RESUMO

Cardiac tumors, due to the various clinical scenarios and their histological subtypes, are still challenging for clinicians. They are differentiated into primary and secondary. The latest are more common and are usually lung and breast cancers, melanomas, and lymphoma metastasis. We present a case of a 73-year-old woman, with a history of breast cancer 10 years earlier, admitted to Cath lab for an elevation of the ST-segment of the electrocardiogram, myocardial infarction. Echocardiogram showed a curious abnormality in the myocardial wall. Thanks to a multimodality imaging strategy, including contrast-enhanced echocardiography and cardiac magnetic resonance, characterization of the underlying pathology was clear and, thus, the appropriate management and therapy.


This is the case of a cardiac metastatic tumor, whose certain diagnosis can only be made by myocardial biopsy ­ an invasive sample of heart tissue ­ unfortunately not available in our case. Alternatively, we puzzled data from two second-level imaging techniques: contrast-enhanced cardiac ultrasound and cardiac magnetic resonance, which allowed us to better evaluate the nature of this cardiac mass. The former gave information about its blood supply, the latter gave information about tissue characterization. In this paper, we show how a complete integration of data from clinical and a stepwise multimodality imaging-based approach may allow a diagnosis in a complex clinical case.

RESUMO

This report describes the case of a 56-year-old woman who presented at the emergency room with a 3-week history of severe, intermittent abdominal pain. A CT scan revealed colo-colic intussusception caused by a large, substenosing mass with predominant adipose density. Subsequent endoscopic examination with biopsy revealed a necrotic tissue covering the mass, without definitive histological characterization. A second biopsy led to the extremely rare diagnosis of colo-colic lipoma. While intussusception is rare in adults, it's important to consider it as a differential diagnosis, especially when presenting with abdominal pain and signs of bowel obstruction. Timely diagnosis and appropriate treatment are essential to prevent complications.

RESUMO

We describe a case of a 65-year-old woman affected by hemangiopericytoma/solitary fibrous tumor of the right shoulder-subclavian region. Hemangiopericytoma/solitary fibrous tumor is a rare tumor of uncertain malignancy. She reports shoulder pain and inability to abduct the arm and elevate the shoulder. Imaging showed erosion of the scapula. The patient underwent 5 sessions of "on demand" embolization in the previous 2 years scheduled for recurrence of symptoms-swelling of tissues. Further 2 treatments were achieved through embolization via 2 different microballoon catheter combined with percutaneous cryoablation with 5 probes. Images after the treatment demonstrate a marked reduction in the hypervascularized area and an increase in the necrosis area. So, this combined treatment is safety and reproducible also in extrahepatic tissue.

RESUMO

There is an increasing awareness on the association between mitral valve prolapse (MVP) and sudden cardiac death. Mitral annular disjunction (MAD) is a phenotypic risk feature that can help in risk stratification. We present a case of a 58-year-old woman who experienced an out-of-hospital cardiac arrest caused by ventricular fibrillation interrupted by a direct current shock. No coronary lesions were documented. Echocardiogram showed myxomatous MVP. Nonsustained ventricular tachycardia have been registered during hospital stay. Interestingly, cardiac magnetic resonance revealed MAD and a late gadolinium enhancement area in inferior wall. Finally, a defibrillator has been implanted. For arrhythmic risk stratification of MVP with MAD, multimodality imaging is the diagnostic tool to find out the disease behind many cardiac arrests of unknown cause.

RESUMO

Background: The effects of sacubitril/valsartan (sac/val) on metabolic parameters and insulin resistance (IR) in non-obese/prediabetic patients have not been previously described. Aim: To evaluate the effects of sac/val on glycemic and metabolic parameters, Homeostatic Model Assessment of IR (HOMA-IR), and echocardiographic parameters in prediabetic patients with heart failure with reduced ejection fraction (HFrEF). Methods: Fifty-nine patients with HFrEF (EF < 35%) but without obesity and/or type 2 diabetes mellitus have been enrolled. All the patients at baseline and week 24 underwent complete anthropometrical evaluation and were subjected to an echocardiogram test. IR has been assessed by HOMA-IR. Results: After 24-week of treatment with sac/val, a significant reduction in fasting plasma glucose (109 ± 9 vs 103 ± 8 mg/dl, p < 0.0001), fasting plasma insulin (16 ± 4 vs 10 ± 4 UI/L), and hemoglobin A1c (HbA1c) value (6% ± 0.5% vs 5.3% ± 0.3%, p < 0.0001) was observed. Similarly, we observed a significant improvement in IR (HOMA-IR, 4.4 ± 0.9 vs 2.5 ± 0.6, p < 0.0001). The echocardiogram evaluation showed a significant reduction of the left ventricular end-diastolic volume (168 ± 24 vs 158 ± 22 ml, p < 0.05), a significant reduction of the left ventricular end-systolic volume (111 ± 26 vs 98 ± 22 ml, p < 0.005), and a significant reduction of E/e' ratio. Sac/val use was also associated with an average 5.1% increase in ejection fraction. Conclusions: Our data seem to indicate that sal/val enhances metabolic control and improves insulin resistance also in prediabetic non-obese patients with HFrEF.

RESUMO

In order to evaluate and identify the antioxidant properties and the phytochemical characteristics, as well as the role of the genetic background and the different fruit parts in the definition of fruit quality, we characterized the existing germplasm through nuclear simple sequence repeats (SSRs) and evaluated the genetic divergence between ancient S. Giovanni varieties (Pyrus communis L.) and different types of grafting in relation to some variables of fruit quality. On the peel and pulp of pear varieties, the contents of flavanols, flavonols, and hydroxycinnamic acids as well as total antioxidant capacity were assessed. Their role in plant defences was confirmed by a significantly higher amount in the peel (206.66 ± 44.27, 48.45 ± 13.65, and 31.11 ± 11.94 mg/100 g, respectively) of S. Giovanni pears than in the pulp (71.45 ± 34.94, 1.62 ± 0.83, and 17.05 ± 5.04 mg/100 g, respectively). Data obtained using capillary analysis of SSR indicate unequivocally that the four samples of San Giovanni varieties can be divided into 3 different genetic groups. Cultivar and the different parts of the fruit can exert an action in the definition of the quality product. The use of local varieties and ecotypes can be considered a valid tool to improve food quality and at the same time to support local agrobiodiversity.

RESUMO

Fatty acids and bioactive lipophilic and hydrophilic compounds (tocopherols, ß-carotene, lutein, squalene, total polyphenols and secoiridoids) in monocultivar Italian extra-virgin olive oil (EVOO) samples produced from the Leccino cultivar and six other yet uncharacterised cultivars (Rustica, Carpinetana, Dritta, Gentile di Chieti and Intosso) were analysed, also taking into account the effect of the type of decanter used for the oil extraction. Significant differences among cultivars were found for α-tocopherol and squalene, but not for carotenoids. Among phenols, cultivars significantly influenced oleuropein and ligstroside aglycones contents, but not those of the dialdehydic form of decarboxymethyl elenolic acid linked neither to tyrosol nor hydroxytyrosol. As previously reported, phenol is quantitatively affected by the type of decanter used for oil extraction. Accordingly, we found that the two-phases decanter preserved in the oil 1.5 times more phenolic compounds as compared with three-phases, whereas it did not influence the amount of lipophilic compounds. Moreover, our data statistically support the finding that type of decanter affects phenols also qualitatively. In fact, the two-phases decanter preferably preserved more the hydroxytyrosol secoiridoid derivatives than the tyrosol ones. Our results from one hand characterise for the first time oils previously unreported, from the other give some new indications on the relative role of factors relevant for the achievement of biologically active extra-virgin oil, i.e. the cultivar and technological ones.
