BACKGROUND: Some studies have shown the beneficial effects of yoga for individuals with bronchial hyperreactivity with regard to (1) a reduction in the use of rescue medication, (2) an increase in exercise capacity, and (3) an improvement in lung function. Despite the fact that yoga is promising as a new treatment for pediatric patients, further studies are needed to assess the use of this training for asthma management. OBJECTIVE: This study was performed to assess the beneficial effects of yoga in exercise-induced bronchoconstriction (EIB) in children.

BACKGROUND: Osteopathic lymphatic pump treatments (LPT) are used to treat edema, but their direct effects on lymph flow have not been studied. In the current study, we examined the effects of LPT on lymph flow in the thoracic duct of instrumented conscious dogs in the presence of edema produced by constriction of the inferior vena cava (IVC). METHODS AND RESULTS: Six dogs were surgically instrumented with an ultrasonic flow transducer on the thoracic lymph duct and catheters in the descending thoracic aorta and in IVC.

The 'idiopathic' dacryostenosis has not yet been cleared up in its aetiological aspects. For further explanation of aetiology and pathomechanisms an experimental, anatomical study was made. Its object was to define the angles and measurements within the bony lacrimal structures and to establish possible connections between the development of the postsaccal stenosis and certain bony constellations of the lacrimal system.

Postoperative junctional ectopic tachycardia (JET) in children undergoing cardiac surgery is a serious arrhythmia that is associated with considerable morbidity and mortality. We present here a case of successful landiolol therapy for postoperative JET in a 3-month-old infant who underwent ventricular septal defect closure and right pulmonary artery plasty. His left ventricular function was poor postoperatively. The JET was refractory to amiodarone and caused severe hypotension, which was required cardiac massage.

OBJECTIVE: To determine whether lumen narrowing in vertebral arteries during atlanto-axial rotation is due to stretch or localized compression. DESIGN AND SETTING: Experiments with models were made in a private chiropractic clinic, whereas studies of cadaveric specimens were performed in an anatomy laboratory. Doppler ultrasound and magnetic resonance angiography (MRA) studies were carried out in the radiology department of a public hospital. PATIENTS: Eight patients had their vertebral arteries examined by use of a Doppler velocimeter and MRA.

OBJECTIVE: It has been proposed that Doppler velocimetry, which is noninvasive, quick, and relatively inexpensive, should be used when the screening vertebral arteries before manipulation to reduce the risk of cervical manipulation-related injury to these vessels. The objective of this analysis of the literature is to study the evidence of the suitability of Doppler velocimetry for this purpose.

OBJECTIVE: This case study describes a patient with long-standing rheumatoid arthritis of the cervical spine who presented with significant bone destruction, gross joint derangement, and a potentially life-threatening complication, basilar invagination with brain stem compression. The pathophysiology, clinical presentation, imaging, and surgical management are discussed. CLINICAL FEATURES: A 67-year-old female presented to a chiropractic clinic with chronic neck pain of 30 years of duration complicated by rheumatoid arthritis.

Dexmedetomidine, a selective alpha 2-adrenoceptor (α2AR) agonist, has provided significant analgesia in neuropathic pain. However, its underlying molecular mechanism has not been fully elucidated. In the present study, we found that intrathecal administration of dexmedetomidine alleviated mechanical allodynia induced by chronic constriction injury (CCI), and pretreatment with BRL44408 significantly reversed the dexmedetomidine-induced anti-nociceptive effect.
