A death due to angle grinder injuries is reported. An angle grinder is a widely used electronic device at a working place or at home. A deceased old man and an angle grinder without a protective guard were found at the living room in his house where he had been renovating. The wound of the victim's head showed an oblique laceration, skull fractures and tearing on the brain, embedded with grinder disk fragments. A small intraparenchymal hematoma was in the midbrain, which could be the cause of the fall leading to the accident. Disreard of the cause of the accident, the absence of a protective guard and removal of one hilt might have contribute to the death of the victim.

BACKGROUND: The purpose of this study is to obtain the accurate information on the obesity indices, such as body mass index(BMI), relative weight and waist-hip ratio(WHR) and to investigate their relationship in order to assess the childhood and adolescent obesity more appropriately. METHODS: In May, 1995, a total of 6943(male; 3469, female; 3474) students from primary, middle and high schools in Seoul were selected and each students height, weight, waist and hip circumference data were collected. RESULTS: The BMI increased with age in both sexes. From age 12 to 16, values of BMI 50th percentiles for females exceeded those for males. And the BMI 95th percentiles at the age of 13 to 14 years were higher for females than for males. The prevalence of obesity by relative weight was higher in males than in females(male ; 17.9%, female ; 13.1%). The WHR was higher in males than females in all age group and decreased with age in both sexes, showing more sharp reduction in females. Strong correlations were observed between the BMI and the relative weight, and the BMI and the relative weight correlated closely with WHR. The WHR was significanly higher in obese group' than in non-obese group. In the female obese group aged 6 to 11 years, no significant correlation was found between the relative weight and the WHR. CONCLUSIONS: There were significant relationships between the indices of obesity and body fat distribution. This study suggests that WHR as well as BMI and relative weight might be useful in assessing the childhood and adolescent obesity.

BACKGROUND: The prevalence of dementia is estimated to be as high as 11.3% among coummunity-dwelling persons over 65 years of age in Korea. The fear of dementia for both patients and families is growing because of the chronicity and progressiveness of the disease. Though the recognition, evaluation, and management of patients with dementia are important for the care of older pateint, unfortunately, MMSE takes 5 to 10 minutes to administer and is cumbersome to carry for all elderly patients in busy office. The Clock Drawing Test has been known as valid, easily administered and low cost screening procedure for the congnitive impaiment associated with dementia in general geriatric clinic population. In this study, we assessed the usefulness of this measure as a screening test for dementia, on the basis of the correlation between clock drawing and MMSE-K. METHODS: The subjects for this study consisted of 47 elderly who visited to two elderly clubs in Seoul from April 1996 through June 1996 or the outpatient department of Family medicine of the Ehwa Mok-dong hospital. They received the Mini-Mental Status Exam and the Clock Drawing test. Three observers evaluated them by ratings from 10(best) to 1(worst). Inter-rater reliability of scores from the Clock Drawing Test was assessed and Pearson correlation coefficients were used to examine the relationships between scores from the Clock Drawing Test and MMSE-K. RESULTS: Their mean age was 75.4 years with range of 65 to 91 years. There were 34 women and 13 men. Correlations between individual raters was highly significant(y=0.8939, 0.8552, and 0.8698, respectively ; P<0.01). Compared to scores on MMSE-K, rating from clock drawings by each of 3 raters revealed statistically significant correlations(y=0.7164, 0.7398, and 0.6884, respectively ; P<0.01). CONCLUSIONS: The clock drawings can be rated reliably by even untrained observers and performance on this task relates significantly to performance on MMSE-K of severity. We confirmed the usefulness of clock drawings as a simple, easily administered, low cost, and reliable general screening tool for dementia in a general geriatric clinic population.

Journal of Gastric Cancer 2010;10(2):55-62
PURPOSE: We evaluated the clinicopathological charicterics and prognostic impacts of lymphatic vessel invasion in gastric cancer without lymph node involvement. MATERIALS AND METHODS: Among 1,795 patients who underwent gastric surgery with gastric cancer at the department of surgery, Hanyang university college of medicine from June 1992 to March 2009, we retrospectively evaluated 890 patients with lymph node negative gastric cancer. RESULTS: The lymphatic vessel invasion correlated significantly with tumor stage, age, tumor size, perineural invasion and operation method. The survival rates were only significantly different between the patients with and without lymphatic vessel invasion in patients with stage Ia (P=0.036). Univariate and multivariate analysis demonstrated that blood vessel invasion and preoperative serum CEA level were significant factor influencing the survival rate in lymph node negative gastric cancer patients with lymphatic invasion. CONCLUSIONS: In patients with lymph node negative gastric cancer, the survival rate is significantly lower in those with lymphatic vessel invasion than in those without. Especially, in patients with stage Ia gastric cancer, the survival rates is significantly different between those with and those without lymphatic vessel invasion. Blood vessel invasion and preoperative serum CEA level is an adverse prognostic indicator in patients with stage Ia gastric cancer with lymphatic invasion. Thus we should consider further adjuvant therapies in case of need and need to show more concern to identify gastric cancer patients early at risk for recurrence.

PURPOSE: There are few studies that have focused on the predictors of recurrence after gastrectomy for gastric carcinoma. This study analyzed the patients who died of recurrent gastric carcinoma and we attempted to clarify the clinicopathologic factors that are associated with the timing of recurrence. MATERIALS AND METHODS: From June 1992 to March 2009, 1,795 patients underwent curative gastric resection at the Department of Surgery, Hanyang University College of Medicine. Among them, 428 patients died and 311 of these patients who died of recurrent gastric carcinoma were enrolled in this study. The clinicopathologic findings were compared between the 72 patients who died within one year after curative gastrectomy (the early recurrence group) and the 92 patients who died 3 years after curative gastrectomy (the late recurrence group). RESULTS: Compared with the late recurrence group, the early recurrence group showed an older age, a more advanced stage, a poorly differentiated type of cancer and a significantly higher tendency to have lymphatic invasion, vascular invasion and perineural invasion.Especially in the gastric cancer patients with a more advanced stage (stage III and IV), the early recurrence group was characterized by a significantly higher preoperative serum carcino embryonic antigen level, perineural invasion and a relatively small number of dissected lymph nodes. CONCLUSIONS: The clinicopathologic characteristics of recurrent gastric cancer are significantly different according to the stage of disease, and even in the same stage. For the early detection of recurrence after curative surgery, it is important to recognize the clinicopathological factors that foretell a high risk of recurrence. It is mandatory to make an individualized surveillance schedule according to the clinicopathologic factors.

Mandible fractures have recently been managed by rigid internal fixation with miniplate and screws more often than by traditional interosseous wiring methods. The purpose of this paper was to compare traditional interosseous wiring with miniplate fixation in open reduction of mandible fracture, especKweonially in operative results and costs. From June of 1989 to June of 1998, there were 142 patients, admitted to the department of Plastic and Reconstructive Surgery, Chun-Cheon Sacred Heart Hospital, Hallym University. Of those, 101 patients were managed by open reduction, and among them, 83 patients were treated with miniplate fixation, but 18 patients had recently been treated with interosseous wiring methods. No significant difference was noted between the two groups in terms of complications, but the overall cost of miniplate and screws was higher than interosseous wiring, while the mean operative time was longer in the group treated with miniplate fiation. The authors recommend interosseous wiring technique for patients with mandible fractures requiring open reduction and fixation, except for absolute indications of rigid internal fixation.

9.Anterior Cervical Microforaminotomy.

Anterior cervical microforaminotomy is the one of surgical options for treating cervical spondylotic lesions manifested by radiculopathy or myelopathy. This minimally invasive surgical procedure is gaining popularity due to the recent trends of avoidance of spinal fusion resulting in loss of the physiologic spinal motion and developing a future adjacent segment syndrome. Although the spinal fusion still remains a gold standard procedure for degenerative cervical spinal diseases, the eager for maintaining the function of the motion segment is another issue for contemporary spinal surgeons. Anterior cervical microforaminotomy is a target-oriented operation that decompresses the nerve root or spinal cord without destruction of the spinal anatomical functional unit. Unlike to other procedures including total or partial resection of the intervertebral disc, this surgical procedure removes only a small part of the uncovertebral joint or vertebral body. Through this narrow corridor, adequate decompression of the nerve root or spinal cord can be achieved while preserving functional motion. Technical variations of the original anterior cervical microforaminotomy have been continuously developed to minimize the concerns for the postoperative disc height loss and instability. As of now, the anterior cervical microforaminotomy and its technical variations have been proved to be an excellent procedure for treating the cervical spondylotic radiculopathy from literatures review. But the long-term clinical results and the efficacy of the procedure for cervical myelopathy still remain to be seen.

PURPOSE: The lateralization of cognitive functions in crossed aphasia in dextrals (CAD) has been explored and compared mainly with cases of aphasia with left hemisphere damage. However, comparing the neuropsychological aspects of CAD and aphasia after right brain damage in left-handers (ARL) could potentially provide more insights into the effect of a shift in the laterality of handedness or language on other cognitive organization. Thus, this case study compared two cases of CAD and one case of ARL. MATERIALS AND METHODS: The following neuropsychological measures were obtained from three aphasic patients with right brain damage (two cases of CAD and one case of ARL); language, oral and limb praxis, and nonverbal cognitive functions (visuospatial neglect and visuospatial construction). RESULTS: All three patients showed impaired visuoconstructional abilities, whereas each patient showed a different level of performances for oral and limb praxis, and visuospatial neglect. CONCLUSION: Based on the analysis of these three aphasic patients' performances, we highlighted the lateralization of language, handedness, oral and limb praxis, visuospatial neglect and visuospatial constructive ability in aphasic patients with right brain damage.
