Abstract
INTRODUCTION Mohs surgery was first described by Frederic Mohs in 1941 to eliminate high-risk cutaneous tumors. The technique involves histological examination of the margins. OBJECTIVE The aim of this study was to describe the clinical findings and compare the grade and subclinical extension of the tumor as measured by the number of Mohs stages needed for complete elimination according to whether the tumor presented high-risk factors. METHODS We included 100 patients with 105 tumors. In all cases, age, sex, tumor site, tumor type, histological subtype in the case of basal cell carcinoma, size, recurrences, number of Mohs stages, and reconstruction technique were recorded. RESULTS The study group comprised 44 men and 56 women aged between 28 and 88 years (mean, 72.6 years). Of the tumors, 80 % corresponded to basal cell carcinoma, 12.38 % to squamous cell carcinoma, 4.76 % to dermatofibrosarcoma protuberans, 0.95 % to Merkel cell carcinoma, 0.95 % to microcystic adnexal carcinoma, and 0.95 % to lentigo maligna melanoma. Most tumors were located on the head and 60 % required more than one Mohs stage for complete elimination. CONCLUSION This series is characterized by a high percentage of high-risk cutaneous tumors. After assessing the risk factors independently, we found that the size of the tumor is the risk factor most closely related to grade and subclinical extension in the case of basal cell carcinoma, although similar conclusions cannot be drawn for the other types of tumor studied.

Abstract
The objective of this paper was to evaluate the effect of constant rate infusion of medetomidine on the anaesthetic requirements of desflurane in dogs. For this, six healthy dogs were studied. Measurements for baseline were taken in the awake, unsedated dogs, then each dog received intravenously (i.v.) three anaesthetic protocols: M (no medetomidine infusion), M0.5 (infusion of medetomidine at 0.5 microg/kg/h, i.v.) or M1 (infusion of medetomidine at 1 microg/kg/h, i.v.). All dogs were sedated with medetomidine (2 microg/kg, i.v.) and measurements repeated in 10 min. Induction of anaesthesia was delivered with propofol (3 mg/kg, i.v.) and maintained with desflurane for 90 min to achieve a defined surgical plane of anaesthesia in all cases. After tracheal intubation infusion of medetomidine was initiated and maintained until the end of anaesthesia. Cardiovascular, respiratory, arterial pH (pHa) and arterial blood gas tensions (PaO(2), PaCO(2)) variables were measured during the procedure. End tidal desflurane concentration (EtDES) was recorded throughout anaesthesia. Time to extubation, time to sternal recumbency and time to standing were also noted. Heart rate and respiratory rate were significantly decreased during sedation in all protocols compared to baseline values. Mean heart rate, mean arterial pressure, systolic arterial pressure, diastolic arterial pressure, respiratory rate, tidal volume, arterial oxygen saturation, end-tidal CO(2), pHa, PaO(2), and PaCO(2) during anaesthesia were similar for all protocols. EtDES for M (8.6 +/- 0.8%) was statistically higher than for M0.5 (7.6 +/- 0.5%) and M1 (7.3 +/- 0.7%) protocols. Infusion of medetomidine reduces desflurane concentration required to maintain anaesthesia in dogs.

Abstract
Centralised treatment of domestic sewage coming from A Coruña city (250000 inhabitants) and several medium and small size villages (up to 15000 inhabitants) together with industrial estate effluents was planned. The area population is about 380000 inhabitants and the overall effluent will reach about 600000 equivalent inhabitants. The characteristics of different streams will determine the treatment alternatives and pre-treatment requirements for individual streams. Domestic sewage from A Coruña showed medium to high organic content (741 mg l(-1) of COD), while domestic sewage from small villages (Lorbé, Oleiros) and industrial estates (Sabón, A Grela) showed a high variability in organic content, with COD concentration ranging from 100 to 4000 mg L(-1) or more. About 50-65% COD corresponded to suspended solids, although some industrial effluents showed lower values. Characterized industrial effluents had lower concentration of nutrients (nitrogen and phosphorus) and higher concentration of sulphate and alkalinity than domestic sewage. Anaerobic biodegradability was about 80% for domestic sewage, and ranged from 20 to 100% for industrial estate effluents. Furthermore, some industrial streams showed high microbial toxicity. The results indicate that anaerobic treatment of these effluents is of interest. However, specific pre-treatment for some individual streams or the adoption of minimisation and prevention measures in order to reach total or partial detoxification is suggested.

Abstract
21180 Background: Recently, inmunophenotypic characterization methods have allowed identification of female breast carcinomas into separate groups showing different behaviour and response to therapy: luminal A phenotype (RE +, HER2-neu - ), luminal B (RE +, HER2- neu + ), basal like (RE -, HER2-neu - ). In this study, we used immunohistochemistry to investigate the inmunophenotypic profile distribution of male breast cancer. Methods: all the male breast cancers were obtained from the files of the Departments of Pathology of Hospital Río Carrión in Palencia, Spain, since 1996. A total of 9 cases were reviewed to confirm the diagnosis and to characterize each tumour. The following CK immunohistochemistry was performed: 8/18 and 5 (Dako, Carpinteria, CA, USA) in a Dako autostainer. ER was interpreted as positive if > 10% of the cells were staining. Normal skin and tonsils were used as positive controls for the CK and a known breast cancer for the ER immunohistochemistry. Results: five cases expressed RE and were HER2-neu negative, so they have a luminal-A phenotype. The four cases that expressed the luminal-B pehnotype expressed RE and HER2-neu; we demonstrated gene amplification of the HER-neu gene using fluorescent in situ hybridisation (FISH) in those cases. Respect the CKs profile, all cases were positive for CK 8/18 and negative with CK 5, vimentin and p63, characteristic of luminal-like CK expression profile, according wiht the literature. Conclusions: this is the first case series of male breast cancer patients that provides inmunophenotypic profile data on this rare disease in only one center in Spain. We comunicate that the vast majority of these tumours express the phenotype of luminal-like CKs. None of our patients were basal-like tumours. The percentage expression of Her-2 parallels the finding in female breast cancers and this should be analysed for its predictive significance, according to new specific biological treatments. No significant financial relationships to disclose.

Abstract
The increasing deployment of mobile communication base stations led to an increasing demand for epidemiological studies on possible health effects of radio frequency emissions. The methodological challenges of such studies have been critically evaluated by a panel of scientists in the fields of radiofrequency engineering/dosimetry and epidemiology. Strengths and weaknesses of previous studies have been identified. Dosimetric concepts and crucial aspects in exposure assessment were evaluated in terms of epidemiological studies on different types of outcomes. We conclude that in principle base station epidemiological studies are feasible. However, the exposure contributions from all relevant radio frequency sources have to be taken into account. The applied exposure assessment method should be piloted and validated. Short to medium term effects on physiology or health related quality of life are best investigated by cohort studies. For long term effects, groups with a potential for high exposure need to first be identified; for immediate effect, human laboratory studies are the preferred approach.

Abstract
Treatment of chronic hepatitis C in human immunodeficiency virus (HIV)-infected patients is associated with low response rates and high incidence of side effects. One hundred twenty-one hepatitis C virus (HCV)-HIV-coinfected patients were randomized to receive interferon alpha-2b (3 MU thrice weekly; n = 61) or peginterferon alpha-2b (1.5 microg/kg/week; n = 60), plus ribavirin (800 mg daily), for 24 (genotype 2 or 3) or 48 weeks (genotype 1 or 4). We assessed early virological response at 4, 8 and 12 weeks to predict sustained virological response (SVR). Safety assessment included frequent blood lactate measurement and relative quantitation of mitochondrial DNA (mtDNA) content in peripheral blood mononuclear cells. In intention-to-treat analysis, the SVR rate was higher in the peginterferon group (55%vs 26%; P = 0.002). The difference for HCV genotypes 1 and 4 was 45%vs 14% (P = 0.009) and 50%vs 27% (P = 0.387), respectively, and for genotype 2 or 3, 71%vs 43% (P = 0.12) Viral response at 4, 8 and 12 weeks of treatment was highly predictive of SVR. Among genotype 3 patients, 17 of 20 (85%) whose HCV RNA was already undetectable at 4 weeks had an SVR after 24 weeks of treatment. Hyperlactataemia occurred in 22 patients and was clinically significant in six, two of whom died. mtDNA decreased significantly 4-12 weeks after the start of treatment in patients developing clinically significant hyperlactataemia. Peginterferon alpha-2b plus ribavirin was more effective than interferon alpha-2b plus ribavirin in HIV-coinfected patients. Frequent monitoring of virological response may be very helpful to optimize treatment compliance, to tailor treatment duration and to minimize side effects.

Abstract
The objective of this paper was to evaluate romifidine as a pre-medicant in dogs prior to propofol-isoflurane anaesthesia, and to compare it with medetomidine. For this, eight healthy dogs were anaesthetised. Each dog received three pre-anaesthetic protocols: R40 (romifidine, 40 microg/kg, IV), R80 (romifidine, 80 microg/kg, IV) or MED (medetomidine, 10 microg/kg, IV). Induction of anaesthesia was delivered with propofol and maintained with isoflurane. The following variables were studied before sedative administration and 10 min after sedative administration: heart rate (HR), mean arterial pressure (MAP), systolic arterial pressure (SAP) and diastolic arterial pressure (DAP) and respiratory rate (RR). During maintenance, the following variables were recorded at 5-min intervals: HR, MAP, SAD, DAP, arterial oxygen saturation (SpO(2)), end-tidal CO(2)(EtCO(2)), end-tidal concentration of isoflurane (EtISO) required for maintenance of anaesthesia and tidal volume (TV). Time to extubation, time to sternal recumbency and time to standing were also registered. HR and RR experimented a significantly decreased during sedation in all protocols respect to baseline values. Mean HR, MAP, SAP, DAP, SpO(2), EtCO(2), and TV during anaesthesia were similar for the three protocols. End tidal of isoflurane concentration was statistically similar for all protocols. Recovery time for R40 was significantly shorter than in R80 and MED. The studied combination of romifidine, propofol and isoflurane appears to be an effective drug combination for inducing and maintaining general anaesthesia in healthy dogs.

Abstract
The aim of the study was to assess the incidence and the cumulative probability of cytolytic and cholestatic hepatotoxicity during antiretroviral treatment in a group of HIV HCV haemophiliacs. We evaluated 47 patients that received 246 courses of antiretroviral treatment [98 courses of pre-highly active antiretroviral therapy (pre-HAART) and 148 HAART treatments]. Liver function tests were assessed at baseline of each treatment, after 1 month and at least every 4 months thereafter. Cytolytic and cholestatic hepatotoxicity was recorded. Of the 246 treatments, 28 (12.45%) were followed by cytolytic hepatotoxicity and 32 (13%) by cholestatic hepatotoxicity. Cytolytic hepatotoxicity was similar in HAART (16/148; 10.8%) and in pre-HAART treatment (12/98; 12.2%) and cholestatic hepatotoxicity was more frequent in HAART (29/148; 19.6%) than in pre-HAART treatment (3/98; 3.1%) (P < 0.001). The actuarial probability of developing cytolytic and cholestatic hepatotoxicity at 10 years of onset of antiretroviral treatments was 39% and 56%, respectively. Most enzyme elevations were asymptomatic, but in eight cases therapy was discontinued or changed and in one case a cirrhotic patient died of progressive liver failure. In HIV HCV haemophiliacs, the cumulative probability of developing hepatotoxicity during follow-up is high and although in the most cases the toxicity is mild, fatal cases can occur.

Abstract
Different start-up procedures of an upflow anaerobic sludge bed (UASB) digester were carried out. Start-up without inoculum (experiment A) was delayed for about 120 day. The digester reached 75-85% total suspended solids (TSS) removal, 54-58% total chemical oxygen demand (TCOD) removal and 63-73% biological oxygen demand (BOD5) removal at influent concentrations of 240-340 mg TCODil-1, temperatures of 13.5-15 degrees C and hydraulic retention times (HRT) of 10-11 h. Digested sludge was used as inoculum in experiment B. After the start-up period of 75 days, digester efficiencies were 58%, 41% and 54% for TSS, TCOD and BOD5 removal, respectively, working at 169 mg TCODil-1, temperature of 14 degrees C and HRT of 11 h. The sludge bed developed and stabilised quickly when using a hydraulically adapted inoculum (experiment C), but TCOD and BOD5 removals remained low and volatile fatty acids (VFA) accumulated in the effluent.

Abstract
The objective of this study was to evaluate dexmedetomidine as a premedicant in dogs prior to propofol-desflurane anaesthesia, and to compare it with medetomidine. Six healthy dogs were anaesthetized. Each dog received intravenously (i.v.) five preanaesthetic protocols: D1 (dexmedetomidine, 1 microg/kg, i.v.), D2 (dexmedetomidine, 2 microg/kg, i.v.), M1 (medetomidine, 1 microg/kg, i.v.), M2 (medetomidine, 2 microg/kg, i.v.), or M4 (medetomidine, 4 microg/kg, i.v.). Anaesthesia was induced with propofol (2.3-3.3 mg/kg) and maintained with desflurane. The following variables were studied: heart rate (HR), mean arterial pressure, systolic arterial pressure, diastolic arterial pressure, respiratory rate (RR), arterial oxygen saturation, end-tidal CO2, end-tidal concentration of desflurane (EtDES) required for maintenance of anaesthesia and tidal volume. Arterial blood pH (pHa) and arterial blood gas tensions (PaO2, PaCO2) were measured during anaesthesia. Time to extubation, time to sternal recumbency and time to standing were also recorded. HR and RR decreased significantly during sedation in all protocols. Cardiorespiratory variables during anaesthesia were statistically similar for all protocols. EtDES was significantly different between D1 (8.1%) and D2 (7.5%), and between all doses of medetomidine. Desflurane requirements were similar for D1 and M2, and for D2 and M4 protocols. No statistical differences were observed in recovery times. The combination of dexmedetomidine, propofol and desflurane appears to be effective for induction and maintenance of general anaesthesia in healthy dogs.

Abstract
This study aimed to investigate whether initial treatment of experimental pulmonary aspergillosis with high loading doses can be used as an alternative to standard therapeutic regimens. Steroid-immunosuppressed rats, infected intratracheally with Aspergillus fumigatus, received either amphotericin B deoxycholate (d-AmB) 1 mg/kg/day, liposomal amphotericin B (L-AmB) 5 mg/kg/day, or underwent a 3-day course of L-AmB 10 mg/kg, or 10 mg/kg for the first 3 or 4 days of treatment, followed by 3 mg/kg until the end of treatment. Therapy started 24 h after fungal challenge and lasted for 7 days. Compared to controls, survival was improved significantly in animals receiving any L-AmB regimen (p <or= 0.003), but not d-AmB. Compared with d-AmB, L-AmB at initial doses of 10 mg/kg followed by 3 mg/kg/day was consistently more effective, but only when measured in terms of survival, lung weight and glucosamine levels, and not log CFU. Despite the absence of significant differences between any of the L-AmB regimens, a trend towards better response rates with the higher loading dose was observed.

Abstract
The purpose of this study was to evaluate the incidence and etiology of bacterial and fungal infection or contamination in lung allograft donors and to assess donor-to-host transmission of these infections. Recipients who survived more than 24 h and their respective donors were evaluated. The overall incidence of donor infection was 52% (103 out of 197 donors). Types of donor infection included isolated contamination of preservation fluids (n = 30, 29.1%), graft colonization (n = 65, 63.1%) and bacteremia (n = 8, 7.8%). Donor-to-host transmission of bacterial or fungal infection occurred in 15 lung allograft recipients, 7.6% of lung transplants performed. Among these cases, 2 were due to donor bacteremia and 13 to colonization of the graft. Twenty-five percent of donors with bacteremia and 14.1% of colonized grafts were responsible for transmitting infection. Excluding the five cases without an effective prophylactic regimen, prophylaxis failure occurred in 11 out of 197 procedures (5.58%). Donor-to-host transmission of infection is a frequent event after lung transplantation. Fatal consequences can be avoided with an appropriate prophylactic antibiotic regimen that must be modified according to the microorganisms isolated from cultures of samples obtained from donors, grafts, preservation fluids and recipients.

Abstract
BACKGROUND To quantify the incidence of flu in different groups of the population of Navarra in the 2004-2005 season, and to evaluate the effectiveness of anti-flu vaccination. METHODS The analysis of influenza cases in the system of compulsory notificable diseases was complemented by the individualised notifications in the network of sentinel doctors that covers a population of 22,339 inhabitants. The coverage and effectiveness of the vaccine was studied. RESULTS Vaccine coverage in (3)65 year olds reached 62%. The incidence of influenza was 42.6 cases per 1,000 inhabitants. It reached a maximum in mid-January, exceeding 750 weekly cases per 100,000 inhabitants and 1,900 cases per 100,000 children. The highest rate of influenza was observed in under-15 year olds (49.4 cases per 1,000 inhabitants) and the lowest in non-institutionalised (3)65 year olds (2.6 per 1,000 inhabitants), although it was higher in geriatric residences (62.1 per 1,000; p<0.0001). Seventy-nine percent of the cases from 5 to 64 years resulted in absenteeism from school or work. The flu virus was identified in 42/65 (65%) nasopharyngeal smears, 90% being influenza virus A(H3). The incidence of influenza was 3.08% in the unvaccinated and 0.45% in the vaccinated (p<0.001). The global effectiveness of the anti-flu vaccine was 65%, and in (3)65 years old it was 73%. CONCLUSION Although its effectiveness is not total, the vaccine is the main measure for preventing influenza. The network of sentinel doctors provide useful information for the coordination of care and public health activities against flu.

Abstract
Disseminated intravascular coagulation (DIC) can be a rare initial manifestation of adenocarcinoma of the prostate. We present a case in which DIC was the symptom leading to the suspicion of a prostatic tumour. The performance of a prostate biopsy in this situation exacerbated the initial coagulation disorder. This case highlights the risks of prostate biopsy in patients with a suspicion of advanced adenocarcinoma of the prostate. The difficulty of treating DIC in this clinical situation is also discussed.

Abstract
Depressive symptoms are common in epilepsy. To determine associations between depression and demographic, clinical, and pharmacological factors among epileptic patients, we conducted a cross-sectional survey. We evaluated 241 epileptic outpatients at a neurological center in a 6-month period. Depressive syndrome was diagnosed when both the Montgomery-Asberg Scale and the Beck Depression Inventory were rated above the standard cutoff points. Bivariate and multivariate analyses were performed to assess the differences between depressed and nondepressed patients with respect to demographic, clinical, and pharmacological features. Depressive syndrome was diagnosed in 42.7% of patients (n=103). Factors associated in the bivariate analysis were: cryptogenic etiology, posttraumatic epilepsy, use of primidone, and inadequate seizure control. After logistic regression, inadequate seizure control (OR 3.08, 95% CI 1.40-6.77, P=0.005) and use of primidone (OR 4.08, 95% CI 2.09-7.98; P<0.001) remained significantly associated. Depression was common and associated with inadequate seizure control and use of primidone.

Abstract
CLINICAL CASE We report the case of a 25 year old woman who attended our Hospital with a pigmented lesion in anterior chamber angle of her right eye. She complained of reduced visual acuity on the same eye. On examination, and once complementary tests were performed, a pigmented lesion located on the iris root and ciliary body of her right eye was confirmed. A decision to perform a local resection was made and there were no surgical complication. Histology results confirmed the diagnosis of ciliary body melanocytoma. DISCUSSION Ciliary body melanocytoma is a benign rare lesion with only 40 cases described in the literature. A local resection of this benign lesion should be considered as alternative to enucleation, even though differential diagnosis with malignant melanoma must also be considered.

Abstract
Introduction Alternation of antiretroviral drug regimens has been proposed as a novel treatment strategy for HIV infection. However, some concerns persist regarding antiviral efficacy, adherence, toxicity and resistance evolution in the long term. Methods A total of 161 antiretroviral-naive HIV-1-infected patients were randomized to receive stavudine/ didanosine/efavirenz (group A) or zidovudine/lamivudine/ nelfinavir (group B) or to alternate between the two regimens every 3 months starting with regimen A (group C). Antiviral efficacy, adherence, safety and tolerability were analysed every 12 weeks. Results After 96 weeks, time to virological failure was significantly delayed in the alternating regimen compared with the standards of care regimens. Virological suppression was seen in 46%, 48% and 58% of patients in groups A, B and C, respectively, in the intention-to-treat analysis and in 75%, 76% and 97% in the on-treatment analysis (A vs C: P=0.014; B vs C: P=0.016; A vs B: P=0.849). At the end of the study, 94% of patients in group A and 92% in groups B and C reported an adherence greater than 95%. Alternating therapy was associated with a similar impact on CD4+ counts in comparison with the standards of care regimens, as well as a lower mitochondrial DNA/nuclear DNA (mtDNA/nDNA) ratio decrease in the mitochondrial substudy performed on 37 patients. The frequency and intensity of adverse events in the alternating group decreased during subsequent cycles. Discussion Our results favour the hypothesis that proactive therapy switching may delay the accumulation of resistance mutations. Moreover, the alternating regimen was well tolerated and adherence remained comparably high in all treatment groups. The lower mtDNA/nDNA ratio decrease observed in this group may imply a lower impact on mitochondrial toxicity than in standard regimens.

Abstract
OBJECTIVES To describe the methods used to impute HIV seroconversion date in the haemophiliac cohorts from GEMES project and to validate its use. METHOD 632 haemophiliacs coming from three hemophilia units identified as HIV+ and 1.092 individuals coming from 5 project GEMES cohorts with a seroconversion window (time among test HIV and HIV+) less than 3 years where mid point (PM) was assumed as seroconversion date. For both groups, seroconversion date was imputed after estimating the probability distribution of seroconversion by means of the EM algorithm. Two imputation methods are used: one obtained from the expected value and the other from the geometric mean of 5 random samples. from the estimated distribution. Imputations have been validated in the non haemophiliacs cohorts comparing with the PM seroconversion date. Also AIDS free time and survival from the different seroconversion imputed dates were compared. RESULTS Median seroconversion date is located in May of 1993 for the non haemophiliacs and in 1982 for the haemophiliacs. Not big differences are observed among the imputed seroconversion dates and the mid-point seroconversion date in the non-haemophiliac cohorts. Similar results are found for the haemophiliac cohorts. Also no differences are observed in the estimated AIDS-free time for both groups of cohorts. CONCLUSIONS Geometric mean imputation from several random samples provides a good estimate of the HIV seroconversion date that can be used to estimate AIDS-free time and survival in haemophiliac cohorts where seroconversion date is ignored.
