[The analysis of DNA amplified fragment length polymorphism in forensic identification expertise: the possible sources of errors under nonoptimal conditions for the polymerase chain reaction].

Analyses the effects of nonoptimal conditions of polymerase chain reaction concerning the initial amount of matrix DNA and duration of its amplification on the amplification picture of hypervariable tandem-arranged locuses of human genome. Shows the causes of its possible ambiguous interpretation leading to inadequate expert conclusions in forensic gene-identification expert evaluation. Outlines the approaches to solution of this problem.

[Pulmonary metastasizing of prostatic carcinoma--source of errors in the ambulatory x-ray examination of lungs].

It is reported on eight patients with a primary carcinoma of the prostatic gland who were admitted to the hospital for clinical clarification of conspicuous pulmonary findings. The radiological findings of a general radiograph of the thorax are multiform and for themselves alone they do not permit an etiological coordination. For this reason the demand can be derived in patients of the adequate age group with tumour symptomatology can also be thought of a carcinoma of the prostatic gland and already during the examination in the outpatient department to carry out a palpatory examination and, if possible, to make a general radiograph of spinal column and pelvis, since in these cases the diagnosis can be made already before admission.

Sources and control of error in industrial hygiene measurements.

Many sources of error exist in industrial hygiene measurements. Errors may be systematic or random. Eliminating or controlling systematic and random error during measurement, analysis, and data interpretation is a matter of aggressive quality control/quality assurance and appropriate statistical treatment of data. The occupational health care professional should be aware of error sources in industrial hygiene measurements and be on the lookout for flawed exposure estimates.
