BACKGROUND: Many gynecologic, urologic and pelvic reconstructive surgeries require accurate intra-operative evaluation of ureteral patency. OBJECTIVE: We performed a randomized controlled trial to compare surgeon satisfaction with four methods of evaluating ureteral patency during cystoscopy at the time of benign gynecologic or pelvic reconstructive surgery: oral phenazopyridine, intravenous sodium fluorescein, mannitol bladder distention and normal saline bladder distention...

Positioned at the intersection of the head, body and forelimb, the pectoral girdle has the potential to function in both feeding and locomotor behaviours-although the latter has been studied far more. In ray-finned fishes, the pectoral girdle attaches directly to the skull and is retracted during suction feeding, enabling the ventral body muscles to power rapid mouth expansion. However, in sharks, the pectoral girdle is displaced caudally and entirely separate from the skull (as in tetrapods), raising the question of whether it is mobile during suction feeding and contributing to suction expansion...

Zhiying Ji, Matthew J LeBaron
The Pig-a assay, a recently developed in vivo somatic gene mutation assay, is based on the identification of mutant erythrocytes that have an altered repertoire of glycosylphosphatidylinositol (GPI)-anchored cell surface markers. We hypothesized that the erythrocyte Pig-a assay concept could be applied to rat cauda epididymal spermatozoa (sperm) for germ cell mutagenicity evaluation. We used GPI-anchored CD59 as the Pig-a mutation marker and examined the frequency of CD59-negative sperm using flow cytometry...

Miltogramminae is one of the phylogenetically most poorly studied taxa of the species-rich family Sarcophagidae (Diptera). Most species are kleptoparasites in nests of solitary aculeate wasps and bees, although parasitoids and saprophagous species are also known, and the ancestral miltogrammine life habit remains unsettled. Here, we present for the first time a comprehensive phylogenetic tree consisting of 58 representatives of Miltogramminae, reconstructed using sequence data from three mitochondrial (COI, cytB, ND4) and one nuclear (Ef-1α) genes...

REVIEW
Sean P Edwards
Microvascular reconstruction of ablative defects has become a mainstay of contemporary management of head and neck cancer patients. These techniques offer myriad tissue options that vary in character, volume, and components and have vastly improved the esthetic and functional outcomes achieved in this patient population. Although consensus exists regarding the reliability and functional and esthetic benefits of free tissue transfer, the same cannot be said for oncologic outcomes. The increase in resources required for the routine use of free tissue transfer has led to asking this question-Do vascularized free flaps allow for increased surgical margins and improvements in oncologic outcomes?...

REVIEW
Amin Rahpeyma, Saeedeh Khajehahmadi
BACKGROUND: There are different flaps based on the branches of the maxillary artery. Flaps based on the maxillary artery branches can be used for oral cavity reconstruction in selected cases, but there is lack of comprehensive review in this topic. METHODS: A literature review was performed on Medline for maxillary artery based flaps and oral cavity reconstruction. Surgical techniques for each possible variant of maxillary artery based flaps and an example of each situation for oral cavity reconstruction is explained...

Eyelid reconstruction, though challenging, can produce a functional, esthetically pleasing lid. This should preferably be accomplished with a one-stage procedure, using robust, well-vascularized tissues similar to those being replaced, with minimal associated donor morbidity. According to the experience with Bichat pedicled flap in oral reconstruction, the authors propose the use of pedicle infraorbital fat pad for repair of conjunctival defect. Seven patients underwent eyelid reconstruction of full-thickness oncological or post-traumatic defects...

This article describes our surgical technique for subperiosteal midface elevation in patients with paralytic lower eyelid malposition or cicatricial inferior eyelid retraction. Nineteen patients with paralytic lower eyelid malposition and 15 patients with cicatricial inferior eyelid retraction underwent a subperiosteal midface lift (n = 34). The procedure was performed under local anesthesia through three nonvisible incisions. A transconjunctival incision allows preseptal dissection to the orbital rim, followed by a subperiosteal dissection of the midface...

BACKGROUND: Computer-guided 3D virtual planning and customized templates are novel and effective methods aiding maxillary reconstruction, particularly during osteocutaneous free tissue transfer of complex defects. However, virtual planning and modelling is often expensive. METHODS: We present a new method to reconstruct complex defects with a surgical stent designed from presurgical casts. We present 2 patients who underwent this technique. Reconstruction in both cases was aided by a surgical stent fashioned preoperatively to approximate the anatomic dimensions of the defect, guiding the shape and orientation of the flap during inset to aid in dental rehabilitation...

The oral and maxillofacial region is rich in blood, and it is often difficult to stop bleeding during the operation of maxilla. Nitroglycerin is one of the most commonly used antihypertensive drugs in our hospital. We observed the effect of controlled hypotension in patients with maxillary resection. In group N, the patients had different degrees of tachycardia after using nitroglycerin only. In addition, nitroglycerin has the characteristics of rapid drug resistance. A combined reversed temporal muscle flap and random forehead flap technique was performed successfully to reconstruct the large defect after ipsilateral maxillectomy and orbit evisceration...

Adipose tissue-derived stem cells (ASCs) are known to be tissue-healing promoters due to their cellular plasticity and secretion of paracrine factors. Cultured ASC sheets provide a novel method of ASCs application and can retain ASCs at the targeted tissue. The purpose of this systematic review is to evaluate preclinical studies using adipose tissue-derived cell (ASC) sheet transplantation therapy for promoting tissue healing. Firstly, we searched databases to identify studies of ASC sheet therapy in different experimental animal models, and then determined the quality score of studies using SYRCLE's risk bias tool...
