    (2016-01) Kumar, Sudhir; Kumar, Govind; Ahmad, Arshad; Ranjan, Ashish; Mishra, Amit; Barat, D
    Background & Objective: Among various method of medical education integrated teaching help in integration of basic, clinical and psychosocial sciences. Integrated teaching involves bringing together traditionally separate subjects so that students can grasp subject with more authentic understanding. We conducted the study to compare this scientific method of teaching with traditional learning and also obtained student’s and teacher’s feedback. Methodology: After approval from ethic committee faculty members from various departments we arranged integrated teaching program on important topic. Basic science faculty were made toparticipate actively in both case based learning and hospital visits along with clinical experts. The completed program was evaluated based on structured questionnaire and student and teacher feedback. Results: Among 58 students of 8th semester students, Pre test (TL) and post test (IL) mean of incorrect answers out of 10 structured questionnaires were 4.5517 and 2.9310. There was 35.5% improvement in result after integrated method of learning. 63% of faculty members felt that integrated teaching could be very useful. 85% students were enthusiastic about the new teaching methodology& felt that they had a better clinico pathological correlation. Conclusion: The new method of integrated teaching was found to be more effective than the traditional one. This method was well accepted by faculty as well as students. So it is need of today’s medical curriculum.

    Assessment of Incidence and Risk Factors of Dry Socket
    (Ibn Sina Academy of Medieval Medicine & Sciences, 2022-03) Kumar, Sudhir; Goyal, Rohit; Arora, Sanjana; Kusum, Kumari
    Background: Alveolar osteitis (AO) is one of the extractions wound healing disorder. Most authors agree that surgical trauma and difficulty of surgery play a significant role in the development of AO. Hence, under the light of above - mentioned data, the present study was undertaken for assessing the incidence and risk factors of dry socket. Methods: A total of 200 subjects scheduled to undergo dental extraction procedures under local anesthesia were included in the p resent study. Complete demographic and clinical details of all the patients were obtained. All the procedures were carried out under the hands of experienced surgeons. Follow - up was done and incidence of dry socket was recorded. Results: Overall, incidenc e of dry socket in the present study was 17.5 percent. Positive tobacco smoking/chewing habit, Oral contraceptives, Female gender, Existing tooth/gum infection, Past history of dry socket, Traumatic extraction and Mandibular molar extraction were the risk factors in 62.85 %, 34.28 %, 71.42 %, 14.28 %, 25.71 %, 42.85 % and 54.28 % of the patients. Conclusion: Dry socket is a commonly encountered phenomenon and can occur the under the hands of skilled and experienced oral surgeons also. Hence, early recogniti on is necessary.

    Cancer stem cell: A rogue responsible for tumor development and metastasis.
    (2014-07) Kapoor, Aditi; Kumar, Sudhir
    Cancer stem cells are a small population of cells in a tumor. They have the ability to self-renew and maintain the tumor. The most apt and accepted hypothesis for tumor development is Cancer Stem Cells. This review focuses on this concept of cancer stem cells, serving their purpose and leading to the development of tumor. There are many cell biomarkers which have been described for the identification and characterization of cancer stem cells. The most prominent of the cellular markers for the detection of cancer stem cells; CD133, CD44, ALDH-1 along with some others have been discussed in detail in this review.

    Carcinoembryonic antigen (CEA) and other surrogate inflammatory biomarkers in COVID-19
    (CSIR-NIScPR, 2022-06) sharma, Anjali; Maksane, Shalini; Das, Jhuma; Yadav, Dharamveer; Tomo, Sojit; Sharma, Rajeev; Kumar, Sudhir; Cheirmaraj, K; Pai, Vidya; Parab, Kalpana
    It has been two years since the global outbreak of the highly contagious and deadly corona virus disease (COVID-19) caused by SARS-CoV-2 first emerged in China. Since then, various diagnostic, prognostic and treatment strategies undertaken to address the pandemic have been dynamically evolving. Predictive and prognostic role of various biomarkers in COVID-19 has been a subject of intense exploration. We aimed to determine the association of Carcinoembryonic antigen (CEA) and various surrogate inflammatory biomarkers with the severity of COVID-19 disease. This retrospective cohort study was carried out on 98 patients admitted in Jaypee Hospital, Noida with COVID-19 disease. Information regarding demographics, laboratory parameters and clinical history was collected from Hospital Information System. Serum levels of CEA and other biomarkers such as Neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP), Interleukin-6 (IL-6), Ferritin, and Procalcitonin (PCT) were assessed. Correlation analyses were performed between the parameters and acute respiratory distress syndrome (ARDS) stages. Logistic regression and ROC curve analysis were performed to assess the various parameters for distinguishing COVID-19 patients requiring ICU admission. Mean hospital stay, NLR, CEA, IL-6, CRP, Ferritin (P< 0.0001) and PCT (P =0.01) were significantly higher in ICU patients when compared to general ward patients. NLR, median serum CEA, IL-6, and CRP levels were significantly higher in non-survivor compared to the survivors (P< 0.0001, 0.0341 and 0.0092). CEA correlated well with disease severity based upon ARDS classification and was a better marker to differentiate patient according to ARDS stages (ARDS 0 vs 2 P= 0.0006; 0 vs 3 P< 0.0001; ARDS 1 vs 2 P= 0.0183; 1 vs 3 P=0.0006). The area under the Receiver operating characteristic (ROC) curve for CEA was 0.7467 (95% CI- 0.64885- 0.84459) which revealed the potential of CEA as a biomarker to distinguish COVID-19 patients requiring ICU admission. CEA can be used to predict the severity of COVID-19 associated ARDS as well as patients requiring ICU admission. Along with routine inflammatory biomarkers (NLR, CRP, IL-6, PCT, and ferritin), CEA should be used for early identification of critical COVID-19 positive patients and for assessing prognosis.

    Clinical and laboratory features and response to treatment in patients presenting with vitamin B12 deficiency-related neurological syndromes.
    (2005-03-05) Aaron, S; Kumar, Sudhir; Vijayan, J; Jacob, J; Alexander, M; Gnanamuthu, C
    AIMS AND OBJECTIVES: To study the clinical and laboratory features of patients admitted with vitamin B12 deficiency-related (B12def) neurological syndromes. SETTINGS AND DESIGN: A hospital-based retrospective and prospective study conducted at a referral teaching hospital. MATERIALS AND METHODS: Consecutive patients admitted with vitamin B12 deficiency-related neurological disorders during a three-year period from June 2000 to May 2003 were included. Data regarding clinical and laboratory features were obtained. Follow-up was done at least six months following treatment with parenteral vitamin B12. Chi-square test was used for statistical analysis. RESULTS: A total of 63 patients (52 males) with a mean age of 46.2 years were studied. The mean duration of symptoms at presentation was 10.3 months. Myeloneuropathy (54%) was the commonest neurological manifestation, followed by myeloneuropathy with cognitive dysfunction (34%), and peripheral neuropathy (9%). Neuropsychiatric manifestations and dementia were observed in 38% and 19% of patients respectively. All the patients had megaloblastic changes in the bone marrow smear. Eleven (17.5%) patients had both hemoglobin and the mean corpuscular volume (MCV) within the normal range. Follow-up after at least six months of therapy with parenteral B12 showed improvement in 54% patients. CONCLUSIONS: A high index of suspicion of B12def is required in patients presenting with myelopathy, cognitive decline, or neuropathy. A normal hemoglobin or MCV does not exclude B12def; therefore, other tests such as bone marrow smear and serum vitamin B12 assay are essential, as the condition is often reversible with treatment.

    Clozapine-responsive cluster headache.
    (2006-06-29) Datta, Soumitra Shankar; Kumar, Sudhir
    Headaches are commonly associated with various psychiatric disorders. The comorbidity of migraine and psychiatric disorders has been well documented. Here we present a case of schizophrenia with comorbid headache treated with clozapine. The patient's headache fulfilled the diagnostic criteria for cluster headache (CH). To our knowledge this is the first report of CH responding to clozapine therapy. The relationship of headache and psychiatric disorders is a matter of debate and there has been very little research on the aspect of causality or direction of causation. The response of both the conditions to a serotonin-dopamine antagonist such as clozapine might be important in giving newer insights into the pathogenesis of these disorders. It also has the clinical implication of being useful in patients with dual diagnosis.

    Cranial nerve involvement in patients with leprous neuropathy.
    (2006-09-29) Kumar, Sudhir; Alexander, Mathew; Gnanamuthu, Chandran
    BACKGROUND: Leprosy is one of the most common causes of peripheral neuropathy, perhaps closely matched by diabetic neuropathy. Patterns of peripheral neuropathy in leprosy can be varied, which may include mononeuropathy, mononeuritis multiplex and symmetric polyneuropathy. Cranial nerves, especially facial and trigeminal nerves, are also commonly involved in leprosy. AIMS: To find out the pattern and spectrum of cranial nerve involvement in a consecutive series of patients with leprous neuropathy. SETTINGS AND DESIGN: A retrospective review of patients admitted with leprosy to the Neurology Department of a tertiary care center. MATERIALS AND METHODS: All consecutive patients admitted during an 8-year period (1995-2003) and diagnosed to have leprosy were included. They were clinically evaluated to determine the frequency and pattern of cranial nerve involvement. RESULTS: About 18% (9/51) of the leprosy patients seen during that period had clinical evidence of cranial nerve involvement. Facial and trigeminal nerves were the most commonly affected (five and four patients respectively). CONCLUSIONS: Cranial nerve involvement is common in leprosy, which emphasizes the need to carefully examine them. Also, one should exclude leprosy in patients presenting with isolated cranial neuropathies.

    Early recombinant factor VIIa therapy in acute intracerebral hemorrhage: promising approach.
    (2006-03-09) Kumar, Sudhir; Badrinath, H R
    Intracerebral hemorrhage (ICH) is the most devastating form of stroke with a high morbidity and mortality. ICH constitutes about 20-30% of all strokes, with the prevalence being higher in Asian population. Treatment of ICH is predominantly conservative, which includes control of blood pressure, use of anti-cerebral edema measures such as mannitol and mechanical ventilation. The benefit of early surgery in ICH is debatable. Initial hematoma volume and subsequent growth in its size are important predictors of a poor outcome in ICH. This means that therapies aimed at preventing hematoma enlargement in the earliest possible window period could lead to a better outcome in ICH. Recombinant factor VIIa (rFVIIa) is one such agent, which has been shown to prevent hematoma expansion and improve outcome in acute ICH. The purpose of the current review is to focus on the evidence regarding the usefulness of rFVIIa in acute ICH.

    Evaluation of oral health of 6 to 10-year-old asthmatic children receiving bronchodilator through inhaler
    (Indian Society for Dental Research, 2019-09) Kumar, Sudhir; Kalra, Namita; Tyagi, Rishi; Faridi, M M A; Khatri, Amit; Satish, V N V
    Aim: The aim of this study was to evaluate the oral health status in 6 to 10-year-old asthmatic children receiving bronchodilator (salbutamol, salmeterol, etc.) through inhaler and compare them with nonasthmatic healthy children. Settings and Design: The present study was carried out at pediatric and pedodontic department and neighboring government school. It was an observational and case–control study. Statistical Analysis: All data were analyzed using SPSS 20.0 software program and presented as mean ± standard error of mean. Chi-square test was used for the categorical data between groups. Numerical data were analyzed by Mann–Whitney U-test and t-test. Kruskal–Wallis test was performed for comparisons of median value of decayed, missing, filled surface and Decayed, Missing, Filled Surface (dmfs and DMFS) for different variables within asthmatic group. Mann–Whitney U-test for multiple comparisons and P value was adjusted according to Bonferroni correction. Negative binomial analysis was used to calculate adjusted dmfs and DMFS, and univariate analysis of variance was used for adjusted mean plaque and gingival index. Materials and Methods: The study group composed of 70 asthmatic and 70 nonasthmatic children with the same age and social background aged between 6 and 10 years old. Oral health status was assessed using caries, plaque, and gingival index. Dental caries examination was done using the WHO criteria (1997), plaque index by Silness and Loe in 1964 and gingival health by Loe and Silness in 1963. Results: The children in the asthmatic group had significantly higher caries prevalence, severity of dental plaque, and gingivitis compared with the nonasthmatic group. Plaque accumulation and gingivitis increased significantly as severity and duration of asthma increased. Conclusions: Bronchial asthma had an overall deleterious effect on caries prevalence and severity, plaque, and gingivitis on primary and permanent teeth.
