This is the first part of a 3‐part comprehensive review of intraosseous carcinoma of the jaws. We have outlined 4 groups of intraosseous carcinoma of the jaws (metastatic, salivary‐type, odontogenic, and primary intraosseous carcinoma), emphasizing the need for accurate diagnosis and the problems associated with changing classification systems, standardization of diagnostic criteria and nomenclature, and the accuracy of existing literature. In this first part, the features of metastatic and the very rare salivary‐type carcinomas of the jaws are examined with particular emphasis on histologic and immunohistochemical characteristics, diagnostic difficulties, and uncertainties. © 2012 Wiley Periodicals, Inc.

In experimental studies, statin use has been associated with reduction of osteoclastic activity and promotion of bone formation around implants. Moreover, a large clinical study recently reported a substantially reduced risk of revision for aseptic loosening among statin users with THA. Our objective was to evaluate the influence of statin use on the development of femoral osteolysis within 5 years after THA. We conducted a case‐cohort study including all THAs presenting with femoral osteolysis at the 5 year visit (cases) and compared them with those without osteolysis (controls). Cases and controls were identified from a cohort of primary THAs operated between 2001 and 2005. Seven hundred thirty‐five THAs were included, mean age 68 years. Five years after surgery osteolysis had developed around the femoral component of 40 THAs (5.4%). Ever‐use of statins was much less frequent among cases (5 of 40, 12.5%) than among controls (199 of 695, 28.6%). The crude risk ratio of femoral osteolysis among statin users was 0.36 (95% CI 0.14; 0.92). After adjusting for age, sex, activity level, BMI, diagnosis, bearing surface, and type of stem, the adjusted risk ratio was 0.38 (95% CI 0.15; 0.99). In conclusion, statin use was associated with a reduced risk of developing femoral osteolysis 5 years after THA. Statins may be useful for reducing the risk of implant failure following THA. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 31: 814–820, 2013 相似文献

Background
Percutaneous endoscopic gastrostomy (PEG) remains a mainstay of enteral access. Thirty-day mortality for PEG has ranged from 16 to 43 %. This study aims to discern patient groups that demonstrate limited survival after PEG placement. The Enterprise Data Warehouse (EDW) concept allows an efficient means of integrating administrative, clinical, and quality-of-life data. On the basis of this concept, we developed the Vanderbilt Procedural Outcomes Database (VPOD) and analyzed these data for evaluation of post-PEG mortality over time.Methods
Patients were identified using the VPOD from 2008 to 2010 and followed for 1 year after the procedure. Patients were categorized according to common clinical groups for PEG placement: stroke/CNS tumors, neuromuscular disorders, head and neck cancers, other malignancies, trauma, cerebral palsy, gastroparesis, or other indications for PEG. All-cause mortality at 30, 60, 90, 180, and 360 days was determined by linking VPOD information with the Social Security Death Index. Chi-square analysis was used to determine significance across groups.Results
Nine hundred fifty-three patients underwent PEG placement during the study period. Mortality over time (30-, 60-, 90-, 180-, and 360-day mortality) was greatest for patients with malignancies other than head and neck cancer (29, 45, 57, 66, and 72 %) and least for cerebral palsy or patients with gastroparesis (7 % at all time points). Patients with neuromuscular disorders had a similar mortality curve as head and neck cancer patients. Stroke/CNS tumor patients and patients with other indications had the second highest mortality, while trauma patients had low mortality.Conclusions
PEG mortality was much higher in patients with malignancies other than head and neck cancer compared to previously published rates. PEG should be used with great caution in this and other high-risk patient groups. This study demonstrates the power of an EDW-based database to evaluate large numbers of patients with clinically meaningful results. 相似文献998.

Background
Although laparoscopic fundoplication effectively alleviates gastroesophageal reflux disease (GERD) in the great majority of patients, some patients remain dissatisfied after the operation. This study was undertaken to report the outcomes of these patients and to determine the causes of dissatisfaction after laparoscopic fundoplication.Methods
All patients undergoing laparoscopic fundoplication in the authors’ series from 1992 to 2010 were evaluated for frequency and severity of symptoms before and after laparoscopic fundoplication, and their experiences were graded from “very satisfying” to “very unsatisfying.” Objective outcomes were determined by endoscopy, barium swallow, and pH monitoring. Primary complaints were derived from postoperative surveys. Median data are reported.Results
Of the 1,063 patients undergoing laparoscopic fundoplication, 101 patients reported dissatisfaction after the procedure. The follow-up period was 33 months. The dissatisfied patients (n = 101) were more likely than the satisfied patients to have postoperative complications (9 vs 4 %; p < 0.05) and to have undergone a prior fundoplication (22 vs 11 %; p < 0.05). For the dissatisfied patients, heartburn decreased in frequency and severity after fundoplication (p < 0.05) but remained notable. Also for the dissatisfied patients, new symptoms (gas bloat/dysphagia) were the most prominent postoperative complaint (59 %), followed by symptom recurrence (23 %), symptom persistence (4 %), and the overall experience (14 %). Primary complaints of new symptoms were most common within the first year of follow-up assessment and less frequent thereafter. Primary complaints of recurrent symptoms generally occurred more than 1 year after fundoplication.Conclusions
Dissatisfaction is uncommon after laparoscopic fundoplication. New symptoms, such as dysphagia and gas/bloating, are primary causes of dissatisfaction despite general reflux alleviation among these patients. New symptoms occur sooner after fundoplication than recurrent symptoms and may become less common with time. 相似文献999.

Background
Although the retrograde approach to nerve sparing (NS) aimed at maximizing NS during robot-assisted radical prostatectomy (RARP) has been described, its significant benefits compared to the antegrade approach have not yet been investigated.Objective
To evaluate the impact of NS approaches on perioperative, pathologic, and functional outcomes.Design, setting, and participants
Five hundred one potent (Sexual Health Inventory for Men [SHIM] score >21) men underwent bilateral full NS and were followed up for a minimum of 1 yr. After propensity score matching, 344 patients were selected and were then categorized into two groups.Surgical procedure
RARP with antegrade NS (n = 172) or RARP with retrograde NS (n = 172).Outcome measurements and statistical analysis
Functional outcomes were assessed using validated questionnaires. Multivariable logistic regression models were applied.Results and limitations
Positive margin rates were similar (11.1% vs 6.9%; p = 0.192), and no correlation with the NS approach was found on regression analysis. At 3, 6, and 9 mo, the potency rate was significantly higher in the retrograde approach (65% vs 80.8% and 72.1% vs 90.1% and 85.3% vs 92.9%, respectively). The multivariable model indicated that the NS approach was an independent predictor for potency recovery at 3, 6, and 9 mo, along with age, gland size, and hyperlipidemia. After adjusting for these predictors, the hazard ratio (HR) for the retrograde relative to the antegrade approach was 2.462 (95% confidence interval [CI], 1.482–4.089; p = 0.001) at 3, 4.024 (95% CI, 2.171–7.457; p < 0.001) at 6, and 2.145 (95% CI, 1.019–4.514; p = 0.044) at 9 mo. Regarding continence, the recovery rates at each time point and the mean time to regaining it were similar, and the method of NS had no effect on multivariable analysis. The absence of randomization is a major limitation of this study.Conclusions
In patients with normal erectile function who underwent bilateral full NS, a retrograde NS approach facilitated early recovery of potency compared to that with an antegrade NS approach without compromising cancer control. 相似文献1000.
