Abstract
OBJECTIVE To assess the knowledge, attitude and practices regarding tuberculosis (TB) and DOTS among young medical graduates (interns). DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Lady Hardinge Medical College and Maulana Azad Medical College, New Delhi, India, during November and December 2002, simultaneously. SUBJECTS AND METHODS A pre-tested semi-structured questionnaire consisting of 30 items was administered to the young medical graduates/interns posted in different departments. The questions covered mode of transmission, symptoms of pulmonary TB, investigations, short course chemotherapy including DOTS as well as conventional anti-tubercular treatment, special situations, health education and chemoprophylaxis. RESULTS A total of 287 interns were surveyed. Majority of the study subjects (92.7%) ranked DOTS strategy as more successful for treating tuberculosis in comparison to self-administered therapy. However, a mere 4.2% study subjects were aware of all modes of transmission. One hundred and eighty-nine (65.9%) correctly chose sputum examination for acid fast bacilli as the single most confirmatory test for diagnosing pulmonary TB. The rest either gave incorrect responses (including ELISA-17.0%, PCR-9.8%, X-ray chest-4.2%, ESR-1.7%) or did not respond (1.4%). Only 2.1% marked pyrazinamide and rifampicin as the agents to be avoided in patients with liver disease. One hundred and forty-one different treatment regimens were mentioned in the responses received and of those only 11(7.8%) were scientifically acceptable. CONCLUSION TB is a major health problem in South-East Asian countries. There is a need for appropriate changes to be made in the undergraduate medical teaching/training curriculum in the concerned countries with regard to TB.

Abstract
We developed a novel indirect sandwich immuno-polymerase chain reaction (I-PCR) assay for the detection of mycobacterial antigen 85B (Ag85B, 30kDa, Rv1886c) in pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) patients. The amino-modified reporter DNA was covalently attached with the antidetection antibody through a heterobifunctional cross-linking agent succinimidyl 4-[N-maleimidomethyl]-cyclohexane-1-carboxylate. The detection limit of Ag85B by I-PCR was found to be 1 femtogram (fg)/mL, which was 10(6)-fold lower than an analogous enzyme-linked immunosorbent assay (ELISA). The sensitivities of 85% and 77% with I-PCR and 77.6% and 62.5% with ELISA were observed in smear-positive and smear-negative PTB patients, respectively, with high specificity. On the other hand, sensitivities of 84% and 63.7% with I-PCR and 68% and 47.5% with ELISA were observed in confirmed and clinically suspected EPTB cases, respectively, with high specificity.

Abstract
Genital Chlamydia trachomatis infection creates a substantial reproductive health burden in women. The high incidence of asymptomatic infection often precludes timely antibiotic therapy to control the sequelae of infection, and therefore a vaccine is required. Dendritic cells (DC) are now being used as an adjuvant for vaccine development; however, the fate of C. trachomatis in human DC and differential regulation of cytokine secretion remains unclear. Hence, an in vitro study was performed using C. trachomatis (serovar D) elementary body (EB)-pulsed, monocytederived DCs co-cultured with autologous CD4+ T cells. Secreted cytokines were measured to assess the protective/pathogenic immune response. The effect of (beta-oestradiol in the modulation of DC function and on Toll-like receptor (TLR) gene expression was also studied. Elementary body-pulsed DCs showed induction of protective Th1 immune response with upregulation of TLR4 expression, secretion of interleukin (IL)-6, IL-12 and interferon (IFN)-y, together with upregulation of major histocompatibility complex (MHC) class II, CD83 and CD86. When co-cultured with autologous CD4+T cells, DCs presented chlamydial antigens efficiently, as shown by proliferation of T cells and secretion of IL-2 and IFN gamma, which provide a protective immune response. However; pretreatment of cells with oestradiol significantly reduced TLR4 expression and upregulated IL-10 secretion, modulating the Th1 immune response to a Th2-type response, which may lead to pathogenesis.

Abstract
The aim of the present research is to develop economic, fast, and versatile method for the removal of toxic organic pollutant phenol from wastewater using eggshell. The batch experiments are conducted to evaluate the effect of pH, phenol concentration, dosage of adsorbent, and contact time on the removal of phenol. The paper includes in-depth kinetic studies of the ongoing adsorption process. Attempts have also been made to verify Langmuir and Freundlich adsorption isotherms. The morphology and characteristics of eggshell have also been studied using scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and X-ray fluorescence analysis. At ambient temperature, the maximum adsorption of phenol onto eggshells has been achieved at pH 9 and the contact time, 90 min. The experimental data give best-fitted straight lines for pseudo-first-order as well as pseudo-second-order kinetic models. Furthermore, the adsorption process verifies Freundlich and Langmuir adsorption isotherms, and on the basis of mathematical expressions of these models, various necessary adsorption constants have been calculated. Using adsorption data, various thermodynamic parameters like change in enthalpy (∆H(0)), change in entropy (∆S(0)), and change in free energy ∆G(0) have also been evaluated. Results clearly reveal that the solid waste material eggshell acts as an effective adsorbent for the removal of phenol from aqueous solutions.

Abstract
Serine/threonine kinase IKBKE is a newly identified oncogene; however, its regulation remains elusive. Here, we provide evidence that IKBKE is a downstream target of signal transducer and activator of transcription 3 (STAT3) and that tobacco components induce IKBKE expression through STAT3. Ectopic expression of constitutively active STAT3 increased IKBKE mRNA and protein levels, whereas inhibition of STAT3 reduced IKBKE expression. Furthermore, expression levels of IKBKE are significantly associated with STAT3 activation and tobacco use history in non-small cell lung cancer (NSCLC) patients examined. In addition, we show induction of IKBKE by two components of cigarette smoke, nicotine and nicotine-derived nitrosamine ketone (NNK). Upon exposure to nicotine or NNK, cells express high levels of IKBKE protein and mRNA, which are largely abrogated by inhibition of STAT3. Characterization of the IKBKE promoter revealed two STAT3-response elements. The IKBKE promoter directly bound to STAT3 and responded to nicotine and NNK stimulation. Notably, enforcing expression of IKBKE induces chemoresistance, whereas knockdown of IKBKE not only sensitizes NSCLC cells to chemotherapy but also abrogates STAT3- and nicotine-induced cell survival. These data indicate for the first time that IKBKE is a direct target of STAT3 and is induced by tobacco carcinogens through STAT3 pathway. In addition, our study also suggests that IKBKE is an important therapeutic target and could have a pivotal role in tobacco-associated lung carcinogenesis.

Abstract
Hypertension is one of the leading causes to develop chronic kidney disease (CKD) and could be a risk factor for progression of CKD to end stage renal disease (ESRD).Uncontrolled hypertension worsens CKD. Hypertension control may contribute to prevent CKD in early stages and retards the progression of CKD stages to ESRD. Prevalence of CKD in people with diagnosed and chronic hypertension is known to be high, but little is known about the prevalence of CKD in those with newly diagnosed Hypertension. Present work was undertaken to see the prevalence of CKD among people with newly diagnosed hypertension. In this cross-sectional study, we accessed the CKD in newly diagnosed hypertensive patients and determined the association between hypertension and CKD. CKD was defined as either kidney dysfunction or kidney damage or both as per National Kidney Foundation Guidelines. 106 of newly diagnosed patients and 106 of normotensive controls were recruited in the study. 51.9% of newly diagnosed hypertensive patients and 23.6% of normotensive controls had CKD which was statistically significant (p-value <0.001). Difference in the mean value in eGFR and spot urine ACR (mg/mmol) between hypertensive patients and normotensive controls was statistically significant (p-Value <0.001). Both systolic BP and diastolic BP negative significantly correlated with eGFR (p-Value < 0.001 and 0.024 respectively) and positive significantly correlated with ACR (p-Value 0.003 and 0.003 respectively). The prevalence of CKD is high among people with newly diagnosed hypertension. Those, people might benefit from interventions aimed at preventing development and/or progression of both CKD and hypertension.

Abstract
Abstract
Background
Skin incisions have traditionally been made using a scalpel. Cutting diathermy, a more recent alternative, is thought to increase the risk of infection, impair healing and decrease cosmesis. Recent studies suggest otherwise, claiming that diathermy may offer potential advantages with respect to blood loss, incision time and postoperative pain. The aim of this meta-analysis was to compare skin incisions made by either scalpel or cutting diathermy.
Methods
A systematic literature search and review was performed for studies published from January 1980 until June 2011. Randomized clinical trials comparing scalpel and cutting diathermy for skin incisions of any operation were included. Primary outcomes included wound complication rate, blood loss, incision times and pain scores.
Results
Fourteen randomized trials met the criteria for inclusion in the meta-analysis, providing outcome data for a total of 2541 patients (1267 undergoing skin incision by cutting diathermy and 1274 by scalpel). The median length of follow-up across all studies was 6 weeks (range 4 days to 19 months). Compared with a scalpel incision, cutting diathermy resulted in significantly less blood loss (mean difference 0·72 ml/cm2; P < 0·001) and shorter incision times (mean difference 36 s; P < 0·001), with no differences in the wound complication rate (odds ratio 0·87; P = 0·29) or pain score at 24 h (mean difference 0·89; P = 0·05).
Conclusion
Skin incisions made by cutting diathermy are quicker and associated with less blood loss than those made by scalpel, and there are no differences in the rate of wound complications or postoperative pain.

Abstract
The incidence of tuberculosis (TB) is increasing worldwide and so are its consequences. Its oral manifestations are infrequent, occurring in approximately 3% of all cases. Although the primary lesion occurs as a pulmonary infection, the extrapulmonary infections have also shown an increase over the past few years. These infections generally involve the head and neck through haematogenous or lymphatic routes. The clinical presentation may be as an ulcer, granuloma, orofacial TB, TB of the salivary glands or tuberculous lymphadenitis. Rarely, secondary oral manifestations associated with pulmonary infection are seen, which can appear as lesions on the gingiva, palate, lips, tongue, buccal mucosa, frenulum and in the jaw bones. Owing to the rarity of orofacial TB, it seldom arouses clinical suspicion, especially when a positive history of a systemic infection or therapy is denied. Tuberculous involvement of the mandibular condyle is even rarer, and only two such cases are reported so far, both in English-language literature. Further, the diagnosis of such a case is extremely difficult as there are no specific signs pathogonomic of infection. The only manifestation may be a localized painful swelling of the jaw. The presented case is of osteomyelitis of the mandibular condyle in a 20-year-old male patient in whom TB was later suspected. In this case report the role of diagnostic techniques is emphasized as the osteomyelitis of the condyle has the risk of being easily missed owing to its atypical signs and symptoms and atypical radiographic appearance.

Abstract
Metaplastic carcinoma breast is rare entity with incidence of 0.02% of all breast malignancies. The ranges of age at diagnosis as well as clinical symptoms do not differ from that of conventional invasive ductal breast cancer. We are reporting a rare case diagnosed as metaplastic breast carcinoma on ultrasonography and confirmed histopathologically. The case merits presentation because of its rarity, low frequency of axillary metastasis and difficulty in interpreting the morphological features which correspond with prognosis.
