Simultaneous bilateral bullectomy and coronary artery bypass grafting through median sternotomy approach.

Lung bullae can severely compromise lung function. Smoking is an important cause of chronic obstructive pulmonary disease, as well as coronary artery disease and peripheral arterial disease. Significant diseases in the cardiovascular and thoracic systems may require multiple interventions apart from medical management. We discuss a patient in which simultaneous bilateral bullectomy and coronary artery bypass grafting were performed through the median sternotomy approach.

Resection of Mycotic Iliac Artery Aneurysm with Extra-Anatomic Bypass: An Alternative to Aneurysmorrhaphy in Difficult Situations.

Mycotic aneurysms of the iliac and other large arteries are rare and are associated with increased morbidity and mortality. Treatment of mycotic aneurysms usually requires modification of the surgical technique done for cases of degenerative or atherosclerotic aneurysms. Degenerative and atherosclerotic fusiform aneurysms are usually managed with aneurysmorrhaphy using a prosthetic graft, which however is not ideal for mycotic aneurysms. Avoidance of prosthetic material at the site of mycotic aneurysm is a better option with higher chances of resolution of infection and favorable patient outcome.

Ewing's sarcoma of kidney extending into IVC and RA: resection using modified cannulation strategy for CPB.

Ewing's sarcoma of the kidney is a rare tumor. Although renal carcinomas are known to involve the inferior cava, extension of the tumor up to the right atrium is not common. In the majority of cases when the tumor extends into the infrahepatic part of the inferior vena cava, it can be removed from the abdominal approach. Few patients require the use of cardiopulmonary bypass for removal of the tumor in the inferior vena cava and right atrium. The management of patients requiring resection of kidney tumors and right atrial mass is more complicated and requires a team approach consisting of oncosurgeons, cardiac surgeons, and cardiac anesthetists. The resection of the kidney tumor with a mass in the right atrium is usually done concomitantly. The cardiopulmonary bypass cannulation strategy needs to be modified in such cases.

Large mediastinal/thoracic benign teratoma presenting with haemoptysis: Report of a case and review of the literature.

The mediastinal teratomas can grow to a large size before becoming symptomatic. The symptoms are usually due to the compression of adjacent structures. A computed tomographic scan of the chest is the investigation of choice for making a provisional diagnosis and planning for further management. Removal of large mediastinal/thoracic teratoma can be associated with various intraoperative and postoperative complications, which can be life-threatening sometimes. We operated on a patient with a large mediastinal mass extending into the right thoracic cavity up to the costo-phrenic angle. The postoperative period was eventful and required judicious intensive care. The patient eventually recovered with conservative treatment. A literature search was done on PubMed using the keywords benign mediastinal teratoma. Case series/original articles published in the last two decades, that is, after the year 2000, were evaluated. As per the review of the literature, the prevalence of benign mediastinal teratoma may be higher in eastern countries. Thoracoscopic surgery is the preferred modality except for cases with adhesions or infiltration into surrounding structures.

Giant isolated iliac artery aneurysm with ipsilateral hydronephrosis treated with aneurysm resection and extra-anatomic bypass.

Isolated iliac artery aneurysms are rare and very rarely it may lead to hydronephrosis. The majority of uncomplicated iliac artery aneurysms can be managed with endovascular interventions but large complicated iliac artery aneurysms with compression on adjacent structures may require open surgery. We share our experience of a case of a large isolated iliac artery aneurysm with compression of the ureter probably leading to ureteric calculi and hydronephrosis on the ipsilateral side. The patient was managed with aneurysm resection and extra-anatomic bypass.

Styloid Process; Correlation Between Symptoms, Palpability and Measurements on Three Dimensional Computed Tomography.

Styloid process is a long and slender osseous projection protruding downward, forward and slightly medially from the temporal bone and serves as an anchor point for various muscles associated with the tongue and the larynx. The aim of the present study was to record the length and the angle of Styloid process on three dimensional computed tomography in patients with unilateral symptomatic and palpable styloid process and compare the length and the angle of styloid process of symptomatic side to asymptomatic side on three dimensional computed tomography. 3D-CT face reconstruction were perfomed in all 35 patients (17 females, 18 males of age range 25-69 years). The length of the styloid process and its angulation (transverse and sagittal angles) were measured by means of three dimensional and multiplanar reconstruction images. The length of styloid process on symptomatic side had a mean of 33.61 ± 5.08 mm while on asymptomatic side mean was 31.11 ± 5.02 mm. The mean transverse angle on symptomatic sides had a mean of 72.37° ± 4.48° while on asymptomatic side mean was 74.17° ± 4.48°. The mean sagittal angle seen on symptomatic side was 88.11° ± 5.21° while on asymptomatic side was 87.88° ± 5.03°. Symptomatic side has a longer styloid. Length of the styloid process has a statistical correlation with the symptoms and symptomatic side has a longer styloid. Though there was a difference in transverse and sagittal angulation in symptomatic versus asymptomatic side; but it was not statistically significant. On examination of the opposite asymptomatic side, 5 patients had a palpable styloid process therefore we infer that long styloid process may not always be associated with symptoms. Patients with cervicofacial pain should be evaluated for Eagle syndrome by palpation of styloid process in the tonsillar fossa and further by three dimensional computed tomography (3D-CT). 3D CT is an effective tool in evaluating patients with cervicofacial pain and making a diagnosis of Eagle's syndrome. Therefore, 3D CT should be performed while evaluating patients with these symptoms.

A novel sustained release drug-resin complex-based microbeads of ciprofloxacin HCl.

Objective A novel multiparticulate system for the gastro-mucoadhesive delivery of ciprofloxacin HCl (CFN) was developed with the help of ion-exchange resin to deal with urinary tract (UT) infections effectively. Materials and methods An optimized complex (resinate) of CFN with sodium polystyrene sulfonate USP resin was prepared and entrapped within microbeads of sodium alginate and pectin. The developed systems were evaluated for drug entrapment efficiency, percentage of mucoadhesion and in vitro release patterns in simulated gastric fluid (pH 1.2). Results and discussion The interaction of the resin complex and polycation via alginate was consequently supported the formation of polyelectrolyte complex membrane. The in vitro drug release studies demonstrate that formulation without drug-resin complex (NRB) released the drug more swiftly than formulation containing drug-resin complex (DRC). This controlled release pattern of drug, resin complex containing microbeads was owed to complexation between drug and resin. Conclusion Preliminary results from the study suggested that this drug-resin complex-entrapped microbeads can be used to incorporate other antibiotic drugs and could be effective against UT infection. Such developed formulation could be subjected to in vivo studies in future in order to prove their efficacy for such type of infections.

Evaluation of bowel wall thickening by computed tomography to differentiate benign from malignant lesions.

PURPOSE: Computed tomography(CT) is an excellent non-invasive modality to evaluate bowel wall thickening.The aim of our study was to evaluate CT appearance of bowel wall thickening due to various benign and malignant conditions taking into consideration pattern of attenuation, bowel wall thickness, extent of lesion, symmetry of lesion and other associated CT findings. MATERIALS AND METHODS: The prospective study was carried out on 50 patients who underwent computed tomographic evaluation of abdomen for suspicion of bowel pathology based on ultrasonography, barium studies and/or clinical grounds. The studies were conducted on Siemens ART and GE High speed CT scanners. The examination was performed as is done routinely for an abdominal scan with imaging done from diaphragm to pubic symphysis in supine position with the right lateral decubitus scans in selected cases for better characterization of gastric antral and duodenal lesions. Oral, rectal and intravenous (IV) contrast agents were administered. The diagnosis was confirmed by cytology or histopathology of any biopsy or surgical specimen. However, in cases where surgery was not done, diagnosis was confirmed by clinical response to medical treatment. RESULTS: Based on the various CT characteristics of abnormal bowel wall thickening, sensitivity and specificity of classifying a lesion as benign or malignant were calculated. Majority of the malignant bowel lesions were showing the following characteristics i.e. heterogeneous pattern of enhancement, marked bowel wall thickening, asymmetry of the lesion and focal/segmental bowel involvement. Overall, CT showed a sensitivity of 97% and specificity of 93% in differentiating between benign and malignant etiology of abnormal bowel wall thickening. CONCLUSION: Due to its high sensitivity and specificity, CT is an ideal imaging modality for differentiating between benign and malignant etiology of abnormal bowel wall thickening. Radiologists should be aware of the usefulness of specific CT criteria of bowel wall thickening to better differentiate benign lesions from malignant or potentially malignant lesions that warrant further diagnostic evaluation.
