Detecting deception: the promise and the reality of voice stress analysis.

Within the past decade a number of so-called voice stress analyzers have been marketed for law enforcement and forensic science purposes. These devices are said to extract from the vocal spectrum a subaudible microtremor signal that is useful in detecting stress in a speaker's voice; thus, it is claimed these devices have great utility as lie detectors and are as accurate as the traditional polygraph instrument. A review of the evidence now accumulated about these devices shows that the evidence for the existence of a microtremor in the voice is problematic and that the capability of these devices in detecting stress is equally questionable. Without exception, however, the scientific evidence reported to date shows that voice stress analyzers are not effective in detecting deception; none of these devices has yet been shown to yield detection rates above chance levels in controlled situations. A brief comparison of voice stress analysis and polygraphic testing as methods of lie detection is made.

[Polyarthrosis of the hand (author's transl)].

The polyarthrosis of the hand is a typical disease of the old age. Its banal form is more frequent in women, its erosive type in men. It can be demonstrated not only on the interphalangeal joints but on the metacarpophalangeal joints as well. The degenerative process of the basal-joints of the first ray of the hand is often seen in polyarthrosis. Most frequently diagnostic problems are caused by the erosive arthrosis however first of all polyarthrosis has to be differentiated from the p.c.p.

[Arthrosis of the first foot segment in aged patients (author's transl)].

Basing on x-ray and clinical examinations, the authors report on the incidence, distribution according to sex and age, and lateral localisation of arthrosis occurring in the first segment of the foot. The bilateral type of arthrosis mostly occurs as a result of hallux valgus and is seen in women. Furthermore, degnerative changes and structural modifications of the dislocated sesamoids are also frequent. Arthrosis associated with hallux rigidus is a degenerative process mainly found in men, which is exclusively unilateral. This degenerative process shows the classical clinical and x-ray signs pertaining to arthrosis

Thyroid antigen associated immune complex glomerulonephritis in Graves' disease.

A 60 year old hyperthyroid black woman with long-standing Graves' disease treated with methimazole presented with anasarca and congestive heart failure. She was found to have the nephrotic syndrome with a urinary protein excretion of 32 g/day. Light and electron microscopy revealed a stage II membranous glomerulopathy. Direct and indirect immunofluorescence demonstrated immunoglobulin G (IgG), immunoglobulin M (IgM), third component of complement and thyroglobulin in a granular diffuse pattern consistent with an immune complex glomerulonephritis. Total thyroidectomy led to a decrease in proteinuria with little change in glomerular filtration rate during an 11 month follow-up period. We believe this to be the first report of immune complex glomerulonephritis associated with thyroid antigen in Graves' disease.

Severe diarrhea secondary to propranolol.

We have described two patients with propranolol-induced severe diarrhea, confirmed by rechallenge with the drug. In both cases the diarrhea was readily reversible with discontinuation of the drug.
