Inventory of landslides triggered by an extreme rainfall event in Marche-Umbria, Italy, on 15 September 2022.

Systematic and timely documentation of triggered (i.e. event) landslides is fundamental to build extensive datasets worldwide that may help define and/or validate trends in response to climate change. More in general, preparation of landslide inventories is a crucial activity since it provides the basic data for any subsequent analysis. In this work we present an event landslide inventory map (E-LIM) that was prepared through a systematic reconnaissance field survey in about 1 month after an extreme rainfall event hit an area of about 5000 km2 in the Marche-Umbria regions (central Italy). The inventory reports evidence of 1687 triggered landslides in an area of ~550 km2. All slope failures were classified according to type of movement and involved material, and documented with field pictures, wherever possible. The database of the inventory described in this paper as well as the collection of selected field pictures associated with each feature is publicly available at figshare.

Osler-Rendu-Weber syndrome: congenital arteriovenous intrapulmonary fistula treated using a percutaneous Amplatzer plug.

Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations (PAVMs) of the lung that could lead to severe hypoxiemia due to right-to-left intrapulmonary shunts. They may occur as isolated entities or associated with Osler-Rendu-Weber syndrome or hereditary haemorrhagic telangiectasia (HHT). We report a case of a 70 years old woman with Rendu-Osler-Weber disease and a large arteriovenous malformation involving the left pulmonary artery. We describe the successful transcatheter occlusion of the PAVF using an Amplatzer vascular plug. This work is an attempt to focus the attention on pulmonary arteriovenous malformations and on percutaneous treatment as an alternative to surgery, that consists of a conservative lung resection.

Sarcoidosis of the breast: a rare case report and a review.

Sarcoidosis is an idiopathic systemic inflammatory granulomatous disorder comprised of epithelioid and multinucleated giant cells with little necrosis. It usually invades the lungs with fibrosis and may also involve lymph nodes, skin, liver, spleen, eyes, phalangeal bones, and parotid glands. Breast involvement is extremely rare, but, when present, it could be confused with a benign or, more important, a malignant neoplasm. We have reported a case of sarcoidosis of the breast in a 51 years old woman with systemic manifestations of sarcoidosis (arthralgias and uveitis) associated with a breast mass and with a clinical history of fibrocystic mastopathy. A chest X-ray and a Computed Tomography (CT), with raised serum levels of Angiotensin Converting Enzyme (ACE), were compatible with a diagnosis of sarcoidosis. The mammography and ultrasonogram showed a solitary little nodular lesion localized in the breast. A breast cancer in a patient with sarcoidosis? To answer this question, the patient performed breast surgery under general anaesthesia and bioptic microscopic examination showed a typical sarcoid granuloma.

Carcinoembryonic antigen, tissue polypeptide antigen and neuron-specific enolase pleural levels used to classify small-cell and non-small-cell lung cancer patients by discriminant analysis.

The classification of lung cancer into small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC) is essential for disease prognosis and treatment. For this purpose, we have tried to optimize the use of three tumour markers determined on pleural effusions, to differentiate SCLC from NSCLC by means of a canonic variable, generated by discriminant analysis, including subjects with histologically proven lung cancer. Discriminant analysis was performed by using carcinoembryonic antigen, neuron-specific enolase and tissue polypeptide antigen pleural levels, determined in 65 consecutive and unselected patients, histologically classified as 49 NSCLC and 16 SCLC. To validate the formula generated, a control group of 37 lung cancer patients (10 SCLC and 27 NSCLC), enrolled subsequently, was employed. Applying the discriminant analysis to SCLC and NSCLC patients a good classification was obtained (92% rate of correct classification). The aforementioned formula, applied to the validation group, showed a 92% rate of correct classification. This method, which is rapid, inexpensive and routinely applicable to malignant pleural effusions, may be reliably used to classify lung cancer patients.

Solitary plasmacytoma of the chest wall. A case report.

Solitary plasmacytic lymphomas are rarely described in the lung. Generally, localized neoplasms develop into mediastinal or pulmonary lymphnodes and are hard to differentiate from other lung neoplasms. An involvement of the chest wall in multiple myeloma is not rare, and is generally associated with other skeletal localizations. A secreting solitary plasmacytoma of the ribs is rather uncommon: a personal review of the literature has showed, in the last ten years, only two cases of these tumors, secreting IgG lambda light chains. In this study we report a case of solitary plasmacytoma of the chest wall, associated with an IgG kappa monoclonal gammapathy.

Combined treatment in advanced stages (IIIb-IV) of non-small cell lung cancer.

Chemotherapy regimens based on platinum represent the reference standards in Non-Small Cell Lung Cancer (NSCLC) and when it is associated with radiotherapy and/or surgery (combined treatment) it improves survival of patients. Aim of this study was to estimate the efficacy of chemotherapy, based on high-dose epirubicin plus cisplatin, associated with surgery and/or radiotherapy. Twenty-four inoperable NSCLC patients (15 pts in stage IIIb and 9 in stage IV) were treated with epirubicin (120 mg/m2) plus cisplatin (60 mg/m2), every three weeks for at least 3 cycles up to a maximum of 6. A total of 109 treatment cycles (epirubicin plus cisplatin) were administered and two of 24 patients achieved full response (CR), 9 showed partial response (PR), for an overall response rate of 45.8%, 8 patients (33.4%) achieved stable disease (SD) and 5 (20.8%) progressive disease (PD). Leukopenia aroses in 81.9% of the cycles, anaemia in 36.6% and thrombocytopenia in 14%. After chemotherapy, nausea/vomiting was present in 33.3% of patients, while in a small number of cases there were also mucositis, diarrhea, fever, phlebitis, transaminase increase and electrocardiographic anomalies. Upon entry, at the end of therapy patients underwent restaging (CT, bronchoscopy, bone scintiscan) to evaluate the possibility of surgical resection; 15 out of 24 patients completed treatment with radiotherapy (40-60 Gy) and then were re-evaluated for surgery. Five patients underwent complete surgical resection of the neoplasia (4 after chemotherapy and one after radiotherapy). After 1 year survival was 66.6% for all patients. Combined treatment in advanced NSCLC showed a good response and survival after 1 year.

[Pulmonary involvement in sclerodermia]. / Interessamento polmonare in corso di sclerodermia.

Progressive systemic sclerosis (PSS) is a connective tissue disease characterized by fibrosis and thickness of cutis and subcutis (scleroderma) and deterioration of small arteries and capillary vessels, with changeable visceral renal, cardiac, intestinal and pulmonary involvements. The disease is characterized by cutaneous sclerosis, that is to say by the increase of consistence and thickness of cutis that lose her usual elasticity. The sclerosis can be limited to the fingers (sclerodactyly) or can involve otherwise (acrosclerosis); many other time is diffuse also to upper limbs and to thorax (diffuse scleroderma). The disease is rare and its incidence is variable from 2 to 10 x 10(6); more frequently hits women than men in the ratio of 3 to 1 or 8 to 1 (according to certain Authors). In the elderly is more frequently represented by the CREST syndrome (calcinosis, Raynaud's phenomenon, oesophageal dismotility, sclerodactyly, teleangiectasia). The authors have considered nine patients with pulmonary involvement of progressive systemic sclerosis: five with CREST syndrome and four with diffuse scleroderma. In addition to the common routine examinations, we performed chest radiography (CXR), pulmonary function tests, fiberoptic bronchoscopy and bronchoalveolar lavage (BAL), Gallium 67 scanning and high resolution computed tomography (HRCT) with the purpose to consider the role of these medical examinations in diagnosis and the follow-up of pulmonary involvement in scleroderma. From the results we have observed that: 1) in early disease chest radiography may be silent even if the patient shows a restrictive syndrome and reduction of diffusion capacity of carbon monoxide (DLCO); 2) chest radiography, pulmonary function tests and Gallium 67 scanning have traditionally been used to measure the degree of lung involvement in SSP but unfortunately, none of these reliably predicts disease activity or future course; 3) bronchoalveolar lavage shows the degree of lung inflammation (alveolitis) characterized by the increase of total BAL cell counts and by higher neutrophil cells in the initial stage of the disease; 4) even HRCT shows in this stage, the typical aspect of higher endoalveolar cellularity with ground glass appearance. With the progression of anatomical damage, there can be found even appearance of complete destruction of pulmonary architecture with the typical alteration of honeycomb. These findings support the hypothesis that a ground glass appearance on HRCT is the radiographic equivalent of alveolitis found in BAL. Furthermore HRCT shows itself useful in the follow-up the disease and in detecting of its activity condition.(ABSTRACT TRUNCATED AT 400 WORDS)

Primary pulmonary hypertension in a HIV+ patient.

Recent reports have suggested a possible association between HIV infection and primary pulmonary hypertension (PPH). We report the case of a HIV+ patient, without manifestations of the acquired immune deficiency syndrome (AIDS), who presented with signs of elevated pulmonary arterial pressure.

[Idiopathic pulmonary hemosiderosis. Clinical and radiological assessment of re-exacerbation]. / Emosiderosi polmonare idiopatica. Valutazione clinica e radiologica della riacutizzazione.

Predominant characteristics of idiopathic pulmonary hemosiderosis (IPH), a rare pathology of unknown etiology, are recurrent alveolar hemorrhage, hemoptysis and iron deficiency anemia. No evidence of vascular disorders, infections, cancer, pulmonary embolus, veno-occlusive diseases must also be considered for the diagnosis. A case of chronic IPH with long asymptomatic periods and stages of riacutization with severe dyspnoea, high fever, cough with rusty coloured spitting, asthenia and serious respiratory insufficiency is described. The patient adds to our understanding in one of such riacutization in that she agreed to high-resolution computed tomography (HRCT) testing, in addition to common routine testing. It became possible to underline the importance of HRCT both in the diagnosis of IPH without hemoptysis, awaiting invasive investigations like fiberoptic bronchoscopy and lung biopsy, and in the clinical evaluation of the riacutization. Such analysis leads to forwarding the installment of the most appropriate therapy and to the limitation of fibrotic evolution, when possible.

Mycobacterial antigen complex A60-specific T-cell repertoire during the course of pulmonary tuberculosis.

The Mycobacterium bovis antigen complex A60 is known to be immunodominant in tuberculosis and to have a protective effect against experimental infection in vitro and in vivo. To identify immunodominant and possibly protective antigens in pulmonary tuberculosis, the T-cell repertoire directed to nitrocellulose-bound fractions of A60 antigen was analyzed in active tuberculosis patients during the course of the infection and after recovery. The results show that patients infected with Mycobacterium tuberculosis acquired complete A60-T-cell reactivity only in the late phases of infection. At disease onset, patients with active tuberculosis were characterized by (i) T-cell unresponsiveness to most A60 fractions, (ii) high tumor necrosis factor alpha production, and (iii) low gamma interferon (IFN-gamma) release. Several weeks after chemotherapy, the unresponsive state disappeared and the following reverse situation was observed: (i) high blastogenic response to almost all A60 fractions, (ii) low tumor necrosis factor alpha release, and (iii) high IFN-gamma production. In addition, 60% of these patients significantly responded against seven A60 fractions (61 to 58, 56 to 53, 49 to 46, 46 to 44, 35 to 33, 33 to 30, and 30 to 28 kDa), indicating that they included immunodominant antigens. Furthermore, only the fractions within the molecular mass ranges of 56 to 44 and 35 to 28 kDa induced IFN-gamma synthesis. One year after complete recovery from infection, more than 60% of past-active tuberculosis subjects had memory T cells specific for the immunodominant fractions of 61 to 58, 56 to 53, 49 to 46, and 33 to 30 kDa. Since the same fractions induced the strongest IFN-gamma production, known to exhibit antimycobacterial effects, it is suggested that these may represent the inducers of a protective immune response.
