Persons with poststroke hemiparesis are characterized by asymmetry in limb loading (LL) and limb unloading (LU), which has been reported in static and quasi-static tasks but has not been quantified during walking. The purpose of this study was to determine the asymmetry in magnitude and duration of LL and LU in individuals with hemiparesis and its relationship with functional walking status and specific kinematic and kinetic variables during walking. Forty-four participants with chronic hemiparesis walked at their self-selected speeds and eighteen nondisabled control subjects of similar ages walked at predetermined matched speeds while three-dimensional ground reaction forces and body-segment kinematics were recorded. Magnitude of paretic LL was reduced, while duration was increased compared with the nonparetic leg and nondisabled controls walking at matched speeds. The paretic LL and LU was significantly correlated with average leg angle, while the nonparetic leg significantly correlated with average knee angle. Three different patterns of LL and LU were identified (concave, convex, and linear). Individuals with hemiparesis make several biomechanical adjustments that minimize LL of the paretic leg. LL deviations were more pronounced with increased lateral placement of the paretic foot and with decreased functional gait speed. Characterization of these deviations may inspire new strategies for rehabilitation.

Fatigue is one of the most common and most distressing problems in lymphoma patients. A vicious circle is presumed between fatigue, physical activity and physical fitness. It is plausible that an exercise training program would be effective in reducing fatigue, by breaking this vicious circle. The purposes of this review are to provide an overview of the literature on physical activity and physical fitness in lymphoma patients before, during and after anticancer treatment, and to summarise the literature on exercise training interventions in lymphoma patients. We conducted a search for studies reporting on physical activity, physical fitness or the effect of exercise training in lymphoma patients. A total of 13 articles were selected. Due to a small number of articles and methodological issues, it was not possible to make final conclusions. The results indicated that 21 % to 29 % of lymphoma survivors meet the American College of Sports Medicine public health guidelines for physical activity. Maximal exercise capacity was decreased before treatment, especially in patients with advanced disease, and was close to normal during and/or after treatment. Lower levels of physical activity as well as lower physical fitness seemed to be associated with more symptoms of fatigue. Aerobic exercise training interventions seemed to be feasible and safe and had positive effects on cardiorespiratory fitness, fatigue and self-reported physical functioning. Further research is needed to examine physical activity and physical fitness in a longitudinal, objective way in large samples and to examine the effect of exercise training in lymphoma patients.

The objective of this study is to evaluate the anatomical and functional results of rehabilitation of canal wall down (CWD) mastoidectomy using granules of biphasic ceramic. This is a study design retrospective in a tertiary referral centre Fifty-seven patients (59 ears) operated on between 2006 and 2010 of mastoid obliteration with granules of biphasic ceramic (TricOs(®), Maurepas, France) have been included (55 revisions and 4 first surgeries). Forty-six patients presented already a CWD mastoidectomy. The mean pre-operative bone conduction (BC) was 29 ± 3.4 dB (mean ± SEM) and mean air conduction (AC) was 57 ± 3.2 dB. Cholesteatoma was found in 33 cases. All but seven cases had post-operative otoscopy examination at 1, 3, 6 months, and 1 year postoperative with a CT scan and pure tone audiometry. Mean follow-up was 14 ± 1.8 months (3-35). At one-year follow-up (n = 52), 47 cases (90 %) presented well-healed external auditory canal. Five cases (10 %) of uncovered granules without sign of infection of external auditory canal skin were observed. Mean post-operative threshold was 25 ± 1.8 and 46 ± 1.9 dB for BC and AC , respectively (n = 47). CT scan (n = 42) showed no opacity suggesting residual disease within or behind obliteration. Mastoid obliteration with granules of biphasic ceramic is a safe and effective procedure that allows restoration of a near normal external auditory canal.

PURPOSE: The objective of the study is to investigate recent changes in patient characteristics and treatment procedures of young breast cancer patients over the last 10 years in Germany. METHODS: The study describes the data of 518 patients who were treated adjuvantly between 2008 and 2011 and participated in a resident mother-child program for rehabilitation (cohort II). The data includes TNM-categories, biology of tumor and therapies. This population is compared to a cohort of 535 patients, who were treated between 2002 and 2006 (cohort I). Characteristics and treatment of cohort II are compared with a normally age distributed cohort. RESULTS: 51.5 % of the patients in cohort II were diagnosed with tumor category pT1, 36.9 % pT2, 4.4 % pT3 and 1.2 % pT4. 3.3 % had merely DCIS. 58.1 % of the patients were pN0, 28.4 % pN1 and 13.5 % had a more intense manifestation of lymph nodes. 45.8 % of the tumors showed a grading classified as G3, 69.3 % were estrogen and progesterone hormone receptor positive and 21.8 % Her2 positive. 24.5 % of the examined patients showed a triple negative carcinoma. 66.2 % of the patients with pT1 or pT2 underwent breast-conserving surgery. Overall 19.2 % of the women received mastectomy only and 17.4 % received mastectomy with subsequent reconstruction. 98.6 % of the patients received axillary surgery, 87.6 % chemotherapy. Overall, 21.0 % of the patients received their chemotherapy in connection with clinical studies. 88.0 % of the patients with hormone receptor positive tumors received endocrine therapy, 25.5 % of them with GnRH-analogs. In comparison with cohort I the tumors in cohort II were detected with a higher proportion of negative lymph nodes (48.8 %/58.1 %, p = 0.008) and G1 grading (4.9/5.6 %, p = 0.001). On the other hand the percentage of triple negative tumors increased from 21.0 % to 24.5 % (p = 0.018). Operative therapy has adjusted to a more moderate way. Breast-conserving therapy with pT1 and pT2 increases from 57.3 % to 66.2 % (p = 0.006), sentinel lymph node biopsy only from 24.5 % to 47.5 % (p[Symbol: see text]0.001) over the years. The percentages of chemotherapy, radiation, endocrine therapy and antibody therapy with positive receptor have stayed stable over the last decade. Comparing cohort II with a normally age distributed group (DMP II 2007-2009) the young patients have still a much lower portion of negative lymph nodes (58.1 %/67.9 %) and positive hormone receptor status (69.3 %/85.1 %). The percentage of a high grading G3 is 45.8 % in cohort II versus 24.7 % in DMP II. The portion of breast-conserving therapy with pT1 is with 68.9 versus 82.2 % still comparatively low. Young patients received more axillary surgery (98.6 %/81.5 %) but less endocrine therapy with hormone receptor positive tumors (93.3 %/94.7 %). CONCLUSION: Young breast cancer patients in Germany can still be regarded as a special group. Although tumors are now more often detected before reaching the lymph nodes than 10 years ago, an even bigger percentage is triple negative. Operative treatment has improved to a less aggressive way. Still operative and medical treatments have to be chosen after very careful evaluation.
