Coagulase-negative staphylococci cause about 5% of native-valve
endocarditis. Staphylococcus lugdunensis, a recently-described species of
coagulase-negative staphylococci, has been reported to cause destructive
native-valve endocarditis with a high mortality. We report four consecutive
cases of definite Staphylococcus lugdunensis native- valve endocarditis by
the Duke criteria over a 4-year period. All patients required urgent aortic
valve replacement 1-5 days after admission, and recovered. An intriguing,
aspect in the presentation of these patients was a history of vasectomy and
inguinal skin breaks in the immediate period preceding the occurrence of
endocarditis.

Registered Nurses (RN's) caring for the critically ill, require a wide range of specialised skills and knowledge. Assessing knowledge of RN's within Intensive Care Units (ICU's) is imperative if we are to ensure that patients are afforded quality care. The aim of this study was to evaluate existing knowledge of the RN's working in the ICU of a major teaching hospital using the Basic Knowledge Assessment Tool (BKAT).Overall mean test scores of 78% were encouraging. Knowledge gaps were evident in gastrointestinal and endocrine disorders. Significantly higher scores were obtained by RN's trained in the hospital based system (p=0.02) and those possessing ICU qualifications (p=0.01). There were no differences in scores according to age and length of ICU experience. Registered nurses scored badly in a number of questions, which highlighted some problems in the terminology used in the BKAT. 相似文献

A case of leaking mycotic abdominal aortic aneurysm is reported, with a brief review of the literature. A 58 year old female presented with shoulder and abdominal pain associated with diarrhoea, vomiting and fever with leucocytosis. Computed tomography of the abdomen showed pooling of contrast in the retroperitoneum anterior to a non-dilated abdominal aorta. There was considerable retroperitoneal blood accumulating in a mass-like lesion in the right lower abdomen and pelvis obstructing the right renal collecting system. Laparotomy revealed a 4 cm diameter saccular aneurysm of the abdominal aorta, with a 1 cm diameter neck. Culture of the thrombus grew Streptococcus pyogenes. 相似文献

Mouse mutants carrying deletions that remove the genes mutated in Coffin-Lowry syndrome and lactic acidosis 总被引:1,自引:0,他引:1
The mouse X-linked mutants lined and stripey are associated with lethality
of affected males in utero and a striping of the coat in carrier females.
We demonstrate that the underlying mutations are nested deletions which lie
in the Phex-Amelx chromosomal segment conserved between man and mouse. The
lined deletion contains less than approximately 0.7 cM of genetic material
and includes the growth factor- regulated protein kinase gene, Rsk2.
Stripey carries a larger deletion which removes approximately 2.0 cM of
genetic material, including Rsk2 and the pyruvate dehydrogenase E1alpha
subunit gene, Pdha1 . Since Coffin-Lowry syndrome and neonatal lactic
acidosis are associated with mutations in the human homologues of Rsk2 and
Pdha1 respectively, lined and stripey provide models for gene deficiencies
in these disorders.

Aim: In this study, we determined whether outcome of preterm neonates has improved over a period of 16 years. Study design: Inborn neonates with a gestational age of 25.0–29.9 weeks were included. Patients with severe congenital malformations were excluded. Mortality and morbidity (chronic lung disease; CLD, intraventricular haemorrhage: IVH grade III or IV, cystic periventricular leukomalacia: cPVL, perforated necrotizing enterocolitis: NEC, severe retinopathy of prematurity needing surgery: ROP and cerebral palsy: CP) were compared in three periods (period 1: 1991–1996 n = 434; period 2: 1997–2001 n = 356; period 3: 2002–2006 n = 422). Results: Infant mortality decreased from 15.2% to 10.9%. CLD did not differ significantly between periods (14.1–14.8%). Perforated NEC decreased from 2.8% to 1.6%. IVH grade III and IV both remained at 5.7% in period 3, whereas cPVL decreased significantly from 4.5% to 1.6%. Cerebral palsy decreased from 5.8% to 3.5% in period 3. Two neonates in each period were in need of surgery for ROP. Conclusion: Inborn preterm patients showed an improved survival and a significant reduction in cPVL and CP. Perforated NEC showed a trend to decrease. CLD and IVH grade III and IV remain a matter of concern. 相似文献

BACKGROUND: Nurses tend to wash their hands more often than physicians, and among nonhealth care workers, women tend to wash their hands more often than men. This study examined the influence of gender on the handwashing rates of health care workers (HCWs). The null hypotheses were that there would be no intergender difference in (a) handwashing rates in HCWs across professions and (b) within professional groups. METHODS: Handwashing by nurses, physicians, wardspersons, x-ray technicians, and physiotherapists after patient contact in a critical care unit (CCU) was determined through covert observation. The gender and profession of the subjects were recorded, but their identity was not. RESULTS: Female CCU staff washed their hands significantly more often than did their male counterparts after patient contact (P =.0001). When the results were examined for the influence of profession on handwashing, significant intergender differences remained for physicians (P =.0468) and wardspersons (P =.0001). There was also a nonsignificant trend (P =.07) toward higher rates of handwashing among female x-ray technicians. There were no statistically significant intergender differences in handwashing rates among nurses (P =.7588) and physiotherapists. CONCLUSIONS: It appears that gender may influence handwashing rates in HCWs in the CCU, although this difference appears to be modified in particular professional groups. Further research should examine factors that modify handwashing rates within professional groups and in settings other than the CCU. 相似文献
