Review
Neuroendocrine tumors (NETs) can have multiple localizations in the human body however, most often, it appears in the in thorax at tracheobronchial tree and the thymus. NETs are a group of tumors with heterogenous malignancy that evolve from neuroendocrine cells, with the lung being the second target organ after the gastrointestinal tract. These rare tumors are usually asymptomatic and non-functional with little information regarding incidence in the specialty literature. The main purpose of this review, was the analysis of the available literature in all aspects while mainly focusing on molecular diagnosis data and secondly, by using this molecular landscape to establish a differentiation of lung neuroendocrine tumors (LNETs). By analyzing the literature, new data were revealed regarding histological evaluation, genetic aberrations, prognosis depending on the type of LNET and therapeutic options that derive from these. Efficient management of these tumors is essential in the handling of symptoms and increase in life expectancy, especially in patients with functional tumors. Histological differentiation of LNETs is important in establishing proper therapeutic options and prognosis. Combined types of LNETs remain a controversial topic of discussion regarding diagnosis and treatment, a topic on which further studies are required in order to improve diagnosis in this group of tumors with heterogenous malignancy.

Review
The aim of this study was to investigate the features of partial anomalous left pulmonary artery (PALPA) and differences between cases with posterior versus anterior a nomalous vessels in relation to the tracheobronchial tree. We hypothesized that statistical significance was dependent on the course of the anomalous vessel due to airway compression in the posterior type. This study included cases obtained from the literature ( = 33) and an institution teaching file ( = 2). Information collected: age, sex, medical history, additional anomalies, anomalous vessel course, and respiratory symptoms. Data were analyzed with independent samples -test and Fisher's exact test. PALPAs were more commonly anterior than posterior. Mean age: 5.3 years (SD = 12.4) for anterior and 6.8 years (SD = 18.5) for posterior ( = 0.77). Respiratory symptoms: 20% of anterior and 60% of posterior cases ( = 0.032). Tracheobronchial anomalies: 35% of anterior and 60% of posterior cases ( = 0.182). Non-cardiac and non-tracheobronchial anomalies: 30% of anterior and 47% of posterior cases ( = 0.511). Kabuki syndrome: 25% of anterior and 6.7% of posterior cases ( = 0.207). In conclusion, respiratory symptoms were the only significant difference between anterior and posterior PALPA types.

Meta-Analysis Review
OBJECTIVE
To clarify issues regarding the frequency, prevention, outcome, and treatment of patients with ventilator-associated tracheobronchitis (VAT), which is a lower respiratory tract infection involving the tracheobronchial tree, while sparing the lung parenchyma.
METHODS
We performed a systematic review and meta-analysis of relevant available data, gathered though searches of PubMed, Scopus, and reference lists, without time restrictions. A conservative random effects model was used to calculate pooled odds ratios (OR) and 95% confidence intervals (CI).
RESULTS
Out of the 564 initially retrieved articles, 17 papers were included. Frequency of VAT was 11.5%. Selective digestive decontamination was not proved an effective preventive strategy against VAT (OR: 0.62, 95% CI: 0.31e1.26). Presence, as opposed to the absence, of VAT was not associated with higher attributable mortality (OR: 1.02, 95% CI: 0.57e1.81). Administration of systemic antimicrobials (with or without inhaled ones), as opposed to placebo or no treatment, in patients with VAT was not associated with lower mortality (OR: 0.56, 95% CI: 0.27e1.14). Most of the studies providing relevant data noted that administration of antimicrobial agents, as opposed to placebo or no treatment, in patients with VAT was associated with lower frequency of subsequent pneumonia and more ventilator-free days, but without shorter length of intensive care unit stay or shorter duration of mechanical ventilation.
CONCLUSIONS
Approximately one tenth of mechanically ventilated patients suffer from VAT. Antimicrobial treatment of patients with VAT may protect against the development of subsequent ventilator-associated pneumonia and improve weaning outcome.

Inflammatory myofibroblastic tumour (IMT) is a rare tumour affecting the tracheo-bronchial tree in the adult population. The clinical presentation of this tumour is diverse and diagnosis can be definitively clinched by histopathological examination. Treatment of this tumour usually requires surgical resection with bronchoscopic resection being described in few cases. We describe a 32 year old male presenting with hemoptysis who was diagnosed to have IMT. Resection of the tumour was done with the help of rigid bronchoscopy. Post-resection, hemoptysis stopped and no recurrence of tumour was noted on subsequent follow-up. We also present a systematic review of literature of all the cases of tracheo-bronchial IMT treated with bronchoscopic resection and conclude it to be a useful alternative to surgery in such cases.
