Opportunistic Fonsecaea pedrosoi brain abscess in a patient with non-cirrhotic portal fibrosis-induced hypersplenism--a novel association.

Non-cirrhotic portal fibrosis, a common cause of splenomegaly in tropical countries, can lead to hypersplenism and pancytopenia. Hypersplenism in this setting has not been associated with opportunistic infections. We describe a patient with hypersplenism secondary to non-cirrhotic portal fibrosis who developed a Fonsecaea pedrosoi brain abscess and succumbed to the illness despite aggressive management.

Enhancing early detection of neurological and developmental disorders and provision of intervention in low-resource settings in Uttar Pradesh, India: study protocol of the G.A.N.E.S.H. programme.

INTRODUCTION: Around 9% of India's children under six are diagnosed with neurodevelopmental disorders. Low-resource, rural communities often lack programmes for early identification and intervention. The Prechtl General Movement Assessment (GMA) is regarded as the best clinical tool to predict cerebral palsy in infants <5 months. In addition, children with developmental delay, intellectual disabilities, late detected genetic disorders or autism spectrum disorder show abnormal general movements (GMs) during infancy. General Movement Assessment in Neonates for Early Identification and Intervention, Social Support and Health Awareness (G.A.N.E.S.H.) aims to (1) provide evidence as to whether community health workers can support the identification of infants at high-risk for neurological and developmental disorders and disabilities, (2) monitor further development in those infants and (3) initiate early and targeted intervention procedures. METHODS: This 3-year observational cohort study will comprise at least 2000 infants born across four districts of Uttar Pradesh, India. Community health workers, certified for GMA, video record and assess the infants' GMs twice, that is, within 2 months after birth and at 3-5 months. In case of abnormal GMs and/or reduced MOSs, infants are further examined by a paediatrician and a neurologist. If necessary, early intervention strategies (treatment as usual) are introduced. After paediatric and neurodevelopmental assessments at 12-24 months, outcomes are categorised as normal or neurological/developmental disorders. Research objective (1): to relate the GMA to the outcome at 12-24 months. Research objective (2): to investigate the impact of predefined exposures. Research objective (3): to evaluate the interscorer agreement of GMA. ETHICS AND DISSEMINATION: G.A.N.E.S.H. received ethics approval from the Indian Government Chief Medical Officers of Varanasi and Mirzapur and from the Ramakrishna Mission Home of Service in Varanasi. GMA is a worldwide used diagnostic tool, approved by the Ethics Committee of the Medical University of Graz, Austria (27-388 ex 14/15). Apart from peer-reviewed publications, we are planning to deploy G.A.N.E.S.H. in other vulnerable settings.

Role of C-Reactive Protein, White Blood Cell Counts, Bilirubin Levels, and Imaging in the Diagnosis of Acute Appendicitis as a Cause of Right Iliac Fossa Pain.

Background Right iliac fossa (RIF) pain is one of the most common modalities of presentation to surgical emergency. It remains a challenge to the treating clinicians to accurately diagnose or to rule out appendicitis. Objective The aim of the study was to compare the efficacy of clinical impression, biochemical markers, and imaging in the diagnosis of RIF pain with special reference to appendicitis and their implication in reducing the negative appendicectomy rates. Methods All patients presenting to casualty with RIF pain were included in the study. Blood investigations including C-reactive protein (CRP), serum bilirubin, white blood cell counts (WBC), and ultrasound (USG) were done. Based on the clinical impression, patients were either posted for appendicectomy or observed in equivocal cases. Patients who had recurrent pain on follow-up underwent appendicectomy or underwent contrast-enhanced computed tomography (CECT) in equivocal cases. Patients who only had a single self-limiting episode with no other alternative diagnosis or had a normal CECT report were included in a non-specific RIF pain group. Results The negative appendicectomy rate was 8.2%. The mean value of WBC counts (9.57x109/L vs 7.88x109/L; p<0.05) and that of serum bilirubin (1.37 mg/dl vs 0.89mg/dl; p<0.05) in the appendicitis and non-appendicitis group, respectively, were statistically significant. The percentage of CRP positivity was higher in the appendicitis group (51.9% vs 15%; p<0.05). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for USG (84.2%, 77.17%, 85.4%, and 75.5%), for CRP (51.8%, 85%, 82%, and 57%), for WBC count (45.1%, 88%, 86.6%, and 48.3%), and for serum bilirubin (69.2%, 75%, 81.4%, and 60.5%) were statistically significant between the groups. Conclusion Imaging and biochemical investigations including bilirubin can act as useful adjuncts to the clinical diagnosis of appendicitis.

Bifunctional Polysulfone-Chitosan Composite Hollow Fiber Membrane for Bioartificial Liver.

Hollow fiber membranes are widely used as assist devices for bioartificial liver application. Asymmetric porous polysulfone and polysulfone-tocopheryl polyethylene glycol succinate (Psf-TPGS) composite hollow fiber and flat membranes were prepared by phase inversion procedure and subsequently surface modified with chitosan using sulfonation with concentrated sulfuric acid. Sulfonation induces negative charge on the prepared membrane surface and facilitates the attachment of chitosan amine groups by electrostatic interaction. The surface modification of membrane is stable at room temperature as dictated by presence of nitrogen in XPS analysis and amide linkages in FT-IR spectra. Further, biological studies of the membranes were performed using HepG2 cell line. Chitosan is biocompatible and shows structural similarity to glycosaminoglycans, a native liver ECM component. The chitosan-modified composite Psf and Psf-TPGS membranes have shown enhanced attachment and proliferation of HepG2 cells on outer surface as confirmed by the cell counting, DNA content, confocal microscopy, and SEM micrographs. The cells form a 3D multicellular spheroid structure on the chitosan-modified membranes in significantly larger number as seen in the SEM micrographs. Also, the hemocompatibility of the modified composite membranes were comparable to the unmodified membranes. Thus, the chitosan-modified composite membranes we have developed are bifunctional and have the potential to be used in bioartifical liver application.

Anaplastic large cell lymphoma in a patient with systemic onset juvenile arthritis: case report and review of literature.

The association of malignancy with autoimmune rheumatic diseases has been a subject of investigation. It has been shown that there is increased risk of malignancies, mainly non-Hodgkin lymphoma, in patients with autoimmune disorders. There is scarcity of data about malignancy in juvenile idiopathic arthritis (JIA). We report the occurrence of anaplastic large cell lymphoma in a patient with systemic onset juvenile idiopathic arthritis treated with low dose methotrexate (MTX). A relationship between MTX treatment and the occurrence of lymphoma in autoimmune diseases has been suggested. The hypothesis that MTX has a role in the aetiology of lymphoproliferative disorders is supported by the observation of spontaneous remission of lymphoma in few cases on cessation of MTX therapy. However, systemic onset juvenile idiopathic arthritis patients receiving MTX must be periodically examined for the development of lymphoproliferative disorder especially if the disease is difficult to control or patient develop new symptoms on therapy.
