Abstract
Multiple myeloma is a malignant neoplasm of plasma cells that usually invades the bone marrow replacing normal bone marrow and producing large amounts of light chains of immunoglobulins (Ig) [1]. Clinical manifestations are related to the accumulation of these proteins in vital organs such as kidney and heart. Pleural effusion may be a sign of chest involvement that occurs in approximately 6% of patients with Known multiple myeloma [2,3]. We present the case of an 80-year- old man with pleural effusion as first extra-medullary clinical presentation of an occult multiple myeloma.

Abstract
BACKGROUND Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal-dominant inherited disorder characterized by inactivation of the gene Folliculin (FLCN), pulmonary cysts with recurrent spontaneous pneumothorax, dermatological lesions, and an increased risk of developing renal malignancies. OBJECTIVES We aimed to investigate the real prevalence of BHDS and its prevalence among patients with a familial history of pneumothorax. METHODS From July 2014 to December 2016, we consecutively studied all patients with spontaneous pneumothorax and a positive family history for the same condition referring to our Institution. The suspicious cases underwent genetic analysis of the BHDS-causative gene FLCN. FLCN-positive cases were further evaluated with routine blood tests, chest radiography, chest CT, abdominal MRI, and dermatological evaluation. RESULTS Among 114 patients admitted with spontaneous pneumothorax, 7 patients had a family history of pneumothorax, and 6/7 (85.7%) patients had positive genetic test for FLCN as well as 7/13 family members. Pulmonary cysts were found in all patients with a FLCN-positive genetic test. Most patients (10/13, 76.9%) had tiny pulmonary cysts less than 1 cm in diameter. The vast majority of cysts were intraparenchymal (12/13, 92.3%) and located in lower lobes. Dermatological lesions were found in 7/13 (54%) patients, renal cysts in 4/13 (31%) patients, and renal cancer in 1 (1/13, 7.7%) patient. CONCLUSIONS Although BHDS is considered a rare disease, BHDS underlies spontaneous pneumothorax more often than usually believed, especially whenever a family history of pneumothorax is present. Diagnosis of BHDS is essential to start monitoring patients for the risk of developing renal malignancies.

Abstract
Idiopathic pulmonary fibrosis is a peripheral subpleural interstitial lung disorder limited to the lung not involving the airways. It has a poor prognosis (survival less than 5 years) and commonly an interstitial pneumonia radiological pattern. Patients complain of a chronic dry cough in 80% of cases. A cough is often the first symptom of this rare disease, preceding dyspnea by years, and is associated with a poor prognosis, high dyspnea scores and low FVC percentages. The pathogenetic mechanisms leading to coughing in IPF are unclear. This review focuses on recent evidence of cough pathophysiology in this disease. Gastroesophageal reflux may promote coughing in IPF patients; bile salts and pepsin may be abundant in BAL of these patients, inducing overproduction of TGF-β by airway epithelial cells and mesenchymal transition with fibroblast recruitment/activation and extracellular matrix deposition. Patients have an enhanced cough reflex to capsaicin and substance P with respect to control subjects. Moreover, patients with the MUC5B polymorphism show more severe coughing as MUC5B encodes for the dominant mucin in the honeycomb cysts of IPF patients. Comorbidities, including asthma, gastroesophageal reflux, hypersensitivity pneumonitis, bronchiectasis, chronic obstructive pulmonary disease and emphysema, can induce coughing in IPF patients. There is no clear explanation of the causes of coughing in IPF. Further research into the pathophysiology of IPF and the pathogenetic mechanisms of coughing is necessary to improve survival and quality of life.

Abstract
Background To evaluate the efficacy of Endo-Bronchial Valves in the management of persistent air-leaks (PALs) and the procedural cost. Methods It was a retrospective multicenter study including consecutive patients with PALs for alveolar pleural fistula (APF) undergoing valve treatment. We assessed the efficacy and the cost of the procedure. Results Seventy-four patients with persistent air leaks due to various etiologies were included in the analysis. In all cases the air leaks were severe and refractory to standard treatments. Sixty-seven (91%) patients underwent valve treatment obtaining a complete resolution of air-leaks in 59 (88%) patients; a reduction of air-leaks in 6 (9%); and no benefits in 2 (3%). The comparison of data before and after valve treatment showed a significant reduction of air-leak duration (16.2±8.8 versus 5.0±1.7 days; P<0.0001); chest tube removal (16.2±8.8 versus 7.3±2.7 days; P<0.0001); and length of hospital stay (LOS) (16.2±8.8 versus 9.7±2.8 days; P=0.004). Seven patients not undergoing valve treatment underwent pneumo-peritoneum with pleurodesis (n=6) or only pleurodesis (n=1). In only 1 (14%) patient, the chest drainage was removed 23 days later while the remaining 6 (86%) were discharged with a domiciliary chest drainage removed after 157±41 days. No significant difference was found in health cost before and after endobronchial valve (EBV) implant (P=0.3). Conclusions Valve treatment for persistent air leaks is an effective procedure. The reduction of hospitalization costs related to early resolution of air-leaks could overcome the procedural cost.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis has a median survival time after diagnosis of 2-5 years. The main goal of treating IPF is to stabilize or reduce the rate of disease progression. Nintedanib and Pirfenidone have been a breakthrough in the management of IPF. Here we evaluated the effectiveness of Pirfenidone and Nintedanib in a population of IPF patients diagnosed in the last 12 months at Florence ILD Referral Centre. METHODS In the last 12 months, 82 IPF patients (66 male, mean age 78.3±23.8 years) were diagnosed and started antifibrotic therapy with Pirfenidone or Nintedanib. Their clinical and functional details were analyzed retrospectively at time 0 and after 6 and 12 months of therapy. RESULTS The median age of the patients treated with Nintedanib was higher than that of the Pirfenidone group (p<0.0001). The most common symptoms at disease onset were exertional dyspnoea and dry cough with no differences between the two groups (p<0.05). All IPF patients manifested bibasal crackles at the time of diagnosis. No significant differences in FVC, FEV1, TLC and DLCO were found at time 0 or after 6 months between patients treated with Pirfenidone and Nintedanib (p>0.05). After 1 year, lung function test parameters of patients treated with Pirfenidone had remained stable from baseline. DISCUSSION This study emphasizes that both antifibrotic drugs appeared to be a good therapeutic choice in terms of functional stabilization, also in older patients.

Abstract
A patient treated for 4 months with hydroxycarbamide (hydroxyurea) for chronic myelomonocytic leukemia was admitted to hospital for recently developed severe dyspnea and acute respiratory failure. The computed tomographic scan of the chest showed diffuse ground glass opacities, some centrilobular low-density nodules (resembling hypersensitivity pneumonitis-like pattern), and minimal interstitial reticulation of the subpleural region. The analysis of bronchoalveolar lavage fluid excluded infection, as did serological examinations. The patient was started on oxygen therapy and with relief of thrombocytopenia and suspected hemolytic anemia, hydroxyurea treatment was discontinued. The patient underwent steroid therapy, with a rapid progressive improvement of clinical and radiological features. As hydroxyurea is increasingly used for a number of systemic disorders, physicians must be aware of its potential lung toxicity, requiring immediate cessation of the treatment and empiric corticosteroid therapy.

Abstract
The involvement of the musculoskeletal system with other mild pleiotropic manifestations represents a clinical criterion, called "systemic features," to d iagnose Marfan's syndrome. We aimed to investigate the features of the hands and feet redressable contractures present in a group of Marfan patients. In 13 patients with previously diagnosed Marfan's syndrome, an accurate clinical examination was performed. In particular the characterization of the musculoskeletal system by visual analogic scale to measure muscle pain (VAS) and muscle strength (MRC system) was carried out; the Beighton scale score was used to evaluate the articular hypermobility. Ultrasound examination (US) was performed to detect deep-superficial flexor tendons and extensor tendons of both hands, and the short and long flexor and extensor tendons of the fingers and toes in static and dynamic positions. The ImageJ program was adopted to measure a profile of tendon echo-intensity. A reduction of the thickness of all tendons was detected by US in our patients; the VAS and Beighton scale scores were in normal ranges. The profile of tendon echo-intensity showed different textural details in all Marfan patients. This study provides evidence for other contractures' localization, and for altered findings of the tendons in patients with Marfan syndrome and finger/toe contractures. These changes may be associated with structural modifications in connective tissue.

Abstract
A wild-type and a Cr-tolerant strain of the unicellular green alga Scenedesmus acutus were used to investigate if the difference in tolerance to Cr(VI) could depend on a different response to oxidative stress in terms of free cysteine (Cys) and reduced glutathione (GSH), and in preventing membrane lipid peroxidation. The growth of the two strains in standard medium in the presence of Cr(VI) 9.6, 19.2 or 38.4microM was compared, and the content of thiobarbituric acid reactive substances (TBARS) after a 4-day treatment was determined as marker of lipid peroxidation. The Cys and GSH contents were determined in both strains treated with Cr(VI) for 24h in HEPES buffer both enriched and not with sulphate. The treated algae were also subjected to recovery test in standard medium. The growth of wild type was inhibited at all Cr(VI) concentrations, while that of the Cr-tolerant strain only at the highest one. After exposure to 19.2microM Cr(VI), TBARS levels ranging from 0.091 to 0.263micromol/g d.w. were detected in the wild type, while only a slight increase (0.090+/-0.014micromol/g d.w.) was observed in the Cr-tolerant strain. Following treatment with 38.4microM Cr(VI), TBARS levels rose significantly and were similar in the two strains. The Cys content did not vary significantly in the cells exposed to Cr(VI) in either sulphate-lacking or sulphate-enriched buffer, and the differences between the two strains were insignificant. In the wild-type strain, the GSH content showed a significant downward trend with the increase in Cr(VI) concentration in the sulphate-lacking buffer, while it remained as high as the one of control cells in the sulphate-enriched buffer. In the Cr-tolerant strain, the GSH content did not vary significantly when the treatment took place in the sulphate-lacking buffer, while it showed a significant rise with the increase in Cr(VI) concentration in the sulphate-enriched buffer. The growth of both strains during recovery was significantly faster after treatment in the sulphate-enriched than in the sulphate-lacking buffer, the Cr-tolerant strain showing a much higher recovery capacity than the wild type. It appears that the Cr-tolerant strain, when exposed to Cr(VI) in the presence of a sulphur source, can increase GSH pool to levels not achievable by the wild type, and is thus able to recover better. This first report on the role of thiol compounds in Cr tolerance in algae suggests that tolerance to Cr(VI) in S. acutus could depend on a prompt up-regulation of the pathways leading to GSH synthesis.

Abstract
Two strains of the unicellular green alga Scenedesmus acutus with different sensitivity to hexavalent chromium were compared for their tolerance of cadmium, by means of growth and recovery tests, and determination of cysteine, reduced glutathione and phytochelatin content, after short-term exposure to various cadmium concentrations (from 1.125 to 27 microM). Growth experiments showed that, after 7-day treatments with cadmium, the chromium-tolerant strain reached a significantly higher cell density and, after 24-h exposure to Cd, was able to resume growth significantly better than the wild type. Constitutive level of cysteine was higher in the chromium-tolerant strain, while glutathione levels were similar in the two strains. The higher content of cysteine and the maintenance of both reduced glutathione and phytochelatin high levels in the presence of cadmium, support the higher cadmium co-tolerance of the chromium-tolerant strain in comparison with the wild type one.
