Spectrum of histopathological changes and its quantification using a scoring system in patients with gastroesophageal reflux disease.

Aim: The aim of this study was to evaluate the role of histopathological and histomorphometric features in oesophageal biopsy of patients presenting with symptoms of Gastroesophageal Reflux Disease (GERD). Material and Methods: Present study included 42 patients and 12 controls. Complete clinical evaluation followed by endoscopic examination of the patients was done and multipleoesophageal biopsies were taken. Biopsies were processed routinely and stained with Hematoxylin and Eosin and examined for any changes related to GERD. Morphometric assessment was done by using Leitz optical micrometer. The histological scoring was done based on the parameters: basal cell hyperplasia, stromal papillae elongation, cells with irregular nuclear contour (CINC), eosinophilic infiltrate, gastric and intestinal metaplasia. A numerical score was assigned to each parameter and sum of these scores represented the total score. Statistics: The statistical analysis was done using graph pad prism, Medcalc software and Windows MS office. P value and mean standard deviation (SD) was calculated. Results: The endoscopic findings of all the controls and 83.33% of patients were normal. Only 16.67% of patients had reflux associated changes of varying grades on endoscopy. Oesophageal biopsy of all patients had changes related to GERD on histology. Immunohistochemistry confirmed that cells with irregular nuclear contour were T- lymphocytes. The mean (SD) histological scoring of control and patients were 1.75 (0.62) and 5.66 (1.31) respectively. The difference was considered to be statistically significant (P < 0.001). Thus, it was suggested that a cut-off of histological score > 3 can be used to indicate GERD. Conclusion: Patients with gastroesophageal reflux symptoms can have normal endoscopic findings but can be diagnosed on the basis of histological changes in the squamous epithelium. Scoring of the histopathological parameters along with the cut-off value can give a definitive diagnosis of GERD.

Role of Immunohistochemistry and serology in subclassifying the Inflammatory Bowel Disease cases diagnosed as Inflammatory Bowel Diseases---unclassified on colonic biopsies.

Background: Inflammatory bowel diseases (IBDs) mainly consist of Crohn's Disease (CD) and Ulcerative Colitis (UC). These two categories have overlapping histopathological features and sometimes it is difficult to diagnose them into distinct category and such biopsies are categorised as Inflammatory Bowel Disease (IBD-U). Recently, there has been an increase in interest to discover new biomarkers of IBD to differentiate UC and CD and predict their prognosis. Method: In the present study, 273 non-neoplastic colonic biopsies with clinicoendoscopic features of IBD were studied and categorized into UC (88; 32.3%) and CD (03; 1.1%) but a major chunk remained in category of IBD-U (182; 66.6%). 161 (58.9%) of these biopsies were then subjected to IHC for RB protein and ß-catenin and Serology for pANCA and ASCA was done in only 85 (31.13%) of these selected cases for identification of UC and CD on colonic biopsies. Result: 161 biopsies that were subjected to IHC analysis included 57 cases of UC, 03 cases of CD, and rest 101 cases of IBD-U. Out of 101 cases of IBD-U, 87 (86.13%) cases were reclassified as UC (61; 60.3%) and CD (14; 13.86%) on the basis of results of IHC and Serology. Conclusion: The two major tools IHC for ß-catenin and RB protein and the assay of serum ASCA and p-ANCA along with proper history and clinical presentation can act as a good adjunct to conventional H and E in subclassifying cases of IBD-U into UC and CD.

Comparative Study of Sofa, Apache Ii, Saps Ii, as a Predictor of Mortality in Patients of Sepsis Admitted in Medical ICU.

Sepsis is a life-threatening organ dysfunction with high mortality and morbidity. Various mortality prediction scores are currently in use for prediction of mortality. Although combination of various scores have not been used before. The aim of the study was to compare SOFA, APACHE II, SAPS II, as a predictor of mortality and to assess the usefulness of combination of different scores. MATERIAL: A one-year hospital based prospective study conducted from 1st January 2020 to 31st December 2020 in medical ICU, where 100 patients of sepsis admitted in ICU with evidence of organ dysfunction were included in the study and various scores like SOFA, APACHE II, and SAPS II were calculated at 24 and 48 hours of admission, using laboratory results and clinical examination. and an attempt to access for predictive accuracy of combination of scores was undertaken. OBSERVATION: Majority of the patients (37%) were in the age group of 60-79 years with maximum mortality in this age group of (39.22 %). Mortality rate was 51%, with higher mortality in the female group being 68.63%. Diabetes was most common comorbid in our study (41%). No significant difference was observed in physiological variable over 24 and 48 hours, however decrease in WBC and platelet count was noted at the end of 48 hours; Mean SOFA, APACHE II, SAPS II were significantly higher in the mortality group than the recovery group; All three scores had good diagnostic performance, with max sensitivity at 24 and 48 hours with APACHE II being 64.10% and 78.79% respectively, max specificity at 24 and 48 hours was noticed with SAPS II being 96.97% and 87.88% respectively. On further combination of scores, maximum sensitivity was seen with SOFA plus APACHE II at 48 hours of 74.36%, maximum specificity was seen at 24 hours with SOFA plus SAPS II of 93.94%. Upon application of Youden's index to the combination of scores, best diagnostic performance was seen with SOFA plus SAPS II at 48 hours. CONCLUSION: All the three scores showed good mortality prediction rate but among the scores higher sensitivity was seen with APACHE II score at 24 and 48 hours and higher specificity was seen with SAPS II at 24 and 48 hours. Combination of scores did show a slightly better predictability with combination of SAPS II and SOFA showing maximum Youden's index at 48 hours. Mortality was comparatively higher among the females and elderly group with most common risk factor being diabetes.

Study of change in contrast sensitivity in relation to depth of ablation after wavefront optimized myopic laser-assisted in situ keratomileusis.

PURPOSE: The aim of this work was to study the change in contrast sensitivity (CS) in relation to depth of stromal ablation after wavefront-optimized (WFO) myopic laser in situ keratomileusis (LASIK). METHODS: This was as prospective, longitudinal, comparative study. The study participants were divided into two groups: Group 1 ≤50 µ ablation depth; 60 eyes and group 2 >50 µ ablation depth; 60 eyes. All underwent WFO LASIK. Uncorrected and corrected distance visual acuity (UDVA and CDVA) and CS were measured preoperatively and postoperatively at 1 week, 2 weeks, and 2 and 6 months. Two-way repeated-measures analysis of variance (ANOVA), Unpaired t test and one-way repeated measures ANOVA were used to test differences across time periods within each treatment group. A value of P < 0.05 was considered as statistically significant. RESULTS: The mean ablation depths in groups 1 and 2 were 39.30 µ ± 7.22 µ and 69.90 µ ± 12.09 µ, respectively; the maximum depth was 94.62 µ. In group 1, the preoperative mean CS was 1.91 ± 0.07, which improved postoperatively at 1 week (1.93 ± 0.06) and remained stable in subsequent follow-ups (1.94 ± 0.05). In group 2, the mean CS preoperatively was 1.87 ± 0.12, which postoperatively at 1 week and 6 months were 1.93 ± 0.07 and 1.94 ± 0.03, respectively (P < 0.05). Between the groups, preoperative CS was significantly different (P = 0.04), but the change in CS post-LASIK was insignificant (P > 0.05). CONCLUSION: There was a significant improvement in CS after WFO myopic LASIK in all patients irrespective of ablation depth (up to 94.62 µ).

Colitis and Crohn's Foundation (India) consensus statements on use of 5-aminosalicylic acid in inflammatory bowel disease.

Despite several recent advances in therapy in inflammatory bowel disease (IBD), 5-aminosalicylic acid (5-ASA) therapy has retained its place especially in ulcerative colitis. This consensus on 5-ASA is obtained through a modified Delphi process, and includes guiding statements and recommendations based on literature evidence (randomized trials, and observational studies), clinical practice, and expert opinion on use of 5-ASA in IBD by Indian gastroenterologists. The aim is to aid practitioners in selecting appropriate treatment strategies and facilitate optimal use of 5-ASA in patients with IBD.

Diet and inflammatory bowel disease: The Asian Working Group guidelines.

INTRODUCTION: These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries. METHODOLOGY: The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. RESULTS: Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation. CONCLUSIONS: Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.

Role of opioids as coinduction agent with propofol and their effect on apnea time, recovery time, and sedation score.

BACKGROUND: Laryngeal mask airway (LMA) is a supraglottic device which requires lesser depth of anaesthesia, evokes lesser hemodynamic response and causes lesser stimulation of airway as compared to traditional definitive airway device endotracheal tube. Its placement is possible without muscle relaxants thereby allowing maintenance of anaesthesia on spontaneous respiration thus preventing apnoea or minimizing apnoea time. Propofol, the commonly used induction agent, causes cardiorespiratory depression at higher induction doses. To attenuate this, co-induction agents combined with propofol has been a regular I/V anaesthetic technique these days. AIM: Comparing apnoea time, recovery time and sedation scores using propofol-fentanyl and propofol-butorphanol combination. METHODOLOGY: Hundred patients scheduled for various elective surgical procedures were randomly selected and divided into two groups of 50 each. As coinduction drug Group F received fentanyl and Group B received butorphanol. In both the groups induction was achieved with I/V propofol and LMA was placed. Apnoea time was noted after induction. Recovery time and sedation scores were recorded after anaesthetic agents were turned off. RESULTS: As compared to group F apnoea time was significantly less and recovery time was significantly more in group B (P < 0.05). Statistically postoperative sedation was significantly higher in group B than in group F at 1/2 hr but clinically, majority were responding to verbal commands. At 1 hour no significant difference in sedation was noted between the groups. CONCLUSION: Considering respiratory and recovery profile propofol -butorphanol combination is a safer alternative to propofol-fentanyl combination for LMA insertion.

Differentially localized survivin and STAT3 as markers of gastric cancer progression: Association with Helicobacter pylori.

BACKGROUND: Localization and differential expression of STAT3 and survivin in cancer cells are often related to distinct cellular functions. The involvement of survivin and STAT3 in gastric cancer has been reported in separate studies but without clear understanding of their kinetics in cancer progression. METHODS: We examined intracellular distribution of STAT3 and survivin in gastric adenocarcinoma and compared it with normal and precancer tissues using immunoblotting and immunohistochemistry. RESULTS: Analysis of a total of 156 gastric samples comprising 61 histologically normal, 30 precancerous tissues (comprising intestinal metaplasia and dysplasia), and 65 adenocarcinomas, collected as endoscopic biopsies from treatment naïve study participants, revealed a significant (P < .001) increase in overall protein levels. Survivin expression was detectable in both cytoplasmic (90.8%) and nuclear (87.7%) compartments in gastric adenocarcinomas lesions. Precancerous dysplastic gastric lesions exhibited a moderate survivin expression (56.7%) localized in cytoplasmic compartment. Similarly, STAT3 and pSTAT3 expression was detected at high level in gastric cancer lesions. The levels of compartmentalized expression of survivin and STAT3/pSTAT3 correlated in precancerous and adenocarcinoma lesions. Although overexpression of these proteins was found associated with the tobacco use and alcohol consumption, their expression invariably and strongly correlated with concurrent Helicobacter pylori infection. Receiver operating characteristic analysis of nuclear survivin, STAT3, and pSTAT3 in different study groups showed acceptable positive and negative predictive values with area under the curve above 0.8 (P < .001). CONCLUSION: Overall, our results suggest that overall increase in survivin and STAT3 and their subcellular localization are key determinants of gastric cancer progression, which can be collectively used as potential disease biomarkers and therapeutic targets for gastric cancer.

Levels of interleukins 2, 6, 8, and 10 in patients with irritable bowel syndrome.

Irritable bowel syndrome (IBS) was previously considered as a psychosomatic disorder. But recent studies indicate that inflammation plays a significant role. The present study was undertaken to evaluate role of pro-inflammatory (IL 2, IL 6 and IL 8) and anti-inflammatory (IL 10) cytokines in clinically diagnosed patients of IBS. 51 patients and 29 controls were included in this study. On the basis of history of gastrointestinal infection, patients were divided into Post Infectious (PIIBS) and Non Post Infectious (NPIIBS) groups. All subsequently underwent colonoscopy and a rectosigmoid biopsy as well as measurement of levels of IL 2, 6, 8 and 10. The levels of IL 2 and IL 8 were significantly raised in IBS patients compared to controls with the mean level of IL 2,6 and 8 higher in PIIBS group than NPIIBS group but statistically significant for IL 8 only. The mean level IL-10 was reduced in patients compared to controls but statistically insignificant. Present study shows that Interleukin levels are altered in patients suffering from IBS and may have a key role in its pathogenesis.

Irritable Bowel Syndrome and Bronchial Asthma: Are They Associated in Indian Population?

INTRODUCTION: Irritable Bowel Syndrome (IBS), a common gastrointestinal (GI) disorder has been linked with asthma implying a clue to its pathophysiology as being some form of allergic response. Previous studies from other parts of the world have shown both the presence as well as an absence of an association between them. AIM: We conducted a cross-sectional study to find an association between IBS and asthma, in an Indian cohort. MATERIALS AND METHODS: Seventy patients of IBS diagnosed by exclusion and ROME III criteria with a matched control group were questioned for GI, respiratory symptoms along with their spirometry analysis. Those having reversible bronchoconstriction were categorized as asthmatic. RESULTS: The prevalence of asthma in the IBS group of 16 females and 54 males was 12 (17.14%) as compared to 14 (20%) in control group. Chi-square test revealed the Odds Ratio (OR) for prevalence of asthma in IBS as 0.828 with 95% Confidence Interval (CI) between 0.320 and 2.121 (p=0.664) which was non-significant (p>0.05). CONCLUSION: This study denies the presence of association between IBS and asthma among Indian cohorts and suggests that regional variations are present in the above association.

Vitamin D status in patients with cirrhosis of the liver and their relatives-A case control study from North India.

BACKGROUND AND AIM: Liver diseases interfere with the production of the metabolites of vitamin D required for activation, thus resulting in abnormal calcium and bone metabolism. Previous studies show inconsistent results of vitamin D level in non-cholestatic liver diseases. Our aim was to determine the prevalence of vitamin D insufficiency in cirrhosis as compared to apparently normal relatives and its relationship with etiology and severity. METHODS: One hundred and sixty cirrhotic patients attending the Department of Gastroenterology and Hepatology, M L N Medical College, Allahabad, were enrolled, and 25-hydroxy vitamin D [25(OH)D] and calcium levels assessed. Vitamin D status was graded as insufficiency (20-30 ng/mL), deficiency (<20 ng/mL), and severe deficiency (<7 ng/mL). 25(OH)D levels of patients were compared with those of their healthy family members. RESULTS: Forty-six percent of the normal population had 25(OH)D inadequacy, whereas 51.85% of patients with cirrhosis had 25(OH)D deficiency, and 28.12% had insufficiency. Thus, 80% of patients with cirrhosis of the liver had some form of vitamin D inadequacy. 12.5% of cirrhotics had severe vitamin D deficiency. Serum calcium (Ca++) was not significantly different between the patients and control group. The etiology of cirrhosis had no relation with vitamin D levels. Prevalence of deficiency and insufficiency increased with increasing age and mean Child-Turcotte-Pugh and model for end-stage liver disease scores. CONCLUSION: Vitamin D insufficiency is highly prevalent in patients with cirrhosis irrespective of etiology and significantly more common than their healthy relatives. Measurement of 25(OH) vitamin D and replacement may be considered as part of the overall management of patients with cirrhosis of the liver as well as apparently healthy individuals.

Expression of Alpha Methylacyl CoA Racemase (AMACR) in Gastric Adenocarcinoma and Its Correlation with Helicobacter pylori Infection.

INTRODUCTION: Gastric cancer develops in a multistep progression and is determined by genetic and environmental factors. Over-expression of Alpha Methylacyl CoA Racemase (AMACR) is useful in diagnosis of prostate cancer. There is plenty of genetic alteration that occurs in gastric adenocarcinoma. The present study was planned to determine if AMACR can be used as a diagnostic marker in gastric adenocarcinoma similar to prostate cancer. AIM: To study the expression of AMACR in gastric adenocarcinoma and correlate its expression with density of Helicobacter pylori. MATERIALS AND METHODS: This cross-sectional, prospective study was conducted from August 2013-2015. Fifty gastric cancer biopsies were taken. Adjacent biopsy from normal/reactive mucosa was also taken from 21 cases. Samples were stained with H&E for morphological details, Loeffler's methylene blue for Helicobacter pylori and immunohistochemistry (IHC) was done to check for the expression of AMACR proteins. Statistical analysis was done using chi square test, Spearman's correlation coefficient and Fisher's exact test. The p-value ≤ 0.05 was taken as critical level of significance. RESULTS: Overexpression of AMACR was observed in 88.89% of intestinal type and 78.05% of diffuse type adenocarcinoma. AMACR expression was significantly less in adjacent reactive/dysplastic mucosa. Helicobacter pylori were seen in 8/9 (88.89%) and 35/41(85.36%) cases of intestinal adenocarcinoma and diffuse adenocarcinoma respectively. When grades of Helicobacter pylori were compared with the positivity of AMACR, no significant association and correlation was found. CONCLUSION: The expression of AMACR in neoplastic tissue was significantly higher as compared to adjacent dysplastic, reactive or normal tissue. Thus, IHC for AMACR can be used for differentiating the cases of reactive atypia from early neoplastic lesions similar to its role in prostatic tissue. Helicobacter pylori does not affect the expression of AMACR in neoplastic gastric lesions.

What happens to the hemodynamic responses for laryngeal mask airway insertion when we supplement propofol with butorphanol or fentanyl for induction of anesthesia: A comparative assessment and critical review.

BACKGROUND: There is a delicate balance between respiratory tract anatomy, its physiology, physiological response to anesthetic agents, and airway management. The traditional gadgets to secure airway are face masks or endotracheal tubes. Recently, laryngeal mask airway (LMA) is gaining popularity. It does not require laryngoscopy thereby minimizing hemodynamic responses. For LMA placement, propofol is the induction agent of choice. Propofol, when used alone, requires large doses and leads to undesirable cardiorespiratory depression. To culminate its dose, various adjuncts are combined with it. AIM: Comparison of hemodynamic response of LMA using either butorphanol or fentanyl (according to group allocated) in combination with propofol. METHODOLOGY: Hundred patients scheduled for various surgical procedures were randomly selected and divided into two groups of 50 patients each, Group F (propofol and fentanyl) and Group B (propofol and butorphanol). One minute after giving intravenous (IV) opioids, induction was achieved with IV propofol 2.5 mg/kg. Depth of anesthesia was assessed, and LMA was inserted. Hemodynamic variables were measured before premedication, after premedication; 1, 3, and 5 min after insertion and after extubation of LMA. RESULTS: After insertion of LMA, statistically significant drop in mean heart rate, systolic blood pressure (BP), diastolic BP, and mean BP was noted in Group F as compared to Group B (P < 0.05). CONCLUSION: The use of propofol-butorphanol combination produces stable hemodynamics as compared to propofol-fentanyl combination.

Berberine and Curcumin Target Survivin and STAT3 in Gastric Cancer Cells and Synergize Actions of Standard Chemotherapeutic 5-Fluorouracil.

Aberrantly expressed survivin and STAT3 signaling have emerged as major determinants of chemoresistance in gastric cancer. We evaluated effects of potent herbal derivatives curcumin, berberine, and quercetin on STAT3 signaling, survivin expression, and response to 5-fluorouracil (5-FU) treatment in gastric cancer cells (AGS). Cytotoxic and inhibitory effects of berberine, curcumin, and quercetin alone or in combination with 5-FU were examined by MTT assay, and their effect on survivin, STAT3, and the phosphorylated active STAT3 (pSTAT3) expression was examined by western blotting. Effect of these herbal derivatives on STAT3 DNA binding activity was measured by electrophoretic mobility shift assay. Curcumin, berberine, and quercetin effectively downregulated pSTAT3 levels, survivin expression, and gastric cancer cells viability in a dose-dependent manner (with corresponding IC50 values of 40.3µM, 29.2µM and 37.5µM, respectively). Berberine was more effective in inhibiting survivin expression as compared to other herbal agents. 5-FU in combination with berberine or curcumin showed a synergistic inhibition of survivin and STAT3 level resulting in enhanced cell death in gastric cancer cells. Overall, our data suggest use of berberine and curcumin as adjunct therapeutics to overcome chemoresistance during treatment of gastric malignancies.

Efficacy and safety of drotaverine hydrochloride in irritable bowel syndrome: a randomized double-blind placebo-controlled study.

BACKGROUNDS/AIMS: To study the efficacy and safety of drotaverine hydrochloride (HCl) 80 mg tablet given thrice a day in the symptomatic relief of patients with irritable bowel syndrome (IBS). PATIENTS AND METHODS: The study was a multicentric, randomized, double-blind, placebo-controlled parallel group study performed at three centers. The patients who fulfilled Rome II Criteria of IBS were included in the study. A total of 180 patients with IBS were randomized to drotaverine and placebo treatment groups. Abdominal pain and stool frequency were measured every week in both the groups for all the 4 weeks of treatment duration. Subject Global Assessment of Relief (SGA) of IBS symptoms was assessed at the end of the study. Appropriate statistical analysis was done using SPSS software. STATISTICAL ANALYSIS USED: Mann-Whitney U-test (two-tailed), Wilcoxon signed ranks test, and McNemar tests. RESULTS: Pain frequency decreased significantly (P < 0.01) in 22 (25.9%), 51 (60%), and 66 (77.7%) patients in the drotaverine group, at the end of 2nd, 3rd, and 4th weeks, respectively, as compared with 8 (9.4%), 18 (21.2%), and 26 (30.6%) in the placebo group. Pain severity scores also decreased significantly in the drotaverine group 66 (77.7%) as compared with placebo 26 (30.6%) after 4 weeks. Drotaverine HCl was shown to provide significant improvement (P < 0.01) in global relief in abdominal pain as perceived by the patient (85.9% vs 39.5%) and the clinician (82.4% vs 36.5%) in the drotaverine group as compared with placebo. There is significant (P < 0.01) improvement in stool frequency in drotaverine HCl treatment group as compared with placebo. The drug is well tolerated without any major side effects. CONCLUSIONS: A 4-week treatment with drotaverine significantly improves abdominal symptoms in patients with IBS.

Helicobacter pylori infection and a P53 codon 72 single nucleotide polymorphism: a reason for an unexplained Asian enigma.

AIM: P53, the most commonly mutated tumor suppressor gene in all types of human cancer, is involved in cell cycle arrest and control of apoptosis. Although p53 contains several polymorphic sites, the codon 72 polymorphism is by far more common. There are divergent reports but many studies suggest p53 pro/pro SNP may be associated with susceptibility to developing various cancers in different regions of the world. The present study aimed to find any correlation between H. pylori infection and progression of carcinogenesis, by studying apoptosis and the p53 gene in gastric biopsies from north Indian population. MATERIALS AND METHODS: A total of 921 biopsies were collected and tested for prevalence of H. pylori by rapid urease test (RUT), imprint cytology and histology. Apoptosis was studied by the TUNEL method. Analysis of p53 gene polymorphism at codon 72 was accomplished by PCR using restriction enzyme BstU1. OBSERVATION: Out of 921 samples tested 56.7% (543) were H. pylori positive by the three techniques. The mean apoptotic index (AI) in the normal group was 2.12, while gastritis had the maximum 4.24 followed by gastric ulcer 2.28, gastropathy 2.22 and duodenal ulcer 2.08. Mean AI in cases with gastric cancer (1.72) was less than the normal group. The analysis of p53 72 SNP revealed that p53 (Arg/Arg), (Pro /Arg) variant are higher (40.59% and 33.66%) as compared to p53 pro/pro variant (25.74%) in the healthy population. CONCLUSIONS: The North Indian population harbors Arg or Pro/Arg SNP that is capable of withstanding stress conditions; this may be the reason of low incidence of gastric disease in spite of high infection with H. pylori. There was no significant association with H. pylori infection and AI. However, there is increased apoptosis in gastritis which may occur independent of H. pylori or p53 polymorphism.
