1.  Infrared venography of the hand in Apert syndrome 
As well as craniofacial synostosis, complex syndactyly of hands is a distinctive feature of Apert syndrome. Consideration of blood flow to the digits is very important in separation surgery. Several reports offer information about arterial distribution in Apert's hands. Though, venous pattern has not been well discussed. Infrared venography offers a real-time image with minimal invasion. An Apert syndrome patient underwent a series of finger splitting surgeries. Infrared venography was carried out to assess veins. There was a palmar venous arch, placing distally to the metacarpophalangeal joint. The arch had to be cut to divide fused fingers sufficiently. As well as arterial abnormality, venous uniqueness should be noted in Apert syndactyly surgeries. Infrared venography, which can be carried out easily, offers good information that surgeon require.

2.  Comparative Study of Antibacterial Effects and Bacterial Retentivity of Wound Dressings 
Eplasty  2013;13:e5.
Objectives: We are often confused on selecting a suitable wound dressing for the treatment of infected wounds from huge number of available wound dressings. Then, to help clinicians easily select a wound dressing, we compared the antibacterial effects and bacterial retentivity (ie, potency of keeping absorbed bacteria inside wound dressings and preventing them from leaking out) of wound dressings. Methods: Five wound dressings with antibacterial constituents were compared to research antibacterial effects against nonpathogenic Escherichia coli using an in vitro model. The 5 other wound dressings with no antibacterial constituent were compared to research bacterial retentivity. The relative amount of E coli was determined using cell proliferation reagent WST-1 (11644807001, Roche Applied Science, United States) with time. Results: The results have shown that the antibacterial effects and bacterial retentivity differed among various wound dressings. Silver ions quickly exerted a very strong antibacterial effect, and hydrofibers had a high potency of bacterial retentivity by gelling the absorbed bacteria in wound dressings. Conclusions: The present study indicated the differences of antibacterial strength, time of onset and duration of the antibacterial effect, and bacterial retentivity between each wound dressing. Clinicians should use appropriate wound dressings according the wound condition in consideration of the different characteristics of wound dressings. The present results are helpful for clinicians to select appropriate wound dressing.

3.  Supplementation of bone marrow aspirate-derived platelet-rich plasma for treating radiation-induced ulcer after cardiac fluoroscopic procedures: A preliminary report 
Background:
The frequency of encountering radiodermatitis caused by X-ray fluoroscopic procedures for ischaemic heart disease is increasing. In severe cases, devastating ulcers with pain, for which conservative therapy is ineffective, emerge. Radiation-induced ulcers are notorious for being difficult to treat. Simple skin grafting often fails because of the poor state of the wound bed. A vascularized flap is a very good option. However, the non-adherence of the well-vascularized flap with the irradiated wound bed is frequently experienced.
Aim:
To ameliorate the irradiated wound bed, bone marrow-derived platelet-rich plasma (bm-PRP) was delivered during the surgery.
Materials and Methods:
Four patients with severe cutaneous radiation injury accompanied by unbearable pain after multiple fluoroscopic procedures for ischaemic heart disease were treated. Wide excision of the lesion and coverage with a skin flap supplemented with bm-PRP injection was performed.
Results:
All patients obtained wound closure and were relieved from pain. No complication concerning the bone marrow aspiration and delivery of bm-PRP was observed.
Conclusions:
Supplementation of bm-PRP can be an option without major complications, time, and cost to improve the surgical outcome for irradiated wounds.

4.  bFGF Regulates PI3-Kinase-Rac1-JNK Pathway and Promotes Fibroblast Migration in Wound Healing 
PLoS ONE  2010;5(8):e12228.
Fibroblast proliferation and migration play important roles in wound healing. bFGF is known to promote both fibroblast proliferation and migration during the process of wound healing. However, the signal transduction of bFGF-induced fibroblast migration is still unclear, because bFGF can affect both proliferation and migration. Herein, we investigated the effect of bFGF on fibroblast migration regardless of its effect on fibroblast proliferation. We noticed involvement of the small GTPases of the Rho family, PI3-kinase, and JNK. bFGF activated RhoA, Rac1, PI3-kinase, and JNK in cultured fibroblasts. Inhibition of RhoA did not block bFGF-induced fibroblast migration, whereas inhibition of Rac1, PI3-kinase, or JNK blocked the fibroblast migration significantly. PI3-kinase-inhibited cells down-regulated the activities of Rac1 and JNK, and Rac1-inhibited cells down-regulated JNK activity, suggesting that PI3-kinase is upstream of Rac1 and that JNK is downstream of Rac1. Thus, we concluded that PI3-kinase, Rac1, and JNK were essential for bFGF-induced fibroblast migration, which is a novel pathway of bFGF-induced cell migration.

5.  Human Chorionic Gonadotropin Combined with Progesterone for Luteal Support Improves Pregnancy Rate in Patients with Low Late-Midluteal Estradiol Levels in IVF Cycles 
Purpose: To investigate how late-midluteal estradiol levels relate to the pregnancy outcome in IVF cycles, and to assess whether human chorionic gonadotropin (hCG) for luteal support benefits the pregnancy outcome of patients with low late-midluteal estradiol levels.
Methods: The pregnancy rate of 436 women undergoing first IVF cycles with long protocol and luteal support with progesterone alone were analyzed. Unsuccessful women with low late-midluteal estradiol levels (<100 pg/mL) proceeded with the exploratory second IVF cycles where they were randomly given with either progesterone alone (P protocol) or hCG +progesterone (P+hCG protocol) for luteal support.
Results: Pregnancy rate in women with low late-midluteal estradiol levels was significantly lower compared to that with medium (100–500 pg/mL) and high (>500 pg/mL) levels (13.3, 26.8, and 36.3%, respectively). P+hCG protocol increased late-midluteal estradiol levels and produced a significantly higher pregnancy rate (31.7%) than P protocol (13.7%).
Conclusions: hCG in combination with progesterone for luteal support was suggested to benefit women undergoing IVF with low late-midluteal estradiol levels.
