BACKGROUND: People with neck pain (NP) experience sensorimotor and oculomotor deficits thought to be due to abnormal cervical afferent input. Convergence insufficiency (CI) measured by near point convergence (NPC) may be a feature in NP and neck torsion might help to differentiate a cervical cause. OBJECTIVES: This study aimed to investigate repeatability and reliability of NPC in neutral and torsion and compare between idiopathic NP and controls along with correlation to the Convergence Insufficiency Symptom Survey (CISS)...

BACKGROUND: This study was conducted to evaluate the effects of yogic practice on resting metabolism and redox status. METHODS: The study was conducted on 64 physically trained male volunteers selected randomly at the Air Force Academy. The yoga group (n = 34) practiced yogasana, pranayama, and meditation for 3 months (February-May 2011) and the control group (n = 30) performed physical training. Antioxidant variables in blood samples along with physiological parameters were estimated before and after 3 months...

OBJECTIVE: To further evaluate the efficacy and toxicity of the gamma-ray stereotactic body radiation therapy (SBRT) in patients with stage I/II non-small-cell lung cancer (NSCLC). METHODS: Twenty-nine newly diagnosed patients with stage I/II NSCLC who had no previous treatments, underwent OUR-QGD type of the gamma-SBRT at the Radiation Oncology Department, People's Liberation Army Airforce General Hospital, Beijing, China from January 2007 to July 2010. All patients were immobilized by vacuum bag, and then a slow CT scan was performed without any respiration gating...

The objective of the study was to analyse the influence of the shape and material of the military footwear worn by soldiers on muscle activity in the lower extremities, and whether such footwear could explain specific strain complaints and traumatic lesions in the region of the lower extremities.37 soldiers (one woman, 36 men) aged between 20 and 53 years underwent a dynamic electromyography (EMG) analysis. Wearing - one pair at a time - five different types of shoes, the subjects were asked to walk on a treadmill, where an EMG of the following muscles was taken: M...

Abstract Recent research on the relationship between cognition and affect suggests the prediction that psychological stress encourages stereotyping. Yet the empirical evidence regarding this proposition is inconclusive. This study examined the effect of stress on the perception of illusory correlations, which comprise a particular manifestation of stereotypic attributions, and the moderating role of tolerance of ambiguity. It was predicted, specifically, that the effect of stress on stereotyping will be more pronounced in persons who have a low tolerance of ambiguity than in persons tolerating ambiguity, who generally experience less stress...

BACKGROUND: The issue of atopy and increased serum IgE in IgA deficiency is still a matter of debate. The aim of this study was to evaluate the prevalence of IgA deficiency and its relationship with respiratory atopy. MATERIALS AND METHODS: A retrospective study on 4700 consecutive young males (age range 18-23), who underwent a health screen for admission to the Italian Airforce Academy between 1993 and 1995 was conducted. Serum IgA was measured by immunoturbidimetry and total and specific IgE by fluorescent enzyme immunoassay (Phadiatop FEIA, Pharmacia Cap System)...

A 12-month trial with telemedicine was conducted at two remote health centres located on Greek Islands, namely Lemnos and Skyros, where combat units of the Greek Airforce are situated. The units' medical services are supported by the 251st Central Hospital of the Greek Airforce in Athens, via a PC-based ISDN videoconferencing link, connected at 384 Kbps. Thirty-eight patients were recruited for the trial. A cost minimisation analysis was undertaken, for comparing the costs of telemedicine to those of hospital referrals, where patients from remote areas travelled to the hospital for consultation...

The practice of neurosurgery in a war zone provides enormous challenges and risks for the individual surgeon working in such an austere and hostile environment, but also provides a unique opportunity to treat a high volume of severe penetrating and blast injuries to the head, neck and the spine. The purpose of this article is to present the author's personal experiences and perspective as a military neurosurgeon working in the US Airforce Hospital in Balad (the 332nd Expeditionary Medical Group) Iraq in for 3 months in 2004...

BACKGROUND: Problems of low back and neck pain are were important for persons, who decided to participate in sport or to educate and work in jobs requiring high accelerations and loads. The aim of the study was evaluate a structure the whole spine on magnetic resonansce imaging among airforce candidates. MATERIAL AND METHODS: MRI of 98 young, healthy persons, with no abnormalities in structure and function of musclosceletal system, were analysed. RESULTS: Analysed material revealed dehydratation of intervertebral discs L4-L5 and L5-S1 among 23 persons (23...

BACKGROUND: Despite the claims that umbilical hernia (UH) is common among Nigerian children, the socio-economic class-related prevalence or incidence rate of UH in the Nigerian children is not known. We therefore undertook this study to determine the prevalence of UHs among Nigerian children of high socio-economic class. PATIENTS AND METHODS: This 7- years prospective study assessment of the prevalence of primary umbilical hernias among a private school admission seeking Nigerian children...

Recognition of thrombosis as a complication of exposure to high altitude has stimulated interest in rheological changes resulting from hypobaric hypoxia. Previous studies of platelet counts at high altitude have yielded conflicting results and have not been studied in conjunction with potential mediating cytokines. We studied the effects of high-altitude exposure on platelet numbers, thrombopoietin (tpo) and erythropoietin (epo) levels in man. A group of 28 volunteers from the Bolivian Airforce stationed at Santa Cruz (600 m altitude) were studied 48 h and 1 week after their ascent to La Paz (3600 m)...

Recent lipid intervention studies led to the implementation of lipid lowering therapy in the cardiovascular risk management. These secondary as well as primary prevention studies share the effect of HMG-CoA-reductase inhibition. Despite varying product properties there seem to be no major differences in risk reduction between the drugs. One could argue the main action of the statins, lipid lowering, is the most prominent mode of action. A new study (AirForce/Texas Coronary Atherosclerosis Prevention Study) extended that to patients with relatively low total cholesterol levels (mean 221 mg/dl with a slightly lowered LDL-C of 37 mg/dl, LDL-C of 150 mg/dl) successfully treated with lovastatin in primary prevention...

Lowering of LDL-cholesterol by 25 to 30% with statins resulted in a highly significant reduction of coronary event rates in 2 large primary prevention trials. In the West of Scotland Primary Prevention Study (WOSCOPS) hypercholesterolemic asymptomatic men were treated with either 40 mg of pravastatin or placebo, in the Airforce/Texas Coronary Atherosclerosis Prevention Study (AFCAPS/TexCAPS) 6605 men and women with average levels of LDL-cholesterol and low levels of HDL-cholesterol were treated with either 20 to 40 mg of lovastatin or placebo...

We compared the efficacy of the state form of the MAACL-R (Zuckerman & Lubin, 1985) in predicting success in Air Force basic training. Results of discriminant functions analyses showed that the Anxiety, Depression, Hostility, Positive Affect, and Sensation Seeking scales of the state MAACL-R efficiently predicted success in basic training. The need to incorporate state measures into studies of prediction is discussed.
