Objective: This study was conducted to evaluate diffusion capacity of lung for carbon monoxide (DLCO) in patients with simple and complicated silicosis and to correlate abnormal findings detected, if any, with the computed tomography abnormalities in these patients.

Methods: This study included 56 patients with simple and complicated silicosis and without tuberculosis, in whom we performed DLCO as per standard technique. Various computed tomography findings, that is, presence, size and distribution of nodules associated with relative parenchymal and vascular markings, were recorded in the study subjects and classified into standard grading to be finally compared with DLCO.

Optical Coherence Tomography: An Eye Into the Coronary Artery.

Optical coherence tomography (OCT) is slowly but surely gaining a foothold in the hands of interventional cardiologists. Intraluminal and transmural contents of the coronary arteries are no longer elusive to the cardiologist's probing eye. Although the graduation of an interventionalist in imaging techniques right from naked eye angiographies to ultrasound-based coronary sonographies to the modern light-based OCT has been slow, with the increasing regularity of complex coronary cases in practice, such a transition is inevitable.

Middle Lobe Syndrome in Silicosis.

A case of silicosis presenting as middle lobe syndrome is described in a middle-aged female. The diagnosis was confirmed by both bronchoscopy and demonstration of right middle lobe lumen narrowing and compression by calcified hilar lymph nodes on computerized tomographic scan. Simultaneous occurrence of endobronchial silicosis and bronchial stenosis by enlarged calcified peribronchial lymph nodes causing middle lobe syndrome has not been described previously as reported in this case.

Adenocarcinoma lung presenting with meningeal carcinomatosis.

Meningeal infiltration by malignant metastasis process without brain parenchymal involvement is very unusual event in patients with bronchogenic carcinoma. This manuscript describes a case of adenocarcinoma right lung in a 48-year old male having persistent headache. The cerebrospinal fluid cytology revealed the presence of metastatic deposits of adenocarcinoma lung that confirmed the diagnosis of meningeal carcinomatosis.

Sphingosine kinases negatively regulate the expression of matrix metalloproteases ( and ) and their inhibitor genes via sphingosine 1-phosphate in extravillous trophoblasts.

Purpose: Extracellular matrix remodeling is essential for extravillous trophoblast (EVT) cell migration and invasion during placental development and regulated by matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteases (TIMPs). Sphingosine kinases (SPHK1 and SPHK2) synthesize sphingosine-1-phosphate (S1P), which works either intracellularly or extracellularly via its receptors S1PR1-5 in an autocrine or paracrine manner. The role of SPHKs/S1P in regulating the expression of MMPs and TIMPs in EVT is mostly unknown and forms the primary objective of the study.

Spontaneous expectoration of tumor tissue in primary adenocarcinoma lung.

Spontaneous expectoration of the tissue fragments in primary lung carcinoma is an extremely unusual event. Expectoration of tumor fragments is a significant event that should not be ignored as it serves itself as a noninvasive tool to diagnose underlying malignancy if such samples are immediately preserved and subjected to histopathological examination. More so, expectoration of a large-sized fragment may provide substantial relief from the breathlessness.

Utility of Image Guided Fine Needle Aspiration Cytology in Intra-Thoracic Lesions with Emphasis on Lung Cancer Detection.

Background And Aims: Fine Needle aspiration cytology has emerged as an essential pre-biopsy investigation to rule out or confirm malignancy in superficial as well as deep seated lesions. Radiological assistance has proved to be a blessing for obtaining adequate samples. With unwavering leading position of lung cancer in terms of incidence and mortality, it has become necessary to study the trends of our population and assess the usefulness of techniques aiding in early diagnosis.

The Effect of Aerosolized Chlorpheniramine Maleate on Exercise Induced Bronchospasm and Gas Exchange in Asthmatics.

Introduction: Exercise induced asthma (EIB) is an acute, reversible, usually selflimiting airways obstruction which sets in after exercise in patients with asthma. One popular mechanism of EIA is the increase in histamine and its metabolites in circulation after exercise, which leads to bronchoconstriction via histamine receptors in bronchi. Chlorpheniramine Maleate is potent, less sedative antihistaminic drug, which acts by inhibiting histamine release from mast cells.

A study on procedural delay in diagnosis and start of treatment in drug resistant tuberculosis under RNTCP.

Background: Multi-drug-resistant TB (MDR-TB) has become a significant public health problem and an obstacle to effective TB control. Rapid diagnostic tests for anti tubercular drugs sensitivity have significantly reduced total time in initiation of treatment. Still there is a significant gap between MDR diagnosis and start of category IV treatment.

Risk-Adjusted Analysis of Patients Undergoing Emergency Laparotomy Using POSSUM and P-POSSUM Score: A Prospective Study.

Background: Comparison of operative morbidity rates after emergency laparotomy between units may be misleading because it does not take into account the physiological variables of patients' conditions. Surgical risk scores have been created, and the most commonly used is the Physiological and Operative Severity Score for the enumeration of Mortality (POSSUM) or one of its modifications, the Portsmouth-POSSUM (P-POSSUM), usually requires intraoperative information.

Objective: The objective of this study is to evaluate the POSSUM and P-POSSUM scores in predicting postoperative morbidity and mortality in patients undergoing emergency laparotomy.
