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.

PURPOSE: The purpose of this study was to investigate the relationships among variables of somatic attribution, chronic pain, depression and chronic fatigue in the elderly. METHODS: Empirical data for testing hypothetical models was collected from 311 people over 65 years old in a community settings in Seoul, Korea in June and July, 2000. Data were analyzed by descriptive statistics and correlational analysis using pc-SAS program. The Linear Structural Modeling(LISREL) 8.0 program was used to find the best fit model which explained causal relationship of variables. RESULT: According to Accepted model, the relation of variables is that the somatic attribution is the influencing variable to chronic pain and depression and chronic pain and depression is the influencing variable to chronic fatigue. CONCLUSION: The findings of this study give useful information to construct intervention program relating chronic pain, depression and chronic fatigue for the elderly.

BACKGROUND: Epithelial tumor cells with a CD44(+)/CD24(-/low) immunoprofile may have the ability to cause breast cancer. We studied these cells and their clinicopathological significance. METHODS: The clinicopathologic findings of 100 invasive ductal carcinoma (IDC) cases and 45 ductal carcinoma in situ (DCIS) cases were reviewed. CD44(+)/CD24(-/low) tumor cells were identified by immunohistochemistry, and their clinicopathological implications in IDC and DCIS were analyzed. RESULTS: IDC with a high prevalence of CD44(+)/CD24(-/low) tumor cells was significantly associated with larger mass, higher grade, estrogen receptor (ER) negativity, and tumor cells with a higher frequency of metastasis. The proportion of CD44(+)/CD24(-/low) tumor cells in IDC, and its DCIS components was not significantly different, whereas the proportion of CD44(+)/CD24(-/low) tumor cells was higher in DCIS than in the DCIS component of IDC (p < 0.001). CONCLUSIONS: IDC with a high prevalence of CD44(+)/CD24(-/low) tumor cells might correlate with aggressive features, such as ER and higher grades. Moreover, the proportion of CD44(+)/CD24(-/low) tumor cells in the DCIS components of IDC and DCIS might harbor different biology, which may lead to differences in cancer progression and early carcinogenesis.

Papillary thyroid carcinoma with nodular fasciitis-like stroma (PTC-NFS) is a rare variant of PTC. The term 'PTC with fibromatosis-like stroma' has been used as a synonym to describe this variant. It is characterized by extensive proliferation of fibroblasts and myofibroblasts in the tumor stroma, which occurs in up to 80% of the tumors. We herein describe a case of PTC-NFS which developed in a 49-year-old woman with the demonstration of findings of ultrasonography, fine needle aspiration cytology and histological examination of the lesion. To characterize the stromal components, we investigated the expression of several immunohistochemical markers which have been shown to be expressed differently in nodular fasciitis (NF) and fibromatosis (FM). The immunostaining results demonstrated nuclear and cytoplasmic accumulation of beta-catenin, cytoplasmic transforming growth factor-beta expression and nuclear Smad expression in the stromal cells, suggesting that the stromal cells in this case have similar molecular profiles to those of FM rather than NF.

An epidermoid cyst of the cecum is extremely rare; only eight cases have been reported in the literature. A 63-year-old woman was admitted to Kyung Hee University Medical Center with a colonic mass that had been discovered incidentally during a regular health check-up. The radiographic impression was that this mass was a gastrointestinal stromal tumor. During surgery, an exophytic mass in the cecal wall was resected by using an ileocecectomy. Based on the macroscopic and the microscopic findings, this case was identified as an epidermoid cyst of the cecal wall. We report this case to discuss the origin of this entity and the unusual nature of our case.

BACKGROUND: Isocitrate dehydrogenase (IDH) catalyzes the oxidative decarboxylation of isocitrate to yield alpha-ketoglutarate (alpha-KG) with production of reduced nicotinamide adenine dinucleotide (NADH). Dysfunctional IDH leads to reduced production of alpha-KG and NADH and increased production of 2-hydroxyglutarate, an oncometabolite. This results in increased oxidative damage and stabilization of hypoxia-inducible factor alpha, causing cells to be prone to tumorigenesis. METHODS: This study investigated IDH mutations in 61 Ewing sarcoma family tumors (ESFTs), using a pentose nucleic acid clamping method and direct sequencing. RESULTS: We identified four cases of ESFTs harboring IDH mutations. The number of IDH1 and IDH2 mutations was equal and the subtype of IDH mutations was variable. Clinicopathologic analysis according to IDH mutation status did not reveal significant results. CONCLUSIONS: This study is the first to report IDH mutations in ESFTs. The results indicate that ESFTs can harbor IDH mutations in previously known hot-spot regions, although their incidence is rare. Further validation with a larger case-based study would establish more reliable and significant data on prevalence rate and the biological significance of IDH mutations in ESFTs.

Papillary thyroid carcinoma (PTC) in children under ten years old is very rare. To date, 18 cases of PTC in children under ten years old (including our two cases) have been reported in Korea. Here, we describe two cases of recurrent PTC with follicular variant and conventional type in an 8-year-old boy and a 7-year-old boy, respectively, and discuss clinicopathologic and molecular characteristics that differ in pediatric patients from adults.
