Cutaneous Rosai-Dorfman disease (RDD) is a rare, benign condition mainly affecting the lymph nodes and sometimes involving the skin. RDD is notorious for its poor response to medication, and surgery is often the preferred treatment option for limited lesions. Herein, we present a case of cutaneous RDD in a 49-year-old woman with multiple facial nodules that showed minimal response to treatment with steroids, isotretinoin, and methotrexate. The diagnosis of cutaneous RDD was confirmed based on histopathological examination. The patient showed minimal response to medication; however, electrosurgery resulted in a relatively good cosmetic response. The present case demonstrates that electrosurgery can be an effective treatment option for cutaneous RDD, especially in case of patients with multiple lesions. The rarity of this disease and the limited reports on its management highlights the need for further research on the efficacy of different surgical modalities for cutaneous RDD.

The West African Power Pool is currently developing the regional electricity market for its member states. As the basic design for the cross-border power trading system for the West African Power Pool, the step-by-step evolution, the Baseline System and the Fullscale System, is estimated. Along with the interconnection project between member countries, the various functions from the data acquisition and processing by the Baseline System to the interchange trading by the Fullscale System will be implemented gradually.
A 17.5-fJ/bit Energy-Efficient Analog SRAM for Mixed-Signal Processing
Jinsu Lee,Dongjoo Shin,Youchang Kim,Hoi-Jun Yoo IEEE 2017 IEEE transactions on very large scale integration Vol.25 No.10
<P>An energy-efficient analog SRAM (A-SRAM) is proposed to eliminate redundant analog-to-digital (A/D) and digital-to-analog (D/A) conversion in mixed-signal systems, such as neuromorphic chips and neural networks. D/A conversion is integrated into the SRAM readout by charge sharing of the proposed split bitline (BL). Also, A/D conversion is integrated into the SRAM write operation with the successive approximation method in the proposed input-output block. Also, a configurable SRAM bitcell array is proposed to allocate the converted digital data without unfilled bitcells. The multirow access decoder selects multiple bitcells in a single column and configures the bitcell array by controlling the BL switches to split BLs. The proposed A-SRAM is implemented using the 65-nm CMOS technology. It achieves 17.5-fJ/bit energy-efficiency and 21-Gbit/s throughput for the analog readout, which are 64% and 1.3 times better than those of the conventional SRAM followed by a digital-to-analog converter (DAC). Also, the area is reduced by 91% compared with the conventional SRAM with analog-to-digital converter (ADC) and DAC.</P>
