Atypical intraorbital dermoid and epidermoid cyst: A single institution cross-sectional retrospective study.

Purpose: Intraorbital epidermoid and dermoid cyst (DC) has been reported in the literature rarely. The current study evaluates clinicopathologic, radiologic, and management of intraorbital DC cases over ten years. Methods: In this cross-sectional study, the medical records of patients with intraorbital DC treated at the academic referral center for ocular surgery were retrospectively reviewed. Data reviewed included the patient's demographic characteristics, clinical features, imaging, surgical technique, and pathology report. Results: Nine patients with a rare presentation of intraorbital DC were reviewed within the study period in five presentations (five intraosseous, one intraconal, one dumbbell-shaped with a large part in anterior orbit, one juxta levator palpebral muscle, and one recurrent case with intracranial extension). They ranged from 8 to 53 years of age, with a median of 29 years, and five (55.6%) were female. Histopathological evaluation revealed two cysts were epidermoid. Conclusion: The current study provides more clinical and radiologic manifestations of rare presentations of DC that highlight the importance of high clinical suspicion in the approach to atypical DC.

Cherubism: report of three cases and literature review.

PURPOSE: To report 3 cases of cherubism, one of whom underwent surgery for orbital manifestations, and to provide a literature review. CASE REPORTS: Our patients were normal at birth and developed painless enlarging of the cheeks and jaws when they were 4-5 years old. Ophthalmologic examinations showed mild proptosis, superior globe displacement and inferior scleral show in all cases. Cases 2 and 3 had lower lid skin discoloration. Computed tomography (CT) scans demonstrated bilateral multicystic lesions in the maxilla and mandible with cortical thinning in all cases. In Case 3, left eye hyperglobus and anisometropic amblyopia was seen. In this case, the CT scan showed a round, well-defined and homogeneous mass, involving the anterior and superior walls of the maxillary sinus on the left side, extending into inferior orbit. Debulking of the mass was performed at the surgery. The pathologic findings were compatible with the diagnosis of giant cell reparative granuloma. He returned 1 year after surgery with recurrence of the mass. DISCUSSION: A few cases were reported in the literature with histopathologically proven orbital cherubism. To our knowledge, lower lid skin discoloration in Cases 2 and 3 and anisometropic amblyopia in case 3 were not described elsewhere in cherubism cases. We recommend that all cases with cherubism must be examined by an ophthalmologist to diagnose and treat possible orbital manifestations.

The prevalence of amblyogenic factors in children with persistent congenital nasolacrimal duct obstruction.

BACKGROUND: To evaluate the prevalence of amblyopia risk factors in children that underwent probing for persistent congenital nasolacrimal duct obstruction (CNLDO). METHODS: The medical records of children with CNLDO (after 1 year of age) that underwent probing were reviewed. Amblyopia risk factors, based on the American Association for Pediatric Ophthalmology and Strabismus referral criteria in 2013, were sought in the patientsʹ records before probing. The proportion of the patients with anisometropia >1.5 diopters (D) was separately calculated. In unilateral cases of CNLDO, sphere, astigmatism, and spherical equivalent of the eyes with CNLDO were compared with contralateral eyes in order to assess the effect of CNLDO on refractive error. In the follow-up examinations, the success of the probing or the need for additional procedures (Crawford intubation, Monoka intubation, or dacryocystorhinostomy) was evaluated. The prevalence of anisometropia between 'successful probing' and 'failed probing' groups was compared. RESULTS: A total of 433 cases were included in the study. 41 cases (9.46 %) had amblyopia risk factors. Twenty-four cases (5.5 %) had anisometropia >1.5 D (spherical or cylindrical). In unilateral cases of CNLDO, the sphere and spherical equivalent of the eyes with CNLDO were significantly greater than those of the contralateral eyes (p < 0.001 for both). Thirty-nine patients (9 %) required other interventions due to failure of probing (failed probing group). There were significantly more anisometropia prevalence in this group, compared with the successful probing group, at the initial examination (p = 0.03). CONCLUSIONS: The findings of greater prevalence of anisometropia >1.5 D (compared with the prevalence in the general population) and significantly greater sphere and spherical equivalents in the eye with CNLDO (compared with contralateral eye) in unilateral cases with CNLDO, suggested some relationships between anisometropia and long-term untreated CNLDO. The finding of more anisometropia in failed probing cases may support the theory of structural abnormality as an explanation for the possible relationship between congenital nasolacrimal duct obstruction and anisometropia.

Carvedilol compared with metoprolol on left ventricular ejection fraction after coronary artery bypass graft.

A number of elective coronary artery bypass graft (CABG) surgery patients have impaired underlying left ventricular function (poor ejection fraction). This study was performed to compare the effect of postoperative oral carvedilol versus metoprolol on left ventricular ejection fraction (LVEF) after CABG compared with metoprolol. In a double-blind clinical trial, 60 patients with coronary artery disease, aged 35 to 65 years, who had an ejection fraction of 15% to 35% were included. Either carvedilol or metoprolol was administered the day after CABG. The patients were evaluated by the same cardiologist 14 days before and 2 and 6 months after elective CABG. The results demonstrated better improvements in LVEF in the carvedilol group. No difference regarding postoperative arrhythmias or mortality was detected. The results suggest that carvedilol may exert more of an improved myocardial effect than metoprolol for the low ejection fraction patients undergoing CABG in the early postoperative months.
