Diffuse alveolar hemorrhage (DAH) is an uncommon complication in patients with systemic lupus erythematosus (SLE), and mortality remains high. In recent years, cases of DAH due to SLE treated with extracorporeal membrane oxygenation (ECMO) have rarely been reported. The authors present a case of a 43-year-old woman with SLE who had rapidly aggravating dyspnea and hemoptysis. She was diagnosed as having DAH with refractory respiratory failure and was successfully managed with veno-venous ECMO. We propose ECMO as a useful salvage therapy in patients with alveolar hemorrhage secondary to SLE who are failing conventional ventilatory support.

Adenoid cystic carcinoma is a rare disease of which incidence is 10-15 % of bartholins gland carcinoma. The clinical presentation is characterized by a vulval mass that existed for a prolonged period to the onset of symptoms, usually infection, pain, and burningsensation Histologically, this tumor is characterized by cribriform pattern cell growing and perineural invasion. The obtaining of clear surgical margins is the most important aspect of treatment. Here we report a case of adenoid cystic carcinoma of the Bartholins gland with a brief review of literature.

Primary chondrosarcoma of the extraskeletal soft tissue is extremely rare. Extraskeletal chondrosarcoma was first described as entity in 1953 by Stout and Verner, who were able to collect a series of seven cases. Because of the rarity of this lesion in extremities, neither the clinical course nor the preferred method of treatment has been clearly established. Authors report a case of extraskeletal chondrosarcoma which occurred on the right forearm of a thirty-nine-year-old man. The lesion was completely excised with free resection margins. There was no recurrence or metastasis for four years follow up.

OBJECTIVES: The primary objective of this study is to compare model performance of machine learning methods with that of a previous study in which a nonlinear mixed effects model was created using NONMEM(R) for the pharmacokinetic and pharmacodynamic data for propofol. The secondary objective was to evaluate if a pharmacodynamic model describing the relationship between the dose of propofol and bispectral index (BIS) outperform that describing the relationship between a pharmacokinetic model derived-predicted concentrations of propofol and BIS. METHODS: Data were collected during a study involving the infusion of propofol into healthy volunteers. Pharmacokinetic and pharmacodynamic models were constructed using artificial neural networks (ANNs), support vector machines (SVMs), and multi-method ensembles and were compared with the nonlinear mixed effects method as implemented by NONMEM(R). Model performance was assessed by goodness-of-fit statistics, paired t-tests between predicted and observed values for each model and scatterplots. RESULTS: In pharmacokinetic analysis, ensemble I, the mean of ANN and NONMEM(R) predictions, achieved minimal error and the highest correlation coefficient. SVM produced the highest error and the lowest correlation coefficient. In pharmacodynamic analysis, ANN exhibited the best performance. An ANNModel describing the relationship between the dose of propofol and BIS was not inferior to an ANN model describing the relationship between predicted concentrations of propofol derived from an ANN pharmacokinetic model and BIS. CONCLUSIONS: In pharmacokinetic analysis, ensemble combined with ANN achieved slightly better performance than NONMEM(R). The relationship between the dose of propofol and BIS can be predicted without considering pharmacokinetics of propofol.

Performance of facial aesthetic surgeries except rhinoplasty in otorlarygoloic department is not usual in South Korea. However, otolaryngologic doctors have been performing facial surgeries, thus, their knowledge of facial surgical anatomy is better than that of other doctors. For this reason, otolaryngologic doctors should study hard in order to learn about performance of facial aesthetic surgeries. Recently, in South Korea, because many facial aesthetic surgeries have been performed, many complications have been reported and facial aesthetic surgery techniques have been developed rapidly. Herein, I would like to introduce some facial aesthetic and reconstructive techniques that are not usually performed in the otolaryngologic department in South Korea.

Klinefelter's syndrome (KFS) is a gonosomal aberration disease that occurs in males, and is characterized by 47, XXY karyotype, hypogonadism and a lack of secondary sexual characteristics. A potential link between this hormonally deficient syndrome and autoimmune disease, particularly systemic lupus erythematosus (SLE), has been reported. On the other hand, KFS is rarely reported to be accompanied by rheumatoid arthritis (RA), and there are no Korean cases reported. We report the first Korean case of a KFS patient with sero-positive RA and discuss the role of the pathogenesis of RA with KFS.

Infectious mononucleosis, a common systemic illness primarily involving children and young adults, is due apparently to the Epstein-Barr virus (EBV). Although neurologic complications of infectious mononucleosis are rare, these include meningoencephalitis, Guillain-Barre syndrome and mononeuritis, and facial nerve paralysis. Bilateral facial nerve palsy rarely develops in patients with a primary Ebstein-Barr virus (EBV) infection, and only a few of these have clinical manifestations of infectious mononucleosis. We report a case of a 18-year-old man with bilateral facial nerve paralysis associated with infectious mononucleosis.
