Interleukin-10 haplotypes in Celiac Disease in the Spanish population

Background  

Celiac disease (CD) is a chronic disorder characterized by a pathological inflammatory response after exposure to gluten in genetically susceptible individuals. The HLA complex accounts for less than half of the genetic component of the disease, and additional genes must be implicated. Interleukin-10 (IL-10) is an important regulator of mucosal immunity, and several reports have described alterations of IL-10 levels in celiac patients. The IL-10 gene is located on chromosome 1, and its promoter carries several single nucleotide polymorphisms (SNPs) and microsatellites which have been associated to production levels. Our aim was to study the role of those polymorphisms in susceptibility to CD in our population.     

Synergistic antitumor effect of melatonin with several chemotherapeutic drugs on human Ewing sarcoma cancer cells: potentiation of the extrinsic apoptotic pathway

Abstract:  Ewing sarcoma, the second most frequent bone cancer type, affects mainly adolescents, who have a survival of 50% 5 yr after diagnosis. Current treatments include a combination of surgery, radiotherapy and chemotherapy, which present potential serious side effects. Melatonin, a natural molecule without relevant side effects, has been previously shown to induce cytotoxicity in SK-N-MC cells, a Ewing sarcoma cell line. Here, we found that there is a synergy in the antitumor effect when melatonin (50 μ m –1 m m ) is combined with vincristine at the concentration of 5–10 n m or with ifosfamide at the range of 100 μ m –1 m m . This synergism is due to the potentiation of cell death, particularly to the potentiation of apoptosis, i.e., mainly the extrinsic apoptotic pathway. There is a significant increase in the activation of caspase-3, -8, -9 and Bid when melatonin is combined with vincristine or ifosfamide compared to the individual treatments. Finally, there is also a potentiation of the early free radical production, likely dependent on the extrinsic apoptosis pathway activation, when the drugs are combined with melatonin. Other proteins which are related to this pathway including mitogen-activated protein kinase or protein kinase B/Akt are not involved in apoptosis induced by these agents separately or when combined. The results shown here together with the facts that: (i) no relevant side effects have been reported for melatonin and (ii) melatonin has a cytoprotective effect on noncancer cells, opens the door for a new approach in the treatment of the Ewing sarcoma family of tumors.     

Effectiveness of the 23-valent polysaccharide pneumococcal vaccine against invasive pneumococcal disease in people 60 years or older

Background  

The 23-valent polysaccharide pneumococcal vaccine (PPV) is currently recommended in elderly and high-risk adults. However, its efficacy in preventing pneumococcal infections remains controversial. This study assessed the clinical effectiveness of vaccination against invasive pneumococcal disease (IPD) among people over 60 years.     

HELLP syndrome with severe liver dysfunction: a presentation of three cases

HELLP syndrome (HS) occurs in 0.5-0.9% of pregnant women. According to the Tennessee criteria, it is characterised by haemolytic anaemia, thrombopenia and multi-organ dysfunction. The purpose of this article is to present the cases of four pregnant women diagnosed with HS with severe liver involvement. PATIENTS AND METHOD: We present the cases of 4 pregnant women of 24, 27, 28 and 36 weeks gestation, respectively. Pregnancy was terminated by urgent Caesarean section in all 4 cases. The first case required a right hepatectomy, with a good post-operative outcome; the second patient developed fulminant liver failure, dying due to multi-organ failure while waiting for a liver transplant. The third patient progressed satisfactorily with conservative medical treatment. The fourth patient required two livers transplants, being discharged from hospital three months later. CONCLUSIONS: When faced with the clinical suspicion of a HS it is essential to rule out a liver haematoma, since the treatment of choice depends on its clinical-radiological severity. If there is a rupture of the haematoma, urgent surgery is essential and, in the case of severe liver failure, a liver transplant is indicated.     

Risk of Headache,Temporomandibular Dysfunction,and Local Sensitization in Male Professional Boxers: A Case-Control Study

Objective

To evaluate differences in the incidence of headache, trigeminal nerve mechanosensitivity, and temporomandibular functionality in professional male boxers (exposed to repetitive craniofacial trauma) who were actively training and without severe previous injuries compared with handball players.

Design

Case-control study.

Setting

University-based physical therapy research clinic.

Participants

Eighteen boxers (mean age, 23±4.61y) as the cases group, and 20 handball players as the comparison group (mean age, ±2y, and sex matched), were included. All participants (N=38) completed the assessment protocol.

Interventions

Not applicable.

Main Outcome Measures

Measurements were taken of the headache impact (Headache Impact Test-6) and the pressure pain threshold over the trigeminal nerve sensory branches, the masseter muscle, and the tibialis anterior muscle. The secondary outcome measure included the temporomandibular function (Helkimo Clinic Index).

Results

The boxers showed slight mandibular function impairment, local muscular and neural sensitization, and a higher impact from headaches than did the handball players. The between-group comparison found significant differences in all outcome measures (P<.05), except in the tibialis anterior muscle pressure pain threshold on the dominant (P=.958) and the nondominant (P=.453) sides.

Conclusions

Professional male boxers seem to suffer a greater headache impact and local sensitization of the craniomandibular region than do professional handball players. It cannot be determined whether these findings are short-lasting, as a result of the training activity, or long-lasting.     

Cirugía mayor ambulatoria del cáncer de mama: factores relacionados con la conversión a hospitalización convencional

Introduction

The main step in curative treatment for breast cancer is surgery. Its use in an ambulatory setting can contribute towards more efficient healthcare, providing additional benefits for patients. In this study, we analyze the results obtained with this treatment method and identify factors related with conversion to hospitalization.
