[Effect of road traffic noise on sleep. A paired comparison between sleep polygraphic parameters recorded in a noisy apartment along a road with heavy traffic and those recorded in a quiet suburban house].

Effects of road traffic noise on sleep were studied comparing 15 sleep polygraphic parameters and 6 subjective sleep complaints in a noisy apartment with those in a quiet house. Subjects were 8 persons (5 young men aged 19-38, one woman aged 65 and 2 men aged 66) and were studied for 76 nights. The average equivalent sound pressure level (Leq) from 10 p.m. to 7 a.m. was 46.67 dB (A) in the noisy apartment's bedroom compared to 27.72 dB(A) in the bedroom of the quiet house. Of the 15 parameters, proportion of REM sleep for the younger subjects was significantly less (p = 0.0046, paired t-test) in the apartment compared to the quiet house. No significant difference was seen in the remaining 14 parameters between the apartment and the house. Of the 6 subjective sleep complaints, "awakened early in the morning," was significantly less for young subjects (p = 0.031, Two-tailed sign test) in the apartment than in the house. There was no significant difference seen for the older subjects in the 6 subjective sleep complaints and 15 sleep polygraphic parameters between the two places. It appears that a small difference in the effect of road traffic noise on sleep between young and old may exist.

Additional records of nematode parasites from Papua New Guinea amphibians with a list of recorded endohelminths by amphibian hosts.

An examination of a small sample of four species of frogs (Cophixalus riparius, Phrynomantis humicola, Ph. stictogaster, Ph. wilhelmana) from Papua New Guinea yielded altogether 5 species of nematodes, 2 of them being new to science. These include: Cosmocercella phrynomantisi sp. n. (type host Ph. humicola), Spinicaudinae gen. sp., Parathelandros andersoni sp. n. (type host C. riparius), Oswaldocruzia bakeri, and Paracapillaria spratti. C. phrynomantisi sp. n. differs from congeneric species mainly in the length of spicules (0.180 mm) and the character, arrangement and number of caudal papillae in the male, while P. andersoni sp. n. is characterized mainly by the presence of four well developed spines on the male tail. Pseudocapillaria spratti is redescribed in detail and it is transferred to Paracapillaria as P. spratti (Moravec et Sey, 1986) comb. n. Capillaria combesi Chabaud et Knoepffler, 1985 is transferred to Amphibiocapillaria Moravec, 1982 and Capillaria petiti Justine et Bain, 1987 to Pseudocapillaria Freitas, 1959. A survey of the endohelminths (excluding Hirudinea) hitherto reported from New Guinea amphibians is presented.

[Diagnostic value of R amplitude behavior at a recording site below the conventional thoracic wall recording in the diagnosis of chronic ischemic heart disease].

Sensitivity and specificity of the behaviour of the R-amplitudes under exercise are investigated at an additional lead position on the anterior chest wall, which in previous multi-electrode-examinations showed a higher sensitivity than the conventional Wilson-leads V 4 and V 5. For the criterion "increase of R-amplitudes" could certainly be confirmed a higher sensitivity at the additional lead position, the bad specificity both at the conventional and at the additional lead position allows, however, only the inclusion of the decrease of the physiological R-amplitude into the exclusion diagnostics of the chronic ischaemic heart disease.
