Psychopathologic and zoological aspects of acarophobia.

Acarophobia represents a nosologically inconsistent psychiatric clinical picture which is exceptional in that it is noticed among the clientele of those in charge of pest control, hygienists, health department medical officers and dermatologists rather than in psychiatric practice or mental hospitals. Apart from acarophobia in the course of schizophrenic, affective and organic psychoses as well as cases in which the phobia was induced by another individual, roughly half of the cases were 'pure' forms, i.e.

Nosocomial myiasis.

When the larvae of flies invade man the clinical picture is referred to as 'myiasis'.

A 32-year-old man was accused of attempted rape. While urinating at the side of the road he felt an erection. He approached a 9-year-old girl who happened to be coming along and pressed his penis between her legs until ejaculation.

[Proprioceptive deficit following cruciate lesions--afferent disorder or compensatory mechanism?].

It was suggested that the ACL has not only mechanical functions but also acts as proprioceptive organ. In cruciate deficient knees pathological patterns of muscle control were found. These findings could be caused by a disturbed afferent signal from the disrupted ACL or by secondary changes in muscle innervation, which shall protect the instable knee against subluxation.

Changes in muscular activity after knee arthrotomy and arthroscopy.

The object of this study was to find out whether an arthrotomy of the knee would damage joint proprioception. Twenty patients who underwent arthrotomy, and 20 patients after arthroscopy, were tested on a modified ergometer and the electromyographic action of their quadriceps and hamstrings recorded. The quadriceps action started later and had a shorter duration (20 ms) after arthrotomy.
