Psychological approaches during dressing changes of burned patients: a prospective randomised study comparing hypnosis against stress reducing strategy

A prospective study was designed to compare two psychological support interventions in controlling peri-dressing change pain and anxiety in severely burned patients. Thirty patients with a total burned surface area of 10–25%, requiring a hospital stay of at least 14 days, were randomised to receive either hypnosis or stress reducing strategies (SRS) adjunctively to routine intramuscular pre-dressing change analgesia and anxiolytic drugs. Visual analogue scale (VAS) scores for anxiety, pain, pain control and satisfaction were recorded at 2-day intervals throughout the 14-day study period, before, during and after dressing changes. The psychological assistance was given on days 8 and 10 after hospital admission. The comparison of the two treatment groups indicated that VAS anxiety scores were significantly decreased before and during dressing changes when the hypnotic technique was used instead of SRS. No difference was observed for pain, pain control and satisfaction, although VAS scores were always better in the hypnosis group. The study also showed that, overall, psychological support interventions reduced pain and increased patient satisfaction. These results confirm the potential benefits of psychological assistance during dressing changes in burned patients.     

Slow dynamic lymphoscintigraphy is not a reliable predictor of sentinel-node negativity in cutaneous melanoma

We reviewed data from 160 consecutive patients (89 M/71 F; 53.5 [range, 9-88] years) who had under-gone lymphoscintigraphy and sentinel lymph node biopsy (SNB) in our hospital for histologically proven cutaneous malignant melanoma (CMM) (located on the upper limb: 33; lower limb: 57; trunk: 44; and head and neck: 26 patients), with a Breslow index > 1 mm and without clinical or radiologic evidence of metastatic spread. Colloidal (99m)Tc-rhenium sulfide (36-76 MBq) was injected intradermally in the four quadrants around the tumorectomy scar, followed by dynamic acquisition and static imaging. SN(s) were identified in 157 patients (overall identification rate, 98%). Fast (< 20 minutes), intermediate (20-30 minutes), or slow (> 30 minutes) lymphatic drainage was observed, respectively, in 122 (78%), 24 (15%), or 11 (7%) cases. Overall malignancy rate was 15%, respectively found in 19 (16%), 2 (8%), and 2 (18 %) patients with fast, intermediate, or slow drainage. No statistical difference between SN-positivity rates of patients with fast (19/122 = 16%) versus intermediate or slow drainage (4/35 = 11.4%) was observed (p = 0.69). Therefore, lymphoscintigraphic SN appearance time in CMM patients is unable both to predict SN metastasis and spare them from undergoing SN excision.     

Open Transcatheter Mitral Valve Implantation Into the Native Mitral Valve for Inoperable “Big MAC”

Because of the growing population of older adult patients, the prevalence of severe mitral annulus calcification (“big MAC”) is increasing. The surgical techniques used to treat big MACs are technically demanding; despite the technical aspect, up to one-third of patients are considered too high risk for conventional surgery but are candidates for the coulisse technique, which is a procedure that implants a transcatheter valve into a native mitral annulus. The anterior leaflet is unfolded, thus reducing the risk of obstructing the left ventricular outflow tract and for paravalvular leak and avoiding valve migration. Preoperative planning, based on a computed tomography scan, is mandatory.     

Resolutive Candida utilis fungemia in a nonneutropenic patient.

We report here the second case of Candida utilis infection in humans. The patient was apparently immunocompetent, had no central catheter, and survived an 8-day fungemia. Genomic analysis confirmed the conspecificity of medical and industrial strains of C. utilis and that of the anamorphic yeast C. utilis with the teleomorphic yeast Pichia jadinii.     

Low Levels of Omega-3 Long-Chain Polyunsaturated Fatty Acids Are Associated with Bone Metastasis Formation in Premenopausal Women with Breast Cancer: A Retrospective Study

In the present study, we investigated various biochemical, clinical, and histological factors associated with bone metastases in a large cohort of pre- and postmenopausal women with breast cancer. Two hundred and sixty-one consecutive women with breast cancer were included in this study. Breast adipose tissue specimens were collected during surgery. After having established the fatty acid profile of breast adipose tissue by gas chromatography, we determined whether there were differences associated with the occurrence of bone metastases in these patients. Regarding the clinical and histological criteria, a majority of the patients with bone metastases (around 70%) had tumors with a luminal phenotype and 59% of them showed axillary lymph node involvement. Moreover, we found a negative association between the levels of n-3 long-chain polyunsaturated fatty acids (LC-PUFA) in breast adipose tissue and the development of bone metastases in premenopausal women. No significant association was observed in postmenopausal women. In addition to a luminal phenotype and axillary lymph node involvement, low levels of n-3 LC-PUFA in breast adipose tissue may constitute a risk factor that contributes to breast cancer bone metastases formation in premenopausal women.     

Case of femoral pseudarthrosis due to Scedosporium apiospermum in an immunocompetent patient with successful conservative treatment and review of literature

Scedosporium apiospermum is a ubiquitous filamentous fungus, commonly found in soil, sewage and polluted waters. It is rarely pathogenic but can cause a broad spectrum of clinical diseases, which can be localised or disseminate to distant organs. The disseminated form of the disease is mostly seen among immunocompromised patients. However, some rare cases of disseminated disease have been reported in immunocompetent individuals. Treatment of these infections is challenging because of their natural resistance to many antifungal agents. Here, we report the case of a 57‐year‐old immunocompetent patient diagnosed with femoral pseudarthrosis due to S. apiospermum, despite having no obvious clinical sign of infection. Previously, the patient had undergone four iterative femoral surgeries following a road traffic accident which occurred 20 years before. During its last surgery for pseudarthrosis, no clinical or biological signs of infection were present. Per operative samples tested positive for S. apiospermum. The patient was successfully treated with oral voriconazole during 6 months with an excellent tolerance. We also provide a review of literature on bone and joint infections due to Scedosporium spp. (S. apiospermum, Scedosporium boydii and Scedosporium aurantiacum), discussing the evolution of their management and outcome which seems to improve since the use of voriconazole.     

Plasma exchanges overcome persistent iodine overload to enable 131I ablation of differentiated thyroid carcinoma.

BACKGROUND: Amiodarone has a high iodine content that can induce persistent iodine excess and may prevent radioiodine (RI) treatment. PATIENT: A 55-year-old obese man had taken amiodarone (200 mg/d) for 3 years and stopped 2 years earlier. He underwent total thyroidectomy for papillary cancer with extrathyroidal extension and a metastatic central lymph node, requiring RI treatment. But iodine overload, with no other documented iodinated drug intake, was found (urinary iodine excretion = 472 microg/24 h; normal < 150 microg/24 h), and persisted 3 months later. Plasma exchanges (PE) were prescribed. INTERVENTIONS AND RESULTS: Eight PE over 4 weeks were needed to eliminate 39,295 nmol of iodine. Urinary iodine excretion and serum iodine concentrations, before PE and after eight sessions were, respectively: 230 and 84 nmol/mmol of creatinine, and 811 and 71 nmol/L, enabling RI treatment (4 GBq (131)I). Post-therapy whole-body scan revealed cervical uptake (0.48% of the total administered dose) corresponding to usual thyroid remnants. Ablation efficacy was confirmed 6 and 24 months later by cervical ultrasonography combined with an undetectable serum thyroglobulin level after recombinant human thyrotropin stimulation. CONCLUSIONS: When spontaneous iodine elimination is too slow to allow RI treatment of high-risk thyroid carcinoma within a reasonable time after thyroidectomy, PE are reliable and effective to overcome iodine overload.     

A HYPNOSIS-BASED GROUP INTERVENTION TO IMPROVE QUALITY OF LIFE IN CHILDREN WITH CANCER AND THEIR PARENTS

Many children with cancer and their parents suffer from distress, fatigue, and relational difficulties. Hypnosis is often used to decrease children’s procedure-related pain and distress in pediatric oncology and to improve the well-being of adults with cancer. This article describes a pilot study assessing the acceptability and feasibility of a group intervention combining self-care and hypnosis for children with cancer and their parents, and a quasi-experimental protocol aimed at assessing the efficacy of this intervention to improve quality of life, distress, fatigue, and coping. The pilot study showed that the intervention was feasible and perceived positively. Future research is needed to test the efficacy of group interventions combining self-care and hypnosis to improve quality of life for children with cancer and their families.     

Interferon-induced differentiation of U937 cells. Comparison with other agents that promote differentiation of human myeloid or monocytelike cell lines.

Effects of human fibroblast (beta) or leukocyte (alpha) interferon (IFN) on differentiations of a human histiocytic lymphoma-derived cell line (U937) or promyelocytic leukemia-derived cell line (HL-60) were studied. When cultured with beta-IFN (400-1,000 U/ml), U937 cells showed gross morphologic and microscopic changes consisting of clumping, increased cytoplasmic-to-nuclear ratio, enhanced prominence of cytoplasmic granules, and membrane ruffling. After culture with beta-IFN, the number of U937 cells reactive with B43.4.1 monoclonal antibody, which is specific for human monocytes, natural killer cells, and neutrophils, increased from less than 10% of U937 cells to 47% beta-IFN treatment also enhanced antibody-dependent cellular cytotoxicity against chicken erythrocytes by U937 cells. The same morphologic, phenotypic, and functional changes were also observed when U937 were treated with recombinant or natural alpha-IFN. The effects of alpha-IFN were totally abolished by anti-alpha-IFN serum. In contrast, HL-60, which differentiates toward cells of the monocyte lineage in response to phorbol 12-myristate 13-acetate (based on the above criteria), and toward granulocytes in response to dimethyl sulfoxide, did not differentiate when cultured with alpha- or beta-IFN. No consistent relationship between induction of differentiation and changes in phospholipid methylation were observed.
