ABSTRACT
Objectives. This study attempts to confirm the hypothesis that transcutaneous electrical stimulation (TENS) of peripheral Aß fibers inhibits nociceptive processing, by quantifying the change of laser-evoked potential (LEP) components, using a 980-nm diode laser. Materials and Methods. Cutaneous heat stimuli were delivered to the dorsum of the right hand in 13 volunteers. LEPs and pain intensity ratings were recorded before, during, and after the use of TENS (110 Hz) at the dorsolateral forearm. Area under the curve (AUC), LEP amplitudes (N2P2), and peak latencies (N2, P2) were calculated. The paired samples t-test was used for statistical analysis. Results. A significant reduction of LEP amplitudes and AUC was found during and after the use of TENS (p < 0.05). After 10 min of TENS this was associated with a clinically relevant decrease of pain intensity. Conclusions. Our data suggest that TENS inhibits nociceptive processing. Ten minutes of TENS exerts a clinically relevant pain reduction.

An electronic nose has been used to classify blockmilk products subjected to various heating processes based on their volatile composition. Multivariate analyses of electronic nose and GC/MS data are highly comparable with respect to relative changes in aroma profile going from raw to final product. Predictive properties of various neural networks based on the raw sensor output were moderate to good.

The successful treatment of a brachial artery occlusion caused by a chronic embolizing aneurysm of the anterior humeral circumflex artery is described. In the case of embolizing axillary artery aneurysms, the best therapy is resection of the aneurysm followed by distal thromboembolectomy and vascular reconstruction by a saphenous vein segment. Prosthetic material should be reserved as a second choice. In this particular case successful therapy consisted of ligation of the anterior humeral circumflex artery proximal and distal to the aneurysm, resection of the aneurysm, and transcubital thromboembolectomy.

An epidemiological survey of the Korsakoff syndrome was made in The Hague, The Netherlands, by interviewing workers of all relevant health care organisations in that city. A prevalence of 4.8 per 10,000 inhabitants was found. The mean age of patients was 62 years. Seventy-five percent of all patients had already been hospitalised for several years. Physical and mental health, as judged by other medical diagnoses, was poor.

The authors present a series of 50 patients for which a laparotomy was performed following a lesion of the intestines due to radiotherapy. Resection and anastomosis is indicated only in localized lesions in patients with a good general state. In more extensive bowel lesions it is safer to perform by-pass procedures as the morbidity and postoperative mortality are lower. However, by-pass is inadequate to stop profuse haemorrhages: in such cases resection is mandatory.
