Forty-seven strains of methicillin-resistant Staphylococcus aureus (MRSA) isolated from 47 patients with bacteremia were analyzed by chromosomal DNA digestion pattern using pulsed-field gel electrophoresis and evaluated for serological coagulase type, enterotoxin type, and toxic shock syndrome toxin-1 production. The mortality rate was significantly higher in the older patients (> or = 51 years of age) than in the younger patients (< or = 50 years of age) (50% vs. 4%, p = 0.0007). Methicillin-resistant Staphylococcus aureus strains of serological coagulase type II were more likely to be associated with mortality in older patients than were strains of the other types (p = 0.037).
Percentage of the outbreaks by O3:K6 Vibrio parahaemolyticus (V. p) in Aichi Prefecture Japan increased from 3% (3/86) for 1988-95 to 75% (33/44) for 1996-2001. The percentage of the sporadic diarrhea cases caused by O3:K6 V. p in a general hospital in Aichi Prefecture also increased from 0% (0/253) to 61% (135/221) during the same periods. Thermostable direct hemolysin (TDH)-positive O3:K6 were isolated from 95% (19/20) of the outbreak incidents and 100% (135/135) of the sporadic cases. Only one TRH (TDH-related hemolysin)-positive O3:K6 was isolated from one outbreak incident. Percentage of the outbreaks by O3:K6 V. p associated with the consumption of boiled shellfishes increased from 5% (6/117) for 1988-95 to 25% (15/59) for 1996-2001, in particular, boiled crabs and squillas associated outbreaks increased from 2% (2/117) to 17% (10/59) and from 2% (2/117) to 10% (6/59), respectively. From 1,548 raw sea foods sampled in the Nagoya Central Wholesale Market in Aichi Prefecture in 1995-99, one TDH-positive O3:K6 was isolated from one live squilla (1/30). Increase in the percentage of outbreaks associated with TDH-positive O3:K6 V. p after 1996 in Aichi Prefecture was revealed to correlate with the increase in the outbreaks associated with consumption of boiled sea foods, especially boiled crabs as well as squillas. Accordingly, it becomes clear that sanitary handling of these boiled foods is important to prevent outbreaks and sporadic cases of diarrhea caused by O3:K6 V. p infection.
To investigate the prevalence of attaching and effacing Escherichia coli, we examined 364 strains isolated from the feces of 9,684 patients with diarrhea at the Anjo Kosei Hospital in Japan for the presence of eaeA. Twenty-nine (8%) of the strains were eaeA positive. Of enteropathogenic E. coli (EPEC), 11 of the 87 (13%) strains were for the positive eaeA gene. The serotypes and the numbers of eaeA-positive strains among the strains tested were as follows:
From 2006 to 2009 we treated nine cases (11 toes) with pincer nail deformity of the first toe, using phenol. There were 8 women and 1 man, age range 9-81 years (mean 51). They were followed up for 7-17 months (mean 12) and all reported improvement of the pincer nail deformity and disappearance of pain from the first toes. Only one woman complained of a recurrent pincer nail deformity eight months after the first treatment, and the procedure was repeated. The mechanism of improvement is contraction of the phenolised wound away from the lateral nail fold, which gradually stretches and flattens the nail bed. We conclude that this technique is a simple and effective treatment for pincer nail deformity.
Objective: In urological operations, many endourological procedures and pre-existing urinary tract infections may cause surgical complications. It is essential to identify the risk factors for surgical site infections (SSI) and determine additional influences.
Patients and Methods:In the present retrospective investigation, a total of 324 patients who underwent open urological surgery between January 2003 and December 2007 at Anjo-Kosei Hospital were assessed for SSI along with possible associated factors. Results: Forty-four cases (13.6%) proved positive for SSIs during the surveillance period. Among these, 31 demonstrated incisional SSI and 13 demonstrated deep/organ space SSI. Greater age and body mass index, low preoperative haemoglobin levels, long preoperative hospital stay, prolonged operation time and increased blood loss during surgery were all positively associated with SSI in general. For the deep/organ space SSI cases, advanced age, low preoperative haemoglobin levels, long preoperative hospital stay and prolonged operation time were significant factors. Conclusion: This study identified several independent predictors of SSI in general, as well as deep/organ space infection, for urological open surgery at our hospital. The results provided a basis for urologists to decrease the incidence of urological SSI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
