A two year old boy exhibited not only clinical manifestations which suggested a recurrence of Kawasaki disease (KD) but also evidence of a primary infection by Epstein-Barr virus (EBV) including tonsillitis, splenomegaly and atypical lymphocytosis in the peripheral blood. An inverted CD4/CD8 ratio in lymphocyte subsets suggested the presence of infectious mononucleosis (IM). Epstein-Barr virus titers (viral capsid antigen-immunoglobulin G 1:20; Epstein-Barr virus-associated nuclear antigen < 1:10) showed an acute EBV infection and the presence of EBV genome in the blood was determined by the polymerase chain reaction technique. In Japan, the peak incidence of KD and IM is in children under 4 years of age. From the investigation of EBV titers, it has been reported that some patients with KD develop an associated, unusual primary EBV infection. Kawasaki disease concurrent with a primary EBV infection as in this case, suggests the possibility of an etiologic agent related to the KD rather than to the EBV infection itself.

Biapenem (L-627) was given intravenously to 17 children with acute bacterial infections including 3 with purulent tonsillitis, 1 with bronchitis, 4 with pneumonia, 2 with sepsis, 3 with pyelonephritis, 2 with SSSS. (2 cases are omitted from evaluation because of Mycoplasma pneumonia and infectious mononucleosis). Daily dosages per kg bodyweight ranging from 18.3 to 60 mg were given in 3 divided doses per day for 4 to 6 days. Clinical responses were excellent in 12 (80%), good in 2 (13.3%), fair in 1 (6.7%) and poor in 0 (0%), with an overall efficacy rate of 93.3%. Good bacteriological responses were obtained in all of the 9 cases from which pathogens were identified. A side effect is observed in only 1 case with mild diarrhea. The above results suggest that L-627 is a useful new carbapenem derivative for the treatment of bacterial infections in children.

Acute idiopathic thrombocytopenic purpura (ITP) often appears to be related to the sensitization by some viral infections. However, the causative viral agents are not identified in most cases. Although the primary infection with Epstein-Barr virus (EBV) occurs during early childhood in Japan, the majority of cases are usually asymptomatic. A minority are associated with acute infectious mononucleosis (IM), which is characterized by fever, tonsillitis, lymphadenopathy, splenomegaly and liver dysfunction. In this report, three cases are described of children with EBV-induced ITP who clinically had atypical findings of IM. Their primary EBV infections were confirmed by serological test and, in addition, were verified by the enhanced expression of activation antigens (HLA-DR and CD45RO) on T cells as well as the inverted ratio of CD4+ to CD8+ subsets. These observations imply that ITP can occur as one of the host responses during primary EBV infections, irrespective of clinical manifestations. Evaluation of lymphocyte subpopulations may be useful for the assessment of primary EBV infection in ITP.

Common causes of acute laryngotracheobronchitis (LTB) are viral infections. More rarely, bacterial germs, unspecific irritants, foreign bodies, rachitic laryngospasm, mild malformation, tumours, C1 esterase inhibitor deficiency, bilateral vocal cord paralysis, and psychogenic laryngospasm may be responsible for croup. Symptoms similar to epiglottitis may occur in pharyngitis based on common bacterial tonsillitis or infectious mononucleosis and peritonsillar abscess. It is decisively important to establish a precise diagnosis to provide for an appropriate therapy. Viral croup of mild degree is often sufficiently treated by cold and moistened air and--if necessary--prednisolone. In serious disease, oxygen insufflation and adrenaline (epinephrine) are useful. Recurrent croup is due to an unspecific hyperreactivity of tracheobronchial mucosa. It often leads to asthma. Consequently, preventive measures have to be considered similar to patients with bronchial hyperreactivity. Vaccination with haemophilus influenzae type b vaccine has proved effective and safe. The disease has therefore become impressively less frequent.

The role of four oral flora organisms (Fusobacterium nucleatum, Prevotella intermedia, Porphyromonas gingivalis and Actinobacillus actinomycetemcomitans) was investigated in 22 patients with infectious mononucleosis. Immunoglobulin-G class antibody titres to these organisms were measured by enzyme-linked immunosorbent assay. Serum levels in the patients were determined at day 1 and 42-56 days later. Significantly higher antibody levels to F. nucleatum and Pr. intermedia were found in the second serum sample of patients as compared to their first sample. The elevated antibody levels to F. nucleatum and Pr. intermedia, known oral pathogens, suggest a potential pathogenic role for these organisms in the pharyngo-tonsillitis associated with infectious mononucleosis.

Sequential bacterial samples were obtained from the tonsillar surface of 19 consecutive patients (12 females, seven males; mean age 16.1 years, range four to 24 years) suffering from infectious mononucleosis with membranous tonsillitis. The specimens were examined with respect to aerobes (culture on blood and chocolate agar plates) and proportions of bacteria coated with immunoglobulins (secretory IgA, IgG, IgM) by using an immunofluorescence assay. In the early stage of the membranous tonsillitis phase, attachment of secretory IgA (SIgA) and IgG to the bacteria was greatly suppressed, as compared with healthy controls. Coating with IgM was evident only late in the membranous tonsillitis phase but was contracted and still evident even after the clinical throat symptoms had abated. The findings suggest that the B-lymphotropic Epstein-Barr virus, causative agent of infectious mononucleosis, exerts a transient suppression of immunoglobulin-coating of bacteria harboured on the tonsillar surfaces, with consequent abundant bacterial attachment to the epithelial cells and massive bacterial colonization on the palatine tonsils.

Previous investigations of exfoliated oropharyngeal cells from individuals suffering from infectious mononucleosis (IM) suggested that the oropharyngeal epithelia are the primary target and also the site of life-long persistence of the Epstein-Barr virus (EBV). This concept was widely accepted. However, the investigation of histological sections with more sensitive EBV detection techniques has drawn this concept into doubt since EBV proved to be constantly absent in normal epithelial cells. To elucidate the discrepancy, throat washings and peripheral mononuclear blood cells from 16 patients suffering from IM were investigated for EBV-DNA and EBV gene products employing highly sensitive in situ hybridization, immunocytochemistry, and polymerase chain reaction. Although all patients exhibited latently infected B lymphocytes in peripheral blood, samples of exfoliated oropharyngeal cells were constantly EBV-negative with the exception of three cases. In these cases, the patients additionally suffered from purulent ulcerating tonsillitis, EBV-infected B cells, but no EBV-infected epithelial cells were detectable. These findings support the view that recirculating lymphocytes of B-cell origin, but not epithelial cells are the initial target of EBV during primary infection and that B cells also represent the site of life-long viral persistence.

The present study investigated 54 pediatric patients with acute Epstein-Barr virus (EBV)-induced infectious mononucleosis (IM) in Japan. Most of the acute cases clustered within the first 5 years of life, and the peak incidence was observed at around 4 years of age. These patients were arbitrarily separated into three age groups (less than 3 years, 3-5 years, and 6-14 years). Fever, pharyngitis, lymphadenopathy and hepatomegaly were detected in more than 80% of all cases. Tonsillitis and splenomegaly were present in about 60% of cases. Skin manifestations and eyelids edema were less often detected in the older age group than in the young age groups. In addition to an increase of total white blood cell and lymphocyte counts in the peripheral blood, a significant increase in the percentage of CD3+ CD8+ HLA-DR+ T cells was always observed. Epstein-Barr virus seropositivity increased soon after birth and reached approximately 70% around 3 years of age. Close to 100% of the adult controls were EBV seropositive. The results suggest that EBV-induced acute IM is a disease of early childhood in Japan.

Acute otitis media and tonsillopharyngitis are two of the most common diseases in pediatric clinical practice. Careful examination of the ears and the tonsils are mandatory in the evaluation of a febrile child. Acute otitis media usually can be diagnosed by a carefully taken history and examination alone. The infection usually requires antibiotic treatment, with amoxicillin being still recommended as the first choice drug. Pharyngitis and tonsillitis are more variable in their origin, the majority of cases is caused by different viruses. However, clinical examination alone is not specific enough to rule out the most important bacterial pathogen, group A streptococcus, which still has to be treated by penicillins. Thus, rapid test methods and classic bacteriological culture are used to assess group A streptococcus infections. Infectious mononucleosis and diphtheria are the most important diseases to be considered carefully in each patient.
