Contactin-associated protein-like 2 (CNTNAP2 or CASPR2) is a neuronal transmembrane protein of the neurexin superfamily which is correlated with pain related hypersensitivity. Recent results indicated that the hyperactive phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway may be a promising therapeutic target for pain-related hypersensitivity in patients with dysfunction of CNTNAP2. Resveratrol is one of the most widely studied polyphenols with several beneficial properties. In the present study, we investigated the effects of resveratrol on the pain related hypersensitivity. And we found that the up-regulated phosphorylation of S6 could be suppressed by resveratrol. The nocifensive behavior duration time to heat and chemical algogens stimulation in Cntnap2-deficiency (Cntnap2) mice could be attenuated by resveratrol. Our results indicated that resveratrol could rescue the pain related hypersensitivity for Cntnap2 mice may be via mTOR signaling pathway.

First Bite Syndrome: A Rare Post-Surgical Complication Following a Carotid Body Tumor Excision.
Cureus
January 2025
Clinical Pharmacy and Neurology, King Saud Medical City, Riyadh, SAU.
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.

Background: An updated systematic review of cervical musculoskeletal dysfunction in migraine and tension-type headache is needed. Influencing factors (pain hypersensitivity with cervical musculoskeletal testing, active trigger points and tenderness) have not been investigated.
Objectives: To i) update evidence for cervical musculoskeletal impairments in migraine and tension-type headache ii) report on accompanying pain associated with testing, active trigger points and tenderness in headache; iii) determine relationships between these sensitivity features and cervical musculoskeletal impairments in headache.

Sleep is crucial for sustaining normal physiological functions, and sleep deprivation has been associated with increased pain sensitivity. The histone deacetylases (HDACs) are known to significantly regulate in regulating neuropathic pain, but their involvement in nociceptive hypersensitivity during sleep deprivation is still not fully understood. Utilizing a modified multi-platform water environment technique to establish a sleep deprivation model.

Brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrkB) are known to contribute to both protective and pronociceptive processes. However, their contribution to neuropathic pain after spinal cord injury (SCI) needs further investigation. In a recent study utilizing TrkB mice, it was shown that systemic pharmacogenetic inhibition of TrkB signaling with 1NM-PP1 (1NMP) immediately after SCI delayed the onset of pain hypersensitivity, implicating maladaptive TrkB signaling in pain after SCI.

Article Synopsis
- Hereditary Angioedema (HAE) is a rare autosomal dominant disorder characterized by low levels or dysfunctional C1 inhibitor, leading to recurrent episodes of swelling and abdominal pain.
- A reported case involves a 53-year-old man with a longstanding history of recurrent edema and family history, who showed low levels of plasma proteins but faced treatment challenges despite various therapies, including a trial of Lanadelumab for prophylaxis.
- The patient's experience highlights issues in managing HAE, revealing an adverse reaction to Lanadelumab that is not commonly documented, emphasizing the need for better-informed treatment strategies.
