Macular hole Delphi consensus statement (MHOST).

Purpose: To derive a Delphi method-based consensus for the surgical management of Full Thickness Macular Hole (FTMH) and Lamellar Macular Hole (LMH).

Methods: 37 expert VR surgeons from 21 mainly European countries participated in Delphi method-based questionnaire for diagnosis and treatment of FTMHs and LMHs.

Results: A total of 36 items were rated in round 1 by 37 participants, of which 10 items achieved consensus: intraoperative verification of PVD; clinical superiority of OCT-based FTMH classification; practical ineffectiveness of ocriplasmin; circular 360° ILM peeling for small macular holes; use of regular surgical technique for the size of the hole in concomitant retinal detachment; performing complete vitrectomy; SF6 gas as preferred tamponade; cataract surgery if crystalline lens is mildly/moderately opaque; removal of both ILM and LHEP in LMH surgery.

Comparison of Retinal Nerve Fiber Layer and Ganglion Cell-Inner Plexiform Layer Thickness Values Using Spectral-Domain and Swept-Source OCT.

Purpose: To compare peripapillary retinal nerve fiber layer (pRNFL) and macular ganglion cell-inner plexiform layer (mGCIPL) thickness measurements obtained with spectral domain optical coherence tomography (SD-OCT) and swept-source OCT (SS-OCT) using an OCT-angiography scanning protocol, and their ability to distinguish among patients with glaucoma, glaucoma suspects (GS), and healthy controls (HC).

Methods: Cross-sectional study of 196 eyes (81 glaucoma, 48 GS, and 67 HC) of 119 participants. Participants underwent peripapillary and macular OCT with SD-OCT and SS-OCT.

Combining Structural and Vascular Parameters to Discriminate Among Glaucoma Patients, Glaucoma Suspects, and Healthy Subjects.

Purpose: Compare the ability of peripapillary and macular structural parameters, vascular parameters, and their integration to discriminate among glaucoma, suspected glaucoma (GS), and healthy controls (HCs).

Methods: In this study, 196 eyes of 119 patients with glaucoma (n = 81), patients with GS (n = 48), and HCs (n = 67) underwent optical coherence tomography (OCT) and OCT angiography to measure peripapillary retinal nerve fiber layer (pRNFL), macular ganglion cell-inner plexiform layer (mGCIPL) thicknesses, radial peripapillary capillary perfusion density (RPC-PD), and macular GCIPL perfusion density (GCIPL-PD). Parameters were integrated regionally with logistic regression and globally with machine learning algorithms.

Macular capillary displacement in exudative and tractional macular oedema: a multimodal imaging study and pathophysiological hypothesis.

Purpose: This study aims to describe vessel density differences in tractional versus exudative macular oedema with the aid of novel custom imaging analysis techniques.

Methods: In this retrospective study, patients with exudative and tractional macular oedema were imaged with optical coherence tomography (OCT), en-face OCT, OCT-angiography and fluorescein angiography. A novel image processing algorithm was developed to extrapolate data from the vessel density maps.

Optical Coherence Tomography Angiography in Neurodegenerative Disorders.

Retinal microcirculation shares similar features with cerebral small blood vessels. Thus, the retina may be considered an accessible 'window' to detect the microvascular damage occurring in the setting of neurodegenerative disorders. Optical coherence tomography angiography (OCT-A) is a non-invasive imaging modality providing depth resolved images of blood flow in the retina, choroid, and optic nerve.

Choroidal Vascularity Index: An In-Depth Analysis of This Novel Optical Coherence Tomography Parameter.

Remarkable improvements in optical coherence tomography (OCT) technology have resulted in highly sophisticated, noninvasive machines allowing detailed and advanced morphological evaluation of all retinal and choroidal layers. Postproduction semiautomated imaging analysis with dedicated public-domain software allows precise quantitative analysis of binarized OCT images. In this regard, the choroidal vascularity index (CVI) is emerging as a new imaging tool for the measurement and analysis of the choroidal vascular system by quantifying both luminal and stromal choroidal components.

Distinctive Mechanisms and Patterns of Exudative Versus Tractional Intraretinal Cystoid Spaces as Seen With Multimodal Imaging.

Purpose: To determine clear-cut distinctions between tractional and exudative intraretinal cystoid spaces subtypes.

Design: Retrospective, multicenter, observational case series.

Methods: A cohort of patients diagnosed with intraretinal cystoid spaces and imaged with optical coherence tomography (OCT), fluorescein angiography (FA), blue fundus autofluorescence (BFAF), en face OCT, and OCT angiography (OCT-A) was included in the study.

Comparing optical coherence tomography findings in different aetiologies of infectious necrotising retinitis.

Aims: To compare optical coherence tomography (OCT) features of active necrotising infectious retinitis (NIR) due to toxoplasmosis or herpesviruses and to determine distinctive OCT signs for these two causes of infectious retinitis.

Methods: OCT scans from eyes with active NIR due to varicella zoster virus (VZV), herpes simplex virus (HSV), cytomegalovirus (CMV), and toxoplasmosis (TOXO) were reviewed. All images were evaluated for the presence of previously described OCT findings in TOXO-NIR and compared with the viral group.

Numerical Magnitude Representation in Children With Mathematical Difficulties With or Without Reading Difficulties.

This study aimed to explore the spatial numerical association of response codes (SNARC), the flanker, and the numerical distance effects in children with mathematical difficulties. From a sample of 720 third, fourth, and fifth graders, 60 children were selected and divided into the following three groups: typically developing children (TD; n = 29), children with mathematical difficulties only (MD only; n = 21), and children with mathematical and reading difficulties (MD+RD; n = 10). Children were tested with a numerical Eriksen task that was built to assess SNARC, numerical distance, and flanker (first and second order congruency) effects.

Risk/benefit profile of bevacizumab in metastatic colon cancer: a systematic review and meta-analysis.

Background: Bevacizumab, an anti vascular endothelial growth factor antibody is licensed in several tumours and widely used in colorectal cancer. However, bevacizumab has several adverse effects which may appear unexpectedly and differ according to the tumour.

Aims: The aim of this work is to quantify the overall risk of bevacizumab-related side effects in patients affected by advanced colorectal cancer and to compare them with its overall benefit.

Biological and clinical features in predicting efficacy of epidermal growth factor receptor tyrosine kinase inhibitors: a systematic review and meta-analysis.

Background: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), developed for patients with advanced non-small cell lung cancer (NSCLC), give modest results similar to those with chemotherapy. There is evidence of a greater survival benefit from TKIs in patients with certain molecular and clinical features, but results are conflicting. To assess the role of these factors in predicting TKI efficacy, a pooled analysis was performed on data from randomized trials in NSCLC.

Long-term toxicity in adjuvant treatment with tamoxifen.

Long-term treatment with tamoxifen has produced few side effects, which are generally mild. Of the serious ones, all of them except eye toxicity seem to be related to the molecule's intrinsic mildly estrogen-like action, such as, for example, endometrial carcinoma. This property is also responsible for some favorable clinical effects including a lower risk of osteoporosis and cardiovascular disease.

Laparoscopic re-operation from gastro-oesophageal reflux.

Since 1994 until the present day, we have had to surgically re-operate in five cases of failure with laparoscopic operations aimed at correcting gastro-oesophageal reflux disease. Two of these cases came from our own patients and three came under our observation from other centers. We applied fundoplication according to Nissen-Rossetti in three cases and the Rossetti-Hell operation in the other cases.
