Chondromyxoid Fibroma of Clavicle Presenting as Radiological Disappearance of Bone

Case?Presentation Chondromyxoid fibroma (CMF) is a relatively rare bone tumor of cartilaginous origin and it comprises less than 1% of all primary bony tumors. Clavicle is an unusual site of involvement for any bone tumor and may produce diagnostic dilemma. Approximately only 1% of all primary bone tumors may involve the clavicle. The literature on clinical features and outcome of CMF clavicle remains sparse. Conclusion?We present an unusual case of CMF clavicle in which the medial aspect of the clavicle gradually disappeared on radiographs. CMF should be included in the differential diagnoses of disappearing bone disease.

Association of Dietary and Physical Activity Patterns and Hypertension in Western Rajasthan, 2022

Introduction: Hypertension (HTN) is a modifiable risk factor for coronary artery disease, heart failure, cerebrovascular disease and chronic renal failure. HTN affects about 1 billion people globally; by 2025, up to 1.58 billion adults worldwide are likely to suffer from complications of HTN. This study was done to know the diet and physical activity patterns and HTN among the population of three districts of Western Rajasthan. Objectives: To study the dietary and physical activity patterns among the population of Western Rajasthan. and to compare key findings among three districts Pali, Jodhpur and Barmer so that lifestyle changes can be recommended. Methods: A case-control study was done among attendees of NCD clinics of tertiary-level centers in Pali, Barmer and Jodhpur. Hospital Controls were matched to age (± 5 years) and gender Considering the prevalence of HTN to be 20%*, the proportion of exposure in the general population as 0.2, odds ratio to be 2.2, power =80%, alpha=5% sample size is estimated to be 102 cases & 102 controls (from each district). Results: Overall being married (OR= 3.3), having diabetes Cardiac disease (OR= 2.6), excessive salt consumption (OR= 2.7), moderate physical exercise less than 30 minutes (OR=1.9), using oil other than vegetable oil(OR=1.8) , Age >?60 years (OR =1.4) were the key risk factors. It was found that high BMI (BMI>27), consumption of non-vegetable oils (12.7%) was highest in Jodhpur, lack of moderate exercise for at least 30 minutes (81%), lack of sports activity (92%) was highest in Pali, least number of days/week of fruits and vegetables consumption (~1.64 days) was seen in Barmer. Conclusions: Change in quantity of salt consumption and incorporation of moderate physical exercise for >30 minutes was most followed in control of HTN among the attendees of NCD Clinics from the multiple advise given.

Patient profile based management approach for Optimal Treatment of Angina: a consensus from India cases

Chronic stable angina (CSA) is an incapacitating disorder. The pain can hinder the routine chores of an individual and significantly impact one’s quality of life (QoL). However, the good news is that this can be treated and the QoL can be improved. The key to apt management lies in the accurate early diagnosis of this condition, followed by a detailed evaluation and accordingly planned management, which should be regularly revised and be backed by an adequate follow-up. OPTA-OPtimal Treatment for chronic stable Angina-is an educational initiative to assist the clinicians in India with screening and diagnostic tools, strengthened by updated guideline-directed management to ensure satisfactory patient outcomes. OPTA aims to improve clinical outcomes by providing optimized pharmacotherapy for patients with stable angina. This expert consensus document intends to provide information for better understanding of the condition by clinicians and to ensure an early, accurate diagnosis, followed by optimal management of angina. For better clinical and practical understanding of Indian clinical scenario, the most commonly encountered patient profiles are briefly described here. These inputs and an extensive literature review were blended to develop the recommendations for clinicians across the country. An attempt is made to include clinical recommendations that meet the needs of the majority of patients in most circumstances in the Indian scenario. However, the ultimate judgment regarding individual case management should be based on clinician’s discretion. This expert consensus document is not a substitute for textbooks and/or a clinical judgment.

Ewing's Sarcoma of the Rhinomaxillary Complex: A case Report with Review of Literature.

Ewing's Sarcoma of bone (ESB) is a rare primary malignant tumor of bone, belonging to Ewing's Sarcoma Family of Tumors (EFT) and are neuro-ectodermal in origin. These tumors are characterized histopathologically as small round blue cell tumors (SRBCT) containing cytoplasmic glycogen, cytogenetically by a (t:11;22) or (q:24;12) translocation and molecularly by the presence of EWS and FLI1 fusion transcripts. ESB is primarily a pediatric tumor, uncommon in the Asian population, affecting the axial skeleton and rarely the jaw bones. ESB poses a diagnostic challenge as it shares many features with other malignant tumors whose managements are substantially different. We present the clinical, radiographic histopathological and immuno histochemical features of ESB involving the left rhinomaxillary complex in a young Indian male. We also discuss the differential diagnosis and current treatment modalities in management of ESB.

Clinical correlation of multiple biomarkers for risk assessment in patients with acute coronary syndrome.

OBJECTIVE: Biochemical markers are useful for the prediction of future cardiovascular events in patients with non-ST-segment elevation acute coronary syndrome (ACS). The independent as well as the combined prognostic value of elevated troponin-T, high-sensitivity C-reactive protein (hs-CRP), and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) on the Thrombolysis In Myocardial Infarction (TIMI) risk score and on the short-term prognosis were evaluated in a cohort of ACS patients. METHODS AND RESULTS: In an unselected, heterogeneous group of 80 patients with ACS (i.e., unstable angina [USA] or non-ST-elevation myocardial infarction [NSTEMI]), the levels of troponin-T, hs-CRP, and NT-pro-BNP were analyzed. The correlation between elevation of different biomarkers with TIMI risk score and their impact on 30-day major adverse cardiac events was sought. The levels of hs-CRP were significantly higher in patients who had angina as their predominant complaint (3.67 mg/dl vs. 1.67 mg/dl: p < 0.01), while levels of NT-pro-BNP was higher in those patients who had any element of heart failure at presentation (2616.39 pg/ml vs. 1068.3 pg/ml; p < 0.01). Troponin-T was highest in patients who had an element of both heart failure and angina at presentation (p < 0.01). The TIMI risk score expectedly had a positive and strong correlation with elevated troponin-T, but had no correlation with elevation of hs-CRP and NT-pro-BNP in isolation. However, when any two biomarkers were elevated, the patients were in the intermediate risk group as per TIMI risk score irrespective of troponin-T-elevation. When all the three biomarkers were elevated, the risk equaled the high-risk category of TIMI risk score. Elevated hs-CRP (3.40 mg/dl vs. 1.38 mg/dl; p < 0.001) and troponin-T (2.37 ng/ml vs. 1.23 ng/ml; p < 0.001) at baseline correlated independently with the occurrence of re-ischemia, while elevated NT-pro-BNP alone correlated significantly with the development of heart failure within 30 days of follow-up (4247.76 pg/ml vs. 1210.86 pg/ml; p < 0.01). The highest risk of death from any cardiovascular cause within 30 days of follow-up was significantly higher when all the three biomarkers were elevated. CONCLUSION: The use of NT-pro-BNP, hs-CRP, and troponin-T in combination appears to add critical prognostic insight to the assessment of patients with ACS.

"Poor man's risk factor": correlation between high sensitivity C-reactive protein and socio-economic class in patients of acute coronary syndrome.

OBJECTIVE: Inflammation has been proposed as one of the factors responsible for the development of coronary artery disease (CAD) and high sensitivity C-reactive protein (hs CRP) at present is the strongest marker of inflammation. We did a study to assess the correlation of hs-CRP with socio-economic status (SES) in patients of CAD presenting as acute coronary syndrome (ACS). METHODS: Baseline hs-CRP of 490 patients of ACS was estimated by turbidimetric immunoassay. Patients were stratified by levels of hs-CRP into low (<1 mg/L); intermediate (1-3 mg/L) or high (>3 mg/L) groups and in tertiles of 0-0.39 mg/L, 0.4-1.1 mg/L and >1.1 mg/L, respectively. Classification of patient into upper (21.4%), middle (45.37 percent) and lower (33.3%) SES was based on Kuppuswami Index which includes education, income and profession. Presence or absence of traditional risk factors for CAD diabetes, hypertension, dyslipidemia and smoking was recorded in each patient. RESULTS: Mean levels of hs-CRP in lower, middle and upper SES were 2.3 +/- 2.1 mg/L, 0.8 +/- 1.7 mg/L and 1.2 +/- 1.5 mg/L, respectively. hs-CRP levels were significantly higher in low SES compared with both upper SES (p = 0.033) and middle SES (p = 0.001). Prevalence of more than one traditional CAD risk factors was seen in 13.5%, 37.5% and 67.67 percent; in patient of lower, middle and upper SES. It was observed that multiple risk factors had a linear correlation with increasing SES. Of the four traditional risk factors of CAD, smoking was the only factor which was significantly higher in lower SES (73%) as compared to middle (51.67 percent;) and upper (39.4%) SES. We found that 62.3%, 20.8% and 26.5% patients of low, middle and upper SES had hs-CRP values in the highest tertile. Median value of the Framingham risk score in low, middle and upper SES as 11, 14 and 18, respectively. We observed that at each category of Framingham risk, low SES had higher hs-CRP. CONCLUSION: We conclude from our study that patient of lower SES have significantly higher levels of hs-CRP despite the fact that they have lesser traditional risk factors and lower Framingham risk. These findings add credit to our belief that inflammation may be an important link in the pathophysiology of atherosclerosis and its complications especially in patients of low SES who do not have traditional risk factors.

Ruptured left sinus of valsalva aneurysm to right atrium.

A 6-year-old child presented with left sinus of Valsalva aneurysm opening in right atrium. Origin of sinus of Valsalva from left aortic sinus and its opening into right atrium is extremely rare. The anomaly was corrected surgically by patch closure at the aortic end. Follow-up echocardiography did not reveal any residual shunt in right atrium.

Gangliogliomas: A report of five cases.

Gangliogliomas are rare tumors of the Central Nervous System. Five gangliogliomas were diagnosed out of 1560 brain tumours surgically resected out in a period of 5 years accounting for 0. 32%. We have tried to discuss in detail the pathological features of these tumours and have mentioned the clinical and radiological features associated with them. All the slides, tissue blocks and pathology reports of the surgical specimens of gangliglioma were reviewed and the clinical and radiological data reviewed. The ages of the patients ranged from 7-65 years with 4 males and 1 female. The tumors were located in the lateral ventricle (a rare site), temporal, parietal and the frontal lobes with duration of seizures varying from 1-9 years. The tumors were diagnosed by the presence of a dual population of neoplastic ganglionic and glial components. The glial components consisted of pilocytic astrocytes (l case), fibrillary astrocytes (2 cases), oligodendrocytes (1 case) and anaplastic astrocytes and oligodendrocytes (1 case). There was one-grade I GG, three-Grade II GGs and one-grade III GG. Astrocytes were the commonest glial component of GGs, either pilocytic or fibrillary. Oligodendrocytes as the glial component of GGs was seen in 2 cases one of which was anaplastic and this is a rare finding.

Short-term (48 hours) versus long-term (7 days) antibiotic prophylaxis for permanent pacemaker implantation.

BACKGROUND: Infection following permanent pacemaker implantation is a dreaded complication. Antibiotic prophylaxis for 1-10 days at the time of implant has been used in the past but there is no consensus regarding its duration. We carried out a prospective, randomized study of two durations of antibiotic prophylaxis to determine which one was more effective. METHODS AND RESULTS: One hundred and seventy-eight patients undergoing permanent pacemaker implantation for the first time were randomized to receive short duration (group A, n = 8 8) or longer duration (group B, n = 90) antibiotic prophylaxis for 2 days and 7 days, respectively. Patients in both groups received cloxacillin 2 g 2 hours prior to the procedure followed by ampicillin and cloxacillin (50 mg/kg/day in 4 divided doses) and gentamicin (3 mg/kg/day in 2 divided doses) for the respective duration. Patients were followed up for 1-17.3 months (9.3 +/- 1.8 months) in group A and 1-16.5 months (8.9 +/- 2 months) in group B. One patient in group B had an infection at the pacemaker site and two patients in each group had to undergo reimplantation due to pus in the pocket. There was no significant difference in the primary end-point in both groups. CONCLUSIONS: A short course (48 hours) of antibiotic prophylaxis following permanent pacemaker implantation is as effective as a longer course (7 days).

Pulmonary blastoma.

A three-and-half-year-old boy presented with recurrent chest infections, fever and weight loss of three month duration not responding to antibiotics. The chest X-ray and CT scan revealed a large well-circumscribed mass in right upper thorax with collapse of right upper lobe. A preoperative diagnosis could not be made even after fine needle aspiration cytology. Thoracotomy and right upper lobectomy was done and the biopsy report was an inflammatory pseudotumor. The child remained well for three months after which his symptoms and the mass recurred. The histopathology slides were reviewed and revealed a biphasic malignant tumor suggestive of Pulmonary Blastoma (PB). Patient received four cycles of chemotherapy followed by re-exploration. The recurrent tumour could only be excised partly and the child succumbed to persistent shock postoperatively. The final histopathological diagnosis was confirmed as PB. Primary pulmonary neoplasms in children are rare and of these PB which is even rarer, constitutes less than 15%. The report highlights that the lack of familiarity with this entity still causes error in the diagnosis of PB.

Lipoprotein (a) and lipid levels in young patients with myocardial infarction and their first-degree relatives.

BACKGROUND: Studies among emigrant Indians have stressed the role of a powerful genetic factor, lipoprotein (a), in the causation of premature coronary artery disease. This study was carried out to assess lipoprotein (a) and lipid levels in 50 consecutive young north Indian patients (age less than 45 years, mean age 39+/-3.7 years) with myocardial infarction, their first-degree relatives (n=125, mean age 36+/-16 years), and age- and sex-matched controls (n=50, mean age 34+/-6.9 years). METHODS AND RESULTS: Blood samples for lipid estimation were taken within 24 hours of myocardial infarction and after overnight fasting for twelve hours. Lipoprotein (a) levels were estimated by the ELISA technique using preformed antibodies while lipid levels were estimated by kits using the colorimetric method. All were male patients. The mean lipoprotein (a) level was 22.28+5.4 mg/dl in patients, 13.88+5.19 mg/dl in their first-degree relatives and 9.28+22.59 mg/dl in controls. In addition, it was significantly higher in young patients with myocardial infarction and their relatives as compared to controls (p<0.001 for patients v. controls and p<0.05 for relatives v. controls). There was no significant difference in the levels of total cholesterol and low-density lipoprotein cholesterol among the three groups. High-density lipoprotein cholesterol was significantly lower in young patients with myocardial infarction (30.16+/-9.45 mg/dl) and their first-degree relatives (33.28+/-8.45 mg/dl) as compared to controls (46.8+/-8.04 mg/dl) (p<0.001 for patients v. controls and p<0.01 for relatives v. controls). Triglyceride levels were significantly higher in patients as compared to controls (202+/-76 mg/dl v. 149 + 82.99 mg/dl, p<0.05). Smoking was more prevalent in young patients with myocardial infarction as compared to controls (44% v. 36%, p<0.05). CONCLUSIONS: Smoking, high lipoprotein (a) and triglyceride levels and low high-density lipoprotein levels may be important risk factors for coronary artery disease in the younger population; also, there is familial clustering of high lipoprotein (a) levels in first-degree relatives of young patients with myocardial infarction.

Left ventricular pacing through coronary sinus tributaries: initial experience.

BACKGROUND: Left ventricular pacing is increasingly being used as a part of biventricular pacing in congestive heart failure but data on safety, feasibility, reliability and lead maturation are sparse. METHODS AND RESULTS: Seventeen patients (13 males and 4 females) with persistent symptomatic degenerative complete heart block underwent temporary left ventricular pacing by a left subclavian puncture through the coronary sinus to its tributaries using a unipolar permanent pacing lead connected to an external pulse generator. The left ventricular pacing was done for two weeks. Permanent right ventricular apical pacing was also done at the same time through a right cephalic vein cut-down or subclavian puncture and the pacing rate was kept below that of the initial left ventricular pacing rate. Pacing parameters of the left and right ventricles were assessed at the time of implantation and at two weeks. Out of 17 patients, left ventricular pacing was successful in 11 (67.7%) patients. The time taken for the total procedure was 56+/-18.1 min. Lead displacement was noted in one patient without loss of pacing. At the time of implant and after two weeks, left ventricular pacing threshold, impedance, R wave height and slew rate were not different as compared to right ventricular pacing. Holter recording for 24 hours revealed regular left ventricular pacing at the end of two weeks in all patients. CONCLUSIONS: The present study shows that left ventricular pacing through coronary sinus tributaries is feasible and reliable. Acute and subacute maturation of left ventricular pacing are similar to right ventricular apical pacing.

Megadose heparin and streptokinase produce similar TIMI 3 flow at discharge in patients of acute myocardial infarction presenting between 7-12 hours.

The present study was undertaken to assess the impact of megadose heparin bolus on angiographic patency of infarct-related artery in patients of acute myocardial infarction presenting between 7-12 hours and to compare it with streptokinase. Forty-seven patients (27 males, mean age 58.1 +/- 9.6 years) of acute myocardial infarction between 7-12 hours of onset of chest pain were randomised to receive either megadose heparin bolus (300 IU/kg body weight, group 1, n = 24; or streptokinase 1.5 million units over one hour, group 2, n = 23). Parameters noted were: relief of pain at 90 minutes, 50 percent or more resolution of ST segment at 90 minutes, TIMI grade flow and left ventricular ejection fraction at discharge. Mean age (59.0 +/- 12.9 years in group 1; 57.2 +/- 8.1 years in group 2), mean time to drug (7.5 +/- 1.3 hours in group 1; 7.8 +/- 1.6 hours in group 2), site of anterior wall infarction (12 in group 1, 10 in group 2), relief of pain at 90 minutes (15 in group 1, 14 in group 2) and more than 50 percent resolution of ST segment elevation at 90 minutes (12 patients in each group) were similar. On coronary angiography performed in 42 patients (21 in each group) at a mean interval of 7.2 +/- 1.3 days after acute myocardial infarction, TIMI grade 3 flow was seen in 7 (33.3%) patients in each group and TIMI grade 2/3 flow was also similar in both the groups (p = NS). No major bleed occurred in either group. We conclude that heparin given as a megadose bolus produces similar TIMI 3 flow in infarct-related artery as compared to streptokinase in acute myocardial infarction patients presenting between 7-12 hours.

Accelerated infusion of streptokinase in acute myocardial infarction results in better TIMI flow grade in infarct-related artery.

Bolus followed by rapid infusion of tissue plasminogen activator results in higher grade of TIMI flow in infarct-related artery as compared to slow infusion. In the present study, an accelerated regimen of streptokinase given over 15 minutes was compared with conventional infusion over one hour in 47 patients presenting within 12 hours of acute myocardial infarction. Forty-seven patients (44 males, 3 females; mean age 54.0 +/- 1.1 years) were randomly allocated to receive 1.5 million units of streptokinase either over 15 minutes (group 1, n = 24) or over one hour (group 2, n = 23) at a mean interval of 5.4 +/- 3.6 hours after onset of symptoms. All the patients received aspirin and intravenous heparin (1000 U/hr) for 96 hours after thrombolysis. Coronary angiography was performed in 43 patients (22 in group 1, 21 in group 2) prior to discharge from the hospital (mean 7 +/- 2.1 days after acute myocardial infarction) and patency of the infarct-related artery and grade of TIMI flow were determined. Infarct-related artery was patent (TIMI 2/3 flow) in 19 (86.4%) patients in group 1 as compared to 12 (57.1%) in group 2 (p < 0.05). TIMI grade 3 flow in the infarct-related artery was present in 13 (59.1%) in group 1 as compared to 7 (33.3%) in group 2 (p = 0.1). There was no significant difference between group 1 and 2 in time of presentation (mean 5.3 +/- 3.9 hrs vs 5.5 +/- 3.2 hrs), time to needle in hospital (25.6 +/- 11.2 min vs 26.3 +/- 6.2 min), site of infarct (anterior myocardial infarction 12 in group 1 vs 11 in group 2), relief of pain at 90 min (13 vs 12), more than 50 percent reduction of ST elevation at 90 minutes (17 vs 12) and left ventricular ejection fraction (48.8 +/- 9.1% vs 49.8 +/- 16.0%), respectively. Streptokinase was well tolerated in both the groups, although hypotension was more common with the accelerated regimen (5 in group 1 vs 3 in group 2; p = NS). Thus, 'accelerated' streptokinase given over 15 minutes in patients presenting within 12 hours of acute myocardial infarction is well tolerated and results in higher grades of TIMI flow in the infarct-related artery as compared to the "conventional" one-hour infusion regimen.
