Long-term follow up of intracorneal ring segment implantation in 932 keratoconus eyes.

Purpose: To evaluate the progression of keratoconus in 932 eyes of 659 patients through visual, refractive and topographic data after intracorneal ring segment (ICRS) implantation.

Methods: Retrospective review of 659 patients who underwent ICRS (Intacs®) implantation for keratoconus between September 1997 and November 2017. Demographics, preoperative and postoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA) in LogMAR, corneal topography parameters (thinnest pachymetry, Kmax), central corneal pachymetry and total follow-up time were evaluated.

Allogenic corneal tissue transplantation in substitution for extruded intracorneal rings: A case series.

We describe a case series of four eyes of four keratoconus patients with extruded intracorneal ring segments (ICRS) in whom donor corneal tissue was used to substitute for the extruded ICRS in an attempt to preserve its effect. In all patients, the extruded intracorneal ring was removed through the exposed area. Donor corneal tissue (tailored to the size and shape of the ICRS) was inserted into the empty ICRS tunnel and fixed in place using 10-0 nylon sutures.

Effects of femtosecond and excimer lasers on implanted KAMRA corneal inlay in animal models.

Purpose: To evaluate the effect of femtosecond laser and excimer laser on an intracorneal inlay (KAMRA) implanted in animal models.

Methods: Femtosecond laser was used to create corneal intrastromal pockets at 250μm depth in five porcine eyes. Four intact KAMRA inlays, examined by slit-lamp biomicroscopy and light microscopy, were implanted in the pocket of four eyes.

A 27-year experience with infective endocarditis in Lebanon.

Although rare, infective endocarditis (IE) continues to cause significant morbidity and mortality. Previous data from the American University of Beirut Medical Center (AUBMC) had shown predominance of streptococcal infection. As worldwide studies in developed countries show increasing trends in Staphylococcus aureus endocarditis, it becomes vital to continually inspect local data for epidemiological variations.

UVA-Irradiation Induces Melanoma Invasion via the Enhanced Warburg Effect.

Melanoma is a malignant tumor in which UVA (320-400 nm) radiation is considered to be an important risk factor. But the role of UVA in melanoma progression toward an invasive phenotype is still not adequately investigated. For most proliferating tumor cells the preference of aerobic glycolysis has been described as the Warburg effect.

Asymptomatic haptic migration of phakic anterior chamber intraocular lens through the peripheral iridectomy.

Objective: Case series of haptic migration in patients with angle-supported phakic anterior chamber intraocular lens (PAC-IOL: Phakic6H) through the superior peripheral iridectomy (PI).

Methods: Charts of 23 patients (35 eyes) with at least 6 months' postoperative follow-up were retrospectively reviewed. Evaluation included preoperative and postoperative cycloplegic and manifest refractions, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), slit-lamp examination, fundoscopy, corneal topography, and biometry.

A Patient with Keratoconus, Nanophthalmos, Lipodermoids, and Pigmentary Retinopathy.

A 44-year-old male with no pertinent history other than poor vision for more than 25 years was examined. Best corrected visual acuity was 20/80 OD [MR: +14.25 +1.

Complete Visual Rehabilitation in a Patient with No Light Perception after Surgical Management of a Penetrating Open-Globe Injury: A Case Report.

Open-globe injuries with no light perception (NLP) carry a poor prognosis, and many ophthalmologists select a primary enucleation or evisceration as a result. We present a case of complete visual rehabilitation in a patient who presented with NLP after a zone III penetrating open-globe injury. We recommend patient counseling regarding decision making and management of ocular trauma with NLP, since timely intervention and close follow-ups may restore useful or complete vision even in severely traumatized eyes.

Epidemiology, clinical manifestations, and molecular typing of salmonella typhi isolated from patients with typhoid fever in Lebanon.

The objective of this study was to examine the epidemiology and the clinical manifestations of typhoid fever as well as the susceptibility and strain relatedness of Salmonella typhi isolates in Lebanon from 2006 to 2007. A total of 120 patients with typhoid fever were initially identified from various areas of the country based on positive culture results for S. typhi from blood, urine, stools, bone marrow and/or positive serology.

Recurrent refractory Clostridium difficile colitis treated successfully with rifaximin and tigecycline: a case report and review of the literature.

Clostridium difficile colitis infection is on the rise and is considerably increasing the duration of hospital stay, as well as healthcare costs. The management of C. difficile colitis has become more challenging with the increasing failure of therapeutic response to metronidazole and oral vancomycin.

Transfusion-related Plasmodium ovale malaria complicated by acute respiratory distress syndrome (ARDS) in a non-endemic country.

46year old female presented with a one week history of high grade fever, chills, cough, and severe nausea. The patient had been admitted a month earlier with severe lower gastrointestinal bleeding from hemorrhoids necessitating transfusion of 7 units of packed red blood cells. Initial work-up was unremarkable.

Emergence of fluoroquinolone-resistant Streptococcus pneumoniae in Lebanon: a report of three cases.

The global emergence of Streptococcus pneumoniae resistance to fluoroquinolones is alarming and has grown to be a cause for significant concern worldwide. We report the first three cases of levofloxacin resistant S. pneumoniae isolates in a tertiary medical center in Beirut, Lebanon.

Typhoid ulcer causing life-threatening bleeding from Dieulafoy's lesion of the ileum in a seven-year-old child: a case report.

Introduction: We describe a case of rare complication of typhoid fever in a seven-year-old child and review the literature with regard to other rare causes of bleeding per rectum. Dieulafoy's lesion is an uncommon but important cause of recurrent gastrointestinal bleeding. Dieulafoy's lesion located extragastrically is rare.
