Inhibition of MMP-2 and MMP-9 by Dietary Antioxidants in THP-1 Macrophages and Sera from Patients with Breast Cancer.

Polyphenols, the main antioxidants of diet, have shown anti-inflammatory, antioxidant and anticarcinogenic activities. Here, we compared the effects of four polyphenolic compounds on ROS production and on the levels of matrix metalloproteinase (MMP)-2 and -9, which represent important pathogenetic factors of breast cancer. THP-1 differentiated macrophages were activated by LPS and simultaneously treated with different doses of a green tea extract (GTE), resveratrol (RSV), curcumin (CRC) and an olive fruit extract (oliplus).

Pulmonary mucoepidermoid carcinoma in a 7-year-old child.

A 7-year-old boy presented with exertional dyspnea and cough, initially misdiagnosed as asthma. Imaging revealed a mass obstructing the left main bronchus, later identified as a pulmonary mucoepidermoid carcinoma (MEC). Following surgical sleeve resection, complete tumor removal occurred without malignancy in surrounding lymph nodes, resulting in symptom resolution without additional therapy.

Lung biopsies in infants and children in critical care situation.

Introduction: Lung biopsy is considered as the last step investigation for diagnosing lung diseases; however, its indication must be carefully balanced with its invasiveness. The present study aims to evaluate the diagnostic yield of lung biopsy in critically ill patients hospitalized in the pediatric intensive care unit (ICU).

Material And Methods: Children who underwent a lung biopsy in the ICU between 1995 and 2022 were included.

Acinar Dysplasia in a Full-Term Newborn with a NKX2.1 Variant.

Acinar dysplasia (AcDys) is one of the three main diffuse developmental disorders of the lung. The transcription factor NK2 homeobox 1 (NKX2.1) partly controls the synthesis of surfactant proteins by type 2 alveolar epithelial cells (AEC2), and germline mutations are known to be associated with brain-lung thyroid syndrome.

The significance of multidisciplinary team meetings in diagnosing and managing childhood interstitial lung disease within the RespiRare network.

Introduction: Childhood Interstitial Lung Disease (chILD) represents a rare and severe group of diseases for which the etiologic workup, classification, and management remain a challenge for most pediatric pulmonologists. In France in 2018, the RespiRare network established the first multidisciplinary team meetings (MDTm) dedicated to chILD. This study aims to investigate the impact of MDTm in chILD diagnosis and management as well as user satisfaction.

Pulmonary cystic echinococcosis in a child.

This case report describes the presentation, diagnosis, and treatment of a 13-year-old boy with pulmonary cystic echinococcosis. The patient presented with low-volume hemoptysis, and lung imaging revealed a large cystic mass, as well as smaller pseudo-nodular lesions, suggesting a large intrathoracic hydatid cyst and ruptured cysts. The diagnosis was confirmed by a positive echinococcosis Western Blot assay, despite equivocal serology.

SARS-CoV-2 Infection and Vaccination Coverage among Fragile Populations in a Local Health Area of Northern Italy.

Italy was dramatically hit by the COVID-19 pandemic, and the province of Brescia was one of the epicenters of the outbreak. Furthermore, Brescia has one of the highest incidences of people living with HIV (PLWH) and a substantial presence of migrants. We conducted a retrospective cohort study involving all citizens connected to the Brescia Health Protection Agency, assessing the SARS-CoV-2 burden, COVID-19 prevalence, and vaccination coverage.

Tuberculosis trend among native and foreign-born people over a 17 year period (2004-2020) in a large province in Northern Italy.

Tuberculosis (TB) incidence should decline by 20% in the Europe in 2015-2020, in line with End-TB milestones. We retrospectively evaluated TB notifications in the province of Brescia from 2004 to 2020. Cases were classified per patient origin and entitlement to Health Assistance for foreign born people: Italians (ITA), Foreigners permanently entitled (PEF) or Temporarily Entitled (TEF) to Health Regional Assistance.

Polychlorinated biphenyls and risk of hepatocellular carcinoma in the population living in a highly polluted area in Italy.

Polychlorinated biphenyls (PCBs) are human carcinogens, based on sufficient evidence for melanoma and limited evidence for non-Hodgkin lymphoma and breast cancer. Few data are available for liver cancer, although PCBs cause it in rats and determined liver damage in poisoned people. We investigated the association between PCB serum levels and hepatocellular carcinoma (HCC) with a case-control study in a PCB-polluted area in North Italy.

Magnitude and time-course of excess mortality during COVID-19 outbreak: population-based empirical evidence from highly impacted provinces in northern Italy.

Background: The real impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on overall mortality remains uncertain as surveillance reports have attributed a limited number of deaths to novel coronavirus disease 2019 (COVID-19) during the outbreak. The aim of this study was to assess the excess mortality during the COVID-19 outbreak in highly impacted areas of northern Italy.

Methods: We analysed data on deaths that occurred in the first 4 months of 2020 provided by the health protection agencies (HPAs) of Bergamo and Brescia (Lombardy), building a time-series of daily number of deaths and predicting the daily standardised mortality ratio (SMR) and cumulative number of excess deaths through a Poisson generalised additive model of the observed counts in 2020, using 2019 data as a reference.

The Wide Spectrum of COVID-19 Clinical Presentation in Children.

Ten months after its appearance in December 2019, SARS-CoV-2 has infected more than 25 million patients worldwide. Because children were first identified as potential spreaders of the virus, schools were closed in several countries. However, it rapidly became evident that the number of hospitalized children infected by SARS-CoV-2 was dramatically lower than that of adults.

Childhood Langerhans cell histiocytosis with severe lung involvement: a nationwide cohort study.

Background: Lung involvement in childhood Langerhans cell histiocytosis (LCH) is infrequent and rarely life threatening, but occasionally, severe presentations are observed.

Methods: Among 1482 children (< 15 years) registered in the French LCH registry (1994-2018), 111 (7.4%) had lung involvement.

Severe central apnea secondary to cerebellar dysplasia in a child: look past Joubert syndrome.

We report the case of a female patient aged 12 years referred to our pediatric sleep unit with a history of central sleep apnea associated with transient episodes of tachypnea on polysomnography recordings. The patient was otherwise healthy, with no personal or family medical history, and had a normal physical and neuropsychological examination. Brain magnetic resonance imaging showed signs of cerebellar vermis dysplasia but without the classical features of the molar tooth sign.

Polychlorinated biphenyls (PCBs) and risk of dementia and Parkinson disease: A population-based cohort study in a North Italian highly polluted area.

Background: Serum polychlorinated biphenyls (PCBs) have been associated with some chronic diseases, but little evidence exists on their possible relationship with neurodegenerative diseases. We aimed to assess the relationship between PCB exposure and the occurrence of dementia and Parkinson disease in a prospective cohort study in a highly polluted area (Brescia-Caffaro).

Methods: PCB exposure was assessed by measuring serum levels of 24 congeners.

Interstitial lung diseases in children.

Interstitial lung disease (ILD) in children (chILD) is a heterogeneous group of rare respiratory disorders that are mostly chronic and associated with high morbidity and mortality. The pathogenesis of the various chILD is complex and the diseases share common features of inflammatory and fibrotic changes of the lung parenchyma that impair gas exchanges. The etiologies of chILD are numerous.

Cardiac MRI in Children with Multisystem Inflammatory Syndrome Associated with COVID-19.

This case series examines cardiac MRI findings in four children and adolescents admitted to intensive care in April 2020 for multisystem inflammatory syndrome and Kawasaki disease-like features related to coronavirus disease 2019 (COVID-19). Acute myocarditis occurred less than 1 week after onset of fever and gastrointestinal symptoms. Physical examination showed rash and cheilitis or conjunctivitis.

Polychlorinated biphenyls (PCBs) and risk of hypertension: A population-based cohort study in a North Italian highly polluted area.

This study aimed to assess the longitudinal association between PCB exposure and the subsequent occurrence of hypertension in a highly polluted area. The study subjects had at least one PCB serum measurement between 2003 and 2014 and were followed up to the end of 2017. Hypertension cases were obtained from the Brescia Health Protection Agency database.

Use of ruxolitinib in COPA syndrome manifesting as life-threatening alveolar haemorrhage.

COPA (coatomer subunit α) syndrome is a newly recognised cause of interstitial lung disease in children and adults, frequently associated with arthritis and renal dysfunction. We report a 11-year-old girl with disease limited to major pulmonary haemosiderosis manifesting at the age of 2 years, due to a heterozygous p.(Arg233His) mutation in Her interferon (IFN) signature was elevated (10.

Pulmonary Fibrosis in Children.

Pulmonary fibrosis (PF) is a very rare condition in children, which may be observed in specific forms of interstitial lung disease. None of the clinical, radiological, or histological descriptions used for PF diagnosis in adult patients, especially in situations of idiopathic PF, can apply to pediatric situations. This observation supports the view that PF expression may differ with age and, most likely, may cover distinct entities.

Childhood pulmonary Langerhans cell histiocytosis: a comprehensive clinical-histopathological and BRAF mutation study from the French national cohort.

Childhood pulmonary Langerhans cell histiocytosis (PLCH) is a rare disease. Its pulmonary histopathology, according to comprehensive clinical-radiological findings and BRAF mutation status, has not yet been thoroughly documented. From the 167 childhood PLCH cases entered in the French National Histiocytosis Registry (1983-2016), we retrieved lung biopsies from a consecutive retrospective series of 17 patients, diagnosed when they were 2 weeks to 16 years old (median, 9.
