Primary lingual dystonia is a rare condition, especially when it is only induced by speaking. Trihexyphenidyl failed to improve the symptoms. Several case series have demonstrated the effectiveness of botulinum toxin injection for the management of focal lingual movement disorders. Only 1 case of botulinum toxin injection for primary lingual dystonia induced by speaking has been reported, but this treatment has limited effectiveness. Our patient was treated with botulinum toxin using a superficial approach for injection into the tongue with continuing excellent results. Lingual botulinum toxin injection is a fairly simple, safe and viable treatment option for lingual dystonia induced by speaking.

Partial fascicular oculomotor palsy, the combination of bilateral midriasis with loss of vertical gaze movements, is rarely a consequence of midbrain infarction. We describe a patient with acute ischemic infarcts involving both upper most part of the midbrain, presenting with marked vertical gaze palsy and mydriasis bilaterally as the only neurological abnormality. These features are suggestive of partial fascicular oculomotor palsies involving the pupil, inferior rectus(IR), superior rectus(SR), inferior oblique(IO) muscles and sparing medial rectus(ML), levator palpebrae(LP) muscles. These neuro-ophthalmological and radiological findings in our case support the model that the fibers to medial rectus and levator palpebrae muscles might be located in the more caudal portion of the oculomotor fascicles.

BACKGROUND: Selective lung intubation is a life-saving procedure in emergency departments. While various equipment can be used in selective lung intubation, most of this equipment is not readily available; therefore, single-lumen endotracheal intubations are performed for rapid interventions. MATERIALS AND METHODS: This study was designed as a randomized, prospective, cross-over study using the 90° rotation technique for selective intubation on a manikin model with and without endotracheal tube introducer (ETI) in difficult airway settings. Forty-six emergency physicians were included in the study. The primary outcome was evaluating time to selective intubations, and secondary outcomes were first and second attempt success rates and the self-perceived difficulty level of each method according to the participants. RESULTS: The mean time to the first successful endotracheal intubation was significantly longer for both right selective and left selective intubations with ETI utilization than without ([39.71 ± 9.83 vs. 21.86 ± 5.94 s], [P < 0.001]), ([42.2 ± 10.81 vs. 26.23 ± 7.97 s], [P < 0.001], respectively). The first-pass success rate did not differ for right selective intubation with or without an ETI (45/46 [97.8%] and 45/46 [97.8%], respectively). However, the first-pass success rate for left selective intubation was significantly higher with ETI as compared to without an ETI (30/46 [65.2%] and 13/46 [28.3%], respectively) (P < 0.001). CONCLUSIONS: While the success rates of right selective intubation were the same, the left selective intubation success rates with ETI are higher than the styletted endotracheal tube, which can be strong evidence for this method's applicability in practice. Expanding the use of ETI and increasing the experience of the practitioners can contribute to further success.
