Tratamiento domiciliario de gonartrosis con parches de microcorrientes

Objective: To outline the treatment by patches of microcurrent at home of patients with disabling knee osteoarthritis to perform their activities of daily life and work. Material and methods: We selected 80 patients in the surgical waiting list for total knee arthroplasty. 40 of whom received active patch and 40 inactive. All were given exercise protocol knee. The variables analyzed were: pain (VAS), joint balance, muscular balance and quality of life (SF-12). Patients were reviewed after two months of treatment. Variables were analyzed with SPSS 17.0 statistical program. Results: Statistically significant results were obtained (p <0.05) for decrease in mean pain according to VAS scale. No significant differences for other variables were found. Conclusions: Microcurrent therapy could be an alternative in the treatment of knee osteoarthritis pain, with no differences with the traditional treatment.

Tratamiento farmacológico de la EPOC estable

Pharmacological treatment of patients with stable COPD should be individualised. Inhaled bronchodilators are the mainstay of pharmacological treatment for COPD. Long-acting medications (LABA or LAMA) are recommended over short-acting agents (SABA or SAMA). Short-acting bronchodilators are used on demand to rapidly control symptoms regardless of level of severity. Long-acting bronchodilators are used as maintenance therapy and are the mainstay of treatment in patients with permanent symptoms. Initial treatment for COPD is monotherapy with a long-acting bronchodilator. Clinical practice guidelines do not specify the best bronchodilator to use. The choice should be made on an individual basis, taking into account the patient’s preferences, response to treatment, its potential side effects and cost. When monotherapy fails to control symptoms, the first recommended step is to check medication adherence, inhaler technique and adequacy of inhalation device, and if these are correct but monotherapy is still insufficient, treatment should be intensified with combined inhaled therapies. Most clinical practice guidelines recommend the use of long-term therapy with LABA+inhaled corticosteroids in patients who experience frequent exacerbations and with FEV1 <50%. Long-term monotherapy with inhaled corticosteroids or oral corticosteroids is not recommended, and neither is the regular use of mucolytics nor the use of roflumilast.

Structural and metamorphic evolution of the northern Himachal Himalaya, NW India - (Spiti-eastern Lahul-Parvati valley traverse)

The Himalayan orogen is the result of the collision between the Indian and Asian continents that began 55-50 Ma ago, causing intracontinental thrusting and nappe formation. Detailed mapping as well as structural and microfabric analyses on a traverse from the Tethyan Himalaya southwestward through the High Himalayan Crystalline and the Main Central Thrust zone (MCT zone) to the Lesser Himalayan Sequence in the Spiti-eastern Lahul-Parvati valley area reveal eight main phases of deformation, a series of late stage phases and five stages of metamorphic crystallization. This sequence of events is integrated into a reconstruction of the tectonometamorphic evolution of the Himalayan orogen in northern Himachal Pradesh. The oldest phase D-1 is preserved as relies in the High Himalayan Crystalline. Its deformational conditions are poorly known, but the metamorphic evolution is well documented by a prograde metamorphism reaching peak conditions within the upper amphibolite facies. This indicates that D-1 was an important tectonometamorphic event including considerable crustal thickening. The structural, metamorphic and sedimentary record suggest that D-1 most probably represents an early stage of continental collision. The first event clearly attributed to the collision between India and Asia is documented by two converging nappe systems, the NE-verging Shikar Beh Nappe and the SW-verging north Himalayan nappes. The D-2 Shikar Beh Nappe is characterized by isoclinal folding and top-to-the NE shearing, representing the main deformation in the High Himalayan Crystalline. D-2 also caused the main metamorphism in the High Himalayan Crystalline that was of a Barrovian-type, reaching upper amphibolite facies peak conditions. The Shikar Beh Nappe is interpreted to have formed within the Indian crust SW of the subduction zone. Simultaneously with NE-directed nappe formation, incipient subduction of India below Asia caused stacking of the SW-verging north Himalayan Nappes, that were thrust from the northern edge of the subducted continent toward the front of the Shikar Beh Nappe. As a result, the SW-verging folds of the D-3 Main Fold Zone formed in the Tethyan Himalaya below the front of the north Himalayan nappes. D-3 represents the main deformation in the Tethyan Himalaya, associated with a greenschist facies metamorphism. Folding within the Main Fold Zone subsequently propagated toward SW into the High Himalayan Crystalline, where it overprinted the preexisting D-2 structures. After subduction at the base of the north Himalayan nappes, the subduction zone stepped to the base of the High Himalayan Crystalline, where D-3 folds were crosscut by SW-directed D-4 thrusting. During D-4, the Crystalline Nappe, comprising the Main Fold Zone and relies of the Shikar Beh Nappe was thrust toward SW over the Lesser Himalayan Sequence along the 4 to 5 kms thick Main Central Thrust zone. Thrusting was related to a retrograde greenschist facies overprint at the base of the Crystalline Nappe and to pro-grade greenschist facies conditions in the Lesser Himalayan Sequence. Simultaneously with thrusting at the base of the Crystalline Nappe, higher crustal levels were affected by NE-directed D-5 normal extensional shearing and by dextral strike-slip motion, indicating that the high-grade metamorphic Crystalline Nappe was extruded between the low-grade metamorphic Lesser Himalayan Sequence at the base and the north Himalayan nappes at the top. The upper boundary of the Crystalline Nappe is not clearly delimited and passes gradually into the low-grade rocks at the front of the north Himalayan nappes. Extrusion of the Crystalline Nappe was followed by the phase D-6, characterized by large-scale, upright to steeply inclined, NE-verging folds and by another series of normal and extensional structures D-7+D-8 that may be related to ongoing extrusion of the Crystalline Nappe. The late stage evolution is represented by the phases D-A and D-B that indicate shortening parallel to the axis of the mountain chain and by D-C that is interpreted to account for the formation of large-scale domes with NNW-SSE-trending axes, an example of which is exposed in the Larji-Kullu-Rampur tectonic window.
