This report is an overview of enterovirus (EV) detection in Tunisian polio-suspected paralytic cases (acute flaccid paralysis (AFP) cases), healthy contacts and patients with primary immunodeficiencies (PID) during an 11-year period. A total of 2735 clinical samples were analyzed for EV isolation and type identification, according to the recommended protocols of the World Health Organization. Three poliovirus (PV) serotypes and 28 different nonpolio enteroviruses (NPEVs) were detected. The NPEV detection rate was 4.3%, 2.8% and 12.4% in AFP cases, healthy contacts and PID patients, respectively. The predominant species was EV-B, and the circulation of viruses from species EV-A was noted since 2011. All PVs detected were of Sabin origin. The PV detection rate was higher in PID patients compared to AFP cases and contacts (6.8%, 1.5% and 1.3% respectively). PV2 was not detected since 2015. Using nucleotide sequencing of the entire VP1 region, 61 strains were characterized as Sabin-like. Among them, six strains of types 1 and 3 PV were identified as pre-vaccine-derived polioviruses (VDPVs). Five type 2 PV, four strains belonging to type 1 PV and two strains belonging to type 3 PV, were classified as iVDPVs. The data presented provide a comprehensive picture of EVs circulating in Tunisia over an 11-year period, reveal changes in their epidemiology as compared to previous studies and highlight the need to set up a warning system to avoid unnoticed PVs. 相似文献

Preprocedural spinal ultrasound appears to decrease the failure rate and complications of neuraxial anesthesia compared to the conventional landmark technique. It is especially beneficial in difficult cases where conventional palpation technique may fail. We recently encountered a parturient with multiple lumbar and cervical spinal metastatic lesions presenting for cesarean section in the third trimester. We used spinal ultrasound to define the appropriate intervertebral space and measure the distance to the ligamentum flavum-dura mater complex. This greatly helped in administering a safe spinal anesthetic and avoiding general anesthesia which might have been hazardous in this patient. 相似文献

Aim
The purpose of this study is to evaluate the clinical and radiological outcomes of cemented bipolar arthroplasty as a primary treatment for unstable intertrochanteric fracture in the elderly patients.Methods
Twenty hips with unstable intertrochanteric fractures were followed for more than 2 years after cemented bipolar hemiarthroplasty. The mean age was 69 years, and the mean follow-up period was 30.5 months. We evaluated the results by Harris hip score, complications, and radiologic findings.Results
At the last follow-up, the mean Harris hip score was 83.3 points. Radiologically, there was no case of osteolysis. All stems were stable without significant changes in alignment or progressive subsidence.Conclusions
Bipolar hemiarthroplasty with calcar reconstruction is a good option for unstable intertrochanteric fractures in elderly patients with severe osteoporosis with strict indication selection. Longer-term studies with larger numbers of patients are required to address the issues of late complications. 相似文献6.

Uterine leiomyoma with massive lymphoid infiltration is a rare and unusual pathological finding; only 20 cases have been reported in the literature. We report a case of this unusual lesion in a 35-year-old woman who underwent a myomectomy. On gross examination, the tumor was of white color and firm consistency. Histological sections showed interlacing bundles of spindle shaped cells of low density with moderate to severe lymphocytic infiltrate associated to lymphoid follicles and few plasma cells. Immunohistochemically, the diffusely infiltrating lymphoid cells were predominantly of T cell phenotype. The interspersed spindle shaped cells were positive with alpha smooth muscle actin, desmin and h-caldesmon. The cause of this unusual lesion is not clear, but the recognition of its distinct histological features is important to avoid possible confusion with differential diagnosis including malignant lymphoma, inflammatory pseudotumor and pyomyoma. 相似文献

Between 2002 and 2007, fifty elderly patients with displaced femoral neck fractures were treated with hip replacement at Emergency
Hospital, Mansoura University. Patients were randomly selected, 25 patients had either cemented or cementless bipolar prosthesis,
and another 25 patients had either cemented or cementless fixed-head prosthesis. There were 34 women and 16 men with an average
age of 63.5 years (range between 55 and 72 years). All patients were followed up both clinically and radiologically for an
average 4.4 years (range between 2 and 6 years). At the final follow-up, the average Harris hip score among the bipolar group
was 92 points (range between 72 and 97 points), while the fixed-head group was 84 points (range between 65 and 95 points).
Radiologically, joint space narrowing more than 2 mm was found in only 8% (2 patients) among the bipolar group, and in 28%
(7 patients) of the fixed-head group. Through the follow-up period, total hip replacement was needed in two cases of the bipolar
group and seven cases of the fixed-head group. Bipolar hemiarthroplasty offered a better range of movement with less pain
and more stability than the fixed-head hemiarthroplasty in elderly patients with displaced femoral neck fractures. 相似文献

Background: Systematic reviews (SRs) and/or meta-analyses of in vitro research have an important role in establishing the foundation for clinical studies. In this study, we aimed to evaluate the reporting quality of SRs of in vitro studies using the PRISMA checklist.Method: Four databases were searched including PubMed, Virtual Health Library (VHL), Web of Science (ISI) and Scopus. The search was limited from 2006 to 2016 to include all SRs and/or meta-analyses (MAs) of pure in vitro studies. The evaluation of reporting quality was done using the PRISMA checklist.Results: Out of 7702 search results, 65 SRs were included and evaluated with the PRISMA checklist. Overall, the mean overall quality score of reported items of the PRISMA checklist was 68%. We have noticed an increasing pattern in the numbers of published SRs of in vitro studies over the last 10 years. In contrast, the reporting quality was not significantly improved over the same period (p?=?.363). There was a positive but not significant correlation between the overall quality score and the journal impact factor of the included studies.Conclusions: The adherence of SRs of in vitro studies to the PRISMA guidelines was poor. Therefore, we believe that using reporting guidelines and journals paying attention to this fact will improve the quality of SRs of in vitro studies. 相似文献

In May 2015 in United Arab Emirates, asymptomatic Middle East respiratory syndrome coronavirus infection was identified through active case finding in 2 men with exposure to infected dromedaries. Epidemiologic and virologic findings suggested zoonotic transmission. Genetic sequences for viruses from the men and camels were similar to those for viruses recently detected in other countries. 相似文献
