Septic complications after cardiac catheterization and percutaneous transluminal coronary artery angioplasty are distinctly uncommon. However, we have recently treated nine patients with sepsis and life-threatening complications after cardiac catheterization alone or after catheterization and subsequent percutaneous transluminal coronary angioplasty. The common denominator in all patients was either repeat puncturing of the ipsilateral femoral artery or leaving the femoral artery sheath in for 1 to 5 days after the procedure. Two patients died as a direct result of their septic complications. One death occurred in a patient in whom bacterial endocarditis with congestive heart failure developed, and the other patient had a large retroperitoneal hematoma that became secondarily infected. Infected aneurysms that were successfully treated developed in three patients. Our study suggests that colonization of the needle tract by skin flora predisposes to septic complications if repeat arterial punctures are required or if a femoral artery sheath is left in place for more than 24 hours. Patients in whom sepsis develops after these procedures should be initially treated with antibiotics effective against gram-positive organisms. CT scanning or angiography should be considered for patients with persistent sepsis, septic emboli, and abdominal or flank pain. Infected aneurysms require resection or ligation because of the propensity of these aneurysms to rupture.

We have reviewed 116 cases of bacterial endocarditis treated surgically and 26 cases treated medically since 1973. There were 123 patients with native valve endocarditis and 19 patients with prosthetic valve endocarditis. Overall, the left-sided valves were infected most frequently. There were 10 cases with right-sided valves involved. Multiple valves were infected in 6 patients. There were 6 perioperative deaths in the surgical group. The most common cause of death was multi-organ failure associated with uncontrollable sepsis. The overall operative mortality for active endocarditis was 7.7% (4/55), and for healed endocarditis, 3.3% (2/61). For active native valve endocarditis, the mortality was 4.2% (2/48), for healed native valve endocarditis, 3.6% (2/55), for active prosthetic valve endocarditis, 28.6% (2/7), and for healed prosthetic valve endocarditis, 0%. There was no difference in the operative mortality between active native valve endocarditis and healed native valve endocarditis. The mortality of active prosthetic valve endocarditis was significantly higher than that of active native valve endocarditis (p less than 0.01). Of the 26 patients treated medically, 7 died during the initial hospitalization. The major factor related to mortality in the medically treated patients was persistent sepsis (four patients), and congestive heart failure (three patients). The overall mortality of the medical group for active valve endocarditis was 15% (3/20), and for active prosthetic valve endocarditis, 67% (4/6). We conclude that patients with infective endocarditis with significant valve lesions who are unresponsive to medical therapy should be considered for urgent surgery.

Forty-eight patients with acute renal failure (ARF) who were referred to the Department of Renal Medicine, Singapore General Hospital for acute dialysis between August 1985 and August 1989 were studied retrospectively to identify risk factors associated with ARF that serve as prognostic indicators. There was no difference in the mean age of survivors and non-survivors (49.5 +/- 17.5 years vs 53.5 +/- 18 years, p greater than 0.05). The overall mortality rate was 52%. ARF as a result of surgical complication had a higher mortality rate in comparison to ARF from medical complications (66% vs 50%, p greater than 0.05). Septicaemia was the most common cause of ARF requiring dialysis. Hepatobiliary sepsis was the most frequent cause of septicaemia. Pre-dialysis serum urea and creatinine levels, and the number of dialysis treatments did not affect the outcome. Poor prognostic indicators included oliguria or anuria, fluid overload and coma. Patients tended to have a worse outcome if they had more than three risk factors taken from the following list:-decreased renal perfusion, assisted ventilation, coma, gastrointestinal dysfunction, recent surgery, sepsis, congestive heart failure, hepatobiliary dysfunction, malignancy, diabetes mellitus, chronic renal insufficiency and poor nutritional status. Early referral of patients with septicaemia due in particular to hepatobiliary infection may improve the prognosis.

A female child with Weaver syndrome is described. She did not show the excessive growth characteristic of this syndrome until after adequate caloric intake was achieved by feeding through a gastric feeding tube. Her inadequate nutrition was a result of feeding difficulties during infancy. In addition, she had recurrent pulmonary infections, apneic spells, and severe developmental delay. She died at 16 months of sepsis, congestive heart failure, and respiratory arrest. The autopsy revealed marked atrophy of the brain and cardiac ventricular hypertrophy. Most of the brain changes were thought to be from hypoxia.

A 1-month-old boy without precedent clinical signs of heart disease died unexpectedly. At autopsy, the child was found to have origin of the right coronary artery from the left sinus of Valsalva immediately leftward to the thickening of the aortic wall at the cuspal commissure and adjacent to the ostium of the left main coronary artery. The association of this coronary anomaly with otherwise unexplained prenatal or early postnatal death has only recently been appreciated as a potential cause of sudden infant death and mimic of sepsis, dysrhythmias, congestive heart failure, or metabolic storage diseases.

To determine the magnitude, duration, and associated factors of perioperative changes in pulmonary function, we retrospectively reviewed the medical records of 145 patients who required preoperative mechanical ventilation for acute respiratory failure before undergoing 200 surgical procedures. Patients were grouped into five pulmonary diagnostic categories: (1) adult respiratory distress syndrome (ARDS) (n = 49); (2) pneumonia (n = 20); (3) atelectasis (n = 65); (4) congestive heart failure (n = 11); and (5) acute ventilatory failure (n = 55). Sixty patients underwent intra-abdominal surgery, 135 patients required surgery on the periphery, and five patients had a thoracotomy. For all patients, PaO2/FIO2 declined significantly from 321 mm Hg (mean) preoperatively to 258 mm Hg intraoperatively, and shunt fraction (Qs/QT) increased from 0.16 to 0.23 without a significant change in PaCO2. The magnitude of the increase in Qs/QT did not differ among pulmonary diagnostic groups. Preoperatively, patients undergoing laparotomy had lower PaO2/FIO2 (278 vs 340) and higher Qs/QT (0.19 vs 0.14) than patients requiring surgery on the periphery. Intraoperatively, Qs/QT increased more during abdominal procedures than during peripheral procedures. Intraoperative hypoxemia (PaO2/FIO2 less than 80 mm Hg) occurred during 13 procedures. Hypoxemic patients had a mean increase in Qs/QT of 0.20 (0.25 preoperatively to 0.45 intraoperatively), and a significant increase in PaCO2 from 38 mm Hg to 45 mm Hg intraoperatively). In general, these patients had ARDS (n = 10), sepsis (n = 10), a laparotomy (n = 9), and intraoperative mechanical ventilation via the Ohio Anesthesia ventilator (n = 8), a commonly used operating room ventilator. Their preoperative peak airway pressure (54 cm H2O) and minute ventilation (20 L/min) requirements exceeded the capabilities of the Ohio Anesthesia ventilator and likely contributed to impaired gas exchange intraoperatively. Within the first several hours postoperatively, PaO2/FIO2 recovered to preoperative levels in all patients, even in those who had severe intraoperative hypoxemia develop and who underwent laparotomy. We conclude that most patients with acute respiratory failure receiving preoperative mechanical ventilation experienced mild-to-moderate deterioration in intraoperative pulmonary oxygen exchange that rapidly returned to preoperative levels after surgery. We recommend that necessary surgery not be postponed by concern that pulmonary function will be worsened by surgery and anesthesia.

Mitoxantrone in combination with VP-16 proved to be effective in refractory and relapsed acute myeloid leukemia (AML), with 42% of patients achieving complete remission (CR). The aim of this study was to assess whether the addition of cytosine arabinoside increased the response rate at a tolerable toxicity. The regimen consisted of mitoxantrone (M) 10 mg/m2 i.v. days 4-8, cytosine arabinoside (A) 100 mg/m2 continuous infusion days 1-8, and etoposide (VP-16) (V) 100-120 mg/m2 i.v. days 4-8 (MAV protocol) for relapsed and refractory AML. Thirty-six patients were treated, with a median age of 51 (20-73) years. For induction therapy one to two MAV cycles and for consolidation therapy two courses were scheduled. Twenty-one (58.3%) patients attained a complete remission (CR), with a median duration of 4.5 (1-12+) months. The median survival of all patients was 5.5 (0.5-15.5+) months. Four patients died in CR from chronic infections or after consolidation therapy with MAV. In evaluable patients, times to greater than 500 granulocytes/microliters and greater than 25,000 platelets/microliters were 23 (7-46) and 23 (6-44) days, respectively. In 54 evaluable MAV courses the following toxicity was observed (WHO grades 3/4): 26%, nausea and vomiting: 9%, hemorrhage; 6%, bilirubinemia; 11%, diarrhea; 22%, mucositis; 6%, local infection; 20%, septicemia; 13%, fever of unknown origin; 2%, cardiac arrhythmia; 7%, congestive heart failure. We conclude that MAV therapy is a highly active antileukemic combination with acceptable toxicity, which is recommended for further clinical trials in untreated AML.

Five cases of bacteremic infections due to Haemophilus influenzae type f in adults are described, and previous reports of type f disease in nonpediatric patients are reviewed. Respiratory tract infections were most common in our series (two cases of pneumonia, one of epiglottitis, and one of nosocomial septicemia probably resulting from aspiration pneumonitis). All of these patients had factors predisposing them to respiratory tract infections, e.g., neurologic disease, congestive heart failure, or cigarette smoking. A fifth patient, who was bacteremic without an apparent primary focus, had dysgammaglobulinemia. Six episodes of bacteremia occurred in five patients; 11 of 13 cultures of blood obtained before parenteral antibiotic therapy were positive. All isolates were biotype I and susceptible to ampicillin. Antibiotic therapy was curative in cases of proved respiratory tract infection but failed in the setting of nosocomial septicemia, perhaps because of delayed initiation. The brevity of antibiotic treatment of the cryptogenic bacteremia permitted infection of a prosthetic vascular graft and recurrent bacteremia. Graft removal and repeated antibiotic therapy were curative.

Thirty-nine patients with adult respiratory distress syndrome (ARDS) were enrolled in a study to identify potential age-related changes in organ system function that may help explain the apparent association between age and poor outcome in these patients. Criteria for enrollment included an arterial PO2-to-inspired O2 concentration ratio less than or equal to 200 in a clinical setting consistent with ARDS. Patients were excluded if they were less than 18 yr old, had clinical manifestations of congestive heart failure, were seropositive for the human immunodeficiency virus, or had stage II metastatic lung cancer. Patients were divided into two groups: those less than 60 yr old (mean 42 +/- 3 yr, n = 17) and those greater than or equal to 60 yr old (73 +/- 2 yr, n = 16). A group of six patients was analyzed as a separate subset based on a body temperature less than or equal to 97.5 degrees F at enrollment (hypothermic patients, 73 +/- 4 yr old). Sepsis was present in 67% of the nonhypothermic patients and in all the hypothermic patients. Mortality rates were 12% in the patients less than 60 yr and 69% in the nonhypothermic patients greater than or equal to 60 yr. All the hypothermic patients died. Sequential data obtained over 6 days were compared within and between groups. The following results were obtained. 1) The ratio of arterial PO2 to inspired O2 fraction was greater and the positive end-expiratory pressure used was significantly less in the patients greater than or equal to 60 yr old compared with the younger group.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors reviewed the initial presentation of seven infants with acute myocarditis. All patients presented with respiratory distress including tachypnea (respiratory rate greater than or equal to 40) and intercostal retractions. Other findings included tachycardia (heart rate greater than or equal to 120) (7/7) and grunting (6/7). Lungs were clear to auscultation in six out of the seven patients. Cardiomegaly was seen in five of the initial chest roentgenograms. Each initial electrocardiogram had abnormal findings. Initial diagnoses were sepsis and shock in three patients, pneumonia and asthma in two, and congestive heart failure in two. Six patients required tracheal intubation. All required admission to the Pediatric Intensive Care Unit (ICU). Two patients died. Myocarditis should be suspected in a child presenting with severe respiratory distress, tachycardia, cardiomegaly, and/or an abnormal electrocardiogram. Prompt stabilization and admission to a pediatric intensive care unit for further evaluation and treatment is essential.
