BACKGROUND: To report the presentation, diagnostic process, management and results of cochlear implantation of patients diagnosed with Bjornstad syndrome with profound sensorineural hearing loss (SNHL).
UNASSIGNED: A retrospective report of two siblings with Bjornstad syndrome suffering profound SNHL unresponsive to conventional hearing aids treated with bilateral simultaneous cochlear implantation.
METHODS: Tertiary-referral center.
RESULTS: Cochlear implant surgeries of two siblings (four ears) with profound SNHL and bilateral inner ear anomaly (incomplete partition type 1) were performed without complications. Postoperative audiometric measurements showed a significiant improvement in pure-tone threshold and a word recognition score. In the literature review, no previous case of Bjornstad syndrome treated with cochlear implantation has been reported.
CONCLUSIONS: Cochlear implantation is an effective, safe, and ultimate treatment option for Bjornstad syndrome with profound SNHL not responding to hearing aids.

Pili torti or \'twisted hair\' is characterized by flattened hair shaft twisted through 180 degree around their long axis at irregular intervals. It is inherited or acquired hair shaft disorder with increased fragility. It may be associated with numerous dermatological and systemic conditions or may be drug-induced. An isolated pili torti case is reported which is very rare and the related literature reviewed.

Although the clinical hair changes that occur under treatment with epidermal growth factor receptor inhibitors (EGFRIs) are documented, their trichoscopic features have not been reported.
To evaluate the trichoscopic findings in scalp and facial hair, induced by EGFRI treatment.
Patients treated with EGFRIs at a tertiary oncodermatology clinic in 2015 through 2017 were evaluated for macroscopic and trichoscopic changes.
The cohort included 23 patients (13 women; median age, 68 years) treated with EGFRIs for an average of 13 months (range, 2-40 months). Macroscopically, 18 patients (78%) had dry, lusterless, coarse, kinky, brittle scalp hair, and 17 (74%) had trichomegaly of the eyebrows/eyelashes. Trichoscopic findings were of hair shaft anomalies including pili torti, affecting scalp hair in 20 patients (87%), eyebrows in 6 (26%), and eyelashes in 8 (50%), and asymmetric hyperpigmented fusiform widening of hair scalp in 3 (13%), eyebrows in 10 (43%), and eyelashes in 4 (25%). Dermoscopic findings of the peri- and interfollicular skin were scale, whitish erythematous structureless areas, and branching vessels.
Lack of trichoscopic-histologic correlation, lack of baseline examination.
The trichoscopic correlates of the macroscopic hair changes under EFGRI treatment include pili torti, and asymmetric hyperpigmented fusiform widening, with dermoscopic cutaneous manifestations of scale, whitish erythematous structureless areas, and branching vessels.
