Purulent pericarditis is rapidly fatal if untreated [1,2]. With increased development of bacterial resistance to antibiotics, severe bacterial infections in children are becoming more frequent [3,4]. We report two children with purulent pericarditis who presented in a 1-month period for evaluation of acute abdominal distention and signs of sepsis. In both, one evaluated with computed tomography (CT) and one with ultrasound, abdominal findings included periportal edema, gallbladder wall thickening, and ascites secondary to right heart failure from cardiac tamponade. Radiologists should be aware that children with purulent pericarditis may have a normal heart size on radiographs, present with acute abdominal symptoms, and demonstrate findings of right sided heart failure on abdominal imaging.

When systemic oxygen delivery (DO2) is reduced, oxygen consumption (VO2) is maintained until a critical level is reached (DO2crit). Sepsis is thought to shift DO2crit to the right and lengthen the supply-dependent portion. We tested the effect of interleukin (IL)-1beta, which is one of the key cytokines related to sepsis, on the DO2-VO2 relationship. Fifteen rabbits were subjected to stepwise cardiac tamponade to reduce DO2 to 10% by inflating a handmade balloon placed into the pericardial sac. Seven rabbits were given 10 microg/kg of IL-1beta intravenously (IL-1beta group) prior to the graded cardiac tamponade. The remainder received saline alone (control group). The DO2-VO2 relationship was analyzed by the dual-line method. IL-1beta significantly decreased mean arterial pressure (65 +/- 11 mmHg from baseline 85 +/- 7 mmHg) without altering cardiac output. The IL-1beta group showed significantly steeper supply-independent line slopes than did the control group (0.19 +/- 0.02 vs. 0.11 +/- 0.02, respectively), which resulted in a DO2crit shift to the left (IL-1beta group, 8.7 +/- 1.7 ml/kg x min vs. control, 11.7 +/- 0.7 ml/kg x min). The IL-1beta group also showed greater PO2 and plasma lactate levels in the portal vein than did the control group. These results indicate that IL-1beta impairs systemic oxygen uptake even before VO2 becomes supply-dependent, presumably due to maldistribution of the blood flow including the splanchnic circulation.

The clinical and laboratory findings of eight (20%) cases of cardiac involvement of 39 patients with sepsis caused by S. aureus (Staphylococcus aureus) were reviewed retrospectively. Our purpose was to emphasize the importance of the cardiac findings in patients with sepsis caused by S. aureus in childhood. The ages of the patients ranged from 6 to 14 years. All patients had pericardial effusion which was confirmed by echocardiographic (ECHO) examination in all cases except the one in whom ECHO examination could not be performed because he died 2.5 days after admission to the hospital. This patient also had myocarditis and heart failure. Aside from these, mitral insufficiency was diagnosed in the other patient; it was accepted as a sequela of rheumatic fever acquired previously. Open pericardial drainage was conducted successfully in the case who had a progression to cardiac tamponade. In the other patients pericardial effusion completely resolved with supportive and antibiotic therapy one to two weeks. Two of eight patients died from sepsis and septic shock; the mortality rate was 25%. Our findings show that cardiac involvement was fairly high (20%) in S. aureus sepsis in childhood. Therefore, it is suggested that children with S. aureus sepsis should be carefully monitored for cardiac involvement.

We present here a patient with acute myeloid leukemia (M2) who developed fatal infective endocarditis. On admission, the patient (67-year-old male) had mitral stenosis and atrial fibrillation. Complete remission was achieved after induction chemotherapy. During the course of consolidation therapy, he developed sepsis caused by coagulase-negative staphylococcus, which was successfully treated with antibiotics. Thereafter, blood culture yielded multidrug-resistant staphylococcus epidermidis. An echocardiogram revealed mitral valve regurgitation with vegetation. He was diagnosed as having infectious endocarditis. In spite of prolonged antibiotic therapy, destruction of the mitral valve progressed, and the patient underwent valve replacement therapy. He died of cardiac tamponade 5 days after the surgery.

The development of renal failure after open heart surgery is associated with a high mortality. Thirteen patients were treated with continuous hemodiafiltration (CHDF) for renal failure following open heart surgery since April 1999 to December 2001. The indication of CHDF was blood purification in 8 patients and water balance control in 5 patients. Two patients with hemodialysis (HD) before operation returned to usual HD early after operation, and discharged. One patient died of severe heart failure, and another patient died of sepsis and multi organ failure. In these 2 patients, CHDF could not withdrawn. Seven patients weaned from CHDF 1 to 19 days after operation. Five of 7 patients discharged, but 2 patients died of cerebral infarction 4 month after operation. The remaining 2 patients could not wean from CHDF, and were introduced HD. Only 1 of 13 patients had bleeding tendency (cardiac tamponade). CHDF did not influence the hemodynamic state and was very effective for the treatment of renal failure in many patients.

We describe the case of a 64-year-old patient admitted to our hospital because of syncope and suspicion of cardiac tamponade. At admission he had temporary alteration of conscience with clinical evidence of sepsis without chest pain. There was a mild pericardial effusion in absence of clinical and echocardiographic signs of cardiac tamponade. About 36 hours later we found evidence of an aortic dissection and in the blood culture an isolation of Clostridium fallax that we consider the probable cause of this lesion.

A 34-year-old female with end-stage renal disease was admitted for severe metabolic acidosis, uremic encephalopathy, pericarditis and severe anemia following a bout of acute gastroenteritis. She improved on aggressive medical management including intensive hemodialysis and was initiated onto maintenance heparin-free hemodialysis (twelve hours per week) and discharged. After a week, she presented with fever with chills and rigors for three days, was toxic, severely orthopenic and had a pulsus paradoxus of 36 mmHg. Echocardiography suggested cardiac tamponade. Aspiration revealed frank pus with polymorphonuclear predominance and Staphylococcus aureus on culture. CT of the thorax revealed pericardial effusion. In the absence of any obvious septic foci, concomitant pleuro-pulmonary sepsis, mediastinal or intra-abdominal pathology; a diagnosis of "acute primary purulent pericarditis" was made. Patient was put on parenteral antibiotics-ceftriaxone and metrogyl. Vancomycin was added after sensitivity results. Pericardial drainage was required initially. After toxemia improved, paradox decreased and fever subsided, the pericardial catheter was removed and antibiotics continued for a period of four weeks. Maintenance hemodialysis was continued during hospital stay and after discharge.

Lymphoblastic lymphoma, an aggressive mediastinal mass, is recognized as serious threat to the patient in developing cardiac tamponade or airway obstruction. Surgical procedure is often required to relieve clinical emergency and to establish prompt pathological diagnosis. However, in such a patient, acute respiratory occlusion in the spine position can be a life-threatening complication during general anesthesia. We describe a 17-year-old man whose cardiac tamponade was treated by pericardial-pleural window through a left anterior thoracotomy in the lateral position. The patient recovered from hemodynamic compromise without showing respiratory occlusion during general anesthesia and remained in the lateral position until extubation. Pathological diagnosis was precursor T-lymphoblastic lymphoma. There were no complications attributable to the operative procedure. Further chemotherapy reduced the mediastinal mass in size after two weeks when the patient developed sepsis and died. Lateral position prevents respiratory occlusion during surgical procedure under general anesthesia in the patient of huge anterior mediastinal tumor with airway obstruction.

The purpose of this study was to review our experience with a mass casualty incident resulting from a boiler room steam explosion aboard a cruise ship. Experience with major, moderate, and minor burns, steam inhalation, mass casualty response systems, and psychological sequelae will be discussed. Fifteen cruise ship employees were brought to the burn center after a boiler room explosion on a cruise ship. Eleven were triaged to the trauma resuscitation area and four to the surgical emergency room. Seven patients were intubated for respiratory distress or airway protection. Six patients had >80 per cent burns with steam inhalation, and all of these died. One of the 6 patients had 99 per cent burns with steam inhalation and died after withdrawal of support within the first several hours. All patients with major burns required escharotomy on arrival to trauma resuscitation. One patient died in the operating room, despite decompression by laparotomy for abdominal compartment syndrome and pericardiotomy via thoracotomy for cardiac tamponade. Four patients required crystalloid, 20,000 mls/m2-27,000 ml/m2 body surface area (BSA) in the first 48 hours to maintain blood pressure and urine output. Three of these four patients subsequently developed abdominal compartment syndrome and died in the first few days. The fourth patient of this group died after 26 days due to sepsis. Five patients had 13-20 per cent bums and four patients had less than 10 per cent burns. Two of the patients with 20 per cent burns developed edema of the vocal cords with mild hoarseness. They improved and recovered without intubation. The facility was prepared for the mass casualty event; having just completed a mass casualty drill several days earlier. Twenty-six beds were made available in 50 minutes for anticipated casualties. Fifteen physicians reported immediately to the trauma resuscitation area to assist in initial stabilization. The event occurred at shift change; thus, adequate support personnel were instantaneously to hand. Our mass casualty preparation proved useful in managing this event. Most of the patients who survived showed signs of post-traumatic stress syndrome, which was diagnosed and treated by the burn center psychology team. Despite our efforts at treating large burns (>80%) with steam inhalation, mortality was 100 per cent. Fluid requirements far exceeded those predicted by the Parkland (Baxter) formula. Abdominal compartment syndrome proved to be a significant complication of this fluid resuscitation. A coordinated effort by the facility and preparation for mass casualty events are needed to respond to such events.
