Should the host reaction to anisakiasis influence the treatment? Different clinical presentations in two cases

Gastrointestinal anisakiasis is a parasitic infection occurring in people that consume raw or inadequately cooked fish or squid. It is frequently characterized by severe epigastric pain, nausea and vom iting caused by the penetration of the larvae into the gastric wall. Acute gastric anisakiasis with severe chest discomfort is rarely report ed in Italy. On the other hand, gastro-allergic anisakiasis with rash, urticaria and isolated angioedema or anaphylaxis is a clinical entity that has been described only recently. Also, if patients usually develop symptoms within 12 hours after raw seafood ingestion, not always endoscopic exploration can promptly identify the Anisakis larvae. Moreover, some authors consider the prevailing allergic reaction as a natural and effective defense against the parasitic attack. We report two cases of peculiar manifestations of anisakiasis in both acute and chronic forms (severe chest discomfort and anaphylactoid reaction)

Deregulated expression of aurora kinases is not a prognostic biomarker in papillary thyroid cancer patients.

Abstract A number of reports indicated that Aurora-A or Aurora-B overexpression represented a negative prognostic factor in several human malignancies. In thyroid cancer tissues a deregulated expression of Aurora kinases has been also demonstrated, butno information regarding its possible prognostic role in differentiated thyroid cancer is available. Here, weevaluated Aurora-A and Aurora-B mRNA expression and its prognostic relevance in a series of 87 papillary thyroid cancers (PTC), with a median follow-up of 63 months. The analysis of Aurora-A and Aurora-B mRNA levels in PTC tissues, compared to normal matched tissues, revealed that their expression was either up-or down-regulatedin the majority of cancer tissues. In particular, Aurora-A and Aurora-B mRNA levels were altered, respectively, in 55 (63.2%) and 79 (90.8%) out of the 87 PTC analyzed. A significant positive correlation between Aurora-A and Aurora-B mRNAswas observed (p=0.001). The expression of both Aurora genes was not affected by the BRAF(V600E) mutation. Univariate, multivariate and Kaplan-Mayer analyses documented the lack of association between Aurora-A or Aurora-B expression and clinicopathological parameterssuch as gender, age, tumor size, histology, TNM stage, lymph node metastasis and BRAF status as well asdisease recurrences or disease-free interval. Only Aurora-B mRNA was significantly higher in T(3-4) tissues, with respect to T(1-2) PTC tissues. The data reported here demonstrate that the expression of Aurora kinases is deregulated in the majority of PTC tissues, likely contributing to PTC progression. However, differently from other human solid cancers, detection of Aurora-A or Aurora-B mRNAs is not a prognostic biomarker inPTC patients

Arthroscopic treatment of an unusual distal clavicle ostheochondroma causing rotator cuff impingement: Case report and literature review

Chronic shoulder impingement is one of the most common causes of shoulder pain. Intrinsic, extrinsic and secondary factors play a role in this syndrome; however the etiology of the pathology is still under debate. In rare cases, it can be caused by tumors, such as an osteochondroma. In the present study, a 49-year-old patient presented with shoulder pain for 6 months. Initially he underwent conservative treatment, without relief of symptoms. X-rays and MRI were then performed and showed the presence of an exostotic formation on the undersurface of the lateral third of the clavicle. The formation was arthroscopically removed. Histologic examination confirmed the diagnosis of osteochondroma. After surgery, the patient resumed fully activities with no symptoms within 3 months. At 1 year follow up, there are still no clinical or radiological signs of recurrence. This is, to our knowledge, the first case where an arthroscopic approach was used to remove an ostochondroma of the distal third of the clavicle

Sarcopenic obesity research perspectives outlined by the sarcopenic obesity global leadership initiative (SOGLI) – Proceedings from the SOGLI consortium meeting in rome November 2022

The European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO) launched the Sarcopenic Obesity Global Leadership Initiative (SOGLI) to reach expert consensus on a definition and diagnostic criteria for Sarcopenic Obesity (SO). The present paper describes the proceeding of the Sarcopenic Obesity Global Leadership Initiative (SOGLI) meeting that was held on November 25th and 26th, 2022 in Rome, Italy. This consortium involved the participation of 50 researchers from different geographic regions and countries. The document outlines an agenda advocated by the SOGLI expert panel regarding the pathophysiology, screening, diagnosis, staging and treatment of SO that needs to be prioritized for future research in the field

The promotional functionality of evaluative language in tourism discourse

This study intends to investigate the use of evaluation in a corpus of British tourist brochures produced by tour operators specializing in the promotion of Italy. The theoretical framework is the Appraisal System developed mainly by White (1998, 2001) and Martin (2000) in order to study the discourse functions of evaluative resources. The creators of brochures resort mainly to two categories of Appraisal. The first concerns the expression of emotions (Affect), both in an implicit and explicit way, while the second category (Appreciation) includes aesthetic assessments. Evaluation can be amplified by several linguistic devices which either sharpen the margins of an experiential category or intensify the meaning of a word, like those lexical items which include an assessment of intensity as part of their semantic load. The iteration of evalua­tive meanings constructs a prosody, bringing an emotional and aesthetic colour to the whole text which in­volves the reader and increases the perceived value of a tourist destination.<br/

Characterization of a calmodulin-dependent high-affinity cyclic AMP and cyclic GMP phosphodiesterase from male mouse germ cells.

Two cyclic nucleotide phosphodiesterase activities were separated by ion-exchange chromatography of cytosol from male mouse germ cells. A form eluted at low salt concentration showed high affinity (Km congruent to 2 microM) and low affinity (Km congruent to 20 microM) for cyclic AMP, and high affinity (Km congruent to 3.5 microM) for cyclic GMP. A second form, eluted at high salt concentration, showed high affinity (Km congruent to 5 microM) for cyclic AMP and was similar to a phosphodiesterase activity described in rat germ cells. The present study was performed to characterize the first form, which represents most of the phosphodiesterase activity in mouse germ cells. The enzyme was sensitive to Ca2+ and calmodulin stimulation, which increased its activity 3-4-fold. Calmodulin stimulation depended on direct interaction of the activator with the enzyme, as indicated by the reversible changes in the chromatographic elution pattern in the presence of Ca2+, as well as by the increase in the sedimentation coefficient in the presence of calmodulin. Reciprocal inhibition kinetics between cyclic AMP and cyclic GMP for the calmodulin-dependent form demonstrated a non-competitive inhibition between the two substrates, suggesting the presence of separate catalytic sites. This is in agreement with kinetic parameters and different thermal stabilities of cyclic AMP- and cyclic GMP-hydrolysing activities. Furthermore, the relevant change in s value, depending on the absence or presence of Ca2+ and calmodulin, suggested that the enzyme is composed of subunits, which aggregate in the presence of the activator. A model for catalytic site composition and reciprocal interaction is also proposed
