Since the outbreak of coronavirus disease 2019 (COVID-19) in December 2019 in China, various measures have been adopted in order to attenuate the impact of the virus on the population. With regard to spine surgery, French physicians are devoted to take place in the national plan against COVID-19, the French Spine Surgery Society therefore decided to elaborate specific guidelines for management of spinal disorders during COVID-19 pandemic in order to prioritize management of patients. A three levels stratification was elaborated with Level I: Urgent surgical indications, Level II: Surgical indications associated to a potential loss of chance for the patient and Level III: Non-urgent surgical indications. We also report French experience in a COVID-19 cluster region illustrated by two clinical cases. We hope that the guidelines formulated by the French Spine Surgery Society and the experience of spine surgeons from a cluster region will be helpful in order optimizing the management of patients with urgent spinal conditions during the pandemic. 相似文献

This paper is one of a series of three, covering very comprehensively human resource practices in a global and generic context. The series of papers presents practices which are directly of relevance to the health-care context, and which are based on proven, effective and pioneering approaches. The first paper covers practices based on British and European experiences, gathered from world-class organisations that have either been finalists or went on to win prestigious quality awards such as the British and European Quality Awards. The benchmarking analysis presented in this paper is based on the sub-criteria prescribed by the European Quality Awards Model, which include: how people resources are planned and improved; how the skills and capabilities of people are preserved and developed through recruitment, training and career progression; how people and teams agree targets and continuously review performance; how the involvement of everyone in continuous improvement is prompted and people empowered to take appropriate action; how effective top-down and bottom-up communication is achieved. 相似文献

There are two histological types of pyogenic granuloma (PG) of the oral cavity: the lobular capillary hemangioma (LCH) and non-LCH type. The aim of the present study was to examine and compare the clinical features, etiological factors, diameter of vascular elements and immunohistochemical features of LCH and non-LCH histological types of PG to determine whether they are two distinct entities. Thirty cases of LCH and 26 cases of non-LCH PG were retrieved and retrospectively studied. Clinically, LCH PG occurred more frequently (66.4%) as sessile lesion whereas non-LCH PG occurred as pedunculated (77%). Non-LCH PG was associated more frequently (86.4%) with etiological factors. The lobular area of the LCH PG contained a greater number of blood vessels with small luminal diameter than did the central area of non-LCH PG. In the central area of non-LCH PG a significantly greater number of vessels with perivascular mesenchymal cells non-reactive for alpha-smooth muscle actin and muscle-specific actin was present than in the lobular area of LCH PG. The differences found in the present study suggest that the two histological types of PG represent distinct entities. 相似文献

PURPOSE: To determine changes of the urothelial barrier during the early as well as late radiation response in mouse urinary bladder. MATERIALS AND METHODS: Groups of mice were irradiated with a single dose of 20Gy and sacrificed between days 0 and 360. Urothelial cell numbers were counted, and the fraction of urothelium with a positive immunohistochemical signal for uroplakin-III (UP-III) on the luminal surface of the bladder was defined. Also, cytoplasmic UP-III staining signal in urothelium was quantified using an arbitrary score (0-3). RESULTS: Irradiation resulted in a significant decrease in the number of superficial umbrella cells during the early response phase (days 0-31) as well as during the initial late radiation reaction (days 90, 120). Progressive loss of the UP-III layer on the bladder luminal surface correlated with the decrease in the number of umbrella cells (p=0.002). Also, increased cytoplasmic staining of UP-III in the urothelium was seen after irradiation, correlating negatively with the reduction of the superficial UP-III layer (p<0.0001). CONCLUSION: Irradiation of the urinary bladder results in morphological impairment of the urothelial barrier that is associated with a loss of superficial umbrella cells during the early as well as initial late radiation response phase. 相似文献

Unusual complications of peritoneal shunts are a well-known occurrence. The authors report a rare case of intra-cardiac migration of a distal shunt catheter, which occurred during the initial post-operative days. The physiopathology of this complication and its management are reported. 相似文献

BackgroundLungs are the second most common site for hydatid disease after the liver. Giant hydatid cyst (GHC) of the lung is a special clinical entity in children and is related to higher lung tissue elasticity.AimTo compare clinical and imaging features, types of surgical interventions, and postoperative complications in pulmonary GHC and non-giant pulmonary hydatid cysts (NGHC) in children.MethodsA retrospective study was undertaken. The data analyzed were taken from medical records of children with pulmonary hydatid cyst (PHC) hospitalized in a pulmonary department in Tunisia between January 2004 and February 2019. Cysts were divided according to their size into GHC ( ≥10 cm) and NGHC (< 10 cm).ResultsIn the study period, 108 PHC were recorded in 84 children. GHC accounted for 21 (19.4%) and NGHC for 87 (80.6%). The median of age of the children was 11 years (IQR 1–9, IQR 3–14) and the mean age was 11.6 years (10.5 in GHC vs. 11.4 years in NGHC). Hemoptysis was found in 25% of the GHC group vs. 48.4% of the NGHC group (P = 0.27). Cysts were multiple in 23.8% of cases and predominated in the right in 64.3% of cases and in the inferior lobes in 71.4% of the cases. GHCs were less frequently complicated (60% vs. 78.1% in NGHC, P ≤ 0.11), although not significantly. Parenchymal resection was realized in 50% of GHC vs. 18.8% of NGHC (P = 0.006). No significant difference was found in postoperative complications between the two groups and there was no recurrence in either group.ConclusionGHC is a special clinical entity in children. It requires major surgery with parenchymal resection, and therefore early diagnostic and therapeutic management is warranted. 相似文献
