Hormonothérapie dans le cancer du sein: efficacité et effets adverses [Endocrine therapy in breast cancer: efficacy and adverse events].

Endocrine therapy remains a mainstay in the treatment of endocrine-sensitive breast cancer. In the adjuvant setting, 5 years of endocrine therapy significantly reduces recurrence rate and mortality. Tamoxifen is the molecule of choice for premenopausal women, whereas for postmenopausal women aromatase inhibitors are currently part of the standard treatment. Endocrine therapy can induce side effects, which can affect patient's quality of life and lead to premature treatment interruption. Identification and adequately addressing these side effects is fundamental to maintain good treatment compliance and therefore improve breast cancer specific outcome.

The value of adding mirror therapy for upper limb motor recovery of subacute stroke patients: a randomized controlled trial.

BACKGROUND: Upper limb paresis remains a relevant challenge in stroke rehabilitation. AIM: To evaluate if adding mirror therapy (MT) to conventional therapy (CT) can improve motor recovery of the upper limb in subacute stroke patients. DESIGN: Prospective, single-center, single-blind, randomised, controlled trial. SETTING: Subacute stroke patients referred to a Physical and Rehabilitation Medicine Unit between October 2009 and August 2011. POPULATION: Twenty-six subacute stroke patients (time from stroke <4 weeks) with upper limb paresis (Motricity Index â0/00¤ 77). METHODS: Patients were randomly allocated to the MT (N.=13) or to the CT group (N.=13). Both followed a comprehensive rehabilitative treatment. In addition, MT Group had 30 minutes of MT while the CT group had 30 minutes of sham therapy. Action Research Arm Test (ARAT) was the primary outcome measures. Motricity Index (MI) and the Functional Independence Measure (FIM) were the secondary outcome measures. RESULTS: After one month of treatment patients of both groups showed statistically significant improvements in all the variables measured (P<0.05). Moreover patients of the MT group had greater improvements in the ARAT, MI and FIM values compared to CT group (P<0.01, Glass's Î" Effect Size: 1.18). No relevant adverse event was recorded during the study. CONCLUSION: MT is a promising and easy method to improve motor recovery of the upper limb in subacute stroke patients. CLINICAL REHABILITATION IMPACT: While MT use has been advocated for acute patients with no or negligible motor function, it can be usefully extended to patients who show partial motor recovery. The easiness of implementation, the low cost and the acceptability makes this therapy an useful tool in stroke rehabilitation.

Intermittent ketoconazole therapy of chronic mucocutaneous candidiasis in childhood.

We report the clinical and laboratory findings in two children with chronic mucocutaneous candidiasis (CMC) treated successfully with intermittent long-term ketoconazole therapy. Both had chronic infection of the nails, skin and mucous membranes with positive cultures for candida. Both were resistant to multiple local and systemic antifungal agents. After institution of ketoconazole therapy there was a dramatic improvement with clearing of the oral (one week), skin (two months) and nail lesions (5 months). After 8 months the drug was stopped and clinical remission persisted for 10 and 7 months respectively. Relapse of oral candidiasis was treated with a short course of ketoconazole (4-16 weeks) leading to complete healing of the lesions. Clinical improvement was not related to an amelioration in lymphocyte transformation. There was no change in the progressive deterioration of the lymphocyte responses to candida antigen which was probably due to persisting candida cell wall components (e.g. mannan).

Photodynamic therapy enhances lipodoxorubcin distribution in sarcoma lung metastasis by lowering tumor interstitial fluid pressure in a rodent model

Objective: The management of sarcoma metastasis by systemic chemotherapy is often unsatisfactory. This has paradoxally been attributed to the leakiness of tumor neovessels which induce high intratumor interstitial fluid pressure (IFP) and limit convection forces that are important for drug distribution. In a rodent model, we have recently shown that photodynamic (PDT) pre treatment of lung metastasis could enhance their uptake of chemotherapy. We hypothesized that PDT transiently decreases tumor IFP which enhances convection and promotes drug distribution.Methods: Sarcoma tumors were generated sub-pleurally in the lungs of 12 rats. Animals were randomized at 10 days into i. no pre-treatment (control) and ii. low dose PDT pre-treatment (0・0625 mg/kg Visudyne, 10J/cm2 and 35 mW/cm2) followed by intravenous Liposomal doxorubicin (LiporubicinTM) administration. Using the wick-in-needle technique, we determined tumor and normal tissue IFP before, during and after PDT. In parallel, the uptake of LiporubicinTM was determined by high performance liquid chromatography in tumor and lung tissues.Results: Tumor IFP was significantly higher than normal tissue IFP in all animals. PDT pre-treatment did not affect normal tissue IFP but caused a significant decrease in tumor IFP (mean decrease by 2+/− 1mmHg) which lasted an average of 30 minutes before reaching baseline values. Tumor but not normal lung tissue LiporubicinTM uptake was significantly increased by 67% with PDT pre-treatment when liporubicin was allowed to circulate for one hour.Conclusion: Photodynamic therapy pre-treatment enhances LiporubicinTM uptake in sarcoma lung metastasis by transiently decreasing tumor IFP. These PDT conditions seem to specifically modulate tumor neovessels but not normal lung vessels.
