Abstract
In plant ecology, the terms growth and development are often used interchangeably. Yet these constitute two distinct processes. Plant architectural traits (e.g. number of successive forks) can estimate development stages. Here, we show the importance of including the effect of development stages to better understand size-related trait scaling relationships (i.e. between height and stem diameter). We focused on one common savanna woody species (Senegalia nigrescens) from the Greater Kruger Area, South Africa. We sampled 406 individuals that experience different exposure to herbivory, from which we collected four traits: plant height, basal stem diameter, number of successive forks (proxy for development stage), and resprouting. We analysed trait relationships (using standardized major axis regression) between height and stem diameter, accounting for the effect of ontogeny, exposure to herbivory, and resprouting. The number of successive forks affects the scaling relationship between height and stem diameter, with the slope and strength of the relationship declining in more developed individuals. Herbivory exposure and resprouting do not affect the overall height-diameter relationship. However, when height and stem diameter were regressed separately against number of successive forks, herbivory exposure and resprouting had an effect. For example, resprouting individuals allocate more biomass to both primary and secondary growth than non-resprouting plants in more disturbed conditions. We stress the need to include traits related to ontogeny so as to disentangle the effect of biomass allocation to primary and secondary growth from that of development in plant functional relationships.

Abstract
For gas chromatography - mass spectrometry (GC-MS) analyses performed in situ, pH and salts (e.g., chlorides, sulfates) may enhance or inhibit the detection of targeted molecules of interest for astrobiology (e.g. amino acids, fatty acids, nucleobases). Obviously, salts influence the ionic strength of the solutions, the pH value, and the salting effect. But the presence of salts may also produce complexes or mask ions in the sample (masking effect on hydroxide ion, ammonia, etc.). For future space missions, wet chemistry will be conducted before GC-MS analyses to detect the full organic content of a sample. The defined organic targets for space GC-MS instrument requirements are generally strongly polar or refractory organic compounds, such as amino acids playing a role in the protein production and metabolism regulations for life on Earth, nucleobases essential for DNA and RNA formation and mutation, and fatty acids that composed most of the eukaryote and prokaryote membranes on Earth and resist to environmental stress long enough to still be observed on Mars or ocean worlds in geological well-preserved records. The wet-chemistry chemical treatment consists of reacting an organic reagent with the sample to extract and volatilize polar or refractory organic molecules (i.e. dimethylformamide dimethyl acetal (DMF-DMA) in this study). DMF-DMA derivatizes functional groups with labile H in organics, without modifying their chiral conformation. The influence of pH and salt concentration of extraterrestrial materials on the DMF-DMA derivatization remains understudied. In this research, we studied the influence of different salts and pHs on the derivatization of organic molecules of astrobiological interest with DMF-DMA, such as amino acids, carboxylic acids, and nucleobases. Results show that salts and pH influence the derivatization yield, and that their effect depend on the nature of the organics and the salts studied. Second, monovalent salts lead to a higher or similar organic recovery compared to divalent salts regardless of pH below 8. However, a pH above 8 inhibits the DMF-DMA derivatization influencing the carboxylic acid function to become an anionic group without labile H. Overall, considering the negative effect of the salts on the detection of organic molecules, future space missions may have to consider a desalting step prior to derivatization and GC-MS analyses.

Abstract
AIM Crohn's anal fistula (CAF) is a complex condition, with no agreement on which patient characteristics should be routinely reported in studies. The aim of this study was to develop a core descriptor set of key patient characteristics for reporting in all CAF research. METHOD Candidate descriptors were generated from published literature and stakeholder suggestions. Colorectal surgeons, gastroenterologists and specialist nurses in inflammatory bowel disease took part in three rounds of an international modified Delphi process using nine-point Likert scales to rank the importance of descriptors. Feedback was provided between rounds to allow refinement of the next ratings. Patterns in descriptor voting were assessed using principal component analysis (PCA). Resulting PCA groups were used to organize items in rounds two and three. Consensus descriptors were submitted to a patient panel for feedback. Items meeting predetermined thresholds were included in the final set and ratified at the consensus meeting. RESULTS One hundred and thirty three respondents from 22 countries completed round one, of whom 67.0% completed round three. Ninety seven descriptors were rated across three rounds in 11 PCA-based groups. Forty descriptors were shortlisted. The consensus meeting ratified a core descriptor set of 37 descriptors within six domains: fistula anatomy, current disease activity and phenotype, risk factors, medical interventions for CAF, surgical interventions for CAF, and patient symptoms and impact on quality of life. CONCLUSION The core descriptor set proposed for all future CAF research reflects characteristics important to gastroenterologists and surgeons. This might aid transparent reporting in future studies.

Abstract
Background The aim of the present study was to describe in detail an approach to proctectomy in ulcerative colitis (UC), which can be standardized; near-total mesorectal excision (near-TME), to prevent injuries to autonomic pelvic nerves and subsequent sexual dysfunction. Methods We demonstrate the technique ex vivo on a cadaver from a male patient in lithotomy position and on a sagittal section of a male pelvis. We also demonstrate the technique in vivo in two male patients diagnosed with UC, with no history of sexual dysfunction or bowel neoplasia. The study was performed at the Human Embryology and Anatomy Department. University of Valencia, Spain. Results The posterolateral dissection during a near-TME is similar to that of an oncologic TME, whereas the anterolateral is similar to that of a close rectal dissection. The near-TME technique preserves the superior hypogastric plexus, the hypogastric nerves, the nervi erigentes, the inferior hypogastric plexus, the pelvic plexus and the cavernous nerves. Conclusion The near-TME technique is the standardisation of the technique for proctectomy in male patients with ulcerative colitis. Near-TME requires experience in pelvic surgery and an exhaustive knowledge of the embryological development and of the surgical anatomy of the pelvis.

Abstract
BACKGROUND There is a lack of information regarding the provision of parental leave for surgical careers. This survey study aims to evaluate the experience of maternity/paternity leave and views on work-life balance globally. METHODS A 55-item online survey in 24 languages was distributed via social media as per CHERRIES guideline from February to March 2020. It explored parental leave entitlements, attitude towards leave taking, financial impact, time spent with children and compatibility of parenthood with surgical career. RESULTS Of the 1393 (male : female, 514 : 829) respondents from 65 countries, there were 479 medical students, 349 surgical trainees and 513 consultants. Consultants had less than the recommended duration of maternity leave (43.8 versus 29.1 per cent), no paid maternity (8.3 versus 3.2 per cent) or paternity leave (19.3 versus 11.0 per cent) compared with trainees. Females were less likely to have children than males (36.8 versus 45.6 per cent, P = 0.010) and were more often told surgery is incompatible with parenthood (80.2 versus 59.5 per cent, P < 0.001). Males spent less than 20 per cent of their salary on childcare and fewer than 30 hours/week with their children. More than half (59.2 per cent) of medical students did not believe a surgical career allowed work-life balance. CONCLUSION Surgeons across the globe had inadequate parental leave. Significant gender disparity was seen in multiple aspects.

Abstract
BACKGROUND AND AIMS We aimed to study subclinical non-invasive vascular markers as predictors of incident long-term cognitive impairment in a longitudinal population-based study. METHODS The Barcelona-Asymptomatic Intracranial Atherosclerosis (AsIA) study is a population-based study that included a random sample of 933 Caucasian subjects (mean age 66 years, 64% male) with a moderate-high vascular risk and without history of stroke or dementia. Subclinical carotid and intracranial stenosis was assessed at baseline visit by cervical and transcranial color-coded duplex (TCCD) and confirmed by magnetic resonance angiography. Cervico-cerebral stenosis (CCS) was defined as the presence of extra and/or intracranial stenosis >50%. Baseline middle cerebral artery pulsatility index (MCA-PI) was measured bilaterally by TCCD, and mean PI of both sides was considered for analyses. Subjects were followed-up to determine incident long-term cognitive impairment (mild cognitive impairment or dementia). RESULTS After a median of 7.16 [6.91-7.75] years of follow-up, 91 subjects (9.7%) developed cognitive impairment, 27 of them mild cognitive impairment, and 64 dementia. Incidence of cognitive impairment was significantly higher among subjects with subclinical CCS (21.4% versus 9% in those without CCS) and among those with mean MCA-PI>1 (13.5% versus 7.4% in those with MCA-PI<1). In multivariate Cox regression analyses, both CCS and MCA-PI>1 were independently associated with incident cognitive impairment with HR of 2.07 [1.11-3.88] and 1.58 [1.02-2.46], respectively. CONCLUSIONS Subclinical cervico-cerebral stenosis and higher MCA-PI are non-invasive neurosonological markers of incident long-term cognitive impairment in our population.

Abstract
PURPOSE To determine the reliability and validity of clinical tests to assess posture, pain location, and cervical spine mobility in adults with grades I-IV neck pain and associated disorders (NAD). METHODS We systematically searched electronic databases to update the systematic review of the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders. Eligible reliability and validity studies were critically appraised using modified versions of the QAREL and QUADAS-2 instruments, respectively. Evidence from low risk of bias studies were synthesized following best evidence synthesis principles. RESULTS We screened 14302 articles, critically appraised 46 studies, and found 32 low risk of bias articles (14 reliability and 18 validity studies). We found preliminary evidence of: 1) reliability of visual inspection, aided with devices (CROM and digital caliper) to assess head posture; 2) reliability and validity of soft tissue palpation to locate tender/trigger points in muscles; 3) reliability and validity of joint motion palpation to assess stiffness and pain provocation in combination; and 4) range of motion tests using visual estimation (in cervical extension only) or devices (digital caliper, goniometer, inclinometer) to assess cervical mobility. CONCLUSIONS We found little evidence to support the reliability and validity of clinical tests to assess head posture, pain location and cervical mobility in adults with NAD grades I-III. More advanced validity studies are needed to inform the clinical utility of tests used to evaluate patients with NAD.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor, with the Milan criteria considered to be the gold standard for patient selection for liver transplantation (LT). MATERIALS AND METHODS We performed a descriptive observational study, reviewing 20 years of experience of LT in patients with HCC in the Fundacion Valle del Lilí in Cali, Colombia. Subgroup analysis was undertaken for periods 1999 to 2007 and 2008 to 2015. RESULTS Fifty-seven cases with a pretransplant HCC diagnosis were reviewed. In the first period patients within the Milan criteria had a recurrence-free survival at 5 years of 66.6%, and in those who exceeded the Milan criteria, recurrence-free survival was 75%. In the second period, patients within the Milan criteria, recurrence-free survival at 5 years was 93.5%, and in those who exceeded the Milan criteria, recurrence-free survival was 75.7%. No statistically significant difference was found in either period. For patients with mild and moderate tumor differentiation, the relapse survival rate at 5 years was 69.4% (95% confidence interval [CI] 35.8-87.8) and 74.7% (95% CI 44.5-90), respectively. All patients with poor tumor differentiation relapsed and died within 3 years. CONCLUSION Global and recurrence-free survival among patients who met and patients who exceeded the Milan criteria was not significantly different, suggesting an expansion of the Milan criteria to include potential recipients who were previously excluded. Obtaining histologic differentiation and identifying vascular invasion will provide a more worthwhile contribution to LT decision making.

Abstract
AIM There has been controversy about the presentation and treatment of acute colonic diverticulitis (AD) in young patients. The aim of this observational study was to evaluate the virulence and natural history of AD in three different age groups of patients. METHOD The study was performed on 686 patients with the diagnosis of a first episode of AD admitted between January 1998 and December 2008. Patients were classified into three groups: age 45 years or younger (group 1), 45-70 years of age (group 2) and 70 years or more (group 3). The variables studied were gender, American Society of Anesthesiologists status, associated comorbidity, type of treatment, length of hospital stay and recurrence of AD. RESULTS Group 1 included 99 (14.4%) patients, group 2 339 (49.4%) and group 3 248 (36.2%). Of these, 144 patients needed emergency operation at the first admission, 25 underwent elective surgery after the first episode of AD and 10 died after medical treatment; 507 patients were followed for recurrence. In all, 104 (20.5%) patients had a recurrence of AD that required hospitalization. Fifty (9.9%) presented with one episode of severe recurrence, without any difference between the groups (P = 0.533). There were no differences in the analysis of cumulative recurrence (Kaplan-Maier) between the three groups. CONCLUSION AD does not present a more aggressive clinical course in younger patients and it can be safely managed using the same strategy as in middle aged and older patients.

Abstract
AIM This paper addresses the current status of the treatment of acute colonic diverticulitis by an evidence-based review. METHOD A systematic search in PUBMED, MEDLINE, EMBASE and Google scholar on colonic diverticulitis was performed. Diagnostic tools, randomized controlled trials, non-randomized comparative studies, observational epidemiological studies, national and international guidelines, reviews of observational studies on elective and emergency surgical treatment of diverticulitis, and studies of prognostic significance were reviewed. Criteria for eligibility of the studies were diagnosis and classification, medical treatment, inpatients and outpatients, diverticulitis in young patients, immunosuppression, recurrence, elective resection, emergency surgery, and predictive factors. RESULTS Some 92 publications were selected for comprehensive review. The review highlighted that computed tomography is the most effective test in the diagnosis and staging of acute diverticulitis; outpatient treatment can be performed for uncomplicated diverticulitis in patients without associated comorbidities; conservative treatment is aimed at those patients with uncomplicated acute diverticulitis; elective surgery must be done on an individual basis; laparoscopic approach for elective treatment of diverticulitis is appropriate but may be technically complex; in perforated diverticulitis, resection with primary anastomosis is a safe procedure that requires experience and should take into account strict exclusion criteria. CONCLUSION The heterogeneity of patients with colonic diverticular disease means that both elective and urgent treatment should be tailored on an individual basis.

Abstract
AIM To study any possible differences in morbidity, mortality and overall survival rate after curative surgery for obstructive colon cancer according to tumour location. METHOD From January 1994 to December 2006, patients with colonic cancer presenting as obstruction were analysed. The two groups were defined as proximal and distal according to the tumour location with respect to the splenic flexure. In relation to the surgeon specialization, patients were operated on by a colorectal surgeon and by a general surgeon. Postoperative morbidity and mortality and cancer-related survival at 3 years were analysed. RESULTS Of the 377 patients included in the study, there were 173 patients (45.9%) in the proximal group and 204 patients (54.1%) in the distal group. The global morbidity was 54.9% without differences in postoperative morbidity except for anastomotic leakage, which was higher in the proximal group (P < 0.014). No differences in postoperative mortality were observed. After patients were stratified by the tumour node metastasis system, the differences between the groups, with respect to 3-year overall survival, cancer-related survival and probability of being free from recurrence, did not reach statistical significance. The overall survival after radical surgery for colonic obstruction was 57.6%. CONCLUSION Mortality and morbidity after emergency surgery for obstructing colon cancer are high. Specialization in colorectal surgery influences postoperative results in terms of lower anastomotic dehiscence rate after emergency proximal colon resection. After radical surgery, tumour location does not appear to influence the prognosis of obstructive colon cancer.

Abstract
A gallbladder incarcerated hernia associated with Mirizzi syndrome is a very rare entity and to our knowledge this is the first case ever described in literature. An 85-year-old man presented at the emergency department with a tender right upper quadrant mass. Computed Tomography (CT) revealed the presence of a gallbladder lithiasis with signs of acute cholecystitis, herniated through the abdominal wall with an associated Mirizzi syndrome. Laparoscopic cholecystectomy and repair of the abdominal wall defect were performed. The patient recovered very well and the postoperative period was uneventful.

Abstract
IntroductionOne of the problems of many studies and clinical trials is that don’t reflect the patient's opinion about the medication that they receive and their satisfaction.Objetive and aimsThe aim of this study was to assess the degree of outpatients satisfaction with antipsychotic treatment in four outpatients clinics in Mallorca. The adherence rates was estimated from information provided by the patients and their psychiatrists.MethodsA cross.-sectional and descriptive study was conducted during one month, from May to June 2010, by administering several questionnaires to outpatients with psychotic disorders. It was designed a case report data which recorded the following variables: age, gender, diagnosis (schizophreniform, schizophrenia, schizoaffective disorder, delusional, psychotic disorder not otherwise specified), time since diagnosis, substance use, number of antipsychotic drugs, type of antipsychotic (oral and / or im), number of doses per day and number of tablets, via of administration (buttocks or deltoid). The psychometric instruments used were: the Morisky-Green test, Haynes-Sacket test, the MSQ (Medication Satisfaction Questionnaire) and CGI (Clinical Global Impression).ResultsThe sample was of 92 patients with a mean age of 42.1 years (SD 12.2): 57.6% male and the most frequent diagnosis was schizophrenia in 65.2%. The duration of treatment from diagnosis was more than 5 years in 66.3%.ConclusionsThe patients on maintenance monotherapy with RLAI showed better adherence rates and more insight, evaluated by their psychiatrits.78% of patients receiving antipsychotic medication injections were satisfied with the treatment.Patients with RLAI administrating in deltoid were satisfied in 65.7%.

Abstract
BACKGROUND Tumour necrosis factor-blockade with infliximab has advanced the treatment of Crohn's disease. While infliximab is efficacious, it remains to be determined whether patients who enter clinical remission with an anti-tumour necrosis factor therapy can have their treatment stopped and retain the state of remission. AIM To assess in patients with Crohn's disease who obtained infliximab-induced remission, the proportion who relapsed after infliximab discontinuation. METHODS This longitudinal cohort study examined patients from a University-based IBD referral centre. Forty eight patients with Crohn's disease in full clinical remission and who then discontinued infliximab were followed up for up to 7 years. Crohn's disease relapse was defined as an intervention with Crohn's disease medication or surgery. RESULTS Kaplan-Meier analysis of the proportion of patients with sustained clinical benefit demonstrated that 50% relapsed within 477 days after infliximab discontinuance. In contrast, 35% of patients remained well, and without clinical relapse, up to the end of the nearly 7-year follow-up. CONCLUSIONS In patients with Crohn's disease with an infliximab-induced remission, stopping infliximab results in a predictable relapse in a majority of patients. Nevertheless, a small percentage of patients sustain a long-term remission.

Abstract
A coal tar pitch was fractionated by solvent solubility into heptane-solubles, heptane-insoluble/toluene-solubles (asphaltenes), and toluene-insolubles (preasphaltenes). The aim of the work was to compare the mass ranges of the different fractions by several different techniques. Thermogravimetric analysis, size-exclusion chromatography (SEC) and UV-fluorescence spectroscopy showed distinct differences between the three fractions in terms of volatility, molecular size ranges and the aromatic chromophore sizes present. The mass spectrometric methods used were gas chromatography/mass spectrometry (GC/MS), pyrolysis/GC/MS, electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FTICRMS) and laser desorption time-of-flight mass spectrometry (LD-TOFMS). The first three techniques gave good mass spectra only for the heptane-soluble fraction. Only LDMS gave signals from the toluene-insolubles, indicating that the molecules were too involatile for GC and too complex to pyrolyze into small molecules during pyrolysis/GC/MS. ESI-FTICRMS gave no signal for toluene-insolubles probably because the fraction was insoluble in the methanol or acetonitrile, water and formic acid mixture used as solvent to the ESI source. LDMS was able to generate ions from each of the fractions. Fractionation of complex samples is necessary to separate smaller molecules to allow the use of higher laser fluences for the larger molecules and suppress the formation of ionized molecular clusters. The upper mass limit of the pitch was determined as between 5000 and 10,000 u. The pitch asphaltenes showed a peak of maximum intensity in the LDMS spectra at around m/z 400, in broad agreement with the estimate from SEC. The mass ranges of the toluene-insoluble fraction found by LDMS and SEC (400-10,000 u with maximum intensity around 2000 u by LDMS and 100-9320 u with maximum intensity around 740 u by SEC) are higher than those for the asphaltene fraction (200-4000 u with maximum intensity around 400 u by LDMS and 100-2680 u with maximum intensity around 286 u by SEC) and greater than values considered appropriate for petroleum asphaltenes (300-1200 u with maximum intensity near 700 u).

Abstract
PURPOSE Portal vein thrombi have been observed after restorative proctocolectomy and ileal pouch-anal anastomosis, and present as a clinical spectrum of abdominal pain, fever, and leukocytosis. Anticoagulation treatment is usually associated with resolution of symptoms. However, the long-term consequences and effect on pouch function are not known. The purpose of this study was to analyze the long-term functional outcome of patients with confirmed portal vein thrombi after restorative proctocolectomy. METHODS A retrospective study of all patients undergoing restorative proctocolectomy from January 1997 to 2000 was performed. A case-control study was designed that matched 37 patients with confirmed portal vein thrombi in this period with 133 patients without portal vein thrombi; the groups were compared with respect to pouch function and quality of life by using the Global Cleveland Clinic Quality of Life Questionnaire for pelvic pouch patients. RESULTS The mean follow-up was 4.73 (range, 4.21-7.28) years. The percentage of male patients was 58.8. The most common diagnosis was ulcerative colitis (62.4 percent). There were no significant differences between portal vein thrombi patients and controls with respect to pouch function (number of bowel movements, urgency, incontinence), episodes of pouchitis, or quality of life. CONCLUSIONS Portal vein thrombi can be a serious complication after restorative proctocolectomy that usually resolves with anticoagulation therapy. Long-term pouch function and quality of life are not affected.

Abstract
OBJECTIVE Intersphincteric abscesses are relatively rare, and in some cases of upward extensions in the supralevator plane, can be difficult to manage. The aim of this study was to analyse the type of treatment used in these abscesses. METHODS Twenty-one intersphincteric abscesses treated by endoanal drainage in our colorectal unit between 1992 and 2004 were reviewed from our database; location and extension of the abscess, type of treatment and recurrence rates and the use of endoanal ultrasound were studied. RESULTS Ninety per cent of patients were male; 10 had a previous history of surgery for perianal abscess and suppuration (48%); 16 (76%) had a posterior location and five were anterolateral. Twelve patients had low intersphincteric abscesses and were treated by laying open the abscess and dividing the internal sphincter. Nine were found to have high extensions into the intermuscular planes and were treated by staged procedures: a temporary transanal mushroom catheter was used in seven patients. Endoanal ultrasound was used initially in seven patients (33.3%) and for the evaluation of definitive treatment in 11 (52%). CONCLUSIONS Low intersphincteric abscesses should be treated by de-roofing of the abscess and division of the internal sphincter up to a level of the dentate line. High intersphincteric abscesses are relatively frequent and mostly require staged surgery with a temporary mushroom (de Pezzer) catheter. Accurate anatomical ultrasound localization and proper drainage become important to avoid recurrences or extrasphincteric fistulas.

Abstract
The partial contribution of polycyclic aromatic hydrocarbons (PAH), capable of being detected by gas chromatography (GC-PAH), both to the total mass of the extractable organic fraction of flame-formed carbon particulates and to its UV-visible absorption and fluorescence spectra, has been determined by previous work. This contribution indicates the presence of PAH of molecular weight (MW) greater than 400 Da not accessible to conventional analysis. The detection of species in this higher MW range is important for both their potential toxicology and their possible role in soot formation. In the present work extracts of soots have been analyzed by linear mode laser desorption/ionization time-of-flight mass spectrometry (LDI-TOF-MS) to extend the MW range that can be analyzed beyond the GC-PAH. The results have been compared with both analysis by reflector mode LDI-TOF-MS and the MW evaluation obtained by SEC analysis, as the shortcomings and advantages of both techniques appear to be complementary. Matching the results from the two techniques could give interesting insights in the molecular mass range between GC-PAH and the first soot particles (of mass > 2000 Da). Mass spectra in this molecular mass range have been obtained with a main ion sequence spacing of 24 Th and a minor ion sequence also with a spacing of 24 Th but off-set by 12 Th with respect to the main sequence. The two ion progressions have been interpreted by attributing the predominant peaks mainly to PAH with even-carbon numbers and the smaller ones to cyclopenta-fused ring PAH. These distributions indicate the occurrence of two competitive mechanisms in the growth of PAH and soot nucleation, i.e. the addition of acetylene (HACA mechanism) and the incorporation of pentagons by large polycyclic aromatic molecules into their aromatic bonding network.

Abstract
BACKGROUND Condyloma acuminata is the most common anorectal lesion in patients infected with human immunodeficiency virus (HIV). Surgical treatment can be challenging in cases where the size and extension into the anal canal make individual excision impossible. These patients require large resections and reconstruction using grafts or local flaps. METHODS Six patients were treated for giant perianal condylomas between 1999 and 2001. Four patients were HIV-positive, and were selected for surgical intervention after achieving a T4 count >350 and low viral replication. In 5 cases, the lesions were circularly resected up to the pectinate line and the defect was reconstructed using a bilateral V-Y plasty. In the remaining case, fulguration was possible on one side and a unilateral V-Y plasty was performed. RESULTS There were no infections or healing delays in this series, and the functional and aesthetic results are satisfactory. CONCLUSION V-Y plasties are a valid method for perianal reconstruction after resection of giant anal condyloma, with good results in selected patients with HIV infection.

Abstract
A series of new arylpiperazinomethyl derivatives was designed and studied as potential D4 ligands. The synthesis of these compounds required an original synthetic route. Some of the tested compounds were found to be as potent as clozapine at D4 receptors. Moreover, compounds which displayed a high D2/D4 selectivity ratio (>122) were selected for further pharmacological evaluation.

Abstract
A 25-year-old white woman was diagnosed with Crohn's disease involving the small and large intestines. She had a complex clinical course that required treatment with multiple pharmacological agents, including intravenous, oral and rectal corticosteroids. She also received parenteral nutrition with lipid emulsions. Finally, repeated intestinal resections and drainage of perianal abscesses were required. Her disease was complicated by gallstones, urolithiasis and hip pain. After osteonecrosis was diagnosed, joint replacements were performed. Review of the pathological sections from the resected hip, however, resulted in detection of granulomatous inflammation with multinucleated giant cells - the histological 'footprint' of Crohn's disease in the gastrointestinal tract. Because prior specialized perfusion fixation pathological studies of the intestine in Crohn's disease have shown that granulomas are located in the walls of blood vessels, a possible mechanism for the pathogenesis of osteonecrosis in Crohn's disease is chronic microvascular ischemia of bone.

Abstract
Inhaled acetaldehyde may induce bronchoconstriction in asthmatic subjects and provides a new method to investigate airway responsiveness. The objective of the study was to determine whether acetaldehyde was a more specific stimulus than methacholine in differentiating asthma from chronic bronchitis with or without airflow limitation. Bronchial provocation challenges with methacholine and acetaldehyde were performed in 62 asthmatics and in 59 smokers with chronic bronchitis (32 with chronic bronchitis alone and 27 with chronic bronchitis and coexisting chronic obstructive pulmonary disease (COPD)). The response to both bronchoconstrictor agents was measured by the provocative concentration required to produce a 20% fall in forced expiratory volume in one second (FEV1; PC20). The two types of challenge yielded a similarly high level of sensitivity (100% for methacholine and 92% for acetaldehyde) in revealing airway hyperresponsiveness in asthma. However, bronchoprovocation with acetaldehyde yielded considerably greater specificity (95%) than bronchoprovocation with methacholine (24%) in separating asthma from chronic bronchitis. In subjects with asthma, methacholine and acetaldehyde responsiveness were weakly but significantly correlated (r=0.42, p=0.001) but no correlation was found between airway responsiveness to acetaldehyde and baseline FEV1 (r=0.13, p=0.33). These findings suggest that the demonstration of bronchoconstriction in response to acetaldehyde may be a more specific test than methacholine in the differentiation of asthma from chronic bronchitis. Furthermore, methacholine and acetaldehyde hyperresponsiveness are not reflecting the same pathophysiological process in the airways.

Abstract
BACKGROUND Major, almost insurmountable, deterrents exist to the use of the small capacity, defunctionalized, nonneurogenic urinary bladder in renal transplantation, namely, the technical difficulty in performing a satisfactory ureteral implantation with conventional methods and the potential secondary problems with high grade ureteral reflux and obstruction. Alternatives are less than ideal and include transplantation into a bowel-augmented urinary bladder with intermittent self-catheterization, ileal conduit urinary diversion, or avoidance of transplantation and relegating the patient to life-long dialysis. METHODS Eight consecutive patients (ages 13 months to 29 years) with small, defunctionalized urinary bladders underwent a new method of intravesical implantation of the transplant ureter. The mean capacity of these bladders was 18.5+/-13.1 ml (range 6 to 45 ml), with the bladders defunctionalized for a mean 81.6+/-24.3% of the patients' total lifetime. The technique involved placement of the transplant ureter into a shallow, mucosa-denuded, rectangular trough extending from a superiorly placed ureteral hiatus distally to the trigone. We hypothesized that the mucosal margins on the two lateral aspects of the rectangular trough would grow over the anterior surface of the ureter until they met the advancing mucosal edges from the contralateral side to form a natural neosubmucosal tunnel. RESULTS Posttransplantation cystoscopic examination demonstrated bladder mucosal regeneration and growth over the ureter, confirming the spontaneous development of a good length neosubmucosal tunnel. All patients demonstrated no evidence of ureteral reflux or ureteral obstruction, whereas an immediate prior cohort of four consecutive patients with bladder capacities < or =30 ml showed that three of four had ureteral reflux (P=0.02) and four of four developed hydronephrosis (P=0.002). All urinary bladders in the present cohort enlarged to expected normal or nearnormal capacities. Serum creatinines were stable throughout the entire follow-up period, with the exception of one patient who had rejection episodes. Two patients had urinary tract infections posttransplantation, but there were no episodes of acute pyelonephritis. CONCLUSIONS This novel technique for ureteral implantation successfully capitalizes on the regenerative potential of the bladder mucosa, resulting in a physiological, anatomically natural, and very effective neosubmucosal tunnel. It appears to guarantee success against both ureteral reflux and obstruction, no matter how small the urinary bladder, and offers no hindrance to enlarging the bladder to near normal capacity posttransplantation. The implantation technique is simple and safe, and its use should eliminate the reluctance to use these bladders. Moreover, this procedure offers a major incentive for the successful rehabilitation of small, defunctionalized, nonneurogenic bladders after kidney transplantation.

Abstract
The in vitro activities of 3-hydroxy-imidazolidin-4-one derivatives demonstrated very restricted structure-activity relationships at the strychnine-insensitive glycine site of the NMDA receptor. The most active compound (3a) was completely unsubstituted and exhibited affinity and efficacy similar to that of D-cycloserine, the prototypical partial agonist at this site.

Abstract
OBJECTIVE To determine the prevalence of keratoconjunctivitis sicca and xerostomia related to Sjögren's syndrome (SS) in asymptomatic patients with diagnosed autoimmune thyroid diseases (AITD); and to investigate whether the immunopathologies of sialadenitis observed in AITD associated SS and primary SS are similar. METHODS One hundred seventy-six patients diagnosed with AITD (88 with Graves' disease, 40 Hashimoto's thyroiditis, 48 primary myxedema) were tested for keratoconjunctivitis sicca (Schirmer's test and rose bengal staining) and for xerostomia (salivary scintigraphy and labial salivary gland biopsy). Immunohistopathological studies were performed on cryostat sections of bucal mucosa biopsies using antibodies to CD3, CD4, CD8, CD20, CD14, CD25, LFA-1, ICAM-3 HLA class II, tumor necrosis factor-alpha, interleukin 1, and interferon-gamma. RESULTS Nineteen of 52 (37%) patients with AITD fulfilled the criteria for xerostomia and 39/170 (23%) for keratoconjunctivitis sicca. Features of SS were diagnosed in 43 of 176 (24%) patients with AITD, with similar prevalence in Graves' (20%). Hashimoto's thyroiditis (27%), and primary myxedema (29%). In AITD associated SS, infiltrating lymphocytes were mainly CD3+ T lymphocytes, with a CD4/CD8 ratio of 2:1. In most patients infiltrating lymphocytes expressed activation markers, HLA class II molecules, and interleukin 2 receptor (CD25). In some patients HLA class II was inappropriately expressed in the epithelial gland cells. CONCLUSION The finding that a third of patients with AITD have SS features confirms that AITD and SS are mutually associated. Together with the similarity of immunopathology of sialadenitis in AITD associated SS in primary SS, this supports the theory that SS and AITD are 2 autoimmune diseases closely related pathogenetically.

Abstract
Quiescent endothelial cells (EC) regulate blood flow and prevent intravascular thrombosis. This latter effect is mediated in a number of ways, including expression by EC of thrombomodulin and heparan sulfate, both of which are lost from the EC surface as part of the activation response to proinflammatory cytokines. Loss of these anticoagulant molecules potentiates the procoagulant properties of the injured vasculature. An additional thromboregulatory factor, ATP diphosphohydrolase (ATPDase; designated as EC 3.6.1.5) is also expressed by quiescent EC, and has the capacity to degrade the extracellular inflammatory mediators ATP and ADP to AMP, thereby inhibiting platelet activation and modulating vascular thrombosis. We describe here that the antithrombotic effects of the ATPDase, like heparan sulfate and thrombomodulin, are lost after EC activation, both in vitro and in vivo. Because platelet activation and aggregation are important components of the hemostatic changes that accompany inflammatory diseases, we suggest that the loss of vascular ATPDase may be crucial for the progression of vascular injury.

Abstract
The aim of this study was to evaluate the reliability of a version of the diabetes quality-of-life (DQOL) questionnaire adapted and translated into Spanish. The DQOL questionnaire consists of 46 items and is not sensitive to treatment regimens or self-monitoring; therefore, the instrument might be useful to a wide range of patients with diabetes who use different methods of diabetes management. 105 patients with insulin-dependent diabetes mellitus volunteered to complete the questionnaire. This Spanish version of the DQOL achieved a high global internal consistency (alpha = 0.90), and some outcome similarities, such as more favourable scores among younger patients (up to 21 years of age) and adult male patients compared with the original DQOL. These data show that the Spanish version of the DQOL has a high internal consistency (reliability) and might be a useful comparable tool to evaluate quality of life in Spanish-speaking patients with diabetes mellitus.

Abstract
PURPOSE Since a previous qualitative study carried out by us showed the existence of an important influence of the particle size on the percolation thresholds and taking into account that the existing theoretical models can only provide qualitative explanation to this influence, the purpose of this work is to carry out the first quantitative study of the influence of the particle size over the drug percolation thresholds. METHODS Matrix tablets have been elaborated using potassium chloride as drug model and Eudragit RS-PM as matrix forming material. Five different KCl particle size fractions have been employed whereas the Eudragit RS-PM particle size was kept constant. In-vitro release assays were carried out for all the elaborated lots. The drug percolation thresholds were estimated following the method proposed by Bonny and Leuenberger. RESULTS A linear relationship has been found between the drug particle size and the corresponding drug percolation threshold. CONCLUSIONS This finding confirms the results previously obtained in our qualitative study and has important repercussions in the design of pharmaceutical solid dosage forms. If this linear behaviour is general, the percolation threshold can soon become a useful preformulation parameter.

Abstract
The role of excitatory synaptic activity at various brain regions in the development and spread of seizure activity has been investigated by the focal microinjection of 2-amino-7-phosphono-heptanoate (2-APH), a selective antagonist at the N-methyl-D-aspartate preferring receptor, or gamma-D-glutamyl-aminomethyl sulphonate (GAMS), a partially selective antagonist at the kainate receptor. In genetically epilepsy prone rats the seizure response to a loud sound in most effectively suppressed by focal injections of 2-APH, 0.1-1.0 nmol, in the inferior colliculus. Protection is also seen after injections of 2-APH, 25 nmoles, in the substantia nigra (pars reticulata) or the midbrain reticular formation. Motor limbic seizures induced by pilocarpine, 380 mg/kg intraperitoneally, are prevented by prior injection into the substantia nigra, pars reticulata, or the entopeduncular nucleus, of 2-APH, 10 nmol or 10 pmol, respectively. Similar protection follows the injection of 2-APH, 1-5 pmol in the piriform cortex. The convulsant effects of pilocarpine are also blocked by the focal injection of GAMS, 10 nmol in the entopeduncular nucleus. This experimental approach can indicate critical sites at which seizure activity is initiated in particular models (e.g., inferior colliculus in sound-induced seizures, and piriform cortex in limbic seizures) and the pathways controlling seizure expression, such as the basal ganglia outputs. It also identifies specific receptors at which anticonvulsant drugs may operate.
