RESUMEN
BACKGROUND: Juvenile idiopathic arthritis (JIA) is a childhood autoimmune disease that causes swelling and pain in at least one joint. Young people with JIA experience symptoms that persist into adulthood, and thus will undergo a transition including the o transfer of care from a pediatric rheumatologist an adult rheumatologist. Missing from the literature is research that centres the transition experience of young people with JIA in Canada. This goal of this patient-led research was to explore the experience young people with JIA through the process of transition. METHODS: Qualitative study using the Patient and Community Engaged Research (PaCER) approach. Trained patient-researchers conducted three focus groups using the Set, Collect and Reflect PaCER process. Participants, recruited via purposive and snowball sampling using research/personal networks and social media, were young people with JIA in Canada between 18 and 28 years who had experienced with the process of transition to adult care. Recordings were transcribed verbatim. Patient researchers individually coded overlapping sections of the data, and thematic analysis was conducted. RESULTS: In total, nine individuals participated in one or more focus groups. Three themes were identified, with sub-themes: preparedness for transition (readiness for the transfer of care, developing self-advocacy skills), continuity and breadth of care (changing relationships, culture shock, new responsibilities), need for support (social support, mental health support, and ongoing support needs - beyond the transfer of care. Peer support was a connecting concept in the support sub-themes. Transition was more than a change in primary physician but also a change in the care model and breadth of care provided, which was challenging for young people especially if they had insufficient information. CONCLUSIONS: Transition from pediatric to adult care in rheumatology is a significant period for young people living with JIA, and this patient-led study provided insight into the experience from the perspective of young people with JIA which is critical to informing the development of supports for patients through the process. Patients, caregivers, pediatric and adult rheumatologists and members of the multi-disciplinary care team need to collaborate in terms of resources preparing for transfer, and support throughout the transition process to ensure a successful transition process.
RESUMEN
Tension pneumothorax is a life threatening condition that occurs when the intrapleural pressure exceeds atmospheric pressure. It requires prompt diagnosis and immediate treatment. Tension pneumothorax developing postoperatively after cardiac surgery is not uncommon but occurrence in the operating room during cardiac surgery is rare. We report a case of tension pneumothorax intraoperatively during off pump coronary artery bypass grafting.
RESUMEN
A 63 years old patient with severely impaired pulmonary function presented with bilateral lower limb vascular blockade and was operated for emergency aortobifemoral bypass. The patient was considered to be at very high risk for general anesthesia but doing the case under regional anesthesia was also challenging because of the multiple dermatomal levels needed to be anesthetized and because of the potential of adverse effects with such extensive block. There are only a few reported cases of using combination of central neuraxial blocks. The procedure was successfully performed using combined high thoracic and lumbar epidural blockade with two different local anesthetics to minimizing toxicity and observing no adverse effects related to anesthesia technique.
RESUMEN
Sarcomatous lesions of the mediastinum usually present as aggressive and multicentre masses often attached to adjoining structures including heart and lungs. A forty one year male diagnosed with sarcomatous lesion in mediastinum presented for biopsy through midsternotomy later confirmed as angiosarcoma on histopathology. Patient bled excessively after surgery and required reopening of the chest. However, bleeding could not be controlled with reopening, blood products and packing of the mediastinal cavity. Bleeding could only be controlled by using recombinant activated factor VII as rescue therapy without any adverse effects.
RESUMEN
Valvular heart disease is a leading cause of morbidity and mortality in India. Advances in both surgical and percutaneous techniques and a better understanding of timing for intervention accounts for the current increased rates of survival. Echocardiography remains the gold standard for diagnosis and periodic assessment of patients with valvular heart disease. Generally, patients with stenotic valvular lesions can be monitored clinically until symptoms appear and most can now benefit from percutaneous techniques. In contrast, patients with regurgitant valvular lesions require careful echocardiographic monitoring for left ventricular function and may require surgery even if no symptoms are present. Percutaneous therapy of valvular regurgitant lesions is yet to evolve fully.

We sought to determine the rate of healthcare-associated infection (HCAI), microbiological profile, bacterial resistance, length of stay (LOS) and excess mortality in 12 ICUs of the seven hospital members of the International Infection Control Consortium (INICC) of seven Indian cities. Prospective surveillance was introduced from July 2004 to March 2007; 10 835 patients hospitalized for 52 518 days acquired 476 HCAIs, an overall rate of 4.4%, and 9.06 HCAIs per 1000 ICU-days. The central venous catheter-related bloodstream infection (CVC-BSI) rate was 7.92 per 1000 catheter-days;the ventilator-associated pneumonia (VAP) rate was 10.46 per 1000 ventilator-days; and the catheter-associated urinary tract infection (CAUTI) rate was 1.41 per 1000 catheter-days. Overall 87.5% of all Staphylococcus aureus HCAIs were caused by meticillin-resistant strains, 71.4% of Enterobacteriaceae were resistant to ceftriaxone and 26.1% to piperacillin-tazobactam; 28.6% of the Pseudomonas aeruginosa strains were resistant to ciprofloxacin, 64.9% to ceftazidime and 42.0% to imipenem. LOS of patients was 4.4 days for those without HCAI, 9.4 days for those with CVC-BSI, 15.3 days for those with VAP and 12.4 days for those with CAUTI. Excess mortality was 19.0% [relative risk (RR) 3.87; P < or = 0.001] for VAP, 4.0% (RR 1.60; P=0.0174) for CVC-BSI, and 11.6% (RR 2.74; P=0.0102) for CAUTI. Data may not accurately reflect the clinical setting of the country and variations regarding surveillance may have affected HCAI rates. HCAI rates, LOS, mortality and bacterial resistance were high. Infection control programmes including surveillance and antibiotic policies are a priority in India.

The incidence of thrombophlebitis following the use of two types of cannulae, a new generation polyurethane cannula Biovalve PUR and a polyurethane hybrid co-polymer Vialon cannula, was compared in a randomised trial. Seventy patients scheduled for elective cardiac surgery were randomly assigned to have either a Biovalve cannula or a Vialon cannula inserted before induction of anaesthesia. Postoperatively, the cannulae were removed either as soon as signs of thrombophlebitis were observed or at the end of seven days, whichever was earlier. There was a significantly lower incidence of thrombophlebitis in the Biovalve PUR group (17%) compared to the Vialon group (60%) at the end of seven days (p < 0.001). None of the cannulae tip cultures resulted in the growth of micro-organisms. There was also a lower incidence of the need for re-siting with the Biovalve than with the Vialon cannulae.

Chryseobacterium meningosepticum is a gram negative rod widely distributed in nature. It is known to cause meningitis in neonates and premature infants. Adult infections are not common and are usually nosocomially acquired. We report an unusual case of native valve endocarditis in a 58-year-old man due to this organism. A high degree of suspicion and correct identification and sensitivity testing is required to diagnose infections by this rare isolate.

Robotically enhanced telemanipulation surgery is a rapidly developing technique which enables totally endoscopic cardiac surgery with utmost precision and perfection on both beating heart and arrested heart. Between December 2002 and September 2006, 268 patients underwent robotically enhanced coronary artery bypass surgery using the da Vinci telemanipulation system. Fourteen patients underwent total endoscopic coronary artery bypass surgery. Of these 12 were performed on a beating heart and 2 on an arrested heart. Two-hundred and fifty-four patients had endoscopic takedown of the internal mammary artery followed by minimally invasive direct coronary artery bypass in 193 patients and left anterolateral thoracotomy in 61 patients. The internal mammary artery mobilization time was 36 min (28-76 min) and the left internal mammary artery to left anterior descending artery anastomosis time ranged from 20 to 36 min for the totally endoscopic coronary artery bypass patients. The right internal mammary artery of one patient was anastomosed to diagonal artery totally endoscopically. The mean internal mammary artery flow by Doppler measurement in patients undergoing minimally invasive direct coronary artery bypass was 58 ml min(-1). Seven patients required conversion to median sternotomy and coronary bypass surgery on the beating heart. The mean intensive care unit stay was 1.2 days and the mean hospital stay 4.5 days. There was one in-hospital mortality. All 14 patients who underwent total endoscopic bypass surgery had coronary angiography 3 months later which showed 100% patency in 13 patients. One patient had 50% anastomotic narrowing for which coronary angioplasty was performed in the same sitting. By using telematic technology, a complete endoscopic anastomosis is possible in both single vessels and suitable double vessel disease patients. The use of robotics is now extended to achieve complete myocardial revascularization by harvesting both the internal mammary arteries and making a small thoracotomy for direct anastomosis also.
RESUMEN
BACKGROUND: Conventional cardiovascular risk factors (CVRFs) are known to influence short-term and long-term outcome following coronary artery bypass graft surgery (CABG). There has been recent increase in prevalence of CVRFs in general population in India. However no information is available regarding the prevalence of same in patients undergoing CABG. METHODS AND RESULTS: In this cross-sectional study, one thousand consecutive patients undergoing elective CABG were included and data on major CVRFs was obtained in them. Mean age of the patients was 59.73 +/- 9.5 years and 884/1000 (88.4%) patients were males. 505/994 (50.8%) patients had BMI > or = 25.0 kg/m2 and 747/994 (75.2%) had BMI > or = 23.0 kg/m2. Diabetes mellitus was present in 475/1000 (47.5%) patients (46.5% men and 55.2% women), hypertension in 709/1000 (70.9% overall; 70.8% men and 71.6% women) and dyslipidemia in 781/913 patients (85.6% overall; 84.5% men and 93.9% women). 213/913 (23.3%) patients had LDL > or = 100mg/dl, 662/913 (72.5%) patients had low HDL and 338/913 (37.0%) patients had elevated triglycerides. 199/1000 (19.9%) patients (18.7% men and 29.3% women) had family history of premature CAD and 545/1000 (54.5%) patients (53.4% men and 62.9% women) had at least one family member having CAD (irrespective of the age of onset). 94/1000 (9.4%) patients (10.4% men and 1.7% women) were current smokers and another 302/1000 (30.2% overall; 33.7% men and 3.4% women) had history of smoking in the preceding one year. 876/913 (95.9%) of all the patients had at least one of the five major CVRFs and only 37/ 913 (4.1%) patients (4.1% men and 4.3% women) were free of all these risk factors. Sixty-one of the 1000 patients (6.1%) were younger than 45.0 years of age. As compared to older patients, dyslipidemia, family history of premature CAD and smoking were commoner in patients less than 45 years of age. In contrast, diabetes and hypertension were more prevalent in the older individuals. CONCLUSIONS: The present study showed high prevalence of most of the conventional CVRFs, esp. diabetes, hypertension and dyslipidemia in Indian population undergoing CABG.

BACKGROUND: Robotically enhanced telemanipulation surgery is a fast developing technique which allows totally endoscopic cardiac surgery with utmost precision and perfection on both beating heart as well as arrested heart. METHODS AND RESULTS: Between December 2002 and February 2004, 125 patients underwent robotically enhanced coronary artery bypass surgery using the da Vinci telemanipulation system (Intuitive Surgical Inc., California). Eleven patients underwent totally endoscopic coronary artery bypass surgery. Of them 9 were done on beating heart while 2 were done on arrested heart. One hundred and fourteen patients had endoscopic takedown of internal mammary artery followed by minimally invasive direct coronary artery bypass in 63 patients and left anterolateral thoracotomy in 51 patients. The internal mammary artery mobilization time was 42 min (35-74 min) while the left internal mammary artery to left anterior descending artery anastomosis time ranged from 20 to 36 min for the totally endoscopic coronary artery bypass patients. In 1 patient, the right internal mammary artery was anastomosed to diagonal artery totally endoscopically. The mean internal mammary artery flow by Doppler measurement done in patients undergoing minimally invasive direct coronary artery bypass was 64 ml/min. Seven patients required conversion to median sternotomy and coronary bypass surgery on beating heart. The mean intensive care unit stay was 1.2 days and the mean hospital stay 4.5 days. There was 1 in-hospital mortality. All 11 patients who underwent totally endoscopic bypass surgery had coronary angiography done at 3 months interval which showed 100% patency in 10 patients while one patient had 50% anastomotic narrowing for which coronary angioplasty was done in the same sitting. CONCLUSIONS: Using telematic technology, a complete endoscopic anastomosis is possible in both single vessel and suitable double vessel disease patients. The use of robotics is now extended to achieve complete myocardial revascularization by harvesting both the internal mammary arteries and making a small thoracotomy for direct anastomosis as well.

BACKGROUND: The radial artery is being used as a conduit of choice over saphenous vein with increasing frequency. We analyzed early and midterm results of coronary artery bypass grafting using radial artery as one of the conduits. The functional outcome of the hand after radial artery harvesting was analyzed. METHODS: The radial artery was used in 3,977 patients undergoing coronary artery bypass grafting between December 1996 and November 2000. Modified Allen's test was performed preoperatively in the ward and pulse oxymetry was used in the operating theater to assess the collateral circulation of the hand. A total of 4,172 anastomoses were performed using a radial artery. The patients were followed up at regular intervals in the outpatient clinic or were sent questionnaires. The functional results of the hand were assessed. Follow-up angiography was performed in 104 patients at a mean of 18 months. RESULTS: The hospital mortality was 0.8%. Perioperative myocardial infarction occurred in 1.3% of patients. The average number of grafts was 3.12. No patient had acute ischemic injury of the hand. Follow-up was complete in 94% of patients. Late infection developed in 0.4% of patients. Numbness and paresthesias continued in 6.5% and 3% patients, respectively, after 3 months. The patency rate of the radial and left internal mammary artery was 92.3% and 96.0%, respectively, at a mean of 18 months. CONCLUSIONS: Use of radial artery for coronary artery bypass grafting is associated with low morbidity and good functional outcome of the hand. It can be used more frequently as the conduit of choice after the internal mammary artery.

BACKGROUND: Perioperative stroke is a devastating complication after coronary artery bypass grafting (CABG). The reported incidence of neurologic complications after conventional CABG is 3% to 7%. With improved monitoring and surgical techniques, we have been able to achieve a drastic reduction in the stroke rate in our institution. This study evaluates the incidence of neurologic sequelae in patients who underwent off-pump CABG. METHODS: Over a 10-year period from January 1990 to September 2000, off-pump coronary artery bypass (OPCAB) operation was performed on 2,800 patients of the 18,037 patients undergoing CABG during that time frame at the Escorts Heart Institute and Research Centre. Initially, OPCAB was performed selectively in the high-risk group of patients (atheromatous aorta, renal impairment, chronic obstructive pulmonary disease, octogenarians, etc). Lately we performed multivessel OPCABs electively in about 60% to 65% of the patients undergoing CABG. Results. Mean age of the patients was 58.0 +/- 9.91 years (range 27 to 85 years) and mean number of grafts was 2.9 per patient. Neurologic complications (stroke/transient ischemic attack) occurred in 0.14% of patients. Overall hospital mortality in OPCAB patients was 2.14%, whereas mortality from neurologic complications was 0.07%. Predicted mortality (National Society of Thoracic Surgeons Cardiac Surgery Database Risk Model for CABG) for the entire patient group was 3.86% (p < 0.001). Conclusions. Although current techniques of monitoring and surgical procedures have significantly reduced the risk of stroke from CABG, our data strongly support OPCAB as a technique to further reduce stroke after CABG, especially in the high-risk group of patients.

BACKGROUND: The feasibility of off-pump coronary artery bypass surgery has been well demonstrated. The purpose of the present study was to assess the safety and efficacy of off-pump coronary artery surgery in patients with left main coronary artery disease. METHODS AND RESULTS: Between January 1997 and December 2000, 174 patients with significant left main coronary artery stenosis underwent coronary artery bypass grafting without a pump. During the same period, 991 patients who also had significant left main coronary artery stenosis underwent coronary artery surgery on a pump. The patients in the two groups were matched in preoperative variables except that those in the off-pump group were slightly older, and more required urgent surgery. Hospital mortality was 2/174 and 21/991 in the off-pump and on-pump groups, respectively (p=0.560). The incidence of perioperative myocardial infarction (1.74 v. 14/991, p=0.712), atrial fibrillation (17/174 v 157/991, p=0.050) and blood transfusion requirement (63/174 v. 476/991, p=0.05) were significantly less in the off-pump group. The intubation time (15+/-3 hours v 22+/-4 hours, p=0.001), blood loss (365+/-61 ml v 582+/-76 ml, p<0.001), intensive care unit stay (23+/-10 hours v. 36+/-11 hours, p<0.001) and hospital stay (6+/-4 days v. 9+/-5 days, p <0.001) were also less in the off-pump group. CONCLUSIONS: Off-pump coronary artery bypass surgery is safe and effective for patients with left main coronary artery disease.

Ventilation in the prone position, initially introduced in respiratory therapy to improve the drainage of secretions, has been used in intensive care to improve oxygenation. We report a case of an obese male patient who underwent elective coronary artery bypass grafting and had low PaO2 in the postoperative period. The PaO2 improved whenever the patient was ventilated in the prone position. On each occasion, oxygenation improved without any change in the hemodynamic parameters. The PaO2 increased from 57.8 to 249.7 mmHg on the first occasion, from 48.7 to 194.6 mmHg on the second and 62.5 to 199.7 mmHg on the third at an FIO2 of 1.0. The shunt fraction (Qva/Qt) decreased from 43.6% to 7.2% on the first occasion and from 46.7% to 12.5% on the second. Ventilation in the prone position can be an effective method for improving oxygenation in patients suffering from postoperative acute respiratory failure who are not responding to other ventilatory strategies.

OBJECTIVE: To compare continuous thoracic epidural analgesia (TEA) and paravertebral block (PVB) for postoperative analgesia in patients undergoing minimally invasive direct coronary artery bypass (MIDCAB) surgery for quality of analgesia, complications, compliance to chest physiotherapy, hemodynamics, and respiratory effects. DESIGN: Prospective, randomized study. SETTING: Specialty research hospital. PARTICIPANTS: Forty-one consenting patients undergoing MIDCAB surgery. INTERVENTIONS: Patients in the TEA group had an epidural catheter inserted at the T4-5 interspace, whereas patients in the PVB group had a catheter inserted in the paravertebral space on the left side at the T4-5 level. MEASUREMENTS AND MAIN RESULTS: Parameters evaluated included visual analog scale pain scores at rest and while coughing, supplemental analgesic requirement, complications, hemodynamics, and respiratory parameters. Measurements were made at 2-hour intervals for 12 hours beginning at 10 minutes after endotracheal extubation. There was no statistically significant difference in visual analog scale scores and requirement of supplemental analgesia between the 2 groups. Cardiac index at 4 hours and 6 hours was significantly higher in the TEA group. Patients in the PVB group had significantly lower respiratory rates at 8, 10, and 12 hours. All other parameters were comparable. In 1 patient, the epidural space could not be catheterized. One patient in the TEA group had transient hypotension, and 1 patient complained of backache at the site of the epidural catheter insertion. CONCLUSION: PVB is as effective as TEA for postoperative analgesia after MIDCAB surgery. PVB is technically easier than TEA and may be safer than TEA because no complications were seen in the PVB group.
