First bite syndrome (FBS) is characterized by intense pain in the parotid area that starts with the first bite of food spontaneously. FBS is an uncommonly observed surgical complication of head and neck surgery. A 36-year-old male patient reported extreme pain after surgical excision of a carotid body tumor (CBT) in the ipsilateral parotid gland region at the first bite of each food intake, which improves gradually with continued mastication. Several factors are believed to be responsible for this phenomenon, including injury or amputation of the cervical sympathetic trunk. Loss of sympathetic innervation makes the parotid gland hypersensitive to parasympathetic stimulation. The best treatment for FBS is not yet firmly established, even though symptoms tend to improve with time in some cases. We report this case of FBS after CBT excision to raise awareness among maxillofacial surgeons of this surgical complication.

First-bite syndrome (FBS) is manifested as acute and severe pain in the parotid region occurring at the first bite of a meal. While most cases of FBS arise after surgeries involving the deep lobe of the parotid gland, chemotherapy-induced FBS is extremely rare. Some adverse effects of oxaliplatin resemble FBS, suggesting it may be under-recognized.

Background: Rupture of the lumbar catheter in lumboperitoneal (LP) shunts is rare and typically occurs due to long-term mechanical stress. The authors describe an unusual case of early postoperative lumbar catheter severing after a fall on the buttocks.
Observations: A 78-year-old woman underwent LP shunt placement for communicating hydrocephalus after aneurysmal subarachnoid hemorrhage.

Rationale: The occurrence of delayed Horner's syndrome caused by a dog bite to the neck is rarely reported. Acute stress disorder (ASD) can easily be neglected when diagnosing this disease in trauma patients who cannot be effectively observed. The symptoms of Horner's syndrome may not be readily detected in patients with ASD.
