PURPOSE: Reports of clinical findings and treatment for pediatric urinary stone have been published relatively infrequently. Extracorporeal shock-wave lithotripsy (SWL) is a minimally invasive method of treating urinary stone and has been shown to be effective in the pediatric population. We evaluated the clinical characteristics of patients with pediatric urinary stone and compared the therapeutic results of two SWLs, LT-01+ and Modulith SLX lithotriptors. MATERIALS AND METHODS: The records of 57 children treated by SWL were analyzed retrospectively. Twenty-five patients were treated by LT-01+ (group I) and 32 by Modulith SLX (group II) lithotriptor. The outcomes, including the number of treatment sessions, stone free rate and complications, were assessed. RESULTS: The average age of all 57 children, 36 male and 21 female, was 14.3 years. Chief complaints were flank pain (71.9%), gross hematuria (10.5%) and urinary tract infection (12.3%). The average stone size was 8.2mm (2-15mm). The success rates of each SWL were similar in both groups (group I: 88.0%, group II: 90.6%). However the average number of treatment sessions/patient in Group I was significantly smaller than that of Group II (group I: 2.92, group II: 1.35, p<0.05). Flank pain and gross hematuria were developed similarly after treatment in both groups, and needed only conservative therapy and was resolved within three days. CONCLUSIONS: Clinical characteristics of urinary stone in children were similar to those of adults. There was no significant difference in treatment success rate between the two types of lithotriptors but the number of treatment sessions was smaller in patients treated by Modulith SLX lithotriptor.

PURPOSE: The purpose of this study was to identify international students' use of university health centers by individual characteristics and seasons. METHODS: This was a retrospective descriptive study using data obtained from the electronic record system of one university health center. The study participants were international undergraduate students who registered for any of two semesters between March 1, 2014 and February 28, 2015 and visited the university health center during their registration period. RESULTS: The most common reasons for visits were problems of head, eye, nose and throat systems, followed by respiratory system. Their visits mostly occurred in the fall and spring. The most frequently used services were distribution of oral medication followed by wound treatment. The number of visits per individual was statistically different by gender (u=-3.307, p=.001), but not by their major (chi2=.543, p=0.762) or nationality (chi2=5.518, p=.271). CONCLUSION: Further study is necessary to better define health needs and related factors for this unique population. The electronic record system provides great opportunities in development and application of need based health services for international students and for research in this area.

Sparganosis usually means the plerocercoid larval infection of Spirometra species. It is endemic mainly in countries where the habit of eating raw snake or frog, or the habit of poulticing with snake skin exists. The most common endemic area is Korea, Japan and China, and the most common localizations are subcutaneous connective tissue and superficial muscles. We experienced a case of scrotal sparganosis in a 32-year-old man presenting with painless hard masses in left scrotum. He underwent by serum Enzyme Linked Immunosorbent Assay (ELISA) and was treated by surgical excision.

Diffuse refractory vascular spasms associated with coronary bypass artery grafting (CABG) are rare but devastating. A 42-year-old male patient with a past history of stent insertion was referred for the surgical treatment of a recurrent left main coronary artery disease. A hemodynamic derangement developed during graft harvesting, necessitating a hurried initiation of cardiopulmonary bypass (CPB). Although CABG was carried out as planned, the patient could not be weaned from the bypass. An emergency coronary angiography demonstrated a diffuse spasm of both native coronary arteries and grafts. CPB was switched to the femorofemoral extracorporeal membrane oxygenator (ECMO). Although he managed to recover from heart failure, his discharge was delayed due to the ischemic injury of the lower limb secondary to cannulation for ECMO. We reviewed the case and literature, placing emphasis on the predisposing factors and appropriate management.

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aorta. The stent was unable to be retrieved into the guide catheter, as it was distorted. A goose neck snare was used successfully to catch the stent in the ascending thoracic aorta and retrieved the stent externally via the arterial sheath.

PURPOSE: Natural orifice transluminal endoscopic surgery (NOTES) is a new operation technique that utilizes natural orifices of the patient's body with the intention to puncture hollow viscera in order to insert an endoscope into a peritoneal cavity for incisionless surgery. The aim of this study was to evaluate the safety and feasibility of endoscopic cecectomy through the rectum in one dog and the vagina in another dog. METHODS: This study was performed in two beagle dogs for rectal and vaginal approaches. A five-milimeter trocar was inserted into the abdominal cavity by the Hasson method and intra-abdominal pressure was maintained at 5 mmHg with CO2. After pneumoperitoneum was accomplished, the rectum or vagina was incised with a needle knife and a one-channel gastric endoscope was inserted into the abdominal cavity. Counter-traction was performed using a laparoscopic grasper introduced via the 5 mm trocar in the umbilicus. The cecum was dissected from the base by using a needle knife with the aid of laparoscopic counter-traction. The resected cecum was retrieved through the anus or vagina without pouch bag. The incised rectum was closed by using 90-degree endoclips whereas the incised vagina was not repaired. RESULTS: Cecectomies were successfully performed with both transrectal and transvaginal routes. Both cases had no complication and recovered from surgery uneventfully. CONCLUSION: Endoscopic cecectomy with hybrid NOTES are feasible and safe. With the improvement of surgical experiences and further instrumental development, NOTES can be one option for human intestinal surgery.

Endovascular aneurysm repair (EVAR) has been recommended as an alternative to open aneurysm repair. The risk of severe perioperative complications is lower than that in open surgical repair; however, late complications are more likely. After EVAR, regular yearly surveillance by duplex ultrasonography or computed tomography is recommended. We report the case of a 67-year-old man with a severely kinked left iliac branch of the stent graft 10 years after EVAR. He had not undergone regular follow-up during the last 4 years. We realigned the endograft kink by percutaneous transluminal angioplasty.

Familial benign hypocalciuric hypercalcemia (FBHH) is an autosomal dominant trait with high penetrance, clinically manifestating a relatively benign, lifelong, persistent hypercalcemia and hypocalciuria without hypercalcemic related complications. The calcium-sensing receptor (CaSR) plays an important role in the regulation of PTH secretion and calcium metabolism. Here we present a family with FBHH of an autosomal dominant inheritance. A heterozygous mutation of E297K (GAG -> AAG, exon 4) of CaSR gene was found in 3 family members. To our knowledge, it is the first confirmed case of FBHH with CaSR gene mutation in Korea.

Coronary artery aneurysms are detected rarely during coronary angiography, and are associated with injury to the mechanical vessel wall during percutaneous coronary intervention. Potential causes also include atherosclerosis, congenital defects, connective tissue disorders, vasculitis, infection, drug-related injury, and trauma; it can also be idiopathic. The complications of coronary artery aneurysms vary, but they rupture only rarely. However, there is no consensus treatment strategy for coronary artery aneurysm after coronary intervention. We report a case of a 55-year-old male who developed a coronary artery aneurysm and in-stent restenosis after percutaneous coronary intervention with a drug-eluting stent. The aneurysm was treated successfully with the implantation of a graft stent.

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a rare case of dislodgement of two intracoronary stents. On withdrawal of two balloon catheters, one with a guide wire was mechanically distorted from the left main (LM) to the proximal left anterior descending artery (LAD) while the other was dislodged from the LM to the ostial left circumflex artery. The stent in the LAD could not be retrieved into the guide catheter using a Goose neck snare, because it was caught on a previously deployed stent at the mid LAD. A new stent was quickly deployed from the LM to the proximal LAD, because the patient developed cardiogenic shock. Both stents, including a distorted and elongated stent, were crushed to the LM wall. Stent deployment and crushing may be a good alternative technique to retrieving a dislodged stent.
