RESUMEN

As a consequence of demographic developments, legal questions regarding medical treatment of the elderly are receiving increasing attention. In the first instance, elderly patients are of course just normal patients. However, they often require a special degree of medical care from physicians and nurses. From a legal perspective, this leads to a heightened level of due diligence from medical practitioners. Specific legal challenges come into play when dealing with patients who are unable to give consent, or who are subject to personal custody. Additionally, patient's provisions and health care proxies are playing an ever more important role. Thus, an overview of the different legal aspects has become absolutely necessary for medical practitioners.

RESUMEN

Obese breast cancer patients have a higher risk of lymph node metastasis and a poorer prognosis compared to patients with normal weight. For obese women with node-positive breast cancer, an association between body weight and prognosis remains unclear. In this retrospective study, we analyzed patient data from the Phase-III ADEBAR trial, in which high-risk breast cancer patients (pT1-4, pN2-3, pM0) were randomized into a docetaxel-based versus epirubicin-based chemotherapy regimen. Patients were grouped according to their BMI value as underweight/normal weight (BMI < 25 kg/m(2); n = 543), overweight (BMI 25-29.9 kg/m(2); n = 482) or obese (BMI ≥ 30 kg/m(2); n = 285). Overweight and obese patients were older, had larger tumors and were more likely to be postmenopausal at the time of diagnosis compared to underweight/normal-weight patients (all p < 0.001). Multivariate Cox regression analyses adjusting for age and histopathological tumor features showed that obese patients had a significantly shorter disease-free survival (DFS; HR 1.43; 95 % CI 1.11-1.86; p = 0.006) and overall survival (OS; HR 1.56; 95 % CI 1.14-2.14; p = 0.006) than non-obese patients. Subgroup analyses revealed that the differences in DFS and OS were significant for postmenopausal but not for premenopausal patients, and that the survival benefit of non-obese patients was more pronounced in women with hormone-receptor-positive disease. Obesity constitutes an independent, adverse prognostic factor in high-risk node-positive breast cancer patients, in particular for postmenopausal women and women with hormone-receptor-positive disease.

RESUMEN

The oestrogenised vagina is colonised by Candida species in at least 20% of women; in late pregnancy and in immunosuppressed patients, this increases to at least 30%. In most cases, Candida albicans is involved. Host factors, particularly local defence mechanisms, gene polymorphisms, allergies, serum glucose levels, antibiotics, psycho-social stress and oestrogens influence the risk of candidal vulvovaginitis. Non-albicans species, particularly Candida glabrata, and in rare cases also Saccharomyces cerevisiae, cause less than 10% of all cases of vulvovaginitis with some regional variation; these are generally associated with milder signs and symptoms than normally seen with a C. albicans-associated vaginitis. Typical symptoms include premenstrual itching, burning, redness and odourless discharge. Although itching and redness of the introitus and vagina are typical symptoms, only 35-40% of women reporting genital itching in fact suffer from vulvovaginal candidosis. Medical history, clinical examination and microscopic examination of vaginal content using 400× optical magnification, or preferably phase contrast microscopy, are essential for diagnosis. In clinically and microscopically unclear cases and in chronically recurring cases, a fungal culture for pathogen determination should be performed. In the event of non-C. albicans species, the minimum inhibitory concentration (MIC) should also be determined. Chronic mucocutaneous candidosis, a rarer disorder which can occur in both sexes, has other causes and requires different diagnostic and treatment measures. Treatment with all antimycotic agents on the market (polyenes such as nystatin; imidazoles such as clotrimazole; and many others including ciclopirox olamine) is easy to administer in acute cases and is successful in more than 80% of cases. All vaginal preparations of polyenes, imidazoles and ciclopirox olamine and oral triazoles (fluconazole, itraconazole) are equally effective (Table ); however, oral triazoles should not be administered during pregnancy according to the manufacturers. C. glabrata is not sufficiently sensitive to the usual dosages of antimycotic agents approved for gynaecological use. In other countries, vaginal suppositories of boric acid (600 mg, 1-2 times daily for 14 days) or flucytosine are recommended. Boric acid treatment is not allowed in Germany and flucytosine is not available. Eight hundred-milligram oral fluconazole per day for 2-3 weeks is therefore recommended in Germany. Due to the clinical persistence of C. glabrata despite treatment with high-dose fluconazole, oral posaconazole and, more recently, echinocandins such as micafungin are under discussion; echinocandins are very expensive, are not approved for this indication and are not supported by clinical evidence of their efficacy. In cases of vulvovaginal candidosis, resistance to C. albicans does not play a significant role in the use of polyenes or azoles. Candida krusei is resistant to the triazoles, fluconazole and itraconazole. For this reason, local imidazole, ciclopirox olamine or nystatin should be used. There are no studies to support this recommendation, however. Side effects, toxicity, embryotoxicity and allergies are not clinically significant. Vaginal treatment with clotrimazole in the first trimester of a pregnancy reduces the rate of premature births. Although it is not necessary to treat a vaginal colonisation of Candida in healthy women, vaginal administration of antimycotics is often recommended in the third trimester of pregnancy in Germany to reduce the rate of oral thrush and napkin dermatitis in healthy full-term newborns. Chronic recurrent vulvovaginal candidosis continues to be treated in intervals using suppressive therapy as long as immunological treatments are not available. The relapse rate associated with weekly or monthly oral fluconazole treatment over 6 months is approximately 50% after the conclusion of suppressive therapy according to current studies. Good results have been achieved with a fluconazole regimen using an initial 200 mg fluconazole per day on 3 days in the first week and a dosage-reduced maintenance therapy with 200 mg once a month for 1 year when the patient is free of symptoms and fungal infection (Table ). Future studies should include Candida autovaccination, antibodies to Candida virulence factors and other immunological experiments. Probiotics with appropriate lactobacillus strains should also be examined in future studies on the basis of encouraging initial results. Because of the high rate of false indications, OTC treatment (self-treatment by the patient) should be discouraged.

RESUMEN

PURPOSE: A new CE-marked portable desktop ion mobility spectrometer (VGTest) was used for detection of malodorous biogenic amines indicative of bacterial vaginosis (BV). This study aimed to assess the performance of this testing method for the first time in a routine ambulatory care clinic and to determine the relative levels of biogenic amines in vaginal fluid of BV. METHODS: Vaginal and cervical swabs (n = 57) were surveyed for infections. Cases of BV (n = 18) confirmed positive according to "Amsel" criteria and normal controls (n = 39) showing no infection under clinical examination and testing negative in wet mount microscopy were included in the IMS analysis. RESULTS: The trimethylamine (TMA) content in vaginal fluid of the BV-positive cases, AUCTMA/AUCTotal [mean 0.215 (range 0.15-0.35)] was significantly higher than normal controls [mean 0.06 (range 0.048-0.07)] p < 0.0001. The putrescine (1,4-diaminobutane, PUT) and cadaverine (1,5-diaminopentane, CAD) of BV-positive cases were above controls at borderline significance. The AUCTMA/AUCTotal ratios correlated neither with AUCPUT/AUCTotal nor AUCCAD/AUCTotal among BV-positive patients. In contrast, among normal controls all the biogenic amines were at a low level and the linear regression analysis revealed striking positive correlations of AUCTMA/AUCTotal with AUCPUT/AUCTotal (p < 0.05) and AUCCAD/AUCTotal (p < 0.001). The test shows 83 % sensitivity and 92 % specificity at a cut-off of AUCTMA/AUCTotal = 0.112 and AUC of receiver operator characteristic = 0.915 (0.81-0.97, 95 % CI). CONCLUSIONS: VGTest-IMS is accurate and feasible for point-of-care testing of BV in the ambulatory care setting. Further evaluations are in progress to assess the utility of VGTest-IMS for differential diagnosis of candidosis, non-BV infection and common inflammatory conditions.

RESUMEN

Spin-crossover (SCO) compounds are promising materials for a wide variety of industrial applications. However, the fundamental understanding of their nature of transition and its effect on the physical properties are still being fervently explored; the microscopic knowledge of their transition is essential for tailoring their properties. Here an attempt is made to correlate the changes in macroscopic physical properties with microscopic structural changes in the orthorhombic and monoclinic polymorphs of the SCO compound Fe(PM-Bia)2(NCS)2 (PM = N-2'-pyridylmethylene and Bia = 4-aminobiphenyl) by employing single-crystal X-ray diffraction, magnetization and DSC measurements. The dependence of macroscopic properties on cooperativity, highlighting the role of hydrogen bonding, π-π and van der Waals interactions is discussed. Values of entropy, enthalpy and cooperativity are calculated numerically based on the Slichter-Drickamer model. The particle size dependence of the magnetic properties is probed along with the thermal exchange and the kinetic behavior of the two polymorphs based on the dependence of magnetization on temperature scan rate and a theoretical model is proposed for the calculation of the non-equilibrium spin-phase fraction. Also a scan-rate-dependent two-step behavior observed for the orthorhombic polymorph, which is absent for the monoclinic polymorph, is reported. Moreover, it is found that the radiation dose from synchrotron radiation affects the spin-crossover process and shifts the transition region to lower temperatures, implying that the spin crossover can be tuned with radiation damage.

RESUMEN

BACKGROUND: Simultaneous adjuvant platinum-based radiochemotherapy in high-risk cervical cancer (CC) is an established treatment strategy. Sequential paclitaxel (Taxol) and platinum followed by radiotherapy may offer further advantages regarding toxicity. PATIENTS AND METHODS: An open-labeled randomized phase III trial was conducted to compare paclitaxel (175 mg/m(2)) plus carboplatin (AUC5) followed by radiation (50.4 Gy) (experimental arm-A) versus simultaneous radiochemotherapy with cisplatin (40 mg/m(2)/week) (arm-B) in patients with stage IB-IIB CC after surgery. Primary objective was progression-free survival (PFS). RESULTS: Overall, 271 patients were randomized and 263 were eligible for evaluation; 132 in arm-A and 131 in arm-B appropriately balanced. The estimated 2-year PFS was 81.8% [95% confidence interval (CI) 74.4-89.1] in arm-B versus 87.2% (95% CI 81.2-93.3) in arm-A (P = 0.235) and the corresponding 5-year survival rates were 85.8% in arm-A and 78.9% in arm-B (P = 0.25). Hematological grade 3/4 toxicity was higher in arm-B. Alopecia (87.9% versus 4.1%; P < 0.001) and neurotoxicity (65.9% versus 15.6%; P < 0.001) were significantly higher in arm-A. Early treatment termination was significantly more frequent in arm-B than in arm-A (32.1% versus 12.9%; P = 0.001). CONCLUSIONS: Sequential chemotherapy and radiation in high-risk CC could not show any significant survival benefit; however, a different toxicity profile appeared. This sequential regime may constitute an alternative option when contraindications for immediate postoperative radiation are present.

RESUMEN

Corticotropin-releasing hormone (CRH) and its receptors are expressed in human placenta. Recently, the impaired function of this system has been associated with a number of complications of pregnancy, including pre-eclampsia. The aim of the study was to test the hypothesis that CRH participates in the pathophysiology of pre-eclampsia through the induction of macrophage-mediated apoptosis of extravillous trophoblasts (EVTs). We found that the expression of CRH was increased in the EVT of the placental bed biopsy specimens from pre-eclamptic pregnancies (1.8-fold increase; P < 0.05). In addition, significantly larger numbers of apoptotic EVT were detected in pre-eclamptic placentas compared with normal ones (P < 0.05), and only in pre-eclamptic placentas, decidual macrophages were found to be Fas ligand (FasL)-positive. In vitro studies on the effect of CRH on human macrophages suggested that CRH induced the expression of the FasL protein in human macrophages and potentiated their ability to induce the apoptosis of a Fas-expressing EVT-based hybridoma cell line in co-cultures. These findings demonstrate a possible mechanism by which the aberrant expression of CRH in pre-eclampsia may activate the FasL-positive decidual macrophages, impair the physiological turnover of EVT and eventually disturb placentation.

RESUMEN

BACKGROUND AND OBJECTIVES: The aim of this study was to determine the diagnostic efficacy of backscattering intensity measurements in optical coherence tomography in identifying different grades of cervical intraepithelial dysplasia. STUDY DESIGN/MATERIALS AND METHODS: OCT images were taken from 153 unsuspicious and suspicious areas of 30 fresh conisation and hysterectomy specimens, evaluated by two blinded investigators using a six-grade classification (normal, inflammation, CIN1, CIN2, CIN3, squamous carcinoma) and later compared to the corresponding histology. Differences between judgments based on either the histology or the OCT images were investigated employing Correspondence Analysis (CA). Further, we explored the extent as to which backscattering intensity profiles of OCT images contained the essential information required for a reliable and valid diagnosis, using Linear Discriminant Analysis (LDA). RESULTS: The CA of histology- and OCT-based judgments suggests that the diagnostic process may be characterized in terms of two stochastically independent underlying ("latent") variables, the first of them reflecting the definiteness with which CIN classes are identified, the second reflecting a bias towards diagnosing inflammation on the side of the OCT-based judgments. This finding is supported by the results of LDAs, where histology and OCT categorizations differ in particular with respect to the positions of inflammation and CIN1. Possibly, a second canonical variable has to be assumed accounting for the evaluation of carcinoma. CONCLUSIONS: The systematic differences between histology-based and OCT-based diagnoses suggest that the use of available information is influenced by perceptual and/or cognitive biases. Apart from this it seems that the profiles appear to provide a remarkably large amount of information determining the main course of the diagnostic process.

RESUMEN

UNLABELLED: AIM AND SETTING: To test the effects of crude extracts from flax (Linum usitatissimum) on progesterone and estradiol and ERα and ß/PR production in choriocarcinoma cell lines Jeg 3 and BeWo. Tumor trophoblast cells (Jeg 3 and BeWo) were incubated in the presence of different concentrations of the flax crude extracts. Estradiol and progesterone production was measured. Estrogen receptor α and ß as well as progesterone receptor expressions were also assessed. RESULTS: In Jeg 3 cells, progesterone production was downregulated by flax root and leaves extract, while in BeWo cells only flax root extract did manage to downregulate progesterone production. ERß expression was significantly downregulated by flax root and flax leaves extract in both cell lines; on the contrary, ERα expression was increased by flax leaves extract in BeWo cells. PR expression was downregulated by flax leaves extract in Jeg 3 and by flax root extract in BeWo cells. CONCLUSION: Flax extracts derived from leaves and especially from roots can modify progesterone and possibly estradiol production, while at the same time they seem to alter ERß expression. Further studies on animal models and adequately designed retrospective epidemiological studies are imperative to clarify this role upon progesterone.

RESUMEN

OBJECTIVES: To compare two different systems for optical coherence tomography for the diagnosis of cervical dysplasia and to assess potential benefits of three-dimensional imaging. MATERIALS AND METHODS: OCT images were taken from unsuspicious and suspicious areas of fresh conisation specimens using two different imaging systems, one with the capability to produce three-dimensional images. All OCT images were separately evaluated by two blinded investigators based on a 6-grade classification (normal, inflammation, CIN 1, CIN 2, CIN 3, squamous carcinoma) and later compared to the corresponding histology. Sensitivity and specificity of OCT in detecting cervical dysplasia were determined. RESULTS: OCT images using both OCT systems were taken from 46 sites in ten conisation specimens and later compared to the corresponding histology. CIN lesions were diagnosed correctly by the two-dimensional OCT system with a sensitivity and specificity of 91% and 78% accordingly. Using the three-dimensional system sensitivity and specificity were 82% and 86% accordingly. CONCLUSIONS: Both OCT systems used were highly sensitive in identifying cervical intraepithelial neoplasia. Despite technical problems experienced in the present series, we believe that three-dimensional imaging has the potential to further improve the accuracy of optical coherence tomography.

RESUMEN

The crystal structure of ammonium rubidium nonaoxotetratellurate(IV) dihydrate has been studied as a function of pressure up to 7.40 GPa. The ambient-pressure structure is characterized by the co-existence of three different Te-O polyhedra (TeO(3), TeO(4) and TeO(5)), which are connected to form layers. NH(4)(+), H(2)O and Rb(+) are incorporated between the layers. Both the Rb1 position, which is located on a twofold axis, and the Rb2 position are partially occupied. The three different types of coordination polyhedra around Te(4+) are stable up to at least 5.05 GPa. No phase transition is observed. The fit of the unit-cell volume as a function of pressure gives a zero-pressure bulk modulus of 34 (1) GPa with a zero-pressure volume of V(0) = 2620 (4) Å(3) [B' = 1.4 (2)].

RESUMEN

BACKGROUND: Prenatal 3-dimensional (3D) ultrasound allows volumetry of the fetal brain, liver and measurement of myocardial mass (MM). We studied the reliability of this method in an interdisciplinary approach, defined the relation of the values throughout gestation, and evaluated the results in fetuses with congenital heart disease (CHD). METHODS: In 104 fetuses (39 with CHD) between 14 and 38 weeks of gestation 3D ultrasound was prospectively performed. Data sets of brain, abdomen and heart were stored for off-line analysis of volumes and MM. Descriptive statistics, coefficients of correlation and of variation (CV) were performed. RESULTS: Volumetric data set acquirement was feasible in all pregnancies, lasted approximately 10 min, but off-line analysis was feasible in only 66% lasting about 45 min. MM increased in a linear fashion during gestation. CV were 11.0 and 10.8 for the left, 14.39 and 12.66, respectively, for the right MM. Median ratio between right and left MM was 0.88 in normal fetuses, and 8.25 in fetuses with hypoplastic left heart syndrome. Intra- and interobserver variabilities revealed CVs of 2.46 and 11.80, respectively, for brain volumetry, and CVs of 3.16 and 29.2, respectively, for liver volumetry. Both brain and liver volumes were positively associated with gestational age, and did not show different growth patterns in fetuses with CHD. CONCLUSIONS: Prenatal volumetry is time-consuming, but reliable especially for left MM and brain volume. Linear growth of brain and liver volume is present in utero irrespective of CHD. Application of our reference graphs of MM growth allows early differentiation in CHD.

RESUMEN

BACKGROUND: This randomised phase III trial was carried out to compare the efficacy and safety of epirubicin and cyclophosphamide (EC) with epirubicin and docetaxel (Taxotere) (ED) as first-line chemotherapy for metastatic breast cancer. PATIENTS AND METHODS: Patients (n = 240) were randomly assigned to receive either ED (epirubicin 75 mg/m(2) and docetaxel 75 mg/m(2)) or EC (epirubicin 90 mg/m(2) and cyclophosphamide 600 mg/m(2)). The primary end point was objective response rate (ORR). Secondary end points were progression-free survival (PFS), overall survival (OS), and safety. RESULTS: ORR for patients randomly assigned to receive EC and ED were 42% and 47%, respectively (P = 0.63). Median PFS [10.1 versus 10.3 months; hazard ratio (HR) 0.98; log-rank P = 0.38] and OS (19.9 versus 30.0 months; HR 0.663; log-rank P = 0.21) were comparable in both arms. Although grade 3/4 leucopenia occurred more frequently with ED (81% versus 73%; P = 0.01), there were no significant differences in the incidence of febrile neutropenia and grade 3/4 infections. Grade 3/4 non-haematologic toxicity was infrequent in both arms. Congestive heart failure was observed in one patient in each arm. CONCLUSION: In this randomised trial, no differences in the efficacy study end points were observed between the two treatment arms.

RESUMEN

OBJECTIVE: Optical coherence tomography (OCT) is a non-invasive high-resolution imaging technique that permits characterization of microarchitectural features of tissue up to 2 mm in depth in real time. The purpose of this study was to evaluate the feasibility of OCT for the identification of precancerous (cervical intraepithelial neoplasia (CIN)) and cancerous lesions of the uterine cervix. METHODS: We conducted a prospective study on the use of OCT in women with suspected CIN. OCT images were obtained on colposcopy from non-suspicious and suspicious areas, and were evaluated independently by two investigators and later compared with the corresponding histology. The sensitivity, specificity, negative and positive predictive values and accuracy of the new technique in identifying CIN or carcinoma were calculated. RESULTS: Of a total of 610 OCT images, 97 from suspicious areas in 60 women were compared with the corresponding histology. Sixty-three of 67 CIN lesions and four invasive carcinomas were diagnosed correctly on evaluation of the OCT images by the first observer. There were 69 true-positive, 11 true-negative, 13 false-positive and four false-negative results, giving a sensitivity of 95% and a specificity of 46%. CONCLUSION: OCT is a rapid, easy-to-use modality that provides real-time, microarchitectural information of the cervical epithelium. Further refinement of this technology will lead to OCT systems with a significantly higher resolution and may result in better differentiation of cancerous and precancerous lesions.

RESUMEN

OBJECTIVE: To compare the pelvic floor function of primiparous women to women after a second delivery regarding symptoms of urinary and anal incontinence, anal sphincter ruptures and bladder-neck mobility. METHODS: A questionnaire evaluating symptoms of urinary and anal incontinence was used in nulliparous women before and 27 months after childbirth. Furthermore these symptoms were correlated with functional changes of the pelvic floor based on a careful gynecologic examination as well as perineal and endoanal ultrasound. RESULTS: 112 nulliparous women were included, 49 women returned for follow-up on average 27 months (SD 4.4 months) after the first delivery. 39 women (group A) had just one delivery, 10 women (group B ? 10/49) had had a second delivery. Apart from levator ani muscle strength, no significant difference between pelvic floor function of group A vs group B was demonstrable. Furthermore, we could show no significant difference for symptoms of urinary (11 (28.2%) vs. 5 (50.0%)) and anal incontinence (14 (35.9%) vs. 4 (40.0%)) between both groups. However, we found a lasting increase of stress urinary and anal incontinence as well as overactive bladder symptoms after one or more deliveries. The position of the bladder neck at rest was lower in both groups compared to the position before the first delivery and bladder neck mobility increased after one or more deliveries. DISCUSSION: Our study shows several statistically significant changes of the pelvic floor function even on average 27 months after delivery, but a subsequent delivery did not compromise the pelvic floor any further.

RESUMEN

OBJECTIVE: To compare the function of the pelvic floor in primiparae before and during pregnancy with the status post partum concerning symptoms of incontinence, sphincter ruptures, bladder-neck mobility and the influence of the different modes of deliveries. METHODS: Questionnaire evaluating symptoms of urinary and anal incontinence in nulliparous women before and after delivery and correlating these symptoms with functional changes of the pelvic floor based on a careful gynaecologic examination as well as perineal and endoanal ultrasound. RESULTS: 112 women were included in our study and came for the first visit, 99 women returned for follow-up 6 months after childbirth. Stress and flatus incontinence significantly increased from before pregnancy (3 and 12%) to after childbirth (21 and 28%) in women with spontaneous delivery or vacuum extraction. No new symptoms occurred after c-section. There was no significant difference between the bladder neck position before and after delivery. The mobility of the bladder neck was significantly higher after vaginal delivery using a vacuum extraction compared to spontaneous delivery or c-section. The bladder neck in women with post partum urinary stress incontinence was significantly more mobile than in continent controls. The endoanal ultrasound detected seven occult sphincter defects without any correlation to symptoms of anal incontinence. CONCLUSION: Several statistically significant changes of the pelvic floor after delivery were demonstrated. Spontaneous vaginal delivery or vacuum extraction increases the risk for stress or anal incontinence, delivery with vacuum extraction leads to higher bladder neck mobility and stress incontinent women have more mobile bladder necks than continent women.
