ABSTRACT
Background: Renal tumors constitute approximately 3% of all malignancies in adults. They form a heterogenous group with variable morphological, immunohistochemical, and molecular features. Aim: The objective of this study was to analyze the spectrum of adult renal tumors at a tertiary care center and study the demographic and histomorphological features. Materials and Methods: In this study, 55/87 nephrectomy specimens resected for adult renal tumors during a 1-year period were analyzed retrospectively. Results: There were 4 benign (7.2%) and 51 (92.7%) malignant tumors. There was a male preponderance with a male: female ratio of 3.42:1. The tumors were seen to occur equally in both kidneys. The most common tumor was clear cell renal cell carcinoma (RCC), the conventional type accounting for 65.5% of our study group. There were one each of multilocular cystic renal neoplasm of low malignant potential, papillary RCC, chromophobe RCC, Mit family RCC, oncocytoma and angiomyolipoma and two clear cell papillary RCC during this 1-year period. Uncommon tumors included neuroendocrine carcinoma (1), epithelioid angiomyolipoma (1), mixed epithelial stromal tumor (1), Ewings sarcoma (2), and glomangioma (1). Five cases of urothelial carcinoma of renal pelvis/ureter also were present. Conclusion: This article gives an overview of the spectrum of adult renal tumors at a tertiary care center with an in-depth literature review providing recent advances in each category of tumors.
ABSTRACT
Background: In recent times internet addiction has become a leading cause of many personality and psychiatric disorders. Researches done on this field has shown that younger population is more vulner-able because of their psychosocial and environmental characteristics. The medical profession is also joining this parade. Objectives: 1) To assess pattern of Internet Addiction among medical students. 2) To estimate the prev-alence of Anxiety, Depression and Stress among medical students. 3) To determine the correlation be-tween Internet Addiction and its impact on mental health. Methods: Cross-sectional study was conducted among 308 undergraduate students of 1st and 2nd year MBBS in a medical college, Bangalore. Young’s Internet Addiction Test –20 was used for assessment of Internet Addiction and DASS-21questionnaire for the assessment of Depression, anxiety and stress. Spearman’s Rank Correlation was used to find the strength of association. Results: In the present study mean age of the study participants was 20.6 years, around 54% were using internet from age of >15 years. Overall prevalence of severe internet addiction was found to be 1.3%. Nearly 53% reported depression and 69% had a state of anxiety.Conclusion: Chronic usage of internet including in odd hours was observed. Study showed strong posi-tive correlation between Depression and Internet addiction and Stress and Internet addiction.
ABSTRACT
Introduction: Sepsis has a death rate of ?25% globally and its clinical treatment presents an important clinical challenge. The rapid progression of sepsis requires correspondingly swift adjustments in therapy, and accurate identification of disease severity is therefore vitally important for predicting prognosis, treatment, preventing complications, reducing complication and mortality. With this background, the present research is aimed to study the relation of serum procalcitonin levels in cases with sepsis, to calculate APACHE II scores and to correlate the levels of serum PCT levels with APACHE II Score with the outcome. Methodology: This was a prospective observational non interventional cohort study was conducted in the Clinic of Intensive Care unit of a tertiary care hospital and medical college in western India from May 2020 to December 2020. Results: A total of 75 patients, admitted to the ICU with the diagnosis of sepsis, were included in this prospective observational study. Of them 47 (62.7%) were males and highest cases were aged between 60 to 69 years. Of the total 75 patients, 47 (62.7%) patients were survivors. Age, gender and involvement of system were not associated with mortality while lower APACHE II score and presence of co-morbidities were significantly associated with mortality. Conclusion: From this study we conclude that the lower APCHE II score and presence of co-morbidity significantly increases the mortality in ICU patients admitted with sepsis
ABSTRACT
AIMS: Small group teaching in Pharmacology offers an effective platform to encourage interaction amongst peers and self-directed learning. The present study is an attempt to assess and compare the effectiveness and perception of students on two different pedagogical methods: Crossword puzzles and Student Led Objective Tutorials (SLOT). METHODS: Second year undergraduate students who gave their informed consent were divided randomly into two groups: one which received crossword puzzle as a teaching learning method and the other had SLOT during which the students conducted an interactive quiz with multiple choice questions prepared by themselves. The students' perceptions were recorded using a self-administered questionnaire. One week later, a unit test was conducted for both the groups and the performance of the students was compared. Statistical analysis was done using independent Student's T test with SPSS version 15.0. RESULTS: Analyses revealed a statistical significant difference (P<0.001) between the mean marks obtained in the SLOT group (n= 74; 6.5±3.8) and the marks obtained in the crossword group (n= 87; 4.2±2.9), with the students in the tutorial group performing better. The students opined that SLOT sessions helped them to understand Pharmacology better whereas crossword sessions enabled them to memorize the names of the drugs. CONCLUSION: The present study revealed that SLOT sessions fared better compared to the crossword puzzles in terms of improving the students' test scores. It fostered teamwork, self-directed learning skills and critical thinking. Crossword puzzles make the session more student friendly as it is fun and engaging but a careful design is inevitable as it may fail to test in-depth learning in students.
OBJETIVOS: O ensino de farmacologia em pequenos grupos oferece uma plataforma eficaz para estimular a interação entre pares e a aprendizagem autodirigida. O presente estudo procurou avaliar e comparar a eficácia e percepção dos alunos em dois métodos pedagógicos diferentes: palavras cruzadas e tutoriais objetivos conduzido pelo aluno (SLOT). MÉTODOS: Alunos do segundo ano de graduação, que deram seu consentimento informado, foram divididos aleatoriamente em dois grupos: um que recebeu palavras cruzadas como método de ensino-aprendizagem e o outro teve SLOT onde os alunos realizaram um questionário interativo com questões de múltipla escolha elaborado por si mesmos. As percepções dos alunos foram registradas por meio de um questionário autoaplicável. Uma semana depois, um teste foi realizado para ambos os grupos e o desempenho dos alunos foi comparado. A análise estatística foi feita usando o teste T de student de amostras independentes. RESULTADOS: As análises revelaram uma diferença estatisticamente significativa (P <0,001) entre as notas médias obtidas no grupo SLOT (n = 74; 6,5±3,8) e as notas obtidas no grupo de palavras cruzadas (n = 87; 4,2±2,9), com os alunos do grupo tutorial tendo melhor desempenho. Os alunos opinaram que as sessões de tutoria objetiva conduzida pelos alunos os ajudaram a entender melhor a Farmacologia, ao passo que as sessões de palavras cruzadas lhes permitiram memorizar os nomes dos medicamentos. CONCLUSÃO: O presente estudo revelou que as sessões do SLOT se saíram melhor comparativamente àquelas com as palavras cruzadas em termos de melhorar as pontuações dos alunos nos testes, assim como promoveu o trabalho em equipe, habilidades de aprendizagem autodirigida e pensamento crítico. As palavras cruzadas tornam a sessão mais amigável ao aluno, pois é divertida e envolvente, mas um design cuidadoso é inevitável, pois pode falhar em testar o aprendizado em profundidade nos alunos.

Background: Poor sanitation and hygiene are known to be associated with increased morbidity and mortality. Despite all the global efforts 68% population still lacks the basic sanitation facilities. The internal migrant population is a vulnerable group that even lags behind the general population in basic sanitation. This study was aimed to assess sanitation practices among the internal migrant population.Methods: This community based cross sectional study was conducted in a rural village of north-west Delhi from June 2019 to November 2019. People migrated from other parts of the country and residing in the study area for minimum last six months, were included in the study. Data were collected using pre-tested, semi-structured, interviewer-administered study tool, and analysed using SPSS 20.0 software.Results: Two hundred eleven respondents were included in the study. About 88% were using latrine for defecation, out of this 57% were using household sanitary latrines, rest were using community latrines. About 12% were still practicing open defecation. Among those who were using latrine, only about 60% were found regular users. Positive health associated with latrine usage, comfort, privacy, security, presence of latrine in the rented house, quality construction and availability of water were the major motivators and enablers to regular usage of latrine.Conclusions:The internal migrant population is a vulnerable group, with suboptimal sanitation practices. Along with information education communication and behaviour change communication activities, policymakers need to pay special attention to this group in order to achieve global and national sanitation targets.

The sensitivity of RMI2 is 86.74%, specificity is 81.25%, positive predictive value is 96%, negative predictive value is 54.16%, percentage of false negative is 13.25% and percentage of false positive is 18.75%.Conclusions: The efficiency of RMI was definitely better than indivisual parameters and efficiency of RMI 1 and RMI2 are similar.
ABSTRACT
AIMS: To determine the learning approach of second-year undergraduate medical students and whether a surface or deep approach to learning had any correlation with the pharmacology sessional and university examination marks obtained. METHODS: A cross-sectional study was conducted among second-year medical students in their fifth semester. To determine the students' learning approach, whether superficial or deep, we used the Revised Two Factor Study Process Questionnaire (R-SPQ-2F), which contains 20 items in the form of a five-point Likert scale and is suitable for use in higher education settings. Cronbach's alpha was calculated using the scores obtained from a sample of 20 students to determine the internal consistency. To determine the relationship between the learning approach and examination scores, the average of the individual sessional examination marks and the university examination scores obtained by the students were calculated. RESULTS: Of the 170 students who participated in the study, 87 (51.2%) were females. The Cronbach's alpha value was considered acceptable for both surface and deep approach. While the academic performance was significantly better in females (U=2571.5; p=0.001), no difference was seen in the learning approach based on gender. Fifty (29.4%) students had a higher score for the surface approach. This group had lower examination scores compared with those with equal scores for surface and deep approach or higher scores for the deep approach. A weak negative correlation was seen between the examination marks and surface approach (τb=-0.167; p=0.002). When analyzed based on gender, the correlation was statistically significant only in females (τb=-0.173; p=0.02). CONCLUSIONS: A weak negative correlation was seen between the examination marks and surface approach to learning. Although statistically significant, the actual difference between the groups was of a small magnitude. Hence, whether promoting deep learning approach improves academic performance in terms of marks obtained in the examination needs to be confirmed by further studies.
OBJETIVOS: Investigar a abordagem de aprendizagem de estudantes de medicina do segundo ano de graduação e se uma abordagem superficial ou profunda teve alguma correlação com as notas obtidas na disciplina de farmacologia e nos exames universitários. MÉTODOS: Um estudo transversal foi conduzido entre estudantes do segundo ano de medicina em seu quinto semestre. Para determinar a abordagem de aprendizagem dos alunos, como superficial ou profunda, usamos o questionário Revised Two Factor Study Process Questionnaire (R-SPQ-2F), que contém 20 itens em forma de uma escala Likert de cinco pontos, sendo o seu uso adequado para ambientes de ensino superior. O alfa de Cronbach foi calculado usando as pontuações obtidas de uma amostra de 20 alunos para determinar a consistência interna. Para determinar a relação entre a abordagem de aprendizagem e as pontuações do exame, calculou-se a média das notas dos exames individuais e as pontuações dos exames universitários obtidas pelos alunos. RESULTADOS: Dos 170 alunos que participaram do estudo, 87 (51,2%) eram do gênero feminino. O alpha de Cronbach foi considerado bom tanto para a abordagem superficial quanto profunda. Enquanto o desempenho acadêmico foi significativamente melhor em mulheres (U=2571,5; p=0,001), nenhuma diferença baseada no gênero foi observada na abordagem de aprendizagem. Cinquenta (29,4%) estudantes tiveram uma pontuação mais alta para a abordagem superficial. Esse grupo teve escores de exame mais baixos em comparação com aqueles com escores iguais para abordagem superficial e profunda ou escores mais altos para a abordagem profunda. Uma fraca correlação negativa foi observada entre as notas do exame e a abordagem superficial (τb=-0,167; p=0,002). Quando analisada com base no gênero, encontrou-se uma correlação de magnitude fraca e negativa apenas no gênero feminino (τb=-0,173; p=0,02). CONCLUSÕES: Uma fraca correlação negativa foi observada entre as notas do exame e a abordagem superficial para a aprendizagem. Embora estatisticamente significativa, a diferença real entre os grupos foi de pequena magnitude. Portanto, se a promoção de uma abordagem de aprendizagem profunda melhora o desempenho acadêmico em termos de notas obtidas no exame, isso precisa ser confirmado por outros estudos.

Background: Post Void Residual Urine (PVR) is a key marker for the evaluation of the efficacy of bladder emptying particularly in women with pelvic organ prolapse and lower urinary tract dysfunction. Objectives of the present study were to compare pre and postoperative post void residual urine volume and to know the relation of PVR to urinary symptoms and prolapse. Methods: 65 patients admitted with urogenital prolapse. Detailed history, general physical examination was done as per predesigned and pretested proforma. Grading for prolapse was done by POP-Q, Baden walker halfway. PVR was measured before and after operation Results: Age has shown significant relation with the raised PVR > 50 ml (p=0.007). Out of 65 cases, 11 had second, 48 had third degree and 6 had procedentia according to Baden Walker system. Urge and stress incontinence were complained by 43% and 26% of patients respectively and increased frequency and nocturia was complained by 68% and 65% of patients. Storage symptoms were not significantly associated with degree of prolapse or raised PVR. Straining to void, incomplete emptying and has to reduce to void were present in 42, 46 and 47 patients respectively and showed significant association with degree of prolapse. Except incomplete emptying other two were associated with raised PVR. Conclusion: Vaginal hysterectomy with anterior colporrhaphy was effective procedure in reducing elevated PVR in prolapse patients.
ABSTRACT
Background & objectives: Osteoarthritis (OA) is a degenerative disease characterized by joint pain and progressive loss of articular cartilage. Entada pursaetha has been traditionally used in the treatment of inflammatory disease, liver ailment, etc. In this study we investigated suppressive effect of ethanolic extract of E. pursaetha (EPE) on monosodium iodoacetate (MIA)-induced osteoarthritis pain and disease progression by histopathological changes in joints in a rat model. Methods: OA was induced in right knee of rat by intra-articular injection of 3 mg of MIA and characterized by pathological progression of disease and pain of affected joint. Spontaneous movements, mechanical, thermal and cold sensitivity were monitored at days 0 (before drug and MIA injection), 7, 14 and 21 of MIA administration. EPE (30, 100 and 300 mg/kg), vehicle or etoricoxib (10 mg/ kg; reference drug) were administered daily for 21 days by oral route. Results: EPE at various doses significantly reduced mechanical, heat, cold hyperalgesia and increased the horizontal and vertical movements in intra-articular MIA injected rats. EPE prevented the damage to cartilage structure and reduced the cellular abnormalities. Articular cartilage of rats treated with EPE at 300 mg/kg group was almost normal with well-developed smooth surface and chondrocytes were distributed individually or arranged in column. Interpretation & conclusions: the present findings showed that the EPE was not only able to mitigate pain and hyperalgesia but also inhibited MIA-induced cartilage degeneration in vivo. EPE may have the potential to become therapeutic modality in the treatment of osteoarthritis. However, further studies need to be done to confirm these findings in other models and clinical trials.
ABSTRACT
Background & objectives: Psoriasis is a chronic, recurrent skin disorder, with a poorly understood pathogenesis. Studies at molecular/genetic levels continue to explore various biomolecules as potential markers of the disease. In the present study, we sought to evaluate the possible roles of ferritin and iron in psoriasis. Methods: Patients with psoriasis (n=81) and healthy controls (n=45) were included. Patients were graded as mild, moderate and severe based on the Psoriasis Area Severity Index (PASI). Serum ferritin and iron levels were measured by electro chemiluminescence and inductively coupled plasma - atomic emission spectrometry (ICP-AES), respectively. Results: The ferritin levels in psoriasis patients were not significantly different from that of controls. There was no significant difference in ferritin concentrations between psoriasis groups of severity. Fe was found to be significantly reduced (P<0.05) in the psoriasis patients when compared to controls. The ferritin to Fe ratio was significantly higher (P<0.05) in the psoriasis groups when compared to the control group. Interpretation & conclusions: Our results indicate a possible role of ferritin and iron in psoriasis. Further studies with large samples need to be done to confirm findings.
