Health-related quality-of-life assessment in gastrointestinal cancer: are results relevant for clinical practice?

PURPOSE OF REVIEW: Health-related quality-of-life studies are now recognized as critical to understand the burden of disease and treatments on patients' well being. Significant advances have been recently achieved in gastrointestinal cancers, including the development and clinical use of new robust quality-of-life instruments. We review recent literature to evaluate whether quality-of-life assessment contributes to optimal patient information and helps treatment choices. RECENT FINDINGS: Treatments of gastrointestinal cancers have changed in the last few years with increasing use of multimodal therapies and advances in surgical techniques, especially for low-lying rectal cancers. Concurrent to the development of sphincter-saving procedures, however, the long-term consequences of a permanent stoma on quality of life have been debated. Results of new palliative treatments should also be considered looking at preservation or improvement of quality of life and not only prolongation of life. SUMMARY: Gastrointestinal malignancies impact strongly on patient quality of life due to the aggressiveness of the treatments. Short-term negative effects of surgery and specific deficits in survivors were recently described in gastrointestinal cancers. Baseline quality-of-life data predict length of survival in hepatocarcinoma and metastatic colorectal cancer. Generally, quality-of-life results help to fully inform the patients of the advantages or disadvantages of therapeutic options, including adjuvant and palliative treatments.     

Immunosuppressive effects of mesenchymal stem cells: involvement of HLA-G

INTRODUCTION: Mesenchymal stem cells (MSCs) possess unique immunomodulatory properties. They are able to suppress allogenic T-cell response and modify maturation of antigen-presenting cells. Their role in the treatment of severe graft versus host disease has been reported. The underlying molecular mechanisms of immunosuppression are currently being investigated. Histocompatibility locus antigen (HLA)-G is a nonclassical major histocompatibility complex class I antigen with strong immune-inhibitory properties. METHODS: We studied the role of HLA-G on MSC-induced immunosuppression. The expression of HLA-G on human MSCs cultured alone and in mixed lymphocytes reaction (MSC/MLR) was analyzed. RESULTS: We found that HLA-G can be detected on MSCs by real-time reverse-phase polymerase chain reaction, immunofluorescence, flow cytometry (52.4+/-3.6%), and enzyme-linked immunosorbent assay in the supernatant (38.7+/-5.2 ng/mL). HLA-G protein expression is constitutive and the level is not modified upon stimulation by allogenic lymphocytes in MSC/MLR. The functional role of HLA-G protein expressed by MSCs was analyzed using the 87G anti-HLA-G blocking antibody in a MSC/MLR. We found that blocking HLA-G molecule significantly raised lymphocyte proliferation in MSC/MLR (35.5%, P=0.01). CONCLUSION: Our findings provide evidences supporting involvement of HLA-G in the immunosuppressive properties of MSCs. These results emphasize the potential application of MSCs as a relevant therapeutic candidate in transplantation.     

Multicenter assessment of ultrasound of the spermatic cord in children with acute scrotum

PURPOSE: Intravaginal or extravaginal spermatic cord torsion is a diagnostic challenge for the surgeon and radiologist. Color Doppler sonography can be inaccurate, leading to dangerous false-negative results. To date, no single reliable test has been able to provide 100% diagnostic accuracy. The direct visualization of the twisted cord during emergency high resolution ultrasonography has been proposed to avoid systematic and abusive surgical exploration. The aim of this multicenter study was to assess the validity and reproducibility of high resolution ultrasonography based management of acute scrotum in children. MATERIALS AND METHODS: A total of 919 patients from 11 European university hospitals underwent color Doppler sonography and high resolution ultrasonography for acute scrotum between 1992 and 2005. The spermatic cord was studied along its complete length to detect a spiral twist. The surgical findings were correlated with the preoperative results. RESULTS: A total of 208 patients had spermatic cord torsion proved at surgery. Intratesticular vascularization was absent in the affected testis in only 158 cases (76%). In contrast, high resolution ultrasonography detected the twist as a snail shell-shaped mass, measuring 7 to 33 mm, in 199 patients (96%). High resolution ultrasonography revealed a linear cord for all other causes of acute scrotum (711 patients) with a specificity of 99%. The radiologist training level was the best predictive factor of high resolution ultrasonography reliability (p <0.05). CONCLUSIONS: High resolution ultrasonography based management of acute scrotum is reliable and reproducible. Thanks to its high sensitivity and specificity for the diagnosis of spermatic cord torsion, high resolution ultrasonography can significantly improve the management of acute scrotum in children.     

Job of the Bible: leprosy or scabies?

Proposing a medical diagnosis a posteriori of a person who died a long time ago is not as impossible as it sounds if sufficient medical history is available.A whole book of the Bible is devoted to Job and his trials. The diagnosis of leprosy has been generally accepted by medieval commentators because the verses of the Book speak of ulcers disseminated over the skin, and also because leprosy is an exemplary sanction imposed by way of example by God to punish those who have committed a sin. In this paper, we have taken the different verses with a medical content from the Book of Job, and reconstructed the clinical picture as if the patient had turned up in the 21st century in order to see if the diagnosis of leprosy may be called into question, and to discuss the limits of the medico-historic approach. The clinical picture of the disease consists of deterioration in the general condition, with widespread pain, confusion, skin eruptions, bilious vomiting, and so on. Under these conditions, if Job did exist, and if the retrospective medical history is reliable, the most likely diagnosis is that of scabies rather than leprosy.     

Cardiac Surgery with Cardiopulmonary Bypass in Low-Weight or Preterm Neonates: A Retrospective Study Analyzing Early Outcome

Background: Most outcome studies in congenital cardiac surgery for “low weight” neonates include patients undergoing surgery without cardiopulmonary bypass (CPB). The primary objective of our study was to identify risk factors for in-hospital mortality in neonates weighing less than 3 Kg and undergoing surgery with CPB. In addition, we compared the effect of early surgery with CPB (before 37W-gestational age (GA)) for congenital heart disease to delayed surgery until a corrected GA of 37 weeks in an attempt to promote weight gain. Methods: Retrospective single-center study including all patients operated between 1997 and 2017. Uni- and multivariable analysis were used to analyze outcome. Results: 143 patients were included. The median weight was 2.7 Kg and 49 (34.3%) weighted <2.5 Kg. 80% of the patients were Risk stratification STAT categories ≥3. 114 patients (80%) were operated without delay (usual timing, median age 9 days), whereas 29 patients (20%) entered a delayed strategy (median age 30 days). In-hospital mortality was 21.7%. By multivariate analysis, dysmaturity, preoperative positive ventilation, post-operative ECMO requirement or resuscitation, and any residual lesion were predictors of in-hospital death. In-hospital mortality in the usual timing group and the delayed group were 21.1% and 24.1%, respectively (p = 0.71). In-hospital mortality for neonates operated prior to 37W-GA (n = 10) was 27.3%. Conclusions: Predictors of in-hospital mortality in neonates less 3 Kg requiring CPB surgery did not differ from those unveiled in other contemporary studies. Our data demonstrates that a strategy of delaying surgery in selected patients resulted in similar clinical outcome.     

Cutaneous CD8+ squamous T-cell bullous lymphoma

INTRODUCTION: Bullous forms of cutaneous T-cell lymphomas are rare. A new group of cutaneous T-cell lymphomas has recently been identified as a distinct clinicopathological and immunophenotype entity. These cutaneous T-cell lymphomas express a CD8+ phenotype, rarely expressed in other cutaneous T-cell lymphomas. CASE REPORT: We describe a cutaneous CD8+ squamous T-cell lymphoma with polymorphic clinical features, strongly epidermotropic lymphoid infiltrate and spongiosis, classical for this type of lymphoma. DISCUSSION: Bullous lesions in cutaneous T-cell lymphoma should evoke the possibility of a cutaneous CD8+ T-cell lymphoma, once other bullous diseases have been excluded. Spongiosis, rare in other types of T-cell lymphoma, and strongly epidermotropic pleomorphic lymphoid infiltrate are classical histological features. The association of polymorphic lesions, bullas and atypical CD8+ epidermotropic phenotype should evoke this diagnosis even at the early stage. Treatment is difficult and classical chemotherapy often fails. Prognosis is poor with a mean overall survival of 32 months.     

Pain in hereditary neuromuscular disorders and myasthenia gravis: a national survey of frequency, characteristics, and impact

The aim of our study was to evaluate pain frequency, intensity, and disability levels in a population with neuromuscular disorders (NMD). Of 862 questionnaires mailed to outpatients treated at 10 centers, 511 (300 men and 211 women) responded with answers suitable for analysis (response rate: 59.3%). Patients had Duchenne or Becker muscular dystrophy, type 1 myotonic muscular dystrophy, facioscapulohumeral muscular dystrophy, metabolic myopathy, or myasthenia gravis (MYA). The questionnaire packet included numeric scales for pain intensity and relief, the Brief Pain Inventory, the Saint Antoine Pain Questionnaire, and a scale to assess disability. More than two-thirds of the 331 patients (67.3%) suffered pain during the last three months. The mean number of days with pain was 18.4+/-15.1 days. The mean pain intensity was 4.8+/-2.5. Pain was usually diffuse (153 patients, 44%) and intermittent (228, 71%). Pain intensity varied by the NMD diagnosis; the most severe pain was observed in metabolic myopathy (13/27 patients suffered severe pain, 49%) and in MYA (16/42, 38%). Approximately three-quarters of patients had fewer than 10 days of inactivity due to pain during the last three months, and 98% had fewer than 30 days. Our study indicates that pain is frequent in hereditary muscle disorders and MYA. Mean intensity is moderate. Pain in NMD patients should be systematically assessed.
