Sublobar resection and lobectomy have equivalent survival for patients with clinical stage IA non-small cell lung cancer in the context of computed tomography screening for lung cancer.

Bedside placement of PICC line by trained vascular nurses is an effective method with a high success rate, low malposition rate and requires minimal support from interventional radiology.

A systematic review of transesophageal echocardiography (TEE)-induced esophageal perforation was done using the MEDLINE (PubMed and OVID interfaces), Google Scholar and EMBASE databases. Thirty-five cases of esophageal perforation from 22 studies were analyzed. TEE-induced esophageal perforation occurs in elderly female patients, predominantly in an intra-operative setting. Thoracic esophagus is the most commonly involved segment, especially, when TEE is performed intra-operatively. Majority of the esophageal perforations occur in cases with a perceived low risk or smooth TEE exam and thus, screening for high risk factors may not eliminate the occurrence of a perforation. A delayed detection of perforation occurs when it is a thoracic esophageal perforation, performed intra-operatively and when there are no known preoperative risk factors. Shock during the detection of the perforation is associated with mortality. Majority of the perforations can be repaired primarily.

The frequency and extent of surgery for nonmalignant disease can be minimized in a CT screening program and provide a high cure rate for those diagnosed with lung cancer and undergoing surgical resection.

The plasma elastase level was measured as a marker of neutrophil degranulation in three groups, each of 15 patients, with uncomplicated varicose veins, lipodermatosclerosis (LDS) and venous ulceration. The values obtained were compared with those in age- and sex-matched control subjects. Significantly higher levels of elastase were found in all patient groups compared with controls: median 25.6 ng/ml for patients with uncomplicated varicose veins, 22.1 ng/ml for those with LDS, 26.0 ng/ml for those with venous ulceration. There was no difference in neutrophil count between the patient and control groups. These results provide evidence of increased neutrophil degranulation in patients with venous disease. The finding of raised elastase levels in all three patient groups shows that this was not due solely to the inflammatory process characterizing LDS and venous ulceration.

Primary epithelial myoepithelial carcinoma of lung is a rare entity and is thought to arise from the submucosal bronchial glands distributed throughout the lower respiratory tract. Because of the rarity of this tumor, we describe one case of epithelial myoepithelial carcinoma arising in the bronchus intermedius and presenting as an endobronchial mass. A 57-year-old male patient presented with an incidental finding of an endobronchial mass located in the lumen of the right lower lobe bronchus and caused near total luminal occlusion of the bronchus. An endobronchial carcinoid tumor was entertained clinically. Subsequently the patient underwent an uneventful videothoracoscopic lobectomy of lower and middle lobes of the right lung. Morphologically and immunohistochemically the tumor was characterized by two cell populations with epithelial and myoepithelial cells forming duct-like structure. The final diagnosis of epithelial myoepithelial carcinoma of lung was rendered.

Summary:Carcinoma of the transverse colon presenting as an abscess of the anterior abdominal wail is a rare occurrence. Such a case is presented, where all investigations failed to show the nature of the lesion. The literature has been reviewed and the pathology that characterizes such lesions, and their management in the light of their favourable prognosis, is discussed. Occult colonic carcinoma should be considered in the differential diagnosis of such abscesses.
