Mass casualty incidents (MCIs) are becoming more frequent worldwide, especially in the Middle East where violence in Syria has spilled over to many neighboring countries. Lebanon lacks a coordinated prehospital response system to deal with MCIs; therefore, hospital preparedness plans are essential to deal with the surge of casualties. This report describes our experience in dealing with an MCI involving a car bomb in an urban area of downtown Beirut, Lebanon. It uses general response principles to propose a simplified response model for hospitals to use during MCIs...

BACKGROUND AND OBJECTIVES: Melasma is a common acquired, chronic hypermelanosis and still remains a therapeutic challenge. The low-fluence 1 064 nm Q-switched Nd:YAG laser is the most widely used for the treatment of moderate to severe melasma in Asia. Recently, the picosecond laser has been introduced for various pigmentary disorders such as melasma. We evaluated the efficacy and safety of a picosecond laser with dual-wavelengths (1 064 and 595 nm) and topical 2% hydroquinone (HQ) combination therapy on patients with melasma, and compared results with those obtained with 2% HQ alone...

PURPOSE: Photodynamic therapy (PDT) is a promising treatment modality to be added in the management of glioblastoma multiforme (GBM). Light distribution modeling is required for planning and optimizing PDT. Several models have been developed to predict the light propagation inside biological tissues. In the present study, two analytical methods of light propagation emitted from a cylindrical fiber source were evaluated: a discrete and a continuous method. METHODS: The two analytical approaches were compared according to their fluence rate results...

Mesenteric cystic lymphangioma (MCL) is an uncommon, benign, slow-growing abdominal tumor that is derived from the lymphatic vessels (World J Gastroenterol. 2012;18:6328-6332, Radiographics. 1994;14:729-737). It is most often diagnosed in the head and neck of affected children. Rarely, a lymphangioma can develop within the small bowel (Pan Afr Med J. 2012;12:7). The clinical presentation of patients with an abdominal MCL can range from asymptomatic to acute abdominal pain (J Korean Surg Soc. 2012;83:102-106)...

BACKGROUND AND OBJECTIVES: Laser treatment in the early phases of wound healing may reduce scar formation. However, little is known on when in the early wound healing phases laser exposure most optimally should be provided and at which fluence levels. This study investigates the clinical effect of non-ablative-fractional-laser (NAFL) performed at three early time points at a range of fluence levels versus untreated control scars. MATERIALS AND METHODS: A randomized, controlled, intra-individual trial with erbium-glass 1,540 nm NAFL versus no laser treatment on sixteen subjects receiving 10 standardized full-thickness punch-biopsy wounds...

In recent years, mass-casualty incidents (MCIs) have become more frequent and deadly, while emergency department (ED) crowding has grown steadily worse and widespread. The ability of hospitals to implement an effective mass-casualty surge plan, immediately and expertly, has therefore never been more important. Yet, mass-casualty exercises tend to be highly choreographed, pre-scheduled events that provide limited insight into hospitals' true capacity to respond to a no-notice event under real-world conditions...

BACKGROUND AND OBJECTIVE: The use of pulsed dye laser (PDL) and fractional CO2 (FX CO2 ) laser therapy to treat and/or prevent scarring following burn injury is becoming more widespread with a number of studies reporting reduction in scar erythema and pruritus following treatment with lasers. While the majority of studies report positive outcomes following PDL or FX CO2 therapy, a number of studies have reported no benefit or worsening of the scar following treatment. The objective of this study was to directly compare the efficacy of PDL, FX CO2 , and PDL + FX CO2 laser therapy in reducing scarring post burn injury and autografting in a standardized animal model...

BACKGROUND AND OBJECTIVE: The clinical application of laser-assisted vascular anastomosis is afflicted by unreliable and low bonding strengths as well as tedious handling during microvascular surgery. The challenge to be met arises from the flow-off of the chromophore during soldering that changes the absorption and stains the surrounding tissue, leading to an uncontrollable thermal damage zone. In this study, we investigated the feasibility to produce an indocyanine green (ICG)-loaded patch by electrospinning and tested its applicability to both in vitro and in vivo microvascular laser soldering...
