Car sunshade-induced craniofacial injury: a case report
<p>Abstract</p> <p>Introduction</p> <p>We report the case of a man who sustained a craniofacial injury after spontaneous lateral airbag deployment resulting in his face being struck by a car sunshade. This highlights the potential damage that can be caused by any object placed between a lateral airbag and a car occupant.</p> <p>Case presentation</p> <p>We report the case of a 33-year-old Caucasian man who was the driver in a frontal collision. He had opened the car sunshade and turned it 90° towards the left. As he was driving, he struck a bus, causing the driver's lateral airbag to spontaneously deploy. The airbag pushed the sunshade against his face and injured him.</p> <p>Conclusions</p> <p>Car sunshades can cause significant craniofacial injury. We suggest that sunshade design must be improved to reduce the risk of potential injuries to car occupants. We recommend a new, safer sunshade design.</p
Intraoperative Ultrasonography in Resection of Diffuse Glioma
Diffuse glioma is a primary brain tumor that originates from glial supportive cells and is the most common type of intra-axial brain tumor. Open tumor resection is the first step in the treatment of diffuse gliomas. The extent of resection (EOR) directly influences clinical outcomes in glioma surgery. However, resection of diffuse glioma is encountered with the problem of macroscopic and even microscopic similarity of normal brain and tumor. Furthermore, maximizing EOR requires attention because a mistake in identifying and preserving normal brain regions in complete resection can lead to catastrophic complications
Value of ABCD2 in Predicting Early Ischemic Stroke in Patients Diagnosed with Transient Ischemic Attack
As a significant number of patients diagnosed with transient ischemic attack (TIA) at emergency department are at risk to develop TIA or cerebral vascular accident (CVA), several attempts have been made to figure out a predictive method to detect those at higher risk of such attacks. We aimed to evaluate the role of ABCD2 scoring which includes age, blood pressure, clinical symptoms, diabetes mellitus, and duration of symptoms in predicting short term outcome of the patients presenting with TIA. One hundred consecutive patients visited between 2009 and 2010 in Hazrat Rasoul Akram Hospital and diagnosed with TIA were enrolled and their ABCD2 scores were registered. The incidence of death, CVA, or TIA during the first week after the attack was recorded. Eleven patients suffered new TIA/CVA after 1 week. Sensitivity and specificity of ABCD2 score for predicting CVA/TIA at cut-off point of 4 were 72.7% and 52.8%, respectively. At the same cut-off point for ABCD2, positive and negative predictive values were 16% and 94 %, respectively. Our results show that although patients with ABCD2 score greater than 4 were more likely to develop recurrent TIA/CVA in short term, those with lesser score still harbour a considerable risk for TIA/CVA. Though ABCD2 as an easily applicable tool is very helpful in management of TIA patients at emergency department, but it should not be the only measure to rely on in our decision making
Value of ABCD2-F in Predicting Cerebral Ischemic Attacks: Three Months Follow-Up after the Primary Attack
Cerebrovascular attack (CVA) and transient ischemic attack (TIA) are major causes of emergency department visits around the globe. A significant number of these patients may experience repeat attacks if left untreated. Several risk stratifying scoring systems have been developed in recent years to point out the high risk patients. ABCD2 is based on age, blood pressure, clinical status, diabetes mellitus, and duration of symptoms and is used commonly for this purpose. In this study, we were to enhance its sensitivity and specificity with the addition of another criterion namely atrial fibrillation and making ABCD2-F. A prospective study in two hospitals was performed and 138 patients diagnosed with TIA/CVA were enrolled. Demographic, clinical, and paraclinical data of all patients were registered. All patients were followed for three months for any sign or symptom of a recurrent ischemic attack. Recurrent ischemic attacks happened in 9.4% of the patients. None of the criteria of ABCD2-F was associated with higher chance of ischemic attacks. Similarly, ABCD2-F was not different between patients with or without repeat cerebral ischemia. The addition of atrial fibrillation to ABCD2 did not enhance the accuracy of this scoring system to detect patients high risk for repeat cerebral ischemia. More studies in the future to improve sensitivity and specificity of this test are warranted
Accuracy of chest radiography versus chest computed tomography in hemodynamically stable patients with blunt chest trauma
【Abstract】 Objective: Thoracic injuries are respon-
sible for 25% of deaths of blunt traumas. Chest X-ray (CXR)
is the first diagnostic method in patients with blunt trauma.
The aim of this study was to detect the accuracy of CXR
versus chest computed tomograpgy (CT) in hemodynami-
cally stable patients with blunt chest trauma.
Methods: Study was conducted at the emergency
department of Sina Hospital from March 2011 to March 2012.
Hemodynamically stable patients with at least 16 years of
age who had blunt chest trauma were included. All patients
underwent the same diagnostic protocol which consisted
of physical examination, CXR and CT scan respectively.
Results: Two hundreds patients (84% male and 16%
female) were included with a mean age of (37.9±13.7) years.

Rib fracture was the most common finding of CXR (12.5%)
and CT scan (25.5%). The sensitivity of CXR for hemothorax,
thoracolumbar vertebra fractures and rib fractures were 20%,
49% and 49%, respectively. Pneumothorax, foreign body,
emphysema, pulmonary contusion, liver hematoma and ster-
num fracture were not diagnosed with CXR alone.
Conclusion: Applying CT scan as the first-line diag-
nostic modality in hemodynamically stable patients with
blunt chest trauma can detect pathologies which may change
management and outcome.

Principles of Primary Survey and Resuscitation in Cases of Pediatric Trauma
Trauma is a common cause of death and disability in children. Proper approach to pediatric trauma involves adherence to ABCDE sequence in the primary survey and resuscitation in order to promptly recognize and manage life-threatening conditions immediately. This readily reviewed sequence includes A: establishment and maintenance of a patent airway while maintaining cervical spine immobilization; B: evaluation of breathing, ventilation and oxygenation, immediate treatment of tension pneumothorax, open pneumothorax and massive hemothorax; C: evaluation and treatment of circulatory compromise and shock; D: Disability and Neurologic Status, assessment of signs of increased intracranial pressure and impending cerebral herniation; and E: Exposure while preventing hypothermia. Implementing these assessment and management priorities can result in more favorable outcomes
Evaluating clinical abdominal scoring system in predict- ing the necessity of laparotomy in blunt abdominal trauma
【Abstract】 Objectives: Trauma is among the lead-
ing causes of death. Medical management of blunt abdomi-
nal trauma (BAT) relies on judging patients for whom lap-
arotomy is mandatory. This study aimed to determine BAT
patients’ signs, as well as paraclinical data, and to clarify
the accuracy, sensitivity, specificity, positive and negative
predictive value of clinical abdominal scoring system
(CASS), a new scoring system based on clinical signs, in
predicting whether a BAT patient needs laparotomy or not.
Methods: Totally 400 patients suspected of BAT that
arrived at the emergency department of two university hos-
pitals in Tehran from March 20, 2007 to March 19, 2009 were
included in this study. They were evaluated for age, sex,
type of trauma, systolic blood pressure, Glasgow coma scale
(GCS), pulse rate, time of presentation after trauma, abdomi-
nal clinical findings, respiratory rate, temperature, hemoglo-
bin (Hb) concentration, focused abdominal sonography in
trauma (FAST) and CASS.
Results: Our measurements showed that CASS had
an accuracy of 94%, sensitivity of 100%, specificity of 88%,
positive predictive value of 90% and negative predictive
value of 100% in determining the necessity of laparotomy in
BAT patients. Moreover, in our analysis, systolic blood
pressure, GCS, pulse rate, Hb concentration, time of presen-
tation after trauma, abdominal clinical findings and FAST
were also shown to be helpful in confirming the need for
laparotomy (P<0.05).
Conclusion: CASS is a promising scoring system in
rapid detection of the need for laparotomy as well as in
minimizing auxiliary expense for further evaluation in BAT
patients, thus to promote the cost-benefit ratio and accu-
racy of diagnosis.

Echocardiography integrated ACLS protocol versus con-ventional cardiopulmonary resuscitation in patients with
【Abstract】Objective: To examine the utility of
bedside echocardiography in detecting the reversible causes
of pulseless electrical activity (PEA) cardiac arrest and pre-dicting the resuscitation outcomes.
Methods: In this prospective interventional study, pa-tients presenting with PEA cardiac arrest were randomized
into two groups. In Group A, ultrasound trained emergency
physicians performed echocardiography evaluating cardiac
activity, right ventricle dilation, left ventricle function, peri-cardial effusion/tamponade and IVC size along with the ad-vanced cardiac life support (ACLS) protocol. Patients in Group
B solely underwent ACLS protocol without applying
echocardiography. The presence or absence of mechanical
ventricular activity (MVA) and evidences of PEA reversible
causes were recorded. The return of spontaneous circulation
(ROSC) and death were evaluated in both groups.
Results: One hundred patients with the mean age of
(58±6.1) years were enrolled in this study. Fifty patients
(Group A) had echocardiography detected in parallel with
cardiopulmonary resuscitation (CPR). Among them, 7 pa-tients (14%) had pericardial effusion, 11 (22%) had
hypovolemia, and 39 (78%) were revealed the presence of
MVA. In the pseudo PEA subgroup (presence of MVA),
43% had ROSC (positive predictive value) and in the true
PEA subgroup with cardiac standstill (absence of MVA),
there was no recorded ROSC (negative predictive value).
Among patients in Group B, no reversible etiology was
detected. There was no significant difference in resuscitation
results between Groups A and B observed (P=0.52).
Conclusion: Bedside echocardiography can identify
some reversible causes of PEA. However, there are no sig-nificant changes in survival outcome between the echo
group and those with traditional CPR.
