An incidentaloma is a tumor found incidentally without clinical symptoms or suspicion; the lesion may be adrenal, pituitary, or thyroidal. We report the case of an asymptomatic individual with preoperatively undiagnosed pheochromocytoma (size: 4.86 cm) that was revealed using elective nonadrenal surgical procedures. The patient demonstrated peri- and post-operative hypertensive crisis and tachycardia. Three days after the dramatic onset of symptoms, the patient expired due to pulmonary edema, multiple organ failure, and terminal sepsis, despite administration of extracorporeal membrane oxygenation-assisted cardiopulmonary resuscitation. A left medial kidney mass obtained at autopsy confirmed pheochromocytoma.

BACKGROUND: This study aimed to retrospectively evaluate the use of sugammadex in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy. METHODS: Data were obtained from medical record review of patients who underwent VATS lobectomy from January 2013 to November 2014. Fifty patients were divided into two groups: the sugammadex group (group S, n = 19) was administered sugammadex 2 mg/kg, while the pyridostigmine group (group P, n = 31) received pyridostigmine 20 mg with glycopyrrolate 0.2 mg or atropine 0.5 mg. The primary endpoint measure was the overall incidence of postoperative pulmonary complications including prolonged air leak, pneumonia, and atelectasis. The secondary endpoint measures were the length of postoperative hospital stay and duration of chest tube insertion. RESULTS: The overall incidence of postoperative pulmonary complications in patients in group S was significantly lower compared with that of group P (5 [26.3%] vs. 17 [54.8%]; P = 0.049). Also, the durations of chest tube insertion (5.0 [4.0–7.0] vs. 7.0 [6.0–8.0] days; P = 0.014) and postoperative hospital stay (8.0 [8.0–10.0] vs. 10.0 [9.0–11.0] days; P = 0.019) were shorter in group S compared with group P. Administration of sugammadex was associated reduced with postoperative pulmonary complications (OR: 0.22; 95% CI: 0.05–0.87; P = 0.031). CONCLUSIONS: The use of sugammadex, compared with pyridostigmine, showed a significantly reduced overall incidence of postoperative pulmonary complications and decreased duration of chest tube use and postoperative hospital stay in patients undergoing VATS lobectomy, suggesting that sugammadex might be helpful in improving clinical outcomes in such patients.

Infectious coryza (IC) is an infectious disease caused by Avibacterium (Av.) paragallinarum. IC is known to cause economic losses in the poultry industry via decreased egg production in layers. Between 2012 and 2013, Av. paragallinarum was isolated from seven chicken farms by Chungbuk National University. We identified Av. paragallinarum, the causative pathogen of IC by polymerase chain reaction (PCR) and serovar serotype A, by multiplex PCR. Antibiotic sensitivity tests indicated that a few field-isolated strains showed susceptibility to erythromycin, gentamicin, lincomycin, neomycin, oxytetracycline, spectinomycin, and tylosin. A serological survey was conducted to evaluate the number of flocks that were positive for Av. paragallinarum by utilizing a HI test to determine the existence of serovar A. Serological surveys revealed high positivity rates of 86.4% in 2009, 78.9% in 2010, 70.0% in 2011, and 69.6% in 2012. We also challenged specific pathogen-free chickens with isolated domestic strains, ADL121286 and ADL121500, according to the measured efficacy of the commercial IC vaccine, PoulShot Coryza. We confirmed the effectiveness of the vaccine based on relief of clinical signs and a decreased re-isolation rate of ADL121500 strain. Our results indicate IC is currently prevalent in Korea, and that the commercial vaccine is effective at protecting against field strains.

PURPOSE: To compare the clinical and anterior segment anatomical features in primary angle closure sub-groups based on configurations of iris root insertion. METHODS: Primary angle closure patients were imaged using anterior segment optical coherence tomography. Anterior chamber depth, iris curvature, iris thickness (IT) at the scleral spur and 500, 750, and 1,500 µm from the scleral spur (IT(0), IT(500), IT(750), and IT(1500)), lens vault, iris area, angle opening distance (AOD(500)), angle recess area (ARA(750)), and trabecular iris space area (TISA(750)) were measured. Iris root insertion was categorized into a non-basal insertion group (NBG) and basal insertion group (BG). RESULTS: In total, 43 eyes of 39 participants belonged to the NBG and 89 eyes of 53 participants to the BG. The mean age of participants was greater in the NBG than the BG (62.7 ± 5.7 vs. 59.8 ± 7.3 years, p = 0.043), and the baseline intraocular pressure was higher in the BG than the NBG (16.4 ± 4.4 vs. 14.9 ± 3.3 mmHg, p = 0.037). The BG showed a greater IT(0) (0.265 ± 0.04 vs. 0.214 ± 0.03 mm, p < 0.001) and iris area (1.59 ± 0.24 vs. 1.52 ± 0.27 mm2, p = 0.045), lower ARA(750) (0.112 ± 0.08 vs. 0.154 ± 0.08 mm2, p = 0.017) and AOD(500) (0.165 ± 0.07 vs. 0.202 ± 0.08 mm, p = 0.014) compared to the NBG. CONCLUSIONS: The BG had a narrower anterior chamber angle, thicker peripheral iris, and higher pretreatment intraocular pressure.

BACKGROUND: The clinical features of spinal anesthesia may differ between young and old patients because of the anatomical and physiological changes that occur with an increase in age. This study was performed retrospectively to compare the clinical aspects of spinal anesthesia between the non-elderly and elderly patients. METHODS: We investigated the medical records of 1,180 adult patients who received spinal anesthesia during a one-year period. They were divided into two groups on the basis of 65 years of age; the non-elderly patient group (Y group, n = 813) versus the elderly patient group (E group, n = 367). Pre-, intra-, and postoperative data related to spinal anesthesia were collected. The data about satisfaction and causes of dissatisfaction with the procedure were evaluated. RESULTS: There were significant differences between the two groups in terms of age, height, and weight, except for sex. Significantly more than two attempts at spinal puncture were performed in the E group (37.6%) than in the Y group (21.4%). There were no statistically significant differences in perioperative complications after spinal anesthesia between the two groups. There were no significant differences in the reported causes of dissatisfaction between the two groups. The rate of wanting to undergo spinal anesthesia in the future was 96.4% in the Y group and 97.5% in the E group, which showed no statistically significant difference. CONCLUSIONS: Although the elderly patients had to undergo more spinal puncture attempts, more than 90% of the elderly patients were satisfied with spinal anesthesia and wanted to undergo spinal anesthesia again for similar surgeries in the future.

BACKGROUND: Emergence agitation (EA) is one of the most common complications after general anesthesia. The goal of this retrospective study was to determine the risk factors of EA in adult patients who underwent general anesthesia. METHODS: We retrospectively investigated the medical records of 5,358 adult patients who stayed in the postanesthesia care unit (PACU) of our hospital after general anesthesia during the 1-year period from January 2014 to December 2014. Psychological and behavioral status in the PACU was determined by the Aono four-point scale. Grade of 3 or 4 were considered as manifestations of EA. Multiple variables assessed EA risk factors. RESULTS: Two-hundred-forty-five patients (4.6%) developed EA. In multivariate analysis, male gender (OR = 1.626, P = 0.001), older age (OR = 1.010, P = 0.035), abdominal surgery (OR = 1.633, P = 0.002), spine surgery (OR = 1.777, P = 0.015), longer duration of anesthesia (OR = 1.002, P < 0.001), postoperative nausea and vomiting (OR = 20.164, P < 0.001) and postoperative pain (OR = 3.614, P < 0.001) were risk factors of EA. CONCLUSIONS: Male gender and older patients were risk factors of EA after general anesthesia in adult patients. Careful attention is needed for patients who receive abdominal or spine surgery, and who receive prolonged anesthesia. Adequate postoperative analgesia and antiemetic therapy should be provided to reduce the incidence of EA.

BACKGROUND: In laparoscopic surgical procedures, many clinicians recommend supraglottic airway devices as good alternatives to intubation. We compared the i-gel(R) (i-gel) and LMA Supreme(R) (Supreme Laryngeal Mask Airway, SLMA) airway devices during laparoscopic cholecystectomy regarding sealing pressure and respiratory parameters before, during, and after pneumoperitoneum. METHODS: Following Institutional Review Board approval and written informed consent, 93 patients were randomly allocated into the i-gel (n = 47) or SLMA group (n = 46). Insertion time, number of insertion attempts, and fiberoptic view of glottis were recorded. Oropharyngeal leak pressure (OLP), the use of airway manipulation, peak inspiratory pressure, lung compliance, and hemodynamic parameters were measured before, during, and after pneumoperitoneum. RESULTS: There were no significant differences between the two groups regarding demographic data, insertion time, fiberoptic view of glottis, and the use of airway manipulation. The gastric tube insertion time was longer in the i-gel group (20.4 +/- 3.9 s) than in the SLMA group (16.7 +/- 1.6 s) (P < 0.001). All devices were inserted on the first attempt, excluding one case in each group. Peak inspiratory pressure, lung compliance, and OLP changed following carbon dioxide pneumoperitoneum in each group, but there were no significant differences between the groups. CONCLUSIONS: Both the i-gel and SLMA airway devices can be comparably used in patients who undergo laparoscopic cholecystectomy, and they offer similar performance including OLP.

BACKGROUND: Hemodynamic stability can be achieved using the combination of ketamine and propofol (ketofol). This study was designed to compare the hemodynamic effects of ketofol with different ketamine-propofol ratios versus propofol after induction of general anesthesia with endotracheal intubation. METHODS: A total of 120 American Society of Anesthesiologist physical status I and II patients 20-60 years of age were randomly allocated into one of four groups. The K0 group received only 2 mg/kg propofol. The K0.15 group received 0.15 mg/kg ketamine and 1.85 mg/kg propofol. The K0.3 group received 0.3 mg/kg ketamine and 1.7 mg/kg propofol. The K0.6 group received 0.6 mg/kg ketamine and 1.4 mg/kg propofol. Endotracheal intubation was performed after muscle relaxation. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate (HR) and the bispectral index value were recorded. RESULTS: No significant differences were observed in SBP, DBP, MBP, or HR among the groups after endotracheal intubation. However, the number of patients with a decrease of MBP > 20% from baseline after induction was significantly lower in the K0.6 group compared to that in the K0 group (P < 0.05). CONCLUSIONS: The results suggest that ketofol with 0.6 mg/kg ketamine and 1.4 mg/kg propofol can be used as an alternative to 2 mg/kg propofol.

Eggs exhibiting eggshell apex abnormalities (EAA) were evaluated for changes in shell characteristics such as strength, thickness, and ultrastructure. Mycoplasma synoviae (MS) infection was confirmed by serological assay along with isolation of MS from the trachea and oviduct. Changes in eggshell quality were shown to be statistically significant (p < 0.01). We also identified ultrastructural changes in the mammillary knob layer by Scanning Electron Microscopy. While eggs may seem to be structurally sound, ultrastructural evaluation showed that affected eggs do not regain their former quality. In our knowledge, this is the first report describing the occurrence of EAA in Korea.

OBJECTIVE: To compare the treatment effects of epidural neuroplasty (NP) and transforaminal epidural steroid injection (TFESI) for the radiating pain caused by herniated lumbar disc. METHODS: Thirty-two patients diagnosed with herniated lumbar disc through magnetic resonance imaging or computed tomography were included in this study. Fourteen patients received an epidural NP and eighteen patients had a TFESI. The visual analogue scale (VAS) and functional rating index (FRI) were measured before the treatment, and at 2 weeks, 4 weeks and 8 weeks after the treatment. RESULTS: In the epidural NP group, the mean values of the VAS before the treatment, and at 2 weeks, 4 weeks and 8 weeks after the treatment were 7.00+/-1.52, 4.29+/-1.20, 2.64+/-0.93, 1.43+/-0.51 and those of FRI were 23.57+/-3.84, 16.50+/-3.48, 11.43+/-2.44, 7.00+/-2.15. In the TFESI group, the mean values of the VAS before the treatment, and at 2 weeks, 4 weeks and 8 weeks after the treatment were 7.22+/-2.05, 4.28+/-1.67, 2.56+/-1.04, 1.33+/-0.49 and those of FRI were 22.00+/-6.64, 16.22+/-5.07, 11.56+/-4.18, 8.06+/-1.89. During the follow-up period, the values of VAS and FRI within each group were significantly reduced (p<0.05) after the treatment. But there were no significant differences between the two groups statistically. CONCLUSION: Epidural NP and TFESI are equally effective treatments for the reduction of radiating pain and for improvement of function in patients with a herniated lumbar disc. We recommend that TFESI should be primarily applied to patients who need interventional spine treatment, because it is easier and more cost-effective than epidural NP.
