Objectives: The aim of the study was to evaluate the analgesia and recovery effects of two doses (0.12 mg/kg and 0.24 mg/kg) of subcutaneous buprenorphine in cats undergoing ovariohysterectomy. Methods: This was an assessor-blinded, randomised, clinical study. A total of 83 cats were recruited and randomly allocated to receive 0.12 mg/kg buprenorphine or 0.24 mg/kg buprenorphine subcutaneously, followed 30 minutes later by 40 μg/kg medetomidine intramuscularly. Anaesthesia was induced with intravenous alfaxalone to effect and maintained with isoflurane in oxygen. All cats received meloxicam before surgery. Temperament score, quality of sedation, induction of anaesthesia, dose of alfaxalone and recovery were scored using simple descriptive scales. Atipamazole was administered following surgery. Physiological variables during anaesthesia were recorded. Cats were assessed postoperatively by the same blinded observer at 2, 4 and 24 hours using a modified Colorado Feline Acute Pain scale. The presence or absence of mydriasis was noted. Results: No significant differences were identified between groups. Three cats in the 0.12 mg/kg group and four in the 0.24 mg/kg group required rescue analgesia. Mydriasis persisting for at least 24 hours was evident in 75 cats. Conclusions and relevance: No differences in analgesia were detected between groups with these protocols; mydriasis was common in both groups.

Osteoporosis is an alarming issue in the society today. It is continuously increasing its signicance with increasing elderly population and is affecting both the sexes at different degrees. It is characterized by low bone mass with microarchitectural deterioration of bone leading to enhanced bone fragility, thus increasing the susceptibility to fracture. Taking into account the references available in various Ayurvedic classics it can be correlated to Asthikshaya. Asthikshaya occurs due to decrease in strength of Asthi Dhatu chiey due to Kala, Swabhava and Vata Prakopa. International Osteoporosis Foundation estimated that the annual direct cost of treating osteoporotic fractures has increased grossly. In India the general population is not much aware about the hazardous complications of osteoporosis. The modern pharmacological treatment is long and beyond the nancial reach of common people. Therefore the best way to deal with it is to prevent this as early as possible. To achieve this aim a clinical study was conducted to evaluate the effect of an Ayurvedic Formulation known as Eleg Fem capsules (Asthishrinkhalaadi Yoga) in osteoporotic patients. In the clinical trial 30 patients above the age of 40 years with low BMD T-Score were registered from OPD and IPD of Kayachikitsa department of Rajiv Gandhi Govt. Post Graduate Ayurvedic College and Hospital Paprola, Kangra. Out of 30 patients, 27 completed the trial and 3 patients were drop out. Criteria of assessment of patients was change in bone mineral density (BMD T- Score) and change in the score of Quality of Life Index Questionnaire for Osteoporosis (QUALEFFO-41). All the registered patients were given the formulation for 6 weeks. Improvement was observed with statistically signicant results on mean BMD TScore and moderately signicant result on Quality of Life Index scoring. The study revealed that the Eleg Fem capsules (Asthishrinkhalaadi Yoga) is a safe and effective therapy in the Osteoporotic patients.

The proficiency with which pilots can make takeoffs and landings using a periscope as the only source of outside visibility was studied under various conditions of flight. A detailed determination was made of the effects of variations in image magnification upon landing accuracy. Speed of transition to flight by periscope was related to flight experience. Effects of various weather, runway surface, and ambient lighting conditions upon flight by periscope were investigated.

We recruited a population of people who clinically suffer from the symptoms of erythromelalgia, red, hot, painful feet made worse by heat and improved by cooling, to better characterise this population and measure their quality of life (QOL). Ninety-two individuals completed the QOL surveys, and 56 individuals were clinically assessed. There was a 3 : 1 ratio of females to males with an average age of 61 years. The estimated prevalence of people who had clinical symptoms of erythromelalgia in the Dunedin community was 15/100,000. Only 27% of people had received a diagnosis for their symptoms despite seeking medical attention. People in the study population had worse quality of life than the general New Zealand population(P<0.001). In the majority of participants symptoms had a mild-moderate effect on their quality of life. The results of this study indicate that the number of people who have clinical symptoms of erythromelalgia is much greater than is commonly accepted and that the majority of these individuals go unrecognised by the medical profession despite seeking help. They have significantly diminished QOL with the majority of people having mild-to-moderate symptoms.

Nighttime visibility is an important consideration in collision reconstruction and personal injury investigation. Decreased contrast in low ambient lighting conditions can greatly affect human perception and response. Because ambient lighting levels change rapidly at dawn and dusk, forensic investigators must have an accurate knowledge of the time of day and the cloud conditions at the time of the incident before initiating a nighttime visibility assessment. Previously, human factors experts attempting re-enactments at dawn or dusk have had to wait for sky conditions that match those at the time of the incident, making the investigation of those cases extremely difficult, if not unfeasible. In this study, an ambient illumination equivalency tool has been developed based on a database of time-lapse light meter readings collected by the authors. This new tool can be used to facilitate nighttime visibility assessments on any day by providing a time adjustment factor to account for the changes in ambient illuminance due to differences in the cloud conditions between the day of the incident and the day of the re-enactment.
