Toxic epidermal necrolysis with thrombocytopenia induced by intravenous immunoglobulin: a case report and mini review.

Background: Toxic epidermal necrolysis (TEN), a severe cutaneous hypersensitivity reaction induced particularly by drugs, is diagnosed when there is a fever of ≥ 38 °C, mucocutaneous symptoms, a rash with multiple erythema, and skin peeling of ≥ 30% of the body surface area. The mortality rate of TEN is high, and thrombocytopenia during treatment can lead to severe outcomes. Intravenous immunoglobulin (IVIg) is used when steroids are ineffective in TEN and may improve mortality; however, thrombocytopenia is a rare adverse event associated with IVIg use.

Segmental phase angle can predict incidence of severe exacerbation in male patients with COPD.

Objective: To investigate whether segmental phase angle (PhA) is a useful predictor of severe chronic obstructive pulmonary disease (COPD) exacerbation.

Research Methods And Procedures: This prospective cohort study enrolled consecutive patients with COPD with a follow-up period of 3 years. The primary outcome was incidence of severe exacerbation.

Phase angle as an indicator of sarcopenia and malnutrition in patients with chronic obstructive pulmonary disease.

Background: Phase angle (PhA), which is measured using bioelectrical impedance analysis, is an indicator of muscle quality and malnutrition. PhA has been shown to be correlated with sarcopenia and malnutrition; however, studies on patients with chronic obstructive pulmonary disease (COPD) are limited. In this study, we investigated the correlation between PhA and sarcopenia and malnutrition and determined the cutoff values of PhA for those in patients with COPD.

Phase angle as an indicator of physical activity in patients with stable chronic obstructive pulmonary disease.

Objectives: Phase angle (PhA) reflects cell membrane integrity and vitality and is an indicator of sarcopenia. PhA is associated with physical function in patients with stable chronic obstructive pulmonary disease (COPD). To our knowledge, the association between PhA and physical activity (PA) has not been investigated.

Detection of varicella-zoster virus in two dermatomes of herpes zoster duplex bilateralis in an immunocompetent host.

An 85-year-old woman with no history of herpes zoster (HZ) presented with a primary lesion of erythema and blistering on her left thigh and a secondary similar lesion on her right chest which had appeared at 4 and 3 days before presentation, respectively. Tzanck smears for both lesions were positive, revealing multinucleated giant cells. Immunochromatography to detect varicella-zoster virus (VZV) antigen (DermaQuick®VZV) showed positive on the left thigh at initial onset but negative on the right chest at subsequent onset.

Possibly the first case of onychomycosis by Fusarium lactis: Case presentation and literature review of onychomycosis by Fusarium species.

Fusarium species (spp.) is frequently found in soil and plant residues and on plant bodies in all climatic zones worldwide. Although there have been few reports of onychomycosis caused by Fusarium spp.

Schimmelpenning-Feuerstein-Mims syndrome induced by HRAS Gly12Ser somatic mosaic mutation: Case report and literature review.

Schimmelpenning-Feuerstein-Mims syndrome (SFMS), an epidermal nevus disease, features skin lesions including craniofacial nevus sebaceous and extracutaneous anomalies (e.g. brain, eye, and bone).

Structural studies on C-amidated amino acids and peptides: function of amide group in molecular association in crystal structures of Val-Gly-NH2, Ser-Phe-NH2, Gly-Tyr-NH2 and Pro-Tyr-NH2 hydrochloride salts.

As part of a series of elucidation of the structural features of peptides caused by C-terminal alpha-amidation, the crystal structures of H-Val-Gly-NH2, H-Ser-Phe-NH2, H-Gly-Tyr-NH2, and H-Pro-Tyr-NH2 hydrochloride salts were analyzed by the X-ray diffraction method. Although respective molecules take energetically allowable torsion angles concerning the backbone and side chains, their conformations are not necessarily the same as the corresponding unamidated ones. This results from the different molecular packing requirements, rather than from different conformational features inherent in the C-amidated and -unamidated peptides.
