Posted on December 17, by Scott Alexander I. Some old news I only just heard about:
Any history of heart murmur or valve prolapse? The reader suspecting Lyme symptoms should either identify with a number of sections of this article, or, in this absence, be fairly certain of excluding the possibility of Lyme.
Any Doctor investigating prudent treatment for Lyme Disease would do well by reading this essay. Because this is long, those needing a shorter diagnostic tool may scroll up this page for a quick checklist directly above this essay.
Traditionally, the public has been advised to suspect Lyme LD if a round or oval, expanding, red rash develops days after a deer tick bite associated with or followed by a flu-like illness.
This limited Antibiotic essay will apply to only some cases.
The rashes associated with LD can assume a variety of morphologies including vesicular, urticarial, eczematoid or atrophic Acrodermatitis Chronicum Atrophicans. While deer ticks and LD have a well known affiliation, other potential vectors can carry the spirochete that causes LD Borrelia burgdorferi; Bb.
These include, the lone star tick, fleas, the biting flies e. A case of suspected transmission via blood transfusion has Antibiotic essay reported by Dr.
The demonstration of Bb by PCR in two museum mouse specimens dating from Massachusetts and in ticks collected during WW II, provides a mechanism for potential life long exposure and disease which predates the formal discovery of LD.
An occasional patient will date their symptoms which resolved on antibiotic therapy for LD to early childhood.
Before the diagnosis was made, patients would dismiss those symptoms with the statement: That resigned characterization implies that the longevity of the symptoms rules out a reversible cause. Subsequent resolution of the long standing symptoms on antibiotic therapy for LD belies that notion.
Symptoms of LD can begin within days of inoculation with Bb or appear belatedly, but usually in the first to fourth month. Mice innoculated intraperitoneally had Bb demonstrated in the brain on biopsy 12 hours later with a peak at 48 hours Stockholm Conference, If dissemination can occur early, then staging the disease according to the temporal appearance of symptoms may be irrelevant.
Conversely, due to the possibility of symptoms being engendered by chemical mediators and autoimmune reactions by the host against non-viable but immunoreactive DNA blebsorgan dysfunction and attendant symptoms can appear at sites removed from the actual spirochetes.
The diagnostic and therapeutic problems that these phenomenon entail should be obvious.
Rapid dispersion of Bb could lead to the prompt appearance of complications; e. There is no absolutely predictable clinical sequence for LD. The flu-like syndrome may be absent from the initial presentation and may endure once established without treatment.
Cardiac and neurologic complications can be observed sometime within the first 3 months after microbiologically contracting the disease. The onset of complaints can not only be subtle and desultory, but delayed for a year or more. One of my patients denied all LD related symptoms until her husband died, whereupon, a plethora of complaints cascaded into her life beginning that very day.
Moreover, the early constellation of symptoms can have a paucity of findings with unidimensional presentations: Over time, as the untreated LD percolates, symptoms accrue to the burgeoning clinical picture until a multisystem presentation is created.
Other patients can have their manifold symptoms complex develop in the manner of an avalanche. These patterns represent the extremes of a clinical continuum between which there are many variations on the theme ranging from mild to severe disease.
Thus, The failure of a pathognomonic unique and specific presentation to consistently unfold causes sufficient clinical confusion, that a punctual diagnosis is problematic. Therefore, a high index of suspicion is placed at a premium.Topic: Awareness in the fields of IT, Space, Computers, robotics, nano-technology, bio-technology and issues relating to intellectual property rights..
