Deferasirox reduces iron overload significantly in nontransfusion-dependent thalassemia: 1-year results from a prospective, randomized, double-blind, placebo-controlled study

Nontransfusion-dependent thalassemia (NTDT) patients may develop iron overload and its associated complications despite receiving only occasional or no transfusions. The present 1-year, randomized, double-blind, placebo-controlled THALASSA (Assessment of Exjade in Nontransfusion-Dependent Thalassemia) trial assessed the efficacy and safety of deferasirox in iron-overloaded NTDT patients. A total of 166 patients were randomized in a 2:1:2:1 ratio to starting doses of 5 or 10 mg/kg/d of deferasirox or placebo. The means ± SD of the actual deferasirox doses received over the duration of the study in the 5 and 10 mg/kg/d starting dose cohorts were 5.7 ± 1.4 and 11.5 ± 2.9 mg/kg/d, respectively. At 1 year, the liver iron concentration (LIC) decreased significantly compared with placebo (least-squares mean [LSM] ± SEM, -2.33 ± 0.7 mg Fe/g dry weight [dw], P = .001, and -4.18 ± 0.69 mg Fe/g dw, P < .001) for the 5 and 10 mg/kg/d deferasirox groups, respectively (baseline values [means ± SD], 13.11 ± 7.29 and 14.56 ± 7.92 mg Fe/g dw, respectively). Similarly, serum ferritin decreased significantly compared with placebo by LSM -235 and -337 ng/mL for the deferasirox 5 and 10 mg/kg/d groups, respectively (P < .001). In the placebo patients, LIC and serum ferritin increased from baseline by 0.38 mg Fe/g dw and 115 ng/mL (LSM), respectively. The most common drug-related adverse events were nausea (n = 11; 6.6%), rash (n = 8; 4.8%), and diarrhea (n = 6; 3.6%). This is the first randomized study showing that iron chelation with deferasirox significantly reduces iron overload in NTDT patients with a frequency of overall adverse events similar to placebo.     

Effect of heterotopic noxious conditioning stimulation on electrical and pressure pain thresholds in two different anatomical regions

Objectives. The aims of the study were to investigate the influence of heterotopic noxious conditioning stimulation (HNCS) on pain thresholds in the orofacial and spinal regions and to find out whether there are gender differences in this respect. Material and Methods. Thirty healthy subjects (15 of each sex) with a mean (SD) age of 25.1 (4.4) years participated. Pain thresholds to electrical (EPT) and pressure stimuli (PPT) were recorded in the masseter muscle and 1st upper incisor (tooth), as well as in the fingertip, before, during, and 5 and 15 min after a cold pressor task to the contralateral hand immersed in ice-cold water for a maximum of 5 min. Results. With the exception of the EPT in the orofacial region, all pain thresholds increased during the HNCS and then returned to baseline during the 15 min follow-up. The significant changes in EPT were greater in the finger than in the tooth, while the changes in PPT were greater in the masseter muscle than in the finger. Electrical stimuli in the finger induced greater significant changes of pain thresholds than pressure. In the orofacial region, pressure induced greater significant changes in pain thresholds during HNCS than electrical stimuli did. The HNCS induced pain of high intensity and unpleasantness, i.e. varying between 5 and 10 on the numeric rating scale (NRS). There were no gender differences in the response to the HNCS. Conclusion. We conclude that, in general, HNCS induced by cold pressor stimulation increases pain thresholds, but the magnitude of the effect differs between the orofacial region and the finger and is influenced by the tissue and type of test stimuli.     

Training with a mirror in rehabilitation of the hand

Treatment with a mirror gives an illusion of function in a missing or non-functioning hand. The method is based on the concept that the central representation of phantoms and body image can change rapidly, and has been described in the treatment of phantom pain and stroke. We show in three pilot cases new applications for the use of the mirror in rehabilitation after hand surgery.     

Standardization of definitions in focal therapy of prostate cancer: report from a Delphi consensus project

Purpose

To reach standardized terminology in focal therapy (FT) for prostate cancer (PCa).

Methods

A four-stage modified Delphi consensus project was undertaken among a panel of international experts in the field of FT for PCa. Data on terminology in FT was collected from the panel by three rounds of online questionnaires. During a face-to-face meeting on June 21, 2015, attended by 38 experts, all data from the online rounds were reviewed and recommendations for definitions were formulated.

Results

Consensus was attained on 23 of 27 topics; Targeted FT was defined as a lesion-based treatment strategy, treating all identified significant cancer foci; FT was generically defined as an anatomy-based (zonal) treatment strategy. Treatment failure due to the ablative energy inadequately destroying treated tissue is defined as ablation failure. In targeting failure the energy is not adequately applied to the tumor spatially and selection failure occurs when a patient was wrongfully selected for FT. No definition of biochemical recurrence can be recommended based on the current data. Important definitions for outcome measures are potency (minimum IIEF-5 score of 21), incontinence (new need for pads or leakage) and deterioration in urinary function (increase in IPSS >5 points). No agreement on the best quality of life tool was established, but UCLA-EPIC and EORTC-QLQ-30 were most commonly supported by the experts. A complete overview of statements is presented in the text.

Conclusion

Focal therapy is an emerging field of PCa therapeutics. Standardization of definitions helps to create comparable research results and facilitate clear communication in clinical practice.

     

The management of stroke in Phnom Penh, Cambodia

Stroke ranks first among nervous pathologies in Kampuchea. It's a main cause of disability and mortality in our country. We conducted a prospective study including 100 patients hospitalized in the service of general medicine at the Calmette hospital in Phnom Penh. We analyzed the principal risk factors, clinical signs, nature of stroke, complications and markers of the vital and functional prognosis. This work shows the difficulties encountered in the initial care of stroke: delay or absence of hospitalization, cost of complementary examinations to be carried out to determine the nature and the aetiology of stroke and very low level of follow-up to ensure secondary prevention and functional rehabilitation. It can be explained in part by the socioeconomic and cultural level. Research like this one which assesses local needs for stroke prevention, treatment and rehabilitation should be conducted in developing countries to inform the planning and allocation of health care resources in order to reduce the burden of illness associated with stroke. The progressive improvement of the medical structures, and of the socioeconomic and cultural level will facilitate stroke care management.

Evaluation of phenoxymethylpenicillin treatment of acute otitis media in children aged 2-16

OBJECTIVE: To study the clinical recovery from acute otitis media (AOM) in children, 2-16 years of age, managed with or without treatment with phenoxymethylpenicillin (PcV). DESIGN: An open, prospective randomized trial. Children aged between 2 and 16 years, presenting with one- or double-sided AOM (without perforation) with symptom duration of less than four days, were included. The children were randomized to PcV for five days or to no primary antibiotic treatment. A health score and compliance were registered on a daily basis for seven days. SETTING: A total of 32 health centres and 72 GPs in south-east Sweden. Subjects. Children aged 2-16 presenting with earache. MAIN OUTCOME MEASURES: Recovery time, symptom duration, frequency of complications (up to three months) and consumption of healthcare services independent of treatment with or without antibiotics. RESULTS: A total of 179 patients carried out the trial; 92 were randomized to PcV, 87 to no primary antibiotic treatment. The median recovery time was four days in both groups. Patients who received PcV had less pain (p <0.001) and used fewer analgesics. There were no significant differences in the number of middle-ear effusions or perforations at the final control after three months. Children randomized to PcV treatment consulted less (p <0.001) during the first seven days. CONCLUSIONS: Our investigation supports that PcV treatment of AOM does not affect the recovery time or complication rates. PcV provided some symptomatic benefit in the treatment of AOM in otherwise healthy children, aged 2-16 years.
