To gauge the value of total keratometry (TK) to estimate corneal power change in eyes that underwent SMILE for treatment of myopia or myopic astigmatism.
Department of Ophthalmology, Ludwig-Maximilians-University and SMILE Eyes Clinic Munich Airport, Munich, Germany.
Prospective cross-sectional trial.
A total of 40 eyes of 40 patients who had undergone myopic SMILE were enrolled in this prospective study. Total corneal refractive power (TCRP; Pentacam HR; Wetzlar, Germany) and TK (IOL Master 700; Carl Zeiss Meditec AG, Jena, Germany) values were compared to the clinical history method (CHM). The surgically induced changes in TCRP (ΔTCRP) and TK (ΔTK) were also compared to the changes in spherical equivalent on the corneal plane (ΔSEco).
The correlation between TK and CHM (R2=0.91, p<.001) was stronger than between TCRP and CHM (R2=0.87, p<.001). As compared with the CHM, TCRP underestimated corneal power by a mean relative error of 0.59 D and TK by 0.17 D. Linear regression analysis of ΔTCRP/ΔTK and the difference between preoperative and postoperative manifest refraction spherical equivalent at the corneal plane (Δ SEco) showed stronger correlation in ΔTK (R2=0.88), than in ΔTCRP (R2=0.82).
The findings endorse TK as an accurate measure for corneal power after myopic SMILE.

To validate and evaluate the use of a new biomechanical index known as the CBI-LVC (Corvis Biomechanical Index-Laser Vision Correction) as a method for separating stable post-LVC eyes from post-LVC eyes with ectasia.
Patients were included from 10 clinics/9 countries.
Retrospective, multi-center, clinical study.
The study was designed with two purposes to develop the CBI-LVC, which combines dynamic corneal response parameters (DCR) provided by a high-speed Scheimpflug camera (Corvis ST, Oculus, Germany) and then to evaluate its ability to detect post-LVC ectasia. The CBI-LVC includes Integrated Inverse Radius, Applanation 1(A1) Velocity, A1-Deflection Amplitude, Highest Concavity-dArc Length, Deformation Amplitude ratio-2mm, and A1-ArcLength mm. Logistic regression with Wald forward stepwise approach was used to identify the optimal combination of DCRs to create the CBI-LVC, and then separate stable from LVC-induced ectasia. Eighty percent of the database was used for training the software and 20% for validation.
736 eyes of 736 patients were included (685 stable LVC, and 51 post-LVC ectasia). The ROC curve analysis showed an AUC of 0.991 when applying CBI-LVC in the validation dataset and 0.998 in the training dataset. this website A cut-off of 0.2 was able to separate stable LVC from ectasia with a sensitivity of 93.3% and a specificity of 97.8%.
The CBI-LVC was highly sensitive and specific in distinguishing stable from ectatic post-LVC eyes. We suggest using CBI-LVC in routine practice, along with topography and tomography, to aid the early diagnosis of post-LVC ectasia and allow intervention prior to visually compromising progression.

At present, there are many treatment options for xeroderma pigmentosum, covering medical/procedural, surgical and combined modalities. However, the quality of these interventions has not been assessed. Our study aimed to perform a systematic review of the literature regarding the treatment of xeroderma pigmentosum. Multiple medical databases were accessed with the Medical Subject Headings terms; "xeroderma pigmentosum," "therapeutics" and "surgical procedures, operative" from January 2000 to April 2019, including articles published in Portuguese, Spanish and English (PROSPERO-CRD42018114858). Two hundred and ninety-eight studies were found in the databases researched, of which, after applying the inclusion criteria, only 33 studies remained. The 33 complete articles were read by three of the authors, having been found 16 reported medical/procedural and 17 reported surgical treatments. Only one clinical study presented a good level of evidence (EL 2) a randomized clinical trial using a T4 endonuclease V (T4N5) liposome lotion which reduced the development of skin lesions in patients with xeroderma pigmentosum. Amongst surgical modalities, all studies presented low evidence level (EL 4). Three illustrative cases are also presented, to emphasize the multiple number of times that surgical modalities may be required in these patients. The therapeutic modalities, both clinical and surgical, for xeroderma pigmentosum presented a low level of scientific evidence which did not allow meta-analysis. More therapeutic studies, both clinical and surgical, with better scientific evidence are needed.Dermatophytosis has attained unprecedented dimensions in recent years in India. Its clinical presentation is now multifarious, often with atypical morphology, severe forms and unusually extensive disease in all age groups. We hesitate to call it an epidemic owing to the lack of population-based prevalence surveys. In this part of the review, we discuss the epidemiology and clinical features of this contemporary problem. While the epidemiology is marked by a stark increase in the number of chronic, relapsing and recurrent cases, the clinical distribution is marked by a disproportionate rise in the number of cases with tinea corporis and cruris, cases presenting with the involvement of extensive areas, and tinea faciei.
Erythema nodosum leprosum (ENL) is a frequent complication of multibacillary leprosy that can result in significant morbidity, including peripheral nerve damage and physical disability. The identification of possible serum markers could be a valuable tool for the early detection of ENL.
The purpose of this study was to evaluate selected serum mediators involved in the innate and adaptive immune responses to identify possible immunomarkers for ENL.
The levels of interleukin-2, interleukin-4, interleukin-6, interleukin-10, interleukin-17, interferon-γ, tumor necrosis factor, nitric oxide and anti-phenolic glycolipid-I antibodies were measured in the sera of leprosy patients with ENL [at the beginning of reaction (M0) and 1 month later (M1)], and then compared with the levels of the same markers in patients with untreated multibacillary leprosy without ENL (controls with leprosy CTRL) and healthy individuals (healthy controls CTRH).
Significantly higher levels of serum interleukin-6 were observed in M0 than in CTRL.
