Self-measurement and automatic measurement in ambulatory blood pressure monitoring

INTRODUCTION: There are strictly determined conditions under which blood pressure measurement should be done and diagnosis of hypertension made. The first BP measurement should be performed on both arms. If there is a difference, controls should be made on the side on which the pressure is higher. In older persons the Osler manoeuvre should be made in order to exclude pseudohypertension. One should be aware that in hospitalized patients the BP is lower due to the bed rest itself. SELF-MEASUREMENT OF BLOOD PRESSURE: It seems that erroneous interpretation of blood pressure fluctuation and the tendency for self-medication by patients are the most important shortcomings of blood pressure self-monitoring. According to the World Hypertension League instructions, the BP self-measurement is not recommended for patients obsessed by the disease, neurotic and anxious persons, old subjects and in those who are physically handicapped. Since the diagnosis of hypertension should be made by the physician in office conditions, in our opinion the evolution of the disease and effects of treatment should be estimated under the same conditions. BLOOD PRESSURE AMBULATORY MONITORING: Ambulatory 24-hour monitoring is of a considerable diagnostic, therapeutic and prognostic importance over the casual or self-measurement, but one should be familiar with some peculiarrities of this method. Due to the adaptation to the device, the values of BP on the first measurement, particularly during the first 5 hours are significantly higher than during the subsequent measurements. In some subjects the values during the night may be higher due to the sleeping disturbances caused by the procedure. Differentiation between dippers and non-dippers has some prognostic and therapeutic implications. White coat hypertension may be successfully established by the ambulatory measurement. There is also a correlation between the BP variations and the myocardial mass. The trough:peak ratio may contribute to the estimation of efficiency of a certain drug. There are particular indications for ambulatory BP monitoring: the differences between the office and home values of BP are considerable; borderline hypertension; hypertension without signs of the target-organ damage; transitory hypertension of hypotension; syncopal attacks; vague symptoms in hypertensive patients; atypical or nocturnal angina; evaluation of the efficiency and duration of drug action; for research purposes.     

Effects of 24-hour ambulatory blood pressure monitoring on daily activities.

Compared the self-monitored activities, locations, and postural positions of 28 hypertensives while they wore an alarm watch and then while they wore a 24-hr ambulatory blood pressure monitor (ABPM) to see if wearing the ABPM led to alterations in behavior. Significant differences were found in frequency of being at home or in miscellaneous settings; in standing and reclining positions; and in mental, physical, and miscellaneous activities between the 2 occasions. For the most part, differences were in the direction of showing lower overall blood pressure while wearing the ABPM than would have been found at the same time while wearing the watch.

Left ventricular hypertrophy and ambulatory blood pressure monitoring in chronic renal failure

BACKGROUND: Left ventricular hypertrophy (LVH) is both common and an important predictor of risk of death in end-stage renal failure (ESRF). In mild to moderate chronic renal failure (CRF), the timing of onset of LVH and the factors involved in its initial development have not been fully elucidated. The present study was undertaken to examine the prevalence and potential determinants of echocardiographically determined LVH in this connection, and to compare 24-h ambulatory blood pressure (BP) recordings with BP measured at a previous clinic visit. METHODS: From a cohort of 120 non-diabetic patients who had been attending a nephrology clinic, 118 agreed to participate in the study. Of these we selected for analysis 85 stable patients (37 male). Patients with known cardiovascular disease, those with a history of poor compliance with antihypertensive medication, and those in whom such medication had been changed in the previous 3 months were excluded. Clinic BP, 24-h ambulatory BP, echocardiography, body mass index (BMI), serum creatinine (SCr), creatinine clearance (CrCl), haemoglobin (Hb), fasting cholesterol (CHOL), triglyceride TRIGL), plasma glucose, calcium (Ca), phosphate (PO4), alkaline phosphatase (ALK PHOS), parathyroid hormone (PTH) concentrations, and 24-h urinary protein were assessed in all patients. Seventy-seven per cent were on antihypertensive medication. RESULTS: LVH was detected in 16% of patients with CrCL > 30 ml/min, and 38% of patients with CrCl < 30 ml/min. By stepwise regression analysis, ambulatory systolic BP (P < 0.0001), male gender (P < 0.0001), BMI (P < 0.0002), and Hb concentration (P < 0.002) were the only independent determinants of left ventricular (LV) mass. Nocturnal systolic BP (P < 0.02) was the main determinant of LVH in the group of patients with advanced CRF. The correlation between left ventricular mass index (LVMI) and mean 24-h ambulatory systolic BP (r = 0.52, 95% confidence interval 0.50-0.54) was statistically significantly stronger than with outpatient systolic BP (r = 0.25, 95% confidence interval 0.23-0.27). The same was true for the correlation between LVMI and mean 24-h ambulatory diastolic BP (r = 0.42, 95% confidence interval 0.40-0.44), and outpatient diastolic BP (r = 0.22, 95% confidence interval 0.20-0.24). CONCLUSIONS: Twenty-four hour ambulatory BP recording and echocardiography are required for accurate diagnosis of inadequate BP control and early LVH in patients with chronic renal impairment, independent determinants of which are hypertension, male sex, BMI, and anaemia.     

Twenty-four-hour ambulatory blood pressure and heart rate monitoring in combat-related posttraumatic stress disorder

This study examined the cardiovascular correlates of posttraumatic stress disorder (PTSD) in Vietnam combat veterans using 24-hr ambulatory blood pressure and heart rate monitoring. Veterans with PTSD (n = 11) exhibited significantly higher heart rate and diastolic blood pressure across the 24 hr than veterans without PTSD (n = 7) (80.8 vs. 71.9 bpm, and 80.1 vs. 71.5 mm Hg, respectively). Heart rate during sleep was also significantly higher among veterans with PTSD, compared to veterans without PTSD (71.0 vs. 62.7 bpm). These results, based on a more naturalistic measurement methodology used outside the laboratory, support an association between PTSD and increased chronic cardiovascular arousal.     

A consistent reference frame for ambulatory blood pressure monitoring is found in different populations

This study investigated the consistency of a reference frame for ambulatory pressure monitoring, which using various approaches was determined in two different populations. The two reference groups were 718 subjects randomly selected from the population and 895 bank employees. The reference values derived in these two groups were subsequently tested in 591 untreated hypertensive patients. The ambulatory pressures equivalent to a conventional pressure of 140 mmHg systolic and 90 mmHg diastolic were calculated by regression analysis in all subjects. In addition, in subjects who were normotensive by conventional sphygmomanometry, the mean +2 and +3 standard deviations and the 90th, 95th and 99th percentiles of the ambulatory measurements were determined. The distributions of the ambulatory measurements were similar in the two reference groups and the aforementioned parameters therefore agreed within 4 mmHg in the two populations. There was considerable overlap in the ambulatory pressures between the two reference groups and the hypertensive patients. Classification of the patients according to the means +3 standard deviations and the regression limits gave the same results because in both reference groups these boundaries approximated to each other within 1 mmHg. For the 24 h pressures in the population sample these boundaries were 140 mmHg systolic and 88 mmHg diastolic. Of the patients with systolic hypertension (> or = 160 mmHg on conventional measurement), 39% had a 24 h systolic pressure of < 140 mmHg and of those with diastolic hypertension (> or = 95 mmHg), 44% had a 24 h diastolic pressure of < 88 mmHg; if the corresponding boundaries derived in the bank employees (143/90 mmHg) were applied, these proportions were 47% and 44%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)     

Efficacy of benazepril monotherapy in moderate essential hypertension studied by automatic ambulatory blood pressure monitoring

Authors examined the effects of benazepril, regarding the length of effectiveness by ambulatory blood pressure monitoring (ABPM), drug tolerable, and the compliance of patients in mild to moderate essential hypertension. 14 patients were treated with benazepril monotherapy. Six of them were newly diagnosed, and the rest had already been treated for hypertension. At the start, after six and 12 weeks, 24-hour monitoring was performed. Casual blood pressure (BP) measurements and detection of side-effects were also performed at 3rd and 9th-week. Prior the study the average daytime BP measured by ABPM was 149.1 +/- 7.7/96.6 +/- 4.7 mmHg. 10 mg of benazepril was first administered in the morning. By the end of the sixth week the average BP was significantly decreased (daily average: 139.1 +/- 9.9/88.2 +/- 7.6 mmHg). The daytime diastolic average BP of 8 patients was lower than 90 mmHg and the other's daily dose was raised to 20 mg. During the 12th-week we found optimal tension in 11 patients, while in two others there was also a significant decrease. The daily average BP was 134.7 +/- 7.5/85.6 +/- 6.6 mmHg. In comparison the data at the beginning of the study here was significant decrease in the 24-hour, daytime and night-time BP, in the hypertension time-index and the hyperbaric impact, both in systolic and diastolic levels. During the 12th-week period the diurnal index was unchanged. The early morning BP decreased by the end of the 3rd month from 148.6 +/- 14.1/98.5 +/- 11.7 mmHg to 135.2 +/- 13.5/93.4 +/- 11.2 mmHg. Sustained side-effect did not occur. The patient's compliance to benazepril was excellent. Authors conclude that benazepril monotherapy lowered in 92.8%, and normalized in 78.5% the blood pressure of patients suffering from mild to moderate essential hypertension. The unchanged diurnal index, and the decrease in the early morning blood pressure suggest the 24-hour effect of benazepril.     

Normal values for ambulatory blood pressure and differences between casual blood pressure and ambulatory blood pressure: results from a Danish population survey

Oncogenic forms of the Abl and Src tyrosine kinases trigger the destruction of the Abi proteins, a family of Abl-interacting proteins that antagonize the oncogenic potential of Abl after overexpression in fibroblasts. The destruction of the Abi proteins requires tyrosine kinase activity and is dependent on the ubiquitin-proteasome pathway. We show that degradation of the Abi proteins occurs through a Ras-independent pathway. Significantly, expression of the Abi proteins is lost in cell lines and bone marrow cells isolated from patients with aggressive Bcr-Abl-positive leukemias. These findings suggest that loss of Abi proteins may be a component in the progression of Bcr-Abl-positive leukemias and identify a novel pathway linking activated nonreceptor protein tyrosine kinases to the destruction of specific target proteins through the ubiquitin-proteasome pathway.     

Evaluation of a new ambulatory blood pressure device

We assessed the OSCILL-IT ambulatory blood pressure (BP) recorder (FIGI sr1, Rome, Italy) according to the performance criteria set out by the British Hypertension Society (BHS) protocol. The OSCILL-IT is a portable, noninvasive recorder that uses a process that correlates systolic, mean, and diastolic areas, identified on the oscillations, to the cuff absolute pressure. According to the recommendations of BHS, a large heterogeneous population (100 subjects: 52 men aged from 19 to 79--median 44 and 48 women from 19 to 74--median 54) was recruited in order to assess accuracy and to analyze, in addition, the effects of observer agreement and BP level on the observer-device differences. With reference to BP level, we suggest also a new graphic approach. Four sets of sequential, same arm, comparative BP measurements were obtained, performed by the OSCILL-IT recorder and two skilled clinicians using a mercury column, for each subject. We used a linear combination for the statistical evaluations. We confirmed the observer agreement through the frequency distribution of BP as a function of the observer and through the differences between observers. We compared OSCILL-IT with sphygmomanometric readings: the differences were not significant. A visual inspection, with the addition of regression lines, showed that there were no variations in differences at the changing of BP level. The difference between observers and OSCILL-IT was 0.2 +/- 5.3 mm Hg and 0.2 +/- 5.8 mm Hg both for systolic BP (SBP) and diastolic BP (DBP). The level of agreement, according to BHS criteria, showed that 64% of all systolic and 70% of all diastolic readings obtained by the OSCILL-IT were within 5 mm Hg of the sphygmomanometric determinations. Therefore, the grade is C for SBP, even if 93% of SBP and 95% of DBP obtained by the OSCILL-IT were within 10 mm Hg of the sphygmomanometric determinations. These analyses demonstrate that the OSCILL-IT satisfies the accuracy parameters and the additional linear regression yields graphics more immediate.     

Twenty-four-hour ambulatory blood pressure evaluation of antihypertensive agents

EVALUATION OF A SMOOTH BLOOD PRESSURE RESPONSE TO TREATMENT: Smooth or uniform blood pressure control is an obvious goal of antihypertensive therapy, but it is difficult to assess by the traditional clinic blood pressure measurements. Ambulatory blood pressure monitoring is therefore increasingly being used to evaluate new antihypertensive drugs and to assess the adequacy of treatment. The use of ambulatory blood pressure monitoring is based on two assumptions: that treatment must be continuously optimal, and that more frequent blood pressure measurements during treatment, particularly at different times and during various types of activity and mental states, may lead to a more accurate assessment than infrequent measurements in the clinic. When ambulatory blood pressure monitoring is used, the effect of a given antihypertensive agent or of a given antihypertensive regimen can be tested on the average blood pressure values over 24 h, or on day- or night-time values. The actual verification of the achievement of a uniform reduction of blood pressure throughout the 24-h time span can be achieved by comparing 24-h blood pressure profiles before treatment and during treatment. The so-called trough: peak ratio is generally used in an attempt at a more quantitative assessment of smooth control. Recently, we have developed the Smoothness Index, defined as the ratio between the mean hourly change in blood pressure (calculated over the 24-h period), divided by the standard deviation of these hourly changes. We have some indication that this may be a more accurate measurement of smooth blood pressure control under therapy than trough: peak ratios. TWENTY-FOUR-HOUR BLOOD PRESSURE CONTROL BY IRBESARTAN: Ambulatory blood pressure assessments are important during the clinical testing of new antihypertensive agents. Our group recently performed a multicenter study to compare the anti-hypertensive effect of three irbesartan dose regimens (75 mg once a day, 150 mg once a day, 75 mg twice a day) and placebo as measured by 24-h ambulatory blood pressure monitoring and confirmed by office blood pressure measurements. All irbesartan regimens were significantly more effective than placebo. Irbesartan at 150 mg once a day provided clinically significant and sustained blood pressure reductions over a full 24 h and had the highest trough: peak ratio and Smoothness Index. No additional benefit was observed with twice-daily dosing using irbesartan at 75 mg compared with a single daily at 150 mg. Therefore irbesartan at a single daily dose of 150 mg offers real efficacy with the potential for greater ease of administration compared with twice-daily antihypertensive therapy.     

Continuous ambulatory measurement of blood pressure in children--personal experience

Ambulatory blood pressure monitoring (ABPM) during normal daily activities and during night, when the patient is asleep, is a new method of measuring blood pressure (BP) in children, used for better diagnosis and treatment of hypertension. Compared to casual BP measurements, it documents normal daily BP variations, BP during sleep, the influence of emotional and physical stress on BP and is a better predictor of hypertension associated with end-organ damage. However, the experience in ABPM in children is still limited. In our country ABPM has been used since recently, and first results are referred to children with end-stage renal failure. SUBJECTS AND METHODS: ABPM was performed in two groups of children: group A consisted of 61 children, aged 14.3 +/- 2.9 (mean +/- SD) yrs in whom intermittent outpatient BP measurements (for at least 3 months) suggested the diagnosis of hypertension (according to the data of Second Task Force); group B consisted of 52 patients (pts), aged 12.8 +/- 4.6 yr with renal disease. Four pts from group A (6.6%) and 20 pts from group B (38.5%) received antihypertensive therapy (captopril, nifedipine, furosemide and propranolol ). All children from group A and half of the children from group B had normal renal function. Eighteen pts from group B were on chronic haemodialysis (34.6%). Blood pressure was recorded during a 24-hour period except in haemodialyzed pts (48 h) (Table 1). Results of BP measurements are presented as the mean values of BP during a 24-hour period, during normal daily activities and during sleep. We used the age- and gender-appropriate 95th percentile from the Task Force Study as the daytime upper-limit of normal and 10% lower for the upper-limit at night. According to BP load (the percentage of BPs exceeding the upper limits of normal for age), children were assumed to have mild-to-moderate hypertension (BP load between 20% and 40%) or severe hypertension (BP load more than 40%). The success of antihypertensive therapy was evaluated after 1-3 months in 11 pts (twice in 10 pts and three times in one pt). RESULTS: In group A 39.4% of pts were normotensive and 36.1% were without antihypertensive therapy, 58.4% of normotensive and 40.5% of hypertensive pts had blunted circadian BP rhythm (nocturnal BP reduction of less than 10% of diurnal values) (Graph. 1). In group B 38.5% of pts were normotensive and 27% were without antihypertensive therapy. In the group of normotensive pts alteration of circadian BP rhythm was found in 40% of pts with normal renal function, 80% of pts with chronic renal failure and in 100% of pts with terminal renal failure, while in the hypertensive group, altered circadian BP rhythm had 68%, 100% and 92% of pts, respectively (Graph 2). Mild-to-moderate hypertension had 54% of hypertensive pts from group A and 37.5% of hypertensive pts from group B. Severe hypertension was more frequent in group B (62.5%) comparing to group A (46%). The effectiveness of antihypertensive therapy was assessed in 11 pts. In 69.2% of pts BP became normal or was significantly decreased, in 23.1% of pts BP was not changed and 7.7% of pts had higher values of BP. DISCUSSION: ABPM is very useful for diagnosing white coat hypertension. Like other authors, we have pointed out that more than one third of pts who were hypertensive according to usual BP measurements had normal 24-hour BP and we classified them as white coat hypertensives. More than a half of the pts had blunted circadian BP rhythm, and as it is not certain whether they will become hypertensive in adulthood they should be periodically controlled. There are several proofs that results of ABPM have a better correlation with hypertensive end-organ damage; therefore ABPM is used for assessing the severity of hypertension. In our former work, we showed excellent correlation of BP with left ventricular mass index in children with end-stage renal failure. (ABSTRACT TRUNCATED)     

Acrophase amplitude of ambulatory blood pressure decreases in migraineurs

Ambulatory blood pressure was recorded and analyzed in 13 migraineurs during headache-free periods and in 11 healthy subjects. Systolic blood pressure, mean blood pressure, diastolic blood pressure, pulse pressure, and pulse rate were recorded for 48 hours (three times every hour from 6 AM to mid-night, once an hour at night). Circadian variation of blood pressure was analyzed using single cosinor analysis and group mean cosinor analysis methods. Single cosinor analysis identified significant circadian rhythm of systolic blood pressure in 10 of 11 control subjects (90.9%) and 5 of 13 migraineurs (38.5%, P < 0.02 versus controls, Fisher's exact test). Incidences of significant circadian rhythm of mean blood pressure and diastolic blood pressure were 100% and 100% in controls, 46.2% and 53.8% in the migraineurs (P < 0.01, P < 0.02 versus controls). Incidences of significant rhythm of pulse pressure were 36.3% in controls and 38.5% in the migraine group (difference was not significant). Group mean cosinor analysis identified significant circadian rhythm in both the migraine group and the controls. The MESOR (midline estimating statistic of rhythm) values of systolic, mean, and diastolic blood pressures showed no significant differences between the migraine group and the controls. Acrophase amplitudes of systolic, mean, and diastolic blood pressure were 4.2, 5.2, and 5.9 mm Hg in the migraine group, respectively; and 7.2, 7.3, and 7.5 mm Hg in the controls, respectively. These amplitudes of systolic, mean, and diastolic blood pressures in the migraine group were significantly smaller than those in the controls. These data suggest that some migraineurs lose or alter their circadian blood pressure rhythm. Evaluating migraineurs as a group, significant circadian rhythm of blood pressure can be identified and oscillation amplitudes of blood pressures are decreased. The present results suggest that migraineurs may be subject to dysfunction of the circadian rhythm generator and the autonomic nervous system. Possible involvement of serotonergic projections from the raphe to the suprachiasmatic nuclei of the hypothalamus in migraine is discussed.     

Nifedipine gastrointestinal therapeutic system versus nifedipine coat-core: comparison of efficacy via 24-hour ambulatory blood pressure monitoring

OBJECTIVE: To assess the comparable efficacy and adverse effect profile of two extended-release preparations of nifedipine--gastrointestinal therapeutic system (GITS) and coat-core (CC)--in patients with mild-to-moderate hypertension. DESIGN: Single institution, single-blind, prospective study. SETTING: Dwight David Eisenhower Army Medical Center, Fort Gordon, GA. PATIENTS: Ninety-one patients who were taking nifedipine GITS as a sole antihypertensive agent were randomized to receive either GITS or CC. After 3 weeks, 24-hour ambulatory blood pressure monitoring was conducted and an adverse effect questionnaire was administered. The patients were then crossed over to the other treatment arm and monitoring was repeated after 3 weeks. MEASUREMENTS: Mean blood pressure, heart rates, and the percentage of readings exceeding 140 mm Hg systolic and 90 mm Hg diastolic were compared for the 24-hour period. Additionally, mean blood pressures at 4-hour intervals after drug administration and heart rate during the first 8 hours of the dosage interval were compared. RESULTS: Ninety-one patients enrolled, 79 completed the study, and 62 patients were included in the efficacy analysis. A statistically significant difference (p = 0.020) was shown only in the last 4-hour systolic blood pressure. However, this difference was small (122 +/- 15 mm Hg with GITS vs. 126 +/- 14 mm Hg with CC). There was no difference in the percentage of readings exceeding 140 mm Hg systolic or 90 mm Hg diastolic. Neither dosage nor treatment order had an effect on the results. Adverse effects were reported with a greater frequency during CC therapy (40 with CC vs. 22 with GITS; p = 0.006), but were generally transient. Discontinuation of the drug was necessary in 3 patients during the CC cycle. CONCLUSIONS: GITS and CC demonstrated clinically equivalent antihypertensive efficacy in the study population. The CC produce may have a higher rate of adverse effects, but drug discontinuation was uncommon.     

White coat effect detected using self-monitoring of blood pressure at home: comparison with ambulatory blood pressure

The objective of the study was to investigate whether home blood pressure (HBP) is a reliable alternative to ambulatory blood pressure (ABP) for the detection of the white coat effect (WCE). Hypertensive patients were randomized to measure HBP for 2 weeks or ABP for 24 h. The alternative measurement was then performed. Clinic blood pressure (CBP) was measured in the beginning and end of the study. Subjects with a difference of > or = 20 mm Hg systolic or > or = 10 mm Hg diastolic BP between CBP and awake ABP or CBP and HBP, were classified as clinic reactors. A total of 189 patients completed the study (79 on stable antihypertensive treatment). There was no difference in the magnitude of WCE assessed using the ABP or the HBP method (mean discrepancy, systolic BP: -1.5 +/- 11.7 mm Hg, 95% CI -3.2, 0.2; diastolic BP: 0.9 +/- 7.0, 95% CI -0.1, 1.9). A strong association existed between WCE calculated using the HBP or the ABP method (r = 0.64/0.59 systolic/diastolic, P < .001). The proportion of patients classified as clinic reactors was identical using the HBP or the ABP method (25.9%). Agreement between methods in the classification of clinic reactors was found in 147 patients (78%). The sensitivity and specificity of the HBP method to classify correctly clinic reactors (ABP method used as the standard) were 57% and 85%, respectively, whereas its positive and negative predictive value were 57% and 85%. These results indicate that HBP is not appropriate as an alternative to ABP diagnostic testing in the detection of WCE. Nevertheless, HBP appears useful as a screening test for the detection of this phenomenon.     

Job strain and ambulatory blood pressure among female white-collar workers

To evaluate the nutritional, metabolic and immune effects of dietary arginine, glutamine and omega-3 fatty acids (fish oil) supplementation in immunocompromised patients, we performed a prospective study on the effect of immune formula administered to 11 severe trauma patients (average ISS = 24), 10 burn patients (average % TBSA = 48) and 5 cancer patients. Daily calorie and protein administration were based on the patient's severity (Stress factor with the range of 35-50 kcal/kg/day and 1.5-2.5 g/kg/day, respectively) Starting with half concentration liquid immune formula through nasogastric tube by continuous drip at 30 ml/h and increasing to maximum level within 4 days. The additional energy and protein requirement will be given either by parenteral or oral nutritional support. Various nutritional, metabolic, immunologic and clinical parameters were observed on day 0 (baseline), day 3, 7, and 14. Analysis was performed by paired student-t test. Initial mean serum albumin and transferrin showed mild (trauma) to moderate (burn and cancer) degree of malnutrition. Significant improvement of nutritional parameters was seen at day 7 and 14 in trauma and burn patients. Significant increase of total lymphocyte count (day 7, P < 0.01), CD4 + count (day 7, p < 0.01), CD8 + count (day 7, p < 0.0005 & day 14, p < 0.05), complement C3 (day 7, p < 0.005 day 14, p < 0.01), IgG (day 7, and 14, p < 0.0005), IgA (day 7, p < 0.0005 & day 14, p < 0.05), in all patients. C-reactive protein decreased significantly on day 7 (p < 0.0005) and day 14 (p < 0.005). 3 cases of burn wound infection, one case of UTI and one case of sepsis were observed. Two cases of hyperglycemia in burn, 3 cases of hyperbilirubinemia in trauma, 10 cases of elevated LFT (5 trauma/5 burn), and one case of hyponatremia in cancer patients were observed. Two cases of nausea, 4 cases of vomiting, 5 cases of diarrhea (< 3 times/day), 2 cases of abdominal cramp, 1 case of distension were observed. The feeding of IMMUNE FORMULA was well tolerated and significant improvement was observed in nutritional and immunologic parameters as in other immunoenhancing diets. Further clinical trials of prospective double-blind randomized design are necessary to address the so that the necessity of using immunonutrition in critically ill patients will be clarified.     

Office and ambulatory blood pressure in patients with craniomandibular disorders

To assess the physiologic response to daily life stress in patients with craniomandibular disorders (CMD), office and ambulatory blood pressure and heart rate were studied in 25 female patients and 25 controls. Significant differences (p < 0.05) were found between the groups for heart rate before the clinical examination and that in the patient group when compared before and after the clinical examination. Higher values were found for mean daytime systolic and diastolic blood pressure in the control group compared with the patient group (p < 0.05). The mean number of systolic blood pressure > or = 140 mmHg during 24 h and daytime was significantly higher (p < 0.05) in the control group than in the patient group. In this study the CMD patients with muscular diagnosis were not more stressed than healthy subjects in the daily activities as evaluated by ambulatory blood pressure measurements.
