One-hundred and seventy-one cases of pertussis were observed at the Institute of Infections Diseases and at the 2nd Division of Infectious Diseases of the Policlinico Umberto I in Rome from January 1, 1987 to June 30, 1991. All subjects were treated according to a therapeutic protocol consisting of macrolides (erythromycin or myocamicin) at doses of 40-50 mg/die, betamethasone 0.1 mg/kg/die, specific immunoglobulin G at doses of 0.5 ml/kg repeated after 24 hours (new born babies and babies still unweaned) and oxygen therapy during the paroxystic fits. In 20 patients who were over the first year of life and who had serious asphyxiated fits, bronchodilators (trimetochinol or salbutamol) were added to the previous therapeutic scheme. Our data show both efficacy of therapeutic protocol and importance of early starting the treatment to shorten the length of disease, the strength of asphyxiated fits, and the risk of contagion.

During the 1970s and the early 1980s, immunization practices in the United States were unchanged. Immunization against pertussis, tetanus, diphtheria, measles, mumps, rubella, and polio were routinely administered to children. Infections with these organisms declined dramatically. Nonetheless, research was vigorous, culminating in the 1980s in new vaccines and changes in immunization strategies and practices. This presentation will focus on these changes: universal hepatitis B immunization; two-dose schedule for the measles, mumps, rubella (MMR) vaccine, Hemophilus influenza type B vaccine for infants, acellular pertussis vaccine as booster immunizations, the inactivated polio vaccine, and the yet-to-be-licensed live varicella vaccine.

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.

Infections of the deeper respiratory airways can contribute to the progression of chronic asthmatic bronchitis. In the present report a number of microorganisms affecting the number of beta-adrenoceptors in guinea-pig lung homogenates are described. Haemophilus influenzae, Streptococcus pneumoniae, Bordetella pertussis and Escherichia coli O111B4 induced a significant decrease of the number of beta-adrenoceptors (by approximately 20%). Staphylococcus aureus, influenza A virus and Escherichia coli J5 were not active. These data point to a common factor shared by gram-negative bacilli; i.e. endotoxin. Purified endotoxin of E. coli O111B4 also decreased the number of beta-adrenoceptors, while E. coli J5-LPS did not. This suggests that neutral polysaccharides of bacterial cell walls, especially those in the 'O'-antigenic side chain of gram-negative endotoxins may be responsible for the decrease of beta-adrenoceptor number and therefore contribute to the pathogenesis of chronic asthmatic bronchitis. Intact endotoxin seems to be necessary since neither the isolated lipid nor the polysaccharide part of E. coli O111B4 LPS affected the number of beta-adrenoceptors in the lung.

Among the most important responsibilities of a hospital's employees' health service is the prevention or prompt identification of infectious illnesses among staff members. Infections constitute a major health hazard of hospital employment and, both intrinsically or as a consequence of subsequent transmission to hospitalized patients, can have devastating consequences. The risks associated with tuberculosis, viral hepatitis, rubella, herpes, meningococcal disease, and scabies are generally acknowledged and methods of control have been suggested. In addition, immunizations against diphtheria and influenza have been advised under certain circumstances. Respiratory syncytial virus and pertussis probably account for some upper respiratory tract illnesses among personnel and may lead to serious morbidity in pediatric patients. Laboratory-acquired infections can be diverse and exotic. Control measures should include surveillance, appropriate immunizations, epidemiologic investigation coordinated with infection control, antibiotic prophylaxis when indicated and environmental safeguards.

Infections were considered to be etiological factors in 29 patients (10%) with infantile spasms; congenital CMV (n = 5), congenital or acquired CMV (n = 1), acquired CMV (n = 5), congenital rubella (n = 2), herpes simplex virus (n = 5), enterovirus (n = 1), adenovirus (n = 1), viral encephalitis of unknown agent (n = 3), meningococcus (n = 4), pneumococcus (n = 1) and pertussis (n = 1). The children with congenital infections had long-lasting tremor and convulsions from birth. Early EEG pattern was characteristic for children with herpes encephalitis but not for other patients. Infantile spasms appeared only some weeks after viral encephalitis. One patient with enterovirus and another with probable adenovirus infection had necrotic changes in their brain CT resembling those of herpes encephalitis. The response to ACTH was poor (38%) compared to the whole series (60%). The long-term outcome was also poor compared to the whole series; mental retardation in 90%, convulsions in 62%, abnormal EEG in 89%. Four children died during the follow-up of 7 years. Autopsy showed disseminated CMV infection in one patient and chronic CMV infection in another. The outcome of children with infectious etiology appears to be particularly poor. Thus, the prevention and specific diagnosis and treatment are important. Steroid therapy should be avoided in children with a history of herpes virus encephalitis (CMV, herpes simplex) in the past.

To investigate the frequency of unrecognized Bordetella pertussis infections in adults, we performed IgA and IgG ELISA antibody studies with four B. pertussis antigens--i.e., lymphocytosis-promoting factor, filamentous hemagglutinin, pertactin, and fimbriae-2--in 51 health care workers from whom six consecutive yearly serum samples (from 1984 to 1989) were available. Overall, 90% of the subjects had a significant increase in antibody (IgA or IgG) to one or more antigens between 2 consecutive years during the 5-year study period; 55% of subjects had evidence of two infections, 17% had three infections, and 4% had four infections. Infections occurred in all study years, with the following rates: 1984-1985, 32%; 1985-1986, 24%; 1986-1987, 40%; 1987-1988, 29%; and 1988-1989, 43% (P = .12). Some antibody rises may have been due to responses to cross-reacting antigens (Bordetella parapertussis, nontypable Haemophilus influenzae), but overall these data suggest that B. pertussis infections in adults are common, endemic, and usually unrecognized.

Respiratory infections, especially community-acquired forms of pneumonia (CAP), are challenging for clinicians because (1) a causative microorganism can only be found in about 50% of cases; (2) initial therapy, therefore, must be based on a probable or most likely etiology in the context of the patient's overall medical condition; and (3) new microbes or those considered previously as normal flora or less virulent forms seem responsible for some cases. It is important to be acquainted with new causes of infection which include Legionella species, Chlamydia pneumoniae, diphtheroids in certain instances (Corynebacterium pseudodiphtheriticum), and viruses such as the Hanta strains. Infections with Bordetella pertussis are increasing. However, the ever present and most common cause of CAP, Streptococcus pneumoniae, continues to present problems because of increasing antibiotic resistance, the high case fatality rate when bacteremia accompanies pneumonia, and the inability to give prophylactic immunization to all people with risk factors for this infection.

In the first half of the 20th century, improved living conditions, preventive measures, vaccines and antibiotics led to a marked reduction in morbidity and mortality from infectious diseases. It was predicted that the conquest of all infectious diseases was imminent. However, 50 years later, in 1999, they were still the major cause of disease worldwide, and caused nearly one third of all deaths (a total of 55.9 million). The eradication of smallpox in the 1970s and the approaching eradication of poliomyelitis represent major achievements. The prevalence of measles, pertussis and tetanus neonatorum is also markedly reduced, but still 1.5 million children in developing countries die each year because of lack of vaccines. Malaria and tuberculosis are re-emerging. Tuberculosis and HIV/AIDS are the diseases with known aetiology that cause most deaths, altogether 5 million each year. Respiratory and gastrointestinal infections cause 6.5 million deaths annually. Infections in the immunocompromised host have become a "trade mark" of today's advanced medicine. Almost every year, new diseases related to new micro-organisms are described; over the last 30 years, approximately 40 new diseases/micro-organisms have been diagnosed. Among the best known are HIV/AIDS, peptic ulcer caused by Helicobacter pylori, Legionnaires' disease, borreliosis (Lyme disease), hepatitis C, gastroenteritis caused by rotavirus, and Ebola haemorrhagic fever. Antimicrobial resistance development of micro-organisms has become one of the major health problems worldwide; a number of preventive measures are being introduced.

Infections jeopardize children on immunosuppression after organ transplantation. Immunization is protective in healthy children. The aims of this study were to analyze the rate and efficacy of immunization in 62 children undergoing dialysis and renal transplantation (RTPL) between 1987 and 2000. The analysis was based on clinical findings, vaccination certificates, and measurement of specific serum antibodies. A member of the renal unit administered vaccinations. All 62 patients were immunized against diphtheria, tetanus, pertussis, poliomyelitis, measles, mumps, rubella, and hepatitis B. Since introduction in 1991 and 1995, 44 and 42 children were also vaccinated against influenza and Hemophilus influenzae type b, respectively. Of 16 patients with a negative history, 14 were given varicella vaccine; 16 children on peritoneal dialysis (PD) or with nephrotic syndrome were immunized against Streptococcus pneumoniae. All vaccinated patients had detectable serum antibodies against measles, mumps, rubella, varicella, hepatitis B, H. influenzae, and S. pneumoniae. There were 3 infections despite vaccination; 1 patient developed varicella after RTPL and 1 patient on PD had 2 episodes of peritonitis caused by H. influenzae and S. pneumoniae. In conclusion, monitoring and administration of the vaccines by the renal team enabled a high immunization rate. Whether vaccines, as documented by antibody titers, or by the low prevalence in the general population promoted the low prevalence of infections remains open, as there were at least a few vaccination failures.
