Cetirizine inhibits gender-specific blood cell dynamics upon allergen contact in allergic rhinitis.

IgE-mediated inflammatory responses upon allergen contact in allergic rhinitis (AR) are associated with rapid alterations of circulating blood cell numbers detectable in a complete blood count (CBC). Aim of this study was to evaluate whether intake of antihistamines may modulate allergen-induced CBC dynamics in male and female patients. A total of N = 112 specific allergen challenges were performed in otherwise healthy AR subjects. Seventy-two (n = 72) subjects received placebo and forty (n = 40) received cetirizine (H1-receptor antagonist) per os prior to allergen exposure in a randomized, double-blind trial at the Vienna Challenge Chamber (VCC); a subgroup of twenty-five (n = 25) subjects received cetirizine and placebo on different study days (parallel group). Blood samples and symptom scores were taken at baseline and immediately after 6 h of airway challenge simulating ambient allergen contact. Female sex was associated with a pronounced circulating monocyte increase (p < .01) and male sex with an eosinophil decrease (p < .05) in the placebo group, but not in cetirizine treated subjects. The significant increase in segmented neutrophils (p < .001) and decrease in circulating erythrocytes (p < .01) upon allergen challenge was less prominent after cetirizine intake in both sexes. A more prominent thrombocyte increase in female subjects (p < .05) was noted upon allergen exposure, regardless of prior cetirizine intake. Cetirizine inhibited the mobilization of neutrophils, lymphocytes and decline in erythrocyte numbers, but did not affect thrombocyte increase upon allergen challenge. It further diminished gender-specific blood cell dynamics. Overall, as reflected in a simple CBC, cetirizine critically diminished immediate and late innate immune responses subsequent to allergen exposure.

Effects of a lower extremity exercise program on gait biomechanics and clinical outcomes in children and adolescents with obesity: A randomized controlled trial.

BACKGROUND: Research highlights the detrimental effects of obesity on gait biomechanics and the accompanied risk of lower-extremity skeletal malalignments, increased joint stress, pain and discomfort. Individuals with obesity typically show increased knee valgus angles combined with an increased step width. Accompanying muscular dysfunctions impede their ability to compensate for these alterations, especially in the frontal plane. To date, no studies are available, which evaluated the potential effects of an exercise program (EP) in reducing these unfavorable biomechanical changes. RESEARCH QUESTIONS: Is a 12-week EP, which includes hip abductor and knee extensor strength exercises and fosters dynamic knee alignment, effective in positively altering gait biomechanics in children and adolescents with obesity? METHODS: This study was a randomized controlled trial having children and adolescents with obesity assigned to an EP (n = 19) or control (n = 16) group. Pain, self-rated knee function, muscle strength and 3D gait analysis during walking and stair climbing were evaluated. RESULTS: Results indicate that the EP was able to increase muscular strength especially in the hip abductors. In addition, children from the EP group walked with less maximum hip adduction and reduced pelvic drop during weight acceptance at follow-up. No changes were present in self-rated knee function, pain or discomfort. SIGNIFICANCE: Even though effects were small, results indicate that an EP is an effective short-term possibility to counteract the progressive development of biomechanical malalignments of the lower extremity. Clinical parameters indicated that the program was feasible. Nonetheless, low adherence highlights the need to develop more attractive programs. CLINICAL TRIALS REG.

[Pain therapy for children and adolescents with hemophilia : Recommendations by an expert panel]. / Schmerztherapie bei Kindern und Jugendlichen mit Hämophilie : Handlungsempfehlungen einer Expertengruppe.

BACKGROUND: Children and adolescents with severe hemophilia commonly suffer from acute and chronic pain as a consequence of hemophilia-related bleeding. Intervention-related pain also plays a major role. Despite its high prevalence in this patient group, hemophilia-related pain is not always adequately addressed and sufficiently treated. OBJECTIVES: This paper discusses how to improve pain management for children and adolescents (0-18 years) with hemophilia and which specific features in this population should influence decisions in pain management. MATERIALS AND METHODS: An expert panel discussed challenges in pain treatment in children and adolescents with hemophilia. Recommendations are based on evidence and clinical experience. RESULT: Pain management in children with hemophilia needs improvement. Children with hemophilia are at risk of developing chronic pain and of suffering traumatization due to insufficient pain management. Pain therapy can be challenging in these children as both their age and the underlying disease limit the options in particular in pain medication. The expert panel developed recommendations to improve pain management in children with hemophilia.

A novel mechanotronic orthosis enables symmetrical gait kinematics in a patient with a femoral nerve palsy - a case study.

The usage of stance- and swing-phase control orthoses (SSCOs) is a good option in patients with neuromuscular insufficiency of the quadriceps muscle in a broad range of musculo-skeletal disorders. The subjective sensation of improved mobility in daily life and walking comfort could be objectively confirmed by the ability to walk without crutches and by harmonization of the gait patterns in hip and knee. They could also be a considered mobility device after limb salvage surgery, which may even have an impact on preoperative decision making. IMPLICATIONS FOR REHABILITATION Symmetric gate in spite of femoral nerve palsy. Early gate improvements even after hours. High patient?s motivation to use the device.

The course of quality of life and neurocognition in newly diagnosed patients with glioblastoma.

BACKGROUND: The importance of QoL and neurocognitive functions in patients with glioblastoma (GB) is above controversy by now. We followed newly diagnosed GB patients treated with radio-chemotherapy during their course of disease by continuously evaluating their quality of life (QoL) and cognitive functions. METHODS: We included consecutive patients with newly diagnosed GB from 2010 to 2013 at the Medical University of Vienna. To assess QoL the EORTC QLQ C30 and BN20 questionnaire were used. Neurocognition was measured with the NeuroCog FX. The evaluations were done 6 times every three months, beginning at the beginning of radio-chemotherapy. RESULTS: 42 patients participated in this study. We also recorded QoL and neurocognition in 23 patients after the first disease progression. Patients maintained their cognitive summary score until relapse. Patients with left-sided tumors showed significant lower scores in the subscale verbal fluency than patients with right-sided tumors. The global health score of QoL decreased after the fifth evaluation (13months after diagnosis) whereas a peak of fatigue symptoms was obtained at the third evaluation. Furthermore, fatigue symptoms increased strongly 7months after diagnosis and patients' financial difficulties were mentioned more frequently by younger patients and in patients with lower education levels. CONCLUSIONS: QoL and cognitive long-term assessments are feasible also in some patients with GB after a symptomatic progression. Our study demonstrates maintenance of QoL and cognitive summary scales before tumor progression. Moreover, it highlights subgroups according to tumor location and socioeconomic factors.

Effects of resistance exercise in prostate cancer patients: a meta-analysis.

PURPOSE: The aim of the present meta-analysis was to quantify effects of resistance exercise (RE) on physical performance and function, body composition, health-related quality of life (HRQoL), and fatigue in patients with prostate cancer. METHODS: Trial data were obtained from the databases PubMed, MEDLINE, EMBASE, SCOPUS, and the Cochrane Library as of inception to 31st of December 2016. Thirty-two trials with 1199 patients were included. Results that were measured by using the same assessment method in five or more of the original studies were pooled in a meta-analysis. RESULTS: Pooled studies showed significant improvements of muscular strength in the upper and lower body (95% CI [2.52, 7.97] kg; p < 0.001 and 95% CI [10.51, 45.88] kg; p = 0.008, respectively) after RE. Furthermore, significant improvements were seen for body composition (body fat percentage 95% CI [-0.79, -0.53] %; p < 0.001; lean body mass 95% CI [0.15, 1.84] %; p = 0.028; trunk fat mass 95% CI [-0.73, -0.08] kg; p = 0.024). Additionally, the improvement of the 400-m walk time was significant (95% CI [-21.55, -14.65] s; p < 0.001). Concerning fatigue and HRQoL, there were not sufficient data for analysis. CONCLUSIONS: RE seems to be a promising approach in order to counteract loss of muscle mass, muscle strength, and physical performance in patients suffering from prostate cancer and its treatment-related side effects. RE should play part in interdisciplinary cancer rehabilitation and care of this patient group. Nevertheless, further research should investigate RE further to determine which protocols are the most pragmatic, yet yielding best patient outcomes.

Resistance exercise and secondary lymphedema in breast cancer survivors-a systematic review.

PURPOSE: The aim of the present review was to determine effects of strength exercise on secondary lymphedema in breast cancer patients. METHODS: Research was conducted by using the databases PubMed/Medline and Embase. Randomized controlled trials published from January 1966 to May 2015 investigating the effects of resistance exercise on breast cancer patients with or at risk of secondary lymphedema in accordance with the American College of Sports Medicine exercise guidelines for cancer survivors were included in the present study. RESULTS: Nine original articles with a total of 957 patients met the inclusion criteria. None of the included articles showed adverse effects of a resistance exercise intervention on lymphedema status. In all included studies, resistance exercise intensity was described as moderate to high. CONCLUSIONS: Strength exercise seems not to have negative effects on lymphedema status or might not increase risk of development of lymphedema in breast cancer patients. Further research is needed in order to investigate the effects of resistance exercise for patients suffering from lymphedema.

The effects of resistance exercise on physical performance and health-related quality of life in prostate cancer patients: a systematic review.

PURPOSE: Physical exercise has been shown to be an effective, safe, and quite inexpensive method to reduce cardiovascular and metabolic risk factors and is currently in the process of establishing its relevance for cancer specific morbidity and mortality. The aim of this systematic review was to focus on specific effects of resistance exercise (RE) in the adjuvant therapy and rehabilitation of prostate cancer patients (PCaPs) receiving or having received androgen deprivation therapy (ADT). METHODS: A systematic literature search focusing on relevant and peer-reviewed studies published between 1966 and September 2014, using PubMed, EMBASE, MEDLINE, SCOPUS, and Cochrane Library databases, was conducted. RESULTS: The majority of studies demonstrated RE as an effective and safe intervention to improve muscular strength and performance, fatigue and quality of life (QoL) in PCaPs, while there is inconclusive evidence concerning cardiovascular performance, body composition, blood lipids, bone mineral density (BMD), and immune response. CONCLUSION: Existing evidence leads to the conclusion that RE seems to be a safe intervention in PCaPs with beneficial effects on physical performance capacity and QoL. Nevertheless, further research in this field is urgently needed to increase understanding of exercise interventions in PCaPs.

A systematic review on the effectiveness of medical training therapy for subacute and chronic low back pain.

Medical training therapy (MTT) to improve muscular strength and endurance follows evidence based guidelines and is increasingly recommended to patients suffering from subacute and chronic back pain (LBP). This study investigated whether MTT was effective in reducing pain and improving function in patients with subacute or chronic LBP. Data sources were MEDLINE, EMBASE, CINAHL, Pedro, Cochrane Central Register of Controlled Trials. We included RCTs that examined exercise or MTT in adult patients with LBP compared to placebo, no intervention or other interventions. Study outcomes had to include at least one of the following: pain intensity; functional status, absenteeism. Two independent reviewers performed quality assessment. Visual analogue scale ratings ranging from 0-10 MTT quantified the MTT aspects of the intervention. Studies with rating scores >7.5 were included. We identified only 2 studies that examined the effectiveness of MTT. Both trials, one was of high quality, found MTT to decrease pain and improve function significantly better than therapy of uncertain effectiveness. There is moderate evidence that would support the effectiveness of MTT in the treatment chronic LBP. Future high quality RCT will have to clarify whether MTT is effective and would be superior to other forms of therapeutic exercise.

Serum levels of tumour necrosis factor-alpha and interleukin-6 and their correlation with body mass index, weight loss, appetite and survival rate--preliminary data of Viennese outpatients with metastatic cancer during palliative chemotherapy.

The serum cytokine levels (in particular interleukine-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha)) of 61 advanced stage cancer patients receiving palliative chemotherapy as outpatients were determined with quantikine immunoassays. The values were correlated with body mass index (BMI), weight loss and appetite. Furthermore cytokine levels of patients who have died within one year were compared with those of patients who have survived more than a year. Serum levels of IL-6 (median: 1.93 pg/ml, range: 0.32-42.87) and of TNF-alpha (median: 2.55 pg/ml, range: 1.03-34.06) did not correlate with BMI, weight loss and appetite. Serum IL-6 levels of patients with survival time less than one year were significantly higher than the levels of patients who survived more than one year, no significant differences in TNF-alpha serum levels were evident. The data of this observation are consistent with current literature. Due to changes in serum levels of proinflammatory cytokines in response to chemotherapy and additional therapy, it is unlikely that IL-6 and TNF-alpha can be used as independent indicators for weight loss and appetite. Nevertheless, high serum levels of IL-6 correlate with short-time mortality.

Driving in Parkinson's disease - a health hazard?

BACKGROUND: The driving safety of Parkinson's disease (PD) patients has lately been questioned after several authors reported road accidents caused by sleep attacks in PD patients on dopaminergic medication. OBJECTIVES: To determine 1) whether PD patients in general and those on dopaminergic medication in particular are especially prone to cause severe road accidents and 2) whether there are PD symptoms or dopaminergic side effects with the potential to compromise driving safety. DATA SOURCE: Relevant articles were identified by electronic search of biomedical databases (1966-2002: MEDLINE, EMBASE, PASCAL, PUBMED), the Cochrane Controlled Trials Register, and reference lists of located articles. RESULTS: Despite frequent occurrence of potentially hazardous dopaminergic side effects (2-57 %) and disabling parkinsonian non-motor and motor disabilities (16-63 %), the two existing studies on accident rates suggest that PD patients are not more prone to cause road accidents than the rest of the population. Five further reports including 1346 patients and focusing on dopaminergically induced sleep attacks provided comparably low accident figures (yearly incidence: 0%-2%). Because of low figures meta-analysis was intended but finally deemed inappropriate as the methodology of included studies varied greatly and was frequently flawed. CONCLUSION: Further prospective community-based well designed studies on accident risk in PD patients are needed to provide evidence based driving recommendations.

Implementation of the Vienna Hydrotherapy Group for Laryngectomees--a pilot study.

GOALS: Laryngectomy involves several problems for the individual, such as the need to cope with a stoma, adjustment to tracheostomal breathing, and the formation of a voice. Contact with water, resulting in aspiration, may prove fatal for laryngectomized patients in the absence of appropriate aids. The aim of this pilot study was to conduct a hydrotherapy group for laryngectomized patients and to evaluate its feasibility and outcome in relation to the goals of therapy. PATIENTS AND METHODS: Six male patients who had undergone laryngectomy were included in a pilot study. The patients underwent a structured hydrotherapy rehabilitation program (three times a week for 8 weeks), using a special underwater therapy device. The patients' posture was controlled by posturography and their endurance capacity by standard ergometry and the 6-min walk. The parameters of fatigue, expectoration, mobility, elasticity/flexibility, postural control/coordination, and general well being were registered on a visual analog scale (VAS). Quality of life was assessed by having the patients fill out the German version of the SF-36 Health Survey. MAIN RESULTS: Posturograpy findings showed an improvement of two subtests ( p<0.028). Exercise testing showed an improved endurance capacity ( p<0.028). The patients were able to walk a greater distance in the 6-min walking test ( p<0.028). The VAS also showed an improvement of endurance capacity ( p<0.028), fatigue ( p<0.028), expectoration ( p<0.043), mobility of the neck and shoulder ( p<0.027), flexibility ( p<0.027), postural control and coordination ( p<0.028), and general well being ( p<0.028). On the SF-36 Health Survey, the patients were improved in the items "Physical functioning" ( p<0.027), "Vitality" ( p<0.027) "Role-physical" ( p<0.026), and "Social functioning" ( p<0.043). CONCLUSIONS: A hydrotherapy group for laryngectomized patients proved to be safe, feasible, and effective in this pilot study.

East-west differences in the organization of botulinum toxin use in nine Central European countries.

Availability and quality of expensive treatment modalities such as botulinum toxin (BTX) largely depend on organizational aspects such as costs, reimbursement by insurance companies, expertise and facilities for expert training, and the propagation of research. To investigate which determinants influence the organization of BTX' use throughout nine Central European countries (Austria, Croatia, Czech Republic, Germany, Hungary, Italy, Slovakia, Slovenia and Switzerland) we sent out questionnaires to leading BTX experts and consulted data banks of manufacturers and bulletins of international organizations. In Western European countries, there is a tendency for users to organize themselves in formal groups and to concentrate on research whereas the way how BTX is provided is diverse regarding qualifications of specialists and institutions. In the post-communist Eastern European countries, we found a tendency towards a centralized system of reimbursement and BTX treatment seems to be more in the hands of neurologists than any other specialists. Strong correlations were observed between the number of BTX centres, degree of organization of user groups and number of scientific publications, on the one hand, and parameters of healthcare performance and socioeconomic determinants, on the other. Our study suggests that in the nine countries surveyed, organizational aspects of BTX use vary considerably, whilst similarities are based mainly on socioeconomic rather than socio-demographic determinants.

Aerobic exercise for a patient suffering from metastatic bone disease.

A 48-year-old female patient suffering from advanced breast cancer with metastatic bone disease participated in an aerobic exercise program consisting of ergometer cycling three times a week for 1 year. Feasibility, safety and beneficial effects of the program were proven for the patient in this case study. VO(2)max (20.2% after 16 weeks, 52.7% after 12 months) and peak work capacity (15.5% after 16 weeks, 35.7% after 12 months) had increased. The patient experienced a marked improvement in physical performance and in quality of life. Aerobic exercise, initiated and executed with appropriate care, may serve as a useful additional means of palliative treatment in some cancer patients with bone metastases.

[Postoperative rehabilitation of patients with carpal tunnel syndrome]. / Postoperative Rehabilitation von Patienten mit Karpaltunnelsyndrom.

The purpose of this study was to investigate the effect of mobilisation or splinting on symptoms after surgical Treatment of Carpal Tunnel Syndrome. Only original articles concerning the effect of mobilisation or splinting on symptoms after surgical Treatment of Carpal Tunnel Syndrome were included in this investigation. Concerning these topics only seven original articles were found. There was no significant influence of splinting for several weeks found on the symptom "pain" in the literature. Even there was a delay of returning to activities of daily living and the recovery of fist und keypinch strength through splinting. A program of physiotherapy and ergotherapy lead to a significant shorter recovery of dexterity in comparison to an home exercise program. Even the rehabilitated patients showed a shorter return-to-work interval. After carpal tunnel surgery neither physiotherapy nor splinting lead to a significant release of the symptom "pain". But physiotherapy leads to a shorter recovery of dexterity and shorter return-to-work interval. Due to the lack of knowledge about this topic further controlled clinical studies investigating the rehabilitation process after carpal tunnel surgery would be necessary.

[Botulinum toxin--the dose controls the poison. A historical sketch]. / Botulinumtoxin--Die Dosis macht das Gift. Ein historischer Abriss.

Botulism, a potentially lethal form of paralytic food poisoning, was described as early as 1793. Basic research, especially in the late nineteenth and early twentieth centuries, revealed that botulism is caused by exotoxins. Further biochemical work around and after the Second World War gave insight into the molecular structure of seven different serotypes of botulinum toxin (BT/A-G) as well as into its acetylcholine blocking mode of action. In 1977, Scott treated patients with strabism by injecting minute amounts of purified BT/A. In short sequence, BT proved effective in blepharospasm, cervical dystonia, and various off-label indications. In the near future, registration of these new indications, marketing of new serotypes (BT/B), and availability of more practical antibody tests can be expected. The first applications of BT were performed by Roggenkaemper, Dressler, and Benecke in Germany and by Poewe and Auff in Austria. According to a worldwide trend, a rapid expansion regarding BT users and indications followed. Formation of BT competence centers in both countries aims at maintaining high standards in BT research and education.

[Aerobic physical training in a breast cancer patient with inflammatory recurrence]. / Aerobes Bewegungstraining bei einer Mammakarzinompatientin mit inflammatorischem Rezidiv.

Aerobic exercise has positive effects on physical performance and illness-related quality of life of cancer patients. However reports of advanced cancer patients who exercise are rare in medical literature. A 38-year-old female patient suffering from breast cancer performed an aerobic exercise program during adjuvant chemotherapy (cycle ergometry, 3x/w). After the diagnosis of relapsed inflammatory breast cancer, oncological treatment was changed to radiation therapy to reduce tumour mass. The patient continued the exercise program until palliative mastectomy. Her compliance was excellent. Despite the underlying progressive disease, endurance performance improved substantially. These findings were supported by a subjective score (Grimby). Evaluation of quality of life (SF-36, EORTC-QLQ-C30) revealed improvements of emotional wellbeing, emotional role, vitality and physical functioning, but increasing pain. The patient reported benefit due to increased psychological, social and physical wellbeing. This case report demonstrates feasibility and benefits of aerobic exercise for a patient with advanced breast cancer undergoing palliative treatment.

Pilot study with pegylated liposomal doxorubicin for advanced or unresectable hepatocellular carcinoma.

We performed a pilot-study on pegylated liposomal doxorubicin (PLD) for advanced hepatocellular carcinoma. Seventeen patients received 40 mg/m(2) PLD intravenously every 4 weeks. A clinical benefit response was achieved in 50% (complete remission 7%, minor remission 7%, stable disease 36%). Toxicities were moderate. In view of these encouraging findings, further studies appear warranted.

Health related quality of life in patients with long-standing insulin dependent (type 1) diabetes mellitus: benefits of regular physical training.

BACKGROUND AND AIMS: Regular exercise is recommended to diabetic patients in addition to dietary restrictions and drug therapy. We have studied whether health related quality of life (HRQOL) can be improved by a regular physical training program. METHODS: 23 otherwise healthy patients with history of type 1 diabetes for 20 +/- 10 years were included. 15 patients (age: 41 +/- 2 years) participated in an aerobic physical training program over 4 months and 8 patients (33 +/- 11 years) served as a control group. HRQOL was assessed by a validated questionnaire (MOS SF-36). Tests were carried out at baseline and after 4 months. RESULTS: Physical training increased peak oxygen uptake (VO2max) by 27 +/- 13% after 4 months (p = 0.04) in the training group. There was no significant change in hand or leg isometric muscle strength. All HRQOL scales improved in the training group with significantly higher (p < 0.04) Social Functioning and Vitality scores, respectively. Moreover, insulin requirements decreased during physical training program (p < 0.05). CONCLUSIONS: Our data indicate that physical exercise training in patients with type I diabetes mellitus improves metabolic control and various aspects of HRQOL. Besides enhanced cardiorespiratory capacity, this is an important subjective benefit in patients with longstanding insulin dependent (type 1) diabetes mellitus.

Neuromuscular electric stimulation in heart transplantation candidates with cardiac pacemakers.

Twenty percent of heart transplantation candidates have cardiac pacemakers. Application of neuromuscular electric stimulation (NMES) in patients with pacemakers is controversial because of potential electromagnetic field interference and subsequent failure of the pacemaker. We present a safety protocol as a procedure before applying NMES in pacemaker patients. In 4 patients with chronic heart failure, NMES was applied under supervised conditions for 20 minutes to evaluate the individual risk. No changes in the clinical state and no complications secondary to electromagnetic field interference were observed. A check of pacemaker function after this 20-minute stimulation revealed no changes in the pacemaker parameters. After a thorough safety protocol, NMES of knee extensor muscles in patients with pacemakers appears to be safe.
