The present study reports a human case of cutaneous gnathostomiasis with recurrent migratory nodule and persistent eosinophilia in China. A 52-year-old woman from Henan Province, central China, presented with recurrent migratory reddish swelling and subcutaneous nodule in the left upper arm and on the back for 3 months. Blood examination showed eosinophila (21.2%), and anti-sparganum antibodies were positive. Skin biopsy of the lesion and histopathological examinations revealed dermal infiltrates of eosinophils but did not show any parasites. Thus, the patient was first diagnosed as sparganosis; however, new migratory swellings occurred after treatment with praziquantel for 3 days. On further inquiring, she recalled having eaten undercooked eels and specific antibodies to the larvae of Gnathostoma spinigerum were detected. The patient was definitely diagnosed as cutaneous gnathostomiasis caused by Gnathostoma sp. and treated with albendazole (1,000 mg/day) for 15 days, and the subsequent papule and blister developed after the treatment. After 1 month, laboratory findings indicated a reduced eosinophil count (3.3%). At her final follow-up 18 months later, the patient had no further symptoms and anti-Gnathostoma antibodies became negative. Conclusively, the present study is the first report on a human case of cutaneous gnathostomiasis in Henan Province, China, based on the past history (eating undercooked eels), clinical manifestations (migratory subcutaneous nodule and persistent eosinophilia), and a serological finding (positive for specific anti-Gnathostoma antibodies).

A persistent left superior vena cava draining into the left atrium associated with atresia of the coronary sinus-ostium, ASD, and PDA is a rare congenital anomaly. The patient was a 4 year-old female whose complaints were frequent URI and exertional dyspnea. The congenital heart anomaly was suspected at 2 months of her age. Chest films showed cardiomegaly [C-T ratio, 75%]. EKG, Echocardiography, cardiac catheterization and angiocardiography were performed. Open heart surgery was done under impression of LV-RA shunt, bilateral superior vena cavae, and ASD. At the time of operation, huge LA and RA, inferior vena caval defect of a secundum type ASD [1.5 x 3cm in diameter], absence of innominate vein, atresia of the coronary sinus-ostium, and persistent LSVC draining into LA were noted. Direct suture closure of ASD and ligation of LSVC were done. The patient`s postoperative course was somewhat eventful: systolic murmur at apex remained. Four months after the operation, congestive heart failure attacked a few times. PDA that was overlooked at the time of open heart surgery was detected through postoperative cardiac catheterization in.4 months later. Emergent operation for closure of PDA was performed on the day of recatheterization. After that, patient`s heart failure was easily controlled without any notable problem.

A global binding agreement was adopted with the leading of United Nations Environment Program (UNEP) on May 22, 2001 in Stockholm to regulate the production and distribution on persistent organic pollutants (POPs). The agreement took effectuation with the ratification of 59 countries from the approval of 151 countries on May 17, 2004. After the approval on October 4, 2001, South Korea performed systematical investigation on POP-related substances such as chlordane, dichloro diphenyl trichloroethane (DDT), hexachlorobenzenes (HCB), heptachlor, polychlorinated biphenyls (PCBs) to get ready for the ratification of the convention with country-specific exemption. The domestic distributions of those chemical substances have been officially prohibited since the late 1960s to the early 1980s. Although there were occasional reports for the detection of some of those chemical substances, those performed minute signification in their existence in the environment. A series of investigation with documentary examination and fact-finding survey showed the possibility for the ratification on the convention without country-specific exemption.

The modified Hellers myotomy for esophageal achalasia is known as the best procedure. A properly performed transthoracic esophagomyotomy is essential to prevent complications. But it has some problems such as persistent achalasia due to inadequate myotomy, recurrence due to the healing of myotomy and reflux esophagitis due to destruction of the lower esophageal sphincter. The methods of the reoperation after esophagomyotomy for achalasia of the esophagus consist of 1 ] for persistent achalasia due to inadequate myotomy, additional myotomy feasible. 2] for esophageal reflux, a long-limb jejunal gastric drainage after vagotomy and hemigastrectomy, jejunal after conservative resection for stricture. We experienced 3 cases of reoperation after esophagomyotomy for achalasia of the esophagus. The 1st and 3rd case belongs to 30 cases which were undertaken the primary operation at the National Medical Center from 1961 to 1984. The 2nd case was undertaken the primary operation at other hospital. The 1st and 3rd case were reoperated because of persistent achalasia due to inadequate myotomy and 2rid case was caused by stricture due to reflux esophagitis. The methods of the reoperation were additional myotomy in 1st case, esophagogastrectomy and lower thoracic esophagogastrostomy in 2nd case, and esophagogastrectomy and mid-thoracic esophagogastrostomy in 3rd case. All three cases were complicated with postoperative reflux esophagitis.

Pharmaceutically active compounds (PhACs) have become an environmental havoc in last few decades with reported cases of antibiotic resistant bacteria (ARB) and antibiotic resistant genes (ARGs), lethal effects over aquatic organisms, interference in natural decomposition of organic matter, reduced diversity of microbial communities in different environmental compartments, inhibition of growth of microbes resulting in reduced rate of nutrient cycling, hormonal imbalance in exposed organisms etc. Owing to their potential towards bioaccumulation and persistent nature, these compounds have longer residence time and activity in environment. The conventional technologies of wastewater treatment have got poor efficiency towards removal/degradation of PhACs and therefore, modern techniques with efficient, cost-effective and environment-friendly operation need to be explored. Advanced oxidation processes (AOPs) like Photocatalysis, Fenton oxidation, Ozonation etc. are some of the promising, viable and sustainable options for degradation of PhACs. Although energy/chemical or both are essentially required for AOPs, these methods target complete degradation/mineralization of persistent pollutants resulting in no residual toxicity. Considering the high efficiency towards degradation, non-toxic nature, universal viability and acceptability, AOPs have become a promising option for effective treatment of chemicals with persistent nature.

Persistent current switch (PCS) system in NMR, MRI, MAGLEV and SMES has many advantages, such as uniformity and durability of magnetic field and reducing a thermal loss, which enable many superconducting application to operate effectively. This paper deals with fabrication and test of heater trigger persistent current switch using coated conductor (CC) which has high n-index, critical current independency from external magnetic field and adaptable selectivity of stabilizer. PCS system consists of magnet power supply for energizing current to a magnet, heater, switch and magnet using coated conductor tape. Finite element method (FEM) is used to simulate thermal quench (switching) characteristic and design heater trigger. With FEM simulation, optimal length of heater is calculated by temperature and time analysis. Fabrication of PCS system and test of heater trigger characteristic were performed and compared with simulation result. This paper would be the foundation of researches of superconducting switching application.

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.

Applications have evolved with the evolution of smartphones, and the search structure is changing as well. In this study, we searched through various cases of cross platform and found out the search pattern and suggested correct usage method accordingly. As a result, the search structure for cross platform can be divided into persistent navigation, temporary navigation, and auxiliary navigation. Persistent navigation is available in a hierarchical structure using springboards, lists, galleries, and top menus. Temporary navigation can take advantage of drawers, toggle menus, and pie menus, while secondary navigation can provide the same experience across platforms using an accordion menu or scrolling.

The authors applied anterior sagittal transrectal apporach (ASTRA) for the repair of urethrovaginal fistula which developed after total repair of persistent cloaca. The patient had been diagnosed to have persistent cloaca, double uterus and double vagina, and received PSARP, excision of right-side uterus and vagina, and left vaginal switch operation at 22 months old. After operation, the patient admitted several times due to frequent urinary tract infection and ectopic stone formation in bladder and neovagina. Urethro-neovaginal fistula was confirmed by cystoscopy and corrected with ASTRA. Postoperative voiding cystourethrogram showed no fistula tract. ASTRA showed improved surgical field, minimized ureterocystic damage, and preserved perirectal nerve due to limited incision of rectum.

This is a case report of successful surgical correction of coarctation of the aorta associated with the patent ductus arteriosus and the persistent left superior vena cava. The patient was a 15 year old girl and congenital heart anomaly was suspected at the sixth month after birth. Afterward there has been no embarrassing symptoms until the day of operation except slight dyspnea on exertion, The diagnosis of coarctation of the aorta and the patent ductus arteriesus detected by physical signs and X-ray studies including aortography. In the first place, coarctation of the aorta was corrected with following procedure: partial resections of the aortic wall just above and below the coarctating line of the aorta and removal of diaphragmatic structure of coarctation performed by. cross clamping aorta above and below coarctation, and then the defect of the aortic wall was closed by lateral aortorrhapic suture with atraumatic needle 3-0 silk continuously [Fig. 6]. In the second place, the patent ductus arteriosus was closed with double ligation method. The persistent left superior vena cava left as it has been, because there has been no evidence of hemodynamic abnormal shunt. After operation, excellent result was obtained; blood pressure in the upper and lower extremities was normalized and subjective complains of hypertension in the upper extremity was disappeared.
