Introduction: Staging investigations at diagnosis are customary to accurately assign a clinical stage before therapy. The practice of routine imaging in patients asymptomatic for metastasis is not recommended but widely adopted. This study was done to reexamine the basis behind guideline recommendations and to identify the factors predictive of asymptomatic metastasis. Methods: Oncology records of 200 breast cancer patients in clinical Stages I-III at diagnosis were prospectively reviewed...

Proteoglycans (PGs) are complex, multifaceted molecules that participate in diverse interactions vital for physiological and pathological processes. As structural components, they provide a scaffold for cells and structural organization that helps define tissue architecture. Through interactions with water, PGs enable molecular and cellular movement through tissues. Through selective ionic interactions with growth factors, chemokines, cytokines, and proteases, PGs facilitate the ability of these soluble ligands to regulate intracellular signaling events and to influence the inflammatory response...

Acute pulmonary embolism (APE) is frequently reported in patients with cardiac arrest (CA) in emergency care. Pneumocyte apoptosis is commonly observed in the lungs following an APE. An important pathological mechanism evoking apoptosis during a lipopolysaccharide‑induced acute lung injury is the angiotensin‑converting enzyme 2 (ACE2)/ACE imbalance. The present study uses a porcine model to examine the anti‑apoptotic effects of captopril on APE‑CA and the return of spontaneous circulation (ROSC). Pigs were randomly assigned into four groups: Control, APE‑CA, ROSC‑saline, and ROSC‑captopril...

MicroRNAs play a critical role in chemoresistance and are implicated in various biological and pathological processes of cells. The objective of the present study was to explore the role of miR‑133b and its mechanism in the regulation of cisplatin resistance and tumor progression in cisplatin‑resistant non‑small cell lung cancer (NSCLC) cells. Reverse transcription‑quantitative polymerase chain reaction and western blot assays of the cisplatin‑resistant cell lines A549/DPP and H1299/DDP displayed the reduced expression of miR‑133b and increased expression of glutathione-S-transferase P1 (GSTP1) in the resistant cells compared with the respective parental cell lines A549 and H1299...

Asthma is a pathologically heterogeneous disease, consisting of several phenotypes. Different types of airway inflammation are the cornerstone feature of this condition. Fraction of nitric oxide in exhaled air (FENO) has been proposed as a noninvasive, specific biomarker for eosinophilic airway inflammation and has been shown to be elevated in patients with allergic asthma phenotype. More recent studies indicate that FeNO identifies T-helper cell type 2 (Th2)-mediated airway inflammation with a high predictive value for identifying inhaled corticosteroid (ICS) responsive airway inflammation...

Chronic lung allograft dysfunction continues to be the main contributor to poor long-term allograft survival after lung transplantation. The restrictive phenotype of chronic lung allograft dysfunction carries a particularly poor prognosis. Little is known about the pathogenetic mechanisms involved in restrictive chronic lung allograft dysfunction. In this study, we performed histomorphological and immunohistochemical analysis of restrictive chronic lung allograft dysfunction lungs. Explant lung tissue from 21 restrictive chronic lung allograft dysfunction patients was collected and histopathologic patterns of rejection, fibrosis and vascular changes were scored after routine histochemical stains and additional immunohistochemistry for endothelial markers and C4d...

In lung adenocarcinoma, canonical EML4-ALK inversion results in a fusion protein with a constitutively active ALK kinase domain. Evidence of ALK rearrangement occurs in a minority (2-7%) of lung adenocarcinoma, and only ~60% of these patients will respond to targeted ALK inhibition by drugs such as crizotinib and ceritinib. Clinically, targeted anti-ALK therapy is often initiated based on evidence of an ALK genomic rearrangement detected by fluorescence in situ hybridization (FISH) of interphase cells in formalin-fixed, paraffin-embedded tissue sections...

Histological morphology alone is not sufficient for the pathological diagnosis of malignant mesothelioma. Positive and negative immunohistochemical markers are necessary to differentiate it from lung adenocarcinoma. As calretinin and D2-40, the recognized positive markers of mesothelioma, are expressed in lung adenocarcinoma to some extent, novel markers with high specificity are desirable. In this study, we investigated the applicability of glypican-1 immunohistochemistry to differentiate epithelioid mesothelioma from lung adenocarcinoma...

The involvement of microRNAs in malignant transformation and cancer progression was previously grounded. The observations made by multiple published studies led to the conclusion that some of these small sequences could be eventually used as biomarkers for diagnosis/prognosis. This meta-analysis investigated whether microRNA-181 family members could predict the outcome of patients carrying different types of cancer. We searched the PubMed and Embase databases for studies evaluating the expression levels of miR-181a/b/c/d in patients with cancer, selecting the publications that assessed the relation between low and high levels of one of these four microRNAs and patients' outcome...

Morquio A syndrome (mucopolysaccharidosis IVA, MPS IVA) is a lysosomal storage disease caused by a deficiency of N-acetylgalactosamine-6-sulfate sulfatase, resulting in systemic accumulation of the partially degraded glycosaminoglycans (GAGs), keratan sulfate and chondroitin-6-sulfate. The accumulation of these GAGs leads to distinguishing features as skeletal dysplasia with disproportionate dwarfism, short neck, kyphoscoliosis, pectus carinatum, tracheal obstruction, coxa valga, genu valgum, and joint laxity...

BACKGROUND: Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare type of interstitial pneumonia characterized by fibroelastosis. Patients with IPPFE as well as idiopathic interstitial pneumonia often have autoimmune diseases, which sometimes coincide with hypothyroidism (HypoT). However, there have been no reports on the association between IPPFE and HypoT. The purpose of this study was to evaluate the correlation between IPPFE and HypoT. We also examined the pathological features of the thyroid glands from autopsied cases...

BACKGROUND: The purpose of this study was to clarify the clinico-radio-pathological characteristics and prognostic factors of unclassifiable-idiopathic interstitial pneumonias (U-IIPs) diagnosed by surgical lung biopsy. METHODS: Among 86 patients with interstitial pneumonia who underwent surgical lung biopsy from January 2005 to September 2013, 33 (38.4%; 16 male patients; mean age, 64.4 ± 8.8 years) were diagnosed with U-IIPs. They were subsequently categorized into rapidly progressive (n = 7), slowly progressive (n = 7), and stable (n = 19) groups based on the decrease of the percent predicted forced vital capacity or percent predicted diffusing capacity of the lung carbon monoxide and the occurrence of acute exacerbation...

Sacrococcygeal yolk sac tumor is an uncommon pediatric neoplasm. It usually presents with intra-abdominal or gluteal pain and mass. At later stage, it disseminates to regional nodes and distant organs. We describe one such neoplasm in an 18-month-old male child who turned symptomatic with multiple bilateral lung metastases. The tumor produced the least deformity to his physique, to become detectable on routine inspection and clinical examination. Finally, a combined approach through clinical, radiological, pathological, and biochemical perspectives established the diagnosis...

BACKGROUND: Histopathologists encounter strange structures in tissue sections that appear unrelated to tissues, and these artifacts may be misinterpreted and misdiagnosed as pathological lesions. These substances may either be present within the tissues or can get implanted into tissue during biopsy procedure or laboratory handling or processing. AIMS: The aim of this study is to observe the microscopic appearance of different abnormal structures like commonly implanted food particles or easily incorporated substances during tissue processing with their probable histological misdiagnosis...
