Purpose
Percutaneous biopsy obtained from a single location is prone to sampling error in large heterogeneous renal masses, leading to nondiagnostic results or failure to detect poor prognostic features. We evaluated the accuracy of percutaneous biopsy for large renal masses using a modified multi-quadrant technique vs. a standard biopsy technique.Materials and methods
Clinical and pathological data for all patients with cT2 or greater renal masses who underwent percutaneous biopsy from 2009 to 2014 were reviewed. The multi-quadrant technique was defined as multiple core biopsies from at least 4 separate solid enhancing areas in the tumor. The incidence of nondiagnostic findings, sarcomatoid features and procedural complications was recorded, and concordance between biopsy specimens and nephrectomy pathology was compared.Results
A total of 122 biopsies were performed for 117 tumors in 116 patients (46 using the standard biopsy technique and 76 using the multi-quadrant technique). Median tumor size was 10 cm (IQR: 8–12). Biopsy was nondiagnostic in 5 of 46 (10.9%) standard and 0 of 76 (0%) multi-quadrant biopsies (P = 0.007). Renal cell carcinoma was identified in 96 of 115 (82.0%) tumors and nonrenal cell carcinoma tumors were identified in 21 (18.0%). One complication occurred using the standard biopsy technique and no complications were reported using the multi-quadrant technique. Sarcomatoid features were present in 23 of 96 (23.9%) large renal cell carcinomas studied. Sensitivity for identifying sarcomatoid features was higher using the multi-quadrant technique compared to the standard biopsy technique at 13 of 15 (86.7%) vs. 2 of 8 (25.0%) (P = 0.0062).Conclusions
The multi-quadrant percutaneous biopsy technique increases the ability to identify aggressive pathological features in large renal tumors and decreases nondiagnostic biopsy rates. 相似文献65.

This paper reviews the mechanisms of anaphylactic shock in terms of the immunoglobulin and non-immunoglobulin triggering events; and the cellular events based on the rise in intracellular cyclic AMP and calcium that release preformed granule associated mediators and the rapidly formed, newly synthesised mediators predominantly based on arachidonic acid metabolism. These primary mediators recruit other cells with the release of secondary mediators that either potentiate or ultimately curtail the anaphylactic reaction. The roles of these mediators in the various causes of cardiovascular collapse are examined. The treatment of anaphylactic shock involves oxygen, adrenaline and fluids. The importance and safety of intravenous adrenaline are discussed. Combined H1 and H2 blocking antihistamines and steroids have a limited role. Glucagon and other adrenergic drugs are occasionally used, and there are several new experimental drugs. 相似文献

While most births result in a live baby, stillbirth (the birth of a dead baby) occurs in nearly 1 in 110 pregnancies. This study examined whether levels of maternal anxiety and depression are lower amongst mothers who received social support after stillbirth. Using non-probability sampling, data were collected from 769 mothers residing within the USA who experienced a stillbirth within the past 18 months and for whom we have complete data. The study Maternal Observations and Memories of Stillbirth and the website http://www.momstudy.com containing the questionnaire were open in the period 8 February 2004–15 September 2005. Congruent with the family stress and coping theory, mothers of stillborn babies who perceived family support in the period after stillbirth experienced levels of anxiety and depression that were notably lower than those of their counterparts. Nurses, physicians and support groups also were important sources of support after a stillbirth; however, these sources of support alone were not statistically significant in reducing anxiety and depression in grieving mothers. Community interventions should focus on the grieving mother and her family system , including her partner and surviving children. 相似文献

The case reports of 22 patients with cervical pregnancies treated by
methotrexate (MTX) administration and published in English literature
between 1983 and 1995 were reviewed, by either original paper review or
follow-up under international collaboration, to determine the subsequent
reproductive performance and obstetric outcomes. Out of 22 cases, 18 (78%)
MTX chemotherapy attempts succeeded with complete remission and four (22%)
failed. Of the 13 women who wished to conceive and could be followed for at
least 3 years, nine succeeded in having live births without congenital
malformations, one spontaneously aborted and three suffered infertility. In
general, MTX chemotherapy alone or combined with adjuvant methods such as
subsequent cervical curettage or cervical tamponade, or intracervical
potassium chloride injection, appears to be a convenient and effective
method for the treatment of the majority of cervical pregnancies before 12
weeks gestation, and has not been shown to have detrimental effects on
subsequent reproductive capacities, obstetric outcomes and progeny health
for those cases with successful preservation of the uteri.
