ABSTRACT
Sphincter of Oddi dysfunction is an underdiagnosed but important clinical condition. It should be considered in the differential diagnosis of biliary pain when the gallbladder sonogram shows no evidence of gallbladder disease. Hepatobiliary scanning (Tc-99m dimethyl iminodiacetic acid) may provide valuable information in the evaluation of these patients and may be helpful in monitoring response to treatment.

In a previous study (resting blood pressure profile, Dinamap) we have confirmed the correlations between blood pressure and left ventricular mass (myocardial hypertrophy being one of the morbidity criteria in Hypertension) and we have demonstrated the absence of significant difference (Fisher's z Test) with the results of ambulatory recordings found in literature. Furthermore, we have showed a weaker correlation between absolute variability (AV) and left ventricular mass (LVM). If indeed there exists a cause-effect relationship between the AV increase and the LVM increase, a relative independence between VA and blood pressures mean (mBP) should still be demonstrated. In order to do that we have used the factorial analysis (main components analysis) with which a small number of independent factors can be isolated from a large number of correlated variables. A resting blood pressure (Dinamap, 8AM-8PM, one reading every 15 minutes) has been recorded among 551 patients (259 females, 292 males; 109 normotensive WHO, 442 hypertensive WHO) and an echocardiogram TM and two-dimensional in order to measure the interventricular septum thickness (IVST), the posterior wall thickness (PWT) and the left ventricular internal diameter (LVID) with which we can calculate the myocardial mass (MM, Devereux formula) and the myocardial mass index (MMI) using the body surface (BS). The blood pressure variables are the means of the recordings (mBP): systolic (mSBP), diastolic (mDBP), mean (mMBP) and their standard deviations (SSD, DSD, MSD) corresponding to the AV. We have studied the heart rate (HR) with its standard deviation (HRSD) and age.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors report 4 cases of Yersinia enterocolitica (Ye) infection in patients with hemoglobin disorders (3 beta thalassemia major, 1 sickle cell anemia). Patients with hemoglobin disorders are particularly vulnerable to Ye infection. Predisposing factors consist mainly of iron overload and deferoxamine therapy; superinfection with HIV may be an additional factor. The diagnosis is performed by identifying patients at risk and by bacteriologic tests (blood and stool cultures, antibody titers). Therapy includes discontinuation of deferoxamine and initiation of an adequate antibiotic therapy.
