RESUMO

BACKGROUND: Transplant renal artery stenosis (TRAS) may lead to graft dysfunction and failure. Progressive deterioration of renal allograft function may be exacerbated by contrast-induced nephrotoxicity during iodine contrast administration for renovascular imaging of allografts. We present our institutional experience of endovascular management for TRAS using CO2 digital subtraction angiography (CO2-DSA) and balloon angioplasty to manage failing renal transplants. METHODS: Four patients with renal allografts from March 2017-May 2018 were referred for graft dysfunction and pending renal transplant failure. Indications for referral included refractory hypertension, decreasing renal functioning, and elevated renovascular systolic velocities. RESULTS: Median age of the four patients was 41.5 years (22-60 years). There were two male and female patients. Chronic hypertension and type 2 diabetes mellitus were the most common comorbidities. An average total of 75 mL of CO2 was used, supplemented with 17.4 mL of iodinated contrast. All patients had improvements in renal function following intervention with a mean decrease in systolic and diastolic blood pressure of 25.8% and 21.4%, respectively. We also observed a mean decrease of BUN by 13.6% and creatinine by 37.4%. Additionally, eGFR increased by 37.7%. All allografts survived after surgery, and only one patient required repeat angioplasty for recurrence. CONCLUSIONS: CO2-DSA with balloon angioplasty can be successfully utilized to salvage deteriorating kidney allograft function in patients with TRAS.

RESUMO

OBJECTIVE: To compare the proportion of early postoperative infection in clean orthopedic surgery after single dose of prophylactic antibiotic and multiple doses of prophylactic antibiotic. DESIGN: Interventional quasi-experimental study. PLACE AND DURATION OF STUDY: Department of Orthopedics, Abbasi Shaheed Hospital, Karachi from April 2004 to March 2005. MATERIAL AND METHODS: Two hundred patients of either age and gender, undergoing clean orthopedic surgery were equally divided into two groups A and B. Group A was given single dose of prophylactic antibiotic, while group B was given multiple doses of prophylactic antibiotic. Follow-up period was 28 days. All cases were evaluated for postoperative wound infection. Sampling technique was non-probability convenience. RESULTS: Mean age was 35.51+/-20.79 years in group A and 26.17+/-19.79 years in group B. However, there was a significantly higher proportion of male patients in group B than in group A (p=0.006). Statistical analysis showed no significant difference in the proportion of early postoperative infection cases between the two groups(p=0.270). Staphylococcus aureus was the commonest organism cultured from the wound discharge in our study followed by E. coli. Eight of our cases having postoperative wound infection showed no growth, out of which 7 were superficial and 1 was deep. There was no significant difference between the two groups regarding mean operating time and duration of stay in hospital. CONCLUSION: There was no statistically significant difference in the proportion of early postoperative infection cases between the two groups.

RESUMO

OBJECTIVE: To compare the time of union, degree of shortening and angulations in coronal and sagittal plane in children after applying Thomas splint and early hip spica for the treatment of isolated closed femoral shaft fractures. DESIGN: Interventional quasi-experimental study. PLACE AND DURATION OF STUDY: Orthopedic department of Abbasi Shaheed Hospital, Karachi from December 2002 to January 2004. SUBJECTS AND METHODS: A 100 patients of either gender selected by non-probability convenience with closed unilateral femoral shaft fracture were equally divided into 2 groups. Group A was treated with Thomas splint and Group B with early hip spica casting. Above mentioned variables were noted in both groups. RESULTS: In group A, there were 60% (n = 30) males and 40% (n = 20) females. In group B, there were 62% (n = 31) males and 38% (n = 19) females. Mean age was 6.94 + 2.75 years in group A and 5.48 + 2.67 years in group B. Time of union, degree of shortening and angulations in coronal and sagittal plane were not significantly different in two groups. Duration of stay in hospital was 4.82 + 2.4 days in group A and 3.68 + 2.11 days in group B. CONCLUSION: Results comparable to early hip spica cast can be obtained with Thomas splint in children with isolated closed femoral shaft fracture.
