Abstract
Introduction Patients with schizophreniform disorder(SD) and schizophrenia present similar symptoms, however, SD has a shorter duration, varying between at least 1 month and 6 months. Objectives To describe and analyse Schizophreniform disorder related hospitalizations in a national hospitalization database. Methods We performed a retrospective observational study using a nationwide hospitalization database containing all hospitalizations registered in Portuguese public hospitals from 2008 to 2015. Hospitalizations with a primary diagnosis of schizophreniform diso72.1-der were selected based on International Classification of Diseases version 9, Clinical Modification (ICD-9-CM) code of diagnosis 295.4x. Birth date, sex, residence address, primary and secondary diagnoses, admission date, discharge date, length of stay (LoS), discharge status, and hospital charges were obtained. Comorbidities were analysed using the Charlson Index Score. Independent Sample T tests were performed to assess differences in continuous variables with a normal distribution and Mann-Whitney-U tests when no normal distribution was registered. Results In Portuguese public hospitals, a total of 594 hospitalizations with a primary diagnosis of Schizophreniform disorder were registered during the 8-year study period. Most were associated to the male sex patients, 72.1% (n=428). The mean age at admission was 35.99 years and differed significantly between sexes (males - 34.44; females- 40.19; p<0.001). The median LoS was 17.00 days and the in-hospital mortality was 0.5% (n=3). Only 6.1% (n=36) of the hospitalization episodes had 1 or more registered comorbidities. Conclusions Hospitalizations with a primary diagnosis of Schizophreniform disorder occur more frequently in young male patients. This is the first nationwide study analysing all hospitalization episodes in Portugal. Disclosure No significant relationships.

Abstract
What happens when we unexpectedly see an attractive potential partner? Previous studies in laboratory settings suggest that the visualization of attractive and unattractive photographs influences the perception of time. The major aim of this research is to study time perception and attraction in a realistic social scenario, by investigating if changes in subjective time measured during a speed dating are associated with attraction. The duration of the dates was variable and participants had to estimate the time that passed. Among other measures, participants also rated the potential partners in terms of their physical attractiveness before and after the dates and reported if they would like to exchange contact with them. Results showed that, in a real speed dating situation, when there is a perception of the partner as being physically more attractive, women tend to overestimate the duration of that meeting, whereas men tend to underestimate its duration. Such changes may reflect evolutionary adaptations which make the human cognitive system more responsive in situations related to reproductive fitness.

Abstract
Introduction About 30% of individuals in ultra-high risk (UHR) of psychosis develop overt psychosis within 3 years, and about 40% of those who don’t will keep experiencing ongoing attenuated psychotic symptoms and persistent functional disability. During this prodromal period, it’s possible to prevent the transition to a first-episode psychosis. Objectives To conduct a short review of literature on the role of cognitive-behavioural therapy (CBT) in preventing psychosis in ultra-high risk patients. Methods We performed a literature search on PUBMED, using the query: “Cognitive Behavioral Therapy” [Mesh] AND “psychosis” AND “prevention”. We focused on data from systematic reviews, clinical trials and meta-analysis published on last 5 years, either in English or Portuguese. Results Some authors claim cognitive-behavioural therapy (CBT) as first-choice treatment in clients with ultra-high risk (UHR) for psychosis. CBT aims to normalize extraordinary experiences with education and to prevent delusional explanations. On a Japanese study, the total score of Positive and Negative Syndrome Scale (PANSS) significantly improved on post-intervention and follow-up assessments, with large effect sizes observed. Teaching families to apply CBT with their offspring may bolster therapeutic gains made in time-limited treatment. CBT showed an 83% probability of being more effective and less costly than routine care. Conclusions Patients with UHR for psychosis can be treated successfully with CBT to postpone and prevent the transition to a first-episode psychosis. CBT for UHR has been included in the European guidelines and awaits dissemination and implementation in mental health services.

Abstract
IntroductionA psychotic episode may be sufficiently traumatic to induce symptoms of post-traumatic stress disorder (PTSD), which could impact outcomes in first-episode psychosis (FEP). Yet, post-traumatic stress disorder is often left untreated and undiagnosed in the presence of psychosis.ObjectivesTo conduct a short review of literature on the prevalence and impact of PTSD after FEP.MethodsWe performed a literature search on PUBMED, using the query: “Stress Disorders, Post-Traumatic” [Mesh] AND “first episode” AND “psychosis”. We focused on data from systematic reviews, clinical trials and meta-analysis published on last 10 years, either in English or Portuguese.ResultsApproximately one in two people experience PTSD symptoms and one in three experience full PTSD, following a FEP. Prevalence may be higher in affective psychosis, inpatient samples and patients previously suffering from depression and anxiety. PTSD Symptom Scale – Self-Report (PSS-SR) can be a useful screening instrument, but there is no established evidence-based intervention for PTSD in people with FEP. Coercive intervention such as involuntary hospitalization, seclusion, restraint or being forced to take medication, as well as being around sick or anxious patients, can be upsetting and traumatizing.ConclusionsOur data showed high rates of psychosis-related PTSD. To prevent PTSD, conditions of hospitalization should be optimized and the use of coercive treatments should be limited. Subjects with recent-onset psychosis should be screened for PTSD symptoms. Evidence-based interventions to treat PTSD symptoms in the context of FEP are needed to address this burden and improve outcomes.

Abstract
Introduction Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disorder characterized by neuropsychiatric symptoms before progressing to seizures, complex movement disorder, autonomic dysfunction and hypoventilation. Objectives Presenting a review of the psychiatric manifestations of anti-NMDAR encephalitis. Methods Search on Pubmed® and Medscape® databases with the following keywords: “psychiatric”, “anti-NMDA receptor encephalitis” and “anti-NMDAR encephalitis”. We focused on data from systematic reviews and meta-analyzes. The articles were selected by the authors according to their relevance. Results Studies show that 77% to 95% of patients with anti-NMDAR encephalitis initially present psychiatric manifestations. Age and sex distribution are young women, and the frequency of cases is lower after 40 years of age. The most common psychiatric symptoms are agitation (59%) and psychotic symptoms (54%). The psychotic symptoms more common are visual (64%), auditory (59%) hallucinations and persecutory delusions (73%). Catatonia is described in 42% of patients. Antipsychotic treatment induces an adverse drug reaction (33%), the neuroleptic malignant syndrome represents 22% of the cases. Delays in distinguishing this disease from a psychiatric disorder can have serious complications, with a mortality of up to 25% in patients receiving limited or delayed immunotherapy. Conclusions It’s important to consider anti-NMDAR encephalitis in the differential diagnosis of patients with an acute onset psychosis or unusual psychiatric symptoms. Antipsychotic treatment should be use with caution when suspected or confirmed anti-NMDAR encephalitis. Without appropriate treatment, patients may suffer a protracted course with significant long-term disability or death. A clinical index of suspicion is required to identify patients who would benefit from cerebrospinal fluid testing and immunotherapies. Disclosure No significant relationships.

Abstract
Introduction Impulse control disorders (ICDs) are an adverse effect of dopamine agonists (DAAs) that affects the quality of life and can lead to legal, criminal and familiar problems. Objectives Presenting a review of the mechanisms, prevalence and factors associated with the development of an ICD due to DAA use. Methods Search on Pubmed database with combination of the following keywords were used: “Impulse control disorders”, “dopamine agonist” or “therapy”. We focused on data from studies published between 2015 and 2020. The articles were selected by the author according to their relevance. Results DAAs are mainly indicated in the treatment of Parkinson’s Disease (PD), and are also used on symptoms of restless legs syndrome (RLS) and prolactinoma or lactation inhibition. Dopamine replacement therapy act on dopamine receptors in the nigrostriatal and the reward pathways, which plays a role in addictive behavior. The prevalence of ICDs ranged from 2.6 to 34.8% in PD patients and a lower prevalence in RLS patients. Some of the ICDs reported were pathological gambling, hypersexuality, compulsive shopping, obsessive hobbying, punding, and compulsive medication use. The factors associated with the development include the type of DAAs, dosage, male gender, younger age, history of psychiatric symptoms, earlier onset of disease, longer disease duration, and motor complications in PD. Conclusions Further studies are needed to clarify the pathophysiology of the ICD in DAA therapy and determinate premorbid risk factors. The percentage of patients with ICDs is underrated, so it’s important to improve the patient’s evaluation, using validated and consensual assessment tools.

Abstract
Introduction Frontotemporal dementia (FTD) is a group of neurodegenerative disorders characterized by behavioral or language changes with progressive executive dysfunction. It´s subdivided into two variants, the behavioral and language variants. The phenocopy syndrome of frontotemporal dementia (phFTD) mimics the behavioral variant, but doesn´t show frontotemporal atrophy in neuroimaging and doesn´t progress to frank dementia over the years. Objectives Presenting a review of phenocopy syndrome of frontotemporal dementia. Methods Search on Pubmed® and Medscape® databases with the following keywords: “frontotemporal dementia and phenocopy” or “FTD phenocopy”. We focused on data from systematic reviews and meta-analyzes published in the last five years. The articles were selected by the authors according to their relevance. Results Mutations in GRN and MAPT gens and genetic expansion of C9orf72 have been identified. The discovery of the C9orf72 expansion in psychiatric disorders (psychosis, bipolar disorder or depressive disorder), for some authors, represents that phFTD is a psychiatric pathology. In fact, there’s a higher frequency of psychiatric and psychological symptoms in phFTD compared to the variants of FTD. Usually are male patients who don´t have significant cognitive deficits, with preservation of executive functions and episodic memory. Until now, there are no definitive biomarkers of the disease. The prognosis is more benigne, unlike FTD, which has an average survival of 3 years since diagnosis. Conclusions phFTD is a clinical and scientific challenge. The neurobiological bases remain unknown, requiring further studies in this field. The identification of markers that can differentiate patients with typical FTD and phFTD can facilitate prognosis orientation and pharmacological an non-pharmacological treatment.

Abstract
Regular aerobic exercise training has a wide range of beneficial cardiac effects, but recent data also show that acute very strenuous aerobic exercise may impose a transient cardiac exhaustion. The aim of this study was to assess the response to acute high-intensity aerobic exercise on properties of mitochondrial respiration, cardiomyocyte contractile function, Ca2+ handling and transcriptional changes for key proteins facilitating Ca2+ handling and endoplasmic reticulum (ER) stress responses in type 2 diabetic mice. Diabetic mice were assigned to either sedentary control or an acute bout of exercise, consisting of a 10×4 minutes high-intensity interval treadmill run. Mitochondrial respiration, contractile and Ca2+ handling properties of cardiomyocytes were analysed 1 hour after completion of exercise. Gene expression levels of key Ca2+ handling and ER stress response proteins were measured in cardiac tissue samples harvested 1 hour and 24 hours after exercise. We found no significant changes in mitochondrial respiration, cardiomyocyte contractile function or Ca2+ handling 1 hour after the acute exercise. However, gene expression of Atp2a2, Slc8a1 and Ryr2, encoding proteins involved in cardiomyocyte Ca2+ handling, were all significantly upregulated 24 hours after the acute exercise bout. Acute exercise also altered gene expression of several key proteins in ER stress response and unfolded protein response, including Grp94, total Xbp1, Gadd34, and Atf6. The present results show that despite no significant alterations in functional properties of cardiomyocyte function, Ca2+ handling or mitochondrial respiration following one bout of high intensity aerobic exercise training, the expression of genes involved in Ca2+ handling and key components in ER stress and the unfolded protein response were changed. These transcriptional changes may constitute important steps in initiating adaptive remodelling to exercise training in type 2 diabetes.

Abstract
Abstract
Problem
Different countries have incorporated models of decentralization in their health reforms to achieve efficiency, by increasing the training of local governments, responsibility and gains in areas such as quality, costs and equity. In Portugal, the 21st government program established the autonomy of local authorities and the democratic decentralization of public administration. Accordingly, a decentralization law was approved and local governments have now a crucial role on health policies.
Description of the Problem
For this framework, a situational diagnosis and an intersectoral approach to policies are needed. This is an observational, analytical and cross-sectional study developed at council level in two Portuguese municipalities. This study aims to: Adjust responses to health needs at the local level; Set priorities by taking into account installed capacity and responses to populations; Promote the articulation between entities; Strengthen the focus on health promotion and healthy lifestyles; Strengthen health interventions in educational communities; Promote the creation of programs at local level, in conjunction with the national level, to reduce inequalities.
Results
The preliminary results in health, social and economic indicators show that this framework, while taking in consideration population characteristics, allows the development of local strategies regarding health services coverage, health services type and medication. At council level, the preliminary results also show a lack of data on healthy lifestyles and social indicators.
Lessons
The implementation of a decentralization process involves a broad range of requirements such as a situational diagnosis, strategies development and a periodic update of quality life and health indicators. Those are needed to assess council level priorities, which allow the development of public policies and interventions, in line with population characteristics, to tackle health inequalities and inequities.
Key messages
Performance improvement of health system is linked to the implementation of local citizen centred policies. These are actions which promote quality of life through health-friendly ecosystems. The local health intervention has contributed to promote inequalities reduction, increasing equity and dynamize new frameworks of organization with individual and community participation.

Abstract
Impulsiveness has an important role in suicide behaviour and substance abuse.In this context, it's important to assess suicide risk among drug users and to determine which factors play a protective role and which factors increase the risk.In this study the authors propose to determine the prevalence of actual or past suicidal ideation in a sample of substance users; to determine the prevalence of previous suicidal behaviours in the same sample; and to study the relation with clinical and sociodemographic variables.The sample included 119 patients with drug addiction behaviours receiving treatment in an inpatient detoxication unit (Unidade de Desabituação do Norte do IDT - Instituto da Droga e das Toxicodependências), admitted between May 2010 and July 2010.Data was obtained from the patient clinical chart, including the admission protocol form.SPSS was used for statistical analysis.The results founded were:18,5% (n = 22) had previous suicidal ideation at least once in their lifetime.2,5% (n = 3) had suicidal ideation at admission.10,9% (n = 13) had previous suicidal attempts.According to literature, in general population, lifetime prevalence of suicidal ideation is 10–18% and history of suicidal attempt is 3–5%.In the studied sample, suicidal ideation during lifetime is slightly raised (18,5%) and history of suicidal behaviours is strongly higher (10.9%).These data suggest a raised suicidal risk in drug abuse population, probably reflecting a higher impulsiveness in this population.

Abstract
BACKGROUND AND PURPOSE Co-occurrence of local anisotropic gradient orientations (COLLAGE) is a recently developed radiomic (computer extracted) feature that captures entropy (measures the degree of disorder) in pixel-level edge directions and was previously shown to distinguish predominant cerebral radiation necrosis from recurrent tumor on gadolinium-contrast T1WI. In this work, we sought to investigate whether COLLAGE measurements from posttreatment gadolinium-contrast T1WI could distinguish varying extents of cerebral radiation necrosis and recurrent tumor classes in a lesion across primary and metastatic brain tumors. MATERIALS AND METHODS On a total of 75 gadolinium-contrast T1WI studies obtained from patients with primary and metastatic brain tumors and nasopharyngeal carcinoma, the extent of cerebral radiation necrosis and recurrent tumor in every brain lesion was histopathologically defined by an expert neuropathologist as the following: 1) "pure" cerebral radiation necrosis; 2) "mixed" pathology with coexistence of cerebral radiation necrosis and recurrent tumors; 3) "predominant" (>80%) cerebral radiation necrosis; 4) predominant (>80%) recurrent tumor; and 5) pure tumor. COLLAGE features were extracted from the expert-annotated ROIs on MR imaging. Statistical comparisons of COLLAGE measurements using first-order statistics were performed across pure, mixed, and predominant pathologies of cerebral radiation necrosis and recurrent tumor using the Wilcoxon rank sum test. RESULTS COLLAGE features exhibited decreased skewness for patients with pure (0.15 ± 0.12) and predominant cerebral radiation necrosis (0.25 ± 0.09) and were statistically significantly different (P < .05) from those in patients with predominant recurrent tumors, which had highly skewed (0.42 ± 0.21) COLLAGE values. COLLAGE values for the mixed pathology studies were found to lie between predominant cerebral radiation necrosis and recurrent tumor categories. CONCLUSIONS With additional independent multisite validation, COLLAGE measurements might enable noninvasive characterization of the degree of recurrent tumor or cerebral radiation necrosis in gadolinium-contrast T1WI of posttreatment lesions.

Abstract
BACKGROUND AND PURPOSE Despite availability of advanced imaging, distinguishing radiation necrosis from recurrent brain tumors noninvasively is a big challenge in neuro-oncology. Our aim was to determine the feasibility of radiomic (computer-extracted texture) features in differentiating radiation necrosis from recurrent brain tumors on routine MR imaging (gadolinium T1WI, T2WI, FLAIR). MATERIALS AND METHODS A retrospective study of brain tumor MR imaging performed 9 months (or later) post-radiochemotherapy was performed from 2 institutions. Fifty-eight patient studies were analyzed, consisting of a training (n = 43) cohort from one institution and an independent test (n = 15) cohort from another, with surgical histologic findings confirmed by an experienced neuropathologist at the respective institutions. Brain lesions on MR imaging were manually annotated by an expert neuroradiologist. A set of radiomic features was extracted for every lesion on each MR imaging sequence: gadolinium T1WI, T2WI, and FLAIR. Feature selection was used to identify the top 5 most discriminating features for every MR imaging sequence on the training cohort. These features were then evaluated on the test cohort by a support vector machine classifier. The classification performance was compared against diagnostic reads by 2 expert neuroradiologists who had access to the same MR imaging sequences (gadolinium T1WI, T2WI, and FLAIR) as the classifier. RESULTS On the training cohort, the area under the receiver operating characteristic curve was highest for FLAIR with 0.79; 95% CI, 0.77-0.81 for primary (n = 22); and 0.79, 95% CI, 0.75-0.83 for metastatic subgroups (n = 21). Of the 15 studies in the holdout cohort, the support vector machine classifier identified 12 of 15 studies correctly, while neuroradiologist 1 diagnosed 7 of 15 and neuroradiologist 2 diagnosed 8 of 15 studies correctly, respectively. CONCLUSIONS Our preliminary results suggest that radiomic features may provide complementary diagnostic information on routine MR imaging sequences that may improve the distinction of radiation necrosis from recurrence for both primary and metastatic brain tumors.

Abstract
Preclinical trials are essential to the development of scientific technologies. Remarkable molecular and cellular research has been done using small animal models. However, significant differences exist regarding the articular behavior between these models and humans. Thus, large animal models may be more appropriate to perform trials involving the temporomandibular joint (TMJ). The aim of this work was to make a morphological (anatomic dissection and white light 3D scanning system), histological (TMJ in bloc was removed for histologic analysis) and biomechanical characterization (tension and compression tests) of sheep TMJ comparing the obtained results with human data. Results showed that sheep processus condylaris and fossa mandibularis are anatomically similar to the same human structures. TMJ disc has an elliptical perimeter, thinner in the center than in periphery. Peripheral area acts as a ring structure supporting the central zone. The disc cells display both fibroblast and chondrocyte-like morphology. Marginal area is formed by loose connective tissue, with some chondrocyte-like cells and collagen fibers in diverse orientations. Discs obtained a tensile modulus of 3.97±0.73MPa and 9.39±1.67MPa, for anteroposterior and mediolateral assessment. The TMJ discs presented a compressive modulus (E) of 446.41±5.16MPa and their maximum stress value (σmax) was 18.87±1.33MPa. Obtained results suggest that these animals should be considered as a prime model for TMJ research and procedural training. Further investigations in the field of oromaxillofacial surgery involving TMJ should consider sheep as a good animal model due to its resemblance of the same joint in humans.

Abstract
OBJECTIVE We examined the relationship between biological rhythms and severity of depressive symptoms in subjects with bipolar disorder and the effects of biological rhythms alterations on functional impairment. METHOD Bipolar patients (n = 260) and healthy controls (n = 191) were recruited from mood disorders programs in three sites (Spain, Brazil, and Canada). Parameters of biological rhythms were measured using the Biological Rhythms Assessment in Neuropsychiatry (BRIAN), an interviewer administered questionnaire that assesses disruptions in sleep, eating patterns, social rhythms, and general activity. RESULTS Multivariate analyses of covariance showed significant intergroup differences after controlling for potential confounders (Pillai's F = 49.367; df = 2, P < 0.001). Depressed patients had the greatest biological rhythms disturbance, followed by patients with subsyndromal symptoms, euthymic patients, and healthy controls. Biological rhythms and HAMD scores were independent predictors of poor functioning (F = 12.841, df = 6, P < 0.001, R2 = 0.443). CONCLUSION Our study shows a dose-dependent association between the severity of depressive symptoms and degree of biological rhythms disturbance. Biological rhythms disturbance was also an independent predictor of functional impairment. Although the directionality of this relationship remains unknown, our results suggest that stability of biological rhythms should be an important target of acute and long-term management of bipolar disorder and may aid in the improvement of functioning.

Abstract
BACKGROUND The incidence of bacterbilia in cholelithiasis remains controversial. The positivity of cultures ranges from 0 to 73 per cent. The aim of this study was to employ the polymerase chain reaction (PCR) to detect bacterial DNA in gallbladder bile extracted during elective laparoscopic cholecystectomy, and to compare PCR findings with those of bile culture. METHODS Bile samples from 84 laparoscopic cholecystectomies were collected for culture and PCR analysis. RESULTS Positive results for bacterbilia were found in 42 (50 per cent) of 84 patients by PCR but in only 16 patients (19 per cent) by culture (P < 0.001). Agreement between the two methods was seen in 44 samples (52 per cent), which were negative in 35 cases. Pathological examination showed chronic cholecystitis in 69 cases (82 per cent) and acute cholecystitis in 15 (18 per cent). Thirty-three (48 per cent) of the patients with chronic cholecystitis were PCR positive but only ten (14 per cent) were culture positive (P < 0.001). Only culture results correlated with findings on pathological examination (P = 0.033). CONCLUSION PCR is more sensitive in detecting bacterial contamination of gallbladder bile in cholecystitis than conventional culture. The clinical relevance of this high sensitivity remains unclear.

Abstract
PURPOSE The aim of this study was to assess the reliability of transperineal ultrasonography (TPUS) in the pre-operative identification of the internal opening of anal fistulas compared to conventional proctological examination and operative findings. METHODS Forty-three patients with anal fistula were assessed by TPUS with and without the use of hydrogen-peroxide injection (E-TPUS) in an attempt to identify the internal opening. Results were compared to preoperative conventional examination and operative findings. RESULTS Operative assessment showed an anterior internal opening in 29 patients (67.4%) and a posterior opening in 14 (32.6%). Compared to the operative findings, the agreement rate for the identification of the internal opening was 74.4% for physical examination alone, 93.0% for TPUS and 90.7% for E-TPUS. Physical examination was less accurate in detecting the internal opening than both TPUS (p=0.014) and E-TPUS (p=0.026). CONCLUSIONS TPUS and E-TPUS are superior to physical examination in the identification of internal openings in anal fistulas. Hydrogen peroxide injection does not provide additional advantages.

Abstract
This study aimed to develop a Walking Pattern Evaluation System during Hypogravity Simulation (SAMSH), which included the adaptation of a body suspension device, the instrumentation of a treadmill and the development of a virtual environment. SAMSH was developed using one subject. Kinematic analyses were performed whilst one individual was walking on the treadmill during body weight reduction simulating the gravitational forces of the Moon (reduction of 60%) and Mars (reduction of 30%) with and without virtual reality glasses (Head Mounted Display, HMD). The walking pattern was evaluated by means of knee and ankle electrogoniometers, foot switches placed on the front and back part of the plantar region, and five video cameras. Results showed that the body weight reduction during Moon simulation alter the walking pattern, including the increase in step time, contact time, step length and aerial time, and the decrease of walking cadence time (steps per minute). The findings of this study also suggested that hypogravity simulation reduces walking effort. The utilization of the HMD allowed the evaluation of the head position three-dimensionally during hypogravity simulation. The virtual environment reduced postural balance, due to the absence of visual input, which was evidenced by a protective extension reaction.

Abstract
Bovine ocular squamous cell carcinoma (OSCC) is the second most common cause of rejection due to neoplasia in slaughterhouses on Sao Miguel Island, Azores, and accounts for significant economic losses. To obtain a better insight into the genesis and neoplastic transformation process of bovine OSCC, abnormal protein expression and proliferation index were assessed by the immunohistochemical evaluation of p53 and Ki67, respectively. OSCC samples were collected from 15 bovines and were classified histologically according to the degree of differentiation into three categories: poorly, moderately, and well differentiated. Immunohistochemistry using polyclonal anti-human p53 antibody and polyclonal anti-human Ki67 antibody was performed. Ten of 15 tumors tested were immunoreactive for p53. Twelve tumors demonstrated Ki67 expression. As in human squamous cell carcinoma, p53 overexpression is frequent in bovine OSCC, providing support for a possible role of the protein in the pathogenesis of this neoplasia. No correlation between the percentage of p53 stained nuclei and the degree of differentiation was observed, although different patterns of staining were seen according to the degree of keratinization of the tumor cells. With the exception of the moderately differentiated OSCC group, Ki67 index showed significant correlation with the histologic pattern, increased proliferation being found in poorly differentiated OSCC (P = 0.013).

Abstract
The distribution of vasoactive intestinal peptide (VIP)- and calcitonin gene-related peptide (CGRP)-immunoreactive nerves and 125I-labeled VIP- and CGRP-binding sites was studied in the hamster seminal vesicle of 12-, 30- and 60-day-old animals. In addition, the general innervation of the seminal vesicle was examined using the general neuronal marker synaptophysin. Our results show that the densities of the overall (synaptophysin immunoreactive) and CGRP-immunoreactive innervation is constant during the post-natal development of the gland. However, a significant decrease in VIP-containing nerves is observed at the end of puberty. The autoradiographic study revealed that in 12-day-old animals, the epithelium presents VIP binding sites. However, in 30-day-old animals, VIP binding sites are observed in the epithelium of only a few clumps of acini. In 60-day-old animals, the gland is composed of acini with dilated lumina where VIP binding sites are not detected. In all groups studied the epithelium does not exhibit CGRP binding sites. The seminal vesicle muscle layer displays specific binding sites for both VIP and CGRP at all post-natal developmental times, but the density of VIP binding sites is higher in 12- than in 30- and 60-day-old animals. Our results, showing the presence of specific VIP and CGRP binding sites during the development of the hamster seminal vesicle, suggest that these neuropeptides may be involved in the growth and differentiation of the gland.

Abstract
The presence and distribution of 125I-vasoactive intestinal polypeptide (VIP) binding sites in blood vessels supplying the hamster seminal vesicle was studied using a receptor autoradiographic technique before and following castration. 125I-VIP binding was studied in intact animals, in animals under a 15-day period of castration and in animals under the same period of castration but submitted to a further 15-day period of testosterone treatment. Our results show that, in the seminal vesicle, VIP-binding sites are localized in the gland smooth muscle coat and arterial smooth muscle. A 15-day castration period abolishes 125I-VIP binding to vascular smooth muscle but has no effect on 125I-VIP binding to the gland smooth muscle coat. Treatment with testosterone restores 125I-VIP binding to the vascular smooth muscle, completely reversing the effect of castration. Our results indicate that VIP-binding sites in the smooth muscle wall of arteries supplying the hamster seminal vesicle are under androgenic control and are more sensitive to androgen deprivation that VIP-binding sites associated to the gland smooth muscle coat.

Abstract
We report two Portuguese sisters aged 9 and 12 years with symmetric well-circumscribed radiolucent cystic lesions on the long bone metaphysis of the hands and feet. The eldest also has soft tissue calcifications. They have no dysmorphic features and their growth is normal. Plasma values of parathyroid hormone (PTH), calcium, phosphorus, magnesium, and alkaline phosphatase are normal. Cerebral computed tomography (CT) scan shows no intracranial calcifications. A Raynaud phenomenon became evident during the last year in the eldest. The incisional biopsy of the left proximal metatarsial was performed through an area of typical radiographic appearance. The pathology specimen consisted of enchondroma tissue. The present cases are an extremely rare instance of this pathology, with symmetrical involvement of the hands and feet and a familial incidence.

Abstract
Hot perineal baths have been prescribed for the treatment of painful anorectal conditions such as anal fissures and perianal hematomas or for the postoperative care of hemorrhoidectomy. Despite this widely accepted benefit, no studies have been performed to determine whether there is a rational explanation for this procedure. Anorectal manometry was performed in 40 control subjects with no anorectal complaints before and after a hot perineal bath. No significant difference was found between anal pressures at rest or during voluntary contraction before and after the bath. We conclude from this study that no relaxation of anal sphincters can be obtained by hot perineal baths in normal subjects.

Abstract
Long-term results of postanal repair are poor. Many patients with neuropathic incontinence have evidence of anterior pelvic floor weakness. A more comprehensive surgical repair has therefore been developed that involves postanal repair, anterior levatorplasty, and external sphincter plication. Primary total pelvic floor repair was performed in 22 women with neuropathic fecal incontinence. Fourteen patients who remained incontinent after conventional postanal repair underwent secondary anterior levatorplasty and external sphincter plication (two stages). Neither resting nor squeeze anal pressures were influenced by any of these procedures. However, pelvic floor descent at rest and straining was significantly decreased following primary total pelvic floor repair and secondary pelvic floor repair (p less than 0.05) but not by postanal repair. Complete continence for liquids, solids, and flatus was achieved in 41% of patients after primary total pelvic floor repair and in 14% after secondary anterior levatorplasty and external sphincter plication, but in only 4% after postanal repair. Only one patient after primary total pelvic floor repair and one after secondary anterior levatorplasty and external sphincter plication had persistent incontinence compared with 18 (38%) after postanal repair.

Abstract
Pelvic floor movements were assessed by videoproctography in 126 subjects: neuropathic fecal incontinence patients (n = 44), chronic constipation patients (n = 52), and controls (n = 30). A significantly lower pelvic floor position at rest and a more obtuse anorectal angle were found in incontinent patients than in controls (P less than 0.01). Constipated patients showed no significant difference from controls at rest. There was less pelvic floor movement during contraction in incontinent patients than in controls, indicating a flaccid, noncontractile pelvic floor in neuropathic incontinence. Movement during contraction in constipated subjects was also less than in controls. Changes in the pelvic floor position during straining were the same as in controls. These data indicate that the pelvic floor is flaccid and noncontractile in neuropathic fecal incontinence, which supports the concept of a progressive neuropathy involving the sacral outflow. Similar changes are not seen at rest in patients with constipation even though they have a long history of straining.

Abstract
The anorectal angle can be determined either by constructing a straight line along the lower border of the rectum (Method A) or by using the central longitudinal axis of the lower rectum (Method B). We have used a computer program to derive the centroid of the rectum for Method B. The coefficients of variation for angles measured at rest, during maximum pelvic floor contraction, and during attempted defecation were 0.616, 0.351, and 0.358, respectively, compared with 0.993, 0.972, and 0.968 for Method B. The presence of a rectocele had no influence on the measurement of the anorectal angle in incontinence, but there was a significant difference in assessment of the angle between constipated patients (P less than 0.05) and controls (P less than 0.05). Posterior indentation of the rectum had no significant influence on measurement of the angle in any group. These data indicate that a computer-derived centroid is more reliable for measurement of angles, but a correction factor for anterior rectocele is needed in constipated patients and controls.

Abstract
Assessment of anal function is now regarded as an important aspect of the proctologic examination in assessment of patients with disordered defecation. Conventional electromyography is invasive and often not repeatable because of patient discomfort. Noninvasive surface intra-anal EMG was evaluated as a method of assessing sphincter function in 76 subjects. A significant correlation was found between intra-anal EMG and anal manometry at rest and during a maximum squeeze effort (P less than 0.01). Intra-anal EMG was found to be reproducible when evaluated by 2 independent observers (P less than 0.05) and may prove a reliable portable noninvasive method of assessing sphincter function.

Abstract
The surgical treatment of idiopathic faecal incontinence remains a difficult problem particularly in those cases where advanced neuropathy is present. The physiological basis for the post-anal repair have now been questioned and the long term functional results seem to be rather unsatisfactory. Pelvic floor repair is a more comprehensive approach with encouraging initial results which need to be assessed in a long term experiment and in a prospective randomised comparison with conventional post-anal repair. Gracilis transposition in idiopathic faecal incontinence has shown very disappointing results and has probably no role in the treatment of this condition. Intestinal stoma in very advanced cases may occasionally provide important hygienic and psychological benefit.

Abstract
Anorectal function is known to be influenced by age but there is only scanty information about the effect of ageing on pelvic floor dynamics. Pelvic floor movements were assessed by videoproctography in two groups of ten control females (mean age of 30.5 and 60.7 years, respectively). A significantly lower pelvic floor position was found at rest in the older group (p = 0.02), but younger controls showed an increased pelvic floor descent during straining (p = 0.01). These results suggest that the pelvic floor is affected by progressive denervation but descent during straining tends to decrease with advancing age.

Abstract
Anorectal myectomy has been shown to provide clinical benefit to patients with outlet obstruction. Long-term results of anorectal myectomy have been evaluated in 57 patients operated on between February 1984 and February 1988 with a median follow-up of 24 months. Overall improvement was recorded in only 31 percent of patients. Spontaneous evacuation without the need for laxatives was recorded in only 11 patients (19 percent), while 38 (67 percent) had no functional improvement. Results were independent of preoperative colonic transit or histologic evidence of aganglionosis. Anorectal myectomy identified aganglionosis in 23 percent of patients with chronic constipation, but there was minimal long-term benefit from the procedure.

Abstract
Videoproctography was performed in 40 patients after restorative proctocolectomy to evaluate pouch emptying, anopouch angle, and pelvic floor movement in relationship to functional outcome. Results were compared between the two different pouch designs tested and a control group of 26 patients who had an intact rectum. There was no difference in emptying between the two pouch designs or compared with the control subjects. Emptying did not influence either the frequency of defecation or patient soiling rate. The presence of an anal stricture was associated with poor emptying in each case in the pouch group. Anorectal angle was no different between the different pouch designs or compared with the control group at rest, during pelvic floor contraction, or attempted defecation. A similar finding was obtained with anorectal angle position and movement during pelvic floor contraction and attempted defecation in both pouch design groups and when compared with normal rectum. This study shows that the only factor that is consistently associated with poor pouch emptying is the presence of an anal stricture.

Abstract
Two treatment policies for rectal prolapse were prospectively assessed between April 1986 and January 1989. Sixteen patients had a Marlex mesh posterior rectopexy alone and 13 underwent a sigmoidectomy combined with a sutured posterior rectopexy. Preoperative and post-operative assessment included manometry, a saline infusion test and video-proctography. Hospital stay, control of prolapse and complications were comparable in both groups. Restoration of continence occurred in nine of the 12 incontinent patients after Marlex rectopexy, compared with six of nine after sutured rectopexy and sigmoidectomy. Constipation persisted in three patients who were constipated before operation and in four of 13 who had previously normal bowel habits became constipated after Marlex rectopexy; constipation persisted in one of five previously constipated patients while none with previously normal bowel habits became constipated after sutured rectopexy and sigmoidectomy. Sigmoidectomy combined with sutured rectopexy was safe and as efficient as Marlex rectopexy in prolapse control and improvement of continence; significantly fewer patients were constipated (one of 13) after sigmoidectomy than following rectopexy alone (seven of 16). A randomized trial now seems justified.

Abstract
Early evaluation of anorectal myectomy in this unit suggested that it might provide clinical benefit to patients with outlet obstruction. Long term results of anorectal myectomy are now available in 63 patients operated on between February 1984 and February 1988 with a median follow-up of 30 months. Spontaneous rectal evacuation without the need for laxatives was recorded in only 11 patients (17 per cent), while 44 (70 per cent) achieved no functional improvement. Mild incontinence developed in 6 patients (10 per cent). Results were independent of preoperative colonic transit or histological evidence of aganglionosis.
