The study consist of 134 neonatal pneumonia who under 28 days born addmitted to The Neonatal department of National Institute of Peadiatrics from December 2001 to November 2002. The out comes showed that: Positive rate: 71.15%, negative rate: 29.85%. Common isolated bacteria were negative Gram. Ampicillin, gentamycin, chloramphenicol bactrim have resistance antibiotic. The recovered treatment result: 90.3%; mortality: 9.7% in which 61.2% are fully recovered without change other antibiotic. The average treatment duration by antibiotic:13.2%

This study was aimed to assess the dissolution of 4 chloramphenicol capsule products of 4 Vietnamese pharmaceutical enterprises. The results showed that most of them have a very low drug release degree. The cause may be resulted from making capsule without making particles, too raw powder, using too much insoluble excipient, too high rate of insoluble excipient. The dissolution test should be considered an item of chloramphenicol capsule specification

Background/Objective: Haemophilus influenzae type b remains to be a significant etiology of invasive infections specially in children two months to five years old without Hib vaccination. This study was performed to compare the cure rates of ampicillin, chloramphenicol, ampicillin-chloramphenicol combination and third generation cephalosporins as initial antibiotic treatments for documented invasive Hib infections. This study may assist in formulating recommendations on empiric antimicrobial therapy. Methods: Charts of patients with invasive Hib disease confirmed either by blood culture, CSF culture and/or latex agglutination test from January 1991 to August 2010 were reviewed. Cases were classified into four groups depending on the initial antibiotic given upon admission. The four groups were compared and analyzed in terms of cure rates. Results The disease occurred predominantly in children less than two years old. Males were more frequently affected than females. All subjects were not given Hib vaccination. Cure rates were significantly different between ampicillin (33%) and chloramphenicol (89%) groups (p=0.017), and between chloramphenicol (89%) and ampicillin-chloramphenicol (39%) groups (p=0.008). However, cure rates were not significantly different when third generation cephalosporin group (62%) was compared to the other treatment groups (p>0.05). Resistance of Hib was 31% to ampicillin, while <10% to chloramphenicol and third generation cephalosporins. Conclusion: Chloramphenicol is an excellent drug for empiric therapy in highly suspected or proven cases of invasive Hib disease.

Protermycin, the first molecular synthetic of tetracycline and chloramphenicol, has been given trial in 28 patients: acute gonococcal urethritis 10, nongonococcal urethritis 7, acute cystitis 6, chancroid 1 and postoperative cases 4. The doses ranged from 300 to 600 me daily. From this study, it was found that Protermycin proved itself to be most effective in nongonococcal urethritis which could not be treated satisfactorily by other antibiotics. Of 28 cases, 25 showed good result. The remaining 3 cases failed to respond.

Haemophilus influenzae type b (Hib) is a major cause of meningitis and pneumonia in children. In Papua New Guinea (PNG) more than 20% of Hib are now resistant to chloramphenicol, and resistant Hib meningitis treated with chloramphenicol results in certain death or severe brain injury. Third-generation cephalosporins are a therapeutic option but are very expensive, while the Haemophilus influenzae type b conjugate vaccine would provide effective prevention. In a province of 380,000 people, using ceftriaxone as standard treatment for meningitis in all health facilities would only save an estimated 8 more lives per year than using chloramphenicol, and cost US dollars 1514 per additional life saved. Introduction of Hib vaccine would save, each year, 61 more lives than using chloramphenicol and 53 more lives than using ceftriaxone for meningitis treatment. The cost of a vaccination strategy for Hib meningitis would be US dollars 1216 for each of the 61 additional lives saved. Hib vaccine would be by far the most effective intervention to reduce mortality and severe neurological disability from Hib meningitis in PNG. Nationwide introduction of Hib vaccine is urgently needed, as antibiotics are now less effective in this disease than ever before.

Microorganisms are the dominant players driving the degradation and transformation of chloramphenicol (CAP) in the environment. However, little bacterial strains are able to efficiently degrade and mineralize CAP, and the CAP degrading pathways mediated by oxidative reactions remain unclear. In this study, a highly efficient CAP-degrading microbial consortium, which mainly consists of Rhodococcus (relative abundance >70%), was obtained through an enrichment process using CAP-contaminated activated sludge as the inoculum. A bacterial strain CAP-2 capable of efficiently degrading CAP was isolated from the consortium and identified as Rhodococcus sp. by 16S rRNA gene analysis. Strain CAP-2 can efficiently degrade CAP under different nutrient conditions. Based on the biotransformation characteristics of the detected metabolite p-nitrobenzoic acid and the reported metabolites p-nitrobenzaldehyde and protocatechuate by strain CAP-2, a new oxidative pathway for the degradation of CAP was proposed. The side chain of CAP was oxidized and broken to generate p-nitrobenzaldehyde, which was further oxidized to p-nitrobenzoic acid. Strain CAP-2 can be used to further study the molecular mechanism of CAP catabolism, and has the potential to be used in in situ bioremediation of CAP-contaminated environment.

In search of the best preventive measures against postoperative wound infections, the author has conducted a series of studies which preliminary results are as follows. (1) There were no postoperative secondary infections in 50 surgical cases except in one, which had undergone dacryocystorhinostomy. (2) More than one strain of microorganism were isolated from all of 20 operator's nostril, throat, and peritonsillar region. It is strongly suggested that operators and hospital workers play an important role in the cause of hospital infection. (3) Some difference in the strain of organisms isolated were noted between the countrymen and townsmen. (4) It is urged to pay particular attention to sterilization for lowere abdominal surgery. (5) Chloramphenicol exerted an sustained and excellent broadspectrum antimicrobial activity to various microorganisms.

Curvularia species is a genus of dematiaceous fungi that resides primarily in soil, and rarely causes human infections. The infection caused by Curvularia species usually occurs in immunocompromised patients, but a few reported cases have occurred in immunocompetent patients with no prior disease. A 55-year-old woman, previously in good health, complained of a dystrophic nail of the left big toe. Sampling from the lesion was made by scraping of the diseased nail plate. The specimens were examined in KOH and inoculated on slants containing Sabouraud's dextrose agar with chloramphenicol and Dermatophyte test Medium (DTM) which were incubated at room temperature. Direct microscopic examination, using KOH, showed septated hyphae. Culture on Sabouraud's dextrose agar yielded a filamentous dematiaceous fungus, which was identified as Curvularia species. This is the first case of onychomycosis as well as human infection caused by Curvularia species in Korea. ME: Curvularia species, Onychomycosis

Tsutsugamushi fever is a serious febrile disease outwardly similar to malaria and various arboviral infections. The endemic area is Asia-Pacific. This disease are generally associated with disturbed habitats favoring large populations of vector larval trombiculid mites. Therapy with tetracycline, chloramphenicol or ciprofloxacin is currently recommanded. Unfortunately these drugs is suboptimal for children and pregnant women. Recently, azithromycin has been proven to be effective in therapy of scrub typhus. There is no evidence that azithromycin causes adverse reaction to developing fetus or children. We report four cases of tsutsugamushi fever in children successfully treated with azithromycin. This is the first report describing clinical application of azithromycin to tsutsugamushi fever in Korean children.
