Abstract
Background Nursing professionals, comprising the largest workforce engaged in the primary healthcare system, play a pivotal role in addressing population health needs. However, gaps in the training of nurses and midwives in lower-middle-income countries may undermine their performance and necessary skill development for fulfilling key population health needs. Substantial challenges exist in improving the regular curricular and refresher training of diplomate nurses and midwives working in primary care facilities and supporting both clinical care and health promotion functions. The study objective was to conduct a gap analysis in the present nursing curriculum and training profile of general duty midwives working in urban primary health facilities and understand their expectations and preferences from the planned refresher training course. Methods We conducted a qualitative explorative study among General Nursing midwives (GNMs) working in urban primary health facilities in the Gurugram district of Haryana, India to conduct a gap analysis in their present curriculum and training preferences. Results A total of 17 nurses with a mean (SD) age of 33.52 (4.75) years and an average nursing work experience of 5.35 (0.56) years were interviewed in-depth. Lack of practical applicability, complex study material, inexperienced tutors, and weak English language comprehension were key barriers in the existing nursing curriculum. The nurses expressed willingness to participate in refresher training with varied expectations, although there existed a distinct preference for short, flexible, and blended online-offline modes of training. Conclusions Strengthening GNM nursing education should be prioritized in Indian health settings with the focus on improving student comprehension through vernacular instruction when feasible, and capacity building of tutors, with avenues for continued training and education. There is also a need for strengthening the curriculum related to key emergent public health challenges related to non-communicable diseases and mental health, as also skills for client and patient counseling and communication.

Abstract
Purpose Outcome of topography-guided excimer laser ablation in conjunction with accelerated, high-fluence cross-linking in corneal ecstatic disease using the NIDEK CXIII equipped with CATz algorithm from the FinalFit software-"Bharat Protocol." Methods Retrospective case record review of 30 eyes of 17 patients of stage 1-3 keratoconus who underwent the procedure was performed. Data collected were for visual acuity, distortion-induced eye pain, and keratometry. Pachymetry, lower order and higher order aberrations, spherical aberrations, and topographic cylinder were documented from by Scheimpflug imaging (Pentacam 70700: Oculus, Wetzlar, Germany). Results At a minimum follow-up of 6 months (range 6.2-13 months), there was significant improvement in UCVA (P < 0.00001), BCVA (P = 0.0061), decrease in Kmax (P = 0.0349), Ksteep (P < 0.0411), Kflat (P = 0.0099), and pachymetry (P = 0.0001). Significant improvement was also seen in distortion-induced eye pain (27/30 to 2/30; P < 0.00001). A more than two-line improvement in UCVA and BCVA was seen in 23/30 and 17/30 cases, respectively. Ectasia was stabilized in all cases at the last follow-up, and no complications were seen. Conclusions The "Bharat" Protocol to arrest keratectasia progression and improve corneal regularity is a safe and efficacious alternative as a keratoconus management option. This is the first such study on Nidek Platform for the same.

Abstract
INTRODUCTION Low birth weight (LBW) is an important public health indicator extensively linked to infant and child mortality, especially in lower-middle-income countries (LMICs). Globally, 15.5% of all infants are born with LBW while 95% of these occur in LMICs. This study aims to examine the prevalence and determinants of LBW in India. METHODS Data were obtained from the fifth National Family Health Survey (NFHS) round conducted during 2019-2021. The study sample included women aged 15-49 years who had a singleton pregnancy in the five years preceding the survey (N=175,240). A bivariate analysis was carried out and a logistic regression model was fitted to assess the maternal determinants affecting the birth weight among newborns. RESULTS A total of 175,240 mothers were included in the present study. The proportion of newborns with LBW was 17.29% (n=26366, 95% confidence interval [CI] 17.01, 17.57), of which 6% (n=1450, 95% CI 5.61, 6.41) had very low birth weight (less than 1500 g). An increase in the education level of women or wealth index also resulted in significantly reduced odds of LBW in the newborn. However, the number of antenatal care (ANC) visits lacked any statistically significant association with the odds of having a newborn with LBW. CONCLUSIONS The burden of LBW in India in recent years has remained stable despite impressive economic growth and increased public health spending on food security and nutritional supplementation. Strengthening the quality of ANC services for pregnant women with a focus on sensitization and awareness generation for improving maternal nutrition requires high prioritization.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH) has been well characterised and codified through the development of diagnostic criteria. These criteria have been adapted and simplified and are widely used in clinical practice. However, there is a need to update and precisely define the criteria for both treatment response and treatment. METHODS A systematic review was performed and a modified Delphi consensus process was used to identify and redefine the response criteria in autoimmune hepatitis. RESULTS The consensus process initiated by the International Autoimmune Hepatitis Group proposes that the term 'complete biochemical response' defined as 'normalization of serum transaminases and IgG below the upper limit of normal' be adopted to include a time point at 6 months after initiation of treatment. An insufficient response by 6 months was a failure to meet the above definition. Non-response was defined as '<50% decrease of serum transaminases within 4 weeks after initiation of treatment'. Remission is defined as liver histology with a Hepatitis Activity Index <4/18. Intolerance to treatment was agreed to stand for 'any adverse event possibly related to treatment leading to potential drug discontinuation'. CONCLUSIONS These definitions provide a simple and reproducible framework to define treatment response and non-response, irrespective of the therapeutic intervention. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable inter-study comparisons. Future prospective database studies are needed to validate these endpoints. LAY SUMMARY Consensus among international experts on response criteria and endpoints in autoimmune hepatitis is lacking. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable the comparison of results between clinical trials. Therefore, the International Autoimmune Hepatitis Group (IAIHG) herein presents a statement on 5 agreed response criteria and endpoints: complete biochemical response, insufficient response, non-response, remission, and intolerance to treatment, which can be used to guide future reporting.

Abstract
Condylar hyperplasia (CH) of the mandible is a rare developmental disorder that results in enlargement of the condyle. It is predominant in females, mostly unilateral and self-limiting. This report presents a case of a 35-year-old female patient with unilateral condylar hyperplasia with an increase in vertical height of mandibular ramus of the affected side. After initial radiographic evaluation, the asymmetry index using a panoramic radiograph was determined and also analyzed using cone-beam computed tomography (CBCT). Condylar dimensions in all the planes were measured for both sides using CBCT. This case report emphasizes the importance of CBCT and its role in the diagnosis and assessment of mandibular condylar hyperplasia.

Abstract
Engineered three-dimensional (3D) in vitro and ex vivo neural tissues, also known
as “mini brains and spinal cords in a dish,” can be derived from different types
of human stem cells via several differentiation protocols. In general, human
mini brains are micro-scale physiological systems consisting of mixed
populations of neural progenitor cells, glial cells, and neurons that may
represent key features of human brain anatomy and function. To date, these
specialized 3D tissue structures can be characterized into spheroids, organoids,
assembloids, organ-on-a-chip and their various combinations based on generation
procedures and cellular components. These 3D CNS models incorporate complex
cell-cell interactions and play an essential role in bridging the gap between
two-dimensional human neuroglial cultures and animal models. Indeed, they
provide an innovative platform for disease modeling and therapeutic cell
replacement, especially shedding light on the potential to realize personalized
medicine for neurological disorders when combined with the revolutionary human
induced pluripotent stem cell technology. In this review, we highlight human 3D
CNS models developed from a variety of experimental strategies, emphasize their
advances and remaining challenges, evaluate their state-of-the-art applications
in recapitulating crucial phenotypic aspects of many CNS diseases, and discuss
the role of contemporary technologies in the prospective improvement of their
composition, consistency, complexity, and maturation.

Abstract
BACKGROUND International Federation of Gynaecology and Obstetrics (FIGO) staging of carcinoma cervix, although essentially clinical, acknowledges the benefits of MRI. The impact of incorporating MRI in staging of cervical cancer and the discordance between clinical-and MRI-based FIGO staging is not well studied, especially in low- and middle-income countries. AIM We aim to study the role and accuracy of MRI in staging carcinoma cervix, its correlation with clinical FIGO and histopathological staging with emphasis on how it can change treatment plan. METHODS Retrospective observational cohort study (n = 193) where MRI details of different staging parameters of the study subjects were compared with clinical FIGO staging and histopathology to assess correlation and agreement between them. Change of clinical FIGO stage and hence treatment plan brought about by incorporating MRI was assessed. RESULTS MRI had a tumor detection rate of 94.3%, overall staging accuracy of 78.3% and very strong correlation with histopathology (Spearman's coefficient of rank correlation, r = 0.886). Clinical FIGO and MRI had agreement only in 52.8% cases (r = 0.61). Incorporating MRI changed the clinical stage in 47.2% patients and subsequently modified primary treatment plan in 23.3%. CONCLUSION MRI is highly accurate in evaluating carcinoma cervix and has good correlation with histopathology. Our data shows low agreement between MRI and clinical FIGO staging. Thus, incorporating MRI in FIGO staging has considerable impact in altering treatment decisions and should be offered to all patients for staging carcinoma cervix.

Abstract
Mutations of the SPAST gene that encodes the microtubule-severing enzyme called spastin are the chief cause of Hereditary Spastic Paraplegia. Growing evidence indicates that pathogenic mutations functionally compromise the spastin protein and endow it with toxic gain-of-function properties. With each of these two factors potentially relevant to disease etiology, the present article discusses possible therapeutic strategies that may ameliorate symptoms in patients suffering from SPAST-based Hereditary Spastic Paraplegia, which is usually termed SPG4-HSP.

Abstract
Antibiotic therapy may have important side effects. Guidelines recommend the administration of specific probiotics to reduce the risk of antibiotic-associated diarrhoea (AAD). The rates and determinants of antibiotics and co-prescription of probiotics in children remain poorly known in Asia-Pacific countries, which are very heterogenous in terms of economic development, health care organization and health policies. A survey among general practitioners (GPs) and paediatricians was performed in seven countries of the Asia-Pacific area (Australia, Japan, Indonesia, India, China, Singapore, and South Korea). Physicians completed an online questionnaire that explored their current habits and the determinants for prescribing antibiotics and probiotics. For the 731 physicians who completed the questionnaire (390 paediatricians and 341 GPs), 37% of all consultations for a child led to the prescription of antibiotics (ranging from 17% in Australia to 47% in India). A large majority of physicians (84%) agreed that antibiotics disrupted gut microbiota and considered probiotics an effective intervention to prevent AAD (68%). However, only 33% co-prescribed probiotics with antibiotics (ranging from 13% in Japan to 60% in South Korea). The main reasons for prescribing probiotics were previous episodes of AAD (61%), presence of diarrhoea (55%), prolonged antibiotic treatment (54%) or amoxicillin-clavulanic acid therapy (54%). Although current local guidelines recommend the use of selected probiotics in children receiving antibiotics in Asia-Pacific area, the rates of antibiotics and probiotics prescription significantly vary among countries and are deeply affected by country-related cultural and organisational issues.

Abstract
Tuberculous adenitis presenting as an isolated cold abscess in the parapharyngeal space is very uncommon and has not been reported in the paediatric age group; presentation as a retropharyngeal abscess, however, is well known. Nine-year-old boy with a progressively increasing swelling on the right side of the neck for 2 months was referred with a clinical diagnosis of neuroblastoma. Surgical exploration of the parapharyngeal space by needle aspiration yielded a cheesy material and Mycobacterium tuberculosis was detected by DNA TB PCR. Tuberculosis should always be considered in the differential diagnosis of a cervical swelling in a child.

Abstract
AIMS The present study was aimed at design of experiments (DoE)- and artificial intelligence-based culture medium optimization for high level extracellular production of a novel recombinant human interferon alpha 2b (huIFNα2b) in glycoengineered Pichia pastoris and its characterization. METHODS AND RESULTS The artificial neural network-genetic algorithm model exhibited improved huIFNα2b production and better predictability compared to response surface methodology. The optimized medium exhibited a fivefold increase in huIFNα2b titre compared to the complex medium. A maximum titre of huIFNα2b (436 mg l-1 ) was achieved using the optimized medium in the bioreactor. Real-time capacitance data from dielectric spectroscopy were utilized to model the growth kinetics with unstructured models. Biological characterization by antiproliferative assay proved that the purified recombinant huIFNα2b was biologically active, exhibiting growth inhibition on breast cancer cell line. CONCLUSIONS Culture medium optimization resulted in enhanced production of huIFNα2b in glycoengineered P. pastoris at both shake flask and bioreactor level. The purified huIFNα2b was found to be N-glycosylated and biologically active. SIGNIFICANCE AND IMPACT OF THE STUDY DoE-based medium optimization strategy significantly improved huIFNα2b production. The antiproliferative activity of huIFNα2b substantiates its potential scope for application in cancer therapy.

Abstract
Context: Tooth plays a pivotal role in the identification of a person when all other remains are ruined by natural or unnatural causes. Dental evidence can contribute to age estimation in forensic dentistry. Estimating the age of an individual with the help of a tooth for identification proves beneficial. Alternating light and dark bands seen on the cementum have been shown to be proportionate to the age of the patient in number. This was done to evaluate the cementum annulation in age determination. Aims: This study aimed to determine the age of an individual using tooth cementum annulation. Materials and Methods: In this study, twenty extracted teeth were collected and all the clinical details of the patient such as age, sex, and chief complaint were recorded. The collected teeth was preserved in formalin overnight and then washed under tap water before they were sectioned. The area selected for counting was observed under 10 × objective of light microscope, and photomicrographs were taken for the counting of the lines. At the time of analysis, the age of the patient was not disclosed to the observer. Statistical Analysis Used: Student's t-test was used for statistical analysis. Results: This study showed the correlation between the actual age of the individual and the estimated age using tooth cementum annulation method and showed significant statistical value. Conclusion: Incremental lines found in cementum can be used for age estimation in forensic dentistry.

Abstract
Aim The aim of the study was to evaluate the serum lipid profile among untreated oral squamous cell carcinoma (OSCC) and oral submucous fibrosis (OSMF) patients. Materials and Methods This study was done in three groups of patients - OSMF, OSCC, and control. There are twenty participants in each group. Calorimetric method using semi-autoanalyzer was used for analyzing the lipid levels (cholesterol, triglycerides [TGL], and high-density lipids [HDL]) after collecting 2 ml of fasting blood from these patients. Low-density lipid [LDL] values were obtained by calculator method. Results There was a significant decrease in serum lipid levels of patients with OSMF and OSCC. Conclusion The decrease in lipid levels in OSMF and OSCC patients is due to its utilization by the cells during the cancer process.

Abstract
PURPOSE To assess the impact of care at foster homes on the health-related quality of life (HRQOL) of children living with HIV (CLHIV), attending a referral ART Centre, and to compare their HRQOL with children living in their own homes. METHODS A cross-sectional study was conducted in 144 CLHIV between 5 and 18 years of age, attending a referral ART Centre in South India to assess their HRQOL using the standard PedsQL™ 4.0 questionnaire. Data were then analysed to compare the HRQOL of children living in foster homes to those children living in their own homes. The child report and the parent proxy-report on the child's HRQOL were also compared to see for any differences in their perspectives. RESULTS 56.25% CLHIV were brought up in different foster homes. In the child's self-report, the mean HRQOL was higher for children living in foster homes [physical score (76.54 ± 12.40), psychosocial score (71.41 ± 12.40) and total score (73.20 ± 11.13)] when compared to children living in their own homes [physical score (75.09 ± 14.76), psychosocial score (70.60 ± 13.48) and total score (72.17 ± 12.00)]. There was no statistically significant difference in the HRQOL between these two groups (p > 0.05). In the parent proxy-report also, there was no statistically significant difference in the HRQOL in all the three scores. The child self-report depicted a significantly higher HRQOL in all the domains compared to the parent proxy-report (p < 0.05). CONCLUSIONS HRQOL of children living in foster homes is at par with the quality of life enjoyed by children living in their own homes. Foster care manages to provide a reasonable HRQOL in CLHIV, and has become an inseparable component of quality health care delivery for these children.

Abstract
Trastuzumab, a humanized monoclonal antibody directed against human epidermal growth factor receptor 2 (HER2), remains the standard of care as part of adjuvant therapy for patients diagnosed with HER2-positive breast cancers. Despite high therapeutic efficacy, trastuzumab-based regimens can cause serious cardiotoxic side effects. Effective mitigation of cardiotoxic risk relies on thorough understanding of molecular mechanisms of cardiotoxicity induced by trastuzumab. Among the probable mechanisms responsible for trastuzumab-mediated cardiotoxicity, generation of free radicals causing oxidative stress has garnered notable attention in recent years. More recently, role of autophagy in trastuzumab-induced cardiomyopathy was explored. Trastuzumab-mediated HER2 signaling dysregulation activated Erk/mTOR signaling cascade resulting in autophagy inhibition. Consequently, autophagy impairment leads to massive accumulation of damaged mitochondria and free radicals causing oxidative stress and toxicity in cardiomyocytes. This review will discuss recent advances in understanding the mechanism of oxidative stress and highlight the role of autophagy in trastuzumab-mediated cardiac dysfunctions.

Abstract
Alimentary tract duplication is a rare congenital anomaly which may involve any part of the alimentary tract extending from stomach to rectum. Clinical presentation may mimic an inflamed appendix as described in this case. A 9-year-old boy with a clinical diagnosis of perforated appendix was noted to have a normal appendix intra-operatively. On further search for an underlying pathology, a gangrenous ileal duplication was discovered. En-bloc resection with primary bowel anastomosis was done. Histopathology report revealed a gangrenous small bowel duplication. We discuss the preoperative diagnostic dilemma and management options in approaching this rare entity.

Abstract
MSUD occurs due to deficiency of enzyme BCKAD required for metabolism of leucine, isoleucine, and valine leading to the accumulation of these and their ketoacids causing acute metabolic decompensation manifesting as encephalopathy or sudden death. The patient requires special protein-restricted diet to survive. As this enzyme is expressed in liver, liver transplantation has been successfully performed as a cure. We report two patients of MSUD who underwent LDLT while their livers were used as a domino graft for other biliary cirrhotic patients. A 22-month-old male child diagnosed as a case of classic MSUD underwent LDLT from an altruistic aunt as donor following which his serum leucine levels normalized on an unrestricted protein diet. His liver was used as a domino graft. A 38-month-old female child with diagnosed MSUD underwent LDLT from a swap donor, and her liver was used as a domino graft. Her DQ improved post-transplant. LDLT from non-heterozygous donors is a cure for classical MSUD. Their livers can be used as domino grafts for non-MSUD cases.

Abstract
Plummer-Vinson syndrome (PVS) is a triad of microcytic hypochromic anemia, atrophic glossitis, and esophageal webs or strictures. It is one of the syndromes associated with iron deficiency anemia. Symptoms resulting from anemia predominates the clinical picture, apart from the additional features such as glossitis, angular cheilitis, and dysphagia. Dysphagia is main clinical feature of PVS. PVS carries an increased risk of development of squamous cell carcinoma of esophagus and pharynx. A classic case report of PVS with clinical features, oral manifestations, malignant potential, differential diagnosis, investigation, dental implication, and treatment is discussed here with the literature review from the dentist's point of view. The article carries a message that dental surgeons have to be familiar with the oral manifestations of anemia and be able to suspect PVS to aid in early diagnosis and prompt treatment.

Abstract
The first order perturbation expressions for various molecular constants such as isotopic shifts (⊿λi, ⊿λi/λi), inverse isotopic shifts (⊿σi, ⊿σi/σi), Coriolis coupling constants (Δξij)and mean amplitudes of vibration (Δ∑ij) obtained using different equations and approximations are given in detail.
The mathematical and physical properties of the different approximations are discussed extensively. Incidentally some isotopic rules obtained using the first order perturbation theory are presented.

Abstract
The variation of the ratio L12/L21 (where Lij refers to the element of the L matrix) as a function of the mass coupling term T=G12/|G|1/2 has been studied for molecules of the type XY4(Td), XY3(D3h) and XY2C2v) using the exact force field data. In the case of the XY4 and XY3 type molecules, the ratio L12/L21 is nearly independent of the mass coupling and in the case of the XY2 type, it shows a nearly linear dependence on T. The force constants have been evaluated using an empirically determined constraint for L12/L21. The values are generally in good agreement with the exact ones. In all cases except VCl4 the exact interaction term of the F matrix is in agreement with the sign rule of Müller et al.

Abstract
Background Polymerase chain reaction (PCR) assay can be a useful method for definitive diagnosis in paucibacillary infections such as ocular tuberculosis (TB). In this study, we have evaluated factors affecting PCR outcomes in patients with clinically suspected ocular TB. Patients with clinically suspected ocular TB were investigated by PCR of aqueous or vitreous samples. Three control groups were also tested: group 1 included culture-proven non-tuberculous endophthalmitis, group 2 culture-negative non-tuberculous endophthalmitis, and group 3 patients undergoing surgery for uncomplicated cataract. PCR targeted one or more of following targets: IS6110, MPB64, and protein b genes of Mycobacterium tuberculosis complex. Multiple regression analysis (5% level of significance) was done to evaluate the associations between positive PCR outcome and laterality of disease, tuberculin skin test (TST)/interferon-gamma release assay (IGRA), chest radiography, and type of sample (aqueous or vitreous). The main outcome measures were positive PCR by one or more gene targets, and factors influencing positive PCR outcomes. Results All 114 samples were tested for MPB64, 110 for protein b, and 88 for IS6110. MPB64 was positive in 70.2% (n = 80) of tested samples, protein b in 40.0% (n = 44), and IS6110 in only 9.1% (n = 8). DNA sequencing of amplicons from four randomly chosen PCR reactions showed homology for M. tuberculosis complex. Of the 80 PCR-positive patients, 71 completed a full course of antitubercular therapy, of which 65 patients (91.5%) had complete resolution of inflammation at final follow-up. Among controls, 12.5% (3 out of 24) in group 1 and 18.7% (6 out of 32) in group 2 also tested positive by PCR. No PCR-positive outcome was observed in control group 3 (n = 25). Multiple regression analysis revealed significant association of positive PCR outcome with bilateral presentation, but not with a positive TST/IGRA, chest radiography, or type of sample (aqueous/vitreous) used. Conclusions Careful selection of gene targets can yield high PCR positivity in clinically suspected ocular TB. Bilateral disease presentation but not any evidence of latent systemic TB influences PCR outcomes. False-positive results may be seen in ocular inflammation unrelated to ocular TB.

Abstract
PURPOSE To assess the outcomes of repeat descemetopexy in post-cataract surgery Descemet membrane detachment. DESIGN Retrospective interventional case series. METHODS This multicenter, institutional study done between January 2007 and July 2013 included 13 eyes of 13 patients who underwent repeat descemetopexy after a failed initial procedure in post-cataract surgery Descemet membrane detachment. Patients without a minimum follow-up of 1 month were excluded. They underwent repeat descemetopexy with either 100% air or isoexpansile mixture of 14% C3F8. At 1 month, final status of Descemet membrane, final best-corrected visual acuity (BCVA), and incidence of postsurgical complications were noted. RESULTS Mean age was 63.7 ± 6.6 years; male-to-female ratio, 8:5. Descemet membrane detachment involved the visual axis in all cases. Mean interval between 2 interventions was 5.1 ± 3.1 days. Same gas was used in 9 of 13 patients (air, 4; C3F8, 5). Air was used earlier and C3F8 later in 4 patients. At 1 month, 12 of 13 patients had an attached Descemet membrane and improved mean logMAR BCVA (P = .0036). One case developed postoperative pupillary block and 1 case required endothelial transplantation. CONCLUSION Repeat descemetopexy for post-cataract surgery Descemet membrane detachment gives good anatomic and visual results and is definitely a worthwhile attempt before a complex surgical procedure like keratoplasty is offered.

Abstract
Background Ocular tuberculosis (TB) can affect nearly every ocular tissue, leading to a variety of vision-threatening clinical manifestations. The goal of this study is to estimate the degree, duration, and causes of visual impairment in eyes affected by ocular TB. Results This was a retrospective study of patients diagnosed as ocular TB based on polymerase chain reaction (PCR) for Mycobacterium tuberculosis complex. We applied the World Health Organization definition of visual impairment (VI) to affected eye(s), instead of better-seeing eye. Best-corrected visual acuity (BCVA) of <6/18 and ≥6/60 in the affected eye was classified as moderate VI and <6/60 and ≥3/60 as severe VI. Data collected included presenting and final BCVA of affected eyes and the worst BCVA during the study period. Sixty-one eyes of 40 patients were analyzed. Twenty-five patients (52.1%) had bilateral disease. The mean worst BCVA and mean final BCVA (logMAR) were 1.26 ± 0.87 and 0.61 ± 0.85, respectively, and their difference was highly significant (p < 0.0001, Friedman test). The median worst and final BCVA results were 1.30 (range 0.0 to 3.0) and 0.20 (range 0.0 to 3.0), respectively. The mean duration of follow-up was 98.34 ± 81.81 weeks. Moderate and severe VIs were seen in 14 (22.9%) and 12 (19.7%) eyes, respectively, during the course of follow up. Twenty eyes (32.8%) had BCVA of <3/60. Moderate VI or worse was most commonly seen in eyes with multifocal serpiginoid choroiditis (n = 6; 100%), retinal vasculitis (n = 25; 80.6%), and panuveitis (n = 12; 80%). The mean duration of visual loss was 25.2 ± 42.37 weeks (median 6.43 weeks, range 0 to 206.42 weeks). Vitreous hemorrhage, complicated cataract, and macular scarring were the common causes of VI. Conclusion Ocular TB can result in prolonged visual impairment, more commonly in patients with posterior uveitis or panuveitis.

Abstract
ABO incompatibility is the commonest reason for rejection of donors in living donor liver transplantation (LDLT). The donor pool could be expanded by 25 % to 35 % if the ABO barrier is overcome. In the absence of pre-conditioning, transplantation across the blood groups is fraught with the almost universal risk of antibody-mediated rejection (AMR) that rapidly leads to graft loss. However, AMR can be prevented by removal of preformed antibodies and reducing their production by B cells. We describe our initial experience of three cases of ABO-incompatible (ABO-i) LDLT: a 42-year-old male, an 8-month-old male and a 28-month-old female, all of blood group O+ who received blood group B + right lobe, B + left lateral segment, and A + left lateral segment liver grafts, respectively. Pre-LDLT conditioning included administration of anti-CD20 antibody (Rituximab(®)) to the adult 4 weeks prior, and four to seven sessions of double-filtration plasmapheresis to all, to remove preformed antibodies and achieve anti-donor blood group antibody (ADA) titers of ≤ 1:16 IgG and ≤ 1:8 IgM, respectively. In addition, cases 1 and 3 received mycophenolate mofetil for 7 days prior to LDLT. After LDLT, all three patients achieved normal graft function over 8-17 days with no evidence of AMR and without the need for further plasmapheresis. Postoperative complications included portal vein thrombosis (one successfully re-explored), CMV (one), Pseudomonas and Klebsiella sepsis (one each), and abdominal collection (one treated with percutaneous drainage). All are currently well with normal graft function and low ADA titers at 8, 16, and 19 months after ABO-i LDLT.

Abstract
OBJECTIVE Alzheimer's disease and Parkinson's disease are two of several neurodegenerative disorders that affect the elderly. Although their aetiology remains uncertain, studies suggest that elevated aluminium or other metal ions in the brain directly influence the development of the histological abnormalities normally associated with these diseases; other investigations suggest that metal-ion-induced-dysfunction of mitochondria might be a critical factor. METHODS In this study, the impact of elevated aluminum (Al3+), ferric (Fe3+), calcium (Ca2+) and magnesium (Mg2+) ions on brain histology and on the protein composition of brain mitochondria were evaluated. Rabbits were injected intra-cerebrally with 1.4% solutions of either aluminium chloride (AlCl3), ferric chloride (FeCl3), calcium chloride (CaCl2) or magnesium chloride (MgCl2) and sacrificed 10 days later RESULTS Histological analysis revealed that Al3+ but not the other ions induced neurofibrillary degeneration within the midbrain and medulla. Alternatively, SDS-PAGE revealed that Fe3+, Ca2+ and Mg2+ but not Al3+ induced alterations to the distribution of brain mitochondrial proteins. Both Fe3+ and Ca2+ triggered decreased concentration of three low molecular weight proteins (-7-14 kd) but Ca2+ precipitated their total absence. Both ions led to increased concentration of a high molecular weight protein (-110 kd). In contrast, Mg2 led to the total absence of the protein of lowest molecular weight (-7 kd) and increased concentration of a -36 kd protein. CONCLUSION These results suggest that elevation of some metal ions in the brain induces protein aggregation with the nature of the aggregation being highly ion dependent. The results also point toward major differences between the histopathological effect of Al3+ and other ions.

Abstract
INTRODUCTION Phyllodes tumor (PT) is a rare tumor of the breast. Usually, difficulty in making preoperative diagnoses and unpredictable clinical outcome of this disease leads to inappropriate management. Till date, no definite conclusion regarding the appropriate surgical procedure can be drawn. OBJECTIVES The objective of this retrospective study is to study the clinicopathological correlation of phyllodes tumors in North-Central part of the India and also to evaluate efficacy of the various surgical options available for the management of phyllodes tumors of the breast. MATERIALS AND METHODS A retrospective study of 24 cases from the archives of department of surgery of three tertiary institutes of North-Central part of India. We reviewed the clinical, pathological features of this disease entity with a view to highlight relevant features. We also analyzed various surgical options done for primary as well as recurrent PT. RESULTS The breast masses in our study were particularly large. The mean size of the lump was 9.5 +/- 5.5 cm (range was 4.0-23 cm). Histopathological report was benign, borderline, and malignant PT in 62.4%, 20.8%, and 16.8% of the cases, respectively. Overall, 31 surgical procedures (24 in primary and 7 in recurrent) were performed. Simple lumpectomy, wide local excision and simple mastectomy were done in 25%, 27.4% and 27.4% of primary (non-recurrent) cases of PT, respectively. Modified radical mastectomy and simple mastectomy with LD flap reconstruction was done in 7.2% and 2.4% in primary cases, respectively in recurrent cases, simple mastectomy was done in four cases and modified radical mastectomy was done in one case. Overall, recurrence was seen in 29.2% of the cases. The median time for recurrence was 6 months (range 5.0-36 months). 90% (6/7) of recurrence occurred in lumpectomy patients. CONCLUSION The unpredictable behavior of histological types and the disputable results of particular surgical procedures have contributed to the controversies. The therapeutic issue is further compounded by an imprecise preoperative diagnosis. This study shows that wide local excision for benign and borderline and simple mastectomy with or without reconstruction for the malignant PT of the breast are acceptable best surgical options.
