19. Management of chronic subdural haematoma: burr hole drainage, replacement with Hartmann's solution, and closed-system drainage.

    1999-12-01

    Although the treatment of chronic subdural haematoma by burr hole drainage has been performed in the past with or without using a closed drainage system, the problem of intracranial air entrapment still persists and can cause a deterioration in the level of consciousness or seizures in the postoperative period. Cerebral infarction may also develop a few days after surgery because of the intracranial hypotension that occurs during the drainage procedure. In an attempt to minimise these complications and to prevent cerebral infarction and its attendant morbidity, we have developed a technique of treating chronic subdural haematoma-namely, performing burr hole drainage, irrigation and replacement of the haematoma with Hartmann's solution, and closed-system drainage of the subdural space with a silicone catheter. The blood pressure is closely monitored and maintained by the infusion of fluids throughout the procedure. An illustrative case using this technique is presented in this paper.

    Acute lymphoblastic leukemia (ALL) is a clonal hematological disease characterized by inadequate normal hematopoiesis secondary to excessive proliferation of leukemic blasts and their impaired differentiation. As a result, patients usually manifest symptoms related to bone marrow failure. It's very uncommon for ALL patients to present with normal hemogram. Herein, we describe two patients who presented with excruciating bone pain at orthopedic clinics. Osteopathy involving multiple bones was noted initially, but acute leukemia was never considered as one of the differential diagnoses because of the completely normal hemogram in both cases. Consequently, the diagnosis of leukemia was slightly delayed. Upon literature review, we found that ALL patients with solely extramedullary diseases and nearly normal hemogram had exclusively pre-B disease. We also propose a putative hypothesis for this interesting finding.

    The authors report a case of a bilateral chronic subdural hematoma with niveau formation and another rare case of an acute subdural hematoma with niveau formation on plain CT. The different mechanisms of the niveau formation in these cases are speculated about. The first case was a 75-year-old male who showed a drowsy state, urinary incontinence, and muscle weakness of the bilateral lower limbs. No definite history of head trauma could be found. A plain CT scan showed a bilateral-crescent type fluid collection with niveau formation, consisting of a low-density area in the upper part and a high-density area in the lower part. An operation showed bilateral, moderately encapsulated subdural hematomas; they were evacuated. The second case was a 61-year-old male with head trauma due to a fall from a ladder. On admission, neurological examination revealed a decerebrate posture, a deep coma, and anisocoria. A plain CT scan twenty hours after the onset showed a crescent-type fluid collection with niveau formation in the left fronto-parietal region. The operation showed an acute subdural hematoma containing xanthochromic fluid and coagulated blood. No capsule of hematoma could be seen. The incidence of niveau formation in chronic subdural hematomas is not low (5 - 20%); such niveau formation is thought to be caused by rebleeding into the hematoma and the spending of considerable time in the supine position. On the other hand, no case of an acute subdural hematoma with niveau formation has previously been reported. With regard to this mechanism of niveau formation, we speculate that the hematoma is mixed with cerebrospinal fluid from the arachnoidal tear caused by the head trauma; also, a considerable time in the supine position is necessary.

    Full Text Available A shift of approach from ′clinics trying to fit physiology′ to the one of ′physiology to clinics′, with interpretation of the clinical phenomena from their physiological bases to the tip of the clinical iceberg, and a management exclusively based on modulation of physiology, is finally surging as the safest and most efficacious philosophy in hemorrhagic shock. ATLS® classification and recommendations on hemorrhagic shock are not helpful because antiphysiological and potentially misleading. Hemorrhagic shock needs to be reclassified in the direction of usefulness and timing of intervention: in particular its assessment and management need to be tailored to physiology.

    The combination of subarachnoid hemorrhage (SAH) and subhyaloid hemorrhage is known as 'Terson syndrome'. Retinal hemorrhage is commonly observed clinically in the optic fundi of patients with SAH, however, subhyaloid hemorrhage of the globe in the setting of SAH has been rarely on CT of the brain. Several mechanisms of subhyaloid hemorrhage have been proposed: a. A sudden increase in intracranial pressure (ICP) forces blood from the subarachnoid space directly into the preretinal space. b. A sudden rise in ICP is thought to decrease venous return to the cavernous sinus from the veins draining the globe. The increased retinal venous pressure results in stasis followed by vessel rupture. c. A sudden rise in ICP obstructs both the retinochoroidal anastomoses and the central retinal vein due to a rapid effusion of CSF through the communication of the subarachnoid space with the optic nerve sheat. This produces an acute decrease in venous drainage from the retina and results in stasis and hemorrhage. A 35 year old man, with a history of a non controlled arterial hypertension, dilated cardiopathy and 'agitation episodes'. He had a spontaneous intracranial hemorrhage, consistent in a parenchymal hematoma ruptured into ventricles and subarachnoid space. The CT showed through optic nerve sheath this hemorrhage extended to subhyaloid space. The patient came in coma 'dépassé' and brain death. We report a case of Terson syndrome demonstrated by CT. This CT allow see the blood from the subarachnoid space erupt directly into the preretinal space through optic nerve sheath, confirming one the proposed mechanism for this syndrome.

    Full Text Available Subdural hematoma (SDH is a rare but serious complication of spinal anesthesia. We report a case of intracranial SDH in a patient developing 11 days after spinal anesthesia for cesarean section. The patient complained of headache on the 2nd post-operative day that was relieved by analgesics, bed rest and hydration. Later she presented with severe headache, vomiting, dizziness, dysarthria, irritability and somnolence. Diagnosis of the left sided SDH was confirmed radiologically and treated surgically. The patient recovered completely. The report highlights the need of considering the possibility of SDH in patients when postdural puncture headache is prolonged or recurs after a headache free period with neurological symptoms.

    Shaken baby syndrome (SBS) is a form of child abuse that can cause significant head injuries, of which subdural hematoma (SDH) is the most common manifestation. We report the MRI findings of chronic SDH in three cases of SBS, involving two-, three- and eight-month-old babies. The SDH signal was mostly low on T1-weighted images and high on T2-weighted images, suggesting chronic SDH. In chronic SDH, a focal high signal on T1-weighted images was also noted, suggesting rebleeding. Contrast-enhanced MRI revealed diffuse dural enhancement.

    Calcified chronic subdural hematomas are an occurrence rarely seen in neurosurgical clinical practice. And when they occur bilaterally, the radiologic image they present is fascinating, as is the clinical presentation, but their management may be challenging. They have been reported to present with a multitude of neurologic deficits but never with diabetes insipidus, which is described here. Due to the rarity of this pathology, the management protocol is not well defined, though there have been quite a few papers on this condition. This review article gathers information published over the years on this rare entity to suggest a treatment protocol. Copyright © 2016 Elsevier Inc. All rights reserved.

    Intracerebral hemorrhage and, more specifically, intraparenchymal hemorrhage, are devastating disease processes with poor clinical outcomes. Primary injury to the brain results from initial hematoma expansion while secondary hemorrhagic injury occurs from blood-derived products such as hemoglobin, heme, iron, and coagulation factors that overwhelm the brains natural defenses. Novel neuroprotective treatments have emerged that target primary and secondary mechanisms of injury. Nonetheless, translational application of neuroprotectants from preclinical to clinical studies has yet to show beneficial clinical outcomes. This review summarizes therapeutic agents and neuroprotectants in ongoing clinical trials aimed at targeting primary and secondary mechanisms of injury after intraparenchymal hemorrhage. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available In this case report, we discussed a case of spontaneous intracapsular tonsillar haemorrhage appearing as a tumor medial to the left palatine tonsil and clinging to the tonsillar tissue with a pedicle. The patient was a 30 years old healthy pregnant woman. She had a growing sensation of a lump in her oropharynx and dysphagia in the past three months. She had no history of acute and chronic tonsillitis or trauma. On examination, a mobile brown mass with a 2 cm diameter having a small pedicle at the upper pole of the left palatine tonsil was seen. Other laboratory results were normal. The mass was excised under general anesthesia. Histological evaluation revealed tonsillar intracapsular bleeding with lymphoepi-thelial tissue and acute hemorrhagic fields bounded by a capsule. A postpartum tonsillectomy was planned for our patient. Tonsillectomy must be performed to patients followed up with this diagnosis in order to differentiate between dyspha-gia, risks of bleeding and aspiration, and malignant tumors.

    Chronic low back pain is extremely common with a life time prevalence estimated at greater than 70%. Facet joint arthrosis is thought to be the causative aetiological substrate in approximately 25% of chronic low back pain cases. Facet joint injection is a routine intervention in the armamentarium for both the diagnostic and therapeutic management of chronic low back pain. In fact, a study by Carrino et al. reported in excess of 94,000 facet joint injection procedures were carried out in the US in 1999. Although generally considered safe, the procedure is not entirely without risk. Complications including bleeding, infection, exacerbation of pain, dural puncture headache, and pneumothorax have been described. We report a rare case of a 47-year-old female patient who developed a left L4/5 facet septic arthrosis with an associated subdural empyema and meningitis following facet joint injection. This case is unique, as to the best of our knowledge no other case of subdural empyema following facet joint injection has been reported in the literature. Furthermore this case serves to highlight the potential serious adverse sequelae of a routine and apparently innocuous intervention. The need for medical practitioners to be alert to and respond rapidly to the infective complications of facet joint injection cannot be understated. Copyright © 2016 Polish Neurological Society.

    Little experience exists in the application of source reconstruction methods to recordings from subdural strip and grid electrodes. This study addressed the question, whether reliable and accurate 3D source localization is possible from the Electrocorticogram (ECoG). The accuracy of source reconstruction was investigated by simulations and a case study. Simulated sources were used to compute potentials at the electrode positions derived from the MRI of a patient with subdural electrodes. Used procedures were the linear estimation (minimum norm) algorithm and the MUSIC (MUltiple SIgnal Classification) scan. Maxima of linear estimation were attracted to adjacent electrodes. Reliable localization with a localization error 15 mm was only achieved for about 35% of the original source positions. Maxima of the MUSIC metric were identical to original positions for simulations without noise. Noise reduced the percentage of reliable solutions down to a 79.0%. Electrode contacts distant to the source had small influence on localization accuracy. The case study supported simulation results. Reliable source reconstruction derived from ECoG can be achieved by the application of the MUSIC algorithm. Linear estimation needs additional compensation mechanisms. MUSIC based 3D localization based on ECoG has the potential improving epilepsy diagnosis and cognitive research.

    The patient, a 19-year-old male, began suffering from severe headache, vomiting, and high fever. Two days later the patient was admitted in a semicomatose state and with left hemiplegia. Nuchal rigidity and choked disc were not noticed. WBC count was 12,500/mm/sup 3/. CT scan disclosed marked swelling of the right cerebral hemisphere with midline shift. Except for a small lucent space in the parafalcial region, no extracerebral collection was noted in either pre- or post-contrast scans. Plain craniograms showed clouding of the left frontal, ethmoidal, and sphenoidal sinuses. Carotid angiography revealed prolongation of the circulation time and stenosis of the supraclinoidal portion of the right carotid artery. Right fronto-parietal decompressive craniectomy was performed. Subdural empyema was found and evacuated. Curettage and drainage of the empyema in the paranasal sinuses were also done. A bone defect 4 mm in diameter was detected on the medial-upper wall of the left frontal sinus. The causative organism was confirmed as ..cap alpha..-Streptococcus. Both systemic and local antibiotics were administered and the patient recovered well and was discharged without any neurological deficit. The authors emphasized that cerebral angiography is necessary for its accurate diagnosis of subdural empyema in its acute stage and that emergency intracranial and rhino-otological operations should be concomitantly performed.

    2011-09-01

    We aimed to identify the incidence, clinical features, management, and outcome of subdural hematomas (SHs) in infancy and childhood. Twenty-one children younger than 11 years with SH were analyzed. Clinical features and possible child abuse were considered in each case. Eight children experienced minor injuries due to hitting of solid items on their head. Five of these children also had coagulation disorders. Three of the children suffered from child abuse, only one of the children had head trauma due to car accident. Nine of the patients experienced SH due to fall down. Nine patients have acute SH, 7 had subacute SH, 4 had chronic SH, and 1 had acute and subacute SH together. Clinical presentation varied greatly. Most of them presented with vomiting and seizure. The outcome patterns were different among the patients. Deep coma on admission was associated with an unfavorable outcome. Subdural hematoma is common in infancy and childhood and carries a poor prognosis. Most of the cases are due to head trauma, coagulation disorders, and child abuse. We believe that clinical investigation of such children should be carried out in a multidisciplinary approach with the collaboration of pediatricians, social workers, and neurosurgeons.

    The authors report the case of a 45-year-old woman who presented to our institution with 10 days history of confusion and signs of progressive raised intracranial pressure as a result of a minor head injury occurred 4 weeks before. A brain CT-scan showed a large right hemispheric chronic subdural haematoma which was, as routinely, treated by burr-hole craniostomy and closed-drainage. Although the procedure was uneventful, the next day the patient developed a mild left hemiparesis associated to a slight global status worsening. A brain CT scan showed an intracerebral position of the drain with diffuse brain oedema and midline shift. Following drain removal the patient developed a serious neurological deterioration dropping the Glasgow coma scale to 8/15 as the result of an intracerebral and intraventricular haemorrhage along the removed drain trajectory. The clinical features of this iatrogenic complication are reported analysing also globally chronic subdural haematoma management and discussing pertinent literature. PMID:22669031

    Sharpe, Abigail N.; Jackson, Andrew

    2014-02-01

    Objective. Electrical stimulation of the spinal cord has potential applications following spinal cord injury for reanimating paralysed limbs and promoting neuroplastic changes that may facilitate motor rehabilitation. Here we systematically compare the efficacy, selectivity and frequency-dependence of different stimulation methods in the cervical enlargement of anaesthetized monkeys. Approach. Stimulating electrodes were positioned at multiple epidural and subdural sites on both dorsal and ventral surfaces, as well as at different depths within the spinal cord. Motor responses were recorded from arm, forearm and hand muscles. Main results. Stimulation efficacy increased from dorsal to ventral stimulation sites, with the exception of ventral epidural electrodes which had the highest recruitment thresholds. Compared to epidural and intraspinal methods, responses to subdural stimulation were more selective but also more similar between adjacent sites. Trains of stimuli delivered to ventral sites elicited consistent responses at all frequencies whereas from dorsal sites we observed a mixture of short-latency facilitation and long-latency suppression. Finally, paired stimuli delivered to dorsal surface and intraspinal sites exhibited symmetric facilitatory interactions at interstimulus intervals between 2-5 ms whereas on the ventral side interactions tended to be suppressive for near-simultaneous stimuli. Significance. We interpret these results in the context of differential activation of afferent and efferent roots and intraspinal circuit elements. In particular, we propose that distinct direct and indirect actions of spinal cord stimulation on motoneurons may be advantageous for different applications, and this should be taken into consideration when designing neuroprostheses for upper-limb function.

    The median nerve N20 and P22 SEP components constitute the initial response of the primary somatosensory cortex to somatosensory stimulation of the upper extremity. Knowledge of the underlying generators is important both for basic understanding of the initial sequence of cortical activation and to identify landmarks for eloquent areas to spare in resection planning of cortex in epilepsy surgery. We now set out to localize the N20 and P22 using subdural grid recording with special emphasis on the question of the origin of P22: Brodmann area 4 versus area 1. Electroencephalographic dipole source analysis of the N20 and P22 responses obtained from subdural grids over the primary somatosensory cortex after median nerve stimulation was performed in four patients undergoing epilepsy surgery. Based on anatomical landmarks, equivalent current dipoles of N20 and P22 were localized posterior to (n = 2) or on the central sulcus (n = 2). In three patients, the P22 dipole was located posterior to the N20 dipole, whereas in one patient, the P22 dipole was located on the same coordinate in anterior-posterior direction. On average, P22 sources were found to be 6.6 mm posterior [and 1 mm more superficial] compared with the N20 sources. These data strongly suggest a postcentral origin of the P22 SEP component in Brodmann area 1 and render a major precentral contribution to the earliest stages of processing from the primary motor cortex less likely.

  1. Evolution and Prospects for Intracranial Pharmacotherapy for Refractory Epilepsies: The Subdural Hybrid Neuroprosthesis

    Full Text Available Intracranial pharmacotherapy is a novel strategy to treat drug refractory, localization-related epilepsies not amenable to resective surgery. The common feature of the method is the use of some type of antiepileptic drug (AED delivery device placed inside the cranium to prevent or stop focal seizures. This distinguishes it from other nonconventional methods, such as intrathecal pharmacotherapy, electrical neurostimulation, gene therapy, cell transplantation, and local cooling. AED-delivery systems comprise drug releasing polymers and neuroprosthetic devices that can deliver AEDs into the brain via intraparenchymal, ventricular, or transmeningeal routes. One such device is the subdural Hybrid Neuroprosthesis (HNP, designed to deliver AEDs, such as muscimol, into the subdural/subarachnoid space overlaying neocortical epileptogenic zones, with electrophysiological feedback from the treated tissue. The idea of intracranial pharmacotherapy and HNP treatment for epilepsy originated from multiple sources, including the advent of implanted medical devices, safety data for intracranial electrodes and catheters, evidence for the seizure-controlling efficacy of intracerebral AEDs, and further understanding of the pathophysiology of focal epilepsy. Successful introduction of intracranial pharmacotherapy into clinical practice depends on how the intertwined scientific, engineering, clinical, neurosurgical and regulatory challenges will be met to produce an effective and commercially viable device.

    Full Text Available The development of acute supratentorial interhemispheric subdural hematomas is an uncommon yet a highly distinct event because of their unusual location, unknown natural history, and debated management. The majority develop in patients with head trauma, generalized bleeding tendency, or coagulopathy. We report on 3 patients who developed spontaneous acute inter-hemispheric subdural hematomas. They were 72, 66, and 65 years old, respectively. Two were males and the 3rd was a female. There was no head trauma, bleeding tendency, or coagulopathy. Two of them were hypertensive but none of them was diabetic, epileptic, or alcoholic. Two patients died, on day 1 and 2 respectively, and the 3rd patient was discharged by his next of kin after 3 hours of admission to our Acute and Emergency department. No neurosurgical intervention was carries out and all patients were treated conservatively. The hematoma was fronto-occipital and was located on the left side in 2 patients while in the 3rd patient it was a right-sided parieto-occipital one. Although the initial investigations had pointed out to the spontaneous development of those hematomas in our patients, a further search for an underlying etiology was supposed to be done, but the early death of 2 patients and the premature discharge of the 3rd patient had intersected with this work-up. The rapid deterioration and death of 2 patients might have been prevented if an early evacuation was done.

    In presurgical investigations of refractory frontal lobe epilepsy, subdural EEG recordings offer extensive cortical coverage, but may overlook deep sources. Electrical Source Localization (ESL) from subdural recordings could overcome this sampling limitation. This study aims to assess the clinical relevance of this new method in refractory frontal lobe epilepsy associated with focal cortical dysplasia. In 14 consecutive patients, we retrospectively compared: (i) the ESL of interictal spikes to the conventional irritative and seizure onset zones; (ii) the surgical outcome of cases with congruent ESL and resection volume to cases with incongruent ESL and resection volume. Each spike type was averaged to serve as a template for ESL by the MUSIC and sLORETA algorithms. Results were superimposed on the corresponding pre and post-surgical MRI. Both ESL methods were congruent and consistent with conventional electroclinical analysis in all patients. In 7 cases, ESL identified a common deep source for spikes of different 2D localizations. The inclusion of ESL in the resection volume correlated with seizure freedom. ESL from subdural recordings provided clinically relevant results in patients with refractory frontal lobe epilepsy. ESL complements the conventional analysis of subdural recordings. Its potential in improving tailored resections and surgical outcomes should be prospectively assessed.

    Full Text Available Tuberculous brain abscess and subdural empyema are extremely rare manifestations of central nervous system tuberculosis. Here, we report a case of an 11-year-old immunocompetent child who developed temporal lobe abscess and subdural empyema following chronic otitis media. A right temporal craniotomy was performed and the abscess was excised. The Ziehl Nielsen staining of the aspirated pus from the temporal lobe abscess yielded acid fast bacilli. Prompt administration of antituberculous treatment resulted in complete recovery of the child. Even though the subdural abscess was not drained, we presume that to be of tubercular aetiology. Ours is probably the first case of brain abscess and subdural empyema due to Mycobacterium tuberculosis reported in the same child. This case is being reported because of its rarity and to stress the importance of routine staining for tubercle bacilli in all cases of brain abscess, especially in endemic areas, as it is difficult to differentiate tuberculous from pyogenic abscess clinically as well as histopathologically.

    Background: To review MR appearances of ovarian hemorrhage, and to describe its characteristic imaging findings. Methods: 12 women (age range, 20-44, mean, 26 years) with suspected ovarian hemorrhage underwent pelvic MR examinations. We retrospectively reviewed MR findings regarding signal intensities, localization, and wall enhancement of adnexal masses, and signal intensities of ascites. Results: Adnexal masses were detected in all cases. In eight cases, adnexal mass exhibited intermediate signal intensity on T1WI, and intermediate to low signal intensity on T2WI. In other case, adnexal mass exhibited marked hyperintensity on T1WI. In the remaining three cases, cystic mass with low signal intensity on T1WI and high signal intensity on T2WI was noted. Ascites was present in all cases, and showed intermediate signal on T1WI and intermediate to low signal on T2WI. Conclusions: In ovarian hemorrhage, hemorrhagic ascites and adnexal mass was visualized with specific MR signal intensity. Due to its sensitivity for identifying blood, MR imaging is useful in the diagnosis of ovarian hemorrhage, especially when ultrasonography findings are not definitive.

    We retrospectively analyzed the clinical and imaging characteristics, diagnosis, and treatment outcomes of 10 patients with hemorrhagic cerebral paragonimiasis (CP), and we evaluated the influence of Paragonimus infection on cerebrovascular damage. Ten patients (7 male and 3 female; median age 15.7 years, range 4-46 years) with hemorrhagic CP were diagnosed between April 2009 and January 2013. All patients underwent the head computed tomography scans and 9 patients underwent MRI examinations. Four patients underwent computed tomographic angiography, magnetic resonance angiography, and digital subtraction angiography. Liquid-based cytological examination of cerebrospinal fluid was performed in 7 patients. Follow-up examinations were performed for 9 cases for a period of 12 to 62 months. Hemorrhagic CP accounted for 37% of CP cases (10/27). No patients were initially diagnosed with CP. The major symptoms of hemorrhagic CP included acute headache, vomiting, hemiparalysis, epilepsy, blurred vision, sensory impairment, and tinnitus. Four cases were surgically treated. Most symptoms markedly improved, but fine motor dysfunction and mental dysfunction remained in 3 surgical patients. Hemorrhagic stroke typically occurred during the acute stage and in the early stages of further Paragonimus migration. Delay of treatment increased the risk of initial and recurrent stroke. © 2014 American Heart Association, Inc.

    Objective. Restoring or replacing function in paralyzed individuals will one day be achieved through the use of brain-machine interfaces. Regaining hand function is a major goal for paralyzed patients. Two competing prerequisites for the widespread adoption of any hand neuroprosthesis are accurate control over the fine details of movement, and minimized invasiveness. Here, we explore the interplay between these two goals by comparing our ability to decode hand movements with subdural and epidural field potentials (EFPs). Approach. We measured the accuracy of decoding continuous hand and finger kinematics during naturalistic grasping motions in five human subjects. We recorded subdural surface potentials (electrocorticography; ECoG) as well as with EFPs, with both standard- and high-resolution electrode arrays. Main results. In all five subjects, decoding of continuous kinematics significantly exceeded chance, using either EGoG or EFPs. ECoG decoding accuracy compared favorably with prior investigations of grasp kinematics (mean ± SD grasp aperture variance accounted for was 0.54 ± 0.05 across all subjects, 0.75 ± 0.09 for the best subject). In general, EFP decoding performed comparably to ECoG decoding. The 7-20 Hz and 70-115 Hz spectral bands contained the most information about grasp kinematics, with the 70-115 Hz band containing greater information about more subtle movements. Higher-resolution recording arrays provided clearly superior performance compared to standard-resolution arrays. Significance. To approach the fine motor control achieved by an intact brain-body system, it will be necessary to execute motor intent on a continuous basis with high accuracy. The current results demonstrate that this level of accuracy might be achievable not just with ECoG, but with EFPs as well. Epidural placement of electrodes is less invasive, and therefore may incur less risk of encephalitis or stroke than subdural placement of electrodes. Accurately decoding motor

    Paediatric subdural empyema is frequently seen in developing Asean countries secondary to rinosinusogenic origins. A cross-sectional analysis on the surgical treatment of intracranial subdural empyema in Hospital Kuala Lumpur (HKL), a major referral center, was done in 2004. A total number of 44 children who fulfilled the inclusion criteria were included into this study. The methods of first surgery, volume of empyema on contrasted CT brain, improvement of neurological status, re-surgery, mortality and morbidity, as well as the demographic data such as age, gender, sex, duration of illness, clinical presentation, probable origin of empyema, cultures and follow-up were studied. Chi-square test was performed to determine the association between surgical methods and the survival of the patients, neurological improvement, clearance of empyema on CT brain, re-surgery and long morbidity among the survivors. If the 20% or more of the cells were having expected frequency less than five, then Fisher's Exact test was applied. The level of significance was set at 0.05. SPSS version 12.0 was used for data entry and data analysis. There were 44 patients who were less than 18 years. Their mean age was 5.90 ± 6.01 years. There were 30 males (68.2%) and 14 females (31.8%) involved in the study. Malays were majority with 28 (63.6%) followed by Indian 8 (18.2%), Chinese 5 (11.4%) and others 3 (6.8%). The variables which were under interest were gender, race, headache, vomiting, seizures, sign of meningism, cranial nerve palsy, thickness site of abscess, first surgical treatment, improvement in neurological deficit, clearance of CT and whether re-surgery was necessary. All variables were found not to be associated with Henk W Mauser Score for PISDE grading. Comparison between this urban study and a rural setting study by the same corresponding author in the same period on subdural empyema was done. Common parameters were compared and it was found out that seizures were more

    Full Text Available This retrospective study was to determine if patient-specific instrumentation (PSI for total knee arthroplasty (TKA leads to shortened surgical time through increased operating room efficiency according to different tibial PSI designs. 166 patients underwent primary TKA and were categorized into three groups as follows: PSI without extramedullary (EM tibial guide (group 1, n=48, PSI with EM tibial guide (group 2, n=68, and conventional instrumentation (CI group (group 3, n=50. Four factors were compared between groups, namely, operative room time, thickness of bone resection, tibial slope, and rotation of the component. The mean surgical time was significantly shorter in the PSI with EM tibial guide group (group 2, 63.9±13.6 min compared to the CI group (group 3, 82.8±24.9 min (P<0.001. However, there was no significant difference in the PSI without EM tibial guide group (group 1, 75.3±18.8 min. This study suggests that PSI incorporating an EM tibial guide may lead to high operative efficiency in TKA compared to CI. This trial is registered with KCT0002384.

    Most of Tarlov or perineurial cysts remain asymptomatic throughout the patient's life. The pathogenesis is still unclear. Hemorrhage has been suggested as one of the possible causes and trauma with resultant hemorrhage into subarachnoid space has been suggested as an origin of these cysts. However, Tarlov cysts related to spontaneous subarachnoid hemorrhage has not been reported. The authors report a case of Tarlov cyst which was symptomatic following spontaneous subarachnoid hemorrhage.

    Full Text Available The protein S-100B is a biomarker increasingly used within neurosurgery and neurointensive care. As a relatively sensitive, yet unspecific, indicator of CNS pathology, potential sources of error must be clearly understood when interpreting serum S-100B levels. This case report studied the course of a 46-year-old gentleman with a chronic subdural haemorrhage, serum S-100B levels of 22 μg/L and a history of malignant melanoma. Both intra- and extra-cranial sources of S-100B are evaluated and imply an unclear contribution of several sources to the total serum concentration. Potential sources of error when interpreting serum concentrations of S-100B are discussed

    Full Text Available Electroconvulsive therapy (ECT is commonly used in the management of medication nonresponsive depressive disorder, with proven efficacy in psychiatric practice since many decades. A rare complication of intracranial bleed following this therapeutic procedure has been reported in sporadic case reports in the English literature. We report a case of such a complication in a 42-year-old male, a known case of nonorganic medication nonresponsive depressive disorder for the last two years who required ECT application. Presenting symptoms included altered mental state, urinary incontinence, and repeated episodes of vomiting; following ECT procedure with magnetic resonance imaging (MRI of the brain suggestive of bilateral acute subdural hematoma. Despite the view that it may be used in neurological conditions without raised intracranial tension, it will be worthwhile to be vigilant during post-ECT recovery for any emergent complications.

    Aquaporin 1 (AQP1) is a molecular water channel expressed in many anatomical locations, particularly in epithelial barriers specialized in water transport. The aim of this study was to investigate AQP1 expression in chronic subdural hematoma (CSDH) membranes. In this preliminary study, 11 patients with CSDH underwent burr hole craniectomy and drainage. Membrane specimens were stained with a monoclonal antibody targeting AQP1 for immunohistochemical analysis. The endothelial cells of the sinusoid capillaries of the outer membranes exhibited an elevated immunoreactivity to AQP1 antibody compared to the staining intensity of specimens from the inner membrane and normal dura. These findings suggest that the outer membrane might be the source of the increased fluid accumulation responsible for chronic hematoma enlargement.

    To determine copeptin levels in patients with suspected intracranial events and to determine whether copeptin levels could be used in the discrimination of cerebral infarction, intracranial hemorrhage, and subarachnoid hemorrhage in the emergency room. Blood samples were obtained from the patients prior to imaging to determine the levels of copeptin. Patients were divided into diagnostic groups after the imaging. One hundred and seventy-six participants, who were enrolled in the study, were as follows: 50 cerebral infarction (CI) patients (M/F: 24/26), 47 intracranial hemorrhage (ICH) patients (M/F: 27/20), 29 subarachnoid hemorrhage (SAH) patients (M/F: 17/12) and 50 healthy controls. Differences and correlations between groups were analyzed. Plasma levels of copeptin in patients with CI, ICH, and SAH were 5.49 ng/dL (IQR 4.73 to 6.96), 4.50 ng/dL (IQR 3.04 to 9.77), and 5.90 ng/dL (IQR 3.11 to 13.26), respectively. It was found to be 2.0 ng/dL (IQR 1.57 to 2.5) in healthy volunteers. There was no significant correlation between copeptin levels and Intracerebral Hemorrhage Score (ICHS) (r = 0.231, p = 0.118). However, significant positive correlation was found between copeptin levels with the National Institutes of Health Stroke Scale (NIHSS) (r = 0.365, p = 0.009) and the BotterelHunt and Hess Scale (BHHS) (r = 0.590, p = 0.001). The copeptin levels of 41 (32.5%) patients who died were found to be significantly higher than those 85 (67.5%) patients who were discharged (p Copeptin levels in patients with CI, ICH, and SAH are significantly higher than healthy volunteers, but the plasma level of copeptin is not decisive in the discrimination of CI, ICH, and SAH.

  1. Analysis of Epileptic Discharges from Implanted Subdural Electrodes in Patients with Sturge-Weber Syndrome.

    Yasushi Iimura

    Full Text Available Almost two-thirds of patients with Sturge-Weber syndrome (SWS have epilepsy, and half of them require surgery for it. However, it is well known that scalp electroencephalography (EEG does not demonstrate unequivocal epileptic discharges in patients with SWS. Therefore, we analyzed interictal and ictal discharges from intracranial subdural EEG recordings in patients treated surgically for SWS to elucidate epileptogenicity in this disorder.Five intractable epileptic patients with SWS who were implanted with subdural electrodes for presurgical evaluation were enrolled in this study. We examined the following seizure parameters: seizure onset zone (SOZ, propagation speed of seizure discharges, and seizure duration by visual inspection. Additionally, power spectrogram analysis on some frequency bands at SOZ was performed from 60 s before the visually detected seizure onset using the EEG Complex Demodulation Method (CDM.We obtained 21 seizures from five patients for evaluation, and all seizures initiated from the cortex under the leptomeningeal angioma. Most of the patients presented with motionless staring and respiratory distress as seizure symptoms. The average seizure propagation speed and duration were 3.1 ± 3.6 cm/min and 19.4 ± 33.6 min, respectively. Significant power spectrogram changes at the SOZ were detected at 10-30 Hz from 15 s before seizure onset, and at 30-80 Hz from 5 s before seizure onset.In patients with SWS, seizures initiate from the cortex under the leptomeningeal angioma, and seizure propagation is slow and persists for a longer period. CDM indicated beta to low gamma-ranged seizure discharges starting from shortly before the visually detected seizure onset. Our ECoG findings indicate that ischemia is a principal mechanism underlying ictogenesis and epileptogenesis in SWS.

    Recurrent chronic subdural hematoma (CSDH) is not rare. Some studies have demonstrated the role of dexamethasone in the medical management of chronic subdural hematoma. However, no systematic study in the treatment of recurrent CSDH has been published. The aim of our study is to evaluate the efficacy and safety of dexamethasone in patients with recurrent CSDH. We retrospectively reviewed medical records of consecutive patients from July 2010 to September 2014. A total of 27 patients with symptomatic recurrent CSDH were included in the analysis. Follow-up for each patient consisted of computed tomography or magnetic resonance imaging every 28 days from admission to the resolution of hematoma. Data were collected on hematoma volume, complications, and outcome. Among the 27 patients, 3 patients with recurrent CSDH were only treated by burr hole surgery. Of the other 24 patients who primarily underwent dexamethasone treatment, 17 (70.8%) patients were treated successfully with medical treatment, whereas 7 patients required reoperation. Complications were noted in 3 (12.5%) patients (1 hyperglycemia, 1 urinary tract infection, and 1 pneumonia). There was 1 mortality (4.2%) for massive brain infarction. Twenty-one of the 24 patients (87.5%) recovered to their previous functional levels. There was no statistical significance in Fisher text between surgery and dexamethasone regarding success, complication, and functional recovery rate. Patients with recurrent CSDH can be treated successfully and safely with the nonsurgical medical treatment of dexamethasone. By use of this method, reoperation may be avoided.

    Object Cerebral cortex electrophysiology is poorly sampled using standard, low spatial resolution clinical intracranial electrodes. Adding microelectrode arrays to the standard clinical macroelectrode arrays increases the spatial resolution and may ultimately improve the clinical utility of intracranial electroencephalography (iEEG). However, the safety of hybrid electrode systems containing standard clinical macroelectrode and microelectrode arrays is not yet known. The authors report on their preliminary experience in 24 patients who underwent implantation of hybrid electrodes. Methods In this study, 24 consecutive patients underwent long-term iEEG monitoring with implanted hybrid depth and subdural grid and strip electrodes; both clinical macroelectrodes and research microelectrodes were used. The patients included 18 women and 6 men with an average age of 35 ± 12 years (range 21–65). The mean hospital stay was 11 ± 4 days (range 5–20), with mean duration of implantation 7.0 ± 3.2 days (range 3–15). Data from the 198 consecutive craniotomies for standard clinical subdural grid insertion (prior to surgery in the 24 patients described here) were used for comparison to investigate the relative risk of complications. Results Focal seizure identification and subsequent resection was performed in 20 patients. One patient underwent a subsequent operation after neurological deterioration secondary to cerebral swelling and a 5-mm subdural hematoma. There were no infections. The overall complication rate was 4.2% (only 1 patient had a complication), which did not significantly differ from the complication rate previously reported by the authors of 6.6% when standard subdural and depth intracranial electrodes were used. There were no deaths or permanent neurological deficits related to electrode implantation. Conclusions The authors demonstrate the use of hybrid subdural strip and grid electrodes containing high-density microwire arrays and standard clinical

  5. Copeptin in aneurysmal subarachnoid hemorrhage

    OpenAIRE

    2012-01-01

    Copeptin is a peptide derived from pre-provasospression along with arginine vasospressin. In the setting of aneurysmal subarachnoid hemorrhage (SAH), elevated serum copeptin levels correlate with vasospasm, inpatient mortality, mortality at 1 year, and poor functional outcome at 1 year. The potential role of serum copeptin levels in the management of patients with aneurysmal SAH is promising and should be explored further.

    We sought to determine preventability for cases of obstetric hemorrhage, identify preventable factors, and compare differences between levels of hospital. We retrospectively reviewed a 1-year cohort of severe and near-miss obstetric hemorrhage in an urban perinatal network. An expert panel, using a validated preventability model, reviewed all cases. Preventability and distribution of preventability factors were compared between levels of hospital care. Sixty-three severe and near-miss obstetric hemorrhage cases were identified from 11 hospitals; 54% were deemed potentially preventable. Overall preventability was not statistically different by level of hospital, and 88% were provider related. The only treatment-related preventability factors were significantly different between levels of hospital and significantly less common in level III hospitals (p < 0.01). The majority of obstetric hemorrhage was preventable. The most common potentially preventable factor was provider treatment error, and this was significantly more common in level II hospitals. New interventions should be focused on decreasing providers' treatment errors. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    The authors report the case of a 56-year-old previously healthy man who presented with a 4-month history of postural headache accompanied by nausea and vomiting. The results of initial imaging studies of the brain were normal. Repeated MR imaging demonstrated bilateral subdural hematomas which were drained and reaccumulated over a period of time. Spinal myelography revealed a cerebrospinal fluid leak at the C1-2 level. A cervical epidural blood patch, with repeated injections of 10 ml autologous blood at the site of the leak, dramatically improved the headache within 24 hours and eliminated the recurrent subdural hematomas. The results of follow-up computed tomography of the brain at 1, 4, 8, and 16 weeks were normal, and at 1-year follow-up the patient was completely free of symptoms and working.

    Intracranial dermoid cyst is a rare congenital benign disease, representing less than 0.5% of primary brain tumors. Nevertheless, if ruptured spontaneously or during surgery, it has a poor prognosis due to chemical meningitis. Therefore, it is essential to perform accurate diagnosis and proper treatment. We report an intracranial subdural dermoid cyst that may be misdiagnosed as extracranial or epidural lesion because of extension into the right foramen ovale, and describe the CT and MR imaging findings.

    Proteasome inhibitors (PI) and immunomodulatory agents (IMIDs) have improved the overall survival (OS) of patients with multiple myeloma (MM), but concerns have been raised about increased incidence of extramedullary disease (EMD) after the combined use of PIs and IMIDs for upfront therapy. We evaluated whether the addition of lenalidomide to bortezomib-based front-line regimens precipitated earlier development of EMD. We reviewed the charts of 117 MM patients (median follow-up from diagnosis 6·1 years; range 0·1-10·2 years) enrolled in eight clinical trials of first-line treatment with bortezomib-based regimens, with or without lenalidomide. We assessed development of EMD as extraosseous (distant from bone) or osseous (originating from bone) plasmacytomas. The primary endpoint was time from diagnosis until development of EMD, based on imaging, biopsy and/or physical examination. Any form of EMD at progression was observed in 40 (34·2%) patients, including 21 (18%) osseous, 8 (7%) extraosseous and 11 (9%) both osseous and extraosseous. Median OS was 0·9 years (range 0·1-4·8 years) after extraosseous EMD development. Sensitivity analyses with follow-up times truncated at 5 years detected no statistically significant difference in rates of any EMD form between the two groups (P > 0·2 for each comparison). Therefore, we observed no evidence that bortezomib-lenalidomide-based front-line therapy precipitates earlier EMD. © 2015 John Wiley & Sons Ltd.

    Acute myeloid leukemia (AML) relapse after allogeneic hematopoietic cell transplant (allo-HCT) is challenging. Data on extramedullary relapse (EMR) after allo-HCT are limited. We analyzed 215 patients with AML who underwent allo-HCT in our institution between January 2005 and December 2015. We limited this retrospective review to patients who received a MA conditioning, were in complete remission (CR) at the time of transplant and who received a matched sibling transplant, all other patients were excluded to avoid heterogeneity. Seventy-seven (35.8%) patients experienced disease relapse, 45 had BMR, and 32 had EMR. The only variable that was statistically associated with EMR post allo-HCT was male sex (OR = 3.2 (1.2, 8.2), p-value = 0.01); there was a trend for association between transplant in >CR2 and EMR (OR = 0.38 (0.14, 1.06), p-value = 0.06). The median overall survival (OS) after relapse for all relapses was 10 months (95% CI 4.839-15.161). The median OS for BMR group was 8 months (95% CI 2.850-13.150) and 14 months for the EMR group (95% CI 5.776-22.224); however, this was not statistically significant, p-value = 0.4. Multivariate analysis revealed that gender, treatment modality, and time from allo-HCT to relapse (≥12 vs. <12 months) have significant association with the post-relapse death. Male gender was the only significant factor associated with EMR.

    The detectability of high frequency oscillations (HFO, >200Hz) in the intraoperative ECoG is restricted by their low signal-to-noise ratio (SNR). Using the somatosensory evoked HFO, we quantify how HFO detectability can benefit from a custom-made low-noise amplifier (LNA). In 9 patients undergoing tumor surgery in the central region, subdural strip electrodes were placed for intraoperative neurophysiological monitoring. We recorded the somatosensory evoked potential (SEP) simultaneously by custom-made LNA and by a commercial device (CD). We varied the stimulation rate between 1.3 and 12.7Hz to tune the SNR of the N20 component and the evoked HFO and quantified HFO detectability at the single trial level. In three patients we compared Propofol® and Sevoflurane® anesthesia. In the average, amplitude decreased in both in N20 and evoked HFO amplitude with increasing stimulation rate (pnoise amplification improves the detection of the evoked HFO in recordings with subdural electrodes with low impedance. Low-noise EEG might critically improve the detectability of interictal spontaneous HFO in subdural and possibly in scalp recordings.

    Primary spinal tumors are rare. Symptoms depend on the size and location of the tumor. A patient presented with a rare clinical finding, Brown-Séquard syndrome. The symptoms were caused by an extramedullary tumor compressing on the thoracic spinal cord. Pathologic examination showed cavernous hemangioma with growth both intradurally and extradurally. This is an extremely rare finding; to our knowledge, only 1 case report has been published before in which a spinal cavernous hemangioma had intradural and extradural growth. The clinical symptoms of Brown-Séquard syndrome have not been described before in the findings of spinal cavernous hemangiomas. Copyright © 2016 Elsevier Inc. All rights reserved.

    Hemorrhage of the kidneys and adrenal glands has many etiologies. In the adrenal glands, trauma, anticoagulation, stress, sepsis, surgery, and neoplasms are common causes of hemorrhage. In the kidneys, reasons for hemorrhage include trauma, bleeding diathesis, vascular diseases, infection, infarction, hemorrhagic cyst rupture, the Antopol-Goldman lesion, and neoplasms. Angiomyolipoma and renal cell carcinoma are the neoplasms most commonly associated with hemorrhage in the kidneys and adrenal cortical carcinoma, metastases, and pheochromocytoma are associated with hemorrhage in the adrenal glands. Understanding the computed tomography and magnetic resonance imaging features, and causes of hemorrhage in the kidneys and adrenal glands is critical. It is also important to keep in mind that mimickers of hemorrhage exist, including lymphoma in both the kidneys and adrenal glands, and melanoma metastases in the adrenal glands. Appropriate imaging follow-up of renal and adrenal hemorrhage should occur to exclude an underlying malignancy as the cause. If there is suspicion for malignancy that cannot be definitively diagnosed on imaging, surgery or biopsy may be warranted. Angiography may be indicated when there is a suspected underlying vascular disease. Unnecessary intervention, such as nephrectomy, may be avoided in patients with benign causes or no underlying disease. Appropriate management is dependent on accurate diagnosis of the cause of renal or adrenal hemorrhage and it is incumbent upon the radiologist to determine the etiology.

    A 20-year-old woman with a 2-year history of histologically confirmed palmoplantar keratoderma due to psoriasis, resistant to several topical agents, was admitted to the Department of Dermatology, Uludag University, Bursa, Turkey. Therapy with oral acitretin (0.5 mg/kg/day, 35 mg/day) was initiated. A month after starting acitretin treatment, she noted slight reddening of the second left fingernail. Clinical examination revealed red-brown discoloration of the second fingernail associated with subungual hemorrhage involving the proximal nail bed (lunula region) (Fig. 1). The nail change was asymptomatic. The patient complained only of discoloration underneath the nail plate. No abnormalities were detected on the skin, mucous membranes, or toenails/other fingernails. The patient denied exposure to microtrauma or any other drugs. The erythrocyte sedimentation rate, full blood cell count, electrolytes, renal and hepatic tests, and serum lipids were normal. Coagulation tests, including blood clotting time, international normalized ratio, activated partial thromboplastin time, thrombin time, platelet number, and function tests, were within normal levels. Treatment with acitretin was discontinued, and the nail change resolved completely after 3 weeks. A similar episode of subungual hemorrhage recurred, however, within 48 h after re-challenge with a lower dose of acitretin (25 mg/day). The drug was definitively stopped and the eruption faded again within a week. An objective causality assessment suggests that subungual hemorrhage was probably related to acitretin in this patient.

  18. Cerebral vasospasm after subarachnoid hemorrhage.

    2003-04-01

    To summarize new pathophysiologic insights and recent advances in the diagnosis and treatment of cerebral vasospasm after aneurysmal subarachnoid hemorrhage. Important, newly recognized mediators of cerebral arterial spasm after subarachnoid hemorrhage include superoxide free radicals, ferrous hemoglobin (which acts as a nitric oxide scavenger), endothelins, protein kinase C, and rho kinase. Microvascular dysfunction and autoregulatory failure also has been an area of increasing research focus in recent years. New diagnostic modalities include measures of cerebral blood flow such as single-photon emission computed tomography and perfusion computed tomography, magnetic resonance imaging, intracranial brain oxygen tension probes, and jugular venous oxygen saturation monitors. Proton magnetic resonance spectroscopy and microdialysis can detect tissue biochemical abnormalities, but these techniques have not found their way into routine clinical practice as of yet. In addition to nimodipine and hypertensive hypervolemic therapy, promising new treatments for vasospasm or its ischemic complications include magnesium sulfate, fasudil hydrochloride, tirilazad mesylate, erythropoietin, and induced hypothermia. Balloon angioplasty has emerged as the primary weapon for treating medically refractory ischemia from vasospasm and in many centers is being used as a first-line treatment or even prophylactically. The neurointensive care management of vasospasm after subarachnoid hemorrhage has evolved significantly over the past 10 years, with many new diagnostic modalities and promising treatments now available. Clinical trials are needed to evaluate the efficacy of these new techniques and to further define the optimal management of this often devastating complication.

    Crimean-Congo hemorrhagic fever (CCHF) is an acute infectious disease caused by CCHF virus (CCHFV), a member of the family Bunyaviridae, genus Nairovirus. The case fatality rate of CCHF ranges from 10-40%. Because CCHF is not present in Japan, many Japanese virologists and clinicians are not very familiar with this disease. However, there remains the possibility of an introduction of CCHFV or other hemorrhagic fever viruses into Japan from surrounding endemic areas. Development of diagnostic laboratory capacity for viral hemorrhagic fevers is necessary even in countries without these diseases. At the National Institute of Infectious Diseases, Tokyo, Japan, laboratory-based systems such as recombinant protein-based antibody detection, antigen-capture and pathological examination have been developed. In this review article, epidemiologic and clinical data on CCHF in the Xinjiang Uygur Autonomous Region, compiled through field investigations and diagnostic testing utilizing the aforementioned laboratory systems, are presented. CCHFV infections are closely associated with the environmental conditions, life styles, religion, occupation, and human economic activities. Based on these data, preventive measures for CCHFV infections are also discussed.

    2012-02-01

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O hematoma subdural intracraniano é uma complicação rara após raquianestesia. O diagnóstico é muitas vezes difícil porque os sintomas iniciais são os mesmos da cefaleia pós-punção da dura-máter. O objetivo é relatar o caso de um hematoma subdural diag nosticado precocemente, após uma raquianestesia realizada com agulha de calibre fino e punção única. RELATO DO CASO: Paciente de 48 anos, ASA I, submetida a raquianestesia para cirurgia de correção de incontinência urinária. Foi realizada a raquianestesia com agulha 27G Quincke e punção única. A cirurgia foi sem intercorrências, e a paciente recebeu alta hospitalar. Após 48 horas da punção raquidiana, a paciente relatou cefaleia de início súbito, de forte intensidade, acometendo principalmente a região orbitária, mas também a região temporal, com melhora importante no decúbito dorsal e acompanhada de dois episódios de vômitos. Foi solicitada tomografia de crânio que revelou a presença de um hematoma subdural agudo frontotemporoparietal esquerdo. Foi indicado tratamento conservador com analgésicos, dexametasoma e hidantoína. Após 17 dias, apresentou quadro de cefaleia intensa, acompanhada de dormência e paresia do membro superior direito, e distúrbio da fala e comportamento. O hematoma foi drenado cirurgicamente. A paciente evoluiu bem sem sequelas. CONCLUSÕES: A cefaleia é a complicação mais frequente após raquianestesia e é considerada de evolução benigna. Faz com que diagnósticos potencialmente fatais, como o hematoma subdural, não sejam feitos em muitos casos, ou sejam tardios. Este caso descreve uma ocorrência rara, um hematoma subdural agudo após uma raquianestesia com agulha fina em uma paciente sem fatores de risco para sangramento

  1. Risk factors for chronic subdural haematoma formation do not account for the established male bias.

    The 'subdural space' is an artefact of inner dural border layer disruption: it is not anatomical but always pathological. A male bias has long been accepted for chronic subdural haematomas (CSDH), and increased male frequencies of trauma and/or alcohol abuse are often cited as likely explanations: however, no study has validated this. We investigated to see which risk factors accounted for the male bias with CSDH. Retrospective review of prospectively collected data. A male bias (M:F 97:58) for CSDH was confirmed in n=155 patients. The largest risk factor for CSDH was cerebral atrophy (M:F 94% vs. 91%): whilst a male bias prevailed in mild-moderate cases (M:F 58% vs. 41%), a female bias prevailed for severe atrophy (F:M 50% vs. 36%) (χ(2)=3.88, P=0.14). Risk factors for atrophy also demonstrated a female bias, some approached statistical significance: atrial fibrillation (P=0.05), stroke/TIA (P=0.06) and diabetes mellitus (P=0.07). There was also a trend for older age in females (F:M 72±13 years vs. 68±15 years, P=0.09). The third largest risk factor, after atrophy and trauma (i.e. anti-coagulant and anti-platelet use) was statistically significantly biased towards females (F:M 50% vs. 33%, P=0.04). No risk factor accounted for the established male bias with CSDH. In particular, a history of trauma (head injury or fall [M:F 50% vs. 57%, P=0.37]), and alcohol abuse (M:F 17% vs. 16%, P=0.89) was remarkably similar between genders. No recognised risk factor for CSDH formation accounted for the established male bias: risk factor trends generally favoured females. In particular, and in contrast to popular belief, a male CSDH bias did not relate to increased male frequencies of trauma and/or alcohol abuse. Crown Copyright © 2015. Published by Elsevier B.V.

    Posttraumatic epileptic seizures (PTS) are a serious complication in patients with subdural haematoma (SDH). However, to date, several studies have shown discordances about SDH-associated seizures in terms of incidence, risk factors and prophylactic antiepileptic treatment. The aim of this study was to analyse the incidence, risk factors of PTS and the role of prophylactic antiepileptic treatment in patients with SDH. A systematic literature review examining PTS in patients with SDH was performed using PubMed gateway, Cochrane Central Register of Controlled Trials, and Excerpta Medica dataBASE between September 1961 and February 2016. Search terms included subdural haematoma, seizure, epilepsy, prophylactic antiepileptic drugs, anticonvulsive medication, and risk factors. Human-based clinical studies focusing on epileptic seizures in patients with SDH. PRISMA statements were used for assessing data quality. Two independent reviewers extracted data from included studies and disagreement was solved by consensus. Twenty-four studies were identified for inclusion into the study. Overall incidence of early PTS (ePTS) and late PTS (lPTS)/2 years was 28% and 43% in acute SDH (aSDH) whereas the incidence of e- and lPTS was lower in chronic SDH (cSDH; 5.3% vs. 10%). Overall risk factors for PTS in patients with aSDH were: 24h postoperative Glasgow Coma Score (GCS) score below 9 (OR 10.5), craniotomy (OR 3.9), preoperative GCS below 8 (OR 3.1). In patients with cSDH the risk factors were alcohol abuse (OR 14.3), change of mental status (OR 7.2), previous stroke (OR 5.3) and density of haematoma in computer tomography (OR 3.8). Age, sex, haematoma size/side and midline shifts were not significant risk factors for PTS in both types of SDH. In prevention of PTS phenytoin and levetiracetam showed similar efficacy (OR 1.3), whereas levetiracetam was associated with significantly lower adverse effects (OR 0.1). Most of the studies were of retrospective nature with a small sample

    Accurate intraoperative localization of small intradural extramedullary thoracolumbar (T-1 to L-3 level) spinal cord tumors is vital when minimally invasive techniques, such as hemilaminectomy, are used to excise these lesions. In this study, the authors describe a simple and effective method of preoperative MRI localization of small intradural extramedullary tumors using cod liver oil capsules. Thirty-five patients with intradural tumors underwent preoperative MRI localization the evening prior to surgery. Patients were positioned prone in the MRI gantry, mimicking the intraoperative position. Nine capsules were placed in 3 rows to cover the lesion. This localization was used to guide the level for a minimally invasive approach using a hemilaminectomy to excise these tumors. The mean patient age was 51.5 ± 14.3 years, and the mean body mass index was 24.1 ± 3.5 kg/m(2). Twenty-two tumors involved the thoracic spine, and 13 involved the upper lumbar spine from L-1 to L-3. The mean tumor size was 2.2 ± 1.0 cm. Localization was accurate in 34 patients (97.1%). Accurate localization with the described method is quick, safe, cost-effective, and noninvasive with no exposure to radiation. It also reduces operating time by eliminating the need for intraoperative fluoroscopy.

    Full Text Available Hemorrhagic stroke is a devastating cerebrovascular disease with significant morbidity and mortality worldwide. Thrombospondins (TSPs, as matricellular proteins, belong to the TSP family which is comprised of five members. All TSPs modulate a variety of cellular functions by binding to various receptors. Recently, TSPs gained attention in the area of hemorrhagic stroke, especially TSP-1. TSP-1 participates in angiogenesis, the inflammatory response, apoptosis, and fibrosis after hemorrhagic stroke through binding to various molecules including but not limited to CD36, CD47, and TGF-β. In this review, we will discuss the roles of TSPs in hemorrhagic stroke and focus primarily on TSP-1.

  8. Computational Study of Subdural Cortical Stimulation: Effects of Simulating Anisotropic Conductivity on Activation of Cortical Neurons.

    Hyeon Seo

    Full Text Available Subdural cortical stimulation (SuCS is an appealing method in the treatment of neurological disorders, and computational modeling studies of SuCS have been applied to determine the optimal design for electrotherapy. To achieve a better understanding of computational modeling on the stimulation effects of SuCS, the influence of anisotropic white matter conductivity on the activation of cortical neurons was investigated in a realistic head model. In this paper, we constructed pyramidal neuronal models (layers 3 and 5 that showed primary excitation of the corticospinal tract, and an anatomically realistic head model reflecting complex brain geometry. The anisotropic information was acquired from diffusion tensor magnetic resonance imaging (DT-MRI and then applied to the white matter at various ratios of anisotropic conductivity. First, we compared the isotropic and anisotropic models; compared to the isotropic model, the anisotropic model showed that neurons were activated in the deeper bank during cathodal stimulation and in the wider crown during anodal stimulation. Second, several popular anisotropic principles were adapted to investigate the effects of variations in anisotropic information. We observed that excitation thresholds varied with anisotropic principles, especially with anodal stimulation. Overall, incorporating anisotropic conductivity into the anatomically realistic head model is critical for accurate estimation of neuronal responses; however, caution should be used in the selection of anisotropic information.

    To investigate the reason for and the course of the double-layer appearance in the postoperative computed tomographies (CTs) of chronic subdural hematoma (CSDHs). We reviewed CSDH cases that were operated on during the last 3 years, between January 2008 and December 2010. We checked the preoperative, early postoperative, and late postoperative CTs of these patients. We investigated the relationship between the formation of a double-layer appearance and the prognoses and demographic characteristics of the patients. Our database included 119 cases. A double-layer appearance was found in the postoperative CTs of 34 cases. The mean age of double-layer cases was older (72.5 ± 12.1) than that of the remaining 85 cases (63.1 ± 17.8). We did not find any relationship between the double-layer appearance and the reoperation/recurrence/death rates. The double-layer appearance after evacuation of a CSDH might be caused by enlargement of the subarachnoid space and is not related to the presence of any residual hematoma. This appearance is not considered as a reason for reoperation.

  10. Intracranial subdural hematoma coexisting with improvement in spontaneous intracranial hypotension after an epidural blood patch

    Full Text Available A 36-year-old male had spontaneous intracranial hypotension (SIH presenting with refractory headache for 4 months. Multiple epidural blood patches (EBPs yielded relief of symptoms, but the course was complicated, with asymptomatic intracranial subdural hematoma (SDH. Except for SDH, other radiological diagnostic signs of SIH were resolved and the patient’s headaches improved after EBP. Owing to a mass effect and persistent cerebrospinal fluid (CSF leakage, surgical repair of the spinal leakage was performed, but no cranial procedures were carried out. Postoperatively, the SDH completely resolved, but there was still CSF leakage at the level where surgery was performed. The patient has remained free of headache or other events for 3 years. It was reduction rather than elimination of the spinal CSF leak that yielded remission of SIH. In summary, intracranial SDH can be a complication of inadequately treated SIH (i.e. persistent minor CSF leakage. Management of SDH should focus on correction of the underlying SIH rather than craniotomy for hematoma evacuation.

    Platinum microwires, terminated at regular intervals to form a grid of contacts, were used to record electric potentials at the surface of the cerebral cortex in human subjects. The microwire grids were manufactured commercially with 75 μm platinum wire and 1 mm grid spacing, and are FDA approved. Because of their small size and spacing, these grids could be used to explore the scale of spatiotemporal dynamics in cortical surface potentials. Electrochemical impedance spectroscopy was used to characterize their recording properties and develop a frequency-dependent electrical model of the micro-electrodes. Data recorded from multiple sites in human cortex were analyzed to explore the relationship between linear correlation and separation distance. A model was developed to explore the impact of cerebrospinal fluid on signal spread among electrodes. Spatial variation in the per-electrode performance decoding articulated speech from face-motor and Wernicke's areas of cortex was explored to understand the scale of information processing at the cortex. We conclude that there are important dynamics at the millimeter scale in human subdural electrocorticography which may be important in maximizing the performance of neural prosthetic applications.

    Spongostan™ is a sterile, water-insoluble, porcine gelatin absorbable sponge, which is widely used as a hemostatic material. The aim of this study is to test the anti-fibrotic capacity of Spongostan™, using a craniotomy model in an experimental rabbit model. Eighteen rabbits were divided into two groups: Each group consisted of 9 rabbits, duratomy plus Spongostan™ (group 1), and duratomy without Spongostan™ (group 2). Right parietal bone was removed via trephine and low speed drill and dura was opened. On the group 1 rabbits, an appropriate piece of Spongostan™ was meticulously placed under dural layer. On group 2 rabbits, same procedures were repeated without Spongostan™. Histological sections were taken from each group and evaluated for degree of fibrosis and collagen fibers. There was marked increase in number of fibroblasts and collagen fibers in group 2 rabbits, however most of the rabbits in Spongostan™ group demonstrate scarce histopathological findings for fibrosis. We conclude that an appropriately placed subdural Spongostan™ over cerebral tissue may prevent postoperative surgical adhesions after neurosurgical operations.

    Isolated oculomotor nerve palsy is well known as a symptom of microvascular infarction and intracranial aneurysm, but unilateral oculomotor nerve palsy as an initial manifestation of chronic subdural hematoma (CSDH) is a rare clinical condition. We report a rare case of an 84-year-old woman with bilateral CSDH who presented with unilateral oculomotor nerve palsy as the initial symptom. The patient, who had a medical history of minor head injury 3 weeks prior, presented with left ptosis, diplopia, and vomiting. She had taken an antiplatelet drug for lacunar cerebral infarction. Computed tomography (CT) of the head showed bilateral CSDH with a slight midline shift to the left side. She underwent an urgent evacuation through bilateral frontal burr holes. Magnetic resonance angiography (MRA) after evacuation revealed no intracranial aneurysms, but constructive interference in steady-state (CISS) magnetic resonance imaging (MRI) revealed that the left posterior cerebral artery (PCA) ran much more anteriorly and inferiorly compared with the right PCA and the left oculomotor nerve passed very closely between the left PCA and the left superior cerebellar artery (SCA). There is the possibility that the strong compression to the left uncus, the left PCA, and the left SCA due to the bilateral CSDH resulted in left oculomotor nerve palsy with an initial manifestation without unconsciousness. Unilateral oculomotor nerve palsy as an initial presentation caused by bilateral CSDH without unconsciousness is a rare clinical condition, but this situation is very important as a differential diagnosis of unilateral oculomotor nerve palsy.

    Objectives: To systematically review the literature on dating subdural hematomas (SDHs) on CT and MRI scans. Methods: We performed a systematic review in MEDLINE, EMBASE and Cochrane to search for articles that described the appearance of SDHs on CT or MRI in relation to time between trauma and scanning. Two researchers independently screened the articles, assessed methodological quality and performed data extraction. Medians with interquartile ranges were calculated. Differences were tested with a Mann–Whitney U or Kruskal–Wallis H test. Results: We included 22 studies describing 973 SDHs on CT and 4 studies describing 83 SDHs on MRI. Data from 17 studies (413 SDHs) could be pooled. There were significant differences between time intervals for the different densities on CT (p < 0.001). Time interval differed significantly between children and adults for iso- and hypodensity (p = 0.000) and hyperdensity (p = 0.046). Time interval did not differ significantly between abused and non-abused children. On MRI, time intervals for different signal intensities on T1 and T2 did not differ significantly (p = 0.108 and p = 0.194, respectively). Conclusions: Most time intervals of the different appearances of SDHs on CT and MRI are broad and overlapping. Therefore CT or MRI findings cannot be used to accurately date SDHs.

    This prospective trial was designed to evaluate the incidence of Terson syndrome in patients suffering from subarachnoid hemorrhage, intracerebral hemorrhage, or traumatic brain injury and whether consequences necessarily derive from the intraocular hemorrhage itself. Two ophthalmologic examinations were performed to identify patients with Terson syndrome. Data on initial Glasgow Coma Scale, Hunt and Hess and Fisher grades, aneurysm site and diameter, and volume of hemorrhage in intracerebral hemorrhage patients were correlated to the location and course of Terson syndrome. Follow-up was performed after 3 months, including clinical and ophthalmologic investigations. The data showed that 16 of 83 subarachnoid hemorrhage patients (19.3%), 2 of 22 intracerebral hemorrhage patients (9.1%), and 1 of 32 traumatic brain injury patients (3.1%) suffered from Terson syndrome. Low Glasgow Coma Scale (p = 0.002), high Hunt and Hess grade (p Terson syndrome. The neurological outcome in subarachnoid hemorrhage patients suffering from Terson syndrome was worse compared with that of subarachnoid hemorrhage patients without Terson syndrome (p = 0.005), and vitrectomy was performed in seven eyes of six patients due to poor visual acuity. Terson syndrome is underestimated in patients with subarachnoid hemorrhage and a rare pathology in intracerebral hemorrhage as well as in traumatic brain injury patients. Spontaneous regression of the intraocular hemorrhage may be seen, but in half of the patients, vitrectomy is necessary to prevent permanent visual deterioration.

    Recent evidence has suggested a potential beneficial effect of aspirin on the risk of aneurysm rupture. This benefit must be weighed against its potential adverse effects as an antiplatelet agent in the setting of acute aneurysmal subarachnoid hemorrhage (SAH). A total of 747 consecutive patients with cerebral aneurysms were reviewed, comparing demographics, aneurysm features, presenting clinical and radiographic grades, vasospasm, and outcome at 1 year between patients with aneurysmal SAH taking aspirin on presentation and those who were not. The rate of hemorrhagic presentation was significantly greater in patients not taking aspirin (40% vs. 28%; P = 0.016). Among 274 patients presenting with aneurysmal SAH, there was no significant difference in presenting clinical (Hunt and Hess) and radiographic (Fisher) grade between patients taking aspirin and those who were not. There was also no significant difference in the rate of subsequent angiographic and delayed cerebral ischemia. Multivariate analysis of outcome at 1 year found only increasing age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.04-1.12), Hunt and Hess grade (OR 3.01, 95% CI 1.81-5.03), and associated hypertension (OR 3.30, 95% CI 1.39-7.81) to be statistically significant risk factors for poor outcome (death or dependence), whereas aspirin use was not associated with poor outcome (OR 1.19, 95% CI 0.35-4.09; P = 0.78). In the present study, patients taking aspirin had a lower rate of hemorrhagic presentation. In addition, taking aspirin did not adversely impact presenting clinical grade or radiographic grade, vasospasm, and outcome in the setting of aneurysmal SAH. Copyright © 2014 Elsevier Inc.

    Full Text Available Leptospirosis is one of the most widespread zoonoses in the world, although the mechanisms responsible for the pathogenesis of spirochetes of the genus Leptospira are largely unknown. Human infection occurs either by direct contact with infected animals or indirectly, through contact with water or soil contaminated with urine, as the spirochetes easily penetrate human skin. The present report exposes the case of a female patient, diagnosed with leptospirosis after having had contact with a dog infected by Leptospira sp. that developed pulmonary hemorrhage, acute respiratory distress syndrome and acute renal failure.

    Malaria remains a significant public health problem of the tropical world. Falciparum malaria is most prevalent in the sub-Saharan African region, which harbors about 90% of all malaria cases and fatalities globally. Infection by the falciparum species often manifests with a spectrum of multi-organ complications (eg, cerebral malaria), some of which are life-threatening. Spontaneous subdural empyema is a very rare complication of cerebral malaria that portends a very poor prognosis unless diagnosed and treated promptly. We report a case of spontaneous subdural empyema in a 58-year-old woman from Tanzania who presented with high-grade fever, decreased urine output, and altered sensorium.

    Full Text Available With the exception of trauma, intraperitoneal hemorrhage in young women is caused by the high frequency of ectopic pregnancy and ovarian bleeding. Here, we describe a case of idiopathic omental hemorrhage, which is a rare cause of intraperitoneal hemorrhage. Intraperitoneal hemorrhage was suspected in a 38-year-old Japanese woman based on contrast-enhanced computed tomography. Her last menstrual period was 23 days prior, and ovarian bleeding was considered based on bloody ascites revealed by culdocentesis. She underwent emergency surgery for hypovolemic shock. Although both ovaries were of normal size and no abnormal findings were observed, we performed a partial omentectomy because multiple clots were attached only to the greater omentum. Postoperatively, no rebleeding occurred, and she was discharged 11 days after the surgery. Because she did not have a clear history of trauma and underlying disease, idiopathic omental hemorrhage was diagnosed.

    Kynurenic acid (KYNA) is the end stage metabolite of tryptophan produced mainly by astrocytes in the central nervous system (CNS). It has neuroprotective activities but can be elevated in the neuropsychiatric disorders. Toxic effects of KYNA in the CNS are unknown. The aim of this study was to assess the effect of the subdural KYNA infusion on the spinal cord in adult rats. A total of 42 healthy adult rats were randomly assigned into six groups and were infused for 7 days with PBS (control) or 0.0002 pmol/min, 0.01 nmol/min, 0.1 nmol/min, 1 nmol/min, and 10 nmol/min of KYNA per 7 days. The effect of KYNA on spinal cord was determined using histological and electron microscopy examination. Myelin oligodendrocyte glycoprotein (MOG) was measured in the blood serum to assess a degree of myelin damage. In all rats continuous long-lasting subdural KYNA infusion was associated with myelin damage and myelin loss that was increasingly widespread in a dose-depended fashion in peripheral, sub-pial areas. Damage to myelin sheaths was uniquely related to the separation of lamellae at the intraperiod line. The damaged myelin sheaths and areas with complete loss of myelin were associated with limited loss of scattered axons while vast majority of axons in affected areas were morphologically intact. The myelin loss-causing effect of KYNA occurred with no necrosis of oligodendrocytes, with locally severe astrogliosis and no cellular inflammatory response. Additionally, subdural KYNA infusion increased blood MOG concentration. Moreover, the rats infused with the highest doses of KYNA (1 and 10 nmol/min) demonstrated adverse neurological signs including weakness and quadriplegia. We suggest, that subdural infusion of high dose of KYNA can be used as an experimental tool for the study of mechanisms of myelin damage and regeneration. On the other hand, the administration of low, physiologically relevant doses of KYNA may help to discover the role of KYNA in control of physiological

    In patients with pharmacoresistant focal-onset seizures, invasive presurgical workup can identify epilepsy surgery options when noninvasive workup has failed. Yet, the potential benefit must be balanced with procedure-related risks. This study examines risks associated with the implantation of subdural strip and grid, and intracerebral depth electrodes. Benefit of invasive monitoring is measured by seizure outcomes. Diagnostic procedures made possible by electrode implantation are described. Retrospective evaluation of invasive workups in 242 epilepsy surgery candidates and additional 18 patients with primary brain tumors implanted for mapping only. Complications are scaled in five grades of severity. A regression analysis identifies risk factors for complications. Outcome is classified according to Engel's classification. Complications of any type were documented in 23% of patients, and complications requiring surgical revision in 9%. We did not find permanent morbidity or mortality. Major risk factor for complications was the implantation of grids and the implantation of electrode assemblies comprising strip and grid electrodes. Depth electrodes were significantly correlated with a lower risk. Tumors were not correlated with higher complication rates. Chronic invasive monitoring of 3-40 days allowed seizure detection in 99.2% of patients with epilepsy and additional extensive mapping procedures. Patients with epilepsy with follow-up >24 months (n = 165) had an Engel class 1a outcome in 49.7% if epilepsy surgery was performed, but only 6.3% when surgery was rejected. The benefit of chronic invasive workup outweighs its risks, but complexity of implantations should be kept to a minimum. Wiley Periodicals, Inc. © 2012 International League Against Epilepsy.

    2016-08-01

    Nontraumatic subdural hematoma (NTSDH) is a common neurosurgical disease process, with mortality reported as high as 13%. Seizure has a known association with NTSDH, although patient outcomes have not previously been well studied in this population. The purpose of this study was to examine the relationship between in-hospital seizure and inpatient outcomes in NTSDH. Using the University HealthSystem Consortium (UHC) database, we performed a retrospective cohort study of adults with a principal diagnosis of NTSDH (International Classification of Diseases, Ninth Revision code 43.21) between 2011 and 2015. Patients with in-hospital seizure (International Classification of Diseases, Ninth Revision codes 34500-34591, 78033, 78039) were compared with those without. Patients with a history of seizure before arrival were excluded. Patient demographics, hospital length of stay (LOS), intensive care unit stay, in-hospital mortality, and direct costs were recorded. A total 16,928 patients with NTSDH were identified. Mean age was 69.2 years, and 64.7% were male. In-hospital seizure was documented in 744 (4.40%) patients. Hospital LOS was 17.64 days in patients with seizure and 6.26 days in those without (P stay increased from 3.36 days without seizure to 9.36 days with seizure. In-hospital mortality was 9.19% in patients without seizure and 16.13% in those with seizure (P < 0.0001). Direct costs were $12,781 in patients without seizure and $38,110 in those with seizure (P < 0.0001). Seizure in patients with NTSDH correlates with significantly increased total LOS and increased mortality. Direct costs are similarly increased. Further studies accounting for effects of illness severity are necessary to validate these results. Copyright © 2016 Elsevier Inc. All rights reserved.

  12. Association between biomarkers and clinical characteristics in chronic subdural hematoma patients assessed with lasso regression.

    Directory of Open Access Journals (Sweden)

    Are Hugo Pripp

    Full Text Available Chronic subdural hematoma (CSDH is characterized by an "old" encapsulated collection of blood and blood breakdown products between the brain and its outermost covering (the dura. Recognized risk factors for development of CSDH are head injury, old age and using anticoagulation medication, but its underlying pathophysiological processes are still unclear. It is assumed that a complex local process of interrelated mechanisms including inflammation, neomembrane formation, angiogenesis and fibrinolysis could be related to its development and propagation. However, the association between the biomarkers of inflammation and angiogenesis, and the clinical and radiological characteristics of CSDH patients, need further investigation. The high number of biomarkers compared to the number of observations, the correlation between biomarkers, missing data and skewed distributions may limit the usefulness of classical statistical methods. We therefore explored lasso regression to assess the association between 30 biomarkers of inflammation and angiogenesis at the site of lesions, and selected clinical and radiological characteristics in a cohort of 93 patients. Lasso regression performs both variable selection and regularization to improve the predictive accuracy and interpretability of the statistical model. The results from the lasso regression showed analysis exhibited lack of robust statistical association between the biomarkers in hematoma fluid with age, gender, brain infarct, neurological deficiencies and volume of hematoma. However, there were associations between several of the biomarkers with postoperative recurrence requiring reoperation. The statistical analysis with lasso regression supported previous findings that the immunological characteristics of CSDH are local. The relationship between biomarkers, the radiological appearance of lesions and recurrence requiring reoperation have been inclusive using classical statistical methods on these data

    Spontaneous vitreous hemorrhage is a serious disease whose incidence is 7 per 100,000 people per year. Posterior vitreous detachment with or without retinal tear, diabetic retinopathy, vascular proliferation after retinal vein occlusion, age-related macular degeneration and Terson's syndrome are the most common causes. Repeated ultrasonography may ignore a retinal tear or detachment and delay vitrectomy that is the only treatment for serious forms. The occurrence of retinal tear or detachment is a surgical emergency as well as rubeosis or diabetic tractional retinal detachment involving the macula. Intravitreal injection of antiangiogenic agents are helpful in clearing the vitreous cavity, facilitating laser photocoagulation and reducing the risks of bleeding during preretinal neovascular membranes dissection.

    Germinal matrix hemorrhage is a frequent complication of prematurity and can be associated with adverse neurodevelopmental outcome, depending on its severity. In addition to parenchymal damage, intraventricular residues of hemorrhage and hydrocephalus MR imaging findings include superficial siderosis. The purpose of this study was to investigate the prevalence and location of superficial siderosis in patients with a history of germinal matrix hemorrhage. We retrospectively identified patients with a history of germinal matrix hemorrhage who underwent MR imaging in our institution between 2008 and 2016. Imaging was evaluated for the presence and location of superficial siderosis. The presence of subependymal siderosis and evidence of hydrocephalus were assessed. Thirty-seven patients with a history of germinal matrix hemorrhage were included; 86.5% had preterm births. The mean age at the first MR imaging was 386 days (range 2-5140 days). The prevalence of superficial siderosis was 67.6%. Superficial siderosis was detected significantly more often when MR imaging was performed within the first year of life (82.8% versus 12.5%, P germinal matrix hemorrhage, but it dissolves and has a low prevalence thereafter. A prospective analysis of its initial severity and speed of dissolution during this first year might add to our understanding of the pathophysiology of neurodevelopmental impairment after germinal matrix hemorrhages. © 2016 by American Journal of Neuroradiology.

    To report the observation of a case of carbon monoxide poisoning in a 5-year-old child causing significant vision loss, retinal hemorrhages, and bilateral vitreous hemorrhage. A 5-year-old male patient underwent ophthalmologic examination including indirect ophthalmoscopy with a 20D lens, slit-lamp biomicroscopy, and bilateral 25 gauge pars plana vitrectomies. The patient did not fix and follow, but did blink in response to bright light. Pupils were reactive without afferent pupillary defect. Anterior examination was unremarkable and intraocular pressures were normal. Dilated funduscopic examination showed diffuse white, fluffy appearing vitreous haze bilaterally overlying the macula with scattered retinal hemorrhages and Roth spots throughout both retinas. The patient subsequently underwent 25 gauge pars plana vitrectomies in each eye, and findings during surgery were suggestive of vitreous hemorrhage in both eyes. Vitreous biopsy did not reveal any infectious or inflammatory cells. This is the second case of carbon monoxide poisoning causing vitreous changes. Given our findings, along with retinal hemorrhages, disk edema, retinal vein tortuosity, and internal limiting membrane hemorrhages, vitreous hemorrhage can be included as a manifestation of carbon monoxide retinopathy.

    Full Text Available Troponin (tr elevation in aneurysmal subarachnoid hemorrhage (SAH patients is often difficult to be appropriately assessed by clinicians, causing even disagreements regarding its management between neurosurgeons and cardiologists. The purpose of this article was to review the literature regarding the clinical interpretation of tr elevation in SAH. We searched for articles in PubMed using the key words: “troponin elevation” and “subarachnoid hemorrhage”. All of them, as well as relative neurosurgical books, were used for this review. Some type of cardiovascular abnormality develops in most SAH patients. Neurogenic stunned myocardium is a frequent SAH complication, due to catecholamine surge which induces cardiac injury, as evidenced by increased serum tr levels, electrocardiographic (ECG changes and cardiac wall motion abnormalities. Tr elevation, usually modest, is an early and specific marker for cardiac involvement after SAH and its levels peak about two days after SAH. Cardiac tr elevation predictors include poor clinical grade, intraventricular hemorrhage, loss of consciousness at ictus, global cerebral edema, female sex, large body surface area, lower systolic blood pressure, higher heart rate and prolonged Q-Tc interval. Elevated tr levels are associated with disability and death (especially tr >1 μg/L, worse neurological grade, systolic and diastolic cardiac dysfunction, pulmonary congestion, longer intensive care unit stay and incidence of vasospasm. Tr elevation is a common finding in SAH patients and constitutes a rightful cause of worry about the patients' cardiac function and prognosis. It should be therefore early detected, carefully monitored and appropriately managed by clinicians.

    Full Text Available A 15-year-old male high school football player presented with episodes of headache and complete body stiffness, especially in the arms, lower back, and thighs, immediately following a football game. This was accompanied by severe nausea and vomiting for several days. Viral meningitis was suspected by the primary clinician, and treatment with corticosteroids was initiated. Over the next several weeks, there was gradual symptom improvement and the patient returned to his baseline clinical status. The patient experienced a severe recurrence of the previous myriad of symptoms following a subsequent football game, without an obvious isolated traumatic episode. In addition, he experienced a new left sided headache, fatigue, and difficulty ambulating. He was admitted and an extensive workup was performed. CT and MRI of the head revealed concurrent intracranial and spinal subdural hematomas (SDH. Clinical workup did not reveal any evidence of coagulopathy or predisposing vascular lesions. Spinal SDH is an uncommon condition whose concurrence with intracranial SDH is an even greater clinical rarity. We suggest that our case represents an acute on chronic intracranial SDH with rebleeding, membrane rupture, and symptomatic redistribution of hematoma to the spinal subdural space.

    Hypernatremia has been causally linked with subdural hematoma (SDH), but more recently this has been called into question. Conversely, there is a well-established link between SDH and injury. We wish to examine the evidence base that hypernatremia in infants and young children causes SDH.We present 2 cases of children with severe hypernatremia whose intracranial contents were assessed by imaging in the first case and postmortem examination in the second. Neither demonstrated SDH. The first case was important as the hypernatremia was iatrogenic occurring in a controlled hospital environment.We also searched the literature from 1950 to 2007, collecting data on all reported cases of hypernatremia in children younger than 7 years whose intracranial contents were examined by imaging, surgery, and/or postmortem examination. Of 124 cases reported in 31 articles, 112 cases developed hypernatremia in the community, and 12 in the hospital. Subdural hematoma was demonstrated in 7 cases, all of which had developed hypernatremia in the community under circumstances that would make it difficult to exclude nonaccidental injury. None of the 12 cases that developed hypernatremia in a controlled hospital environment had SDH.The evidence base supporting the hypothesis that hypernatremia causes SDH is poor, depending on isolated reports with uncertain histories.

    Full Text Available Subdural hematoma (SDH is a common condition in infancy and young children with a poor prognostic. The more studies related SDH with nonaccidental injury. With the aim to identify the characteristics of SDH in infants below 1 year, a retrospective study of infants below 1 year diagnosed as subdural hematoma who were admitted to PICU Hasan Sadikin General Hospital from Januari 2000 to Desember 2003 has been conducted. Infants less than 1 month and SDH developed after neurosurgery intervention were excluded. Fourteen infants met the inclusion criteria's, consisted of 5 (36% girls and 9 (64% boys, most of them were on 1 month of age (57%. Anemia was found on all cases, thrombocyte normal except in 1 case thrombocytopenia (53,000/mm3. PT prolonged in 9 (100% cases and PTT in 5 (56% from 9 cases. Bilirubin total/direct elevated in 4 (80% from 5 cases, SGOT/SGPT elevated in 5 (83% from 6 cases. From 11 cases, 9 (82% cases were IgG anti-CMV positive and 6 (55% cases were IgM anti CMV positive. Conclusions, SDH can be caused by various etiologies, thus a comprehensive examinations to exclude child abuse are needed. The role of CMV infection should be considered as one of SDH etiology.

    Kawasaki disease is an acute, febrile, self-limiting, inflammatory systemic vasculitis seen in early childhood, most commonly in those below 5 years of age. In Kawasaki disease, the coronary arteries are most commonly affected, which may lead to asymptomatic coronary artery ectasia or formation of an aneurysm. Paroxysmal supraventricular tachycardia(PSVT) is a severe and rare cardiovascular complication of Kawasaki disease. A case of Kawasaki disease presenting with unusual findings, including subdural effusion and PSVT is reported. This is a 4-month-10-day-old boy presents with anterior fontanelle bulging and moderate bilateral subdural effusion at the acute stage of Kawasaki disease and PSVT at the subacute stage of Kawasaki disease. The subdural effusion was resolution after intravenous immunoglobulin(IVIG) administration. And the PSVT was subsided after administered 3 doses of adenosine, 1 dose of amiodarone loading and Propranolol twice per day use. At 1-year follow-up has made a complete recovery with no arrhythmia episodes, developmental effects or abnormal neurologic findings. Subdural effusion in the acute stage of Kawasaki disease may be an inflammatory response. It may resolves spontaneously after anti-inflammatory treatment such as IVIG infusion. PSVT is a severe cardiovascular complication of Kawasaki disease. In those who taking aspirin, we need to carefully observe the heart rhythm and PSVT side effects, especially in the first month.

    To develop a method for the coregistration of digital photographs of the human cortex with head magnetic resonance imaging (MRI) scans for invasive diagnostics and resective neocortical epilepsy surgery. Six chronically epileptic patients (two women, four men; mean age, 34 yr; age range, 20-43 yr) underwent preoperative three-dimensional (3D) T1-weighted MRI scans. Digital photographs of the exposed cortex were taken during implantation of subdural grid electrodes. Rendering software (Analyze 3.1; Biomedical Imaging Resource, Mayo Foundation, Rochester, MN) was used to create an MRI-based 3D model of the brain surface. Digital photographs were manually coregistered with the brain surface MRI model using the registration tool in the Analyze software. By matching the digital photograph and the brain surface model, the position of the subdural electrodes was integrated into the coordinate system of the preoperatively acquired 3D MRI dataset. In all patients, the position of the labeled electrode contacts in relation to the cortical anatomy could be visualized on the 3D models of the cortical surface. At the time of resection, the resulting image of the coregistration process provides a realistic view of the cortex and the position of the subdural electrode. The coregistration of digital photographs of the brain cortex with the results of 3D MRI data sets is possible. This allows for identification of anatomic details underlying the subdural grid electrodes and enhances the orientation of the surgeon.

    Full Text Available "nGerminal matrix-intraventricular hemorrhage (IVH is the most common variety of neonatal intracranial hemorrhage and is characteristics of the premature infant. The importance of the lesion relates not only to its high incidence but to their attendant complications (IC: hydrocephalus. Brain sonography is the procedure of choice in diagnosis of germinal matrix- intraventricular hemorrhage and hydrocephalus. In this study we have used brain sonography for detection of intraventricular hemorrhage and post hemorrhagic hydrocephalus and their incidences. The studied population was consisted of premature neonate (birth weight equal or less than 1500g and gestational age equal or less than 37 weeks who admitted in Mofid Hospital NICU (Tehran, Iran during a one year period. For all neonate (including criteria brain sonography in first week of life was done and in presence of IVH, serial Brain sonography was done weekly for detection of hydrocephalus. A total of 57 neonate entered the study. Intraventicular-germinal matrix hemorrhage was seen in 64.4% (35 patients. Forty percent of patients with intraventricular-germinal matrix hemorrhage had grade I, 11% grade II, 25.7% grade III, 2.8% grade VI. Hydrocephalus was detected in 20 percent of patients who had intraventricular-germinal matrix hemorrhage. That incidence of IVH in our study in comparison with other area and situation is higher. Hydrocephaly had direct relation with severity of IVH. This shows that with control of risk factor of IVH, we can control Post hemorrhagic hydrocephalus.

    Macrophages are an inherent component of the dura mater, and can be characterised in cases of subdural hematoma (SDH) by their progressive and varying accumulation within areas of damage. Gross and histological methods used to determine the age of SDH are inexact. These are in part due to the active nature of such lesions and the diverse manner in which trauma victims respond to injury. Correct diagnosis has obvious medico-legal implications. However, there is as yet no specific diagnostic method that allows the age of SDH to be reliably determined. This study investigated the progressive and orderly pattern of reactivity of resident and infiltrating dural macrophages that occurs in response to injury associated with SDH. 26 postmortem cases of traumatic SDH were examined with survival times (onset of trauma to death) ranging from a few hours and up to 31 days. Macrophage reactivity associated with the dura mater and the underlying hematoma was determined using CD68 and MHC class II immunohistochemistry and the qualitative and quantitative findings compared with the presence of iron detected using conventional Perl's Prussian blue method. The results show that CD68 and MHC class II are differentially expressed within the dura mater and hematoma in SDH, and that the expression of MHC class II is markedly upregulated in the inner aspect of the dura mater within the initial 24 hours following injury. CD68 expression can be detected quantitatively in the hematoma, 24-48 hours after SDH, and within the dura following this period. Linear regression analysis further revealed a significant and positive association between the expression of MHC class II or CD68 antigens and the progressive survival of SDH up to 31 days post-injury, which was not seen with Perl's histochemical method. The expression of MHC class II antigen was a distinguishing, and quantifiable feature particularly localized within the inner aspect of the dura from a very early stage in the progression of

    Mathematical formulae are commonly used to estimate intra-cranial haematoma volume. Such formulae tacitly assume an ellipsoid geometrical morphology. Recently, the 'XYZ/2' formula has been validated and recommended for chronic subdural haematoma (CSDH) volumetric estimation. We aimed to assess the precision and accuracy of mathematical formulae specifically in estimating CSDH volume, and to determine typical CSDH 3-D morphology. Three extant formulae ('XYZ/2', 'π/6·XYZ' and '2/3S·h') were compared against computer-assisted 3D volumetric analysis as Gold standard in CTs where CSDH sufficiently contrasted with brain. Scatter-plots (n=45) indicated that, in contrast to prior reports, all formulae most commonly over-estimated CSDH volume against 3-D Gold standard ('2/3S·h': 44.4%, 'XYZ/2': 48.84% and 'π/6·XYZ': 55.6%). With all formulae, imprecision increased with increased CSDH volume: in particular, with clinically-relevant CSDH volumes (i.e. >50ml). Deviations >10% of equivalence were observed in 60% of estimates for 2/3S·h, 77.8% for 'XYZ/2' and 84.4% for 'π/6·XYZ'. The maximum error for 'XYZ/2' was 142.3% of a clinically-relevant volume. Three-D simulations revealed that only 4/45 (9%) CSDH remotely conformed to ellipsoid geometrical morphology. Most (41/45, 91%) demonstrated highly irregular morphology neither recognisable as ellipsoid, nor as any other regular/non-regular geometric solid. Mathematical formulae, including 'XYZ/2', most commonly proved inaccurate and imprecise when applied to CSDH. In contrast to prior studies, all most commonly over-estimated CSDH volume. Imprecision increased with CSDH volume, and was maximal with clinically-relevant CSDH volumes. Errors most commonly related to a flawed assumption regarding ellipsoid 3-D CSDH morphology. The validity of mean comparisons, or correlation analyses, used in prior studies is questioned. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Brain tumors with concomitant intracerebral hemorrhage are rarely encountered. Hemorrhage as the initial presentation of a brain tumour may pose some diagnostic problems, especially if the tumour is small or the hemorrhage is abundant. We present a 47-year-old man who admitted to the emergency department with sudden onset headache, right blurred vision and gait disturbance. A non-contrast cranial computerized tomography scan performed immediately after his admission revealed a well circumscribed right occipitoparietal haematoma with intense peripheral edema causing compression of the ipsilateral ventricles. On 6th hour of his admission the patient%u2019s neurological status deteriorated and he subsequently underwent emergent craniotomy and microsurgical evacuation of the haematoma. The histopathological examination of the mass was consistent with a glioblastoma multiforme. Neoplasms may be hidden behind each case of spontaneous intracerebral hemorrhage. Histological sampling and investigation is mandatory in the presence of preoperative radiological features suggesting a neoplasm.

  14. Curbing Inflammation in hemorrhagic trauma: a review

    Directory of Open Access Journals (Sweden)

    MAURICIO GODINHO

    Full Text Available Trauma is one of the world's leading causes of death within the first 40 years of life and thus a significant health problem. Trauma accounts for nearly a third of the lost years of productive life before 65 years of age and is associated with infection, hemorrhagic shock, reperfusion syndrome, and inflammation. The control of hemorrhage, coagulopathy, optimal use of blood products, balancing hypo and hyperperfusion, and hemostatic resuscitation improve survival in cases of trauma with massive hemorrhage. This review discusses inflammation in the context of trauma-associated hemorrhagic shock. When one considers the known immunomodulatory effects of traumatic injury, allogeneic blood transfusion, and the overlap between patient populations, it is surprising that so few studies have assessed their combined effects on immune function. We also discuss the relative benefits of curbing inflammation rather than attempting to prevent it.

    Full Text Available BACKGROUND: Retinal hemorrhages have been described as a component of high altitude retinopathy (HAR in association with altitude illness. In this prospective high altitude study, we aimed to gain new insights into the pathophysiology of HAR and explored whether HAR could be a valid early indicator of altitude illness. METHODOLOGY/PRINCIPAL FINDINGS: 28 mountaineers were randomly assigned to two ascent profiles during a research expedition to Mt. Muztagh Ata (7546 m/24,751 ft. Digital fundus photographs were taken prior to expedition at 490 m (1,607 ft, during expedition at 4497 m (14,750 ft = base camp, 5533 m (18,148 ft, 6265 m (20,549 ft, 6865 m (22,517 ft and 4.5 months thereafter at 490 m. Number, size and time of occurrence of hemorrhages were recorded. Oxygen saturation (SpO₂ and hematocrit were also assessed. 79% of all climbers exhibited retinal hemorrhages during the expedition. Number and area of retinal bleeding increased moderately to medium altitudes (6265 m. Most retinal hemorrhages were detected after return to base camp from a high altitude. No post-expeditional ophthalmic sequelae were detected. Significant negative (SpO₂ Beta: -0.4, p<0.001 and positive (hematocrit Beta: 0.2, p = 0.002, time at altitude Beta: 0.33, p = 0.003 correlations with hemorrhages were found. CONCLUSIONS/SIGNIFICANCE: When closely examined, a very large amount of climbers exhibit retinal hemorrhages during exposure to high altitudes. The incidence of retinal hemorrhages may be greater than previously appreciated as a definite time lag was observed between highest altitude reached and development of retinal bleeding. Retinal hemorrhages should not be considered warning signs of impending severe altitude illness due to their delayed appearance.

    Experimental Junin virus infection of a New World primate, Callithrix jacchus, was evaluated. The virus produced anorexia, loss of weight, thrombocytopenia, leukopenia, and hemorrhagic and neurological symptoms and terminated in death. Virus was recovered from urine, blood samples and all tissues taken at autopsy. These preliminary observations show that several aspects of the experimental disease in C. jacchus are quite similar to severe natural Argentine hemorrhagic fever of man.

  1. Impaired Fracture Healing after Hemorrhagic Shock

    Directory of Open Access Journals (Sweden)

    Philipp Lichte

    2015-01-01

    Full Text Available Impaired fracture healing can occur in severely injured patients with hemorrhagic shock due to decreased soft tissue perfusion after trauma. We investigated the effects of fracture healing in a standardized pressure controlled hemorrhagic shock model in mice, to test the hypothesis that bleeding is relevant in the bone healing response. Male C57/BL6 mice were subjected to a closed femoral shaft fracture stabilized by intramedullary nailing. One group was additionally subjected to pressure controlled hemorrhagic shock (HS, mean arterial pressure (MAP of 35 mmHg for 90 minutes. Serum cytokines (IL-6, KC, MCP-1, and TNF-α were analyzed 6 hours after shock. Fracture healing was assessed 21 days after fracture. Hemorrhagic shock is associated with a significant increase in serum inflammatory cytokines in the early phase. Histologic analysis demonstrated a significantly decreased number of osteoclasts, a decrease in bone quality, and more cartilage islands after hemorrhagic shock. μCT analysis showed a trend towards decreased bone tissue mineral density in the HS group. Mechanical testing revealed no difference in tensile failure. Our results suggest a delay in fracture healing after hemorrhagic shock. This may be due to significantly diminished osteoclast recruitment. The exact mechanisms should be studied further, particularly during earlier stages of fracture healing.

    Full Text Available Dengue is a viral disease that is mediated by a mosquito, which causes morbidity and mortality. Viruses can increase vascular permeability which can lead to hemorrhagic diathesis or disseminated intravascular coagulation (DIC known as dengue hemorrhagic fever (DHF. In Indonesia, dengue hemorrhagic fever (DHF are caused by dengue virus infection which was found to be endemic accompanied by an explosion of extraordinary events that appear at various specified period. The diagnosis of dengue is determined based on the criteria of the World Health Organization (WHO, 1999, which are sudden high fever accompanied by a marked tendency to hemorrhage positive tourniquet test, petechiae, ecchymosis, purpura, mucosal hemorrhagic, hematemesis or melena and thrombocytopenia. The problem that still exists today is the mechanism of thrombocytopenia in patients with varying degrees of dengue involving levels of vWF (von Willebrand factor and prostaglandin I2 (PGI2 can not be explained. The mechanism of hemorrhagic in dengue virus infections acquired as a result of thrombocytopenia, platelet disfunction decreased coagulation factors, vasculopathy with endothelial injury and disseminated intravascular coagulation (DIC.

Stroke was divided into is chemic and hemorrhagic until the end of the Qing dynasty. In 1997, Terminology of Traditional Chinese Medicine Treatment-Disease Part of National Standard formally included the term hemorrhagic stroke. Before 1950s-1960s, the pathogenesis emphasizes the up-stirring of liver, the adverse-rising of both blood and qi. A proper remedy should to subdue the liver yang, calm down the endopathic wind and clear heat. Since 1970s, it has been considered that the disorder is closely related with the spleen and stomach. The focal pathogenesis was blocked passage of the middle jiao, disorder of qi in ascending and descending and the abnormal flow of qi and blood. Since 1980s, it was claimed that hemorrhagic stroke belongs to blood syndrome of TCM. The vital pathogenesis was accumulation of blood stasis in acute stage of hemorrhagic stroke. The key point of therapeutical method was to promote blood circulation to remove blood stasis. In recent years, the theories of endogenous toxic factor, consumption, yin and yang syndrome, and the therapeutical method of antidote, assisting the vital qi, especially the development of common therapeutical methods were developed, with an abundance of differential diagnosis and treatment in hemorrhagic stroke.

    The purpose of study A was to assess the effectiveness of vitrectomy for Terson syndrome. The purpose of study B was to determine the incidence and significance of vitreous hemorrhage in patients with subarachnoid hemorrhage. Study A is a retrospective review of case series. Study B is a prospective study. Study A examined a consecutive series of 4 children (7 eyes) and 23 adults (26 eyes). Study B examined a consecutive series of 100 patients. Subjects in study A underwent pars plana vitrectomy for dense vitreous hemorrhage following intracranial hemorrhage. In study B, ophthalmoscopic examination of patients undergoing neurosurgery for ruptured cerebral aneurysms was used. In study A, the extent and rapidity of visual recovery and intraoperative and postoperative complications were examined. In study B, the incidences of intraocular hemorrhage and Terson syndrome in the cohort and the significance of the presence of vitreous hemorrhage in patients with subarachnoid hemorrhage were examined. Study A: There was substantial and rapid visual improvement in 25 of the 26 eyes (96%) of the adult patients, with 21 eyes (81%) achieving > or = 20/30 final visual acuity. Only limited improvement was achieved in children's eyes (Terson syndrome was 8%. All patients with Terson syndrome and 89% of the patients with other types of intraocular hemorrhage had a history of coma compared with 46% of those without intraocular hemorrhage (P = 0.0003). Vitreous hemorrhage in patients surviving subarachnoid hemorrhage appears to be more common than previously thought, underscoring the need for routine funduscopic screening. Surgical intervention is highly effective in hastening visual rehabilitation of adults with Terson syndrome. The less encouraging results in infants may be due to amblyopia or direct brain damage caused by the cerebrovascular incident.

    Intraplaque hemorrhage is considered a leading parameter of carotid plaque vulnerability. Our purpose was to assess the CT characteristics of intraplaque hemorrhage with histopathologic correlation to identify features that allow for confirming or ruling out the intraplaque hemorrhage. This retrospective study included 91 patients (67 men; median age, 65 ± 7 years; age range, 41-83 years) who underwent CT angiography and carotid endarterectomy from March 2010 to May 2013. Histopathologic analysis was performed for the tissue characterization and identification of intraplaque hemorrhage. Two observers assessed the plaque's attenuation values by using an ROI (≥ 1 and ≤2 mm2). Receiver operating characteristic curve, Mann-Whitney, and Wilcoxon analyses were performed. A total of 169 slices were assessed (59 intraplaque hemorrhage, 63 lipid-rich necrotic core, and 47 fibrous); the average values of the intraplaque hemorrhage, lipid-rich necrotic core, and fibrous tissue were 17.475 Hounsfield units (HU) and 18.407 HU, 39.476 HU and 48.048 HU, and 91.66 HU and 93.128 HU, respectively, before and after the administration of contrast medium. The Mann-Whitney test showed a statistically significant difference of HU values both in basal and after the administration of contrast material phase. Receiver operating characteristic analysis showed a statistical association between intraplaque hemorrhage and low HU values, and a threshold of 25 HU demonstrated the presence of intraplaque hemorrhage with a sensitivity and specificity of 93.22% and 92.73%, respectively. The Wilcoxon test showed that the attenuation of the plaque before and after administration of contrast material is different (intraplaque hemorrhage, lipid-rich necrotic core, and fibrous tissue had P values of .006, .0001, and .018, respectively). The results of this preliminary study suggest that CT can be used to identify the presence of intraplaque hemorrhage according to the attenuation. A threshold of 25

    Conclusion: For routine neurosurgical practice, these entities are extremely rare; and hence a working knowledge is very essential for appropriate & timely management notwithstanding the neurosurgical desire to rule out the compressive lesions first. Neurological status deterioration may be halted with timely institution of appropriate chemotherapy. In the extensive literature review in pubmed, this may be only the 1st case of MPAL with extramedullary neurological manifestation, at the first clinical presentation.

    OBJECTIVE The aims of this study were to evaluate a multiyear experience with subdural evacuating port system (SEPS) placement for chronic subdural hematoma (cSDH) in the intensive care unit at a tertiary neurosurgical center and to compare SEPS placement with bur hole evacuation in the operating room. METHODS All cases of cSDH evacuation were captured over a 7-year period at a tertiary neurosurgical center within an integrated health care delivery system. The authors compared the performance characteristics of SEPS and bur hole placement with respect to recurrence rates, change in recurrence rates over time, complications, length of stay, discharge disposition, and mortality rates. RESULTS A total of 371 SEPS cases and 659 bur hole cases were performed (n = 1030). The use of bedside SEPS placement for cSDH treatment increased over the 7-year period, from 14% to 80% of cases. Reoperation within 6 months was higher for the SEPS (15.6%) than for bur hole drainage (9.1%) across the full 7-year period (p = 0.002). This observed overall difference was due to a higher rate of reoperation during the same hospitalization (7.0% for SEPS vs 3.2% for bur hole; p = 0.008). Over time, as the SEPS procedure became more common and modifications of the SEPS technique were introduced, the rate of in-hospital reoperation after SEPS decreased to 3.3% (p = 0.02 for trend), and the difference between SEPS and bur hole recurrence was no longer significant (p = 0.70). Complications were uncommon and were similar between the groups. CONCLUSIONS Overall performance characteristics of bedside SEPS and bur hole drainage in the operating room were similar. Modifications to the SEPS technique over time were associated with a reduced reoperation rate.

    Patients with traumatic intracranial hemorrhage and mild traumatic brain injury (mTIH) receive broadly variable care which often includes transfer to a trauma center, neurosurgery consultation and ICU admission. However, there may be a low risk cohort of patients who can be managed without utilizing such significant resources. Describe mTIH patients who are at low risk of clinical or radiographic decompensation and can be safely managed in an ED observation unit (EDOU). Retrospective evaluation of patients age≥16, GCS≥13 with ICH on CT. Primary outcomes included clinical/neurologic deterioration, CT worsening or need for neurosurgery. 1185 consecutive patients were studied. 814 were admitted and 371 observed patients (OP) were monitored in the EDOU or discharged from the ED after a period of observation. None of the OP deteriorated clinically. 299 OP (81%) had a single lesion on CT; 72 had mixed lesions. 120 patients had isolated subarachnoid hemorrhage (iSAH) and they did uniformly well. Of the 119 OP who had subdural hematoma (SDH), 6 had worsening CT scans and 3 underwent burr hole drainage procedures as inpatients due to persistent SDH without new deficit. Of the 39 OP who had cerebral contusions, 3 had worsening CT scans and one required NSG admission. No patient returned to the ED with a complication. Follow-up was obtained on 81% of OP. 2 patients with SDH required burr hole procedure >2weeks after discharge. Patients with mTIH, particularly those with iSAH, have very low rates of clinical or radiographic deterioration and may be safe for monitoring in an emergency department observation unit.

    OBJECT: In this paper the authors investigate whether shunt-treated patients with normal-pressure hydrocephalus receiving aspirin therapy are at increased risk of developing subdural hematoma (SDH). METHODS: Records from 80 consecutive patients who had undergone implantation of a cerebrospinal...... fluid shunt for the treatment of normal-pressure hydrocephalus were retrospectively reviewed. RESULTS: Eleven cases of symptomatic SDH occurred, all among patients receiving aspirin or clopidogrel. The 5-year survival estimate was 0.3 (p ...% CI 3.1-53). CONCLUSIONS: Patients on an aspirin therapy regimen have a markedly increased risk of SDH after a shunt has been implanted for the treatment of normal-pressure hydrocephalus. Users of clopidogrel may have an even greater risk....

    The aim of this work was comparison of two algorithms of perfusion computed tomography (PCT) data analysis for evaluation of cerebral microcirculation in the perifocal zone of chronic subdural hematoma (CSDH). Twenty patients with CSDH after polytrauma were included in the study. The same PCT data were assessed quantitatively in cortical brain region beneath the CSDH (zone 1), and in the corresponding contralateral brain hemisphere (zone 2) without and with the use of perfusion calculation mode excluding vascular pixel 'Remote Vessels' (RV); 1st and 2nd analysis method, respectively. Comparison with normal values for perfusion indices in the zone 1 in the 1st analysis method showed a significant (p analysis method) showed no statistically reliable change of perfusion parameters in the microcirculatory blood flow of the 2nd zone. Maintenance of microcirculatory blood flow perfusion reflects the preservation of cerebral blood flow autoregulation in patients with CSDH.

    In 1954, Penfield and Jasper briefly described that percepts of unpleasant odor were elicited by intraoperative electrical stimulation of the olfactory bulb in patients with epilepsy. Since then, few peer-reviewed studies have reported such phenomena elicited by stimulation mapping via subdural electrodes implanted on the ventral surface of the frontal lobe. Here, we determined what types of olfactory hallucinations could be reproduced by such stimulation in children with focal epilepsy. This study included 16 children (age range: 5 to 17 years) who underwent implantation of subdural electrodes to localize the presumed epileptogenic zone and eloquent areas. Pairs of electrodes were electrically stimulated, and clinical responses were observed. In case a patient reported a perception, she/he was asked to describe its nature. We also described the stimulus parameters to elicit a given symptom. Eleven patients reported a perception of smell in response to electrical stimulation while the remaining five did not. Nine patients perceived an unpleasant smell (like bitterness, smoke, or garbage) while two perceived a pleasant smell (like strawberry or good food). Such olfactory hallucinations were induced by stimulation proximal to the olfactory bulb or tract on either hemisphere but not by that of orbitofrontal gyri lateral to the medial orbital sulci. The range of stimulus parameters employed to elicit olfactory hallucinations was comparable to those for other sensorimotor symptoms. Our systematic study of children with epilepsy replicated stimulation-induced olfactory hallucinations. We failed to provide evidence that a positive olfactory perception could be elicited by conventional stimulation of secondary olfactory cortex alone. Copyright © 2012 Elsevier Inc.

    Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described. To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children exam or retinal camera images. A staff pediatric radiologist and radiology resident reviewed the MR images. Retinal hemorrhages were graded by a chief ophthalmology resident on a 12-point scale based on the retinal hemorrhage type, size, location and extent as seen on review of retinal camera images and detailed reports by ophthalmologists. Higher scores indicated increased severity of retinal hemorrhages. There was a statistically significant difference in the median grade of retinal hemorrhage examination between children who had retinal hemorrhage detected on MRI and children who did not have retinal hemorrhage detected on MRI (P = 0.02). When examination grade was categorized as low-grade (1-4), moderate-grade (5-8) or high-grade (>8) hemorrhage, there was a statistically significant association between exam grade and diagnosis based on MRI (P = 0.008). For example, only 14% of children with low-grade retinal hemorrhages were identified on MRI compared to 76% of children with high-grade hemorrhages. MR detection of retinal hemorrhage demonstrated a sensitivity of 61%, specificity of 100%, positive predictive value of 100% and negative predictive value of 63%. Retinal hemorrhage was best seen on the gradient recalled echo (GRE) sequences. MRI using routine brain protocol demonstrated 61% sensitivity and 100% specificity

To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children <2 years old who were seen for head trauma from April 2007 to July 2013 and had both brain MRI and dilated fundoscopic exam or retinal camera images.

    To report the anatomic location of bilateral dome-shaped posterior pole hemorrhages in a patient with Terson syndrome. Case report. We performed bilateral vitrectomy for vitreous hemorrhage in a patient with Terson syndrome. After removal of vitreous hemorrhage, the tissue overlying a large discrete hemorrhage in the posterior pole was removed, and the tissue from one eye was examined histologically. The discrete dome-shaped hemorrhage in the posterior pole was confined to the retina anteriorly by the internal limiting membrane. Large dome-shaped retinal hemorrhages with Terson syndrome can be located beneath the internal limiting membrane of the retina.

    Hemorrhagic cystitis is a challenging clinical entity with limited evidence available to guide treatment. The use of intravesical silver nitrate has been reported, though supporting literature is sparse. Here, we sought to assess outcomes of patients treated with intravesical silver nitrate for refractory hemorrhagic cystitis. We identified nine patients with refractory hemorrhagic cystitis treated at our institution with intravesical silver nitrate between 2000-2015. All patients had failed previous continuous bladder irrigation with normal saline and clot evacuation. Treatment success was defined as requiring no additional therapy beyond normal saline irrigation after silver nitrate instillation prior to hospital discharge. Median patient age was 80 years (IQR 73, 82). Radiation was the most common etiology for hemorrhagic cystitis 89% (8/9). Two patients underwent high dose (0.1%-0.4%) silver nitrate under anesthesia, while the remaining seven were treated with doses from 0.01% to 0.1% via continuous bladder irrigation for a median of 3 days (range 2-4). All nine patients (100%) had persistent hematuria despite intravesical silver nitrate therapy, requiring additional interventions and red blood cell transfusion during the hospitalization. There were no identified complications related to intravesical silver nitrate instillation. Although well tolerated, we found that intravesical silver nitrate was ineffective for bleeding control, suggesting a limited role for this agent in the management of patients with hemorrhagic cystitis.

    We report the case of a young man with sudden onset of diplopia after an upper respiratory tract infection. Based on the first radiological findings acute hemorrhagic leukoencephalitis, a variant of acute disseminated encephalomyelitis, was suspected and treatment with high dose intravenous dexamethasone was started but it was stopped for intolerance. The patient clinically worsened, developing gait instability, ataxia and ophthalmoplegia; brain MRI performed 20 days later showed severe progression of the disease with subependymal dissemination. After brain biopsy of the right temporal lesion the histological diagnosis was glioblastoma. These findings suggest that MRI features of acute hemorrhagic leukoencephalitis may dissimulate the diagnosis of diffuse glioma/glioblastoma. This case underscores the importance of considering diffuse glioma in the differential diagnosis of atypical signs and symptoms of acute hemorrhagic leukoencephalitis and underlines the relevant role of integrating neuroradiologic findings with neuropathology.

    The aim of the present study was to investigate the rate of post-tonsillectomy hemorrhage (PTH) in a single institution and to evaluate the clinical risk factors for PTH. We reviewed the records of 692 patients who underwent tonsillectomy (TE) at Yokohama Minami Kyosai Hospital in Japan. PTH grades were grouped into three categories according to the severity of the hemorrhagic episode: (I) minimal hemorrhage that stopped after noninvasive treatment, (II) hemorrhage requiring treatment with local anesthesia, and (III) hemorrhage requiring reoperation under general anesthesia in the operating room. Clinical risk factors such as sex, age (adults vs. children), TE indication, surgeon's skill level, operative time, ligature type, and duration of antibiotic administration for PTH were investigated. Among the 692 patients, 80 (11.6%) showed PTH, with primary and secondary hemorrhage accounting for 1.6% and 10.0%, respectively. A category III PTH was observed in 18 patients; thus, the overall risk of reoperation was 2.6%. The PTH episode most frequently occurred on postoperative days 5 and 6. The frequency of PTH was significantly higher in male patients and in adults (Pskill was also associated with PTH rate. A stepwise multivariate logistic regression revealed that adult age (odds ratio [OR]=18.9) and male gender (OR=3.78) were the clinical risk factors for PTH. It also revealed that male gender (OR=82065335), adult age (OR=10.6), and surgeon's skill level (OR=7.50) were the clinical risk factors for the category III PTH. The risk of PTH was higher in this report compared with previous reports, which may be associated with the definition of PTH. Clinical risk factors for PTH were adult age and male gender. The surgeon's skill level was an additional risk factor for category III PTH. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  1. Pathogenesis and clinical implications of optic disk hemorrhage in glaucoma.

    Suh, Min Hee; Park, Ki Ho

    2014-01-01

    The association between optic disk hemorrhage and glaucoma has been studied for many years. Recently, randomized clinical trials have confirmed that disk hemorrhage is a risk factor for development and progression of glaucoma. Disk hemorrhage is more commonly detected in open-angle glaucoma with normal tension than in open-angle glaucoma with high tension. Development of disk hemorrhage possibly is associated with the biomechanical properties of the lamina cribrosa and surrounding tissues, including the intraocular pressure (IOP)-cerebrospinal pressure gradient, arterial pressure, and venous pressure. Disk hemorrhage may be a marker of rapid glaucoma progression, in that localized subclinical structural change predisposes to disk hemorrhage, after which subsequent disease progression is accelerated, and recurrent optic disk hemorrhages are related to rapid structural progression of glaucomatous damage. IOP-lowering therapy can be helpful in halting post-hemorrhage glaucoma progression. Copyright © 2014 Elsevier Inc. All rights reserved.

    The purpose of this study was to determine the added value of the perimedullary spinal vein enlargement sign on magnetic resonance imaging (MRI) in distinguishing intradural-extramedullary tumors (IDEMTs) from intramedullary spinal tumors (IMTs). Two hundred and eight consecutive spinal intradural tumors with histopathologic confirmation (21 IMTs, 187 IDEMTs) were enrolled. Two readers blinded to the final pathological diagnosis and clinical data independently assessed the venous enlargement sign to determine the agreement between them and jointly distinguished IDEMTs from IMTs according to the common MRI findings. Sensitivity, specificity, and accuracy for the diagnosis of IDEMTs were calculated for the common MRI findings, vein enlargement sign, and a combination of both. Intraobserver agreement and interobserver agreement for both readers was excellent. The sensitivity, specificity, and accuracy of common MRI findings for differentiating IDEMTs from IMTs were 83.4, 95.2, and 89.3 %, respectively. Thirty-one IDEMTs were mistakenly diagnosed as IMTs, in which seven were cases with vein enlargement signs. By applying the vein enlargement sign to the common MRI findings, the specificity remained at 95.2 %, while the sensitivity improved to 89.3 % and the accuracy increased to 92.3 %. The spinal perimedullary vein enlargement sign is useful in assessing intradural tumors and to differentiate IDEMTs from IMTs. (orig.)

    Full Text Available Background Extramedullary alignment is a well established surgical technique during total knee replacement. There are different methods to achieve accuracy but variability is quite extensive. To attain uniformity in the surgical technique we have been using the tibialis tendon to align our resection guide. This may prove to be a useful aid for surgeons during knee replacement surgery. Objectives The purpose of our study was to establish if tibialis anterior tendon represents the centre of ankle joint and if it could be used as an anatomical reference for alignment during knee replacement. Methods We designed a retrospective radiological cohort study. We studied sixty MRI scans of normal ankles. The centre of ankle joint was marked as a bisection point of the intermalleolar line at the level of superior surface of the talus. A line was drawn connecting the centre of Achilles tendon to the ankle centre and this was extended anteriorly. This line was found to have a constant relation to the ankle centre and it would simulate the positioning of the standard alignment device used. Results The tibialis anterior tendon lies less than 3mm medial to the ankle centre in the frontal plane. Conclusions We conclude that the tibialis anterior tendon can be used during knee replacement surgery as an accurate alignment guide.

    Full Text Available Malaria remains a significant public health problem of the tropical world. Falciparum malaria is most prevalent in the sub-Saharan African region, which harbors about 90% of all malaria cases and fatalities globally. Infection by the falciparum species often manifests with a spectrum of multi-organ complications (eg, cerebral malaria, some of which are life-threatening. Spontaneous subdural empyema is a very rare complication of cerebral malaria that portends a very poor prognosis unless diagnosed and treated promptly. We report a case of spontaneous subdural empyema in a 58-year-old woman from Tanzania who presented with high-grade fever, decreased urine output, and altered sensorium.

    Full Text Available The surgical treatment of intracranial aneurysms by clipping is recognized as effective and definitive. However some cases that suffered a new subarachnoid hemorrhage (SAH some time after they were submitted to aneurysm clipping have raised doubts about the concept of "cure"after this treatment. Eleven patients previously submitted to aneurysm clipping who presented a new SAH were analyzed. The time elapsed from surgery to SAH varied from 3 to 10 years. After SAH four patients had a poor outcome. The new episode of SAH occurred due to intrinsic factors of the cerebral vasculature: 1. a weak point of the vessel wall near the previous aneurysm, 2. a weak point of another vessel far from the previous aneurysm, 3. a previous infundibular dilation of the posterior communicating artery; and due to technical problems: 1. aneurysm not identified during the previous treatment, 2. aneurysm deliberately left untreated, 3. persistence of the aneurysm due to inappropriate surgery, 4. persistency of part of the aneurysm neck after clipping and 5. slipping of the clip from the neck of the aneurysm. The measures to prevent new SAH after surgery start with adequate preoperative angiographic studies, a careful inspection of the position of the clip and emptying of the aneurysm. Early angiography studies may reveal a persistent neck and later ones may reveal newly developed aneurysms. In conclusion, SAH after aneurysm clipping is a late and severe phenomenon and the concept of "cure" after this surgery should be interpreted with caution.O tratamento cirúrgico dos aneurismas cerebrais através de sua clipagem é reconhecido como eficaz e definitivo. Entretanto alguns casos sofrem nova hemorragia algum tempo após a cirurgia, deixando dúvidas sobre a "cura" pelo tratamento.

    To know the arbovirus causing hemorrhagic fever in patients at the Mexican Institute of Social Security. A follow-up study was made in patients with probable diagnosis of hemorrhagic dengue. Blood samples were taken to look for dengue fever, yellow fever and San Luis, Tonate and Mayaro encephalitis viruses. Frequencies and proportions of the interest variables were analyzed. 35 patients were studied. Isolation and PCR results of the 13 samples were negative in 12 of them and positive to denguevirus-3 in one of them. The determination of IgM was positive for dengue fever in 25 cases; 2 were positive to Mayaro virus and 8 were negative to what was looked for. Hemorrhages and thrombocytopenia were more frequent in patients infected with dengue and Mayaro viruses; jaundice and encephalopathy were more frequent in the latter, and renal dysfunction, in patients with a negative result. Evolution was satisfactory in all cases, except for one (Mayaro), which presented hemorrhages, thrombocytopenia, jaundice and encephalopathy that lead to death. The results show the risk of appearance and dissemination of several vector-born diseases in Mexico. Thus, they require intensive epidemiological surveillance to identify them and to know their real occurrence and specific clinical profile.

    Snake venom metalloproteinases are important toxins that play fundamental roles during envenomation. They share a structurally similar catalytic domain, but with diverse hemorrhagic capabilities. To understand the structural basis for this difference, we build and compare two dynamical models, one for the hemorrhagic atroxlysin-I from Bothrops atrox and the other for the non-hemorraghic leucurolysin-a from Bothrops leucurus. The analysis of the extended molecular dynamics simulations shows some changes in the local structure, flexibility and surface determinants that can contribute to explain the different hemorrhagic activity of the two enzymes. In agreement with previous results, the long Ω-loop (from residue 149 to 177) has a larger mobility in the hemorrhagic protein. In addition, we find some potentially-relevant differences at the base of the S1' pocket, what may be interesting for the structure-based design of new anti-venom agents. However, the sharpest differences in the computational models of atroxlysin-I and leucurolysin-a are observed in the surface electrostatic potential around the active site region, suggesting thus that the hemorrhagic versus non-hemorrhagic activity is probably determined by protein surface determinants.

    Hemorrhagic events associated with cerebral paragonimiasis are not rare, especially in children and adolescents; however, angiographic evidence of cerebrovascular involvement has not been reported. The authors describe angiographic abnormalities of the cerebral arteries seen in 2 children in whom cerebral paragonimiasis was associated with hemorrhagic stroke. The patients presented with acute intracerebral and subarachnoid hemorrhage. Angiography revealed a beaded appearance and long segmental narrowing of arteries, consistent with arteritis. In both patients, involved vessels were seen in the area of the hemorrhage. The vascular changes and the hemorrhage, together with new lesions that developed close to the hemorrhage and improved after praziquantel treatment, were attributed to paragonimiasis. Further study of the frequency and mechanism of hemorrhagic cerebrovascular complications associated with cerebral paragonimiasis is needed.

    Full Text Available Inconsistency of the current classification of cerebral intraventricular hemorrhages is discussed in the article. The author explains divergence of including of the subependymal (1st stage and intracerebral (4th stage hemorrhages into this classification. A new classification of cerebral intraventricular hemorrhages including their origin, phases and stages is offered. The most common origin of intraventricular hemorrhages is subependymal hemorrhage (82,2%. Two phases of hemorrhage were distinguished: bleeding phase and resorption phase. Stages of intraventricular hemorrhages reflecting the blood movement after the onset of bleeding are the following: 1 — infill of the up to ½ of the lateral ventricles without their enlargement; 2 — infill of more than ½ of the lateral ventricles with their enlargement; 3 — infill of the IV ventricle, of the cerebellomedullary cistern and its dislocation into the subarachnoid space of the cerebellum, pons varolii, medulla oblongata and spinal cord.

    The clinical features of thalamic hemorrhage in terms of localization are of great interest in many studies. To better understand the relationship between the localization of thalamic hemorrhage and clinical features. we evaluated the characteristics of patients with four different topographic types of thalamic hemorrhage. We prospectively studied 100 patients with thalamic hemorrhage who were admitted consecutively to our primary care unit. We divided them into two groups according to large (> 2 cm in diameter and/or > 4 mL in volume) and small thalamic hemorrhage. Four topographic subgroups (large and small) were compared to identify clinical syndromes associated with distinct lesion locations. All patients with posterolateral thalamic hemorrhage had severe sensorimotor deficit. Neuropsychological disturbances in patients with posterolateral thalamic hemorrhage were prominent, with primarily transcortical aphasia in those with left-sided lesions and hemineglect and anosognosia in those with right-sided lesions. Several variants of vertical gaze dysfunction, skew ocular deviation, gaze preference toward the site of the lesion, and miotic pupils were frequent in posterolateral thalamic hemorrhage, particularly in the large type. Patients with small and large anterolateral thalamic hemorrhage were characterized by severe motor and sensory deficits; language and oculomotor disturbances were also observed, although less frequently than in posterolateral hemorrhage. Sensorimotor deficits were observed in patients with medial thalamic hemorrhage (moderate in small hemorrhages and severe in large hemorrhages because of involvement of the adjacent internal capsule). Language disturbances in patients with left-sided lesions and neglect in patients with right-sided lesions were seen only in large medial thalamic hemorrhage. Dorsal thalamic hemorrhage was rare and characterized by mild and transient sensorimotor disturbances. Among patients with dorsal thalamic hemorrhages

    The objective of this study was to characterize risk for and temporal trends in postpartum hemorrhage across hospitals with different delivery volumes. This study used the Nationwide Inpatient Sample (NIS) to characterize risk for postpartum hemorrhage from 1998 to 2011. Hospitals were classified as having either low, moderate or high delivery volume (≤1000, 1001 to 2000, >2000 deliveries per year, respectively). The primary outcomes included postpartum hemorrhage, transfusion, and related severe maternal morbidity. Adjusted models were created to assess factors associated with hemorrhage and transfusion. Of 55,140,088 deliveries included for analysis 1,512,212 (2.7%) had a diagnosis of postpartum hemorrhage and 361,081 (0.7%) received transfusion. Risk for morbidity and transfusion increased over the study period, while the rate of hemorrhage was stable ranging from 2.5 to 2.9%. After adjustment, hospital volume was not a major risk factor for transfusion or hemorrhage. While obstetric volume does not appear to be a major risk factor for either transfusion or hemorrhage, given that transfusion and hemorrhage-related maternal morbidity are increasing across hospital volume categories, there is an urgent need to improve obstetrical care for postpartum hemorrhage. Those risk factors are able to discriminate women at increased risk supports routine use of hemorrhage risk assessment.

    Chronic subdural hematoma (CSDH) is sometimes refractory, and this is troublesome for neurosurgeons. Although many studies have reported risk factors or treatments in efforts to prevent recurrence, those have focused on single recurrence, and few cumulative data are available to analyze refractory CSDH. We defined refractory CSDH as ≥2 recurrences, then analyzed and compared clinical factors between patients with single recurrence and those with refractory CSDH in a cohort study, to clarify whether patients with refractory CSDH experience different or more risk factors than patients with single recurrence, and whether burr-hole irrigation with closed-system drainage reduces refractory CSDH. Seventy-five patients had at least 1 recurrence, with single recurrence in 62 patients and ≥2 recurrences in 13 patients. In comparing clinical characteristics, patients with refractory CSDH were significantly younger (P = 0.04) and showed shorter interval to first recurrence (P refractory CSDH (P = 0.02). Multivariate logistic regression analysis identified first recurrence interval refractory CSDH. On the other hand, burr-hole irrigation with closed-system drainage did not reduce refractory CSDH. When patients with risk factors for refractory CSDH experience recurrence, alternative surgical procedures may be considered as the second surgery, because burr-hole irrigation with closed-system drainage did not reduce refractory CSDH in our study.

    Lowering the length of stay (LOS) is thought to potentially decrease hospital costs and is a metric commonly used to manage capacity. Patients with epilepsy undergoing intracranial electrode monitoring may have longer LOS because the time to seizure is difficult to predict or control. This study investigates the effect of economic implications of increased LOS in patients undergoing invasive electrode monitoring for epilepsy. We retrospectively collected and analyzed patient data for 76 patients who underwent invasive monitoring with either subdural grid (SDG) implantation or stereoelectroencephalography (SEEG) over 2 years at our institution. Data points collected included invasive electrode type, LOS, profit margin, contribution margins, insurance type, and complication rates. LOS correlated positively with both profit and contribution margins, meaning that as LOS increased, both the profit and contribution margins rose, and there was a low rate of complications in this patient group. This relationship was seen across a variety of insurance providers. These data suggest that LOS may not be the best metric to assess invasive monitoring patients (i.e., SEEG or SDG), and increased LOS does not necessarily equate with lower or negative institutional financial gain. Further research into LOS should focus on specific specialties, as each may differ in terms of financial implications. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

After the initial diagnosis of SVT with history and neurological examination findings MRV taken and consistend with thrombus signal change. Dural sinus thrombosis with secondary venous hypertension may lead to SAH into the subarachnoid space due to the rupture of fragile, thin-walled cortical veins. Patients with non-traumatic, non-aneurysmal and non-perimesencephalic subaracnoid hemorrhage tend to have clots circumscribed along the cortical convexity, a condition referred as acute cortical SAH. CVT is a potential cause of cortical SAH. This case; SAH may be the first sign of SVT and especially SVT must do in etiologic research without the involvement of the basal sisterna in cases of SAH.

    Crimean-Congo hemorrhagic fever (CCHF) is a pathogenic tick-borne disease caused by a single-stranded negative-sense RNA virus classified within the Nairovirus genus of the family Bunyaviridae. Cases of CCHF have been registered in Tajikistan since the disease was first brought to medical attention in 1944. However, historical Tajik manuscripts describe the features of hemorrhagic fever associated with ticks, indicating that the disease might have been known in this region for many years before it was officially characterized. Here we review the historical context of CCHF in Tajikistan, much of which has been described over several decades in the Russian literature, and include reports of recent outbreaks in Tajikistan.

    Full Text Available Crimean Congo hemorrhagic fever (CCHF is one of the deadly hemorrhagic fevers that are endemic in Africa, Asia, Eastern Europe, and the Middle East. It is a tick-borne zoonotic viral disease caused by CCHF virus of genus Nairovirus (family Bunyaviridae. CCHF not only forms an important public health threat but has a significant effect on the healthcare personnel, especially in resource-poor countries. India was always a potentially endemic area until an outbreak hit parts of Gujarat, taking four lives including the treating medical team. The current review is an attempt to summarize the updated knowledge on the disease particularly in modern era, with special emphasis on nosocomial infections. The knowledge about the disease may help answer certain questions regarding entry of virus in India and future threat to community.

    Full Text Available Breaking the human-to-human transmission cycle remains the cornerstone of infection control during filoviral (Ebola and Marburg hemorrhagic fever outbreaks. This requires effective identification and isolation of cases, timely contact tracing and monitoring, proper usage of barrier personal protection gear by health workers, and safely conducted burials. Solely implementing these measures is insufficient for infection control; control efforts must be culturally sensitive and conducted in a transparent manner to promote the necessary trust between the community and infection control team in order to succeed. This article provides a review of the literature on infection control during filoviral hemorrhagic fever outbreaks focusing on outbreaks in a developing setting and lessons learned from previous outbreaks. The primary search database used to review the literature was PUBMED, the National Library of Medicine website.

  10. Optic disc hemorrhage in glaucoma: pathophysiology and prognostic significance.

    Kim, Ko Eun; Park, Ki Ho

    2017-03-01

    This article reviews the recent findings with regard to the pathophysiology and clinical significance of optic disc hemorrhage in glaucoma. Even though the pathophysiology of disc hemorrhage has been investigated in depth, its underlying mechanism remains unclear. The key disc hemorrhage mechanisms currently under discussion are mechanical vascular disruption and associated vascular susceptibilities. Recent technical advances in spectral-domain optical coherence tomography have yielded more compelling evidence of mechanical vascular disruption behind the pathogenesis of disc hemorrhage in glaucoma. Studies show that disc hemorrhage is associated with structural and functional glaucoma progression. Furthermore, recent findings suggest that disc hemorrhage can have different significances according to its location, recurrence, and associated underlying mechanism. The underlying mechanism of disc hemorrhage is complex like that of glaucoma. The ongoing controversy respecting the role of disc hemorrhage as a risk factor for glaucoma progression notwithstanding, special attention entailing closer follow-up and/or treatment escalation is recommended for patients with disc hemorrhage. Further studies investigating the unrevealed pathogenesis of disc hemorrhage and its prognostic value in glaucoma are warranted.

    We have observed 428 patients with hemorrhages of the upper gastrointestinal tract; 7% of patients with stress lesions of the gastroduodenal mucosa being the cause of hemorrhages (4.9% were erosional stress hemorrhages and 2.1% were stress ulcera). Surgery is the most common cause of stress hemorrhages of the stomach and duodenum. They occur during the first 5 days after the surgery, whereas 70.59% (n = 12) occur during the first 72 hours. The localization of erosional hemorrhages of the stomach mucosa is mostly diffuse and that is why they are numerous (78.6% of the third degree) and hemorrhages are mostly heavy (the case with stress hemorrhages). Chronic peptic ulcera, especially duodenal (62.5% duodenal ulcera and 37.5% stomach ulcera) present an expressed risk factor for the occurrence of hemorrhagic erosions under the influence of the stress factor. The most common localization of the stress hemorrhagic ulcus is duodenum (66.7%) which is a potential danger for occurrence of the heaviest arterial hemorrhages. After major surgeries and during postoperative periods patients must be preventively protected by "antiulcus therapy" (especially patients with ulcera).

It is relatively uncommon in the West. it usually presents with either hepatorenal or pulmonary involvement, two forms which generally overlap to a certain degree. We report a case of severe onset hemorrhagic pulmonary leptospirosis in a man who, during the course of the disease, presented multi systemic embolism (spleen, kidney and central nervous system).

    We report a case of life-threatening hematemesis due to portal hypertension caused by an isolated arterioportal fistula (APF). Intrahepatic APFs are extremely rare and are a cause of presinusoidal portal hypertension. Etiologies for APFs are comprised of precipitating trauma, malignancy, and hereditary hemorrhagic telangiectasia, but these were not the case in our patient. Idiopathic APFs are usually due to congenital vascular abnormalities and thus usually present in the pediatric setting. T...

    Full Text Available Dengue fever is a viral infection transmitted by the mosquito, Aedes aegypti. Cardiac rhythm disorders, such as atrioventricular blocks and ventricular ectopic beats, appear during infection and are attributed to viral myocarditis. However, supraventricular arrhythmias have not been reported. We present a case of acute atrial fibrillation, with a rapid ventricular rate, successfully treated with intravenous amiodarone, in a 62-year-old man with dengue hemorrhagic fever, who had no structural heart disease.

    Full Text Available Background Cerebral superficial vein thrombosis was rare and often misdiagnosed or missed for its various etiological factors, and complicated and nonspecific clinical manifestations. This paper reported one case of superficial vein thrombosis in right fronto-parietal lobe with hemorrhagic infarction. The anatomy of superficial vein, pathophysiological points, diagnosis and treatment of superficial vein thrombosis were reviewed to help to reduce missed diagnosis or misdiagnosis. Methods and Results A 18-year-old male patient had suffered from progressive headache for 4 years and weakness of left limbs for 2 d. Head MRI showed circular space-occupying lesion in right fronto-parietal lobe. Magnetic resonance venography (MRV examination showed the front two-thirds of the superior sagittal sinus was not clear. The lesions were removed and decompressive craniectomy was conducted, showing the brain tissue was pale, partly yellow or dark red, and superficial venous engorgement. Histological observation showed pial superficial vein thrombosis and subpial encephalomalacia, and multifocal hemorrhage of cerebral cortex and local parenchymal hemorrhage. A large number of "grid cells" and vascular "cuff" phenomenan were visible in surrounding tissue, and the parenchymal blood vessel proliferation was obvious. Left hand activity of the patient was obviously limited after the operation. Conclusions Clinical diagnosis of superficial vein thrombosis with hemorrhagic infarction is difficult, and brain imaging and serological examination can provide certain help. Much attention should be paid to the multidisciplinary diagnosis and treatment to reduce misdiagnosis or missed diagnosis, and gather clinical experience. DOI: 10.3969/j.issn.1672-6731.2016.01.007

    Full Text Available Objective To analyze the clinical features of multiple spontaneous intracerebral hemorrhages (MICH. Methods Conservative therapy, puncture and drainage, hematoma removal and/or decompressive craniectomy were used in the treatment of 630 intracerebral hemorrhage (ICH patients, who were divided into 2 groups: 30 cases with MICH and another 600 cases with solitary intracerebral hemorrhage (SICH. Three months after onset, modified Rankin Scale (mRS was used to evaluate the prognosis of all cases. Results Compared with patients in SICH group, the occurrence rate of hypertension > 5 years (P = 0.008, diabetes mellitus (P = 0.024, hypercholesterolemia (P = 0.050 and previous ischemic stroke (P = 0.026 were all significantly higher in MICH group. The mean arterial pressure (MAP level (P = 0.002 and the incidence of limb movement disorder (P = 0.000 were significantly higher in patients with MICH than those with SICH. Basal ganglia and thalamus were the predilection sites of hematoma (P = 0.001. Patients with MICH had worse prognosis compared to those with SICH 3 months after onset (P = 0.006. Conclusions Hypertension > 5 years, diabetes mellitus, hypercholesterolemia and ischemic stroke were identified to be the pathophysiological basis of MICH in this study.

  5. Isolated Subarachnoidal Hemorrhage following Carotid Endarterectomy

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available Cerebral hyperperfusion syndrome is a rare but well-described complication following carotid endarterectomy or stenting. Clinical signs are ipsilateral, throbbing, unilateral headache with nausea or vomiting, seizures, and neurological deficits, with or without intracerebral abnormalities on CT scan, such as brain edema or intracerebral hemorrhage. Subarachnoidal hemorrhage is rarely described especially if it occurs isolated. We describe a 74-year-old man with a history of high blood pressure, hypercholesterolemia, atrioventricular block with pacemaker, and ischemic cardiopathy with coronary bypass. He underwent right carotid endarterectomy for a 90% NASCET asymptomatic stenosis. Four days after surgery, he complained of unusual headaches with right, throbbing hemicrania. Nine days after surgery, he presented with left hemiplegia and a partial motor seizure. He had fluctuant altered consciousness, left hemiplegia, and left visual and sensory neglect. Brain CT showed right frontal subarachnoidal hemorrhage without parenchymal bleeding. Cerebral angiography found no cerebral aneurysm, no vascular malformation, but a vasospasm of the left middle cerebral artery. Transcranial Doppler confirmed this vasospasm. Evolution was favorable with no recurrence of seizures but with an improvement of the neurological deficits and vasospasm. Physicians should bear in mind this very rare complication of endarterectomy and immediately perform neuroimaging in case of unusual headache following endarterectomy or angioplasty.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

  7. Intraventricular hemorrhage after dural fistula embolization

    Joana Chaves Gonçalves Rodrigues de Carvalho

    Full Text Available Abstract Background and objectives: Dural arteriovenous fistulas are anomalous shunts between dural arterial and venous channels whose nidus is located between the dural leaflets. For those circumstances when invasive treatment is mandatory, endovascular techniques have grown to become the mainstay of practice, choice attributable to their reported safety and effectiveness. We describe the unique and rare case of a dural arteriovenous fistula treated by transarterial embolization and complicated by an intraventricular hemorrhage. We aim to emphasize some central aspects of the perioperative management of these patients in order to help improving the future approach of similar cases. Case report: A 59-year-old woman with a previously diagnosed Cognard Type IV dural arteriovenous fistula presented for transarterial embolization, performed outside the operating room, under total intravenous anesthesia. The procedure underwent without complications and the intraoperative angiography revealed complete obliteration of the fistula. In the early postoperative period, the patient presented with clinical signs of raised intracranial pressure attributable to a later diagnosed intraventricular hemorrhage, which conditioned placement of a ventricular drain, admission to an intensive care unit, cerebral vasospasm and a prolonged hospital stay. Throughout the perioperative period, there were no changes in the cerebral brain oximetry. The patient was discharged without neurological sequelae. Conclusion: Intraventricular hemorrhage may be a serious complication after the endovascular treatment of dural arteriovenous fistula. A close postoperative surveillance and monitoring allow an early diagnosis and treatment which increases the odds for an improved outcome.

    Full Text Available History of present illness: A 35-year-old female presented to the ED with a Glasgow Coma Scale (GCS of 11. Per her boyfriend, the patient was having headaches for the past 3 weeks. She was initially taken to an outside hospital where her GCS was reported as 13. A non-contrast head computed tomography (CT revealed a large lobar intraparenchymal hemorrhage within the left frontal parietal lobe with midline shift. Upon examination, vitals were notable for blood pressure of 209/88mmHg, and her left pupil was fixed and dilated. The patient had extension of her right arm to noxious stimuli, paralysis of her right leg, and purposeful movement of the left arm and left leg. The patient was started on a nicardipine drip in the ED and subsequently taken to the operating room for a decompressive craniectomy. Significant findings: The patient’s head CT showed a significant area of hyperdensity consistent with an intracranial hemorrhage located within the left frontal parietal lobe (red arrow. Additionally, there is rightward midline shift up to 1.1cm (green arrow and entrapment of the right lateral ventricle (blue arrow. Discussion: Intraparenchymal hemorrhage (IPH is associated with high morbidity and mortality. Although the mortality for subarachnoid hemorrhage (SAH has declined steadily over the past several decades, the mortality for IPH mortality has not significantly.1 One of the most serious considerations when treating a patient with IPH is the management of intracranial pressure (ICP.2 Once an IPH is identified, immediate steps should be taken to bring ICP within acceptable levels including elevating the head of the bed to 30 degrees, sedation, and controlling hypertension with medications.2-3 Even with early and aggressive care, the prognosis for IPH remains poor; the 30-day mortality rate for IPH is estimated to be less than 50%, and a 2010 systematic review estimated only 12-39% of IPH patients achieve independent function.4-5 Predictors of

    To describe the chest radiographic and CT findings of diffuse pulmonary hemorrhage. Two radiologists retrospectively analysed the chest radiographic and CT findings of six patients with diffuse pulmonary hemorrhage. Using open lung biopsy(n=3D2) and transbronchial lung biopsy or bronchoalveolar lavage(n=3D4), diagnosis was based on the presence of hemosiderin-laden macrophage or intra-alveolar hemorrhage. Underlying diseases were Wegener's granulomatosis(n=3D2), antiphospholipid antibody syndrome(n=3D2), Henoch-Schonlein purpura(n=3D1), and idopathic pulmonary hemosiderosis(n=3D1). In all patients, sequential chest radiographs, obtained during a one to six-month period, were available. HRCT scans were obtained in five patinets, and conventional CT scans in one. Follow-up HRCT scans were obtained in two. We also analyzed the patterns of involvement, distribution and sequential changes in the pulmonary abnormalities seen on chest radiographs and CT scans. Chest radiographs showed multifocal patchy consolidation(n=3D6), ground-glass opacity(n=3D3), and multiple granular or nodular opacity(n=3D3). These lesions were intermingled in five patients, while in one there was consolidation only. Sequential chest radiographs demonstrated the improvement of initial pulmonary abnormalities and appearance of new lesions elsewhere within 5-6 days, though within 7-25 (average, 13) days, these had almost normalized. HRCT scans showed patchy consolidation(n=3D5), multiple patchy ground-glass opacity(n=3D5), or ill-defined air space nodules(n=3D4). These lesions were intermingled in five patients, and in one, ground-glass opacity only was noted. In two patients there were interlobular septal thickening and intalobular reticular opacity. The distribution of these abnormalities was almost always bilateral, diffuse with no zonal predominancy, and spared the apex of the lung and subpleural region were less affected. Although chest radiographic and CT findings of diffuse pulmonary

    Terson syndrome refers to oculocerebral syndrome of retinal and vitreous hemorrhage associated with spontaneous subarachnoid hemorrhage or all forms of intracranial bleeding. Recent observations have indicated that patients with spontaneous subarachnoid hemorrhage have an 18% to 20% concurrent incidence of retinal and vitreous hemorrhages with about 4% incidence of vitreous hemorrhage alone. Clinical ophthalmologic findings may have significant diagnostic and prognostic value for clinicians. Here we report a 45-year-old female patient who suffered from blurred vision after subarachnoid hemorrhage. She was diagnosed as Terson syndrome. After vitrectomy, she recovered with normal visual acuity which facilitated the rehabilitative process. We also performed visual evoked potentials to investigate abnormalities of visual dysfunction. Based on this case, we emphasize the importance of early diagnosis of Terson syndrome.

    Operative mortality and morbidity for intracerebral aneurysms has recently reduced with microsurgical technique, so more functional prognosis such as visual disturbance due to fundal hemorrhages has been studied. Here vitreous hemorrhage secondary to ruptured cerebral aneurysms (Terson syndrome) was attentioned. Three patients had more over 2 hours of unconsciousness and one patient experienced repeated episodes of subarachnoid hemorrhage within a week. This suggested rapid increased intracranial pressure resulted in vitreous hemorrhage through the venous congestion, which had been reported by Castrén (1963). All patients became blind because of severe vitreous hemorrhage. First case was followed over 7 years with only conservative therapy, but failed to improve. Another 3 cases regained visual acuity soon after operation. We emphasized vitreous hemorrhage as an important functional prognostic factor after ruptured intracerebral aneurysms and effective results of vitrectomy was showed.

    Intraventricular hemorrhage is a common complication of preterm infants. Mutations in the type IV procollagen gene, COL4A1, are associated with cerebral small vessel disease with hemorrhage in adults and fetuses. We report a rare variant in COL4A1 associated with intraventricular hemorrhage in dizygotic preterm twins. These results expand the spectrum of diseases attributable to mutations in type IV procollagens.

    We have been able to create a reproducible experimental model of nonexpulsive massive suprachoroidal hemorrhage in a rabbit eye. Massive suprachoroidal hemorrhage was demonstrated on echography and confirmed on histopathologic examination in all eyes. The natural course of the disease suggests that there is very little change in the size of the choroidal detachment in the first 7 days. Maximum liquefaction of the suprachoroidal hemorrhage clot was seen to occur between 7 and 14 days. However,...

  15. Modeling intracerebral hemorrhage growth and response to anticoagulation.

    Directory of Open Access Journals (Sweden)

    Charles H Greenberg

    Full Text Available The mechanism for hemorrhage enlargement in the brain, a key determinant of patient outcome following hemorrhagic stroke, is unknown. We performed computer-based stochastic simulation of one proposed mechanism, in which hemorrhages grow in "domino" fashion via secondary shearing of neighboring vessel segments. Hemorrhages were simulated by creating an initial site of primary bleeding and an associated risk of secondary rupture at adjacent sites that decayed over time. Under particular combinations of parameters for likelihood of secondary rupture and time-dependent decay, a subset of lesions expanded, creating a bimodal distribution of microbleeds and macrobleeds. Systematic variation of the model to simulate anticoagulation yielded increases in both macrobleed occurrence (26.9%, 53.2%, and 70.0% of all hemorrhagic events under conditions simulating no, low-level, and high-level anticoagulation and final hemorrhage size (median volumes 111, 276, and 412 under the same three conditions, consistent with data from patients with anticoagulant-related brain hemorrhages. Reversal from simulated high-level anticoagulation to normal coagulation was able to reduce final hemorrhage size only if applied relatively early in the course of hemorrhage expansion. These findings suggest that a model based on a secondary shearing mechanism can account for some of the clinically observed properties of intracerebral hemorrhage, including the bimodal distribution of volumes and the enhanced hemorrhage growth seen with anticoagulation. Future iterations of this model may be useful for elucidating the effects of hemorrhage growth of factors related to secondary shearing (such as small vessel pathology or time-dependent decay (such as hemostatic agents.

    Subacute subdural hematoma (SASDH) is an entity which is yet to capture the popular imagination among the neurosurgeons. Its management is often equated clinically to that of the chronic subdural hematoma (CSDH). However, their neurological deterioration is usually rapid, which seems to align them with acute subdural hematoma (ASDH). We proceed for their epidemiological evaluation. The advantages of a novel "double barrel technique (DbT)" over the conventional burrhole drainage are also presented. This retrospective study was conducted on all the patients having clinical and radiological evidence of SASDH, admitted to a tertiary care referral institute, during the period August 2013 to December 2015. Postoperatively, patients were followed-up for 3-24 months. 46.87% of the patients belonged to the 35-54 year age group with a male predominance (3.6:1); 68.7% had a history of alcohol abuse, whereas aspirin users were 25%. 87.5% cases were unilateral, 18.75% were hemispheric, and 46.87% were present on the left side. Altered consciousness (100%) followed by headache (37.5%) were the most common presenting clinical features. SASDH is an uncommon neurosurgical entity (0.89% of traumatic brain injury cases in our study) and mimics both CSDH as well as ASDH. The true incidence of SASDH may have been underestimated due to its clinical imitation with CSDH. This study in a South Asian nation also provides the epidemiological data of this rare neurosurgical entity. Outcome of surgery is good; our retrospective study confirms that "DbT" is an adequate and safe treatment. However, a better designed, randomized control trial will be needed to reinforce our findings.

We report a unique spontaneous hemorrhage during pregnancy in a case with horseshoe kidney with separated adrenal, presented for the first time in the world. Computed tomography scan showed a horseshoe kidney fused with left normal kidney. Interestingly the adrenal gland was remained in right flank and separated from the horseshoe kidney, which prepares a probable physical stress for the hemorrhage. Diagnosis and surgery were done successfully and the case was fully recovered after several days.

    Herpes simplex encephalitis (HSE) can be complicated by adverse events in the acute phase. We herein present the case of a 71-year-old woman with HSE complicated by cerebral hemorrhage. She presented with acute deterioration of consciousness and fever and was diagnosed with HSE based on the detection of herpes simplex virus-1 in the cerebrospinal fluid by a polymerase chain reaction. The cerebral hemorrhage developed during acyclovir therapy; however, its diagnosis was delayed for 2 days. After the conservative treatment of the cerebral hemorrhage, the patient made a near-complete recovery. Cerebral hemorrhage should be considered as an acute-phase complication of HSE.

    Increasing rates of opioid abuse, particularly fentanyl, may lead to more presentations of unusual effects of opioid toxicity. Diffuse alveolar hemorrhage is a rare complication of fentanyl overdose. A 45-year-old male presented in hypoxic respiratory failure secondary to diffuse alveolar hemorrhage requiring intubation. Comprehensive drug screening detected fentanyl without exposure to cocaine. Further history upon the patient's recovery revealed exposure to snorted fentanyl powder immediately prior to presentation. Diffuse alveolar hemorrhage is a potential, though rare, presentation of opioid intoxication. Recognition of less common complications of opioid abuse such as diffuse alveolar hemorrhage is important in proper management of overdoses.

    Full Text Available Dabigatran etexilate is a relatively new anticoagulant from the class of direct thrombin inhibitors which is administered orally and does not require routine blood work monitoring. Dabigatran may be attractive to both clinicians and patients because of both its convenience and efficacy; however, clinical complications are still being elucidated. Here, we present a previously unreported case of spinal subarachnoid and subdural hematoma presenting as a Brown-Séquard-like myelopathy in a patient after minor trauma in the setting of Dabigatran anticoagulation.

    Refractory chronic subdural hematoma (CSDH) is rare but remains a difficulty for neurosurgeons, and no consensus on treatment procedures has been established. To discuss effective surgical procedures for refractory CSDH, we analyzed our surgical procedures and outcomes for refractory CSDH. We defined patients with refractory CSDH as those who presented with two or more recurrences. Fourteen patients with refractory CSDH were analyzed. Eight patients underwent burr-hole irrigation and closed-system drainage alone, four patients received embolization of the middle meningeal artery (MMA), and two patients with organized CSDH underwent large craniotomy with outer membranectomy as the third surgery. Two of the eight patients (25%) treated with burr-hole irrigation and drainage alone showed a third recurrence. No further recurrences were identified in patients treated with embolization of the MMA or craniotomy. However, statistical analysis showed no significant difference in cure rate between patients treated with burr-hole irrigation and drainage alone and patients treated with burr-hole irrigation and drainage with embolization of the MMA (P = .42). Similarly, no significant differences in cure rate were seen between patients treated with burr-hole irrigation and drainage alone and patients treated with craniotomy (P = .62). When selecting a surgical procedure, assessing whether the CSDH is organized is crucial. Embolization of the MMA may be considered as one of the optional treatments for refractory CSDH without organized hematoma. On the other hand, for refractory cases of organized CSDH, hematoma evacuation and outer membranectomy with large craniotomy or mini-craniotomy assisted by an endoscope may be suitable, as previous reports have recommended.

    There are limited data with regards to the associated risk of post-operative seizures in patients with surgically treated chronic subdural hematomas (CSDHs). The use of anti-epileptic drugs (AEDs) is associated with significant side effects. A retrospective chart review was performed on patients operated via burr hole for CSDH in our institution from 2004 to 2013. Post-operative seizures at 1-year follow-up were identified. Demographic data, medical history, and imaging characteristics were recorded. A total of 220 patients were included in the study. Post-operative seizures occurred in 2.3%. The mean time of onset of seizures was 8.4 days. No difference in age and gender between seizing and non-seizing groups was identified p > 0.05. Mean midline shift was 4.6 mm in seizing group vs. 4.2 mm in non-seizing group, p > 0.05. Mean thickness was 14.6 mm in patients without post-operative seizures and 18.4 mm in patients with post-operative seizures, p > 0.05. There was no significant difference in post-operative seizure incidence related to the side or location of the CSDHs. The incidence of post-operative seizures in patients with CSDH evacuated via burr holes was low. Prophylactic AEDs should not be routinely administered if no other risk factor for seizure exists. Demographic and clinical factors did not appear to influence post-operative seizures.

    Recurrence rates after chronic subdural hematoma (CSDH) evacuation with any of actual techniques [twist-drill craniostomy (TDC), burr-hole craniostomy, craniotomy] range from 5% to 30%. Use of drain has improved recurrence rates when used with burr-hole craniostomy. Now, we analyze predictors of recurrence of TDC with drain. Three hundred twelve consecutive patients with CSDH have been studied in a retrospective study. Operative technique in all patients consisted in TDC with drain. Data recorded included any associated comorbidity. Radiologic measures of the CSDH before and after the procedure were studied. Clinical evaluation included Modified Rankin Scale, Glasgow Coma Scale (GCS), and neurological deficits. Two groups were compared: recurrence group and nonrecurrence group. Follow-up was for at least 1 year. Twelve percent experienced recurrence. Preoperative CSDH width, preoperative midline shift, postoperative midline width, postoperative CSDH width, and residual CSDH 1 month later were significantly associated with CSDH recurrence. The logistic regression model for the multivariate analysis revealed that postoperative midline shift and postoperative neurological deficit were significantly associated with CSDH recurrence. The duration of treatment with dexamethasone was found not to be related with recurrence. Mortality before hospital discharge was 1%. Hospital stay was 2.5 days. TDC with drain has similar results in recurrence rates, morbidity, mortality, and outcome as other techniques as burr-hole craniostomy with drain. Preoperative and postoperative hematoma width and midline shift are independent predictors of recurrence. Brain re-expansion and time of drain maintenance are important factors related with recurrence of CSDH. Future CSDH reservoirs must avoid negative pressure and sudden pressure changes inside the whole closed drain system.

    Several recent global traumatic brain injury (TBI) initiatives rely on practice variation in diagnostic and treatment methods to answer effectiveness questions. One of these scientific dilemmas, the surgical management of the traumatic acute subdural hematoma (ASDH) might be variable among countries, among centers within countries, and even among neurosurgeons within a center, and hence be amenable for a comparative effectiveness study. The aim of our questionnaire, therefore, was to explore variations in treatment for ASDH among neurosurgeons in similar centers in a densely populated geographical area. An online questionnaire, involving treatment decisions on six case vignettes of ASDH, was sent to 93 neurosurgeons in The Netherlands and Belgium. Clinical and radiological variables differed per case. Sixty neurosurgeons filled out the questionnaire (response rate 65%). For case vignettes with severe TBI and an ASDH, there was a modest variation in the decision to evacuate the hematoma and a large variation in the decision to combine the evacuation with a decompressive craniectomy. The main reasons for operating were "neurological condition" and "mass effect." For ASDH and mild/moderate TBI, there was large variation in the decision of whether to operate or not, whereas "hematoma size" was the predominant motivation for surgery. Significant inter-center variation for the decision to evacuate the hematoma was observed (p = 0.01). Most pronounced was that 1 out of 7 (14%) neurosurgeons in one region chose a surgical strategy compared with 9 out of 10 (90%) in another region for the same scenario. In conclusion, variation exists in the neurosurgical management of TBI within an otherwise homogeneous setting. This variation supports the methodology of the international Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) initiative, and shaped the Dutch Neurotraumatology Quality Registry (Net-QuRe) initiative.

    OBJECTIVE Subdural hematoma (SDH) is the most common serious adverse event in patients with shunts. Adjustable shunts are used with increasing frequency and make it possible to noninvasively treat postoperative SDH. The objective of this study was to describe the prevalence and treatment preferences of SDHs, based on fixed or adjustable shunt valves, in a national cohort of patients with shunted idiopathic normal pressure hydrocephalus (iNPH), as well as to evaluate the effect of SDH and treatment on long-term survival. METHODS Patients with iNPH who received a CSF shunt in Sweden from 2004 to 2015 were included in a prospective quality registry (n = 1846) and followed regarding SDH, its treatment, and mortality. The treatment of SDH was categorized into surgery, opening pressure adjustments, or no treatment. RESULTS During the study period, the proportion of adjustable shunts increased from 75% to 95%. Ten percent (n = 184) of the patients developed an SDH. In 103 patients, treatment was solely opening pressure adjustment. Surgical treatment was used in 66 cases (36%), and 15 (8%) received no treatment. In patients with fixed shunt valves, 90% (n = 17) of SDHs were treated surgically compared with 30% (n = 49) in patients with adjustable shunts (p SDH and non-SDH groups or between different treatments. CONCLUSIONS SDH remains a common complication after shunt surgery, but adjustable shunts reduced the need for surgical interventions. SDH and treatment did not significantly affect survival in this patient group, thus the noninvasive treatment offered by adjustable shunts considerably reduces the level of severity for this common adverse event.

    A vast amount of literature has been published investigating the factors associated to the recurrence of a chronic subdural hematoma (SDH). However, little exists in the literature about the best medical management of the residual SDH in order to prevent the recurrence. Moreover only few studies quantitatively assess clinical and radiological outcomes of residual post-operative SDH. In this study, to our knowledge, we report the first series of chronic SDH with a quantitative outcomes analysis of the effects of fluid therapy on residual post-operative SDH. Moreover we discuss the pertinent literature. We reviewed clinical and outcome data of 39 patients (44 SDH; 12 F, 27 M) submitted to a burr-hole evacuation of a SDH. The mean age was 76.97±7.77years. All patients had a minimum 3-month follow-up (FU). Post-operatively, an intravenous saline solution was started in all cases (2000ml in 24h) and administered for 3days. Then an oral hydration with 2l per day of water was started and continued as outpatients. Glasgow Coma Scale (GCS), Karnofsky Performance Status (KPS), SDH volume and midline shift were evaluated pre-operatively, post-operatively and at FU. We found a statistically significant improvement of post-operative and at FU GCS and KPS compared to the pre-operative. SDH volume and midline shift were also statistically significant reduced in the post-operative and at FU. No complication occurred. Only 1 patient required a reoperation at 3months FU for neurological worsening. Oral fluid therapy is a safe and effective treatment for residual SDH. Copyright © 2017 Elsevier Ltd.

    OBJECTIVE Aging of the population may lead to epidemiological changes with respect to chronic subdural hematoma (CSDH). The objectives of this study were to elucidate the current epidemiology and changing trends of CSDH in Japan. The authors analyzed patient information based on reports using a Japanese administrative database associated with the diagnosis procedure combination (DPC) system. METHODS This study included patients with newly diagnosed CSDH who were treated in hospitals participating in the DPC system. The authors collected data from the administrative database on the following clinical and demographic characteristics: patient age, sex, and level of consciousness on admission; treatment procedure; and outcome at discharge. RESULTS A total of 63,358 patients with newly diagnosed CSDH and treated in 1750 DPC participation hospitals were included in this study. Analysis according to patient age showed that the most common age range for these patients was the 9th decade of life (in their 80s). More than half of patients 70 years old or older presented with some kind of disturbance of consciousness. Functional outcomes at discharge were good in 71.6% (modified Rankin Scale [mRS] score 0-2) of cases and poor in 28.4% (mRS score 3-6). The percentage of poor outcomes tended to be higher in elderly patients. Approximately 40% of patients 90 years old or older could not be discharged to home. The overall recurrence rate for CSDH was 13.1%. CONCLUSIONS This study shows a chronological change in the age distribution of CSDH among Japanese patients, which may be affecting the prognosis of this condition. In the aging population of contemporary Japan, patients in their 80s were affected more often than patients in other age categories, and approximately 30% of patients with CSDH required some help at discharge. CSDH thus may no longer have as good a prognosis as had been thought.

    Hemorrhagic cystitis (HC) presenting with gross hematuria, bladder pain and urinary frequency develops in 13-38% of patients following bone marrow transplantation (BMT). The objective of the study was to study the characteristics of patients suffering hemorrhagic cystitis after hematopoietic stem cell transplantation in our center. We conducted a retrospective chart review of all patients who underwent BMT at our institution between January 1996 and August 2012. We recorded the age, sex, diagnosis, conditioning regimen, interval between BMT and development of symptoms of cystitis and treatment instituted. Five hundred patients underwent BMT in the period of time studied. 52 of them developed hemorrhagic cystitis. The mean age of the affected patients was 39 years; there were 34 males and 18 females. The diagnoses include AML (n=11), ALL (n=8), CML (n=6), MDS (n=11), CLL (n=5), NHL (n=1), HD (n=5), MM (n=2), Medular aplasia((n=3). HC appeared 59.48 days after BMT. There were no differences between sexes. Mortality among the 52 patients was 51.14% but HC was not the cause of death in any patient. Polyomaviruses were detected in the urine of 78.94 % of survivors. Polyomavirus infection with BK and JC types is usually acquired in infancy and the virus remains latent in renal tissue. Immunosuppression facilitates reactivation of the renal infection and replication of the virus responsible for the clinical manifestations of HC. The differential diagnoses include other urinary infections, lithiasis, thrombocytopenia and adverse effects of pharmacological agents. The urologist plays a limited role in the management of this disease.

    Determine the prevalence of intraventricular hemorrhage in infants with moderate to severe congenital heart disease, investigate the impact of gestational age, cardiac diagnosis, and cardiac intervention on intraventricular hemorrhage, and compare intraventricular hemorrhage rates in preterm infants with and without congenital heart disease. A single-center retrospective review. A tertiary care children's hospital. All infants admitted to St. Louis Children's Hospital from 2007 to 2012 with moderate to severe congenital heart disease requiring cardiac intervention in the first 90 days of life and all preterm infants without congenital heart disease or congenital anomalies/known genetic diagnoses admitted during the same time period. None. Cranial ultrasound data were reviewed for presence/severity of intraventricular hemorrhage. Head CT and brain MRI data were also reviewed in the congenital heart disease infants. Univariate analyses were undertaken to determine associations with intraventricular hemorrhage, and a final multivariate logistic regression model was performed. There were 339 infants with congenital heart disease who met inclusion criteria and 25.4% were born preterm. Intraventricular hemorrhage was identified on cranial ultrasound in 13.3% of infants, with the majority of intraventricular hemorrhage being low-grade (grade I/II). The incidence increased as gestational age decreased such that intraventricular hemorrhage was present in 8.7% of term infants, 19.2% of late preterm infants, 26.3% of moderately preterm infants, and 53.3% of very preterm infants. There was no difference in intraventricular hemorrhage rates between cardiac diagnoses. Additionally, the rate of intraventricular hemorrhage did not increase after cardiac intervention, with only three infants demonstrating new/worsening high-grade (grade III/IV) intraventricular hemorrhage after surgery. In a multivariate model, only gestational age at birth and African-American race were predictors

    Full Text Available We describe a 64-year-old man with extensive diffuse acute lung hemorrhage, presumably as a result of anticoagulation therapy. We evaluated reports in the literature concerning acute exacerbation (acute lung injury of unknown cause in UIP and other forms of fibrotic interstitial pneumonias. We also evaluated autopsy tissue in this case in order to determine the cause of death in this 64-year-old man, who was initially thought to have an asbestos-related disease. Based on the autopsy findings, this man died as a result of anticoagulation therapy; specifically, the use of Xarelto® (rivaroxaban.

    Wegener granulomatosis (WG) is a necrotizing granulomatous vasculitis that predominantly affects airways and kidneys. But central nervous system involvement (7-11%) is an uncommon. Massive ICH may occur in the course of WG, and this serious condition is related with high risk of mortality. Therefore, the new treatment strategies may be considered in addition to classical practices in serious organ involvement and recurrent attack. Here, we present an adult patient with WG whose disease was complicated by a massive intracerebral hemorrhage (ICH), which subsequently led to death.

    Computed tomography was used to examine 100 patients with extracranial hemorrhage. Of these patients, 29 had serial scans that allowed for the study of evolutionary changes. Operation, anticoagulation, and trauma were the prime etiological factors. The most frequent sites included the retroperitoneum (27%), body wall or extremities (24%), peritoneal cavity (19%), and subcapsular (16%) and intraparenchymal (7%) locations. The computed tomographic features were carefully studied and documented. Age-related features included contrast-material extravasation, inhomogeneity, hematocrit effect, attenuation changes, lucent halo, pseudocapsule development, decreased size with time, peripheral calcification, and fascial plane thickening. This report discussed all these findings and their usefulness in diagnosis and patient care.

    Full Text Available The purpose of this study was to investigate using light microscopy the fibro-cellular components of arachnoid granulations affected by mild and severe subarachnoid hemorrage. The erythrocytes were in the channels delimitated by collagenous and elastic bundles and arachnoid cells, showing their tortuous and intercommunicating row from the pedicle to the fibrous capsule. The core portion of the pedicle and the center represented a principal route to the bulk outflow of cerebrospinal fluid and erythrocytes. In the severe hemorrhage, the fibrocellular components are desorganized, increasing the extracellular channels. We could see arachnoid granulations without erythrocytes, which cells showed big round nucleous suggesting their transformation into phagocytic cells.

    We report a case of life-threatening hematemesis due to portal hypertension caused by an isolated arterioportal fistula (APF). Intrahepatic APFs are extremely rare and are a cause of presinusoidal portal hypertension. Etiologies for APFs are comprised of precipitating trauma, malignancy, and hereditary hemorrhagic telangiectasia, but these were not the case in our patient. Idiopathic APFs are usually due to congenital vascular abnormalities and thus usually present in the pediatric setting. This is one of the first cases of adult-onset isolated APF who presented with portal hypertension and was successfully managed through endoscopic hemostasis and subsequent interventional radiological embolization.

    Aneurysmal subarachnoid hemorrhage (aSAH) and spontaneous intracranial hemorrhage (ICH) are frequently associated with epileptic complications. The use of anti-epileptic drugs (AEDs) for seizure prophylaxis, however, is controversial. In patients with aSAH, nonconvulsive status epilepticus has been associated with poor outcome. Effect of other forms of less severe epileptiform activity on clinical outcome remains unclear. Evidence on efficacy of AEDs in reducing seizure incidence is also mixed. However, increasing number of studies suggest that AEDs may have significant adverse effects on outcome, especially with phenytoin. Similarly, in patients with ICH, the impact of seizures that do not progress to status epilepticus on clinical outcome is controversial, and whether prophylactic AED use has independent effects on outcome remains ambiguous. Currently, there are no large scale randomized control trials investigating the efficacy and safety of AED prophylaxis in patients with hemorrhagic stroke. There are also no trials comparing the efficacy and safety of the different AEDs. Survey based studies have found a wide range of prescribing patterns across treatment centers and clinicians for seizure prophylaxis in patients with hemorrhagic stroke. The lack of clear guidelines and recommendations also highlights the paucity of good quality evidence in this area. In conclusion, a well-designed randomized, double blinded, and appropriately powered trial is needed to evaluate the incidence as well as clinical outcomes in patients with aSAH and ICH who received AED prophylaxis versus controls. The results will be extremely valuable in providing evidence to establish management guidelines for patients with hemorrhagic stroke.

    Several studies have suggested the possible influence of postoperative bed header position on the risk of symptomatic recurrences and medical complications in patients who have been intervened due chronic subdural haematomas. Nevertheless, this hypothesis has not been assessed by a meta-analysis. All randomised controlled trials analysing symptomatic recurrence rates in patients who underwent burr-hole drainage of chronic subdural haematomas, describing postoperative bed header positioning, were included. The primary outcome was risk of recurrence and the secondary outcome were the risks of reoperation and medical complications. Results were presented as pooled relative risks, with 95% confidence intervals. A total of 4 controlled studies were included. Pooled relative risks were: symptomatic recurrences 0.51 ([95% CI: 0.22-1.16]; P=.11), reoperations, 1.07 ([95% CI: 0.42-2.69]; P=.89) and medical complications, 1.15 ([95% CI: 0.7-1.91]; P=.58). No statistically significant heterogeneity was found in any of the analyses. There were no differences regarding frequency of symptomatic recurrences, reoperations or medical complications in patients who were maintained in a flat position compared with those whose bed header was elevated during the postoperative course. Despite there being consistency between the results, there is a potential risk of bias; thus proscribing definitive recommendations until studies with higher methodological quality are available.
