During tumor progression, a subset of cells acquires metastatic properties, presumably through a series of genetic alterations. As the result, cells detach from the primary tumor, penetrate the basement membrane and invade the adjacent structures including lymph and blood vessels. Loss of adhesive functions and gain of new adhesive functions are thought to play a crucial role in this metastatic cascade. Since tumor metastasis is the principle cause of death for cancer patients including colon cancer, there is a consensus that a search for tools that allow effective assessment of the metastatic potential of tumors is a prime goal for cancer research. An immunohistochemical study of cell adhesion molecules, CD44H and its variant CD44v6, was done to evaluate their relationship with known prognostic factors related to the progression and metastasis of colorectal carcinoma in 94 cases of colorectal carcinoma tissues. The results were as follows. The CD44H expression was detected in 90 (95.7%) and CD44v6 in 53 (56.4%) out of 94 cases of colorectal carcinoma, and the CD44H was overexpressed in tumor tissue more than in normal mucosa in 62% of the cases. The expression rates of both protein were not significantly correlated with age and sex of the patients, invasion depth, lymph node metastasis, tumor differentiation, and tumor site. The coexpression of CD44H and CD44v6 in tumor was significant (p<0.05). The above results suggest that overexpression of CD44H and loss of function to control the alternative splicing of CD44 mRNA resulting in CD44v6 expression and alteration of adhesive function are closely associated with tumorigenesis of the colorectum.

Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

Objectives: Attention deficit/hyperactivity disorder (ADHD) is a condition characterized by inattention or hyperactivity and impulsivity that hinders function and development. The purpose of this study was twofold, that is, to check the diagnostic rate of ADHD, which is first diagnosed in adulthood as well as in childhood, and to compare drugs prescribed to children and adult patients. Methods: This study utilized Health Insurance Review & Assessment Service data from 1 January 2009 to 31 December 2018. Only first entered International Classification of Diseases diagnostic codes were collected. We set the first year as a clearance period, checked changes in drug prescriptions over the years, and investigated differences found between pediatric and adult patients. Results: The overall diagnostic rate of ADHD decreased from 71.9 to 69.7 per 100000 people between 2009 and 2012. This reducing trend was noticeable from 2012 and decreased to 43.7 by 2015, and then rose again to 65.4 in 2018. Extended-release formulation of the methylphenidate (ER-MPH) was found to be the most frequently used first drug. Conclusion Overall diagnostic rate decreased from 2009 to 2018, and the incidence of adult ADHD showed a steady increase. For children, ER-MPH was the most prescribed drug at all ages, while osmotic-release oral system formulation of the methylphenidate was most prescribed for adults.

BACKGROUND: Color Doppler echocardiography is sensitive in detecting mitral regurgitation and useful in quantitating its severity. The presence of an eccentric regurgitant jet suggests that regurgitation is caused by prolapsing or flail leaflet of mitral valve. Until recently the direction of regurgitant jet in mitral valve prolapse has been examined in a single(parasternal short axis view) or orthogonal plane using color Doppler echocardiography, and few in the apical rotation method of a transducer. The purpose of this study was to clarify the usefullness of the apical rotation method of a transducer in detection of the direction of mitral regurgitant jet and diagnosis of the sites of mitral valve prolapse. METHODS: Twenty four patients(8 men and 16 women, mean age:47.3+/-18.8 years) with mitral valve prolapse with eccentric regurgitant jet were examined by two-dimensional and color Doppler echocardiograply using conventional parasternal long and short axis views, and four apical longitudinal planes(four chamber, vertical, two chamber and transverse views) obtained by the apical retation method of a transducer. RESULTS: Thirty one regurgitant jets were detected in twenty four patients, eighteen patients had anterior, nine patints posterior, and three patients bi-leaflet(anterior and posterior) prolapse. In eighteen patients with anterior leaflet prolapse, ten had medial, eight had middle, three had lateral, and three had two portions(two, medial and middle; one, middle and lateral) prolapse. In nine patients with posterior leaflet prolapse, five had medial, three had middle, two had lateral, and one had two(medial and middle) scallop prolapse. CONCLUSION: Color Doppler echocardiography by the apical rotation method of transducer is useful in assessment of the site of prolapse in patients with mitral valve prolapse with eccentric regurgitation.

Both death certificates and postmortem examination certificates are used as proof of death. These certificates sometimes contain erroneous information but how frequently they do so is unknown. In particular, only a few studies have measured the accuracy of the cause and manner of death on Korea death documents. In this study, we compared the cause and manner of death on both kinds of certificates with those on autopsy reports to determine the frequency of errors, and to identify way to improve the accuracy of these certificates. In 2012, 528 autopsies were requested of out institute, and certificates were submitted in 241 of the cases. The manner of death was classified as natural, unnatural, or unknown. The cause of death in the autopsy report matched that on the death certificate in 37 of 63 cases (58.7%), and the manner of death matched in 40 of 63 cases (63.5%). The cause of death in the autopsy report matched that on the postmortem examination certificate in 62 of 178 cases (34.8%), and the manner of death matched in 74 of 178 cases (41.6%). Death certificates and postmortem examination certificates are important documents. We identified many incorrect reports of causes and manners of death on both kinds of documents, especially the postmortem death certificates. These inaccuracies are presumably due to a lack of forensic information and education, as well as lack of interest on the part of medical doctors.

BACKGROUND AND OBJECTIVES: Voice therapy is proven to be effective, but patients are reluctant to receive the therapy when physicians recommend it. This phenomenon may due to patients'lack of trust in or low satisfaction level of the therapy. This study aimed to evaluate patients'satisfaction level after voice therapy and identify factors that could increase the satisfaction. MATERIALS AND METHODS: First, the fraction of patients who were recommended voice therapy ahead and completed it was studied, and survey was conducted on those who finished ten voice therapy sessions. The patients'1) satisfaction level during the therapy, 2) satisfaction level about physician's explanation about the therapy, 3) willingness to recommend, 4) satisfaction level about the results were assessed, and was correlated with overall satisfaction level. In each category, patients' gender-, age-, and disease type-related differences were analyzed. RESULTS: Patients under 19 years old were most satisfied during the voice therapy; patients above 40 years old showed statistically significantly higher satisfaction level regarding satisfaction with physician explanation about treatments and with treatment results compared to other ages groups. Patients above 40 also showed the highest willingness to recommend. 26.5% of patients either refused to or discontinued voice therapy. 84.3% were satisfied with treatment results. Considering variabilities among factors, patients'satisfaction with physician explanation about treatment and willingness to recommend had positive correlation. CONCLUSION: Though 26.3% of patients received voice therapy when physicians recommended, patients who completed the therapy were overall satisfied.

Isolated ACTH deficiency is a uncommon disorder causing secondary adrenocortical insufficiency. Less than 200 cases have been reported in the world. The major clinical manifestations are hypoglycemia, weight loss, hypotension, anemia, weakness, nausea, inability to excrete water load, and hyponatremia. A 56-year-old male was admitted because of weakness, fatigue, nausea and vomiting. He was pallor and not associated with hyperpigmentation. The basal plasma ACTH and cortisol levels were 8.30 pg/ml and 0.6 ug/dl. The serum cortisol did not response to rapid ACTH stimulation test. On combined pituitary stimulation test, the cortisol did not response to insulin-induced hypoglycemia. Other anterior pituitary hormones showed normal responses except elevated prolactin level. Six months after glucocorticoid replacement therapy, the elevated basal prolactin level returned to normal. Brain MRI did not show any anatomic abnormalities of the sellar and suprasella area. We report a case of isolated ACTH deficiency accompanied by hyperprolactineia, which respond to glucocorticoid replacement therapy.
