Evaluation of Change in Dento-Skeletal Vertical Dimensions using Two Retraction Methods: A Comparative Study

Introduction: The goal of Orthodontic treatment is toimprove the patient’s life through enhancement of Dentofacialfunctions and esthetics. Paradigms have started to shift inOrthodontic world since the introduction of mini-implantsin the anchorage armamentarium. So the present study wasundertaken to analyse and compare the amount of Intrusionin maxillary anterior teeth segment using one and twominiscrews, while paying an utmost attention to patientscomfort and esthetics during the treatment.Material and Methods: The sample consisted of 20 subjectswith deep overbite and complete root formation with increasedincisor show. Lateral cephlogram and P.A Cephalogram wererecorded before placement of implant. Sample was furtherdivided in to two groups, Group I (Implant group one implantis placed between maxillary central incisors and two implantsplaced between second premolar and first molar) and GroupII (Implant Group with Power arms, one implant is placedbetween maxillary central incisor and power arms fabricatedon first molar bilaterally). Clinical evaluation of intrusion wasrecorded on every six weeks.Results: The mean intrusion achieved is 0.28mm per 6weeks interval of time in both groups suggesting there is nodifference in amount of intrusion achieved in both groups withp value of 0.697 which is statistically non-significant. Changein Frankfort mandibular plane angle was observed with GroupI and Group II.Conclusion: On the base of study it was concluded thatimplant and power arm is better choice for intrusion inmaxillary anterior segment for correction of deep overbite andcorrection of gummy smile with minimal effect on posteriorsegment

Study of characteristic of pericardial effusion and to analyze pericardial fluid in various etiologies

Background: Pericardial effusion in clinical practice is commonly under diagnosed or missed especially minimal to moderate effusion. Aim and objectives: To study the clinical and etiological profile of pericardial effusion and to recognize radiological, electrocardiographic and echocardiographic features that are characteristic of pericardial effusion and to analyze pericardial fluid in various etiologies. Materials and methods: It was prospective study in patients presenting with pericardial effusion in department of Medicine and Cardiology. Total of 30 patients who presented with pericardial effusion based on clinical criteria and confirmed by echocardiography were included in the study. Results: The causes of pericardial effusion in this study were Tuberculosis (33.33%), Uremia (20%), Viral /Idiopathic (16.67%), Bacterial (10%), Malignancy (10%), Hypothyroidism (3.33%), and post MI with ischemic cardiomyopathy (3.33%), SLE (3.33%). 3 cases (10%) were HIV positive among viral causes,1 patient had tuberculous pericarditis. ECG findings of low voltage complexes were present in 90% of patients and electrical alternans was seen mainly in tamponade cases. Chest X-ray finding of cardiomegaly was present in 90% patients with pleural effusion in 13.3% patients. ADA levels elevated in all 10 patients of tuberculous effusion with 100% sensitivity and among them smear for AFB was positive in 3 patients. Increased levels of ADA>60U/L was associated with increased incidence of effusive constrictive pericarditis in TB effusion. Pericardial fluid IFN-ᵞ increased greater than 200 pg/L, tuberculous etiology showed 100% sensitivity and specificity. In all 10 patients of M Manjusha, B. Manoj Kumar, N. Venkat Rajaiah, P. Narayana. Study of characteristic of pericardial effusion and to analyze pericardial fluid in various etiologies. IAIM, 2017; 4(10): 221-229. Page 222 2Dimensional echocardiographic findings of right atrial, right ventricular collapse and left atrial collapse was seen predominantly in tamponade cases. Pericardiocentesis showed hemorrhagic effusion in malignancy and uremia, serous and serofibrinous in tuberculosis and purulent in pyogenic effusion. In 3 cases of pyogenic effusion, culture revealed Staphylococcus aureus in 2 patients and Klebsiella pneumonia in 1 patient. Among 3 cases of HIV, one patient had ADA >40 and smear for AFB positive suggesting tuberculous etiology and other 2 cases were directly due to HIV. In HIV with tubercular effusion the patient presented with cardiac tamponade. Conclusions: ADA>40U/L is diagnostic of tuberculous effusion which showed 100% sensitivity and specificity. Increase of ADA>60 U/L is associated with effusive constrictive pericarditis which has poor prognosis. IFN-ᵞ is increased >200pg/l in all patients of tuberculous etiology showing 100% sensitivity and specificity
