Sample records for delayed hematoma caused

  1. Delayed traumatic intracranial hematoma

    International Nuclear Information System (INIS)

    CT was performed serially within 24 hours after head injury in 64 patients having Glasgow Coma Scale of 14 or less or cranial fracture shown on roentgenogram. Delayed traumatic extradural hematoma was observed within 7-12 hours after head injury in 6 cases (9.4%). This was prominent in the frontal and occipital regions (67%). Good recovery was seen in 83.3%. Delayed traumatic intracerebral hematoma was observed within 6-24 hours after head injury in 17 cases (26.6%). This higher incidence was related to contre coup injury. Conservative treatment was possible in 14 of the 17 patients (82.4%), showing good recovery in 70%. (Namekawa, K.)

    Head injury is one of the leading causes of death and disability in traumatic accidents. Post-operative contralateral epidural hematomas after surgery for acute subdural hematoma seem to be rare. In this case, expansion and spontaneous resolution of a fractural epidural hematoma contralateral to the side of acute subdural hematoma is presented. The importance of immediate post-operative computed tomography is also highlighted to detect delayed traumatic mass lesions.

    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 Introduction Postoperative spinal extradural hematomas are rare. Most of the cases that have been reported occured within 3 days of surgery. Their occurrence in a delayed form, that is, more than 72 hours after surgery, is very rare. This case is being reported to enhance awareness of delayed postoperative spinal extradural hematomas. Case presentation We report a case of acute onset dorsal spinal extradural hematoma from a paraspinal muscular arterial bleed, producing paraplegia 72 hours following surgery for excision of a spinal cord tumor at T8 level. The triggering mechanism was an episode of violent twisting movement by the patient. Fresh blood in the postoperative drain tube provided suspicion of this complication. Emergency evacuation of the clot helped in regaining normal motor and sensory function. The need to avoid straining of the paraspinal muscles in the postoperative period is emphasized. Conclusion Most cases of postoperative spinal extradural hematomas occur as a result of venous bleeding. However, an arterial source of bleeding from paraspinal muscular branches causing extradural hematoma and subsequent neurological deficit is underreported. Undue straining of paraspinal muscles in the postoperative period after major spinal surgery should be avoided for at least a few days.

  8. The importance of serial CT scanning in the diagnosis and treatment of delayed traumatic intracerebral hematoma

    International Nuclear Information System (INIS)

    Between January, 1980, and December, 1982, 99 cases of traumatic intracranial hemorrhage were admitted to our hospital. Of these cases, we analyzed 25 cases which had been submitted to initial CT scanning within 4 hours after head trauma. We found 17 cases which had no hematoma on the initial CT scan but which were found to have formed intracerebral hematoma on a repeated CT scan. We found that we could classify the delayed traumatic intracerebral hematoma into two types: Type I hematoma, which had a relatively bad outcome, and Type II hematoma which had a relatively good outcome. The neurological sign comes to deteriorate in accordance with the hematoma formation in Type I, while the neurological sign remains unchanged or takes an uphill course in accordance with hematoma formation in Type II. We recognized some differences between the two types both in the time from trauma to hematoma formation and in the serial CT findings. However, we could not differentiate the two types of hematoma on the basis only of the initial CT findings, probably because of a dynamic change in the damaged brain tissue. There seems to be no means to predict the course of delayed traumatic intracerebral hematoma; therefore, we stress the importance of strict observation both of the clinical course and of the serial CT findings in order to diagnose and to choose an appropriate course of therapy, medical or surgical.

  9. 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 Abstract Introduction Axillary artery injury in the shoulder region following blunt trauma without association with either shoulder dislocation or fracture of the humeral neck has been previously reported. Axillary artery injury might also be accompanied with brachial plexus injury. However, delayed onset of brachial plexus palsy caused by a compressive hematoma associated with axillary injury after blunt trauma in the shoulder region has been rarely reported. In previous reports, this condition only occurred in old patients with sclerotic vessels. We present a case of a young patient who suffered axillary artery injury associated with brachial plexus palsy that occurred tardily due to compressive hematoma after blunt trauma in the shoulder region without association of either shoulder dislocation or humeral neck fracture. Case presentation A 16-year-old male injured his right shoulder in a motorbike accident. On initial physical evaluation, the pulses on the radial and ulnar arteries in the affected arm were palpable. Paralysis developed later from 2 days after the injury. Functions in the right arm became significantly impaired. Angiography showed complete occlusion of the axillary artery. Magnetic resonance imaging demonstrated a mass measuring 4 × 5 cm that was suspected to be a hematoma compressing the brachial plexus in a space between the subscapular muscle and the pectoralis minor muscle. Surgery was performed on the third day after injury. In intraoperative observations, the axillary artery was occluded with thrombus along 5 cm; a subscapular artery was ruptured; the brachial plexus was compressed by the hematoma. After evacuation of the hematoma, neurolysis of the brachial plexus, and revascularization of the axillary artery, the patient had an excellent functional recovery of the affected upper limb, postoperatively. Conclusion Surgeons should be aware that axillary artery injuries may even occur in young people after severe blunt trauma in the shoulder region and can be associated with secondary brachial plexus injury due to a hematoma. For treatment in cases with progressive nervous deficit after trauma, not only reconstruction of the injured artery but also immediate evacuation of the hematoma, and exploration of the brachial plexus are necessary to avoid irreversible neurological damage.

    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.

  18. 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 hydrocephalents 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)

  19. 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)

  20. Experience with contrast-enhanced CT in delayed traumatic intracerebral hematoma

    International Nuclear Information System (INIS)

    During the four-and-a-half-year period from April, 1976, to September, 1980, out of 257 patients with severe head injuries graded 8 or less by the Glasgow Coma Scale in the Department of Neurosurgery and Critical Care Medicine of the Nippon Medical School, Tokyo, Japan, 33 cases showed the development of delayed traumatic intracerebral hematoma (DTICH) upon the serial computerized tomography (CT). Contrast-enhanced CT was performed in 20 cases of the 33 patients demonstrating DTICH. Among these, 8 cases (40%) indicated the development of DTICH in the lesions of cerebral contusion (a salt-and-pepper appearance in the initial plain CT) which showed a remarkable enhancement, sustaining the extravasation of the contrast medium into the contused brain tissue. The authors discuss the pathogenesis of DTICH and suggest that vasoparalysis in the cerebral contusion might be a factor in the development of DTICH in patients with servere head injuries. (author)

  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 t 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

    A 2 yr old spayed female mixed-breed Irish wolfhound was referred for assessment of anemia and slowly progressing abdominal distention. At the time of admission, the dog had marked anemia and thrombocytosis, a decreased serum iron concentration, and a normal coagulation profile. An ultrasound examination showed a massive fluid-filled cavitated structure in the abdominal cavity. Paracentesis of that structure yielded a large amount of hemorrhagic fluid with an iron concentration >24 times greater than the serum iron concentration, consistent with chronic sequestration of iron, leading to iron-deficiency anemia. Blood transfusions and incomplete surgical removal of the structure allowed short-term stabilization of the patient, but the dog was euthanized 17 days postsurgery for lethargy and continued abdominal distention. Histopathological evaluation of the structure was consistent with a chronic expanding hematoma. To the authors' knowledge, this is the first reported case of intra-abdominal chronic expanding hematoma in a dog. It is also unique given its features of iron-deficiency anemia caused by internal blood loss. PMID:25028435

    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.

  11. A miniseries of spontaneous intramural esophageal hematoma in hemodialysis patients: a rare cause of dysphagia.

    2014-04-01

    Intramural esophageal hematoma (IEH) is an uncommon clinical condition, with a prognosis that is essentially benign. In most cases, a predisposing factor may be seen, with the most common being the history of esophagic instrumentation, food impactions, and thrombocytopenia. We report a miniseries of 3 patients on hemodialysis, who developed IEH. All 3 of them presented with sudden onset and progressively worsening dysphagia and hematemesis. Diagnosis of IEH was established by upper gastrointestinal endoscopy. All patients were managed conservatively, and symptoms of dysphagia and chest pain improved within 6-8 days. Good resolution of hematoma was noted by repeat endoscopy within 2-3 weeks. The reported case of IEH in hemodialysis patients is rare and needs to be identified early when patients present with dysphagia, as anticoagulation during hemodialysis would possibly worsen the clinical condition, the course of which is otherwise benign.

  17. Delayed chromosomal instability caused by large deletion

    International Nuclear Information System (INIS)

    Full text: There is accumulating evidence that genomic instability, manifested by the expression of delayed phenotypes, is induced by X-irradiation but not by ultraviolet (UV) light. It is well known that ionizing radiation, such as X-rays, induces DNA double strand breaks, but UV-light mainly causes base damage like pyrimidine dimers and (6-4) photoproducts. Although the mechanism of radiation-induced genomic instability has not been thoroughly explained, it is suggested that DNA double strand breaks contribute the induction of genomic instability. We examined here whether X-ray induced gene deletion at the hprt locus induces delayed instability in chromosome X. SV40-immortalized normal human fibroblasts, GM638, were irradiated with X-rays (3, 6 Gy), and the hprt mutants were isolated in the presence of 6-thioguanine (6-TG). A 2-fold and a 60-fold increase in mutation frequency were found by 3 Gy and 6 Gy irradiation, respectively. The molecular structure of the hprt mutations was determined by multiplex polymerase chain reaction of nine exons. Approximately 60% of 3 Gy mutants lost a part or the entire hprt gene, and the other mutants showed point mutations like spontaneous mutants. All 6 Gy mutants show total gene deletion. The chromosomes of the hprt mutants were analyzed by Whole Human Chromosome X Paint FISH or Xq telomere FISH. None of the point or partial gene deletion mutants showed aberrations of X-chromosome, however total gene deletion mutants induced tranr total gene deletion mutants induced translocations and dicentrics involving chromosome X. These results suggest that large deletion caused by DNA double strand breaks destabilizes chromosome structure, which may be involved in an induction of radiation-induced genomic instability

    2006-01-01

    Full Text Available Background and Aims: Delayed traumatic hematomas and expansion of already detected hematomas are not uncommon. Only few studies are available on risk factors of expanding hematomas. A prospective study was aimed to find out risk factors associated with such traumatic lesions. Materials and Methods: Present study is based on 262 cases of intracerebral hematomas / contusions out of which 43 (16.4% hematomas expanded in size. computerized tomography (CT scan was done in all the patients at the time of admission and within 24 hours of injury. Repeat CT scan was done within 24 hours, 4 days and 7 days. Midline shift if any, prothrombin time, activated partial thromboplastin time, bleeding time, clotting time and platelet counts, Glasgow coma scale at admission and discharge and Glasgow outcome score at 6 months follow up were recorded. Results: Twenty six percent, 11.3 and 0% patients developed expanding hematoma in Glasgow Coma scale (GCS of 8 and below, 9-12 and 13-15 respectively. The chances of expanding hematomas were higher in patients with other associated hematomas (17.4% as compared to isolated hematoma (4.8% (Fisher?s exact results P =0.216. All the cases of expanding hematoma had some degree of midline shift and considerably higher proportion had presence of coagulopathy. The results of logistic regression analysis showed GCS, midline shift and coagulopathy as significant predictors for the expanding hematoma. Thirty nine patients (90.7% of the total expanding hematomas developed within 24 hours of injury. Conclusions: Enlargement of intracerebral hematomas is quite common and majority of them expand early after the injury. These lesions were common in patients with poor GCS, associated hematomas, associated coagulopathy and midline shift.

  19. The CT examination of changes in intracranial hematoma density

    International Nuclear Information System (INIS)

    The study was undertaken to assess the changes in the size and densities of intracranial hematoma by analyzing the sequential CT examination of 23 patients at Soonchunhyang College Hospital from Jul. 1980 to Aug. 1981. The results were as follows; 1. The right densities of hematoma were reduced slowly in size and density. 2. The factors influence the rate of changes were the cause of hematoma, hematoma location, age and sex of patient, and initial hematoma size. 3. The CT findings that indicate complete absorption of hematomas were normalization of mass effect, not disappearance of hematoma densities. 4. In intracerebral hematoma, the high density of hematoma reduced it's density and mass effect about 4-6 weeks duration. 5. In subdural hematoma, about 7 weeks after head trauma, the CT findings were normalized

  20. 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 Abstract Background Subperiosteal hematoma of the orbit is one of the rare lesions that cause exophthalmos after craniomaxillofacial trauma. Presently, there is no consensus for how to treat this disease. Although some reports have suggested a conservative type of therapy, others have recommended surgical treatments be done during the early stages. Case presentation This case report provides details on the clinical course of a 9-year-old girl with subperiosteal hematoma of the orbit. In this particular patient, a rare case of ipsilateral subfrontal extradural hematoma was also observed. Due to our performing the surgical intervention during the subacute stage, functional complications as well as cosmetic problems were avoided. Conclusion Our results demonstrate that surgical treatments for subperiosteal hematoma of the orbit should be delayed until it can be confirmed that a patient has no other complications. On the other hand, once it has been confirmed that the patient has no other existing problems, immediate surgical therapy with a small skin incision followed by the setting of a drain is recommended in order to achieve an early resolution and avoid complications.

    Full recovery from tetraplegia is uncommon in cervical spine injury. This has not being reported for cervical spine fracture in a patient with ankylosing spondylitis causing spinal epidural hematoma. We report on a case of cervical spine fracture in a patient with ankylosing spondylitis who came with tetraplegia. He underwent a two stage fixation and fusion. He had a complete recovery. Two hours after the operation he regained full strength in all the limbs while in the Intensive Care Unit. He went back to full employment. There are only two other reports in the literature where patients with ankylosing spondylitis and extradural hematoma who underwent treatment within 12 h and recovered completely from tetraparesis and paraplegia respectively. Patient with ankylosing spondylitis has a higher incidence of spinal fracture and extradural hematoma. Good outcome can be achieved by early diagnosis and treatment. This can ensure not only a stable spine, but also a rapid and complete recovery in a tetraplegic patient. PMID:25767586

    Morphologic examination of 3 ears from 2 dogs with aural hematomas revealed that the hematomas had developed within the pinnal cartilage. The cartilage had fractured from perichondrium to perichondrium and in some areas clefts had formed within the cartilage. Cartilage fracture could have resulted from wave motions set up in the pinna during head shaking. An explosive burst of head shaking exceeding a critical head velocity or a more gentle but sustained head shaking establishing a sinusoidal wave motion within the ear could have caused cartilage fracture.

    Full Text Available Blunt traumatic aortic injury is a life threatening condition with a mortality rate of 30%. Aortic injury commonly involves the thoracic aorta with pseudoaneurysm and intramural hematoma. Aortic intramural hematoma is a dissection without an intimal tear. Intramural aortic hematoma is an uncommon but potentially lethal aortic disease. TEE, CT, MRI and Multidetector CT can ensure a rapid and accurate diagnosis of intramural hematoma. Management of traumatic aortic intramural hematoma is not well defined in the literature. Significant intramural aortic hematoma in stable patients may remain stable on follow-up imaging. In this study we present a traumatic aortic intramural hematoma which resolved with conservative treatment in a 36 year old man who fell from a height.

    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.

    International Nuclear Information System (INIS)

    A case of calcified subdural hematoma associated with hypertensive intracerebral hemorrhage is reported. 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. (author)

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.

    Full Text Available Background. Fracture of the penis is a direct blunt trauma of the erect or semi-erect penis. It can be treated by conservative or surgical means. Retrospective analyses of conservative penile fracture treatment reveal frequent immediate and later complications. Case report. We presented a 41- year-old patient with pulsative hematoma caused by an unusual fracture of the penis. Fracture had appeared 40 days before the admittance during a sexual intercourse. The patient was treated surgically. Conclusion. Pulsative hematoma (pulsative diverticulum is a very rare, early complication of a conservatively treated penile fracture. Surgical treatment has an advantage over surgical one, which was confirmed by our case report.

    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.

  20. Spontaneous ligamentum flavum hematoma in the lumbar spine

    International Nuclear Information System (INIS)

    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.)

    Single-port laparoscopic cholecystectomy is considered as a form of natural orifice surgery with better esthetic outcomes than traditional laparoscopic cholecystectomy. It is a technically demanding procedure, and no adequately powered trial has assessed the safety of this technique. Vascular injuries are less common than bile duct injuries during this procedure, but they can be rapidly fatal. The development of a right hepatic artery pseudoaneurysm is a rare but serious complication associated with single-port laparoscopic cholecystectomy. Two weeks following a single-port laparoscopic cholecystectomy for angiocholitis, a 40-year-old male patient presented with obstructive jaundice and persistent abdominal pain. The diagnosis of compressive hematoma due to a ruptured right hepatic artery pseudoaneurysm was confirmed by computed tomography scan and angiography. It was successfully treated by selective embolization of the right hepatic artery. In our experience, endovascular management was a noninvasive and effective treatment of ruptured pseudoaneurysms.

Low intracranial pressure syndrome with brain colapse was seen in 3 cases and treated with lumbar injection of saline solution. The delay in diagnosis and operation as cause of bad outcome is stressed.

  7. Acute aortic intramural hematoma

    International Nuclear Information System (INIS)

    To evaluate the radiologic findings of acute intramural hematoma of the aorta, and the clinical follow up thereof. Among 34 cases confirmed clinically and radiologically as aortic dissection, and analysis was carried out based on 15 cases in which intramural hematoma without false lumen was demonstrated, on initial CT, 12 cases of in which follow up CT was used and five cases involving an aortogram. Elements such as the shape of the thickened aortic wall, ulcer-like intimal defects, and intimal calcification were examined. Changes in these elements were also examined on follow-up CT. DeBackey types 1 and 3 accounted for one and 14 cases, respectively. Initial precontrast CT demonstrated continuous, crescentic high attenuation areas along the wall of the descending aorta. In postcontrast scans, the crescentic areas were of relatively lower-attenuation and appeared along the aorta wall. Displaced intimal calcifications were seen in nine of fifteen patients. There was no intimal flap on all five aortogram, while aortic wall thickening and atherosclerotic change were demonstrated in four cases and in one case, respectively. Focal ulcers were seen in three cases. Ulcer-like intimal defects were demonstrated in a total of eleven cases (eight on CT, two on aortogram, and one on both). In ten of the twelve cases seen on follow up CT, the thickness of the intramural hematoma was seen to be reduced. Among the 15 cases, the operation was performed in two cases, and the remaining performed in two cases, and the remaining 13 received conservative treatment. In ten cases observed for more than twelve months, a recurrence of symptoms did not occur. Eccentric aortic wall thickening in patients who complain of acute chest pain is the result of acute aortic dissection with intramural hematoma, or a penetrating atherosclerotic ulcer of the aorta. The later may be differentiated from the former by the presence of on ulcer-like intimal defect. When both diseases are limited to the descending aorta, conservative treatment may be effective, unless patients experience persistent or recurrent chest pain, or unless intramural hematoma progresses further

    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.

  10. Postraumatic delayed loss of vision

    International Nuclear Information System (INIS)

    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

  11. 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

    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.

    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.

  17. Intramural aortic hematomas

    International Nuclear Information System (INIS)

    Intramural hematomas (IMH) are regarded as a hemorrhage into the aortic wall. In general a traumatic form can be differentiated from a spontaneous non-traumatic. There is a predisposition of IMH with arterial hypertension and mesoectodermal dysplastic syndromes. The diagnosis is established with the clinical presentation in combination with the findings of different imaging modalities. Acute and subacute discomfort associated with a tendency of collaps are considered as typical presenting complaints. A semicircular or concentric thickening of the aortic wall with the absence of blood flow or a dissection membran are typical findings in transesophageal echocardiography, computed tomography and magnetic resonance tomography. From a differential diagnostic point of view a distinction from atherosclerotic wall changes, intraluminal thrombi and inflammatory aortic diseases is essential. The IMH is considered as an early presentation of aortic dissection, put into and treated according to the Stanford classification. In the course of natural history an IMH can disappear, rupture or progress into a classic aortic dissection. (orig.)

    2008-04-01

    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.

    Full Text Available Vinodan Paramanathan, Ardalan ZolnourianQueen's Hospital NHS Foundation Trust, Burton on Trent, Staffordshire DE13 0RB, UKAbstract: Spontaneous intraorbital hematoma is an uncommon clinical entity seen in ophthalmology practice. 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

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.

  3. Delayed Hepatic Adaptation to Weaning in ACBP(-/-) Mice Is Caused by Disruption of the Epidermal Barrier

    We previously reported that mice deficient in acyl-CoA-binding protein (ACBP) display a delayed metabolic adaptation to weaning. This includes a delayed activation of the hepatic lipogenic gene program, which may result from hepatic accumulation of triacylglycerol and/or cholesteryl esters in the late suckling period. To further investigate the basis for this phenotype, we generated mice deficient in ACBP in hepatocytes (Alb-ACBP(-/-)) and keratinocytes (K14-ACBP(-/-)). Surprisingly, the delayed adaptation to weaning, including hepatic lipid accumulation, is caused by ACBP deficiency in the skin rather than in the liver. Similarly to ACBP(-/-) mice, K14-ACBP(-/-) mice exhibit an increased transepidermal water loss, and we show that the hepatic phenotype is caused specifically by the epidermal barrier defect, which leads to increased lipolysis in white adipose tissue. Our data demonstrate that an imperfect epidermal barrier leads to profound suppression of the hepatic SREBP gene program and lipid accumulation in the liver.

    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. PMID:25901264

    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.

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

    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.

    Atropa belladonna L. is a plant long known to cause poisoning. But no cases of acute subdural hematoma resulting from such poisoning have been reported so far. Care must also be taken in terms of acute pancreatitis and rhabdomyolysis in cases of such poisoning. The plant may sometimes be mistaken for the Caucasian blueberry, V. arctostaphylos L. At least one anti-cholinesterase toxidrome finding was determined in all the nine cases of belladonna poisoning in this series. No elevated creatine kinase was reported in one case with acute subdural hematoma and hyperamylasemia. PMID:21540312

    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.

    A 13-year-old cob mare was presented with exophthalmos and periocular swelling of the left eye. The diagnostic work-up included ocular ultrasound, sonographic examination through the thinned frontal bone, radiography, standing computed tomography of the skull and exploratory osteoplastic surgery. Histopathology was consistent with an organized hematoma. An intradiploic hematoma of the frontal bone was diagnosed 5 years after head trauma, with progressive expansion and deformation of the skull resulting in exophthalmos. Exophthalmos with facial bone deformation was the only clinical finding of intradiploic hematoma. Standing computed tomography (CT) aided the diagnosis to differentiate intradiploic hematoma from other, more common causes of facial bone distortion associated with paranasal sinus diseases. Intradiploic hematoma of possible traumatic origin is a differential diagnosis for sinonasal disease and exophthalmos in the horse. PMID:23953510

    Delays in diagnosis and treatment are widely considered to be threats to outpatient safety. However, few studies have identified and described what factors contribute to delays that might result in patient harm in the outpatient setting. We analyzed 111 root cause analysis reports that investigated such delays and were submitted to the Veterans Affairs National Center for Patient Safety in the period 2005-12. The most common contributing factors noted in the reports included coordination problems resulting from inadequate follow-up planning, delayed scheduling for unspecified reasons, inadequate tracking of test results, and the absence of a system to track patients in need of short-term follow-up. Other contributing factors were team-level decision-making problems resulting from miscommunication of urgency between providers and providers' lack of awareness of or knowledge about a patient's situation; and communication failures among providers, patients, and other health care team members. Our findings suggest that to support care goals in the Affordable Care Act and the National Quality Strategy, even relatively sophisticated electronic health record systems will require enhancements. At the same time, policy initiatives should support programs to implement, and perhaps reward the use of, more rigorous interprofessional teamwork principles to improve outpatient communication and coordination.

    Cardiomyopathy is a major cause of morbidity and mortality. Ventricular conduction delay, as shown by prolonged deflections in the electrocardiogram caused by delayed ventricular contraction (wide QRS complex), is a common feature of cardiomyopathy and is associated with a poor prognosis. Although the G(i)-signaling pathway is up-regulated in certain cardiomyopathies, previous studies suggested this up-regulation was compensatory rather than a potential cause of the disease. Using the tetracycline transactivator system and a modified G(i)-coupled receptor (Ro1), we provide evidence that increased G(i) signaling in mice can result in a lethal cardiomyopathy associated with a wide QRS complex arrhythmia. Induced expression of Ro1 in adult mice resulted in a >90% mortality rate at 16 wk, whereas suppression of Ro1 expression after 8 wk protected mice from further mortality and allowed partial improvement in systolic function. Results of DNA-array analysis of over 6,000 genes from hearts expressing Ro1 are consistent with hyperactive G(i) signaling. DNA-array analysis also identified known markers of cardiomyopathy and hundreds of previously unknown potential diagnostic markers and therapeutic targets for this syndrome. Our system allows cardiomyopathy to be induced and reversed in adult mice, providing an unprecedented opportunity to dissect the role of G(i) signaling in causing cardiac pathology. PMID:10781088

    How stable synchrony in neuronal networks is sustained in the presence of conduction delays is an open question. The Dynamic Clamp was used to measure phase resetting curves (PRCs) for entorhinal cortical cells, and then to construct networks of two such neurons. PRCs were in general Type I (all advances or all delays) or weakly type II with a small region at early phases with the opposite type of resetting. We used previously developed theoretical methods based on PRCs under the assumption of pulsatile coupling to predict the delays that synchronize these hybrid circuits. For excitatory coupling, synchrony was predicted and observed only with no delay and for delays greater than half a network period that cause each neuron to receive an input late in its firing cycle and almost immediately fire an action potential. Synchronization for these long delays was surprisingly tight and robust to the noise and heterogeneity inherent in a biological system. In contrast to excitatory coupling, inhibitory coupling led to antiphase for no delay, very short delays and delays close to a network period, but to near-synchrony for a wide range of relatively short delays. PRC-based methods show that conduction delays can stabilize synchrony in several ways, including neutralizing a discontinuity introduced by strong inhibition, favoring synchrony in the case of noisy bistability, and avoiding an initial destabilizing region of a weakly type II PRC. PRCs can identify optimal conduction delays favoring synchronization at a given frequency, and also predict robustness to noise and heterogeneity. PMID:22241969

From a total number of 24 902 deliveries, there were 82 retroplacental hematomas with 87 products (per 5 twin pregnancies which yields an incidence of 0.33 %. Statistical percentage methods were used, as well as the x² test where 0.01 to 0.05, and the finding of arithmetic mean which allowed the study of variables by means of statistical tables. The influence of this entity in the indicators of perinatal mortality of this center was demonstrated, where retroplacental hematoma in its more severe clinical form was found to be the main cause of the most frequent and severe complications. Its effect on mortality, low birth weight, and on the index of low Apgar score is also reported.

  19. 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.

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.

    Spontaneous spinal epidural hematomas (SSEH) are heralded by spinal pain and progressive cord compression syndromes which may lead to permanent neurological disability or death if emergent neurosurgical intervention is delayed. It therefore must be considered early in the differential diagnosis of acute spinal cord compression syndrome. A case of spontaneous spinal epidural hematoma presenting as an acute myelopathy in a clarinet player who chronically used a nonsteroidal anti-inflammatory medication is presented. The case was remarkable for the rare complete spontaneous resolution of neurological function. Approximately 250 cases of SSEH have been reported in the medical literature, although only a handful of these patients have recovered spontaneously. This is the sixth report of such an event. The etiologies, contributing factors, disease progression, and treatment recommendations are discussed. PMID:8768163

    Full Text Available Construction projects in developing countries have the priority among other projects as they are considered safe investments in an unpredictable market. Due to this prioritization, it has become increasingly important that such projects are managed in accordance with internationally accepted management best practice. Project managers of construction projects in developing countries face difficulties in effectively monitoring the progress of projects they are responsible for due to many variables. The purpose of this study is to investigate the causes of delays in the construction projects that were covered in the considered literature and conduct qualitative research to investigate their relevance by interviewing project managers of actual projects in Lebanon. Based on the literature review and from the recommendations recorded during interviews, the researcher aims to create a set of guidelines that will improve the manner in which project managers can adapt to, discover and deal with project delays. These guidelines can be utilized as an early warning system concerning delays in construction projects.

    The pathogenesis of canine and feline aural hematoma (AH) was investigated. Clinical observations, selected experimental procedures, and clinicopathologic examinations were done on 40 dogs and 20 cats affected with AH. Eighteen healthy dogs and 14 healthy cats were used as the controls. The results of this investigation provide a valid basis for questioning the conventionally held view that AH is caused by trauma and for postulating that the actual cause is immune mediated.

    2008-01-01

    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.

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.

    Mitochondrial fusion and fission is a dynamic process critical for the maintenance of mitochondrial function and cell viability. During excitotoxicity neuronal mitochondria are fragmented, but the mechanism underlying this process is poorly understood. Here, we show that Mfn2 is the only member of the mitochondrial fusion/fission machinery whose expression is reduced in in vitro and in vivo models of excitotoxicity. Whereas in cortical primary cultures, Drp1 recruitment to mitochondria plays a primordial role in mitochondrial fragmentation in an early phase that can be reversed once the insult has ceased, Mfn2 downregulation intervenes in a delayed mitochondrial fragmentation phase that progresses even when the insult has ceased. Downregulation of Mfn2 causes mitochondrial dysfunction, altered calcium homeostasis, and enhanced Bax translocation to mitochondria, resulting in delayed neuronal death. We found that transcription factor MEF2 regulates basal Mfn2 expression in neurons and that excitotoxicity-dependent degradation of MEF2 causes Mfn2 downregulation. Thus, Mfn2 reduction is a late event in excitotoxicity and its targeting may help to reduce excitotoxic damage and increase the currently short therapeutic window in stroke. PMID:25147362

    We present two variant cases of spontaneous rectus sheath hematoma (SRSH). A 71-year-old woman presented with ST elevation myocardial infarction and was found to have multivessel coronary artery disease. She was treated with aspirin, clopidogrel, eptifibatide, and heparin. Heparin was continued while preoperative workup for coronary artery bypass grafting was done. She developed a large 20x10 cm actively bleeding SRSH while on heparin. It was surgically evacuated. The second case represents an atypical cause of SRSH. A 64-year-old woman with Wegener's Granulomatosis presented with anemia and abdominal pain. Abdominal CT showed a large 22 cm SRSH without active bleeding that was treated conservatively. Both patients did well on follow-up. The incidence of SRSH is likely to increase in the coming years with the increasing use of antithrombotic agents for many disease processes. Clinicians should be aware of typical and atypical presentations of SRSH and its variant management options. PMID:25369220

    Soft-tissue sarcomas are rare and often confused for more common and benign disorders during diagnosis. Chronic expanding hematomas are particularly difficult to distinguish from soft-tissue malignancy. We describe the case of a morbidly obese patient with a chronic expanding hematoma in the distal posterior thigh whose definitive treatment was delayed 6 months because of her pregnancy status and inability to lie prone for open biopsy.

    Full Text Available The Retro Placental Hematoma (RPH or placental abruption untimely normally inserted paroxysmal is an accident that threatens maternal and fetal prognosis. It is a major emergency obstetric pathology and remains the second leading cause of maternal mortality after postpartum haemorrhage. It is actually very difficult to have an accurate evaluation the frequency of the HRP because it requires a complete table including Pathologists; or simple macroscopic or microscopic findings; or purely clinical diagnosis for some. Its occurrence requires appropriate resuscitation and adapted care to improve the prognosis. We report our study of 49 cases the HRP hospitalized in Obstetrics and Gynecology of Instruction Military Hospital Mohamed V in Rabat, diagnosed on a suggestive clinical picture and the presence of hematoma after examining the issue. This is a descriptive and comparative retrospective study over a period of one year. This study compared two groups: with HRP feotale death in utero and HRP without fetal death in utero. This study aims to evaluate neonatal mortality and maternal morbidity related to RPH and therapeutic modalities. This pathology formerly known pathology multiparous tends to reach more and more heifer. The important blood loss and delay the expulsion worse prognosis causing severe maternal morbidity hence the need to expand the indications for cesarean of retro placental hematoma regardless of the fetal state. Our study aims to contribute to reduce mortality and morbidity Fetomaternal by improving our work is stepping up efforts for a rapid decision-making, and we must educate what especially pregnant women of the risk factors to see from the beginning of symptoms. The pregnancy monitoring, early diagnosis of RPH, an obstetrical treatment adequate, and a resuscitation well driving can improve the prognosis of this disease.

  13. Bannayan-Riley-Ruvalcaba syndrome: a cause of extreme macrocephaly and neurodevelopmental delay.

    LENUS (Irish Health Repository)

    Lynch, N E

    2012-02-01

    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.

    Arteriovenous malformations are the most common cause of spontaneous intracerebral hemorrhages in older children. Intracerebral hematoma can cause serious lasting neurologic, cognitive, and language deficits, or even possible death. We present the case of a 16-year-old boy who had language impairments after suffering a large hemorrhagic stroke in the left temporoparietal region. All language components, verbal and nonverbal communication, reading, and writing, were found to be affected. These impairments were expected as they are characteristic of the location of the hematoma. After a year of speech language rehabilitation, there was an almost complete recovery of language skills. Quick diagnosis and adequate therapeutic interventions are important to diminish the influence of intracerebral hemorrhage on cognitive and language functions in children. PMID:24532808

  15. Solitary pulmonary nodule by pulmonary hematoma under warfarin therapy

    International Nuclear Information System (INIS)

    Pulmonary hematoma is a rare cause of a pulmonary nodule. Mostly it results from penetrating or blunt chest injuries. The case of a patient is reported, whose chest X-ray showed a pulmonary nodule suspected of malignancy. This patient was maintained permanently on anticoagulants (warfarin derivates) after cardiac valve replacement with a prosthesis. A definite diagnosis could not be established by non-invasive methods. A needle biopsy of the lung was impracticable because of the location of the pulmonary lesion; an exploratory thoracotomy could not be carried out due to a general indication of nonoperability. Control examinations showed that the pulmonary nodule had vanished completely within four months. In consideration of the patient's clinical situation it can be concluded that the pulmonary lesion was caused by a hematoma of the lung. (orig.)

  16. An Experimental Study on the Effect of Subperiosteal Transplantation of Fracture Site Hematoma: Focus on the Scintigraphic Detection

    International Nuclear Information System (INIS)

    It has been reported that hematoma is one of the most crucial factors in fracture healing since callus formation is disturbed by washing out the hematoma near a fracture site. However, it is not clear why the hematoma is important and how it plays a role during the fracture healing. In order to investigate the role of hematoma in the process of fracture healing, the osteogenic potential by subperiosteal transplantation have been studied. Experimental fractures by operation were made at the mid-shaft of the tibia in New Zealand white rabbits. Removal of hematoma at the fracture site was done after 2 and 3 days from experimental fracture, and the removed hematoma was transplanted into the subperiosteal area at the mid-shaft of the ulna of each rabbit. As control groups, we have performed 3 different procedures 1) the hematoma was transplanted into the muscular layers at the thigh and forearm; 2) autologous blood clots were transplanted into the subperiosteal area of the ulna; and 3) sham operation without a transplantation into the subperiosteal area. After transplantation, serial bone scintigraphy and simple radiography were performed at 4 days, 1 week, and 2 weeks to detect an abnormality. The results of bone scintigraphy were positive in 5 of 6 experimental group. However, all in three control groups were negative. Histological observation of the positive bone revealed new bone formation with trabeculation. These results suggest the hematoma in fracture site has osteest the hematoma in fracture site has osteogenic potential in the subperiosteal area which can be demonstrable by bone scintigraphy and histologic findings. Therefore, it is considered that hematoma of the fracture site plays an important role in the process of fracture healing. Further biochemical investigation using various experimental models is mandatory to apply this preliminary result to the treatment of clinical delayed union or nonunion.

  18. 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.

    Full Text Available On-time completion and conformity with assigned costs of every project or plan is one of the most important factors in success of that project or plan. No completion or overrun cost leads to not meeting the employer`s requirements need or goals of the plan or the project. This issue is of greater importance in large and national projects in which the period of execution is long even in normal conditions and takes more than 6 years averagely. Dam construction projects are of especial importance regarding on-time completion and assigned funds because of their importance in operation size, great investment, complicated nature and many uncertainties in them like underground conditions, natural disasters and high cost of construction. So, inspection, identification and evaluation of causes of cost and time overrun and representations of solutions for obviating them have great benefits for economy of the country. Besides in most cases precise and sufficient information is not available for this purpose and opinions of experts and professionals in this project (in fuzzy theory framework should be used. In this study, in addition to brief review of studies related to the issue of delays, fuzzy theory and method of using it is explained and real value of cost and time overrun in some dams of Iran is calculated and subsequently, fuzzy identification and evaluation of causes and cost and time overrun in these projects are dealt with.

Abstract in english BACKGROUND AND OBJECTIVES: The development of a retropharyngeal hematoma following a blunt trauma is a rare occurrence. However, a spaceoccupying lesion in this area can be life-threatening and requires rapid assessment and treatment. This is clinically important because of the close proximity of th [...] e retropharyngeal space to the upper airway. Any swelling in the the posterior pharyngeal space may prompt it to bulge anteriorly into the airway and cause its obstruction. CASE REPORT: A 86-year-old woman fell from a height of 1.5 m and hit her neck on stairs and was admitted to our trauma department. A computerized tomography scan and a lateral neck x-ray to observe the soft tissue revealed a large retropharyngeal mass extending from the base of the skull down to the level of the lung. The patient was kept under observation and the hematoma reduced spontaneously in the following seven days although the patient died on the tenth day from pulmonary infection. The report emphasizes that early drainage of a retropharyngeal hematoma should be considered in similar cases. Although rarely encountered, retropharyngeal hematoma is a problem that can be faced in an emergency department.

  1. Spontaneous cervical epidural hematoma: Report of a case managed conservatively

    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.

    Spontaneous rupture of the kidney involves either the collecting system or parenchyma, the latter being associated with a subcapsular or perirenal hematoma. A review was made of 78 cases of spontaneous parenchymal rupture with perirenal hematoma, including 4 of our own. One of these cases is the first description of spontaneous rupture of the kidney secondary to renal vein thrombosis. The patients are usually in the fourth decade of life and present with an acute onset of flank pain, a tender mass and commonly symptoms and signs of shock. Hematuria is often present and generally urography reveals a mass, distorted collecting system and/or non-visualization of the kidney. Tumors are the most common cause followed by vascular diseases, infection, nephritis and blood dyscrasias. Nephrectomy when possible should be performed expeditiously since conservative therapy is uniformly unsuccessful. PMID:1159905

    Full Text Available Spontaneous hematomas are rare and most occur secondary to hematologic disorders or during anticoagulant therapy. Most spontaneous hematomas occur above the sigmoid colon, and rarely in the rectum. Herein we present the case of a patient with a spontaneous perforating hematoma of the rectum who presented with severe abdominal pain after a bloody stool. The hemoglobin level decreased by 33 g/L within 20 h. An abdominal sonogram showed a hydrops in the lower abdomen with a maximum depth of 7.0 cm. A hematoma, 8 cm × 6 cm × 5 cm in size, was noted intra-operatively in the rectosigmoid junction, with a 1.5-cm perforation in the hematoma and active hemorrhage. Thus, a partial rectectomy and sigmoidostomy were performed. Three months later, a second operative procedure to re-establish intestinal continuity was performed. The patient is in good condition 12 mo after the last surgery. In addition to this case, the causes of spontaneous perforating hematomas and the treatment are discussed.

    Craniosynostosis and supernumerary teeth most often occur as isolated developmental anomalies, but they are also separately manifested in several malformation syndromes. Here, we describe a human syndrome featuring craniosynostosis, maxillary hypoplasia, delayed tooth eruption, and supernumerary teeth. We performed homozygosity mapping in three unrelated consanguineous Pakistani families and localized the syndrome to a region in chromosome 9. Mutational analysis of candidate genes in the region revealed that all affected children harbored homozygous missense mutations (c.662C>G [p.Pro221Arg], c.734C>G [p.Ser245Cys], or c.886C>T [p.Arg296Trp]) in IL11RA (encoding interleukin 11 receptor, alpha) on chromosome 9p13.3. In addition, a homozygous nonsense mutation, c.475C>T (p.Gln159X), and a homozygous duplication, c.916_924dup (p.Thr306_Ser308dup), were observed in two north European families. In cell-transfection experiments, the p.Arg296Trp mutation rendered the receptor unable to mediate the IL11 signal, indicating that the mutation causes loss of IL11RA function. We also observed disturbed cranial growth and suture activity in the Il11ra null mutant mice, in which reduced size and remodeling of limb bones has been previously described. We conclude that IL11 signaling is essential for the normal development of craniofacial bones and teeth and that its function is to restrict suture fusion and tooth number. The results open up the possibility of modulation of IL11 signaling for the treatment of craniosynostosis.

  9. Traumatic hematomas in deep middle portion of the cerebrum case report

    International Nuclear Information System (INIS)

    Recently we have encountered three cases of small traumatic hematoma in deep middle portion of the cerebrum. Patient 1: A 55-year-old male was admitted to our hospital 2-days after the traffic accident. CTscan showed small hematoma around septum pellucidi and fornix and in the posterior horn of left lateral ventricle. Patient 2: A 54-year-old male was admitted to our hospital a day after the head injury. CTscan showed hematoma in the supraventral portion of the third ventricle. Patient 3: A 27-year-old male was admitted to our hospital a day after the head injury. CTscan showed hematoma around quadrigeminal cistern and midbrain. Three cases reported here are traumatic hematomas without mass effect, which were pointed out only by autopsy. On traumatic hematoma in the deep middle portion of the brain we have only a few reports. On the mechanism of this bleeding Lindenberg and Kohno reported that the bleeding is caused by outward bending of the skull in injury. Lindenberg et al insisted that when traumatic force goes through corpus callosum over stretching of corpus callosum caused bleeding and that shearing force can damage septum pellucidi and fornix. Although these small hematomas are absorbed gradually functional prognosis is poor. Especially Korsakov syndrome and left hemiparesis in patient 1 shows no sign of recovery. In patient 2 and patient 3 decreased mental activity and hemiparesis have continued. Treatment of these cases cannot be surgical, as far as severe bres cannot be surgical, as far as severe brain edema does not appeared. (author)

    Full Text Available Subperiosteal Hematoma orbit is an uncommon disorder which may occur following injury to orbit. Ofcourse there are other causes that cause this condition as well. This condition has been reported in young adults. This case report discusses a patient who developed subperiosteal hematoma following trivial injury to orbit. Since this condition had occurred following trivial injury to orbit diagnosis was not made pre operatively. It was discovered only on the table. A high index of suspicion and an accurate history is necessary to identify this condition. This case is being reported not only for its rarity but also to stress the importance of eliciting accurate history.

    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, in...

    The delay involved in operating on emergency general surgical patients is often excessive. This problem has been examined prospectively in a district general hospital with a catchment population of 450,000. Over a 16-week period, the details of 204 consecutive general surgical emergency operations were recorded and analysed. Following essential resuscitation, the median delay in operating on emergency general surgical patients was 3 h. Eighty-eight patients had to wait in excess of 1 h, with ...

  13. House agrees with president that delay in international family planning aid causes harm.

    Science.gov (United States)

    1997-02-14

    On February 13, the U.S. House of Representatives approved (220-209) HJR 36, which would release funds for the overseas family planning program administered by the United States Agency for International Development (USAID) on March 1. Under the initial spending measure approved as part of the omnibus appropriations package passed in September 1996, funds would have been released on July 1 (9 months into the budget year), unless President Clinton determined the delay was having a "negative impact on the proper functioning of the family planning assistance program". On January 31, President Clinton determined that the budget freeze of these funds would "cause serious, irreversible, and avoidable harm". The vote on HJR 36 will not affect the stipulation that the money for the year must be released in month-by-month installments. The president's decision was based on a report by USAID which showed that withholding funds would have the following results: 50 million condoms, 4.8 million cycles of birth control pills, and 500,000 IUDs would not be provided; and 17 of 95 USAID-funded family planning programs in 50 countries might have to be closed. The Foreign Operations funding bill for fiscal year 1996 had already decreased funds for family planning by 35% from the previous year to $356 million; a compromise between the House and Senate increased this amount to $385 million for fiscal year 1997. The House, on February 13, also passed HR 581 (231-194), which would reinstate a policy of Presidents Reagan and Bush: any organization receiving U.S. family planning aid would have to certify that it did not provide abortions, even if other sources paid for them, except in cases of life endangerment, rape, or incest. Such organizations must also certify that they would not violate or lobby to change abortion laws, except in opposition to coercive abortion or involuntary sterilization. Passage of this bill, which was introduced by Representative Christopher Smith (R-NJ) and which would remove the month-by-month distribution of aid, is considered to be symbolic; one objection would keep it from a vote in the Senate.

  14. 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 treclinical 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

    2015-01-01

    Nasal septal hematoma is a collection of blood between the cartilage or bone and mucoperichondrium or mucoperiosteum of the nose. This condition requires immediate surgical drainage to prevent complications. All patients need nasal packing postoperatively to prevent recurrence. This causes a lot of discomforts due to mouth breathing more in infants who are obligatory nose breathers. They can go for cyanosis in the postoperative period. Here, we discuss the case report of an infant who had tubular nasal pack with endotracheal tube postoperatively to maintain the patency of nose.

    We study the propagation of exciton-polaritons through bulk ZnO using time-resolved photoluminescence (PL) complemented by time-of-flight measurements of laser pulses. When the photon energy approaches donor bound exciton resonances, substantial time delays in PL light propagation are observed which reach up to 210?ps for a 0.55?mm thick crystal. By comparing results from time-of-flight measurements performed using PL light and laser pulses, the observed delay is shown to be due to the fo...

  17. Self-Administered Cocaine Causes Long-Lasting Increases in Impulsive Choice in a Delay Discounting Task

    2010-01-01

    Cocaine use is associated with high levels of impulsive choice (preference for immediate over delayed rewards), but it is not clear whether cocaine use causes elevated impulsive choice, or whether elevated impulsive choice is solely a predisposing factor for cocaine use. This study examined the effects of prior cocaine self-administration on rats performing a delay discounting task commonly used to measure impulsive choice. Male Long-Evans rats were implanted with intravenous catheters, and following recovery, were trained to self-administer 30 mg/kg/day cocaine HCl (approx. 0.5 mg/kg/infusion) for 14 consecutive days (a control group received yoked intravenous saline infusions). Following three weeks of withdrawal, all rats were food-restricted and began training on the delay discounting task in standard operant chambers. On each trial, rats were given a choice between two levers. A press on one lever delivered a small food reward immediately, and a press on the other delivered a large food reward after a variable delay period. Rats that self-administered cocaine displayed greater impulsive choice (enhanced preference for the small immediate over the large delayed reward, as reflected by shorter indifference points) compared to controls, but were no different from controls on a “probabilistic discounting” task in which they chose between small certain and large uncertain rewards. These data suggest that self-administered cocaine can cause lasting elevations in impulsive choice, and that the high levels of impulsive choice observed in human cocaine users may be due in part to long-term effects of cocaine on brain function.

  18. A case of acoustic neurinoma associated with chronic subdural hematoma after gamma knife radiosurgery

    International Nuclear Information System (INIS)

    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)

    2009-11-01

    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.

  20. On the pathogenesis of traumatic intracerebral hematoma with a sequential study of computerized tomography

    International Nuclear Information System (INIS)

    A sequential study with computerized tomography (CT scan) of two cases of traumatic intracerebral hematoma is reported. Case 1 was a 69-year-old man who had a head injury. The initial CT scan, taken 1 hour after his injury, showed a left temporal salt-and-pepper appearance, which proved to be a cerebral contusion. The CT scan 4.5 hours after his injury showed a left temporal high density area instead. An operation was performed, and a massive intracerebral hematoma was observed. Case 2 was a 61-year-old man who was also admitted because of a head injury. The initial CT scan, taken 1 hour after his injury, revealed several bifrontal intracerebral hemorrhagic spots in the low-density areas, suggesting contusion. A secondary CT scan (23 hours) demonstrated that the traumatic intracerebral hematoma had developed into a posttraumatic cerebral contusion. The operation disclosed a hematoma surrounded by contusion. These cases prove that traumatic intracerebral hematoma is often caused by cerebral contusion. (author)

  1. 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.)

  3. CT-guided stereotactic evacuation of hypertensive intracerebral hematomas

    International Nuclear Information System (INIS)

    Computerized tomography (CT) is now effective not only for definite diagnosis and location of intracerebral hematomas but also for coordination of the center of a hematoma. CT-guided stereotactic evacuation of hypertensive intracerebral hematoma was performed in 51 cases: 34 of basal ganglionic hematoma with or without ventricular perforation, 11 of subcortical hematoma, 3 of thalamic hematoma and 3 of cerebellar hematoma. Three dimensional CT images or biplane CT images were taken to determine the coordinates of the target point, which was the center of the hematoma. Then, a silicon tube (O.D. 3.5 phi, I.D. 2.1 phi) was inserted into the center of the hematoma through a burr-hole under local anesthesia, and the liquid or solid hematoma was aspirated as completely as possible with a syringe. Urokinase (6,000 I.U./5 ml saline) was administered through this silicon tube every 6 or 12 hours for several days until the hematoma had drained out competely. The silicon tube was taken out when repeated CT scanning revealed no hematoma. The results of clinical follow-ups indicated that this procedure is as good as, or rather better than conventional microsurgery with evacuation of hematoma under direct vision. Moreover this CT-guided stereotactic approach for evacuation of the hematoma has the following advantages: 1) the procedure is simple and safe, 2) operation can be performed under local anesthesia, and 3) the hematoma is drained out completely with the aid of urokinase. Tut completely with the aid of urokinase. This surgery seems indicated as an emergency treatment for high-age or high risk patients and also as a routine surgery for intracerebral hematomas in patients showing no herination signs. (author)

    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.

    A 70-year-old woman was performed percutaneous coronary intervention at the stenotic lesion of the 1st diagonal branch. Soon after stenting, cardiac tamponade occurred and emergent cardiac surgery was performed. A large epicardial hematoma was observed in the antero-lateral wall that was compressing the distal diagonal branch. The patient died of multi-organ failure 3 days after surgery. An autopsy of her heart revealed an extensive intramural hematoma in the left ventricular wall. There was no evidence of perforation of the stented lesion. The suspected cause was neither coronary perforation nor coronary rupture of target lesion. PMID:18922392

    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.

  10. The repeat CT-findings of the contusional hematoma

    International Nuclear Information System (INIS)

    Twenty-seven cases of traumatic intracerebral hematoma were treated from 1977 to 1979. The intracerebral hematomas are classified into three groups: central type, hematoma within contusional area and contusional hematoma, according to the CT findings and the clinical course. Fourteen of these cases are diagnosed as contusional hematoma which show a normal CT scan, subarachnoidal hemorrhage, subdural hematoma and epidural hematoma without any kind of intracerebral high density in the initial CT scan performed within 6 hours after injury. Ten of the cases were found during conservative treatment; in 2 cases, hematomas were revealed within 24 hours; in 2 more cases within 48 hours, and in 6 cases, within 3 - 5 days following injury. In the other 4 cases, hematoma occurred 1 - 2 days following the emergency evacuation of a subdural hematoma and decompressive craniectomy. Based on the clinical experience outlined above, it is our current practice in diagnosing patients with contusional hematoma to perform repeat CT scanning within 5 - 6 days after injury whenever isodensity or subarachnoidal hemorrhage with a shift in the midline structure is observed in an initial CT scan within 6 hours or whenever an evacuation of the subdural hematoma with decompressive craniectomy is performed.

    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. PMID:23162198

    International Nuclear Information System (INIS)

    The frequency of hematoma in the posterior fossa was higher in these cases than in past reports, suggesting that CT facilitated the diagnosis. The most important factor exacerbating the prognosis was intradural lesions. The prognosis of patients with extradural hematoma alone was satisfactory, irrespective of its clinical severity. The operative prognosis of the patients depended greatly on the earliness of initial treament, and the reduced time in diagnosing because of the advent of CT was thought to be one of the great factors for the improved operative prognosis.

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. This case illustrates the crucial role of a recipient's platelets in the development of TRALI.Keywords: delayed TRALI syndrome, recurrence, anti-platelet antibody

    Full Text Available A rectus sheath hematoma occurs an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric arteries or their branches or rectus muscle tear. The choice of effective treatment of rectus sheath hematoma and the decision to admit the patient to hospital depends on the degree of haemodynamic compromise, coagulation status as well as the type of the hematoma on abdominopelvic computerized tomography scans. In this article, we report a case of spontaneous rectus sheath hematoma presenting with acute abdominal pain associated with a palpable abdominal wall mass. Furthermore, diagnosis, classification, and management of rectus sheath hematoma in the emergency room are discussed.

    We describe a rare case of delayed surgery for blunt ascending aortic injury. A 77-year-old man was injured in a traffic accident. He lost consciousness and suffered severe blunt trauma to the chest. Computed tomography showed multiple head and chest injuries and acute Stanford type A aortic dissection. The operation was postponed because he was hemodynamically stable and his risk of surgical death was increased due to his other injuries. Serial computed tomography showed growth of the aortic lesion, and aortic surgery was successfully performed 11 months after admission to the hospital. The postoperative course was uneventful.

    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.

    Although intracranial hematoma detection only requires the continuous wave technique of near infrared spectroscopy (NIRS), previous studies have shown that there are still some problems in obtaining very accurate, reliable hematoma detection. Several of the most important limitations of NIR technology for hematoma detection such as the dynamic range of detection, hair absorption, optical contact, layered structure of the head, and depth of detection are reported in this article. A pulsed light source of variable intensity was designed and studied in order to overcome hair absorption and to increase the dynamic range and depth of detection. An adaptive elastic optical probe was made to improve the optical contact and decrease contact noise. A new microcontroller operated portable hematoma detector was developed. Due to the layered structure of the human head, simulation on a layered medium was analyzed experimentally. Model inhomogeneity tests and animal hematoma tests showed the effectiveness of the improved hematoma detector for intracranial hematoma detection. PMID:10938785

    About 3-5% of pituitary tumors occur in pediatric patients, often showing a considerable severity during childhood and puberty and major difficulties in their therapeutic management. As far as macroprolactinomas are concerned, surgery is often not resolutive, so that the need for postoperative treatment, consisting of either radiotherapy or bromocriptine, is the rule for tumors with extrasellar extension. In the present manuscript we report two cases of macroprolactinomas in adolescent patients suffering from delayed puberty, short stature and ocular symptoms together with hormonal levels indicating the presence of hypopituitarism. In both patients bromocriptine therapy showed a particular efficacy both in controlling tumor size and growth and in reducing clinical signs and symptoms. We conclude proposing DA-therapy as a first line of management in adolescents affected by macroprolactinomas, even in the presence of neurological symptoms. PMID:8968149

    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.

  4. 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.

    Abstract Objectives. We evaluated the incidence and predisposing factors of groin hematomas after electrophysiological (EP) procedures. Design. Prospective, observational study, enrolling consecutive patients after EP procedures (Atrial fibrillation: n = 151; Supraventricular tachycardia/Diagnostic EP: n = 82; Ventricular tachycardia: n = 18). Patients underwent manual compression for 10 min and 3 h post procedural bed rest. AF ablations were performed with INR 2-3, ACT > 300, and no protamine sulfate. Adhesive pressure dressings (APDs) were used if sheath size ? 10F; procedural time > 120 min; and BMI > 30. Patient-reported hematomas were recorded by a telephone follow-up after 2 weeks. Results. Hematoma developed immediately in 26 patients (10%) and after 14 days significant hematoma was reported in 68 patients (27%). Regression analysis on sex, age, BMI 25, ACT 300, use of APD, sheath size and number, and complicated venous access was not associated with hematoma, either immediately after the procedure or after 14 days. Any hematoma presenting immediately after procedures was associated with patient-reported hematomas after 14 days, odds ratio 18.7 (CI 95%: 5.00-69.8; P < 0.001). Conclusions. Any hematoma immediately after EP procedures was the sole predictor of patient-reported hematoma after 2 weeks. Initiatives to prevent groin hematoma should focus on the procedure itself as well as post-procedural care.

  7. 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)

  8. CT guided stereotactic evacuation of hypertensive and traumatic intracerebral hematomas

    International Nuclear Information System (INIS)

    Recent advancement of CT system provides not only definite diagnosis and location of intracerebral hematoma but also coordinates of the center of the hematoma. Trials of stereotactic evacuation of the hematoma have been reported by some authors in the cases of subacute or chronic stages of hypertensive intracerebral hemorrhage. In this series, similar surgery has been performed in 33 cases of hypertensive intracerebral hematoma including 22 cases in acute stage, and 2 cases of traumatic hematoma. Clinical outcomes were investigated and the results were considered to be equivalent or rather better in the conventional microsurgery with evacuation of hematoma under direct vision. However, there still remained controversial problems in the cases of threatened herniation signs, because in these cases regular surgery with total evacuation of the hematoma at one time might have been preferable. The benefits of this CT guided stereotactic approach for the evacuation of the hematoma were thought to be as follow: 1) the procedure is simple and safe, 2) operation is readily performed under local anesthesia, and 3) the hematoma was drained out totally by means of urokinase activity. It is our impression that this surgery not only is indicated as emergency treatment for the patients of high-age or in high risk, but also can institute as a routine surgery for the intracerebral hematomas in patients showing no herniation sign.

  9. Spinal Epidural Hematoma After Thrombolysis for Deep Vein Thrombosis with Subsequent Pulmonary Thromboembolism: A Case Report

    International Nuclear Information System (INIS)

    A 38-year-old male was initially admitted for left leg swelling. He was diagnosed as having deep vein thrombosis (DVT) in the left leg and a pulmonary thromboembolism by contrast-enhanced chest computed tomography (CT) with delayed lower extremity CT. The DVT was treated by thrombolysis and a venous stent. Four hours later, he complained of severe back pain and a sensation of separation of his body and lower extremities; he experienced paraplegia early in the morning of the following day. Magnetic resonance imaging showed a spinal epidural hematoma between T11 and L2, which decompressed following surgery. We, therefore, report a case of a spinal epidural hematoma after thrombolysis in a case of DVT with a pulmonary thromboembolism

    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.

    We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    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.

    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

  3. Capsular and thalamic infarction caused by tentorial herniation subsequent to head trauma

    International Nuclear Information System (INIS)

    Five patients (4 male and 1 female) were observed to have capsular and thalamic infarction ascribed to descending transtentorial herniation (DTH) caused by head injury. A lucid interval immediately after the trauma and the presence of an epidural hematoma (EDH) characterized all five case. The low attenuation implicated the perforating arteries, that is the anterior thalamoperforating and anterior choroidal arteries, suggesting infarcted regions caused by occlusion of these arteries. Findings in the present study suggest that arterial occlusion in closed head injury may result from DTH. Moreover, infarction may be attributed to the delayed effects of injury. (orig./GDG)

  7. 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.)

    2011-04-01

    Full Text Available Abstract Left atrial intramural hematoma is a seldom cause of left atrial mass. It has been described to occur spontaneously, after interventional procedures, after blunt chest trauma, or after aortocoronary bypass surgery. We present a case of mitral valve replacement together with the removal of a large intraatrial space-occupying lesion. Intraoperative transesophageal echocardiography confirmed a successful resection of this mass. Surprisingly, upon admission to ICU, transesophageal and transthoracic echocardiography revealed a recurrence of an intramural lesion, closest matching a hematoma, which was confirmed by contrast-enhanced computed tomography. Surgical intervention was thoroughly discussed but a conservative management was favoured. 3 months after surgery, a reassessed transthoracic echocardiography and computed tomography demonstrated an almost complete resolution of the pre-existing hematoma.

    In clinical forensic medicine, hematomas and other externally visible injuries build the basis for the reconstruction of events. However, dating of subcutaneous hematomas based on their external aspect is difficult. Magnetic resonance imaging (MRI) has proven its use in dating intracranial hemorrhage. Thus, the aim was to investigate if MRI can also be used for dating subcutaneous hematomas and to analyze an eventual influence of the hematoma shape. In 20 healthy volunteers (11 females, 9 males, aged 26.9?±?3.8 years), 4 ml of autologous blood were injected subcutaneously in the thigh. The hematoma was scanned immediately after the injection, after 3 and 24 h and 3, 7, and 14 days using three sequences with different contrast. Data was analyzed by measuring signal intensities of the hematoma, the muscle, and the subcutaneous tissue over time, and the Michelson contrast coefficients between the tissues were calculated. In the analysis, hematoma shape was considered. Signal intensity of blood in the proton density-weighted sequence reached its maximum 3 h after the injection with a subsequent decrease, whereas the signal intensities of muscle and fatty tissue remained constant. The time course of the Michelson coefficient of blood versus muscle decreased exponentially with a change from hyperintensity to hypointensity at 116.9 h, depending on hematoma shape. In the other sequences, either variability was large or contrast coefficients stayed constant over time. The observed change of contrast of blood versus muscle permits a quick estimate of a hematoma's age. The consideration of the hematoma shape is expected to further enhance dating using MRI.

  11. CT guided stereotactic evacuation for hypertensive intracerebral hematoma

    International Nuclear Information System (INIS)

    Sixty-one cases of hypertensive intracerebral hematoma were evacuated by CT guided stereotactic method. The operation was performed in the CT room under general anesthesia using the KOMAI-NAKAJIMA STEREOTACTIC DEVICE. This instrument has a micromanipulater that can be used for various kinds of stereotactic procedures. Three dimensional position of the target point (aspiration point of the hematoma) was determined on the film obtained from CT scanning of the patient in the stereotactic system. If the hematoma was small, the target point was enough to be one point at the center of the hematoma, but in case of the large hematoma, several target points were given according to the shape of hematoma. The probe, ordinarily a steel tube 4 mm in outer diameter, was inserted through brain to the target point and the hematoma was aspirated through a silicon tube connected to a vacuum system. Among 61 cases examined, 30 cases of thalamic hemorrhage were operated upon and 36 cases were not operated. They were classified according to the volume of hematoma into 3 groups as follows: A=less than 10 ml, B=11-25 ml, C=more than 25 ml. The operated cases were compared with the non operated cases on the improvement of consciousness in each group. In the A group, the operated patients in the level I recovered more slowly than the non operated patients, but in the level II patients, this was reversed. In the B group, the operated patients improved more quickly except the level I patients. more quickly except the level I patients. In the C group, almost all of non operated patients died. Thus, this operation was very useful in improving consciousness of level II or III patients independent of hematoma volume. It accelerated the recovery of motor function in the level I. This non inversive technique is considered effective for the removal of deep intracerebral hematoma. (author)

    An example of a traumatic extradural hematoma of the cervical spine that occurred in a 32-year-old man who suffered from chronic ankylosing spondylitis is reported. Progressive sensory and motor deficit ensued some 3 hours after the patient fell from a standing position. The patient landed on his back, striking his head on the floor. After being helped up, he was able to walk unassisted to a nearby chair, where he sat down until his left lower extremity--and shortly afterwards, the right one--became numb and weak. On admission, the patient was found to have tetraparesis that was more pronounced in the lower extremities and associated with incomplete sensation to pinprick at level T7-T10. He also had painless distention of the urinary bladder. After a few hours, the weakness in his limbs increased and his sensory level rose to C5 bilaterally. A horizontal diastatic fracture across the vertebral body of C7 was discovered on plain x-ray films of the spine, and an extradural hematoma extending dorsally from C5 to T1 was revealed by emergency magnetic resonance imaging. After an emergency decompressive cervical laminectomy and removal of the clot, the patient rapidly regained complete neurological function, except with regard to both the urinary bladder and the rectum, which remained abnormal for almost 7 weeks after the operation.

Abstract in english Introduction: Non-traumatic acute subdural hematoma is a rare entity in children. In the presence of acute neurological symptoms associated with long termanticoagulation, it is manda­tory to rule out this entity. Case report: We report the case of a seven-year-old boy, with mechanical mitral valve p [...] rosthesis under warfarin treat­ment, presenting severe and progressive headache associated with altered level of consciousness and seizures. Laboratory studies revealed a high value of International Normalized Ratio(INR: 4,2). He was admitted to the Pediatric Intensive Care Unit in a coma with anisocoria. He was mechanically ventilated and started on specific measures to reduce cerebral edemain ad­dition to anticonvulsants. Cranial computerized tomography (CT scan) revealed acute left subdural hematoma, with midline shift. Fifty-six hours after the onset of symptoms, he was submitted to decompressive craniectomy. There was progressive clinical re­covery with neurological and imaging improvement and an excel­lent outcome. Discussion: This case illustrates the importance of the clinical suspicion of a subdural hematoma in patients treated with anticoagulants, as well as the need of optimizing surgical condi­tions and the use of non invasive techniques for monitoring the level of consciousness.

    We present a case of intramural duodenal hematoma as a complication of endoscopic therapy for a bleeding duodenal ulcer in an adult patient with no evidence of other pathologies. A 18-year-old man was admitted in emergency room with gastrointestinal bleeding manifested by melena. Previous medical history revealed that he had endoscopic sclerotherapy for bleeding duodenal ulcer 5 months before. Endoscopy revealed a Forrest 2a ulcer in the duodenal bulb and sclerotherapy was performed by injecting 10 ml of 0.2% epinephrine and 20 ml of NaCl 0.9% solution. Upper occlusion’s signs appeared 36 hours after the procedure. The hematoma, that was identified by endoscopy and confirmed by MRI and CT scan of the abdomen, caused transient duodenal obstruction. Combined conservative management with nasogastric tube and total parenteral nutrition resulted in reduction of obstructive symptoms within 4 weeks. PMID:25827667

  18. Subdural Hematoma and Postdural Puncture Headache from Intrathecal Pump Placement Resolved with Lumbar Epidural Blood Patch

    2014-09-01

    Full Text Available Intrathecal drug delivery systems are commonly used in the management of chronic pain, cancer pain and neuromuscular disorders with muscle spasticity. The complications associated with in-trathecal pump placement include persistent cerebrospinal fluid (CSF leak, hygroma, meningitis, and granuloma formation. A severe persistent CSF leak may cause postdural puncture headache along with acute intracranial subdural hematoma, which can be potentially life threatening. Surgical exploration with dural repair is required to treat this severe complication when conservative treatments fail. We present a case report of severe persistent CSF leak after intrathecal pump revision that resulted in a subdural hematoma and postdural puncture headache. In this case, an epidural blood patch was performed using epidural catheter under fluoroscopic guidance to target the site of CSF leak and to avoid damaging the intrathecal catheter. This patient’s headache was resolved and intrathecal catheter remained intact after this blood patch.

  19. 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.

  20. Clinical studies on cerebral blood flow in chronic subdural hematoma

    International Nuclear Information System (INIS)

    Cerebral blood flow (CBF) and clinical symptoms were examined between pre- and post-operations in twenty-four patients with unilateral chronic subdural hematoma. The following results were obtained by intravenous 133Xe method : 1. There was a reducing tendency of the CBF (hemisphere) on hematoma side, in most cases. While, the groups of headache and disturbances of consciousness did not give a laterality between hematoma and opposite side without the group of hemiparesis. 2. The absolute values of the CBF in the groups of headache and disturbances of consciousness were correlated with the clinical symptoms. In the group of hemiparesis, the laterality between hematoma and opposite side was correlated with the clinical symptoms. 3. In the group of hemiparesis, the F-flow (fast-flow) had sensitive reaction more than the ISI (initial slope index) with symptomatic improvement. 4. It was found that there was not an increase in the absolute value of the CBF, which was under the normal limit between pre- and post-operations in the case without improvement. By SPECT (Method of IMP), the following results were obtained : 1. There was the area of defect at the location of hematoma and the CBF tended to reduce at the subcortical white matter and at the basal ganglia of hematoma side. 2. The CBF of the contralateral hematoma side in the hemisphere of cerebellum was also tended to reduce. (author)

  1. 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.

    Subdural hematomas (SDH) are associated with an increased morbidity and mortality and generally occur as chronic SDH among older patients. The most frequent signs and symptoms - like headache, alteration of consciousness, gait impairment and hemiparesis - are also prevalent among other diseases, which has to be taken into account in the differential diagnosis. In the case of symptomatic patients with focal neurological deficits, a surgical intervention should be considered, whereas in case of asymptomatic patients or patients with only slight headaches, also a conservative treatment with a clinical and radiological follow-up might be a possibility. Also after surgical intervention, the recurrence rate is between 5 and 33%. Therefore, all patients with chronic SDH depict, irrespective of the indication for an oral anticoagulation, a challenge for the treating physicians. PMID:20960397

  3. 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.)

Surgery performed within 8 hours makes good or partial recovery of neurologic function. Our patient was also started on higher dose of LMWH and developed neurological deficits due to a SEH following lumbar puncture. She underwent operation after six days and she had a mild recovery following the operation. Current administration of high doses of LMWH can cause SEH even after a lumbar puncture, which was performed without multiple attempts. Although surgery performed within 8 hours makes good or partial recovery of neurologic function, laminectomy and epidural hematoma evacuation performed after three days can also have successful results.

  6. Short Conduction Delays Cause Inhibition Rather than Excitation to Favor Synchrony in Hybrid Neuronal Networks of the Entorhinal Cortex

    How stable synchrony in neuronal networks is sustained in the presence of conduction delays is an open question. The Dynamic Clamp was used to measure phase resetting curves (PRCs) for entorhinal cortical cells, and then to construct networks of two such neurons. PRCs were in general Type I (all advances or all delays) or weakly type II with a small region at early phases with the opposite type of resetting. We used previously developed theoretical methods based on PRCs under the assumption o...

    Hepatobiliary radionuclide imaging is typically performed to detect cholecystitis. Infrequently, imaging reveals an obstructive pattern. Although delayed hepatobiliary imaging is commonly used to differentiate between intrahepatic (IH) and extrahepatic (EH) obstruction in the newborn; there is room to clarify the use of delayed imaging in the adult population. A retrospective review was performed of adult patients demonstrating a complete obstructive pattern on initial Tc-99m mebrofenin hepat...

  8. Effects of catheter size on hematoma formation after diagnostic angiography

    International Nuclear Information System (INIS)

    This paper reports on the effect of catheter size or the development of groin hematomas after diagnostic angiography. Four hundred eighty-one patients undergoing diagnostic peripheral angiography were randomized to receive either a 5-F or 7-F catheter. Patients were assessed immediately and 24 hours after the procedure for development of either small (10 cm) hematomas. For 5-F versus 7-F catheters, hematomas developed as follows: small, 9.2% versus 18.0% (P < .05); moderate, 0.8% versus 1.3%; and large, 0.4% versus 0.0%. Findings were similar at 24 hours. The difference in incidence of small hematomas between 5-F and 7-F groups was not related to age, weight, coagulation studies, blood pressure, procedure time, or compression time

  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.)

    Trauma-induced hematomas of the limbs usually resorb without sequelae. In certain circumstances which are not fully understood, the hematoma may expand progressively, eventually leading to the development of a tumor-like mass in the soft tissues. We report the case of a chronic expanding hematoma observed in the right soleus muscle of a 75-year-old man. The mass grew +9 cm compared with the other side over a period of two to three years with no notion of recent trauma. Surgical biopsy disclosed a thick capsule containing "chocolate pus". Pathology and cytology examination led to the diagnosis of pseudo-tumor calcinosis subsequent to a hematoma which the patient had developed 34 years earlier when as a mountain guide he had experienced a tear of the soleus muscle. Local care required complete resection of the soleus muscle. The patient was able to resume activities without pain. Well described in the literature, encapsulated hematoma of the limbs is not well known in France. This case illustrated the potentially long latency period (34 years in our patient). Pathologically similar to tumor calcinosis, chronic expanding hematoma should be entertained as a possible diagnosis in a patient with a longstanding mass and a history of past trauma. The differential diagnosis with sarcoma is established by magnetic resonance imaging which reveals a peripheral low intensity signal on T1 and T2 sequences. PMID:17124458

  14. The outcome of the acute subdural hematoma

    International Nuclear Information System (INIS)

    Thirty-five cases of acute subdural hematoma (ASDH) were reviewed and divided into two groups of A and B according to the outcome. The findings of computed tomography (CT) and the time interval between head trauma and surgical intervention were investigated to know the factors that influence the prognosis in ASDH. 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 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.)

    Full Text Available Warfarin is frequently used as an oral anticoagulant in a variety of clinical settings, e.g. atrial fibrillation or following valvular heart disease. The most serious and common complication associated with anticoagulation using warfarin is bleeding. Hemorrhage into the iliopsoas muscle causing femoral neuropathy is an infrequent complication of anticoagulant therapy. Two women, 53 and 70 year-old, each with a history of mitral valve replacement surgery, presented at the emergency department with right hip pain. They had been taking warfarin 5 mg once a day since their operations. Physical examinations were normal except for the right hip pain,on movement and femoral nerve palsy in the second patient. Prothrombin, activated prothrombin time and international normalized ratio were prolonged. In order to make the differential diagnosis, we decided to perform bedside emergency ultrasound examination. Ultrasound examination of the patients showed an anechoic lesion in the area of the right iliopsoas muscle. They were admitted to hospital for observation and treatment. Fresh frozen plasma and vitamin K were given for treatment. The possibility of iliopsoas hematoma should be considered in any patient with hip pain undergoing anticoagulant treatment.

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.

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.

  18. Tissue thiamine deficiency as potential cause of delayed graft function after kidney transplantation: thiamine supplementation of kidney donors may improve transplantation outcome.

    Science.gov (United States)

    Klooster, Astrid; Leuvenink, Henri G D; Gans, Rijk O B; Bakker, Stephan J L

    2007-01-01

    Delayed graft function is an important medical problem after renal transplantation. It occurs in approximately 30% of cases, and is not only associated with more prolonged and complicated hospitalisation, but also with earlier graft loss on the long-term. Delayed graft function is the consequence of acute tubular necrosis caused by ischaemia-reperfusion injury, with insufficiently opposed toxic effects of reactive oxygen species and insufficient ATP regeneration. An optimal tissue thiamine status is pivotal for scavenging of reactive oxygen species and regeneration of ATP. There are several reasons to suppose that tissue thiamine availability is suboptimal in donor kidneys prior to reperfusion in transplantation. These reasons include a high prevalence of untreated thiamine deficiency at admission of donors to intensive care units, quick exhaustion of body thiamine stores during periods of non-feeding or inappropriate feeding during hospital stays of donors, and loss of the water-soluble vitamin into water-based organ preservation solutions. We therefore hypothesize that a suboptimal tissue thiamine status is a cause of delayed graft function after renal transplantation, and that it can be prevented with thiamine supplementation.

    Directory of Open Access Journals (Sweden)

    2011-07-01

    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.

    Snake bite envenomation is a common cause of acute kidney injury (AKI) in the tropics and severe coagulopathy with bleeding manifestations is usually seen, especially with viperine bites. We present a case of a 34-year-old male who had developed AKI following Russell's viper envenomation along with disseminated intravascular coagulation. The patient was seemingly improving during the course of his treatment but subsequently developed a spontaneous unilateral peri-nephric hematoma and finally succumbed to this complication. This is a rare presentation that can be clinically innoccuous in a disease where there are multiple bleeding manifestations and, carries a very poor outcome. PMID:25758885

    Carex meadows are critical habitat for wintering geese in the floodplains of the middle and lower reaches of Yangtze River, China. These meadows follow a growth cycle closely tied to the seasonal hydrological fluctuation: as water levels recede in the fall, exposed mudflats provide habitat for Carex spp. growth. The seasonal growth of Carex overlaps the arrival of wintering geese and provides an important food source for the migrants. Recent alterations to the Yangtze's hydrology, however, have disrupted the synchronous relationship between water levels, Carex growth and wintering geese at Dongting Lake. In October 2012, we carried out an outdoor mesocosm experiment to investigate potential impacts of delayed water recession on the germination and growth of Carex heterolepis, the dominant Carex species at Dongting Lake, to understand how changes in hydrology might impact wintering goose habitat. Results showed that the delayed flood recession exerted significant impact on the first growth cycle of Carex growth. Prolonged inundation significantly lowered the intrinsic growth rate (P = 0.03) and maximum growth rates (P = 0.02). It also took significantly longer time to reach the peak growth rate (P = 0.04 and 0.05 for number of shoot and biomass, respectively). As a result, biomass accumulation was reduced by 45, 62 and 90 % for 10-day, 20-day and 30-day inundation treatments, respectively. These results indicate a severe risk of food shortage for wintering geese when water recession delayed. This potential risk should be taken into consideration when operating any hydrological control structures that alter the flood regimes in Dongting Lake. PMID:25164981

As a result, biomass accumulation was reduced by 45, 62 and 90 % for 10-day, 20-day and 30-day inundation treatments, respectively. These results indicate a severe risk of food shortage for wintering geese when water recession delayed. This potential risk should be taken into consideration when operating any hydrological control structures that alter the flood regimes in Dongting Lake.

    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.

    The role of lactic acid bacteria for a correct course of fermentation of table olives has been extensively reviewed and it is a common idea that the inoculum of selected strains could exert a strong benefit for product quality; however, the basic assumption of this research is that a not-correct preparation of starter could affect its performances in brines and delay the benefit of a starter inoculum. Thus, some selected strains of LAB (lactic acid bacteria) and yeasts were inoculated into br...

    Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can be observed within the first 24?h after symptom onset, but predominantly occurs in the early hours....

    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

  10. The delayed terminal flower phenotype is caused by a conditional mutation in the CENTRORADIALIS gene of snapdragon.

    2001-07-01

    The snapdragon (Antirrhinum majus) centroradialis mutant (cen) is characterized by the development of a terminal flower, thereby replacing the normally open inflorescence by a closed inflorescence. In contrast to its Arabidopsis counterpart, terminal flower1, the cen-null mutant displays an almost constant number of lateral flowers below the terminal flower. Some partial revertants of an X-radiation-induced cen mutant showed a delayed formation of the terminal flower, resulting in a variable number of lateral flowers. The number of lateral flowers formed was shown to be environmentally controlled, with the fewer flowers formed under the stronger flower-inducing conditions. Plants displaying this "Delayed terminal flower" phenotype were found to be heterozygous for a mutant allele carrying a transposon in the coding region and an allele from which the transposon excised, leaving behind a 3-bp duplication as footprint. As a consequence, an iso-leucine is inserted between Asp148 and Gly149 in the CENTRORADIALIS protein. It is proposed that this mutation results in a low level of functional CEN activity, generating a phenotype that is more similar to the Arabidopsis Terminal flower phenotype. PMID:11457954

  11. Prediction and observation of post-admission hematoma expansion in patients with intracerebral hemorrhage

    2014-01-01

    Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can be observed within the first 24?h after symptom onset, but predominantly occurs in the early hours. Thus capturing markers of on-going bleeding on imaging techniques could predict hematoma expansion. The spot sign observed on computed tomography angiography is believed to represent on-going bleeding and is to date the most well investigated and reliable radiological predictor of hematoma expansion as well as functional outcome and mortality. On non-contrast CT, the presence of foci of hypoattenuation within the hematoma along with the hematoma-size is reported to be predictive of hematoma expansion and outcome. Because patients tend to arrive earlier to the hospital, a larger fraction of acute ICH-patients must be expected to undergo hematoma expansion. This renders observation and radiological follow-up investigations increasingly relevant. Transcranial duplex sonography has in recent years proven to be able to estimate hematoma volume with good precision and could be a valuable tool in bedside serial observation of acute ICH-patients. Future studies will elucidate, if better prediction and observation of post-admission hematoma expansion can help select patients, who will benefit from hemostatic treatment.

    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. Enlarged cerebrospinal fluid spaces in infants with subdural hematomas

    International Nuclear Information System (INIS)

    Computed tomography in 16 infants with subdural hematomas showed enlarged basal cisterns, a wide interhemispheric fissure, prominent cortical sulci, and varying degrees of ventricular enlargement. Radionuclide cisternography in eight of the 16 patients showed findings consistent with enlargement of the subarachnoid space rather than those of communicating hydrocephalus. Clinical findings and brief follow-up showed no convincing evidence for cerebral atrophy in 13 patients. These findings suggest that the enlarged subarachnoid space, which is encountered in some infants and may be a developmental variant, predisposes such infants to subdural hematomas

    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

  16. CT imaging of aortic intramural hematoma: Report of two cases, and review of literature

    International Nuclear Information System (INIS)

    Aortic intramural hematoma (IMH) is a relatively rare, but potentially fatal pathology, which is most commonly diagnosed under emergency conditions with computed tomography angiography (CTA). We present two cases of IMH examined with different CTA protocols, which resulted in diverse diagnoses. In the first patient, contrast-enhanced CTA revealed dilatation of thoracic aorta and polymorphic wall thickening. It was misdiagnosed as being a mural thrombus and was complicated by acute dissection. In the second patient, non-enhanced CT revealed hyperdense aortic wall thickening. The patient was diagnosed as having type B IMH but he died due to aortic rupture. In our opinion, CT examination of the aorta in emergency cases should always include non enhanced scanning. Any delay in proper diagnosis and treatment of IMH may result in serious complications. (authors)

    2013-01-01

    Background?Cases of posttraumatic arteriovenous (AV) fistula of the distal lower limb are rarely reported. Time from trauma to diagnosis varies from hours to years. Case Description?This case report of a 51-year-old male patient shows very impressively the extensive consequences of an unrecognized traumatic AV fistula. The fistula developed here after a car accident led to a massive healing delay in a pilon fracture of the tibia and a wound, resulting in almost 1?year immobilization, 20 operations, and extensive pain drug therapy. After surgical revision of the fistula, bone and wound healing improved quickly. Conclusions?The possibility of an AV fistula should be considered in case of persistent swelling after high-energy trauma of an extremity. The therapy of choice is surgery and the long-term result of successful fistula ligature is excellent. PMID:25798368

  7. Delayed Puberty

    2011-03-01

    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

  9. An increase in melatonin in transgenic rice causes pleiotropic phenotypes, including enhanced seedling growth, delayed flowering, and low grain yield.

    Byeon, Yeong; Back, Kyoungwhan

    2014-05-01

    No previous reports have described the effects of an increase in endogenous melatonin levels on plant yield and reproduction. Here, the phenotypes of melatonin-rich transgenic rice plants overexpressing sheep serotonin N-acetyltransferase were investigated under field conditions. Early seedling growth of melatonin-rich transgenic rice was greatly accelerated, with enhanced biomass relative to the wild type (WT). However, flowering was delayed by 1 wk in the transgenic lines compared with the WT. Grain yields of the melatonin-rich transgenic lines were reduced by 33% on average. Other phenotypes also varied among the transgenic lines. For example, the transgenic line S1 exhibited greater height and biomass than the WT, while the S10 transgenic line showed diminished height and an increase in panicle numbers per plant. The expression levels of Oryza sativa homeobox1 (OSH1) and TEOSINTE BRANCHED1 (TB1) genes, two key regulators of meristem initiation and maintenance, were not altered in the transgenic lines. These data demonstrate that an alteration of endogenous melatonin levels leads to pleiotropic effects such as height, biomass, panicle number, flowering time, and grain yield, indicating that melatonin behaves as a signaling molecule in plant growth and reproduction.

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.

    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. A paciente recebeu alta hospitalar 86 horas depois do início do tratamento conservador, sem comprometimento neurológico. Uma tomografia computadorizada de controle, após sete meses, mostrou o canal vertebral completamente normal. CONCLUSÕES: A eficiência da abordagem conservadora mostrou-se uma alternativa importante à intervenção cirúrgica em casos específicos. A avaliação da progressão ou a estabilização do comprometimento neurológico, sobretudo após a oitava hora após a punção peridural, é essencial para a escolha do tratamento.JUSTIFICATIVA Y OBJETIVOS: O hematoma asociado a la compresión espinal después de la anestesia peridural es una complicación neurológica grave, a pesar de la pequeña incidencia relatada (1:150.000.

    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. PMID:25969617

  18. Characteristic MRI and MR Myelography Findings for the Facet Cyst Hematoma at T12-L1 Spine: A Case Report

    International Nuclear Information System (INIS)

    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.

    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.

  20. The question is whether hemiparesis is more common in unilateral than bilateral chronic subdural hematoma

    2014-01-01

    Full Text Available Introduction. Chronic subdural hematoma is an intracranial hemorrhagic lesion that illustrates various expressions in clinical and radiological practice. The aim of this study was to emphasize the correlation between the brain site of chronic subdural hematoma and clinical symptoms/signs of disease. Furthermore, the study denotes the significance of hemiparesis occurrence in the patients with unilateral chronic subdural hematomas more than in those with bilateral ones, associated with time required to diagnose hematoma. Material and Methods: A three-year study included 72 patients with chronic subdural hematoma. According to their clinical and neurological symptoms on hospital admission, all patients underwent non-contrast brain computed tomography scan, which confirmed the diagnosis. The radiological parameters, inlcuding the site of chronic subdural hematoma, a hematoma width and midline shift were recorded to give precise data about the correlation with neurological symptoms. A special focus was put on the lag time between the onset of symptoms and signs to diagnosis of chronic subdural hematoma. Results. The study proved that the patients with unilateral chronic subdural hematoma had more frequent occurrence of hemiparesis than the patients with bilateral chronic subdural hematoma. It took the left-sided chronic subdural hematomas less time (about 200 hours earlier than the rightsided ones to present its symptoms although the average hematoma diameter value was almost the same. Conclusion. The site and the form of intracranial lesion-chronic subdural hematoma could have a great influence on neurological and functional condition in a patient. Although the length of time required for making diagnosis as well as clinical symptoms greatly differ and the latter are not always so clear, physicians should maintain a high level of suspicion for this disease and thus contribute to prompt diagnosis and better clinical outcome of patients.

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. Recomenda-se a realização de ecocardiografia transesofágica, quando disponível, antes da inserção de um balão intra-aórtico de contrapulsação em pacientes submetidos à ressuscitação cardiopulmonar. 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

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

  6. 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

    Aural hematomas in 9 dogs were managed by manual expression through stab incisions in the pinna and placement of indwelling silicone rubber drains, without compression bandaging. The drains were well tolerated. Seromas developed in 2 ears when the drains were removed at 7 and 10 days, but the seromas resolved when the drains were replaced. Healing without deformation of the pinna was obtained when the drains were maintained 13 to 28 days. PMID:12002588

    Information about computerized tomography (CT) of arachnoid cysts of the middle fossa (ACMF) is increasing, and it appears that certain CT characteristics may be diagnostic. The association of ACMF and subdural hematoma has been emphasized previously but is not common knowledge. We present three new cases of ACMF and associated subdural hematoma studied by plain roentgenograms, EEG, conventional brain scanning, CT scanning, and angiography. The cysts were clearly shown in each case by CT scan, but no subdural hematoma was visualized in our first two cases. Angiography was necessary to establish the associated hematoma. We review and emphasize computerized tomographic characteristics that may be pathognomonic of ACMF. It is suggested that angiography be included in the study of patients symptomatic with ACMF because associated subdural hematoma is not an uncommon lesion and may fail to visualize on CT scan. Angiography still remains the most conclusive study to establish or exclude the diagnosis of subdural hematoma. PMID:623534

Brucellosis occurs after direct contact with an infected animal or consumption of products of an infected animal. Subcapsular hematoma in the spleen is very rare complication of brucella infection. We report here, an 11 year old patient with brucellosis who admitted to our clinic with subcapsular non-traumatic spleen hematoma. Hematoma and clinical findings were resolved with doxicyclin and streptomycin combination. We emphasised that brucella infection should be keept in mind when non-traumatic subcapsular spleen hematoma occur.

    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.)

    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).

    Special attention has been given to the differences between subungual exostosis and subungual osteochondroma. Once a diagnosis has been made and symptoms persist, complete excision of the lesion with curettage of the base is the treatment of choice for both conditions. Subungual hematoma is an exquisitely painful condition that usually results from trauma, but may also be caused by systemic pathology, medication and drug reactions, and aging. Prompt decompression will significantly reduce pain and further damage to the nail bed and matrix. Radiographs must be taken because of the high incidence of associated distal phalangeal fracture. Patients must be warned that onycholysis, transient and permanent nail deformity, and infection are possible complications, even with the best treatment. PMID:2650846

    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.

    A 53-year-old-man underwent US-guided percutaneous thermal ablation with a cooled-tip needle of three liver metastases from gastric cancer. Six days later, the patient was re-admitted for melena, scleral jaundice, and anemia. Abdominal US disclosed echogenic material in the gallbladder lumen (hemobilia) and a focal lesion with mixed echotexture in segment III (hepatic hematoma). On day 5 portal cavernomatosis was diagnosed at US and confirmed by color Doppler and a helical CT exam. The case described emphasizes that radio-frequency interstitial hyperthermia may cause not only traumatic injury of the liver parenchyma but also thermally mediated damage of vascular structures.

Some patients remain non diagnosed in spite of being fully checked. Our objetive is to analyze those patients whose etiology could not be found. Material ando Method. From March 2006 to April 2009 we studi [...] ed 39 patients with ICH . Trauma and coagulation disorders were excluded. 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.

  19. Unilateral optic neuropathy following subdural hematoma: a case report

    Full Text Available Abstract Introduction Unilateral optic neuropathy is commonly due to a prechiasmatic affliction of the anterior visual pathway, while losses in visual hemifields result from the damage to brain hemispheres. Here we report the unusual case of a patient who suffered from acute optic neuropathy following hemispherical subdural hematoma. Although confirmed up to now only through necropsy studies, our case strongly suggests a local, microcirculatory deficit identified through magnetic resonance imaging in vivo. Case presentation A 70-year-old Caucasian German who developed a massive left hemispheric subdural hematoma under oral anticoagulation presented with acute, severe visual impairment on his left eye, which was noticed after surgical decompression. Neurologic and ophthalmologic examinations indicated sinistral optic neuropathy with visual acuity reduced nearly to amaurosis. Ocular pathology such as vitreous body hemorrhage, papilledema, and central retinal artery occlusion were excluded. An orbital lesion was ruled out by means of orbital magnetic resonance imaging. However, cerebral diffusion-weighted imaging and T2 maps of magnetic resonance imaging revealed a circumscribed ischemic lesion within the edematous, slightly herniated temporomesial lobe within the immediate vicinity of the affected optic nerve. Thus, the clinical course and morphologic magnetic resonance imaging findings suggest the occurrence of pressure-induced posterior ischemic optic neuropathy due to microcirculatory compromise. Conclusion Although lesions of the second cranial nerve following subdural hematoma have been reported individually, their pathogenesis was preferentially proposed from autopsy studies. Here we discuss a dual, pressure-induced and secondarily ischemic pathomechanism on the base of in vivo magnetic resonance imaging diagnostics which may remain unconsidered by computed tomography.

  20. In vivo polymerization of poly(3,4-ethylenedioxythiophene) in the living rat hippocampus does not cause a significant loss of performance in a delayed alternation task

    After extended implantation times, traditional intracortical neural probes exhibit a foreign-body reaction characterized by a reactive glial sheath that has been associated with increased system impedance and signal deterioration. Previously, we have proposed that the local in vivo polymerization of an electronically and ionically conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), might help to rebuild charge transport pathways across the glial scar between the device and surrounding parenchyma (Richardson-Burns et al 2007 J. Neural Eng. 4 L6-13). The EDOT monomer can be delivered via a microcannula/electrode system into the brain tissue of living animals followed by direct electrochemical polymerization, using the electrode itself as a source of oxidative current. In this study, we investigated the long-term effect of local in vivo PEDOT deposition on hippocampal neural function and histology. Rodent subjects were trained on a hippocampus-dependent task, delayed alternation (DA), and implanted with the microcannula/electrode system in the hippocampus. The animals were divided into four groups with different delay times between the initial surgery and the electrochemical polymerization: (1) control (no polymerization), (2) immediate (polymerization within 5 min of device implantation), (3) early (polymerization within 3-4 weeks after implantation) and (4) late (polymerization 7-8 weeks after polymerization). System impedance at 1 kHz was recorded and the tissue reactions were evaluated by immunohistochemistry. We found that under our deposition conditions, PEDOT typically grew at the tip of the electrode, forming an ˜500 µm cloud in the tissue. This is much larger than the typical width of the glial scar (˜150 µm). After polymerization, the impedance amplitude near the neurologically important frequency of 1 kHz dropped for all the groups; however, there was a time window of 3-4 weeks for an optimal decrease in impedance. For all surgery-polymerization time intervals, the polymerization did not cause significant deficits in performance of the DA task, suggesting that hippocampal function was not impaired by PEDOT deposition. However, GFAP+ and ED-1+ cells were also found at the deposition two weeks after the polymerization, suggesting potential secondary scarring. Therefore, less extensive deposition or milder deposition conditions may be desirable to minimize this scarring while maintaining decreased system impedance.

    An 80-year-old woman presented with a huge intrathoracic mass which had increased in size over 4 years. Computed tomography showed a thick calcified capsule and early-enhanced streaks inside the mass. Needle biopsy aspirated pure blood and fibrous connective tissue. F-18 fluorodeoxyglucose positron-emission tomography showed moderate FDG uptake at the periphery with central photon defects. Gallium-67 scintigraphy showed no abnormal uptake. On suspicion of chronic expanding hematoma, we recommended surgical resection, but the patient requested only follow-up. One year later, she was hospitalized with cardiac tamponade and subsequent massive hemoptysis. Repeated embolization was ineffective, and the patient soon succumbed. PMID:23050116

    Development of collateral circulation belongs among the typical signs of aortic coarctation. Cerebral or spinal artery aneurysm formation with increased risk of subarachnoid hemorrhage represent the most common neurovascular complication of this disease. We report a case of a 20-year-old sportsman who developed acute non-traumatic paraplegia as a result of extensive spinal epidural hemorrhage from collateral vessels accompanying aortic coarctation which was unrecognized up to that time. To the best of our knowledge, acute spinal epidural hematoma as a complication of aortic coarctation has not been previously reported. (orig.)

    International Nuclear Information System (INIS)

    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)

    International Nuclear Information System (INIS)

    Hepatic hematomas are relatively common in fetuses and neonates; most are subcapsular in location. 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 ?-fetoprotein level. We report a case of intrahepatic hematoma with a rising ?-fetoprotein level. (orig.)

    Objective The authors evaluated the feasibility and targeting accuracy of CT fluoroscopy (CTF)-guided catheter placement and aspiration of intracerebral hematoma (ICH)s. Materials and Methods Nine patients (mean age, 63.3 ± 15.3 years) were treated by CTF-guided hematoma aspiration under local anesthesia. The targeting errors in the lesion center, volume of the aspirated hematoma, accuracy of the final catheter position, procedure time, and clinical outcomes were evaluated. Results All catheters were successfully placed in the center of the hematoma. The mean volume of the aspirated hematoma was 20.6 ± 8.8 mL (pre-treatment, 44.7 ± 20.1 mL; post-treatment, 24.1 ± 13.8 mL). The average procedure time was 25.1 minutes (range, 18-32 minutes). In one case with a scanty residual hematoma, the catheter was removed at the end of the procedure. In the remaining eight cases, the catheter was left in the residual hematoma for drainage and all catheter tips were accurately located in the final position. There were no procedure-related complications, including rebleeding and infection. Conclusion CTF-guided ICH aspiration is a feasible, quick, and accurate procedure which could substitute for stereotactic methods. The accurate catheter position provided by real-time observation enables an effective aspiration and drainage of hematomas. PMID:25874179

    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. PMID:25684931

    A new technique using the carbon dioxide (CO2) laser for the treatment of aural hematomas is described. The laser is used to make an incision into the hematoma to allow for evacuation of the blood, and then multiple, small incisions are made over the surface of the hematoma to stimulate adhesions between the tissue layers. The CO2 laser was used in this fashion to treat 10 aural hematomas in eight dogs. Follow-up ranged from 1 to 23 months. Owners evaluated the cosmetic results following CO2 laser surgery as excellent in three ears, good in five ears, and fair in two ears. Hematomas were resolved in all 10 cases, although two cases developed serosanguineous fluid accumulation that required percutaneous drainage in one case and a second laser procedure in the other case.

A cirurgia foi sem intercorrências, e a paciente recebeu alta hospitalar. Após 48 horas da punção raquidiana, a paciente relatou cefaleia de início súbito, de forte intensidade, acometendo principalmente a região orbitária, mas também a região temporal, com melhora importante no decúbito dorsal e acompanhada de dois episódios de vômitos. Foi solicitada tomografia de crânio que revelou a presença de um hematoma subdural agudo frontotemporoparietal esquerdo. Foi indicado tratamento conservador com analgésicos, dexametasoma e hidantoína. Após 17 dias, apresentou quadro de cefaleia intensa, acompanhada de dormência e paresia do membro superior direito, e distúrbio da fala e comportamento. O hematoma foi drenado cirurgicamente.

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

    Full Text Available From this short review, immerges a syndrome of the chronic subdural hematoma. The patient is usually an elderly male', with a hisory of moderate or severe trauma to the head incurred about 2 months prionjto admission, with or witout immediate headache which subsides, then recurs lllb6ut two to three weeks prior to admission. The headache becomes severer and the patient may develop a hemiparesis most frequently contralaterally, would become drowsy and may enter coma if not diagnosed and treated early. On examination, he would show dulled mental capacities and possibly papilloedema, with or without a hemiparesis and in one fifth of the cases a peculiar type of disturbance of gait. If there has been waxing and waning of the symptomatology in the past few days. this adds to the completeness of the picture. Although there is a syndrome that caracteriscs cases of subdural hematomas, the picture can be very varied and there is no doubt that the final diagnosis rests with angiography, which shows a typical appearance of an avascular lens shaped area just under tho parietal bone on the AP films or in some cases under the frontal bone in oblique film

    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.

Revisamos retrospectivamente 12 casos de pacientes con quiste aracnoideo que presentaron como comp [...] licación un hematoma subdural crónico. Resultados. Entre enero de 1984 y abril de 2008, 12 pacientes (0.9%) de 1.253 casos con hematoma subdural crónico presentaban un quiste aracnoideo intracraneal. La localización de los quistes fue en 10 casos en la fosa temporal y los otros dos en la convexidad. Los síntomas de presentación fueron cefalea en 6 pacientes (50%), seguidos por convulsiones (3 casos). En once pacientes se realizó agujero de trépano y drenaje del HSC, la paciente de más edad fue tratada de forma conservadora. Únicamente se trataron 3 quistes aracnoideos mediante craneotomía y fenestración, con resolución completa del quiste. Conclusiones. Los pacientes con quiste aracnoideo, sobre todo si esta localizado en la fosa temporal, tienen un mayor riesgo de sufrir un hematoma subdural crónico. La primera opción terapéutica es el drenaje del hematoma subdural y si persiste la sintomatología deberá tratarse el quiste aracnoideo. Abstract in english Introduction. We designed this study to investigate the clinical, neurological, and radiological outcome of patients with chronic subdural hematoma related to an intracranial arachnoid cysts. Patients and methods. Medical records of 12 cases of patients with arachnoids cyst complicated with chronic [...] subdural hematoma were retrospectively reviewed. Results. Between January 1984 and April 2008, 12 patients (0.9%) of 1.253 cases of chronic subdural hematoma surgically treated in our hospital had associated arachnoid cyst. Arachnoid cysts were located in the middle fossa (10 cases) and convexity (2 cases). The most frequent symptom was headache (6 cases), followed by seizures (3 cases). Eleven patients underwent burr hole and drainage; the oldest patient was treated conservatively. Conclusions. Patients with AC, especially when these are located in temporal fossa, appear to harbour a life-long risk of contracting subdural hematoma. Hematoma evacuation is adequate at first operation and if arachnoid cyst is symptomatic or preoperative symptoms persist, additional arachnoid cyst surgery should be considered.

  7. Chronic subdural hematoma associated with moyamoya phenomenon after radiotherapy for medulloblastoma

    International Nuclear Information System (INIS)

    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 me 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.

    Brucellosis is one of the most common zoonotic diseases worldwide with a variable frequency in European countries. Brucellosis is usually transmitted after direct contact with or consumption of dairy products from an infected animal. Initially, our patient, a 65 year-old man, had nonspecific manifestations of fever, malaise, headache, anorexia and arthralgia which are the classic symptoms of this disease. After the diagnosis of brucellosis had been confirmed by blood culture and serology, progressive thrombocytopenia developed in spite of appropriate antibiotic administration. Radiological investigation revealed imaging findings consistent with splenic rupture. The complete recovery was observed after administration of antibiotic therapy and platelet transfusion. Spontaneous rupture of the spleen with subcapsular hematoma is an extremely rare condition in brucellosis. We want to remind clinicians of this rare complication. PMID:22490460

    Full Text Available Background: Chronic subdural hematoma (CSDH is a common complication in head injuries. The objective of this study is to establish the evolution of traumatic subdural effusion (TSDE into CSDH using clinical signs and symptoms as well as radiology. Our aim is to effectively manage such cases without postoperative recurrence (PR. Methodology: The study was a retrospective cohort carried out in the No. 1 People’s Hospital of Jingzhou from August 2007 to November 2013. The hospital is affiliated to the Yangtze University. All the patients included in this study were involved in road traffic accidents and sustained various degree of head injury. Serial CT scans were done to establish the development TSDE and the evolution of the TSDE into CSDH and treatment options. Results: In all 159 patients developed TSDE and out of these 34 which constitute 21.38% had their TSDE evolving into CSDH. Most of the patients were elderly. Twelve patients were treated conservatively while the remaining patients were treated surgically by drilling and drainage of hematoma. All the patients survived with marked improvement in their sign and symptoms with no recurrence. Conclusion: TSDE is one of the etiological factors for the development of CSDH in the elderly although in most cases the etiology of CSDH is usual multifactory. It must be stated clearly that, the evolution of TSDE into CSDH is initially a hidden process and presents with nonspecific signs and symptoms which can easily be missed. CT scan is usually the initial radiology of choice in making diagnosis of TSDE but MRI could be used to make early diagnosis of the transgression of TSDE into CSDH, and hence early surgical intervention before the formation of a neomembrane could reduce PR rate.

  13. MR imaging of epidural hematoma in the lumbar spine

    International Nuclear Information System (INIS)

    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 wh 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.)

    Radiation-induced vasculopathy is a rare occurrence, however, it is one of the most serious complications that can occur after gamma-knife radiosurgery (GKRS). The authors present two cases of incidentally found deep cerebral arteriovenous malformation (AVM), which were treated by GKRS, where subsequently there occurred delayed-onset cerebral infarction (11 and 17 months after GKRS) at an area adjacent to the AVM. In both cases, perforators of the M1 segment of the middle cerebral artery were included in the radiation field and delayed injury to these is suggested to be the mechanism of the ischemic event.

  15. Non-traumatic acute epidural spinal hematomas diagnosed by magnetic resonance

    International Nuclear Information System (INIS)

    The non-traumatic spinal epidural hematoma (NTSEH) is a rare entity that can be the cause of an acute spinal compression syndrome. the objective of this review is to identify the characteristics by MRI and NTSEH and to analyze the factors that influence in its prognosis. In the years 1994 and 1999, 12 patients with NTSEH have been diagnosed in our hospital, and a MRI was performed during the acute phase. the characteristics of the lesions have been analyzed by MRI, with special emphasis on the topographic data and resonance signal and the factors that can influence in the clinical prognosis of the patients. Initially, all of the patients presented pain in the cervical dorsal or interscapular site, followed by a sensitive-motor deficit picture. The MRI showed a lesion of expansive character and posterior epidural location in every case that would produce varying degrees of compression on the spinal cord. The NTSEH should be considered as one of the causes of acute spinal cord compression. The clinical association of intense cervical, dorsal or interscapular pain followed by a sensomotor deficit picture should lead to the suspicion of this entity, that would require an immediate examination with MRI to verify its diagnosis. Both the clinical manifestations as well as the characteristics observed by MRI of the NTSEH have a prognostic value and determine the therapeutic decision. (Author) 34 refs

    An 81-year-old man was found dead 1 month after he had disappeared following a visit to a hot spring resort in early autumn. The body showed severe postmortem changes with advanced skeletonization from the head to the abdomen as well as putrefactive and autolytic changes in the remaining tissues. The thoracic and abdominal organs had been lost. Naked eye examination revealed soft tissue injuries accompanied by ragged edges and characteristic punctures with no signs of vitality, suggesting that these injuries had been due to postmortem animal scavenging. However, bruises were prominent on the anterior parts of both lower extremities. Postmortem computed tomography (PMCT) scan demonstrated subdural hematoma over the right cerebral hemisphere, although the brain itself had undergone putrefactive and autolytic changes. Subsequent autopsy confirmed the presence of a 140 g acute subdural hematoma, which would likely have been fatal. This case illustrates that PMCT is able to yield important information about possible cause of death, even in a partially skeletonized body. PMID:23000271

    Dural arteriovenous fistula (AVF) presenting with subdural hematoma is relatively rare. We report a case of dural AVF presenting as acute subdural hematoma (ASDH) and provide a review of the literature. A 56-year-old man presented with disturbance of consciousness. Computed tomography demonstrated a right ASDH and a small right occipital subcortical hematoma. Cerebral angiography showed a dural AVF on the occipital convexity draining into the cortical veins. Emergent endovascular embolization was immediately performed and the shunt flow disappeared. Hematoma removal and external decompression were safely conducted. Combined therapy successfully recovered the patient's consciousness level. This rare case of dural AVF presenting with ASDH was treated with combined treatments of endovascular and open surgery.

    Full Text Available Aortic intramural hematoma frequently appear in elderly hypertensive patients who suffered a vasa vasorum rupture into the media, presenting clinical symptoms similar to aortic dissection. The current available data suggest a similar treatment strategy as in aortic dissection, although intramural hematoma is a different pathophysiological entity. The issue of the vulnerable contact of the intraaortic plaque, which is prone to rupture and to trigger the formation of an intramural hematoma, has not been elucidated so far. We present a brief literature review regarding complex plaque analysis, which opens a new area in identification of vulnerable patients with intramural hematoma, important for management of these patients and optimization of their treatment in order to avoid complications.

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

    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.

    While oral anticoagulants are associated with greater hematoma expansion and higher mortality rates in patients with intracerebral hemorrhage (ICH), there is ongoing discussion whether pretreatment with antiplatelet drugs also worsens prognosis. Using an experimental model of ICH, we investigated the effects of antiplatelet pretreatment on hematoma volume and functional outcome.

Se analizaron otras variables como: la situación topográfica, localización, desplazamiento de las estructuras de la línea media, estado neurológico del paciente y la técnica quirúrgica utilizada. Se demostró que a mayor volumen del hematoma, el deterioro neurológico fue mayor, así como la mortalidad. Se vio esta relación más marcada en los procesos agudos (48,6 %). La craneotomía demostró ser de más valor que la trepanación simple. Se concluye que el comando volumen de la TAC es un procedimiento de gran confiabilidad en la valoración neurorradiológica, terapéutica y pronóstica de los hematomas intracraneales postraumáticos. Abstract in english 35 patients with posttraumatic intracranial hematomas were studied from April, 1995, to February, 1997. These patients were diagnosed by computed axial tomography (CAT) and the volumen of the hematomas was calculated by software with the volume command. The result was compared with the average volum [...] e during surgery and no statistical difference was observed. Some other variables as the topographic situation, localization, displacement of the structures of the mean line, the neurological status of the patient and the surgical technique used, were analyzed. It was proved that the larger the hematoma volume was the higher the neurological deterioration and mortality were. This relationship was more significant in the acute processes (48.6 %). Craniotomy proved to have more value than simple trepanation. It was concluded that the volume command of the computed axial tomography is a very reliable procedure in the neuroradiological, therapeutic and prognostic assessment of posttraumatic intracranial hematomas.

  7. 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

METHODS: A total of 366 patients who underwent rhytidoplasty of at least the middle third of the face between July 2009 and September 2011 were included in the study. Group A was identified as the control group; it included the first 120 patients assessed retrospectively. The remaining 246 patients, who underwent the surgical procedure here proposed and who were evaluated prospectively formed group B. We observed the incidence of hematoma, ischemia, and necrosis in the first 72 postoperative hours. RESULTS: In group A, 17 (14.2%) patients developed hematomas, whereas none occurred in group B. The surgical procedure did not significantly increase the occurrence of ischemia: 11 (9.2%) patients in group A and 16 (6.5%) in group B had this complication (P

  11. 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)H. (author)

Descrição: apresenta-se um caso [...] clínico, com o devido enquadramento bibliográfico, de um doente do sexo masculino com 70 anos de idade e neoplasia prostática submetido a laminectomia de L2 com artrodese L1-L3 postero-lateral instrumentada por claudicação neurogénea devido a metástase de L2. No pós-operatório imediato instalou-se um quadro de défice neurológico progressivo com paraplegia flácida e necessidade de reintervenção para drenagem de hematoma epidural confirmado por Ressonância Magnética. O doente recuperou neurologicamente após a drenagem do hematoma tendo retomado as suas atividades de vida diária. Comentários: a maioria dos hematomas epidurais pós-operatórios em cirurgia da patologia raquidiana são assintomáticos. A necessidade de drenagem cirúrgica resume-se a 0,1 a 3% dos hematomas diagnosticados, sendo emergente após o início dos défices neurológicos. É necessário ter em atenção os fatores de risco para o desenvolvimento de hematoma epidural sintomático no pós-operatório imediato para antever a sua possibilidade.

Description: The authors present as clinical case a male patient ag [...] ed 70 years old with prostate cancer who underwent laminectomy of L2 and postero-lateral instrumented fusion of L1-L3 due to neurogenic claudication from L2 metastasis. In the immediate postoperative settled a progressive neurologic deficit with flaccid paraplegia and need for reoperation for drainage of epidural hematoma confirmed by MRI. The patient recovered neurologically after draining the hematoma having resumed their daily activities. Comments: Most epidural hematomas in postoperative pathology of spinal surgery are asymptomatic. The need for surgical drainage boils down to 0.1 to 3% of the hematomas diagnosed, being emergent after the onset of neurological deficits. Physicians must be aware of the risk factors for the development of symptomatic epidural hematoma in the immediate postoperative period to forecast its possibility.

    Subcapsular renal hematoma (SRH) after ureteroscopic lithotripsy (URSL) using holmium:yttrium-aluminum-garnet (Ho:YAG) laser to treat ureteric stones is a rare complication. We aimed to review our unit's experience of post-URSL subcapsular renal hematoma. From 2006 to 2012, 2059 URSLs using F9.5 rigid ureteroscope were performed in our unit. Patients with post-URSL symptomatic renal hematoma were reviewed. Perioperative information on patients' renal function, stone characteristics, and degree of renal hydronephrosis were reviewed. Operative data, postoperative information such as clinical manifestation, changes in blood parameters, CT findings, and subsequent treatment were documented. Of the 2059 patients treated with URSL and Ho:YAG laser, three patients were diagnosed as subcapsular renal hematoma after surgery; the age is 57, 61, and 63 years old, respectively. Preoperative imaging examination showed that two patients and one patient had obstructing middle and proximal ureteral stones ranging in size from 0.8 to 1.6 cm, and three patients had thin renal cortices. The double-J ureteral stents were inserted in all cases regularly. All three subcapsular renal hematoma patients had the loin pain of the operation side and fever, and one patient had significant hemoglobin drop (from 111 to 61 g/L) who need to transfusion. Two patients presented within 24 h of URSL, and one patient presented on day 10. One patient was treated conservatively for 3 weeks and recovered with bed rest, antibiotics, hemostasis, and analgesia with no intervention or drain. The other two patients underwent ultrasonography-guided drainage of the hematoma. Two-month follow-up CT scans or ultrasonography confirmed the resolution of the hematoma in all three cases. Renal subcapsular hematoma after URSL is a rare and one of serious complications. Subcapsular renal hematoma should be considered when patients have the symptoms of significant loin pain after URSL for obstructing ureteral stones with thin renal cortices. The treatment of post-URSL renal subcapsular hematomas needs to be customized for each patient. PMID:25943289

  15. Intrahemispheric subdural hematoma complicated with chronic neurologic diseases

    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.)

    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. This report will present the accomplishments and project highlights to date in the fiscal year 1999. Future project projections will also be discussed.

  3. Conditions supporting repair of potentially lethal damage cause a significant reduction of ultraviolet light-induced division delay in synchronized and plateau-phase Ehrlich ascites tumor cells

    International Nuclear Information System (INIS)

    Repair of potentially lethal damage (PLD) induced by uv light in synchronized and in plateau-phase cultures of Ehrlich ascites tumor cells was studied by measuring cell survival. In particlar the influence of conditions supporting repair of PLD on growth kinetics was investigated. In synchronized G1, S, or G2 + M cells as well as in plateau-phase cells, uv light induced, almost exclusively, delay in the next S phase. A significant decrease of this delay was observed when the cells were incubated for 24 hr in balanced salt solution. Repair of PLD after uv irradiation was found to occur in plateau-phase cells and in cells in different phases of the cell cycle provided that after irradiation these were kept under conditions inhibiting cell multiplication (incubation in balanced salt solution or in conditioned medium). The repair time constant t50 was significantly higher than those found for X irradiation (5-10 hr compared to 2 hr), and repair was not significantly inhibited by either 20 ?g/ml cycloheximide or 2 mM caffeine in 24 hr

    Amusement park ride injuries have been newsworthy events for many years. The multitude and severity of these injuries has been reported many times over the past 20 years and includes spinal cord and vertebral injuries, subarachnoid hemorrhage, internal and vertebral artery dissections, and even a few cases of subdural hematoma (SDH). There has also been as many theories to explain these injuries as there have been injuries themselves including how G forces and rotational acceleration can cause both neuroparenchymal and neurovascular injury.

    Full Text Available Background : Digital subtraction angiography (DSA and magnetic resonance angiography are the imaging modalities for the detection of intracranial arteriovenous malformations. However, these modalities are time consuming and cannot be used in emergency conditions. Computed tomography angiography (CTA has also been shown to reliably detect vascular disorders such as cerebral arteriovenous malformations (AVMs. Aims : The purpose of this study was to evaluate the usefulness CTA in the surgical treatment of AVMs and the hematoma evacuation. Patients and Methods : Case records of 18 patients with massive intracranial hematoma secondary to AVMs were retrospectively reviewed. All patients had emergent brain CT and CTA. Follow-up DSA was performed two to three weeks after surgery. The outcome was assessed using Glasgow Outcome Scale (GOS. Results : Emergent CTA demonstrated AVMs and defined the feeding arteries, abnormal vascular nest, and draining veins in all the patients. Fourteen patients underwent hematoma evacuation and total resection of the AVMs, and four patients had hematoma evacuation and a partial resection. Follow-up DSA demonstrated complete resection of AVM in 14/18 patients and partial resection in 4 patients. There were no deaths and none of the patients had rebleeding in the follow up. A GOS scores during follow-up were: GOS 3 in 12 patients, GOS 4 in 4 patients and GOS 2 in 2 patients. Conclusions : CTA can be a reliable and rapid diagnostic tool for detecting underlying AVM in patients presenting with intracranial hematoma and for the pretreatment planning of emergency craniotomy.

  6. 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)

  7. A Clinico-dynamic study of acute traumatic intracerebral hematoma by means of CT

    International Nuclear Information System (INIS)

    After the introduction of CT (HITACHI CT-H) in February, 1977, we have examined 11 cases of traumatic intracerebral hematoma (ICH). From the CT findings, including repeat CT scans within a short period, we have classified these cases into four groups. The first group included three cases whose CT revealed a large hematoma. The hematomas were removed immediately, obtaining good results. The second group included three cases whose initial CT revealed a small ICH, but whose repeat CT disclosed a large one, with a deterioration of the clinical state. They were operated on, with good results. The third group consisted of four cases whose ICH developed out of cerebral contusion. Three cases were diagnosed initially as cerebral contusion, but later CT scans revealed large hematomas within the contused areas. Two of them were operated on, with good results. The fourth group consisted of one case whose CT showed and ICH and a large chronic subdural hematoma (SDH). Most of his symptoms disappeared upon only the evacuation of the SDH. From these experiences, we realized especially that repeat CT scanning within a short period was extremely valuable for the management of an acute head injury when the patient became worse under conservative treatment.

    Spinal epidural hematoma (SEH) is an uncommon disorder, and chronic SEHs are rarer than acute SEHs. However, there is few reported involving the bone change of the vertebral body in chronic SEHs. We present a case report of lumbar epidural hematoma that required differentiation from extramedullary spinal tumors by a long process because the CT scan revealed scalloping of the vertebral body and review the relevant literature. A 78-year-old man had experienced a gradual onset of low back pain and excruciating pain in both legs. Lumbar MRI on T1-weighted images revealed a space-occupying lesion with a hyperintense signal relative to the spinal cord with no enhancement on gadolinium adminisration. Meanwhile, T2-weighted images revealed a heterogeneous intensity change, accompanying a central area of hyperintense signals with a hypointense peripheral border at the L4 vertebra. Moreover, the CT scan demonstrated scalloping of the posterior wall of the L4 vertebral body which is generally suspected as the CT finding of spainal tumor. During the epidural space exploration, we found a dark red-colored mass surrounded by a capsular layer, which was fibrous and adhered to the flavum and dura mater. Microscopic histological examination of the resected mass revealed a mixture of the relatively new hematoma and the hematoma that was moving into the connective tissue. Accordingly, the hematoma was diagnosed as chronic SEH. The particular MRI findings of chronic SEHs are helpful for making accurate preoperative diagnoses of this pathology. PMID:25130006

  9. 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 dadiologic diagnostic procedures for fast diagnosis of a retroperitoneal hematoma, abdominal CT-scan is the preferred method

    This study assesses the etiology, clinical management, and outcome of patients with spontaneous spinal epidural hematoma (SSEH). SSEH is an uncommon neurosurgical emergency. We analyzed data from 10 patients (six women, four men) treated for SSEH (mean age, 63.5 years). Five patients had bleeding disorders due to anticoagulant therapy at the time of diagnosis. The initial clinical symptom in most patients was severe pain (n=8). Spinal injury was assessed using the American Spinal Injury Association (ASIA) scale, with six Grade A, one Grade C, and three Grade D patients. Lesions were in the cervicothoracic (n=4), thoracic (n=5), and thoracolumbar regions (n=1). Location was dorsal in seven patients and ventral in three. SSEH extension ranged from three to 15 spinal levels (mean, 6.9 levels). ASIA scale outcomes for the entire group were Grade A, n=2; Grade B, n=1; Grade C, n=1; Grade D, n=2; and Grade E, n=4. Outcomes for patients with no bleeding disorders (n=5) were Grade D, n=1; and Grade E, n=4. Outcomes for patients with bleeding disorders (n=5) were Grade A, n=2; Grade B, n=1; Grade C, n=1; and Grade D, n=1. After surgical treatment, patients improved by at least by one ASIA grade. The patients with mild neurological deficit who were treated conservatively also improved. Emergent spinal cord decompression is the only way to preserve spinal cord function in patients with severe deficit. Coagulation disorders were related to poor neurological status at admission and with poor neurological outcome. Conservative treatment was acceptable in patients with minimal neurological deficit.

  13. Time Course of Early Postadmission Hematoma Expansion in Spontaneous Intracerebral Hemorrhage

    DEFF Research Database (Denmark)

    Ovesen, Christian; Christensen, Anders Fogh

    2014-01-01

    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.

    Born, Alfred Peter; Duno, Morten

    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.

    Full Text Available Traumatic subperiosteal hematoma (SpH usually presents late, after the initial trauma. It is generally seen in young males. Computed tomography is the best mode of imaging and helps to rule out orbital fracture or associated subdural hematoma. We present the clinical features and management of four patients seen at the orbit clinic with SpH. Management is based on time of presentation, visual acuity and any communicating bleed. The prognosis of traumatic SpH is excellent if treated with an individualized patient approach.

  18. Correlation of hyperdense and hypodense areas in the computerized tomogram of subdural hematomas

    International Nuclear Information System (INIS)

    CT findings of 51 patients with acute, subacute and chronic subdural hematomas were studied. The results showed that direct signs (hyperdensity, isodensity, and hypodensity) and indirect signs (midline-shift, expansive lesion, compression of ventricles, and occlusion of the subarachnoid space) can be distinguished. The following diagnostic procedure is proposed in cases of subdural hematoma: 1. In cases with both, direct and indirect CT signs, no further diagnostic exploration is necessary. 2. In cases without direct signs, application of contrast medium may lead to diagnosis. 3. Cases without direct or indirect signs showing clinical symptoms require further investigation by angiography, or CT control. (orig.)

    2011-01-01

    Background: Spontaneous acute subdural hematomas (SDHs) are rare. Risk factors for development of these hematomas include conditions such as hypertension, vascular abnormalities such as aneurysm or arteriovenous malformation, or consumption of anticoagulants. Case Description: Here, the authors report two patients who suffered from spontaneous acute SDH while taking fondaparinux for venous thromboembolism prophylaxis. One patient suffered from a remote episode of traumatic brain injury and underwent a decompressive craniectomy 3 weeks prior to presentation, whereas the other patient had been self-medicating with aspirin. Conclusion: To our knowledge, these two patients illustrate the first cases of spontaneous acute SDH formation most likely attributed to consumption of fondaparinux. PMID:21660271

  1. 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)

  2. Concurrent Delay in Construction Disputes

    DEFF Research Database (Denmark)

    Cavaleri, Sylvie Cécile

    2015-01-01

    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.

Debido a sangrado masivo en la intervención sin respuesta a la transfusión de hemoderivados, fue reexplorado en quirófano; ante la observación de sangrado difuso, se administró una dosis de factor VII recombinante activado. En el posoperatorio presentó elevación de presiones en la aurícula derecha, en la que se detectó compresión aislada por un hematoma; inicialmente se planteó una conducta conservadora. El paciente fue monitorizado mediante ecocardiograma transesofágico continuo y la conducta estuvo guiada por parámetros de llenado y función ventricular, además de la observación directa y continua del hematoma. 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.

  5. Hypertensive cerebellar hemorrhage and cerebellar hemorrhage caused by cryptic angioma

    International Nuclear Information System (INIS)

    A series of 44 patients with hypertensive cerebellar hemorrhage and nine patients with cerebellar hemorrhage caused by small angiomas is described. Hypertensive hemorrhage occurred most frequently in the patients in their seventies, whereas the onset of angioma-caused hemorrhage was often seen below the age of 40. Clinical syndromes of cerebellar hemorrhages can be categorized into three basic types: the vertigo syndrome, cerebellar dysfunction syndrome and brain stem compression syndrome. Patients with small (>= 2 cm in diameter in CT scans) and medium-sized (2 cm = 3 cm) hematomas deteriorated into unresponsive conditions and developed signs of brain stem compression. Surgical mortality was 32% in the hypertensive group, while it was 0% in the angioma group. Mortality as well as morbidity in both groups was strongly influenced by the preoperative status of consciousness. Our results suggest that substantial improvement could be obtained in the overall outcome of this disease by emergency craniectomy and removal of hematomas in all patients with large hematomas regardless of the levels of consciousness and regardless of the causes of bleeding. Furthermore, when clinical information and CT findings are suggestive of a ''cryptic'' angioma as the causative of a ''cryptic'' angioma as the causative lesion, posterior fossa surgery may be indicated to extirpate the lesion, even if the hematoma is small.

    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.

  8. 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 nce 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)

    2012-07-01

    Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

    Existing data on perfusion imaging assumes the perihemorrhagic zone (PHZ) in patients with intracerebral hemorrhage (ICH) to be size steady. This study investigates the size of the perihemorrhagic zone (PHZ) in patients with lobar ICH in relation to hematoma volume during the course of treatment using perfusion CT (PCT). The present analysis is based on a previously reported cohort of 20 patients undergoing surgical evacuation for lobar SICH, with pre- and early postoperative PCT scanning. Time to peak of the residue function (T{sub max}) was measured based on the 360 cortical banding method and singular value decomposition. The size of PHZ was determined before and after treatment and correlated with hematoma volume. Preoperative mean hematoma volume constituted 63.0 ml (interquartile ranges (IQR) 39.7-99.4 ml), which correlated significantly (r = 0.563, p = 0.010) with mean PHZ size (5.67 cm, IQR 5.44-8.17 cm). Following a surgical hematoma evacuation, mean hematoma volume was reduced to 2.5 ml IQR 0.0-9.5 ml, which also resulted in a significant reduction of PHZ size to 0.45 cm(IQR 0.0-1.36 cm; p < 0.001). There was no association between postoperative hematoma volume and size of the PHZ. Our findings illustrate that the extent of the PHZ cannot be generally assumed to be constant in size and that this differs significantly following hematoma reduction in patients with space occupying lobar SICH.

  18. Subperiosteal hematoma of the iliac bone: imaging features of acute and chronic stages with emphasis on pathophysiology

    International Nuclear Information System (INIS)

    The goal of this work is to describe the radiological appearance and clinical presentation of subperiosteal iliac hematoma and present a review of the literature. We retrospectively reviewed the radiological and clinical files of 19 patients (age range: 12-75; mean: 47) who presented with acute or chronic subperiosteal iliac hematomas. Imaging findings and relevant clinical information were recorded. A thorough literature search was performed to find additional cases of this rare condition. Three young patients presented with acute subperiosteal iliac hematoma following a fall. Clinical presentation was characterized by pain and gait disturbance presumed to result from crural nerve compression. Unilateral or bilateral lenticular hematomas deep in the iliacus muscle were demonstrated by CT for all patients while MRI was also available for two of them. In 16 asymptomatic patients, chronic ossified subperiosteal iliac hematomas were incidentally detected by CT. Progressive ossification of acute hematoma was demonstrated at follow-up in two patients. Subperiosteal iliac hematoma is rare but has typical imaging findings that may present acutely in adolescents or chronically in asymptomatic adults. (orig.)

  20. 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 thscan before therapy for individualized therapy. (authors)

    An objective of the study was to compare sensitivity of low- and extra high-field frequency magnetic resonance (MR) tomography of acutest intracerebral hematomas (ICH) and to assess differences between symptoms in obtained images. A study was conducted using experimental ICH in rats (n=6). Hematomas were formed by two injections of autologic blood into the brain. MR-devices "Bio Spec 70/30" with magnetic field strength of 7 T and "Ellipse-150" with magnetic field strength of 0,15 T were used in the study. MR-tomography was carried out 3-5 h after the injections. Both MR-devices revealed the presence of pathological lesion in all animals. Extra highfield frequency MR-tomography showed the specific signs of ICH caused by the paramagnetic effect of deoxyhemoglobin in T2 and T2*-weighted images (WI) and low frequency MR-tomography - in T2*-WI only. The comparable sensitivity of low- and extra high-field frequency MR-devices in acutest ICH was established. PMID:19770834

The day after admission the patient ran a fever of 38 ºC. Antiplatelet therapy was discontinued and lumbotomy and drainage of the hematoma was performed 7 days latter; about 400 mL of brownish blood was obtained. The patient progressed satisfactorily. It is concluded that spontaneous subcapsular renal hematoma is a rare complication of antiplatelet requiring multidisciplinary management.Computed tomography imaging is required for diagnosis. The renal compression due to its large size as well as pain and fever, justify their surgical drainage.

    The authors describe the clinical findings, radiographic appearance and surgical treatment of a spinal epidural hematoma (SEH) associated with spinal fracture in diffuse idiopathic skeletal hyperostosis (DISH). An 81-year-old male patient injured after falling from a 2.5 m tree presented with severe back pain. On plain radiographs and CT images, DISH with anterolateral osteophytes and fused thoracolumbar vertebrae was found along with a T12 fracture. Patient was initially treated with bed rest followed by placement into a body cast. Three weeks later, he presented with incomplete paraplegia of his lower limbs. CT images did not reveal any fracture displacement, but MRI images showed an epidural hematoma compressing the dura mater. The patient was successfully treated by posterior fixation surgery using pedicle screws and rod with vertebroplasty. We aimed to report a unique case of a SEH complicating a spinal fracture in DISH.

    Extracorporeal shock wave lithotripsy (SWL) is a very commonly used treatment modality for appropriate sized stones. Even though it is a noninvasive treatment technique, major complications may occur following SWL sessions. Herein, we report a 17-year-old male patient, who received 2 sessions of SWL treatment for his left kidney stone, 4 months before his admission. Imaging methods showed an enhanced left renal pelvis mass with contrast-enhanced computerized tomography (CT) and this finding raised a suspicion of pelvis renalis tumor. Diagnostic ureterorenoscopy was planned for the patient and operation revealed a left intrarenal hematoma, which was drained percutaneously during the same operation. Careful history should be taken from patients with renal pelvis masses and intrarenal hematoma formation should be kept in mind, especially if the patient has a previous SWL history. PMID:26064767

  1. Chronic subdural hematomas as evaluated by measns of SPECT, CT and EEG topography

    International Nuclear Information System (INIS)

    Nineteen patients with chronic subdural hematomas were reviewed, and, in an attempt to delineate the pathophysiology of this condition, evaluations were made by means of single-photon-emission tomography (SPECT), computed tomography (CT), and electroencephalographic (EEG) topography. Choronic subdural hematomas were classified into three types on the basis of their SPECT appearances: Type I: normal cerebral blood flow (CBF) in the basal ganglionic region, with or without a decreased mean cerebral hemispheric CBF on the affected side; Type II: decreased basal ganglionic as well as mean cerebral hemispheric CBF on the affected side; Type III: Diffuse, marked reduction of CBF on both sides. In 11 patients with headaches, the SPECT images were often classified as Type I, in which there was a normal regional CBF in the basal ganglia. In the majority, CT scans revealed either hypo- or iso-density in the lesions, with a minimal midline shift. No evidence of focal slow waves was seen on the EEG topograms. On the other hand, 6 patients with hemiparesis demonstrated, on their SPECT images, a relative reduction of both hemispheric and basal ganglionic CBF, as designated as Type II. CT showed high- or mixed-density, and focal slow waves were found on the EEG topograms. Subsequent measurements of the CBF after the evacuation of the hematomas in 13 patients disclosed a 10-20% increase in both hemispheric and basal ganglionic CBF, particularly in patients younger than 65. The presenly in patients younger than 65. The present clinical studies suggest a critical role of CBF, especially basal ganglionic CBF, in the pathophysiology of chronic subdural hematomas. (author)

  11. Prediction of prognosis in patients with epidural hematoma by a new stereological method

    International Nuclear Information System (INIS)

    Epidural hematoma (EH) is a serious clinical event observed in 2% of head trauma patients. Studies regarding the effects of epidural hematoma volume (EHV) on prognosis are not sufficient. In this study, we applied the volume fraction approach of the stereological method to estimate the hematoma to brain volume fraction (HBVF), and investigated the relation between the HBVF and prognosis. Fifty-nine EH patients (46 male and 13 female subjects, with average age of 21 years) admitted to the emergency clinic were included. The HBVF was estimated on the printed films of cranial computed tomography scans. For this purpose, common point counting grids were superimposed over the scan frames. According to the clinical results, patients were divided into three groups as complete recovery (43), disability (8) and exitus (8). The HBVF was compared with the clinical results. HBVF was determined as 4.6% in the patients with recovery, 8.1% in disability, and 7.6% in exitus patients. The HBVF values were lowest in recovery patients, and the difference between the recovery and the other two groups was statistically significant (p=0.007). However, there was no statistically significant difference in HBVF between disability and exitus patients (p>0.05). In conclusion, the HBVF can be an important tool to determine prognosis, and it can be measured using the volume fraction approach of stereological methods as developed in the present study.

  12. Effectiveness of Kampo medicine Gorei-san for chronic subdural hematoma

    International Nuclear Information System (INIS)

    Chronic subdural hematomas (CSDHs) are basically treated by surgery. In some cases with no or minimum symptoms, however, they may be treated conservatively. In the present study, we evaluated the therapeutic effect of a Kampo medicine (Japanese traditional herbal medicine), Gorei-san, in the treatment of those CSDHs. Gorei-san 7.5 g t.i.d. was orally administered for 4 weeks in 22 patients with 27 CSDHs. Maximum thickness of the hematoma was followed up on CT scan for 4 to 29 weeks after administration of Gorei-san. In 7 of 22 patients, tranexamic acid and/or carbazochrome sodium sulfonate were also administrated. Gorei-san was effective in 23 of 27 CSDHs. In 12 of them, the hematoma was completely disappeared within 14 weeks after administration. In the other 11 CSDHs, the thickness was decreased. In those effective cases, thickness began to decrease 3 to 4 weeks after administration of Gorei-san. It was more effective in CSDHs with iso-/high or mixed density than with low density on CT. It was not effective in 4 out of 27 CSDHs. No apparent adverse effect was noted in the present series of patients. The present study suggests that a Kampo medicine, Gorei-san, is a useful option in the conservative treatment of CSDHs with no or minimum symptoms. (author)

    Acute epidural hematoma (AEH), a relatively common complication of head injury in children, persists in bearing high morbidity and mortality. Early establishment of prognosis could guide optimal patient allocation, and early identification of predictive signs could assist in choosing appropriate therapeutic interventions. This study aimed to delineate expeditiously obtainable prognostic markers for determining outcome in a subset of children with AEH. We reviewed our 11-year experience with 61 consecutive children <16 years old with head trauma and isolated AEH. Treatment followed a standard advanced trauma life support protocol. A medical history was obtained, and all patients underwent neurosurgical and physical evaluations. CT scans were performed, as were laboratory tests which included arterial blood gases, glucose, electrolytes (K(+), Na(+)), hemoglobin and coagulation studies. Evaluation of the data collected on cause of injury, interval between trauma occurrence and presentation, clinical symptoms, Glasgow Coma Scale (GCS) scores, vital signs, laboratory test results, physical findings and surgical versus conservative management revealed that the best single predictors of outcome following AEH were the GCS and focal neurological deficits. Of all laboratory data obtained on admission, the blood potassium, pH and glucose test results correlated significantly with prognosis. Prognosis can be adequately and expeditiously estimated by selected markers within a comprehensive evaluation of children with AEH. PMID:11070432

A su ingreso presentó Glasgow inicial de 13 y diplopia por paresia del VI par derecho. En la TAC y RM cráneo-cervical se objetivó un hematoma subdural retroclival. Se realizó manejo conservador con colocación de collarín rígido. Se observó recuperación espontánea del VI par a los 6 días presentando únicamente cervicalgia al alta. Presentó resolución clínica y radiológica a los 3 meses del accidente. Conclusión: Las lesiones hemorrágicas retroclivales postraumáticas son típicas de la edad pediátrica por la inmadurez de la unión cráneo-cervical que presentan. El tratamiento de elección es la colocación de un collarín rígido aunque si existe progresión clínica puede ser necesaria la evacuación quirúrgica. Abstract in english Introduction: Retroclival posttraumatic hematomas are extremely rare and almost exclusive to childhood. Only one case of retroclival subdural hematoma has been reported in the literature to date. Case report: An 8-year-old boy suffered a severe head injury with cervical hyperextension as the result [...] of a bicycle accident. On admission his initial Glasgow Coma Score was 13 and he had diplopia due to right palsy of the VI nerve. A retroclival subdural hematoma was observed by CT and MRI of the craneovertebral junction. Management was conservative and a rigid collar was placed. Palsy of VI nerve recovered spontaneously at 6 days and at discharge the patient had only cervical pain. Follow up at 3 months after the accident showed clinical and radiological resolution. Conclusion: Traumatic retroclival hematomas are mainly a pediatric entity due to immaturity of the cranio-cervical junction. Treatment consists of placement of a rigid collar although clinical progression may require surgical evacuation.

  16. Possibility of the conservative management of acute epidural hematoma from the point of views of serial CT scan and the consciousness level

    International Nuclear Information System (INIS)

    Nowadays serial computerized tomography is often performed in the diagnosis and care of patients with acute epidural hematoma. In the treatment of acute epidural hematoma, serial computerized tomography has shown dynamic changes in the hematoma, and the careful observation of clinical signs has reduced the number of operative cases. Moreover, some good outcomes of cases of acute epidural hematoma have appeared as a result of conservative management. Since the introduction of computerized tomography, we have treated 79 cases of acute epidural hematoma. The mortality rate has been 12.7 % (10 cases), while there have been 60 good-outcome cases, including 22 non-surgical cases (27.8 %). In an attempt to make clear the possibility of the conservative management of acute epidural hematoma, we made a comparative study of surgical good-outcome cases and conservative good-outcome cases from the points of view of serial computerized tomography and the consciousness level. We reached the following conclusions: The guidelines for the conservative management of acute epidural hematoma are: 1) Glasgow coma scale: more than 14 points, 2) Volume of hematoma on CT: less than 20 ml, as determined by the volume-summation method, 3) No mass sign of hematoma on CT, 4) No or only transient forcal neurological signs, and 5) The above factors (1)-(4) have no tendency to get worse within 6 hours after head trauma.

    Objectives. Organized hematoma (OH) is a rare, nonneoplastic, hemorrhagic lesion causing mucosal swelling and bone thinning, mainly in the maxillary sinus. We aimed to clarify the clinical presentation and treatment of OH. Methods. Three cases of maxillary sinus OH and a literature review are presented. Results. Three men aged 16-40 years complained of nasal obstruction, frequent epistaxis, and/or headache. Clinical and radiological examinations revealed a maxillary sinus OH. They were cured in a piecemeal fashion via endoscopic middle meatal antrostomy. Furthermore, vascular endothelial growth factor and its receptor were expressed in the lesion. Conclusions. The pathogenesis of OH is unclear and it presents various histological and imaging findings; however, it is not difficult to rule out malignant tumors. Minimally invasive surgery such as endoscopic sinus surgery can cure it completely. Thus, it is important to determine the diagnosis using CT and MRI and to quickly provide surgical treatment.

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

  20. Does closed wound drainage really prevent epidural hematoma after lumbar surgery? Investigation upon postoperative magnetic resonance images

    International Nuclear Information System (INIS)

    In order to determine whether subfascial suction drains prevent epidural hematomas, 31 patients who underwent open lumbar discectomy or one-level decompression laminectomy were prospectively randomized with respect to each surgeon. The drain group (n=18) and the no-drain group (n=13) were comparable in regard to age, sex ratio, and preoperative coagulation indices. All patients underwent MRI the day after surgery and were evaluated for the presence of an epidural hematoma on axial T2-weighted images. All patients in both groups showed significant neurological improvement following surgery and there were no events suggestive of an epidural hematoma, such as intolerable pain or muscle weakness in the lower extremities. Although evidence of an asymptomatic epidural hematoma on the MRI scans was observed in a higher proportion of the patients in the drain group than in the no-drain group (54% vs. 17%), none of the patients who underwent open discectomy in either group were found to have evidence of a hematoma on their MRI scans. The results of the study suggested that suction drains are not required after open lumbar discectomy. (author)

  1. Complementary role of CT and In-111 leukocyte scans in the diagnosis of infected hematoma and thrombosis

    International Nuclear Information System (INIS)

    Patients with traumatic hematomas or those with indwelling catheters who subsequently develop fever and sepsis without clinical localizing signs to indicate an inflammatory focus can present a diagnostic dilemma. Early diagnosis of an infected hematoma or thrombus is important to optimal management. CT can provide, exquisite delineation of anatomy identifying and localizing a post-traumatic fluid collection but cannot reliably distinguish hematoma from abscess in all cases. A thrombus at a catheter tip may be too small to be resolved; when identified, the question of infection again remains. In-111 leukocyte scanning provides a method for identifying or ruling out infection in these situations. The authors performed In-111 leukocyte scans on 15 patients with indwelling catheters. Five of these patients were febrile with positive blood cultures. In-111 leukocyte scans showed positive findings in 8 patients: 5 showed surgically confirmed infected hematomas in the abdomen (3 in the pelvis, 1 in a kidney, 1 in the splenic bed), and 3 showed infected thrombosis in catheter tips. The authors conclude that CT scanning and In-111 leukocyte scanning play complementary roles in the evaluation of traumatic hematomas and thrombosis, the former providing precise anatomic delineation and the latter providing evidence of inflammation

    The purpose of this multicenter observational clinical study was to evaluate the performance of a near-infrared (NIR)-based, non-invasive, portable device to screen for traumatic intracranial hematomas. Five trauma centers collected data using the portable NIR device at the time a computed tomography (CT) scan was performed to evaluate a suspected traumatic brain injury (TBI). The CT scans were read by an independent neuroradiologist who was blinded to the NIR measurements. Of 431 patients enrolled, 365 patients were included in the per-protocol population analyzed. Of the 365 patients, 96 were determined by CT scan to have intracranial hemorrhages of various sizes, depths, and anatomical locations. The NIR device demonstrated sensitivity of 88% (95% confidence interval [CI] 74.9,95.0%), and specificity of 90.7% (95% CI 86.4,93.7%), in detecting the 50 intracranial hematomas that were large enough to be clinically important (larger than 3.5?mL in volume), and that were less than 2.5?cm from the surface of the brain. For all 96 cases with intracranial hemorrhage, regardless of size and type of hemorrhage, the sensitivity was 68.7% (CI 58.3,77.6%), and specificity was 90.7% (CI 86.4,93.7%). These results confirm the results of previous studies that indicate that a NIR-based portable device can reliably screen for intracranial hematomas that are superficial and of a size likely to be of clinical importance. The NIR device cannot replace CT scanning in the diagnosis of TBI, but the device might be useful to supplement clinical information used to triage TBI patients, and in situations in which CT scanning is not readily available.

  4. Evaluation of three imaging instruments in dogs with liver hematomas: concise communication

    International Nuclear Information System (INIS)

    Single-gamma emission computerized tomography (ECT) was compared with transmission computerized tomography (TCT) and scintillation-camera imaging (SC) in eight dogs with acute, solitary hematomas in the left liver lobe. The superior performance of TCT was attributed to its inherently better spatial resolution than those of ECT or SC, and to the fact that studies with TCT could be performed during apnea. ECT was more sensitive than SC to small changes in the spatial distribution of radionuclides. In addition, the ECT, by virtue of its sectioning capability, was more sensitive than is SC to differences in radionuclide concentrations at the same depth in an organ

  5. Intracranial hematoma and SAH: actual aspects in its interpretation with magnetic resonance

    International Nuclear Information System (INIS)

    A basic understanding of the magnetic properties of Hb degradation products explains the mechanisms and production of the signals occurring at the different stages of the formation and degradation of intracranial hematoma and SAH. Despite the interaction among complex phenomena and the fact that their explanations are not univocal, since many phenomena remain to be understood even in the light of those theories that, at present, most closely agree, the proposed models permit the comprehension and diagnosis of a pathology which, in addition to being common, is diagnostically relevant and serves as paradigm in Radiological research.

    Subarachnoid hemorrhage (SAH) volume was measured by three-dimensional computed tomography (3D-CT) and the correlation examined between the SAH volume and the occurrence of symptomatic vasospasm (SVS). Experimental (in vitro) hematomas were made with blood obtained from 10 volunteers. The hematoma volume was determined by actual measurements and by 3D-CT using a CT number in the range of 40-80 Hounsfield units (HU) on days 1, 4, 7, 11, and 14. The coefficients on days 1 and 4 were relatively high and the correlation between measured and estimated volumes was significant on days 7, 11, and 14. 3D-CT was also performed in 50 patients with SAH at onset (day 0) and on days 1, 4, 7, and 14. The hematoma volume including the volume of normal structures was automatically calculated (V1). The volume of normal structures (V2) with CT numbers of 40-80 HU was calculated in another 50 patients without intracranial lesions as 12 ml. The total hematoma volume was defined as V1 minus mean V2. The mean SAH volume was 44, 36, 21, 11, and 8 ml on days 0, 1, 4, 7, and 14, respectively. The hematoma volumes were significantly larger in patients with SVS than in patients without SVS at all time points. The minimum hematoma volume in patients with SVS was 92, 76, 42, 24, and 12 ml on days 0, 1, 4, 7, and 14, respectively. This method allows the quantitative determination of SAH volume based on 3D-CT, and may be useful in clinical studies of cerebral vasospasm. (author)l vasospasm. (author)

    Background The treatment of chronic subdural hematoma (cSDH) is still charged of significant risk of hematoma recurrence. Patient-related predictors and the surgical procedures themselves have been addressed in many studies. In contrast, postoperative management has infrequently been subjected to detailed analysis. Moreover variable intravenous fluid administration (IFA) was not reported in literature till now in the context of cSDH treatment. Methodology/Principal Findings A total of 45 patients with cSDH were operated in our department via two burr hole craniostomy within one calendar year. Downward drainage was routinely left in hematoma cavity for a one day. Independent variables selected for the analysis were related to various aspects of patient management, including IFA. Two dependent variables were chosen as measure of clinical course: the rate of hematoma recurrence (RHR) and neurological status at discharge from hospital expressed in points of Glasgow Outcome Scale (GOS). Univariate and multivariate regression analyses were performed. Hematoma recurrence with subsequent evacuation occurred in 7 (15%) patients. Univariate regression analysis revealed that length of IFA after surgery influenced both dependent variables: RHR (p?=?0.045) and GOS (p?=?0.023). Multivariate regression performed by backward elimination method confirmed that IFA is a sole independent factor influencing RHR. Post hoc dichotomous division of patients revealed that those receiving at least 2000 ml/day over 3 day period revealed lower RHR than the group with less intensive IFA. (p?=?0.031). Conclusions/Significance IFA has been found to be a sole factor influencing both: RHR and GOS. Based on those results we may recommend administration of at least 2000 ml per 3 days post-operatively to decrease the risk of hematoma recurrence. PMID:22532865

    Uremia associated with anticoagulant therapy is a high risk factor for bleeding complications in patients undergoing hemodialysis. We report a case of intrarenal hematoma arising in a uremic patient treated with warfarin. The hematoma was rapidly diagnosed by ultrasonography of the abdomen and treated with embolization. Our experience confirms that the availability of an ultrasound facility within the renal unit allows better assessment of our patients, also in the management of the most fearsome and rare complications. Moreover, it strengthens the evidence that uremic patients are at high risk of bleeding complications when treated with oral anticoagulants. PMID:23117741

  9. Serious clopidogrel associated renal hematoma in a type 2 diabetic patient with primary hyperparathyroidism after extracorporeal shock wave lithotripsy

    International Nuclear Information System (INIS)

    Renal hematoma after extracorporeal shock wave lithotripsy SWL is a rare complication. We report a case of a large renal hematoma following SWL that resulted in nephrectomy in a type 2 diabetic patient with primary hyperparathyroidism using clopidogrel due to coronary heart disease CHD. Although it was claimed that preoperative use of clopidogrel was not associated with increased bleeding, all patients who are scheduled for SWL should be interrogated in terms of using of platelet aggregation inhibitors such as clopidogrel, and these drugs should be interrupted appropriately before undergoing SWL.

    Fondaparinux is an accepted form of deep venous thrombosis prophylaxis after hip arthroplasty. Cited advantages of its use include once-daily administration, standard dosage, and superiority as compared with enoxaparin. However, there have been several case reports of serious associated bleeding complications. We describe the case of a 77-year-old woman who developed a massive leg hematoma in the operative extremity nearly 3 weeks after a primary total hip arthroplasty while on fondaparinux. The patient developed a compartment syndrome requiring decompression of the hematoma, fasciotomy, and subsequent additional plastic surgery for split thickness skin grafting. PMID:22177799

  11. Moessbauer study of the time evolution of the biochemical composition of the hematomas. Relationship with magnetic resonance imaging (MRI)

    International Nuclear Information System (INIS)

    Biochemical constitution of the hematoma is depending of its evolution. In order to obtain a reliable diagnostic of the NMR images in case of vascular accidents, a systematic study of the time-evolution of hematomas has been performed, using Moessbauer spectrometry and complementary technics (ESR and visible absorption spectrophotometry). The change, in the course of time, of HbO2 in deoxyhemoglobin Hb and other denaturation products (MHb, hemi- and hemochromes, ...) are well-recognized on the different spectra. T1 and T2 NMR relaxation times are measured in the same time and their shortening is related to the appearance of the paramagnetic denaturation blood compounds. (orig.)

    Full Text Available Abstract We described a 6 years follow-up of a spontaneous aortic intramural hematoma (IMH with cardiovascular magnetic resonance (CMR examination. Since multiple factors may play roles in the natural history of IMH, the patient experienced the course of progression, which included hematoma absorption, ulcer-like lesion, aneurysm and limited dissection. The initial and follow-up CMR examination included 3D CE MRA and non-enhanced "bright blood" pulse sequence. The inherent advantage of outstanding contrast with plain scan, which shorten the scan time and avoid potential risk of contrast agent, might make the fast gradient echo sequence as an alternative method when following stable IMH.

    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.

    Full Text Available Delay devices are used to perform various roles like aiding in sequential release of payload, providing safety in flight/ trajectory, enabling self-destruction of ammunitions, allowing blast of the warhead after penetration in runway/bunker, etc. The delay time is introduced to cause a series of detonation events from the explosive charge, in order to achieve desired efficiency. Inspite of many improvements performed along the years, in search of precise delay compositions, it is noticed that the obtained accuracy in chemical delay compositions is of ±4%.The present work using microcontroller gives possible accuracy of upto ±1%.This paper discusses about programmable electronic delay device, timing accuracy of electronic delay device and its merits over chemical delay devices.Defence Science Journal, 2013, 63(3, pp.305-307, DOI:http://dx.doi.org/10.14429/dsj.63.2880

    In daily operation, railway traffic always deviates from the planned schedule to a certain extent. Primary initial delays of trains may cause a whole cascade of secondary delays of other trains over the entire network. In this paper, we propose a stochastic model for delay propagation and forecasts of arrival and departure events which is applicable to all kind of public transport (not only to railway traffic). Our model is fairly realistic, it includes general waiting policies (how long do ...

  17. Predictive value of small ulcers in the evolution of acute type B intramural hematoma

    International Nuclear Information System (INIS)

    Objective: To assess the long-term evolution and predictive factors of type B intramural hematoma (IMH). Material and methods: 34 patients (33 men), mean age: 67 years (47–87) diagnosed with type B IMH by computed tomography (CT) and followed up clinically and by CT yearly. Mean follow-up was 5.9 years (2–13 years). Two evolution patterns were considered: (a) regression and (b) progression. Clinical and imaging variables were analyzed for assessing their predictor values. Results: Evolution at one year was to regression in 56% and to progression in 44% of cases. There were no association among age, sex, other aortic abnormalities, presence of atherosclerotic disease or blood pressure, initial maximum aortic diameter, indexed maximum aortic diameter, IMH thickness or length, presence or absence of mediastinal hematoma and the evolution of type B IMH. Ten patients had small aortic ulcers in the acute phase. The presence of ulcers was related with progression of IMH. No differences were observed in evolution between the control at first year and the last control. Conclusions: The presence of small ulcers is a strong predictor of evolution in acute type B IMH. In addition, the regression group remains completely stable after the first year of evolution.

  18. Acute traumatic subdural hematoma in infancy and childhood classification and treatment from CT findings

    International Nuclear Information System (INIS)

    Acute traumatic subdural hematoma in infancy and childhood has much difference from that in adult on their symptom, clinical course, and indication of surgical treatment. The aim of this study is to examine their clinical course and CT findings just after the injury and to evaluate the treatment modality for types of complex this disease. As the result of these examination, SDH patients are divided into five categories in account of their CT findings, especially according to the relationship between the hemispheric swelling and the amount of SDH. Simple SDH type shows classical clinical course and surgical treatment are frequently essential in rapidly progressive cases. Isodensity hemispheric swelling (IHS) type is more frequently seen in CT findings which shows thin SDH and prominent brain swelling. This IHS (a subtype of diffuse brain injury) type should be recognized for their favourable outcome under conservative treatment. Other three types are; contusion with SDH, acute excerbation of chronic SDH, and battered child. Indication of surgical treatment will be decided considering to the volume of hematomas. (author)

  19. Surgical treatment of progressive ethmoidal hematoma aided by computed tomography in a foal

    International Nuclear Information System (INIS)

    A progressive ethmoidal hematoma (PEH) was treated successfully in a 4-week-old Belgian filly by surgical removal, using a frontonasal bone flap. The filly had respiratory stridor, epistaxis, and facial enlargement over the left paranasal sinuses, which had progressively increased in size since birth. Computed tomographic images of the head obtained with the foal under general anesthesia were useful in determining the extent and nature of the soft-tissue mass and planning surgical intervention. On the basis of the histologic appearance of the mass, a diagnosis of PEH was made. Twelve months after surgery, the facial appearance was normal and the abnormal appearance of the ethmoid region on endoscopic evaluation was less obvious, with return of the nasal septum to a normal position. Progressive ethmoidal hematoma is uncommon and, to our knowledge, has not been reported in a neonate. Clinical signs of PEH in this foal were atypical because of the rapid enlargement of the mass, extent of facial deformity, and minimal epistaxis and interoperative hemorrhage

    Full Text Available This study investigates the causes of delay of building construction projects in Ghana to determine the most important according to the key project participants; clients, consultants, and contractors. Thirty-two possible causes of delay were identified from the literature and semi-structured interviews of 15 key players in the implementation process. These delay factors were further categorised into nine major groups. The list of delay causes was subjected to a questionnaire survey for the identification of the most important causes of delay. The field survey included 130 respondents made up of 39 contractors, 37 clients and 54 consultants. The relative importance of the individual causes and the groups were calculated and ranked by their relative importance index. The overall results of the study indicate that the respondents generally agree that financial group factors ranked highest among the major factors causing delay in construction projects in Ghana. The financial group factors were delay in honouring payment certificates, difficulty in accessing credit and fluctuation in prices. Materials group factors are second followed by scheduling and controlling factors.

    Full Text Available Introduction & Objective: Among all of the neurologic diseases in adult life, the cerebrovascular disease (CVD is the most common and important ones. Intracerebral hemorrhage (ICH in basal ganglia (BG is one of the common and major types of CVD. The relations between clot size and mortality rate, in different parts of the brain, has been addressed by several researchers. It is unclear whether such a relationship is in BG. Therefore this study was designed to find a formula that predicts outcome of hemorrhage based on clot size in BG.Materials & Methods: This descriptive-comparative study that was carried out prospectively, conducted on all 63 patients who admitted to the hospital during one year, with definite diagnosis of ICH in BG. After urgent CT scanning, the size of hematoma was determined by scan images. Routine treatment was uniform for all patients. Focal signs and consciousness state were assessed in the first and last days of admission. The data were analyzed using descriptive statistics, frequency tables and chi-square and T- test. Results: 33% of patients died. Hematoma size in 70% of them was larger than 5cm and in other 30% smaller. None of the hematoma with less than 4cm size was fatal. In patients with clots of 5cm or larger, the mortality was 100%. Conclusion: The results indicated that, there was meaningful relationship between hematoma size and mortality, in BG hemorrhages. So the clot size can be used as a factor in predicting hemorrhage outcome in BG.

Although the pathogenesis of CSDH associated with ACs remains unknown, several possible mechanisms have been proposed. In many reported cases, the patients with ACs in the middle fossa would be symptomatic according to development of CSDH. A 9-year-old girl presenting with a headache, nausea, and diplopia was referred to our department. Magnetic resonance imaging showed an AC in the left-side middle fossa and ipsilateral CSDH with a remarkable mass effect. Irrigation of the CSDH, partial removal of the outer membrane of the AC and CSDH, and endoscopic cystocisternostomy were performed to relieve her symptoms. Postoperative clinical course was excellent. Histopathological examination of the outer membrane of the CSDH demonstrated an arachnoid cell layer and hemorrhage from the granulation inside the membrane, and collagen fibers outside the membrane. These findings strongly suggested that the membrane and the content of the CSDH were derived from the outer membrane of the AC, and the CSF including the hemorrhage within the membrane, respectively. Laceration and hemorrhage from granulation tissue within the outer membrane of the AC are considered as one of the developmental mechanisms of the CSDH associated with AC in the middle fossa.

    The development of subarachnoid hemorrhage (SAH) following evacuation of chronic subdural hematoma (CSDH) is a very rare phenomenon. SAH in this context occurring secondary to intracranial aneurysm rupture is still rare. We report a case of an elderly lady who presented with right hemiplegia and altered sensorium. Computed tomography (CT) scan of the brain revealed a left fronto-temporoparietal CSDH with midline shift, which was promptly evacuated surgically via a single burr-hole. Postoperatively, her level of consciousness deteriorated and there was increased the amount of drain. Emergency CT of the brain revealed diffuse SAH. CT cerebral angiogram revealed one aneurysm each in the right internal carotid artery and anterior communicating artery. Meanwhile, her consciousness level improved on conservative management. The relatives were not keen for further follow-up. PMID:25972954

    Full Text Available A 62-year-old male patient was admitted to our hospital due to severe chest pain, odynophagia, and hematemesis. Chest computed tomography showed an esophageal submucosal tumor. Esophagogastroduodenoscopy (EGD revealed a longitudinal purplish bulging tumor of the esophagus. Endoscopic ultrasound (EUS showed a mixed echoic tumor with partial liquefaction from the submucosal layer. The patient was diagnosed with esophageal intramural hematoma as well as achalasia by upper gastrointestinal endoscopy, esophagography and esophageal manometry. The patient was managed conservatively with intravenous nutrition, and oral feeding was discontinued. Follow-up EGD and EUS showed complete recovery of the esophageal wall, and finally, the patient underwent endoscopic dilatation for achalasia. The patient was symptom free at the time when we wrote this manuscript.

    Full Text Available Diaphragmatic injury following blunt thoracoabdominal trauma is rare and is usually associated with key radiological features like dependent viscera sign, collar sign, diaphragmatic thickening and defects. It may also be associated with secondary signs like intrathoracic herniation of abdominal viscera. Diaphragmatic crura, which are attached to the upper lumbar vertebra represent prominently thickened folds along the posterior diaphragm, are usually inconspicuous on routine Computed Tomography (CT scans. We present a case of a young patient who sustained a motor vehicle accident and developed difficulty in breathing. CT scan of the patient revealed bilateral crural hematomas, with splenic and renal lacerations and no other sign of diaphragmatic injury. The patient was operated and blunt diaphragmatic rupture was confirmed at surgery.

  12. Dynamic MRI study for hematoma and hemangioma with inversion recovery snapshot FLASH method

    International Nuclear Information System (INIS)

    We studied 38 patients with liver tumor using inversion recovery snapshot FLASH (turbo-FLASH) (16 hepatomas, 7 hemangiomas) and FLASH (12 hepatomas, 3 hemangiomas) on dynamic MRI study. Hematomas showed central enhancement on early phase, and their maximum intensities were recorded on early phase by turbo-FLASH (12/12, 100%) and FLASH (7/12, 58.3%) respectively. Hemangiomas showed peripheral enhancement on early and mid phases, and their maximum intensities were recorded on mid or late phase by turbo-FLASH (6/7, 85.7%) and FLASH (3/3, 100%) respectively. Turbo-FLASH dynamic MRI study is useful for differentiation between hepatoma and hemangioma. (author)

    Group Delay variations versus frequency is an essential factor which can cause distortion and degradation in the signals. Usually this is an issue in wideband communication systems, such as satellite communication systems, which are used for transmitting wideband data. However, group delay can also become an issue, when working with high Q antennas, because of the steep phase shift over the frequency. In this paper, it is measured how large group delay variations can become, when going from a low Q antenna to a high Q antenna. The group delay of a low Q antenna is shown to be around 1.3 ns, whereas a high Q antenna has group delay of around 22 ns. It is due to this huge group delay variation characteristics of high Q antennas, that signal distortion might occur in the radio system with high Q antennas.

    The aim of the study was to evaluate the factors that act as barriers and delay the process of cochlear implantation in children with congenital profound sensorineural hearing loss. This is a cross sectional observational study in which 154 children with profound sensorineural deafness attending ENT outdoor from Jan 2013 to June 2014 at Sri Aurobindo Institute of Medical College and PG Institute, Indore, were included in the study. Information was taken from the parents of the candidates regarding the reasons for the delay in reporting, the delay in intervention and a detailed history was also taken to evaluate the possible reason for the hearing loss with the help of open ended questions. The most common cause for the delay in reporting was lack of information about the availability of technique and procedure for cochlear implant. Financial constrain was the most common cause for the delay in getting the cochlear implant surgery. PMID:26075172

    Optical variable delay devices for providing variable true time delay to multiple optical beams simultaneously. A ladder-structured variable delay device comprises multiple basic building blocks stacked on top of each other resembling a ladder. Each basic building block has two polarization beamsplitters and a polarization rotator array arranged to form a trihedron; Controlling an array element of the polarization rotator array causes a beam passing through the array element either going up to a basic building block above it or reflect back towards a block below it. The beams going higher on the ladder experience longer optical path delay. An index-switched optical variable delay device comprises of many birefringent crystal segments connected with one another, with a polarization rotator array sandwiched between any two adjacent crystal segments. An array element in the polarization rotator array controls the polarization state of a beam passing through the element, causing the beam experience different refractive indices or path delays in the following crystal segment. By independently control each element in each polarization rotator array, variable optical path delays of each beam can be achieved. Finally, an index-switched variable delay device and a ladder-structured variable device are cascaded to form a new device which combines the advantages of the two individual devices. This programmable optic device has the properties of high packing density, low loss, easy fabrication, and virtually infinite bandwidth. The device is inherently two dimensional and has a packing density exceeding 25 lines/cm.sup.2. The delay resolution of the device is on the order of a femtosecond (one micron in space) and the total delay exceeds 10 nanosecond. In addition, the delay is reversible so that the same delay device can be used for both antenna transmitting and receiving.

    Full Text Available Objective To investigate the clinical efficacy of two surgical approaches, trans-sinus small-window craniotomy (TSSWCT and combined supratentorial-infratentorial craniotomy (CSITCT, on non-progressive trans-sinus epidural hematoma.  Methods There were 67 patients with non-progressive trans-sinus epidural hematoma who underwent TSSWCT or CSITCT. The postoperative residual hematoma, postoperative alteration of intracranial pressure (ICP, recanalization of affected cerebral venous sinuses, length of hospitalization, and 6-month Glasgow Outcome Scale (GOS score of patients were retrospectively compared.  Results Compared with patients in the CSITCT group (N = 35, those in the TSSWCT group (N = 32 had significantly reduced postoperative residual hematoma near the venous sinus [(1.40 ± 1.60 ml vs (3.50 ± 2.10 ml, P = 0.000], length of hospitalization [(13.40 ± 5.70 d vs (17.30 ± 7.00 d, P = 0.015], markedly down-regulated levels of intracranial pressure (ICP at indicated postoperative time points [1 d: (164.40 ± 33.30 mm H2O vs (198.60 ± 49.30 mm H2O, P = 0.002; 3 d: (185.90 ± 47.80 mm H2O vs (226.30 ± 81.60 mm H2O, P = 0.017; 7 d: (154.70 ± 52.50 mm H2O vs (198.30 ± 84.20 mm H2O, P = 0.014], and distinctly improved recanalization of affected cerebral venous sinuses (87.50% vs 65.70% , P = 0.037. Moreover, the 6-month GOS scores were not statistically different between patients in 2 groups (Z = -0.114, P = 0.909.  Conclusions Compared with CSITCT, TSSWCT is a reliable surgical approach in the treatment of non-progressive trans-sinus epidural hematoma which has strengthened capability of evacuating hematoma underlying affected venous sinuses, relieving the compressed venous sinus and attenuating the intracranial hypertension. DOI: 10.3969/j.issn.1672-6731.2015.02.011

    Full Text Available Objetivo: Determinar la prevalencia de los hematomas renales postlitotricia en nuestra unidad, la incidencia de los sintomáticos y/o progresivos, el comportamiento clínico, el manejo de los mismos, así como los factores potencialmente influyentes sobre dichos aspectos. Método: Estudio observacional [...] prospectivo en el que analizamos diversos parámetros integrados en nuestra base de datos a partir de hojas recopilatorias confeccionadas en 314 pacientes sometidos a litotricia sobre 324 unidades renales en igual número de sesiones. Para el análisis estadístico se utilizó el paquete SPSS 15.0 con la asesoría de especialistas en bioestadística. Para el diagnóstico de los hematomas se utilizaron datos clínicos (interrogatorio y exploración física), hematológicos y ecográficos, estos últimos en casos aislados complementados con TAC, se realizó seguimiento mediante contacto telefónico con los pacientes durante un periodo de tiempo comprendido entre los 7 y los 19 meses después de la litotricia. Resultados: La prevalencia de hematomas fue del 13% pero sólo el 6,2 % fueron sintomáticos, la incidencia acumulada de hematomas de evolución progresiva fue de el 2,16 % y en el 0,92 % de las litotricias se requirió transfusión sanguínea a causa de los hematomas, lo que representó el 7,14% de estos. Los factores estadísticamente asociados a la incidencia de hematomas fueron el número de onda (superior a 2300), la energía total (a partir de 150J), el KV (a partir de 17,5), la microhematuria preoperatoria, la hipertensión perioperatoria, la litiasis de cistina, el hidrocáliz, la localización calicial del cálculo, (principalmente inferior), la asociación de cardiopatía isquémica con hipertensión arterial, (HTA) o hepatopatías, las hepatopatías crónicas "per se", la elevación de transaminasas, el uso habitual de antiagregantes plaquetarios y AINEs (sobre todo con pauta previa de heparina fraccionada para la progresión de los hematomas) y la combinación de estos con HTA pre-operatoria (para los hematomas síntomáticos), así como la presencia de litiasis múltiple tratadas en la misma sesión, encontrándose grados de asociación diferentes para los distintos subgrupos de hematomas establecidos. Se observó diferencias en el comportamiento clínico de los tipos de hematomas (subcapsular y perirrenal) y el 12 % de los pacientes con hematomas permanecieron sintomáticos entre 2 y 6 meses después. Conclusiones: El hematoma renal postlitotricia es mas frecuente de lo que creemos; su magnitud y evolución variables dependen de múltiples factores, algunos de los cuales tienen mayor peso específico (hepatopatías, comportamiento de la tensión arterial perioperatoria y uso habitual de fármacos antiagregantes con necesidad de heparina fraccionada perioperatoria), lo que dió lugar a pacientes con mayor riesgo de presentar hematomas cuando concurrieron 3 o mas de los factores relacionados encontrados en la presente serie. Los hematomas subcapsulares y los perirrenales difieren en su comportamiento clínico. Los hematomas con diámetros ecográficos iniciales igual o mayores de 4 cm fueron mas propensos a la progresión. El riesgo de expresión sintomática o de progresión de un hematoma se evidenció en los primeros cinco días postlitotricia aún cuando permanecieran asintomáticos o estables clínica e imagenológicamente en las primeras 24 hrs., todo lo cual aconseja un seguimiento cuidadoso y reposo físico relativo durante la primera semana en los pacientes con mayor riesgo, y considerar el reposo al menos cinco días en todos los pacientes tratados, entre otras medidas. El dolor lumbar puede persistir hasta seis meses en algunos pacientes después de padecer un hematoma postlitotricia clínicamente significativo.

    Calcified chronic subdural hematomas after shunting procedures for treatment of hydrocephalus have been rarely described. When the calcified wall is so large to extensively cover the surface of the cerebral hemispheres, this instance has been defined "Armored Brain". The Authors report the case of an eleven-year-old patient affected by triventricular hydrocephalus due to aqueductal stenosis, that was treated by a ventriculoatrial shunt. The post-operative course was uneventful and the patient recovered completely from the preexisting neurological deficits. Nevertheless, a CT scan performed 2 and 1/2 years later, revealed the development of a bilateral calcified chronic subdural hematoma, to such extent to configure a so-called "Armored Brain". Clinical course, pathogenesis and treatment of such kind of pathology are discussed in light of the data reported from the literature. PMID:3668658

  3. Delayed gamma rays

    International Nuclear Information System (INIS)

    Delayed gamma ray radiation is that component of initial nuclear weapon radiation emitted within the first 60 seconds following initiation by products of fission and of neutron activation that are parts of the debris of the nuclear explosion. The debris initially resides within the fireball, a luminous sphere of hot gases generated by the interaction with the air of X rays radiated from the hot debris within a millionth of a second after initiation. The fireball also defines the edge of a region of very low density air created by the expansion of the very hot gases within. The high pressure region created at the edge of this density well forms the shock wave that breaks away from the fireball and travels outward, superimposed on the ambient air. The net effect of these perturbations is to decrease the amount of air on a line from the source to a target, thereby enhancing the transmission of delayed radiation over that which would occur in unperturbed air. This effect is often referred to as hydrodynamic enhancement. The density well is buoyant and begins to rise within a fraction of a second of its creation. Its momentum is augmented by returning shock wave, now reflected off the ground. The rise of the fireball, which includes the radiation source, causes the distance between source and target to increase, thereby causing the radiation transmission to decrease once the expansion of the fireball has slowed or stopped. As the fireball rises the outer surface cools and ireball rises the outer surface cools and is subject to drag forces from the surrounding atmosphere. The drag causes the spherical fireball to become a toroidal cloud of condensed gases, containing the weapon debris. Throughout this process, the weapon debris, including the fission products, are in motion relative to the fireball. First, the debris are propelled toward the top of the fireball with an initial impulse provided by the reflected shock. Eventually the debris pierce the top of the rising fireball and flow down the side, with most becoming incorporated in the torus or in the cloud skirt below the torus. These effects become less pronounced as the scaled burst height increases, where the scaled burst height is defined to be the burst height divided by the yield to the one-third power (HOB/y1/3). This complex system, consisting of a radioactive, hence time-varying, source of gamma rays and similarly time-varying geometry, in which the amount of air between source and target is changing even as the source rises from its original location, must be modeled in some detail to describe properly the intensity of the delayed radiation component. The motive for doing so is that the delayed gamma radiation produces on the order of half the gamma-ray dose at Hiroshima and Nagasaki. Three technical areas must be addressed in the modeling process. They are: 1) the fission product gamma-ray source, 2) gamma-ray transport, and 3) nuclear-weapon hydrodynamics. Data required for modeling the processes of interest in these areas have been acquired through laboratory and field measurements. However, these data are by no means complete. Here follows a discussion of such modeling as it affects the prediction of A-bomb survivor dose as computed using the 1986 Dosimetry System for Japanese A-bomb survivors (DS86)

    Full Text Available Introduction. Retroperitoneal hematoma may occur as a result of trauma, but also from rupture of arterial aneurysms (aortic or iliac, surgical complications, tumors or anticoagulation therapy. Case report. We presented a patient on permanent anticoagulation therapy. On the day of admission to our institution, the patient had the value of his INR 5.57 which required immediate suspension of the therapy. The main symptom in this patient was pain in the right inguinal canal with propagation along the right leg, which was indicated in clinical picture of spontaneous retroperitoneal haematoma. After three days the fall of hemoglobin occurred, so the additonal diagnostics was done. A computed tomography of the abdomen was performed showing well limited, large retroperitoneal hematoma (213 x 79 x 91 mm. Transfusion of concentrated red blood cells was performed twice with satisfactory correction of hemoglobin level, and four units of fresh frozen plasma. The patient was hemodynamically stabilized and discharged after a two-month long intensive care unit treatment, with the advice to use low-molecular weight heparin 2 x 0.4 mg subcutaneusly, due to persistent arrhythmia. Conclusion. In patients on anti-coagulation therapy regular monitoring of the anticoagulant status is extremely important, because of the possibility of fatal complications development, such as retroperitoneal hematoma.

    Full Text Available The evaluation of the patients who will be operated in terms of preoperative bleeding diathesis is an obligation. This evaluation contains history, physical examination and tests of haemostasis. That are as a routin used among these tests are the number of platelet, PT, aPTT and the values of INR. Despite these assessments,all of the bleeding-clotting disorders have not been able to be determined. Therefore, due to omitted diagnosis of bleeding diathesis, in orthopedic procedures, hemartroz hemarthrosis, intramuscular hematoma, and abandoned bleeding may develop in the postoperative period. These complications are the causes of morbidity and mortality. In one of our cases, who had osteochondroma in his femur diaphysis and also whose preoperative history, examination and mentioned tests were normal, developed recurrent bleeding and hematoma in the operative area in the postoperative period. Von Willebrand disease was determined in the examination which was carried out by being considered bleeding diathesis. As a result, seen at the rate of 1% in community screening and the most common inherited bleeding diathesis, in the cases of Von Willebrand disease’s subclinical a good patient history should be taken in order to be able to be early dianosed diagnosed and to be able to be prevent the complications and also the necessary tests for diagnosis should be performed.

    Delay discounting describes the decline in the value of a reinforcer as the delay to that reinforcer increases. A review of the available studies revealed that steep delay discounting is positively correlated with problem or pathological gambling. One hypothesis regarding this correlation derives from the discounting equation proposed by Mazur (1989). According to the equation, steeper discounting renders the difference between fixed-delayed rewards and gambling-like variable-delayed rewards larger; with the latter being more valuable. The present study was designed to test this prediction by first assessing rats’ impulsive choices across four delays to a larger-later reinforcer. A second condition quantified strength of preference for mixed- over fixed-delays, with the duration of the latter adjusted between sessions to achieve indifference. Strength of preference for the mixed-delay alternative is given by the fixed delay at indifference (lower fixed-delay values reflect stronger preferences). Percent impulsive choice was not correlated with the value of the fixed delay at indifference and, therefore, the prediction of the hyperbolic model of gambling was not supported. A follow-up assessment revealed a significant decrease in impulsive choice after the second condition. This shift in impulsive choice could underlie the failure to observe the predicted correlation between impulsive choice and degree of preference for mixed- over fixed delays. PMID:21352902

    Full Text Available PURPOSE: Hypertensive cerebral hemorrhage in the basal ganglia is a potentially life-threatening cerebrovascular disease with high mortality. Surgical evacuation is an important treatment for intracerebral hemorrhage. However, little is reported about the comparison on the efficacy of various approaches on the prognosis. METHODS: Clinical data of 80 cases of intracerebral hemorrhage which surgically treated via transsylvian-transinsular approach or transcortical-transtemporal approach were collected. The proportion of post-surgery tracheostomy, incidence of digestive tract hemorrhage, revision surgery, the average length of hospital stay, and the six-month efficacy (defined by an ADL score rate between these two groups were compared. RESULTS: The six-month efficacy rates were 75% and 50% in patients receiving transsylvian-transinsular and transcortical-transtemporal surgery, respectively (p<0.05. Compared to the transcortical-transtemporal group, the proportion of revision surgery was statistically significantly lower in the transsylvian-transinsular group, (p<0.05. The proportion of post-surgery tracheostomy, the incidence of digestive tract hemorrhage, and the average length of hospital stay were lower in the transsylvian-transinsular group, compared to the transcortical-transtemporal group, but no statistically significant differences were noted in them between the two groups. CONCLUSION: The transsylvian-transinsular approach for evacuation of intracerebral hematoma demonstrates limited complications, shorter length of hospital stay, and improved long-term efficacy and prognosis. These findings suggest this operative approach has potential for wider application.

    OBJECTIVE: Recurrence rates of between 5% and 25% have been reported following surgery for chronic subdural hematoma (CSH). A previous study showed that the treatment with angiotensin converting enzyme (ACE) inhibitors decreases the risk of recurrence. To test the effects of ACE inhibitors on the recurrence CSH and CSH remnant six weeks after surgery, we conducted a prospective double-blinded randomized controlled clinical trial on patients with CSHs from July 2009 until October 2012. PATIENTS AND METHODS: Patients eligible for burr hole surgery for CSH were randomized into either an ACE inhibitor perindopril 5mg or placebo treatment daily for three months prior to surgery. Cerebral CT scans were performed after six weeks, and clinical follow-ups were performed three months after surgery. Additionally, a retrospective analysis of the data and CT scans from all nonrandomized patients from the same time period was performed. RESULTS: Forty-seven patients were included in the randomized study. The patients' preoperative Glasgow Coma Scale scores were 15. None of the patients in the randomized group developed a recurrence after surgery. Measurements of the sizes of the CSH before and six weeks after surgery revealed no difference between the placebo and perindopril-treated groups. In the retrospective group (245 patients), there was no correlation between the risk of recurrence and ACE inhibitor treatment. CONCLUSION: Our data suggest that perindopril does not diminish the size of residual CSHs six weeks after burr hole surgery and that ACE inhibitors do not decrease the risk of CSH recurrence.

  11. Plasma aldosterone and CT findings in head injury, especially in acute subdural hematoma

    International Nuclear Information System (INIS)

    As we have already reported, an increase in the plasma aldosterone level was regulary found after severe head injury. And the values of plasma aldosterone in unconscious patients with increased intracranial pressure were significantly higher than those in patients without unconsciousness. Thus, plasma aldosterone in acute phase of head injury seems to be a sensitive index of increased intracranial pressure. In the present study, we measured plasma aldosterone levels in three groups ; subdural hematoma with mid-line shift (group A), cerebral contusion without mid-line shift (group B) and cerebral conceussion (group C). In group A, the peak value of aldosterone was markedly high (283.9 ± 142.5). In B, the peak value (143.7 ± 27.8) was higher than in C (116.3 ± 35.0). And, correlation between the serum aldosterone levels and CT findings, especially the mid-line shift was found. As a conclusion, the serum levels of aldosterone seems to be associated with intracranial pressure. (author)

    BACKGROUND: An experimental swine model (n = 7) simulating an acute subdural hematoma (ASDH) was employed (1) to explore the relation between the brain tissue oxygenation (PbtO(2)) and the regional cerebral energy metabolism as obtained by microdialysis, and (2) to define the lowest level of PbtO(2) compatible with intact energy metabolism. METHODS: ASDH was produced by infusion of 7 ml of autologous blood (infusion rate 0.5 ml/min) by a catheter placed subdurally. PbtO(2) and microdialysis probes were placed symmetrically in the injured ("bad-side") and non-injured ("good-side") hemispheres. Intracranial pressure (ICP) was monitored in the "good-side." RESULTS: ICP, cerebral perfusion pressure (CPP), PbtO(2), glucose, lactate, pyruvate, lactate-pyruvate ratio (LP ratio), glutamate, and glycerol were recorded at baseline (60 min) and post trauma (360 min). After the creation of the ASDH, PbtO(2) decreased significantly in both the hemispheres (P

    Recombinant activated coagulation factor VII (rFVIIa) is known to be effective in the management of acquired deficiencies of factor VII and platelet function defects. But recently, rFVIIa has been successfully used to treat ongoing bleeding in disseminated intravascular coagulopathy (DIC) condition. The patient reported here was suspected to be suffering from toxic hepatitis on admission. After percutaneous liver biopsy, bleeding occurred and did not stop even after right hepatic artery embolization. The patient developed a severe hemorrhage that resulted in hypovolemic shock, hemoperitoneum, and a massive subcapsular hematoma. The patient then developed DIC due to massive transfusion, as well as acute liver necrosis. The patient was given 400 ?g/kg of rFVIIa. Recombinant factor VIIa was administered in an attempt to control the bleeding. This stabilized the hemoglobin levels of the patient. The patient gradually recovered in 4 months. In conclusion, this case suggests that rFVIIa can be successfully used for the hemostasis of uncontrolled bleeding in DIC. PMID:20651958

  15. Evaluating responsibility for schedule delays on utility construction projects

    International Nuclear Information System (INIS)

    The equitable allocation of responsibility for project delays is essential to the resolution of many construction disputes. Contractors frequently assert that they have been delayed for reasons beyond their control, but owners often remain unconvinced that the contractor is legitimately entitled to a time extension. Large dollar amounts may hinge upon the outcome of a dispute over project delay, since most construction contracts allow the owner to recover either liquidated or actual damages for delay and the contractor may be entitled to extended field and home office overhead costs because of owner-caused delays. Consequently, a thorough schedule analysis of the project delays is essential for the equitable resolution of delay-related disputes. Once all activity delays have been quantified, the origins and causes of each delay are then researched. Document sources used in this paper which identify the causes of project delays include: submittal, request for information, bulletins, change proposals, change orders, superintendents; diaries, contractor's and subcontrator's daily reports, project correspondence and meeting minutes. Responsibility for each delay is then apportioned to either the contractor or the owner

  16. Involvement of hypoxia-inducible factor-1? and vascular endothelial growth factor in the mechanism of development of chronic subdural hematoma

    International Nuclear Information System (INIS)

    Vascular endothelial growth factor (VEGF), a potent inducer of angiogenesis and vascular permeability in diverse physiological and pathological conditions, may be involved in the pathophysiology of chronic subdural hematoma (CSDH). The present study investigated the source and mechanisms for the induction of VEGF in CSDH by measuring the concentration of VEGF in the hematoma of 102 patients (122 hematomas) using the enzyme-linked immunosorbent assay technique. The relationship between the VEGF concentration in hematoma and the intrahematoma membranous structure confirmed by preoperative T2*-weighted magnetic resonance image was examined in 46 of these patients. VEGF and hypoxia-inducible factor-1? (HIF-1?) expression was immunohistochemically studied and microvessel density (MVD) in the outer membrane was identified using anti-CD31 antibody in 30 patients. VEGF and HIF-1? were positive in the outer membranes of all 30 patients. VEGF expression was significantly correlated to HIF-1? expression (rs= 0.651, p=0.0084) and VEGF concentration in the hematoma (rs=0.654, p=0.0013). VEGF concentration in layered hematomas, which have intrahematoma membranous structure, was significantly higher than in non-layered hematomas (p<0.01). Although MVDs of the outer membranes were comparable to those described in tumors, there was no significant relationship with VEGF expression. The present study suggests that VEGF in CSDH, which may be induced it VEGF in CSDH, which may be induced in the neomembrane by HIF-1 release, may give rise to the excessive development of fragile microvessels and hyperpermeability, resulting in the enlargement of CSDH.

  17. Nonlinear delay monopoly with bounded rationality

    International Nuclear Information System (INIS)

    The purpose of this paper is to study the dynamics of a monopolistic firm in a continuous-time framework. The firm is assumed to be boundedly rational and to experience time delays in obtaining and implementing information on output. The dynamic adjustment process is based on the gradient of the expected profit. The paper is divided into three parts: we examine delay effects on dynamics caused by one-time delay and two-time delays in the first two parts. Global dynamics and analytical results on local dynamics are numerically confirmed in the third part. Four main results are demonstrated. First, the stability switch from stability to instability occurs only once in the case of a single delay. Second, the alternation of stability and instability can continue if two time delays are involved. Third, the occurence of Hopf bifurcation is analytically shown if stability is lost. Finally, in a bifurcation process, there are a period-doubling cascade to chaos and a period-halving cascade to the equilibrium point in the case of two time delays if the difference between the two delays is large.

    Full Text Available Problem statement: The analysis and control of delayed systems are becoming more and more research topics in progress. This is mainly due to the fact that the delay is frequently encountered in technological systems. This can affect their significantly operations. Most control command laws are based on current digital computers and delays are intrinsic to the process or in the control loop caused by the transmission time control sequences, or computing time. The delay may affect one or more states of the considered system. It may also affect the establishment of the command. Several studies have investigated the stability of delay systems under the assumption that the delay is a variable phenomenon; such variation is considered to be bounded or limited to facilitate analysis of the system. In this study we propose a modelling of delayed system by using the multimodels and switched system theory. The analysis of stability is based on the use of second Lyapunov method. The issued stability conditions are expressed as Bilinear Matrix Inequalities impossible to resolve. That?s why we propose the same original relaxations to come over this difficulty, an example of induction machine is given to illustrate over approach. Approach: We propose to use the control theory developed for switched systems to synthesis a control laws for the stabilisation of delays system. Results: We stabilize the induction machine around many operating points despite the non linearities. Conclusion: The developed method is less conservative and less pessimistic than the used classical methods.

  19. Delay discounting: Trait variable?

    Delay discounting refers to the tendency for outcomes that are remote in time to have less value than more immediate outcomes. Steep discounting of delayed outcomes is associated with a variety of social maladies. The degree of sensitivity to delayed outcomes may be a stable and pervasive individual characteristic. In analyses of archival data, the present study found positive correlations between the degree of delay discounting for one outcome (as measured by the Area Under the Curve), and the degree of discounting for other outcomes. Along with additional evidence reviewed, these data suggest that delay discounting may be considered a personality trait. Recent research in epigenetics, neuroscience, and behavior suggests delay discounting may prove to be a beneficial target for therapeutic attempts to produce global reductions in impulsivity related to delay discounting.

    Full Text Available Abstract Background Genomic imbalances of the 12q telomere are rare; only a few patients having 12q24.31-q24.33 deletions were reported. Interestingly none of these were mosaic. Although some attempts have been made to establish phenotype/genotype interaction for the deletions in this region, no clear relationship has been established to date. Results We have clinically screened more than 100 patients with dysmorphic features, mental retardation and normal karyotype using high density oligo array-CGH (aCGH and identified a ~9.2 Mb hemizygous interstitial deletion at the 12q telomere (Chromosome 12: 46,XY,del(12(q24.31q24.33 in a severely developmentally retarded patient having dysmorphic features such as low set ears, microcephaly, undescended testicles, bent elbow, kyphoscoliosis, and micropenis. Parents were found to be not carriers. MLPA experiments confirmed the aCGH result. Interphase FISH revealed mosaicism in cultured peripheral blood lymphocytes. Conclusions Since conventional G-Banding technique missed the abnormality; this work re-confirms that any child with unexplained developmental delay and systemic involvement should be studied by aCGH techniques. The FISH technique, however, would still be useful to further delineate the research work and identify such rare mosaicism. Among the 52 deleted genes, P2RX2, ULK1, FZD10, RAN, NCOR2 STX2, TESC, FBXW8, and TBX3 are noteworthy since they may have a role in observed phenotype.

    A 2-month-old female infant, born to consanguineous parents, presented with infections in skin and upper respiratory tract. She was notable for delayed umbilical cord detachment, partial albinism, and neurological irritability. Giant granules were present in white blood cells. The intracellular perforin content in CD8 T cells seems to correlate to the immune activation state of the patient with 82% and 8% perforin-containing CD8 T cells at active and nonactive hemophagocytic lymphohistiocytosis (HLH) disease, respectively. HLH was confirmed by hemophagocytosis in bone marrow and absent natural killer cell activity. The patient carried a homozygous G>A mutation in the 3' splice site of intron 24 of the LYST/CHS1 gene, leading to the use of an alternative YAG splice site located in exon 25, introducing a premature STOP codon (L2355fsX2370; NP_000072.2). The early-onset accelerated phase in this severe phenotype of Chediak-Higashi syndrome was probably induced by rotaviral infection. Interestingly, the intracellular perforin content in CD8 T cells seems to correlate to the immune activation state of the patient. Late separation of the umbilical cord in concordance with clinical symptoms should lead to evaluation of a possible neutrophil dysfunction including Chediak-Higashi syndrome before onset of HLH.

Two peaks of higher incidence were observed: 30-39 years (31% and 60-69 years (29%. The length of time from the beginning of symptoms until diagnosis ranged from 4 hours to 29 weeks. Headache was the main complaint in 26/35 (74.3% patients; changes in the level of consciousness in 14/35 (40.0%; vomiting in 11/35 (31,4%; hemiplegia or hemiparesis in 8/35 (22.9%; diplopia or VI nerve paresis in 5/35 (14.3%; and language disorders in 4/35 (11.4%. Contributing factors included: pregnancy, multiple punctures, use of anticoagulants, intracranial vascular abnormalities, and brain atrophy. In 15 cases, a contributing factor was not mentioned. Four out of 35 patients (11.4% remained with neurologic sequelae, and 4/35 (11.4% died. CONCLUSIONS: The presence of any of the signs or symptoms mentioned above should alert for the possibility of an intracranial subdural hematoma as a complication of puncture of the dura mater, especially in those patients with PDPH for more than one week, at which time investigation by neuroimaging is necessary.

    We propose an optical delay line based on differential structure for improving measurement accuracy and extending scanning length of optical coherence domain polarimetry (OCDP). The differential delay line is composed of two independent graded refractive index lenses (GRIN) and a double-faced mirror. The OCDP measurement model with loss coefficient and measurement error caused by the GRIN-lens-based delay line is discussed. Compared to the general optical delay line based on a single GRIN lens, the fluctuation of the loss coef?cient of differential delay line is reduced to ± 0.1?dB with scanning range of 0.8?m, which corresponds to 80% improvement.

Shortly after, the patient had a typical cholinergic crisis that was treated with 2 mg of endovenous atropine every 5 min, ventilatory support and [...] general measures. Serum cholinesterase was deeply inhibited since the patient was admitted. In spite of the apparent favorable clinical evolution, the patient could not be disconnected from ventilation., and that's why the diagnosis of intermediate syndrome due to phosphate poisoning was made. The non use of cholinesterase regenerators together with the delay to seek medical assistance could influence on the production of the syndrome. It was concluded that the intemediate syndrome due to phosphate poisoning is a serious and rare condition that complicates the evolution of these patients.
