Abstract
BACKGROUND Direct to physician advertisements and direct to consumer advertisement (DTCA) is a well-known marketing strategy of pharmaceutical companies. Studies from the West and also from the Indian sub-continent revealed several lacunae in such advertisements. OBJECTIVES The present study was carried out to understand the international and national scenario regarding the lacunae in drug advertisements and the opinion of both physicians and patients regarding DTCA. METHODS The present study was conducted after obtaining approval from the institutional ethics committee. Warning letters (WLs) issued to pharmaceutical companies by United States Food and Drug Administration (USFDA) and Therapeutic Goods Administration (TGA) due to discrepancies in the advertisements were analyzed for reasons that were grouped into one of the following categories: overstatement of efficacy; unapproved indication; lack of adequate directions to use; omission of adverse effects; misleading claims; advertisement made for an unapproved drug (investigational new product). Drug advertisements in Current Index of Medical Specialties (CIMS) April-July 2014 issue was also analyzed for lacunae depending on categories as mentioned above. Physicians and patients in a tertiary care medical college and hospital were administered a validated questionnaire exploring their views about crucial aspects of DTCA. Descriptive statistics was used for each of the categories. RESULTS A total of 93 WLs issued by USFDA and 36 by TGA were assessed. Majority of the WLs by USFDA were issued for omission of adverse effects (61/93, 65.6%) followed by misleading claims (54/93, 58.1%). Similarly, WLs by TGA were also mainly issued for the presence of misleading claims (35/36, 97.2%) followed by overstatement of efficacy (26/36, 72.2%) and CIMS evaluation had revealed that 78/92 (84.8%) advertisements omitted adverse effects, 20/92 (21.7%) had misleading claims, 9/92 (9.8%) had unapproved indications and 7/92 (7.6%) overstated the efficacy. With regard to the opinion regarding DTCA, 69.9% physicians had a patient discussing DTCA that was clinically inappropriate. One hundred (64.5%) out of 155 physicians opined that DTCA encourage patients to attend physicians regarding preventive healthcare. On the contrary, 82/155 (52.9%) physicians felt that DTCA would damage the same. Similarly, 69 out of the total 100 patients felt that drug advertisements aid them to have better discussions with their treating physicians. Surprisingly, a large majority (91/100) were of the opinion that only safe drugs are allowed to be advertised. CONCLUSION To conclude, from the findings of this study both the physicians and patients should be cautious and not overzealous while dealing with drug advertisements or promotional literature. More stringent scrutiny and issue of WLs or blacklisting of indulging pharmaceutical companies are mandatory by the regulatory agency to contain the same.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (M. tuberculosis), is the leading infectious disease which claims one human life every 15-20s globally. The persistence of this deadly disease in human population can be attributed to the ability of the bacterium to stay in latent form. M. tuberculosis possesses a plethora of mechanisms not only to survive latently under harsh conditions inside the host but also modulate the host immune cells in its favour. Various M. tuberculosis gene families have also been described to play a role in this process. Recently, human bone marrow derived mesenchymal stem cells (MSCs) have been reported as a niche for dormant M. tuberculosis. MSCs possess abilities to alter the host immune response. The bacterium finds this self-renewal and immune privileged nature of MSCs very favourable not only to modulate the host immune system, with some help from its own genes, but also to avoid the external drug pressure. We suggest that the MSCs not only provide a resting place for M. tuberculosis but could also, by virtue of their intrinsic ability to disseminate in the body, explain the genesis of extra-pulmonary TB. A similar exploitation of stem cells by other bacterial pathogens is a distinct possibility. It may be likely that other intracellular bacterial pathogens adopt this strategy to 'piggy-back' on to ovarian stem cells to ensure vertical transmission and successful propagation to the next generation.

Abstract
AIM The aim of this randomized controlled, double-blind trial was to comparatively evaluate the anaesthetic efficacy and injection pain of 1.8 mL of 2% lidocaine with different concentrations of epinephrine (1 : 80 000 and 1 : 200 000) in patients with symptomatic irreversible pulpitis. METHODOLOGY Sixty-two adult volunteers, actively experiencing pain, were randomly allocated into 2 groups and received 1.8 mL of 2% lidocaine with either 1 : 80 000 or 1 : 200 000 epinephrine concentration. Endodontic access preparation was initiated 15 min after the initial IANB. Pain during treatment was recorded using the Heft-Parker visual analogue scale (HP VAS). The primary outcome measure, and the definition of 'success', was the ability to undertake pulp access and canal instrumentation with no or mild pain (HP VAS score <55 mm). Secondary outcome measure was the pain experienced during LA solution deposition. Statistical analysis was performed using Mann-Whitney U-test and chi-square test. RESULTS The anaesthetic success rates of 2% lidocaine solutions containing 1 : 80 000 and 1 : 200 000 epinephrine concentrations were 20% and 28%, respectively. The difference was not statistically significant. There was also no significant difference in the pain experienced during deposition of the solutions. CONCLUSIONS Two percent lidocaine solution used for IANB achieved similar success rates when used with 1 : 80 000 or 1 : 200 000 epinephrine concentration.

Abstract
Tuberculosis, caused by Mycobacterium tuberculosis, remains a leading infectious disease taking one human life every 15 s globally. The two well-characterized strains H37Rv and H37Ra, derived from the same parental strain M. tuberculosis H37, show dramatically different pathogenic phenotypes. PE/PPE gene family, comprising of 176 open reading frames and present exclusively in genus Mycobacterium, accounts for ∼10% of the M. tuberculosis genome. Our comprehensive in silico analyses of PE/PPE family of H37Ra and virulent H37Rv strains revealed genetic differences between these strains in terms of several single nucleotide variations and InDels and these manifested in changes in physico-chemical properties, phosphorylation sites, and protein: protein interacting domains of the corresponding proteomes. Similar comparisons using the 13 sigma factor genes, 36 members of the mammalian cell entry family, 13 mycobacterial membrane protein large family members and 11 two-component signal transduction systems along with 5 orphaned response regulators and 2 orphaned sensor kinases failed to reveal very significant difference between H37Rv and H37Ra, reinforcing the importance of PE/PPE genes. Many of these changes between H37Rv and H37Ra can be correlated to differences in pathogenesis and virulence of the two strains.

Abstract
Our aim was (i) to investigate the hypothalamo-hypophyseal-gonadal axis in hyperthyroid Indian males, (ii) to rule out the modulatory role of adrenal steroids on it and (iii) to determine if the simultaneous rise in oestradiol and luteinising hormone (LH) in hyperthyroid males is due to a positive feedback action of oestradiol on pituitary LH release. Age- and BMI-matched men were divided into two groups, I, euthyroid subjects (n = 17) and II, hyperthyroid patients (n = 12) on the basis of their thyroid hormone levels. Serum levels of thyroid-stimulating hormone, triiodothyronine, thyroxine, LH, follicle-stimulating hormone (FSH), prolactin, E(2), T, P(4), sex hormone binding globulin and dehydroepiandrosterone sulphate (DHEAS) were assayed. Mean levels of T and E(2) were approximately two times higher in group II in comparison with group I. DHEAS levels were similar in both groups ruling out any adrenal involvement. Mean serum LH level was 2.6 folds higher in group II in comparison with group I. Mean serum levels of FSH were higher in group II, it was marginally nonsignificant. On the basis of these and previous observations, we hypothesise that endocrinological dimorphism in human male and female is not rigid; a sustained rise in serum oestradiol probably induces a positive feedback action on pituitary leading to elevated gonadotrophin levels.

Abstract
End-stage kidney disease (ESKD) patients on maintenance hemodialysis (MHD) have a lot of anxiety. Anxiety and coping are associated with the locus of control; the present investigation aimed to study the state and trait anxiety, locus of control, and active and passive coping among patients on MHD. Thirty MHD patients and 30 controls were administered State-Trait Anxiety Inventory, Rotter's Locus of Control Scale, and Coping Responses Inventory. There were significantly higher scores on state and trait anxiety, respectively (67.53 ± 10.89 vs. 59.40 ± 6.97, P < 0.01, and 62.97 ± 8.45 vs. 58.07 ± 7.06, P < 0.05), and locus of control (11.27 ± 3.55 vs. 9.04 ± 1.86, P < 0.01) in patients as compared to controls. On coping responses, patients and controls differed on positive reappraisal (54.33 ± 4.67 vs. 51.17 ± 3.12, P < 0.01), seeking guidance and support (58.07 ± 5.51 vs. 53.27 ± 4.22, P < 0.01), problem solving (51.03 ± 4.70 vs. 47.57 ± 4.73, P < 0.01), cognitive avoidance (60.27 ± 6.76 vs. 56.80 ± 4.08, P < 0.05), acceptance or resignation (61.67 ± 6.30 vs. 58.83 ± 4.23, P < 0.01), emotional discharge (68.07 ± 6.78 vs. 64.30 ± 4.50, P < 0.05), approach coping (205.57 ± 10.55 vs. 189.70 ± 11.37, P < 0.01), and avoidance coping (255.30 ± 16.45 vs. 241.10 ± 10.50, P < 0.01). A higher prevalence of anxiety trait could be the cause of anxiety in MHD patients besides the medical problems. The locus of control among patients though a mixed one was significantly more toward externalism. Thus, there is a need to identify this group well in advance and prepared not only medically but also psychologically for MHD.

Abstract
9609 Background: Patients undergoing treatment for cancer often report problems with their cognitive function (CF), which is an essential component in maintaining Quality of Life (QoL). We conducted a longitudinal study of lung cancer (LC) patients to systematically evaluate changes in QOL including changes in CF, over time. Methods: Between 2005–2008, we followed 1757 primary LC patients who responded to CF questions at least once within 8 years of diagnosis. Overall QoL measured by LCSS and LASA (scores 0–100 from worst to best) were assessed among 1,604 of 1,757 (91%) who completed the questionnaire at one or both of two time periods: short-term (T1-within 3 years of diagnosis) and long-term follow-up (T2-beyond 5 years of diagnosis). Questions rated overall CF and problems in thinking clearly. Results: The median age at the time of LC diagnosis was 68 years in men (n=834) and 65 years in women (n=770), p<0.0001. At T1, the mean score of patients reporting problems with CF was 63.2 (±22.45) vs 74.4 (±20.38) who reported no problems (p<0.0001). At T2, the mean score was 62.2 (±24.18) for patients who reported CF problems and 78.1 (±18.28) who reported no changes with their CF (p<0.0001). At T1, the mean score of patients reporting problems thinking clearly was 66.1 (±21.65) vs 75.6 (±20.21) reporting no problems with their thinking (p<0.0001). At T2, the mean score was 70.4 (±20.95) for patients reporting problems thinking clearly vs 82.6 (±17.76) who reported no problems (p<0.0001). Conclusions: Self-reported QoL of lung cancer survivors showed substantial deficits with their cognitive function. Prospective and objective assessments are needed to determine if cancer treatments are positively associated with cognitive decline, to identify the patients at risk, and to test appropriate interventions.

Abstract
e19566 Background: We retrospectively analysed records of the Patients visiting the pathology department of Sir Ganga Ram Hospital, New Delhi a super-speciality hospital, between February 2007- February 2008. Out of a total of 16,500 cases, NHL was reported in 154 (0.93%)cases. The median age was 52 yrs and the no. of male patients were 104 and female were 50 making M:F = 2:1. The type of NHL was B-Cell type (CD-20+ve) in 132(85%) and T-Cell type (CD 3+ve) in 22 (15%) cases. Out of 154 patients, 77 were nodal and 77 were extra nodal. Additional features - HIV positivity in 2 patients, autoimmune haemolytic disease in 1 patient and thalessemia major in 1 patient. In extra-nodal group of NHL patients the no. Of male and female patients were 55 & 22 respectively (M:F=2.5:1). Out of 77 extra-nodal cases, 31(20%) were GIT NHL (Stomach -16, Colon-8, Ileum-4, and Duodenum-3) and out of the rest 46 extra-nodal cases the site of origin was - head & neck-14, skin n soft tissues -8, primary CNS-6, testicular-4, para-spinal- 3, breast mass-3, perinephric-2, bones-2 and 1 each in cervix, lung mass, liver and cervical plexus. Methods: A detailed analysis of 31 GIT NHL cases was carried out. 28 out of 31 were B-Cell type and 3 were T-Cell type. 26 out of 31 were diffuse large cell variety, 2 were mixed small & large cell variety and 1 MALT variety. In 2 patients the type of lymphoma could not be ascertained. Bone marrow infiltration was present in 2 out of 31 cases of GIT Lymphoma. Surgery was carried out in 15 of 31 GIT NHL cases and these were arising from Colon, Ileum and Duodenum. No surgery was performed in patients with stomach lymphoma. Results: Of all the extra-nodal cases chemotherapy was given to 39 patients - R-CHOP = 20 patients, CHOP = 13 patients, high dose MTX in primary CNS NHL = 6 patients. CR was achieved 16 out of 20 R-CHOP patients (80%), 8 out of 13 CHOP Patients (61 %) and 4 out of 6 high dose MTX patients (66%). No significant financial relationships to disclose.

Abstract
The mesophasic microreservoir comprises lyotrophic liquid crystals. The liquid crystals were prepared of Brij-35, cetosteryl alcohol and propranolol and evaluated for parameters viz. anisotropy, size and size distribution and drug entrapment efficiency. Subsequent to this liquid crystals based transdermal drug delivery system (TDS) was prepared by incorporating liquid crystals in previously prepared matrix based transdermal patch and evaluated for stability studies like temperature, humidity and aging. The system was also studied for tensile strength, moisture content, water vapor transmission, drug content, anisotropy and In vitro drug release studies.

Abstract
9004 Background: Patients receiving treatment for cancer can experience a diminution of their cognitive abilities which can persist for many years after. The present study examined the potential of modafinil as a cognitive enhancer on memory and attention in a randomized clinical trial in breast cancer patients following completion of treatment. Methods: Breast cancer patients who reported a score of = 2 on the Brief Fatigue Inventory (BFI) an average of 22.8 months following completion of chemotherapy were enrolled. In Phase 1, patients received 200mg modafinil open-label once daily for 4 weeks. In Phase 2, patients with a positive response following Phase 1 were randomized either to an additional 4 weeks of modafinil or to placebo. Tests of memory and attention selected from the Cognitive Drug Research (CDR) computerized cognitive assessment were performed at baseline (before modafinil) and after completing Phase 1 and 2. The difference between scores at baseline and scores at Phase 1 and Phase 2, were subjected to a Wilcoxon's signed rank test. Results: Of the 82 women enrolled, 68 completed all 3 CDR assessments in the study (range=33–83 years, median age=54 years). At the end of Phase 1 (week 4), modafinil had a significant effect on the Speed of Memory Index (p=0.0047) and the Digit Vigilance Test (p=0.0014) but showed no significant effect on Quality of Working Memory (p=0.3528) nor on Power of Attention (p=0.8953). At the end of phase 2 (week 8), the group that continued modafinil demonstrated improved Mean Continuity of Attention (p=0.0002) compared with the placebo group and also demonstrated significantly greater improvements in Quality of Episodic Secondary Memory relative to placebo (p<0.005). This improvement was observed at week 4, and was maintained throughout the study. Finally, continued modafinil demonstrated significantly greater improvement in Speed of Memory relative to placebo (p=0.009). Conclusions: Modafinil provides significant improvements in attention and speed of memory for breast cancer patients following their treatment of cancer. Although further study is needed, these findings suggest that modafinil may enhance quality of life in this patient population.
