A case of thunderstorm phobia in a Maremma sheepdog
No full textA 5-year-old neutered female Maremma sheepdog, probably crossed with a Retriever, was examined due to a severe phobia of thunderstorms and loud noises. Adopted in late summer, she immediately presented signs of thunderstorm phobia and nocturnal awakenings. For this reason, the owners immediately turned to a veterinary behaviorist, who recommended behavior modification training based on creating a safe zone, desensitization and counter-conditioning with general thunderstorm sound effects. The therapy seemed to have immediately an effective outcome immediately, thanks to the start of autumn and decreasing thunderstorms, however due to the return of spring the dog started to show the same symptoms again. During the second visit, performed by the author, videos of nocturnal awakenings and panic reactions associated with thunderstorms were evaluated. The diagnosis was of phobia of thunderstorms and loud noises, characterized by sporadic panic attacks. Behavioral modification therapy was continued and Adaptil Collar® was introduced and Alprazolam as needed was prescribed. After the first summer, the owners agreed to administer Clomipramine on an ongoing basis to prepare the dog for the next summer. In the presence of medium-intensity thunderstorms, behavioral manifestations were reduced to trembling only and symptoms of anxiety in response to a change in barometric pressure had almost disappeared. Finally, thanks to the results obtained and to meet the requests of the owners, the following year will be managed by stopping the therapy with Clomipramine and keeping the Alprazolam as needed

Transparency for Authoritarian Stability: Open Government Information and Contention with Institutions in China
No full textConventional wisdom holds that authoritarian states bear a cost to social stability for disclosing information. This study investigates the effect of an increasingly common transparency initiative in authoritarian countries: open government information (ogi). By publishing policy information, ogi allows citizens to identify illegal government behavior. Drawing from the Chinese case, the author theorizes that although such policy transparency reveals whether governments violate laws, it encourages the use of institutional channels for resolving disputes. By redirecting popular discontent from the streets to institutions, such transparency initiatives foster social stability in autocracies rather than threatening it. Using online and in-the-field survey experiments about ogi on land-taking compensation, the author shows that policy transparency improves citizens’ preference for legal and political institutions and causes them to prioritize institutions over protest when they have grievances against the government. Multiple findings about the mechanisms suggest that policy information increases citizens’ perceived fairness of institutions in resolving their specific cases

Glaucoma after open globe injury
No full textAbstractOcular trauma remains a core root of avoidable blindness worldwide. Corneal scarring, lens injury, glaucoma, vitreous hemorrhage, retinal or choroidal detachment and endophthalmitis are sequel to ocular trauma that can lead to blindness. Very few studies have been published to tackle the risk of developing post-traumatic glaucoma after open globe injuries (OGI), however, there are many articles discussing closed eye injury. This review article aims to cover the incidence, risk factors, causes and treatment of glaucoma after open globe injury
The Use of Preoperative Prophylactic Systemic Antibiotics for the Prevention of Endopthalmitis in Open Globe Injuries: A Meta-Analysis
No full textTopic: This study reports the effect of systemic prophylactic antibiotics (and their route) on the risk of endophthalmitis after open globe injury (OGI). Clinical Relevance: Endophthalmitis is a major complication of OGI; it can lead to rapid sight loss in the affected eye. The administration of systemic antibiotic prophylaxis is common practice in some health care systems, although there is no consensus on their use. Methods: PubMed, CENTRAL, Web of Science, CINAHL, and Embase were searched. This was completed July 6, 2021 and updated December 10, 2022. We included randomized and nonrandomized prospective studies which reported the rate of post-OGI endophthalmitis when systemic preoperative antibiotic prophylaxis (via the oral or IV route) was given. The Cochrane Risk of Bias tool and ROBINS-I tool were used for assessing the risk of bias. Where meta-analysis was performed, results were reported as an odds ratio. PROSPERO registration: CRD42021271271. Results: Three studies were included. One prospective observational study compared outcomes of patients who had received systemic or no systemic preoperative antibiotics. The endophthalmitis rates reported were 3.75% and 4.91% in the systemic and no systemic preoperative antibiotics groups, a nonsignificant difference (P = 0.68). Two randomized controlled trials were included (1555 patients). The rates of endophthalmitis were 17 events in 751 patients (2.26%) and 17 events in 804 patients (2.11%) in the oral antibiotics and IV (± oral) antibiotics groups, respectively. Meta-analysis demonstrated no significant differences between groups (odds ratio, 1.07; 95% confidence interval, 0.54–2.12). Conclusions: The incidences of endophthalmitis after OGI were low with and without systemic antibiotic prophylaxis, although high-risk cases were excluded in the included studies. When antibiotic prophylaxis is considered, there is moderate evidence that oral antibiotic administration is noninferior to IV.

Clinical Characteristics, Visual Outcomes, and Prognostic Factors of Open Globe Injuries
No full textBackground and Objectives: Open globe injuries (OGI) remain an important cause of visual impairment and loss, impacting all ages. A better understanding of the factors influencing visual outcomes is important in an attempt to improve the results of the treatment of OGI patients. The author aimed to contribute to this knowledge with the analysis of clinical characteristics, prognostic factors, and visual outcomes of their cohort of OGI patients. Materials and Methods: A retrospective medical record review was performed for 160 patients (161 eyes) who sustained an open globe injury between January 2015 and December 2017 and presented to the Hospital of Lithuanian University of Health Sciences. Data analyzed included age, sex, type, cause, place of OGI, initial visual acuity (VA), final best-corrected visual acuity (BCVA), and tissue involvement. Open globe injuries were classified using the Birmingham Eye Trauma Terminology (BETT) and Ocular Trauma Classification System (OTCS). Univariate analysis was conducted to evaluate the prognostic factors. Results: The mean age of the patients was 41.9 years. The male-to-female ratio was found to be 8.4:1. The home was the leading place of eye injury (59.6%), followed by an outdoor environment (14.3%) and workplace (11.8%). Penetrating injury accounted for 43.5%, followed by intraocular foreign body injury (39.1%) and globe rupture (13%). Overall, 19.5% of patients regained a good final vision of ≥0.5, but for 48.1% of them, eye trauma resulted in severe visual impairment (BCVA ≤ 0.02). In the univariate analysis, a bad visual outcome of less than 0.02 was correlated with bad initial VA, iris dialysis, hypotony, vitreous hemorrhage, and vitreous prolapse at presentation. Phthisis bulbi was correlated with eyelid laceration, iris prolapse, iris dialysis, hyphema, vitreous prolapse, vitreous hemorrhage, and choroidal rupture at initial examination. Conclusions: Open globe injury remains an important preventable cause of ocular morbidity. This study provides data indicating that open globe injuries are a significant cause of visual impairment in our research group
Development of a plume identification algorithm for optical gas imaging of natural gas emissions that requires no human intervention
No full text2020 Spring.Includes bibliographical references.Recent growth in natural gas production in the United States has increased focus on reducing greenhouse gas emissions from the natural gas supply chain. Methane, the primary constituent of natural gas, is also a potent greenhouse gas. Optical gas imaging (OGI) is frequently used for emission detection in upstream and midstream sectors of the natural gas supply chain. Current OGI methods typically use mid-range infrared video cameras tuned to absorption lines of light hydrocarbons to make natural gas emissions visible to human operators. Prior studies of camera output have used human interpretation to determine if an emission is visible in the video stream, making it difficult to standardize measures of visibility between tests or to automate large test suites. This work presents a signal processing method which separates the background scene from the gas plume when used in controlled test conditions where video is collected in both leaking and non-leaking conditions. The method utilizes a novel frequency-based method that detects the high-frequency motion of the gas plume in the video stream. After background removal, the size of the gas plume can be quantified by thresholding the detected plume and measuring its size relative to the camera's field of view. The resulting metric eliminates the need for human evaluation of video streams. To demonstrate application of the method, multiple cameras were used to develop a relationship between emission rate and plume visibility over a range of viewing distances. Tests were conducted at the Methane Emissions Technology Evaluation Center, on CSU's Foothills Campus, using six identical OGI cameras (FLIR G300a camera cores with 38 mm lenses) to image the emission from multiple directions at a range 1 to 6 m. Gas was released from a mock well head at 17 to 196 g/h, with wind speeds of 1.8 to 3.0 m/s. Comparison with expert evaluation was used to set and validate the threshold levels; a 90% probability of detection requires a plume covering at least 13.8% of the camera's field of view. Testing indicated a linear relationship between emission rate and plume coverage fractions at a distance of 1 to 2 m, regardless of the viewing angle. Beyond 2 m, plume coverage drops rapidly, approaching the noise floor. While test conditions were limited, sufficient data was collected to demonstrate method functionality and its applicability to evaluating OGI emission detection systems
