Coronary CT angiography: a guide to examination, interpretation, and clinical indications
2021
Introduction: The introduction of Cardiac Computed Tomography (CCT) has changed the paradigm in the field of diagnostic cardiovascular medicine. CCT is the primary tool in the assessment of suspected Coronary Artery Disease (CAD) and should be followed by functional assessment when needed to stratify disease and to plan potential interventional or surgical therapy. Areas Covered: We provided the current state of the knowledge on the main aspects of technique of examination, image interpretation and clinical indications. We have focused our attention on the basic routine applications and activities. Expert Opinion: The primary role of CCT in suspected CAD will progressively become the standa…
Evaluating resurfacing modalities in aesthetics.
2022
Abstract Skin resurfacing for cutaneous rejuvenation has evolved with the development of a plethora of nonsurgical and minimally invasive modalities. We have highlighted the advances in laser therapy, chemical peels, radiofrequency, microneedling, and platelet-rich plasma therapy. We have also included studies providing head-to-head comparisons between procedures and discussed relevant debates in the field. We have examined additionally combination treatments and resurfacing in acne scars, melasma, and skin of color.
Effects of Superficial Keratectomy in Peripheral Hypertrophic Subepithelial Corneal Opacification on Front and Back Corneal Astigmatism
2020
To evaluate changes of anterior and posterior corneal astigmatism after superficial keratectomy in peripheral hypertrophic subepithelial corneal opacification (PHSCO). Patients with PHSCO, who had ...
Differentiation of frontal fibrosing alopecia and Lichen planopilaris on trichoscopy: A comprehensive review.
2021
Trichoscopy in dermatology has opened up the new concept in overcoming the optical challenge faced clinically. It reveals the diagnostic details to the depth of superficial dermis, and thereby increasing the clinician's diagnostic accuracy and the level of confidence. The importance of trichoscopy in cicatricial alopecia is very evident in the current scenario for its precise diagnosis. The clinical picture in delineating lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) from each other and also from other close mimickers such as androgenetic alopecia, alopecia areata, female patterned hair loss, and other cicatricial alopecia is bewildered due to its varied presentation and co…
Analysis of skin basalioma and melanoma by multispectral imaging
2012
A clinical trial involving multi-spectral imaging of histologically confirmed 8 basaliomas and 30 melanomas was performed. Parametric maps of the melanin index, erythema index and melanoma-nevus differentiation parameter have been constructed and mutually compared. Specific features of basalioma and melanoma images were analyzed and discussed.
Rosacea assessment by erythema index and principal component analysis segmentation maps
2017
RGB images of rosacea were analyzed using segmentation maps of principal component analysis (PCA) and erythema index (EI). Areas of segmented clusters were compared to Clinician’s Erythema Assessment (CEA) values given by two dermatologists. The results show that visible blood vessels are segmented more precisely on maps of the erythema index and the third principal component (PC3). In many cases, a distribution of clusters on EI and PC3 maps are very similar. Mean values of clusters’ areas on these maps show a decrease of the area of blood vessels and erythema and an increase of lighter skin area after the therapy for the patients with diagnosis CEA = 2 on the first visit and CEA=1 on the …

Alopecia areata and isotretinoin; coincidence or causal relation
2020
Isotretinoin is a safe and useful medication for acne management. Adverse effects are mostly related to cutaneous and mucous membranes. We present a case of a 24-year-old female patient who was on treatment with isotretinoin for acne vulgaris Grade 4. After 6 months of treatment, the patient presented with localized patch of hair loss. Beginning of alopecia areata in patients with acne vulgaris could be regarded as a side effect of retinoids due to anti-acne therapy. The exact mechanism by which retinoids cause hair loss is not known.
Non-invasive LED-based screening solution for skin cancer
2019
Skin cancer is the most common type of malignant tumors in humans. Early diagnosis is the key to successful surgical treatment. In this work we present a non-invasive screening tool for early stage detection of skin cancer and also for the evaluation of post-operative scars.
Spectral imaging as a tool for the evaluation of skin cancer post-operative scars
2020
Skin cancer is the most common type of cancer in the USA and worldwide.1 An early diagnosis is the key to a successful treatment. Among the skin cancers, the malignant melanoma (MM) accounts for 1% of the cases while it is responsible for the majority of deaths. Basal cell carcinoma (BCC) is the most common form of skin cancer with a very low mortality rate.2 Unfortunately, skin cancer recurrence is a common problem for MM and BCC patients. We propose a post-operative scar screening with non-invasive autofluorescence (AF) imaging to detect an early growth of any residual tissue from the cancer removal procedure. The screening images can serve also as a visual evidence for the post-op patien…
