Perilymphatic fistula (PLF) is a rare condition characterized by abnormal leakage of perilymph from the inner ear into the middle ear via a defect in the oval or round windows. PLF needs special attention concerning early diagnosis and treatment, because it can cause dizziness, hearing loss, tinnitus, meningitis, and other symptoms. The diagnosis of PLF usually cannot be confirmed before exploratory tympanotomy. Fascia, perichondrium, loose areolar tissue, fat and gelfoam can be used effectively in the PLF repair. Fibrin glue was used to aid in securing the graft material. However, recurrence is not rare and revision is sometimes needed to relieve the symptoms associated with the leakage of perilymph. So otologic surgeons should keep in mind that PLF has a great tendency to recur. Careful surgical procedures together with strict postoperative management are important to prevent recurrence and hydroxyapatite cement (HAC) can be used to cover the fistula area as a alternative graft material in recurrent perilymphatic fistula. We report on one recurrent case of postoperative PLF occurring at the round window that was repaired with HAC.

BACKGROUND AND OBJECTIVES: There are no data comparing clinical outcomes of complex percutaneous coronary intervention (PCI) between biodegradable polymer-biolimus-eluting stents (BP-BES) and durable polymer-everolimus-eluting stents (DP-EES). We sought to evaluate the safety and efficacy of BP-BES compared with DP-EES in patients undergoing complex PCI. METHODS: Patients enrolled in the SMART-DESK registry were stratified into 2 categories based on the complexity of PCI. Complex PCI was defined as having at least one of the following features: unprotected left main lesion, ≥2 lesions treated, total stent length >40 mm, minimal stent diameter ≤2.5 mm, or bifurcation as target lesion. The primary outcome was target lesion failure (TLF), defined as a composite of cardiac death, target vessel-related myocardial infarction (TV-MI), or target lesion revascularization (TLR) at 2 years of follow-up. RESULTS: Of 1,999 patients, 1,145 (57.3%) underwent complex PCI: 521 patients were treated with BP-BES and 624 with DP-EES. In propensity-score matching analysis (481 pairs), the risks of TLF (3.8% vs. 5.2%, adjusted hazard ratio [HR], 0.578; 95% confidence interval [CI], 0.246–1.359; p=0.209), cardiac death (2.5% vs. 2.5%, adjusted HR, 0.787; 95% CI, 0.244–2.539; p=0.689), TV-MI (0.5% vs. 0.4%, adjusted HR, 1.128; 95% CI, 0.157–8.093; p=0.905), and TLR (1.1% vs. 2.9%, adjusted HR, 0.390; 95% CI, 0.139–1.095; p=0.074) did not differ between 2 stent groups after complex PCI. CONCLUSIONS: Clinical outcomes of BP-BES were comparable to those of DP-EES at 2 years after complex PCI. Our data suggest that use of BP-BES is acceptable, even for complex PCI.

BACKGROUND: Failed or hypotensive peristalsis, two of the diagnostic criteria for NEMD, correlates with impaired anterograde propulsion and retrograde escape of esophageal contents. The aim of this study was to evaluate esophageal acid clearance (EAC) in patients with ineffective esophageal motility (IEM). METHODS: Of 252 patients performing esophageal manometry and ambulatory esophageal pH monitoring, 51 patients with normal motility and acid reflux and 40 patients with IEM and acid reflux were included. RESULTS: The amplitude of peristaltic waves in the proximal and distal esophagus and lower esophageal sphincter pressure was lower significantly in patients with IEM than those with normal motility. Percentage of time of pH<4 in total, upright, and supine period and number of reflux episodes was not different in both. Supine EAC was significantly increased in patients with IEM when compared to those with normal motility. Upright EAC was not different in both. CONCLUSION: We concluded supine EAC is increased in patients with IEM. Since IEM is frequently associated with gastroesophageal reflux disease (GERD), a more intensive therapy must be needed. We propose IEM can be as a specific entity of primary esophageal motility disorder, especially in patients with GERD.

PURPOSE: To determine predictive factors for stent failure-free survival in patients treated with a retrograde ureteral stent for a malignant ureteral obstruction. MATERIALS AND METHODS: We retrospectively reviewed 71 patients who underwent insertion of a cystoscopic ureteral stent due to a malignant ureteral obstruction between May 2004 and June 2011. Performance status, type of cancer, hydronephrosis grade, location of the obstruction, presence of bladder invasion, C-reactive protein (CRP), serum albumin, and inflammation-based prognostic score (Glasgow prognostic score, GPS) were assessed using a Cox proportional regression hazard model as predicting factors for stent failure. RESULTS: A univariate analysis indicted that hypoalbuminemia (<3.5 g/dL; hazard ratio [HR], 2.43; 95% confidence interval [CI], 1.21 to 4.86; p=0.012), elevated CRP (> or =1 mg/dL; HR, 4.79; 95% CI, 2.0 to 11.1; p=0.001), and presence of a distal ureter obstruction (HR, 3.27; 95% CI, 1.19 to 8.95; p=0.021) were associated with stent failure-free survival. A multivariate analysis revealed that the presence of a mid and lower ureteral obstruction (HR, 3.27; 95% CI, 1.19 to 8.95; p=0.007), GPS > or =1 (HR, 7.22; 95% CI, 2.89 to 18.0; p=0.001), and elevated serum creatinine before ureteral stent placement (>1.2 mg/dL; HR, 2.16; 95% CI, 1.02 to 4.57; p=0.044) were associated with stent failure-free survival. CONCLUSIONS: A mid or lower ureteral obstruction, GPS > or =1, and serum creatinine before ureteral stent insertion >1.2 mg/dL were unfavorable predictors of stent failure-free survival. These factors may help urologists predict survival time.

Extra-pulmonary neuroendocrine carcinoma is a rare and aggressive cancer. Although several biological and histological markers have been suggested as prognostic factors for this cancer, the prognostic importance of systemic inflammatory markers, including the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio, is unclear. This study aimed to evaluate the association between systemic inflammatory markers and the prognosis of extra-pulmonary neuroendocrine carcinoma. We retrospectively analyzed the clinical data of 85 patients with unresectable or metastatic extra-pulmonary neuroendocrine carcinoma who received platinum-based chemotherapy as first-line chemotherapy from August 2007 to November 2019. We used time-dependent receiver operating characteristic curve analysis to determine the cut-off values. The cut-off values for the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio were 3.0 and 158.5, respectively. There was no significant difference in the Eastern Cooperative Oncology Group performance status score, Ki-67 index, or response to chemotherapy between groups. The high neutrophil-lymphocyte ratio group showed significantly worse overall survival (high vs. low, median 11.1 vs. 21.0 months, log-rank p=0.004) and shorter median progression-free survival, but the latter was not statistically significant. The high platelet-lymphocyte ratio group also showed significantly worse progression-free survival and overall survival than the low platelet-lymphocyte ratio group (high vs. low:median 5.6 vs. 9.8 months, log-rank p=0.047 and median 13.8 vs. 21.0 months, log-rank p=0.013, respectively). In multivariable analysis, a high neutrophil-lymphocyte ratio was an independent prognostic factor for overall survival. The neutrophil-lymphocyte ratio is a potent and readily available prognostic factor for extra-pulmonary neuroendocrine carcinoma.
