Communication between physicians and with patients suffering from breast cancer

BACKGROUND: The communication between GP and specialists is vital for the patient suffering from breast cancer. OBJECTIVES: The aim of this study was to investigate (i) the speed and type of communication between GPs, specialists and patients with breast cancer, and (ii) the problems that GPs encounter in the communication with specialists concerning these patients. METHOD: In April 1995, 246 Dutch GPs from the Zwolle region (600 000 inhabitants) were invited to complete a questionnaire, using the information from the medical record and focusing on the last patient consulted with a confirmed diagnosis of breast cancer. RESULTS: Valid replies were received from 150 (61 %) GPs. The median period between initial referral date and receipt of the definite diagnosis from the surgeon was 4 weeks. After the patient's first appointment with the surgeon, the GPs received reports for 24% of the patients within 3 days; for 31% within 3-7 days; and for 16% of the patients after more than 2 weeks. After the first consultation between patient and surgeon, 68 (45%) of the 150 GPs reported that the patient contacted them; at this stage only 30 (20%) of these GPs had received a report from the surgeon. Thirty-one (21%) GPs did not contact the patient after receival of the definite diagnosis. GPs stated that the communication on patients with breast cancer is too slow (49%), or not frequent enough (25%); 25% of GPs found that the distribution of tasks between them and the specialists are not well described. CONCLUSION: In the diagnostic stage of breast cancer the communication between GPs, specialists and patients varies widely, is too slow and is incomplete. An effect of this unsatisfactory communication is that the patient herself is the messenger of the bad news.      

A randomized, double-blind study to assess the efficacy of addition of tetracycline to triamcinolone acetonide in the treatment of moderate to severe atopic dermatitis

Objective To assess the efficacy of tetracycline in triamcinolone acetonide ointment compared with triamcinolone acetonide ointment in patients with moderate to severe atopic dermatitis. Design Randomised, double‐blind parallel group study of 8 weeks’ duration. Setting Outpatient clinic in a university hospital. Participants Forty‐four adult patients with moderate to severe atopic dermatitis (objective SCORAD > 25). Interventions Initial phase (2 weeks): 3% tetracycline 0.1% triamcinolone acetonide vs. 0.1% triamcinolone acetonide twice daily all over the body. Maintenance phase (6 weeks) 0.1% triamcinolone acetonide once daily for 2 weeks, followed by every other day for 2 weeks. In the last 2 weeks, two applications a week were done. An emollient was used additionally once daily. Main outcome measures Primary outcomes were the disease severity scores assessed by objective SCORAD and SASSAD at week 2. Secondary outcomes were the objective SCORAD and SASSAD at weeks 4 and 8, and Staphylococcus aureus colonization at weeks 0 and 2. Results No significant differences in disease severity outcomes were found between the two groups. Both groups showed clinically relevant improvements in disease severity compared with baseline at weeks 2 and 4. At week 8, there was some worsening in disease severity in both groups, but the disease severity was still significantly lower than at the beginning of the study. Improvement of bacterial colonization was seen in 14 (63.6%) out of the 22 patients in the 3% tetracycline 0.1% triamcinolone acetonide group and in 5 (22.7%) out of the 22 patients in the 0.1% triamcinolone acetonide group. Conclusion The addition of tetracycline was effective on skin colonization by S. aureus but did in our patients with atopic dermatitis not result in a significantly different improvement compared with the group treated without tetracycline.     

Periodontal disease and systemic health: current status

The relationship between poor oral health and systemic diseases has been increasingly recognized over the past two decades. Indeed, the clichés "You cannot have good general health without good oral health", "The mouth is part of the body" and "Floss or die", are gaining an increasing momentum. A large number of epidemiological studies have now linked poor oral health with cardiovascular diseases, poor glycaemic control in diabetics, low birthweight preterm babies and a variety of other conditions. The majority have shown an association, although not always strong. As a result, a number of meta-analyses have been conducted and have confirmed the associations and at the same time cautioned that further studies are required, particularly with regard to the effect of periodontal treatment in reducing risk. A number of biologically plausible mechanisms have been put forward to explain the association and there is accumulating evidence in support of them, although at this stage, insufficient to establish causality. Nevertheless, the relationship between poor oral health and systemic diseases has become a significant issue, such that adult oral health can no longer be ignored in overall health strategies. This review provides an update on current understanding of the contribution of poor oral health to systemic diseases, the possible mechanisms involved and the relevance of this for general dental practitioners.     

The Geneva prognostic score and mortality in patients diagnosed with pulmonary embolism by CT pulmonary angiogram

This study prospectively evaluates whether a previously established adverse outcome score (the Geneva prognostic score) predicts 3 and 12‐month overall mortality among the patients diagnosed with pulmonary embolism (PE) by a CT pulmonary angiogram (CTPA). Five hundred twenty‐three consecutive patients who had CTPA for suspected PE were recruited prospectively from March 2003 to October 2004. The Geneva prognostic score was calculated for all patients. Twelve‐month follow up was completed in all patients in December 2005. There were 105 patients diagnosed with PE. The mean score was 2.71 (standard deviation (SD) 1.25) for those patients who had died (n = 7) and 1.14 (SD 1.19) for those patients who were alive (n = 98) at 3‐month follow up (P < 0.001). The mean scores were 2.69 (SD 0.95) for those who had died (n = 13) and 1.04 (SD 1.15) for those patients who were alive (n = 92) at 12‐month follow up (P < 0.001). At 3‐month follow up, among the 88 patients with a score of 2 or less, three patients (3.4%) died and among 17 patients with a score of greater than 2, four patients (23.5%) died (P = 0.01). At 12‐month follow up, five patients (5.7%) with a score of 2 or less died and eight patients (47.1%) with a score of three or more died (P < 0.0001). The Geneva prognostic score stratifies patients with low and high risk for overall mortality at 3 and 12 months among patients diagnosed with PE by CTPA.     

Effect of slice thickness on liver lesion detection and characterisation by multidetector CT

The purpose of our study was to compare the effectiveness of 3.2 mm, 5 mm and 7.5 mm slice thicknesses in the detection and characterisation of liver lesions found on CT in patients with known or suspected malignant disease. 110 patients underwent portal phase imaging using four-slice MDCT. Two blinded observers independently read hard copy images at each slice thickness. The size and location of each lesion detected was recorded by each observer on a diagram of liver segmental anatomy. Each lesion was characterised as benign, malignant or indeterminate in nature. A diagnostic confidence score was allocated for each lesion on a scale of 1–4. The pathology or behaviour of lesions was assessed using surgery with intra-operative ultrasound (IOUS) and histology, or interval imaging with MRI, CT, or sonography. 294 lesions were detected, 64 (22%) of which were malignant. Both observers detected significantly more lesions on the 3.2 mm versus 7.5 mm slice thickness (p < 0.0001). Both observers detected more malignant lesions on 3.2 mm and 5 mm slice thicknesses versus 7.5 mm. As slice thickness decreased there was a significant increase in the sensitivity of malignant lesion detection for observer 1 (p < 0.001) and borderline significance for observer 2 (p = 0.07). As slice thickness decreased the proportion of lesions characterised as indeterminate by both observers fell. With thinner slices, both detection and characterisation of liver lesions were improved. A slice thickness no greater than 5 mm should be used to maximise both detection and correct characterisation of liver lesions.     

Enterotoxigenic Escherichia coli colonization factor types collected from 1997 to 2001 in US military personnel during operation Bright Star in northern Egypt

Operation Bright Star (OBS) is a biennial, multinational exercise in Egypt involving 15000 US troops. Consistent with past observations in deployed troops, diarrhea is the most significant cause of morbidity. Focused efforts are ongoing to develop vaccines against the most common pathogens affecting our troops. As part of these efforts, diarrhea surveillance was conducted during OBS to monitor pathogens associated with illness and to identify new vaccine targets. A retrospective review was conducted of prior studies with similar methods. Soldiers with diarrhea presenting to the OBS clinic provided a stool sample that was inoculated into Carey-Blair transport media. Within 3 days, the Cary-Blair tubes were transported to the Naval Medical Research Unit no. 3 in Cairo where bacterial culture was performed. As part of the evaluation, 5 Escherichia coli-like colonies were collected and tested for toxin production using the GM1-ELISA. Toxin-positive isolates were further tested for colonization factors (CF) by a dot-blot assay using a standardized panel of monoclonal antibodies against CFA/I, CS1-CS7, CS17, CS8 (CFA/III), CS12 (PCFO159), and CS14 (PCFO166). Enterotoxigenic E. coli (ETEC) was the most frequently isolated pathogen during each OBS from which data were collected. The rate of ETEC-associated diarrhea ranged from 22% to 58%. Over time, there were dramatic shifts in the frequency and distribution of CFs. Over the 5 years of study, an increasing number of ETEC isolates had no known CF identified, and in 2001, only 40% of ETEC was associated with known CFs. The most commonly identified CF was CS6. Diarrheal disease, particularly ETEC, continues to be a common malady among US military personnel deployed to Egypt. We have identified ETEC CF types, especially CS6, which should be considered potential vaccine candidates. However, despite intensive testing, CFs could not be identified in most of the ETEC isolated, highlighting the need for further studies to identify novel CFs and alternative vaccine targets.
