Introduction: Adhesive tape is commonly used to secure endotracheal tubes (ETT) during general anaesthesia. Although a variety of adhesives are used in practice, few studies have investigated the likelihood of different adhesives in producing facial skin injury. Given that differences in cost exist between adhesives that are often used interchangeably, it would be prudent to use the most economical option.

Klippel-Trenaunay syndrome (KTS) is a rare, clinically variable congenital disorder involving capillary malformations, soft tissue or bone hypertrophy, and venous malformations or varicose veins. We report a 28-year-old man who presented with a hypertrophic right arm as well as markedly increased ipsilateral axillary hyperhidrosis and erythematous patches on the back, chest, and arm. This case of KTS is unusual because our patient presented with a markedly increased unilateral axillary hyperhidrosis ipsilateral to the hypertrophic limb.

Objective: Anti-tumor necrosis factor medications have demonstrated good efficacy in treating psoriatic arthritis (PsA). Clinical responses at the primary end point in recent clinical trials of golimumab in PsA subjects yielded lower American College of Rheumatology 20% criteria for improvement (ACR20) responses than those seen in the Infliximab Multinational Psoriatic Arthritis Controlled Trial 2 infliximab study. However, baseline C-reactive protein (CRP) levels of PsA subjects enrolled in these trials differed significantly.

Psoriasis is a chronic immune-mediated inflammatory disease of unknown etiology. Unlike other chronic inflammatory diseases receiving continuous treatment, psoriasis has traditionally been treated intermittently secondary to concern for cumulative toxicity of conventional systemic therapies. However, the development of targeted anti-inflammatory biologic agents allowed for continuous therapy for most patients.

Adults with psoriasis have a greater risk of developing metabolic syndrome (MetS) and cardiovascular disease (CVD), but few studies have investigated the prevalence of MetS and other risk factors for CVD in children with psoriasis. In an assessor-blinded study, 20 children ages 9-17 years with a current or previously documented history of psoriasis involving 5% or more of their body surface area or psoriatic arthritis were compared with a cohort of age- and sex-matched controls with benign nevi, warts, or acne. MetS, our primary endpoint, was defined by the presence of abnormal values in at least three of the following measures: triglycerides, high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), waist circumference, and blood pressure.

Article Synopsis
  • The study investigates the effectiveness of biologic treatments for psoriasis compared to conventional therapies and phototherapy in clinical practice settings, finding that biologics tend to perform better overall.
  • A retrospective analysis of patient visits from 2008 to 2012 was conducted, focusing on various treatment outcomes and using specific evaluation metrics, while excluding certain patients with insufficient baseline data.
  • Results showed a significant difference in improvement, with biologics achieving a 70.2% reduction in disease activity (measured by S-MAPA) at 24 weeks, compared to a 40.4% improvement for conventional treatments, suggesting biologics may be a more effective option.
