Authors: Gupta Varun , Narang Savjot Singh , Gill Chiranjiv Singh , Selhi Pavneet Kaur , Gupta Manvi 
Published: March 2023

Background:
Current severity assessment scores of acute pancreatitis (AP) include multiple variables, the results of which are available only after 48 h of admission. Red cell distribution width (RDW) and total serum calcium (TSC) are simple routine parameters related to inflammatory status and results of which are readily available.

Aim:
The aim of this study was to evaluate RDW and RDW: TSC within 24 h of hospital admission as predictors of outcome (severity and mortality) and intervention (medical/percutaneous drainage/surgical) required by patients of AP.

Materials and Methods:
All the patients diagnosed with AP at a tertiary care hospital were enrolled for the study. Values of RDW and TSC along with data regarding the treatment given were collected. Diagnosis and severity were defined according to the revised Atlanta classification 2012.

Results and Interpretation:
Cutoff value for RDW (area under the receiver operating characteristic curve [AUROC]: 0.997; P = 0.000) to predict the severity of AP was 16.25% (sensitivity - 100% and specificity - 97.1%,) (sensitivity - 100% and specificity - 97.1%, positive predictive value - 92.31%, negative predictive value - 100%, and Youden Index - 0.971), while that of RDW:TSC (AUROC: 1; P = 0.000) was 2.42 (sensitivity - 100%; specificity - 100%, positive predictive value - 100%, negative predictive value - 100%, and Youden Index - 1.00). Similarly, the cutoff value for RDW (AUROC: 0.947; P = 0.000) to predict mortality in AP was 17.20% (sensitivity - 100%; specificity - 87.4%, positive predictive value - 38.89%, negative predictive value - 100%, and Youden Index - 0.874) and that of RDW-to-TSC ratio (AUROC: 0.975; P = 0.000) was 2.9 (sensitivity - 100%; specificity - 96.6%, positive predictive value - 70%, negative predictive value - 100%, and Youden Index - 0.966).

Conclusion:
Our study found that RDW and RDW: TSC were quick, convenient, economic, sensitive, and dependable prognostic predictors of severity and mortality in patients with AP.
Pulmonary Hypertension, an Echo Assessment: Is it Arterial or Venous?
Authors: Sullere Vivek , Sullere Shivang , Khan Idris Ahmed , Goyal Rajendra G. 
Published: March 2023

Introduction:
Pulmonary hypertension (PH) is characterized by pulmonary vascular remodeling, right heart failure, and reduced survival. PH can be PH without left ventricular (LV) dysfunction – pulmonary arterial hypertension (PAH) - (Dana point Class I) and PH with LV dysfunction – pulmonary venous hypertension (PVH) - (Dana point Class II). Whatever the underlying cardiac disease, the presence of PH in patients with heart failure is associated with poor prognosis. Right ventricular dysfunction by ventricular interdependence can cause LV dysfunction.

Objective:
We aim to provide a distinction between PAH and PVH by echocardiography.

Methods:
Retrospective cross-sectional single-center data of 1075 subjects having PH as defined by echocardiography was collected. These were segregated into mild, moderate, and severe categories. The same cohort of PH subjects was also segregated by E/e’ derived pulmonary capillary wedge pressure (PCWP) values. Echocardiographic measurements and effort tolerance in Mets were analyzed. Data for 707 normal subjects were taken from an earlier published study on normative echocardiographic measurements of healthy Indians.

Results:
Our findings show that PAH and PVH can be distinguished using PCWP value >15 mmHg obtained by applying Nagueh’s formulaon E/e’.

Conclusion:
We recommend that PCWP derived from E/e’ should be reported with pulmonary artery systolic pressure measurement to distinguish between PAH and PVH.

Authors: Madhusudanan Midhila , Shenoy Vidya K. , Khan Jalis A. , Mehendale Avinash V. , Bangera Madhu K. 
Published: March 2023

Background:
Flow characteristics of vinyl polysiloxane (VPS) impression materials are important determinants in the selection of impression materials for the fabrication of accurate indirect restorations.

Aims:
The purpose of this study was to determine the flow of three commercially available VPS impression materials at different time intervals using a shark fin device (3M ESPE, Seefeld, Germany).

Study Setting and Design:
This in-vitro study was carried out at the prosthodontics department of a dental institution.

Methods and Material:
The height of the shark fin produced by each impression material determined the rate of flow.

Statistical Analysis:
The data were analysed using one-way analysis of variance (ANOVA) and post-hoc Tukey's test (p-0.05).

Results:
Shark fin height of group A VPS impression material was significantly higher at 30 and 120 seconds compared to group B and group C VPS impression materials. Shark fin height produced by group B VPS impression materials at 60 and 90 seconds was significantly higher than the group C VPS impression material but non-significant compared to group A. At 120 seconds, there was no significant difference in the shark fin heights of all the tested materials.

Conclusion:
All the materials exhibited adequate flow characteristics within clinically acceptable limits.

Published: March 2023

Context:
The proliferation and differentiation of human periodontal ligament stem cells (hPDLSC) into other cell types are also mediated by mechanical stresses; they might offer therapeutic benefits in tissue regeneration and angiogenesis.

Objectives:
The study was planned to assess the proliferation, clonogenic potential, and osteogenic differentiation of human periodontal ligament stem cells (PDLSC) following the application of light and heavy orthodontic forces.

Materials and Methods:
A couple forces of 50 gm (light force) were applied on the 1st premolar on the one side and 250 gm (heavy force) on the contralateral side in the upper arch of patients requiring orthodontic treatment with extraction of all 1st premolars. After 30 days, periodontal tissues were scrapped from extracted teeth for the establishment of PDLSC in vitro. PDLC from the lower premolar teeth where no orthodontic force was applied acted as the control group. Morphology, viability, proliferating rate and population doubling time, clonogenicity, and alkaline phosphatase activity were analysed.

Result:
The osteogenic potential was confirmed by Alizarin red staining and the expression of the osteogenic markers by qRT-PCR. The morphology, growth kinetics, potency, and osteogenic lineage characteristics inferred the application of high force reduced the proliferative ability and osteogenesis of PDLSC, though the difference was not significant.

Conclusion:
The established PDLSCs demonstrated their MSC-like properties based on morphology, growth kinetics, colony forming ability, and AP activity. The culture-expanded PDLSCs showed their differentiation potential into osteocytes. The application of high force reduced the proliferative ability and osteogenesis of PDLSCs, variations were not significant.

Published: March 2023

Background:
Recession is a mucogingival condition affecting teeth causing hypersensitivity. Although many techniques are there for recession coverage, semilunar vestibular incision technique (SVIT) is a novel procedure for management of multiple gingival recession in maxillary teeth.

Aim:
To evaluate the efficacy of root coverage in maxillary teeth with multiple gingival recession using SVIT.

Methodology:
Twenty systemically healthy patients were recruited with Miller's class I and II gingival recessions in maxillary teeth. Parameters such as recession height (RH), recession weight (RW), avascular surface area (ASA), width of keratinized gingiva (WKG), width of attached gingiva (WAG), and clinical attachment level (CAL) were measured at baseline three and six months post-surgery.

Results:
The outcome measures were statistically significant at baseline, three and six months. A reduction of 86% was achieved in terms of RH and RW. Gain in WKG and WAG as achieved at six-month follow-up was 31.5% and 55%, respectively. An 87% decrease in ASA was obtained and reduction in CAL was 82.4%. Between three and six months there was a significant increase in WAG.

Conclusion:
SVIT results in improved measures of attached gingiva on six-month follow-up.

In comparison to multiple file systems, recent advancements in single file retreatment systems had reduced the working time and ease of operation for clinicians.

Aim:
To compare the efficacy of retreatment systems compared with hand instrumentation, by evaluating their removal efficacy, time required for retreatment and assessment of canal transportation.

Methods and Material:
Forty premolars were instrumented using ProTaper Gold gold files. Post instrumentation, scan was taken, obturated using warm vertical compaction technique, and stored in artificial saliva for three months and randomly divided into four groups for retreatment. Hand instrumentation (Hi), Neoniti (Nn), Mtwo R (Mt), WaveOne Gold (Wg). Post retreatment, scan was taken. Teeth were sectioned longitudinally and photographed under the stereomicroscope. Retreatment time was recorded, and canal transportation was calculated.

Statistical Analysis:
The results were analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post hoc test at 95% confidence level.

Results:
The retreatment time was significantly longer in the Hi group. Within the test groups, a significantly longer time has been taken by Wg (p < 0.05) compared to Mt and Nn. There was no difference in the canal transportation between the single file systems at 3 mm, 6 mm and 9 mm from the apex, there was statistically significant higher transportation for the Hi group at 9 mm from the apex (p < 0.05).

Conclusions:
All techniques were effective in removal of filling material with minimal canal transportation. Wg system was shown to increased time compared to Nn and Mt systems. Hi group was slowest with maximum canal transportation at 9 mm from the apex.

Published: March 2023

Abstract
Ratol is a rodenticide (rat killer paste) that contains yellow phosphorus, a dangerous toxin that harms the gastrointestinal, hepatic, cardiovascular, and renal systems both locally and systemically. The liver is one of these that is most frequently injured, and the most terrifying result is acute liver failure with coagulopathy. A 25-year-old male who is a known case of epilepsy and was on medication was brought to the Emergency Department by his mother with an alleged history of consuming approximately 15 g of Ratol paste mixed in water 5 days before presentation to our hospital at around 5 pm at his residence. The patient sustained nausea and vomiting during the following day of consumption and was treated for the same in a nearby hospital. The main element in lowering morbidity and death is the provision of effective and timely supportive care.

Published: March 2023

AbstractIntroduction:Gastro-esophageal reflux disease (GERD) is a condition characterized by the reflux of stomach contents into the esophagus, causing unpleasant symptoms and/or consequences like heartburn and acid regurgitation. GERD in the student stages can hurt their quality of life, college attendance, everyday activities, and overall well-being of the individual.Materials and Methods:This is a cross-sectional study that was conducted among medical students of a tertiary care setting from August 2021 to October 2021 for a three-month duration. A convenient sample of 458 participants from all the years of MBBS was included in this study.Results:A total of 458 medical students were made part of this study of which most of them (58.9%) were females and 41.1% were males. The average age among the study participants was 22 ± 2.3 years (range of 18–27 years). The average BMI of the individuals was 23.48 (range 14.58–32.41), with the majority (54.8%) of them having a normal BMI.Discussion:In our study, we found that the prevalence of GERD in the medical students of a rural Indian tertiary care setting was 24.2%, and was observed that irregular meal timings and consuming coffee and soft drinks are the crucial risk factors for developing GERD in the medical students in comparison to the general population.Conclusion:Medical students should be trained on proper eating habits, maintaining ideal body weight, good sleep hygiene, and avoiding drinking alcohol and smoking to lessen the burden of GERD.

Abstract

Introduction:
Hip fractures in the elderly have represented a major public health concern. Studies have shown that over 90% of the patients having these fractures are people of more than 50 years. These fractures have been classified according to their anatomical location into the neck of femur fracture, intertrochanteric fracture, and subtrochanteric fracture. The neck of femur fractures is associated with high mortality in the elderly compared to young adults. Surgical treatment is an established gold standard, with the option being osteosynthesis and hip replacement. Hemiarthroplasty is one of the gold-standard treatments chosen for the geriatric age group and has yielded universally acceptable results.

Materials and Methods:
The study evaluates the clinical, radiological, and functional outcomes of hip hemiarthroplasty in elderly with fracture neck of the femur Data of patients above 60 years who were operated on for fracture neck of the femur by bipolar hemiarthroplasty from May 2018 till December 2021were retrieved from the Medical Records Department of SCL Municipal General Hospital, affiliated to NHL Municipal medical college. The patients fitting the inclusion criteria were selected for the study. The sample size was calculated to be 43. Data were collected from the inpatient files, and then patients were asked to complete the questionnaire form during the final follow-up. All the patients were evaluated clinically and radiologically during the follow-up, and the functional outcome was assessed using the Harris Hip Score. Thirty-five patients had a domestic fall as the mode of injury. The lateral decubitus position of all patients was used during the operation that was performed using the Southern Moore approach. Forty patients received cemented femoral stems; the remaining three received press-fit ones.

Results:
The average age was calculated to be 71.86 years with the male-to-female ratio of 1: 1.15 with an average follow-up of 12.7 months. Eight patients had acetabular erosion at the end of 1 year. There was no femoral stem malalignment or aseptic loosening at the final follow-up. Nine patients had excellent Harris Hip scores, and five had fair scores. The remaining 29 patients had good Harris hip scores. Bipolar hemiarthroplasty has served us well in the study. Forty-one patients were able to get back to their preinjury functional level. Only one patient reported major pain in the hip at the final follow-up. In this study, there was no incidence of dislocation or revision surgeries.

Conclusion:
The present study modular bipolar hemiarthroplasty provides better pain relief with early mobilization and a good level of return to daily routine activities with minimal complications.

Published: March 2023

Abstract

Background:
Breast Imaging Reporting and Data System (BI-RADS) classification for breast lesions was proposed for uniformity in categorizing breast lesions. While BI-RADS 1, 2 and 4–6 categories are straightforward, BI-RADS 3 is an intermediate category lesion with significantly different meanings and findings for mammography, ultrasound, and magnetic resonance imaging and is diagnostically challenging. Our study aims to determine the frequency and the malignancy rate of BI-RADS category 3 lesions detected on ultrasound breast and digital X-ray mammography by doing follow-ups at 6, 12, and 24 months of imaging.

Materials and Methods:
This ambispective study was conducted in the Department of Radiodiagnosis, Jawaharlal Nehru Medical College and Hospital, Aligarh Muslim University, Aligarh, from October 2020 to October 2022, which included 55 patients referred for digital X-ray and breast ultrasound. All BI-RADS category 3 in the initial sonomammography and digital X-ray mammography were included in the study and were followed up for final diagnosis and outcome either by pathological analysis or follow-up using sonomammography and digital X-ray mammography for a maximum of 24 months.

Results:
Fifty-five patients were categorized into the benign or malignant category from the results of tissue diagnosis or via follow-up. Fifty-four patients (98.18%) showed benign lesions, and one (1.82%) got malignant lesions. In the majority, 31 (56.36%) patients, the mean follow-up time was 6 months, followed by 12 months 10 (18.18%). Follow-up was 24 months in only 1 out of 55 patients (1.82%). The mean value of time to follow-up (months) of study subjects was 6 ± 4.6 with a median (25th–75th percentile) of 6.

Conclusion:
Short-term interval follow-up in BI-RADS category: three patients are enough to detect early breast malignancy, and this will avoid unnecessary tissue diagnosis (invasive procedure) in benign lesions. In our study, the malignancy yield in the follow-up of BI-RADS 3 was 1.82% (<2%).

El objetivo del presente trabajo es la construcción de un modelo credit scoring de probabilidad con la finalidad de minimizar el riesgo de incumplimiento de pago de la cartera de clientes, para lo que se utilizó variables dependientes (cliente “bueno o malo”) y como independientes (características de los clientes) para proporcionar un análisis correcto para determinar si la empresa concede o no un crédito. Se aplicó la metodología descriptiva y enfoques cuantitativos y cualitativos tomando como fuentes primarias los datos de la cartera de clientes de la empresa SEGUMAR S.A. La base de datos consiste de la información de 100 personas solicitantes de un crédito y se incluye en la medición de 7 variables para cada persona. Cada solicitante se clasifica en una de dos categorías posibles, "buen cliente" (70 casos) o "mal cliente" (30 casos). Se desarrolló una regla de credit scoring para determinar si un nuevo solicitante es “Bueno” o “Malo” cliente, basándose en los valores de una o más variables explicativas resultantes del modelo final. Este estudio evaluó las características que tienen los clientes al momento de pedir un crédito y según las características de cada cliente se puede realizar predicciones, clasificarlos como un buen o un mal cliente. En los resultados obtenidos del modelo Logit se puede concluir que las variables seleccionadas que se aplicaron en el modelo arrojaron un 76% de éxito que nos permite clasificar a cada uno de nuestros clientes como un buen cliente o mal cliente en nuestro modelo.
