Neonatal pertussis diagnosis: low procalcitonin level and high lymphocyte count are able to discriminate pertussis from bacterial and viral infections.

New Microbiol 2019 Feb 20;42(1). Epub 2019 Feb 20.

Dipartimento di Pediatria Sistematica, Pediatria 1, AORN "Santobono-Pausilipon", Napoli, Italy.

Pertussis is quite frequent and severe among infants; therefore, rapid diagnosis and timely targeted therapy are essential. Although a molecular test for etiological diagnosis is now available, it may not be available everywhere, and therefore adjunctive diagnostic tests are still useful for presumptive diagnosis. We describe the use of procalcitonin (PCT) and lymphocyte count to discriminate among pertussis, bacterial and viral infections. Read More

Non-Celiac Gluten Sensitivity: A Challenging Diagnosis in Children with Abdominal Pain.

Authors:
Frank M Ruemmele

Ann Nutr Metab 2018 19;73 Suppl 4:39-46. Epub 2019 Feb 19.

Université Paris Descartes, Sorbonne Paris Cité, Paris,

Several disorders related to the ingestion of gluten are well recognized despite overlapping clinical presentations: celiac disease, an autoimmune enteropathy triggered by gluten ingestions in susceptible individuals, allergy to wheat, and more recently non-celiac gluten sensitivity (NCGS). While celiac disease and wheat allergy are well-known disorders with a clear-cut diagnosis based on clinical tests and biological parameters, NCGS is a more difficult diagnosis, especially in children with functional gastrointestinal (GI) complaints. NCGS is considered a syndrome of intestinal but also extraintestinal symptoms occurring within hours, but sometimes even after several days of gluten ingestion. Read More

Recovery of Four Novel Potato spindle tuber viroid Sequence Variants from Russian Seed Potatoes.

Plant Dis 2007 Apr;91(4):469

Molecular Plant Pathology Laboratory, Henry A. Wallace Agricultural Research Center, ARS, USDA, Beltsville, MD 20705.

First described in the early 1930s, the limited distribution of potato "gothic" disease made it of little economic significance in European Russia until the early 1970s when meristem-tip culture was widely adopted throughout the former USSR to increase production of virus-free seed potatoes. Shortly thereafter, the yield and quality of Russian seed potatoes began a dramatic decline. Symptoms of potato "gothic" resemble those of Potato spindle tuber viroid (PSTVd) (3), and initial suspicions that in vitro plantlets and seed potatoes might be viroid-infected were later proved correct when Kastalyeva et al.

Methods: A total of 91 patients scheduled for shoulder arthroscopy from March 2015 to April 2017 were included in the present study. To assess the sensitivity, specificity, positive and negative predictive values, accuracy, diagnostic odds ratio, positive and negative likelihood ratios, and the area under the curve (AUC), intraoperative findings were compared with the results of 6 established clinical infraspinatus tests: the hornblower's test, the drop sign, the Patte sign, the external rotation lag sign (ERLS), the resisted external rotation test (RERT), and the infraspinatus scapular retraction test.

Prognostic Implications of Minimal/Covert Hepatic Encephalopathy: Large-scale Validation Cohort Studies.

J Clin Exp Hepatol 2019 Jan-Feb;9(1):112-116. Epub 2018 May 4.

Division of Gastroenterology and Hepatology, University of Arkansas for Medical Sciences, Little Rock, AR, USA.

Minimal or Covert Hepatic Encephalopathy (MHE/CHE), the preclinical phase of Hepatic Encephalopathy (HE), is strongly associated with poorer Quality of Life (QOL), Overt HE (OHE), and death. Several diagnostic tests have been developed that have prognostic value in predicting clinical outcomes such as OHE, cirrhosis progression, and death. However, dispute among clinicians and HE researchers have kept its application largely underutilized. Read More

Values of diagnostic tests for the various species of spirochetes.

Med Mal Infect 2019 Feb 11. Epub 2019 Feb 11.

IRD, AP-HM, MEPHI, IHU-Méditerranée Infection, Aix Marseille Université, 13005 Marseille, France.

Bacteria of the Borrelia burgdorferi sensu lato complex, responsible for Lyme disease, are members of the spirochetes phylum. Diagnostic difficulties of Lyme disease are partly due to the characteristics of spirochetes as their culture is tedious or even impossible for some of them. We performed a literature review to assess the value of the various diagnostic tests of spirochetes infections of medical interest such as Lyme borreliosis, relapsing fever borreliae, syphilis, and leptospirosis.

Diagnosing Immune Thrombocytopenia.

Authors:
Ulrich J Sachs

Hamostaseologie 2019 Feb 14. Epub 2019 Feb 14.

Institute for Clinical Immunology and Transfusion Medicine, Justus Liebig University, Giessen, Germany.

Although the detection of a characteristic autoantibody can prove immune thrombocytopenia (ITP), this diagnosis is often based on the exclusion of other causes of thrombocytopenia. Direct glycoprotein (GP)-specific tests have the property required to demonstrate such a characteristic autoantibody. In contrast, platelet-associated immunoglobulin G or antibody detection in plasma or serum is an insufficient diagnostic test. Read More

Risk of diagnostic delay in congenital thrombotic thrombocytopenic purpura.

J Thromb Haemost 2019 Feb 14. Epub 2019 Feb 14.

Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Angelo Bianchi Bonomi Hemophilia and Thrombosis Center and Fondazione Luigi Villa, Milan, Italy.

Thrombotic thrombocytopenic purpura (TTP) is an acute life-threatening disorder characterized by multiple organ ischemia due to disseminated thrombi formation in the microvasculature. The congenital form of the disease (Upshaw-Schulman syndrome) is related to ADAMTS13 mutations. Adulthood-onset of TTP does not exclude the congenital form of the disease and a diagnostic delay may account for a great morbidity burden in these patients. Read More

Self-reported face recognition is highly valid, but alone is not highly discriminative of prosopagnosia-level performance on objective assessments.

Behav Res Methods 2019 Feb 13. Epub 2019 Feb 13.

Department of Psychiatry, Harvard Medical School, Boston, MA, USA.

Severe developmental deficits in face recognition ability (developmental prosopagnosia, or DP) have been vigorously studied over the past decade, yet many questions remain unanswered about their origins, nature, and social consequences. A rate-limiting factor in answering such questions is the challenge of recruiting rare DP participants. Although self-reported experiences have long played a role in efforts to identify DPs, much remains unknown about how such self-reports can or should contribute to screening or diagnosis. Read More
