Rheumatoid arthritis (RA) primarily affects the synovial joints; it is a systemic autoimmune inflammatory disorder. Swan neck deformity (SND) is an articular manifestation of RA; its association with seropositive RA is well documented. We present a thirty-nine-year-old Bahraini male with seropositive RA-associated SND. At the time of diagnosis in 2015, the patient presented with morning stiffness, 3rd and 4th metacarpophalangeal (MCP) joints pain, tenderness of the left hand and bilateral 3rd and 4th proximal interphalangeal (PIP) joint pain and swelling for two months. Laboratory investigations revealed positive rheumatoid factor (RF) and C-reactive protein (CRP) only. The patient was diagnosed as seropositive RA. The patient w as treated with weekly 12.5 mg methotrexate (MTX) injection and folic acid 5 mg. The patient was lost for follow-up for two years and returned with hand deformity, prominent SND of 3rd and 4th fingers bilaterally. Laboratory investigations revealed: antinuclear antibody (ANA) (1:160), RF (64 IU), anti-cyclic citrullinated peptide (anti-CCP) (356) and CRP (13). The patient was started on Humira (Adalimumab) injection 40 mg SC every two weeks plus MTX 10 mg weekly. Humira therapy dramatically improved laboratory and clinical signs of SND. In RA-associated SND, early detection and initiation of Humira biological therapy are essential in stopping the progression of the disease.

Energy storage devices are very popular in systems with the presence of renewable-based power generation. However, inappropriate usage of them may lead to aging and also the early failure of such systems. The factors affecting the aging of the batteries as the main energy storage devices in electrical systems are frequent changes in charging and discharging status, deep discharge, and a large number of power transactions in a short time. Furthermore, the development of microgrids (MGs) in distribution networks (DNs), leads to more complicated structures known as multi-microgrid (MMG) systems. In this paper, the day-ahead scheduling for the MMG system considering the degradation cost of the energy storage systems has been proposed. To model the uncertainties, chance-constrained programming (CCP) approach has been employed. The CCP helps the system operator to make better decisions without jeopardizing the system security. The degradation cost has been designed in a way that in the energy management process, misuse of the batteries is avoided. A hierarchical three-stage energy management process is designed. First, deterministic equivalents for the CCP problem are made and using these equivalents, in the first stage, MGs perform local scheduling and in the second stage, again considering deterministic equivalents of the CCP, DN performs global management and finally, MGs perform a rescheduling. Simulations with four case studies on a modified version of the IEEE 33-bus test system have shown the effectiveness of the proposed scheduling framework. The results show that decreasing confidence level in CCP decreases the system operational costs, however, threatens the system stability. Also, considering the battery degradation cost prevents the system operator from misapplication of the battery energy storage systems.
