Objective: To investigate the efficacy of percutaneous balloon compression of the Gasserian Ganglion (PCGG) in the treatment of trigeminal neuralgia(TN)and the influencing factors of recurrence after PCGG.
Methods: The clinical data of 221 patients with TN treated by PCGG were retrospectively analyzed and followed-up to explore the postoperative efficacy.
Results: There were 158 cases of immediate disappearance of pain and 59 cases of delayed pain disappearance in patients after one PCGG operation, for an overall efficacy rate of 98.2%. Forty-nine patients experienced recurrence of pain, for a recurrence rate of 22.6%, and average recurrence time of 18 months. The effective rate of medication in patients with recurrent trigeminal neuralgia is 85.7%.Univariate and multivariate logistic regression analyses showed that hypertension disease and delayed pain disappearance were independent factors for recurrence. The incidence of inhibitory reaction of the trigeminal nerve during the operation was 97.3%. The most common postoperative complications were facial numbness, masticatory-muscle weakness, tinnitus, diplopia and keratitis, which occurred at rates of 76.9%, 28.1%, 14.5%, 11.8% and 10.4%, respectively. All of the complications resolved within 3 years after PCGG.
Conclusions: PCGG is a safe and effective surgical method for the treatment of TN. The pain in most patients disappeared after surgery, leaving sequelae such as facial numbness, masticatory-muscle weakness and tinnitus. The mean time to recurrence of postoperative pain was 18 months, with hypertension disease and delayed pain disappearance as associated factors.

Background: Delayed onset muscle soreness (DOMS) is a well-established phenomenon characterized by ultrastructural muscle damage that typically develops following unfamiliar or high-intensity exercise. DOMS manifests with a constellation of symptoms, including muscle tenderness, stiffness, edema, mechanical hyperalgesia, and a reduced range of joint motion. In recent years, the application of blood flow restriction (BFR) has garnered attention for its potential impact on DOMS.

Prompt emergence from general anesthesia is crucial after neurosurgical procedures, such as craniotomies, to facilitate timely neurological evaluation for identification of intraoperative complications. Delayed emergence can be caused by residual anesthetics, metabolic imbalances, and intracranial pathology, for which an eye examination can provide early diagnostic clues. The sunset sign (or setting sun sign), characterized by a downward deviation of the eyes, can be an early indicator of raised intracranial pressure (ICP) or midbrain compression, as is commonly observed in states of hydrocephalus or periaqueductal or tectal plate dysfunction.

Plantar psoriasis is a chronic inflammatory skin disorder, typically characterized by erythematous plaques with thick silvery scales localized on the soles. This condition can significantly impair patients' quality of life, particularly through pain and mobility challenges. It is considered a subtype of plaque psoriasis but presents unique diagnostic and therapeutic challenges due to its specific location.

Acute intermittent porphyria (AIP) is a rare inherited metabolic disorder caused by decreased activity of the enzyme porphobilinogen deaminase in the heme synthesis pathway. This leads to the accumulation of toxic porphyrin precursors, such as porphobilinogen and δ-aminolevulinic acid. Clinical manifestations typically include episodic bouts of severe neurovisceral pain and autonomic dysfunction.
