In chronic granulomatous disease (CGD) enzyme-deficient neutrophils and mononuclear cells lack the respiratory burst required for biocidal activity. Recurrent infections lead to granulomas in various organs but brain lesions are rare. In the present case, a 23-year-old male with numerous infections since early childhood died of overwhelming pulmonary aspergillosis. He first began to experience neurological deficits at the age of 17. Computerized tomography and magnetic resonance imaging revealed fleeting white matter lesions that were interpreted as multiple sclerosis (MS). At post mortem, three types of brain lesions were found: (1) Pigmented macrophages in perivascular spaces and the leptomeninges similar to those reported previously. They contained fine, golden-brown, lipofuscin-like material whose chemical composition included a sulfur peak by X-ray analysis. (2) Focal, well-demarcated, "burnt out" white matter lesions with loss of both myelin and axons and intense sclerosis. (3) Diffuse areas of mild pallor in the centrum ovale which spared the U fibers. The pigmented macrophages are characteristic of those seen in the periphery in CGD. The origin of the discrete, destructive white matter lesions is unclear. They may have resulted from: (i) earlier activity by CGD macrophages; (ii) previous infections due to sepsis or embolism; or (iii) possibly post-infectious encephalomyelitis. The more diffuse, mild, white matter lesions are attributed to edema. Evidence for MS, progressive multifocal leukoencephalopathy, or human immunodeficiency virus encephalitis was lacking. This case is presented to alert us to look more carefully for brain lesions in CGD, characterize them and to help determine their cause.

Listeria monocytogenes can cause circling disease, encephalitis, meningitis, septicemia, and mastitis in dairy cattle. Shedding of the pathogen from the udder or contamination from the environment can lead to presence of L. monocytogenes in raw milk. Surveys indicate the pathogen is in about 4% of US raw milks. Although HTST pasteurization commonly inactivates L. monocytogenes, evidence suggests that under unusual circumstances minimal survival is possible. The pathogen grows well in liquid dairy products at 4 to 35 degrees C and achieves higher populations in chocolate than in unflavored milks. When present in cheese milk, growth of L. monocytogenes may be retarded but not stopped by lactic starter cultures. The pathogen is concentrated in the curd with only a small fraction of cells in milk appearing in whey. Once in curd, the behavior of the pathogen ranges from growth (feta cheese making) to death of most but not all cells (cottage cheese making). During ripening of cheese, the numbers of L. monocytogenes decrease gradually (as in Cheddar or Colby cheese), decrease precipitously early during ripening, and then stabilize (as in blue cheese) or increase markedly (as in Camembert cheese). Consumption of foods containing L. monocytogenes can lead to listeriosis in susceptible humans (adults with a compromised immune system), pregnant women, and infants). In large outbreaks of human listeriosis, mortality rates of ca. 30% are common.

Six cats (Nos. 1-6) were inoculated intramuscularly with (1 x 10(6)) and orally (5 x 10(5)) tachyzoites of Neospora caninum. Three (Nos. 1-3) of the six cats were given 40 mg/kg methylprednisolone acetate 7 days before and on the day of inoculation with N. caninum tachyzoites, and three cats (Nos. 4-6) were not given methylprednisolone acetate. Two of the cats (cat Nos. 1 and 2) given methylprednisolone acetate died suddenly. Cat No. 1 died 8 days post-inoculation, and cat No. 2 died 16 days post-inoculation. Cat No. 3 was euthanatized 21 days post-inoculation. Cat No. 1 had lesions of gram-positive bacterial septicemia. Necrotizing encephalitis, myelitis, disseminated skeletal muscle necrosis, hepatic necrosis, interstitial pneumonia, and renal tubular necrosis were the main lesions in cat Nos. 2 and 3. The cats that were not given methylprednisolone acetate remained clinically normal except for slight weight loss in cat No. 6. All three of these cats were euthanatized 55 days post-inoculation. Mild myositis and encephalitis were noted on microscopic examination of tissues from these three cats. Neuromuscular lesions were not seen in six control cats (Nos. 7-12) not inoculated with N. caninum and euthanatized 21 or 22 days after administration of the first two doses of methylprednisolone acetate (40 mg/kg), given at a weekly interval.

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.

A number of viruses cause acute central nervous system disease. The two major clinical presentations are aseptic meningitis and the less common meningoencephalitis. Clinical virology laboratories are now more widely available than a decade ago; they can be operated on a modest scale and can be tailored to the needs of the patients they serve. Most laboratories can provide diagnostic information on diseases caused by enteroviruses, herpesviruses, and human immunodeficiency virus. Antiviral therapy for herpes simplex virus is now available. By providing a rapid diagnostic test or isolation of the virus or both, the virology laboratory plays a direct role in guiding antiviral therapy for patients with herpes simplex encephalitis. Although there is no specific drug available for enteroviruses, attention needs to be paid to these viruses since they are the most common cause of nonbacterial meningitis and the most common pathogens causing hospitalization for suspected sepsis in young infants in the United States during the warm months of the year. When the virology laboratory maximizes the speed of viral detection or isolation, it can make a significant impact on management of these patients. Early viral diagnosis benefits patients with enteroviral meningitis, most of whom are hospitalized and treated for bacterial sepsis or meningitis or both; these patients have the advantage of early withdrawal of antibiotics and intravenous therapy, early hospital discharge, and avoidance of the risks and costs of unnecessary tests and treatment. Enteroviral infection in young infants also is a risk factor for possible long-term sequelae. For compromised patients, the diagnostic information helps in selecting specific immunoglobulin therapy. Good communication between the physician and the laboratory will result in the most benefit to patients with central nervous system viral infection.

Fifty-four patients with acute lymphoblastic leukemia (ALL: 1 relapse, 21 high risk first complete remission (CR 1), 29 second CR (CR 2), and 3 third CR (CR 3) were treated by autologous bone marrow transplantation at three centers. Before storage, the marrows were purged ex vivo with appropriate MAbs RFAL3 (CD10), SB4 (CD19), and RFT2 (CD7), with rabbit serum as the source of complement. All patients received total body irradiation either 750 cGy (middose 15 cGy/min) as a single fraction or 6 x 200 cGy over 3 days (midline dose 16 cGy/min) with lung shielding from 1,100 cGy. The patients who received 750 cGy also received cyclophosphamide or the same drug combined with ara-C or prednisone, teniposide, vincristine, ara-C, and dauno-rubicin. Patients receiving 200 cGy x 6 also received either cyclophosphamide, melphalan, or ara-C and cyclophosphamide. Three patients died of post transplantation complications (interstitial pneumonia, hepatitis B liver necrosis, or encephalitis). This gives a procedure related mortality of 5%. Nonfatal complications were 10 cases of septicemia, 4 interstitial pneumonia, 2 interstitial nephritis, 1 veno-occlusive disease (VOD), and 1 case of hemolytic uremic syndrome. The patient autografted in relapse died of relapse within 2 months. In CR 1 6 or 21 patients have had a relapse, and the actuarial leukemia free survival from CR is 65% (median follow-up 16 months). In CR 2-3 18 of 32 patients have relapsed, and the actuarial leukemia free survival is 31% (median follow-up 18.5 months) from CR. Twelve patients have achieved an inversion, (i.e., present CR longer than previous CR), with a further seven with the potential to achieve inversion. We conclude that ABMT in high risk ALL has a low procedure related mortality (5%), and there are few other complications. The in vitro purging with MAbs had no adverse effect on bone marrow reconstitution, but this study was not designed to demonstrate its antileukemic efficacy. The actuarial leukemia free survival time in the present study for patients with high risk CR 1 and the inversions in CF 2-3 are promising and indicate a potential beneficial effect of ABMT.

Two children aged 7 months with eczema herpeticum received treatment consisting of intravenous acyclovir and human plasma with a high titer of herpes simplex virus antibodies. One recovered following two recurrences, but the other died rapidly, suffering both septicemia due to Pseudomonas aeruginosa and herpetic encephalitis. In both cases, the virus involved was a herpes simplex virus type 1 (HSV 1). The various isolates obtained before, during and after treatment remained equally sensitive to acyclovir. These observations highlight three points: the unpredictable and sometimes dramatic development of eczema herpeticum in the young child; the urgency of early diagnosis and treatment; the role of environment in viral contamination.

This study included 44 children undergoing autologous marrow transplantation for leukemia between August 1979 and June 1987. Three of them received a second transplant. In the phase of neutropenia, 38 children presented with fever. Nineteen septicemia occurred (13 Gram positive cocci, 6 Gram negative bacteria), and 2 interstitial pneumonitis were observed. All children with documented infection or a fever of unknown origin recovered after treatment, except 3, who died from infection. The latest antimicrobial therapy used was a combination of an aminoglycoside and a third generation cephalosporin. When necessary, vancomycin or amphotericin B were added. After engraftment (granulocyte count greater than 0.5 X 10(9)/l) 14 septicemia (which recovered) and 10 herpes zoster infections were observed. Only one patient died of infection (herpes zoster with encephalitis).

We describe an infant with meningitis and septicemia due to infection with two different strains of Haemophilus influenzae, with a urinary tract infection due to Escherichia coli and in whom herpes virus encephalitis was diagnosed within three days. Acinetobacter calcoaceticus septicemia developed three weeks later. No immunological deficiency could be demonstrated in the patient who recovered finally, albeit with sequelae due to encephalitis.
