[Physicians' knowledge on cancer pain therapy : Comparison of palliative care and prehospital emergency physicians in training]

BACKGROUND

Palliative care needs a high level of expertise. In particular, there are some potential difficulties in the treatment of patients with the symptom cancer pain (for example lack of education). In Germany, various physicians are involved in cancer pain treatment but in general palliative care patients are treated by a physician who is educated in palliative medicine. In special circumstances prehospital emergency physicians and other physicians are involved in therapy decisions in palliative care patients as well. The authors surveyed different groups of physicians in Germany about their specific knowledge of cancer pain management.

MATERIAL AND METHODS

A self-designed, standardized questionnaire (50 items) was given to palliative physicians in training (PP). The survey asked prospectively for knowledge on the World Health Organization (WHO) step ladder of cancer pain therapy. The results were retrolectively compared with an earlier investigation with the same background (emergency physicians in training EP).

RESULTS

There was a 99.5% response rate with a total of 654 respondents (PP 185, EP 469) and 461 (70.5%) of the respondents had knowledge of the WHO step ladder for the treatment of cancer pain [PP 164/185 (88.6%), EP 297/469 (63.3%), PP versus EP p < 0.001)]. The correct numbers of therapeutic levels were known by 361/461 participants [PP 151/164 (92.1%), EP 210/297 (70.7%), p < 0.001].The EPs with a professional experience less than 5 years answered statistically significantly more questions correctly (p = 0.004). Concerning the defined parameters knowledge and professional experience, there was no statistically significant difference in the group of PP.

CONCLUSIONS

The results of this study verified that the highest knowledge scores were achieved by PPs and overall, the knowledge scores showed an improvement in comparison to previous investigations. In recent years there seems to have been an improvement in education on pain treatment,for example during medical school. Whether this also leads to an improvement of patient care and the relevance of these data for the clinical practice needs to be investigated in further studies.

[Anti-p200 pemphigoid: a spectacular response to dapsone]

BACKGROUND

Types of subepidermal autoimmune bullous dermatosis (AIBD) are classified by anatomoclinical picture and target antigen. A new entity has recently been identified: anti-p200 pemphigoid.

PATIENTS AND METHODS

An 82-year-old man consulted for a profuse pruritic bullous eruption refractory to the standard treatments for bullous pemphigoid (BP). Direct immunofluorescence examination of a skin biopsy revealed linear deposits of IgG and of C3 at the dermal-epidermal junction, but Elisa screening for circulating anti-BP180 and anti-BP230 antibodies was negative. Indirect immunofluorescence (IIF) testing of cleaved skin revealed a deposit of IgG4 antibodies on the dermal side. Immunoblotting was negative for a dermal extract but showed an antibody directed against a 200-kD epidermal antigen. A diagnosis of anti-p200 pemphigoid was eventually made and the patient was successfully treated with dapsone.

DISCUSSION

The diagnosis of anti-p200 pemphigoid was made in this case in spite of discrepancy between the IIF and immunoblotting results, and despite the fact that the target antigen in this disease is considered as being restricted to dermal sites. Anti-p200 pemphigoid usually begins in the second part of life and differs from standard bullous pemphigoid in terms of more frequent mucous membrane and cephalic involvement, as well as a greater degree of miliary scarring. This disease appears more prominent in males and is associated with psoriasis in around one third of cases. Autoantibodies recognize laminin gamma-1, an extra-desmosomal protein that contributes to dermal-epidermal adhesion.

CONCLUSION

This recently described disease as probably under-diagnosed in France. It should be considered in atypical presentations of bullous disease. Diagnosis is confirmed by immunoblotting detection of autoantibodies directed against a 200-kD antigen normally present in the extract. Dapsone appears to be the most effective treatment.

[Preventive crisis management in general outpatient palliative care - prospectively cross-sectional study of General Practitioners in Eastern Bavaria]

BACKGROUND

General out-patient palliative care (GOPC) must be integrated into the care of patients with life-limiting diseases. Aim of the study was to evaluate experiences of general practitioners concerning advance directives and palliative emergency sheets.

METHODS

A self-provided survey was mailed to all general practitioners in Regensburg (cross-sectional study). Main outcome measures included responses regarding a palliative emergency sheet (PES) and a palliative emergency plan (PEP). The investigation period was four months. The analysis was performed using defined criteria (e. g. professional experience concerning palliative care patients, patients treated in nursing homes, patients with dementia).

RESULTS

Sixty-nine questionnaires from 259 were analysed (response rate 27 %). 86 % of respondents named practical experience in the care of palliative patients, 46 % named theoretical knowledge in this field. 41 % and 40 % consider creating an advance directive for their practical work as important/very important (p = 0.004 concerning the treatment of more than five palliative care patients per three months). 52 % and 49 % regard a PES or a PEP to be relevant (PES median: 6.5, SD ± 2.7; PEP median: 6.5 SD ± 2.9; inter-group analysis p < 0.05). 94 % of respondents name the general practitioner to be suitable for creating an advance directive.

CONCLUSION

In Germany, GOPC in end-of-life care is very important. This study shows that advance directives were declared as an important instrument for patients? autonomy. The sense of PES and PEP to ensure patients? autonomy, especially for acute emergency medical palliative care, must be better recognized. However, the increase in acceptance in the GOPC for such instruments must be disclosed. Further studies to investigate this problem are necessary.

Are we giving patients enough information on how to use topical treatments? Analysis of 767 prescriptions in psoriasis

BACKGROUND

Unclear instructions probably contribute to the suboptimal efficacy and adherence to topical agents in psoriasis.

OBJECTIVES

To analyse the quality of prescriptions for topical therapy in psoriasis and to determine factors associated with high-quality prescription writing.

METHODS

We made a systematic analysis of 767 topical prescriptions written by dermatologists and general practitioners (GPs). The following parameters were recorded: writing mode (electronic vs. hand written), indication of formulation, frequency of administration, duration of treatment, indication of areas to be treated, and indication of amount of product to be used. We considered prescriptions of high quality to be those including at least four of the five prospectively defined quality parameters.

RESULTS

Only 35·7% of prescriptions fulfilled the definition of a high-quality prescription. Quality of prescription writing was significantly influenced by two factors: electronic writing [odds ratio (OR) 3·04, 95% confidence interval (CI) 2·2-4·21; P < 10(-4) ] and specialty of the prescriber, dermatologists writing higher quality prescriptions compared with GPs (OR 1·61, 95% CI 1·54-2·14; P < 10(-4) ).

CONCLUSIONS

Almost two-thirds of topical prescriptions are not adequately written and do not include the required information to help patients manage their topical treatment in psoriasis correctly. The quality of topical prescriptions could be improved by making the use of electronic prescriptions widespread and by the development of aids for easy evaluation of the right amount of topical treatment to be applied according to body surface area involved.

Improvement of Rat Islet Viability during Transplantation: Validation of Pharmacological Approach to Induce VEGF Overexpression

Delayed and insufficient revascularization during islet transplantation deprives islets of oxygen and nutrients, resulting in graft failure. Vascular endothelial growth factor (VEGF) could play a critical role in islet revascularization. We aimed to develop pharmacological strategies for VEGF overexpression in pancreatic islets using the iron chelator deferoxamine (DFO), thus avoiding obstacles or safety risks associated with gene therapy. Rat pancreatic islets were infected in vivo using an adenovirus (ADE) encoding human VEGF gene (4.108 pfu/pancreas) or were incubated in the presence of DFO (10 μmol/L). In vitro viability, functionality, and the secretion of VEGF were evaluated in islets 1 and 3 days after treatment. Infected islets or islets incubated with DFO were transplanted into the liver of syngenic diabetic rats and the graft efficiency was estimated in vivo by measuring body weight, glycemia, C-peptide secretion, and animal survival over a period of 2 months. DFO induced transient VEGF overexpression over 3 days, whereas infection with ADE resulted in prolonged VEGF overexpression lasting 14 days; however, this was toxic and decreased islet viability and functionality. The in vivo study showed a decrease in rat deaths after the transplantation of islets treated with DFO or ADE compared with the sham and control group. ADE treatment improved body weight and C-peptide levels. Gene therapy and DFO improved metabolic control in diabetic rats after transplantation, but this effect was limited in the presence of DFO. The pharmacological approach is an interesting strategy for improving graft efficiency during transplantation, but this approach needs to be improved with drugs that are more specific.

[Anesthesiology and palliative medicine. Structured results of a prospective questionnaire-based survey in German hospitals]

BACKGROUND

Anesthesiology departments were often integrated into the primary formation of palliative activities in Germany. The aim of this study was to present the current integration of anesthesiology departments into palliative care activities in Germany.

METHODS

The objective was to determine current activities of anesthesiology departments in in-hospital palliative care. A quantitative study was carried out based on a self-administered structured questionnaire used during telephone interviews.

RESULTS

A total of 168 out of 244 hospitals consented to participate in the study and the response rate was 69%. In-hospital palliative care activities were reported for most of the surveyed hospitals. Only two hospitals in the maximum level of care reported no activities. Participation in these activities by anesthesiology departments was described in up to 92%. Historically, most activities are due to the commitment of individuals, whereas the development of palliative care of cancer pain services and hospital support teams took place in the university hospitals by 2005.

CONCLUSIONS

Until 2005 many university palliative care activities had their origins in cancer pain services. These were often integrated into anesthesiology departments. Currently, anesthesiology departments work as an integrative part of palliative medicine. However, it appears from the present results that there is a domination of internal medicine (especially hematology and oncology) in palliative activities in German hospitals. This allows the focus of palliative activities to be formed by subjective specialist interests. Such a state seems to be reduced by the integration of anesthesiology departments because of their neutrality with respect to faculty-specific medical interests. Advantages or disadvantages of these circumstances are not considered by the present investigation.

Fluorodeoxyglucose positron emission tomography fails to detect distant metastases at initial staging of melanoma patients with metastatic involvement of sentinel lymph node

BACKGROUND

Positron emission tomography (PET) using fluorodeoxyglucose (FDG) has proven to be more sensitive and accurate than other imaging modalities for the detection of distant metastases in patients with melanoma. Sentinel lymph node (SLN) status is the most important prognostic factor in melanoma patients with no evidence of distant metastasis.

OBJECTIVES

To assess the rate of distant metastases in patients with a positive SLN biopsy (SLNB).

METHODS

Forty-six consecutive patients with a positive SLNB underwent PET or PET-computed tomography within 6 weeks of the SLNB procedure. The patients did not present any clinical sign of nodal involvement or of distant metastasis. PET findings were classified as positive, negative or nonconclusive.

RESULTS

No patient had a positive PET scan for distant metastasis. Six patients (13%) had a nonconclusive PET scan; none of them presented distant metastasis within 12 months. Forty patients (87%) had a negative PET scan; among them five (12%) presented with distant metastasis within 12 months.

CONCLUSIONS

Fluorodeoxyglucose positron emission tomography failed to detect distant metastases at initial staging in patients with a positive SLNB, even in patients who presented with distant metastases within 12 months after the FDG PET scan. These results could be explained by the low prevalence of macroscopic metastatic disease at this stage and by the important delay between the onset of the spread of microscopic metastatic disease and the identification by PET scan of macroscopic metastatic disease.

[Breast-feeding training programme as intervention approach at the hospital level: results of evaluation of the first phase of the STELLA study]

BACKGROUND

The health-promoting short- and long-term effects of breast-feeding are supported by a vast scientific literature. The Bavarian prospective cohort study 2005/2006 showed regional variations of breast-feeding rates. Furthermore, improvement in counselling mothers, particularly with regard to prevention and handling of breast-feeding problems, has a great potential for health promotion. The objective of this study is to promote breast-feeding in maternity clinics by improving the surrounding conditions.

STUDY DESIGN

A clinic-based and community-related intervention trial was carried out in Lower Bavaria as a model region with below average breast-feeding rates. (1) INTERVENTION: an advanced training of maternity ward professionals of 10 hospitals and after-care midwives was performed from May until December 2008. The training programme was based on the WHO/UNICEF criteria of the "Ten Steps to Successful Breastfeeding" to deepen the breast-feeding knowledge and to improve the breast-feeding management. (2) EVALUATION: A singular assessment of the advanced training programme was undertaken concerning an increase of knowledge and the practicability in clinical everyday life by participants; improvements of the maternity wards were assessed via structural interviews with maternity ward staff before and after intervention.

RESULTS

Approximately 85% (n=378) of the staff of the 10 maternity clinics attended the training course. The survey after the training programme (response rate 83%) indicated that more than 80% of the participants stated to have learned something new and to be able to use the knowledge acquired for their own practice. Results of the clinic interviews showed a transfer of training contents into clinical work routines. Improvements at interview date were shown best for bonding (all 10 maternity clinics), for additional feeding (8 maternity clinics) as well as for 24-h rooming-in and mother counselling (7 maternal clinics each).

CONCLUSION

Training of maternity ward professionals accounts for baby-friendly conditions in maternity clinics. Most willingness for improvements was shown by maternity ward staff particularly for bonding between mother and child as well as for additional feeding. Considerable differences between the hospitals were observed for the promotion of infant formulas before and after the intervention.

Joint clinical and pathological review meetings improve patient care: a prospective evaluation in dermatology

BACKGROUND

Joint clinical and pathological review meeting exists in most academic dermatology departments.

OBJECTIVE

The primary objective of the study was to assess the impact of the joint clinical and pathological review meeting in dermatology on patient care.

METHODS

Prospective descriptive study over 6 months (May to October 2008) on all clinical cases of dermatology reviewed at the joint clinical and pathological review meeting in our University Hospital.

RESULTS

A total of 139 cases were reviewed during the 6-month period. In 97 cases (69.8%), the joint clinical and pathological review meeting had a positive impact on final diagnosis and/or on patient management. For 27 cases, a consensus diagnosis different from the initial proposal was established. In 21 cases, the joint clinical and pathological review meeting led to additional investigations or therapeutic proposals. The impact of the joint clinical and pathological review meeting was highest for inflammatory skin diseases.

CONCLUSIONS

The joint clinical and pathological review meeting is a useful procedure to improve diagnostic accuracy in difficult cases.

[Psychosocial aspects and body pain: results from an employee survey in the frame of the MAF-project "integrated health management in companies: employee survey about working conditions as management tool"]

INTRODUCTION

The aim of the study is to present a compact employee attitude survey for companies within a health care management tool. Beside body pains work-related psychosocial risk factors as well as further influencing factors, are taken into consideration. The questionnaire was evaluated by 6 Bavarian companies.

METHOD

Potential influencing factors on physical problems like back pain, neck- and shoulder tension, gastro-intestinal diseases and headache were examined by multiple analysis. Dissatisfaction with working conditions was also examined in the same way. All analyses were carried out age and sex adjusted.

RESULTS

Statistical analyses are based on 3,720 employees of 3 companies out of a total of 6 companies who answered the questionnaires. Response rates of the different companies ranged from 34 to 60%. Psychomental demands and psychosocial strains were found to be the strongest predictors for body pains as well as for dissatisfaction with working conditions.

CONCLUSIONS

The introduced questionnaire is easy to implement within the framework of a company health care management. It has an holistic approach. We could demonstrate that this instrument is able to reveal multiple aspects of work-related body pain as well as multiple aspects of dissatisfaction with working conditions. Thus it is a starting point for the development of necessary measures for health promotion.

Polycystin-2 activity is controlled by transcriptional coactivator with PDZ binding motif and PALS1-associated tight junction protein

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent monogenic cause of kidney failure, characterized by the development of renal cysts. ADPKD is caused by mutations of the polycystin-1 (PC1) or polycystin-2 (PC2) genes. PC2 encodes a Ca(2+)-permeable cation channel, and its dysfunction has been implicated in cyst development. The transcriptional coactivator with PDZ binding motif (TAZ) is required for the integrity of renal cilia. Its absence results in the development of renal cysts in a knock-out mouse model. TAZ directly interacts with PC2, and it has been suggested that another yet unidentified PDZ domain protein may be involved in the TAZ/PC2 interaction. Here we describe a novel interaction of TAZ with the multi-PDZ-containing PALS1-associated tight junction protein (PATJ). TAZ interacts with both the N-terminal PDZ domains 1-3 and the C-terminal PDZ domains 8-10 of PATJ, suggesting two distinct TAZ binding domains. We also show that the C terminus of PC2 strongly interacts with PDZ domains 8-10 and to a weaker extent with PDZ domains 1-3 of PATJ. Finally, we demonstrate that both TAZ and PATJ impair PC2 channel activity when co-expressed with PC2 in oocytes of Xenopus laevis. These results implicate TAZ and PATJ as novel regulatory elements of the PC2 channel and might thus be involved in ADPKD pathology.

Psoriasis: an epidemiological evaluation of disease burden in 590 patients

BACKGROUND

There are limited data available on the economical burden of psoriasis and its impact on everyday life.

OBJECTIVE

The aim of this study was to evaluate the impact of psoriasis on personal and professional life, and to evaluate the cost of psoriasis for the patient.

METHODS

We performed a cross-sectional study in psoriasis patients. All patients aged >or=18 years with a diagnosis of plaque-psoriasis confirmed by a physician were included. A self-administered questionnaire evaluating everyday life was constructed with members of the French association of psoriasis patients. In addition, the Dermatology Life Quality Index (DLQI), Working Productivity and Activity Impairment and individual costs were assessed.

RESULTS

A total of 590 patients completed the study. Mean age of the responders was 56 years. The mean DLQI score was 8.5 for patients with severe psoriasis vs. 6.4 for mild psoriasis. Global loss of productivity was 10.7% without significant difference according to the disease severity. Daily activities alteration was most important in patients with severe psoriasis. In this study, 36.8% of patients with severe psoriasis reported a negative impact on their professional life vs. 19.6% for patients with mild psoriasis (P = 0.002). Time devoted to phototherapy was on average 33 h/year/patient and the application of emollients took 25 h/year/patient; 47.3% of patients had a feeling to clean the house more often, in correlation with the severity of the disease. Mean out-of-pocket expenses for the disease was estimated to be 543 euro/year/patient. High impact of psoriasis on quality of life (DLQI >10), age <40 years and joint involvement were significantly associated with an increased risk of loss of work productivity.

CONCLUSION

Psoriasis, particularly severe psoriasis, is a true burden for patients and impacts significantly everyday life and patient's economical resources.

[Can medical treatment be the first-line treatment for most ectopic pregnancies? A series of 202 patients]

OBJECTIVES

To assess the efficacy and safety of a liberal policy of medical treatment for ectopic pregnancies (EUP).

MATERIAL AND METHODS

Retrospective study of EUP that received active management between January 1999 and December 2003. Patients with rupture or near-rupture and those who refused medical treatment received surgical treatment. Other patients were treated by methotrexate.

RESULTS

Two hundred and two EUP were managed; 26 % were treated surgically, 74 % medically. The success rate of medical treatment was 83 %. A ss-hCG threshold of 2526 IU/l was selected. Under this level, the success rate was 90.7 % compared with 68 % when it was higher (p=0.001). Cardiac activity tripled the failure rate. Morbidity with medical treatment consisted of an augmentation in transaminases in 18.8 % and one case of severe dermatosis (0.7 %). Almost half of the patients treated medically required hospitalizations.

CONCLUSION

The extension of medical treatment in our population to 74 % of all EUP yielded a high success rate, 83 %.

The effect of pinholes of different sizes on visual acuity under different refracting states and ambient lighting conditions*

Purpose: The purpose of this pilot study was to investigate the effect of different size pinholes on visual acuity (VA) at near (0.4 m) while various factors were altered. The alterations made involved accommodation and illumination.Method: Four subjects were selected and their ages ranged from 7 to 14 years. Subjective refractions were performed and then near visual acuities were measured at 0.4 m under two different lighting conditions (460 lux and 1 lux) by adding stigmatic (or spherical) lenses of positive and negative powers in front of pinholes of diameters 1.5 mm and 2 mm.Results: The results showed that there was an improvement in VA in most, however, the size of the pinhole played a minor role. Low illumination did have a drastic effect on our results not only by decreasing the amount of lenses used for near that gave more positive results, but also when the pinhole was placed in front of the subjects. According to Borish, the pinhole does improve VA by a straight forward process of elimination produced by spherical aberrations of the eye. However, this did not seem to be the case in this study under conditions of low illumination.Conclusion: The pinhole effect offers improvement in VA at near by reducing the amount of blupresented to the retina. This study showed that alsubjects had an improvement in VA of at least twolines in high illumination. Pinhole size did not alte the results sufficiently thus suggesting that a pinhole, no matter the size, should increase the VA. However this was not the case when illumination was decreased.

Geoepidemiologic considerations of auto-immune pemphigus

Sporadic and endemic forms of pemphigus foliaceus exist. Incidences of the various forms of pemphigus vary from country to country: pemphigus vulgaris is most common in Europe and the USA, whereas pemphigus foliaceus is more prevalent in Northern Africa, Turkey and Southern America. Endemic pemphigus foliaceus (also known as fogo selvagem and Brazilian pemphigus foliaceus) is a variant of the disease that is frequently diagnosed in some areas of Brazil and other underdeveloped areas of the world, including Tunisia and Colombia. Both genetic and environmental factors have been associated with the occurrence of auto-immune pemphigus and endemic pemphigus is very interesting from this point of view. Most of the patients with auto-immune pemphigus are aged 40-60 years at the onset of the disease. The incidence and prevalence of pemphigus are low. The demonstration of association of pemphigus vulgaris with HLA class II alleles is supported by various studies.

CONSORT adoption and quality of reporting of randomized controlled trials: a systematic analysis in two dermatology journals

BACKGROUND

CONSORT (Consolidated Standards for Reporting Trials) guidelines were constructed to ensure optimal reporting quality of randomized controlled trials (RCTs).

OBJECTIVES

To determine the effect of the adoption of CONSORT on the reporting quality of RCTs, we performed a systematic evaluation of RCTs published in two dermatology journals pre- and post-CONSORT adoption.

METHODS

The journals selected for the study were the Journal of the American Academy of Dermatology and the British Journal of Dermatology. We selected RCTs published in 1997 and 2006 using both Medline and hand searching. The following critical CONSORT criteria were recorded: sample size, type of disease studied, type of control, single-centre or multicentre study, type of funding, blinding, methods and type of randomization, definition of a primary endpoint, justification for sample size selection and power calculation, population for analysis, and adequacy of group comparison. A multivariable analysis was conducted to determine factors associated with optimal reporting quality.

RESULTS

In total, 98 studies were included. Improvement in reporting quality was evident for the specification of the randomization method (20% in 1997 vs. 45% in 2006, P < 0.01) and for the justification of sample size (22% in 1997 vs. 43% in 2006, P = 0.027). The percentage of studies with optimal reporting quality increased from 11% in 1997 to 28% in 2006 (P = 0.03). Factors significantly associated with a good methodological quality were pharmaceutical industry funding and publication in 2006 vs. 1997.

CONCLUSIONS

There is a need to improve the reporting quality of RCTs published in dermatology journals.

Particle and gaseous emissions from compressed natural gas and ultralow sulphur diesel-fuelled buses at four steady engine loads

Exhaust emissions from thirteen compressed natural gas (CNG) and nine ultralow sulphur diesel in-service transport buses were monitored on a chassis dynamometer. Measurements were carried out at idle and at three steady engine loads of 25%, 50% and 100% of maximum power at a fixed speed of 60 km h(-1). Emission factors were estimated for particle mass and number, carbon dioxide and oxides of nitrogen for two types of CNG buses (Scania and MAN, compatible with Euro 2 and 3 emission standards, respectively) and two types of diesel buses (Volvo Pre-Euro/Euro1 and Mercedez OC500 Euro3). All emission factors increased with load. The median particle mass emission factor for the CNG buses was less than 1% of that from the diesel buses at all loads. However, the particle number emission factors did not show a statistically significant difference between buses operating on the two types of fuel. In this paper, for the very first time, particle number emission factors are presented at four steady state engine loads for CNG buses. Median values ranged from the order of 10(12) particles min(-)(1) at idle to 10(15) particles km(-)(1) at full power. Most of the particles observed in the CNG emissions were in the nanoparticle size range and likely to be composed of volatile organic compounds The CO2 emission factors were about 20% to 30% greater for the diesel buses over the CNG buses, while the oxides of nitrogen emission factors did not show any difference due to the large variation between buses.

Phase II trial of pegylated liposomal doxorubicin-cyclophosphamide combination as first-line chemotherapy in older metastatic breast cancer patients

OBJECTIVE

To evaluate the efficacy and toxicity of pegylated liposomal doxorubicin (PLD; Caelyx)-cyclophosphamide combination in older metastatic breast cancer patients.

METHODS

A multicenter phase II trial was conducted. Inclusion criteria were age 65-75 years, ECOG 0-1 and left ventricular ejection fraction > or =50%. First-line chemotherapy was given to metastatic breast cancer patients resistant to hormonal therapy. The treatment schedule was PLD 40 mg/m(2) and cyclophosphamide 500 mg/m(2) on day 1 every 4 weeks. Efficacy was the primary endpoint, while response duration and tolerance were the secondary endpoints.

RESULTS

Thirty-five patients (median age 71.3 years) were enrolled. No treatment-related death, no congestive heart failure or decrease in left ventricular ejection fraction and no febrile neutropenia were reported.

TOXICITY

grade 3 dyspnea was found in 1 patient, neutropenia in 11 patients (7 grade 3, 4 grade 4), grade 3 mucositis in 4 patients, grade 3 hand-foot syndrome in 1 patient and a generalized rash in 1 patient. An objective response (complete and partial response) was achieved in 10 (28.6%) patients and disease control in 24 (69%) with a progression-free survival of 8.8 months and a median overall survival of 20.3 months.

CONCLUSION

The PLD-cyclophosphamide combination is moderately active and safe in elderly metastatic breast cancer patients, but cannot be recommended routinely due to myelotoxicity and mucositis hazards.

Sagittal alignment correction of the thoracolumbar junction in idiopathic scoliosis by in situ bending technique

A long thoracolumbar sagittal rectitude is sometimes present in adolescent idiopathic scoliosis. The purpose of this study was to identify typical patterns, by comparing frontal plane deformities and vertebral rotation leading to this rectitude. Surgical thoracolumbar alignment correction by three-dimensional in situ bending of rods was then analyzed. Pre- and postoperative radiographs of 24 patients with scoliosis (36-104 degrees) were reviewed using Spineview software. Frontal curves and levels of sagittal rectitude were determined. Thoracic kyphosis, lumbar lordosis, sacral slope, pelvic incidence, pelvic tilt, T9 and T1 tilt were measured. Vertebral rotation was measured by computed tomography, Perdriolle's, Nash and Moe's methods. The intervertebral mobility of the rectitude was analyzed on side bending radiographs. Three patterns leading to sagittal rectitude were identified: 11 main thoracic curves (Lenke 1, King 3) with cranial prolongation of the physiological thoracolumbar junction (T7T12) and maximal vertebral rotation above this zone, 13 double major or thoracolumbar curves (Lenke 3 or 5, King 1 or 2) with cranial and caudal prolongation (T9L3) and maximal rotation above and below, 1 lumbar curve (Lenke 5) with caudal rectitude (T12L4) and maximal rotation at L1. There was no relationship between intervertebral mobility and rectitude. Postoperatively, this zone of rectitude disappeared in 17 out of 24 patients after anterior release followed by posterior instrumentation using the in situ bending technique. In situ bending realizes a stepwise correction of the three-dimensional deformity at different levels. An accurate preoperative analysis is mandatory to achieve an adequate sagittal balance, frontal curve correction and vertebral derotation simultaneously. The determined patterns of thoracolumbar rectitude are helpful to plan surgical correction accurately.

Awareness, knowledge and attitudes towards sun protection among skin cancer-treated patients in France

BACKGROUND

The incidence of skin cancer has risen over the past years, owing to increased exposure to ultraviolet radiation. Sun protection measures include avoiding exposure to the sun, using covering clothing and applying sunscreen. We evaluated the knowledge and compliance with advices about sun protection in a population of patients who had presented skin tumour(s).

SUBJECTS AND METHODS

A 30 question self-reporting questionnaire evaluating sun protective behaviour was distributed to 217 consecutive skin cancer-treated patients and completed by 198 of them.

RESULTS

72% of the responders had presented a melanoma, and 26% of them had presented only non-melanoma skin cancer. The present survey shows that patients who have had a skin cancer were aware of the cancer related risk of sunlight since 98% of the responders knew that ultraviolet radiations can include skin cancer. These patients did also take sun-protective measures because 73% of them had worn covering clothes when in the sun and 59% of them avoided outdoor activities during the midday hours.

CONCLUSION

These results suggest that, after diagnosis of a skin cancer, patients limited their sun exposure; and wear protective clothing. However, sun-protection measures did not seem to be completely adequate. An evaluation of the various barriers to sun safety might be a key to understanding the sub-optimal sun protection.
