Acantholytic Dyskeratotic Acanthoma of the Nail Revealed by a Longitudinal Erythronychia.

Introduction: Focal acantholytic dyskeratosis is a distinctive histological pattern first described by Ackerman in 1972, consisting of focal suprabasal clefts in the epidermis and dyskeratotic cells at all levels of the epidermis with hyperkeratosis and parakeratosis. The first case of subungual acantholytic dyskeratosis acanthoma (ADA) was reported in 1990. This subungual variant is a very rare entity.

Dermoscopy of Lichen Planus Pigmentosus and Histopathological Correlation: A Case Series.

Introduction: Lichen planus pigmentosus (LPP) is an acquired pigmentary disorder affecting the dark-skinned population. There is a wide range of differentials, with substantial clinicopathological overlap. Dermoscopy may contribute to the better characterization of this dermatosis.

New experimental methodology for determining the second crossover energy in insulators under stationary e-irradiation in a SEM.

A new experimental methodology is proposed which uses the electrostatic influence method (EIM) in scanning electron microscope (SEM) in order to estimate the second crossover energy E for uncharged insulators. This experimental methodology based on simultaneous time measurement of the displacement and leakage currents, is approached to the short pulse irradiation technique but under stationary e-irradiation and allows determining the intrinsic secondary electron emission yield, σ (σ is the value of the total secondary electron yield just at the beginning of the irradiation before significant charge accumulation or before the formation of a surface potential). The obtained value of E for soda-lime glass is confirmed by two additional experiments based on secondary electron imaging.

Axillary hair removal with simultaneous emission of LP alexandrite 755 nm and LP Nd:YAG 1064 nm: a prospective comparative evaluation of both lasers used individually and in dual mode.

Background: Alexandrite laser is more adapted for lighter hair but not for darker skin, while the Nd:YAG laser is more suitable for darker skin but not for lighter hair.

Objective: To evaluate both laser used as single treatment and in simultaneous emission for axillary hair removal.

Method: Ten patients (18-40 years old) were selected for this study.

Physiological and growth responses of milk thistle (Silybum marianum (L.) Gaertn.) to soil-applied herbicides.

Milk thistle (Silybum marianum (L.) Gaertn.) is cultivated globally as a valuable medicinal plant.

Cutaneous Metastases: Clinicopathologic Study of 30 Patients.

Cutaneous metastases (CMs) of internal malignancies are uncommon. The breast in women and the lung in men represent the two elective sites of internal malignancies metastasizing to the skin. The aim of this study was to determine the epidemiologic, clinical, and pathologic features of CMs.

Nail involvement in connective tissue diseases: an epidemiological, clinical, and dermoscopic study.

Background: The assessment of nail changes in connective tissue diseases (CTD) has been rarely explored in previous studies. The use of dermoscopy to study vascular changes in nailfolds is an interesting diagnostic technique. The aim of the study was to describe the epidemiological, clinical, and dermoscopic features of nail lesions in CTD.

Plant extracts as an eco-friendly approach to remove paraquat from aqueous solution.

Nowadays, water pollution by herbicides is known as a global concern. Paraquat (PQ) (1-1-methyl-4,4-bi-pyridinium-dichloride) is a chip with high performance, which is being widely used herbicide to remove weeds from agricultural and natural ecosystems. PQ can contaminate water sources due to its high solubility in water.

Idiopathic Granulomatous Mastitis Associated with Erythema Nodosum in a Pregnant Woman.

A 32-year-old woman at 17 weeks' gestation presented with fever and a 1-week history of an acute nodular eruption involving her legs, along with bilateral ankle and knee pain. She also had had a recurrent right breast abscess for 2 months for which she had been treated with oral antibiotics and surgical drainage, but with slight improvement. Cultures of the abscess showed no bacteria or fungi.
