The present study was undertaken to investigate the toxic effects of higher doses (1,00,000 IU i.e. 2.5 mg/kg body weight (BW)) of vitamin D3, concomitantly with bacterial endotoxins (lipopolysaccharides: LPS) to study the immunomodulatory potential of vitamin D3 in IBL-80 broiler chicks. The chicks were divided into four groups [group I (NSS), group II (LPS), group III (Vit. D3 + NSS), and group IV (Vit. D3 + LPS)] containing eight chicks in each group, treated accordingly for 21 days. Birds were kept under close observation for apparent clinical signs and symptoms...

Subsequent to the widespread use of multidetector computed tomography and growing interest in lung cancer screening, small pulmonary nodules are more frequently detected. The differential diagnosis for a solitary pulmonary nodule is extremely broad and includes both benign and malignant causes. Recognition of early lung cancers is vital, since stage at diagnosis is crucial for prognosis. Estimation of the probability of malignancy is a challenging task, but crucial for follow-up and further work-up. In addition to the clinical setting and metabolic assessment, morphological assessment on thin-section computed tomography is essential...

BACKGROUND: Homozygous K108E mutation of interferon regulatory factor 8 (IRF8) is reported to cause dendritic cell and monocyte deficiency. However, more widespread immune dysfunction is predicted from the multiple roles ascribed to IRF8 in immune cell development and function. OBJECTIVE: We sought to describe the effect on hematopoiesis and immunity of compound heterozygous R83C/ R291Q mutation of IRF8, present in a patient with recurrent viral infection, granulo-proliferation and intracerebral calcification...

Video-assisted thoracoscopic surgery (VATS) lobectomy has been employed in recent decades for the treatment of non-small cell lung cancer (NSCLC). Although trials have shown this procedure to be safe and feasible a VATS approach for lobectomy has not been widely used yet. Surgeons can go beyond this limit by following a specific operative plan focused on learning the minimally invasive technique in centers of excellence and then including: a pre-operative phase based on the radioclinical assessments and an operating phase designed to develop a methodical approach to VATS technique...

Lung cancer is the most common cancer that cannot be ignored and cause death with late health care. Currently, CT can be used to help doctors detect the lung cancer in the early stages. In many cases, the diagnosis of identifying the lung cancer depends on the experience of doctors, which may ignore some patients and cause some problems. Deep learning has been proved as a popular and powerful method in many medical imaging diagnosis areas. In this paper, three types of deep neural networks (e.g., CNN, DNN, and SAE) are designed for lung cancer calcification...

Elastin is a unique protein providing deformability and resilience to dynamic tissues, such as arteries and lungs. It is an absolute basic requirement for circulation and respiration. Elastin can be degraded by elastases and has a high calcium affinity. Elastin calcification and elastin degradation are two pathological processes that impair elastin's functioning. Furthermore, elastin degradation can be associated to elastin calcification. Matrix Gla Protein (MGP) is probably the most potent natural inhibitor of elastin calcification and requires vitamin K for its activation...

RATIONALE: Pulmonary hamartomas are the most common benign tumor of the lung. Two types of pathologically similar hamartomas exist based on their location. These tumors have a low incidence, are rarely reported and frequently misdiagnosed because of lack of familiarity and/or understanding concerning their imaging features. PATIENT CONCERNS: Seventeen patients received treatment between June 2007 and May 2013 and had complete medical records. All of them had different degrees of cough and expectoration...

BACKGROUND: To evaluate the added clinical value of (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scans to chest CT imaging in predicting the conversion to thoracotomy during video-assisted thoracoscopic surgery (VATS) lobectomy in patients with lung cancer. METHODS: This is a retrospective study of 235 consecutive patients who underwent planned VATS lobectomy for primary lung cancer between 2011 and 2015. CT images were interpreted in terms of the presence and the attenuation of peribronchial lymph nodes (PLN) and peribronchial cuffs of soft (PCS) tissue, pleural calcification, and parenchymal calcified nodule...

Accelerated elastin degradation is an important pathogenic mechanism in chronic obstructive pulmonary disease (COPD) leading to irreversible lung function loss and cardiovascular comorbidities. The rate of elastin breakdown is a predictor of mortality in patients with COPD. Decelerating elastinolysis might be an attractive therapeutic target in this debilitating condition. Vascular calcification starts in the elastin network of the arterial wall and is enhanced in patients with COPD. Elastin calcification is accompanied by an upregulation of matrix metalloproteinase gene expression and consequently a shift in the elastase/anti-elastase balance towards degradation...

We report a case of metastatic pulmonary calcification in a patient with chronic renal failure on hemodialysis and secondary hyperparathyroidism. The diagnosis was made by using a probe-based confocal endomicroscopy which showed specific structures in the lung tissue and was proven by a transbronchial lung biopsy. To the best of our knowledge, this is the first reported case of the confocal endomicroscopy findings in a patient with metastatic pulmonary calcification.

Tuberculosis is a highly prevalent disease in India. It has a myriad of presentations. Usually pleural tuberculosis occur secondary to pulmonary tuberculosis which can manifest as pleural effusion leading to pleural calcification. Primary pleural calcification due to tuberculosis is an extremely rare manifestation of active tuberculosis. We present a case of a 21-year-old female presenting with fever, cough, weight loss and loss of appetite who was diagnosed to have pleural calcification due to primary tuberculosis...

BACKGROUND: Primary localized amyloidosis presenting as an isolated mediastinal mass is extremely rare, especially in the thymus. Sclerosing thymoma is also an extremely rare anterior mediastinal tumor, pathologically characterized by extensive sclerotic lesions with hyalinization and calcification. Only 14 cases of sclerosing thymoma and five cases of thymic amyloidosis have been reported to date. CASE PRESENTATION: A 78-year-old Japanese woman was diagnosed as having sclerosing thymoma (Masaoka stage IVa pericardial dissemination)-like thymic amyloidoma...

A 19-year-old woman, with normal kidney function, was diagnosed as having visceral calciphylaxis, especially diffuse breast and lung calcification. The calcification findings were clearly shown on CT, and bone scintigraphy revealed diffuse uptake in the thoracic area. Although there was no standard therapeutic approach for this clinical setting, the patient received empiric therapy with sodium thiosulfate. After 5 months of consecutive therapy, the calcification condition had a striking regression.

Giant cell tumors (GCTs) are aggressive benign lesions that occur in the bone epiphysis. They are most often found in the long bones of the lower extremities. Wrist bone involvement is rare, capitate bone involvement exceedingly rare. Treatment in the wrist usually consists of excision, local adjuvant treatment, and cementing and/or bone grafting. GCTs also metastasize to the lungs; pulmonary lesions are excised and systemic therapy provided. We present the case of a 19-year-old woman with GCT of the capitate bone...

Zhen Huang, Lele Wu, Linxi Chen
Apelin is an endogenous ligand of seven-transmembrane G protein-coupled receptor APJ. Apelin and APJ are distributed in various tissues, including the heart, lung, kidney, and even in tumor tissues. Studies show that apelin mRNA is highly expressed in the inner stripe of kidney outer medulla, which plays an important role in process of water and sodium balance. Additionally, more studies also indicate that apelin/APJ system exerts a broad range of activities in kidney. Therefore, we review the role of apelin/APJ system in kidney diseases such as renal fibrosis, renal ischemia/reperfusion injury, diabetic nephropathy, polycystic kidney disease, and hemodialysis (HD)...

In computed tomographic (CT) images of humans, decreased lung attenuation, bronchial dilation, and/or thickening, air trapping, cysts, and thickened interlobular septa have been associated with increasing age. To determine if there are differences in the CT appearance of the lungs of young and old dogs that could affect interpretation of diagnostic studies, pulmonary CT images of dogs with conditions unrelated to the thorax were reviewed retrospectively in a case-control study. Computed tomography studies of 42 young dogs (range 0...

Infliximab therapy is associated with higher rates of active tuberculosis (TB), particularly extrapulmonary and disseminated forms with unusual symptoms. We report the case of a 66-year-old man with Crohn's disease who developed TB mimicking lung cancer on imaging. He presented with cough and fever of 2 weeks' duration shortly after starting infliximab. Computed tomography of the chest revealed a 7.0 × 3.2 cm(2) pleural-based mass, highly suspicious for malignancy. Histopathological examination confirmed the diagnosis of TB...

Hypocalcemia is relatively uncommon paraneoplastic syndrome. Only one case of hypocalcemia has been reported in a patient with chondrosarcoma. We herein report a case of a 32-year-old woman with metastatic chondrosarcoma with tetany. Her imaging findings revealed multiple calcific metastatic lesions in the lungs, pancreas, left atrium, and pulmonary vein. A laboratory examination showed hypocalcemia with no evidence of any other disease that could induce hypocalcemia. On the basis of the laboratory and clinical findings, we concluded the etiology of her severe hypocalcemia to be excessive calcium consumption by the tumor itself...
