    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.

    Full Text Available Background: Some complications related to vertebral artery occlusion by endovascular technique have been reported. However, cerebellar hemorrhage after vertebral artery occlusion in subacute phase is rare. In this report, we describe a patient who showed cerebellar hemorrhage during hypertensive therapy for vasospasm after embolization of a vertebral dissecting aneurysm. Case Description: A 56-year-old female with a ruptured vertebral dissecting aneurysm proximal to the posterior inferior cerebellar artery developed cerebellar hemorrhage 15 days after embolization of the vertebral artery, including the dissected site. In this patient, the preserved posterior inferior cerebellar artery fed by retrograde blood flow might have been hemodynamically stressed during hypertensive and antiplatelet therapies for subarachnoid hemorrhage, resulting in cerebellar hemorrhage. Conclusion: Although cerebellar hemorrhage is not prone to occur in the nonacute stage of embolization of the vertebral artery, it should be taken into consideration that cerebellar hemorrhage may occur during hypertensive treatment.

    Fourteen cases of cerebellar hemorrhage were analysed from the point of CT-scan, and the following results were obtained. 1. The number of cases of cerebellar hemorrhage forms 4.4% of that of total intracranial hemorrhage. 2. Most of the cerebellar hematomas extend upward. Downward extension is rare. 3. In acute dead cases hematomas are 5 cm or more in diameter and lie over bilateral hemispheres with the extension to third or fourth ventricles in CT-scans. 4. Slowly progressive cases are detriorated by the secondary hydrocephalus. 5. In mild cases hematomas are 3cm or less in diameter on CT-scans and the hematoma evacuation is not indicated for these cases. 6. The shunt operation alone is sufficient for the life saving of the slowly progressive cases, but the hematoma evacuation is indicated in these cases if the functional prognosis is taken into consideration. 7. Immediate hematoma evacuation together with the ventricular drainage is considered to be effective for the life saving of the acute fulminant cases.

    Abstract Rationale: Remote cerebellar hemorrhage (RCH) is a rare complication of supratentorial and spinal surgeries, seldom requiring intervention but occasionally causing significant morbidity or even mortality. Although a number of theories have been proposed, the exact pathophysiology of RCH remains incompletely understood. Patient concerns: We present a 62-year-old patient with RCH encountered following surgical clipping of an unruptured middle cerebral artery bifurcation aneurysm in a patient with previous cerebellar infarction. Lessons: It is extremely rare, but sometimes, RCH can be life-threatening. It is necessary to check the patient's general condition, underlying diseases and medical history. And controlled drainage of the CSF seems to be most important. Arachnoidplasty may be a consideration and the position of the drain string might have to be carefully determined. PMID:28121936

    We report here on a neonate with congenital cerebellar mixed germ cell tumor, and this initially presented as cerebellar hemorrhage. Postnatal cranial ultrasonography revealed an echogenic cerebellar mass that exhibited the signal characteristics of hemorrhage rather than tumor on MR images. The short-term follow-up images also suggested a resolving cerebellar hemorrhage. One month later, the neonate developed vomiting. A second set of MR images demonstrated an enlarged mass that exhibited changed signal intensity at the same site, which suggested a neoplasm. Histological examination after the surgical resection revealed a mixed germ cell tumor.

    Adverse events related to oral anticoagulants represent a major public health problem. Hemorrhagic episodes are the most frequent complications and can be life-threatening. A 10 month prospective survey on all cases treated with anti-vitamin K (AVK), and admitted to emergency room of CHU Grenoble, was conducted to identify the hemorrhagic adverse drug events (HADE). The evaluation support was a directive questionnaire and consisted of 3 parts: patient characteristics, patient's medicated treatment and the hemorrhagic event. 216 patients treated with AVK were identified and 68 of them presented a hemorrhagic adverse drug event. 60 patients older than 65 years out of 158, presented HADE (38%); versus 8 patients or = 5, 79% developed HADE versus 16% in the group who had their INR AVK were significant. Concerning missed dose, 48 patients declared taking the missed dose with the next dose or when they remembered: 35% of them developed HADE (p = 0.49).

    Infratentorial cerebral hemorrhage due to a direct carotid–cavernous fistula (CCF) is very rare. To our knowledge, only four such cases have been reported. Cerebellar hemorrhage due to a direct CCF has not been reported. We describe a 63-year-old female who presented with reduced consciousness 3 days after undergoing a maxillectomy for maxillary cancer. Computed tomography showed a cerebellar hemorrhage. Magnetic resonance angiography showed a left-sided direct CCF draining into the left petrosal and cerebellar veins through the left superior petrosal sinus (SPS). Her previous surgery had sacrificed the pterygoid plexus and facial vein. Increased blood flow and reduced drainage could have led to increased venous pressure in infratentorial veins, including the petrosal and cerebellar veins. The cavernous sinus has several drainage routes, but the SPS is one of the most important routes for infratentorial venous drainage. Stenosis or absence of the posterior segment of the SPS can also result in increased pressure in the cerebellar and pontine veins. We emphasize that a direct CCF with cortical venous reflux should be precisely evaluated to determine the hemodynamic status and venous drainage from the cavernous sinus. PMID:28061497

  9. A rare case of infantile cerebellar pilocytic astrocytoma and thrombocytopenia presenting with intratumoral hemorrhage

    2016-01-01

    Full Text Available Incidence of gliomas presenting with hemorrhage is around 3.7–7.2%. Low-grade gliomas account for <1% tumor with hemorrhage. Infants presenting with cerebellar pilocytic astrocytomas (PAs and hemorrhage with thrombocytopenia have not been reported. We report an interesting case of a 9-month-old infant who presented to the emergency department in a drowsy state with recurrent vomiting. Laboratory investigations showed anemia, thrombocytopenia, and coagulopathy. Radiological evaluation showed a large PA with bleed. The patient was treated with retromastoid suboccipital craniotomy and tumor excision and improved postoperatively. Cerebellar PA with bleed and coagulopathy in infants has not been reported in literature till date. Their presentation seems to be acute in nature, and high index of suspicion is required for the diagnosis of these posterior fossa tumors, which can deteriorate rapidly in infants.

    Full Text Available Occipital condyle fractures (OCFs have been treated as rare traumatic injuries, but the number of reported OCFs has gradually increased because of the popularization of computed tomography (CT and magnetic resonance imaging (MRI. The patient in this report presented with OCFs and C1 dislocation, along with traumatic cerebellar hemorrhage, which led to craniovertebral junction instability. This case was also an extremely rare clinical condition in which the patient presented with traumatic lower cranial nerve palsy secondary to OCFs. When the patient was transferred to our hospital, the occipital bone remained defective extensively due to surgical treatment of cerebellar hemorrhage. For this reason, concurrent cranioplasty was performed with resin in order to fix the occipital bone plate strongly. The resin-made occipital bone was used to secure a titanium plate and screws enabled us to perform posterior fusion of the craniovertebral junction. Although the patient wore a halo vest for 3 months after surgery, lower cranial nerve symptoms, including not only neck pain but also paralysis of the throat and larynx, improved postoperatively. No complications were detected during outpatient follow-up, which continued for 5 years postoperatively.

    Objective: To assess the risk factors leading to medical complications of hemorrhagic stroke. Methods: We conducted an observational study in neurology, emergency and general medicine wards at a tertiary care teaching hospital in Kadapa. We recruited hemorrhagic stroke patients, and excluded the patients have evidence of trauma or brain tumor as the cause of hemorrhage. We observed the subjects throughout their hospital stay to assess the risk factors and complications. Results: During period of 12 months, 288 subjects included in the study, 89% of them identified at least 1 prespecified risk factor for their admission in hospital and 75% of them experienced at least 1 prespecified complication during their stay in hospital. Around 47% of subjects deceased, among which 64% were females. Conclusions: Our study has assessed that hypertension followed by diabetes mellitus are the major risk factors for medical complications of hemorrhagic stroke. Female mortality rate was more when compared to males.

    Full Text Available Arachnoid cysts are developmental anomalies which are usually asymptomatic. Intracystic hemorrhage after trauma is a well known complication; however, spontaneous intracystic hemorrhage is rare. This report presents two rare cases of arachnoid cyst complicated by spontaneous intracystic hemorrhage. The first patient was admitted following transient loss of consciousness and speech disturbance, and a subacute subdural hematoma at the left temporal region was diagnosed. The second patient presented with severe headache of four days duration and a subdural hematoma at the left temporoparietal region was diagnosed. In both the patients, both on radiological examination and during surgical intervention, hematomas were found to be intracystic.

    In this study,we determined the expression levels of matrix metalloproteinase-2 and -9 and matrix metalloproteinase tissue inhibitor-1 and -2 in brain tissues and blood plasma of patients undergoing surgery for cerebellar arteriovenous malformations or primary epilepsy (control group).Immunohistochemistry and enzyme-linked immunosorbent assay revealed that the expression of matrix metalloproteinase-9 and matrix metalloproteinase tissue inhibitor-1 was significantly higher in patients with cerebellar arteriovenous malformations than in patients with primary epilepsy.The ratio of matrix metalloproteinase-9 to matrix metalloproteinase tissue inhibitor-1 was significantly higher in patients with hemorrhagic cerebellar arteriovenous malformations compared with those with non-hemorrhagic malformations.Matrix metalloproteinase-2 and matrix metalloproteinase tissue inhibitor-2 levels were not significantly changed.These findings indicate that an imbalance of matrix metalloproteinase-9 and matrix metalloproteinase tissue inhibitor-1,resulting in a relative overabundance of matrix metalloproteinase-9,might be the underlying mechanism of hemorrhage of cerebellar arteriovenous malformations.

    2013-01-01

    Full Text Available Crossed cerebellar diaschisis (CCD is defined as a reduction in blood flow in the cerebellar hemisphere contralateral to the supratentorial focal lesion. The phenomenon termed parakinesia brachialis oscitans (PBO in which stroke patients experience involuntary stretching of the hemiplegic arm during yawning is rarely reported. The concurrence of CCD and PBO has never been described. A 52-year-old man had putaminal hemorrhage and demonstrated no significant recovery in his left hemiplegia after intensive rehabilitation, but his gait improved gradually. Two months after the stroke, the single photon emission computed tomography (SPECT showed CCD. Four months after the stroke, the patient noticed PBO. The follow-up SPECT showed persistent CCD and the patient’s arm was still plegic. The frequency and intensity of PBO have increased with time since the stroke. We speculate that the two phenomena CCD and PBO might share similar neuroanatomical pathways and be valuable for predicting clinical recovery after stroke.

    Dengue fever is a debilitating mosquito-borne disease caused by dengue virus. We reported a case of femoral compression neuropathy due to iliopsoas hematoma complicating dengue hemorrhagic fever. Iliopsoas muscle hematoma can cause femoral neuropathy with resultant pain and paralysis. Such manifestations are not well documented in the literature. The pathogenesis of hematoma and compressive neuropathy with its appropriate management is discussed.

    The treatment of spontaneous cerebellar hemorrhage is still discussed controversially. We analyzed a series of 57 patients who underwent surgical evacuation of a cerebellar hematoma at our department. Preoperative clinical and radiological parameters were assessed and correlated with the clinical outcome in order to identify factors with impact on outcome. The overall clinical outcome according to the Glasgow Outcome Scale at the last follow-up was good (GOS 4-5) in 27 patients (47%) and poor (GOS 2-3) in 16 patients (28%). Fourteen patients (25%) died. The initial neurological condition and the level of consciousness proved to be significant factors determining clinical outcome (p = 0.0032 and p = 0.0001, respectively). Among radiological parameters, brain stem compression and a tight posterior fossa solely showed to be predictive for clinical outcome (p = 0.0113 and p = 0.0167, respectively). Overall, our results emphasize the predictive impact of the initial neurological condition on clinical outcome confirming the grave outcome of patients in initially poor state as reported in previous studies. The hematoma size solely, in contrast to previous observations, showed not to be predictive for clinical outcome. Especially for the still disputed treatment of patients in good initial neurological condition, a suggestion can be derived from the present study. Based on the excellent outcome of patients with good initial clinical condition undergoing surgery due to secondary deterioration, we do not recommend preventive evacuation of a cerebellar hematoma in these patients.

    The high rates of morbidity and mortality after subarachnoid hemorrhage due to spontaneous rupture of an intracranial aneurysm are mainly the result of neurologic complications. Sixty years after cerebral vasospasm was first described, this problem remains unsolved in spite of its highly adverse effect on prognosis after aneurysmatic rupture. Treatment is somewhat empirical, given that uncertainties remain in our understanding of the pathophysiology of this vascular complication, which involves structural and biochemical changes in the endothelium and smooth muscle of vessels. Vasospasm that is refractory to treatment leads to cerebral infarction. Prophylaxis, early diagnosis, and adequate treatment of neurologic complications are key elements in the management of vasospasm if neurologic damage, lengthy hospital stays, and increased use of health care resources are to be avoided. New approaches to early treatment of cerebral lesions and cortical ischemia in cases of subarachnoid hemorrhage due to aneurysm rupture should lead to more effective, specific management.

    Hemorrhagic complications are the most frequent complications of antivitamin K (AVK) treatments and can be life-threatening. We report 75 patients from a University Hospital. They were 40 males and 35 females (median age 74 years, 20-94), and were classified into 3 grades according to clinical picture: grade 1 (no surgery or transfusion, grade 2: surgery or blood transfusion needed, grade 3: death). 43 patients had grade 1 complications, 27 grade 2, and 5 grade 3 complications. The most frequent complications were muscular hematomas (36 patients), sub-cutaneous hematomas (14 patients), digestive bleeding (13 patients), hematuria (12 subjects). Eight patients had intracerebral bleeding, of whom 3 died. The treatment time was very variable (1 to 988 weeks). Only half patients had a prothrombin rate (PR) below 20% but two thirds had an INR above 5. This study showed that PR was a poor predictor of hemorrhagic complications. INR was a better parameter. For 15 patients, we considered that the indication was unadapted or questionable, among whom 2 died. This work suggests that the promotion of AVK prescription rules should go on.

    Recent diffusion tensor imaging (DTI) studies have demonstrated that leakage of hemosiderin into cerebrospinal fluid (CSF), which is caused by high-grade intraventricular hemorrhage (IVH), can affect cerebellar development in preterm born infants. However, a direct effect of low-grade IVH on cerebellar development is unknown. Thus, we evaluated the cerebellar and cerebral white matter (WM) of preterm infants with low-grade IVH. Using DTI tractography performed at term-equivalent age, we analyzed 42 infants who were born less than 30 weeks gestational age (GA) at birth (22 with low-grade IVH, 20 without). These infants were divided into two birth groups depending on GA, and we then compared the presence and absence of IVH which was diagnosed by cerebral ultrasound (CUS) within 10 days after birth or conventional magnetic resonance imaging (MRI) at term-equivalent age in each group. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) at the superior cerebellar peduncle (SCP), middle cerebellar peduncle (MCP), motor tract, and sensory tract were measured. In the SCP, preterm born infants with IVH had lower FA values compared with infants without IVH. In particular, younger preterm birth with IVH had lower FA values in the SCP and motor tract and higher ADC values in the MCP. Low-grade IVH impaired cerebellar and cerebral WM, especially in the SCP. Moreover, younger preterm infants exhibited greater disruptions to cerebellar WM and the motor tract than infants of older preterm birth. (orig.)

    Full Text Available Bleeding complications of dengue hemorrhagic fever such as epistaxis, gum bleeding, gastrointestinal bleeding, hypermenorrhea, hematuria, and thrombocytopenia have been documented. A 49-year-old female presented with complaints of intermittent high-grade fever for the past 4 days, lower abdominal pain and altered sensorium for 1 day. Laboratory investigations revealed severe anemia, mild thrombocytopenia, hypofibrinogenemia, and positive dengue serology. Emergency ultrasound examination of the abdomen revealed a possible rapidly expanding hematoma from the inferior epigastric artery and suggested urgent computed tomography (CT angiogram for confirmation of the same. CT angiogram was confirmatory, and patient underwent emergency embolization of the right inferior epigastric artery. We report the first case of inferior epigastric hemorrhage and rectus sheath hematoma as a consequence of dengue.

    Full Text Available Thirty-three cases of hypertensive cerebellar hemorrhage were involved in this survey, with the bleeding volume over 10 ml. All of them were given external ventricular drainage and then taken continuous monitoring of intracranial pressure (ICP after admission. Within 7-24 h after the onset, they all underwent trepanation and drainage under local anesthesia. In the same period, another 33 cases of cerebellar hemorrhage patients were collected as the control, who met the inclusion criteria and were treated with conventional posterior fossa decompressive craniotomy. As results, the total efficiency of the drilling group was 81.82% (27/33, which was much better than the control group (63.64%, 21/33.

    Aortic coarctation complicated with spinal artery aneurysm rupture is exceptionally rare and can be source of intraspinal hemorrhage with markedly poor prognosis. A 21-year-old man visited the emergency department because of chest and back pain along with immobility of bilateral lower limbs immediately after he woke up in the morning. Complete flaccid paraplegia and hypoesthesia in dermatome below bilateral T3 level and pain over axial region from neck to lumbar region were noted. A computed tomography excluded aortic dissection. Magnetic resonance imaging revealed a fusiform lesion involving the anterior epidural space from C7 to T2 level suspected of epidural hemorrhage, causing compression of spinal cord. He started intravenous corticosteroid but refused operation concerning the surgical benefits. Severe chest pain occurred with newly onset right bundle branch block that developed the other day. Coronary artery angiography revealed myocardial bridge of left anterior descending coronary artery at middle third and coarctation of aorta. He underwent thoracic endovascular aortic repair uneventfully. The patient was hemodynamically stable but with slow improvement in neurologic recovery of lower limbs. Aortic coarcation can cause paralysis by ruptured vascular aneurysms with spinal hemorrhage and chest pain that mimics acute aortic dissection. A history of hypertension at young age and aortic regurgitated murmurs may serve as clues for further diagnostic studies. Cautious and prudent evaluation and cross disciplines cares are essential for diagnosis and successful management of the disease.

    Full Text Available Objective: Neonatal subgaleal hemorrhage is a rare but potentially lethal complication of instrumental delivery, particularly vacuum extraction. It is often underreported and underdiagnosed. The prevalence of subgaleal hemorrhages varies from 0.04 to 0.15% of all deliveries. We describe two cases of severe subgaleal hemorrhage (SGH and review the key elements of identification and treatment. Case report: The first case was a female neonate with birth weight 2220gr that was born by vacuum assisted vaginal delivery. At birth, the infant was pale, flaccid with no respiratory effort. She was grossly pale with poor perfusion, lethargic, decreased muscle tone, anemia, and hypovolemic shock. On her head a large fluctuant swelling was seen. She died at 20th hours of age. The second case was a full term male neonate that was born with cesarean section after an unsuccessful 2 to 3 time vacuum extraction. At birth the infant was limp, cyanotic with weak respiratory effort. After 7th hours, a severe fluctuant swelling was found on his head with head circumference of 38.5 cm and ecchymosis around his orbits. He developed anemia and seizure. After successful treatment, he was released from hospital. Conclusion: Increased awareness of SGH should lead to earlier identification, referral and treatment, with resultant improved outcomes.

    Full Text Available AIM:To explore clinical characteristics of supracho-roidal hemorrhage(SCHcomplicated by intraocular surgery and to observe visual prognosis. METHODS:A total of 13 eyes(13 caseswith SCH related to intraocular surgery from June 2005 to June 2015 were included and respectively studied. The age of our cases ranged from 22 to 76. Of all, 4 eyes(31%were concomitant with hypertension, 6 eyes(46%with high myopia and 6 eyes(46%with oculi hypertonia, respectively. Intraoperative expulsive SCH occurred in 8 eyes, while postoperative delayed SCH in 5 eyes. The most SCH(7 eyeshappened during the surgery of removing silicone oil, 4 eyes with SCH were related to extracapsular cataract extraction(ECCE, 1 SCH eye was complicated by ECCE combined with trabeculectomy and 1 SCH eye by lensectomy and vitrectomy. As for treatment, 5 eyes took medication alone, 4 eyes were performed drainage sclerotomy and gas tamponade, while the other 4 eyes were accomplished vitrectomy with adjunctive perfluoro-carbon liquids and silicone oil tamponade. RESULTS:At the 10-month of follow-up, all eyes with SCH were resolved. Except 1 eye with no light perception owing to abandoning treatment, the sights of the other 12 eyes were between light perception and 0.4. CONCLUSION:SCH complicated by intraocular surgery was rare but with devastating outcome. Aged patients, hypertension, high myopia and oculi hypertonia may be risk factors. In addition, surgical methods in the early years were likely correlated to the occurrence of SCH. Certain sight of the patients with SCH may be maintained after positive treatment.

  8. An Unusual Complication of Hypertensive Hemorrhage – Delayed Oculomotor Palsy: Case Report and Literature Review

    Full Text Available We present a case of oculomotor palsy due to hypertensive hemorrhage in the caudate nucleus, with intraventricular extension. To our knowledge, this is the only instance of this complication occurring due to hypertensive hemorrhage. Our patient initially developed headache at the time of her hemorrhage; 8 days later, she developed complete third nerve palsy, which showed improvement at follow-up 4 months later. This was due to tracking of blood into the perimesencephalic cistern. The presence of hemorrhage in the basal cisterns was not visible on the initial CT scans and highlights the role of MRI in evaluating the brainstem for the presence of blood products.

    Recent success with thrombolytic therapy for acute myocardial infarction has stimulated interest in its use for stroke. To determine the hemorrhagic potential of thrombolytic therapy in experimental cerebral infarction, we compared a group of tissue plasminogen activator-treated rabbits (n = 4) with 2 groups of streptokinase-treated rabbits (n = 6 in each), as well as with 3 groups of heparin-treated rabbits (n = 5 in each) and untreated controls (n = 12). Focal cerebral infarction was produced in rabbits by occlusion of the right common carotid and middle cerebral arteries coupled with 2 hours of halothane-induced hypotension. Treatment with heparin or thrombolytic agents began 24 hours after occlusion. One additional group was treated with streptokinase 1 hour after occlusion (n = 6) to determine the hemorrhagic potential of thrombolytic agents in evolving infarction. Rabbits were killed 29-33 hours after occlusion, and brain sections were examined using light microscopy. The results demonstrate that microscopic hemorrhage is frequently present in infarcted tissue irrespective of treatment. Gross cerebral hemorrhage did not occur in untreated rabbits or in rabbits treated with streptokinase 1 hour after occlusion. Only rabbits treated with streptokinase, tissue plasminogen activator, or excessive doses of heparin 24 hours after occlusion, at a time when cerebral infarction was well established, exhibited gross hemorrhage in the area of infarction. These data suggest that treatment of ischemic stroke with thrombolytic agents carries an increased risk of cerebral hemorrhage unless the agents are given early after the onset of symptoms.

    Full Text Available Cerebellar injury is increasingly recognized through advanced neonatal brain imaging as a complication of premature birth. Survivors of preterm birth demonstrate a constellation of long-term neurodevelopmental deficits, many of which are potentially referable to cerebellar injury, including impaired motor functions such as fine motor incoordination, impaired motor sequencing and also cognitive, behavioral dysfunction among older patients. This paper reviews the morphogenesis and histogenesis of the human and rodent developing cerebellum, and its more frequent injuries in preterm. Most cerebellar lesions are cerebellar hemorrhage and infarction usually leading to cerebellar abnormalities and/or atrophy, but the exact pathogenesis of lesions of the cerebellum is unknown. The different mechanisms involved have been investigated with animal models and are primarily hypoxia, ischemia, infection, and inflammation Exposure to drugs and undernutrition can also induce cerebellar abnormalities. Different models are detailed to analyze these various disturbances of cerebellar development around birth.

    Full Text Available OBJECTIVE: To correlate the incidence of hemorrhage and thrombosis to bleeding time (BT and platelet aggregation in 27 consecutive patients with myeloproliferative diseases (MPD. DESIGN: Retrospective study. SETTING: Public tertiary referral center. PATIENTS: Eighteen patients with chronic myelogenous leukemia (CML, 5 with polycytemia vera (PV, 2 with essential thrombocytemia (ET and 2 with idiopathic myelofibrosis (MF. Duke's BT and epinephrine-induced platelet aggregation were performed on the patients and on 10 healthy individuals. RESULTS: Eleven patients presented symptoms (41 %: 9 with hemorrhage (33% and 5 with thrombosis (19%.There were less symptomatic patients in the CML group (28% than in the other MPD (67%, without statistical significance (Fisher, p=0.06. Duke's BT was longer in symptomatic patients (Mann-Whitney, p<0.05. Platelet aggregation was abnormal in 7 patients (26% and 71% of them were symptomatic (Fisher, p = 0.07. CONCLUSIONS: The high incidence of bleeding and thrombosis in patients with MPD was related to prolonged BT, but not to platelet aggregation abnormalities.

    We report a case of a 39-year-old man who presented with a nonfunctioning pituitary macroadenoma which extended into the suprasellar region. He underwent a transcranial resection of the tumor followed eight months later by transsphenoidal surgery for the residual tumor. Postoperatively he developed massive subarachnoid and intraventricular hemorrhage. A cerebral angiogram revealed a leaking anterior communicating artery aneurysm which was not seen on the computed tomography angiography and magnetic resonance angiography before the surgery. Complications of transsphenoidal surgery, particularly vascular hemorrhagic complications, and risk of rupture of undetected aneurysms are discussed.

    The purpose of this study was to evaluate the value of 320-detector row CT used to detect crossed cerebellar diaschisis (CCD) in patients with unilateral supratentorial spontaneous intracerebral hemorrhage (SICH). We investigated 62 of 156 patients with unilateral supratentorial SICH using 320-detector row CT scanning. Regional cerebral blood flow (rCBF), cerebral blood volume (rCBV), mean transit time (rMTT), and time to peak (rTTP) levels were measured in different regions of interest (ROIs) that were manually outlined on computed tomography perfusion (CTP) for the cerebrum, including normal-appearing brain tissue that surrounded the perilesional low-density area (NA) and the perihematomal low-density area (PA) in all patients and the cerebellum (ipsilateral and contralateral) in CCD-positive patients. Of 62 cases, a total of 14 met the criteria for CCD due to cerebellar perfusion asymmetry on CTP maps. In the quantitative analysis, significant differences were found in the perfusion parameters between the contralateral and ipsilateral cerebellum in CCD-positive cases. No significant differences were found between the CCD-positive group and the CCD-negative group according to the hematoma volume, NIHSS scores, and cerebral perfusion abnormality (each P > 0.05). The correlation analysis of the degree of NA, PA perfusion abnormality, and the degree of CCD severity showed negative and significant linear correlations (R, -0.66∝-0.56; P < 0.05). 320-detector row CT is a robust and practicable method for the comprehensive primary imaging work-up of CCD in unilateral supratentorial SICH patients.

    To assess risk factors and the extent of pulmonary hemorrhage complicating radiofrequency ablation (RFA) of pulmonary neoplasms. This retrospective study involved 248 ablation sessions for lung tumors (20 primary lesions and 228 metastatic lesions) in 164 patients (mean age 59.7 years, SD: 10.2). Both unipolar and bipolar radiofrequency systems were used under CT fluoroscopic guidance. Extent and underlying factors associated with development of pulmonary hemorrhage were analyzed. Incidence of intra-parenchymal pulmonary hemorrhage, pleural effusion, and hemoptysis were 17.7% (44/248 sessions), 4% (8/248 sessions), and 16.1% (40/248 sessions), respectively. Death because of massive bleeding occurred in one session (0.4%). Significant risk factors associated with intra-parenchymal hemorrhage included: lesions of <1.5 cm diameter (P = 0.007); basal and middle lung zone lesions (P = 0.026); increased needle track distance traversing the lung parenchyma >2.5 cm (P = 0.0017); traversing pulmonary vessels in the track of ablation (P < 0.001); and the use of multi-tined electrodes (P = 0.004). Concomitant incidence of pulmonary hemorrhage and pneumothorax was 29.2% (14/48 sessions). While typically safe, RFA of pulmonary neoplasms can result in pulmonary hemorrhage ranging from mild to life-threatening. Management of this complication is mainly preventive through adequate patient selection for ablation therapy and exclusion of technically avoidable risk factors. (orig.)

    2014-01-01

    Full Text Available The authors present two cases of intraventricular hemorrhage (IVH believed to be a result of epidural blood patching. The first was a 71-year-old woman who had new onset of nontraumatic IVH on computed tomography (CT scan after undergoing an epidural blood patch (EBP. This amount of intraventricular blood was deemed an incidental finding since it was of very small volume to account for her overall symptoms. The second patient, a 29-year-old woman, was found to have nontraumatic IVH three days after undergoing an EBP. This was seen on CT scan of the head for workup of pressure-like headaches, nausea, vomiting, and absence seizures. Conservative management was followed in both instances. Serial CT scan of the head in our first patient displayed complete resolution of her IVH. The second patient did not have follow-up CT scans because her overall clinical picture had improved significantly. This highlights a potential sequel of EBP that may be observed on CT scan of the head. In the event that IVH is detected, signs and symptoms of hydrocephalus should be closely monitored with the consideration for a future workup if warranted by the clinical picture.

    Systemic complications secondary to subarachnoid hemorrhage from an aneurysm are common (40%) and the mortality attributable to them (23%) is comparable to mortality from the primary lesion, rebleeding, or vasospasm. Although nonneurologic medical complications are avoidable, they worsen the prognosis, lengthen the hospital stay, and generate additional costs. The prevention, early detection, and appropriate treatment of systemic complications will be essential for managing the individual patient's case. Treatment should cover major symptoms (headache, nausea, and dizziness) and ambient noise should be reduced, all with the aim of achieving excellence and improving the patient's perception of quality of care.

    Full Text Available Introduction. Hemorrhagic fever with renal syndrome (HFRS is acute infective multisystemic disease followed by febrility, hemorrhages and acute renal insufficiency. Bleeding in the anterior pituitary lobe leading to tissue necrosis occurs in acute stage of severe clinical forms of HFRS, while atrophy of the anterior pituitary lobe with diminution of the gland function occurs after recovery stage. Case report. We presented a patient with the development of chronic renal insufficiency and hypopituitarism as complication that had been diagnosed six years after Hantavirus infection. Magnetic resonance of the pituitary gland revealed atrophy and empty sella turcica. Conclusion. Regarding frequency of this viral infection and its endemic character in some parts of our country partial and/or complete loss of pituitary function should be considered during the late stage of HFRS.

    supratentorial craniotomy is obviously different from that of hypertensive cerebellar hemorrhage. From the shape or extension of the hemorrhage, the main vessels of hemorrhage are the superior vermian vein and their tributaries damaged by stretching and tearing of these vessels. These vessels are not demonstrable in the angiogram, therefore there is no evidence for this hypothesis and the etiology is still unclear. There is no doubt, however, that there was a disturbance of venous circulation in this complication. We would like to emphasize the possibility of this complication. Patients who show signs of difficulty in awaking from anesthesia or the development of new neurological deficits not attributed to direct operative procedure after supratentorial craniotomy must be evaluated early, with adequate imaging including the posterior fossa.

    Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula. TAE is a minimally invasive procedure with a low rate of complications, which preserves future fertility. Knowledge of causes of PPH, potential risks, and limitations of TAE is essential for a timely decision, optimizing TAE, preventing irreversible complications, avoiding hysterectomy, and ultimately preserving fertility.

    Introduction We sought to determine if monitoring heart rate variability (HRV) would enable preclinical detection of secondary complications after subarachnoid hemorrhage (SAH). Methods We studied 236 SAH patients admitted within the first 48 hours of bleed onset, discharged after SAH day 5, and had continuous electrocardiogram records available. The diagnosis and date of onset of infections and DCI events were prospectively adjudicated and documented by the clinical team. Continuous ECG was collected at 240 Hz using a high-resolution data acquisition system. The Tompkins Hamilton algorithm was used to identify R-R intervals excluding ectopic and abnormal beats. Time, frequency, and regularity domain calculations of HRV were generated over the first 48 hours of ICU admission and 24 hours prior to the onset of each patient's first complication, or SAH day 6 for control patients. Clinical prediction rules to identify infection and DCI events were developed using bootstrap aggregation and cost sensitive meta-classifiers. Results The combined infection and DCI model predicted events 24 hours prior to clinical onset with high sensitivity (87%) and moderate specificity (66%), and was more sensitive than models that predicted either infection or DCI. Models including clinical and HRV variables together substantially improved diagnostic accuracy (AUC 0.83) compared to models with only HRV variables (AUC 0.61). Conclusions Changes in HRV after SAH reflect both delayed ischemic and infectious complications. Incorporation of concurrent disease severity measures substantially improves prediction compared to using HRV alone. Further research is needed to refine and prospectively evaluate real-time bedside HRV monitoring after SAH. PMID:24610353

    Examination of patients, suffering gastroduodenal ulcer, complicated by hemorrhage, was conducted, using clinical, microbiological, immunohistochemical methods and chromatomassspectrography. Enhanced activity of inducible NO-synthase, contamination of periulcer zone with microorganisms Klebsiella pneumoniae, Streptococcus beta-haemoliticus, enhancement of contents of catecholamines and serotonin in the blood serum were revealed. These changes are most expressed in severe blood loss, unstable local endoscopic hemostasis, high risk of a recurrent hemorrhage occurrence. The data obtained permit to prognosticate severity of a pathologic process course and to improve the treatment programe.

    OBJECTIVE Early rehabilitation is effective in an array of acute neurological disorders but it is not established as part of treatment guidelines after aneurysmal subarachnoid hemorrhage (aSAH). This may in part be due to the fear of aggravating the development of cerebral vasospasm, which is the most feared complication of aSAH. The aim of this study was to evaluate the effect of early rehabilitation and mobilization on complications during the acute phase and within 90 days after aSAH. METHODS This was a prospective, interventional study that included patients with aSAH at the neuro-intermediate ward after aneurysm repair. The control group received standard treatment, whereas the early rehab group underwent early rehabilitation and mobilization in addition to standard treatment. Clinical and radiological characteristics of patients with aSAH, progression in mobilization, and treatment variables were registered. The frequency and severity of cerebral vasospasm, cerebral infarction acquired in conjunction with the aSAH, and acute and chronic hydrocephalus, as well as pulmonary and thromboembolic complications, were compared between the 2 groups. RESULTS Clinical and radiological characteristics of patients with aSAH were similar between the groups. The early rehab group was mobilized beginning on the first day after aneurysm repair. The significantly quicker and higher degree of mobilization in the early rehab group did not increase complications. Clinical cerebral vasospasm was not as frequent in the early rehab group and it also tended to be less severe. Each step of mobilization achieved during the first 4 days after aneurysm repair reduced the risk of severe vasospasm by 30%. Acute and chronic hydrocephalus were similar in both groups, but there was a tendency toward earlier shunt implantation among patients in the control group. Pulmonary infections, thromboembolic events, and death before discharge or within 90 days after the ictus were similar between the 2

    Antiphospholipid syndrome (APS) is an autoimmune condition involving arterial and venous thrombosis. An unusual APS variant, catastrophic antiphospholipid syndrome (CAPS), includes rapid multi-organ failure from widespread small vessel thrombosis. Central nervous system complications arise in one-third of CAPS patients. In rare cases, CAPS co-manifests with cerebellar hemorrhage presenting a neurosurgical emergency. We present a 65-year-old woman with CAPS-related cerebellar hematoma, co-morbid idiopathic thrombocytopenic purpura, deep vein thrombosis and altered mental status, with treatment complicated by thrombocytopenia. The patient suddenly deteriorated, secondary to a cerebellar subdural hematoma, and underwent decompression and excision of the hematoma. After recovery in the intensive care unit, she developed a new spontaneous epidural hematoma requiring additional surgery. Management of these patients is hematologically complex and often requires a multi-disciplinary team of physicians. This patient provides an important learning point for clinicians - consider CAPS when hemorrhage and thrombosis are present.

    The CT/MRI brain findings and sequelae of intracranial hemorrhage resulting from traumatic breech and vacuum delivery of 16 term newborn infants are presented. Eleven infants were vacuum extracted, while the remaining five infants were delivered breech. Except for three breech-delivered infants who had intraventricular hemorrhage, the location and nature of hemorrhage were similar in both groups. Nine of the 11 vacuum-extracted babies showed complete resolution of hemorrhage on follow-up examination. None of the breech cases had a normal outcome. All five of the latter group had hydrocephalus, and one case each demonstrated porencephaly and encephalomalacia. (orig.). With 3 figs., 3 tabs.

    Diffuse alveolar hemorrhage after percutaneous coronary intervention (PCI) is a rare complication. The diagnosis is difficult and can mimic by clinical and radiological features other diagnosis as pneumopathy. We herein report the case of a 63-year-old female admitted to the hospital for ST elevation myocardial infarction. The patient underwent PCI and received dual antiplatelet therapy. Four days later, she developed dyspnea, hemoptysis and fever. Clinical, radiological and biological findings oriented to a pneumopathy and the patient received the treatment for it. Later and because of the non improvement, a thoracic computed tomography was performed and revealed patchy areas of ground-glass opacity consistent with a diffuse pulmonary hemorrhage. The combination therapy with aspirin and clopidogrel was therefore the most likely cause. Although the dual antiplatelet combination reduces systemic ischemic events after PCI, it is associated with increased risk of nonfatal and sometimes fatal bleeding. Hence the necessity of close and careful observation to watch for possible fatal complications.

    Hereditary hemorrhagic telangiectasia (HHT) is a rare but life-threatening disease characterized by multi system telangiectasias and arteriovenous malformations (AVM). Complications in adults have been reported extensively, but neonatal (NN) complications have only been published in incidental case reports. In this paper, we present a literature review on NN pulmonary AVM related to HHT, following our own experience with a NN death due to this disease. As prenatal diagnosis of pulmonary AVM is feasible, we recommend that a family history of HHT should be an indication for expertise prenatal anomaly scanning, in order to organise optimal NN support at birth.

    Life-threatening hemorrhage rarely occurs from the portal vein following blunt hepatic trauma.Traditionally,severe portal bleeding in this setting has been controlled by surgical techniques such as packing,ligation,and venorrhaphy.The presence of portal hypertension could potentially increase the amount of hemorrhage in the setting of blunt portal vein trauma making it more difficult to control.This case series describes the use of indirect carbon dioxide portography to identify portal hemorrhage.Furthermore,these cases illustrate attempted endovascular treatment utilizing a transjugular intrahepatic portosystemic shunt in one scenario and transmesocaval shunt coiling of a jejunal varix in the other.

  20. A complicated case of antepartum eclamptic fit with HELLP syndrome, acute renal failure and multiple intracranial hemorrhages: A mortality report

    Full Text Available HELLP is an acronym for hemolysis, elevated liver enzymes and low platelets count, affecting 0.2–12% of all pregnancies or 4–12% of those with preeclampsia. The maternal mortality reported from the literature is up 4% due to disseminated intravascular coagulation, placental abruption, acute renal failure, eclampsia, and cerebral hemorrhage. A 20 year old, G2P1, at 36 weeks of gestation, was referred to our hospital because of postictal coma state with bilateral mydriasis and epistaxis due to repeated antepartum eclamptic fits. Elevated blood pressure level 170/110 mmHg was accompanied with massive proteinuria. Cesarean section was performed and female newborn were delivered. Laboratory findings were characteristic of preeclampsia, HELLP syndrome and renal failure. The patient developed an intraventricular hematoma and an intracerebral hemorrhage with subarachnoid one, which were not suitable to neurosurgical treatment. The patient died from refractory hemolytic anemia, spontaneous bleeding of multiple organs, renal failure and intracranial hemorrhage. Preeclampsia, HELLP syndrome, and acute fatty liver of pregnancy might overlap and be associated with potentially fatal complications, including intracranial hemorrhage, as in the present case. Early detection and diagnosis are crucial to ensure appropriate management and treatment success.

  1. Visual Loss, Retinal Hemorrhages, and Optic Disc Edema Resulting From Thiamine Deficiency Following Bariatric Surgery Complicated by Prolonged Vomiting

    Lawton, Andrew W.; Frisard, Nicholas E.

    2017-01-01

    Background: Vision loss resulting from thiamine deficiency is a recognized complication of bariatric surgery. Most patients with such vision loss have Wernicke encephalopathy with characteristic changes seen on neuroimaging. Other patients may have retinal hemorrhages, optic disc edema, and peripheral neuropathy without Wernicke encephalopathy. The risk for thiamine deficiency is potentiated by the presence of prolonged vomiting. Case Report: A 37-year-old female presented with abrupt onset of vision loss and peripheral neuropathy following bariatric surgery. She had a history of prolonged vomiting postoperatively. Examination of the posterior segment of the eye revealed optic disc edema and large retinal hemorrhages bilaterally. Metabolic workup demonstrated thiamine deficiency. She responded quickly to parenteral thiamine therapy with recovery of normal vision and resolution of ophthalmologic findings. Conclusion: Patients who undergo bariatric surgery and have a thiamine deficiency can present with visual symptoms and ophthalmologic findings only visible by fundoscopy prior to developing more severe and potentially irreversible complications from the vitamin deficiency. Early detection of intraocular changes resulting from thiamine deficiency and initiation of therapy could prevent more devastating neurologic manifestations. Our case supports the consideration of a prospective study aimed at determining the true incidence of ocular and visual changes such as retinal hemorrhage, optic disc edema, and peripapillary telangiectasia in patients following bariatric surgery.

    This study aimed to investigate the therapeutic effects of craniocervical decompression with duraplasty and cerebellar tonsillectomy for the treatment of Chiari malformation-I with syringomyelia (CM I-SM). From January 2005 to December 2011, 127 patients with CM I-SM underwent craniocervical decompression with duraplasty and cerebellar tonsillectomy and the therapeutic effects of these surgeries were evaluated using Tator scores. No patient in this study died or showed disease deterioration after the surgery. Re-examination by magnetic resonance imaging (MRI) showed that the cisterna magna was obviously larger after the operation in all but one patient. Moreover, syringomyelia (SM) was reduced in 76 patients. CM I-SM symptoms disappeared or decreased in 112 patients after following discharge. Follow-up was conducted in 84 of the patients and 79 of these patients exhibited improved symptoms. A second MRI re-examination showed that the cisterna magna was successfully constructed in 44 patients; 42 of these patients showed further eliminated or obviously reduced SM. Craniocervical decompression with duraplasty and cerebellar tonsillectomy achieved favorable therapeutic effects. Thus, craniocervical decompression with duraplasty and cerebellar tonsillectomy is a rational surgical approach with beneficial clinical effects. The proposed approach may have useful applications in the treatment of CM I-SM.

    Full Text Available Russell′s viper (Daboia russelli bites are well known to cause bleeding complications. However, thrombotic complications are rare. We present the case details of a female who was bitten by a Russell′s viper (Daboia russelli in her village. She then developed features of envenomation in the form of hemorrhagic episodes. She received 27 vials of polyvalent anti-snake venom to which the hemorrhagic complications responded. After about 48 h of the bite she developed features of cerebellar infarct along with pulmonary edema which was in all probability neurogenic in origin. She was managed with mechanical ventilation and extra ventricular drainage with good recovery. We discuss the likely pathogenesis of the infarct and pulmonary edema occurring in a patient with viper bite and other features of envenomation.

    Full Text Available Antiphospholipid syndrome is a systemic autoimmune disease with thrombotic tendency. Consensus guidelines for pregnancy with antiphospholipid syndrome recommend low-dose aspirin combined with unfractionated or low-molecular-weight heparin because antiphospholipid syndrome causes habitual abortion. We report a 36-year-old pregnant woman diagnosed with antiphospholipid syndrome receiving anticoagulation treatment. The patient developed left abdominal pain and gross hematuria at week 20 of pregnancy. An initial diagnosis of left ureteral calculus was made. Subsequently abdominal-pelvic computed tomography was required for diagnosis because of the appearance of severe contralateral pain. Computed tomography revealed serious renal hemorrhage, and ureteral stent placement and pain control by patient-controlled analgesia were required. After treatment, continuance of pregnancy was possible and vaginal delivery was performed safely. This is the first case report of serious renal hemorrhage in a pregnant woman with antiphospholipid syndrome receiving anticoagulation treatment and is an instructive case for urological and obstetrical practitioners.

    Fatal acute tubular necrosis occurred in 1 patient in whom intravesical formalin was used to control massive persistent hemorrhage from radiation cystitis. A suggestion is made to monitor blood formic acid levels and institute prompt dialysis whenever these exceed 80 mg per 100 ml to avert such a catastrophe. Intravenous sodium bicarbonate appears to be indicated prophylactically in combating the associated metabolic acidosis due to absorbed formic acid.

    Conclusions: Anterior cervical spine surgery is a safe approach and is associated with few major esophageal/pharyngeal complications, which most commonly include transient dysphagia and dysphonia. If symptoms persist, patients should be assessed for esophageal/pharyngeal defects utilizing appropriate imaging studies. Notably, even if the major complications listed above are adequately treated, optimal results are in no way guaranteed.

  8. Infarction of the entire corpus callosum as a complication in subarachnoid hemorrhage: A case report

    Directory of Open Access Journals (Sweden)

    Satoru Takahashi, M.D.

    2017-03-01

    Full Text Available The corpus callosum is the major commissural pathway connecting the cerebral hemispheres. This pathway receives its blood supply from anterior communicating artery, pericallosal artery, and posterior pericallosal artery. However, in some cases, the entire corpus callosum is supplied by median callosal artery; thus, occlusion of this artery can lead to infarction of the entire corpus callosum. Few reports have described this type of infarction, and no reports after subarachnoid hemorrhage (SAH exist. Here, we report on a 42-year-old female who was diagnosed with SAH after two aneurysms were discovered in bifurcation of left anterior cerebral artery (A1-A2. After successful clipping was performed, the patient was alert and had no neurological deficits; moreover, the computed tomography images that were acquired after the operation showed no evidence of infarction. Nine days after admittance to the hospital, drowsiness and weakness of the left limbs with brain swelling appeared and decompressive hemi-craniectomy was performed. Diagnostic cerebral angiography revealed vasospasms in both anterior and middle cerebral arteries, thus fasudil hydrochloride was administered intra-arterially. While blood flow in all arteries improved, diffusion-weighted magnetic resonance imaging detected infarction along the entire length of the corpus callosum and in the medial region of the right frontal lobe. We believe this infarction was due to secondary ischemia of median callosal artery. This case reminded us of the anatomical variation wherein median callosal artery is the sole blood supply line for the corpus callosum and demonstrated that infarction of the entire corpus callosum is possible.

    Aim of this paper is to present and discuss a case of a delayed cerebellar parenchymal hemorrhage developing after L/P shunt placement with a NPH patient. A hypertensive patient admitted to our clinic with a diagnosis of NPH. The patient was placed a pressure adjustable L/P shunt without any surgical complication. He was discharged with an uneventful period. The patient was admitted to the emergency clinic of our hospital with a 1.5 × 1.5 cm diameter hematoma at the left cerebellar hemisphere on 2 days after his discharge. CSF drainage by an L/P shunt can generate intracerebellar hemorrhages especially in hypertensive patients. PMID:27695558

    Full Text Available Background/Aim. Up-to-date treatment of acute myocardial infarction (AIM has been based on as early as possible establishment of circulation in ischemic myocardium whether by the use of fibrinolythic therapy and/or urgent coronary intervention which significantly changes the destiny of patients with AMI, but also increases the risk of bleeding. The aim of this study was to compare coronary flow and bleeding complications in patients with acute myocardial infarction with ST-elevation (STEMI after administration of alteplase or streptokinase. Methods. The study included 254 patients with STEMI. The group I (n = 174 received streptokinase, and the group II (n = 80 received alteplase. We followed frequency of complications such as bleeding and hypotension in the investigated groups of patients, based on the TIMI classification of bleeding, as well as the transience of infarction artery in accordance with TIMI flow. Results. The patients with myocardial infarction after administration of alteplase had statistically significantly higher coronary flow (TIMI- 3, 72.5% as compared to the patients who received streptokinase, 39.2%. Hypotension as complication of fibrynolythic therapy administration occurred in a significantly higher percentage in the group of patients who received streptokinase. There was no statistically significant difference in the appearance of major bleeding in the groups of patients who received streptokinasis and alteplase (6.9% and 7.5%, respectively. Also, there was no difference in the appearance of minor and minimal bleeding among the investigated groups of patients. Conclusion. It was shown that alteplase in a higher number of patients provided TIMI-3 coronary flow as compared to streptokinese. In comparison with streptokinase, a combination of alteplase, enoxaparin and double antiplatelet therapy enabled earlier achievement of coronary flow through previously blocked coronary artery that was more complete (higher frequency of

    Mestdagh, H

    1982-03-11

    The author reported an unusual complication of iliac bone transplantation for grafting of a tibial pseudarthrosis. In a patient having anticoagulant therapy, a large iliac haematoma developed in the donor site and extended deep to the iliacus muscle and through the osteomuscular gap into the retroperitoneal space. Moreover it spread downwards and entrapped the femoral nerve as it lies behind the iliac fascia, above the inguinal ligament. Both a paralytic ileus and a femoral nerve injury commanded surgical exploration through an oblique iliac approach; emptying of the clotted haematoma, section of the inguinal ligament and liberation of the femoral nerve enable to avoid definitive sequelae to the quadriceps but the time required is varying: three years after the accident, recovery is not complete in the operated patient probably owing to delayed surgery (three weeks).

    Full Text Available Portal hypertension in children represents a particular diagnostic and management challenge for several reasons: (1 treatment outcomes should be evaluated in relationship with a long-life expectancy, (2 pediatric patients with portal hypertension constitute an heterogeneous population, both in terms of individual characteristics and diversity of liver diseases; making comparison between treatment outcomes very difficult, (3 application of techniques and procedures developed in adult patients (v.gr. TIPS face size limitations in small children, and (4 absence of data from well-controlled trials in children forces pediatric specialists to adapt results obtained from adult cohorts suffering from diseases such as HCV and alcoholic cirrhosis. Despite those limitations, substantial progress in the treatment of children with portal hypertension has been achieved in recent years, with better outcomes and survival. Two main factors influence our therapeutic decision: age of the patient and etiology of the liver disease. Therefore, diagnosis and treatment of complications of portal hypertension in children need to be described taking such factors into consideration. This paper summarizes current knowledge and expert opinion.

    AIM: To explore the dynamic changes in the pressure of the lateral ventricle during acute brainstem hemorrhage and the changes of neural discharge of vagus nerve under the load of intracranial hypertension, so as to analyze their effects on the congestive degree of intestinal mucous membrane and the morphologic changes of intestinal mucous membrane. METHODS: An operation was made to open the skull to obtain an acute brainstem hemorrhage animal model. Microcirculatory microscope photography device and video recording system were used to determine the changes continuously in the caliber of jejunal mesenteric artery during brainstem hemorrhage and the changes with time in the congestion of jejunal mucosal villi. We used HE stain morphology to analyze the changes of duodenal mucosal villi. A recording electrode was used to calculate and measure the electric discharge activities of cervical vagus nerve. RESULTS: (1) We observed that the pressure of lateral cerebral ventricle increased transiently during acute brainstem hemorrhage; (2) The caliber of the jejunal mesenteric artery increased during brainstem hemorrhage. Analysis of red color coordinate values indicated transient increase in the congestion of jejunal mucous membrane during acute brainstem hemorrhage; (3) Through the analysis of the pathologic slice, we found enlarged blood vessels, stagnant blood, and transudatory red blood cells in the duodenal submucous layer; (4) Electric discharge of vagus nerve increased and sporadic hemorrhage spots occurred in duodenal mucous and submucous layer, when the lateral ventricle was under pressure. CONCLUSION: Brainstem hemorrhage could cause intracranial hypertension, which would increase the neural discharge of vagus nerve and cause the transient congestion of jejunal mucous membrane. It could cause hyperemia and diffused hemorrhage in the duodenal submucous layer 48 h after brainstem hemorrhage. PMID:15786536

    Inherited cerebellar ataxias constitute a complicated and heterogeneous group of neurodegenerative disorders affecting the cerebellum and/or spinocerebellar tract, spinal cord and peripheral nerves. A peripheral neuropathy is frequently seen in inherited cerebellar ataxias although it rarely reveals the disease. Moreover, the peripheral neuropathy is helpful for the diagnostic procedure and contributes to the functional prognosis of the disease. Thus, electroneuromyography is essential in the algorithm for the diagnosis of inherited cerebellar ataxias, as well as brain MRI (looking especially for cerebellar atrophy) and the assessment of several biomarkers (alpha-foetoprotein, vitamin E, albumin, LDL cholesterol, lactic acid, phytanic acid).

Materials and methods: Retrospective study included CT-guided percutaneous lung biopsies in 650 consecutive patients (407 males, 243 females; mean age 54.6 years, SD: 5.2) from November 2008 to June 2013. Patients were classified according to lung biopsy technique in coaxial group (318 lesions) and non-coaxial group (332 lesions). Exclusion criteria for biopsy were: lesions <5 mm in diameter, uncorrectable coagulopathy, positive-pressure ventilation, severe respiratory compromise, pulmonary arterial hypertension or refusal of the procedure. Risk factors for pulmonary hemorrhage complicating lung biopsy were classified into: (a) patient's related risk factors, (b) lesion's related risk factors and (d) technical risk factors. Radiological assessments were performed by two radiologists in consensus. Mann–Whitney U test and Fisher's exact tests for statistical analysis. p values <0.05 were considered statistically significant. Results: Incidence of pulmonary hemorrhage was 19.6% (65/332) in non-coaxial group and 22.3% (71/318) in coaxial group. The difference in incidence between both groups was statistically insignificant (p = 0.27). Hemoptysis developed in 5.4% (18/332) and in 6.3% (20/318) in the non-coaxial and coaxial groups respectively. Traversing pulmonary vessels in the needle biopsy track was a significant risk factor of the development pulmonary hemorrhage (incidence: 55.4% (36/65, p = 0.0003) in the non-coaxial group and 57.7% (41/71, p = 0.0013) in coaxial group). Other significant risk factors included: lesions of less than 2 cm (p value of 0.01 and 0.02 in non-coaxial and coaxial groups respectively), basal and middle zonal lesions in comparison to upper zonal lung lesions (p = 0.002 and 0.03 in non-coaxial and coaxial groups respectively), increased lesion

    Cerebellar mutism (anarthria) is a well-described complication of posterior fossa tumor resection. It is accompanied by a characteristic behavior including irritability and autistic features. This syndrome is typically reversible within days to months. Underlying pathophysiology is unknown. We describe two children who presented with a similar clinical finding after nonsurgical cerebellar involvement, hemolytic-uremic syndrome in one and cerebellitis in the other. Postmortem pathologic findings in the first patient indicated cerebellar ischemic necrosis. Single-photon emission computed tomography in the second patient revealed diffuse cerebellar hypoperfusion with no supratentorial abnormalities, refuting a phenomenon of diaschisis between cerebellar and frontal connections. These findings confirm that this clinical syndrome may occur in a nonsurgical, nontraumatic context. They are consistent with recent integrative hypotheses explaining cerebellar anarthria.

    We report a case of rapidly progressive glomerulonephritis caused by anti-glomerular basement membrane (anti-GBM) antibodies that progressed to end-stage renal disease in a 67-year-old woman with diabetes. Intensive combined immunosuppressive therapy with methylprednisolone bolus, oral prednisone, and cyclophosphamide led to negativity of anti-GBM antibodies but was not able to restore renal function. After 28 months of hemodialysis, the patient suddenly presented with pulmonary hemorrhage. In this setting, high levels of myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody (ANCA) and negative anti-GBM antibodies were found. Therapy with oral prednisone and cyclophosphamide led to resolution of pulmonary hemorrhage and negativity of MPO-ANCA.

    Full Text Available La trombolisis se usa como estrategia de reperfusión coronaria en el infarto agudo de miocardio. El sangrado es su principal complicación; la mayoría ocurre en los sitios de accesos venosos y es leve, pero también pueden presentarse hemorragia gastrointestinal, retroperitoneal, genitourinaria, pulmonar y a nivel del sistema nervioso central, episodios estos generalmente de mayor gravedad y a veces fatales. Se describe aquí el caso de un paciente que recibió terapia trombolítica con estreptoquinasa como tratamiento por un infarto de miocardio, y que posteriormente desarrolló insuficiencia respiratoria aguda, infiltrados pulmonares bilaterales, caída del hematocrito y aumento de la difusión de monóxido de carbono, cuadro compatible con diagnóstico de hemorragia alveolar.Coronary thrombolysis is used as a strategy for coronary reperfusion for acute myocardial infarction. Bleeding is the main complication described. Although most of these events occur at sites of vascular access and are mild, in some cases gastrointestinal, retroperitoneal, genitourinary, lung and central nervous system bleeding may occur. These episodes are usually serious and sometimes fatal. The following report describes the case of a patient who received thrombolytic therapy with streptokinase as a treatment for myocardial infarction. Subsequently he developed acute respiratory failure, bilateral pulmonary infiltrates and fall of hematocrit compatible with diagnosis of alveolar hemorrhage.

    The purpose of this study is to identify the characteristics of brain perfusion measured by arterial spin-labeling magnetic resonance imaging (ASL-MRI) in cerebral hemorrhages. Brain blood flow values (CBF-ASL values) for cerebral and cerebellar hemispheres and segmented cerebral regions were measured by ASL-MRI in 19 putaminal hemorrhage patients and 20 thalamic hemorrhage patients in acute or subacute stages. We assessed the lateralities of CBF-ASL values and the relationships between CBF-ASL values and other imaging findings and clinical manifestations. Both the 19 putaminal hemorrhage patients and the 20 thalamic hemorrhage patients had significantly low CBF-ASL values of the contralateral cerebellum in subacute stage, suggesting that ASL-MRI might delineate crossed cerebellar diaschisis (CCD). Ipsilateral low CBF-ASL values were observed in frontal lobes and thalami with a putaminal hemorrhage and lentiform nuclei, temporal lobes, and parietal lobes with a thalamic hemorrhage, suggesting that ASL-MRI showed the ipsilateral cerebral diaschisis (ICD). In the putaminal hemorrhage patients, the hematoma volume negatively affected both the bilateral cerebellar and cerebral hemispheric CBF-ASL values. In the thalamic hemorrhage patients, a concomitant intraventricular hemorrhage caused low cerebral hemispheric CBF-ASL values. The use of ASL-MRI is sensitive to the perfusion abnormalities and could thus be helpful to estimate functional abnormalities in cerebral hemorrhage patients. (orig.)

  11. The dilemma of complicated shunt valves: How to identify patients with posthemorrhagic hydrocephalus after aneurysmatic subarachnoid hemorrhage who will benefit from a simple valve?

    2016-01-01

    Full Text Available Background: Sophisticated shunt valves provide the possibility of pressure adjustment and antisiphon control but have a higher probability of valve dysfunction especially in a posthemorrhagic setting. The aim of the present study is to analyze the clinical outcome of patients with shunt dependent posthemorrhagic hydrocephalus after aneurysmatic subarachnoid hemorrhage (SAH in order to identify patients who would benefit from a simple differential pressure valve. Methods: From 2000 to 2013, 547 patients with aneurysmatic SAH were treated at our institution, 114 underwent ventricular shunt placement (21.1%. 47 patients with available pre- and post-operative computed tomography scans, and an available follow-up of minimum 6 months were included. In order to measure the survival time which a nonprogrammable differential pressure valve would have had in an individual patient we defined the initial equalized shunt survival time (IESS. IESS is the time until surgical revisions of fixed differential pressure or flow-regulated valves for the treatment of over- or under-drainage as well as re-programming of adjustable valves due to over- or under-drainage. Results: Twenty patients were treated with fixed differential pressure valves, 15 patients were treated with flow-regulated valves, and 12 underwent ventriculoperitoneal (VP shunt placement with differential pressure valves assisted by a gravitational unit. Patients who reacted with remarkable changes of the ventricular width after the insertion of external ventricular drainage (EVD, before shunt placement, showed a significantly longer IESS. Conclusions: Decline of the ventricular width after EVD placement was a predictor for successful VP shunt therapy in the later course of disease. Possibly, this could allow identifying patients who benefit from a simple differential pressure valve or a flow-regulated valve, and thus could possibly avoid valve-associated complications of a programmable valve in the

    Full Text Available Introduction: the patients affected by systemic lupus erythematosus (SLE often suffer gastrointestinal symptoms. The differential diagnosis should contemplate pathology of the gall bladder. We present the case of a patient with hemorrhagic lithiasic cholecystitis and hemobilia. Case report: 24 year old female diagnosed with SLE under treatment with Sintrom®, Dacortin® and Dolquine® that presented acute lithiasic cholecystitis and hemobilia with a distal calculus. Cholecystectomy and aperture of the ductus choledochus were performed allowing to confirm the hemobilia and to extract the calculus. Discussion: the treatment of cholecystitis in the patients with SLE is controversial due to the fact that most reviewed cases have been solved with cholecystectomy, or in other cases with conservative treatment with corticosteroids. We believe that the presence of cholelithiasis in a patient with SLE with pain on the right hypochondrium and ultrasound confirming the suspicion of cholecystitis demands a surgical treatment since the cause may be vascular, lithiasic or combined. Besides, the possible complications will not respond to pharmaceutical treatment.Introducción: los pacientes afectos de lupus eritematoso sistémico (LES sufren con frecuencia síntomas gastrointestinales. Debe incluirse en su diagnóstico diferencial la patología de la vesícula biliar. Presentamos el caso de una paciente con colecistitis alitiásica y hemobilia. Caso clínico: mujer de 24 años diagnosticada de LES en tratamiento con Sintrom®, Dacortin® y Dolquine® que presentó cuadro de colecisititis aguda litiásica y hemobilia, con presencia de cálculo enclavado en papila. Se realizó colecistectomía y apertu-ra del colédoco, lo que permitió confirmar la hemobilia y extracción del cálculo. Discusión: el tratamiento de la colecistitis en los pacientes con LES es controvertido ya que, aunque la mayoría de los casos revisados se han resuelto con la colecistectom

    Neurogenic stunned myocardium is defined as a myocardial injury or dysfunction after neurological insults. It is most commonly reported in patients with subarachnoid hemorrhage, and the presenting symptoms may mimic an acute myocardial infarction or myocarditis. In severe cases, cardiogenic shock and acute pulmonary edema may occur and lead to a devastating event. Therefore, it requires prompt recognition and proper intervention. We herein report the case of a 25-year-old woman who presented to our hospital with the symptoms of acute pulmonary edema, shock, and consciousness disturbance. The diagnosis of encephalitis of cerebellar tonsils complicated with acute hydrocephalus and neurogenic stunned myocardium was made. Detailed neurologic examinations, neuroimaging studies, and characteristic echocardiographic changes expedite the correct diagnosis and treatment.

    Intracerebellar hemorrhage is very rare in term infants and only severe cases with massive intracranial hemorrhage, posthemorrhagic hydrocephalus and clinical deterioration due to increased intracranial pressure require neurosurgical evacuation. In recent adult studies endoscopic hematoma evacuation has been shown as a rapid, effective, and safe technique. A term newborn hospitalized for meconium aspiration syndrome showed hypertonia, jitteriness and abnormal amplitude integrated electroencephalogram findings. He was diagnosed with cerebellar hematoma which caused hydrocephalus by cranial magnetic resonance imaging (MRI). The hematoma was successfully evacuated neuroendoscopically as the first case in literature to our knowledge. Neurologic, a-EEG and MRI findings resolved.

    2015-01-01

    Full Text Available The paper describes subarachnoid hemorrhage (SAH and hematomyelia resulting from bleeding from spinal hemangioblastoma. SAH is encountered in spinal pathology extremely rarely and results from bleeding from malformations in most cases. The described case demonstrates that the tumors may also cause spinal SAH even there is no clinical evidence of gradually progressive spinal cord compression in the history. Patients with hemangioblastoma are at the highest risk for clinically relevant massive bleeding in intramedullary tumors. In this case, of special attention is its clinical picture: SAH began with neck and arm pain, rather than headache, which indicates the primarily spinal level of bleeding. Head and arm pains were joined by SAH -typical headache, nausea, and vomiting in only a few minutes, which was associated with retrograde blood flow into the basal cisterns of the brain and the fourth ventricle. Primary MRI of the cervical spine was a more rational diagnostic scheme in this case.

    Full Text Available OBJECTIVE: To define the anatomy of dentate nucleus and cerebellar peduncles, demonstrating the surgical application of anatomic landmarks in cerebellar resections. METHODS: Twenty cerebellar hemispheres were studied. RESULTS: The majority of dentate nucleus and cerebellar peduncles had demonstrated constant relationship to other cerebellar structures, which provided landmarks for surgical approaching. The lateral border is separated from the midline by 19.5 mm in both hemispheres. The posterior border of the cortex is separated 23.3 mm from the posterior segment of the dentate nucleus; the lateral one is separated 26 mm from the lateral border of the nucleus; and the posterior segment of the dentate nucleus is separated 25.4 mm from the posterolateral angle formed by the junction of lateral and posterior borders of cerebellar hemisphere. CONCLUSIONS: Microsurgical anatomy has provided important landmarks that could be applied to cerebellar surgical resections.

    BACKGROUND: At present, it is satisfactory for micro-trauma craniopuncture therapy for cerebral hemor rhage to treat spontaneous intracerebral hemorrhage (ICH). Surgical treatment can decrease fatality rate of ICH patients; however, some reports suggest that there are no obvious differences of therapeutic effects between surgical treatment and medical therapy because of various states, operative indications, contraindi cations and operative styles.OBJECTIVE: To observe the effect of surgical treatment on ICH prognosis, especially on fatality rate. DESIGN: Retrospective-case study.SETTING: Huaibei People's Hospital. PARTICIPANTS: ① A total of 241 ICH patients selected from Huaibei People's Hospital from January 1988 to May 1989 were regarded as group A. They were all coincidence with Diagnostic Criteria of Intracerebral Hemorrhage in the National Cerebrovascular Disease Academic Meeting. There were 154 males and 87 females aged 34-94 years, and among them, 230 patients were older than 50 years (95.4%). Hemorrhage sites: Among 142 patients, 85 cases had internal capsule hemorrhage, 18 external capsule hemorrhage, 15 thalamic hemorrhage, 9 cerebellar hemorrhage, 7 brain stem hemorrhage, 7 cerebral lobe hemorrhage, and 1 corpus callosum hemorrhage. Hemorrhage volume: Among 89 clear records, 44 cases had of 1-10 mL, 35 of 11-30 mL, 5 of 31-40 mL, and 5 of 41-80 mL. Except 2 patients, other ones were treated with medical operation. ② A total of 203 ICH patients selected from the same hospital from January 2003 to December 2005 were regarded as group B. Among them, 72 cases were treated with operation, but other 131 ones were treated with non-operation. They were all diagnosed with CT. There were 113 males and 90 females aged 30-88 years, and among them, 183 patients were older than 50 years (90.1%). Hemorrhage sites: Among 203 patients, 104 cases had internal capsule hemorrhage, 17 external capsule hemorrhage, 19 thalamic hemorrhage, 9 cerebellar hemorrhage, 12 brain

    2015-04-01

    Alveolar hemorrhage occurs relatively rarely and is a therapeutic emergency because it can quickly lead to acute respiratory failure, which can be fatal. Hemoptysis associated with anemia and pulmonary infiltrates suggest the diagnosis of alveolar hemorrhage, but may be absent in one third of cases including patients in respiratory distress. The diagnosis of alveolar hemorrhage is based on the findings of a bronchoalveolar lavage. The causes are numerous. It is important to identify alveolar hemorrhage due to sepsis, then separate an autoimmune cause (vasculitis associated with antineutrophil cytoplasmic antibody, connective tissue disease and Goodpasture's syndrome) with the search for autoantibodies and biopsies from readily accessible organs, from a non-immune cause, performing echocardiography. Lung biopsy should be necessary only in exceptional cases. If the hemorrhage has an immune cause, treatment with steroids and cyclophosphamide may be started. The indications for treatment with rituximab are beginning to be established (forms that are not severe and refractory forms). The benefit of plasma exchange is unquestionable in Goodpasture's syndrome. In patients with an immune disease that can lead to an alveolar hemorrhage, removing any source of infection is the first priority.

    cerebral hemorrhage complicated with stress ulcer (SU). Methods The clinical data of 1 185 patients with cerebral hemorrhage admitted to Department of Emergency Medicine of Nanjing General Hospital from March 2006 to March 2014 were retrospectively analyzed. Patients were divided into two groups according to whether patients complicated with SU or not. Data was collected within 8 hours after admission in two groups including gender,age,amount of bleeding,the bleeding site (basal ganglia,thalamus, brainstem,brain lobe,ventricle,subarachnoid,and cerebellum),disturbance of consciousness,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,systolic blood pressure(SBP),history of hypertension,and history of cerebral hemorrhage. The statistically significant risk factors found using univariate analysis was selected and was analyzed to find independent risk factors with multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve)was plotted to analyze the independent risk factors and evaluate their power of test. Results 1 185 patients with cerebral hemorrhage were enrolled in the study,293 cases occurred SU,accounting for 24.7%,and 892 cases without SU,which accounted for 75.3%. As shown by univariate analysis,risk factors for cerebral hemorrhage complicated with SU included age,amount of bleeding,the bleeding site,disturbance of consciousness,APACHEⅡscore,SBP. As to the site of bleeding,brain,thalamus,brainstem hemorrhage complicated with SU were higher proportion,45.3%(43/95),39.1%(63/161),36.9%(48/130),which were significantly higher than those of the lobes of the brain 〔26.2% (33/126)〕,cerebellum 〔18.8% (15/80)〕,basal ganglia〔16.1%(78/485)〕,arachnoid the inferior vena cava 〔12.0% (13/108)〕.

    2009-06-01

    Cerebellar haemorrhages are rare life-threatening complications following spine surgery that present challenges for their diagnostic and their therapeutic management. Their patho-physiology remains unclear.We report a case of a life-threatening cerebellar haemorrhage secondary to an occult dural tear following a planned L5-S1 laminectomy. The patient was treated with emergent external ventriculostomy following by a posterior fossa decompressive craniectomy. Cerebellar haemorrhages have to be suspected systematically when unexpected neurological signs occur after spine surgery since their rapid management lead to favourable outcomes. The present imaging findings allow us proposing that cerebellar haemorrhages result primarily from superior cerebellar venous stretching and tearing, and that cerebellar infarction and swelling occur secondarily.

    An 11-week-old, male, Staffordshire Bull Terrier had a history of generalized ataxia and falling since birth. The neurologic findings suggested a localization in the cerebellum. Magnetic resonance imaging of the brain was performed. In all sequences the area of the cerebellum was almost replaced by fluid isointense to cerebrospinal fluid. A complete necropsy was performed after euthanasia. Histologically, the lesion was characterized by extensive loss of cerebellar tissue in both hemispheres and vermis. Toward the surface of the cerebellar defect, the cavity was confined by ruptured and folded membranes consisting of a layer of glial fibrillary acidic (GFAP)-positive glial cells covered multifocally by epithelial cells. Some of these cells bore apical cilia and were cytokeratin and GFAP negative, supporting their ependymal origin. The histopathologic features of our case are consistent with the diagnosis of an ependymal cyst. Its glial and ependymal nature as demonstrated by histopathologic and immunohistochemical examination differs from arachnoid cysts, which have also been reported in dogs. The origin of these cysts remains controversial, but it has been suggested that they develop during embryogenesis subsequent to sequestration of developing neuroectoderm. We speculate that the cyst could have been the result of a pre- or perinatal, possibly traumatic, insult because hemorrhage, and tissue destruction had occurred. To our knowledge, this is the first description of an ependymal cyst in the veterinary literature.

    Intracranial aneurysms in the pediatric population are rare. We report a case of a 3-month-old infant who presented with inconsolable crying, vomiting, and sunset eye sign. CT revealed a subarachnoid hemorrhage, with CT angiogram revealing a superior cerebellar artery aneurysm. An external ventricular drain was placed for acute management of hydrocephalus, with definitive treatment by endovascular technique with a total of six microcoils to embolize the aneurysm. Serial transcranial Dopplers revealed no subsequent vasospasm. Although aneurysms in the pediatric population are rare, once the diagnosis is established, early treatment results in better outcomes.

    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 Cerebellar ataxias comprise a wide range of etiologies leading to central nervous system-related motor and non-motor symptoms. Recently, a large body of evidence has demonstrated a high frequency of non-motor manifestations in cerebellar ataxias, specially in autosomal dominant spinocerebellar ataxias (SCA. Among these non-motor dysfunctions, sleep disorders have been recognized, although still under or even misdiagnosed. In this review, we highlight the main sleep disorders related to cerebellar ataxias focusing on REM sleep behavior disorder (RBD, restless legs syndrome (RLS, periodic limb movement in sleep (PLMS, excessive daytime sleepiness (EDS, insomnia and sleep apnea.

    Objective To compare the clinical evolution of perimesencephalic subarachnoid hemorrhage and non-perimesencephalic subarachnoid hemorrhage. Methods The study was conducted retrospectively in a tertiary hospital center in the north region of Portugal. Included patients had no identifiable cause for subarachnoid hemorrhage. Several epidemiologic, clinical and imaging aspects were statistically analyzed, taking into account the differences in perimesencephalic subarachnoid hemorrhage and non-perimesencephalic subarachnoid hemorrhage. Results Sixty-two patients met the inclusion criteria (46.8% - perimesencephalic subarachnoid hemorrhage; 53.2% - non-perimesencephalic subarachnoid hemorrhage). Demographic and clinical background characteristics were similar in both groups. Complications were more frequent in patients with non-perimesencephalic subarachnoid hemorrhage - 84.8% of the patients had at least one complication versus 48.3% in perimesencephalic subarachnoid hemorrhage. Vasospasm, infection and hydrocephaly were the most common complications (each was detected more frequently in the non-perimesencephalic subarachnoid hemorrhage group than in perimesencephalic subarachnoid hemorrhage group). Two patients died, both had a non-perimesencephalic subarachnoid hemorrhage. The median inpatient time was longer in the non-perimesencephalic subarachnoid hemorrhage group (21 versus 14 days). No incidents of rebleeding were reported during the follow-up period (mean time of 15 ± 10.3 months). Conclusion Perimesencephalic subarachnoid hemorrhage and non-perimesencephalic subarachnoid hemorrhage are two different entities that have different clinical outcomes, namely in terms of complication rate and median inpatient time. The management of these patients should respect this difference to improve treatment and optimize health care resources. PMID:27410409

    1987-07-01

    We used positron emission tomography (PET) with (/sup 18/F)2-deoxyglucose to study cerebellar glucose metabolism (LCMRglu) and the effect of phenytoin (PHT) in 42 patients with complex partial seizures (CPS), and 12 normal controls. Mean +/- SD patient LCMRglu was 6.9 +/- 1.8 mg glucose/100 g/min (left = right), significantly lower than control values of 8.5 +/- 1.8 (left, p less than 0.006), and 8.3 +/- 1.6 (right, p less than 0.02). Only four patients had cerebellar atrophy on CT/MRI; cerebellar LCMRglu in these was 5.5 +/- 1.5 (p = 0.054 vs. total patient sample). Patients with unilateral temporal hypometabolism or EEG foci did not have lateralized cerebellar hypometabolism. Patients receiving phenytoin (PHT) at the time of scan and patients with less than 5 years total PHT exposure had lower LCMRglu, but the differences were not significant. There were weak inverse correlations between PHT level and cerebellar LCMRglu in patients receiving PHT (r = -0.36; 0.05 less than p less than 0.1), as well as between length of illness and LCMRglu (r = -0.22; 0.05 less than p less than 0.1). Patients with complex partial seizures have cerebellar hypometabolism that is bilateral and due only in part to the effect of PHT.

  1. Characteristics of Hemorrhagic Stroke following Spine and Joint Surgeries

    Science.gov (United States)

    2017-01-01

    Hemorrhagic stroke can occur after spine and joint surgeries such as laminectomy, lumbar spinal fusion, tumor resection, and total joint arthroplasty. Although this kind of stroke rarely happens, it may cause severe consequences and high mortality rates. Typical clinical symptoms of hemorrhagic stroke after spine and joint surgeries include headache, vomiting, consciousness disturbance, and mental disorders. It can happen several hours after surgeries. Most bleeding sites are located in cerebellar hemisphere and temporal lobe. A cerebrospinal fluid (CSF) leakage caused by surgeries may be the key to intracranial hemorrhages happening. Early diagnosis and treatments are very important for patients to prevent the further progression of intracranial hemorrhages. Several patients need a hematoma evacuation and their prognosis is not optimistic. PMID:28164124

    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.

    A case of cerebral hemorrhage associated with sildenafil (Revatio) use in an infant is presented. Sildenafil is increasingly used in the treatment of primary and secondary pulmonary arterial hypertension and pulmonary arteriovenous fistula. In the reported case, sildenafil used to treat pulmonary arteriovenous fistula improved right-to-left shunting across the pulmonary fistula but resulted in cerebral hemorrhage. Cerebral hemorrhage, a previously reported complication of sildenafil, developed in an infant after a rapid increase in dose, to 4.7 mg/kg/day. Therefore, sildenafil doses must be increased only with care, and cerebral hemorrhage must be considered a potential complication.

    Uremic encephalopathy (UE) is a well-known complication of uremia, but its pathophysiology remains unknown. It is widely reported that in UE, the bilateral basal ganglia (BG) shows hyperintensities on T2/fluid attenuated inversion recovery magnetic resonance imaging (MRI), but cerebellar lesions are extremely rare, with to the best of our knowledge, only one case reported to date. We describe the findings from computed tomography and MRI for typical BG and cerebellar vermis lesions.

    Adrenal hemorrhage (AH) is a well-described complication of the neonatal period, anticoagulant therapy, and overwhelming bacterial infection especially with N. meningitis. Until recently the diagnosis of acute AH was based predominantly on autopsy findings. Ultrasound and computed tomography examinations have been successfully used for antemortem detection of AH in neonates and anticoagulated patients. We report two patients with fulminant meningococcal infection who demonstrated bilateral adrenal hemorrhages on ultrasonography.

    We report a 50-year-old woman with a chondromyxoid fibroma of the occipital bone, who presented with a cerebellar hemorrhage due to invasion of the adjacent sinus. Chondromyxoid fibromas are benign cartilaginous tumors. However, this case represents the first example, to our knowledge, of a chondromyxoid fibroma invading the transverse-sigmoid junction, resulting in intracranial hemorrhage. Our report highlights that the location of an intracranial chondromyxoid fibroma is an important factor in guiding surgical management.

    Nutritional cerebellar degeneration occurs in alcoholism and other states that predispose to malnutrition, such as gastric bypass surgery. Gait ataxia is the principal clinical manifestation. Ataxia of the lower limbs is not uncommon, but upper extremity ataxia and nystagmus are rare. Atrophy of the anterior superior vermis is the primary pathological manifestation in established disease. Typically, the onset is subacute. This cerebellar disease is part of the spectrum of the Wernicke-Korsakoff syndrome, i.e. the cerebellar manifestation of Wernicke disease. It may occur with other lesions of Wernicke disease or in isolation. Rarely, with florid disease, lesions may be hemorrhagic. Active disease should be treated with thiamine in the same way that one treats Wernicke disease. Clinicopathologic correlation in this disease has provided the best evidence that the anterior superior vermis is important in coordinating bipedal locomotion.

    Full Text Available Cerebral edema resulting in elevated intracranial pressure is a well-known complication of galactosemia. Lumbar puncture was performed for the diagnosis of clinically suspected bacterial meningitis. Herniation of cerebral tissue through the foramen magnum is not a common problem in neonatal intensive care units because of the open fontanelle in infants. We present the case of a 3-week-old infant with galactosemia who presented with signs of cerebellar herniation after lumbar puncture.

    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.

    BACKGROUND: Presently, there have been craniocerebral operation, interventional embolization,stereotactic radiotherapy and other methods in treating cerebral arteriovenous malformation (AVM).However, the standard of different therapeutic regimens of cerebral AVM at the acute stage of hemorrhage has not been completely identified.OBJECTIVE: To observe the clinical characteristics and therapeutic effects of AVM at the acute stage of hemorrhage in patients, and to analyze corresponding therapeutic strategies.DESIGN: Non-randomized clinical observation.SETTING: Department of Neurosurgery, Foshan First People's Hospital, Sun Yat-sen University.PARTICIPANTS: Forty-six patients with cerebral AVM complicated by hemorrhage admitted to Department of Neurosurgery, Foshan First People's Hospital between January 1999 and December 2006,were involved in this study. All the patients were confirmed as cerebral AVM complicated by hemorrhage by brain angiography or/and postoperational pathology. The involved patients, 32 males and 14 females,averaged 25 years old, ranging from 6 to 62 years. Informed consents of therapeutic items were obtained from the relatives of all the patients.METHODS: ①On admission, skull CT and brain angiography were conducted in the involved subjects. ②The therapeutic method was confirmed according to the consciousness, hematoma region, hematoma volume,imageological results following comprehensive analysis: DSA examination was permitted to identify the size and position of abnormal vessel mass, and the distribution of feeding artery and draining vein. Craniocerebral operation was carried out as early as possible in patients with severe or progressive conscious disturbance, in which most of hematoma with obvious occupied effect or cerebral hernia was located in lobe of brain. The primary thing was to clean intracerebral hematoma for in time decompression. According to different situations, corresponding therapeutic measures were used for resecting abnormal

    Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18-89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications. (orig.)

    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.

    Of all types of intracranial hemorrhage (ICH) in the neonates, germinal matrix intraventricular hemorrhage(GM-IVH) in the premature infant is the most common type, mainly attributed to the existence of immature germinal matrix, lt's usually lack of visible and specific symptoms and signs in the nervous system, so its early and final diagnosis depends on the imaging examine. GM-IVH can cause periventricular hemorrhagic infarction, post-hemorrhagic hydrocephalus, periventricular leukomalacia and the associated cerebellar hemorrhagic injury, which are critical determinants of neonatal morbidity, mortality, and neurodevelopmental outcome in the survivors. The overall aim of this article is to review the current knowledge of the cause,mechanisms, imaging diagnosis, complication, management and outcome of GM-IVH in the preterm infant.%早产儿生发基质-脑室内出血(GM-IVH)是新生儿颅内出血最常见的类型,主要与早产儿存在胚胎生发层基质有关,临床上往往缺乏明显或特异的神经系统症状和体征,其早期诊断和确诊有赖于影像学检查.GM-IVH可引起脑室周围出血性梗死、出血后脑积水、脑白质软化、小脑出血性损伤等并发症,是导致新生儿死亡和存活者预后不良的主要原因.该文主要综述早产儿GM-IVH的病因、发病情况、影像学诊断、并发症及其治疗与预后的最新研究进展.

    2006-12-01

    The complications of blepharoplasty are infrequent, most often minor and transient, and rarely major and permanent with functional or aesthetic consequences. Treatment is above all preventive with screening of "at risk" patients in whom blepharoplasty would be contra-indicated. Patients must be informed of possible risks through informative booklets stressing the most important points. The complications may affect vision. Partial or complete visual loss due to ischemic optic neuropathy, or rarely to compression of the ocular globe by intraorbital hemorrhage, is the most serious complication. Other visual complications include oculomotor disorders, keratoconjunctivitis sicca, epiphora, and chemosis of lymphatic origin. Eyelid complications are more frequent: ptosis of the upper eyelid or lagophthalmia caused by incorrect resection of the skin, scarring, and eyelid fold anomalies. The most severe aesthetic complication is the malposition of the lower eyelid resulting in retraction, lagophthalmia, ectropion, deformation of the external canthus, or lower eyelid tissue relaxation. These malpositions are often minor, sometimes reversible, but they can be major, with psychological, aesthetic, and functional consequences. Other local complications include enophthalmia and hypo- or hypercorrection. General complications may include pigmentation anomalies or infections extending as far as the orbital fat tissue. Finally, complications observed after the newer procedures of laser surgery include ectropion, burns and residual redness. Complications related to periocular injections of filling material are also mentioned. The discussion of these complications is followed by a comprehensive review of the prevention, diagnosis and management of the complications after blepharoplasty.

    2012-09-01

    Hemorrhage represents the most feared complication of cerebral arteriovenous malformations (AVMs) in both untreated patients and those treated with gamma knife radiosurgery. Radiosurgery does not immediately lead to obliteration of the malformation, which often does not occur until years following treatment. Post-obliteration hemorrhage is rare, occurring months to years after radiosurgery, and has been associated with residual or recurrent AVM despite prior apparent nidus elimination. Three cases are reported of delayed intracranial hemorrhage in patients with cerebral AVMs treated with radiosurgery in which no residual AVM was found on catheter angiography at the time of delayed post-treatment hemorrhage. That the pathophysiology of these hemorrhages involves progressive venous outflow occlusion is speculated and the possible mechanistic link to subsequent vascular rupture is discussed.

    2015-01-01

    Abstract The ventriculoperitoneal (VP) shunt is a routine procedure for cerebrospinal fluid (CSF) diversion, and is associated with many complications. A delayed hemorrhage after the VP shunt surgery, however, is quite rare. In this study, we report a case involving late-onset hemorrhage. The 67-year-old male patient with a history of head trauma and brain surgery underwent a VP shunt placement for hydrocephalus. The surgery course was uneventful and no bleeding was revealed in the first computed tomographic (CT) scan after the procedure. However, a massive intraparenchymal and intraventricular hemorrhage occurred 8 h following adjustment of the valve system on the 8th day after surgery. Erosion of the vasculature by catheter cannulation and a sudden reduction of CSF pressure after downregulation of the valve could be one of the possible causes of the intracerebral hemorrhage (ICH).

    We review the presentation, imaging findings and outcome in 18 children with cerebellar arteriovenous malformations (AVM). This group is of particular interest because of the reported poor outcome despite modern imaging and neurosurgical techniques. All children had CT and 15 underwent catheter angiography at presentation. Several of the children in the latter part of the study had MRI. Of the 18 children, 17 presented with a ruptured AVM producing intracranial haemorrhage. The remaining child presented with temporal lobe epilepsy and was shown to have temporal, vermian and cerebellar hemisphere AVM. This child had other stigmata of Osler-Weber-Rendu syndrome. Three other children had pre-existing abnormalities of possible relevance. One had a vascular malformation of the cheek and mandible, one a documented chromosomal abnormality and another a midline cleft upper lip and palate. Six of the 17 children with a ruptured cerebellar AVM died within 7 days of the ictus. Vascular pathology other than an AVM was found in 10 of the 14 children with a ruptured cerebellar AVM who had angiography: 4 intranidal aneurysms, 5 venous aneurysms and 2 cases of venous outflow obstruction (one child having both an aneurysm and obstruction). The severity of clinical presentation was directly related to the size of the acute haematoma, which was a reasonable predictor of outcome. (orig.) With 4 figs., 4 tabs., 23 refs.

    Nontraumatic (or spontaneous) intracranial hemorrhage most commonly involves the brain parenchyma and subarachnoid space. This entity accounts for at least 10% of strokes and is a leading cause of death and disability in adults. Important causes of spontaneous intracranial hemorrhage include hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformations, and hemorrhagic infarcts (both venous and arterial). Imaging findings in common and less common causes of spontaneous intracranial hemorrhage are reviewed.

    Full Text Available Chronic complications of acute appendicitis managed in a conservative manner are not frequent. We present a case of acute lower gastrointestinal hemorrhage in a young patient with a previous acute appendicitis without surgical intervention. The colonoscopy detected an appendicular bleeding which was surgically treated. The anatomopathological diagnosis was granulomatous appendicitis. The clinical evolution of the patient was favorable without bleeding recurrence. Appendicular hemorrhage can be an unusual complication -however potentially severe- of acute appendicitis not treated surgically.

    Secondary FAE is a rare complication, usually located at the duodenum. The typical clinical presentation is like a digestive hemorrhage or a sepsis. We report two cases of FAE with atypical manifestations. The first case presented a lower digestive hemorrhage produced by the fistulization to the sigma. The second case appeared like an intestinal obliteration caused by the full emigration of a prosthesis to the jejunum. We wish to remark the importance of the clinical suspicion of a FAE (Key of diagnosis), and the sparing relevance of the complementary examinations and the urgency of a surgical treatment in order to avoid the high rate of morbi-mortality associated with this complication.

    2012-02-01

    Hemorrhage remains as one of the top 3 obstetrics related causes of maternal mortality, with most deaths occurring within 24-48 hours of delivery. Although hemorrhage related maternal mortality has declined globally, it continues to be a vexing problem. More specifically, the developing world continue to shoulder a disproportionate share of hemorrhage related deaths (99%) compared with industrialized nations (1%). Given the often preventable nature of death from hemorrhage, the cornerstone of effective mortality reduction involves risk factor identification, quick diagnosis, and timely management. In this monograph we will review the epidemiology, etiology, and preventative measures related to maternal mortality from hemorrhage.

    A 7-month-old baby presented with a 4-day history of drowsiness and vomiting after a falling accident. Magnetic resonance imaging demonstrated diffuse subarachnoid hemorrhage, intraventricular hemorrhage, and variable stages of subdural hematoma in bilateral occipital and left temporal subdural spaces. A partially thrombosed aneurysm was noted in the right craniocervical junction. Ophthalmological examination revealed bilateral retinal petechial hemorrhages. Conventional cerebral angiography revealed a dissecting aneurysm in the right posterior inferior cerebellar artery (PICA). Endovascular embolization was suggested, but the family refused. After conservative treatment, follow-up MRI revealed that the PICA aneurysm had remodeled and ultimately disappeared completely at the 10th month. This case illustrates the relatively plastic nature of intracranial aneurysms in pediatric patients. More studies are necessary to clarify the natural history of spontaneously thrombosed aneurysms to assist in their overall management.

    The authors discuss eight cases who suffered hemorrhaging stress ulcers out of 200 cases on whom Thoracotomies were performed. Presented is the common factor of the onset of this complication, it's diagnosis, and therapy. Listed below are the diagnoses and operative procedures used on these eight patients. Cysta Aerea Permagna Lobi Inf. Pulm. Dexter/operation: Mytomis Longitudinalis Ooesophagi. Caverna Bronchiectatica Permagna Lobi Inferior Pulmo Dexter/operation: Lobestomia Typica.

Carcinoma Bronchi Lobi Inferior Pulmo Dexter/operation: Lobectomia Typica. Gastric problems had troubled four of these eight patients in their past history. Bleeding in three patients occurred three days postoperatively, and in the remaining five, thirty days following their operation. Six patients had to be treated conservatively because of serious contraindications to reoperation. Four of them expired. Autopsy revealed: Pyothorax, Dehiscention Bronchi, Empyema, and Gastritis Errosiva with multiulcerations, hemoragia, and dilatation of the right heart. Two patients with recent stress ulcers were reoperated on, and were cured. The authors estimate that the occurrence of hemorrhaging stress ulcer following thoracic surgery are basically due to Hypoxia. The chain of events whic brought about the stress ulcer, however, began even before the operation, continued throughout the operation, and appeared postoperatively due to postoperative complications. The authors point out that these complications can be foreseen (early and late), but firstly, an attempt should be made to treat the patient with conservative therapy. Inasmuch as the hemorrhaging

    The mortality for pancreatectomy has decreased to a very low level in recent years but morbidity remains high. The most frequent post-operative complications of pancreaticoduodenectomy (PD) are delayed gastric emptying (DGE) in 20% and pancreatic fistula (PF) in 10-15%. DGE is associated with other abdominal complications in half the cases; these must be delineated by CT scan and specifically treated. Isolated DGE usually resolves within three weeks with the use of nasogastric suction and pro-kinetic drugs. FP following PD may be preventable with the use of temporary trans-jejunal intubation of Wirsung's duct or by intussusception of the pancreatic margin into the jejunal lumen. FP occurring after PD will heal with conservative management (total parenteral nutrition, peripancreatic drainage, somatostatin analogues) in 80-90% of cases but secondary complications such as peritonitis, arterial erosion and pseudo-aneurysm may be life-threatening. Early hemorrhage (in the first 48-72 hours) must be treated by re-operation. Late hemorrhage (usually secondary to PF) and ischemic complications are rare (3% and 1% respectively), difficult to treat, and associated with high mortality. PF is also the main complication of distal pancreatectomy and enucleation of pancreatic tumors (10-20% and 30% respectively). These PF resolve with conservative treatment in more than 95% of cases but may justify an ERCP sphincterotomy if drainage is prolonged. After medial pancreatectomy, PF occurs in 20-30% of cases, arising from either of the two transected pancreatic surfaces.

    Complications of shoulder dystocia are divided into fetal and maternal. Fetal brachial plexus injury (BPI) is the most common fetal complication occurring in 4-40% of cases. BPI has also been reported in abdominal deliveries and in deliveries not complicated by shoulder dystocia. Fractures of the fetal humerus and clavicle occur in about 10.6% of cases of shoulder dystocia and usually heal with no sequel. Hypoxic ischemic brain injury is reported in 0.5-23% of cases of shoulder dystocia. The risk correlates with the duration of head-to-body delivery and is especially increased when the duration is >5 min. Fetal death is rare and is reported in 0.4% of cases. Maternal complications of shoulder dystocia include post-partum hemorrhage, vaginal lacerations, anal tears, and uterine rupture. The psychological stress impact of shoulder dystocia is under-recognized and deserves counseling prior to home discharge.

    Multimodality therapies that include surgery, chemotherapy, radiotherapy, and various newer forms of targeted therapies have been commonly applied in childhood cancers. Such modalities are associated with complications that may adversely affect the outcome of cancer treatment. Acute complications that require surgical management form the focus of our discussion. These patients are often compromised by immunosuppression, thrombocytopenia, and malnutrition. The complications discussed include typhlitis, invasive aspergillosis (IA), pancreatitis, hemorrhagic cystitis, gastrointestinal hemorrhage, necrotizing skin and soft-tissue infections, and perianal infection. Familiarity with the spectrum of complications and their appropriate management approaches will minimize the patients' morbidity.

    Directory of Open Access Journals (Sweden)

    Salvador eMartinez

    2013-06-01

    Full Text Available Historically, the molecular and cellular mechanisms of cerebellar development were investigated through structural descriptions and studying spontaneous mutations in animal models and humans. Advances in experimental embryology, genetic engineering and neuroimaging techniques render today the possibility to approach the analysis of molecular mechanisms underlying histogenesis and morphogenesis of the cerebellum by experimental designs. Several genes and molecules were identified to be involved in the cerebellar plate regionalization, specification and differentiation of cerebellar neurons, as well as the establishment of cellular migratory routes and the subsequent neuronal connectivity. Indeed, pattern formation of the cerebellum requires the adequate orchestration of both key morphogenetic signals, arising from distinct brain regions, and local expression of specific transcription factors. Thus, the present review wants to revisit and discuss these morphogenetic and molecular mechanisms taking place during cerebellar development in order to understand causal processes regulating cerebellar cytoarchitecture, its highly topographically ordered circuitry and its role in brain function.

    Rarely, a solitary posterior inferior cerebellar artery (PICA) will supply both cerebellar hemispheres. We report four cases of this variant. We present a retrospective review of clinical information and imaging of patients undergoing angiography at our institution to identify patients with a bihemispheric PICA. There were four patients: three males and one female. One patient presented with a ruptured arteriovenous malformation, and one with a ruptured aneurysm. Two patients had normal angiograms. The bihemispheric PICA was an incidental finding in all cases. The bihemispheric vessel arose from the dominant left vertebral artery, and the contralateral posterior inferior cerebellar artery was absent or hypoplastic. In all cases, contralateral cerebellar supply arose from a continuation of the ipsilateral PICA distal to the choroidal point and which crossed the midline dorsal to the vermis. We conclude that the PICA may supply both cerebellar hemispheres. This rare anatomic variant should be considered when evaluating patients with posterior fossa neurovascular disease. (orig.)

    It has been proposed that the biological basis of autism spectrum disorder includes cerebellar 'disconnection'. However, direct in vivo evidence in support of this is lacking. Here, the microstructural integrity of cerebellar white matter in adults with Asperger syndrome was studied using diffusion tensor magnetic resonance tractography. Fifteen adults with Asperger syndrome and 16 age-IQ-gender-matched healthy controls underwent diffusion tensor magnetic resonance imaging. For each subject, tract-specific measurements of mean diffusivity and fractional anisotropy were made within the inferior, middle, superior cerebellar peduncles and short intracerebellar fibres. No group differences were observed in mean diffusivity. However, people with Asperger syndrome had significantly lower fractional anisotropy in the short intracerebellar fibres (pAsperger syndrome. The localised abnormalities in the main cerebellar outflow pathway may prevent the cerebral cortex from receiving those cerebellar feedback inputs necessary for a successful adaptive social behaviour.

    Percutaneous interventional therapy plays an important role in treating complications of acute and chronic pancreatitis. With the development of cross-sectional imaging and advanced interventional techniques, percutaneous drainage has become the preferred treatment for pancreatic fluid collections such as acute collections, pseudocysts and abscesses. Abscess and pancreatic hemorrhage are the most life threatening complications of pancreatitis. Massive hemorrhage is rare but frequently lethal. As a rule, bleeding complications of pancreatitis require prompt diagnosis and an aggressive surgical approach. In unstable patients with a severely bleeding pseudoaneurysm, hemostasis can be obtained by occlusion with mechanical devices.

    Blepharoplasty complications are infrequent, most often minor and transitory, rarely major and permanent with functional or esthetic consequences. Treatment is above all preventive: screening at risk patients with a history of ophthalmic problems, but also general illnesses that would contraindicate blepharoplasty. Patients must be informed of possible risks through informative booklets with the most important points underlined. Complications can be purely ophthalmological, the more serious sequelae being partial or complete visual loss due to ischemic optical neuropathy, with very poor prognosis, or more rarely compression of the ocular globe by intraorbital hemorrhage, which has a better prognosis provided the origins are quickly recognized and treated immediately. Other visual complications include oculomotor problems, keratoconjunctivitis sicca, epiphora, and chemosis of lymphatic origin. Eyelid complications are more frequent: ptosis on the upper eyelid or lagophthalmia caused by incorrect resection of the skin, scarring and eyelid fold anomalies. The most serious esthetic complication is the malposition of the lower eyelid, which can manifest as retraction, lagophthalmia, ectropion, deformation of the external canthus, or lower eyelid tissue relaxation. These malpositions are quite often minor, sometimes reversible, but at times major, with psychological, esthetic and functional consequences that are difficult for the patient. Other local complications also arise: enophthalmia with a sunken lid, as well as under- and overcorrection. General complications can include scarring related to pigmentation problems and residual hematomas, and exceptionally infections going as far as the orbital fat tissue. Finally, other complications are related to new laser surgical techniques that are responsible for ectropion of the lower eyelid and even burns or residual redness, or complications related to periocular injections of filling material.

    Background Cerebral hemorrhage is common in patients with cancer, but the clinical features and pathogenesis of liver cancer patients with cerebral hemorrhage are not well known. Material/Methods Liver cancer patients who developed cerebral hemorrhage were recruited from the First Affiliated Hospital of Guangxi Medical University between January 2003 and December 2014. We retrospectively analyzed clinical presentations, results of laboratory tests, and imaging examinations. The clinical features and pathogenesis were summarized. Results Among 11133 patients with liver cancer, 9 patients (0.08%), including 3 females and 6 males met the inclusion criteria. The age range was 48–73 years and the average age was 61.67±8.97 years. Five patients did not have traditional hemorrhage risk factors and 4s had the risk factors; however, all had developed hepatocellular carcinoma, and 3 had developed metastasis. All 9 patients showed elevated tumor markers: an increased AFP level was detected in 6 patients, coagulation dysfunctions in 8 patients, and abnormal liver functions in 6 patients. Five patients had developed cerebral hemorrhagic lesions in the lobes of their brains, while hemorrhagic lesions in the basal ganglia occurred in 3 patients and in the brainstem in only 1 patient. Four patients had clear consciousness, while 5 patients were in coma and showed poor prognosis. Conclusions Patients who have liver cancer complicated with cerebral hemorrhage usually lack traditional risk factors of cerebral hemorrhage. The site of cerebral hemorrhage is often detected in the lobes of the brain. Coagulation dysfunctions might be the main pathogenesis of liver cancer complicated with cerebral hemorrhage.

    Varicella (chickenpox) is a common childhood infection caused by the varicella-zoster virus, which is often self-limiting and usually benign. Although uncommon, neurologic complications of varicella have been documented that include postinfectious cerebellar ataxia, meningoencephalitis, Reye syndrome, myelitis, optic neuritis, stroke, Guillain-Barré syndrome, seventh cranial nerve palsy, and Ramsay-Hunt syndrome. In this case study, the authors describe a 7-year-old girl who presented with varicella skin rash with unsteady gait and anarthria on day 2, and her condition was attributed to cerebellar mutism. To date, this complication has never been reported in a child with primary varicella infection. Therefore, this case study documents a rare but serious complication of childhood chickenpox.

A 4-year-old man hospitalized for sudden onset left hemiparesis and hypertension was diagnosed to have right thalamic and midbrain hemorrhage on plain CT scan of the head which also revealed co-existent extensive intracranial calcifications involving the basal ganglia and cerebellum bilaterally. General physical examination revealed features of Albright hereditary osteodystrophy, goitre, hypertension, left hemiparesis, and signs of cerebellar dysfunction. Laboratory findings suggested hypocalcemia, hyperphosphatemia along with high TSH, low FT4, low FT3, and high anti-TPO antibody. Though bilateral intracranial calcifications are usually encountered as an incidental radiological finding in the CT scan of brain, in this case, the patient admitted for thalamic and midbrain hemorrhage was on investigation for associated intracranial calcification, and goitre was also found to have coexisting pseudohypoparathyroidism and autoimmune hypothyroidism.

    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>1μg/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.

The mean interval between the two bleeding episodes was 44.6 ± 12.5 months. The 73.3%patients were hypertensive .′The site of the first hemorrhage was ganglionic in 8 patients , ]ohar in six paients and brainstem in one .The recurrent hemorrhage occurred at a different location from the previous ICH.The most common pattern of recurrence was “ganglionic -ganglionic” (7 patients), lobar - ganglionic (3 patients), lobar-lobar(three patients), which was always observed in hypertensive patients. The outcome after the recurrent hemorrhage was usually poor. By comparison with 24 patients followed up to average 47.5± 18.7 months with isolated ICH without recurrence .Only lobar hematoma and a younger age were risk factors for recurrences whereas sex and previous hypertension were not. The mechanism of recurrence of ICH were multiple(hypertension, cerebral amyloid angiopathy).Contral of blood pressure and good living habit after the first hemorrhage may prevent ICH recurrences.

  19. Synchrony and neural coding in cerebellar circuits

    Directory of Open Access Journals (Sweden)

    Abigail L Person

    2012-12-01

    Full Text Available The cerebellum regulates complex movements and is also implicated in cognitive tasks, and cerebellar dysfunction is consequently associated not only with movement disorders, but also with conditions like autism and dyslexia. How information is encoded by specific cerebellar firing patterns remains debated, however. A central question is how the cerebellar cortex transmits its integrated output to the cerebellar nuclei via GABAergic synapses from Purkinje neurons. Possible answers come from accumulating evidence that subsets of Purkinje cells synchronize their firing during behaviors that require the cerebellum. Consistent with models predicting that coherent activity of inhibitory networks has the capacity to dictate firing patterns of target neurons, recent experimental work supports the idea that inhibitory synchrony may regulate the response of cerebellar nuclear cells to Purkinje inputs, owing to the interplay between unusually fast inhibitory synaptic responses and high rates of intrinsic activity. Data from multiple laboratories lead to a working hypothesis that synchronous inhibitory input from Purkinje cells can set the timing and rate of action potentials produced by cerebellar nuclear cells, thereby relaying information out of the cerebellum. If so, then changing spatiotemporal patterns of Purkinje activity would allow different subsets of inhibitory neurons to control cerebellar output at different times. Here we explore the evidence for and against the idea that a synchrony code defines, at least in part, the input-output function between the cerebellar cortex and nuclei. We consider the literature on the existence of simple spike synchrony, convergence of Purkinje neurons onto nuclear neurons, and intrinsic properties of nuclear neurons that contribute to responses to inhibition. Finally, we discuss factors that may disrupt or modulate a synchrony code and describe the potential contributions of inhibitory synchrony to other motor

    Recent advances in MRI have revealed congenital brain malformations and subtle developmental abnormalities of the cerebral and cerebellar cortical architecture. Typical cerebellar cortical dysplasia as a newly categorized cerebellar malformation, has been seen in patients with Fukuyama congenital muscular dystrophy. Cerebellar cortical dysplasia occurs at the embryonic stage and is often observed in healthy newborns. It is also incidentally and initially detected in adults without symptoms. To the best of our knowledge, cerebellar dysplasia without any related disorders is very rare. We describe the MRI findings in one patient with disorganized foliation of both cerebellar hemispheres without a related disorder or syndrome

    Currently, 422 million adults suffer from diabetes worldwide, leading to tremendous disabilities and a great burden to families and society. Functional and structural MRIs have demonstrated that patients with type 2 diabetes mellitus (T2DM) exhibit abnormalities in brain regions in the cerebral cortex. However, the changes of cerebellar anatomical connections in diabetic patients remains unclear. In the current study, diffusion tensor imaging deterministic tractography and statistical analysis were employed to investigate abnormal cerebellar anatomical connections in diabetic patients. This is the first study to investigate the altered cerebellar anatomical connectivity in T2DM patients. Decreased anatomical connections were found in the cerebellar and cerebro-cerebellar circuits of T2DM patients, providing valuable new insights into the potential neuro-pathophysiology of diabetes-related motor and cognitive deficits.

    Paraneoplastic neurological disorders are rare complications of breast carcinoma. Lambert-Eaton Myasthenic Syndrome (LEMS) is most commonly associated with small cell lung cancer. However, a combination of LEMS and subacute cerebellar degeneration as paraneoplastic syndromes is extremely rare, and has never been described in association with breast cancer.

    The aims of this study were to identify arteriographic manifestations of acute renal hemorrhage and to evaluate the efficacy of emergency embolization. Emergency renal artery angiography was performed on 83 patients with acute renal hemorrhage. As soon as bleeding arteries were identified, emergency embolization was performed using gelatin sponge, polyvinyl alcohol particles, and coils. The arteriographic presentation and the effect of the treatment for acute renal hemorrhage were analyzed retrospectively. Contrast extravasation was observed in 41 patients. Renal arteriovenous fistulas were found in 12 of the 41 patients. In all, 8 other patients had a renal pseudoaneurysm, 5 had pseudoaneurysm rupture complicated by a renal arteriovenous fistula, and 1 had pseudoaneurysm rupture complicated by a renal artery-calyceal fistula. Another 16 patients had tumor vasculature seen on arteriography. Before the procedure, 35 patients underwent renal artery computed tomography angiography (CTA). Following emergency embolization, complete hemostasis was achieved in 80 patients, although persistent hematuria was present in 3 renal trauma patients and 1 patient who had undergone percutaneous nephrolithotomy (justifying surgical removal of the ipsilateral kidney in this patient). Two-year follow-up revealed an overall effective rate of 95.18 % (79/83) for emergency embolization. There were no serious complications. Emergency embolization is a safe, effective, minimally invasive treatment for renal hemorrhage. Because of the diversified arteriographic presentation of acute renal hemorrhage, proper selection of the embolic agent is a key to successful hemostasis. Preoperative renal CTA plays an important role in diagnosing and localizing the bleeding artery.

    Focal lesions of brainstem, thalamus, and subcortical white matter may cause movement disorders that are clinically indistinguishable from cerebellar symptoms. It is suspected that ataxia in these cases is due to damage of efferent or afferent pathways of the cerebellum. However, the precise anatomical correlate often remains undefined. We used deterministic diffusion tensor magnetic resonance imaging (DTI) tractography to study the anatomical relationship between lesions causing ataxia and efferent cerebellar pathways. Study subjects were six male patients with focal lesions of different etiology (demyelination, hemorrhage, ischemia, neoplasm) outside the cerebellum. Five patients had cerebellar-like ataxia with prominent contralateral upper limb involvement. One patient with an almost midline mesencephalic lesion had a symmetrical ataxic syndrome. We used 3T MRI (Intera, Philips Medical Systems, Best, Netherlands) and DTI tractography (32 directions, StealthViz DTI, Medtronic Navigation, Louisville, USA) to delineate the dentato-rubro-thalamo-cortical tract (DRT). In all patients, tractography demonstrated focal lesions affecting the DRT in different locations. We conclude that in vivo mapping of cerebral pathways using DTI tractography in patients with focal extracerebellar brain lesions may provide direct evidence of circumscribed damage to the DRT, causing unilateral cerebellar-like ataxia. Also, a unilateral mesencephalic lesion at the level of the crossing of the DRT may cause bilateral ataxia.

    Eleven patients with acquired cerebellar degeneration (10 of whom had paraneoplastic cerebellar degeneration (PCD)) were evaluated using neuropsychological tests and /sup 18/F-fluorodeoxyglucose/positron emission tomography to (1) quantify motor, cognitive, and metabolic abnormalities; (2) determine if characteristic alterations in the regional cerebral metabolic rate for glucose (rCMRGlc) are associated with PCD; and (3) correlate behavioral and metabolic measures of disease severity. Eighteen volunteer subjects served as normal controls. Although some PCD neuropsychological test scores were abnormal, these results could not, in general, be dissociated from the effects of dysarthria and ataxia. rCMRGlc was reduced in patients with PCD (versus normal control subjects) in all regions except the brainstem. Analysis of patient and control rCMRGlc data using a mathematical model of regional metabolic interactions revealed two metabolic pattern descriptors, SSF1 and SSF2, which distinguished patients with PCD from normal control subjects; SSF2, which described a metabolic coupling between cerebellum, cuneus, and posterior temporal, lateral frontal, and paracentral cortex, correlated with quantitative indices of cerebellar dysfunction. Our inability to document substantial intellectual impairment in 7 of 10 patients with PCD contrasts with the 50% incidence of dementia in PCD reported by previous investigators. Widespread reductions in PCD rCMRGlc may result from the loss of cerebellar efferents to thalamus and forebrain structures, a reverse cerebellar diaschisis.

    Cerebellar dysfunction can lead to a wide range of movement disorders. Studying the cerebellar atrophy pattern associated with different cerebellar disease types can potentially help in diagnosis, prognosis, and treatment planning. In this paper, we present a landmark based shape analysis pipeline to classify healthy control and different ataxia types and to visualize the characteristic cerebellar atrophy patterns associated with different types. A highly informative feature representation of the cerebellar structure is constructed by extracting dense homologous landmarks on the boundary surfaces of cerebellar sub-structures. A diagnosis group classifier based on this representation is built using partial least square dimension reduction and regularized linear discriminant analysis. The characteristic atrophy pattern for an ataxia type is visualized by sampling along the discriminant direction between healthy controls and the ataxia type. Experimental results show that the proposed method can successfully classify healthy controls and different ataxia types. The visualized cerebellar atrophy patterns were consistent with the regional volume decreases observed in previous studies, but the proposed method provides intuitive and detailed understanding about changes of overall size and shape of the cerebellum, as well as that of individual lobules.

    Cerebellar mass lesion is an uncommon presentation of toxoplasmosis. The authors report one rare case in an 11-month-old HIV/AIDS female infant who presented with deterioration in her developmental milestones. CT scan revealed a ring-enhancing mass lesion in the right cerebellar hemisphere with secondary obstructive hydrocephalus. A ventriculoperitoneal shunt was inserted prior to posterior fossa decompression and biopsy of the lesion. The specimens obtained were divided into two. One specimen was sent for histological diagnosis immediately after surgery while the second specimen was preserved until the release of the histology report. The initial histopathology report indicated a neoplastic process. Immunohistochemical stains were attempted but interpreted with difficulty due to severe tissue necrosis. After waiting for close to 6 weeks without a definite histological diagnosis, the preserved second specimen was sent for histological analysis as a fresh specimen, and reported a diagnosis of toxoplasmosis. This case presented diagnostic challenges to the authors whose radiological impressions of either a neoplastic lesion or a tuberculoma (based on our local neuroepidemiology) were reinforced by intraoperative findings highly suggestive of tuberculoma but which contrasted with the histological report, first as a neoplastic lesion and later toxoplasmosis. Although cerebellar toxoplasmosis is a rare complication of HIV/AIDS, this case report shows that toxoplasmosis should not be overlooked as a differential diagnosis of ring-enhancing cerebellar masses in HIV/AIDS patients irrespective of the patient's age and the absence of constitutional symptoms of toxoplasmosis.

    Anabolic steroid abuse is common among athletes and is associated with a number of medical complications. We describe a case of a 27-year-old male bodybuilder with multiple hepatic adenomas induced by anabolic steroids. He initially presented with tumor hemorrhage and was treated with left lateral hepatic segmentectomy. Regression of the remaining tumors was observed with cessation of steroid use. However, 3 years and a half alter his initial hepatic segmentectomy, he presented with recurrent tumor enlargement and intraperitoneal hemorrhage in the setting of steroid abuse relapse. Given his limited hepatic reserve, he was conservatively managed with embolization of the right accessory hepatic artery.This is the first reported case of hepatic adenoma re-growth with recidivistic steroid abuse, complicated by life-threatening hemorrhage. While athletes and bodybuilders are often aware of the legal and social ramifications of steroid abuse, they should continue to be counseled about its serious medical risks.

  1. Troponin elevation in subarachnoid hemorrhage

    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.

    Congenital arteriovenous malformations (AVMs) often present with congestive heart failure. Such pathologic vascular structures typically occur in cranial, hepatic, or pulmonary locations and are usually associated with overlying external visible, tactile, or audible abnormalities. These vascular anomalies may also be associated with such complications as thromboembolic events, coagulopathy, and localized hemorrhage. We present a newborn infant with an occult but hemodynamically significant parascapular AVM who presented with an intraparenchymal brain hemorrhage, which we suspect to be a remote complication of the AVM.

    We analyzed 55 autopsy cases in 1,357 patients undergoing orthotopic liver transplantation at the University of Pittsburgh and found that 13 (23.6%) patients had intracranial bleeding, and five (9%) had infarcts. Eight patients had bleeding localized to one intracranial compartment: intracerebral hemorrhage (three patients); subarachnoid hemorrhage (three patients); and subdural hematoma (two patients). Five patients had combinations of multiple sites of bleeding: three with subarachnoid hemorrhage-intracerebral hemorrhage, one with subarachnoid hemorrhage-intracerebral hemorrhage-subdural hematoma, and one with subdural hematoma-intracerebral hemorrhage. Coexistent CNS infections (fungal or bacterial) were associated with hemorrhagic infarcts and intracerebral hemorrhage in four patients. Cerebral embolism and hemorrhagic infarction from bacterial endocarditis occurred in one patient. Five patients died of intracranial bleeding. Severe coagulopathy was the major cause of intracranial bleeding and was associated with systemic bleeding in 12 patients. Significant systemic or metabolic complications were present in all patients and masked the focal signs of the intracranial process in more than one half.

    1994-04-01

    The CT findings of 19 hemodialyzed patients with brain hemorrhage (BH) were evaluated. The 30-day mortality rate was 78.9%. The lesion locations in the 19 cases with BH were putaminal hemorrhage in 8 patients, putaminothalamic (mixed) hemorrhage in 7, thalamic hemorrhage in one, subcortical hemorrhage in one, and cerebellar hemorrhage in one. In the remaining patient, the bleeding was confined to the ventricular system. One remarkable CT finding was the formation of a massive hematoma in most cases. In some cases, the hematoma occupied the greater part of one cerebral hemisphere. Oral anticoagulants and/or antiplatelet drugs, and intravenous heparinization could produce massive accumulations of blood in the brain parenchyma. The second major finding was the low CT absorption values of the hematoma at the acute stage, as compared to that of hypertensive BH. This decreased absorption density resulted from a low hemoglobin concentration in the hematoma itself due to the severe anemia occurring in patients on long-term maintenance hemodialysis. (author).

    2012-07-01

    Full Text Available Abstract Introduction Therapeutic anticoagulation is an important treatment of thromboembolic complications, such as DVT, PE, and blunt cerebrovascular injury. Traumatic intracranial hemorrhage has traditionally been considered to be a contraindication to anticoagulation. Hypothesis Therapeutic anticoagulation can be safely accomplished in select patients with traumatic intracranial hemorrhage. Methods Patients who developed thromboembolic complications of DVT, PE, or blunt cerebrovascular injury were stratified according to mode of treatment. Patients who underwent therapeutic anticoagulation with a heparin infusion or enoxaparin (1 mg/kg BID were evaluated for neurologic deterioration or hemorrhage extension by CT scan. Results There were 42 patients with a traumatic intracranial hemorrhage that subsequently developed a thrombotic complication. Thirty-five patients developed a DVT or PE. Blunt cerebrovascular injury was diagnosed in four patients. 26 patients received therapeutic anticoagulation, which was initiated an average of 13 days after injury. 96% of patients had no extension of the hemorrhage after anticoagulation was started. The degree of hemorrhagic extension in the remaining patient was minimal and was not felt to affect the clinical course. Conclusion Therapeutic anticoagulation can be accomplished in select patients with intracranial hemorrhage, although close monitoring with serial CT scans is necessary to demonstrate stability of the hemorrhagic focus.

    After the surgical procedure of tonsillectomy, hemorrhage ranks among its serious postoperative complications. In this systematic review, we analyze hemorrhage following tonsillectomies performed using the coblation technique. 24 prospective, randomized, and controlled studies were included in the meta-analysis. Data of 796 patients who had undergone coblation tonsillectomy were analyzed. Hemorrhages occurred in 33 patients: 2 classified as primary and 26 as secondary hemorrhages. 5 could not be classified into either group. Overall, the total hemorrhage rate for the coblation procedure was 4.1% with a 95% confidence interval from 2.8 to 5.5%. The overall hemorrhage rate of 4.1% found in this meta-analysis shows that coblation is a safe and effective technique for tonsillectomies with a secondary bleeding rate similar to what is reported for comparable techniques such as bipolar diathermia.

    Objective. To investigate retrospectively the complications and associated factors of gynecological laparescopies.Methods. 1769 laparoscopic surgeries were carried out from January 1994 to October 1999 at our department. The procedures included 1421 surgeries of ovary and tube, 52 myomectomies and 296 cases of laproscopic-assisted vaginal hysterectomy (LAVH). A total of 312 patients had a history of prior laparotomy (17.6%). Results. Complications occured in 34 cases, the overall complication rate was 1.92%. Unintended laparotomies occured in 6 cases(0.34% ). 12 complications were associated with insertion of Veress needle or trocar and creation of pneumoperitoneum, including 5 severe emphysema and 7 vascular injuries, this figure represents 35.3% of all complications of this series. Five intraopemtive complications (14.7 % ) occured during the laparescopic surgery (3 severe bleedings, one bladder injury and one skin bum of leg caused by damaged electrode plate), laparotomy was re-quired in four of these cases. Seventeen complications occured during postoperative stage: 2 intraperitoneal hemor-rhages needing laparotomy, 2 bowel injuries, 4 nerve paresis and 9 febrile morbidities. Cordusions. Operative gynecologic laparoscopy is associated with acceptable morbidity rate, but can not be over-looked. Complication rate seems to be higher in advanced procedures such as LAVH.

    Full Text Available Cerebellar ataxias represent a wide group of neurological diseases secondary to dysfunctions of cerebellum or its associated pathways, rarely coursing with acute-onset acquired etiologies and chronic non-progressive presentation. We evaluated patients with acquired non-progressive cerebellar ataxia that presented previous acute or subacute onset. Clinical and neuroimaging characterization of adult patients with acquired non-progressive ataxia were performed. Five patients were identified with the phenotype of acquired non-progressive ataxia. Most patients presented with a juvenile to adult-onset acute to subacute appendicular and truncal cerebellar ataxia with mild to moderate cerebellar or olivopontocerebellar atrophy. Establishing the etiology of the acute triggering events of such ataxias is complex. Non-progressive ataxia in adults must be distinguished from hereditary ataxias.

    A 44 year old woman was healthy until January 3, 1986, when she had headache. On January 9, she developed gait ataxia and dysarthria. Cerebellar ataxia worsened rapidly. Aftar a week she could not sit without support and her consciousness was disturbed. Corticosteroid was administrated and consciousness proved alert, but cerebellar ataxia and dysarthria remained unchanged. The patient was found carcinoma of the lung in August 1986. Characteristic features of clinical and laboratory findings of this patient are acute progression, cerebrospinal fluid pleocytosis of 1,064/3 cells (860 mononuclear cell, 204 polymorphonuclear cell), and cerebellar swelling shown in computed tomography scanning. Though the mechanism of acute cerebellar degeneration is still uncertained, inflammatory process was supported to exist in cerebellum of this case.

    Unidentified bright objects (UBO) and tumors are well-known cerebellar abnormalities in neurofibromatosis type 1 (NF1). Literature reports on malformative cerebellar anomalies in neurofibromatosis type 1 (NF1), however, are scant. We retrospectively studied the clinical and neuroimaging findings of 5 patients with NF1 (4 females, age 6 to 29 years at last follow-up) and cerebellar anomalies. Cerebellar symptoms on neurological examination were mild or even not evident whereas learning disabilities were more or less pronounced in four patients. Two patients had cerebellar hypoplasia (diffusely enlarged cerebellar interfoliar spaces) and three cerebellar dysmorphias involving mainly one cerebellar hemisphere. In NF1, malformative cerebellar anomalies are rare (estimated prevalence of about 1%), but most likely underestimated and easily overlooked, because physicians tend to focus on more prevalent, obvious, and well-known findings such as optic pathway gliomas, other tumors, and UBO. This kind of cerebellar anomaly in NF1 has most likely a malformative origin, but the exact pathogenesis is unknown. The individual clinical significance is difficult to determine. We suggest that cerebellar anomalies should be systematically evaluated in neuroimaging studies of NF1 patients.

    The cerebellum is a somatotopically organized central component of the central nervous system well known to be involved with motor coordination and increasingly recognized roles in cognition and planning. Recent work in multiatlas labeling has created methods that offer the potential for fully automated 3-D parcellation of the cerebellar lobules and vermis (which are organizationally equivalent to cortical gray matter areas). This work explores the trade offs of using different statistical fusion techniques and post hoc optimizations in two datasets with distinct imaging protocols. We offer a novel fusion technique by extending the ideas of the Selective and Iterative Method for Performance Level Estimation (SIMPLE) to a patch-based performance model. We demonstrate the effectiveness of our algorithm, Non- Local SIMPLE, for segmentation of a mixed population of healthy subjects and patients with severe cerebellar anatomy. Under the first imaging protocol, we show that Non-Local SIMPLE outperforms previous gold-standard segmentation techniques. In the second imaging protocol, we show that Non-Local SIMPLE outperforms previous gold standard techniques but is outperformed by a non-locally weighted vote with the deeper population of atlases available. This work advances the state of the art in open source cerebellar segmentation algorithms and offers the opportunity for routinely including cerebellar segmentation in magnetic resonance imaging studies that acquire whole brain T1-weighted volumes with approximately 1 mm isotropic resolution.

  6. Cerebellar endocannabinoids: retrograde signaling from purkinje cells.

    The cerebellar cortex exhibits a strikingly high expression of type 1 cannabinoid receptor (CB1), the cannabinoid binding protein responsible for the psychoactive effects of marijuana. CB1 is primarily found in presynaptic elements in the molecular layer. While the functional importance of cerebellar CB1 is supported by the effect of gene deletion or exogenous cannabinoids on animal behavior, evidence for a role of endocannabinoids in synaptic signaling is provided by in vitro experiments on superfused acute rodent cerebellar slices. These studies have demonstrated that endocannabinoids can be transiently released by Purkinje cells and signal at synapses in a direction opposite to information transfer (retrograde). Here, following a description of the reported expression pattern of the endocannabinoid system in the cerebellum, I review the accumulated in vitro data, which have addressed the mechanism of retrograde endocannabinoid signaling and identified 2-arachidonoylglycerol as the mediator of this signaling. The mechanisms leading to endocannabinoid release, the effects of CB1 activation, and the associated synaptic plasticity mechanisms are discussed and the remaining unknowns are pointed. Notably, it is argued that the spatial specificity of this signaling and the physiological conditions required for its induction need to be determined in order to understand endocannabinoid function in the cerebellar cortex.

  7. Cerebellar liponeurocytoma: a case-report

    Directory of Open Access Journals (Sweden)

    K.V. Sreedhar Babu

    Full Text Available Cerebellar liponeurocytoma is a rare cerebellar neoplasm of adults with advanced neuronal / neurocytic and focal lipomatous differentiation, a low proliferative potential and a favorable clinical prognosis corresponding to World Health Organization grade I or II. Only a few cases have been described in the literature (approximately 20 cases by different names. A 48-years old female, presented with history of headache and dizziness associated with neck pain; restricted neck movements, drop attacks and occasional regurgitation of food since one year. Magnetic resonance imaging disclosed a right cerebellar mass lesion. Gross total resec- tion of the tumour was accomplished through a suboccipital craniotomy. The excised tissue was diagnosed as cerebellar liponeurocytoma, a rare entity, based on histopathological examination and immunohistochemistry. The morphological appearance of this neoplasm can be confused with that of oligodendroglioma, neurocytoma, ependymoma, medulloblastoma, solid hemangioblastoma and metastatic carcinomas etc., with unpredictable prognosis, which require postoperative radiotherapy, hence the importance of accurately diagnosing this rare neoplasm. This tumour should be added to the differential diagnosis of mass lesions of the posterior fossa.

  8. Cerebellar cortical inhibition and classical eyeblink conditioning.

    2002-02-01

    The cerebellum is considered a brain structure in which memories for learned motor responses (e.g., conditioned eyeblink responses) are stored. Within the cerebellum, however, the relative importance of the cortex and the deep nuclei in motor learning/memory is not entirely clear. In this study, we show that the cerebellar cortex exerts both basal and stimulus-activated inhibition to the deep nuclei. Sequential application of a gamma-aminobutyric acid type A receptor (GABA(A)R) agonist and a noncompetitive GABA(A)R antagonist allows selective blockade of stimulus-activated inhibition. By using the same sequential agonist and antagonist methods in behaving animals, we demonstrate that the conditioned response (CR) expression and timing are completely dissociable and involve different inhibitory inputs; although the basal inhibition modulates CR expression, the conditioned stimulus-activated inhibition is required for the proper timing of the CR. In addition, complete blockade of cerebellar deep nuclear GABA(A)Rs prevents CR acquisition. Together, these results suggest that different aspects of the memories for eyeblink CRs are encoded in the cerebellar cortex and the cerebellar deep nuclei.

    Although most cases of acute nonvariceal gastrointestinal hemorrhage either spontaneously resolve or respond to medical management or endoscopic treatment,there are still a significant number of patients who require emergency angiography and transcatheter treatment.Evaluation with noninvasive imaging such as nuclear scintigraphy or computed tomography may localize the bleeding source and/or confirm active hemorrhage prior to angiography.Any angiographic evaluation should begin with selective catheterization of the artery supplying the most likely site of bleeding,as determined by the available clinical,endoscopic and imaging data.If a hemorrhage source is identified,superselective catheterization followed by transcatheter microcoil embolization is usually the most effective means of successfully controlling hemorrhage while minimizing potential complications.This is now wellrecognized as a viable and safe alternative to emergency surgery.In selected situations transcatheter intra-arterial infusion of vasopressin may also be useful in controlling acute gastrointestinal bleeding.One must be aware of the various side effects and potential complications associated with this treatment,however,and recognize the high re-bleeding rate.In this article we review the current role of angiography,transcatheter arterial embolization and infusion therapy in the evaluation and management of nonvariceal gastrointestinal hemorrhage.

    Computerized tomography, carotid angiograms, and arteriography were used to diagnose several cases of cerebral hemorrhage following the use of phenylpropanolamine. The angiographic picture in one of the three cases was similar to that previously described in association with amphetamine abuse and pseudoephedrine overdose, both substances being chemically and pharmacologically similar to phenylpropanolamine. The study suggests that the arterial change responsible for symptoms may be due to spasm rather than arteriopathy. 14 references, 5 figures.

  12. Need for Continued Use of Anticoagulants After Intracerebral Hemorrhage.

    Estol, Conrado J.; Kase, Carlos S.

    2003-07-01

    One of the unsolved dilemmas in cerebrovascular disease is the ideal timing to restart anticoagulant therapy (ACT) safely in patients who have suffered an intracranial hemorrhage and have an indication to continue ACT. No randomized studies with evidence-based data are available to settle this issue. Only a few reports have been published; their shortcomings include small numbers of patients evaluated retrospectively, a broad spectrum of indications for ACT, different types of hemorrhage, and variable methods of reversing and restarting ACT. Despite this variability, most reports agree that 1) ACT has to be immediately reversed to decrease the risk of hemorrhage progression; 2) a period between 1 and 2 weeks appears sufficient to allow for management and monitoring of the hemorrhage off ACT; and 3) ACT can be safely restarted after the period off of treatment. A physician confronting a patient with intracranial hemorrhage and the need for ACT faces a situation of individually focused clinical decision making. The problem rests in balancing the risks of a worsening or recurring hemorrhage on one side, and the risk of thromboembolism on the other. From available information and personal experience, an unvalidated risk stratification can be proposed to categorize patients in low- and high-risk groups for hemorrhagic complications and embolic phenomena, assigning them to 5 or 15 days off ACT, respectively. Intermediate-risk patients can have ACT restarted in 5 to 15 days from the onset of the intracranial hemorrhage. Anticoagulation should be immediately reversed. Fresh frozen plasma is the standard treatment in most institutions. Prothrombin complex concentrate is an alternative, but issues of availability make its use impractical. The use of recombinant factor VIIa is an attractive new option.

    Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS. We report here on a case of HFRS that caused massive perirenal hematoma, and this was treated with superselective renal artery embolization.

    This article addresses the incidence of specific complications and, where possible, offers a preventive or management strategy. Injuries of the inferior alveolar and lingual nerves are significant issues that are discussed separately in this text. Surgical removal of third molars is often associated with postoperative pain, swelling, and trismus. Factors thought to influence the incidence of complications after third molar removal include age, gender, medical history, oral contraceptives, presence of pericoronitis, poor oral hygiene, smoking, type of impaction, relationship of third molar to the inferior alveolar nerve, surgical time, surgical technique, surgeon experience, use of perioperative antibiotics, use of topical antiseptics, use of intra-socket medications, and anesthetic technique. Complications that are discussed further include alveolar osteitis, postoperative infection, hemorrhage, oro-antral communication, damage to adjacent teeth, displaced teeth, and fractures.

  15. Hemorrhagic aspects of Gaucher disease.

    Science.gov (United States)

    Rosenbaum, Hanna

    2014-10-01

    Gaucher disease (GD) is an inherited lysosomal disorder, originating from deficient activity of the lysosomal enzyme glucocerebrosidase (GCase). Normally, GCase hydrolyzes glucocerebroside (GC) to glucose and ceramide; however, impaired activity of this enzyme leads to the accumulation of GC in macrophages, termed "Gaucher cells." Gaucher disease is associated with hepatosplenomegaly, cytopenias, skeletal complications and in some forms involves the central nervous system. Coagulation abnormalities are common among GD patients due to impaired production and chronic consumption of coagulation factors. Bleeding phenomena are variable (as are other symptoms of GD) and include mucosal and surgical hemorrhages. FOUR MAIN ETIOLOGICAL FACTORS ACCOUNT FOR THE HEMOSTATIC DEFECT IN GD: thrombocytopenia, abnormal platelet function, reduced production of coagulation factors, and activation of fibrinolysis. Thrombocytopenia relates not only to hypersplenism and decreased megakaryopoiesis by the infiltrated bone marrow but also to immune thrombocytopenia. Autoimmunity, especially the induction of platelet antibody production, might cause persistent thrombocytopenia. Enzyme replacement therapy reverses only part of the impaired coagulation system in Gaucher disease. Other therapeutic and supportive measures should be considered to prevent and/or treat bleeding in GD. Gaucher patients should be evaluated routinely for coagulation abnormalities especially prior to surgery and dental and obstetric procedures.

    Subarachnoid blood has been reported as a cause of chronic spinal arachnoiditis. Although syringomyelia has been thought to be caused by spinal arachnoiditis, reports of syringomyelia following aneurysmal subarachnoid hemorrhage (SAH) are very rare. We describe two patients with syringomyelia associated with chronic spinal arachnoiditis following SAH. From January 2001 to December 2010, 198 patients with aneurysmal SAH were treated at Kinki University School of Medicine. Two of the 198 patients had syringomyelia following aneurysmal SAH; thus the rate of syringomyelia associated with aneurysmal SAH was 1.0%. Patient 1 was a 54-year-old woman who presented with back pain, back numbness and gait disturbance 20 months after SAH. Her MRI revealed syringomyelia of the spinal cord from C2 to T10. She underwent shunting of the syrinx to the subarachnoid space. Patient 2 was a 49-year-old man, who was admitted to the hospital with headache, diplopia, hoarseness, dysphagia and ataxia five months after SAH. MRI revealed syringomyelia from the medulla oblongata to C6, and an enlargement of the lateral and fourth ventricles. After foramen magnum decompression and C1 laminectomy, a fourth ventricle-subarachnoid shunt was placed by insertion of a catheter. Spinal arachnoiditis and spinal syringomyelia are rare but important chronic complications after SAH.

    Alveolar hemorrhage (AH) is a rare syndrome that can often occur in autoimmune diseases, blood clotting disorders, infection or by acute inhalation injury, presenting rapid evolution and high mortality, especially with late diagnosis and treatment. Among the autoimmune diseases, there are reported cases in patients with primary antiphospholipid syndrome (PAPS), vasculitis and systemic lupus erythematosus (SLE). An early diagnosis is an essential tool in the successful management of this complication, requiring aggressive treatment based on vigorous immunosuppression and broad-spectrum antibiotic. We describe here a case of alveolar hemorrhage associated with glomerulonephritis as the open presentation in a patient with SLE.

    Postpartum hemorrhage (PPH) is a leading cause of maternal mortality worldwide. Recent advances in the management of severe bleeding for trauma patients may provide insight into PPH management, but must be applied with caution considering the significant differences between trauma and obstetric patients. In this review, we summarized evidence for current management strategies for patients with major obstetric hemorrhage, including (1) rapid laboratory assessment of coagulopathy, (2) early transfusion of plasma and high plasma-to-red blood cell transfusion ratios in massive PPH, and (3) use of tranexamic acid and fibrinogen concentrates in the setting of PPH complicated by coagulopathy.

    Imaging of the cerebellar cortex, deep cerebellar nuclei and their connectivity are gaining attraction, due to the important role the cerebellum plays in cognition and motor control. Atlases of the cerebellar cortex and nuclei are used to locate regions of interest in clinical and neuroscience studies. However, the white matter that connects these relay stations is of at least similar functional importance. Damage to these cerebellar white matter tracts may lead to serious language, cognitive and emotional disturbances, although the pathophysiological mechanism behind it is still debated. Differences in white matter integrity between patients and controls might shed light on structure-function correlations. A probabilistic parcellation atlas of the cerebellar white matter would help these studies by facilitating automatic segmentation of the cerebellar peduncles, the localization of lesions and the comparison of white matter integrity between patients and controls. In this work a digital three-dimensional probabilistic atlas of the cerebellar white matter is presented, based on high quality 3T, 1.25mm resolution diffusion MRI data from 90 subjects participating in the Human Connectome Project. The white matter tracts were estimated using probabilistic tractography. Results over 90 subjects were symmetrical and trajectories of superior, middle and inferior cerebellar peduncles resembled the anatomy as known from anatomical studies. This atlas will contribute to a better understanding of cerebellar white matter architecture. It may eventually aid in defining structure-function correlations in patients with cerebellar disorders.

    Objective To investigate the clinical, serological and radiographic characteristics of anti-cytoplasmic antibody (ANCA)-associated vasculitis (AASA) complicating diffuse alveolar hemorrhage (DAH). Methods Retrospective study on clinical and radiologic features, serologic parameters, treatment and prognosis was performed in five patients with AASV complicating DAH confirmed in Peking Union Hospital from January 2001 to May 2011. Results Of 5 patients with AASV complicating DAH,the causes were propylthiouracil (2 cases) and a single case for cefalexin,atrovastatin and carbamaz-epine,respectively. The clinical manifestations varied from fever, coughing, shortness of breath and hemoptysis to crackles found on physical examination. Bilateral patchy infiltrates and ground-glass opacities were shown on chest CT. The increase in erythrocyte sedimentation rate and C-reactive protein varied, as suggested by serologic examination. Positive perinuclear ANCA (p-ANCA) ,cytoplasmic ANCA (c-ANCA) or both was present in 3 cases and a single case each for the latter two conditions,respectively. Corticosteroid was administrated in all cases,of which 2 received oral prednisone treatment,2 were treated with combined corticosteroid and cyclophosphamide, and a single case was treated with combined corticosteroid and plasma exchange therapy for three times. Conclusion Although diagnosis of AASV complicating DAH proves to be difficult , consideration should be prompted in case of emerging shortness of breath, hemoptysis and pulmonary infiltrates in those with confirmed history of concomitant medication.%目的 探讨药物诱发的中性粒细胞浆抗体(ANCA)相关小血管炎(AASV)合并弥漫性肺泡出血(DAH)的临床、血清学和影像学特征.方法 回顾性分析北京协和医院2001年1月至2011年5月收治的5例AASV合并DAH患者的临床、肺部影像学表现、血清学指标、治疗及预后.结果 5例AASV合并DAH患者中,丙基硫氧嘧啶(PTU)引起的2例,

  8. Pseudoaneurysm associated with complicated pancreatic pseudocysts

    Directory of Open Access Journals (Sweden)

    Laura Larrey-Ruiz

    Full Text Available A pseudoaneurysm associated with a pseudocyst is a serious and unusual complication of chronic pancreatitis. Its treatment is complex due to its elevated mortality and the need for multidisciplinary management. Initial measures consist of locating the hemorrhage through computerized dynamic tomography and arteriography. The treatment of choice is controversial due to the lack of controlled studies. For managing hemorrhages in stable patients, the most accepted initial measure is currently arterial embolization. In the event of failure of the same, hemodynamic instability or the impossibility of drainage of the pseudocyst, surgery is the subsequent therapeutic option.

    Endogenous circulating anticoagulants are unusual in children without a congenital factor deficiency. In particular, the lupus anticoagulant has only rarely been reported in children. Despite its functioning in vitro to prolong the partial thromboplastin time, patients more frequently have problems with thrombosis than bleeding, unless there is a coexistent prothrombin deficiency or thrombocytopenia. We report the cases of three children with the lupus anticoagulant. Two children had associated thromboses. One had a thrombosis of the iliofemoral system and the other had a partial Budd-Chiari syndrome, a thrombosis of the deep calf veins and ureteric obstruction. The third child had a concomitant prothrombin deficiency and bleeding after tooth extraction. Associated findings in these patients included a positive antinuclear antibody test in two, a positive anti-DNA antibody test in two, a false-positive VDRL test in two, and an antiphospholipid antibody test in two.

    Red blood cell transfusions are used to treat hemorrhage and to improve oxygen delivery to tissues. Transfusion of red blood cells should be based on the patient's clinical condition. Indications for transfusion include symptomatic anemia (causing shortness of breath, dizziness, congestive heart failure, and decreased exercise tolerance), acute sickle cell crisis, and acute blood loss of more than 30 percent of blood volume. Fresh frozen plasma infusion can be used for reversal of anticoagulant effects. Platelet transfusion is indicated to prevent hemorrhage in patients with thrombocytopenia or platelet function defects. Cryoprecipitate is used in cases of hypofibrinogenemia, which most often occurs in the setting of massive hemorrhage or consumptive coagulopathy. Transfusion-related infections are less common than noninfectious complications. All noninfectious complications of transfusion are classified as noninfectious serious hazards of transfusion. Acute complications occur within minutes to 24 hours of the transfusion, whereas delayed complications may develop days, months, or even years later.

    We report a case of a 31-week-gestation male newborn who died soon after birth from intractable respiratory failure and persistent pulmonary hypertension. The pregnancy had been complicated by intermittent bleeding between 13 and 20 weeks' gestation, attributed to peripheral placental separation, as well as bilateral fetal adrenal hemorrhage, first detected at 17 weeks' gestation. Postmortem examination revealed small, calcified adrenal glands as well as several remote cerebral and cerebellar infarcts. The lungs were hypoplastic (lung weight/body weight ratio: 1.64%; 10th percentile for 28-36 weeks' gestation: 2.27%) and distorted by exaggerated lobulation. Microscopically, the lungs exhibited several developmental anomalies, including focal acinar dysgenesis suggestive of arrested development in the pseudoglandular stage of development (8-16 weeks' gestation) (mainly in the upper lobes), and features of bronchial obstruction, including focal lobular hyperplasia and microcystic maldevelopment (mainly in the lower lobes). The adrenal and cerebral findings were consistent with a severe early-gestation hypoxic-ischemic insult, likely related to peripheral placental separation and chronic abruption. The co-occurrence and timing of these well-recognized hypoxic lesions provide further evidence that certain developmental lung anomalies, such as focal acinar dysplasia, focal lobular hyperplasia, and microcystic maldevelopment, may, at least in some cases, have a hypoxic/ischemic etiology.

  13. Subarachnoid hemorrhage due to retained lumbar drain.

    2011-12-01

    Intrathecal spinal catheters (lumbar drains) are indicated for several medical and surgical conditions. In neurosurgical procedures, they are used to reduce intracranial and intrathecal pressures by diverting CSF. They have also been placed for therapeutic access to administer drugs, and more recently, vascular surgeons have used them to improve spinal cord perfusion during the treatment of thoracic aortic aneurysms. Insertion of these lumbar drains is not without attendant complications. One complication is the shearing of the distal end of the catheter with a resultant retained fragment. The authors report the case of a 65-year-old man who presented with a subarachnoid hemorrhage due to the migration of a retained lumbar drain that sheared off during its removal. To the best of the authors' knowledge, this is the first case of rostral migration of a retained intrathecal catheter causing subarachnoid hemorrhage. The authors review the literature on retained intrathecal spinal catheters, and their findings support either early removal of easily accessible catheters or close monitoring with serial imaging.

    The cerebellum plays an important role in motor control and is also involved in cognitive processes. Cerebellar function is specialized by location, although the exact topographic functional relationship is not fully understood. The spinocerebellar ataxias are a group of neurodegenerative diseases that cause regional atrophy in the cerebellum, yielding distinct motor and cognitive problems. The ability to study the region-specific atrophy patterns can provide insight into the problem of relating cerebellar function to location. In an effort to study these structural change patterns, we developed a toolbox in MATLAB to provide researchers a unique way to visually explore the correlation between cerebellar lobule shape changes and function loss, with a rich set of visualization and analysis modules. In this paper, we outline the functions and highlight the utility of the toolbox. The toolbox takes as input landmark shape representations of subjects' cerebellar substructures. A principal component analysis is used for dimension reduction. Following this, a linear discriminant analysis and a regression analysis can be performed to find the discriminant direction associated with a specific disease type, or the regression line of a specific functional measure can be generated. The characteristic structural change pattern of a disease type or of a functional score is visualized by sampling points on the discriminant or regression line. The sampled points are used to reconstruct synthetic cerebellar lobule shapes. We showed a few case studies highlighting the utility of the toolbox and we compare the analysis results with the literature.

    Full Text Available The dominantly inherited ataxias, also known as Spino-cerebellar ataxias (SCAs, are rapidly expanding entities. New mutations are being identified at remarkable regularity. Recent awareness of molecular abnormalities in SCAs has addressed some of the long sought questions, but gaps in knowledge still exist. Three major categories of SCAs, according to molecular mechanisms, have evolved over recent few years: Polyglutamate expansion ataxia, non-coding zone repeat ataxia, and ataxia due to conventional mutation. Using the fulcrum of these mechanisms, the article provides an update of SCAs. Shared and specific clinical features, genetic abnormalities, and possible links between molecular abnormalities and cerebellar degeneration have been discussed. Emphasis has been placed on the mechanisms of polyglutamate toxicity.

    A 50-year-old AIDS patient with a CD4 T-cell count of 114/mm(3) was admitted with cerebellar symptoms of left CN XI weakness, wide-based gait with left-sided dysmetria, abnormal heel-knee-shin test, and dysdiadochokinesia. MRI showed region of hyperintensity in the left inferior cerebellar hemisphere involving the cortex and underlying white matter. Serological tests for HSV1, HSV2, and syphilis were negative. Her CSF contained high protein content and a WBC of 71/mm(3), predominantly lymphocytes. The CSF was also negative for cryptococcal antigen and VDRL. CSF culture did not grow microbes. CSF PCR assay was negative for HSV1 and HSV2 but was positive for JC virus (1,276 copies). The most likely diagnosis is granule cell neuronopathy (GCN), which can only be definitively confirmed with biopsy and immunohistochemistry.

    Full Text Available Purpose. Formation of a tracheoinnominate artery fistula (TIF and consecutive hemorrhage is a rare and life-threatening complication with high mortality. Warning symptoms can be absent. The current literature contains only few considerations for misleading signs, especially in cases where the contact between the tissue and the cannula is tight. Method and Results. We report two cases of life-threatening hemorrhages that appeared six days and two months after percutaneous dilatational tracheostomy (PDT in two patients, respectively. In these cases, diagnosis of tracheoinnominate artery fistula (TIF was difficult. Tracheal ring fracture after PDT and pressure ulceration caused by cannula were implicated in TIF formation. The cannula was overblocked to buy time before surgical closure. Both patients survived without any additional neurological deficiency. Conclusion. Massive hemorrhage in patients after tracheostomy is likely due to TIF. Ultrasound scanning before PDT and careful periodical followup of the trachea are required.

  1. Memory consolidation in the cerebellar cortex.

    Directory of Open Access Journals (Sweden)

    Daniel O Kellett

    Full Text Available Several forms of learning, including classical conditioning of the eyeblink, depend upon the cerebellum. In examining mechanisms of eyeblink conditioning in rabbits, reversible inactivations of the control circuitry have begun to dissociate aspects of cerebellar cortical and nuclear function in memory consolidation. It was previously shown that post-training cerebellar cortical, but not nuclear, inactivations with the GABAA agonist muscimol prevented consolidation but these findings left open the question as to how final memory storage was partitioned across cortical and nuclear levels. Memory consolidation might be essentially cortical and directly disturbed by actions of the muscimol, or it might be nuclear, and sensitive to the raised excitability of the nuclear neurons following the loss of cortical inhibition. To resolve this question, we simultaneously inactivated cerebellar cortical lobule HVI and the anterior interpositus nucleus of rabbits during the post-training period, so protecting the nuclei from disinhibitory effects of cortical inactivation. Consolidation was impaired by these simultaneous inactivations. Because direct application of muscimol to the nuclei alone has no impact upon consolidation, we can conclude that post-training, consolidation processes and memory storage for eyeblink conditioning have critical cerebellar cortical components. The findings are consistent with a recent model that suggests the distribution of learning-related plasticity across cortical and nuclear levels is task-dependent. There can be transfer to nuclear or brainstem levels for control of high-frequency responses but learning with lower frequency response components, such as in eyeblink conditioning, remains mainly dependent upon cortical memory storage.

    Three ocular complications directly related to orbital venography are described, one resulting in permanent loss of vision,. The patient had lymphangioma of the orbit which evidently had bled secondary to increased venous pressure and injection of contrast bolus. Both of the 2 patients with transient visual disturbances had diabetic retinopathy. The common factor is felt to be an imparied vascular bed which cannot meet the stress of increased venous pressure and contrast medium injection. Conditions which predispose to ocular-orbital stasis and/or hemorrhage are discussed.

  3. An integrator circuit in cerebellar cortex.

    2013-09-01

    The brain builds dynamic models of the body and the outside world to predict the consequences of actions and stimuli. A well-known example is the oculomotor integrator, which anticipates the position-dependent elasticity forces acting on the eye ball by mathematically integrating over time oculomotor velocity commands. Many models of neural integration have been proposed, based on feedback excitation, lateral inhibition or intrinsic neuronal nonlinearities. We report here that a computational model of the cerebellar cortex, a structure thought to implement dynamic models, reveals a hitherto unrecognized integrator circuit. In this model, comprising Purkinje cells, molecular layer interneurons and parallel fibres, Purkinje cells were able to generate responses lasting more than 10 s, to which both neuronal and network mechanisms contributed. Activation of the somatic fast sodium current by subthreshold voltage fluctuations was able to maintain pulse-evoked graded persistent activity, whereas lateral inhibition among Purkinje cells via recurrent axon collaterals further prolonged the responses to step and sine wave stimulation. The responses of Purkinje cells decayed with a time-constant whose value depended on their baseline spike rate, with integration vanishing at low ( 30 per s). The model predicts that the apparently fast circuit of the cerebellar cortex may control the timing of slow processes without having to rely on sensory feedback. Thus, the cerebellar cortex may contain an adaptive temporal integrator, with the sensitivity of integration to the baseline spike rate offering a potential mechanism of plasticity of the response time-constant.

    The vascular architecture of the human cerebellar meninges was investigated. The surface meninges were poor in vasculature. In the sulci, the meninges were highly vascular but had few capillaries. The venous blood vessels gave long side branches at right angles to the parent vessels in a cruciform pattern, running horizontally along the cerebellar sulci. They were situated at the origin of the secondary or tertiary sulci. Anastomoses between these horizontal branches gave a crosshatched appearance. Short branches often extended to the bases of the sulci, terminating in T-shaped bifurcations with numerous tiny branches, like the roots of a tree. The arteries ran perpendicular to venous branches which were parallel to each other exclusively along the sagittal plane. These arteries bifurcated to straddle the horizontally running veins at the origin of the secondary or tertiary sulci. They gave off many small branches like teeth of a fork from each artery in the secondary or tertiary sulci after they bifurcated to straddle the venous branches and penetrated the cerebellar cortex at the bases of sulci. These fork-like ramifications in the bases of the sulci were most likely responsible for the ready development of pronounced ischemic state. They might also play an important role in the occurrence of ischemic damage at the bases of sulci in cases of severe generalized ischemia.

  5. Fusiform superior cerebellar artery aneurysm treated with STA-SCA bypass and trapping

    2014-01-01

    Full Text Available Background: Fusiform aneurysms of cerebellar arteries are rare. Different surgical techniques to address these challenging lesions have been described, and their application depends on whether the goal is to maintain the flow in the parent vessel or to occlude it. Case Description: The authors reported a case of a fusiform aneurysm located in the lateral pontomesencephalic segment of the superior cerebellar artery (SCA in a 32-year-old man who presented with subarachnoid hemorrhage. The patient was subjected to aneurysm trapping followed by a bypass between the superficial temporal artery (STA and SCA and had an uneventful recovery. Conclusions: Although only a few cases of fusiform aneurysms in the supracerebellar artery have been reported in the literature, the treatment strategies adopted were diverse. In selected cases of patients in good neurological condition with ruptured fusiform aneurysms at the proximal segments of SCA and who have poor evidence of collateral supply, the possibility of a STA-SCA bypass with aneurysm trapping must be considered. A review of the current treatment modalities of this pathology is also presented.

    2015-01-01

    The cerebellum is one of the most consistent sites of abnormality in autism spectrum disorder (ASD) and cerebellar damage is associated with an increased risk of ASD symptoms, suggesting that cerebellar dysfunction may play a crucial role in the etiology of ASD. The cerebellum forms multiple closed-loop circuits with cerebral cortical regions that underpin movement, language, and social processing. Through these circuits, cerebellar dysfunction could impact the core ASD symptoms of social and communication deficits and repetitive and stereotyped behaviors. The emerging topography of sensorimotor, cognitive, and affective subregions in the cerebellum provides a new framework for interpreting the significance of regional cerebellar findings in ASD and their relationship to broader cerebro-cerebellar circuits. Further, recent research supports the idea that the integrity of cerebro-cerebellar loops might be important for early cortical development; disruptions in specific cerebro-cerebellar loops in ASD might impede the specialization of cortical regions involved in motor control, language, and social interaction, leading to impairments in these domains. Consistent with this concept, structural, and functional differences in sensorimotor regions of the cerebellum and sensorimotor cerebro-cerebellar circuits are associated with deficits in motor control and increased repetitive and stereotyped behaviors in ASD. Further, communication and social impairments are associated with atypical activation and structure in cerebro-cerebellar loops underpinning language and social cognition. Finally, there is converging evidence from structural, functional, and connectivity neuroimaging studies that cerebellar right Crus I/II abnormalities are related to more severe ASD impairments in all domains. We propose that cerebellar abnormalities may disrupt optimization of both structure and function in specific cerebro-cerebellar circuits in ASD.

    2001-10-01

    The most frequent type of cerebellar infarcts involved the posterior inferior cerebellar artery (PICA) and superior cerebellar artery territories but bilateral involvement of lateral or medial branches of PICA is extremely rare. In this report, we present a 55-year-old male who admitted to hospital with vomiting, nausea and dizziness. On examination left-sided hemiparesia and ataxic gait were detected. Infarct on bilateral medial branch of PICA artery territories was found out with cranial magnetic resonance imaging (MRI) technique and 99% stenosis of the left vertebral artery was found out with digital subtraction arteriography. The patient was put on heparin treatment. After 3 weeks, his complaints and symptoms had disappeared except for mild gait ataxia.

    The aim of this study was to specify whether cerebellar lesions cause visuospatial impairments in children. The study sample consisted of 40 children with low-grade cerebellar astrocytoma, who underwent surgical treatment and 40 healthy controls matched with regard to age and sex. Visuospatial abilities were tested using the spatial WISC-R subtests (Block Design and Object Assembly), Rey-Osterrieth Complex Figure, Benton Judgment of Line Orientation Test, PEBL Mental Rotation Task, and Benton Visual Retention Test. To exclude general diffuse intellectual dysfunction, the WISC-R Verbal Intelligence IQ, Performance IQ, and Full-Scale IQ scores were analysed. Post-surgical medical consequences were measured with the International Cooperative Ataxia Rating Scale. Compared to controls, the cerebellar group manifested problems with mental rotation of objects, visuospatial organization, planning, and spatial construction processes which could not be explained by medical complications or general intellectual retardation. The intensity of visuospatial syndrome highly depends on cerebellar lesion side. Patients with left-sided cerebellar lesions display more severe spatial problems than those with right-sided cerebellar lesions. In conclusion, focal cerebellar lesions in children affect their visuospatial ability. The impairments profile is characterized by deficits in complex spatial processes such as visuospatial organization and mental rotation, requiring reconstruction of visual stimuli using the imagination, while elementary sensory analysis and perception as well as spatial processes requiring direct manipulation of objects are relatively better preserved. This pattern is analogous to the one previously observed in adult population and appears to be typical for cerebellar pathology in general, regardless of age.

    A 7-year-old boy from suburban Baltimore who presented with cerebellar ataxia and headaches was found by magnetic resonance imaging to have multiple cerebellar enhancing lesions. He had no history of tick exposure. He was initially treated with steroids for presumptive postinfectious encephalitis. Lyme disease was diagnosed 10 weeks later after arthritis developed. Testing of the cerebrospinal fluid obtained at the time cerebellar ataxia was diagnosed revealed intrathecal antibody production to Borrelia burgdorferi. Treatment with intravenous antibiotics led to rapid resolution of persistent cerebellar findings.

    2009-12-15

    In the last two decades, a growing body of research showing cerebellar involvement in an increasing number of nonmotor tasks and systems has prompted an expansion of speculations concerning the function of the cerebellum. Here, we tested the predictions of a hypothesis positing cerebellar involvement in sensory data acquisition. Specifically, we examined the effect of global cerebellar degeneration on primary auditory sensory function by means of a pitch discrimination task. The just noticeable difference in pitch between two tones was measured in 15 healthy controls and in 15 high functioning patients afflicted with varying degrees of global cerebellar degeneration caused by hereditary, idiopathic, paraneoplastic, or postinfectious pancerebellitis. Participants also performed an auditory detection task assessing sustained attention, a test of verbal auditory working memory, and an audiometric test. Patient pitch discrimination thresholds were on average five and a half times those of controls and were proportional to the degree of cerebellar ataxia assessed independently. Patients and controls showed normal hearing thresholds and similar performance in control tasks in sustained attention and verbal auditory working memory. These results suggest there is an effect of cerebellar degeneration on primary auditory function. The findings are consistent with other recent demonstrations of cerebellar-related sensory impairments, and with robust cerebellar auditorily evoked activity, confirmed by quantitative meta-analysis, across a range of functional neuroimaging studies dissociated from attention, motor, affective, and cognitive variables. The data are interpreted in the context of a sensory hypothesis of cerebellar function.

    We report on the complication of gastroesophageal reflux (GER) in four patients with lower brainstem dysfunction. These patients suffered from perinatal asphyxia, cerebellar hemorrhage, or congenital dysphagia of unknown origin and showed facial nerve palsy, inspiratory stridor due to vocal cord paralysis, central sleep apnea, and dysphagia, in various combinations. Naso-intestinal tube feeding was introduced in all of the patients due to recurrent vomiting and aspiration pneumonia resulting from GER. T2-weighted magnetic resonance (MR) imaging revealed symmetrical high intensity lesions in the tegmentum of the lower pons and the medulla oblongata in two of the patients, and pontomedullary atrophy in another patient. In normal subjects, lower esophageal sphincter contraction is provoked by distension of the gastric wall, through a vago-vagal reflex. Since this reflex arc involves the solitary tract nucleus, where the swallowing center is located, the association of dysphagia and GER in the present patients is thought to result from the lesions in the tegmentum of medulla oblongata. We propose the term "dysphagia-GER complex" to describe the disturbed motility of the upper digestive tract due to lower brainstem involvement. In children with brainstem lesions, neurological assessment of GER is warranted, in addition to the examination of other signs of brainstem dysfunction, including dysphagia and respiratory disturbance.

    2015-03-01

    Full Text Available Ventriculoperitoneal shunt is a routinely performed treatment in neurosurgical department. Intracerebral hemorrhage, as a complication after shunt catheterization, is really rare but with high mortality. In this study, we reported a case of a 74-year-old man who suffered from repeated intracerebral hemorrhage after ventriculoperitoneal shunt. The first hemorrhage happened 63 h after the 1st surgery, and most hematomas were located in the ipsilateral occipital lobe and intraventricles, along the ventricular catheter. Fresh blood clot casts blocked the external ventricular draining catheter, which was inserted into the right front horn during the 3rd surgery, indicating new intraventricular bleeding happened. A large hematoma in ipsilateral frontal lobe was detected on the 3rd day after the removal of external ventricular draining catheter. Different hemorrhagic locations and time points were encountered on the same case. We discussed the possible causes of repeated hemorrhage for this case, and the pre-operative preparation including risk evaluation in future clinical work.

    Warfarin is a widely used anticoagulant. Interindividual differences in drug response, a narrow therapeutic range and the risk of bleeding render warfarin difficult to use clinically. An 18-year-old woman with antiphospholipid syndrome received long-term warfarin therapy for a recurrent deep vein thrombosis. Six years later, she developed right flank pain. We diagnosed intrahepatic and subgaleal hemorrhages secondary to anticoagulation therapy. After stopping oral anticoagulation, a follow-up computed tomography showed improvement in the hemorrhage. After restarting warfarin because of a recurrent thrombosis, the intrahepatic hemorrhage recurred. We decided to start clopidogrel and hydroxychloroquine instead of warfarin. The patient has not developed further recurrent thrombotic or bleeding episodes. Intrahepatic hemorrhage is a very rare complication of warfarin, and our patient experienced intrahepatic and subgaleal hemorrhage although she did not have any risk factors for bleeding or instability of the international normalized ratio control.

    Late hemorrhagic disease of the newborn (HDN) is a rare complication of vitamin-K deficiency and is especially associated with intracranial hemorrhage. It may also occur in infants who received vitamin-K prophylaxis at birth. Here, we reported a case of late HDN with frontal lobe hemorrhage due to vitamin-K deficiency. This form of intracranial hemorrhage of late HDN has been reported in the literature very rarely. We conclude that the efficiency of single-dose vitamin-K prophylaxis should be revaluated.

    A retrospective evaluation of embolotherapy in patients with arterial liver hemorrhages was carried out. Twenty-six patients, ranging in age from 10 days to 77 years with active arterial liver hemorrhages, underwent non-surgical embolotherapy. Bleeding was attributed to trauma (n = 21), tumor (n = 3), pancreatitis (n = 1), or unknown cause (n = 1). Twenty-nine embolizations were performed via a transfemoral (n = 26) or biliary (n = 2) approach. One bare Wallstent was placed into the common hepatic artery via to an axillary route to cover a false aneurysm due to pancreatitis. Treatment was controlled in 4 patients by cholangioscopy (n = 2) or by intravascular ultrasound (n = 2). Prior surgery had failed in 3 patients. Intervention controlled the hemorrhage in 24 of 26 (92 %) patients within 24 h. Embolotherapy failed in 1 patient with pancreatic carcinoma and occlusion of the portal vein. In 1 patient with an aneurysm of the hepatic artery treated by Wallstent insertion, total occlusion was not achieved in the following days, as demonstrated by CT and angiography. However, colour Doppler flow examination showed no flow in the aneurysm 6 months later. Complications were one liver abscess, treated successfully by percutaneous drainage for 10 days, and one gallbladder necrosis after superselective embolization of the cystic artery. Embolization is a effective tool with a low complication rate in the treatment of liver artery hemorrhage, even in patients in whom surgery has failed. (orig.) (orig.) With 2 figs., 26 refs.

    BACKGROUND: Post-pancreaticoduodenectomy (PD) hemorrhage (PPH) is an uncommon but serious complication. This retrospective study analyzed the risk factors, managements and outcomes of the patients with PPH. METHODS: A total of 840 patients with PD between 2000 and 2010 were retrospectively analyzed. Among them, 73 patients had PPH: 19 patients had early PPH and 54 had late PPH. The assessment included the preoperative history of disease, pancreatic status and surgical techniques. Other postoperative complications were also evaluated. RESULTS: The incidence of PPH was 8.7% (73/840). There were no independent risk factors for early PPH. Male gender (OR=4.40, P=0.02), diameter of pancreatic duct (OR=0.64, P=0.01), end-to-side invagination pancreaticojejunostomy (OR=5.65, P=0.01), pancreatic fistula (OR=2.33, P=0.04) and intra-abdominal abscess (OR=12.19, P CONCLUSIONS: Careful and ongoing observation of hemorrhagic signs, especially within the first 24 hours after PD or within the course of pancreatic fistula or intra-abdominal abscess, is recommended for patients with PD and a prompt management is necessary. Although endoscopy and angiography are the standard procedures for the management of PPH, surgical approach is still irreplaceable. Aggressive prevention of hemorrhagic shock and re-hemorrhage is the key to treat PPH.

    Full Text Available Cesarean scar pregnancy (CSP and cesarean scar dehiscence (CSD are the most dreaded complications of cesarean scar (CS. As the incidence of CS is increasing worldwide, so is the incidence of CSP, especially in cases with assisted reproduction techniques. It is of utmost importance to diagnose CSP in the early first trimester, as it can lead to myometrial rupture with fatal outcome. On the other hand, CSD may be encountered during pregnancy or in the postpartum period. CSD in the postpartum period is very rare and can cause secondary postpartum hemorrhage (PPH leading to increased maternal morbidity or even death if not diagnosed and managed promptly. Both complications can be diagnosed on ultrasonography (USG and confirmed on magnetic resonance imaging (MRI. These two conditions carry high morbidity and mortality. In this article, we highlight the role of imaging in the early diagnosis and management of these conditions.

    Spontaneous non-traumatic intracerebral hemorrhage (ICH) is associated with high morbidity and mortality throughout the world with no proven effective treatment. Majority of hematoma expansion occur within 4 h after symptom onset and is associated with early deterioration and poor clinical outcome. There is a vital role of ultra-early hemostatic therapy in ICH to limit hematoma expansion. Patients at risk for hematoma expansion are with underlying hemostatic abnormalities. Treatment strategy should include appropriate intervention based on the history of use of antithrombotic use or an underlying coagulopathy in patients with ICH. For antiplatelet-associated ICH, recommendation is to discontinue antiplatelet agent and transfuse platelets to those who will undergo neurosurgical procedure with moderate quality of evidence. For vitamin K antagonist-associated ICH, administration of 3-factor or 4-factor prothrombin complex concentrates (PCCs) rather than fresh frozen plasma to patients with INR >1.4 is strongly recommended. For patients with novel oral anticoagulant-associated ICH, administering activated charcoal to those who present within 2 h of ingestion is recommended. Idarucizumab, a humanized monoclonal antibody fragment against dabigatran (direct thrombin inhibitor) is approved by FDA for emergency situations. Administer activated PCC (50 U/kg) or 4-factor PCC (50 U/kg) to patients with ICH associated with direct thrombin inhibitors (DTI) if idarucizumab is not available or if the hemorrhage is associated with a DTI other than dabigatran. For factor Xa inhibitor-associated ICH, administration of 4-factor PCC or aPCC is preferred over recombinant FVIIa because of the lower risk of adverse thrombotic events. PMID:28360881

    Superficial siderosis of the central nervous system (CNS) is a rare disorder caused by deposition of hemosiderin in neuronal tissue in the subpial layer of the CNS due to slow subarachnoid or intraventricular hemorrhage. The most common neurologic manifestations include progressive gait ataxia, sensorineural hearing loss, and corticospinal tract signs. We present a case of superficial siderosis in a 43-year-old man who presented to the Emergency Department with sudden onset bilateral visual deterioration and a loss of consciousness. A hemorrhagic giant prolactinoma was diagnosed based on brain CT scan, T1-weighted MRI, and an endocrine blood examination. Susceptibility-weighted non-contrast MRI showed pathognomonic signs of superficial siderosis in the form of a hypointensity rim surrounding the brainstem, cerebellar fissures, and cranial nerves VII and VIII. This report demonstrates that superficial siderosis can be caused by pituitary apoplexy.

    We tried transcatheter arterial embolization for lower gastrointestinal hemorrhage due to radiation colitis. In this case, colostomy and endoscopic therapy were not effective. We succeeded in arresting the hemorrhage without any complications. Transcatheter embolization is a low-invasive and safe method of treatment. For prevention of inflammation and iatrogenic abscess formation, we repeated this therapy and we tried arterial injection of antibiotics and steroid. And so, this therapy is one of the effective methods. (author)

    During a Plasmodium chabaudi infection in interleukin-10 (IL-10) knockout mice, there is greater parasite sequestration, more severe cerebral edema, and a high frequency of cerebral hemorrhage compared with infection of C57BL/6 mice. Anti-tumor necrosis factor alpha treatment ameliorated both cerebral edema and hemorrhages, suggesting that proinflammatory responses contributed to cerebral complications in infected IL-10−/− mice.

    This study focuses on comparison of computed tomography and ultrasound in premature infants with intracranial hemorrhage and its complications. It was determined that close correlation (95%) exists between CT and ultrasound for evaluations of ventriculomegaly. Although there is reasonable correlation for the identification and localization of periventricular, intraventricular and choroidal hemorrhages, ultrasound defined such lesions at higher rates. Subarachnoid blood and periventricular edema were diagnosed better or exclusively by CT.

    Full Text Available Chickenpox is an acute viral infectious disease that is highly contagious and very common in children. When it occurs in adults, age increases severity, with complications that can lead to death in a short period of time. Among the most lethal complications we can find pneumonia and bronchopneumonia, injuries overinfection caused by streptococci and staphylococci with severe sepsis, diverse bleeding, encephalitis, shock, hemorrhagic nephritis with renal failure and necrotizing fasciitis, among others. The case of an 83 years old male patient, with a history of chronic obstructive pulmonary disease and ischemic cerebrovascular atherosclerotic disease that contracted chickenpox and whose evolution was very rapid, with acute respiratory failure and bronchopneumonia massive hemorrhagic shock, to the point of death, is presented. Given the increased incidence of chickenpox, according to reports of the Pedro Kouri Institute of Tropical Medicine, we decided to have this case published.

    This study was conducted to evaluate the clinical profile and outcome in late hemorrhagic disease of the newborn (HDN) with particular reference to intracranial hemorrhage. Infants (n = 42) presenting with late HDN from January 1998 to December 2001 were studied. Majority (76%) were in the age group of 1-3 months. All were term babies on exclusive breast-feeding and none received vitamin K at birth. 71% patients presented with intracranial hemorrhage, commonest site being intracerebral and multiple ICH. Visible external bleeding was noted in 1/3rd of patients only. Three patients expired. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. Isolated intracranial hemorrhage is a common mode of presentation.

    Vasospasm and re-bleeding after subarachnoid hemorrhage from ruptured intracranial aneurysm are devastating complication that can severely affect the outcome of the patients. We are presenting a series of total number of 224 patients treated and operated at our Department due to subarachnoid hemorrhage, out of which certain number developed vasospasm and re-bleeding. We are evaluating the effect of these complications on the outcome of the patients according to the Glasgow Outcome Scale at the day of discharge. In our experience both vasospasm and ReSAH can significantly influence the outcome of patients with subarachnoid hemorrhage from ruptured intracranial aneurysm.

    Cerebellar cortical infarct cavities are a newly recognised entity associated with atherothromboembolic cerebrovascular disease and worse physical functioning. We aimed to investigate the relationship of cerebellar cortical infarct cavities with symptomatic vertebrobasilar ischaemia and with vascular risk factors. We evaluated the MR images of 46 patients with a recent vertebrobasilar TIA or stroke and a symptomatic vertebral artery stenosis ≥50 % from the Vertebral Artery Stenting Trial (VAST) for the presence of cerebellar cortical infarct cavities ≤1.5 cm. At inclusion in VAST, data were obtained on age, sex, history of vertebrobasilar TIA or stroke, and vascular risk factors. Adjusted risk ratios were calculated with Poisson regression analyses for the relation between cerebellar cortical infarct cavities and vascular risk factors. Sixteen out of 46 (35 %) patients showed cerebellar cortical infarct cavities on the initial MRI, and only one of these 16 patients was known with a previous vertebrobasilar TIA or stroke. In patients with symptomatic vertebrobasilar ischaemia, risk factor profiles of patients with cerebellar cortical infarct cavities were not different from patients without these cavities. Cerebellar cortical infarct cavities are seen on MRI in as much as one third of patients with recently symptomatic vertebral artery stenosis. Since patients usually have no prior history of vertebrobasilar TIA or stroke, cerebellar cortical infarct cavities should be added to the spectrum of common incidental brain infarcts visible on routine MRI.

    The cerebellum, like the cerebrum, includes a nuclear structure and an overlying cortical structure. Experiments in the past decade have expanded knowledge beyond the traditional function of the cerebellum to include critical roles in motor learning and memory and sensory discrimination. The initial steps in cerebellar development depend on inductive signaling involving FGF and Wnt proteins produced at the mesencephalic/metencephalic boundary. To address the issue of how individual cerebellar cell fates within the cerebellar territory are specified, we examined the expression of transcription factors, including mammalian homologues of LIM homeodomain-containing proteins, basic helix-loop-helix proteins, and three amino acid loop-containing proteins. The results of these studies show that combinatorial codes of transcription factors define precursors of the cerebellar nuclei, and both Purkinje cells and granule neurons of the cerebellar cortex. Examination of gene expression patterns in several hundred lines of Egfp-BAC (bacterial artificial chromosome) transgenic mice in the GENSAT Project revealed numerous genes with restricted expression in cerebellar progenitor populations, including genes specific for cerebellar nuclear precursors and Purkinje cell precursors. In addition, we identified patterns of gene expression that link granule and Purkinje cells to their precerebellar nuclei. These results identify molecular pathways that offer new insights on the development of the nuclear and cortical structures of the cerebellum, as well as components of the cerebellar circuitry.

    Cerebellar patients have been found to show deficits in visual motion discrimination, suggesting that the cerebellum may play a role in visual sensory processing beyond mediating motor control. Here we show that triple-pulse online transcranial magnetic stimulation (TMS) over cerebellar vermis but not over the cerebellar hemispheres significantly impaired motion discrimination. Critically, the interference caused by vermis TMS on motion discrimination did not depend on an indirect effect of TMS over nearby visual areas, as demonstrated by a control experiment in which TMS over V1 but not over cerebellar vermis significantly impaired orientation discrimination. These findings demonstrate the causal role of the cerebellar vermis in visual motion processing in neurologically normal participants.

    Following the recognition of its role in sensory-motor coordination and learning, the cerebellum has been involved in cognitive, emotional, and even personality domains. This study investigated the relationships between cerebellar macro- and micro-structural variations and temperamental traits measured by Temperament and Character Inventory (TCI). High resolution T1-weighted, and Diffusion Tensor Images of 100 healthy subjects aged 18-59 years were acquired by 3 Tesla Magnetic Resonance scanner. In multiple regression analyses, cerebellar Gray Matter (GM) or White Matter (WM) volumes, GM Mean Diffusivity (MD), and WM Fractional Anisotropy (FA) were used as dependent variables, TCI scores as regressors, gender, age, and education years as covariates. Novelty Seeking scores were associated positively with the cerebellar GM volumes and FA, and negatively with MD. No significant association between Harm Avoidance, Reward Dependence or Persistence scores and cerebellar structural measures was found. The present data put toward a cerebellar involvement in the management of novelty.

    2011-01-01

    Viral hemorrhagic fevers (VHFs) caused by arenaviruses belong to the most devastating emerging human diseases and represent serious public health problems. Arenavirus VHFs in humans are acute diseases characterized by fever and, in severe cases, different degrees of hemorrhages associated with a shock syndrome in the terminal stage. Over the past years, much has been learned about the pathogenesis of arenaviruses at the cellular level, in particular their ability to subvert the host cell's innate antiviral defenses. Clinical studies and novel animal models have provided important new information about the interaction of hemorrhagic arenaviruses with the host's adaptive immune system, in particular virus-induced immunosuppression, and have provided the first hints towards an understanding of the terminal hemorrhagic shock syndrome. The scope of this article is to review our current knowledge on arenavirus VHF pathogenesis with an emphasis on recent developments.

    Full Text Available Subarachnoid hemorrhage (SAH is one of the major cause of mortality for stroke. The leading cause is the rupture of an intracrnial aneurym. Acute aneurysmal subarachnoid hemorrhage (SAH is a complex multifaceted disorder that plays out over days to weeks. The development of aneurysms is mainly due to a hemodynamic stress. Considerableadvances have been made in endovascular techniques, diagnostic methods, and surgical and perioperative management guidelines. Rebleeding remains the most imminent danger until the aneurysm is excluded from cerebral circulation. The only effective prevention of rebleeding is repair the aneurysm; choosing the right way with surgical or an endovascular approach. Outcome for patients with SAH remains poor, with population-based mortality rates as high as 45% and significant morbidity among survivors. In this work we analyzed the diagnostic-therapeutic course of patients presenting SAH. We analyzed the types and the occurrence of complications. We present two cases report to better demonstrate that treatments for specific patients need to be individualized.

Her condition rapidly deteriorated into a coma with decorticate and then decerebrate posture, and she died 3 weeks later. There was evidence of extensive intracranial venous sinus thrombosis (ICVST), renal vein thrombosis (RVT), and multiple cerebral hemorrhagic infarcts due to a hypercoagulable state complicating AIDS-associated nephrotic syndrome. This is the first reported case of fatal ICVST and RVT with extensive cerebral hemorrhagic infarcts complicating nephrotic syndrome in a patient with AIDS.

    Cerebral vasospasm (CVS) is a common and severe complication of aneurysmal subarachnoid hemorrhage (aSAH). Despite the improvement in treatment of aSAH, CVS complicating aSAH has remained the main cause of death. CVS begins most often on the third day after the ictal event and reaches the maximum on the 5th–7th postictal days. Several therapeutic modalities have been employed to prevent or reverse CVS. The aim of this review is to summate all the available drug treatment modalities for vasospasm.

    This paper aims to review current literature on the treatment of acute intraventricular hemorrhage in adults with intraventricular infusion of fibrinolytic agents. A literature search on the topics of "intraventricular hemorrhage" or "intracerebral hemorrhage" with "thrombolytic therapy", "fibrinolytic therapy", "urokinase", "streptokinase", "tissue plasminogen activator" or "tPA" covering the years 1966-1997 was carried out electronically. This was supplemented by searching the reference lists of the identified articles. Articles regarding exclusively intracerebral hemorrhage or hematoma, neonatal intraventricular hemorrhage, non-therapeutic issues, and laboratory research were excluded. The included articles are summarized in evidence and evaluation tables. Six articles evaluating the treatment of intraventricular hemorrhage in adults with intraventricular fibrinolytic agents were identified. One reports a small randomized clinical trial including 16 patients and appears to show a statistically insignificant preference for urokinase treatment. Five other reports present case series for which a total of 58 patients were exposed to either streptokinase, urokinase, or recombinant tissue plasminogen activator (rt-PA) and suggest good outcome. Two of them were with non-randomized retrospective or prospective controls, and three have no controls. Despite important limitations, all reports suggest that blood is more rapidly cleared from the ventricles and outcome is better when administering a fibrinolytic agent intraventricularly. While the experience presented in these papers suggests that intraventricular administration of fibrinolytic agents may be associated with fewer complications, more rapid clearing of blood from the ventricles, less late hydrocephalus, and better long-term outcome than is seen in patients treated with ventricular drainage alone, it is insufficient to recommend such treatment as a matter of policy. Substantial methodologic flaws render these

    Full Text Available Bilateral adrenal hemorrhage (BAH is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

    Subarachnoid hemorrhage (SAH) is an important cause of stroke mortality and morbidity, especially in the young stroke population. Recent evidences indicate that neuroinflammation plays a critical role in both early brain injury and the delayed brain deterioration after SAH, including cellular and molecular components. Cerebral vasospasm (CV) can lead to death after SAH and independently correlated with poor outcome. Neuroinflammation is evidenced to contribute to the etiology of vasospasm. Besides, systemic inflammatory response syndrome (SIRS) commonly occurs in the SAH patients, with the presence of non-infectious fever and systematic complications. In this review, we summarize the evidences that indicate the prominent role of inflammation in the pathophysiology of SAH. That may provide the potential implications on diagnostic and therapeutic strategies.

    Disseminated intravascular coagulation (DIC) is a life-threatening complication, and its control is essential for therapeutic success. Recombinant human soluble thrombomodulin alfa (rTM) is a novel therapeutic agent for DIC. The efficacy of rTM in the treatment of DIC is reportedly superior to that of conventional anti-DIC treatments, such as unfractionated heparin or low molecular weight heparin, but hemorrhagic events occasionally interfere with the therapeutic benefits of rTM. We assessed the clinical features of 20 consecutive patients who were given rTM for DIC associated with various hematologic disorders. Eight patients achieved remission of both primary disease and DIC, eight died due to progression of the primary disease, and four died of various hemorrhagic complications. Assessment of 16 biomarkers for coagulation showed that the four patients who died of hemorrhagic complications despite remission of their primary disease showed lower ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin Type 1 motif, member 13) plasma activity than other patients (P = 0.016). The optimal cut-off level of ADAMTS-13 for predicting risk of hemorrhagic complications was 42 % (P = 0.007). Plasma ADAMTS-13 activity determined at diagnosis of DIC may help predict the risk of hemorrhagic events during and/or following DIC treatment with hematologic disorders.

  15. Vestibular and cerebellar contribution to gaze optimality.

    Patients with chronic bilateral vestibular loss have large gaze variability and experience disturbing oscillopsia, which impacts physical and social functioning, and quality of life. Gaze variability and oscillopsia in these patients are attributed to a deficient vestibulo-ocular reflex, i.e. impaired online feedback motor control. Here, we assessed whether the lack of vestibular input also affects feed-forward motor learning, i.e. the ability to choose optimal movement parameters that minimize variability during active movements such as combined eye-head gaze shifts. A failure to learn from practice and reshape feed-forward motor commands in response to sensory error signals to achieve appropriate movements has been proposed to explain dysmetric gaze shifts in patients with cerebellar ataxia. We, therefore, assessed the differential roles of both sensory vestibular information and the cerebellum in choosing optimal movement kinematics. We have previously shown that, in the course of several gaze shifts, healthy subjects adjust the motor command to minimize endpoint variability also when movements are experimentally altered by an increase in the head moment of inertia. Here, we increased the head inertia in five patients with chronic complete bilateral vestibular loss (aged 45.4±7.1 years, mean±standard deviation), nine patients with cerebellar ataxia (aged 56.7±12.6 years), and 10 healthy control subjects (aged 39.7±6.3 years) while they performed large (75° and 80°) horizontal gaze shifts towards briefly flashed targets in darkness and, using our previous optimal control model, compared their gaze shift parameters to the expected optimal movements with increased head inertia. Patients with chronic bilateral vestibular loss failed to update any of the gaze shift parameters to the new optimum with increased head inertia. Consequently, they displayed highly variable, suboptimal gaze shifts. Patients with cerebellar ataxia updated some movement parameters to

    Background and Purpose The location of intracerebral hemorrhage (ICH) is currently described in a qualitative way; we provide a quantitative framework for estimating ICH engagement and its relevance to stroke outcomes. Methods We analyzed 111 patients with ICH from the MISTIE II clinical trial. We estimated ICH engagement at a population level using image registration of CT scans to a template and a previously labeled atlas. Predictive regions of NIHSS and GCS stroke severity scores, collected at enrollment, were estimated. Results The percent coverage of the ICH by these regions strongly outperformed the reader-labeled locations. The adjusted R2 almost doubled from 0.129 (reader-labeled model) to 0.254 (quantitative-location model) for NIHSS and more than tripled from 0.069 (reader-labeled model) to 0.214 (quantitative-location model). A permutation test confirmed that the new predictive regions are more predictive than chance: p<.001 for NIHSS and p<.01 for GCS. Conclusions Objective measures of ICH location and engagement using advanced CT imaging processing provide finer, objective, and more quantitative anatomic information than that provided by human readers.

    Full Text Available Cocaine and its alkaloid free base “crack-cocaine” have long since been substances of abuse. Drug abuse of cocaine via oral, inhalation, intravenous, and intranasal intake has famously been associated with a number of medical complications. Intestinal ischemia and perforation remain the most common manifestations of cocaine associated gastrointestinal disease and have historically been associated with oral intake of cocaine. Here we find a rare case of two relatively uncommon gastrointestinal complications of hemorrhage and pancreatitis presenting within a single admission in a chronic crack cocaine abuser.

  19. Contribution of cerebellar sensorimotor adaptation to hippocampal spatial memory.

    Directory of Open Access Journals (Sweden)

    Jean-Baptiste Passot

    Full Text Available Complementing its primary role in motor control, cerebellar learning has also a bottom-up influence on cognitive functions, where high-level representations build up from elementary sensorimotor memories. In this paper we examine the cerebellar contribution to both procedural and declarative components of spatial cognition. To do so, we model a functional interplay between the cerebellum and the hippocampal formation during goal-oriented navigation. We reinterpret and complete existing genetic behavioural observations by means of quantitative accounts that cross-link synaptic plasticity mechanisms, single cell and population coding properties, and behavioural responses. In contrast to earlier hypotheses positing only a purely procedural impact of cerebellar adaptation deficits, our results suggest a cerebellar involvement in high-level aspects of behaviour. In particular, we propose that cerebellar learning mechanisms may influence hippocampal place fields, by contributing to the path integration process. Our simulations predict differences in place-cell discharge properties between normal mice and L7-PKCI mutant mice lacking long-term depression at cerebellar parallel fibre-Purkinje cell synapses. On the behavioural level, these results suggest that, by influencing the accuracy of hippocampal spatial codes, cerebellar deficits may impact the exploration-exploitation balance during spatial navigation.

    Gastrointestinal (GI) bleeding refers to any hemorrhage ascribed to the pathologies of the gastrointestinal tract, extending from the mouth to the anal canal. Despite the recent improvements in the endoscopic, hemostatic and adjuvant pharmacologic techniques, the reported mortality is still around 5%-10% for peptic ulcer bleeding and about 15%-20% for variceal hemorrhages. Although endoscopic management reduces the rates of re-bleeding, surgery, and mortality in active bleeding; early recurrence ratios still occur in around 20% of the cases even with effective initial hemostatic measures.In this quest for an alternative pro-hemostatic agent for the management of GI bleedings, Ankaferd blood stopper (ABS) offers a successful candidate, specifically for “difficult-to-manage” situations as evidenced by data presented in several studies. ABS is a standardized mixture of the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica. It is effective in both bleeding individuals with normal hemostatic parameters and in patients with deficient primary and/or secondary hemostasis. ABS also modulates the cellular apoptotic responses to hemorrhagic stress, as well as hemostatic hemodynamic activity. Through its effects on the endothelium, blood cells, angiogenesis, cellular proliferation, vascular dynamics, and wound healing, ABS is now becoming an effective alternative hemostatic medicine for gastrointestinal bleedings that are resistant to conventional anti-hemorrhagic measurements. The aim of this review is to outline current literature experience suggesting the place of ABS in the management of GI bleeding, and potential future controlled trials in this complicated field.

    Deficiency of vitamin K predisposes to early, classic or late hemorrhagic disease of the newborn (HDN); of which late HDN may be associated with serious and life-threatening intracranial hemorrhage. Late HDN is characterized intracranial bleeding in infants aged 1 week to 6 months due to severe vitamin K deficiency. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. Children with cholestatic liver disease are at risk for developing secondary vitamin K deficiency because of fat malabsorbtion and inadequate dietary intake. In this study, we described 11 infants with cholestatic liver disease with different etiologies exhibiting intracranial hemorrhage (ICH). Six patients underwent surgical evacuation of ICH, following the administration of vitamin K and/or fresh frozen plasma. The possibility of cholestatic liver disease should be considered in the treatment of ICH due to vitamin K deficiency.

    Classical lissencephaly may be associated with cerebellar hypoplasia and when significant cerebellar abnormalities occur, defects in proteins encoded by TUBA1A, RELN, and very-low-density lipoprotein receptor (VLDLR) genes have been reported. We present a neonate with a severe neurologic phenotype associated with hypotonia, oropharyngeal incoordination that required a gastric tube for feeding, intractable epilepsy, and congenital cataracts. Her brain magnetic resonance imaging (MRI) showed classical lissencephaly, ventriculomegaly, absent corpus callosum, globular and vertical hippocampi, and severe cerebellar and brainstem hypoplasia. She died at 6 weeks of age. No specific molecular diagnosis was made. This likely represents a previously undescribed genetic lissencephaly syndrome.

    In 31 patients with completed stroke (n = 30) or PRIND (n = 1) a brain SPECT with /sup 123/I-labeled amphetamines was performed. In 14 (= 45%) of the respective patients - suffering from long-lasting hemiplegia - crossed cerebellar diaschisis was present. The interval between onset of the disease and time of examination varied between 1 week and 7 years. On the other hand, patients without crossed cerebellar diaschisis did not, with one exception, suffer from hemiplegia. It is likely that this phenomenon is caused by the reduction of spino-cerebellar stimuli due to the paresis of the respective extremities.

    Venous infarction in the cerebellum has been reported only rarely, probably because of the abundant venous collateral drainage in this region. Bilateral occipital infarction is a rare cause of visual loss in cerebral venous thrombosis. We describe a 50-year-old woman with a history of ulcerative colitis who developed acute cerebellar ataxia and cortical blindness. She had bilateral cerebellar and occipital lesions related to sigmoid venous thrombosis and achieved complete recovery with anticoagulation therapy. Cerebral venous thrombosis should be considered in cases of simultaneous cerebellar and occipital vascular lesions.

    Full Text Available A case of choroidal rupture caused by airbag-associated blunt eye trauma and complicated with massive subretinal hemorrhage and vitreous hemorrhage that was successfully treated with intravitreal injection of expansile gas and bevacizumab is presented. A 53-year-old man suffered from loss of vision in his right eye due to blunt eye trauma by a safety airbag after a traffic accident. On initial examination, the patient had no light perception in his right eye. Dilated ophthalmoscopy revealed massive subretinal hemorrhage with macular invasion and faint vitreous hemorrhage. We performed intravitreal injection of pure sulfur hexafluoride twice for displacement, after which visual acuity improved to 0.03. For persistent subretinal hemorrhage and suspicion of choroidal neovascularization (CNV, intravitreal bevacizumab (1.25 mg/0.05 mL injection was administered. After 3 weeks, the visual acuity of his right eye recovered to 0.4. For early-stage choroidal rupture-induced subretinal hemorrhage and complications of suspected CNV, intravitreal injection of expandable gas and intraocular injection of antiangiogenesis drugs seem to be an effective treatment.

    Full Text Available Hereditary ataxia is a heterogeneous disorder characterized by progressive ataxia combined with/without peripheral neuropathy, extrapyramidal symptoms, pyramidal symptoms, seizure, and multiple systematic involvements. More than 35 autosomal dominant cerebellar ataxias have been designated as spinocerebellar ataxia, and there are 55 recessive ataxias that have not been named systematically. Conducting genetic sequencing to confirm a diagnosis is difficult due to the large amount of subtypes with phenotypic overlap. The prevalence of hereditary ataxia can vary among countries, and estimations of prevalence and subtype frequencies are necessary for planning a diagnostic strategy in a specific population. This review covers the various hereditary ataxias reported in the Korean population with a focus on the prevalence and subtype frequencies as the clinical characteristics of the various subtypes.

    Cerebellar mutism and subsequent dysarthria (MSD) is a possible complication of posterior fossa surgery. It is usually seen in children after resection of a cerebellar mass lesion. Most patients become mute after a period of (near)normal postoperative speech, and are dysarthric once speech resumes. The pathophysiological mechanisms underlying MSD are most probably multifactorial, combining neuroanatomical, neurophysiological, neuropsychological, and psychological factors. The aim of the present article is to better define the MSD syndrome. The cerebellum is not only involved in motor control. It is also part of a distributed neural circuitry which underlies higher cognitive functions such as, for instance, those associated with the programming of kinetic parameters before motor initiation of a movement. We hypothesize that it could also be involved in the mental initiation which precedes the programming of any intentional bucco-phonatory movements to be performed in order to express oneself.

    Paraneoplastic cerebellar degeneration is a rare disorder caused likely by autoimmune mechanisms in malignant oncologic diseases, and the most common tumors are ovarian, breast, lung cancer, and m. Hodgkin. An immune reaction is supposed to be directed against identical antigens of cerebellum and tumor, and paraneoplastic antibodies called anti-Yo, anti-Hu, anti-Ri, or anti-Tr are often detected in blood and cerebrospinal fluid. The course of paraneoplastic cerebellar degeneration as a complication of ovarian cancer is described. The relationship between the malignancy and pathologic changes in cerebellum was confirmed by positive immunohistochemical and immunofluorescence reaction between a patient's anti-Yo-positive serum and her own Purkinje's and ovarian cancer cells.

    Abstract Vertebrobasilar dolichoectasia (VBD) is a chronic disorder with various cerebrovascular and compressive manifestations, involving subarachnoid hemorrhage (SAH). Occurrence of SAH shortly after worsening of clinical VBD symptoms has occasionally been reported. The goal of the study was to examine this association, in particular its pathophysiology, clinical precursor signs, time course, and outcome. To this end, in a retrospective multicenter study, we analyzed 20 patients with VBD and SAH in regard to preceding clinical symptoms, presence of vertebrobasilar thrombosis and ischemia, outcome and neuropathological correlates. Median age of the 7 female and 13 male patients was 70 years (interquartile range [IQR] 18.3 years). Fourteen patients (70%) presented with new or acutely worsening posterior fossa signs at a median of 3 days prior to SAH (IQR 2, range 0.5–14). A thrombus within the VBD was detected in 12 patients (60%). Thrombus formation was associated with clinical deterioration (χ2 = 4.38, P = 0.04) and ponto-cerebellar ischemia (χ2 = 8.09, P = 0.005). During follow-up after SAH, 13 patients (65%) died, after a median survival time of 24 hours (IQR 66.2, range 2–264 hours), with a significant association between proven ponto-cerebellar ischemia and case fatality (χ2 = 6.24, P = 0.01). The data establish an association between clinical deterioration in patients with VBD, vertebrobasilar ischemia, and subsequent SAH. Antithrombotic treatment after deterioration appears controversial and SAH outcome is frequently fatal. Our data also indicate a short window of 3 days that may allow for evaluating interventional treatment, preferably within randomized trials. PMID:27399083

    Germinal matrix hemorrhage (GMH) is the most common neurological disease of premature newborns. GMH causes neurological sequelae such as cerebral palsy, post-hemorrhagic hydrocephalus, and mental retardation. Despite this, there is no standardized animal model of spontaneous GMH using newborn rats to depict the condition. We asked whether stereotactic injection of collagenase type VII (0.3 U) into the ganglionic eminence of neonatal rats would reproduce the acute brain injury, gliosis, hydrocephalus, periventricular leukomalacia, and attendant neurological consequences found in humans. To test this hypothesis, we used our neonatal rat model of collagenase-induced GMH in P7 pups, and found that the levels of free-radical adducts (nitrotyrosine and 4-hyroxynonenal), proliferation (mammalian target of rapamycin), inflammation (COX-2), blood components (hemoglobin and thrombin), and gliosis (vitronectin and GFAP) were higher in the forebrain of GMH pups, than in controls. Neurobehavioral testing showed that pups with GMH had developmental delay, and the juvenile animals had significant cognitive and motor disability, suggesting clinical relevance of the model. There was also evidence of white-matter reduction, ventricular dilation, and brain atrophy in the GMH animals. This study highlights an instructive animal model of the neurological consequences after germinal matrix hemorrhage, with evidence of brain injuries that can be used to evaluate strategies in the prevention and treatment of post-hemorrhagic complications.

    The aim of the current study was to compare postural responses to repetitive platform-evoked perturbations in cerebellar patients with those of healthy subjects using a classical conditioning paradigm. The perturbations consisted of tilting of the platform (unconditioned stimulus: US) at random time intervals, preceded by an auditory signal that represented the conditioning stimulus (CS). Physiological reactions were recorded biomechanically by measuring the vertical ground forces, yielding the center of vertical pressure (CVP), and electrophysiologically by EMG measurements of the main muscle groups of both legs. The recording session consisted of a control section with US-alone trials, a testing section with paired stimuli and a brief final section with US-alone trials. Healthy control subjects were divided into those establishing conditioned responses (CR) in all muscles tested (strategy I) and those with CR in the gastrocnemius muscles only (strategy II), suggesting an associative motor-related process is involved. Patients with a diffuse, non-localized disease were almost unable to establish CR. This was also true for a patient with a focal surgical lesion with no CR on the affected side but who, simultaneously, showed an essentially normal CR incidence on the intact side. During US-alone trials healthy controls exhibited a remarkable decay of the UR amplitude due to a non-associative motor-related process such as habituation. The decay was most prominent in the paired trials section. In contrast, patients showed no significant differences in the UR amplitude throughout the entire recording session. Analysis of the CVP supported the electrophysiological findings, showing CR in the controls only. The differences between the responses of control subjects and those of the cerebellar patients imply strongly that the cerebellum is involved critically in controlling associative and non-associative motor-related processes.

  13. Spontaneous Atraumatic Mediastinal Hemorrhage

    Full Text Available Spontaneous atraumatic mediastinal hematomas are rare. We present a case of a previously fit and well middle-aged lady who presented with acute breathlessness and an increasing neck swelling and spontaneous neck bruising. On plain chest radiograph, widening of the mediastinum was noted. The bruising was later confirmed to be secondary to mediastinal hematoma. This life-threatening diagnostic conundrum was managed conservatively with a multidisciplinary team approach involving upper gastrointestinal and thoracic surgeons, gastroenterologists, radiologists, intensivists, and hematologists along with a variety of diagnostic modalities. A review of literature is also presented to help surgeons manage such challenging and complicated cases.

    Vascular cognitive impairment and vascular dementia are composed of cognitive deficits resulted from a range of vascular lesions and pathologies, including both ischemic and hemorrhagic. However the contribution of spontaneous intracerebral hemorrhage presumed due to small vessel diseases on cognitive impairment is underestimated, in contrast to the numerous studies about the role of ischemic vascular disorders on cognition. In this review we summarize recent findings from clinical studies and appropriate basic science research to better elucidate the role and possible mechanisms of intracerebral hemorrhage in cognitive impairment and dementia. This article is part of a Special Issue entitled: Vascular Contributions to Cognitive Impairment and Dementia edited by M. Paul Murphy, Roderick A. Corriveau and Donna M. Wilcock.

    2015-11-01

    The ventriculoperitoneal (VP) shunt is a routine procedure for cerebrospinal fluid (CSF) diversion, and is associated with many complications. A delayed hemorrhage after the VP shunt surgery, however, is quite rare. In this study, we report a case involving late-onset hemorrhage. The 67-year-old male patient with a history of head trauma and brain surgery underwent a VP shunt placement for hydrocephalus. The surgery course was uneventful and no bleeding was revealed in the first computed tomographic (CT) scan after the procedure. However, a massive intraparenchymal and intraventricular hemorrhage occurred 8 h following adjustment of the valve system on the 8th day after surgery.Erosion of the vasculature by catheter cannulation and a sudden reduction of CSF pressure after downregulation of the valve could be one of the possible causes of the intracerebral hemorrhage (ICH).

    This manuscript reports Bacillus cereus sepsis in two cases with acute myelogenous leukemia (AML) who suffered complications of fatal intracranial hemorrhage during remission induction therapy. The first case was 43-year-old male with AML (M0) receiving first consolidation chemotherapy who developed sudden diarrhea, abdominal pain and spiking fever. Two days later, he died of intracranial hemorrhage. The second case was 15-year-old male with AML (M5b) who was receiving first induction chemotherapy. He developed headache and vomiting following spiking fever and diarrhea. He died of subarachnoid hemorrhage the next day. In both cases, Bacillus cereus was isolated from blood culture. Fatal intracranial hemorrhage due to severe bleeding tendency caused rapid to death in both cases. These bleeding tendencies might have been induced by B. cereus sepsis. In addition, we should not overlook B. cereus as contamination, but rather consider it as a potential pathogen, when isolated from blood culture.

    @@ Massive presacral venous hemorrhage is a non-pulsatile hemorrhage due to the rupture of either the presacral venous plexus or the sacral vertebral basivertebral vein. It is a serious complication of surgery for pelvic tumors, like middle or low segment rectal cancers, advanced ovarian cancers and presacral tumors. Massive presacral venous hemorrhage is dangerous and difficult to manage. Traditional methods for controlling this condition include packing with laparotomy pads, the use of sterile thumbtacks,1 ligation of the internal iliac vessel,2 and selective arterial embolization.3 These methods are generally ineffective. Recently, several other methods for controlling presacral bleeding have been reported, such as occlusion of the wound with rectus muscle fragment welding,4 oppression with sterile normal saline bags,5 balloon tamponade,6 and the use of endoscopic staples.7 However, these measures fail to arrest the bleeding in some patients, resulting in massive hemorrhage and even death.

    Sheehan's syndrome is described as panhypopituitarism secondary to a pituitary hypoperfusion during or just after obstetric hemorrhage. Advances in obstetric care make this syndrome quite unusual, but some cases are reported in underdeveloped countries. Clinical presentation may change depending on the severity of the hormone deficiencies. The diagnosis is clinical, but abnormalities are observed in the magnetic resonance in up to 70% of patients. We present a case of a woman with hypotension, hypothermia and edemas in relation to a previous massive postpartum hemorrhage. Failure in lactation was the clue to the diagnosis. A review of its main features, its diagnosis and treatment in the current literature is also presented.

    Full Text Available Cerebellar glioblastoma multiforme (GBM is a rare tumor that accounts for only 1% of all cases of GBM and its giant cell variant is even much rarely encountered in adults. A case of cerebellar giant cell GBM managed at our institution reporting its clinical presentation, radiological and histological findings, and treatment instituted is described. In conjunction, a literature review, including particular issues, clinical data, advances in imaging studies, pathological characteristics, treatment options, and the behavior of such malignant tumor is presented. It is very important for the neurosurgeon to make the differential diagnosis between the cerebellar GBM, and other diseases such as metastasis, anaplastic astrocytomas, and cerebellar infarct because their treatment modalities, prognosis, and outcome are different.

  3. Anomalous cerebellar anatomy in Chinese children with dyslexia

    2016-03-01

    Full Text Available The cerebellar deficit hypothesis for developmental dyslexia (DD claims that cerebellar dysfunction causes the failures in the acquisition of visuomotor skills and automatic reading and writing skills. In people with dyslexia in the alphabetic languages, the abnormal activation and structure of the right or bilateral cerebellar lobes have been identified. Using a typical implicit motor learning task, however, one neuroimaging study demonstrated the left cerebellar dysfunction in Chinese children with dyslexia. In the present study, using voxel-based morphometry, we found decreased gray matter volume in the left cerebellum in Chinese children with dyslexia relative to age-matched controls. The positive correlation between reading performance and regional gray matter volume suggests that the abnormal structure in the left cerebellum is responsible for reading disability in Chinese children with dyslexia.

    We looked at regional cerebellar blood flow in patients with Minamata disease (MD) using technetium-99 m ethyl cysteinate dimer (99m-Tc-ECD). We carried out single-photon emission computed tomography (SPECT) on 15 patients with MD (eight men, seven women, aged 51-78 years, mean 70.5 years) and 11 control subjects (eight men, three women, aged 62-80 years, mean 72.5 years). Regional blood flow was measured in the superior, middle, and inferior portions of the cerebellar hemispheres, and the frontal, temporal and occipital cerebral lobes. The degree of cerebellar atrophy was assessed on MRI. There were significant differences in regional blood flow in all parts of the cerebellum between patients and control, but no significant decrease was observed in the cerebrum. Blood flow was lower in the inferior cerebellum than in the other parts. Even in patients without cerebellar atrophy, flow was significantly decreased regional blood flow in the inferior part.

    Neuroimages of tentorial hemorrhage associated with vacuum extraction have been rarely reported. The authors present the case of a 5-day-old newborn with this entity. CT showed retrocerebellar hemorrhage and MRI demonstrated tentorial hemorrhage extending inferiorly over the cerebellum and superiorly over the occipital regions. We believe that these imaging modalities are helpful in delineating the extent of the hemorrhage and assessing the prognosis. (orig.)

    The number of neuroendovascular treatments of both ruptured and unruptured aneurysms has increased substantially in the last two decades. Complications of endovascular treatments of cerebral aneurysms are rare but can potentially lead to acute worsening of the neurological status, to new neurological deficits or death. Some of the possible complications, such as vascular access site complications or systemic side effects associated with contrast medium (e.g. contrast medium allergy, contrast induced nephropathy) can also be encountered in diagnostic angiography. The most common complications of endovascular treatment of cerebral aneurysms are related to acute thromboembolic events and perforation of the aneurysm. Overall, the reported rate of thromboembolic complications ranges between 4.7% and 12.5% while the rate of intraprocedural rupture of cerebral aneurysms is about 0.7% in patients with unruptured aneurysms and about 4.1% in patients with previously ruptured aneurysms. Thromboembolic and hemorrhagic complications may occur during different phases of endovascular procedures and are related to different technical, clinical and anatomic reasons. A thorough knowledge of the different aspects of these complications can reduce the risk of their occurrence and minimize their clinical sequelae. A deep understanding of complications and of their management is thus part of the best standard of care.

    The clinical and neuropathologic findings of 55 adults and 30 children who received liver transplants were reviewed. Encephalopathy was the most common clinical neurologic syndrome and was usually caused by metabolic or anoxic causes. (Alzheimer type astrocytes were present in 73 per cent of patients, and evidence of diffuse hypoxic damage was present in 40 per cent of children and 25 per cent of adults.) Cerebrovascular lesions were a common finding with infarcts or hemorrhages present in 30 per cent of patients. CNS infections were documented in 34 per cent of patients. Seizures were present in a third of patients. Central pontine myelinolysis was present in 12 per cent of patients and was more common in adults than in children. Antemortem diagnosis of neurologic complications was more often based on clinical presentation rather than specific radiologic or laboratory tests.

    2008-01-01

    Full Text Available It has been suggested that oxidative stress and/or mercury compounds play an important role in the pathophysiology of autism. This study compared for the first time the cerebellar levels of the oxidative stress marker 3-nitrotyrosine (3-NT, mercury (Hg and the antioxidant selenium (Se levels between control and autistic subjects. Tissue homogenates were prepared in the presence of protease inhibitors from the frozen cerebellar tissue of control (n=10; mean age, 15.5 years; mean PMI, 15.5 hours and autistic (n=9; mean age 12.1 years; mean PMI, 19.3 hours subjects. The concentration of cerebellar 3-NT, determined by ELISA, in controls ranged from 13.69 to 49.04 pmol g-1 of tissue; the concentration of 3-NT in autistic cases ranged from 3.91 to 333.03 pmol g-1 of tissue. Mean cerebellar 3-NT was elevated in autism by 68.9% and the increase was statistically significant (p=0.045. Cerebellar Hg, measured by atomic absorption spectrometry ranged from 0.9 to 35 pmol g-1 tissue in controls (n=10 and from 3.2 to 80.7 pmol g-1 tissue in autistic cases (n=9; the 68.2% increase in cerebellar Hg was not statistically significant. However, there was a positive correlation between cerebellar 3-NT and Hg levels (r=0.7961, p=0.0001. A small decrease in cerebellar Se levels in autism, measured by atomic absorption spectroscopy, was not statistically significant but was accompanied by a 42.9% reduction in the molar ratio of Se to Hg in the autistic cerebellum. While preliminary, the results of the present study add elevated oxidative stress markers in brain to the growing body of data reflecting greater oxidative stress in autism.

    Weeks, Heidi M; Therrien, Amanda S; Bastian, Amy J

    2017-04-01

    It has been hypothesized that an important function of the cerebellum is predicting the state of the body during movement. Yet, the extent of cerebellar involvement in perception of limb state (i.e., proprioception, specifically limb position sense) has yet to be determined. Here, we investigated whether patients with cerebellar damage have deficits when trying to locate their hand in space (i.e., proprioceptive localization), which is highly important for everyday movements. By comparing performance during passive robot-controlled and active self-made multi-joint movements, we were able to determine that some cerebellar patients show improved precision during active movement (i.e., active benefit), comparable to controls, whereas other patients have reduced active benefit. Importantly, the differences in patient performance are not explained by patient diagnosis or clinical ratings of impairment. Furthermore, a subsequent experiment confirmed that active deficits in proprioceptive localization occur during both single-joint and multi-joint movements. As such, it is unlikely that localization deficits can be explained by the multi-joint coordination deficits occurring after cerebellar damage. Our results suggest that cerebellar damage may cause varied impairments to different elements of proprioceptive sense. It follows that proprioceptive localization should be adequately accounted for in clinical testing and rehabilitation of people with cerebellar damage.

    Interrelations between the cerebellar function and cerebellar atrophy were studied in the cases with Minamata disease and spinocerebellar degeneration and in the healthy subjects. For evaluation of the cerebellar function, the statokinesigraph (SKG) was recorded and the shifting length (L-SKG) and moving area (A-SKG) of postural sway were obtained using body balance analyzer. Cerebellar atrophy was evaluated by the rostrocaudal and ventrodorsal diameters of whole vermis and the total area of upper and lower parts (area-UL) of vermis on the midsagittal plane of MR imaging. It was disclosed that there was significant correlation between the L-SKG and the measurement of rostrocaudal diameter as well as the area-UL of vermis through the patients with Minamata disease and the healthy subjects. When added the patients with spinocerebellar degeneration, the significant correlation was not obtainable probably because of the progressive processes of the disease. (author).

    Full Text Available Hyponatremia is the most frequently encountered electrolyte abnormality in critically ill patients. Hyponatremia on admission has been identified as an independent predictor of in-hospital mortality in patients with spontaneous intracerebral hemorrhage (sICH. However, the incidence and etiology of hyponatremia (HN during hospitalization in a neurointensive care unit following spontaneous intracerebral hemorrhage (sICH remains unknown. This was a retrospective analysis of consecutive patients admitted to Detroit Receiving Hospital for sICH between January 2006 and July 2009. All serum Na levels were recorded for patients during the ICU stay. HN was defined as Na <135 mmol/L. A total of 99 patients were analyzed with HN developing in 24% of sICH patients. Patients with HN had an average sodium nadir of 130 ± 3 mmol/L and an average time from admission to sodium <135 mmol/L of 3.9 ± 5.7 days. The most common cause of hyponatremia was syndrome of inappropriate antidiuretic hormone (90% of HN patients. Patients with HN were more likely to have fever (50% vs. 23%; p = 0.01, infection (58% vs. 28%; p = 0.007 as well as a longer hospital length of stay (14 (8–25 vs. 6 (3–9 days; p < 0.001. Of the patients who developed HN, fifteen (62.5% patients developed HN in the first week following sICH. This shows HN has a fairly high incidence following sICH. The presence of HN is associated with longer hospital length of stays and higher rates of patient complications, which may result in worse patient outcomes. Further study is necessary to characterize the clinical relevance and treatment of HN in this population.

    Sometimes in the course of care in a neonatal intensive care unit, there may be a rush to intervene in cases where limited intervention is actually the correct course. One such example is that of neonatal adrenal hemorrhage. We present the case of a male term neonate with shock, metabolic acidosis, distended abdomen, and falling hematocrit. His prenatal and delivery histories were uneventful except for a nuchal cord. Apgar scores were 9 and 9. Because of his dramatic presentation, certain members of the medical team suggested immediate surgical intervention. However, a calm and careful evaluation revealed the true diagnosis and course of action. Ultrasound of the abdomen showed a mass between the liver and kidney, but the origin was difficult to identify. A computed tomography scan supported the diagnosis of right adrenal hemorrhage. His serum cortisol level was normal. The patient was managed conservatively and discharged home after a 1-week stay in the hospital. Subsequent abdominal ultrasound showed resolving adrenal hemorrhage with minimal calcification. A review of the pertinent literature is presented. Physicians should remember adrenal hemorrhage when evaluating a newborn infant with shock, acidosis, abdominal distention, and falling hematocrit and that conservative management is usually indicated.

DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study and laboratory investigations at a center for autoimmune neurologic disorders among 34 patients with CA and GAD65-Abs, including 25 with long-term follow-up data (median, 5.4 years; interquartile range, 3.1-10.3 years). MAIN OUTCOMES AND MEASURES Analysis of clinicoimmunologic features and predictors of response to immunotherapy. Immunochemistry on rat brain, cultured neurons, and human embryonic kidney cells expressing GAD65, GAD67, α1-subunit of the glycine receptor, and a repertoire of known cell surface autoantigens were used to identify additional antibodies. Twenty-eight patients with stiff person syndrome and GAD65-Abs served as controls. RESULTS The median age of patients was 58 years (range, 33-80 years); 28 of 34 patients (82%) were women. Nine patients (26%) reported episodes of brainstem and cerebellar dysfunction or persistent vertigo several months before developing CA. The clinical presentation was subacute during a period of weeks in 13 patients (38%). Nine patients (26%) had coexisting stiff person syndrome symptoms. Systemic organ-specific autoimmunities (type 1 diabetes mellitus and others) were present in 29 patients (85%). Twenty of 25 patients with long-term follow-up data received immunotherapy (intravenous immunoglobulin in 10 and corticosteroids and intravenous immunoglobulin or other immunosuppressors in 10), and 7 of them (35%) improved. Predictors of clinical response included subacute onset of CA (odds ratio [OR], 0.50; 95% CI, 0.25-0.99; P = .047) and prompt immunotherapy (OR, 0.98; 95% CI, 0.96-0.99; P = .01). Similar

    Full Text Available Spontaneous cerebral hemorrhage or intracranial hemorrhage accounts for 10-15% of all strokes. Intracranial hemorrhage is much less common than ischemic stroke, but has higher mortality and morbidity, one of the leading causes of severe disability. Various alterations, among these the endocrine were identified when an intracerebral hemorrhage, these stress-mediated mechanisms exacerbate secondary injury. Deep knowledge of the injuries which are directly involved alterations of glucose, offers insight as cytotoxicity, neuronal death and metabolic dysregulations alter the prognosis of patients with spontaneous intracerebral hemorrhage.

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    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.

    This protocol describes methods for recording synaptically evoked Ca(2+) waves from individual Bergmann glia (BG) in slices of cerebellar cortex. Unlike protoplasmic, star-shaped astrocytes, whose thin processes pose a serious challenge to stable Ca(2+) measurements, BG are large radial cells, with several main processes that run over distances of several hundred micrometers toward the pia and ensheathe thousands of parallel fiber (PF) synapses. Stimulation of PF synapses with brief bursts can trigger long-lasting Ca(2+) responses in BG processes, which can be reliably recorded using a cooled charge-coupled device (CCD) camera. This protocol was developed to enable measurements of Ca(2+) waves in individual BG loaded with a high-affinity Ca(2+) indicator such as Fura-2 for up to 2 h. Because BG recorded in slices rarely display spontaneous (i.e., tetrodotoxin [TTX]-sensitive) or intrinsic Ca(2+) transients, Ca(2+) waves can be evoked repeatedly and reliably, which permits quantitative studies using pharmacological tools. Fluorescence measurements obtained using CCD technology offer a straightforward means of characterizing the mechanisms and potential functional consequences of widespread and long-lasting, store-mediated Ca(2+) increases in astrocytes.

  11. Electrophysiological mapping of novel prefrontal - cerebellar pathways

    Full Text Available Whilst the cerebellum is predominantly considered a sensorimotor control structure, accumulating evidence suggests that it may also subserve non motor functions during cognition. However, this possibility is not universally accepted, not least because the nature and pattern of links between higher cortical structures and the cerebellum are poorly characterized. We have therefore used in vivo electrophysiological methods in anaesthetized rats to directly investigate connectivity between the medial prefrontal cortex (prelimbic subdivision, PrL and the cerebellum. Stimulation of deep layers of PrL evoked distinct field potentials in the cerebellar cortex with a mean latency to peak of approximately 35ms. These responses showed a well-defined topography, and were maximal in lobule VII of the contralateral vermis (a known oculomotor centre; they were not attenuated by local anesthesia of the overlying M2 motor cortex, though M2 stimulation did evoke field potentials in lobule VII with a shorter latency. Single-unit recordings showed that prelimbic cortical stimulation elicits complex spikes in lobule VII Purkinje cells, indicating transmission via a previously undescribed cerebro-olivocerebellar pathway. Our results therefore establish a physiological basis for communication between PrL and the cerebellum. The role(s of this pathway remain to be resolved, but presumably relate to control of eye movements and/or distributed networks associated with integrated prefrontal cortical functions.

    Stopping during walking, a dynamic motor task frequent in everyday life, is very challenging for ataxic patients, as it reduces their gait stability and increases the incidence of falls. This study was conducted to analyse the biomechanical characteristics of upper and lower body segments during abrupt stopping in ataxic patients in order to identify possible strategies used to counteract the instability in the sagittal and frontal plane. Twelve patients with primary degenerative cerebellar ataxia and 12 age- and sex-matched healthy subjects were studied. Time-distance parameters, dynamic stability of the centre of mass, upper body measures and lower joint kinematic and kinetic parameters were analysed. The results indicate that ataxic patients have a great difficulty in stopping abruptly during walking and adopt a multi-step stopping strategy, occasionally with feet parallel, to compensate for their inability to coordinate the upper body and to generate a well-coordinated lower limb joint flexor-extensor pattern and appropriate braking forces for progressively decelerating the progression of the body in the sagittal plane. A specific rehabilitation treatment designed to improve the ability of ataxic patients to transform unplanned stopping into planned stopping, to coordinate upper body and to execute an effective flexion-extension pattern of the hip and knee joints may be useful in these patients in order to improve their stopping performance and prevent falls.

    Congenital rubella infection has been associated with a number of abnormalities including cardiac, central nervous system and placental complications. We present a case with multiple fetal abnormalities detected on prenatal ultrasound, and confirmed postnatally, that included a single umbilical artery, severe tricuspid regurgitation, micrognathia and agenesis of the inferior cerebellar vermis. Postnatal echocardiography additionally revealed unobstructed total anomalous pulmonary venous drainage (TAPVD) into the coronary sinus. Placental examination showed signs of placentitis, and polymerase chain reaction on neonatal serum was positive for rubella. Following a multidisciplinary team review, it was decided to provide only supportive care, and the infant died at 6 months of age owing to a respiratory tract infection. To our knowledge, TAPVD and agenesis of the inferior cerebellar vermis have not been reported previously in association with congenital rubella infection. This case illustrates how congenital infection may present in atypical ways and stresses the importance of considering congenital infection in the differential diagnosis of fetal anomalies when multiple features are present.

    The cerebellum is an important target of ethanol toxicity given that cerebellar ataxia is the most consistent physical manifestation of acute ethanol consumption. Despite the significance of the cerebellum in ethanol-induced cerebellar ataxia (EICA), the cellular and molecular mechanisms underlying EICA are incompletely understood. However, two important findings have shed greater light on this phenomenon. First, ethanol-induced blockade of cerebellar adenosine uptake in rodent models points to a role for adenosinergic A1 modulation of EICA. Second, the consistent observation that intracerebellar administration of nicotine in mice leads to antagonism of EICA provides evidence for a critical role of cerebellar nitric oxide (NO) in EICA reversal. Based on these two important findings, this review discusses the potential molecular events at two key synaptic sites (mossy fiber-granule cell-Golgi cell (MGG synaptic site) and granule cell parallel fiber-Purkinje cell (GPP synaptic site) that lead to EICA. Specifically, ethanol-induced neuronal NOS inhibition at the MGG synaptic site acts as a critical trigger for Golgi cell activation which leads to granule cell deafferentation. Concurrently, ethanol-induced inhibition of adenosine uptake at the GPP synaptic site produces adenosine accumulation which decreases glutamate release and leads to the profound activation of Purkinje cells (PCs). These molecular events at the MGG and GPP synaptic sites are mutually reinforcing and lead to cerebellar dysfunction, decreased excitatory output of deep cerebellar nuclei, and EICA. The critical importance of PCs as the sole output of the cerebellar cortex suggests normalization of PC function could have important therapeutic implications.

    Abnormal cortical volume is well-documented in patients with major depressive disorder (MDD), but cerebellar findings have been heterogeneous. It is unclear whether abnormal cerebellar structure relates to disease state or medication. In this study, using structural MRI, we investigated cerebellar volume in clinically acute (with and without psychotropic treatment) and remitted MDD patients. High-resolution structural MRI data at 3T were obtained from acute medicated (n=29), acute unmedicated (n=14) and remitted patients (n=16). Data from 29 healthy controls were used for comparison purposes. Cerebellar volume was investigated using cerebellum-optimized voxel-based analysis methods. Patients with an acute MDD episode showed increased volume of left cerebellar area IX, and this was true for both medicated and unmedicated individuals (pvolume. In remitted, but not in acutely ill patients, area IX volume was significantly associated with measures of depression severity, as assessed by the Hamilton Depression Rating Scale (HAMD). In addition, area IX volume in remitted patients was significantly related to the duration of antidepressant treatment. In acutely ill patients, no significant relationships were established using clinical variables, such as HAMD, illness or treatment duration and number of depressive episodes. The data suggest that cerebellar area IX, a non-motor region that belongs to a large-scale brain functional network with known relevance to core depressive symptom expression, exhibits abnormal volume in patients independent of clinical severity or medication. Thus, the data imply a possible trait marker of the disorder. However, given bilaterality and an association with clinical scores at least in remitted patients, the current findings raise the possibility that cerebellar volume may be reflective of successful treatment as well.

    Full Text Available Aim. The aim of the study was to describe a case of the patient with cerebellar cognitive affective syndrome CCAS, characterize the role of cerebellum in the regulation of cognitive functions and present theprocedure of neuropsychological diagnosis useful in indicating the specific cognitive and emotional problems in patients with cerebellar damage.Case report. A 41- year old man with an ischemic cerebellar stroke of its right hemisphere manifested the neuropsychological symptoms typical for the frontal damage: euphoric mood, disorganized behavior,lack of criticism and mental plasticity, tendency to shorten the personal distance, problems with mistake correction. In neuropsychological diagnosis we used following methods: Raven Progressive Matrices Test, Mini Mental Stage Examination (MMSE, Trail Making Test, Wisconsin Card Sorting Test, Stroop Interference Test, Word Fluency Test, Auditory Verbal Learning Test by Łuria, Benton Visual Retention Test, Digit Span.Results. Analyzing the obtained results we observed the significant decrease of all executive functions: planning, abstract thinking, cognitive flexibility, adaptation to new situations as well as memory impairments and changes in emotional and behavioral state similar to frontal syndrome. The whole of impairments including the typical cerebellar symptoms (ataxia, dysarthria, dysmetria,hypotonia create the cerebellar cognitive affective syndrome CCAS with leading role of dysexecutive syndrome.Conclusions. The cerebellum takes part in the regulation of cognitive functions. The cerebellar damages can imitate the emotional- cognitive problems of patients after frontal damages what additionally stress the functional link between these two brain structures. Patient’s with cerebellar damages should have neuropsychological and neuropsychiatric diagnosis and care.

    Full Text Available Emulating the input-output functions performed by a brain structure opens the possibility for developing neuro-prosthetic systems that replace damaged neuronal circuits. Here, we demonstrate the feasibility of this approach by replacing the cerebellar circuit responsible for the acquisition and extinction of motor memories. Specifically, we show that a rat can undergo acquisition, retention and extinction of the eye-blink reflex even though the biological circuit responsible for this task has been chemically inactivated via anesthesia. This is achieved by first developing a computational model of the cerebellar microcircuit involved in the acquisition of conditioned reflexes and training it with synthetic data generated based on physiological recordings. Secondly, the cerebellar model is interfaced with the brain of an anesthetized rat, connecting the model's inputs and outputs to afferent and efferent cerebellar structures. As a result, we show that the anesthetized rat, equipped with our neuro-prosthetic system, can be classically conditioned to the acquisition of an eye-blink response. However, non-stationarities in the recorded biological signals limit the performance of the cerebellar model. Thus, we introduce an updated cerebellar model and validate it with physiological recordings showing that learning becomes stable and reliable. The resulting system represents an important step towards replacing lost functions of the central nervous system via neuro-prosthetics, obtained by integrating a synthetic circuit with the afferent and efferent pathways of a damaged brain region. These results also embody an early example of science-based medicine, where on the one hand the neuro-prosthetic system directly validates a theory of cerebellar learning that informed the design of the system, and on the other one it takes a step towards the development of neuro-prostheses that could recover lost learning functions in animals and, in the longer term

    The midbrain-hindbrain boundary (MHB) is a well-known organizing center during vertebrate brain development. The MHB forms at the expression boundary of Otx2 and Gbx2, mutually repressive homeodomain transcription factors expressed in the midbrain/forebrain and anterior hindbrain, respectively. The genetic hierarchy of gene expression at the MHB is complex, involving multiple positive and negative feedback loops that result in the establishment of non-overlapping domains of Wnt1 and Fgf8 on either side of the boundary and the consequent specification of the cerebellum. The cerebellum derives from the dorsal part of the anterior-most hindbrain segment, rhombomere 1 (r1), which undergoes a distinctive morphogenesis to give rise to the cerebellar primordium within which the various cerebellar neuron types are specified. Previous studies in the mouse have shown that Gbx2 is essential for cerebellar development. Using zebrafish mutants we show here that in the zebrafish gbx1 and gbx2 are required redundantly for morphogenesis of the cerebellar primordium and subsequent cerebellar differentiation, but that this requirement is alleviated by knocking down Otx. Expression of fgf8, wnt1 and the entire MHB genetic program is progressively lost in gbx1-;gbx2- double mutants but is rescued by Otx knock-down. This rescue of the MHB genetic program depends on rescued Fgf signaling, however the rescue of cerebellar primordium morphogenesis is independent of both Gbx and Fgf. Based on our findings we propose a revised model for the role of Gbx in cerebellar development.

    Deficiency of vitamin K predisposes to early, classic or late hemorrhagic disease of the newborn (HDN); late HDN may be associated with serious and life-threatening intracranial hemorrhage. Late HDN is characterized by intracranial bleeding in infants aged 1 week to 6 months due to severe vitamin K deficiency, occurring particularly in exclusively breastfed infants. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. In this study, we report on two siblings with intracranial bleeding who were fully breastfed without a routine supplementation of vitamin K. Vitamin K should be given to all newborns as a single, intramuscular dose of 1 mg.

    Gait and limb incoordination and ataxia are most often found in patients with brainstem and cerebellar infarcts and hemorrhages. Lesions involving the thalamus and the deep portions of the cerebral hemispheres also may cause ataxia accompanied by weakness and sensory symptoms. Patients who have lesions in the lateral medulla and inferior cerebellum often topple, lean, or veer when attempting to sit, stand, or walk. They list to the side or abruptly veer when walking. The affected limbs are often hypotonic. In pontine lesions, ataxia is accompanied by weakness and pyramidal tract signs as part of an ataxic hemiparesis syndrome. In lesions affecting the superior cerebellum and the brachium conjunctivum, limb dysmetria and overshoot and dysarthria predominate and gait ataxia is absent or slight and transient. Infarcts affecting the thalamus can cause gait instability and astasia with ataxia. Lateral thalamic lesions are characterized by hemisensory symptoms, extrapyramidal limb postures and dysfunction, and gait ataxia. Lesions that affect the posterior limb of the internal capsule and its afferent and efferent projections may also cause an ataxic hemiparesis syndrome, often with accompanying hemisensory abnormalities.

    Full Text Available Pancreatic pseudocyst is the most common cystic lesion of the pancreas seen following acute and chronic pancreatitis in 2-10% and 10-30%, respectively. Imaging findings vary depending on the age and severity of the attack. Infection, hemorrhage and rupture are the most frightening complications. The possibility of spontaneous recovery is consider­ably low. A 63-year old male patient who has history of longstanding alcohol consumption presented to the emer­gency department with complaints of abdominal pain. On computerized tomography (CT, an encapsulated and round peripancreatic collection with a size of approximately 8.5x7.5 cm was detected in pancreatic head. In the literature, no article is published mentioning coexistence of complication such as infection, hemorrhage and rupture. We present the association of these three complications observed in our case. J Clin Exp Invest 2016; 7 (2: 203-206

    Intraventricular hemorrhage during pregnancy is usually followed by a poor recovery. When caused by moyamoya disease, ischemic or hemorrhagic episodes may complicate the management of high intracranial pressure. A 26-year-old Caucasian woman presented with generalized seizures and a Glasgow Coma Score (GCS) of 3 during the 36th week of pregnancy. The fetus was delivered by caesarean section. The brain CT in the mother revealed bilateral intraventricular hemorrhage, a callosal hematoma, hydrocephalus and right frontal ischemia. Refractory high intracranial pressure developed and required bilateral ventricular drainage and intensive care treatment with barbiturates and hypothermia. Magnetic resonance imaging and cerebral angiography revealed a moyamoya syndrome with rupture of the abnormal collateral vascular network as the cause of the hemorrhage. Intracranial pressure could only be controlled after the surgical removal of the clots after a large opening of the right ventricle. Despite an initially low GCS, this patient made a good functional recovery at one year follow-up. Management of refractory high intracranial pressure following moyamoya related intraventricular bleeding should require optimal removal of ventricular clots and appropriate control of cerebral hemodynamics to avoid ischemic or hemorrhagic complications.

Aims of the study were to determine the average body weight, Apgar score after one and five minutes, and the frequency of the most common complications in preterminfants.Methods: The study involved a total of 631 newborns, of whom 331 were born prematurely Aims of this study were to (24th-37th gestational weeks-experimental group, while 300 infants were born in time (37-42 weeks of gestation-control group.Results: Average body weight of prematurely born infants was 2382 grams, while the average Apgar score in this group after the fi rst minute was 7.32 and 7.79 after the fifth minute. The incidence of respiratory distress syndrome was 50%, intracranial hemorrhage, 28.1% and 4.8% of sepsis. Respiratory distresssyndrome was more common in infants born before 32 weeks of gestation. Mortality of premature infants is present in 9.1% and is higher than that of infants born at term.Conclusions: Birth body weight and Apgar scores was lower in preterm infants. Respiratory distress syndrome is the most common fetal complication of prematurity. Intracranial hemorrhage is the second most common complication of prematurity. Mortality of premature infants is higher than the mortality of infants born at term birth.

    Full Text Available Intracranial hemorrhage is one of the major causes of neonatal mortality and morbidity. It is the most severe cranial problem in that period. Those who survive would be affected by hydrocephalus, encephalomalacia, and finally brain atrophy. With accurate knowledge of risk factors, hemorrhage may be diagnosed earlier and the complications managed earlier. This study was performed in Neonatal Intensive Care Unit of Imam Khomeini Hospital. All the neonates less than 34 weeks of gestation were undergone intracranial sonography from Feb 2005 to Feb 2006. Sonography was performed via anterior fontanel with proper probe according to neonatal age. 113 neonates less than 34 weeks of gestation have been studied. Mean gestational age was 32 weeks. Mean neonatal weight were 1566 ± 734 grams. Intracranial hemorrhage was evident in 21% of them; 16.8% was grade 1, 0.9% grade 2, 2.7% grade 3, 0.9% grade 4. The mean weight of neonates with hemorrhage was 1504.11 grams. Intracranial hemorrhage had correlation with respiratory acidosis and pneumothorax. The latter was also correlated with hemorrhage grade. Supposing the safety and non-invasiveness of intacranial sonography, we suggest performing sonography in all premature neonates with low birth weight, and also in those neonates with pneumothorax and respiratory acidosis.

    Interactions between the cerebellum and primary motor cortex are crucial for the acquisition of new motor skills. Recent neuroimaging studies indicate that learning motor skills is associated with subsequent modulation of resting-state functional connectivity in the cerebellar and cerebral cortices. The neuronal processes underlying the motor-learning-induced plasticity are not well understood. Here, we investigate changes in functional connectivity in source-reconstructed electroencephalography (EEG) following the performance of a single session of a dynamic force task in twenty young adults. Source activity was reconstructed in 112 regions of interest (ROIs) and the functional connectivity between all ROIs was estimated using the imaginary part of coherence. Significant changes in resting-state connectivity were assessed using partial least squares (PLS). We found that subjects adapted their motor performance during the training session and showed improved accuracy but with slower movement times. A number of connections were significantly upregulated after motor training, principally involving connections within the cerebellum and between the cerebellum and motor cortex. Increased connectivity was confined to specific frequency ranges in the mu- and beta-bands. Post hoc analysis of the phase spectra of these cerebellar and cortico-cerebellar connections revealed an increased phase lag between motor cortical and cerebellar activity following motor practice. These findings show a reorganization of intrinsic cortico-cerebellar connectivity related to motor adaptation and demonstrate the potential of EEG connectivity analysis in source space to reveal the neuronal processes that underpin neural plasticity.

    The cerebellum is a highly conserved structure in the central nervous system of vertebrates, and is involved in the coordination of voluntary motor behavior. Supporting this function, the cerebellar cortex presents a layered structure which requires precise spatial and temporal coordination of proliferation, migration, differentiation, and apoptosis events. The formation of the layered structure in the developing cerebellum remains unclear. The present study investigated the development of the cerebellar cortex. The results demonstrate that the primordium of the cerebellum comprises the ependymal, mantle, and marginal layers at embryonic day 12 (E12). Subsequently, the laminated cerebellar cortex undergoes cell proliferation, differentiation, and migration, and at about postnatal day 0 (P0), the cerebellar cortex presents an external granular layer, a molecular layer, a Purkinje layer, and an internal granular layer. The external granular layer is thickest at P6/7 and disappears at P20. From P0 to P30, the internal granular cells and the Purkinje cells gradually differentiate and develop until maturity. Apoptotic neurons are evident in the layered structure in the developing cerebellar cortex. The external granular layer disappears gradually because of cell migration and apoptosis. The cells of the other layers primarily undergo differentiation, development, and apoptosis.

    Unilateral ablation of cerebral cortical areas 4 and 6 of Brodmann in the macaque monkey results in a contralateral hemiplegia that resolves partially with time. During the phase of dense hemiplegia, local cerebral metabolic rate for glucose (1CMRG1c) is decreased significantly in most of the thalamic nuclei ipsilateral to the ablation, and there are slight contralateral decreases. The lCMRGlc is reduced bilaterally in most of the brainstem nuclei and bilaterally in the deep cerebellar nuclei, but only in the contralateral cerebellar cortex. During the phase of partial motor recovery, lCMRGlc is incompletely restored in many of the thalamic nuclei ipsilateral to the ablation and completely restored in the contralateral nuclei. In the brainstem and deep cerebellar nuclei, poor to moderate recovery occurs bilaterally. Moderate recovery occurs in the contralateral cerebellar cortex. The findings demonstrate that a unilateral cerebral cortical lesion strongly affects lCMRGlc in the thalamus ipsilaterally and in the cerebellar cortex contralaterally, but in the brainstem bilaterally. Partial recovery of lCMRGlc accompanies the progressive motor recovery. The structures affected include those with direct, and also those with indirect, connections to the areas ablated.

    The role of the cerebellum has been increasingly recognized not only in motor control but in sensory, cognitive and emotional learning and regulation. Purkinje cells, being the sole output from the cerebellar cortex, occupy an integrative position in this network. Plasticity at this level is known to critically involve calcium signaling. In the last few years, electrophysiological study of genetically engineered mice has demonstrated the topical role of several genes encoding calcium-binding proteins (calretinin, calbindin, parvalbumin). Specific inactivation of these genes results in the emergence of a fast network oscillation (ca. 160 Hz) throughout the cerebellar cortex in alert animals, associated with ataxia. This oscillation is produced by synchronization of Purkinje cells along the parallel fiber beam. It behaves as an electrophysiological arrest rhythm, being blocked by sensorimotor stimulation. Pharmacological manipulations showed that the oscillation is blocked by GABA(A) and NMDA antagonists as well as gap junction blockers. This cerebellar network oscillation has also been documented in mouse models of human conditions with complex developmental cerebellar dysfunction, such as Angelman syndrome and fetal alcohol syndrome. Recent evidence suggests a relationship between fast oscillation and cerebellar long term depression (LTD). This may have major implications for future therapeutic targeting.

    Moyamoya disease (MMD) is a chronic progressive cerebrovascular disease, which can be divided into three types: ischemic, hemorrhagic, and asymptomatic. Hemorrhagic MMD has attracted considerable attention due to its distinctive imaging features and the controversy over the treatment. This report presents a comprehensive review of the literature on hemorrhagic MMD, focusing on the epidemiological characteristics, etiology and pathogenesis, imaging features, predictors of hemorrhage, and treatment options and their efficacy of hemorrhagic MMD. Hemorrhagic MMD mainly occurs in adult patients in Asian countries, and many factors may contribute to the etiology and development of this disease. Hemorrhagic MMD has two major imaging features: the dilatation and abnormal branching of anterior choroidal artery or posterior communicating artery, and multiple microbleeds, which may predict subsequent hemorrhage. The treatment for hemorrhagic MMD is not standardized, and large sample prospective randomized clinical trials may help to determine which method is better. In hemorrhagic MMD patients, more attention should be paid to cognitive function and quality of life, and these assessments should be included in the evaluation of effectiveness of treatment modalities.

    Full Text Available In this paper, we created a decision-making model to detect intracranial hemorrhage and adopted Expectation Maximization(EM segmentation to segment the Computed Tomography (CT images. In this work, basically intracranial hemorrhage is classified into two main types which are intra-axial hemorrhage and extra-axial hemorrhage. In order to ease classification, contrast enhancement is adopted to finetune the contrast of the hemorrhage. After that, k-means is applied to group the potential and suspicious hemorrhagic regions into one cluster. The decision-making process is to identify whether the suspicious regions are hemorrhagic regions or non-regions of interest. After the hemorrhagic detection, the images are segmented into brain matter and cerebrospinal fluid (CSF by using expectation-maximization (EM segmentation. The acquired experimental results are evaluated in terms of recall and precision. The encouraging results have been attained whereby the proposed system has yielded 0.9333 and 0.8880 precision for extra-axial and intra-axial hemorrhagic detection respectively, whereas recall rate obtained is 0.9245 and 0.8043 for extra-axial and intra-axial hemorrhagic detection respectively.

    Late embryonic and postnatal cerebellar folial surface area expansion promotes cerebellar cortical cytoarchitectural lamination. We developed a streamlined sampling scheme to generate unbiased estimates of murine cerebellar surface area and volume using stereological principles. We demonstrate that during the proliferative phase of the external granule layer (EGL) and folial surface area expansion, EGL thickness does not change and thus is a topological proxy for progenitor self-renewal. The topological constraints indicate that during proliferative phases, migration out of the EGL is balanced by self-renewal. Progenitor self-renewal must, therefore, include mitotic events yielding either 2 cells in the same layer to increase surface area (β-events) and mitotic events yielding 2 cells, with 1 cell in a superficial layer and 1 cell in a deeper layer (α-events). As the cerebellum grows, therefore, β-events lie upstream of α-events. Using a mathematical model constrained by the measurements of volume and surface area, we could quantify inter-mitotic times for β-events on a per-cell basis in post-natal mouse cerebellum. Furthermore, we found that loss of CCNA2, which decreases EGL proliferation and secondarily induces cerebellar cortical dyslamination, shows preserved α-type events. Thus, CCNA2-null cerebellar granule progenitor cells are capable of self-renewal of the EGL stem cell niche; this is concordant with prior findings of extensive apoptosis in CCNA2-null mice. Similar methodologies may provide another layer of depth to the interpretation of results from stereological studies. PMID:25668568

After performing paracentesis of the anterior chamber, 0.3 ml pure SF6 gas was injected through pars plana with a 30 gauge needle. Facedown position was maintained for 5 days. Subhyaloid Hemorrhage was displaced in 4/5 (80% eyes with a duration of SHH less than 2 weeks. The pre-injection visual acuity of all 5 eyes was finger counting and improved in 4/5 ( 80% eyes within 3 days to 7 days post-injection to 6/20 - 6/6. The underlying disease was hypercoagulation in 1 patient, diabetes mellitus in 2 patients, hypertension in 1 patient and unknown in 1 patient. No complications were encountered. In conclusion, SF6 gas injected into the vitreous without the use of tPA, can displace SHH if performed within 14 days of duration, and results in rapid visual recovery. This procedure is proven to be safe. (Med J Indones 2007; 16:104-7 Keywords: subhyaloid hemorrhage, pneumatic displacement, sulfur hexafluoride gas

    Most pancreatic pseudocysts are common complications of acute or chronic pancreatitis. They usually occur within the pancreas or in peripancreatic tissues, and are visualized as round or oval fluid collections with thin or thick walls on computed tomography (CT) scans. However, pancreatic pseudocysts are often combined with various complications, e.g., various organ involvements, infection, hemorrhage with pseudoaneurysm formation, rupture with fistula formation, or gastrointestinal or biliary obstruction, which may necessitate prompt intervention or surgery. This review illustrates the CT appearances of various complications associated with pancreatic pseudocysts

    We report on the case of a huge varix that developed after the endovascular embolization of a cerebellar arteriovenous malformation (AVM) with a single drainer. A 21-year-old male presented with trigeminal neuralgia which was caused by the dilated drainer of the AVM. A varix was found at the basal vein of Rosenthal 2 months after an initial stage of embolization with polyvinyl alcohol particles; it diminished after the surgical extirpation of the AVM. The varix formation might have been facilitated by the stenosis in the vein of Galen and by the dynamic changes that followed the embolization. This rare complication should be kept in mind when embolization is performed for AVMs with impaired venous outlets. (orig.).

    Acute cholecystitis is a common cause of abdominal pain in the Western world. Unless treated promptly, patients with acute cholecystitis may develop complications such as gangrenous, perforated, or emphysematous cholecystitis. Because of the increased morbidity and mortality of complicated cholecystitis, early diagnosis and treatment are essential for optimal patient care. Nevertheless, complicated cholecystitis may pose significant challenges with cross-sectional imaging, including sonography and computed tomography (CT). Interpreting radiologists should be familiar with the spectrum of sonographic findings seen with complicated cholecystitis and as well as understand the complementary role of CT. Worrisome imaging findings for complicated cholecystitis include intraluminal findings (sloughed mucosa, hemorrhage, abnormal gas), gallbladder wall abnormalities (striations, asymmetric wall thickening, abnormal gas, loss of sonoreflectivity and contrast enhancement), and pericholecystic changes (echogenic fat, pericholecystic fluid, abscess formation). Finally, diagnosis of complicated cholecystitis by sonography and CT can guide alternative treatments including minimally invasive percutaneous and endoscopic options.

    Understanding the technical constructs of bariatric surgery is important to the treating endoscopist to maximize effective endoluminal therapy. Post-operative complication rates vary widely based on the complication of interest, and have been reported to be as high as 68% following adjustable gastric banding. Similarly, there is a wide range of presenting symptoms for post-operative bariatric complications, including abdominal pain, nausea and vomiting, dysphagia, gastrointestinal hemorrhage, and weight regain, all of which may provoke an endoscopic assessment. Bleeding and anastomotic leak are considered to be early ( 30 d) complications. Treatment of complications in the immediate post-operative period may require unique considerations. Endoluminal therapies serve as adjuncts to surgical and radiographic procedures. This review aims to summarize the spectrum and efficacy of endoscopic management of post-operative bariatric complications.

    The complications observed following transcatheter phlebography can be grouped into general side effects/complications, general complications due to the method applied, and local complications, with the latter in most cases resulting from the position of the catheter tip during injection, i.e. from damage to the soft vessels. Suprarenal phlebography bears the risk of adrenal insufficiency, or infarction (frequency of 5% up to 9%). The complications observed after pulmonalis angiography are heart injuries, arrhythmiae, lung oedemas, asthmatic attacks, pectoral pain, and fistula formation in the bronchial arteries (frequency of 1% up to 15.4%, lethality 0.2% up to 1.4%). Transumbilical portography and percutanous transhepatic portography may lead to complications such as thrombosis of the portal vein, intraperitoneal hemorrhage, ascites escape, biliary peritonitis, and punturing of neighbour organs (morbidity of 0 to 67%, lethality of 0 to 0.67%).

    Approximately 50% of patients with the genetic disease tuberous sclerosis complex present with autism spectrum disorder. Although a number of studies have investigated the link between autism and tuberous sclerosis complex, the etiology of autism spectrum disorder in these patients remains unclear. Abnormal cerebellar function during critical phases of development could disrupt functional processes in the brain, leading to development of autistic features. Accordingly, the authors review the potential role of cerebellar dysfunction in the pathogenesis of autism spectrum disorder in tuberous sclerosis complex. The authors also introduce conditional knockout mouse models of Tsc1 and Tsc2 that link cerebellar circuitry to the development of autistic-like features. Taken together, these preclinical and clinical investigations indicate the cerebellum has a profound regulatory role during development of social communication and repetitive behaviors.

  5. An unusual cause of adult onset cerebellar ataxia with hypogonadism

    Full Text Available We report an unusual case of sporadic adult onset cerebellar ataxia with hypogonadism. A 40-year-old unmarried man presented with progressive ataxia and dysarthria along with complaints of non-development of secondary sexual characteristics and erectile dysfunction. There were complaints of intermittent diarrhea. Clinical examination revealed a pan-cerebellar syndrome with features of hypoandrogenism. No eye movement abnormalities were evident. There were signs of malabsorption. Investigations confirmed the presence of auto-antibodies found in celiac disease, and a duodenal biopsy confirmed the same. Hypoandrogenism was postulated to be due to hypergonadotropic hypogonadism which has been mentioned in a few patients of celiac disease. However, the pattern seen in our patient was of a hypogonadotropic hypogonadism. This is probably secondary to an autoimmune hypophysitis seen in some patients in the absence of other clinical manifestations. Autoantibody testing should be a diagnostic necessity in any adult with a sporadic cerebellar ataxia.

    Viral hemorrhagic fever (VHF) is defined as virus infections that usually cause pyrexia and hemorrhagic symptoms with multiple organ failure. VHF includes following viral infections: Ebola hemorrhagic fever (EHF), Marburg hemorrhagic fever (MHF), Crimean-Congo hemorrhagic fever (CCHF) and Lassa fever. In particular, the causative agents of EHF, MHF, CCHF, and Lassa fever are Ebola, Marburg, CCHF, Lassa viruses, respectively, and regarded as biosafety level-4 pathogens because of their high virulence to humans. Recently, relatively large outbreaks of EHF and MHF have occurred in Africa, and areas of EHF- and MHF-outbreaks seem to be expanding. Although outbreaks of VHF have not been reported in Japan, there is a possibility that the deadly hemorrhagic fever viruses would be introduced to Japan in future. Therefore, preparedness for possible future outbreaks of VHF is necessary in areas without VHF outbreaks.

    We studied the relationship between outcome and clinical symptoms or CT findings of 34 cases with primary pontine hemorrhage diagnosed by CT scan from April 1994 to March 1999. This series comprised 19 males and 15 females ranging in age from 45 to 89 years with a mean of 67.1 years. According to their outcome at discharge, the cases were divided into 6 groups. Sixteen cases died within 2 weeks after onset (group AD), 4 cases died with complication in the chronic phase (group D), 3 cases were severely disabled to bed-ridden state (group C), 2 cases recovered to a daily life with wheelchair (group B), 4 cases recovered to a daily life with partial assistance (group A), and 5 cases showed a full recovery (group J). The factors significantly correlated with bed outcome are as follows: young age, consciousness disturbance, respiratory disturbance, tachycardia over 90 beats per minute, hyperthermia over 39 deg C, abnormal pupils, loss of oculocephalic reflex, tetraplegia, decerebrate rigidity, bilateral extension or over 30 mm transverse diameter of the hematoma.

    We evaluate regional cerebral and cerebellar perfusion to prove the occurrence and follow the persistence of crossed cerebellar diaschisis in infratentorial pontine infarction. Six consecutive patients exhibiting mild hemiparetic symptoms or a heavy feeling in the head (mean age 65 years; four women, two men) and diagnosed as having pontine infarction by magnetic resonance imaging were sugjected to evaluation. Lesions due to infarction were located at the upper basis pontis in five partients and the upper tegmentum pontis in one, and medially at the paramedian portion in four and laterally in two. Regional cerebral and cerebellar perfusion was evaluated semiquantitatively by iodine-123 N-isopropyl-p-iodoamphetamine (IMP) single-photon emission tomography (SPET); this was done during the acute stage in five cases (mean time after onset: 0.7 months) and during the chronic stage in three (mean time after onset: 14.8 months) Significant asymmetry in cerebellar perfusion, which was reduced in the contralateral or ipsilateral cerebellar hemisphere, was demonstrated semiquantitatively in four cases during the acute stage and in one during the chronic stage, as compared with normal controls. This asymmetry continued to the chronic stage (6.5 and 33.0 months) in two cases, while no patient showed any significant asymmetries in cerebral perdusion in any region of interest in either SPET study. The pontine lesion may damage the pyramidal tract and corticocerebellar pathway, and interruption of the cerebrocerebellar pontine circuits may be regarded as the cause of the crossed cerebellar diaschisis observed in five of the six reported patients with pontine infarction.

  14. Cerebellar substrates for error correction in motor conditioning.

    Science.gov (United States)

    Gluck, M A; Allen, M T; Myers, C E; Thompson, R F

    2001-11-01

    The authors evaluate a mapping of Rescorla and Wagner's (1972) behavioral model of classical conditioning onto the cerebellar substrates for motor reflex learning and illustrate how the limitations of the Rescorla-Wagner model are just as useful as its successes for guiding the development of new psychobiological theories of learning. They postulate that the inhibitory pathway that returns conditioned response information from the cerebellar interpositus nucleus back to the inferior olive is the neural basis for the error correction learning proposed by Rescorla and Wagner (Gluck, Myers, & Thompson, 1994; Thompson, 1986). The authors' cerebellar model expects that behavioral processes described by the Rescorla-Wagner model will be localized within the cerebellum and related brain stem structures, whereas behavioral processes beyond the scope of the Rescorla-Wagner model will depend on extracerebellar structures such as the hippocampus and related cortical regions. Simulations presented here support both implications. Several novel implications of the authors' cerebellar error-correcting model are described including a recent empirical study by Kim, Krupa, and Thompson (1998), who verified that suppressing the putative error correction pathway should interfere with the Kamin (1969) blocking effect, a behavioral manifestation of error correction learning. The authors also discuss the model's implications for understanding the limits of cerebellar contributions to associative learning and how this informs our understanding of hippocampal function in conditioning. This leads to a more integrative view of the neural substrates of conditioning in which the authors' real-time circuit-level model of the cerebellum can be viewed as a generalization of the long-term memory module of Gluck and Myers' (1993) trial-level theory of cerebellar-hippocampal interaction in motor conditioning.

  15. Emotional disorders in patients with cerebellar damage – case studies

    Directory of Open Access Journals (Sweden)

    Siuda, Katarzyna

    2014-04-01

    Full Text Available Aim: Growing number of research shows the role of the cerebellum in the regulation of affect. Lesions of the cerebellum can lead to emotional disregulation, a significant part of the Cerebellar Cognitive Affective Syndrome. The aim of this article is to analyze the most recent studies concerning the cerebellar participation in emotional reactions and to present three cases: two female and one male who suffered from cerebellar damage and presented post-traumatic affective and personality change. Method: The patients’ neuropsychological examination was performed with Raven’s Progressive Matrices Test – standard version, Trial Making Test, Wisconsin Card Sorting Test, Auditory Verbal Learning Test by Łuria, Benton Visual Retention Test, Verbal Fluency Test, Stroop Interference Test, Attention and Perceptivity Test (Test Uwagi i Spostrzegawczości TUS, Frontal Behavioral Inventory (FBI. Results: The review of the literature suggest cerebellar participation, especially teh vermis and paravermial regions, in the detection, integration and filtration of emotional information and in regulation of autonomic emotional responses. In the described patients we observed: oversensitivity, irritability, impulsivity and self-neglect. The man and the woman with right-sided lesions presented similar symptoms: rigidity of thought, stubbornness, lack of criticism, jocular and inappropriate behavior. The woman with left-sided cerebellar lesion was adynamic, apathic and passive, she presented emotional blunting, social isolation, lack of interests and motivation, general cognitive slowdown. Conclusions: Both the analyzed research and the described cases indicate the connection between the cerebellum and emotion regulation. The symptoms presented by the described patients were most probably a consequence of damaged cerebellar projections to subcortical structures (the limbic system and frontal areas. The diversification of symptoms depending on the localization

    Influenza-associated encephalitis (IAE) is a complication of a common disease that is rare even during an epidemic. Awareness of magnetic resonance imaging features of IAE is important in treatment planning and prognosis estimation. Several reports have described necrotizing encephalopathy in children with influenza. However, few reports have described multifocal hemorrhages in both cerebral hemispheres in adults with concomitant infection with influenza A and B. Here, we describe a case of influenza A- and B-associated encephalitis accompanied by numerous cerebral hemorrhages.

    Spontaneous subperiosteal hemorrhage is a rare complication of von Recklinghausen's disease. There are few reports describing the MR imaging characteristics of this entity. Our case is unique among these as an underlying plexiform neurofibroma was visualized by MR imaging. We present a 12-year-old child with neurofibromatosis 1 who presented with a rapidly enlarging mass of the fibula. Surgery and pathology revealed subperiosteal hemorrhage into a benign, plexiform neurofibroma. The MR imaging features, pathogenesis and clinical implications of this entity are discussed. Recognition of this disease process and differentiating it from malignant transformation can prevent unnecessary surgery. (orig.)

  18. Delayed hemorrhage from hepatic artery after ultrasound-guided percutaneous liver biopsy: A case report

    Institute of Scientific and Technical Information of China (English)

    Fen-Yu Ren; Xi-Xu Piao; Ailian Jin

    2006-01-01

    Percutaneous liver biopsy is considered one of the most important diagnostic tools to evaluate diffuse liver diseases. Pseudoaneurysm of hepatic artery is an unusual complication after ultrasound-guided percutaneous liver biopsy. Delayed hemorrhage occurs much less frequently. We report a case of pseudoaneurysm of the hepatic artery of a 46-year-old man who was admitted for abdominal pain after 4 d of liver biopsy. The bleeding was controlled initially by angiographic embolization.However, recurrent bleeding could not be controlled by repeat angiography, and the patient died 4 d after admission from multiorgan failure. The admittedly rare possibility of delayed hemorrhage should be considered whenever a liver biopsy is performed.

    Background The natural course of submacular hemorrhage resulting from traumatic choroidal rupture generally has a poor outcome unless treated. The intravitreal injection of gas only or gas with recombinant tissue plasminogen activator (rt-PA) has been reported to be effective, but has also been reported to induce severe complications such as retinal detachment and vitreous hemorrhage. Recently, we reported a safe and effective procedure for treating submacular hemorrhage due to polypoidal cho...
