CD44 is a hyaluronic acid receptor that exists as a standard 90-kd form (CD44H) as well as several CD44 variants isoforms are produced through alternative splicing. Alternatively spliced variants of the CD44 molecule have been found to be associated with invasive and metastatic potential of cancer cells and poor prognosis in several types of carcinoma. The purpose of the present study is to define the expression of CD44H and CD44v6 in ovarian tumors and to investigate whether the expression of these molecules is associated with adverse prognosis. We evaluated the expression of CD44 isoforms in 58 ovarian tumors by means of immunohistochemistry, and correlated between CD44 expression and the histologic types, tumor grade, peritoneal implants, pseudomyxoma peritonei and FIGO stage. While the CD44H was commonly expressed in ovarian tumors, the CD44v6 was expressed in a minor proportion of serous tumors in comparison with frequent expression of v6 isoform in mucinous tumors. The CD44H expression was significantly higher in stage I/II than in stage III. However, there was no correlation between the expression of CD44 and the presence of peritoneal implants or pseudomyxoma peritonei. These results suggest that CD44H could play an important role in the adhesive function in the lower stage of the ovarian tumor and reduced expression in the higher stage might be related to the metastasis and widespread invasion of ovarian carcinoma cells.

Larval nematodes belonging to genera Ancylostoma, Strongyloides, Rhabditis, Gnathostoma or microfilariae (Onchocerca volvulus)/adult filaria (Loa loa) can invade human skin, each making different lesion. In a 71-year old immunocompetent Koreanman with 23% eosinophilia and elevated serum IgG (2530 mg/dl), a skin biopsy was undertaken for a nodular lesion at abdominal wall. A longitudinal section of a larval nematode was recognized in mid-dermal tunnel surrounded by pseudolymphomatous diffuse lymphoreticular cell infiltration. The larval nematode, 15 um in maximum diameter, had outermost cuticular layer and pale intestinal cells. The nematode section was identified as a filariform larva of Strongyloides stercoralis mainly based on its maximum diameter. In Korea, this is the first description of a cutaneous larval nematode infection. This case did not show quick migration of lesion which is a typical manifestation of classical cutaneous larva migrans.

PURPOSE: The purpose of this study was to investigate perceptions of adequacy and job performance of the nurse assistants' nursing job as evaluated by registered nurses and nurse assistants in geriatric hospitals, and by caregivers from the same hospitals. METHODS: Participants included 62 registered nurses, 57 nurse assistants, and 64 patient caregivers who completed a measurement scale on the job of nurse assistants. Data collection was conducted from October to December, 2015. Data were analyzed using descriptive statistics and one-way ANOVA by IBM SPSS/WIN program version 21.0. RESULTS: There were significant differences by items in perception of adequacy of nurse assistants' nursing job of among the three groups. There was also a significant difference in perception of the nurse assistants' job performance among the three groups. CONCLUSION: For nurse assistants in geriatric hospitals, the Ministry of Health and Welfare needs to develop an appropriate job practice guideline. In addition, there should be periodic courses of retraining and continuing education for nurse assistants.

Large-cell acanthoma is a generally hyperkeratotic, sharply demarcated patch on sun-exposed skin with the outstanding pathologic feature being composed of large, relatively uniform keratinocytes. We describe a case of large-cell acanthoma that involved the skin of the nasal bridge. Patient was a 56-year-old women with a tannish brown patch, 2 cm in size and of 5 years' duration. Controversial issues about nosologic entity of large cell acanthoma are discussed.

PURPOSE: The objectives were to examine following 2 questions related to cognitive profile for the children with Williams syndrome (WS); 1) Is there a significant advantage for verbal IQ over performance IQ in WS?; 2) Is there selective impairment in visuospatial ability in the children with WS? MATERIALS AND METHODS: Five children with WS with the age of 90.86+/-20.73 months were compared with 12 children with Prader-Willi syndrome (PWS) or Down syndrome (DS) with comparable age and IQ. RESULTS: All 5 children with WS showed intellectual disability whose mean scaled scores were 15.71+/-9.27 in verbal subtests and 14.29+/-7.50 in performance subtests, which did not show significant difference. There was no significant difference in the total sum of scaled scores of verbal subtests among WS, PWS and DS. There was no selective impairment in subtests which represented visuospatial tasks for the children with WS. However, the scaled score of object assembly was significantly lower in WS (2.29+/-0.95) compared to that of PWS (4.75+/-2.77; P<0.05). CONCLUSION: The general notion that the children with WS would be relatively strong in verbal function when compared with their overall cognitive function was not observed in this study. The verbal function of the children with WS was not better when compared to the children with DS or PWS. There was no selective impairment of visuospatial function in the children with WS at this age. However, the visuospatial function was significantly low in the children with WS only when compared to the children with PWS.

A 6 year 6month-old boy was admitted with complains of severe spontaneou epistaxis and easy brusability. He was one of five siblings, and two of them died of recurred severe epistaxis at their age of six years. There was no history of bleeding tendency to his antecedents and parents, whose marriage was unrelated. Platelet count and partial thromboplastin time were noraml with prolonged bleeding time, but clot retraction was poor. Platelet adhesion(Salzman method) was decreased and platelet aggregation test showed flat curve with no response to epinephrine and ADP. These tests of other were normal. Diagnosis of thrombasthenia was made with the above history and laboratory results.

There are many hemodynamic and physiologic changes during liver transplantation much more than other surgical interventions. The oxygen delivery and oxygen consumption are af- fected by depressed hemodynamic and metabolic status during the operation. At the lower levels of oxygen present in venous blood, a linear relationship exists between saturation and tension. The use of fiberoptic oximetry system in conventional pulmonary artery flotation catheters has made the bedside application of this relationship of practical value in the continuous assessment of mixed venous oxygen saturation. This study was performed to determine changes in SvO2 and other variables of oxygen kinetics during canine OLT and study the correlation between SvO2 and cardiac output, SvO2 and oxygen consumption and oxygen utilization ratio. The continuous rnixed venous oxygen saturation and cardiac output by SO2/CO computer were monitored and the oxygen delivery, oxygen consumption and oxygen utilization ratio were calculated by arterial and venous blood gas analysis and modified Fick's equation during orthotopic liver transplantation in 20 dogs. The results were as follow as ; 1. There was no significant difference in tissue oxygen extraction between preoperative control and anhepatic phase, while cardiac output were decreased during anhepatic phase. 2. By utilizing centrifugal pump(venovenous bypass) oxygen delivery and oxygen utilization ratio were well maintained even though suppressed the change of oxygen delivery and oxygen consumption during anhepatic phase. 3. There was a significant decrease in SvO2 immediately after declamping the suprahepatic vena cava, whereas the oxygen utilization rate and oxygen consumption following reperfusion were significantly increased than just prior to reperfusion of transplanted liver. 4. A Statistically significant correlation was found between SvO2 and cardiac output, oxygen consumption in all surgical stages except reperfusion(CO;r=0.478, p<0.001, VO2,r=-0. 272, p=0.004), but their correlations were relatively poor. However, there was highly significant correlation among SvO2 and oxygen utilization ratio in all surgical stages(O2UR; r=- 0.834, P<0.001). In conclusion, continuous monitoring mixed venous oxygen via a fiberoptic pulmonary catheter could be used as the index for evaluation of hemodynamics and oxygen kinetics during canine OLT, but further research should be performed to determine whether these measurements indicate viability of the grafted liver.
