Abstract
INTRODUCTION Anterior glenohumeral dislocation in patients older than 60 years is related to rotator cuff lesion because of its pre-existing degenerative condition. However, in this age group, the scientific evidence fails to elucidate whether rotator cuff lesions are the cause or consequence of recurrent shoulder instability. The objective of this paper is to describe the prevalence of rotator cuff injuries in a series of consecutive shoulders in patients older than 60 years who suffered a first episode of traumatic glenohumeral dislocation, and its correlation with rotator cuff injuries in both shoulders. METHODS Retrospectively, 35 patients over 60 years of age who had a first episode of unilateral traumatic anterior glenohumeral dislocation and who had MRI of both shoulders were studied, evaluating both shoulders with MRI to determine the structural damage correlation of the rotator cuff and long head of the biceps between them. RESULTS When assessing the existence of partial or complete injury to the supraspinatus and infraspinatus tendons, the concordance on the affected and healthy sides, we have shown concordant results on both sides in 88.6 and 85.7%, respectively. The Kappa concordance coefficient was 0.72 for supraspinatus and infraspinatus tendons tear. Of the total of 35 cases evaluated, 8 (22.8%) presented at least some alteration in the tendon of the long head of the biceps on the affected side and only one (2.9%) on the healthy side, where the Kappa coefficient of concordance was 0.18. Of the 35 cases evaluated, 9 (25.7%) presented at least some retraction in the tendon of the subscapularis muscle on the affected side, while no participant showed signs of retraction in the tendon of this muscle on the healthy side. CONCLUSIONS Our study has found a high correlation of the presence of a postero-superior rotator cuff injury after presenting a glenohumeral dislocation between the shoulder that has suffered the event and the presumably healthy contralateral shoulder. Nevertheless, we have not found this same correlation with subscapularis tendon injury and medial biceps dislocation.

Abstract
Feline coronavirus (FCoV) exists as two different genotypes, FCoV type I and II, each including two biotypes, feline enteric coronavirus (FECV) and feline infectious peritonitis virus (FIPV), the latter being a virulent variant originating from the former virus. Recently, two amino acid substitutions, M1058L and S1060A, within the spike protein have been associated to the FECV/FIPV virulence change. In this study, we have analysed the frequency of detection of such mutations in FIPV and FECV strains circulating in Italian cats and obtained information about their evolutionary relationships with reference isolates. A total of 40 FCoV strains, including 19 strains from effusions or tissue samples of FIP cats and 21 strains from faecal samples of non-FIP cats, were analysed. Mutation M1058L was detected in 16/18 FCoV-I and 1/1 FCoV-II strains associated with FIP, while change S1060A was presented by two FIPV strains. By phylogenetic analysis, FCoV sequences clustered according to the genotype but not according to the biotype, with FECV/FIPV strains recovered from the same animal being closely related. Further studies are needed to better define the genetic signatures associated with the FECV/FIPV virulence shift.

Abstract
OBJECTIVE To present the different surgical procedures in the treatment of objective femoropateral instability, including osteotomy of anterior tibial tuberosity and femoral trocleoplasty. MATERIAL AND METHODS With a prospective 5-year follow-up design that included 21 patients (21 knees) treated for relapsing patellar dislocation between March 2010 and August 2014, treated surgically using 2 different techniques depending on the type of basic structural instability. To determine this, the Caton-Deschamps X-Ray Index (for the evaluation of the patellar height) and tomographic parameters were analyzed to assess the troclear configuration and distance from the anterior tibial tuberosity to the femoral trochlea (TT-TG) in the overlapping of images in the axial plane. RESULTS We have had satisfactory results both with the transfer of the anterior tibial tuberosity and with the trocleoplasty. In both procedures, a reconstruction of the medial patelo-femoral ligament (LPFM) was performed. CONCLUSION Recurrence of instability is very rare after these procedures and is more likely to result from undiagnosed or underestimated associated abnormalities. Precise preoperative planning is required to determine the patellar height, location of the anterior tibial tuberosity, and troclear configuration for satisfactory results.

Abstract
OBJECTIVE Seasonal variation may occur in many different diseases hence influencing awareness in clinical practice. This study aimed to establish seasonal variations of acute pancreatitis by using a validated chronobiological analysis. PATIENTS AND METHODS All cases of acute pancreatitis consecutively observed in fifteen years, i.e., from January 2003 to December 2017, at St. Anna University Hospital of Ferrara, Italy, were included in this study. Accurate statistical and logistic regression analyses were applied to our database. RESULTS A total number of 1883 consecutive cases of acute pancreatitis were observed. A significant peak was identified in the summer period (p=0.014). Patient stratification, according to age, showed that elderly people had an increased incidence of acute pancreatitis in autumn and summer (being the biliary stone disease the main cause, p=0.011) vs. other seasons (p=0.003). Mortality occurred more prominently in males vs. females, although the latter gender was more prone to acute pancreatitis (p=0.017). CONCLUSIONS In a single centre of Northern East of Italy, we demonstrated that acute pancreatitis had a clear seasonal variation with a prominent incidence during summer. Various associated factors could contribute to this chronobiological pattern, including gender, age, and biliary stone disease.

Abstract
Tomato high pigment (hp) mutants are characterized by their exaggerated photoresponsiveness. Light-grown hp mutants display elevated levels of anthocyanins, are shorter and darker than wild-type plants, and have dark green immature fruits due to the overproduction of chlorophyll pigments. It has been proposed that HP genes encode negative regulators of phytochrome signal transduction. We have cloned the HP-2 gene and found that it encodes the tomato homolog of the nuclear protein DEETIOLATED1 (DET1) from Arabidopsis. Mutations in DET1 are known to result in constitutive deetiolation in darkness. In contrast to det1 mutants, tomato hp-2 mutants do not display any visible phenotypes in the dark but only very weak phenotypes, such as partial chloroplast development. Furthermore, whereas det1 mutations are epistatic to mutations in phytochrome genes, analysis of similar double mutants in tomato showed that manifestation of the phenotype of the hp-2 mutant is strictly dependent upon the presence of active phytochrome. Because only one DET1 gene is likely to be present in each of the two species, our data suggest that the phytochrome signaling pathways in which the corresponding proteins function are regulated differently in Arabidopsis and tomato.

Abstract
Neurolathyrism is a degenerative disorder due to an excessive consumption of Lathyrus sativus (LS) seeds, which contain the neurotoxic amino acid beta-N-oxalylamino-L-alanine. In this study, a population of Wistar rats was fed a diet with LS seeds up to 8 months. Two control groups were chosen, one receiving standard food and the other Cicer arietinum seeds (a nontoxic legume). At the end of the dietary period, the groups previously fed the seeds were switched to standard food for 1 month (wash-out). All animals were submitted to a neurological examination and observed in an open-field situation before, during the diet (at 4 and 8 months), and finally after wash-out. Neither LS-fed rats nor controls ever showed neurological deficits. By contrast, in an open-field the activity was significantly increased in the LS-eating rats at both the 4th and 8th month. The effect was indeed reversible, since it disappeared after the wash-out. It is suggested that the enhanced open-field activity seen in the LS group might indicate a reversible excitable status. However, there is no evidence at present that the behavioral changes described represent a marker of neurodegeneration in this animal species.

Abstract
The present study was undertaken in order to establish the possible involvement of GABAergic and/or opioid pathways in the mechanism underlying the arginine-vasopressin (AVP) response to physical exercise. After fasting overnight, seven subjects were tested on four mornings at least 1 week apart. Exercise was performed on a bicycle ergometer. The workload was gradually increased at 3 min intervals until exhaustion and lasted about 15 min in all subjects. Tests were carried out under administration of placebo, the opioid antagonist naloxone (10 mg as an i.v. bolus injection), the GABAergic agonist sodium valproate (600 mg in three divided doses orally) or naloxone plus sodium valproate. Plasma AVP levels rose 4-fold during exercise. The administration of naloxone did not modify, whereas sodium valproate completely abolished the plasma AVP rise during exercise. When naloxone was given together with sodium valproate, AVP rose 3-fold in response to exercise. These data suggest the involvement of a GABAergic mechanism in regulation of the AVP response to physical exercise in men. Furthermore, the data argue against a role of naloxone sensitive endogenous opioids in the control of AVP during exercise, whereas they suggest a partial opioid mediation of the GABAergic inhibitory action.

Abstract
Locally advanced rectal cancer has been a surgical challenge because of fixation of the primary tumor to the boney pelvis or to other pelvic soft tissues. During a 12-month period seven patients with locally advanced adenocarcinoma of the rectum were treated preoperatively with simultaneous pelvic irradiation (4500-5040 cGy) and infusion chemotherapy (5-fluorouracil 1000 mg per m2 per day over 96 hours and mitomycin 10 mg per m2. Tolerance was reasonable and all patients underwent successful resection of the primary lesion. Two patients had a complete response to preoperative combined modality therapy with no cancer found in the surgical specimen. With a short follow-up period, all patients have experienced satisfactory healing and none have suffered local or distant recurrence. The results of this limited series are encouraging for future clinical trials.
