Stroke unit admission is associated with better outcome and lower mortality in patients with intracerebral hemorrhage.

BACKGROUND AND PURPOSE: There is no clear consensus among current guidelines on the preferred admission ward [i.e. intensive care unit (ICU) or stroke unit (SU)] for patients with intracerebral hemorrhage. Based on expert opinion, the American Heart Association and European Stroke Organization recommend treatment in neurological/neuroscience ICUs (NICUs) or SUs. The European Stroke Organization guideline states that there are no studies available directly comparing outcomes between ICUs and SUs. METHODS: We performed an observational study comparing outcomes of 10 811 consecutive non-comatose patients with intracerebral hemorrhage according to admission ward [ICUs, SUs and normal wards (NWs)]. Primary outcomes were the modified Rankin Scale score at discharge and intrahospital mortality. An additional analysis compared NICUs with SUs. RESULTS: Treatment outside an SU was associated with higher odds for an unfavorable outcome [ICU vs. SU: odds ratio (OR), 1.27; 95% confidence interval (CI), 1.09-1.46; NW vs. SU: OR, 1.28; 95% CI, 1.08-1.52] and higher odds for intrahospital mortality (ICU vs. SU: OR, 2.11; 95% CI, 1.75-2.55; NW vs. SU: OR, 1.52; 95% CI, 1.23-1.89). A subgroup analysis of severely affected patients treated in dedicated NICUs (vs. SUs) showed that they had a lower risk of a poor outcome (OR, 0.45; 95% CI, 0.26-0.79). CONCLUSIONS: Treatment in SUs was associated with better functional outcome and reduced mortality compared with ICUs and NWs. Our findings support the current guideline recommendations to treat patients with intracerebral hemorrhage in SUs or NICUs and suggest that some patients may further benefit from NICU treatment.

Effects of home reading training on reading and quality of life in AMD-a randomized and controlled study.

BACKGROUND: Age-related macular degeneration (AMD) causes reading impairment, reduced quality of life (QoL), and secondary depression. We have shown that support with magnifying aids improved reading speed (RS), emotional and cognitive status, and QoL. The present study investigates whether additional reading training (RT) (after adapting to appropriate visual aids) can further improve vision rehabilitation. METHODS: Patients with dry AMD were randomly assigned to 2 groups. The primary RT group (P-RTG, n = 25) trained with sequentially presented text (RSVP), and the control group (CG, n = 12) performed placebo training (crossword puzzles) and later crossed over to RT, so that altogether 37 participants performed reading training. Patients trained at home on a PC for 6 weeks. RS was assessed during reading printed paragraphs of text aloud. Using a scanning laser ophthalmoscope, we examined fixation stability and preferred retinal locus (PRL) for fixating a cross, as well as PRL and eye movements during reading single words. We assessed emotional status by Montgomery-Åsberg Depression Rating Scale (MADRS), cognitive status by dementia detection test ( DemTect ) and QoL by Impact of Vision Impairment (IVI) profile. Visual acuity and magnification requirement were examined by standard procedures. All variables were measured before and after placebo training, before and after RT, and after 6 weeks without training (follow-up). RESULTS: RS improved significantly in the P-RTG during RT, but not in the CG during placebo training. The effect remained stable at follow-up. Fixation performance and eye movement variables did not change. Emotional status (MADRS) improved in P-RTG during RT and showed a significant difference of the change of scores between the 2 groups. Complete IVI scores improved significantly during RT and remained stable. CONCLUSION: The results indicate that patients with AMD, who already use magnifying aids, benefit from additional RT and that it can contribute in preventing depression and improve QoL. TRIAL REGISTRATION: The study was registered at the German Clinical Trials Register (DRKS00015609).

Time trends in incidence and mortality of cutaneous melanoma in Germany.

OBJECTIVES: To characterize incidence and mortality trends of cutaneous melanoma (CM) in Germany to extrapolate these data until 2030. METHODS: We evaluated data from the Centre for Cancer Registry Data (1999-2012) and from the Saarland Cancer Registry (1970-2012). Age-standardized (according to the European Standard Population, WHO 1976) incidence and mortality rates [age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs)] and crude incidence and mortality rates [crude incidence rates (CIRs) and crude mortality rates (CMRs)] were analysed. RESULTS: In entire Germany, ASIRs increased by 55% to 19.2 and CIRs by 77% to 26.0 new cases per 100 000 from 1999 to 2012. ASMRs remained stable, whereas CMR increased by 58% to 4.1 for males and by 30% to 3.0 for females per 100 000. In the Federal State of Saarland, ASIRs increased more than four-fold to 13.1, CIRs increased six-seven fold to 18.5/100 000 from 1970 to 2012. In the same period, ASMRs increased three-fold in males and two-fold in females to 2.5 and 1.6, whereas CMRs increased 5.5-fold in males and 3.5-fold in females to 3.9 and 3.2/100 000, mainly caused by steep increases of CIRs and CMRs in age groups ≥60 years. Projected CIRs will rise to 44-46 for males and 38-40 for females in 2030. Steepest increases were extrapolated for patients ≥60 years, especially for males, but are also expected for age groups of 40-59 years. In contrast, CIRs are anticipated to stabilize for subjects <40 years. CONCLUSIONS: There is a constant increase in incidence and mortality rates for CM in Germany. As the German population is ageing and the current population has already accumulated high levels of UV exposure, a further increase in melanoma incidence is projected for the future without signs of levelling-off.

Age-corrected hearing loss after chemoradiation in cervical cancer patients.

OBJECTIVE: This study aimed to evaluate subjective and objective hearing loss in cervical cancer patients after chemoradiation with cisplatin (mono). PATIENTS AND METHODS: A total of 51 cervical cancer patients with indication for chemoradiation were included. Pure tone and impedance audiometry were performed before and after chemoradiation. Hearing loss was scaled according to ASHA criteria. Subjective hearing was assessed with the Oldenburger Sentence Test. To consider age-dependent changes, hearing loss was corrected for age and the time interval between measurements. RESULTS: Median age at diagnosis was 46 years, 46% were active/former smokers (n = 24), 28 (54%) patients were never-smokers. Median total weekly cisplatin dose was 70 ± 14.2 mg. Cumulative doses of cisplatin during chemoradiation ranged between 115.2 and 400 mg cisplatin (mean 336.1 mg, median 342 ± 52.7 mg). The median interval between last chemotherapy and second audiometry was 320 ± 538 days (35-2262 days). Changes in hearing threshold ≥20 dB were experienced by 32/52 patients (62%) following chemoradiation, 55% of them for frequencies ≥6000 Hz. No statistically significant hearing loss remained after chemoradiation upon correction for age and time interval. Patients >40 years had a higher risk of hearing loss than younger patients. Objective data on hearing function did not correlate with subjective hearing loss and did not impair daily activity in any patient. CONCLUSION: Chemoradiation with cumulative cisplatin doses up to 400 mg did not lead to significant impairment of objective or subjective hearing. For cervical cancer patients undergoing chemoradiation, standard audiometry is not indicated.

Age, burnout and physical and psychological work ability among nurses.

Background: The ageing of the US labour force highlights the need to examine older adults' physical and psychological ability to work, under varying levels of occupational burnout. Aims: To examine how age and burnout interact in predicting physical and psychological work ability. Methods: Using a cohort of actively working nurses, we assessed factors on the Work Ability Index at 12-month follow-up and determined how these were related to age and exhaustion-related burnout at baseline. Results: The study group consisted of 402 nurses aged 25-67 (mean = 41.7). Results indicated age by burnout interactions in which decrements in physical work ability with greater age were observed at all but the lowest level of burnout (1.5 SD below mean: ß = -0.14, 95% CI -0.36, 0.07; 1 SD below: ß = -0.23, 95% CI -0.39, -0.06; mean: ß = -0.39, 95% CI -0.50, -0.29; 1 SD above: ß = -0.56, 95% CI -0.70, -0.42; 1.5 SD above: ß = -0.64, 95% CI -0.83, -0.46). In contrast, we observed decrements in psychological work ability with age at higher levels of burnout only (1 SD above: ß = -0.20, 95% CI -0.35, -0.05; 1.5 SD above: ß = -0.30, 95% CI -0.49, -0.11); at lower levels of burnout, older age was associated with improvements in this (1 SD below: ß = 0.19, 95% CI 0.03, 0.35; 1.5 SD below: ß = 0.29, 95% CI 0.08, 0.50). Conclusions: Findings indicated physical and psychological dimensions of work ability that differed by age and occupational burnout. This emphasizes the need for interventions to reduce burnout and to address age-related strengths and vulnerabilities relating to physical and psychological work ability.

The Angioedema Quality of Life Questionnaire (AE-QoL) - assessment of sensitivity to change and minimal clinically important difference.

BACKGROUND: The Angioedema Quality of Life Questionnaire (AE-QoL) has recently been developed and validated as the first specific patient-reported outcome tool to assess quality of life (QoL) impairment in recurrent angioedema patients. As of yet, its sensitivity to change and minimal clinically important difference (MCID) have not been established. METHODS: Recurrent angioedema patients with chronic spontaneous urticaria or hereditary angioedema were repeatedly asked to complete the AE-QoL along with the SF-12 and other anchors for QoL impairment and disease activity during routine care visits. The sensitivity to change of AE-QoL was determined by correlating changes in its scores over time with changes in the applied anchors. In addition, the MCID was determined using anchor-based and distributional criterion-based approaches. RESULTS: Two hundred and seventy-eight patients contributed data sets for analysis. Baseline AE-QoL values were found to correlate well with SF-12 results as well as all other applied anchors for angioedema-related QoL impairment and disease activity. In addition, AE-QoL score changes over time correlated significantly with changes in the above anchors, thus demonstrating its sensitivity to change. The MCID of the AE-QoL total score was found to be six points. CONCLUSION: The AE-QoL is a valuable tool to assess changes of QoL impairment in recurrent angioedema patients over time, including changes due to treatment.

Development and validation of the mastocytosis quality of life questionnaire: MC-QoL.

BACKGROUND: Mastocytosis is a heterogeneous disease characterized by a clonal expansion of mast cells in various organs. The vast majority of patients affected suffer from signs and symptoms caused by mediator release from mast cells. Although the disease burden is high, there is currently no specific instrument to measure health-related quality of life (HRQoL) impairment in patients with mastocytosis. OBJECTIVE: The aim of this study was to develop and validate a disease-specific tool to assess HRQoL impairment in patients with cutaneous and indolent systemic mastocytosis, the Mastocytosis Quality of Life Questionnaire (MC-QoL). METHODS: Sixty-two potential MC-QoL items were developed in a combined approach consisting of semi-structured patient interviews, expert input and literature research. Item selection was performed by impact analysis with 76 patients and a final review for face validity. The resulting MC-QoL was tested for validity, reliability and influence factors. In parallel, an US American-English version of the MC-QoL was developed. RESULTS: A total of 158 patients (41 CM, 41 MIS and 76 ISM) took part in the MC-QoL validation study. The final 27-item questionnaire was found to have a four-domain structure ('symptoms', 'emotions', 'social life/functioning' and 'skin'), a valid total score and an excellent test-retest reliability. Multiple regression analysis revealed disease duration, but not age, gender or skin involvement to be a significant determinant of HRQoL impairment in mastocytosis. CONCLUSIONS: The MC-QoL is the first disease-specific HRQoL questionnaire for adult patients with cutaneous and indolent systemic mastocytosis. This short, validated and reliable instrument will serve as a valuable tool in future clinical studies and in routine patient care.

Frequency and predictors of acute ischaemic lesions on brain magnetic resonance imaging in young patients with a clinical diagnosis of transient ischaemic attack.

BACKGROUND AND PURPOSE: Acute lesions in patients with transient ischaemic attack (TIA) are important as they are associated with increased risk for recurrence. Characteristics associated with acute lesions in young TIA patients were therefore investigated. METHODS: The sifap1 study prospectively recruited a multinational European cohort (n = 5023) of patients aged 18-55 years with acute cerebrovascular event. The detection of acute ischaemic lesions was based on diffusion-weighted imaging (DWI). The frequency of DWI lesions was assessed in 829 TIA patients who met the criteria of symptom duration <24 h and their association with demographic, clinical and imaging variables was analysed. RESULTS: The median age was 46 years (interquartile range 40-51 years); 45% of the patients were female. In 121 patients (15%) ≥1 acute DWI lesion was detected. In 92 patients, DWI lesions were found in the anterior circulation, mostly located in cortical-subcortical areas (n = 63). Factors associated with DWI lesions in multiple regression analysis were left hemispheric presenting symptoms [odds ratio (OR) 1.92, 95% confidence interval (CI) 1.27-2.91], dysarthria (OR 2.17, 95% CI 1.38-3.43) and old brain infarctions on MRI (territories of the middle and posterior cerebral artery: OR 2.43, 95% CI 1.42-4.15; OR 2.41, 95% CI 1.02-5.69, respectively). CONCLUSIONS: In young patients with a clinical TIA 15% demonstrated acute DWI lesions on brain MRI, with an event pattern highly suggestive of an embolic origin. Except for the association with previous infarctions there was no clear clinical predictor for acute ischaemic lesions, which indicates the need to obtain MRI in young individuals with TIA.

Intraoperative transfusion practices in Europe.

BACKGROUND: Transfusion of allogeneic blood influences outcome after surgery. Despite widespread availability of transfusion guidelines, transfusion practices might vary among physicians, departments, hospitals and countries. Our aim was to determine the amount of packed red blood cells (pRBC) and blood products transfused intraoperatively, and to describe factors determining transfusion throughout Europe. METHODS: We did a prospective observational cohort study enrolling 5803 patients in 126 European centres that received at least one pRBC unit intraoperatively, during a continuous three month period in 2013. RESULTS: The overall intraoperative transfusion rate was 1.8%; 59% of transfusions were at least partially initiated as a result of a physiological transfusion trigger- mostly because of hypotension (55.4%) and/or tachycardia (30.7%). Haemoglobin (Hb)- based transfusion trigger alone initiated only 8.5% of transfusions. The Hb concentration [mean (sd)] just before transfusion was 8.1 (1.7) g dl(-1) and increased to 9.8 (1.8) g dl(-1) after transfusion. The mean number of intraoperatively transfused pRBC units was 2.5 (2.7) units (median 2). CONCLUSION: Although European Society of Anaesthesiology transfusion guidelines are moderately implemented in Europe with respect to Hb threshold for transfusion (7-9 g dl(-1)), there is still an urgent need for further educational efforts that focus on the number of pRBC units to be transfused at this threshold. CLINICAL TRIAL REGISTRATION: NCT 01604083.

[The Rostock Headache Questionnaire ("Rokoko")--validation of a tool to screen and to qualify primary headaches]. / Der Rostocker Kopfschmerzfragen-Komplex ("Rokoko")--Validierung einer schnellen diagnostischen Hilfe bei der Einordnung primärer Kopfschmerzen.

Primary headache disorders should be diagnosed based on the detailed history of the patient. However, only few questions are necessary to allocate the symptoms to migraine, tension-type headache or other primary headaches in most cases. The "Rostock Headache Questionnaire" (Rokoko) is suitable for being completed by the investigator or the patient him/herself within a few minutes. Validation parameters of a sample of n = 87 patients (median: 44 years), diagnosed by headache experts in a personal interview ("gold standard"), are presented. Sensitivity and specificity for migraine without aura (0.87/0.51), migraine with aura (0.71/0.95), tension-type headache (0.57/0.93), or a combination of both (0.22/0.93) are based on the parameters pain frequency (recurrent vs. permanent), and the presence or absence of aura symptoms. To differentiate tension-type headache into episodic or chronic forms, the questionnaire can be analysed individually based on the frequency of headache days. The questionnaire enables the fast acquisition of relevant data in headache diagnosis and headache research with sufficient sensitivity and specificity. In addition, further information about triggering and symptoms of headaches can be assessed. The questionnaire can be used both by neurologists or psychiatrists and by general practitioners. The questionnaire does not replace the physical examination.

Vertical and horizontal reading training in patients with hemianopia and its effect on reading eye movements.

Vertical reading training (VRTr) increases reading speed (RS) significantly in patients with hemianopic field defects (HFD). We ask, how eye movements (EM) contribute to this improvement and whether EM-behavior is affected by the side of HFD. Twenty-one patients, randomly assigned to VRTr or horizontal RTr, trained reading single lines from a screen at home, for 4 weeks. In the clinic, we recorded EM while reading short sentences aloud from a screen before training (T1), directly (T2) and 4 weeks afterwards (T3). RS-screen was correlated with RS during reading printed paragraphs (RS-print) to assess the transfer to everyday life. RS-screen and RS-print correlated positively (horizontal: r > 0.8, vertical: r > 0.9) at all times. Vertical RS did not exceed horizontal RS. We found significant negative correlations of EM-variables and RS-print: in right-HFD with the number of forward saccades (T1: r = - 0.79, T2: r = - 0.94), in left-HFD with the steps during return sweeps (T1: r = - 0.83, T2: r = - 0.56). Training effects remained stable at T3. EM-improvement was specific for the RTr and the side of the HFD: in right-HFD fewer forward saccades after VRTr, in left-HFD fewer steps during return sweeps after HRTr. RTr on a screen transfers to reading printed text in real-life situations.Trial registration: The study was retrospectively registered in the German Clinical Trials register: DRKS-ID: DRKS00018843, March 13th, 2020.

NIH-defined graft-versus-host disease and evidence for a potent graft-versus-leukemia effect in patients with acute lymphoblastic leukemia.

BACKGROUND: The prognostic value of the NIH consensus criteria for graft-versus-host disease (GVHD) is not well defined yet. PATIENTS AND METHODS: We analyzed NIH-defined GVHD in 147 acute lymphoblastic leukemia (ALL) patients. RESULTS: The cumulative incidence of classic acute GVHD (aGVHD), late aGVHD and chronic GVHD (cGVHD) was 63%, 12% and 41%, respectively. cGVHD was subclassified as classic versus overlap syndrome in 40% versus 60% of cases. In multivariate Cox regression analysis with GVHD as time-dependent covariate, classic aGVHD grade III/IV had a negative impact on overall survival (OS) due to higher non-relapse mortality. cGVHD of any grade was associated with superior OS, which was due to lower relapse incidence. Classic cGVHD versus overlap syndrome had no differential impact. In 44 patients without GVHD after transplant who received donor lymphocyte infusions (DLI), the cumulative incidence of classic aGVHD, late aGVHD or cGVHD was 60%, 5% and 57%. Occurrence of cGVHD after DLI was associated with improved OS due to lower relapse incidence. CONCLUSIONS: The NIH consensus criteria for GVHD clearly define prognostic subgroups in patients transplanted for ALL. The improved OS in patients developing cGVHD after transplant or DLI gives clear evidence for a potent graft-versus-leukemia effect in this indication.

Development, validation, and initial results of the Angioedema Activity Score.

BACKGROUND: Recurrent angioedema (RecA) is a frequent clinical problem characterized by suddenly occurring cutaneous and/or mucosal swellings. Depending on their location, RecA may be painful, hindering, disfiguring, or even life-threatening. The assessment of disease activity in affected patients is important to guide treatment decisions. Currently, however, there is no standardized and validated outcome measure available to do so. OBJECTIVE: To develop and validate the first specific patient-reported outcome instrument to assess disease activity in RecA patients, the Angioedema Activity Score (AAS). METHODS: After a set of potential AAS items was developed, item evaluation and reduction were performed by means of impact analysis, factor analysis, regression analysis, and by checking for face validity. In addition, the items of the final AAS questionnaire were tested for their validity and reliability during a 12-week validation study. RESULTS: In total, data from 110 and 80 RecA patients were used during the AAS item evaluation and validation phase, respectively. The resulting AAS consisted of five items and was found to have a one-dimensional structure and excellent internal consistency. It correlated well with other measures of disease activity and quality-of-life impairment, thus demonstrating its convergent validity. In addition, the known-groups validity and test-retest reliability of the AAS were found to be good. CONCLUSIONS: The AAS is the first validated and reliable tool to determine disease activity in RecA patients, and it may serve as a valuable instrument in future clinical studies and routine patient care.

Rupatadine improves quality of life in mastocytosis: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Mastocytosis is frequently associated with mast cell-mediated symptoms which require relieving medication. While second generation antihistamines (sgAHs) are the first line therapeutic strategy to treat mast cell mediator-related symptoms, controlled clinical trials on how they improve quality of life have not been performed. METHODS: This randomized, double-blind, placebo-controlled, cross-over trial assessed rupatadine 20 mg daily in the treatment of mastocytosis symptoms in 30 adult patients. Symptoms were assessed by a visual analogue scale (VAS) and symptom specific quality of life questionnaire (ItchyQoL). RESULTS: The mean ItchyQoL total score and VAS symptom score were significantly improved in the rupatadine treatment phase compared with placebo. There were also significant reductions from placebo in the severity of itch, wheal and flare, flushing, tachycardia and headache but not gastrointestinal symptoms. CONCLUSIONS: In this first comprehensive trial of a sgAH in mastocytosis, rupatadine 20 mg daily for 4 weeks significantly controlled symptoms and improved patients' quality of life.

[The importance of pathology in the German prostate cancer study PREFERE]. / Die Bedeutung der Pathologie in der deutschen Prostatakrebsstudie PREFERE.

Prostate cancer is the most common carcinoma of elderly males and holds the third place in the ranking of cancer-specific mortality. However, total mortality rate of 3 % is low and half of the patients die from other diseases, which is for the most part due to significantly improved diagnostic methods and the increasing use of prostate-specific antigen (PSA) screening. This has led to a stage migration towards early tumor stages that are prognostically heterogeneous and require differentiated treatment. The German and European guidelines recommend four therapy options (i.e. radical prostatectomy, percutaneous irradiation, permanent seed implantation and active surveillance) for localized prostate cancer and from contemporary study data it is unclear which therapy is most beneficial. This will be the subject of the PREFERE trial, a prospective randomized multicentre trial which plans to recruit 7,600 patients and to observe them over a period of up to 17 years. The histopathological diagnosis of the primary biopsy plays a crucial role in the inclusion criteria, as this article outlines in detail.

Prognostic impact of meningeal dissemination in primary CNS lymphoma (PCNSL): experience from the G-PCNSL-SG1 trial.

BACKGROUND: We evaluated the frequency and prognostic impact of meningeal dissemination (MD) in immunocompetent adult patients with primary central nervous system lymphoma treated in a randomized phase III trial. PATIENTS AND METHODS: MD was evaluated at study entry and defined by lymphoma proof in the meningeal compartment detected by at least one of the following methods: cerebrospinal fluid (CSF) cytomorphology, detection of clonal B cells by IgH PCR in CSF or contrast enhancement of the leptomeninges on magnetic resonance imaging (MRI). RESULTS: Data on MD were available in 415 patients, of those, MD was detected in 65 (15.7%): in 44/361 (12.2%) by CSF cytomorphology, in 16/152 (10.5%) by PCR and in 17/415 (4.1%) by MRI. Major patients' characteristics and therapy did not significantly differ between patients with MD (MD+) versus those without MD (MD-). There was a significant correlation of MD with CSF pleocytosis (>5/µl; P < 0.0001), but no correlation with CSF protein elevation (>45 mg/dl). Median progression-free survival was 6.7 months [95% confidence interval (CI) 0-14.5] in MD+ and 8.3 months (5.7-10.8) in MD- patients (P = 0.95); median overall survival was 21.5 months (95% CI 16.8-26.1) and 24.9 months (17.5-32.3), respectively (P = 0.98). CONCLUSION: MD was detected infrequently and had no impact on outcome in this trial.

Development and construct validation of the angioedema quality of life questionnaire.

BACKGROUND: Recurrent angioedema is a frequent clinical problem characterized by unpredictably and rapidly occurring cutaneous and mucosal swellings. These swellings may be painful and/or disfiguring. Upper airway involvement can also lead to dyspnea and suffocation. Although the disease burden is high, there is currently no specific instrument to measure health-related quality of life (QoL) impairment. OBJECTIVE: To develop and validate the first symptom-specific tool to assess QoL impairment in recurrent angioedema patients, adhering to established methodological recommendations. METHODS: During the development phase, 29 questions (items) were generated. Subsequently, item reduction was performed by means of impact analysis and factor analysis as well as by checking for content and face validity. As a result, 17 items were selected and included in the final instrument, the Angioedema QoL Questionnaire (AE-QoL). AE-QoL was then tested for its validity, reliability, and influence factors. RESULTS: One hundred and ten angioedema patients took part in the validation of AE-QoL. AE-QoL was found to have a four-dimensional structure as well as a valid total score. All of its four domains (functioning, fatigue/mood, fears/shame, food) showed good levels of internal consistency with Cronbach's alpha > 0.8. Test-retesting revealed a good reliability of the instruments total score and domain scores. Gender as well as the patients' self-rated disease activity was found to be predictors of the AE-QoL total score. CONCLUSIONS: Angioedema Quality of Life Questionnaire is the first angioedema-specific QoL questionnaire. It is a short, valid and reliable instrument that may serve as a valuable tool in future clinical studies and in routine patient care.

Critical temperature threshold measurement for cold urticaria: a randomized controlled trial of H(1) -antihistamine dose escalation.

BACKGROUND: Cold urticaria is a rare but severe and potentially lethal condition. It is primarily treated symptomatically with H(1) -antihistamines. However, patients have a variable response to these drugs and, to date, it has not been possible to predict readily the response to therapy of individual patients. OBJECTIVES: To assess the severity of the cold urticaria in naive patients and the response to therapy of patients treated with increasing doses of an H(1) -antihistamine by measurement of critical temperature thresholds (CTT) for producing weals on the forearm. METHODS: This was a two-centre, hospital-based, double-blind, randomized, parallel-group study of patients with a confirmed diagnosis of cold urticaria of at least 6 months' duration. Patient groups received either a constant dose of desloratadine 5 mg daily for 6 weeks (n = 13), or escalating doses of desloratadine: 5 mg daily for the first 2 weeks, 10 mg daily for the second 2 weeks and 20 mg daily for the final 2 weeks (n = 15). Only one adverse event that appeared to be drug related was reported: mild fatigue after treatment with desloratadine 10 mg that lasted for about 3 weeks and resolved at the end of the study. RESULTS: The desloratadine 5 mg daily dose produced a submaximal reduction of mean CTT which remained relatively constant over 6 weeks. Dose escalation increased efficacy, the reduction in mean CTT at four-times the standard daily dose being significantly greater (P = 0·03) than with the standard dose. Individually, no patient became symptom free (CTT < 4 °C) on 5 mg, while two became symptom free on 10 mg and a further three on 20 mg desloratadine daily. CONCLUSIONS: Measurement of CTT allows for individualized risk management and therapy in patients with cold urticaria.

A German multicenter, randomized phase III trial comparing irinotecan-carboplatin with etoposide-carboplatin as first-line therapy for extensive-disease small-cell lung cancer.

BACKGROUND: This trial was designed to prove superiority of irinotecan over etoposide combined with carboplatin in extensive-disease small-cell lung cancer. PATIENTS AND METHODS: Patients were randomly assigned to receive carboplatin area under the curve 5 mg x min/ml either in combination with irinotecan 50 mg/m2 on days 1, 8, and 15 (IP) or etoposide 140 mg/m2 on days 1-3 (EP). Primary end point was progression-free survival (PFS) at 6 months. Secondary end points were overall survival (OS), response rate, and toxicity. RESULTS: Of 226 patients, 216 were eligible. Median PFS was 6.0 months [95% confidence interval (CI) 5.0-7.0] in the IP arm and 6.0 months (95% CI 5.2-6.8) in EP arm (P = 0.07). Median survival was 10.0 months (95% CI 8.4-11.6) and 9.0 months (95% CI 7.6-10.4) in the IP and EP arm (P = 0.06), respectively. Hazard ratios for disease progression and OS were 1.29 (95% CI 0.96-1.73, P = 0.095) and 1.34 (95% CI 0.97-1.85, P = 0.072), respectively. No difference in response rates was observed. Grade 3 and 4 hematologic toxicity favored the IP arm, whereas diarrhea was significantly more frequent in the IP arm. CONCLUSION: This trial failed to show superiority of irinotecan over etoposide in combination with carboplatin.

Proposal for a new grading of Moyamoya disease in adult patients.

BACKGROUND: Moyamoya disease (MMD) is graded based on digital subtraction angiography (DSA) with limited clinical applications. The aim was to identify clinically relevant parameters that may be used to develop a novel MMD grading system. METHODS: In 40 MMD patients bilateral revascularization surgery was performed. Clinical data including DSA, MRI and regional cerebral blood flow studies were assessed. χ(2) test corrected for dependency of measurements at the same subject and analysis of receiver operating characteristics were used to identify key parameters. Grading system included: DSA (stenosis/occlusion = 1 point; stenosis/occlusion + intracranial compensation = 2 points; stenosis/occlusion + intracranial compensation + extra-intracranial compensation = 3 points), MRI (no sign of ischemia = 0 points; signs of ischemia = 1 point) and cerebrovascular reserve capacity (CVRC > -5% = 0 points; CVRC < -5% = 2 points). MMD grade I referred to 1-2 points, grade II to 3-4 and grade III to 5-6 points. RESULTS: DSA, MRI and CVRC were dependent factors associated with the occurrence of clinical symptoms. Receiver operating characteristics analysis indentified the grading system as superior to each single parameter in predicting clinical symptoms. Fourteen hemispheres were graded as mild (grade I), 35 as moderate (grade II) and 31 as severe (grade III); 21% of grade I, 63% of grade II and 93% of grade III hemispheres were clinically symptomatic. CONCLUSIONS: The proposed grading system allows to stratify for clinical symptomatology in MMD patients. Future studies will have to investigate its value for assessing clinical symptoms and treatment risks.
