    We reviewed the clinical and radiological features of ten patients with small arteriovenous malformations that caused intracerebral hematomas. In six patients, angiography showed a small nidus (less than 1 cm in diameter) with a shunt at the site of the hematoma, and in four only an early-filling vein was evident. Six patients had only delayed angiography (4 weeks or more after the ictus). In three, angiography within 2 days of the ictus failed to reveal the cause of the bleed, but repeat angiography showed an early-filling vein in two, and a nidus with shunting in one. In only one patient did early angiography reveal the malformation. MRI was obtained in eight patients, and in two prominent vessels were evident in the wall of the hematoma cavity. In investigation of an unexplained intracerebral hematoma, MRI may be useful to exclude a neoplasm or cavernoma, although the latter may be not be evident in the presence of a recent hematoma. We suggest early MRI and angiography for investigation of an unexplained, nonhypertensive intracerebral bleed, with follow-up MRI and dealyed angiography if the initial studies fail to reveal the cause.

    Full Text Available Three patients of delayed extradural hematoma (EDH were seen in the last one year among forty eight consecutively treated cases of EDH. All the three hematomas were evacuated. Awareness of this entity and a high degree of vigilance are strongly recommended to detect such cases. Repeat CT should always be done, especially after decompression by either surgical or medical means, recovery from shock or whenever there is evidence of even minimal bleeding under a skull fracture on initial CT scan.

    Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

    Full Text Available Abstract Background We report a case of severe upper airway obstruction due to a retropharyngeal hematoma that presented nearly one day after a precipitating traumatic injury. Retropharyngeal hematomas are rare, but may cause life-threatening airway compromise. Case presentation A 50 year-old man developed severe dyspnea with oropharyngeal airway compression due to retropharyngeal hematoma 20 hours after presenting to the emergency department. The patient also had a fractured first cervical vertebra and was diagnosed with a left brachial plexopathy. The patient underwent emergent awake fiberoptic endotracheal intubation to provide a definitive airway. Conclusion Retropharyngeal hematoma with life-threatening airway compromise can develop hours or days after a precipitating injury. Clinicians should be alert to the potential for this delayed airway collapse, and should also be prepared to rapidly secure the airway in this patient population likely to have concomitant cervical spinal or head injuries.

    HELLP (hemolysis, elevated liver enzymes and low platelets) syndrome is an obstetric complication with heterogeneous presentation, multisystem involvement and variable prognosis, but which usually resolves after delivery. We report a case of HELLP syndrome with subcapsular hematoma of the liver causing extrapericardial cardiac tamponade. The subcapsular hematoma and cardiac tamponade were managed conservatively.

  6. Analysis of infantile subdural hematoma caused by abuse

    International Nuclear Information System (INIS)

    We report infantile subdural hematoma caused by abuse. Between January 2006 and December 2009, 10 cases of definite and highly suspicious abusive subdural hematoma in infants were treated at Nara Medical University Hospital. The mean age was 5.4 months. On CT examination, severe cerebral swelling was seen in 8 (80%) and wide spreading cerebral ischemia and atrophy in 9 (90%). Retinal hemorrhage was commonly seen in this series (90%). Subdural drainage and/or subdural-peritoneal shunt surgeries were performed in 6 cases, and intensive combined therapy of mild hypothermia and barbiturate was adapted in 7 cases. Favorable outcome was achieved in only 3 cases. In spite of aggressive treatment, clinical outcome are still bad. In our series, assailants were predominantly not father but mother. There were various and complex factors for child abuse. Cautious insight and suspicion are necessary to detect abusive injuries in infants. It is very important to endeavor to prevent recurrences of abusive injuries. (author)

    Full Text Available Small bowel obstruction due to intramural hematoma secondary to anticoagulant therapy is a rare complication. Other risk factors include hemophilia, idiopathic thrombocytopenic purpura, leukemia, lymphoma, myeloma, chemotherapy, vasculitis, pancreatitis, and pancreatic cancer. The presentation of patients is usually with abdominal pain, nause and vomiting. The patients who were admitted to the emergency clinic with acute abdominal pain and had a history of anticoagulant use with prolonged international normalized ratios should alert to search for intraabdominal hematoma. Herein, we present a patient who was admitted to the emergency clinic with acute abdominal pain, severe nausea and vomiting, and diagnosed by abdominal computed tomography.

    Full Text Available Oral anticoagulant therapy (OAT is very effective in the prevention of cerebralembolism, especially in certain cardiac diseases. Hematomas are the majorcomplication of OAT. It may threaten the patient’s life by bleeding into the vitalstructures. Herein, we describe four patients with hematomas in the psoas,quadriceps, pectoral, or rectus abdominis muscles accompanied by anemiaduring warfarin therapy for atrial fibrillation and artificial heart valves. Computedtomography and magnetic resonance imaging helped us establish a definitivediagnosis in each case. Our patients were three women and one man. Theirinternational normalized ratios were within the therapeutic range during thisperiod. They suffered from minor traumas, such as falls or a hit while takingwarfarin therapy. All anticoagulation treatments were discontinued for approximately1 week after the episode of bleeding. Although conservative managementwas sufficient for three patients, one patient had surgical decompression due toa rectus abdominis hematoma with retroperitoneal hemorrhage. There were noepisodes of bleeding or other complications after starting oral anticoagulanttherapy during the follow-up. The common aspects of our cases were older ageand a history of minor trauma. As a result, we suggest that special attentionneeds to be paid to the patients under anticoagulant therapy, especially those atan advanced age, and to warn them avoid trauma.

    Full Text Available Abstract Background Abdominal wall hematomas are an uncommon cause of acute abdominal pain and are often misdiagnosed. They are more common in elderly individuals, particularly in those under anticoagulant therapy. Most abdominal wall hematomas occur in the rectus sheath, and hematomas within the oblique muscle are very rare and are poorly described in the literature. Here we report the case of an oblique muscle hematoma in a middle-aged patient who was not under anticoagulant therapy. Case presentation A 42-year-old Japanese man presented with a painful, enlarging, lateral abdominal wall mass, which appeared after playing baseball. Abdominal computed tomography and ultrasonography showed a large soft tissue mass located in the patient’s left internal oblique muscle. A diagnosis of a lateral oblique muscle hematoma was made and the patient was treated conservatively. Conclusion Physicians should consider an oblique muscle hematoma during the initial differential diagnosis of pain in the lateral abdominal wall even in the absence of anticoagulant therapy or trauma.

  15. Pathophysiological study of chronic subdural hematoma and communicating hydrocephalus with delayed MRI using Gd-DTPA (Magnevist)

    International Nuclear Information System (INIS)

    Concerning the pathophysiology of chronic subdural hematoma and communicating hydrocephalus, recent studies have been made, but no definitive conclusion has yet been attained. To study their complicated mechanisms, we examined a delayed MRI which was performed 4 hours after the intravenous injection of Gd-diethylenetriaminepentaacetic acid (Gd-DTPA) on 5 cases of subdural hygroma, 3 cases of chronic subdural hematoma after irrigation, one case of hydrocephalus with glioblastoma, and one case of Parkinson syndrome. In every case of subdural hygroma, it was certified that Gd-DTPA was leaked into the cavity of the subdural space. This is perhaps because the outer and inner membranes of the subdural hygroma consist of fibroblasts and of capillary vessels with fenestration; the leakage of blood composition through this fenestration may promote the growth of the membrane and the cavity. The leakage of Gd-DTPA decreased after irrigation, and it did not recur. In the case of hydrocephalus with gioblastoma, there was leakage of Gd-DTPA into the ventricles surrounding the tumor. This may be because of the destruction of the blood-cerebrospinal fluid barrier; perhaps this is associated with the cause of the communicating hydrocephalus. (author)

  17. Re-estimation of acute subdural hematoma in children caused by trivial household head trauma

    International Nuclear Information System (INIS)

    The objective of this study was to identify characteristics of acute subdural hematoma in children caused by a trivial household head trauma from a modem neurosurgical and medicolegal standpoint. We performed a retrospective study of 25 children younger than 48 months hospitalized for acute subdural hematoma from December 1, 1993, through February 28, 2003. Inclusion criteria were as follows: acute subdural hematoma caused by trivial household trauma and a history of trauma corroborated by a caretaker, absence of physical injuries consistent with child abuse, fundoscopic examinations performed by a pediatric ophthalmologist, absence of fractures on general bone survey, and child abuse ruled out by long-term follow-up (more than 5 years). Twenty-one of the patients were boys, and 4 were girls. The patients ranged in age from 6 to 17 months, with an average age of 8.5 months. In 17 of 25 patients trauma had been caused by falls to the floor while standing with support or while sitting. Most of the patients were admitted to the hospital because of generalized convulsions or seizures that had developed soon after a trivial household trauma. Fifteen of the 25 (60%) patients had retinal or preretinal hemorrhage and 9 patients had bilateral retinal hemorrhage. Computed tomography showed fluid-type acute subdural hematomas at the frontal convexity or in the interhemispheric fissure in 18 of 25 (72%) patients. Fourteen of 25 (56%) patients had pre-existing external hydrocephalus (enlargements of the subarachnoid space). The long-term outcomes included normal mental development (IQ≥80) in 18 cases, mild mental retardation (IQ<80) in 7 cases, and epilepsy in 3 cases. Acute subdural hematoma in children caused by trivial household trauma is a clinical entity distinct from acute subdural hematoma caused by child abuse or shaken-baby syndrome. (author)

    We experienced a case of epidural hematoma caused by coagulopathy 3 days after surgery. A 72-year-old man, who had undergone a total gastrectomy, suffered from nausea and vomiting by ileus. He underwent repair of ileus under general anesthesia with thoracic epidural anesthesia. Three days after surgery, abnormal bleeding followed by disorder of prothrombin activity (PT) and activated partial thromboplastin time (aPTT) and paralysis due to thoracic epidural hematoma developed. It was suspected that these coagulopathies were the results of vitamin K deficiency. Vitamin K deficiency in this patient was considered to have been caused by cephem antibiotics containing N-methyl-thiotetrazole (NMTT) side chain and no oral intake of food for a few days preoperatively. The patient was treated with fresh frozen plasma and intravenous menatetrenon, which improved abnormal bleeding and disorder of PT and aPTT within 24hr. After a discussion with orthopedic consultants, we selected a conservative therapy rather than surgical removal of the hematoma. Thoracic epidural hematoma disappeared two months after surgery, but motor paralysis requiring rehabilitation remained. In conclusion, when patients have not eaten anything for a few days and antibiotics with an NMTT sidechain has been administered, care must be taken to prevent vitamin K deficiency and coagulopathy.

    We report a case of a retroperitoneal hematoma occurring in a patient under anticoagulation therapy for deep-venous thrombosis and presenting as an anuric acute renal failure. A coexisting polycythemia vera led to misdiagnosis that could have been life-threatening. A woman, known for polycythemia vera and a single functioning right kidney, was admitted with mild abdominal pain in a context of recent deep venous thrombosis under low-molecular weight heparin. Clinical examination revealed hepatomegaly associated with polycythemia vera. Biochemical evaluation disclosed an acute renal failure, and renal ultrasonography showed no dilation of the renal pelvis. Retroperitoneal hematoma resulted in shock, progressive anemia and obstructive renal failure, related to renal pelvic compression. A right renal indwelling catheter was introduced to restore urine flow after one hemodialysis session, and an inferior vena cava filter was placed because of anti-coagulation contra-indication. However, pulmonary embolism occurred, so that oral anticoagulants were introduced. The hematoma resorbed spontaneously, and a year after this episode, the patient is still alive and well. Retroperitoneal hematoma is a rare cause of obstructive acute renal failure and a life-threatening complication of anti-coagulation therapy. PMID:17542341

    Abdominal wall pathology is a frequently overlooked cause of acute abdomen. Increasing use of antiplatelet and anticoagulant therapies has led to an increase in the incidence of spontaneous rectus sheath hematoma (RSH). A high index of suspicion is needed for diagnosis as it can closely mimic other causes of acute abdomen. Herein, we report a case of RSH presenting with abdominal pain in which there was a significant delay in diagnosis. We wish to highlight the need to increase awareness amon...

  1. An unusual cause of the acute abdomen: computed tomography angiography findings of the intestinal intramural hematoma

    International Nuclear Information System (INIS)

    Full text: Introduction: The intestinal intramural hematoma is a rare abdominal emergency condition resulting from submucosal or subserosal hemorrhage. The various causes of this condition are anticoagulant therapy, trauma, surgery, biopsy and spontaneous. The most common cause of this condition is blunt abdominal trauma. Objectives and tasks: In this report we aimed to present computed tomography (CT) angiography findings of the intestinal wall hematoma which is an unusual cause of acute abdomen. Materials and methods: A 67-year-old man presented to our emergency department complaining of severe abdominal pain, nausea and vomiting. The physical examination revealed right upper quadrant and epigastric abdominal tenderness. Sonographic examination revealed free fluid in the right paracolic area and minor pelvis. Due to these findings, the patient underwent CT angiography examination with suspicion of acute intestinal ischemia. Results: Diffuse atherosclerotic calcified plaques in the abdominal aorta and moderate degree stenosis proximal celiac truncus were determined on CT angiography images. Mesenteric arterial system was patent. On CT images most remarkable finding was diffuse wall thickening reaching up to 1.5 cm at the widest part in small intestinal segments. These findings were seen in the right half of abdomen and pelvis, approximately 12 cm and 20 cm small intestinal segment, respectively. The patient was using warfarin and acetylsalicylic acid medication due to heart valve replacement surgery. This history and CT angiography findings were consistent with intestinal mural hematoma. Conclusion: In the differential diagnosis of the acute abdomen, intestinal intramural hematoma must be kept in mind, especially in patients using anticoagulant drugs. In such cases, CT angiographic examination is rapid, effective and reliable method in both determination of the vascular abnormality and evaluation of the intestinal wall pathologies

  3. MR imaging of hyperacute intracranial hematomas

    International Nuclear Information System (INIS)

    A modification of the gradient-recalled-echo (GRE) pulse sequence, which we called hematoma sensitive GRE, was compared with CT and spin-echo (SE) MR images for patients suffering from parenchymal hemorrhage in the hyperacute stage (within 6 hours). In the hyperacute stage, CT was most sensitive to hematoma, and hematomas were visualized more clearly on GRE than SE. Hematomas and the surrounding tissues were almost isointense relative to white matter on T1-weighted images (WI), and hyperintense on T2-WI of SE. But they were visualized at different intensity from each other on GRE. Hematomas were hyperintense including hypointensity, and plasma was more hyperintense (similar to cerebrospinal fluid), and edematous tissue was slightly hyperintense relative to white matter. The changes of tissue surrounding hematoma were not detected on CT. Hematomas were iso- or hyperintense on SE in the acue stage, and were slightly hyperintense including hypointense areas with a surrounding hypointense rim on GRE. The change of intensity of hematoma was delayed on GRE compared to SE. This phenomenon was caused by lack of sensitivity to the intracellular methemoglobin. Thus it is possible to visualize the contents of hematoma on GRE in the acute stage. (author)

Mycoplasma hominis usually colonizes the lower urogenital tract and causes pyelonephritis, pelvic inflammatory disease, chorioamnionitis, rupture of fetal membranes, preterm labor, postpartum fever, postabortal fever, and neonatal infection. This organism is highly prevalent in cervicovaginal cultures of sexually active women. M. hominis, M. genitalis, Ureaplasma urealyticum, and U. parvum may invade and infect placental and fetal tissues, leading to adverse pregnancy outcomes. M. hominis occasionally causes nongenitourinary infection of the blood, wounds, central nervous system, joints, or respiratory tract. We present a case of a 27-year-old woman who developed abdominal wound hematoma and abscess after cesarean section. The wound was drained, but her high fever persisted, in spite of antibiotic treatment using flomoxef sodium and imipenem•cilastatin sodium. Because the exudate exhibited M. hominis growth in an anaerobic environment, we administered the quinolone ciprofloxacin. This therapy resolved her fever, and her white blood cell count and C-reactive protein level diminished to the normal ranges. To our knowledge, there are four published articles regarding the isolation of M. hominis from postcesarean incisions. Based on the current study and the literature, infection by this pathogen may cause hematoma formation with or without abscess after cesarean section or in immunosuppressed postoperative patients. In such cases, physicians may need to suspect Mycoplasma infection and initiate appropriate antibacterial treatment as soon as possible in order to avoid persistent fever.Keywords: Mycoplasma hominis, cesarean section, hematoma, abscess

Mycoplasma hominis usually colonizes the lower urogenital tract and causes pyelonephritis, pelvic inflammatory disease, chorioamnionitis, rupture of fetal membranes, preterm labor, postpartum fever, postabortal fever, and neonatal infection. This organism is highly prevalent in cervicovaginal cultures of sexually active women. M. hominis, M. genitalis, Ureaplasma urealyticum, and U. parvum may invade and infect placental and fetal tissues, leading to adverse pregnancy outcomes. M. hominis occasionally causes nongenitourinary infection of the blood, wounds, central nervous system, joints, or respiratory tract. We present a case of a 27-year-old woman who developed abdominal wound hematoma and abscess after cesarean section. The wound was drained, but her high fever persisted, in spite of antibiotic treatment using flomoxef sodium and imipenem·cilastatin sodium. Because the exudate exhibited M. hominis growth in an anaerobic environment, we administered the quinolone ciprofloxacin. This therapy resolved her fever, and her white blood cell count and C-reactive protein level diminished to the normal ranges. To our knowledge, there are four published articles regarding the isolation of M. hominis from postcesarean incisions. Based on the current study and the literature, infection by this pathogen may cause hematoma formation with or without abscess after cesarean section or in immunosuppressed postoperative patients. In such cases, physicians may need to suspect Mycoplasma infection and initiate appropriate antibacterial treatment as soon as possible in order to avoid persistent fever. PMID:21339933

    Full Text Available Construction delays are common problems in civil engineering projects in Egypt. These problems occur frequently during project life-time leading to disputes and litigation. Therefore, it is essential to study and analyze causes of construction delays. This research presents a list of construction delay causes retrieved from literature. The feedback of construction experts was obtained through interviews. Subsequently, a questionnaire survey was prepared. The questionnaire survey was distributed to thirty-three construction experts who represent owners, consultants, and contractor’s organizations. Frequency Index, Severity Index, and Importance Index are calculated and according to the highest values of them the top ten delay causes of construction projects in Egypt are determined. A case study is analyzed and compared to the most important delay causes in the research. Statistical analysis is carried out using analysis of variance ANOVA method to test delay causes, obtained from the survey. The test results reveal good correlation between groups while there is significant difference between them for some delay causes and finally roadmap for prioritizing delay causes groups is presented.

    We reported a case of compression of the ostium of left main coronary artery caused by aortic root intramural hematoma after blunt thoracic trauma treated with percutaneous coronary intervention (PCI). A 46-year-old man visited our hospital because of exertional chest discomfort and dyspnea for 4 months. He was diagnosed as compression of the ostium of left main coronary artery caused by aortic root intramural hematoma, severe stenosis in the ostium of the left main coronary artery. The percutaneous coronary intervention was conducted, and a drug-eluting stent was implanted successfully. The symptoms were improved and the patient had a good recovery after PCI surgery.

    Vertebroplasty (VP) is a well-known therapeutic modality used to treat pain associated with vertebral compression fractures. Major complications such as cord or root compression, epidural and subdural hematomas (SDH) and pulmonary emboli, occur in less than 1% of patients who undergo VP after compression fracture. Spinal SDH is an extremely rare complication that usually happens a few hours after the procedure. We report a case of spinal SDH that developed at two weeks after a successful VP. ...

    Full Text Available Neonatal asymptomatic suprarrenal hemorrhage is relatively frequent; sometimes it is detected only after resolution when a calcification is found; symptomatic forms are rare; most times hemorrhage and hematoma are due to an obstetric trauma and are related to macrosomia, breech presentation, maternal diabetes and neonatal hypoxia. Clinical picture is characterized by abdominal mass and anemia; diagnosis is confirmed by imagenology. Two patients with suprarrenal hematoma from the University Hospital at Cartagena, Colombia, are presented. Both were related with traumatic delivery and cephalohematoma; one of them had oral and gastric bleeding and the othersuffered hematoma infection; diagnosis was done with abdominal ecography and CAT. Both patients recovered with medical treatment. La hemorragia suprarrenal asintomática del neonato es relativamente frecuente y muchas veces se detecta como una calcificación local después de que se resuelve el hematoma. La forma sintomática es rara y, a menudo, se debe a un trauma obstétrico relacionado con la macrosomía fetal, la presentación podálica, la diabetes materna o la hipoxia perinatal. Las manifestaciones clínicas son, principalmente, una masa abdominal y anemia importante; el diagnóstico se confirma con la imaginología. Se presentan dos casos de hematoma suprarrenal derecho tratados en el Hospital Universitario de Cartagena, ambos relacionados con un parto traumático y acompañados de cefalohematomas; uno de ellos presentó sangrado gastrointestinal alto y el otro infección del hematoma suprarrenal. El diagnóstico se comprobó con la ecografía abdominal y se verificó con la tomografía. El tratamiento fue médico y no se requirió cirugía a pesar de la anemia severa que presentó uno de los pacientes.

  12. Drug interaction as cause of spontaneously resolving epidural spinal hematoma on warfarin therapy

    Full Text Available We present a case of a 42-year-old male, an old case of deep vein thrombosis on warfarin and other drugs like quetiapine, aspirin, diclofenac sodium, fenofibrate, atorvastatin, propanolol and citalopram for concurrent illnesses, who presented with widespread mucocutaneous bleeding and epidural spinal hematoma. The epidural bleed presented clinically as a nontraumatic, rapidly improving myeloradiculopathy. Magnetic resonance imaging (MRI of the spine revealed an epidural hematoma at D12-L1 level. The case was managed conservatively due lack of neurosurgical facilities. The patient gained full neurological recovery on conservative management alone. This case highlights the problem of drug interaction on warfarin therapy and also an unusual spontaneous recovery of spinal hematoma. Our case was anticoagulated in the recommended therapeutic INR range of 2.2 to 2.4. Most of the similar cases reported in literature were also anticoagulated in the therapeutic range. Thus intraspinal hemorrhage is a rare but dangerous complication of anticoagulant therapy. It must be suspected in any patient on anticoagulant agents who complains of local or referred spinal pain associated with neurological deficits. Drug interactions with warfarin are common. High suspicion and immediate intervention are essential to prevent complications from intraspinal hemorrhage.

    When roadworks are performed, one of the impacts is delays in the traffic. Partly because of reduced speed limits past the work zones but mainly because of the facility's limited quality of service. This could result in significant delays for the road users with lost work and spare time as a consequence. The lost time in congestions could have been used more efficiently. It is therefore of interest to estimate these delays for different types of roadworks to calculate its macro economical imp...

  18. Causes of delay in road construction projects in Malawi

    Scientific Electronic Library Online (English)

    M J, Kamanga; W J v d M, Steyn.

    Full Text Available A study was conducted to identify the causes of delay in completing road construction projects in Malawi. A literature review was done which yielded 72 typical causes of delay, and a questionnaire was sent to client, contractor and consultant representatives in Malawi. The results were analysed usin [...] g the Relative Importance Index (RII) and Spearman's Rank Correlation Coefficients, which indicated that the top ten causes of delay in Malawi are: shortage of fuel, insufficient contractor cash-flow, shortage of foreign currency for importation of materials and equipment, slow payment procedures adopted by the client in making progress payments, insufficient equipment, delay in relocating utilities, shortage of construction materials, delay in paying compensation to land owners, shortage of technical personnel, and delay in site mobilisation. The causes of delay are significant and should be given attention by client organisations, consultants and contractors to enable the timely completion of projects in future. It should also be noted that most of the causes of delay are not unique to Malawi, and have been observed in other southern African countries such as South Africa, Botswana and Swaziland. Recommendations are made to prevent similar causes of delay in future.

    Full Text Available Project delays in the construction industry are a universal or large-scale observable fact affecting not only the construction industry but the overall economy of countries as well. As far as the Malaysian construction industry is concerned, project delays are common problems in the construction industry, particularly in housing development. The objective of this study is to evaluate and identify the causes and the consequences of project delays in private housing development projects in Malaysia, and the remedies that can minimize these delays. The top ten causes of delays are weather conditions, poor site conditions, poor site management, incomplete documents, lack of experience, financial problems, contract modifications, delay in the approval of major variations, contractor coordination problems with other parties, and construction mistakes and defective works. It has been analysed that the causes of the delays point to the contractor factors, which contribute to the major factors that cause project delays in private housing development projects. The consequences of the delays include time overrun, cost overrun, differences in opinion, negotiations, legal actions and total abandonment. Herewith are presented some recommendations to minimize these project delays.

    The authors describe the case of an intramural duodenal haematoma caused a high ileus after a seven-day post-traumatic interval. The authors recommend surgical revision, in particular in children because the mechanism of injury is the same in intramural haematoma and in duodenal perforation. Only thus it is possible to prevena a fatal course, while the operation is easy and healing after drainage of the haematoma is rapid. PMID:2749389

  5. Transcatheter Embolization for Delayed Hemorrhage Caused by Blunt Splenic Trauma

    International Nuclear Information System (INIS)

    Although the exact benefit of adjunctive splenic artery embolization (SAE) in the nonoperative management (NOM) of patients with blunt splenic trauma has been debated, the role of transcatheter embolization in delayed splenic hemorrhage is rarely addressed. The purpose of this study was to evaluate the effectiveness of SAE in the management of patients who presented at least 3 days after initial splenic trauma with delayed hemorrhage. During a 24-month period 4 patients (all male; ages 19-49 years) presented with acute onset of pain 5-70 days after blunt trauma to the left upper quadrant. Two had known splenic injuries that had been managed nonoperatively. All had computed axial tomography evidence of active splenic hemorrhage or false aneurysm on representation. All underwent successful SAE. Follow-up ranged from 28 to 370 days. These cases and a review of the literature indicate that SAE is safe and effective for NOM failure caused by delayed manifestations of splenic arterial injury.

  7. Nuclear power plant delays: probable causes and resolutions

    International Nuclear Information System (INIS)

    The nuclear power industry in the United States is experiencing technological as well as construction and operation problems in nuclear facilities. Delays in completing many of the present-day nuclear power plants under construction have been an acutely felt problem in recent years. For example, Long Island Lighting Company's (LILCO's) Shoreham Plant is 10 years behind schedule; the delay in Consumers Power Company's Midland plant in Michigan was 9 years at the time the project was cancelled. Delays and repairs have led to cost overruns of significant magnitudes. A study released by the energy information administration of the Department of Energy showed that 36 of the 47 nuclear plants surveyed cost at least twice as much as initially projected, while 13 of them were four times higher. An extreme example is LILCO's Shoreham Plant. This plant is expected to be completed at a cost of $4 billion, or 15 times the original estimates. It is the intent of this paper to review past research done on the factors that cause these delays, to indicate their relative importance and impact on the nuclear industry, and to describe possible resolutions that are either currently being implemented or that have been proposed for future use

    Despite an overall advancement in breeding area arrival, one of the latest spring arrivals in northwest Europe since 1950 of several trans-Saharan songbird species occurred in 2011. Year-round tracking of red-backed shrikes and thrush nightingales revealed that the cause of the delay was a prolongation of stopover time during spring migration at the Horn of Africa, which was affected by extreme drought. Our results help to establish a direct link at the individual level between changes in local climate during migration and arrival and breeding condition in Europe thousands of kilometers further north.

    Subdural hematoma may occur as rare, although intervention- specific complications of accidental dural puncture by neuroaxial block. Bleeding may be caused by rapid cerebrospinal fluid loss related to traction on fragile intracranial bridging veins. This article reports a case of postdural puncture headache in a 43-year-old woman after accidental dural puncture during attempted placement of an epidural catheter for induction of abortion. Bed rest, analgesics, theophylline and hydration were to no avail and only a blood patch improved the headaches. The patient presented 7 weeks later with headache and left-sided hemiplegia. Magnetic resonance imaging showed a right frontoparietal subdural intracranial hematoma which had to be surgically evacuated. The patient recovered completely. Intracranial hematoma is a rare but serious complication of central neuroaxial block. According to current German jurisdiction this risk must be addressed when informed consent is obtained. Intracranial hematoma should be considered in the differential diagnosis of atypical headache and neurological signs (e.g. focal motor and sensory deficits and seizures) following neuroaxial block and adequate image diagnostics should be carried out without delay.

Many researchers seeking the causes of delay in order to reduce the probability of delay to occur. Most researcher identified causes of delay in construction to reduce the possibility of construction project to continued delay. This study is to obtain the holistic delay categories base on Drewin Open Conversion System (DOCS for the development of a theoretical framework delay and to get the most significant causes of delay in construction industries. There are three main factor of construction delay based on DOCS; input factor, internal factor and external factor. There are130 items on causes of delay and it is divided into 31 categories. This pilot survey is distributed to students and fresh graduates that have educational background in construction. The result shown the main factor that contributes to construction delay are mistakes during construction and unrealistic project durations.

    Study Design?Case report. Objective?To report the first case of ligamentum flavum hematoma after cervical spine instrumentation 11 years after the index surgery. Methods?After performing bilateral C3 and C4 laminectomy, we observed a dark greenish discoloration over the ligamentum flavum, which was opened. We evacuated 15 mL of subacute hematoma. Results?The first ligamentum flavum hematoma of the cervical spine that occurred after spinal instrumentation with sublaminar hooks. Conclusion?Ligamentum flavum hematoma might happen even after a long delay (in our case, 11 years) from spinal instrumentation (sublaminar hooks). In symptomatic patients, evacuation is the treatment of choice. In cases of instrument adhesion to the surrounding intracanal tissues, removal should be done meticulously after performing a complete release. PMID:26835213

    In summer 1981, the Federal Minister for Research and Technology ordered an ''investigation on the causes of cost increases and delays in the construction of SNR-300'' from a working team in Switzerland, in connection with the increase from 3.7 billion to 5 billion DM in the project costs for the fast breeder-prototype-nuclear power plant SNR 300. In June 1982, the Federal Ministry extended the order to DM 6.05 billion, the cost estimate by operators and producers which had been increased meanwhile and the new date for commissioning in July 1982. The investigation presented by the Fed. Min. for Research and Technology on 21. Sept. 82 analyses the causes, reviews the present project plants, also as compared with projects in other countries and contains, corresponding to the conclusions, recommendations for the remaining part of the project and, in addition to this, general recommendations for government-funded large research projects in the nuclear field. The article contains analyses and conclusions. (orig./UA)

    2004-01-01

    Full Text Available Background. Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma. Methods. Between 1980 and 2002, 28 patients with epidural hematoma of the posterior fossa were operated on at the Institute for Neurosurgery, Belgrade. Clinical course neuroradiological investigations, and the results of surgical treatment of the patients with posterior fossa epidural hematomas were analyzed retrospectively. Results. Almost two thirds of patients were younger than 16 years of age. In 20 cases injury was caused by a fall, in 6 cases by a traffic accident, and in 2 by the assault. Clinical course was subacute or chronic in two thirds of the patients. On the admission Glasgow Coma Scale was 7 or less in 9 injured, 8-14 in 14 injured, and 15 in 5 injured patients. Linear fracture of the occipital bone was radiographically evident in 19 patients, but was intraoperatively encountered in all the patients except for a 4-year old child. In 25 patients the diagnosis was established by computer assisted tomography (CAT and in 3 by vertebral angiography. All the patients were operated on via suboccipital craniotomy. Four injured patients who were preoperatively comatose were with lethal outcome. Postoperatively, 24 patients were with sufficient neurologic recovery. Conclusion. Posterior fossa epidural hematoma should be suspected in cases of occipital injury, consciousness disturbances, and occipital bone fracture. In such cases urgent CAT-scan is recommended. Early recognition early diagnosis, and prompt treatment are crucial for good neurological recovery after surgery.

    Full Text Available A construction project comprises of a number of work packages, which are subjected to delays. These delays may be caused by many on-site factors. The aim of this research is to represent owner and contractors perceptions towards delay factors that frequently occur in structural and finishing works. Data for analysis were gathered by distributing questionnaire. A total of 198 sets of questionnaire were gathered and used for subsequent analyses. In general, design changes during construction are perceived by respondents as the most frequent factor to cause delay in all structural and finishing works. The results also show that there are a number of differences between owner’s and contractor’s perceptions towards the occurrences of the factors. Whilst most contractors concern that information factors related to project design and scope frequently causing delays in construction works, owners consider many contractor originated factors, as most frequent delay causes.

    2013-01-01

    Supra- and infratentorial acute epidural hematoma (SIEDH) is a common type of posterior fossa epidural hematoma (PFEDH), representing 11- 64% of all PFEDHs. Although SIEDH is associated with typical characteristics, it might be difficult to diagnose when presenting as infratentorial acute epidural hematoma, which is clinically silent and has nonspecific symptoms. However, this type of hematoma can often be rapidly deteriorating, causing a sharp rise in intracranial pressure that leads to a life-threatening foramen magnum herniation. Early diagnosis and management of SIEDH are imperative. Traditional surgical management has always required relatively large craniotomies, larger than the hematoma itself, to expose its edge, and then tack up the dura matter). It usually opens the window and emphasizes retention of the bone bridge outside the transverse sinus. This method can effectively eliminate the hematoma, but it is associated with larger postoperative wound, longer operation time, larger skull defect, and more complications. Hence, exploration into a better surgical method is direly needed. PMID:23756966

A left frontal subdural hematoma with left putaminal hemorrhage was incidentally found when a CT scan was performed to evaluate right hemiparesis and aphasia in a 55-year-old man. The putaminal hemorrhage was not very extensive, but his clinical symptoms were rather serious. Not only the putaminal hemorrhage, but also the presence of the calcified subdural hematoma was considered to have caused his clinical deterioration. The subtotal removal of the calcified subdural hematoma brought about a good result.

  7. CT finding of right retroperitoneal space : analysis of extension of right perirenal hematoma

    International Nuclear Information System (INIS)

    To understand the structure and character of the right retroperitoneal space by analysis of the extension of retroperitoneal hematoma in patients with traumatic right renal injuries. We retrospectively reviewed CT scans of 13 patients with right retroperitoneal hematomas caused by right renal injury. At te renal level, we analyzed the relation of a hematoma contacting psoas muscle with other retroperitoneal compartmental hematomas. At the suprarenal level, a perirenal hematoma and a hematoma contacting the diaphragm were analyzed according to their relation with intrahepatic IVC and pericaval hematoma. Below renal hilar level, all hematomas contacting psoas muscle, observed in eight cases, were connected with retrorenal extension of anterior pararenal hematoma. At the suprarenal level, intrahepatic pericaval hematomas were not, in all 13 cases, connected with a hematoma contacting the diaphragm, but with a perirenal hematoma. At the upper suprarenal level, the only pericaval hematomas containing a medial component of perirenal hematoma extended superiorly to the upper one third of the tenth thoracic vertebral body. The anterior renal fascia envelops perirenal space except in its medial aspect. In the upper suprarenal region, the anterior and posterior planes of the anterior renal fascia unite to fuse with diaphragmatic fascia, but along the medial aspect they fuse with intrahepatic pericaval connective tissue and posteromedial diaphragm, respectively

  8. Sonographically Diagnosed Vault Hematomas Following Vaginal Hysterectomy and Its Correlation with Postoperative Morbidity

    Full Text Available Objective. Our aim is to investigate sonographically detectable vault hematomas after vaginal hysterectomy and its relation to postoperative morbidity. Methods. We studied a group of 103 women who had undergone vaginal hysterectomy for benign causes apart from uterovaginal prolapse. Transabdominal ultrasound examinations were carried out 24 to 72 hours after surgery to assess the presence of vault hematomas. Ultrasound findings were correlated with clinical data and postoperative morbidity. Results. The incidence of vault hematoma was found 19.4% in present study. In these patients, 40% (8/20 had fever while only 2.4% (2/83 of cases without vault hematoma suffered from fever. Out of all women having vault hematoma, 70% (14/20 had small-sized hematoma and 30% (6/20 had large-sized hematoma. Fifty percent of patients (3/6 with large-sized hematoma, as compared to only 35% (5/14 with small-sized hematoma, suffered from febrile morbidity. Large-sized hematomas drained by vaginally, while all small-sized pelvic hematomas managed by watchful expectancy successfully. The significant difference was found mean hemoglobin drop and postoperative stay in the hematoma group or without hematoma group. Conclusion. Sonographic detection of vaginal vault fluid collection is common after hysterectomy, but such a finding rarely indicates additional treatment. Though febrile morbidity was more in cases with vault hematoma, the number of such patients was too small to be significant. Vaginal ultrasound examination should not be performed routinely after hysterectomy.

  11. Project Management Patterns to Prevent Schedule Delay Caused by Requirement Elicitation

    Science.gov (United States)

    Hori, Shozo; Nakatani, Takako; Katamine, Keiichi; Ubayashi, Naoyasu; Hashimoto, Masaaki

    We propose PM (Project Management) patterns to prevent schedule delays caused by changes in requirements on empirical studies. Changes or late elicitation of requirements during the design, coding and test processes are one of the most serious risks, which may delay project schedules. However, changes and late elicitation of requirements are usually accepted during development processes. Therefore, the PM methods for preventing schedule delays caused by changes and late elicitation of requirements during development processes are an important area of study. In this study, we examined the actual conditions of various projects which succeeded in preventing schedule delays resulting from changes and late elicitation of requirements during development processes. We were able to extract various typical PM techniques for preventing these schedule delays. The techniques, known as “PM patterns”, were also applied to other projects. The patterns were arranged on a two-dimensional framework. We discuss a framework of PM patterns aimed at solving the problems caused by changes in requirements.

La cirugía supratentorial con pérdida abundante de LCR sería el factor más importante de esta complicación. El hiperdrenaje de LCR produce relajación del cerebelo con la consiguiente tracción y rotura de las venas puente que van a la tienda, provocando hematomas subdurales e infartos venosos hemorrágicos del cerebelo.

Case 1, 70 years old male, with a left hemiparesis and a lucid status after evacuation of subdural hematoma suffered a 2.5 cm bleeding in the cerebellar folias and in the vermis after 72 hs of the surgery. The evolution was unfavorable with a sudden neurological deficit and cardiorespiratory failure. Case 2, 40 years old female, with asymptomatic 1 cm vermian hematoma found in the CT scan control after 72 hs of the surgery. Evolution was without neurological deficit. Conlusion. Supratentorial surgery with considerable outflow of cerebrospinal fluid would be the one most important factor in this complication. The cerebrospinal overdrainage produces cerebellar relaxation with the consequent traction and rupture of the brinding veins toward the tentorium, generating subdural haematomas and cerebellar hemorragic venous infarction. These two cases reported were operated with non aspirative subdural drainages with considerable cerebrospinal outflow for 72 and 48 hs respectively, that is the common etiologic pattern according to most of the authors.

  13. Impact of early surgical evacuation of sylvian hematoma on clinical course and outcome after subarachnoid hemorrhage

    International Nuclear Information System (INIS)

    The present study aimed to evaluate the impact of early surgical evacuation of sylvian hematoma caused by ruptured middle cerebral artery (MCA) aneurysm on clinical outcome after subarachnoid hemorrhage. Hospital records and computed tomography scans for 26 patients with MCA aneurysm who underwent surgical clipping between June 2001 and January 2008 were retrospectively reviewed. All patients presented with sylvian hematoma associated with subarachnoid hemorrhage and received surgery at 7.9±3.6 (mean±standard deviation) hours of ictus. They were divided postoperatively into two groups, achievement (n=16) and non-achievement (n=10) of extensive hematoma evacuation, and their clinical course and functional outcomes were compared. The frequencies of delayed ischemic neurological deficit and vasospasm-related cerebral infarction were significantly less (p<0.05) in the achievement group. Better functional outcomes were obtained in patients with successful evacuation (p<0.05), as assessed by improvement of hemiparesis on manual muscle testing scale at postoperative 1-month follow up and by the modified Rankin scale at postoperative 3 and 6 months. Clinical outcomes were also better in the achievement group. These results suggest that better clinical course and outcome can be expected in patients who undergo early successful hematoma evacuation with surgical clipping of a ruptured MCA aneurysm. (author)

    To report a patient who presented with epithelial ingrowth caused by viral keratoconjunctivitis 3 months after LASIK surgery. A 41-year-old man presented with decreased visual acuity in the right eye, which had developed about 3 weeks before. He had undergone LASIK surgery 3 months prior without complications. Two months after the surgery, he was treated for viral conjunctivitis. During the treatment period, filamentary keratitis developed, and a therapeutic bandage contact lens was applied for 2 weeks. Upon presentation, examination revealed a corrected visual acuity of 20/100 and irregular epithelial sheets under the edematous flap. The flap was lifted, and the in-grown epithelium was removed. The flap was repositioned with double continuous 10 - 0 nylon sutures. Post-operatively, the patient developed a mild diffuse lamellar keratitis that resolved rapidly with topical corticosteroid treatment. At 2 months, the corrected visual acuity was 20/20 without interface opacities. As the patient showed no complications prior to viral conjunctivitis, we suspect that the viral infection caused edema of the corneal flap, which caused epithelial ingrowth under the flap. Patients who have viral conjunctivitis after LASIK surgery should be examined carefully and managed with consideration of flap complications. PMID:18729311

    Full Text Available There is an increase in the number of construction projects experiencing extensive delays leading to exceeding initial time and cost budget.  This paper reviews 41 studies around the world which surveyed the delay factors and classified them into Groups.  The main purpose of this paper is to review literature, each of which have categorized the causes that are responsible for time delays and cost overrun in projects. The collected list has 113 causes for delays categorized in to 18 different groups.  Most of the researches have analysed the responses from the Questionnaire survey.    The collected data are used to rank the problem.  The data are further used to investigate and analyse Important Index, Frequency Index, Severity Index, Relative Important Index, Relative Importance Weight, Weighted Average, Mean, Standard Deviation and Variance.  The collective comparison has revealed that the ranking given by all the researchers is not the same.  Further each and every study has different rank ratings for the different group of the delays.  This review paper attempts to provide an updated compilation of the earlier studies on ranking of the delay causers, which are never similar and constant for universal projects.  It is concluded that a separate study is required for identifying the factors causing delay for projects operated in Sabah, East Malaysia.

    Traumatic head injuries can cause internal bleeding within the brain. The resulting hematoma can elevate intracranial pressure, leading to complications and death if left untreated. A craniotomy may be required when conservative measures are ineffective. To augment conventional surgical training, a Virtual Reality-based intracranial hematoma simulator is being developed. A critical step in performing a craniotomy involves cutting burrholes in the skull. This paper describes volumetric-based haptic and visual algorithms developed to simulate burrhole creation for the simulator. The described algorithms make it possible to simulate several surgical tools typically used for a craniotomy. PMID:17377222

    The imaging studies and clinical findings in 10 patients who suffered delayed vision loss beginning 1 day to 13 years after head trauma have been reviewed. Two different primary lesions could be identified: pseudoaneurysm of the internal carotid artery and carotid cavernous fistula. The pathologic changes associated with pseudoaneurysm included compression of the optic nerves and/or chiasm by arterial aneurysm and intracranial hematoma. Carotid cavernous fistula caused delayed vision loss by compression of the optic nerves and chiasm by saccular dilatation of the cavernous sinus and by abnormal orbital venous drainage with retinal venous stasis, retinal edema, and glaucoma

    Full Text Available Time performance of a project is usually a particularly important consideration for the construction parties. Often, the most troublesome construction disputes involve delay and failure to complete the work in the specified time frame. Many variables have an impact upon construction delay in Saudi Arabia. This study aims at identifying the risk matrix for delay causes in construction projects in Saudi Arabia from consultants’ viewpoint. A questionnaire survey was undertaken of 51 consultants working on construction projects in the Northern Province of Saudi Arabia. Thirty five delay causes were identified through literature review. The study concluded that the top delay causes in construction projects in Saudi Arabia from consultants’ perspective are: bid award for lowest price, changes in material types and specifications during construction, contract management, duration of contract period, fluctuation of prices of materials, frequent changes in design, improper planning, inflationary pressure, lack of adequate manpower, long period between design and time of implementation, payments delay, poor labor productivity and rework.

    Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

El hígado se palpa a 3 cm debajo del reborde costal; Hemograma con eosinofilia severa. Se aprecia leve colestasis. Ecografía abdominal: Masa hepática heterogénea de 13 cm de diámetro en el lóbulo derecho. Tomografía axial computarizada: Masa subcapsular de 14x8 cm. Gammagrafía: Hígado con área hipocaptadora que muestra ausencia de perfusión al pool vascular. Se somete a laparotomía exploratoria y se encuentra hematoma subcapsular de 800 cc en segmento 6, 7 y 8, el cual se drena. En la evolución persite la eosinofilia y se obtiene Arco 2 positivo para Fasciola. Recibió triclabendazol, actualmente asintomática. Conclusión: La fase invasiva de la fasciolosis humana puede ocasionar hematoma hepático como una complicación rara. La triada de eosinofilia persistente, hepatomegalia dolorosa y fiebre prolongada, orienta a insistir en la búsqueda de fasciolasis en zonas endémicas. Abstract in english The case of a 22 year old woman from Huaraz is presented herein. She suffered from pain at right hypocondrium, associated to nausea and vomits, which intensified three days prior to admission. Upon examining her, a faded gallbladder murmur was found on the base of the right hemithorax. There is pain [...] in the abdomen when touched at the epigastrium and right hypocondrium. The liver is perceived 3 cm beneath the costal edge: White blood count with severe eosinophilia. Mild cholestasis is observed. Abdominal scan: Heterogeneous hepatic mass, with a 13 cm diameter in the right lobe. CAT scan: Subcapsular 14x8 cm mass. Scintiscan: Liver with a low absorption area showing absence of perfusion to the vascular pool. She undergoes an exploratory laparotomy and an 800 cc subcapsular hematoma is found in segment 6, 7 and 8, which is drained. Evolution evidences the persistence of eosinophilia and positive Arc-2 is obtained for Fasciola. She was administered Triclabendazol and is currently asymptomatic. Conclusion: The invasive stage of human fascioliasis may cause hepatic hematoma as a rare complication. The triad of persisting eosinophilia, painful hepatomegalia and prolonged fever leads to insist in the search of fascioliasis in endemic areas.

  6. Systemic 5-fluorouracil treatment causes a syndrome of delayed myelin destruction in the central nervous system

    Full Text Available Abstract Background Cancer treatment with a variety of chemotherapeutic agents often is associated with delayed adverse neurological consequences. Despite their clinical importance, almost nothing is known about the basis for such effects. It is not even known whether the occurrence of delayed adverse effects requires exposure to multiple chemotherapeutic agents, the presence of both chemotherapeutic agents and the body's own response to cancer, prolonged damage to the blood-brain barrier, inflammation or other such changes. Nor are there any animal models that could enable the study of this important problem. Results We found that clinically relevant concentrations of 5-fluorouracil (5-FU; a widely used chemotherapeutic agent were toxic for both central nervous system (CNS progenitor cells and non-dividing oligodendrocytes in vitro and in vivo. Short-term systemic administration of 5-FU caused both acute CNS damage and a syndrome of progressively worsening delayed damage to myelinated tracts of the CNS associated with altered transcriptional regulation in oligodendrocytes and extensive myelin pathology. Functional analysis also provided the first demonstration of delayed effects of chemotherapy on the latency of impulse conduction in the auditory system, offering the possibility of non-invasive analysis of myelin damage associated with cancer treatment. Conclusions Our studies demonstrate that systemic treatment with a single chemotherapeutic agent, 5-FU, is sufficient to cause a syndrome of delayed CNS damage and provide the first animal model of delayed damage to white-matter tracts of individuals treated with systemic chemotherapy. Unlike that caused by local irradiation, the degeneration caused by 5-FU treatment did not correlate with either chronic inflammation or extensive vascular damage and appears to represent a new class of delayed degenerative damage in the CNS.

  7. Acute epidural hematoma in children

    International Nuclear Information System (INIS)

    The clinical features and sequential changes of CT findings in children with acute epidural hematoma were correlated with the patient's age. Of the 373 children admitted for head injury during the past 8 years, 61 had an acute traumatic intra-cranial hematoma, and 38 of these had acute epidural hematoma. None of the patients with acute epidural hematoma was under 2 years of age, 15 were 2-6 years old, and 23 were 7-15 years old. In the pre-school group, the numbers of boys and girls were approximately equal, but in the older group boys outnumbered girls. Epidural hematoma was most often parietal (12 patients). Nine patients had posterior fossa hematomas; 30 (78.9%) had skull fractures, and the incidence was not related to the patient's age. In 28 of the 38 patients, CT scans were examined repeatedly for 24 hours. In 15 of them (53.6%), the size of the hematoma increased. In school-aged children, the hematoma tended to be larger than in pre-school children. In four patients with pneumocephalus, the hematoma increased in size. Eleven of the 13, whose hematomas did not increase in size, had skull fractures. (author)

    Full Text Available ABSTRACTIn Latin America, Bothrops envenomation is responsible for the majority of accidents caused by venomous snakes. Patients usually present local edema, bleeding and coagulopathy. Visceral hemorrhage is extremely rare and considered a challenge for diagnosis and management. We report the first case of hepatic hematoma owing to the bothropic envenomation in a 66-year-old man who was bitten in the left leg. He presented local edema, coagulopathy, and acute kidney injury. Radiological findings suggested hepatic hematoma, with a volume of almost 3 liters. The hepatic hematoma was gradually absorbed without the need for surgical intervention with complete resolution in 8 months.

  9. Causes and remedial measures for construction delays: a case study of pakistan

    International Nuclear Information System (INIS)

    Delays are the most common event that influence the time performance and increase the cost of projects. This paper analyze causes of various delays experienced by three large construction projects in public sector and subsequently to recommend the corrective actions necessitated to safeguard future construction projects from suffering these delays, which result in enormous cost and time over-runs, undermining projects economic viability. The case-study approach has been employed as research method, to analyze construction delays, followed by categorizing them in view of their source. The method employed to collect data included interviews, questionnaire surveys, and analysis of project documents including monthly progress reports, minutes of meeting, and details of correspondence held between the project participants. The data collected was minutely analyzed to identify different delays, and their underlying causes encountered during execution of projects. The analysis reveals serious lapses on part of projects planners, for their failure to take care of the inevitable contingencies (unexpected situations), while conceptualizing projects by resorting to proactive planning at the very outset, incorporating adequate buffers in the projects budgeted costs, and timeframes, to ensure projects economic viability in any eventuality. The failure of owners to establish key performance indicators, followed by their inability in tracking down the indicators, worsened the situation, resulting in projects execution lagging far behind original schedules of construction activities with their estimated costs.

    2015-10-01

    Full Text Available Background/ objectives: Post-thyroidectomy hematoma is a rare but fatal complication of thyroidectomy. The incidence of hematoma has dropped to less than 2-3% due to better preoperative preparation & major refinements in surgical techniques. Setting: Department of ENT, Head & Neck Sur-gery, KVG Medical College, Sullia. Case report: We report a case of post- thyroidectomy hematoma in an elective surgery done for a large thyroid. The hematoma occurred 15 minutes after surgery & was managed success-fully under general anaesthesia. Intervention: Urgent evacuation of the hematoma was done under general anaesthesia & bleeders were re-ligated. 2 pints of A+ blood was transfused. Conclusion: Post-thyroidectomy hematoma leading to airway obstruction is a fatal complication which needs emergency management. Post-operative care include attention to the drain, careful monitoring in the recovery room & appreciation of subtle signs of respiratory distress. So every thyroidectomy case can bleed & cause hematoma complication. Prevention & early intervention can avoid fatal complications.

  11. The Carrier's Liability for Damage Caused by Delay in International Air Transport

    Science.gov (United States)

    Lee, Kang Bin

    2003-01-01

    Delay in the air transport occurs when passengers, baggage or cargo do not arrive at their destination at the time indicated in the contract of carriage. The causes of delay in the carriage of passengers are booking errors or double booking, delayed departure of aircraft, incorrect information regarding the time of departure, failure to land at the scheduled destination and changes in flight schedule or addition of extra landing stops. Delay in the carriage of baggage or cargo may have different causes: no reservation, lack of space, failure to load the baggage or cargo at the right place, or to deliver the covering documents at the right place. The Montreal Convention of 1999 Article 19 provides that 'The carrier is liable for damage occasioned by delay in the carriage by air of passengers, baggage or cargo. Nevertheless, the carder shall not be liable for damage occasioned by delay if it proves that it and its servants and agents took all measures that could reasonably be required to avoid the damage or that it was impossible for it or them to take such measures'. The Montreal Convention Article 22 provides liability limits of the carrier in case of delay for passengers and their baggage and for cargo. In the carriage of persons, the liability of the carrier for each passenger is limited to 4,150 SDR. In the carriage of baggage, the liability of the carrier is limited to 1,000 SDR for each passenger unless a special declaration as to the value of the baggage has been made. In the carriage of cargo, the liability of the carrier is limited to 17 SDR per kilogram unless a special declaration as to the value of the cargo has been made. The Montreal Convention Article 19 has shortcomings: it is silent on the duration of the liability for carriage,andit does not make any distinction between persons and good. It does not give any indication concerning the circumstances to be taken into account in cases of delay, and about the length of delay. In conclusion, it is desirable to define the period of carriage with accuracy, and to insert the word 'unreasonable' in Article 19.

    Full Text Available The most common complication of spinal anesthesia is postdural puncture headache. Any injury of the dura may cause headache. After the injury of the dura, CSF leakage may occur and due to the tension of the veins between the cortex and the dural sinuses, subdural hematoma may be seen. Herein, we present a patient with persistent headache after the spinal anesthesia given during delivery of her baby, and emphasize a rare complication of spinal anesthesia which is subdural hematoma.

  14. An Induced Hematoma in Caudoputamen Nuclei in Rats Causes Central Pain when the Thalamus is also Implicated and the Central Sensitization is Reversed with Gabapentin

    Full Text Available Problem statement: The objective of this study was to evaluate pain sensitisation in rats following the induction of an intracerebral hemorrhage by injecting a collagenase solution in the caudoputamen nucleus of the right basal ganglia and to evaluate gabapentin as an analgesic for central pain. Approach: Thirty male Sprague-Dawley rats weighing between 175-300 g were used. In a first experiment, 3 groups of 6 animals were used to evaluate pain threshold using the Hargreaves test (thermal sensitivity only. Following 3 days of behavioral testing (baseline values, animals in each group were injected intracerebrally either with 0.5, 1 or 2 ?L of a collagenase solution (0.5 U 2 ?L-1 Type VII collagenase inducing a hematoma in the right caudoputamen nucleus and/or thalamus. They were then tested for the next 9 consecutive days. In a second experiment, gabapentin was evaluated for the reversal of thermal hyperalgesia and mechanical allodynia (using von Frey filaments following the intracerebral injection of 3 ?L of the collagenase solution. Results: No pain-related behavioral changes were observed following injections with 0.5 and 1 ?L of the collagenase solution. However with 2 ?L, reaction times were significantly faster on days 3-7 in the right and left hind paws compared to baseline values. The lesion was localized only in the caudoputamen nucleus for animals receiving 0.5 and 1 ?L of collagenase whereas lesions extended in the ipsilateral thalamic nuclei (lateral-dorsal and lateral-posterior nuclei for animals receiving 2 ?L of collagenase. Gabapentin reversed mechanical allodynia and thermal hyperalgesia in animals with caudoputamen and thalamic lesions. Conclusion: These preliminary results suggest that central pain was induced in rats with a collagenase-induced intracerebral hemorrhage localized in the thalamus and that mechanical allodynia and thermal hyperalgesia were reduced with gabapentin treatment.

  17. Spontaneous epidural hematoma at lumbar facet joint: a case report

    International Nuclear Information System (INIS)

    Spontaneous epidural hematomas (SEHs) of the lumbar spine are rare. The pathogenesis is not entirely clear, but several reports have suggested that bleeding originating in the venous epidural plexus is the cause. This is the second report of a SEH thought to be the result of facet joint hemorrhage with no previous synovial cyst formation. A magnetic resonance image revealed a mass beginning in the left epidural space and continuing through to the left L5-S1 facet joint. Surgically, the epidural hematoma, which was covered by a very thin translucent membrane, was visualized directly. A histopathological examination revealed the wall of the epidural hematoma to be composed of very thin fibrous connective tissue with no synovium lining. The purpose of this study was to report a case of an epidural hematoma originated from lumbar facet joint, diagnosed by radiological examination, and to present a review of the subject literature

    Dissipation may cause two initially entangled qubits to evolve into a separable state in a finite time. This behavior is called entanglement sudden death (ESD). We study to what extent quantum error correction can combat ESD. We find that in some cases quantum error correction can delay entanglement sudden death but in other cases quantum error correction may cause ESD for states that otherwise do not suffer from it. Our analysis also shows that fidelity may not be the best measure to compare the efficiency of different error correction codes since the fidelity is not directly coupled to a state’s remaining entanglement.

    2009-09-01

    Full Text Available An iliopsoas hematoma can occur either spontaneously or secondary to trauma or bleeding tendency due to hemophilia and anticoagulant therapy. Although liver cirrhosis is commonly associated with coagulopathy, iliopsoas hematoma is very rare. We herein, present a case of bilateral iliopsoas hematoma in a patient with alcoholic cirrhosis, and review the literature on muscle hematoma associated with cirrhosis. A 56-year-old man with alcoholic cirrhosis was admitted in a state of shock with anemia. The cause of anemia could not be detected, and the patient was treated conservatively. The site of bleeding was not detected with either gastroduodenal endoscopy or upper abdominal computed tomography, the latter of which did not include the iliopsoas muscle. He died on the 10th day of admission and bilateral iliopsoas hematomas were found on autopsy. An iron stain was positive in the iliopsoas muscle. Eight cases of muscle hematoma associated with cirrhosis, including the present case, were found in a review of the literature. Four of these cases involved the rectus abdominis muscle, 3 involved the iliopsoas muscle and 1 involved combined muscles. Alcoholic cirrhosis accounted for 75% of the cases. One case (12.5% was associated with virus-related cirrhosis, and another with combined virus- and alcohol-related cirrhosis. The mortality rate was 75% despite early diagnosis and low risk scores for cirrhosis. Muscle hematoma in patients with cirrhosis is closely related to alcoholism, and the mortality rate of the condition is extremely high. In conclusion, muscle hematoma should be recognized as an important complication of cirrhosis.

  2. MRI evaluation of postoperative epidural hematoma after lumbar spine surgery

    International Nuclear Information System (INIS)

    Pain or numbness in the lower extremities often persists after lumbar spine surgery and it is not rare for such symptoms to occur anew. We performed a retrospective comparative study in 66 cases to determine whether there were differences in post-operative symptoms based on the presence of an epidural hematoma diagnosed by postoperative MRI. An epidural hematoma was identified in 30 of the cases, but not in the other 36 cases. The incidence of buttocks pain was 40.0% in the epidural hematoma group (EH group), as opposed to 16.7% among those without an epidural hematoma (non-EH group), and the difference between the two groups was significant (P=0.034). The incidence of pain in the lower extremities was 40.0% in the EH group, as opposed to 16.7% in the non-EH group, and the difference between the two groups was significant (P=0.034). However, there were no difference between the groups in low back pain, lower extremity numbness, presence of muscular weakness, or rate of improvement in Japanese Orthopedic Association (JOA) score. All of the postoperative hematomas resolved spontaneously. The result of the study showed that some epidural hematomas cause postoperative symptoms to persist and make the short-term outcome unsatisfactory even through the long-term results are ultimately satisfactory.

    Spinal anesthesia is widely used for many obstetric, gynecological, orthopedic, and urological operations. Subdural hematomas may occur after trauma and are associated with high morbidity and mortality rates. Postdural puncture headache (PDPH) is a benign condition and the most frequent complication of spinal anesthesia. The high rate of headache after spinal anesthesia may mask or delay the diagnosis of subdural hematoma. The true incidence of postdural puncture subdural hematoma (PDPSH) is unknown because most affected patients are probably managed without investigation. Therefore, the true incidence of PDPSH may be greater than suggested by previous reports. The differentiation of headache associated with subdural hematoma from PDPH is crucial. We herein report two cases of bilateral subdural hematoma after epidural anesthesia and emphasize the importance of suspicion for PDPSH and careful evaluation of patients with headache after spinal anesthesia.

It is poorly represented in the literature. Current evidence attributes it to orbital trauma, neoplasm, vascular malformations, acute sinusitis, and systemic abnormalities. A 65-year-old female presented with spontaneous intraorbital hematoma manifesting as severe ocular pains, eyelid edema, proptosis, and diplopia, without a history of trauma. Computer tomography demonstrated a fairly well defined extraconal lesion with opacification of the paranasal sinuses. The principal differential based on all findings was that of a spreading sinus infection and an extraconal tumor. An unprecedented finding of a spontaneous orbital hematoma was discovered when the patient was taken to theater. We discuss the rarity of this condition and its management.Keywords: hemorrhage, ophthalmology, spontaneous, intra-orbital, hematoma

    The appearance of subcapsular liver hematoma after a laparoscopic cholecystectomy (LC) is an infrequent complication and seldom studied. Some cases have been connected to ketorolac given during surgery and after surgery. Other described causes are : hemangiomas or small iatrogenic lesions that could be aggravated by administration of ketorolac. Coagulation dysfunction like circulating heparin as seen in hemathological diseases is cause of bleeding after aggressive procedures. We describe two cases of subcapsular liver hematoma after LC, both of them have been given intravenous ketorolac and one of them had multiple myeloma. We discuss the causes and treatment of it.

    Full Text Available Alterations in blood clotting are a frequent complication of serious heatstroke and may result in gastrointestinal bleeding. We report the case of a 26-year-old man who was admitted to our hospital with symptoms of hyperthermia associated with encephalopathy and disseminated intravascular coagulation (DIC after prolonged exposure to sunlight. He presented hematemesis, after which he was diagnosed with having a bruising of the esophagus that took up the upper and lower thirds, there being no other lesions in the stomach or duodenum. After supportive treatment and following the resolution of the underlying pathology, the endoscopy-revealed injuries healed with a complete normalization of the esophageal mucosa. Esophageal submucosal bruising is an exceptional cause of hematemesis in serious heatstroke not previously described in the literature.Las alteraciones de la coagulación son una complicación frecuente en el golpe de calor grave, y pueden ser causa de hemorragia digestiva. Presentamos el caso de un varón de 26 años que fue admitido en nuestro hospital por un cuadro de hipertermia, asociado con encefalopatía y coagulación intravascular diseminada tras exposición solar prolongada. Presentó hematemesis por la que fue diagnosticado de múltiples hematomas esofágicos que ocupaban los tercios superior e inferior del órgano, en ausencia de otras lesiones en estómago y duodeno. Tras el tratamiento de soporte y la resolución de la patología subyacente, desaparecieron las lesiones endoscópicas, normalizándose la mucosa esofágica.

    Early diagnosis of intracranial hematomas is necessary to improve outcome in patients with traumatic brain injury (TBI). CT and MRI can diagnose intracranial hematomas, but cannot be used until the patient arrives at a major healthcare facility, resulting in delayed diagnosis. Near infrared spectroscopy may suggest the presence of unilateral intracranial hematomas, but provides minimal information on hematoma type and location due to limitations associated with strong light scattering. We have used optoacoustics (which combines high endogenous optical contrast with the resolution of ultrasound) to diagnose hematomas and monitor cerebral oxygenation. We performed animal and clinical studies on detection and characterization of hematomas and on monitoring cerebral hypoxia by probing the superior sagittal sinus (SSS). Recently, we built a medical grade, multi-wavelength, OPO-based optoacoustic system tunable in the near infrared spectral range. We developed new patient interfaces for noninvasive, transcranial measurements in the transmission mode in the presence of dense hair and used it in patients with TBI. The optoacoustic system was capable of detecting and characterizing intra- and extracranial hematomas. SSS blood oxygenation was measured as well with the new interface. The obtained results indicate that the optoacoustic system in the transmission mode provides detection and characterization of hematomas in TBI patients, as well as cerebral venous blood oxygenation monitoring. The transmission mode approach can be used for optoacoustic brain imaging, tomography, and mapping in humans.

  11. Patient delay is the main cause of treatment delay in acute limb ischemia: an investigation of pre- and in-hospital time delay

    DEFF Research Database (Denmark)

    Londero, Louise Skovgaard; NØrgaard, Birgitte

    2014-01-01

    Abstract BACKGROUND: The prognosis of acute limb ischemia is severe, with amputation rates of up to 25% and in-hospital mortality of 9-15%. Delay in treatment increases the risk of major amputation and may be present at different stages, including patient delay, doctors´ delay and waiting time in the emergency department. It is important to identify existing problems in order to reduce time delay. The aim of this study was to collect data for patients with acute limb ischemia and to evaluate the time delay between the different events from onset of symptoms to specialist evaluation and further treatment with focus on pre-hospital and in-hospital time delays. METHODS: We conducted a prospective cross-sectional cohort study including all patients suspected with acute limb ischemia who were admitted to the emergency department of a community hospital in a six months period. Temporal delay in the different phases between the time of occurrence of symptoms and completion of treatment was recorded prospectively. All patients who underwent intervention had a 30 days follow-up with regard to major amputation of the leg and survival. RESULTS: A total of 42 patients (21 men and 21 women) age 73 (20-95) years (median (range)) was identified. From onset of symptoms to first contact with a doctor the time for all patients were 24 (0-1200) hours. Thirty patients needed immediate intervention. In the group of fourteen patients who had immediate operation, the median time from vascular evaluation to revascularization was 324.5 (122-873) minutes and in the group of eight patients that went through an imaging procedure before an operation the median delay was 822 (494-1185) minutes from specialist assessment to revascularization. The median time for revascularization among four patients, who were treated with arterial thrombolysis was 5621 (1686-8376) minutes. At 30 days follow up, six patients had had the ischemic limb amputated above the ankle and four patients had died. CONCLUSIONS: We found that the largest time delay was between onset of symptoms and first contact to a medical doctor. A greater public awareness is needed, so as to facilitate urgent revascularisation and improve outcomes.

    Spontaneous spinal subdural hematoma is a rare disease. Several predisposing factors are reported including impaired clotting due to therapeutic anti-coagulation or hematologic disorder, vascular anom-aly, intraspinal tumor, and iatrogenic causes such as lumbar puncture or spinal anesthesia.We report a rare case of spontaneous spinal subdural hematoma developed after weightlifting in a healthy young man treated with conservative treatment.

  14. Large Intraluminal Ileal Hematoma Presenting as Small Bowel Obstruction in a Child

    International Nuclear Information System (INIS)

    Intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. We present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. Computed Tomography (CT) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. Abdominal ultrasonography (US) showed an echogenic mass-like lesion with multiple septa in the distal ileum. Small bowel obstruction due to a complicated cystic mass was provisionally diagnosed. Histopathologic examination of the resected mass suggested a submucosal ileal hematoma. Although intraluminal small bowel hematoma is rare in children, it can present as an intraluminal cystic mass and should be considered as a rare cause of small bowel obstruction. The US and CT findings of submucosal ileal hematoma could be useful for the diagnosis of such cases in the future

    A 14-year-old girl presented with a rare case of spontaneous bilateral supratentorial epidural hematomas which developed rapidly following cervical surgery. The hematomas presumably resulted from dural dynamics changes secondary to cerebrospinal fluid loss and intracranial hypotension. Intracranial epidural hemorrhage after spinal surgery is extremely uncommon with only one previous case report. Spontaneous intracranial epidural hematoma is an extremely rare complication, but should be considered as a possible complication of spine surgery, especially in adolescents complicated by delayed consciousness and breathing restoration from anesthesia. This case report expands the presently known clinical spectrum of this uncommon complication. PMID:23006878

    Full Text Available Project delay in the construction industry is a universal or large-scale observable fact affecting not only the construction industry but the overall economy of countries too. The objective of this study is to evaluate and identify the causes and consequences of project delays in the private housing development projects in Malaysia and the remedies that can minimize these delays. An online questionnaire survey has been carried out to collect the data and this included 76 respondents from multiple developers’ companies around Malaysia. From the survey, a total of 28 causes and 6 consequences of project delays had been identified from four different factors of delays; such as client factors, consultant factors, contractor factors and external factors, by which the contractor factor being the major contributor to this problem.The top ten causes of the delays are due to weather conditions, poor site conditions, poor site management, incomplete documents, lack of experience, financial problems, contract modifications, delay in approving of major variations, contractor coordination problem with other parties and construction mistakes and defective works. The consequences of the delays would contribute to time overrun, cost overrun, different in opinions, negotiations, legal actions and total abandonment.

  18. Pathogenesis of chronic subdural hematoma

    International Nuclear Information System (INIS)

    Ten cases of chronic subdural hematoma that were followed by a sequential study with CT from an early posttraumatic period to evolution of chronic subdural hematoma were reported. In four of these 10 cases, the initial CT showed thin subdural collections of high density suggesting acute subdural hematoma. Two weeks later, the density of subdural collections reduced, but their volumes increased. Clinical symptoms such as headache and disorientation occurred three or four weeks later. Preoperative CT showed similar huge subdural collections of low density and marked mass effect. These cases underwent surgery from 24 to 44 days after injury, and development of neomenbranes was confirmed. In the remaining six cases, the initial CT showed thin subdural collections of low density suggesting subdural hygroma. In five of the six cases, the density of the subdural collections was slightly higher than that of cerebrospinal fluid, and in one case, an area of spotted high density was shown. It was suggested that these were mixtures with blood. Follow-up CT scans revealed that the subdural collections increased in size but remained at a uniformly low density for the first month after the head injury, and then the increase in density occurred. Operations were performed 55 to 76 days after injury, and operative findings were not different from those of common chronic subdural hematoma. From these investigations, it was suggested that there were two types of evolution of chronic subdural hematoma. One is the development from acute subdural hematomas, and the other from subdural hygromas. It is supposed that blood and cerebrospinal fluid are very important factors in the evolution of subdural collections into chronic subdural hematomas. (J.P.N.)

    Full Text Available Objectives: Organized triage has been useful method in immediate classification of large number of patients. Urgent intervention and evaluation of patients in Emergency Department result in shorter patient waiting time and, therefore, intensifying the quality of supervision. This study aimed at determining the causes of delays in patient triage in Emergency Departments (EDs in the city of Tabriz.Methods: This descriptive study was conducted in 18 hospitals of Tabriz, Iran. A questionnaire developed for this study was the only tool used in data collection. They were filled in by selected sample of ED staff, consisting 22 physicians and 135 nurses. The data was analyzed using the SPSS v.15.0 statistical software and descriptive analyses were used. Results: Findings of this study indicate that 75% of the survey was conducted in public and 25% in private hospitals. Based on the study results, major reasons of delay in patients priority processing include shortage of nursing staff (65%, large number of patients (50.3%, shortage of medical staff (38.2%, shortage of hospital resources (31.2%, shortage of medical equipment (26.8%, patients evaluation (13.4%, diagnostic tests (12.1%, advanced age of patients (5.7%, early age of patients (5.1%. Conclusions: Results of the study indicate that some of the major reasons of delay in priority processing of patients include shortage of nursing staff and large number of patients. Therefore, increasing staff number can be an efficient way to effectively manage the patient population in Emergency Department.

    BACKGROUND: Bannayan-Riley-Ruvalcaba syndrome (BRRS) is an autosomal dominant condition characterised by macrocephaly, developmental delay and subtle cutaneous features. BRRS results from mutations in the PTEN gene. In adults, PTEN mutations cause Cowden syndrome where, in addition to the macrocephaly, there is a higher risk of tumour development. Diagnosis of BRRS is often delayed as presentation can be variable, even within families. AIMS: To identify characteristics of this condition which might facilitate early diagnosis. Prompt diagnosis not only avoids unnecessary investigations in the child but potentially identifies heterozygote parents who are at risk of tumour development. METHODS AND RESULTS: Six children with a PTEN mutation were identified. All had extreme macrocephaly. Four parents and a male sibling were found to have a PTEN mutation on subsequent testing. Affected parents had extreme macrocephaly and a history of thyroid adenoma, or breast or skin lesions. All six children had presented to medical attention before the age of 2.5 years (3\\/6 were investigated as neonates), but the median age at diagnosis was 5 years. Four of the children had multiple investigations prior to identification of a PTEN mutation. CONCLUSION: BRRS should be considered in children with extreme macrocephaly as it is the most consistent clinical feature seen, particularly where there is a family history of macrocephaly.

    Full Text Available Renal subcapsular hematoma is not an uncommon complication after extracorporeal short wave lithotripsy, trauma, renal angiographic procedures and spontaneously in patients of malignancy and in patients on anticoagulation. We present a patient who developed renal subcapsular hematoma after ureterorenoscopy, which has not been mentioned in literature ever. Clinical spectrum varies from spontaneous resolution through acute renal failure to Page kidney. Page kidney is the external compression of a kidney usually caused by a subcapsular hematoma associated with high blood pressure and occasional renal failure. It is named after Dr. Irvin Page who first demonstrated in 1939 that wrapping cellophane tightly around animal kidneys could cause hypertension. Various management options are mentioned in literature and depend upon the severity of hematoma. Percutaneous drainage is a successful option for the management of subcapsular hematoma in hemodynamic stable patients.

    A spontaneous retropharyngeal hematoma is a rare condition with a difficult diagnostic. This disease may rapidly progress to an airway obstruction. The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed.

    Although bone infarction is a common feature in sickle cell disease, the involvement of the orbit is an unusual complication. Intracranial bleeding is another uncommon and serious complication. Few cases of orbital infarction alone have been reported. We report imaging findings (CT, bone scan, MRI) in a 16-year-old boy with sickle cell disease with orbital infarction and epidural hematoma. The precise cause of epidural hematoma is not well known, but it is probably related to vaso-occlusive episodes and the tearing of small vessels. (orig.)

    Full Text Available To determine the incidence and determinants of delayed graft function due to post-transplant acute tubular necrosis in live related donor renal transplantation. This is a retrospective study of 337 recipients of live related donor renal graft performed between1986 and 2006. Of these recipients, 24 (7.1% subjects developed delayed graft function with no evidence of acute rejection, cyclosporin toxicity, vascular catastrophe or obstructive cause and had evidence of acute tubular necrosis (ATN Group. These subjects were compared with recipients (n= 313, 92.9% who had no clinical or biochemical evidence of ATN. Mean age, and gender distribution of recipients was similar in the two groups (ATN group 35.7 ± 8.3, non-ATN group 34.3 ± 7.5, P= 0.43. Gender distribution of the recipients (men 279, 89.1% vs. 21, 87.5%, P= 0.80 as well as donors (women 221, 70.6% vs. 18, 75.0%, P= 0.75 was also similar. In ATN group as compared with non-ATN group the donor age was significantly greater (56.6 ± 8.3 vs. 46.6 ± 11.2 years, P< 0.0001. There was marginal difference in pre-operative systolic BP (154.5 ± 18.3 vs. 147.4 ± 20.2 mm Hg, P= 0.077 and significant difference in diastolic BP (87.8 ± 9.5 vs. 83.4 ± 11.4 mmHg, P= 0.041. Incidence of multiple renal arteries was similar (16.7% vs. 7.3%, P= 0.22. The warm ischemia time was significantly greater in ATN group (33.3 ± 6.2 min as compared to non-ATN group (30.4 ± 5.7 min, P= 0.042. Duration of hospital stay was more in ATN group (19.9 ± 6.7 vs. 16.8 ± 8.4 days, P= 0.04 but there was no difference in 1 year survival (284 subjects, 90.7% vs. 21 subjects, 87.5%, P= 0.873. This study shows that greater donor age, higher baseline diastolic BP and greater warm ischemia time are major determinants of delayed graft function due to acute tubular necrosis after related donor renal transplantation.

  6. Dynamic CT in the acute subdural hematoma

    International Nuclear Information System (INIS)

    Dynamic computed tomography (CT) was performed on thirteen patients with acute sudbural hematoma with and without diffuse cerebral swelling. The cause of the diffuse cerebral swelling accompanying the acute subdural hematoma is discussed in this paper. Patients were classified into two groups according to the Glasgow Coma Scale (GCS). Eight patients with a severe neurological state were judged to have GCS values of approximately 3-6 and to have diffuse cerebral swelling on the initial CT scan. All 8 patients had been rendered unconsciousness at the moment of injury and remained so until death. Five patients were judged to have moderate neurological states (GCS 9-13), and only two of these patients had mild cerebral swelling. The diagnosis of the diffuse cerebral swelling was made by means of the CT scan. The criteria are a marked increase in brain volume and a marked reduction in the size of the ventricular shadow and the basal cistern, or their absence. The dynamic CT of the brain consists of performing eight rapid serial scans after the bolus intravenous injection of 50 ml of a contrast material. The data from these scans were analyzed by means of the time-density curves of various brain regions. In 7 out of the 8 patients with diffuse cerebral swelling, the time-density curves of the cerebral hemisphere of the lesional side were always lower than those on the opposite side, and in 3 of these patients, the time-density curves of the lesional side were flat. However, in 1 patient with diffuse cerebral swelling and in 5 patients without diffuse cerebral swelling, the time-density curves of the cerebral hemisphere had obvious peaks and the curve of the lesional side was nearly identical with that of the opposite side. In 5 patients out of the 8 with severe acute subdural hematoma with diffuse cerebral swelling, the peak of the gray matter of the lesional side was not observed. (J.P.N.)

    1) Fourty cases of chronic subdural hematoma were operated on by trephination, irrigation and external drainage. Postoperative neurological recovery and decrease of hematoma cavity on CT scan were followed. 2) Operations were effective for recovery of neurological grade in 28 cases, moderately effective in 7 cases and not effective in 5 cases. 3) Within the tenth postoperative day, more than half residual hematoma cavity existed in 53% of examined cases. After that, more than half residual cavity existed in only 17%. 4) Preoperative feature of neurologically unimproved cases were no definite history of head trauma and water like low density of hematoma cavity. Postoperative feature was persistence of more than three fourth of residual hematoma cavity on CT scan. 5) A group of unimproved cases described above are thought to have a feature of subdural hygroma rather than subdural hematoma. When possibility of subdural hygroma is high in preoperative differential diagnosis, indication of operation should be different from chronic subdural hematoma.

  10. Antiangiogenesis therapy using a novel angiogenesis inhibitor, anginex, following radiation causes tumor growth delay

    International Nuclear Information System (INIS)

    The present study investigated whether treatment with anginex, a novel antiangiogenic peptide, could block re-vascularization after radiation treatment. A squamous cell (SCCVII) xenograft tumor mouse model was employed to assess the effects of anginex given post-radiation on tumor growth, microvessel density (MVD), and oxygen levels. The oxygen status was determined by the partial pressure of O2. Tumors in untreated mice increased threefold in 7.0 days, anginex-treated tumors (10 mg/kg intraperitoneal, twice) required 7.3±0.9 days, and tumors exposed to 8-Gy radiation increased threefold over 11 days. Combination treatment of anginex and radiation caused the tumors to grow threefold in 16.1±1.6 days, a delay which was significant and deemed supra-additive. Oxygen levels in tumors treated by stand-alone or combination therapies were significantly reduced; for example from 19.5±4.9 mmHg in controls to 9.7±1.9 mmHg in combination-treated, size-matched tumors. In addition, immunohistochemistry showed a decrease in MVD in the tumors treated with anginex, radiation, or the combination. These results suggest that a combination of anginex and radiation can greatly affect the amount of functional vasculature in tumors and prolong radiation-induced tumor regression. Antiangiogenesis therapy with anginex, in addition to radiotherapy, will be useful by blocking angiogenesis-dependent regrowth of vessels. (author)

  11. Blunt trauma as a suspected cause of delayed constrictive pericarditis: a case report

    Arabia Francisco A

    2011-02-01

    Full Text Available Abstract Introduction Constrictive pericarditis is a heterogeneous disease with many causes. Traumatic hemopericardium is an uncommon initiating cause. We report the case of a man developing constrictive pericarditis after blunt chest trauma, in order to highlight an approach to diagnosing the condition and to raise awareness of the possibility of this condition developing after blunt trauma. Case presentation A 72-year-old Caucasian man presented initially to our outpatient clinic with a one-year history of progressively worsening dyspnea, and recent onset of edema of the legs. He was later taken to the emergency department and admitted to hospital. He had previously received unsuccessful treatment from his local primary physicians for suspected respiratory disorder and cellulitis of his legs. Echocardiography showed evidence of pericardial constriction, and computed tomography revealed nodular, lobulated thickening of the pericardium and pleura bilaterally. Interventional biopsies were taken, but gave inconclusive results. Thus, as pericarditis and/or advanced malignancy were suspected, diagnostic video-assisted thoracoscopic surgery was performed to take biopsies from the abnormal lung and pericardial tissue. Examination of these supported the diagnosis of pericarditis, as acute and chronic inflammation and fibrous thickening were found, with no evidence of malignancy. Our patient underwent cardiac catheterization, which revealed three-vessel coronary artery disease. Emergency total pericardiectomy and coronary bypass were performed. Having excluded other common initiating factors, we considered that a blunt trauma that our patient had previously sustained to his chest was the potential cause of the constrictive pericarditis. Conclusion This was an interesting case of blunt chest trauma followed by progressive pericardial and pleural thickening. Subsequent development of chronic constrictive pericarditis occurred, requiring treatment by surgical pericardiectomy, as the clinical course of constrictive pericarditis is usually progressive without surgical intervention. Diagnosis of constrictive pericarditis remains challenging. Although uncommon, blunt trauma should be considered as a possible initiating cause. Delayed presentation of constrictive pericarditis should also be considered as a possible morbidity in a patient who has sustained blunt chest trauma. Our case also highlights the importance of performing echocardiography promptly in patients experiencing ongoing symptoms of congestive heart failure to allow earlier diagnosis of constrictive pericarditis or other cardiac disorders, and avoid unnecessary treatments.

    It is not uncommon to observe the dilatation of the pericerebellar fluid space (PCFS) on CT images in patients with subdural hematomas. CT scans of 67 patients with supratentorial subdural hematomas (SDH) proven by surgery were reviewed with respect to the dilatation of the PCFS. The dilatation of the PCFS was seen in 31 patients out of the 67 (46%). In 50 patients without SDH (control group), the dilatation of the PCFS was noted in only 6 (12%). Intrathecal metrizamide CT in 4 patients demonstrated that the PCFS was the cerebrospinal fluid (CSF) space. Twelve patients were followed with CT 1 to 12 months after the evacuation of the SDH. The dilatation of the PCFS had disappeared in 4, had slightly increased in volume in 2, and remained unchanged in 6. Although the mechanism of the dilatation of the PCFS in the patients with SDH is not clear, it can be postulated that the mechanism is caused by a CSF flow disturbance, compression, or adhesion of the subarachnoid space due to the SDH. We would like to emphasize that the recognition of PCFS dilatation is a clue to make a CT diagnosis of a SDH, particularly a bilateral isodense SDH.

  14. Is human fracture hematoma inherently angiogenic?

    LENUS (Irish Health Repository)

    Street, J

    2012-02-03

    This study attempts to explain the cellular events characterizing the changes seen in the medullary callus adjacent to the interfragmentary hematoma during the early stages of fracture healing. It also shows that human fracture hematoma contains the angiogenic cytokine vascular endothelial growth factor and has the inherent capability to induce angiogenesis and thus promote revascularization during bone repair. Patients undergoing emergency surgery for isolated bony injury were studied. Raised circulating levels of vascular endothelial growth factor were seen in all injured patients, whereas the fracture hematoma contained significantly higher levels of vascular endothelial growth factor than did plasma from these injured patients. However, incubation of endothelial cells in fracture hematoma supernatant significantly inhibited the in vitro angiogenic parameters of endothelial cell proliferation and microtubule formation. These phenomena are dependent on a local biochemical milieu that does not support cytokinesis. The hematoma potassium concentration is cytotoxic to endothelial cells and osteoblasts. Subcutaneous transplantation of the fracture hematoma into a murine wound model resulted in new blood vessel formation after hematoma resorption. This angiogenic effect is mediated by the significant concentrations of vascular endothelial growth factor found in the hematoma. This study identifies an angiogenic cytokine involved in human fracture healing and shows that fracture hematoma is inherently angiogenic. The differences between the in vitro and in vivo findings may explain the phenomenon of interfragmentary hematoma organization and resorption that precedes fracture revascularization.

    Subcapsular hematoma of the liver rarely occurs in neonates and the diagnosis is often missed or delayed. We report two babies who had this uncommon condition in the early neonatal period. In the first baby, the hematoma was associated with ventouse delivery and presented with abdominal distension and worsening jaundice. In contrast, the other baby was relatively well, with progressive pallor as the only clinical finding. The former had no other identifiable risk factors, whereas the latter was confirmed as having classical hemophilia. The literature is briefly reviewed with regards to incidence, etiology, diagnosis and management. Awareness of this unusual entity coupled with a high index of suspicion is essential for early identification and stabilization of such babies. PMID:22503263

    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.

    Subgaleal hematoma in the newborn infant is rare, occurs early, and often bears serious consequences. We report on 2 subacute cases of bruising of the scalp that occurred following the use of a suction cup. Emergency treatment consisted of a transfusion of packed red blood cells and fresh frozen plasma. Children born by use of vacuum extractor or forceps require careful monitoring by the nursing staff throughout their stay in the maternity unit. PMID:20851581

    Full Text Available Abstract Background Intraseptal hematoma and subsequent myocardial infarction due to accidental contrast agent deposition complicating diagnostic cineventriculography is a previously undescribed complication of angiography. Case presentation A 61 year old man was admitted at intensive care unit because of unstable angina pectoris 1 hour after coronary angiography. Transthoracic contrast echocardiography showed a non-perfused area in the middle of interventricular septum with an increase of thickening up to 26 mm. Review of cineventriculography revealed contrast enhancement in the interventricular septum after contrast medium injection and a dislocation of the pigtail catheter tip. Follow up by echocardiography and MRI showed, that intramural hematoma has resolved after 6 weeks. After 8 weeks successful stent implantation in LAD was performed and after 6 month the patient had a normal LV-function without ischemic signs or septal thickening demonstrated by stressechocardiography. Conclusion A safe and mobile position of the pigtail catheter during ventriculography in the middle of the LV cavity should be ensured to avoid this potentially life-threatening complication. For assessment and absolute measurement of intramural hematoma contrast-enhanced echocardiography is more feasible than MRI and makes interchangeable results.

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

The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1).

  10. MRI findings of traumatic spinal subdural hematoma

    To describe the MR imaging findings of traumatic spinal subdural hematoma. We retrospectively reviewed the MR images of six patients, with symptoms of acute spinal cord or cauda equena compression after trauma, together with spinal subdural hematoma. We analyzed the extent, location, configuration and signal intensity of the lesions. In five of sex cases, hematomas were distributed extensively throughout the thoracolumbosacral or lumbosacral spinal levels. In five cases they were located in the dorsal portion of the thecal sac, and in one case, in the ventral portion. On axial images, hematomas showed a concave or convex contour, depending on the amount of loculated hematoma. A lobulated appearance was due to limitation of free extension of the hematoma within the subdural space at the lateral sites (nerve root exist zone) at whole spine levels, and at the posteromedian site under lumbar 4-5 levels. In cases of spinal subdural hematoma, the lobulated appearance of hematoma loculation in the subdural space that bounds the lateral sites at al spinal levels and at the posteromedian site under L4-5 levels is a characteristic finding.

Acute lung injury (ALI recurred 31 days after the first ALI episode. Both ALI episodes occurred 48 hours after transfusion. Laboratory examinations revealed the presence of various antileukocyte antibodies including antiplatelet antibody in the recipient's serum but not in the donors' serum. The authors speculate that antiplatelet antibodies can have an inhibitory effect in the recipient, which can modulate the bona fide procedure of ALI and lead to a delay in the onset of ALI.

    Full Text Available Paget?s disease of skull usually causes neurological complications such as basilar invagination, cranial neuropathies, etc. Occurrence of extradural hematoma in association with Paget?s disease of skull is rare. A 48 year old man presented with headache and right upper limb weakness, two days after a fall from scooter. CT Scan of brain showed a large extradural hematoma at the vertex with the cranial vault showing features of Paget?s disease. At surgery, no skull fracture or injury to the superior sagittal sinus was evident. There was diffuse oozing from the inner table of the skull, which showed features of Paget?s disease. The extradural hematoma was evacuated and the patient made good recovery.He deteriorated a few hours after surgery. Follow up CT Scan showed diffuse brain swelling with minimal recollection of hematoma. Re-exploration showed a small recollection which was evacuated and the part of the oozing diseased skull was excised. The patient recovered completely. This is the first reported case of vertex extradural hematoma in association with the Paget?s disease of skull. The unusual features are the absence of skull fracture and injury to the superior sagittal sinus. The increased vascularity of the skull due to Paget?s disease has caused the hematoma by diffuse oozing from the inner table.

    BACKGROUND Trauma is the leading cause of death in people younger than 45 years and head injury is the main cause of trauma mortality. Although epidural hematomas are relatively uncommon (less than 1% of all patients with head injuries and fewer than 10% of those who are comatose), they should always be considered in evaluation of a serious head injury. Patients with epidural hematomas who meet surgical criteria and receive prompt surgical intervention can have an excellent prognosis, presumably owing to limited underlying primary brain damage from the traumatic event. The decision to perform a surgery in a patient with a traumatic extraaxial hematoma is dependent on several factors (neurological status, size of hematoma, age of patients, CT findings) but also may depend on the judgement of the treating neurosurgeon. CASE REPORT A 30-year old man arrived at our Emergency Department after a traumatic brain injury. General examination revealed severe headache, no motor or sensory disturbances, and no clinical signs of intracranial hypertension. A CT scan documented a significant left fronto-parietal epidural hematoma, which was considered suitable for surgical evacuation. The patient refused surgery. Following CT scan revealed a minimal increase in the size of the hematoma and of midline shift. The neurologic examination maintained stable and the patient continued to refuse the surgical treatment. Next follow up CT scans demonstrated a progressive resorption of hematoma. CONCLUSIONS We report an unusual case of a remarkable epidural hematoma managed conservatively with a favorable clinical outcome. This case report is intended to rather add to the growing knowledge regarding the best management for this serious and acute pathology. PMID:26567227

    Outcome in cancer may be improved by early diagnosis and prompt treatment. The objectives of this study were to determine the prediagnostic intervals (lag time) in childhood cancer and the factors that influence them at the University College Hospital (UCH), Ibadan. The study was prospective and observational and involved children diagnosed with cancer from July 2012 to June 2014 at UCH, Ibadan, Nigeria. A history of the illness was obtained and physical examination performed on each patient. Information obtained and analyzed included sociodemographic data, cancer diagnosis and stage, time intervals between onset of symptoms and diagnosis, and the reasons for delayed diagnosis. A total of 91 children were studied, comprising 46 males and 45 females. Their ages ranged from 1 month to 15.0 years, with a median of 4.0 years. Median parent lag time was 2.0 weeks, median health system or physician lag time 8.0 weeks, and median overall lag time 15.5 weeks. Overall lag time had a negative correlation with age of child at diagnosis, a positive correlation with the number of health facilities visited before diagnosis, and was shorter in mothers younger than 40 years of age. Lag time was significantly different among the diagnostic tumor categories, with Burkitt lymphoma having short times and retinoblastoma with long times. Delayed diagnosis of childhood cancer is a significant problem in Ibadan. Education of parents and health workers on early presentation and accurate diagnosis are recommended. PMID:26086955

    Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

    In clinical forensic medicine, the estimation of the age of injuries such as externally visible subcutaneous hematomas is important for the reconstruction of violent events, particularly to include or exclude potential suspects. Since the estimation of the time of origin based on external inspection is unreliable, the aim of this study was to use contrast in MRI to develop an easy-to-use model for hematoma age estimation. In a longitudinal study, artificially created subcutaneous hematomas were repetitively imaged using MRI over a period of two weeks. The hemorrhages were created by injecting autologous blood into the subcutaneous tissue of the thigh in 20 healthy volunteers. For MRI, standard commercially available sequences, namely proton-density-weighted, T2 -weighted and inversion recovery sequences, were used. The hematomas' MRI data were analyzed regarding their contrast behavior using the most suitable sequences to derive a model allowing an objective estimation of the age of soft tissue hematomas. The Michelson contrast between hematoma and muscle in the proton-density-weighted sequence showed an exponentially decreasing behavior with a dynamic range of 0.6 and a maximum standard deviation of 0.1. The contrast of the inversion recovery sequences showed increasing characteristics and was hypointense for TI = 200ms and hyperintense for TI =1000ms. These sequences were used to create a contrast model. The cross-validation of the model finally yielded limits of agreement for hematoma age determination (corresponding to ±1.96 SD) of ±38.7h during the first three days and ±54 h for the entire investigation period. The developed model provides lookup tables which allow for the estimation of a hematoma's age given a single contrast measurement applicable by a radiologist or a forensic physician. This is a first step towards an accurate and objective dating method for subcutaneous hematomas, which will be particularly useful in child abuse. PMID:25208978

    Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leucosis (EBL), to which animals are most susceptible at 4-8 years of age. In this study, we examined tumor cells associated with EBL in an 18-year-old cow to reveal that the cells carried at least two different copies of the virus, one of which was predicted to encode a reverse transcriptase (RT) lacking ribonuclease H activity and no integrase. Such a deficient enzyme may exhibit a dominant negative effect on the wild-type RT and cause insufficient viral replication, resulting in delayed tumor development in this cow. PMID:26025155

    tert-butyl hydroperoxide (tBHP), an organic peroxide, has been shown to cause irreversible damage to keratinocytes in vitro with prolonged administration at high concentrations, and reversible damage with short-term administration at low concentrations. To investigate the effects of tBHP on keratinocytes in vivo, we analysed hair growth in tBHP-treated neonatal rats. Sprague-Dawley and Long-Evans rat pups were injected subcutaneously with tBHP or vehicle once daily for 6?days, and hair growth was monitored. The tBHP-treated rats had a significant delay in hair growth. However, this delay reversed within days, and the hair coats, including hair pigmentation, of tBHP-treated and sham-treated rats were indistinguishable 2?weeks later. Histological analysis and BrdU labelling of S phase cells confirmed the delay in hair-follicle growth and its reversal in tBHP-treated rats. Our results indicated that the changes incurred in hair follicles by short-term use of high-dose oxidants in vivo are temporary and reversible. PMID:21418283

Continuous variables were presented as mean ± standard deviation and the differences were compared with the Student's t test. Values of p d" 0.05 were considered significant. Results: In group A the mean BP (110-70mmHg ± 7.07) and HR (64 / min ± 5) were lower (p d" 0.05) than in group B (135-90mmHg ± 10.6) and (76 / min ± 7.5), respectively. There were four cases of expansive hematoma in group B, all requiring reoperation for drainage, and none in group A (p d" 0,001). Conclusion: The perioperative use of atenolol caused a decrease in blood pressure and heart rate and decreased the incidence of expanding hematoma after rhytidectomy.

    The instantaneous state of a neural network consists of both the degree of excitation of each neuron, the network is composed of, and positions of impulses in communication lines between neurons. In neurophysiological experiments, the neuronal firing moments are registered, but not the state of communication lines. But future spiking moments depend essentially on the past positions of impulses in the lines. This suggests, that the sequence of intervals between firing moments (interspike intervals, ISIs) in the network could be non-Markovian. In this paper, we address this question for a simplest possible neural "net", namely, a single neuron with delayed feedback. The neuron receives excitatory input both from the driving Poisson stream and from its own output through the feedback line. We obtain analytical expressions for conditional probability density $P(t_{n+1} | t_n,...,t_1,t_0)$, which gives the probability to get an output ISI of duration $t_{n+1}$ provided the previous $(n+1)$ output ISIs had duration...

  5. Delayed-onset bilateral abducens paresis after head trauma

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

  6. A Case of Spontaneous Spinal Epidural Hematoma Mimicking Stroke

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking.

  7. Spontaneous disappearance of acute subdural hematoma on CT scan

    International Nuclear Information System (INIS)

    We encountered a patient with a severe head injury complicated by DIC in whom the serial CT scans revealed the disappearance of the subdural hematoma. A 65-year-old man received a heavy blow to the head in a traffic accident. On admission, the patient was in a coma (Glasgow's coma scale: 5 points), showing anisocoria (right > left) and left hemiplegia. He later deteriorated in ataxic respiration and died 23 hours after the trauma. In a blood-coagulation examination done 2 hours after the trauma, the bleeding time was 9 minutes, the coagulation time was more than 60 minutes, the serum fibrinogen was less than 15 mg/dl, and the serum FDP was above 160 ug/ml; a diagnosis of DIC was thus made. CT scans 1 hour after the trauma showed acute subdural hematoma in the right cerebral hemisphere, a medial displacement of the lateral ventricles, and a traumatic subarachnoid hemorrhage. In CT scans taken 21 hours after the trauma, however, the subdural hematoma had disappeared, while a diffuse swelling of the cerebrum, mottled high-density areas along the cerebral sulci, and high-density areas in the posterior horns of the bilateral ventricles as well as in the cerebello-pontine angle were observed for the first time. These changes in the CT findings are considered to be due to the decrease in the viscosity of the subdural hematoma caused by the markedly enhanced activity of the fibrolytic system with DIC and by subsequent diffusion into intracranial spaces under the increased intracranial pressure associated with the development of cerebral edema.

  8. Study on the causes of cost increases and delays in the construction of the SNR-300 reactor

    International Nuclear Information System (INIS)

    The summary gives a survey of the essential investigation results both of the 'Study on the causes of cost increases and delays in the construction of the SNR-300 reactor' carried through from August 1981 to May 1982 and of the 'Pursuance and evaluation of the new total cost assessment' carried through between May and August 1982. The target consisted in a comprehensive analysis in order to establish and judge the causes of past cost increases and delays in construction time. This would provide a basis for critically reviewing the implementation prospects of the existing project schedule and to evolve effective and lasting measures for improving the further realization of the project. Moreover conclusions of general validity were to be drawn from the experience gathered with the SNR-300 project and comparable international projects with a view to increasing the efficiency of publicly promoted large-scale research projects in the nuclear sector. The study covers the total duration of the SNR-300 project, the most important organizations and institutions participating in the project and the essential functions relative to the project.

    Deficiency of Asparagine Synthetase (ASNSD, MIM 615574) is a very rare autosomal recessive disorder presenting with some brain abnormalities. Affected individuals have congenital microcephaly and progressive encephalopathy associated with severe intellectual disability and intractable seizures. The loss of function of the asparagine synthetase (ASNS, EC 6.3.5.4), particularly in the brain, is the major cause of this particular congenital microcephaly. In this study, we clinically evaluated an affected child from a consanguineous Emirati family presenting with congenital microcephaly and epileptic encephalopathy. In addition, whole-exome sequencing revealed a novel homozygous substitution mutation (c.1193A?>?C) in the ASNS gene. This mutation resulted in the substitution of highly conserved tyrosine residue by cysteine (p.Y398C). Molecular modeling analysis predicts hypomorphic and damaging effects of this mutation on the protein structure and altering its enzymatic activity. Therefore, we conclude that the loss of ASNS function is most likely the cause of this condition in the studied family. This report brings the number of reported families with this very rare disorder to five and the number of pathogenic mutations in the ASNS gene to four. This finding extends the ASNS pathogenic mutations spectrum and highlights the utility of whole-exome sequencing in elucidation the causes of rare recessive disorders that are heterogeneous and/or overlap with other conditions.

    Dengue fever, also known as breakbone fever, is an infectious tropical disease caused by the Dengue virus. It is associated with a number of complications, which are well documented. However, Dengue fever associated with rectus sheath hematoma (RSH) is a very rare complication. Only one case report has been published prior supporting the association of Dengue fever with RSH. We report a case of Dengue fever who presented with RSH and was successfully treated conservatively. RSH is also an uncommon cause of acute abdominal pain. It is accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. PMID:25161976

    In dairy cattle, udder edema (18 to 96%) and retention of fetal membranes (3,6 to 29%) are very common disorders around calving. Previous studies suggests that udder edema (UE), retained fetal membranes (RFM), and mastitis have a common cause. We studied whether a link between the prevalence of them might to be found. We found no correlation between UE and RFM. Despite the suggested relation where this research was based on, evidence for such a relation was not found. Scoring udder edema is n...

    We report the case of a 10-year-old boy with a full thickness chemical burn on his right pretibial area due to phytophotodermatitis (PPD) following contact with giant hogweed (Heracleum mantegazzianum). Although cutaneous burns due to plants are a well-established cause of chemical burn, previous reports described partial thickness burns that healed with conservative measures. This patient presented to our unit two weeks after the initial injury with an established full thickness burn. Debridement and split thickness skin grafting was required. We presented the histological features of the debrided skin specimen and discussed potential factors leading to this unexpected full thickness injury.

    A 19-year-old male construction worker presented with an injury to his left upper arm after lifting a heavy pipe. He reported an acute onset of sharp pain followed by swelling, warmth, and weakness with elbow flexion. The diagnosis of a distal biceps tendon rupture was made and elective repair was scheduled. Seventy-two hours later, the patient presented with a spontaneous draining wound on his anterior distal humerus. The wound was draining thick purulent material. The patient underwent surgery for irrigation and debridement of his abscess. Nearly 500 cc of hematoma and purulent fluid were evacuated. A large tear of both the biceps and brachialis muscle bellies were found. Cultures were obtained that revealed the infecting organism to be Streptococcus intermedius. Human immunodeficiency virus and hepatitis-C virus testing were negative, and no history, signs, or symptoms of any cause of underlying immunodeficiency were detected. No signs or history of drug use were present. He was discharged home on culture-specific oral antibiotics. At 4-month postoperative follow-up, the patient reported no pain or limitations. He has returned to full duty at his job. Elbow range of motion was measured from 7° to 150° of flexion. Strength of elbow flexion and extension was symmetric to the uninjured side. Pronation and supination of the forearm was symmetric on both sides. He has been released from scheduled follow-up and will be seen again on an as-needed basis. PMID:21053873

The answer is yes. → This study shows that developmental speed of frog embryo was dose-dependently decreased by rapamycin treatment. → In additions, morphogenetic effects such as less pigmentations and gut malformation are occurred by rapamycin. -- Abstract: Rapamycin is a drug working as an inhibitor of the TOR (target of rapamycin) signaling pathway and influences various life phenomena such as cell growth, proliferation, and life span extension in eukaryote. However, the extent to which rapamycin controls early developmental events of amphibians remains to be understood. Here we report an examination of rapamycin effects during Xenopus early development, followed by a confirmation of suppression of TOR downstream kinase S6K by rapamycin treatment. First, we found that developmental speed was declined in dose-dependent manner of rapamycin. Second, black pigment spots located at dorsal and lateral skin in tadpoles were reduced by rapamycin treatment. Moreover, in tadpole stages severe gastrointestinal malformations were observed in rapamycin-treated embryos. Taken together with these results, we conclude that treatment of the drug rapamycin causes enormous influences on early developmental period.

  19. Clinical study of treatment of cerebral hemorrhage: remove the intracranial hematoma with a minimal invasive procedure

    International Nuclear Information System (INIS)

    Objective: To study the feasibility and factors of minimal invasive intracranial hematoma removing procedure as a treatment of cerebral hemorrhage. Methods: From May, 2000 to September, 2003, 33 patients with intracerebral hemorrhage underwent minimal invasive intracranial hematoma removing procedure and from May, 1997 to September, 2000, 27 patients with cerebral hemorrhage received conservative treatments. Two groups were compared and analyzed. The quantity of hemorrhage and the indication of procedure were also studied. Results: State of an illness has no significant difference between the two groups (P<0.05). The rate of recovery were higher in the group undergoing the procedure (57.6%) than in the control group (14.8%) (P<0.05). The rate of handicap were lower in the procedure group (24.0%) than in the control group (60.0%) (P<0.05). The mortality were also lower in the procedure group (24.2%) than in the control group (63.0%) (P<0.01). In the control group no patient with a hematoma larger than 70 ml survived. In the procedure group patients with hematoma larger than 70 ml had less chance of survival than the other patients (P<0.01). The mortality rate were respectively 50%, 5.6%, 33.3% when the procedure was done in super early, early, delayed stage. The mortality rate was higher in the super early stage than in early stage (P<0.05). Conclusion: The minimal invasive intracranial hematoma removing procedure has a better clinical outcome than the conservative treatment. The procedure reduces obviously mortality rate and increase the quality of survival. Multiple puncturing and draining or craniotomy are recommended to remove huge hematoma. The earlier treatment brings better clinical effects. This technique is simple, less invasive and provides good clinical outcome, which is worth recommendation

    Objective. Subdural hygroma is reported to occur in 5%-20% of all patients with closed head trauma, the treatment is controversial and in symptomatic cases surgical drainage is need. We report on a new case with remote acute epidural hematoma (AEH) after subdural hygroma drainage. Case Presentation. A 38-year-old man suffered blunt head trauma and had diffuse axonal injury grade III in CT scan. A CT scan that was late performed showed an increasing subdural fluid collection with mild mass effect and some effacement of the left lateral ventricle. We perform a trepanation with drainage of a hypertensive subdural collection with citrine aspect. Postoperative tomography demonstrated a large left AEH. Craniotomy and evacuation of the hematoma were performed. Conclusion. The mechanism of remote postoperative AEH formation is unclear. Complete reliance on neurologic monitoring, trust in an early CT scan, and a relative complacency after an apparently successful initial surgery for hygroma drainage may delay the diagnosis of this postoperative AEH.

    Purpose: Spinal epidural hematoma (SEH) is a rare clinical entity with a bleak outcome. The aim of our study was to establish the value of MR findings in the diagnosis of nontraumatic SEH. Material and Methods: Seven patients with nontraumatic SEH were examined by MR at 1.5 T. Two patients were under anticoagulation therapy with heparin, and 2 others were taking salicylic acid. One patient had lupus erythematodes with a marked thrombocytopenia. One patient had a spinal arteriovenous malformation. Results: MR imaging permitted the accurate localization of extradural intraspinal expansive lesions which exhibited the characteristic signal intensities of blood. Five patients underwent laminectomy and evacuation of the hematoma. In the acute phase, the hematomas appeared isointense when compared with the spinal cord on T1-weighted images and hyperintense on T2-weighted images. Later the hematomas were hyperintense on T1-weighted images and showed signals identical to those of cerebrospinal fluid (CSF) on T2-weighted images. Conclusion: MR imaging established the exact diagnosis and localization of SEH in all cases. MR also can provide useful information about the age of the hematomas. (orig.).

    A postoperative epidural hematoma (EDH) is a serious and embarrassing complication, which usually occurs at the site of operation after intracranial surgery. However, remote EDH is relatively rare. We report three cases of remote EDH after brain tumor surgery. All three cases seemed to have different causes of remote postoperative EDH; however, all patients were managed promptly and showed excellent outcomes. Although the exact mechanism of remote postoperative EDH is unknown, surgeons should be cautious of the speed of lowering intracranial pressure and implement basic procedures to prevent this hazardous complication of brain tumor surgery.

  6. Computer tomography of intracranial tumours and hematomas

    International Nuclear Information System (INIS)

    The value of computed tomography (CT) for the diagnosis of intracranial tumors and hematomas was investigated in a retrospective study comprising 220 patients. All C.T.scans are reviewed and described in detail. To assess the diagnostic accuracy, the original interpretation of the C.T.scans was compared with that of conventional neuroradiological and neurophysiological examinations. The aspect on C.T. of the various types of tumors and hematomas proved to vary widely and specific features were seldom seen. This holds particularly for the malignant tumors. Benign tumors such as meningeomas, adenomas and neurilemmomas showed a rather easily identifiable and almost identical picture of the C.T.scan, and diagnosis had to be based mainly on differences in localization. The hematomas, with the exception of the older intracerebral ones, showed the most characteristic C.T.abnormalities. (Auth.)

    A 72-year-old female presented with a unique case of acoustic neurinoma with a cystic component followed by the chronic subdural hematoma manifesting as trigeminal neuralgia, facial palsy and trunchal ataxia 7 months after gamma knife radiosurgery. Magnetic resonance imaging demonstrated a loss of central contrast enhancement at the postoperative residual tumor mass and a large cyst associated with a hematoma in the subdural space. A right suboccipital craniectomy was performed. A biopsy of the mass and the membrane was performed following aspiration of the brown-reddish fluid collection. The histological diagnosis was acoustic neurinoma with a hemorrhagic necrosis. The membranous tissue mimicked an outer membrane obtained from chronic subdural hematoma. The postoperative course was satisfactory and preoperative symptom have been alleviated. In this case, the chronic subdural hematoma occurred at posterior fossa during the development of cysts caused by the radiosurgery, because the subdural space had been connected with the subarachnoid space after the first operation. The development of cysts or hematoma should be taken into consideration as possible complications following treatment with gamma knife radiosurgery for acoustic neurinomas. (author)

    Full Text Available Abstract Abdominal wall hematoma is a rare and life-threatening complication after carotid artery stenting (CAS, but it can occur when activated clotting time is prolonged. We report a right lateral abdominal wall hematoma caused by rupture of the superficial circumflex iliac artery after CAS in a 72-year-old man with severe stenosis of the origin of the right internal carotid artery. We performed CAS for the targeted lesion while activated clotting time exceeded 300 seconds. After 2 hours, he complained of right lateral abdominal pain. Abdominal computed tomography revealed an extensive hematoma in the right lateral abdominal wall. Activated clotting time was 180 seconds at this point. Seven hours later, he developed hypotension and hemoglobin level dropped to 11.3 g/dl. Subsequent computed tomography showed enlargement of the hematoma. Emergent selective angiography of the external iliac artery revealed active bleeding from the right superficial circumflex iliac artery. Transcatheter arterial embolization with Gelfoam and microcoils was performed successfully. With more CAS procedures being performed, it is important for endovascular surgeons and radiologists to consider the possibility of abdominal wall hematoma in this situation.

    Full Text Available Abstract Background The occurrence of pulmonary artery obstruction in the course of acute aortic dissection is an unusual complication. The mechanism implicated is the rupture of the outer layer of the aorta and the subsequent hemorrhage into the adventitia of the pulmonary artery that causes its wall thickening and, at times, produces extrinsic obstruction of the vessel. There are no reports of this complication in acute intramural hematoma. Case presentation An 87-year-old woman was admitted to the hospital in shock after having had severe chest pain followed by syncope. An urgent transesophageal echocardiogram revealed the presence of acute intramural hematoma, no evidence of aortic dissection, severe pericardial effusion with cardiac tamponade, and periaortic hematoma that involved the pulmonary artery generating circumferential wall thickening of its trunk and right branch with no evidence of flow obstruction. Urgent surgery was performed but the patient died in the operating room. The post mortem examination, in the operating room, confirmed that there was an extensive hematoma around the aorta and beneath the adventitial layer of the pulmonary artery, with no evidence of flow obstruction. Conclusion This is the first time that this rare complication is reported in the scenario of acute intramural hematoma and with the transesophageal echocardiogram as the diagnostic tool.

    Hematoma of the cervical ligamentum flavum is very rare, and its pathogenesis is unknown. We describe a case of ligamentum flavum hematoma in the cervical spine causing severe myelopathy. Postoperative histological examination suggested it was the result of the rupture of a hemangioma or of an arteriovenous malformation in the ligamentum flavum. After removal of the lesion, the patient's condition immediately improved. Review of all three reported cases, including this one, showed that complete resection of the mass resulted in immediate relief of symptoms of incomplete paraplegia. The findings of magnetic resonance imaging (MRI) of the hematoma may vary with time, and they may show no characteristic intensity. However, MRI of this case revealed that the tissues surrounding the mass were enhanced with gadolinium diethylene triamine penta-acetic acid, and an area of homogeneous iso-intensity was clearly surrounded by a low-intensity area (flavum) on T2-weighed short-tau inversion recovery images. These findings could be characteristic of the ligamentum flavum hematoma and might help in the differentiation from a cervical epidural hematoma. (orig.)

    Full Text Available Subdural hematoma is a rare but serious complication following electroconvulsive therapy (ECT, a frequently used treatment modality in the management of various psychiatric morbidities including bipolar affective disorder (BAD. There are very few reports of intracranial bleeding following ECT in the literature. A 38-year-old female, known case of BAD for last fifteen years receiving ECT, presented with the symptoms of dysphasia, headache, left sided paresis, and sudden deterioration of sensorium. Computed tomography (CT scan of the brain was suggestive of left-sided fronto parietal chronic subdural hematoma with midline shift that was drained successfully.

    A 17-year-old, previously healthy, male breakdancer presented with a three-month history of crescendo headache and newly identified papilledema. The patient was found to have four separate, unilateral extracranial collections. At surgery, three were subdural hematomas, and one was a probable arachnoid cyst containing a hematoma. These were removed, and the patient made an uneventful recovery with no neurosurgical sequelae. The possibility of serious head injury must be considered when evaluating headache in youngsters who engage in this new and apparently popular dance form. PMID:3800063

    Full Text Available A 77-year-old man suffered hypoxemic cardiac arrest by supraglottic and tracheal airway obstruction in the emergency department. A previously unknown cervical fracture had caused a traumatic retropharyngeal-mediastinal hematoma. A lifesaving surgical emergency tracheostomy succeeded. Supraglottic and tracheal obstruction by a retropharyngeal-mediastinal hematoma with successful resuscitation via emergency tracheostomy after hypoxemic cardiac arrest has never been reported in a context of trauma. This clinically demanding case outlines the need for multidisciplinary airway management systems with continuous training and well-implemented guidelines. Only multidisciplinary staff preparedness and readily available equipments for the unanticipated difficult airway solved the catastrophic clinical situation.

    Full Text Available Placement of lumboperitoneal (LP shunt as a surgical treatment for benign intracranial hypertension (BIH is generally a safe procedure, with complications like mechanical failure, overdrainage and infections. Subarachnoid hemorrhage and intracerebral hematoma were seen after lumboperitoneal shunt in a patient having BIH. These complications were the cause of the patient?s deterioration. After removal of the hematoma and performing a decompressive procedure, patient?s neurological condition improved. The clinical features, investigations and clinical course are described and the literature reviewed.

    An 80-year-old man was admitted for acute subdural hematoma caused by a mild brain injury. His coagulation test showed an isolated prolongation of activated partial thromboplastin time (aPTT). Though the subdural hematoma did not progress, oozing bleed from the wound of tracheostomy continued. Failure of correction on aPTT mixing test supported the presence of an inhibitor to a coagulation factor. Once the diagnosis of acquired hemophilia A (AHA) was made, steroid therapy was performed, which leads him to complete remission of AHA. Isolated prolongation of aPTT can be the key to diagnose a rare coagulopathy, such as AHA. PMID:26491582

    Chronic expanding hematoma is a rare presentation of a hematoma characterized by a persistent increase in size for more than a month after the initial hemorrhage. We present a 65-year-old man with a chronic expanding hematoma in his ilium who was receiving anticoagulant treatment. The patient had a delayed manifestation of a femoral neuropathy with massive bone destruction. 2-Deoxy-[{sup 18}F]fluoro-d-glucose (FDG) positron emission tomography (PET) imaging revealed an increased uptake in the rim of the mass in images acquired 1 h after FDG injection. FDG-PET scans were performed using a dedicated PET scanner (HeadtomeV/SET2400 W, Shimadzu, Kyoto, Japan), and the PET data for the most metabolically active region of interest (ROI) were analyzed. The maximum standardized uptake value (SUVmax) was set to a cut-off point of 3.0 to distinguish between benign and malignant lesions. The SUVmax of the patient's lesion was 3.10, suggesting a malignant lesion. The characteristics of FDG-PET images of chronic expanding hematomas, including the uptake of FDG in the peripheral rim of the mass as a result of inflammation, should be recognized as a potential interpretive pitfall in mimicking a sarcoma.

    Tennis leg, strain of the medial head of the gastrocnemius muscle, may follow a trivial trauma in athletic and nonathletic activities. Complete or partial tears of the musculotendinous unit may result in a hematoma. Clinical manifestations of gastrocnemius hematoma in a 64-year-old man with local swelling, pain and tenderness that was aggravated by passive dorsiflexion of the ankle joint, mimicked deep vein thrombosis. Failure to appreciate the precedent trivial trauma and the localized swelling and ecchymosis led to delayed diagnosis and inappropriate heparinization. The definite diagnosis was established by CT scan which revealed a local soft tissue mass within the gastrocnemius consistent with a hematoma. A compartment syndrome developed the day after heparinization and was adequately treated by discontinuation of heparin, aspiration and rest. Differentiation between tennis leg and deep vein thrombosis is of paramount importance, since the etiology, treatment and prognosis of these two clinical entities are quite different. Venography is recommended as specifically diagnostic for deep vein thrombosis while CT scan for gastrocnemius hematoma. PMID:2794964

    Burr-hole craniostomy with closed-system drainage is a safe and effective method for the management of chronic subdural hematoma. However, contralateral acute subdural hematoma has been reported to be a rare and devastating complication. Only 3 cases have been described in the literature. Herein, we reported an 80-year-old male with chronic subdural hematoma and contralateral subdural hygroma. The burr-hole craniostomy with closed-system drainage was initially performed to treat the chronic subdural hematoma. Three days after surgery, weakness of the extremities developed, and contralateral acute subdural bleeding within the previous subdural hygroma was diagnosed by CT scan of the brain. The pathophysiological mechanism of this rare complication was discussed, and the relevant literature was also reviewed. PMID:24983286

    Life-threatening large subcutaneous hematomas after minor injury are rare clinical states for young people; however these patients may have hidden diseases, which can cause a tendency to bleed. A 31-year-old woman visited our hospital after minor injury. The first computed tomography (CT) scan revealed a small subcutaneous hematoma, but her head bulged and the second CT scan revealed her subcutaneous hematoma had become enlarged. Two surgeries were needed to stop the bleeding and. Though she received intensive care, she died 48 days after onset. The new Ehlers-Danlos syndrome (EDS), known as EDS Kosho type (EDSKT), is a connective tissue disease, in which patients often experience large subcutaneous hematomas. We suspected our patient had EDSKT because her clinical features were compatible with this syndrome. Our findings support the notion that large subcutaneous hematomas in young patients with connective tissue disease can be fatal; a careful follow-up is required. PMID:25972953

    Full Text Available Introducción: La introducción de la fragmentación por ondas de choque en el campo de la litiasis urinaria es una de las mayores aportaciones terapéuticas en la historia de la urología. Es el método de elección para el tratamiento de la mayoría de los cálculos de ubicación renal y ureteral, ya que es [...] un método poco invasivo y con bajo número de complicaciones; pero su aplicación no está totalmente exenta de efectos adversos. Produce traumatismo o lesión más o menos importante en los órganos que atraviesan las ondas de choque, incluido el riñón, donde pueden producir desde una pequeña contusión a hematomas renales con diferente resolución y tratamiento. Material y métodos: Realizamos una revisión de 4.815 litotricias que se han realizado en nuestro servicio, exponiendo siete casos en los que se diagnosticó hematomas renales subcapsulares o perirrenales, con su evolución, manejo y tratamiento. Resultados: Después de las complicaciones urológicas (dolor, obstrucción e infección), las colecciones hemáticas renales y perirrenales ocupan el primer lugar en orden de frecuencia en cuanto a efectos adversos de las ondas de choque, relacionándose fundamentalmente con la potencia de energía aplicada y con el incremento de edad del paciente. Conclusiones: Entre los años 1992-2007 se realizaron 4.815 litotricias con un total de 7 casos de hematomas graves, que representan menos del 1%. El manejo suele ser conservador si bien en ocasiones es necesario el drenaje quirúrgico o incluso la nefrectomía. Abstract in english Introduction: The use of fragmentation due to shock- waves as a treatment of urinary stone was one of the most important therapeutics findings in the history of urology. It´s the first election treatment for most of the calculus at renal and urethral location due to the fact that it is a low invasiv [...] e treatment and it has a few number of complications, but this method also has a few negative side effects, it can caused a more or less important traumatic lesion at the organs which crosses the shock- waves, including the kidney where it can caused a small contusion or renal hematoma with different resolution and treatment. Material and method: We reviewed 4815 extracorporeal shock-wave lithotripsy that we performed in our department in which we found six cases with subcapsular and perirrenal hematoma which we followed up and treated. Results: After the urological complications (pain, obstruction and infection) the renal and perirrenal hematic collections are the most frequent adverse effects of shock- waves used in lithotripsy, these are related to the power of energy used and patient age. Conclusions: Between the years 1992-2007 we performed 4.815 extracorporeal shock-wave lithotripsy finding seven cases of severe hematoma, less then 1%.Treatment of these complications is usually not aggressive though sometimes it is necessary to perform surgical drainage and even nephrectomy.

  6. Inactivation of the nucleus reuniens/rhomboid causes a delay-dependent impairment of spatial working memory.

    Inactivation of the rodent medial prefrontal cortex (mPFC) and hippocampus or disconnection of the hippocampus from the mPFC produces deficits in spatial working memory tasks. Previous studies have shown that delay length determines the extent to which mPFC and hippocampus functionally interact, with both structures being necessary for tasks with longer delays and either structure being sufficient for tasks with shorter delays. In addition, inactivation of the nucleus reuniens (Re)/rhomboid nucleus (Rh) of the thalamus, which has bidirectional connections with the mPFC and hippocampus, also produces deficits in these tasks. However, it is unknown how delay duration relates to the function of Re/Rh. If Re/Rh are critical in modulating mPFC-hippocampus interactions, inactivation of the RE/Rh should produce a delay-dependent impairment in spatial working memory performance. To investigate this question, groups of rats were trained on one of three different spatial working memory tasks: continuous alternation (CA), delayed alternation with a five-second delay (DA5), or with a thirty-second delay (DA30). The Re/Rh were inactivated with muscimol infusions prior to testing. The results demonstrate that inactivation of RE/Rh produces a deficit only on the two DA tasks, supporting the notion that the Re/Rh is a critical orchestrator of mPFC-HC interactions. PMID:26391450

    Study Design Case report and literature review. Objective Spinal subdural hematomas are rare events that often progress with severe neurologic deficits. Although there have been several case reports in the literature of spontaneous spinal subdural hematomas in the setting of anticoagulation, antiplatelet therapy, or coagulation disorders, the exact pathophysiology of such phenomena remains obscure. Methods We present the first report of a subdural hematoma after a percutaneous vertebroplasty and provide a comprehensive review on the anatomy of venous drainage of the vertebral bodies with emphasis on the possible effects of venous congestion caused by cement obstruction. Results Because the subdural hematoma occurred in the absence of major cement extravasation to the spinal canal and two levels above the site of the vertebroplasty, we discuss the possible role of venous congestion as the main etiologic factor leading to rupture of the fragile, valveless radiculomedullary veins into the subdural space. Conclusions The reported case supports a possible new pathophysiological scheme for the development of spinal subdural hematoma in which venous congestion plays a pivotal etiologic role. The reported findings suggests that future anatomical and histologic studies investigating the response of the radiculomedullary veins to congestive venous hypertension may shed new light into the pathophysiology of spinal subdural hematomas.

    Full Text Available CONTEXT: Although endoscopic esophageal variceal sclerotherapy has been largely supplanted by variceal band ligation, it is still performed routinely in many institutions, especially in developing countries. Intramural esophageal hematoma has been described as a rare complication of sclerotherapy. Risk factors have not been completely established. OBJECTIVE: To demonstrate the incidence of post-sclerotherapy intramural esophageal hematoma in our hospital and discuss the possible factors involved. Methods - This is a retrospective observational study made at the "Hospital Universitário Clementino Fraga Filho", Rio de Janeiro, RJ, Brazil, reviewing the medical records of all esophageal variceal sclerotherapy procedures performed from April 2000 to November 2005. The evaluation of the clinical, laboratorial and endoscopic features in our patients and those reported in the literature was also done. Review of literature was performed through MEDLINE search. RESULTS: A total of 1,433 esophageal variceal sclerotherapy procedures were performed in 397 patients, with an intramural esophageal hematoma incidence of 4 cases (0.28%. Three of our patients developed additional complications, and one death was a direct consequence of a rupture of the hematoma. Nineteen well described cases were reported in the literature. Intramural esophageal hematoma occurred mostly after the forth esophageal variceal sclerotherapy session. Coagulation disturbances were present in the majority of cases. CONCLUSION: Intramural esophageal hematoma is a rare complication of esophageal variceal sclerotherapy and its incidence in our institution was similar to those observed in the literature. Our study suggests that this complication occurs as a result of a fragile esophageal mucosa after previous esophageal variceal sclerotherapy sessions. Impaired coagulation, although not essential, could contribute to hematoma formation and extension through esophageal submucosa.CONTEXTO: Apesar do fato de que a escleroterapia endoscópica de varizes esofágicas vem sendo largamente substituída pela técnica de ligadura elástica, a escleroterapia é ainda rotineiramente utilizada em muitas instituições, especialmente em países em desenvolvimento.

    Rectus sheath hematoma (RSH) develops due to rupture of epigastric arteries or the rectus muscle. Although RSH incidence rate is low, it poses a significant diagnostic dilemma. We evaluated the risk factors for RSH, its presentation, management, and outcomes for 115 patients hospitalized with confirmed RSH by computed tomography scan between January 2005 and June 2009. More than three-fourth (77.4%) of the patients were on anticoagulation therapy, 58.3% patients had chronic kidney disease (CKD) stage ?3, 51.3% had abdominal injections, 41.7% were on steroids/immunosuppressant therapy, 37.4% had abdominal surgery/trauma, 33.9% had cough, femoral puncture was performed in 31.3% of patients, and 29.5% were on antiplatelet therapy. Rectus sheath hematoma was not an attributable cause in any of the 17 deaths. Mortality was significantly higher in patients with CKD stage ?3 (P = .03) or who required transfusion (P = .007). Better understanding of RSH risk factors will facilitate early diagnoses and improve management. PMID:25294636

    Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists. PMID:24553773

  12. Benefits of Artcereb on the irrigation of chronic subdural hematoma

    International Nuclear Information System (INIS)

    Chronic subdural hematoma is thought to be an easily treatable disease. However, its recurrence rate is approximately 10%, and such cases require re-operation. We compared the recurrance rate of chronic subdural hematoma with irrigation using either saline or the artificial cerebrospinal fluid Artcereb. We divided the patients into 2 groups. A total of 60 patients in the normal saline group (hematoma, n=58; bilateral hematoma, n=2) underwent irrigation with saline between March 2007 and July 2009. A total of 61 patients in the Artcereb group (hematoma, n=54; bilateral hematoma, n=7) underwent irrigation using Artcereb between August 2009 and May 2011. We performed irrigation via 1 burr hole with 500-1000 ml of either normal saline or Artcereb under local anesthesia and observed until recurrence or disappearance of the hematomas on CT scan. We researched the recurrence rate of the hematomas. Recurrence of the hematomas were observed in 8 cases (13%) in the normal saline group and 5 cases (8.2%) in the Artcereb group. No statistically significant differences were observed. Among those patients who did not receive anticoagulants, the recurrence rate was 6/54 (11%) in the normal saline group and 1/49 (2.0%) in the Artcereb group (p<0.10). Our study showed the possibility that the postoperative recurrence rate of chronic subdural hematoma was lower using Artcereb than saline for irrigation. (author)

  13. Unusual brachial plexus lesion: Hematoma masquerading as a peripheral nerve sheath tumor

    Directory of Open Access Journals (Sweden)

    Khaled M Krisht

    2016-01-01

    Full Text Available Background: Malignant peripheral nerve sheath tumors (MPNSTs of the brachial plexus have unique radiographic and clinical findings. Patients often present with progressive upper extremity paresthesias, weakness, and pain. On magnetic resonance (MR imaging, lesions are isointense on T1-weighted and hyperintense on T2-weighted sequences, while also demonstrating marked enhancement on MR studies with gadolinium diethylenetriamine pentaacetic acid. On the basis of their characteristic MR imaging features and rapid clinical progression, two brachial plexus lesions proved to be organizing hematomas rather than MPNST. Methods: A 51-year-old male and a 31-year-old female were both assessed for persistent and worsened left-sided upper extremity pain, paresthesias, and weakness. In both cases, the MR imaging of the brachial plexus demonstrated an extraspinal enhancing lesion located within the left C7-T1 neuroforamina. Results: Although the clinical and radiographic MR features for these 2 patients were consistent with MPNSTs, both lesions proved to be benign organizing hematomas. Conclusions: These two case studies emphasize that brachial plexus hematomas may mimic MPNSTs on MR studies. Accurate diagnosis of these lesions is critical for determining the appropriate management options and treatment plans. Delaying the treatment of a highly aggressive nerve sheath tumor can have devastating consequences, whereas many hematomas resolve without surgery. Therefore, if the patient has stable findings on neurological examination and a history of trauma, surgical intervention may be delayed in favor of repeat MR imaging in 2-3 months to re-evaluate the size of the mass.

    Symptomatic intraneural hemorrhage occurs rarely. It presents with pain and/or weakness in the distribution following the anatomic innervation pattern of the involved nerve. When a purely sensory nerve is affected, the symptoms can be subtle. We present a previously healthy 36-year-old female who developed an atraumatic, spontaneous intraneural hematoma of her sural nerve. Sural dysfunction was elicited from the patient's history and physical examination. The diagnosis was confirmed with magnetic resonance imaging, and surgical decompression provided successful resolution of her preoperative symptoms. To our knowledge, this entity has not been reported previously. Our case highlights the importance of having a high index of suspicion for nerve injury or compression in patients whose complaints follow a typical peripheral nerve distribution. Prior studies have shown that the formation of intraneural hematoma and associated compression of nerve fibers result in axonal degeneration, and surgical decompression decreases axonal degeneration and aids functional recovery.

  16. Initial hematoma pressure and clinical recurrence of chronic subdural hematoma in cases where percutaneous subdural tapping was performed

    International Nuclear Information System (INIS)

    Percutaneous subdural tapping for chronic subdural hematoma (CSDH) can measure initial hematoma pressure, which cannot be measured using burr-hole craniotomy. Initial hematoma pressure has not been discussed as a risk factor for recurrence. We evaluated the clinical features for recurrence, which included initial hematoma pressure. The study involved 71 unilateral CSDH cases whose initial hematoma pressure was measured using percutaneous subdural tapping. Clinical recurrence was identified in 19 cases (23%). Age, sex, neurological grading, alcohol consumption, presence of head injury, hypertension, diabetes mellitus, antiplatelet, anticoagulant medication, hematoma volume on computed tomography (CT) images, and initial hematoma pressure were compared between non-recurrence and recurrence groups. The initial hematoma pressure was 12.6±4.5 cmH2O in the non-recurrence group, and 15.5±6.2 cmH2O in the recurrence group (p<0.05). The other factors did not differ significantly except hematoma volume on CT images (92±45 ml in the non-recurrence group and 123±43 ml in the recurrence group, p<0.05). Cases with high initial hematoma pressure should be closely observed. (author)

    Spontaneous liver bleeding is often reported in preeclampsia. It is otherwise rare and has been linked to gross anatomical lesions and coagulopathy. We report a case of subcapsular hematoma of the liver without any apparent lesion and in the absence of coagulopathy. A 41-year-old male, paraplegic for 16 years, presented to the emergency department 3 days after sudden onset of right upper quadrant and shoulder pain. He had been on vitamins and 5,000 units subcutaneous heparin 12-hourly at the nursing home for the last month. He was in no distress, afebrile, with stable vitals. Physical examination showed a diverting colostomy, tender hepatomegaly and sacral decubiti. A fecal occult blood test was negative. There was spastic paraplegia below the level of T12. Two days after admission, the patient was afebrile and hemodynamically stable. PTT, PT, liver profile, BUN and creatinine were all normal, however his hemoglobin had dropped from 11.3 to 7.6 g/dl. An abdominal CT scan revealed an isolated 9.0 × 1.8 cm subcapsular hematoma. The patient received blood transfusion in the intensive care unit and was discharged 7 days later. In conclusion, spontaneous liver hemorrhage occurs in the nonobstetrical population in the setting of gross anatomical lesions or coagulopathy. This is the first report of an isolated subcapsular liver hematoma. PMID:21552450

    CT examinations were performed in 621 cases of minor head injury within 3 days, and 26 cases (4%) exhibited hygroma-like CT findings. These 26 cases were divided into two patterns: Type A (12 cases) and Type B (14 cases). Type A showed smooth thin hygroma-like low density area beneath the skull with compression of the cerebral surface and cerebral sulci. Type B showed an irregular thin hygroma-like low density area beneath the skull with recognized cerebral sulci. Many of these cases changed into chronic subdural hematomas, i.e. Twelve cases (100%) of Type A and three cases (21%) of Type B changed into chronic subdural hematomas. It is highly possible to forecast the subsequent occurrence of the chronic subdural hematomas soon after a head injury.

    Full Text Available Acute spontaneous subdural hematoma in a patient of multiple myeloma receiving chemotherapy is an unknown event, needing an urgent neurosurgical management. We report this patient who presented with progressive neurological deterioration and a low platelet count.

    We report on a patient with an unusual, slowly enlarging hematoma of the left buttock. A 62-year-old man presented with a 6-year history of an enlarging mass of the left buttock. He had first noted the mass 6 years earlier and had had sciatica of the left lower limb for the last 2 months. He denied any history of antecedent trauma. The lesion extended over 3 gluteal muscles (the gluteus medius, gluteus minimus, and piriformis). On microscopic examination, the lesion showed typical signs of chronic expanding hematoma. The sciatica was relieved after surgical removal of the lesion. The lesion had not recurred at the last follow-up 4 years after the operation. The present case suggested that chronic expanding hematoma can extend into multiple muscles due, perhaps, to long-term growth and the anatomical and functional conditions of the affected muscles. Our case also suggests that chronic expanding hematoma can be a cause of piriformis syndrome. PMID:23291848

Los procedimientos anestésicos raquídeos y epidurales representan la décima causa más frecuente. Pero en combinación con el tratamiento anticoagulante, dichos procedimientos aumentan su incidencia hasta alcanzar la quinta causa. Publicamos un caso clínico de hematoma epidural cervical yatrogénico en el adulto y el buen resultado obtenido con tratamiento conservador. Caso clínico: Paciente varón de 80 años, que a las 2 horas de tratamiento analgésico de cervicoartrosis mediante infiltración epidural cervical desarrolla intensa cervicalgia y pérdida de fuerza en extremidades inferiores, mostrando paraplejia completa con arreflexia. En RM cervical se evidencia hematoma epidural entre los niveles C4 y T1. Es trasladado a nuestro centro para cirugía pero ante la rápida recuperación se decide tratamiento médico conservador. Al mes de seguimiento, la situación clínica es similar a la previa, sin secuelas con completa reabsorción del hematoma en RM control. Conclusión: Actualmente, la tendencia general es realizar cirugía en pacientes con hematoma espinal y empeoramiento neurológico importante durante las primeras horas. Sin embargo, se pueden obtener buenos resultados neurológicos con tratamiento conservador, en pacientes bien seleccionados con déficit parcial, incompleto y no progresivo. En el presente, no estamos en condiciones de decir qué tratamiento es el mejor para cada caso concreto. Abstract in english Background: Around 600 spinal epidural hematoma cases have been previously reported. Incidence of paraplegia after epidural anesthesia varies between 0,0005 and 0,02%. Several possible etiologies have been described in the literature, including surgery, trauma, anticoagulant therapy, arteriovenous m [...] alformations, pregnancy and lumbar puncture. Spinal and epidural anesthesic procedures represent the tenth most common cause. But in combination with anticoagulant therapy, the forementioned procedures increase its incidence until reaching the fifth most common etiological group. We report the case of an 80 year-old-man with a cervical epidural hematoma who had a good outcome with conservative management. Case report: 80 year-old-man that developed intense cervicalgia with lower limbs weakness showing complete paraplegia and arreflexia 2 hours after analgesic treatment with epidural cervical infiltration for cervicoartrosis. Cervical MRI showed epidural cervical hematoma between C4 and T1 levels. The patient is transferred to our facilities in order to perform surgery. But after showing fast recovery, medical conservative management was elected. After one month, the patient's condition has improved showing no neurological deficits and complete resorption is seen in MRI. Conclusions: Nowadays, trend is to perform surgery in patients with spinal hematoma and significant neurological deterioration during the first hours. However, good neurological outcomes can be achieved with conservative management, in well selected patients with non progressive, incomplete and partial deficits. Presently, we can not predict wich is the best treatment for each case.

    Full Text Available Abstract Background It is well known in the literature that imaging has almost no value for diagnosis of superficial bladder cancer. However, wide gap exists between knowledge on diagnosis of bladder cancer and actual clinical practice. Case presentation Delay in diagnosis of bladder cancer in a male person with tetraplegia occurred because of reliance on negative flexible cystoscopy and single biopsy, negative ultrasound examination of urinary bladder, and computerised tomography of pelvis. Difficulties in scheduling cystoscopy also contributed to a delay of nearly ten months between the onset of haematuria and establishing a histological diagnosis of vesical malignancy in this patient. The time interval between transurethral resection and cystectomy was 42 days. This delay was mainly due to scheduling of surgery. Conclusion We learn from this case that doctors should be aware of the limitations of negative flexible cystoscopy and single biopsy, cytology of urine, ultrasound examination of urinary bladder, and computed tomography of pelvis for diagnosis of bladder cancer in spinal cord injury patients. Random bladder biopsies must be considered under general anaesthesia when there is high suspicion of bladder cancer. Spinal cord injury patients with lesions above T-6 may develop autonomic dysreflexia; therefore, one should be extremely well prepared to prevent or manage autonomic dysreflexia when performing cystoscopy and bladder biopsy. Spinal cord injury patients, who pass blood in urine, should be accorded top priority in scheduling of investigations and surgical procedures.

    Extradural hematoma (EDH) occurs in approximately 2% of all patients with head injuries. Bilateral EDHs account for 2–10% of all acute EDHs in adults but are exceedingly rare in children. Posterior fossa EDHs occurs in 5% of all cases of EDHs. EDHs in children are more frequently venous (from tears of a dural sinus or diploic veins) and consequently have a better prognosis than EDHs in adults. Once the diagnosis of BEH is confirmed, urgent surgical treatment should be considered. We are reporting such rare form of injury as bilateral occipital EDH with supratentorial extension in 12 years child following road traffic accident.

    2015-03-01

    Full Text Available Subdural hematoma in supratentorial location occur due to rupture of bridging veins or by laceration of falx, the latter entity being extremely uncommon cause of hemorrhage in full term new-born neonate who has been delivered by non-instrumental vaginal delivery. Compressive effects on the fetal parietal bones by rigid maternal pelvic structures result in frontal–occipital elongation and vertical or oblique molding. This in turn causes cranio-caudal stretching of both the falx and tentorium. Normally the give-away is at the falcine and tentorial junctions, rarely only falcine laceration can result. Most of massive subdural hematomas due to falx laceration, tentorial laceration or occipital diastasis have a rapid lethal course or patients may have permanent neurological disability. We describe a case of full term neonate who had extensive subdural and parenchymal hemorrhage resulting from falcine tear.

    Extracranial hematoma without significant head trauma is uncommon. We discuss a 9-year-old girl who presented with sudden head swelling, bilateral proptosis, extraocular muscle palsy, and progressive visual disturbance after hair braiding. The diagnosis of a large subgaleal hematoma with extension into the superior aspect of the orbits was made, requiring surgical drainage. Hematologic workup revealed an underlying Factor XIII deficiency. (orig.)

  1. Treatment of acute traumatic epidural hematoma in infancy and childhood

    International Nuclear Information System (INIS)

    The authors treated 22 cases of epidural hematoma diagnosed by CT scan. This study focused on the analysis of the time-course and development of epidural hematoma using a CT scan. The results are follows: 1. Severe cases must be treated by craniotomy and rapid removal of hematoma. We achieved a zero mortality rate in the cases of infants and children. 2. Normal CT findings were not unusual in cases where the patient was examined within 3 hours after the occurence of the injury. Conservative treatment was indicated for patients with a small amount of epidural hematoma. CT scanning at intervals of 6 hours and 30 hours after the occurence of the injury offer the best correlation in regard to the course of hematoma. 3. Operative treatment is required when the hematoma thickness, measured by CT scan, is more than 20 mm for infants and younger children or 30 mm for school aged children. However, eventhough the thickness of the hematoma maybe less than these guidelines, when progressive deterioration occurs after the CT scan, operative treatment must be considered. 4. Diffuse brain injury is a new clinical entity found by CT scanning. We classified this into 5 types. Of the 5 types, ''diffuse cerebral swelling'' was observed in the initial CT scan of two patients, however, epidural hematoma developed afterwards. Thus, patients with diffuse cerebral swelling with a skull fracture must be closely observed. (J.P.N.)

    Full Text Available Context: Retroperitoneal hematoma may usually occur as a result of trauma. A life threatening retroperitoneal hematoma is not expected complication of anticoagulation treatment and rarely reported. Low molecular weight heparins (Enoxaparin which are used as effective and safe medicine in the venous thromboemboly treatment have some major complications such as hematomas of different organs. We aim to present a giant spontaneous retroperitoneal hematoma after anticoagulant treatment of pulmonary embolism with enoxaparin. Case Report: A 73-year-old male patient with the diagnosis of pulmonary embolism underwent anticoagulant treatment (enoxaparin. In the second day of admission, the patient had an episode of abdominal and back pain. Abdominal ultrasonography and computerized tomographic scan revealed a giant retroperitoneal hematoma. Enoxaparin treatment was then stopped and the supportive treatment was started. In the following days, hemoglobin levels returned to normal and a control CT revealed regression of hematoma size. Conclusion: The anticoagulant treatment with enoxaparin may lead to severe hematomas. Therefore, the clinical suspicion is required especially in elderly patients and patients with impaired renal function for retroperitoneal hematoma, when they suffer from acute abdominal pain.

  3. Delayed Puberty

    Full Text Available Puberty is a quite important phase in the physical and psychosocical development of the adolescent. The timing of puberty is variable and is dependent on several factors including ethnic group, nutrition and genetic factors. It may commence from 8 years of age in girls and 9 years in boys and is usually complete after 3,5 years in female and 2,5 years in males. Delayed puberty is defined as the lack of secondary sexual characteristics from the age of 13 years in females and 14 years in males. The most common cause is constitutional delay in growth and puberty. It is more common in boys and most cases are familial, usually occurring in the same-sex parent. This typically occurs in healthy children who have delayed puberty with short stature for their chronological age, but this delay is appropriate for the bone age. Pubertal delay can be classified according to circulating levels of luteinizing hormone and follicle stimulating hormone. Central nervous system abnormalities result in hypogonadotrophic hypogonadism and gonadal failure causes hypergonadotrophic hypogonadism. A detailed history is the first step in the diagnostic evaluation of a constitutional delay and abnormal puberty. Further evaluation includes laboratory testing (estradiol, testosterone, the results of a GnRH test, karyotip analysis and imaging studies (X-ray of the left hand and wrist, USG of the gonads, MRI . Treatment is directed at both the acute and long-term consequences of delayed or absent pubertal development. Delayed puberty and other pubertal disorders should be recognized early, correctly diagnosed by a pediatric endocrinologist, and appropriately treated. (Turk Arch Ped 2011; 46 Suppl: 88-91

    Full Text Available A 75-year-old Taiwanese man suffered from acute onset of right-sided extremity weakness while talking to his neighbors. He was transferred to the hospital within three-hour time after symptom onset. Initial acute ischemic cerebral infarct was diagnosed based on his symptom and cerebral computed tomography. Thrombolytic therapy was held after his symptom improved promptly and could not excluded other etiology. Thorough history taking unraveled previous Chinese medicine clinic visit because of neck sore. However, he received limited improvement after several times of massage treatment. Magnetic resnance imaging (MRI of the cervical spine demonstrated hematoma compressing right side intradural-extramedullary space at the C2/C3 level. Through his clinical course, muscle weakness was the sole neurological finding with sparing of sensory defects. Given the close anatomy relationship between sensory and motor lamina distribution in the cervical spinal cord, our patient presented a rare manifestation. Cases of cervical spine intradural-extramedullary hematoma are not often seen and only sporadic in the documented literature. We wish, through the report of this article, to inform the first- line physicians with the following information. Among the elderly, neck sore is a common symptom. Over- stretching or overt local massage is not suggested due to relatively fragile musculature. In the clinical diagnosis and localization of lesion, cerebral or cervical spine lesion could mimic with each other and manifest hemiparesis as their first symptom. Meticulous history taking, neurological/ physical examination and pertinent laboratory work-up should be done before initiation of intravenous thrombolytic therapy as it could cause catastrophic consequences if not used properly.

    Intrahepatic sarcomatoid cholangiocarcinomais is a very rare disease with a poor prognosis due to its biologically aggressive tumor behavior. We report a patient who presented with subcapsular hemorrhage and a rapidly growing liver mass. A 57 year-old man was admitted with severe abdominal pain. CT and MRI images showed the presence of a 10 cm-sized subcapsular hemorrhage connected with a multi-lobulated mass with hemorrhage and necrotic foci in the right liver. The patients underwent right hemihepatectomy with caudate lobectomy and lymphadenectomy. The operation findings revealed metastatic nodules to the diaphragm and omentum. Detailed histopathological analysis through immunohistochemistry confirmed the diagnosis of sarcomatoid cholangiocarcinoma with a poorly undifferentiated sarcomatous component. The patient underwent chemotherapy. To date, the patient is doing well for 8 months after initial diagnosis. PMID:26388910

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

    Yamaoka, Hiroshi; Karasawa, Kaori

    2006-04-01

    Two studies were conducted to examine the effect of affects on self-control behavior in delayed cost dilemma. Results of Study 1 suggested that long term negative affects such as regret and self-disgust might have facilitating effects on motivation of self-control if they were anticipated before delayed-cost dilemma situations, but inhibiting effects on self-efficacy of control when experienced after dilemma situations. Study 2 examined the effect of affect priming on self-control in eating behavior, as well as an interaction effect of anticipated affect and regulatory resource on it. Results indicated that participants who had enough regulatory resource succeeded in self-control, i.e. they ate less, regardless of the type of affect priming, but those who did not have sufficient resource and were not primed with long-term negative affects failed to control their behavior. It was argued that regulatory resource explanation of self-control should be expanded to the theory including anticipated affects. PMID:16862961

    Recent studies revealed the power of whole-exome sequencing to identify mutations in sporadic cases with non-syndromic intellectual disability. We now identified de novo missense variants in NAA10 in two unrelated individuals, a boy and a girl, with severe global developmental delay but without any major dysmorphism by trio whole-exome sequencing. Both de novo variants were predicted to be deleterious, and we excluded other variants in this gene. This X-linked gene encodes N-alpha-acetyltransferase 10, the catalytic subunit of the NatA complex involved in multiple cellular processes. A single hypomorphic missense variant p.(Ser37Pro) was previously associated with Ogden syndrome in eight affected males from two different families. This rare disorder is characterized by a highly recognizable phenotype, global developmental delay and results in death during infancy. In an attempt to explain the discrepant phenotype, we used in vitro N-terminal acetylation assays which suggested that the severity of the phenotype correlates with the remaining catalytic activity. The variant in the Ogden syndrome patients exhibited a lower activity than the one seen in the boy with intellectual disability, while the variant in the girl was the most severe exhibiting only residual activity in the acetylation assays used. We propose that N-terminal acetyltransferase deficiency is clinically heterogeneous with the overall catalytic activity determining the phenotypic severity. PMID:25099252

    Radiotherapy is used to treat advanced stages of cervical cancer. Despite optimization of the doses delivered during radiotherapy chronic urinary tract complications still occur in 1-5% of patients. We report a case of 60 years old woman, treated 10 years ago for stage III cervical carcinoma. She received both intracavitary brachytherapy and external teletherapy. Since irradiation patient suffered from the stress urinary incontinence (SUI). She was diagnosed in our department and underwent successful anti-incontinence surgery. Because of oncological history and urodynamic parameters (markedly lowered closing urethral pressure) she was assigned to intravaginal slingplasty transobturator (IVS-OT) procedure with delayed positioning of the tape. There were no intra- or postoperative complication. The check-up done four months following surgery revealed that patient have full control of micturition and markedly improved quality of life.

  18. Nonaneurysmal subarachnoid hemorrhage in intramural hematoma of the basilar artery - a case report and literature review

    International Nuclear Information System (INIS)

    Pretruncal (perimesencephalic) nonaneurysmal subarachnoid hemorrhage (SAH) is a benign variant of SAH. Although angiography fails to show a source of the hemorrhage, mild basilar artery narrowing may be observed. The cause of pretruncal nonaneurysmal SAH has not been established. Recent imaging studies have demonstrated that the center of this type of SAH is not around the mesencephalon but is in the prepontine or interpeduncular cistern with the hemorrhage closely associated with the basilar artery. We review the possible sources of hemorrhage in these cisterns and hypothesize that pretruncal nonaneurysmal SAH is caused by a primary intramural hematoma of the basilar artery. Such an intramural hematoma would explain bleeding under low pressure, the location of the hemorrhage anterior to the brainstem, and the typical findings of hemorrhage adjacent to the basilar artery lumen on magnetic resonance imaging and mild basilar artery narrowing on angiography. Hemorrhage in such location is easily found in native computed tomography (CT) images. Crescent, hyperdense thickening of the basilar artery wall is also observed. We have presented this unusual case to highlight the possible mechanism of hematoma formation and underline the importance of MDCT examination in the diagnosis confirmation and also excluding other potentially serious underlying condition that could also lead to non traumatic SAH.

    Chromatin remodeling through histone acetyltransferase (HAT) and histone deactylase (HDAC) enzymes affects fundamental cellular processes including the cell-cycle, cell differentiation, metabolism, and apoptosis. Nonsense mutations in genes that are involved in histone acetylation and deacetylation result in multiple congenital anomalies with most individuals displaying significant developmental delay, microcephaly and dysmorphism. Here, we report a syndrome caused by de novo heterozygous nonsense mutations in KAT6A (a.k.a., MOZ, MYST3) identified by clinical exome sequencing (CES) in four independent families. The same de novo nonsense mutation (c.3385C>T [p.Arg1129?]) was observed in three individuals, and the fourth individual had a nearby de novo nonsense mutation (c.3070C>T [p.Arg1024?]). Neither of these variants was present in 1,815 in-house exomes or in public databases. Common features among all four probands include primary microcephaly, global developmental delay including profound speech delay, and craniofacial dysmorphism, as well as more varied features such as feeding difficulties, cardiac defects, and ocular anomalies. We further demonstrate that KAT6A mutations result in dysregulation of H3K9 and H3K18 acetylation and altered P53 signaling. Through histone and non-histone acetylation, KAT6A affects multiple cellular processes and illustrates the complex role of acetylation in regulating development and disease. PMID:25728775

    A 65-year-old woman visited our hospital with a complaint of acute onset dyspnea and radiological manifestations of pulmonary thromboembolism. The patient underwent an exploratory surgery to find a whitish-blue colored mass occupying almost the whole lumen of the main pulmonary arteries. Based on the pathological and radiological findings, the patient was diagnosed to have a pulmonary arterial intramural hematoma. Intramural hematomas are usually observed in the walls of the aorta, and we believe that an isolated intramural hematoma in the pulmonary artery has not been described previously.

  2. Dabigatran-related Intracerebral Hemorrhage Resulting in Hematoma Expansion

    DEFF Research Database (Denmark)

    Simonsen, Claus Z; Steiner, Thorsten

    2014-01-01

    Warfarin-related intracerebral hemorrhage carries a particularly high risk of neurologic deterioration and death because of a high rate of hematoma expansion of about 50%. Novel oral anticoagulants (NOACs)-apixaban, dabigatran, and rivaroxaban-have a significantly smaller risk of intracerebral hemorrhage (ICH). However, two facts make this situation complicated: First, the risk of hematoma expansion is unknown for NOACs. Second, there is no specific antidote for neither of the NOACs. We present a case that suggests that hematoma expansion may occur after NOAC-related ICH.

  3. Changes in signal intensity of cerebral hematoma in magnetic resonance

    International Nuclear Information System (INIS)

    Magnetic resonance is highly sensitive for the detection of intraparenchymatous hemorrhage. The evolution of hematoma over time translates into changes in signal intensity. This means that we can determine when the hematoma presented and, in addition. follow its course. On the other hand, many intracranial processes developing association with hemorrhage, the recognition of which is, in some cases, of importance. We have studied 60 cerebral hematomas and have described the changes that will take place in their signal and the reasons for them. (author)

    We report a case of type A intramural aortic hematoma (IMH) occurred in a 78 years old female. The clinical scenario (medical history of hypertension, severe substernal chest pain, early diastolic decrescendo murmur as for aortic insufficiency), the laboratory results (no significant troponin level), ECG and transthoracic echocardiography findings (no signs of myocardial ischemia) shifted the initial diagnostic suspicion from acute coronary syndrome to the acute aortic syndrome (AAS) and triggered further imaging tests. Computed tomography revealed an aneurismatic dilatation with thickening of the wall of the ascending aorta without intimal flap. No particular "warning message" for evidence of AAS was sent to the clinician on call. Subsequently, due to the persisting high clinical suspicion transesophageal echocardiography (TEE) was performed. TEE confirmed the aneurysm of the ascending aorta and highlighted an extended and marked aortic wall thickness, consisting with the diagnosis of type A IMH. Patient underwent urgent cardiac surgery that confirmed the diagnosis. PMID:21751738

  5. Computed tomographic investigations on intraventricular hematomas

    International Nuclear Information System (INIS)

    This work investigated in 106 patients with intraventricular hematomas all the known factors which can have an influence on prognosis: age, sex, anamnesis of the patients, size, extent and localization of the intracranial bleeding, underlying angiopathy and differences between arterial and venous and spontaneous and traumatic bleedings. It was shown that the state of mind was the deciding prognostic factor, whereby viligance was the cumulative expression of all other investigated influences. A computed tomography (CT) examination is deciding in the question of operative hydrocephalus care. In 13 patients it was further shown, how clearly CT results and brain dissection allowed themselves to be compared. The computed tomographic examination method is best suited to achieve even physiological and more extensive prognostic possibilities. (orig.)

Group A, 18 patients, had a poor outcome. Fifteen patients out of 18 had the removal of hematoma and decompression craniectomy with 10 deaths, 4 vegetative states and 1 severe disability. Three patients died without surgery. Group B, 17 patients, were treated surgically in the same way as in group A and all patients had a good recovery with 14 making a full recovery and 3 with a moderate disability. Surgical mortality was 31.3% and overall mortality was 37.1%. The features of the CT findings in 18 patients of group A were as follows. Eleven patients had midline shift of more than 15 mm, 9 had subdural high density area of more than 15 mm and 12 patients had bilateral collapse of the lateral ventricles. The charactaristic finding of CT recognized in all patients of group A was disappearance of the ambient cistern. On the contrary, in 17 patients of group B the displacement of the intracranial structure was not so severe as in group A. The midline shift of 14 patients was less than 7.5 mm, the width of subdural high density area of 15 patients was less than 7.5 mm and the ambient cistern was recognized in 12 patients. For 11 patients out of 15 in group A, the operation was performed within 6 hours following the onset of head trauma, however, 9 patients died, one in a vegetative state and one had severe disability postoperatively. Thirteen patients out of 17 in group B were operated on later than 6 hours after the onset of the head trauma, and yet took a good outcome. (J.P.N.)

    Magnetic resonance is highly sensitive for the detection of intraparenchymatous hemorrhage. The evolution of hematoma over time translates into changes in signal intensity. This means that we can determine when the hematoma presented and, in addition. follow its course. On the other hand, many intracranial processes developing association with hemorrhage, the recognition of which is, in some cases, of importance. We have studied 60 cerebral hematomas and have described the changes that will take place in their signal and the reasons for them. (author)

    2010-12-01

    Full Text Available Traumatic epidural hematoma (EDH represents a rare head injury complication in the newborn. EDH is seen in 2-3 % of all head injuries in the pediatric population. A case of epidural hematoma by an accidental trauma due to the dropping of the patient to the labor room floor was reported. The male newborn's birth weight was 2650 gr. His neurologic examination revealed left hemiparesis. A solid epidural hematoma was recognized on Computed Tomography (CT. The hematoma was decompressed surgically. He was discharged from the hospital at the 3th day. The treatment of the newborn EDH is controversial. Treatment may be conservative, surgical or interventional needle aspiration. Etiology and treatment of the newborn EDH are discussed.

  9. Idiopathic intraparenchymal hematoma of the liver in a neonate

    International Nuclear Information System (INIS)

    Hepatic hematomas in newborn infants are not frequently detected clinically, but are often found at perinatal autopsies. These hematomas of the liver are usually subcapsular in location. A variety of etiologies for such hematomas has been implicated, such as trauma, sepsis, and coagulopathies. We present a neonate who presented with jaundice and abdominal distention. Initial imaging studies revealed a large intraparenchymal lesion of the liver, which was at first thought to be suspicious for neoplasm; however, MRI showed the lesion to be hemorrhagic and follow-up sonographic studies showed total resolution of this lesion, compatible with hematoma. The intraparenchymal location and the idiopathic nature of this lesion distinguish this case from others previously reported. (orig.)

  13. Analysis of chronic subdural hematoma based on CT, (2)

    International Nuclear Information System (INIS)

    Twenty-three cases of chronic subdural hematoma were observed soon after head injury for the relationship between its CT findings and clinical symptoms. It has been found that the chronic subdural hematoma is a slowly growing and expanding intracranial disease that starts in an early period of head injury. Chronic subdural hematoma did not present any signs or symptoms initially, except for the gradual occurrence of headache, but finally it presented signs of intracranial hypertension and focal signs. Chronic subdural hematoma in the hygroma-like period did not show any signs and symptoms. In the capsulated period, when changes in CT density suggested intracapsular hemorrhage, a heavy sensation of the head was noted. It was recognized as an abnormal feeling or a full sensation of the head. When the bleeding continued in the cavity, headache became continuous and focal signs gradually appeared. (author)

    There have been few reports on cerebral arteriovenous malformation (AVM) of newborns. We present here an interesting case of occult AVM diagnosed 17 years after an episode of acute subdural hematoma in the neonatal period. The cause of subdural hematoma had remained unclear and the patient had suffered from an intractable epilepsy of 17 years duration. Seizures were mainly characterized by drop attacks and included other seizure types such as complex partial seizure and generalized tonic clonic seizure. The symptoms had gradually become worse and the intervals between the occurrences of symptoms had become shorter. An interictal scalp EEG showed a focal spike in the left temporoparietal lobe. CT and MRI of that region demonstrated a porencephalic cyst which was supposed to have resulted from an old hematoma. There were no vascular abnormalities in angiography. Temporoparietal craniotomy and a corticogram were performed. The cortex with a focus was resected and the disappearance of a focal spike in the corticogram was confirmed during operation. Microscopically the cortex included AVM with gliosis. The initial postoperative course was good and seizures disappeared immediately after the operation. However, the symptoms of drop attacks observed before operation began to occur again 3 months later. The fact of postoperative recurrence suggests that the long history of the patient's seizures originating from AVM may have produced secondary epileptic foci. PMID:8677004

    Full Text Available Intramural duodenal hematoma is a rare cause of a proximal gastrointestinal tract obstruction. Presentation of intramural duodenal hematoma most often occurs following blunt abdominal trauma in children, but spontaneous non-traumatic cases have been linked to anticoagulant therapy, pancreatitis, malignancy, vasculitis and endoscopy. We report an unusual case of spontaneous intramural duodenal hematoma presenting as an intestinal obstruction associated with acute pancreatitis in a patient with established von Willebrand disease, type 2B. The patient presented with abrupt onset of abdominal pain, nausea, and vomiting. Computed tomography imaging identified an intramural duodenal mass consistent with blood measuring 4.7 cm × 8.7 cm in the second portion of the duodenum abutting on the head of the pancreas. Serum lipase was 3828 units/L. Patient was managed conservatively with bowel rest, continuous nasogastric decompression, total parenteral nutrition, recombinant factor VIII (humateP and transfusion. Symptoms resolved over the course of the hospitalization. This case highlights an important complication of an inherited coagulopathy.

  16. Intracranial Chronic Subdural Hematoma Presenting with Intractable Headache after Cervical Epidural Steroid Injection

    Postdural punctural headache (PDPH) following spinal anesthesia is due to intracranial hypotension caused by cerebrospinal fluid (CSF) leakage, and it is occasionally accompanied by an intracranial hematoma. To the best of our knowledge, an intracranial chronic subdural hematoma (CSDH) presenting with an intractable headache after a cervical epidural steroid injection (ESI) has not been reported. A 39-year-old woman without any history of trauma underwent a cervical ESI for a herniated nucleus pulposus at the C5-6 level. One month later, she presented with a severe headache that was not relieved by analgesic medication, which changed in character from being positional to non-positional during the preceding month. Brain magnetic resonance imaging revealed a CSDH along the left convexity. Emergency burr-hole drainage was performed and the headache abated. This report indicates that an intracranial CSDH should be considered a possible complication after ESI. In addition, the event of an intractable and changing PDPH after ESI suggests further evaluation for diagnosis of an intracranial hematoma. PMID:26361532

    Full Text Available Abstract Introduction Subarachnoid hemorrhages of spinal origin are extremely rare during pregnancy. We present the case of a patient with hemolytic anemia, elevated liver enzymes and low platelet count (the so-called HELLP syndrome, a potentially life-threatening complication associated with pre-eclampsia, who presented with an idiopathic spinal subarachnoid hematoma. Case presentation At 29 gestational weeks, a 35-year-old Japanese woman was diagnosed with HELLP syndrome based on bilateral leg paralysis, diminished sensation and reflexes, and laboratory findings. The pregnancy was immediately brought to an end by Cesarean delivery. Post-operatively, an MRI scan revealed a space-occupying lesion in her thoracic spinal canal. Emergency decompression was followed by total laminectomy. A subarachnoid hematoma, partially extending as far as the ventral side, was removed. After thorough washing and drain placement, the operation was completed with the suturing of artificial dura mater. Eight months post-operatively, her lower extremity sensation had improved to a score of 8 out of 10, but improvements in her muscular strength were limited to slight gains in her toes. MRI scans taken two months post-operatively revealed edematous spinal cord changes within her medulla. Conclusions A subarachnoid hematoma during pregnancy is extremely rare, possibly due to increased coagulability during pregnancy. However, this complication is potentially devastating should a clot compress the spinal cord or cauda equina. While several causes of hematoma have been proposed, we speculate that the factors underlying hemorrhagic diathesis in our case were the decreased platelet count characteristic of HELLP syndrome and vascular fragility due to elevated estrogen levels, in addition to increased abdominal pressure during pregnancy and pressure from the gravid uterus resulting in ruptured vessels around the spinal cord. In cases displaying a progressive lesion and severe neurological signs, prompt decompression is crucial.

    We present a very rare case of a patient with an infected subdural hematoma due to Propionibacterium acnes. A 63-year-old male complained of dizziness and was admitted to our hospital. He had a history of left chronic subdural hematoma due to a traffic accident, which had been conservatively treated. Physical, neurological and laboratory examinations revealed no definite abnormality. Plain CT scan demonstrated a hypodense crescentic fluid collection over the surface of the left cerebral hemisphere. The patient was diagnosed with chronic subdural hematoma and underwent burr hole surgery three times and selective embolization of the middle meningeal artery, but the lesion easily recurred. Repeated culture examinations of white sedimentation detected P. acnes. Therefore, he underwent craniotomy surgery followed by intravenous administration of antibiotics. The infected subdural hematoma was covered with a thick, yellowish outer membrane, and the large volume of pus and hematoma was removed. However, the lesion recurred again and a low-density area developed in the left frontal lobe. Craniotomy surgery was performed a second time, and two Penrose drainages were put in both the epidural and subdural spaces. Subsequently, the lesions completely resolved and he was discharged without any neurological deficits. Infected subdural hematoma may be refractory to burr hole surgery or craniotomy alone, in which case aggressive treatment with craniotomy and continuous drainage should be indicated before the brain parenchyma suffers irreversible damage.

    This work evaluated the potential of the isoforms of methamidophos to cause organophosphorus-induced delayed neuropathy (OPIDN) in hens. In addition to inhibition of neuropathy target esterase (NTE) and acetylcholinesterase (AChE), calpain activation, spinal cord lesions and clinical signs were assessed. The isoforms (+)-, (±)- and (-)-methamidophos were administered at 50mg/kg orally; tri-ortho-cresyl phosphate (TOCP) was administered (500mg/kg, po) as positive control for delayed neuropathy. The TOCP hens showed greater than 80% and approximately 20% inhibition of NTE and AChE in hen brain, respectively. Among the isoforms of methamidophos, only the (+)-methamidophos was capable of inhibiting NTE activity (approximately 60%) with statistically significant difference compared to the control group. Calpain activity in brain increased by 40% in TOCP hens compared to the control group when measured 24h after dosing and remained high (18% over control) 21 days after dosing. Hens that received (+)-methamidophos had calpain activity 12% greater than controls. The histopathological findings and clinical signs corroborated the biochemical results that indicated the potential of the (+)-methamidophos to be the isoform responsible for OPIDN induction. Protection against OPIDN was examined using a treatment of 2 doses of nimodipine (1mg/kg, i.m.) and one dose of calcium gluconate (5mg/kg, i.v.). The treatment decreased the effect of OPIDN-inducing TOCP and (+)-methamidophos on calpain activity, spinal cord lesions and clinical signs. PMID:22974967

    Full Text Available Sébastien Lobet,1,2 Cedric Hermans,1 Catherine Lambert1 1Hemostasis-Thrombosis Unit, Division of Hematology, 2Division of Physical Medicine and Rehabilitation, Cliniques Universitaires Saint-Luc, Brussels, Belgium Abstract: Hemophilia is a hematological disorder characterized by a partial or complete deficiency of clotting factor VIII or IX. Its bleeding complications primarily affect the musculoskeletal system. Hemarthrosis is a major hemophilia-related complication, responsible for a particularly debilitating chronic arthropathy, in the long term. In addition to clotting factor concentrates, usually prescribed by the hematologist, managing acute hemarthrosis and chronic arthropathy requires a close collaboration between the orthopedic surgeon and physiotherapist. This collaboration, comprising a coagulation and musculoskeletal specialist, is key to effectively preventing hemarthrosis, managing acute joint bleeding episodes, assessing joint function, and actively treating chronic arthropathy. This paper reviews, from a practical point of view, the pathophysiology, clinical manifestations, and treatment of hemarthrosis and chronic hemophilia-induced arthropathy for hematologists, orthopedic surgeons, and physiotherapists.

    Full Text Available Anemia caused by vitamin B12 deficiency resulting from inadequate dietary intake is rare in children in the modern era because of improvements in nutritional status. However, such anemia can be caused by decreased ingestion or impaired absorption and/ or utilization of vitamin B12. We report the case of an 18-year-old man with short stature, prepubertal sexual maturation, exertional dyspnea, and severe anemia with a hemoglobin level of 3.3 g/dL. He had a history of small bowel resection from 50 cm below the Treitz ligament to 5 cm above the ileocecal valve necessitated by midgut volvulus in the neonatal period. Laboratory tests showed deficiencies of both vitamin B12 and iron. A bone marrow examination revealed dyserythropoiesis and low levels of hemosiderin particles, and a cytogenetic study disclosed a normal karyotype. After treatment with parenteral vitamin B12 and elemental iron, both anemia and growth showed gradual improvement. This is a rare case that presented with short stature and delayed puberty caused by nutritional deficiency anemia in Korea.

  10. Chronic subdural hematoma fluid and its computerized tomographic density

    International Nuclear Information System (INIS)

    Laboratory and in vivo CT analysis were performed on 19 chronic subdural hematomas and five subdural hygromas. In these 25 hematoma samples, red blood cells (RBC), hematocrit, and hemoglobin (Hgb) varied greatly, though, these values correlated well with the CT densities. Plasma protein content was fairly constant with an average of 7.1+-0.8g/dl. There were four hematoma samples with RBC of less than 20x104?l or Hgb of less than 2.0g/dl. Their CT values ranged between 18 and 23 H.U., which were considered close to the in vivo serum level CT density. Five hygroma fluid showed no RBC and very little protein content of less than 0.4g/dl. CT density ranged between -2 and 13 H.U. The edge effect of the skull was experimentally studied using a phantom skull filled with water. This revealed a remarkable overshoot of the CT values within ten pixels from the inner wall of the skull. Visual observation of the original CT pictures revealed four low density hematomas and seven mixed density ones. When compared to the density of the ventricular cavity, all of the low density hematomas and the supernatant part of the mixed density ones were clearly higher in density. All five hygromas appeared CSF dense or lower. In conclusion, because of the edge effect by the skull, thin subdural fluids could not be diagnosed by CT alone. Thick subdural fluids could be differentiated as either hematoma or hygroma by their CT densities. Subdural hematomas had in vivo CT densities of at least serum level or approximately 20 H.U., while subdural hygromas had densities close to CSF. These characteristics were best appreciated by visual observation of the CT scan films. (J.P.N.)

In four of these 10 cases, the initial CT showed thin subdural collections of high density suggesting acute subdural hematoma. Two weeks later, the density of subdural collections reduced, but their volumes increased. Clinical symptoms such as headache and disorientation occurred three or four weeks later. Preoperative CT showed similar huge subdural collections of low density and marked mass effect. These cases underwent surgery from 24 to 44 days after injury, and development of neomembranes was confirmed. In the remaining six cases, the initial CT showed thin subdural collections of low density suggesting subdural hygroma. In five of the six cases, the density of the subdural collections was slightly higher than that of cerebrospinal fluid, and in one case, an area of spotted high density was shown. It was suggested that these were mixtures with blood. Follow-up CT scans revealed that the subdural collections increased in size but remained at a uniformly low density for the first month after the head injury, and then the increase in density occurred. Operations were performed 55 to 76 days after injury, and operative findings were not different from those of common chronic subdural hematoma. From these investigations, it was suggested that there were two types of evolution of chronic subdural hematoma. One is the development from acute subdural hematomas, and the other from subdural hygromas. It is supposed that blood and cerebrospinal fluid are very important factors in the evolution of subdural collections into chronic subdural hematomas.

  14. Spontaneous rupture of pedunculate gastric gastrointestinal stromal tumor into the gastrocelic ligament presenting as a stalked mass surrounded by loculated hematoma

    International Nuclear Information System (INIS)

    Gastric gastrointestinal stromal tumor (GIST) is one of the most common mesenchymal tumors of the stomach, which may be asymptomatic or cause symptoms such as pain, gastrointestinal bleeding, and obstruction. Hemoperitoneum due to spontaneous rupture of the tumor is an extremely rare complication. We described a case of a 52-year-old man with a large pedunculated GIST causing loculated hematoma within the gastrocolic ligament. The patient visited our hospital due to a 3 week history of epigastric pain. A computed tomography scan revealed a 10.3 x 7.5 x 9.4 cm sized mass that was growing exophytically from the greater curvature of the stomach and was surrounded by loculated hematoma within the gastrocolic ligament. Laparotomy revealed a large stalked gastric mass surrounded by loculated hematoma within the gastrocolic ligament and blood fluid in the peritoneal cavity. Pathologic examination confirmed a GIST, of the high risk group.

    Full Text Available Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones per [...] idurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica. Evolucionando favorablemente en los siguientes días. Discusión: Determinadas condiciones clínicas pueden influir en la aparición de un hematoma tras la realización de un bloqueo regional central: heparinas de bajo peso molecular, punciones dificultosas, cirugía vertebral previa, hepatopatías, fármacos, etc. El tratamiento quirúrgico en forma de laminectomía descompresiva realizada de forma precoz suele ser necesario y es el tratamiento de elección en muchas ocasiones, pero en determinadas condiciones como la que nos ocupa, sin síntomas compresivos, sin un carácter progresivo o bien que estos disminuyan rápidamente, puede optarse por un tratamiento conservador en forma de analgesia y corticoterapia, siempre bajo un estricto control que permita actuar de forma rápida ante cualquier eventualidad negativa en su evolución. Abstract in english Introduction: Epidural hematoma secondary to neuroaxial anesthesia is a rare complication, but highly relevant due to its clinical and medico-legal implications. According to some authors, its incidence can reach 1/190,000-1/200,000 for peridural punctures and 1/320,000 for spinal punctures. Early d [...] iagnosis and treatment within the first 6-12 hours is the main aspect related to its therapeutic management. However, in some cases such as the one reported here, surgery is not required and the patient can be managed with a conservative treatment. Clinical case: A 73-year-old patient, ASA IV, with a history of cirrhosis associated to portal hypertension, hypersplenism, COPD, obesity, hypertensive cardiopathy and tricuspid failure. He was scheduled for prostate alcoholization after ruling out surgery. Preoperative blood analyses showed a prothrombin activity of 80% and 90,000 platelets. Several failed attempts of spinal puncture were done, but general anesthesia was finally required with spontaneous ventilation through laryngeal mudpack, propofol, fentanyl and sevoflurane. Clinical manifestations appeared after 36 hours, with non-irradiated severe lumbar pain and plantar cutaneous areflexia. The presence of epidural hematoma at the L1-L4 level was confirmed through NMR. Given the absence of flaccid paraparesis, sphincter involvement or other sensitive-motor signs and after consultation with the Rachis Unit and the Neurology Service, a conservative treatment an

    Full Text Available Trauma craniocerebral é uma causa frequente de mortalidade e comprometimento neurológico adquirido em crianças. No entanto, hematomas epidurais (HED) são raros em pacientes pediátricos, com poucas series estudando a evolução destes pacientes. Neste estudo, os autores apresentam os resultados de uma [...] casuística de pacientes com HED acompanhados em longo prazo. MÉTODO: Entre janeiro de 2006 e dezembro de 2008, 49 pacientes com HED foram tratados em nossa unidade. Curso clínico, achados radiológicos, e resultados foram avaliados. O estado neurológico foi avaliado com o Glasgow Coma Scale (GCS). A idade variou de 1 dia a 16 anos. A média de acompanhamento foi de 6 meses. RESULTADOS: Na admissão, a maioria dos pacientes apresentava trauma leve e 57% estavam com GCS de 13-15. O sintoma mais comum foi irritabilidade. Os mecanismos de trauma mais frequentes foram queda de altura em 29 casos e acidentes de trânsito em 16 casos. Três destes pacientes apresentavam GCS 3, mas somente um morreu. Verificou-se déficit neurológico tardio em nove pacientes. CONCLUSÃO: Esta lesão pode ocorrer após traumas leves e em crianças alerta com exames neurológicos não focais. No entanto, em crianças com irritabilidade com hematoma subgaleal e história de perda de consciência, tomografia do crânio deve ser realizada. Abstract in english Traumatic head injury is a common cause of mortality and acquired neurological impairment in children. However, pediatric epidural hematomas (EDHs) are not common and few series have studied the evolution of these patients.

METHOD: Between January 2006 and December 2008, 49 patients with traumatic EDH were treated at our unit. Clinical course, radiological findings and outcomes were evaluated. Neurological status was assessed using the Glasgow Coma Scale (GCS). The patients' ages ranged from one day to 16 years. The mean follow-up was six months. RESULTS: On admission, most of the patients presented mild trauma and 57% had a GCS of 13-15. The most common symptom was irritability. The most frequent mechanisms of injury were: falling from a height in 29 cases and motor vehicle accidents in 16 cases. Three of these patients presented GCS 3, but only one died. We found a late neurological deficit in nine patients. CONCLUSION: These lesions may occur following mild head trauma and in alert children with nonfocal neurological examinations. However, in children presenting irritability with subgaleal hematomas and a history of loss of consciousness, skull computed tomography must be performed.

    Sometimes chronic subdural hematoma can be developed following posttraumatic subdural hygroma. The purpose of this study is to investigate its incidence, the duration required for their conversion, and characteristic CT and MR findings of subdural hygroma and chronic subdural hamatoma. We studied 8 patients with persistent posttraumatic subdural hygroma which consequently developed chronic subdural hamatoma. The patients were examined with CT initially and followed-up with CT in 3 and MR in 5. We analyzed the location of the lesion, the change of the density or signal intensity, the change of the size, and the degree of enhancement and mass effect. The duration required for the formation of hematoma was 48-166 days (mean, 76 days). The characteristic CT findings of subdural hygroma were a crescentric lesion with CSF density along the inner table with-out contrast enhancement. The mass effect was minimal. The CT findings of chronic subdural hematoma were higher density than that of hygroma in all cases, increase in thickness and size in 3 cases, and contrast enhancement along the inner membrane of the hematoma in 5 cases. The signal intensities of the subdural hygroma were identical to those of CSF on both T1 and T2 weighted images, whereas, those of chronic subdural hamatoma were higher. The increased signal intensity on T1 weighted MR images and increased attenuation or contrast enhancement of the lesion on CT may suggest the conversion of subdural hygroma into chronic subdural hematoma.

    Full Text Available Spontaneous subcapsular renal hematoma is not a common entity. We report a 38-year-old lady presenting with sudden onset right flank pain with uncontrolled hypertension and she was found to have subcapsular collection in the right kidney on ultrasonography. Finding was confirmed on computed tomography. Except hypertension, no particular cause for the condition could be found. Symptoms and size of the collection decreased on conservative treatment. They completely disappeared on ultrasonography at 6 months follow-up. She was asymptomatic at 18 months follow-up.

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

    We describe the case of a patient with an intramural hematoma and floating thrombus after cardiopulmonary resuscitation. The 92-year old man had a cardiac arrest due to ventricular fibrillation and witnesses immediately initiated manual cardiopulmonary resuscitation. Transesophageal echocardiography was performed immediately on hospital admission because the patient was in cardiogenic shock. In addition to an akinetic anterior wall, examination of the descending thoracic aorta demonstrated an intramural hematoma and a floating intra-aortic thrombus at a distance of 40cm from the dental arch. There was no aortic dissection. The thrombus was attributed to aortic compression during cardiopulmonary resuscitation. Although the aortic thrombus and intramural hematoma were not associated with any complications in this patient, insertion of an intra-aortic balloon may have led to aortic rupture or embolic events. Transesophageal echocardiography should be performed, when available, prior to insertion of an intra-aortic balloon for counterpulsation in patients who have undergone cardiopulmonary resuscitation.

    Full Text Available We report successful outcome of a huge post- trabeculectomy intra-bleb hematoma and hyphema that occurred following digital ocular compression. The patient was a 64-year-old lady suffering from bilateral primary angle closure glaucoma and cataract. She was on anti-platelet therapy. She underwent single-site phacoemulsification, intra-ocular lens implantation and trabeculectomy with mitomycin C in the right eye. The trabeculectomy was under-filtering. She was asked to perform digital ocular compression thrice daily. On 15 th post-operative day, she presented with a huge intra-bleb hematoma and hyphema. The hematoma did not respond to conservative measures and was drained to prevent bleb failure. We recommend caution in the consideration of digital ocular compression in patients on prophylactic anti-coagulation.

    Full Text Available El hematoma subdural crónico constituye una enfermedad frecuente en la práctica neuroquirúrgica cotidiana. Su diagnóstico se realiza actualmente de forma temprana en la mayoría de los pacientes, a partir de la introducción de las modernas técnicas de imagenología. Se presenta el caso de un enfermo de 84 años de edad con historia de cefalea, mutismo acinético y cuadriparesia, cuyo examen tomográfico mostró una colección extraxial supratentorial hemisférica derecha con calcificación masiva; se practicó la exéresis mediante una craneotomía y el estudio histopatológico confirmó el diagnóstico de hematoma subdural crónico. Se concluye que, al constituir la calcificación masiva del hematoma subdural crónico una rara forma de presentación imagenológica en la actualidad, deben contemplarse otras entidades en el diagnóstico diferencial como neoplasias y malformaciones vasculares intracraneales; por otro lado, aumenta la complejidad quirúrgica ya que es imprescindible la práctica de una craneotomía para la evacuación de la lesión.

  5. CT findings and the evaluation of chronic subdural hematoma, (1)

    International Nuclear Information System (INIS)

    CT examinations were performed in 621 cases of minor head injury within 3 days, and 26 cases (4%) exhibited hygroma-like CT findings. These 26 cases were divided into two patterns: Type A (12 cases) and Type B (14 cases). Type A showed smooth thin hygroma-like low density area beneath the skull with compression of the cerebral surface and cerebral sulci. Type B showed an irregular thin hygroma-like low density area beneath the skull with recognized cerebral sulci. Many of these cases changed into chronic subdural hematomas, i.e. Twelve cases (100%) of Type A and three cases (21%) of Type B changed into chronic subdural hematomas. It is highly possible to forecast the subsequent occurrence of the chronic subdural hematomas soon after a head injury. (author)

    Freeman-Sheldon syndrome, or distal arthrogryposis type 2A (DA2A), is an autosomal-dominant condition caused by mutations in MYH3 and characterized by multiple congenital contractures of the face and limbs and normal cognitive development. We identified a subset of five individuals who had been putatively diagnosed with “DA2A with severe neurological abnormalities” and for whom congenital contractures of the limbs and face, hypotonia, and global developmental delay had resulted in early death in three cases; this is a unique condition that we now refer to as CLIFAHDD syndrome. Exome sequencing identified missense mutations in the sodium leak channel, non-selective (NALCN) in four families affected by CLIFAHDD syndrome. We used molecular-inversion probes to screen for NALCN in a cohort of 202 distal arthrogryposis (DA)-affected individuals as well as concurrent exome sequencing of six other DA-affected individuals, thus revealing NALCN mutations in ten additional families with “atypical” forms of DA. All 14 mutations were missense variants predicted to alter amino acid residues in or near the S5 and S6 pore-forming segments of NALCN, highlighting the functional importance of these segments. In vitro functional studies demonstrated that NALCN alterations nearly abolished the expression of wild-type NALCN, suggesting that alterations that cause CLIFAHDD syndrome have a dominant-negative effect. In contrast, homozygosity for mutations in other regions of NALCN has been reported in three families affected by an autosomal-recessive condition characterized mainly by hypotonia and severe intellectual disability. Accordingly, mutations in NALCN can cause either a recessive or dominant condition characterized by varied though overlapping phenotypic features, perhaps based on the type of mutation and affected protein domain(s).

  9. Dynamic/statis brain scintigraphy: an effective screening test for subdural hematoma

    International Nuclear Information System (INIS)

    Dynamic /sup 99m/Tc-pertechnetate perfusion scintigraphy of the brain was coupled with the delayed static scan in 5,853 studies as a screening test for neurological disease. Of approximately 1,000 patients referred for investigation for possible subdural hematoma (SDH), 23 proved to have SDH at surgery. Their scintigraphic abnormalities were analyzed and classified. When neither study indicates abnormality, angiography is not required, as SDH is unlikely. When the scintigraphic appearance is characteristic of SDH, angiography or surgical exploration is mandatory, since SDH is probably present. When the scintigraphic findings are consistent with but not typical of SDH, the study remains useful as a screening procedure, but the decision to proceed with angiography is based primarily on the neurological course.

    Duodenal intramural hematoma (DIH) usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders. PMID:26697240

In one patient, permanent loss of vision was involved, but with the other patient, we were able to prevent this by performing immediate decompression after definite diagnosis. We present our clinical experience with regard to the treatment process and method for prevention of retrobulbar hematoma using a scalp vein set tube and a negative pressure drainage system.

    Full Text Available Intracranial rhabdomyosarcoma is a very rare disorder. Subdural rhabdomyosarcoma has not been reported yet. It can be misdiagnosed with chronic subdural hematoma in CT images. Herein, we presented a 2.5-year-old boy with intractable chronic subdural hematoma who were treated with burr hole insertion, needle aspiration and shunting for about 2 years with partial resolution of his symptoms after each procedure. The final pathologic evaluation after extensive bilateral craniotomy revealed rhabdomyosarcoma. The role of CT and MRI in early diagnosis and management of this rare situation is discussed.

    An otherwise healthy 28-year old male presented to his general practitioner with dyspnoea in the morning and abdominal discomfort through months. Four months earlier, he had experienced a blunt trauma to the left side of his abdomen. Abdominal ultrasonography revealed a splenic hematoma and the patient was admitted to hospital. Vital signs were normal, and blood samples revealed a marginal anaemia and elevated C-reactive protein, but were otherwise normal. Computed tomography showed an 18 centimetre wide splenic hematoma. The patient was referred to another hospital for conservative treatment in the outpatient clinic.

  14. Hematoma epidural secundario a anestesia espinal: Tratamiento conservador Epidural hematoma secondary to spinal anesthesia: Conservative treatment

    Full Text Available Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones peridurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica. Evolucionando favorablemente en los siguientes días. Discusión: Determinadas condiciones clínicas pueden influir en la aparición de un hematoma tras la realización de un bloqueo regional central: heparinas de bajo peso molecular, punciones dificultosas, cirugía vertebral previa, hepatopatías, fármacos, etc. El tratamiento quirúrgico en forma de laminectomía descompresiva realizada de forma precoz suele ser necesario y es el tratamiento de elección en muchas ocasiones, pero en determinadas condiciones como la que nos ocupa, sin síntomas compresivos, sin un carácter progresivo o bien que estos disminuyan rápidamente, puede optarse por un tratamiento conservador en forma de analgesia y corticoterapia, siempre bajo un estricto control que permita actuar de forma rápida ante cualquier eventualidad negativa en su evolución.Introduction: Epidural hematoma secondary to neuroaxial anesthesia is a rare complication, but highly relevant due to its clinical and medico-legal implications. According to some authors, its incidence can reach 1/190,000-1/200,000 for peridural punctures and 1/320,000 for spinal punctures. Early diagnosis and treatment within the first 6-12 hours is the main aspect related to its therapeutic management. However, in some cases such as the one reported here, surgery is not required and the patient can be managed with a conservative treatment. Clinical case: A 73-year-old patient, ASA IV, with a history of cirrhosis associated to portal hypertension, hypersplenism, COPD, obesity, hypertensive cardiopathy and tricuspid failure. He was scheduled for prostate alcoholization after ruling out surgery. Preoperative blood analyses showed a prothrombin activity of 80% and 90,000 platelets. Several failed attempts of spinal puncture were done, but general anesthesia was finally required with spontaneous ventilation through laryngeal mudpack, propofol, fentanyl and sevoflurane. Clinical manifestations appeared after 36 hours, with non-irradiated severe lumbar pain and plantar cutaneous areflexia. The presence of epidural hematoma at the L1-L4 level was confirmed through NMR. Given the absence of flaccid paraparesis, sphincter involvement or other sensitive-motor signs and after consultation with the Rachis Unit and the Neurology Service, a conservative treatment and an expecting attitude were agreed based on analgesia and strict neurological monitoring, both clinical and radiological. The evolution of the patient was favorable in the next days. Discussion: Certain clinical conditions can affect the appearance of hematoma after performing a central regional blockade: low molecular weight heparins, difficult punctures, previous vertebral surgery, hepatopathies, drugs, etc. Early surgical treatment based on decompression laminectomy is usually required and it is the treatment agreed in many cases, but in some patients such as this one, with no compressive symptoms, no progression of symptoms or a rapid improvement of symptoms, a conservative treatment based on analgesia and corticotherapy can be decided, always with a strict control in order to allow a quick intervention if there is a negative event in the evolution of the patient.

    Genetic studies of intellectual disability and identification of monogenic causes of obesity in humans have made immense contribution toward the understanding of the brain and control of body mass. The leptin > melanocortin > SIM1 pathway is dysregulated in multiple monogenic human obesity syndromes but its downstream targets are still unknown. In ten individuals from six families, with overlapping 6q16.1 deletions, we describe a disorder of variable developmental delay, intellectual disability, and susceptibility to obesity and hyperphagia. The 6q16.1 deletions segregated with the phenotype in multiplex families and were shown to be de novo in four families, and there was dramatic phenotypic overlap among affected individuals who were independently ascertained without bias from clinical features. Analysis of the deletions revealed a ?350 kb critical region on chromosome 6q16.1 that encompasses a gene for proneuronal transcription factor POU3F2, which is important for hypothalamic development and function. Using morpholino and mutant zebrafish models, we show that POU3F2 lies downstream of SIM1 and controls oxytocin expression in the hypothalamic neuroendocrine preoptic area. We show that this finding is consistent with the expression patterns of POU3F2 and related genes in the human brain. Our work helps to further delineate the neuro-endocrine control of energy balance/body mass and demonstrates that this molecular pathway is conserved across multiple species. PMID:26833329

    Mutations in more than a hundred genes have been reported to cause X-linked recessive intellectual disability (ID) mainly in males. In contrast, the number of identified X-linked genes in which de novo mutations specifically cause ID in females is limited. Here, we report 17 females with de novo loss-of-function mutations in USP9X, encoding a highly conserved deubiquitinating enzyme. The females in our study have a specific phenotype that includes ID/developmental delay (DD), characteristic facial features, short stature, and distinct congenital malformations comprising choanal atresia, anal abnormalities, post-axial polydactyly, heart defects, hypomastia, cleft palate/bifid uvula, progressive scoliosis, and structural brain abnormalities. Four females from our cohort were identified by targeted genetic testing because their phenotype was suggestive for USP9X mutations. In several females, pigment changes along Blaschko lines and body asymmetry were observed, which is probably related to differential (escape from) X-inactivation between tissues. Expression studies on both mRNA and protein level in affected-female-derived fibroblasts showed significant reduction of USP9X level, confirming the loss-of-function effect of the identified mutations. Given that some features of affected females are also reported in known ciliopathy syndromes, we examined the role of USP9X in the primary cilium and found that endogenous USP9X localizes along the length of the ciliary axoneme, indicating that its loss of function could indeed disrupt cilium-regulated processes. Absence of dysregulated ciliary parameters in affected female-derived fibroblasts, however, points toward spatiotemporal specificity of ciliary USP9X (dys-)function. PMID:26833328

    Background Secondary brain stem injury is associated with transtentorial herniation, and manifests as “Duret” hemorrhages. Such an injury has been considered a terminal brain stem event with a high morbidity and mortality, sometimes discouraging continuation of care. However, there have been rare instances where patients have had reasonable recovery. We report another case, emphasizing that such an injury by itself should not deter aggressive measures, as good outcomes remain a possibility. Case presentation A 37-year-old male sustained a right subdural hematoma after a mechanical fall while intoxicated. He presented initially with a Glasgow Coma Scale 15. Three days later, he exhibited acute neurological deterioration to Glasgow Coma Scale 4, requiring intubation and mannitol. Repeat scan demonstrated enlarging right subdural hematoma with worsening shift; brain stem hemorrhage was noted at pontomesencephalic junction. Patient was immediately taken for subdural hematoma evacuation. The following day, patient was able to sluggishly follow commands in all four extremities. He had a short stay for inpatient rehabilitation and underwent autologous cranioplasty at 3 months. On examination, he was awake, alert, and oriented to self, time, and location; he exhibited dysarthric speech, right ptosis, but followed commands in all four extremities with no focal motor weakness. Conclusion In contrast to the common belief, patients suffering from a “Duret” hemorrhage can still have a good outcome. “Duret” hemorrhages may not represent a fatal injury. The finding from this paper suggests the finding of “Duret” hemorrhages on imaging should not deter aggressive measures especially in patients with lesions causing significant mass effects. Overall clinical status should drive surgical options and clinical course. PMID:26869816

  20. Diffusion-weighted imaging provides support for secondary neuronal damage from intraparenchymal hematoma

    International Nuclear Information System (INIS)

    It is controversial whether an intracerebral hematoma (ICH) causes ischemia of surrounding brain. By virtue of its high sensitivity to acute cerebral infarction, diffusion-weighted imaging (DWI) helps answer this question. We used this technique to assess the parenchyma surrounding ICH for restricted diffusion. Echoplanar DWI (b 1000 s/mm2) and conventional MRI sequences were performed in 30 subjects (symptom duration 7-75 h) with primary ICH, mean volume: 13±15 cm3. We calculated mean apparent diffusion coefficients (ADC) within high signal regions around the hematoma on DWI or T2-weighted images and within the ICH itself, comparing them to the contralateral brain. We used the Student's t -test to examine for differences between these regions and linear regression to relate changes to the age of the ICH. A thin rim of high signal on DWI and a wider rim on T2-weighted images surrounded all hematomas. The ADC within the rim on DWI showed a maximum reduction of 40%, in two patients imaged within 10 h of symptom onset. They rose during the first day (r2=0.84; P 2=0.5; P <0.03). The rim on T2-weighting showed a mean increase of 50% and ADC within the ICH were reduced by a mean of 38%; these variations showed no relationship with ICH age and no group showed any relationship with ICH size. The ADC within the three regions was significantly different from each other. The presence of restricted diffusion in the parenchyma surrounding ICH provides support for secondary neuronal damage.

    Full Text Available Spontaneous spinal epidural hematoma (SSEH is a rare entity.SSEH is an accumulation of blood in the vertebral epidural space in the absence of trauma or iatrogenic procedure like lumbar puncture.The incidence of SSEH has been estimated at 0.1 patients per 100,000 individuals and represents less than 1% of spinal space-occupying lesions .Here we are presenting case of a 65year old female hypertensive on treatment with controlled blood pressure, who presented with sudden onset paraplegia and weakness of muscles of hand, associated with urinary and bowel incontinence that started 6 hours before presenting to Emergency Room .Patient was subjected to MRI spine that revealed a collection in spinal epidural space ,hypointense in T1W images and hyperintense in T2W images, extending from C6-C7 to T1-T2 suggestive of acute / subacute epidural hematoma (fig 1.In our case all possible causes of an epidural haematoma were ruled out by relevant investigations.Patient was subjected to surgical evacuation of hematoma after 48 hours of presentation.Perioperative and Postoperative period was uneventfull . Sensations over involved areas improved. Motor weakness also improved from Grade III to Grade IV+ in bilateral lower limbs and from Grade II to Grade IV in small muscles of hand and triceps, however Patient persisited with urinary incontinence.CONCLUSION: When a patient receiving anticoagulant therapy complains of sudden and unexplained neck or back pain, we should suspect the possibility of SSEH. For early diagnosis, immediate MRI is essential .In addition, we should consider SSEH as one of the important differential diagnoses in elderly patients who have developed acute myelopathy.

  10. Magnetic resonance imaging of hematomas in a 0.02 T magnetic field

    International Nuclear Information System (INIS)

    One intramuscular calf hematoma, 2 ankle hematomas and 4 cephalhematomas were imaged at various ages in a low magnetic field (0.02 T). At least one spin echo (SE) multislice image and a series of inversion recovery images (IR) were made varying the inversion time for estimation of the relaxation time T1. T1 tended to shorten and T2 to stay unchanged. With an unsuitable pulse sequence the hematomas were not visible. They were best seen with short TIs. The images of one of the ankle hematomas and the calf hematoma were compared with sonographic findings. The appearances of the hematomas varied during aging with both imaging modalities. The hematomas were easier to detect with magnetic resonance imaging than with ultrasound, also when aging. (orig.)

    Full Text Available Resumo Introdução: o hematoma subdural crônico (HSDC) é uma doença relativamente comum em adultos com mais de 60 anos. Sua apresentação clínica clássica é uma síndrome neurológica focal progressiva com sinais e sintomas de hipertensão endocraniana, em pacientes que de maneira geral tem antecedentes [...] de traumatismo craniano (TEC) nas duas ou três semanas anteriores à consulta. No entanto, o HSDC pode se apresentar sob diferentes formas o que dificulta seu diagnóstico. Material e métodos: são analisados os aspectos clínicos de 63 pacientes portadores de HSDC que consultaram no Hospital de Tacuarembó em um período de 59 meses. Resultados: os pacientes tinham entre 30 e 88 anos sendo 73% do sexo masculino; 67% tinham antecedentes de TEC. A apresentação mais freqüente foi um quadro progressivo de déficit focal ou hipertensão endocraniana. Em dois casos o déficit foi brusco, simulando um ataque cerebrovascular. Em três pacientes não havia registro de antecedente traumático e clinicamente se propôs um processo tumoral expansivo. Em 11 casos os sintomas iniciais foram da esfera neuropsíquica, simulando uma "demência". Em 18 casos houve depressão de vigília, sendo brusca em cinco, levando a proposição de um ataque cerebrovascular hemorrágico ou isquêmico. Em seis pacientes o sintoma mais destacado era cefaléia permanente sem outros sinais ou sintomas. Conclusões: a HSDC pode se apresentar com distintas "máscaras clínicas", simulando processos expansivos tumorais, ataques cerebrovasculares hemorrágicos ou isquêmicos, ataques isquêmicos transitórios ou demências. Em pessoas com mais de 60 anos com um quadro progressivo e de instalação insidiosa, mesmo com ausência de traumatismo craniano, deve-se suspeitar desta patologia.

Conclusiones: el HSDC puede presentarse con distintas "máscaras clínicas", simulando procesos expansivos tumorales, ataques cerebrovasculares hemorrágicos o isquémicos, ataques isquémicos transitorios o demencias. Se debe entonces tener un alto índice de sospecha de esta enfermedad frente a individuos mayores de 60 años con un cuadro progresivo y de instalación insidiosa aun en ausencia de traumatismo de cráneo Abstract in english Summary Background: chronic subdural hematoma (CSDH-HSDC) is a relatively common disease in adults older than 60 years.

    By revealing the relation between dilation of a subsurface fracture due to pressurization and travel time delay, it may be possible to measure the information as to the subsurface fracture system as a geothermal reservoir. In this study, field experiment was conducted to clarify the relation between the travel time delay of elastic waves and the dilation of fracture, pressure, and incident angles. The travel time delay of P-wave and S-wave tended to increase with the pressurization. When incident angle was about 90{degree} against the fracture, the increase was ranging between 0 and 0.2 ms. The magnitude of this delay could not be explained only by the opening of main fracture. It was considered that there were micro-crack zones around the main fracture. The difference of P-S delay depended on the pressurization and change of the pressure. The delay depended on the incident angle against the fracture. The delay of S-wave showed the polarized wave direction dependency. However, the obtained results might greatly depend on the analytical method and parameters. 4 refs., 10 figs.

    Sickle-cell disease is common among patients of Afro-Caribbean origin. Though it can precipitate neurological conditions, it only rarely causes neurosurgical problems, with very few reported cases. We describe the case of a 7-year-old girl with a background of sickle-cell disease (SCD) brought into an acute neurosurgical unit in extremis, signs of a raised ICP, and with no history of recent trauma. Following further investigations, an acute drop in the hemoglobin and hematocrit levels were noted, with the cause of her presentation being attributed to a sickling crisis causing skull convexity infarction and resulting in spontaneous bilateral extradural hematomas requiring emergency evacuation. We review the current literature and propose the pathophysiological mechanism behind this phenomenon. PMID:26374442

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O hematoma associado à compressão espinhal após anestesia peridural é uma complicação neurológica grave, apesar da pequena incidência relatada (1:150.000. É um episódio agudo, e o tratamento tradicionalmente aplicado é a descompressão cirúrgica de urgência. Mais recentemente, em casos específicos, o tratamento com corticosteróide tem sido aplicado como alternativa, com boa recuperação neurológica. O objetivo deste relato foi expor um caso de hematoma peridural com tratamento conservador e recuperação neurológica completa. RELATO DO CASO: Paciente do sexo feminino, 34 anos, estado físico ASA I, sem qualquer histórico de coagulopatia ou terapia anticoagulante, submetida à anestesia peridural com punção única, em L2-L3, para tratamento cirúrgico de varizes nos membros inferiores. Oito horas após a anestesia regional, ela ainda apresentava bloqueio motor completo (escala de Bromage, redução das sensibilidades térmica e dolorosa abaixo do nível L3, hiperalgesia na região plantar esquerda, preservação dos reflexos tendinosos e ausência de dor lombar. A tomografia computadorizada revelou hematoma peridural em L2 com compressão do saco dural. Dez horas após a punção peridural não havia progressão dos sinais e sintomas neurológicos. Optou-se, então, pelo tratamento com metilprednisolona em infusão venosa contínua (5,3 mg.kg-1 na primeira hora e 1,4 mg.kg-1.h-1 nas 23 horas subseqüentes. Oito horas após o início do tratamento, a paciente recuperou as sensibilidades térmica e dolorosa, e houve regressão total do bloqueio motor. Na 12ª hora, deambulava e referia dor na ferida operatória. O hematoma peridural não foi visualizado em nova tomografia computadorizada na 14ª hora após o início do tratamento.

    Full Text Available The clinical manifestation of chronic subdural hematoma is not limited to neurological deficits or cognitive impairment. It may present with behavioral abnormalities. When the behavioral abnormalities present without obvious neurological deficits and in the absence of trauma, it leads to misdiagnosis. A trivial trauma may cause intracranial bleed that is either missed or ignored in the clinical history. This case report highlights the clinical picture of a homeless patient who presented with withdrawn and disorganized behavior, apathy and poverty of speech in the absence of any neurological deficit. His clinical presentation led to a possibility of psychosis and he was started on antipsychotics. He had developed extrapyramidal side effects in low dose of antipsychotic without any clinical benefit in his clinical picture. Neuroimaging done to rule out any possible organicity-revealed bilateral subdural hematoma, which was later evacuated by neurosurgical intervention in multiple settings and the patient had improved. This case report unfolds the mystery behind the psychotic presentation in a homeless adult.

    Introduction Spontaneous epidural hematoma of the spine (SEHS) is an extremely rare entity. Patients known to have thrombophilia or on anticoagulant drugs are the most affected. It is generally caused by a rupture of the postero-internal vertebral venous plexus secondary to minor barotrauma such as cough, peridural catheter insertion... Early diagnosis and treatment showed to have the best outcome. Cases report We report 3 cases of spontaneous epidural hematoma in patients treated by acenocoumarol, which occurred without any provocative factor. All 3 patients were treated with decompressive laminectomy. Discussion We described the MRI findings and discussed the spontaneity of the entity. Our present case studies and the review of the literature showed that early diagnosis and management of SEHS can lead to improvement of the neurological state and avoid definitive motor and sensitive deficit. Conclusion This rare entity should be suspected in every acute medullary syndrome with spinal pain, motor and/or sensory deficit. In order to decrease the sequelae, neurologically unstable patients should benefit from early diagnosis and urgent surgical decompression. PMID:26074484

    A facet cyst is a very rare condition in the thoracolumbar spine and more so, hemorrhage into a cyst is extremely rare. We present a case of a facet cyst hematoma in the T12-L1 spine. A 69-year-old woman complained of chronic back pain with right lower extremity pain, and weakness for 3 years. MRI and MR myelography showed an extradural mass at the T12-L1 level with heterogeneous signal intensity on both T1-and T2-weighted images, which was continuous to the right T12-L1 facet joint. The neighboring facet joint showed severe degeneration on the CT scan. The mass a was simple hematoma covered with a thin fibrous membrane and connected with facet joint macroscopically and microscopically. The pathogenesis of the facet cyst hematoma is not clear but it can compress nerve roots or dura mater and cause radiculopathy or cauda equina syndrome. Surgical removal should be recommended for symptomatic relief.

    Chronic subdural hematomas (CSDHs) typically present with cognitive dysfunction and a history of trauma. Localized dural enhancement on postcontrast MRI scans associated with the surrounding membrane has been described in CSDH. We present an 83-year-old man with rapidly progressing cognitive dysfunction 4 weeks after head trauma related to a fall. MRI showed CSDHs, which in addition to localized dural gadolinium enhancement, showed a marked diffuse, symmetric, contiguous pachymeningeal enhancement of the supratentorial and infratentorial intracranial dural mater. Meningeal biopsy failed to disclose an infectious or neoplastic cause of the enhancement and instead showed fibrocollagenous change. We conclude that diffuse dural enhancement on MRI scans associated with CSDH cause does not necessarily indicate a superimposed process such as infection or malignancy. CSDH should be considered in the differential diagnosis of diffuse dural enhancement, especially when supported by appropriate clinical findings. PMID:15050219

Ao ser admit [...] ido no hospital, o paciente apresentava-se em choque cardiogênico, sendo, então, imediatamente submetido a ecocardiografia transesofágica. Além de uma parede anterior acinética, o exame da aorta torácica descendente mostrou um hematoma intramural e um trombo intra-aórtico flutuante a uma distância de 40cm do arco dental. Não havia dissecção da aorta. O trombo foi atribuído à compressão aórtica durante a ressuscitação cardiopulmonar. Embora o trombo aórtico e o hematoma intramural não tenham se associado a qualquer complicação nesse paciente, a inserção de um balão intra-aórtico poderia ter levado a uma ruptura da aorta ou a eventos embólicos.

Abstract in english We describe the case of a patient with an intramural hematoma and floating thrombus after cardiopulmonary resuscitation. The 92-year old man had a cardiac arrest due to ventricular fibrillation and witnesses immediately initiated manual cardiopulmonary resuscitation. Transesophageal echocardiography [...] was performed immediately on hospital admission because the patient was in cardiogenic shock. In addition to an akinetic anterior wall, examination of the descending thoracic aorta demonstrated an intramural hematoma and a floating intra-aortic thrombus at a distance of 40cm from the dental arch. There was no aortic dissection. The thrombus was attributed to aortic compression during cardiopulmonary resuscitation. Although the aortic thrombus and intramural hematoma were not associated with any complications in this patient, insertion of an intra-aortic balloon may have led to aortic rupture or embolic events. Transesophageal echocardiography should be performed, when available, prior to insertion of an intra-aortic balloon for counterpulsation in patients who have undergone cardiopulmonary resuscitation.

    Subcapsular hematoma of the liver represents an unusual clinical phenomenon in the pregnancy and postpartum period with serious complications in terms of fetal and maternal mortality. Here we report a case of a 32-year-old primiparous female at 36 weeks of gestation, admitted to a maternity ward of a private clinic for preeclampsia. The woman underwent an emergency caesarean section with the extraction of an alive foetus. A few hours after delivery, she was transferred to the emergency department of our institution complaining of severe epigastric pain. Diagnostic work-up was suggestive of a subcapsular right lob hepatic hematoma which was successfully managed conservatively. Timely diagnosis is necessary for the prevention of life-threatening events in mother and fetus. For this reason acute care physicians have to be vigilant of the condition and consider this in the differential diagnosis of epigastric pain during pregnancy and postpartum. PMID:25202460

  3. MR imaging evaluation of subdural hematomas in child abuse

    International Nuclear Information System (INIS)

    MR imaging is the most accurate modality for determining the presence, number, and aging of subdural hematomas. Based on seven patients studied with CT and MR imaging, MR imaging should be the gold standard in child abuse evaluations. Since the history of child abuse is often ambiguous, MR imaging can assist in dating when the injury occurred. MR imaging in two perpendicular planes is needed, with one plane having both T1- and T2-weighted sequences. Chronic subdural hematomas on CT often have the same density as cerebrospinal fluid and may be misdiagnosed as atrophy or unrecognized. Therefore, the child may be returned into a dangerous situation and subjected to recurrent episodes of battering

    Although arachnoid cysts (ACs) are associated with chronic subdural hematomas (CSDHs), especially in young patients, the detailed features of CSDHs associated with ACs remain poorly understood. The objective of this study was to clarify the relationship between the location of CSDHs and ACs and the significance of ACs in young patients with CSDHs. We retrospectively assessed 605 consecutive patients 7 years of age and older who were diagnosed with a CSDH between 2002 and 2014. Twelve patients (2%) had ACs, and 10 of the 12 patients were 7–40 years of age. Patients with ACs as a complication of CSDHs were significantly younger than those without ACs (p < 0.05). Three different relationships between the location of CSDHs and ACs were found: a CSDH contacting an AC, an ipsilateral CSDH apart from an AC, and a CSDH contralateral to an AC. In 21 patients with CSDHs who were 7–40 years of age, 10 (47.6%) had ACs (AC group) and 7 (33.3%) had no associated illnesses (non-AC group). All 10 young patients with ACs showed ipsilateral CSDHs including a CSDH apart from an AC. All 17 patients in both the AC and non-AC groups showed headache but no paresis at admission. The pathogenesis of CSDHs associated with ACs may be different among the three types of locations. The clinical characteristics of patients with a combination of a CSDH and an AC including headache as a major symptom may be attributed to young age in the majority of patients with ACs.

    Rectus sheath hematoma (RSH) is an uncommon clinical event usually associated with trauma or coagulation disorders. It can also occur spontaneously. RSH usually runs a benign course but it can present with hypovolemic shock. When conservative management fails, surgical exploration becomes mandatory.

  12. Spontaneous spinal epidural hematoma diagnosed by CT scan

    International Nuclear Information System (INIS)

    A case of spinal epidural hematoma diagnosed by CT scan is reported. A 58-year-old man was admitted on June 18, 1984. He had had a sudden onset of severe low-back pain 7 days before admission and had developed paraparesis and numbness of the lower limbs 4 day before admission. Physical examination revealed weakness in the lower limbs, with the reflexes there decreased. The Babinski reflex and the Chaddock reflex were, however, present on both sides. Sensory disturbances were noted below L2. Urinary incontinence was present, too. Metrizamide myelography revealed an epidural mass which was located from the power part of T11 to the upper part of L2. A CT scan revealed a biconvex, relatively high-density mass in the posterior spinal canal. On the day of admission, a laminectomy was performed from T11 to L1, and the epidural hematoma was evacuated. The postoperative course was uneventful. Spinal epidural hematoma is uncommon. A CT scan can be used for an early diagnosis of this lesion. According to the review of the CT findings in 15 reported cases, including our case, CT reveals a smoothly marginated biconvex homogeneous density mass. The density of the hematoma decreases with the time. An acute type (within 3 days) is high-density, while a chronic type has a relatively high or isodensity. The acute type is easily differentiated from other epidural masses, such as a herniated disc, an epidural abscess, and an epidural tumor. On the other hand, the diagnosis of the chronic type is not always easy. (author)

    Full Text Available Reports of retropharyngeal hematoma have been scarce in the anesthesiology literature. We report a patient whose trachea was difficult to intubate due to retropharyngeal hematoma after stabbing to the neck. A woman with a knife injury to the common carotid artery required emergency carotid arterioplasty. When tracheal intubation was attempted, marked swelling of the posterior pharyngeal wall made the vocal cords impossible to visualize. Preoperative computed tomography showed a retropharyngeal hematoma. The patient required mechanical ventilation for 2 days.

    Spontaneous dissection of the internal carotid artery (CAD) is an increasingly recognized cause for stroke especially in young and middle-aged patients. We hypothesized that non-enhanced cranial computed tomography (NECCT) can visualize the subpetrous carotid wall hematoma and thus enable identification of patients with CAD. We retrospectively reviewed patients with confirmed CAD (n=21) and a control group with ischemic symptoms but without CAD (n=42) who received NECCT at admission. Two independent neuroradiologists rated the presence and shape of SPH, density and diameter of the subpetrous internal carotid artery. Additionally, we correlated the shape of the subpetrous carotid wall hematoma with the grade of stenosis on subsequent angiographic imaging. The subpetrous carotid wall hematoma was present in 14 of 21 patients (Cohen's k = 0.67). Mean diameter was 6.95 ± 1.05 mm in dissected vessels and 5.71 ± 1.52 mm in the contralateral vessel (p<0.05). Mean difference in vessel density was 15.05 ± 8.01 HU (p<0.01). Median grade of stenosis was significantly higher in patients with a full moon- shaped (n=11) than crescent-shaped (n=3) subpetrous carotid wall hematoma (21% vs. 80%, p<0.05). Two-thirds of patients with CAD were correctly identified on NECCT. The extracranial carotid artery should be evaluated in patients with symptoms of cerebral ischemia.

  16. Percutaneous drainage of a postoperative intraspinal hematoma using a Tuohy needle

    International Nuclear Information System (INIS)

    A 78-year-old man developed a large subdural hematoma extending from T12 to L3 levels following L3 laminectomy and L3-5 posterior spinal fusion. He had associated neurological signs and symptoms. MR imaging showed typical signal characteristics of a subacute intraspinal subdural hematoma. Percutaneous drainage was successfully performed under CT guidance by inserting a Tuohy needle through the L3 laminectomy defect. The catheter packaged with the Tuohy needle was inserted cranially into the hematoma and 30 ml of blood was aspirated. Follow-up MR imaging confirmed resolution of the hematoma and the patient made a rapid recovery. (orig.)

  17. Clinical application of CT-controlled stereotactic aspiration for intracerebral hematoma

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical application of CT-controlled stereotactic aspiration for intracerebral hematoma. Methods: CT-guided stereotactic system was installed on the CT bed, and checked against a standard of the coordinate. According to controlled CT scan, the target can be adjusted at any time in the operation. 860 patients with cerebral hematoma underwent CT-controlled stereotactic aspiration. Of the 860 cases, basal ganglion hematoma was present in 408, thalamus and posterior limb of internal capsule hematoma in 136, cerebral lobe hematoma in 261, cerebellar hematoma in 5, ventricular hemorrhage in 10, midbrain and pons hemorrhage in 37, and medulla hemorrhage in 3. Results: Easy drainage of hematoma by aspiration was achieved in 586 cases, stickiness of hematoma with clearing away more than 50% was performed in 202 and less than 50% in 68. The operation duration ranged from 25 to 120 minutes (average 45 minutes). 693 cases survived and 167 cases died. According to the evaluation by active day life (ADL) after 3 months in survivors, ADL 1-2, ADL 3, ADL 4 and ADL 5 results were achieved in 378 cases, 166 cases, 107 cases, and 28 cases, respectively. In addition, 14 cases were lost beyond recall. Conclusion: CT-controlled stereotactic aspiration for intracerebral hematoma is a handy, less invasive, and safe procedure with high accuracy and curative effect, it is worth while popularizing the procedure

    An uncommon case of chronic nontraumatic spinal epidural hematoma of the lumbar spine in a 75-year-old woman is reported. The patient presented with a 7-month history of low back pain and bilateral sciatica. Magnetic resonance imaging enabled a correct preoperative diagnosis revealing a nodular, well-circumscribed epidural mass with peripheral enhancement and signal intensities consistent with chronic hematoma, which extended from L2 to L3. Laminectomy of L2-L3 was performed and the hematoma was totally resected. Histological examination of the surgical specimen demonstrated a chronic encapsulated hematoma. No evidence of vascular malformation was found. The patient recovered fully after surgical treatment. (orig.)

    1955-12-01

    Full Text Available Êste trabalho tem por fim demonstrar o valor da fase venosa em incidência sagital no diagnóstico angiográfico dos hematomas subdurais. Êle é baseado em 8 casos verificados cirürgicamente, dois dos quais com hematoma bilateral, compreendendo um total de 10 hematomas subdurals demonstrados pela angiog [...] rafia cerebral. Em 9 exemplares a elipse avascular que caracteriza essa entidade nosológica só apareceu na fase venosa; sòmente em um caso êsse sinal patognomônico foi claramente revelado na fase arterial em incidência ântero-posterior. O arteriograma mostra, apenas, às mais das vêzes, deslocamento da artéria cerebral anterior e seus ramos para o lado oposto àquele em que se encontra o hematoma, como acontece nos casos de lesões expansivas em geral. Menos freqüentemente os principais troncos arteriais do encéfalo não sofrem modificações no seu trajeto, apesar do espaço intracraniano ocupado pelos hematomas. A existência de hematoma subdural no interior de um hemicrânio sem desvio da artéria cerebral anterior, embora não implique necessàriamente na existência de outra coleção sangüínea do lado oposto, é altamente sugestiva dessa dupla lesão. A exploração bilateral nesses casos é, portanto, obrigatória. Dos três casos desta série em que a angiografia em um dos lados revelou a elipse avascular característica e artéria cerebral anterior com trajeto normal, a angiografia do lado oposto resultou positiva em dois dêles e negativa em um. Pôsto que alguns Serviços especializados não sejam dotados de equipamento para angiografia em séries, o autor recomenda o flebograma em incidência sagital como tempo obrigatório, mesmo que para tanto seja necessária nova injeção de contraste. Abstract in english This repport aims to demonstrate the value of the venous phase, in sagittal incidence, for the angiographic diagnosis of subdural hematoma. It is based on eight such cases, all of them with surgical confirmation. Six of the patients had unilateral hematomas and the remaining two had bilateral blood [...] collections. Ten subdural hematomas were, then, diagnosed by means of cerebral angiography. In only one instance the elliptical non vascularized area which constitutes the pathognomonic sign of the above referred nosological entity could be seen, under frontal projection, right in the arterial phase. In the other cases the specific diagnosis of subdural hematoma would not be achieved if the venous phase had not been taken in account. The arterial displacement seen in most cases of subdural hematoma gives no help for specific diagnosis; such a displacement may occur in any case of space-occupying lesion. Besides, existence of subdural hematomas with no arterial dislocation, is a known condition, mainly in that cases of bilateral subdural blood collections. On the other hand a single, unilateral hematoma with no shifting of the anterior cerebral artery to the opposite side is also suitable. In the last three cases of this series, there was no significant displacement of the anterior cerebral artery; the venous phase, in antero-posterior incidence, and further surgical exploration, showed the hematomas to be bilateral in two; in the third of these cases the anterior cerebral artery had a normal course, in spite of the space taken by a single hematoma. Thus, if the venous phase shows the characteristic picture of subdural hematoma - avascular area - with no displacement in the arterial phase, it does not mean necessarily that the hematoma is bilateral. Nevertheless angiography on opposite side must always be done. Since in angiographic diagnosis of subdural hematoma the accuracy of the venous phase, in sagittal projection seems to be proven, we think that the above mentioned step of the examination has to be done even if, in order to achieve it, a new injection of contrast may be required.

    Calcified chronic subdural hematoma is a rare condition, representing 0.4-2.6% of all chronic subdural hematomas. It is often difficult to remove the hematoma without damaging the brain, owing to the adhesion between hematoma capsule and brain. Therefore, surgical intervention in managing calcified chronic subdural hematoma cases is still considered controversial. We report a case of calcified chronic subdural hematoma, which was successfully performed under microscopic guidance. A 72-year-old man complained of progressive left hemiparesis of 6-month duration. A CT scan revealed a calcified chronic subdural hematoma, 10 cm long and 4.5 cm thick, in the right convexity. On MRI, T2-weighted images showed a thin layer of cerebrospinal fluid intensity between the hematoma capsule and brain. There was no brain edema adjacent to the chronic subdural hematoma. Based on these MRI observations, we believed that adhesion between the hematoma capsule and brain would be mild. We then planned and succeeded in total removal of the calcified chronic subdural hematoma mass under microscopic guidance. The left hemiparesis disappeared after surgery. The patient was discharged without any neurological deficit. While considering surgical management in calcified chronic subdural hematoma cases, it should be important to evaluate adhesion between the hematoma capsule and brain with MRI. PMID:25087759

Nerve function recovery was assessed using the Bain-Mackinnon-Hunter Sciatic Function Index (SFI. At the end of the study, the animals were sacrificed and a specimen of the sciatic nerve at compression midpoint was removed for morphometric analysis. Group A displayed an initial SFI of -28.43, with full functional recovery on the fifth day. Immediate drainage of the hematoma by longitudinal epineurotomy (group B promoted recovery of normal sciatic function on the first day (SFI -14.42. Addressing the hematoma via interfascicular neurolysis resulted in an initial SFI of -23.69 and recovery of normal sciatic function on the third day. The morphometric variables indicated an improvement of ischemic parameters following both types of surgical intervention.

    Patients with acute intracranial hematomas often require surgical drainage within the first four hours after traumatic brain injury (TBI) to avoid death or severe neurologic disability. CT and MRI permit rapid, noninvasive diagnosis of hematomas, but can be used only at a major health-care facility. At present, there is no device for noninvasive detection and characterization of hematomas in pre-hospital settings. We proposed to use an optoacoustic technique for rapid, noninvasive diagnosis and monitoring of hematomas, including intracranial hematomas. Unlike bulky CT and MR equipment, an optoacoustic system can be small and easily transported in an emergency vehicle. In this study we used a specially-designed blast device to inflict TBI in rats. A near-infrared OPO-based optoacoustic system developed for hematoma diagnosis and for blood oxygenation monitoring in the superior sagittal sinus (SSS) in small animals was used in the study. Optoacoustic signals recorded simultaneously from the SSS and hematomas allowed for measurements of their oxygenations. The presence of hematomas was confirmed after the experiment in gross pictures of the exposed brains. After blast the hematoma signal and oxygenation increased, while SSS oxygenation decreased due to the blastinduced TBI. The increase of the oxygenation in fresh hematomas may be explained by the leakage of blood from arteries which have higher blood pressure compared to that of veins. These results indicate that the optoacoustic technique can be used for early diagnosis of hematomas and may provide important information for improving outcomes in patients with TBI or stroke (both hemorrhagic and ischemic).

CT scan was performed to diagnose the bleeding, MRI and at least two digital subtraction angiography (DSA) were the methods of diagnosis. Results. Thirty-nine patients presented ICH. Twenty presented AVM, five aneurysm, one tumor, three dural sinus thrombosis. In 4 females and 6 males (ages 2 months to12 years) no etiology could be found. Six patients had headache, four sensory loss and two seizures. The cerebellar hemisphere was involved in two patients, basal ganglia in two, thalamus in one and five were subcortical located. Six presented intraventricular haemorrhage, and needed external ventricular drainage. Six patients underwent clot removal because of mass effect. All patients survived. Four remained with hemiparesia. Coclusion. In 25% of patients with ICH no etiology could be found in spite of being fully checked. The majority of them were between 6 and 12 years old. There were no children over 12 years. There were no deaths in this serie; therefore early surgery due to increased ICP seems to have a favorable outcome.

    We aimed to evaluate the functional outcome and risk factors of recurrence in patients operated on for a chronic subdural hematoma (CSH), and discuss systematic early postoperative CT scans. CSH is a very common disease in neurosurgical practice, especially in elderly patients who are treated with anticoagulation. The challenge is to rapidly restore the independence of these patients. We retrospectively analyzed data from 164 consecutive surgical procedures performed on 140 CSH patients, including recurrent surgery, at our institution from June 2011 to June 2012. Pre- and postoperative CT scans, and medical records, were systematically reviewed using the institutional computing database. A poor functional outcome was defined by a modified Rankin scale (mRS) score>2 at 3months. Among the 140 patients (mean age 76years; 64% men), a single burr hole craniostomy was performed in 122 patients, and a craniotomy in 18. A poor functional outcome was recorded in 39 patients (28%; 95% confidence interval [CI] 20-35%). In multivariate analyses, an increased risk of poor functional outcome was associated with age >75years (odds ratio [OR] 5.88; 95% CI 1.96-17.63), residual hematoma thickness >14mm (OR 3.79; 95% CI 1.47-9.77), and GCSCT scan (OR 5.61; 95% CI 1.52-20.66). Three months after surgical treatment, more than one quarter of the CSH patients had a mRS?3. The loss of independence was associated with older age, initial GCS<15, and residual hematoma thickness postoperatively. Anticoagulant therapy and persistence of postoperative mass effect heightened the risk of recurrence. PMID:26260114

    The authors describe a case of 70-year-old woman, who developed a subphrenic abscess after D2 gastrectomy. The abscess looked like an acute subcapsular splenic hematoma on computed tomography images. Therefore the patient was reoperated. It turned out during the operation that there was a subphrenic pus collection, while the spleen had been intact. The reason for this complication was unoesophagal fistula. The case report shows limitations of CT images interpretation and a failure that can result from fixed bearing radiological criteria. (author)

    Full Text Available Drepanocytic anemia is an uncommon hereditary disease in Chile. The heterozygous state of drepanocytic anemia or "sickle trait" has a frequency of 8% among Afro-Americans. A small number of patients carrying hemoglobin S are homozygous, with clinical manifestations of hemolytic anemia and thrombotic disease. Sickle trait is usually asymptomatic. We report a 59-year-old male who presented an acute abdominal pain and dyspnea while staying at high altitude. Six days later, an angio CAT scan showed the presence of a subcapsular splenic hematoma that was managed conservatively. Sickle cell induction with sodium metabisulphite was positive. Hemoglobin electrophoresis confirmed the sickle trait.

Sometimes their imaging features can be non-specific, so differentiation from other aggressive lesions like hepatoblastoma can be difficult, especially if there is a concurrent high {alpha}-fetoprotein level. We report a case of intrahepatic hematoma with a rising {alpha}-fetoprotein level. (orig.)

    Full Text Available Spinal subdural hematoma (SDH following a cranial surgery is extremely rare. We described a 26-year-old patient who developed an SDH at L3-S1 level after the excision of intraventricular meningioma. He was surgically treated with an excellent outcome. It is postulated that the SDH resulted from downward migration of intracranial hematoma.

  1. CT findings and clinical analysis of subcortical hematomas in elderly patients

    International Nuclear Information System (INIS)

    Ten elderly patients (73-87 years, 78.4 years on the average) with subcortical hematomas were divided into two groups according to the shape of the hematoma on a CT scan: a lobulated group (6 patients) and a global group (4 patients). The lobulated group had a history of hypertension in one patient. The hematomas extended widely around the parietal lobe and were accompanied by perifocal edema, brain shifts and subarachnoid hemorrhages, deep consciousness disturbances, and poor prognosis of life and function. Amyloid depositions in the arteries around the hematomas were confirmed histologically in one patient. The global group had a history of hypertension in two patients. The hematomas were localized in the parietal, temporal, or occipital lobe without perifocal edema, brain shift and subarachnoid hemorrhages, and accompanied by mild consciousness disturbances. The life prognosis was good, but the functional prognosis was poor, with a subsequent development of dementia. A lobulated subcortical hematoma is thought to be due to amyloid angiopathy, while a global subcortical hematoma is thought to be due to hypertension. A surgical evacuation is seldom indicated for either type of subcortical hematoma in elderly patients. (author)

    An 81-year-old man, who experienced upper abdominal pain after shoveling snow, was admitted to a local hospital where a computed tomography (CT) showed a cystic lesion adjoining the pancreas. He was transferred to our department for detailed investigations and treatment. On ultrasonography, a tumor of the caudate lobe of the liver, with which the cystic lesion was continuous, was seen. The tumor of the caudate lobe of the liver was enhanced in the early phase of the CT but was washed out in the delayed phase. Subsequently, T(1)-weighted and T(2)-weighted magnetic resonance imaging (MRI) images showed a low intensity and a high intensity, respectively. Because the cystic lesion was continuous with the tumor of the caudate lobe of the liver, its CT value was higher than that of water, and both the T(1)-weighted and T(2)-weighted MRI images showed a high intensity, which was attributed to a hematoma. Examination of the image suggested that rupture of a hepatocellular carcinoma (HCC) might have caused intracavitary hemorrhage. After the HCC was treated by transcatheter arterial embolization therapy, the patient was discharged. Subsequently, tumor enlargement was confirmed, and surgical removal of the tumor was conducted at the hospital where the patient had originally presented. On histology, moderately differentiated HCC was diagnosed, but the cyst-like lesion was confirmed to be a hepatic subcapsular hematoma extending into the bursa omentalis. Although ruptured HCC often causes intraperitoneal bleeding, this rare case showed a cyst-like imaging finding in the form of a subcapsular hematoma within the bursa omentalis. PMID:19796037

    Full Text Available Sublingual hematoma secondary to anticoagulation is a rare fatal condition. Hemorrhagic complications of warfarin are well-known. This particular case is unique because the patient was on warfarin for the past 2 years but did not develop the sublingual hematoma. However, a trauma by an attrited sharp cusp triggered the episode of the sublingual hematoma in this patient. Being a medical emergency, patient was promptly hospitalized in cardiac care unit and managed by medical team. The patient was transfused with 2 units of fresh frozen plasma and warfarin was temporarily stopped for 4 days. Alternate day regimen of warfarin was started after 4 days, and international normalized ratio dropped to 3. In dental management, enameloplasty of the mandibular first molar tooth was done to prevent trauma and ulcer development in the floor of the mouth. The hematoma resolved, and no new hematoma formation was observed for a period of 6 months.

    Pre-treatment with antiplatelet agents is described to be a risk factor for mortality after spontaneous intracerebral hemorrhage (ICH). However, the impact of antithrombotic agents on mortality in patients who undergo hematoma evacuation compared to conservatively treated patients with ICH remains controversial. This analysis is based on a prospective registry for quality assurance in stroke care in the State of Hesse, Germany. Patients' data were collected between January 2008 and December 2012. Only patients with the diagnosis of spontaneous ICH were included (International Classification of Diseases 10th Revision codes I61.0-I61.9). Predictors of in-hospital mortality were determined by univariate analysis. Predictors with P<0.1 were included in a binary logistic regression model. The binary logistic regression model was adjusted for age, initial Glasgow Coma Score (GCS), the presence of intraventricular hemorrhage (IVH), and pre-ICH disability prior to ictus. In 8,421 patients with spontaneous ICH, pre-treatment with oral anticoagulants or antiplatelet agents was documented in 16.3% and 25.1%, respectively. Overall in-hospital mortality was 23.2%. In-hospital mortality was decreased in operatively treated patients compared to conservatively treated patients (11.6% versus 24.0%; P<0.001). Patients with antiplatelet pre-treatment had a significantly higher risk of death during the hospital stay after hematoma evacuation (odds ratio [OR]: 2.5; 95% confidence interval [CI]: 1.24-4.97; P=0.010) compared to patients without antiplatelet pre-treatment treatment (OR: 0.9; 95% CI: 0.79-1.09; P=0.376). In conclusion a higher rate of in-hospital mortality after pre-treatment with antiplatelet agents in combination with hematoma evacuation after spontaneous ICH was observed in the presented cohort.

  9. MRI study for CT-guided stereotactic aspiration of intracerebral hematoma

    International Nuclear Information System (INIS)

    Twenty-five patients with acute hypertensive intracerebral hematomas, diagnosed by computed tomography (CT), underwent CT-guided stereotactic aspiration. Magnetic resonance (MR) images were obtained immediately before aspiration, using T1-weighted (TR=500 msec, TE=15 msec) and T2-weighted (TR=2500 msec, TE=120 msec) sequences and a 0.5 Tesla MR system. On the basis of the MR images the hematomas were divided into peripheral, central, and core segments. The signal intensities were divided into seven grades based on the comparison with white matter. The sequential changes in each segment on the MR images were evaluated, and the ratio of hematoma removal vs. size of residual hematoma was assessed by preoperative MR imaging and pre-and post-operative CT. The hematomas were located in the putamen in 13 cases, the thalamus in 8, combined in 2, and subcortex in 2. The hematomas, targeted in their centers, were evacuated by the aspiration procedure alone, 1 to 12 days after onset (day 0=day of onset). The results were as follows : 1) The proportion of hematomas removed was high after day 4. 2) Sequential T1-weighted images showed that the peripheral segments gradually increased in signal intensity, appearing as high-intensity rings that gradually filled and could be easily aspirated. 3) In those cases in which sequential T2-weighted images showed the central segments gradually increasing in signal intensity, the hematomas were easily aspirated if the signal was either iso-intense or hyper-intense. 4) Several hematomas had a core that appeared as a high intensity signal on T1-weighted images and as a low intensity signal on T2-weighted images; these hematomas could not be aspirated.

    Full Text Available Paciente masculino de 65 años de edad, con antecedentes de habérsele colocado stent coronario y tratamiento antiagregante plaquetario con Aspirina® y Clopidogrel®. A los 21 días comenzó a presentar dolor en el flanco y la fosa ilíaca derechos, náuseas y vómitos. En el examen físico inicial se detectó dolor y aumento de volumen en las zonas referidas y los signos vitales normales. El ultrasonido abdominal reveló colección perirrenal derecha bien delimitada y riñones de tamaño y ecoestructura normal. La tomografía axial computarizada evidenció la presencia de una imagen renal subcapsular derecha, con densidades de líquido, con compresión extrínseca de un riñón estructuralmente normal. Al día siguiente del ingreso comenzó a presentar fiebre de 38 ºC. Se suspendió el tratamiento antiagregante plaquetario y a los 7 días se realizó lumbotomía y drenaje del hematoma; se obtuvo alrededor de 400 mL de sangre carmelitosa. El paciente evolucionó satisfactoriamente. Se concluye que el hematoma renal subcapsular espontáneo es una complicación inusual del uso de antiagregantes plaquetarios que necesita manejo multidisciplinario. La tomografía axial computarizada es indispensable para el diagnóstico imagenológico de certeza. La compresión renal por su gran tamaño, así como el dolor y la aparición de fiebre, justifican su drenaje quirúrgico.

    Intracranial subdural hematoma (SDH) occurred in a 58-year-old female after laparoscopy-assisted distal gastrectomy under general and thoracic epidural anesthesia. On postoperative day 2, she complained of headache in sitting position, but there were no remarkable neurological defect and nausea. On postoperative day 5, her headache subsided and she could walk by herself. But on postoperative day 10, she felt heavy-headed again, and complained sensory abnormality of her right leg. Magnetic resonance imaging of the head showed small acute subdural hematoma in bilateral parietal regions with no mass effect. She was managed conservatively with bed rest and intravenous fluids. Her condition improved and was discharged on postoperative day 17 without subsequent complications. SDH after epidural anesthesia is rare, but diagnosis in early stage has a decisive influence on its prognosis. It is crucial to exclude the possibility of SDH and observe closely if the patient complains of severe headache or another unexplained symptom only with postdural puncture headache. PMID:23544334

  12. Process of evolution to chronic subdural hematoma, (1)

    International Nuclear Information System (INIS)

    The process of evolution to chronic subdural hematoma (CSH) was discussed on the basis of MRI and CT findings. The materials were 22 sides of 15 cases in which CSH had been diagnosed by means of MRI, CT, and/or surgery. These cases were followed by CT with/without MRI after the initial head injury. Various findings were shown in the subdural space, such as subdural hygroma (40%), acute subdural hematoma (25%), normal state (20%), and traumatic subarachnoid hemorrhage (15%). Regardless of the conditions of the subdural space after the head injury, however, CSH was finally present in all cases after the formation of subdural hygroma and its enlargement. The duration of the formation of hygroma after head injury ranged from 0 to 12 days (mean: 2.7 days), and its final confirmation ranged from 11 to 61 days (mean: 33.4 days). The period from the final confirmation of hygroma to the first recognition of CSH was between 8 and 36 days (mean: 17.7 days), while the period from head injury to the formation of CSH was between 27 and 75 days (mean: 51.1 days). The process of evolution to CSH may be thought to be as follows: A normal subdural space changes into a subdural hygroma by the tearing of the arachnoid membrane due to head injury. Capsule formation follows the process lasting for more than three weeks. CSH develops in consequence of bleeding from the outer membrane. (author)

  13. A missed injury leading to delayed diagnosis and postoperative infection of an unstable thoracic spine fracture - case report of a potentially preventable complication

    Directory of Open Access Journals (Sweden)

    Stahel Philip F

    2011-10-01

    Full Text Available Abstract Background Patients suffering from polytrauma often present with altered mental status and have varying levels of examinability. This makes evaluation difficult. Physicians are often required to rely on advanced imaging techniques to make prompt and accurate diagnoses. Occasionally, injury detection on advanced imaging studies can be challenging given the subtle findings associated with certain conditions, such as diffuse idiopathic skeletal hyperostosis (DISH. Delayed or missed diagnoses in the setting of spinal fracture can lead to catastrophic neurological injury. Case presentation A man struck by a motor vehicle suffered multiple traumatic injuries including numerous rib fractures, a mechanically unstable pelvic fracture, and also had suspicion for an aortic injury. Unfortunately, the upper thoracic segment (T1-5 was only visualized with axial images based on the electronic data. Several days later, a contrast CT scan obtained to check the status of suspected aortic injury revealed T3-T4 subluxation indicative of an unstable extension-type fracture in the setting of DISH. Due to the missed injury and delay in diagnosis, surgery was not performed until eight days after the injury. At surgery, the patient was found to have left T3-T4 facet joint infection as well as infected hematoma surrounding a left T4 transverse process fracture and a traumatic T4 costo-transverse joint fracture-subluxation. Despite presence of infection, an instrumented posterior spinal fusion from T1-T6 was performed and the patient recovered well after antibiotic treatment. Conclusion A T3-T4 unstable DISH extension-type fracture was initially missed in a polytrauma patient due to inadequate imaging acquisition, which caused a delay in treatment and bacterial seeding of fracture hematoma. Complete imaging is especially needed in obtunded patients that cannot be thoroughly examined.

  14. Delayed neutrons

    International Nuclear Information System (INIS)

    When nuclear weapons explode, they produce neutrons in two groups characterized by their time of emission. Prompt neutrons emerge from fissioning atoms for a few microseconds following initiation of the explosion. Delayed neutrons emerge from fission products for several tens of seconds following the fissions. Because of this time difference, the two groups are produced in quite different materials. The prompt neutrons are produced within the still intact bomb; the delayed neutrons are produced within the fireball. The mass of the air in the fireball far exceeds the mass of the bomb material that is dispersed within it; thus the delayed neutrons are essentially produced in air. The difference in the materials in which the neutrons are produced requires different approaches in the calculation of the numbers that reach the survivors. Nuclear bombs developed in recent years have been lighter than those dropped on Hiroshima and Nagasaki. Because of the smaller mass, relatively more prompt neutrons escape and they escape with higher energies. The number emerging is two orders of magnitude more than the number of delayed neutrons released. As a consequence, the delayed neutrons had been considered unimportant and no methods for calculating their penetration through the atmosphere had been developed. Because of the greater mass of the Hiroshima and Nagasaki bombs, the delayed neutrons could not be assumed to be negligible and the present work was initiated. The delayed neutron program had three parts: 1) development of a computation method, 2) verification and validation of the methods, and 3) calculation of the energy and angle-differential fluences for the Hiroshima and Nagasaki bombs and their incorporation into the DS86 dosimetry program

    2015-01-01

    A 10-year-old girl presented with exercise intolerance, learning difficulty, and muscle weakness in a limb girdle distribution. She had delayed achievement of motor milestones and difficulties with social interaction at pre-school age. Muscle biopsy showed no myopathic or dystrophic features, but 90% COX negative fibres and ragged blue fibres. Respiratory chain enzyme analysis in muscle showed a combined deficiency and mitochondrial DNA sequencing revealed the presence of an m.4450G>A mutation in the MT-TM gene encoding the tRNA for methionine. The mutation was only detected in mtDNA extracted from muscle and skin fibroblast, and could not be found in other tissues or in the mother. This is the second patient reported in the literature with a mitochondrial myopathy due to a mt-tRNA(Met) mutation. The first patient, a 30-year-old woman, presented with exercise intolerance, limb girdle muscle weakness, lactic acidosis, learning difficulty, and growth retardation in early childhood. Thus, the two patients exhibit strikingly overlapping phenotypes.

    Delay is one of the issues most frequently encountered in today’s construction industry; it causes significant economic damage to all parties involved. Construction contracts, standard and bespoke, almost invariably consider delay from a perspective of single liability. If the event causing the delay is contractually defined as a contractor's risk, the contractor is liable to pay liquidated damages to the employer; if it is not, the contractor can under certain circumstances claim an extension of time and in some cases also economic compensation from the employer. The situation where a given period of delay can potentially be attributed to several events falling within both parties' spheres of responsibility, commonly termed concurrent delay, is rarely regulated in construction contracts in spite of its common occurrence. This book analyses both the theoretical foundations and the practical solutions to the issue of concurrent delay in a comparative perspective between common and civil law systems, with an emphasis on Danish and English law.

Foi submetido a terapia trombolítica com estreptoquinase por via venosa, no membro superior contra-lateral, na dose de 250.000UI em 15min, seguida de 100.000UI/h durante cinco dias, com total recanalização do trombo e redução do edema. Após 24h do término da trombólise, apresentou disfagia a líquidos e o esofagograma mostrou extensa compressão extrínseca do esôfago, por provável hematoma retroesofágico. Necessitou de nutrição enteral durante três meses, quando ocorreu normalização da deglutição, reabsorção do hematoma retroesofágico e passagem adequada do contraste pelo esôfago. No seguimento evolutivo não apresentou seqüelas da trombose venosa profunda, não tem disfagia e permaneceu em uso profilático de meias elásticas e heparina de baixo peso molecular. Abstract in english We report the case of a 72 year-old man with advanced, stage IV, prostate cancer who underwent osteosynthesis of the cervical spine for nerve root decompression due to metastasis which was causing severe pain in his right upper limb. After three months in the hospital, he developed occlusive thrombo [...] sis of the right axillosubclavian vein as a complication of prolonged catheterization of the right subclavian vein for treatment of septicemia secondary to a hospital acquired pneumonia. The patient received thrombolytic therapy with IV streptokinase in the contralateral arm in the following dosage: 250,000 units in 15 minutes followed by 100,000 units per hour during five days. This led to total recanalization of the thrombus, with significant reduction of the arm edema. Twenty-four hours after the end of the thrombolytic therapy, the patient started to complain of dysfagia to solids and liquids and a contrasted esophagogram revealed extensive extrinsic compression of the esophagus due to a probable retroesophageal hematoma. The patient required enteral nutrition via nasoenteral tube during three months after which swallowing returned to normal and a repeat upper GI series confirmed that the hematoma had been reabsorbed, with normal passage of contrast through the esophagus. On late follow-up, the patient did not show evidence of any sequelae of deep venous thrombosis nor any residual dysfagia and is currently in use of elastic stockings and low molecular weight heparin.

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

  7. Importance of computerized tomography for surgical treatment of intracranial hematomas

    International Nuclear Information System (INIS)

    The improved treatment by using computerized tomography (CT) located operating theater and intensive care unit is reported in comparison of 3,382 patients with severe head injuries. By preoperative use of CT the frequency of diagnosed hermatomas was about the same (29.5% before CT; 27.0% with CT) but the preoperative diagnosed multiple hematomas were much more frequent (14.0% resp. 27.0%). The most important advantage however is the saving of time by CT in this localisation by which the chance of survival has increased from 54% to 69%. Without any doubt everywhere in neurotraumatology the CT should be situated as near as possible to the intensive care unit and to the operating theater and should be available 24 hours a day.

    2014-05-01

    Extradural hematoma (EDH) after ventriculoperitoneal (VP) shunt procedure is a rare, dangerous but easily avoidable and manageable complication. It is more common in children and young adults presumably due to relatively lax adhesion of dura to calvarium. We report a case of an 18-year-old male with acqueductal stenosis who underwent VP shunt procedure. Three months later, a computed tomography (CT) scan was done for the complaints of intractable headache and altered sensorium which showed chronic calcified EDH near shunt site. The ventricular catheter was in position and the ventricles were decompressed. After surgical decompression of EDH his symptoms improved. We discuss the factors leading to formation of EDH, with stress on proper technique to prevent or minimize such an avoidable complication. PMID:25250078

    A woman, aged 84 years, presented to our emergency department with posteriorly radiating chest pain that began following dinner. She reported no change in bowel habits, hematochezia, or melena. She had previous peptic ulcer disease and a long-standing history of gastroesophageal reflux disease. Her medications included acetylsalicylic acid and rabeprazole. Electrocardiogram and troponin analyses were negative for ischemic heart disease. The emergency physician suspected an aortic dissection, and computed tomography (CT) chest and abdomen scans were performed with and without IV and oral contrast. The aorta was normal and the noncontrast images demonstrated a hyperdense mass (not shown) that did not enhance consistent with a large intramural hematoma extending from the upper esophagus (level of T2 vertebral body) to the fundus of the stomach (Figures 1A and B).

  10. Delayed puberty.

    2012-01-01

    Since puberty is a long ongoing developmental process with significant individual and population differences in timing, the definition of delayed puberty for a given individual needs to rest on simple, though arbitrary criteria based on epidemiological data. Although several genes involved in the hypothalamic-pituitary-gonadal maturation cascade have been characterized recently from familial or sporadic cases of primitive isolated hypogonadotropic hypogonadism, many genes regulating puberty onset remain undetermined. In case of delayed puberty and/or primary amenorrhea, a complete clinical examination including a detailed past history will evaluate the development of secondary sex characteristics, verify the association with a growth delay and look for specific indicative features pertaining to the etiological diagnosis. This clinical check-up completed if necessary with biological, ultrasonographic, radiological and genetic investigations will try to determine which girls will have a permanent sexual infantilism of gonadal, hypophyseal or hypothalamic origin, which girls will undergo spontaneous but delayed puberty and which girls have primary amenorrhea with developed secondary sex characteristics. Therapeutic attitude will have to integrate etiological factors, statural prognosis, bone mass preservation and psychological factors. PMID:22846526

    To bring attention to the MR imaging appearance of epidural hematoma (EDH) in the lumbar spine as a small mass often associated with disk herniation or an acute event. This paper will show our experience with this entity and describe criteria for its MR imaging appearance. Design and patients. Thirteen cases of prospectively diagnosed EDH of the lumbar spine were compared with 12 cases of prospectively diagnosed prominent epidural extrusion. Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk extrusions. (orig.)

    Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disorder characterised by abnormal ciliary motion and impaired mucociliary clearance, leading to recurrent respiratory infections, sinusitis, otitis media and male infertility. Some patients also have laterality defects. We recently reported the identification of three disease-causing PCD genes in the Irish Traveller population; RSPH4A, DYX1C1 and CCNO. We have since assessed an additional Irish Traveller family with a complex phenotype involving PCD who did not have any of the previously identified PCD mutations.

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

    The authors present a case of intramural hematoma of the small intestines during anticoagulant treatment. With reference to this case, they study the frequency, etiopathogenesis and anatomy of this hematoma and particularly look at the radiological manifestations. In this respect they distinguish three stages in the evolution. The first, when the straight X-ray of the abdomen and barium followthrough demonstrate an axial stenosis of the small intestines with dilation of the proximal loops; the second (between the 7th and 20th days) when the loop affected by the hematoma takes on a characteristic "palissade" or "spring" -like sausage appearance; finally the third (after the 3rd week), when only thickening of the haustrations persists with progressive return to normal. The radiological diagnosis is discussed, not only with intramural hematomas of the small intestines of other etiologies (traumatic, during pancreatitis, during disorders in hemostatis), but also with conditions giving rise to similar radiological pictures: malabsorption, inflammatory conditions, etc. PMID:300805

    An arachnoid cyst found to have a communication to an associated subdural hematoma was demonstrated with the Tc-99m DTPA brain scintigraphy. Although arachnoid cysts are known to be silent, when a patient with an arachnoid cyst develops signs of increased intracranial pressure or neurological deficits, the presence of a complication, including subdural hematoma, intracystic hemorrhage or subdural hygroma, is highly suspected. In the present case, the patient with an arachnoid cyst had a subdural hematoma following minor head injury. Tc-99m DTPA brain scintigraphy showed abnormal accumulation of the tracer not only in the hematoma but in the arachnoid cyst. This observation suggested communication of the two lesions, which was confirmed at surgery.

    Twenty-three cases of chronic subdural hematoma were observed soon after head injury for the relationship between its CT findings and clinical symptoms. It has been found that the chronic subdural hematoma is a slowly growing and expanding intracranial disease that starts in an early period of head injury. Chronic subdural hematoma did not present any signs or symptoms initially, except for the gradual occurrence of headache, but finally it presented signs of intracranial hypertension and focal signs. Chronic subdural hematoma in the hygroma-like period did not show any signs and symptoms. In the capsulated period, when changes in CT density suggested intracapsular hemorrhage, a heavy sensation of the head was noted. It was recognized as an abnormal feeling or a full sensation of the head. When the bleeding continued in the cavity, headache became continuous and focal signs gradually appeared.

    The epileptic encephalopathies are a clinically and aetiologically heterogeneous subgroup of epilepsy syndromes. Most epileptic encephalopathies have a genetic cause and patients are often found to carry a heterozygous de novo mutation in one of the genes associated with the disease entity. Occasionally recessive mutations are identified: a recent publication described a distinct neonatal epileptic encephalopathy (MIM 615905) caused by autosomal recessive mutations in the SLC13A5 gene. Here, we report eight additional patients belonging to four different families with autosomal recessive mutations in SLC13A5. SLC13A5 encodes a high affinity sodium-dependent citrate transporter, which is expressed in the brain. Neurons are considered incapable of de novo synthesis of tricarboxylic acid cycle intermediates; therefore they rely on the uptake of intermediates, such as citrate, to maintain their energy status and neurotransmitter production. The effect of all seven identified mutations (two premature stops and five amino acid substitutions) was studied in vitro, using immunocytochemistry, selective western blot and mass spectrometry. We hereby demonstrate that cells expressing mutant sodium-dependent citrate transporter have a complete loss of citrate uptake due to various cellular loss-of-function mechanisms. In addition, we provide independent proof of the involvement of autosomal recessive SLC13A5 mutations in the development of neonatal epileptic encephalopathies, and highlight teeth hypoplasia as a possible indicator for SLC13A5 screening. All three patients who tried the ketogenic diet responded well to this treatment, and future studies will allow us to ascertain whether this is a recurrent feature in this severe disorder.

    We present the case of a 78-year-old woman with a spontaneous spinal epidural hematoma that presented with sudden interscapular pain accompanied by left hemiparesis and a significant improvement 15 minutes later. Initially diagnosed as angina, the persistence of pain in dorsal cervical spine suggested the need to perform magnetic resonance imaging (MRI). The images demonstrated a lesion in the epidural spinal canal at level C3-D2 that presented a heterogeneous signal intensity, with hyperintense areas in T1-weighted sequences and hypointense areas in gradient-echo sequences, with no sign of compression myelopathy. A diagnosis of epidural hematoma was established and, given the favorable clinical course, conservative treatment was indicated. The second MRI study showed the complete resorption of the epidural hematoma. (Author) 12 refs.

    Germinal matrix hemorrhage remains the leading cause of morbidity and mortality in preterm infants in the United States with little progress made in its clinical management. Survivors are often afflicted with long-term neurological sequelae, including cerebral palsy, mental retardation, hydrocephalus, and psychiatric disorders. Blood clots disrupting normal cerebrospinal fluid circulation and absorption after germinal matrix hemorrhage are thought to be important contributors towards post-hemorrhagic hydrocephalus development. We evaluated if upregulating CD36 scavenger receptor expression in microglia and macrophages through PPAR? stimulation, which was effective in experimental adult cerebral hemorrhage models and is being evaluated clinically, will enhance hematoma resolution and ameliorate long-term brain sequelae using a neonatal rat germinal matrix hemorrhage model. PPAR? stimulation (15d-PGJ2) increased short-term PPAR? and CD36 expression levels as well as enhanced hematoma resolution, which was reversed by a PPAR? antagonist (GW9662) and CD36 siRNA. PPAR? stimulation (15d-PGJ2) also reduced long-term white matter loss and post-hemorrhagic ventricular dilation as well as improved neurofunctional outcomes, which were reversed by a PPAR? antagonist (GW9662). PPAR?-induced upregulation of CD36 in macrophages and microglia is, therefore, critical for enhancing hematoma resolution and ameliorating long-term brain sequelae. PMID:26739391

  5. CO2 Demonstration of Multiple Extravasations into a Subcapsular Hematoma of the Liver

    International Nuclear Information System (INIS)

    In a case of esophageal cancer with liver metastases, rupture of a liver metastasis resulted in subcapsular hematoma of the liver. Digital subtraction angiography with carbon dioxide showed multiple extravasations at the surface of the liver suggesting multiple ruptures of the penetrating hepatic capsular arteries. It was suggested that these findings are not rare in cases of subcapsular hematoma; however, they have received little attention

    Late intrahepatic hematoma is a rare complication of the transjugular intrahepatic portosystemic shunt (TIPS) procedure. We describe a patient with Budd-Chiari syndrome (BCS), who presented with a large inrahepatic hematoma 13 days after TIPS. Review of the literature reveals only two previous cases, both occurring in patients with BCS and presenting after a similar time interval. This potentially serious complication appears to be specific for TIPS in BCS

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

    A renal subcapsular hematoma rarely occurs without a history of trauma. It has been reported as a complication of urological interventions and also reported to occur spontaneously in patients with renal malignancies. However, there are no previous reports of renal subcapsular hematomas occurring in connection with abdominal angiography. We report here a case of a renal subcapsular hematoma that developed and was recognized during abdominal angiography for treatment of hepatocellular carcinoma (HCC). An 80-year-old male was referred to our hospital for transarterial embolization for multiple HCCs. His past medical history included hypertension. His laboratory data showed slightly decreased number of platelets and hepaplastin test due to liver cirrhosis. When computed tomography angiography was performed, a 7-cm subcapsular hematoma developed and was recognized over the right kidney during the procedure. He was successfully managed supportively with blood transfusion, tranexamic acid and antibiotics. Since thrombocytopenia and hypertension are reportedly risk factors for hematoma formation, careful manipulation is required during angiography in HCC patients with liver cirrhosis and hypertension. It must be kept in mind that rare complications, such as a renal subcapsular hematoma, can happen during abdominal angiography for diagnostic and interventional treatment of HCC. PMID:26183639

  19. Clinical appraisal of stereotactic hematoma aspiration surgery for hypertensive thalamic hemorrhage

    International Nuclear Information System (INIS)

    Three hundred and four patients with hypertensive thalamic hemorrhage were managed by medical treatment, ventricular drainage, or CT-controlled stereotactic aspiration surgery (AS). The therapeutic results of the 6-month outcome were analyzed and correlated with the volume of the hematoma. A hematoma volume of 20 ml was thought to be the critical size in determining whether the outcome would be favorable or unfavorable. Indications for AS are suggested as follows. In patients with a small-sized hematoma having a volume of less than 10 ml use of AS should be restricted to patients with severe paralysis or other neurological complications and the elderly (aged 70 years or older). For patients with a medium-sized hematoma having a volume between 10 ml and 20 ml, AS is indicated for patients having severe paralysis and disturbances of consciousness. For patients with a large-sized hematoma having a volume of 20 ml or more, AS increases not only the survival rate of patients but also reduces the number of bedridden patients. We conclude that AS opens up a new avenue of surgical treatment for hypertensive thalamic hemorrhage, which has been no indication for hematoma evacuation by conventional craniotomy. (author)

  20. Hematoma and MR imaging at 0.15 T. A review of 100 cases

    International Nuclear Information System (INIS)

    One hundred hematomas were examined by magnetic resonance imaging (MRI) at 0.15 T, all explored in SEpT1 and most in SEpT2. The number of cases examined in the acute phase during the first 48 hours was low: 8 cases. At this SEpT1 period the hematoma appears of elevated signal with good muscle contrast but without contrast in hepatic and cerebral parenchyma. In a weighted T2 sequence, the intense signals of cerebral edema and plasma or serum enables detection of the encephalic lesion. Findings from 68 hematomas observed in the subacute or chronic phase suggest that their appearance is pathognomonic with visualization in SEpT1 of a crown of an intense signal at least equal to that of fat. The only difficulty at this period is the discovery of a hematoma within the fat: orbital, retroperitoneal... The collection of a subdural hematoma usually appears homogeneous, the intensity of the signal varying with red cell concentration and time. In the soft tissues, the intensity of signal is a function of concentration of hemoglobin and its derivatives and of volume of serious effusion. Images of 24 hematomas during the sequelae phase confirmed the appearance of a ''biochemical shell'' without signal in SEpT2 and allowed detection of the hematic contents of an occupying process even after long periods, sometimes after one year

  4. Acute intramural hematoma of ascending aorta. CT findings and clinical outcome

    International Nuclear Information System (INIS)

    The purpose of this study was to describe the CT findings and clinical outcomes of nineteen patients with acute intramural hematoma (IMH) of the ascending aorta. Six patients underwent surgery on the emergency basis (3 patients) due to cardiac tamponade (n=2) and dilated aorta (n=1), and on the elective basis (3 patients) due to patent and enlarging false lumen. Among the 13 patients with medical management, four patients died from complications of IMH during the follow-up period (2 days-2.5 years). Transition to aortic dissection or enlargement of an intimal tear was noted in 5 patients (31%) in 1 to 6 weeks after onset. Three patients died of causes not related to IMH. Six patients had been alive 2 to 9 years after onset. Retrospective review revealed 10 patients (53%) as possible surgical candidates, and the other 9 patients as medically treated patients in the long-term follow-up. The surgical group showed cardiac tamponade or shock in 6 patients on admission and had pericardial effusion in all the patients on the initial CT scan. In the patients with acute IMH of the ascending aorta, surgery should be considered for severe clinical symptoms, pericardial effusion and large size of the ascending aorta (more than 4 cm) on CT scan, and for converting to a typical type A aortic dissection. CT scan had a major role in making an early diagnosis, in depicting a dangerous sign, and in monitoring its progression or resolution of IMH. (author)

    Full Text Available Access to deep-seated brain lesions with traditional fixed and rigid brain retractors can be difficult without causing significant trauma to the surrounding brain. Tubular retractors offer an advantage of low retracting pressure. We developed a new inexpensive and simple tubular retractor which requires very small cortisectomy. The new tubular retractor was made up of silicone with inner diameter of 15, 18 and 23 mm and outer diameter of 17, 20 and 25 mm, respectively. This tube (1 mm thick was cut in longitudinal direction. It was folded to make a small-diameter tube so that it could be introduced through a small cortisectomy. Margins of cortisectomy were gently and slowly retracted by Killian nasal speculum. Folded retractor, held by tissue forceps, was introduced inside the opened Killian nasal speculum. Tissue forceps and nasal speculum were removed leaving tubular retractor in place, which comes back to its normal tubular configuration after release. Surgery was performed using rigid Karl Storz 0° telescope (30 cm long and 4 mm in diameter or microscope. Near-total removals of intracerebral hematomas, 37 hypertensive and 3 traumatic, was done using this retractor without any complication.

    A non-invasive microwave device for the detection of epi/subdural hemorrhaging (hematoma) is under current development. The final device will be highly portable and allow real time assessment of head injuries, thereby satisfying early detection needs of the field technician as well as providing a tool for repetitious monitoring of high-risk individuals. The device will adopt the advanced technology of micropower impulse radar (MIR) which is a state of the art low cost ultra wide band (UWB) microwave radar developed here at LLNL. It will consist of a MIR transmitting and receiving module, a computer based signal processing module, and a device-to-patient signal coupling module--the UWB antenna. The prototype design is being guided by the needs of the patient and the practitioner along with the prerequisites of the technology including issues such as the specificity of the device, efficacy of diagnosis, accuracy, robustness, and patient comfort. The prototype development follows a concurrent approach which .includes experiments designed to evaluate requirements of the radar and antenna design, phantom development to facilitate laboratory investigations, and investigation into the limits of adapting pre-existing non-medical MIR devices to medical applications.

    International Nuclear Information System (INIS)

    Two patients had interhemispheric subdural hematoma (ISH) without clinical signs or symptoms characteristic of ISH. The first patient, a 74-year-old woman with 7 years' history of Parkinson's disease, complained of unresponsiveness and akinesia. The treatment for suspected worsening of the disease failed to improve her conditions. Computed tomography (CT) showed hyperdensity along the falx from the frontal falx over the tentorium. Subsequent CT on the 23rd hospital day showed disappearance of hyperdensity, confirming ISH. The second patient, a 76-year-old woman with multiple cerebral infarction, was referred for loss of consciousness and vomiting. Neurological examination failed to reveal additional or augmented neurological deficits. Computed tomography showed a right parasagittal thin crescent hyperdensity with a flat medial border and a convex lateral border, extending from the anterior falx to the mid-falx. The hyperdensity disappeared on the 47th hospital day. These findings suggest the usefulness of CT as the only procedure when ISH features are not seen. (Namekawa, K.)

    Full Text Available Background: The role of subchorionic hematoma (SCH in the first trimester of pregnancy remains open for discussion. Some authors claim that SCH does not affect the pregnancy; others have found that it is a serious risk factor for adverse pregnancy outcome. The objective of the present study was to explore the outcomes of pregnancy in patients with SCH diagnosed in the first trimester. Methods and Results: The study involved 194 pregnant women who were in terms of 6 to12 weeks: 115 women with SCH (Group 1 and 79 apparently healthy pregnant women (Group 2. A missed miscarriage was observed in 27/23% women of Group 1 and in 4/5% of Group 2 (P<0.05, recurrent threat of miscarriage in 27/23% and in 4/5%, recurrent bleeding in 14/12% and 2/3%, and the short cervix syndrome in 22/19% and 5/6% women, respectively. Conclusion: The results of our study show that the presence of SCH adversely affects the first half of pregnancy, leading to recurrent threatened abortion, recurrent threat of miscarriage, missed miscarriage until 12 weeks of gestation, and the short cervix syndrome.

  9. Diagnosis of isodense subdural hematomas by computed tomography

    International Nuclear Information System (INIS)

    Fifteen cases of surgically proved isodense subdural hematoma on CT were studied in the Hanyang University Hospital from Feb. 1979 to Aug. 1981. The medical records and CT films were reviewed. The results were as follows: 1. The age distribution is broad from 12 years to 73 years old. The peak age incidence is in the 6th decade. The most of the cases were male. 2. 12 out of 15 cases were conscious at the time of CT examination, and the rest of them were stuporous or unconscious. 3. 10 out of 15 cases had historys of head injury. In 6 cases the intervals between head injury and CT examination were more than 3 weeks. 4. Skull radiograms showed a fracture in the right frontal bone in 1 case. 5. In computed tomograms shifting of mid-line structures were observed in 14 out of 15 cases, compression and local deformities of the lpsilateral lateral ventricles in 14 cases, dilatation of the contralateral lateral ventricles in 14 cases, unilateral effacement of the cortical sulci in 14 cases

    Intracranial subdural haematoma has been reported to be an exceptionally rare complication of accidental dural puncture. An accidental lumbar dural puncture occurred in a 36-yr-old male undergoing orthopedic knee surgery. On the morning after the operation, the patient complained of severe occipital headache, although this was relieved with loxoprofen and rest. This was assumed to be a postdural puncture headache (PDPH) because it had a postural component (it was worse on sitting up). On the third day after the operation, the patient developed a severe diffuse headache together with nausea, which did not subside with analgesia and bed rest. Magnetic resonance imaging of the head showed a small acute subdural hematoma in the bilateral temporooccipital region with no mass effect. The patient was conscious and oriented. There was no focal neurological deficit. The patient was managed conservatively with bed rest and intravenous fluids. His condition improved without surgical decompression and was discharged on the 40 th day after the operation. Severe and prolonged PDPH shoud be considered as a warning sign of an intracranial complication. PMID:15852633

  11. Clinical study of cerebral blood flow in bilateral chronic subdural hematoma measured by 99mTc-HMPAO SPECT

    International Nuclear Information System (INIS)

    Cerebral blood flow (CBF) in 34 patients with bilateral chronic subdural hematoma was measured by 99mTc-HMPAO SPECT before operation. The regional CBF was measured in 26 regions of the 10 cortical regions, putamen, thalamus and cerebellar hemisphere on both sides. According to the thickness of subdural hematoma, the thicker hematoma side was measured and examined as the thick hematoma side, and the other side as the thin hematoma side. Thirty four cases with bilateral chronic subdural hematoma were classified into four groups on the basis of clinical symptoms :13 cases with headache (headache group), 10 cases with hemiparesis (hemiparesis group), 5 cases with tetraparesis (tetraparesis group) and 6 cases with consciousness disturbance or dementia (consciousness disturbance group), and into two groups according to the degree of midline brain shift on MRI: 14 cases of non-shifted group and 20 cases of shifted group. The average CBF of 34 patients in each region indicated a regional CBF reduction in the frontal, parietal and occipital cortices on the thin hematoma side, and in the putamen on the thick hematoma side. In the headache group, the regional CBF reduction on the thin hematoma side was found in the frontal, parietal and occipital cortices compared with the corresponding regions on the thick hematoma side, and in thalamus on the thick hematoma side. In the hemiparesis and tetraparesis groups, there was no statistically significant CBF reduction between the thick and thin hematoma sides. In the consciousness disturbance group, the CBF reduction in whole brain was remarkably significant. By the degree of the midline brain shift, the CBF reductions between the thick and thin hematoma sides were observed. Namely, in the shifted group, the CBF reductions were noted in the frontal, parietal and occipital cortices in the thin hematoma side, and in the putamen in the thick hematoma side. We concluded that the CBF reduction of bilateral chronic subdural hematoma was bilaterally found in the hemiparesis and tetraparesis groups, and which was finally observed in whole brain in the consciousness disturbance group.

    Delayed umbilical cord separation in association with neonatal alloimmune neutropenia is reported. Delayed umbilical cord separation has been described in association with defects in neutrophil function. The present case indicates that deficiency in neutrophil number should also be considered as a cause of delayed cord separation.

    Chronic subdural hematoma (CSDH) is a common neurological occurrence in the elderly population with significant impact on the quality of life and work. Studies have attempted to determine the risk factors and pathophysiological mechanisms of CSDH using models in numerous mammalian species. To date, these animal models have only been able to reproduce limited durations of hematoma which does not accurately reflect the chronic state of CSDH. To address some of these challenges we modified a rat model of CSDH using two consecutive injections of autologous blood resulting in a hematoma of more than three weeks. We observed inflammatory and angiogenic changes related to the development and recovery of CSDH. In this study the technique for producing a CSDH in a small animal model had a success rate of 78.13%. The hematoma was sustainable up to 24 days. Hematoma resolution was associated with a gradual decrease in local pro-inflammatory factors and gradual increase in anti-inflammatory factors as well as proliferation and subsequent maturation of newly formed vessels. These events were also associated with improved behavioral outcome. Expression of anti-inflammatory cytokines also paralleled reabsorption of the hematoma. Reduction in hematoma size was also associated with neurological recovery. These data suggest that vessel maturation and anti-inflammatory pathways may contribute to the resolution of CSDH and neurological recovery. The regulation of the two mechanisms is a potential target for the treatment of CSDH. The modified model of rat CSDH demonstrated a high level of reproducibility in our hands and may be useful in future CSDH studies. PMID:26315377

    2015-04-01

    This paper argues that those who emphasise that designers and engineers need to plan for obsolescence are too conservative. Rather, in addition to planning for obsolescence, designers and engineers should also think carefully about what they could do in order delay obsolescence. They should so this by thinking about the design itself, thinking of ways in which products could be useful and appealing for longer before becoming obsolete, as well thinking about the wider context in terms of the marketing of products, and also the social and legal. The paper also considers objections that these suggestions are unrealistically idealistic, failing to recognise the economic realities. I respond to these objections appealing to research in advertising, psychology, cognitive linguistics, philosophy, history, and economics, as well as drawing on the Statement of Ethical Principles developed by the Royal Academy of Engineering and the Engineering Council.

    We consider the effect of distributed delays in neural feedback systems. The avian optic tectum is reciprocally connected with the nucleus isthmi. Extracellular stimulation combined with intracellular recordings reveal a range of signal delays from 4 to 9 ms between isthmotectal elements. This observation together with prior mathematical analysis concerning the influence of a delay distribution on system dynamics raises the question whether a broad delay distribution can impact the dynamics of neural feedback loops. For a system of reciprocally connected model neurons, we found that distributed delays enhance system stability in the following sense. With increased distribution of delays, the system converges faster to a fixed point and converges slower toward a limit cycle. Further, the introduction of distributed delays leads to an increased range of the average delay value for which the system's equilibrium point is stable. The enhancement of stability with increasing delay distribution is caused by the int...

    Spinal subdural hematoma (SDH) is a rare condition and can be caused by several factors. Concomitant cranial and spinal SDH is even much less common. We present a 77-year-old male patient with lower back pain, paraparesis, and urinary retention following a sudden onset headache. Imaging revealed concomitant cranial and spinal SDH related to cerebral venous thrombosis (CVT) associated with hemorrhagic venous infarct. Laboratory examinations were consistent with polycythemia vera. There was no history of trauma and previous cranial surgery. Brain angiography did not reveal any evidence of arteriovenous fistula or vascular malformation. Since lower back pain occurred shortly after the headache and there was no other reasonable explanation for spinal hemorrhage, we suppose that the mechanism of spinal SDH is the migration of blood from the intracranial compartment. Therefore, this is the first report of concomitant spinal SDH and cerebral hemorrhage associated with CVT in a patient with myeloproliferative disease. PMID:20671855

  2. Comparison of clinical outcomes of intraventricular hematoma between neuroendoscopic removal and extraventricular drainage

    International Nuclear Information System (INIS)

    The efficacy of treatment for intraventricular hematoma by neuroendoscopic surgery and extraventricular drainage was compared in 10 patients with intraventricular hematoma and hydrocephalus who underwent neuroendoscopic surgery (endoscopic group), and eight patients with intraventricular hematoma and hydrocephalus treated with extraventricular drainage (EVD group). The outcomes in each group were assessed retrospectively using the Graeb scores on the pre- and postoperative computed tomography (CT), duration of extraventricular drainage, requirement for a shunt operation, and modified Rankin scale score at 12 months. The Graeb scores on the preoperative CT were not significantly different between the two groups, but the duration of catheter placement was significantly shorter (69.3%) in the endoscopic group (2.7 days) than in the EVD group (8.8 days). None of the patients in either group required a shunt procedure for communicating hydrocephalus 12 months after surgery. Neuroendoscopic removal is a safe and effective procedure for intraventricular hematoma. Advantages include rapid removal of hematoma in the ventricular systems and reliable improvement of non-communicating hydrocephalus in the acute phase. The procedure resulted in faster removal of the catheter in the postoperative period and earlier patient ambulation. (author)

  3. Retroperitoneal hematoma following rofecoxib and enoxaparin coadministration in a patient with atrial fibrillation

    International Nuclear Information System (INIS)

    There are very few published reports implicating enoxaparin as a factor in retroperitoneal hematoma. We report a patient who developed a retroperitoneal hematoma after using enoxaparin for paroxysmal atrial fibrillation. A 72 year old man was admitted with a history of low back pain, radiating beyond the back to the buttocks. His medical history was positive for bilateral knee osteoarthritis. On his physical examination his vital signs were: temperature 36.8, blood pressure 100/70 mm Hg, pulse 72/min, respiratory rate 16/min. X-ray of both the knees showed bilateral osteoarthritic changes. Computerized tomography scan of the spine showed lumbar spinal stenosis and he was referred to a Neurosurgeon, who finds the patient not fit surgical intervention. ECG showed atrial fibrillation. He was given enoxaparin one mg/kg every 12 hour and digoxin. Abdominal computed tomography revealed a right retroperitoneal hematoma and no aortic aneurysm was noted and enoxaparin and rofecoxib were discontinued. His general condition improved. The factors that increase the risk of bleeding in patients receiving enoxaparin are use of high doses of enxaparin, advanced stage, renal impairment, and the concomitant use of drugs affecting hemostasis. Retroperotoneal hematoma should be considered in the different diagnosis in patients receiving enoxaparin and experiencing unexplained decreases in hemoglobin and hematocrit. In the order of precedence of radiologic diagnostic procedures for fast diagnosis of a retroperitoneal hematoma, abdominal CT-scan is the preferred method

    A 71 year-old hypertensive right-handed man presented a small intracerebral haematoma limited to the left subthalamic nucleus that resulted in right hemiballismus and a neurobehavioral disinhibition syndrome. The latter associated logorrhoea and euphoria, but there was no frontal signs nor mental confusion. The patient kept full insight into his mental change, that contrasted with his prior personality. Hemiballismus and the manic-like state resolved within 2 months. This case and some others from the literature illustrated that a focal lesion in the basal ganglia could result in manic-like affective change, and that a relation did exist between hyperkinetic syndrome and euphoria. Our case contrasted with most of the published cases of neurobevioral changes following basal ganglia discrete lesions, expressing as hypokinesia, apathy and loss of motivation. With reference to the functional circuits linking the frontal cortex and the basal ganglia, as described by Alexander, this syndrome of combined disinhibition of motricity, speech and affect could involve either the lateral orbito-frontal or the anterior cingulate loops, more especially the indirect pathways travelling through the subthalamic nucleus, lesion of which is known to disinhibit thalamo-cortical activity.

  6. The clinical and imaging characteristics of delayed encephalopathy after acute carbon monoxide poisoning

    International Nuclear Information System (INIS)

    Objective: To discuss the clinical and imaging characteristics of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: The clinical data of 14 patients with DEACMP were respectively analyzed. Results: Initial symptom included mentally falling (MMSE rate < 20 points) in 14 patients (100%), incontinence of urine in 11 patients (78%). Relatively significant increase of hematoma (HCT) (average level 0.503±0.027) was found in 6 patients. Three kinds of brain magnetic resonance imaging (MRI) appearance including diffuse white matter lesion, cortical lesion and basal nuclei lesion often existed in association. Therapy for improving circulation was given in 14 patients, and therapy with hormone was given in 9 patients; with 85% improvement rate. 5 patients without hormone therapy but with improving circulation therapy also received improvement. Conclusion: High level of HCT might be one of the causes of DECACMP due to acute disturbance of brain micro-circulation.. Close monitoring the change of HCT levels should be adopted for at least 3-6 months during therapy. Therapy for improving circulation and for anti-agglutination of platelets should be performed besides the routine high-tension oxygen therapy. Low FA value on DTI indicates the occurrence of a demyelization change in the brain long tract fibers, which indicated therapeutic effect of hormone treatment. And, therefore it would be better to perform DTI scan before therapy for individualized therapy. (authors)

    JUSTIFICATIVA E OBJETIVOS: A cefaléia pós-punção da dura-máter é complicação bastante conhecida das anestesias subaracnóidea e peridural, e o tratamento mais difundido é o tampão sangüíneo. O tampão sangüíneo alivia totalmente a cefaléia na grande maioria dos pacientes, e nos demais não há melhora ou, apenas, melhora parcial. Nesses casos, é prudente buscar diagnósticos diferenciais, como o hematoma subdural ou pneumoencéfalo. Os métodos de imagem são extremamente úteis nessas situações. O ob...

    Laparoscopic cholecystectomy is now a standard procedure for cholecystolithiasis because of its minimally invasive nature compared to the conventional method. However, severe complications that have never been seen for open surgery have also been reported. Here, we report the case of a 28-year-old woman who underwent laparoscopic cholecystectomy and then developed a ruptured subcapsular hematoma. On postoperative day 1, she developed shock, and postoperative bleeding was suspected. During re-operation, a ruptured subcapsular hematoma of the whole right lobe of the liver with active bleeding was found, and hemostasis was achieved. In this case, it was assumed that the rupture of the subcapsular hematoma was due to compression of the liver by the clamp for retrieving the spilled gallstones during the first operation and perioperative administration of nonsteroidal anti-inflammatory drugs.

    Full Text Available We report a case of retroperitoneal hematoma presenting as femoral nerve pulsy on antiplatelet therapy. The patient, a 78-year-old man who had undergone antiplatelet treatment using ticlopidine, was admitted to our hospital with complaints of sudden-onset low abdominal and back pain. Computed tomography showed an iso-density mass in the right retroperitoneum within the psoas muscle. We made a diagnosis of retroperitoneal hematoma compressing the femoral nerve and performed an operation to remove the hematoma in order to decompress the femoral neuropathy. Postoperatively, the patient rapidly recovered from the femoral neuropathy. In the particular case in which no antagonist against the ticlopidine is available, surgical decompression could produce a good outcome.

    We present the first report of an intraventricular encapsulated hematoma, mimicking cavernous malformation on imaging and gross lesion appearance. A 47-year-old female on anticoagulation therapy for atrial fibrillation presented with left upper extremity apraxia, neglect, and mild gait imbalance. Her brain CT scan and MRI revealed multilobulated lesions involving the choroid plexus in the atria of both lateral ventricles. The intraoperative appearance was that of encapsulated mass, with blood clots at different stages of liquefaction and organization, all consistent with the gross appearance of a cavernous malformation. However, histopathologic examination demonstrated hematoma with components at different ages, and normal vessel infiltration without any hint of cavernous malformation histology, or underlying neoplasia. Encapsulated hematoma should be considered in the differential diagnosis of hemorrhagic intraventricular masses. PMID:21435884

  11. Multifocal subdural hematomas as the presenting sign of acquired hemophilia A: a case report

    Science.gov (United States)

    2014-01-01

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

    2015-01-01

    Full Text Available Intraoral hematoma secondary to systemic anticoagulant therapy is rare, but it is a potentially fatal condition requiring immediate medical management. Case report: Here we report a case of self-inflicted hematoma in the anterior maxillary gingival region in a 65year old female cardiac patient who was on systemic anticoagulant therapy with a poor periodontal condition, manifesting as a periodontal swelling for a period of one week. Oral anticoagulant therapy is considerably imperative to prevent thromboembolic complications in various medical conditions, in such patients there are chances for spontaneous bleeding or hematoma by means of minor trauma due to sharp teeth or dental prosthesis in the mouth leading to life threatening complications such as partial or complete airway blockage. Therefore,directives about possible bleeding complications secondary to anticoagulant drugs in the oral cavity and the importance of maintaining oral health hygiene are necessary for the patient.

    Full Text Available Introduction: Nasopharyngeal carcinoma (NPC has the propensity to develop distant metastases at a high rate and with poor prognosis. The metastatic sites are usually multifocal and involve the bones, lungs, liver and distant lymph nodes. The management of metastatic disease is essentially palliative and is based on radiochemotherapy. Methods: A 50-year old man with a huge hematoma in the liver derived from a diagnosed NPC was treated with intermittent drainage of the hepatic hematoma for abdominal decompression, and the cavity was packed with omentum. In addition, 2 suspected metastatic lesions were excised. Neoadjuvant radiochemotherapy followed by concurrent chemotherapy was administered. Results: After surgical treatment of the huge hematoma, the suspect sites in the liver were diagnosed as metastatic carcinoma, similar to the primary tumor. Several months later, bone metastatic lesions in the vertebra and ossiliaca dextra were detected due to distant metastasis. Conclusion: Treatment of metastatic NPC is essentially palliative and survival is usually poor.

  14. Practical CT classification for thalamic hemorrhage. Relationship between localization of hematoma and prognosis

    International Nuclear Information System (INIS)

    The study was designed to establish CT classification for predicting prognosis of thalamic hemorrhage. A retrospective analysis was made on CT scans from 100 patients with hypertensive thalamic hemorrhage less than 4 cm. Four lines were drawn on axial CT scans at the level of the pineal body: (A) line between the lateral edge of the anterior horn and the midpoint of the third ventricle; (B) vertebral line to the sagittal line from the midpoint of the third ventricle; (C) line between the lateral edge of the trigone and the midpoint of the third ventricle; and (D) line between the lateral edge of the anterior horn and the lateral edge of the trigone. According to the lateral extension, the location of hematoma fell into three types: anterior type in which the center of hematoma was located between lines A and B (type A); posterior type in which the center of hematoma was located between lines B and C and external margin of hematoma was localized medial to line D (type P); postero-lateral type in which the center of hematoma was located between lines B and C and showed lateral extension beyond line D (type PL). Severe hemiparesis was observed in 15.3% for type A, 21.8% for type P, and 59.3% for type PL. Good prognosis was seen in 84.7% for type A, 70.9% for type P, and 12.5% for type PL. Acute disturbance of consciousness was significantly observed in patients with medial extension of hematoma (86.4%) as compared with those without it (21.4%). These results indicated that CT classification is a simple means for predicting functional outcome of motor paresis and consciousness disturbance in patients with thalamic hemorrhage. (N.K.)

    Few case reports of encapsulated intracranial hematoma (EIH) exist, and the mechanisms underlying the onset and enlargement of EIH remain unclear. Here, we report on a 39-year-old woman with an EIH that repeatedly hemorrhaged and swelled and was ultimately surgically removed. In June 2012, the patient visited her local doctor, complaining of headaches. A magnetic resonance imaging (MRI) scan identified a small hemorrhage of approximately 7 mm in her right basal ganglia, and a wait-and-see approach was adopted. Six months later, her headaches recurred. She was admitted to our department after MRI showed tumor lesions accompanying the intermittent hemorrhaging in the right basal ganglia. After admission, hemorrhaging was again observed, with symptoms progressing to left-sided hemiplegia and fluctuating consciousness; thus, a craniotomy was performed. No obvious abnormal blood vessels were observed on the preoperative cerebral angiography. We accessed the lesion using a transcortical approach via a right frontotemporal craniotomy and removed the subacute hematoma by extracting the encapsulated tumor as a single mass. Subsequent pathological examinations showed that the hematoma exhibited abnormal internal vascularization and was covered with a capsule formed from growing capillaries and accumulating collagen fibers, suggesting that it was an EIH. No lingering neurological symptoms were noted upon postoperative follow-up. This type of hematoma expands slowly and is asymptomatic, with reported cases consisting of patients that already have neurological deficits due to progressive hematoma growth. Our report is one of a few to provide a clinical picture of the initial stages that occur prior to hematoma encapsulation. PMID:26500543

  16. Time course of early postadmission hematoma expansion in spontaneous intracerebral hemorrhage

    BACKGROUND AND PURPOSE: Early hematoma expansion (EHE) in patients with intracerebral hematoma is a promising treatment target. To date, the time course of EHE has remained poorly described. We prospectively investigated the time course of EHE. METHODS: We included consecutive patients presenting spontaneous intracerebral hematoma within 4.5 hours. On admission, patients underwent noncontrast computed tomography (CT) and CT angiography. Serial hematoma volume estimations by transcranial B-mode ultrasound were effected through the contralateral transtemporal bone window by obtaining sagittal, transversal, and coronal diameter and calculating the ABC/2-formula. National Institute of Health Stroke Scale and transcranial B-mode ultrasound were performed consecutively every 30 minutes during the first 6 hours and from 6 to 12 hours every 2 hours. Follow-up CT and ultrasound were performed after ?24 hours. RESULTS: Twenty-five patients with intracerebral hematoma were included; mean (SD) time from onset to CT was108.6 (45.7) minutes. Ten (40%) patients had EHE. In patients with a final clinically significant hematoma expansion >12.5 mL, all EHE occurred within 6 hours after admission scan. EHE in spot sign positive patients continued during the first 5 hours after CT angiography. In spot sign-negative patients, no significant EHE was observed (Friedman test, P=0.476). Neurological deterioration occurred in 5 (20%) patients and was well temporally correlated with EHE. Transcranial B-mode ultrasound demonstrated good volume estimation compared with the follow-up CT with a maximum absolute volume deviation within 7 mL and minimal systematic error (mean deviation, 1.3 [confidence interval, -0.1 to 2.6] mL). CONCLUSIONS: EHE was reliably reflected by transcranial B-mode ultrasound and mainly occurred within the first 7 to 8 hours after symptom onset.

  17. Mutation of EMG1 causing Bowen–Conradi syndrome results in reduced cell proliferation rates concomitant with G2/M arrest and 18S rRNA processing delay

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Bowen–Conradi syndrome (BCS is a lethal autosomal recessive disorder caused by a D86G substitution in the protein, Essential for Mitotic Growth 1 (EMG1. EMG1 is essential for 18S rRNA maturation and 40S ribosome biogenesis in yeast, but no studies of its role in ribosome biogenesis have been done in mammals. To assess the effect of the EMG1 mutation on cell growth and ribosomal biogenesis in humans, we employed BCS patient cells. The D86G substitution did not interfere with EMG1 nucleolar localization. In BCS patient lymphoblasts, cells accumulated in G2/M, resulting in reduced proliferation rates; however, patient fibroblasts showed normal proliferation. The rate of 18S rRNA processing was consistently delayed in patient cells, although this did not lead to a difference in the levels of 40S ribosomes, or a change in protein synthesis rates. These results demonstrate that as in yeast, EMG1 in mammals has a role in ribosome biogenesis. The obvious phenotype in lymphoblasts compared to fibroblasts suggests a greater need for EMG1 in rapidly dividing cells. Tissue-specific effects have been seen in other ribosomal biogenesis disorders, and it seems likely that the impact of EMG1 deficiency would be larger in the rapidly proliferating cells of the developing embryo.

    We report a case of a cystic abdominal mass on ultrasound which presented a diagnostic dilemma at 32 weeks gestation. A presumptive antenatal diagnosis of a subcapsular liver hematoma (SCH) was made based on the location and ultrasound appearance similar to SCH seen in pediatric and adult patients. Sequential evaluation of the mass showed an evolving ultrasound appearance which reinforced our initial impression of a subcapsular hematoma of the fetal liver. Postnatal ultrasound confirmed the resolving SCH as well as a previously undetected echo bright lesion characteristic of an infantile focal hemangioma directly adjacent to the resolving SCH. A review of the literature is provided. PMID:26495185

    Mrs. AB, a 40-year-old woman, in her second pregnancy had a spontaneous hematoma of liver of unknown etiology that was managed successfully conservatively under the umbrella of the multidisciplinary care. The subcapsular hematoma was diagnosed at 31 weeks gestational age while she was being investigated because of sudden and gross drop of hemoglobin from 12.8 to 8 g/dl in 2 weeks duration. The dilemma remains as how to manage her future pregnancies and what are the risks of recurrence. PMID:20001572

  1. Methodological difficulties of angiographic diagnosis of traumatic intracranial hematomas in city hospital

    International Nuclear Information System (INIS)

    Experience in the use of carotid angiography in a city hospital was analysed. A high diagnostic value of cerebral angiography in a severe craniocerebral trauma complicated by intractanial hematomas, was shown. X-ray equipment which was available to city and district hospitals, was employed for cerebral angiography. Difficulties of angiographic examination, mainly of technical nature or associated with the interpretation of angiograms, were analysed. Opportunities for their practical elimination were shown. Advantages of angiography in early detection of intracranial hematomas of different sites were stressed

    Subperiosteal hematoma of the orbit is a rare disease and most of the cases occur in young adult males as a result of direct facial or orbital trauma. In the absence of direct facial or orbital trauma, nontranmatic subperiosteal orbital hematoma has rarely been reported in association with a sudden elevation of cranial venous pressure or venous congestion, systemic diseases associated with a bleeding diathesis and paranasal sinusitis. We report here on a rare case of subperiosteal orbital hemaboma associated with ethmoid sinusitis, as was seen on CT imaging.

    We present a 35-year-old man with an extradural hematoma extending bilaterally across the midline from the foramen magnum to the vertex who completely recovered following surgery. Because of the extent of the fluid collection, computed tomographic scanning proved invaluable in facilitating the planning of our surgical approach. He had a long history of alcohol abuse and there were features suggesting preexisting alcoholic brain atrophy in his postoperative computed tomography scan. The possible relationship of this finding to the size of the hematoma and the outcome is discussed. PMID:3603352

    Retroperitoneal hematoma is a rare complication of psoas catheter placement, typically occurring several days after placement and in the setting of anticoagulation. We present the case of a patient with a history of myeloproliferative thrombocytosis receiving aspirin therapy who underwent total hip arthroplasty with preoperative psoas catheter placement complicated by immediate development of a large retroperitoneal hematoma. It is likely that the combination of aspirin therapy and thrombocytosis paradoxically placed the patient at increased risk for hemorrhagic complications. Regional techniques should be used cautiously in patients with myeloproliferative disorders, even in the presence of supraphysiologic platelet counts. PMID:26779603

    Background: Persistent/recurrent extra-axial hemorrhage may occur after decompression of a subdural hematoma (SDH) followed by an immediate replacement of bone flap. A fenestration of the bone flap may encourage extra-axial fluid absorption; however, the literature has not explored this technique. Methods: Forty-four consecutive patients who underwent surgical decompression of SDH with immediate replacement of bone flap were divided into two groups: Fenestration (F), n = 33, and no fenestration (NF), n = 11. Fenestration involves placement of twist drill holes 1–2 cm apart throughout the bone flap. Clinical data (age, sex, history of antiplatelet/anticoagulation [AA], and presence of drains) were collected. The size of bone flap, postoperative volume, and midline shift (MLS) were measured. A univariate analysis was performed for continuous variables; Fisher's exact test was performed for categorical variables. Results: For postoperative volume, NF group exhibited 94.4 ± 15.5 cm3, while F group exhibited 47.3 ± 15.5 cm3 (P = 0.04); no AA exhibited 62.9 ± 12.3 cm3, while AA exhibited 100.5 ± 19.0 cm3 (P = 0.07); no drains exhibited 110.1 ± 29.6 cm3, while drains exhibited 63.0 ± 9.1 cm3 (P = 0.14). For postoperative MLS, NF group exhibited 4.8 ± 1.1 mm, while F group exhibited 2.5 ± 1.1 mm (P = 0.16); no AA exhibited 2.3 ± 1.0 mm, while AA exhibited 5.8 ± 1.4 mm (P = 0.048); no drains exhibited 4.6 ± 2.2 mm, while drains exhibited 3.8 ± 0.7 mm (P = 0.70). Accounting for fenestration status and AA status: For F group, AA status did not correlate with postoperative volume or MLS significantly; for NF group, history of AA exhibited higher postoperative value 129.2 ± 26.5 cm3, compared to no history of AA at 59.5 ± 16.2 cm3 (P = 0.03). Conclusion: Our results suggest that fenestration prior to the immediate replacement of bone flap after surgical decompression of SDH has the potential to reduce extra-axial fluid accumulation.

Abstract in english Compression over right chambers in the early postoperative course after cardiac surgery in a fully or partially stable patient poses a challenge as to what approach to follow, especially regarding the best management of the situation. This report describes the case of a 54-year-old male patient with [...] a significant clinical history -including previous coronary artery bypass surgery-, who underwent mitral and aortic valve replacement (with bioprostheses), and tricuspid valve repair. Due to massive bleeding unresponsive to transfusion of blood products during surgery, the patient was re-explored in the operating room; a recombinant activated factor VII dose was infused as a result of diffuse bleeding. During postoperative course, the patient presented with high atrium pressure, in which an isolated compression due to hematoma was detected; initially a conservative approach was adopted. The patient was monitored under continuous transesophageal echocardiogram, and management was based on ventricular filling parameters, in addition to direct and continuous observation of the hematoma.

  9. Radiological image interpretation for hematoma and small tumors simulated in a head and neck phantom

    International Nuclear Information System (INIS)

    Subarachnoidal hemorrhages (HSA) are caused by aneurysms and their symptom usually becomes evident after a rupture. Nevertheless, there are situations in which the aneurysms compress a nerve or produce a bleed before the rupture happens, as consequence one alert signal like headache occurs. It, often occurs after minutes or weeks previous the major rupture. The main goal is to prevent a massive hemorrhage. Thus the Computer Tomography (CT) scan of skull provides a basic and specific function: to reveal the position where the hemorrhage was produced, guiding to a additional medical procedures. On the other hand, CT does not prevent the cerebral tumor development, but precise diagnostic for some symptoms such as vomits, nauseas, epileptic attacks, weakness in arms or legs, require this image protocol. CT has its fundamental importance to tumor detection. Indeed CT reveals its importance in the tumor early diagnosis. Specialized training in CT analysis shall be done. Ahead of a precise diagnosis to manager an early intervention, a CT diagnostic training is suitable for a favorable prognostic. In this context, focusing on propose of radiological inquires; a head and neck phantom will be used to simulate hematomas and cerebral tumors. Images of CT of skull will be used to identify these lesions physically implanted in phantom. The radiological response will be analyzed with the purpose of validation of the skull's CT diagnosis, for a double blind test. The diagnostic with non contrast CT shows only higher 5mm diameter subjects (tumors) identified by the double blind test. Hemorrhage is identified by only the administrator (single-blind test). As conclusion, the author's launches the hypothesis that this object simulator shall provide assistance for specialized training on pathology interpretation on radiological images. (author)

    Shock wave lithotripsy (SWL) is the gold standard for the treatment of upper urinary tract stones. Despite being relatively non-invasive, SWL can cause renal hematoma (RHT). The aim of this study was to determine incidence and risk factors for RHT following SWL. 857 patients were included in a prospectively maintained database. The observation period spans from 2007 to 2012. 1,324 procedures were performed due to kidney stones. Treatment protocol included power ramping and shock wave frequency of 60-90 per minute as well as an ultrasound check within 3 days of SWL for all patients. Patients with RHT were analyzed, and treatment characteristics were compared with the complete population in a non-statistical manner due to the low event count. RHTs after SWL, sized between 2.6 × 0.6 cm and 17 × 15 cm, were verified in seven patients (0.53%). In four patients, the RHT was asymptomatic. Three patients developed pain after SWL treatment due to a RHT. In one patient surgical intervention was necessary due to a symptomatic RHT, the kidney was preserved. The risk of RHT following SWL treatment of kidney stones is about 0.5%. Clinically relevant or symptomatic RHTs occur in 0.23%, RHTs requiring surgical intervention are extremely rare. Older age and vascular comorbidities appear to be risk factors for the development of RHT. The technical characteristics of SWL treatment and intake of low-dose acetylsalicylic acid due to an imperative cardiologic indication do not appear to influence the risk. Prospective studies are warranted. PMID:24419328

  13. Clinical study of cerebral blood flow in unilateral chronic subdural hematoma measured by 99mTc-HMPAO SPECT

    International Nuclear Information System (INIS)

    Cerebral blood flow (CBF) measured by 99mTc-HMPAO SPECT before operation was studied in 60 patients with unilateral chronic subdural hematoma. The regional CBF was measured in 26 regions of the fronto-occipital 10 cortices, putamen, thalamus and cerebellar hemisphere on both sides. Sixty cases with unilateral chronic subdural hematoma were classified into four groups on the basis of clinical symptoms: 17 cases with headache (headache group), 34 cases with hemiparesis (hemiparesis group) and 9 cases with consciousness disturbance or dementia (consciousness disturbance group), and into three groups on the basis of the degree of midline brain shift on MRI: 7 cases of mild shift group, 24 cases of moderate shift group and 29 cases of severe shift group. The average CBF in 60 patients in each region indicated that the regional CBF was reduced in frontal, occipital cortices and cerebellum on the non-hematoma side, and in putamen and thalamus on the hematoma side. In the headache group, the regional CBF reduction on the non-hematoma side was found in only frontal and occipital cortices compared with the corresponding regions on the hematoma side. In the hemiparesis group, the regional CBF was reduced in frontal and occipital cortices on the non-hematoma side and in putamen and thalamus on the hematoma side. The part of CBF reduction in both hemispheres was also noted in the hemiparesis group. In the consciousness disturbance group, the CBF reduction was markedly noted in whole brain. The CBF reductions in frontal and occipital cortices on the non-hematoma side and in putamen, thalamus and cerebellum on the hematoma side was not mutually related with the degree of midline brain shift. We concluded that the disturbance of CBF in chronic subdural hematoma was started from frontal and occipital cortices on the non-hematoma side observed in the headache group, and which was extended to putamen and thalamus on the hematoma side and a part of both hemispheres observed in the hemiparesis group. And such disturbance was finally observed as the CBF reductions in whole brain in the consciousness disturbance group. (author)

    The subcapsular hematoma of the liver (SHL) are the results of injuries such as liver needle biopsy, liver trauma, pregnancy illnesses, parasitic diseases and others. The approach of these lesions depends on the various clinical presentations of subcapsular hematoma of the liver because it may be small with minimal clinical repercussion, managed only by ultrasound observation. In some situations the SHL may present large dimensions with hemodinamic instability. A case of subcapsular hematoma of the liver secondary to anesthetic intercostal blockade to control the postoperative pain after cholecystectomy is reported. A 34-year-old woman was submitted to intercostal anesthetic blockade after cholecystectomy for treatment of cholelithiasis. The blockade evolved with pain in right flank followed of mucocutaneous pallor and fall of the haematocrit and hemoglobin levels. At relaparotomy, subcapsular hematoma of the liver was proven and tamponed with compresses. The patient had good postoperative evolution being discharged from hospital, after removing the compresses. In conclusion, the intercostal anesthesic blockade, as any other medical procedure, is not exempt of complications. Therefore, it must be carried through in well selected cases; Anyway nowadays, there are efficient drugs for the control of postoperative pain. PMID:19735615

    Study Design?Case report. Objective?To describe a patient with a recurrent spontaneous spinal epidural hematoma (SSEH) during pregnancy that had spontaneous remission. Methods?A 27-year-old primigravida at 37 weeks' gestation suddenly felt a strong left shoulder pain without any trauma. She had a history of fenestration for a spontaneous cervical hematoma when she was 18 years old. An emergency magnetic resonance imaging revealed a recurrence of the cervical epidural hematoma at the C4-T1 level, but she had no paralysis. Results?The patient subsequently underwent a cesarean section and delivered a healthy male infant. Her spinal epidural hematoma disappeared. Multislice computed tomography showed no evidence for a vascular malformation or tumor. Three years after the initial cesarean section, she underwent a second one and delivered another male infant. Conclusions?We report on a rare case of recurrent SSEH during pregnancy with no neurologic deficits that was treated nonoperatively with close observation and resulted in spontaneous resolution. In such patients with no neurologic deficits, nonoperative management with close observation may be a reasonable alternative. PMID:26430600

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

  17. Intramural duodenal hematoma as a complication of therapy with Warfarin: a case report and literature review

    International Nuclear Information System (INIS)

    We report a case of a patient receiving chronic oral anticoagulant therapy with Warfarin who presented with acute intestinal obstruction. Computed tomography showed intramural duodenal hematoma. Treatment was conservative with correction of the coagulation parameters and observation. This case exemplifies the usefulness of conservative therapy and computed tomography in patients with acute small bowel obstruction receiving anticoagulant therapy. (author)

    Spontaneous intracranial hypotension (SIH), typically presents with orthostatic headache, low pressure on lumbar tapping, and diffuse pachymeningeal enhancement on magnetic resonance imaging. SIH is often accompanied by subdural fluid collections, which in most cases responds to conservative treatment or spinal epidural blood patch. Several authors advocate that large subdural hematoma with acute deterioration merits surgical drainage; however, few have reported complications following cranio...

  19. Liver hematoma for close abdominal traumatisms.A practice with a conservative strategy

    International Nuclear Information System (INIS)

    Liver traumatisms is a complex therapeutic problem.Within the last few years, the development of modern scanning procedures and patient control have rendered possible improvement in diagnosis and elevate follow-up of liver contusions, thus favoring a nonsurgical therapeutic approach in carefully selected patients.The purpose of this study is to evaluate selection parameters and evolutive control which are considered the efficient variables for non surgical treatment of traumatic liver hematoma.Case material was selected from among 157 patients in four hospital centers in Montevideo suffering from occluded hepatic traumatisms.Thirty five among them had hematomas and were selected, having previously been subject to CT scanning, as a basis for this study by reason of their being apt to receive primary non surgical management.Other favorable elements taken into account were their hemodynamic stability of special care units.Fibrolaparoscopy was used as an additional diagnostic and therapeutic tool.Ninety four percent of these patients were discharged without need of resorting to surgery.There were no deaths in our series.Two patients were operated due to rupture of hematoma and ensuing hemodynamic de compensation and two others had to undergo evacuation of residual intra abdominal collections.All cases were followed by CT scanning up to the complete resolution of hematoma
