Purpose To report the effects of a single intravitreous injection of bevacizumab for the treatment of secondary choroideal neovascularisation due to large optic disc drusen. Methods A 14-year-old female patient with painless loss of vision in one eye presented with unusually large optic disc drusen and juxtapapillary choroidal neovascularisation with subretinal hemorrhage. She was treated with a single intravitreous injection of bevacizumab. Results Visual acuity increased from 20/100 to 20/25 within 4 weeks after injection and remained at this level during the 12-month follow-up period. Conclusions Bevacizumab is a possible primary treatment option for secondary choroidal neovascularisation due to large optic disc drusen in children as an alternative to other more invasive or complex procedures.Wooden foreign bodies penetrating through the orbit into paranasal sinuses are rare. We report a case of a young male who complained of double vision, pain and redness after a fall from a tree. There was no external wound over periocular skin. The clinical and radiological examination was suggestive of an inferior orbito-sinal wooden foreign body with floor fracture, which was managed by surgical removal of the foreign body and orbital floor fracture repair using a silicon sheet in a single sitting.Purpose To present a 65-year-old patient with macular hole (MH) and submacular hemorrhage (SMH) secondary to a ruptured retinal arterial macroaneurysm (RAM) which was successfully treated with a novel surgical technique. Patient A 65-year-old woman presented with a 1-week history of sudden-onset visual loss in her right eye. Her best-corrected visual acuity (BCVA) was hand motion in the right eye. Her fundus examination revealed intraretinal and massive subretinal hemorrhage with macular involvement. An MH with an approximate diameter of 600 microns was also noted. The patient was treated by a standard pars plana vitrectomy (PPV) and internal limiting membrane (ILM) peeling, followed by 10 µg recombinant tissue plasminogen activator injection into the submacular space via the MH with a 25-gauge vitrectomy probe. BCVA of the patient increased to 20/320 and 20/60, one and four weeks after surgery, respectively. Optical coherence tomography (OCT) images confirmed the complete anatomical closure of the MH and the restoration of the outer retinal layers such as the external limiting membrane and the ellipsoid zone. Conclusion This case report expands our knowledge about the management of MH in combination with SMH after a ruptured RAM. We suggest the use of a vitrectomy probe and MH for subretinal recombinant tissue plasminogen activator (rtPA) injection.Objective To emphasize the importance of an early diagnosis and an adequate treatment in conjunctival tumors. Methods We present two clinical cases and compare the course of each case one of conjunctival intraepithelial neoplasia (CIN) which took a positive course, and a fatal case of squamous cell carcinoma (SCC) with intraocular and orbital extension. Results Epithelial conjunctival malignancies are one of the most prevalent ocular surface tumors. Among these, CIN are the most common. CIN have an excellent prognosis, given adequate treatment. However, when the diagnosis of CIN is late, the epithelial basement membrane will be affected, resulting in SCC. SCC may have poorer results due to its capacity to infiltrate near tissues and create distant metastasis. Conclusion It is not common today to treat patients with orbital extension of SCC; however, it is crucial to note the importance of an early diagnosis of conjunctival malignancies. An early diagnosis is essential to prevent the transformation to other life-threatening types.The activity of pharmacologically active compounds can be increased by presenting a drug in a defined conformation, which fits exactly into the binding pocket of its target. Herein, the piperazine scaffold was conformationally restricted by substituted C2- or C3-bridges across the 2- and 6-position. https://www.selleckchem.com/products/sm-102.html At first, a three-step, one-pot procedure was developed to obtain reproducibly piperazine-2,6-diones with various substituents at the N-atoms in high yields. Three strategies for bridging of piperazine-2,6-diones were pursued 1. The bicyclic mixed ketals 8-benzyl-6-ethoxy-3-(4-methoxybenzyl)-6-(trimethylsilyloxy)-3,8-diazabicyclo[3.2.1]octane-2,4-diones were prepared by Dieckmann analogous cyclization of 2-(3,5-dioxopiperazin-2-yl)acetates. 2. Stepwise allylation, hydroboration and oxidation of piperazine-2,6-diones led to 3-(3,5-dioxopiperazin-2-yl)propionaldehydes. Whereas reaction of such an aldehyde with base provided the bicyclic alcohol 9-benzyl-6-hydroxy-3-(4-methoxybenzyl)-3,9-diazabicyclo[3.3.1]nonane-2,4-dione in only 10 % yield, the corresponding sulfinylimines reacted with base to give N-(2,4-dioxo-3,9-diazabicyclo[3.3.1]nonan-6-yl)-2-methylpropane-2-sulfinamides in >66 % yield. 3. Transformation of a piperazine-2,6-dione with 1,4-dibromobut-2-ene and 3-halo-2-halomethylprop-1-enes provided 3,8-diazabicyclo[3.2.1]octane-2,4-dione and 3,9-diazabicyclo[3.3.1]nonane-2,4-dione with a vinyl group at the C2- or a methylene group at the C3-bridge, respectively. Since bridging via sulfinylimines and the one-pot bridging with 3-bromo-2-bromomethylprop-1-ene gave promising yields, these strategies will be exploited for the synthesis of novel receptor ligands bearing various substituents in a defined orientation at the carbon bridge.[This corrects the article DOI 10.7759/cureus.9195.].Post-traumatic bronchobiliary fistulas (BBF) are extremely rare with high morbidity and mortality rates. Accurate and timely diagnosis of these entities is critical for appropriate treatment, which usually requires a multidisciplinary approach. We describe two post-traumatic cases using a multimodality approach including computed tomography (CT), magnetic resonance imaging (MRI)/Magnetic Resonance Cholangiopancreatography (MRCP), and hepatobiliary scintigraphy with specific emphasis on the imaging features for each modality. Management of hepatobiliary fistulas is complex, involving extensive diagnostic work up followed by a conservative and/or surgical approach.
