Granulocytic sarcoma (GS) is a rare localized, extramedullary tumor composed of immature cells of granulocyte series. It is capable of marked local tissue destruction. This condition can be a precursor of acute myeloid leukaemia by months or years making its diagnosis critical. Its occurrence has been described in multiple sites including skin, lymph nodes, bone, and visceral organs. It is extremely rare in the oral cavity and only 30 cases have been reported in the literature to date and often as a lump in the gingiva, palate, and extraction sockets. We describe the first reported case of GS presenting as a solitary lump in the lip and review the pertinent literature.  相似文献

Gloving reduces acquisition of vancomycin-resistant Enterococcus species (VRE) on the hands, and it should be considered for routine inpatient care, even for contact with the intact skin of patients who may be colonized with VRE. However, gloving does not completely prevent contamination of the hands, and hand washing is necessary after glove removal.  相似文献

AIMS: The aims of this review were to assess the reasons why patients were referred to a specialist dental paediatric unit and the quality of the referral letters received. MATERIAL AND METHOD: All patients referred to the paediatric consultation clinic at the Liverpool University Dental Hospital from January 2004 to July 2004 were included in the review. The reasons for their referral, as stated by the referring practitioners, were compared with the clinical findings from initial assessments in the consultation clinic and the quality of referral letters was assessed. RESULTS: Ninety-nine out of a total of 102 referrals were from general dental practitioners. Sixty were girls and 42 boys. Their mean age was 9.5 years. The commonest reason (25 patients) was for treatment under general anaesthesia. In 90 (88.2%) cases the main reason for referral stated in the letters was consistent with the findings of the clinical assessment in the consultant clinic. All 102 letters included the patient's name, address, date of birth and telephone number and 89 (87.3%) were dated. However, only 25 (24.5%) included any mention of medical history and fewer than 30% included details of any treatment provided by the referring practitioner. CONCLUSIONS: The vast majority of patients were referred for good reasons. The quality of the referral letters was generally poor. The use of a structured referral pro forma could improve the quality of the referral.  相似文献

In this short review we highlight the diagnostic challenge presented by surgical peritonitis in peritoneal dialysis patients, giving attention to etiology, clinical presentation, diagnosis, and management. Despite improvements in medical imaging and a reduction in overall rates of peritonitis in peritoneal dialysis, the mortality of surgical peritonitis has not changed in recent years and remains a challenge for the clinical team.  相似文献

Septic shock is a serious medical condition. With increased concerns about invasive techniques, a number of non-invasive and semi-invasive devices measuring cardiac output (CO) have become commercially available. The aim of the present study was to determine the accuracy, precision and trending abilities of the FloTrac and the continuous pulmonary artery catheter thermodilution technique determining CO in septic shock patients. Consecutive septic shock patients were included in two centres and CO was measured every 4 h up to 48 h by FloTrac (APCO) and by pulmonary artery catheter (PAC) using the continuous (CCO) and intermittent (ICO) technique. Forty-seven septic shock patients with 326 matched sets of APCO, CCO and ICO data were available for analysis. Bland and Altman analysis revealed a mean bias ±2 SD of 0.0 ± 2.14 L min?1 for APCO–ICO (%error = 34.5 %) and 0.23 ± 2.55 L min?1 for CCO–ICO (%error = 40.4 %). Trend analysis showed a concordance of 85 and 81 % for APCO and CCO, respectively. In contrast to CCO, APCO was influenced by systemic vascular resistance and by mean arterial pressure. In septic shock patients, APCO measurements assessed by FloTrac but also the established CCO measurements using the PAC did not meet the currently accepted statistical criteria indicating acceptable clinical performance.  相似文献
