Gram stain microbiological pattern of upper extremities suppuration at Baptist Medical Centre, Ogbomoso Nigeria: a fifteen month review.

Sixty-eight (68) patients with serious upper extremity suppurative infections, presenting within a period of fifteen (15) months, were prospectively studied clinically, Gram stain of aspirates/pus were performed, specimen cultured, planted, and where indicated glucose levels and haemoglobin genotype determined. Half of the patients had hand infections. Staphylococcus aureus was isolated from thirty-nine (39) patients. Gram Negative bacilli, including Salmonella were more isolated from patients with diabetes mellitus or Hgb SS or SC. The Gram stain results correlated with the culture result 90%. When Gram Positive cocci were demonstrated in the primary microscopic examination, cultures were not mandatory. When no organism was demonstrated on primary Gram stain or the patient was diabetic or a sickler, cultures of the specimens were done. The Gram stain, well performed, remains a useful, inexpensive, technologically appropriate laboratory test for abetting decision making in patients with upper extremity suppurative infections. Organisms encountered in this study included: Staphylococcus aureus, Streptococcus pyogenes, Salmonella typhi, Proteus mirabilis, Pseudomonas aeruginosa, and Coliforms.

Treatment of the dying in the acute care hospital. Advanced dementia and metastatic cancer.

BACKGROUND: Most Americans die in the acute care hospital, where aggressive, life-prolonging interventions are readily performed. Although patients with incurable illness might prefer palliative care, perceived differences in prognosis by physicians may influence the type of care provided. Patients with advanced cancer and advanced dementia represent 2 extremes in the use of hospice services and may also be treated differently in the acute care hospital. We tested this hypothesis and quantitated the use of nonpalliative interventions in hospitalized, incurably ill patients. METHODS: Charts of elderly patients with advanced dementia or metastatic solid tumor malignancy who died during a 13-month period in a tertiary care acute teaching hospital were reviewed. Main outcome measures included the number of patients receiving invasive of noninvasive (but complex) diagnostic tests, invasive nonpalliative treatments, cardiopulmonary resuscitation, systemic antibiotics, and do-not-resuscitate orders. RESULTS: Charts of 164 patients (80 with dementia and 84 with cancer) were reviewed. Overall, 47% received invasive nonpalliative treatments. Controlling for age, sex, length of stay, and insurance status, the groups were equally likely to receive nonpalliative treatments (P = .75), but patients with dementia were more likely to receive new feeding tubes (P = .02). Cardiopulmonary resuscitation was attempted for 24% of each group. Patients with cancer more often received invasive (41% vs 13%; P = .002) and complex noninvasive diagnostic tests (49% vs 23%; P = .02). Overall, 88% received antibiotics, often empirically, but, controlling for neutropenia and invasive tests and treatments, patients with dementia were significantly more likely to receive antibiotics for an identifiable infection (P = .004). CONCLUSIONS: Incurably ill patients often receive nonpalliative interventions at the end of life. Patients with cancer receive more diagnostic tests, but patients with dementia receive more enteral tube feeding. Patients commonly receive systemic antibiotics, often empirically. Cardiopulmonary resuscitation is equally applied, but is out of proportion to expected survival.

Barriers to completion of health care proxies: an examination of ethnic differences.

BACKGROUND: Advance directives have not been uniformly used by different segments of the US population and studies have consistently shown a lower prevalence of advance directives among African Americans and Hispanics compared with non-Hispanic whites. OBJECTIVE: To examine barriers to completion of health care proxies for different ethnic groups. METHODS: One hundred ninety-seven subjects aged 65 years or older self-identified as African American (n = 65), Hispanic (n = 65), or non-Hispanic white (n = 67) attending a geriatrics and internal medicine outpatient clinic of a large New York City teaching hospital were administered a questionnaire. Questionnaires were developed to examine potential barriers to completion of health care proxies. Barriers were drawn from the literature and from focus groups. RESULTS: Significant predictors of proxy completion using logistic regression analysis included knowledge of health care proxies, availability of a health care agent, exposure to mechanical ventilation, age, and self-reported health status as fair to poor. Subjects who believed that a health care agent was irrelevant in the setting of involved family were significantly less likely to have completed a health care proxy. Although there were significant differences in the baseline completion rates of health care proxies for the 3 ethnic groups, ethnicity did not predict prior appointment of a health care agent in multivariate analysis. CONCLUSIONS: Differences in health care proxy completion rates across white, African American, and Hispanic elderly individuals in this New York City population seem to be related to potentially reversible barriers such as lack of knowledge and the perceived irrelevance of advance directives in the setting of involved family. Enhanced educational efforts of both health care personnel and patients could increase the rate of formal health care proxy appointment.

High short-term mortality in hospitalized patients with advanced dementia: lack of benefit of tube feeding.

BACKGROUND: The influence of tube feeding on survival in hospitalized patients with advanced dementia is controversial. OBJECTIVE: To assess long-term survival in an inception cohort, incident tube feeding placement during the index hospitalization, and the influence of tube feeding on survival in this group of patients. SUBJECTS AND METHODS: Ninety-nine hospitalized patients with advanced dementia and an available surrogate decision maker were followed up through and after the index hospitalization for mortality and placement of a feeding tube. Other variables measured included advance directive status, presence of a long-term primary care physician, level of involvement of the surrogate decision maker, admitting diagnosis, prior hospitalizations, comorbidities, and diagnosis related group diagnostic category. RESULTS: A new feeding tube was placed in 50% (51/99) of the study patients during the index hospitalization, 31% (31/99) left the hospital without a feeding tube, and 17% (17/99) were admitted with a feeding tube already in place. By stepwise logistic regression analysis, predictors of new feeding tube placement included African American ethnicity (odds ratio, 9.43; 95% confidence interval, 2.1-43.2) and residence in a nursing home (odds ratio, 4.9; 95% confidence interval, 1.02-2.5). Median survival of the 99 patients was 175 days. Eighty-five (85%) survived the index hospitalization, and 28 (28%) were still alive at last follow-up, a range of 1.3 to 4.2 years after enrollment in the study. Tube feeding was not associated with survival (P =.90). An admitting diagnosis of infection was associated with higher mortality (odds ratio, 1.9; 95% confidence interval, 1.01-3.6). CONCLUSIONS: In this cohort of hospitalized patients with advanced dementia, risk of receiving a new feeding tube is high, associated with African American ethnicity, and prior residence in a nursing home, and has no measurable influence on survival. With or without a feeding tube, these patients have a 50% six-month median mortality.

Marked improvement in recognition and completion of health care proxies. A randomized controlled trial of counseling by hospital patient representatives.

BACKGROUND: Advance directives provide a means for patients to retain influence on their medical care should decisional capacity be lost. Several studies have now demonstrated that advance directives that are completed in the ambulatory care setting are rarely available and recognized when patients are admitted to the acute care hospital. OBJECTIVE: To evaluate a generalizable model for improving recognition of previously completed advance directives and for promoting appointment of health care proxies in hospitalized patients. METHODS: Hospitalized elderly patients were randomly assigned to receive the intervention or usual care (n = 190). Intervention patients with capacity were counseled by hospital patient representatives about advance directives and encouraged to complete health care proxies. Patients with existing proxies had this information noted in their charts. For patients without capacity, counselors reviewed their charts for proxy documentation and if absent, contacted patients' next of kin and private physicians to determine proxy status. Usual care patients were not contacted by patient representatives. RESULTS: Forty-eight percent of intervention patients completed a new proxy or had a previously completed proxy identified compared with 6% of controls (P < .001). For patients with capacity, 22% of intervention patients had a previously appointed proxy agent identified compared with 6% of controls (P < .001). Thirty-six percent of intervention patients appointed a proxy decision maker compared with 0% of controls (P < .02). For patients without capacity, 31% of intervention patients had previously appointed proxies identified compared with 6% of controls (P < .001). CONCLUSIONS: Counseling by hospital patient representatives is an effective and generalizable means of improving recognition and execution of advance directives in the acute care hospital.

Racial differences in pre- and postmenopausal bone homeostasis: association with bone density.

The disparity in fracture incidence and bone mass in women of European (white) and African (black) ancestry is of unknown etiology. To determine if racial differences in bone mass reflected racial differences in the mechanisms of bone turnover underlying bone mineral loss, we measured serum osteocalcin, serum alkaline phosphatase, fasting urinary calcium and hydroxyproline excretion, 24 h urinary excretion of calcium and sodium, and dietary intakes of calcium and vitamin D in 263 healthy pre-, peri-, and postmenopausal white and black women. In addition, radial and spinal bone density were measured cross-sectionally for comparison with biochemical measures of bone turnover. The biochemical parameters thought to reflect bone resorption (fasting urinary calcium and hydroxyproline excretions) were lower in black than in white women throughout the age and menopausal stages studied. The parameters thought to reflect bone formation (alkaline phosphatase and osteocalcin), were similar in the two racial groups among the premenopausal women, but osteocalcin was significantly lower among the peri- and postmenopausal blacks. Cross sectionally measured radial bone density increased with age in premenopausal black women, but it did not change with age in the white premenopausal subjects, a statistically significant difference. In peri- and postmenopausal women radial density declined significantly with years after menopause in both racial groups, but the rate of decline was significantly slower in the black women. Lumbar bone density in premenopausal white and black women did not change with age. After menopause lumbar bone density declined significantly and similarly in both racial groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Alterations in calcium, vitamin D, and parathyroid hormone physiology in normal men with aging: relationship to the development of senile osteopenia.

The effects of aging on calcium and bone metabolism have not been systematically examined in men. To identify age-related alterations in vitamin D and PTH physiology and to assess their impact on skeletal health, we studied 62 normal men, aged 30-92 yr. The men were in excellent health, and none had any evidence of metabolic bone disease and/or known risk factors for osteopenia. Serum 25-hydroxyvitamin D (25OHD) concentrations declined steadily with advancing age (r = -0.47; P less than 0.001), and there was a corresponding decline in serum 24,25-dihydroxyvitamin D [24,25-(OH)2D] levels (r = -0.41; P less than 0.001). Serum 1,25-(OH)2D concentrations, however, did not vary over this age range (r = -0.07; P = NS). Plasma PTH levels increased with aging (r = -0.24; P less than 0.001), and there was a concomitant increase in urinary cAMP excretion (r = 0.38; P less than 0.001). Renal function (creatinine clearance) clearly declined with increasing age (r = -0.71; P less than 0.001). In conjunction with these changes in calcium metabolism, radial and vertebral bone mineral content declined. Whereas the fall in radial bone mineral content (single photon absorptiometry) at both proximal and distal sites was slight, there was a marked decrease in vertebral bone mineral content, as measured by quantitative computed tomography (r = -0.72; P less than 0.0001). The fall in vertebral bone mineral content correlated well with the declines in serum 25OHD and 24,25-(OH)2D concentrations (r = 0.47; P less than 0.001 and r = 0.51; P less than 0.001, respectively) and with the decline in renal function (r = 0.46; P less than 0.001). Multiple regression analysis revealed that the effects of aging on bone mineral content could be accounted for in large part by concomitant changes in mineral metabolism. Both the decline in renal function and the fall in serum 24,25-(OH)2D levels were closely associated with the fall in bone mineral content. These results indicate that a decline in renal function and alterations in vitamin D metabolism occur with aging in normal men. These changes contribute to, if not cause, the associated decline in skeletal mineral content in aging men.

A prospective study of bone loss in African-American and white women--a clinical research center study.

Although bone loss occurs universally with age, the incidence of age-related osteoporotic fractures varies widely among ethnic groups. In the U.S., age-adjusted hip fracture incidence is 50% lower in African-American than in white women. Adult African-American women also have higher bone mass, but it is not known whether this difference is entirely due to higher peak bone mass or also results from slower rates of bone loss. Rates of bone loss were measured prospectively in 122 white and 121 African-American healthy, nonobese, pre- and postmenopausal women. Bone density was measured at 6-month intervals over a mean of 3-4 yr using single and dual photon absorptiometry of the forearm (cortical bone) and spine (trabecular bone). Similar rates of premenopausal bone loss were documented in both white and African-American women. However, in early menopause, bone loss was faster in the white women in the forearm (-2.4%/yr in whites vs. -1.2%/yr in African-Americans; P = 0.045), with a similar trend in the spine (-2.2%/yr in whites vs. -1.3/yr in African-Americans; P = 0.27). In women more than 5 yr postmenopause, the rates of bone loss did not differ by ethnic group. Our results indicate that the higher bone mass in African-American women is largely due to the attainment of a greater peak bone mass by early adulthood. However, slower rates of bone loss in the early postmenopausal period may also contribute to the higher bone density of older African-American women. Although bone loss occurs in both groups, there are ethnic differences in bone loss rates which indicate that data derived from white women cannot be simply extrapolated to nonwhite populations. Ethnic group-specific data on the determinants of bone homeostasis are needed.

Calcium, vitamin D, and parathyroid hormone status in young white and black women: association with racial differences in bone mass.

The etiology of the racial disparity in bone mass and fracture rate is unknown. Since the PTH-vitamin D endocrine system is a major regulator of calcium metabolism and bone turnover, this cross-sectional study examined the relationship of radial and lumbar bone density to vitamin D metabolite and PTH concentrations and to calcium intake and excretion in 67 white and 70 black highly comparable, healthy, premenopausal women. Bone density at both radial and lumbar sites was higher in blacks than in whites. Serum 25-hydroxyvitamin D was slightly but not statistically significantly (P = 0.08), lower in blacks than in whites, but there were no racial differences in 1,25-dihydroxyvitamin D, PTH, or renal tubular maximum for reabsorption of phosphate. The mean 25-hydroxyvitamin D concentration in blacks was well within the normal range and was not associated with evidence of secondary hyperparathyroidism. There were no correlations of bone density to vitamin D or PTH concentrations. Although there were no racial differences in dietary intake of calcium and vitamin D or in sodium excretion, 24-h urinary calcium excretion was significantly lower in blacks than in whites, and calcium excretion was inversely associated with radial bone density. In contrast to previous reports, in healthy, normal weight, premenopausal black women there is no evidence of vitamin D deficiency or secondary hyperparathyroidism, suggesting that factors other than the vitamin D-PTH axis are responsible for racial differences in bone mass.

Radial and vertebral bone density in white and black women: evidence for racial differences in premenopausal bone homeostasis.

The reasons for a different incidence of osteoporotic fractures in white and black women are unknown. Previous racial comparisons of bone mass have been limited by racial differences in body weight and socioeconomic, health, and nutritional status. This cross-sectional study examined bone density in 105 black and 114 white healthy nonobese women, 24-65 yr old, using dual photon absorptiometry of the lumbar spine and single photon absorptiometry of the distal radius. Bone density at both sites was higher in blacks at all ages than in whites. When adjusted for age and body mass index, mean bone density was 6.5% higher in blacks at both spine and radius (P less than 0.0001). The cross-sectional rate of decline of vertebral bone density was similar between races; however, radial density increased 3.8%/decade (P = 0.03) in premenopausal blacks under age 46 yr, while it declined 3.2%/decade (P = 0.09) in premenopausal whites. The racial difference in slopes in these premenopausal women is significant (P = 0.002). These findings suggest that attainment of higher peak bone mass and delayed onset of bone loss contribute to the lower incidence of osteoporotic fractures in black women.

Serum protein concentrations and bone mineral content in aging normal men.

Low serum protein levels and low dietary protein intakes possibly influence bone metabolism. To evaluate the relationships among serum protein concentrations, protein intakes, and bone mineral content (BMC), we have examined two populations of normal men. BMC was measured at two radial sites and a vertebral site. Aging was associated with a fall in BMC at all sites. Serum albumin levels also fell with age and were related to BMC. Albumin concentrations were associated with BMC when other variables (calcium and protein intake, vitamin D levels, parathyroid hormone, and urinary calcium) also were considered. Thus, alterations in protein metabolism may affect BMC and may play a role in the genesis of senile osteopenia.

Effect of source strength and attenuation on dual photon absorptiometry.

A systematic error in dual photon absorptiometry (DPA) measurements of bone mineral density (BMD) related to source strength has been previously described and attributed to an erroneous algorithm for deadtime correction. Since detected counts (or photon flux) is a product of source strength and attenuation, the effect of various source activities and attenuation depths on BMD calculations were evaluated using a phantom. Ten DPA scans were acquired at two source strengths, 0.3 and 1.0 Ci, and at each of two water depths, 16.4 and 24.5 cm. These activities and depths are within the range encountered clinically. Scans were acquired and processed using a commercially available lumbar spine scanner and software, and were reanalyzed with two upgraded versions of software. Mean BMD obtained with the initial software varied by 2 to 14% with changes in both sources strength and attenuating depth. Software revisions reduced but did not entirely eliminate these differences. The remaining 6% discrepancy is of sufficient magnitude to influence both patient management and research investigations.

Selected bibliography of recent articles in ethics and geriatrics.

The disciplines of bioethics and geriatrics have had parallel development in recent years. From small and relatively esoteric fields 15 or 20 years ago, both have grown enormously. Although the numbers of geriatricians and ethicists in practice or in academic centers have increased substantially, these disciplines represent areas in which better understanding is sorely needed. This bibliography is intended to assist the clinician in locating salient literature concerning bioethical issues in geriatric medicine and research. It is highly selective; it does not attempt to cover all the literature on bioethics. There are several excellent general bioethics bibliographies for clinicians in the recent literature, as well (not limited to clinical journals or clinical topics), some of which are included in section 13 for the reader's further information. The ethical issues that arise in geriatric medicine are similar to those that arise in the care of younger patients, but certain kinds of problems happen with far greater frequency. Dilemmas concerning decisions about care at the end of life are particularly relevant in geriatrics, as persons of extreme old age are often presented with choices about life-sustaining therapy when critical illness occurs. This includes decisions about cardiopulmonary resuscitation and nutritional support. When these clinical decisions arise in the care of patients who cannot decide for themselves, the question arises as to what role the assessment of "quality of life" ought to play in decisions to pursue or to forego life-sustaining therapy. Informed consent to treatment and to participation in research has been an important area of ethical investigation. Dilemmas about consent to treatment are complicated in some elderly populations because of the higher incidence of cognitive impairment and the higher incidence of the clinician's suspicion (or assumption) of cognitive impairment. In consent to research, there are additional issues of voluntariness and equitable selection, especially when subjects are residents of nursing homes. Because of the increasing numbers of elderly persons in our society, and because of the role of social resources (federal, state, and local) in acute and long-term medical major concern in gerontologic bioethics. The topic headings for this bibliography reflect these common issues which arise in the care of the elderly.+2

Marked decline in trabecular bone mineral content in healthy men with age: lack of association with sex steroid levels.

To define the association of age-related changes in bone mineral content to gonadal function in normal men, we measured radial (largely cortical) and vertebral (largely trabecular) bone mineral content (BMC), testosterone (total and free), estrone and estradiol-17B levels in 62 healthy subjects, ages 30 to 92. Radial BMC fell 2 to 3.4% per decade but vertebral trabecular BMC declined more rapidly at 12% per decade. Of the sex steroids measured the only statistically significant change occurred in free testosterone levels which decreased with age (r = -.57, P less than .0001). Free testosterone levels correlated significantly with trabecular vertebral BMC (r = .458, P less than .0002) but not with bone mineral measures at the predominantly cortical radial sites. However, by multiple regression analysis free testosterone did not add to the effect of age on vertebral BMC. There were no associations of total testosterone, estrone, or estradiol levels to bone mineral content at any of the three sites measured in these healthy men. Age-related declines in male gonadal function do not appear to be of primary importance in male age-related bone loss.

Barriers to obtaining consent in dementia research: implications for surrogate decision-making.

OBJECTIVE: To identify barriers to informed consent in research involving subjects with advanced dementia. DESIGN: A randomized controlled clinical trial of palliative care approaches, compared with usual care, in subjects with advanced dementia who are hospitalized. SETTING: A large metropolitan teaching hospital. PARTICIPANTS: All patients older than 65 years of age who have advanced dementia and a Functional Assessment Staging score of 6d to 7f and have been admitted to the hospital. MEASUREMENTS: Surrogates for all eligible subjects were approached for consent to enroll their family members in the trial. Reasons for refusal to enroll in the study were recorded and categorized as either informed refusal (i.e., the surrogate understood the research protocol but declined to give consent for participation) or as a barrier to informed consent (i.e., the surrogates could not participate in the informed consent process or there was no functional surrogate). RESULTS: Forty-nine percent of 146 eligible subjects could not be enrolled in the study. Only four surrogates refused consent for their family members. Of the remaining 68 patients, 41 eligible subjects' surrogates could not be engaged in the informed consent process, and 22 subjects did not have a functional surrogate to consent for research. CONCLUSIONS: Absence of functional surrogate decision-makers is a major barrier to research and clinical decision-making for hospitalized patients with advanced dementia.

Enhancement of proxy appointment for older persons: physician counselling in the ambulatory setting.

OBJECTIVE: To determine the effectiveness of physician-initiated counselling on the rate of health care proxy appointment. DESIGN: Observational study of an intervention in a convenience sample. SETTING: A geriatric outpatient clinic in a tertiary care teaching hospital, New York, New York. PARTICIPANTS: A total of 687 patients enrolled in the geriatric clinic during the study period March 1991 through June 1993. INTERVENTION: Physician counselling about the New York State Health Care Proxy Law, distribution of educational materials and healthcare proxy forms, and reminders in 331 of 466 eligible patients. MEASUREMENTS: Rate of healthcare proxy appointment in eligible and counselled groups; predictors of appointment and non-appointment; time elapsed from counselling to appointment; reasons for non-appointment; characteristics of the proxy appointment process. RESULTS: A healthcare proxy was appointed for 31.5% of patients eligible for counselling and for 44% of patients who actually received the intervention, compared with a 2.3% proxy appointment rate at baseline. Eighty-one percent of the patients completing the proxy appointment process did so at or before their third clinic return visit after the counselling intervention. Of the counselled patients who did not appoint a proxy, 25% explicitly declined, and 75% had not come to a decision by the end of the study period. Proxy completion was associated with ethnicity, education, and more frequent clinic visits. Of those who appointed a proxy, 97% had good or fair comprehension of the procedure, 92% discussed the appointment with their designees, 63% appointed a daughter or son, and 80% discussed their wishes for care at the end of life with their proxy. CONCLUSIONS: Physician counselling of older outpatients is an effective means of increasing healthcare proxy appointments.

Vertebral artery trauma: acute recognition and treatment.

Vertebral artery injury is uncommon and may be initially unrecognized. Sequelae of vertebral artery injury include arteriovenous fistulae and pseudoaneurysms that may appear months after injury. The incidence of the sequelae is unknown. Cervical angiography used in the routine evaluation of a patient with penetrating neck trauma readily demonstrates vertebral artery injuries. This series of 13 cases demonstrates the low morbidity associated with the treatment of isolated vertebral artery injuries. A technique for proximal and distal ligation of the vertebral artery is presented. Its use is recommended in the treatment of any patient with vertebral artery injury who has a normal contralateral vertebral artery and no demonstrable extracranial branches from the vertebral artery to the spinal cord.

Combined carotid-vertebral arterial trauma.

Eight patients with simultaneous penetrating trauma to the carotid and vertebral arteries among 129 carotid and 53 vertebral arterial injuries have been treated in the last 14 years. In contrast to a 10% mortality with isolated carotid or vertebral trauma, the mortality associated with this injury complex was 50%. This high mortality directly related to the overall complexity of the trauma sustained by these patients. The liberal use of arteriography to assess penetrating cervical trauma has enhanced the diagnosis of these injuries. We recommend simultaneous surgical management of the carotid and vertebral arterial injury through an extended anterior cervical approach.

The outcome of suprapubic prostatectomy: a contemporary series in the developing world.

OBJECTIVES: To assess the appropriateness of the technique of suprapubic prostatectomy using a removable bladder neck partition suture for use in a developing world hospital and to provide contemporary open prostatectomy outcome data currently lacking in the world's literature. METHODS: From 1984 to 1994, 240 consecutive patients presenting to a developing world hospital with acute urinary retention underwent suprapubic prostatectomy using a removable bladder neck partition suture. The average length of time from bladder decompression until operation was 2.5 months. The outcome of these cases was retrospectively analyzed. RESULTS: The overall early complication rate was 19.6%. There were no deaths. The transfusion rate was 4.6%. Clot retention occurred in 6.7%, and 2.9% required return to the operating room for evaluation. For the second half of the series, the early complication rate decreased to 8.3%, the clot retention rate to 0.8%, and the transfusion rate to 1.7%. Other early and late complications were minimal. The length of delay from decompression until operation did not affect outcome. CONCLUSIONS: The technique of suprapubic prostatectomy using a removable bladder neck partition suture is appropriate for use in developing world hospitals because of its low morbidity and mortality rates. The outcome in this contemporary series of open prostatectomy cases compares favorably with the outcome from reported contemporary transurethral resection of the prostate (TURP) series. These data demonstrate that suprapubic prostatectomy is an acceptable option when the patient's anatomy or the state of local medical facilities precludes TURP.

The anterior operative approach to the cervical vertebral artery.

BACKGROUND: Vertebral arterial trauma continues to be a perplexing diagnostic and therapeutic challenge. Operative management is often required despite improved radiologic interventions for these injuries. Accounts of the operative approaches to anterior cervical vertebral artery injuries have been limited. STUDY DESIGN: We reviewed our experience with anterior cervical vertebral arterial trauma in 53 consecutive patients requiring operative management during a 14-year period. In seven patients, the vertebral arterial injury was identified at urgent surgical intervention either for an expanded cervical hematoma or active bleeding. The remaining injuries were identified by arteriographic investigation of penetrating cervical trauma. The injuries were equally distributed between the three anatomic zones of the anterior cervical vertebral artery. The general features of the operative approaches that were used to manage these injuries were the emphasis of the study. RESULTS: The anterior approaches to patients with vertical arterial trauma were effective in controlling injuries in all cases. Proximal and distal ligation of the artery adjacent to the injury site was accomplished in 95 percent of the patients. Associated major cervical injuries in 43 percent of the patients (carotid artery, eight patients; pharyngoesophageal, six patients; and neurologic, nine patients) contributed to the postoperative morbidity rate and the overall mortality rate of 10 percent. CONCLUSIONS: The surgeon approaching vertebral arterial trauma should have a clear appreciation of the deep anterior cervical anatomy to expedite the operative management and avoid unnecessary complications related to a misdirected surgical dissection. The descriptions of the operative techniques used in this clinical experience can aid the surgeon in managing patients with vertebral vascular trauma.
