A Comprehensive Treatment Protocol for Endometriosis Patients Decreases Pain and Improves Function.

Purpose: The purpose of this paper is to evaluate the efficacy of a multimodal, outpatient neuromuscular protocol in treating remaining sensitization and myofascial pain in endometriosis patients post-surgical excision. Patients and Methods: A retrospective longitudinal study was conducted for women aged 22 to 78 with a history of surgically excised endometriosis. 60 women with an average duration of pain of 8.63 ± 7.65 years underwent a treatment protocol consisting of ultrasound guided trigger point injections, peripheral nerve blocks, and pelvic floor physical therapy for 6 weeks. Concomitant cognitive behavioral therapy once weekly for a total of 12 weeks was also undertaken. Pain intensity and pelvic functionality were assessed at new patient consults and 3-month follow ups using Visual Analogue Scale (VAS) and Functional Pelvic Pain Scale (FPPS). Results: At new patient consults, average VAS and FPPS were 7.45 ± 2.11 (CI 6.92-7.98) and 14.35 ± 6.62 (CI 12.68 -16.02), respectively. At 3-month follow ups, average VAS and FPPS decreased to 4.12 ± 2.44 (CI 3.50-4.73; p < 0.001) and 10.3 ± 6.55 (CI 8.64-11.96; p < 0.001), respectively. Among FPPS categories, sleeping, intercourse, and working showed the highest statistical significance. Conclusion: Data suggests the multimodal protocol was effective in treating the remaining underlying sensitization and myofascial pain seen in Endometriosis patients post-surgical excision, particularly in decreasing pain and improving function during work and intercourse.

Sertoliform Cystadenoma of the Rete Testis: Report of a Case and Review of the Literature.

Sertoliform cystadenoma is a rare benign tumor of the rete testis with 8 previously reported cases and an additional 14 cases reported in an abstract form. It usually presents with a unilateral scrotal mass, clinically and radiologically indistinguishable from malignant testicular tumors. We report a 39-year-old man who presented with a right testicular mass. The patient underwent radical inguinal orchiectomy. Grossly, no masses were appreciated. After histologic examination with subsequent immunohistochemical staining, a sertoliform cystadenoma of the rete testis was diagnosed.

Combining Mean and Standard Deviation of Hounsfield Unit Measurements from Preoperative CT Allows More Accurate Prediction of Urinary Stone Composition Than Mean Hounsfield Units Alone.

INTRODUCTION AND OBJECTIVES: The mineral composition of a urinary stone may influence its surgical and medical treatment. Previous attempts at identifying stone composition based on mean Hounsfield Units (HUm) have had varied success. We aimed to evaluate the additional use of standard deviation of HU (HUsd) to more accurately predict stone composition. METHODS: We identified patients from two centers who had undergone urinary stone treatment between 2006 and 2013 and had mineral stone analysis and a computed tomography (CT) available. HUm and HUsd of the stones were compared with ANOVA. Receiver operative characteristic analysis with area under the curve (AUC), Youden index, and likelihood ratio calculations were performed. RESULTS: Data were available for 466 patients. The major components were calcium oxalate monohydrate (COM), uric acid, hydroxyapatite, struvite, brushite, cystine, and CO dihydrate (COD) in 41.4%, 19.3%, 12.4%, 7.5%, 5.8%, 5.4%, and 4.7% of patients, respectively. The HUm of UA and Br was significantly lower and higher than the HUm of any other stone type, respectively. HUm and HUsd were most accurate in predicting uric acid with an AUC of 0.969 and 0.851, respectively. The combined use of HUm and HUsd resulted in increased positive predictive value and higher likelihood ratios for identifying a stone's mineral composition for all stone types but COM. CONCLUSIONS: To the best of our knowledge, this is the first report of CT data aiding in the prediction of brushite stone composition. Both HUm and HUsd can help predict stone composition and their combined use results in higher likelihood ratios influencing probability.

Partial and Radical Nephrectomy for Unilateral Synchronous Multifocal Renal Cortical Tumors.

OBJECTIVE: To evaluate clinicopathologic characteristics and treatment outcomes of patients undergoing partial nephrectomy (PN) or radical nephrectomy (RN) for unilateral synchronous multifocal renal tumors. METHODS: We retrospectively reviewed medical records for 128 patients with nonmetastatic, unilateral, synchronous, multifocal renal tumors who underwent surgical resection at our institution from 1995 to 2012. Five patients with hereditary renal cell carcinoma were excluded. Differences between patient and tumor characteristics from the 2 nephrectomy groups were evaluated. Outcomes in terms of recurrence-free survival, overall survival, and chronic kidney disease upstaging were estimated using Kaplan-Meier methods. The log-rank test was used for group comparisons. RESULTS: The study cohort included 78 PN patients (63%) and 45 RN patients (37%); 17 of 95 planned PN (18%) were converted to RN. Tumor diameter and RENAL nephrometry scores were greater in RN patients (P <.0001 and P = .0002, respectively). Pathologic stage T3 was seen in 40% of RN patients and 10% of PN patients (P = .0002). Histologic concordance was apparent in 60 of 123 patients (49%). Median follow-up for patients alive without a recurrence was 4 years. Five-year recurrence-free survival was 98% for PN and 85% for RN. Five-year overall survival was 96% for PN and 86% for RN (P = .5). Five-year freedom from chronic kidney disease upstaging was 74% for PN and 55% for RN (P = .11). CONCLUSION: Partial nephrectomy for the treatment of unilateral, synchronous, multifocal, renal tumors with favorable characteristics was associated with a low recurrence rate. These findings suggest PN is an appropriate management strategy for this group of carefully selected patients.

Subcentimeter pulmonary nodules are not associated with disease progression in patients with renal cell carcinoma.

PURPOSE: Renal cell carcinoma most commonly metastasizes to the lung. Indeterminate pulmonary nodules develop preoperatively in half of the patients with localized renal cell carcinoma but clinical significance remains poorly defined. We determined whether the presence of indeterminate pulmonary nodules, or nodule size or number is associated with renal cell carcinoma outcomes. MATERIALS AND METHODS: We reviewed data on 1,102 patients with renal cell carcinoma in whom chest computerized tomography was done within 6 months before nephrectomy from 2002 to 2012. Patients with metastatic disease at presentation, benign tumors, pulmonary nodules greater than 2 cm or concurrent pulmonary disease were excluded, leaving 748 available for analysis. Study outcomes included lung metastasis, any distant metastasis or death from renal cell carcinoma. Cox proportional hazards models were used to assess whether the presence of indeterminate pulmonary nodules, or nodule size or number was associated with outcomes. Models were evaluated by comparing discrimination using the Harrell c-index. RESULTS: Indeterminate pulmonary nodules were present in 382 of 748 patients (51%). Median followup was 4.1 years (IQR 2.2-6.1). The presence of indeterminate pulmonary nodules was not associated with distant metastasis or death from kidney cancer. However, compared to subcm indeterminate pulmonary nodules the nodules greater than 1 cm were associated with metastatic disease after adjusting for tumor histology, stage and size (HR 2.48, 95% CI 1.08-5.68, p = 0.031). The outcome c-index increased slightly after adding nodule size to a predictive model adjusted for tumor characteristics. CONCLUSIONS: No evidence in the current study suggested that indeterminate pulmonary nodules less than 1 cm are associated with renal cell carcinoma progression, although large nodules significantly predicted metastatic disease. Patients with subcm indeterminate pulmonary nodules would be unlikely to benefit from extensive postoperative chest imaging surveillance, which should be reserved for patients with nodules greater than 1 cm.

Gene expression changes in the hypothalamus provide evidence for regionally-selective changes in IL-1 and microglial markers after acute stress.

Recent work from our laboratory and others has shown that certain stressors increase expression of the pro-inflammatory cytokine interleukin-1beta (IL-1) in the hypothalamus. The first goal of the following studies was to assess the impact of acute stress on other key inflammatory factors, including both cytokines and cell surface markers for immune-derived cells resident to the CNS in adult male Sprague Dawley rats exposed to intermittent footshock (80 shocks, 90 s variable ITI, 5 s each). While scattered changes in IL-6 and GFAP were observed in the hippocampus and cortex, we found the hypothalamus to be exquisitely sensitive to the effects of footshock. At the level of the hypothalamus, mRNA for IL-1 and CD14 were significantly increased, while at the same time CD200R mRNA was significantly decreased. A subsequent experiment demonstrated that propranolol (20mg/kg i.p.) blocked the increase in IL-1 and CD14 mRNA observed in the hypothalamus, while the decrease in CD200R was unaffected by propranolol. Interestingly, inhibition of glucocorticoid synthesis via injection of metyrapone (50mg/kg s.c.) plus aminoglutethimide (100mg/kg s.c.) increased basal IL-1 mRNA and augmented IL-1 and CD14 expression provoked by footshock. Injection of minocycline, a putative microglial inhibitor, blocked the IL-1 response to footshock, while CD14 and CD200R were unaffected. Together, these gene expression changes (i) provide compelling evidence that stress may provoke neuroinflammatory changes that extend well beyond isolated changes in a single cytokine; (ii) suggest opposing roles for classic stress-responsive factors (norepinephrine and corticosterone) in the modulation of stress-related neuroinflammation; (iii) indicate microglia within the hypothalamus may be key players in stress-related neuroinflammation; and (iv) provide a potential mechanism (increased CD14) by which acute stress primes reactivity to later immune challenge.
