Delayed post-operative contralateral epidural hematoma in a patient with right-sided acute subdural hematoma: a case report  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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.

Delayed spinal extradural hematoma following thoracic spine surgery and resulting in paraplegia: a case report  

Directory of Open Access Journals (Sweden)

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.

Delayed traumatic hematomas of the brain: the early manifestations of CT  

International Nuclear Information System (INIS)

Objective: To study the CT manifestations of delayed traumatic hematomas of the brain and evaluate their diagnostic significance in predicting the delayed traumatic brain hematoma. Methods: The manifestations of initial CT studies and follow-up CT examinations of 31 delayed traumatic brain hematomas were analyzed. Another 50 CT studies of head trauma without delayed brain hematomas were included randomly as control. Results: The abnormal findings of CT studies of the 31 delayed traumatic brain hematomas included: (1) Decreased density of the local brain parenchyma and disappeared difference between gray and white matter of the same area in 18 cases; (2) Local subarachnoid space hemorrhage in 24 cases; (3) Slight mass effect of local brain parenchyma in 16 cases. (4) Subdural hematoma in 9 cases. The locations of the abnormalities were roughly the same with the delayed hematoma except one local subarachnoid space hemorrhage, which was in the opposite of the delayed hematoma. The appearing rate of those abnormal findings in the control group was low and the difference was statistically significant. Conclusion: The decrease of density of local brain parenchyma, the disappeared difference between the gray and white matter, local subarachnoid space hemorrhage, and local swollen of brain presented in the initial CT study of the patient with heat trauma should be taken as indicators of delayed hemorrhage of the same area of brain, and it is necessary to do follow-up CT studid it is necessary to do follow-up CT studies to exclude it

[Case of renal subcapsular hematoma caused by flexible transurethral lithotripsy].  

Science.gov (United States)

A 39-year-old man with macroscopic hematuria was admitted to our hospital. A stone, 5 mm in diameter was detected in the right ureteropelvic junction after abdominal computed tomography and plain abdominal radiography. We performed flexible transurethral lithotripsy (f-TUL) and crushed the stone and extracted almost all stone fragments without any complications. However, almost immediately after the operation, the patient began to complain about pain in the right back. In the results of abdominal plain computed tomography right renal subcapsular hematoma was detected. Because active bleeding was not observed in the results of enhanced computed tomography, only conservative treatment was performed. The patient was discharged from the hospital on day 11 of hospitalization. One month after the operation, plain computed tomography was performed and diminished subcapsular hematoma was detected. Renal subcapsular hematoma is assumed to be a unique complication of extracorporeal shock wave lithotripsy. This is the first report of a case of renal subcapsular hematoma caused by f-TUL. The onset of renal subcapsular hematoma following f-TUL could have been caused either because the laser fiber thrust into the renal lithiasis unintentionally or because the internal pressure of the renal pelvis increased substantially during the operation.

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.

Subdural hematoma caused by epithelioid angiosarcoma originating from the skull.  

Science.gov (United States)

Cancers metastatic to the skull or dura may cause subdural hematoma (SDH). However, the frequency is low, and the presence of underlying cancers has almost always been known in such situations. We report a case of skull angiosarcoma manifesting as SDH, posing a diagnostic challenge to physicians. A 75-year-old man visited our clinic with sensorimotor disturbance of gradual onset approximately 1 month after a minor head trauma. He was diagnosed with SDH after imaging studies, and underwent surgery to evacuate the hematoma. Because the hematoma was organized, surgery was switched from burr-hole drainage to craniotomy. The bone flap as well as the dura over the hematoma had grossly normal appearance, and only the hematoma itself was submitted for histological examination. Although postoperative recovery was uneventful, the patient experienced recurrence of the SDH 2 months after surgery. At the second surgery, the bone flap and dura were intermingled with tumor tissue, and histological examination revealed that an epithelioid angiosarcoma originating from the skull was responsible for the SDH. Timely diagnosis of angiosarcoma manifesting as SDH is difficult because of its rarity. In retrospect, however, the diagnosis might have been established earlier if the bone flap and/or the dura had been biopsied at the time of the first surgery. The present case gives us a lesson that SDH may be an unusual manifestation of malignant tumors of skull or dural origin, and histological examination of not only hematoma capsule but also of the surrounding tissues may provide important diagnostic clues.

Preventing graft loss caused by hematoma: experimental study.  

Science.gov (United States)

Hematoma is a common reason for graft loss. This study was intended to investigate the effects of microporous polysaccharide hemospheres (MPH; Arista® AH; Medafor, Inc.) on graft survival, the effect of MPH on graft loss caused by hematoma, and the correlation between neutrophil accumulation and graft survival. A total of 35 adult male Wistar rats were separated into five groups of seven as follows: control 1, saline, MPH, control 2 (hematoma group), and MPH + hematoma. All graft dressing was removed on the fifth postoperative day and graft survival percentage measured. Histopathological and semiquantitative analysis, including inflammatory cell infiltration and subcutaneous inflammation based on neutrophil count, was performed. Graft survival significantly improved in the MPH group (97.86 ± 1.676) compared with the control 1 (91.14 ± 3.671; P = .004) and saline groups (91.57 ± 4.791; P = .014). There was no significant increase in graft survival in the saline group compared with the control 1 group or in the MPH + hematoma group (19.57 ± 14.707) compared with the control 2 group (20.71 ± 16.869; P > .05). The neutrophil count was highest in the control 2 group (177.43 ± 22.464) and significantly decreased in the MPH group (33. 71 ± 8,674) compared with the control 1 group (66.14 ± 5.872; P = .001) and the saline group (65.57 ± 3.309; P= .001). There was no significant decrease in neutrophil count in the MPH + hematoma group (160.00 ± 27.952) compared with the control 2 group (P > .05). It seems that MPH can increase the graft survival, and there is an inverse relationship between graft survival and neutrophil accumulation. PMID:24823329

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)

Postoperative epidural hematoma contributes to delayed upper cord tethering after decompression of Chiari malformation type I  

Science.gov (United States)

Background: Symptomatic arachnoiditis after posterior fossa surgical procedures such as decompression of Chiari malformation is a possible complication. Clinical presentation is generally insidious and delayed by months or years. It causes disturbances in the normal flow of cerebrospinal fluid and enlargement of a syrinx cavity in the upper spinal cord. Surgical de-tethering has favorable results with progressive collapse of the syrinx and relief of the associated symptoms. Case Description: A 30-year-old male with Chiari malformation type I was treated by performing posterior fossa bone decompression, dura opening and closure with a suturable bovine pericardium dural graft. Postoperative period was uneventful until the fifth day in which the patient suffered intense headache and progressive loose of consciousness caused by an acute posterior fossa epidural hematoma. It was quickly removed with complete clinical recovering. One year later, the patient experienced progressive worsened of his symptoms. Upper spinal cord tethering was diagnosed and a new surgery for debridement was required. Conclusions: The epidural hematoma compressing the dural graft against the neural structures contributes to the upper spinal cord tethering and represents a nondescribed cause of postoperative fibrosis, adhesion formation, and subsequent recurrent hindbrain compression.

Recovery after delayed surgery in a case of spinal subdural hematoma.  

Science.gov (United States)

Spinal chronic subdural hematoma (SCSH) is a rare pathology usually associated with trauma or hematological alterations or is due to iatrogenic causes; rarely SCSH can be spontaneous. We report a case of a 79-year-old female who underwent a surgical evacuation of a spontaneous SCSH one year after diagnosis. She presented with a severe paraparesis and showed a considerable improvement in sensory-motor performances after surgery. The treatment of spontaneous SCSH is not well defined and universally accepted. Early surgery is mandatory in cases presenting with severe deficits. To the best of our knowledge, this is the first case showing a good outcome in a case of SCSH following a delayed surgery. In our opinion, an aggressive approach should be considered as a viable option in cases of spontaneous SCSH even after a lasting spinal cord compression. PMID:23365771

Expanding hematoma of the abdominal walI caused by spontaneous rupture of a deep circumflex iliac artery: report of a case treated by coil embolization  

Energy Technology Data Exchange (ETDEWEB)

Abdominal wall hematoma is a rare but well-known disease, usually caused by trauma or, on rare occasions, occurring spontaneously. Hematomas of the rectus sheath and the anterolateral abdominal wall are commonly associated with injury to the inferior epigastric artery and the deep circumflex iliac artery, respectively. The diagnosis of spontaneously developed abdominal wall hematoma is sometimes delayed, due its clinical manifestations being similar to those of other causes of the acute abdomen. CT and angiography can be helpful in the diagnosis of the hematoma and the injured vessel. Herein, we report on a rare case of a spontaneously developed anterolateral abdominal wall hematoma treated with microcoil embolization of the left deep circumflex iliac artery.

Axillary artery injury combined with delayed brachial plexus palsy due to compressive hematoma in a young patient: a case report  

Directory of Open Access Journals (Sweden)

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.

Delayed duodenal obstruction after intramural hematoma in a patient with paroxysmal nocturnal hemoglobinuria: A case report  

Science.gov (United States)

INTRODUCTION Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal stem cell disorder of hematopoietic cells. Gastrointestinal complications of PNH are rare and mostly related with intravascular thrombosis or intramural hematoma. PRESENTATION OF CASE We describe a case of a man with PNH complicated by intramural duodenal hematoma initially treated with supportive care. Three months after his first admission; he was admitted to the emergency department with abdominal pain, nausea and vomiting. He had undergone to surgery because of duodenal obstruction was treated with duodenojejunal by-pass surgery. DISCUSSION Patients were healed from gastrointestinal complications could suffer from gastrointestinal strictures, which cause wide spread symptoms ranging from chronic abdominal pain and anorexia to intestinal obstruction. CONCLUSION We report a rare intestinal obstruction case caused by stricture at the level of ligamentum Treitz with PNH. The possibility simply has to be borne in mind that strictures can be occurring at hematoma, ischemia or inflammation site of gastrointestinal tract. PMID:25123648

A rare cause of duodenal obstruction: Intramural hematoma  

Directory of Open Access Journals (Sweden)

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

Intramuscular Hematomas Caused by Anticoagulant Therapy: Is Advanced  

Directory of Open Access Journals (Sweden)

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.

Delayed Diagnosis of Pelvic Hematoma without Fracture Due to Military Parachuting.  

Science.gov (United States)

The U.S. military has been conducting static-line parachute jumps for nearly a century. Beginning with World War II, military forces have also employed full-scale airborne operations as a method for insertion into combat. Through the years, injuries from blunt trauma as a result of static-line parachute jumps have evolved little with the refinement of equipment, training, and tactics. Parachute jumps continue to invoke primarily musculoskeletal injuries, especially to the lower extremities, back, neck, and head. These injuries are usually straightforward in their presentation and diagnosis. We describe the delayed diagnosis of a pelvic hematoma due to an uncommon blunt trauma jump injury. The purpose of this case report is to increase awareness of injury patterns during paratrooper operations, as well as to review the diagnosis and management of occult hemorrhage. Specific objectives for the readers are to (1) know the common injury types and patterns for airborne operations, (2) know the descent rate of T-10C/D parachutes and factors influencing the rate, (3) recognize signs and symptoms associated with a pelvic hematoma, and (4) recognize common complications resulting from a pelvic hematoma.

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)

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

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)

Rectus sheath hematoma caused by non-contact strenuous exercise mimicking acute appendicitis.  

Science.gov (United States)

A healthy 26-year-old man visited the Emergency Department due to right lower quadrant pain of 2 days' duration that developed after wakeboarding. There was no history of direct trauma to the abdomen. Physical examination revealed tenderness and rebound tenderness on the right lower quadrant area. There was no palpable abdominal mass. Computed tomography (CT) of the abdomen was undertaken to discern the causes of acute abdomen, including acute appendicitis. CT revealed a small-size rectus sheath hematoma beneath the lower end of the right rectus muscle. The patient was admitted for supportive care including pain control and was discharged with improvement after 5 days. Rectus sheath hematoma can be caused by not only a direct blow but also non-contact strenuous exercise, for example, wakeboarding in this case. Although the majority of rectus sheath hematomas are self-limiting, some can cause peritoneal irritation signs, mimicking acute abdomen, and eventually lead to unnecessary laparotomy without clinical suspicion and ancillary tests including CT scan and ultrasonography.

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

Two cases of subdural hematoma with niveau formation on CT. A study of the cause of niveau formation  

Energy Technology Data Exchange (ETDEWEB)

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

Hematoma and abscess formation caused by Mycoplasma hominis following cesarean section  

Directory of Open Access Journals (Sweden)

Full Text Available Hisato Koshiba1,2, Akemi Koshiba1,2, Yasushi Daimon3, Toshifumi Noguchi1,2, Kazuhiro Iwasaku2, Jo Kitawaki21Department of Obstetrics and Gynecology, Kyoto Prefectural Yosanoumi Hospital, Kyoto, Japan; 2Department of Obstetrics and Gynecology, Kyoto Prefectural University of Medicine, Graduate School of Medical Science, Kyoto, Japan; 3Department of Clinical Laboratory, Kyoto Prefectural Yosanoumi Hospital, Kyoto, JapanAbstract: Mycoplasma species cannot be identified by routine bacteriological culture methods and are resistant to common antimicrobial agents. Mycoplasma hominis usually colonizes the lower urogenital tract and causes pyelonephritis, pelvic inflammatory disease, chorioamnionitis, rupture of fetal membranes, preterm labor, postpartum fever, postabortal fever, and neonatal infection. This organism is highly prevalent in cervicovaginal cultures of sexually active women. M. hominis, M. genitalis, Ureaplasma urealyticum, and U. parvum may invade and infect placental and fetal tissues, leading to adverse pregnancy outcomes. M. hominis occasionally causes nongenitourinary infection of the blood, wounds, central nervous system, joints, or respiratory tract. We present a case of a 27-year-old woman who developed abdominal wound hematoma and abscess after cesarean section. The wound was drained, but her high fever persisted, in spite of antibiotic treatment using flomoxef sodium and imipenem•cilastatin sodium. Because the exudate exhibited M. hominis growth in an anaerobic environment, we administered the quinolone ciprofloxacin. This therapy resolved her fever, and her white blood cell count and C-reactive protein level diminished to the normal ranges. To our knowledge, there are four published articles regarding the isolation of M. hominis from postcesarean incisions. Based on the current study and the literature, infection by this pathogen may cause hematoma formation with or without abscess after cesarean section or in immunosuppressed postoperative patients. In such cases, physicians may need to suspect Mycoplasma infection and initiate appropriate antibacterial treatment as soon as possible in order to avoid persistent fever.Keywords: Mycoplasma hominis, cesarean section, hematoma, abscess

Subarachnoid hemorrhage and intracerebral hematoma caused by aneurysms of the anterior circulation: influence of hematoma localization on outcome.  

Science.gov (United States)

Additional space-occupying intracerebral hematoma (ICH) in patients suffering from subarachnoid hemorrhage (SAH) is a known predictor for poor outcome. Emergent clot evacuation might be mandatory. However, data concerning the influence of ICH location on outcome is scarce. Therefore, we analyzed the influence of ICH location on clinical course and outcome in patients with SAH and additional ICH. One hundred seventy-four patients were treated with aneurysmal SAH and additional ICH between September 1999 and May 2012. Information including patient characteristics, treatment, and radiological findings were prospectively entered into a database. Patients were stratified according to ICH location and neurological outcome. Neurological outcome was assessed according to modified Rankin Scale (mRS). ICH location was temporal (58.6 %), frontal (28.7 %), and perisylvian ICH (12.6 %); 63.8 % presented in poor admission status and favorable outcome was achieved in 35.6 %. In the multivariate analysis, favorable outcome was associated with young age, ICH <50 ml, and good admission status. The location of ICH was not associated with outcome. The current data confirms that a significant number of patients with ICH after aneurysm rupture achieve favorable outcome. Prognostic factor for favorable outcome are "age," "size of the hematoma," and "admission status." The location of the ICH seems not to be associated with outcome. PMID:25011406

Abdominal chronic expanding hematoma causing iron-deficiency anemia in a dog.  

Science.gov (United States)

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

Spontaneous Rectus Sheath Hematoma  

Directory of Open Access Journals (Sweden)

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

Hemophilia and child abuse as possible causes of epidural hematoma: case report  

Directory of Open Access Journals (Sweden)

Full Text Available INTRODUCTION: Head trauma is an important consequence of child abuse. Specific pathophysiological mechanisms in child abuse are responsible for the ''whiplash shaken-baby syndrome'', which would favour the occurrence of intracranial hemorrhages. CASE REPORT: We report the case of a child who developed epidural hematoma following minor-intensity head trauma. Initial diagnosis of child abuse was made, but subsequent investigation led to the diagnosis of hemophilia A. CONCLUSION: Even though epidural hematoma is not closely associated with child abuse, this aethiology must always be considered when the reported trauma mechanism is out of proportion to the magnitude of the encountered lesions.

Complete motor recovery after acute paraparesis caused by spontaneous spinal epidural hematoma: case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Spontaneous spinal epidural hematoma is a relatively rare but potentially disabling disease. Prompt timely surgical management may promote recovery even in severe cases. Case presentation We report a 34-year-old man with a 2-hour history of sudden severe back pain, followed by weakness and numbness over the bilateral lower limbs, progressing to intense paraparesis and anesthesia. A spinal magnetic resonance imaging scan was performed and revealed an anterior epidural hematoma of the thoracic spine. He underwent an emergency decompression laminectomy of the thoracic spine and hematoma evacuation. Just after surgery, his lower extremity movements improved. After 1 week, there was no residual weakness and ambulation without assistance was resumed, with residual paresthesia on the plantar face of both feet. After 5 months, no residual symptoms persisted. Conclusions The diagnosis of spontaneous spinal epidural hematoma must be kept in mind in cases of sudden back pain with symptoms of spinal cord compression. Early recognition, accurate diagnosis and prompt surgical treatment may result in significant improvement even in severe cases.

Hematoma suprarrenal Suprarrenal hematoma  

Directory of Open Access Journals (Sweden)

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

Causes of delay in road construction projects in Malawi  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english 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.

Imperative Causes of Delays in Construction Projects from Developers’ Outlook  

Directory of Open Access Journals (Sweden)

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

The Surgical Treatment of Three Young Chronic Subdural Hematoma Patients with Different Causes  

Science.gov (United States)

Chronic subdural hematoma (CSDH), which rarely happens in the young, is thought to be a disease of the elderly. Whereas unspecific symptoms and insidious onset in juveniles and young adults, as a result of its relative low morbidity, CSDH is usually neglected even undertreated in the young. Through the three cases and review of the current literature on this subject, we tried to illustrate the clinical and etiopathological characteristics of this entity and find out the most appropriate treatment strategy. We report three young CSDH patients with different but similar symptoms. The present histories, tests and examinations revealed different predisposing factors accounting for the genesis of CSDH. Their preoperative symptoms were all resolved with burr hole and drainage operation. Juveniles and young adults suffering from CSDH differ from that of their elderly counterparts in their clinical and etiopathological characteristics. Although trauma is the most important risk factor in young and old CSDH patients, some other predisposing factors may exist. Burr hole and drainage surgery could resolve the problem most of the time. But further tests and examinations even specific management should be made in some cases. PMID:25024828

Occlusive intraluminal hematoma  

Energy Technology Data Exchange (ETDEWEB)

We report an unusual case of a 10-month-old girl who developed partial small-bowel obstruction caused by an intraluminal hematoma within the terminal ileum. Passage of bright red blood through her rectum prompted radiologic evaluation with computed tomography, barium enema, and ultrasound. These revealed an avascular right lower-quadrant mass within the lumen of the terminal ileum. An exploratory laparotomy was performed, and a large obstructing hematoma was removed. (orig.)

The authors recommend surgical revision, in particular in children because the mechanism of injury is the same in intramural haematoma and in duodenal perforation. Only thus it is possible to prevena a fatal course, while the operation is easy and healing after drainage of the haematoma is rapid. PMID:2749389

Spontaneous intracerebral hematomas  

International Nuclear Information System (INIS)

Thirty-six cases of so-called spontaneous intracerebral hematoma were analyzed with special reference to clinical signs and symptoms, computerized tomography (CT) scan findings and postoperative courses. Hematomas due to cerebral aneurysms, arterio-venous malformations, blood dyscrasias as well as traumatic and hypertensive intracerebral hematomas were excluded from this series. The patients varied in age from 7 months to 74 years with the mean age of 40 years. Caution must be paid to the fact that the age group of more than 50 years occupied 37% of the whole cases. The lesions were located predominantly in the parietal lobe (52%) and 36% were in the frontal or temporal lobe which had been said the most prevalent site of the lesion. There were 4 hematomas which located in the occipital lobe and all of them were the cases in CT era. CT scan was very useful for the diagnosis of small hematomas, particularly in such regions as parietal or occipital lobe, where arteriography offered insufficient evidence to substantiate the diagnosis of intracerebral hematoma in pre-CT era. However, arteriography should not be neglected in order to detect aneurysms or arteriovenous malformations which could not be visualized by CT scan. Small angiomatous malformations as a cause of hematoma were found in only 7 cases by either arteriography or pathologic examination. In all except 2 patients, craniotomy was carried out and 52% of them returned to their prevenous occupations. In contrast, their prevenous occupations. In contrast, only 4 of 14 patients of more than 50 years could get full social recovery and the postoperative improvement depended on the age of the patient. (author)

Optical signal path delay fluctuations caused by atmospheric turbulence.  

Science.gov (United States)

We report the first direct measurements, to our knowledge, of optical signal path delay fluctuations caused by optical turbulence in the atmosphere. The experiments were based on satellite laser ranging. Our initial motivation was to identify all the random error contributors in satellite laser ranging. We measured and identified the random path fluctuations caused by the atmosphere in the range of units of picoseconds. An appropriate fluctuation model was developed. PMID:16092339

Transcatheter Embolization for Delayed Hemorrhage Caused by Blunt Splenic Trauma  

International Nuclear Information System (INIS)

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

Mutations in KPTN Cause Macrocephaly, Neurodevelopmental Delay, and Seizures  

Science.gov (United States)

The proper development of neuronal circuits during neuromorphogenesis and neuronal-network formation is critically dependent on a coordinated and intricate series of molecular and cellular cues and responses. Although the cortical actin cytoskeleton is known to play a key role in neuromorphogenesis, relatively little is known about the specific molecules important for this process. Using linkage analysis and whole-exome sequencing on samples from families from the Amish community of Ohio, we have demonstrated that mutations in KPTN, encoding kaptin, cause a syndrome typified by macrocephaly, neurodevelopmental delay, and seizures. Our immunofluorescence analyses in primary neuronal cell cultures showed that endogenous and GFP-tagged kaptin associates with dynamic actin cytoskeletal structures and that this association is lost upon introduction of the identified mutations. Taken together, our studies have identified kaptin alterations responsible for macrocephaly and neurodevelopmental delay and define kaptin as a molecule crucial for normal human neuromorphogenesis.

[Spontaneous orbital hematoma: two case reports].  

Science.gov (United States)

Although rare, spontaneous intra-orbital hematoma can quickly jeopardize vision. It usually presents with painful proptosis. It can result from multiple etiologies, and the diagnosis is based on imaging studies in the absence of known causes. We describe two cases of spontaneous intraorbital hematoma. The first, of unknown etiology, required needle drainage. The second was associated with a subperiosteal hematoma of the orbital roof complicating a periorbital bone infarction in a patient with sickle-thalassemia. PMID:22795759

Pseudosepsis: rectus sheath hematoma mimicking septic shock.  

Science.gov (United States)

There are many noninfectious disorders in the critical care unit (CCU) that mimic sepsis. Pseudosepsis is the term applied to noninfectious disorders that mimic sepsis. Fever/leukocytosis is not diagnostic of infection but frequently accompanies a wide variety of noninfectious disorders. When fever/leukocytosis and hypotension are present, sepsis is the presumptive diagnosis until proven otherwise. After empiric therapy for sepsis is initiated, the clinician should rule out the noninfectious causes of pseudosepsis. The most common causes of pseudosepsis in the CCU setting are pulmonary embolism, myocardial infarction, gastrointestinal hemorrhage, overzealous diuretic therapy, acute pancreatitis, relative adrenal insufficiency, and (rarely) rectus sheath hematoma. Rectus sheath hematoma may occur secondary to trauma/anticoagulation therapy and may present as an acute surgical abdomen mimicking sepsis. Rectus sheath hematoma should be considered when other causes of pseudosepsis or sepsis fail to explain persistent hypotension unresponsive to fluids/pressors. The diagnosis of rectus sheath hematoma is by abdominal ultrasound or computed tomography scan. If the abdominal computed tomography scan is negative for other intra-abdominal pathology and other causes of pseudosepsis are eliminated, then the diagnosis of pseudosepsis caused by rectus sheath hematoma is confirmed by demonstrating a hematoma in the rectus sheath. Treatment of rectus sheath hematoma is surgical drainage and ligation of any bleeding vessels. Evacuation of the rectus sheath hematoma rapidly reverses the patient's hypotension and is curative. We describe a case of pseudosepsis caused by rectus sheath hematoma in an elderly man with hypotension unresponsive to fluids/pressors and mimicking septic shock. Clinicians should be aware that rectus sheath hematoma is a rare but important cause of pseudosepsis in patients in the CCU. PMID:17137947

Rectus Sheath Hematoma Mimicking Acute Abdominal Pain  

Directory of Open Access Journals (Sweden)

Full Text Available Abdominal sheat hematoma is a rare cause of acute abdominal disorders and may be misdiagnosed from other causes of abdominal pain. Early diagnosis is mandatory in order to avoid morbidity or unnecessary surgery. We describe a case of an 55-year-old men receiving anticoagulants who presented with typical clinical manifestations of acute surgical abdomen. A computed tomography scans demonstrated a right rectus sheath hematoma. The patient was treated conservatively with success. It is important to recognize this entity of rectus sheath hematoma among patients complaining of acute abdominal pain. [Cukurova Med J 2012; 37(4.000: 243-246

Traumatic Aortic Intramural Hematoma  

Directory of Open Access Journals (Sweden)

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.

Laparoscopic drainage of an intramural duodenal hematoma.  

Science.gov (United States)

A 21-year-old man was admitted with vomiting and abdominal pain 3 days after sustaining blunt abdominal trauma by being tackled in a game of American football. A diagnosis of intramural hematoma of the duodenum was made using computed tomography and upper gastrointestinal tract contrast radiography. The hematoma caused obstructive jaundice by compressing the common bile duct. The contents of the hematoma were laparoscopically drained. A small perforation was then found in the duodenal wall. The patient underwent laparotomy and repair of the injury. Laparoscopic surgery can be used as definitive therapy in this type of abdominal trauma. PMID:10204621

Magnetic resonance imaging of intracranial hematoma  

International Nuclear Information System (INIS)

A sequential MR scan was performed on 21 patients with intracranial hematoma, and simultaneously the T1 values of the hematomas were calculated. The T1 value of a hematoma was found to be longer than that of the white matter in the acute phase, but it soon becomes as short as that of the white matter (7 - 10 day after). After several days, the T1 value again gradually becomes longer. In the experiment, 30 ml of fresh blood (15 samples) were stored at room temperature, and a sequential MR scan and the calculation of the T1 were performed over a period of 20 days. In vitro, most of the T1 values were long, but there was much variation on the first day. A shortening of the T1 was observed as well in vivo, and after this shortening, no prolongation of the T1 was observed. Perhaps the shortening of T1 was caused by the denaturation of the hemoglobin to methemoglobin and by the coagulation of the blood. The lysis and absorption of the hematoma may, on the other hand, cause the prolongation of the T1 in vitro. For the diagnosis of intracranial hematoma, CT was found to be a method superior to MRI, especially in the acute phase. However, MRI gives us more information about hematoma (concerning the denaturation of the hemoglobin to methemoglobin, the lysis and absorption of the hematoma, the range of hemorrhagic tissue and edema, etc.) than does CT. An IR (T1-weighted)an does CT. An IR (T1-weighted) image shows a good contrast between the hematoma and the surrounding tissue (hemorrhagic tissue, edema) in the early phase. On the other hand, the SE (T2-weighted) image informs us of the lesion when the hematoma is low ? isodense on the CT in the chronic phase. (author)

Project Management Patterns to Prevent Schedule Delay Caused by Requirement Elicitation  

Science.gov (United States)

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

Hematoma volume as the major determinant of outcomes after intracerebral hemorrhage.  

Science.gov (United States)

Intracerebral hemorrhage (ICH) is a leading cause of morbidity and mortality, greatly linked to hematoma volume. Understanding the characteristics and size of hematoma is integral to evaluating severity and prognosis after ICH. Examination of the literature suggests that markers for hematoma size vary, but the key range between 20-30 mL is most widely used as the cut-off for classification of hematoma volume. The role of hematoma volume in episodes of hematoma expansion and re-bleeding further impact outcomes, with increased growth associated with larger hematoma volume. Additionally, many commonly used predictors of ICH outcomes are directly related to hematoma volume, implicating it as an important variable when determining outcomes. In conclusion, hematoma volume is likely the most significant determinant of outcomes in intracerebral hemorrhage. PMID:25034055

Surgical treatment of supra- and infratentorial epidural hematoma.  

Science.gov (United States)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

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

International Nuclear Information System (INIS)

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

Computed Tomography Angiography for Detection of Middle Meningeal Artery Lesions Associated with Acute Epidural Hematomas  

Science.gov (United States)

Background. The natural history of traumatic aneurysms of the middle meningeal artery (MMA) is not well known, but patients with these lesions are more likely to have delayed bleeds. In this paper, we described a series of patients with epidural hematoma who underwent angiotomography (CTA) for MMA vascular lesion diagnosis. Methods. Eleven patients admitted to our emergency unit with small acute epidural hematoma were prospectively studied. All patients with temporal acute epidural hematomas underwent CTA and cerebral angiogram at our institution for diagnosis of posttraumatic lesions of middle meningeal artery. The findings of angiotomography and digital angiography were reviewed by radiologist and angiographers, respectively, to ensure that the lesions were readily diagnosed without knowing the results of angiotomography and to compare CTA findings with standard angiogram. Results. The causes of head injury were traffic accidents, falls, and aggression. Three of these patients presented traumatic MMA pseudoaneurysm. CT angiography was able to diagnose all of them, with dimensions ranging from 1.5 to 2.8?mm. Conventional angiography confirmed the findings of CT angiography, and the lesions presented with similar dimensions at both methods. Conclusions. We believe that angiotomography can be a useful technique for diagnosis of vascular lesion associated with small epidural hematoma. PMID:24800222

Caso 2: Paciente femenino de 40 años, con un hematoma vermiano asintomático de 1 cm encontrado en la TAC de control a las 72 horas de la cirugía. Evolución sin déficit neurológico. Conclusión. La cirugía supratentorial con pérdida abundante de LCR sería el factor más importante de esta complicación. El hiperdrenaje de LCR produce relajación del cerebelo con la consiguiente tracción y rotura de las venas puente que van a la tienda, provocando hematomas subdurales e infartos venosos hemorrágicos del cerebelo.

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

Traumatic acute intracerebellar hematoma  

International Nuclear Information System (INIS)

Recently, detection of posterior fossa hematomas has been greatly expedited by the advent of computed tomography, however traumatic acute intracerebellar hematomas have remained rare; there have been only 12 cases reported in the literature. Herein we reported a case in which the patient survived after diagnosis and surgical intervention. Documenting our case with analysis of 13 reported cases, including ours, following comments were appeared obvious; the characteristic features of traumatic acute intracerebellar hematoma were occipital contused wound, occipital fracture, headache and vomiting. The patient became progressively or rapidly comatous with respiratory distress. Focal signs of the posterior fossa were not characteristic. The computed tomography was useful in diagnosis and follow-up study. Especially, on the repeated ones, there seemed some relationship between the morphological change or stability of cisterns around the brain stem and clinical course or prognosis. (J.P.N.)

Pulsative hematoma: A penile fracture complication  

Directory of Open Access Journals (Sweden)

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.

Rectus sheath hematoma: three case reports  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Rectus sheath hematoma is an uncommon cause of acute abdominal pain. It is an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. It could occur spontaneously or after trauma. They are usually located infraumblically and often misdiagnosed as acute abdomen, inflammatory diseases or tumours of the abdomen. Case presentation We reported three cases of rectus sheath hematoma presenting with a mass in the abdomen and diagnosed by computerized tomography. The patients recovered uneventfully after bed rest, intravenous fluid replacement, blood transfusion and analgesic treatment. Conclusion Rectus sheath hematoma is a rarely seen pathology often misdiagnosed as acute abdomen that may lead to unnecessary laparotomies. Computerized tomography must be chosen for definitive diagnosis since ultrasonography is subject to error due to misinterpretation of the images. Main therapy is conservative management.

Neurosurgic treatment of spontaneous and traumatic intracerebral hematomas  

Directory of Open Access Journals (Sweden)

Full Text Available In the period from 01.01.2000 until 31.12.2002 34 patients with spontaneous intracerebral hematoma (ICH and with deeply disturbed state of consciousness were operated in the Department of neurosurgery of the Urgent Center, Clinical Center of Serbia. In all operated patients the indication for surgery was given on the basis of CT scan of the brain, state of consciousness, defined Glasgow coma score (GCS and neurological status, but due to existing or threatening incarceration not even one patient was submitted to angiography of the blood vessels at the cerebral base, thus preoperatively we did not know the cause of the hemorrhage. Of 34 operated patients 22 or 64.7% died, and 12 or 35.3% survived. 14 patients were in the deepest phase of coma, where the preoperative GCS is from 3 to 5 points, and in the postoperative course only one survived, aged 25. The other survivors had somewhat less disturbed state of consciousness, they also were younger, CT scan of the brain was without blood in the chamber system. In the same period, in the Department of Neurosurgery of the Urgent Center, Clinical Center of Serbia 43 patients with traumatic intracerebral hematoma (TIH were operated; 9 patients survived, 34 died. Only 4 patients had acute TIH. All of them were in the terminal stage of incarceration, and despite being immediately submitted to surgery all of them died. The remaining 39 patients had, the so called delayed TIH where the secondary CT scan of the brain showed development of the traumatic intracerebral haematoma that was not verified on the incipient scanner. Indication for a repeated CT scan was given in 19 patients due to focal or general neurological deterioration. However in 20 patients subsequent neurological disturbances were not registered. Those that survived were younger patients, and they were not in the deepest stage of coma, most often they had a temporal localization of hematoma.

Disturbance caused by varying propagation delay in non-occluding hearing aid fittings.  

Science.gov (United States)

The disturbance caused by various short propagation delays to the perception of external sounds and own voice for a non-occluding hearing aid was investigated. Ten normal-hearing and 10 mildly hearing-impaired individuals listened to external sounds and their own voice while wearing non-occluding devices providing 10dB of linear gain. Participants rated the disturbance caused by delays of 2, 4 and 10ms to music, running speech, and their own voices. The results indicated greater disturbance for the longest delay for both subject groups when judging own voice, with the ratings of the hearing-impaired participants being lowest. Normal-hearing participants also judged the 10-ms delay as more disturbing for the external sounds. Owing to the listening conditions with constant gain from 800Hz and above, the results apply directly only to this experiment. Disturbance ratings for all delays were low, which suggests that any of those tested would be acceptable for this application. PMID:15724524

Arachnoid cysts with subdural hematoma or intracystic hemorrhage in children.  

Science.gov (United States)

Arachnoid cyst (AC) is a common congenital intracranial lesion in children. It may be complicated by subdural hematoma (SDH) and intracystic hemorrhage (ICH) to cause intracranial hypertension after minor head injury or spontaneously. However, because most bleeding after trauma is delayed, it is often overlooked. At the same time, it remains controversial for treatment of ACs complicated with SDH and ICH. So far, it lacks review, especially for pediatric patients who have ACs with SDH or ICH. Here, we report 3 pediatric cases in our department from 2010 to 2011. At the same time, we review 41 pediatric patients reported in the last 20 years. We conclude that a child with AC should be regularly followed up after minor head injury, and that therapy for children with complicated ACs should be more aggressive than for adults. The cyst wall should be resected, and communication between cyst and cerebral cistern should be established. PMID:24786991

Scientific Electronic Library Online (English)

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

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

Science.gov (United States)

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.

Postoperative CT appearance in chronic subdural hematomas  

International Nuclear Information System (INIS)

Postoperative CT appearances in 65 cases of chronic subdural hematomas were evaluated in terms of patient's age, preoperative neurological symptoms and CT findings, final outcomes, and so on. All of the cases were treated with trepanation and irrigation. CT appearances were divided into four different types as follows; Type Ia: No abnormal findings in the subdural sapce, Type Ib: The same as above except for a linear high density suggestive of thickened outer membrane, Type II: Persistence subdural fluid collection and widened cortical sulci which indicate underlining brain atrophy, Type III: Remaining hematoma and/or density changes during follow-up period. Although the mean age of the patients in type Ib was higher than those in type Ia and reexpansion of the brain appear to delay in type Ib and preoperative CT in type Ib tended to show mixed density, final outcome in both groups were excellent. Characteristics in type II were that most of cases were in the eighth decade, preceding head injury was unclear, preoperative psychiatric symptoms and disturbance of consciousness were common and postoperative improvement of the symptoms was not satisfactory compared to other types. Aged patients as in type Ib and type II and thick hematomas of over 2 cm depth with mixed or high density tended to show type III postoperatively. All of the nine patients who required reoperation were included in this type. The present study indicates that thick hematomas with sizable mass effecat thick hematomas with sizable mass effect and mixed or high density in the aged must be carefully treated, such as with placement of the subdural drainage or keeping the patient in the Trendelenburg position, to facilitate postoperative reexpansion of the brain.

Postoperative spinal epidural hematoma resulting in cauda equina syndrome: a case report and review of the literature  

Science.gov (United States)

Spinal epidural hematoma is a well known complication of spinal surgery. Clinically insignificant small epidural hematomas develop in most spinal surgeries following laminectomy. However, the incidence of clinically significant postoperative spinal epidural hematomas that result in neurological deficits is extremely rare. In this report, we present a 33-year-old female patient whose spinal surgery resulted in postoperative spinal epidural hematoma. She was diagnosed with lumbar disc disease and underwent hemipartial lumbar laminectomy and discectomy. After twelve hours postoperation, her neurologic status deteriorated and cauda equina syndrome with acute spinal epidural hematoma was identified. She was immediately treated with surgical decompression and evacuation of the hematoma. The incidence of epidural hematoma after spinal surgery is rare, but very serious complication. Spinal epidural hematomas can cause significant spinal cord and cauda equina compression, requiring surgical intervention. Once diagnosed, the patient should immediately undergo emergency surgical exploration and evacuation of the hematoma. PMID:19830087

Hyperglycaemia and ketosis in a non-diabetic patient--an unusual cause of delayed recovery.  

Science.gov (United States)

We report a case of hyperglycaemia and ketosis developing in a non-diabetic patient who underwent a neurosurgical procedure under general anaesthesia. A 52-year-old non-diabetic female patient underwent excision of acoustic neuroma under general anaesthesia. Pancreatic function was not disturbed and she received a single dose of dexamethasone (8 mg) and paracetamol (1 g). Delayed recovery from anaesthesia occurred. On investigation, she was found to have hyperglycaemia and ketosis. She was further managed on the line of diabetic ketoacidosis. After 24 hours, when blood glucose had normalised and ketosis abated, she could be weaned from mechanical ventilation and extubated. The patient did not receive any drugs known to cause such a condition. To the best of our knowledge, hyperglycaemia and ketosis developing in a non-diabetic patient causing delayed recovery and extubation is here reported for the first time. PMID:25078770

Causes of delay in proper treatment of patients with undescended testis  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Undescended testis (UDT is the most common endocrine disorder in male children. Delayed diagnosis and treatment of UDT lead to complications such as infertility, malignancy and testis rotation. Objective: The aim of this study was to evaluate the causes of delay in proper treatment of patients with undescended testis in our population.Materials and Methods: An observational, descriptive, cross sectional study of 143 male patients, who applied to Shahid Sadoughi University Hospitals for orchiopexy operation was performed. The maximum recommended age for orchiopexy was 18 months.Results: The mean age at referral was 5.34 years. Only 44 (30.8% cases were operated on before the age of 18 months.

Causes of delay in proper treatment of patients with undescended testis  

Science.gov (United States)

Background: Undescended testis (UDT) is the most common endocrine disorder in male children. Delayed diagnosis and treatment of UDT lead to complications such as infertility, malignancy and testis rotation. Objective: The aim of this study was to evaluate the causes of delay in proper treatment of patients with undescended testis in our population. Materials and Methods: An observational, descriptive, cross sectional study of 143 male patients, who applied to Shahid Sadoughi University Hospitals for orchiopexy operation was performed. The maximum recommended age for orchiopexy was 18 months. Results: The mean age at referral was 5.34 years. Only 44 (30.8%) cases were operated on before the age of 18 months. The most common reasons of delay in treatment were absence of early diagnose (42.5%), parent's unawareness of surgery necessity and its complications associated (33.7%) and parent's disregard (23.5%). Only 19.6% of patients were diagnosed at born in the hospital. 49% of parents had the correct information for proper operation age and 40.6% of them had enough information about necessity of surgery and side effects of disease. Parent’s literacy, place of living and type of cryptorchidism had no significant relation with delay diagnosis (p> 0.05). Conclusion: These results revealed that late diagnosis by physician and lack of insight of parents are the main reasons in delayed diagnosis and treatment of UDT. Therefore, education of parents and careful physical examination of the babies at birth and regular follow-up until 18 months can prevent the delay in diagnosis.

Hematoma subdural crônico tratamento cirúrgico e resultados em 96 pacientes operados / Chronic subdural hematoma: surgical treatment and results in 96 operated patients  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Os autores apresentam os resultados cirúrgicos de 96 casos de hematoma subdural crônico operados por meio de orifícios de trépano ou pequenas trefinas: 78 pacientes (81,3%) foram considerados curados, 6 (6,2%) apresentaram seqüelas e 12 (12,5%) faleceram. Os óbitos de natureza neurocirúrgica foram r [...] elacionados à intensidade do comprometimento neurológico por ocasião da cirurgia. A idade avançada associada à presença de doenças sistêmicas também teve influência na mortalidade. Seqüelas neurológicas foram observadas principalmente em pacientes submetidos a reoperações por reacúmulo do hematoma e em portadores de lesões bilaterais. Os autores chamam a atenção para a ocorrência de hipotensão intracraniana associada a colapso cerebral. A importância do diagnóstico precoce e cirurgia imediata são enfatizadas. Abstract in english Ninety-six patients with chronic subdural hematoma were treated surgically and their clinical features presented in detail. Carotid angiography gave the correct diagnosis in all patients. CT scan was performed in 38 and was diagnostic in 92.1% of the cases. The clots were removed through burr-holes [...] or small trephines: 78 (81.3%) patients were cured, 6 (6.2%) had permanent disabilities and 12 (12.5%) died. Operative mortality was related to the degree of neurological impairment, advanced age and systemic diseases. Neurologic sequelae were mostly related to reoperations due to recurrence of the hematoma and bilateral clots, as well. 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.

A new technique using fibrin glue in the management of auricular hematoma.  

Science.gov (United States)

: This study aims to describe a new technique for the management of auricular hematoma using fibrin glue. Five difficult cases of auricular hematoma were managed using this technique, including 2 recurrent and 3 delayed presentations. After skin preparation and local anesthetic, an incision was made, the hematoma was evacuated, and the cavity was washed out with saline. Fibrin glue was applied liberally; a dental roll pressure dressing was applied and secured with a prolene bead suture. The patients were given a course of oral antibiotic and reviewed after 5 days for removal of the external dressing. They were later assessed to exclude re-accumulation of the hematoma. All patients had complete resolution of the hematoma without re-accumulation; they were satisfied with the cosmetic results and experienced no complications. This case series provides evidence that fibrin glue is effective in the management of auricular hematoma. Larger studies may provide further evidence of the effectiveness of this new technique.

Microwave hematoma detector  

Science.gov (United States)

The Microwave Hematoma Detector is a non-invasive device designed to detect and localize blood pooling and clots near the outer surface of the body. While being geared towards finding sub-dural and epi-dural hematomas, the device can be used to detect blood pooling anywhere near the surface of the body. Modified versions of the device can also detect pneumothorax, organ hemorrhage, atherosclerotic plaque in the carotid arteries, evaluate perfusion (blood flow) at or near the body surface, body tissue damage at or near the surface (especially for burn assessment) and be used in a number of NDE applications. The device is based on low power pulsed microwave technology combined with a specialized antenna, signal processing/recognition algorithms and a disposable cap worn by the patient which will facilitate accurate mapping of the brain and proper function of the instrument. The invention may be used for rapid, non-invasive detection of sub-dural or epi-dural hematoma in human or animal patients, detection of hemorrhage within approximately 5 cm of the outer surface anywhere on a patient's body.

Chronic subdural hematoma  

International Nuclear Information System (INIS)

Recently much attention has been paid once again to etiology of chronic subdural hematoma since the appearance of computed tomography (CT). Authors examined 1824 head injury cases by CT from January 1977 to September 1979. Among them, there are 40 cases (they were all over 16 years old) whose CT showed frontal extracerebral low density area. The low density area which is considered to be so-called fluid collection could be classified into four types (type I to IV). In two cases of those 40 cases (5%), the low density area changed into high density area which seemed to be hemorrhage. The 2 cases were diagnosed to be chronic subdural hematoma and proved surgery. The change of density on CT developed only from type I (the brain surface looks smooth and sulci are not recognized beneath the low density area). The change of density, occurred in 2 cases among 24 cases of type I (8.3%), was recognized about 2 months after the head injury. This fact is compatible with the report by Yamada et al. (1979). Thus, when CT after the head injury shows frontal extracerebral low density area of type I, the case may develop to chronic subdural hematoma about 2 months after the head injury. Therefore, careful observation should be needed especially during this period after the head injury. (author)

Root Cause Analysis Reports Help Identify Common Factors In Delayed Diagnosis And Treatment Of Outpatients  

Science.gov (United States)

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.

Two cases of subdural hematoma with niveau formation on CT  

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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.

Retroperitoneal and rectus sheath hematomas.  

Science.gov (United States)

The retroperitoneum is rich in vascular structures and can harbor large hematomas, traumatic or spontaneous. The management of retroperitoneal hematomas depends on the mechanism of injury and whether they are pulsatile/expanding. Rectus sheath hematomas are uncommon abdominal wall hematomas secondary to trauma to the epigastric arteries of the rectus muscle. The common risk factors include anticoagulation, strenuous exercise, coughing, coagulation disorders, and invasive procedures on/through the abdominal wall. The management is largely supportive, with the reversal of anticoagulation and transfusions; angioembolization may be necessary. PMID:24267499

Habitat fragmentation causes immediate and time-delayed biodiversity loss at different trophic levels.  

Science.gov (United States)

Intensification or abandonment of agricultural land use has led to a severe decline of semi-natural habitats across Europe. This can cause immediate loss of species but also time-delayed extinctions, known as the extinction debt. In a pan-European study of 147 fragmented grassland remnants, we found differences in the extinction debt of species from different trophic levels. Present-day species richness of long-lived vascular plant specialists was better explained by past than current landscape patterns, indicating an extinction debt. In contrast, short-lived butterfly specialists showed no evidence for an extinction debt at a time scale of c. 40 years. Our results indicate that management strategies maintaining the status quo of fragmented habitats are insufficient, as time-delayed extinctions and associated co-extinctions will lead to further biodiversity loss in the future.

Spontaneous intracranial extradural hematoma: Case report and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Spontaneous extradural hematoma (EDH is an uncommon form of intracranial hematoma and is caused by the adjacent sinus and otic infections, dural vascular malformations and disorders of blood coagulation. We report spontaneous EDH in a 54-year old women with chronic kidney disease (CKD on intermittent hemodialysis. She was successfully managed by conservative treatment. The EDH in her was probably related to the coagulation abnormalities associated with CKD, hemodialysis or heparin use during the dialysis.

Spinal epidural hematomas  

DEFF Research Database (Denmark)

During the period 1943-1985 six patients were operated for spinal epidural hematomas at the department of neurosurgery of the University Hospital of Arhus. It is essential to perform acute laminectomy in case of rapidly increasing neurological symptoms. In the case of slowly increasing symptoms operation may provide a good result even if it is performed a week after the onset of symptoms. It is important to watch patients with fracture/dislocations of the spine closely during the first weeks after a trauma. If they develop neurological symptoms the patients should immediately be transferred to the department of neurosurgery with a view of

Mfn2 downregulation in excitotoxicity causes mitochondrial dysfunction and delayed neuronal death.  

Science.gov (United States)

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

Assessment of Influential Causes of Construction Project Delay in Malaysian Private Housing from Developer’s Viewpoint  

Directory of Open Access Journals (Sweden)

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

Causes of Delay in Patient Triage in the Emergency Departments of Tabriz Hospitals  

Directory of Open Access Journals (Sweden)

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

Muscle hematoma: A critically important complication of alcoholic liver cirrhosis  

Directory of Open Access Journals (Sweden)

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.

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

LENUS (Irish Health Repository)

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.

A Case of Delayed Flare-up Allergic Dermatitis Caused by Jellyfish Sting.  

Science.gov (United States)

A 7-year-old boy, taking lessons at a yacht school at Enoshima in Kanagawa prefecture in Japan, recognized a linear eruption on his left lower leg during practice in August 2012. As it gradually enlarged, he visited a local medical clinic. The eruption initially improved with topical treatment but exacerbated in October of the same year. Although topical treatment was started again, there was minimal improvement, so the patient visited our hospital in December. At his first visit, he had a hard linear nodule on his left lower leg, and papules with excoriation were scattered over the lower limbs. Considering eczema, topical steroid treatment and occlusive dressing technique were started but the nodule remained. Based on the clinical course, clinical features, and laboratory findings, the lesion was considered to be delayed flare-up allergic dermatitis caused by a jellyfish sting [1]. PMID:25248421

Mutations in TRNT1 cause congenital sideroblastic anemia with immunodeficiency, fevers, and developmental delay (SIFD).  

Science.gov (United States)

Mutations in genes encoding proteins that are involved in mitochondrial heme synthesis, iron-sulfur cluster biogenesis, and mitochondrial protein synthesis have previously been implicated in the pathogenesis of the congenital sideroblastic anemias (CSAs). We recently described a syndromic form of CSA associated with B-cell immunodeficiency, periodic fevers, and developmental delay (SIFD). Here we demonstrate that SIFD is caused by biallelic mutations in TRNT1, the gene encoding the CCA-adding enzyme essential for maturation of both nuclear and mitochondrial transfer RNAs. Using budding yeast lacking the TRNT1 homolog, CCA1, we confirm that the patient-associated TRNT1 mutations result in partial loss of function of TRNT1 and lead to metabolic defects in both the mitochondria and cytosol, which can account for the phenotypic pleiotropy.

Bilateral Iliopsoas Hematomas under Sedation:A Complication of Postoperative Therapy after Coronary Artery Bypass Grafting  

Directory of Open Access Journals (Sweden)

Full Text Available We report a case of bilateral iliopsoas hematomas that occurred during postoperative therapy after coronary artery bypass grafting (CABG. An 81-year-old woman receiving anticoagulant and antiplatelet therapies under sedation after CABG developed sudden anemia and went into shock. Abdominal ultrasonography showed a right retroperitoneal hematoma. She improved gradually with conservative treatment. Many patients with an iliopsoas hematoma complain of low-abdominal pain or femoral neuropathy, but such local signs may be absent under sedation. In anticoagulant and antiplatelet therapies under sedation, when the cause of anemia and shock is not clear, we should suspect peritoneal hematoma and examine the peritoneal space.

Spontaneous intraorbital hematoma: case report  

Directory of Open Access Journals (Sweden)

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

Fuzzy Assessment of Causes of Time Overrun (Delays in Iran`s Dam Construction Projects  

Directory of Open Access Journals (Sweden)

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.

Tight Skin 2 Mice Exhibit Delayed Wound Healing Caused by Increased Elastic Fibers in Fibrotic Skin  

Science.gov (United States)

Rationale: The Tight Skin 2 (Tsk2) mouse model of systemic sclerosis (SSc) has many features of human disease, including tight skin, excessive collagen deposition, alterations in the extracellular matrix (ECM), increased elastic fibers, and occurrence of antinuclear antibodies with age. A tight skin phenotype is observed by 2 weeks of age, but measurable skin fibrosis is only apparent at 10 weeks. We completed a series of wound healing experiments to determine how fibrosis affects wound healing in Tsk2/+ mice compared with their wild-type (WT) littermates. Method: We performed these experiments by introducing four 4?mm biopsy punched wounds on the back of each mouse, ventral of the midline, and observed wound healing over 10 days. Tsk2/+ mice showed significantly delayed wound healing and increased wound size compared with the WT littermates at both 5 and 10 weeks of age. We explored the potential sources of this response by wounding Tsk2/+ mice that were genetically deficient either for the NLRP3 inflammasome (a known fibrosis mediator), or for elastic fibers in the skin, using a fibulin-5 knockout. Conclusion: We found that the loss of elastic fibers restores normal wound healing in the Tsk2/+ mouse and that the loss of the NLRP3 inflammasome had no effect. We conclude that elastic fiber dysregulation is the primary cause of delayed wound healing in the Tsk2/+ mouse and therapies that promote collagen deposition in the tissue matrix in the absence of elastin deposition might be beneficial in promoting wound healing in SSc and other diseases.

Acute tentorial subdural hematoma as a false-positive in indium-111 leukocyte scintigraphy  

International Nuclear Information System (INIS)

A case of acute tentorial subdural hematoma detected by In-111 leukocyte scintigraphy and confirmed by CT brain scan is herein described. White blood cells are an integral part of the blood pool and labeled white cells freely leave the intravascular space in case of active bleeding. Acute hemorrhage and hematoma can thus be a cause of a false-positive study

On the differential diagnosis of the abdominal aorta aneurysm and retroperitoneal paraaortal hematoma  

International Nuclear Information System (INIS)

Chronic retroperitoneal paraaortal hematoma appeared to be a rare disease. Paraaortal hematoma should be differentiated from abdomen aorta aneurysm and retroperitoneal tumor, for it requires no surgical intervention. Computerized tomography CT was shown to be the most sensitive method in differential diagnosis. CT with intravenous contrast intensification displayed complete information on aorta size, its aneurysms, extention of the disease, degree of dissemination into adjacent blood vessels and tissues. Retention of contrast media in the vessels occurred with 5 min delay and the blood was shown to free from the contrast substance up to that moment. The phenomenon permitted to distinguish thrombosed aneurysm from paraaortal tumor or hematoma

In utero protein restriction causes growth delay and alters sperm parameters in adult male rats  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Recent studies have supported the concept of "fetal programming" which suggests that during the intrauterine development the fetus may be programmed to develop diseases in adulthood. The possible effects of in utero protein restriction on sexual development of rat male offspring were evaluated in the present study. Methods Pregnant Wistar rats were divided into two experimental groups: one group treated with standard chow (SC, n = 8, 17% protein and the other group treated with hypoproteic chow (HC, n = 10, 6% protein throughout gestation. After gestation the two experimental groups received standard chow. To evaluate the possible late reproductive effects of in utero protein restriction, the male offspring of both groups were assessed at different phases of sexual development: prepubertal (30 days old; peripubertal (60 days old; adult (90 days old. Student's t-test and Mann-Whitney test were utilized. Differences were considered significant when p Results We found that in utero protein restriction reduced the body weight of male pups on the first postnatal day and during the different sexual development phases (prepubertal, peripubertal and adult. During adulthood, Sertoli cell number, sperm motility and sperm counts in the testis and epididymal cauda were also reduced in HC. Furthermore, the numbers of sperm presenting morphological abnormalities and cytoplasmic drop retention were higher in HC. Conclusions In conclusion, in utero protein restriction, under these experimental conditions, causes growth delay and alters male reproductive-system programming in rats, suggesting impairment of sperm quality in adulthood.

Spinal Intradural Hematoma and Permanent Paraparesis after a Lumboperitoneal Shunt Operation: An Unusual Complication  

Science.gov (United States)

Pseudotumor cerebri is a condition of increased intracranial pressure in the absence of clinical, laboratory or radiological pathology. Spinal intradural hematoma formation after lumboperitoneal shunt (LPS) implantation is very rare, but it can cause sudden and serious deterioration. In this report, we present a patient who developed an intradural hematoma following LPS operation. A 27-year-old male patient suffering from headaches and progressive vision loss was diagnosed with pseudotumor cerebri. He underwent LPS operation in January 2009. Four hours after the operation, he developed urinary and fecal incontinence with paraparesis (1/5). Lumbar magnetic resonance imaging identified an intradural hematoma at the level of L2-L3, and he was reoperated. The intradural hematoma was removed. Physical therapy was started because of paraparesis. Two months later, the patient's muscle strength had increased to 3/5. Surgeons must remember that, LPS implantation can cause a spinal intradural hematoma in a small percentage of patients, with catastrophic results. PMID:25187872

Whole spontaneous spinal epidural hematoma.  

Science.gov (United States)

A 26-year-old male who had no underlying disease, including coagulopathy, underwent thoracotomy and bleeding control due to hemothorax. On the fifth postoperative day, paralysis of both lower limbs occurred. Urgent spine magnetic resonance imaging showed a massive anterior spinal epidural hematoma from C2 to L1 level with different signal intensities, which was suspected to be staged hemorrhage. Hematoma evacuation with decompressive laminectomy was performed. The patient's neurologic deterioration was recovered immediately, and he was discharged without neurological deficits. A drug history of naftazone, which could induce a drug-induced platelet dysfunction, was revealed retrospectively. To our knowledge, this is the first report of whole spontaneous spinal epidural hematoma in a young patient, with a history of hemorrhoid medication. PMID:24967052

Spontaneous retropharynegeal hematoma: A case report and literature overview  

International Nuclear Information System (INIS)

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.

Inactivation of IL11 signaling causes craniosynostosis, delayed tooth eruption, and supernumerary teeth  

DEFF Research Database (Denmark)

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.

Spontaneous spinal subdural hematoma concurrent with cranial subdural hematoma.  

Science.gov (United States)

A 39-year old female presented with chronic spinal subdural hematoma manifesting as low back pain and radiating pain from both legs. Magnetic resonance imaging (MRI) showed spinal subdural hematoma (SDH) extending from L4 to S2 leading to severe central spinal canal stenosis. One day after admission, she complained of nausea and severe headache. Computed tomography of the brain revealed chronic SDH associated with midline shift. Intracranial chronic SDH was evacuated through two burr holes. Back pain and radiating leg pain derived from the spinal SDH diminished about 2 weeks after admission and spinal SDH was completely resolved on MRI obtained 3 months after onset. Physicians should be aware of such a condition and check the possibility of concurrent cranial SDH in patients with spinal SDH, especially with non-traumatic origin. PMID:24044087

Renal Artery Embolization of Perirenal Hematoma in Hemorrhagic Fever with Renal Syndrome: A Case Report  

International Nuclear Information System (INIS)

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

Magnetic resonance imaging in chronic subdural hematomas of early stages  

International Nuclear Information System (INIS)

The characteristic findings to distinguish chronic subdural hematomas of early stages from subdural CSF collections or enlarged subarachnoid spaces, was assessed by magnetic resonance imagings (MRI). Three sets of MRI, pre- and post-contrast as well as delayed post-contrast T1-weighted coronal images were obtained in 20 cases, in which low intensity subdural spaces were observed in 6 on the right, in 5 on the left and 9 bilaterally. The characteristic findings observed were as follows: a low signal intensity band between low intensity subdural space and cerebral surface at the precontrast MRI; linear enhancement at the outer surface of low intensity space at postcontrast MRI; and enhancement of the low intensity space at the delayed MRI. A combination of more than 2 of the above-mentioned findings was noted in 24 out of 29 low intensity spaces, 7 of which were confirmed by surgery as chronic subdural hematomas with outer membranes. In the remaining 17, low intensity spaces spontaneously regressed in 10, and increased their intensity and/or changed their sizes in 7. This data was obtained from follow-up MRI's. Such a combination in the initial MRI's may indicate developing chronic subdural hematomas. In 5 out of 29 low intensity spaces, neither intensity nor size changed, nor did enhancement show in delayed imagings in the follow-up MRI's, which may strongly suggest either subdural CSF collections or enlarged subarachnoid spaces. In conclusion, the low intenhnoid spaces. In conclusion, the low intensity band is speculated to be subarachnoid space shown up secondarily by the relative increase of intensity in the low intensity space; the linear enhancement is thought to be outer membrane formation, and the delayed-enhancement of low intensity spaces may be extravasation of contrast media from the outer membrane.

Mechanical tracheal obstruction due to an intramural esophageal hematoma following endoscopic variceal sclerotherapy.  

Science.gov (United States)

Endoscopic injection sclerotherapy is widely used as treatment for bleeding esophageal varices. Esophageal intramural hematoma is a rare complication following endoscopic injection sclerotherapy. Patients present with pain and dysphagia due to esophageal obstruction. We present the first reported case of respiratory failure resulting from an intramural hematoma causing posterior tracheobronchial compression. Although patients with alcoholic cirrhosis and bleeding varices requiring respiratory support generally have a poor prognosis this may be an occasion when ventilatory support may be expected to be easily withdrawn after hematoma resolution.

Computerized tomography in chronic subdural hematoma  

International Nuclear Information System (INIS)

In this report, the computerized tomography (CT) of chronic subdural hematoma was studied. Our experience was based on 22 patients with chronic subdural hematoma, verified by surgery. The results of the analysis of 16 cases excluded infant cases and post-operative cases. (1) In 8 cases, the locations of the hematoma were bilateral, and in 8 cases, unilateral. (2) The CT findings of the hematomas were classified into 4 types: low density (9 cases), iso-density (2 cases), mixed density (2 cases), and high density (3 cases). (3) Contrast enhancement in the capsule and the content of hematoma was indicated by the Marginal Curve. In infant cases (4), it is difficult to diagnose by the CT scan alone. We concluded, however, that CT was very useful in diagnosing chronic subdural hematoma. (author)

Endovascular treatment of an acute ascending aortic intramural hematoma?  

Science.gov (United States)

INTRODUCTION Herein, we present a case of an elderly gentleman who presented with an extensive intramural hematoma of the aorta which was treated with a percutaneous placement of an endovascular stent. PRESENTATION OF CASE A 79-year-old male with a history of hypertension presented to the emergency department because of sudden onset of substernal chest pain radiating to his back. A chest computerized tomography scan was performed that demonstrated a Type A aortic wall intramural hematoma involving the arch and ascending aorta dissecting both antegrade and retrograde from a penetrating ulcer located in the descending aorta, immediately distal to the left subclavian artery. No dissection flap was noted. The patient opted for an endovascular approach. He was treated with the placement of a stent just distal to the left subclavian artery, with good results noted on follow-up exam performed 3 months later. DISCUSSION The treatment of a Type A IMH lacks consensus, but the majority do favor surgical management. The data are limited; however, there are reports of patients with Type A intramural hematoma treated with descending aortic endograft at the site of the culprit ulcerated plaque, with satisfactory results. CONCLUSION In a select group of patients, an endovascular approach for the treatment of a Type A aortic wall intramural hematoma caused by an ulcerated plaque may be a viable treatment option.

MR imaging and clinical findings of spontaneous spinal epidural hematoma  

Energy Technology Data Exchange (ETDEWEB)

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

Spontaneous Cervical Epidural Hematoma with Hemiparesis Mimicking Cerebral Stroke  

Science.gov (United States)

Aim. Spontaneous cervical epidural hematoma (SCEH) is defined as an epidural hematoma that does not have an etiological explanation. The most common site for SCEH is cervicothoracic area. Early diagnosis and treatment are important for prognosis and good results. In this paper, we aimed to present a case who complains of sudden weakness on right extremities imitating cerebral stroke and that neuroimaging reveals spontaneous cervical epidural hematoma. Case. A 72-year-old woman was admitted to our hospital with acute neck pain and loss of strength on right extremities. On neurological examination, the patient had right hemiparesis. PT, aPTT, and INR results were 50.5, 42.8, and 4.8, respectively. Cranial MRI was in normal limits. Spinal MRI revealed a lesion that extends from C4 to C7 located on the right side and compatible with epidural hematoma. The patient was operated after normalization of INR values. Conclusion. Even though SCEH is a rare condition, it can cause severe morbidity and mortality. Early diagnosis and treatment are quiet important for prognosis. SCEH can easily be mistaken for stroke as with other pathologies and this diagnosis should come to mind especially in patients who have diathesis of bleeding. PMID:25371831

Pelvic hematoma resulting in obstructive uropathy.  

Directory of Open Access Journals (Sweden)

The use of anticoagulants, for whatever indication, may carry a high risk of hematoma formation following surgery. Obstructive uropathy is a very rare but possible example of complication secondary to an extensive pelvic hematoma. We describe a case of a patient with rheumatic heart disease and aortic valve replacement, who developed a massive postoperative pelvic hematoma following bilateral tubal ligation, resulting in bilateral ureteric obstructions. This was treated with bilateral ureteric stent through cystoscopy.

Cervical spontaneous spinal epidural hematoma with internal jugular vein thrombosis.  

Science.gov (United States)

Spontaneous spinal epidural hematoma (SSEH) is a rare condition, and its etiology remains unclear. Spinal venous wall instability due to intravenous pressure changes and the resultant venous rupture seem to be the underlying pathophysiological mechanisms. Here, the authors report a case of posterior SSEH at the C3-5 level causing mild left hemiparesis in a previously healthy 56-year-old woman. Angiography performed at the time of admission showed left internal jugular vein (IJV) thrombotic occlusion and dilation of the surrounding venous plexus, strongly suggesting that these pathologies caused the SSEH. Furthermore, immediate MR imaging suggested severely impaired blood flow in the left IJV. The hematoma soon resolved after spontaneous IJV thrombolysis. The authors' radiological observations imply that idiopathic IJV thrombosis may cause cervical SSEH. PMID:21513425

Spontaneous rectus sheath hematoma: two variant cases.  

Science.gov (United States)

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

Computed tomography of isodense subdural hematomas  

International Nuclear Information System (INIS)

Most subdural hematomas with significant differed attenuation from that of adjacent brain tissue can be accurately diagnosed by CT. Difficulty arises when the hematoma is isodense that is exhibited similar attenuation to that of brain. Unilateral isodense subdural hematoma can be identified by indirect sign such as mass effect. Occasionally, the use of intravenous contrast material to aid in identifying isodense subdural hematomas has met with variable success. Moreover, bilateral isodense subdural hematoma may be more difficult. We therefore considered it of interest to evaluate the diagnostic efficiency of CT in isodense subdural hematomas. We have analysed 13 cases surgically provened cases of isodense subdural hematoma examined at Korea General Hospital from October 1981 to April 1982. The results were as follows: 1. One hundred twenty seven cases of subdural hematomas were studied by CT, 13 cases (10.2%) of which were isodense. 2. The age distribution was from 29 years to 69 years and mean age was 52 years. The sex ratio was 11 male to 2 female. 3. Seven (53.8%) of 13 cases has a history of head trauma. 4. The time interval which subdural hematoma became isodense was from 1 week to 4 months and peak time interval was from 1 week to 3 weeks. 5. The precontrast CT scan of isodense subdural hematoma appeared shifting of midline structure, compression and deformity of the ventricles in all 13 cases, effacement of cerebral sulci in 10 cases (76.9%) and dilatation of cci in 10 cases (76.9%) and dilatation of contralateral ventricles in 4 cases (30.8%). 6. The postcontrast CT scan demonstrated enhancement of the medial margin of the lession in 4 (30.8%) of 13 cases and displacement of cortical vein away from the inner table of the skull in 3 (23.1%) of 13 cases. 7. Bilateral isodense subdural hematomas were 2 (15.4%) of 13 cases

Extracerebral hematoma and parenchymal lesion in computerized tomography of pediatric patients with severe head injury  

International Nuclear Information System (INIS)

Fifty children (13 years of age or under) with acute, severe head injury were analyzed, with special reference to the relations between initial computerized tomography (CT) findings, clinical severity, and outcome. The severity and the outcome were evaluated using the Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS), respectively, adoption of GCS scoring being restricted to patients 3 years of age or over. Twenty-three patients (46 %) showed extracerebral hematomas. The most common extracerebral hematoma was the acute subdural hematoma, which comprised 24 % of the cases; epidural hematomas were found in 9 cases (18 %). These figures coincided with the reported results of adult cases in severe head injury. All the epidural hematoma cases showed ''normal'' parenchymal lesion, and carried less clinical severity and better outcome. This might suggest that more trivial injury would cause the epidural hematoma in children than in adults. Hemispheric swelling was commonly seen in patients with acute subdural hematoma and was generally associated with low GCS scores (mean 4.8) and poor outcome (63 % mortality). Compared with that in adults, hemorrhagic lesion in children was less often associated with extracerebral hematoma, and the outcome and severity of the cases with this lesion depended mainly on the multiplicity and the location of the hemorrhage. Eleven cases fulfilled the criteria of diffuse cerebral swelling, namely, slit-like ventricles and obliterated perimesencephalic cisterns, and only one had an associated subdural hematoma. Forty-two patients (84 %) achieved a good recovery or a moderate disability. None were severely disabled or vegetative, and the overall mortality rate was 16 %. Patients with GCS scores of 3 to 5 were uniformly poor in outcome (60 % of mortality), regardless of parenchymal lesions, whereas those with GCS scores of 6 to 8 had only 8 % mortality. (J.P.N.)

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.)

Search for Long-Lived Delayed Neutron Groups: Photofission Caused by Fission-Product Gamma-Rays  

International Nuclear Information System (INIS)

A search has been made for long-lived delayed neutron groups with half-lives greater than 55 s in the thermal neutron fission of 235U. The neutron counter used in these experiments was designed to allow one to distinguish between true delayed neutrons and neutrons produced by (?, n) reactions on D and Be impurities. The experimental results showed the existence of apparent delayed neutron groups with half-lives greater than 55 s and of very low intensity. These were shown to be neither true delayed neutrons, nor photoneutrons from D or Be but were prompt neutrons from the photofission of 238U and 235U. Photofission is produced by high energy ( > 4.5 MeV) gamma rays emitted from certain fission products. The intensity of the neutrons produced in this way decays with the half-lives of the fission products causing the photofission. The half-lives of the ''photofission groups'' were 3.1, 17 and 111 min, with absolute yields of 1 x 10-8, 1 x 10-11 and 2 x 10-12 neutrons/fission respectively, under the best conditions. By surrounding the irradiated uranium sample with large amounts of 238U, 235U or 239Pu, it was possible to obtain relative photofission cross-sections for these nuclides. The values obtained were: 1.0, 1.4 and 10.8 for 238U, 235U and 239Pu respectively, in agreement with known cross-sections. It is unlikely that photofission groups with t1/2 ? 3.1 min will, under any experimental or reactor conditions, be a significant fraction of the total delayed neutron yield. However, shorter-lived photofission groups (t1/2 239Pu, where the photofission cross-section is high and the delayed neutron yield is low compared to other nuclides. From the experimental results, upper limit values were calculated for the neutron branching ratios of 91Rb, 140Cs, 96Y, and 133Sb. These were: ? 0.7%, ? 0.1%, ? 5 x 10-6% and ? 3 x 10-6%, respectively. (author)

MRI findings of traumatic spinal subdural hematoma  

Energy Technology Data Exchange (ETDEWEB)

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

Autologous blood-clot embolisation of cavernosal artery pseudoaneurysm causing delayed high-flow priapism  

Science.gov (United States)

Summary Background: High-flow priapism is a rare condition characterized by a prolonged and painless erection. Since it may permanently impair erectile function, it must be managed and treated as soon as possible, in order to restore potency. The case we are presenting here was successfully treated by embolizing the penile artery using an autologous clot. Case Report: A case of delayed painless high-flow priapism that occured after blunt straddle-type perineal trauma, that was persistent for more than 30 days is being presented. Doppler ultrasonographic examination of the cavernosal artery revealed a 1.5 cm-diameter pseudoaneurysm at the right cavernosal artery, together with a high-velocity shunt between the two cavernous arteries. Extravasation from the proximal sites of both of the cavernous arteries and a right cavernosal artery pseudoaneurysm was detected on angiography. The patient was successfully treated by embolization of the penile artery with an autologous clot in two sessions with a 3-day interval. Conclusions: This experience along with a survey of the literature made us conclude that embolization of cavernous artery by means of an autologous clot is a very effective procedure and a method of choice for treatment of high-flow priapism and for restoration of penile erectile function. What makes our case even more interesting and important, is the fact that priapism of one month’s duration could well be treated by means of this method. PMID:23807886

Delayed feedback causes non-Markovian behavior of neuronal firing statistics  

CERN Document Server

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

Reduction of ARNT in myeloid cells causes immune suppression and delayed wound healing.  

Science.gov (United States)

Aryl hydrocarbon receptor nuclear translocator (ARNT) is a transcription factor that binds to partners to mediate responses to environmental signals. To investigate its role in the innate immune system, floxed ARNT mice were bred with lysozyme M-Cre recombinase animals to generate lysozyme M-ARNT (LAR) mice with reduced ARNT expression. Myeloid cells of LAR mice had altered mRNA expression and delayed wound healing. Interestingly, when the animals were rendered diabetic, the difference in wound healing between the LAR mice and their littermate controls was no longer present, suggesting that decreased myeloid cell ARNT function may be an important factor in impaired wound healing in diabetes. Deferoxamine (DFO) improves wound healing by increasing hypoxia-inducible factors, which require ARNT for function. DFO was not effective in wounds of LAR mice, again suggesting that myeloid cells are important for normal wound healing and for the full benefit of DFO. These findings suggest that myeloid ARNT is important for immune function and wound healing. Increasing ARNT and, more specifically, myeloid ARNT may be a therapeutic strategy to improve wound healing. PMID:24990649

Massive sublingual hematoma secondary to anticoagulant therapy complicated by a traumatic denture: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Sublingual hematoma secondary to excessive anticoagulation is a rare but potentially fatal condition, and few cases have been documented in the literature. Case presentation We report the case of a 73-year-old Caucasian woman who attended our Accident and Emergency department with massive sublingual hematoma causing superior displacement of the tongue. The condition was found to be the result of an elevated international normalized ratio, further complicated by a traumatic mandibular denture. Conclusions In summary, we recommend the immediate reversal of anticoagulation therapy on admission of patients with severe sublingual hematoma. We further advise surgical decompression/drainage if required and to continue meticulous monitoring. In all cases of early recognition of sublingual hematoma, prompt medical treatment and continuous clinical monitoring is essential, and may prevent the need for a surgical airway procedure.

Evaluation and establishment of a canine model of delayed splenic rupture using contrast-enhanced ultrasound.  

Science.gov (United States)

The aim of the present study was to establish a canine model of delayed splenic rupture (DSR). A total of 15 mongrel dogs were anesthetized and laparotomized. The hematomas were observed following an injection of heparin. The hematomas were ruptured. The severity of the spleen rupture was evaluated and the intra-abdominal free liquid was measured. The splenic hematomas in the dogs continued to form and the hematoma area gradually increased. The hematomas were ruptured after impacting the abdominal wall. The spleens were damaged, and conventional ultrasonography showed intra-abdominal free liquid. These conditions were demonstrated via computed tomography scanning. A DSR canine model was established successfully. PMID:22710316

Upper thoracic myelopathy caused by delayed neck extensor weakness in myotonic dystrophy.  

Science.gov (United States)

Myotonic dystrophy is the most common autosomal dominant myopathy in adults. Our patient, a 41 year-old female suffering from myotonic muscular dystrophy, developed upper thoracic myelopathy due to hypertrophy of the ligamentum flavum and the posterior longitudinal ligament. She had a typical hatchet face and ptosis with "head hanging forward" appearance caused by neck weakness. Motor weakness, sensory changes and severe pain below T4 level, along with urinary incontinence began 3 months ago. Genetic and electrodiagnostic studies revealed myotonic dystrophy type 1. Magnetic resonance imaging of the spine showed loss of cervical lordosis and spinal cord compression due to hypertrophied ligamentum flavum and posterior longitudinal ligament at T1 to T3 level. We concluded that her upper thoracic myelopathy was likely related to the thickness of the ligamentum flavum and posterior longitudinal ligament due to repetitive mechanical stress on her neck caused by neck muscle weakness with myotonic dystrophy.

Full thickness burn caused by exposure to giant hogweed: delayed presentation, histological features and surgical management.  

LENUS (Irish Health Repository)

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.

The bilateral isodense subdural hematoma on computerized tomographic scan.  

Science.gov (United States)

Blood causes striking changes on computerized tomography. However, chronic subdural hematomas may become isodense with brain and therefore not visible directly. Midline and ventricular displacement, effacement of cortical sulci, narrowing of white matter on one side, and ventricular distortion should suggest a unilateral isodense process. Bilateral isodense subdural hematomas pose a major problem on computerized tomography since there are no indications of a mass lesion. A negative report could lull the clinician into a false sense of security. In these cases, general disappearance of sulci and considerable narrowing of ventricles are helpful findings. A particularly important and overlooked sign is an abnormally decreased bicaudate cerebroventricular index. Above all, a high degree of suspicion is vital. PMID:444099

Age determination of soft tissue hematomas.  

Science.gov (United States)

In clinical forensic medicine, the estimation of the age of injuries such as externally visible subcutaneous hematomas is important for the reconstruction of violent events, particularly to include or exclude potential suspects. Since the estimation of the time of origin based on external inspection is unreliable, the aim of this study was to use contrast in MRI to develop an easy-to-use model for hematoma age estimation. In a longitudinal study, artificially created subcutaneous hematomas were repetitively imaged using MRI over a period of two weeks. The hemorrhages were created by injecting autologous blood into the subcutaneous tissue of the thigh in 20 healthy volunteers. For MRI, standard commercially available sequences, namely proton-density-weighted, T2 -weighted and inversion recovery sequences, were used. The hematomas' MRI data were analyzed regarding their contrast behavior using the most suitable sequences to derive a model allowing an objective estimation of the age of soft tissue hematomas. The Michelson contrast between hematoma and muscle in the proton-density-weighted sequence showed an exponentially decreasing behavior with a dynamic range of 0.6 and a maximum standard deviation of 0.1. The contrast of the inversion recovery sequences showed increasing characteristics and was hypointense for TI = 200ms and hyperintense for TI =1000ms. These sequences were used to create a contrast model. The cross-validation of the model finally yielded limits of agreement for hematoma age determination (corresponding to ±1.96 SD) of ±38.7h during the first three days and ±54 h for the entire investigation period. The developed model provides lookup tables which allow for the estimation of a hematoma's age given a single contrast measurement applicable by a radiologist or a forensic physician. This is a first step towards an accurate and objective dating method for subcutaneous hematomas, which will be particularly useful in child abuse. Copyright © 2014 John Wiley & Sons, Ltd.

Rapamycin treatment causes developmental delay, pigmentation defects, and gastrointestinal malformation on Xenopus embryogenesis  

International Nuclear Information System (INIS)

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

Spontaneous perforation of an intramural rectal hematoma: Report of a case  

Directory of Open Access Journals (Sweden)

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.

Surgical management of traumatic acute subdural hematoma in adults: a review.  

Science.gov (United States)

Traumatic acute subdural hematoma (ASDH) is a major clinical entity in traumatic brain injury (TBI). It acts as a space occupying lesion to increase intracranial pressure, and is often complicated by co-existing lesions, and is modified by cerebral blood flow (CBF) changes, coagulopathy, and delayed hematomas. Because of its complicated pathophysiology, the mortality of ASDH is still remaining high. In this review article, its epidemiology, pathophyiology, surgical treatment, and salvage ability are described. With regard to epidemiology, as the population ages, growing number of elderly patients with ASDH, especially patients with prehospital anticoagulant and antiplatelets, increase. Concerning pathophysiology, in addition to well-known initial intracranial hypertension and subsequent ischemia, delayed hyperemia/hyperperfusion, or delayed hematoma is being recognized frequently in recent years. However, optimal treatments for these delayed phenomenons have not been established yet. With regard to surgical procedures, all of craniotomy, decompressive craniectomy, and initial trephination strategies seem to be effective, but superiority of each procedure have not been established yet. Since Glasgow Coma Scale (GCS) scores, age, papillary reaction, and computed tomographic findings are strongly correlated to outcome, each factor has been investigated as an indicator of salvage ability. None of them, however, has been defined as such one. In future studies, epidemiological changes as population ages, management of delayed pathophysiology, superiority of each surgical procedures, and salvage ability should be addressed. PMID:25367584

4 cases of iliopsoas hematoma associated with hemophilia  

Energy Technology Data Exchange (ETDEWEB)

Four patients were diagnosed as having iliopsoas hematoma associated with hemophilia by CT scanning. The site and disappearance of hematoma were observed on CT. It was suggested that hematoma occurs inside the iliacus or posoas muscle in cases of iliopsoas hematoma complicated by hemophilia or coagulation and that it occurs in the pelvic wall of the iliacus muscle in cases of iliopsoas hematoma uncomplicated by coagulation abnormality.

Spontaneous disappearance of acute subdural hematoma on CT scan  

International Nuclear Information System (INIS)

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

Dengue Fever with rectus sheath hematoma: a case report.  

Science.gov (United States)

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

Common peroneal nerve palsy due to hematoma at the fibular neck.  

Science.gov (United States)

Common peroneal nerve palsy is an infrequent pathology mostly related to endogenous or exogenous compression. The exogenous compression is frequently related to trauma: knee fractures or hematoma arisen after a direct blow. Fractures may cause a direct lesion of the nerve; hematoma causes a compression of the nerve at the fibular neck causing pain and functional loss. Lesions of the common peroneal nerve can also be related to total knee arthroplasty. The clinical evaluation is characterized by muscle weakness with or without sensory abnormality. The etiopathogeneses of the compression have to be confirmed by ultrasound or magnetic resonance imaging before the surgical treatment. The purpose of this article is to describe a case of common peroneal nerve palsy due to a posttraumatic hematoma after a sport-related injury. We evaluated this case with dynamic ultrasound with good visualization of the morphology of the lesion and of the compression. PMID:23283631

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)

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

Nontraumatic spinal epidural hematomas. MR features  

Energy Technology Data Exchange (ETDEWEB)

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

Computer tomography of intracranial tumours and hematomas  

International Nuclear Information System (INIS)

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

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

Energy Technology Data Exchange (ETDEWEB)

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)

Atypical CT findings of acute epidural hematomas  

International Nuclear Information System (INIS)

One of the classic CT findings is characterized by a lenticular high density in acute epidural hematomas. However, several atypical CT findings in acute epidural hematomas have been reported lately. We have ourselves met three cases of acute epidural hematomas, in which there were low-or isodensity spots within typical high-density areas. Case 1: a 74-year-old male, a victim of a traffic accident, showing a high degree of anemia (Ht: 14%, Hb: 2.8 g/dl.) secondary to massive subcutaneous hemorrhage resulting from traumatic DIC. His CT, taken 12 hours after the head injury, disclosed bubble-like low density spots in a typical high-density area. Case 2: a 9-month-old baby boy, who had fallen to the ground from a height of 25 cm, was also anemic on admission (Ht: 17%, Hb: 5.2 g/dl.). An initial CT-scan, 7 hours after head injury, again disclosed a huge low density spot in the center of a typical high-density area. Case 3: an 11-year-old girl, involved in a car accident. A CT-scan, taken 4.5 hours after head injury, showed a low-density spot in the center of a high-density area. In her case, however, there was no evidence of significant anemia. In these three cases, the CT findings were close to one another in appearance, namely, classic lenticular high-density areas, spotted with round low-or isodensity areas within those hematomas. The causative factors have been thought be one of the following: a markedly low hemoglobin value, a time difference in the coagulation process within the same hematomas, or a possible leakage of CSF into the hematomas from a dural tear. It seemed that no single causative factor was responsible in these three cases; rather, it seems that multiple factors had progressed simultaneously. (author)

Hematoma retroperitoneal espontáneo: Caso clínico Spontaneous retroperitoneal hematoma: Report of one case  

Directory of Open Access Journals (Sweden)

Full Text Available Spontaneous retroperitoneal hematoma is a rare condition. We report a 78 year-old man with progressive pain in his right thigh and hip lasting one week. The pain subsequently was associated with abdominal pain in the right lower quadrant. Physical examination revealed pain to deep palpation of the area, associated with a diffuse positive rebound pain. An abdominal and pelvis CT scan showed an extensive mesenteric hematoma. During surgery, a large retroperitoneal encapsulated hematoma, without evidence of active bleeding, was found and drained. Pathology confirmed the diagnosis and was negative for cancer (RevMéd Chile 2007; 135:1044-7

A retropharyngeal-mediastinal hematoma with supraglottic and tracheal obstruction: The role of multidisciplinary airway management  

Directory of Open Access Journals (Sweden)

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.

Chronic spontaneous cervicothoracic epidural hematoma in an 8-month-old infant  

Directory of Open Access Journals (Sweden)

Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of cord compression in children, especially in infants. An 8-month-old infant was admitted to our hospital for a 40-day history of paraparesis in the lower extremities. This rapidly progressed to paraparesis with an inability to move the lower extremities. MRI of the cervicothoracic spine revealed an epidural mass with compression of the spinal cord. The infant underwent C7-T3 total laminectomies. The pathology and postoperative MRI confirmed spinal epidural hematoma from a vascular malformation. We present the case to highlight the significance of recognizing this chronic spontaneous spinal epidural hematoma and discuss the diagnosis, treatment options and prognosis.

FDG-PET imaging for chronic expanding hematoma in pelvis with massive bone destruction  

International Nuclear Information System (INIS)

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

Reducing the radiation-induced G2 delay causes HeLa cells to undergo apoptosis instead of mitotic death  

International Nuclear Information System (INIS)

Cells exposed to radiation may undergo death through apoptosis or mitotic death. HeLa cells predominantly undergo mitotic death after irradiation. Treatment of these cells with caffeine has been shown to shorten the G2 delay after irradiation, and to decrease their survival. The kinase inhibitor staurosporine also decreases the radiation-induced G2 delay in HeLa cells. Here we extend these findings to show that the decrease in radiation-induced G2 delay mediated by caffeine or staurosporine is accompanied by a shift in the pathway of cell death from mitotic death to apoptotic death. The increase in apoptosis is further accompanied by decreased clonogenic survival after irradiation. Based on these findings we propose the hypothesis that one mechanism of enhancing cell killing by radiation is to trigger apoptosis by decreasing the G2 delay induced by irradiation. (Author)

Contralateral acute subdural hematoma occurring after evacuation of subdural hematoma with coexistent contralateral subdural hygroma.  

Science.gov (United States)

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

Head trauma and CT with reference to epidural hematoma  

International Nuclear Information System (INIS)

Computed tomography (CT) is useful to detect lesions in patients with mild head trauma in its acute stage which may be followed by a lucid interval of hours to several days before exact diagnosis is made, or in serious patients with impairment in state of consciousness. Non-enhanced scan can determine the location of the lesion in 94% of patients with brain tumor, and enhanced scan can do in more than 98%. CT can reveal many anatomical changes due to trauma. Of these pathological changes, epidural hematoma is often caused by the damage of the middle meningeal artery or its branch. Therefore, CT should be performed if a bone-fracture line runs across the meningeal artery. CT is also applicable for the patients with some brain symptoms such as those who had not immediate post-traumatic unconsciousness but have developed impairment in state of consciousness after a lucid interval, or those who have persistent headache even if they have no impairment in stage of consciousness. In CT findings, the margin of hematoma and normal cerebral tissues is usually clear in acute causes but unclear in subacute cases. (Ueda, J.)

Type III Rectus Sheath Hematoma: A Case Report  

Directory of Open Access Journals (Sweden)

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.

Hematomas renales tras Litotricia Extracorpórea por Ondas de Choque: LEOCH / Renal hematomas after extracorporeal shock-wave lithotripsy: ESWL  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish 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.

Hematoma subdural crónico: Una enfermedad del adulto mayor Chronic subdural hematoma: a disease of elderly people  

Directory of Open Access Journals (Sweden)

Full Text Available The lack of specificity and heterogeneity of the clinical picture of chronic subdural hematoma, hampers its diagnosis. Aim: To report the experience of a Neurosurgical Service in chronic subdural hematoma. Patients and methods: One hundred patients (77 male, mean age 77±13 years with chronic subdural hematoma were analyzed. Results: The main clinical presentations were mental status changes (50% and progressive focal neurological deficit (46%. Five cases presented as a transient neurological deficit. All patients were treated with burr hole drainage. Thirteen had recurrence of the hematoma and they were reoperated. The surgical mortality was 3%. Eighty seven patients were followed for a mean of 66 months. Eighty one of these had a complete recovery, 6 had permanent neurological deficit and 2 of these were unable to care for themselves. Bad prognosis was associated with the absence of a previous trauma to explain the hematoma and symptoms of dementia as the clinical presentation. Conclusions: Most patients with chronic subdural hematoma treated with burr hole drainage have a good outcome (Rev Méd Chile 2003; 131: 177-82

Traumatic Posterior Fossa Epidural Hematomas and Their Complications  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Traumatic posterior fossa epidural hematomas (TPFEDH occur infrequently however their mortality and morbidity are higher than supratentorial epidural hematomas. Signs and symptoms may be silent or nonspecific, even though they may show rapid progression and deterioration from consciousness to coma, thus they would cause fatal results. Recently, practice of computerized tomography (CT has grown up and replaced the use of direct X-ray to detect calvarial fractures and other traumatic pathologies, therefore patients with posterior fossa trauma were diagnosed earlier.Material and Methods: We presented eight cases who suffered from TPFEDHs treated in our clinics between the years 2002 and 2006. Five cases were operated immediately however 3 cases were treated conservatively. One of the operated cases died immediately after surgery. Postoperative complications of cerebral sinus thrombosis and pseudomeningocele were observed in two cases. Alive cases were discharged a few days after surgery.Conclusion: Mortality decreases in TPFEDHs since they could be diagnosed earlier with widespread use of CT and treated successfully. In addition, it is easier to decide whether conservative or surgical therapy is efficient because CT findings should correlate with clinical findings. However, few complications such as cerebral sinus thrombosis and pseudomeningocele occur infrequently. Furthermore these cases must be monitored carefully during postoperative period for a new neurological finding.

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

Spontaneous spinal epidural hematoma in infancy: review of the literature and the "seventh" case report.  

Science.gov (United States)

Spontaneous spinal epidural hematomas (SSEH) are a rare cause of spinal cord compression in childhood and especially in infancy. We reviewed the literature and describe a case of an 8-month-old boy with a large spontaneous cervico-thoracic epidural hematoma. With this review we want to detail the importance of early investigation, diagnosis and treatment in infants with SSEH. In our case the infant presented with irritability and crying and an ascending paralysis within four days. Magnetic resonance imaging (MRI) of the spine demonstrated an extensive epidural hematoma between C5 and L1, serious medullar compression and secondary cervical and thoracic medullar edema and hydromyelia. An emergency laminectomy was performed with evacuation of a well organized hematoma. There was a partial recuperation of the neurologic symptoms. Based on the scarce literature which only concerns seven case reports, SSEH is a rare cause of spinal compression in infancy. The presentation is often not specific and neurological symptoms are often lacking in the beginning. However early diagnosis with MRI and prompt neurosurgical intervention are important to improve outcome. PMID:23786707

Groin hematoma after electrophysiological procedures-incidence and predisposing factors  

DEFF Research Database (Denmark)

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.

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)

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)

Ultrasonographic findings of psoas abscess and hematoma  

Energy Technology Data Exchange (ETDEWEB)

A retrospective analysis of the ultrasonographic findings of 9 cases tuberculous abscess, 5 cases of pyogenic abscess and 2 cases of hematoma of psoas and adjacent muscles was made. Fluid collection with or without internal echoes was seen in 12 cases out of total 16 cases. Other findings were 2 cases of only muscle swelling, 1 cases of highly echogenic mass-like appearance and 1 case of fluid collection with septae. Ultrasonography is considered an accurate method in identifying early pathologic changes of the psoas muscle and determining its extent, and in differentiating tumor from fluid collection of the psoas muscle. Authors dare to say that ultrasound examination is a procedure of choice in the diagnosis of psoas abscess and hematoma.

A new treatment for hypertensive intracerebral hematoma  

International Nuclear Information System (INIS)

Durining the last 2 years, 46 cases of hypertensive intracerebral hemorrhage in the basal ganglia were treated by CT guided stereotactic aspiration and their outcome was evaluated in terms of the rate of hematoma removal, the change of consciousness level and the recovery of motor and sensory functions. They are aged from 45 to 79 years old, the average 56, and aspirated 1 to 24 days after the onset, two third of them being within 1 week. The whole procedure was done in the CT room under direct CT guidance and by one trial. In putaminal type hemorrhage, the removed hematoma volumes ranged from 9 to 48 ml, average being 23.7 ml, in thalamic type from 5 to 29 ml, average being 15.5 ml. The average rate of removal was 81.1 % in 30 cases within 1 week. In most cases, preoperative consciousness was not severely disturbed, in putaminal type, 19 were alert or confused, 4 somnolent, 5 stuperous and in thalamic type, 6, 6, 3 respectively and 2 were semicomatous, one of them had herniation sign. In putaminal type all but 2 cases recovered to alert or confused state, the first one had postoperative bleeding and the other was already apallic preoperatively. In thalamic type, we lost 3 cases, 2 by gastrointestinal bleeding and 1 DIC, by rehemorrhage 2 months after the operation. All but one who was semicomatous preoperatively recovered to alertness. In motor function, some cases of the putaminal bleeding with intact internal capsule remained hemiplegic. On the other hand, most of the cases with partial destruction of the internal capsule on CT recovered well in both types of hematoma. Especially in thalamic type, only 2 had inability to walk durinig the follow-up period. In sensory function, two thirds of the cases recovered to almost normal level. CT guided stereotactic aspiration, therefore, can be evaluated as less invasive and more definitive treatment for intracerebral hematoma in the basal ganglia. (author)

Idiopathic adrenal hematoma masquerading as neoplasm.  

Science.gov (United States)

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.

Chronic expanding hematoma extending over multiple gluteal muscles associated with piriformis syndrome.  

Science.gov (United States)

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

Langerhans' cell histiocytosis presenting with an intracranial epidural hematoma  

International Nuclear Information System (INIS)

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

Role of CT in evaluation of iliopsoas hematomas in hemophiliacs  

International Nuclear Information System (INIS)

Four iliopsoas hematomas in hemophiliacs are reported, evaluating the diagnostic role of CT. The specificity of the method is stressed in showing the morphological and densitometric patterns, which allow to localize the hematoma, to state the originating structures, and follow its evolution. Comparing the obtained results to those found in literature, the authors suggest the use of CT in any hemophiliac in which a retroperitonal hematoma is suspected

[What causes self-control failure in delayed-cost dilemma: the role of affective expectancy and regulatory resource].  

Science.gov (United States)

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

Spontaneous spinal epidural hematoma inducing acute anterior spinal cord syndrome.  

Science.gov (United States)

Spontaneous spinal epidural hematoma (SSEH) is rare. Its etiology remains controversial; however, spinal venous wall susceptibility to intravenous pressure change and the resultant venous rupture seem to be involved. The authors report a case of SSEH dorsal to the spine producing acute anterior spinal cord syndrome. A posterior SSEH between the C-3 and T-5 levels caused progressive tetraparesis and the disappearance of superficial body sensation below the level of C-8, although deep sensation remained completely intact. This neurological false localizing sign seems to have resulted from counterforce by preexisting asymptomatic cervical intervertebral disc herniation at the C6-7 levels inducing direct pressure on the anterior spinal cord. This case is the first reported instance of posterior cervical SSEH manifesting acute anterior spinal cord syndrome as its false localizing sign. PMID:19558290

Abstract in english Background: Around 600 spinal epidural hematoma cases have been previously reported. Incidence of paraplegia after epidural anesthesia varies between 0,0005 and 0,02%. Several possible etiologies have been described in the literature, including surgery, trauma, anticoagulant therapy, arteriovenous m [...] alformations, pregnancy and lumbar puncture. Spinal and epidural anesthesic procedures represent the tenth most common cause. But in combination with anticoagulant therapy, the forementioned procedures increase its incidence until reaching the fifth most common etiological group. We report the case of an 80 year-old-man with a cervical epidural hematoma who had a good outcome with conservative management. Case report: 80 year-old-man that developed intense cervicalgia with lower limbs weakness showing complete paraplegia and arreflexia 2 hours after analgesic treatment with epidural cervical infiltration for cervicoartrosis. Cervical MRI showed epidural cervical hematoma between C4 and T1 levels. The patient is transferred to our facilities in order to perform surgery. But after showing fast recovery, medical conservative management was elected. After one month, the patient's condition has improved showing no neurological deficits and complete resorption is seen in MRI. Conclusions: Nowadays, trend is to perform surgery in patients with spinal hematoma and significant neurological deterioration during the first hours. However, good neurological outcomes can be achieved with conservative management, in well selected patients with non progressive, incomplete and partial deficits. Presently, we can not predict wich is the best treatment for each case.

Encapsulated acute subdural hematoma mimicking acute epidural hematoma on computed tomography.  

Science.gov (United States)

An 87-year-old woman presented with an atypical case of acute subdural hematoma (ASDH) manifesting as disturbance of consciousness and left hemiparesis. Computed tomography revealed a high density lentiform lesion in the right convexity, which was thought to be acute epidural hematoma preoperatively. Emergent decompressive craniotomy revealed an encapsulated solid fresh clot in the subdural space and a bleeding small cortical artery under the clot. The arachnoid membrane and the brain parenchyma were intact, and no other abnormal feature such as aneurysm or arteriovenous malformation was observed. The encapsulated ASDH was removed en bloc and the patient fully recovered. Histological examination confirmed that both the outer thicker and the inner membrane were fibrinous single structures without vasculature. The red blood cells constituting the clot in the capsule maintained their cell structure. The reported pathological mechanisms of lentiform ASDH are adhesion of the arachnoid membrane and the dura mater or intracapsular bleeding from sinusoidal vessels in the outer membrane of the chronic subdural hematoma. However, in our case, the arachnoid membrane had not adhered to the dura mater and the capsule was a fibrinous single structural membrane without vasculature, which probably resulted from a previous hematoma due to initial bleeding from the cortical artery. The possible mechanism in our case was that the re-bleeding dissected and flowed into the fibrinous single structural membrane, resulting in formation of the lentiform ASDH. PMID:23183078

Mouth-rinsing with chlorhexidine causes a delayed, temporary increase in the levels of oral viridans streptococci.  

Science.gov (United States)

The indigenous oral flora of 27 volunteers was monitored longitudinally over a 4-week period. Bacteria attached on buccal epithelial cells were counted by microscopy. Salivary bacterial colonies and the presence of alpha-hemolysis were examined after aerobic culturing on blood agar plates. The buccal and salivary bacterial counts were stably maintained in most subjects in the two repeated base-line samplings taken at 1-week intervals. Rinsing with a chlorhexidine mouthwash 45 min before sampling dramatically reduced the amount of epithelial cell-adherent bacteria. One day after the chlorhexidine rinse, however, the numbers of the epithelial cell-adherent bacteria exceeded the base-line level, and a similar decrease-increase pattern of changes was detected for the salivary alpha-hemolytic streptococcal counts. The non-hemolytic salivary bacterial counts were not affected by chlorhexidine. Subsequent weekly samplings showed no difference from the base-line samplings. The chlorhexidine-induced, delayed increase of viridans streptococci on oral epithelial surfaces should be considered a possible risk factor in medically compromised patients. PMID:7484104

Cervical spine intradural-extramedullary hematoma presenting as ipsilateral hemiparesis  

Directory of Open Access Journals (Sweden)

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

LEIOMYOSARCOMA PRESENTING AS A RECURRENT HEMATOMA OF THE DELTOID REGION  

Directory of Open Access Journals (Sweden)

Full Text Available Leiomyosarcoma is a rare cancer of smooth muscle. The prognosis depends on the patient's age and the size, histologic grade and stage of the tumor.CASE REPORT: The case of a 63year-old man diagnosed with a leiomyosarcoma of the deltoid region is reported. The patient was previously admitted twice in our surgical unit with a largerecurrent posttraumatic hematoma of the right deltoid region which was incised and drained. One month later the patient was readmitted under the suspicion of malignancy. Following the large excision of the lesion, pathology and immunohistochemistry report showed a poorly differentiated leiomyosarcoma. One year later the recurrency of the tumour in the upper arm and axillary region imposed a large excision of the tumour of the upper arm and the axillary tumour, followed by alatissimus dorsi miocutaneous flap reconstruction. 4 months later multiple pulmonary metastases were documented at chest X-ray and chemotherapy with doxorubicine was commenced. A new axillary recurrence occured 9 months later and was resected with clear margins followed by radiotherapy. In conclusion, the natural history and clinical picture of leiomyosarcoma may lead to diagnosis delay, poor local control of the disease with multiple recurrences and repeatedsurgery

Reversible acute anuric kidney injury after surgical evacuation of perinephric hematomas as a complication of renal transplant biopsies.  

Science.gov (United States)

Percutaneous renal transplant biopsy is the gold standard investigation to diagnose the cause of renal allograft dysfunction. There are inherent risks to this investigation, despite the procedure becoming safer due to the increased utilization of ultrasound-guided techniques. These biopsy risks can be increased when there is acute rejection present with a swollen transplanted kidney. Subcapsular hematomas are not uncommon after percutaneous renal transplant biopsies, but we describe two cases of post-biopsy subcapsular hematoma which were associated with acute renal allograft dysfunction in pediatric renal transplant recipients who did not have acute rejection.

Lifespan extension and delay of age-related functional decline caused by Rhodiola rosea depends on dietary macronutrient balance  

Science.gov (United States)

Background This study was conducted to evaluate the effects of rhizome powder from the herb Rhodiola rosea, a traditional Western Ukraine medicinal adaptogen, on lifespan and age-related physiological functions of the fruit fly Drosophila melanogaster. Results Flies fed food supplemented with 5.0 mg/ml and 10.0 mg/ml of R. rosea rhizome powder had a 14% to 17% higher median lifespan, whereas at 30.0 mg/ml lifespan was decreased by 9% to 12%. The preparation did not decrease fly fecundity. The effect of R. rosea supplement on lifespan was dependent on diet composition. Lifespan extension by 15% to 21% was observed only for diets with protein-to-carbohydrate ratios less than 1. Lifespan extension was also dependent on total concentration of macronutrients. Thus, for the diet with 15% yeast and 15% sucrose there was no lifespan extension, while for the diet with protein-to-carbohydrate ratio 20:1 R. rosea decreased lifespan by about 10%. Flies fed Rhodiola preparation were physically more active, less sensitive to the redox-cycling compound menadione and had a longer time of heat coma onset compared with controls. Positive effects of Rhodiola rhizome on stress resistance and locomotor activity were highest at the ‘middle age’. Conclusions The present data show that long-term food supplementation with R. rosea rhizome not only increases D. melanogaster lifespan, but also delays age-related decline of physical activity and increases stress resistance, what depends on protein-to-carbohydrate ratio of the diet.

Causes of developmental delay in children of 5 to 72 months old at the child neurology unit of Yaounde Gynaeco-Obstetric and Paediatric Hospital (Cameroon  

Directory of Open Access Journals (Sweden)

Full Text Available Background: According to the World Health Organization, about 5% of children world-wide of 14-year-old and under have a moderate to severe developmental disability, and up to 15% of children under 5-year-old are developmentally delayed. Purpose: To determine the prevalence, socio-demographic profile, aetiologies, and the clinical presentation of developmental delay in children less than 6-year-old at the child neurology unit in a university-affiliated hospital in Yaounde. Materials and methods: It was a crosssectional descriptive study carried out in Yaounde Gynaeco-Obstetric and Paediatric Hospital (Cameroon from August to December 2012. Children aged between 5 - 72 months with a developmental quotient less than 70 were enrolled. Developmental delay (DD was diagnosed and classified using the Denver developmental screening test (DDST. Data concerning the child (age, gender, severity of DD, the mother (age, age at conception, educational level, marital status, history of pregnancy and delivery, perinatal and postnatal events, results of para-clinical explorations (EEG, CT-scan, genetic tests, the severity of DD and the probable or demonstrate cause of DD were recorded on a standardized questionnaire. The chisquare test was used to compare variables. Results: During the study period, 2171 children aged 5 - 72 months consulted the paediatric department of the hospital, 296 were examined at the child neurology unit of which 153 had a developmental quotient less than 70, giving a hospital prevalence of 7.0% and a prevalence of 51.7% at the child neurology unit. The mean age was 26.6 ± 18.0 months and there were 56% males. The main reason for consulting was tonus disorder (43.8% and the developmental area of parental concern was the motor domain (90.2%. Regarding the clinical presentation, 75.2% of our population were children with cerebral palsy. DD was severe, mild, moderate and profound respectively in 14.2%, 13.5%, 12.2%, and 11.1%. Gross DD represented 90.2% of all DD children. The causes of DD were hypoxic-ischemic encephalopathy (41.8%, epilepsy (13.7%, sequelae of meningitis (6.5%, sequelae of kernicterus (6.5%, and infectious embryofoetopathies (5.2%. Conclusion: Developmental delay is frequent in paediatric neurology, with perinatal disorders being the leading aetiologies in Cameroon. Prevention of perinatal hypoxic-ischemic encephalopathy risk factors needs to be reinforced.

Chronic encapsulated intracerebral hematoma: Three case reports and a literature review  

Science.gov (United States)

Background: Chronic encapsulated intracerebral hematoma (CEIH) is one type of intracerebral hematoma that sometimes grows progressively while forming a capsule and presenting with neurological deficits. Although many cases of CEIH have been reported, correct preoperative diagnosis is very difficult. Only around 20% of cases are diagnosed preoperatively. Case Description: We encountered three cases of CEIH in which causes were unidentified and difficult to diagnose. All three cases were treated surgically. In the first case, a 59-year-old male was diagnosed preoperatively with metastatic brain tumor. In the second case, a 62-year-old female was diagnosed preoperatively with glioblastoma. The third case involved a 58-year-old female diagnosed preoperatively with CEIH. Conclusion: We should keep in mind that CEIH is a differential diagnosis for intracerebral space-occupying lesions. This report describes these three cases and discusses imaging findings and characteristics of CEIH. PMID:25024888

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

Directory of Open Access Journals (Sweden)

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.

[Hematoma of the abdominal wall. A case report: pitfall of Seldinger method via femoral artery].  

Science.gov (United States)

We reported a case of an abdominal wall hematoma which caused by Seldinger method via the femoral artery. A 48-year-old female, suffered from direct carotid cavernous fistula, was treated by transfemoral transvenous embolization (TVE). The whole procedure was completed without difficulty except minor resistance of guide wire manipulation during left femoral artery catheterization. Four hours later, the patient became hypotensive and showed the sign of impending shock without definitive causes. Nine hours after the embolization a huge hematoma of the abdominal wall was found. It required the total 1200 m/ of blood transfusion before her blood pressure returned to normal. She recovered fully from this event and discharged uneventfully. There is a speculation that a deep circumflex iliac artery (DCIA) was injured with an angle-shaped guide wire and bled into the abdominal wall. And subsequent systemic heparinization prevented the coagulation process, resulting a large hematoma. Anatomically, an angle-shaped guide wire is easily able to migrate into DCIA. To prevent a vascular injury, it is very important to manipulate a guide wire under fluoroscopic control and to select a J-shaped guide wire instead of an angle-shaped one. PMID:19227158

Biochemical, histopathological and clinical evaluation of delayed effects caused by methamidophos isoforms and TOCP in hens: ameliorative effects using control of calcium homeostasis.  

Science.gov (United States)

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

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)

Small amounts of venous gas embolism cause delayed impairment of endothelial function and increase polymorphonuclear neutrophil infiltration.  

Science.gov (United States)

Gas bubbles from decompression and gas embolization lead to endothelial dysfunction and mechanical injury in the pig, rabbit and lamb. In the study presented here, 0.01 ml air/min/kg was infused through a catheter into the jugular vein in 12 rabbits for 60 min. The endothelial response was measured using tension measurements in the blood vessel wall, and morphological changes where quantified using light microscopy and image processing. Percent lung water content was calculated and used to estimate the severity of pulmonary oedema. The infusion led to a significant decrease in the acetylcholine-mediated endothelial-dependent vasodilatation in the pulmonary artery 6 h after the infusion (6-h group, n = 6). A decrease in substance-P-mediated endothelial-dependent vasodilatation was also detected. No changes where seen in a group of rabbits examined 1 h after infusion (l-h group, n=6). The impaired endothelial-dependent vasodilatation caused by the bubbles is probably biochemical in origin, since no visible changes were seen in the endothelial layer. A significant increase in polymorphonuclear neutrophils was observed in the 6-h group compared to the l-h group. This study demonstrates that small numbers of bubbles, corresponding to "silent bubbles", lead to an impairment of the endothelial-dependent vasoactive response. PMID:11990728

Transient reflectivity response with negative time delay caused by femtosecond pulse propagation in GaAs thin films  

Energy Technology Data Exchange (ETDEWEB)

We have investigated the propagation effects on the transient response of confined excitons in GaAs thin films by a reflection-type pump-probe technique. The spectrally integrated signal demonstrated slower rise than the pulse width in the negative time region. Moreover, reflectivity change spectra indicate that the response in the negative time region originates from the effect of the confined excitons and that the signal rise time at each exciton state is different. The propagation velocities estimated from the rise times and the film thickness correspond to the group velocities of the exciton polariton in bulk crystals. Therefore, the origin of the responses in the negative time region is the pulse modulation caused by the propagation effect of exciton polariton. In addition, it was confirmed that this propagation disappears with an increase in temperature due to the spatial decoherence of excitons. These results demonstrate that the propagation effect of exciton polariton on optical response in femtosecond time scale has a considerable influence in the realization of ultrafast optical devices.

Epidural hematoma confirmed by contrast enhancement in computed tomography  

International Nuclear Information System (INIS)

Four cases of chronic epidural hematomas confirmed only by contrast enhancement are presented. In two cases, hematomas were found in the posterior fossa, in one, in both supra- and infratentorial regions, and in the remaining one, in the supratentorial region. Noncontrast CT failed to show the biconvex high-density area typical of an acute epidural hematoma. One supratentorial and two posterior fossa hematomas were definitely diagnosed only after an injection of the contrast medium. In the remaining one with combined supra- and infratentorial hematomas, a hematoma in the right occipital region was diagnosed on plain CT alone, but the left supratentorial lesion was confirmed only after the injection of an iodinated contrast medium. The mechanisms responsible for the enhancement of the margin of the chronic epidural hematoma are discussed. The dura mater in close contract with the inner table of the skull is usually not seen on the enhanced CT. The falx and tentorium are ordinarily well enhanced, however, and in patients who have undergone bone-flap removal, the dura mater without any juxtaposed skull is enhanced. It may be supposed that the enhanced margin as seen in chronic epidural hematoma represents either the enhanced dura mater displaced from the inner table of the skull, with or without overlying granulation tissue, or the compressed and congested brain underneath the hematoma, or both. An extravasation of the iodine from the immature neovasculature of the granum the immature neovasculature of the granulation tissue may prove to play an important role. The importance of the contrast enhancement in CT scanning of selected patients in chronic stage after the head injury is stressed. (author)

A case of anemia caused by combined vitamin B12 and iron deficiency manifesting as short stature and delayed puberty Anemia  

Directory of Open Access Journals (Sweden)

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.

MRI of spinal hematoma as a result of lumbar puncture  

International Nuclear Information System (INIS)

A 59-year-old woman was suspected of having meningitis. A lumbar puncture was performed for CSF analysis; however, a traumatic tap induced hemorrhage in the subarachnoid space and formed a hematoma from the L3 to the S1 level. This resulted in a paraparesis. Myelography showed a band-like filling defect and a subsequent computed tomography (CT) myelogram showed a soft tissue mass in the intradural space. T1 weighted magnetic resonance imaging revealed a lesion with moderate hyperintensity within the dural sac, hinting that the lesion was a hematoma. Laminectomy was performed, and the hematoma was entirely removed. (orig.)

A lumbar puncture was performed for CSF analysis; however, a traumatic tap induced hemorrhage in the subarachnoid space and formed a hematoma from the L3 to the S1 level. This resulted in a paraparesis. Myelography showed a band-like filling defect and a subsequent computed tomography (CT) myelogram showed a soft tissue mass in the intradural space. T1 weighted magnetic resonance imaging revealed a lesion with moderate hyperintensity within the dural sac, hinting that the lesion was a hematoma. Laminectomy was performed, and the hematoma was entirely removed. (orig.)

Intramural esophagic hematoma secondary to coumarinic anticoagulation: a case report.  

Science.gov (United States)

Esophagic Intramural Hematoma is an uncommon clinical condition, with a prognosis which is essentially benign. On most cases, a predisposing or precipitating factor may be seen, with the most common ones being the history of esophagic instrumentation, food impactations and thrombocytopenia. In the following manuscript, the authors present the case of a 54-years-old male with history of valve replacement surgery, who was treated at the Clinica Cardiovascular (Medellin, Colombia), with a clinical case of Intramural Esophagic Hematoma that was later confirmed to be due to a Coumarinic overanticoagulation. On this case, it is evidenced that Intramural Esophagic Hematoma is an unrecognized complication of Courmarinic anticoagulation therapy. PMID:20069068

Endoscopic burr hole evacuation of an acute subdural hematoma.  

Science.gov (United States)

Acute subdural hematoma evacuations frequently necessitate large craniotomies with extended operative times and high relative blood loss, which can lead to additional morbidity for the patient. While endoscopic minimally invasive approaches to chronic subdural collections have been successfully demonstrated, this technique has not previously been applied to acute subdural hematomas. The authors report their experience with an 87-year-old patient presenting with a large acute right-sided subdural hematoma successfully evacuated via an endoscopic minimally invasive technique. The operative approach is outlined, and the literature on endoscopic subdural collection evacuation reviewed. PMID:23962631

Spontaneously Developed Pulmonary Arterial Intramural Hematoma That Mimicked Thromboembolism  

Energy Technology Data Exchange (ETDEWEB)

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

The surgical management of chronic subdural hematoma.  

Science.gov (United States)

Chronic subdural hematoma (cSDH) is an increasingly common neurological disease process. Despite the wide prevalence of cSDH, there remains a lack of consensus regarding numerous aspects of its clinical management. We provide an overview of the epidemiology and pathophysiology of cSDH and discuss several controversial management issues, including the timing of post-operative resumption of anticoagulant medications, the effectiveness of anti-epileptic prophylaxis, protocols for mobilization following evacuation of cSDH, as well as the comparative effectiveness of the various techniques of surgical evacuation. A PubMed search was carried out through October 19, 2010 using the following keywords: "subdural hematoma", "craniotomy", "burr-hole", "management", "anticoagulation", "seizure prophylaxis", "antiplatelet", "mobilization", and "surgical evacuation", alone and in combination. Relevant articles were identified and back-referenced to yield additional papers. A meta-analysis was then performed comparing the efficacy and complications associated with the various methods of cSDH evacuation. There is general agreement that significant coagulopathy should be reversed expeditiously in patients presenting with cSDH. Although protocols for gradual resumption of anti-coagulation for prophylaxis of venous thrombosis may be derived from guidelines for other neurosurgical procedures, further prospective study is necessary to determine the optimal time to restart full-dose anti-coagulation in the setting of recently drained cSDH. There is also conflicting evidence to support seizure prophylaxis in patients with cSDH, although the existing literature supports prophylaxis in patients who are at a higher risk for seizures. The published data regarding surgical technique for cSDH supports primary twist drill craniostomy (TDC) drainage at the bedside for patients who are high-risk surgical candidates with non-septated cSDH and craniotomy as a first-line evacuation technique for cSDH with significant membranes. Larger prospective studies addressing these aspects of cSDH management are necessary to establish definitive recommendations. PMID:21909694

Extensive retroperitoneal hematoma in blunt trauma  

International Nuclear Information System (INIS)

To report our experience of managing extensive retroperitoneal hematoma (RH) in patients with blunt trauma and to determine any associated factors affecting causation and mortality. In this retrospective observational study, patients diagnosed with extensive RH following blunt trauma admitted to King Saud Medical Complex, Riyadh, Kingdom of Saudi Arabia between January 2004 and December 2009 were included. Patient data were explored for injury severity score (ISS), associated injuries, location of hematoma, amount of blood transfusions, coagulation profile, operative management, hospital stay, and mortality. The outcomes in surviving and non-surviving patients were compared. Out of 290 patients presenting with RH, extensive RH was found in 46 patients (15.8%). The overall mortality was 32.6%. The pelvis was the most frequent location of RH in combination with lateral and central zones (65.2%). The lower extremity and pelvic fractures were the most common injury. Associated intra-peritoneal injuries were present in 39.1% patients. An exploratory laparotomy was performed in 58.7% patients (n=27). A high ISS (55.9 versus 35.5, p<0.0001), abnormal coagulation profile (odds ratio [OR] 7.8, 95% confidence interval [CI] 1.974-30.932, p=0.005, and associated chest injuries OR 5.94, 95% CI 1.528-23.19, p=0.014) were independent factors associated with mortality. Multiple musculoskeletal injuries in addition to intra-abdominal injuries and abnormal coagulation are major factors associated with the presence of extensive RH. High ISS, abnormal coagulation, and associated chest injuries are independent factors associated with mortality (Author).

Los pacientes que necesitan intervenciones en varios niveles lumbares y/o que tienen una coagulopatía preoperatoria tienen un riesg [...] o significativamente mayor de desarrollar un hematoma epidural. La introducción de dosis altas de heparina de bajo peso molecular (HBPM), (30 mgrs. dos veces al día) aumentan la incidencia de hematomas neuroaxiales.

Nuestro paciente fue tratada con dosis altas de HBPM y desarrolló un déficit neurológico debido a un HEE, después de una punción lumbar. Fue operada al cabo de seis días y se recuperó parcialmente de su déficit después de la intervención. La administración actual de dosis altas de HBPM puede dar lugar a HEE, incluso después de una punción lumbar, que se hizo en pocos intentos.

Abstract in english Spinal epidural hematoma (SEH) is a known complication of spinal surgery, but the incidence of post-surgical SEHs that result in neurologic deficits is extremely rare (0.1%). Patients that require multilevel lumbar procedures and/or have a preoperative coagulopathy are at a significantly higher risk [...] of developing an epidural hematoma. The introduction of higher dose of low molecular weight heparin (LMWH) twice daily 30 mg regimen) increased the reported incidence of neuroaxial hematomas. 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.

Idiopathic intraparenchymal hematoma of the liver in a neonate  

Energy Technology Data Exchange (ETDEWEB)

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.)

A ligamentum flavum hematoma presenting as an L5 radiculopathy.  

Science.gov (United States)

This study reports two patients with ligamentum flavum hematoma, of which only seven cases have been reported in the literature. Two elderly male patients (74 and 80 years) presented with a history of chronic lumbar strain and effort. They had low back pain radiating to both legs. Their neurologic examination findings were consistent with left L5 root compression. Magnetic resonance imaging showed an epidural mass lesion at L4-L5 that was continuous with the ligamentum flavum. After removal of the hematoma, the symptoms completely resolved. The most common cystic lesion in the lumbar spine is synovial cyst associated with the facet joints, but ligamentum flavum hematoma should be included in the differential diagnosis. The clinical, radiological and surgical features are described. Surgery should be the treatment of choice to resolve symptoms in ligamentum flavum hematoma. PMID:17669655

Acute epidural hematoma complicating Paget's disease of the skull.  

Science.gov (United States)

Although among Anglo-Saxons Paget's disease is relatively common, it is very rare in Japan. The incidence of Paget's disease increases as age advances, and in elderly people over 90 years of age it can be seen in as many as 10%. On the other hand, acute epidural hematoma seldom occurs in the older generation, because dural adhesion to the internal table of the skull becomes more intense. We have encountered an 86-year old woman with advanced Paget's disease who developed an acute epidural hematoma after trivial head trauma. Acute epidural hematoma complicating Paget's disease has been reported only twice before and this case is the first report in Japan. The literature on the pathogenesis of the acute epidural hematoma complicating Paget's disease is reviewed. PMID:3941981

Spinal subarachnoid hematoma in a woman with HELLP syndrome: a case report  

Directory of Open Access Journals (Sweden)

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

Calf hematoma - computed tomographic and magnetic resonance findings  

International Nuclear Information System (INIS)

Four patients with hematomas of the calf are presented. The diagnosis was made by computed tomography (CT) in three cases and CT/magnetic resonance imaging (MRI) in one case. In all cases, CT or MRI clarified a confusing clinical picture. CT and MRI can help differentiate the types of calf mass (i.e., hematoma, tumor, Baker cyst, thrombophlebitis) and assist proper clinical management in a rapid, noninvasive fashion. (orig.)

Pathomechanism of ring enhancement in intracerebral hematomas on CT  

International Nuclear Information System (INIS)

As a simulation of hypertensive intracerebral hematoma, about 3.5 ml of autologus venous blood were injected into an artificial cavity of a unilateral cerebral hemisphere in dogs. The cavity was made by the insertion and inflation of a balloon canula near the basal ganglia region of the dog. At the acute stage after the injection, the hematoma showed a round-shaped and homogeneous high density. 9 days later, a positive ring enhancement appeared around this high-density area in most of the cases. Subsequently, the hematoma changed into an isodensity with a tendency toward the concentric concentration of the ring enhancement and to the final low-density stage with a spotted enhancement in the center. That is our experimental intracerebral hematoma of the dog showed a pattern of the chronological course of the CT appearance quite similar to that of clinical cases of hypertensive intracerebral hematomas. At the onset of the ring enhancement, many new and immature capillaries were noted in the adjacent tissue of the hematoma, corresponding to the positive enhancement. The new capillaries were gradually shifted to the center of the hematoma; the enhancement also coincided with them. The ultrastructures of these new capillaries were examined electronmicroscopically. There was some resemblance to the capillaries of muscle with many pinocytotic vesicles and shallowed tight junctions. These experimental facts suggest that the enhancement phenomenon occurred in close relationship to the newly produced hypervascularization of the capillaries around the hematoma, which was a phenomenon of the healing process of the lesion. Therefore, the pathomechanism of the enhancement was thought to be involved the pooling of the contrast media in the increased vascular bed as well as a loss of blood brain barrier in these newly produced immature capillaries.

CT picture charges in hematoma following hypertonic cerebral hemorrhage  

International Nuclear Information System (INIS)

The development of the hematoma and its regressive changes after hypertonic cerebral hemorrhage were studied in two patients receiving conservative treatment. As a modern diagnostic method, CT provides remarkable advantages in cases of intracranial bleeding by determining reliably the focus of hemorrhage. Moreover, CT helps to establish surgical indications, and since it is noninvasive, repeated CT examinations can be used for monitoring the fate of the intracerebral hematoma in cases where surgical intervention had not been indicated.

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.)

Defence responses regulated by jasmonate and delayed senescence caused by ethylene receptor mutation contribute to the tolerance of petunia to Botrytis cinerea.  

Science.gov (United States)

Ethylene and jasmonate (JA) have powerful effects when plants are challenged by pathogens. The inducible promoter-regulated expression of the Arabidopsis ethylene receptor mutant ethylene-insensitive1-1 (etr1-1) causes ethylene insensitivity in petunia. To investigate the molecular mechanisms involved in transgenic petunia responses to Botrytis cinerea related to the ethylene and JA pathways, etr1-1-expressing petunia plants were inoculated with Botrytis cinerea. The induced expression of etr1-1 by a chemical inducer dexamethasone resulted in retarded senescence and reduced disease symptoms on detached leaves and flowers or intact plants. The extent of decreased disease symptoms correlated positively with etr1-1 expression. The JA pathway, independent of the ethylene pathway, activated petunia ethylene response factor (PhERF) expression and consequent defence-related gene expression. These results demonstrate that ethylene induced by biotic stress influences senescence, and that JA in combination with delayed senescence by etr1-1 expression alters tolerance to pathogens.

Evaluation of intracerebral hematoma resorption dynamics with computed tomography  

International Nuclear Information System (INIS)

High mortality and severe grade of disability observed in patients after intracerebral hemorrhage provide efforts to improve diagnostics and therapy of the hemorrhagic cerebral stroke. An aim of this paper was an evaluation of blood resorption dynamics in patients with intracerebral hematoma, performed with computed tomography of the head and an analysis of clinical significance of this process. An examined group included 133 patients with intracerebral hematoma proven by a CT exam. In 97 patients resorption of the hematoma was measured, based on control scans taken on 15th and 30th day on average. Volume of the hemorrhagic foci was measured as well as the width of ventricles and the displacement of medial structures. The mean hematoma volume reached 11,59 ml after 15 days, and 3,16 m after 30 days (average decrease of the volume 0,67 ml/day). There was a significant difference in the rate of resorption between the first (0-15 days) and the second (15-30 days) observation period - 0,78 and 0,62 ml/day respectively. The dynamics of the process was dependent on volume and localization of the hematoma and independent of the grade of displacement and compression of the ventricles. The calculated mean rate of the hematomas resorption enables to schedule control examinations precisely. The significant differences of the dynamics of blood resorption depending on hematomas size and the independence of compression and displacement of ventricular system su and displacement of ventricular system suggest, that the most important factor in therapeutic decision-making should be a clinical status of the patient.

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  

Science.gov (United States)

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.

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

Directory of Open Access Journals (Sweden)

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

Chronic subdural hematoma secondary to traumatic subdural hygroma  

International Nuclear Information System (INIS)

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

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

Cerebral atrophy and crossed cerebellar atrophy following acute subdural hematoma in infant  

International Nuclear Information System (INIS)

Crossed cerebellar atrophy (CCA) on imaging study reflects secondary degeneration of the cerebellar hemisphere caused by neuronal disconnection with the contralateral cerebral hemisphere. We report an 11-month-old child with traumatic left acute subdural hematoma, who showed crossed cerebellar atrophy on MR images. Eighteen months after the trauma, MR images showed brain atrophy not only in the left cerebral hemisphere but also in the right cerebellar hemisphere. The cerebellar atrophy was prominent in the lateral part. This finding is consistent with CCA and may support neuronal interactions between the cerebral hemisphere and the lateral part of the contralateral cerebellar hemisphere. (author)

Spontaneous sternocleidomastoid muscle hematoma following thrombolysis for acute ischemic stroke.  

Science.gov (United States)

Spontaneous or traumatic bleeding is a common complication of systemic thrombolysis in patients with acute ischemic stroke. We report the case of an 83 y.o. woman with right facio-brachio-crural hemiparesis, left deviation of the head and aphasia who developed, after thrombolytic therapy, a spontaneous sternocleidomastoid muscle hematoma that regressed few days later. To our knowledge, this is the first case reported in the literature of asymptomatic and spontaneous skeletal muscle hematoma following thrombolysis for the treatment of acute ischemic stroke. The occurrence of lateral cervical tuberculosis lymphadenitis ipsilateral to sternocleidomastoid muscle hematoma may suggest a causal relationship between local chronic inflammation of active mycobacterial infection and thrombolysis-related extravasation. This case should suggest caution in thrombolytic treatment in patients with chronic immune dysregulation and vascular inflammation such as extra-pulmonary tuberculosis. PMID:24774751

Calcified Splenic Hematoma Presenting as a Pelvic Mass  

Directory of Open Access Journals (Sweden)

Full Text Available The spleen is the most vulnerable visceral organ involved in blunt abdominal trauma;40% to 70% of patients with blunt splenic laceration can be managed with nonsurgicalmethods. A majority of hematomas of the spleen can heal and be absorbed within 2 to 3months; through an unknown mechanism in an unusual condition, the hematoma mayorganize and eventually calcify. Herein, we report on a senile female with blunt abdominaltrauma 6 years previous, who turned out to have a calcified splenic hematoma with clinicalpresentations of a palpable pelvic mass and intestinal obstruction. A total splenectomy,including the calcified mass, was performed. She experienced great clinical improvementpostoperatively. She was uneventfully discharged 1 week later

Supratentorial arachnoid cyst and associated subdural hematoma: neuroradiologic studies  

Energy Technology Data Exchange (ETDEWEB)

CT and MR images of 8 patients with supratentorial arachnoid cyst complicated by subdural hematoma were studied and compared with those of 8 patients who developed nontraumatic subdural hematoma without arachnoid cyst. Ot the 8 patients with supratentorial arachnoid cyst, CT and MR disclosed temporal bulging and/or thinning of the temporal squama in all 6 patients with middle fossa arachnoid cysts, and the thinning of the calvaria was evident in another patient with a convexity cyst. Calvarial thinning at the site corresponding to interhemispheric arachnoid cyst was clearly depicted on coronal MR images. In contrast, none of the 8 young patients with nontraumatic subdural hematoma without arachnoid cyst had abnormal calvaria. Temporal bulging and thinning of the overlying calvaria were identified as diagnostic CT and MR features of arachnoid cyst with complicating intracystic and subdural hermorrhage.

Supratentorial arachnoid cyst and associated subdural hematoma: neuroradiologic studies  

International Nuclear Information System (INIS)

CT and MR images of 8 patients with supratentorial arachnoid cyst complicated by subdural hematoma were studied and compared with those of 8 patients who developed nontraumatic subdural hematoma without arachnoid cyst. Ot the 8 patients with supratentorial arachnoid cyst, CT and MR disclosed temporal bulging and/or thinning of the temporal squama in all 6 patients with middle fossa arachnoid cysts, and the thinning of the calvaria was evident in another patient with a convexity cyst. Calvarial thinning at the site corresponding to interhemispheric arachnoid cyst was clearly depicted on coronal MR images. In contrast, none of the 8 young patients with nontraumatic subdural hematoma without arachnoid cyst had abnormal calvaria. Temporal bulging and thinning of the overlying calvaria were identified as diagnostic CT and MR features of arachnoid cyst with complicating intracystic and subdural hermorrhage. Radiologists should be aware of this association and should evaluate the bony structure carefully. (orig.)

Hematoma subdural crónico calcificado. Reporte de un caso  

Directory of Open Access Journals (Sweden)

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.

Intracranial Rhabdomyosarcoma Presented as Chronic Subdural Hematoma: A Case Report  

Directory of Open Access Journals (Sweden)

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

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

Multiple remote epidural hematomas following pineal gland tumor resection  

Directory of Open Access Journals (Sweden)

Full Text Available In cases of pineal tumor combined with obstructive hydrocephalus, preoperative ventriculostomy or ventriculoperitoneal shunting is typically required prior to tumor resection. The objectives of preoperative ventriculostomy are gradual reduction of intracranial pressure and consequent preoperative brain protection. Here we report a case of pineal tumor resection with preoperative ventriculostomy that was complicated by multiple epidural hematomas. While postoperative intracranial hemorrhage may occur at any site, it is rare in those areas remote from the operative field. In the present case, multiple remote sequential epidural hematomas developed following resection of a pineal gland tumor. We also discuss the pathophysiologic mechanisms and provide a literature review.

Prediction and Observation of Post-Admission Hematoma Expansion in Patients with Intracerebral Hemorrhage  

Science.gov (United States)

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.

Hematoma subaracnoideo espinal tras punción lumbar en paciente con leucemia: Presentación de un caso y revisión de la literatura / Spinal subarachnoid hematoma after lumbar puncture in a patient with leukemia: Report of a case and review of the literature  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish La compresión mielo-radicular aguda secundaria a un hematoma subaracnoideo espinal (HSAE) es una complicación extremadamente rara tras una punción lumbar (PL). En el mecanismo de producción de estos hematomas han sido implicados diversos factores de riesgo, principalmente la presencia de trastornos [...] de la hemostasia en el paciente. Presentamos el caso de un varón de 20 años con leucemia aguda y trombocitopenia (26.000 plaquetas/mm³) que, tras ser sometido a una PL, desarrolló una paraparesia con imposibilidad para la bipedestación. La resonancia magnética (RM) demostró la presencia de un hematoma intradural ventral desde D12 hasta L4. Se realizó una laminectomía descompresiva de urgencia y se pudo evacuar parcialmente un hematoma localizado en el espacio subaracnoideo. Al cuarto día postoperatorio, el paciente consiguió caminar sin ayuda, pero falleció un mes después debido a complicaciones sistémicas de su enfermedad. Sólo se han encontrado 26 casos de HSAE tras PL en la revisión de la literatura que hemos realizado. Se han observado las siguientes características comunes a la mayoría de ellos: asociación con tratamientos anticoagulantes, asociación con trombocitopenia, aparición de síndrome compresivo mielo-radicular de forma retardada, necesidad de tratamiento quirúrgico, buen resultado funcional en la mitad de los pacientes, y corta esperanza de vida en aquellos con enfermedad previa grave. En pacientes leucémicos con tendencia a tener marcada trombocitopenia (quizás por debajo de 25.000 plaquetas/mm³), el riesgo de desarrollar un HSAE tras PL puede ser elevado. Abstract in english Acute myeloradicular compression due to a spinal subarachnoid hematoma (SSAH) after lumbar puncture (LP) is an extremely rare complication. Several risk factors have been involved in the production of these hematomas, mainly the presence of hemostasis disorders in the patient. We report the case of [...] a 20-year-old man with leukemia and thrombocytopenia (26,000 platelets/mm³) who, after undergoing a LP, developed paraparesis and became unable to stand. A magnetic resonance disclosed the presence of a ventral intradural hematoma from D12 to L4. An emergency decompressive laminectomy was performed and an hematoma located in the subarachnoid space was partially removed. On the fourth postoperative day, the patient was able to walk without assistance, but one month later, he died because of systemic complications of his disease. Only 26 cases of SSAH after LP have been found in the literature review we have performed. In most of them, the following common features have been observed: association with anticoagulant therapies, association with thrombocytopenia, delayed onset of compressive myeloradicular syndrome, need of surgical treatment, good functional outcome in half of patients, and short life expectancy for patients with previous serious illness. Risk for developing a SSAH after LP could be high in leukemia patients with a tendency to have severe thrombocytopenia (perhaps less than 25,000 platelets/mm³).

Acute posterior fossa epidural hematoma in a newborn infant with Menkes disease.  

Science.gov (United States)

Epidural hematoma (EDH) in newborn infants is rare compared with other types of intracranial hemorrhages. Furthermore, posterior fossa EDH is extremely rare. We present a case of posterior fossa EDH in an infant with Menkes disease with accessory bones in the occiput. A male infant with a condition diagnosed with Menkes disease by prenatal testing was born at 39 weeks via vacuum extraction. The patient presented with a mild tremor at 2 days after delivery. A brain computed tomography (CT) scan showed an acute EDH in the posterior fossa, extending into the occipitoparietal area. Three-dimensional CT and bone window CT scan revealed several accessory bones, diastasis of 1 accessory suture, a communicated fracture, and a linear fracture in the occipital bone. Furthermore, a bone fragment from a communicated fracture displaced toward the inside. The patient was treated conservatively for EDH because of his good general condition. The hematoma gradually resolved, and his tremor did not recur. We suggest the following mechanism of posterior fossa EDH development in our patient: (1) external force was applied to the occiput inside the birth canal during delivery, resulting in diastasis; (2) a communicated fracture occurred, and a bone fragment displaced toward the inside (linear fracture was caused indirectly by the force); (3) a transverse sinus was injured by the fragment; and (4) EDH developed in both the posterior fossa and supratentorial region. Copper deficiency can also cause fragility of connective tissues, vessels, and bones. PMID:24488163

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

International Nuclear Information System (INIS)

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

Neuropathologic analysis of hematomas evacuated from patients with spontaneous intracerebral hemorrhage.  

Science.gov (United States)

Spontaneous intracerebral hemorrhage (ICH) is a devastating cause of morbidity and mortality. Intraparenchymal hematomas are often surgically evacuated. This generates fragments of perihematoma brain tissue that may elucidate their etiology. The goal of this study is to analyze the value of these specimens in providing a possible etiology for spontaneous ICH as well as the utility of using immunohistochemical markers to identify amyloid angiopathy. Surgically resected hematomas from 20 individuals with spontaneous ICH were examined with light microscopy. Hemorrhage locations included 11 lobar and nine basal ganglia hemorrhages. A? immunohistochemistry and Congo red stains were used to confirm the presence of amyloid angiopathy, when this was suspected. Evidence of cerebral amyloid angiopathy (CAA) was observed in eight of the 20 specimens, each of which came from lobar locations. Immunohistochemistry confirmed CAA in the brain fragments from these eight individuals. Patients with immunohistochemically confirmed CAA were older than patients without CAA, and more likely to have lobar hemorrhages (OR 3.0 and 3.7, respectively). Evidence of CAA was not found in any of the basal ganglia specimens. One specimen showed evidence of CAA-associated angiitis, with formation of a microaneurysm in an inflamed segment of a CAA-affected arteriole, surrounded by acute hemorrhage. In another specimen, A? immunohistochemistry showed the presence of senile plaques suggesting concomitant Alzheimer's disease (AD) changes. Surgically evacuated hematomas from patients with spontaneous ICH should be carefully examined, paying special attention to any fragments of included brain parenchyma. These fragments can provide evidence of the etiology of the hemorrhage. Markers such as A? 1-40 can help to identify underlying CAA, and should be utilized when microangiopathy is suspected. Given the association of (A?) CAA with AD, careful examination of entrapped brain fragments may also provide evidence of AD in a given patient. PMID:24354628

Spontaneous Cervico-Thoracic Spinal Epidural Hematoma in an Elderly Patient: A Rare Presentation  

Directory of Open Access Journals (Sweden)

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

Magnetic resonance imaging of hematomas in a 0.02 T magnetic field  

International Nuclear Information System (INIS)

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

Intracerebral low-density areas following acute epidural hematomas  

International Nuclear Information System (INIS)

The author studied secondary lesion after head injury; they could be distinguished from the primary lesions by computerized tomography (CT). Subjects were limited to patients with unilateral supratentorial epidural hematomas, all of whom had been operated on in the Ashikaga Red Cross Hospital. These patients were classified into two groups based on the intermittent serial CT findings; with (13 cases, Group I) and without (17 cases, Group II) intracerebral low-density areas. In the preoperative stage, Group I was severer on the level of conciousness and showed a greater volume of the epidural hematoma on CT than did Group II. The patient's age or sex, or the preoperative administration of mannitol and glycerol did not significantly affect the appearance of the intracerebral low-density areas on CT. In both groups, intradural findings were variable during the operation, but these findings could not be distinguished well between groups. As compared with Group II, Group I had worse outcomes. Neurological deficits, such as hemiparesis, mental disorders, visual disturbance, and epileptic seizures, remained for years. The low-density areas appeared in the cerebrum just below the hematomas (9 cases) in the territory of the posterior cerebral artery (4 cases), and in the boundary zone between anterior, middle and/or posterior cerebral arteries (3 cases). The low-density areas appeared mostly within 24 hours after head injury, while the findings of an abnormal contrast enhancem findings of an abnormal contrast enhancement in the low-density areas were often demonstrated during one to six weeks after injury. These findings resembled those of the cerebral ischemic lesions or infarction, not those of the cerebral contusion on CT. The conclusion of the study is that the appearance of the intracerebral low-density areas on CT following the evacuation of acute epidural hematomas marks a cerebral ischemic secondary lesion occurring as a result of the compression of the hematomas.

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. Abstract in spanish 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). Es un episodio agudo y el tratamiento tradicionalmente aplicado es la descompresión quirúrgica de urg [...] encia. Recientemente, en casos específicos, el tratamiento con corticosteroide ha sido aplicado como alternativa y con una buena recuperación neurológica. El objetivo de este relato fue exponer un caso de hematoma peridural con tratamiento conservador y recuperación neurológica completa. RELATO DEL CASO: Paciente del sexo femenino, 34 años, estado físico ASA I, sin ningún historial de coagulopatía o terapia anticoagulante, sometida a la anestesia peridural con punción única, en L2-L3, para tratamiento quirúrgico de várices en los miembros inferiores. Ocho horas después de la anestesia regional, todavía presentaba bloqueo motor completo (escala de Bromage), reducción de las sensibilidades térmica y dolorosa por debajo del nivel L3, hiperalgesia en la región plantar izquierda, preservación de los reflejos tendinosos y ausencia de dolor lumbar. La tomografía computadorizada reveló hematoma peridural en L2 con compresión del saco dural. Diez horas después de la punción peridural no había progresión de las señales y síntomas neurológicos. Se optó entonces por el tratamiento con metilprednisolona en infusión venosa continua (5,3 mg.kg-1 en la primera hora y 1,4 mg.kg-1.h-1 en las 23 horas siguientes). Ocho horas después del inicio del tratamiento, la paciente r

Spinal anterior epidural hematoma in an elderly man with unrecognized lupic anticoagulant taking warfarin.  

Science.gov (United States)

Spinal epidural hematoma (SEH) is a rare acute condition defined as a hematoma occurring at spinal epidural level. It is defined as "spontaneous" (SSEH) when possible causes have been ruled out; in other cases, clotting disorders and systemic lupus erythematosus have been associated with SEH. If identified rapidly, SEH can be completely cured, with complete recovery in about 50% of cases. We describe the case of an 86-year-old man affected by SEH, with rare anterior location, presenting with painful paraparesis and bladder dysfunction. The patient was taking warfarin for chronic atrial fibrillation. A prolongation of partial thromboplastin time was observed, consistent with the presence, in plasma, of previously unrecognized lupus anticoagulant antibodies (LA). The diagnosis of SEH was confirmed by MRI, and the patient was not surgically treated. Following a rehabilitation program, the patient had complete neurological recovery. Although the epidural lesion might have been a true case of SSEH, anticoagulation therapy and AL may have played a role in the pathogenesis, spread and spontaneous resolution of SEH. In cases of acute thoracic pain, associated with signs and symptoms of spinal cord compression, the diagnosis of SEH, which is a potentially devastating condition, must be carefully investigated by clinicians.

Spontaneous iliopsoas muscle hematoma in a patient with von Willebrand disease: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Iliopsoas hemorrhage is a serious complication of bleeding disorders that occurs most commonly in patients with hemophilia and less commonly in patients with von Willebrand disease. It causes severe pain, muscle dysfunction and occasionally femoral nerve palsy. We describe the case of a patient with von Willebrand disease type 3 with a large iliopsoas hematoma who was treated with a von Willebrand factor concentrate (Humate-P. Case presentation A 20-year-old Iranian man was referred to our emergency ward because of the gradual onset of right flank pain. He was known to have been diagnosed with von Willebrand disease type 3 at age two years old. Magnetic resonance imaging showed a mass in the right iliopsoas muscle. The diagnosis of iliopsoas hemorrhage and partial femoral nerve palsy was established, and he responded to medical treatment. Conclusion We report a case of von Willebrand disease type 3 with spontaneous iliopsoas hematoma associated with femoral nerve palsy that was well managed with Humate-P treatment.

[Three cases of acute subdural hematoma in abused children].  

Science.gov (United States)

We encountered 3 cases of battered children with acute subdural hematoma. In this report, we discuss the difficulties in treating this condition surgically, and we emphasize the importance of early diagnosis and treatment of abused children and their parents. Case 1: A girl, aged 2 months, was brought in by her mother, because the child had become drowsy. The mother stated that the child had been battered by her father. Physical examination revealed tense anterior fontanelle, bruises on her face, consciousness disturbance and retinal bleeding. Marked anemia was revealed on laboratory studies. A computed tomographic (CT) scan demonstrated an interhemispheric subdural hematoma in the parietooccipital region. She was treated conservatively for 2 months. Follow-up CT revealed a bilateral chronic subdural hematoma. Burr hole irrigation and drainage on both sides brought about complete disappearance of these lesions. Case 2: A girl, aged 1 year and 9 months, was brought in by her parents. According to her mother's allegation, the child fell down from the top of an indoor slide and became comatose. Physical examination revealed severe malnutrition, loss of consciousness, dilated pupils and negative light reflex. Numerous areas of subcutaneous bleeding and skin erosions were seen on her back and abdomen. Marked anemia was revealed on laboratory studies. CT scan demonstrated a left acute subdural hematoma and massive brain swelling. Despite an emergency craniotomy, the child died 5 days later. Case 3: A 4-year-old boy was admitted in a comatose state. According to his mother's allegation, he was thrown to the floor from a 1.5m height and struck against a wall by his father. Physical examination revealed severe malnutrition, consciousness loss, dilated pupils and negative light reflex. Many scratches and bruises were seen over his whole body, especially on his back. Marked anemia was revealed on laboratory studies. A CT scan demonstrated a left acute subdural hematoma and massive brain swelling. Three days later, he died despite emergency craniotomy. The incidence of battered children is increasing in Japan, and these cases sometimes involve severe head injuries, such as subdural hematoma. In these cases, successful surgical treatment is difficult after admission to the neurosurgical institute. This may result from late admission as well as marked anemia and malnutrition. Therefore, we conclude that early diagnosis of child abuse and treatment of the abused child and psychological treatment for their parents are very important. PMID:8914155

Risk factors for post-traumatic massive cerebral infarction secondary to space-occupying epidural hematoma.  

Science.gov (United States)

Post-traumatic massive cerebral infarction (MCI) is a fatal complication of concurrent epidural hematoma (EDH) and brain herniation that commonly requires an aggressive decompressive craniectomy. The risk factors and surgical indications of MCI have not been fully elucidated. In this retrospective study, post-traumatic MCI was diagnosed in 32 of 176 patients. The performance of a decompressive craniectomy simultaneously with the initial hematoma-evacuation surgery improved their functional outcomes, compared with delayed surgery (on the 6-month Extended Glasgow Outcome Scale, 5.6±1.5 vs. 3.4±0.6; pmydriasis (OR, 7.08; p=0.004), preoperative brain herniation for longer than 90?min (OR, 6.41; p<0.001), and a Glasgow Coma Score of 3-5 points (OR, 2.86; p<0.053). Multi-variate logistic regression analysis revealed no significant association between post-traumatic MCI and age, gender, mid-line shift, Rotterdam computed tomography score, intraoperative hypotension, or serum concentrations of sodium or glucose. Incidence of post-traumatic MCI increased from 16.4% in those having any two of the six risk factors to 47.7% in those having any three or more of the six risk factors (p<0.001). Patients with concurrent EDH and brain herniation exhibited an increased risk for post-traumatic MCI with the accumulation of several critical clinical factors. Early decompressive craniectomy based on accurate risk estimation is recommended in efforts to improve patient functional outcomes. PMID:24773559

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.

CT of blunt renal injury; correlation of renal injury and retroperitoneal hematoma  

Energy Technology Data Exchange (ETDEWEB)

The this study was performed to evaluate whether the extent and location of retroperitoneal hematoma correlate with the severity of renal injury. We evaluated the CT findings of 27 patients with renal trauma. The retroperitoneal hematoma were subdivided into perirenal hematoma(PRH), anterior pararenal hematoma(APH), posterior parareneal hematoma(PPH) and interfascial hematoma(IFH). The perirenal hematoma(PRH) was classified as grade I, II and III according to the amount of hematoma. PRH was present in all 27, PPH in 8, IFH in 3 patients and APH was not observed. Grade I PRH was present in 7 (70%) of 10 minor injury (contusion, intrarenal hematoma), grade III PRH in2(20%) of 10 minor injury and in 7 (41.2%) of 17 major and catastrophic injury (laceration, fracture, shattered kidney and renal pedicle injury). Eight PPH were present only in the major and catastrophic injury and 3 IFH in each of intrarenal hematoma, laceraton and pedicle injury. The location and extent of PRH and PPH correlated somewhat with the severity of renal injury, while the presence of IFH and APH did not correlate with severity of the renal injury.

Delayed fission  

Energy Technology Data Exchange (ETDEWEB)

Delayed fission is a nuclear decay process that couples {beta} decay and fission. In the delayed fission process, a parent nucleus undergoes {beta} decay and thereby populates excited states in the daughter. If these states are of energies comparable to or greater than the fission barrier of the daughter, then fission may compete with other decay modes of the excited states in the daughter. In this paper, mechanism and some experiments of the delayed fission will be discussed. (author)

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

Directory of Open Access Journals (Sweden)

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.

Trombo aortico intraluminal e hematoma intramural apos manobra de ressuscitacao cardiopulmonar / Aortic luminal thrombus and intramural hematoma after cardiopulmonary resuscitation  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Descrevemos o caso de um paciente com hematoma intramural e trombo flutuante após ressuscitação cardiopulmonar. Esse homem, de 92 anos de idade, teve uma parada cardíaca causada por fibrilação atrial e testemunhas iniciaram imediatamente manobras manuais de ressuscitação cardiopulmonar. 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.

Cervical spinal epidural hematoma following cervical posterior laminoforaminotomy.  

Science.gov (United States)

A 65-year-old man who had lateral cervical disc herniation underwent cervical posterior laminoforaminotomy at C5-6 and C6-7 level right side. During the operation, there was no serious surgical bleeding event. After operation, he complained persistent right shoulder pain and neck pain. Repeated magnetic resonance image (MRI) showed diffuse cervical epidural hematoma (EDH) extending from C5 to T1 level right side and spinal cord compression at C5-6-7 level. He underwent exploration. There was active bleeding at muscular layer. Muscular active bleeding was controlled and intramuscular hematoma was removed. The patient's symptom was reduced after second operation. Symptomatic postoperative spinal EDH requiring reoperation is rare. Meticulous bleeding control is important before wound closure. In addition, if patient presents persistent or aggravated pain after operation, rapid evaluation using MRI and second look operation is needed as soon as possible. PMID:23560180

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

[Epidural hematoma following epidural catheter anesthesia in thrombocytopenia].  

Science.gov (United States)

We report a 21-year-old male patient suffering from acute myeloid leukemia and concomitant thrombocytopenia. Following a diagnostic thoracotomy-which revealed Aspergillus pneumonia-he developed respiratory insufficiency and dyspnea. A thoracic epidural catheter was inserted and epidural morphine treatment led to improved ventilation. No clinical signs of pathological epidural processes were noticed during the treatment. The patient died of Aspergillus sepsis 26 days after catheter insertion. Autopsy revealed bacterial growth in the epidural space with slight infectious tissue reactions as well as an epidural hematoma. No evidence of spinal cord compression was found at autopsy. The development of epidural infection or hematoma seems to be a possible complication of epidural analgesia in patients suffering from impaired defense mechanisms or thrombocytopenia. These risk factors should be taken into account when epidural analgesia is considered. We suggest that the platelet count should be determined beforehand in patients suspected of having thrombocytopenia (e.g. cancer, pre-eclampsia). PMID:3353526

Diplopia from Subacute Bilateral Subdural Hematoma after Spinal Anesthesia  

Directory of Open Access Journals (Sweden)

Full Text Available Subdural hematoma (SDH is a rare, but life-threatening complication of spinal anesthesia. Subdural hematoma resulting from this procedure could present with vague symptoms such as chronic headache and could easily be missed. Chronic headache is one of the symptoms of chronic SDH in postpartum women. Diplopia as the presenting complaint in SDH secondary to peripartum spinal anesthesia has not, to our knowledge, been previously reported. Here, we report a case of diplopia secondary to postpartum subacute bilateral SDHs with transtentorial herniation after spinal anesthesia in a healthy primagravid 25-year-old woman. SDH can expand gradually and the initial symptoms might be subtle as in our case, despite critically high intracranial pressure. [West J Emerg Med. 2012;13(1:108–110.
