Abstract
Intraoperative bleeding poses a substantial challenge, particularly in neuro-spine surgeries leading to complications such as hematomas, infections, and hemodynamic instability. Despite their proven efficacy, use of topical hemostatic agents (THAs) lacks comprehensive published literature and guidelines particularly in the Indian setting. The present study provides the first-ever Indian expert panel recommendations for effective adjunct THA use in different intraoperative bleeding sites and situations in neuro-spine surgeries. A comprehensive approach, encompassing a literature review, followed by experience sharing in a meeting using a survey helped integrate expert opinions in the form of practical algorithms to guide THA selection. Our survey results revealed a strong inclination towards specific THAs, flowable gelatin + thrombin being choice of THA for difficult to access and problematic bleeding situations during tumor removal/resection, transsphenoidal hypophysectomy and skull-based procedures. Both oxidized regenerated cellulose (ORC)/Fibrillar and flowable gelatin + thrombin were recommended for continuous oozing. ORC/Fibrillar was preferred for arteriovenous and cavernous malformations. This expert-panel guidance on THA use aims to optimize hemostat use practices and improve surgical outcomes in neuro-spine surgery.

Abstract
The chemical application is considered one of the most crucial methods for controlling insect pests, especially in intensive farming practices. Owing to the chemical application, insect pests are exposed to toxic chemical insecticides along with other stress factors in the environment. Insects require energy and resources for survival and adaptation to cope with these conditions. Also, insects use behavioral, physiological, and genetic mechanisms to combat stressors, like new environments, which may include chemicals insecticides. Sometimes, the continuous selection pressure of insecticides is metabolically costly, which leads to resistance development through constitutive upregulation of detoxification genes and/or target-site mutations. These actions are costly and can potentially affect the biological traits, including development and reproduction parameters and other key variables that ultimately affect the overall fitness of insects. This review synthesizes published in-depth information on fitness costs induced by insecticide resistance in insect pests in the past decade. It thereby highlights the insecticides resistant to insect populations that might help design integrated pest management (IPM) programs for controlling the spread of resistant populations.

Abstract
Brown planthopper (BPH), Nilaparvata lugens (Stål) and white-backed planthopper (WBPH), Sogatella furcifera (Horváth) are the most destructive sucking insect pests of rice in all rice growing parts of the world. For their accurate identification at early stages, we have developed two species-specific markers (SNL4F and SNL4R for BPH; SNF2F and SNF2R for WBPH) based on mitochondrial cytochrome oxidase I (COI) for their easy detection using Polymerase Chain Reaction (PCR). The markers were developed based on nucleotide differences in COI gene and were subjected to various tests based on PCR-based gel images. The designed primers were cross-checked with five other species, which confirmed their specificity. The primers were also found to be efficient in identification of their respective species (BPH and WBPH) in all the individuals sampled from different regions of India. The lowest detection sensitivity of both the primers was up to 1 ng/µl DNA after testing them through a series of varied DNA concentrations. The species-specific primers developed in this study will help in easy and rapid identification of BPH and WBPH in all the stages of their development and in turn facilitate their timely management.

Abstract
BACKGROUND The bacterial contaminants in the semen are a major concern for most of the semen production laboratories because they adversely affect the semen quality. During sperm cryopreservation, the inclusion of antimicrobials in extenders may help to minimize bacterial growth. However, due to bacterial resistance to commonly used antimicrobials, they cannot fully assure microbiological safety to the frozen semen. OBJECTIVE To estimate the microbial load and antibiogram of microorganisms isolated from the fresh and frozen bull semen. MATERIALS AND METHODS The bacterial load was estimated in fresh and frozen semen samples of crossbred Frieswal bulls by the pour plate method. Microorganisms were identified as Gram positive and Gram negative by Gram staining. The representative bacterial colonies were streaked onto different specific media which were further confirmed by biochemical tests. Bacterial isolates were subjected to in vitro antibiotic sensitivity test. RESULTS The average microbial load of fresh and frozen semen samples was found to be 8397.4 ± 524.3 cfu per mL and 680.9 ± 105.4 cfuper mL, respectively. Microorganisms belonging to Staphylococcus aureus, Staphylococcus epidermidis, Proteus, Klebsiella, Bacillus cereus, Bacillus subtilis, Actinomyces, E. coli, Rhodococcus, Neisseria and Micrococcus were identified in the semen samples. The antibiotic sensitivity testing of the bacterial isolates revealed that benzyl penicillin was found to be the least effective against the isolated organisms while gentamicin and spectinomycin were found to be most effective among the antibiotics used. Lincomycin, tylosin and streptomycin showed moderate efficacy against the bacterial isolates. CONCLUSION Gentamicin, tylosin, lincomycin, and spectinomycin (GTLS) antibiotic combination is more effective against bacterial isolates and may be added to semen extender to better control bacterial load and semen quality. doi.org/10.54680/fr22610110512.

Abstract
The brown planthopper, Nilaparvata lugens (Stål) is a major sucking insect pest of rice. This insect has long been considered as migratory; however, its route in India is still unknown. Hence, to find out its migration route genetic diversity, genetic structure and gene flow of 16 N. lugens populations from major rice growing regions of India was studied based on mitochondrial cytochrome oxidase I (COI). The results revealed a high genetic homogeneity among the populations on the basis of genetic diversity statistics and neutrality tests. There was a prevalence of a single major haplotype across the country. No spatial relevance was found with the genetic structure of the populations indicating presence of excessive gene flow among them. Extensive gene flow among populations was also confirmed with the presence of higher number of immigrants in North, Central, and East India. To further clarify the migration sources, 48 h air-mass reverse trajectory was performed for Varanasi just aftermath of cyclones Amphan and Yaas, which disclosed Eastern/Northeastern states along with Bangladesh and Myanmar as the possible source areas. Overall, the results revealed a single panmictic homogeneous population of N. lugens in India with extensive gene flow as a consequence of their migration. These findings will help in better forecasting enabling efficient regional management of this important rice pest.

Abstract
BACKGROUND Cryopreservation process negatively affects spermatozoa functions. Humanin, a small polypeptide encoded in the mitochondrial genome, is well known for its role in cell survival. OBJECTIVE To quantify the endogenous levels of humanin in seminal plasma of crossbred Frieswal bulls and to study its role in cryoprotection. The presence of humanin in bull spermatozoa was also investigated. MATERIALS AND METHODS A total of 40 semen samples were separated into two groups based on the initial progressive motility (IPM): Good (IPM >70%) and Poor (IPM <50%) groups; and/or based on the post-thaw motility (PTM): Freezable (PTM>50%) and Non-freezable (PTM < 50%) groups. Humanin concentration in seminal plasma (SP-HN) was quantified using ELISA. RESULTS SP-HN concentration ranged from undetectable to 67.6 pg/mL with a median level of 35.2 pg/mL. SP-HN level was significantly higher in the good quality semen group than in the poor quality semen group (p<0.001), and also significantly higher in the freezable group than in the non-freezable group (p<0.001). SP-HN level was positively correlated with initial progressive motility, post-thaw semen motility, viability, acrosome intactness and plasma membrane integrity, but negatively correlated the level of reactive oxygen species and malondialdehyde content. Immunochemical localization showed the presence of humanin in the proximal region of the middle piece of spermatozoa. CONCLUSION Endogenous humanin level had significant correlation with semen quality and might protect sperm cells against freeze-induced oxidative stress. doi.org/10.54680/fr22510110712.

Abstract
BACKGROUND The increasing use of nanoparticles (NP) for gender-selected spermatozoa, sperm-enriched semen and novel extenders raises the concern of undesirable effects on fertility and sperm function. OBJECTIVE To investigate the effects of gold (Au-), silver (Ag-), and titanium dioxide (TiO2-) NPs on the motility and sperm functions in bovine spermatozoa at various stages of cryopreservation. MATERIALS AND METHODS Frieswal (Sahiwal × Holstein Friesian) bull semen ejaculates (N = 24) were challenged with unconjugated and ligand-free Au-, Ag-, and TiO2-NPs. RESULTS At post-dilution (fresh) stage, there was no significant difference observed in progressive motility and viability amongst the control and any nanoparticle-treated groups, though plasma membrane integrity was significantly reduced in nanoparticle-treated groups (p < 0.05). The acrosome intactness was also significantly reduced in the groups of Ag-NP and TiO2 -NP (p < 0.05), while there was no effect observed in the Au-NP group. At post-equilibration stage, a significant reduction in motility, viability, and plasma membrane integrity was observed in all three nanoparticle-treated groups (p < 0.05). There was no difference in intact acrosome between the control and Au-NPs groups; which was significantly higher than the Ag-NP and TiO2 -NP groups (p < 0.05). At post-thaw stage, all NP groups resulted in a significant reduction of motility, viability, acrosome intactness and plasma membrane integrity (p < 0.05). Besides, TiO2-NPs appear to be significant more toxic (p < 0.05) among three NP groups, and Au-NPs appear to be lesser toxic. CONCLUSION Bovine spermatozoa are adversely affected by Au-, Ag- and TiO2 -NPs that may impair sperm motility and other functions. doi.org/10.54680/fr22310110512.

Abstract
Funding Acknowledgements Type of funding sources: None. Introduction Myocardial injury during acute COVID-19 infection is well characterised however, its persistence during recovery is unclear. Purpose We assessed left ventricle (LV) global longitudinal strain (GLS) and right ventricular (RV) free wall longitudinal strain and RV global longitudinal strain (RV-GLS) using speckle tracking echocardiography (STE) in COVID-19 recovered patients (30-45 days post recovery) and studied its correlation with various parameters. Methods Of the 245 subjects screened, a total of 53 subjects recovered from COVID-19 infection and normal LV ejection fraction were enrolled. Routine blood investigations, inflammatory markers (on admission) and comprehensive echocardiography including STE were done for all. Results All the 53 subjects were symptomatic during COVID-19 illness and were categorized as mild: 27 (50.9%), moderate: 20 (37.7%) and severe: 6 (11.4%) COVID-19 illness. Reduced LV GLS was reported in 22 (41.5%), reduced RV-GLS in 23 (43.4%) and reduced RVFWS in 22 (41.5%) patients respectively. LVGLS was significantly lower in patients recovered from severe illness (mild: -20.3 ± 1.7%; moderate: -15.3 ± 3.4%; severe: -10.7 ± 5.1%; P < 0.0001). Similarly, RVGLS (mild: -21.8 ± 2.8%; moderate: -16.8 ± 4.8%; severe: -9.7 ± 4.6%; P < 0.0001) and RVFWS (mild: -23.0 ± 4.1%; moderate: -18.1 ± 5.5%; severe: -9.3 ± 4.4%; P < 0.0001) were significantly lower in subjects with severe COVID-19. Subjects with reduced LVGLS as well as RVGLS and RVFWS had significantly higher interleukin-6, C-reactive protein, lactate dehydrogenase and serum ferritin levels during index admission. Conclusions Subclinical LV and RV dysfunction was seen in majority of COVID-19 recovered patients. Patients with severe disease during index admission had far lower LV and RVGLS as compared to mild and moderate cases. Our study highlights the need for close follow-up of COVID-19 recovered subjects in order to determine the long-term cardiovascular outcomes.

Using an in vitro whole blood culture model, cells were continuously exposed to heat stress (at 42 °C) for 6 h. Methylation levels of five genes, viz., GPX1, HSP70, HSP90, c-FOS, and JUN were estimated by SyberGreen-based quantitative methylation-specific PCR (qMSP) assay. CpG methylation kinetics at different time points of heat stress (0.5, 1, 2, 4, 6 h) were analyzed using mixed ANOVA. The initial methylation level, estimated at 37 °C, of HSP70 was significantly high in the Sahiwal breed. A significant (p<0.001) time-dependent hypomethylation of an antioxidant gene (GPX1) CpG islands was detected at the acute phase of the stress. Heat shock protein gene (HSP70) showed a similar CpG methylation kinetics where the hypomethylation was prominent from 1 h and persisted up to 4 h. The heat stress responses of both Sahiwal and Frieswal cattle were identical as there was no distinctiveness in the methylation kinetics of CpG islands of studied genes. The acclimatization of Frieswal cattle-a breed developed in India over the years to the tropical climatic conditions, maybe one of the reasons for this similarity. Thus, the present study results could pave a path to understand the molecular mechanism of heat stress and adaptation of indigenous and crossbred cattle populations to the changing scenario in tropical climate conditions.

Abstract
Urinary stones are a common health problem, necessitating frequent outpatient visits and hospital admissions. Ureteric stones demand special attention, given their propensity for upstream hydroureteronephrosis and loss of renal function. They are usually predisposed by diverse anatomical, functional or metabolic abnormalities of the urinary tract and have an early symptomatic presentation. We report an exceptional clinical presentation of a huge ureteric stone yet functional renal moiety with no obvious anatomical or metabolic predilection for urolithiasis, and its minimally invasive management in a young woman. We emphasise that swift salvaging of the renal function is of utmost importance in these cases. Open exploration can be avoided in favour of laparoscopic ureterolithotomy with better cosmesis and early recovery.

Abstract
Despite many cryopreservation techniques in bovine semen, various stressors' detrimental effects remain a significant issue. The present study targeted to assess the role of semen quality parameters, sperm function tests, lipid peroxidation, reactive oxygen species (ROS), and different antioxidants in the cryopreservation of bovine semen. Further, the kinetics of lipid peroxidation, ROS, and antioxidants on repeated semen collection under short ejaculatory abstinence were studied. We designed a comparative study where bulls were grouped into good and low freezable semen groups (Freeze-groups) based on their post-thaw motility. All the bulls included had similar initial motility and qualified minimum standards for initial semen parameters viz. semen volume and sperm concentration. The present study detected a higher lipid peroxidation and ROS viz. superoxide anions (•O2-) and a lower total antioxidant capacity (TAC) in the low freeze-group compared to the good freeze-group. The ROS and antioxidants showed unique kinetics on repeated semen collection at short intervals, and no significant change was detected in semen volume, sperm motility, and sperm concentration. This study detected higher head abnormalities and poor acrosome integrity in the low freeze-groups. The present study results indicated that the sperm head might be the most vulnerable part of the sperm to cryopreservation stress. The present study finds significantly higher lipid peroxidation and ROS levels and reduced antioxidant capacity as the primary reasons for low cryopreservability. Further, repeated semen collection with a shorter or lack of abstinence does not impose any significant change in the semen volume and sperm concentration; moreover, it could be beneficial for higher antioxidant levels and lower lipid peroxidation levels. As seminal plasma has both inhibitory and stimulatory roles in sperm function and cryopreservation, identifying the critical role players of seminal plasma and identifying sperm related changes in cryopreservation could predict the cryopreservability potential of semen.

Abstract
Amine group-containing isoreticular metal-organic framework (IRMOF-3) particles are utilized for the first time as a trinitrotoluene (TNT) sensing material. IRMOF-3 particles are synthesized using zinc nitrate as a metal precursor and 2-amino-1,4-benzenedicarboxylic acid as a linker. The nitrogen-doped carbon quantum dots (NCQDs) are synthesized from citric acid and ethylenediamine as carbon and nitrogen precursor, respectively. The NCQDs are conjugated with IRMOF-3 particles as IRMOF-3/NCQDs. The TEM micrograph revealed the average size of IRMOF-3 particles to be 363.66 nm. The photoluminescence emission intensity of IRMOF-3 particles at λem 430 nm is highly increased in the presence of NCQDs (λex 330 nm). Both the as-synthesized IRMOF-3 and IRMOF-3/NCQD particles are explored for TNT detection to compare the effect of NCQDs on the IRMOF-3 particle surface. Lower limit of detection (7.5 × 10-8 M) and higher Stern-Volmer constant (4.46 × 106 M-1) are achieved by IRMOF-3/NCQD particles. The association constant also increased from 5.3 × 104 to 2.78 × 106 M-1 after the conjugation of IRMOF-3 particles with NCQDs. Moreover, enhanced selectivity for TNT over trinitrophenol is achieved using the IRMOF-3/NCQD particles. Graphical Abstract.

Abstract
Impact of global warming on the dairy industry has gained attention due to huge economic losses through low production and fertility caused by heat stress. Exposure to hyperthermia provokes a series of complex responses in mammals which are been related to morphological and physiological alterations including the production of reactive oxygen species (ROS). A quantitative spectrophotometric based nitroblue tetrazolium (NBT) reduction assay was used to estimate the superoxide anion (•O2-) level in heat stressed (at 42 °C) whole blood cultures of native and crossbred bulls (Sahiwal and Frieswal), in vitro. The breed effect in the kinetics of •O2- production at different time periods of continual heat stress was analyzed by repeated measures ANOVA. Comparison between different time periods in reference to 37 °C was analyzed by paired t-test. The •O2- level was significantly different (p < 0.05) between cells at 37 °C and 42 °C at different periods of incubation. Kinetics study showed increment of •O2- production on the acute phase of stress followed by a reduction in both Sahiwal and Frieswal breeds. In Sahiwal breed, the inflated superoxide level continued abated till 4 h and raised again at 6 h, while in Frieswal •O2- level reverted to raise sooner with in 2 h of incubation itself. Contrarily, kinetic of •O2- level in plasma showed a significant reduction (p < 0.001) at 30 min of 42 °C incubation followed by increment of •O2- level. Further, the breed variation was significant (p < 0.05) and a significant high reduction of •O2- level was observed in Sahiwal breed. Our finding indicates that, a better and longer •O2- production homeostasis and higher plasma scavenging ability of native breed may be one of the reasons for the higher thermal tolerance of these breeds in tropical climate.

Abstract
INTRODUCTION Hemostatic disorders are often missed in women with bleeding particularly menorrhagia. Preexisting hemostatic disorders are now known as common risk factor for postpartum hemorrhage and prolonged bleeding in puerperium. Females with bleeding complaints constitute an important population referred to hematology clinic. Hence, we aim to evaluate the type and frequency of hemostatic disorders among females presenting with bleeding in a tertiary care hospital and a basic hemostatic laboratory. METHODS Three-year data were retrospectively analyzed for 200 females with various bleeding complaints. Due to resource constraints, a hemostatic workup was done with prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen assay, clot solubility test, mixing studies, specific factor assays, platelet function test, and von Willebrand factor antigen level. RESULTS A total of 200 females were investigated to identify the cause of their bleeding. Thirty-five of 200 (17.5%) females were found with an underlying bleeding disorder. Of these 35 females, 65.7% presented with bleeding from more than 1 site. Most common bleeding manifestation was spontaneous bruising in 18 of 35 (51.4%) patients followed by petechiae (48.6%). Inherited bleeding disorders were noted in majority. The most common inherited bleeding disorder identified was von Willebrand disease (VWD) in 34.3% females. Second most common disorder was Glanzmann's thrombasthenia accounting for 22.8%. Rare coagulation factor deficiency, such as factors VII, X, and XIII deficiencies, was noted. Three cases revealed acquired causes of coagulation defects. CONCLUSION Underlying hemostatic defects should be searched for in women with unexplained bleeding complaints. This will not only help in diagnosis but also in proper management for future hemostatic challenges.

Abstract
Vehicle-generated toxic pollutants are composed of gaseous smoke and particulate byproducts accumulated as a black substance at its exhaust. This particulate matter (soot) is utilized for the green synthesis of highly stable, non-toxic, environment friendly, carbon quantum dots (CQD). The CQDs are synthesized via the simple hydrothermal route in the absence (C1) and presence (C2) of oxidants. The as-synthesized CQDs are amine functionalized using ethylenediamine. The amine functionalized CQDs (C1N and C2N) are explored for trinitrotoluene detection. From transmission electron microscopy, the average size of C1 and C2 was found to be about 4.2 nm and 5.6 nm respectively. The incorporation of amine groups lead to an increase in quantum yields from 5.63% to 12.7% for C1 and from 3.25% to 8.48% for C2 QDs. A limit of detection (LOD) of 13 ppb was displayed by C1N while the LODs of 11 ppb and 4.97 ppb were delivered by C2N at λex 370 nm and λex 420 nm respectively. The Stern–Volmer constant for C1N is 2.02 × 106 M−1 while for C2N at λex 370 nm and λex 420 nm is 0.38 × 106 M−1 and 0.48 × 106 M−1 respectively. Furthermore, C1N presents high selectivity for TNT compared to C2N. Owing to their higher luminescence, C1N particles are successfully demonstrated for their applicability in intracellular TNT detection. Vehicle-generated toxic pollutants are composed of gaseous smoke and particulate byproducts accumulated as a black substance at its exhaust.![]()

Abstract
INTRODUCTION Central nervous system (CNS) involvement in acute lymphoblastic leukemia (ALL) is diagnosed traditionally by cytopathology (CP) of the cerebrospinal fluid (CSF). Role of flow cytometry (FC) to diagnose CNS involvement has not been extensively investigated. METHODS We aimed to detect CNS involvement in 42 ALL patients (33 B-ALL, nine T-ALL) at diagnosis by FC and comparing it with CP and to correlate it with known risk factors for CNS disease like Lactate dehydrogenase (LDH). A receiver operating characteristic curve was used to determine the cutoff of LDH to predict CSF involvement. For the analysis of categorical/quantitative variables, Fisher's exact test was used. For the analysis of continuous variables, Mann-Whitney test was used. A P value of <.05 was taken as significant. RESULTS CP and FC were positive in five (11.9%) and 11 patients (26.14%) respectively with FC detecting a significantly higher level of involvement (P=.001). All CP-positive cases were FC positive. A LDH value of >472 U/L had a sensitivity of 61% and specificity of 62.5% for diagnosis of CSF involvement by FC. CONCLUSIONS CSF FC detects CNS disease in ALL patients at diagnosis at a rate double than CP alone and is statistically associated with an elevated LDH level. It should be incorporated in the evaluation of CSF to detect CNS involvement.

Abstract
INTRODUCTION Coronary artery disease (CAD) is emerging as the biggest killer of the 21st century. A number of theories have been postulated to explain the aetiology of atherosclerosis. The present study attempts to elucidate the interaction, if any, between inflammation, oxidative stress and dyslipidaemia in CAD. METHODS A total of 753 patients undergoing angiography were evaluated and 476 were included in the study. The parameters studied included complete lipid profile, and apolipoprotein B, ferritin and nitric oxide (NO) levels. Statistical analysis was carried out to determine the interrelationship between these parameters and the best predictor of CAD risk. Cut-off points were determined from the receiver operating characteristics curves, and the specificity, sensitivity, positive predictive value, negative predictive value, odds ratio and confidence intervals were calculated. RESULTS The levels of the parameters studied increased with the stenotic state and a positive correlation was observed between ferritin, NO and apolipoprotein B. NO emerged as the most reliable predictor of CAD, with an area under the curve of 0.992 and sensitivity and specificity of 97 and 98%, respectively. CONCLUSION Environmental and genetic risk factors for CAD interact in a highly complex manner to initiate the atherosclerotic process. These risk factors should be considered mutually inclusive, not exclusive when devising pharmacological interventions, as multi-factorial risk management is the cornerstone of CAD management.

Abstract
Mammalian circadian locomotor output cycles kaput (CLOCK) gene encodes a transcription factor that affects both the persistence and the period of circadian rhythms. Earlier reports suggested that CLOCK gene might be associated with male infertility in human. Present investigation, for the first time, reports that CLOCK gene expresses differentially between good and poor quality crossbred bull semen. The relative expression of CLOCK was significantly (p < 0.05) higher among good quality bull semen than motility-impaired ones. Clusterins (CLU) are series of genes associated with a variety of physiological activities including spermatogenesis, apoptosis and degenerative disease conditions. In the present context, we also investigated that the expression of CLU gene was significantly (p < 0.05) higher among motility-impaired crossbred bull semen compared to the good quality one.

Abstract
BACKGROUND The incidence of aplastic anaemia (AA) is higher in Asia than in the West. The precise incidence of AA in India is not known due to lack of epidemiological study. 20-40% of pancytopenic patients in referral centres are of aplastic anaemia. PATIENTS AND METHODS This was an analysis of 1501 patients diagnosed with aplastic anaemia over a period of seven and half years (January 2007- June 2014) attending the Aplastic clinic of department of haematology of All India Institute of Medical Sciences, New Delhi. The details regarding medical history, physical examination, complete blood count, bone marrow aspirate and biopsy, treatment received, were retrieved. Inherited bone marrow failure was screened in patients below 35 years. Treatment response was analysed for various treatment modalities. RESULTS 1501 patients of AA from 20 different states of India were analysed. The bulk of patients were from Uttar Pradesh (28.7%), Bihar (23.6%), Delhi/NCR (20%) and Haryana (7%).The average number of new aplastic anaemia patients enrolled per year 214 (range: 101 -263). The median age at presentation was 25 years (range 2-83),with M;F - 2.3:1. Severity of AA revealed: severe (SAA): 75%, very severe (VSAA): 15%, non-severe (NSAA): 10%. Inherited bone marrow failure syndromes constituted 5% (75 patients) of all aplastic anaemia patients. The most common clinical presentations were pallor (97%), bleeding manifestations (69.6%) and fever (54%). The haematological parameters showed: median level of haemoglobin level: 5.9 gm/dL, WBC: 2700/mm3, ANC: 380/mm3, platelet: 1 0000/mm3. PNH clone was present in 13.5% of patients. 107 patients (7%) were lost to follow up or expired before any treatment was initiated. Only 69 patients (4.5%) received treatment with HLA-matched sibling stem cell transplantation and another 232 (15.5%) patients received ATG plus cyclosporine as immunosuppressive therapy. Seven hundred thirteenpatients (47.5%) received cyclosporine. The overall response to various treatment modalities was: HLA matched sibling haematopoietic stem cell transplant: 75.3%, Anti-thymocyte globulin plus cyclosporine: 58.7%, cyclosporine plus androgen: 45.6%, cyclosporine alone: 32.2%. CONCLUSION Management of AA is a real challenge in developing countries.This is one of the largest case series from a single centre from India. It is our endeavour to reduce the detrimental outcome by increasing awareness among patients and referring physicians to reduce the delay between diagnosis and treatment.

Abstract
The aim of this study was to evaluate scar thickness in cases of pregnancy with previous caesarean section, by trans-vaginal sonography (TVS) and magnetic resonance imaging (MRI), and to correlate precision of radiologically-measured scar thickness with actual measurement of scar thickness. A total of 35 pregnant patients with previous caesarean section planned for elective caesarean section, were evaluated prospectively. Their scar thickness was measured by TVS and MRI on the day of elective repeat caesarean section. These measurements were correlated with each other and with scar thickness measured during elective repeat caesarean section by using a caliper. The correlation coefficients between scar thickness measured by TVS and MRI with peroperative evaluation with a caliper, were +0.72 and +0.59, respectively. The study concluded that as MRI is a costlier modality and TVS has better correlation coefficient with actual scar thickness, TVS can be considered to be the better modality for antenatal scar thickness measurement.

Abstract
Uterine arteriovenous malformations are rare lesions which have a varied presentation that may range from the patient being asymptomatic to varying degrees of menorrhagia. It can be diagnosed by Doppler sonography but a strong index of suspicion is necessary. Management of this condition depends on presentation and available resources. In asymptomatic patients, we can leave the patients on regular follow-up as many lesions regress spontaneously. In patients with excessive haemorrhage not responding to embolisation or when facilities of embolisation are not available, hysterectomy needs to be done. Uterine artery embolisation should be considered the optimum treatment, as it has a high success rate coupled with few complications and also has fertility-preserving potential. Clinical follow-up usually suffices but sonography may occasionally be required.

Abstract
We describe the clinical, hematological and histomorphological features in children of primary myelodysplastic syndrome (MDS) seen at the All India Institute of Medical Sciences over three years (Jan 2001-Jan 2004). Twenty-one patients of primary MDS aged 17 year or less were classified using the latest proposed WHO classification for Pediatric MDS. The median age was 9 years with male predominance (80%). Pallor was present in all the cases while fever and bleeding diathesis was present in more than 50% of the cases. Morphological assessment of the peripheral blood showed macrocytosis in 50%, pancytopenia in 15% and blast cells in 45% of cases. A complete analysis of clinical features in conjunction with the bone marrow profile revealed 8 cases of refractory cytopenia (RC), 3 cases of refractory anemia with excess blasts (RAEB), 5 cases of refractory anemia with excess blasts in transformation (RAEB-T), 4 cases of Juvenile myelomonocytic leukemia (JMML) and a solitary cases of acute myeloid leukemia (AML) in Downs syndrome. These children were followed up from 1-36 months (mean 15 months). Three patients of RAEB-T progressed to AML within 3-4 months. RC had the best prognosis and all are alive and under regular follow up. The solitary case of AML of Downs syndrome died 1.5 months after initial diagnosis. All 3 cases of RAEB are under regular follow-up and doing well. Three cases of RAEB-T died (all had progressed to AML); the remaining 2 cases were lost to follow up. Of the 4 cases of JMML 1 died within 6 months of diagnosis; the other 3 cases are under regular follow up of whom 1 has a progressively increasing blast count. We conclude that the latest proposed WHO classification for Pediatric MDS can be successfully applied to all cases of primary MDS.

Abstract
Haemoglobin E beta thalassemia (HbE beta thalassemia) has a remarkable variability in clinical expression ranging from a mild form of thalassemia intermedia to a transfusion dependent condition. An overlap between the mild variety of HbE beta thalassemia and homozygous HbE disease is common, however, differentiation is required for early institution of therapy and for predicting the later clinical course. Fifty cases of Hb E syndrome comprising of 43 cases of Hb E beta thalassemia and 7 cases of homozygous HbE disease were studied. Their clinico- haematological features and results of high performance liquid chromatography (HPLC) were analysed.

Abstract
Cytochemical staining for leukemia typing is declining in hematology laboratories, but the use of flow cytometry may not be possible in some settings. Aberrant cytochemical nonspecific esterase/α-naphthyl acetate esterase (NSE/αNAE) positive B-lymphoblasts can cause confusion with monoblasts, a potentially dangerous pitfall. This unusual cytochemical NSE/αNAE positivity had been associated with relatively poorer outcome of acute lymphoblastic leukemia (ALL) in the era prior to the advent of routine multicolor flow cytometric immunophenotyping. We reviewed morphological, cytochemical and flow-cytometric data from five cases of B-lineage ALL that showed NSE/αNAE positivity and were diagnosed definitively using multi-parametric flow cytometric immunophenotypic analysis. Diffuse or dot-like (localized) strong cytochemical NSE/αNAE activity was detected in all cases and all showed one or more features of high risk disease. The number of NSE/αNAE positive blasts in the marrow varied from 10 to 75%. The morphological differential diagnoses included T-lymphoid lineage ALL and acute monoblastic leukemia (AML-M5). Flow cytometric data revealed B-lineage antigens and the absence of monocytic or other myeloid markers resolved the diagnosis. These cases underscore the importance of immunophenotyping in all cases of suspected ALL regardless of the cytochemical findings. Although the numbers are small, the association with high risk disease observed in all five of our cases may corroborate the previously reported poor prognostic value of such aberrant cytochemical staining.

Abstract
PREAMBLE: The potential risk of contrast-induced acute kidney injury (CI-AKI) has made utilization of coronary angiography in the work-up for the diagnosis of coronary artery disease in CKD quite low.(1) This is in contrast to increasing prevalence and severity of CAD as the serum creatinine rises.(2) In fact most CKD patients will succumb to CAD and not to ESRD.(3) Thus the judicious use of CAG/PCI in this setting is of prime importance but underused. The CSI began to develop guidelines for Indian context as most guidelines are those developed by ACC/AHA or ESC. The aim was to assist the physicians in selecting the best management strategy for an individual patient under his care based on an expert committee who would review the current data and write the guidelines with relevance to the Indian context. The guidelines were developed initially in June 2010 as an initiative of Delhi CSI. Three interventional cardiologist (SB, AS, KKS), one nephrologist (SCT) and two clinical cardiologists (ST, RG) along with Dr. Roxana Mehran (New York) and Dr. Peter McCullough (Missouri), U.S.A.; were involved in a three-way teleconference to discuss/debate the data. This was presented by SB, and over the next two hours each data subset was debated/agreed/deleted and this resulted in the "Guidelines for CAG in Renal Dysfunction Patients". These were then written and re- circulated to all for final comments. Further, these guidelines were updated and additional Task Force Members nominated by Central CSI were involved in the formation of the final CSI Guidelines. Both (Roxana Mehran and Peter McCullough) reviewed these updated Guidelines in October 2012 and after incorporating the views of all the Task Force members-the final format is as it is presented in this final document.

Abstract
OBJECTIVE. To study the prevalence and type of functional somatic complaints in patients with first-episode depression. METHODS. A total of 164 patients attending the outpatient department of a general hospital psychiatric unit were evaluated using the Patient Health Questionnaire-15 (PHQ-15) and Hamilton Depression Rating Scale (HDRS). RESULTS. More than half of the sample were male (n = 85; 52%) and most of the subjects were married (n = 128; 78%). The mean (standard deviation) HDRS score was 19.9 (5.4). All patients had at least 1 functional somatic complaint, and that the mean (range) number of functional somatic complaints per patient on the PHQ-15 was 8 (1-15). The most common functional somatic complaints included feeling tired or having little energy (93%); trouble sleeping (80%); nausea, gas and indigestion (68%); headache (68%); pain in arms, legs, or joints (66%); and feeling the heart racing (65%). Total PHQ-15 scores indicated the presence of moderate-to-severe severity of functional somatic complaints. Back pain, as well as pain in arms, legs, or joints, were found to be more common in females. The number and severity of functional somatic complaints did not differ significantly in relation to other socio-demographics (locality, marital status, age, education, income) and clinical variables (duration, physical co-morbidity, and atypical features). CONCLUSIONS. Functional somatic complaints are quite prevalent in subjects with first-episode depression. Hence, clinicians should routinely evaluate patients with depression for these symptoms.
