Consensus Statement on the Use of Botulinum Neurotoxin in the Middle East.

Background: Aesthetic minimally invasive procedures have become very popular and culturally acceptable among Middle Eastern populations. Botulinum neurotoxin type A (BoNTA) is a valuable treatment modality for many cosmetic as well as therapeutic indications. The presence of BoNTA in our toolkit has revolutionized the field of aesthetic medicine to the point where it is now one of the most commonly performed cosmetic procedures worldwide.

Acne exacerbation after tofacitinib treatment for alopecia areata.

The major discovery of the novel therapeutic Janus kinase (JAK) inhibitors has been implicated in several dermatological diseases. Recently, studies have shown the efficacy and encouraging results of oral JAK inhibitors as a treatment for alopecia areata (AA). Due to the novelty of this treatment, potential side effects are not fully explored.

Delayed hypersensitivity reaction to hyaluronic acid dermal filler following influenza-like illness.

Delayed reactions after facial hyaluronic acid injection are relatively rare complications. Their cause may be infectious or immune-mediated in origin, and their outbreak can be triggered, for example, by an influenza-like illness. To describe potential adverse event of influenza like illness following dermal filler injection.

Steatocystoma Multiplex Suppurativa: A Case with Unusual Giant Cysts over the Scalp and Neck.

Steatocystoma multiplex (SM) is a rare hamartomatous malformation of the pilosebaceous duct junction. Most cases of SM are sporadic, although less common autosomal dominant inherited forms have been reported. Steatocystoma multiplex suppurativa (SMS) is a much rarer inflammatory variant of SM, associated with severe inflammatory lesions resembling those of hidradenitis suppurativa.

New Classification System for Tear Trough Deformity.

Background: Tear trough deformities (TTD) refer to a set of conditions leading to different shapes in the junction between the lower eyelid and the cheek. Tear trough deformity is a major aesthetic concern for a lot of individuals seeking periorbital rejuvenation and is one of the most discussed landmarks in facial aesthetic surgery.

Objective: To describe a new morphologically related classification system, providing an objective means to evaluating the deformity.

Lateral oblique forehead lines: redefining sleeping lines and treatment with botulinum toxin A.

Background: Lateral oblique forehead lines had previously been defined as "sleeping lines." We present arguments to support the premise that these lines are not caused by sleeping position, but arise instead from the repeated contraction of powerful frontalis and orbicularis oculi muscles and can therefore be successful treated with onabotulinum toxin A.

Objectives: To understand the causes behind the development of lateral oblique forehead lines and to look at treatment outcomes using onabotulinum toxin A.
