[Blunt heart injuries].

Cardiac injuries were present in 16% of our patients suffering from blunt chest trauma. 25% of these cases had no concomitant rib fractures. Sonography is extremely important for evaluation. In myocardial contusion the electrocardiogram reveals mainly disturbances in repolarisation (66 out of 108 patients) and rhythm disturbances (59 patients). A ratio of CK-MB isoenzyme/total CK of over 8% is highly suggestive of myocardial injury. Continuous monitoring in ICU is mandatory. Prognosis is mainly based on additional injuries. Heart wall rupture and luxation of the heart require operative treatment. Lesions of the aortic valves are the most frequent valve injuries.

Early and late onset bacteremia have different risk factors in trauma patients.

OBJECTIVE: The aim of this study was to identify risk factors and to describe epidemiological patterns for early-(EOB) and late-onset bacteremias (LOB) after trauma. DESIGN: A prospective study conducted on 141 consecutive trauma patients. SETTING: A general intensive care unit (ICU) of a university hospital. PATIENTS: All multiple trauma patients admitted to our general intensive care unit (ICU) from December 1990 to May 1992 were prospectively enrolled in the study. The following information was collected for each patient and recorded in a computer database: demography, severity of trauma according to the Abbreviated Injury Scale (AIS), severity of coma according to the Glasgow Coma Scale (GCS), presence of pneumothorax, pulmonary contusion, rib fractures, hemothorax, and abdominal trauma, use of mechanical ventilation, and placement of central venous catheters. Bacteremias were defined as EOB when onset occurred within 96 h after trauma, and as LOB when appearing after 96 h from trauma. RESULTS: Thirty-seven patients developed bacteremia during their ICU stay (26%): 11 (29.7%) EOB and 26 (70.3%) LOB. Gram-positive cocci were isolated more frequently in EOB than in LOB (chi 2 = 4.1, P = 0.04). The risk of EOB was significantly increased by the presence of pulmonary contusion [relative risk (RR) 15.0; confidence interval (CI) 1.99-113.25], pneumonia before the onset of bacteremia (RR 3.56; CI 1.17-10.69), AIS score greater than 32 and an abdominal injury score greater than 9 (RR 3.11; CI 1.02-9.49), while intravascular catheters and mechanical ventilation did not represent risk factors for EOB. LOB had a very different pattern and their risk was significantly increased by exposure to intravascular catheters (RR 4.96; CI 1.23-19.94) and to mechanical ventilation lasting more than 7 days (RR 3.6; CI 1.6-8.1). CONCLUSIONS: Scoring with the AIS of the abdominal and thoracic trauma at admission to the ICU appears a useful tool for identifying trauma patients at increased risk of EOB. A rigorous policy of catheter placement and maintenance as a means of reducing late bacteremias in trauma patients is essential.

A "hole in a rib" as a sign of child abuse.

Cyst-like radiolucencies ("holes") in ribs can be a manifestation of many different abnormalities. Two cases of child-abuse are presented in which the initial clue leading to the diagnosis of a battered-child was a cyst-like lytic lesion in the posterior rib cage.

Total body calcium measurements using neutron-activation analysis in Cushing's syndrome.

Total body calcium content (TBCa) was estimated by in vivo neutron activation analysis in 16 patients (14 female, 2 male) with active Cushing's syndrome, pituitary driven in all but two cases. Apart from being nonreproductive, patients were unselected. TBCa was below the predicted young normal value in all patients (mean +/- SD, 85.2 +/- 5.8% of predicted, P less than 0.01 vs. predicted) and in 13 of the 16 patients, was also below the predicted value when allowance was made for expected postmenopausal skeletal losses (mean +/- SD, 92.7 +/- 12.5% of predicted, P less than 0.02). However, individual values of TBCa were significantly lower (P less than or equal to 0.05) than the predicted normal range, corrected for postmenopausal losses, in only 3 patients (19% of the group). Initial TBCa apparently was not related to duration of the disease or to current urinary-free cortisol levels. At presentation, radiographic signs of significant osteoporosis (multiple vertebral and/or rib fractures) were present in four patients, three of whom had subnormal or borderline TBCa compared with the young normal predicted range. TBCa measurements were repeated in 9 patients 1-10 years after successful treatment, and were generally unchanged. During this period, only one vertebral fracture (consistent with simple postmenopausal osteoporosis) appeared in these patients. We conclude that bone mass tends to be low in newly diagnosed Cushing's syndrome, but that significant reduction beyond expected postmenopausal losses is relatively uncommon.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term complications associated with breast-conservation surgery and radiotherapy.

BACKGROUND: Breast-conservation surgery plus radiotherapy has become the standard of care for early-stage breast cancer; we evaluated its long-term complications. METHODS: We selected patients treated with surgery and radiotherapy between January 1990 and December 1992 (an era in which standard radiation dosages were used) with follow-up for at least 1 year. Patients were prospectively monitored for treatment-related complications. Median follow-up time was 89 months. RESULTS: A total of 294 patients met the selection criteria. Grade 2 or higher late complications were identified in 29 patients and included arm edema in 13 patients, breast skin fibrosis in 12, decreased range of motion in 4, pneumonitis in 2, neuropathy in 2, fat necrosis in 1, and rib fracture in 1. Arm edema was more common after lumpectomy plus axillary node dissection than after lumpectomy alone. Arm edema occurred in 18% of patients who underwent surgery plus irradiation of the lymph nodes and 10% who underwent surgery without nodal irradiation. CONCLUSIONS: Breast-conservation surgery plus radiotherapy was associated with grade 2 or higher complications in only 9.9% of patients. Half of these complications were attributable to axillary dissection, it is hoped that lower complication rates can be achieved with sentinel lymph node biopsy. Breast-conservation surgery and radiotherapy is associated with grade 2 or greater complications in only 9.9% of patients. Nearly half of these complications are attributable to axillary dissection.

[A case of traumatic aneurysm of the brachiocephalic artery].

Traumatic aneurysm of the brachiocephalic artery is rate. We presented a case of traumatic aneurysm of the brachiocephalic artery caused by traffic accident. A 28-year-old woman suffered a blunt chest trauma. A chest X-ray revealed a widening of the superior mediastinum and multiple rib fractures. CT scanning demonstrated left hemothorax with lung contusion and upper mediastinal hematoma. An aortography was performed which showed aneurysmal dilatation at the origin of the brachiocephalic artery. The patient underwent an operation 24 hours after chest injury. An aorto-right common carotid artery and right subclavian artery bypass with bifurcated Dacron graft was performed while monitoring temporary artery pressure. After resection of aneurysm, We found that about 3 cm longitudinal laceration of intima on the posterior wall of brachiocephalic artery. Her post operative condition was good and no neurological defect was noted.

[Blunt thoracic injury].

Of 161 patients with blunt thoracic injury, 135 were male (83.9%) and 26 were female. The most common cause of injury was traffic accidents (130 patients, 80.7%), followed by falls (22 patients), and crushing (7 patients). There were 46 third decade and 36 second decade patients. Thirty-two patients had single thoracic injury and the other had multiple organ injury. The most common associated injury was head injury (65 patients). Most traffic accidents involved motor cycle accident. Forty-four patients died, 32 within 24 hours, and 4 died to thoracic injury. These 4 patients were shock on arrival and died within 24 hours. The injury severity score, which was under 30 in 78.3% of patients, correlated to the mortality rate. Rib fracture was the most common thoracic injury in 96 patients followed by hemothorax in 91, pulmonary contusion in 79, and pneumothorax in 64. Most of the thoracic injuries were treated conservatively. Thoracotomy was performed in 6 patients. Other than one patient with rupture of the left pulmonary vein, 5 patients recovered. Continued bleeding at a rate of more than 200 ml/h from the chest drainage tube or no recovery from shock and large air leakage preventing re-expansion of the lung are indications for emergency thoracotomy. Thoracotomy should also be considered after conservative treatment in patients with continued air leakage or intrabronchial bleeding negatively affecting respiration. Indications for thoracotomy should be determined individually based on evaluating of vital sign.

[Shoulder metastasis as the initial manifestation of hepatocellular carcinoma (HCC)].

BACKGROUND: Primary diagnosis of hepatocellular carcinoma (HCC) by a shoulder metastasis is a rare event. HISTORY AND CLINICAL FINDINGS: A 68-year-old man was admitted with swelling of his left shoulder. No further clinical symptoms. Alcohol consumption: 1 l beer/day. On ultrasound, the clinically impressing tumor of the left shoulder showed calcifications. INVESTIGATIONS: Histologic examination of the tumor of the shoulder showed a well-differentiated, trabecular carcinoma consistent with the metastasis of an HCC. Subsequent ultrasound of the abdomen gave evidence of liver cirrhosis. In addition, an infiltrating mass was found, which encompassed 75% of the right liver lobe and was subsequently shown by histology to be a well-differentiated HCC with identical features of the tumor of the shoulder. Further metastases with pathologic rib fractures were found on CT scan of the thorax. DIAGNOSIS: Based on clinical findings, laboratory investigations and imaging studies, the patient suffered from an HCC owing to ethyl-toxic liver cirrhosis stage Child C, and initially presented with a shoulder metastasis. THERAPY: Due to the advanced tumor stage, no curative or palliative therapy was administered. CONCLUSION: This is an interesting case of an atypical primary diagnosis of HCC. The most important information was given by the pathologists who raised the suspicion of a metastasizing HCC by examining the tumor of the shoulder.

[Invasive techniques in emergency medicine. II. Preclinical thorax drainage--indications and technique].

The preclinical tension pneumothorax which even without technical support is easily recognizable, requires immediate decompression. However, there are a number of patients with thoracic injuries such as serial rib fractures or palpable skin emphysema which--in combination with a ventilator--may necessitate the insertion of a thoracic tube. In the preclinical setting this procedure usually only takes place in the ventilated patient. With patients who are respiratorily compensated and are breathing spontaneously, careful control and a conservative approach is advised even if pneumothorax is suspected.

[Fatal outcome after multiple trauma. The thoracic injury as the decisive factor].

In patients suffering from multiple injury, chest trauma is often the main cause of fatality. A case report is given and the literature reviewed.A 49 years old motorcyclist hit a car frontally in a road accident. After primary stabilization and first clinical care, he was transferred to our trauma centre because of severe chest injury, suspected pericardial effusion and lesion of the thoracic aorta. Initial diagnostics (plain radiographs, CT scan of thorax, abdominal ultrasound, echocardiography) showed left-sided serial rib fractures, a fracture of the left scapula, a hematopneumothorax left-sided, bilateral lung contusion, a small pneumothorax of the right side, a minimal pericardial effusion and a small splenic hematoma. The patient was treated in the intensive care unit, and the situation was initially stable. After 12 h, respiration deteriorated and a bronchoscopy showed filling of the airways with mucous fluid. The CT scan showed a worsening of the pulmonary damage and increasing pericardial fluid compression. A pericardiotomy was carried out, but the situation remained unstable. The patient was treated with invasive ventilation (PEEP>10, FiO2>0,5). Sudden severe bleeding out of left lower lobe was managed by thoracotomy and lobectomy. The patient remained unstable and died 95 h after the accident. This case shows that the severity of chest trauma does not necessarily correlate with the initial clinical and radiological findings. Even with all diagnostic and therapeutic procedures, a fatal outcome could not be prevented. This demonstrates the role of chest injury as a major and unforeseeable cause of death in multiple trauma patients.

[Child abuse].

Child abuse is most often diagnosed by an emergency doctor on call who sometimes "feels" more than knows what he is confronted with. He should nevertheless always take a medical history and make a physical and radiological examination. X-ray imaging and an ophthalmologic retinal examination are the most important diagnostic steps. Typical findings are multiple and/or dorsal rib fractures, complex skull fractures, physeal fractures, all fractures within the first 12 months, multiple fractures in different localisations and stages of healing, all injuries with uncommon distributions, all patterned bruises, immersion burns, intramural hematoma and every unexplained loss of consciousness. The first step towards victim protection is always the removal of the abused child from its caregivers by admitting it to hospital, as 95% of all cases of reported child abuse take place within the child's family.

[Tension pneumopericardium--a rare complication in multiply injured patients].

Thoracic injury is a relevant and common complication in multiply injured patients. Typical patterns of injury comprise rib fractures, serious lung trauma as well as diaphragmatic and aortic rupture. In contrast, posttraumatic tension pneumopericardium following blunt thoracic trauma is a very rare complication. However, if unrecognized it might provoke cardiac tamponade and death. For the development of a pneumopericardium, free air follows the vessel bundles up to the pericardium. Hence, if the number of ruptured alveoli is high, or these alveoli are placed close to the heart, and if additional risk factors, such as high inspiratory ventilation pressure, are present, a tension pneumopericardium can induce cardiac tamponade. The aim of this report is to illuminate diagnostic and therapeutic strategies for posttraumatic pneumopericardium by presentation of a case from our trauma centre and a critical discussion of the present literature.

[Chest injury. Part II: Management of specific injuries].

Significant injuries to the thorax comprise pneumothorax, rib fractures, lung contusion, cardiac contusion, aortic laceration, ruptured diaphragm, and the very rare injuries to the tracheo-bronchial tree and the esophagus. A surgeon dealing with chest trauma patients needs to be familiar with the indications for and execution of chest tube insertion for thoracic drainage, pericardial puncture, and thoracoscopy and thoracotomy. Interventional techniques are gaining increasing acceptance in the management of major vascular injuries. The vast majority of patients with chest injury do not need an operative intervention, but it is necessary to place a thoracic drain in 10-15% of cases or to perform in a much lower proportion a pericardial puncture or a thoracotomy.

[Thoracic trauma].

Blunt chest trauma is the leading cause of thoracic injuries in Germany, penetrating chest injuries are rare. Hereby, single or multiple rib fractures, hemato-pneumothorax and pulmonary contusion represent the most common injuries. The early management of thoracic injuries consists of detection and sufficient therapy of acute life threatening situations like tension pneumothorax, acute respiratory insufficiency or severe intrathoracic bleeding. Most of the isolated thoracic injuries are adequately treated by conservative means, sufficient analgesia, drainage of intrapleural air or blood, physiotherapy and clearance of bronchial secretions provided; operative intervention is rarely indicated. In multiple injured patients however, severe blunt chest trauma and especially pulmonary contusion negatively affects outcome with a significant increase of morbidity and mortality. Hence, patients with this combination of pulmonary injuries, such as lung contusion and associated severe injuries, carry a particular high risk of respiratory failure, ARDS and MOF with a considerable mortality. Therefore, early exact diagnosis of all thoracic injuries is essential and can be achieved by thoracic computed tomography, which becomes more and more popular in this setting. Early intubation and PEEP-ventilation, alternate prone and supine positioning of multiple injured patients with lung contusion and differentiated concepts of volume- and catecholamine therapy represent the basic therapeutic principles. Additionally, the entire early trauma management of multiple injured patients must focus on the presence of pulmonary contusion. Every additional burden on their pulmonary microvascular system like microembolisation during femoral nailing, the trauma burden of extended surgery or mediator release in septic states may cause rapid decompensation and organ failure and therefore, has to be avoided.

Constant flow insufflation of oxygen as the sole mode of ventilation during out-of-hospital cardiac arrest.

BACKGROUND: Constant flow insufflation of oxygen (CFIO) through a Boussignac multichannel endotracheal tube has been reported to be an efficient ventilatory method during chest massage for cardiac arrest. METHODS: Patients resuscitated for out-of-hospital cardiac arrest were randomly assigned to standard endotracheal intubation and mechanical ventilation (MV; n =457) or use of CFIO at a flow rate of 15 l/min (n=487). Continuous chest compressions were similar in the two groups. Pulse oximetry level was recorded every 5[Symbol: see text]min. Outcome of initial resuscitation, hospital admission, complications, and discharge from the intensive care unit (ICU) were analyzed. The randomization scheme was changed during the study, but the in-depth analysis was performed only on the first cohort of 341 patients with CFIO and 355 with MV, because of randomization problems in the second part. RESULTS: No difference in outcome was noted regarding return to spontaneous circulation (CFIO 21%, MV 20%), hospital admission (CFIO 17%, MV 16%), or ICU discharge (CFIO 2.4%, MV 2.3%). The level of detectable pulse saturation and the proportion of patients with saturation above 70% were higher with CFIO. Ten patients with MV but only one with CFIO had rib fractures. CONCLUSIONS: CFIO is a simplified alternative to MV, with favorable effects regarding oxygenation and fewer complications, as observed in this group of patients with desperate prognosis.

Imaging characteristics of hemophagocytic lymphohistiocytosis.

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a nonmalignant disorder of immune regulation, with overproduction of cytokines and diminished immune surveillance. Symptoms are nonspecific and may affect multiple organs, including the central nervous system. Neuroimaging findings have been described in case reports and small series; body imaging findings have not been described extensively. OBJECTIVE. To summarize findings of the most frequently performed imaging studies of the brain, chest and abdomen in patients with HLH. MATERIALS AND METHODS: Retrospective review of chest radiographs and CT, abdominal ultrasound and CT, brain CT and MRI, skeletal surveys, and autopsy data. RESULTS: Twenty-five patients were diagnosed and treated for HLH at our institution over an 11-year period; 15 patients (60%) died. Common chest radiograph findings included alveolar-interstitial opacities with pleural effusions, often with rapid evolution and resolution. Hepatosplenomegaly, gallbladder wall thickening, hyperechoic kidneys and ascites were common abdominal findings, which resolved after therapy in some cases. Brain-imaging studies revealed nonspecific periventricular white-matter abnormalities, brain-volume loss and enlargement of extra-axial fluid spaces. Three infant cases, one with intracranial hemorrhage, one with multiple pathologic rib fractures and one with diaphyseal periosteal reaction involving multiple long bones on skeletal survey, raised suspicion of child abuse at presentation. Abuse was not substantiated in any case. CONCLUSIONS: Clinicians and radiologists should be aware of the radiographic manifestations of HLH, which are nonspecific and overlap with infectious, inflammatory and neoplastic disorders. Findings in the chest (similar to acute respiratory distress syndrome) and abdomen may progress rapidly and then regress with institution of appropriate anti-HLH therapy. CNS findings may be progressive. In some infants, initial imaging findings may mimic nonaccidental trauma.

67Ga-SPECT/CT with a hybrid system in the clinical management of lymphoma.

PURPOSE: The purpose of this study was to investigate the added value of co-registered fusion imaging using a hybrid system in patients with lymphoma. METHODS: Twenty-four lymphoma patients underwent (67)Ga-SPECT/CT using a hybrid tomograph consisting of a dual-head, variable-angle gamma camera and a low-dose X-ray tube. Results were compared with those of SPECT alone. RESULTS: Forty-five lesions were identified by SPECT alone, while 49 were detected by SPECT/CT. Forty out of the 45 lesions observed on SPECT were confirmed as lymphoma, but five were due to other causes (thoracic aorta blood pool activity, sialoadenitis in the submandibular gland, bowel activity, rib fracture and bone marrow activation due to radiotherapy). SPECT/CT identified nine more neoplastic lesions compared with SPECT alone: four areas of radiopharmaceutical accumulation were observed in para-aortic lymph nodes, three in the spleen, one in the liver and one in para-iliac lymph nodes. In five cases, SPECT/CT provided additional anatomical information over SPECT alone. In four patients, four large areas of (67)Ga uptake (one mediastinal, two supraclavicular and one para-aortic) were better characterised; in one subject uptake was localised in the seventh thoracic vertebra only by SPECT/CT. Hybrid imaging provided additional data in 13 patients (54.2%), thus inducing oncologists to reconsider the therapeutic approach in eight subjects (33.2%): unnecessary treatment was avoided in four (16.6%) while therapy was altered in another four (16.6%). CONCLUSION: SPECT/CT hybrid system is able to provide information not obtained by SPECT alone. It allows the anatomical localisation of lymphoma and physiological radiopharmaceutical uptake, facilitates the diagnosis of tumours located in the abdomen (subdiaphragmatic lesions) and provides information that may cause a change in therapeutic strategy.
