Nucleoplasty With or Without Intradiscal Electrothermal Therapy (IDET) as a Treatment for Lumbar Herniated Disc

BACKGROUND AND OBJECTIVE

In industrialized societies, the prevalence of radicular low back pain has exploded in recent years. The growing economic and personal costs of this challenging entity have led to the development of a wide array of new treatments, ranging from pharmacotherapy with neuropathic medications to open surgical treatment. Among the therapeutic options to emerge are a plethora of minimally invasive treatments aimed at removing nuclear material and lowering intradiscal pressure through devices inserted percutaneously into intervertebral discs. Yet there is a compelling lack of clinical evidence to support the use of these procedures. This study was undertaken to determine the treatment outcomes of 16 consecutive patients with lumbar radicular pain secondary to a herniated disc who underwent nucleoplasty as their primary therapy.

METHODS

Included in this series were nine patients with significant axial back pain, sitting intolerance, and positive discography who also underwent intradiscal electrothermal therapy (IDET). Among the 7 patients who only had nucleoplasty, 4 had 2 discs treated and 3 had 1 disc. In the 9 patients who also had IDET, 6 had 1 disc treated and 3 had 2 discs treated. Of the 32 total disc treatments, 20 were at L5-S1, 10 were at L4-5 and 2, one each for IDET and nucleoplasty, were at L3-4.

RESULTS

In the overall cohort, the average Visual Analogue Scale (VAS) pain score decreased from 6.7 to 5.6 at a mean follow-up of 9 months. In the seven patients who underwent only nucleoplasty, the mean VAS score decreased from 6.0 to 4.8. Only one patient reported a >/=50% reduction in pain score.

CONCLUSIONS

We conclude that with use of the present selection criteria, nucleoplasty is not an effective long-term treatment for lumbar radiculopathy, either alone or with IDET. Before conducting future clinical trials, we recommend modifying these criteria to include only those patients with small (<6-mm) contained disc herniations whose annular integrity is documented by computed tomography discography and corresponding radicular symptoms confirmed by either selective nerve root blocks or electromyography and nerve conduction studies.

Kidney transplantation at the Chinese People's Liberation Army General Hospital

Between October 1977 and December 2004, 2,037 kidney transplants were performed in 1,804 patients with ESRD at the Peoples Liberation Army General Hospital Postgraduate Medical School. Overall graft survival rates at one, 5, 10, 15, and 20 years were 91.6%, 79.3%, 64.3%, 53.8%, and 47.6%, respectively. The number of transplants significantly increased during the past decade. One-year patient and graft survival rates have increased from 40% and 35% in the 1970s to 98% and 96% in the 2000s, respectively. Since CSA was introduced to our clinic, one-year graft survival rates have increased from 33% to 93% and the half-lives have significantly improved from 13.1 years to 21.7 years. Also, the graft survival rate for patients on CSA-based triple therapy using MMF was about 18% higher at 5 years than those for patients using AZA (92% vs. 74%, p < 0.001), and 11% higher at 10 years (71% vs. 60%, p < 0.01). Our analysis showed that transplant year, DGF, rejection, immunosuppressive regimen, ABO blood group, and original disease were independent factors impacting on graft survival and poor HLA matching with 5-6 mismatches had an adverse effect on graft survival compared with 1-2 mismatches. Infection, cardio- and cerebral accidents and hepatic failure were the 3 main causes of death in transplant recipients.

Morbidity and Mortality Characteristics of Infants Hospitalized in the Pediatrics Department of the Largest Turkish Military Hospital in 2001

A descriptive study was conducted in the pediatric inpatient unit of Gulhane Military Medical Academy, to investigate the morbidity and mortality characteristics of 532 infants hospitalized between January 1 and December 31, 2001, for treatment purposes. Of the study participants, 55.8% were boys and 44.2% were girls. The most common cause of hospitalization was neonatal hyperbilirubinemia (19.7%). The most common admission month was January (12.4%). Of 532 infants, 510 (95.9%) were discharged, whereas 22 patients died in the hospital. Twenty-one patients died in the neonatal period, and respiratory distress syndrome and neonatal sepsis were identified as the most common causes of death. Our finding of associations between male gender and low birth weight and hospital death is consistent with previous knowledge. Despite the high frequencies of pneumonia and gastroenteritis as admission diagnoses, the finding of only one pneumonia-related death and no gastroenteritis-related deaths in the study population is pleasing.

Who sees the young women? A resource-sharing model for providing comprehensive adolescent women's health care

Female adolescents are underserved in military medicine. This article describes an innovation in preventive care created to address the unmet health needs of female adolescents at a large military community hospital. A "Teen Women's Health Clinic" was created through shared resources between the Departments of Pediatrics and Gynecology. Female teenagers visited the clinic for routine gynecologic care, preventive health maintenance, acute care treatment for gynecologic and general complaints, and subspecialty referral consultation for adolescent medicine. The mean appointment fill rate from May 2001 through April 2002 was 93.8% (range, 63-127%). The mean no-show rate was 16% (range, 0-27%). There was minimal cost to the program. Comprehensive teen women's health with acute and preventive adolescent health care is achievable at the community hospital level at little expense through cooperation between departments. The clinic was well attended, on average working near full capacity, with a low no-show rate for teenagers. Reproduction of this model may be achieved throughout the Department of Defense at minimal cost.

EX SAIF SEREEA II - The Field Hospital Clinical Report

This paper places on record the clinical activity of the hospital facilities run by 22 Field Hospital on Exercise SAIF SEREEA II in Oman from August to November 2001. There were 1322 episodes of illness resulting in a hospital admission. The mean rate of admission was 1.96 patients per thousand per day (SD 13.62). The main causes of admission were gastrointestinal illness, conditions related to the heat and injuries. The reporting of health service utilisation data is an important duty of medical personnel during overseas deployments in order to add to the dataset available for the estimation of medical workload for future operations.

Effect of managed care enrollment on primary and repeat cesarean rates among U.S. Department of Defense health care beneficiaries in military and civilian hospitals worldwide, 1999-2002

BACKGROUND

In response to rising cesarean rates, it is reasonable for health care organizations to look to a managed care model as a means of controlling further rate increases. However, little conclusive evidence exists to support this solution. We undertook a study of the Department of Defense health care beneficiary population to assess the impact of enrollment in TRICARE Prime, the Department's managed care health plan, on cesarean delivery rates.

METHODS

Pooled hospital discharge records from 1999-2002 for live, singleton births were analyzed to calculate primary and repeat cesarean rates for TRICARE Prime and non-Prime beneficiaries in the military and civilian hospitals that comprise the Department of Defense health care network. Stepwise logistic regression was used to calculate adjusted odds ratios for clinical indicators for each combination of health plan and hospital setting using the chi2 difference(p <0.05)to eliminate nonsignificant variables from the model. Total primary and repeat cesarean rates were compared with primary and repeat cesarean rates for women with no reported clinical complications to account for differences in case mix across subgroups. Statistical significance of the differences calculated for subgroups was assessed using chi2.

RESULTS

Primary cesarean rates were significantly lower for TRICARE Prime enrollees relative to non-Prime beneficiaries for all race subgroups and three of five age subgroups in military hospitals and four of five age subgroups in civilian hospitals. No significant differences in repeat cesarean rates were observed between Prime and non-Prime beneficiaries within any race or age subgroup. Breech presentation followed by dystocia, fetal distress, and other complications were significant predictors for primary cesarean. Previous cesarean delivery was the leading predictor for repeat cesarean delivery. Primary and repeat cesarean rates observed for military hospitals were consistently lower than rates observed for civilian hospitals within each health plan type and age group.

CONCLUSIONS

Enrollment in the managed care health plan was significantly associated with lower risk of primary cesarean delivery relative to membership in other health plans offered to Department of Defense health care beneficiaries. Repeat cesarean rates in this population varied independently of health plan type. Primary cesarean delivery was generally associated with clinical complications, whereas previous cesarean delivery was the strongest indicator for a repeat cesarean delivery. A clear explanation of reduced cesarean rates for Prime enrollees remains elusive, but it is likely that factors beyond individual practitioner decision-making were at work.

Characteristics of repeat users of an inpatient psychiatry service at a large military tertiary care hospital

OBJECTIVE

The purpose of this study was to identify clinical and demographic variables that correlated with readmission to a large tertiary care military psychiatric inpatient service located in the Washington, DC area.

METHODS

Data from 983 consecutive inpatient admissions (comprised of 814 individual patients) over a 13-month period (July 1999-July 2000) were abstracted from medical records for retrospective analysis. Repeat users were defined as those individuals receiving two or more inpatient admissions to Walter Reed Army Medical Center during the study period. Statistical comparisons were made between repeat and single admission groups to identify variables predictive of rehospitalization.

RESULTS

Of 814 individual patients under study, 117 (14%) were identified as repeat users. A history of childhood psychiatric problems, previous psychiatric hospitalization, current or past substance abuse, legal problems, and presence of a psychotic or nonbipolar mood disorder were associated with readmission after controlling for active duty status. Current comorbid substance use or personality disorder diagnoses were not predictive. Having at least one child was protective against readmission. The 117 repeat users accounted for 3,838 (37%) of the total 10,393 hospital bed-days during the study period. Logistic regression analysis of all variables correlated with readmission demonstrated statistical significance for past psychiatric hospitalization and age of onset of psychiatric problems before age 18 when active duty status, age, and gender variables were included in the equation.

CONCLUSIONS

This study is one of the largest to investigate predictors of rehospitalization in a population that enjoys universal "free" access to comprehensive mental health care services and other benefits of employment. This retrospective analysis documented three important facts: That there seem to be only minor differences between military and civilians with respect to variables associated with psychiatric rehospitalization, that a relatively small proportion of patients accounted for a disproportionately large number of inpatient bed-days, and that an unexpectedly high proportion of active duty patients admitted to this study site reported childhood psychiatric problems and psychiatric hospitalizations before their first hospitalization at Walter Reed Army Medical Center.

Gestational age-specific growth parameters for infants born at US military hospitals

BACKGROUND

Military hospitals currently use gestational age-specific growth curves based on data collected in Denver, Colo, from 1948 to 1961. A number of population and environmental factors and medical practice changes may make these curves nonrepresentative.

OBJECTIVE

Determine if presently used growth curves represent norms for infants born in military hospitals and create new curves for use in military hospitals.

METHODS

Data were collected from medical records of tertiary- and primary-care military hospitals. We created growth curves created for birth weight, length, and head circumference and compared these curves at gestational ages 23-42 weeks to previously published norms and to 1998 national vital statistics. Racial and ethnic differences between groups were compared. A retrospective analysis of blood-glucose measurements for healthy term infants was performed to identify potential safety issues.

RESULTS

Significant increases in growth parameters were noted for infants born in military hospitals. Specific racial and ethnic groups within the military also had an increase when compared with these groups in the United States as a whole. Less than 1% of infants classified as large for gestational age (LGA) according by old standards but average for gestational age (AGA) according to new curves experienced hypoglycemia.

CONCLUSION

Published growth curves may not represent infants born in military hospitals. Term infants born in military hospitals as a group and in racial and ethnic subgroups are larger than term infants born in US civilian hospitals. Prospective use of curves will help to validate their long-term applicability in military and civilian nurseries.

Surgical workload from an integrated UK field hospital during the 2003 Gulf conflict

AIMS

This paper reports the surgical experience of a UK reserve field surgical hospital during military operations in Iraq during March and April 2003. Particular reference is given to the integration of the surgical specialities, consultant led and multidisciplinary teamworking in the treatment of military and civilian casualties from all sources and of all causes. METHODS All surgical workload data was collected prospectively for the warfighting (Phase One) and specialist referral (Phase Two) phases of the operation. Standard military and Red Cross protocols were used for all injuries and microbiology studies were undertaken for penetrating ballistic injuries. Operations were classified by anatomical region; upper or lower limb; head and neck; thoracic; abdominal, including genitourinary; ophthalmic; and burns, and by whether they were primary; secondary planned or secondary unplanned.

RESULTS

A wide range of patterns of wounding arising from combat and non-combat related military and civilian trauma and burns were seen and treated. 323 operations were performed. There were 116 operations in phase one and 207 operations in phase two. There were 160 primary procedures (new patients), 146 secondary planned and 17 unplanned procedures (range one to eight procedures per patient). Close integration of general, orthopaedic, plastic, maxillofacial, ophthalmic and neurological surgeons and general and ITU anaesthetists allowed the delivery of a range of specialist treatment to a heterogenous patient population, including children as young as 6 months and a lady in the advanced stages of pregnancy.

CONCLUSIONS

Patterns of wounding in casualties surviving to reach specialist field hospital care were similar to those reported in other high intensity conflicts. A consultant led, multidisciplinary approach with field intensive care facilities allowed combined, staged and safe surgery for complex, multi-organ and multi-limb trauma in an austere environment.

Dental emergency rates at two expeditionary medical support facilities supporting operations enduring and Iraqi Freedom

This study reports dental emergency rates and distribution of causes of dental emergencies at two expeditionary medical support facilities supporting operations Enduring Freedom/ Iraqi Freedom. A retrospective cohort analysis of 9948 soldiers deployed to Prince Sultan Air Base, Kingdom of Saudi Arabia, and 1467 soldiers at Baghdad International Airport, Iraq, was accomplished from a phased deployment from January 2003 to September 2003. Procedures were divided into 11 categories: endodontic, extraction of teeth other than third molars, extraction of third molar teeth, restoration of teeth (caries), restoration of broken teeth (not caries), orthodontic bracket/wire problem, sensitive teeth, temperomandibular pain, periodontal, oral pathology, and prosthodontic. The dental emergency rates for Prince Sultan Air Base and Baghdad International Airport were 153 and 145 dental emergencies per 1000 soldiers per year, respectively. Most of the emergencies were because of dental caries. Pain from third molars was the second most common reason for visiting the dental clinic.

Cardiopulmonary and Mental Health Diagnoses Surrounding the September 11 Terrorist Acts in a Military Population

BACKGROUND

In addition to psychological disorders, emotional stress can trigger a chain of neurohumoral imbalances that can manifest as cardiopulmonary complaints. No studies were identified that used objective clinical data on complaints after the terrorist attacks of September 11, 2001. The purpose of this descriptive study was to identify all cardiopulmonary and psychological diagnoses among active duty personnel seeking care at a military treatment facility and/or its ancillary facilities before and after September 11, 2001.

METHODS

The study population included 40,981 active duty military personnel between August 13, 2001 and October 9, 2001 (4 weeks before and 4 weeks after September 11, 2001). Demographic and diagnostic data were obtained from the Composite Health Care System for each visit during the study period. The outcomes of interest were psychological and cardiopulmonary diagnoses.

RESULTS

There were 19,595 clinic visits before September 11, 2001 compared to 19,207 clinic visits in the 4 weeks after September 11. There was no increase in total psychological diagnoses in the postexposure period, compared with the preexposure period (risk ratio (RR), 0.97; 95% confidence interval (CI), 0.84-1.11). The only statistically significant finding was a decrease in diagnoses of psychoses (RR, 0.62; 95% confidence interval, 0.42-0.91). However, diagnoses of depressive disorders were increased in the postexposure period (RR, 1.61; 95% CI, 0.89-2.90; p = 0.11). Total cardiopulmonary diagnoses did not increase in the postexposure period, compared with the preexposure period (RR, 0.96; 95% CI, 0.91-1.02).

CONCLUSIONS

This descriptive study failed to identify evidence that any changes in cardiopulmonary or mental health diagnoses were attributable to September 11 terrorist attacks. In the unfortunate event of another national tragedy, it is recommended that health care professionals administer a questionnaire to determine why patients are seeking care after the tragedy. These data could be linked to International Classification of Diseases data to determine the effects of the tragedy on the health of personnel and their utilization of health care services.

An Analysis of Maxillofacial Fractures: A 5-Year Survey of 157 Patients

The purpose of this study was to review retrospectively the outcomes for 157 patients treated for maxillofacial fractures between 1994 and 1999 at one military hospital in Turkey. Significant data were collected according to age, gender, time of injury, type of facial injuries, cause of injury, treatment methods, and postinjury and postoperative complications. Fractures resulting from gunshot wounds were excluded in this study. Fractures were examined in two groups according to the type of fracture, i.e., isolated or combined. Methods of fixation with closed or open reduction were used to treat the fractures. Fixation was performed with miniplates, compression plates, microplates, reconstruction plates, and wires for open reduction, and stabilization was performed with arch bars for closed reduction. Complications were recorded in two groups, i.e., postinjury and postoperative complications. There were 151 male patients (96.18%) and 6 female patients (3.82%). The patients ranged in age from 15 to 62 years (mean, 22.8 years). In our study, it was determined that the most significant causes of maxillofacial fractures were traffic accidents (69 cases, 43.95%) and fighting (42 cases, 26.75%). Most fractures were in the mandible (161 fractures). It was observed that most of the mandibular fractures were in the body (49 fractures, 30.43%) and condylar (42 fractures, 26.09%) regions. Of the 223 maxillofacial fractures, 63.68% (142 fractures) were treated with closed reduction and 36.32% (81 fractures) were treated with open reduction. Postinjury complications included infections (local infection or osteomyelitis), nerve injuries (alveolaris inferior, facial, lingual, and infraorbital nerves), and a salivary gland fistula, and postoperative complications included infection, facial asymmetry, and malocclusion.

Extremity Injuries Remain A High Surgical Workload In A Conflict Zone: Experiences Of A British Field Hospital In Iraq, 2003

BACKGROUND

During this conflict 34 Field Hospital, the sole Coalition field hospital located in Iraq, received and treated casualties with a wide range of injuries. Located very close to the front line during the period of combat hostilities, it was potentially going to deal with relatively fewer battle-injured extremities.

METHOD

A retrospective review of battle casualties admitted to the hospital was carried out based on casualty records and operating theatre logbooks. Data was collected for the period between the 26th March and the 8th May, focusing on casualties who had surgery for battle-injured extremities during the conflict.

RESULTS

Sixty eight (55%) of the 124 casualties who underwent surgery did so for battle injuries to extremities. 139 (58%) of all operating theatre episodes and 189 (53%) of all surgical procedures undertaken were for battle-injured extremities. Fourteen major limb amputations were carried out from a total of 87 battle-injured limbs that had surgery, giving an amputation rate of sixteen percent (14/87).

CONCLUSION

The experience at 34 Field Hospital confirms that extremity injuries do confer a high surgical workload in war. Surgical resources should, therefore, be aimed at this and surgical teams deployed to such environments should be well versed in the surgical management of casualties with limb trauma.

Impact of deployment of personnel with chronic conditions to forward areas

AIM

To identify reasons for inappropriate deployment of soldiers with chronic conditions to an operational environment.

SETTING

Two British Army field hospitals in Kuwait, 08 February to 17 March 2003, during the period of troop concentration prior to war-fighting (Operation Telic).

POPULATION

All British military personnel on land during the concentration phase, rising to an estimated 28,000 troops.

METHODS

Real-time electronic record maintained of all cases presenting to 22 and 33 Field Hospitals judged to be inappropriately deployed.

RESULTS

50 sequential cases were analysed. 34% were downgraded prior to deployment. Of those who were P2 FE, 85% were judged to have required protection from deployment by down-grading. 20% of all cases had a history of chronic asthma, and of the asthmatics 60% (6/10) were not downgraded. 18% of all cases were deployed while waiting for secondary care investigation or review that should have ensured protection from deployment. No patient had an existing "FT" (forward temperate) or "LT" (lines of communication temperate) grading: but in four cases it was predictable that the patient's underlying condition would be adversely affected by deployment to a desert environment. In 5 cases it was identified that the inappropriate deployment could be attributed to clinical management within the civilian sector, with a consequent failure to institute the necessary downgrading process.

CONCLUSIONS

Review of the medical grading process is needed to protect those soldiers who are awaiting outpatient opinion or definitive diagnosis from investigation, and to provide an employability grading that matches a soldier's fitness for operational role.

A lesson not yet learned

OBJECTIVES

Accounts of numerous military campaigns throughout history have shown that casualties from medical illness usually greatly outnumber combat injuries. We aimed to see whether this remained the case in a modern campaign where predominantly surgical facilities were deployed.

METHODS

We examined 1511 hospital records of inpatients in the Oman theatre during the last three months of Exercise Saif Sareea II and the initial period of Operation Veritas.

RESULTS

Of the 1399 records included, 1033 (74%) required care from a physician, whereas 366 (26%) were treated by surgeons. However, of patients returning to duty in theatre (total 985), 884 (90%) had been treated by physicians and 101 had been treated by surgeons. Notably, only 23 (2%) of these had undergone a surgical procedure.

CONCLUSIONS

Experience in Oman suggests that the lessons of history in respect of casualties in times of conflict are both unlearned and being repeated. The role of the medical specialities in military secondary care should be recognised and deployed facilities should not be defined by surgical capability alone.

Mission creep: an analysis of accident and emergency room activity in a military facility in Bosnia-Herzegovina

OBJECTIVE

To evaluate accident and emergency (A&E) room activity at a Role 3 Multinational Integrated Medical Unit (R3 MIMU) facility in Bosnia-Herzegovina.

METHODS

Retrospective analysis of all patients attending the A&E room from 1st October 1999-30th September 2002.

RESULTS

1864 casualties are included in the analysis. 52.1% of casualties were Bosnian, 43.8% were military. Mean age of casualties was 35.5 years (SD 18.3), range 1-88 years. Traumatic injury was the leading cause of presentation (58.1%). Following treatment 66.7% of all cases were discharged or returned to unit, with 19.8% admitted to a ward area. During the 3 year period there was a 5 fold increase in the number of Bosnian nationals treated, this included 80 children (<13 years).

CONCLUSION

There has been a dramatic increase in Methods A&E use during the period evaluated, Setting of study particularly by the local population. The increasing number of locals treated, both adult and child, has the potential to undermine the R3 MIMU mission and increase dependency within the Bosnian population. A balance is needed to ensure the staff and functions of a hospital are maintained whilst preserving the capability to deal with an influx of military casualties.

Injury patterns in peacekeeping missions: the Kosovo experience

Proper medical deployment planning requires projecting injuries. For this reason, the injury patterns and mechanism of injury were reviewed for an 18-month period in Kosovo, and injury rates and mechanisms were extracted for review. Overall, there were 404 trauma patients treated during the study period. Isolated head and neck injuries accounted for 29.5% (119) of injuries, chest wounds 5.7% (23), abdominal wounds 4.5% (18), and extremities 33.4% (135). Multiply injured patients accounted for the remaining 27.0% (109). When subdivided by mechanism, penetrating injury made up 36.9% (149), whereas blunt trauma accounted for 63.1% (255). Motor vehicle accidents made up the majority of blunt trauma (72.2%). Of penetrating injuries, gunshot wounds accounted for 55%, blast wounds 38%, and stabbings 6.7%. The data clearly demonstrate that humanitarian and peacekeeping missions require preparation for a wide variety of mechanisms of injury beyond the typical penetrating trauma of combat situations.

Dental Emergency Rates at an Expeditionary Medical Support Facility Supporting Operation Enduring Freedom

The purpose of this study was to report the dental emergency rate and the distribution of cause of dental emergencies at an Expeditionary Medical Support +25 medical facility during a 6-month deployment in support of Operation Enduring Freedom. A retrospective cohort analysis of 1,972 soldiers stationed at Seeb Air Base, Sultanate of Oman, was accomplished from a phased deployment from March to September 2002. Procedures were divided into 11 categories: endodontic, extraction of teeth other than third molars, extraction of third molar teeth, restoration of teeth (caries), restoration of broken teeth (not caries), orthodontic bracket/wire problem, sensitive teeth, temperomandibular pain, periodontal, oral pathology, and prosthodontic. One hundred thirty-five dental emergency visits were recorded, corresponding to a rate of 137 dental emergencies per 1,000 soldiers per year. Most of the emergencies (34.8%) were due to caries. Pain from third molars was the second most common reason for visiting the dental clinic (19.3%).

Use of Complementary and Alternative Therapies among Active Duty Soldiers, Military Retirees, and Family Members at a Military Hospital

OBJECTIVE

To survey soldiers, retirees, and spouses about their use and interest in complementary and alternative medicine (CAM) therapies.

METHODS

We used an anonymous, self-administered survey.

RESULTS

Of 291 completed surveys, 81% used one or more CAM therapy. The most commonly used were massage and herbal/food supplements. The most common reasons were pain, stress, and anxiety. In addition, 69% wanted CAM therapies offered at the medical treatment facility (MTF), whereas 24% would pay for the services, and 44% were undecided.

CONCLUSION

A high percentage of soldiers, retirees, and dependents are using CAM therapies and most would prefer that they be made available at the MTF. The implications of such high CAM usage within the military suggests a need for nurses and providers to become educated in CAM therapies to better assist patients in making appropriate choices between two very different forms of medical treatment options and for consideration to provide these services within the MTF.

Prostate Cancer Screening among Military Service Members

This retrospective study investigated the characteristic of military male beneficiaries age 50 years and older who were screened for prostate cancer at a medical center in the Pacific Regional Command. Data were collected on male patients who were seen in three adult outpatient clinics from December 1999 through November 2001. Two research questions were asked: What are the characteristics of men age 50 and older who were screened for prostate cancer? Are there variations in prostate cancer screening based on age, ethnicity, and military status? Data were analyzed using descriptive statistics. The sample was predominantly Caucasian and Asian/Pacific Islander who were over age 67. Although there was evidence of screening in 68% of the sample, 13% of the men had been screened according to the American Cancer Society's recommendations. The findings support the need for a prostate cancer screening policy for the Department of Defense.

Effects of maternal characteristics on cesarean delivery rates among U.S. Department of Defense healthcare beneficiaries, 1996-2002

BACKGROUND

National rates of cesarean birth continue a three decade-long escalation, despite widespread recognition that a reduction in the use of the procedure is a continuing appropriate public health goal, as evidenced by the Healthy People 2010 reduction targets. Nonclinical factors associated with cesarean delivery include maternal age, race, socioeconomic status, and insurance coverage. This study compared cesarean delivery rates and trends for the U.S. Department of Defense healthcare beneficiary population from 1996 to 2002 with those observed nationally, and assessed the association of these nonclinical factors with cesarean rate variation in the U.S. Department of Defense healthcare beneficiary population.

METHODS

Hospital discharge and claims records for babies born in the military and civilian hospitals that comprise the Department of Defense healthcare network were used to calculate total and primary cesarean delivery rates and vaginal birth after cesarean (VBAC) rates from 1996 to 2002. Annual cesarean rates for subgroups defined by maternal age, race, and socioeconomic status were calculated to examine rate variations and rate trends within the study population. Pooled data from 1999 to 2002 were used to compare rates across socioeconomic status, stratified by age and race. Statistical significance of the differences calculated for subgroups was assessed using chi-square.

RESULTS

Total and primary cesarean delivery rates among the U.S. Department of Defense population were lower than those reported nationally for every year examined. Cesarean delivery and VBAC rate trends in the national and Department of Defense populations were similar. Within the Department of Defense population, total cesarean delivery increased with increasing maternal age and was more highly associated with racial minorities relative to white women. The higher socioeconomic subgroup (defined as active duty, retired, and warrant officers and their families in this study) was generally associated with reduced cesarean delivery rates.

CONCLUSIONS

Cesarean deliveries are performed less frequently for the U.S. Department of Defense healthcare beneficiary population relative to the national population. Associations between socioeconomic factors and cesarean rates reported for the national population were not apparent in the study population. The consistent pattern of rate variation across racial subgroups in the Department of Defense population suggests that factors beyond those examined in this study are needed to explain the elevated cesarean rates for racial minorities.

[The 7th Field Hospital of the Army of the Czech Republic (ACR) in southern Iraq: statistics of professional activity and aspects of a foreign mission]

The short communication informs about the work of the field hospital in Iraq. From 3rd June till 10th September 2003 there were 123 patients operated on, 184 patients were hospitalized. The hospital exerted 1,194 bed-days, 131 of them at the intensive care unit. The outpatient department treated 6,953 patients. There were 824 X-ray and ultrasonographic examinations and the laboratory performed 7,941 tests. In their practice the physicians encountered a wide spectrum of surgical and non-surgical diagnoses. Other humanitarian activities (material, organization of transport of children to specialized care in the Czech Republic, blood donor activity) were an integral part of the work. The work in non-standard conditions was significantly complicated by the extreme climate and the high safety risk.

Smoking rates in the staff of a military field hospital before and after wartime deployment

In the past, high rates of cigarette smoking have been reported in the British Armed Forces. We conducted an anonymous questionnaire survey in the 623 employees and attached staff of 34 Field Hospital on their sixth week of deployment to Iraq, in the course of Gulf War II. Information was sought on smoking status before and during the deployment, and self-declared reasons for smoking. 556 questionnaires were returned (response rate 89%). The median age of respondents was 33.3 SD 7.9 years (range 18-62) and 61% were male. Before deployment the number of regular smokers was 160 (29%) but it had now risen by 52 to 212 (38%). Of the extra smokers 33 were restarting an old habit but 19 were first-timers. Moreover, those who were regular smokers before deployment increased their daily consumption from a mean of 15 cigarettes to 21. Smoking rates did not differ between clinical and non-clinical staff or between men and women; the rates were lower in officers than in non-officers, and in reservists than in regular Army personnel. The reasons most commonly cited for starting smoking or increasing consumption were boredom, social factors and stress. Few respondents could recall having received smoking-related health education during previous service with the military. Smoking rates in this medical unit increased substantially during the overseas deployment. There were no data on cigarette consumption after return to ordinary duties, so we cannot say whether these effects are short-term or long-term. However, even the pre-existing rate of 42% in regular army personnel is high enough to demand urgent action by an employer.
