Abstract
Paragangliomas are neuroendocrine tumors similar to pheochromocytomas but arising from extra adrenal site. It is a very rare tumor in an intraoral site, we found a single case of intraoral paraganglioma in a literature, and hence as per our best knowledge this is only the second case of paraganglioma presented in an intraoral location. We present here a case report of paraganglioma on the ventral surface of the tongue. A 37 years old lady presented with a large asymptomatic swelling on the ventral surface of the tongue from one year. The past medical history and familial history were non relevant to the swelling. Surgical excision was performed and histopathological examination of the specimen revealed the diagnosis of extra adrenal paraganglioma. The case is being presented here for its rarity in an intraoral location.

Abstract
Juvenile nasopharyngeal angiofibroma (JNA) is a rare vascular tumour which is benign but locally aggressive and occurs invariably in young and adolescent males. It seldom involves the oral cavity but has the tendency to invade the adjacent structures. Its characteristic features include slow progression, aggressive growth & an increased rate of persistence and recurrence due to its location in inaccessible areas. In literature, very few cases of JNA have been reported with extension into the oral cavity. Here, a case of JNA with extension into the oral cavity has been discussed who reported to our institute.

Abstract
Condylar aplasia which means "failure of development" is a rare condition and can be unilateral or bilateral. Mandibular condylar Aplasia without any association with syndrome is extremely rare. Temporomandibular joint (TMJ) ankylosis results from trauma, infection and inadequate surgical treatment of the condylar area. Congenital cases are very rare. We report case of congenital unilateral aplasia of left mandibular condyle with ankylosis of right condyle, with an associated orthopedic deformity in a nine-year-old male patient, which may be a part of some unreported syndrome that has not been mentioned so far in literature. As per our best knowledge, no other case including such clinical features has been reported.

Abstract
Chickpea stunt disease caused by Chickpea chlorotic dwarf virus (CpCDV) (genus Mastrevirus, family Geminiviridae) is the most important biotic stress affecting chickpea crops worldwide. A survey conducted on the incidence of stunt disease clearly revealed high incidence of the disease with severe symptom expression in both indigenous and imported genotypes. To manage the disease in a sustainable way, resistant genotypes need to be bred by adopting objective and precise assessment of the disease response of chickpea genotypes. At present, evaluation of CpCDV resistance is conducted on the basis of natural infection in the field, which is bound to be erroneous due to vagaries in vector population. To circumvent the above problems, we devised an agroinoculation technique that involves the delivery of viral genomic DNA through Agrobacterium tumefaciens. An objective scoring system assigning quantitative value to different symptoms has been evolved to assess the response of chickpea genotypes to CpCDV inoculation. Using the inoculation and scoring techniques, we screened 70 genotypes, which helped in differentiating field resistance that is more due to resistance to vector feeding than resistance to the virus.

Abstract
Objective: To assess the effects of sodium valproate on intratesticular testosterone and lactic dehydrogenase level in rats. Methods: Male Wistar rats (12 weeks old) were treated with sodium valproate and sacrificed at the end of the 2nd, 4th, 5th, 7th, 10th and 15th week, after the last exposure to sodium valproate. The testes were removed, weighed and processed for biochemical analysis. Results: The intratesticular testosterone level was significantly (P<0.001) reduced in 200 mg/kg and 400 mg/kg treated rats. The intratesticular lactate dehydrogenase (LDH) level was significantly (P<0.001) increased by valproate in a time dependent manner. Conclusion: Valproate causes reversible change in intratesticular testosterone and LDH level.

Abstract
The presence of anomalies of the systemic and pulmonary venous connection associated with single ventricle anomalies has been considered a contraindication for the Fontan operation (FO). The aim of this study is to outline the technical considerations associated with the presence of anomalies of systemic and/or pulmonary venous connections and to identify the risk factors for mortality in this group of patients undergoing the modified FO. Between 1989 and 2004, 63 patients (median age, 3.2 years) with anomalous systemic or pulmonary venous connection underwent a Fontan procedure at our institution. Nine patients had a combination of anomalous systemic and pulmonary venous connection, 49 patients had anomalous drainage only from the systemic circulation, and 5 patients had isolated anomalies of pulmonary venous return. Visceral heterotaxy syndrome was diagnosed in 25 patients. Previous palliative operations had been performed in 51 patients (81%). There was 1 early death, and 2 patients required take down of Fontan procedures. Two patients required reoperation for revision of the atrial baffle. At a mean follow-up of 4.6 +/- 3.4 years, there have been 5 late deaths (8%) and 45 patients (71%) have undergone Fontan completion. Actuarial survival was 92% at 1 year and 91% at 5 and 10 years-not significantly different from the overall survival of the Fontan patients. We conclude that the modified FO can be successfully performed in patients with anomalous systemic or pulmonary venous connections, including those with visceral heterotaxy syndrome, with morbidity and mortality rates that do not differ significantly from those achieved in all patients with normal connections.

Abstract
BACKGROUND The objective of this study was to review our surgical strategy in children with double outlet right ventricle and to assess risk factors for early and late mortality and reoperation. METHODS Patients (n = 124; June 1980 to January 2000; age range, 7 days to 16 years; mean, 2.8 years) who underwent repair of double outlet right ventricle. The patients were divided into three groups. Group 1 (n = 47) had noncomplex patients with atrioventricular concordance, a single ventricular septal defect, balanced ventricles, no straddling atrioventricular valves, and no major pulmonary artery anomalies. Group 2 (n = 39) included patients with double outlet right ventricle and a subpulmonary ventricular septal defect (Taussig-Bing). Group 3 (n = 38) had patients with complex anomalies including straddling atrioventricular valves, atrioventricular septal defects or a hypoplastic valve or ventricle, or a combination of atrioventricular septal defects and hypoplastic valve or ventricle. RESULTS Four types of definitive repairs were performed: (1) intraventricular tunnel repair with a baffle from the left ventricle to the aorta (n = 53); (2) use of a valved or nonvalved conduit (n = 20); (3) arterial switch operation with a patch committing the left ventricle to the neo-aorta (n = 16); and (4) cavopulmonary shunt and Fontan procedures (n = 33). Two patients with late postoperative cardiomyopathy had heart transplantation. Potential risk factors included location of the largest ventricular septal defect, presence of additional ventricular septal defects, ventricular outflow obstruction or hypoplasia, or both ventricular outflow obstruction and hypoplasia, previous palliation, and type of definitive operation. There were six early deaths (4.8%) and four late deaths (3.2%), and two heart transplants (1.6%). Overall 15-year survival was 95.8%, 89.7%, and 89.5% for groups 1, 2, and 3, respectively (p = 0.08). Thirteen patients (11.4%) have required 15 reoperations. Mean follow-up for survivors was 76.6 +/- 52.8 months. Up-to-date follow-ups are available on 114 surviving patients. Ninety-five of these patients (83.3%) were in New York Heart Association class I, and the remaining 19 patients (16.7%) were in New York Heart Association class II. Freedom from reoperation was 87%, 72%, and 100% at 15 years for groups 1, 2, and 3, respectively (p = 0.11). CONCLUSIONS Survival was high for all patients with double outlet right ventricle undergoing intraventricular tunnel repair, arterial switch operation, and repair with a conduit or a modified Fontan procedure. Careful attention to preoperative anatomy dictates the best surgical approach and will enhance outcomes.

Abstract
Between 1993 and 2000, 50 patients (age range, 1 month to 18 years) who had left ventricular outflow tract (LVOT) disease and had undergone a Ross procedure were assessed using echocardiography. Aortic annulus size, valvular gradient, valve insufficiency, LV dimensions at end-systole and end-diastole, LV interventricular septal and posterior wall thickness, and LV mass index (LVMI) were measured. There was 1 early and 2 late deaths, and 5 reoperations. Aortic annulus size increased and degree of aortic insufficiency (AI) decreased, as did LV internal dimensions and LVMI. Peak pressure gradients declined from 73 +/- 18 mm Hg to 7 +/- 7 mm Hg, and LVMI regressed (167 +/- 6 g/m(2) v 108 +/- 6 g/m(2), P <.001) after 3 years. The degree of AI ranged from none to mild, and no patient has LVOT stenosis. Regression of LV dilatation and hypertrophy, good autograft valve function and durability, and a high survival rate suggest that the Ross procedure is preferred for most children who require aortic valve replacement.

Abstract
OBJECTIVES Truncus arteriosus (TA) continues to be associated with significant morbidity and mortality, but there have been clinically significant improvements with early repair. METHODS Sixty patients underwent physiological correction of TA between November 1978 and January 2000. The average age was 76 days (range, 3 days--20 months). Associated cardiac anomalies were frequently encountered, the most common being severe truncal valve regurgitation (n=7), interrupted aortic arch (n=6), coronary artery anomalies (n=6), non-confluent pulmonary arteries (n=4), and total anomalous pulmonary venous return (n=1). Truncal valve replacement was performed initially or subsequently in seven patients with severe regurgitation (mechanical prostheses in six patients and a cryopreserved aortic homograft in one patient). Right ventricle--pulmonary artery continuity was established with an aortic (n=16) or pulmonary homograft (n=32) in 48 patients, a Dacron polyester porcine valved conduit in five, a non-valved polytetrafluoroethylene (PTFE) tube in three, direct anastomosis to the right ventricle with anterior patch arterioplasty in three, and a bovine jugular venous valve conduit in one patient. RESULTS There were ten hospital deaths (17%; 70% confidence limit, 7--25%). Multivariate and univariate analyses demonstrated a relationship between hospital mortality and associated cardiac anomalies. In the 43 patients without these associated cardiac anomalies, the early survival was 91% (group I). In the 17 patients with one or more of these risk factors, the survival was 71% (group II, P=0.002). There was one late death. Twenty-three patients (46%) required reoperation for right ventricular outflow tract (RVOT) obstruction at a mean follow-up time of 59.1 months. In 23 patients, the RVOT reconstruction was performed with a PTFE monocusp, and six patients had of a variety of replacement conduits inserted. Postoperatively, there were 34 (68%) patients in New York Heart Association functional class I and 16 (32%) in class II. Twenty-eight surviving patients are reported as doing well without any medication. The freedom of reoperation in the 39 hospital survivors (group I) without risk factors was 64% at 7 years; and 36% at 10 years in the 11 patients (group II) surviving with risk factors. CONCLUSIONS Associated cardiac anomalies were risk factors for death after the repair of TA. In the absence of these associated lesions, TA can be repaired with an excellent surgical outcome in the neonatal and early infancy period.

Abstract
BACKGROUND Aortic valve replacement in children remains challenging because of constraints imposed by available prosthetic devices. Potential risks of anticoagulation with mechanical valves and degeneration of other biological substitutes have kindled interest in the Ross procedure. This study outlines the evolution of our 27-year experience with prosthetic devices. METHODS Ninety-nine patients who underwent aortic valve replacement (January 1973 through September 2000) were included in this study. Procedures included implantation of pulmonary autograft (PA) (n = 42), aortic homograft (AH) (n = 3), mechanical valves (MV) (n = 41), and xenograft tissue valves (XG) (n = 13). RESULTS The mean follow-up times were: 3.8+/-1.3 years for PA, 3.5+/-1.5 years for AH, 7.7+/-4.7 years for MV, and 8.4+/-4.8 years for XG. There were no significant differences in perioperative outcomes among the groups (p < or = 0.05) or early deaths (2 each in the MV, AH, and PA groups). The incidence of valve-related complications and reoperations was high in the MV (n = 5), XG (n = 7), and AH (n = 1) groups as compared with the PA group (n = 3, p < 0.01). Early and late mortality for the series was 8.6% (n = 8). Overall, the reoperation rate was 20.7% (n = 18): 15.2% (5 of 33) MV, 70% (7 of 10) XG, 50% (1 of 2) AH, and 11.9% (5 of 42) for PA. The actuarial survival rate was 87.8% and 100% at 10 years for MV and XG, and 95.2% and 6.6% at 7 years for PA and AH. CONCLUSIONS Aortic valve replacement in children can be performed with acceptable mortality and good long-term results. The Ross procedure, although more complicated, has the advantage of not requiring anticoagulation therapy, can be performed in all age groups, possesses inherent growth potential, and exhibits the most normal left ventricular outflow tract hemodynamics.

Abstract
Adrenomedullin (ADM) is a vasoactive peptide with potent dilatory effects. We studied whether perioperative myocardial injury could be altered by the presence of ADM. Blood samples from 19 children with congenital heart disease undergoing surgical repair were collected at six time points: preoperative, on cardiopulmonary bypass (CPB), and 0, 3, 6, and 12 hours after CPB. Blood levels of ADM (pg/ml) and troponin-I (Tn-I; ng/ml), a specific marker of myocardial injury, were measured. Patients were divided into three groups based on their 12-hour Tn-I levels (I, < 10, n = 6; II, 10-25, n = 6; III, >25, n = 7). Preoperative Tn-I levels were within the normal range for all patients. Preoperative ADM levels in group I (with little or no evidence of myocardial injury) were significantly greater than those of either group II or III (242.7 +/- 15.4 vs 83.8 +/- 18 and 85.2 +/- 5.5, respectively; p < or = 0.0001 for each). The 12-hour ADM levels in group I remained significantly lower than preoperative levels (242.7 +/- 15.4 vs 197.4 +/- 11.6, p < or = 0.03) but higher than in the other groups. In group III, ADM increased at the 12-hour time point (159.2 +/- 6.5, p < or = 0.0001 vs baseline). Higher preoperative ADM levels are associated with lower levels of myocardial injury (as assessed by troponin-I release) during congenital heart surgery.

Abstract
Human adrenomedullin (ADM), a peptide comprising 52 amino acids, is a circulating hormone with vasodilator properties. We have evaluated its release by the heart following ischaemic myocardial damage, as indicated by elevated levels of the cardiospecific protein troponin-T (Tn-T) during cardiopulmonary bypass. ADM (pg/ml) and Tn-T (ng/ml) were measured in coronary sinus blood before and after aortic cross-clamp and in venous blood 6 h after surgery in 22 coronary-bypass patients. Based on the pre- and post-clamp Tn-T levels in the coronary sinus, the patients were divided into group I (no change; n=10) and group II (two times increase; n=12). Baseline ADM (362.7+/-106.2 and 303+/-58.7 pg/ml in groups I and II respectively; means+/-S.D.) and Tn-T (0.66+/-0.14 and 0.57+/-0.13 ng/ml respectively) levels were similar in both groups. In group I, the post-clamp ADM (317.6+/-80.8 pg/ml) and Tn-T (0.68+/-0.15 ng/ml) levels did not change significantly. In group II, the post-clamp ADM levels rose significantly above the baseline, mimicking the change in Tn-T (ADM, 541.4+/-89.4 pg/ml; Tn-T, 1.37+/-0.31 ng/ml; P=0.009). After 6 h, the systemic Tn-T levels were similar in both groups (2. 09+/-0.44 and 1.95+/-0.52 ng/ml in groups I and II respectively). We suggest that: (1) minor degrees of myocardial ischaemic damage result in release of ADM by the heart, and (2) ADM may play a protective role in the myocardium during an ischaemic insult. This suggests a possible therapeutic role for ADM in the management of intra-operative myocardial ischaemia.

Abstract
BACKGROUND Noninvasive methodologies have shown poor sensitivity in predicting rejection when compared to serial endomyocardial biopsies. We studied the potential role of donor blood troponin T (Tn-T) as a marker for predicting heart transplant rejection. METHODS Blood cardiac Tn-T was measured from 16 heart donors. Transplant rejection and cardiac function in the recipients were monitored for 1 year. RESULTS When data were analyzed based on donor blood Tn-T levels, 6 patients who received hearts from donors with low Tn-T (<0.45+/-0.1 ng/mL) showed no rejection, and patients whose hearts came from donors with higher Tn-T (6.01+/-0.81 ng/mL) developed episodes of high-grade rejection (3A) within 38.5+/-2.1 days after transplantation. Eight patients who received hearts from donors with intermediate levels of Tn-T (3.57+/-0.55 ng/mL) showed mild rejection (grade 1). All recipients had qualitatively normal left ventricular systolic function by serial echocardiography. The mean donor ischemic time was 169+/-47 minutes. CONCLUSIONS The quality of the donor heart is an important prognostic factor in heart transplantation. It may be possible to identify severely damaged donor organs before transplantation and avoid their use or to develop more aggressive strategies for reducing recurrent acute rejection episodes in high-risk patients.

Abstract
BACKGROUND Modified ultrafiltration (MUF) after cardiopulmonary bypass (CPB) in children decreases body water, removes inflammatory mediators, improves hemodynamics, and decreases transfusion requirements. The optimal target population for MUF needs to be defined. This prospective, randomized study attempted to identify the best candidates for MUF during operations for congenital heart disease. METHODS Informed consent was obtained from 100 consecutive patients with complex congenital heart disease undergoing operations with CPB. They were randomized into a control group (n = 50) of conventional ultrafiltration during bypass and an experimental group using dilutional ultrafiltration during bypass and venovenous modified ultrafiltration after bypass (MUF group, n = 50). Postoperative arterial oxygenation, duration of ventilatory support, transfusion requirements, hematocrit, chest tube output, and time to chest tube removal were compared between the groups stratified by age and weight, CPB technique, existence of preoperative pulmonary hypertension, and diagnosis. RESULTS There were no MUF-related complications. In patients with preoperative pulmonary hypertension, MUF significantly improved postoperative oxygenation (445 +/- 129 mm Hg versus control: 307 +/- 113 mm Hg, p = 0.002), shortened ventilatory support (42.9 +/- 29.5 hours versus control: 162.4 +/- 131.2 hours, p = 0.0005), decreased blood transfusion (red blood cells: 16.2 +/- 18.2 mL/kg versus control: 41.4 +/- 27.8 mL/kg, p = 0.01; coagulation factors: 5.3. +/- 6.9 mL/kg versus control: 32.3 +/- 15.5 mL/kg, p = 0.01), and led to earlier chest tube removal. In neonates (< or =30 days), MUF significantly reduced transfusion of coagulation factors (5.4 +/- 5.0 mL/kg versus control: 39.9 +/- 25.8 mL/kg, p = 0.007), and duration of ventilatory support (59.3 +/- 36.2 hours versus 242.1 +/- 143.1 hours, p = 0.0009). In patients with prolonged CPB (>120 minutes), MUF significantly reduced the duration of ventilatory support (44.7 +/- 37.0 hours versus 128.7 +/- 133.4 hours, p = 0.002). No significant differences were observed between MUF and control patients for any parameter in the presence of ventricular septal defect without pulmonary hypertension, tetralogy of Fallot, or aortic stenosis. CONCLUSIONS Modified ultrafiltration after CPB is safe and decreases the need for homologous blood transfusion, the duration of ventilatory support, and chest tube placement in selected patients with complex congenital heart disease. The optimal use of MUF includes patients with preoperative pulmonary hypertension, neonates, and patients who require prolonged CPB.

Abstract
BACKGROUND Adrenomedullin is a newly identified peptide with profound hypotensive effects. We investigated perioperative adrenomedullin levels among patients with congenital heart disease with and without pulmonary hypertension. METHODS Levels of plasma adrenomedullin, endothelin-1, and nitric oxide metabolites were measured in three groups: (1) low pulmonary flow (n=11); (2) high flow/low pulmonary arterial pressure (less than 60% systemic pressure) (n=9); and (3) high flow/high pressure (n=10). Samples were obtained preoperatively, on and off pump, and 3, 6, and 12 hours after bypass. RESULTS Adrenomedullin levels were highest in the low pulmonary flow group (189.7+/-15 pg/mL low flow versus 103.1+/-9.5 pg/mL high flow/low pulmonary and 139+/-17.5 pg/mL high flow/high pressure at 12 hours; p < or = 0.05). The arterial pressure/systemic pressure remained significantly lower in the high flow/low pulmonary pressure compared with the high flow/high pressure group (0.37+/-0.08 versus 0.62+/-0.11; p < 0.005). Perioperative endothelin-1 and nitric oxide levels remained low in the low pulmonary flow group but increased progressively in both high flow groups. CONCLUSIONS Circulating plasma adrenomedullin appears to affect baseline vascular tone in patients with intact endothelial function. It may interact with nitric oxide and endothelin-1 to help regulate blood pressure perioperatively in patients with congenital heart disease.

Abstract
OBJECTIVE A prospective randomized study was performed to test whether removal of endothelin-1, by ultrafiltration techniques, will reduce pulmonary hypertension after operations for congenital heart disease. METHODS Twenty-four patients with pulmonary hypertension (systolic pulmonary/systemic arterial pressure ratio > 60%) undergoing cardiac operations were randomized into a control group (n = 12) having conventional ultrafiltration and an experimental group (n = 12) undergoing dilutional ultrafiltration during and modified ultrafiltration after cardiopulmonary bypass. Plasma endothelin-1, nitric oxide metabolites, and cyclic guanosine monophosphate were assayed before bypass, 10 minutes into bypass, after bypass, and 0, 3, 6, and 12 hours after the operation in both groups, as well as in the ultrafiltrates and after modified ultrafiltration in the experimental group. Both groups received alpha-blockers (chlorpromazine and/or prazosin) postoperatively using the same guidelines. RESULTS The ultrafiltrates contained significant amounts of endothelin-1 (1.81 +/- 0.86 pg/ml, dilutional, and 6.44 +/- 1.82 pg/ml, modified ultrafiltrate). Endothelin-1 and the pulmonary/systemic pressure ratio were significantly lower in experimental compared with control patients. Nitric oxide metabolites and cyclic guanosine monophosphate increased similarly in both groups for 12 hours after the operation (p = not significant). Three of 12 control patients (25%) but no experimental patients had pulmonary hypertensive crises (p = 0.07). The experimental patients required significantly less ventilatory support (67 +/- 47 hours vs 178 +/- 139 hours for control patients, p = 0.048). CONCLUSIONS Dilutional and modified ultrafiltration reduce endothelin-1 and the pulmonary/systemic pressure ratio postoperatively and may become an important adjunct for preventing pulmonary hypertension after operations for congenital heart disease in high-risk patients.
