The feasibility of an individualised carer support service delivered in community pharmacies was assessed from the perspective of carer participants using a pre–post questionnaire and semistructured interviews. Eligible pharmacies were required to offer a medication management service relevant to carers and have a semiprivate space for conversations. Carers were required to self‐identify as an unpaid support person for someone with a chronic condition or disability. Between September 2016 and March 2017, staff from 11 community pharmacies in South‐East Queensland, Australia were trained, and provided with ongoing mentoring from a pharmacist and carer to support service implementation. Identification of carers and support to achieve a personal and care‐giving goal were key features of the service. Questionnaires included the EQ‐5D‐3L, the Bakas Caregiving Outcomes Scale, and questions relating to goal achievement, carer roles, and responsibilities. Seven follow‐up carer interviews were undertaken between March and May 2017 and analysed thematically. Pre–post questionnaires were available for 17 carers (one withdrew, two incomplete). Of the 29 goals set, 10 were achieved and 14 partially achieved. EQ‐5D‐3L scores were unchanged, while 7 of the 15 items comprising the Bakas score improved (p < 0.05). Carer service evaluation was generally favourable, and these two main interview themes were the impact of caring and pharmacy experience. The impact of caring, while variable, was significant. Pharmacy experiences were mostly positive and the opportunity for carers to further engage with pharmacy staff was appreciated. The service was feasible and initial reported benefits to carers may support further research potentially in terms of a larger controlled trial. 相似文献

Three‐dimensional multislice spiral computed tomographic angiography (3D‐MSCTA) is a minimally invasive method of vascular mapping. The aim of this study was to evaluate the clinical usefulness of this imaging technique in delineating the recipient vessels for safer free tissue transfer to complicated regions. 3D‐MSCTA was performed preoperatively in 26 patients scheduled for free tissue transfer, in whom the availability of the recipient vessels were considered to be uncertain, and 23 of these were operated on. Radiographic and operative findings regarding the availability of the recipient vessels for anastomosis were correlated in 21 of these 23 patients. 3D‐MSCTA yielded two false‐positive results; anastomosis was not possible because of widespread atherosclerotic plaques and poor flow observed in the recipient arteries despite the good caliber observed in 3D‐MSCTA images. 3D‐MSCTA provides a noninvasive means of preoperatively assessing recipient site vessels for anatomic variations and suitability before free tissue transfer and enables the surgeon to establish an appropriate treatment plan. But it is not 100% reliable yet and the possibility of false‐positive results should be kept in mind, especially inthe patients with peripheral vascular disease. 3D‐MSCTA has the potential to replace digital subtraction angiography for planning of microvascular reconstructions and newer devices with higher resolutions will probably increase the reliability of this technique. © 2009 Wiley‐Liss, Inc.

Since percutaneous nephrolithotomy (PNL) is a surgical intervention, it may show deteriorative effects on renal function in
the early postoperative period. In this study, the deteriorative effects of PNL on renal function were investigated in the
geriatric population, and it was compared to the non-geriatric population.
A total of 711 patients [64 in the geriatric group (female/male ratio: 33/31, mean age: 70.4 ± 4.2 years), 647 in the non-geriatric
group (female/male ratio: 267/380, mean age: 40.9 ± 12.7 years)] were included in the study. Demographic data, biochemical
parameters, stone diameters, duration of the operation and estimated glomerular filtration rates (eGFR) were recorded both
preoperatively and postoperatively.
The eGFR ratio (post-/preoperative) was 1.13 ± 1.00 in the geriatric group, 0.98 ± 0.20 in the non-geriatric group (P < 0.001). Although the mean stone diameter was larger in the geriatric group than the non-geriatric group (10.08 ± 6.5 mm,
8.28 ± 5.54 mm, P = 0.037), the mean duration of the operation was shorter in the geriatric group than in the non-geriatric group (55.7 ± 13.6 min,
61.3 ± 20.9 min, P = 0.036). Hematocrit, hemoglobin, urea levels, and grade of hydronephrosis were not different between the groups.
Renal function impairment is expected to be common in the geriatric patient population since they already have lower basal
renal function. In the present study, the ratio of postoperative to preoperative eGFR was higher in the geriatric group. Hematocrit,
hemoglobin, and urea levels and degree of hydronephrosis of these two groups did not show a great difference. The relatively
short duration of the operation in the geriatric group and the diversity of perioperative and postoperative care of these
two groups may explain the difference. 相似文献

Transsphenoidal encephaloceles are rare and the transsellar variety is the least common. We present a 1-year-old male patient with transsellar transsphenoidal encephalocele which herniated into the oral cavity through the congenital split palate. The patient was operated on using a combined transcranial and transpalatal approach without mortality or permanent morbidity. Clinical findings, imaging reviews, surgical repair techniques and postoperative morbidity are discussed with the relevant literature. We conclude that repair of a transsphenoidal encephalocele should be coordinated between a team of neurosurgeons and otorhinolaryngologists. Our surgical outcome supports a transcranial approach for the treatment of these difficult lesions, with transpalatal dissection and exposure. 相似文献
