AIM: To describe prevalence and different clinical signs and management of cases with penetrating eye injuries during loco-regional anesthesia for ophthalmic surgery. METHODS: A retrospective review of clinical records was carried out, identifying cases of globe penetration secondary to peribulbar anesthesia injection during 5 y activity in Centro de Oftalmología Barraquer. RESULTS: A total of 17 460 needle-based ocular anesthesia procedures were performed in our centre and 4 cases of globe penetration were recorded with an estimated prevalence of 0.024%. Globe penetrations were always detected in the first 24 h after surgery. Vitreous haemorrhage was found in all the cases. Two eyes presented retinal detachment and two eyes choroidal detachment(CD). The initial surgical approach was performed within the first 48 h. Silicone oil was used as tamponade in three eyes and the fourth case remained only with air. Detachments were solved successfully in all the cases. Functional results varied among cases, depending on ocular remarkable antecedent and globe penetration with or without retinal or ***: Prevalence of globe penetration during loco-regional anesthesia is low in our centre. Physicians should consider the possibility of globe penetration in eyes with postoperative atypical appearance after locoregional anesthesia. Immediate B-scan ultrasonography is recommended in suspicious cases with a dense vitreous haemorrhage. An early vitrectomy surgery in conjunction with laser or cryotherapy at the penetration sites is essential for good anatomical and functional results.

Extra-anatomic aortic bypass for the treatment of a mycotic pseudoaneurysm after liver transplantation for hilar cholangiocarcinoma

引用

Hepatobiliary & Pancreatic Diseases International 2021年第3期20卷 285-287页

Liver transplantation(LT) after neoadjuvant chemoradiotherapy in patients with unresectable hilar cholangiocarcinoma(HC) is an accepted treatment strategy [1]. Neoadjuvant therapy is associated with an increased risk of arterial and portal complications after LT [1,2]. In most cases, radiation therapy makes the use of the native hepatic artery inadvisable, and an aortic anastomosis is needed, either with or without a graft [2].

Oxidative stress in brickmakers of Juárez City, Chihuahua, México: Case-control study

Advances in Bioscience and Biotechnology 2012年第7期3卷 1051-1059页

A case-control study was conducted in a brickmaker’s community in Juarez City, Chihuahua in Mexico. This population has been chronically exposed to a wide spectrum of potentially health-damaging pollutants that include coarse, fine and ultrafine particles, carbon monoxide (CO), oxides of nitrogen and sulphur, transitional metals, polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds and bioaerosols. Lipid peroxidation level (LPX) and protein carbonyl content (PCC) help to evaluate oxidized protein content and activity of the antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) were evaluated in blood samples of study participants. The group of occupationally exposed (OE) workers consisted of 30 individuals ranging in age from 25 to 55 years, with a mean of 15 years in a brick production-related job. The control group included 30 volunteers who were neither environmentally nor occupationally exposed to brick production activities and whose sociodemo-graphic characteristics were similar to the OE group. Results indicate that none of workers used any type of protective equipment (respirator or face mask, gloves, coveralls) during brick manufacturing. LPX and PCC significantly increased (p < 0.5) in the OE group compared to the control group. SOD, CAT and GPx activity was significantly increased (p < 0.5) in the OE group compared to the control group. Therefore, evaluation of stress oxidative biomarkers is advisable in order to assay chronic exposure to workers in brick manufacturing.

Extracellular matrix components in peripheral nerve repair:how to affect neural cellular response and nerve regeneration?

Neural Regeneration Research 2014年第22期9卷 1943-1948页

peripheral nerve injury is a serious problem affecting signiifcantly patients’ life. Autografts are the“gold standard” used to repair the injury gap, however, only 50% of patients fully recover from the trauma. Artiifcial conduits are a valid alternative to repairing peripheral nerve. They aim at conifning the nerve environment throughout the regeneration process, and providing guidance to axon outgrowth. Biocompatible materials have been carefully designed to reduce inlfamma-tion and scar tissue formation, but modiifcations of the inner lumen are still required in order to optimise the scaffolds. Biomicking the native neural tissue with extracellular matrix ifllers or coatings showed great promises in repairing longer gaps and extending cell survival. In addition, extracellular matrix molecules provide a platform to further bind growth factors that can be released in the system over time. Alternatively, conduit ifllers can be used for cell transplantation at the injury site, reducing the lag time required for endogenous Schwann cells to proliferate and take part in the regeneration process. This review provides an overview on the importance of ex-tracellular matrix molecules in peripheral nerve repair.
