Genital mycoplasmas have been implicated in different neonatal diseases as pneumonia, sepsis and meningitis. This prospective study was conducted to specify their role in these diseases. POPULATION AND METHODS--A pharyngeal or tracheal swab specimen for mycoplasmas culture was obtained from 100 infants admitted consecutively to the Neonatal Care Unit (NCU) during the first 24 hours of life. Mycoplasma culture of blood and cerebrospinal fluid was also performed. Pharyngeal and/or tracheal specimens were collected again on days 5, 15 and 28 if the child was still in the NCU. Mycoplasma hominis (Mh) and Ureaplasma urealyticum (Uu) were identified by culture in a modified Hayflick's medium. RESULTS--Three-hundred and ten pharyngeal or tracheal swabs were obtained (100 on day 0, 89 on day 5, 72 on day 15 and 49 on day 28). Twenty-one infants had one or more positive swabs in the first five days of life (20 on day 0 and one on day 5); those forming the "Myco+" group and the others forming the "Myco-" group. Uu was isolated alone from 20 infants, associated with Mh from one. Both groups were similar for gestational age, birth weight, maternal fever during labor, prolonged rupture of the fetal membranes or chorioamnionitis and for the incidence of acute respiratory distress. There was a statistically significant difference for the route of delivery (chi 2 < 0.02). One blood culture (from 92 performed) was positive for Uu and another positive for Uu and Mh. Both children were cured without any specific mycoplasmacidal therapy. Three children had probable Uu infection and were also cured without specific therapy. CONCLUSIONS--A pharyngeal colonization with genital mycoplasmas is common in the first days of life (21%) but our data do not allow us to conclude that they are accountable for newborn infections.

We studied the clinical efficacy of biapenem (L-627), a new parenteral carbapenem beta-lactam antibiotic in the pediatric field. L-627 was administered intravenously to 11 patients with ages ranging 2 months to 10 years and 5 months with acute infectious diseases. Doses ranged 28.1 to 72.6 mg/kg/day. The diagnosed diseases included 7 respiratory tract infections, 1 purulent meningitis, 1 sepsis, 1 cervical lymphadenitis and 1 urinary tract infection. Two of these cases one with Mycoplasma infection and the other which had been administered with other antimicrobial agents were not evaluated. The clinical efficacy rate was 77.8% (7/9) and the bacteriological eradication rate was 66.7% (4/6). Laboratory examinations revealed that there was one case with elevated liver enzyme levels with showing elevation of GOT, GPT and LDH. No other side effects attributable to this drug were observed. Thus, it appears that L-627 is a useful antibiotic in treating moderate to severe acute bacterial infections in children.

The role of genital mycoplasmas in the pathogenesis of neonatal infection is incompletely understood. We performed nasopharyngeal, blood and cerebrospinal fluid (CSF) cultures for Mycoplasma hominis and Ureaplasma urealyticum in 69 neonates who underwent a diagnostic workup for suspected sepsis. The mean gestational age was 35.9 weeks (range, 25 to 42 weeks) with a mean birth weight of 2386 g (range, 652 to 4420 g). Twenty-seven infants (39.1%) had positive nasopharyngeal cultures; 6 were positive for M. hominis, 10 for U. urealyticum and 11 for both organisms. Seven (26%) of these 27 patients developed chronic lung disease compared with 2 (4.7%) infants in the non-colonized group. Nine infants had positive CSF cultures for M. hominis and one infant had a positive CSF culture for U. urealyticum. All blood cultures were sterile. One of the infants with a positive CSF culture for M. hominis had clinical evidence of systemic infection. All of the infants were treated with antibiotic agents that were not active against mycoplasmas. These data indicate that genital mycoplasmas can be found commonly in the CSF and nasopharynx of infants with suspected sepsis. Their etiologic role in the causation of infection and chronic lung disease, however, remains unclear.

We retrospectively studied 42 patients hospitalized for Stevens-Johnson syndrome at the Veterans General Hospital-Taipei between 1979 and 1991. Twenty-seven patients were males and 15 females; the ages ranged from 7 months to 82 years old with a mean age 50. The most common precipitating factor was drugs among which diphenylhydantion was the leading offender followed by nonsteroidal anti-inflammatory agents and allopurinol. Sixteen cases might be etiologically associated with infection, including 13 with upper respiratory infection, one with acute hepatitis B, one with pulmonary tuberculosis, and one with fever of unknown origin that was suspected to be viral infection. Although mycoplasma infection was thought in the literature to be a common etiologic factor of Stevens-Johnson syndrome, it was scarcely found in our study. Four patients were not treated with systemic steroids but still recovered uneventfully. Systemic steroid as a whole was not proved to be necessary, but early large-dose steroid therapy might abbreviate the course of the disease. The mortality rate was 11.9% which differs unremarkably from the reported rate (5-15%). Two patients died of pneumonia with sepsis, one of hemorrhagic shock (bleeding of adenocarcinoma of stomach), one of aspiration pneumonia, and one of sepsis with disseminated intravascular coagulation, upper gastrointestinal bleeding, and hyperglycemic hyperosmolar nonketotic coma.

Pericardial abscess is a very rare complication of sepsis. Authors describe the case of a 69-year-old woman. In her case staphylococcus sepsis led to pericardial abscess. During the course positive blood cultures (3x) indicated the sepsis and pus was obtained from the left pleural cavity (pleuropneumonia). Concomitant purulent process in the left shoulder also was noted. Decline immunity due to long-standing corticoid therapy (prednisone) for proctocolitis idiopathica was observed. Following antibiotic treatment successful surgical evacuation of the pericardial abscess was performed.

Severe CAP is a life-threatening condition defined by the presence of respiratory failure or symptoms of severe sepsis or septic shock. It accounts for approximately 10% of hospitalized patients with CAP. The majority of patients with severe pneumonia have underlying comorbid illnesses, with COPD, alcoholism, chronic heart disease, and diabetes mellitus being the most frequent. S. pneumoniae, Legionella spp, GNEB (especially K. pneumoniae), H. influenzae, S. aureus/spp, Mycoplasma pneumoniae, respiratory viruses (especially influenza viruses), and P. aeruginosa represent the most important causative organisms of severe CAP. Rapid initiation of appropriate antimicrobial treatment is crucial for a favorable outcome. Initial antimicrobial treatment should be based on an epidemiological (empiric) approach. Microbial investigation may be helpful in the individual case but is probably more useful to define local antimicrobial policies based on local epidemiologic and susceptibility patterns. Mortality rates range from 21% to 54%. The most important prognostic factors include general health state of the patient, appropriateness of initial antimicrobial treatment, and the existence of bacteremia, as well as factors reflecting severe respiratory failure, severe sepsis, septic hypotension or shock, and the extent of infiltrates in chest radiograph. Initial antimicrobial treatment should consist of a second (or third) generation cephalosporin and erythromycin. Modifications of this basic regimen should be considered in the presence of distinct comorbid conditions and risk factors for distinct pathogens. Promising new approaches of nonantimicrobial treatment, including noninvasive ventilation, treatment of hypoxemia, and immunomodulation, are under investigation.

We classified 1017 patients with community-acquired pneumonia requiring hospitalization experienced in Kawasaki Medical School Kawasaki Hospital during the past 15 years into five age groups (< or = 54 years old, 55-64 years old, 65-74 years old, 75-84 years old, > or = 85 years old). With particular emphasis on the elderly patients, we then compared the clinical and microbiological findings in the five groups. The results were as follows; (1) Half of patients in the over 85 years old group were bed-ridden. (2) The proportion receiving antibiotics before hospitalization decreased with age. (3) There were striking atypical pneumonic symptoms, such as dyspnea and consciousness disturbance in the two age groups over 75 years old. (4) Hypotension (shock) increased with age. (5) Markers of nutritional conditions, such as serum protein, albumin, cholinesterase, and hypoxia remarkably increased in the two age groups over 75 years old. (6) There were no significant differences in the isolation rate of etiological microorganisms. (7) The number of polymicrobial agents in the < or = 54 years old group was lower than that in the other age groups. (8) Mycoplasma pneumoniae was most significantly higher in < or = 54 years old group, Haemophilus influenzae in patients 55-64 years old, and Streptococcus pneumoniae in both 65-74 and 75-84 years old groups. (9) The isolation rate of MSSA, gram-negative bacilli such as Klebsiella pneumoniae, Pseudomonas aeruginosa, respiratory viruses increased with age. (10) The amount of sepsis increased with age. (11) The prognosis was poor in the two groups over 75 years old because the mortality rate (over 10%) was higher that for the other age groups.

The pathogenicity of the nondiphtheria corynebacteria, most commonly known as coryneform bacteria in humans has been recognized in the last two decades. Corynebacterium xerosis is part of the normal flora of the skin, nasopharynx, conjunctives and it has recently been isolated from vaginal swabs. During the last few years, there has been an increased number of case reports claiming an association of C. xerosis with diseases, like septicemia, endocarditis, pleuropneumonia, peritonitis, osteomyelitis, septic arthritis, mediastinitis, meningitis, ventriculitis specially in immunocompromised patients or surgical patients. Infections due to C. xerosis have been reported rarely in newborn. We report a case of sepsis due to C. xerosis in a newborn without evident immunodeficiency. Our case further support the recognition of C. xerosis as a human pathogen and reinforces the fact that it should not be routinely considered as a contaminant.

The trial was carried out in a large Hungarian 2000 sow "farrow-to-finish" production unit. Out of a total number of 15,841 evaluated growing/finishing pigs, 1319 pigs died or were emergency-culled and were post-mortem routinely examined. For the purpose of this study the emergency-culling and mortality were recorded into the same category. The average annual emergency-culling/mortality rate was unusual high (8.62%). Five body condition related categories were registered. The majority of the mortality comprised animals of body condition "below average", representing 891 pigs (67.56%) and "average" (407 pigs = 30.85%). The rest of the examined animals comprised 17 pigs (1.29%) "emitted", 2 pigs "kachexia" (stunted pig) or "fat" (0.15% each). The overall study showed that gastrointestinal tract disorders (395 animals = 29.95%) were the most frequently recorded cause of emergency-culling or mortality. Both inflammatory disorders (7.66%) and rectal stricture (7.51%) were in this category the most frequent diagnosis followed by rectal prolapse (5.92%). Gastric ulcers comprised 4.55% of the necropsied animals. Torsion of abdominal organs and miscellaneous cases represented slightly more than 2% of the post-mortem examined pigs. Lesions which involved the respiratory system, comprised 14.85% of the necropsied pigs. Bronchopneumonia due to Mycoplasma hyopneumoniae occurred in 5.61%, embolic suppurative or necrotic pneumonia in 4.78% and pleuropneumonia due to Actinobacillus pleuropneumoniae in 3.1% of the cases. Diseases involving the urinary system were diagnosed in 21 cases (1.59%). Five cases of skin disorders were registered (0.38%). Cardiovascular disorders were represented by congestive heart failure (31 pigs = 2.35%), pericarditis (22 animals = 1.66%) or endocarditis (21 pigs = 1.60%). Cardiomyopathy was found in 15 (1.2%) animals. Lesions involved the locomotor system ranked second of all cases (15.92%). Claw lesions accounted 13.72%, arthritis 2.13% of the animals and luxation or fracture was diagnosed only in one case (0.07%). Systemic infections were reported in 96 cases (7.28%) including polyserositis (4.09%), erysipelas, edema disease or miscellaneous causes (each category slightly more than 1%). Genetic problems were involved in 8.19% of the fatal cases and social stress or cannibalism related culling or mortality comprised 37 animals (2.81%). In 161 cases (12.20%) of the mortality the causes of death were not established. Two or more lesions related to culling or mortality were found in 320 pigs (24.26%, p < 0.001). The most common diagnosed pathologic changes in association with other lesions were Mycoplasma hyopneumoniae caused bronchopneumonia (4.09%), embolic suppurative or necrotic pneumonia (4.55%), followed by inflammatory gastrointestinal problems (3.10%), gastric ulcer (2.35%), claw lesions (2.19%) and arthritis (1.14%). It appears from the presented study that a routine post-mortem examination of all emergency-culled or dead pigs over a long period of time gives a clear picture of causes of mortality enabling the management to plan management strategies as vaccination programs, genetic improvements and optimising environmental conditions.
