Clinical impact of COVID-19 on tuberculosis
: During COVID-19 pandemic, a lot of diseases suffered from a limited access to health care services, owing to the use of resources, both technical and financial, mainly directed towards such a dramatic outbreak. Among these, tuberculosis (TB) has been one of the most penalized, with a huge delay both in diagnosis and in start of treatment, with a consequential dramatic increase in morbidity and mortality. COVID-19 and tuberculosis share similar common pathogenetic pathways, and both diseases affect primarily the lungs. About the impact of TB on COVID-19 severity and mortality, data are unclear and literature reports are often conflicting. Certainly, considering the management of coinfected patients, there are pharmacokinetic interactions between several drugs used for the therapy of SARS-CoV-2 infection and the treatment of TB

Sarcoidosis with prevalent and severe joint localization: A case report
BACKGROUND: Sarcoidosis is a systemic granulomatous disease of unknown origin, characterized by the formation of granulomas without central necrosis. Each organ and tissue can be affected by the disease, but in most cases mainly the lungs and mediastinal lymph nodes but also skin, heart, eyes and joints are involved, the latter are mainly the metacarpophalangeal joints and bone lesions are often associated with involvement of the overlying skin. The diagnosis is often of exclusion, based on clinical and radiological suspicion, and should be confirmed by biopsy, although in each case it is necessary to exclude other possible causes of granulomatosis, including infections by mycobacteria. Here it is reported a case of particularly aggressive sarcoidosis with primitive involvement of the small joints of the hands and feet, and mediastinal lymph nodes. CASE PRESENTATION: The subject, a man, 60 years old, born in Morocco but living in Italy for many years, presented important involvement of bone structures and soft periarticular tissue, and was affected by the formation of granulomas without “caseum necrosis”. The painful symptoms and the skin ulceration had led to surgical amputation of the distal phalanges of most fingers of his hands and feet, but with subsequent resurgence of lesions in acral locations after surgery. The PET/CT scan showed an amount of radiotracer in mediastinal lymph nodes, while the lymph nodes sampled by TBNA were normal and the CD4/CD8 ratio was less than 3 in the bronchoalveolar lavage. We ruled out any possible infectious cause, including mycobacterial infection (both tubercular and atypical), so the patient was treated with systemic corticosteroids, with an excellent clinical and radiological response. CONCLUSIONS: Such a case shows how the disease can have variable expressions, without primitive lung involvement; therefore, it should be necessary to consider any possible, unpredictable localization of the disease
Low-dose pulse cyclophosphamide in interstitial lung disease associated with systemic sclerosis (SSc-ILD): efficacy of maintenance immunosuppression in responders and non-responders
To investigate the long-term disease course of patients with recently deteriorated systemic sclerosis (SSC)-interstitial lung disease (ILD) undergoing continuous immunosuppressive treatment with cyclophosphamide (CYC) as induction therapy
Negative and positive implications of social networks in bronchial asthma
Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the
severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of
both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals.
Although social network users often disclose more about themselves online than they do in person, there
might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect
use. However, although some studies show an increased risk of depression, other observations suggest beneficial
effects of social network by enhancing communication, social connection and self-esteem. In addition,
social network represent a useful tool in disseminating public health messages
