Roentgenographic findings of bilateral interstitial involvement without segmental consolidation and with regional lymphadenitis, when occurs after infancy, are always suggestive of pneumonia caused by Mycoplasma pneumoniae, as this is one of the most frequent typis of pneumonia in children. M. pneumoniae can be presumed from the discrepancy between the extensive roentgenographic findings and the generally good condition of the patient. Before therapy is decided upon it is important to know what the etiology is.

The results of serotyping of forty-six strains of pneumococci isolated from children aged 3/12 to 14 9/12 years and diagnosed as having pneumonia, meningitis, primary peritonitis, otitis media, lymphadenitis, osteomyelitis, bacteraemia and conjunctivitis are presented. The results of serotyping and the frequency distribution of the detected serotypes were compared to the particular diagnoses established and the age at which the subjects involved had become ill. Questions of epidemiology and possibilities of immunoprophylaxis are discussed. Finally, the occurrence of pneumococci that are resistant to antibiotic agents are discussed since an isolated strain was found to show reduced susceptibility to penicillin G.

A newly developed cephalosporin, cefixime (CFIX), was evaluated clinically in 35 pediatric patients. A pharmacokinetic study was also performed with 11 patients. CFIX was administered as granules. The pharmacokinetic study was conducted in 11 patients, each of 6 patients was given CFIX at a dose of 3 mg/kg and each of the remaining patients was given CFIX at 6 mg/kg. Serum concentrations of CFIX were measured at 2, 4, 6, 8 and 12 hours after dosing. Urinary concentrations of CFIX were measured for periods of 0-6 and 6-12 hours after dosing. CFIX was assayed by the disk method using E. coli ATCC 39188 as the test organism. The clinical evaluation was conducted in 35 children including 5 patients of acute tonsillitis, 10 of acute lacunar tonsillitis, 1 of purulent lymphadenitis, 1 of scarlet fever, 8 of acute bronchitis, 5 of pneumonia, 3 of urinary tract infections and 1 of paratyphoid B. One additional patient was included only in the evaluation of safety since he was suffering from Mycoplasma pneumonia. the patients were from 4 months to 8 years 2 months old and 11 of them were inpatients. Daily doses were from 6.0 to 13.5 mg/kg. After CFIX administration in doses of 3 mg/kg and 6 mg/kg, peak serum concentrations were 1.75 and 3.36 micrograms/ml, half-lives were 2.65 and 2.86 hours and urinary excretions rates up to 12 hours after dosing were 16.1 and 12.4%, respectively. Serum concentrations were dose dependent and the half-life was fairly long compared with other known oral cephalosporins. Clinical efficacies of CFIX in 34 patients were "excellent" in 25 children, "good" in 8 and "poor" in 1 with effectiveness rate of 97.1%. Twenty-two strains of causative organisms, including 6 strains of S. aureus, 3 of S. pyogenes, 2 of S. pneumoniae, 3 of E. coli, 5 of H. influenzae, 2 of H. parainfluenzae and 1 of S. paratyphi B, were isolated. After treatment all strains except 2 strains of S. aureus (one was unknown and the other was decreased), 1 strain of S. pneumoniae (unknown) and 1 strain of H. influenzae (unknown) were successfully eradicated but S. paratyphi B was proved again in feces 9 days after treatment. No adverse reaction was observed. Among 18 children who went through laboratory test, however, an elevation of eosinophile and elevations of GOT and GPT were observed in 2 children and 1 child, respectively.

Fundamental and clinical studies were carried out on cefixime (CFIX) 5% granules, and the results are summarized below. Antimicrobial activity Antimicrobial activities of CFIX, cefaclor, cefroxadine, cephalexin and amoxicillin (AMPC) were studied against clinical isolates. CFIX showed greater activities than all the other antibiotics against E. coli, K. pneumoniae, H. influenzae, P. mirabilis, E. cloacae and S. marcescens, but it was slightly less active than AMPC against S. pyogenes. Absorption and excretion Serum concentrations and urinary excretions of CFIX were determined following single or repeated oral administration. In 8 patients given single dose of CFIX 1.5 or 3.0 mg/kg, mean serum concentrations were 1.27 and 1.09 micrograms/ml at 2 hours, 1.27 and 1.35 micrograms/ml at 4 hours, 0.85 and 1.10 micrograms/ml at 6 hours, 0.17 and 0.24 micrograms/ml 12 hours after administration, respectively. Mean serum half-lives were 2.54 hours for the dose of 1.5 mg/kg and 2.60 hours for 3.0 mg/kg. Urinary recovery rates in the 12-hours urine varied 6.7 to 33.6%, with an average of 13.5%. In 3 patients given a repeated dose of CFIX 3.0 or 5.6 mg/kg b.i.d., the serum concentrations were 0.23-1.01 micrograms/ml at 0 hour, 1.91-2.80 micrograms/ml at 2-4 hours and 1.13-2.07 micrograms/ml at 6-8 hours after administration. Clinical study The CFIX was given orally by mainly b.i.d. at a daily dose of 4.4-11.6 mg/kg for 4-15 days to a total of 33 patients consisting of 3 patients with pneumonia, 3 with bronchitis, 9 with tonsillitis, 15 with UTI, one each with scarlet fever, lymphadenitis and colitis. Clinical responses were excellent in 24 patients, good in 8 and fair in 1, with an effectiveness rate of 97.0%. All of the 21 bacterial isolates examined were eradicated after CFIX treatments including 3 beta-lactamase producing strains. No side effects of abnormal laboratory findings were observed in these patients.

Cefminox (CMNX, MT-141), a newly developed injectable cephem antibiotic, was administered intravenously as one shot injection at 3 different dosages of 10, 20 and 40 mg/kg to 9 children; for each dose level 3 children were used. In these children serum and urinary concentrations as well as recovery rates were determined. In addition, in order to determine clinical and bacteriological efficacies of CMNX, it was used in the treatment of 37 cases of various infections consisting of 2 cases of acute tonsillitis, 1 case of acute tonsillitis associated with otitis media, 1 case of acute bronchitis, 1 case of chronic bronchitis, 20 cases of pneumonia, 1 case of pneumonia associated with otitis media, 8 cases of urinary tract infections, 2 cases of purulent lymphadenitis and 1 case of gluteal abscess. The drug was administered intravenously as one shot injection at a mean daily dosage of 76.6 mg/kg, in 4 divided doses in most cases, for a mean period of 6 days. Finally, in 43 cases added of 6 drop out cases which were included in analysis of efficacy side effects and abnormal laboratory findings were examined. The following results were obtained. In 9 cases, which received CMNX at 3 different dosages of 10, 20 and 40 mg/kg for 3 cases each intravenously as one shot injection, mean serum concentrations reached the peaks of 109.4, 218.1 and 357.1 mcg/ml at 5 minutes after injection, respectively, showing dose response relation. The mean half-lives were 1.74, 1.62 and 1.84 hours, respectively. The mean concentrations of CMNX in urine in the same cases as used for determinations of serum concentrations were highest during the 0 approximately 2 hours period, reaching 1,582, 3,304 and 4,618 mcg/ml at the respective doses. The mean recoveries within the first 6 hours were 82.8, 69.8 and 81.3%, the rate for 20 mg/kg group being lower than those obtained for the other groups. This is possibly due to 1 case which showed unusually low recovery rate of 44.4%. When this case is excluded, the recovery rates became similar for all groups. As to clinical results, responses rated as good or higher were obtained for 91.9% of the cases (34 cases/37 cases), with high efficacy rate. No side effects were seen in 43 cases included of drop out cases.(ABSTRACT TRUNCATED AT 400 WORDS)

Clinical studies were performed as follows on aspoxicillin (ASPC), a new semisynthetic penicillin. ASPC was intravenously given to 12 patients in doses of 57.7-129.0 mg/kg on average) t.i.d. or q.i.d. for 4-7 days (5.7 days on average): 9 with pneumonia, 1 with tonsillitis, 1 with purulent lymphadenitis and 1 with urinary tract infection. The overall efficacy rate was 83.3%, i.e. efficacy was excellent in 8 (66.7%), good in 2 (16.7%), fair in 1 (8.3%) and poor in 1 (8.3%). Bacteriological efficacy was excellent, i.e. 6 of the 6 strains disappeared. No clinical side effects were observed during treatment. Laboratory abnormalities were observed in 3 cases, slight elevation of GOT in 1, slight elevations of GOT and GPT in 1 and mild eosinophilia in 1. The above results suggest that ASPC is an useful antibiotic for treating pediatric bacterial infections.

Cefmenoxime, an investigational semisynthetic cephalosporin, was evaluated in 18 pediatric patients with a variety of infections. There were seven patients with urinary tract infections, two with wound infections, two with osteomyelitis, two with abscess infections, one with cervical adenitis, one with hidradenitis, one with pneumonia and sepsis, one with periorbital cellulitis, and one with ventriculitis. A total of 16 (88%) patients had a satisfactory clinical response demonstrated by improvement in clinical signs and symptoms. A total of 12 (67%) patients demonstrated eradication of their infecting organisms. Of the pathogens isolated in these patients, 16 isolates were susceptible to cefmenoxime. One patient developed a generalized urticarial rash that resolved within 24 h after cessation of cefmenoxime therapy. Mean peak level in serum after intravenous infusion was 55 micrograms/ml.

Interleukin-2 (IL-2), a T cell derived lymphokine, acts in nonspecific hormone-like fashion to maintain proliferation of activated lymphocytes in vitro and is believed to play a key role in cell-mediated immune function in vivo. The parameters of induction and assay of factors with IL-2 activity were examined in a group of clinically normal sheep seronegative for antibodies to ovine progressive pneumonia virus (OPPV-). Supernatants from cultures of Concanavalin A (Con A) stimulated mononuclear leukocytes (ML) derived from peripheral blood and lymph nodes contained factors with the capacity to maintain continued proliferation in Con A stimulated lymphoblasts. This activity was localized by gel chromatography to fractions containing proteins of 17,000-20,000 daltons. In a group of sheep seropositive for antibodies to OPPV (OPPV+), decreased levels of IL-2 activity were found in ML culture supernatants derived from the posterior mediastinal lymph nodes of sheep with clinical and pathological evidence of OPP, when compared to OPPV+ sheep with no lesions and sheep with visceral caseous lymphadenitis. This decrease in IL-2 activity appeared not to be associated directly with levels of prostaglandin E2 in these supernatants. These findings may correlate with virus induced alterations in cell mediated immune function in lymphoproliferative lesions of OPP.

Imipenem is the first of a new class of beta-lactam antimicrobial agents with potent in vitro activity against most bacterial pathogens that cause infections in children. We studied, prospectively, the clinical efficacy and toxicity of imipenem/cilastatin in 40 children with proved or suspected bacterial infection. A dose of 100 mg/kg/day of imipenem was given to children younger than 3 years of age, while children older than 3 years of age received 60 mg/kg/day. Twenty-nine organisms were isolated from 26 patients. Infections treated included cellulitis, osteomyelitis, septic arthritis, lymphadenitis, renal infections, wound infections, and pneumonia. Bacteria isolated included Staphylococcus aureus, Streptococcus pyogenes, Haemophilus influenzae, and Pseudomonas aeruginosa. All patients responded favorably to treatment, with defervescence and improvement of symptoms. All of the infecting bacteria were susceptible to imipenem. Imipenem/cilastatin was well tolerated, with no serious side effects, and appeared to be an effective and safe antimicrobial agent in the treatment of the population studied.

We review the cases of 19 successfully treated plague patients, with emphasis on the clinical and epidemiologic features of the disease. Proper staining and culturing of bubo aspirates; prompt institution of streptomycin, chloramphenicol or tetracycline therapy in presumptive cases, and supportive care are the crucial factors in the treatment of plague. This disease should be considered in patients in a toxic condition who have lymphadenitis, pneumonia or septic shock and who have been in endemic areas within the past ten days.
