PURPOSE: Lawn trimmers are widely used to cut the weeds around graves in South Korea, but they can cause ocular injury. We investigate at the emergency room the incidence and the clinical features of ocular trauma induced by lawn trimmers. METHODS: The authors analyzed 106 patients who visited Konyang University Hospital's emergency room from March 1, 2007, to October 31, 2011, because of ocular trauma caused by a lawn trimmer. Patients were sorted into two groups, severe ocular injury and mild ocular injury. RESULTS: Over a 5-year period, 106 patients with ocular trauma caused by a lawn trimmer underwent clinical study. Most of the patient (103 patients) were males, and the average age of the patients was 51.75+/-11.66 years. The incidence of ocular trauma peaked in the sixth decade of life. Most injuries occurred between July and September. Severe ocular injury developed in 46.2% of all patients. As age increased, so did the severity of the ocular injury. The impacting object was a small stone in 43.4% of all patients. Nobody wore protective gear. The most common diagnosis were corneal abrasion, followed by intraocular foreign body, corneal laceration, and sclera laceration. Fifty-four patients were followed up, and thirty-six patients of them had severe injury. The most common complication was a traumatic cataract. CONCLUSION: Ocular trauma induced by a lawn trimmer is more severe than general ocular trauma. We suggest that everyone using a lawn trimmer should wear protective gear and follow safety guidelines.

In vitro subcultures of bacteria can lead to genetic and phenotypic changes. This study aimed at investigating the effect of repeated subcultures on the adhesion, motility, cytotoxicity, and gastric inflammation caused by Helicobacter pylori. H.pylori SS1 strain was subcultured 64 times on agar plates containing Brucella broth and 5% bovine calf serum. The adhesion, motility, cytotoxicity, and gastric inflammation produced in Mongolian gerbils were compared between the first and 64th subcultured strain. The adhesion rates, following 3 hr exposure of AGS cells to either the first strain or the 64th-transferred strain, were 21% and 12%, respectively. The motility of the 64th-transferred strain decreased significantly when compared to the 1st strain (9.1 mm vs. 15.1 mm). The cytotoxicity index tended to be higher in the first strain than in the 64th-transferred strain (73.7% vs. 69.2%). The initial infection rate on the gerbils showed no difference between the two strains. However, chronic gastric inflammation of the first strain-infected gerbils was somewhat more severe than that of the 64th-transferred strain-infected gerbils. Therefore, the use of repeatedly subcultured strains of H. pylori in virulence experiments can lead to different results from thoses of the original strain.

PURPOSE: Defecography is a dynamic investigation which can influence clinical decision making in patients with pelvic outlet obstructive disease (POOD). The current study was designed to establish defecographic findings in patients with POOD. Specifically, we sought to assess the physiologic characteristics of categorized types by using anorectal physiologic tests. METHODS: One hundred seven patients (disease group; 45 men, 62 women) with POOD were retrospectively categorized as type I [non-relaxation of puborectalis (NRPR) only, n=19], type II [NRPR and rectocele, n=20], type III [NRPR, rectocele, and dynamic perineal descent (PD), n=17], type IV [deformed rectocele, mild-to-moderate fixed PD, and absence of NRPR, n=29], and type V [rectocele, severe fixed PD, and absence of NRPR, n=20] on the bases of defecographic findings. The ability to evacuate, the frequency/degree of intarectal intussusception (IRI), and the size of the rectocele were evaulated in these defecographic types of POOD. Age, duration of symptoms, and the physiologic findings of anal manometry and EMG/PNTML were compared for the five types. Eighteen healthy volunteers who had no defecation difficulty were used to estimate the normal findings of defecography. RESULTS: The age and the sex showed no significant differences among the types. The duration of symptoms was gradually lengthened from type I to V (P<0.01). The ability to evacuate in patients with POOD was significantly worse (failed to effectively evacuate) compared to that in the healthy volunteers (P<0.01). The frequency of IRI was increased more and more from type I to V (P<0.01). The size of the rectocele was significantly increased in types V compared to the other types (P<0.01). Manometric and neurologic findings, including EMG/PNTML, revealed no significant differences among the types. CONCLUSIONS: Even though there were no specific differences in the findings of the anal manometric and neurologic tests, the evacuation dynamics; were different in the five defecographic categories of patients with POOD. Specifically, these differences were relevants to the presence of NRPR, rectoceles, IRI, and perineal descent.

Diverticular bleeding is a common cause of lower gastrointestinal bleeding in adults. Most of colonic diverticular bleeding stop spontaneously without any treatment. But diverticular bleeding develops at arterial vessel, which results in massive bleeding in a short period of time and may shows recurrence. Acute lower intestinal bleeding has been treated with heater probe coagulation, injection therapy, bipolar coagulation and endoscopic hemoclips. We experienced a 67-year-old woman presented hematochezia. Emergency colonoscopy was performed and showed a diverticulum with a visible vessel at the cecum. Hemostasis with hemoclip was successfully done. We herein report a case of hemostasis by capping a diverticulum of the colon with hemoclips.

Duodenal varices are a rare site of hemorrhage in patients with intrahepatic and extrahepatic portal hypertension, but their bleeding is life-threatening complication. Diagnosis of duodenal varices may be difficult, requiring careful inspection of the duodenal bulb during endoscopy. Diagnosis of duodenal varices may also be revealed using angiography and transhepatic portography. Treatment of duodenal varices include endoscopic injection sclerotherapy (EIS), endoscopic variceal ligation (EVL), surgical procedures, and interventional radiology. A 50-year-old woman with liver cirrhosis was admitted with melena and hematochezia. An endoscopy on admission showed esophageal and fundal varices without any bleeding stigma. Colonoscopy showed moderate amount of fresh blood in the terminal ileum. 99mTc-labelled RBC scan showed a suspicion of a distal jejunal bleeding. She had explo-laparotomy of small bowel segmental resection based on 99mTc-labelled RBC but rebleeding occured. Selective mesenteric angiography failed to reveal the source of bleeding. Repeat endoscopy revealed undetected duodenal varix which was covered with fresh blood clots. Endoscopic injection sclerotherapy with n-butyl-2-cyano acrylate (Histoacryl) was performed and achieved succesful hemostasis.
