Background: Students have different preferences in the assimilation and processing of information. The VARK learning style model introduced by Fleming includes a questionnaire that identifies a person's sensory modality preference in learning. This model classifies students into four different learning modes; visual (V), aural (A), read/write (R), and kinesthetic (K). Materials and Methods: The 16-point multiple choice VARK questionnaire version 7.1 was distributed to first year undergraduate medical students after obtaining permission for use.Results: Seventy-nine students (86.8%) were multimodal in their learning preference, and 12 students (13.8%) were unimodal. The highest unimodal preference was K-7.7%. Surprisingly, there were no visual unimodal learners. The commonest learning preference was the bimodal category, of which the highest percentage was seen in the AK (33%) and AR (16.5%) category. The most common trimodal preference was ARK (8.9%). The total individual scores in each category were V-371, A-588, R/W-432, and K-581; auditory and kinesthetic being the highest preference. Visual mode had the lowest overall score. There was no significant difference in preference between the sexes. Conclusion: Students possess a wide diversity in learning preferences. This necessitates teachers to effectively deliver according to the needs of the student. Multiple modalities of information presentation are necessary to keep the attention and motivation of our students requiring a shift from the traditional large-group teacher-centric lecture method to an interactive, student-centric multimodal approach.

Background: Reference values of peak expiratory flow (PEF) in Indian adults have to date been derived locally, using an old (Wright) scale peak flow meter. There are thus no reliable reference values for PEF for Indians and this formed the aim of the study. Materials and Methods: A European Union (EU) scale peak flow meter (PFM) was used for the study. A respiratory health and demographic questionnaire was administered to 1000 male and female adults from randomly selected locations in the country in this multi centric study. The locations represented different geographic, ethnic, and socioeconomic backgrounds. Patients were stratified according to height and age. The PEF values were measured using the Breathometer™ (Cipla Ltd., India) with EU scale. Reference equations were derived from multiple regression analysis. Results: A total of 3608 participants were excluded. In 80% of the remaining 6138 healthy adults (M: 3720; F: 2418), the predicted regression equations were derived. Gender, age, and height were the significant determinants of PEF. The equations in L/minute are: Females: PEF = -1.454 (Age) + 2.368 (Height) Males: PEF = -1.807 (Age) + 3.206 (Height). The derived equation was validated by comparing the predicted PEF values with the measured values in the remaining sample of 20% (Mean ΔPEF: M = 1.85 L/minute, CI = -2.76, 6.47; F = 1.64, CI = -2.89, 6.18). An Indian adult with average height and age was found to have approximately 30% lower PEF compared to the corresponding European adult using the Nunn and Gregg equation. Conclusion: We derived reference values of PEF for Indian adults using a validated EU scale peak flow meter.

Media has a complex interrelationship with mental illnesses. This narrative review takes a look at the various ways in which media and mental illnesses interact. Relevant scientific literature and electronic databases were searched, including Pubmed and GoogleScholar, to identify studies, viewpoints and recommendations using keywords related to media and mental illnesses. This review discusses both the positive and the negative portrayals of mental illnesses through the media. The portrayal of mental health professionals and psychiatric treatment is also discussed. The theories explaining the relationship of how media influences the attitudes and behavior are discussed. Media has also been suggested to be a risk factor for the genesis or exacerbation of mental illnesses like eating disorders and substance use disorders. The potential use of media to understand the psychopathology and plight of those with psychiatric disorders is referred to. The manner in which media can be used as a tool for change to reduce the stigma surrounding mental illnesses is explored.

Context: In patients with obesity, intramuscular injections may be deposited subcutaneously due to an increase in gluteal fat. We aimed to use abdominal CT done in our institute for gluteal fat thickness to test our hypothesis. Materials and Methods: After IRB approval, CT scans of the abdomen and pelvis of the past 6 months were analyzed. The thickness of gluteal region subcutaneous fat was measured in a standardized manner. Results: Out of 700 CT scans, studied, 476 were males and 224 were females. The average gluteal fat thickness was 2.34 cm +/- 1 cm. The average fat thickness in males was 1.98 cm +/- 0.98 cm whereas in females was 3.0 cm +/- 1.2 cm. Subcutaneous granulomas were seen in 17 cases and one injection granuloma in the intramuscular plane. Conclusion: A significant number of female patients had increased gluteal fat thickness beyond the reach of routinely used needles. The medications in these patients will thus be unintentionally injected to subcutaneous plane, possibly altering the pharmacokinetics.

Background: The objective of the study was to assess the impact of the mid day meal program by assessing the nutritional status of school students aged 5-15 years receiving midday meals in rural schools and compare them with those in urban schools in Bengaluru, India. Materials and Methods: This cross sectional study involved a sample of 4378 students from government and aided schools. Weight and height were measured and compared with ''means'' and ''percentiles'' of expected standards as endorsed by the Indian Association of Pediatrics. Regression coefficients were also estimated to assess the rate of growth. Results: In all age groups and in both sexes, the observed mean weight and height were below the expected standards. The study findings showed that 13.8% and 13.1% of the studied students were underweight and stunted, respectively (below the third percentile for weight and height for age). A higher proportion of rural students were below the third percentile for both weight and height compared with urban students (weight: 16.3% and 11.5%; height: 17.0% and 10.0%; P < 0.05 for both weight and height). Only 2.4% and 3.1% were above 97 ^th percentile for weight and height. The rate of growth of height for weight showed a declining trend with increasing age in all the groups. Discussion: The authors believe that the magnitude of the burden of undernourished students as seen in this study would have been much greater in the absence of the midday meal program. Conclusion: Greater involvement of the private sector to assist the government would help augment nutrition in children and indirectly impact school performance, attendance and literacy.

Background: Surveying vulnerable and incarcerated populations is often challenging. Newer methods to reach and collect sensitive information in a safe, secure, and valid manner can go a long way in addressing this unmet need. Homosexual men in India live with inadequate social support, marginalization, and lack legal recognition. These make them less reachable by public health agencies, and make them more likely to continue with high-risk behaviors, and contract human immunodeficiency virus (HIV). Aims: To understand coping skills and HIV testing patterns of homosexual men versus heterosexual men. Materials and Methods: An internet based study using a secure web platform and an anonymised questionnaire. The brief COPE Inventory was used to assess coping styles. Results: A total of 124 respondents were studied. Homosexual men used negative coping skills such as behavioral disengagement and tested for HIV significantly more often than heterosexual men. Heterosexual respondents used positive coping skills more often. The most commonly used coping skill by heterosexual men was instrumental coping and by homosexual men was acceptance. Discussion: Overall, homosexual men used negative coping mechanisms, like behavioral disengagement more often. The Indian family structure and social support is probably responsible for heterosexual men's over-reliance on instrumental coping, while resulting in disengagement in homosexuals. Conclusion: The lack of legal and social recognition of homosexuality has negatively impacted lives of gay men in India. This is strongly linked to harmful psychological and public health implications for HIV prevention and mental health for homosexual men.

Background: The outcome of sepsis is significantly affected by early institution of goal-directed therapies and hence, the search for an early marker of sepsis continues. Aims and Objectives: To observe microalbuminuria levels between patients with sepsis and those without sepsis s admitted to the medical intensive care unit (MICU) of a tertiary referral centre (primary) as also to assess the change in microalbuminuria levels in the first 24 hours as a predictor of mortality and morbidity relative to the APACHE II and SOFA scores. Materials and Methods: This was a prospective observational study where 125 patients with sepsis and 38 without were assessed. Trend of microalbuminuria was assessed from the change of ACR value within 6 hours of admission (ACR1) to the ACR value at 24 hours (ACR2) in both groups of patients. Results and Conclusion: Significantly higher levels of microalbuminuria were found among patients with sepsis as compared to those without sepsis. The levels decreased in survivors with sepsis after 24 hours, whereas they continued to remain almost at the same levels among those without sepsis. The change in microalbuminuria levels over 24 hours can be used to measure the effectiveness of therapy. Persistence of high levels or increasing trend of microalbuminuria levels over 24 hours was found to be a predictor of a poor outcome. A high level of microalbuminuria at 24 hours and increasing trend of microalbuminuria also predicted mortality better than APACHE II and SOFA scores.

Background: In traumatic acute subdural hematoma (aSDH) management, systemic anticoagulation is contraindicated, particularly during the first 2 weeks. We present two cases of patients with nonoperative aSDH whose stroke risk led to heparinization within 2 weeks of the initial hemorrhage and examine their outcomes to illustrate the risks and benefits associated with systemic anticoagulation. Materials and Methods: Two elderly males, on warfarin at baseline who developed traumatic nonoperative aSDH were heparinized within 2 weeks of aSDH onset. Results: One patient showed a decreased SDH volume on Day 19. The second patient developed sudden onset headache with fixed/dilated pupils on Day 5. In this patient, a CT scan of the brain revealed marked enlargement of the aSDH from 0.9 to 2.4 cm with midline shift of 1.5 cm, and uncal herniation that was incompatible with life. Conclusion: Heparinization within two weeks of aSDH may cause SDH enlargement resulting in rapidly fatal neurologic deterioration. Further study is needed to more definitively address this issue.

Background: This study aimed to assess correlation between measures of hypoglycemia and glycemic control in patients with type 2 diabetes mellitus (T2DM) treated with sulfonylureas. Materials and Methods: T2DM patients being initiated on a sulfonylurea (SU) on background of a failing oral antihyperglycemic regimen were followed up for 12 weeks. (HbA1c) was measured at baseline and end of follow-up. Hypoglycemia was assessed using Stanford Hypoglycemia Questionnaire at week 12. Results: Of the total 1069 patients enrolled, 950 were considered evaluable. A weak negative correlation was observed between end of follow-up HbA1c values and hypoglycemia score, using both linear regression analysis (correlation coefficient -0.12; P = 0.0002) and negative binomial regression (β slope -0.09; P = 0.0010). A similar correlation was also observed between change in HbA1c from baseline and hypoglycemia score (β slope -0.07; P = 0.0048). Mean HbA1c reduction was lowest (0.65 ± 2.27%) in patients not reporting any hypoglycemia and highest (1.28 ± 2.40%) in patients with hypoglycemia score greater than median of 2 (P = 0.0031). There was no correlation between hypoglycemia frequency and end of follow-up HbA1c values (P = 0.4111). Conclusion: With addition of SU on a background of a failing oral anti-hyperglycemic regimen, the extent of glycemic control correlates directly with measures of patient reported hypoglycemia.

Background/Aims: The aim of this study was to assess whether changes in Cystatin C (CyC) after 48 h post contrast media exposure was a reliable indicator of acute kidney injury and the validity of a risk scoring tool for contrast-induced acute kidney injury (CI-AKI). Materials and Methods: We enrolled 121 patients for whom diagnostic coronary angiography were planned. The risk score for CI-AKI was calculated and serum creatinine (sCr) and CyC were measured before and 48 h post coronary angiography. CyC and sCr based AKI was calculated as a 25% increase from baseline within 48 h from contrast media exposure. Results: Mean serum CyC and creatinine concentrations were 0.88 ± 0.27 mg/dL and 0.79 ± 0.22 mg/dL, respectively before the procedure and 1.07 ± 0.47 mg/dL and 0.89 ± 0.36 mg/dL, respectively 48 h after contrast media exposure (P < 0.001). CyC based AKI occured in 45 patients (37.19 %) and sCr based AKI occured in 20 patients (16.52%) after the procedure. Mean risk score was found to be 4.00 ± 3.478 and 3.60 ± 4.122 for CyC based AKI and sCr based AKI, respectively and was significantly increased in CyC based AKI group (P < 0.001). Conclusions: CyC measured 48 h after contrast media exposure may be a more sensitive indicator of CI-AKI relative to creatinine and Mehran risk scoring is in good correlation with CyC increase.

Background: IL-6, IL1-β, TNF-α and IL-21 have been identified in the growth, progression and dissemination of multiple myeloma. To dte, there is no published data about serum levels of IL-21 in patients with multiple myeloma. In the present study we have investigated circulating levels of cytokines, such as IL-6, IL-1β, TNF-α, IL-21 and the association of these levels with the disease stage in newly diagnosed multiple myeloma patients. Materials and Methods: Twenty healthy controls and 44 newly diagnosed multiple myeloma patients were evaluated. Patients were classified according to Durie-Salmon criteria, international staging system (ISS) and bone disease. Quantification of cytokine levels in serum were performed by using ELISA. Results: The levels of cytokines in patients' serum are found elevated than healthy controls. However, only the serum levels of IL-1β and TNF-α were found statistically significant. TNF-α levels of patients with ISS stage 3 were significantly higher than patients with ISS stage 1 and 2 (P 0.000). IL-1β was significantly elevated in advanced stage patients (stage II-III) (P 0.040). There was no correlation between IL-1β, TNF-α, IL-21 levels and bone lesions. IL-6 levels were significantly elevated who have at least three visible lytic bone lesions and/or bone fracture in comparison to patients who have one or two visible or no visible lytic bone lesions (P 0.048). Conclusion: It appears that there is no association of serum IL-21 level with multiple myeloma in contrast to the other cytokines such as IL-6, IL-1β, TNF-α.

Purpura fulminans (PF) is associated with several infections, most notably with meningococcus, staphylococcus, and streptococcus infections. However, there are few reports of association of this entity with spotted fever from India. We report the case of a 55-year-old man who presented with fever, headache, and myalgia. On the seventh day of fever he developed nonblanching purple hemorrhagic purpura on the trunk and most prominently on the extremities consistent with purpura fulminans. Immunofluorescent assay confirmed the diagnosis of spotted fever. PF though common with rocky mountain spotted fever (RMSF) is rarely seen in association with Indian tick typhus, the usual cause of spotted fever in India.

Medical simulation has come a long way in Western health care; however, in developing world, health education sectors have not adequately addressed its significance and role in preparing and updating heath care personnel. Validification, standardization, paucity of trainers, deficiency of a structured syllabus, and cost of equipments need to be overcome in the next decade. Despite these problems, worldwide acceptance of the concept of medical simulation is growing. It is undoubtedly the wave of future. Multidisciplinary, interprofessional, and multimodal simulation training is possible. Virtual worlds are increasing the vistas of training, making the actual health care dispensing more skilled and safe.

The presence of ectopic splenic tissue in the scrotum is attributed to splenogonadal fusion, a rare congenital anomaly. This ectopic splenic tissue can be an incidental finding or less often present as a scrotal mass later in adult life. Given the rarity of splenogonadal fusion, especially in the adult population, this case highlights the clinical characteristics of the condition, with a special focus on the signs and findings that might help prevent unnecessary orchiectomy.

Peritoneal tuberculosis is an uncommon complication of peritoneal dialysis in Europe. It is more common in Asian immigrants. A delayed diagnosis is frequent and impairs patient outcomes. We present two cases of peritoneal tuberculosis with common features that may help suspect the disease early countries with a low incidence. Both patients were females (of Spanish origin) who had recently restarted peritoneal dialysis following kidney transplantation. Both developed bacterial peritonitis clinically that was refractory to conventional antibiotics, despite clearance of bacteria. Both stopped calcium-containing phosphate binders because of increasing serum calcium that in one case led to frank hypercalcemia that persisted despite low calcium dialysate. Peritoneal biopsy was the first positive test in both cases. This report emphasizes the recent return from transplantation and rising serum calcium levels as features that should alert the physician of a potential underlying tuberculous peritonitis.

Dabigatran-absorption is dependent on the intestinal P-glycoprotein (P-gp)-system, and P-gp activity is modulated by several drugs. We report an 83-old female with atrial fibrillation who developed gastrointestinal bleeding. She was under a therapy with non-steroidal anti-inflammatory drugs (NSAID) and P-gp-modulating drugs and renal function was impaired. We conclude that NSAID and P-gp-modulating drugs should be avoided in dabigatran-treated patients. If renal function deteriorates the dabigatran-dosage should be reduced or the therapy should be stopped. There is an urgent need to increase knowledge about drug interactions with dabigatran.
