2. Lacrimal sac exposure and a superior lateral anterior pedicle flap to improve outcomes of Draf type II and III procedures. (PubMed)

Lacrimal sac exposure and a superior lateral anterior pedicle flap to improve outcomes of Draf type II and III procedures. Although the efficacy of Draf type II and III procedures for frontal sinus diseases is well recognized, a certain amount of postoperative stenosis of the frontal neo-ostium occurs. Exposed bone induces inflammation and leads to osteoneogenesis. To prevent stenosis, we developed a surgical technique designed to minimize bone exposure while maximizing the frontal neo-ostium (...) area created with Draf type II and III procedures. We fully exposed the lacrimal sac and used a superior lateral anterior pedicle flap to cover the exposed bone during the Draf procedure. We aimed to describe our technique.We reviewed 19 patients who underwent a Draf type II or III procedure with our technique. Endoscopic views from the follow-ups and complications were evaluated.Overall, the neo-ostium remained patent in all patients. No complications, such as synechiae or orbital injury, were

% of sinuses a prelacrimal endoscopic access is readily feasible, while in 56.5% temporary tear sac dislocation is required and in 31.5% lacrimal sac dislocation is always needed along with a significant amount of bone removal to enable PLWA. (...) Anterior maxillary wall and lacrimal duct relationship - CT analysis for prelacrimal access to the maxillary sinus. The distance between the anterior wall of the maxillary sinus and the nasolacrimal duct shows a large individual variation.To evaluate the feasibility of accessing the maxillary sinus through a prelacrimal window access (PLWA), a series of 100 paranasal CT scans from adult patients was analysed retrospectively.

4. Lacrimal gland uptake on F-18 florbetapir amyloid positron emission tomography scan (PubMed)

Lacrimal gland uptake on F-18 florbetapir amyloid positron emission tomography scan In 2012, the Food and Drug Administration (FDA) approved the use of F-18 florbetapir to estimate β-amyloid neuritic plaque density when indicated. A normal scan will show increased radiotracer uptake in the white matter. Mild uptake in salivary glands, skin, muscles, and bones is considered normal. Being a new and infrequently performed study, familiarity with normal biodistribution and variants is important. We (...) hereby present 2 cases with F-18 florbetapir uptake in lacrimal glands. Patients had no symptoms or known systemic conditions to explain this uptake. We speculate that lacrimal gland uptake of F-18 florbetapir could represent a normal variant.

5. A Modified Preserved Nasal and Lacrimal Flap Technique in Endoscopic Dacryocystorhinostomy (PubMed)

). No significant complications occurred intraoperatively. We concluded that the modified preserved nasal and lacrimal mucosal flap technique in EES-DCR for treating PANDO is simple and safe, can effectively cover the bare bone around the opened sac, and provide a similar or even better clinical outcome compared with other routine treatment techniques used for this condition. (...) A Modified Preserved Nasal and Lacrimal Flap Technique in Endoscopic Dacryocystorhinostomy Here we describe a modified preserved nasal and lacrimal mucosal flap technique in endonasal endoscopic dacryocystorhinostomy (EES-DCR) for patients with epiphora secondary to primary acquired nasolacrimal duct obstruction (PANDO) and evaluate its outcomes. Twenty-five patients with PANDO were retrospectively reviewed. Modified preserved nasal and lacrimal mucosal flap technique in EES-DCR was applied

6. Mesenchymal stromal cells promote B-cell lymphoma in lacrimal glands by inducing immunosuppressive microenvironment (PubMed)

in a context-dependent manner. We here investigated the effects of bone marrow-derived MSCs in a murine model of lacrimal gland B-cell lymphoma. Co-injection of MSCs with B lymphoma cells enhanced tumor growth in lacrimal glands without long-term engraftment. Of note, MSCs induced greater infiltration of immune and immune-regulatory cells near tumor: CD4+ cells, CD11b+ cells, CD4+Foxp3+ regulatory T cells and CD11b+Ly6C+Ly6G- myeloid-derived suppressor cells. Concurrently, there was up-regulation of immune (...) Mesenchymal stromal cells promote B-cell lymphoma in lacrimal glands by inducing immunosuppressive microenvironment Mesenchymal stromal cells (MSCs) have therapeutic potential for various diseases because of their anti-inflammatory and immunosuppressive properties. However, the immunosuppressive microenvironment allows tumor cells to evade immune surveillance, whereas maintenance of inflammation is required for tumor development and progression. Hence, MSCs may promote or suppress tumors

7. New TASER injuries: lacrimal canaliculus laceration and ethmoid bone fracture. (PubMed)

New TASER injuries: lacrimal canaliculus laceration and ethmoid bone fracture. The TASER is a non-lethal conducted electrical weapon intended to incapacitate a person. The growing use of the TASER has resulted in an increased risk of injuries, including those to the face. We report a case of lacrimal canaliculus laceration and ethmoid bone fracture caused by an extra penetration (XP) TASER X26 dart. A 35-year-old was subdued with a TASER head shot; the probe was discharged into the left medial (...) canthus without causing any ocular lesions. A computed tomography scan revealed the probe to be embedded in the left nasolacrimal duct and showed a displaced ethmoid fracture. The barbed dart had sectioned the inferior lacrimal canaliculus without electrifying the lesion. This case expands the knowledge of injuries that may occur as a result of the use of this device and the management of peri-ocular TASER injuries.

Solitary Fibrous Tumor in the Lacrimal Gland Fossa: A Case Report Solitary fibrous tumors (SFTs) are benign, spindle-cell tumors of mesenchymal origin that are usually seen in the superior orbital area in adults. We report a rare case of SFT in the lacrimal gland fossa that developed in a young female. A 25-year-old woman had a 6-month history of a progressive painless mass in the left upper eyelid accompanied by proptosis. Computed tomography and magnetic resonance imaging showed an ovoid

9. Unusual Pleomorphic Adenoma of the Lacrimal Gland: Immunohistochemical Demonstration of PLAG1 and HMGA2 Oncoproteins. (PubMed)

Unusual Pleomorphic Adenoma of the Lacrimal Gland: Immunohistochemical Demonstration of PLAG1 and HMGA2 Oncoproteins. Painless low-grade right proptosis with 20/25 visual acuity developed slowly in a 49-year-old woman with a past history of breast cancer. Imaging studies disclosed an oval-to-round superotemporal mass in the right lacrimal fossa without bone erosion. Excisional biopsy revealed a pseudoencapsulated, bosselated tumor with a spindled, hypocellular, and heavily periodic acid Schiff (...) product which may be aberrantly overexpressed in malignancy, was observed in rare cells. Immunohistochemical probes for HMGA2 and PLAG1 oncoproteins, characteristic of pleomorphic adenoma, were stained intensely and less intensely, respectively. MYB and c-KIT (CD117) were negative, thereby strongly arguing against the diagnosis of adenoid cystic carcinoma. In atypical epithelial tumors of the lacrimal gland, genetic probes identifying distinctive gene translocations or their oncoprotein products

Delivery of Bone Marrow-Derived Mesenchymal Stem Cells Improves Tear Production in a Mouse Model of Sjögren's Syndrome The purpose of the present study was to test the potential of mouse bone marrow-derived mesenchymal stem cells (BD-MSCs) in improving tear production in a mouse model of Sjögren's syndrome dry eye and to investigate the underlying mechanisms involved. NOD mice (n = 20) were randomized to receive i.p. injection of sterile phosphate buffered saline (PBS, control) or murine BD (...) -MSCs (1 × 106 cells). Tears production was measured at baseline and once a week after treatment using phenol red impregnated threads. Cathepsin S activity in the tears was measured at the end of treatment. After 4 weeks, animals were sacrificed and the lacrimal glands were excised and processed for histopathology, immunohistochemistry, and RNA analysis. Following BD-MSC injection, tears production increased over time when compared to both baseline and PBS injected mice. Although the number
