Swine influenza is an acute respiratory disease prevalent in pig-growing areas worldwide. In total, 518 gilt and sow serum samples and 14 litters (66 samples) of aborted fetuses from 37 farms (average of 14 serum samples per farm) in Gyeongbuk Province were collected between September 2010 and May 2011. All samples were examined for antibodies to swine influenza virus (SIV) H1N1 and H3N2 using enzyme-linked immunosorbent assay (ELISA). The seropositive rates of gilt and sows were 59.8% (310/518) for SIV H1N1, 78.8% (408/518) for H3N2, and 55.6% (288/518) for both subtypes tested. The rate of aborted fetuses was 13.6% (9/66) for H1N1, 9.1% (6/66) for H3N2, and 9.1% for both subtypes. The seroprevalence for H1N1 in gilts and sows was 46.6% (69/148) and 65.1% (241/370), respectively, and that for H3N2 was 78.4% (116/148) and 78.9% (292/370), respectively.

Unilateral absence of a pulmonary artery (UAPA) is a rare congenital anomaly that may present with various symptoms, depending on the nature and severity of other cardiovascular anomalies. Furthermore, contralateral lung surgery in patients with UAPA is extremely rare, and clinical experience is limited. This report describes a case of surgical treatment of contralateral primary lung cancer in a patient with isolated UAPA. A 56-year-old man was diagnosed with primary lung cancer accompanied by isolated UAPA on the contralateral side. He underwent meticulous cardiorespiratory function tests preoperatively. We performed a right lower lobectomy. Although in the immediate postoperative period, the patient suffered from a mild decline in his respiratory function, he recovered uneventfully. The present case shows that preoperative awareness of UAPA and meticulous perioperative management enable contralateral lung surgery to be performed safely.

Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) characterized by severe hypoglycemia caused by inappropriate over secretion of insulin is the most common cause of hypoglycemia in early infancy. The symptoms of hypoglycemia in neonate and infancy are neonatal sepsis, respiratory difficulty, tachypnea, apnea, cyanosis, and seizure. Especially the recurrent and severe hypoglycemia within $1^{st}$ year of life is responsible for severe and irreversible brain damage. To prevent it aggressive treatment is required. Due to severe and irreversible brain damage these children frequently require anesthesia during imaging procedures such as MRI or during various dental surgical procedures. Because of frequent hypoglycemia and dental phobia in children with neurologic disorder, anesthesiologists should pay attention to patient. We report a successful anesthetic management in a patient with PHHI for dental procedures.

Allergic diseases such as asthma, allergic rhinitis, atopic dermatitis, and food allergy, are most common chronic, noncommunicable diseases in childhood. In the past few decades, the prevalence has increased abruptly worldwide. There are 2 possible explanations for the rising prevalence of allergic diseases worldwide, that an increased disease-awareness of physician, patient, or caregivers, and an abrupt exposure to unknown hazards. Unfortunately, the underlying mechanisms remain largely unknown. Despite the continuing efforts worldwide, the etiologies and rising prevalence remain unclear. Thus, it is important to identify and control risk factors in the susceptible individual for the best prevention and management. Genetic susceptibility or environments may be a potential background for the development of allergic disease, however they alone cannot explain the rising prevalence worldwide. There is growing evidence that epigenetic change depends on the gene, environment, and their interactions, may induce a long-lasting altered gene expression and the consequent development of allergic diseases. In epigenetic mechanisms, environmental tobacco smoke (ETS) exposure during critical period (i.e., during pregnancy and early life) are considered as a potential cause of the development of childhood allergic diseases. However, the causal relationship is still unclear. This review aimed to highlight the impact of ETS exposure during the perinatal period on the development of childhood allergic diseases and to propose a future research direction.

Although the rare earth elements (REEs) recycling industry is expected to increase worldwide in hightech industry, regulations for worker safety have yet to be established. This study was conducted to understand the potential hazard/risk of REE recycling and to support the establishment of regulations or standards. We review the extensive literature on the toxicology, occupational safety, and health issues, and epidemiological surveys related to the REEs, and propose suitable management measures. REE recycling has four key steps such as collection, dismantling, separation, and processing. In these processes, hazardous substances, such as REEs-containing dust, metals, and chemicals, were used or occurred, including the risk of ignition and explosion, and the workers can be easily exposed to them. In addition, skin irritation and toxicities for respiratory, nervous, and cardiovascular systems with the liver toxicity were reported; however, more supplementary data are needed, owing to incompleteness. Therefore, monitoring systems concerning health, environmental impacts, and safety need to be established, based on additional research studies. It is also necessary to develop innovative and environment-friendly recycling technologies, analytical methods, and biomarkers with government support. Through these efforts, the occupational safety and health status will be improved, along with the establishment of advanced REE recycling industry.

Empyema with bronchopleural fistula is an uncommon, but serious problem. Early diagnosis and adequate drainage of the empyema cavity are well established principles for the initial management of this condition and will enable patient to recover from the toxic effects of loculated pus. 37 patients of empyema with bronchopleural fistula were treated at the department of the chonbuk National University Hospital between 1981 and 1988. The age group of fifty and sixty decades occupied 64.8%. Bacteriologic cultures of the pus were postive in 56.8%. The most common organism of the culture was staphylococci(42.9%). And the others were Pseudomonas(19%). Klebsiella(14.3%), and E. doli. No growth of pathologic organism was reported 43.2%. 24 patients of empyema with bronchopleural fistula were nonoperative causes : There were 10 pulmonary tuberculosis, 3 abscess, 9 ascending infection, one bronchiectasis and one tumor, respectively. The remaining 13 were occurred as postoperative complications ; pneumonectomy in 6, lobectomy in 4, decortication in 2, and lobectomy with segmentectomy in 1. When used as the initial mode of drainage, closed thoracostomy was performed to almost all of the patients, but 4 patients were died during this treatment. Main operations were performed except 4 died patients ; open thoracostomy in 21, open thoracostomy with myoplasty in 3, decortication in 5, decortication with resection in 3, and completion pneumonectomy in 1. Open thoracostomy was performed in 21 patients which results were favorable except one death. Permanent open thoracostomy is an old but still useful minor operation in patients with empyema with bronchopleural fistula. The overall mortality rate was 15% (6 patients) and the causes of the death were respiratory insufficiency or sepsis, or both.

Optimal management of indoor air quality in a confined pig house, especially in winter, is indispensable for preventing infectious respiratory disease to workers and animals. This study was performed to elucidate the correlation of aerial contaminants and climate factors in a confinement. It was observed that indoor air contaminants ion in the confinement was the highest at 2:00-5:00 pm in a day, followed by 8:00-11:00 pm and 8:00-11:00 am. This was attributed to the increase of pig activities in the afternoon. The concentration of total dust and total airborne bacteria was found to have a significant correlation with temperature and relative humidity (p<0.05). Correlation of total dust and total airborne bacteria, total dust and ammonia, and total dust and odor were shown statistically significant at 95% confidence level. In conclusion, temperature and total dust concentration correlated significantly with all the parameters except for hydrogen sulfide ($H_2S$). This could be explained by the fact the dryness of pig feces by increase of interior temperature and resuspension of feed deposited on the floor by the pig activity, resulted in high generation of dust which adsorbed and carried the airborne bacteria and odor compounds in a confined pig house. It was proved that the adsorptive capacity of dust with ammonia ($NH_3$) was higher than that with hydrogen sulfide ($H_2S$).
