Patients treated with chronic dialysis have a high risk of acquiring viral infections and blood transfusions are commonly considered to be the vehicle of transmission. In Brazil this source is implicated in infection of 15 percent of patients developing acquired immunodeficiency syndrome (AIDS). So, we evaluated the relative risk of our patients in dialysis becoming infected with human immunodeficiency virus (HIV), the virus associated with the AIDS. An enzyme immunoassay showed 6 of 104 patients on dialysis to have antibodies to HIV. In five infection with HIV was confirmed by Western blot tests. Investigation of other risk factors for AIDS showed that blood transfusion was the most likely cause of contamination. There was no correlation between HIV and HBV infections. Only one patient had leucopenia and low OKT4/T8 ratio and she died 90 days after sorologic diagnosis of HIV infection; the cause of death was encephalopathy and sepsis. Two patients died after 4 and 16 months victims of cardiocirculatory problems (non-AIDS related causes). Three patients remain asymptomatic on chronic hemodialysis 20, 36 and 37 months after diagnosis of HIV infection.

Recent improvements in the results of orthotopic liver transplantation (OLT) have made this a well-accepted treatment for patients with severe hepatic failure. Current problems encountered following OLT are discussed. Immediate complications comprise surgical bleeding, primary graft non-function, and graft failure due to hepatic artery occlusion. Secondary complications are frequent. Surgical ones include biliary and vascular (hepatic artery thrombosis most often) problems, as well as intra-abdominal abscesses associated with gastrointestinal perforation, biliary leak, graft ischaemia or an infected haematoma. 40% of patients having undergone OLT will be reoperated on, 2/3 of them within 3 months. Non-surgical complications are mostly pulmonary. The risk of pneumonitis is increased by prolonged mechanical ventilation; it is always potentially disastrous in the immunosuppressed, transplanted patient. Hypertension is also often seen in the early postoperative period; it requires prompt treatment. Early renal impairment after OLT is common, and of better prognosis than late onset renal failure, which is generally associated with shock, graft failure, sepsis or use of nephrotoxic agents. Seizures, usually only one, occur in about 10% of patients; recovery is complete. Encephalopathy with intracranial oedema related to fulminant hepatitis has a worse prognosis, but survival figures are quite encouraging. Three type of rejection are described after OLT: 1) severe accelerated rejection (very rare), 2) acute rejection encountered in about 70% of patients over the first 3 months, and 3) late rejection, which can lead to the vanishing bile duct syndrome (VBDS). Diagnosis of rejection is made by liver biopsy. Prophylactic immunosuppression includes cyclosporin, methylprednisolone and azathioprine. Cyclosporin toxicity and drug interactions are reviewed. Treatment of acute rejection episodes comprises an initial bolus of high doses of corticoid drugs; if there is no response, antilymphocyte globulin or monoclonal antibodies may have to be used. Infection is the main cause of death following OLT. Early infections, mostly intra-abdominal and pulmonary, are bacterial or fungal. Vital (especially CMV) and other opportunistic infections occur generally after the second week. Retransplantation, carried out in 10 to 25% of patients, may be urgent in case of primary graft failure, or hepatic artery thrombosis associated with graft failure, or hepatic artery thrombosis associated with graft failure. Other indications are early graft rejection with severe hepatic dysfunction, chronic rejection with severe VBDS, and recurrence of the initial disease.

The authors report the cases of five previously well children, aged 8 to 33 months, who were seen over a 14-year period, with admission temperatures in excess of 42.0 degrees C (107.6 degrees F). Four of the patients died. Each child had a similar clinical illness in which the hyperpyrexia played a critical role. Negative blood, cerebrospinal fluid, and stool cultures excluded bacterial sepsis as a possible etiology. This illness is similar, if not identical, to the newly described syndrome of hemorrhagic shock and encephalopathy (HSES) reported in European and American infants.

We reviewed 2,107 consecutive autopsies with neuropathologic examination at the Medical Center Hospital of Vermont, and identified 92 cases with significant pathologic evidence for infection involving the central nervous system (CNS). Of these, 35 took the form of multiple microabscesses. There were 19 men and 16 women, mean age 56. All patients were chronically ill, usually with an associated impaired immunity. The lung was the most frequent site of primary infection, and sepsis was often present. The most commonly identified causative organisms were Staphylococcus aureus and Candida albicans. Patients with CNS microabscesses developed a progressive encephalopathy associated with waxing and waning signs and symptoms. Laboratory and neuroradiologic studies were not helpful in elucidating the problem. We conclude that multiple microabscesses are a frequent, usually unrecognized, manifestation of CNS infection, and should be considered in the differential diagnosis of encephalopathy in hospitalized patients with chronic disease, immunosuppression and sepsis.

To augment the antitumor effect of high-dose melphalan and determine pharmacokinetics we conducted a phase I trial of escalating doses of high-dose IV melphalan with the chemosensitizer misonidazole for patients with advanced colorectal carcinoma. Fourteen patients with modified Dukes D adenocarcinoma of the colorectum were treated with a single course of melphalan (40-60 mg/m2 i.v. bolus q.d. X 3 days) and misonidazole (1-3 g/m2 p.o. q.d. X 3 days) followed by autologous bone marrow transplantation. Toxicity consisted of severe myelosuppression, moderate nausea and vomiting, and mild mucositis and diarrhea. One patient developed unexplained renal tubular acidosis, and a diffuse encephalopathy occurred in another patient. Three patients died within the first 30 days after the start of treatment, two due to tumor progression and one due to sepsis and disseminated intravascular coagulation-induced intracerebral hemorrhage. Six of 14 patients achieved a partial response, and the median response duration was 4 months (range 3-10 months). Analysis of misonidazole serum concentrations showed similar pharmacokinetics to those previously reported, suggesting no significant drug interaction with intravenous melphalan. Mean peak serum concentrations ranged from 81.8 micrograms/ml to 115.2 micrograms/ml at the second and third misonidazole dose levels, which approximate those known to provide effective chemosensitization with melphalan in animal models. In this phase I study, we showed that maximally tolerated doses of intravenous melphalan can safely be combined with oral misonidazole. In view of the large volumes of oral misonidazole required at the highest dose level, subsequent studies to determine the maximally tolerated dose of misonidazole should employ the intravenous form.

Multiple systems organ failure in association with sepsis has a distressingly high mortality rate. The spectrum of neurologic deficits and their incidence in septic patients remains poorly characterized. However, sepsis-associated CNS dysfunction appears to be as important a harbinger of excess mortality as renal or pulmonary dysfunction in septic patients. Brain microabscesses, disordered amino acid metabolism, alterations in brain neurotransmitters, and reduced cerebral blood flow and oxygen utilization have all been proposed as potential etiologies of septic encephalopathy. Unfortunately, much remains to be elucidated regarding the presentation and pathophysiology of septic encephalopathy before consideration of what constitutes appropriate therapy is likely to be fruitful. The dietary manipulation of plasma and brain amino acid profiles and refinement of therapeutic objectives of cardiovascular support to improve regional organ blood flow are but two promising areas of current investigation. At the present time, however, meticulous supportive therapy, appropriate antibiotics, and surgical drainage of a septic focus, when possible, represent optimal therapy.

Extracorporeal membrane oxygenation (ECMO) is an approved therapy for some neonates who have respiratory failure that is due to hyaline membrane disease, meconium aspiration, persistent pulmonary hypertension, congenital diaphragmatic hernia, or sepsis. The major complication of this therapy is hemorrhage, with intracranial hemorrhage having the highest morbidity and mortality. Seizures, incisional bleeding and bleeding in the pleural space, hypoxic-ischemic encephalopathy, renal failure, and cardiovascular complications account for most of the other complications. Cranial sonography provides an ideal imaging modality for baseline evaluation and daily follow-up; however, computed tomography and magnetic resonance imaging, because of better sensitivity, are important for assessment after ECMO. The changes in intracranial blood flow related to ECMO can be noninvasively evaluated by Doppler ultrasound modalities.

One-hundred-six cases of acute pancreatitis have been prospectively studied in order to determine the characteristics of the complications that occur in severe acute pancreatitis (SAP). 19.81% of the patients developed SAP and 7.5% died. Chronic hepatitic disease was the only previous condition found with an increased frequency in SAP patients. We should point out that 90.5% of the patients developed more than one and 38% between 4 and 6 complications during their hospital stay. The most frequently occurring complication was encephalopathy (11.33%) followed by sepsis (8.49%), renal failure (8.49%) and respiratory failure (7.55%). The time of onset of each of the complications was quite variable, ranging from the first hospital day (shock) to the 29th (choledochal stenosis). The patients suffering shock and/or respiratory failure had a greater mortality rate.

With proper nursing care and procedures, small hospitals in rural areas of developing countries can provide good neonatal care and achieve perinatal mortality rates comparable to those found at teaching hospitals. The 1st ingredient of adequate neonatology is the establishment of proper regimens for feeding, observation, and resuscitation of newborns. Even in areas where the majority of births take place at home, good neonatal care is possible as long as local risk factors are identified, all newborns are screened for these factors, and at-risk infants are referred for treatment. Factors that place infants at risk include birthweight under 2 kg or above 4 kg, delivery before 34 weeks' gestation, respiratory distress, severe birth asphyxia or trauma, jaundice, prolonged rupture of the membranes, infant not sucking or febrile, convulsions, congenital malformations, and maternal disease. 4 areas require special knowledge on the part of health personnel: the asphyxiated infant, hypothermia, hypoglycemia, and neonatal sepsis. Health workers must be familiar with proper resuscitation techniques, especially avoidance of excessive suctioning of the pharynx, and be alert to signs of hypoxic ischemic encephalopathy. Premature, small, asphyxiated, and sick infants are at greatest risk of hypothermia, a condition that can be prevented by drying and wrapping newborns immediately. Providers should be alert to signs of hypoglycemia in infants of diabetic mothers, large-for-gestational-age babies, the low- birthweight infant, and sick babies. To prevent sudden infant deaths, all sick newborns should be treated for neonatal sepsis.

We have retrospectively evaluated 24 sepsis episodes caused by viridans streptococci in 23 neutropenic children during a 21 months period at the Pediatric Hematology Unit of St. Louis Hospital. The underlying malignancies included acute lymphoblastic leukemia, acute non lymphoblastic leukemia, aplastic anemia and solid tumor. In 17 children neutropenia, defined as a neutrophil count of less than 500 per cubic millimeter, was caused by cytotoxic chemotherapy. For 6 other children neutropenia was consequential to pretransplant treatment regimen for autologous bone marrow transplantation including cytotoxic chemotherapy and total body irradiation. All patients had a silicone rubber atrial catheter. In 9 patients sepsis was associated only with fever for less than 48 hours. In 5 other children fever was prolonged more than 72 hours in spite of specific antimicrobial therapy. No other organism was isolated. In 10 patients, however, the infectious syndrome was severe and the features included cardiac failure (7 patients), pneumonia (7 patients) resembling adult respiratory distress syndrome, encephalopathy (3 patients) without meningitis and proteinuria, 7 of these patients needed a management in a pediatric intensive care unit and 2 died in spite of adapted antibiotics. Streptococci were isolated in blood cultures in 23 children.
