The incidence of pancreatic injury following blunt abdominal trauma is rare. A timely accurate diagnosis of such injury is difficult and also the management remains controversial. Here, we reported the successful use of laparoscopy to diagnose, characterize and treat blunt pancreatic trauma in a 28-year-old male patient involved in a motor vehicle crash. An abdominal computed tomography scan showed peripancreatic fat stranding suggestive of pancreatic injury. With persistent clinical signs of peritonitis and laboratory investigations suggestive of pancreatitis, the patient underwent laparoscopic drainage of the lesser sac. The patient had an uneventful postoperative course. The management of patients with blunt pancreatic injuries should be tailored to individual situations. Our experience suggests that a timely laparoscopic management of traumatic pancreatic injury is safe approach in selected cases.
•Free air in the abdomen after blunt traumatic neck injury is very rare.•If pneumoperitoneum is suspected, exploratory laparotomy should be performed to rule out intraabdominal injury.•Conservative management for pneumoperitoneum in the absence of viscus perforation is still a safe option in carefully selected cases.
Blunt trauma as a cause of pneumoperitoneum is less frequent and its occurrence without a ruptured viscus is rarely seen.
PRESENTATION OF CASE
We report a case of blunt neck trauma in which a motorcycle rider hit a fixed object causing severe laryngotracheal injury. The patient developed pneumothorax bilaterally and had pneumoperitoneum despite no injury to the internal viscus. Bilateral chest tube drainage and abdominal exploratory laparotomy was performed.
Free air in the abdomen after blunt traumatic neck injury is very rare. If pneumoperitoneum is suspected in the presence of pneumothorax, exploratory laparotomy should be performed to rule out intraabdominal injury. As, there is no consensus for this plan yet, further prospective studies are warrant. Conservative management for pneumoperitoneum in the absence of viscus perforation is still a safe option in carefully selected cases.

Bispectral index (BIS) monitoring in multiple trauma patients has become a common practice in monitoring the sedation levels. We aimed to assess the utility of BIS in the trauma intensive care unit (ICU).
A prospective observational study was conducted in the trauma ICU at Hamad General Hospital in Qatar between 2011 and 2012. Patients were divided in two groups: Group I (without BIS monitoring) and Group II (with BIS monitoring). The depth of sedation was clinically evaluated with Ramsey Sedation Scale, changes in vital signs and Glasgow Coma Scale (GCS) level. Use of sedatives, analgesics, and muscle relaxants were also recorded. Data were compared using Chi-square and Student t-tests.
A total of 110 mechanically ventilated trauma patients were enrolled with a mean age of 36 ± 14 years. The rate of head injury was greater in Group I when compared with Group II (94% vs. 81%, P = 0.04). In comparison to Group I, patients in Group II had lower GCS and higher mean Injury Severity Score (ISS) (6.3 ± 2.5 vs. 7.4 ± 2.7 and 25.5 ± 8.5 vs. 21.2 ± 4.7, respectively, P = 0.03). The used midazolam dose was less in Group II in comparison to Group I (5.2 ± 2.3 vs. 6.1 ± 2.1, P = 0.03). Also, fentanyl dose was less in Group II (152 ± 58 vs. 187 ± 59, P = 0.004). The rate of agitation, failure of extubation and tracheostomy in Group II were lower than those in Group I, P = 0.001. The length of stay for patients Group I was longer (14.6 ± 7.1 vs. 10.2 ± 5.9 days) in comparison to group II, P = 0.001.
Management of multiple trauma patients in the trauma ICU with BIS monitoring was found to be associated with better outcomes. BIS monitoring is a guide for adjusting the dosage of sedative agents. It can also minimize agitation, failure of extubation, and length of stay in ICU.

The mechanism and outcome of traumatic abdominal injury (TAI) varies worldwide. Moreover, data comparing TAIs in each abdominal compartment are lacking. We aimed to assess from the academic point of view, TAI based on its anatomical compartments.
Patients & methods
We conducted a retrospective study for TAI patients between 2008 and 2011 in Qatar. Patients were categorized according to the involved anatomical compartment (C): intrathoracic (ITC), retroperitoneal (RPC), true abdomen (TAC), and pelvic abdomen (PAC) group. Chi Square test, One-Way ANOVA and multivariate regression analysis were appropriately performed.
Of 6,888 patients admitted to the trauma unit, 1,036 (15%) had TAI that were grouped as ITC (65%), RPC (15%), TAC (13%), and PAC (7%). The mean age was lowest in ITC (29 ± 13) and highest in TAC (34 ± 11) group, (P = 0.001). Motor vehicle crash was the main mechanism of injury in all groups except for PAC, in which fall dominated. Vast majority of expatriates had PAC and TAC injuries. The main abdominal injuries included liver (35%; ITC), spleen (32%; ITC) and kidneys (18%; RPC). Extra-abdominal injuries involved the head in RPC and ITC, lung in ITC and RPC and extremities in PAC. Mean ISS was higher in RPC and ITC. Abdominal AIS was higher in TAC injuries. Overall hospital mortality was 10%: RPC (15%), TAC (11%), ITC (9.4%) and PAC (1.5%). Concurrent traumatic brain injury (OR 5.3; P = 0.001) and need for blood transfusion (OR 3.03; P = 0.003) were the main independent predictors of mortality.
In addition to its academic value, the anatomical approach of TAI would be a complementary tool for better understanding and prediction of the pattern and outcome of TAI. This would be possible if further research find accurate, early diagnostic tool for this anatomical classification.

Trauma remains one of the leading causes of morbidity and mortality worldwide. Generally, the incidence of traumatic injuries is disproportionately high in males. However, trauma in females is underreported.
To study the epidemiology and outcome of different mechanisms and types of traumatic injuries in women.
We conducted a traditional narrative review using PubMed, MEDLINE and EMBASE, searching for English-language publications for gender-specific trauma between January 1993 and January 2013 using key words “trauma”, “gender”, “female” and “women”.
Among 1150 retrieved articles, 71 articles were relevant over 20 years. Although it is an important public health problem, traumatic injuries among females remain under-reported.
There is a need for further research and evaluation of the exact burden of traumatic injuries among females together with the implementation of effective community based preventive programs.

Degloving soft-tissue injuries are serious and debilitating conditions. Deciding on the most appropriate treatment is often difficult. However, their impact on patients’ outcomes is frequently underestimated.
We aimed to study the incidence, clinical presentation, management and outcome of degloving soft-tissue injuries.
Materials and Methods:
We conducted a narrative traditional review using the key words; degloving injury and soft-tissue injuries through search engines PubMed, Science Direct, and Scopus.
There are several therapeutic options for treating degloving soft-tissue injuries; however, no evidence-based guidelines have been published on how to manage degloving soft-tissue injuries, although numerous articles outline the management of such injuries.
Degloving soft-tissue injuries are underreported and potentially devastating. They require early recognition, and early management. A multidisciplinary approach is usually needed to ensure the effective rehabilitation of these patients.

To determine the causes, predictors and outcomes of re-intubation.
Retrospective analysis of data collected from the trauma data base registry was conducted to identify the extubation failure cases in Trauma ICU at Hamad General Hospital, the only Level I trauma center in Qatar between January 2009 and December 2010. Demographics, mechanism of Injury, complications, injury severity score (ISS), Glasgow Coma Scale (GCS), ICU-length of stay (LOS), and mortality were analyzed among trauma patients who need reintubation within 48 hrs after extubation (group 1) compared to successfully extubated patients (group 2).
A total of 954 patients were admitted to the trauma ICU, of which 343 were intubated orotracheally. The mean age of patients was 32±12 years with male predominance (95%). Motor vehicle crash (41%), pedestrian injury (20%) and falls (18%) were the most common mechanisms of injury. Reintubation (group 1) was required in 24 patients (7%). Patients in group 1 had higher rate of head injury mainly SAH (88%), pneumonia (79%) and pulmonary contusion (58%). The mean ICU-LOS was higher in the reintubated patients (p=0.010) in comparison to group 2. Forty-six percent of reintubated patients required tracheostomy. The mean age, ISS, GCS and tube size was comparable among the two groups. Furthermore, reintubation was not associated with higher mortality rate (p=0.910). However, Ventilator-associated pneumonia (VAP) (odd ratio=3.61 [95% CI 1.25-10.44]; p=0.020) and ventilator days (odd ratio=1.09 [95% CI 1.024-1.153]; p=0.006) were independent predictors of reintubation by multivariate analysis.
Re-intubation is associated with increased ICU-LOS and need for tracheostomy. VAP and prolonged intubation are independent predictors of re-intubation. Our finding addresses the value of prevention and early treatment of infection in intubated patients. This study may represent an audit of local practice as well.

Blunt esophageal injuries secondary to external air compression of anterior chest and abdomen complicated with esophageal perforation are uncommon events associated with worse outcomes.
PRESENTATION OF CASE
We reported a rare case of esophageal perforation following an external air-compression injury along with the relevant review of literatures. The patient presented with chest pain and shortness of breath and was managed with tube thoracostomy, followed by thoracotomy and eventually with temporary endoscopic stenting.
In such trauma case, the external pressurized air forms a shock wave which usually directed to the hollow viscus. Patients with external air-compression injury presented with chest pain and pneumothorax should be suspected for esophageal perforation.
High index of suspicion is needed for early diagnosis of esophageal perforation after blunt trauma. Appropriate drainage, antibiotic and temporary endoscopic esophageal stenting may be an optimal approach in selected patients, especially with delayed diagnosis.

Elderly patients have more cardiovascular risk factors and a greater burden of ischemic disease than younger patients.
To examine the impact of age on clinical presentation and outcomes in patients presenting with acute coronary syndrome (ACS).
Methods and material
Collected data from the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2), which is a prospective multicenter study from six adjacent Arab Middle Eastern Gulf countries. Patients were divided into 3 groups according to their age: ≤50 years, 51–70 years and >70 years and their clinical characteristics and outcomes were analyzed. Mortality was assessed at one and 12 months.
Statistical analysis used
One-way ANOVA test for continuous variables, Pearson chi-square (X2) test for categorical variables and multivariate logistic regression analysis for predictors were performed.
Among 7930 consecutive ACS patients; 2755 (35%) were ≤50 years, 4110 (52%) were 51–70 years and 1065 (13%) >70 years old. The proportion of women increased with increasing age (13% among patients ≤50 years to 31% among patients > 70 years). The risk factor pattern varied with age; younger patients were more often obese, smokers and had a positive family history of CAD, whereas older patients more likely to have diabetes mellitus, hypertension, and dyslipidemia. Advancing age was associated with under-treatment evidence-based therapies. Multivariate logistic regression analysis after adjusting for relevant covariates showed that old age was independent predictors for re-ischemia (OR 1.29; 95% CI 1.03–1.60), heart failure (OR 2.8; 95% CI 2.17–3.52) and major bleeding (OR 4.02; 95% CI 1.37–11.77) and in-hospital mortality (age 51–70: OR 2.67; 95% CI 1.86–3.85, and age >70: OR 4.71; 95% CI 3.11–7.14).
Despite being higher risk group, elderly are less likely to receive evidence-based therapies and had worse outcomes. Guidelines adherence is highly recommended in elderly.

Pneumomediastinum (PM) is mainly an atypical finding among traumatic neck or thoracic injury patients. Moreover, PM secondary to isolated orbital floor fracture remains a rare event which is infrequently associated with severe complications such as mediastinitis, airway obstruction and pneumothorax. Herein, we report an atypical case of mediastinal emphysema consequent to orbital floor fracture along with review of the literature.
We aimed to define the temporal trend in the initial Acute Myocardial Infarction (AMI) management and outcome during the last two decades in a Middle Eastern country. A total of 10,915 patients were admitted with initial AMI with mean age of 53 ± 11.8 years. Comparing the two decades (1991–2000) to (2001–2010), the use of antiplatelet drugs increased from 84% to 95%, β-blockers increased from 38% to 56%, and angiotensin converting enzyme inhibitors (ACEI) increased from 12% to 36% (P < 0.001 for all). The rates of PCI increased from 2.5% to 14.6% and thrombolytic therapy decreased from 71% to 65% (P < 0.001 for all). While the rate of hospitalization with Initial MI increased from 34% to 66%, and the average length of hospital stay decreased from 6.4 ± 3 to 4.6 ± 3, all hospital outcomes parameters improved significantly including a 39% reduction in in-hospital Mortality. Multivariate logistic regression analysis showed that higher utilization of antiplatelet drugs, β-blockers, and ACEI were the main contributors to better hospital outcomes. Over the study period, there was a significant increase in the hospitalization rate in patients presenting with initial AMI. Evidence-based medical therapies appear to be associated with a substantial improvement in outcome and in-hospital mortality.
Trauma represents a global public health concern with an estimated 5 million deaths annually. Moreover, the incidence of blunt traumatic injuries (BTI) particularly road traffic accidents (RTAs) and workplace-related injuries are rising throughout the world-wide. Objectives: We aimed to review the epidemiology and prevention of BTI, in the Arab Middle East.
Materials and Methods:
A traditional narrative literature review was carried out using PubMed, MEDLINE and EMBASE search engines. We used the keywords “traumatic injuries”, “blunt” “epidemiology”, “Arab Middle East” between December 1972 and March 2013.
The most common mechanisms of BTI in our region are RTAs, falls from height, struck by heavy objects and pedestrian motor vehicle trauma crashes. The rate of RTA and occupational injuries are markedly increased in the region due to rapid industrial development, extreme climatic conditions and unfamiliar working environment. However, lack of reliable information on these unintentional injuries is mainly responsible for the underestimation of this trauma burden. This knowledge deficit shields the extent of the problem from policy makers, leading to continued fatalities. These preventable injuries in turn add to the overall financial burden on the society through loss of productivity and greater need of medical and welfare services.
In the Arab Middle East, population-based studies on the incidence, mechanism of injury, prevention and outcome of BTI are not well-documented. Therefore, region-specific BTI studies would strengthen surveillance to better understand the burden of these injuries in the region.

Traumatic workplace-related injuries (WRIs) carry a substantial negative impact on the public health worldwide. We aimed to study the incidence and outcomes of WRIs in Qatar. We conducted occupational injury surveillance for all WRI patients between 2010 and 2012. A total of 5152 patients were admitted to the level 1 trauma unit in Qatar, of which 1496 (29%) sustained WRI with a mean age of 34.3 ± 10.3. Fall from height (FFH) (51%) followed by being struck by heavy objects (FHO) (18%) and motor vehicle crashes (MVC) (17%) was the commonest mechanism of injury (MOI). WRI patients were mainly laborers involved in industrial work (43%), transportation (18%), installation/repair (12%), carpentry (9%), and housekeeping (3%). Use of protective device was not observed in 64% of cases. The mean ISS was 11.7 ± 8.9, median ICU stay was 3 days (1–64), and total hospital stay was 6 days (1–192). The overall case fatality was 3.7%. Although the incidence of WRI in Qatar is quite substantial, its mortality rate is relatively low in comparison to other countries of similar socioeconomic status. Prolonged hospital stay and treatment exert a significant socioeconomic burden on the nation's and families' resources. Focused and efficient injury prevention strategies are mandatory to prevent future WRI.
Foot ulceration (FU) remains a serious concern for patients worldwide. We analyzed the incidence, risk factors, and outcome of FU in hemodialysis (HD) patients. A retrospective cohort study was conducted for 252 HD patients who were followed up for 5 years. Patients were categorized according to whether they developed FU or not. The FU group (17%) was older and had significantly higher incidence of nephropathy, retinopathy, peripheral (PAD), coronary artery disease (CAD), and diabetes mellitus (DM) as compared to no-FU group. FU group had higher frequency of major amputation (P = 0.001) and HD vascular access (P = 0.01). Patients with combined DM and PAD had a 10-fold increased risk of FU in comparison to those who had DM alone. Presence of PAD was the main independent predictor for development of FU in HD with an adjusted odd ratio (aOR) of 16.0 (95% CI: 4.41–62.18; P = 0.001). After adjusting for age, sex, and CAD, predictors for mortality were PAD (aOR 4.3), FU (aOR 3.6), and DM (aOR 2.6). FU is common in HD patients regardless of DM. However, the presence of PAD is significantly associated with more FU and mortality in HD. HD patients need intensive foot care and warrant progressive modification of vascular risk factors.
We aimed to evaluate the frequency, clinical profiles and outcomes of abdominal aortic aneurysms (AAA), and their association with coronary artery disease (CAD) in a small country with high cardiovascular burden. Methods. Data were collected for all adult patients who underwent abdominal computed tomography scans at Hamad General Hospital in Qatar between 2004 and 2008. Results. Out of 13,115 screened patients for various reasons, 61 patients (0.5%) had abdominal aneurysms. The majority of AAA patients were male (82%) with a mean age of 67 ± 12 years. The incidence of AAA substantially increased with age reaching up to 5% in patients >80 yrs. Hypertension was the most prevalent risk factor for AAA followed by smoking, dyslipidemia, renal impairment, and diabetes mellitus. CAD and peripheral arterial disease (PAD) were observed in 36% and 13% of AAA patients, respectively. There were no significant correlations between CAD or PAD and site and size of AAA. Conclusion. This is the largest study in our region that describes the epidemiology of AAA with concomitant CAD. As the mortality rate is quite high in this high risk population, routine screening for AAA in CAD patients and vice versa needs further studies for proper risk stratification.
Rollover car crashes (ROCs) are serious public safety concerns worldwide. Objective. To determine the incidence and outcomes of ROCs with or without ejection of occupants in the State of Qatar. Methods. A retrospective study of all patients involved in ROCs admitted to Level I trauma center in Qatar (2011-2012). Patients were divided into Group I (ROC with ejection) and Group II (ROC without ejection). Results. A total of 719 patients were evaluated (237 in Group I and 482 in Group II). The mean age in Group I was lower than in Group II (24.3 ± 10.3 versus 29 ± 12.2; P = 0.001). Group I had higher injury severity score and sustained significantly more head, chest, and abdominal injuries in comparison to Group II. The mortality rate was higher in Group I (25% versus 7%; P = 0.001). Group I patients required higher ICU admission rate (P = 0.001). Patients in Group I had a 5-fold increased risk for age-adjusted mortality (OR 5.43; 95% CI 3.11–9.49), P = 0.001). Conclusion. ROCs with ejection are associated with higher rate of morbidity and mortality compared to ROCs without ejection. As an increased number of young Qatari males sustain ROCs with ejection, these findings highlight the need for research-based injury prevention initiatives in the country.
Objectives. To study the effect of prehospital intubation (PHI) on survival of patients with isolated severe traumatic brain injury (ISTBI). Method. Retrospective analyses of all intubated patients with ISTBI between 2008 and 2011 were studied. Comparison was made between those who were intubated in the PHI versus in the trauma resuscitation unit (TRU). Results. Among 1665 TBI patients, 160 met the inclusion criteria (105 underwent PHI, and 55 patients were intubated in TRU). PHI group was younger in age and had lower median scene motor GCS (P = 0.001). Ventilator days and hospital length of stay (P = 0.01 and 0.006, resp.) were higher in TRUI group. Mean ISS, length of stay, initial blood pressure, pneumonia, and ARDS were comparable among the two groups. Mortality rate was higher in the PHI group (54% versus 31%, P = 0.005). On multivariate regression analysis, scene motor GCS (OR 0.55; 95% CI 0.41–0.73) was an independent predictor for mortality. Conclusion. PHI did not offer survival benefit in our group of patients with ISTBI based on the head AIS and the scene motor GCS. However, more studies are warranted to prove this finding and identify patients who may benefit from this intervention.
The impact of prehospital intubation (PHI) in improving outcome of trauma patients has not been adequately evaluated in the developing countries.
The present study analyzed the outcome of PHI versus emergency room intubation (ERI) among trauma patients in Qatar.
Materials and Methods:
Data were retrospectively reviewed for all intubated trauma patients between 2010 and 2011. Patients were classified according to location of intubation (PHI: Group-1 versus ERI: Group-2). Data were analyzed and compared.
Out of 570 intubated patients; 482 patients (239 in group-1 and 243 in group-2) met the inclusion criteria with a mean age of 32 14.6 years Head injury (P = 0.003) and multiple trauma (P = 0.004) were more prevalent in group-1, whereas solid organ injury predominated in group-2 (P = 0.02). Group-1 had significantly higher mean injury severity scoring (ISS), lower Glasgow coma scale (GCS), greater head abbreviated injury score and longer activation, response, scene and total emergency medical services times. The mortality was higher in group-1 (53% vs. 18.5%; P = 0.001). Multivariate analysis showed that GCS [odds ratio (OR) 0.78, P = 0.005) and ISS (OR 1.12, P = 0.001) were independent predictors of mortality.
PHI is associated with high mortality when compared with ERI. However, selection bias cannot be ruled out and therefore, PHI needs further critical assessment in Qatar.

Management of liver injury is challenging particularly for the advanced grades. Increased utility of nonoperative management strategies increases the risk of developing massive liver necrosis (MLN). We reported a case of a 19-year-old male who presented with a history of motor vehicle crash. Abdominal computerized tomography (CT) scan revealed large liver laceration (Grade 4) with blush and moderate free hemoperitoneum in 3 quadrants. Patient was managed nonoperatively by angioembolization. Two anomalies in hepatic arteries origin were reported and both vessels were selectively cannulated and bilateral gel foam embolization was achieved successfully. The patient developed MLN which was successfully treated conservatively. The follow-up CT showed progressive resolution of necrotic areas with fluid replacement and showed remarkable regeneration of liver tissues. We assume that patients with high-grade liver injuries could be managed successfully with a carefully designed protocol. Special attention should be given to the potential major associated complications. A tailored multidisciplinary approach to manage the subsequent complications would represent the best recommended strategy for favorable outcomes.
Objectives. To assess the standard practice of care of surgeons regarding surgical antibiotic prophylaxis, to identify gaps, and to set recommendations. Methods. A retrospective analysis of data obtained from different surgical units in a single center in Qatar over a 3-month period in 2012. A total of 101 patients who underwent surgery and followed regimes for surgical prophylaxis as per hospital guidelines were included in the study. Results. The overall use of antibiotic was 89%, whereas the current practice did not match the recommended hospital protocols in 53.5% of cases. Prolonged antibiotics use (59.3%) was the commonest reason for nonadherence followed by the use of an alternative antibiotic to that recommended in the protocol (31.5%) and no prophylaxis was used in 9.2% of cases. The rate of compliance was significantly higher among clean surgery than clean contaminated group (P = 0.03). Forty-four percent of clean and 65% of clean-contaminated procedures showed noncompliance with the recommended surgical antimicrobial prophylaxis hospital guidelines. Conclusion. Lack of adherence to hospital protocols is not uncommon. This finding remains a challenge to encourage clinicians to follow hospital guidelines appropriately and to consistently apply the surgical antibiotic prophylaxis. The role of clinical pharmacist may facilitate this process across all surgical disciplines.
Adult intussusception (AI) following blunt abdominal trauma (BAT) is a rare surgical condition. We present a case of delayed diagnosis of ileocecal junction intussusception with a perforation of small bowel in a 34-year-old male with a history of fall from height. Initial exploratory laparotomy revealed shattered spleen requiring splenectomy. Initial abdominal computerized tomography scanning (CT) scan showed dilated small bowel with no organic obstruction. Patient started to improve with partial distention and was shifted to rehabilitation unit. On the next day, he experienced severe abdominal distention and vomiting. Abdominal CT showed characteristic intussusception at the distal ileum. Secondary exploratory laparotomy revealed severe adhesions of stomach and small bowel to the anterior abdominal wall with dilated small bowel loops and intussusception near the ileocecal junction with perforation of small bowel. The affected area was resected and side-to-side stapled anastomosis was performed. Though small bowel intussusception is a rare event, BAT patients with delayed symptoms of bowel obstruction should be carefully evaluated for missed intussusception.
Background and Aims:
Withholding findings of clinical trials for publication or presentation to the regulatory authorities is a major concern. We aimed to address the importance of clinical trial registration and whether it is needed or not.
For ethical conduct of clinical trial, registration is an important but debatable issue due to proprietary interest of the pharmaceutical industry. Over the years, investigating agencies uncovered several instances of misconduct during the clinical trial. The International committee of medical journal editors requires registration of trial methodology, but does not require registration of trial results; however, the U.S. Food and Drug Administration Amendments does require researchers to register results.
Prospective registration of clinical trial is mandatory for more transparent research and sustaining the validity of evidence based practice and availability of reliable data. Clinical trials registration has the potential to contribute substantially to improve clinical trial transparency and reducing publication bias and selective reporting.

Blunt esophageal injury is extremely rare event. However, it is a potential morbid injury unless managed early.
PRESENTATION OF CASE
We report a rare case of blunt esophageal injury for a 28-year old male who presented with history of fall of heavy object over the right side of the chest. Diagnostic work up including chest X-ray, computerized tomography scans and gastrografin esophagogram revealed lower esophageal rupture. Right mini-thoracotomy with esophageal repair was performed. Postoperative course was uneventful.
The exact mechanism of blunt esophageal injury remains uncertain. This report described a unique location of esophageal rupture after blunt trauma that happened on the right side. Diagnosis of esophageal injury needs high index of suspicion and accurate diagnostic workup.
Prompt diagnosis and management are the key for better prognosis in patients with blunt esophageal injury.

Peripheral arterial disease (PAD) is a common manifestation of systemic atherosclerosis and is associated with significant morbidity and mortality. The prevalence of PAD in the developed world is approximately 12% among adult population, which is age-dependent and with men being affected slightly more than women. Despite the strikingly high prevalence of PAD, the disease is underdiagnosed. Surprisingly, more than 70% of primary health care providers in the US were unaware of the presence of PAD in their patients. The clinical presentation of PAD may vary from asymptomatic to intermittent claudication, atypical leg pain, rest pain, ischemic ulcers, or gangrene. Claudication is the typical symptomatic expression of PAD. However, the disease may remains asymptomatic in up to 50% of all PAD patients. PAD has also been reported as a marker of poor outcome among patients with coronary artery disease. Despite the fact that the prevalence of atherosclerotic disease is increasing in the Middle East with increasing cardiovascular risk factors (tobacco use, diabetes mellitus and the metabolic syndrome), data regarding PAD incidence in the Middle East are scarce.

Background. Khat chewing is a common habit in Yemen despite increased evidence of its negative impact on the cardiovascular system. Aims. We aimed to study the epicardial coronary arteries in khat chewers presenting with myocardial infarction (AMI). Materials and Methods. A descriptive, cross-sectional study was conducted between November 2008 and May 2009 in Yemen. AMI patients who underwent coronary angiogram were enrolled and divided into groups (gp): gp1 (diabetic and khat chewers), gp2 (khat chewers and nondiabetic), and gp3 (diabetic and non-khat users). Results. Of 347 AMI patients 63%, 21%, and 16% were in gp 2, 3, and 1, respectively. Khat chewers were younger in comparison to non-khat users. Group 3 patients were more likely to have multivessel disease, severe left anterior descending (LAD), right coronary artery (RCA) stenosis and total RCA, and left circumflex (Lcx) occlusion compared to other groups. Group 1 patients were more likely to have total LAD occlusion and severe Lcx lesions. In multivariate analysis, age, diabetes mellitus, and smoking were significant independent predictors for significant coronary artery lesions; however, khat chewing did not show such association. Conclusions. Coronary spasm is the main mechanism of AMI in khat chewers. The impact of our finding for risk stratification and management warrants further studies.
