Tick-Borne Illness for Emergency Medicine Providers

AbstractPurpose of ReviewTicks are the most important vectors of human diseases after mosquitoes. Emergency physicians throughout the USA can be expected to encounter Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, and other disorders based upon geographic location.Recent FindingsThe number of identifiable disorders transmitted by these arthropods has increased in recent years. Severe fever with thrombocytopenia syndrome has only been described within the past decade, and the new millennium has seen over 10 new species of rickettsial disease discovered.SummaryTicks transmit more pathogenic species than any other group of blood-feeding arthropods. This review provides an update on the diagnosis and management of the diseases most likely to be encountered in clinical practice.

Conclusion: Increased incidence of dengue fever with encephalopathy in the recent years, in the absence of single sensitive test for detecting dengue encephalopathy, variable CSF and MRI Brain features, and associated high morbidity and mortality poses a big problem for clinician. This study may be helpful in focussing on early diagnosis and aggressive initial management which can influence final outcome. PMID: 31299837 [PubMed - in process]

Authors: Sharma R, Mahajan SK, Singh B, Raina R, Kanga A Abstract Aims: To study predictors of severity in patients of scrub typhus admitted in a tertiary care hospital. Material and Methods: Total 92 patients of scrub typhus were included in the study. The diagnosis was established by presence of IgM antibodies by Indirect Immunofluorescence Assay (IFA) test which is currently the reference standard for the diagnosis of scrub typhus. The clinical and laboratory profile, course in hospital, and outcome were documented. Factors associated with severe disease were analyzed. Observations: Fever (100%), cough (...

Abstract Despite close association between camels and humans, molecular based studies on vector-borne pathogens infecting camels are scarce compared to other animals in Iran. The current study was carried out to investigate the occurrence of vector-borne bacteria in the blood of dromedaries by molecular tools. A total of 200 peripheral blood samples were collected from apparently healthy animals. Microscopic examination was performed on Giemsa-stained blood smears, and drops of blood were spotted on Whatman FTA® cards for molecular analyses. Genomic DNA was extracted from the cards, and PCR amplification follo...

Serpa, Stanley Lima, Ralph Maturano, João L.H. Faccini, Douglas McIntoshAbstractRickettsia parkeri sensu stricto (s.s.) is an emerging human pathogen in the Americas. Comprehension of the etiology of R. parkeri infections in South America is complicated by the existence of genetic variants (Atlantic rainforest, NOD and Parvitarsum) of this species that are associated with specific groups of Amblyomma ticks. The rickettsial bacterium strain ApPR was firs...

In this study, a PCR/RFLP method, earlier developed for specific detection of A. platys-like strains in animal species other than camels, was adapted in order to subtype A. platys-like strains isolated from camels and their ticks and to differentiate them from pathogenic A. platys without going through a sequencing step. This approach was used for investigating the infections with A. platys and related strains in 412 Camelus dromedarius camels and 334 feeding ticks from five Tunisian governorates. Microscopic examination using Giemsa-stained blood smears was performed in order to specify which types of cells were infected....

ConclusionGaucheroma is a rare condition in regularly treated GD patients. This patient showed poor response to doubled ERT doses. The imaging studies are necessary for Gaucher patients to detect Gaucheroma and determine their malignancy. Regular checkups are recommended in all GD patients even with ERT treatment, due to the possibility of having a deteriorating change, like Gaucheroma.

Authors: Eslick R, McLintock C Abstract Around 1 in 10 pregnant women will develop thrombocytopenia during an otherwise unremarkable pregnancy. While the most frequent cause is gestational thrombocytopenia, a benign clinical entity which typically induces a mild platelet fall in late pregnancy, a number of important pregnancy-specific causes must be excluded, particularly pre-eclampsia and its severe form hemolysis with elevated liver enzymes and low platelets (HELLP). For women who do not have an identifiable pregnancy-related cause of thrombocytopenia, an underlying medical condition should be considered. The mos...

The “Christmas tree” orientation of scaling lesions along the skin tension (Langer) lines in pityriasis rosea is well known. This pattern is best appreciated on complete examination of the trunk, in which the eruption follows the long axis of the V-shaped lines of the upper chest and back, emanating around the axillae, and running transversely along the abdominal wall and lower back. Secondary syphilis has a similar presentation. When patients present with asymptomatic, larger, nonscaling patches along Langer lines, another condition deserves diagnostic consideration.
