OBJECTIVE The aim of this study was to provide a comprehensive benchmark of 30-day ventriculoperitoneal(VP)shunt failure rates for a single institution over a 5-year study period for both adult and pediatric patients,to compare this with the results in previously published literature,and to establish factors associated with shunt failure.METHODS A retrospective database search was undertaken to identify all VP shunt operations performed in a single,regional neurosurgical unit during a 5-year period.Data were collected regarding patient age,sex,origin of hydrocephalus,and whether the shunt was a primary or secondary shunt.Operative notes were used to ascertain the type of valve inserted,which components of the shunt were adjusted/replaced(in revision cases),level of seniority of the most senior surgeon who participated in the operation,and number of surgeons involved in the operation.Where appropriate and where available,postoperative imaging was assessed for grade of shunt placement,using a recognized grading system.Univariate and multivariate models were used to establish factors associated with early(30-day)shunt failure.RESULTS Six hundred eighty-three VP shunt operations were performed,of which 321 were pediatric and 362 were adult.The median duration of postoperative follow-up for nonfailed shunts(excluding deaths)was 1263 days(range 525-2226 days).The pediatric 30-day shunt failure rates in the authors'institution were 8.8%for primary shunts and 23.4%for revisions.In adults,the 30-day shunt failure rates are 17.7%for primary shunts and 25.6%for revisions.In pediatric procedures,the number of surgeons involved in the operating theater was significantly associated with shunt failure rate.In adults,the origin of hydrocephalus was a statistically significant variable.Primary shunts lasted longer than revision shunts,irrespective of patient age.CONCLUSIONS A benchmark of 30-day failures is presented and is consistent with current national databases and previously published data by other groups.The number of surgeons involved in shunt operations and the origin of the patient's hydrocephalus should be described in future studies and should be controlled for in any prospective work.The choice of shunt valve was not a significant predictor of shunt failure.Most previous studies on shunts have concentrated on primary shunts,but the high rate of early shunt failure in revision cases(in both adults and children)is perhaps where future research efforts should be concentrated. 相似文献

Background
The extent to which GPs serve as a reservoir for antibiotic-resistant Staphylococcus aureus is unknown and not well studied.Aim
To determine the prevalence of nasal S. aureus carriage among GPs in the Netherlands, as well as the antimicrobial resistance and the genotypes of isolated S. aureus.Design of study
Observational, point-prevalence, and cross-sectional study.Setting
GPs attending the annual conference of the Dutch College of General Practitioners in 2006.Method
Nasal swabs were randomly taken from 395 GPs and analysed for the presence of S. aureus. Antimicrobial susceptibility was determined by a microbroth dilution method and the genotypes by spa typing, which was associated with multilocus sequence typing.Results
Of the GPs, 129/395 (33%; 95% confidence interval [CI] = 28 to 37%) were carriers of S. aureus. No meticillin-resistant S. aureus (MRSA) was found. Resistance was observed to penicillin (71%; 95% CI = 63 to 79%), fusidic acid (7%; 95% CI = 3 to 13%), and clarithromycin (6%; 95% CI = 3 to 12%). In 72% of the isolates, an MRSA-related genotype of S. aureus was found.Conclusion
The low antibiotic resistance found among S. aureus of GPs suggests that GPs are not a reservoir of antibiotic-resistant S. aureus strains. The relatively high resistance to fusidic acid, which has not previously been described in the Netherlands and is mostly because of antibiotic use, suggests that patients infect GPs and not the other way round. GPs may be at risk for nasal carriage of S. aureus with an MRSA-related genotype. 相似文献107.

Abstract – Objectives: Several studies have been conducted on the prevalence of hyposalivation in older adults but no population‐based studies in younger adults. Therefore, our aims were to determine the prevalence of very low and low unstimulated (UWSFR) and stimulated (SWSFR) whole salivary flow rates in different age groups between 20 and 69 years, and to analyse the relationship between hyposalivation, subjective oral dryness and predictors of reduced flow rate. Methods: A randomized and stratified cross‐sectional study including 1427 dental patients was conducted. UWSFR and SWSFR were measured, numbers of remaining teeth recorded and a questionnaire answered regarding subjective oral dryness, general diseases, use of drugs, body mass index (BMI) and use of tobacco. Results: The prevalence of very low (<0.1 ml/min) and low (0.10–0.19 ml/min) UWSFR was similar for different age groups up to 50 years, ranging between 10.9–17.8% and 17.3–22.7%, respectively. The prevalence of very low UWSFR was significantly higher for women aged 50–69 years than for younger women. For men, prevalence of very low UWSFR was higher at 60–69 years. The prevalence of very low (<0.7 ml/min) and low (0.70 – 0.99 ml/min) SWSFR was between 0–5.5% and 0.8–8.2%, respectively, for the different age groups 20–69 years. Multiple logistic regression revealed that age above 50 years, female gender, having fewer than 20 teeth, and taking xerogenic drugs significantly increased the risk of very low UWSFR. For very low SWSFR, only having fewer than 20 teeth and taking more than two drugs were significant. In the younger individuals (<50 years) only BMI > 25 for very low UWSFR and diagnosed disease for very low SWSFR were found significant. In this younger subset, female gender combined with having fewer than 27 teeth was significant for low UWSFR. Conclusions: Hyposalivation is prevalent in younger adults, among whom it is associated with diagnosed disease and high BMI, while after age 50 years it is associated with medication. It is also associated with gender and with fewer remaining teeth. 相似文献

Objectives
The aim of this study was to describe and analyse the medical and social prognoses of patients with non-specific building-related symptoms.Methods
A follow-up questionnaire focusing on current medical and social status, care, treatment, other actions taken and personality traits was sent to 239 patients with non-specific building-related symptoms assessed during the period between1986 and 1998 at University Hospital in Umeå, Sweden. The response rate was 79%.Results
Fatigue, irritation of the eyes, and facial erythema were the most common weekly symptoms reported at follow-up. As females constituted 92% of the respondents, statistical analyses were restricted to women. The level and severity of symptoms decreased over time, although nearly half of the patients claimed that symptoms were more or less unchanged after 7 years or more, despite actions taken. Twenty-five percent of the patients were on the sick-list, and 20% drew disability pension due to persistent symptoms at follow-up. The risk of having no work capabilities at follow-up was significantly increased if the time from onset to first visit at the hospital clinic was more than 1 year. This risk was also significantly higher if the patient at the first visit had five or more symptoms. All risk assessments were adjusted for length of follow-up. Symptoms were often aggravated by different situations in everyday life.Conclusions
Long-lasting symptoms aggravated by environmental factors exist within this group of patients. The results support that early and comprehensive measures for rehabilitation are essential for the patients.109.
In previous study we found that clavicular lesions in chronic recurrent multifocal osteomyelitis (CRMO) in young patients was associated with palmoplantar pustulosis (PPP). In this work the relationship between sternoclavicular lesions and PPP was studied in a group of adult patients. The sternoclavicular region of 52 patients with PPP and 25 control persons was examined by tomography. Among the PPP patients there were inflammatory lesions in the sternal synchondroses in 3 patients. There were no such lesions in the controls. In this unselected population of adult patients there was thus no definite association between PPP and sterno-clavicular lesions. In young patients on the other hand, CRMO with clavicular lesions may be another, probably noninfectious, cause of PPP. 相似文献
