Abstract
A 2-month-old male with surgically resected sacral chordoma presented with multiple hypopigmented macules showing characteristic patchy, sharply demarcated areas of pigment network on dermoscopy. These dermoscopic findings were suggestive of the ash-leaf macules of tuberous sclerosis over other common hypopigmented macules in neonates. Chordomas presenting in early childhood in the sacral location have been reported as a rare manifestation of tuberous sclerosis complex. The combination of these findings led to a diagnosis of tuberous sclerosis, confirmed with the finding of a heterozygous TSC2 gene deletion; treatment with sirolimus resulted in regression of cardiac rhabdomyomas and hypopigmented macules.

Abstract
BACKGROUND Many patients with asthma use their inhalers incorrectly, which can lead to sub-optimal asthma control and an increased risk of exacerbations. The Accuhaler/Diskus and Turbuhaler are arguably two of the most commonly used dry powder inhalers worldwide. METHODS A systematic literature review (SLR) was conducted to assess the impact of inhalation errors with these dry powder inhalers on clinical outcomes in asthma. Database searches were conducted in MEDLINE, Embase and proceedings from scientific conferences. Observational studies in adults and adolescents with asthma, reporting data for Accuhaler/Diskus and Turbuhaler devices and at least one outcome of interest, were included. Dual-independent screening and validation of studies was performed. RESULTS The search identified 35 studies. A range of inhaler errors was observed across studies and devices. In 8 out of the 9 studies that involved the two devices, the percentage of overall inhaler error rates was numerically (7 studies) or significantly (1 study) higher for Turbuhaler than Diskus, ranging from 3.7% to 71.9% for Diskus and 1.2%-83% for Turbuhaler. Critical errors, reported in three studies using similar definitions, ranged from 20% to 43% for Diskus and 32%-100% for Turbuhaler. Five studies reported a significant association between inhaler errors and worse asthma control, while one showed no difference. CONCLUSIONS This SLR identified a large range of inhaler errors with both devices. Across devices, a better inhalation technique was associated with better asthma outcomes. This systematic review confirms the importance of patients using their inhalers correctly as an integral part of achieving optimal asthma outcomes.

Abstract
OBJECTIVE To document morbidities in adolescents with cystic fibrosis (CF) from India. METHODS Details of children with cystic fibrosis surviving beyond 15 years of age were extracted from hospital records, and analyzed. RESULTS 43 children [Median (IQR) age 18.7 (17, 20.6) years, were enrolled. Median (IQR) body mass index was 15.82 (13.5, 19.05) kg/m2. Pseudomonas species were isolated from respiratory specimens of 34 (79%) adolescents. Allergic bronchopulmonary aspergillosis (ABPA) and Cystic fibrosis-related diabetes (CFRD) were seen in 12 (28%) and 11 (26%) patients, respectively. Conjugated hyperbilirubinemia and distal intestinal obstruction syndrome (DIOS) were diagnosed in 15 (35%) and 6 (14%) children, respectively. Pseudomonas species colonization (P=0.04) and multiple pulmonary exacerbations in last one year (P<0.001) were significant predictors of FEV1% predicted. CONCLUSION Malnutrition, chronic airway colonization, ABPA, CFRD, conjugated hyper-bilirubinemia and DIOS are morbidities observed in adolescents with CF in India. The data support the need for early screening of CF-associated morbidities.

Abstract
Penttinen type of premature aging syndrome is an extremely rare progeroid disorder, caused by activating variants in the receptor tyrosine kinase domain of the PDGFRB gene. Only eight individuals have been previously reported worldwide, with a consistent phenotype of prematurely aged appearance, lipoatrophy, hypertrophic skin lesions, proptosis, malar hypoplasia, and marked acro-osteolysis. We report the first patient of Penttinen syndrome from India, with novel radiographic findings of terminal phalangeal tufting, thereby expanding the phenotypic spectrum of Penttinen syndrome.

Abstract
Childhood obesity is an important public health issue worldwide. Urbanization, sedentary lifestyle and change in food habits are the chief reasons behind this pandemic. In a small proportion of children, obesity is the result of endocrine, syndromic or monogenic causes. The present paper summarizes the methods, definitions and cut-offs for identification of obesity in children. We have briefly reviewed the various techniques used for estimation of body fat in children and the cut-offs for defining obesity based on body fat percentage, and the reference curves based on body mass index and waist circumference. The etiology of obesity in children, including individual behaviors, macro- and micro-environmental influences, and endocrine causes have been discussed, and an approach to etiological assessment of obese children has been presented. Special emphasis has been laid on clinical pointers that suggest the presence of syndromic, endocrine or monogenic forms of obesity, such as, short stature, dysmorphism, neurocognitive impairment and early age at onset.

Abstract
BACKGROUND Imatinib mesylate is able to at least modify the course of gastrointestinal stromal tumours (GISTs). Neoadjuvant use for locally advanced lesions is evolving as a new treatment paradigm in this hitherto universally fatal disease. METHODS AND RESULTS The study patients with locally advanced GIST received neoadjuvant and adjuvant imatinib mesylate. Response was noted as per the RECIST protocol and overall progression free survival was reported. Of 19 patients (mean age 38.5 years, range 26 yrs to 64 yrs) studied, 13 achieved partial response (PR) and 6 a stationary disease (SD) on preoperative imatinib. Histopathological evaluation and grading of responses revealed only moderate and low grade pathological response after imatinib. R0 resection was possible in 13/19 and R1 in 6/19. Imatinib was well tolerated and adverse reactions were minimal. Post operative complications of surgery were not out of the ordinary for a surgical series featuring extensive abdominal surgery. CONCLUSION Preoperative imatinib in locally advanced GIST seems to be a reasonable option for locally advanced GIST patients and enough downstaging to allow a resection with microscopically negative margins can be expected in a fairly good proportion of patients.

Abstract
Pulmonary disease due to talc, a group of hydrous magnesium silicates, is almost exclusively encountered secondary to occupational exposure or intravenous drug abuse. Talcosis or talc pneumoconiosis is one of the rarer forms of silicate-induced lung disease. It is seen in workers exposed during its production, and occasionally, in users of cosmetic talc and in intravenous drug addicts. Very often, the history of exposure is not recognised by the patient, and it is only the finding of granulomatous cellular interstitial lesions containing birefringent crystals which indicates considerable talc exposure. We report a 38-year-old woman who was initially diagnosed with sarcoidosis, until a bronchoscopic biopsy revealed the presence of numerous foreign body giant cells and birefringent particles forming non-caseating granulomas. There was no history of occupational exposure to talc or intravenous drug abuse. The patient responded to oral corticosteroid treatment. Talcosis is generally considered to be relatively benign.

Abstract
OBJECTIVE To determine the effectiveness of influenza vaccination on acute respiratory illness (ARI) and on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) during a 2-year study conducted prior to and after influenza vaccination in patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS Eighty-seven male patients with COPD were stratified on the basis of their forced expiratory volume in 1 s (FEV(1)) as having mild, moderate and severe COPD. These patients were evaluated for a total duration of 2 years; 1 year prior to vaccination and for a period of 1 year following influenza vaccination. The vaccine (split virion, inactivated) composed of A/New Caledonia/20/99 (H1N1); A/California/7/2004(H3N2) and B/Shanghai/361/2002 strains all with 15 mug of haemagglutinin in each 0.5 ml dose. MEASUREMENTS The number of episodes and severity of ARI and AECOPD, classified as outpatient treatment, hospitalisation and requirement of mechanical ventilation, for a period of 1 year before and 1 year after influenza vaccination were recorded. RESULTS The incidence of ARI and AECOPD was 28.6 per 100 person-years prior to vaccination and 9.7 per 100 person-years postvaccination [relative risk (RR) 0.33; p = 0.005). Among the exacerbations because of natural infections prior to vaccination the incidences were 16.12, 42.1 and 33.14 per 100 person-years in the patients with mild, moderate and severe COPD respectively. These were significantly lower following vaccination with the incidences being 6.5, 18.5 and 8.42 per 100 person-years in the same subgroup of patients. Vaccine effectiveness in patients with mild COPD was 60% RR, 0.4 (p = 0.26); in patients with moderate COPD was 60% RR, 0.4 (p = 0.56); and in patients with severe COPD was 75% RR, 0.25 (p = 0.02). The total number of outpatient visits and hospitalisations before vaccination was eight and 14, respectively for a duration of 1 year in the total 87 patients with COPD being studied which decreased significantly to four outpatient visits and four hospitalisations postvaccination (p = 0.02). The overall effectiveness of influenza vaccination was 67%. CONCLUSIONS Influenza vaccination is highly effective in the prevention of ARI. Maximum protection was found to be in patients with severe COPD. Influenza vaccination in patients is associated with fewer outpatient visits and fewer hospitalisations.

Abstract
Interaction between the extracellular matrix and integrin receptors on cell surfaces leads not only to cell adhesion but also to intracellular signaling events that affect cell migration, proliferation, and survival. The vitronectin receptor alpha(v)beta(3) integrin is of key importance in glioma cell biology. The expression of urokinase-type plasminogen activator receptor (uPAR) was recently shown to co-regulate with the expression of alpha(v)beta(3) integrin. Moreover, restoration of the p16 protein in glioma cells inhibits the alpha(v)beta(3) integrin-mediated spreading of those cells on vitronectin. Thus we hypothesized that adenovirus-mediated down-regulation of uPAR and overexpression of p16 might down-regulate the expression of alpha(v)beta(3) integrin and the integrin-mediated signaling in glioma cells, thereby defeating the malignant phenotype. In this study, we used replication-deficient adenovirus vectors that contain either a uPAR antisense expression cassette (Ad-uPAR) or wild-type p16 cDNA (Ad-p16) and a bicistronic adenovirus construct in which both the uPAR antisense and p16 sense expression cassettes (Ad-uPAR/p16) are inserted in the E1-deleted region of the vector. Infecting the malignant glioma cell line SNB19 with Ad-uPAR, Ad-p16, or Ad-uPAR/p16 in the presence of vitronectin resulted in decreased alpha(v)beta(3) integrin expression and integrin-mediated biological effects, including adhesion, migration, proliferation, and survival Our results support the therapeutic potential of simultaneously targeting uPAR and p16 in the treatment of gliomas.

Abstract
PURPOSE The urokinase plasminogen activation system comprises the ligand urokinase plasminogen activator and the receptor urokinase plasminogen activator receptor (uPAR), which play an important role in the activation of matrix-degrading enzymes that enhance the invasion of cancer cells. Earlier studies have indicated that SNB19 glioblastoma cells expressing antisense uPAR constructs lose their invasive properties when injected in vivo. Additional observations indicated that injected antisense uPAR:SNB19 cells were being lost through apoptotic elimination. EXPERIMENTAL DESIGN SNB19, Vector, and SNB19:asuPAR were analyzed to determine cytotoxicity of tumor necrosis factor-alpha-related apoptosis-inducing ligand (TRAIL), receptor expression, and underlying signaling pathways using flow cytometry, immunohistochemistry, RNase protection assay, and c-Jun-NH(2)-terminal kinase activity. RESULTS This study elucidated the susceptibility of antisense uPAR:SNB19 cells to TRAIL under certain experimental conditions in vitro. These uPAR-deficient transfected cells had higher levels of the TRAIL receptors DR4 and DR5 than did the control and vector population as detected by flow cytometry. An RNase protection assay confirmed the elevation of DR4 and DR5 mRNA in the antisense uPAR cells. CONCLUSIONS These findings provide preliminary evidence of a link between TRAIL-induced apoptosis and cell cycle progression in antisense uPAR:SNB 19 cells.

Abstract
Male genital tract infections and non-specific inflammatory conditions may be associated with unexplained infertility. Previous studies have shown the presence of cytokines such as tumour necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) in the semen of infertile men. However, the mechanism of effect of these cytokines on human sperm function is still controversial. The present study was undertaken to investigate the in-vitro effects of TNF-alpha and IFN-gamma on human sperm motion, viability and the hypoosmotic swelling test (HOST). Washed spermatozoa from normal volunteers (n = 9) were incubated in the presence/absence of TNF-alpha (1 microgram/mL) plus IFN-gamma (0.1 microgram/mL). Sperm motility, viability, HOST, and video sequences were recorded at different time intervals (0, 30, 60 and 180 min). Sperm motion parameters were analysed using computer-assisted semen analysis. There was a time-dependent negative effect of TNF-alpha plus IFN-gamma on sperm motility, viability, HOST, and lateral-head displacement (ALH). The maximum decrease was observed between 60 and 180 min for sperm motility (50.8 +/- 5.6%), viability (52.8 +/- 4.0%), HOST (38 +/- 2%) and ALH (4.7 +/- 0.1 microns) compared to control samples (62.2 +/- 2.8, 62.4 +/- 2.9, 58 +/- 4, and 5.3 +/- 0.4, respectively; All p < 0.05). There was no significant effect on sperm straight-line velocity and mean linearity when compared to control. These data suggest that the common inflammatory cytokines TNF-alpha plus IFN-gamma have only partial detrimental effects on sperm motility, viability, membrane integrity and lateral head displacement, which may contribute to the poor fertilizing potential of human spermatozoa during inflammatory conditions.
