Granulocyte transfusions are increasingly being used as therapy for newborns with sepsis and neutropenia. We injected either group B Streptococcus or phosphate-buffered saline solution intraperitoneally into adult and newborn rats. Human granulocytes, labeled with chromium 51, were transfused seven hours later. When the newborn rats were killed 13 to 19 hours after injection, they had 10(2) to 10(6) cfu/gm Streptococcus organisms in both lung and brain. Only one third of the adult rats had 10(2) to 10(4) cfu/gm Streptococcus organisms in either lung or brain. A greater proportion of the transfused granulocytes was present in lung and brain tissue of newborn rats, compared with adult rats (p less than 0.05), irrespective of infection. Granulocyte transfusion did not change the peripheral blood leukocyte count in adult rats but increased the count in newborn rats (p less than 0.05). The immature myeloid pool in the bone marrow of adult rats increased significantly with either infection or transfusion (p less than 0.01). The immature pool in newborn rats increased significantly only with infection (p greater than 0.001), although the combination of infection and transfusion also had a significant effect on the pool (p less than 0.01). Infection and both infection and transfusion, but not transfusion alone, significantly affected the mature myeloid bone marrow pool in adult and newborn rats (p less than 0.001). The depletion of the mature myeloid elements of the bone marrow in response to infection was dramatic in neonatal rats, compared with that in adult rats. Both transfused granulocytes and hematogenously spread streptococci lodge in the brains and lungs of neonatal rats more effectively than in those of adult rats.

A twelve year prospective wound audit was undertaken in an academic surgical unit. Data from 10,000 operations were analysed. Overall, wound infection rates decreased during this time. Infection rates in contaminated wounds in particular fell from 19.2% to 4.7%. This decrease in wound infection may be related in part to a change in the antibiotic prophylactic regimen and in part to the institution of the wound sepsis audit which provided regular information on the unit infection rates. This audit permitted early detection of adverse trends, and may have had a direct influence on surgical techniques.

Infection continues to be the number one cause of morbidity in terms of complications for the renal transplant patient. Overwhelming infection may lead to hypoxemia, sepsis, and cardiovascular instability, which necessitate intensive care nursing for the patient. Although the care may be similar to that of other patients with these pathophysiologic processes, the transplant patient has the added complication of iatrogenic immunosuppression. On the other hand, immunosuppressive therapy may be discontinued, if necessary, in order to save the patient's life. Therefore, if the renal transplant patient needs to be treated in the intensive care unit, it is primarily important for the nurse to monitor for signs and symptoms of the infections.

Infection is a generally feared complication of liquor drainage. Shunt sepsis is reported in this paper with reference to 284 patients with liquor drainage. The rate of infection amounted to 9.1 percent. Therapeutic action included application of antibiotics, surgical valve removal, and delayed restitution. The mortality was as high as 29.4 percent. Chemoprophylaxis should begin in parallel with primary shunt implantation.

To focus attention on the problem of infant mortality in Lebanon, data were compiled on infant mortality from 1978 to 1986 at the American University of Beirut Medical Center. Causes of death are analyzed for 602 males and 398 females. 54.9% deaths occurred at 1 month of age and 77.4% died within the 1st year. Autopsies were performed on .7%. 37.7% of all neonatal deaths were due to neonatal diseases such as hyaline membrane disease, asphyxia neonatorum, immaturity, necrotizing enterocolitis, hemorrhage, hemolysis, meconium aspiration, and kernicterus. Better prenatal care would reduce this group, or the administration of corticosteroids to the mother 24-48 hours prior to delivery, as well as rapid resuscitation at birth and prevention of the 5 curses: hypoxemia, hypoglycemia, hypothermia, hypotension, and acidosis. Although unavailable in Lebanon, administration of surfactants through an endotracheal tube would also help. Infections constitute 25.1% of deaths; many are preventable through adequate public health measures and strict personal hygiene, i.e., diseases such as sepsis, pneumonia, meningitis, gastroenteritis, hepatitis, encephalitis, and 1-2 cases of the following: diphtheria, measles, peritonitis, tetanus, tuberculosis, cytomegalis inclusion, herpes, parathyphoid, pertussis, poliomyelitis, and shigellosis. Congenital diseases were 21.6%. In utero diagnosis could prevent some diseases and in utero treatment is possible for hydrocephalus and hydronephrosis. Screening programs postnatally could lead to treatment. 5.9% were malignancies such as leukemia, lymphoma, brain tumors, histocytosis, Wilm's tumor, Ewing sarcoma, and Hodgkin's disease. Early diagnosis is critical if mortality is to be reduced in this group, but medical advances are still needed. 2.9% are miscellaneous diseases such as poisoning, rheumatic diseases, marasmus, Reye's syndrome, nephrosis, rickets, and epilepsy. Most of these diseases are preventable, except for rheumatic inflammation of the heart. Recommended necessary steps to reduce infant mortality are: prenatal care, diagnosis and screening, intrauterine surgery; resuscitation and intensive care centers with modern equipment and trained personnel; national vaccination and screening programs; adequate public health measures and hygiene; parental education; and well-equipped hospitals to serve all regardless of income level.

Gynaecological infections range from vaginitis to septic shock. Postoperative infections are common sequelae of hysterectomy. Sexually transmitted infections start as vaginitis or rather as cervicitis. During pregnancy and delivery we find septic abortion, amnionitis, endometritis, wound infections, thrombophlebitis, sepsis, mastitis and urinary tract infections. In most infections cephalosporins are drugs of first choice because of their broad spectrum, their beta-lactamase stability and their lack of toxicity, which is especially important in pregnancy.

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.

Splenectomized subjects show a higher incidence of myocardial ischemia and of Overwhelming Post-Splenectomy Infection (OPSI). It is doubtful that implanted splenic tissue guarantees an adequate protection from OPSI. The histological characteristics and the capacity of protection from OPSI of two models of omental autoimplantation of splenic tissue in rats were examined. The implanted splenic tissue offers a significant protection from pneumococcal sepsis, even though there is no relation between implant architecture and survival rate.

Between October 1985 and March 1988, 16 patients received the Jarvik-7 total artificial heart as an interim device before transplantation. Ten patients were afflicted with cardiomyopathy, and 6 had end-stage ischemic disease. All but 1 were men; the mean age was 47 years (range, 27 to 59 years). Thirteen patients developed cardiogenic shock despite the use of intravenous inotropic agents (mean, 23 days; range, two to 83 days) and the intraaortic balloon pump (mean, 13 days; range, two to 65 days). Three other patients became candidates because of failed transplantation. The 100-mL Jarvik-7 device was used in the first 3 patients; all subsequent recipients were treated with the 70-mL Jarvik-7. Postoperative anticoagulation was designed to keep the partial thromboplastin time between 2 and 2.5 times control. The control values were obtained during administration of heparin and dipyridamole. In all cases the function of the total artificial heart was adequate to support the needs of the recipient, and there were no mechanical difficulties with the device or the drive system. The average time of implantation was 9 days (range, one to 35 days). Two patients died before transplantation, 1 with sepsis from fungus and the other with hemorrhage from a torn pulmonary arterial anastomosis. Fourteen patients received cardiac allografts, and 7 continue to survive without restrictions. Infection within the mediastinum caused the death of 4 patients after transplantation; in 3 of these mediastinitis was not recognized before transplantation but occurred within the first 2 weeks after transplantation.(ABSTRACT TRUNCATED AT 250 WORDS)
