The use of alginate impression materials today is prevalent because of its efficiency and simplicity in clinical settings. Unfortunately, the simplicity of the procedure tends to lull the dentist into a sense of well-being, and lead him into using careless or sloppy technique. Alginate impression materials are used to fabricate diagnostic and preliminary casts, and the final cast. Incorrect use of this material is known to affect the accuracy of the final prosthesis. The purpose of this study was to compare the effect of different mixing methods of alginate impression material and tray adhesive on the accuracy of the stone cast produced by each method. A total of 30 stone casts were produced by using 3 different types of mixing methods (10 stone cast for each mixing method, respectively) The first method utilized an automatic-mixing machine to mix alginate while the second method was carried out manually, strictly following manufacturer's instructions. The third method also involved manual mixing, but did not follow the manufacturer's instructions and was done in a random fashion. Also, 20 additional stone casts were produced by using alginate with or without tray adhesives were included in the study to evaluate effects of tray adhesives on the accuracy of alginate impression. 10 stone casts were produced by adding tray adhesives to the interior surface of the impression tray prior to taking the impression. The other 10 excluded this step. A total of 50 stone casts were analyzed by the three-dimensional measuring machine to measure and compare the dimensional changes of the impression material of each group. The results are as follows. 1. No significant difference was found between the automatic mixing group and the manually-mixing group(p>0.05). 2. For the group that followed manufacturer's instructions, less dimensional changes were recorded than the group that didn't in measuring distance d4(p<0.05) 3. The group that used tray adhesives showed less dimensional changes(p<0.05). The findings revealed that mechanical methods of mixing alginate impression materials had little influence on dimensional changes. However, it is proven that following manufacturers instructions in alginate impression taking is an important step in acquiring accurate impressions and tray adhesives may play an important role in enhancing the results.

We described a giant chroioangioma of the placenta that caused premature rupture of membranes at 31 weeks of gestation in a 31-year-old primiparous woman and a subsequent neonatal death of the baby. The placental mass, weighing 820 gm and measuring 21.5x15x4.5 cm, was easily shelled out from a edematous 1280 gm-placenta. The mass had a thin fibrous capsule and a solid fibromatous appearance. The infant, weighed 2175 gm, appeared edematous oon the whole body and had Apgar scores of 4 and 5 at 1 and 5 minutes respectively. The baby expired 4 days after birth due to high output cardiac failure and respiratory failure. Postmortem examination revealed markedly dilatated umbilical vein, inferior vena cava and right atrium with patent froamen ovale, congestive hepatosplenomegaly, pulmonary hemorrhages, and meconium aspiration pneumonia. Microscopically, the mass revealed a variety of histologic patterns, reflecting entire spectrums of villous vasculogenesis from loose myxomatous connective tissue and undifferentiated hemangioblastic cell nests to well-developed capillaries with hematopoietic cells in the lumen.

BACKGROUND: The relationship between type II diabetes and congnitive function has been explored in several studies. But the result was controversial. The purpose of the study was to determine whether diabetes mellitus in older patients(>or=65 years) is assiciated with cognitive dysfunction and to discover the related factors with th cognitive dysfunction. METHOD: Twenty patients with type 2 diabetes and twenty subjects with non-diabetes are studied with cognitive function test at Hwachun health center and county hospital. Cognitive function was assessed using Mini-Mental State Examination and Clock Drawing test and the score was analyzed. The diabetes groups were subdivided with duration of diabetes, HbAlc, chronic diabetic complications and then analyzed. RESULTS: A total of 6(30%) diabetic subjects scored below 24 on mini-mental state examination, compared with 3(15%) of controls(p=0.2560). The mean socres were 20.1+/-2.7 and 19.0+/-3.5 respectively. Clock drawing test demonstrated that 13(65%) diabetic subjects inconectly placed the numbers and hands, compared with 7(35%) of controls(p=0.0578>0.05). The duration of diabetes mellitus, HbAlc, chronic diabetic com- plications were not associated with cognitive dysfun- ction among diabetic subjects. CONCLUSIONS: The study showed that type 2 diabetes mellitus in the elderly is not associated with cognitive dysfunction, but further study should be done.

PURPOSE: The aim of this study was to compare conventional scissors and Harmonic Scalpel(R) hemorrhoidectomy. METHODS: Two hundred and five patients were prospectively assigned to two groups in the consecutive order. The group was divided into Group A (Harmonic Scalpel(R) excision; n=101) and Group B (conventional scissor excision; n=104). All other aspects of surgery and anesthesia were standardized. Intramuscular opiate was available on demand during the postoperative period, and analgesic requirements were also recorded. All patients noted their pain on a daily basis using a visual analogue scale (0=no pain; 10=worst pain). The length of hospitalization, operative time and postoperative complications were also analyzed. RESULTS: The operative time was 16.6 +/- 0.9 minutes 25.3 +/- 0.8 minutes in Group A and B, respectively (p<0.01). Length of hospital stay was 4.1 +/- 0.1 and 4.5 +/- 0.1 days (p<0.05). Pain scores in the group A were significantly lower than in the group B (p<0.01). Analgesic requirements were also significantly less in group A (p<0.05). Postoperative complications, such as urinary retention, fecal impaction and skin tags were rarer in group A. One patient in group A and two patients in group B developed secondary hemorrhage, but no patient had anal stricture. CONCLUSIONS: The Harmonic Scalpel(R) excision significantly shortens the operative time for hemorrhoidectomy with less blood loss and postoperative pain without remarkable early or late postoperative complications.
