Complex regional pain syndrome (CRPS) is a neuropathic pain disorder, characterized by persistent and severe pain after trauma or surgery. Diagnosis is mainly based on clinical signs and treatment is based on a multidisciplinary approaches, including non-pharmacological approaches and occupational therapy，pharmacotherapy and invasive therapeutics. This article reviewed the current advice of diagnosis and treatment of CRPS.

Recently studies have shown that ketamine given to patients under mechanical ventilation and background anesthetics without adversely altering cerebral hemodynamics. More studies have also shown ketamine has neuroprotective effects. The main mechanisms may involve changing the expression of apoptosis-regulating proteins, inhibiting the toxicibility of excitatory amino acid and decreasing Ca2+ influx by blockade of NMDA receptors activation. It can also inhibit proinflammatory cytokine production induced by tissue ischemia and affect the protein kinase phosphorylations related to cerebral ischemia, etc..

BACKGROUND:Ultrasonic therapy is one of several physical therapy modalities suggested for the management of pain and loss of function due to osteoarthritis. However, its effectiveness stil remains controversial in the previous studies.
OBJECTIVE:To analyze the effect of ultrasonic therapy for the treatment of relieving knee osteoarthritis pain.
METHODS:A retrieval of Pubmed, Ovid/Medline, Ovid/EMBASE, and Cochranee database was performed. The relevant literatures were manual y retrieved. The retrieval deadline was set on March 31, 2014. Randomized control ed trials on ultrasonic therapy of knee osteoarthritis were col ected.
RESULTS AND CONCLUSION:A total of eight studies of meta-analysis were accumulated. Among them, six studies adopted visual analog scale and Western Ontario and McMaster Universities Arthritis Index, one study adopted visual analog scale only, and one study adopted Western Ontario and McMaster Universities Arthritis Index. Then the Western Ontario and McMaster Universities Arthritis Index scores were transformed into visual analog scale scores for data analysis. There was a statistical difference between the groups in the visual analog scale pain score (standardized standard deviation:-0.51;95%confidence interval:-0.68,-0.33;P=0.05). Ultrasonic therapy is an effective method for knee osteoarthritis pain.

14 aged patients received radiofrequency current ablation(RFCA)to treat drug-refractory tachycardia. The success rate was 97%(13/14).In conjunction with the charcteristicaof aged patients often with long clinical history and apt to be complicated,the paper especially discussed the distinctive feature of application of RFCA to aged patients.

Objective:To investigate the ocular clinical manifestations in pediatric patients with incontinentia pigmenti (IP).Methods:A case series study was carried out and a retrospective analysis was performed.Clinical data of 13 pediatric patients with IP treated from January 2013 to December 2019 in Xijing Hospital were collected.All the patients underwent regular ophthalmologic examination.Three patients accepted fundus fluorescein angiography and six eyes of five patients were treated with retinal photocoagulation or anti-vascular endothelial growth factor (VEGF) intravitreal injection according to severity of the condition.The follow-up period ranged from 6 months to 6 years.The medical history, family history, systemic manifestations, ocular characteristics, diagnosis, treatment as well as ocular and systemic changes during follow-up were recorded and analyzed.This study followed the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Xijing Hospital, Fourth Military Medical University (No.KY20203287-1).Results:All the 13 patients were female aged from 5 days to 42 months at first visit, with the average age of 2.0 (1.0, 8.5) months.As for the main skin lesions at first visit, there were 4 cases in erythematous vesicle stage, 3 cases in verrucous exanthema stage, and 6 cases in hyperpigmented stage.There were 7 cases in shrinkage stage during follow-up.Among the 26 eyes of 13 patients, 18 eyes of 10 patients showed ocular anomalies, accounting for 76.9% of total patients (69.2% of total eyes). Among the 13 patients, 8 patients presented bilateral ocular involvement, 2 patients showed unilateral anomalies, and 3 patients had no ocular lesions.The retina was involved in all patients with ocular manifestations.The typical retinal lesions included avascular zone of peripheral retina in 13 eyes, tortuous and dilated retinal vessels in 10 eyes, increased vascular branch in 7 eyes, white linear retinal arteries and partial vascular occlusion in 4 eyes, retinal neovascularization in 3 eyes, total retinal detachment in 2 eyes, and retinal fold with macular lamellar hole in 1 eye.In addition, there was retinal hemorrhage in 11 eyes, retinal pigment changes in 4 eyes, grey ridge lesions in 3 eyes, macular dysplasia in 2 eyes, choroidal atrophy in 1 eye, optic gliosis in 1 eye and yellowish-white retinal exudate in 1 eye.There were also 4 patients with other ocular manifestations, such as strabismus and eyeball atrophy.Retinal photocoagulation was performed in 4 eyes of 3 patients and anti-VEGF intravitreal injection in 2 eyes of 2 patients.The retinal lesions regressed and the condition of patients kept stable during follow-up.Conclusions:The ocular clinical manifestations in patients with IP are usually typical and diverse, and the retinal vascular lesion is the main type.Early diagnosis and timely treatment are of great significance.

Objective:To investigate the fundus fluorescein angiography (FFA) characteristics of spontaneous regression in retinopathy of prematurity (ROP) and the range of retinal vascularization.Methods:A clinical retrospective study. A total of 82 eyes of 41 infants with ROP, who underwent FFA from January 2019 to December 2021 in Department of Ophthalmology of Xijing Hospital after completion of ROP regression, were included. There were 25 males (50 eyes) and 16 females (32 eyes). ROP was diagnosed in Zone Ⅱ in 44 eyes, with 38 eyes in stage 2 and 6 eyes in stage 3, and in zone Ⅲ in 38 eyes of stage 2. All patients underwent FFA examination under general anesthesia, at postmenstrual age of 70.70±12.25 weeks, after the natural regression of ROP was completed. Focus on the retinal vascular development, as well as choroid circulation and macular abnormalities, and compare and observe the differences between zone Ⅱ and Ⅲ after spontaneous regression. The extent of retinal vascularization was determined by the ratio between the distance of the center of the disc to the border of the vascularized zone (DB) and the center of the disc to the fovea distance (DF). The width of avascular area, recorded as the distance from the ora serrata to the vascular termination, was counted by disc diameters (DD). The measurement data between zone Ⅱ and zone Ⅲ ROP were compared by the independent sample t-test, and the count data were compared by χ2 test or Fisher exact probability test. Results:The linear choroidal pattern was present in 9 eyes (21.95%, 9/41), and the tortuous arteries in the posterior retina were detected in 32 eyes (39.02%, 32/82). It was noted that increased branching of vessels presented in 45 eyes (54.88%, 45/82), straight shape of vessels shown in 27 eyes (32.93%, 27/82), circumferential vessels arisen in 45 eyes (54.88%, 45/82), arteriovenous shunt appeared in 18 eyes (21.95%, 18/82), and capillary bed lost in 46 eyes (56.10%, 46/82) in areas from initial ridge to vascular termini. Punctate or linear dye leakage was observed in 23 eyes (28.05%, 23/82) during the late phase of FFA. Macular abnormalities, such as the absence of foveal avascular zone and hypoperfusion, were observed in 28 eyes (34.15%, 28/82), of which the macular ectopia presented in 1 eye. The mean DB/DF ratio of all the 82 eyes on the temporal side was 4.63±0.29 and 3.77±0.23 in the nasal. The mean avascular area on the temporal retina was 1.74±1.00 DD. Compared with ROP in zone Ⅲ, increased branching of vessels and dye leakage were more common ( χ2=9.303, 10.774; P=0.002, 0.001), the extent of temporal retinal vascularization was smaller ( t=-2.285, P=0.026), and the avascular area of the retina was more significant ( t=5.491, P<0.001) in zone Ⅱ ROP. Conclusions:Even after completion of spontaneous regression in ROP, incomplete retinal vascularization and vascular abnormalities may exist permanently in FFA, including those such as the tortuous arteries in the posterior retina, increased branching and straight shape of vessels, circumferential vessels, capillary bed lost and macular abnormality. Further appropriate follow-up is needed for long-term safety.
