The communication among international microsurgeons have switched from one direction (from paper, textbook) to multiway interactions through the internet. The authors believe the online platform will play an immensely important role in the learning and development in the field of microsurgery.

The high incidence of brain metastasis and the comparison of metastatic and non-metastatic phenotypes indicate an active crosstalk of brain metastatic breast cancers with the BBB. Certain miRNAs and serpins are regulatory molecules in defining the metastatic potential of breast cancers. Targeting these factors that favor the metastatic microenvironment may provide future therapeutic interventions for the brain metastasis of breast cancers.

The author concerns that long-term application of biologics will destroy the natural balance, and argues to rethink about small molecules that can restore immune homeostasis, thereby naturally correcting overproduced proinflammatory cytokines, as a strategy of new drug development against psoriasis and other autoimmune disorders.

The authors reviewed the MDCT images to show the number of lymph nodes superior to the saphenofemoral junction. In this study, on average, 3.67 nodes existed. However, there were 4 percent of cases with no countable nodes. This result indicates that appropriate preoperative screening is needed for this procedure.

Pedicled anterolateral thigh flap is a versatile option for reconstruction of complex soft tissue defects in varied anatomical regions. Its wide arc of rotation and less donor site morbidity are its added advantages.

The 2nd instructional course for adult brachial plexus injuries is a fantastic opportunity to meet and learn from experts in the field. We cordially invite you to visit Chang Gung Memorial Hospital to participate in this unique learning experience.

Health care systems in many countries are confronted with increasing economic limitations. Thus, complex microsurgical procedures and extensive rehabilitation programs are poorly compensated. However, this case demonstrates a dramatic reduction of socioeconomic expenses by allowing a potential radiocarpal amputee to return to work for another estimated 30 years.

Authors reported a case of cholesteatoma that mimicked facial neurinoma. To avoid confusion in such cases, diffusion-weighted MRI may be useful in preoper-ative differential diagnosis.

Division of the lateral plantar artery does not jeopardize the foot circulation because of anastomosis of the lateral plantar artery with the dorsalis pedis artery at the first intermetatarsal space. However, care should be taken with patients with peripheral artery occlusive disease and the flow of dorsalis pedis artery should be confirmed before surgery. Given the advantages of sizable vessel, easy dissection, and proximity to the defect, we believe that the lateral plantar artery might be a valuable option as recipient vessel for lateral plantar forefoot reconstruction.

This case report shows the effectiveness of Apremilast in refractory ophiasis AA with a rapid and highly scalp-hair regrowth with a cosmetically important response.
