[Accuracy of blood glucose concentration values outcome performed at various skin sites with personal glucose meters].

Aim: The aim of this study was the comparison of capillary blood glucose values performed at different skin sites with various glucose meters.

Patients And Methods: 50 type 2 - diabetic patients were enrolled into the study. At the first part of study - in stable glucose phase, measurements were performed with four various glucose meters at four skin sites: finger, forearm, abdomen, big toe.

[The picture of visual evoked potentials in type 2 diabetes mellitus].

The aim of this study was to assess frequency of abnormal visual evoked potentials in type 2 diabetic patients and the correlation between patients' age, duration of the disease, metabolic control and coexisting clinical complications on the abnormal recordings. 41 diabetic patients, aged 35 to 62 years were examined. The VEP recordings were performed four times, each time using a pattern made up of elements of another size (18, 36, 72 and 144 angular minutes).

[The picture of visual evoked potentials in type 1 diabetes mellitus].

The aim of this study was to assess frequency of abnormal visual evoked potentials in type 1 diabetic patients and the correlation between patients' age, duration of the disease, metabolic control and coexisting clinical complications on the abnormal recordings. The investigation was carried out in a group of 50 diabetic patients, aged from 16 to 55 years. The VEP recordings were performed four times, each time using a pattern made up of elements of another size (18, 36, 72 and 144 angular minutes).

[Suprascapular nerve entrapment. A case report].

We present a case of a 35 year-old man, an office employee, who got ill when working hard building his own house. At the same time shoulder pain and fever occurred, the latter due to the tooth apical abscess. Several months later atrophy of the left supraspinatus and infraspinatus muscles was found.

[Use of needle electromyography for diagnosis of radiculopathies].

Radiculopathy is sometimes evaluated with needle electromyography as additional examination to radiographic imaging. The purpose of this study was to determine the optimal needle electromyography protocol and the use of needle electromyography in the diagnosis of radiculopathy. The authors analysed English language writings from years 1981-2000.

[Usefulness of visual evoked potentials in visual acuity examination].

Determination of visual acuity by means of VEP is carried out usually by the calculation of the amplitude function response from the value of pattern single element. That purpose is achieved by carrying out several tests of transient VEP performed each time with stimulation, using the pattern of different size of individual elements or changing sweep the following sizes of the pattern single element. Concentration of a patient is necessary during any examination and therefore in clinical practise the second of the listed methods is preferred because of its short duration.

[Intraoperative facial nerve monitoring. Practical remarks].

Objective: Even the most experienced surgeon may have difficulties in identifying and preserving the facial nerve, particularly when the operation is complicated, for example, by size and localization of tumour, trauma or anatomic variations. The aim of this study is to present indications, technics and interpretation of intraoperative facial nerve monitoring.

Methods: This study bases on literature review and our own experience in intraoperative facial nerve monitoring.

[The effect of general anesthesia during operation on the central nervous system on the pattern of somatosensory evoked potentials -- preliminary communication].

During monitoring of somatosensory evoked potentials (SEP) during operation for intracranial aneurysm disappearance of cortical response can alarm the neurosurgeons and suggest the necessity of removal of temporary clipping. As a rule, 50% fall of amplitude and/or 10% prolongation of N13-N20 interlatence are accepted as a criterion for alarming the operating team. However, a considerable part of changes in SEP tracings is caused by factors other than surgical manipulations.
