Wordplay Maps: EASTERN CANADIAN Scramble-towns #1-4

Who would ever have guessed? 

It turns out that an unparalleled word in generating anagrams, i.e. letter scrambles, is P-A-L-I-N-D-R-O-M-E-S. We have taken advantage of that discovery to create this unique series of wordplay maps of imaginary American (and Canadian) locales, each one completed by its official two-letter state (or provincial) abbreviation.

Authors' Note:   Poisoning with sweet-smelling ethylene glycol is a common toxic problem for humans and pets owing to its wide commercial distribution in products including antifreeze and windshield washer fluid.

 Discovered in 1958, denatonium benzoate (sold under various tradenames, including Bitrex), tastes unbearably bitter to most mammals, even in low concentations, but is not apparently harmful otherwise. It has been used to prevent ingestion of a variety of consumer products. In 2012, all American manufacturers of antifreeze voluntarily agreed to add denatonium to these liquids in order to reduce fatal poisonings.

Author's Note:   Anthracycline antibiotics, e.g. doxorubicin (adriamycin) are among the most effective chemotherapy agents; they have been profitably incorporated in multidrug chemotherapy treatment routines for many types of cancer. These advantages are partially offset by a relatively unique adverse effect — the possibility of cardiotoxicity, permanent impairment of the systolic (contracting) function of ventricular heart muscle. 

   Development of this side effect can be minimized by pharmacological manipulations and by monitoring cardiac function periodically during longterm treatment.

   Nuclear medicine techniques have classically been used, but echocardiography may also be of value (see the verse ‘Ejection Fraction’) in monitoring cardiac function.

Authors' Note:

(KEE-layt) / (kee-LAY-shun) Treatment with chelates or chelating agents, has several well-recognized uses in medicine. These include removal of toxic metals from the body, e.g. lead in cases of acute or chronic poisoning, and treatment of iron overload in patients who have received repeated blood transfusions to treat their chronic anemias. The search for drugs of this type which are safer and easier to use is ongoing.

    

  Authors' Note: Erethismus (irritation) mercurialis, synonym for mercurialism, was well-known by Lewis Carroll's time, as signs of chronic poisoning had become common among workers in the hatting industry in which salts of mercury were used in the felting of furs; his character, the 'Mad Hatter' reflects the prevalent stereotype.

In the US, hat-making was centered in the Connecticut town of Danbury, where the majority of long-term workers were subject to the 'Danbury shakes' as well as other neuropsychiatric manifestations. The plant continued in operation, including the dumping of wastewater effluent, until the early 1940s. It closed at that time due to staffing shortages and the need for mercury in the armaments industry.

   In 2020, a study of fish populations in Danbury's Still River showed alarming levels of mercury; the persistence of this toxic residue reflects, in part, the concept of biomagnification. 

Authors' Note: 

(di-JOK-sin)

Digoxin, a cardiac glycoside derived initially from the garden plant digitalis (foxglove), has been used to treat chronic congestive heart failure and to control the heart rate in atrial fibrillation. During the author's professional lifetime, there has been a major reduction in the death-rate and in the incidence of hospital admissions for digoxin poisoning, also known as digitoxicity. This improvement is due to more judicious assessment of factors, e.g. decreasing kidney function, that may result in increasing blood levels of the drug, but also to limitation of the drug's use as alternatives have become available.  

 

Authors' Note:  Occasionally, the shock of reality may help a victim of substance abuse, like Seth, to focus on his plight. A more professional discussion of drug addiction by SheilaB may be enlightening.

Authors' Note:  The toxic effects of illicit moonshine whiskey often result from the solder of car radiators, items that are conveniently incorporated into clandestine distilling equipment. Chronic kidney failure may be a delayed effect of repeated exposure to lead, cadmium and other heavy metals which leach into the brew from this source, allowing 'Whiskey Rick' and his ilk to escape responsibility for the most devastating effects of their concoctions.

Palindromic Poetic Adventures: SPELLING with Palinkus

 

 

Each line in the slide immediately above shows a relevant "magical palindrome". You can learn more about this unique lexical phenomenon (even to its creators it's rather puzzling) by clicking HERE.

Our entire display on this blogpost leads us to the following conclusions about using palindromes for spelling:

1. The "palinku", a form of constrained but "free" (non-rhyming) verse, is a great way to convey ideas. You can find lots more examples of palinku verses on our blog-posts, starting HERE; (they are displayed on the 17th of every month on "Daily Illustrated Nonsense" from 2020 through 2024.)  

2. The information given by palindromes is more misleading than it is helpful.

3. The repetition of the letters in the left and right parts of the phrase or sentence make differentiating between correct and possibly incorrect spellings difficult. 

4. "Magical palindromes" can only overcome a portion of the problem. 

5. Enjoy the rest of your day!

Selected Topics in DIAGNOSTIC IMAGING

CURRENT CONTENTS:

Technetium generators

ECG-gated myocardial SPECT

Parathyroid scintigraphy

A.C. to improve SPECT imaging

DEXA for bone mineral assessment

Fluorine-18 PET (positron emission tomography)

Gadolinium contrast agents for MRI

"DOG"-scans (computed axial DOG-graphy)

Authors' Note:  SPECT (Single Photon Emission Computed Tomography) imaging of the myocardium (heart muscle), performed at rest and with stress (exercise or drug infusion) is currently the most frequent test performed in hospitals' nuclear imaging departments.

   The 3-dimensional images, a type of computed tomography, are produced with a camera which detects the emission of the single-energy gamma rays following an injection of a radionuclide. By connecting the patient to a system for recording the ECG (electrocardiogram), the images can be "gated", i.e. divided into segments of the cardiac cycle; these show contraction of the ventricles, following each of two injections of the imaging agent. A muscle region showing identically poor blood flow (perfusion) and contractile function at rest and stress represents prior heart damage, and is unlikely to respond to therapy.

Authors' Note:   Attacks of renal colic (spasmodic intermittent pain) may occur due to blockage of urine flow by stones in the ureters. In adult patients, stones consisting of calcium salts are most likely. If a high serum calcium level is found (this situation prevails in only a minority of cases of kidney stones), overactivity of the tiny parathyroid (PT) glands may be responsible. Milder cases of excessive parathyroid hormone secretion may also occur without symptoms, but can lead to loss of bone mass and increased risk of bone fracture.

   A single functioning adenoma (benign tumor)  of one of the PT glands is most commonly responsible, but hyperplasia (overgrowth) of all four glands may also result in inappropriate PT hormone secretion, detected by increased blood levels. The radiotracer Tc-99m sestamibi is taken up selectively by overactive PT glands, and may help plan surgery to explore the neck and remove the tumor.

Authors' Note: Absorption of rays by body tissues complicates the interpretation of medical imaging with nuclear techniques. ‘Hybrid' scanners combine the nuclear camera with a CT x-ray unit that provides maps of attenuation; this technique for correction of attenuation (known to workers in the field as A.C.), makes the nuclear scan more accurate in the detection of various lesions, in particular, abnormalities in blood flow to the heart muscle, and studies of deeply-located tumors, e.g. somatostatin scans. 

The combination of the two scanners (nuclear and X-ray CT) has been given the puzzling name “SPECT-CT”. 

 

Authors' Note:   DEXA, or Dual Energy X-ray Absorptiometry, is a simple standardized imaging test to assess bone mass in the context of osteoporosis. It actually measures bone mass in a peculiar form, i.e, mass per unit area (rather than volume) of tissue; differential attenuation (blocking by tissue) for the 2 photons of different energies is assessed for each spatial element in a planar field. The technique is however, excellent for serial tests in the same patient, and is now used  so widely that its results are regarded as synonymous with Bone Mineral Density (BMD).

Authors' Note:   Although the element gadolinium (Gd) is itself toxic, its highly bound chelates make excellent adjunctive agents for diagnostic imaging procedures using magnetic resonance (MR), as they change the magnetic properties of structures with high rates of blood flow, yet allow 'negligible' release of the metal into tissue during the interval following a single intravenous injection. Non-toxic chelates of metallic elements are normally rapidly cleared from the body by urinary excretion. 

    In the late 1990s, a  ‘new’ disease,  nephrogenic systemic fibrosis was found in a small minority of patients, mostly with severe kidney disease, who had received these contrast agents. The problem can be avoided by a simple screening of relevant patients for a history of kidney disease or renal impairment. 

Authors' Note:   The confusing terminology for advanced, i.e. 3D medical imaging, uses acronyms that may be historically based or poorly explained. The development of a method of imaging known as ‘DOGgraphy’ is apocryphal. 

CAT: computerized axial tomography, X-ray imaging of a body section; better described in modern terms as ‘x-ray CT’

PET: positron (dual-photon) emission tomography; a Nuclear Medicine technique involving prior injection of a positron-emitting radionuclide ('isotope'); becoming an important modality in cancer assessment

Holography: processing of fields of light or other radiation scattered from objects; well developed with lasers, but with limited current application in medical imaging.
