AimTo compare the intraocular pressure (IOP) measurements obtained using the Pascal dynamic contour tonometer (PDCT) with the standard Goldmann applanation tonometry (GAT) and to correlate them with the central corneal thickness (CCT) in a non-glaucomatous population.MethodsWe prospectively measured IOP using PDCT and GAT in random order in 100 normal eyes. CCT was analysed with an ultrasonic pachymeter in each case. Statistical analysis of baseline and stratified data included intraclass correlation coefficient (ICC), Lin correlation, and Bland–Altman analysis to evaluate the agreement between both techniques.ResultsGAT was used first in 51 eyes and PDCT in 48 cases. Mean IOP was 14.8 mm Hg with GAT and 20.3 mm Hg with PDCT. Mean pachymetry was 553.23 micrometres (μm) (SD: 4.7 μm). Global agreement of IOP between GAT and PDCT was 0.09 by ICC and 0.170 by Lin correlation. When CCT values ranged between 540 and 545 μm, the agreement between both tonometers was optimal (ICC 0.54 and Lin 0.61). Outside these pachymetry values, agreement between both tonometers diminished dramatically.ConclusionStatistically significant agreement between both devices was reached only at intermediate pachymetry readings in contrast with other studies that show excellent global agreement between GAT and PDCT.Eye (2009) 23, 536–542; doi:10.1038/eye.2008.90; published online 28 March 2008 [ABSTRACT FROM AUTHOR]

Background: In this study, patients treated by thoracoscopic sympathicolysis for palmar hyperhidrosis were evaluated to determine the number and response of sweat glands to intradermal acetylcholine stimulus.Methods: A total of 30 patients were included in the study. Group A consisted of 10 patients with palmar hyperhidrosis who underwent thoracoscopic sympathicolysis in October 2005, and group B consisted of 20 patients who underwent surgery during the years 1999, 2000, and 2001. The study procedure involved applying iodine alcohol to the palm and then intradermally injecting 0.1 ml 1% acetylcholine. This activated the sweat glands, which were then photographed and counted. The study procedure was performed prospectively over different periods in group A and retrospectively in group B.Results: In group A, the mean number of glands activated 1, 3, 6, and 12 months after surgery were 41, 174.20, 522.8, and 747.2, respectively; this gradual increase was statistically significant over the first 6 months (p = 0.004) but not between months 6 and 12 (p = 0.255). The trend towards an increasing number of active glands occurred in both groups, with a mean of 1369.8 active glands in group B compared to 747.2 (p = 0.095) in group A after 12 months.Conclusion: It is well-known that Cannon's law of denervation (1939) is not applicable to the sweat glands, that is, there is no hyperactivation following intradermal acetylcholine stimulation. However, some response, which increased over the first 6 months following surgery, was observed in our study. Nevertheless, this activation is subsequently self-limiting, resulting in no gland atrophy, and reinnervation occurs without patient awareness. [ABSTRACT FROM AUTHOR]

Emerging data suggest that costimulation blockade with belatacept effectively controls humoral alloimmune responses. However, whether this effect may be deleterious for protective anti-infectious immunity remains poorly understood. We performed a mechanistic exploratory study in 23 kidney transplant recipients receiving either the calcineurin-inhibitor tacrolimus (Tac, n=14) or belatacept (n=9) evaluating different cellular immune responses after influenza vaccination such as activated T follicular Helper (Tfh), plasmablasts and H1N1 hemagglutinin (HA)-specific memory B cells (HA + mBC) by flow-cytometry, and anti-influenza antibodies by hemagglutination inhibition test (HI), at baseline and days 10, 30 and 90 post-vaccination. The proportion of CD4+CD54RA-CXCR5+ Tfh was lower in belatacept than Tac patients at baseline (1.86%[1.25-3.03] vs 4.88%[2.40-8.27], p=0.01) and remained stable post-vaccination. At M3, HA + mBc were significantly higher in Tac-treated patients (0.56%[0.32-1.49] vs 0.27%[0.13-0.44], p=0.04) and correlated with activated Tfh numbers. When stratifying patients according to baseline HA + mBc frequencies, belatacept patients with low HA + mBC displayed significantly lower HA + mBc increases after vaccination than Tac patients (1.28[0.94-2.4] vs 2.54[1.73-5.70], p=0.04). Also, belatacept patients displayed significantly lower seroprotection rates against H1N1 at baseline than Tac-treated patients (44.4% vs 84.6%) as well as lower seroconversion rates at days 10, 30 and 90 after vaccination (50% vs 0%, 63.6% vs 0%, and 63.6% vs 0%, respectively). We show the efficacy of belatacept inhibiting T-dependent antigen-specific humoral immune responses, active immunization should be highly encouraged before starting belatacept therapy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Pernin, Meneghini, Torija, Jouve, Del Bello, Sanz-Muñoz, Eiros, Donadeu, Polo, Morandeira, Navarro, Masuet, Favà, LeQuintrec, Kamar, Crespo and Bestard.)

Objectives: The aims of present study were to analyze the mortality risk factors in patients who had surgery for acute pancreatitis and to assess the importance of culturing peripancreatic tissue or fluid infection to ascertain the infection status., Methods: Surgery was indicated both in patients with infected severe acute pancreatitis and in those with sterile pancreatitis with an unfavorable course. During surgery, cultures were taken of tissues (pancreatic necrosis and peripancreatic fat), intra-abdominal fluid, and bile., Results: Of 107 patients operated on, fluid culture was analyzed in 94 patients, pancreatic necrosis in 61 patients, peripancreatic fat in 39 patients, and bile in 38 patients. Sterile pancreatitis with sterile ascites was found in 17 patients, sterile pancreatitis with infected ascites in 22, and pancreatic tissue infection in 60. Multivariate analysis demonstrated that sterile tissue cultures, age over 65 years, and fewer than 12 days between the beginning of pain and surgery were risk factors for mortality. Sterile pancreatitis with sterile ascites and sterile pancreatitis with infected ascites had similar postoperative mortality (41% and 50%, respectively); the group with pancreatic tissue infection had a lower mortality (20%)., Conclusions: Early surgery, advanced age, and sterility of tissue cultures have been demonstrated as mortality factors for acute pancreatitis. Intra-abdominal fluid may be infected in the presence of sterile necrosis.

Objective: Traveler's diarrhea (TD) is the most frequent disease among people from industrialized countries who travel to less developed ones, especially sub-Saharan Africa, Southern Asia and South America. The most common bacteria causing TD is enterotoxigenic Escherichia coli (ETEC). The WC/rBS cholera vaccine (Dukoral) has been shown to induce cross-protection against ETEC by means of the B subunit of the cholera toxin. The aim of the study was to evaluate the effectiveness of the WC/rBS cholera vaccine in preventing TD., Methods: Between May 1 and September 30 (2007), people seeking pre-travel advice in ten Spanish international vaccination centers were included in a prospective cohort study of travelers to cholera risk countries. The incidence rates of TD were adjusted for variables whose frequencies were statistically different (entry point 0.10) between the vaccinated and non-vaccinated cohorts., Findings: The vaccinated cohort (n = 544 travelers) included people vaccinated with the WC/rBS cholera vaccine, and the non-vaccinated cohort (n = 530 travelers) by people not vaccinated. The cumulative incidence rate of TD was 1.69 in vaccinated and 2.14 in non-vaccinated subjects. The adjusted relative risk of TD in vaccinated travelers was 0.72 (95% CI: 0.58-0.88) and the adjusted vaccination effectiveness was 28% (95% CI: 12-42)., Conclusions: The WC/rBS cholera vaccine prevents TD in 2 out of 7 travelers (preventive fraction: 28%). The number needed to vaccinate (NNV) to prevent 1 case of TD is 10.

Background: Thoracoscopic bilateral sympathicolysis of the T3 sympathetic ganglia is an effective treatment for palmar hyperhidrosis, though not without potential complications and consequences such as Horner's syndrome. The objective of our study is to evaluate the repercussion of T3 sympathetic denervation on pupillary tone in patients with primary hyperhidrosis., Methods: A prospective descriptive study of 25 patients (50 pupils) ranging in age from 18 to 40 years with an indication of T3 sympathectomy for palmar hyperhidrosis or palmar-plantar hyperhidrosis from 1 December 2009 to 31 December 2010 was carried out. We excluded all patients with previous eye surgery or other ocular pathologies and those with pathologies that contraindicate denervation surgery and ocular study. All patients were evaluated before surgery and at 24 h and 1 month after sympathetic denervation. Pupil/iris (P/I) ratio was measured before and after instillation of sympathicomimetic eye drops containing 1% apraclonidine., Results: No statistically significant differences were found when we compared the preoperative P/I ratio of the left eyes versus the right eyes (P = 0.917). We found statistically significant differences (P < 0.001) between the preoperative P/I ratio [0.40 mm (standard deviation, SD 0.07 mm)] and the postoperative basal ratio [0.33 (SD 0.05)] at 24 h. The P/I ratio at 24 h increased from 0.33 to 0.36 (SD 0.09), a nonsignificant increase (P = 0.45), after instillation of medicated eye drops. No differences were observed between the preoperative [0.40 (SD 0.07)] and 1-month basal values [0.38 (SD 0.07)], and instillation of apraclonidine no longer induced a hypersensitivity response., Conclusions: T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis, even though this impairment is not generally evident on standard physical examination or reported by patients. This subclinical dysfunction may be caused by injury to an undefined group of presympathetic nerve cell axons in caudocranial direction that communicate with the cervical sympathetic ganglia and whose function is mydriatic pupillary innervation.

Although evidence supports that colorectal cancer (CRC) has an environmental etiology, the potential influence of diet appears to be one of the most important components. We studied the relation between food groups and nutrient intake and the risk of CRC. A hospital-based case-control study was conducted in Spain between 2007 and 2009. The authors matched 245 patients with incident histologically confirmed CRC by age, gender, and date of admission with 490 controls. Information about nutrient intake was gathered by using a semiquantitative frequency food questionnaire. Univariate analysis was done with individual food items. Odds ratios (ORs) for consecutive tertiles of nutrient intake were computed after allowance for sociodemographic variables and consumption of food groups. Vitamin B6 (OR: 0.26), vitamin D (OR: 0.45), vitamin E (OR: 0.42), polyunsaturated fatty acids (OR: 0.57), and fiber (OR: 0.40) were inversely associated with CRC, whereas carbohydrates (OR: 1.82) were significantly associated with CRC risk for the upper tertile. In multivariate analysis adjusting for major covariables (energy, age, and gender), vitamin D (OR:0.45), vitamin E (OR:0.36), and fiber (OR:0.46) remained associated with CRC. Data suggest that the etiology of colorectal cancer is not due to lifestyle and dietary patterns being important the effect of single nutrients.

Background: Major pulmonary resections for early-stage non-small-cell lung cancer (NSCLC) are increasingly being performed by thoracoscopy, but there are economic concerns related to the use of many disposable items and increased operative time. We evaluated and compared the costs of thoracoscopic lobectomy versus open lobectomy., Methods: Data from all patients who underwent lobectomy for clinical stage I NSCLC from January 1, 2007, to December 31, 2009 were reviewed. Two hundred eighty-seven major pulmonary resections (269 lobectomies and 18 anatomic segmentectomies) for NSCLC were performed: 98 cases via a totally endoscopic approach (TS) and 189 via a classical posterolateral thoracotomy (PLT). Direct medical costs [hospital stay, intensive care unit (ICU) stay, disposables, theatre time, laboratory, and radiology costs] were evaluated., Results: Patient demographics were similar in both groups. The two groups did not differ in histology, pathologic stage, or type of lobectomy. There were no differences in postoperative complications or readmissions during the 30-day postoperative period; however, patients in the TS group had significantly fewer chest tube days and shorter hospital length of stay (p < 0.001). Theatre costs were significantly higher in the TS group [2,861 ± 458 vs. 2,260 ± 399 (p < 0.001)]. Mean cost for disposables for TS was 1,800 ± 560.46 vs. 901 ± 328 for PLT (p < 0.001). Thoracoscopic upper-right lobectomy and anatomic segmentectomy were more expensive than other thoracoscopic lobectomies. Mean costs for hospital stay, laboratory, and radiological services for TS were less than for PLT (p < 0.001), although mean ICU stay was similar in both groups. Finally, overall costs were significantly greater for the PLT group (14,145.57 ± 7,117.84) than for the TS group (11,934.13 ± 6,690.25) (p < 0.001)., Conclusion: Thoracoscopic lobectomy was less expensive than open lobectomy for patients with early-stage NSCLC. Although thoracoscopic lobectomy has a higher initial cost, overall cost is less expensive due to a shorter hospital stay.

Background: Results for the e4/e2 alleles of the ApoE gene as markers of susceptibility, clinical and radiological progression, and cognitive deterioration in patients with multiple sclerosis (MS) are contradictory., Aim: The usefulness of these markers in predicting the response to interferon-β-1b (IFNβ-1b) was evaluated., Material and Methods: 95 patients with relapsing-remitting MS treated with IFNβ-1b (mean follow-up 7.44 years) were studied. We correlated the e4 and e2 alleles with the time to the first relapse or to a 1-point worsening on the Expanded Disability Status Scale, time to moderate disability, progression index, and treatment discontinuation due to inefficacy., Results: We found no association between the e4 allele and any of the variables. The e2 allele was associated with increased time to moderate disability., Conclusion: The e4 allele of ApoE has no prognostic value for the response to IFNβ-1b. The e2 allele delayed the progression of disability in our MS patient cohort., (Copyright © 2011 S. Karger AG, Basel.)

Introduction: Surgery is the accepted treatment in adenocarcinoma of the head of the pancreas; however, the long-term survival continues to be low. The aim of this study is to define prognostic factors of long-term survival after cephalic duodenopancreatectomy due to pancreatic adenocarcinoma., Material and Methods: We have collected data on the treatment of adenocarcinoma of the head of the pancreas (ADHP) by means of a cephalic duodenopancreatectomy (CDP) performed n the Bellvitge University Hospital (Barcelona) from 1991 to 2007., Results: A total of 204 CDP due to ADHP were performed. The histology showed that the resected tumour was larger than 3cms in 70 cases, with lymphatic infiltration in 73%, perineural invasion in 89%, and lymphatic involvement in 89%. More than 15 lymph nodes were resected in 120 patients. A total of 113 (60%) patients received adjuvant treatment after surgery. There were 148 (73%) deaths, of which 55 (27%) were alive at closure. The actual mean survival was 2.54 years (95% CI; 2.02-3.07) and an actuarial survival at 5 years of 13.55% (95% CI; 7.69-19.41). The study of mortality risk factors showed that, female gender, absence of peri-operative transfusion (p=0.003), the resection of more than 15 lymph nodes during the operation (P=0.004), and the administration of adjuvant treatment (p=0.004) had a better long-term prognosis. The multivariate analysis showed that transfusion and gender were the most significant variables., Conclusions: Surgery of head of the pancreas adenocarcinoma must include an adequate lymphadectomy, and must be performed with a low morbidity and without the need of a peri-operative transfusion., (Copyright © 2010 AEC.

Introduction: Cephalic duodenopancreatectomy (CDP) is the treatment of choice in cancer of the head of the pancreas. However, it continues to have a high post-surgical morbidity and mortality. The aim of this article is to define variables that influence post-surgical morbidity and mortality after cephalic duodenopancreatectomy due to pancreatic adenocarcinoma (PA) cancer of the head of the pancreas (CHP)., Material and Methods: The variables were prospectively collected form patients operated on between 1991 and 2007, in order to investigate the factors of higher morbidity., Results: A total of 204 patients had been intervened due to PA, of whom 57 were older than 70 years. Of these patients, 119 had a CPD, 11 extended lymphadenectomy, 66 with pyloric conservation, and 8 with extension to total pancreatectomy due to involvement of the section margin. Portal or mesenteric vein resection was included in 35 cases. Post-surgical complications were detected in 45% of cases, the most frequent being: slow gastric emptying (20%), surgical wound infection (17%), pancreatic fistula (10%), and serious medical complications (8%). Further surgery was required in 13%, and the over post-surgical mortality was 7%. A patient age greater than 70 years, post-surgical haemoperitoneum, gastroenteric dehiscence, and the presence of medical complications were post-surgical mortality risk factors in the multivariate analysis. Pancreatic fistula was not a factor associated with post-surgical mortality., Conclusions: Cephalic duodenopancreatectomy is a safe technique but with a considerable morbidity. Patients over 70 years of age must be carefully selected before considering surgery. Serious medical complications must be treated aggressively to avoid an unfavourable progression., (Copyright © 2010 AEC. Published by Elsevier Espana. All rights reserved.)

Objective: Accurate preoperative staging is essential to provide the best treatment for lung cancer. The objective of the present study was to determine agreement between preoperative and surgical-pathological staging and to analyse the impact of any disparity on treatment., Methods: This is a descriptive study of a series of 176 lung cancer cases treated by surgery between 2005 and 2007. Preoperative staging was based on clinical information and computed tomography (CT), positron emission tomography (PET), PET-CT, bronchoscopy and mediastinoscopy. In all cases, surgical-pathological staging was based on the analysis of surgical samples and the findings during surgery. Both preoperative and pathological stage determination were based on the TNM (tumour, node, metastasis) classification established in 1997. Concordance was measured by calculating agreement rates and the kappa value., Results: Preoperative and surgical-pathological staging agreed in 102 cases, an agreement rate of 58% and kappa value of 0.54 (95% confidence interval (CI) 0.44-0.63). The highest kappa value (0.68, 95% CI 0.53-0.82) was obtained in stage IA patients. Patients who underwent PET or PET-CT had a better kappa index (0.56, 95% CI 0.45-0.67, vs 0.39, 95% CI 0.21-0.56). Surgical-pathological staging validated surgery in 145 cases (82%), while 21 (12%) were revised to stage IIIA N2 and 10 (6%) to non-surgical stages., Conclusions: Global agreement between preoperative and surgical-pathological staging was moderate. The best agreement was found in stages IV and IA., (Copyright (c) 2009 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V. All rights reserved.)

Background: Endoscopic bilateral thoracic sympathicolysis (EBTS) is an effective and minimally invasive procedure used for patients with primary hyperhidrosis. The purpose of this study was to examine plantar hyperhidrosis before and after EBTS., Methods: A total of 198 patients with primary hyperhidrosis underwent 396 thoracoscopic sympathicolysis of ganglia T2-T3 in a prospective study. All completed a preoperative questionnaire, followed by a second questionnaire 12 months after the operation. The questionnaires evaluated sweating in the different body areas. Only the zones of anhydrosis were considered in delimiting the cutaneous expression of sympathetic ganglia T2-T3., Results: Redistribution of perspiration as reported by the patients comprised significant reductions in palmar and axillary hyperhidrosis, and an increase in the zone of the trunk and popliteal region. The incidence of plantar anhydrosis and plantar hypohidrosis was 30.3% and 20.7%, respectively (p < 0.001)., Conclusions: EBTS is followed by redistribution of body perspiration, with, and important, plantar anhydrosis and hypohidrosis. Although EBTS is the standard treatment for palmar primary hyperhidrosis, we must continue studying baseline sympathetic activity in patients affected by primary hyperhidrosis and the neuroanatomy of the sympathetic system to understand the redistribution of sweating and decrease of hyperhidrosis in the zones regulated by mental or emotional stimuli.

The BrucellaCapt test is an immunocapture agglutination test suggested as a possible substitute for the Coombs test in the diagnosis of human brucellosis. Here it is compared with classical tests using 321 samples from 48 patients with brucellosis (6.9 +/- 1.7 samples per patient), including 20 patients with focal disease and 8 patients with a total of 9 relapse episodes (mean follow-up, 18 months). The BrucellaCapt test was used according to the manufacturer's instructions, and we also used a variant of the BrucellaCapt test in which the microtiter plates were not coated with antibodies against total human immunoglobulin (BCAPV). The correlation between the BrucellaCapt and BCAPV tests was 0.982 (P < 0.001), with 260 coincident pairs of titers (81%). The areas under the receiver operating characteristic curve for the BrucellaCapt and BCAPV tests with respect to the Coombs test were 0.969 and 0.960, respectively. Upon admission, the BrucellaCapt, BCAPV, and Coombs tests and the microagglutination test (MAT) were positive for all cases: titers were 1/2,560 by the BrucellaCapt test, 1/2,560 by the BCAPV test, 1/1,280 by the Coombs test, and 1/320 by the MAT. The decreases in the BrucellaCapt and BCAPV titers over time were pronounced in comparison with the Coombs titers. Cumulative probabilities of persistence 12 months after therapy were as follows: 80% by the BrucellaCapt test, 80% by the BCAPV test, 87% by the Coombs test, and 35% by the MAT. Serological changes during relapse were detected in seven cases (88%) by the Coombs test, in five cases by the BrucellaCapt and BCAPV tests, and in three cases by the MAT. The BrucellaCapt test is a sensitive, specific, and simple test for routine use in human brucellosis. Similar results were obtained with the BCAPV test. However, in some cases of relapse and chronic forms of the disease, the slight changes observed in low-affinity antibodies alone are better detected by the Coombs test.

Aim: To assess lifetime substance abuse, family history of alcohol abuse/dependence, and novelty seeking in three different eating disorder groups (anorexia nervosa-restrictive; anorexia nervosa-binge eating/purging; anorexia nervosa to bulimia nervosa)., Method: A total sample of 371 eating disorder patients participated in the current study. Assessment measures included the prevalence of substance abuse and family history of alcohol abuse/dependence as well as the novelty-seeking subscale of the Temperament and Character Inventory-Revised., Results: Significant differences across groups were detected for lifetime substance abuse, with anorexia nervosa-restrictive individuals exhibiting a significant lower prevalence than the anorexia nervosa to bulimia nervosa and anorexia nervosa-binge eating/ purging patients (P < 0.01). For family history of alcohol abuse/dependence the same pattern was observed (P = 0.04). Novelty seeking was associated with substance abuse (P = 0.002), with the anorexia nervosa to bulimia nervosa group exhibiting significantly higher scores on the novelty-seeking scale than the other two groups (P < 0.001). But family history of alcohol abuse/dependence was not related to novelty seeking (P = 0.092)., Conclusion: Lifetime substance abuse appears to be more prevalent in anorexia nervosa patients with bulimic features. Higher novelty-seeking scores may be associated with diagnosis cross-over.

Introduction: It is not properly estimated the cigarette consumption after a relapse compared with the consumption before a smoking cessation therapy. The aim of this study was to know if tobacco consumption among relapsed smokers that visited a smoking cessation unit is higher or lower than consumption preceding dishabituation therapy and the related factors to this consumption change., Subjects and Methods: 1,516 smokers who received a multicomponent program for smoking cessation have been studied. The percentage of reduction after the relapse in relation to previous consumption and the consumption difference with regard to basal variables among 994 relapsed smokers has been calculated. A logistic regression model was used in order to analyze the predictors to reduce more than 50% of previous cigarette consumption., Results: Relapsed patients smoked 20.4% less than before the smoking cessation therapy. Smokers with chronic obstructive pulmonary disease, and with the age of 50 years or more, had the highest rate of reduction consumption. The best predictors for cigarette reduction were those of low nicotine dependence and being heavy smokers., Conclusions: Heavy smokers or low nicotine dependence smokers have a higher probability to reduce their cigarette consumption. Other predictor variables are age of more than 50 years, high previous consumption or previous abstinence period of more than 6 months.

Objective: The main symptom of sleep apnea-hypopnea syndrome (SAHS) is excessive daytime sleepiness. The self-administered Functional Outcomes of Sleep Questionnaire (FOSQ) was designed to evaluate the impact of sleepiness on a patient's daily life. The aim of this study was to determine the scores of patients with SAHS and of healthy individuals on the Spanish version of the FOSQ and to assess its usefulness for evaluating the impact of excessive sleepiness in patients with suspected SAHS., Population and Methods: Thirty-one patients with SAHS diagnosed by conventional polysomnography and 31 healthy individuals were included in the study. The following data were collected: patient information; use of tobacco, alcohol, or street drugs; blood pressure; and sleep schedule. Sleepiness was assessed on the Epworth Sleepiness Scale and the impact of sleepiness on activities of daily living by the FOSQ., Results: Patients with SAHS (apnea-hypopnea index, 57) had a mean FOSQ total score of 88.7; healthy individuals had a mean score of 110.9 (P< .001) Significant differences were found between the 2 groups on all the FOSQ subscales, except for the one that measured social outcome. There was a moderate correlation between the 2 questionnaires (r=--0.54; P=.01) and between FOSQ and the AHI (r=--0.39; P=.05). While the capacity to predict SAHS, based on receiver operating characteristic curves was greater for the Epworth Sleepiness Scale than for the FOSQ (area under the curve, 0.91 and 0.77, respectively), the diagnostic yield increased when both questionnaires were considered together., Conclusions: We obtained FOSQ reference scores for Spanish patients with SAHS and for healthy individuals. The study showed that the Spanish version of the FOSQ is a good instrument for assessing the impact of excessive sleepiness on activities of daily living in patients with suspected SAHS.

Background and Objective: We performed an analysis of early factors influencing the outcome of Cushing's disease treated by transsphenoidal pituitary surgery., Patients and Method: Prospective study of 29 patients who underwent transsphenoidal pituitary surgery for Cushing's disease. The prognostic value of preoperative and operative variables, histological findings and serum cortisol (measured at 8:00 a.m. the day after surgery) were analyzed., Results: Of the 29 patients included in this study, 26 achieved postoperative remission while in 3 patients treatment failed. Tumor was identified at histology in 92.3% patients in the remission group and in 33.3% in the failure group, this difference being significant (p = 0.03). Median postoperative cortisol levels were 95.8 nmol/l in the remission group and 676 nmol/l in the failure group, this difference being significant (p = 0.024). Serum cortisol of 600 nmol/l correctly classified the remission and failure groups with a sensitivity of 100% and a specificity of 96%., Conclusions: In our experience, no identification of an adenoma at histology and an early postoperative cortisol level higher than 600 nmol/l after transsphenoidal pituitary surgery for Cushing's disease was associated with a high risk of failed treatment.

Aims: To assess the effect of partner smoking status on the success of a cessation program., Design: Prospective cohort., Setting: Smoking Cessation Unit in Hospital of Bellvitge (Hospitalet de Llobregat, Barcelona)., Participants: A total of 1516 smokers of 10 or more cigarettes who started a smoking cessation program between January 1995 and December 2001 were included., Measurements: All patients gave information about smoking history and smoking partner status. Abstinence was determined by carbon monoxide exhaled., Findings: Significant differences were found in the abstinence rates at 12 months by smoking partner status: abstinence was achieved by 28.3% of patients with smoking partner, and by 46.5% of patients without smoking partner (p<0.001). Subjects whose partner was smoking at the beginning of the program appear to be more likely to relapse than subjects without smoking partners (p<0.001) and this is more pronounced in women than in men. However no significant gender differences were found in any group of smoking partner status., Conclusions: Having a smoking partner is a determinant of relapse 1 year after the beginning of the cessation program. Interacting not just with the smoker, but also with his or her partner, could neutralize interpersonal influences making smokers more accessible to behavioural and pharmacological techniques.

The annual cost of a screening program to detect methicillin-resistant Staphylococcus aureus (MRSA) in a teaching hospital in Spain was 10,261 Euro. The average cost per MRSA infection was 2,730 Euro; therefore, the cost of the program would be covered if it only prevented 4 infections per year (11% of the total number of MRSA infections at our hospital).

Background: Factors associated with compliance with smoke-free policies among hospitalized smokers are poorly described. A better understanding of these factors may improve smoking cessation during admission and in the long-term., Methods: Two cross-sectional studies were conducted in an urban teaching hospital in Spain during 2002 and 2004. We interviewed 229 admitted smokers gathering data on smoking history, admission diagnosis, belief that hospitalization is related to smoking, policy's awareness, and smoking during admission and place of smoking., Results: Among hospitalized patients, approximately a third were current smokers. The compliance with the nonsmoking policy in 2002 and 2004 was respectively 71.9% (IC95%: 63.9-79.9) and 60.1% (IC95%: 50.9-69.3). In the multivariate regression model, factors significantly associated with compliance were: contemplation stage, confidence in quitting after discharge, belief that current symptoms or illness were related to smoking, and mild withdrawal symptoms., Conclusions: Admission in a smoke-free hospital does not guarantee that patients will refrain from smoking. Factors associated with compliance identified may be modified by tailored smoking cessation interventions. Our results might help physicians to understand inpatients' difficulties to abstain from cigarettes and enhance their efforts to take advantage of the hospitalization as a window opportunity to quit.

Background and Objective: We aimed to assess the distribution of the lymphoid neoplasms and their histological subtypes in accordance with the World Health Organization (WHO) classification by calculating their incidences rates in our area., Patients and Method: From January 1994 to December 2001, 1,288 patients diagnosed with lymphoid neoplasms were recruited in the population-based Cancer Registry of Girona. Former pathological and hematological diagnoses were reviewed and some were prospectively reclassified following the latest WHO classification., Results: Following criteria established by WHO classification the distribution of lymphoid neoplasms was as follows: 77.3% B-cell neoplasm, 5.9% T-cell neoplasm, 8.7% Hodgkin lymphoma and 8,2% was unclassifiable. From 1994 TO 2001 the lymphoid neoplasm crude incidence rates was 35.8 per 100,000 men-year, while it was 25.7 new cases per 100,000 women-year. In children (< 15 years old), precursor B-lymphoblastic lymphoma/leukemia (65%) and Hodgkin lymphoma (20%) were the most frequent lymphoid neoplasm, whereas myeloma (17.8%), diffuse large B-cell lymphoma (13.5%) showed the highest incidence rate in adults., Conclusions: A higher incidence rate of lymphoid neoplasms was found in men in our area compared with other geographical areas in Spain, which could suggested a faster approximation to the pattern observed in industrialized societies. The cause of this geographical distribution is unknown.

Objective: To determine and compare the practice of periodic preventive mammography in women aged 50-69 years in the eight health regions of Catalonia in 1994 and 2002., Methods: Data from the 1994 and 2002 Catalan Health Survey Interview were used. A cross-sectional survey of a representative sample of the non-institutionalized population of Catalonia was performed. All women aged 20 years old or older who directly answered the questionnaire (5,986 and 3,265 women in 1994 and 2002, respectively) were included. The influence of age, social class, type of health insurance and health region was evaluated using multivariate logistic regression analysis., Results: In 1994, women aged 40-49 years reported a higher proportion of mammographic screening (42.8% of women in this age group) than the other groups, while in 2002 the highest proportion (76.3%) was observed in women aged 50-59 years. Rates of screening mammography in women aged 50-69 years were 26.9% in 1994 and 69.1% in 2002, increasing in all health regions and reducing differences among regions. In 1994 and 2002 women in the most advantaged social classes (I, II and III) reported higher proportions of mammographic screening than those in social class V, although this gap was smaller in 2002., Conclusions: The practice of preventive periodic mammography has significantly increased in women in the target group (women aged 50-69 years). Preventive mammography was lower in non-targeted age groups except in the group of women aged 40-49 years old, in which it was significantly increased. No significant differences in the practice of mammographic screening were observed among health regions in 2002.
