Outcomes of treating hypertension in the elderly: a short commentary on current issues

Because treating hypertension in the elderly so effectively reduces major cardiovascular events, it is vital to diagnose this very common condition early. Much of the hypertension that occurs with aging results from stiffening of the major capacitance arteries, typically marked by high systolic and low diastolic blood pressures. Pulse pressure, derived by subtracting diastolic from systolic values, is a useful index of stiffness, but new noninvasive techniques for measurement of arterial compliance have shown that blood pressures cannot reliably predict the state of the arteries in older people. The Systolic Hypertension in the Elderly Program (SHEP) and the Systolic Hypertension in Europe (Syst-Eur) trial demonstrated that treating hypertension in the elderly with diuretics or calcium channel blockers reduces strokes and cardiac events; these results are also clearly evident in high-risk groups like diabetics. Further analysis of Syst-Eur has suggested that a calcium channel blocker reduces new-onset dementia, while follow-up data from SHEP indicate that a diuretic provides survival and stroke benefits in obese or overweight elderly hypertensives, but not in the lean. In general, comparisons of antihypertensive agents, including diuretics, βblockers, angiotensin-converting enzyme inhibitors, and calcium channel blockers have found similar clinical end point effects. But recently, the Losartan Intervention For End Point Reduction in Hypertension (LIFE) study, performed in patients (average age, 67) with left ventricular hypertrophy and predominant systolic hypertension, showed that the angiotensin receptor blocker losartan was significantly more effective than the β blocker atenolol in reducing such key outcomes as strokes and new-onset diabetes. Even so, careful but effective control of blood pressure in elderly patients, including those over age 80, still remains a critical factor in preventing major cardiovascular events.     

Treating hypertension in the elderly: protagonist viewpoint

Cardiovascular disease is the main cause of serious illness and death in the United States. Increasing age is a strong predictor of cardiovascular events, driven largely by such major conditions as hypertension and diabetes mellitus. Systolic hypertension probably reflects progressive stiffening of large and small arteries; close to 90% of all Americans will have this diagnosis by their 80s. Regardless of age, systolic hypertension is a powerful risk factor for stroke, heart failure, and other cardiovascular outcomes. Treating hypertension in the elderly sharply decreases the probability of these events. Clinical trial evidence does not include patients with stage 1 systolic hypertension (140–159 mm Hg), although the results in stage 2 are so convincing that it is very reasonable (as concluded by national guidelines committees) to extrapolate benefits and recommend treatment to patients in the less-severe group. Whereas evidence of treatment benefits in patients aged 80 years and older is limited, sufficient octogenarians have been studied to confidently assert that strokes, at least, can be prevented. Another potentially important benefit that is yet to be fully confirmed is that treating hypertension in older people may also reduce the incidence of dementia.     

Evaluation of the 24 h effects of the angiotensin II receptor blockers: means to improve cardiovascular outcomes?

Recent research has demonstrated that ambulatory BP is a superior means to predict cardiovascular outcomes in treated patients with hypertension. Ambulatory blood pressure monitoring has been utilized to evaluate the efficacy of all anti-hypertensive drugs including the angiotensin II receptor blockers (ARBs). This paper reviews the relationship of clinic and ambulatory blood pressures to cardiovascular outcomes and the benefits of ARBs to maximize improvement in clinical end-points in patients with hypertension. Clinical trial evidence has demonstrated that ARBs are a preferred class in patients with electrocardiographic evidence of left ventricular hypertrophy, in patients with type 2 diabetes, patients with chronic kidney disease, and in individuals with heart failure who have clinically relevant intolerability to angiotensin converting enzyme inhibitors. In addition, there is increasing evidence from clinical trials that many of the ARBs provide adequate 24 h blood pressure control alone or in combination with other anti-hypertensive agents. We conclude that the combination of event reduction from large-scale clinical trials, adequate 24 h BP reduction, and improved tolerability compared to most other classes of anti-hypertensive agents, make the ARBs a suitable initial treatment for patients with hypertension.     

Prevalence of domestic violence and associated factors among women on a trauma service

BACKGROUND: Despite the increasing recognition of the problem of domestic violence (DV), it has not been studied in surgical populations. METHODS: Eligible patients underwent screening for a recent history of DV and alcohol abuse (AA). Other demographic, health, and injury-related data were also collected. RESULTS: Of 127 subjects entered into the study, 18% screened positive for DV and 21% screened positive for AA. Of those screening positive for DV, 65% screened positive for AA compared with 12% of those screening negative for DV (p < 0.001.) Screening for DV was recommended by a vast majority of subjects, with only 6% of subjects responding that it was not appropriate. CONCLUSION: Both DV and AA have a high prevalence among female trauma patients admitted to trauma centers. Nearly all subjects recommended screening for DV. Screening for DV should be incorporated into the routine care of female trauma patients.     

Blunt renal trauma in children: experience with conservative management at a pediatric trauma center

BACKGROUND: The authors reviewed the outcome for children with blunt renal injury managed with a nonoperative protocol at their pediatric trauma center. METHODS: Fifty-five consecutive children aged 0.5 to 17 years with blunt renal injury managed over a 14-year period were reviewed. All patients were evaluated with computed tomographic scanning. Injuries were graded according to the American Association for the Surgery of Trauma Organ Injury Scale. RESULTS: Forty-eight of 55 children (87%) were successfully managed nonoperatively. Overall, there were 5 grade I, 13 grade II, 18 grade III, 14 grade IV, and 5 grade V injuries. All children with grades I and III injuries were successfully managed nonoperatively. Two (6%) of these children required transfusion. Only four (29%) children with grade IV and three (60%) with grade V injuries required surgical interventions (one nephrostomy, six nephrectomies). Excluding patients with continuing hemorrhage, only 2 (14%) of 14 with high-grade injuries required surgical intervention (1 nephrostomy, 1 nephrectomy). Clearance of gross hematuria correlated with severity of injury and was prolonged in grade IV and V compared with grade I to III injuries (6.8 +/- 2.7 vs. 3.2 +/- 2.1 days, respectively; p < 0.05). Fifty-one children (93%) available for follow-up were normotensive with normal renal function. CONCLUSION: These data support the use of conservative management for all grades in stable children with blunt renal injury. Transfusion requirements, operative rates, and outcome are consistent with other pediatric solid organ injuries.     

RET proto-oncogene mutations affecting codon 790/791: A mild form of multiple endocrine neoplasia type 2A syndrome?

BACKGROUND: In patients with multiple endocrine neoplasia type 2A syndrome, prophylactic thyroidectomy is generally recommended at the age of 5 to 6 years. Whether this recommendation is justified for exon 13 mutations is unknown. METHODS: We analyzed the clinical data from 40 patients harboring RET codon 790/791 mutations (exon 13) who had been treated in 4 specialized centers. RESULTS: Mean age was 35.2 +/- 21.6 years (range, 5.1-69.0 years). Thirteen patients were index patients (mean age, 57.7 +/- 11.3 years), 27 patients were screening patients (mean age, 24.4 +/- 16.5 years). In the index group, pT-category was: T0, n = 2; T1, n = 6; T2, n = 2; T3, n = 1; and T4, n = 2. Lymph node metastases were found in 5 patients and distant metastases in 1 patient. Postoperatively, 69% of index patients were biochemically cured. In the screening group, pT-category was: T0, n = 19; T1, n = 7; and T2, n = 1. Lymph node metastases were found in 2 patients. Postoperatively, 93% of screening patients were biochemically cured. The youngest patient with medullary thyroid carcinoma was 13.8 years, the youngest patient with lymph node metastases was 46.4 years. CONCLUSIONS: Patients with RET codon 790/791 mutations seemed to have a less aggressive clinical course compared with patients with classic multiple endocrine neoplasia type 2A syndrome. Still, index patients had a lower biochemic cure rate in comparison with screening patients. Timely total thyroidectomy including lymph node dissection is warranted.     

Is lumbar disk disease an occupational disease? Scientific background,radiological findings,and medical legal interpretations

AIM: It should be cleared whether or not the interpretation of lumbar disk disease as an occupational disease is justifiable. Which disc changes follow whole-body vibration and can they be distinguished from those which occur constitutionally while aging? METHOD: Orthopedic meta-analysis of epidemiological and occupational studies concerning the influence of whole- body vibration. RESULTS: Reliable studies are rare. Severe methodological problems limit the interpretation of difficult relationships. The role of age when working influences begin as well as the stress and behaviour of exposed persons away from the work-place before and while working with whole-body vibration is not known. There is no study which could be called exact according orthopedic criteria. It is therefore not evident that whole-body vibration causes lumbar disc disease. CONCLUSIONS: After whole-body vibration similar to long term heavy lifting an earlier beginning of disk degeneration in X-ray-studies can be observed. This leads to prevalence differences, which diminish with increasing age. Deviation to the left of the prevalence curve lasts for five to ten years. Whole-body vibration leads to a topographic modification of disk degeneration of the lumbar spine. After long duration exposition an increased amount of spondylotic changes at the thoracolumbar junction and the middle half of lumbar spine can be observed (up to the upper plate of the fourth vertebral body). This can be explained by biomechanic means: whole-body vibration caused by tractor driving and similar long-term exposures leads to traction of the disks of the lower thoracic spine and the upper and middle parts of lumbar spine.     

Paleopathology of the lumbar spine in the early medieval period

AIM: The lumbar spine of people from ancient civilizations can provide a large amount of information about these individuals and their physical condition through paleopathological investigation. METHOD: This study was conducted on a sample of 185 lumbar spines from southwestern Germany dating back in the early medieval period. The skeletons came from the row graves from Nusplingen, Schretzheim, Neresheim, and Pleidelsheim. RESULTS: Examples of congenital malformations, degenerative processes, infections and traumatic diseases were discovered. The most common pathological findings were degenerative changes of the lumbar spine in 24 %. Congenital anomalies and spondylolysis were relatively common in this population. Examples of traumatic injuries and infections of the spine were rare. Metastatic lesions on the vertebral bodies were identified in no case. CONCLUSION: Most diseases of the lumbar column in the ancient inhabitants of southwestern Germany were similar to those that affect the present-day population of that area.
