Tissue adhesives have emerged as an alternative to sutures and staples for wound closure and reconnection of injured tissues after surgery or trauma. Owing to their convenience and effectiveness, these adhesives have received growing attention particularly in minimally invasive procedures. For safe and accurate applications, tissue adhesives should be detectable via clinical imaging modalities and be highly biocompatible for intracorporeal procedures. However, few adhesives meet all these requirements. Herein, we show that biocompatible tantalum oxide/silica core/shell nanoparticles (TSNs) exhibit not only high contrast effects for real-time imaging but also strong adhesive properties...

Surgical resection of solid cerebellar hemangioblastomas can be challenging because of the profuse blood supply and tight space. We report two cases of solid cerebellar hemangioblastomas treated via surgical resection with the aid of preoperative endovascular embolization on the day of surgery. Case 1: A 36-year-old woman presented with a two-month history of headache and vomiting. Magnetic resonance imaging(MRI)revealed a right cerebellar solid mass, mild hydrocephalus, and apparent peritumoral edema. Angiogram showed a highly vascularized mass, three feeding arteries from the superior cerebellar artery(SCA), and a dilated vein draining into the confluence...

Ingredients found in the nail cosmetic industry, including but not limited to methacrylate and acrylate monomers, formaldehyde, and toluene sulfonamide-formaldehyde resin, can incite allergic contact dermatitis. An eczematous outbreak presents on areas surrounding the nail plate and may spread through contact transfer of the allergen, commonly to the face and neck. Even components that were originally deemed nonsensitizing, such as the ubiquitous cyanoacrylate adhesive family, have been found to be allergenic...

Uterine artery pseudoaneurysm is a rare but potentially life-threatening complication that can occur after various uterine manipulations. A 34-year-old nulliparous patient with a previous history of four consecutive miscarriages with unknown etiologies underwent transmyometrial oocyte retrieval as a result of malpositioning of the right ovary. Six days later, she experienced massive vaginal bleeding after a day of intermittent bleeding and was transferred to our hospital. At triage, continuous bleeding from the cervical canal was observed...

BACKGROUND AND AIMS: Gastric varices (GV) have higher rates of morbidity and mortality from hemorrhage than esophageal varices. Several studies have shown the safety and efficacy of cyanoacrylate (CA) injection for acute gastric variceal hemorrhage. We report data from our experience with CA injection for GV before and after routine use of post-injection audible Doppler assessment (ADA) for GV obturation and describe long-term outcomes after this therapy. METHODS: We retrospectively identified patients who had documented GV, underwent CA injection, and had at least 2 weeks of follow-up...

Donor--Acceptor dyes containing thiophenyl -conjugated units and cyanoacrylate acceptor groups are among the best-performing organic chromophores used in dye-sensitized solar cell (DSC) applications. Yet, the molecular origins of their high photovoltaic output have remained unclear until now. This synchrotron-based X-ray diffraction study eluci-dates these origins for the high-performance thiophenylcy-anoacrylate-based dye, MK-2 (7.7% DSC device efficiency), and its molecular building block, MK-44. The crystal struc-tures of MK-2 and MK-44 are both determined, while a high-resolution charge-density mapping of the smaller mole-cule was also possible, enabling the nature of its bonding to be detailed...

Importance: The lateral crural overlay technique is a powerful technique for altering nasal tip projection and rotation. By overlapping and thus shortening the lateral crura, the nasal tip is shortened and rotated upward, thus decreasing projection and increasing rotation. There is no data to show the association of this technique with the strength of the lower lateral cartilage. Strengthening of the lower lateral cartilages would presumably lead to resistance to external nasal valve collapse and improved airway...

INTRODUCTION: The accumulation of fluid, a seroma, is a frequent complication after modified radical mastectomy or quadrantectomy with lymph node dissection. The aim of the present study was to examine whether a new adhesive material made of cyanoacrylate can effectively provide a sealing coat to tissues and thus reduce the incidence of seroma significantly. PATIENTS AND METHODS: The present prospective, randomized case-control study included 128 women with a breast cancer diagnosis and scheduled for modified radical mastectomy or quadrantectomy with lymph node dissection in Thessaloniki, Greece...

A 54-year old male liver transplant recipient with Roux-en-Y choledochojejunostomy was admitted for symptomatic anemia. Despite endoscopies and a bleeding scan, active bleeding was not visualized. Angiography and abdominal computed tomography demonstrated possible jejunal varices at the choledochojejunal anastomosis. Double-balloon enteroscopy demonstrated varices with overlying clots in the Roux limb at the anastomosis. Due to the extensive loop formation and unstable position of the endoscope, therapeutic intervention could not be performed...

Renal injury is common in abdominal trauma. Adhesives and sealants can be used to repair and preserve damaged organs. We describe the effect of three biomaterial treatments (TachoSil, GelitaSpon, and Adhflex) on injured renal tissue. Renal traumatic injuries were experimentally induced in male Wistar rats (n = 90) using a punch. Animals were divided into five groups: (1) sham noninjured (n = 3) and punch injury groups; (2) nontreated (n = 6); (3) TachoSil (n = 27); (4) GelitaSpon (n = 27); and (5) Adhflex (n = 27)...

BACKGROUND: The standard of care for treatment of low-flow venous malformations (VMs) is percutaneous sclerotherapy. These lesions are seldom surgically resected, especially if the malformation is in an anatomically difficult location. Percutaneous sclerotherapy is safe and effective. However, the drawbacks to sclerotherapy are the need for repeated treatments and risks of skin ulceration, deep venous thrombosis, scarring/contractures, and nerve damage. Surgical resection can be difficult because of intraoperative bleeding, intraoperative lesional decompression, and difficulty in localization...

BACKGROUND: Radiosurgery is a valuable option to treat arteriovenous malformations. There are correlations between some morphological nidal features and final results, and the benefits of preradiosurgical embolization have not been well established thus far. METHODS: Analysis of a longitudinal cohort of 47 consecutive patients who underwent radiosurgery with or without previous embolization. Embolizations were performed exclusively with n-butyl cyanoacrylate. Radiosurgery was delivered either as a single or divided in up to 5 equal fractions...

BACKGROUND: Neurofibromatosis type 1 (NF1) is a rare disease with an incidence of one in every 3000 births. Numerous studies have focused on the main function of NF1 as a tumor suppressor, while few have examined the cerebrovascular abnormalities observed in patients with NF1. It is worth noting that intracranial aneurysms are uncommon in this condition. CASE DESCRIPTION: We report a case of NF1 with a dissection of the distal segment of the superior cerebellar artery...

BACKGROUND: Preoperative endovascular embolization of intracranial meningiomas denatures the tumor tissue, reduces intraoperative blood loss, and facilitates surgical removal. However, as most meningiomas are surgically removed within a few days after embolization, the effect of long-term volume reduction of the tumor due to the endovascular embolization remains unknown. METHODS: Between January 2006 and December 2014, 5 patients with intracranial meningioma underwent endovascular embolization and were followed without surgical resection for >14 days...
