This study presents the development and validation of a risk assessment program of highly pathogenic avian influenza (HPAI). This program was developed by the Korean government (Animal and Plant Quarantine Agency) and a private corporation (Korea Telecom, KT), using a national database (Korean animal health integrated system, KAHIS). Our risk assessment program was developed using the multilayer perceptron method using R Language. HPAI outbreaks on 544 poultry farms (307 with H5N6, and 237 with H5N8) that had available visit records of livestock-related vehicles amongst the 812 HPAI outbreaks that were confirmed between January 2014 and June 2017 were involved in this study. After 140,000 iterations without drop-out, a model with 3 hidden layers and 10 nodes per layer, were selected. The activation function of the model was hyperbolic tangent. Precision and recall of the test gave F1 measures of 0.41, 0.68 and 0.51, respectively, at validation. The predicted risk values were higher for the “outbreak” (average ± SD, 0.20 ± 0.31) than “non-outbreak” (0.18 ± 0.30) farms ( The risk assessment model developed was employed during the epidemics of 2016/2017 (pilot version) and 2017/2018 (complementary version). This risk assessment model enhanced risk management activities by enabling preemptive control measures to prevent the spread of diseases.
2.Management of Achalasia: Expert Consensus Statements
The Korean Journal of Gastroenterology 2019;73(5):294-298
Achalasia is a motility disorder of the esophagus characterized by absence of peristalsis and failure of relaxation of lower esophagus sphincter. The introduction of high resolution manometry (HRM) and per-oral endoscopic myotomy (POEM) has made a new chapter in diagnosis and treatment of achalasia. HRM allows classify according to the subtype of achalasia, and help predict prognosis and therapeutic response. POEM is a minimally invasive, effective option for treating achalasia. The management of achalasia required tailored application of various therapies such as botox injection, pneumatic balloon dilatation, POEM, or Heller's myotomy. In this review, we state the important aspects of diagnosis as well as management of achalasia.

The importance of adopting healthy exercise routines has been repeatedly emphasized to individuals with diabetes mellitus (DM). However, knowledge about the risk of exercise-induced hypoglycemia is limited. Regular exercise reduces and delays the onset of DM-related complications particularly in individuals who already have DM. However, an excessive exercise can lead to hypoglycemia. Excessive exercise in the evening can cause hypoglycemia while sleeping. Furthermore, if individuals with DM want to have a greater amount of exercise, the exercise duration rather than intensity must be increased. In weight resistance exercises, it is beneficial to first increase the number of repetitions, followed by the number of sets and gradually the weight of resistance. When performing intermittent high-intensity training within a short time period, hypoglycemia may develop for an extended period after exercise. In addition to adjusting exercise regimens, the medication doses must be modified accordingly. Delaying exercise, adjusting the number of snacks consumed prior to exercise, reducing insulin dose before exercise, and injecting insulin into the abdomen rather than the limbs prevent exercise-induced hypoglycemia prior to a spontaneous exercise. Ultimately, with personal knowledge on how to prevent hypoglycemia, the effects of exercise can be maximized in individuals with DM, and a healthy lifestyle can prevent future complications.

OBJECTIVES: The dream recall and sleep of patients with rapid eye movement sleep behavior disorder (RBD) were not sufficiently studied. We hypothesized that RBD patients have frequent dream recall with poor sleep quality, and investigated the relationship between the dream recall frequency and sleep quality in RBD patients compared to controls. METHODS: We analyzed 81 drug naïve patients [RBD (+), 64.6±8.3 y, 57 males] and 81 age and gender matched patients with sleep disturbances without RBD [RBD (−), 63.7±7.3 y, 57 males]. All completed Pittsburgh sleep quality index (PSQI), insomnia severity index (ISI), Epworth sleepiness scale and Beck depression inventory. The 5-point rating scale was used to categorize dream recall frequency of most recent month (0=never, 4=very frequent). RESULTS: In RBD (+), dream recall frequency was much higher [frequent dreaming, 77.2% vs. 35.4%], and subjective sleep quality was much better [PSQI, 6.36±3.26 vs. 8.71±4.69]. Insomnia severity was much less in RBD (+) (ISI, 9.13±5.86) than RBD (−) (12.43±7.62). No significant differences were found in sleep parameters except lower N2 sleep % in RBD (+). The relationship between dream recall frequency and sleep was not significant in RBD (+), yet, a positive correlation was noted in RBD (−). CONCLUSIONS: RBD (+) had better sleep quality despite higher frequency of dream recall compared to RBD (−). Also dream recall was not related to their sleep quality in RBD (+), which suggests that RBD patients may have different sleep perception about their sleep and sleep quality.

PURPOSE: Insufficient production of the parathyroid hormone (PTH) by the parathyroid glands known as hypoparathyroidism, or a resistance against its action on target organs known as pseudohypoparathyroidism, cause PTH-related hypocalcemia associated with hyperphosphatemia. Signs and symptoms are caused by hypocalcemia. This study aimed to assess clinical characteristics, treatment, severity, onset time, and therapeutic responses of hypoparathyroidism and pseudohypoparathyroidism. METHODS: From January 2000 to February 2010, 21 hypoparathyroid and 10 pseudohypoparathyroid children were selected from Severance Hospital. Clinical manifestations and laboratory data were analyzed retrospectively. RESULTS: In hypoparathyroid patients, there were 14 with idiopathic hypothyroidism (66%) and 7 with 22q11.2 deletion syndrome (33%). Patients with hypoparathyroidism had more frequent neurologic symptoms compared to those with pseudohypoparathyroidism (2.89 +/- 1.75 vs. 1.25 +/- 1.67, P = 0.01). Required amounts of calcium to control hypocalcemia were larger in hypoparathyroidism than in pseudohypoparathyroidism (37.98 +/- 26.64 vs. 15.64 +/- 7.87 mg/day/kg, P = 0.034). After treatment, neurologic symptoms decreased significantly in hypoparathyroidism (P < 0.05) from 2.01 +/- 1.68 to 0.89 +/- 0.96. CONCLUSION: Hypoparathyroidism presented more severe symptoms than pseudohypoparathyroidism. Larger amounts of calcium were required to correct hypocalcemia in hypoparathyroidism than in pseudophypoparathyroidsm. These differences may be explained by the findings that distal tubules respond to PTH, in contrast to proximal tubules, in pseudohypoparathyroidism, because the GNAS gene coding is not imprinted at the distal tubular cells responsible for calcium reabsorption.

Lung isolation in a neonate can be a challenge for the anesthesiologist. We report on our anesthetic experience with a neonate who had giant bronchopulmonary sequestration (BPS). The BPS was large enough to shift the mediastinum to the contralateral hemithorax. The trachea was immediately intubated after delivery and the lungs were mechanically ventilated in the neonatal intensive care unit. To prevent desaturation during the attempt of lung isolation, a 3 Fr Fogarty catheter was inserted into the trachea alongside the endotracheal tube without extubation. A fiberscope was then passed through the blocker port of a multiport adapter instead of the bronchoscopy port to minimize leakage by tightening the Touhy-Borst valve. Hypoxemia or leakage did not occur during the procedure. For early extubation, we provided caudal analgesia with ropivacaine and morphine. The giant BPS was successfully resected and the neonate was in excellent condition for early extubation. However, reintubation was needed for the pneumothorax caused by the inadequate placement of a chest drain 9 hours after extubation.

Removal of excess cement is important to prevent biological complication in cementation of implant restoration with subgingival margin. It can be difficult to completely remove excess cement. Several techniques have been introduced to minimize excess cement using abutment replica. In this case report, a simple method for making abutment replica with hot melt adhesive material in dental office was described. This technique is simple and effective because it can be used for pre-fabricated or custom abutment without additional laboratory procedure. In addition, it can minimize excess cement after cementation of implant restoration.
