Abstract
Objectives: This study investigated the clinical features of patients with complete resection of thymic carcinoma. Patients and Methods: The clinical records from 11 patients who underwent a complete resection of thymic carcinoma were retrospectively reviewed. Results: Twelve of 22 patients underwent a resection (a complete resection in 11 and an incomplete in 1). Six of the 11 patients with complete had confirmed recurrent tumors. The 5-year survival rate was 45.4%, and the median survival time was 50.6 months. The patients who underwent complete resection showed significantly better prognosis than cases with incomplete resection and inoperable cases ( p = 0.048). Three of the 6 patients had a recurrence within 1 year. Frequent sites of recurrence were the pleura, pericardium, and lung. Conclusions: A complete resection improved the prognosis of thymic carcinoma. Further prospective studies regarding postoperative adjuvant therapy are necessary to prevent local recurrence after a surgical resection for thymic carcinoma.

Abstract
The aim of the present study was to clarify the involvement of protein kinase Cγ (PKCγ) in the facial neuropathic pain following infraorbital nerve injury. We analyzed the change in PKCγ expression in the trigeminal spinal subnucleus caudalis (Vc) and upper cervical spinal cord (C1/C2) following chronic constriction injury of the infraorbital nerve (ION-CCI). We also studied ION-CCI-mediated mechanical nocifensive behavior in rats. The mechanical head-withdrawal threshold significantly decreased 1 to 14 days after ION-CCI compared with that before ION-CCI and in sham rats. The expression of PKCγ was significantly larger in the ipsilateral Vc compared with the contralateral side in ION-CCI rats 3, 7, and 14 days after ION-CCI. Intrathecal (i.t.) administration of the PKCγ inhibitor chelerythrine prevented an increase in the PKCγ expression in the ipsilateral Vc. Moreover, i.t. administration of chelerythrine annulled ION-CCI-mediated reduction in the head-withdrawal threshold. Taken together, these findings suggest that PKCγ expression in the Vc played an important role in the mechanism of orofacial static mechanical allodynia following trigeminal nerve injury.

Abstract
404 Background: Treatment options for metastatic renal cell carcinoma (mRCC) have increased. Complete remission is, however, rarely seen and patients are treated with multiple sequential therapies. We assessed clinical activity of sorafenib rechallenge after progressing on other therapies. Methods: Patients with mRCC who received a second course of sorafenib therapy after failure of prior sorafenib and other agents were retrospectively identified. RECIST-defined objective response rate and progression-free survival (PFS) and toxicity were analyzed. Results: Fourteen patients with mRCC who were retreated with sorafenib were identified and twelve patients were assessable for this study. 92% were male. Median age at first systemic therapy was 63 years. Prior nephrectomy was performed in 92% of patients. 42% of patients had favorable or intermediate risk, 17% poor, and the rest not available per MSKCC criteria. Eighty-three percent of patients were treated with other agents before initial sorafenib therapy, including 75% interferon-alpha (IFN-alpha), 50% interleukin-2 (IL-2), and 17% sunitinib. First sorafenib therapy began a median of 9.0 months after the diagnosis of mRCC and produced a clinical benefit (PR + SD) rate of 75% and a median PFS of 5.0 months. 67% of patients discontinued initial sorafenib for disease progression and 33% for adverse events. Interval between discontinuation of initial sorafenib and rechallenge was a median of 7.6 months. During the intervening period, 50% of patients were treated with sunitinib, 33% with everolimus, 25% with VEGFR1 vaccine, and others. Clinical benefit rate of 67% and a median PFS of 4.3 months were obtained on sorafenib rechallenge. There was no significant difference in outcome to sorafenib rechallenge based on duration between sorafenib treatments or number or type of intervening treatments. No new severe toxicity was observed during rechallenge. Conclusions: Sorafenib rechallenge has potential to achieve clinical benefits, is well-tolerated, and may be considered after multiple sequential therapies in select mRCC patients. No significant financial relationships to disclose.

Abstract
OBJECTIVES Various forms of adrenocortical insufficiency can cause musculoskeletal symptoms such as muscle pain, tautness of the limbs, arthralgia, and flexion contractures. However, the findings of neurological investigations are inconclusive and have not been well summarized. METHODS We report the case of a 61-year-old man with isolated adrenocorticotropic hormone deficiency who presented with musculoskeletal symptoms, including flexion contractures. We performed three neurological investigations: nerve conduction studies, electromyography, and muscle biopsy analysis. Further, we reviewed reports of 16 patients with various forms of adrenocortical insufficiency and musculoskeletal symptoms by considering the findings of these three investigations. RESULTS From the literature review, we found that (a) analysis of muscle biopsy is the most sensitive technique, followed by electromyography and then nerve conduction studies; and (b) the longer the duration of the musculoskeletal symptoms, the greater the incidence of abnormal findings with all three techniques. CONCLUSIONS Physicians may prioritize neurological investigations, depending on these findings.

Abstract
Descending necrotizing mediastinitis (DNM) originating from deep cervical infection is a rare and serious clinical condition with a high mortality rate. Clinical feature of 5 patients undergone surgical drainage for DNM, between 2006 and 2009 were assessed. There were 3 male and 2 female patients whose age ranged from 57 to 83 years old (mean 69.8). All 5 patients had no underlying disease except for 1 patient with severe dental caries. The primary infections of these patients were tonsillitis and pharyngitis. The mean duration from onset of symptom to the referral to our hospital was 14 days (ranged 2 to approximately 41). Two patients underwent cervical drainage for upper mediastinum, and 3 patients were required mediastinal drainage by thoracotomy. There was no post-operative death. Early and aggressive surgical drainage of the neck and mediastinum by a multidisciplinary team of surgeons is very important in the treatment of DNM.

Abstract
Mutations in the uromodulin gene cause the autosomal disorders familial juvenile hyperuricemic nephropathy (FJHN) and medullary cystic kidney disease type 2 (MCKD2). However, methods to detect the mutant form of the uromodulin protein have not been developed. In this study, we developed a liquid chromatography-mass spectrometry (LC-MS) method for detection of the mutated uromodulin peptide (C148W). Our method can distinguish the mutant peptide, GWHWE, from wildtype peptide, GWHC*E. Using MS/MS analysis with a selected reaction monitoring (SRM) mode, peptide-specific fragment ions (m/z 714 --> 381, 471, 567, and 679 for GWHWE and m/z 688 --> 381, 445, 541, and 653 for GWHC*E) were detected.

Abstract
Purine is a general term for purine nucleotides, nucleosides, bases, and nucleic acid. The amount of purine nucleotides, nucleosides, and bases in purine-rich cauliflower was determined with the use of LC-MS and HPLC, and the ratio of these molecules were compared with in raw and in heated condition. Total purine content of raw and heated cauliflower was 42.6 and 43.2 mg/100 g, respectively. Nucleotide content was increased from 0.02 to 50.8 micromol/100 g, and nucleoside content was decreased from 12.4 to 7.7 micromol/100 g, by heating.

Abstract
Marine recreational beaches are monitored for fecal contamination by Enterococcus spp. (ENT) counts. Although different ENT species in the environment tend to thrive in and originate from distinct hosts, the current monitoring method does not differentiate among species. Time-consuming isolation-based species identification precludes routine analysis of environmental ENT communities. Therefore, an isolation-independent DNA fingerprinting method was developed to characterize environmental ENT communities using DNA length polymorphism of the spacer region between the groES and groEL genes common to most ENT species. Capillary electrophoresis resulted in distinct peak sizes of PCR products that carried polymorphic groESL spacers (300-335 bp in length) among 8 different ENT species (Enterococcus avium, Enterococcus gallinarum, Enterococcus casseliflavus, Enterococcus mundtii, Enterococcus hirae, Enterococcus faecium, Enterococcus durans, and Enterococcus faecalis). Distortions in true species ratios observed in electropherograms were caused by PCR biases arising in a mixed ENT community DNA template. E. faecalis was overestimated and E. avium and E. faecium were underestimated compared to the original species ratios in the mixed community. The PCR product bias was constant between species, so good approximation of the species ratio in ENT communities is possible. In environmental samples, a high percentage of E. faecalis (96%) together with high total ENT counts were observed in samples collected from a sewer line and from several sites in a storm drain system where sewage leaks were suspected. In contrast, samples with <400 CFU 100 ml-1 ENT were either dominated by E. mundtii or had 4 or more ENT species. The latter ENT community profiles are considered to be signatures of enterococci rarely associated with animals with low or of non-fecal origin.

Abstract
Symptom management in palliative care requires reliable symptom assessment. We assessed the inter-rater reliability of a simple proxy symptom-assessment scale using the Japanese version of the Support Team Assessment Schedule (STAS-J) in a hospital-based palliative care team (HPCT) setting. By doing this, we assessed symptoms in a series of consecutive patients at two university hospitals with certified HPCTs within 2 days of referral and 7 days after. A physician and nurse assessed 20 symptoms. In total, 120 patients were assessed within 2 days of referral and 92 patients at 7 days after referral. As a result, we find that the intra-class correlation coefficients were 0.02-0.89 at referral and 0.20-0.92 at 7 days after. The perfect concordance rates were 37-89% at referral and 53-96% at 7 days after. The perfect or +/-1 concordance rates were 71-97% at referral and 73-100% at 7 days after. In conclusion, the symptom item of the STAS-J had high inter-rater reliability.

Abstract
e16514 Background: We reported mitochondrial (MT) scoring system related to platinum response in ovarian cancer (OC) (Oncol Rep2008). We investigated whether the system could be useful to evaluate cellular drug sensitivity and patients’ prognosis. Methods: Ultrathin sections of surgical specimens prepared from 41 OC patients were examined by electron microscopy. Ovarian carcinoma cell line 2008 and its platinum- or taxane-resistant variant C13 or PX24 were used as control cells. Seven independent MT features including diameter and pattern of cresta structure were examined. Clinical response and in vitro sensitivity to platinum (P), taxane (T), irrinotecan (CPT), and doxorubicine (D) were examined while the MT scoring was performed independently. Results: Of 41 cases, 37 were available for clinical evaluation (stage II-IV, received 6 cycles of TP chemotherapy). Fifteen cases were responsive, while 22 were resistant. Total MT score in 15 responsive cases was 5.13 ± 1.13 (M ± SE) and was 11.41 ± 0.43 in 22 resistant cases (p < 0.001). Receptor operative characteristics (ROC) analysis revealed that resistant total “cut-off” score was ≥ 10 points (p < 0.05; AUC = 0.86). Except for D, the scoring system well related to P, T, and CPT sensitivity (p; <0.001, <0.001, 0.006). ROC analysis revealed resistant “cut-off” score for P, T and CPT were ≥ 11, 5, and 10 points (p < 0.05; AUC > 0.80). With a median follow up of 20 months, 11 patients have relapsed. The progression-free survival (PFS) curves show a difference in favor of low scoring group of patients (N = 14) compared to high scoring group (N = 19) (hazard ratio 3.99, p = 0.045), corresponding to an absolute difference in 6-months PFS 16% (89 vs 73%). Conclusions: This MT scoring system excellently related to clinically diagnosed P sensitivity as well as cellular sensitivity to P, T and CPT. Each drug has its own specific “cut-off” score, suggesting that the MT function might be differentially involved in drug sensitivity. No significant financial relationships to disclose.
