Impact of Pre-Liver Transplant Treatments on the Imaging Accuracy of HCC Staging and Their Influence on Outcomes.

The outcome of liver transplantation (LT) for hepatocarcinoma (HCC) is strongly influenced by HCC staging, which is based on radiological examinations in a pre-LT setting; concordance between pre-LT radiological and definitive pathological staging remains controversial. To address this issue, we retrospectively analyzed our LT series to assess concordance between radiology and pathology and to explore the factors associated with poor concordance and outcomes. We included all LTs with an HCC diagnosis performed between 2013 and 2018. Concordance (Co group) was defined as a comparable tumor burden in preoperative imaging and post-transplant pathology; otherwise, non-concordance was diagnosed (nCo group). Concordance between radiology and pathology was observed in 32/134 patients (Co group, 24%). The number and diameter of the nodules were higher when nCo was diagnosed, as was the number of pre-LT treatments. Although concordance did not affect survival, more than three pre-LT treatments led to a lower disease-free survival. Patients who met the Milan Criteria (Milan-in patients) were more likely to receive ≥three prior treatments, leading to a lower survival in multi-treated Milan-in patients than in other Milan-in patients. In conclusion, the concordance rate between the pre-LT imaging and histopathological results was low in patients with a high number of nodules. Multiple bridging therapies reduce the accuracy of pre-LT imaging in predicting HCC stages and negatively affect outcomes after LT.

[Identifying population needs: methods of analysis and stratification]. / Identificare i bisogni della popolazione: metodi di analisi e di stratificazione.

. Identifying population needs: methods of analysis and stratification. In this article, examples of population stratification models used at the national level to identify different levels of needs and interventions are reported. Most models are based primarily on health data, diseases, clinical complexity, use of health services, hospitalizations, emergency room access, pharmaceutical prescriptions, and exemption codes. The limitations of these models relate to the availability and integration of data, as well as generalizability in different contexts. Moreover, to address the difficulty of implementing effective local interventions, the co-production or integration of social and health services is strongly suggested. Some survey techniques are presented to detect the needs, expectations, and resources of specific communities or populations.

Endotypes of Nasal Polyps in Children: A Multidisciplinary Approach.

Nasal polyps (NPs) are rarely reported in childhood and usually represent red flags for systemic diseases, such as cystic fibrosis (CF), primary ciliary dyskinesia (PCD) and immunodeficiencies. The European Position Paper released in 2020 (EPOS 2020) provided a detailed classification and defined the correct diagnostic and therapeutic approaches. We report a one-year experience of a multidisciplinary team, made up of otorhinolaryngologists, allergists, pediatricians, pneumologists and geneticists, with the aim of ensuring a personalized diagnostic and therapeutic management of the pathology. In 16 months of activity, 53 patients were admitted (25 children with chronic rhinosinusitis with polyposis and 28 with antro-choanal polyp). All patients underwent phenotypic and endo-typic assessment, using proper classification tools for nasal pathology (both endoscopic and radiological), as well as adequate cytological definition. An immuno-allergic evaluation was carried out. Pneumologists evaluated any lower airway respiratory disease. Genetic investigations concluded the diagnostic investigation. Our experience enhanced the complexity of children's NPs. A multidisciplinary assessment is mandatory for a targeted diagnostic and therapeutic pathway.

Juvenile psammomatoid ossifying fibroma of the ethmoid sinus successfully treated by endoscopic sinus surgery: a case report.

Background: Juvenile ossifying fibromas (JOF) are benign osteofibrous tumors very rarely located in paranasal sinus. The diagnostic and therapeutic tools applied in sinonasal inflammatory pathologies and other tumors fail to address a specific management in this rare pathology. Currently, the only available treatment is surgery. Endoscopic sinus surgery (ESS) allows a complete but minimally invasive approach compared to the open technique, especially for the minor demolition on growing bone structures. Case Description: We describe a case of a 13-year-old boy presenting in the Emergency Department for a head trauma. The computerized tomography (CT) revealed an ethmoid-maxillary bony mass suspected to be a juvenile ossifying fibroma. The patient underwent ESS. Histological examination confirmed a juvenil psammomatoid ossifyng fibroma (JPOF). A revision surgery with the same technique was required after 7 months due to relapse of the tumor. He did not develop postoperative complications. The 3-years follow-up did not show any signs of relapse. Conclusions: Paranasal JOF is a challenge for the ear-nose-throat (ENT) surgeon. The principles of local disease control for relapse reduction are different from inflammatory diseases and other paranasal tumors. Severe organ damage and recurrences are possible if caution is not observed. Specific guidelines about management are required on the basis of the shared experiences in the few cases reported in literature.

High-dose glucocorticoids pulse-therapy for beta-coronaviridae pneumonia: a systematic literature review and case-series of Coronavirus disease-2019.

OBJECTIVES: The results of the RECOVERY trial identified dexamethasone as the first pharmacological therapy that reduces mortality in patients with COVID-19. The aim of this paper is to conduct a systematic literature review on safety and efficacy of pulse glucocorticoid therapy for Severe Acute Respiratory Syndrome (SARS)-CoronaVirus (CoV), Middle East Respiratory Syndrome (MERS)-CoV or SARS-CoV-2 infections and describe a case-series of COVID-19 patients treated with off-label pulse doses of methylprednisolone. METHODS: We performed a systematic literature review on safety and efficacy of pulse therapy for betacoronaviridae infections as described in the protocol registered on PROSPERO (CRD42020190183). All consecutive patients admitted to Arcispedale Santa Maria Nuova di Reggio Emilia or Guastalla Hospital with COVID-19 between March 1st and April 30th, 2020 and treated with methylprednisolone 1 gram/day for at least three days were included in the case series. A retrospective review of available computed tomography (CT) scan and chest x-ray was performed independently by two radiologists blinded to clinical data, and discordances were resolved by consensus. RESULTS: Twenty papers were included for SARS, but only two were comparative and were included in the primary endpoint analysis. Likewise, eleven papers were included for COVID-19, four of which were comparative and were considered for the primary outcome analysis. Included studies for both SARS and COVID-19 are mostly retrospective and highly heterogeneous, with lethality ranging from 0% to 100% and ICU admission rate ranging from 9% to 100%. Fourteen patients were included in our case series, 7 males and 7 females. CONCLUSIONS: No randomised controlled trial is available yet for corticosteroids pulse-therapy defined as at least ≥500mg/day methylprednisolone in patients with emerging coronavirus pneumonia. Lethality among our cohort is high (4/14), but this finding should be interpreted with caution due to the fact that in our setting pulse-steroids were used in patients not eligible for other treatments because of comorbidities or as rescue therapy. The incidence of steroid-related adverse events seems low in our cohort. The quality of the evidence on glucocorticoid pulse-therapy in SARS, MERS and COVID-19 is poor. Randomised controlled trials are greatly needed.

Abdominal Visceral Infarction in 3 Patients with COVID-19.

A high incidence of thrombotic events has been reported in patients with coronavirus disease (COVID-19), which is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. We report 3 clinical cases of patients in Italy with COVID-19 who developed abdominal viscera infarction, demonstrated by computed tomography.

Robotic surgery vs laparoscopic surgery in patients with diagnosis of endometriosis: a systematic review and meta-analysis.

Endometriosis is one of the most common medical conditions affecting the women. The study aimed to evaluate the safety and efficacy of robotic-assisted laparoscopic surgery (RAS) versus conventional laparoscopic surgery (LPS) in the treatment of endometriosis. PubMed, Embase, Cochrane and CINAHL databases were searched from January 1995 to March 2019. According to meta-analysis criteria, five comparative studies were selected. A total of 1527 patients were identified. In the meta-analysis, there were no significant differences in blood loss, complication, and hospital stay between RAS and LPS surgeries in the treatment of patients with endometriosis. However, RAS surgery required a higher weighted mean operating time than LPS surgery, 0.54 (95% confidence interval; 0.37 to 0.70; p < 0.00001) min. This meta-analysis confirmed that the robotic surgery is safe and feasible in patients affected by endometriosis. We could suggest that RAS is a valid option and might be considered an alternative to LPS especially in advanced cases.

Pilot study to explore the prophylactic efficacy of oral probiotic Streptococcus salivarius K12 in preventing recurrent pharyngo-tonsillar episodes in pediatric patients.

Background: In the pediatric population, acute pharyngo-tonsillitis represents one of the most frequent causes of access to outpatient treatment and use of antibiotics. In frequent tonsillitis, the pharmacological approach is no longer effective, and, therefore, surgery becomes the treatment of choice. Methods: This study compares the prophylactic efficacy of Streptococcus salivarius K12 (Bactoblis®) in children with recurrent pharyngo-tonsillitis treated vs untreated, with a 12 -month follow-up. The primary objectives are: The incidence of recurrence of pharyngo-tonsillar episodes and the concomitant use of other drugs. Secondary objectives are: tolerability of the treatment, the effectiveness in terms of clinical improvement, days of absence from school, reduction of the use of standard therapies, and cancellation from the surgical planning list. Results: Patients belonging to group A (treated with K12 for 90 days) were 24 males and 26 females, mean age 6.6 years (SD=1.57), those belonging to group B (untreated) were 23 males and 27 females, average age 6.8 years (SD=1.72). In the follow-up, group A reported 26 inflammatory pharyngo-tonsillary episodes in the first trimester, unlike group B, who reported 72 in the second trimester. This has shown a lower incidence (3.38%) of the disease compared to group B (6.66%), for a total of 169 inflammatory pharyngo-tonsillary episodes in group A against 333 in group B. A reduction in days of school absence of 429 days in group A and 927 days in the control group (P<0.01) was also noted. Finally, 14 children of group A (28%) underwent adenotonsillectomy, against the whole group B. No adverse events were reported. Conclusion: The efficacy of K12 on the prevention of pharyngo-tonsillar infections, the decrease in the use of antibiotics and the improvement of the overall quality-of-life was confirmed, with a decreased number of absences from school and fewer patients undergoing surgery.

Antiviral treatment and virological monitoring of oseltamivir-resistant influenza virus A(H1N1)pdm09 in a patient with chronic B lymphocytic leukemia.

We report the virological monitoring and the antiviral therapy adopted for the treatment of a patient affected by chronic B lymphocytic leukemia, who experienced a severe pneumonia with long-term shedding of influenza virus A(H1N1)pdm09, characterized by an early development of oseltamivir resistance.

Plasmodium knowlesi malaria in a traveller returning from the Philippines to Italy, 2016.

Plasmodium knowlesi is a simian parasite responsible for most human cases of malaria in Malaysian Borneo. A timely recognition of infection is crucial because of the risk of severe disease due to the rapid increase in parasitemia. We report a case of P. knowlesi infection in a traveller who developed fever and thrombocytopenia after returning from the Philippines in 2016. Rapid antigen test was negative, microscopy examination showed parasites similar to Plasmodium malariae, with a parasite count of 10,000 parasites per µL blood, while molecular testing identified P. knowlesi infection. Treatment with atovaquone-proguanil led to resolution of fever and restoration of platelet count in two days. P. knowlesi infection should be suspected in febrile travellers returning from South East Asia. Due to the low sensitivity of rapid antigen tests and the low specificity of microscopy, confirmation by molecular tests is recommended.

Comparing imported malaria in adults and children presenting to an Italian teaching hospital: A 10-year retrospective study.

BACKGROUND: Malaria is not endemic in Italy, but it still represents an important threat to the travelers' health. With this study we wanted to compare the characteristics of imported malaria between adults and children. METHOD: This retrospective observational study includes all patients admitted to the Infectious Diseases Unit and in the Pediatric Department of Padua (Italy), and discharged with a diagnosis of malaria from 2005 to 2015. The variables considered are epidemiological and clinical. RESULTS: 172 cases of imported malaria were studied (124 adults and 48 children), P. falciparum was responsible for 90,7% of the cases, and was contracted mostly in Africa (96,5%), especially by foreigners visiting friends and relatives (VFR). Chemoprophylaxis was adopted only by few patients. 93% of all the patients developed the uncomplicated malaria, but pediatric patients had severe malaria significantly more often than adults (OR = 4,06, p = 0,015). Children also had significantly lower hemoglobin levels and higher parasitemia. The drugs used to treat the two groups were substantially different, but both had a good overall outcome. CONCLUSIONS: In order to reduce the risk of imported malaria, educational actions should target potential VFR travelers, and they should underline the different risk of severe malaria in adults and children. A further implementation of the recommended therapies could improve the patients' outcome.

Vibrio cholerae non-O1, non-O139 bacteraemia associated with pneumonia, Italy 2016.

This paper describes an elderly male patient, living in the Veneto Region, Italy, who developed Vibrio cholerae bacteraemia and pneumonia. Some days previously, while on holiday in the Lagoon of Venice, he had been collecting clams in seawater, during which he suffered small abrasions of the skin. On admission to hospital, he was confused, had fever and a cough, but neither diarrhoea nor signs of gastroenteritis were found. Both blood and stool cultures grew V. cholerae of non-O1 non-O-139 type, and the patient recovered after prompt administration of intravenous ceftriaxone for 2 weeks. This clinical case emphasises the role of global warming and climate changes in causing increasing numbers of water-borne infections.

Contrast-enhanced ultrasound (CEUS) appearance of hepatic myelolipoma.

The case report is a description of a single case of hepatic myelolipoma, a very rare benign hepatic tumor, evaluated with contrast sonography, in a 72-year-old female. It was previously reported as hyperechoic lesions at sonography. CEUS features of the lesion were: homogeneous hyperenhancement in the arterial phase and a slight hyperenhancement in the portal venous phase typical of benign tumors. The case report shows CEUS may help in differential diagnosis between benign and malignant lesions, but only the biopsy of the tumor and the pathological evaluation allows the diagnosis.

Myo-inositol modulates insulin and luteinizing hormone secretion in normal weight patients with polycystic ovary syndrome.

AIM: To investigate hormonal dynamics in a group of non-obese polycystic ovary syndrome (PCOS) patients under myo-inositol (MYO) administration. METHODS: Hormonal profiles, insulin response to oral glucose tolerance test (OGTT) and luteinizing hormone (LH) response to gonadotropin-releasing hormone (GnRH) stimulation test before and after the administration of a preparation of MYO (3 g p.o. daily) mixed with lactoferrin and bromelin, in a group (n = 24) of normal weight PCOS patients. RESULTS: After the treatment interval, body mass index (BMI) did not change while LH, LH/follicle-stimulating hormone, 17-hydroxy-progesterone and androstenedione decreased significantly. Insulin response to OGTT was significantly reduced after the treatment interval (P < 0.05) as well as GnRH-induced LH response (P < 0.05). High-sensitivity C-reactive protein decreased significantly after the treatment interval. CONCLUSION: MYO administration positively modulates insulin sensitivity in non-obese PCOS patients without compensatory hyperinsulinemia, improving hormonal parameters. The presence of bromelin in the formulation modulated the pro-inflammatory state that characterizes PCOS, independently of BMI.

Modulatory role of D-chiro-inositol (DCI) on LH and insulin secretion in obese PCOS patients.

Polycystic ovary syndrome (PCOS) is a common endocrine condition that affects fertility through oligo-ovulation, hyperandrogenism and polycystic morphology of the ovaries. Since it has been demonstrated a high incidence of insulin resistance in PCOS patients, our study aimed to evaluate the efficacy of the integrative treatment with D-chiro-inositol (DCI) (500 mg die, per os, for 12 weeks) on hormonal parameters and insulin sensitivity in a group of overweight/obese PCOS patients (body mass index; BMI > 26). After the treatment, interval several endocrine parameters improved (luteinizing hormone [LH], LH/follicle stimulating hormone [FSH], androstenedione and insulin), insulin response to oral glucose tolerance test reported the significant improvement of insulin sensitivity as well as the gonadotropin-releasing hormone (GnRH)-induced (10 µg, in bolus) LH response. BMI decreased, though no lifestyle modification was requested. When data were analyzed according to the presence or absence of first-grade diabetic relatives, PCOS patients with diabetic relatives showed greater improvement after DCI administration. In conclusion DCI administration is effective in restoring better insulin sensitivity and an improved hormonal pattern in obese hyperinsulinemic PCOS patients, in particular, in hyperinsulinemic PCOS patients who have diabetic relatives.

Preoperative assessment of HER-2/neu status in breast carcinoma: the role of quantitative real-time PCR on core-biopsy specimens.

OBJECTIVES: Knowledge of HER-2/neu status is mandatory to identify breast cancer patients amenable to trastuzumab treatment. We evaluated the diagnostic performance of quantitative real-time polymerase chain reaction (qRT-PCR) in the preoperative determination of HER-2/neu status in breast cancer, using core biopsy material. METHODS: In a prospective series, qRT-PCR was performed on fresh core biopsy specimens taken preoperatively in 87 patients with breast carcinoma. Cases with qRT-PCR ratio > or = 2.0 were considered to have HER-2/neu amplification. The results of RT-PCR analysis were compared with those of the standard immunohistochemistry (IHC) and Fluorescence in situ hybridization (FISH) methods. Cases with IHC 3+ or with IHC 2+ and FISH showing amplification were considered HER-2/neu positive. All other cases were considered HER-2/neu negative. RESULTS: qRT-PCR showed HER-2/neu amplification in 13 cases (14.9%), while the standard IHC-FISH combined approach identified 17 HER-2/neu-positive cases (19.5%). Overall, there was concordance between methods in 83 of 87 patients (95.4%). The Spearman's rho correlation coefficient was 0.851; p<0.001. The diagnostic performance for preoperative diagnosis of HER-2/neu status using RT-PCR on core biopsy specimens as compared to standard approach was as follows: sensitivity 76.5%; specificity 100%; positive predictive value 100%; negative predictive value 94.6%. CONCLUSIONS: Quantitative RT-PCR determination of HER-2/neu status from core biopsy specimens provided results comparable to those given by the standard IHC and FISH methods. The use of qRT-PCR on core biopsy material may represent a very useful and easy tool to enhance early identification of HER-2/neu-positive breast cancer patients who, possibly can benefit from trastuzumab treatment.

Predicting the status of axillary lymph nodes in breast cancer: a multiparameter approach including axillary ultrasound scanning.

In a prospective study, we attempted to predict axillary metastases in 135 breast cancer patients by a preoperative multiparameter evaluation including axillary ultrasound scanning (US). After surgery, factors associated with lymph node metastases by univariate analysis were included in a multivariate model. By multivariate analysis, the stronger independent predictors of lymph node metastases were suspicious axillary US (p<0.001), tumor location in the outer quadrants (p=0.001) and high Ki-67 index (>10%) (p=0.002). A predictive model based on these variables, identified a high-risk group (20.0%) represented by women with suspicious axillary US, tumor in the outer quadrants and high Ki-67 index, with axillary metastases in 100%, whereas all patients with opposite features (8.1%) had uninvolved axillary lymph nodes. This multiparameter evaluation including axillary US may be used to optimize the selection of breast cancer patients candidate to sentinel lymph node biopsy or axillary lymph node dissection. The accuracy of this predictive model still requires prospective validation in a larger sample of women.
