INTRODUCTION: Angiomyxolipoma (AML) is a rare variant of benign lipoma with characteristic histopathological and immuno-histochemical features. It consists of fatty tissue admixed with myxoid stroma and blood vessels. It was first described by Mai et al. in 1996 [1], with a total number of 19 cases reported since. PRESENTATION: This is the first report of an AML in subcutaneous tissue of the face, presenting as a 4-month old cystic lesion in a 78-year old lady. Diagnosis was based on radiological and histopathological with cytochemical findings...

BACKGROUND: Immobilization of the cervical spine is a cornerstone of spinal injury management. In the context of suspected cervical spine injury, patients are immobilized in a 'neutral position' based on the head and trunk resting on a flat surface. It is hypothesized that the increased thoracic kyphosis and loss of cervical lordosis seen in elderly patients may require alternative cervical immobilization, compared with the 'neutral position'. METHODS: To investigate this, an audit of pan-scan CT performed on consecutive major trauma patients aged over 65 years was carried out over a 6-month period...

BACKGROUND/AIMS: Surgical treatments for the correction of congenital ptosis with poor levator function, including frontalis suspension or maximal levator resection, remain controversial. We evaluated the postoperative surgical and cosmetic outcomes after maximal levator resection for unilateral congenital ptosis with poor levator function. METHODS: A retrospective, interventional case series was performed. A total of 243 patients with 243 eyelids (210 unilateral and 33 bilateral asymmetric ptosis) who underwent unilateral maximal levator resection were included...

BACKGROUND: Recent experimental studies have revealed that n-3 fatty acids, such as eicosapentaenoic acid (EPA) regulate postprandial insulin secretion, and correct postprandial glucose and lipid abnormalities. However, the effects of 6-month EPA treatment on postprandial hyperglycemia and hyperlipidemia, insulin secretion, and concomitant endothelial dysfunction remain unknown in patients with impaired glucose metabolism (IGM) and coronary artery disease (CAD). METHODS AND RESULTS: We randomized 107 newly diagnosed IGM patients with CAD to receive either 1800 mg/day of EPA (EPA group, n = 53) or no EPA (n = 54)...

This article evaluates the effect of upper eyelid blepharoplasty on eyelid margin position and brow height. This study is a retrospective analysis of patients who underwent upper eyelid blepharoplasty without concurrent blepharoptosis repair or brow surgery. The medical records of the participants were retrospectively reviewed and an established image analysis software was used to quantify the upper margin reflex distance (MRD1) as well as brow height using high quality standardized clinical photographs. A total of 19 patients (38 eyelids and brows) met the inclusion criteria...

BACKGROUND: Facial paralysis has a profound impact on the brow, and currently static procedures are the mainstay of treatment. The deep temporal branches of the trigeminal nerve, given their proximity to the brow, may serve as possible donor nerves for both potential innervation of a free muscle transfer in patients with prolonged facial palsy or nerve transfers in acute or subacute palsy. As such, the authors present the detailed surgical anatomy of the deep temporal nerve, assessing feasibility for both functional muscle and nerve transfers, including a proposed surgical technique...

Generalist parasites exploit multiple host species at the population level, but the individual parasite's strategy may be either itself a generalist or a specialist pattern of host species use. Here, we studied the relationship between host availability and host use in the individual parasitism patterns of the Shiny Cowbird Molothrus bonariensis, a generalist avian obligate brood parasite that parasitizes an extreme range of hosts. Using five microsatellite markers and an 1120-bp fragment of the mtDNA control region, we reconstructed full-sibling groups from 359 cowbird eggs and chicks found in nests of the two most frequent hosts in our study area, the Chalk-browed Mockingbird Mimus saturninus and the House Wren Troglodytes aedon...

In many species, male secondary sexual traits have evolved via female choice as they confer indirect (i.e. genetic) benefits or direct benefits such as enhanced fertility or survival. In humans, the role of men's characteristically masculine androgen-dependent facial traits in determining men's attractiveness has presented an enduring paradox in studies of human mate preferences. Male-typical facial features such as a pronounced brow ridge, a more robust jawline may signal underlying health while beards may signal men's age and masculine social dominance...

The small nuclear RNA (snRNA) components of the spliceosome undergo many conformational rearrangements during its assembly, catalytic activation and disassembly. The U4 and U6 snRNAs are incorporated into the spliceosome as a base-paired complex within the U4/U6.U5 small nuclear ribonucleoprotein (tri-snRNP). U4 and U6 are then unwound in order for U6 to pair with U2 to form the spliceosome's active site. After splicing, U2/U6 is unwound and U6 annealed to U4 to reassemble the tri-snRNP. U6 rearrangements are crucial for spliceosome formation but are poorly understood...

BACKGROUND: Facial burns represent between one-fourth and one-third of all burns. The long-term sequelae of periorbital burns include significant ectropion and lagophthalmos as a result of secondary burn contractures in the lower and upper eyelids, in addition to complete or incomplete alopecia of the eyebrows. METHODS: A retrospective study of 14 reconstructive procedures for 12 postburn faces was conducted with all procedures performed since 2010 at the Department of Plastic Surgery, Al-Hussein University Hospital, and at the Craniofacial Unit, Nasser Institute Hospital...

PURPOSE: Brow ptosis commonly occurs with aging. Minimally invasive techniques are varied and include neurotoxin paralysis of eyebrow depressors and internal brow pexy. The authors present a modification of the traditional brow-pexy surgery which incorporates weakening of the lateral eyebrow depressor, the orbicularis oculi muscle, to synergistically influence brow position. METHODS: This retrospective review includes 44 brows in 22 patients treated over a 14-month period...

BACKGROUND: As the ptotic brow drops below the supraorbital rim, it can exacerbate dermatochalasis by pushing the adjacent skin of the upper lid further down. AIM: The purpose of this study was to evaluate the outcomes associated with a combined pretrichial brow lift and upper lid blepharoplasty in patients with dermatochalasis and mild to moderate brow ptosis. MATERIALS AND METHODS: A retrospective case series of 46 patients with dermatochalasis and mild to moderate brow ptosis treated with a combined, bilateral pretrichial brow lift and upper lid blepharoplasty from January 2008 to December 2011...

Soft tissue deflation and descent have long been implicated in the pathogenesis of facial aging. In the periorbital area, the upper orbital region is thought to change by descent of the eyebrow, as well as deflation of brow fat. While the understanding of the aging changes in the upper eyelid region are relatively simple, the lower eyelid poses a myriad of aging changes, each demanding a specific management plan. These can be best described in terms of elevations, or 'Hills' and hollows, or 'Valleys'. This article simplifies the understanding of the lower eyelid in the light of anatomical knowledge, and available literature...

Ungulates are leading drivers of plant communities worldwide, with impacts linked to animal density, disturbance and vegetation structure, and site productivity. Many ecosystems have more than one ungulate species; however, few studies have specifically examined the combined effects of two or more species on plant communities. We examined the extent to which two ungulate browsers (moose [Alces americanus]) and white-tailed deer [Odocoileus virginianus]) have additive (compounding) or compensatory (opposing) effects on herbaceous layer composition and diversity, 5-6 years after timber harvest in Massachusetts, USA...

Congenital melanocytic nevi can be stigmatising for the patient. Larger nevi bear an increased risk for melanoma development. Large congenital melanocytic nevi may be a symptom of neurocutaneous melanosis. We report on a 5-year-old boy with an extensive hair-bearing facial congenital melanocytic nevus, covering forehead, glabella and temple region associated with unilateral brow and blepharoptosis. The lesion was excised en bloc. The resulting defect had been closed by full thickness skin graft. Healing was unremarkable and long-term follow-up over 13 years demonstrated a satisfying esthetic and functional outcome...
