The lung cancer mortality is frequently associated with late diagnosis, therefore an early diagnosis is a key factor to significantly improve overall survival in high risk populations of asymptomatic patients. Conventional cancer screenings (low-dose computed tomography or chest x-ray) today offers early detection but are invasive and expensive. Up to date these studies evaluated the solid and topographic cancer structure and morphology. Today the concept of tumor has been remodeled and it has been defined as a disease that has its own genetic, biological and metabolic identity and on this new awareness we should base the new screening methods. Recent research has shown great reliability of new tests as exhaled breath analysis, serum biomarkers and urine analysis in early diagnosis of lung cancer. The analysis of new biomarkers associated with a high specificity of this new screening methods, that are non-invasive, safety, inex...

Data from all adults with uncomplicated appendicitis treated by laparoscopic appendectomy between June 2012 and December 2015 were prospectively collected. Patients with chronic pain, appendix malignancy, at least two previous laparotomies, and those undergoing concomitant surgery for different condition were excluded from analysis. Postoperative pain was assessed by a visual analog scale (VAS). Patients were reviewed postoperatively at 7 days and 1 month in the outpatient clinic. Late complications were assessed with a telephonic interview. A total of 91 patients were included (46 SILA; 45 3-PORT). There were 16 males and 30 females in the SILA group (mean age = 26.76 ± 10.58 years) and 18 males and 27 females in the 3-PORT group (mean age = 26.84 ± 10.79 years). The mean operative time for SILA was 48.54 ± 12.80 min, for the 3-PORT group the mean operative time was 46.33 ± 15.54 min (P = 0.46). No case required conversion. Mean postoperative hospital length of stay was 1.87 ± 0.69 days for SILA and 2.38 ± 1.11 days for 3-PORT (P = 0.01). VAS value of 3.91 ± 1.96 and mean ketorolac usage of 0.38 ± 0.65 in 3-PORT group and SILA patients reported 3.70 ± 1.58 and 0.39 ± 0.58, respectively (P = 0.91). Our mean follow-up in SILA group was 25.75 ± 10.82 months, for 3-PORT group the mean follow-up was 26.9 ± 11.8 months. Eleven patients missed long-term follow-up. No incisional hernia was found. There is a statistically significant difference in cosmetic evaluation in favor of SILA (P < 0.005). There was no difference in operative time, early complications, postoperative pain, analgesia requirement between SILA and 3-PORT laparoscopic appendectomy, but after SILA procedure discharge was quicker and long-term cosmetic satisfaction was superior.

This case-control study was designed to test the sealing efficacy and safety of Enable-Innoseal TP4 in patients undergoing pulmonary resection for lung cancer. This was a case-control trial enrolling patients with primary or single site metastatic lung cancer scheduled for elective anatomic or nonanatomic pulmonary resection presenting intraoperative grade 1 or 2 air leak at water submersion test; the study group population was then matched 1:1 according to surgical procedure, male/female ratio, preoperative FEV1, and age. In the study population, 21 patients (70.0%) presented intraoperative grade 1 air leak and 9 patients grade 2 (30.0%) air leak; after comparison with the control group, we observed a significant shorter time for chest drain removal in the study population (P = 0.0050), whereas no difference was registered in terms of number of days needing for discharge (P = 0.0762). Enable-Innoseal TP4 was effective in treating limited intraoperative air leaks after pulmonary resection and preventing prolonged postoperative air leaks in patients receiving either anatomic or nonanatomic lung resections. Further randomized double-arm studies are required to confirm the efficacy of Enable-Innoseal TP4 demonstrated by this pilot study.

Several independent researchers point out that the breath of lung cancer patients shows a characteristic VOC-profile which can be considered as lung cancer signature and, thus, used for diagnosis. In this regard, the analysis of exhaled breath with gas sensor arrays is a potential non-invasive, relatively low-cost and easy technique for the early detection of lung cancer. This clinical study evaluated the gas sensor array response for the identification of the exhaled breath of lung cancer patients. This study involved 146 individuals: 70 with lung cancer confirmed by computerized tomography (CT) or positron emission tomography-(PET) imaging techniques and histology (biopsy) or with clinical suspect of lung cancer and 76 healthy controls. Their exhaled breath was measured with a gas sensor array composed of a matrix of eight quartz microbalances (QMBs), each functionalized with a different metalloporphyrin. The i...

In patients with failed multimodal treatment, or in those who develop an isolated recurrence, surgical resection may be useful to remove all macroscopically evident diseases. However, the procedure may be technically demanding and there are no published data regarding its benefits. The aim of the present study was to evaluate the feasibility and safety of subclavicular resection in breast cancer and provide indications as to whether it can contribute to disease control. We used a transpectoral approach to surgically remove isolated breast cancer recurrence in the subclavicular region in seven consecutive patients presenting over 2 years; in the eighth case a transmanubrial approach was necessary. We found that the surgical approach proposed is feasible and safe, with a 75% rate of complete resection; however, the series was characterised by a high rate of local and distant relapse. We conclude that the technique may be useful, in selected cases, for palliation only.

In this work, we investigate some structural properties of CMEs and their solutions, with a particular focus on the efficient computation of the stationary distribution. We introduce a generalized notion of one-step process, which results in a sparse dynamical matrix describing the collection of the scalar CMEs, also showing a recursive block-tridiagonal structure.

We assessed our experience with partial or circumferential resection of the PA during lung resection. Between 1998 and 2013, we performed PA angioplasty in 150 patients with lung cancer. Partial PA resection was performed in 146 patients. PA reconstruction was performed by running suture in 113 patients and by using a pericardial patch in 33. A circumferential PA resection was performed in 4 patients, and reconstruction was made with polytetrafluoroethylene and by a custom-made bovine pericardial conduit. Bronchial sleeve resection was associated in 56 patients. Stage I disease was present in 32 patients, stage II in 43, stage IIIA in 51, and stage IIIB in 17. Seventy-five patients received induction chemotherapy, and 7 patients had a complete response. Thirty-day mortality was 3.3% (n = 5); two of these patients died of a massive hemoptysis. Pulmonary complications occurre...

One hundred forty-five patients who underwent pulmonary lobectomy for lung cancer and with an air leak on the first postoperative day were prospectively randomly assigned to two groups: in group 1 (72 patients), chest tubes were placed on water seal on the morning of the first postoperative day; in group 2 (73 patients), chest tubes were on continuous suction (-20 cm H(2)O). Eighty percent of the patients who underwent upper lobectomy had also a pleural tent procedure. Preoperative, operative, and postoperative variables were compared between the groups. The two groups were evenly matched for preoperative and operative characteristics. No statistically significant differences were found between group 1 and group 2 in terms of air leak duration (6.5 versus 6.3, respectively; p = 0.9) and the incidence of prolonged...

Mesenchymal stromal cells (MSCs) are a population of undifferentiated multipotent adult cells that naturally reside within the human body, which can differentiate into osteogenic, chondrogenic, and adipogenic lineages when cultured in specific inducing media. MSCs have the ability to migrate and engraft at sites of inflammation and injury in response to cytokines, chemokines, and growth factors at a wound site and they can exert local reparative effects through transdifferentiation and differentiation into specific cell types or via the paracrine secretion of soluble factors with anti-inflammatory and wound-healing activities. Experimental and clinical evidence exists regarding MSCs efficacy in airway defects restoration; although clinical MSCs use, in the daily practice, is not yet completely reached for airway diseases, we can argue that MSCs do not represent any more merely an experimental approach to airway tissue defects restoration but they can be considered as a "salvage" therapeutic tool in very selected patients and diseases.

An immediate BPF occurring intraoperatively after bronchial closure is a rare event and is usually treated by bronchial stump reamputation and/or hand-suture reinforcement by mattress suture, or myoplasty. We report a simple and successful technique, using azygous vein flaps, to repair an intraoperative BPF associated to a small bronchial dehiscence occurred after a right pneumonectomy in a 70-year-old diabetic man receiving induction chemotherapy treatment.

Solitary fibrous tumor of the kidney is extremely rare with fewer than 15 reported cases in modern English literature. To the best of our knowledge, this report describes the first known case of synchronous SFTP in the left parietal pleura and left kidney. The SFTP of the pleura, widely compressing and displacing the left lower lung lobe, was resected via left thoracotomy, whereas the renal SFTP, diagnosed by echo-guided histological biopsy, was closely monitored by computed tomography scan and ultrasound. After a one-year follow-up no recurrence was detected in the left hemithorax and the renal lesion remained stable.

One hundred and ninety patients submitted to pulmonary lobectomy or pneumonectomy for lung cancer performed preoperative and early postoperative (mean 10.9 after operation) pulmonary function tests. One hundred and fifty of these patients also underwent DLCO measurements by the single breath method. The decline of FEV1 and DLCO were expressed as percentage losses from preoperative values. Stepwise multiple regression analyses were performed to develop two models estimating the percent reduction of FEV1 and DLCO from preoperative values. The multivariate procedures were then validated by bootstrap analyses. The following regression equations were derived: estimated percent reduction in FEV1 = 21.34 - (0.47 x age) + (0.49 x percentage of functioning par...
