Cefozopran (CZOP) was administered via intravenous injection to 9 patients (ages ranging from 1 month to 13 years) with pediatric bacterial infections, at daily dose levels between 56.7 and 200 mg/kg, divided into 3 or 4 doses. The following results were obtained. 1. Eight patients, including 1 with purulent meningitis, 1 with sepsis, 3 with acute pneumonia and 3 with lymphadenitis, were treated and subjected to clinical evaluation. Clinical effects were excellent in 6 cases and good in 2, with an overall efficacy rate of 100%. One case with pyoderma was not evaluated because of a combined use of an external antibiotic. 2. Organisms suspected as pathogens included 5 strains: 3 strains of Haemophilus influenzae, 1 strain of Staphylococcus aureus and 1 of Escherichia coli. Bacteriologically, all the strains were eradicated. 3. Side effects or abnormal laboratory test results were observed in 4 cases; wheal in 1 case, elevated GOT and GPT in 2 cases and eosinophilia in 1 case. 4. From the results described above, we considered that CZOP would be an effective drug for use in pediatric bacterial infections.

Group A streptococci (S. pyogenes) possess a number of capsule and cell wall associated components and release many extracellular proteins (toxins and hydrolytic enzymes) that are known or thought to contribute to the virulence and pathogenicity of the microorganism. Groupe A streptococci cause a wide array of infections, the most frequent of which are acute pharyngitis and pyoderma with two severe sequelae (acute rheumatic fever and glomerulonephritis). Other manifestations are scarlet fever and various soft tissue infections as well as sepsis and the recently characterized streptococcal toxic shock syndrome. The somatic components of group A streptococci include cell wall M protein, capsular hyaluronic acid, lipoteichoic acid, peptidoglycan, fibronectin binding protein, C5a peptidase and receptors for various human plasma proteins particularly IgA and IgG. The extracellular products are numerous and consist of among others the hemolytic toxins streptolysins S and O, hyaluronidase, streptokinase and cysteinyl proteinase as well as the superantigens erythrogenic toxins A and C also known as pyrogenic exotoxins.

Eosinophilic pustular folliculitis (EPF) is a cutaneous inflammatory follicular disorder of unknown etiology. The diagnosis is made on the basis of clinical and histopathologic features. We describe two patients who had recurrent episodes of pruritic follicular papular and pustular lesions on the face, extremities, and trunk. The eruptions lasted for 1 month with intermittent remissions. Laboratory tests disclosed no infectious or parasitic etiology in patient 2. In patient 1 we isolated methicillin-resistant Staphylococcus aureus in a blood culture. He had sepsis with lung and liver involvement. EPF is a self-limited dermatosis. On occasion, skin lesions may become superinfected, resulting in localized pyoderma or rarely systemic infection (sepsis). Histologically both of our patients showed a moderate mixed inflammatory infiltrate with numerous eosinophils centered around hair follicles. Their lesions responded well to topical corticosteroids.

Varicella infection usually occurs in childhood and is uncommon in neonates. We reported 26 cases of neonatal varicella seen at the Queen Sirikit National Institute of Child Health, Bangkok, from 1988 to 1995. The sex ratio of male to female was equal. The age of onset was between 6 to 27 days. Twelve cases contracted varicella from mothers who were infected between 6 days before delivery to 2 days after delivery (perinatal varicella) and fourteen cases contracted varicella from mothers or siblings in the postnatal period (postnatal varicella). All babies developed vesicular rash. Intravenous acyclovir was given in high risk and severe cases (nine perinatal and three postnatal varicella patients). Complications of neonatal varicella included clinical sepsis 8 cases (30%), pneumonia 7 cases (26%), pyoderma 9 cases (35%) and hepatitis 1 case (4%). There was no statistical difference between the complications of perinatal and postnatal group (p > 0.05). No death was observed during this study. Clinical manifestations of neonatal varicella varied from mild to severe, depending on the onset of rash in the mother and baby and mode of transmission of the disease. Although we have no varicella-zoster immunoglobulin (VZIG), acyclovir therapy is beneficial in the treatment of neonatal varicella.

Trimethoprim-sulfadiazine (TMP-SDZ) (Tribressin tablets 120 - 100 mg sulfadiazine, 20-mg trimethoprim [Coopers Animal Health, Inc., A Pitman-Moore Company, Mundelein, Ill.]) is a broad spectrum antibiotic combination effective in the treatment of bacterial pneumonia, urinary tract infections, pyoderma, meningitis, and prostatitis.(1) In clinical trials in puppies and adult dogs, TMP-SDZ was considered safe at both the manufacturer's recommended dose (15 mg/kg, b.i.d., or 30 mg/kg, u.i.d., per os for < 14 days(2)) and at 10 times that dose for 20 dayS.(3) Many infections, however, require prolonged high-dose therapy for resolution. The following study describes two cases of aplastic anemia and sepsis associated with intermittent, chronic (17-25 days), high-dose (25-30 mg/kg, b.i.d., per os) TMP-SDZ therapy recommended for the treatment of pyoderma.(4-7)

Neonates are very susceptible to varicella, which usually causes high mortality and morbidity rates among that age group. We analyzed the prognosis and complications of neonates with varicella in a retrospective study that assessed the clinical features, laboratory data, and clinical outcomes of twelve neonates who either had the illness or who were at risk. Based on exposure history, twelve babies were separated into prenatal and postnatal infection groups. Seven cases were categorized as having prenatal infections and five had postnatal varicella infection. Results showed that the major complications in the prenatal infection group included three cases of hepatitis, two of pneumonia, one of pyoderma and one of sepsis. The presence of fever was a good indicator for predicting complications among the prenatal infection group. These complications were not found in the postnatal infection group. We found that prenatal varicella infections appear to have a higher visceral complication rate. However, our patients had a much lower mortality rate than those reported in previous studies. This may be attributed to the administration of acyclovir after delivery.

X-linked agammaglobulinemia (XLA) is a primary immunodeficiency caused by mutations in the gene for Bruton tyrosine kinase (BTK) that result in the deficient development of B lymphocytes and hypogammaglobulinemia. Because the disorder is uncommon, no single institution has had sufficient numbers of patients to develop a comprehensive clinical picture of the disorder. Accordingly, a national registry of United States residents with XLA was established in 1999 to provide an updated clinical view of the disorder in a large cohort of patients. A total of 201 patients were registered by 66 physicians. The estimated birth rate for the 10-year period of 1988-1997 was 1/379,000. Infection was the most common initial clinical presentation (85%), followed by a positive family history (41%) and neutropenia (11%). Although the average age of diagnosis was younger in patients with a positive family history (mean, 2.59 yr) than in patients with a negative family history (mean, 5.37 yr) (p < 0.001), only 34.5% of patients with a positive family history at the time of their birth were diagnosed before clinical symptoms developed-that is, based on family history alone. Seventy percent of patients had at least 1 episode of otitis, 62% at least 1 episode of pneumonia, 60% at least 1 episode of sinusitis, 23% at least 1 episode of chronic/recurrent diarrhea, 21% at least 1 episode of conjunctivitis, 18% at least 1 episode of pyoderma and/or cellulitis, 11% at least 1 episode of meningitis/encephalitis, 10% at least 1 episode of sepsis, 8% at least 1 episode of septic arthritis, 6% at least 1 episode of hepatitis, and 3% at least 1 episode of osteomyelitis. Fourteen of 201 (6.9%) patients were dead at the time they were entered in the Registry. However, in a prospective 4 /4-year follow-up of living patients, only 3/80 (3.75%) patients died. Causes of death included disseminated enterovirus infection (n = 6), pulmonary insufficiency (n = 5), adenovirus infection (n = 1), sepsis (n = 1), acquired immunodeficiency disease syndrome (AIDS) (n = 1), myocarditis (n = 1), hepatitis (n = 2), and stem cell transplantation (n = 1).

X-linked agammaglobulinemia (XLA) is a primary immunodeficiency characterized by a failure to generate immunoglobulins of all isotypes due to the absence of mature B cells and plasma cells, secondary to mutations in the Bruton's tyrosine kinase (Btk) gene. We report six patients with XLA, confirmed by mutation analysis, from northern Thailand. The mean age of onset was 2.5 years and the mean age at diagnosis was 7.3 years. All patients had a history of otitis media, pneumonia and arthritis at the time of diagnosis, five patients had developed bronchiectasis and 3 patients septicemia. Other infections reported included sinusitis (5/6), pericarditis (1/6), meningitis (1/6) and pyoderma (1/6). Haemophilus influenzae, Streptococcus pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus were isolated on multiple occasions. One patient died of sepsis at the age of 16 years. These observations demonstrate that early diagnosis and treatment can improve prognosis and quality of life.

Scabies is a worldwide disease and a major public health problem in many developing countries, related primarily to poverty and overcrowding. In remote Aboriginal communities in northern Australia, prevalences of up to 50% among children have been described, despite the availability of effective chemotherapy. Sarcoptic mange is also an important veterinary disease engendering significant morbidity and mortality in wild, domestic, and farmed animals. Scabies is caused by the ectoparasitic mite Sarcoptes scabiei burrowing into the host epidermis. Clinical symptoms include intensely itchy lesions that often are a precursor to secondary bacterial pyoderma, septicemia, and, in humans, poststreptococcal glomerulonephritis. Although diagnosed scabies cases can be successfully treated, the rash of the primary infestation takes 4 to 6 weeks to develop, and thus, transmission to others often occurs prior to therapy. In humans, the symptoms of scabies infestations can mimic other dermatological skin diseases, and traditional tests to diagnose scabies are less than 50% accurate. To aid early identification of disease and thus treatment, a simple, cheap, sensitive, and specific test for routine diagnosis of active scabies is essential. Recent developments leading to the expression and purification of S. scabiei recombinant antigens have identified a number of molecules with diagnostic potential, and current studies include the investigation and assessment of the accuracy of these recombinant proteins in identifying antibodies in individuals with active scabies and in differentiating those with past exposure. Early identification of disease will enable selective treatment of those affected, reduce transmission and the requirement for mass treatment, limit the potential for escalating mite resistance, and provide another means of controlling scabies in populations in areas of endemicity.

Fever is defined as a rectal temperature greater than 38.0 degrees C (>100.4 degrees F). A recently documented fever at home should be considered the same as a fever in the ED and should be managed similarly. All febrile infants younger than 28 days should receive a "full sepsis workup" and be admitted for parenteral antibiotic therapy. Clinical and laboratory criteria can be used to identify a low-risk population of febrile infants aged 1 to 4 months who have not received 2 doses of conjugate vaccines for bacterial meningitis. Children with sickle cell disease are at high risk and require special evaluation. MRSA infections are now common and should be considered in all patients with pyoderma, severe pneumonia, and catheter-related sepsis. HSV infection of the CNS should be considered whenever a patient has altered mental status and CSF findings are not diagnostic of bacterial meningitis. Fever rarely represents life-threatening pathology; however, a handful of less common serious causes of pediatric fever exist with the potential for morbidity and mortality.
