Prevalence of Low Back and Cervical Back Pain in Military Helicopter Crews: An Underestimated Italian Problem.

BACKGROUND: Studies have highlighted the incidence and prevalence of chronic pain, which is an epidemic problem in all career sectors, as well as estimated the economic loss that follows its pathology. Several studies have indicated a high incidence of chronic osteoarticular pain in military service members, particularly in flight personnel. To date, no studies have estimated the incidence of pain pathology in the Italian military population, despite the implications related to flight qualification. METHODS: A survey was conducted on helicopter flight personnel undergoing periodic annual evaluation. RESULTS: A statistically significantly higher incidence of pain pathology than that reported in the global civilian population was demonstrated. More than 80% of the interviewed population reported moderate-to-severe back pain (45% in the lumbar tract and 38% in the cervical tract). Further, it was found that most staff with chronic pain do not use drugs or other treatments for severe pain because of concerns that such treatment approaches may compromise flight qualifications. DISCUSSION: The present study observed a high incidence of pain in Italian military flight personnel and examined the degree to which this problem is undertreated in these individuals. To address this problem, further in-depth and larger investigations that include therapeutic protocols to resolve such pain pathologies should be conducted. Such investigations could help to reduce pain experienced by flight personnel and enhance the productivity of the Italian military forces while considering the pharmacologic limitations related to the task. CONCLUSION: Chronic lumbar and neck pain is more common in military helicopter crews than in the civilian population. The true figure is frequently underestimated because of staff concerns regarding the potential influence of therapies on work activity.

High Prevalence of Spinal Magnetic Resonance Imaging Findings in Asymptomatic Young Adults (18-22 Yrs) Candidate to Air Force Flight.

STUDY DESIGN: Cross-sectional, retrospective, magnetic resonance (MR) imaging study, performed during cadets' selection procedures of the Italian Air Force Academy. OBJECTIVE: To assess the prevalence of spinal MR imaging findings in asymptomatic young adults (18-22 yrs) candidate to Air Force Flight. SUMMARY OF BACKGROUND DATA: Spinal MR imaging findings are frequently detected in asymptomatic subjects. Literature prevalence data come from studies that analyze different patient populations, in a wide age range and in different spinal tracts. Chronic degenerative disease of the vertebral column often occurs in pilots exposed to high flight acceleration forces, thus resulting crucial for Air Force Academy to exclude vertebral disease in cadets. METHODS: Three hundred fifty asymptomatic young adults underwent a 3T MR examination of the entire spine. A structured radiological report was set up to classify and calculate the prevalence of spinal MR imaging findings. RESULTS: Two hundred seventy of 350 subjects (77%) presented spinal MR findings, while 80 of 350 candidates (23%) had no detectable MR imaging findings. One hundred six of 350 (30%) candidates had at least one disc desiccation and 47 of 350 (13%) presented at least one disc narrowing. Disc bulging was found in 176 of 350 (49%) cadets. Sixty-two of 350 (18%) subjects showed disc protrusion while 28 of 350 (8%) had disc extrusion. Forty-five of 350 (13%) candidates presented low grade intervertebral spondylosis and of these 12 had also facet joints spondylosis. Asymptomatic vertebral fractures were observed in 2 of 350 (<1%) cadets. CONCLUSION: A high rate of MR spinal imaging findings, similar to that of the adult population, was detected in our population of young asymptomatic subjects. Our results suggest that the process of aging spine, which is supposed to begin in the second decade of life, is morphologically appreciable in the immediate postadolescent period and this issue is of crucial importance when selecting military pilots. LEVEL OF EVIDENCE: 4.

Discriminant and convergent validity of TEMPS-A[P] correlation with MMPI and the emotional-affective state following a stressful situation.

BACKGROUND: The temperament evaluation of the Memphis, Pisa, Paris and San Diego questionnaire (TEMPS), in its rater-wise and its self-evaluation forms, has been designed to evaluate temperamental characteristics in clinical and non-clinical populations. The validation process is currently in progress in various countries. In order to improve this validation process we have extended the area of correlations of its self-evaluation form (TEMPS-A[P]) to MMPI, and to a special RS that allows assessment of the emotional-affective state following a stressful situation. METHODS: In 693 candidates applying to become cadets in the Italian Air Force we have assessed the correlation between the TEMPS-A[P] and the MMPI validity and clinical scales, and administered an emotional-affective state questionnaire (EAS-RS) after they had gone through the stressful challenge of taking an academy entrance examination. RESULTS: As regards MMPI validity scales, TEMPS-A[P] depressive candidates tend to report their symptoms sincerely. Hyperthymic candidates tend to give false answers so that others will see them in a good light. Cyclothymic and irritable candidates tend to exaggerate symptoms. As regards the MMPI clinical scales, a low level of linkage between affective temperaments and abnormal personality traits was found. As regards EAS-RS: hyperthymic temperament on one hand, and cyclothymic and depressive temperaments on the other, are characterized by counter-polar emotional states following the test; these are desirable in the first case and undesirable in the other two. CONCLUSIONS: The convergent and discriminant validity of TEMPS-A[P] was confirmed. From a personalistic point of view, temperaments seem to belong to the realm of normality rather than to that of pathology, in line with their putative adaptive role.

TEMPS-A[p] temperament profile related to professional choice: A study in 1548 applicants to become a cadet officer in the Italian air force.

BACKGROUND: Temperaments have been described with respect to their adaptive roles. Thus, depressive traits seem to increase sensitivity to suffering, cyclothymic traits appear relevant to creativity, and hyperthymic traits have been implicated in territoriality and leadership and more generally in active pursuits. METHODS: The temperaments of 1548 candidates applying to become a cadet officer in the Italian air force, who had taken the 2005 entrance examination, were compared with deviant and non-deviant peers. At a psychological level, we also compared those who had applied to become a cadet officer with other applicants who had failed in a previous entrance examination and with applicants who had passed or failed to pass the specific psychological entrance examination. RESULTS: Applicants who took the entrance examination are more hyperthymic than their peers, regardless of any concurrent psychosocial deviance (i.e. drug addiction). The specificity of this correlation is confirmed by the fact that applicants who made a second attempt to pass the entrance examination after an initial failure were more hyperthymic than first-time applicants. Similarly, success in specific psychological admission tests is related to the same temperamental profiles, since those who prove to be psychologically fit are more hyperthymic. The inverse relationship emerges from an examination of other temperamental scales, which are better represented in controls (non-applicants), or other applicants making their first attempt at admission, or those who were excluded due to psychological flaws. CONCLUSION: In the present study, extremely high scores on the hyperthymic scale combined with extremely low ones in the cyclothymic scale seem to correspond to the specific temperament profile and to the highest likelihood of success in those applying to become a cadet officer in the Italian air force.

The relationship between facial skeletal class and expert-rated interpersonal skill: an epidemiological survey on young Italian adults.

BACKGROUND: The facial region plays a major role in determining physical attractiveness, so we assessed the hypothesis that the capability of successfully managing interpersonal relationships in young adults might be related to the facial skeletal class. METHODS: 1,014 young subjects applying to the Military Academy of Pozzuoli, Italy, were enrolled and the cephalometric evaluation was performed by calculating the angular relationships between skeletal points localized by the lateral cephalogram of the face, sorting the subjects in three groups corresponding to each major facial skeletal class. Concurrently, the subjects were evaluated by a team of psychiatrists administering the MMPI-2 test followed by a brief colloquium with each candidate, in order to identify those subjects characterized by low skills for managing interpersonal relationships. RESULTS: According to the psychiatric evaluation about 20% of the subjects were considered potentially unable to manage successfully interpersonal relationships (NS). Males displayed an about two-fold increased risk of being NS. No differences were shown in the distribution of the NS male subjects among the three different facial skeletal classes. On the other hand, NS females displayed a different distribution among the three facial skeletal classes, with a trend of about two-fold and four-fold, respectively, for those subjects belonging to classes II and III, respect to those belonging to class I. CONCLUSION: Females may be more sensitive to physical factors determining beauty, such as the facial morphology certainly is. This finding appears to be interesting especially when thinking about possible orthodontic interventions, although further study is certainly needed to confirm these results.
