Venous sinus thrombosis after Proteus vulgaris meningitis and concomitant Clostridium abscess formation

A 19-y-old woman presented with Proteus vulgaris meningitis as a complication of chronic otitis media. Despite treatment with ceftazidime and amikacin no clinical improvement was observed. Cranial MRI revealed right-sided mastoiditis/otitis media and venous sinus thrombosis. After mastoidectomy, repeat cranial MRI demonstrated abscess formation in the venous sinuses. The abscess was drained. Clostridium spp. was isolated from the abscess culture.     

Distraction histogenesis of the maxillofacial region

The changes in the surrounding soft tissues during long bone distraction in orthopedic surgery have been the subject of several reports, studies on changes in the craniofacial region, in which various tissues, including the skin, muscle, tendon, blood vessel, and gingiva are rare. Therefore, there is a need for studies on the soft tissue aspects of bone lengthening of the craniofacial region. The aim of this review was to address this issue by reviewing the literature about the distraction histogenesis of various tissues, including skin, muscle, blood vessel, nerve, and gingiva.     

Laughter as a social rejection cue: Gelotophobia and transient cardiac responses to other persons' laughter and insult

Other persons' laughter, normally perceived as a signal that persons are friendly and inviting others to approach, can also be perceived as a cue of social rejection. In this study, prerecorded laughter was placed in a realistic and personally relevant context, and participants' responses were related to gelotophobia, a trait predisposing to perceiving laughter as a cue of social rejection. Individuals with gelotophobia showed marked heart rate deceleration in response to the laughter stimulus, possibly indicating a “freezing‐like” response. Moreover, cardiac responses to anger provocation by overtly insulting statements indicated heightened aggressive anger in response to cumulated social threat. The study adds to recent research showing specific cardiac responses to social rejection and to the literature on social rejection sensitivity by demonstrating the value of using well interpretable physiological measures in this research context.     

Is auditory function affected after Le Fort I osteotomy?

The aim of this study was to evaluate changes to the Eustachian tube and middle ear function and hearing level in individuals undergoing Le Fort I osteotomy. 20 consecutive patients underwent Le Fort I maxillary osteotomy with advancement, impaction or a combination of both. All individuals underwent hearing sensitivity tests, including pure tone audiometry and acoustic impedance measurements (middle ear pressure and compliance), which were carried out by an audiologist 1 week before surgery (t(0)), and then again 1 week (t(1)) and 4 weeks (t(2)) after surgery. Regarding pure tone audiometry, the differences between t(0) and t(2) at a frequency of 125Hz (P=.002), between t(0) and t(1) and between t(0) and t(2) at a frequency of 250Hz, and between t(0) and t(1) at a frequency of 1000Hz (P=.006) were statistically significant. There was no statistically significant difference at any other frequency. Regarding middle ear pressure, no statistically significant difference was observed between t(0) and t(1), and t(0) and t(2). Following Le Fort I osteotomy, mild changes in hearing sensitivity and middle ear pressure are possible, but these changes were clinically insignificant.     

Atypical presentation of primary giant nasal septal mucopyocele

Mucoceles are expansile, encapsulated, benign cystic lesions with the potential for adjacent bony remodeling and resorption. Previous nasal surgery, recurrent infections, allergies, and facial traumas are all possible causes of mucoceles involving mainly paranasal sinuses. When the mucocele is infected, it is referred to as mucopyocele. Nasal septal mucoceles seen in only very seldom cases might develop from pneumatized and infected nasal septa. In the current article, we present an interesting primary giant septal mucopyocele that destroys all paranasal cells as a tumoral lesion. The perpendicular plate of ethmoidal bone, vomer, and bilateral anterior and posterior ethmoidal cells were destroyed by mucopyocele. The nasal cavity was totally obstructed by lesions on both sides. On the left side, the lesion also eroded the left lateral nasal wall causing external swelling at the medial canthal region. This is the first case of a giant septal mucopyocele of its kind in the literature. Although nasal septal mucocele is very rare, it should be considered in differential diagnosis of intranasal masses.
