Reactive arthritis comprises a subgroup within infection-associated arthritides in genetically susceptible hosts. Researchers and clinicians recognize two clinical forms of reactive arthritis which occurs after genitourinary tract infection and after gastrointestinal tract infection. Chlamydia infection has been implicated as the most common agent associated with post-venereal reactive arthritis. Studies have proposed Shigella infection, Salmonella infection, or Yersinia infection as the microorganisms responsible for the post-dysenteric form. The human leukocyte antigen (HLA)-B27 antigen is the best-known predisposing factor. We report a case of HLA-B27-associated reactive arthritis after Salmonella enteritis at Pusan National University hospital.

Argulus spp, a small group of parasitic curstaceans called Branchiura, is particularly important in freshwater acquaculture. We investigated the infection of Argulus to several different species of fishes and therapy effect of masoten. Argulus japonicus was collected from Okjeong lake, Chonbuk province and experlmen-tally infected to freshwater fishes from July to August 1998. The results were as follows ; 1. The shape of a Agulus is an oval and dorsoventrally flattened, with first maxillae and second maxillae, and four pairs of legs. 2. The size of the adult stage of A japonicus was 3.2-5.0$\times$2.3-2.9mm in female and 1.5-3.1$\times$1.6-2.9mm in male. 3. In the trial of experimental infection with A japonicus to non-scaled fishes, Parasilurus asotus and Ictalurus punctalus, were infected and some of them died after severe infection. However, A japonica was not infected at all. 4. Masoten treatment for A japonicus was effective at 0.2 ppm once a day for 3 days and parasites on the surface of fishes disappeared after five days.

The resistant strains due to the extended-spectrum $\beta$-lactamase (ESBL) were susceptible to cefatrizine combined with clavulanic acid. The purpose of this study was to evaluate the in vitro and in vivo antibacterial activities of cefatrizine/clavulanic acid (CTRZ/CV) combination at a ratio of 2 : 1 in comparison with cefaclor (CCLO), cefuroxime (CRXM), cefuroxime axetil (CRXMA) and amoxicillin/clavulanic acid (AMXCCV). CTRZ/CV showed good activity against laboratory strains of gram-positive and gram-negative bacteria and exhibited excellent antibacterial activity against $\beta$-lactamase-producing strains. The bactericidal activity of CTRZ/CV was superior to that of CCLO and CRXM, and almost equal to that of AMXCCV against the $\beta$-lactamase-producing strains. The in vitro results were substantiated. by in vivo mouse experimental infection studies with $\beta$-lactamase-producing and non-producing strains. In mixed experimental infection due to $\beta$-lactamase-producing and non-producing strains, the therapeutic efficacy of CTRZ/CV was superior to that of CTRZ, CCLO, CRXMA and AMXCCV. In respiratory tract infection in mice due to Klebsiella pneumoniae EB4O, CTRZ/CV was more erective than CCLO, CRXMA and AMXCCV and also more efficacious than CCLO, CRXMA and AMXCCV in urinary tract infection in mice due to Escherichia coli EB13. These results indicate that CTRZ/CV is a useful drug for the treatment of infection caused by $\beta$-1actamase-producing strains including ESBL-producing strains.

The effect of mecadox, trade name of carbodox, in the treatment of colibacillosis and in the prevention of experimental Salmonella infection in swine was studied throughout the experimental period of four weeks using a total of 70 piglets. The results obtained are as followings. 1. Mecadox was found moderately effective as a therapeutic for colibacillosis of piglets when administered orally as pig doser or added to the feed at the ratio of 50 ppm with or without the addition of vitamin A and $D_3$. 2. In the prevention of experimental infection with Sal. choleraesuis, mecadox was found highly effective. As judged by clinical symptoms such as diarrhea and fever together with the confirmation of excretion of the causative organisms in the feces, the best result was obtained with mecadox pig doser followed by mecadox (50ppm) with vitamin A and $D_3$, and mecadox (50 ppm) without the vitamins in the descending order of effectiveness.

Purpose: This study was designed to verify effects of perineal care with aroma essential oil on urinary tract infection(UTI) in patients with indwelling urinary catheter. Method: The research design was non equivalent control group pretest-post test design. The data were collected from March to August, 2005 at C university hospital in Seoul. The subjects were 43 patients who had a indwelling catheter in neurosurgery intensive care unit(NSICU). They were assigned to two groups, 21 subjects to the experimental group and 22 subjects to the control group. The experimental group received perineal care with 3% blending essential oil for 4 days. Results: In the experimental group, white blood cells and bacteria in urine were significantly lower than control group. Bacteria in urine culture was lower in the experimental group at post test. Conclusion: Perineal care with aroma essential oil could be an effective intervention to reduce the UTI of patients in NSICU.

Purpose: This study aimed to examine the effects of extended family visiting hours in the intensive care unit (ICU). Methods: The subjects were 168 ICU patients and their family members. Two 30-minute visits a day were allowed to the control group according to current policy, while four 30-minute visits a day were allowed to the experimental group. Patients' state anxiety was measured at the first day of ICU admission, and on the third day of ICU admission patients' anxiety and family satisfaction were measured. For the infection rate, comparison was made between the experimental and control data-collecting periods. Results: The patients' state anxiety significantly decreased in the experimental group. Family satisfaction of experimental group was significantly higher than that of control group. There was no significant difference in the infection rate. Nurses positively evaluated extension of visiting hours because it could stabilize patients, reduce the number of arrangements for additional visits, and help establish trust relationship with families. Conclusion: Extended family visiting hours in the ICU reduced patients' anxiety and improved family satisfaction but had no effect on the infection rate. Extended family visiting hours in the ICU is expected to improve the quality of critical care.

Several strategies for the management of venous congestion of the nipple-areola complex (NAC) after reduction mammaplasty have been proposed. Among these, hirudotherapy represents an ancient but still effective method, even though the risk of infections related to leeches should be considered. We report a peculiar case of breast infection and sepsis after leech therapy in a patient who underwent a reduction mammaplasty. A prompt surgical debridement of the wounds and necrotic tissues associated with targeted antibiotic therapy led to a fast improvement of clinical conditions, and partial preservation of the NAC was obtained. Accurate knowledge of the clinical presentation of soft tissue infections related to leeching allows for an early diagnosis and would serve as a warning for surgeons who approach such breast cosmetic procedures.

Helicobacter pylori infection has declined over recent decades. However, its prevalence remains high, and nearly 50% of the global population has been infected. In Korea, seroprevalence has steadily decreased in adults, but the status of H. pylori infection in children is unknown. The current status or trend of H. pylori infection in children is important because it can help estimate H. pylori-related diseases including gastric cancer in later life. In this review, the authors discuss the change in H. pylori infection rate among children and adolescents based on literature reviews and our research.

Cytomegalovirus (CMV) is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID), which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS). Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at $72{^{\circ}C}$ for 5 seconds can eliminate CMV completely.

Helicobacter pylori (H. pylori) is an important bacterial pathogen that causes chronic gastritisand is associated with gastroduodenal ulcer disease, adenocarcinoma of the distal stomach, and gastricH. pylori infection associated with host agehave not been well-defined in human. To evaluate the difference in host susceptibility to infection in relationto age of acquisition of H. pylori infection, we designed an experiment involving inoculation of H. pyloriATC 43504 at different ages of Mongolian gerbils. H. pylori was inoculated at 5 weeks and 18 monthsof age, as representatives of early and late infection, respectively. Animals were sacrificed 1 week and 4weeks after challenge, and the stomach was removed from each animal for bacterial culture, histologicalexamination, and polymerase chain reaction test. 5 week-old gerbils revealed infection andmaintained continuously its infection until 4 weeks. However, old gerbils did not maintained H. pyloriinfection. These data suggest the insusceptibility of H. pylori in old Mongolian gerbils and the importanceof animal ages for successful animal experimental infection. Also, the results demonstrated that earlyinfection of H. pylori increases its host susceptibility, as compared to the case with later infection, possiblybecause of differences in host gastric mucosal factors and imunologic responses.
