The Q-switched lasers which was introduced under the concept of selective photothermolysis. Q-switched Nd:YAG laser, which targets dark pigments in a longer wave length (1064 nm) that has less absorption by melanin, can effectively treat deep tattoos with less pigmentary alterations. We report our experience over the past 3 years in treating 565 patients with tattoos and cutaneous pigmented lesions using the Q-switched Nd:YAG laser. Patients were exposed with a pulse duration of 10 ns and fluences of 6, 7 J/cm2(1064 nm) or 12, 14 J/cm2(532 nm), in exposure spots of 2 mm or 3 mm, at intervals of 4 weeks. Q-switched Nd:YAG laser was effective in removing deep pigmented lesion with 1064 nm, and colored inks with 532 nm. Seventy-three percent of amateur black pigmented lesion were > 75% clear after four to ten treatment. Ninty-eight percent of professional black pigmented lesion were > 75% clear after two on eyebrow, six to eight on extremity and trunk. No significant side effects, including pigmentary changes or scarring, were noted.

Bleeding frorn the duodenal varix is an unusual event. Upper gastrointestinal endoscopy is the diagnostic procedure of choice in diagnosing duodenal varices. If performed during active bleeding, it can differentiate between esophageal and duodenal varices as the source, which has important therapeutic implications. A thorough examination of the duodenum for varices is important in an upper gastrointestinal hemorrhage. Treatment modalites for bleeding duodenal varices are sclerotherapy, varix suture ligation, portocaval shunt, and duodenal resection. Although endoscopic sclerotherapy has lirnited success in controlling active duodenal varix as initial treatment, endoscopic injection sclerotherapy is a useful first-line therapeutic measure in the treatment of bleeding duodenal varices. In this study we present a case of a ruptured duodenal varix, which was defected by an endoscopy, in a 61-year-old male. An endoscopic examination showed small and nonbleeding esophageal varices and a prominant ulcerated varix was identified in the 2nd portion of the duodenum. Endoscopic sclerotherapy was performed by injecting ethanolamine oleate into the varix. Our report demonstrate that endoscopic sclerotherapy can be efficient even in the presence of acute bleeding and that it can provide a definitive method of curing of a bleeding duodenal varix.

Intramural duodenal hematoma is an uncommon condition, which usually develops after blunt abdominal trauma. It is also reported as a complication of anticoagulant therapy, blood dyscrasia, pancreatic disease, and diagnostic and therapeutic endoscopy. The typical clinical pictures of intramural duodenal hematoma consist of upper abdominal pain, vomiting, fever, and hematochezia, and it is rarely accompanied by intestinal obstruction, peritonitis, and pancreatitis as its complication. We report a case of intramural duodenal hematoma extended to peritoneal cavity, and accompanied by acute pancreatitis following therapeutic endoscopy for duodenal ulcer bleeding in a 32-year-old man who was on maintenance of anti-coagulation therapy after valvular heart surgery.

The radial artery as a graft for myocardial revascularization was introduced by Carpentier et al. in the early 1970s. Mid-term results were unfortunately discouraging, and the clinical experience with this graft was interrupted. At the end of the 1980s, these authors reproposed the same arterial conduit with more satisfying results, because of improved technique and pharmacological management of the graft. Between October 1994 and July 1995, 36 patients underwent myocardial revascularization with a radial artery graft in Sejong General Hospital. Left internal mammary artery was concomitantly used as a pedicled graft in 34 patients. Fifteen patients(42%) had a complete arterial graft revascularization. A total of 123 distal anastomoses were performed(average 3.4 per patient), including 36 left internal mammary artery grafts(two sequential in 2 patients), and 23 saphenous vein grafts. The remaining 64 distal anastomoses were performed with radial artery grafts (mean 1.8 per patient). The radial arteries were anastomosed to the circumflex(n=38), diagonal( n=18), right coronary(n=6), and left anterior descending coronary artery(n=2). The percentage of radial artery graft anastomoses(64) to the total anastomoses(123) was 52%. The radial artery was used as a single graft in 10 patients, as a sequential graft in 25 patients, and two grafts in 1 patient. Twenty patients underwent associated procedures : coronary endarterectomy(14), coronary artery patch angioplasty(4), mitral valve repair(1), and repair of ventricular septal rupture(1). One patient died of low cardiac output syndrome and the others had no perioperative myocardial infarction. There are no ischemic and functional complications in the arm or hand after removal of the radial artery. Only 1 patient required reexploration of the arm, for the hematoma evacuation, and 2 patients complained transient thumb dysesthesia of the side of the havested arm. This dysesthesia improved within one month. Postoperative angiographic controls were obtained in 11 patients(31%) postoperative 79 to 210 days(mean 126 days). The patency rate were as follows : left internal mammary artery(100%), saphenous vein(100%), and radial artery(95%). We concluded that the radial artery is useful alternative graft, but long term clinical and angiographic studies are required to dertermine whether wider application is warranted.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is the most common organism associated with nosocomial infections. MRSA infections are becoming increasing important because they have emerged no only as healthcare-associated (HA) infections but also as community-associated (CA) ones. This study examined the moleculo-epidemiology of MRSA, which was isolated from nasal swabs in the intensive care unit (ICU) at Konyang University Hospital. MRSA are classified into HA-MRSA and CA-MRSA. METHODS: From June to September 2006, 353 patients who were admitted to the ICU in Konyang University Hospital were enrolled in this study. Single nasal swabs were obtained for culture in the ICU on the 1st day. Pulsed-field gel electrophoresis and the antimicrobial resistant patterns were analyzed between HA- and CA-MRSA. An antimicrobial sensitivity test was also performed. RESULTS: Forty two strains of MRSA were isolated from 353 patients (11.9%). Among the 42 isolates, HA-MRSA and CA-MRSA were found in 33 (78.6%), and 9 (21.4%), respectively. Eleven different PFGE types (type A to K) were identified. Types A (n=9) and B (n=7) were the most common for HA-MRSA, and types A (n=2) and B (n=2) were identified in CA-MRSA. The proportion of types A and B in CA-MRSA (44.4%) was similar to that in HA-MRSA (48.5%). The rates of resistance rates to erythromycin and ciprofloxacin were higher in HA-MRSA than in CA-MRSA. CONCLUSION: The rate of isolation of MRSA in an ICU setting was 11.9%. HA-MRSA was isolated more frequently than CA-MRSA. The rate of resistance of HA-MRSA to erythromycin and ciprofloxacin was higher than that of CA-MRSA. Despite the small number of subjects, the main isolates (type A and B) of CA-MRSA were similar to those of HA-MRSA.
