BACKGROUND Approximately 6% to 8% of lumbar pain cases, whether associated with radicular pain or not, may be attributed to the presence of piriformis muscle syndrome. Available treatments, among others, include pharmacotherapy, physical therapy, and injections of different substances into the muscle. Various methods have been used to confirm correct needle(More)
OBJECTIVE Botulinum toxin is a neurotoxin that has been widely used in chronic pain for the treatment of multiple conditions with a component of localized muscle spasm. Recent studies suggest that botulinum toxin is effective in the treatment of neuropathic pain syndromes such as postherpetic neuralgia or painful scars. METHODS We searched the PubMed and(More)

Recent studies suggest that botulinum toxin is effective in the treatment of neuropathic pain syndromes such as post-herpetic neuralgia. CASE REPORT We report the case of a 67-year-old man(More)
OBJECTIVES Buerger disease (or thromboangeiitis obliterans) is an inflammatory disease of the medium and small caliber arteries and veins that predominantly affects young males and presents with ischemia in the hands or the feet. It is closely associated with smoking. Critical ischemia of the lower limbs is a threat to the survival of the patient s(More)
BACKGROUND AND PURPOSE Pentoxifylline exhibits rheological properties that improve microvascular flow and it is widely used in vascular perfusion disorders. It also exhibits marked anti-inflammatory properties by inhibiting tumour necrosis factor alpha production. Thiopental is one of the most widely used drugs for rapid induction of anaesthesia. During(More)
BACKGROUND AND GOALS Mechanical ventilation (MV) can induce or worsen pulmonary oedema. Aquaporins (AQPs) facilitate the selective and rapid bi-directional movement of water. Their role in the development and resolution of pulmonary oedema is controversial. Our objectives are to determine if prolonged MV causes lung oedema and changes in the expression of(More)
NEW FINDINGS What is the central question of this study? Although different studies have attempted to find factors that influence the expression of aquaporins (AQPs) in the lung in different situations, to date no research group has explored the expression of AQP1 and AQP5 jointly in rats mechanically ventilated with different tidal volumes in a model of(More)
Martorell ulcer is a specific disease entity characterized by multiple small homogeneous, symmetrical lesions, although single lesions are observed as well, most commonly located on the anterolateral aspect of the lower leg. The pain associated to these lesions is disproportionate to their size.Martorell ulcer designates a specific disease entity that(More)
