Apocrine sweat gland carcinoma is a very unusual malignant skin adnexal tumor and mostly occurs in areas where apocrine elands are abundant namely. axilla. upper arm. scalp. eyelid. vulva and external auditory meatus. The scrotal location is not yet reported. We report a case of apocrine sweat gland carcinoma of scrotum in a man aged 85, which was managed by local excision. The histologic finding is that of poorly differentiated adenocarcinoma. Evidence of decapitation secretion typical or apocrine glands. is present in some areas.

Fibrous dysplasia is a common benign disorder of bone in which normal bone marrow is replaced with fibro-osseous tissue. As PET/CT is increasingly used for the staging of different malignant disease, incidentally found fibrous dysplasia with increased FDG uptake may mimic metastasis. We report on a 46-year-old woman with fibrous dysplasia who underwent PET/CT because of suspected recurrence of breast cancer and was misdiagnosed as a bony metastasis with a focal FDG uptake on left proximal femur. This lesion was interpreted as fibrous dysplasia based on MRI in addition to the plain radiographs. We conclude that MRI in addition to radiography may help to differentiate fibrous dysplasia mimicking metastasis on PET/CT in the patients with malignancy.

It is essential to estimate the liver size in the diagnosis of liver disease. Many approaches have beenattempted in the evaluation of liver size such as measurement of length, area and volume. Among these, area andvolume measurements are accurate but complicated. So various linear measurements including Pfahler's method havebeen commonly used. But to our knowledge, there was no report about linear diameter of liver in Korean adualts. Asingeneral, larger patients are likely to have larger liver than smaller ones, it seems to be more ideal toevaluate the liver size using relative ratio rather than absolute linear diameters. The main objectives of ourinvestigation were to determine the various diameters of normal and enlarged liver and the criteria ofhepatomegaly in Korean adults using absolute and relative ments. Our cases consisted of 95 clinically normalsubjects and 51 patients suffering from liver disease and diagnosed to have hepatomegaly on abdominal palpationand simple abdomen in the Dept. of Radiology, St, Mary Hospital during the period of 6 months since Jan. 1981. Wemeasured the liver size using 3 linear diameters. And as the reference measurement, the distance from the rightmargin of the liver to the left margin of spleen was also measured. We called this “abdominal transversediameter”(ATD). The results were as follows; 1. The diameters of liver were 13.4±1.6cm, 18.4±2.4cm, 19.2±2.6cmin normal group and 18.8±3.1cm, 23.5±3.0cm, 24.2±3.2cm in hepatomegaly group using midline verticaldiameter(MIVD), maximum vertical diameter (MAVD) and diagonal diameter(DD), respectively. The difference betweentwo groups were statistically very significant in every method(p<0.01). 2. The 99% tolerance limits of liverdiameters were 13.0-13.8cm, 17.8-19.0cm, 18.5-19.9cm in normal and DD, respectively. The midpoints between theupper limit of normal group and the lower limit spectively. These points are warranted to suggest criterias ofhepatomegaly. 3. There were statistical significant difference in the ratio of each diameter to ATD between normaland hepatomegaly group (p<0.01). We called this“hepato-abdominal ratio”. The “hepato-abdominal in hepatomegalygroup using MIVD, MAVD and DD, respectively. 4. The 99% tolerance limits of “hepato-abdominal ratio” were0.43-0.45, 0.59-0.63, 0.62-0.64 in normal group and 0.60-0.62, 0.75-0.77, 0.77-0.79 in hepatomegaly group usingMAVD, MAVD and DD, respectively. The midpoints between the upper limit of normal group and the lower limit ofhepatomegaly group were 0.52, 0.69, 0.70 using MIVD, MAVD and DD, respectively. These points are alsowarranted tosuggest criterias of hepatomegaly.

Syphilitic aortitis, passing out of our mind, is the most common systemic manifestation of late syphilis and is more typically manifestated 10 to 30 years afterward. This diagnosis has been made less frequently in recent decades than in the past, because of public awareness of syphilis and screening program. Treponema pallidum lodge within vasa vasorum, especially ascending aorta cause the histologic changes, which are responsible for the three major forms of symptomatic cardiovascular syphilis, including aortic insufficiency, coronary ostial stenosis, and aortic aneurysm. We experienced a case of syphilitic aortitis with aortic insufficiency and aortic aneurysm in a 48-year-old man presented with progressive dyspnea. Echocardiography, chest CT, and later surgical correction were performed and surgical specimen revealed the histologic finding consistent with syphilitic aortitis. We report this case with a review of the literature.

PURPOSE: The purpose of this study is to evaluate the changing pattern of communication skills of medical students according to length and methods of training. METHODS: We evaluated a 1-week communications training course in 2003, a 1-year course in 2004, and a 1-semester course in 2005 during development of our curriculum. We have conducted the 10-minute CPX on abdominal pain annually since 2002 to assess the clinical performance of medical students who have completed the 3rd year clerkship. We selected CPX videos that were appropriate for assessment. One hundred sixty-four videos were available (1-week didactics: 42 cases, 1-week training: 28 cases, 1-semester training: 50 cases, 1-year training: 44 cases). We developed a 10-item global rating checklist to assess communication skills. A 5-point Likert scale was used to evaluate each item (4-very likely, 0-least likely). Two expert standardized patient (SP) raters evaluated the communication skills of students independently. We analyzed the outcomes based on the training length and methods. The reliability (G coefficient) was 0.825 with 2 SPs and 1 station. RESULTS: The communication skills of students improved with practice and longer training, especially with regard to opening the interview, expressing empathy, understanding the patient's perspective, and preparing for the physical examination. Rapport-building, organization of the interview, understandable explanation, nonverbal communication, active listening and consideration during the physical examination was unchanged between durations of training. The scores for empathetic expression, active listening and understanding the patient's perspective were low across all groups. CONCLUSION: We should concentrate our efforts to improve students' skills in empathetic expression, active listening and understanding the patient's perspective.

OBJECTIVE: In the human body the embryo initially gmws in the fallopian tube which is maintained in an 3-8% O2 concentration environment, and various substances such as growth factors and antioxidants present in tbe tubal fluid assists in maintaining a healthy environment for embryo development. But in IVF programs embryo cultures are conducted in incubators with 21.9% O2 and 5% CO2 condition, and such high oxygen concentrations have been reported to increase the production of oxygen free radicals within the embryo and is detrimental to the growth and development of the embryo. The objective of this study, therefore, is to determine the culture conditions which will decrease oxygen free radical production and thereby minimize the injury to the embryo. METHODS: Six to eight week old ICR strain mice embryos were cultured in 5% or 21.9% O2 conditions and in culture media to which inaement concentrations of superoxide dismutase (SOD) had been and the H2O2 concentration within the embryo, embryo developmental rate, and degree of fragmentation of the embryos was investigated. RESULTS: The control gmup embryos which were cultured in 21.9% O2 condition without addition of SOD showed developmental arrest at the 2-cell stage or fragmentation, while those cultured in 21.9% O2 condition with addition of SOD showed development to the blastocyst stage with deaeased fragmentation. In particular, the blastulation and fragmentation rates were the lowest in the group to which 500 IU/ml of SOD was added, but in the 5% O2 enviranment group many embryos reached the blastocyst stage and with no difference in frapnentation with or without addition of SOD. The HO relative intensity (120.5+/-20.2) within the embryos cultured in 21.9% O2 environment without SOD was significantly higher than that (56.8+/-10.8) of group with SOD (p<0.05). As showing that in the 5% O2 environment group without SOD it was 43.8+/-7.8 and in the group with SOD it was 37.3+/-5.4, the H2O2 concentration within embryos cultured in 5% 02 condition was significantly lower those that of 21,9% 02 environment regardless of SOD addition (p<0.05). CONCLUSION: The optimal oxygen concentration in incubator for mice embryo cultures is that which is similar to the 5% 0 concentration in vivo. When 20% 02 incubators are routinely used, the addition of SOD to the culture media will decrease the H2O2 concentration within the embryos with subsequent improvement in development. The optimal concentration which should be used is thought to be 500 IU/ml. It is suggested that the use of the above method in human IVF-ET programs will lead to improved embryo quality and enhanced pregnancy rates.
