Trait emotional intelligence as predictor of psychological health in undergraduate medical students: A hierarchical multiple regression approach

Objectives: Trait emotional intelligence (TEI) is a key personality construct by which an individual recognizes, understands, expresses and regulates emotions in self and others to adapt to environments or achieve one’s goals. TEI skills are modifiable and have a potential to significantly influence psychological health (PH) of a person. The aims of current work were to evaluate relationship between TEI and PH of medical students and to explore the incremental validity of TEI to predict psychological distress beyond sociodemographic and educational factors in them. Materials and Methods: One hundred and thirty-two medical students (mean age 18.02 years) participated in this cross-sectional study. TEI and PH were assessed using TEI questionnaire short form (TEIQue-sf) and depression, anxiety and stress scale (DASS-21), respectively. Hierarchical multiple regression analysis was carried out to determine if scores on TEIQue-sf added significantly to the prediction of psychological symptoms in medical students. Results: There was a significant negative association (r = ?0.57, P < 0.001) between TEIQue-sf and DASS-21 scores. Hierarchical regression analyses revealed that after controlling for sociodemographic and educational variables, TEIQue-sf scores explained a statistically significant increment of variance (P < 0.001) in DASS-21 scores. TEI emerged as best predictor of psychological distress of medical students followed by educational factors. However, sociodemographic profile as an attribute failed to demonstrate significant capacity to predict PH of our participants. Conclusion: Our results indicate that TEI is a robust and unique predictor of better PH and plays a positive role in promoting psychological well-being

An atypical Trypanosoma lewisi infection in a 22-day-old neonate from India: An emergent zoonosis

Reports on atypical human trypanosomiasis, caused by Trypanosoma lewisi, are rare and so far a total of 19 reports on human infection with animal trypanosomes, which includes nine cases from Trypanosoma lewisi exist. Trypanosoma lewisi, a Stercorarian trypanosoma of rats, is transmitted by the fecal contamination of the wound or the bite caused by rat flea Ceratophyllus fasciatus. We report here an atypical neonatal infection of T. lewisi in a 22-day-old infant from Agra. The infant presented with a history of high fever, poor appetite, and lethargy for 3 days. The hematological parameters were normal except for a low platelet count. A high C-reactive protein (CRP) concentration of 70.49 mg/L indicated marked inflammation. The Leishman-stained thin blood smears were microscopically positive for the hemoflagellate. Based on the morphological features and further confirmed by polymerase chain reaction (PCR) assay, the hemoflagellate was identified as T. lewisi. Symptomatic treatment and antibiotic therapy helped in an uneventful recovery of the patient.

Impact of COVID-19 pandemic on medical education

Background: Medicine is one of the few academic disciplines that cannot be taught in the distance education mode. Hands-on practice for clinical skills and competency is critical in medical education. Although this pandemic has offered new learning modes such as teleconsultation, videoconferencing, virtual simulations, and digital podcasts, how much actual knowledge transfer and skill gain will be achieved, is unanswered. Aims and Objectives: The present study has been planned to understand the impact of COVID on medical education and to identify the factors which promoted or hindered learning during COVID-19 pandemic. Materials and Methods: This cross-sectional study was conducted among 261 willing MBBS students from various colleges of Tamil Nadu after obtaining Institutional Ethical committee clearance using a pre-validated structured online questionnaire through Google form link in online social platforms through “Voluntary opt in” method of sampling. Results: About 22.6% of the study participants were affected by COVID-19. About 46% of the participants family members suffered from COVID and all of them accepted that it significantly affected their academics. About 71.6% experienced anxiety/depression. About 93.5% were addicted to social media during class hours. About 88.1% welcomed “flipped/blended learning”. More than 90.8% reported that they missed skill-based learning/Primary health care training. About 80.8% positively felt that they got more duration for preparing exams. About 89.3% found that practical exams were challenging. Conclusion: Not only have we witnessed the importance of having a robust health-care system, but the pandemic has created a critical need to transform various aspects of medical education especially to a model of blended learning of online and offline methods to enable a better academic environment so as to reflect the changing medical landscape.

VEGETATIVE GRANULOMA : A DIAGNOSIS SELDOM SUSPECTED CLINICALLY

Vegetative granuloma is granulomatous foreign body response to impaction of vegetative or plant material in periapical and sulcus areas of oral cavity, generally secondary to trauma and/or poor oral hygiene. Other names being used in literature for vegetative granuloma are pulse granuloma, chronic mandibular periostitis, hyaline ring granuloma and giant cell hyaline angiopathy. Most cases are seldom suspected clinically and confirmed by microscopic examination only. We present here a case of 42 years old female with peanut sized nodular swelling over left maxilla associated with gradually increasing pain since 3 months. Her oral examination revealed poor oral hygiene. Radiological investigation depicted soft tissue swelling without any bony involvement. Histomorphology showed tissue lined by hypertrophied stratified squamous epithelium having vegetative matter impacted in fibro-collagenous stroma surrounded by prominent giant cell reaction with well-formed granulomas, suggestive of diagnosis of vegetative granuloma. It is important to correctly diagnose this entity as it is an uncommon one and rarely encountered in routine practice. It may clinically mimic as malignancy or tuberculosis at times, hence an accurate diagnosis saves from undue over treatment. Vegetative granuloma is treated by complete excision of lesion and maintenance of oral hygiene to prevent recurrence.

Protective Effect Of Diosgenin On Streptozotocin Induced Diabetic Nephropathy In Experimental Rats

Diabetes mellitus is a multifactorial metabolic disorder associated with the diabetes related vascular diseases. Oxidative stress along with inflammation is the Key factor leading to diabetic complications. Present study was designed to investigate the protective role of diosgenin, a steroidal saponin, in diabetes induced early kidney injury and oxidative stress markers and histopathological changes in kidney of diabetic rats, induced by single intra-peritoneal injection of streptozotocin (55 mg/kg weight (b.w.). After 72 hrs, experimental rats received diosgenin at different doses (10, 20 and 40 mg/kg b.w.) once daily for four weeks. At the end of the experiment, diabetic rats showed a significant increase in the levels of plasma glucose, glycosylated hemoglobin with a significant decrease in insulin and total hemoglobin. The activities of antioxidant enzymes such as superoxide dismutase, catalase, reduced glutathione, and the levels of reduced glutathione were decreased while increases in the levels of lipid peroxidation markers were observed in kidney tissues of diabetic rats. Oral administration of diosgenin to diabetic rats considerably shrivelled the plasma glucose and exaggerated the endocrine level supported a dose dependent manner. Diosgenin at a dose of 40 mg/kg b.w. was more pronounced effect than the other two doses and used for further studies. All the manifestations observed in diabetic rats were significantly reversed to near normal at a dose of 40 mg/kg b.w. of diosgenin. These findings recommend that diosgenin may have a helpful role against excretory organ harm evoked by aerobic stress within the diabetic state.

Cellular mesenchymal epithelial transition (C-MET) gene copy number variation in gastric adenocarcinoma: A pilot search for new marker for targeted therapy in HER-2/neu resistance

Increasing HER-2/neu resistance in gastric carcinoma has encouraged search for new biomarkers for targeted therapy. Cellular mesenchymal epithelial transition (C-MET) is one such tyrosine kinase inhibitor proposed for personalized salvage treatment. We determined frequency of C-MET gene copy number variation (CNV) by Fluorescent in-situ hybridization (FISH) in gastric adenocarcinoma (GAC) and sought its correlation with conventional clinicopathologic parameters. Dual-coloured FISH was done on 32 GAC cases. C-MET gene and centromere 7 signals were counted under fluorescent microscope and ratio was calculated for each case. Correlation between C-MET CNV and conventional clinic-pathologic parameters was done by Fischer exact test. CNV was identified in the form of amplification and polysomy (3.1% each) and associated with poorer prognostic parameters. Our pilot study highlights limited subset of patients that may benefit from anti-C-MET-targeted therapy and thus could be a novel biomarker for targeted intervention in GAC.

Comparative study of postoperative analgesia by epidural ketamine and ketamine plus dexamethasone in lower limb orthopedic surgery

Aim & Objectives: To compared the effect of ketamine and combination of ketamine plus dexamethasone on the duration of postoperative analgesia and to evaluate the effect of dexamethasone on postepidural backache and other complications. Methods: 50 patients (ASA I and II) posted for elective surgery of lower limb in orthopedics, were divided at random into two groups of 25 each. Patients in group I received Inj. Ketamine HCl 0.3 mg/kg diluted in 10 ml normal saline while patients in group II received ketamine HCl 0.3 mg/kg and dexamethasone 8 mg diluted in 10 ml normal saline postoperatively through epidural catheter. The relief of pain and perioperative sequelae were compared. Results: Groups were compared with respect to quality of epiduralanaesthesia and pain relief as felt by the patient. The quality of epidural anaesthesia was found adequate in 80% cases of group 2 and 76% cases of group 1. Pain relief was 20% excellent and 76% good in group 2 and 12% excellent and 68% good in group 1. In group I the mean duration of pain relief after epidural injection of ketamine 0.3 mg/kg was 363.91±180.94 min and in group II after epidural injection of ketamine 0.3 mg/kg with dexamethasone 8 mg was 582.63±182.03 min. These values differ markedly and are statistically highly significant (p<0.001). Conclusion: Ketaminecan be used epidurally safely for rapid onset and is effective for prolonged postoperative analgesia with minimum side effects and high acceptability. The duration can be further prolonged with the addition of dexamethasone and the incidence of postepidural backache is also minimised with dexamethasone.

Iris varix: 10-year experience with 28 eyes

Purpose: The purpose of this study is to describe the clinical characteristics, multimodality imaging findings, and clinical course of iris varices. Methods: Retrospective, noncomparative, observational case series of 28 eyes of 26 patients with iris varices, diagnosed between 2007 and 2017, has been used. Results: The mean (±SD) age was 58.3 ± 12.5 years (median 57.5, range 37–81). Patients were 57.7% male and 27% hypertensive. Varices were bilateral in two patients. The mean and median visual acuities were both 20/20 (range 20/16–20/40). Intraocular pressures were 16 mmHg (10–23 mmHg). Secondary glaucoma did not occur. The inferotemporal iris quadrant was affected in 75%. A single varix was seen in 64% and 36% appeared multiple. Varix orientation was radial in 57% and circumferential in 21%. Combined radial and circumferential varix orientation was noted in 18%. One had independent radial and circumferential varices in separate quadrants. A single episcleral sentinel blood vessel directed to the varix was present in 36%. Ultrasound biomicroscopy (UBM) showed a slightly increased mean iris thickness of 0.8 mm and multiple echolucent iris stromal vascular channels. Iris angiography showed no leakage of dye. Managed by observation over a mean follow-up of 37.7 months (range, 3–129), 96.4% eyes were stable and one (3.6%) regressed. No corectopia, ectropion uveae, hyphema, or metachronous anterior segment benign or malignant tumors occurred. Conclusion: Iris varix is primarily located in the inferotemporal quadrant and not associated with dysmorphic pupillary findings, progression, secondary glaucoma, or malignancy. Iris varices were benign vasculopathies with no associated ocular or vision-related morbidity.

Conjunctival myxoma: A case report with unique high frequency ultrasound (UBM) findings

A 39-year-old female presented with a painless yellow-pink tumor on her right eye. High-frequency ultrasound imaging revealed an epibulbar lesion with homogenous low internal reflectivity and no evidence of intraocular invasion. The patient underwent excisional biopsy leading to a pathology diagnosis of myxoma. Additional surgical margins as well as adjuvant cryotherapy margins were followed by extensive conjunctival repair. Herein, we report on a conjunctival myxoma with unique ultrasonographic findings.

Long-term efficacy and safety of verteporfin photodynamic therapy in combination with anti-vascular endothelial growth factor for polypoidal choroidal vasculopathy

Purpose: The aim of the study was to analyze the outcomes of photodynamic therapy (PDT) with intravitreal anti-vascular endothelial growth factor (anti-VEGF) for patients with polypoidal choroidal vasculopathy (PCV) having visual acuity (VA) better than 20/60 in a real-world scenario in India. Methods: Retrospective review of 42 eyes of 40 patients (mean age 64.3 years) with best-corrected VA (BCVA) 20/60 or better and mean follow-up of 40 months (median 38 months; range 12� months) treated with PDT and anti-VEGF or triamcinolone for indocyanine green angiography (ICGA)-proven subfoveal PCV. Results: Mean BCVA improved from 0.22 logMAR at baseline to 0.15 at last visit (P < 0.001). On ICGA, polyp was observed in 42 eyes (100%) and branching vascular network (BVN) in 37 eyes (88.1%). Polyp regressed in 33 (78.6%) of 42 eyes and BVN in 26 (70.3%) of 37 eyes after combined therapy at 3 months. Mean greatest linear diameter reduced significantly (P < 0.001) from 7.22 mm to 4.11 mm. Standard-fluence PDT was performed in 35 eyes and reduced-fluence in 7 eyes. The mean number of PDT was 1.17 with mean number of injections being 6.38 at the end of follow-up. In five eyes, more than one PDT was administered. Of 42 eyes, 40 showed complete resolution of serous macular detachment (SMD) after the combined therapy at 3 months; 17 (42.5%) of the 40 eyes showed no recurrence of fluid on spectral domain optical coherence tomography till the last visit with a mean follow-up of 27 months. On long-term follow-up, SMD reoccurred in 23 eyes with a mean follow-up period of 9.64 � 5.24 months. Of 38 eyes having a double-layer sign (DLS) on optical coherence tomography at baseline, 37 eyes were having regression of the DLS, that is, it either reduced or resolved at the final visit. At the final visit, 66.7% (P < 0.001) eyes were having fluid-free retina. No complication of subretinal hemorrhage was noted. Of the 42 eyes, only one eye had BCVA worse than 20/60 on the final visit. Conclusion: To the best of our knowledge, this is the first study to look into the long-term effect of combined PDT with anti-VEGF in PCV in eyes having good VA. Long-term effect of combined PDT appears to be a safe and effective treatment for PCV in eyes having good VA with better outcomes in real-world setting. This study further strengthens the superiority of the combined treatment modality for treatment of subfoveal PCV with no or minimal risk of complication on long-term follow-up.

Spectral domain optical coherence tomography evaluation of macular changes in Eales disease

Purpose: The purpose of the study was to describe macular changes in treatment-naïve eyes with Eales disease using spectral domain optical coherence tomography (SD-OCT). Methods: A cross-sectional study was done on 79 eyes of 66 patients with Eales disease. Best-corrected visual acuity (BCVA), slit-lamp biomicroscopy (SLB), indirect ophthalmoscopy, fundus fluorescein angiography (FFA), and quantitative (central macular thickness [CMT]) and qualitative analysis on SD-OCT were performed. Results: Forty-six (58.2%) eyes had macular involvement as assessed with SD-OCT, while in 33 (41.8%) eyes, macula was not affected. Macular edema was the most common feature when macula was affected followed by epiretinal membrane. Mean CMT was higher (315.3 ± 102.3 ?m) in eyes with macular involvement than those without it (243.8 ± 19.3 ?m). Eyes with active vasculitis involving larger vessels and neovascularization had greater chance of macular involvement. SLB and FFA alone missed 28.3% and 50% eyes with macular abnormalities on SD-OCT, respectively. Conclusion: While the clinical description of Eales disease points mainly to a peripheral location, macular involvement can be commonly picked up when SD-OCT is used. Macular involvement when present is associated with a poorer BCVA.

Trend of human brucellosis over a decade at tertiary care centre in North Karnataka.

Background: Brucellosis is an important zoonotic disease. India having a major agrarian population is expected to have a higher prevalence. However, due to lack of laboratory facility or awareness among clinicians, the disease is largely underreported. The aim of this study was to know the prevalence and trend of human brucellosis over a decade, in patients attending a teaching hospital in North Karnataka, and to understand their geographical distribution. Materials and Methods: The study was conducted from January 2006 to December 2015 at a tertiary care teaching hospital in North Karnataka. A total of 3610 serum samples were evaluated from suspected cases of brucellosis. All serum samples were initially screened by Rose Bengal plate test, and positive samples were further analysed by Serum agglutination test (SAT) using standard Brucella abortus antigen from Indian Veterinary Research Institute, Izatnagar, Uttar Pradesh, India. A titre above or equal to 1:80 IU/ml was considered as positive. Demographic data such as age, sex and native place of these patients were also analysed. Results: We observed that human brucellosis is present in North Karnataka. The overall seropositivity of brucellosis in suspected cases was 5.1%. The positive titres ranged from 1:80 to 163,840 IU/ml. The majority of the patients were from Gadag, Koppal and Haveri districts of North Karnataka. Conclusion: Our study confirms the presence of human brucellosis in the northern part of Karnataka. Further studies to understand the prevalence of animal brucellosis in these areas will help in implementing prevention measures.

Sunitinib in patients with imatinib‑resistant gastrointestinal stromal tumor: A single center experience.

AIM: The outcome of patients with advanced gastrointestinal stromal tumor (GIST) has improved with the use of imatinib. Despite high response rates with this drug resistance eventually develops in nearly all patients. We present an analysis of prospectively collected data on sunitinib efficacy and safety in patients with imatinib‑resistant GIST. SUBJECTS AND METHODS: Between November 2006 and October 2007, patients with GIST were accrued in an approved sunitinib patient access protocol. Key eligibility criteria included tumor resistance to imatinib and/or patient intolerance to this drug. Patients received sunitinib at a starting dose of 50 mg once daily for 4 weeks in a 6 week cycle, with standardized dose modification titrated to toxicity. Patients were continued on sunitinib until disease progression or unacceptable toxicity. The endpoints were safety, overall survival (OS) and objective response rate (ORR). RESULTS: Fifteen patients, all of whom had imatinib resistance and none intolerance, with median age of 48 (26–69) years, were treated on the protocol. The most common sites of primary disease were small intestine (40%), stomach (26.7%) and retroperitoneal (26.7%). A median of 10 (1–47) cycles of sunitinib were delivered, 9 (60%) patients required dose reductions due to toxicity whereas dose delay of > 2 weeks was required in only one (6.7%) patient. There were no toxicity‑related drug discontinuations. Hypothyroidism (n = 4; 26.7%) and hand‑foot syndrome (n = 3; 20%) were the most common toxicities. There were no complete and 4 (26.7%) partial responses while prolonged disease stability was seen in 8 (53.3%) patients. At a median follow‑up of 81 months in surviving patients, the median progression‑free and overall survivals were 15.5 and 18.7 months, respectively. CONCLUSIONS: Sunitinib appears to be an effective and well‑tolerated treatment for Indian patients with imatinib‑resistant GIST with outcomes similar to that reported previously. Adverse effects can be reasonably well managed using a dose modification strategy.

Use of Traditional Indian Plants in the Inhibition of Caries-Causing Bacteria - Streptococcus mutans

The aim of the study was to comparatively evaluate the antibacterial activity of six Indian plant extracts and 0.2% chlorhexidine against clinical strains of Streptococcus mutans, which were isolated from the plaque samples of 45 pediatric patients. Six plant extracts were prepared in three different forms, namely aqueous extracts, organic solvent-based extracts and crude (raw) extracts. The antimicrobial sensitivity testing was done by agar well diffusion method. Antimicrobial activity of the extracts was determined by measuring the mean zones of inhibition (mm) produced against the bacterial isolates. Results showed that crude garlic extract exhibited greater antibacterial activity than chlorhexidine. Aqueous extract of amla and organic solvent-based extract of ginger showed the maximum antibacterial activity against S. mutans, whereas aqueous extract of tulsi and organic solvent based extract of amla showed the minimum antibacterial activity. This study suggests that plant extracts like garlic in crude form, amla as aqueous infusion and ginger as alcoholic tincture have potential for the control of S. mutans. These extracts can be used as an alternative remedy for dental caries prevention or in the form of mouthwash, which is safe and economical.

O objetivo do estudo foi avaliar comparativamente a atividade antibacteriana de seis plantas indianas contra linhagens clínicas de Streptococcus mutans, que foram isoladas das amostras de biofilme dental de 45 pacientes pediátricos, com 0,2% de clorexidina. Seis extratos vegetais foram preparados em três formas diferentes, a saber, extratos aquosos, extratos à base de solventes orgânicos e extratos brutos. Os testes de sensibilidade antimicrobiana foram realizados por método de difusão em agar. A atividade antimicrobiana dos extratos foi determinada através da medição da zona de inibição, em milímetros, produzida contra os isolados bacterianos. Os resultados mostraram que o extrato de alho cru apresentou maior atividade antibacteriana do que a clorexidina. O extrato aquoso de amla e o extrato à base de solventes orgânicos de gengibre mostraram a máxima atividade antibacteriana contra S. mutans, enquanto o extrato aquoso de tulsi (manjericão) e o extrato à base de solventes orgânicos de amla mostraram mínima atividades antibacteriana. Este estudo sugere que extratos de plantas como o alho em forma bruta, amla como infusão aquosa e gengibre como tintura alcoólica tem um potencial para o controle de S. mutans. Estes extratos podem ser utilizados como uma via alternativa para a prevenção de cáries dentárias ou sob a forma de bochechos, que são seguros e econômicos.
