Papillon Lefevre syndrome: bridge between Dermatologist and Dentist
2010
Papillon-Lefevre syndrome is a rare autosomal recessively inherited condition which shows features common to both dentistry and dermatology. This disease is characterized by palmoplantar hyperkeratosis and severe periodon- titis. Therefore both the dentist and the dermatologist should be aware of the same because an early diagnosis of the syndrome can help to preserve the teeth by early institution of treatment, using a multidisciplinary approach. Here we present a case report of Papillon-Lefevre syndrome, along with a comprehensive review of the etiology, pathology, clinical features, differential diagnosis and management of the condition.

Precapillary Servo Control of Blood Pressure and Postcapillary Adjustment of Flow to Tissue Metabolic Status
1996
Background There are several shortcomings in current understanding of how the microvasculature maintains tissue homeostasis. Presently unresolved issues include (1) integration of the potentially conflicting needs for capillary perfusion and hydrostatic pressure regulation, (2) an understanding of signal transmission pathways for conveying information about tissue energetic status from undersupplied tissue sites to the arterioles, (3) accounting for the experimentally observed interrelations between precapillary and postcapillary resistances, and (4) an explanation of how precise local adjustment of perfusion to metabolic demands is achieved. Methods and Results A novel conceptualization o…
Papillomatosis Gougerot und Carteaud als ektodermale Randsymptomatik bei segment�rer Lipodystrophie
1963
Beschreibung einer Gougerot-Carteaudschen Papillomatose, die bisher ausschlieslich im Bereiche einer segmentaren Fettverteilungsstorung nach Art der progressiven Lipodystrophie zur Ausbreitung gekommen ist. Unter Hinweis auf annahernd vergleichbare Hautbegleiterscheinungen bei anderen vorzugsweise mesenchymalen Konstitutionsabweichungen (z. B. dem Marfan- oder dem Ehlers-Danlos-Syndrom) werden die papillomatosen Veranderungen als ektodermale Randsymptome gewertet.
EXPERIENCE OF REMOVING BENIGN NEOPLASMS OF SKIN IN CERVICOFACIAL AREA USING THE METHOD OF PLASMA ABLATION
2017
Choosing appropriate methods for removal of benign skin lesions (BSL) in the cervicofacial area has always been an important and challenging issue. Removal of the BSL is indicated and performed for medical and aesthetic reasons. A method with less painful procedures, a short healing period, without noticeable long-lasting traces (such as scars, dyschromia) and, predictably, fewer repeat procedures is preferred. Objectives. Evaluation of the effectiveness, safety and convenience of BSL plasma ablation using Plexr® (GMV, Italy); Comparison of the reparative processes speed after the BSL removal in the cervicofacial area applying the Plexr® device with other instrumental methods (based on lite…
Myogenic effects enhance norepinephrine constriction: Inhibition by nitric oxide and felodipine
1998
Myogenic effects enhance norepinephrine constriction: Inhibition by nitric oxide and felodipine. Myogenic, pressure-induced vasoconstriction may amplify the effects of circulating vasoconstrictors. Through intravital microscopy in cremaster arterioles (31 to 115 μm diameter), the relative contribution of myogenic responses (MR) to norepinephrine (NE)-induced constriction and the inhibitor potency of nitric oxide (NO) or a Ca2+ entry blocker (CEB), felodipine (F), were examined. In 24 anesthetized hamsters, a vessel occluder was placed around the aorta to control cremaster vessel inflow pressure (IP). NE infusion increased blood pressure (by 50 ± 2mm Hg) and induced significant constriction …
Brimonidine versus dapiprazole: Influence on pupil size at various illumination levels.
2005
To evaluate the influence of dapiprazole versus brimonidine on pupil size at various illumination levels.Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany.In randomized prospective study, 19 healthy volunteers received 2 ophthalmic solutions, dapiprazole and brimonidine, 1 in each eye, for intraindividual comparison. Before and after application, pupil diameter was measured using an infrared binocular pupillometer at 3 illumination levels (0.03, 0.82, and 6.4 lux).Only slight pupil dilation was observed under scotopic conditions after application of both agents. After 20 minutes, the median reduction in pupil width was 1.4 mm for brimonidine and 0.9 mm for dapiprazo…
The pupillary response to mental overload
1977
The hypothesis that the pupil constricts below base level in situations of mental overload was tested. Subjects had to perform in a four-alternative forced-choice task at 75%, 100%, and 125% the speed of their maximum processing capacity. No indication of a pupillary constriction in the overload situation was found. The pupil dilated under all three conditions. The pupil diameter of male subjects significantly decreased after the sharp increase at the beginning of the experimental phases, while the female subjects’ pupil diameter remained at the same level after the initial increase. The amount of dilation depended on information load for male subjects only. Results were taken as further in…
Effect of Phenylephrine on the Accommodative System
2016
Accommodation is controlled by the action of the ciliary muscle and mediated primarily by parasympathetic input through postganglionic fibers that originate from neurons in the ciliary and pterygopalatine ganglia. During accommodation the pupil constricts to increase the depth of focus of the eye and improve retinal image quality. Researchers have traditionally faced the challenge of measuring the accommodative properties of the eye through a small pupil and thus have relied on pharmacological agents to dilate the pupil. Achieving pupil dilation (mydriasis) without affecting the accommodative ability of the eye (cycloplegia) could be useful in many clinical and research contexts. Phenylephr…
Optic neuropathy caused by type A botulinic toxin
2014
Purpose To report the development of an optical neuropathy after injection of type A botulinic toxin in a subject with blepharospasm. Methods Optical neuropathy was evaluated through a complete ophthalmologic examination consisting of bio-microscopy, tonometry and study of visual sharpness, colour test, visual field, OCT, fluorangiography and determination of VEPs. Results Intravenous therapy was begun with Metilprednisolone (20 mg/Kg/day) and Vitamin B6 associated with oral Citicoline, and there was a clear improvement down to normalization of the symptoms. After 6 months the Humphrey computerized visual field with central 30-2 program threshold test emphasised in ODx an upper half-field a…
