Résumé
Bilateral internal auditory canal (IAC) tumors are usually pathognomonic for vestibular schwannomas in the setting of neurofibromatosis type 2 (NF2). Descriptions of bilateral nonschwannomatous IAC tumors, such as metastasis that may mimic NF2, are limited to case reports. Here, we report a case of unusual metastatic bilateral IAC tumor originating from the ovary with a rapidly progressive pattern, which we initially suspected to be NF2.

BACKGROUND AND OBJECTIVES: Although polyvinyl acetate (Merocel®) has been widely used as a packing material after septoplasty, removable nasal packing can increase patient discomfort, local pain, and pressure. Furthermore, the removal of nasal packing has been described as the most uncomfortable and distressing feature associated with septoplasty. The purpose of this study was to investigate the efficacy of polyvinyl acetate with carboxymethyl cellulose sheet (Rhinocel®) nasal packing on patient subjective symptoms, degree of bleeding, hemostasis, and wound healing following septoplasty. SUBJECTS AND METHOD: Forty patients with nasal septum deviation requiring septoplasty were included. Following surgery, one nasal cavity was packed with Rhinocel® and the other one with Merocel®. Patient subjective symptoms while the packing was in situ, hemostatic properties, pain on removal, degree of bleeding on removal, duration of hemostasis after removal, postoperative wound healing, and the cost of the pack were evaluated. RESULTS: Although the two types of packing materials were equally effective in controlling postoperative bleeding after septoplasty, Rhinocel® was significantly more comfortable while in situ and less painful on removal than Merocel®, which was associated with significantly more bleeding on removal and so more time was needed to control hemorrhage. There was no significant difference in postoperative wound healing or pack cost. CONCLUSIONS: The use of Rhinocel® after septoplasty has less discomfort, greater patient satisfaction, and less bleeding on removal with no adverse reactions compared to Merocel® packing. Therefore, Rhinocel® may be a useful packing material after septoplasty.

BACKGROUND AND OBJECTIVES: Although many studies have assessed factors related to adherence of PAP therapy, there were no studies about factors related to doctors or device managers. The purpose of this study was to investigate the relationship between PAP therapy adherence and doctor or device manager. SUBJECTS AND METHODS: Between February 2013 and June 2015, 163 patients newly diagnosed with moderate to severe OSA in one of five hospitals were enrolled in this study. All patients received 4 weeks of PAP treatment with intervention consisting of mechanical support and motivation by doctor and device manager. Data from the PAP device were obtained following a minimum of an initial 30 days, with adherence defined as >4 h/night on 70% of nights. RESULTS: After 30 days, total adherence rate to PAP therapy was 35.6% (n=58). The adherence rate of device manager ① was 26.3% (31/118), and that of device manager ② was 60% (27/45), and there was statistically significant difference between the two device managers. Furthermore, there were statistically significant differences in the adherence to PAP therapy ranging from 85.6% to 0.0% according to doctor. CONCLUSION: Our study demonstrates that the device manager and doctor may be important factors for good adherence to PAP therapy in patients with OSA.

PURPOSE: Postoperative hypocalcemia is one of the most common complications in patients who undergo a bilateral thyroid resection and can prolong hospital stay. However, there is no reliable predictor of clinical hypocalcemia after a thyroidectomy. The aim of this study was to identify the clinical predictors of hypocalcemia after a thyroidectomy and to determine if the perioperative measurements of iPTH would be helpful in identifying patients at risk of post-thyroidectomy hypocalcemia. METHODS: 213 consecutive patients undergoing thyroidectomy between Nov 2004 and Feb 2005 were examined. The iPTH, serum calcium and ionized calcium levels were measured at 6 hours, 1 day and 2 weeks after surgery, respectively. All the patients were divided into the lower PTH group (<10 pg/ml) and normal PTH group according to the level of iPTH measured at 6 hours after surgery. RESULTS: The lower PTH group comprised 33% of all patients: 39% after the total thyroidectomy and 11% after a less than total thyroidectomy. The incidence of IV calcium replacement was 36% in the lower PTH group compared with 13% in the normal PTH group. Hypocalcemia and a lowered PTH level occurred more frequently in patients who underwent surgery for a malignant tumor than for a benign tumor. CONCLUSION: There was a correlation between the level of ionized calcium and the incidence of calcium replacement and with the 6 hr-later iPTH level. Therefore, a iPTH leveSujets)

PURPOSE: Cardiac troponin I (cTnI) is a highly sensitive and specific marker for myocardial injury, and is used to predict the outcomes in patients with acute coronary syndromes. Cardiovascular complications are the leading cause of morbidity and mortality in patients who underwent vascular surgical procedures. The aim of the study was to evaluate the association between the postoperative cTnI levels and a perioperative myocardial injury (MI) within 6 months after the vascular surgical procedures. METHODS: Eighty patients who underwent vascular surgery including an arterial bypass, amputation and a thrombectomy were included in this study. The blood samples were analyzed for cTnI immediately after surgery and 1, 2, and 3 days after surgery. RESULTS: An elevated cTnI was defined as a serum concentrations > 0.4 ng/ml in any of 4 samples. Seven patients (8.7%) had postoperative cTnI levels of > 0.4 ng/ml, which was associated with a higher risk of a postoperative cardiac event (P or =0.4 ng/ml may indicate myocardial damage after vascular surgical procedures. Therefore, the routine postoperative measurement of cTnI might be a useful predictive value of the postoperative cardiac events after vascular surgical procedures.
