Morphological characteristics of human embryos of Carnegie stage 17 were described. The crown rump length of these embryos were 11.7-13.6mm. These embryos were characterized externally by ventrally directed nasal pits, 6 distinct auricular hillocks, finger rays in the hand plate, digital plate at the lower limb bud, herniation of a part of midgut through umbilical cord, and internally by the partial fusion of ventral and dorsal pancreas, prominent nasal sac which is not open to primitive oral cavity, formation of segmental and some subsegmental bronchial buds, branching of metanephrotic pelvis, crescent-shaped lens cavity, and imminent semicircular ducts.

OBJECTIVE: The aims of this study were to analyze the natural history of patients with pseudomyxoma peritonei originated from mucinous ovarian tumor, evaluate clinical and pathologic variables, and review our experience with available therapeutic modalities. METHODS: Six patients were treated for pseudomyxoma peritonei originating from mucinous ovarian tumor at Severance Hospital between 1990 and 1998. The data were collected retrospectively and all charts were reviewed RESULTS: The mean age at diagnosis was 51 years, and most common symptoms were abdominal distension. Pseudomyxoma peritonei was found in association with five mucinous ovarian tumors of borderline malignancy, and one ovarian mucinous adenoma. All patients underwent surgical staging and cytoreduction, three patients received postoperative adjuvant chemotherapy and, of these, two developed recurrence. With respect to survival, all patients were alive, four were alive and free of disease, two were alive with disease at the end point of study. CONCLUSION: Pseudomyxoma peritonei is commonly associated with borderline mucinous ovarian tumors, and is a frequently relapsing and protracted disease. But aggressive and repeated debulking surgery is recommended for long survival.

BACKGROUND: Fluid overload prior to continuous renal replacement therapy (CRRT) is an important prognostic factor. Thus, precise evaluation of fluid status is necessary to treat such patients. In this study, we investigated whether fluid assessment using bioelectrical impedance analysis (BIA) can predict outcomes in critically ill patients requiring CRRT. METHODS: A prospective observational study was performed in patients who were admitted to the intensive care unit and who required CRRT. BIA was conducted before CRRT; then, the ratio of extracellular water to total body water (ECW/TBW) was derived to estimate volume status. RESULTS: A total of 31 patients treated with CRRT were included. There were 18 men (58.1%), and the median age was 67 years (interquartile range, 51 to 78 years). Fourteen patients (45.2%) died within 28 days after CRRT initiation. Patients were divided into 16 with ECW/TBW ≥0.41 and 15 with ECW/TBW <0.41. Survival rate within 28 days was different between the two groups (P = 0.044). Cox regression analysis revealed a relationship between ECW/TBW ≥0.41 and 28-day mortality, but it was not statistically significant (hazard ratio, 3.0; 95% confidence interval, 0.9 to 9.8; P = 0.061). Lastly, the area under the curve of ECW/TBW for 28-day mortality was analyzed. The area under the curve of ECW/TBW was 0.73 (95% confidence interval, 0.54 to 0.92), and this was significant (P = 0.037). CONCLUSIONS: Fluid status can be assessed using BIA in critically ill patients requiring CRRT, and BIA can predict mortality. Further large trials are needed to confirm the usefulness of BIA in critically ill patients.

BACKGROUND: White coat effect (WCE) and white coat hypertension (WCH) are relatively prevalent in clinical situation (20 - 57% of WCH in the hypertensive population). The aim of this study was to analyze the determinant factors of WCE. METHODS: A prospective study was carried out in outpatient clinic in a consecutive hypertensives without receiving pharmacologic treatment. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed following more than two resting blood pressure (BP) determinations carried out with the interval of 1 - 2 weeks by mercury sphygmomanometer. WCE was calculated for systolic and diastolic BP as the difference between a clinic BP (CBP) and an average daytime ambulatory BP (ABP). WCH was defined as;BP in the clinic > or = 140/90 mmHg with a mean daytime BP by ABPM < or =137/< or =89 mmHg. RESULTS: 1) Two hundred thirty-five patients (mean age 49.7 years, females 74%) were studied. Thirty-seven percent in male and forty-six percent in female patients fulfilled WCH criteria. 2) CBP was significantly correlated to daytime ABP (systolic BP;r=.47, p<.001 and diastolic BP;r=.65, p<.001). 3) The magnitude of WCE was greater in the group of WCH (28.9+14.6/19.3+6.9 mmHg) than ambulatory hypertensives (15.1+15.7/13.0+8.2 mmHg) (p<.001). 4) The magnitude of WCE is significantly correlated with female (r2=.12, p<.001) and the stage of CBP according to JNC-V (r2=.23, p<.001) in systolic BP, the stage (r2=.08, p<.001) in diastolic BP, and the stage (r2=.09, p<.001) and weight (r2=.15, p<.01) in mean BP. CONCLUSIONS: The magnitude of WCE in essential hypertension diagnosed at the clinic is significantly correlated with female, the magnitude of clinic BP, and weight.
