Altered Intrinsic Functional Connectivity of the Primary Visual Cortex in Patients with Corneal Ulcer: A Resting-State fMRI Study.

Neuropsychiatr Dis Treat 2020 23;16:1571-1581. Epub 2020 Jun 23.

Department of Ophthalmology, The First Affiliated Hospital of Nanchang University, Jiangxi Province Clinical Ophthalmology Institute, Nanchang 330006, Jiangxi, People's Republic of China.

Purpose: To investigate differences in the functional connectivity (FC) of the primary visual cortex between patients with corneal ulcer (CU) and healthy controls (HCs) using resting-state functional magnetic resonance imaging.

Patients And Methods: A total of 30 patients with CU and 30 HCs were closely matched in terms of sex, age, and level of education. Two-sample -test, receiver operating characteristic curve, and Pearson's correlation coefficient analyses were used to determine the differences in FC between the two groups, the mean FC value of patients with CU and HCs, and the correlation between FC signal values and clinical manifestations in different brain regions of patients.

Department of Pain Clinic, The First Affiliated Hospital, Nanchang University, Nanchang, Jiangxi, 330006, People's Republic of China. Electronic address:

Objectives: To compare the advantages and disadvantages of V2 + V3 idiopathic trigeminal neuralgia using peripheral nerve radiofrequency (RF) thermocoagulation (PRF) via the foramen rotundum (FR) and foramen ovale (FO) with those of semilunar ganglion RF thermocoagulation (GRF) under local anesthesia, for exploring a new and available surgical method for patients with V2 + V3 idiopathic trigeminal neuralgia.

Patients And Methods: 102 patients with V2 + V3 idiopathic trigeminal neuralgia were enrolled in this prospective randomized controlled clinical trial, and they were divided into the PRF and GRF group randomly (n = 51 in both groups). The outcome of pain relief was assessed using the Barrow Neurological Institute (BNI) pain score, and grouped as good (BNI Class I or II, no medication required) and bad (BNI Class III-V, medication required or failed).

Fistulas healing. Stable gastric pentadecapeptide BPC 157 therapy.

Curr Pharm Des 2020 Apr 24. Epub 2020 Apr 24.

Departments of Pharmacology and Pathology, School of Medicine, University of Zagreb, Salata 11, POB 916, 10000 Zagreb. Croatia.

This review is focused on the healing of fistulas and stable gastric pentadecapeptide BPC 157. Assuming that the healing of the various wounds is essential also for the gastrointestinal fistulas healing, the healing effect on fistulas in rats, consistently noted with the stable gastric pentadecapeptide BPC 157, may raise several interesting possibilities. BPC 157 is originally an anti-ulcer agent, native to and stable in human gastric juice (for more than 24 h). Read More

Amniotic membrane transplantation for managing dry eye and neurotrophic keratitis.

Taiwan J Ophthalmol 2020 Jan-Mar;10(1):13-21. Epub 2020 Mar 4.

R&D Department, TissueTech Inc., Miami, FL, USA.

Neurotrophic keratitis (NK), a degenerative disease caused by damage to the trigeminal nerve, abolishes both tearing and blinking reflexes, thus causing the most severe forms of dry eye disease (DED). Conversely, the increasing severity of DED also leads to progressive loss of corneal nerve density, potentially resulting in NK. Both diseases manifest the same spectrum of corneal pathologies including inflammation and corneal epithelial keratitis, which can progress into vision-threatening epithelial defect and stromal ulceration.

Accelerated Corneal Cross-linking as an Adjunct Therapy in the Management of Presumed Bacterial Keratitis: A Cohort Study.

J Refract Surg 2020 Apr;36(4):258-264

Purpose: To compare the outcomes of accelerated photoactivated chromophore for keratitis corneal cross-linking (PACK-CXL) as an adjunct treatment for bacterial keratitis (PACK-CXL plus standard antibiotic therapy) for patients receiving only standard antibiotic therapy.

Methods: Retrospective cohort study of outcomes of patients with moderate infectious presumed bacterial keratitis (ulcer diameter 2 to 7 mm and stromal depth < 300 µm) were compared before and after initiation of a new treatment protocol of PACK-CXL in addition to standard antibiotic treatment.

Results: A total of 70 eyes of 70 patients were included: 39 eyes in the PACK-CXL plus antibiotic (PACK-ABX) group and 31 eyes in the antibiotic only (ABX) control group. Read More

Department of Ophthalmology, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, Kaohsiung City, Taiwan.

Background: Fungal keratitis (FK) has been shown to be a climate-sensitive disease. The differentiation between FK from bacterial keratitis (BK) was difficult. The purpose of this study was to compare the bacteriology and mycology between tropical and subtropical Taiwan and to investigate the independent risk factors for identification of fungi from bacteria.

Evaluation of molecular identification of species causing fungal keratitis.

Saudi J Biol Sci 2020 Feb 26;27(2):751-756. Epub 2019 Dec 26.

Department of Medical Laboratory Sciences, College of Applied Medical Sciences, Majmaah University, Al Majmaah 11952, Saudi Arabia.

Fungal keratitis caused by the species of is a common and leading problem in developing countries like India. In this study, a total of 135 isolates from keratitis were studied by sequence analyses of the internal transcribed spacer (ITS) region performed by nucleotide-nucleotide BLAST analysis followed by the initial identification of the isolates based on conidial and colony morphology. The sequence analysis revealed several unusual species which were never reported in eye infections such as , , , . Read More

Introduction: Mooren's ulcer is a painful, inflammatory chronic keratitis that affects corneal periphery, progressing centripetally, ultimately ending in perforation. The first line of treatment includes systemic immunomodulators, with surgery being the last option. We present a case of bilateral Boston keratoprosthesis implantation for severe Mooren's ulcer that responded differently in each eye. Read More

Ocular complications from diabetes mellitus are common. Diabetic keratopathy, the most frequent clinical condition affecting the human cornea, is a potentially sight-threatening condition caused mostly by epithelial disturbances that are of clinical and research attention because of their severity. Diabetic keratopathy exhibits several clinical manifestations, including persistent corneal epithelial erosion, superficial punctate keratopathy, delayed epithelial regeneration, and decreased corneal sensitivity, that may lead to compromised visual acuity or permanent vision loss.
