To determine the results of the conservative approach in the treatment of pediatric abdominal trauma, we retrospectively analyzed data from the files of 95 cases of abdominal trauma in children during a 5-year period.

51 patients (54%) had isolated abdominal injury, while 44 (46%) had multiple trauma. The most common causes of injury were road accidents and falls from heights (74%). CT scans were performed in 61 (64%) with positive results in 90%. Ultrasonography was done in 22 (23%) and was positive in 55%.

The spleen was the most vulnerable intra-abdominal organ (33 patients, 35%), as well as the organ most severely damaged. Other injured organs were: liver (30 cases), kidney (16), stomach (2), large blood vessels (2), and pancreas, duodenum and diaphragm (1 case each).

83 patients (87%) were treated conservatively, while 11 were operated on for penetrating abdominal trauma (3 cases), hemodynamic instability (3), positive DPL (3), and Scale 4 splenic injury and free intra-abdominal air on CT scan (1 case each). Early and late complications were mild.

It is concluded that CT is an efficient and reliable imaging method for diagnosis and staging of severity of injury in blunt abdominal trauma. Nonoperative management of solid organ injuries under careful observation in a pediatric trauma center is safe and appropriate. Most Scale 4 splenic injuries can be treated successfully without surgical intervention. Using this conservative approach there were no late complications.

Major pancreatic trauma challenges the trauma surgeon with diagnostic problems and choices of treatment modalities. The most important determinant guiding management is the integrity of the main pancreatic duct. The preoperative and intraoperative assessment and treatment of pancreatic injury may be difficult, especially when concurrent severe injuries are present. There are alternative approaches in the management of the traumatized pancreas when ductal injury is not obvious during initial exploratory laparotomy.

Arterio-venous fistula is a relatively rare form of vascular injury. A cof an unusual fistula between aorta and inferior vena cava is presented. Occasionally this type of is difficult to diagnose early. Life-threatening conditions may mandate prompt treatment and the use of damage control strategy. It is also important to diagnose and treat this injury in order to prevent complications. Sudden hemorrhage and congestive heart failure are the major disturbances that result from aortocaval fistula.

Spectral analysis of heart rate variability (HRV) has been shown to be a reliable noninvasive test for quantitative assessment of cardiovascular autonomic regulatory response, providing a dynamic map of sympathetic and parasympathetic interaction. In a prior study exploring the state of hyperarousal that characterizes the post traumatic stress disorder (PTSD) syndrome, we presented standardized heart rate analyses in 9 patients at rest, which demonstrated clear-cut evidence of a baseline autonomic hyperarousal state.

To examine the dynamics of this hyperarousal state, standardized heart rate analysis was carried out in 9 PTSD patients, compared to a matched control group of 9 normal volunteers. 20-minute ECG recordings in response to a trauma-related cue, as opposed to the resting state, were analyzed. The patients were asked to recount the presumed triggering traumatic event, and the control subjects recounted a significant stressful negative life event.

Whereas the control subjects demonstrated significant autonomic responses to the stressogenic stimulus of recounting major stressful experiences, the patients demonstrated almost no autonomic response to the recounting of the triggering stressful event. The patients demonstrated a degree of autonomic dysregulation at rest comparable to that seen in the control subjects' reaction to the stress model.

The lack of response to the stress model applied in the study appears to imply that PTSD patients experience so great a degree of autonomic hyperactivation at rest, that they are unable to marshal a further stress response to the recounting of the triggering trauma, as compared to control subjects. A subsequent study of the effect of medication on these parameters showed that they are normalized by use of selective serotonin re-uptake inhibitors (SSRI's).

Neither the clinical implications of these findings, nor their physiological mechanisms are clear at present. We presume that they reflect a central effect, as the peripheral automatic effects of SSRI's are relatively negligible.

Rupture of the pectoralis major muscle in an athlete is rare, but is said to be common in weight lifters. The muscle usually ruptures at the musculotendinous junction during forceful contraction of the muscle in adduction, forward flexion and internal rotation of the arm. We describe an athlete who suffered such a major tear during a rugby game. It was treated surgically and after adequate rehabilitation, athletic activities were resumed.

Popliteal Vascular Trauma

6 cases of popliteal vascular trauma are presented, 3 due to posterior dislocation of the knee and 3 due to crush injury. The patients were referred from another hospital and some had undergone unnecessary angiography when ischemia was present, leading to delay in surgery. All patients presented with distal ischemia and underwent reconstructive surgery; 2 subsequently underwent below-knee amputation because of irreversible ischemia and sepsis.

Urgent operation for popliteal vascular trauma is necessary whenever there is ischemia and intraoperative angiography may be necessary. There should be reconstruction of the artery and vein when there is concomitant venous damage, and fasciotomy and debridement are important. The harmful potential of occult popliteal vascular injuries and their ostensible mild presentation present a challengfor the emergency room surgeon.

The purpose of orthopedic joint implants is to improve joint movement. Within the past 30 years, biomechanical improvements affecting the life-span of the implants has brought a new type of problem: the biological response to debris from the implant material contributes greatly to aseptic loosening of the prosthesis. The process is mediated by osteotropic factors, cytokines released from mononuclear cells, and osteoblasts and osteoclasts in the bone-cement interface or bone-implant interface.

Abdominal compartment syndrome refers to a complex of negative effects of intra-abdominal hypertension. Its most common cause is complicated abdominal trauma. The syndrome includes mainly hemodynamic and respiratory manifestations but may involve other systems as well. It may present as a life-threatening emergency in the multi-trauma patient. Awareness of the syndrome may enable the surgeon to take preventive measures or to diagnose it earlier and to treat it effectively. We describe a 21-year old man who developed this syndrome after multiple gunshot wounds, with severe liver injury. After 2 operations the typical manifestations of the syndrome were diagnosed. He was re-operated to release intra-abdominal hypertension and then slowly recovered.

Insufficiency fractures of the pelvis may be overlooked as a cause of hip or groin pain. These fractures occur in the elderly, usually those with pronounced osteopenia of the pelvis. Predisposing factors include corticosteroids, local irradiation and postmenopausal osteoporosis. These fractures are difficult to detect clinically and plain radiographs and other studies may be misleading, delaying diagnosis and treatment. A 65-year-old woman had left groin and hip pain for 2 months with no history of trauma. Plain radiographs showed lytic lesions in the left pubic rami. Bone scan revealed increased uptake in that region, suggesting metastatic bone disease. Computed tomography and magnetic resonance imaging demonstrated fractures in the left superior and inferior pubic rami, with callus formation with no involvement of soft tissues. Quantitative computed tomography indicated low calcium concentration, below fracture threshold. The diagnosis of insufficiency fractures of the pelvis was confirmed by the favorable clinical and radiographic outcome. It is therefore important to be familiar with the appearance and location of these fractures.

Traumatic Hyphema*

Traumatic hyphema usually occurs in young men at the rate of 17-20/1000,000. Major complications include secondary hemorrhage, glaucoma, corneal staining and disturbances in visual acuity. Final visual acuity is predominantly the outcome of all the ocular injuries occurring during the trauma, mainly to the posterior segment of the eye. We describe all cases of traumatic hyphema treated in our department over a period of 3.5 years. Antifibrinolytic treatment is recommended in the literature in traumatic hyphema to prevent secondary hemorrhage. Our findings differ from those in the literature in that they show a lower prevalence of more severe hemorrhages and of secondary hemorrhage. In light of these differences, and with regard to possible side effects of such treatment, we suggest that antifibrinolytic treatment not be used in our population. We recommend that treatment for traumatic hyphema should include restricted activity, local corticosteroidal preparations, frequent follow-up visits and vigorous diagnostic work-up in order to find any additional eye damage. We strongly recommend the use of preventive measures (eye-shields) in high risk activities such as sports, house-hold work and military training.

This department was established 35 years ago. Since then, many patients with facial trauma, both soldiers and civilians, have been treated and extensive experience has been accumulated. From 1990 to 1995, 487 patients with facial trauma (18.6% of the patients in the department) where hospitalized and treated. 88.5% suffered from injuries which included facial bones, and the others from soft tissue injuries only. We summarize our experience, analyzing both the demographic and clinical characteristics of the injuries and the treatment administered. Based on our experience and the current literature, we present an overview of the issue.

The visual outcome in 23 men and 2 women with traumatic cataracts was analyzed retrospectively. Their average age was 33 and they ranged from 10 to 69 years. Surgical results were either very good or very poor. Associated retinal injuries significantly decreased final visual acuity (p = 0.001). Those with initial visual acuity restricted to finger counting had better visual results than those with initial visual acuity restricted to light perception (p = 0.01) and hand motions (p = 0.02). Usually the lens was removed via the pars plana; the most common mode of optical correction was contact lenses.
