Rare craniofacial clefts.

I present a review of the pattern of rare craniofacial clefting in patients presenting to a tertiary referral craniofacial unit. Patients with an isolated rare cleft were uncommon; most had multiple axes of disruption. Midline and paramedian facial clefts, although occasionally occurring alone, often overlap with adjacent facial clefts and extend along an upward cranial axis. The corresponding midline and paramedian facial clefts were never seen in isolation but were almost always seen with their axial downward cleft. Lateral nasal, oro-ocular, and lateral forehead clefts showed diffuse and often poorly defined regions of disruption, resulting in a multiplicity in clefts. The small subgroup of patients with features of the amniotic band sequence had more and differently distributed clefts compared with the larger nonamniotic band group.     

Structure and culture of schools of public health to support academic public health practice.

Schools of public health have been cautioned about producing graduates and research that were disconnected from public interest. Although institutions may implement a variety of strategies to rectify the situation, institutional structural and cultural barriers impede progress. Public health practice coordinators in accredited schools of public health were surveyed to describe the presence of structural and cultural barriers to academic public health practice using the Stevens model. Administrative leadership and faculty reward systems are described as critical to advance academic public health practice.     

Extracranial approaches to the repair of cerebrospinal fluid rhinorrhea.

This paper presents a review of the extracranial evaluation and treatment of cerebrospinal fluid (CSF) rhinorrhea. Diagnosis with attention to a careful history and physical with maneuvers which exacerbate drainage and thorough physical exam along with imaging techniques are discussed. The common etiologies of CSF rhinorrhea including trauma, spontaneous leakage, tumor, and iatrogenic injury are included. Management consists of conservative measures including the avoidance of straining maneuvers which increases intracranial pressure. Periodic drainage of CSF via lumbar puncture or continuous drainage via flow-regulated systems may also be of benefit in attempts of conservative management. Failure of conservative management, constant leakage, pneumocephalus, and recurrent meningitis are indicators for surgical repairs. Ethmoid-cribiform plate region repairs are generally approached by external ethmoidectomy and the development of mucoperiosteal flaps from various donor sites which are then rotated to the leak area to seal the defect. Frontal sinus leaks are usually repaired via an osteoplastic flap technique with direct repair of the dural defect or the use of fascial graft tucked under the bony defect, then obliterated with abdominal fat. CSF rhinorrhea presents a diagnostic and surgical challenge to the otolaryngologist. After diagnosis and localization, operative repair using extracranial approaches is accepted as the initial method of intervention in these cases.     

Xp Microdeletion Syndrome Characterized by Pathognomonic Linear Skin Defects on the Head and Neck

Abstract: We describe a new case of a rare syndrome characterized by ocular abnormalities and pathognomonic linear skin defects. This syndrome is the result of an unbalanced translocation resulting in a deletion of the distal end of the short arm of the X chromosome. We report the thirteenth case and review the clinical and cytogenetic aspects of this disorder. In addition we discuss new findings pertaining to the histopathology of the skin lesions.     

Coronary vasoconstriction in vitro in the hearts of polyarthritic rats: effectiveness of in vivo treatment with the endothelin receptor antagonist SB 209670.

Here we demonstrate that perfused hearts removed from polyarthritic rats develop a pronounced coronary vasoconstriction ex vivo. This vasoconstriction is almost entirely blocked by in vivo pretreatment of the rats with the endothelin receptor antagonist, SB 209670. Thus, inflammatory states may be associated with an increased activity of the endothelin system, leading to vascular dysfunction and vasoconstriction.     

Aquatically acquired Aeromonas hydrophila wound infection. A report of 3 cases

The occurrence of Aeromonas hydrophila wound infections in healthy hosts after water-associated injury is being reported more frequently. This paper reports our experience with 3 such cases and outlines the importance of recognising the association between a water-related injury and this organism.
