Efecto de las técnicas de inducción miofascial en la reducción del dolor en pacientes con dolor miofascial pélvico crónico / Effect of myofascial induction techniques on pain reduction in patients with myofascial chronic pelvic pain

Introducción y objetivo El dolor miofascial pélvico crónico es una patología con una elevada prevalencia, y de etiología muy diversa, al igual que su tratamiento. No se ha establecido un protocolo de tratamiento, y hasta el momento, se recomienda un abordaje multidisciplinar. El objetivo es evaluar el efecto de un protocolo basado en 10 sesiones de técnicas de inducción miofascial (TIM) en pacientes con dolor miofascial pélvico crónico (DMPC). Material y métodos Se realizó un estudio cuasi experimental (antes-después), con una intervención basada en TIM adaptadas a la localización del dolor de los pacientes. Se evaluó la intensidad del dolor mediante la escala visual analógica (EVA) y la calidad de vida, tanto física como mental, mediante el cuestionario de salud SF-12v2. Para valorar el efecto de las TIM, se compararon los resultados preintervención-postintervención mediante la prueba t de Student para datos apareados y el test no paramétrico de Wilcoxon. Resultados Se incluyeron 50 pacientes en el estudio (27 mujeres y 23 hombres), con una edad media de 44,8 años (desviación estándar [DE] 12,1) y una duración media de los síntomas de 58,3 meses (DE 60,5). El análisis por protocolo mostró que la intensidad del dolor disminuyó en 3,99 puntos al final de la intervención y la calidad de vida mejoró en los sumatorios físico y mental en 5,45 y 5,87 puntos, respectivamente (p < 0,05). El 86,7% de los pacientes completó el protocolo de tratamiento. Conclusiones En un grupo de pacientes con dolor miofascial pélvico crónico, las TIM parecen tener un efecto beneficioso significativo, reduciendo el dolor y mejorando la calidad de vida (AU)

Introduction and objective Myofascial Chronic Pelvic Pain (MCPP) is a pathology with a high prevalence, and an aetiology as diverse is its treatment. A treatment protocol has not yet been established and a multidisciplinary approach is currently recommended. The aim is to evaluate the effect of a Myofascial Induction Techniques (MIT) protocol based on 10 sessions in patients with Myofascial Chronic Pelvic Pain. Material and methods A quasi-experimental study (before-after) was carried out, with an intervention based on MIT adapted to the location of the pain. Pain intensity was evaluated using the Visual Analogue Scale and quality of life, both physical and mental, was assessed using the SF-12v2 Health Survey questionnaire. To assess the effect of MIT, the pre-intervention and post-intervention results were compared using the Student's t test for paired data, and the non-parametric Wilcoxon test. Results 50 patients were included in the study (27 women and 23 men), with a mean age of 44.8 years (SD 12.1), and a mean duration of symptoms of 58.3 months (SD 60.5). The protocol analysis showed that pain intensity decreased by 3.99 points at the end of the intervention and quality of life improved in the physical and mental scores by 5.45 and 5.87 points, respectively (p < 0.05). Of the patients, 86.7% completed the treatment protocol. Conclusions In a group of patients with myofascial chronic pelvic pain, MIT appear to have a significant beneficial effect, reducing pain and improving quality of life (AU)

High consumption foods and their influence on energy and protein intake in institutionalized older adults.

BACKGROUND: The elderly, and especially those attending nursing homes, are at great risk from certain nutritional deficiencies. OBJECTIVE: The aim of this study was to determine which food groups present the highest rates of consumption among the institutionalized elderly and study the energy density of each food group and the number of calories and amount of protein in the total diet of each resident. DESIGN: This was a multicentre observational study of a sample of the institutionalized population over the age of 65. The sample of patients was drawn from four Spanish nursing homes (Santa Coloma Gramanet, Barcelona, Madrid and Bilbao). Our final sample comprised a total of 62 individuals, of whom 22 were men and 40 women, aged between 68 and 96 years. METHODS: Dietary data were collected using the double weight method for each main meal (breakfast, lunch, afternoon snack and dinner), including food type, the quantity of food served and the amount of plate waste for each of the main meals served during 21 days. STATISTICAL ANALYSES: The characteristics of the study population were compared by Student's t-test and χ2 test. The results are expressed in terms of their median values and the interquartile range. To analyse the overall differences between sites, gender and food groups we used Kruskall-Wallis test combined with the Mann-Whitney U-test with Bonferroni correction for multiple comparisons. RESULTS: The food group that was served most was milk products (376.25 g/day). A large amount of potatoes were also served (109.64 g/day) as were sweets and pastries (62.14 g/day). The daily serving of fruit (138.34 g/day) and vegetables (239.47 g/day) was equivalent to no more than that of a daily ration in each case. Milk was the food group with the highest consumption (311 g/day). Most of the energy was provided by groups with a higher energy density like as fats and sauces, sweets and pastries and bread. The mean protein consumption was 82,6 g/day (Table 5) and no significant differences were recorded in this consumption between men and women. CONCLUSIONS: We conclude that there is a need to improve the residents' energy intake and to redistribute their energy and protein intake among the various food groups. An alternative to increasing food portions so as to improve energy intake might involve enriching certain food types.

Renal expression of adhesion molecules in anca-associated disease.

INTRODUCTION: Anti-neutrophil cytoplasmic autoantibodies (ANCA)-associated disease among other manifestations can underlie rapidly progressive glomerulonephritis (RPGN), with crescentic and necrotizing GN. Differences in pathogenic immune mechanisms in RPGN may provide differences in the renal expression of adhesion molecules mediating these lesions. METHODS: Renal intercellular adhesion molecule 1 (ICAM-1; CD54) and vascular cell adhesion molecule 1 (VCAM-1; CD106) were assessed in 40 patients with type I RPGN (anti-glomerular basement membrane antibodies, n = 4), type II (immune complexes, n = 17), and type III (ANCA, n = 19). Enzyme-linked immunosorbent assay (ELISA) for detection of immunoglobulin G antibodies against the Goodpasture's antigen and indirect immunofluorescence and ELISA for myeloperoxidase (MPO) and proteinase 3 (PR3) were performed for ANCA testing. Ten normal renal tissues were used as controls. Relationships between ICAM-1 and VCAM-1, histopathologic features, and CD18, CD14, and CD3 cells were analyzed. RESULTS: Abnormal ICAM-1 and VCAM-1 in tubule was seen in >80% of biopsies with RPGN. Abnormal VCAM-1 in glomerular tuft was seen in >60% of biopsies with RPGN. Glomerular ICAM-1 was associated with less glomerulosclerosis (chi (2) = 6.719, p = 0.01), less interstitial fibrosis (chi (2) = 4.322, p < 0.05), and less tubular atrophy (chi (2) = 8.547, p < 0.005). Glomerular VCAM-1 was associated with glomerular leukocyte infiltration (chi (2) = 4.698, p < 0.05). Glomerular tuft stains of ++/+++ for VCAM-1 was observed in 10% from MPO-ANCA-GN patients but in 60% from PR3-ANCA-GN (Fi = 8.538, p = 0.03). CONCLUSIONS: The following conclusions can be made from this study. (1) The renal expression of ICAM-1 and VCAM-1 is upregulated in RPGN, and this is associated with the histological activity. (2) De novo expression of VCAM-1 on glomerular tuft suggests that endothelial cells play a role in RPGN. (3) De novo tubular expression of ICAM-1 and VCAM-1 suggests that epithelial cells may participate in adhesive interactions in RPGN. (4) De novo expression of VCAM-1 at the glomerular tuft in PR3-ANCA positive patients seems greater than in MPO-ANCA positive patients, which suggests that testing specific immune activation mechanisms may play a role in ANCA-associated GN.

Acoustic voice analysis in different phonetic contexts after larynx radiotherapy for T1 vocal cord carcinoma

INTRODUCTION: Radiotherapy for early vocal cord carcinoma affects quality of voice. Nevertheless, most patients refer to having a high satisfaction level with their voice. The few acoustic studies on quality of voice have been performed only in prolonged vowel production, which is not a usual speech situation. The present study has been done with the aim of establishing which phonetic situations reflect a greater alteration in voice production related to irradiation. MATERIAL AND METHODS: Eighteen male patients irradiated for Tis-T1 vocal cord carcinoma and a control group of 31 non-irradiated subjects were included in a study of acoustic voice analysis. This analysis was performed one year after radiotherapy. Patients and control group voices were tape recorded in extended vowel production, oral reading of a standard paragraph, spontaneous speech and in a song. Acoustic analysis was performed by a Kay Elemetric's Computerized Speech Lab (model CSL #4300). Fundamental frequency, jitter, shimmer and harmonics-to-noise ratio were obtained in both groups. Statistical test: Lin concordance coefficient and Pearson's correlation coefficient, Student's t-test and ROC curves. RESULTS: Concordance and correlation studies did not allow selection of any subgroup in acoustic parameters and different acoustic situations. Acoustic parameters had higher median values in irradiated patients. Student's t-test showed significant differences for fundamental frequency in sustained vowel production and spontaneous speech; for jitter there was statistical significance in all the acoustic situations and for shimmer in oral reading and song. Jitter showed a cut-off of 2.02% with a sensitivity of 89% and specificity of 97% in classifying irradiated and non-irradiated groups. The ROC curve for jitter correctly classified 94% of subjects into irradiated or non-irradiated groups. CONCLUSIONS: The present study showed that jitter obtained from spontaneous speech was the most relevant parameter in discriminating voice in irradiated patients by acoustic analysis. Jitter in spontaneous speech is in need of more analysis in bigger series and in more advanced stages of larynx cancer as its relevance has been demonstrated (AU)

Reduction in the prevalence and intensity of infection in Onchocerca volvulus microfilariae according to ethnicity and community after 8 years of ivermectin treatment on the island of Bioko, Equatorial Guinea.

Bioko is the only island known in the world with endemic onchocerciasis. The island's rural communities consist of villages and cocoa plantations inhabited by Bubi and Fang ethnic groups. The aim of this study was to evaluate the impact of 8 years of vertical ivermectin distribution on the prevalence and intensity of Onchocerca volvulus infection in the rural population by means of pre- (1989) and post-long term treatment (1998) epidemiological surveys. In both surveys, the entire population of 12 randomly selected communities (1723 and 1082 individuals) was examined. The mean ivermectin therapeutic coverage for the 8 years was 53.2%. Iliac crest skin snips were used for differential diagnosis between O. volvulus and Mansonella streptocerca. The crude O. volvulus infection prevalence before ivermectin intervention was 74.5% (1284/1723); after the intervention it was 38.4% (415/1082). The Community Microfilarial Load (CMFL) before and after ivermectin intervention was 28.29 microfilariae/snip vs. 2.32 microfilariae/snip. The reduction in prevalence and CMFL after eight annual rounds of ivermectin treatment corroborates the drug microfilaricidal activity and good tolerability. In the pre-treatment survey, the prevalence was higher in the Bubi group (77.1%, 1126/1461); post-treatment it was higher among the Fang (51.1%, 92/180). The reduction in prevalence and intensity of O. volvulus infection differed between ethnic groups and communities.

[Renal expression of intercellular adhesion molecule-1 (ICAM-1) in IgA deposit mesangial nephropathy. A tubulointerstitial lesion marker]. / Expresión renal de la molécula de adhesión intercelular-1 (ICAM-1) en la nefropatía mesangial por depósitos de IgA. Un marcador de lesión tubulointersticial.

BACKGROUND: The aim of this study was to determine the significance of the renal expression of ICAM-1 in IgA nephropathy (IgAN). PATIENTS AND METHOD: First, we identified ICAM-1 (CD54) expression in tubular epithelial cells and interstitial leucocytes in renal biopsies from 45 patients with IgAN and 29 patients with non-glomerulonephritis nephropathy (non-GN). We then analysed the relationship between this expression and both histological and clinical data at the time of renal biopsy and after 2.4 (2) (X [SD]) years in IgAN, and 1.8 (1.5) years in non-GN. RESULTS: In IgAN, tubular ICAM-1 positive staining was seen in 25 (55%) biopsies; it was associated with extracapillary proliferation, glomerulosclerosis involving less than 50% of glomerular area, interstitial cell infiltration and tubular atrophy. ICAM-1 positive interstitial leucocytes were 234 (307)/mm2; this expression correlated with glomerulosclerosis, tubular atrophy, interstitial fibrosis and serum creatinine (Cr) level. In patients with 50% increase in Cr level, ICAM-1 positive interstitial leucocytes were 516 (360)/mm2 as compared with 66 (87.8)/mm2 (U = 16; p < 0.005) in patients with stable Cr. In non-GN, tubular ICAM-1 expression was observed in 7 (24%) biopsies. CONCLUSIONS: Tubular and Interstitial expression of ICAM-1 can be a marker of tubulointerstitial damage in IgAN. Interstitial ICAM-1, rather than tubular ICAM-1, may predict the progression of this disease.

Renal expression of intercellular adhesion molecule-1 in immunoglobulin A nephropathy: tubulointerstitial injury and prognosis.

In immunoglobulin A nephropathy (IgAN), the abnormal expression of intercellular adhesion molecule-1 (ICAM-1) on proximal tubule epithelium is associated with the glomerular and interstitial infiltration of leucocytes, but its clinical significance remains uncertain. We analysed the relationship between the ICAM-1 (CD54) expression in tubular epithelial cells and interstitial leucocytes, macrophages (CD14) and T lymphocytes (CD3) with the histologic features, proteinuria and serum creatinine at the time of renal biopsy and after 2.42 years in 45 patients with IgAN and after 1.8+/-1.5 years in 29 patients with non-glomerulonephritis (non-GN). In IgAN, ICAM-1+ tubule epithelium was 0.1+/-0.18 (x+/-SD), and this was associated with extracapillary proliferation (up to 20% of Bowman's space), glomerular sclerosis involving less than 50% of glomerular area, interstitial cellular infiltration, tubular atrophy and proteinuria level. ICAM-1+ interstitial leucocytes were correlated with glomerular sclerosis involving less than 50% of glomerular area, glomerular sclerosis involving more than 50% of glomerular area, tubular atrophy, interstitial fibrosis and serum creatinine level. In patients with an increase of 50% in serum creatinine, ICAM-1+, CD14+ and CD3+, interstitial leucocytes were significantly outnumbered than in patients with stable serum creatinine. In non-GN, ICAM-1+ tubule epithelium was 0.02+/-0.04 (U=344, P<0.05, vs IgAN), and this was inversely correlated with the percentage of the normal glomeruli and associated with glomerular sclerosis covering more than 50% of glomerular area, tubular atrophy and serum creatinine level. The association between tubular ICAM-1 and proteinuria and the association between interstitial ICAM-1+, CD14+ and CD3+, leucocytes and renal failure at presentation and the deterioration in IgAN in contrast with non-GN suggest that tubular and interstitial expression of ICAM-1 may be a marker of tubulointerstitial disturbance in IgAN.

Circulating soluble adhesion molecules in ANCA-associated vasculitis.

BACKGROUND: To evaluate whether changes in concentrations of soluble (s) E-selectin, sP-selectin, sL-selectin, intercellular adhesion molecule 1 (sICAM-1), and vascular cell adhesion molecule 1 (sVCAM-1) reflect disease activity in patients with ANCA-associated vasculitis and whether serum levels of these adhesion molecules are related to the degree of renal failure in patients with chronic renal failure (CRF). SUBJECTS AND METHODS: A sandwich ELISA was used to measure these soluble adhesion molecules in (i) sera from 20 patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (10 patients with Wegener's granulomatosis (WG) and 10 patients with microscopic polyangiitis (MPA)), obtained at the time of diagnosis and during the remission period; (ii) sera from 40 patients with CRF not undergoing haemodialysis. RESULTS: At the time of diagnosis, serum levels of sE-selectin, sICAM-1 and sVCAM-1 (88+/-42 ng/ml, 437+/-184 ng/ml, 1720+/-1174 ng/ml respectively) were significantly higher in patients with ANCA-associated vasculitis than in healthy controls (P<0.0001, P=0.002 and P=0.001 respectively). Serum sP-selectin values did not differ from those obtained in normal donors. In contrast, sL-selectin levels (940+/-349 ng/ml) were significantly lower in patients than those recorded in healthy controls (P<0.0001). A significant decrease in concentrations of sE-selectin, sP-selectin, sICAM-1, and sVCAM-1 was observed between active and remission phases (P<0.0001, P=0.002, P=0.001 and P=0.001 respectively). No significant differences were observed in sL-selectin levels between active and remission phases. sL-selectin concentrations (802+/-306 ng/ml) during the remission phase remained lower than those observed in healthy controls (P<0.0001). No correlation was observed between serum creatinine and sE-selectin, sP-selectin, sICAM-1 and sVCAM-1 in patients of the CRF group. A slight negative correlation was established between creatinine and sL-selectin concentration. CONCLUSIONS: Increased serum levels of sE-selectin, sICAM-1, and sVCAM-1 and decreased levels of sL-selectin in active ANCA-associated vasculitis, and the normalization of sE-selectin, sICAM-1, and sVCAM-1 during the remission phase suggest that the concentration of soluble levels of these adhesion molecules reflects disease activity. The decrease in sP-selectin levels between active and inactive phases also suggest that this receptor may reflect clinical activity. The lack of correlation between serum levels of sE-selectin, sP-selectin, sICAM-1, and sVCAM-1 and the degree of renal failure in patients with CRF suggests that the mechanism of clearance of these molecules is not renal.

[Vancomycin and teicoplanin use as antibiotic prophylaxis in cardiac surgery: pharmacoeconomic study]. / Vancomicina y teicoplanina como profilaxis antibiótica en cirugía cardíaca: estudio farmacoeconómico.

BACKGROUND: To assess the economical impact of vancomycin use versus teicoplanin use as antibiotic prophylaxis for patients undergoing cardiac surgery for valve replacement (VR) and coronary artery by-pass (CABS) procedures. PATIENTS AND METHODS: This is an ancillary cost minimization analysis of a double blinded, parallel groups, randomised clinical trial (RCT), with the main objective of comparing the safety and efficacy of these antibiotics. 500 patients were included in the study; 267 in the CABS group and 233 in the VR group. The CABS patients received 1 g vancomicin or 400 mg teicoplanin, plus 150 mg netilmicin. The VR group received a second dose of each drug after extracorporeal circulation. In order to calculate the costs we considered the direct cost of the drug, the i.v. mix and the administration costs, together with personnel and structure costs. We considered two different situations: the administration of drugs within the surgical room theatre and in the medical ward. RESULTS: The demographic data of both groups were comparable. The frequency of severe adverse drug reactions (ADR) were similar (0.4%) in both groups, as well as the post-operative infection rates (8.6%). Differences were seen in the frequencies of low severity ADRs: 20.4% in the vancomycin group and 1.6% in the teicoplanin group. When the antibiotics were administered in the surgical room, among CABS patients the costs were 8,265 pts. for the teicoplanin group and 12,005 pts. for the vancomycin group; while among VR patients, costs were respectively 11,661 pts. and 14,528 pts. Administration costs of teicoplanin and vancomycin within a medical ward setting, however, the costs were 6,740 pts. and 2,809 pts. for CABS patients, and 5,308 pts. and 10,140 pts. for VR patients, respectively. CONCLUSIONS: The costs of antibiotic prophylaxis among cardiac surgery patients heavily depends on the setting and circumstances of drug administration. The minimization cost analysis indicates that teicoplanin is the most cost-effective option if the drug is administered within the surgical area, while vancomycin is the less costly option when administered within the medical ward. However, if the second option is to be chosen, it is necessary to assure the right plasmatic drug levels of the antibiotic at the beginning of the surgical procedure.

Acoustic analysis after radiotherapy in T1 vocal cord carcinoma: a new approach to the analysis of voice quality.

PURPOSE: The study of acoustic voice parameters (fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio) in extended vowel production, oral reading of a standard paragraph, spontaneous speech and a song in irradiated patients for Tis-T1 vocal cord carcinoma. METHODS AND MATERIALS: Eighteen male patients irradiated for Tis-T1 vocal cord carcinoma and a control group of 31 nonirradiated subjects of the same age were included in a study of acoustic voice analysis. The control group had been rigorously selected for voice quality and the irradiated group had previous history of smoking in two-thirds of the cases and a vocal cord biopsy. Radiotherapy patients were treated with a 6MV Linac receiving a total dose of 66 Gy, 2 Gy/day, with median treatment areas of 28 cm(2). Acoustic voice analysis was performed 1 year after radiotherapy, the voice of patients in extended vowel production, oral reading of a standard paragraph, spontaneous speech, and in a song was tape registered and analyzed by a Kay Elemetric's Computerized Speech Lab (model CSL# 4300). Fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio were obtained in each case. Mann Whitney analysis was used for statistical tests. RESULTS: The irradiated group presented higher values of fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio. Mann-Whitney analysis showed significant differences for fundamental frequency and jitter in vowel production, oral reading, spontaneous speech, and song. Shimmer only showed differences in vowel production and harmonics-to-noise ratio in oral reading and song. CONCLUSIONS: In our study only fundamental frequency and jitter showed significant increased values to the control group in all the acoustic situations. Sustained vowel production showed the worst values of the acoustic parameters in comparison with the other acoustic situations. This study seems to suggest that more work should be done in this field.

Cytokine-induced inflammation and long-term stroke functional outcome.

Inflammatory reactions are involved in the pathogenesis of cerebral ischemia. Cytokines exacerbate brain ischemic injury by several mechanisms and they activate the synthesis of acute-phase reactants. We evaluated the association between cytokine-induced inflammation and functional outcome in 41 patients with acute ischemic stroke. Blood samples for interleukin-1 receptor antagonist (IL-1ra), erythrocyte sedimentation rate (ESR), c-reactive protein (CRP) and polymorphonuclear leukocyte (PMNL) count were taken within 48 h from stroke onset. Functional outcome was assessed at six months with the Modified Rankin Scale. Patients with a Rankin score > or = 3 were classified as dependent outcome. The effect of inflammatory variables on outcome was analyzed by logistic regression. Mathew score <75 on admission, atrial fibrillation, non-lacunar infarct size, ESR>13 mm/h in men or >20 mm/h in women, PMNL count >8 x 10(9)/l, CRP>0.8 mg/dl and IL-1ra>500 pg/ml were associated with dependent outcome. On multiple logistic regression, severe stroke on admission, non-lacunar infarct size and ESR remain in the predictive model of outcome with a sensitivity and specificity of 76 and 80%, respectively. This study suggests that in addition to clinical evaluation and neuroimaging, measurement of ESR may be useful for the early detection of stroke patients with poor long-term functional outcome.
