RESUMEN

Endometrial cancer (EC) is the fourth most common cancer in women in developed countries. Although it is usually diagnosed in postmenopausal women, its incidence has increased in young women, as well in recent decades, with an estimated rate of 4% in those under 40 years of age. Factors involved in this increase, particularly in resource-rich countries, include delayed childbearing and the rise in obesity. The new molecular classification of EC should help to personalize treatment, through appropriate candidate selection. With the currently available evidence, the use of oral progestin either alone or in combination with other drugs such as metformin, levonorgestrel-releasing intrauterine devices and hysteroscopic resection, seems to be feasible and safe in women with early-stage EC limited to the endometrium. However, there is a lack of high-quality evidence of the efficacy and safety of conservative management in EC. Randomized clinical trials in younger women and obese patients are currently underway.

RESUMEN

A pathologic complete response (pCR) in the axilla occurs in 30%-40% of patients with initially node-positive breast cancer after neo-adjuvant chemotherapy (NACT). Debate persists about whether to perform systematic axillary lymphadenectomy (ALND) in patients with initial node-positive disease and clinical complete response after NACT. We aimed to identify predictive factors of axillary pCR (ypN0) after NACT. This retrospective study analyzed data for all patients with initial biopsy-proven node-positive disease who underwent ALND after NACT between June 2008 and December 2016 at our institution. Clinical and pathologic features, recurrence and specific mortality rates were compared between patients who achieved an axillary pCR and those who did not (ypN0 vs ypN+, respectively). A total of 331 patients were included, of whom 128 (38.7%) became ypN0 after NACT. Among patients with >2 suspicious axillary lymph nodes before treatment, 54 (38%) achieved ypN0 status. The independent predictors of ypN0 were Ki-67 > 30 (OR 1.98; 95% CI, 1.146-3.381), HER2 positivity (OR 2.6; 95% CI, 1.354-5.108), nonluminal molecular-like subtype (OR 4.15; 95% CI, 2.068-5.108), and clinical complete response, defined as negative clinical and ultrasonographic findings (OR 2.8; 95% CI, 1.110-7.081). After a mean follow-up of 61 months, distant disease-free and overall survival rates were higher in patients with ypN0 disease (HR 4.14; 95% CI, 2.03-8.43) than ypN+ patients. Complete clinical response and the presence of nonluminal molecular-like subtypes independently predicted ypN0. Patients meeting these criteria might be suitable form omitting ALND and just performing targeted axillary procedures to patients meeting these criteria.

RESUMEN

OBJECTIVE: Case report of a 7-year-old male patient, diagnosed with idiopathic progressive corneal alteration developed within a period of 6 months. METHODS: Description of type 2 distal arthrogryposis affecting hands and feet, a bilateral, congenital hearing loss, alterations such as keloid-like scarring, congenital heart disease, and cryptorchidism with no relevant family history. RESULTS: Corrected visual acuity in the right eye (RE) was 0.5 and in the left eye was 1 and, in addition to that, a bilateral corneal subepithelial fibrosis that was denser in the RE without neovessels and no signs of inflammatory activity. CONCLUSION: This is the first publication relating arthrogryposis with corneal affectation, probably because of a collagen anomaly characteristic in these patients.

RESUMEN

PURPOSE: To present a case of a late, deep stromal scar in a 22-year-old patient with forme fruste keratoconus who underwent combined corneal cross-linking and photorefractive keratectomy (PRK). METHODS: Topography-guided corneal cross-linking combined with corneal PRK (without complications) was performed in both eyes with a delay of 2 weeks between each eye. RESULTS: At the 5-month postoperative examination of the right eye, a localized corneal haze was circumscribed to the posterior deep stroma, signifying a decrease of visual acuity. However, this improved partially and temporarily when treated with topical corticoids during 2 years of follow-up and then reoccurred, affecting the corrected distance visual acuity. CONCLUSIONS: To the authors' knowledge, this is the first documented, clinical case presenting a deep stromal affectation without endothelial decompensation and visual acuity affectation as a postoperative complication following topography-guided PRK and corneal cross-linking.

RESUMEN

PURPOSE: To evaluate the rates of retinal reattachment and the closure of myopic macular hole because of posterior pole retinal detachment after treatment with pars plana vitrectomy and subsequent dissection of the inner limiting membrane. METHODS: Prospective noncomparative study of 27 eyes from 27 phakic patients diagnosed with posterior pole retinal detachment as a result of myopic macular hole. All underwent pars plana vitrectomy with dissection of the inner limiting membrane and intravitreal silicone oil tamponade performed by the same surgeon. The main variables assessed were visual acuity, retinal reattachment, and macular hole closure determined by optical coherence tomography. RESULTS: Of the 27 eyes, 16 (59.3%) were right eyes and 11 (40.7%) were left eyes. Mean age was 50.5 years. Myopia ranged from -9 diopters (D) to -27 diopters (mean, -18 diopters), and axial length ranged from 28.5 mm to 35.6 mm (mean, 32.05 mm). After a mean postoperative period of 12 months, retinal reattachment was found in 85.1% of the patients and anatomical closure of the macular hole in 51.9%. CONCLUSION: This technique offers good rates of retinal reattachment and macular hole closure, although seldom increases the final visual acuity. It showed limited effectiveness in eyes with an axial length >30 mm.

RESUMEN

PURPOSE: To perform a paired-eye comparison of secondary iris-claw intraocular lens (IOL) implantation for aphakia. METHODS: Retrospective, comparative, nonrandomized interventional case series of aphakic eyes, which underwent secondary iris-claw Artisan IOL (Ophtec BV) implantation for aphakia in one eye and no surgery (group 1) or cataract surgery (group 2) in the fellow eye. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent, central endothelial cell count (cECC), and complications were evaluated before surgery, and at yearly intervals up to 5 years. RESULTS: Thirty aphakic eyes implanted with the Artisan were included, and the fellow eyes served as controls. In group 1, postoperative logMAR UDVA and CDVA was significantly higher in the Artisan-implanted eyes (P < 0.01). In group 2, no differences were found in postoperative UDVA and postoperative CDVA between the Artisan-implanted eyes and the eyes that underwent cataract surgery throughout the follow-up (P ≥ 0.05). No statistically significant differences were found in postoperative spherical equivalent between the Artisan-implanted eyes and unoperated eyes or eyes that underwent cataract surgery (P ≥ 0.05). In group 1, cECC was significantly lower in the Artisan-implanted eyes [1973 ± 822 vs. 2616 ± 481 cells per square millimeter at 2 years (P < 0.01)] throughout the follow-up (P < 0.01). In group 2, cECC was not significantly lower in the Artisan-implanted eyes (P ≥ 0.05) [1934 ± 689 vs. 2058 ± 818 cells per square millimeter at 2 years (P = 0.67)]. CONCLUSIONS: Visual rehabilitation with secondary iris-claw IOL implantation in aphakic eyes without capsular support seems to be an effective and safe procedure. As expected, uncomplicated cataract surgery with posterior chamber IOL implantation showed lower endothelial cell count loss. Close monitoring of the corneal endothelium is mandatory.

RESUMEN

PURPOSE: To describe a case of hydrophilic intraocular lens (IOL) opacification based on IOL analysis after Descemet stripping automated endothelial keratoplasty. METHODS: A 60-year-old woman had uneventful phacoemulsification after the implantation of a hydrophilic IOL (Akreos-Adapt; Bausch & Lomb) into both eyes. Because of postoperative corneal decompensation in the right eye, 2 Descemet stripping automated endothelial keratoplasty operations were performed within 1 year. After the second procedure, the graft was not well attached, requiring an intracameral injection of air on day 3. After 1 year, opacification was observed on the superior 2/3 of the anterior surface of the IOL, along with a significant decrease in visual acuity. The IOL was explanted 6 months after the opacification. RESULTS: Environmental scanning electron microscopy followed by x-ray microanalysis revealed an organic biofilm on the surface of the IOL. CONCLUSIONS: To our knowledge, this is the first reported case in which the material deposited on the lens is organic rather than calcific.

RESUMEN

PURPOSE: To define the role of increased fundus autofluorescence (FAF), a surrogate for lipofuscin content, as a risk factor for progression of geographic atrophy (GA). DESIGN: Prospective natural history cohort study, the GAIN (Characterization of geographic atrophy progression in patients with age-related macular degeneration). METHODS: setting: Single-center study conducted in Barcelona, Spain. PATIENTS: After screening of 211 patients, 109 eyes of 82 patients with GA secondary to age-related macular degeneration and a minimum follow-up of 6 months were included. OBSERVATION PROCEDURES: Lipofuscin content was classified independently by 2 masked observers according to FAF patterns described previously. Bivariate, stratified, and multivariable analyses were used to explore the associations between GA growth and independent variables. Mediation analysis was used to evaluate the contribution of FAF patterns to GA progression. MAIN OUTCOME: Progression of GA in mm(2)/year as measured with FAF. RESULTS: Median follow-up was 18 months (range, 6-42). Median GA growth was 1.61 mm(2)/year. FAF, baseline area of atrophy, and time of follow-up were independently associated with GA progression (P < .004). FAF patterns and baseline area of atrophy were strongly associated (P < .0001), suggesting potential confounding. Mediation analysis suggested that most of the effect of FAF patterns on GA growth was actually caused by baseline area of atrophy. CONCLUSIONS: FAF patterns, baseline area of atrophy, and time of follow-up were associated with GA progression. However, FAF patterns seem to be a consequence (not a cause) of enlarging atrophy and their effect on GA progression seems mostly driven by baseline area of atrophy.

RESUMEN

PURPOSE: To study the feasibility of performing myopic femtosecond small incision lenticule extraction (SMILE) with four different cap thicknesses (130, 140, 150, and 160 µm). METHODS: In this retrospective, comparative, non-randomized clinical trial, a refractive lenticule of intrastromal corneal tissue was cut with the VisuMax femtosecond laser system (Carl Zeiss Meditec AG, Jena, Germany) using different depths of the non-refractive lenticule cut. Manifest refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and Objective Scattering Index (OSI) were evaluated. Minimum follow-up time was 1 year. RESULTS: Ninety-four eyes of 47 patients with myopia with (14 patients) and without (33 patients) astigmatism were treated. One year after the surgery, mean log-MAR UDVA, logMAR CDVA, SE, and OSI were 0.07 ± 0.12, 0.01 ± 0.37, 0.07 ± 0.57, and 0.88 ± 0.17, respectively (P < .05). There were no significant statistical differences in logMAR UDVA, logMAR CDVA, SE, or OSI (P > .05) variables when the different groups were compared for the same periods of time. CONCLUSIONS: No differences in visual acuity, refractive outcomes in optical visual quality, or complications were observed when using SMILE at four different depths.

RESUMEN

BACKGROUND/AIMS: To evaluate the efficacy, predictability, safety and complications of secondary iris-claw intraocular lens (IOL) implantation in aphakic eyes without capsular support. METHODS: Retrospective, non-comparative, interventional case series of 128 aphakic eyes, which consecutively underwent secondary iris-claw Artisan IOL (Ophtec BV) implantation, were included. Manifest refraction, uncorrected visual acuity, best-spectacle corrected visual acuity, biomicroscopy, tonometry, funduscopy and central endothelial cell count (cECC) were evaluated before surgery, and at yearly intervals up to 5 years. Minimum follow-up time was 1 year. RESULTS: One hundred twenty-eight eyes were treated. Mean age was 54.55 years (range, 1-98 years). Mean follow-up was 41.8 months (SD 23.63). Mean preoperative logarithm of the minimum angle of resolution BSCVA and spherical equivalent (SE) were 0.67 ((SD) 0.53) and 9.63 D (SD 5.50), respectively. One year postoperatively, mean logarithm of the minimum angle of resolution best-spectacle corrected visual acuity improved to 0.52 (SD 0.46) (p<0.05), and remained stable up to 5 years. One year postoperatively, mean SE was -0.52 (SD 2.21) (p<0.05). Mean SE progressively decreased during the 1st year, and remained stable thereafter (p<0.05). Mean preoperative cECC was 2237.47 (SD 793.33) cells/mm(2). cECC showed a slight, though statistically significant, decrease over the years (p=0.05). Main complications were: 2 pupillary block; 3 transient increase in intraocular pressure; 1 IOL replacement; 2 penetrating keratoplasty and 4 cystoid macular oedema. CONCLUSIONS: Iris-claw IOL implantation in aphakic eyes is an effective, predictable and safe procedure in the first 5 years of follow-up. However, a longer follow-up is required to demonstrate its long-term safety.

RESUMEN

PURPOSE: The aim was to study the visual and refractive results in patients with epithelization in the corneal interface after laser in situ keratomileusis (LASIK) who were treated by cleaning the corneal interface (epithelial cyst extraction) and suturing the corneal flap. METHODS: This is a retrospective, noncomparative interventional case series. The main outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive cylinder (CYL), spherical equivalent (SE), recurrence of epithelial ingrowth, and complications. RESULTS: From a total of 7520 LASIK refractive eyes, 13 eyes with epithelial ingrowth were treated. The mean age was 46.9 years. The mean preoperative logMAR UDVA was 0.34 (SD, 0.19). At 2 months, the mean postoperative logMAR UDVA was 0.18 (SD, 0.17) and at 1 year was 0.12 (SD, 0.18) (P = 0.01). The mean logMAR CDVA before surgery was 0.16 (SD, 0.16). Two months and 1 year postoperatively, the mean logMAR CDVA was 0.05 (SD, 0.08) and 0.03 (SD, 0.06), respectively (P = 0.03). The mean SE before surgery was 0.30 D (SD, 1.09). The mean SE 2 months and 1 year after surgery was -0.07 (SD, 0.53) and -0.004 (SD, 0.18), respectively (P = 0.04). The mean CYL before surgery was -0.92 D (SD, 1.09); and the mean CYL 2 months and 1 year after surgery was -0.60 (SD, 0.84) and -0.18 (SD, 0.75), respectively (P = 0.26). No epithelial ingrowth recurrence was observed up to 1 year after epithelial removal. CONCLUSIONS: Cleaning the corneal interface and suturing the corneal flap was effective and appeared safe in treating epithelial ingrowth after LASIK, with an extremely low rate of regrowth. However, further prospective controlled studies with a longer follow-up are needed.

RESUMEN

PURPOSE: To describe the diagnosis and management of an intraretinal cyst. CASE REPORT: A 34-year-old man with a history of retinal detachment presented sudden loss of vision in the left eye. Visual acuity was hand movement. Examination revealed hematic vitreous haze and ultrasound showed a rounded mobile object in the vitreous cavity. RESULTS: After differential diagnosis ruled out cysticercosis, pars plana vitrectomy revealed a neovascularized intraretinal macrocyst attached to a posterior flap of a 13-year-old retinal tear. Retinotomy and retinectomy were performed, removing this cyst located in the upper retina together with a portion of detached retina. At 1 year, the retina had adapted and the vitreous cavity was clear. Final visual acuity was 18/20. CONCLUSIONS: Intraretinal cysts are usually asymptomatic and associated with long-standing retinal detachment, as seen in our clinical case. Periodic fundus examination is essential for their detection. Surgical treatment of the underlying condition usually leads to complete resolution.

RESUMEN

UNLABELLED: We present a 14-year-old boy with a history of advanced keratoconus in the left eye. Two 400 µm intrastromal corneal ring segments (ICRS) (Intacs) were implanted on the 140-degree meridian at a depth of 400 µm in the left eye using the suction-guided manual dissection technique. While the temporal segment was being implanted, a probable break in Descemet membrane occurred, allegedly opening during the hours after surgery; acute corneal hydrops was observed on the following day. We have no knowledge of an ICRS implantation case that experienced acute hydrops due to a break in Descemet membrane without perforation of the anterior chamber; ie, without allowing aqueous humor through the corneal internal incision.
