  • Supracondylar Femoral Extension Osteotomy and Patellar Tendon Advancement in the Management of Persistent Crouch Gait in Cerebral Palsy
    Original Article Supracondylar femoral extension osteotomy and patellar tendon advancement in the management of persistent crouch gait in cerebral palsy Sakti Prasad Das, Sudhakar Pradhan, Shankar Ganesh1, Pabitra Kumar Sahu, Ram Narayan Mohanty, Sanjay Kumar Das ABSTRACT Background: Severe crouch gait in adolescent cerebral palsy is a difficult problem to manage. The patients develop loading of patellofemoral joint, leading to pain, gait deviation, excessive energy expenditure and progressive loss of function. Patella alta and avulsion of patella are the other complications. Different treatment options have been described in the literature to deal with this difficult problem. We evaluated outcome of supracondylar femoral extension osteotomy (SCFEO) and patellar tendon advancement (PTA) in the treatment of crouch gait in patients with cerebral palsy. Materials and Methods: Fourteen adolescents with crouch gait were operated by SCFEO and PTA. All subjects were evaluated pre and postoperatively. Clinical, radiographic, observational gait analysis and functional measures were included to assess the changes in knee function. Results: Cases were followed up to 3 years. The patients walked with increased knee extension and improvement in quadriceps muscle strength. Knee pain was decreased and improvements in functional mobility and radiologic improvement were found. Conclusion: SCFEO and PTA for adolescent crouch gait is effective in improving knee extensor strength, reducing knee pain and improving function. Key words: Crouch gait, patellar

Post-irradiation or secondary angiosarcoma of the breast was rst described in the 1980s in patients treated with breast conserving therapy for cancer. The primary management of radiation-induced breast angiosarcoma has focused on surgical resection with an emphasis on achieving negative tumor margins. While surgery remains a key component of treatment, novel therapeutic approaches have surfaced. Despite such advances in treatment, prognosis remains poor.

Sphingolipidoses are a group of inherited genetic diseases characterized by the unmetabolized sphingolipids and the consequent reduction of ceramide pool in lysosomes. Sphingolipidoses include several disorders as Sandhoff disease, Fabry disease, Gaucher disease, metachromatic leukodystrophy, Krabbe disease, Niemann Pick disease, Farber disease, and GM2 gangliosidosis. In sphingolipidosis, lysosomal lipid storage occurs in both the central nervous system and visceral tissues, and central nervous system pathology is a common hallmark for all of them. Parkinson’s disease, the most common neurodegenerative movement disorder, is characterized by the accumulation and aggregation of misfolded α-synuclein that seem associated to some lysosomal disorders, in particular Gaucher disease. This review provides evidence into the role of ceramide metabolism in the pathophysiology of lysosomes, highlighting the more recent findings on its involvement in Parkinson’s disease.

Conversely in man, deficient 12 mitophagy due to Pink1/Parkin mutations triggers iron accumulation in patient brain and limits 13 survival. We now aimed to identify murine fibroblast factors, which adapt their mRNA expression 14 to acute iron manipulation, relate to mitochondrial dysfunction and may influence survival. After 15 iron depletion, expression of the plasma membrane receptor Tfrc with its activator Ireb2, the 16 mitochondrial membrane transporter Abcb10, the heme-release factor Pgrmc1, the heme- 17 degradation enzyme Hmox1, the heme-binding cholesterol metabolizer Cyp46a1, as well as the 18 mitophagy regulators Pink1 and Parkin showed a negative correlation to iron levels. After iron 19 overload, these factors did not change expression. Conversely, a positive correlation of mRNA levels 20 with both conditions of iron availability was observed for the endosomal factors Slc11a2 and Steap2, 21 as well as for the iron-sulfur-cluster (ISC)-containing factors Ppat, Bdh2 and Nthl1.

  • Primary Liver Cancer: Epidemiological And
    PRIMARY LIVER CANCER: EPIDEMIOLOGICAL AND BIOMARKER DISCOVERY STUDIES Nimzing Gwamzhi Ladep Imperial College London Department of Medicine December 2013 Thesis submitted for Doctor of Philosophy 1 THESIS ABSTRACT With previous reports indicating changes in mortality, risk factors and management of primary liver cancer (PLC), evaluation of current trends in the incidence and mortality rates was indicated. Late diagnosis has been implicated to be a major contributor to the high fatality rates of PLC. This work aimed at: studying trends of PLC by subcategories globally in general, and in England and Wales, in particular; investigating liver-related morbidities of HIV infected patients in an African setting; and discovering urinary biomarkers of hepatocellular carcinoma. The World Health Organisation (WHO) and Small Area Health Statistics Unit (SAHSU) databases were interrogated respectively, in order to achieve the first aim. The second aim was achieved through utilisation of databases of an African-based HIV treatment programme- AIDS Prevention Initiative in Nigeria (APIN), located in Jos, Nigeria. The European Union-funded Prevention of Liver Fibrosis and Cancer in Africa (PROLIFICA) case-control study in three West African countries was the platform through which urinary metabolic profiling was accomplished. Proton nuclear magnetic resonance spectroscopy (NMR) and parallel ultra-performance liquid chromatography mass spectrometry (UPLC-MS) were used for biomarker discovery studies. Mortality rates of intrahepatic bile duct carcinoma (IHBD) increased in all countries that were studied. Misclassification of hilar cholangiocarcinoma accounted for only a small increase in the rate of IHBD in England and Wales. With over 90% screening rate for viral hepatitides, the rates of hepatitis B (HBV), hepatitis C (HCV) and 2 HBV/HCV in HIV-infected patients in the APIN programme were 17.8%, 11.3% and 2.5% respectively.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

  • Understanding the Molecular Pathobiology of Acid Ceramidase Deficiency
    Understanding the Molecular Pathobiology of Acid Ceramidase Deficiency By Fabian Yu A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Institute of Medical Science University of Toronto © Copyright by Fabian PS Yu 2018 Understanding the Molecular Pathobiology of Acid Ceramidase Deficiency Fabian Yu Doctor of Philosophy Institute of Medical Science University of Toronto 2018 Abstract Farber disease (FD) is a devastating Lysosomal Storage Disorder (LSD) caused by mutations in ASAH1, resulting in acid ceramidase (ACDase) deficiency. ACDase deficiency manifests along a broad spectrum but in its classical form patients die during early childhood. Due to the scarcity of cases FD has largely been understudied. To circumvent this, our lab previously generated a mouse model that recapitulates FD. In some case reports, patients have shown signs of visceral involvement, retinopathy and respiratory distress that may lead to death. Beyond superficial descriptions in case reports, there have been no in-depth studies performed to address these conditions. To improve the understanding of FD and gain insights for evaluating future therapies, we performed comprehensive studies on the ACDase deficient mouse. In the visual system, we reported presence of progressive uveitis. Further tests revealed cellular infiltration, lipid buildup and extensive retinal pathology. Mice developed retinal dysplasia, impaired retinal response and decreased visual acuity. Within the pulmonary system, lung function tests revealed a decrease in lung compliance. Mice developed chronic lung injury that was contributed by cellular recruitment, and vascular leakage. Additionally, we report impairment to lipid homeostasis in the lungs. ii To understand the liver involvement in FD, we characterized the pathology and performed transcriptome analysis to identify gene and pathway changes.

    Cancer information fact sheet Understanding Appendix Cancer and Pseudomyxoma Peritonei (PMP) A guide for people affected by cancer This fact sheet has been prepared What is appendix cancer? to help you understand more about Appendix cancer occurs when cells in the appendix appendix cancer and pseudomyxoma become abnormal and keep growing and form a peritonei (PMP). mass or lump called a tumour. Many people look for support after The type of cancer is defined by the particular being diagnosed with a cancer that cells that are affected and can be benign (non- is rare or less common than other cancerous) or malignant (cancerous). Malignant cancer types. This fact sheet includes tumours have the potential to spread to other information about how these cancers parts of the body through the blood stream or are diagnosed and treated, as well as lymph vessels and form another tumour at a where to go for additional information new site. This new tumour is known as secondary and support services. cancer or metastasis. Many people feel shocked and upset when told they have cancer. You may experience strong emotions The abdomen after a cancer diagnosis, especially if your cancer is rare or less common like appendix cancer or PMP. A feeling of being alone is usual with rare cancers, and you might be worried about how much is known about your type of cancer as well as how it will be managed. You may also be concerned about the cancer coming back after treatment. Linking into local support services (see last page) can help overcome feelings of isolation and will give you information that you may find useful.

  • Investigation of Candidate Genes and Mechanisms Underlying Obesity
    Prashanth et al. BMC Endocrine Disorders (2021) 21:80 https://doi.org/10.1186/s12902-021-00718-5 RESEARCH ARTICLE Open Access Investigation of candidate genes and mechanisms underlying obesity associated type 2 diabetes mellitus using bioinformatics analysis and screening of small drug molecules G. Prashanth1 , Basavaraj Vastrad2 , Anandkumar Tengli3 , Chanabasayya Vastrad4* and Iranna Kotturshetti5 Abstract Background: Obesity associated type 2 diabetes mellitus is a metabolic disorder ; however, the etiology of obesity associated type 2 diabetes mellitus remains largely unknown. There is an urgent need to further broaden the understanding of the molecular mechanism associated in obesity associated type 2 diabetes mellitus. Methods: To screen the differentially expressed genes (DEGs) that might play essential roles in obesity associated type 2 diabetes mellitus, the publicly available expression profiling by high throughput sequencing data (GSE143319) was downloaded and screened for DEGs. Then, Gene Ontology (GO) and REACTOME pathway enrichment analysis were performed. The protein - protein interaction network, miRNA - target genes regulatory network and TF-target gene regulatory network were constructed and analyzed for identification of hub and target genes. The hub genes were validated by receiver operating characteristic (ROC) curve analysis and RT- PCR analysis. Finally, a molecular docking study was performed on over expressed proteins to predict the target small drug molecules. Results: A total of 820 DEGs were identified between
