Surgical treatment of a rare case of bilateral ptosis due to localized ocular amyloidosis

We describe a rare case of a 31-year old woman with bilateral ptosis due to localized amyloidosis. She referred a nine-year history of ptosis and surgical treatment with frontalis suspension three years previously. Following complete ophthalmological examination and evaluation of the ptosis we carried out tarsal and fornix biopsy, which revealed accumulation of a weakly eosinophilic amyloid positive substance. We performed surgical correction using the levator aponeurosis–Müller’s muscle complex re-adaptation technique and amyloid substance debulking in all the palpebral layers in the left eye. The material obtained was stained with hematoxylin–eosin, Congo Red, PAS and alpha-actin, which confirmed amyloid deposition. Successively, the right eye was operated in the same manner and entropion was managed by dissection and removal of amyloid from subconjunctival layers. Five years following surgery, the corrective procedure for ptosis was still effective. Surgical treatment of ptosis is very complex and requires precise indications. Appropriate management depends on the etiopathogenesis, accurate diagnosis, and clinical findings

Distinctive diffusive properties of swimming planktonic copepods in different environmental conditions

Suspensions of small planktonic copepods represent a special category in the realm of active matter, as their size falls within the range of colloids, while their motion is so complex that it cannot be rationalized according to basic models of self-propelled particles. Indeed, the wide range of individual variability and swimming patterns resemble the behaviour of much larger animals. By analysing hundreds of three-dimensional trajectories of the planktonic copepod Clausocalanus furcatus, we investigate the possibility of detecting how the motion of this species is affected by different external conditions, such as the presence of food and the effect of gravity. While this goal is hardly achievable by direct inspection of single organism trajectories, we show that this is possible by focussing on simple average metrics commonly used to characterize colloidal suspensions, such as the mean square displacement and the dynamic correlation functions. We find that the presence of food leads to the onset of a clear localization that separates a short-time ballistic from a long-time diffusive regime. Such a benchmark reflects the tendency of C. furcatus to remain temporally feeding in a limited space and disappears when food is absent. Localization is clearly evident in the horizontal plane, but is negligible in the vertical direction, due to the effect of gravity. Our results suggest that simple average descriptors may provide concise and useful information on the swimming properties of planktonic copepods, even though single organism behaviour is strongly heterogeneous

Approccio chirurgico e indicazioni ai trattamenti estetici nel dismorfismo da eccesso

Introduction. Patients with body dysmorphic disorder often go to the plastic surgeon to correct what they consider a physical deformity or defect, although their appearance falls within normal aesthetic standards. The aim of our study was to evaluate the real need for aesthetic treatments in such patients. Patients and methods. We included patients who practised an intense sport activity and believed they had body deformities ascribable to their sport activity. We evaluated whether the deformities described by the patients were real or exaggerated. The patients who did have a deformity underwent surgery to correct it; their level of satisfaction was evaluated at a 6-month follow-up examination. The patients with subjective deformities underwent a psychiatric examination. Results. We enrolled 51 patients who practised an intense sport activity and reported body deformities. Forty-one of these patients were found to have a body deformity upon examination and underwent surgery. Surgery was considered to be unnecessary in the remaining 10 patients. Thirty-two of the 41 patients who did undergo were highly satisfied with the outcome. Discussion. The plastic surgeon often sees patients with minor body deformities that do not require treatment but are a major cause of psychological disorders. A thorough psychiatric examination is necessary in such patients to rule out psychiatric diseases. The plastic surgeon should make every effort to identify patients with subjective body dysmorphic disorder to avoid the negative consequences due to the patient’s insatisfaction for the outcome of surgery

Trattamento della contrattura capsulare da impianto protesico mammario. Nostra esperienza

La più comune complicanza in pazienti sottoposte ad intervento chirurgico di impianto protesico mammario è la contrattura capsulare. Non esiste, attualmente, un trattamento standard efficace per questa complicanza. Lo scopo del presente articolo è illustrare la nostra esperienza sull’uso degli antagosisti dei recettori per i leucotrieni nel trattamento della contrattura capsulare. I risultati mostrano che l’utilizzo di questi farmaci è in grado di ridurre il dolore e la distorsione della mammella in pazienti con un lungo decorso di contrattura capsulare

food quality effects on health and sustainability today a model case report

AbstractThe Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico is a five-century institution that, besides the unique clinical role in the center of Milan, may rely on benefactor donations such as fields and farming houses not far from the city, for a total of 8500 ha, all managed by the "Sviluppo Ca' Granda' Foundation". Presently, the main products of these fields are represented by rice and cow's milk. During the latest years, farmers and managers have developed a model of sustainable food production, with great attention to the product quality based on compositional analysis and functional nutritional characteristics. This experience represents a new holistic model of food production and consumption, taking great care of both sustainability and health

Long-term survival of methotrexate in psoriatic arthritis

Objective. The purpose of this study was to evaluate the long-term survival rate of Methotrexate (MTX) in the peripheral joint involvement of psoriatic arthritis (PsA) in a setting of everyday clinical practice. Methods. This was an observational restrospective study performed using the data from a dermatological-rheumatological PsA clinic. All of the patients evaluated at this clinic from March 1997 to December 2007 who were started on MTX alone, had a three-year follow-up time or had discontinued the therapy were included into the survey. Results. Of the 174 evaluable patients, 104 (59.8%) were still taking MTX after three years of treament. The reasons of therapy discontinuation in the remaining 70 (40.2%) patients were: 34 (19.5%) lost-to-follow-up, 18 (10.3%) adverse events, 14 (8%) inefficacies, and 4 (2.3%) deaths (none related to the therapy). MTX was effective in controlling joint inflammation but not in preventing their deterioration. Overall, adverse events were recorded in 43 patients (36.4% of the 114 patients with a three-year follow-up). No serious side effect occurred in the study population. Conclusions. The results of this study showed that, in a setting of clinical pratice, MTX had a good three-year performance in patients with peripheral PsA. Almost 60% of them were still taking this drug at the end of the study period and the toxicity was more than acceptable. In our opinion, MTX might be considered the non-biological DMARD of choice for the treatment of this condition. However it should be used earlier and at higher doses

Evidence of dynamical dipole excitation in the fusion-evaporation of the 40Ca +152Sm heavy system

The excitation of the dynamical dipole mode along the fusion path was investigated for the first time in the formation of a heavy compound nucleus in the A ∼ 190 mass region. The compound nucleus was formed at identical conditions of excitation energy and spin from two entrance channels: the charge-asymmetric 40 Ca + 152 Sm and the nearly charge-symmetric 48 Ca + 144 Sm at E lab = 11 and 10.1 MeV / nucleon, respectively. High-energy γ rays and light charged particles were measured in coincidence with evaporation residues by means of the MEDEA multidetector array (Laboratori Nazionali del Sud, Italy) coupled to four parallel plate avalanche counters. The charged particle multiplicity spectra and angular distributions were used to pin down the average excitation energy, the average mass, and the average charge of the compound nucleus. The γ -ray multiplicity spectrum and angular distribution related to the nearly charge-symmetric channel were employed to obtain new data on the giant dipole resonance in the compound nucleus. The dynamical dipole mode excitation in the charge-asymmetric channel was evidenced, in a model-independent way, by comparing the γ -ray multiplicity spectra and angular distributions of the two entrance channels with each other. Calculations of the dynamical dipole mode in the 40 Ca + 152 Sm channel, based on a collective bremsstrahlung analysis of the reaction dynamics, are presented. Possible interesting implications in the superheavy-element quest are discussed
