Extraocular muscle lipoma is a rare benign mesenchymal tumor of the orbit. We report a case of a 37-year-old woman who presented with chronic progressive proptosis and inferior globe displacement of left eye. External eye examination revealed a yellowish mass at the superior bulbar conjunctiva.

Article Synopsis
  • * Out of 12 patients analyzed, only 25% had detectable donor cells after a mean follow-up of 55.3 months, with all successful cases occurring in those who underwent allo-SLET.
  • * The findings suggest that while donor cells can survive long-term, their presence is not the sole factor in graft success, as the recipient's own cells seem to play a crucial role in repopulation, especially in partial cases of limbal stem cell deficiency.

Purpose: Retinoblastoma (RB) is a malignant childhood intraocular tumor. Current treatment options for RB have undesirable side effects. A comprehensive understanding of gene expression in human RB is essential for the development of safe and effective new therapies.

The entire H5N1 highly pathogenic avian influenza viral genomes were identified in the frozen autopsy specimens: the trachea, lung, colon, and intestinal feces from a patient who died of the disease in 2006. Phylogenetic analysis of the viral genomes showed that these viruses belonged to clade 1 and were the reassortants generated from the reassortment of the viruses within the same clade. The sequencing data from the autopsy specimens revealed at least 8 quasispecies of the H5N1 viruses across all 4 specimen types.

Background: Retinitis pigmentosa (RP) is a progressive inherited retinal disease with great interest for finding effective treatment modalities. Stem cell-based therapy is one of the promising candidates. We aimed to investigate the safety, feasibility, and short-term efficacy of intravitreal injection of bone marrow-derived mesenchymal stem cells (BM-MSCs) in participants with advanced stage RP.

A novel disialoganglioside 2 (GD2)-specific chimeric antigen receptor (CAR)-modified T cell therapy against retinoblastoma (RB) were generated. GD2-CAR consists of a single-chain variable fragment (scFv) derived from a monoclonal antibody, hu3F8, that is linked with the cytoplasmic signaling domains of CD28, 41BB, a CD3ζ, and an inducible caspase 9 death fusion partner. GD2 antigen is highly expressed in Y79RB cell line and in several surgical RB tumor specimens.

Purpose: To analyze the phenotype of the corneal epithelium in patients with long-term follow-up who underwent autologous cultivated oral mucosal epithelial transplantation (COMET) using in vivo confocal microscopy (IVCM) and impression cytology with immunofluorescence staining (ICIF).

Methods: Thirteen eyes from patients with severe limbal stem cell deficiency, who underwent COMET at least 48 months before, were recruited in this noncomparative cohort study. After eye examination, IVCM and ICIF were performed.

Orbital mucormycosis caused by is extremely rare. Herein, we report an immunocompetent 22-year-old Thai female who presented with two months of progressive right upper eyelid mass, associated with swelling, redness, and ptosis. She failed to improve despite multiple courses of antibiotic and steroid treatment.

Background: To report an unusual case of non-nanophthalmic uveal effusion syndrome (UES) with histologically normal sclera but responsive to scleral resection.

Case Presentation: A73-year-old man presented with a bullous retinal detachment without ciliochoroidal detachment on funduscopic examination of the right eye. The axial length of both eyes was normal.

In this study, we compared the characteristics of two strains of Zika virus (ZIKV) isolated in Thailand, one isolated from a febrile patient and one isolated from tissues of a fetus medically terminated due to congenital Zika syndrome (CZS). Replication profiles showed that the isolate from the fetal tissues replicated significantly more slowly than the fever-associated isolate in human lung A549 cells during the first 24 hours postinfection but showed a similar growth profile over longer-term infection. A much smaller difference was observed in Aedes albopictus C6/36 cells.

Article Synopsis
  • Simple limbal epithelial transplantation (SLET) and cultivated limbal epithelial transplantation (CLET) are effective methods for treating limbal stem cell deficiency (LSCD), but the best sites for tissue collection have not been clearly defined.
  • This study investigated the growth potential and stem cell marker expression from limbal explants taken from three different sites: Lcor, Lm, and Lconj, finding that the Lm and Lconj sites had better growth potential than Lcor.
  • Results indicated that cells from Lm and Lconj had higher levels of the stem cell marker ΔNp63 and a greater concentration of stem cells, suggesting these areas should be prioritized for tissue harvesting to improve outcomes for LSCD treatments.

The complete genomic sequences of H5N1 highly pathogenic avian influenza (HPAI) viruses were directly obtained from lung, trachea, and colon tissues and an intestinal fecal sample of a patient by using the next-generation sequencing technique. This is the first report on complete H5N1 viral genomes from human autopsy specimens.

Background: We report a rare presentation of extrapulmonary tuberculosis.

Case Presentation: A 29-year-old Burmese woman with human immunodeficiency virus infection and known pulmonary tuberculosis who had been treated for 5 months presented to our hospital with unilateral progressive painful visual loss of 1 month's duration. She was diagnosed with tuberculous panophthalmitis with subretinal and intraorbital abscesses, conjunctival abscess, and extraocular muscle tuberculoma.

The present study aimed to investigate the clinical outcomes of autologous cultivated oral mucosal epithelial transplantation (COMET) on human amniotic membrane (AM) for corneal limbal stem cell deficiency (LSCD). In this prospective, noncomparative case series, 20 eyes (18 patients) with bilateral severe ocular surface disease were chosen to undergo COMET on human AM. The primary outcome was clinical success, and the secondary outcomes were the best-corrected visual acuity difference, corneal opacification, symblepharon formation, and complications.

Background: Transportation into the host cell nucleus is crucial for replication and transcription of influenza virus. The classical nuclear import is regulated by specific cellular factor, importin-α. Seven isoforms of importin-α have been identified in human.

Importance: The molecular-genetic alterations contributing to the pathogenesis of sebaceous carcinoma and sebaceous adenoma remain poorly understood. Given that sebaceous carcinoma is associated with substantial morbidity and mortality, there is a critical need to delineate the pathways driving sebaceous carcinoma and candidate molecules for targeted therapy.

Objective: To describe differentially expressed microRNAs (miRNAs) in a series of periocular sebaceous carcinomas compared with sebaceous adenomas in order to identify pathways driving the pathogenesis of sebaceous carcinoma.

N-linked glycosylation of the influenza virus hemagglutinin (HA) protein plays crucial roles in HA structure and function, evasion of neutralizing antibodies, and susceptibility to innate soluble antiviral factors. The N-linked glycosylation site at position 158 of highly pathogenic H5N1 virus was previously shown to affect viral receptor-binding preference. H5N1 viruses show heterogeneity with respect to the presence of this glycosylation site.

Diagnosis of Pythium keratitis is problematic due to the difficulty in obtaining a culture report resulting in unnecessarily prolonged usage of antimicrobial medication due to misdiagnosis. This study evaluated and compared nested PCR technique with culture and immunoperoxidase staining assays of Pythium insidiosum in paraffin-embedded corneal tissues from patients with suspected fungal keratitis. Six of 51 pathological reports compatible with fungal infection and 6 of 48 culture-proven fungal keratitis were identified as Pythium.

Signet-ring cell/histiocytoid carcinomas of the eyelid are rare, slow-growing, and locally aggressive tumors. They predominantly affect elderly men and clinically resemble chronic inflammatory process such as blepharitis and chalazion. To date, the histogenesis of the tumors is still controversial.
