Table of Contents HIV Test
HIV is the abbreviation for the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome
HIV symptoms which may present in acute HIV infection: These are nonspecific symptoms and can present with other infections; consequently, they are unreliable indicators of HIV infection.
Remember, there is no HIV cure.
HIV window period is the time from HIV infection until a HIV Test can detect any change. Within the HIV window period, the HIV Test would be negative. During this period, the HIV viral load is extremely high, thus making the person highly infectious.
References HIV ELISA (Enzyme-linked immunosorbent assay) test generations:
- 4 weeks after exposure, a negative 4th generation HIV ELISA Test "is very reassuring / highly likely to exclude HIV infection."
- 12 weeks after exposure, a negative 3rd generation HIV ELISA Test "would definitively exclude HIV infection."
References HIV rapid test (20 minutes to results) Two types are available:
- 1st generation: HIV-1 IgG antibody
- 2nd generation: HIV-1 & HIV-2 IgG antibodies
- 3rd generation: HIV-1 & HIV-2 IgG & IgM antibodies
- 4th generation: HIV-1 & HIV-2 IgG & IgM antibodies and HIV p24 antigen
Note: If the clinic attendance is only for the HIV rapid test, then consultation fees are not added.

Individuals are eligible for HIV PEP Treatment if all the following criteria are met:
Prompt antiviral therapy may reduce the risk of HIV transmission by as much as 80%.
- less than 72 hours has elapsed since exposure;
- the exposed individual is not known to be HIV infected;
- the person who is the source of exposure is HIV infected or has unknown HIV status;
- mucous membrane or non-intact skin was exposed to a potentially infectious body fluid;
For optimal efficacy, antiretroviral therapy should be started as soon as possible, ideally within 1 hour of exposure. So that you can remain HIV negative.
The medications and dosages are the same as those used for lifelong treatment of HIV patients. However, for HIV PEP treatment, it is taken for only a month.

Toxoplasma chorioretinitis diagnosed by histopathology in a patient with aids

Conclusion: This case reminds the clinician to consider a broad differential diagnosis for retinal necrosis in immunocompromised hosts and, when serologic and anterior chamber samples are negative, to consider diagnostic vitrectomy for polymerase chain reaction and histopathologic examination.

Analysis of Nanowire Transistor Based Nitrogen Dioxide Gas Sensor-A Simulation Study
Tue, 31 Mar 2015 00:00:00 +0100 | Sensing and Bio Sensing Research
Publication date: Available online 30 March 2015 Source:Sensing and Bio-Sensing Research Author(s): Gaurav Saxena , Roy Paily Sensors sensitivity, selectivity and stability has always been a prime design concern for gas sensors designers. Modeling and simulation of gas sensors aids the designers in improving their performance. In this paper, different routes for the modeling and simulation of a semiconducting gas sensor is presented. Subsequently, by employing one of the route, the response of Zinc Oxide nanowire transistor towards nitrogen dioxide ambient is simulated. In addition to the sensing mechanism, simulation study of gas species desorption by applying a recovery voltage is also presented. (Source: Sensing and Bio Sensing Research)
Clinician-Patient Risk Discussion for Atherosclerotic Cardiovascular Disease Prevention Importance to Implementation of the 2013 ACC/AHA Guidelines
Mon, 30 Mar 2015 18:55:41 +0100 | Journal of the American College of Cardiology
Successful implementation of the 2013 American College of Cardiology/American Heart Association cholesterol guidelines hinges on a clear understanding of the clinician-patient risk discussion (CPRD). This is a dialogue between the clinician and patient about potential for atherosclerotic cardiovascular disease risk reduction benefits, adverse effects, drug-drug interactions, and patient preferences. Designed especially for primary prevention patients, this process of shared decision making establishes the appropriateness of a statin for a specific patient. CPRD respects the autonomy of an individual striving to make an informed choice aligned with personal values and preferences. Dedicating sufficient time to high-quality CPRD offers an opportunity to strengthen clinician-patient relations...
