Abstract
BACKGROUND Ectomesenchymomas (EMs) are extremely rare neoplasms composed of malignant mesenchymal components and neuroectodermal derivatives. They are described in a wide variety of locations, with the head and neck region being one of the most frequently involved areas. EMs are usually managed as high-risk rhabdomyosarcomas and have similar outcomes. METHODS We present the case of a 15-year-old female with an EM that arose in the parapharyngeal space and extended into the intracranial space. RESULTS Histologically, the tumor presented an embryonal rhabdomyosarcomatous mesenchymal component and the neuroectodermal component was constituted by isolated ganglion cells. Next-generation sequencing (NGS) revealed a p.Leu122Arg (c.365 T > G) mutation in the MYOD1 gene, a p.Ala34Gly mutation in the CDKN2A gene, and CDK4 gene amplification. The patient was treated with chemotherapy. She died 17 months after the debut of symptoms. CONCLUSION(S) To our knowledge, this is the first reported case in English literature of an EM with this MYOD1 mutation. We suggest combining PI3K/ATK pathway inhibitors in these cases. NGS should be performed in EMs cases to detect mutations with potential treatment options.

Abstract
Abstract
Background
It is well known that statins, ezetimibe and other lipid lowering treatments such as Evolocumab (PCSK9-Inhibitor) reduce cardiovascular events by decreasing LDL-cholesterol (LDL-C) levels and slowing the progression of coronary atherosclerosis. Nevertheless, cardiovascular (CV) risk remains. Alirocumab, a PCSK9 inhibitor has demonstrated a reduction in cardiovascular events but its relationship with coronary atherosclerosis reduction has not been adequately demonstrated.
Purpose
The ARCHITECT trial sought to determine whether Alirocumab 150 mg/2 weeks is able to stop or reverse coronary atherosclerosis progression, by assessing coronary plaque burden (CPB) by serial multidetector computed tomography (MDCT).
Methods
A total of 104 patients with molecularly characterized heterozygous familial hypercholesterolaemia (FH) without clinical cardiovascular disease were enrolled in this trial. Patients had to have CPB >30% as documented by MDCT, be on maximum tolerated statin therapy with or without ezetimibe and LDL-C >100 mg/dL. Patients underwent a MDCT at enrollment and after 18-month treatment with alirocumab and they were analyzed by means of QAngio CT (Medis medical imaging system, the Netherlans). The pre-specified primary endpoint was change in CPB.
Results
Median age was 53.3 (46.2–59.4) years (54, 51.9% woman). Median LDL-cholesterol was 138.9 mg/dL. There was a significant reduction in the primary endpoint as Alirocumab reduced CPB from 34.6 (32.9–36.8)% to 30.4 (27.4–33.4)%. Significant reductions in LDL-C (67%) and atherosclerotic plaque volume were also found. Plaque regression as estimated by CPB was found in 91 (87.5%) patients. Main resuts may be found in figure 1.
Conclusions
Alirocumab demonstrated significant regression of CPB on MDCT over 18 months. ARCHITECT provides crucial mechanistic clues on coronary plaque behavior under the use of Alirocumab and its results could link and explain ODYSSEY-OUTCOMES results.

Abstract
OBJECTIVE To analyze the incidence of chronic pain 5 months after episiotomy, as well as potential prognostic factors. METHODS A prospective cohort observational study was conducted on pregnant women age≥18 years who had undergone an episiotomy. The presence of pain was evaluated in the area of episiotomy at 24 and 48 h of delivery using a structured face-to-face questionnaire, and by telephone questionnaire at 5 months. The primary endpoint was the presence of persistent pain at 5 months. A record was made of the presence of pain at delivery, and its intensity, the presence or absence of epidural analgesia, instrumental delivery, perineal tear, and pain when episiotomy was performed, as well as the presence of dyspareunia and urinary incontinence at 5 months post-episiotomy. RESULTS A total of 87 parturient patients were included, of whom 78 completed the study. Of the patients who completed the study, 12.8% reported chronic episiotomy pain. Epidural analgesia was associated with a higher incidence of instrumental delivery and less pain at the time of episiotomy and expulsion (P<.0005, P<.02, and P<.01, respectively). Chronic pain is associated with operative delivery (P<.017), and with the presence of pain at rest at 24 and 48 h (P<.01), of wound complications (P<.026), and of dyspareunia (P<.001). CONCLUSION An incidence of 12.8% of women developing chronic pain after delivery with episiotomy suggests a health problem. More studies are needed to confirm our results.

Abstract
Weakly haemolytic anaerobic intestinal spirochaetes of the genus Brachyspira are commonly identified based on species-specific gene sequences. Apart from the pathogenic Brachyspira pilosicoli, the distribution and disease associations of the other weakly haemolytic Brachyspira species in pigs have not been comprehensively investigated. In this study weakly haemolytic Brachyspira isolates (n=67) from Spanish and Portuguese pigs with diarrhoea, negative in a routine diagnostic PCR for B. pilosicoli, were identified by sequencing their NADH oxidase genes (nox). Nearly half the isolates were identified as Brachyspira murdochii (n=31; 46.3%). The others were Brachyspira innocens (n=26; 38.8%), Brachyspira intermedia (n=7; 10.4%), "Brachyspira pulli" (n=1; 1.5%) and a potentially novel Brachyspira species (n=2; 3%). Multilocus sequence typing (MLST) on a subset of 18 isolates confirmed their species designations, including the potential new species, and identified similarities to strains from other countries.

Abstract
Many drivers tend to foster the development of renewable energy production in wastewater treatment plants as many expectations rely upon energy recovery from sewage sludge, for example through biogas use. This paper is focused on the assessment of grease waste (GW) as an adequate substrate for co-digestion with municipal sludge, as it has a methane potential of 479-710 LCH(4)/kg VS, as well as the evaluation of disintegration technologies as a method to optimize the co-digestion process. With this objective three different pre-treatments have been selected for evaluation: thermal hydrolysis, ultrasound and enzymatic treatment. Results have shown that co-digestion processes without pre-treatment had a maximum increment of 128% of the volumetric methane productivity when GW addition was 23% inlet (at 20 days of HRT and with an OLR of 3.0 kg COD/m(3)d), compared with conventional digestion of sewage sludge alone. Concerning the application of the selected disintegration technologies, all pre-treatments showed improvements in terms of methane yield (51.8, 89.5 and 57.6% more for thermal hydrolysis, ultrasound and enzymatic treatment, respectively, compared with non-pretreated wastes), thermal hydrolysis of GW and secondary sludge being the best configuration as it improved the solubilization of the organic matter and the hydrodynamic characteristics of digestates.

Abstract
Leiomyomatosis peritonealis disseminata (LPD) is an uncommon condition characterized by multiple nodules of smooth muscle within the peritoneal cavity. It usually occurs during reproductive age, and is especially associated to exogenous and endogenous exposure to female gonadal steroids. A limited number of cases of malignant transformation have been reported in the literature. We report a case of leiomyomatosis peritoneais disseminata with sarcomatous degeneration in a 37-year-old nulligravid patient with no exposure to exogenous estrogen or progesterone, revealed by increased abdominal perimeter. The imaging techniques showed occupation of the entire peritoneal cavity by bulky solid masses. The patient underwent a total hysterectomy with bilateral salpingo-oophorectomy and tumoral mass resection. The histopathologic diagnosis was leiomiomatosis peritonealis disseminata with leiomyosarcomatous degeneration. The patient was given systemic chemotherapy with tumoral progression, and died 24 months after the initial diagnosis.

Abstract
OBJECTIVE To evaluate the characteristics of patients on whom long-term Video-EEG monitoring is performed in a specialist centre and to assess its suitability to study refractory epilepsy patients. METHODS A prospective analysis and study of Video-EEG monitoring was performed in a series of 100 refractory epilepsy patients from a single centre. The analysis included demographic data, the time until the first seizure, the methods used to provoke seizures, and the outcome (usefulness, change in the management, pharmacological and surgical improvement). A subgroup analysis based on diagnosis was performed. RESULTS The study was performed mainly on young people (mean 34.4 years) and the first seizure appeared in a mean of 30hours, requiring most of the patients to withdraw the medication. Nevertheless, there were no cases of status epilepticus. The usefulness of the test was high in all the groups. The management was changed in 65% of the patients with pharmacological and surgical improvement. CONCLUSION Long-term Video-EEG monitoring is a suitable test to study refractory epilepsy patients. The main problem in our country is accesibility.

Abstract
This study is the first conducted in Spain to evaluate antimicrobial susceptibility of field isolates of Brachyspira hyodysenteriae. One hundred and eight isolates of the bacterium, recovered from different Spanish swine farms between 2000 and 2007, were investigated. The minimum inhibitory concentrations (MIC) of erythromycin, tylosin, tiamulin, valnemulin, clindamycin and lincomycin were determined using a broth microdilution technique. Most of the isolates showed poor susceptibility to erythromycin (MIC(90)>256 microg/ml), tylosin (MIC(90)>256 microg/ml), clindamycin (MIC(90)>4 microg/ml) and lincomycin (MIC(90)=128 microg/ml). Reduced susceptibility to tiamulin and valnemulin was observed with a MIC>2 microg/ml in 17.6% and 7.41% of the B. hyodysenteriae isolates, respectively. Moreover, a survival analysis permitted the detection of an increasing trend in the MIC values for almost all the antimicrobials used in the treatment of swine dysentery when comparing recent isolates (from 2006 to 2007) with those recovered in earlier years (between 2000 and 2004).

Abstract
The present study is the first conducted in Spain to estimate the bacteriological herd prevalence of Salmonella enterica in fattening units and to describe the Salmonella serovar diversity on these farms using a sample representative of the entire swine population. For this purpose, 10 faecal samples were collected from 10 different pens containing pigs close to market weight in a total of 232 fattening units. Total sample size was proportionally distributed according to the fattener census in each of the regions of the country and all the samples were examined by culture of 25 g of faecal material. One hundred (43.1%) farms had at least one Salmonella-positive sample (95% CI: 37-49.1%). Salmonella enterica was detected in 290 (12.5%) pooled faecal floor samples (95% CI: 11.2-13.8%). The apparent herd prevalence of salmonellosis was similar among multi-site, finishing and farrow to finish farms. Overall, 24 different serovars were identified, with S. Typhimurium, S. Rissen and S. Derby being the most common both at herd and sample level. Results of phage typing were available for the 91 isolates of S. Typhimurium. A total number of 10 different phage types were identified, with DT 193 being the most frequent. Phage types DT 104, DT 104b and DT U302, which have been associated with several multi-resistant patterns, accounted for 23% and 29% of the Typhimurium total isolates or Typhimurium infected farms respectively.

Abstract
BACKGROUND Maculopapular exanthema has been reported to be the most frequently drug-induced cutaneous reaction. Although T lymphocytes are involved in the pathomechanism of this disease, little is know about the recruitment of these cells to the skin. OBJECTIVE The aim of this work is to study the role of the chemokines TARC/CCL17 and MDC/CCL22 in the lymphocyte trafficking to affected skin in drug-induced exanthemas. METHODS Real-time PCR was performed to quantify gene expression levels of CCL17, CCL22 and their receptor CCR4 in lesional skin biopsies and in peripheral blood mononuclear cells from patients. CCL27 and CCL22 proteins were detected in the skin by immunochemistry. Protein expression of CCR4 was determined by flow cytometry in peripheral blood lymphocytes. Functional migration assays to CCL17 and CCL22 were assessed to compare the migratory responses of peripheral blood lymphocytes from patients and healthy subjects. RESULTS CCL17 and CCL22 were up-regulated in maculopapular exanthema-affected skin. CCR4 mRNA levels and protein expression were increased in peripheral blood mononuclear cells during the acute phase of the disease. The increased expression of the receptor was consistent with a higher response of peripheral blood lymphocytes to CCL17 and CCL22 compared with the migratory response in healthy donors. CONCLUSION TARC/CCL17 and MDC/CCL22 might cooperate in attracting T lymphocytes to skin in drug-induced maculopapular exanthemas.

Abstract
A patient with atypical infantile Pompe disease suffered acute respiratory insufficiency at the age of 8 years which resulted in complete immobilization and dependence on assisted ventilation. Shortly after initiation of enzyme replacement therapy, she regained her mobility and, after 20 months of treatment, she now leads an almost normal life with limited restrictions.

Abstract
We describe a continuous flow mode of ventilation for repair of type I esophageal atresia in an infant. This type of atresia is defined by distal stenosis of the esophagus with a proximal blind pouch and no connection to the tracheobronchial tree. In traditional repair procedures the surgical approach is by thoracotomy, but newer videoassisted thoracoscopic techniques have introduced novel challenges to ventilatory mechanics in these low-weight infants. The literature contains little discussion of the anesthetic management or respiratory mechanics of these patients. Trying to maintain adequate tidal volume and oxygenation while thoracoscopic maneuvers take place increases the risk of barotrauma. Single-lung ventilation with a continuous flow respirator was effective in the case we report.

Abstract
Lymphocyte proliferative responses were evaluated in mucosal (mesenteric lymph nodes) and systemic (spleen and blood) lymphoid tissues of conventional piglets inoculated with the virulent or attenuated isolates of porcine epidemic diarrhoea virus (PEDV) strain CV-777 and challenged 21 days later with the virulent isolate of the same virus. A lymphoproliferative assay was developed in which mononuclear cells isolated from lymphoid tissues at different postinoculation and postchallenge days underwent a secondary in vitro stimulation with semipurified antigen obtained from PEDV-infected cell cultures. Vigorous lymphocyte proliferative responses were detected in the pigs inoculated with the virulent PEDV at postinoculation days 4-21, especially in the mesenteric lymph nodes and the blood; however, in the spleen this response was lower and less regular. The pigs inoculated with the attenuated virus showed a less intense response, the higher lymphocyte proliferation also corresponded to the mononuclear cells from mesenteric lymph nodes. Lymphocyte proliferation responses showed high correlations with protection against homologous challenge with virulent PEDV, and this correlation was higher in the gut associated lymphoid tissues (mesenteric lymph nodes). The cell proliferation response detected in blood mirrored that detected in the mesenteric lymph nodes, and showed also good correlation with protection. The results confirm that T-cell-helper function, assessed by lymphocyte proliferation responses, contributes to establishing a protective immune response against PEDV infections.

Abstract
Eleven-day-old conventionally reared piglets were inoculated orally with two different doses of the cell-culture adapted strain CV-777 of the porcine epidemic diarrhoea virus (PEDV) or the virulent isolate of the same strain and challenged with the same virulent PEDV 3 weeks later. Pigs inoculated with the two doses of the attenuated virus did not show any typical sign of the disease, and virus shedding was not frequent. In contrast, 31% of pigs exposed to the virulent PEDV developed diarrhoea and virus shedding was demonstrated in 100%. At different postinoculation day (PID) and postchallenge day (PCD) virus-specific antibody-secreting cells (ASC) in gut associated lymphoid tissues (duodenum and ileum lamina propria and mesenteric lymph nodes) and systemic locations (blood and spleen) were assessed by enzyme-linked immunospot (ELISPOT). Only a small response was detected in the groups inoculated with attenuated PEDV, whereas in the group previously exposed to the virulent virus on PID 21 a large number of IgG and IgA ASC was detected. Isotype-specific antibody responses in serum were investigated by ELISA. IgG responses were detected in all groups, although the highest response corresponded to the group inoculated with virulent virus and only this group showed an IgA response. The pigs exposed to virulent PEDV were completely protected against the challenge with a higher dose of the same virulent virus on PID 21 and none of them shed the virus. The pigs inoculated with the attenuated strain were partially protected against the challenge, and 25% of the low dose- and 50% of the high dose-exposed pigs did not shed virus after challenge. All the pigs from a control group, not previously exposed to the virus, excreted the virus in faeces. A strong positive correlation was established between protection and the ASC responses detected in gut associated lymphoid tissues and blood at the challenge day and also between protection and serum isotype-specific antibody titers on that day. In addition, the IgA and IgG ASC responses detected in the blood on PID 21 also correlated with the responses found in the gut associated lymphoid tissues. The ASC and serum antibody responses after the challenge corresponded to a secondary immune response in the groups inoculated with attenuated virus, whereas a primary response was evident in the control group. No increase was seen in any of the parameters studied in the pigs inoculated with virulent PEDV.

Abstract
An enzyme-linked immunospot (ELISPOT) has been developed to detect porcine epidemic diarrhea virus (PEDV)-specific antibody secreting cells (ASC) in gut associated lymphoid tissues (duodenum and ileum lamina propria and mesenteric lymph nodes) and systemic locations (spleen and blood) of conventional pigs so as to characterise the mucosal and systemic antibody response generated by the infection with PEDV. A total number of 28 eleven-day-old conventional pigs were orally inoculated with the field isolate of the PEDV strain CV-777. Diarrhea was observed in 32% of the pigs and virus shedding was demonstrated in 100% between postinoculation day (PID) 1 and 8. Serum IgG and IgA antibodies to PEDV were detected by isotype ELISA from PID 12 and 15, respectively, reaching maximum values at PID 32 (IgG) and 21 (IgA). PEDV specific IgM ASC occurred in all the tissues between PID 4 and 7, with the strongest response in the intestinal lamina propria. IgA and IgG ASC responses were evident in the intestinal lymphoid tissues from PID 21, the highest number of specific ASC corresponded to the duodenum lamina propria. In the systemic lymphoid tissues the number of IgG and IgA ASC detected were lower than in the mucosal tissues, however, in the blood, presence of IgA ASC was constantly detected from PID 14 until the end of the experiment. Memory antibody response to the PEDV was also studied by secondary in vitro stimulation of the mononuclear cells (MNC) isolated from mesenteric lymph nodes, spleen and blood. The memory B cell response was prominent at PID 21 and 25 and consisted in IgG and IgA ASC. To our knowledge, this is the first report to research into the presence and distribution of specific ASC in different locations of the systemic and the gut associated lymphoid tissues after a PEDV infection as well as the presence of memory B cells.

Abstract
Intestinal samples and/or lymph nodes of two Iberian pigs from two different farms were submitted for histopathologic examination. Both pigs had proliferation of ileal and/or cecal crypts with almost complete absence of goblet cells. Infection by Lawsonia intracellularis was demonstrated by immunohistochemistry and polymerase chain reaction assay. The mesenteric lymph node of one pig had moderate lymphocyte depletion with granulomatous inflammation of the lymph node parenchyma. Histiocytes and multinucleated giant cells from the lymph node of one pig contained L. intracellularis antigen within the cytoplasm. This pig had also porcine circovirus type 2 (PCV-2) infection, but nucleic acid and antigen of this virus were not demonstrated in the lymph node. The second pig had lymphocyte depletion and marked granulomatous inflammation in Peyer's patches. Histiocytes and multinucleated giant cells in areas of granulomatous inflammation contained L. intracellularis antigen; no PCV-2 nucleic acid or antigen was detected in the tissues of this pig. This is the first description of granulomatous ileitis and lymphadenitis associated with L. intracellularis infection.

Abstract
OBJECTIVE Considerable controversies exist about the psychological impact of dentofacial deformities and the effects of treatment on body image. This research, which is a part of a longitudinal prospective study about a number of psychological aspects of adult patients with severe dentofacial deformities treated by orthognatic surgery, assesses the body image of a sample of patients before and after treatment. METHOD Two subscales, general and facial-oclusal, of the modified Secord and Jourard test were used to evaluate body image of a sample of orthognatic surgery patients (N = 58). The questionnaires were completed at four time points: one week before surgery (T0), and one (T1), six (T6) and twelve months (T12) after surgery. RESULTS Despite the severity of dentofacial deformity, presurgical mean scores of both subscales of body image test were normal. T6 scores were significantly higher than normative levels in both subscales (p < 0.001). T6 scores were also significantly higher than T0 in both general (p < 0.05) and facial-oclusal subscales (p < 0.001). T12 measurements showed significant differences in both subscales with respect to normative levels but significant differences between T12 and T0 were only found in facial oclusal subscale (p < 0.001). No differences were found between T12 and T6 scores. CONCLUSION The positive effect of orthognatic surgery on body image is encouraging, but longer follow up is needed to evaluate the persistence of results and the eventual occurrence of any late change.

Abstract
Tumors of the clival and parapharyngeal areas are a challenge because of their location. They used to be considered inaccessible because the aggressive approaches employed caused elevated levels of morbidity. This fact led to more conservative approaches that attempted to preserve the exposure of the lesion. These approaches were a combination of cranial and facial procedures, thus utilizing a combined effort between neurosurgeons and maxillofacial surgeons. We described our experience with a partial segmented Le Fort I osteotomy added to a transmandibular approach to expose a chordoma of the clivus and left parapharyngeal space. A three-dimensional imaging was used as a diagnostic tool and to plan the optimal surgical approach. The operative technique was described in this case study. Some important technical details of the approach are described. The global outcome was favorable.

Abstract
OBJECTIVE To determine the feasibility of the intracerebroventricular injection of phenytoin (PHT), phenobarbital (PB) and carbamazepine (CBZ) to control seizures in the amygdala kindling model in the rat, and also to determine the associated neurotoxic effects. METHODS Different doses of PHT (500 and 1250 microl), PB (200, 500 and 1000 microl) and CBZ (200 and 500 microl) were injected intracerebroventricularly into amygdala kindled male Wistar rats. Seizures were induced with a fixed suprathreshold stimulus of 500 microA at times between 15 and 60 min after the injection. Seizure intensity (Racine's scale), latency, seizure duration and afterdischarge duration were measured. Neurotoxicity was tested using ataxia and sedation scales and also using a rotorod. RESULTS PB was found to be the most powerful anticonvulsant, and both PB and CBZ caused significant reductions in seizure intensity to less than stage 3 with the doses tested. PHT only reduced seizures for the first 15-30 min after application. PB was also the most toxic drug, followed by CBZ and by PHT. Neurotoxicity was acceptable except in the cases of the highest doses during the earliest periods tested. There was no mortality due to the injection of any of the drugs at the doses employed. CONCLUSIONS The intracerebroventricular route is a feasible way to administer anticonvulsant drugs for seizure control in the kindling model.

Abstract
The possible existence of an increased susceptibility to the reinforcing properties of morphine was analyzed in male and female rats born from mothers exposed to delta9-tetrahydrocannabinol (THC, 1, 5, or 20 mg/kg) during gestation and lactation. Maternal exposure to low doses of THC (1 and 5 mg/kg), relevant for human consumption, resulted in an increased response to the reinforcing effects of a moderate dose of morphine (350 microg/kg), as measured in the place-preference conditioning paradigm (CPP) in the adult male offspring. These animals also displayed an enhanced exploratory behavior in the defensive withdrawal test. However, only females born from mothers exposed to THC 1 mg/kg exhibited a small increment in the place conditioning induced by morphine. The possible implication of the hypothalamo-pituitary-adrenal axis (HPA) was analyzed by monitoring plasma levels of adrenocorticotropic hormone (ACTH) and corticosterone in basal and moderate-stress conditions (after the end of the CPP test). Female offspring perinatally exposed to THC (1 or 5 mg/kg) displayed high basal levels of corticosterone and a blunted adrenal response to the HPA-activating effects of the CPP test. However, male offspring born from mothers exposed to THC (1 or 5 mg/kg) displayed the opposite pattern: normal to low basal levels of corticosterone, and a sharp adrenal response to the CPP challenge. The present study reveals that maternal exposure to low doses of THC results in an increased sensitivity to the reinforcing effects of morphine in the adult male offspring, and in sexually dimorphic behavioral and endocrine alterations in the adaptative responses to stressors such as novelty or place-preference testing. These results support the growing evidence of the importance of monitoring the long-term consequences of maternal consumption of cannabis derivatives.

Abstract
The association of narcolepsy with HLA class I antigens and HLA class II alleles was studies in a series of Spanish narcoleptic patients. The haplotype DRB1*1501-DRB5*0101-DQA1*0102-DQB1*0602 was found to be significantly associated with the disease, while the haplotype DRB1*0701-DRB4*01-DQA1*0201-DQB1*02 might confer a slight protective effect against narcolepsy. Gene dose-effect was not seen in any of the involved alleles, and linkage disequilibrium between the positively associated alleles was found to be stronger in patients than in controls. Statistical analysis applied to identify the HLA allele truly responsible for the association did not clearly discriminate between the contribution of DRB1*1501 and that of DQB1*0602, but it proved that the association with DQA1*0102 is secondary to that with DRB1*1501/DQB1*0602. Analysis of the diagnostic value of typing for the narcolepsy-associated alleles demonstrated a very high negative predictive value and revealed that this test can be convenient for exclusion of narcolepsy in cases when the diagnosis is not evident after clinical evaluation and the marker haplotype is absent. Finally, a family study indicated that narcolepsy is a multifactorial disorder that involves HLA genes under an incomplete penetrance model, with possible influences from environmental factors or other genes different to HLA genes.

Abstract
The narcolepsy-cataplexy syndrome is a disorder of unknown aetiology, characterized by excessive daytime sleepiness associated with cataplexy and other REM sleep phenomena. Diagnosis is based on the clinical findings, although this may be difficult especially with respect to confirming the cataplexy. Objective tests, such as typing for HLA, DR2DQ1 (DRw15DQw6, WHO90) and above all TMLS (average latency < 5 mn and two or more onsets of sleep in the phases REM and SOREMP's) is of great help. However, the exact diagnostic significance of some aspects of these tests and their parameters is still under discussion. In this paper we review our series of cases consisting of fourteen patients who fulfil the clinical diagnostic criteria required in the ICSD-1990. TMLS and HLA typing was done for all. Of the HLA types, DQ1 was present in all our patients, unlike DR2 which was not found in two patients. Regarding TMLS, the average latency < 5 mn is a parameter met by all cases, although one did not have SOREMP's. The findings of the objective tests done on our patients are in agreement with those described by other authors. They underline the significance of the support they lend to the diagnosis. However, they are not the definite answer to the problem.

Abstract
The presence of PLED or localized or lateralized periodic activity in encephalitis strongly suggests that the encephalitis is due to the herpes simplex virus. Nevertheless, there has been controversy over its clinical significance. In addition, since the introduction of antiviral drugs in the treatment of herpes encephalitis in its initial stages, the prognosis of the disease has improved. We studied nine patients all diagnosed as having herpes encephalitis and treated with acyclovir. The presence or absence of periodic activity and its characteristics were analyzed. It was seen that either there was no such activity, or if there was, it was not exactly as classically described.

Abstract
The present study evaluated the modulatory role of central corticotropin-releasing factor (CRF) systems in the mediation of the effects of acute exposure to the brain cannabinoid receptor agonist HU-210 [3-(1,1-dimethylheptyl)-(-)-11-hydroxy-delta 8-tetrahydrocannabinol] on defensive withdrawal behavior in male rats. The apparatus used for the defensive withdrawal test consisted of a small chamber, set on one side of a one-square meter open field. The actions of the potent CRF antagonist [D-Phe12,Nle21,38,C alpha MeLeu37]CRF (D-Phe CRF12-41) were examined on defensive behavior under both novel and familiar conditions. The acute i.c.v. administration of D-Phe CRF12-41 (0.2-5 micrograms/injection) antagonized the defensive behavior response to stressing conditions such as novelty or swim stress in field-habituated animals. The acute i.p. administration of HU-210 (4, 20 and 100 micrograms/kg) produced a clear dose-dependent stress-like effects in field-habituated animals, as reflected in the HU-210-induced increase in both the emergence latency and the mean time spent in the small chamber. The i.c.v. administration of 5 micrograms of D-Phe CRF12-41, 5 min before the administration of the cannabinoid prevented the stressing actions of HU-210 (20 micrograms/kg, but not 100 micrograms/kg). Acute administration of HU-210 also induced a dose-dependent increase in plasma corticosterone levels which was not antagonized by pretreatment with 5 micrograms of D-Phe CRF12-41. The present study suggests a role of central CRF systems in the mediation of the anxiogenic effects of brain cannabinoid receptor agonists. This finding is consistent with a direct hypothalamic effect of cannabinoids on the activation of the pituitary-adrenal axis.

Abstract
Cannabis sativa preparations (hashish, marijuana) are the most widely used illicit drugs during pregnancy in Western countries. The possible long-term consequences for the child of in utero exposure to cannabis derivatives are still poorly understood. Animal models of perinatal cannabinoid exposure provide a useful tool for examining the developmental effects of cannabinoids. Behavioral consequences of maternal exposure to either cannabis preparations or to its main psychoactive component, delta 9-tetrahydrocannabinol (THC) in rat models are reviewed in this paper. Maternal exposure to cannabinoids resulted in alteration in the pattern of ontogeny of spontaneous locomotor and exploratory behavior in the offspring. Adult animals exposed during gestational and lactational periods exhibited persistent alterations in the behavioral response to novelty, social interactions, sexual orientation and sexual behavior. They also showed a lack of habituation and reactivity to different illumination conditions. Adult offspring of both sexes also displayed a characteristic increase in spontaneous and water-induced grooming behavior. Some of the effects were dependent on the sex of the animals being studied, and the dose of cannabinoid administered to the mother during gestational and lactational periods. Maternal exposure to low doses of THC sensitized the adult offspring of both sexes to the reinforcing effects of morphine, as measured in a conditioned place preference paradigm. The existence of sexual dimorphisms on the developmental effects of cannabinoids, the role of sex steroids, glucocorticoids, and pituitary hormones, the possible participation of cortical projecting monoaminergic systems, and the mediation of the recently described cannabinoid receptors are also analyzed. The information obtained in animal studies is compared to the few data available on the long-term behavioral and cognitive effects on in utero exposure to cannabis in humans.

Abstract
DNA probes specific for genes coding for the heat stable enterotoxins (ST-I and ST-II), the heat labile enterotoxins (LT-I and LT-II), Shiga like cytotoxins and for the enterohemorrhagic factor (EHF), were used to examined 150 fecal Escherichia coli isolates from both diarrheic and healthy piglets. Thirty seven percent of the isolates hybridized with the LT-I probe, seventy one of them did so with the LT-II probe, while seventy six percent of the isolates possessed genes coding for the heat stable enterotoxins. No SLT-I positive hybridization was found and four percent of the isolates possessed SLT-II genes.

Abstract
This work evaluated motor behaviors in adult male and female rats exposed to delta 9-tetrahydrocannabinol (THC, 5 mg/kg) during gestation and lactation. The possibility that perinatal THC exposure induces sensitization to other drugs of abuse has also been addressed by evaluating morphine place preference conditioning (MPP) in the adult offspring. Maternal exposure to THC resulted in long-term effects on motor behaviors such as rearing, grooming and sniffing, in the adult offsprings of both sexes. Additionally, female offspring exposed to THC showed greater locomotor activity than controls, when measured using an actimeter. THC-exposed males exhibited an increased exploratory behavior in a plus-maze paradigm. When the adult animals were tested for MPP, THC-exposed offspring of both sexes exhibited an enhanced sensitivity to the rewarding effects of a moderate dose of morphine (350 micrograms/kg), an effect which was more marked in the males. These results showed that perinatal exposure to this psychoactive cannabinoid affected motor behaviors in the adult, suggesting a psychomotor activation very similar to that observed after gestational exposure to other drugs of abuse. A possible role of a THC-induced hypothalamus-pituitary-adrenal (HPA) axis activation was also evaluated in the present study. THC-exposed females exhibited higher levels of both corticotropin releasing factor (CRF-41) in the medial basal hypothalamus (MBH) and plasma corticosterone, whereas THC-exposed males showed the lower levels of both endocrine parameters. Since glucocorticoids are important modulators of both brain development, and adult brain function, these results indicate a possible role of HPA axis disturbances in the mediation of the behavioral effects described after perinatal THC exposure.

Abstract
An experimental fattening period was performed with 36 pigs in order to evaluate the safety and efficacy of a bivalent adjuvanted Serpulina hyodysenteriae bacterin. The pigs originated from three different farms and were split into six groups. Eighteen pigs were vaccinated twice, two weeks apart and the rest served as controls. One unvaccinated pig in each group was inoculated intragastrically with 4 x 10(8) active S. hyodysenteriae spirochaetes, B 78 strain. Weight evolution, clinical symptoms, shedding of S. hyodysenteriae and serum antibody titres were monitored for 12 weeks in all pigs. The severity of clinical symptoms and shedding of spirochaetes in faeces were significantly reduced in vaccinated pigs as compared to controls. Statistically significant differences in weight gain between vaccinates and controls were detected coinciding with the maximum shedding of S. hyodysenteriae in faeces. All vaccinated pigs seroconverted, as measured by indirect ELISA, and had a good anamnestic response after the second vaccine dose. The bacterin proved to be useful for both the reduction of clinical symptoms and the number of infected animals in a fattening unit. Adverse post-vaccinal reactions were not observed in any pig.

Abstract
We carried out a cross-sectional study to assess morphological findings and incidence of complications in 77 inferior vena cava filters (IVC) implanted in 75 patients between April 1990 and January 1994. Follow-up ranged from 3 to 61 months (mean, 38.5 months) and was carried out by telephone interview, clinical examination, X-rays of the ilium/vena cavum and, in some cases, by Doppler sonogram and computed tomography. Findings revealed IVC thrombosis in 38% of patients, edema in the lower extremities in 63.4%, angling > 15 degrees in 8 patients, defective opening in 4, fibrosis of the vena cava with stenosis in 2 and perforation of the IVC in 3. Although our study shows that the incidence of IVC thrombosis after implantation of filters is higher than suspected, its clinical importance is slight.

Abstract
Disturbances of sleep are frequent and varied in patients with Parkinson's disease. In an attempt to find out about these disturbances, we carried out interviews using the Vanna and Mazzuia questionnaire, modified for forty-five sufferers of Parkinson's disease, and forty healthy adults. We researched sleep habits and disturbances, as well as the consumption of hypnotics. We found that both groups had similar habits, although those with PD altered according to the stage of development of the disease, thus difficulty in staying sleep and parasomnia were more frequent in PD sufferers and worsened in the most advanced cases. On the other hand the quality of night sleep and the consumption of hypnotics interfered in the daytime efficiency of those suffering from Parkinson's Disease.

Abstract
The present study investigated the effects of systemic administration of the putative dopamine D3 receptor agonist 7-hydroxy-N,N-di-n-propyl-2-aminotetralin (7-OH-DPAT) on the acquisition and expression of morphine-induced place preference in male Wistar rats. Using a a 3-day schedule of conditioning it was found that 7-OH-DPAT in a broad dose range (0.01, 0.25 and 5.0 mg/kg) did not produce significant place preference. However, the administration of either 0.25 or 5.0 mg/kg of 7-OH-DPAT 15 min prior to the exposure to morphine (1 mg/kg) prevented the acquisition of a morphine place preference, whereas the 0.01 mg/kg dose of the dopamine receptor agonist was uneffective. In addition, when 7-OH-DPAT was acutely administered 15 min prior to the testing session of an already established morphine place preference, the 0.01 mg/kg dose prevented the expression of this conditioned response. This effect was not observed with either 0.25 and 5.0 mg/kg doses of this dopamine D3 receptor agonist. It was suggested that the different dose related effects of 7-OH-DPAT on the acquisition and expression of morphine place preference might be related to the intrinsic ability of this agonist for interacting with pre- and postsynaptic dopamine D3 receptors located in limbic projecting areas of the mesencephalic dopamine system, although involvement of dopamine D2 receptors cannot be excluded. The pattern of effects seen with 7-OH-DPAT suggests that it may be useful for treating opiate dependence and craving.
