Metastatic cystic lesions may be considered as target lesions according to the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. However, cystic lesions are considered as non-measurable according to RECIST 1.0. Krukenberg tumors are cystic metastases from gastric cancer. The aim of the present case report was to address the question of whether a Krukenberg tumor can be considered as a target lesion. A 30-year-old female patient was diagnosed with stage IV gastric cancer 6 months after parturition. Subsequently, the patient received two courses of oxaliplatin/capecitabine plus trastuzumab (OCT) treatment...

BACKGROUND: Changes in retinal fluid patterns associated with circumscribed choroidal hemangioma (CCH) have not been investigated yet. A long-term follow-up study was performed to evaluate the changes of retinal fluid patterns and treatment responses. METHODS: We retrospectively reviewed medical records of all CCH patients diagnosed between November 2005 and March 2017. Enrolled patients had visual symptoms, were treatment-naïve, and had been followed-up for more than 2 years...

Purpose: Intrinsically photosensitive retinal ganglion cells (ipRGCs) contain the photopigment melanopsin, and are primarily involved in non-image forming functions, such as the pupillary light reflex and circadian rhythm entrainment. The goal of this study was to develop and validate a targeted ipRGC immunotoxin to ultimately examine the role of ipRGCs in macaque monkeys. Methods: An immunotoxin for the macaque melanopsin gene ( OPN4 ), consisting of a saporin-conjugated antibody directed at the N-terminus, was prepared in solutions of 0...

Nerve Fiber Layer (RNFL) measurements in the same altitudinal half of the eye in hyper-tension (HTG) and normal-tension glaucomas (NTG). MATERIALS AND METHODS: We examined both eyes in altogether 50 patients (100 eyes). The cohort was divided into two groups, in each of them; there were 25 patients with average age of 55.4 in the NTG group and 54.6 years in the HTG group. The NTG group consisted of 17 women of the average age of 55.35 (range, 25-75) years, and 8 men of the average age of 55...

PURPOSE: To evaluate OCT findings and long-term follow-up results in patient with optic disc pit (ODP) and associated maculopathy treated with pars plana vitrectomy (PPV). METHODS: Six eyes of 6 patients (3 females, 3 males) were included in a retrospective study. We excluded patients with ODP without maculopathy. Patients were followed in years 2008-2017. Mean age at the first examination was 40,3 years (15-70 years). Duration of worsening of the best corrected visual acuity (BCVA) ranged from 2 days to few years...

BACKGROUND: Corneal optical coherence tomography (anterior segment OCT, AS-OCT) is described in the current IC3D classification of corneal dystrophies to be a method for improvement of clinical diagnostics and treatment. OBJECTIVE: In this case series AS-OCT images of corneal dystrophies were analyzed with respect to morphological changes. MATERIAL AND METHODS: This was a retrospective imaging and morphological case series with 38 eyes. For image acquisition the corneal module of the high-resolution spectral-domain OCT Zeiss Cirrus HD-5000 platform (Oberkochen, Germany) was employed...

Objective: Big bubble (BB)-deep anterior lamellar keratoplasty (DALK) has become the reference transplantation technique for corneal stromal disorders. Type 1 BB is the desired aspect but it is not constant. We aimed to determine the predictive factors of type 1 BB success. Methods: Observational cohort study including 77 consecutive eyes of 77 patients undergoing DALK by one surgeon at a single reference center without any selection. Clinical and spectral domain optical coherence tomography data were collected pre- and postoperatively...

Background: Optical coherence tomography (OCT) is an intravascular, high-resolution imaging technique that is used to characterize atherosclerotic plaques. However, the identification of macrophages as important markers of inflammation and plaque vulnerability remains difficult. Here, we investigate whether the uptake of very small iron oxide particles (VSOP) in macrophages, that cluster in phagolysosomes and allow high-quality magnetic resonance imaging (MRI) of atherosclerotic plaques, and uptake of ferumoxytol nanoparticles enhance detection of macrophages by OCT...

BACKGROUND: We evaluated the changes in antroduodenal manometry (ADM) parameters and interpretation when the test is performed the day of catheter placement and the following day. METHODS: Catheter was placed endoscopically under anesthesia and recorded on day 1 and repeated on day 2. Study parameters including antrum and small bowel motility index (MI) during fasting, meal, postprandial, erythromycin (EES), and octreotide (OCT) challenge phases, the presence of the phase III of the migrating motor complex (MMC), visual postprandial response, and study interpretation were compared between both days...

PURPOSE: To evaluate structural changes in the choroid among patients with diabetic macular edema (DME), with varying grades of diabetic retinopathy (DR), using enhance depth imaging spectral domain optical coherence tomography (EDI SD-OCT) scans. METHODS: A cross-sectional study was conducted on 82 eyes with DR and DME and 86 healthy control eyes. Eyes with DME were classified according to the severity of DR as per the international DR severity scale. Sub foveal choroidal thickness (SFCT)was obtained using EDI SD-OCT scans...

BACKGROUND: This study investigated the association of central macular thickness (CMT) and macular volume (MV) with severity of Behçet uveitis in the absence of macular edema (ME). METHODS: This retrospective, interventional study included a total 131 treatment-naïve Behçet patients with varying degree of uveitis in the absence of ME.

PURPOSE: To evaluate the clinical efficacy of a novel screening sign (i.e., the Triple Hump [TH] sign) for prediction of laser peripheral iridotomy (LPI)'s intraocular pressure (IOP)-lowering effectiveness in subjects with asymptomatic narrow angles. METHODS: This cross-sectional study was conducted from 2010 to 2015 in a hospital setting. Eighty-four (84) eyes of 84 primary angle-closure suspect (PACS) patients were imaged before LPI using anterior-segment optical coherence tomography (AS-OCT)...

Objective: To study the effects of ultraviolet light combined with riboflavin treatment (corneal collagen-crosslinking, CXL) on infectious control and stromal reconstruction of bacterial keratitis. Methods: Experimental Study. A Staphylococcus aureus rabbit keratitis model was established by injecting Staphylococcus aureus broth into the shallow stromal layer of the right eye cornea of New Zealand white rabbits. Forty-four rabbits that successfully established the model were randomly divided into four groups: corneal collagen cross-linking (CXL) group, antibiotic group, CXL+ antibiotic group and untreated group, with 11 rabbits in each group...

BACKGROUND: Patients with retinal diseases frequently complain of poor visual function even when visual acuity is relatively unaffected. This clinical finding has been attributed to deficits in contrast sensitivity (CS). The purpose of our study was to evaluate the CS in patients with clinical and genetic diagnosis of inherited retinal degeneration (IRD) and relatively preserved visual acuity. METHODS: Seventeen patients (30 eyes) with IRD and visual acuity of 20/40 or better, and 18 controls (18 eyes) without any ocular condition underwent slit lamp examination, visual acuity testing via standard Snellen chart testing, CS testing via the Quick Contrast Sensitivity Function (QCSF), and Spectral Domain Optical Coherence Tomography (SD-OCT)...

The monoterpene isolated from Mentha haplocalyx, 3,3,5-trimethyl-2-oxabicyclo[2.2.2]oct-5-en-4-ol, was synthesized according to its proposed structure. However, the NMR data of the synthetic sample were not in agreement with those reported for the natural product. After considerable efforts, the genuine structure was confirmed as (1R*,2R*)-4-(1'-hydroxy-1'-methylethyl)-1-methylycyclohex-3-ene-1,2-diol.
