Prevalence and follow-up of subclinical rheumatic heart disease among asymptomatic school children in a north-western district of India based on the World Heart Federation echocardiographic criteria.

Echocardiography 2021 07 28;38(7):1173-1178. Epub 2021 May 28.

Background: The present study is based on the World Heart Federation (WHF) echocardiographic criteria to assess the prevalence of subclinical rheumatic heart disease (RHD) and elucidate evolution of the disease when the cases were placed on appropriate antibiotic prophylaxis and regular follow-up. The prevalence of subclinical RHD reported by previous active surveillance studies among asymptomatic school children is not comparable to our study because of major differences in screening methods.

Methods: A random inclusion strategy was adopted to recruit urban and rural school children of Bikaner district in the state of Rajasthan, India. The diagnosis of RHD was based on the echocardiographic criteria proposed by the WHF. All studies were reported on-site by a single experienced cardiologist and the digitally preserved studies were reported by a second cardiologist off-site. The final diagnosis was made by consensus. The second echocardiogram was performed for cases diagnosed with RHD after two years from start of study to document early evolution of the disease with ongoing antibiotic prophylaxis.

Results: A high prevalence of subclinical RHD was observed in the study population. Pathological mitral and/or aortic valve regurgitation was the commonest lesion, and a significant proportion of cases improved while on regular antibiotic prophylaxis. No case showed fixity of leaflets/ stenosis.

Conclusion: The prevalence of subclinical RHD is high in the study population, and the disease seems to regress over time in the presence of appropriate antibiotic prophylaxis.

Characteristics and Outcomes of Hospitalized Young Adults with Mild Covid -19.

J Assoc Physicians India 2020 Aug;68(8):62-65

Department of Research, RUHS College of Medical Sciences, Rajasthan.

Background: Stormy course has been reported among hospitalized adults with COVID-19 in high- and middle-income countries. To assess clinical outcomes in consecutively hospitalized patients with mild covid-19 in India we performed a study.

Methods: We developed a case registry of successive patients admitted with suspected covid-19 infection to our hospital (n=501). Covid-19 was diagnosed using reverse transcriptase polymerase chain reaction (RT-PCR). Demographic, clinical, investigations details and outcomes were recorded. Descriptive statistics are presented.

Results: Covid-19 was diagnosed in 234 (46.7%) and data compared with 267 (53.3%) negative controls. Mean age of covid-19 patients was 35.1±16.6y, 59.4% were <40y and 64% men. Symptoms were in less than 10% and comorbidities were in 4-8%. History of BCG vaccination was in 49% cases vs 10% controls. Cases compared to controls had significantly greater white cell (6.96+1.89 vs 6.12+1.69x109 cells/L) and lower lymphocyte count (1.98+0.79 vs 2.32+0.91x109 cells/L). No radiological and electrocardiographic abnormality was observed. All these were isolated or quarantined in the hospital and observed. Covid-19 patients received hydroxychloroquine and azithromycin according to prevalent guidelines. One patient needed oxygen support while hospital course was uncomplicated in the rest. All were discharged alive. Conversion to virus negative status was in 10.2±6.4 days and was significantly lower in age >40y (9.1±5.2) compared to 40-59y (11.3±6.1) and ≥60y (16.4±13.3) (p=0.001).

Conclusions: This hospital-based registry shows that mildly symptomatic or asymptomatic young covid-19 patients have excellent prognosis.

Management of the dental patient on anticoagulant medication: a review.

N Y State Dent J 2014 Jun-Jul;80(4):29-32

Patients taking anticoagulant medication pose a challenge for the clinician. Dentists are often required to manage bleeding as part of routine oral surgery or dental procedures, and altered hemostasis can lead to complications. Nevertheless, use of these medications is generally important for the patient's health and any alteration in the anticoagulant regimen may have untoward sequelae. In addition, several medications can affect the clotting mechanism, potentially compromising hemostasis. This article will review a variety of anticoagulant medications and the medical conditions that necessitate their use.

Comparison of the Reliability of Anatomic Landmarks based on PA Cephalometric Radiographs and 3D CT Scans in Patients with Facial Asymmetry.

Int J Clin Pediatr Dent 2011 Sep-Dec;4(3):213-23. Epub 2011 Apr 15.

Introduction: Conventional cephalometry is an inexpensive and well-established method for evaluating patients with dentofacial deformities. However, patients with major deformities and in particular asymmetric cases are difficult to evaluate by conventional cephalometry. Reliable and accurate evaluation in the orbital and midfacial region in craniofacial syndrome patients is difficult due to inherent geometric magnification, distortion and the superpositioning of the craniofacial structures on cephalograms. Both two- and three-dimensional computed tomography (CT) have been proposed to alleviate some of these difficulties.

Aims And Objectives: The aim of our study is to compare the reliability of anatomic cephalometric points obtained from the two modalities: Conventional posteroanterior cephalograms and 3D CT of patients with facial asymmetry, by comparison of intra- and interobserver variation of points recorded from frontal X-ray to those recorded from 3D CT.

Materials And Methods: The sample included nine patients (5 males and 4 females) with an age range of 14 to 21 years and a mean age of 17.11 years, whose treatment plan called for correction of facial asymmetry. All CT scans were measured twice by two investigators with 2 weeks separation for determination of intraobserver and interobserver variability. Similarly, all measurement points on the frontal cephalograms were traced twice with 2 weeks separation. The tracings were superimposed and the average distance between replicate points readings were used as a measure of intra- and interobserver reliability. Intra-and interobserver variations are calculated for each method and the data were imported directly into the statistical program, SPSS 10.0.1 for windows.

Results: Intraobserver variations of points defined on 3D CT were small compared with frontal cephalograms. The intraobserver variations ranged from 0 (A1, B1) to 0.6 mm with the variations less than 0.5 mm for most of the points. Interobserver variations of points between first and second tracings defined on PA Ceph and 3D CT were less than 1.5 mm for all the points. A direct comparison of frontal cephalometry and 3D CT using intraobserver variation for the first observer showed that 3D CT was more reliable than frontal cephalometry for 11 points. Direct comparison of frontal cephalometry and 3D CT for the second observer showed a similar tendency with 14 points significantly more reliable for 3D CT. Comparison of frontal cephalometry and 3D CT using interobserver variation for the tracings showed that 3D CT was more reliable than frontal cephalometry.

Summary And Conclusion: The study has shown that 3D CT is consistently more accurate and reliable than conventional frontal cephalometry. Unfortunately, the cost of a computerized tomography examination is considerable; this means that, at this stage, its use by surgeons and orthodontists is a last resort.
