Összefoglaló. A Treacher Collins-szindróma a mandibulofacialis dysostosisok csoportjába tartozó kórkép. Főbb jellegzetességei a maxillaris és mandibularis dysostosis, az antimongoloid szemrések, az alsó szemhéj colobomája, illetve a vezetéses halláscsökkenés. A szindrómával járó tünetek egyénenként és családon belül is nagyon eltérőek lehetnek; legenyhébb formái csaknem észrevehetetlenek, míg a súlyosabb esetekben az életet veszélyeztető légúti szövődmények léphetnek fel. Hátterében az esetek döntő többségében a TCOF1-gén eltérései játszanak szerepet, mely eltérések autoszomális domináns módon öröklődnek. Esetbemutatásunk célja, hogy felhívjuk a figyelmet a genetikai vizsgálat elvégzésének fontosságára olyan, klinikailag jól felismerhető tünetegyüttes, mint a Treacher Collins-szindróma esetén. Bár a betegség a klinikai kép alapján diagnosztizálható, az ismétlődés kockázatát csak úgy tudjuk pontosan meghatározni, ha ismerjük a családtagok genotípusát. A bemutatott család több tagjánál kimutatható volt a TCOF1-gén mutációja, annak ellenére, hogy klinikai tünetük nem volt. A jelenség magyarázata az inkomplett penetrancia, azaz a hibás gén fenotípusosan nem kerül kifejeződésre. Orv Hetil. 2020; 161(52): 2201–2205. Summary. Treacher Collins syndrome belongs to the group of mandibulofacial dysostoses. Its main features are maxillary and mandibular dysostosis, downward-slanting palpebral fissures, coloboma of the lower eyelid and conductive hearing loss. The symptoms associated with the syndrome can vary greatly from individual to individual and within the family. In its mildest form, the syndrome is almost imperceptible, and when severe, life-threatening respiratory complication can occur. TCOF1 is the major gene involved with an autosomal dominant mode of inheritance. The purpose of our case study is to draw attention to the importance of performing genetic testing in a clinically recognizable disorder such as Treacher Collins syndrome. Although the disease can be diagnosed based on the clinical symptoms, the risk of recurrence can only be accurately determined if the genotype of the family members is known. Several members of the presented family had a mutation in the TCOF1 gene despite having no clinical symptoms. The explanation for this phenomenon is incomplete penetrance, i.e., the defective gene is not expressed in the phenotype. Orv Hetil. 2020; 161(52): 2201–2205.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.
