We used mouse soleus in vitro (n = 30) and canine gastrocnemius-plantaris preparations (n = 20) pump-perfused at the animal's blood pressure to establish if free radicals contribute to fatigue in oxidative skeletal muscle. The soleus from each leg contracted for 200 ms (70 Hz) once every minute for
Local cutaneous heating causes vasodilation as an initial first peak, a nadir, and increase to plateau. Reactive oxygen species (ROS) modulate the heat plateau in healthy controls. The initial peak, due to C-fiber nociceptor-mediated axon reflexes, is blunted with local anesthetics and may serve as
To assess the utility and tolerability of thiopurine-allopurinol co-therapy in inflammatory bowel disease (IBD) patients with intolerance to thiopurine monotherapy.
A retrospective observational study assessed cases of thiopurine intolerance then switched to thiopurine allopurinol co-therapy between
The role of eosinophilia in connective tissue diseases and the relationship between symptoms of rheumatic disease and eosinophilia have not been clearly established. The purpose of the present study was to explore the prevalence of eosinophilia in rheumatologic disease and determine its relationship
Spontaneous tumor lysis syndrome is a rare oncological emergency associated with multiorgan failure. It is characterized by an elevation of uric acid, hyperphosphatemia, hypocalcemia, hyperkalemia and renal failure in the setting of no active chemotherapy as a result of lysis of massive tumor
We describe a 66-year-old woman hospitalized with fever, fatigue and hepatopathy. In her medical history arterial hypertension (treated with propranolol and lisinopril), diabetes mellitus type 2 (no treatment before admission) and a gout arthropathy were noted wherefore a therapy with allopurinol
Leishmaniasis is a zoonotic parasitosis caused by a diphasic protozoan of the genus Leishmania. The dogs are considered the main domestic reservoir of L. infantum and its transmission occurs mainly through sand flies. We report the case of a 10 yr old Italian Segugio dog in Mar 2016
In healthy population, uric acid comprises the major component of 10-20% of renal stones. Extreme hiperuricaemia is seen in cancer patients with tumour lysis syndrome (TLS) which is classically associated with haematological malignancies with rapid tumour growth rates such as acute lymphoid
Acute ischaemia-reperfusion disrupts capillary fine structure and increases leukocyte adhesion in postcapillary venules. We determined whether chronic muscle ischaemia has similar consequences, and whether it is possible to ameliorate its effect on muscle performance. Following ischaemia (unilateral
A 56-year-old woman with a new diagnosis of metastatic pancreatic cancer presents to the emergency room with generalised fatigue. The patient is afebrile, however, hypotensive and tachycardic. Physical examination shows diffuse lymphadenopathy. Initial laboratory tests indicate that the patient has
Recent evidence indicates that hypoxia enhances the generation of oxidants. Little is known about the role of free radicals in contractility of the rat diaphragm during hypoxia. We hypothesized that antioxidants improve contractility of the hypoxic rat diaphragm and that xanthine oxidase (XO) is an
Acute tumor lysis syndrome (ATLS), a condition which results from a rapid destruction of tumor cells with massive release of cellular breakdown products, has been well described following the treatment of various malignancies. However, only a handful of cases of spontaneous ATLS have been reported
KEY POINTS AND PRACTICAL RECOMMENDATIONS: • Although chlorthalidone and hydrochlorothiazide are structurally similar, they are very different pharmacokinetically, with chlorthalidone having both an extremely long half-life (approximately 40 to 60 hours) and a large volume of distribution, with
