    Genetic Analysis of Syndromic and Nonsyndromic Patients With Craniosynostosis Identifies Novel Mutations in the TWIST1 and EFNB1 Genes.
    Cleft Palate Craniofac J 2018 Jan 1:1055665618760412. Epub 2018 Jan 1.
    1 Department of Genetics and Biotechnology, School of Physical Sciences, Faculty of Biology, National and Kapodistrian University of Athens, Athens, Greece.
    Introduction: Craniosynostosis, the premature fusion of cranial sutures, is usually divided into 2 major categories: syndromic and nonsyndromic. Mutations in the FGFR1, FGFR2, FGFR3, TWIST1, and EFNB1 genes cause the common craniosynostosis syndromes Muenke, Crouzon and Crouzon with acanthosis nigricans, Apert, Pfeiffer, Saethre-Chotzen, and Craniofrontonasal. Overlapping features among craniosynostosis syndromes, phenotypic heterogeneity even within the same syndrome, especially in the case of Muenke syndrome, and inadequate clinical evaluation can lead to misdiagnosis, which molecular testing can help clarify.

    Phenotypic and metabolic dichotomy in obesity: clinical, biochemical and immunological correlates of metabolically divergent obese phenotypes in healthy South Asian adults.
    Singapore Med J 2018 Feb 12. Epub 2018 Feb 12.

    1 Division of Plastic Surgery, the Children's Hospital of Philadelphia, Philadelphia, PA, USA.
    Crouzon syndrome with acanthosis nigricans (CAN) is caused by a mutation in the fibroblast growth factor receptor ( FGFR) 3 gene that presents clinically as Crouzonoid craniofacial features in association with other anomalies such as acanthosis nigricans and benign odontogenic tumors. Diagnosis through the use of genetic mutational analysis is critical, as it alerts the surgeon to the need for careful screening for jaw tumors so that timely treatment in the form of curettage or segmental resection can be provided.

    Terra firma-forme dermatosis (TFFD) is a clinical condition characterized by brown-gray, velvety, pigmented patches or plaques, resembling dirt on the skin. Nevoid acanthosis nigricans (NAN) is a rare and recently described form of acanthosis nigricans occurring during childhood or early adulthood. Herein we describe a patient with TFFD, initially misdiagnosed as NAN. Read More

    Prevalence of Acanthosis nigricans and Related Factors in Iranian Obese Children.
    J Clin Diagn Res 2017 Jul 1;11(7):SC05-SC07. Epub 2017 Jul 1.
    Assistant Professor, Pediatric Intensifier, Children's Medical Center, Pediatrics Center of Excellence, Tehran University of Medical Sciences, Tehran, Iran.
    Introduction: Recognition of Acanthosis nigricans (AN) provides important opportunities for screening of obesity syndrome, dyslipidemia, hypertension and insulin resistance with diabetes mellitus 2. Considering the high prevalence of obesity among Iranian children, we designed this study to estimate the prevalence of AN and related laboratory factors in Iranian obese children.

    Materials And Methods: Seventy-one obese children were enrolled in this study. Read More

    Background: Type 2 diabetes mellitus is characterized by relative insulin deficiency and insulin resistance. Features suggesting severe insulin resistance include acanthosis nigricans, hyperandrogenism, weight loss, and recurrent hospital admissions for diabetic ketoacidosis. In rare circumstances, hyperglycemia persists despite administration of massive doses of insulin. Read More

    Type 1 Diabetes and Non-Alcoholic Fatty Liver Disease: When Should We Be Concerned? A Nationwide Study in Brazil.
    Nutrients 2017 08 15;9(8). Epub 2017 Aug 15.
    Department of Internal Medicine, Diabetes Unit, State University of Rio de Janeiro (UERJ), Boulevard 28 de Setembro, 77-3º andar-Vila Isabel, Rio de Janeiro-RJ CEP 20551-030, Brazil.
    Obesity is increasing worldwide, affecting even patients with type 1 diabetes (T1D). A higher prevalence of associated comorbidities is expected, such as non-alcoholic fatty liver disease (NAFLD). This paper reports a cross-sectional multicenter study on a population with T1D ( = 1662), which aimed to evaluate the prevalence of metabolic syndrome (MS), a known risk factor for NAFLD, and to investigate predisposing factors associated with MS, as well as factors associated with elevated alanine aminotransferase (ALT), as it correlates to liver fat content.

    Department of Paediatric Endocrinology, Alder Hey Children's National Health Service Foundation Trust, Liverpool, UK.
    Acanthosis nigricans (AN) is the most common cutaneous manifestation of insulin resistance (IR) and is commonly seen in non-Caucasian populations. Variable benefits of metformin in the treatment of AN have been reported in the literature. We report an adolescent Caucasian boy with IR and extensive AN who showed complete resolution of AN after 2 years of metformin, despite persistence of IR. Read More
