Abstract
Background The European organization Research and Treatment of Cancer Quality of Life Questionnaire-Oesophagogastric 25 (EORTC QLQ-OG 25) is designed for patients with esophagogastric cancer. Its performance has never been tested with benign disorders. A health-related quality-of-life questionnaire does not exist for patients with benign corrosive-induced esophageal strictures. Hence, we evaluated the EORTC QLQ-OG 25 in Indian patients with corrosive strictures. Methods The English or Hindi version of QLQ-OG 25 was administered to 31 adult patients undergoing outpatient esophageal dilation at GB Pant hospital, New Delhi. These patients had refractory or recurrent esophageal strictures due to corrosive ingestion and had not undergone reconstructive surgery. Score distribution was analyzed, and item performance was determined based on floor and ceiling effects. Convergent validity, discriminant validity, and internal consistency were checked. Results The average time to finish the questionnaire was 6.70 minutes. Most scales fulfilled convergent validity (corrected item-total correlation >0.4), barring the Odynophagia scale and one item of the Dysphagia scale. Most scales exhibited divergent validity except for odynophagia and one item of dysphagia. Cronbach's alpha was >0.70 for all scales except odynophagia. Responses to questions evaluating taste, cough, swallowing saliva, and talking were highly skewed and had prominent floor effects. Overall, the questionnaire demonstrated good internal consistency, convergent validity, and divergent validity in benign corrosive-induced refractory esophageal strictures patients. Conclusion The EORTC QLQ-OG 25 can be satisfactorily used in patients with benign esophageal strictures to assess health-related quality of life.

Abstract
Adult onset Still’s disease (AOSD), a multi-systemic inflammatory disorder, is a rare disorder but an important differential to be considered in patients of Pyrexia of Unknown Origin, especially if patient presents with polyarthritis. Macrophage activation syndrome (MAS), a subset of Secondary Hemophagocytic Lymphohistiocytosis (HLH), considered as the most life threatening complication of AOSD, mostly develops around the onset of disease. Hence, in a previously undiagnosed case of AOSD, recognizing MAS as a presenting feature complicating underlying AOSD is essential for increased patient survival, as in our case.
A 39 year old diabetic female presented with high grade fever with chills and multiple joint pains symmetrically involving proximal shoulder, knees and distal joints (involving MCP, PIP and DIP joints of hand) associated with swelling and early morning stiffness, relieved on activity, since past 6 months. No history of oral ulcers, rash, jaundice, weight loss, loss of appetite, foreign travel or close animal contact.
On examination, Pallor was present, Blood Pressure was 120/70 mm Hg, pulse rate was 102/min and temperature was 100 F. On per abdomen, mild hepatomegaly was present and other system examination was unremarkable.
Routine laboratory findings on day of presentation have been summarised (Table 1.1). Ultrasound Abdomen revealed hepatomegaly and Chest X-ray showed signs of old infective foci. Peripheral smear for Malarial parasite, Ns1Ag and dengue serology, Widal test and Montoux test were negative. Blood cultures and urine cultures were sterile. X-Ray of joints were normal. USG of B/L Knee joints showed mild joint effusion bilaterally with no internal echoes (non tappable). Trans-thoracic echo and Trans-esophageal echo were normal. CT chest, neck and abdomen showed old tubercular changes in lung. Tests for atypical bacterial infections which was normal (RK 39, Chickungunya, Brucella, Leptospirosis and Scrub typhus). Fever did not respond to Broad Spectrum Antibiotics, Antimalarials or Antitubercular therapy and patient continued to have persistent fever spikes.
Autoimmune profile showed ANA and RA Factor negative but markers of inflammation were raised: CRP- 521, ESR -148, IL-6 – 84.0, Procalcitonin-6.9 and S.Ferritin >2000. During the work up for Anemia, Microcytic hypochromic anemia was found with Elevated NAP SCORE-165. Incidentally, her triglycerides were found to be elevated (356) and a reduced fibrinogen. With these results, we planned for a bone marrow aspirate and biopsy which showed increased myeloid preponderance (32:1), increased histiocytes and evidence of hemophagocytosis.
The 2004 diagnostic criteria of HLH was fulfilled. After ruling out almost all infectious and malignant causes of secondary HLH, we searched for a rheumatologic cause. Thus diagnosis of AOSD (after fulfilling Yamaguchi’s criteria) with MAS (a subset of 2’ HLH) was made. Patient had dramatic improvement after receiving steroids with her fever episodes and joint pains settling completely thereafter.
Prompt recognition of life threatening complications like MAS which pose diagnostic difficulty due to overlapping features in a patient of AOSD, should be done at the earliest to improve patient prognosis and survival. Serum Ferritin levels can be considered a useful marker to assess the disease activity and to predict MAS occurrence in such patients.

Abstract
A transcriptome analysis reveals the transcripts and alleles differentially expressed in sugarcane genotypes with contrasting lignin composition. Sugarcane bagasse is a highly abundant resource that may be used as a feedstock for the production of biofuels and bioproducts in order to meet increasing demands for renewable replacements for fossil carbon. However, lignin imparts rigidity to the cell wall that impedes the efficient breakdown of the biomass into fermentable sugars. Altering the ratio of the lignin units, syringyl (S) and guaiacyl (G), which comprise the native lignin polymer in sugarcane, may facilitate the processing of bagasse. This study aimed to identify genes and markers associated with S/G ratio in order to accelerate the development of sugarcane bioenergy varieties with modified lignin composition. The transcriptome sequences of 12 sugarcane genotypes that contrasted for S/G ratio were compared and there were 2019 transcripts identified as differentially expressed (DE) between the high and low S/G ratio groups. These included transcripts encoding possible monolignol biosynthetic pathway enzymes, transporters, dirigent proteins and transcriptional and post-translational regulators. Furthermore, the frequencies of single nucleotide polymorphisms (SNPs) were compared between the low and high S/G ratio groups to identify specific alleles expressed with the phenotype. There were 2063 SNP loci across 787 unique transcripts that showed group-specific expression. Overall, the DE transcripts and SNP alleles identified in this study may be valuable for breeding sugarcane varieties with altered S/G ratio that may provide desirable bioenergy traits.

Abstract
OBJECTIVES The treatment response in chronic pulmonary aspergillosis (CPA) is usually assessed based on the improvement in clinical and imaging findings. Herein, we evaluate serum Aspergillus fumigatus-specific IgG, serum galactomannan, weight change, and lung function for assessing treatment response in subjects with CPA. METHODS We categorized treatment response as favourable (improved or stable clinical response with radiologically improved or stable disease) or unfavourable (worsening of symptoms or radiological progression) after 6 months of treatment with antifungal azoles. We measured A. fumigatus-specific IgG, serum galactomannan, weight, and lung function at baseline, 3 months, and 6 months in those with favourable and unfavourable treatment response. RESULTS One hundred and twenty-six consecutive treatment-naïve subjects (53.2% (67/126) males; mean ± SD age, 42.3 ± 14.7 years) with CPA were included. One hundred and six and 20 were classified as having favourable and unfavourable response, respectively. After 6 months of treatment, the decline in serum A. fumigatus-specific IgG (n = 119) was similar in those with favourable or unfavourable response (mean ± SD, -26.3 ± 45.5 mgA/L vs. -3.4 ± 65.6 mgA/L; p 0.20). There was no significant change in the serum galactomannan (favourable vs. unfavourable: mean ± SD, -0.11 ± 2.8 vs. -0.62 ± 2; p 0.92) or FEV1 (favourable vs. unfavourable: mean ± SD, 24 ± 250 mL vs. -62 ± 154 mL; p 0.19) after 6 months of treatment. There was significant loss of weight (mean ± SD, -2.5 ± 4.5 kg) in subjects with unfavourable response. CONCLUSION Serum A. fumigatus-specific IgG and serum galactomannan inconsistently decrease following treatment and may not be useful indicators for monitoring treatment response in CPA. Similarly, there is little change in pulmonary function following treatment. A gain in body weight is seen in those with favourable response.

Abstract
Levodopa, a prodrug of dopamine, is the first line drug in the treatment of Parkinson's disease. All current levodopa products are formulated in combination with aromatic amino acid decarboxylase inhibitors such as carbidopa or benserazide to prevent the peripheral metabolism of levodopa. The objective of the present investigation was to produce floating microspheres of carbidopa (CD)/levodopa (LD) to enhance their efficacy by increasing their gastric residence time, which is major technique to improve efficacy of narrow absorption window drugs. The microspheres were prepared by the o/w emulsion-solvent diffusion method using polymers hydroxypropylmethyl cellulose K15 M (HPMC K15 M) and ethyl cellulose (EC). The effects of various formulation and process variables on the particle size, in vitro floating behavior, percent drug entrapment, and in vitro drug release were studied. The size and surface morphology of prepared microspheres were characterized by optical and scanning electron microscopy, respectively. In vitro drug release studies were performed and drug release kinetics was evaluated using the linear regression analysis. The prepared microspheres exhibited prolonged drug release (approximately 10h) and remained buoyant for >12 h. Spherical and smooth-surfaced microspheres with encapsulation efficiency ranging from 43% to 80% were obtained. In vitro studies demonstrated diffusion-controlled drug release from the microspheres.
