A 47‐year‐old white male with a history of uveitis, hypercalcemia and nephrolithiasis presented with acute onset partial seizure. On exam he had decreased sensation to light touch on his left lower extremity. A Brain MRI revealed a right frontal mass, which was initially thought to be a metastatic lesion or a primary brain tumor. However, biopsy of the lesion revealed it to be a non‐caseating granulomatous lesion consistent with neurosarcoidosis. 相似文献

PURPOSE: To examine the relationship between calculated doses to the neurovascular bundles (NVBs) and the penile bulb (PB) and the development of erectile dysfunction (ED) after low-dose-rate prostate brachytherapy (LDRPB) alone. METHODS AND MATERIALS: Between September 1997 and June 1999, 84 men were treated with LDRPB alone. Inclusion criteria for this study were (1) no ED according to a self-administered questionnaire before PB, (2) treatment with PB alone (125I; 144 Gy), (3) postimplant CT scan of the prostate 1 month after PB, and (4) minimum of 24 months of continuous follow-up. Fifty men met all inclusion criteria. ED was assessed by a self-administered questionnaire completed before and at each follow-up visit after LDRPB. Radiation doses to the NVB and PB were calculated on the basis of axial postimplant CT images. Multiple variables (patient-related and dosimetric quantifiers) that may predict for the development of ED were examined by univariate analysis. RESULTS: Thirty of the 50 men (60%) were potent at last follow-up. The only patient-related variable that predicted for the development of ED was patient age (<65 vs. >65 years; p=0.03). The calculated mean maximum doses to the NVB and PB were 684 Gy (range, 195-1277 Gy) and 498 Gy (range, 44-971 Gy), respectively. The mean calculated doses to 50% of the NVB and PB were 158 Gy (range, 76-240 Gy) and 43 Gy (range, 19-101 Gy), respectively. The calculated mean maximum, mean minimum, and mean doses to 50% of the NVB or PB did not differ between those men who developed ED and those men who did not develop ED. None of the dosimetric variables examined predicted the development of ED after LDRPB. CONCLUSIONS: In our experience, higher calculated doses to the NVB or PB are not associated with ED after LDRPB. 相似文献

A 45-year-old male presented with subacute onset of a right-sided hemiparesis, right homonymous hemianopsia, and slurred speech. The brain imaging revealed two separate intraparenchymal enhancing lesions. The cerebrospinal fluid rapid plasma reagin and venereal disease research laboratory test were positive and consistent with syphilitic gumma, and the patient responded dramatically to penicillin G. Despite, currently low incidence of syphilis; CNS gummas should be in the differential of mass lesions as they are eminently treatable. 相似文献

Objective
To present the outcomes of scleral buckle (SB) removal with and without concurrent prophylactic laser retinopexy.Design
Retrospective, interventional case series.Participants
Eighty-seven eyes of 87 patients who had SB removal after primary rhegmatogenous retinal detachment repair.Methods
All patients who had SB removal after primary rhegmatogenous retinal detachment repair from both Wills Eye Institute and University of Alberta from 2000 to 2011 were identified. All patients had a minimum of 6 months of follow-up.Results
Eighty-seven patients met the study criteria. Primary indications for SB removal were extrusion (76%, n = 66), diplopia (8%, n = 7), infection (6%, n = 5), a combination of extrusion and infection (6%, n = 5), and others (5%, n = 4). Only 3 of 87 eyes (3.4%) developed a recurrent retinal detachment after SB removal. Only 1 eye (2.2%) from the group that received laser retinopexy (n = 45) at the time of SB removal had a retinal redetachment, whereas 2 eyes (4.2%) in the group that did not receive laser (n = 42) had a recurrent retinal detachment (p = 0.61).Conclusions
The overall rate of recurrent retinal detachment after SB removal was low. No significant difference in recurrent retinal detachment was found between the eyes that received prophylactic laser retinopexy compared with those that did not at the time of SB removal. 相似文献47.

Total hip arthroplasty (THA) is an increasingly common procedure among elderly individuals. Although conversion THA is currently bundled in a diagnosis related group (DRG) with primary THA, there is a lack of literature supporting this classification and it has yet to be identified whether conversion THA better resembles primary or revision THA. This editorial analyzed the intraoperative and postoperative factors and functional outcomes following conversion THA, primary THA, and revision THA to understand whether the characteristics of conversion THA resemble one procedure or the other, or are possibly somewhere in between. The analysis revealed that conversion THA requires more resources both intraoperatively and postoperatively than primary THA. Furthermore, patients undergoing conversion THA present with poorer functional outcomes in the long run. Patients undergoing conversion THA better resemble revision THA patients than primary THA patients. As such, patients undergoing conversion THA should not be likened to patients undergoing primary THA when determining risk stratification and reimbursement rates. Conversion THA procedures should be planned accordingly with proper anticipation of the greater needs both in the operating room, and for in-patient and follow-up care. We suggest that conversion THA be reclassified in the same DRG with revision THA as opposed to primary THA as a step towards better allocation of healthcare resources for conversion hip arthroplasties. 相似文献
