Scintigraphic assessment of patellar vascularity in total knee replacement surgeries following lateral release |
p. 54 |
Padma Subramanyam, P Shanmuga Sundaram, Narasimha Rao DOI:10.4103/2231-0770.102277 PMID:23826547For a total knee replacement (TKR) to function well, the patella must track centrally in the trochlear groove. Lateral retinacular release (LR) is performed as an integral step in TKR to avoid maltracking. Patellar resurfacing and infra patellar fat pad excision are other small surgical procedures performed during TKR that can also easily deprive the patella of its vascularity. A three phase bone scan helps in the assessment of patellar vascularity. Literature review reveals a variable association (10-56%) of LR and patellar hypovascularity in Caucasians. Objective: LR release done in TKR is known to compromise patellar viability, while its extent and severity is still debated. Our prospective study was undertaken to evaluate the effects of LR on patella along with other variables like patellar resurfacement, fat pad excision, patelloplasty on knees by 99m Technetium labeled methylene diphosphonate ( 99m Tc MDP) three phase bone scintigraphy (TBS). Materials and Methods: 45 TKRs were done between Jan 05 and Jan 06. Of them, 15 patients (21 knees) of primary TKR were considered prospectively. Patients undergoing uni/bilateral TKR due to symptomatic knee osteoarthritis were only selected for this study. Pre- and immediate postoperative TBS was done with modified positioning of knee joints (adducted, externally rotated and flexed to 30°) to visualize patellae away from knee joint, which otherwise gets superimposed on the femoral condyles. A follow-up TBS at 8-10 weeks was done in patients showing immediate post-op patellar hypovascularity. Results: 12/21 knees (57%) needed LR. Of these 12 knees, 8 (66%) showed hypovascularity; whereas 9 knees with no LR, 1 knee showed hypovascularity. All 9 knees (8 post LR+1 without LR) with hypovascularity underwent TBS again at 8-10 weeks and were found to show improvement in their vascularity status in all cases. Conclusion: Our study showed a higher incidence of LR in our population (57%). Association of LR and patellar ischemia was significant, about 16 times the risk. MDP bone scintigraphy is the only objective tool to quantify patellar vascularity. Overall 42.8% knees post-TKR had a transient patellar ischemia, and 38% of them were following LR. All of them recovered at 8-10 weeks postoperatively. |

Membranous nephropathy: Treatment outline and risk stratification |
p. 60 |
Ziad Arabi DOI:10.4103/2231-0770.102278 PMID:23826548Membranous nephropathy (MN) is the most common cause of nephrotic syndrome in adult. However, the exact etiology and the best treatment approach are still unclear. It is imperative to understand the nature of and prognosis of MN before initiating treatment which may include disease specific therapy based on a careful risk-stratification approach. |

Atrial fibrillation post cardiac bypass surgery |
p. 65 |
Ashraf Mostafa, Mohamed A EL-Haddad, Maithili Shenoy, Tushar Tuliani DOI:10.4103/2231-0770.102280 PMID:23826549Atrial fibrillation occurs in 5-40% patients after coronary artery bypass graft surgery. Atrial fibrillation increases mortality and morbidity in the post-operative period. We sought to conduct a comprehensive review of literature focusing on pathophysiology, risk factors, prevention and treatment of post coronary artery bypass graft atrial fibrillation. |

Trastuzumab for Her2/neu-positive metastatic salivary gland carcinoma: Case report and review of the literature |
p. 71 |
Belal Firwana, Bassel Atassi, Rim Hasan, Nour Hasan, Ammar Sukari DOI:10.4103/2231-0770.102282 PMID:23826550Salivary gland carcinomas metastasize to distant organs in 20% of salivary gland malignancies. Applying immunohistochemistry (IHC) measures, salivary gland tumors showed a wide range of oncogene markers expression, including the human epidermoid receptor 2 (Her2/neu), which could be targeted with monoclonal antibody. Treating salivary gland tumors, which have Her2/neu over-expression, with trastuzumab was reported in a few case reports. We report a 61-year-old Caucasian male, with a history of salivary gland tumor, who presented after 20 years of complete surgical resection with kidney mass. He was treated as primary renal cell carcinoma, unclassified, with nephrectomy and adjuvant clinical trail where he received placebo. Subsequently, he developed multiple hepatic lesions and retroperitoneal mesenteric lymphadenopathy; CT-guided biopsy revealed adenocarcinoma with Her2/neu, 3+ by IHC. The patient was treated successfully with trastuzumab with near-complete response. |

Myxoinflammatory fibroblastic sarcoma of the thigh: A morphologic diversity |
p. 74 |
Vanisri H Raghavan, Suchitha Satish, Sunila Ravishankar, Gubbanna V Manjunath DOI:10.4103/2231-0770.102283 PMID:23826551Myxoinflammatory fibroblastic sarcoma (MIFS)/acralmyxoinflammatory fibroblastic sarcoma (AMFS) is a rare, painless, low-grade neoplasm which commonly occurs in the extremities. It has a distinctive morphology and can be a diagnostic challenge, simulating inflammatory conditions as well as neoplastic conditions. They are low-grade sarcomas with a protracted clinical course, a high rate of local recurrence and a low rate of metastasis. We report a case of proximal MIFS in a 50-year-old woman who presented with a mass in the thigh. |
