Abstract
A 35-year-old, HIV-seropositive male (CD4 count 41 cells/mm3) on highly active antiretroviral ( HAART) presented with fever and weight loss for 3 months and new skin lesions. He was earlier diagnosed of TB and was on anti-tubercular therapy (ATT). The retroperitoneal lymph node aspirate showed acid-fast bacilli and epithelioid cell granulomas; however, cultures remained sterile. A dual infection with Mycobacterium tuberculosis and Mycobacterium avium was diagnosed with multiplex polymerase chain reaction (MPCR). Clarithromycin was added to ATT, and on follow-up at 1 and 3 months, the patient responded well. Molecular methods like MPCR should be exploited for routine diagnosis of high-risk patients.

Abstract
BACKGROUND We sought to determine whether the substantial benefits of topical nitroglycerin with first-line, platinum-based, doublet chemotherapy in advanced nonsmall-cell lung cancer (NSCLC) seen in a phase II trial could be corroborated in a rigorous, multicenter, phase III trial. PATIENTS AND METHODS Patients starting one of five, prespecified, platinum-based doublets as first-line chemotherapy for advanced NSCLC were randomly allocated treatment with or without nitroglycerin 25 mg patches for 2 days before, the day of, and 2 days after, each chemotherapy infusion. Progression-free survival (PFS) was the primary end point. RESULTS Accrual was stopped after the first interim analysis of 270 events. Chemotherapy was predominantly with carboplatin and gemcitabine (79%) or carboplatin and paclitaxel (18%). The final analysis included 345 events in 372 participants with a median follow-up of 33 months. Topical nitroglycerin had no demonstrable effect on PFS [median 5.0 versus 4.8 months, hazard ratio (HR) = 1.07, 95% confidence interval (CI) 0.86-1.32, P = 0.55], overall survival (median 11.0 versus 10.3 months, HR = 0.99, 95% CI 0.79-1.24, P = 0.94), or objective tumor response (31% versus 30%, relative risk = 1.03, 95% CI 0.82-1.29, P = 0.81). Headache, hypotension, syncope, diarrhea, dizziness, and anorexia were more frequent in those allocated nitroglycerin. CONCLUSION The addition of topical nitroglycerin to carboplatin-based, doublet chemotherapy in NSCLC had no demonstrable benefit and should not be used or pursued further. CLINICAL TRIALS NUMBER Australian New Zealand Clinical Trials Registry Number ACTRN12608000588392.

Abstract
Passive autocatalytic recombiner (PAR) is one of the most suitable devices for mitigation of hydrogen, generated in nuclear power plant under accidental conditions. For this purpose we report development of stainless steel wire gauze supported Pt-Ru nanoparticles as catalysts. Simultaneous electroless deposition has been employed for the synthesis of the catalysts. Pt-Ru based bimetallic catalysts were characterized for their rate of coating kinetics, noble metal loading, phase purity by XRD and surface morphology by SEM, TEM and elemental analysis by SIMS. Developed catalysts were found to be active for efficient recombination of hydrogen and oxygen in air as well as in presence of various prospective poisons like CO2, CH4, CO and relative humidity. Pt-Ru based bimetallic catalyst with 0.9% loading was found to be active for CO poisoning up to 400 ppm of CO.

Abstract
Basal cell carcinoma (BCC) is a common malignancy with a good prognosis in the majority of cases. However, some BCC patients develop a more advanced disease that poses significant management challenges. Such cases include locally advanced, recurrent or metastatic BCC, or tumours that occur in anatomical sites where surgical treatment would result in significant deformity. Until recently, treatment options for these patients have been limited, but increased understanding of the molecular basis of BCC has enabled potential therapies, such as hedgehog signalling pathway inhibitors, to be developed. A clear definition of advanced BCC as a distinct disease entity and formal management guidelines have not previously been published, presumably because of the rarity, heterogeneity and lack of treatment options available for the disease. Here we provide a UK perspective from a multidisciplinary group of experts involved in the treatment of complex cases of BCC, addressing the key challenges associated with the perceived definition and management of the disease. With new treatments on the horizon, we further propose a definition for advanced BCC that may be used as a guide for healthcare professionals involved in disease diagnosis and management.

Abstract
Sequestrated meningocoele is an uncommon developmental anomaly in which meningothelial elements are found in the skin or subcutaneous tissue without underlying bony defect. By contrast, naevus sebaceous of Jadassohn (NSJ) is a circumscribed hamartomatous lesion occurring in about 0.3% of newborns. We report a child with a histologically confirmed sequestrated meningocoele within an NSJ on his scalp vertex. Such an occurrence has not been reported previously.

Abstract
We report an unusual north Indian patient with Hemoglobin Evanston [alpha 14 (A12) Try --> Arg] who had acquired cyclic thrombocytopenia (10-1230 x 10(9)/l periodic oscillation of four week duration) which recovered without any specific therapy. She later developed Takayasu's disease and underwent three corrective stents. She is presently in clinical remission and is on regular follow up. To the best of our knowledge our patient is the first report of Hb Evanston from the indigenous population of India and highlights the need to look for point mutations in the alpha globin gene, which may interact with thalassemia or other hemoglobinopathies, in atypical cases. The association of these three disorders in our patient is possibly unrelated though an immune basis for the cyclic thrombocytopenia and Takayasu's disease is likely as seen in this report.
