Abstract PurposeTo describe and compare the clinical features and management of different types of acute diplopia of non-neurological/restrictive etiology.MethodsRetrospective comparative study carried out reviewing medical records of forty-eight patients referred to one tertiary referral center between January 2016 and June 2020.Thirty-two were classified as Acute Acquired Comitant Esotropia (AACE), 3 cases as type I (group A), 12 cases as type II (group B) and 17 cases as type III (group C). Four cases were classified as Decompensated MonoFixation Syndrome (DMFS) (group D), 6 cases as High Myopia-Comitant Esotropia (HMCE) (group E) and 6 cases as Sagging Eye Syndrome (SES) (group F). Patients with diplopia of neurological or restrictive etiology were excluded.All patients underwent a complete orthoptic and ophthalmologic assessment with a postoperative follow-up of 11.4 ± 4.1 months (ranging from 5 to 20 months).ResultsType 3 AACE (Group C) was the most frequent cause of diplopia among the groups (35.4%). High Myopia-Comitant Esotropia (Group E) and Sagging Eye Syndrome (Group F) were significantly older at onset and baseline examination (both P= .001). Constant acute onset was significantly more represented in Group C (P= .026) while all patients in Group F showed an intermittent onset. Near angle of deviation was significantly lower in Group E and Group F compared to Group C (P= .030). A significantly higher near divergence fusion amplitude was detected in Group C (P= .017). Compensation (angle of deviation increasing) at Prism Adaptation Test (PAT) was observed in 75% of total study population, without significant differences among group. Fifty-four % of the total sample underwent surgery as first or secondary treatment choice with good functional results regardless of pathogenesis.ConclusionDemographic characteristics and clinical features (refraction, type of diplopia at onset, angle deviation, fusion amplitudes, response to prismatic correction) can differentiate different types of acute or subacute onset diplopia of not neurological/restrictive etiology.

Endoscopic Tympanoplasty

Abstract Introduction The use of endoscope is rapidly increasing in otological and neuro-otological surgery in the last 2 decades. Middle ear surgeries, including tympanoplasty, have increasingly utilized endoscopes as an adjunct to or as a replacement for the operative microscope. Superior visualization and transcanal access to diseases normally managed with a transmastoid approach are touted as advantages with the endoscope. Objectives The present study aimed to compare the outcomes of endoscopic and microscopic cartilage tympanoplasty (Type I) Methods This was a retrospective comparative study of 70 patients (25 males and 45 females) who underwent type I tympanoplasty between March 2015 and April 2016. The subjects were classified into 2 groups: endoscopic tympanoplasty (ET, n = 35), and microscopic tympanoplasty (MT, n = 35). Tragal cartilage was used as a graft and technique used was cartilage shield tympanoplasty in both groups. Demographic data, perforation size of the tympanic membrane at the preoperative state, operation time, hearing outcome, and graft success rate were evaluated. Results The epidemiological profiles, the preoperative hearing status, and the perforation size were similar in both groups. The mean operation time of the MT group (52.63 ± 8.68 minutes) was longer than that of the ET group (48.20 ± 10.37 minutes), but the difference was not statistically significant. The graft success rates 12 weeks postoperatively were 91.42% both in the ET and MT groups, that is, 32/35; and these values were not statistically significantly different. There was a statistically significant improvement in hearing within the groups, both pre- and postoperatively, but there was no difference between the groups. Conclusion Endoscopic tympanoplasty is a minimally invasive surgery with similar graft success rate, comparable hearing outcomes and shorter operative time period as compared to microscopic use.

Objectives To analyze embryological development of the ethmoidal fovea and the horizontal ethmoidal plate and measure the thickness of the latter during the various stages of gestation, and whether to determine if, during the intrauterine life, there are different types of fovea according to the Keros classification. Methods A retrospective, descriptive, and comparative study was made using 92 human fetuses. Morphometry was made and inferential statistics and correlations and autocorrelations during different stages were done. Results The morphological structures of the fovea are recognized during the 14th week. In 32-week-old fetuses measurements of the fovea did not vary in proportion to the rest of the structures. In all the specimens studied, the type of roof was type I, agreeing with Keros' classification. As for the measurements of the thickness of the fovea, width and length of the crista Galli apophysis, they were significant (p <0,001), strongly supporting their growth in relation to the crown-caudal length. Conclusions As for the various anatomic variants that are observed in the adults, according to Keros' classification, there were no variants in all the fetuses studied as such variants we can assure, at least in the population studied, that these appear until after birth upon development of the middle third of the face.

Fibers composed of different types of collagen cannot be differentiated by conventional electron microscopic stains. We are developing staining procedures aimed at identifying collagen fibers of different types.Pt(Gly-L-Met)Cl binds specifically to sulfur-containing amino acids. Different collagens have methionine (met) residues at somewhat different positions. A good correspondence has been reported between known met positions and Pt(GLM) bands in rat Type I SLS (collagen aggregates in which molecules lie adjacent to each other in exact register). We have confirmed this relationship in Type III collagen SLS (Fig. 1).

SUMMARYThe ability of six different types of contamination control mats currently in use at the entrances to theatre suites and other clean areas to remove bacteria-carrying particles from theatre trolley wheels was compared. Marked differences in the effectiveness of this property were obtained; and all mats showed some disadvantages. Modification of one of the mats has resulted in improved efficiency under working conditions.
