©2018 by Anais Brasileiros de Dermatologia Dear Editor, Onychomatricoma (OM) is a rare benign neoplasm of nail matrix origin. The disease was first described by Baran and Kint in 1992 in a report of three cases.1 In some cases, it may present itself with important nail dystrophy, which makes its diagnosis a challenge. We report a rare case of OM in which we discussed the clinical and dermoscopi...

Median canaliform nail dystrophy is an unusual condition of the nail, most often affecting the thumb (1). It is characterized by a longitudinal split or canal in the nail with small transversal fissures, in a fir-tree configuration. The condition is diagnosed based on its clinical features (2, 3). While the underlying mechanism is unknown, it has been suggested that median canaliform nail dystr...

and knee motion for positioning. Flex the hip to almost 90°. Remove the proximal and distal locking screws in standard fashion. Lay a guidewire on the thigh and obtain a fluoroscopic image of the proximal hip. Adjust the wire to coincide with the femoral nail on the lateral view. Draw a line along the wire, extending it onto the buttock. Externally rotate the thigh and mark a line in a similar ...

BACKGROUND In the phase III double-blind Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis (ESTEEM) 1 and 2, apremilast, an oral phosphodiesterase 4 inhibitor, demonstrated efficacy in moderate to severe psoriasis. OBJECTIVE We sought to evaluate efficacy of apremilast in nail/scalp psoriasis in ESTEEM 1 and 2. METHODS A total of 1255 patients were randomized (2:1)...

UNLABELLED Fractures of the femoral shaft treated with interlocking nails will ultimately result in breakage of the nail if the bone does not unite. Further management requires removal of the broken nail which may be a difficult process for the distal segment. If we can identify the symptoms just before the nail breaks, an exchange nailing becomes much easier. We present a patient with fibromat...

Ingrowing toenails are a common condition that causes pain and disability in the foot. The condition occurs when the nail plate traumatises the nail fold, giving rise to pain, inflammation, or infection (or a combination thereof). It commonly occurs in the great toe but can also affect the lesser toes. Patients with ingrowing toenails are usually male, between the ages of 15 and 40 years; they ...

BACKGROUND Penetrating nail-gun injuries to the head are rare, however, the incidence has been gradually rising over the last decade. While there is a large volume of case reports in the literature, there are only a few incidences of cerebrovascular injury. We present a case of a patient with a nail-gun injury to the brain, which compromised the cerebral vasculature. In this article, we present...

We describe a rare case with breakage of gamma nail accompanied by nonunion of the original fracture and a subsequent new fracture in the ipsilateral femur. A 73-year-old woman suffered a subtrochanteric fracture of the femur, and the fracture was fixed with gamma nail at a previous hospital. However, fracture reduction was not adequately achieved and a large gap remained between the fracture f...

This article reviews studies of Fixion expandable nail biomechanical properties in case of long bones fractures osteosynthesis. The purpose of this study was to systematize biomechanical researches dedicated to the expandable nail. There were found seven biomechanical studies published between 2005 and 2008. Among them, six studies are devoted to mechanical experiments, and one is a comment to ...

Onychophagia is defined as chronic nail biting behaviour, which usually starts during childhood. Onychotillomania results from recurrent picking and manicuring of the fingernails and/or toenails, leading to visual shortening and/or estraction of nails. The aim of this study was to assess the prevalence of onychophagia and onychotillomania in young adults, and the comorbidity of these conditions...
