An unusual case of homicide of a 21-year-old man who was smothered with a hot steam towel by his mother and a pastoress in the name of exorcism. Homicidal smothering in adults is rare, but does occur when the victims are not capable of defending themselves in situations such as chronic illness, old age, drug intoxication or when restrained by other people. In this case, distinct facial scalding was a clue to smothering with a hot steam towel.

Here we report an autopsy case of diabetic ketoacidosis (DKA) with severe hypertriglyceridemia (12,900 mg/dl). A 29-year-old woman with a history of type 1 diabetes was found dead at a motel. There was no injury on external inspection, but a lump of cheese-like material was noted in the heart at autopsy and peripheral blood plasma had a creamy appearance. After postmortem biochemical analysis, we made a diagnosis of DKA with severe hypertriglyceridemia and concluded that these unusual autopsy findings were caused by DKA and postmortem change. Uncontrolled diabetes often causes DKA and hypertriglyceridemia. To the best of our knowledge, this is the first report in Korea of DKA with severe hypertriglyceridemia diagnosed by autopsy.

4.Calcium, Vitamin D, and Colorectal Cancer
The Korean Journal of Gastroenterology 2023;82(2):47-55
Colorectal cancer has a high incidence and mortality worldwide, with Westernized lifestyles and diet being significant contributing factors. Vitamin D and calcium have been known to reduce the incidence of colorectal cancer by affecting cell differentiation, proliferation, and apoptosis. Despite observational studies which have suggested that a higher serum vitamin D level can lower the risk of colorectal cancer and improve survival rates, no large-scale randomized controlled trials to establish these benefits have been conducted to date. Calcium intake has also been found to have a beneficial role in reducing the incidence and improving survival rates of colorectal cancer in several observational studies. Moreover, intervention studies have proved its effect in preventing colorectal adenomas. However, there are few intervention studies that have identified the relationship of vitamin D and calcium with colon cancer. To elucidate the impact of vitamin D and calcium supplementation on colorectal cancer, well-designed and large-scale randomized controlled trials are necessary in the future.

The benign mesenchymoma, in which fibrous tissue is accompanied by two or more mesencymal components, occurs very rarely in the head and neck area. The majority appear in patients under 25 years of age, most commonly in the subcutaneous scalp, cheek, or tongue. There is a 20% recurrence rate. Wide surgical excision is the treatment of choice. We report a case of mesenchymoma in the nasopharynx which was removed by transpalatine approach with a brief review of literature.

BACKGROUND: DNA methylation and histone modification are dynamically linked in the epigenetic control of gene silencing and they play an important role in tumorigenesis. METHODS: To evaluate the role of histone deacetylase 1 (HDAC1) in the development of lung cancer and the relationship between a HDAC1 overexpression and p16INK4a hypermethylation, we performed immunohistochemical staining for HDAC1 in 76 lung cancer specimens (39 squamous cell carcinomas and 37 adenocarcinomas) that had been previously evaluated for their p16INK4a methylation status by real-time quantitative polymerase chain reaction. RESULTS: A HDAC1 overexpression (>50% of HDAC1 immunoreactive cells) was detected in 65 (85.5%) out of the 76 cases and it was more frequently seen in the squamous cell carcinomas (97.4%) than in the adenocarcinomas (73.0%) (p=0.002). The incidence of HDAC1 overexpression tended to be higher in the heavy smokers with more than 20 pack-years (p=0.067). Although there was no statistical significance, the frequency of p16INK4a hypermethylation in the cases with a HDAC1 overexpression (27.7%) tended to be higher than that in the cases without a HDAC1 overexpression (9.0%) (p=0.175). CONCLUSIONS: A HDAC1 overexpression might be involved in lung carcinogenesis, and especially in a subgroup of smoking and squamous cell carcinoma patients, and a HDAC1 overexpression may be associated with p16INK4a hypermethylation.

Although bladder cancers are very common, little is known about their molecular pathogenesis. It is known, that p53 alteration is found in about 60%p of muscleinvasive bladder cancer, necessiating aggressive therapy and poor outcome. We examined the nuclear expression of p53 protein, using D07 monoclonal antibody in the urine samples, from 31 patients with transitional cell carcinoma of the bladder to investigate the correlation of p53 overexpression with histologic grades and depth of invasion. The positive rate of p53 protein was 27%o in superficial bladder tumor, but increased up to 71% in the invasive bladder carcinomas. The overexpression of p53 protein increased according to Mostofi grading system from 18% in grade I, 45% in grade Il, and up to 100% in grade ill. The p53 expression tended to be higher in the invasive and high grade bladder cancers than in the superficial and low grade ones(p<0.05). These results suggest that immunohistochemical analysis of the urine specimen in the bladder cancer patients could be a useful method of screening for the presence of p53 mutant protein. The mutant p53 protein expression may be an indicator of bladder cancer with more proliferative potential and/or aggressive biologic behavior.

OBJECTIVE: We investigated the expression of chemokine receptors in human ovarian cancer to understand the role of chemokines in ovarian cancer development and metastasis. METHODS: Twenty-two cases of epithelial ovarian cancer were studied for expression of 13 chemokine receptors such as CXCR1-CXCR5 and CCR1-CCR8 by using semi- quantitative RT-PCR and immunohistochemistry. Moreover, we studied the relationship between the chemokine receptors expression and lymph nodes metastasis of ovarian cancers. RESULTS: As compared with normal ovarian tissues, ovarian cancer tissues showed higher mean expression levels of CCR1,3,4,5,7,8 and CXCR1,3,4. Of chemokine receptors, CCR7 revealed the significantly higher levels of expression in ovarian cancer tissues relative to normal tissues. In the cases of retroperitoneal lymph nodes metastasis, increased expression of CCR2,4 and CXCR 1,3,4 was observed although there was no statistical significance. CONCLUSION: These results suggest that there is a complex chemokine/chemokine receptor network in pathogenesis and the way of lymph node metastasis of ovarian cancer rather than a specific chemokine or chemokine receptor.
