Thickening of the gallbladder wall in ascites.

The thickening of the gallbladder wall in patients with ascites is commonly related to hypoalbuminemia and/or portal hypertension. To evaluate the pathogenetic role of these two factors, we correlated gallbladder wall thickness (GBWT) with the albuminemia and the serum-ascites albumin gradient (SAAG), an index of portal hypertension, in 47 patients with ascites caused by cirrhosis of the liver or abdominal malignancy. We found a thickened gallbladder wall in 30/47 patients. The correlation between GBWT and SAAG was 0.64 (n = 47 p less than 0.001). No correlation was found between GBWT and albuminemia (r = 0.04). We suggest that the sonographic finding of ascites and gallbladder wall thickening should be considered a valuable sign of transudative ascites and of portal hypertension whatever its cause.

Comparison between casual blood pressure and ambulatory blood pressure monitoring parameters in healthy and hypertensive adolescents.

Casual blood pressure measurements were compared with mean ambulatory blood pressure values during wakefulness and sleep in 45 normotensive and 30 hypertensive adolescents of both sexes aged 10-18 years. Two sets of auscultatory casual blood pressure were obtained, one in a pediatric office setting (office blood pressure), performed by the physician, and one in the ambulatory blood pressure monitoring (ABPM) unit, performed by a trained nurse, prior to the initiation of ABPM (pre-ABPM blood pressure). In normotensive and hypertensive subjects of both sexes, the mean office systolic blood pressure (SBP) was lower than the mean pre-ABPM SBP, and the mean office diastolic blood pressure (DBP) was lower than the mean pre-ABPM DBP. In normotensive participants, the mean pre-ABPM SBP/DBP was lower than the mean ABPM SBP/DBP while awake, the mean ABPM SBP/DBP during sleep being lower than the mean ABPM SBP/DBP values while awake and the mean pre-ABPM SBP/DBP. No statistical difference was demonstrated between the mean office SBP and the mean ABPM SBP during sleep, the mean ABPM DBP during sleep being lower than the mean office DBP. The hypertensive adolescents presented a blood pressure profile similar to that of the normotensive group, albeit shifted upwards, with no significant difference between the mean pre-ABPM SBP and the mean ABPM SBP while awake but a higher mean pre-ABPM DBP than mean ABPM DBP while awake. This study suggests that, by evaluating the casual blood pressure in different environment/observer situations, the power of casual blood pressure to predict inadequate blood pressure control, manifested as abnormal ABPM parameters, can be enhanced. Our data indicate ABPM to be the method of choice for the early diagnosis and adequate follow-up of adolescent hypertension.
