Prevalence of sustained hypertension and obesity among urban and rural adolescents: a school-based, cross-sectional study in North India.

OBJECTIVE: Recent data on sustained hypertension and obesity among school-going children and adolescents in India are limited. This study evaluates the prevalence of sustained hypertension and obesity and their risk factors among urban and rural adolescents in northern India. SETTING: A school-based, cross-sectional survey was conducted in the urban and rural areas of Ludhiana, Punjab, India using standardised measurement tools. PARTICIPANTS: A total of 1959 participants aged 11-17 years (urban: 849; rural: 1110) were included in this school-based survey. PRIMARY AND SECONDARY OUTCOME MEASURES: To measure sustained hypertension among school children, two distinct blood pressure (BP) measurements were recorded at an interval of 1 week. High BP was defined and classified into three groups as recommended by international guidelines: (1) normal BP: 95th percentile. The Indian Academy of Pediatrics classification was used to define underweight, normal, overweight and obesity as per the body mass index (BMI) for specific age groups. RESULTS: The prevalence of sustained hypertension among rural and urban areas was 5.7% and 8.4%, respectively. The prevalence of obesity in rural and urban school children was 2.7% and 11.0%, respectively. The adjusted multiple regression model found that urban area (relative risk ratio (RRR): 1.7, 95% CI 1.01 to 2.93), hypertension (RRR: 7.4, 95% CI 4.21 to 13.16) and high socioeconomic status (RRR: 38.6, 95% CI 16.54 to 90.22) were significantly associated with an increased risk of obesity. However, self-reported regular physical activity had a protective effect on the risk of obesity among adolescents (RRR: 0.4, 95% CI 0.25 to 0.62). Adolescents who were overweight (RRR: 2.66, 95% CI 1.49 to 4.40) or obese (RRR: 7.21, 95% CI 4.09 to 12.70) and reported added salt intake in their diet (RRR: 4.90, 95% CI 2.83 to 8.48) were at higher risk of hypertension. CONCLUSION: High prevalence of sustained hypertension and obesity was found among urban school children and adolescents in a northern state in India. Hypertension among adolescents was positively associated with overweight and obesity (high BMI). Prevention and early detection of childhood obesity and high BP should be strengthened to prevent the risk of cardiovascular diseases in adults

Hepatic vascular injury: Clinical profile, endovascular management and outcomes

Background: Endovascular management using angiographic embolization (AE) has been widely used with success as non operative management (NOM) in blunt hepatic trauma. We, in a tertiary care hospital in North of India, assess our use of endovascular management in patients of blunt and post operative trauma with active hepatic vascular bleeding and unstable hemodynamics in controlling bleeding. Methods: A retrospective review of inpatients from January 2006 to July 2012 requiring transarterial embolization/stenting for active hepatic vascular bleeding was done. All patients had evidence of ongoing hemorrhage as proved by clinical, laboratory and radiological findings in emergency settings. Angiographic intervention in an interventional suite with ongoing resuscitation was performed following which patients were monitored for morbidity and mortality benefits on intermediate follow up. Results: 10 adults and 3 children underwent AE with polyvinyl alcohol particle (PVA)/soft metal coil whereas 1 adult underwent revascularization with a covered stent for arterial bleeding. The mean age of case series was 36.18 ± 20.90 years with a mean liver injury computed tomography (CT) grade of 3.8 ± 0.83 in blunt trauma patients. The mean length of hospital stay was 9.62 ± 7.83 days and the mean follow up period of the group was 25.25 ± 21.02 months. All patients showed significant clinical improvement with prompt endovascular management resulting in no procedure related mortality. Conclusion: Prompt endovascular management is the modality of choice in comparison to NOM without AE in both pediatric and adult patients with hemodynamically compromised inaccessible intra hepatic vascular trauma

Case report of isolated congenital absence of right pulmonary artery with collaterals from coronary circulation

Isolated unilateral absence of a proximal pulmonary main artery is a rare congenital lesion which is often associated with other cardiovascular abnormalities and a diverse clinical presentation. It is usually diagnosed in childhood. Patients who survive into adulthood is uncommon. We report a case of 46 year old hypertensive and obese female who presented with progressive dyspnea. She had features of pulmonary hypertension. The diagnosis was confirmed by CT pulmonary angiography which showed absence of right pulmonary artery and conventional pulmonary angiography which showed ipsilateral lung receiving collaterals from Right coronary artery and its branches. The purpose of this report is to highlight the fact that UAPA, although a rare entity, should be kept in mind in patients with unexplained PAH and prolonged respiratory symptoms unresponsive to routine treatment modalities

Impact of catheter fragmentation followed by local intrapulmonary thrombolysis in acute high risk pulmonary embolism as primary therapy

Background: Pulmonary embolism (PE) with more than 50% compromise of pulmonary circulation results significant right ventricular (RV) afterload leading to progressive RV failure, systemic hypotension and shock. Prompt restoration of thrombolysis, surgical embolectomy, or percutaneous mechanical thrombectomy (PMT) prevents progressive hemodynamic decline. We report our single center experience in high risk PE patients treated with standard pigtail catheter mechanical fragmentation followed by intrapulmonary thrombolysis as a primary therapy. Methods: 50 consecutive patients with diagnosis of high risk PE defined as having shock index >1 with angiographic evidence of >50% pulmonary arterial occlusion are included in the present study. All patients underwent emergent cardiac catheterization. After ensuring flow across pulmonary artery with mechanical breakdown of embolus by rotating 5F pigtail catheter; bolus dose of urokinase (4400 IU/kg) followed by infusion for 24 h was given in the thrombus. Hemodynamic parameters were recorded and follow up pulmonary angiogram was done. Clinical and echo follow up was done for one year. Results: Pigtail rotational mechanical thrombectomy restored antegrade flow in all patients. The mean pulmonary artery pressure, Miller score, Shock index decreased significantly from 41 ± 8 mmHg, 20 ± 5, 1.32 ± 0.3 to 24.52 ± 6.89, 5.35 ± 2.16, 0.79 ± 0.21 respectively (p < 0.0001). In-hospital major complications were seen in 4 patients. There was a statistically significant reduction of PA pressures from 62 ± 11 mmHg to 23±6 mmHg on follow up. Conclusions: Rapid reperfusion of pulmonary arteries with mechanical fragmentation by pigtail catheter followed by intrapulmonary thrombolysis results in excellent immediate and intermediate term outcomes in patients presenting with high risk pulmonary embolism

A cost effective endovascular approach for management of post-catheterization profunda femoris artery pseudoaneurysm using thrombin

Post-catheterization PSA is one of the most commonly encountered vascular complications of cardiac and peripheral angiographic procedures. We report the case of patient who developed deep-seated profunda femoris artery pseudoaneurysm (PSA) following cardiac catheterization. Despite, repeated ultrasound guided compressions the PSA failed to close and instead produced local site pressure ulcers. The secondary infection followed which precluded use of percutaneous thrombin injection. The PSA was finally closed via a total endovascular technique combining intravascular thrombin injection and coil embolization, thus obviating the need for expensive measures like cover stents or invasive surgical repairs

Determinants of in-hospital clinical outcome in patients with sub-massive pulmonary embolism

Introduction: There is limited data regarding in hospital determinants of clinical deterioration and outcome in sub massive pulmonary embolism (PE). We aimed to evaluate these determinants by comparing biomarkers, CT pulmonary angiogram echocardiography, electrocardiography variables. Methods: 57 patients of sub massive PE diagnosed on CT pulmonary angiogram were included. All patients received UFH on admission and were divided into two groups based on their clinical course. Group 1 comprised of patients who remained stable, group 2 of patients who showed signs of clinical deterioration. Results: There were 34(59.6%) patients in group 1 and 23(40.4%) patients in group 2. No significant difference in age, gender, BMI. 59.37% had sub massive PE, 5.26% had mortality and 40.4% had clinical deterioration. Intravenous UFH infusion given to 59.6%, systemic thrombolysis 22.8%, catheter directed mechanical breakdown 14%, surgical embolectomy in 3.5% patients. S1Q3T3, new onset RBBB, T wave inversion > 1.63 mm, Basal RV size > 40 mm, RV: LV ratio > 1.2, Global RV longitudinal strain  39 mmHg profiled high risk group. Serum BNP and CT pulmonary angiogram derived scores didn’t differ significantly although CT findings helped to exclude low risk patients (specificity 88%, sensitivity 95%). Conclusions: Physicians should be aware that patients who have ECG and Echocardiography changes suggestive of right ventricular strain and dysfunction above the cut off values and have documented thrombus in Proximal branches (RPA/LPA) or in distal portion of main pulmonary artery may require aggressive management with systemic/catheter based thrombolysis besides routine anticoagulation with heparin to prevent clinical deterioration.

Unusual case of intraoperative acute cor pulmonale during spine surgery

Perioperative complications of prolonged surgery and prone positioning are well known. Changing the position from prone to supine in an anesthetized patient can result in aspiration and airway obstruction. The drop-in oxygen saturation and hemodynamic changes are warning signs and can cause acute cardiac decompensation leading to diagnostic dilemma. We present a case where the patient had these changes after changing the position after spine surgery in prone position. A quick response from the treating anesthesiologist and active involvement of cardiologist helped in reaching the diagnosis and successful management of aspiration pneumonitis in this patient. We conclude that a quick response in investigations and multimodality approach helps in the management of such perioperative complications

Clinical and echocardiographic diagnosis, follow up and management of right-sided cardiac thrombi

Background: Right-sided cardiac masses are infrequent and have varied clinical presentation. The present study describes the clinical features, echocardiographic findings and management of 19 patients presenting with right-sided cardiac thrombi in a tertiary care center in north India. Methods: This is a retrospective, single center observational study of consecutive patients over the period January 2003–2008 admitted in our emergency intensive care unit (EICU). We identified 38 patients with right-sided cardiac masses admitted to EICU diagnosed by transthoracic echocardiography of which 19 patients had right-sided thrombus. The echocardiographic findings were reviewed by two cardiologists in all patients. Treatment was not standardized and choice of therapy was based on judgment of attending physician. Results: The mean age of patients with cardiac thrombus was 36.6 ± 11.8 years. Right atrial (n = 17) and right ventricle (n = 2) thrombi were associated with deep vein thrombosis (DVT) in 7 (36.8%) and pulmonary embolism in 3 (15%) patients. 13 (68.4%) patients appeared to have in situ mural thrombus. 12 patients were managed with oral anticoagulants, 3 patients underwent surgery and 4 patients were thrombolysed. All the survivors had a mean follow-up of 40 ± 6 months (range – 18–50 months). Conclusions: Prompt echocardiographic examination in an appropriate clinical setting facilitates faster diagnosis and management of patients with right-sided cardiac thrombi. High incidence of in situ mural thrombus and varied comorbidities predisposing to right-sided cardiac thrombi besides DVT and pulmonary embolism need to be recognized. Oral anticoagulation and thrombolysis appear to be the mainstay of treatment with surgery limited for selected patients
