Abstract
To translate, validate and test the reliability of Kannada version of "EORTC QLQ-H&N43" and "NCCN Distress Thermometer and Problem list" version 2.2022. The English version of "EORTC QLQ H&N43" and "NCCN Distress thermometer and Problem List" version 2.2022 tools were translated into Kannada language according to standard guideline. The translated version was validated by EORTC and by using content validity index (CVI). Further, the reliability of validated tools was established via test-retest and internal consistency method whereas construct was determined via spearman rank correlation. The Cronbach alpha value > 0.7 and correlation coefficients (ρ) < 0.05 was considered as significant. The Kannada version of "EORTC QLQ-H&N43" was validated by EORTC as well as by experts whereas NCCN distress tool was validated only by experts with average CVI score of 1 and 0.97 respectively. Out of total 80 patients, 50% were head and neck cancer (HNC) patients and 50% belonged to other cancer types. Kannada version of EORTC QLQ-H&N43 and NCCN distress tool was found to be reliable among HNC and general cancer patients respectively with the Cronbach alpha value between 0.819-1 and 0.71-1 for all the domains. Further, only 7.72% of EORTC QLQ-H&N43 and 13.33% of NCCN distress tool construct were significantly correlated with construct of EORTC QLQ-C30 (p < 0.05). The Kannada version of QoL and distress instrument was found to be valid and reliable to use among HNC and/ general cancer patients respectively. Thus, this method of translation, validation and reliability testing can be used as a novel practice in healthcare.

Abstract
Melanoma,also known as a 'black tumor', begins in the melanocytes when cells (that produce pigment) grows out of control. Immunological dysregulation, which raises the risk for multiple illnesses, including melanoma, may be influenced by stress tiggered through viral infection, long term effects of ultraviolet radiation, environmental pollutants etc. Borapetoside C is one of the phytoconstituents from Tinospora crispa, and its biological source has been reported for its antistress property. Network pharmacology and KEGG pathway analysis of borapetoside C-regulated proteins were conducted to identify the hub genes involved in melanoma development. Further, a molecular docking was performed between borapetoside C and targets involved in melanoma. Further, the top 3 complexes were selected based on the binding energy to conduct molecular dynamics simulations to evaluate the stability of ligand-protein complex followed by principal component analysis and dynamic cross-correlation matrix. In addition, borapetoside C was also screened for its pharmacokinetics and toxicity profile. Network Pharmacology studies and KEGG pathway analysis revealed 8 targets involved in melanoma. Molecular docking between borapetoside C and targets involved in melanoma identified 3 complexes with minimum binding i.e. borapetoside C- MAP2K1, MMP9, and EGFR. Further, molecular dynamics simulations showed a stable complex of borapetoside C with MMP9 and EGFR. The present study suggested that borapetoside C may target MMP9 and EGFR to possess an anti-melanoma property. This finding can be useful in developing a novel therapeutic agent against melanoma from a natural source.Communicated by Ramaswamy H. Sarma.

Abstract
INTRODUCTION Chemotherapy is an integral part of cancer management which is associated with phlebitis in around 70% of patients receiving intravenous chemotherapy infusion. Thus, we aimed to estimate the incidence, severity, and management of phlebitis associated with chemotherapy infusion among cancer patients. METHODS A prospective study was conducted among 145 patients receiving intravenous chemotherapy for the duration of six months in the oncology department. The relevant data for phlebitis was obtained and assessed using Phlebitis Grading Scale and Visual Analogue Scale for the assessment of severity and pain due to phlebitis, respectively. RESULTS Out of 145 patients, female (56.6%) patients predominated over male patients (43.5%) with a mean age of 53.5 ± 11.82 years. Phlebitis was encountered in 30.34% of patients among whom 22.8% (33) were females followed by 7.6% were males and the majority of patients (13.1%) were from the 46 to 60 years age group. Phlebitis was observed frequently among stage 2 (11%) and satge 4 (11%) patients. The highest incidence of phlebitis was seen among hypertensive (34.09%) and diabetic patients (27.27%) followed by those receiving chemotherapy through the 20-gauge intravenous cannula (22.8%) and 22-gauge (6.9%). Platinum compounds (56.8%) were commonly associated with phlebitis, followed by cyclophosphamide (20.5%). Heparin and benzyl nicotinate topical gel were used to treat phlebitis. CONCLUSION Platinum and cyclophosphamide are commonly associated with phlebitis which can be managed by topical heparin plus benzyl nicotinate. Phlebitis shouldn't be ignored as it has a high incidence, affects the quality of life, and increases the treatment burden.

Abstract
OBJECTIVE To provide an integrated approach for deprescribing practice in oncology setting. DATA SOURCES The data on deprescribing in oncology settings has been retrieved from the PubMed, Scopus and Google Scholar. We used "deprescribing," "potentially inappropriate medication" and "cancer" as a keyword for the conducting general search. The articles relevant to guidelines or tools used to deprescribe in cancer care were included. DATA SUMMARY The nature of cancer, its treatment strategies, adverse effects of therapy and multimorbidity impact negatively on quality of life (QoL). Further, they invite polypharmacy which puts the patient at higher risk of drug-related problems like drug interactions, adverse drug reactions and addition of potentially improper medications, etc. In older adults with cancer, the incidence of potentially inappropriate medications (PIMs) was between 41% and 52%. Over the decades, multiple strategies have been developed to assess the appropriateness of therapy. One such approach is deprescribing. OncPal and oncoSTRIP (Systematic Tool to Reduce Inappropriate Prescribing) are the cancer specific guidelines whereas BEERs criteria, Screening Tool to Alert to Right Treatment/Screening Tool of Older Person's Prescriptions criteria (START/STOPP criteria), medication appropriateness index (MAI) are the cancer nonspecific tools to identify PIM among cancer patients. Here, we provided an integrative approach and algorithm for deprescribing in oncology setting which includes patient and caregiver goals, life expectancy (LE), review of medications, determining medication appropriateness, assessment of time to benefit (TTB), symptomatic and asymptomatic care, identifying medications to cease, implementation of the plan, monitoring and reviewing. CONCLUSION Deprescribing in oncology setting is a novel and effective patient-centric approach to counteract the use of PIM, which helps to mitigate polypharmacy, drug-drug interactions, and adverse effects.

Abstract
Only 13% of head and neck cancer (HNC) patients respond to cetuximab therapy despite its target (EGFR) is expressed in about 80-90% of HNC patients. However, this problem remained unresolved till date despite of numerous efforts. Thus, the current study aimed to establish hub genes involved in cetuximab resistance via series of bioinformatics approach. The GSE21483 dataset was analysed for differentially expressed genes (DEGs) using GEO2R and enrichment analysis was carried out using DAVID. STRING 11.5 and Cytoscape 3.7.2 were used for protein-protein interactions and hub genes respectively. The significant hub genes (p < 0.05) were validated using ULCAN and Human protein atlas. Validated genes were further queried for tumor infiltration using TIMER2.0. Out of total 307 DEGs, 38 hub genes were identified of which IL1A, EFNB2, SPRR1A, ROBO1 and SOCS3 were the significant hub genes associated with both mRNA expression and overall survival. IL1A, ROBO1, and SOCS3 were found to be downregulated whereas EFNB2 and SPRR1A were found to be upregulated in our study. However, using UALCAN, we found that high expression of IL1A, EFNB2, SOCS3 negatively affects overall survival whereas high expression of SPRR1A and ROBO1 positively affects overall survival. Protein level for EFNB2 and SPRR1A expression was significant in tumor HNC tissue as compared to normal HNC tissue. EFNB2 was found to be a key regulator of CTX resistance among HNC patients. Targeting EFNB2 and associated PPI circuits might improve the response rate to CTX. Thus, EFNB2 has potential to be theranostic marker for CTX resistance.

Abstract
BACKGROUND Plasma cell leukemia (PCL) is one of the rare cancer which is characterized by the uncontrolled proliferation of plasma cells in peripheral blood and bone marrow. The aggressive behavior of the disease and high mortality rate among PCL patients makes it a thirst area to be explored. METHODS The dataset for PCL was obtained from the GEO database and was analyzed using GEO2R for differentially expressed genes. Further, the functional enrichment analysis was carried out for DEGs using DAVID. The protein-protein interactions (PPI) for DEGs were obtained using STRING 11.5 and were analyzed in Cytoscape 3.7.2. to obtain the key hub genes. These key hub genes were investigated for their interaction with suitable drug candidates using DGIdb, DrugMAP, and Schrodinger's version 2022-1. RESULTS Out of the total of 104 DEGs, 39 genes were up-regulated whereas 65 genes were down-regulated. A total of 11 biological processes, 2 cellular components, and 5 molecular functions were enriched along with the 7 KEGG pathways for the DEGs. Further, a total of 11 hub genes were obtained from the PPI of DEGs of which TP53, MAPK1, SOCS1, MBD3, and YES1 were the key hub genes. Oxaliplatin, mitoxantrone, and ponatinib were found to have the highest binding affinity towards the p53, MAPK1, and YES1 proteins respectively. CONCLUSION TP53, MAPK1, SOCS1, MBD3, and YES1 are the signature hub genes that might be responsible for the aggressive prognosis of PCL leading to poor survival rate. However, p53, MAPK1, and YES1 can be targeted with oxaliplatin, mitoxantrone, and ponatinib.

Abstract
INTRODUCTION H5N1 is a highly pathogenic avian influenza virus that can infect humans and has an estimated fatality rate of 53%. As shown by the current situation of the COVID-19 pandemic, emerging and re-emerging viruses such as H5N1 have the potential to cause another pandemic. Thus, this study outlined the hub genes and pathways associated with H5N1 infection in humans. METHODS The genes associated with H5N1 infection in humans were retrieved from the NCBI Gene database using "H5N1 virus infection" as the keyword. The genes obtained were investigated for protein-protein interaction (PPI) using STRING version 11.5 and studied for functional enrichment analysis using DAVID 2021. Further, the PPI network was visualised and analysed using Cytoscape 3.7.2, and the hub genes were obtained using the local topological analysis method of the cytoHubba plugin. RESULTS A total of 39 genes associated with H5N1 infection in humans significantly interacted with each other, forming a PPI network with 38 nodes and 149 edges modulating 74 KEGG pathways, 76 biological processes, 13 cellular components, and 22 molecular functions. Further, the PPI network analysis revealed that 33 nodes interacted, forming 1056 shortest paths at 0.282 network density, along with a 1.947 characteristic path length. The local topological analysis predicted IFNA1, IRF3, CXCL8, CXCL10, IFNB1, and CHUK as the critical hub genes in human H5N1 infection. CONCLUSION The hub genes associated with the H5N1 infection and their pathways could serve as diagnostic, prognostic, and therapeutic targets for H5N1 infection among humans.

Abstract
BACKGROUND Transfusion-associated graft versus host disease (TA-GVHD) is often underreported. There may also be lapses in TA-GVHD prevention practices due to lack of revision of some of the existing clinical guidelines as well as limited audits on practices of blood component irradiation. This study was undertaken to highlight these shortcomings, and generate data for development of institutional guidelines. METHODS/MATERIALS Study cohort was selected from patients requiring transfusion support during June 2019 to May 2020. Transfusion history of these patients were followed, both retrospectively and prospectively till July 2021. Transfusion requisitions were categorized as IR (with request for irradiation) or NIR (with no request for irradiation) and justified or unjustified according to published international guidelines. RESULTS Total 6963 requisitions for cellular blood components were received from 255 patients included in the study cohort. Of these, 3690 (54.9 %) were IR requisitions, while remaining 3029 (45.1 %) requisitions were NIR. Overall, 4242 (63.1 %) requisition were justified for their irradiation status as per published guidelines and 1595 (23.8 %) were found to be Unjustified while justification could not be assessed for remaining 882 (13.1 %) of the requisitions. The highest proportion of Unjustified demands in NIR requisitions was observed in patients with Severe Aplastic anemia (59.4 %). CONCLUSION Many units were unnecessarily irradiated (7.7 %) while irradiation was missed in 16 % of the requisitions included in analysis which may be attributed to lack of institutional guidelines. We recommend that every centre should adopt a published well-researched guideline including amendments based on review of practices at their center.

Abstract
BACKGROUND Cisplatin resistance is one of the major contributors to the poor survival rate among head and neck cancer (HNC) patients. Focusing on the protein-protein interaction rather than a single protein could provide a better understanding of drug resistance. Thus, this study aimed to identify hub genes in a complex network of cisplatin resistance associated genes in HNC chemotherapy via a series of bioinformatic tools. METHODS The genes involved in cisplatin resistance were retrieved from the NCBI gene database using "head and neck cancer" and "cisplatin resistance" as key words. The human genes retrieved were analyzed for their interactions and enriched using the STRING database. The interaction between KEGG pathways and genes was visualized in Cytoscape 3.7.2. Further, the hub gene was identified using the Cytohubba plugin of Cytoscape and validated using UALCAN and Human Protein Atlas database. Validated genes were investigated for the drug-gene interaction using the DGIbd database. RESULTS Out of 137 genes obtained using key words, 133 were associated with cisplatin resistance in the human species. A total of 150 KEGG pathways, 82 cellular components, 123 molecular functions, and 1752 biological processes were modulated on enrichment analysis. Out of 37 hub genes, CCND1, AXL, CDKN2A, TERT, and EXH2 genes were found to have significant (p < 0.05) mRNA expression and effect on overall survival whereas protein expression was found to be positive for all the significant genes except TERT. Thus, they can be targeted with palbociclib, methotrexate, bortezomib and fluorouracil, sorafenib, dasatinib, carboplatin, paclitaxel, gemcitabine, imatinib, doxorubicin, and vorinostat. CONCLUSION As the pathogenesis of head and neck cancer is complex, targeting hub genes and associated pathways involved in cisplatin resistance could bring a milestone change in the drug discovery and management of drug resistance which might uplift overall survival among HNC patients.

Abstract
Head and neck cancer (HNC) is third highest prevalent cancer among Indian which constitutes about 25-30% of all the cancer in India. Further, out-of-pocket expenditure (OOPE) covers around 67% of total healthcare expenditure and direct medical cost is key factor responsible for raised OOPE in India. Thus, we aimed to quantify total direct medical cost and OOPE associated with HNC management among HNC patients using "Ayushman Bharat Arogya Karnataka scheme" (ABArK scheme). A retrospective study was conducted for the duration of 6 months to collect the data related to total direct medical cost, coverage of "ABArK Scheme" and OOPE of past 2 years of HNC patients. The data of HNC patients above 18 years of age utilizing "ABArK scheme" were included in the study whereas data of patients utilizing other healthcare schemes and incomplete data on target schemes were excluded. A total of 196 patients (54.1%) utilized the "ABArK Scheme" out of 362 HNC patients treated in past 2 years. Among 196 patients, males (76.5%) were predominant over females (23.5%) with the mean age of 53.60 ± 11.58 years. We found that INR 17,370,279 as the total direct medical expenditure for the management of HNC patients of which around 87.465% was covered by "ABArK Scheme" minimizing the OOPE up to INR 3,297,970. Thus, Introduction and implementation of novel healthcare policies like "ABArK Scheme" can counteract financial burden of cancer management by significantly reducing OOPE which could be milestone achievement for the low-middle income countries like India.

Abstract
Introduction: Pemphigus Vulgaris is a rare, noncommunicable, non-hereditary fatal autoimmune dermatological manifestation in which a painful blister initiates from the oral cavity. PRIDE complex stands for Papulopustules or paronychia, regulatory abnormality of hair and nails, itching, and dryness due to inhibition of EGFR. Both of these mucocutaneous manifestations are rare and are often caused by drugs. Case report: Our case reports 53-year-old patient presented with multiple crusted plaques, multiple hyperpigmented macules to patches, Solitary fluid-filled lesions on several parts of the body, and numerous erosions positive over buccal mucosa on initial follow up which was diagnosed as Pemphigus Vulgaris with PRIDE complex induced by Gefitinib. Management and outcome: The patient was treated with almost all possible treatment options, i.e., both steroids plus adjuvant therapy for pemphigus and antihistaminic, antibiotics, moisturizer, and lotions for PRIDE complex. The patient was initially admitted for infusion of the first dose of rituximab and later for management of flare-up condition and infusion of the second dose of rituximab infusion. Discussion: The complexity of the management of Pemphigus Vulgaris and PRIDE complex demands adequate monitoring of the patient's anti-cancerous therapy by clinical pharmacists, which can impact the clinical outcomes by providing pharmaceutical care and minimize the economic burden.

Abstract
Introduction: Incidence of stroke is more frequently found among the elderly who are mostly dealing with co-morbidities and polypharmacy, were found to be significant in high risk of potential Drug-drug Interactions (pDDIs). Aim: To identify potential drug-drug interactions in ischaemic stroke patients. Materials and Methods: This retrospective study was conducted in the General Medicine Department at Justice KS Hegde Charitable Hospital, Mangaluru, Karnataka, India, from January 2018 to August 2020. All the stroke patient’s data were collected based on the inclusion criterion. Prescriptions were obtained from the case sheets and the pDDIs were identified using UpToDate software. Results: The mean age of the study population (N=350) was found to be 61.07±11.460 years, The incidence of stroke was high in males (66%) than in females (34%) from the total of 350 patients. The prescribing patterns were antiplatelet single (69.4%) and fixed-dose combination (1.42%), anticoagulants (11.14%), antihypertensive agents (63.42%), followed by lipidlowering agents (65.14%) as single and fixed dose combinations (0.85%), gastrointestinal agents (70.57%). The class prescribed the most was antiplatelet agents (aspirin 61.4%). The total number of 402 pDDIs were found among 350 patients. Based on the Lexi-Interact® severity scale moderate interactions were the most commonly found then followed by the major and minor with 301 (74.87%), 66 (16.41%) and 35 (8.70%) respectively. The most frequent interaction found were clopidogrel with pantoprazole, and atorvastatin with clopidogrel with same incidence of in 44 (12.57%) patients. Conclusion: The majority of the interaction was found to be moderate interactions which were followed by major and minor interactions. The pDDIs mostly occurred among the antiplatelet agents, gastro-intestinal agents and antihypertensives.

Abstract
BACKGROUND AND AIMS The pharmacotherapy of diabetes mellitus has a colossal economic burden, which demands cost-effective therapy, as the patients have to be on treatment lifelong. Thus, our study aimed to study cost variation and effectiveness analysis among type 2 diabetic patients. METHODOLOGY We conducted ambi-spective research for the adult type 2 diabetes patients who underwent substitution of branded anti-diabetic therapy with the generic alternative from "Jan Aushadhi" for more than one month and were not using any other anti-diabetic medicines. RESULTS Among the monotherapy, glimepiride (2500%) and vildagliptin (20%) were found to have wide and narrow percentage cost variation respectively whereas, metformin Hcl 500 mg plus voglibose 0.2 mg was estimated to have the highest (891.7%), and teneligliptin 20 mg plus metformin 500 mg with the lowest (137.29%) cost variation in case of combined therapy. Similarly, generic substitutions were cost-effective in most patients, whereas the increased cost of brand drugs didn't justify its effectiveness. There was no significant difference between glycated hemoglobin (HbA1c) of brand and generic anti-diabetic drugs (t = 0.774, p = 0.22). CONCLUSION The adaptation of generic drugs can significantly reduce the economic burden of treatment. Thus, healthcare professionals should promote generic medicines by prescribing & dispensing generic drugs and erasing misconceptions prevailing among patients.

Abstract
Background:
Fixed drug eruption (FDE) is an erythematous cutaneous patch caused by
certain drugs through activation of immunologic reactions in the body. The onset of FDE is 30 minutes
to 8 hours and is estimated to occur in upto 16-21% of all cutaneous reactions. The irrational
combination of fluoroquinolones and nitroimidazole is the most prescribed drug for diarrhea in India,
and the drug is found to cause FDE either individually or in combination. Cross sensitivity is
the major issue associated with Fluoroquinolones and nitroimidazole.
Case repor:
Our case is of a 45-year-old male who developed FDE due to a combination product
of ofloxacin and ornidazole with past FDE history due to a combination product of norfloxacin and
tinidazole. The patient presented with erythematous patches all over the body, swollen lips, mucosal
erosion over the buccal cavity, and glans penis.
Discussion:
The patient was successively treated after the withdrawal of the culprit drug with oral
Antihistamines, corticosteroids, and other topical creams and gels, which correlates with the standard
management of FDE.
Conclusion:
Proper prescribing knowledge, documentation of drug allergies, and educating patient
about allergic reaction play vital role to prevent future drug related problems.

Abstract
ABO incompatibility is the most common cause of immune hemolytic disease of the fetus and newborn (HDFN). The American Academy of Pediatrics lists blood group incompatibility as one of the major risk factors for severe hyperbilirubinemia in newborns. We have estimated the risk of ABO HDFN to determine the need for its routine screening. Blood group data from all blood donors who donated in the last 10 years were collected and analyzed. The population prevalence of ABO blood group genes using the phenotype data of blood donors was estimated. This information was further used to calculate an incidence of ABO HDFN requiring intervention in the population. ABO blood group typing was analyzed in 425,743 blood donors. The ABO phenotypes of A, B, O, and AB were 22.48, 36.73, 31.59, and 9.2 percent, respectively. The gene frequencies were 0.1733, 0.2647, and 0.5620 for A, B, and O, respectively. It was estimated that 13.84 percent of group O women would give birth to a non-group O baby and that approximately 2.77 percent of deliveries would likely have ABO HDFN in the study population. In India, the estimated risk of ABO HDFN is 2.9 percent, with a daily 2196 babies at risk of ABO HDFN requiring intervention. This analysis estimates the overall burden of ABO HDFN in the population, which could aid in the decision-making of policymakers, physicians, and community health practitioners to improve neonatal care.

Abstract
BACKGROUND The anecdotal burden of morbidity secondary to motorbike accidents is thought to enormous by personnel involved in trauma care. The objective of the present study is to ascertain patterns and association of injuries and causes of mortality in a cohort of motorbike accident victims. METHODS A retrospective chart review of 1337 motorbike accident admissions B and B Hospital in Kathmandu between January 2009 and December 2010 was undertaken. RESULTS Majority of victims were between 20 to 50 years [1230 (92%) males]. Lower extremity injuries comprised on 816 (61% of total admissions). Tibia fractures were the most common injury in isolation, multiple injury, as well as polytrauma, and a vast majority of these were open fractures. Multiple injuries were seen in 82 (6.1%) patients and 33 (2.5% of Total) patients were polytraumatized. An amputation was necessary in 16 (1.2%) patients and emergent fasciotomy for compartment syndrome was necessary in 23 (1.7%) cases of tibia fractures and 39 (2.2%) of foot and ankle injuries. A floating joint injury was present in 24 (1.8%) patients.. A fat embolism syndrome (FES) was diagnosed in 8 (0.6%) patients. The overall mortality was 0.45% (6 patients). CONCLUSIONS Motorbike accident is an important cause of morbidity and mortality in Kathmandu, and often involves a very productive age group. There is an imminent need to address this public health problem.

Abstract
Synovial chondromatosis is not so rare intra-articular condition secondary to synovial metaplasia, that affects the knee joint. Extra-articular synovial chondromatosis however is an extremely rare condition that usually involves the synovial sheath or bursa of the foot or hand. We present two cases of synovial chondromatosis, one intra and one extra-articular. The first case was a 25 year old lady who presented with pain, swelling and restricted range of motion of left knee and was found to have an intra-articular synovial chondromatosis which was treated successfully by joint debridement. The second case was that of a 22 year old man who presented with right knee pain and was diagnosed to have an extra-articular synovial chondromatosis of his right medial hamstring tendon sheath, excision of which resulted in complete relief of symptoms.

Abstract
Autoimmune hemolytic anemia (AIHA) is not an uncommon clinical disorder and requires advanced, efficient immunohematological and transfusion support. Many AIHA patients have underlying disorder and therefore, it is incumbent upon the clinician to investigate these patients in detail, as the underlying condition can be of a serious nature such as lymphoproliferative disorder or connective tissue disorder. Despite advances in transfusion medicine, simple immunohematological test such as direct antiglobulin test (DAT) still remains the diagnostic hallmark of AIHA. The sensitive gel technology has enabled the immunohematologist not only to diagnose serologically such patients, but also to characterize red cell bound autoantibodies with regard to their class, subclass and titer in a rapid and simplified way. Detailed characterization of autoantibodies is important, as there is a relationship between in vivo hemolysis and strength of DAT; red cell bound multiple immunoglobulins, immunoglobulin G subclass and titer. Transfusing AIHA patient is a challenge to the immunohematologist as it is encountered with difficulties in ABO grouping and cross matching requiring specialized serological tests such as alloadsorption or autoadsorption. At times, it may be almost impossible to find a fully matched unit to transfuse these patients. However, transfusion should not be withheld in a critically ill patient even in the absence of compatible blood. The “best match” or “least incompatible units” can be transfused to such patients under close supervision without any serious side-effects. All blood banks should have the facilities to perform the necessary investigations required to issue “best match” packed red blood cells in AIHA. Specialized techniques such as elution and adsorption, which at times are helpful in enhancing blood safety in AIHA should be established in all transfusion services.

Abstract
BACKGROUND As part of ongoing efforts to improve transfusion safety, an error reporting system was implemented in our hospital-based transfusion medicine unit at a tertiary care medical institute. This system is based on Medical Event Reporting System-Transfusion Medicine (MERS-TM) and collects data on all near miss, no harm, and misadventures related to the transfusion process. Root cause analyses of one such innocuous appearing error demonstrate how weaknesses in the system can be identified to make necessary changes to achieve transfusion safety. STUDY DESIGN AND METHODS The reported error was investigated, classified, coded, and analyzed using MERS-TM prototype, modified and adopted for our institute. RESULTS The consequent error was a "mistransfusion" but a "no-harm event" as the transfused unit was of the same blood group as the patient. It was a high event severity level error (level 1). Multiple errors preceded the final error at various functional locations in the transfusion process. Human, organizational, and patient-related factors were identified as root causes and corrective actions were initiated to prevent future occurrences. CONCLUSION This case illustrates the usefulness of having an error reporting system in hospitals to highlight human and system failures associated with transfusion that may otherwise go unnoticed. Areas can be identified where resources need to be targeted to improve patient safety.

Abstract
BACKGROUND & OBJECTIVE India has a high prevalence of HIV-1, hapatitis C and B virus (HCV and HBV) in the blood donors but has yet to implement nucleic acid testing (NAT) in blood screening. We undertook a multicentre evaluation of blood donor testing by NAT for simultaneous detection of HIV-1, HBV and HCV in a single tube and also to determine the feasibility of NAT implementation in India's low volume setting. METHODS A total of 12,224 unlinked samples along with their serological results were obtained from representative eight blood banks in India and were individually manually tested by the Procleix Ultrio Assay (Chiron Corp. Emeryville, CA) for simultaneous detection of HIV-1, HCV, and HBV. RESULTS Of the 12,224 samples tested, 209 (1.71%) were seroreactive. One hundred thirty three samples (1.09%) were reactive by Ultrio assay, 84 samples were seroreactive but NAT non reactive. There were eight NAT yield cases: 1 HIV, 1 HIV-HCV co-infection, and 6 HBV. INTERPRETATION & CONCLUSION Our observed NAT yield for all three viruses was 1 in 1528 (0.065%). We estimate NAT could interdict 3272 infectious donations a year among our approximate 5 million annual donations.

Abstract
Perforation of the gallbladder is an uncommon complication of acute cholecystitis that is associated with relatively high mortality. Symptoms and clinical signs can be indistinguishable from those of uncomplicated acute cholecystitis, leading to delayed diagnosis. We reviewed the clinical and imaging findings in 17 patients with gallbladder perforation confirmed at surgery.

Abstract
Recently, the irradiation of cellular blood components has received increased attention. Normal red blood cells (RBC) when subjected to gamma irradiation show increase in haemolysis and increased storage lesions. Glucose 6 phosphate dehydrogenase (G6PD) deficient blood is lacking in anti-oxidant properties which protect the RBC membrane and therefore when subjected to gamma irradiation, it may lead to increased haemolysis. In this study, 500 healthy non-remunerated blood donors were screened for G6PD deficiency. About 350 ml of whole blood was collected from 10 G6PD deficient donors (cases) and 10 units were collected from donors who were not deficient for G6PD (controls). All units were subjected to gamma irradiation of 25 Gy by a self contained gamma cell irradiator (Nordion Canada) on day 0 and then stored at 4 degrees C. Sampling was done from these cases and controls on day 0, 7, 14 and 21. Estimation of free plasma hemoglobin (Hb), free plasma potassium (K) and lactate dehydrogenase (LDH) was performed. It was found that there were no significant changes between the cases and controls in any of the parameters assessed, although the values for all the parameters were higher in case group at the end of storage period, these differences were not statistically significant.

Abstract
17 cases reviewed prospectively over a period of 4 months highlight the varied appearance of blood-fluid levels in intracranial cystic lesions of different aetiologies; a finding which has not featured significantly in the medical literature. Four types of intracranial cysts demonstrating blood-fluid levels have been categorised according to the nature of the pathology, i.e. primary neoplasms of the brain, metastatic deposits to the brain in cases of extraneural malignancies, lesions of vascular aetiology and intraparenchymal bleeds secondary to trauma. The group of four primary intracranial neoplasms lists an oligodendroglioma, a recurrent tumour in a case of Von Hippel-Lindau syndrome, a Grade 3 astrocytoma and an acoustic schwannoma. Four cases of metastatic deposits to the brain were each secondary to primary malignant neoplasms of the breast, liver, ovary and lung. Of seven cases of a vascular aetiology, three resulted from arterial infarction, two from hypertension and one each from venous infarction and following anticoagulant therapy. Intracranial cysts within tumours have been postulated to occur secondary to a breakdown of the blood-brain barrier (BBB) rather than as a result of tumoural degeneration, as was thought probable earlier.

Abstract
Gel tests are now available for the determination of immunoglobulin classes and subclasses and complement fractions coating RBCs. These tests simplified serologic characterization of autoantibodies in various autoimmune diseases. The aim of this study was to evaluate the use of gel cards in the serologic characterization of autoantibody with regard to the immunoglobulin classes, complement fractions, and IgG subclasses, and the influence of these characteristics on hemolysis. Gel cards were used to characterize the RBC-bound autoantibodies in 66 DAT-positive patients. Hematologic and biochemical parameters such as Hb, reticulocyte count, serum bilirubin, and serum LDH were obtained from the patient files. Of the 49 patients carrying IgG on their RBCs, 21 (42.8%) were suffering from connective tissue disorders and another 16 patients (32.7%) had autoimmune hemolytic anemia. A total of 19 of these 49 patients had evidence of hemolysis. Thirteen of the 17 patients (76.5%) whose RBCs were coated with more than one type of immunoglobulin and complement were experiencing hemolysis (p < 0.05). Seventy-five percent (21 of 28) of patients having IgG1, IgG3, or both on their RBCs showed hemolysis (p < 0.05). Thus, it is important to serologically characterize autoantibodies in autoimmune disorders to effectively predict the prognosis and disease outcome. This characterization can be performed effectively with the gel test, which can be introduced in blood centers as a replacement to the conventional tube technique.

Abstract
Platelet recovery in the recipient is influenced by the transfused dose of platelets, which in turn is dependent on the quality of single donor platelets (SDPs) in terms of platelet yield. Various donor factors such as predonation platelet count and Hemoglobin (Hb) concentration affect the platelet yield. A total of 61 plateletpheresis procedures performed on intermittent flow cell separator (MCS3p, Hemonetics) were evaluated for platelet yield. A relationship between predonation platelet count and Hb concentration with yield of platelets was studied using Pearson Correlation. The mean platelet yield was 2.9 +/- 0.64 x 10(11). While a direct relationship was observed between predonation platelet count and yield (r = 0.51, P < 0.001), no such correlation was noticed with donor Hb concentration (r = -0.05, P > 0.005). The yield was > or =3 x 10(11) in >80% of procedures when the predonation platelet count was > or =250 x 10(3)/mm. Optimization of platelet yield, which is influenced by predonation platelet count, is an emerging issue in blood transfusion services. However, further studies in this regard are needed using more advanced cell separators.

Abstract
BACKGROUND & OBJECTIVE The irradiation of blood components has received increased attention due to increasing categories of patients eligible to receive such blood to prevent transfusion-associated graft versus host disease. Irradiation leads to enhancement of storage lesions, which could have deleterious effects when such blood is transfused. The aim of the present study was to assess the biochemical changes during conventional preservation of irradiated and non-irradiated whole blood. METHODS Ten units of whole blood were taken from healthy donors and divided into two parts. One aliquot was subjected to gamma irradiation and then stored under conventional blood banking conditions. Sampling was done from these irradiated and non-irradiated blood bags and tests for free plasma haemoglobin, plasma potassium and lactate dehydrogenase (LDH) were performed. RESULTS A progressive increase in the mean values of plasma Hb, K+ and LDH was seen in both the groups. The increase was statistically significant. INTERPRETATION & CONCLUSION Our findings indicated that the gamma irradiation of blood resulted in increased plasma haemoglobin, potassium and LDH. These biochemical changes might not have clinical significance when irradiated blood is transfused to a select group of patients. There is a need for further in vivo studies to follow up the consequences of transfusion of irradiated blood in patients.

Abstract
The pharmacokinetics, urinary excretion and dosage regimen of diminazene were investigated in crossbred male calves following a single intramuscular dose (3.5 mg x kg-1). Following intramuscular administration, the pharmacokinetics of diminazene was described with a one-compartment open model. The absorption rate constant and absorption half-life were 9.86 +/- 3.06 h-1 and 0.121 +/- 0.40 h, respectively. The value of elimination half-life was 107.5 +/- 8.50 h. The apparent volume of distribution was 0.74 +/- 0.07 L x kg-1. Systemic availability following intramuscular administration was 91.7%. Approximately 65% of the administered dose of diminazene was eliminated in the urine within 24 h of its intramuscular administration. Diminazene was bound to plasma proteins to the extent of approximately 32%. The satisfactory intramuscular dosage regimen of diminazene for calves would be 2.24 mg x kg-1 followed by 1.5 mg x kg-1 at 7 days.

Abstract
BACKGROUND/AIMS Previous cross-sectional data suggested that chronic hepatitis B viral (HBV) infections in the Canadian Inuit were inactive. The aim of this study was to confirm these findings and document the prevalence of the subsequently described "pre-core mutant" variant of HBV in this population. METHODS We obtained sera from residents of five remote Canadian Inuit communities. Residents were selected if they were known to be hepatitis B surface antigen (HBsAg) positive or had a history of liver disease. HBV serology, HBV-DNA, and pre-core mutant testing were performed by commercially available assays, polymerase chain reaction (PCR) and direct sequencing of the viral genome, respectively. RESULTS Sera were obtained from 176/266 (66%) of selected individuals. Thirty-eight (22%) were HBsAg positive and 16 (9.1%) anti-HBs positive. Of HBsAg positive carriers 25/38 (66%) were male as compared to 68/138 (49%) of the remaining individuals (p<0.05). Of 37 HBsAg positive carriers, none were HBeAg positive, 36 (97%) anti-HBe positive and one (3%) HBeAg and anti-HBe negative. Liver enzyme and function tests were normal in all cases. 30/37 (81%) HBsAg positive carriers were HBV-DNA positive and 26/30 (87%) were pre-core mutant positive. CONCLUSION The majority of HBV infections in community-based Canadian Inuit are inactive and the prevalence of pre-core mutant infections is the highest reported to date.

Abstract
The AIDS pandemic has brought into focus the importance of safe blood transfusion. The management of an effective transfusion service is an expensive endeavour even in the most developed countries, and is therefore a monumental challenge for developing countries with limited budgets and other priorities. HIV prevalence in the Indian population has shown a steady rise from 0.5% in 1990 to 1.2% in 1997 with the highest prevalence in cities. When the HIV infection was discovered in India in 1986, the health authorities set up the National AIDS Control Organisation (NACO) with a primary focus on ensuring a safe blood supply. NACO was funded by the World Bank and technically supported by WHO. The supreme Court of India has also taken up the issue of blood safety by banning paid donations by the end of 1997 and established the autonomous National Blood Transfusion Council and the State Transfusion Councils. The Drugs Controller of India and State F.D.A. have issued licences to all blood banks to streamline them after all requirements are met. However, there are a number of blood banks which are operating without licences. While India collects three million units of blood, barely 10% is available as blood components, and only a percentage of the blood is being screened for infectious markers. Nevertheless, there is a general recognition that an improved transfusion service is required in India.

Abstract
The effect of endotoxin-induced fever on the pharmacokinetics and dosage regimen of cefuroxime was investigated in buffalo calves following a single intravenous dose of 10 mg/kg body weight. The fever was induced by intravenous administration of E. coli endotoxin at a dose of 1 microg/kg body weight. The distribution and elimination half-lives were 0.100 h and 1.82 h, respectively, in healthy and 0.109 h and 2.28 h, respectively, in febrile buffalo calves. About 91% of the administered dose was excreted in the urine within 24 h. There was no effect of fever on the plasma protein binding of cefuroxime. The dosage regimen for intravenous administration of cefuroxime may be reduced in febrile conditions but the probability of this was only 0.3.

Abstract
Red blood cell (RBC) transfusions are frequently used in the management of patients with chronic renal failure (CRF) undergoing hemodialysis for dialysis-related anaemia. Consequently, they are subject to all hazards associated with repeated transfusions, such as red cell alloimmunization. A retrospective study was performed to estimate the frequency of alloimmunization against red cell antigens in multitransfused CRF patients. A total of 81 patients (67 males & 14 females) with CRF were studied who received a mean of 8.5 units of RBC matched for ABO & Rh(D) antigens only. Using standard techniques (indirect antiglobulin test, enzyme, polyethylene glycol, and low ionic strength solution), we observed a RBC alloimmunization rate of 9.8% (8/81). Nine alloantibodies were detected in 8 patients, and most (88%) involved antigens in the Rhesus & Kell systems. No correlation was observed with the alloantibody formation & number of units transfused. The calculated risk of 1.3% observed in the present study, suggests that renal failure patients are not at a higher risk of red cell alloimmunization than the general population.

Abstract
Passenger lymphocytes in grafted kidney have been reported to result in autoimmune hemolytic anemia (AIHA) in minor ABO incompatible transplants. We followed up 15 cases of minor ABO incompatible transplants for one year. Two patients developed severe but self-limited auto-immune hemolytic anemia within two weeks of renal transplantation. Both were blood group A and had received a kidney from a group O donor. Preoperative cross-match and antibody screen was negative; however subsequent to the hemolytic episode, group-specific blood was incompatible and patients were transfused with group O, cross-match compatible blood. Serological tests showed positive direct anti-globulin test (DAT) and anti-A was eluted from both cases.

Abstract
A retrospective analysis of records of the deferred donors from 1 October 1992 to 31 December 1993 was performed. Of 14,269 prospective blood donors (13,030 males and 1,239 females), 2,431 (16.4%) donors were disqualified for various reasons: 8.1% of the donors were deferred for non-pathological causes while 91.9% were deferred for medical reasons. The most common cause for non-pathological deferral was volunteers attending below the minimum acceptable age (5.2%). Abnormal findings on physical examination accounted for 57.2% of the deferrals in which low body weight was the most common finding (32.3%) followed by low Hb (18.6%). A past history of jaundice was the leading cause for deferral on medical interview. Numerous prospective donors are currently being deferred based on empirically derived criteria. By developing strategies to identify and rationalize donor selection criteria, the blood transfusion services should be able to decrease unnecessary deferrals.

Abstract
A reverse hybridization test (Inno-LiPA HCV; Innogenetics, N.V., Zwijnaarde, Belgium) was used for typing hepatitis C virus. All 38 samples, typed by PCR with primers from core and NS5 genes, were also genotyped by this test. Of the samples, 33 (87%) had the same subtypes by both assays. The correlations between PCR and Inno-LiPA for individual types were 77% for type I (1a), 90% for type II (1b), 100% for type III (2a), 100% for type IV (2b), and 100% for type V (3a). One of the type III (2a) samples also reacted with type I (1a) probes in the Inno-LiPA test.

Abstract
The case of a 76-year-old white woman with squamous cell carcinoma of the thyroid gland arising in a background of Hashimoto's thyroiditis is presented. Squamous cell carcinoma of the thyroid gland is a very rare and aggressive tumor, and only a few cases are reported as arising in Hashimoto's thyroiditis. Although Hashimoto's thyroiditis alone does not necessarily predispose patients to malignancy, the finding of a prominent nodule in such a patient should suggest the possibility of malignancy, and an aggressive search and treatment regimen, including surgical intervention, should be pursued.

Abstract
We investigated three immunoblot assays (RIBA 3.0 from Chiron, Matrix from Abbott Laboratories, and LiaTek III from Organon Teknika) for the detection of antibody to hepatitis C virus. RIBA 3.0 and Matrix require reactivity to two antigens and LiaTek III requires reactivity to one for a sample to be positive. We tested 80 samples that were positive in repeat enzyme immunoassays by supplemental tests. The results showed that 55, 46, and 28% were reactive by LiaTek III, RIBA 3.0, and Matrix, respectively; 54, 33, and 13% of the samples were indeterminate by Matrix, RIBA 3.0, and LiaTek III, respectively. There were 32, 21, and 16% nonreactive samples by LiaTek III, RIBA 3.0, and Matrix, respectively. Of the samples positive by RIBA 3.0, only 50 and 76% were reactive by Matrix and LiaTek III, respectively. A large number of samples that were indeterminate by RIBA 3.0 were positive by LiaTek III (52%). The core antigen was the most reactive antigen in all three tests (48 to 57%). The NS4 antigen in Matrix (20%) and LiaTek III (16%) was poorly reactive, although it performed better in RIBA 3.0 (45%). The NS5 and E2/NS1 antigens made minor contributions to reactivity. The combinations of the core, NS3, and NS4 antigens produced 77% of the RIBA 3.0 and 100% of the Matrix reactive samples. The results showed a poor correlation among the three tests.

Abstract
We used PCR for hepatitis C virus (HCV) genotyping with type-specific primers from the core and NS5 genes. Type I was predominant in the general population (58% in blood donors) as well as in different risk groups, such as intravenous drug abusers (58%), blood transfusion recipients (64%), hemophiliacs (62%), and patients with HCV chronic liver disease (76%). Types II, III, and IV were less prevalent in Canada, being found in 10.92, 6.72, and 5.88% of the population, respectively. The type II core primer was not type specific and reacted with the majority of our type I HCV samples, suggesting a false-positive dual infection with two different genotypes (I and II). Digestion of these amplified type I and type II products with restriction endonuclease AccI proved to be very useful in the exclusion of false-positive dual type I and type II infections.

Abstract
Of 106 samples positive for antibody to hepatitis C virus (anti-HCV) by first-generation enzyme immunoassay (EIA-1), 63 (59%), 67 (63%) and 43 (41%) were reactive by second-generation EIAs (EIA-2). Among positive EIA-1 samples, 33% were reactive by second-generation recombinant immunoblot assay (RIBA-2). A higher percentage of positive EIA-2 samples, however, were reactive by RIBA-2. In the high-risk group there was a correlation between the EIA-2 and RIBA-2 results. In the low-risk group, however, the correlation was poor except in blood donors, in whom 57% of samples were reactive by EIA-2 and RIBA-2. Results showed that the sensitivity and specificity of EIA-2s has improved although further improvement is desirable.

Abstract
The disposition kinetics and appropriate dosage regimen for kanamycin were investigated in buffalo calves following a single intravenous dose of 10 mg/kg body weight. The distribution and elimination half-lives were 0.12 +/- 0.01 h and 1.94 +/- 0.11 h, respectively. The apparent volume of distribution and total body clearance were 0.2 +/- 0.01 L/kg and 92.9 +/- 3.69 ml/kg/h, respectively. About 74% of the administered dose was excreted in urine in 24 h. A suitable dosage regimen for the intravenous administration of kanamycin was also calculated.

Abstract
The newly developed immunoblot assay, RIBA SIA (recombinant and synthetic polypeptide immunoblot assay), Chiron, Calif., was compared with the commercially available second generation recombinant immunoblot assay (RIBA-2) for the detection of antibody to hepatitis C virus (anti-HCV). The two immunoblot tests were also compared with the polymerase chain reaction (PCR) for the detection of HCV RNA. Ninety-one percent of samples reactive by RIBA-2 were positive for anti-HCV by RIBA SIA. A total of 31% of RIBA-2 indeterminate samples became reactive by RIBA SIA, 24% became non-reactive, and 45% remained the same. Samples reactive by RIBA-2 or SIA from different risk groups, were mostly positive (67-100%) by PCR for HCV RNA. All indeterminate samples from hemophiliacs and intravenous drug users were PCR positive. RIBA SIA is more sensitive and specific than RIBA-2 and correlates well with PCR results.

Abstract
A retrospective analysis of 1140 cases of cancer of oral cavity and oropharynx treated with definitive radiotherapy was carried out with regard to the incidence and precipitating factors of mandibular osteoradionecrosis. 14 cases developed osteoradionecrosis out of which 10 had spontaneous mandibular necrosis and 4 had dental extractions in the area where osteoradionecrosis developed. Amongst the 10 cases of spontaneous osteoradionecrosis, 8 patients received doses of 6500 cGy in 6 1/2 weeks or 7000 cGy in 7 weeks by megavoltage cobalt 60 teletherapy and the remaining two patients received the doses of 6000 cGy in 6 weeks. The aforesaid 4 patients of osteoradionecrosis in the area of dental extractions had received doses of only 6000 cGy in 6 weeks.

Abstract
The effect of ribavirin on fetal Rhesus monkey kidney cells (FRhK-4) acutely or chronically infected with hepatitis A virus was studied. The effect of ribavirin on hepatitis A virus yield as detected by radioimmunoassay in acutely infected FRhK-4 cells was dependent on hepatitis A virus inoculum dose. Treatment with 100 μg/mL ribavirin completely inhibited hepatitis A virus growth in cultures infected with 100 to 800 tissue culture infectious dose 50 (TCID(50)) hepatitis A virus, but inocula of 800 to 1600 TCID(50) resulted in limited production of virus. The effect was time dependent and required more than 96 h of treatment to inhibit the virus completely. Ribavirin was less effective in treating cells persistently infected with hepatitis A virus, although there was significant inhibition of hepatitis A virus (82%) in persistently infected cells as well. Ribavirin had some inhibitory effect on cell growth; treatment with 25, 50 or 100 μg/mL ribavirin reduced cell growth by approximately 0, 20 and 40%, respectively.

Abstract
Hepatitis C virus (HCV) antibodies were detected in 85.9% of the samples by commercial enzyme immunoassay (EIA) kits. Most EIA-positive samples were reactive (80%) by the RIBA HCV test (Ortho Diagnostics). Samples with optical density values greater than or equal to 2.0 were mostly reactive (87%) by RIBA HCV test, in contrast to those with values less than or equal to 1.0 (6.6%). Samples which were indeterminate by the RIBA HCV test were positive (88.4%) by HCV neutralization EIA (Abbott Laboratories), along with 29.4% of samples which were nonreactive by the RIBA HCV test.

Abstract
Samples reactive by first-generation recombinant immunoblot assay (RIBA) to detect antibody to hepatitis C virus (anti-HCV) (RIBA-1 [Chiron, Calif.]) remained reactive by a second-generation test (RIBA-2) for HCV antibodies. A total of 75% of specimens indeterminate by RIBA-1 became reactive, 12.5% were nonreactive, and 12.5% remained indeterminate by RIBA-2. Among RIBA-1-nonreactive specimens, 12.0% became positive and 5.1% became indeterminate by RIBA-2. The antigens c33c and c22-3 have increased the sensitivity of RIBA-2.
