Bursaphelenchus mucronatus (Nematoda: Parasitaphelenchidae) associated with Monochamus galloprovincialis from Bosnia and Herzegovina and Georgia.

Bursaphelenchus mucronatus was detected in association with the pine sawyer beetle (Monochamus galloprovincialis) during the implementation and testing of cross traps with insect attractants as an efficient tool for detection survey for pine wood nematode (Bursaphelenchus xylophilus) in Bosnia and Herzegovina and Georgia in 2017 and 2018, respectively. This nematode was characterized by morphological, morphometric and molecular features. This is the first report of B. mucronatus in association with a M. galloprovincialis in Bosnia and Herzegovina and in Georgia.

Redescription of Diastolaimus grossus (Truskova & Eroshenko, 1977) Andrássy, 1984 (Rhabditida, Chambersiellidae) from Europe and comments on its phylogenetic position.

Two populations of the species Diastolaimus grossus have been obtained from bark of trees in Bosnia and Herzegovina and the Czech Republic. The species is described and characterized in detail using morphological techniques (light and electron scanning microscopy) and morphometrical (Gower General Similarity coefficient of morphological characters) and molecular analyses, including phylogenetic analysis of all related and already sequenced species of the family Chambersiellidae. Morphological and molecular analyses, based on 18S and 28S ribosomal DNA sequences, show that the family Chambersiellidae is polyphyletic, being the subfamily Chambersiellinae related with Cephalobomorpha and Tylenchomorpha, and the subfamily Macrolaiminae is located into Panagrolaimomorpha. The genus Diastolaimus, previously belonging to Macrolaiminae, is transferred to Chambersiellinae. Diastolaimus mexicanus is proposed as a junior synonym of D. grossus.

Redescription of Macrolaimus canadensis Sanwal, 1960 and M. ruehmi Andrássy, 1966 (Nematoda, Rhabditida, Chambersiellidae), and new data on M. crucis Maupas, 1900.

Three species belonging to the genus Macrolaimus, namely M. canadensis, M. crucis and M. ruehmi, have been obtained from areas of natural vegetation in Bosnia and Herzegovina, Corsica (France), the Czech Republic and Spain. These three species are characterized by the body length of males and females, stomatal proportion of the gymnostom and cheilostom, excretory pore position, postvulval uterine sac length, male and female tail length and morphology, and the length and morphology of the spicules and gubernacula. The occurrence of M. crucis in Spain has, as a result of this study, now also been expanded to a larger area of the southern Iberian Peninsula. Morphological and morphometrical analyses showed that M. canadensis and M. ruehmi are very similar, sharing apomorphic characters. In contrast, M. crucis has plesiomorphic characters. Description, measurements and illustrations are provided for these three species.

[Behavioral rehabilitation of nonspecific symptoms occuring after craniocerbral trauma (author's transl)]. / Verhaltenstherapeutische Rehabilitation nach Schädelhirntrauma.

The purpose of this study was to develop a behavioral rehabilitation program for patients with long-term nonspecific symptoms following craniocerebral trauma. In 47 patients we analyzed symptoms typical of "illness behavior" (e.g. complaining tendency, depression, irritability, psychosomatic pain, problems in job performance and social interaction) as possible targets for behavior modification. We then developed a behavioral training program to teach the patients various techniques of self-control (relaxation, desensitization, self-image training, analysis and control of illness behavior, assertiveness, performance techniques), our program being based on studies in the U.S.A. using similar approaches. For a preliminary testing two groups of 8 and 6 patients each were treated by different therapists. The patients worked through a section of the program manual prior to each group session. During the sessions proper (a total of 8 weekly two-hour sessions) the different techniques were practiced under the therapist's supervistion. In both groups a significant reduction in illness behavior as indicated on questionnaires and in 3-month follow-up was found. These encouraging results need to be further substantiated by controlled outcome studies.
