REVIEW
Lianxiang Jiang, Meizhu Hu, Yan Lu, Ya Cao, Yan Chang, Zeping Dai
BACKGROUND: Intracranial lesions, trauma or surgery-related damage activate immune inflammation and neuroendocrine responses, causing ischemic brain injury. Studies have shown that inflammatory cascade mediated by neuroendocrine hormones and proinflammatory mediators is implicated in the pathophysiology of ischemic brain injury. Alpha2-adrenoceptor agonists, dexmedetomidine, is widely used as neuroprotectants in anesthesia practice. However, it is still lack of a comprehensive meta-analysis to evaluate the neuroprotection of dexmedetomidine against ischemic brain injury via suppressing these two physiological responses...

A mass casualty event can result in an overwhelming number of critically injured pediatric victims that exceeds the available capacity of pediatric critical care (PCC) units, both locally and regionally. To address these gaps, the New York City (NYC) Pediatric Disaster Coalition (PDC) was established. The PDC includes experts in emergency preparedness, critical care, surgery, and emergency medicine from 18 of 25 major NYC PCC-capable hospitals. A PCC surge committee created recommendations for making additional PCC beds available with an emphasis on space, staff, stuff (equipment), and systems...

BACKGROUND AND OBJECTIVE: Port wine stains (PWS) are congenital vascular malformations that progressively darken and thicken with age. Laser therapy is currently the most effective way in clinical practice for PWS. A 1,064 nm Nd:YAG laser in the near-infrared band can achieve a deeper treatment depth compared to the current widely adopted pulsed dye laser. However, because of its relatively weak absorption by blood, single-pulse Nd:YAG laser requires high energy density to cause effective vessel damage, but may inflict undesirable burning to surrounding collagen...

INTRODUCTION: Thermal ablation of tumors by Nd:YAG laser has been growing as a multidisciplinary subspecialty defined as laser-induced thermal therapy (LITT), and has been increasingly accepted as a minimally invasive method for palliation of advanced or recurrent cancer. Previous studies have shown that adjuvant chemotherapy can potentiate laser thermal ablation of tumors leading to improved palliation in advanced cancer patients. OBJECTIVE: Evaluate nephrotoxicity by early markers of renal function in treating head and neck cancer using intra-tumor injections of cisplatin combined with laser-induced thermal therapy (CDDP-LITT)...

BACKGROUND: Low-dose photodynamic therapy PDT (photoinduction) can modulate tumor vessels and enhance the uptake of liposomal cisplatin (Lipoplatin®) in pleural malignancies. However, the photo-induction conditions must be tightly controlled as overtreatment shuts down tumor vessels and enhances normal tissue drug uptake. MATERIAL AND METHODS: In a pleural sarcoma and adenocarcinoma rat model (n = 12/group), we applied photoinduction (0.0625 mg/kg Visudyne®, 10 J/cm(2) ) followed by intravenous Lipoplatin® (5 mg/kg) administration...

BACKGROUND AND OBJECTIVE: Nonmelanoma skin cancer (NMSC) is the most common human cancer. Because these tumors often affect the face, there is a strong need for both accurate removal of these neoplasms to prevent recurrence and maximal tissue preservation to prevent cosmetic or functional deformity. Polarization-enhanced reflectance and fluorescence imaging (PERFI) is a new bedside method that uses fluorescent chromophores to image NMSC. While the feasibility of the technique has been successfully demonstrated in ex vivo studies, this is the first pilot study to extend the use of PERFI to in vivo intraoperative imaging of NMSC...

BACKGROUND AND OBJECTIVE: Fractional CO2 laser therapy has been used to improve scar pliability and appearance; however, a variety of treatment protocols have been utilized with varied outcomes. Understanding the relationship between laser power and extent of initial tissue ablation and time frame for remodeling could help determine an optimum power and frequency for laser treatment. The characteristics of initial injury caused by fractional CO2 laser treatment, the rates of dermal remodeling and re-epithelialization, and the extent of inflammation as a function of laser stacking were assessed in this study in a porcine scar model...

Verrucae are benign epithelial proliferations, characteristically 1-20 mm in diameter, caused by human papilloma virus (HPV) infection occurring on the skin and mucosa (Photomed Laser Surg 33(6):338-42, 2015; Lasers Med Sci 29(3):1111-6, 2014). Prevalence of verrucae is 5-20% in children and young adults with peak incidence reported during teenage years (Lasers Med Sci 29(3):1111-6, 2014; J Am Acad Dermatol 22(4):547-66, 1990; J Korean Med Sci 24(5):889-93, 2009). Patients often express significant displeasure with quality of life due to this cosmetic insecurity, as well as functional problems and physical discomfort when they occur on palms of hands and soles of feet...
