The dentist’s role in syphilis prevention and control

Abstract Histoid leprosy is an uncommon form of lepromatous leprosy with distinct clinical, histopathological, immunological, and bacteriological features. This variant usually occurs in multibacillary patients who have irregular or inadequate treatment. Herein, we report a case of de novo histoid leprosy diagnosed in a patient from Cali, Colombia. In endemic areas, histoid leprosy should be in the differential diagnosis of any patient presenting with skin nodules. Early diagnosis and appropriate treatment are recommended for mitigating the impact of histoid leprosy cases, which are important reservoirs of Mycobacterium leprae.

Gedye, WE PomroyAbstractThe aims of this study were to monitor the change in Theileria orientalis Ikeda type infection intensity, haematocrit, milk production and reproduction on three New Zealand spring calving dairy herds, over the 2014 to 2015 milking season.Three spring calving dairy farms, A, B and C, from high risk (endemically stable), low risk (endemically unstable), and zero risk (disease-free) tick areas respectively were followed through the 2014 to 2015 milking season. On Farms, A and B, 100 cows were ra...

AndersonAbstractBuilding on past research, we here develop an analytic framework for describing the dynamics of the transmission of soil-transmitted helminth (STH) parasitic infections near the transmission breakpoint and equilibria of endemic infection and disease extinction, while allowing for perturbations in the infectious reservoir of the parasite within a defined location. This perturbation provides a model for the effect of infected human movement between ...

We present vaginal cystic lesion which posed diagnostic dilemma and was confirmed on cytology to being filarial in etiology. The patient was treated with single-dose of oral diethylcarbamazine and the lesion subsided on follow up scans at three months thus avoiding inadvertent surgeries.Vaginal cystic lesions are rare entities and have multiple etiologies. A high degree of suspicion for filariasis as cause of vaginal cystic lesions should be made in individuals hailing from or have history of travel to endemic regions of filariasis.

Dengue is a vector-borne disease with a significant impact on Latin America. According to the annual report of the Pan American Health Organization, Colombia is the main contributor of dengue in the Andean region, and the second in Latin America, with an incidence of 321.4 cases per 100,000 inhabitants in 2016 (WHO, 2017). Colombia is hyperendemic (Guzm án and Kouri, 2003; Pérez et al., 2016), and approximately 65% of Colombian municipalities have ecological conditions that favor the sustained circulation of Aedes aegypti and the transmission of dengue virus (DENV) (Díaz-Quijano et al., 2018).

ConclusionsTo our knowledge, this study documents the first example of a successful PPP with government partnership in a high-income country to address undocumented migrants ’ lack of access to health services in general and HIV care in particular. In light of the intensification of North-South migration, this Israeli case study could be useful for other countries facing similar challenges. It also has lessons within Israel, as the country grapples with other health p roblems among uninsured communities.

Although habitat loss has large, consistently negative effects on biodiversity, its genetic consequences are not yet fully understood. This is because measuring the genetic consequences of habitat loss requires accounting for major methodological limitations like the confounding effect of habitat fragmentation, historical processes underpinning genetic differentiation, time-lags between the onset of disturbances and genetic outcomes, and the need for large numbers of samples, genetic markers, and replicated landscapes to ensure sufficient statistical power. In this paper we overcame all these challenges to assess the genet...

In conclusion, while travelling to endemic countries, people should be informed about the importance of malaria prophylaxis and prophylaxis should be commenced immediately and continued appropriately. Additionally, malaria should always be considered in the differential diagnosis of high fever for the patients who admitted to the hospital with a travelling history to these countries.

Authors: Çulha G, Kaya T, Gülbol Duran G, Urhan Küçük M, Doğramacı AÇ, Tiyekli Çelik D Abstract Leishmaniasis is a parasitic disease that is transmitted to humans by the bites of infected female phlebotomine sandflies. In the diagnosis of cutaneous leishmaniasis (CL), in the smear samples, the demonstration of the parasite by microscope remains a gold standard method. However, it becomes difficult to diagnose the parasite since the number of amastigotes in chronic cases with a lesion of one year or longer is very low. Due to many factor such as patients primarily do not ...

In conclusion, T-SPOT.TB was found more reliable in the diagnosis of LTBI in HIV-infected individuals. In the light of these findings, especially in HIV-infected patients with low CD4+ T lymphocyte counts, T-SPOT.TB test can be considered for LTBI diagnosis. PMID: 31709936 [PubMed - in process]

In this study, magnetic particles (Fe3O4) decorated GO-CMC (Fe3O4@GO-CMC) composite beads were synthesized via the one-pot process and applied for the remediation of phosphate and nitrate from aqueous medium. XRD, BET, SEM, FTIR, EDAX with mapping images and TGA analysis were done on the synthesized beads in order to examine the structural and textural properties. Batch scale adsorption experiments in phosphate and nitrate solution demonstrated the dynamic behaviours of phosphate and nitrate remediation using Fe3O4@GO-CMC composite beads under various experimental conditions such as agitation time, the influence of beads d...
