Blood stream infections can lead to life threatening sepsis and require rapid antimicrobial treatment. The organisms implicated in these infections vary with the geographical alteration. Infections caused by MDR organisms are more likely to increase the risk of death in these patients. The present study was aimed to study the profile of organisms causing bacteremia and understand antibiotic resistance patterns in our hospital. 1440 blood samples collected over a year from clinically suspected cases of bacteremia were studied. The isolates were identified by standard biochemical tests and antimicrobial resistance patterns were determined by CLSI guidelines. Positive blood cultures were obtained in 9.2% of cases of which Gram-positive bacteria accounted for 58.3% of cases with staph aureus predominance; gram negative bacteria accounted for 40.2% with enterobactereciea predominence; and 1.5% were fungal isolates. The most sensitive drugs for Gram-positive isolates were vancomycin, teicoplanin, daptomycin, linezolid, and tigecycline and for Gram-negative were carbapenems, colistin, aminoglycosides, and tigecycline. The prevalence of MRSA and vancomycin resistance was 70.6% and 21.6%, respectively. ESBL prevalence was 39.6%. Overall low positive rates of blood culture were observed.

Atherosclerotic renal artery stenosis (ARAS) is an important cause of kidney disease, accelerated hypertension (HTN), and its treatment is controversial. Our aim was to evaluate the outcomes, safety, and efficacy of percutaneous transluminal angioplasty (PTA) for ARAS. Retrospective analysis of ARAS was performed among 470 angiographies during 1995-2010. Patients with nonatherosclerotic RAS and renal transplant were excluded. We assessed preintervention and postintervention mean arterial pressure (MAP), antihypertensive medications, and renal function to classify as deteriorated (>10% increase in MAP/increase in drugs/>20% reduced GFR), improved (>10% reduced MAP/reduced drugs/>20% increased eGFR), or stabilized (<10% change in MAP/same antihypertensive drugs/<20% change in eGFR) at last follow-up. A total of 220 subjects with mean age of 57.6 ± 10.4 years underwent PTA and/or stenting. The average follow-up was 23.07 ± 21.2 months. Accelerated HTN, HTN onset >50 years, unexplained renal failure, and unilateral small kidney were the most common presentations. In all, 255 significant stenotic lesions in 220 patients (119 unilateral, 66 single functioning kidney, and 35 bilateral) were observed. In total, 255 PTA were performed, including 177 stenting. Technical success was seen in 220/243 (90.5%) subjects. Combined MAP and antihypertensive drugs improved in 154/220 (70%) patients. Renal function improved/stabilized in 175/220 (79.5%). Angioplasty and stenting are relatively safe and feasible tools for control of blood pressure (BP) in ARAS. Angioplasty produced improvement/stabilization of BP in 70%, and the renal function in 79.5% subjects.
