Case ReportsRight Aortic Arch With Kommerell Diverticulum: A Rare Cause of Dysphagia.
Dysphagia is a common condition with multiple causes. Fortunately, a thorough evaluation will often lead to a correct diagnosis, even when the cause is a rare entity. A right aortic arch with associated aberrant left subclavian artery is an uncommon anatomical variant. Physicians involved in the management of dysphagia should be aware of vascular anomalies that can cause dysphagia. ⋯ Kommerell diverticulum, a remnant of the left dorsal arch, is a rare cause of dysphagia. However, vascular causes should be considered in the algorithm when evaluating patients who present with dysphagia, especially when there is compression of the esophagus noted on imaging or examination.

Case ReportsA Case of Trigeminocardiac Reflex During Infrastructure Maxillectomy.
The trigeminocardiac reflex refers to the sudden development of bradycardia or even asystole with arterial hypotension from manipulation of any sensory branches of the trigeminal nerve. Although it has only rarely been associated with morbidity and tends to be self-limited with removal of the stimulus, it is an important phenomenon for head and neck surgeons to recognize and respond to. ⋯ The trigeminocardiac reflex can be provoked by a number of head and neck and skull base procedures including parotidectomy and posterior maxillectomy. Surgeons and anesthesiologists should be wary of inciting the reflex during manipulation of trigeminal branches. Careful dissection for prevention and early intervention with stimulus removal and anticholinergic use as needed are paramount to ensure good outcomes.

Review Case ReportsA duplication of the mouth associated with a dysontogenic cyst: a case report and discussion of theories of origin.
IMPORTANCE Diprosopus is a medical condition that refers to full or partial craniofacial duplication. A particular subset of this condition, duplication of the mouth, is an exceedingly rare condition, with 7 reported cases in the medical literature. The embryogenesis and mechanism of disease are not well understood. ⋯ CONCLUSIONS AND RELEVANCE On the basis of our findings, we propose the mechanism of origin for duplication of the mouth to be duplication of the first branchial arch. This case offers a deeper understanding of the mechanism of this disease than previously reported. Additional basic science and clinical research is needed to corroborate this theory.

What parents say about their child's surgeon: parent-reported experiences with pediatric surgical physicians.
Reviews of patient and caregiver experience with health practitioners are increasingly important to consumers. Understanding physician qualities valued by patients and their families may facilitate more effective care and communication. ⋯ Parents highly value physician interpersonal style and visit-specific skills (involving the child in discussion; showing empathy/concern for the patient/family; answering questions; explaining treatment). While most comments about surgeons were affirmative, clinical systems were more often negatively perceived. Attention to parent-reported experiences may help physicians improve communication and overall effectiveness of care provided.

Case ReportsImplications of carotid sinus hypersensitivity following preoperative embolization of a carotid body tumor. An indication for prophylactic intraoperative cardiac pacing.
IMPORTANCE Carotid body tumors are rare neoplasms of neural crest origin that are both highly vascularized and locally invasive. Treatment options for these tumors often include surgery with preoperative embolization, which can pose major cardiovascular risk to patients. As demonstrated by this case report, hemodynamic instability following preoperative embolization of a carotid body tumor may indicate severe carotid sinus hypersensitivity and the need for temporary cardiac pacing. ⋯ Following a negative cardiac workup, a temporary pacemaker was implanted, and surgical resection of the tumor was successfully completed. CONCLUSIONS AND RELEVANCE Carotid sinus hypersensitivity is a rare but serious risk of preoperative embolization of carotid body tumors. Postembolization bradycardia or hypotension should be assessed as potential harbingers of carotid sinus hypersensitivity, and the need for temporary intraoperative cardiac pacing should be strongly considered.
