The symptom of crocodile tears refers to an abnormal gusto-lacrimal reflex whereby any stimulus causing parotid secretion also induces lacrimation. It is a sequelae lesion of facial nerve, usually after the facial paralysis. The authors found the symptom of crocodile tears in one case after facial paralysis due to herpes zoster oticus and two cases after Bell's palsy.

PURPOSE: The aim of this study is evaluating the accuracy of preoperative magnetic resonance imaging (MRI) in patients who underwent pelvic lymph node dissection (PLND). MATERIALS AND METHODS: The medical records of 1,528 patients who underwent radical prostatectomy and PLND from 2003 to 2017 in Seoul National University Bundang Hospital were retrospectively reviewed. We evaluated the various clinicopathologic variables including preoperative MRI findings and pathologic lymph node (LN) metastasis. The prediction model for pathologic LN metastasis was assessed using univariate and multivariable logistic regression analyses and areas under receiver operating characteristic (ROC) curves. RESULTS: The mean age of our cohort was 66.4±6.7 years. Positive LN finding of preoperative MRI finding was observed in 9.4% (145 of 1,528) of patients. 5.3% (81 of 1,528) of patients had confirmed final pathologic LN metastases. Sensitivity and specificity of preoperative MRI were 30.8% and 91.7%, respectively. Multivariable analysis showed that preoperative MRI findings, clinical stage and biopsy Gleason score were independent significant predictors for pathologic LN metastasis (p < 0.001, p=0.002, and p < 0.001, respectively). Prediction model using preoperative MRI findings and National Comprehensive Control Network risk stratification showed fair accuracy using ROC analysis. CONCLUSIONS: Preoperative MRI findings for pathologic LN metastasis showed limited prediction value. A large-scale, multicenter, prospective study is needed to fully evaluate the clinical significance of preoperative MRI.

A 68 year-old man visited our institution due to chest pain. Coronary angiography revealed triple vessel disease. A computed tomographic angiogram performed as a routine preoperative examination demonstrated an intraluminal spider-web-like mass from the infrarenal abdominal aorta to both common iliac arteries. The infrarenal aorta and both common iliac arteries were excised and replaced with concomitant off-pump coronary artery bypass grafts. Histologic examination of the aorta suggested an intimal sarcoma. A postoperative computed tomographic angiogram performed 3 months postoperatively showed no evidence of a residual or a recurred lesion.

BACKGROUND: We evaluated mid-term results of mitral annuloplasty using a flexible band and a completely rigid ring for mitral valve repair in patients with degenerative mitral regurgitation (MR). MATERIAL AND METHOD: From January 2004 to September 2008, 71 patients (M:F=36:35, 55+/-13 years) underwent mitral valve repair with mitral annuloplasty for degenerative MR. Ring annuloplasty was done using a Cosgrove-Edwards flexible band (Group I, n=43) or a Carpentier-Edwards classic ring (Group II, n=28). There were no differences in preoperative characteristics of the participants. Average duration of follow-up was 36 months (range: 2~69 mos). RESULT: There was no in-hospital mortality. Postoperative morbidity, which included atrial fibrillation (n=7) and low cardiac output syndrome (n=5) in groups I and II were similar. There was one late death in group II. The proportion exhibiting freedom from recurrent mitral regurgitation (> or =moderate) at 4 years in Groups I and II were, respectively, 94.5 and 91.8%, (p=0.695). Left ventricular ejection fraction decreased in the early postoperative period (7+/-2 days) and recovered by last follow-up (25+/-16 mos; p=0.002). The pattern was similar in groups I and II (p=0.905). Re-operation was performed in 3 patients (1 in Group I and 2 in Group II, p=0.316). Four-year event-free survival (free of adverse valve-related events) was 95.2% for Group I and 92.6% for Group II; this difference was not significant, p=0.646). CONCLUSION: The type of technique used in mitral annuloplasty to repair the mitral valve repair after degenerative MR did not affect mid-term clinical and functional results.

Acute airway obstruction during endotracheal intubation status is embarrassing and critical situation which requires early diagnosis and immediate management. Endotracheal tube obstruction with foreign body is rare but a variety of objects have been reported. We present a case of endotracheal tube obstruction as a result of previous aspirated foreign body that moved from the bronchial tree into the endobroncheal tube.

PURPOSE: The aim of this study was to analyze the outcomes of immediate primary repair (IPR) compared with delayed repair (DR) after initial suprapubic cystostomy. MATERIALS AND METHODS: We reviewed the records of 60 patients with bulbous urethral disruption after blunt trauma from February 2001 to March 2011. Seventeen patients who presented in an acute injury state underwent IPR; 43 patients underwent DR after the initial suprapubic cystostomy. None of the patients had undergone previous urethral manipulation. We compared the outcomes, including stricture, impotence, and incontinence, between the two management approaches. We also measured the time to spontaneous voiding, the duration of suprapubic diversion, and the number of days spent in the hospital. RESULTS: The median follow-up was 20.5 months (range, 13 to 59 months; mean, 23.3 months). Among 17 patients in the IPR group, strictures developed in 2 patients (11.7%), and among 53 patients in the DR group, strictures developed in 8 patients (18.6%, p=0.709). The incidences of impotence and incontinence were similar in both groups (17.6% and 0% in the IPR group vs. 27.9% and 4.6% in the DR group, p=0.520 and 1.000, respectively). The time to spontaneous voiding and the duration of suprapubic diversion were significantly shorter in the IPR group (average 27.3 and 33.4 days, respectively) than in the DR group (average 191.6 and 198.1 days, respectively; p<0.001 and <0.001). CONCLUSIONS: IPR may provide comparable outcomes to DR and allow for shorter times to spontaneous voiding and reduce the duration of suprapubic diversion.

Lidocaine is a commonly used local anesthetic for dental treatment. Urticaria caused by lidocaine has seldom been reported. Generally, urticaria immediately develops after exposure to a causative agent and is considered a manifestation of IgE-mediated hypersensitivity. However, delayed urticaria caused by local anesthetics was reported to be related to cell mediated hypersenstivity. A 3-year old girl visited our allergy clinic due to delayed urticaria after local administration of lidocaine. Both skin prick and intradermal tests with lidocaine revealed negative reactions. However, the provocation test with subcutaneous injection of lidocaine showed urticaria 7 hours after test. In order to identify alternative local anesthetic for the subsequent dental procedure, we performed skin prick, intradermal and provocation tests with procaine, a local anesthetic of the other class, all of which showed negative results. Therefore, we recommended procaine as an alternative local anesthetic, and the patient was successfully treated with procaine. To the best of our knowledge, this is the first case of delayed urticaria caused by lidocaine in Korea.

Purpose: Sixty to eighty percent of children with egg allergy are able to tolerate eggs in baked form. The purpose of this study was to evaluate the clinical usefulness and diagnostic value of measurements of IgE specific to egg white, ovalbumin, and ovomucoid for reactivity to baked egg in children with sensitivity to egg. Methods: Two hundred seventeen children with suspected egg allergy underwent open food challenges with baked egg (in the form of muffins). The outcomes of the challenges were compared to the serum concentrations of IgE specific to egg white, ovalbumin, and ovomucoid by using ImmunoCAP. Results: There were no statistically significant differences in levels of IgE specific to egg white, ovalbumin, and ovomucoid between the baked egg challenge positive and negative groups younger than 2 years (n = 163). However, significant differences were observed between the challenge positive and negative groups in 54 subjects aged 2 to 5 years (all P < 0.05). The optimal cutoff points of egg white, ovalbumin, and ovomucoid specific IgE levels among children aged 2 to 5 years were 12.40 kU A/L (sensitivity 79%, specificity 66%), 4.07 kU A/L (sensitivity 88%, specificity 58%), and 3.65 kU A/L (sensitivity 77%, specificity 62%), respectively. Conclusion The level of IgE specific to egg white and its components can predict the reactivity to baked egg in children aged 2 to 5years.
