3.A Case of Optic Nerve Atrophy with Severe Disc Cupping after Methanol Poisoning.
Korean Journal of Ophthalmology 2011;25(2):146-150
We report a rare case of optic nerve atrophy with severe disc cupping resulting from methanol poisoning. A 30-year-old man presented to the hospital complaining of decreased visual acuity in both eyes a day after drinking alcohol containing methanol. His initial visual acuity allowed for only visualizing hand motion and not corrected in either eye. Initial intraocular pressure was within normal limits in both eyes. Initial fundus examination showed optic disc swelling in both eyes. Four years later, he visited our hospital for an eye evaluation. Visual acuity in both eyes still only allowed for visualizing hand motion. No nystagmus was observed in either eye during the optokinetic nystagmus test, and no waves were found in a visual evoked potential test. No specific change was noted on brain magnetic resonance imaging. On fundus examination, there was disc pallor in both eyes and disc cupping with a high cup/disc (C/D) ratio above 0.9 in the left eye. C/D ratio of the right eye was 0.5. Methanol poisoning may induce glaucomatous disc cupping in the late stage as well as optic atrophy. One possible mechanism of disc cupping is ganglion cell loss due to acute demyelination of the retrobulbar optic nerve. This report is the first photographic evidence of methanol induced optic disc cupping in Korea.

The incidence of gastric cancer is high in old age group and low in young age group, extremely rare in child age. So the diagnosis of gastric cancer in young age is often delayed, and this, with other factors such as poorly differentiated histopathologic tendency and rapid growing nature, makes the prognosis poorer than in other age guoup. Therefore it should always be remembered that the young who has gastric symptom may have malignancy in his stomach in spite of the age. We report a case of early gastric cancer in a 16-years old male with the review of the literature.

As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

7.Trampoline-related injuries in Korea

Journal of the Korean Medical Association 2018;61(2):111-115
The growing popularity of trampolines in Korea has resulted in a significant increase in the number of injuries associated with their use. However, little research has been conducted into trampoline-related injuries in Asian countries, including Korea and the incidence and characteristics of trampoline-related injuries have rarely been reported. In a review of the very few studies on these injuries in Korea, the mean age at injury was younger than has been reported in previous studies from other countries, and 46% of patients experienced fracture. Most injuries (82%) occurred in commercial facilities. In Korea, the safety management of trampolines is insufficient. Hence, safety guidelines for the use of trampolines should be recommended by relevant medical professionals.

This study observed the changes of the glycogen content in extensor digitorum and soleus by electrical stimulation on the sciatic nerve with various frequencies, and the result were compared with those of treadmill running exercise. The results are summarized as follows ; The glycogen content of extensor digitorum longus was greater than that of the soleus in the normal group, and the reducing amount of glycogen content of extensor digitorum longus was greater than that of the soleus by overnight fasting. As the frepuency of electrical stimulation was increased by 2, 5 and 10Hz., the glycogen content of the extensor digitorum longus was slightly reduced or changed minimally. As the loading period of clectrical stimulation was increased to 30 and 90minutes, the glycogen content of extensor digitorum longus was much reduced from early stage, and that of the soleus was the same tendency as the frepuency increased. The glycogen content of the extensor digitorum longus was proportionally reduced by treadmill running excercise, and that of the soleus was much reduced from the early stage. In summary, based on the experimental evidence of this investigation, it showed the different physio-chemical responses of th fast and slow twitch muscle fibers by electrical stimulation, and also not the equal responses of muscle fibers by electrical stimulation and treadmill running exercise.

PURPOSE: Recently, there has been increasing number of trampoline injuries at our pediatric orthopedic clinic and emergency room. Therefore, this study is to analyze the prevalence of the trampoline injuries with emergency room surveillance. MATERIALS AND METHODS: Between September 2015 and February 2017, all patients under the age of 15 years, who visited emergency room of a teaching hospital with trauma and referred to the department of orthopedic surgery, was included; the cause of trauma was analyzed. The severity of injury was also evaluated and compared according to the cause of injury. RESULTS: There were a total of 1,807 patients under the age of 15 years who visited our emergency room during the study period. There were a total of 71 trampoline injuries (3.9%). There were 28 patients below the age of 5 years, and among them, 14 minor injury were recorded; 43 patients were over the age of 5 years and with 4 minor, 20 moderate, and 19 severe injuries. In the age between 5 and 15 years, the prevalence of mild injury was lower in trampoline injury compared with those of other sports injuries (9.3% vs. 34.0%) and the prevalence of severe injury was higher in trampoline injury (44.2% vs. 26.3%) (p=0.002). CONCLUSION: Our findings indicate that the incidence of trampoline injury was lower than other country, but it was more severe than injuries from other sports. With increasing incidence of trampoline injuries, parents should be more mindful that trampolines are not safe and stricter supervision may be necessary.
