We report a case of bilateral loss of pupillary light reflex and accommodation following 360° peripheral retinal laser therapy. A 24 years old male underwent prophylactic laser barrage for peripheral retinal lattice degenerations. Soon after the procedure, he developed bilateral loss of pupillary light reflex and accommodation. The patient faced difficulty while doing near work. On instillation of 0.125% pilocarpine, both pupils demonstrated the phenomenon of denervation supersensitivity. Damage to the short ciliary nerves was the most likely mechanism responsible for this adverse outcome. 相似文献

Paediatric Life Support (PLS) courses are thought to significantly increase knowledge of paediatric resuscitation for all professional groups. PLS and Newborn Life Support (NLS) guidelines were revised and updated in 2005. In a telephonic survey, the retention and awareness of the changes in PLS guidelines were evaluated among 100 junior paediatric doctors. Overall, second on-call doctors tended to score higher than the first on-call doctors (score 6.55 ± 2.25 vs. 5.89 ± 2.17 respectively, p = 0.062). Doctors who attended PLS courses after 2005 tended to have higher scores. There is a need to streamline formalised regular updates (e.g. annual online written multiple choice questions) and in-house rehearsals using mock emergency scenarios at local, regional and national level. 相似文献

Pain is experienced by people suffering from spinal cord injury leading to disability and affecting the person's functional ability, independence, psychological well - being, ability to return to work and quality of life. Pain management in these patients is notoriously difficult due to multiple factors and varied mechanism leading to pain. Only few treatments have been assessed in randomized, controlled trials and management is based on different case reports. We are reporting our experience of managing 2 patients with neuropathic pain following traumatic spinal cord injury. Both the patients were refractory to conventional pain medications but there was significant reduction in pain following lignocaine infusion in the first patient and with ketamine in the second patient. 相似文献

Background
Many patients do not intensify their insulin regimens. It is believed that lack of adherence may be largely due to fear of hypoglycemia. We hypothesized that utilization of an automated bolus calculator (bolus advisor) might reduce fear of hypoglycemia and encourage patients to achieve improved glycemic control.Method
We surveyed 1,412 type 1 diabetes mellitus (T1DM) patients treated with multiple daily insulin injection therapy at 270 hospitals in the United Kingdom and Republic of Ireland to assess their attitudes and behaviors regarding insulin therapy after use of a bolus advisor (Accu-Chek® Aviva Expert blood glucose meter and bolus advisor system, Roche Diagnostics). The device automatically calculates bolus dosages based on current blood glucose values, anticipated meal intake, and other parameters.Results
Five hundred eighty-eight T1DM patients responded to the survey. Respondents were predominantly female, age <1 to 70 years, with diabetes duration of <1 to >15 years. Respondents had 4–12 weeks prior experience using the bolus advisor. 76.7% of respondents indicated current bolus advisor use to calculate insulin boluses for meals/snacks always or quite often. 52.0% of respondents indicated that fear of hypoglycemia was reduced (39.0%) or significantly reduced (13.0%). 78.8% indicated that confidence in the insulin dose calculation improved (50.8%) or significantly improved (28.0%). 89.3% indicated that the bolus advisor made bolus calculation easy or very easy compared with manual calculation.Conclusions
Most patients felt that using the bolus advisor was easier than manual bolus calculation, improved their confidence in the accuracy of their bolus dosage, and reduced their fear of hypoglycemia. Randomized trials are needed to confirm these perceptions and determine whether bolus advisor use improves clinical outcomes. 相似文献198.

ObjectiveTo compare the presence of Theileria ovis in small ruminants from two provinces of Pakistan and to determine the risk factors associated with the spread of theileriosis.MethodsIn present study, a total of 210 blood samples were collected from sheep (n=99) and goats (n=111) from 5 sampling sites in Punjab (Dera Ghazi Khan, Layyah, Multan and Rahim Yar Khan districts) and Khyber Pukhtoon Khwa (district Kohat) provinces, in Pakistan, from randomly selected herds. Data on the characteristics of the animals (species, gender, age, tick presence or absence, prior treatment for babesiosis) and the herd (location, size, species of animals, dogs associated with the herds, tick burden of dogs associated with the herds) was collected through questionnaires.ResultsTwelve blood samples (6% of total), 11 from district Kohat, produced the 520 base pairs DNA fragment specific for small subunit ribosomal RNA (ssu rRNA) gene of Theileria ovis, by PCR amplification, of which 11 were sheep and 1 was goat indicating that sheep are more significantly (P=0.001) prone to this parasite. On the other hand parasite was detected only in 2 out of 210 samples (1%) by blood smear screening confirming PCR as the reliable detection tool.ConclusionsPCR is more sensitive and reliable diagnostic tool for detection of Theileria sp. as compared to blood smear screening. Incidence of Theileria ovis is very high in Khyber Pukhtoon Khwa as compared to Punjab province. It was also observed that presence of ticks on animals was the only significant risk factor associated with the theileriosis in small ruminants. 相似文献
